It is recommended to refrain from swimming until a perforated tympanic membrane has fully healed, which typically takes longer than a week. Using a swimming cap may not offer adequate protection. Antibiotics should only be prescribed if there is an infection present, and oral antibiotics are preferred over drops.

Perforated Tympanic Membrane: Causes and Management

A perforated tympanic membrane, also known as a ruptured eardrum, is often caused by an infection but can also result from barotrauma or direct trauma. This condition can lead to hearing loss and increase the risk of otitis media.

In most cases, no treatment is necessary as the tympanic membrane will typically heal on its own within 6-8 weeks. However, it is important to avoid getting water in the ear during this time. Antibiotics may be prescribed if the perforation occurs after an episode of acute otitis media. This approach is supported by the 2008 Respiratory Tract Infection Guidelines from NICE.

If the tympanic membrane doesn’t heal by itself, myringoplasty may be performed. This surgical procedure involves repairing the perforation with a graft of tissue taken from another part of the body. With proper management, a perforated tympanic membrane can be successfully treated and hearing can be restored.

Horizontal nystagmus is a common symptom of vestibular neuronitis, which is caused by inflammation of the vestibular nerve. This condition typically presents with vertigo, nausea, vomiting, and balance problems, but doesn’t cause hearing loss as the cochlear nerve is not affected. The presence of horizontal nystagmus helps to rule out a central cause of vertigo, such as a stroke.

Acoustic neuroma, on the other hand, is characterized by a tumor that compresses the eighth cranial nerve, leading to symptoms such as vertigo, hearing loss, tinnitus, and an absent corneal reflex. Meniere’s disease is another condition that causes sudden episodes of vertigo, hearing loss, and tinnitus, but also involves a sensation of fullness in the ears due to an abnormal amount of endolymph in the inner ear. However, the absence of tinnitus in the patient in the vignette makes these diagnoses less likely.

A posterior circulation stroke can also cause nystagmus, vertigo, and nausea, but these symptoms typically come on suddenly and are accompanied by ataxia, unilateral limb weakness, and an altered mental state. In addition, a central cause of vertigo would result in vertical nystagmus rather than horizontal nystagmus.

Viral labyrinthitis is similar to vestibular neuronitis, but is more likely to cause hearing loss and tinnitus. In vestibular neuronitis, only the vestibular nerve is affected, while hearing is spared.

Understanding Vestibular Neuronitis

Vestibular neuronitis is a type of vertigo that typically occurs after a viral infection. It is characterized by recurrent episodes of vertigo that can last for hours or days, accompanied by nausea and vomiting. Horizontal nystagmus is also a common symptom, but there is no hearing loss or tinnitus.

It is important to differentiate vestibular neuronitis from other conditions such as viral labyrinthitis and posterior circulation stroke. The HiNTs exam can be used to distinguish between these conditions.

Treatment for vestibular neuronitis typically involves medication to alleviate symptoms, such as buccal or intramuscular prochlorperazine for severe cases, or a short course of oral medication for less severe cases. Vestibular rehabilitation exercises are also recommended for patients who experience chronic symptoms.

Understanding the symptoms and treatment options for vestibular neuronitis can help individuals manage this condition and improve their quality of life.

The typical presentation of vestibular schwannoma involves a combination of symptoms such as vertigo, hearing loss, tinnitus, and an absent corneal reflex. On the other hand, the symptoms of acoustic neuroma may vary depending on the cranial nerve affected. In this case, the patient’s tinnitus and hearing loss suggest that the vestibulocochlear nerve is affected, and vertigo may also be present. Sensorineural hearing loss is observed in acoustic neuroma, whereas otosclerosis, impacted wax, and cholesteatoma cause conductive hearing loss. Meniere’s disease is characterized by progressive hearing loss that fluctuates in severity depending on the attacks.

Vestibular schwannomas, also known as acoustic neuromas, make up about 5% of intracranial tumors and 90% of cerebellopontine angle tumors. These tumors typically present with a combination of vertigo, hearing loss, tinnitus, and an absent corneal reflex. The specific symptoms can be predicted based on which cranial nerves are affected. For example, cranial nerve VIII involvement can cause vertigo, unilateral sensorineural hearing loss, and unilateral tinnitus. Bilateral vestibular schwannomas are associated with neurofibromatosis type 2.

If a vestibular schwannoma is suspected, it is important to refer the patient to an ear, nose, and throat specialist urgently. However, it is worth noting that these tumors are often benign and slow-growing, so observation may be appropriate initially. The diagnosis is typically confirmed with an MRI of the cerebellopontine angle, and audiometry is also important as most patients will have some degree of hearing loss. Treatment options include surgery, radiotherapy, or continued observation.

Bell’s palsy results in complete paralysis on one side of the face as it affects the lower motor neurones. In contrast, upper motor neurone-related conditions like stroke spare the forehead, which exhibits some wrinkling due to the bilateral nerve innervation of the forehead by upper motor neurones.

Bell’s palsy is a sudden, one-sided facial nerve paralysis of unknown cause. It typically affects individuals between the ages of 20 and 40, and is more common in pregnant women. The condition is characterized by a lower motor neuron facial nerve palsy that affects the forehead, while sparing the upper face. Patients may also experience post-auricular pain, altered taste, dry eyes, and hyperacusis.

The management of Bell’s palsy has been a topic of debate, with various treatment options proposed in the past. However, there is now consensus that all patients should receive oral prednisolone within 72 hours of onset. The addition of antiviral medications is still a matter of discussion, with some experts recommending it for severe cases. Eye care is also crucial to prevent exposure keratopathy, and patients may need to use artificial tears and eye lubricants. If they are unable to close their eye at bedtime, they should tape it closed using microporous tape.

Follow-up is essential for patients who show no improvement after three weeks, as they may require urgent referral to ENT. Those with more long-standing weakness may benefit from a referral to plastic surgery. The prognosis for Bell’s palsy is generally good, with most patients making a full recovery within three to four months. However, untreated cases can result in permanent moderate to severe weakness in around 15% of patients.

Understanding Otitis Media with Effusion (Glue Ear)

Otitis media with effusion, commonly known as glue ear, is a condition characterized by inflammation of the middle ear and the accumulation of fluid in the middle-ear cleft. This condition is prevalent in young children, with most experiencing at least one episode during early childhood. Although most episodes are brief, symptoms such as earache and hearing loss can occur. Hearing loss can be significant, especially if it persists for more than a month and affects both ears. However, not all cases of glue ear present with hearing loss.

It is important to note that a normal-looking eardrum doesn’t necessarily exclude the possibility of OME. Otoscopic features of OME may include opacification of the drum, loss of the light reflex, indrawn or retracted drum, decreased mobility of the drum, bubbles or fluid level behind the drum, yellow or amber color change to the drum, and fullness or bulging of the drum. It is worth noting that acute otitis media may also present with earache and hearing loss, and the eardrum may appear redder and bulge.

In conclusion, understanding the symptoms and signs of OME is crucial in diagnosing and managing this condition. If you suspect that you or your child may have glue ear, seek medical attention promptly.

Factors to Consider When Prescribing Antibiotics for Respiratory Infections

When considering prescribing antibiotics for respiratory infections, it is important to take into account various risk factors that may increase the likelihood of complications. While antibiotics may be necessary in some cases, their use should be weighed against potential adverse effects and the development of antibiotic-resistance patterns.

One factor to consider is hoarseness and/or laryngitis accompanying the cough. In most cases, laryngitis is mild and self-limiting, and antibiotics may not be necessary. However, they may be considered in patients with persistent symptoms.

Another factor to consider is a history of congestive cardiac failure. For patients between 65 and 79 years, two risk factors should be present before prescribing antibiotics.

Current use of oral glucocorticoids is also a risk factor, as these patients are immunosuppressed and may be more susceptible to complications from respiratory infections.

Diabetes and hospitalization in the previous year are also risk factors for complications and should be taken into account when considering antibiotic prescriptions.

Overall, it is important to carefully evaluate each patient’s individual risk factors before deciding whether antibiotics are necessary for the treatment of respiratory infections.

Otosclerosis, which is an inherited condition, can cause hearing loss in young adults. The symptoms of slowly progressing bilateral conductive hearing loss and a positive family history are typical of otosclerosis.

Presbyacusis, on the other hand, is a type of hearing loss that occurs with aging and is unlikely to affect a young woman. Sensorineural hearing loss is caused by acoustic neuroma, while Meniere’s disease is characterized by episodes of vertigo.

Understanding Otosclerosis: A Progressive Conductive Deafness

Otosclerosis is a medical condition that occurs when normal bone is replaced by vascular spongy bone. This condition leads to a progressive conductive deafness due to the fixation of the stapes at the oval window. It is an autosomal dominant condition that typically affects young adults, with onset usually occurring between the ages of 20-40 years.

The main features of otosclerosis include conductive deafness, tinnitus, a normal tympanic membrane, and a positive family history. In some cases, patients may also experience a flamingo tinge, which is caused by hyperemia and affects around 10% of patients.

Management of otosclerosis typically involves the use of a hearing aid or stapedectomy. A hearing aid can help to improve hearing, while a stapedectomy involves the surgical removal of the stapes bone and replacement with a prosthesis.

Overall, understanding otosclerosis is important for individuals who may be at risk of developing this condition. Early diagnosis and management can help to improve hearing and prevent further complications.

If there is a sensorineural issue, the sound in Weber’s test will be perceived on the healthy side (left), suggesting a problem on the affected side (right).

Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness

Rinne’s and Weber’s tests are used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus. A positive test indicates that air conduction (AC) is better than bone conduction (BC), while a negative test indicates that BC is better than AC, suggesting conductive deafness.

Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking the patient which side is loudest. In unilateral sensorineural deafness, sound is localized to the unaffected side, while in unilateral conductive deafness, sound is localized to the affected side.

The table below summarizes the interpretation of Rinne and Weber tests. A normal result indicates that AC is greater than BC bilaterally and the sound is midline. Conductive hearing loss is indicated by BC being greater than AC in the affected ear and AC being greater than BC in the unaffected ear, with the sound lateralizing to the affected ear. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, with the sound lateralizing to the unaffected ear.

Overall, Rinne’s and Weber’s tests are useful tools for differentiating between conductive and sensorineural deafness, allowing for appropriate management and treatment.

Children who have glue ear and also have Down’s syndrome or cleft palate should be referred to an ENT specialist. While most children with otitis media with effusion (OME) can be observed for 6-12 weeks, those with Down’s syndrome or cleft palate are less likely to recover on their own. It is important to follow up with all patients with OME, even if they do not meet the criteria for referral to ENT.

Antibiotics, antihistamines, and corticosteroids should not be prescribed for OME as there is no evidence to support their use. If the patient did not have Down’s syndrome, it would be appropriate to recheck their ears after 6-12 weeks and refer to ENT if the OME had not resolved. During this observation period, normal activities including swimming (except for diving) should be encouraged.

Understanding Glue Ear

Glue ear, also known as serous otitis media, is a common condition among children, with most experiencing at least one episode during their childhood. It is characterized by the accumulation of fluid in the middle ear, leading to hearing loss, speech and language delay, and behavioral or balance problems. The risk factors for glue ear include male sex, siblings with the condition, bottle feeding, day care attendance, and parental smoking. It is more prevalent during the winter and spring seasons.

The condition typically peaks at two years of age and is the most common cause of conductive hearing loss and elective surgery in childhood. Treatment options include grommet insertion, which allows air to pass through into the middle ear, and adenoidectomy. However, grommets usually stop functioning after about ten months. It is important to understand the symptoms and risk factors of glue ear to seek appropriate treatment and prevent further complications.

Management of Benign Paroxysmal Positional Vertigo

This patient is exhibiting typical signs and symptoms of benign paroxysmal positional vertigo (BPPV). It is important to note that vestibular sedatives are not effective in managing BPPV. However, the Epley manoeuvre can be performed and taught to the patient, which has been shown to effectively reduce or eliminate symptoms.

It is also important to remember that no treatment needed is a valid management option for BPPV. This concept is particularly relevant for the MRCGP AKT exam, which tests primary care management skills. As a primary care physician, it is important to recognize when doing nothing is the most appropriate course of action for a patient. Don’t hesitate to select this option if it is the best choice for the patient’s condition.

Overall, the management of BPPV involves a combination of patient education, reassurance, and appropriate interventions such as the Epley manoeuvre.

If a child has significant hearing loss due to glue ear on two separate occasions, it is recommended to refer them to an ear, nose and throat (ENT) specialist. The current NICE CKS guidance suggests observing children with otitis media with effusion for 6-12 weeks as spontaneous resolution is common. However, if the signs and symptoms persist after this period, referral to an ENT specialist is necessary. It is important to inquire about any concerns regarding the child’s hearing or language development and for any complications. Immediate referral is required for children with Down’s syndrome or cleft palate who are suspected to have otitis media with effusion. Antibiotics are not recommended for the treatment of otitis media with effusion. The most common surgical option is myringotomy and insertion of grommets, but non-surgical management options are also considered by the ENT specialist. As the child in question has already presented with persistent hearing loss after 12 weeks, referral to ENT is appropriate at this point.

Understanding Glue Ear

Glue ear, also known as serous otitis media, is a common condition among children, with most experiencing at least one episode during their childhood. It is characterized by the accumulation of fluid in the middle ear, leading to hearing loss, speech and language delay, and behavioral or balance problems. The risk factors for glue ear include male sex, siblings with the condition, bottle feeding, day care attendance, and parental smoking. It is more prevalent during the winter and spring seasons.

The condition typically peaks at two years of age and is the most common cause of conductive hearing loss and elective surgery in childhood. Treatment options include grommet insertion, which allows air to pass through into the middle ear, and adenoidectomy. However, grommets usually stop functioning after about ten months. It is important to understand the symptoms and risk factors of glue ear to seek appropriate treatment and prevent further complications.

If rotatory nystagmus is observed during the Dix-Hallpike manoeuvre, it is likely that the patient has benign paroxysmal positional vertigo (BPPV). This is supported by the patient’s history of vertigo lasting less than 1 minute when changing head position. The Dix-Hallpike manoeuvre is the recommended examination by NICE to diagnose BPPV and can provoke rotatory upbeat nystagmus.

It is important to note that while the Dix-Hallpike manoeuvre is specific to BPPV, it produces rotatory nystagmus rather than vertical nystagmus. The Epley manoeuvre is used as a treatment for BPPV, not as a diagnostic tool.

Unterberger’s test is not used to diagnose BPPV, but rather to assess vertigo and examine for labyrinth dysfunction, which may be associated with hearing loss and tinnitus.

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo that occurs suddenly when there is a change in head position. It is more prevalent in individuals over the age of 55 and is less common in younger patients. Symptoms of BPPV include dizziness and vertigo, which can be accompanied by nausea. Each episode typically lasts for 10-20 seconds and can be triggered by rolling over in bed or looking upwards. A positive Dix-Hallpike manoeuvre, which is indicated by vertigo and rotatory nystagmus, can confirm the diagnosis of BPPV.

Fortunately, BPPV has a good prognosis and usually resolves on its own within a few weeks to months. Treatment options include the Epley manoeuvre, which is successful in around 80% of cases, and vestibular rehabilitation exercises such as the Brandt-Daroff exercises. While medication such as Betahistine may be prescribed, it tends to have limited effectiveness. However, it is important to note that around half of individuals with BPPV may experience a recurrence of symptoms 3-5 years after their initial diagnosis.

Understanding Vestibular Neuronitis

Vestibular neuronitis is a type of vertigo that typically occurs after a viral infection. It is characterized by recurrent episodes of vertigo that can last for hours or days, accompanied by nausea and vomiting. Horizontal nystagmus is also a common symptom, but there is no hearing loss or tinnitus.

It is important to differentiate vestibular neuronitis from other conditions such as viral labyrinthitis and posterior circulation stroke. The HiNTs exam can be used to distinguish between these conditions.

Treatment for vestibular neuronitis typically involves medication to alleviate symptoms, such as buccal or intramuscular prochlorperazine for severe cases, or a short course of oral medication for less severe cases. Vestibular rehabilitation exercises are also recommended for patients who experience chronic symptoms.

Understanding the symptoms and treatment options for vestibular neuronitis can help individuals manage this condition and improve their quality of life.

Common Oral Conditions and Their Symptoms

Geographic tongue is a common oral condition that presents with mild burning and irritation of the tongue. It is characterized by single or multiple well-demarcated irregular but smooth red plaques on the dorsum of the tongue. Stress and spicy food may exacerbate the condition.

Angular chelitis, on the other hand, presents with irritation of the corners of the lips and dryness. Aphthous stomatitis describes solitary or multiple painful ulcers on the mucosal membranes. Oral hairy leukoplakia is an asymptomatic white thickening and accentuation of the folds of the lateral margins of the tongue.

Lastly, acute necrotising ulcerative gingivitis presents with punched-out ulcers, necrosis, and bleeding of areas between teeth. It is important to be aware of these common oral conditions and their symptoms to seek appropriate management and treatment.

If topical antibiotics do not provide relief for otitis externa, it is recommended to refer the patient to an ear, nose, and throat (ENT) specialist. This is because the infection can cause swelling and narrowing of the ear canal, making it difficult for antibiotic drops to be effective. In such cases, microsuction and insertion of a pope wick may be necessary, which requires the expertise of an ENT specialist.

Ear syringing should not be performed during an active infection as it will not be helpful.

Steroids are often included in antibiotic ear drops, but they will not be effective if the drops cannot reach the ear canal.

Oral antibiotics, such as ciprofloxacin, may be prescribed alongside topical antibiotics if there is concern of a deep tissue infection. However, this is unlikely in a young and otherwise healthy patient, and the primary treatment remains antibiotic drops.

If necrotising otitis externa is suspected, a CT scan may be helpful, but this would be arranged by an ENT specialist and is not necessary in most cases.

Understanding Otitis Externa: Causes, Features, and Management

Otitis externa is a prevalent condition that often prompts primary care visits in the UK. It is characterized by ear pain, itch, and discharge, and can be caused by bacterial or fungal infections, seborrhoeic dermatitis, or contact dermatitis. Swimming is also a common trigger for otitis externa. Upon examination, the ear canal may appear red, swollen, or eczematous.

The recommended initial management for otitis externa is the use of topical antibiotics or a combination of topical antibiotics with a steroid. However, if the tympanic membrane is perforated, aminoglycosides are traditionally not used. If there is canal debris, removal may be necessary, and if the canal is extensively swollen, an ear wick may be inserted. Second-line options include taking a swab inside the ear canal, considering contact dermatitis secondary to neomycin, or using oral antibiotics such as flucloxacillin if the infection is spreading. Empirical use of an antifungal agent may also be considered.

It is important to note that if a patient fails to respond to topical antibiotics, they should be referred to an ENT specialist. Malignant otitis externa is a more severe form of the condition that is more common in elderly diabetics. It involves the extension of infection into the bony ear canal and the soft tissues deep to the bony canal, and may require intravenous antibiotics. While some ENT doctors disagree, concerns about ototoxicity may arise with the use of aminoglycosides in patients with perforated tympanic membranes.

Patients with suspected temporomandibular joint dysfunction should be encouraged to practice early self-management techniques to control their symptoms and limit functional impairment. These techniques include using simple analgesics like paracetamol or ibuprofen, applying heat packs to the affected area, and avoiding hard or crunchy foods that can exacerbate the pain. With proper self-management, patients can expect to recover within 2-3 months.

If temporal arteritis is suspected, investigations such as ESR and temporal biopsy may be necessary. This condition presents with a throbbing headache, an obvious temporal artery, and claudication when chewing, and requires immediate treatment with corticosteroids to prevent vision loss.

While referral to a dentist may be necessary if self-management techniques are ineffective, an x-ray of the mandible is not required for diagnosis. Strong analgesia and opioids should be avoided, as simple analgesia is just as effective and carries fewer risks. X-rays are also unnecessary, as TMJ dysfunction is a clinical diagnosis that doesn’t require imaging to manage.

Understanding Temporomandibular Joint Dysfunction

Temporomandibular joint dysfunction (TMJ) is a condition that affects the jaw joint and the muscles that control its movement. It is characterized by pain in the TMJ area, which may radiate to the head, neck, or ear. Patients may also experience restricted jaw motion, making it painful to chew or speak. Additionally, they may notice clicking or other noises when moving their jaw.

To manage TMJ, healthcare professionals may recommend soft foods to reduce the strain on the jaw. Simple analgesia, such as paracetamol and NSAIDs, can also help alleviate pain. Short courses of benzodiazepines may be prescribed to help relax the muscles and reduce anxiety. It is also important to seek a review by a dentist to rule out any dental issues that may be contributing to the condition.

In summary, TMJ is a painful condition that affects the jaw joint and muscles. It can be managed through a combination of lifestyle changes, medication, and dental care. By understanding the symptoms and seeking appropriate treatment, patients can improve their quality of life and reduce the impact of TMJ on their daily activities.

Severe pain in a patient with Bell’s palsy may be a sign of Ramsay Hunt syndrome, which is caused by herpes zoster and is accompanied by a painful rash and herpetic vesicles. Urgent referral to ENT is necessary if the facial paralysis has not improved after one month. Loss of taste in the anterior two-thirds of the tongue on the same side as the facial weakness may occur but doesn’t require urgent referral. Referral to a plastic surgeon with expertise in facial reconstructive surgery should be considered if there is residual paralysis after 6-9 months. Corticosteroid treatment is recommended as it has been shown to improve prognosis based on evidence from meta-analyses, while antiviral treatments are not recommended alone or in combination with prednisolone.

Bell’s palsy is a sudden, one-sided facial nerve paralysis of unknown cause. It typically affects individuals between the ages of 20 and 40, and is more common in pregnant women. The condition is characterized by a lower motor neuron facial nerve palsy that affects the forehead, while sparing the upper face. Patients may also experience post-auricular pain, altered taste, dry eyes, and hyperacusis.

The management of Bell’s palsy has been a topic of debate, with various treatment options proposed in the past. However, there is now consensus that all patients should receive oral prednisolone within 72 hours of onset. The addition of antiviral medications is still a matter of discussion, with some experts recommending it for severe cases. Eye care is also crucial to prevent exposure keratopathy, and patients may need to use artificial tears and eye lubricants. If they are unable to close their eye at bedtime, they should tape it closed using microporous tape.

Follow-up is essential for patients who show no improvement after three weeks, as they may require urgent referral to ENT. Those with more long-standing weakness may benefit from a referral to plastic surgery. The prognosis for Bell’s palsy is generally good, with most patients making a full recovery within three to four months. However, untreated cases can result in permanent moderate to severe weakness in around 15% of patients.

Meniere’s disease is a condition that affects the inner ear and its cause is unknown. It is more commonly seen in middle-aged adults but can occur at any age and affects both men and women equally. The condition is characterized by the excessive pressure and progressive dilation of the endolymphatic system. The main symptoms of Meniere’s disease are recurrent episodes of vertigo, tinnitus, and sensorineural hearing loss. Vertigo is usually the most prominent symptom, but patients may also experience a sensation of aural fullness or pressure, nystagmus, and a positive Romberg test. These episodes can last from minutes to hours and are typically unilateral, but bilateral symptoms may develop over time.

The natural history of Meniere’s disease is that symptoms usually resolve in the majority of patients after 5-10 years. However, most patients will be left with some degree of hearing loss, and psychological distress is common. ENT assessment is required to confirm the diagnosis, and patients should inform the DVLA as the current advice is to cease driving until satisfactory control of symptoms is achieved. Acute attacks can be managed with buccal or intramuscular prochlorperazine, and admission to the hospital may be required. Prevention strategies include the use of betahistine and vestibular rehabilitation exercises, which may be beneficial.

If Rinne’s test is negative, it indicates that bone conduction is greater than air conduction, resulting in a conductive hearing loss in the affected ear. A positive test is considered normal when air conduction is greater than bone conduction. Therefore, the diagnosis of left-sided conductive hearing loss is correct, and Weber’s test would localize to the affected side in unilateral conductive hearing loss.

Left-sided mixed hearing loss is an incorrect diagnosis because Weber’s test would localize to the right, and on an audiogram, mixed hearing loss would show both bone and air conduction at abnormal levels (>20 dB) with a difference of at least >15 dB between them.

Left-sided sensorineural hearing loss is also an incorrect diagnosis because Weber’s test would localize to the right, and Rinne’s test would be positive in the left ear.

Right-sided conductive hearing loss is an incorrect diagnosis because a positive Rinne’s test indicates that air conduction is greater than bone conduction, which is considered normal.

Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness

Rinne’s and Weber’s tests are used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus.

Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, with the sound lateralizing to the unaffected ear.

Overall, Rinne’s and Weber’s tests are useful tools for differentiating between conductive and sensorineural deafness, allowing for appropriate management and treatment.

Understanding Kawasaki Disease

Kawasaki disease is a leading cause of acquired heart disease in children in the UK. Although its prevalence is low, the risk of complications is high due to late diagnosis. As such, it is important to have a good understanding of the disease, which may be tested in the AKT exam.

The exact cause of Kawasaki disease is unknown, but it is believed to be due to a microbiological toxin. If left untreated, it can lead to coronary aneurysms. To diagnose Kawasaki disease, consider it in children with fever lasting over five days and who have four of the following five features: bilateral conjunctival injection, change in mucous membranes in the upper respiratory tract, change in the extremities, polymorphous rash, or cervical lymphadenopathy. In rare cases, incomplete or atypical Kawasaki disease may be diagnosed with fewer features.

To help remember the features of Kawasaki disease, think All Red + Cervical Lymphadenopathy. This stands for red eyes, red mouth, red rash, red hands, and cervical lymphadenopathy. By being aware of these symptoms, healthcare professionals can diagnose and treat Kawasaki disease promptly, reducing the risk of complications.

Referral to ENT is urgently needed for a patient experiencing recurrent Bell’s palsy. Treatment with corticosteroids is recommended for Bell’s palsy, as it has been shown to improve prognosis in meta-analyses. Antiviral treatments are not recommended. Loss of taste in the anterior two-thirds of the tongue on the same side as the facial weakness may occur with Bell’s palsy, but doesn’t require urgent referral to ENT. It is important to note that a bilateral palsy is not a Bell’s palsy and requires urgent referral to ENT or neurology.

Bell’s palsy is a sudden, one-sided facial nerve paralysis of unknown cause. It typically affects individuals between the ages of 20 and 40, and is more common in pregnant women. The condition is characterized by a lower motor neuron facial nerve palsy that affects the forehead, while sparing the upper face. Patients may also experience post-auricular pain, altered taste, dry eyes, and hyperacusis.

The management of Bell’s palsy has been a topic of debate, with various treatment options proposed in the past.

If they are unable to close their eye at bedtime, they should tape it closed using microporous tape.

Follow-up is essential for patients who show no improvement after three weeks, as they may require urgent referral to ENT. Those with more long-standing weakness may benefit from a referral to plastic surgery. The prognosis for Bell’s palsy is generally good, with most patients making a full recovery within three to four months. However, untreated cases can result in permanent moderate to severe weakness in around 15% of patients.

Idiopathic Unilateral Sudden Sensorineural Hearing Loss: Causes, Symptoms, and Treatment Options

Idiopathic unilateral sudden sensorineural hearing loss (ISSHL) is a rare condition characterized by a sudden loss of hearing in one ear, often accompanied by tinnitus, vertigo, and aural fullness. The exact cause of ISSHL is not well understood, but it may be linked to viral infections, vascular issues, or immune-mediated inner ear disease.

Patients with ISSHL should be referred for urgent treatment, typically involving corticosteroids. Other treatment options include low molecular weight dextran, carbogen, hyperbaric oxygen, low-density lipid apheresis, aciclovir, and stellate ganglion block. However, there is limited evidence to support the effectiveness of any one treatment.

Many patients with ISSHL are admitted to the hospital, but fortunately, spontaneous recovery rates are generally good. Studies have reported recovery rates ranging from 47-63%, although different criteria for recovery were used in each study.

In summary, ISSHL is a rare but serious condition that requires prompt medical attention. While treatment options exist, the evidence for their effectiveness is limited, and many patients may recover spontaneously.

Patterns of Hearing Loss Revealed by Pure Tone Audiometry

Pure tone audiometry is a valuable tool for identifying patterns of hearing loss. A normal individual will have hearing thresholds above 20 dBHL across all frequencies. Meniere’s disease typically shows hearing loss at lower frequencies, while presbyacusis often presents with high frequency loss in a ‘ski slope’ pattern.

Early noise-induced hearing loss (NIHL) is usually characterized by a notch between 3 and 6 kHz, with recovery at higher frequencies. If presbyacusis is also present, the notch may be less prominent and appear more like a ‘bulge.’ NIHL is typically bilateral, but it can occur unilaterally in activities such as shooting. As NIHL progresses, the notch seen in early disease may disappear, and there may be increasing hearing loss at all frequencies, most notably at higher frequencies, which can sometimes be difficult to differentiate from presbyacusis.

In summary, pure tone audiometry can reveal various patterns of hearing loss, which can aid in the diagnosis and management of different types of hearing disorders.

Understanding Cholesteatoma

Cholesteatoma is a benign growth of squamous epithelium that can cause damage to the skull base. It is most commonly found in individuals between the ages of 10 and 20 years old. Those born with a cleft palate are at a higher risk of developing cholesteatoma, with a 100-fold increase in risk.

The main symptoms of cholesteatoma include a persistent discharge with a foul odor and hearing loss. Other symptoms may occur depending on the extent of the growth, such as vertigo, facial nerve palsy, and cerebellopontine angle syndrome.

During otoscopy, a characteristic attic crust may be seen in the uppermost part of the eardrum.

Management of cholesteatoma involves referral to an ear, nose, and throat specialist for surgical removal. Early detection and treatment are important to prevent further damage to the skull base and surrounding structures.

In summary, cholesteatoma is a non-cancerous growth that can cause significant damage if left untreated. It is important to be aware of the symptoms and seek medical attention promptly if they occur.

Treatment Options for earwax: Ear Drops, Microsuction, and Manual Removal

earwax, also known as cerumen, can cause discomfort and hearing problems if it builds up in the ear canal. The first-line treatment for earwax is ear drops, which can soften the wax and make it easier to remove. Microsuction is a safer alternative to irrigation, but it is not widely available. Manual removal using a probe is also an option. However, there is little evidence on the effectiveness of these treatments.

Various types of ear drops can be used, including sodium bicarbonate, sodium chloride, olive oil, and almond oil. Cerumol® is a commonly used proprietary agent. However, the British National Formulary warns against using docusate sodium (Waxsol®, Molcer®) or urea hydrogen peroxide (Exterol®, Otex®) as they may irritate the external meatus.

Regardless of the type of ear drop used, the patient should lie with the affected ear uppermost for 5-10 minutes after applying the drops. While using any type of ear drop appears to be better than no treatment, it is uncertain if one type of drop is more effective than another. Therefore, it is important to seek advice from a healthcare professional before attempting to remove earwax at home.

Alcohol consumption is linked to 30% of cases in the UK.

When to Refer Patients with Mouth Lesions for Oral Surgery

Mouth lesions can be a cause for concern, especially if they persist for an extended period of time. In cases where there is unexplained oral ulceration or mass that lasts for more than three weeks, or red and white patches that are painful, swollen, or bleeding, a referral to oral surgery should be made within two weeks. Additionally, if a patient experiences one-sided pain in the head and neck area for more than four weeks, which is associated with earache but doesn’t result in any abnormal findings on otoscopy, or has an unexplained recent neck lump or a previously undiagnosed lump that has changed over a period of three to six weeks, a referral should be made.

Patients who have persistent sore or painful throats or signs and symptoms in the oral cavity that last for more than six weeks and cannot be definitively diagnosed as a benign lesion should also be referred. It is important to note that the level of suspicion should be higher in patients who are over 40, smokers, heavy drinkers, and those who chew tobacco or betel nut (areca nut). By following these guidelines, healthcare professionals can ensure that patients with mouth lesions receive timely and appropriate care.

Understanding Allergic Rhinitis

Allergic rhinitis is a condition that causes inflammation in the nose due to sensitivity to allergens such as dust mites, grass, tree, and weed pollens. It can be classified into seasonal, perennial, or occupational, depending on the timing and cause of symptoms. Seasonal rhinitis, which occurs due to pollens, is commonly known as hay fever. Symptoms of allergic rhinitis include sneezing, bilateral nasal obstruction, clear nasal discharge, post-nasal drip, and nasal pruritus.

The management of allergic rhinitis involves allergen avoidance and medication. For mild-to-moderate intermittent or mild persistent symptoms, oral or intranasal antihistamines may be prescribed. For moderate-to-severe persistent symptoms or if initial drug treatment is ineffective, intranasal corticosteroids may be recommended. In some cases, a short course of oral corticosteroids may be necessary to cover important life events. Topical nasal decongestants, such as oxymetazoline, may also be used for short periods, but prolonged use can lead to tachyphylaxis and rebound hypertrophy of the nasal mucosa (rhinitis medicamentosa) upon withdrawal.

In summary, allergic rhinitis is a common condition that can cause discomfort and affect daily life. Understanding the different types of allergic rhinitis and its symptoms can help in managing the condition effectively. It is important to consult a healthcare professional for proper diagnosis and treatment.

When a patient experiences progressive dysphagia and weight loss, it is important to investigate for possible oesophageal carcinoma as these are common symptoms. Laryngeal nerve damage can also cause hoarseness in patients with this type of cancer. While achalasia may present with similar symptoms, patients typically have difficulty swallowing both solids and liquids equally, and may experience intermittent regurgitation of food. On the other hand, oesophageal spasm is characterized by pain during swallowing.

Oesophageal Cancer: Types, Risk Factors, Features, Diagnosis, and Treatment

Oesophageal cancer used to be mostly squamous cell carcinoma, but adenocarcinoma is now becoming more common, especially in patients with a history of gastro-oesophageal reflux disease (GORD) or Barrett’s. Adenocarcinoma is usually located near the gastroesophageal junction, while squamous cell tumours are found in the upper two-thirds of the oesophagus. The most common presenting symptom is dysphagia, followed by anorexia and weight loss, vomiting, and other possible features such as odynophagia, hoarseness, melaena, and cough.

To diagnose oesophageal cancer, upper GI endoscopy with biopsy is used, and endoscopic ultrasound is preferred for locoregional staging. CT scanning of the chest, abdomen, and pelvis is used for initial staging, and FDG-PET CT may be used for detecting occult metastases if metastases are not seen on the initial staging CT scans. Laparoscopy is sometimes performed to detect occult peritoneal disease.

Operable disease is best managed by surgical resection, with the most common procedure being an Ivor-Lewis type oesophagectomy. However, the biggest surgical challenge is anastomotic leak, which can result in mediastinitis. In addition to surgical resection, many patients will be treated with adjuvant chemotherapy.

Differentiating Types of Hearing Loss: A Case Study

In this case study, the patient presents with hearing loss in their right ear. To determine the type of hearing loss, various tests were conducted.

Right-sided conductive hearing loss was ruled out as bone conduction was better than air conduction in the affected ear. Left-sided conductive hearing loss was also ruled out as Rinne’s test was normal on the left side.

Non-organic hearing loss was considered but ultimately ruled out as the patient’s history was convincing and their tympanic membrane appeared normal.

Left-sided sensorineural hearing loss and right-sided sensorineural hearing loss were both ruled out as they would have caused a reduction in both air and bone conduction.

The final diagnosis was right-sided conductive hearing loss. It is important to differentiate between the types of hearing loss as treatment options vary depending on the cause.

Patients with peripheral vertigo may experience distressing symptoms, such as those caused by vestibular neuronitis and labyrinthitis. To alleviate these symptoms in the short term, a sedating antihistamine like prochlorperazine can be prescribed for up to one week. However, longer courses of treatment may delay vestibular compensation and hinder recovery.

Haloperidol, which has a low affinity for histamine receptors, may not be effective in treating vertigo and could cause unwanted side effects. Cetirizine, a non-sedating antihistamine, would not address the nausea or vertigo symptoms. Betahistine, a histamine analogue, is only licensed for treating vertigo, tinnitus, and hearing loss associated with Meniere’s disease. While it may be considered for persistent symptoms, it is an unlicensed use and not recommended by NICE guidance.

Vertigo is a condition characterized by a false sensation of movement in the body or environment. There are various causes of vertigo, each with its own unique characteristics. Viral labyrinthitis, for example, is typically associated with a recent viral infection, sudden onset, nausea and vomiting, and possible hearing loss. Vestibular neuronitis, on the other hand, is characterized by recurrent vertigo attacks lasting hours or days, but with no hearing loss. Benign paroxysmal positional vertigo is triggered by changes in head position and lasts for only a few seconds. Meniere’s disease, meanwhile, is associated with hearing loss, tinnitus, and a feeling of fullness or pressure in the ears. Elderly patients with vertigo may be experiencing vertebrobasilar ischaemia, which is accompanied by dizziness upon neck extension. Acoustic neuroma, which is associated with hearing loss, vertigo, and tinnitus, is also a possible cause of vertigo. Other causes include posterior circulation stroke, trauma, multiple sclerosis, and ototoxicity from medications like gentamicin.

The NICE guidelines advise referring patients with recurrent epistaxis and a high risk of underlying disorders to ear, nose and throat for investigation. This patient, who is of Chinese origin and has recurrent nosebleeds, nasal obstruction, and weight loss, is at high risk of nasopharyngeal cancer due to his ethnicity and age. The full blood count results show thrombocytosis, which may indicate malignancy. Hereditary telangiectasia and Von Willebrand’s disease are unlikely due to the absence of a family history and the onset of nosebleeds in later life. Nasal polyps do not typically cause epistaxis, but may present with nasal obstruction, postnasal drip, snoring, or obstructive sleep apnoea. The patient’s age rules out angiofibroma as a possible cause, as this benign tumour typically occurs in pre-pubescent and adolescent males and is rare over the age of 25.

Understanding Nasopharyngeal Carcinoma

Nasopharyngeal carcinoma is a type of squamous cell carcinoma that affects the nasopharynx. It is a rare form of cancer that is more common in individuals from Southern China and is associated with Epstein Barr virus infection. The presenting features of nasopharyngeal carcinoma include cervical lymphadenopathy, otalgia, unilateral serous otitis media, nasal obstruction, discharge, and/or epistaxis, and cranial nerve palsies such as III-VI.

To diagnose nasopharyngeal carcinoma, a combined CT and MRI scan is typically used. The first line of treatment for this type of cancer is radiotherapy. It is important to catch nasopharyngeal carcinoma early to increase the chances of successful treatment.

Differentiating between tympanic membrane perforation and sensorineural hearing loss due to skull trauma is crucial. Rinne’s test can help identify conductive hearing loss in the affected ear, while Weber’s test can rule out sensorineural hearing loss on the right.

Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness

Rinne’s and Weber’s tests are used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus. A positive test indicates that air conduction (AC) is better than bone conduction (BC), while a negative test indicates that BC is better than AC, suggesting conductive deafness.

Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking the patient which side is loudest. In unilateral sensorineural deafness, sound is localized to the unaffected side, while in unilateral conductive deafness, sound is localized to the affected side.

The table below summarizes the interpretation of Rinne and Weber tests. A normal result indicates that AC is greater than BC bilaterally and the sound is midline. Conductive hearing loss is indicated by BC being greater than AC in the affected ear and AC being greater than BC in the unaffected ear, with the sound lateralizing to the affected ear. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, with the sound lateralizing to the unaffected ear.

Overall, Rinne’s and Weber’s tests are useful tools for differentiating between conductive and sensorineural deafness, allowing for appropriate management and treatment.

The patient is exhibiting signs of systemic disturbance and requires antibiotic treatment. A 7 to 10-day antibiotic regimen is recommended to effectively eliminate any potential Streptococcus infection. The BNF recommends Phenoxymethylpenicillin as the primary antibiotic option.

Management of Sore Throat

Sore throat is a common condition that includes pharyngitis, tonsillitis, and laryngitis. Routine throat swabs and rapid antigen tests are not recommended for patients with a sore throat. Pain relief can be achieved with paracetamol or ibuprofen, and antibiotics are not usually necessary. However, antibiotics may be indicated for patients with marked systemic upset, unilateral peritonsillitis, a history of rheumatic fever, an increased risk from acute infection, or when 3 or more Centor criteria are present. The Centor criteria and FeverPAIN criteria can be used to determine the likelihood of isolating Streptococci. If antibiotics are necessary, phenoxymethylpenicillin or clarithromycin can be given for a 7 or 10 day course. There is some evidence that a single dose of oral corticosteroid may reduce the severity and duration of pain, but this has not yet been incorporated into UK guidelines.

If there is no hearing loss, it is more likely that the patient has vestibular neuronitis rather than viral labyrinthitis.

Understanding Vestibular Neuronitis

Vestibular neuronitis is a type of vertigo that typically occurs after a viral infection. It is characterized by recurrent episodes of vertigo that can last for hours or days, accompanied by nausea and vomiting. Horizontal nystagmus is also a common symptom, but there is no hearing loss or tinnitus.

It is important to differentiate vestibular neuronitis from other conditions such as viral labyrinthitis and posterior circulation stroke. The HiNTs exam can be used to distinguish between these conditions.

Treatment for vestibular neuronitis typically involves medication to alleviate symptoms, such as buccal or intramuscular prochlorperazine for severe cases, or a short course of oral medication for less severe cases. Vestibular rehabilitation exercises are also recommended for patients who experience chronic symptoms.

Understanding the symptoms and treatment options for vestibular neuronitis can help individuals manage this condition and improve their quality of life.

Unilateral symptoms should raise concern for patients with chronic rhinosinusitis. The typical presentation includes facial pain, frontal pressure worsened by bending forward, clear nasal discharge (if due to allergies), and difficulty breathing through the nose. Post-nasal drip may also cause a chronic cough. However, if the symptoms are only on one side, it is considered a red flag and warrants a referral to an ENT specialist. The standard management for chronic sinusitis involves avoiding allergens, using intranasal corticosteroids, and irrigating the nasal passages with saline solution. Loratadine may be helpful if the cause is related to allergies.

Understanding Chronic Rhinosinusitis

Chronic rhinosinusitis is a common condition that affects approximately 10% of the population. It is characterized by inflammation of the nasal passages and paranasal sinuses that lasts for 12 weeks or more. There are several factors that can predispose individuals to this condition, including atopy, nasal obstruction, recent infections, swimming/diving, and smoking.

Symptoms of chronic rhinosinusitis include facial pain, nasal discharge, nasal obstruction, and post-nasal drip. Treatment options include avoiding allergens, using intranasal corticosteroids, and nasal irrigation with saline solution. However, it is important to be aware of red flag symptoms such as unilateral symptoms, persistent symptoms despite treatment, and epistaxis, which may require further evaluation and management.

In summary, chronic rhinosinusitis is a common inflammatory disorder that can cause significant discomfort and impact quality of life. Understanding the predisposing factors and symptoms, as well as appropriate management strategies, can help individuals effectively manage this condition.

When to Admit a Patient with a Sore Throat: Indications and Recommendations

Admission to the hospital for a sore throat is necessary in certain cases. One such case is when the patient cannot swallow, making oral treatments ineffective. A Paul-Bunnell test may be considered, but it is not the first-line management. An ultrasound scan is only necessary for unexplained cervical lymphadenopathy.

According to NICE, hospital admission is recommended for sore throat cases that are immediately life-threatening, such as acute epiglottitis or Kawasaki disease. Other indications include dehydration or reluctance to take fluids, suppurative complications like quinsy, immunosuppression, and signs of being markedly systemically unwell.

It is important to be aware of these indications and recommendations to ensure proper management and treatment of sore throat cases.

Immediate investigation is necessary for any oral cavity lesion that appears suspicious for erythroplakia or leukoplakia due to the risk of malignancy.

When to Refer Patients with Mouth Lesions for Oral Surgery

Mouth lesions can be a cause for concern, especially if they persist for an extended period of time. In cases where there is unexplained oral ulceration or mass that lasts for more than three weeks, or red and white patches that are painful, swollen, or bleeding, a referral to oral surgery should be made within two weeks. Additionally, if a patient experiences one-sided pain in the head and neck area for more than four weeks, which is associated with earache but doesn’t result in any abnormal findings on otoscopy, or has an unexplained recent neck lump or a previously undiagnosed lump that has changed over a period of three to six weeks, a referral should be made.

Patients who have persistent sore or painful throats or signs and symptoms in the oral cavity that last for more than six weeks and cannot be definitively diagnosed as a benign lesion should also be referred. It is important to note that the level of suspicion should be higher in patients who are over 40, smokers, heavy drinkers, and those who chew tobacco or betel nut (areca nut). By following these guidelines, healthcare professionals can ensure that patients with mouth lesions receive timely and appropriate care. For more information on this topic, please refer to the link provided.

If an oral ulcer persists for more than 3 weeks without explanation, it is important to refer the patient to secondary care urgently to rule out the possibility of malignancy. While smoking is a risk factor for both oral malignancy and aphthous ulcers, it is not a reason for referral. Interestingly, quitting smoking can actually make aphthous ulcers worse. Over-the-counter local analgesics like Difflam (benzydamine hydrochloride) and Bonjela can provide relief from symptoms, but there is no evidence that they can reduce the frequency or duration of ulceration. Some evidence suggests that antibacterial mouthwashes (such as chlorhexidine) and topical corticosteroids (such as hydrocortisone oromucosal tablets) can help to shorten the duration and severity of symptoms, but they do not reduce the frequency of recurrence.

Aphthous mouth ulcers are painful sores that are circular or oval in shape and are found only in the mouth. They are not associated with any systemic disease and often occur repeatedly, usually starting in childhood. These ulcers can be caused by damage to the mouth, such as biting the cheek or brushing too hard, or may be due to a genetic predisposition. Other factors that can trigger these ulcers include stress, certain foods, stopping smoking, and hormonal changes related to the menstrual cycle.

Aphthous ulcers are characterized by their round or oval shape, a clearly defined margin, a yellowish-grey slough on the floor, and a red periphery. They usually appear on non-keratinized mucosal surfaces, such as the inside of the lips, cheeks, floor of the mouth, or undersurface of the tongue. In most cases, investigations are not necessary, but they may be considered if an underlying systemic disease is suspected.

Treatment for aphthous ulcers involves avoiding any factors that may trigger them and providing symptomatic relief for pain, discomfort, and swelling. This may include using a low potency topical corticosteroid, an antimicrobial mouthwash, or a topical analgesic. Most ulcers will heal within two weeks without leaving any scars. However, if a mouth ulcer persists for more than three weeks, it is important to seek urgent referral to a specialist.

When standard treatment fails to control allergic rhinitis, it may be necessary to use short courses of steroids to manage important life events. However, it is important to note that oral steroids should only be used for a brief period if the symptoms are severe and significantly impacting the person’s quality of life. There is no evidence to suggest that switching to a different steroid nasal spray would be more effective. Chlorphenamine, a sedating antihistamine, would not be suitable in this situation. Intramuscular steroids are not recommended due to the risk of avascular necrosis from repeated doses. While immunotherapy may be an option in the long term, it will not provide immediate relief in time for a significant event such as a wedding.

Understanding Allergic Rhinitis

Allergic rhinitis is a condition that causes inflammation in the nose due to sensitivity to allergens such as dust mites, grass, tree, and weed pollens. It can be classified into seasonal, perennial, or occupational, depending on the timing and cause of symptoms. Seasonal rhinitis, which occurs due to pollens, is commonly known as hay fever. Symptoms of allergic rhinitis include sneezing, bilateral nasal obstruction, clear nasal discharge, post-nasal drip, and nasal pruritus.

The management of allergic rhinitis involves allergen avoidance and medication. For mild-to-moderate intermittent or mild persistent symptoms, oral or intranasal antihistamines may be prescribed. For moderate-to-severe persistent symptoms or if initial drug treatment is ineffective, intranasal corticosteroids may be recommended. In some cases, a short course of oral corticosteroids may be necessary to cover important life events. Topical nasal decongestants, such as oxymetazoline, may also be used for short periods, but prolonged use can lead to tachyphylaxis and rebound hypertrophy of the nasal mucosa (rhinitis medicamentosa) upon withdrawal.

In summary, allergic rhinitis is a common condition that can cause discomfort and affect daily life. Understanding the different types of allergic rhinitis and its symptoms can help in managing the condition effectively. It is important to consult a healthcare professional for proper diagnosis and treatment.

Causes of Gum Hypertrophy

Gum hypertrophy, or an abnormal increase in the size of the gums, can be caused by various factors. One of the common causes is the use of certain drugs such as phenytoin, which is used to treat seizures. Acute myeloid leukaemias can also lead to gum hypertrophy.

Scurvy, a condition caused by vitamin C deficiency, can result in swollen and bleeding gums, but it is not typically associated with true gingival hypertrophy. Instead, petechiae, or small red or purple spots, may appear on the mucosae.

Lead toxicity can cause pigmentation of the gums, while carbamazepine, a medication used to treat seizures and bipolar disorder, is not typically associated with gum hypertrophy. However, it can cause other side effects such as ataxia, drowsiness, and blood dyscrasias.

In summary, while gum hypertrophy can be caused by various factors, phenytoin and acute myeloid leukaemias are the most likely culprits. Scurvy may cause swollen and bleeding gums, but it is not typically associated with true gingival hypertrophy. Lead toxicity can cause pigmentation of the gums, while carbamazepine is not typically associated with gum hypertrophy.

Treatment Guidelines for Allergic and Non-Allergic Rhinitis

Guidelines for the treatment of allergic and non-allergic rhinitis recommend the use of oral non-sedating antihistamines, topical nasal corticosteroids or antihistamines, and anti-inflammatory eye drops either in isolation or in combination. For mild symptoms, oral and/or topical antihistamines are recommended, with regular use being more effective than as-required use. Sedating antihistamines should be avoided due to their negative effects on academic and work performance.

In moderate to severe symptoms, intranasal corticosteroids are the treatment of choice if antihistamine treatment has been ineffective. Different preparations have different degrees of systemic absorption, with mometasone and fluticasone having negligible systemic absorption. Intranasal corticosteroids have an onset of action of six to eight hours after the first dose, but regular use for at least two weeks may be needed to see the maximal effects.

If treatment with the above doesn’t improve things, it is important to review technique and compliance and increase the dosage where appropriate. Short courses of oral corticosteroids may be used to gain control in severe nasal blockage or if the patient has a very important upcoming event. They should be used in conjunction with intranasal corticosteroids, and a burst of prednisolone at a dose of 0.5 mg/kg/day for 5-10 days can be used.

In addition to the above, watery rhinorrhoea may respond to topical ipratropium, and catarrh in those with co-existent asthma may be helped by a leukotriene receptor antagonist. These guidelines provide a comprehensive approach to the treatment of allergic and non-allergic rhinitis, with a range of options available depending on the severity of symptoms.

Consider vestibular migraine as a possible cause of episodic vertigo in patients with a history of migraines. The timing and duration of vertigo symptoms can help differentiate between different causes. Benign paroxysmal positional vertigo typically causes brief episodes of vertigo, while Meniere’s disease causes longer episodes with accompanying hearing loss, tinnitus, or ear fullness. Labyrinthitis and vestibular neuronitis can cause sudden onset of constant vertigo, but not the episodic nature described in this case. Given the duration, episodic nature, phonophobia, and history of migraines, vestibular migraine is the most likely diagnosis. The International Classification of Headache Disorders provides diagnostic criteria for vestibular migraine, including a history of migraines and moderate to severe vestibular symptoms lasting between 5 minutes and 72 hours, with at least half of the episodes associated with migrainous features such as headache, photophobia, phonophobia, or visual aura. Other potential causes should be ruled out.

Vertigo is a condition characterized by a false sensation of movement in the body or environment. There are various causes of vertigo, each with its own unique characteristics. Viral labyrinthitis, for example, is typically associated with a recent viral infection, sudden onset, nausea and vomiting, and possible hearing loss. Vestibular neuronitis, on the other hand, is characterized by recurrent vertigo attacks lasting hours or days, but with no hearing loss. Benign paroxysmal positional vertigo is triggered by changes in head position and lasts for only a few seconds. Meniere’s disease, meanwhile, is associated with hearing loss, tinnitus, and a feeling of fullness or pressure in the ears. Elderly patients with vertigo may be experiencing vertebrobasilar ischaemia, which is accompanied by dizziness upon neck extension. Acoustic neuroma, which is associated with hearing loss, vertigo, and tinnitus, is also a possible cause of vertigo. Other causes include posterior circulation stroke, trauma, multiple sclerosis, and ototoxicity from medications like gentamicin.

Management of an Immunocompromised Patient with Signs of Infection

In managing an immunocompromised patient with signs of infection, it is important to consider the potential risk of deterioration related to the infection. According to NICE guidelines, the most appropriate approach would be to start appropriate treatment and arrange a review appointment in 3 days. This allows for monitoring of treatment response and early detection of any potential complications.

If the patient doesn’t respond to treatment, immediate referral to an ENT specialist is necessary. Therefore, it is crucial to closely monitor the patient’s condition and ensure prompt action is taken if necessary. By following these guidelines, healthcare professionals can effectively manage immunocompromised patients with signs of infection and minimize the risk of complications.

If a patient has unilateral ear discharge and a facial nerve palsy on the left side, it is more likely to be a case of malignant otitis externa. This is a serious condition where the infection has spread to the temporal bone and can affect the facial nerve. The pain associated with this condition is severe and persistent, often waking the patient at night. Malignant otitis externa can be life-threatening in severe cases, and immediate referral to an ENT specialist for intravenous antibiotics and imaging is necessary.

Malignant Otitis Externa: A Rare but Serious Infection

Malignant otitis externa is a type of ear infection that is uncommon but can be serious. It is typically found in individuals who are immunocompromised, with 90% of cases occurring in diabetics. The infection starts in the soft tissues of the external auditory meatus and can progress to involve the soft tissues and bony ear canal, eventually leading to temporal bone osteomyelitis.

Key features in the patient’s history include diabetes or immunosuppression, severe and persistent ear pain, temporal headaches, and purulent otorrhea. In some cases, patients may also experience dysphagia, hoarseness, and facial nerve dysfunction.

Diagnosis is typically done through a CT scan, and non-resolving otitis externa with worsening pain should be referred urgently to an ENT specialist. Treatment involves intravenous antibiotics that cover pseudomonal infections.

In summary, malignant otitis externa is a rare but serious infection that requires prompt diagnosis and treatment. Patients with diabetes or immunosuppression should be particularly vigilant for symptoms and seek medical attention if they experience persistent ear pain or other related symptoms.

Treatment Options for Chronic Gingivitis

Chronic gingivitis is a common condition that can lead to gum inflammation, bleeding, and discomfort. Here are some treatment options for patients with chronic gingivitis:

1. Go to a general dental practitioner: Regular oral hygiene advice and treatment from a general dental practitioner can help manage chronic gingivitis.

2. Avoid prescribing antibiotics: Antibiotics are not indicated for chronic gingivitis, and their overuse can lead to antibiotic resistance.

3. Avoid prescribing mouthwash: While mouthwash can help prevent plaque and gingivitis, it is not effective for established plaque and cannot stop periodontitis from progressing.

4. Consider temporary pain relief: Saline mouthwash can provide temporary pain and swelling relief.

5. Prescribe metronidazole for acute necrotising ulcerative gingivitis: If the patient has punched-out gingival ulcers covered with a white, yellowish, or grey pseudomembrane, metronidazole 400 mg three times daily for one week may be necessary.

6. Refer to oral surgery for severe symptoms or suspicion of malignancy: Referral to oral surgery would only be necessary for severe or rapidly progressive symptoms or suspicion of malignancy.

By following these treatment options, patients with chronic gingivitis can manage their symptoms and improve their oral health.

Stertorous refers to a noisy and laboured breathing sound, often heard during deep sleep or coma, caused by obstruction in the upper airways. Hypernasal speech is an abnormal voice resonance due to increased airflow through the nose during speech, caused by an incomplete closure of the soft palate and/or velopharyngeal sphincter. Rales, also known as crackles or crepitations, are clicking or crackling noises heard during auscultation, caused by the popping open of small airways and alveoli collapsed by fluid or exudate during expiration. Stridor is a high-pitched sound occurring during inhalation or exhalation, indicating respiratory obstruction, commonly caused by croup, foreign bodies, or allergic reactions. Wheezing is a high-pitched whistling sound made while breathing, caused by narrowed airways, typically in asthma.

Ludwig’s Angina is a medical emergency that falls under the domain of ENT. The patient in question is displaying symptoms and indications that suggest the presence of this rare infection, which affects the soft tissues of the neck and the floor of the mouth. While it is typically caused by dental issues, it can also arise from other types of soft tissue infections in the neck. Due to the effectiveness of modern antibiotics and dental hygiene, Ludwig’s Angina is now quite uncommon, and many physicians may not be familiar with its presentation. However, it can lead to rapid deterioration and airway obstruction within a matter of minutes, necessitating immediate airway management and aggressive surgical intervention. If there is any suspicion of Ludwig’s Angina, it is crucial to transfer the patient to the emergency department without delay.

Understanding Ludwig’s Angina

Ludwig’s angina is a serious form of cellulitis that affects the soft tissues of the neck and the floor of the mouth. It is usually caused by an infection that originates from the teeth and spreads to the submandibular space. The condition is characterized by symptoms such as neck swelling, fever, and difficulty swallowing.

Ludwig’s angina is a medical emergency that requires immediate attention as it can lead to airway obstruction, which can be life-threatening. The management of this condition involves airway management and the administration of intravenous antibiotics.

Male adults are the most commonly affected by nasal polyps.

Understanding Nasal Polyps

Nasal polyps are a relatively uncommon condition affecting around 1% of adults in the UK. They are more commonly seen in men and are not typically found in children or the elderly. There are several associations with nasal polyps, including asthma (particularly late-onset asthma), aspirin sensitivity, infective sinusitis, cystic fibrosis, Kartagener’s syndrome, and Churg-Strauss syndrome. When asthma, aspirin sensitivity, and nasal polyposis occur together, it is known as Samter’s triad.

The most common features of nasal polyps include nasal obstruction, rhinorrhoea, sneezing, and a poor sense of taste and smell. However, if a patient experiences unilateral symptoms or bleeding, further investigation is always necessary.

If a patient is suspected of having nasal polyps, they should be referred to an ear, nose, and throat (ENT) specialist for a full examination. Treatment typically involves the use of topical corticosteroids, which can shrink polyp size in around 80% of patients. With proper management, most patients with nasal polyps can experience relief from their symptoms.

Phenytoin, ciclosporin, calcium channel blockers, and AML are all associated with gingival hyperplasia.

Understanding Gingival Hyperplasia and Its Causes

Gingival hyperplasia is a condition characterized by an abnormal growth of gum tissue, resulting in an enlarged and swollen appearance. This condition can be caused by various factors, including certain medications and medical conditions. Some of the drugs that have been linked to gingival hyperplasia include phenytoin, ciclosporin, and calcium channel blockers, particularly nifedipine. These drugs can cause an overgrowth of gum tissue, leading to discomfort and difficulty in maintaining proper oral hygiene.

Aside from medication, gingival hyperplasia can also be a symptom of acute myeloid leukemia, particularly the myelomonocytic and monocytic types. This type of cancer affects the blood and bone marrow, leading to abnormal growth of white blood cells and other blood components. As a result, the gums may become swollen and inflamed, making it difficult to eat, speak, and perform other daily activities.
