摘要:

A total of 489 consecutive 24-hour urine collections from 162 patients were analyzed for creatinine excretion. The 24-hour creatinine excretion increased with the urine volume. Creatinine excretions in 24-hour urine collections were not statistically different between in- and out-patients. The results indicate that the mean urine creatinine per 24 hours is 1.08 g for 24-hour urine volumes between 500 and 1500 ml. For urine volumes > 1500 ml it is 1.22 g. For 24-hour urine volumes < 500 ml, the mean creatinine is 0.63 g.

摘要:

Despite efforts toward regional planning of maternity services and consolidation of small hospital units, the number of US hospitals with maternity services has increased every year since 1973. Only 2 states have significantly reduced the number of hospitals performing < 500 deliveries annually. The average number of annual deliveries per hospital is 728. No state has achieved an average number of deliveries as high as the 1500 deliveries called for in national guidelines for health planning.

摘要:

The fetoplacental allograft and the malignant neoplasm represent the only 2 biologic conditions in which antigenic tissue is tolerated by a seemingly intact immune system. Recent investigations in the fields of tumor and pregnancy immunology have resulted in the recognition of a variety of immunologic mechanisms which are common to both systems. These common denominators are reviewed and a thesis suggesting a common mechanism in the non-rejection of pregnancy and malignancy, based on the presence of embryogenic antigens in both systems, is presented.

摘要:

A new and easy technique for handling and applying a split-thickness skin graft to the vulva is described. The use of petrolatum gauze backing and application with the skin stapler, as well as postoperative management, are discussed.

摘要:

Human amnion is a readily available and inexpensive allograft with low antigenicity, high antimicrobial potential, and the ability to foster epithelialization. It has been used to reconstruct the vagina in 2 patients following vaginectomy for diffuse carcinoma in situ (CIS) and in 1 patient following severe, corrosive, vulvovaginal burns. It was also used to construct the vagina in 1 patient with müllerian agenesis. In all 4 cases, epithelialization was complete within 8 weeks.

摘要:

Contact hysteroscopy is a new endoscopic technique that allows direct examination of the uterine cavity. The procedure is performed using ambient room light, which is collected by a special light trap incorporated into the body of the instrument. The mechanism for gathering and transmitting light eliminates the need for any electric connections whatsoever. The optical design enables the examiner to see the endocervix and endometrium even in the presence of bleeding. Neither gas nor liquid media are required for observations since the uterine cavity is not distended. An initial appraisal of 80 women with the contact hysteroscope proved successful from the standpoint of technical simplicity, diagnostic accuracy, and absence of complications.

摘要:

Three cases of myasthenia gravis in pregnancy are presented. In 2 cases there were moderately severe hypertension or preeclampsia and difficulty in controlling the myasthenia symptoms. The other case was uncomplicated. The possible relationship between myasthenia gravis and preeclampsia is discussed.

摘要:

Two cases of recurring “pregnancy tumors” are described. The likelihood of these lesions occurring and recurring following conservative therapy is enhanced by hormonal concentrations in the gingival tissues in conjunction with local factors produced by poor oral hygiene. This condition may pose a clinical problem in the pregnant woman.

摘要:

A case of severe postpartum hemorrhage is reported. Three separate surgical procedures failed to reveal the source of bleeding, and standard surgical techniques, including bilateral ligation of the hypogastric arteries, were unsuccessful in producing hemostasis. However, angiography successfully identified the specific bleeding vessel, and transcatheter embolization with Gelfoam fragments quickly and effectively stopped the hemorrhage. The authors consider angiographic embolization to be an effective alternative approach to the control of pelvic hemorrhage and recommend that the technique be considered prior to surgical intervention.
