The Distribuition of Strongyloides stercoralis Frequency in Araraquara, São Paulo State - Brazil

Strongyloidiasis is a disease of emerging public health importance. A survey was conducted in Araraquara city, São Paulo state, Brazil, in order to evaluate the frequency distribution of Strongyloides stercoralis in the area. A total of 9582 single stool samples were examined by direct examination, and by the Coprotest and Rugai's methods from January 2005 to January 2007. Out of the total samples examined, 408 (4,3%) were found to be infected by S. stercoralis (143 men and 265 women). The months with the highest frequency (5,0 - 8,2%) of positive patients were February, September and December (2005); April and November (2006) and January (2007). The frequencies from the other months varied around 2,5 to 4,9%. It was concluded that strongyloidiasis is endemic in Araraquara, but in some months, which presented the highest temperatures followed by rainy periods, the frequencies are typical from hyperendemic areas.

Spliceosomal factors are recognized by Chagasic sera

We investigated the possibility that Chagas' patients develop an autoimmune response to human UsnRNPs or Sm epitopes. Using purified human UsnRNPs we detected anti-human UsnRNPs antibodies in sera from patients with Chagas' disease. The antibodies were also detected using peptide-ELISA containing the Sm-motif 1 domain, showing that 61% (31/51) of the Chagas sera contained antibodies against the Sm-motif 1. Our preliminary results obtained by immunoprecipitation using Chagas chronically infected Balb/C sera and HeLa nuclear extracts showed that some autoantibodies could also be found during the course of the disease. Groups of 20 mice tone-month-old) were infected i.p. with Y strain 30 bloodstream trypomastigotes and killed at 60 days post-infection and sera were used for immunoprecipitation analysis as mentioned, These antibodies cross-reacted with U2 snRNP in HeLa nuclear extract and revealed many different bands in T. cruzi nuclear extract. These results suggest that the autoantibodies may have a role in the pathogenesis of the disease,

Cheap assays of malate, glycerol and ethanol in fermenting must and food samples

A preparation, enriched with malate dehydrogenase (MDH), alcohol dehydrogenase (ADH), glycerol -3- P dehydrogenase (GPDH) and glycerol kinase (GK), was obtained from dry baker's yeast. This preparation was used to assay glycerol, ethanol and malate measuring the variations in absorbance (NADH formation) at 340 nm. Good degrees of recoveries were obtained when glycerol was added to red wine and fermenting sugar-cane juice and when L-malate was added to commercial apple juice samples. Good results were also obtained when ethanol was assayed in fermented sugar-cane juice and wine samples, using both the partially purified preparation obtained from dry yeast and a purified commercial alcohol dehydrogenase.

Blepharo-cheilo-dontic (BCD) syndrome: Report on four new patients

We report on four Brazilian patients with, among other signs, cleft lip and palate, dental anomalies, ectropion of the lower eyelids, euryblepharon, and lagophthalmia, Two were sporadic cases and two were familial cases, a mother and her equally affected son, Recently, the reports with different combination of these signs were reviewed by Gorlin et al, [1996; Am J Med Genet 65:109-112] and named blepharo-cheilo-dontic (BCD) syndrome, Variable expressivity and autosomal dominant inheritance were observed.

Effect of the Oxygen on the Mechanical Properties of Ti-Mo Systems Alloys

Titanium alloys normally contain oxygen, nitrogen, or carbon as impurities, and although this concentration is low, these impurities cause changes in the mechanical properties of Ti alloys. Oxygen is a strong alpha-phase stabilizer and its addition causes solid-solution strengthening, shape memory effect, and superelasticity. The most promising alloys are those with Nb, Zr, Ta, and Mo as alloying elements. In this paper, the preparation, processing, and characterization of Ti-Mo alloys (5 and 10 wt%) used as biomaterials are presented, along with the influence of oxygen on their mechanical properties. The addition of oxygen causes an increase in the elasticity modulus of the Ti-5Mo alloy due to an increase in the alpha' phase volume fraction, which possesses a higher modulus than the alpha '' phase. Ti-10Mo possesses a mixture between alpha '' and beta phases, oxygen enters these two structures and causes a dominating effect.

Preoperative and Postoperative Nutritional Evaluation in Patients with Non-advanced Megaesophagus

Megaesophagus, an affection characterized by aperistalses of the esophageal body and deficient relaxation of lower esophageal sphincter, has disphagia as main symptom. The aim of this study was to evaluate the nutritional status of patients with non advanced megaesophagus in pre and post-operative periods of cardiomyotomy. Ten patients were evaluated at 5 moments (pre-operative - M 1 and post-operative - 1, 3, 6 ant 12 months after surgery). The anthropometric, hematimetric and biochemical parameters were studied in the 5 moments. Conclusions: 1. Most 017 the patients with non-advanced megaesophagus are eutrophic; 2. Surgical treatment determines an improvement in nutritional status and an increase in HDL cholesterol values.

Submucous fibroids classification - STEP-W classification

Objective: To develop a new submucous fibroids classification for evaluating the viability and the degree of difficulty and complexity of a hysteroscopic myomectomy.Methods: We have included more four parameters in addition to penetration the fibroid into the myometrium. The extra-parameters were: size of the fibroid, it topography, it extension of the base in relation the wall was set and the wall it was set. The fibroids were classified according to the Classification of the European Society for Gynaecological Endoscopy (ESGE) and to the new classification (STEP-W) in patients who were submitted to hysteroscopic resection of submucous fibroids. The possibility of total resection of the fibroid, the operating time, the fluid deficit and the frequency of any complications were considered. The Fisher test, the Student t test and the analysis of variance test were used in the statistical analyses. It was considered statistically significant when the p-value was less than 0.05 in the two-tailed test.Results: In group which the hysteroscopic surgery was considered complete there was no significant difference between the three ESGE levels (0, 1 and 2). Using the STEP-W, the difference between the numbers of complete surgeries was significant (p < 0.001) for the two levels (groups I and II). The difference between the operating times was significant for the two classifications. In relation to the fluid deficit, only the STEP-W showed significant differences between the levels (p=0.02).Conclusions: It seems to us that the new classification (STEP-W) gives more clues to the difficulties of a hysteroscopic myornectomy than the standard classification (ESGE).

Effect of melatonin on the oxidative metabolism of colostrum phagocytes of diabetic women

Aim: the aim of this study was verified the ability of melatonin hormone to modulate the oxidative metabolism of colostral phagocytes from diabetic mothers. Methods: based on 100g-OGTT and glucose profile analysis subjects were allocated into two groups: Non-diabetic (ND-10) and Diabetic (DM-8). Cells were separated by a Ficoll-Paque gradient and the oxidative metabolism was available thought superoxide release by colostrum phagocytes using the cytochrome C method. Results: melatonin hormone increased superoxide release by colostrum phagocytes of ND and decreased these release in colostrum phagocytes of DM mothers. Conclusion: the results suggest that the melatonin hormone can modulate the oxidative metabolism of phagocytes and an existence of relationship between control of glucose metabolism and melatonin action in colostrum phagocytes.

Internal carotid artery pseudoaneurysm after tonsillectomy treated by endovascular approach - A case report

Surgery on the head and neck region may be complicated by vascular trauma, caused by direct injury on the vascular wall. Lesions of the arteries are more dangerous than the venous one. The traumatic lesion may cause laceration of the artery wall, spasm, dissection, arteriovenous fistula, occlusion or pseudoaneurysm.We present a case of a child with a giant ICA pseudoaneurysm after tonsillectomy, manifested by pulsing mass and respiratory distress, which was treated by endovascular approach, occluding the lesion and the proximal artery with Histoacryl. We reinforce that the endovascular approach is the better way to treat most of the traumatic vascular lesions.

Esophageal and gastric biopsies in symptomatic children and adolescents. Should both be performed?

This study investigated the relationship among the histological diagnosis of esophagitis and gastritis in children and adolescents with gastroesophageal reflux disease (GERD) and/or dyspepsia. Records of 366 patients submitted to endoscopic biopsies were reviewed. Two groups were analyzed: G1 n=258 with esophageal and gastric biopsies, G2 n=108 with gastric biopsies only. For total subjects median age (range) was 8.5y (2mo-19.9y). Helicobacter pylori infection was detected in 30.6 %, median age 12.5y for H pylori-infected and 5.5y for uninfected children. Histological esophagitis was found in 216/258 (83.7 %) and gastritis in 95/258 (36.8 %) of G1. Both biopsies were normal for 13.6 % cases. Normal gastric biopsies were associated with esophagitis in 128/ 163 (78.5 %) of G1, but gastritis was associated with normal esophageal biopsies in only 7/95 (7.4 %) (0<.001). Histological gastritis was found in 80/108 (74.1 %) of G2 patients. Therefore, for symptomatic children both biopsies are indicated.
