During April 2013 in China, mild respiratory symptoms developed in 1/61 workers who had culled influenza A(H7N9) virus-infected poultry. Laboratory testing confirmed A(H7N9) infection in the worker and showed that the virus persisted longer in sputum than pharyngeal swab samples. Pharyngeal swab samples from the other workers were negative for A(H7N9) virus.

The goal of mechanistic case diagraming (MCD) is to provide students with more in-depth understanding of cause and effect relationships and basic mechanistic pathways in medicine. This will enable them to better explain how observed clinical findings develop from preceding pathogenic and pathophysiological events. The pedagogic function of MCD is in relating risk factors, disease entities and m...

We conducted a study to determine whether clinical algorithms would be useful in malaria diagnosis among people living in an area of moderate malaria transmission within Kilifi District in Kenya. A total of 1602 people of all age groups participated. We took smears and recorded clinical signs and symptoms (prompted or spontaneous) of all those presenting to the study clinic with a history of fe...

A case of recurrent orbital myositis presenting with progressive diplopia and strabismus is discussed. The pertinent clinical findings, investigations, treatment and management are presented, with emphasis on the clinical response to corticotherapy.

Frailty is a state of vulnerability that carries an increased risk of poor outcomes in older adults. Common signs and symptoms are fatigue, weight loss, muscle weakness, and progressive decline in function. Frail older adults are among the most challenging for medical management. However, awareness of this syndrome and its risks can help us care for these patients more confidently and decrease ...

The standard management options were developed by a consensus committee and review panel of 26 experts to assist in providing optimal patient care based on the standard classification and grading systems for rosacea that were developed to perform research; analyze results and compare data from different sources; and provide a common terminology and reference for the diagnosis, treatment, and as...

Any surgical procedure involves risks. Thyroid surgery can cause potentially fatal complications during the early post-operative phase. It is essential that nurses have the knowledge and skills to detect early signs and symptoms of potential complications and take appropriate action. Early detection and rapid response are key to maintaining patient safety and minimising harm.
