Alcohol is a sedative/hypnotic with effects similar to those of barbiturates.1 The type of alcoholic beverages consumed depends on the social context and financial capability. Alcoholic beverages may be in form of beer, wine, dry gin. Drinking alcohol is an activity that many people enjoy; taking a few drinks occasionally is generally harmless. Most people do not have problems as a result of drinking alcohol in this manner, although this may predispose to heavy use. Heavy alcohol consumption has been shown in observational studies to have a strong positive association with elevated blood pressure.2-4 Further evidence have been shown by clinical trials5,6 that have demonstrated that reduction in alcohol intake among individuals who drink heavily (i.e. three or more drinks per day) can lower blood pressure in normotensive and hypertensive men. Some studies have recorded a linear dose-response relationship sometimes starting with a consumption threshold of three drinks per day (30 g of ethanol).7-13 In others, the relationship has been non-linear especially in women, and some authors have speculated that ingestion of small quantities may reduce blood pressure.14-22 These discrepancies may reflect differences in investigational design, methods and populations.23 Many studies have been done in this area in developed countries like the United States, United Kingdom and Australia. This is however, not a commonly researched area in this part of the world. The aim of this study was to assess the relationship between alcohol consumption and blood pressure of drivers of commercial vehicles.

Depression is one of the leading causes of mortality and morbidity worldwide. In the year 2000 depression accounted for 4.4% of the global disability adjusted life years (DALYs). The Kingdom of Saudi Arabia (KSA) has a population of 28 million people and is one of the countries experiencing demographic transition in its population structure. Improvements in socioeconomic status have been shown to be associated with increased chronic diseases including chronic mental diseases like depression, but still there is no comprehensive review summarizing the various reports currently existing in the literature. Although individual studies within Saudi Arabia have reported prevalence rates and risks, the quality of such studies need to be subjected to rigorous assessment and their findings pooled to give combined weighted evidence that will provide basis for targeted intervention. Pooled risks have the advantage of adjusting inherent variations within sampled populations and therefore providing more reliable estimates even though there are concerns about possible magnification of smaller individual risks.

Migration of health workers ‘Brain drain’ is defined as the movement of health personnel in search of a better standard of living and life quality, higher salaries, access to advanced technology and more stable political conditions in different places worldwide. The debate about migration of health workers from the developing to the developed world has remained pertinent for decades now. Regardless of the push and pull factors, migration of health care workers from developing countries to developed ones, have done more harm than good on the health care deliveries in the developing countries. This article reviews the literature on the effects of cross-border migration of health care professionals.
