Two-Gene Panel Differentiates between Pediatric Bacterial and Viral Infections

A two-gene panel was shown to differentiate between viral and bacterial infections in children with fevers with 95-100% accuracy.

Since clinical features do not reliably distinguish bacterial from viral infection, many children worldwide receive unnecessary antibiotic treatment, while bacterial infection is missed in others. To solve this problem, investigators at Imperial College London (United Kingdom) sought to identify a blood RNA expression signature that could distinguish bacterial from viral infection in febrile children.

Steam Inhalation Does not Ease Chronic Nasal Congestion

While steam inhalation is widely adopted in an attempt to ease a blocked nose, a new study suggests it is unlikely to work for chronic nasal congestion.

However, saline nasal irrigation - a technique used to "flush out" excess mucus from the nasal cavity - may be beneficial for chronic nasal congestion, according to the researchers.

Study leader Dr. Paul Little, professor of primary care research at the University of Southampton, United Kingdom, and colleagues recently published their findings in the Canadian Medical Association Journal.

Nasal congestion is a common complaint, often caused by the common cold, flu, or sinus infection. Hay fever and other allergies, nasal polyps, and chronic sinusitis are some other causes of the condition.

While nasal congestion is just an irritation for the most part, it can cause other symptoms, such as headaches and blurred vision.
