ABSTRACT
BACKGROUND: Access to high quality medical care and especially to complex procedures may be adversely affected in members of a minority ethnic group or a lower socioeconomic class. For example, Caucasians undergo coronary artery bypass grafting (CABG) or percutaneous transluminal coronary interventions (PTCI) twice as frequently as African-Americans. Data exist to suggest that African-Americans derive less benefit than Caucasians from CABG. HYPOTHESIS: We investigated the possibility that outcomes of catheter-based coronary angioplasty might also be less favorable in minority populations. METHODS: We analyzed in-hospital outcomes in 6,559 consecutive patients who underwent PTCI in our laboratory. In 37 ethnicity was classified as "other," 5,203 (79.8%) were identified as Caucasians, 863 (13.2%), as African-Americans, and 456 (7.0%), as Hispanics. Twelve baseline clinical, angiographic, and procedural characteristics were entered into a computerized data base. Hospital complications were identified by trained quality assurance nurses. RESULTS: Substantial differences in baseline characteristics existed between the populations. Despite these differences, on univariate comparison of ethnicity and outcome, no differences between ethnic groups were found with a single exception. Mortality in Hispanics was higher than in the other two populations. (2.0 vs. 0.7 and 0.8%, respectively, p = 0.008). However, when this was adjusted for baseline characteristics, the difference was not significant. CONCLUSIONS: In contrast to previous studies suggesting less favorable outcomes of CABG in African-American patients, this analysis demonstrates an equal frequency of procedural success and rate of hospital complications for PTCI in that population, in Hispanics, and in Caucasians.

Injuries result in major financial and productivity losses to nations while inflicting tremendous personal burden on the injured and their families. Two-thirds of the global deaths from injuries occur in the developing world, consuming substantial health sector resources. Pakistan is a developing country with a population of 136 million and no reported estimate of the national impact of injuries. This study presents a profile of injuries in Pakistan, estimates the impact on the country and recommends strategies to further delineate this important public health problem. A methodical review of published, unpublished and government literature was undertaken and data collected for all types of injuries principally over the 1982-1994 period. Motor vehicle injuries, homicides, assaults, work-related injuries, poisonings and risk factors have been included. Selected epidemiological estimates have been generated and the WHO motorization index has been used to assess road-side accident risk. The lack of reliable data and under-reporting of work-related injuries is revealing. The rising time trend in all injuries, the significant loss of life from injuries and the age of those injured have a critical impact on the national economy and health system. Data on injuries in Pakistan are primarily recorded by police authorities and used for legal purposes. Pakistan must institute an information system to evaluate the true impact of injuries and develop national safety standards. Implementation of such standards is especially important for road traffic safety and occupational health in industrial units within the country.

This retrospective case--control study analyses the prevalence and outcome of macrosomia in a part of the underdeveloped world. Out of 6,093 deliveries at a large tertiary care centre, 234 (3.8%) were macrosomic. Maternal risk factors associated with the condition included age over 35, obesity, grand multiparity, postmaturity and impaired glucose tolerance. Operative deliveries were more common as was shoulder dystocia, birth trauma, fetal distress, the need for neonatal intensive care and perinatal loss.
