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.

Abstract: the ingestion of caustic substances is an important emergency situation, because of its serious consequences. purpose: to study morphological and functional alterations of the esophagus in rabbits submitted to esophageal infusion of caustic soda (naoh). methods: the 88 rabbits studied were divided into 4 groups: g1 (n=22) were submitted to esophageal infusion with distilled water. g2, g3, and g4 were submitted to esophageal infusion of 2%, 4% and 6% naoh respectively. morphological alterations were studied in 12 animals from each group and manometric alterations in the remaining 10. an analysis was made of lower esophageal sphincter (les) pressure, number and amplitude of contractions in the distal third of the esophagus. these studies were performed before (moment m1) and at 30 minutes, 6 hours, and 24 hours after (moments m2, m3, and m4, respectively) esophageal infusion. results: morphological evaluation: g1 - no alterations; g2 - edema, hyperemia, and ecdysis; g3 - enlarged calibre of esophagus, ulcers, ecdysis of mucosa; g4 - lesions similar to g3, but more intense, areas of extensive hemorrhage at m3 and m4. functional evaluation: les was higher at m2; the number of distal third lower esophageal contractions in g3, and g4 was lower; and the contraction amplitude was lower in g4. conclusions: 1) esophageal infusion with caustic soda in rabbits is a good experimental model for studying caustic esophagites. 2) esophageal infusion with naoh caused lesions in the esophageal wall, with gravity proportional to solution concentration; 3) infusion caused les spasm at m2, and reduced both contraction number and amplitude in the distal third of the esophagus.

Abstract: purpose: to evaluate the biochemical behavior of compensatory lung growth after trilobectomy in undernourished rats. methods: undernutrition was achieved by offering 33% normal daily diet to 137 adult male wistar rats over an acclimatization period and throughout the experiment. rats were randomly distributed into nine (3 control, 3 thoracotomy, and 3 trilobectomy) groups. analysis was 7, 30, and 90 days after surgery (trilobectomy is middle, accessory and caudal lobectomies). body mass, lung mass, and lung tissue protein content were studied. results: cranial lobe and left lung mass both larger in trilobectomized rats throughout the study compared to the other groups. comparing combined lung mass, we noted that there was sufficient compensatory growth to be on a par with controls. cranial lobe and left lung protein content in trilobectomized rats both displayed the same behavior as lung mass throughout the study, but the compensatory growth in the remaining two lobes was not sufficient to make up for trilobectomy losses. conclusion: in adult undernourished rats, there was compensatory lung growth after trilobectomy, there was also lung mass recovery at the beginning of the study compared to other groups. throughout the study, cranial lobe and left lung protein content were higher in trilobectomized rats than other groups.
