Associations of blood pressure with body composition among Afro-Caribbean children in Barbados.

Unlabelled: Despite complex presentation of adult hypertension and a concomitant obesity epidemic, little is known about overweight in relation to blood pressure among Caribbean children. We examined blood pressure in relation to body size in a cross-sectional study of 573 Barbadian children aged 9-10 years (2010-2011). The United States normative blood pressure percentiles were used to identify children with high (≥95th percentile) or high normal blood pressure (90th-95th percentile).

C-Kit-positive metastatic malignant pigmented clear-cell epithelioid tumor arising from the kidney in a child without tuberous sclerosis.

We report the first pediatric case of malignant pigmented epithelioid clear-cell tumor arising from kidney; the lesion occurred in a 12-year-old girl without tuberous sclerosis. The tumor was widely metastatic to the retroperitoneum and chest, and the patient died of the disease 9 months after diagnosis, despite active chemotherapy. Pigmented epithelioid clear-cell tumor of the kidney is a rare variant of epithelioid angiomyolipoma and a member of the family of perivascular epithelioid cell tumors (PEComas).

Sporadic Creutzfeldt-Jakob disease mimicking variant Creutzfeldt-Jakob disease.

Background: The determination of the form of prion disease and early diagnosis are important for prognostic, public health, and epidemiologic reasons.

Objective: To describe a patient with sporadic Creutzfeldt-Jakob disease (sCJD) who had a clinical history and initial electroencephalogram and magnetic resonance imaging findings consistent with variant CJD (vCJD).

Results: Results of a repeated electroencephalogram were suggestive of sCJD, and a subsequent brain biopsy confirmed this diagnosis.
