Schistosomiasis and the risk of bladder cancer in Alexandria, Egypt

The relationship between history of schistosomiasis and bladder cancer risk was investigated using data from a case-control study conducted between January 1994 and July 1996 in Alexandria, Egypt. Cases were 190 subjects with incident, histologically confirmed invasive cancer of the bladder, and controls were 187 subjects admitted to hospital for acute, non-neoplastic, non-urinary tract conditions. Eighty-six cases (45%) vs 69 controls (37%) reported a history of urinary schistosomiasis. The corresponding multivariate odds ratio (OR) of bladder cancer -- after allowance for age, sex, education, smoking, other urinary infections and high-risk occupations -- was 1.72 (95% confidence interval (CI) 1.0-2.9). The ORs were 0.22 (95% CI 0.1-0.4) for intestinal schistosomiasis and 0.32 (95% CI 0.1-1.9) for schistosomiasis of other types. The OR for urinary schistosomiasis was higher in subjects who were younger at first diagnosis (OR of 3.3 for <15 years) and in those with a long time since first diagnosis (OR of 3.0 for > or = 35 years). The ORs were 15.8 for male ever-smokers with a history of urinary schistosomiasis, compared with never-smokers without such a history, and 3.2 for men ever-infected with urinary Schistosoma haematobium and ever-employed in high-risk occupations, compared with those never-infected and with no high-risk occupational history. This study confirms that clinical history of urinary schistosomiasis is significantly, but modestly, associated with increased bladder cancer risk, explaining some 16% of bladder cancer cases in this Egyptian population.

Epidemiology of bladder cancer in Alexandria, Egypt : Tobacco smoking

The relationship between smoking and bladder cancer risk was investigated using data from a case‐control study conducted between January 1994 and July 1996 in Alexandria, Egypt. Cases were 151 males with incident, histologically confirmed invasive cancer of the bladder, and controls were 157 males admitted to hospital for acute, non‐neoplastic, non‐urinary tract, non‐smoking‐related conditions. With reference to never smokers, ex‐smokers had a multivariate odds ratio (OR) of 4.4 [95% confidence interval (CI) 1.7–11.7] and current smokers of 6.6 (95% CI 3.1–13.9). The ORs were 5.4 for <20 and 7.6 for ≥20 cigarettes per day. After adjustment for cigarette smoking, the ORs were 0.8 for waterpipe and 0.4 for hashish smokers. The risk was significantly related to duration of smoking (OR of 16.5 for >40 years), and inversely related to age at starting (OR of 8.8 for starting <20 years), and inversely related to time since quitting smoking. Compared with never smokers who did not report a clinical history of schistosomiasis, the OR was 9.4 for smokers with a history of schistosomiasis, and 10.7 for smokers ever employed in high‐risk occupations compared with non‐smokers not reporting such a history. Thus, our results, while not giving indications of an increased bladder cancer risk with habits other than cigarette smoking, found a remarkably strong association with various measures of cigarette smoking that could explain 75% of bladder cancer cases among males from Alexandria. The prevalence of smoking was very low among women, and consequently tobacco was not a relevant risk factor for female bladder cancer. Int. J. Cancer 73:64–67, 1997.

Health care for diabetic patients in developing countries: a case from Egypt.

The aim of this was to evaluate the pattern of care for diabetic patients in Alexandria as a model from a developing country. It is a cross-sectional multi-centric. One thousand diabetic patients who had diabetes for no less than one year were randomly selected from 14 out-patient clinics and diabetic centres. Results showed that monitoring of the glycaemic state was based, almost entirely upon fasting blood glucose levels, with only a small minority (4%) having HbA measurements. During the previous 12 months, an electrocardiogram had not been performed in 26% of the subjects studies and the fundus was not examined in 38%. Twenty nine percent did not receive neurological examination, and feet were not inspected in 24%. Testing for albuminuria, serum creatinine, blood cholesterol, and triglycerides was performed only in 34%, 37%, 36% and 32% respectively. Patients habits in seeking care revealed that 78% regularly attended the medical centre for follow up, 64% followed dietetic instructions, and 89% were compliant with prescribed therapy. Only 8% did self examination of blood glucose and 26% checked glucose in urine by themselves. Generally, the pattern of care provided for health insured diabetic patients is better than that received by non-health-insured cases. It is concluded that in Egypt the quality of diabetes care differs in many aspects from the recommended standards and that structural as well as organisational improvements are urgently needed, particularly to guarantee adequate care to non-health insured patients.

Quality of Care of Children With Chronic Diseases in Alexandria, Egypt: The Models of Asthma, Type I Diabetes, Epilepsy, and Rheumatic Heart Disease

Objectives. To evaluate the quality of care delivered to children suffering from index chronic diseases using specific indicators of health care delivery and to study the predictors of suboptimal quality of care (SQC) and its outcome on children. Design. Over a 9-month period, guidelines for optimal care were formulated. A specific questionnaire for every studied chronic disease was prepared in collaboration with the clinicians in charge of the diseased children (66% pediatricians and pediatric specialists and 34% adult specialists). The clinicians were asked to write the details of daily practice, ie, how these children were managed on a routine basis as well as in an emergency situation. A cross-sectional study was conducted over a 4-month period and included 953 children suffering from bronchial asthma (BA), childhood epilepsy (CE), type I diabetes mellitus (IDDM), and rheumatic heart disease (RHD). A systematic random sample of children was selected from children visiting the ambulatory settings of all childrens hospitals. Every fourth child was selected on 2 randomly chosen days each week, while all diseased children admitted in the hospital settings of the childrens hospitals during the study were included. A general form describing the impact of the diseases on the child was prepared. A network of clinicians was created in all childrens hospitals; seminars were held during which the content validity of the questionnaire was tested. Items were evaluated for their internal consistency using the Cronbach α. According to the degree of adherence to the recent therapeutic guidelines concerning selected indicators of the quality of care specific to every disease, children were categorized as receiving optimal quality of care or SQC. These indicators were: the use of inhaled bronchodilators in acute asthmatic attacks in mild asthma and the use of the prophylactic drugs (inhaled sodium cromoglycate or inhaled beclomethasone) in moderate to severe chronic BA in between acute asthmatic attacks; compliance with antiepileptic drugs in epileptic children; regular performance of self-monitoring of blood glucose and/or urine testing in diabetic children; and compliance with prophylactic antibiotics in children suffering from RHD. The records of the outpatient clinics for ambulatory and hospitalized cases were reviewed to assess the degree of compliance with the prescribed management before the index visit. Sociodemographic characteristics and health care system-related predictors of SQC were analyzed via stepwise logistic regression analysis. The impact of illness on the child was assessed by 7 items which were: dependence on parents in domestic activities, level of activity compared with peers, mood compared with peers, level of socializing, degree of discomfort attributable to illness, level of physical disadvantage, and urinary incontinence. Factor analysis with Varimax rotation was performed on items related to the impact of illness. Parental satisfaction with care was rated as excellent, very good, fair, or poor. Information on school outcome was obtained by asking the caretakers whether the child was able to attend school regularly despite his sickness. Scholastic achievement was also rated as excellent, very good, good, and acceptable. Parents were asked whether the child had ever repeated a grade because of his sickness. Setting. Ambulatory and hospital settings of all childrens hospitals in Alexandria, Egypt. Results. Only 52% of mild asthmatics were given inhaled bronchodilators during acute attacks and 6.84% of moderate to severe asthmatics were taking prophylactic drugs (inhaled sodium cromoglycate and/or inhaled beclomethasone) between acute attacks. Similarly, only 53 of 134 (39.6%) of diabetic children were regularly performing self-monitoring of blood glucose and/or urine testing. In contrast, in epileptic children, 121 of 173 (69.9%) were judged as being compliant by their managing clinicians and more than two thirds 82/123 (66.7%) of children with RHD were compliant with the secondary prophylactic antibiotic. Predictors of SQC were younger age of the child (in BA and CE), lower maternal education (in BA and IDDM), charged medication (in BA, IDDM, and RHD), suburban residence (in moderate to severe BA), lower paternal education (in CE), and management in health facilities other than university hospital (in IDDM). Regarding the outcome of chronic diseases on children, factor analysis revealed 2 factors (physical and psychosocial impact) that explained 41.5% of variance with moderate adequacy (Kaiser-Meyer-Olkin test of sampling adequacy = .67). Dependence on parents in domestic activities, urinary incontinence, physical disadvantage, and the degree of discomfort attributable to illness were all aggregated into the physical impact factor, whereas the level of socializing, mood, and the level of activity compared with peers were aggregated into the psychosocial impact factor. There was a strong association between the severity of psychosocial impact and the quality of delivered care in CE and RHD, as well as between the parental satisfaction with care and the quality of delivered care for the 4 index diseases. However, there was no significant association between the severity of physical impact or school performance parameters and the quality of delivered care (apart from grade repeating in RHD). Conclusions. With respect to the declared primary goal of the study, the most interesting findings could be summarized as follows: Cultural and economic factors are the primary predictors of SQC for childhood chronic diseases. Noncompliance to medication reflects the quality of delivered care in terms of defective health education rather than problems in the availability of medications in the local market as in many other developing countries or problems in the access to pharmacy or health services. Parental satisfaction with care seems to be a reliable marker of the quality of health care delivery regardless of the educational level of the community. Therefore, it could be used as a sensitive marker for the quality of health care even in developing countries. Chronic diseases have a profound impact on children, especially those belonging to the lower socioeconomic levels of the society, their scholastic performance, and the health care system. Regular monitoring of the health system performance is warranted, along with emphasis on health education programs for caretakers of children with chronic diseases. quality of care, chronic diseases, outcome.
