The purpose of this review is to address the global incidence and management of snakebite envenomation and to describe the clinical characteristics and pathogenesis of envenomation by species of the family Viperidae, genera Bothrops and Crotalus, the most common venomous snakes in Brazil. We focus on the pathogenesis of the acute renal failure induced by these snakes. ⋯ In developed nations, snake bite typically occurs during recreational activities, whereas in developing countries it is an occupational disease more likely to affect young agricultural workers, predominantly men. Scarcity and delay of administration of antivenom, poor health services, and difficulties with transportation from rural areas to health centers are major factors that contribute to the high case-fatality ratio of snakebite envenomation.

There are well-known Black-White disparities in adverse birth outcomes, health behaviors, and chronic diseases such as asthma, diabetes, and hypertension. These disparities hold across socioeconomic status and have remained stable for the past 50 years despite efforts to reduce them. ⋯ We review evidence that Black neighborhoods have significantly poorer healthcare facilities staffed by less competent physicians, higher environmental exposures, and poorer built environments than do White neighborhoods, and we argue that these neighborhood disparities are 3 pathways through which segregation contributes to health disparities. We summarize the research needed on the role of segregation in health disparities and emphasize the hypothesis that these may be differences between Whites and segregated Blacks alone.

The already inadequate health systems of Africa, especially sub-Saharan Africa, have been badly damaged by the migration of their health professionals. There are 57 countries with a critical shortage of healthcare workers, a deficit of 2.4 million doctors and nurses. Africa has 2.3 healthcare workers per 1000 population, compared with the Americas, which have 24.8 healthcare workers per 1000 population. ⋯ There is a need for concerted political will and funding support that will allow them to do what is necessary. It may well be asked why special measures should be necessary to influence the migration of health professionals rather than engineers or football players or any other category. The answer must surely be that no other category of worker is so essential to the well-being of the population of every nation.

Chronic kidney disease is at least 3-4 times more frequent in Africa than in developed countries. Hypertension affects approximately 25% of the adult population and is the cause of chronic kidney failure in 21% of patients on renal replacement therapy in the South African Registry. The prevalence of diabetic nephropathy is estimated to be 14%-16% in South Africa, 23.8% in Zambia, 12.4% in Egypt, 9% in Sudan, and 6.1% in Ethiopia. ⋯ The transplant rate in Africa averages 4 pmp and is 9.2 pmp in South Africa. The goal for sub-Saharan Africa should be to have a circumscribed chronic dialysis program, with as short a time on dialysis as possible, and to increase the availability of transplantation (both living related and cadaver) and promotion of prevention strategies at all levels of health care. Screening for kidney disease in high-risk populations, eg, patients with hypertension and diabetes mellitus and a family history of kidney disease, should be instituted as the first step in kidney disease prevention in developing countries.

Comparative Study
Racial/ethnic differences in bystander CPR in Los Angeles, California.
Bystander CPR (BCPR) has been demonstrated to improve rates of return of spontaneous circulation, survival to hospital admission, and quality of life in survivors. While previous studies have shown that African Americans are less likely to receive BCPR than Caucasians even after adjusting for variables such as socioeconomic status, BCPR rates in Latinos have not been reported. ⋯ After adjusting for other variables, Latinos in Los Angeles receive bystander CPR at approximately half the rate of Caucasians.
