ABSTRACT

Biologic drugs represent a substantial progress in the treatment of chronic inflammatory immunologic diseases. However, its crescent use has revealed seldom reported or unknown adverse reactions, mainly associated with anti-tumor necrosis factor (anti-TNF). Psoriasiform cutaneous reactions and few cases of alopecia can occur in some patients while taking these drugs. Two cases of alopecia were reported after anti-TNF therapy. Both also developed psoriasiform lesions on the body. This is the second report about a new entity described as 'anti-TNF therapy-related alopecia', which combines clinical and histopathological features of both alopecia areata and psoriatic alopecia. The recognition of these effects by specialists is essential for the proper management and guidance of these patients.

ABSTRACT

Objetivo: Utilizamos esta pesquisa para estudar e demonstrar que a esofagectomia subtotal através do acesso laparoscópico e transmediastinal para o preparo do estômago, dissecção do esôfago, abdominal e torácico, e cervicotomia esquerda para retirada da peça e anastomose esôfago-gástrica é facultativa e segura no tratamento do megaesôfago avançado. Métodos: Foram realizadas 60 esofagectomias transhiatais por laparoscopia de setembro de 1996 até dezembro de 2006 (10 casos com preservação dos nervos vagos). A idade média dos pacientes foi 56,4 anos (18 – 76) e antes da operação foram submetidos àsorologia para T. cruzi, esofagograma, endoscopia digestiva de alta resolução, eletromanometria, ultrassom de vesícula biliar e pHmetria de 24 horas, avaliação nutricional, fisioterapia respiratória e suporte nutricional através de sonda nasoenteral. As indicações para o tratamento cirúrgico foram: megaesôfago avançado, diagnosticado radiologicamente e manometricamente,recidiva de megaesôfago após operação envolvendo a junção esôfago-gástrica e associação com disfagia acentuada e/ouneoplasia. O acompanhamento foi de 6 a 118 meses. Resultados: Não houve mortalidade, o tempo médio das operações foi de 160 minutos (110 – 325) e houve melhora de todos os parâmetros avaliados. Doze dos 60 pacientes (20%) apresentaram complicações. Ocorreram oito casos de hemopneumotórax (13,34%), três casos de estase gástrica (5%), quatro casos de fístula cervical (6,67%) com resolução clínica e nove casos de disfonia (15%). Conclusão: Os resultados observados na esofagectomia transhiatal laparoscópica foram satisfatórios. Demonstraram que a técnica é segura e traz excelentes resultados pós-operatórios.


Objectives: We studied and demonstrated that the technique of subtotal esophagectomy, through laparoscopic and transmediastinalaccess, in order to prepare the stomach, to dissect the abdominal and thoracic esophagus, and to perform a left cervicotomy for esophageal removal and to proceed with an esophagogastric anastomosis is a good choice and it is a safe method for advanced megaesophagus treatment. Methods: Sixty transhiatal esophagectomies by laparoscopy were performed between September 1996 and December 2006, with preservation of the vagus nerve in the last ten cases. The mean age of the patients was 56.4 yearsold (18-76) and they were submitted to preoperative blood tests for T. Cruzi, esophagography, high-resolution digestive endoscopy,electromanometry, biliary ultrasound, and 24-hour ph-metry. Also a nutritional evaluation, respiratory physiotherapy and enteral nutritional support, using a nasoenteral tube were done. The indications for this surgery were radiologically and functionally advanced megaesophagus, recurrence of megaesophagus after surgery involving the esophageal junction and association of severe dysplasia and/or neoplasia. The follow-up period was from six to 118 months. Results: There was no mortality, the mean surgery time was 160 minutes (110 to 325), and improvement was noted in all evaluated parameters. Twelve of 60 (20%) patients presented with complications; eight cases had hemopneumothorax (13.33%); three cases had gastric stasis (5%); four cases had cervicalfistulae (6.67%), and resolution was achieved with non operative treatment; nine cases had dysphonia (15%). Conclusion: The results observed in laparoscopic transhiatal esophagectomy were encouraging. They demonstrated that this is a practical and safe technique with excellent postoperative results.

ABSTRACT

Various investigators agree that the incidence of cholelithiasis is greater in patients with Chagas disease. The most plausible explanation for this is based on the parasympathetic denervation that occurs over the whole digestive tract due to Chagas disease. In order to analyze the occurrence of this alteration, gallbladder neuron counts were performed on cholelithiasis patients with and without Chagas disease who were being treated at the Department of Digestive Surgery, Universidade Federal do Triângulo Mineiro, Uberaba, Brazil. In the present study, a notable reduction in the number of neurons in the gallbladder wall was observed in Chagas patients, in comparison with non-Chagas subjects.


Vários autores concordam que a incidência de colelitíase encontra-se elevada nos pacientes portadores de doença de Chagas. A explicação mais plausível para este fato baseia-se na desnervação parassimpática existente em todo o tubo digestivo na doença de Chagas. No intuito de analisar a ocorrência desta alteração, foi realizada contagem neuronal da vesícula biliar de pacientes chagásicos e não chagásicos, portadores de colelitíase, tratados na Disciplina de Cirurgia do Aparelho Digestivo, Universidade Federal do Triângulo Mineiro, Uberaba, Brasil. No presente estudo, observou-se uma redução expressiva do número de neurônios na parede da vesícula biliar dos pacientes chagásicos quando comparado com os não chagásicos.

ABSTRACT

PURPOSE: To compare the viability of human hepatocytes dissociated by the ethylenediaminetetraacetic acid and collagenase techniques. METHODS: Hepatocytes were prepared by dissociation of liver fragments obtained from hepatectomies performed for therapeutic purposes at the Service of Digestive Tract Surgery, Federal University of Triângulo Mineiro. RESULTS: During the first 4 days of the experiment, 70 percent of the cells presented birefringent membranes and were not stained with 2 percent erythrosine, and were therefore considered to be viable. During the first 3 days, hepatocyte viability was on average 71 percent in the EDTA group and 76 percent in the collagenase group, with no significant difference between groups. No significant difference was observed between groups at any time. The secretion of albumin by the cultured hepatocytes was preserved up to the seventh day. Mean albumin secretion during the first 3 days was 50 æg/ml in the two groups and a reduction of albumin production was observed from the fourth to the seventh day. Again, no significant difference was observed between groups at any time. CONCLUSION: Cell viability and preservation of albumin secretion by hepatocytes are similar for the EDTA and collagenase techniques.


OBJETIVO: Comparar a viabilidade dos hepatócitos humanos dissociados pelas técnicas do ácido etilenodiaminotetracético e da colagenase. MÉTODOS: Hepatócitos foram preparados pela dissociação de fragmentos de fígado, provenientes de hepatectomias realizadas com o objetivo terapêutico no Serviço de Cirurgia do Aparelho Digestivo da Universidade Federal do Triângulo Mineiro. RESULTADOS: Detectou-se que nos quatro primeiros dias de experimento 70 por cento das células estavam com suas membranas biorrefringentes e não se coravam pela eritrosina a 2 por cento portanto foram consideradas viáveis. Observou-se que nos três primeiros dias a viabilidade dos hepatócitos foi em média 71 por cento no grupo EDTA e 76 por cento na colagenase, diferença esta sem significado estatístico entre os grupos. Em nenhum momento, detectou-se diferença estatística entre os grupos. Com relação a preservação da secreção de albumina pelos hepatócitos em cultura observou-se que foi mantida até o sétimo dia. Da mesma forma, notou-se que nos três primeiros dias a média de secreção de albumina de ambos os grupos foi de 50 ìg/dl e que após o quarto dia verificou-se redução da produção até o sétimo dia. Também não foi observado diferença significativa em nenhum momento entre os grupos. CONCLUSÃO: A viabilidade celular e a preservação da função de secretar albumina pelos hepatócitos são semelhantes pelas técnica do EDTA e da colagenase.

ABSTRACT

Relatamos o caso de um paciente com icterícia obstrutiva cuja causa era colangite esclerosante secundária à síndrome da imunodeficiência adquirida. Na colangiopatia relacionada à síndrome da imunodeficiência adquirida, os pacientes apresentam dor no quadrante superior direito ou epigástrico, febre, diarréia e alterações biliares características. O paciente foi submetido à plastia transversa do ducto hepático comum por via laparoscópica.
