This report describes the clinical course of a child who had excision of several symptomatic cavernous hemangiomas. Disseminated intravascular coagulation resulted in severe postoperative bleeding. DIC was treated successfully with heparin.
The therapeutic effect of local infiltration of the testis by testosterone crystalline suspension was studied in 18 cases of severe oligozoospermia. Evaluation was done by semen analysis follow-up, and results were correlated with preoperative testicular biopsies. About 40% of the cases showed improvement of sperm count and/or motility. Testicular biopsies of responding cases showed mild inhibitory changes, such as sloughing or partial spermatogenic arrest at late stages, while cases with tubular hyalinization or spermatogenic arrest at the stage of spermatogonia showed no response. The method proved to be simple, safe, and promising.
A comparative study of hysterosalpingography (HSG) and laparoscopy in the investigation of infertility is presented. From 1973-1977, 352 cases were investigated with both HSG and laparoscopy. In 57.67% of the cases there was complete agreement between HSG and laparoscopy. The study included 168 cases of unexplained infertility and 184 cases with abnormal hysterosalpingographic findings. Pelvic adhesions were demonstrated in 151 cases by laparoscopy as compared to 76 cases in which its presence was only suspected by HSG. Laparoscopy revealed a 57.14% of associated pelvic pathology in cases of unexplained fertility. The present study concludes that laparoscopy as compared to HSG is not only more informative, but also more accurate and conclusive.
Fifty-two infertile men with varicoceles were subjected to bilateral testicular biopsy to detect the effect of the varicocele on each testis. The results indicate that varicocele can result in infertility primarily through sloughing of immature cells or through arrest of spermatogenesis at the spermatid or primary spermatocyte stage. The effect is bilateral but is more marked on the varicocele side. However, the presence of a varicocele could not explain the infertility of seven men with normal biopsies and of four men with a normal biopsy on the varicocele side and arrest on the other side.
Postoperative nasogastric suction is not a necessary complement to elective colon resection. We studied two groups of patients who had elective colon resection: nasogastric suction was used in the postoperative management of 53 patients, while 23 patients were managed without nasogastric suction. The morbidity and mortality rates were comparable in the two groups.
A thin-layer chromatography technique was used to study the arginine metabolism of Mycoplasma meleagridis. The technique reflected the enzyme activity of the dihydrolase pathway through detection of readily visible end products on X-ray film. Strains of M. meleagridis differing in their pathogenicity for turkeys did not vary in arginine metabolism. In addition, no significant difference was observed in plasma arginine concentrations between M. meleagridis-infected and uninfected poults. It was concluded that the pathogenesis of M. meleagridis infection in turkeys was not based on its competition with the host for arginine.
A safe and effective way to prevent the development of hypoglycaemia in young children during general anaesthesia is to give drinks sweetened with maltose 2 hours before operation. Metoclopramide (Maxolon) is injected intramuscularly to hasten absorption. The postoperative blood sugar in the maltose-treated group (28 patients) was 100+/-22-21 mg/ml (5-5+/-1-232 mmol/litre) and significantly higher ( P less than 0-0005) than in the starved group (22 patients).
Following is a report and a review of literature concerning the supernumerary ovary. Up to now only 7 cases have been reported, and our case appears to be the eighth. The anatomic situation in this case was unusual since it was found in the mesentery. Of the cases previously reported, 2 have been associated with benign cystic teratoma.

A case report of acute peroneal compartment syndrome occurring in a 25-year-old male softball player is presented, in which neuropraxia of the common peroneal nerve occurred within 8 hr after onset and in which complete recovery occurred after fasciotomy was done 13 hr after onset of symptoms. A plea is made for early diagnosis and complete fasciotomy carried out as a surgical emergency. This must be accomplished if results previously reported, indicating permanent disability in 80%, are to be improved.
The three-dimensional structure of Mycoplasma meleagridis strain RY-39A was studied by scanning-electron microscopy. The morphologic forms observed between 12 hours and 7 days suggest that the organism undergoes a sequential metamorphosis in its development. Single rounded forms in lag phase give rise to larger cells and filaments in the log phase, which fragment into coccus forms in the late stationary phase.
