Irritable bowel syndrome in Indonesian adolescents

Abstract Objective: Irritable bowel syndrome is a frequent functional gastrointestinal disorder. The aims of this study were to investigate its epidemiology, focusing on the role of intestinal mucosal integrity and to evaluate the impact on the quality of life. Methods: A community-based survey applying a comparative cross sectional approach was conducted in six high schools in Palembang. Subjects were recruited using multistage random sampling divided in two groups. Rome III criteria were used to establish a diagnosis of IBS in combination with a questionnaire to determine risk factors. Determination of fecal alpha-1-antitrypsin and calprotectin levels was performed to determine impaired intestinal mucosal integrity. A questionnaire was used to evaluate how quality of life was affected by irritable bowel syndrome. Results: The survey was performed in 454 14−18 years old adolescents, of whom 30.2% fulfilled the Rome III criteria for IBS, with the following subtypes: 36.5% diarrhea, 18.9% constipation, 21.9% mixed, and 22.6% unclassified. Major risk factors were female gender, bullying, age 14-16 years, history of constipation and diarrhea, eating nuts, and drinking coffee, tea, and soft drinks. There was a significant association with intestinal inflammation (p = 0.013). A significantly impaired quality of life was found (p = 0.001). Conclusions: The prevalence of irritable bowel syndrome in adolescents was high, with bullying, female gender, age 14-16 years, constipation and diarrhea, and dietary consumption of soft drinks, coffee, and tea as risk factors. A significant association with intestinal inflammation was found.

Evaluation of the stability of Cell Dyn 16 Tri Level as a control material for laboratory external quality assessment scheme on hematology.

The implementation of a laboratory test should always implement a laboratory quality control program, i.e internal quality control and external quality assessment. In an external quality assessment scheme, a control material that is stable over delivery until tested by the participating laboratory. In this study, we evaluated the stability of Cell Dyn 16 Tri Level (TL) control material at room temperature (26-32 degrees C), stored in a transport vessel containing ice pack, and the precision and accuracy of the instrument Cell Dyn 1400. The control used was Cell Dyn 16 TL with low value (L), normal value (N) and high value (H). This study was done in the Clinical Pathology Department of FKUI-RSCM during February 2001 until May 2001. Control material was stored room in a transport vessel containing ice pack for 15 days, then analysed macroscopically, microscopically and evaluated for its stability. Test for precision and accuracy was done within run and for precision between day on Cell Dyn 1400. The result of this study showed a macroscopic change beginning on day 14 (L) day 12 (N) and day 15 (H). Microscopic change was observed on day 13 (L and N) and day 15 (H), Erythrocyte and hemoglobin level was stable until day 15. Changes in leukocyte was seen on day 14 (L), day 12 (N) and day 15 (H). Platelet showed instability on day 9 (L), day 10 (N and H). Mean erythrocyte volume was out of range on day 15 (L), but the N and H control was still stable. The precision and accuracy of Cell Dyn 1400 was in WHO recommended range. We concluded that the precision and accuracy of Cell Dyn 1400 is good. Cell Dyn 16 TL control material was stable until day 9, and its can be recommended to be used as a control material for external quality assessment scheme.
