Migraine is a common neurological complaint, affecting approximately 16% of individuals throughout their lifetime. Vestibular migraine is characterized by the presence of migrainous symptoms along with recurring episodes of vertigo and/or unsteadiness. It is a leading cause of vertigo and the most frequent cause of spontaneous episodic vertigo. The disturbance in the vestibular system can manifest as part of the aura phase or occur independently. The duration of these episodes can range from a few seconds to several days, typically lasting for minutes to hours. Interestingly, they often occur without accompanying headaches. Diagnosing vestibular migraine is primarily based on ruling out other potential causes. For prolonged individual attacks, antivertiginous and antiemetic medications are commonly used. However, specific antimigraine drugs may not provide significant relief in rescue situations. The cornerstone of managing vestibular migraine lies in the use of prophylactic medication. In some cases, referral to a neurologist may be necessary, especially if the patient is experiencing acute symptoms for the first time.

Nasal packing is recommended for cases of bilateral epistaxis (nosebleeds on both sides) and when it is difficult to locate the source of bleeding. If initial first aid measures, such as applying pressure to the soft part of the nose, do not stop the bleeding or if there is no visible bleeding point, nasal packing is necessary. In the UK, the most commonly used methods for nasal packing are Merocel nasal tampons and rapid-rhino inflatable nasal packs. If anterior nasal packing fails to control the bleeding, posterior nasal packing with a Foley catheter may be considered. Ideally, this procedure should be performed by an ENT surgeon, but if specialist input is not immediately available, a trained clinician in the emergency department can carry it out.

Epistaxis, or nosebleed, is a common condition that can occur in both children and older adults. It is classified as either anterior or posterior, depending on the location of the bleeding. Anterior epistaxis usually occurs in younger individuals and arises from the nostril, most commonly from an area called Little’s area. These bleeds are usually not severe and account for the majority of nosebleeds seen in hospitals. Posterior nosebleeds, on the other hand, occur in older patients with conditions such as hypertension and atherosclerosis. The bleeding in posterior nosebleeds is likely to come from both nostrils and originates from the superior or posterior parts of the nasal cavity or nasopharynx.

The management of epistaxis involves assessing the patient for signs of instability and implementing measures to control the bleeding. Initial measures include sitting the patient upright with their upper body tilted forward and their mouth open. Firmly pinching the cartilaginous part of the nose for 10-15 minutes without releasing the pressure can also help stop the bleeding. If these measures are successful, a cream called Naseptin or mupirocin nasal ointment can be prescribed for further treatment.

If bleeding persists after the initial measures, nasal cautery or nasal packing may be necessary. Nasal cautery involves using a silver nitrate stick to cauterize the bleeding point, while nasal packing involves inserting nasal tampons or inflatable nasal packs to stop the bleeding. In cases of posterior bleeding, posterior nasal packing or surgery to tie off the bleeding vessel may be considered.

Complications of epistaxis can include nasal bleeding, hypovolemia, anemia, aspiration, and even death. Complications specific to nasal packing include sinusitis, septal hematoma or abscess, pressure necrosis, toxic shock syndrome, and apneic episodes. Nasal cautery can lead to complications such as septal perforation and caustic injury to the surrounding skin.

In children under the age of 2 presenting with epistaxis, it is important to refer them for further investigation as an underlying cause is more likely in this age group.

Tracheo-innominate fistula (TIF) should be considered as a possible diagnosis in patients experiencing bleeding after a tracheostomy. This bleeding, occurring between 3 days and 6 weeks after the tracheostomy procedure, should be treated as TIF until ruled out. While this complication is uncommon, it is extremely dangerous and often leads to death if not promptly addressed through surgical intervention. Therefore, any bleeding from a tracheostomy tube should be regarded as potentially life-threatening.

Further Reading:

Patients with tracheostomies may experience emergencies such as tube displacement, tube obstruction, and bleeding. Tube displacement can occur due to accidental dislodgement, migration, or erosion into tissues. Tube obstruction can be caused by secretions, lodged foreign bodies, or malfunctioning humidification devices. Bleeding from a tracheostomy can be classified as early or late, with causes including direct injury, anticoagulation, mucosal or tracheal injury, and granulation tissue.

When assessing a patient with a tracheostomy, an ABCDE approach should be used, with attention to red flags indicating a tracheostomy or laryngectomy emergency. These red flags include audible air leaks or bubbles of saliva indicating gas escaping past the cuff, grunting, snoring, stridor, difficulty breathing, accessory muscle use, tachypnea, hypoxia, visibly displaced tracheostomy tube, blood or blood-stained secretions around the tube, increased discomfort or pain, increased air required to keep the cuff inflated, tachycardia, hypotension or hypertension, decreased level of consciousness, and anxiety, restlessness, agitation, and confusion.

Algorithms are available for managing tracheostomy emergencies, including obstruction or displaced tube. Oxygen should be delivered to the face and stoma or tracheostomy tube if there is uncertainty about whether the patient has had a laryngectomy. Tracheostomy bleeding can be classified as early or late, with causes including direct injury, anticoagulation, mucosal or tracheal injury, and granulation tissue. Tracheo-innominate fistula (TIF) is a rare but life-threatening complication that occurs when the tracheostomy tube erodes into the innominate artery. Urgent surgical intervention is required for TIF, and management includes general resuscitation measures and specific measures such as bronchoscopy and applying direct digital pressure to the innominate artery.

When assessing a patient with epistaxis (nosebleed), it is important to start with a standard ABC assessment, focusing on the airway and hemodynamic status. Even if the bleeding appears to have stopped, it is crucial to evaluate the patient’s airway and circulation.

If active bleeding is still present and there are signs of hemodynamic compromise, immediate resuscitative and first aid measures should be initiated. Epistaxis should be treated as a circulatory emergency, especially in elderly patients, those with clotting disorders or bleeding tendencies, and individuals taking anticoagulants. In these cases, it is necessary to establish intravenous access using at least an 18-gauge (green) cannula and collect blood samples for tests such as full blood count, urea and electrolytes, clotting studies, and blood typing and crossmatching (depending on the amount of blood loss). These patients should be closely monitored in a majors area or a designated observation area, as dislodgement of a blood clot can lead to severe bleeding.

First aid measures to control bleeding include the following steps:
1. The patient should be seated upright with their body tilted forward and their mouth open. Lying down should be avoided, unless the patient feels faint or there are signs of hemodynamic compromise. Leaning forward helps reduce the flow of blood into the back of the throat.
2. The patient should be encouraged to spit out any blood that enters the throat and advised not to swallow it.
3. Firmly pinch the soft, cartilaginous part of the nose, compressing the nostrils for 10-15 minutes. Pressure should not be released, and the patient should breathe through their mouth.
4. If the patient is unable to comply with pinching their own nose, an alternative technique is to ask a relative or staff member to apply external pressure using a device like a swimmer’s nose clip.
5. It is important to dispel the misconception that compressing the bones of the nose will help stop the bleeding. Applying ice to the neck or forehead has not been proven to affect nasal blood flow. However, sucking on an ice cube or applying an ice pack directly to the nose may help reduce nasal blood flow.

If bleeding stops with first aid measures, it may be beneficial to apply a topical antiseptic preparation to reduce crusting and inflammation. Naseptin cream (containing chlorhexidine and neomycin) is commonly used and should be applied to the nostrils four times daily for 10 days.

One type of brainstem infarction is characterized by the presence of complete deafness on the same side as the affected area. This condition is unlikely to be caused by a transient ischemic attack (TIA) or stroke due to the patient’s age and absence of risk factors. Benign paroxysmal positional vertigo (BPPV) causes brief episodes of vertigo triggered by head movements. On the other hand, vestibular neuronitis (also known as vestibular neuritis) causes a persistent sensation of vertigo rather than intermittent episodes.

Meniere’s disease is a disorder of the inner ear that is characterized by recurrent episodes of vertigo, tinnitus, and low frequency hearing loss. The exact cause of the disease is unknown, but it is believed to be related to excessive pressure and dilation of the endolymphatic system in the middle ear. Meniere’s disease is more common in middle-aged adults, but can occur at any age and affects both men and women equally.

The clinical features of Meniere’s disease include episodes of vertigo that can last from minutes to hours. These attacks often occur in clusters, with several episodes happening in a week. 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 are common findings, and the Fukuda stepping test may also be positive. While symptoms are typically unilateral, bilateral symptoms may develop over time.

Rinne’s and Weber’s tests can be used to help diagnose Meniere’s disease. In Rinne’s test, air conduction should be better than bone conduction in both ears. In Weber’s test, the sound should be heard loudest in the unaffected (contralateral) side due to the sensorineural hearing loss.

The natural history of Meniere’s disease is that symptoms often resolve within 5-10 years, but most patients are left with some residual hearing loss. Psychological distress is common among patients with this condition.

The diagnostic criteria for Meniere’s disease include clinical features consistent with the disease, confirmed sensorineural hearing loss on audiometry, and exclusion of other possible causes.

Management of Meniere’s disease involves an ENT assessment to confirm the diagnosis and perform audiometry. Patients should be advised to inform the DVLA and may need to cease driving until their symptoms are under control. Acute attacks can be treated with buccal or intramuscular prochlorperazine, and hospital admission may be necessary in some cases. Betahistine may be beneficial for prevention of symptoms.

Peripheral and central vertigo can be differentiated based on certain characteristics. Peripheral vertigo typically has a sudden onset and is associated with more severe symptoms of vertigo. The vertigo symptoms may come and go intermittently. Individuals with peripheral vertigo often experience severe nausea and vomiting. Their vertigo is also affected by head movement, particularly in certain positions. Peripheral vertigo is usually not accompanied by any focal neurology. Nystagmus, which is an involuntary eye movement, tends to occur away from the side of the lesion. In some cases, hearing may also be impaired, as seen in conditions like Meniere’s disease and labyrinthitis.

On the other hand, central vertigo tends to have a gradual onset and milder symptoms of vertigo. The vertigo symptoms are constant and do not fluctuate. Nausea and vomiting may be present but are usually less severe compared to peripheral vertigo. Unlike peripheral vertigo, central vertigo is not influenced by head movement and is considered fixed. Individuals with central vertigo may experience new-onset headaches. Additionally, central vertigo is often accompanied by focal neurology, indicating involvement of specific areas of the brain. Nystagmus in central vertigo occurs towards the side of the lesion. Unlike peripheral vertigo, hearing is typically unaffected in central vertigo cases.

Infectious mononucleosis is typically a self-limiting infection that is primarily caused by the Epstein-Barr virus (EBV), a member of the human herpesvirus family. About 10% of cases are caused by cytomegalovirus (CMV) infection.

This clinical infection is most commonly observed in populations with a large number of young adults, such as university students and active-duty military personnel.

The main clinical features of infectious mononucleosis include a low-grade fever, fatigue, prolonged malaise, sore throat (often accompanied by tonsillar enlargement and exudate), a transient, fine, non-itchy rash, lymphadenopathy (most commonly in the cervical region), arthralgia and myalgia, mild enlargement of the liver and spleen, and jaundice (which is less common in young adults but more prevalent in the elderly).

To diagnose EBV infectious mononucleosis, a variety of unrelated non-EBV heterophile antibodies and specific EBV antibodies can be used.

1. Heterophile antibodies:
Around 70-90% of patients with EBV infectious mononucleosis produce heterophile antibodies, which are antibodies that react against antigens from other species. False positives can occur with hepatitis, malaria, toxoplasmosis, rubella, systemic lupus erythematosus (SLE), lymphoma, and leukemia. Two main screening tests can detect these antibodies and provide rapid results within a day:
– Paul-Bunnell test: Sheep red blood cells agglutinate in the presence of heterophile antibodies.
– Monospot test: Horse red blood cells agglutinate in the presence of heterophile antibodies.

2. EBV-specific antibodies:
Patients who remain heterophile-negative after six weeks are considered heterophile-negative and should be tested for EBV-specific antibodies. These antibodies are also useful in cases where a false positive heterophile antibody test is suspected.

Other useful investigations include a full blood count, which often shows a raised white cell count with lymphocytosis and atypical lymphocytes in more than 20% of cases, an elevated erythrocyte sedimentation rate (ESR) in most patients, liver function tests (LFTs) that may show mild elevation of serum transaminases, throat swabs to rule out group A streptococci pharyngitis as a differential diagnosis, and abdominal ultrasound if splenomegaly is present.

The FeverPAIN score is a scoring system recommended by the current NICE guidelines for assessing acute sore throats. It consists of five items: fever in the last 24 hours, purulence, attendance within three days, inflamed tonsils, and no cough or coryza. Based on the score, recommendations for antibiotic use are as follows: a score of 0-1 indicates an unlikely streptococcal infection, with antibiotics not recommended; a score of 2-3 suggests a 34-40% chance of streptococcus, and delayed prescribing of antibiotics may be considered; a score of 4 or higher indicates a 62-65% chance of streptococcus, and immediate antibiotic use is recommended for severe cases, or a short back-up prescription may be given for 48 hours.

The Fever PAIN score was developed through a study involving 1760 adults and children aged three and over. It was tested in a trial comparing three prescribing strategies: empirical delayed prescribing, score-directed prescribing, and a combination of the score with a near-patient test (NPT) for streptococcus. The use of the score resulted in faster symptom resolution and reduced antibiotic prescribing by one third. The addition of the NPT did not provide any additional benefit.

According to the current NICE guidelines, if antibiotics are necessary, phenoxymethylpenicillin is recommended as the first-choice antibiotic. In cases of true penicillin allergy, clarithromycin can be used as an alternative. For pregnant women with a penicillin allergy, erythromycin is prescribed. It is important to note that the threshold for prescribing antibiotics should be lower for individuals at risk of rheumatic fever and vulnerable groups managed in primary care, such as infants, the elderly, and those who are immunosuppressed or immunocompromised. Antibiotics should not be withheld if the person has severe symptoms and there are concerns about their clinical condition.

This patient is displaying symptoms and signs that are consistent with a vestibular schwannoma, which is also known as an acoustic neuroma. A vestibular schwannoma typically affects the 5th and 8th cranial nerves and is characterized by the following classic presentations: gradual deterioration of hearing in one ear, facial numbness and tingling, tinnitus, and vertigo. It is also possible for the patient to have a history of headaches, and in rare cases, the 7th, 9th, and 10th cranial nerves may be affected. It is recommended that this patient be referred to either an ENT specialist or a neurosurgeon for further assessment, including an MRI of the internal auditory meatus. The main treatment options for vestibular schwannoma include surgery, radiotherapy, and stereotactic radiosurgery.

In cases of conductive hearing loss, the Rinne test result is negative on the affected side, meaning that bone conduction is greater than air conduction. Additionally, the Weber test result will lateralize to the affected side. If the Weber test lateralizes to the right, it indicates either sensorineural hearing loss in the left ear (opposite side) or conductive hearing loss in the right ear (same side). A positive Rinne test result, where air conduction is greater than bone conduction, is typically seen in individuals with normal hearing or sensorineural hearing loss. In the case of conductive hearing loss in the right ear, a negative Rinne test result would be expected on the right side, indicating that bone conduction is greater than air conduction.

Hearing loss is a common complaint that can be caused by various conditions affecting different parts of the ear and nervous system. The outer ear is the part of the ear outside the eardrum, while the middle ear is located between the eardrum and the cochlea. The inner ear is within the bony labyrinth and consists of the vestibule, semicircular canals, and cochlea. The vestibulocochlear nerve connects the inner ear to the brain.

Hearing loss can be classified based on severity, onset, and type. Severity is determined by the quietest sound that can be heard, measured in decibels. It can range from mild to profound deafness. Onset can be sudden, rapidly progressive, slowly progressive, or fluctuating. Type of hearing loss can be either conductive or sensorineural. Conductive hearing loss is caused by issues in the external ear, eardrum, or middle ear that disrupt sound transmission. Sensorineural hearing loss is caused by problems in the cochlea, auditory nerve, or higher auditory processing pathways.

To diagnose sensorineural and conductive deafness, a 512 Hz tuning fork is used to perform Rinne and Weber’s tests. These tests help determine the type of hearing loss based on the results. In Rinne’s test, air conduction (AC) and bone conduction (BC) are compared, while Weber’s test checks for sound lateralization.

Cholesteatoma is a condition characterized by the abnormal accumulation of skin cells in the middle ear or mastoid air cell spaces. It is believed to develop from a retraction pocket that traps squamous cells. Cholesteatoma can cause the accumulation of keratin and the destruction of adjacent bones and tissues due to the production of destructive enzymes. It can lead to mixed sensorineural and conductive deafness as it affects both the middle and inner ear.

The CENTOR score is a clinical prediction rule used to assess the likelihood of a patient having a streptococcal infection, which is commonly associated with sore throat. It is based on the presence or absence of four clinical criteria: fever, tonsillar exudate, tender anterior cervical lymphadenopathy, and absence of cough. Each criterion is assigned one point, and the total score ranges from 0 to 4. In this case, the patient has a fever, tonsillar exudate, tender anterior cervical lymphadenopathy, and no cough, resulting in a CENTOR score of 4. A higher score indicates a higher likelihood of a streptococcal infection, and further diagnostic testing or treatment may be warranted.

Pharyngitis and tonsillitis are common conditions that cause inflammation in the throat. Pharyngitis refers to inflammation of the oropharynx, which is located behind the soft palate, while tonsillitis refers to inflammation of the tonsils. These conditions can be caused by a variety of pathogens, including viruses and bacteria. The most common viral causes include rhinovirus, coronavirus, parainfluenza virus, influenza types A and B, adenovirus, herpes simplex virus type 1, and Epstein Barr virus. The most common bacterial cause is Streptococcus pyogenes, also known as Group A beta-hemolytic streptococcus (GABHS). Other bacterial causes include Group C and G beta-hemolytic streptococci and Fusobacterium necrophorum.

Group A beta-hemolytic streptococcus is the most concerning pathogen as it can lead to serious complications such as rheumatic fever and glomerulonephritis. These complications can occur due to an autoimmune reaction triggered by antigen/antibody complex formation or from cell damage caused by bacterial exotoxins.

When assessing a patient with a sore throat, the clinician should inquire about the duration and severity of the illness, as well as associated symptoms such as fever, malaise, headache, and joint pain. It is important to identify any red flags and determine if the patient is immunocompromised. Previous non-suppurative complications of Group A beta-hemolytic streptococcus infection should also be considered, as there is an increased risk of further complications with subsequent infections.

Red flags that may indicate a more serious condition include severe pain, neck stiffness, or difficulty swallowing. These symptoms may suggest epiglottitis or a retropharyngeal abscess, which require immediate attention.

To determine the likelihood of a streptococcal infection and the need for antibiotic treatment, two scoring systems can be used: CENTOR and FeverPAIN. The CENTOR criteria include tonsillar exudate, tender anterior cervical lymphadenopathy or lymphadenitis, history of fever, and absence of cough. The FeverPAIN criteria include fever, purulence, rapid onset of symptoms, severely inflamed tonsils, and absence of cough or coryza. Based on the scores from these criteria, the likelihood of a streptococcal infection can be estimated, and appropriate management can be undertaken. can

Acute epiglottitis is inflammation of the epiglottis, which can be life-threatening if not treated promptly. When the soft tissues surrounding the epiglottis are also affected, it is called acute supraglottitis. This condition is most commonly seen in children between the ages of 3 and 5, but it can occur at any age, with adults typically presenting in their 40s and 50s.

In the past, Haemophilus influenzae type B was the main cause of acute epiglottitis, but with the introduction of the Hib vaccination, it has become rare in children. Streptococcus spp. is now the most common causative organism. Other potential culprits include Staphylococcus aureus, Pseudomonas spp., Moraxella catarrhalis, Mycobacterium tuberculosis, and the herpes simplex virus. In immunocompromised patients, Candida spp. and Aspergillus spp. infections can occur.

The typical symptoms of acute epiglottitis include fever, sore throat, painful swallowing, difficulty swallowing secretions (especially in children who may drool), muffled voice, stridor, respiratory distress, rapid heartbeat, tenderness in the front of the neck over the hyoid bone, ear pain, and swollen lymph nodes in the neck. Some patients may also exhibit the tripod sign, where they lean forward on outstretched arms to relieve upper airway obstruction.

To diagnose acute epiglottitis, fibre-optic laryngoscopy is considered the gold standard investigation. However, this procedure should only be performed by an anaesthetist in a setting prepared for intubation or tracheostomy in case of airway obstruction. Other useful tests include a lateral neck X-ray to look for the thumbprint sign, throat swabs, blood cultures, and a CT scan of the neck if an abscess is suspected.

When dealing with a case of acute epiglottitis, it is crucial not to panic or distress the patient, especially in pediatric cases. Avoid attempting to examine the throat with a tongue depressor, as this can trigger spasm and worsen airway obstruction. Instead, keep the patient as calm as possible and immediately call a senior anaesthetist, a senior paediatrician, and an ENT surgeon. Nebulized adrenaline can be used as a temporary measure if there is critical airway obstruction.

Phenoxymethylpenicillin is the preferred antibiotic for treating streptococcal sore throat, especially in patients with a CENTOR score of 3/4 and a FeverPAIN score of 4/5. In such cases, antibiotics are necessary to effectively treat the infection.

In a patient with severe otitis externa on the left side, it is expected that they will experience conductive deafness on the left side. This means that their ability to hear sound will be impaired due to a problem in the ear canal or middle ear. When conducting a Rinne’s test, a vibrating 512 Hz tuning fork is placed on the mastoid process until the patient can no longer hear the sound. Then, the top of the tuning fork is positioned 2 cm from the external auditory meatus, and the patient is asked where they hear the sound loudest.

In individuals with normal hearing, the sound from the tuning fork should still be audible outside the external auditory canal even after it can no longer be heard on the mastoid. This is because air conduction should be better than bone conduction. However, in cases of conductive hearing loss, the patient will no longer be able to hear the tuning fork once it is removed from the mastoid. This indicates that their bone conduction is greater than their air conduction, suggesting an obstruction in the ear canal that prevents sound waves from reaching the cochlea. This is referred to as a true negative result.

It is important to note that a Rinne’s test may yield a false negative result if the patient has a severe unilateral sensorineural deficit. In this case, they may still sense the sound in the unaffected ear due to the transmission of sound through the base of the skull. In contrast, individuals with sensorineural hearing loss will have diminished ability to hear the tuning fork both on the mastoid and outside the external auditory canal compared to the opposite ear. The sound will disappear earlier on the mastoid and outside the external auditory canal in the affected ear.

When performing Weber’s test, a vibrating 512 Hz tuning fork is placed on the center of the patient’s forehead. The patient is then asked if they perceive the sound in the middle of the forehead or if it lateralizes to one side. If the sound lateralizes to one side, it can indicate either ipsilateral conductive hearing loss or contralateral sensorineural hearing loss.

If someone is suspected to have CSF rhinorrhoea, their nasal discharge should be tested for beta-2 transferrin. This test is considered the most accurate diagnostic method to confirm the presence of CSF rhinorrhoea and has replaced glucose testing.

Zygomatic injuries, also known as zygomatic complex fractures, involve fractures of the zygoma bone and often affect surrounding bones such as the maxilla and temporal bones. These fractures can be classified into four positions: the lateral and inferior orbital rim, the zygomaticomaxillary buttress, and the zygomatic arch. The full extent of these injuries may not be visible on plain X-rays and may require a CT scan for accurate diagnosis.

Zygomatic fractures can pose risks to various structures in the face. The temporalis muscle and coronoid process of the mandible may become trapped in depressed fractures of the zygomatic arch. The infraorbital nerve, which passes through the infraorbital foramen, can be injured in zygomaticomaxillary complex fractures. In orbital floor fractures, the inferior rectus muscle may herniate into the maxillary sinus.

Clinical assessment of zygomatic injuries involves observing facial asymmetry, depressed facial bones, contusion, and signs of eye injury. Visual acuity must be assessed, and any persistent bleeding from the nose or mouth should be noted. Nasal injuries, including septal hematoma, and intra-oral abnormalities should also be evaluated. Tenderness of facial bones and the temporomandibular joint should be assessed, along with any step deformities or crepitus. Eye and jaw movements must also be evaluated.

Imaging for zygomatic injuries typically includes facial X-rays, such as occipitomental views, and CT scans for a more detailed assessment. It is important to consider the possibility of intracranial hemorrhage and cervical spine injury in patients with facial fractures.

Management of most zygomatic fractures can be done on an outpatient basis with maxillofacial follow-up, assuming the patient is stable and there is no evidence of eye injury. However, orbital floor fractures should be referred immediately to ophthalmologists or maxillofacial surgeons. Zygomatic arch injuries that restrict mouth opening or closing due to entrapment of the temporalis muscle or mandibular condyle also require urgent referral. Nasal fractures, often seen in conjunction with other facial fractures, can be managed by outpatient ENT follow-up but should be referred urgently if there is uncontrolled epistaxis, CSF rhinorrhea, or septal hematoma.

According to a Cochrane review conducted in 2008, it was discovered that approximately 80% of children experiencing acute otitis media were able to recover within a span of two days. However, the use of antibiotics only resulted in a reduction of pain for about 7% of children after the same two-day period. Furthermore, the administration of antibiotics did not show any significant impact on the rates of hearing loss, recurrence, or perforation. In cases where antibiotics are deemed necessary for children with otitis media, some indications include being under the age of two, experiencing discharge from the ear (otorrhoea), and having bilateral acute otitis media.

When assessing a patient with epistaxis (nosebleed), it is important to start with a standard ABC assessment, focusing on the airway and hemodynamic status. Even if the bleeding appears to have stopped, it is crucial to evaluate the patient’s condition. If active bleeding is still present and there are signs of hemodynamic compromise, immediate resuscitative and first aid measures should be initiated.

Epistaxis should be treated as a circulatory emergency, especially in elderly patients, those with clotting disorders or bleeding tendencies, and individuals taking anticoagulants. In these cases, it is necessary to establish intravenous access using at least an 18-gauge (green) cannula. Blood samples, including a full blood count, urea and electrolytes, clotting profile, and group and save (depending on the amount of blood loss), should be sent for analysis. Patients should be assigned to a majors or closely observed area, as dislodgement of a blood clot can lead to severe bleeding.

First aid measures to control bleeding include the following steps:
1. The patient should be seated upright with their body tilted forward and their mouth open. Lying down should be avoided, unless the patient feels faint or there is evidence of hemodynamic compromise. Leaning forward helps reduce the flow of blood into the nasopharynx.
2. The patient should be encouraged to spit out any blood that enters the throat and advised not to swallow it.
3. Firmly pinch the soft, cartilaginous part of the nose, compressing the nostrils for 10-15 minutes. Pressure should not be released, and the patient should breathe through their mouth.
4. If the patient is unable to comply, an alternative technique is to ask a relative, staff member, or use an external pressure device like a swimmer’s nose clip.
5. It is important to dispel the misconception that compressing the bones will help stop the bleeding. Applying ice to the neck or forehead does not influence nasal blood flow. However, sucking on an ice cube or applying an ice pack directly to the nose may reduce nasal blood flow.

If bleeding stops with first aid measures, it is recommended to apply a topical antiseptic preparation to reduce crusting and vestibulitis. Naseptin cream (containing chlorhexidine and neomycin) is commonly used and should be applied to the nostrils four times daily for 10 days.

Gentamicin has the potential to cause a severe form of hearing loss known as sensorineural hearing loss. In cases of severe sensorineural hearing loss, the Weber’s test will show a lateralization towards the side of the unaffected ear. Additionally, the Rinne’s test may yield a false negative result, with the patient perceiving the sound in the unaffected ear.

To perform the Rinne’s test, a 512 Hz tuning fork is vibrated and then placed on the mastoid process until the sound is no longer audible. The top of the tuning fork is then positioned 2 cm away from the external auditory meatus, and the patient is asked to indicate where they hear the sound loudest.

In individuals with normal hearing, the tuning fork should still be audible outside the external auditory canal even after it can no longer be heard on the mastoid. This is because air conduction should be more effective than bone conduction.

In cases of conductive hearing loss, the patient will no longer be able to hear the tuning fork once it is no longer audible on the mastoid. This indicates that their bone conduction is greater than their air conduction, suggesting an obstruction in the passage of sound waves through the ear canal and into the cochlea. This is considered a true negative result.

However, a Rinne’s test may yield a false negative result if the patient has a severe unilateral sensorineural deficit and perceives the sound in the unaffected ear through the transmission of sound waves through the base of the skull.

In sensorineural hearing loss, the ability to perceive the tuning fork both on the mastoid and outside the external auditory canal is equally diminished compared to the opposite ear. While they will still hear the tuning fork outside the external auditory canal, the sound will disappear earlier on the mastoid process and outside the external auditory canal compared to the other ear.

To perform the Weber’s test, a 512 Hz tuning fork is vibrated and placed on the center of the patient’s forehead. The patient is then asked if they perceive the sound in the middle of the forehead or if it lateralizes to one side or the other.

If the sound lateralizes to one side, it can indicate either ipsilateral conductive hearing loss or contralateral sensorineural hearing loss.

When assessing a patient with epistaxis (nosebleed), it is important to start with a standard ABC assessment, focusing on the airway and hemodynamic status. Even if the bleeding appears to have stopped, it is crucial to evaluate the patient’s airway and circulation.

If active bleeding is still present and there are signs of hemodynamic compromise, immediate resuscitative and first aid measures should be initiated. Epistaxis should be treated as a circulatory emergency, especially in elderly patients, those with clotting disorders or bleeding tendencies, and individuals taking anticoagulants. In these cases, it is necessary to establish intravenous access using at least an 18-gauge (green) cannula and collect blood samples for tests such as full blood count, urea and electrolytes, clotting studies, and blood typing and crossmatching (depending on the amount of blood loss). These patients should be closely monitored in a majors area or a designated observation area, as dislodgement of a blood clot can lead to severe bleeding.

First aid measures to control bleeding include the following steps:
1. The patient should be seated upright with their body tilted forward and their mouth open. Lying down should be avoided, unless the patient feels faint or there are signs of hemodynamic compromise. Leaning forward helps reduce the flow of blood into the back of the throat.
2. The patient should be encouraged to spit out any blood that enters the throat and advised not to swallow it.
3. Firmly pinch the soft, cartilaginous part of the nose, compressing the nostrils for 10-15 minutes. Pressure should not be released, and the patient should breathe through their mouth.
4. If the patient is unable to comply with pinching their own nose, an alternative technique is to ask a relative or staff member to apply external pressure using a device like a swimmer’s nose clip.
5. It is important to dispel the misconception that compressing the bones of the nose will help stop the bleeding. Applying ice to the neck or forehead has not been proven to affect nasal blood flow. However, sucking on an ice cube or applying an ice pack directly to the nose may help reduce nasal blood flow.

If bleeding stops with first aid measures, it may be beneficial to apply a topical antiseptic preparation to reduce crusting and inflammation. Naseptin cream (containing chlorhexidine and neomycin) is commonly used and should be applied to the nostrils four times daily for 10 days.

Meniere’s disease is a condition that affects the inner ear due to changes in fluid volume within the vestibular labyrinth. This leads to the progressive distension of the labyrinth, known as endolymphatic hydrops, which causes damage to the vestibular system and the cochlea. The classic symptoms associated with Meniere’s disease are vertigo, hearing loss, and tinnitus.

The main clinical features of Meniere’s disease include episodes of vertigo that typically last for 2-3 hours. These episodes are usually shorter than 24 hours in duration. Hearing loss, which is often gradual and affects only one ear, is also a common symptom. Tinnitus, a ringing or buzzing sound in the ears, is frequently associated with Meniere’s disease. Other symptoms may include a sensation of fullness or pressure in the ears, as well as nausea and vomiting. Nystagmus, an involuntary eye movement, may occur away from the side of the lesion. Meniere’s disease is more prevalent in individuals who suffer from migraines.

The management of Meniere’s disease aims to alleviate acute attacks, reduce their severity and frequency, and improve hearing while minimizing the impact of tinnitus. If Meniere’s disease is suspected, patients should be referred to an ear, nose, and throat specialist.

During acute attacks, medications such as prochlorperazine, cinnarizine, and cyclizine can help reduce nausea and vertigo symptoms. If vomiting is present, buccal or intramuscular administration of these medications may be necessary. In severe cases, hospital admission may be required to prevent dehydration.

For long-term prevention, lifestyle measures can be beneficial. Avoiding caffeine, chocolate, alcohol, and tobacco is recommended. Excessive fatigue should also be avoided. Following a low-salt diet may be helpful. Betahistine, a medication that initially starts at a dose of 16 mg three times a day, can be used for prophylaxis to reduce the frequency and severity of attacks. Diuretics may also be beneficial, but they are typically not recommended for primary care use.

Overall, the management of Meniere’s disease involves a combination of lifestyle changes and medication to control symptoms and improve the patient’s quality of life.

Acute epiglottitis is inflammation of the epiglottis, which can be life-threatening if not treated promptly. When the soft tissues surrounding the epiglottis are also affected, it is called acute supraglottitis. This condition is most commonly seen in children between the ages of 3 and 5, but it can occur at any age, with adults typically presenting in their 40s and 50s.

In the past, Haemophilus influenzae type B was the main cause of acute epiglottitis, but with the introduction of the Hib vaccination, it has become rare in children. Streptococcus spp. is now the most common causative organism. Other potential culprits include Staphylococcus aureus, Pseudomonas spp., Moraxella catarrhalis, Mycobacterium tuberculosis, and the herpes simplex virus. In immunocompromised patients, Candida spp. and Aspergillus spp. infections can occur.

The typical symptoms of acute epiglottitis include fever, sore throat, painful swallowing, difficulty swallowing secretions (especially in children who may drool), muffled voice, stridor, respiratory distress, rapid heartbeat, tenderness in the front of the neck over the hyoid bone, ear pain, and swollen lymph nodes in the neck. Some patients may also exhibit the tripod sign, where they lean forward on outstretched arms to relieve upper airway obstruction.

To diagnose acute epiglottitis, fibre-optic laryngoscopy is considered the gold standard investigation. However, this procedure should only be performed by an anaesthetist in a setting prepared for intubation or tracheostomy in case of airway obstruction. Other useful tests include a lateral neck X-ray to look for the thumbprint sign, throat swabs, blood cultures, and a CT scan of the neck if an abscess is suspected.

When dealing with a case of acute epiglottitis, it is crucial not to panic or distress the patient, especially in pediatric cases. Avoid attempting to examine the throat with a tongue depressor, as this can trigger spasm and worsen airway obstruction. Instead, keep the patient as calm as possible and immediately call a senior anaesthetist, a senior paediatrician, and an ENT surgeon. Nebulized adrenaline can be used as a temporary measure if there is critical airway obstruction.

This individual is diagnosed with an acquired cholesteatoma, which is an expanding growth of the stratified keratinising epithelium in the middle ear. It develops due to dysfunction of the Eustachian tube and chronic otitis media caused by the retraction of the squamous elements of the tympanic membrane into the middle ear space.

The most important method for assessing the presence of a cholesteatoma is otoscopy. A retraction pocket observed in the attic or posterosuperior quadrant of the tympanic membrane is a characteristic sign of an acquired cholesteatoma. This is often accompanied by the presence of granulation tissue and squamous debris. The presence of a granular polyp within the ear canal also strongly suggests a cholesteatoma.

If left untreated, a cholesteatoma can lead to various complications including conductive deafness, facial nerve palsy, brain abscess, meningitis, and labyrinthitis. Therefore, it is crucial to urgently refer this individual to an ear, nose, and throat (ENT) specialist for a CT scan and surgical removal of the lesion.

A 512 Hz tuning fork is recommended for conducting both the Rinne’s and Weber’s tests. However, a lower-pitched 128 Hz tuning fork is commonly used to assess vibration sense during a peripheral nervous system examination. Although a 256 Hz tuning fork can be used for both tests, it is considered less reliable.

To perform the Weber’s test, the 512 Hz tuning fork should be set in motion and then placed on the center of the patient’s forehead. The patient should be asked if they perceive the sound in the middle of their forehead or if it is heard more on one side.

If the sound is heard more on one side, it may indicate either ipsilateral conductive hearing loss or contralateral sensorineural hearing loss.

When performing Weber’s test, if the sound lateralizes to the unaffected side, it suggests sensorineural hearing loss in the opposite ear. For example, if the sound lateralizes to the left, it indicates sensorineural hearing loss in the right ear. On the other hand, if there is conductive hearing loss in the left ear, the sound will lateralize to the affected side. Additionally, a positive Rinne test result, where air conduction is greater than bone conduction, is typically seen in normal hearing and sensorineural loss. Conversely, a negative Rinne test result, where bone conduction is greater than air conduction, is expected in cases of conductive hearing loss. In summary, these test results can help identify the presence of sensorineural loss in the opposite ear.

Hearing loss is a common complaint that can be caused by various conditions affecting different parts of the ear and nervous system. The outer ear is the part of the ear outside the eardrum, while the middle ear is located between the eardrum and the cochlea. The inner ear is within the bony labyrinth and consists of the vestibule, semicircular canals, and cochlea. The vestibulocochlear nerve connects the inner ear to the brain.

Hearing loss can be classified based on severity, onset, and type. Severity is determined by the quietest sound that can be heard, measured in decibels. It can range from mild to profound deafness. Onset can be sudden, rapidly progressive, slowly progressive, or fluctuating. Type of hearing loss can be either conductive or sensorineural. Conductive hearing loss is caused by issues in the external ear, eardrum, or middle ear that disrupt sound transmission. Sensorineural hearing loss is caused by problems in the cochlea, auditory nerve, or higher auditory processing pathways.

To diagnose sensorineural and conductive deafness, a 512 Hz tuning fork is used to perform Rinne and Weber’s tests. These tests help determine the type of hearing loss based on the results. In Rinne’s test, air conduction (AC) and bone conduction (BC) are compared, while Weber’s test checks for sound lateralization.

Cholesteatoma is a condition characterized by the abnormal accumulation of skin cells in the middle ear or mastoid air cell spaces. It is believed to develop from a retraction pocket that traps squamous cells. Cholesteatoma can cause the accumulation of keratin and the destruction of adjacent bones and tissues due to the production of destructive enzymes. It can lead to mixed sensorineural and conductive deafness as it affects both the middle and inner ear.

An acoustic neuroma, also referred to as a vestibular schwannoma, is a slow-growing tumor that develops from the Schwann cells of the vestibulocochlear nerve (8th cranial nerve). These growths are typically found at the cerebellopontine angle or within the internal auditory canal.

The most commonly affected nerves are the vestibulocochlear and trigeminal nerves. Patients typically present with a gradual deterioration of hearing in one ear, along with numbness and tingling in the face, ringing in the ears, and episodes of dizziness. Additionally, some patients may have a history of headaches. In rare cases, the facial nerve, glossopharyngeal nerve, vagus nerve, or accessory nerve may also be affected.

It is important to note that the trochlear nerve, which passes through the superior orbital fissure, is not impacted by an acoustic neuroma.

Croup, also known as laryngo-tracheo-bronchitis, is typically caused by the parainfluenza virus. Other viruses such as rhinovirus, influenza, and respiratory syncytial viruses can also be responsible. Before the onset of stridor, there is usually a mild cold-like illness that lasts for 1-2 days. Symptoms reach their peak at 1-3 days, with the cough often being worse at night. A milder cough may persist for another 7-10 days.

A barking cough is a characteristic symptom of croup, but it does not indicate the severity of the condition. To reduce airway swelling, dexamethasone and prednisolone are commonly used. Nebulized budesonide can be an alternative if the child is experiencing vomiting. However, it’s important to note that steroids do not shorten the duration of the illness. In severe cases, nebulized adrenaline can be administered.

Hospitalization for croup is rare and typically reserved for children who are experiencing increasing respiratory distress or showing signs of drowsiness/agitation. The Westley croup score is a useful tool for assessing the child’s condition and making appropriate management decisions. Children with moderate (score 2-7) or severe croup (score >7) may require hospital admission. On the other hand, many children with mild croup (score 0-1) can be safely discharged and treated at home.

The Westley croup score is determined based on the following criteria: the presence of stridor when agitated, the severity of retractions, air entry, SaO2 levels below 92%, and the child’s conscious level. In this particular case, the child’s Westley croup score is 2 points, indicating the presence of stridor when agitated and mild retractions.

For mild cases of otitis externa, using ear drops or spray as the initial treatment is a reasonable option. The insertion of a medicated wick, known as a Pope wick, is typically reserved for patients with severely narrowed external auditory canals. Microsuction, on the other hand, is helpful for patients with excessive debris in their ear canal but is not necessary for this particular patient. In general, microsuction is usually only used for severe cases of otitis externa that require referral to an ear, nose, and throat specialist for further management.

Otitis externa is inflammation of the skin and subdermis of the external ear canal. It can be acute, lasting less than 6 weeks, or chronic, lasting more than 3 months. Malignant otitis externa, also known as necrotising otitis externa, is a severe and potentially life-threatening infection that can spread to the bones and surrounding structures of the ear. It is most commonly caused by Pseudomonas aeruginosa.

Symptoms of malignant otitis externa include severe and persistent ear pain, headache, discharge from the ear, fever, malaise, vertigo, and profound hearing loss. It can also lead to facial nerve palsy and other cranial nerve palsies. In severe cases, the infection can spread to the central nervous system, causing meningitis, brain abscess, and sepsis.

Acute otitis externa is typically caused by Pseudomonas aeruginosa or Staphylococcus aureus, while chronic otitis externa can be caused by fungal infections such as Aspergillus or Candida albicans. Risk factors for otitis externa include eczema, psoriasis, dermatitis, acute otitis media, trauma to the ear canal, foreign bodies in the ear, water exposure, ear canal obstruction, and long-term antibiotic or steroid use.

Clinical features of otitis externa include itching of the ear canal, ear pain, tenderness of the tragus and/or pinna, ear discharge, hearing loss if the ear canal is completely blocked, redness and swelling of the ear canal, debris in the ear canal, and cellulitis of the pinna and adjacent skin. Tender regional lymphadenitis is uncommon.

Management of acute otitis externa involves general ear care measures, optimizing any underlying medical or skin conditions that are risk factors, avoiding the use of hearing aids or ear plugs if there is a suspected contact allergy, and avoiding the use of ear drops if there is a suspected allergy to any of its ingredients. Treatment options include over-the-counter acetic acid 2% ear drops or spray, aural toileting via dry swabbing, irrigation, or microsuction, and prescribing topical antibiotics with or without a topical corticosteroid. Oral antibiotics may be prescribed in severe cases or for immunocompromised individuals.

Follow-up is advised if symptoms do not improve within 48-72 hours of starting treatment, if symptoms have not fully resolved

Malignant otitis externa, also known as necrotising otitis externa, is a severe infection that affects the external auditory canal and spreads to the temporal bone and nearby tissues, leading to skull base osteomyelitis. The primary cause of this condition is usually an infection by Pseudomonas aeruginosa. It is commonly observed in older individuals with diabetes.

To control nosebleeds, it is recommended to have the patient sit upright with their upper body tilted forward and their mouth open. Apply firm pressure to the cartilaginous part of the nose, just in front of the bony septum, and hold it for 10-15 minutes without releasing the pressure.

Further Reading:

Epistaxis, or nosebleed, is a common condition that can occur in both children and older adults. It is classified as either anterior or posterior, depending on the location of the bleeding. Anterior epistaxis usually occurs in younger individuals and arises from the nostril, most commonly from an area called Little’s area. These bleeds are usually not severe and account for the majority of nosebleeds seen in hospitals. Posterior nosebleeds, on the other hand, occur in older patients with conditions such as hypertension and atherosclerosis. The bleeding in posterior nosebleeds is likely to come from both nostrils and originates from the superior or posterior parts of the nasal cavity or nasopharynx.

The management of epistaxis involves assessing the patient for signs of instability and implementing measures to control the bleeding. Initial measures include sitting the patient upright with their upper body tilted forward and their mouth open. Firmly pinching the cartilaginous part of the nose for 10-15 minutes without releasing the pressure can also help stop the bleeding. If these measures are successful, a cream called Naseptin or mupirocin nasal ointment can be prescribed for further treatment.

If bleeding persists after the initial measures, nasal cautery or nasal packing may be necessary. Nasal cautery involves using a silver nitrate stick to cauterize the bleeding point, while nasal packing involves inserting nasal tampons or inflatable nasal packs to stop the bleeding. In cases of posterior bleeding, posterior nasal packing or surgery to tie off the bleeding vessel may be considered.

Complications of epistaxis can include nasal bleeding, hypovolemia, anemia, aspiration, and even death. Complications specific to nasal packing include sinusitis, septal hematoma or abscess, pressure necrosis, toxic shock syndrome, and apneic episodes. Nasal cautery can lead to complications such as septal perforation and caustic injury to the surrounding skin.

In children under the age of 2 presenting with epistaxis, it is important to refer them for further investigation as an underlying cause is more likely in this age group.

Two scoring systems are suggested by NICE to aid in the evaluation of sore throat: The Centor Clinical Prediction Score and The FeverPAIN Score.

The FeverPAIN score was developed from a study involving 1760 adults and children aged three and above. The score was tested in a trial that compared three prescribing strategies: empirical delayed prescribing, using the score to guide prescribing, or a combination of the score with the use of a near-patient test (NPT) for streptococcus. Utilizing the score resulted in faster symptom resolution and a reduction in the prescription of antibiotics (both reduced by one third). The inclusion of the NPT did not provide any additional benefit.

The score comprises of five factors, each of which is assigned one point: Fever (Temp >38°C) in the last 24 hours, Purulence, Attended rapidly in under three days, Inflamed tonsils, and No cough or coryza.

Based on the score, the recommendations are as follows:
– Score 0-1 = 13-18% likelihood of streptococcus infection, antibiotics are not recommended.
– Score 2-3 = 34-40% likelihood of streptococcus infection, consider delayed prescribing of antibiotics (3-5 day ‘backup prescription’).
– Score 4-5 = 62-65% likelihood of streptococcus infection, use immediate antibiotics if severe, or a 48-hour short ‘backup prescription.’
