Based on the clinical scenario, the most likely underlying pathogen is the Epstein Barr virus (EBV).An Epstein Barr virus (EBV) infection most commonly results in upper respiratory tract symptoms with fever and sore throat. Lymphadenopathy is frequently palpable on examination. Splenomegaly may also occur, and for this reason, patients diagnosed with glandular fever should be advised to avoid contact sports for one month following diagnosis. The presence of petechiae on the soft palate is also associated with EBV infection. The vast majority of patients with active EBV infection will develop a widespread rash if given amoxicillin, therefore, phenoxymethylpenicillin (Penicillin V) is recommended for the treatment of a suspected bacterial throat infection to prevent this complication occurring for individuals who have EBV infection.Other options:- Coronavirus: This is one of the causes of the common cold and is frequently responsible for sore throats; however, in this case, the presenting features are more suggestive of an EBV infection.- Group A Streptococcus: Streptococci are classified into two main groups; alpha-haemolytic and beta-haemolytic. Group A Streptococcus belongs to the beta-haemolytic group. Group A streptococcal infection is a common cause of bacterial tonsillitis. It is possible that the child, in this case, had streptococcal tonsillitis and has had a drug reaction to the amoxicillin. However her age, flu-like symptoms and petechiae on her palate all point to an EBV infection and amoxicillin resulting in a rash.- Parainfluenza: Parainfluenza viruses are one of many causes of the common cold and can cause pharyngitis. They are the leading cause of viral croup.- Rhinovirus: Rhinoviruses are one of many causes of the common cold and are frequently responsible for sore throats; however, in this case, are other factors suggesting EBV infection.

Give up to five back blows: hit them firmly on their back between the shoulder blades. Back blows create a strong vibration and pressure in the airway, which is often enough to dislodge the blockage.

Grommets are small tubes surgically inserted into the tympanic membrane to drain viscous inflammatory fluid found in the middle ear in bilateral otitis media with effusion of more than three months duration. There is no indication against using in ear headphones or flying. Swimming or snorkelling can be reinforced with ear plugs. However immersion of the child’s head in soapy water is to be avoided as the water is more likely to enter the ear.

Not uncommonly, children insert a foreign body in their ear canal and do not mention it to their parents. If any pain accompanies purulent drainage, the possibility of a foreign body in the ear canal should be considered. A patient with a foreign body in place will not improve until it is removedOrganic foreign bodies tend to elicit inflammatory reactions. In the ear, they predispose to otitis externa, suppurative otitis media and hearing loss

With children nosebleeds often occur after nose picking and are benign in nature. For active bleeding, pressing of soft parts of the nose is required to stop the bleeding before doing anything else.

The child has Chronic suppurative otitis media (CSOM) which is defined as a perforated tympanic membrane with persistent drainage from the middle ear for more than 2-6 weeks.CSOM differs from chronic serous otitis media in that chronic serous otitis media may be defined as a middle ear effusion without perforation that is reported to persist for more than 1-3 months. Patients with chronic suppurative otitis media (CSOM) present with a draining ear of some duration and a premorbid history of recurrent acute otitis media, traumatic perforation, or the placement of ventilation tubes. Typically, they deny pain or discomfort. A common presenting symptom is hearing loss in the affected ear. Reports of fever, vertigo, and pain should raise concerns about infratemporal or intracranial complications. A history of persistent CSOM after appropriate medical treatment should alert the physician to consider cholesteatoma.The external auditory canal may or may not be oedematous and is not typically tender. The discharge varies from fetid, purulent, and cheese like to clear and serous. Granulation tissue is often seen in the medial canal or middle ear space. The middle ear mucosa visualized through the perforation may be oedematous or even polypoid, pale, or erythematous.

When a child does not hear the sound in the middle during Weber test, it means they either they have a conductive hearing loss on the side they hear the sound, or a sensorineural hearing loss on the opposite side. Rinne’s test helps distinguish between the two. In this particular case, the hearing loss is most probably conductive due to the middle ear effusion. Therefore, Weber’s test should be localised to the left and Rinne’s should be positive on the right.

Based on the clinical scenario, the most probable diagnosis for this patient is maxillary sinusitis.The maxillary sinus drains from its superior aspect, leaving it prone to infections. It is the most commonly affected sinus in sinusitis.Common symptoms of maxillary sinusitis include postnasal discharge, pain, headache and toothache.Radiological imaging may show a fluid level in the antrum.Common organisms causing maxillary sinusitis include Haemophilus influenzae or Streptococcus pneumoniae.Treatment with antral lavage may facilitate diagnosis and relieve symptoms. Antimicrobial therapy has to be continued for long periods. Antrostomy may be needed.Other options:- Frontal sinusitis more commonly causes intracranial complications, but it is still less frequent than maxillary sinusitis.- The petrosal sinus is not a cavity within bone; rather, it is a venous structure located beneath the brain.- Frontoethmoidal sinusitis: It usually presents with frontal headache, nasal obstruction and altered sense of smell. Inflammation may progress to involve periorbital tissues. Ocular symptoms may occur, and secondary CNS involvement brought about by infection entering via emissary veins. CT scanning is the imaging modality of choice. Early cases may be managed with antibiotics. More severe cases usually require surgical drainage.

At least seven episodes in the previous year, five episodes in each of the previous two years, or three episodes in each of the previous three years are indications for tonsillectomy. Antibiotics should be administered in the conventional dosage for proved or suspected streptococcal episodes. For now the child should be treated on a case by case basis.

Stridor is a sign of upper airway obstruction. One of the most common causes of stridor in children is laryngomalacia. In the absence of laryngomalacia, stridor presenting with respiratory distress, few chest signs and no preceding coryza symptoms or fever all point to the inhalation of a foreign object. This is common in children, with a peak incidence between 1 and 2 years of age. This child did not present with a high temperature, usually indicative of epiglottitis . The incidence of epiglottis has decreased due to the H. Influenza type b vaccine. Additionally viral croup and bronchiolitis present with upper respiratory tract infection. Asthma rarely presents with stridor but is rather associated with a wheeze.
