Recurrent or chronic tonsillitis is a clear indication for tonsillectomy, which is the surgical removal of the palatine tonsils. One common complication of this procedure is bleeding, which occurs in approximately 0.5-2% of cases. The bleeding that occurs after tonsillectomy is typically venous in nature and most frequently originates from the external palatine vein. This vein drains the lateral tonsillar region and ultimately empties into the facial vein. Additionally, bleeding can also arise from the tonsillar branch of the facial artery, which supplies the inferior pole of the palatine tonsil.

Nasal cautery is a suitable option for patients who are experiencing epistaxis (nosebleeds) and have not responded to initial measures. It is particularly effective when a specific bleeding point in the anterior nasal septum (known as Little’s area) has been identified. This procedure is recommended for adult patients who have already undergone an appropriate period of nasal pressure application (10-15 minutes). It is important to note that naseptin or mupirocin should not be used to control active bleeding, but rather after the bleeding has been successfully managed. Nasal packing, on the other hand, is a more invasive procedure that requires hospital admission and is typically reserved for cases where the bleeding point cannot be visualized or when cautery has been unsuccessful.

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.

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.

When attempting to ventilate a patient with a tracheostomy, the first approach is usually through the mouth. If this is not successful, ventilation through the tracheostomy stoma is appropriate. After removing the tracheostomy, the doctor should begin ventilating the patient through the mouth by performing standard oral manoeuvres and covering the stoma with a hand or swab. If these measures fail, the clinician should then proceed to ventilate through the tracheostomy stoma using a bag valve mask and appropriate adjuncts such as oral or nasal adjuncts or an LMA.

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.

The initial step in managing a patient with uncomplicated epistaxis is to have the patient sit up and instruct them to apply direct pressure to the soft, fleshy part of their nose for a duration of 10 minutes.

If the bleeding persists after the 10-minute period, the next course of action would be to insert a gauze swab or pledget soaked with a solution of adrenaline (1:10,000) and lidocaine (4%) into the nasal cavity. This should be left in place for approximately 10-15 minutes before removal. Following the removal, an attempt can be made to cauterize any bleeding point.

If the above measures prove ineffective, it would be appropriate to consider inserting a nasal pack such as a ‘rapid rhino’ pack or alternatively using ribbon gauze soaked in an oily paste like bismuth iodoform paraffin paste. At this stage, it is advisable to refer the patient to the on-call ENT specialist.

Sialolithiasis is a medical condition characterized by the formation of a calcified stone, known as a sialolith, within one of the salivary glands. The submandibular gland, specifically Wharton’s duct, is the site of approximately 90% of these occurrences, while the parotid gland accounts for most of the remaining cases. In rare instances, sialoliths may also develop in the sublingual gland or minor salivary glands.

BPPV is a condition where dizziness and vertigo occur suddenly when the position of the head is changed. This is a common symptom of benign paroxysmal positional vertigo, which is characterized by episodes of vertigo triggered by head movements.

Further Reading:

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo, characterized by sudden dizziness and vertigo triggered by changes in head position. It typically affects individuals over the age of 55 and is less common in younger patients. BPPV is caused by dysfunction in the inner ear, specifically the detachment of otoliths (calcium carbonate particles) from the utricular otolithic membrane. These loose otoliths move through the semicircular canals, triggering a sensation of movement and resulting in conflicting sensory inputs that cause vertigo.

The majority of BPPV cases involve otoliths in the posterior semicircular canal, followed by the inferior semicircular canal. BPPV in the anterior semicircular canals is rare. Clinical features of BPPV include vertigo triggered by head position changes, such as rolling over in bed or looking upwards, accompanied by nausea. Episodes of vertigo typically last 10-20 seconds and can be diagnosed through positional nystagmus, which is a specific eye movement, observed during diagnostic maneuvers like the Dix-Hallpike maneuver.

Hearing loss and tinnitus are not associated with BPPV. The prognosis for BPPV is generally good, with spontaneous resolution occurring within a few weeks to months. Symptomatic relief can be achieved through the Epley maneuver, which is successful in around 80% of cases, or patient home exercises like the Brandt-Daroff exercises. Medications like Betahistine may be prescribed but have limited effectiveness in treating BPPV.

Differentiating between the various causes of vertigo can be challenging, but there are several clues in the question that can help determine the most likely cause. If the patient has a history of sudden and severe vertigo following a viral infection, the diagnosis is likely to be vestibular neuritis or labyrinthitis. Labyrinthitis, which is characterized by hearing loss and tinnitus, is more likely in this case. Meniere’s disease, on the other hand, can also cause hearing loss and tinnitus along with vertigo, but it typically has a longer history of gradually worsening hearing loss and does not cause prolonged vertigo attacks.

Here are the key clinical features of the different causes of vertigo mentioned in the question:

Vestibular neuronitis:
– Infection of the 8th cranial nerve, often viral or bacterial
– Usually preceded by a sinus infection or upper respiratory tract infection
– Severe vertigo
– Vertigo is not related to position
– No hearing loss or tinnitus
– Nausea and vomiting are common
– Nystagmus (involuntary eye movement) away from the side of the lesion
– Episodes may recur over an 18-month period

Labyrinthitis:
– Caused by a viral infection
– Can affect the entire inner ear and 8th cranial nerve
– Severe vertigo
– Vertigo can be related to position
– Can be accompanied by sensorineural hearing loss and tinnitus
– Nausea and vomiting are common
– Nystagmus away from the side of the lesion

Benign positional vertigo:
– Mostly idiopathic (unknown cause)
– Can be secondary to trauma or other inner ear disorders
– Provoked by head movement, rolling over, or upward gaze
– Brief episodes lasting less than 5 minutes
– No hearing loss or tinnitus
– Nausea is common, vomiting is rare
– Positive Hallpike maneuver (a diagnostic test)

Meniere’s disease:
– Idiopathic (unknown cause)
– Sensorineural hearing loss
– Hearing loss usually gradually worsens and affects one ear
– Commonly associated with tinnitus
– Vertigo attacks typically last 2-3 hours
– Attacks of vertigo last less than 24 hours
– Sensation of fullness or pressure in the ear(s)
– Nausea and vomiting are common
– Nystagmus away from the side of the lesion

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

To perform the Rinne’s test, the 512 Hz tuning fork is first made to vibrate and then placed on the mastoid process until the sound is no longer heard. Next, the top of the tuning fork is 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 is no longer appreciated on the mastoid. This is because air conduction should be greater than bone conduction.

In cases of conductive hearing loss, the patient will no longer hear the tuning fork once it is no longer appreciated on the mastoid. This suggests that their bone conduction is greater than their air conduction, indicating an obstruction in the passage of sound waves through the ear canal to 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 senses 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 on both the mastoid and outside the external auditory canal is equally diminished compared to the opposite ear. The sound will disappear earlier on the mastoid and outside the external auditory canal compared to the other ear, but it will still be heard outside the canal.

To perform the Weber’s test, the 512 Hz tuning fork is made to vibrate and then 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.

Malignant otitis externa (MOE), also known as necrotizing otitis externa, is a rare form of ear canal infection that primarily affects elderly diabetic patients, particularly those with poorly controlled diabetes.

MOE initially infects the ear canal and gradually spreads to the surrounding bony structures and soft tissues. In 98% of cases, the responsible pathogen is Pseudomonas aeruginosa.

Typically, MOE presents with severe and unrelenting ear pain, which tends to worsen at night. Even after the swelling of the ear canal subsides with topical antibiotics, the pain may persist. Other symptoms may include pus drainage from the ear and temporal headaches. Approximately 50% of patients also experience facial nerve paralysis, and cranial nerves IX to XII may be affected as well.

To confirm the diagnosis, technetium scanning and contrast-enhanced CT scanning are usually performed to detect any extension of the infection into the surrounding bony structures.

If left untreated, MOE can be life-threatening and may lead to serious complications such as skull base osteomyelitis, subdural empyema, and cerebral abscess.

Treatment typically involves long-term administration of intravenous antibiotics. While surgical intervention is not effective for MOE, exploratory surgery may be necessary to obtain cultures of unusual organisms that are not responding adequately to intravenous antibiotics.

The Dix-Hallpike manoeuvre is the primary diagnostic test used for patients suspected of having benign paroxysmal positional vertigo (BPPV). If a patient exhibits nystagmus and vertigo during the test, it is considered a positive result for BPPV. Other special clinical tests that may be used to assess vertigo include Romberg’s test, which helps identify instability of either peripheral or central origin but is not very effective in differentiating between the two. The head impulse test is used to detect unilateral hypofunction of the peripheral vestibular system and can help distinguish between cerebellar infarction and vestibular neuronitis. Unterberger’s test is used to identify dysfunction in one of the labyrinths. Lastly, the alternate cover test can indicate an increased likelihood of stroke in individuals with acute vestibular syndrome if the result is abnormal.

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.

Acute epiglottitis is inflammation of the epiglottis, which can be life-threatening if not treated promptly.

BPPV is a condition where patients experience vertigo and nystagmus. The Dix-Hallpike test is used to diagnose BPPV, and it involves observing torsional (rotary) and vertical nystagmus. Unlike vertigo caused by vestibular neuritis and labyrinthitis, BPPV is not associated with prodromal viral illness, hearing loss, or tinnitus. The episodes of vertigo and dizziness in BPPV usually last for 10-20 seconds, with episodes lasting over 1 minute being uncommon.

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.

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.

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.

Kiesselbach’s plexus, also known as Little’s area, is formed by the connection of four or five arteries. These arteries include the greater palatine artery, anterior ethmoidal artery, superior labial artery, and sphenopalatine artery. Some sources also include the posterior ethmoidal artery as part of the plexus. The greater palatine artery is a branch of the maxillary artery, while the anterior ethmoidal artery is a branch of the internal carotid artery. The superior labial artery and sphenopalatine artery are both branches of the external carotid artery. The posterior ethmoidal artery, if included, is a branch of the ophthalmic artery.

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.

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.

The Dix-Hallpike test is a straightforward examination that can be utilized to verify the diagnosis of benign paroxysmal positional vertigo (BPPV).

To conduct the Dix-Hallpike test, the patient is swiftly brought down to a supine position with the neck extended by the clinician executing the maneuver. The test yields a positive result if the patient experiences a recurrence of their vertigo symptoms and the clinician performing the test observes nystagmus.

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.

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

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.

The CENTOR score is a tool used to assess the likelihood of a patient having a streptococcal infection, which is a common cause of sore throat. It is based on four clinical criteria: presence of tonsillar exudates, tender anterior cervical lymphadenopathy, absence of cough, and history of fever. Each criterion is assigned one point, with a maximum score of four.

In this case, the patient has a sore throat without cough or runny nose, and her temperature is slightly elevated at 37.7°C. The examination reveals redness in the oropharynx and tonsils, but no tender neck or palpable masses. Based on this information, the patient would score one point on the CENTOR score.

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

The FeverPAIN score is a scoring system that is 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, different recommendations are given regarding the use of antibiotics.

If the score is 0-1, it is unlikely to be a streptococcal infection, with only a 13-18% chance of streptococcus isolation. Therefore, antibiotics are not recommended in this case. If the score is 2-3, there is a higher chance (34-40%) of streptococcus isolation, so delayed prescribing of antibiotics is considered, with a 3-day ‘back-up prescription’. If the score is 4 or higher, there is a 62-65% chance of streptococcus isolation, and immediate antibiotic use is recommended if the infection is severe. Otherwise, a 48-hour short back-up prescription is suggested.

The Fever PAIN score was developed from a study that included 1760 adults and children aged three and over. It was then tested in a trial that compared three different prescribing strategies: empirical delayed prescribing, using the score to guide prescribing, and combining the score with the use of a near-patient test (NPT) for streptococcus. The use of the score resulted in faster symptom resolution and a reduction in antibiotic prescribing, both by one third. However, the addition of the NPT did not provide any additional benefit.

Overall, the FeverPAIN score is a useful tool for assessing acute sore throats and guiding antibiotic prescribing decisions. It has been shown to be effective in reducing unnecessary antibiotic use and improving patient outcomes.

Based on his symptoms, the most likely diagnosis is benign paroxysmal positional vertigo. The most suitable initial treatment option for this condition would be the Epley maneuver.

Further Reading:

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo, characterized by sudden dizziness and vertigo triggered by changes in head position. It typically affects individuals over the age of 55 and is less common in younger patients. BPPV is caused by dysfunction in the inner ear, specifically the detachment of otoliths (calcium carbonate particles) from the utricular otolithic membrane. These loose otoliths move through the semicircular canals, triggering a sensation of movement and resulting in conflicting sensory inputs that cause vertigo.

The majority of BPPV cases involve otoliths in the posterior semicircular canal, followed by the inferior semicircular canal. BPPV in the anterior semicircular canals is rare. Clinical features of BPPV include vertigo triggered by head position changes, such as rolling over in bed or looking upwards, accompanied by nausea. Episodes of vertigo typically last 10-20 seconds and can be diagnosed through positional nystagmus, which is a specific eye movement, observed during diagnostic maneuvers like the Dix-Hallpike maneuver.

Hearing loss and tinnitus are not associated with BPPV. The prognosis for BPPV is generally good, with spontaneous resolution occurring within a few weeks to months. Symptomatic relief can be achieved through the Epley maneuver, which is successful in around 80% of cases, or patient home exercises like the Brandt-Daroff exercises. Medications like Betahistine may be prescribed but have limited effectiveness in treating BPPV.

Meniere’s disease is a condition that affects the inner ear and its cause is still unknown. It is believed to occur due to increased pressure and gradual enlargement of the endolymphatic system in the middle ear, also known as the membranous labyrinth.

Further Reading:

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.

The FeverPAIN score is a clinical scoring system that helps determine the likelihood of a streptococcal infection and whether antibiotic treatment is necessary. It consists of several criteria that are assessed to assign a score.

Firstly, if the patient has a fever higher than 38°C, they score 0 or 1 depending on the presence or absence of this symptom.

Secondly, the presence of purulence, such as pharyngeal or tonsillar exudate, results in a score of 1.

Thirdly, if the patient sought medical attention within 3 days or less, they score 1.

Fourthly, if the patient has severely inflamed tonsils, they score 1.

Lastly, if the patient does not have a cough or coryza (nasal congestion), they score 1.

By adding up the scores from each criterion, the FeverPAIN score can help healthcare professionals determine the likelihood of a streptococcal infection and guide the decision on whether antibiotic treatment is necessary. In this particular case, the patient has a score of 4.

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.

The most likely organism responsible for causing this patient’s symptoms is Haemophilus influenzae type B. This is indicated by the patient’s symptoms of fever, sore throat, high-pitched breathing noise during inspiration, and muffled voice. These symptoms are consistent with epiglottitis, which is a severe infection of the epiglottis caused by Haemophilus influenzae type B. This bacterium is known to cause respiratory tract infections, and it is particularly common in young children.

Further Reading:

Epiglottitis is a rare but serious condition characterized by inflammation and swelling of the epiglottis, which can lead to a complete blockage of the airway. It is more commonly seen in children between the ages of 2-6, but can also occur in adults, particularly those in their 40s and 50s. Streptococcus infections are now the most common cause of epiglottitis in the UK, although other bacterial agents, viruses, fungi, and iatrogenic causes can also be responsible.

The clinical features of epiglottitis include a rapid onset of symptoms, high fever, sore throat, painful swallowing, muffled voice, stridor and difficulty breathing, drooling of saliva, irritability, and a characteristic tripod positioning with the arms forming the front two legs of the tripod. It is important for healthcare professionals to avoid examining the throat or performing any potentially upsetting procedures until the airway has been assessed and secured.

Diagnosis of epiglottitis is typically made through fibre-optic laryngoscopy, which is considered the gold standard investigation. Lateral neck X-rays may also show a characteristic thumb sign, indicating an enlarged and swollen epiglottis. Throat swabs and blood cultures may be taken once the airway is secured to identify the causative organism.

Management of epiglottitis involves assessing and securing the airway as the top priority. Intravenous or oral antibiotics are typically prescribed, and supplemental oxygen may be given if intubation or tracheostomy is planned. In severe cases where the airway is significantly compromised, intubation or tracheostomy may be necessary. Steroids may also be used, although the evidence for their benefit is limited.

Overall, epiglottitis is a potentially life-threatening condition that requires urgent medical attention. Prompt diagnosis, appropriate management, and securing the airway are crucial in ensuring a positive outcome for patients with this condition.
