24-hour intragastric pH measurement in the assessment of duodenogastric reflux.

In this study we compared the results of measurement of duodenogastric reflux using 24-hour intragastric pH monitoring and nasogastric aspiration with analysis of bile acid and alpha amylase concentrations. Eight patients were studied at least 5 months after biliary and/or gastric surgery. The correlation coefficient of pH and bile acid concentration was 0.36 (p less than 0.001) and of pH and amylase concentration was 0.48 (p less than 0.001). If a pH greater than 4.0 was taken to indicate duodenogastric reflux this had a sensitivity of 84% compared with either high bile acid or amylase concentration. Bile acid concentration has been the "standard" method of measuring duodenogastric reflux. pH monitoring is relatively simple to perform, causes little patient distress, and can measure episodes of duodenogastric reflux over a continuous 24-hour period.

Isotretinoin therapy: any need for laboratory assessment?

BACKGROUND: Recently studies showed the no need for laboratory follow up of patients on isotretinoin therapy. The aim of this study is to assess this issue. PATIENTS AND METHODS: A retrospective study on-400 patients was performed to analyze the laboratory data before and after isotretinoin therapy of acne vulgaris patients. All patients received isotretinoin at a dose of 1mg/kg for 20 weeks. RESULTS: AST was elevated in 25/400(6.25 %), ALT was elevated in 10/400(2.5 %). Cholesterol was elevated in 55/400(13.75%). Triglycerides were elevated in 20/400(5 %). CONCLUSION: This study supports the previous evidence for the no need for performing laboratory investigations for patients on isotretinoin therapy.
