Phase II trials of docetaxel (Taxotere) in advanced ovarian cancer--an updated overview

Docetaxel (Taxotere) has been studied at a dose of 100 mg/m2 i.v. as a one hour infusion every 3 weeks, in four phase II trials in patients with extensively pretreated ovarian cancer. A total of 340 patients were treated, including 256 patients in two separate EORTC (European Organization for Research and Treatment of Cancer) trials and 84 patients in two trials in the U.S.A. All patients had received prior cisplatin or carboplatin therapy and the treatment-free interval was less than 4 months in 155 patients. The overall response rate using conventional UICC criteria was 30% among 315 evaluable cases (95% confidence interval: 24-36%). Among 155 patients whose disease was most refractory (i.e. treatment-free interval was less than 4 months), the overall response rate was 28% (95% confidence interval: 19-36%). Response duration ranged from 4 to 17 months. Grade IV neutropenia was a common finding and fluid retention was observed. The incidence of febrile neutropenia ranged from 8 to 44% of patients with two deaths (i.e. 0.6% of the total treated) related to neutropenic sepsis. Docetaxel and paclitaxel (Taxol) have comparable activities in ovarian cancer. Ongoing studies with docetaxel include its use in patients as part of first-line therapy, as well as in patients refractory to paclitaxel. To prevent the development of fluid retention, these now involve the routine use of steroid prophylaxis. It is expected that docetaxel will prove to be an important addition to the drugs available for the treatment of ovarian cancer.     

Water supplementation of infants in the first month of life

OBJECTIVE: To describe the prevalence of and risk factors associated with regular water supplementation of neonates. DESIGN: Evaluation of data from the Food and Drug Administration's Infant Feeding Practices Study, a panel study of US women of fairly high socioeconomic status who were followed up from late pregnancy through their infants' first year of life. The sample was drawn from a nationally distributed consumer mail panel. Each mother was asked whether she gave her neonate water at least 3 times per week. PARTICIPANTS: A total of 1677 mothers of infants who were neonates in April through November 1993. MAIN OUTCOME MEASURES: Percentages of mothers who gave their neonates water at least 3 times a week, considering infant feeding status, mother's education, and family income. RESULTS: About one fourth (24.7%) of the mothers reported giving their neonates water at least 3 times per week. Stratification by feeding practices and socioeconomic factors revealed that 41.6% of mothers who formula-fed their neonates, 47.4% of mothers with less than a high school education, and 35.4% of mothers with an annual family income less than $22,500 gave their neonates water at least 3 times per week. CONCLUSIONS: Water supplementation of neonates was a prevalent practice in this cohort of women. Feeding practices, maternal education, and family income were all significant risk factors associated with this behavior.     

Resolution of abnormal MR signal intensity in patients with stress fractures of the femoral neck

OBJECTIVE: The purpose of this study was to describe the natural evolution of abnormal MR signal intensity after the diagnosis of a stress fracture of the femoral neck and to ascertain the time to resolution of that abnormal signal intensity. SUBJECTS AND METHODS: Ten patients who had been previously diagnosed with stress fractures of the femoral neck after positive MR scans of the hip were examined with MR imaging at regular intervals. In each patient T1-weighted and short inversion time inversion recovery (STIR) sequences were obtained until the abnormally bright, diffuse MR signal intensity (representing edema) disappeared from the STIR images. Time to resolution was correlated with each patient's age and presence or absence of a fatigue line on MR imaging. Statistical analysis was done using Fisher's exact test. RESULTS: Edema resolved in seven patients within 3 months of initial diagnosis, in two patients within 6 months, and in the remaining patient within 12 months. We found no statistically significant correlation between time to resolution and patient age or the presence of a fatigue line on MR imaging. Residual sclerosis occurred in five patients, all of whom had a fatigue line. Two of these patients developed bright T1 signal (fatty marrow conversion) around the area of sclerosis. In the remaining three patients, STIR images revealed a brightened fatigue line, which we presumed was caused by granulation tissue. CONCLUSION: In this study, 90% of patients showed resolution of abnormal MR signal intensity on STIR imaging within 6 months of the initial diagnosis of stress fracture of the femoral neck. Such data may prove helpful in examining patients with recurrent symptoms who undergo repeated MR scanning. When an abnormally bright, diffuse MR signal intensity on STIR imaging is seen more than 6 months after an original injury, such abnormal signal intensity is likely to represent new injury.     

Cytologic diagnosis of peritoneal fluids. Applicability to the laparoscopic diagnosis of endometriosis

OBJECTIVE: To determine the accuracy of cytologic examination of laparoscopically obtained peritoneal fluid in the diagnosis of endometriosis. STUDY DESIGN: This investigation analyzed 50 laparoscopic fluid specimens received over a three-year period. Retrospective cytologic findings were correlated with clinical history and laparoscopic diagnoses. Touch preparations were also collected from necropsies to develop cytologic criteria necessary to distinguish endometrial cells from mesothelial cells. RESULTS: The presence of hemosiderin-laden macrophages in peritoneal fluids was more specific but less sensitive than the presence of endometrial cells for the diagnosis of endometriosis. CONCLUSIONS: In women undergoing laparoscopy to detect endometriosis, the identification of endometrial cells alone in peritoneal fluids may not be sufficient to render a definitive diagnosis of endometriosis. However, the presence of hemosiderin-laden macrophages in this population should alert the cytologist to that possibility.     

Biochemical studies on combined effects of garlic (Allium sativum Linn) and ginger (Zingiber officinale Rosc) in albino rats

Adult male rats of wistar strain were fed diets containing (w/w) 2% garlic (group II), 0.5% ginger (group III) and a combination of garlic plus ginger (group IV) for 4 weeks to study their effects on serum biochemical parameters. A significant increase in body weight was observed in all groups except that fed ginger (group III). A significant decrease in blood glucose, serum total cholesterol and serum alkaline phosphatase were found in all groups, whereas serum triglycerides were decreased significantly only in group IV. Serum HDL-cholesterol was significantly increased only in groups III and IV. However, HDL-cholesterol, VLDL-cholesterol and atherogenic index were significantly decreased in animals fed with combination of the two, compared to garlic/ginger alone. Hence, a combination of garlic and ginger is much more effective in reducing blood glucose and serum lipids.     

The genetics of alcoholism: 1997

The relationship between trunk muscle morphology as measured on transverse magnetic resonance images and isokinetic lifting, psychophysical lifting, and static back muscle endurance testing was examined in 110 men, ages 35-67 years (mean, 48 years), who had been chosen based on their exposure to a wide variety of occupational and leisure-time physical activities. The computed T2-relaxation times and the T2-weighted and proton density-weighted signal intensities of the erector spinae, quadratus lumborum, and psoas major muscles had almost no association with any of the strength tests. The cross-sectional areas of the muscles had good correlations with isokinetic lifting strength (r = 0.46-0.53). They did not correlate well with psychophysical lifting and static back muscle endurance. Other characteristics or neurological or psychological factors may have more influence on those tests.
