Haemophilia in the developing world: successes,frustrations and opportunities

Summary. There is a need to bridge key gaps between high‐ and low‐income countries and individuals; between health policy and clinical practice; and between producers and users of healthcare technology and scientific evidence. The objective of this report was to perform a diagnosis of the situation in the developing world through a survey. This survey was conducted to gather specific information on various aspects related to haemophilia. Countries were chosen by their comparability in infant and adult mortality rates according to the regionalization proposed by the World Health Organization. These indicators are very sensitive to socioeconomic conditions, and have been widely used to study health inequalities. All regions, except Africa and the East Mediterranean, were represented. Africa was excluded because its indicators were not comparable. The East Mediterranean was not represented because of difficulties in contacting investigators. Twenty‐one country representatives were contacted, and 11 answered the questionnaire. Successes obtained by developing countries are based more on the skills and creativity of the local professionals than on the availability of state‐of‐the‐art technology. Frustrations were related to disease underregistration and the limited availability of treatment products. Haemophilia care in the developing world is not as fair as we would like it to be. Governments do not always cover treatment costs, and a very small percentage of the national health budgets is alotted to haemophilia care. The role of the World Federation of Hemophilia was considered crucial by all the investigators surveyed. Training programmes and supply of factor concentrates were the main contributions identified by the respondents.     

广西武鸣华侨农场心血管病危险因素的调查研究

对广西武鸣华侨农场4158人进行基线普查,410人进行膳食调查和作8小时夜尿电解质测定,并将高血压低发区广西的资料与高发区的北京作对比.结果显示,体重指数高是高血压一个重要的危险因素,而体重过重又与膳食中摄入碳水化合物和总热量大有关.另一主要的危险因素是钠,膳食中摄入钠高,尿Na和Na/K比值高者,血压水平和高血压的患病率亦高.

The practice of breast self-examination results in the earlier detection and better clinical course of Japanese women with breast cancer

Using a questionnaire survey, we analyzed the relationship between the frequency of breast self-examination (BSE) and the clinical stage and course of breast cancer in Japanese patients. BSE had been performed monthly by only 5.4% of the patients (M group), occasionally by 35.4% (O group), and not at all by 59.2% (N group). There was a positive relationship between more frequent BSE and an earlier clinical stage, the percentages of Tis/stage 0 and I for the M, O, and N groups being 83%, 44%, and 36%, respectively (P<0.05). The mean maximum tumor diameters for the three groups were 1.7cm, 2.5cm, and 3.0cm, respectively. The tumor size in the M and O groups was significantly smaller than that in the N group atP<0.01 andP<0.05, respectively. The percentages of patients in the M, O, and N groups who underwent breast-conserving therapy were 42%, 11%, and 19%, respectively, with patients who had performed monthly, BSE more frequently undergoing breast-conserving therapy (P<0.05). At a median follow-up time of 34 months, 0%, 3.8%, and 7.6% of the patients from the M, O, and N groups, respectively, had died of breast cancer, the overall survival curve of the M group being significantly better than that of the N group (P<0.01). This retrospective study suggests the positive correlation of BSE frequency with earlier detection, and a more favorable clinical course in Japanese breast cancer patients.     

Risk factors of type 2 diabetes among Korean adults: The 2001 Korean national health and nutrition examination survey

This study aimed to identify risk factors for type 2 diabetes (T2D) in Korea, a rapidly changing country. Data of 5,132 adults aged 20-85 were used from the 2001 Korean Health and Nutrition Examination Survey. Multiple logistic regression was carried out to identify risk factors for T2D. Three models were specified: (i) socioeconomic and demographic factors (model 1: age, gender, education, poverty income ratio, employment), (ii) behavioral risk factors and covariates (model 2: obesity, physical activity, smoking, alcohol drinking, dietary quality, family history of T2D, co-morbidity) and (iii) socioeconomic, demographic, and behavioral factors (model 3). The prevalence of T2D was 7.4%. Less education (OR 1.41, 95% CI 1.08-1.84), age (OR 2.19, 95% CI 1.56-3.08 in 40-59 yrs, OR 4.05, 95% CI 2.76-5.95 in 60 yrs + comparing to 20-39 yrs) and abdominal obesity (OR 2.24, 95% CI 1.79-2.82) were risk factors for T2D even after controlling for other factors simultaneously. There was a significant association of T2D with ever smoking (OR 1.34, 95% CI 1.06-1.67). The relationship of age with T2D was modified by gender in model 1 and the relationship of smoking with T2D was modified by obesity in model 2. Less educated, older, obese or ever smokers were more likely to have T2D. Gender mediated the relationship of age, and obesity mediated the relationship of smoking, with T2D. Intervention programs for T2D in Korea should take the interactions among risk factors into account.     

Practice of orthokeratology by a group of contact lens practitioners in Hong Kong

Purpose: The aim of the study was to provide information about the characteristics of three main types of orthokeratology (ortho‐k) lenses used in Hong Kong and to report on their performance based on the clinical impressions of a group of ortho‐k practitioners. Method: Twelve ortho‐k practitioners were interviewed between 1 March and 30 June 2001. Results: Most ortho‐k lenses were ordered from three manufacturers: DreimLens, Fargo and Contex. The median maximum myopia reduction reported for DreimLens, Contex and Fargo lenses were 6.25 D, 6.00 D and 4.50 D respectively. The time to reduce myopia by up to 4.00 D could be up to three weeks for Contex and DreimLens and up to four weeks for Fargo. For reduction of myopia by up to 4.00 D, the treatment usually required only one or two lenses per eye for all three types of lenses. The incidence of lens binding and lens tightening after achieving the optimal reduction was reported to be higher with the DreimLens design. Good centration, less lens binding, relatively lower incidence of complications and lens tightening after achieving the optimal reduction were reported with the Fargo lenses. Conclusions: DreimLens tended to be more effective for myopia reduction. However, some practitioners were concerned with the aggressiveness of myopia reduction using this lens design and the higher potential for ocular complications. Selection of the lens design is dependent on various factors, in particular, practitioners need to be comfortable with the design they choose and to consider the needs of their patients and the final goal of the treatment.

Nationwide investigations of intestinal obstruction in Japan

Two nationwide questionnaire surveys of intestinal obstruction in Japan were undertaken, covering two two-year periods, from January, 1975 to December, 1976 and from January, 1985 to December, 1986, respectively. The findings of a comparative review of these two surveys indicated that although the overall mortality of intestinal obstruction had not changed between 1975/76 and 1985/86, being 6.8 per cent and 6.5 per cent, respectively, simple adhesive obstruction had decreased from 3.2 per cent in 1975/76 to 2.0 per cent in 1985/86. The main cause of adhesion was laparotomy and in cases of both simple adhesive obstruction and strangulated adhesive obstruction, the rate of adhesion secondary to laparotomy of the upper gastrointestinal tract and colon and rectum had increased between 1975/76 and 1985/86. Obstructions caused by neoplasms had increased from 8.2 per cent in 1975/76 to 10.0 per cent in 1985/86, while those caused by adhesions had incresed further still, from 42.5 per cent in 1975/76 to 60.8 per cent in 1985/86. Among the latter group, nonoperatively treated cases had increased, which may be accounted for by the fact that facilities which adopt non-operative treatment using intestinal decompression as the first choice for simple adhesive obstruction cases have increased. In both surveys, the mortality of cases receiving nonoperative treatment was lower than that of operative cases.
