Summary
Rhinovirus (RV) is the most common virus found in middle ear effusions (MEE) of children with otitis media with effusion (OME). Frequent ear infections, early onset, and family allergy history increase the risk of RV detection in MEE.
Area of Science:
- Pediatrics
- Infectious Diseases
- Otolaryngology
Background:
- Frequent viral upper respiratory tract infections (URTI) are linked to otitis media with effusion (OME).
- Atopy is associated with both OME and viral infections, suggesting potential interactions.
Purpose of the Study:
- To identify viruses in middle ear effusions (MEE) of children aged 2-7 with OME.
- To determine risk factors for virus detection in MEE.
Main Methods:
- Middle ear effusion (MEE) samples from 37 children with OME were analyzed.
- Reverse transcription PCR (RT-PCR) was used to detect viral RNA.
- Physical examination, skin prick tests, and allergy questionnaires were administered.
Main Results:
- Rhinovirus (RV) was detected in 40.5% of MEE samples; enterovirus was found in one sample.
- RV detection was higher in children with frequent OME episodes, early onset (<2 years), and a family history of allergy.
- No significant differences were observed in other examined parameters between groups.
Conclusions:
- Rhinovirus is the predominant virus in the middle ear of children with OME, particularly those with recurrent or longstanding OME or allergic predisposition.
- Interactions between allergy and RV infections may contribute to the development of middle ear disease.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
01:16Drugs Used in Upper Respiratory Disorders: Overview
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

01:29Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:27Influenza
Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...
01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
