Thermal insulation and clothing area factors of typical Arabian Gulf clothing ensembles for males and females: measurements using thermal manikins.

The thermal insulation of clothing is one of the most important parameters used in the thermal comfort model adopted by the International Standards Organisation (ISO) [BS EN ISO 7730, 2005. Ergonomics of the thermal environment. Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria. International Standardisation Organisation, Geneva.] and by ASHRAE [ASHRAE Handbook, 2005. Fundamentals. Chapter 8. American Society of Heating Refrigeration and Air-conditioning Engineers, Inc., 1791 Tullie Circle N.E., Atlanta, GA.]. To date, thermal insulation values of mainly Western clothing have been published with only minimal data being available for non-Western clothing. Thus, the objective of the present study is to measure and present the thermal insulation (clo) values of a number of Arabian Gulf garments as worn by males and females. The clothing ensembles and garments of Arabian Gulf males and females presented in this study are representative of those typically worn in the region during both summer and winter seasons. Measurements of total thermal insulation values (clo) were obtained using a male and a female shape thermal manikin in accordance with the definition of insulation as given in ISO 9920. In addition, the clothing area factors (f cl) determined in two different ways were compared. The first method used a photographic technique and the second a regression equation as proposed in ISO 9920, based on the insulation values of Arabian Gulf male and female garments and ensembles as they were determined in this study. In addition, fibre content, descriptions and weights of Arabian Gulf clothing have been recorded and tabulated in this study. The findings of this study are presented as additions to the existing knowledge base of clothing insulation, and provide for the first time data for Arabian Gulf clothing. The analysis showed that for these non-Western clothing designs, the most widely used regression calculation of f cl is not valid. However, despite the very large errors in f cl made with the regression method, the errors this causes in the intrinsic clothing insulation value, I cl, are limited.

Knowledge, attitudes and practices of secondary-school pupils in Oman: I. health-compromising behaviours.

We investigated the practice of some of health-compromising behaviours among Omani adolescents and their correlates in a nationally representative secondary school-based sample of 1670 boys and 1675 girls. The mean age of the sample was 17.13 (SD 1.35) years. Through a self-administrated questionnaire the adolescents were asked about 6 risky behaviours: current smoking, ever use of alcohol, succumbing to peer pressure to take illicit drugs, driving without a licence, speeding while driving and being involved in a physical fight in the month prior to the survey. Demographic and psychosocial variables related to their risk behaviours were also assessed. The results indicated that 4.6 % were current smokers, 4.3% had drunk alcohol and 4.6% had taken drugs. About 20% had been involved in a physical fight in the month prior to the survey, 33.4% drove without a licence and 33.9% liked to speed. Male sex and low self-esteem were the strongest predictors of risky behaviour.

Knowledge, attitudes and practices of secondary-school pupils in Oman: II. reproductive health.

We examined the knowledge, attitudes and practices of Omani adolescents with regard to reproductive health in a nationally representative secondary school-based sample of 1670 boys and 1675 girls. Through a self-administrated questionnaire the adolescents were asked about puberty, marriage, birth spacing and AIDS and sexually transmitted infections. Only half of the sample knew the changes at puberty of their own sex, while even fewer knew the changes in the opposite sex. Girls were inclined significantly towards later age of marriage than boys. The mean number of children desired by the sample was 4.9. About two-thirds of the adolescents had a positive attitude toward modern contraceptive methods and intended to use them in the future. Knowledge of fertility period was poor as was knowledge of AIDS and sexually transmitted infections. There was a high rate of approval (80%) of female genital cutting by both sexes.

[Repeat suicide attempts: characteristics of repeaters versus first-time attempters admitted in the emergency of a Tunisian general hospital]. / Les récidives suicidaires: etude comparative des caractéristiques des suicidants a répétition et des primosuicidants i admis aux urgences d'un hôpital général Tunisien.

UNLABELLED: Repeat suicide attempts constitute a special problem in suicidology. It seems that the excess mortality by suicide is even higher among the suicide repeaters. The objectives of this study were to estimate repeat suicide attempts frequency among a sample of suicide attempters admitted in the University Hospital Emergency of Monastir (Tunisia), to compare their features to those of first-time attempters and to determine factors associated with repeat suicide. METHOD: A transversal survey involves a review of all patients committing suicide attempt and who are admitted in the emergency service during the second semester of 1999. Study variables included: demographic parameters, family and personal psychiatric history, axis I psychiatric disorder and circumstances of the present suicide attempt. Also, subjects were evaluated with the following scales: Montgomery and Asberg Depression Rating Scale (MADRS) and The Social Readjustment Rating Scale of Holms and Rahe. RESULT: Among the 90 suicide attempters, 42.2% (n = 38) had made at least one previous suicide attempt. More repeaters than first-time attempters were divorced or separated: 21.1% versus 5.8% (p = 0.05). Belonging to a numerous family (n > or = 4) was more frequent in the repeaters group: 73.7% versus 46.2% (p = 0.01). The two groups did not differ as to level of education but were significantly different with regard to their professional activity: 60.5% of repeaters were unemployed versus 34.6% of first-time attempters (p = 0.01). Repeaters had more loaded family psychiatric disorders: 26.3% versus 7.7% (p = 0.03). However there were practically no differences between repeaters and first-time attempters in regard of suicide in their families. Personal previous history of repeaters was characterized by frequency of psychiatric hospitalization: 50% versus 11.5% (p = 0.00005). Sexual abuse was more frequent in repeaters group but this difference was not significant. Alcohol and drug abuse were not frequent in the two groups. Concerning the actual suicide attempt, the most frequently diagnosed disorder was adjustment disorders. However depressive and psychotic disorders were significantly more frequent in the repeaters group: 34.2% versus 13.4% (p = 0.05). Repeaters had more frequently elevated scores (> 14) in MADRS: 71.1% versus 48.1% (p = 0.01), and raised intensity of stress factors lived during the six months preceding actual suicide attempt: 68.4% versus 42.3% (p = 0.04). Nevertheless we hadn't noticed any differences between the two groups regarding the methods used or the motives. CONCLUSION: Differences in the characteristics of repeaters and first-time attempters are therefore of interest when discussing future suicidal risk and should clear on preventive actions in order to face the increase of suicidal recidivism. A broad based, multidisciplinary intervention approach is recommended.

[Diagnostic strategy and management of anemia: a consensus from a detailed study of 100 patients followed in internal medicine]. / Strategie diagnostique et conduite pratique devant une anemie: d'apres une etude approfon- die de 100 patients suivis en medecine interne.

Anemia is a frequent reason for seeking medical care in Internal Medicine. It is not a diagnosis, but rather a symptom that needs to be investigated in order to find an etiology. In a retrospective review of 100 cases of anemia, the cause was found in 86 % of cases. The etiologic profile was varied. Iron deficiency remained by far the most frequent cause seen in 47% of case. Other etiologies have been found such as neoplasm in 13 % of cases, chronic renal failure in 8% of cases and endocrinal cause in 5 % of cases. We recommend a diagnostic decision tree that provides a tool for rational and cost effective approach for anemia.

[Acute leukemia in the elderly patient. Forty case reports]. / Leucémies aiguës du sujet âgé. A propos de 40 cas.

Between 1989 and 1996, 40 cases with acute leukemia (16 males and 24 females) were diagnosed in our institution. Median age was 65 years (range, 56-88 years). Leukocyte count was more than 30.109/l in 42% of cases. According to the French-American-British (FAB) criteria, 11 cases were classified lymphoblastic and 29 myeloblastic. Sixteen patients have received palliative treatment because of there age and there bad performance status. Only 24 patients have received curative treatment. Complete remission was achieved in 12 cases (50%), 5 cases (20%) failed to respond and 7 (30%) died during induction. Relapse was observed in 8 cases. The 2-year survival rate was 10% confirming the worse prognosis of the acute leukemia in elderly.
