Background. The Miami modification of the traditional Wertheim-Meigs radical hysterectomy was used to treat Stage IB-IIA cervical cancer in a 25-year prospective study involving 978 patients.The modifications included vaginal reconstruction and closure using bladder and rectosigmoid serosa, retroperitoneal drainage through abdominal suction catheters, and suspension of the denuded ureters with the ipsilateral obliterated hypogastric artery.Results. The overall corrected 5-year survival rate was 90.19'0, with a surgical mortality rate of 1.4% and an overall urinary fistula rate of 1.4%. This fistula rate was significantly better than a 4.4% incidence rate in a literature survey. Although not measured, the Miami modification appeared to lengthen the vagina.Therefore, it was concluded that radical hysterectomy with the Miami modifications can be done safely in most patients with Stage IB-IIA cervical cancer.

The primary goal in this study was to examine maternal support of numerical concepts at 36 months as predictors of math achievement at 4½ and 6-7 years. Observational measures of mother-child interactions (n = 140) were used to examine type of support for numerical concepts. Maternal support that involved labeling the quantities of sets of objects was predictive of later child math achievement. This association was significant for preschool (d = .45) and first-grade math (d = .49), controlling for other forms of numerical support (identifying numerals, one-to-one counting) as well as potential confounding factors. The importance of maternal support of labeling set sizes at 36 months is discussed as a precursor to children's eventual understanding of the cardinal principle.

Background. Data analysis of the recent National Survey of Ovarian Carcinoma revealed significant differences in patterns of care among various physician specialists. The goal of this study was to determine if different care patterns led to differences in patient survival. Methods. Data were collected from 25 consecutive patients with ovarian cancer diagnosed in 1983 and 1988 from 1230 hospitals with cancer programs across the United States. Results. A total of 12,316 patients from 904 hospitals were registered, of whom 20.8% were cared for by gynecologic oncologists (GYO), 45.0% by obstetrician‐gynecologists (OBG), and 21.1% by general surgeons (GS). GYO preferred the upper‐lower midline incision in 44.1% of patients, whereas both OBG and GS chose the low midline approach in 44–45%. GYO performed more hysterectomies, oophorectomies, omentectomies, and lymph node and peritoneal biopsies than did other specialists. Although the rates of surgery of the small intestine were comparable between GYO and GS, the latter performed significantly more colostomies and resections of the large intestine. The optimal debulking rates were: GYO, 42–45%; OBG, 40–44%; and GS 25%. There was no significant survival difference between patients cared for by GYO and those cared for by OBG for all stage divisions. However, with the exception of patients with Stage I disease, patients cared for by GS had significantly reduced survival than did those cared for by GYO and OBG (P < 0.004). Conclusion. Efforts must be made to ensure that more patients with ovarian cancer are cared for by physicians in the appropriate specialties.

Background. An analysis was conducted by the American College of Surgeons Cancer Commission evaluating the patterns of care of ovarian cancer patients diagnosed in 1983 and 1988. The purpose of this study was to investigate whether there was a difference in the care patterns of elderly ovarian cancer patients and its impact on survival. Methods. Data were collected from 25 consecutive patients whose disease was diagnosed initially at 904 participating hospitals with cancer programs in 1983 and 1988. The survival and care of patients greater than or equal to 80 years of age were compared to those less than 80 years of age. Results. Of the 12,316 patients evaluated, 1,115 were 80 years or older. A significant reduction in survival was noted among patients 80 years and older as compared to their younger counterparts (P = 0.03–0.00001). The 5‐year survivals were: stage I, 89% versus 79%; stage II, 58% versus 40%; stage III, 25% versus 11%; and stage IV, 13% versus 3%, respectively, for those less than 80 years old as compared to those greater than or equal to 80 years old. Most elderly ovarian cancer patients were cared for by nononcologists such as general surgeons (31%) and obstetricians/gynecologists (29%). As a group, older patients had fewer total abdominal hysterectomies, bilateral salpingo‐oophorectomies, and omentectomies than their younger counterpart (P < 0.00001). As further evidence for a less aggressive surgical approach, the optimal tumor debulking rates of women greater than or equal to 80 years were significantly less than those of younger patients (P < 0.001). There was no significant increase in anesthesia complications between age groups. Generally, older patients are less likely to receive adjuvant chemotherapy than younger patients (42% versus 69%, P < 0.0001). Conclusion. It appears that conservative treatments contributed to the decreased survival of older ovarian cancer patients.

Night work increases diabetes risk. Misalignment between the central circadian "clock" and daily behaviors, typical in night workers, impairs glucose tolerance, likely due to internal misalignment between central and peripheral circadian rhythms. Whether appropriate circadian alignment of eating can prevent internal circadian misalignment and glucose intolerance is unknown. In a 14-day circadian paradigm, we assessed glycemic control during simulated night work with either nighttime or daytime eating. Assessment of central (body temperature) and peripheral (glucose and insulin) endogenous circadian rhythms happened during constant routine protocols before and after simulated night work. Nighttime eating led to misalignment between central and peripheral (glucose) endogenous circadian rhythms and impaired glucose tolerance, whereas restricting meals to daytime prevented it. These findings offer a behavioral approach to preventing glucose intolerance in shift workers.
