Resultados da cirurgia de reservatórios ileais em pacientes com doença de Crohn

BACKGROUND: Total rectocolectomy and ileal pouch-anal anastomosis is the choice surgical procedure for patients with ulcerative colitis. In cases of Crohn's disease post-operative diagnosis, it can be followed by pouch failure. AIM: To evaluate ileal pouch-anal anastomosis long-term outcome in patients with Crohn's disease. METHODS: Between February 1983 and March 2007, 151 patients were submitted to ileal pouch-anal anastomosis by Campinas State University Colorectal Unit, Campinas, SP, Brazil, 76 had pre-operative ulcerative colitis diagnosis and 11 had post-operative Crohn's disease diagnosis. Crohn's disease diagnosis was made by histopathological biopsies in nine cases, being one in surgical specimen, two cases in rectal stump, small bowel in two cases, ileal pouch in three and in perianal abscess in one of them. The median age was 30.6 years and eight (72.7%) were female. RESULTS: All patients had previous ulcerative colitis diagnosis and in five cases emergency colectomy was done by toxic megacolon. The mean time until of Crohn's disease diagnosis was 30.6 (6-80) months after ileal pouch-anal anastomosis. Ileostomy closure was possible in 10 cases except in one that had ileal pouch fistula, perianal disease and small bowel involvement. In the long-term follow-up, three patients had perineal fistulas and one had also a pouch-vaginal fistula. All of them were submitted to a new ileostomy and one had the pouch excised. Another patient presented pouch-vaginal fistula which was successfully treated by mucosal flap. Three patients had small bowel involvement and three others, pouch involvement. All improved with medical treatment. Presently, the mean follow-up is 76.5 months and all patients are in clinical remission, and four have fecal diversion. The remaining patients have good functional results with 6-10 bowel movements/day. CONCLUSION: Crohn's disease diagnosis after ileal pouch-anal anastomosis for ulcerative colitis may be usual and later complications such fistulas and stenosis are common. However, when left in situ ileal pouch is associated with good function.

Edema pulmonar neurogênico: relato de dois casos

Neurogenic pulmonary edema is a rare and serious complication in patients with head injury. It also may develop after a variety of cerebral insults such as subarachnoid hemorrhage, brain tumors and after epileptic seizures. Thirty six patients with severe head injury and four patients with cerebrovascular insults treated in Intensive Care Unit of HC-UNICAMP from January to September 1995 were evaluated. In this period there were two patients with neurogenic pulmonary edema, one with head injury and other with intracerebral hemorrhage. Diagnosis was made by rapid onset of pulmonary edema, severe hypoxemia, decrease of pulmonary complacence and diffuse pulmonary infiltrations, without previous history of tracheal aspiration or any other risk factor for developement of adult respiratory distress syndrom. In the first case, with severe head trauma, neurogenic pulmonary edema was diagnosed at admission one hour after trauma, associated with severe systemic inflammatory reaction, and good outcome in three days. The second case, with hemorragic vascular insult, developed neurogenic pulmonary edema the fourth day after drenage of intracerebral hematom and died.

Desenvolvimento e avaliação de uma servoválvula de baixo custo para a aplicação de insumos líquidos

The present work aimed the development of a low cost servo-valve that answers to an electronic control signal, for variable rates liquid inputs application. A literature research to define which valve type should be used was made. A mechanically activated proportional valve with an electronically controlled servo-engine was designed and evaluated. Since developed the servo-valve, the system was submited to a number of tests .The evaluation of its behavior was obtained in terms of repeatability, hystheresis and linearity. The test was accomplished in a bench, specially developed for this aim. As a result, were obtained three curves of opening percentage as function of flow rate, describing three opening and closing increments in two different work pressures. The servo-valve presented a good repeatability, reasonable hysteresis and a typically quadratic curve. This one maintained the low cost target. These results were very satisfied because the non-linearity and the hysteresis could be easily corrected by software.

Adequação de engates rápidos de aspersores como conectores de mangueira para distribuição de água em sulcos de irrigação

As a way to reduce water losses in furrow irrigation systems, used in fresh market tomato production, farmers are improperly distributing water into the field using plastic hose. The objective of this work was to study the suitability of using quick coupler sprinkler as hose connectors for water distribution in tomato plantation. The first step of the study was to assess the current hose field operation for tomato growers. Subsequently, four models of quick couplers sprinklers available in the market were tested in laboratory to determine the coefficient of resistance, the equivalent tube length, the head loss curve and the linking efficiency. As result, a structural design for hose connectors was presented using the model of coupling with the best hydraulic performance. Additionally, some technical recommendations on its use in irrigation water distribution are highlighted. Despite the requirement for additional field trials, the proposed system has potential to optimize the water use efficiency, to improve workers ergonomic conditions, and ensure good profitability to the producer.

Is size structure a good measure of future trends of plant populations? an empirical approach using five woody species from the Cerrado (Brazilian savanna)

Size distributions in woody plant populations have been used to assess their regeneration status, assuming that size structures with reverse-J shapes represent stable populations. We present an empirical approach of this issue using five woody species from the Cerrado. Considering count data for all plants of these five species over a 12-year period, we analyzed size distribution by: a) plotting frequency distributions and their adjustment to the negative exponential curve and b) calculating the Gini coefficient. To look for a relationship between size structure and future trends, we considered the size structures from the first census year. We analyzed changes in number over time and performed a simple population viability analysis, which gives the mean population growth rate, its variance and the probability of extinction in a given time period. Frequency distributions and the Gini coefficient were not able to predict future trends in population numbers. We recommend that managers should not use measures of size structure as a basis for management decisions without applying more appropriate demographic studies.

Avaliação in vitro do aparelho DIAGNOdent para diagnóstico oclusal

The aim of this study was to determine the effectiveness and reliability of laser fluorescence measurements in relation to occlusal caries diagnosis. DIAGNOdent 2095 (Kavo, Biberach, Germany), which has been developed especially for caries diagnosis, was utilized. Five (5) teeth were examined in the pilot test; after that, ten (10) teeth were examined in order to calibrate both examiners. Data were obtained from 66 teeth (36 molars and 30 premolars), totalizing 144 sites identified through photographs of the occlusal surfaces. Reproducibility was evaluated in 10 teeth. The interexaminer Spearman correlation (r) was 0.89 and the intra-examiner, 0.93 and 0.97 (examiner A and B, respectively). Validation was carried out by histological examination (stereomicroscope). For the two examiners the sensitivity of the device was relatively high, varying from 0.81 to 1.00, while specificity varied according to which validation criterion was used (0.77 - 0.86: enamel lesion / 0.52 - 0.59: dentin lesion). It was concluded that DIAGNodent presented good capacity of identifying any alteration of the dental surface, nevertheless it presents the disadvantage of accomplishing many false-positive diagnosis when the validation criterion is dentin lesion.

Determinação do máximo déficit acumulado de oxigênio: efeito da duração dos testes submáximos para predição da demanda de oxigênio

The aim of this study was to investigate the influence of different assessment time periods of submaximal tests on the determination of the maximal accumulated oxygen deficit (MAOD), through the adoption of different time slots of 4 to 6, 6 to 8 and 8 to 10 min. Ten cyclists with mean age of 27.5 ± 4.1 years, body mass 74.4 ± 12.7 kg and time experience of 9.8 ± 4.7 years participated in this study. The athletes underwent an incremental exercise test to determine the peak oxygen consumption (VO2peak), and four submaximal constant work-load test sessions (60, 70, 80 and 90% VO2peak) of 10 min in order to estimate the O2 demand (DEO2). The mean VO2 values obtained on each constant work-load for the 4 to 6, 6 to 8 and 8 to 10 min time-periods intervals were used to perform a linear regression between the intensity and O2 consumption for each time-period. In addition, the subjects performed one supramaximal rectangular test (110% VO2peak) for the quantification of MAOD. There was no significant difference in VO2 between the different time-periods for all submaximal tests (P> 0.05). Similarly, no significant difference was found in DEAO2 and MAOD (P> 0.05). Furthermore, the values of MAOD for the three time-periods intervals showed good agreement and strong correlation. Thus, the data suggest that the submaximal tests used to estimate the values of MAOD can be reduced, at least in this type of sample, and with the use of a cycle simulator.

Efeito de 13 semanas de treinamento físico militar sobre a composição corporal e o desempenho físico dos alunos da escola preparatória de cadetes do exército

INTRODUCTION: Armies from all over the world acknowledge the importance of good physical fitness for the performance of military duties. The Military Exercise Training (MET) attempts to provide assistance to this search for better physical fitness and performance. OBJECTIVE: To verifying the effect on the body composition and physical performance of the students at ESPCEX (Military School for Preparation of Army Cadets) after 13 weeks of MET. METHODS: The sample was formed by 287 male students from the ESPCEX, whose average age was 18.33 ±1.26. Such students accomplished a boarding school routine, having defined schedules, meals and activities from which they were only released during the weekends. The MET was accomplished five days a week and it comprised both aerobic and resistance training. Measurement of body mass, height, skinfold (triceps, abdominal and suprailiac) was accomplished during pre and post training periods, and the following tests were performed: 12-minutes-run, oblique sit up, arm push up and pull up. Fat percentage, fat-free body mass and fat body mass were calculated using the anthropometric data based on the Guedes 3 skinfold protocol. RESULTS: Significant reduction in fat body mass, fat percentage and in triceptal and abdominal skinfold, as well as increase in suprailiac skinfold and fat-free body mass was observed when anthropometric and body composition data were compared, during the initial and the final periods of training. Significant improvement also occurred in all prformed physical tests, in which better performance was achieved. CONCLUSION: The acquired data suggest that performance of MET 5 days a week brought significantly improved body composition as well as physical performance

Féculas fermentadas na fabricação de biscoitos: estudo de fontes alternativas

The fermented cassava starch has been used as raw material for many products of the Brazilian culinary mainly in the biscuit manufacturing. Starch of arrowroot, english potato, baroa-potato and cassava were extracted and fermented in order to investigate other fermented starch sources for manufacturing biscuits. The fermented starch showed characteristics similar to those of commercial fermented cassava starch. The biscuits manufactured from the fermented starch of english potato didn?t expand and was very hard and the biscuits manufactured from the fermented starch of arrowroot and of baroa-potato were approved by the consumers and can be used in the biscuit manufacturing the same way as the fermented cassava starch.

Desidratação osmótica de abacaxi aplicada à tecnologia de métodos combinados

The aim of this research was to optimize osmotic dehydration of pineapple, according to two criteria: maximize water loss and minimize solid gain. The process was made as an application to Combined Methods Technology, in which three preservation factors were combined: water activity, pH and chemical preservatives, all being applied at low levels, in order to get a product resembling non-processed fruit. The experiment was divided into three treatments, being: non-coated pineapple pieces (A), pieces coated with alginate (B) and coated with low-methoxyl pectin (C). Process involved the following main steps: enzymatic inactivation of fruit pieces; in treatments B and C, incorporation of their respective coatings; and osmotic dehydration, in sucrose syrup containing potassium sorbate and citric acid. Optimum conditions, determined from Response Surface Methodology, were the following: dehydration of fruit pieces coated by alginate, at 42-47° C, in sucrose syrup at 66-69° Brix, for 220 to 270 minutes. Results indicated that both coatings significantly affected the mass transfers of the process, reducing solid incorporation and increasing water loss; therefore, increasing weight loss and performance ratio (water loss: solid incorporation) took place. Water activity was not significantly affected by the coatings. The product obtained under optimum conditions was submitted to sensorial evaluation, and presented a good general acceptance. Moulds and yeasts countings indicated good microbiological stability of the product for at least 60 days at 30ºC.

Atypical antipsychotics in the treatment of pathological aggression in children and adolescents: literature review and clinical recommendations

Objective: To review the literature about the use of atypical antipsychotics in the treatment of pathological aggression in children and adolescents. Method: The databases MEDLINE, SciELO, and LILACS were searched for publications in Portuguese or English from 1992 to August 2011 using the following keywords: mental disease, child, adolescent, treatment, atypical antipsychotic, aggressive behavior, aggression, and violent behavior. Results: Sixty-seven studies of good methodological quality and clinical interest and relevance were identified. Studies including children and adolescents were relatively limited, because few atypical antipsychotics have been approved by the Food and Drug Administration (FDA). All the medications included in this review (risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole and clozapine) have some effectiveness in treating aggression in children and adolescents, and choices should be based on clinical indications and side effects. Conclusions: There are few studies about the effectiveness and safety of atypical antipsychotics for the pediatric population, and further randomized controlled studies with larger groups of patients and more diagnostic categories, such as severe conduct disorder and oppositional defiant disorder, should be conducted to confirm the results reported up to date and to evaluate the impact of long-term use.

Politetrafluoroetileno e esclera humana no tratamento cirúrgico de perfuração escleral em coelhos

Purpose: An experimental study to evaluate the behavior of polytetrafluoroethylene (Gore-Tex®) compared with human sclera, in scleral perforations induced in rabbits eyes was performed. Methods: Twenty-two eyes of rabbits were submitted to scleral perforation followed by Gore-Tex® graft in the left eye and human sclera graft in the right eye respectively. During one month the postoperative evolution was analyzed every day: intensity of hyperemia, presence of infection, secretion, rejection and tonicity of the eyes. Results: No cases of secretion, infection or rejection were observed. The histological sections showed fibrosis in the eyes with Gore-Tex®, good adhesion and epithelization. Conclusion: The Gore-Tex® showed to be a plausible material to be used as graft in scleral defects with some advantages such as easy obtention, good handling and durability.

Comparação da eficácia da ropivacaína 1% quando associada ou não à hialuronidase na anestesia peribulbar para cirurgia de catarata

Purpose: To evaluate the onset time and quality of peribulbar anesthesia with 1% ropivacaine associated or not with hyaluronidase 100 tru/ml for cataract extraction. Methods: Prospective, randomized, double-blind and controlled study including fifty-seven patients, scheduled to undergo peribulbar anesthesia for cataract extraction, allocated to two groups. Group C: 1% ropivacaine with addition of 100 tru/ml hyaluronidase, and Group S 1% ropivacaine, without hyaluronidase. The onset time for globe akinesia was studied at intervals of 2 minutes, using Nicoll's score. We evaluated pain by analogic score during the surgery and the necessity of complementing the anaesthesia. The peribulbar block was considered satisfactory when the Nicoll's score was less than 4. Results: The mean time of onset of block in group C was 4.07 minutes (± 3.24), and in group S 5.03 (± 3.28). There was no statistically significant difference between the groups. Both were similar regarding pain score, no pain was observed in 57.14% of group C, and in 68.97% of group S. The supplementary anesthetic was necessary in 2 cases of group C and in 3 cases of group S. Two cases of bradycardia (heart rate < 50 bpm) were observed during the surgery, and in one case administration of atropine IV was necessary. Conclusion: 1% ropivacaine provided a good quality of anesthesia for cataract extraction, with a faster onset of action in the group with hyaluronidase 100 iu/ml, although without significant difference.
