Intraventricular and brachial artery thrombosis in nephrotic syndrome.

A 23-year-old Saudi female presented with nephrotic syndrome. On renal biopsy she had primary focal and segmental glomerulosclerosis which was resistant to steroids. Two years later she presented with absent left arm pulses and on investigation a diagnosis of left ventricular thrombosis and thromboembolism of left brachial artery was made. Low antithrombin III, high fibrinogen levels and diuretic therapy were the possible causative factors for hypercoagulable state. On anticoagulation therapy initiated with heparin and continued with warfarin for 8 weeks there was complete dissolution of intraventricular and improvement of left brachial artery thrombosis. An early diagnosis and treatment of this potentially serious complication of nephrotic syndrome are stressed.

Bartter's syndrome in two successive generations of a Saudi family.

Bartter's syndrome (BS) is characterized by primary renal tubular hypokalemic metabolic alkalosis, hyperreninemia, hyperaldosteronism and normal blood pressure. The parents and siblings of a BS patient were evaluated for renal tubular function. The father and all 9 siblings of the patient had biochemical features of BS. His mother, a first cousin of his father, had hypokalemia and hyperkaluria but no other features of BS and could have been a 'carrier'. The mother and all 9 siblings were asymptomatic. Including the patient, hypomagnesemia was present in 8 of 12 family members. Therapy with a combination of potassium chloride and magnesium increased the serum potassium and magnesium levels to within normal limits. The familial occurrence in BS is well known, and reports of the disorder in siblings and the first generation of children of consanguineous marriages and normal parents have been taken to suggest an autosomal recessive inheritance. One affected parent and involvement of all siblings of the patient raise the possibility of an autosomal dominant inheritance in the present family.

Anatomic considerations for anterior approaches to the ulna.

Anterior approaches to the ulna were studied on 22 cadaveric forearms as alternative approaches to the ulnar shaft. An anterior approach is indicated when there is extensive posterior scar tissue, or extensive soft tissue loss in the posterior forearm as in some fresh fractures, or when a tumor is resected from the anterior ulna. This study describes and compares the traditional anteromedial approach to the ulna with a proposed anterior approach, and defines the exact relations of the different anatomic structures seen in each approach.
