Knowledge of tuberculosis among medical professionals and university students in Oman.

This study in Oman investigated knowledge about tuberculosis among 142 medics (medical students, paramedics) and 133 non-medics (arts and social science students). Knowledge was assessed using a validated questionnaire with 28 statements on general knowledge, risk factors and diagnosis of tuberculosis. As expected, tuberculosis knowledge was significantly higher among medics but there was no significant difference between men and women. Although medics had better knowledge in general, some of the technical statements were answered correctly by higher proportions of non-medics.

Rehabilitation outcomes of cardiac and non-cardiac anoxic brain injury: a single institution experience.

OBJECTIVE: To compare the functional outcomes of patients with anoxic brain injury (ABI) due to cardiac and non-cardiac aetiologies. DESIGN: Retrospective chart review over 4 years. SETTING: Freestanding rehabilitation hospital. PARTICIPANTS: Thirteen patients with cardiac ABI and 13 patients with non-cardiac ABI. INTERVENTION: Comprehensive, multi-disciplinary inpatient rehabilitation services. MAIN OUTCOME MEASURES: Rehabilitation hospital length of stay (LOS) and cost; Functional Independence Measure (FIM) scores and its various sub-sets on admission and discharge; FIM efficiency and change; and discharge disposition. RESULTS: Patients with cardiac ABI were similar in gender and ethnicity when compared to patients with non-cardiac ABI but were older (average age 52 vs 42) with a higher percentage of cardiac patients married (77% vs 39%). No statistically significant differences were found between the two groups on all sub-sets of the FIM on admission and discharge as well as the different FIM efficiencies. However, there was a trend for the cardiac ABI patients to have a greater efficiency in improving mobility during rehabilitation when compared to non-cardiac ABI patients. The rehabilitation hospital LOS was approximately 28 days less for patients with cardiac ABI (41.49 vs 69.84 days), but this difference was not statistically significant (p=0.26). The mean rehabilitation cost for patients with cardiac ABI was approximately $14,000 less than that for those with non-cardiac ABI ($44,181 vs $58,187). This difference was not statistically significant (p=0.15). Cardiac ABI patients were more likely to be discharged directly to home from rehabilitation when compared to non-cardiac ABI patients (p=0.06). CONCLUSION: This pilot study demonstrates some differences in the recovery patterns of patients with ABI who had a cardiac aetiology and those who had non-cardiac aetiologies. While both groups experienced similar progress during rehabilitation, those with cardiac ABI made gains with a shorter LOS and less rehabilitation costs when compared to non-cardiac ABI patients. These data suggest a trend towards greater cost and length of stay for patients with ABI who had non-cardiac aetiologies.

A survey of anorexia nervosa using the Arabic version of the EAT-26 and "gold standard" interviews among Omani adolescents.

OBJECTIVE: The purpose of this study was to assess the validity of the Eating Attitude Test (EAT) in identifying the presence and severity of eating pathology in male and female Omani urban adolescents and to establish cut-off scores that matched those of anorexia identified by gold standard interviews without fear of fatness criteria. METHODS: Both females (n=126) and males (n=136) were screened using the Arabic version of the EAT-26 and interviewed using a semi-structured, Composite International Diagnostic Interview (CIDI) in order to investigate the relationship between false positives and false negatives at various EAT-26 cut-off points. A receiver operating characteristics (ROC) curve was calculated to discriminate the power of the EAT-26 for every possible threshold score. RESULTS: The EAT-26 identified 29% of the subjects as probable anorexic cases as against 9.5% identified during the structured interview based on the anorexia gold standard (32% males and 68% females). The sensitivity and specificity of the EAT-26 were respectively 24% and 69.6%. When using the ROC curve, a cut-off score of 10 gave the best compromise between sensitivity (64%) and specificity (38%). DISCUSSION: Although the EAT-26 is the most widely used screening instrument in cross-cultural studies, it does not appear to be reliable in identifying probable cases of anorexia among Omani adolescents. The use of a gold standard interview without fat phobia criteria indicated that the rate of anorexia nervosa may be more prevalent among males than previously estimated. This intriguingly high preponderance of males is discussed in terms of prevailing demographic trends in Oman.
