Epithelial tumors of the ovary in women less than 40 years old

From Jan 1, 1978 through Dec 31, 1983, 64 patients with epithelial ovarian tumors, frankly malignant or borderline, were managed at one institution. Nineteen patients (29.7%) were under age 40. The youngest patient was 19 years old. Nulliparity was present in 32% of this group of patients. Of these young patients, 58% had borderline epithelial tumors, compared to 13% of patients over 40 years of age. Twenty-one percent of the young patients were initially managed by unilateral adnexal surgery. The overall cumulative actuarial survival rate of all young patients was 93%. Young patients with epithelial ovarian tumors tend to have earlier grades of epithelial neoplasms, and survival is better than that reported for older patients with similar tumors.

Effect of feeding-tube properties on residual volume measurements in tube-fed patients

BACKGROUND: The effect of feeding tube size and port configuration on the ability to measure gastric residual volume (GRV) is poorly understood. In addition, there is confusion about the need to measure GRVs during feedings into the small bowel. This study sought to (1) compare the volume of gastric contents obtained from small-diameter feeding tubes and large-diameter sump tubes concurrently positioned in the stomach and (2) describe the distribution of GRVs during small-bowel feedings. METHODS: For the first objective, GRV measurements were made from 10-Fr tubes (n = 645) and 14-Fr or 18-Fr sump tubes (n = 645) concurrently present in 62 critically ill patients. Sixty-milliliter syringes were used to measure GRVs from the 10-Fr tubes; the fluid was returned to the stomach and measurements were repeated from the large-diameter sump tubes. To address the second research objective, 890 GRV measurements were made from 14-Fr or 18-Fr gastric sump tubes (not connected to suction) in 75 critically ill patients who were receiving small-bowel feedings. RESULTS: When GRVs were >50 mL, a linear regression equation indicated that volumes obtained from the large-diameter sump tubes were about 1.5 times greater than those obtained from the small-diameter tubes concurrently present in the stomach, p < .001. Gastric volumes > or =100 mL were found in 11.6% of the 890 measurements made in patients receiving small-bowel feedings; volumes > or =150 mL were found in 5.4% of the measurements. CONCLUSIONS: The findings suggest that GRVs obtained from large-diameter sump tubes are about 1.5 times greater than those obtained from 10-Fr tubes. Large GRVs occur in at least 5% of patients receiving postpyloric feedings.     

Have we met the educational challenges of obstetrics and gynecology? A response to the Association of Professors of Gynecology and Obstetrics Initiative of 1986

OBJECTIVE: The purpose of this study was to assess the progress that has been made toward meeting the educational challenges in obstetrics and gynecology that were made at an Association of Professors of Obstetrics and Gynecology special forum in 1986. STUDY DESIGN: We placed the five major issues and specific problems that were identified within the context of developments that have occurred in medical education, the Association of Professors of Obstetrics and Gynecology, and the specialty over the last 15 years. We used the medical education literature and the accomplishments of the members of the Association of Professors of Obstetrics and Gynecology to measure progress. RESULTS: Many of the challenges that were raised at the original forum remain. Significant progress, much of it spearheaded by the Association of Professors of Obstetrics and Gynecology, has been made in the areas of teaching methods and skills, evaluation techniques, faculty development, computer usage, teaching recognition, counseling for the fourth-year student, and an integrated curriculum in women's health. CONCLUSION: Progress has occurred within the context and demands of a changing health care system that constricts the time and funding that are available for medical education.     

Overuse injuries in youth sports: biomechanical considerations

Many children today participate in highly organized sports programs that involve regimented year-round repetitive training. This type of training has led to an increased incidence of overuse musculoskeletal injuries. Sports physicians have dealt with sports injuries in children for many years and, on the basis of their clinical experience, have developed guidelines to treat and to try and prevent these injuries. The purpose of this article is to provide a biomechanical perspective of sports injuries in young athletes and blend ideas from this perspective with more traditional clinical perspectives that dominate the literature relative to this topic. Basic tissue and gross movement mechanics principles are used to identify growth, morphological, and movement factors that may predispose a child to an overuse injury. Several biomechanical analyses of simple movement tasks are presented to quantify the forces developed in various tissues and to illustrate the effects that growth can have on these forces. Guidelines are given for developing injury prediction models that may be used in the future to establish safe and effective training guidelines for children.
