Clinical Experience With Pharmacological Venous Thromboembolism Prophylaxis in the Underweight and Critically Ill.

Background: The optimal regimen for pharmacological prophylaxis of venous thromboembolism (VTE) in underweight, critically ill patients is unknown.

Objective: To describe prescribing patterns for VTE prophylaxis in underweight (≤50 kg or body mass index ≤18.5 kg/m(2)), critically ill patients and identify the prevalence of VTE and bleeding.

Atypical fibroxanthoma: Case series of 16 patients.

Atypical fibroxanthoma is an unusual tumour of skin seen mainly in the head and neck region of elderly patients. Clinically it appears as red, ulcerated nodules, which can be difficult to differentiate from other tumours without histopathological examination. Immunohistochemical analysis also aids diagnosis.
