Inverse-probability weighting and multiple imputation for evaluating selection bias in the estimation of childhood obesity prevalence using data from electronic health records.

Background And Objectives: Height and weight data from electronic health records are increasingly being used to estimate the prevalence of childhood obesity. Here, we aim to assess the selection bias due to missing weight and height data from electronic health records in children older than five.

Methods: Cohort study of 10,811 children born in Navarra (Spain) between 2002 and 2003, who were still living in this region by December 2016.

Is carbohydrates-deficient transferrin the best test of the alcoholic etiology in acute pancreatitis?

Aim: To demonstrate if carbohydrates deficient transferrin (CDT) is the best marker to detect an excessive alcohol consumption as a cause of acute pancreatitis.

Material And Methods: Prospective study of 60 patients consecutively admitted in our hospital. Acute pancreatitis were classified according to their different etiologies, alcoholic (11), probably alcoholic (4), biliary (25) and others (20).

Acute pancreatitis: evaluation of the prognostic criteria of the latest Balthazar tomographic classification.

The use of prognostic criteria to detect potentially acute pancreatitis can allow us to select patients most in need of special attention. Of the many possible criteria, we used Ranson's clinical analytic criteria and Balthazar's tomographic criteria, and compared them to the latest criteria of Balthazar, in which pancreatic necrosis figures as the principal prognostic factor. Tomographic evaluation of pancreatic necrosis was shown to be the best prognostic marker in acute pancreatitis, with the greatest sensitivity and specificity of all methods used with one-hundred consecutive patients admitted with acute pancreatitis.

[Cholestasis caused by Fasciola hepatica].

Human infestation with Fasciola hepatica is observed occasionally. Cholestasis due to parasitic obstruction of the common duct is an infrequent complication. A case of fascioliasis is described in a 56 year-old male with symptoms of biliary colic and biochemical cholestasis.
