Abstract: purpose: to evaluate the effect of total abdominal hysterectomy on ovarian blood supply in women in reproductive age, using transvaginal color doppler. methods: a prospective study was carried out on 61 40-year-old or younger women. they were divided into two groups: g1, 31 patients submitted to hysterectomy, and g2, 30 normal women. criteria of inclusion: normal ovarian function at baseline, normal body weight, without expasure to tobacco, no history of laparotomy or ovarian pathology. the pulsatility index (pi) of ovarian arteries determined by doppler and the transvaginal ultrasonographic measurement of the ovarian volume were performed at three moments: baseline, 6 and 12 months. results: at baseline the groups were homogeneous. in the hysterectomized group, with 6 and 12 months, increase of the volume of the ovaries and decrease of pi (p<0,05) were observed. at the end of the study, 25.5% (8/31) of the hysterectomized patients presented benign ovarian cysts. in the control group no alteration of the parameters was observed. conclusion: the decrease of pi by doppler of ovarian arteries suggests increased ovarian blood supply after total abdominal hysterectomy in women in reproductive age.

Abstract: purpose: to evaluate the importance of the oral glucose tolerance test for the diagnosis of glucose intolerance (gi) and type 2 diabetes mellitus (dm-2) in women with pcos. methods: a retrospective study was conducted on 247 patients with pcos selected at random. the diagnosis of gi was obtained from the two-hour oral glucose tolerance test with 75 g of glucose according to the criteria of the world health organization (who) (gi: 120 minutes for plasma glucose >140 mg/dl and <200 mg/dl), and the diagnosis of dm-2 was obtained by both the oral glucose tolerance test (dm: 120 minutes for plasma glucose >200 mg/dl) and fasting glucose using the criteria of the american diabetes association (impaired fasting glucose: fasting plasma glucose >100 and <126 mg/dl; dm: fasting glucose >126 mg/dl). a logistic regression model for repeated measures was applied to compare the oral glucose tolerance test with fasting plasma glucose. anova followed by the tukey test was used for the analysis of the clinical and biochemical characteristics of patients with and without gi and/or dm-2. a p<0.05 was considered statistically significant. results: pcos patients had a mean age of 24.8±6.3, and body mass index (bmi) of 18.3 to 54.9 kg/m2 (32.5±7.6). the percentage of obese patients was 64%, the percentage of overweight patients was 18.6% and 17.4% had healthy weight. the oral glucose tolerance test identified 14 cases of dm-2 (5.7%), while fasting glucose detected only three cases (1.2%), and the frequency of these disorders was higher with increasing age and bmi. conclusions: the results of this study demonstrate the superiority of the oral glucose tolerance test in relation to fasting glucose in diagnosing dm-2 in young women with pcos and should be performed in these patients.

Abstract:

Background: Laparoscopic cholecystectomy (LC) reduces surgical trauma and hospital stay, but requires effective and safe postoperative analgesia. This prospective and double-blind study investigated the effects of analgesia with tramadol combined with either dipyrone or ketorolac on the postoperative renal function of patients submitted to LC. Methods: Pre-and post-operatively (PO), estimated glomerular filtration rates (GFR), obtained by two formulas dependent on blood Cr and one on blood cystatin C values, and tubular enzymuria—alkaline phosphatase (AP), γ-glutamiltransferase (γ-GT)— were determined in well hydrated patients who underwent LC and analgesia with tramadol combined with either dipyrone (Dipyrone, n = 63) or ketorolac (Ketorolac, n = 63). Upon discharge from the post-anesthetic care unit (PACU), pain (through Verbal Numerical Scale—VNS) and need for rescue analgesia with morphine were evaluated. Results: There was hemodilution PO, which made GFR profile analysis more difficult—those dependent on Cr increased and statistically correlated, but those dependent on cystatin C did not change. There was a significant PO increase in AP in the Dipyrone and Ketorolac groups, and in the product of the both enzymes in the Ketorolac group. Upon PACU discharge, the Dipyrone group showed signifi

cantly higher VNS scores than the Ketorolac group. All patients received morphine PO, and the total dose needed for pain control differed between groups, but without statistical significance. Conclusions: The association of tramadol with dipyrone or ketorolac in well hydrated patients submitted to LC had similar analgesic effectiveness in the PACU. Postoperatively, the effect on GFR may have been masked by hemodilution, and enzymuria was discreetly enhanced when ketorolac was used.

Occurrence of enteroparasites in day care centers in Botucatu (S?o Paulo State, Brazil) with emphasis on Cryptosporidium sp., Giardia duodenalis and Enterobius vermicularis

Revista do Instituto de Medicina Tropical de S?o Paulo , 2006, DOI: 10.1590/S0036-46652006000500006
Abstract: the occurrence of the enteroparasites was verified in 279 children (0 to 6 years) of four municipal day cares of botucatu/sp. three samples of each child's feces were collected and processed by the methods of hoffman-pons-janner, faust and ritchie and subsequent coloration of the fecal smear by the methods of auramina-o and ziehl-neelsen modified for diagnosis of cryptosporidium sp. and graham method for diagnosis of enterobius vermicularis. of the analyzed children we verified a prevalence of intestinal parasitism in 53.40%, and the most frequent parasite was giardia duodenalis (26.88%). significant association was verified among enteroparasitosis, family income, maternal education and age; the lowest enteroparasite frequency occurred in children of families with larger income and higher education. it was observed that g. duodenalis is more prevalent in children from 0 to 4 years and e. vermicularis is more frequent in children between three and four years old. the high enteroparasite prevalence in day cares suggests complex structure in its epidemiology, where factors beyond sanitation should be considered.

Abstract: a knowledge of the imbibition stages shown by different species, is essential in research projects aiming at improvement of seed quality by treatments such as osmotic conditioning, initial wetting, and the use of bioregulators. the objective of this study was to establish a methodology to determine the limit between the first and second stages of the process, considering the model w = f(t) - (a - w0)exp(-kt), using statistical tests. this limit was determined using an asymptotic distribution of an estimator function. the data point beyond which the difference (w*) is no longer significant was determined using student's t statistics. the model is = (0.434 + 0.00162 t) - (0.434 - wo)exp(-0.121 t), with r2 = 0.98 and w* = (0.434 - wo)exp(-0.121 t) fits the utilized data. the calculated t value (27.2 hours) is smaller than the value that was determined considering a 1% value difference between the asymptote and the estimated model as a criterion for the stage change. this two-hour difference corresponds to 0.28% in absorbed water.

Abstract: in biologic experiments, in which growth curves are adjusted to sample data, treatments applied to the experimental material can affect the parameter estimates. in these cases the interest is to compare the growth functions, in order to distinguish treatments. three methods that verify the equality of parameters in nonlinear regression models were compared: (i) developed by carvalho in 1996, performing anova on estimates of parameters of individual fits; (ii) suggested by regazzi in 2003, using the likelihood ratio method; and (iii) constructing a pooled variance from individual variances. the parametric tests, f and tukey, were employed when the parameter estimators were near to present the properties of linear model estimators, that is, unbiasedness, normal distribution and minimum variance. the first and second methods presented similar results, but the third method is simpler in calculations and uses all information contained in the original data.

Abstract: growth functions with upper horizontal asymptote do not have a maximum point, but we frequently question from which point growth can be considered practically constant, that is, from which point the curve is sufficiently close to its asymptote, so that the difference can be considered non-significant. several methods have been employed for this purpose, such as one that verifies the significance of the difference between the curve and its asymptote using a t-test, and that of portz et al. (2000), who used segmented regression. in the present work, we used logistic growth function, which has horizontal asymptote and one inflection point, and applied a new method consisting in the mathematical determination of a point in the curve from which the growth acceleration asymptotically tends to zero. this method showed the advantage to have biological meaning besides leading to a point quite close to those obtained using the beforementioned methods.
