ABSTRACT

Part 1 of this guideline addressed the differential diagnosis of the neurofibromatoses (NF): neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2) and schwannomatosis (SCH). NF shares some features such as the genetic origin of the neural tumors and cutaneous manifestations, and affects nearly 80 thousand Brazilians. Increasing scientific knowledge on NF has allowed better clinical management and reduced rate of complications and morbidity, resulting in higher quality of life for NF patients. Most medical doctors are able to perform NF diagnosis, but the wide range of clinical manifestations and the inability to predict the onset or severity of new features, consequences, or complications make NF management a real clinical challenge, requiring the support of different specialists for proper treatment and genetic counseling, especially in NF2 and SCH. The present text suggests guidelines for the clinical management of NF, with emphasis on NF1.


A primeira parte desta diretriz abordou o diagnóstico diferencial das neurofibromatoses (NF): neurofibromatose do tipo 1 (NF1), neurofibromatose do tipo 2 (NF2) e schwannomatose (SCH). As NF compartilham algumas características, como a origem neural dos tumores e sinais cutâneos, e afetam cerca de 80 mil brasileiros. O aumento do conhecimento científico sobre as NF tem permitido melhor manejo clínico e redução da morbidade das complicações, resultando em melhor qualidade de vida para os pacientes com NF. A maioria dos médicos é capaz de realizar o diagnóstico das NF, mas a variedade de manifestações clínicas e a dificuldade de se prever o surgimento e a gravidade de complicações, torna o manejo da NF um desafio para o clínico e envolve diferentes especialistas para o tratamento adequado e aconselhamento genético, especialmente a NF2 e a SCH. O presente texto sugere algumas orientações para o acompanhamento dos portadores de NF, com ênfase na NF1.

ABSTRACT

Objective: To review of concepts and actions that aim to analyze the effects of internationalization of science and education, with emphasis in the medical field and its basement in development policies adopted by nations, exploring the potential for international interdisciplinary cooperation of each laboratory, department, university or institute. Method: Search of indicators to assess the degree of internationalization of universities and research institutes in several interconnected levels: organizational, regional, sectoral and global, and policy-making in science, technology innovation and higher education. Result: Scientific research is still carried out individually, but is now much more closely integrated with other social processes. The scientist is no longer a stranger who is allowed to surrender to his hobby to do what it wants. Internationalization of research and medical education, although it is among the topics of greatest need, as the globalized world, is difficult activity to be assessed. The leaders seem to have understood that the knowledge societies, leading to economic policy based on knowledge, can result in economic and social progress of nations. This fact has motivated increasingly the incentive to actions aimed at addressing global problems (eg health, climate change) by funding research that generates new knowledge. Conclusion: The consensus is that the internationalization of science is desirable and necessary for the sustainable development of nations. However it cannot be done only by encouraging and promoting the outward students and researchers abroad. It is necessary, in addition, offer conditions to foreign researchers and students teachers to work in collaboration with Brazilian and raise the country to international scientific standards.


Objetivo: Apresentar revisão dos conceitos e ações que objetivam analisar os efeitos da internacionalização da ciência e da educação, com ênfase na área médica e seu embasamento nas políticas de desenvolvimento adotadas pelas nações, explorando o potencial para cooperação internacional interdisciplinar de cada laboratório, departamento, universidade ou instituto. Método: Procura de indicadores que possam avaliar o grau de internacionalização das universidades e institutos de pesquisa em vários níveis interconectados: organizacional, regional, setorial e global e para definição de políticas nas áreas de ciência, tecnologia inovação e educação superior. Resultado: A pesquisa científica ainda é realizada individualmente, mas está atualmente muito mais intimamente integrada a outros processos sociais. O cientista não é mais um estranho que tem permissão para entregar-se ao seu passatempo de fazer aquilo que bem entende. Internacionalização da pesquisa e da educação médica, embora esteja entre os tópicos de maior reconhecimento como sendo necessidade do mundo globalizado, é atividade difícil de ser avaliada. Os governantes parecem ter entendido que as sociedades do conhecimento, induzindo a política econômica baseada no conhecimento pode resultar em progresso econômico e social das nações. Esse fato tem motivado de forma crescente o incentivo às ações que visam a abordagem de problemas globais (e.g. saúde, mudanças climáticas) pelo financiamento da pesquisa que gera conhecimento novo. Conclusão: É consenso que a internacionalização da ciência é desejável e necessária para o desenvolvimento sustentável das nações. Entretanto ela não pode ser feita somente incentivando e fomentando a ida de estudantes e pesquisadores para o exterior. É preciso, em adição, oferecer condições a professores pesquisadores e estudantes estrangeiros para que possam atuar em colaboração com os brasileiros e elevar o país aos padrões científicos internacionais.

ABSTRACT

PURPOSE: To describe a method to characterize the gelatinase activity of cultured human periodontal fibroblasts stimulated with Pam3Cys and E. coli LPS, ligands of TLR2 and TLR4 respectively, and by centrifugation of the cultures, simulating an orthodontic force. METHODS: To study MMP-2 activity, primary cultures of human periodontal fibroblasts were stimulated with the addition of TLRs 2 and 4 ligands and the application of mechanical force by centrifugation at 141 x g for 30 min. Supernatant media was collected 24 hours later to perform protein quantification and zymography. RESULTS: MMP-2 activity suffered an increase in cultures co-stimulated with TLRs 2 and 4 ligands alone or with the presence of mechanical force application compared to basal levels. CONCLUSION: Zymography, one of the several methods to study MMPs activities, is a simple, qualitative and efficient method based on electrophoresis of bis-acrylamide gels copolymerized with a protein substrate.

ABSTRACT

OBJETIVO: Descrever a, morbidade e a mortalidade em pacientes submetidos à hepatectomia. MÉTODOS: Avaliou-se o tipo de hepatectomia, necessidade de transfusão sanguínea peroperatória, permanência hospitalar, complicações e a mortalidade pós-operatórias. Para análise estatística utilizou-se o teste exato de Ficher, considerando-se significativos valores de p < 0,05. RESULTADOS: Foram realizadas 22 (31,43 por cento) hepatectomias maiores, 13 (18,57 por cento) hepatectomias direitas com uma alargada aos segmentos IVa e IVb; nove (12,86 por cento) hepatectomias esquerdas, dentre estas, seis incluíram o segmento I. Foram feitas 48 (68,57 por cento) hepatectomias menores, sendo 36 (51,43 por cento) ressecções segmentares e 12 (17,14 por cento) ressecções não anatômicas. A principal indicação para ressecção de metástases foi o adenocarcinoma colorretal em 27 (38,57 por cento) pacientes. O tumor primário de maior incidência foi o carcinoma hepatocelular em 14 (20 por cento) pacientes, seguido pelo colangiocarcinoma em seis (8,57 por cento) pacientes. Entre as 13 (18,57 por cento) ressecções para doenças benignas predominou a litíase intra-hepática (n=6). Seis pacientes (8,57 por cento) foram hemotransfundidos no peroperatório. A permanência hospitalar variou de 2 a 28 dias (média = quatro dias). Oito (11,43 por cento) pacientes desenvolveram complicações pós-operatórias. A mortalidade geral foi 8,57 por cento, concentrando-se nos pacientes com carcinoma hepatocelular (5,71 por cento). CONCLUSÃO: As metástases de adenocarcinoma colorretal foram as principais indicações cirúrgicas e as hepatectomias menores foram os procedimentos mais realizados. Apesar da baixa incidência geral de complicações pós-operatórias, evidenciou-se alta morbimortalidade em pacientes cirróticos com carcinoma hepatocelular.


OBJECTIVE: To describe morbidity and mortality in patients undergoing hepatectomy. METHODS: We evaluated hepatectomy according to type of surgery, perioperative blood transfusion, hospital stay, complications and postoperative mortality. For statistical analysis we used the Ficher's exact test, considering significant p values <0.05. RESULTS: We performed 22 (31.43 percent) major hepatectomies, 13 (18.57 percent) being right hepatectomies extended to segments IVa and IVb, nine (12.86 percent) left hepatectomies, among these, six included the segment I. We conducted 48 (68.57 percent) minor hepatectomies, 36 (51.43 percent) segmental resections and 12 (17.14 percent) non-anatomical resections. The main indication for resection was colorectal adenocarcinoma metastasis in 27 (38.57 percent) patients. The higher incidence of primary tumor was hepatocellular carcinoma in 14 (20 percent) patients, followed by cholangiocarcinoma in six (8.57 percent). Among the 13 (18.57 percent) resections for benign diseases, the predominant one was intrahepatic lithiasis (n = 6). Six patients (8.57 percent) received perioperative blood transfusion. Hospital stay ranged from 2 to 28 days (mean four days). Eight (11.43 percent) patients developed postoperative complications. Overall mortality was 8.57 percent, mostly in patients with hepatocellular carcinoma (5.71 percent). CONCLUSION: Metastatic colorectal adenocarcinoma was the main indication for surgery and minor hepatectomies were the most common procedures. Despite the low overall incidence of postoperative complications, there was high morbidity and mortality in cirrhotic patients with hepatocellular carcinoma.

ABSTRACT

BACKGROUND: Diagnosis of subtypes of chronic constipation has been considered difficult to achieve even in specialized centers. Although colorectal physiologic tests have brought an important contribution, it remains unclear in which patients these tests should be indicated for. AIMS: This study aims to establish a differential diagnosis for chronic constipation cases using clinical assessment and physiologic tests and to identify clinical parameters that could predict which patients need physiologic tests. METHODS: One hundred and seventy nine patients (83 percent females; mean age, 45) with chronic constipation according to Rome II criteria were initially treated by dietary advice and functional reeducation and those unresponsive (110 or 61.5 percent) were submitted to colonic transit time, defecography, anorectal manometry and electromyography, as needed. RESULTS: A differential diagnosis was achieved in 63.6 percent of patients tested. However, 61.5 percent of 179 patients with chronic constipation (69 with no need to tests and 40 with normal tests) have etiologic diagnosis established only on clinical basis. Irritable bowel syndrome (32 percent), pelvic floor dysfunction (29 percent) and functional constipation due to faulty diet and life style habits (22 percent) were the main causes of chronic constipation. Alternating constipation and nausea/vomiting were symptoms significantly related to the diagnosis of irritable bowel syndrome; younger age, larger intervals between bowel movements, occurrence of fecal impaction and necessity of enema were related to the diagnosis of non-chagasic megacolon and digital assistance to evacuate and large rectocele or spastic pelvic floor on rectal exam were associated to pelvic floor dysfunction. Patients with long-standing constipation, fecal impaction, abdominal pain not eased after defecation, necessity for enemas, digital assistance and evidence of rectocele tended to be in need for physiologic...


RACIONAL: O diagnóstico dos subtipos de constipação crônica tem sido considerado difícil de ser estabelecido, mesmo em centros especializados. Embora os testes fisiológicos tenham trazido uma importante contribuição, ainda há dúvidas quanto as suas indicações. OBJETIVOS: Estabelecer o diagnóstico diferencial em casos de constipação crônica através da avaliação clínica e da utilização de testes fisiológicos, procurando-se identificar parâmetros clínicos que poderiam predizer quais pacientes necessitariam de tais testes. MÉTODOS: Cento e setenta e nove pacientes (83 por cento do sexo feminino; média de idade de 45 anos) com constipação crônica de acordo com os critérios de Roma II foram inicialmente tratados com medidas dietéticas e reeducação funcional e aqueles que não responderam (110 ou 61,5 por cento) foram submetidos a tempo de trânsito colônico, defecografia, manometria anorretal e eletromiografia, de acordo com apresentação clínica da constipação crônica. RESULTADOS: O diagnóstico etiológico foi obtido em 63.6 por cento dos pacientes testados. Entretanto, em 61,5 por cento (69 que não necessitaram dos testes e 40 que tiveram testes normais), o diagnóstico etiológico foi estabelecido em bases clínicas. A síndrome do intestino irritável (32 por cento), a disfunção do assoalho pélvico (29 por cento) e a constipação funcional secundária a inadequação dietética e de hábitos de vida (22 por cento) foram os principais diagnósticos etiológicos da constipação crônica. A alternância de constipação e a presença de náuseas/vômitos estiveram significativamente relacionadas ao diagnóstico de síndrome do intestino irritável; idade precoce, grandes intervalos entre as evacuações, ocorrência de impactação fecal e necessidade de enemas estiveram relacionadas ao diagnóstico de megacólon não-chagásico, enquanto assistência digital para evacuar e grande retocele ou assoalho pélvico espástico ao toque retal se associaram à disfunção do assoalho pélvico...

ABSTRACT

OBJETIVO: Descrever técnica de curativo para cobertura temporária da cavidade abdominal que utiliza sistema de vácuo. MÉTODO: A técnica foi aplicada em 12 pacientes. Inicialmente coloca-se sobre a laparostomia a bolsa plástica fenestrada, em seguida a primeira camada de compressas. Sobre esta, coloca-se o tubo de látex. Este é recoberto por outra camada de compressas as quais são fixadas sobre o curativo com o campo cirúrgico auto-aderente. O tubo de látex é conectado ao sistema de vácuo com pressão de -10 a -50 mmHg. Trocam-se os curativos a cada 12 horas. Material utilizado bolsa plástica de solução salina, compressas cirúrgicas, tubo de látex, campo cirúrgico auto-aderente de 50cm x 30cm e vácuo do sistema de gases hospitalares. RESULTADOS:A peritonite grave foi a indicação mais freqüente para laparostomia, seguida da síndrome de compartimento abdominal. Fechamento definitivo da cavidade abdominal foi possível em oito pacientes (67 por cento) em média após 11 dias (9 a 21 dias) da laparostomia. Não houve complicações associadas ao método. O custo diário aproximado do curativo foi de R$ 50,00. CONCLUSÃO: O curativo a vácuo proporcionou boa contenção das vísceras abdominais, controlou o extravasamento de secreções e o edema. Permitiu o fechamento definitivo da cavidade abdominal na maioria dos casos e foi de baixo custo.


BACKGROUND: We describe a vacuum pack technique for a temporary abdominal wound closure. METHODS: The vacuum pack materials were a plastic sheet, laparotomy pads, latex tube, 50cm x 30cm adhesive-backed plastic, and a vacuum source. Twelve patients underwent the procedure as follows: we cut several slits in the plastic sheet, which is applied directly over the abdominal contents. We put laparotomy pads over the plastic sheet, and then a latex tube is placed over the laparotomy pads. Another layer of laparotomy pads is placed over the latex tube, which is stuck by an adhesive-backed plastic. We connect the tube to a vacuum source with negative pressure between -10 to -50 mmHg. The pack is changed every 12 hours. RESULTS: Severe peritonitis was the most common indication followed by the abdominal compartment syndrome. Definitive abdominal closure was performed in eight patients (67 percent) after an average of 11 days (9 to 21 days) from the first day of laparostomy. There were no complications directly associated with the method. Daily cost was approximately R$ 50.00. CONCLUSION: The vacuum pack kept the underlying abdominal viscera secure beneath the dressing; in addition, it controlled fluid leakage and edema. Definitive abdominal wound closure was possible in the majority of the patients. This was achieved at a reasonable financial cost.

ABSTRACT

PURPOSE: Scorpion toxin purified from Tityus serrulatus venom (Tx) induces an increase in volume, acidity and pepsin secretion in the gastric juice of rats. Ligation of oesophagus has been shown to reduce the acid gastric secretion in rats. The aim of this paper was to determine the influence of the esophageal ligation on gastric secretion induced by Tx in rats. METHODS: Forty-four male albino rats were given water ad libitum, but no food for 20 to 24 hours, anesthetized with urethane and the trachea and jugular vein cannulated. Cervical or abdominal esophageal ligation or sham-operations were performed before and after the injection of 0.25 mg/kg of scorpion toxin (fraction Tl) into the jugular vein. One hour later, the volume, acidity, pH and peptic activity of gastric juice were determined. RESULTS: The scorpion toxin induced an increase in gastric juice volume, acidity and pepsin output and a decrease in pH when injected into the vein of intact animals or in sham-operated animals. Cervical esophagus ligation did not interfere with the effects of toxin, however, ligation of the abdominal esophageal decreased the toxin effect on the rat stomach. CONCLUSION: Ligation of the abdominal esophagus decreases the gastric secretion induced by scorpion toxin.

ABSTRACT

OBJETIVO: avaliar a freqüência da utilização de procedimentos cirúrgicos não ginecológicos no tratamento do câncer de ovário, assim como descrever as suas complicações. MÉTODOS: foram incluídas retrospectivamente 82 pacientes, atendidas no período de fevereiro de 1999 a outubro de 2003, e que haviam sido submetidas a laparotomia para tratamento cirúrgico do câncer de ovário. Foram incluídas no estudo apenas pacientes com adenocarcinoma epitelial de ovário. A média de idade foi de 54,1±15,1 anos, variando de 22 a 89 anos. O estadiamento (FIGO) mostrou 5 pacientes no estádio I (6,1 por cento), 18 pacientes no II (21,9 por cento), 40 pacientes no III (48,8 por cento) e 19 pacientes no IV (23,2 por cento). As pacientes foram divididas em 2 grupos: aquelas em que foram realizados exclusivamente procedimentos ginecológicos e aquelas com realização de procedimentos não ginecológicos. As diferenças entre as médias foram analisadas pelo teste t de Student. As comparações entre grupos independentes foram feitas pelo teste do chi2. RESULTADOS: em 35 pacientes (42,7 por cento) foram realizados procedimentos cirúrgicos não ginecológicos, incluindo: 17 colostomias, 16 enterectomias, oito peritonectomias pélvicas, sete colectomias, cinco ressecções parciais de cúpula frênica, quatro cistectomias parciais, quatro esplenectomias, duas ileostomias e uma hepatectomia parcial. Todas as pacientes submetidas a procedimentos não ginecológicos apresentavam-se nos estádios III e IV. Esse grupo apresentou maior tempo cirúrgico (5,3±1,4 versus 3,1±0,9 horas); p<0,001). Os grupos não mostraram diferenças significativas em relação à necessidade de hemotransfusão (42,2 versus 40 por cento; p=0,512) e tempo de internação (11,5±7,2 versus 10±9,9 dias; p=0,454). A realização de procedimentos cirúrgicos não ginecológicos associou-se a maior taxa de complicações pós-operatórias 37 por cento versus (17,1 por cento; p=0,042), sendo que duas pacientes desse grupo (2,4 por cento) evoluíram para o óbito. CONCLUSÕES: os procedimentos cirúrgicos não ginecológicos são freqüentemente empregados no tratamento de pacientes com câncer de ovário. A realização dessas cirurgias está associada a maior tempo cirúrgico e maior taxa de complicações pós-operatórias.

ABSTRACT

The objective of this paper was to develop a clinically relevant abdominal compartment syndrome experimental model, as a single insult and as a second insult flowing hemorrhagic shock. In the single insult model, Sprague-Dawley male-rats are anesthetized, invasively monitored (central venous pressure and mean arterial pressure), and mechanically ventilated during intraperitoneal injection of air to provoke the abdominal compartment syndrome (25 mmHg) for 60 minutes. In the two insult model, Sprague-Dawley male-rats are anesthetized, invasively monitored (mean arterial pressure) and bled to a mean arterial pressure of 30 mmHg for 45 minutes. Fluid resuscitation is accomplished by infusing 0.9 percent sodium chloride solution (0.9 percent NaCl) 33.2 ml/kg plus 75 percent of shed blood volume. During this phase a laparotomy is performed. Two hours after the beginning of the hemorrhagic shock phase the animals are anesthetized, intubated (orotracheal), mechanically ventilated (mean arterial pressure), and the intra-abdominal pressure is increased to 25 mmHg for 60 minutes, as a second insult. A 0.9 percent NaCl solution is infused during this phase (45 ml/kg/h). Hemorrhagic shock and the abdominal compartment syndrome behave as clinically relevant additive insults.

ABSTRACT

The scorpion toxin induces a number of physiological parameters alterations, as disturbance of cardiac rhythm, heart failure, shock, pancreatic hypersecretion, abortion, respiratory arrhytmias and pulmonary edema. As the purification of the venom fractions is a laborious process, one alternative for this would be the utilization of small animals. We utilized in the o present study thity-six mice that received progressive doses of scorpion toxin TsTX), i.p. or i.v., and were observed for three hours or sacrificed, and the pulmonary alterations were determined by the lung-body index and by histological analysis of the lungs in order to determine if the mouse can be an esperimental model for scorpion envenomation. The data were analyzed by One Way analysis of variance with p<0,05 indicating significance. These experiments showed no differences in clinical signs of scorpion envenomation between mice and other mammalians, the effects were dose-dependent and the i.v. administration needed less quantity to produce the same changings. In the pulmonary histology we observed septal but not alveolar edema, and we presumed that these differences are due to species-specific variations.

ABSTRACT

Perianal fistula, usually has a criptoglandular etiology, developing from a perianal abscess and communicating the anal mucosa with the perianal skin. The aim of this paper is to study retrospectively 241 cases of perianal fistula (172 men and 69 women; 2,5:1) aging from 7 and 80 years old (average: 37,4 years), operated on at the Hospital das Clínicas - UFMG, from 1977 to 1996. The surgical techniques and post-operative outcome have been analysed. Perianal abscesses with spontaneous drainage were the predominant etiology (132 patients; 54,8 per cent). Eight percent were submitted to fistulectomy as the first surgical treatment. Among early complications (78; 32,4 per cent), local pain was the most frequent (60; 24,9 per cent). Among the late complications (136; 56,4 per cent) fistula recurrence (101; 41,9 per cent/was the most frequent. There were 141 reoperations in 80 patients. Fistulectomy was the predominant surgical technique employed for the treatment (101; 71,6 per cent). The average hospitalization time was 6,3 days until 1990 and 1,5 day from 1991 to 1996, after the advent of day-surgery beds in HC-UFMG. The surgical treatment of perianal fístula has a significant rate of post-operative complications and a high recurrence rate, in spite of the short stay in hospital.

ABSTRACT

The effects of an intravenous bolus injection of 25 ug x 100 g (-1) b.w. of a purified toxin from the Brazilian scorpion Tityus serrulatus on the rat jejunal absorption and secretion of water, glucose, sodium and chloride were studied in a jejunal loop perfused "in situ" using polyethyleneglycol as a marker, in anesthetized animals. The results seem to indicate that only chloride transport was affected by the toxin as the data analysis have shown a statistically significant increase in the absorption of that ion, while the sodium, glucose and water values before and after toxin remained the same. The addition of toxin into an organ bath containing a segment of jejunum immersed in Tyrode's solution evoked a strong and sustained contraction followed by oscillations of tonus. These effects were resistant even to repeated washings with the bathing solution, but were partially abolished by atropine.

ABSTRACT

Dez pacientes portadores de diverticulo de Zenker foram submetidos a diverticulopexia associada a miotomia do musculo cricofaringeo para tratamento dessa afeccao, entre o periodo de 1983 a 1992. A tecnica consiste na disseccao do diverticulo e ancoramento do mesmo a fascia pre-vertebral de modo a ficar invertido, o que impede o seu enchimento com a degluticao. A media de idade dos pacientes era de 78,8 anos e todos tinham o diagnostico de diverticulo confirmado pela historia clinica e pela radiografia contrastada do esofago. Os sintomas mais comuns eram disfagia e regurgitacao, que foram avaliados no pos-operatorio em todos os pacientes...

ABSTRACT

Camundongos experimentalmente infectados com Schistosoma mansoni foram injetados com tiopental sódico ou antimonial (Triostib R), ou submetidos à inalaçäo de halotano, com ou sem uma injeçäo prévia de tiopental. Os resultados mostraram que o halotano e o tiopental induzem, respectivamente, o deslocamento de 99 e 76% dos vermes para o fígado. Gluconato de sódio e antimônio (Triostib R) deslocou 52% de vermes. Estes resultados parecem indicar que o uso de antimonial seria desnecessário quando se faz a remoçäo cirúrgica de esquistossomos pela técnica de filtraçäo extracorpórea em pacientes com hipertensäo portal
