RESUMO
\ The fetal biparietal diameters (BPD) between 12th and 40th weeks were measured by two ultrasonologists, using a Hitachi model 50 A, at Srinagarind Hospital during October 1987-March 1990.\ The measurements that were confirmed gestational age by paediatricians after births were 565 occasions in 409 newborns.\ The gestational ages were based on the history of the last menstrual period and the correlated fundal height.\ No medical, surgical or obstetrical complication was found during these pregnancies.\ The mean increase in the BPD between the 12th and 28th weeks, the 29th and 35th weeks, the 36th and 39th weeks were 3.16 0.9, 1.95 1.2 and 0.61 0.6 mm./mk. respectively.\ The growth of BPD in this study followd the curves similar to those in Western countries in the third trimester.\ The growth of BPD in this study compared with in country study was similar to Chula\’s study but it was more than Health Promotion Center 4\’s study.\
RESUMO
Background: Thiamine requirement is increased in sick children while their food intake are decreases. Studies from western countries had reported that thiamine deficiency is common in pediatric patients with potentially fatal consequences. There have been no previous studies on thiamine status in pediatric patients in Thailand.Objective: To determine the incidence and factors related to thiamine deficiency in sick children admitted to hospital for mote than two weeks.Design: Srinagarind Hospital, Faculty of Medicine, Khon Kaen UniversitySubjects: Twenty four cases of sick children who first admitted to pediatric wards for more than two weeks between December 1994 and November 1995.Measurements: Thiamine status was determined by assessing the erythrocyte transketolase enzyme activity and the thiamine pyrophosphate effect in red blood cells.Results: Seven (29.2%) patients had thiamine deficiency, 2 (8.3%) patients had low level, and 15 (62.5%) patients had normal level. Most of the thiamine deficiency patients had malignancies but a normal nutritional status, by anthropometric assessment.Conclusions: Thiamine deficiency may occur even in patients with a normal nutritional status without presenting any signs of deficiency. A definite diagnosis requires biochemical assessment. Because thiamine deficiency is potentially fatal, thiamine supplementation should be considered.
RESUMO
Background : The content in the comprehensive examination which is the graduation exam for the KKU medical students has to be the minimal essential knowledge. The post-test item analysis will be able to reflect this qualification of the test examination for further development.Objective :To assess the overall reliability—as well as the difficulty index and discrimination power for all the questions—of two MCQ exam papers (150 items/paper) used as comprehensive examinations for 6th-year clinical sciences by medical students at Khon Kaen University, Thailand.Design : Descriptive studySubjects : 300 MCQ items of the comprehensive examination for the 6th-year Khon Kaen Medical studentsResults : Most of the questions were of a ‘moderate’ to an ‘easy’ degree of difficulty, corresponding to the objective of the comprehensive exam, which is to assess the minimal but essential knowledge of medical students before they can graduate. Notwithstanding, the overall reliability of each paper was low compared to the recommended values for summative evaluations (i.e. \>0.7 for a teacher prepared test and 0.9 for a standardized test). Conclusion : This assessment will be used as a guideline by the Comprehensive Examination Committee to improve the quality of future tests. Additionally, since we analysed the achievement of the students in different disciplines, this baseline data can also be used as a feedback for each Department when reviewing the curriculum, setting teaching objectives and improving the learning context.
