Background The choledocolithiasis has an incidence of 8-20% in patients with cholecystolithiasis. The preoperative diagnosis guides the interventional treatment on the bile duct Aim To evaluate the sensitivity and specificity of the laboratory markers and imaging studies for choledocholithiasis preoperatively.Methods The study comprised 254 patients divided into two groups: the control group (207 patients), patients without choledocholithiasis intraoperatively and cases group (47 patients), that enrolled the patients with choledocholithiasis intra-operatively. Were evaluated the laboratory markers, image exams and intra-operative diagnostic aspects.Results The sample was homogeneous for age and gender. It was observed that 47% of the cases the patients did not show comorbidities. Hospitalization showes in cases group acute pancreatitis in12.8%, jaundice in 30%, fever in 30% and pain in the right hypochondrium in 95%. By comparing them, was observed that fever and jaundice were the signs and symptoms with statistical significance. Patients with choledocholithiasis had transaminases, alkaline phosphatase, gamma-glutamyl transferase and higher bilirubin with statistical significance (p<0.001). In regard to imaging studies, ultrasound was fairly accurate for cholelithiasis and choledocholithiasis (p<0.001).Conclusion Changes in canalicular and transaminase enzymes are suggestive for preoperative choledocholithiasis; GGT showed better sensitivity and alkaline phosphatase greater specificity; ultrasonography and nuclear magnetic resonance cholangiopancreatography showed high specificity.

RESUMOObjetivos: Avaliar a mobilidade funcional e sua relação com a capacidade cognitiva em pacientes com diabetes tipo 2 (DM2) entre 50 e 65 anos de idade, e com menos de 10 anos de diagnóstico. Materiais e métodos: Estudo observacional, analítico e transversal envolvendo indiví-duos não diabéticos e pacientes com DM2 com controle glicêmico inadequado, selecionados por amostra de conveniência. Em ambos os grupos, foram aplicados questionário estruturado, avaliação cognitiva com Miniexame do Estado Mental (MEEM) e teste do relógio (TDR), além da avaliação de mobilidade funcional pelo teste Timed Up & GO (TUG). Resultados: No TUG os pacientes com DM2 apresentaram tempo médio de 11,27 segundos versus 9,52 segundos nos controles (p = 0,013). A associação entre declínio cognitivo e dismobilidade foi positiva nos indivíduos com DM2 (p = 0,037). No subgrupo que apresentou dismobilidade e declínio cognitivo associados, 18% eram portadores de DM2 e 1,6% era do grupo sem DM2 (p < 0,01). Conclusões: Pacientes com DM2 apresentaram pior mobilidade funcional e desempenho cognitivo, favorecendo a hipótese de que o DM2 influencia a mobilidade funcional e capacidade cognitiva antes do aparecimento de complicações vasculares ou neuropáticas. Esses dados sugerem que a hiperglicemia é um fator agravante no desempenho de atividades que exijam funções mentais como atenção, orientação e memória de trabalho.

Materials and methods: An observational, analytical and cross-sectional study, involving no diabetic and type 2 diabetic individuals with inadequate glycemic control, selected by convenience sampling. In both groups, were administered structured questionnaire and cognitive assessment with Mini-Mental State Examination (MMSE) and the clock drawing test (CDT), besides assessment of functional mobility by the Timed Up & Go (TUG). Results: In TUG, DM2 patients presented a mean time of 11.27 seconds versus 9.52 seconds (p = 0.013). The association between cognitive decline and decrease of mobility was positive in individuals with T2DM (p = 0.037). In the subgroup that showed decrease of mobility and associated cognitive decline, 18% were patients with DM2 and 1.6% were individuals without T2DM (p < 0.01). Conclusions: Patients with T2DM presented worse functional mobility and cognitive performance, supporting the hypothesis that DM2 influence functional mobility and cognitive ability, regardless of neuropathic or vascular complications. These data suggest that hyperglycemia is an aggravating factor in the performance of activities requiring mental functions such as attention, working memory and orientation.

There appears to be an association between hyperglycemic status and poorer mobility, with an increased fall risk even in younger patients and in those with shorter disease duration.
