ABSTRACT
OBJECTIVES: The number of pancreatic transplants has decreased in recent years. Pancreatic grafts have been underutilized compared to other solid grafts. One cause of discard is the macroscopic appearance of the pancreas, especially the presence of fatty infiltration. The current research is aimed at understanding any graft-related association between fatty tissue infiltration of the pancreas and liver steatosis. METHODS: From August 2013 to August 2014, a prospective cross-sectional clinical study using data from 54 multiple deceased donor organs was performed. RESULTS: Micro- and macroscopic liver steatosis were significantly correlated with the donor body mass index ([BMI]; p=0.029 and p=0.006, respectively). Positive gamma associations between pancreatic and liver macroscopic and microscopic findings (0.98; confidence interval [CI]: 0.95-1 and 0.52; CI 0.04-1, respectively) were observed. Furthermore, comparisons of liver microscopy findings showed significant differences between severe versus absent (p<0.001), severe versus mild (p<0.001), and severe versus moderate classifications (p<0.001). The area under the receiver operating curve was 0.94 for the diagnosis of steatosis by BMI evaluation using a cut-off BMI of 27.5 kg/m2, which yielded 100% sensitivity, 87% specificity, and 100% negative predictive value. CONCLUSIONS: We observed a positive association of macroscopic and microscopic histopathological findings in steatotic livers with adipose infiltration of pancreatic grafts.

Objetivo: Descrever uma patologia rara, de crescimento lento, com bom prognóstico se adequadamente tratada. Método: Análise e descrição de um caso de mucopiocele fronto-orbitária e transtorno comportamental, submetido ao tratamento cirúrgico no Hospital dos Servidores do Estado do Rio de Janeiro. Resultados: O paciente evoluiu com regressão completa dos sintomas prévios. Conclusão: Nas mucopioceles, os objetivos da cirurgia são: a confirmação do diagnóstico, a drenagem do conteúdo de muco e pus e a excisão ou marsupialização das paredes do cisto e da mucosa do seio comprometido. O diagnóstico correto dessa lesão leva à diminuição da morbidade e mortalidade, em virtude de o tratamento cirúrgico associado à antibioticoterapia venosa ser curativo.
Objective: To describe an uncommon pathology, slow-growing and good prognosis if well treated. Method: Analyze and description of fronto-orbital mucopyocele associated with cognitive impairment submitted a surgical treatment in Hospital dos Servidores do Estado do Rio de Janeiro. Results:Following the surgery all previous symptoms resolved. Conclusion: The objectives of surgery in mucopyoceles are diagnostic confirmation, drainage of secretion, excision or marsupialization of cyst walls and mucous of compromised sinus. The correct diagnosis reduces de morbidity and mortality since the surgical treatment associated with venous antibiotics is curative.
