"Its all in the blood," nutritionist and dietitians often say to their clients. Indeed, much of the evidence about our nutritional status is provided by the blood. Health care practitioners study the blood to determine how well, or poorly we are eating and whether it is deficient or abnormal in any way.

Following the reported transmission of human immunodeficiency virus (HIV) from United States dentist to three of his patients, the World Health Organization (WHO) received requests from a number of countries for practical guidance on how to avoid such incidents. The WHO Global Programme on AIDS (GPA) accordingly organized a consultation of international experts on HIV and hepatitis B virus (HBV) transmission in the health care setting in Geneva on April 11-12, 1991. The consultation report examines the risk of transmission of bloodborne HIV and HBV from patient to patient, from patient health-care worker, and from health care worker to patient. Transmission by any of these pathways is rare, and the third pathway is the rarest of all. For HIV, the United dentist-to-patient case is the only reported instance of its kind (AU)

A brief look at the risks of transmission of the HIV virus to health care workers and what preventative measures should be employed to lower these risks. The article mentions briefly the use of protective barriers and emphasizes the importance of the implementation of recommendations such as initial orientation and training about the epidemiology, modes of transmission and prevention of transmission of HIV and other blood borne infections. Provision of equipment and supplies necessary to minimize the risk of infection

The aetiology of acute painful episodes in patients with sickle cell anaemia is unclear. There is no agreement as to the role of acidosis, and though body fluid changes may be of importance, only plasma volume measurements have been reported. We have therefore measured plasma volume, total body water, and extracellular fluid spaces during painfull crises and after recovery. Patients were males with proven homozygous sickle cell (HbSS) disease, in the age group 16 to 25 years. "Steady state" patients were attending sickle cell clinic and had no other illness. Patients in painful crises had fever and generalized pains and were studied within 36 hours of the onset of crisis. They were regarded as having recovered when significant pain and fever had subsided. Controls were healthy young volunteers, whose sickle cell test was negative and who were not anaemic. Plasma volume, total body water (T.B.W.) and extracellular fluid (E.C.F.) space were measured with Evan,s Blue, tritiated water and insulin repectively. The T.B.W: of 11 patients in the "steady state" was normal, 67.7ñ2.7 percent of body weight (meanñS.D.) compared with 66.6ñ2.6 percent in 7 normal controls: The mean plasma volume of these "steady state" patients was increased - 78.3ñ3.9 ml/kg per Kg compared with 54.1ñ8.4 mls/Kg in 7 controls. T.B.W. was greater during painful crisis than after recovery in five patients showing increases ranging from 1-11 percent of body weight. The plasma volume of these five patients showed no consistent change. In four patients in the "steady state" the E.C.F. volume as a percent of body weight was 23.0ñ1.5 percent compared with 20.5ñ5 percent for four normal controls. During painful crises in two patients the E.C.F. was expanded (33 percent and 32 percent of body weight) as compared with recovery values. It is suggested that the major body fluid compartment change during painful sickle cell crisis in an increase in total body water, and that this probably due to an increase in extra-cellular fluid (AU)

Twenty-eight malnourished children were studied on admission to hospital and during therapy and recovery. Measurements of total body potassium, body fluid compartments and 24-hr urinary creatinine were made. Total body potassium was low in almost all malnourished children, but was lower in those children with clinical oedema. There was a significant decrease in concentration of potassium in intracellular water in malnutrition. The concentration of intracellular potassium was linearly correlated with the total body potassium. Total body water was increased initially and fell with recovery. This increase was borne by the extracellular fluid. The increase in extracellular fluid was correlated with the reduction in total body potassium as well as with the weight deficit. Total body potassium was linearly related to the 24-hr urinary creatinine. Calculations of the contribution of muscle potassium to total body potassium from the creatinine data lead to the conclusion that in children recovering from malnutrition, alterations in muscle protein turnover alter the figures usually given for the relationship of urinary creatinine to muscle mass. The relationships between total body potassium, body weight and height are presented. Height bore a stronger relationship to the total body potassium than did the cube of the height (AU)
