Results of conventional and hysteroscopic surgery

Müllerian anomalies usually come to medical attention when they become problematic and require treatment. Most of these complications require surgical correction. The most commonly presenting anomaly is the double uterus which can be the source of recurrent abortion and preterm deliveries. The Strassman, Jones and Tompkins metroplasties have been shown to greatly improve the rate of successful deliveries in these patients. Hysteroscopic metroplasty, using either scissors, resectoscope or laser is now the recommended treatment for most septate uteri due to its relative simplicity, low morbidity and excellent reproductive outcome.     

Anatomical and surgical aspects of splenic segmentectomies

Cypermethrin is a synthetic pyrethroid that belongs to a group of insecticides with low mammalian toxicity but high insecticidal activity. The present study was designed to investigate the toxicity of cypermethrin on freshly isolated hepatocytes from male and female rats. Hepatocytes were harvested by a collagenase perfusion technique and were exposed to different concentrations of cypermethrin (100, 200, 400, or 800 ng/2 x 10(6) cells) for up to 2 h. Cell viability and the leakage of aspartate transaminase (AST) and alanine transaminase (ALT) were determined throughout the incubation period. The cell viability of the hepatocytes from male and female rats exposed to 400 ng and 800 ng was significantly reduced after 60 and 30 min of incubation, respectively. With cells from female rats, viability was also reduced upon exposure to 200 ng cypermethrin for 2 h. The decrease in cell viability was dose and time dependent. The leakage of ALT and AST was significantly increased with 400 and 800 ng concentrations at 60 and 30 min, respectively. ALT leakage from female hepatocytes was significantly increased at 60 min of incubation with the 200-ng dose, whereas 2 h of incubation was required for the leakage of ALT from the cells of male rats. The present data indicate that cypermethrin has toxic effects on male and female rat hepatocytes in a dose- and time-dependent manner. The data suggest that female rat hepatocytes may be more sensitive to the toxic effects of cypermethrin than male cells.     

Obesity

Obesity is a chronic disease, which similar to diabetes and hypertension, requires long-term treatment. The patient must be willing to make major changes in eating habits, lifestyle, and physical activity to achieve long-lasting results.     

Agreement between rectal and tympanic membrane temperatures in marathon runners

STUDY OBJECTIVE: To determine the agreement between rectal temperature and infrared tympanic membrane temperatures in marathon runners presenting to a field hospital at the finish line. METHODS: The subjects of this prospective, blinded, controlled study were runners 18 years or older who were triaged to the acute care medical area at the finish line for suspected hypothermia, hyperthermia, dehydration, or altered mental status. Rectal and tympanic temperatures were measured simultaneously in all subjects for whom rectal temperature measurement had been deemed necessary and recorded on separate data cards. RESULTS: Of the 239 runners treated in the acute care medical area, 37 required rectal temperature measurement and were enrolled in the study. The mean rectal temperature was 38.45 degrees +/- 1.20 degrees C (range, 35.9 degrees to 41.5 degrees C). The mean tympanic membrane temperature was 37.81 degrees +/- 95 degrees C (range, 36.3 degrees to 40.4 degrees C). Pearson's correlation coefficient revealed a moderate correlation (r = .6902, P = .00023). The mean temperature difference between the two thermometers, mean rectal minus mean tympanic membrane, was .64 degrees C (95% confidence interval, .35 degrees to .93 degrees C). Sixty-Two percent of the tympanic membrane readings were within 1 degree C of their rectal counterparts. Agreement ranged from 1.16 degrees (+2 SD) to -2.95 degrees (-2 SD). The 95% confidence interval was 1.67 degrees to -2.95 degrees C. CONCLUSION: We were able to demonstrate only a moderate correlation between the two thermometer readings, with a wide spread between the limits of agreement. This spread could be clinically significant and therefore limits the usefulness of tympanic temperature in the marathon race setting. Because of the potentially large and clinically significant differences in rectal and tympanic temperatures and the limitations inherent in our study, we cannot endorse the use of tympanic temperature in the setting of a marathon event.     

Immunogenic properties of an anti-DNA antibody-derived peptide, 88H.64-80: location of a dominant idiotope defined by T and B cells

Plasma interleukin-1 beta (Il-1 beta) interleukin-6 (Il-6) and tumor necrosis factor-alpha (TNF-alpha) concentrations were measured in 26 women with Anorexia Nervosa (AN), nine of the restricted type (AN-R) and 17 of the binge-eating/purging type (AN-BP), in 24 women with Bulimia Nervosa (BN) and in 26 healthy age- and sex-matched controls. Concentrations of the cytokines were measured at the beginning of the study before starting any treatment and then after 1 and 3 months of combined cognitive-behavioral and pharmacological therapy (fluoxetine for AN-R and AN-BP, amineptine for AN-BP and BN, and fluvoxamine for BN). Basal values of Il-1 beta, Il-6 and TNF-alpha, were the same in patients and controls and did not change during treatments, in spite of the improvement of the mental disorders. This seems to exclude the possibility that alterations of basal plasma cytokine secretion are involved in the etiopathogenesis of AN and BN.     

Family planning knowledge, attitudes and practices in women with schizophrenic spectrum disorders

This study set out to test three hypotheses about family planning in women with schizophrenic spectrum disorders, as compared to demographically comparable non-mentally ill control women: that they (1) report at least as much unprotected intercourse while not desiring pregnancy; (2) have less knowledge about contraception; and (3) perceive more, and different, obstacles to obtaining or using birth control. A semistructured Family Planning Interview was administered to subjects (n = 44) with Research Diagnostic Criteria diagnoses of schizophrenia and schizoaffective disorder, and to non-mentally ill control subjects (n = 50). The participants had high rates of unprotected intercourse, as did non-mentally ill controls. They had significantly less reproductive and contraceptive knowledge than the control subjects, and were more likely to perceive birth control as difficult to obtain. The most common reason women with schizophrenic spectrum disorders gave for failing to use birth control was that they did not expect to have sex, while that given by non-mentally ill subjects related to side-effects of birth control. Important obstacles to family planning in women with schizophrenic spectrum disorders include relative lack of knowledge and difficulty planning ahead. Although many women with schizophrenia could benefit from long-acting, reversible contraception, many may be unaware of those options and/or may find them difficult to obtain. Integrating family planning with mental health care might better address the unique needs of this population.
