Anesthesia for bariatric surgery in patient with mitochondrial myopathy - case report.

Mitochondrial Myopathy is a rare pathology caused by a defect in the mitochondrial DNA metabolism, leading to defects in the formation of adenosine triphosphate, in the Krebs citric acid cycle, fatty acid oxidation and oxidative phosphorylation. It is manifested by exercise intolerance, muscle fatigue on small efforts, muscle weakness, tachycardia, and difficulty breathing. There are few case reports on the operative management of adult patients suffering from mitochondrial myopathy. With this report, we intend to describe the anesthetic management of a patient with mitochondrial myopathy who underwent laparoscopic gastroplasty and outline some anesthetic considerations about this pathology.

RISK FACTORS ASSOCIATED WITH HEPATIC ARTERY THROMBOSIS: ANALYSIS OF 1050 LIVER TRANSPLANTS.

BACKGROUND: Hepatic artery thrombosis is an important cause of graft loss and ischemic biliary complications. The risk factors have been related to technical aspects of arterial anastomosis and non-surgical ones. AIM: To evaluate the risk factors for the development of hepatic artery thrombosis. METHODS: The sample consisted of 1050 cases of liver transplant. A retrospective and cross-sectional study was carried out, and the variables studied in both donor and recipient. RESULTS: Univariate analysis indicated that the variables related to hepatic artery thrombosis are: MELD (p=0.04) and warm time ischemia (p=0.005). In the multivariate analysis MELD=14.5 and warm ischemia time =35 min were independent risk factors for hepatic artery thrombosis. In the prevalence ratio test for analysis of the anastomosis as a variable, it was observed that patients with continuous suture had an increase in thrombosis when compared to interrupted suture. CONCLUSIONS: Prolonged warm ischemia time, calculated MELD and recipient age were independent risk factors for hepatic artery thrombosis after liver transplantation in adults. Transplanted patients with continuous suture had an increase in thrombosis when compared to interrupted suture. Re-transplantation due to hepatic artery thrombosis was associated with higher recipient mortality.

A cohort study among 402 patients with penile cancer in Maranhão, Northeast Brazil with the highest worldwide incidence.

OBJECTIVE: Maranhão State-Northeast Brazil-has the world's highest incidence of penile cancer. This study describes the epidemiological, histopathological and clinical profile of patients stricken across that Brazilian state. The study is aimed at providing new data on neoplasia. DATA DESCRIPTION: 402 men stricken with penile cancer were studied from January 2004 to December 2018. A retrospective stage was developed with collection of physical and electronic records. A prospective stage was performed with collection of clinical and epidemiological information through a questionnaire. The surgical material was looked into by a uropathologist, and the lesions were evaluated for macroscopic characteristics and various microscopic parameters. Three articles using this data have already been published.

Profile of patients with penile cancer in the region with the highest worldwide incidence.

To determine the epidemiological, histopathological, and clinical characteristics of patients diagnosed with penile cancer in the Brazilian state of Maranhão, the region with the highest incidence worldwide. One hundred and sixteen penile cancer patients were interviewed from July 2016 to October 2018. The majority of patients lived in a rural area (57%), worked in farming (58%), had a low level of schooling or no schooling (90%), and were married or in a stable relationship (74%). The mean age was 60.4 ± 16.51 years (range, 23-93 years). Phimosis (66%), poor/moderate genital hygiene (73%), history of sexually transmitted infections (55%), and zoophilia (60%) were found in the majority of patients. Most patients had their first sexual encounter at 16.2 ± 2.8 years (range, 10-25 years), and 75% had >6 sexual partners. The most common initial symptom was pruritus (37%), and most patients waited to seek treatment (average time to treatment, 18.9 months; range, 2-84 months). Human papillomavirus (HPV)-related histologies were observed in 62% of patients. Most patients had histological grades II or III (87%), stage ≥T2 disease (84%), and lymphadenopathy at admission (42%). Penectomy was performed in 96% of patients. The population with penile cancer in the region of highest incidence in the world is marked by low socioeconomic status, high prevalence of HPV infection, and phimosis. The delay in seeking treatment is related to a very high rate of advanced cancer and aggressive surgical treatment. The high prevalence of young patients was also a striking feature.

RESUMO Racional: Trombose de artéria hepática é importante causa de falência de enxerto e complicações biliares. Fatores de risco para trombose estão relacionados aos aspectos técnicos da anastomose arterial e fatores não cirúrgicos. Objetivo: Avaliar os fatores de risco para o desenvolvimento de trombose de artéria hepática. Métodos: A amostra consta de 1050 casos de transplante hepático. Foi realizado estudo retrospectivo e transversal, e as variáveis foram avaliadas em doadores e receptores. Resultados: A análise univariada mostrou que as variáveis relacionadas a trombose de artéria hepática são: MELD e tempo de isquemia quente. Na análise multivariada, o MELD=14.5 e tempo de isquemia quente =35 min foram fatores de risco independentes para trombose de artéria hepática. No teste de prevalência para avaliação do tipo de anastomose como variável, foi observado que a sutura contínua tem maior risco de trombose quando comparada com aquela em pontos separados. Conclusão: Tempo de isquemia quente prolongado, MELD calculado e idade do recipiente foram fatores de risco independentes para trombose de artéria hepática após transplante de fígado em adultos. Pacientes submetidos à anastomose com sutura contínua apresentaram mais trombose quando comparados com a em pontos separados. Retransplante por trombose está associado com maior mortalidade.

Anesthesia for surgical repair of the pentalogy of Cantrell: case report / Anestesia em cirurgia para correção de pentalogia de Cantrell: relato de caso

Abstract Pentalogy of Cantrell is a congenital anomaly associated with defects in the abdominal wall, sternum, diaphragm, and diaphragmatic pericardium formation, in addition to the development of cardiac abnormalities. It is a rare disease with an estimated incidence of one case for every 65,000 births, being more common in males (60% of cases). It has a reserved prognosis with mortality around 63%, and a maximum of 9 months survival after surgery. There are few case reports addressing the pentalogy of Cantrell, which is justified by the rarity of this pathology. In this report our objective was to describe a surgical case of a female patient and make some anesthetic considerations about this rare congenital malformation.

Resumo A pentalogia de Cantrell é uma anomalia congênita associada a defeitos na formação da parede abdominal, do esterno, diafragma e pericárdio diafragmático, além do desenvolvimento de anomalias cardíacas. É uma doença rara, com incidência estimada em um caso para cada 65.000 nascimentos, mais comum no sexo masculino (60% dos casos). Apresenta prognóstico reservado com mortalidade em torno de 63% e sobrevida após procedimento cirúrgico de no máximo nove meses. São escassos os relatos de casos referentes à pentalogia de Cantrell, o que se justifica pela raridade dessa patologia. Com este relato, os autores objetivam descrever um caso cirúrgico, em paciente do sexo feminino, e tecer algumas considerações anestésicas sobre essa malformação congênita rara.

Intubação de via aérea difícil em paciente com síndrome de Treacher Collins / Difficult airway intubation in a patient with Treacher Collins syndrome - case report

A síndrome de Treacher Collins é uma patologia rara, com gene causador mapeado no braço longo do cromossomo cinco (5q31. 3-q33.3). Conhecida como disostose craniofacial, apresenta-se com hipoplasia malar, hipoplasia mandibular e malformações do pavilhão auricular. Tal condição representa previsão de dificuldade para o ato anestésico de intubação, necessitando de avaliação pré-operatória minuciosa e cuidado intensivo no perioperatório. A anestesia geral costuma ser realizada por indução de anestésicos inalatórios, uma vez que crianças submetidas a procedimentos cirúrgicos são não cooperativas, além de haver dificuldade de se obter acesso venoso. Assim, objetiva-se relatar caso de via aérea de intubação difícil em paciente com síndrome de Treacher Collins, correlacionando às manifestações clínicas, ao diagnóstico e ao tratamento cirúrgico, e revisando a literatura sobre o tema. Relatamos um caso cuja singularidade reside no manejo anestésico diferente dos executados em outros centros médicos, ao abordar pacientes com previsão de via aérea difícil. Ao invés de se utilizar máscara laríngea ou intubação com laringoscópio óptico, procedeu-se a: indução inalatória, sedação sem abolir respiração espontânea, visualização das estruturas para introdução do tubo endotraqueal (Cormack 3), acesso venoso, intubação orotraqueal e, posteriormente, indução anestésica e bloqueio neuromuscular. Julgamos importante divulgar tal relato para expor alternativas na indisponibilidade de certos dispositivos, como o fibroscópio. A técnica de intubação sem máscara laríngea ou fibroscópio em pacientes com síndrome craniofacial pode ocorrer sem intercorrências com a estratégia de não abolir a respiração do paciente, porém com leve sedação, devido à não cooperação e à dificuldade de se obter acesso venoso em crianças.

Treacher Collins syndrome is a rare disease with the culprit gene mapped on the distal long arm of chromosome five (5q31. 3-q33.3). It is known as craniofacial dysostosis, and presents with malar hypoplasia, mandibular hypoplasia, and pinnae malformations. Such condition represents expected difficult airway intubation during anesthesia, requiring detailed preoperative evaluation, and intensive perioperative care. General anesthesia is usually performed through inhaling anesthetics because children undergoing surgical procedures are not cooperative, and their venous access is difficult. Thus, the aim of the study is to report a case of difficult airway intubation in a patient diagnosed with Treacher Collins syndrome, correlating clinical manifestations, diagnosis e surgical treatment, and reviewing the literature on the subject. We report a case that is unique because the anesthetic management is different from what has been done in other medical centers, since it manages patients with expected difficult airway. Instead of using a laryngeal mask airway (LMA) device or a flexible optical intubation (FOI), an inhaling induction was performed, with preserved spontaneous breathing sedation, and visualization of the structures to receive the endotracheal tube (Cormarck 3), venous access, orotracheal intubation and then, anesthetic induction and neuromuscular block. We consider it important to share this report to give alternatives when some devices, such as the fiberscope, are not available. The intubation technique without laryngeal mask airway device or fiberscope in patients with craniofacial syndrome may take place with no complications, when the patient's spontaneous breathing is not aborted, but with light sedation, because of children's noncooperation, and difficulty venous access.
