Spermatic granuloma of the vas deferens is a common complication of vasectomy which has received scant morphologic study. This study investigated the light and electron microscopic structure of such granulomas detected in rhesus monkeys (Macaca mulatta) and man after various modes of vasectomy and postoperative periods. Unilateral experimental vasectomy in monkeys was performed by either silk ligation or clasp occlusion; in 4 of 13 ligated animals and 5 of 5 clasp vasectomized animals granulomas developed at the site of fasectomy. ⋯ Spermiophagic cells included macrophages, epithelioid cells, and, in the monkey only, neutrophils. Lymphocytic invasion was a common feature of the human granulomas but was found only occasionally in the monkey granulomas. As a greater number of granulomas are studied in humans and monkeys, it is hoped that the processes underlying granuloma formation and the role of such granulomas in the development of complications after vasectomy will be clarified.

A case of polypoid granulomatous and sclerosing endophlebitis of the spermatic cord due to Schistosoma hematobium is described. The lesion was not due to deposition of ova and is believed to have resulted from death of an incarcerated worm mass upstream. As such, the case represents a hitherto unknown form of schistosomal funiculitis. Vascular changes in schistosomiasis are reviewed and a clinicopathologic classification of schistosomal funiculitis is proposed.

Information concerning normal concentrations of serum sodium, potassium, chloride, and sulfate as well as clinically useful data concerning absorption and excretion of these physiologically important ions are reviewed. Clinical approaches to diagnosis of these electrolyte disturbances are summarized with special emphasis on interpretation and treatment of some of these disorders in children.

Transurethral fulguration of bladder diverticulum (TUFD) is a new and simple procedure. Since July, 1975, 17 patients have had TUFD at the time of transurethral resection of the prostate. Cystograms have been obtained from one week to twelve months after surgery. The diverticulum has shrunk in 9 cases and has totally disappeared in 5; follow-up is incomplete in 3 cases.
