Eclampsia: a pediatric neurologic problem.

Eclampsia is a syndrome of hypertension, proteinuria, edema, and neurologic manifestations such as seizures, focal deficits, or blindness occurring during pregnancy, mainly in primigravidas. Although it is not seen often in the pediatric population, it occurs with greater frequency among pregnant patients under the age of 15 than in the general population. Serious sequelae can be prevented with prompt and adequate treatment, including termination of pregnancy.

Chronic renal failure presenting as proximal muscle weakness in a child.

A 13-year old boy presented with a three-year history of slowly progressive proximal muscle weakness, particularly involving the lower extremities. Chronic renal failure was uncovered in the course of his evaluation. Urologic investigation showed small and poorly functioning kidneys with a BUN of 118 mg/dL and a creatinine of 10.7 mg/dL. There were no anomalies of the proximal or distal collecting systems or history suggestive of recurrent urinary tract infection. The neurologic examination revealed proximal muscle weakness primarily of the lower extremities and especially of the proximal musculature of the pelvic girdle. Nerve conduction studies were normal. The electromyogram (EMG) showed high-voltage polyphasic potentials consistent with neurogenic muscle disease. A biopsy of the right quadriceps muscle demonstrated type II muscle fiber atrophy with histochemical staining. The patient's clinical findings, EMG studies, and muscle biopsy were not specific for either neurogenic or myopathic disease. Following a period of home peritoneal dialysis and renal transplantation, there was significant clinical improvement of the muscle weakness.
