Introduction: most studies narrowly focus on pregnancy outcome comparisons between Wilson's disease (WD) patients on and off treatment. We aimed to identify menses irregularities in untreated WD, and to evaluate pregnancy outcomes in treated WD patients as compared to matched controls (with and without liver disease).

Methods: females with WD, hepatitis C (liver disease controls), and other gastrointestinal conditions (controls without liver disease) were identified at two tertiary hospital gastroenterology departments.

Background And Aims: A recent review of economic studies relating to gastric cancer revealed that authors use different tests to estimate utilities in patients with and without gastric cancer. Our aim was to determine the utilities of gastric premalignant conditions and adenocarcinoma with a single standardized health measure instrument.

Methods: Cross-sectional nationwide study of patients undergoing upper endoscopy (n=1,434) using the EQ-5D-5L quality of life (QoL) questionnaire.

DRESS syndrome (drug rash, eosinophilia and systemic symptoms) is an idiosyncratic drug reaction characterised by rash, fever, lymphadenopathy and internal organ involvement. The authors report a case of this syndrome presenting with fever, generalised pruritus, macular rash and cholestatic hepatitis during allopurinol treatment. This case resolved with drug withdrawal, but the death rate in the setting of hepatic failure can reach 10%.

Background/aims: good colonic preparation is essential to perform a complete and safe colonoscopy. The preparation used in the Endoscopy Unit was adopted after testing it against the classic 4-liter polyethylene glicol (PEG) preparation (Klean-Prep). Recently a new 3-liter PEG preparation was commercialised in Portugal, Endo-Falk, which appeared to be simpler and effective.
