Acute septic arthritis in children.

Background: Acute septic arthritis is a health-care problem in growing children. The aim of the present study was to determine the demographic features, clinical presentation, diagnostic evaluation, treatment and outcome of children suffering from acute septic arthritis.

Methods: Retrospective review of consecutive admissions of children < or =14 years of age with a bacteriologically and/or radiologically confirmed diagnosis of septic arthritis during the 10 year period, January 1997-December 2006 at King Fahad Hospital, King Abdulaziz Medical City was undertaken.

Physician's perceptions of fever in children. Facts and myths.

Objective: To ascertain the knowledge and attitude of physicians, regarding fever in children.

Methods: A self-administered questionnaire was mailed to 600 randomly selected pediatricians, family practice physicians, emergency medicine physicians and general practitioners, who practice in Saudi Arabia. Appropriateness of responses to questions was determined on the basis of current medical literature.

Clinical and brain 18fluoro-2-deoxyglucose positron emission tomographic findings in ethylmalonic aciduria, a progressive neurometabolic disease.

We report a 2-year-old boy with ethylmalonic aciduria and vasculopathy syndrome evaluated by 18fluoro-2-deoxyglucose positron emission tomographic (18FDG PET) brain scan, with intense uptake of 18FDG in the caudate nucleus and putamen bilaterally but with no morphological changes on magnetic resonance imaging (MRI). A repeat 18FDG PET brain scan 1 year later showed a significant bilateral decreased uptake of glucose in the putamen and the head of the caudate nucleus as well as a decreased uptake in the frontal lobes. On MRI, there was atrophy and watershed infarcts in the basal ganglia, explaining the loss of glucose uptake.

18Fluoro-2-deoxyglucose (18FDG) PET scan of the brain in propionic acidemia: clinical and MRI correlations.

The clinical data and the imaging findings of the positron emission tomography (PET) and the magnetic resonance imaging (MRI) studies in five patients, previously diagnosed to have propionic acidemia, were retrospectively reviewed. The patients were all normal at birth. The first clinical signs, typically hypotonia and failure to thrive, appeared during the first 2 years of life.

18Fluoro-2-deoxyglucose (18FDG) PET scan of the brain in type IV 3-methylglutaconic aciduria: clinical and MRI correlations.

The clinical, 18fluorodeoxyglucose positron emission tomography (18FDG PET) and the magnetic resonance imaging (MRI) brain scan characteristics of four patients diagnosed to have 3-methylglutaconic aciduria were reviewed retrospectively. The disease has a characteristic clinical pattern. The initial presentations were developmental delay, hypotonia, and severe failure to thrive.
