Fenfluramine is a recently introduced anorexigenic drug for the treatment of obesity. 5 cases of hypertension induced or aggravated by fenfluramine are described. They include 4 females and one male seen and followed in the Hypertension Clinic of the Lagos University Teaching Hospital. Even though there was loss of weight while they were on fenfluramine there was a rise in blood pressure in 4 of them despite concurrent therapy with antihypertensive agents. In one female patient the rise in blood pressure occurred while on self-medication with the drug alone. In all of them the blood pressure fell when fenfluramine was stopped. Although there have been many reports of the effectiveness in the treatment of obesity, reports of its adverse reactions have been few and there has been no mention of hypertension. The drug brochure warns that hypotension may even occur. In view of the present case reports it is advisable that those who are on fenfluramine should have their blood pressure checked regularly particularly if they are also known to be hypertensive.

It is recognized that postoperative mortality, infarction and the need for inotropic support are increased following myocardial revascularization in highrisk patients. Operations were carried out in 57 such patients in whom one or more of the following factors were present: ventricular dysfunction-ejection fraction less than 0.4 (17), unstable (8) or preinfarction angina (29), evolving infarction (8), recent infarction (less than two weeks before) (5) and refractory ventricular tachyarrhythmia (4). Combined risk factors were present in nine patients. The following principles were utilized to minimize ischemic injury: (1) avoidance of prebypass hypertension and hypotension, (2) avoidance of extreme hemodilution, (3) avoidance of ventricular fibrillation, (4) maintenance of beating empty heart, when possible, (5) the limiting of ischemic periods to less than 12 minutes (hypothermia 32 degrees C) and (6) repaying myocardial oxygen debt with total (vented) bypass, when necessary. The following results were obtained: inotropic support was required in five patients (9 percent), "new" postoperative infarction occurred in five patients (9 percent) and one patient died (2 percent). These results are comparable to those reported in good-risk patients, and indicate that optimal myocardial protection will allow safe revascularization in a high-risk patient.

In order to evaluate the level of maternal mortality at Conakry, capital of Guinea (West Africa), a descriptive epidemiological study was made of all maternal deaths occurring between July 1st, 1989 and June 30th, 1990. To ensure that cases of maternal death were recorded as exhaustively as possible, we conducted this study over 1 year in municipal and hospital maternity units, and 3 months in the urban community. One hundred thirty-nine maternal deaths were registered, representing an annual maternal mortality rate of 559/100,000 live births. The main causes of maternal death were abortion, complications linked with hypertension, and postpartum bleeding.

Marked ethnic differences in hypertension prevalence have been described in Jewish immigrants to Israel. The extent to which this phenomenon has persisted after a long period of living in the same country, and whether native-born descendants exhibit similar patterns, is not clear. The aim of this study was to determine the prevalence of hypertension in immigrants to Israel and native-born Israelis by region of origin and age at immigration. Complete data were available for 5,146 subjects (3,607 men and 1,539 women) aged 20-64 years who were employed in Israeli industries and were examined during 1985-1987. In both sexes, Jews originating in the West (Europe and the Americas) had higher blood pressures and a significantly higher prevalence of hypertension than those from northern Africa or Asia, particularly in the age group 20-44 years (17% vs. 9% and 8% in men, respectively, and 9% vs. 3% and 5% in women). There was a significant positive association between the prevalence of hypertension and age at immigration (p less than 0.001) in both sexes, and this finding was present in all ethnic groups. In multiple logistic regression analysis, the associations of hypertension with ethnic origin and age at immigration were only partly explained by variations in body mass index, after controlling for other potentially confounding variables. These findings suggest that despite these subjects' having shared a relatively similar physical environment for many years, ethnic differences in the prevalence of hypertension persist. Immigration at an older age was associated with a higher prevalence of hypertension for both subjects originating in industrialized countries and those originating in nonindustrialized countries, suggesting that the process of immigration itself may adversely affect blood pressure.

Gypsies in the United States are not a healthy group. They have a high incidence of heart disease, diabetes mellitus, and hypertension. When they seek medical care, Gypsies often come into conflict with medical personnel who find their behavior confusing, demanding, and chaotic. For their part, Gypsies are often suspicious of non-Gypsy people and institutions, viewing them as a source of disease and uncleanliness. Gypsy ideas about health and illness are closely related to notions of good and bad fortune, purity and impurity, and inclusion and exclusion from the group. These basic concepts affect everyday life, including the way Gypsies deal with eating and washing, physicians and hospitals, the diagnosis of illness, shopping around for cures, and coping with birth and death.

The incidence of retinal vein occlusion (RVO) is known to be related to several cardiovascular risk factors including diabetes mellitus, hypertension and hyperlipidaemia. We have assessed the prevalence of these risk factors in Caucasian (N = 536, mean age = 65.21 years), West Indians (N = 24, mean age = 57.3 years) and Asian (N = 28, mean age = 51.4 years) patients presenting with RVO. We found no significant differences between the three groups in the distribution of hyperlipidaemia, but diabetes mellitus was more common amongst both the Asians and W. Indians (10% v 29% and 38%, p < 0.01 and p < 0.001). Hypertension was also more common in both the Asians and the West Indians (59% v 64% and 83% m p < 0.001 and p < 0.0001). The Asians and West Indians presenting with RVO were significantly younger and had significantly higher body mass index than their Caucasian counterparts (Ethnic origin, BMI, mean age: Asian, 28.1 +/- 4.3, 51.5 +/- 12.3 years; West indian: 30.2 +/- 7.7, 57.3 + 10 years; White: 24.8 +/- 4.2, 65.2 +/- 11.4 years). In this study RVO occurred at a younger age in Asians and West Indians, and was associated with a greater prevalence of diabetes mellitus and hypertension. The prevalence of hyperlipidaemia was no different in the three groups.

The prevalence of hypertension and the relationship between blood pressure, age, body mass index (BMI) and urinary cations from casual urine specimens were examined in 1,513 Chinese employees of a public utility company and non-medical personnel of a district hospital. The prevalence of hypertension, defined as systolic blood pressure greater than or equal to 140 or a diastolic blood pressure greater than or equal to 90 mmHg, or a past history of hypertension, was 17% in men and 5% in women. After excluding subjects who were on antihypertensive medication, age, body mass index, and urinary sodium/potassium ratio were independently and positively associated with blood pressure, while urinary potassium/creatinine ratio was inversely related to blood pressure. No association with urinary sodium or sodium/creatinine ratio was found. Higher mean blood pressure in men was accompanied by lower urinary potassium/creatinine and potassium concentration and higher sodium/potassium ratio, even though men had the same mean BMI when compared with women. A difference in potassium intake between the sexes may partly account for this finding. We conclude that in this Chinese population, whose dietary intake is more influenced by the West compared with Chinese in the Peoples' Republic of China, age and BMI are important determinants of blood pressure, together with potassium intake as reflected by urinary potassium excretion. No association of blood pressure with sodium excretion was demonstrated.

Social class related differences in prevalence of cardiovascular disease risk factors in Germany were investigated with special emphasis on comparisons between East and West Germany and on time trends. Databases for West Germany are the first and second National Health Survey (survey 1: N = 4794, survey 2: N = 5315), carried out in the framework of the German Cardiovascular Prevention Study, and for East Germany the first GDR-MONICA project (N = 6125). Different social class indices were applied to evaluate social inequities for hypertension, hypercholesterolemia, cigarette smoking, obesity and predicted cardiovascular disease mortality. As a main result, it was found that very similar patterns in the relation between social class characteristics and cardiovascular disease risk factor prevalence occurred for both parts of Germany. Social class gradients were strongest for obesity and weakest for hypercholesterolemia. Analysis of time trends for the period from 1984 to 1988 (for West Germany only) revealed an increase in social inequalities for hypertension in males and cigarette smoking in females. These findings point to the need to focus more on social disadvantaged segments in the population when community based health promotion and disease prevention programs are brought into action.

Urinary tract infection is a common and frequently recurring condition in children. The susceptibility of the host, the presence of urinary tract abnormalities, and the virulence of the urinary pathogens are of primary importance in the development of the infection. Renal parenchymal scarring, hypertension, and renal insufficiency are well-established complications of the infection in children. To reduce the risk of renal damage, diagnosis and treatment must be prompt. The diagnosis demands radiologic evaluation of the urinary tract in all boys, all children younger than 5 years, all patients with voiding dysfunction, and school-aged girls with recurrent infection to identify those patients with vesicoureteral reflux, obstruction, or other urinary tract abnormalities. Both voiding cystourethrography and renal ultrasonography are the initial examinations to use to determine the next appropriate study. Children with vesicoureteral reflux or with recurrent urinary tract infections should receive prophylactic antibiotic therapy and should be observed closely to prevent renal scarring.

The slavery hypothesis for hypertension has stated that the high blood pressures sometimes measured in African Americans are caused by one or more of these conditions: first, salt deficiency in the parts of Africa that supplied slaves for the Americas; second, the trauma of the slave trade itself; third, conditions of slavery in the United States. A review of the historical evidence shows that there was no salt deficiency in those parts of Africa, nor do present-day West Africans have a high incidence of hypertension. Historical evidence does not support the hypothesis that deaths aboard slave ships were caused mainly by conditions that might be conductive to hypertension, such as salt-depleting diseases. Finally, the hypothesis has depended heavily on evidence from the West Indies, which is not relevant for the United States. There is no evidence that diet or the resulting patterns of disease and demography among slaves in the American South were significantly different from those of other poor southerners.
