Objectives: To determine the age specific prevalence of impairment and disability relating to hemiplegic stroke in one rural area of Tanzania.Methods: During the yearly house to house census of the study population of 148 135 (85 152 aged 15 and over) in August 1994, specific questions were asked to identify those who might be disabled from stroke. People thus identified were subsequently interviewed and examined by one investigator. In those in whom the clinical diagnosis of stroke was confirmed a more detailed interview and examination relating to risk factors and recovery was carried out.Results: One hundred and eight patients, 61 men and 47 women, were identified with a median age of 70 (range 18-100). Median age at first stroke was 65 years. The age specific rates in this study were lower than previous studies in developed countries. All were cared for at home although 23 (21%) were bedbound.Conclusions: Although prevalence of impairment and disability related to stroke in this population as a whole was low this is mainly explained by the age structure, with less than 6% being aged 65 and over. Age standardised rates for stroke with residual disability were about half those found in previous studies in developed countries. Death from stroke in Africa may be higher but data are limited. With the demographic transition stroke is likely to become a more important cause of disability in sub-Saharan Africa. [ABSTRACT FROM AUTHOR]

Background: Most data for stroke mortality in sub-Saharan Africa are hospital based. We aimed to establish the contribution of cerebrovascular disease to all-cause mortality and cerebrovascular disease mortality rates in adults aged 15 years or more in one urban and two rural areas of Tanzania.Methods: Regular censuses of the three surveillance populations consisting of 307,820 people (125,932 aged below 15 years and 181,888 aged 15 or more) were undertaken with prospective monitoring of all deaths arising in these populations between June 1, 1992 and May 31, 1995. Verbal autopsies were completed with relatives or carers of the deceased to assess, when possible, the cause of death.Findings: During the 3-year observation period 11,975 deaths were recorded in the three surveillance areas, of which 7629 (64%) were in adults aged 15 years or more (4088 [54%] of these in men and 3541 [46%] in women). In the adults, 421 (5.5%) of the deaths were attributed to cerebrovascular disease, 225 (53%) of these in men and 196 (47%) in women. The yearly age-adjusted rates per 100,000 in the 15-64 year age group for the three project areas (urban, fairly prosperous rural, and poor rural, respectively) were 65 (95% CI 39-90), 44 (31-56), and 35 (22-48) for men, and 88 (48-128), 33 (22-43), and 27 (16-38) for women, as compared with the England and Wales (1993) rates of 10.8 (10.0-11.6) for men and 8.6 (7.9-9.3) for women.Interpretation: We postulate that the high rates in Tanzania were due to untreated hypertension. Our study assessed mortality over a single time period and therefore it is not possible to comment on trends with time. However, ageing of the population is likely to lead to a very large increase in mortality from stroke in the future. [ABSTRACT FROM AUTHOR]

The prevalence of diabetes mellitus and impaired glucose tolerance (IGT) was assessed by use of WHO diagnostic criteria in 6299 Africans aged 15 years and above living in six villages in Tanzania. 0.87% (1.1% male, 0.68% female) had diabetes and 7.8% (6.9% male, 7.7% female) had IGT. Prevalence rates were 1.1% and 8.4%, respectively, when age-adjusted to the USA population. Only 7 (13.5%) of the 53 individuals with diabetes had been known to have the disorder; 34 (74%) of the other 46 were symptom-free. Mean age was 54 (SD 20) for diabetic subjects and 37 (17) years for the whole population. Diabetes and IGT rates did not differ significantly between villages despite geographical, socioeconomic, and dietary differences. Diabetes rates increased modestly with age and body mass index (BMI). Fasting blood glucose (FBG) levels did not rise significantly with age but correlated positively with systolic blood pressure (BP) and negatively with haemoglobin concentration (Hb) and BMI. The 2 hour post-glucose load blood glucose values correlated positively with age, sex, and systolic BP and negatively with Hb. Diabetes is less prevalent in rural Africa than in developed countries, even when age has been corrected for. This difference is probably related to body weight, diet, and exercise.

A community-based survey was used to acisess the prevalence of risk factors for coronary heart disease (CHD) in rural Tanzanians. In all, 8581 subjects (3705 men, 4876 women) aged ≱15 years in eight villages in three regions in rural Tanzania reprssenting a range of socioeconomic deprivation were studied. The main outcome measures were serum cholesterol and triglyceride level, Mood pressure and prevalence of dyslipidaemia, hypertension, smoking, overweight, impaired glucose tolerance (IGT) and diabetes; as well as ECG changes. Mean serum cholesterol levels in men were 4.2, 3.4 and 3.7 mmo/l, and in women 4.4 3.6 and 3.9 mmol/l in Kilirnanjaro, Morogoro and Mara regions respectively. In Kilimanjaro region 17.4% of men and 19.0% of women had values above 5.2 mmol/l compared with only 5.0% and 6.7% in Morogoro region and 4.8% and 6.9% respectively in Mara region. Systolic and diastolic blood pressures increased with age in both men and women in all three regions with the most marked increase in Kilimanjaro region and the smallest rise in Mara region. Mean age-adjusted values were highest in Kilimanjaro region (124175 mm Hg, and 125/76 mm Hg in men and women respectively) and lowest in Mara region (120/70 mm Hg in men and 118/68 mm Hg in women). Hypertension was found in 6.6% of men and 7.5% of women in Kilimenjero region, 3.3% and 4.7% in Morogoro, and 2.6% and 3.4% in Mara region. Cigarette smoking was found in 42.6% of men in Kilimanjaro region, 28.2% of Morogoro region and 8.6% in Mara region. Less than 4% of women smoked in all three regions. Only 2.4–4.0% of men, and 7.9–10.5% of women were overweight or obase. ST,T and Q,QS changes on ECG were recorded in 7.8% and 2.7% of men, and 17.4% and 3.7% of women aged ≤40 years. Diabetes was found in 0.6–0.8% as previously reported. The proportion of men with two or more risk factors for CHD ranged from 0.2% in Mara region to 4.6% in Kilimanjaro region. For women the corresponding figures ranged from 0% in Mara region to 1.1 % in Morogoro region. The proportion was incread in those with IGT (9.3%) and diabetes (14.1%). Similarly those with ischaemic (Q,QS) changes on ECG had a twofold increase in risk factors. Cardiovascular risk factor levels make it unlikely that CHD will emerge as a significant health problem among rural Tanzanians in the near future. [ABSTRACT FROM PUBLISHER]

A strategy of live related donor kidney transplantation coupled to the briefest possible preparatory period of haemodialysis was adopted as the most cost effective treatment for a selected group of 9 Tanzanian patients who received a total of 10 grafts. Patient and donor selection and preparation were carried out at Muhimbuli Medical Centre, Dar es Salaam, and the transplant procedure and first few months of follow-up were done at St. Thomas' Hospital, London. There was a high incidence of complications which drew attention to particular risk factors in the group treated. The high cost of treating these individuals emphasizes the need for research into chronic communicable and non-communicable diseases in Africa and highlights the dilemma of appropriate use of resources in serving the world's medical needs.

The prevalence of abnormal serum total thyroxine (T4) and triiodothyronine (T3) concentrations were determined in 1,206 in-patients in two associated psychiatric hospitals. The biochemical pattern of primary hypothyroidism occurred in five females and one male (prevalence 0.5 per cent), but in only one patient was the diagnosis clinically obvious. Eight patients (all female) were clinically hyperthyroid (prevalence 0.7 per cent), of whom six were previously undiagnosed. There was no evidence that phenothiazines or benzodiazepine therapy had any significant effect on thyroid hormone levels. The small differences in thyroid hormone levels between psychiatric diagnostic groups could be explained by differences in age distribution. [ABSTRACT FROM AUTHOR]

This article presents a study on pituitary function in Down's syndrome. In this study, eight male patients and eight female patients with Down's syndrome were selected on the basis of their having had a serum-thyroxine level of 61 n mol/l or below and a Thyroid Stimulating Hormone TSH level of 8 m U/1 or below. Permission to carry out pituitary function tests was obtained from the Lennox Castle Hospital Ethical Committee and written permission was obtained from the next of kin of the patients after full explanation of the procedures involved.
