La anisakiasis es una zoonosis cada vez más prevalente especialmente en países europeos, causada por la ingesta del nemátododel género Anisakis en su tercer estadio larvario tras el consumo de pescado crudo o poco cocido. Puede producir unaafectación gastrointestinal y también una reacción de hipersensibilidad a las proteínas del parasito. Presentamos un caso deanisakiasis gástrica acompañada de hipersensibilidad (forma gastroalérgica) tras la ingesta de pescado crudo.

Objective: To determine the validity of both adenosine diaminase (ADA) test and differential cell count for pleural tuberculosis diagnosis. Design: Retrospective study for diagnosis precision. Setting: Huacho Hospital, Ministerio de Salud, Huacho, Peru. Material: Medical records of patients with ADA test in pleural fluid. Interventions: Medical records study of patients with ADA test in pleural effusion performed from January 2005 through December 2007. ADA test values and differential cell counts were analyzed by ROC curve. Sensitivity (Se), specificity (Sp), predictive values (VPP and VPN) and likehood ratios (LRP and LRN) were found for each variable. Main outcome measures: ADA test cut-off point for pleural tuberculosis diagnosis. Results: Tuberculosis was responsible for most cases of pleural effusion; 47,5 UI/L was the cut-off point by ROC curve, with Se and Sp 73% and 90%, respect...
