RESUMO
PURPOSE: Dopamine agonists (DA) are the gold-standard for prolactinoma and hyperprolactinemia treatment. Intolerance to DA leading to drug drop out occurs in 3 to 12% of cases. We provide here a review of published data about DA intolerance and present a case report concerning the use of intravaginal cabergoline. METHODS: We review the literature on the definition, the pathogenesis, frequency and management of DA intolerance. In addition, the review provides strategies to enhance tolerability and avoid precocious clinical treatment withdrawal. RESULTS: Cabergoline is often cited as the most tolerable DA and its side effects tend to ameliorate within days to weeks. Restarting the same drug at a lower dose or switching to another DA can be used in cases of intolerance. The vaginal route can be tried specifically if there are gastrointestinal side effects in the oral administration. Symptomatic treatment could be attempted, although mainly based on a strategy used in other diseases. CONCLUSIONS: Due to limited data, no guidelines have been developed for the management of intolerance in DA treatment. The most frequent management is to perform transsphenoidal surgery. Nevertheless, this manuscript provides data derived from published literature and expert opinion, suggesting new approaches to this clinical issue.

An enlarging thyroid normally extends into the mediastinum, resulting in a presternal or substernal goiter, depending on its migration anteriorly or posteriorly, respectively. The first one was a rare entity in medical literature, being previously reported in only 6 cases worldwide. The present case reports a 54-year woman with a presternal goiter. She had a history of partial thyroidectomy due to a colloid goiter in 2004. Her thyroid function revealed subclinical hypothyroidism. No other abnormalities were present in physical exam or in laboratory tests. A resection of the remaining thyroid tissue was made, with great postsurgical recovery. The anatomopathological study revealed a colloid goiter. Such case porpoise is to remember physicians that unusual presentations of ordinary diseases can occur. This report differs on literature, which demonstrated that papillary thyroid carcinoma is the most important cause of presternal goiter. Moreover, unlike previous reports with normal thyroid function, this case is the only one reported with subclinical hypothyroidism.

Hypertriglyceridemia is the third most common cause of acute pancreatitis. Among the causes that lead to secondary hypertriglyceridemia, the use of contraceptive agents is the main reason to be assessed in young women. We report a case of a 31-year-old woman who had suffered two acute pancreatitis episodes secondary to hypertriglyceridemia. In the investigation, the previous medical team indicated a genetic screening before ruling out all secondary causes. LPL, apo CII and apo AV genes were negative for mutations. In the first appointment with us, the patient reported the use of a contraceptive agent for about 2 years. She was instructed to discontinue the drug. After one year of follow-up, her serum triglycerides are within the normal range and a copper intrauterine device was the method chosen by the patient for contraception.

Os aneurismas de artéria poplítea correspondem a 70% dos aneurismas periféricos e o tratamento é cirúrgico, com controvérsias sobre os resultados da via endovascular. Este estudo objetivou realizar uma revisão da literatura sobre a comparação entre cirurgia aberta e endovascular no tratamento dos aneurismas da artéria poplítea. A pesquisa foi realizada utilizando os termos apropriados nos portais de periódicos LILACS e MEDLINE, com a seleção de 15 artigos. Um total de 5.166 procedimentos cirúrgicos foram comparados, sendo 3.930 cirurgias abertas e 1.236 cirurgias endovasculares. A cirurgia aberta com bypass venoso continua sendo o padrão-ouro. A cirurgia endovascular apresenta menor tempo de internação e é uma opção viável em pacientes eletivos, com baixa expectativa de vida, alto risco cirúrgico, comorbidades e mais idosos, desde que tenham anatomia favorável para o procedimento. Contudo, são necessários estudos de longo prazo para estabelecer os reais benefícios e indicações das duas técnicas, como o ensaio clínico randomizado controlado
Popliteal artery aneurysms account for 70% of peripheral aneurysms and must be treated surgically. The results of endovascular treatment are controversial. The objective of this study is to conduct a literature review on comparisons between open surgery and endovascular treatment for popliteal artery aneurysms. Searches were run on the LILACS and MEDLINE databases using the appropriate search terms and 15 articles were selected. A total of 5,166 surgical procedures were compared, 3,930 open surgeries and 1,236 endovascular surgeries. Open surgery with venous bypass is still the gold standard. Endovascular surgery offers shorter length of hospital stay and is a viable option for elective patients, those with short life expectancy, high surgical risk, comorbidities, and more advanced age. However, long-term studies are needed to establish the true benefits and indications for the two techniques, such as randomized clinical trials

Avaliar se uma intervenção educacional interfere na adesão ao tratamento, meta terapêutica e frequência de eventos hemorrágicos de pacientes em uso de antagonistas de vitamina K e se características socioeconômicas/clínicas possuem efeito sobre os resultados encontrados. Método: Estudo analítico intervencionista não controlado qualitativo. Foram incluídos 49 pacientes e aplicados os questionários de medida de adesão ao tratamento (MAT) e socioeconômico. Posteriormente foram realizadas ligações mensais educativas sobre anticoagulação e foram coletadas informações sobre eventos hemorrágicos e valores de RNI. Ao termino da intervenção foi aplicado mais um questionário MAT. Foram comparados os dados antes e após a intervenção. Resultados: Os pacientes foram considerados mais aderentes após a intervenção (p=0,04) e houve diminuição na frequência de eventos hemorrágicos (p=0,01), existindo nenhuma relação com as variáveis socioeconômicas ou clínicas. Não houve melhora significativa em relação à meta de RNI (p=0,06), porém o estado civil desses pacientes teve associação com a estabilidade terapêutica (p=0,04). Conclusões: A intervenção melhorou a aderência e diminuiu os eventos hemorrágicos dos pacientes, não tendo influência sobre a meta terapêutica. Pacientes com cônjuge apresentaram melhores metas terapêuticas se comparados aos solteiros. Não houve interferência de outras variáveis socioeconômicas ou clínicas sobre os desfechos encontrados
Objectives: To evaluate if an educational intervention interfere in treatment adherence, therapeutic ranges and hemorrhagic.events of patients on vitamin K antagonists; and if social, economic and clinical.characteristics are associated with the ending points. Methods: It's an interventionist analytic study. 49 patients were included.and an adherence.and social/economic questionnaires were applied. Then, monthly educative phone calls.were performed about anticoagulation and information about hemorrhagic,events and INR were collected. When intervention,were done, another adherence questionnaire was applied. Data before and after intervention were compared. Results: Patients had their adherence improved (p=0,04) and there was a fall on the prevalence,of hemorrhagic events (p=0,01) with,no,social/clinical variables association. There were no significant,changes,on the therapeutic ranges (p=0,06), although there was a relationship,between marital state and INR,stability (p=0,04). Conclusions: Educational intervention increased adherence,and decreased hemorrhagic events. Marital state has been associated with better therapeutic,ranges. No other social, economic.or clinical.variable has been associated with the ending points
RESUMO
BACKGROUND: Due to the increased prevalence of obesity in many countries, the number of bariatric surgeries is increasing. They are considered the most effective treatment for obesity. In the postoperative there may be difficulties with the quality of alimentation, tolerance to various types of food, as well as vomiting and regurgitation. Few surveys are available to assess these difficulties in the postoperative. AIM: To perform a systematic literature review about food tolerance in patients undergoing bariatric surgery using the questionnaire "Quality of Alimentation", and compare the results between different techniques. METHOD: A descriptive-exploratory study where the portals Medline and Scielo were used. The following headings were used in english, spanish and portuguese: quality of alimentation, bariatric surgery and food tolerance. A total of 88 references were found, 14 used the questionnaire "Quality of Alimentation" and were selected. RESULTS: In total, 2745 patients were interviewed of which 371 underwent to gastric banding, 1006 to sleeve gastrectomy, 1113 to Roux-en-Y gastric bypass, 14 to biliopancreatic diversion associated with duodenal switch, 83 were non-operated obese, and 158 non-obese patients. The questionnaire showed good acceptability. The biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to other techniques, but it was evaluated in a single article with a small sample. The longer the time after the operation, the better is the food tolerance. Comparing the sleeve gastrectomy and the Roux-en-Y gastric bypass, there are still controversial results in the literature. The gastric banding had the worst score of food tolerance among all the techniques evaluated. CONCLUSION: The questionnaire is easy and fast to assess the food tolerance in patients after bariatric surgery. Biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to sleeve gastrectomy and the Roux-en-Y gastric bypass. Gastric banding still remains in controversy, due it presented the worst score.

Introdução: Devido ao aumento da prevalência da obesidade em diversos países, o número de operações bariátricas está aumentando. Elas são consideradas o tratamento de maior eficácia da obesidade. No pós-operatório podem ocorrer dificuldades com relação à qualidade da alimentação, tolerância para vários tipos de alimentos, além de vômito e regurgitação. Poucos questionários estão disponíveis para avaliar essas dificuldades no pós-operatório.Objetivo: Realizar revisão sistemática da literatura sobre a tolerância alimentar em pacientes submetidos à cirurgia bariátrica utilizando o questionário "Quality of Alimentation" e comparar os resultados entre as diferentes técnicas.Método:Estudo descritivo-exploratório onde foram pesquisados os portais de periódicos Medline e Scielo. Utilizaram-se os descritores "quality of alimentation, bariatric surgery e food tolerance", em inglês, português e espanhol. Foram encontradas 88 referências, sendo 14 selecionadas por utilizarem o questionário "Quality of Alimentation".Resultados: Ao total, 2745 pacientes foram entrevistados sendo que 371 foram submetidos à bandagem gástrica, 1006 à gastrectomia vertical, 1113 ao bypass gástrico em Y-de-Roux, 14 à derivação biliopancreática associada ao duodenal switch, 83 eram obesos não operados, e 158 pacientes não obesos. O questionário teve boa aceitação. A derivação biliopancreática com duodenal switch apresentou a melhor tolerância alimentar no pós-operatório quando comparada às demais técnicas, mas foi avaliada em um único artigo e com pequena amostra. Quanto maior o tempo de pós-operatório, melhor foi a tolerância alimentar. Comparando a gastrectomia vertical e o bypass gástrico em Y-de-Roux, ainda há resultados controversos na literatura. A banda gástrica apresentou o pior escore de tolerância alimentar dentre todas as técnicas avaliadas.Conclusão: O questionário é de fácil e rápida aplicação para avaliar a tolerância alimentar em pacientes submetidos à cirurgia bariátrica. A derivação biliopancreática com duodenal switch teve a melhor tolerância alimentar no pós-operatório quando comparada à gastrectomia vertical e ao bypass gástrico em Y-de-Roux. Quanto à banda gástrica ainda existe controvérsia quanto ao seu uso, devido à apresentação de piores resultados.
