The ethical distribution of health care is a central issue now that AIDS has started to be a drain on health care resources. If the worst predictions are true, the next half century will be capitalized by a great stress of the health care delivery system in the Pacific. The critical challenges that face the current leadership are: sustaining commitment to all levels of administration to reduce social and health inequities; making sound decisions on policies, priorities and goals that are based on valid information; strengthen health infrastructure, based on the principle of primary health care, including appropriate distribution of staffing, skills, technology and resources. The goals of the Pacific Health Promotion and Development center must not focus exclusively on AIDs. Hepatitis B control measures, hypertension and diabetes, primary care in remote areas, and rehabilitation initiatives must be kept in place. Humanitarian interests for AIDs patients must be balanced with the pragmatic reality of saving children's hearing, or extending useful lives. The attributes of respect, accountability, leadership, judgement, fairness, integrity and honesty controlled by principles of social justice must be part of the administrative decision making process. The 2 major issues facing public health professional are: (1) the financial considerations involved with increasingly expensive technology, services and research, contrasted against the need to prioritize their use and development; (2) pragmatic and ideological needs must be balanced to maximize preventative and curative services and make them available to those who can benefit from them.

The traditional options available for the correction of hemodialysis-related anemia are blood transfusions and androgen therapy to stimulate erythropoiesis. A new therapeutic option, recombinant human erythropoietin (r-HuEPO; EPOGEN, AMGEN Inc, Thousand Oaks, CA), is currently undergoing clinical trials. Each treatment alternative has certain attendant adverse effects. The adverse effects of transfusion include transmission of infections such as hepatitis or acquired immunodeficiency syndrome, iron overload, and sensitization to histocompatibility antigens. Androgen therapy can cause masculinization of women and children and, in some forms, is associated with a high incidence of abnormal liver function. Treatment with r-HuEPO has some potential adverse effects, including hypertension, thrombosis of arteriovenous fistulae, prolonged duration of dialysis, hyperkalemia, and iron deficiency. Gradual and careful introduction of r-HuEPO should prevent hypertension from becoming problematic.

The chemistry, pharmacology, pharmacokinetics, clinical uses and efficacy, adverse effects, drug interactions, dosage and administration, and formulary considerations of epoetin are described. Erythropoietin, a glycoprotein hormone primarily synthesized in the kidney, is the chief regulator of red blood cell production. Erythropoietin concentrations increase in response to a hypoxic state, resulting in increased red blood cell formation, accelerated hemoglobin production, and premature movement of reticulocytes into the circulation. The human gene responsible for the production of erythropoietin recently was cloned, and the recombinant product--epoetin--has been made available through mass production. The apparent volume of distribution of i.v. epoetin approximates the assumed plasma volume both in healthy volunteers and in patients with chronic renal failure. Little is known about the metabolism and route of elimination of epoetin and erythropoietin. Epoetin recently was approved by the FDA for treatment of anemia associated with chronic renal failure. Clinical trials in patients receiving hemodialysis or peritoneal dialysis and in predialysis patients with renal dysfunction demonstrate epoetin's efficacy. Other potential indications include augmentation of blood production in patients enrolled in autologous blood donation programs and treatment of anemias associated with rheumatoid arthritis, sickle cell disease, acquired immunodeficiency syndrome, cancer, and premature birth. The most frequent adverse effect associated with epoetin therapy is the worsening or development of hypertension. Other adverse effects include thrombocytosis, hyperkalemia, rise in serum urea concentration, iron deficiency, and flu-like symptoms. No drug interactions with epoetin have been reported in humans. The recommended starting epoetin dosage in patients with chronic renal failure is 50-100 IU/kg three times weekly. Epoetin is available only as an injection for i.v. or s.c. administration. Epoetin provides a new therapeutic approach to the treatment of anemia associated with chronic renal failure in hemodialysis, peritoneal dialysis, and predialysis patients. Benefits of epoetin therapy include reduced need for blood transfusions, the amelioration of anemic symptoms, and an improved quality of life.

The mean annual rate of decline of the probability of dying 5 years of age in developing countries is 2.5%. Nevertheless disease accounts for a considerable proportion of premature deaths. The leading causes of death in these countries, in order, include respiratory disease, diseases of the circulatory system, low birth weight, diarrhea, measles, injuries, malnutrition, and neoplasms. These conditions represent diseases of poverty and affluence. Respiratory infections are common among 5-year old children and cause a high proportion of child deaths. Circulatory diseases tend to be limited to adults. Control of hypertension, diet, smoking prevention, and exercise can prevent circulatory diseases. The risk of dying in infancy and childhood and of developmental disabilities is higher among low birth weight infants than those who weigh 2500 gm. In Bangladesh, 50% of infants weight 2500 gm. Low birth weight is the underlying cause of death for many infants who die of respiratory infections and diarrhea. Oral rehydration can successfully treat most diarrhea cases. Malnutrition and diarrhea tend to occur together and feed off each other. In fact malnourished people are more susceptible to all infections. Malnourished children suffer from disabilities in development and growth. The greatest sufferers of measles are infants and malnourished children. Immunization of all =or 9-month old infants would eradicate measles. Children and young adults are at the highest risk of injuries. Lung cancer is on the rise in developing countries due to the increase of tobacco smoking. Various means of controlling malaria are use of mosquito nets, antimalarial drugs, reduction of mosquito breeding places, and pesticides. The new infectious disease, AIDS, has emerged as a considerable health problem in developing countries. High priority research areas are vaccines for Streptococcus pneumonia, Plasmodium app., rotavirus, Salmonella typhi (Ty21a), and Shigella spp.

Since 1981, the Centers for Disease Control has collaborated with State health departments and the District of Columbia to conduct random digit-dialed telephone surveys of adults concerning their health practices and behaviors. This State-based surveillance system, which yields data needed in planning, initiating, and supporting health promotion and disease prevention programs, is described in this paper. Standard methods and questionnaires were used to assess the prevalence of personal health practices and behaviors related to the leading causes of death, including seatbelt use, high blood pressure control, physical activity, weight control, cigarette smoking, alcohol use, drinking and driving, and preventive health practices. Between 1981 and 1983, 29 States (includes the District of Columbia) conducted one-time telephone surveys. Beginning in 1984, most States began collecting data continuously throughout the year, completing approximately 100 interviews per month (range 50-250), with an average of 1,200 completed interviews per year (range 600-3,000). The raw data were weighted to the age, race, and sex distribution for each State from the 1980 census data. This weighting accounts for the underrepresentation of men, whites, and younger persons (18-24 years) in the telephone surveys and, for many health practices, provides prevalence estimates comparable with estimates obtained from household surveys. Nearly all (86 percent) of the States distributed selected survey results to other State agencies, local health departments, voluntary organizations, hospitals, universities, State legislators, and the press. The majority (60 percent) of States used information from the surveys to set State health objectives, prepare State health planning documents, and plan a variety of programs concerning antismoking, the prevention of chronic diseases, and health promotion. Further, nearly two-thirds (65 percent) used results to support legislation, primarily related to the use of tobacco and seatbelts. Most of the States (84 percent) reported that alternative sources for such data (prevalence of behavioral risk factors) were unavailable. Currently in 1988, over 40 State health departments are conducting telephone surveys as part of the Behavioral Risk Factor Surveillance System. This system has proved to be (a) flexible--it provides data on emerging public health problems, such as smokeless tobacco use and AIDS, (b) timely--it provides results within a few months after the data are collected, and (c) affordable--it operates at a fraction of the cost of comparable statewide in-person surveys. The system enables State public health agencies to continue to plan,initiate, and guide statewide health promotion and disease prevention programs and monitor their progress over time.

The Stress Clinic at the Maudsley Hospital investigates anxiety due to stress and its pharmacological treatment. Nine stress areas are investigated and their relative severities estimated: social habits, social relationships, life events, psychiatric morbidity, sexual stresses, sleep, stress in old age, menstrual stresses and stress and the heart. From the results a Stress Profile can be constructed for each patient to compare the importance of these different stresses and this can also be used as a measure of change in response to treatment. The benzodiazepine (BZD) anxiolytics can be divided into two groups according to duration of action, medium (8-12 h) and long (30-100 h). Short-acting BZD drugs are particularly useful for situational anxiety, when treatment can be interrupted over night and at weekends. To overcome problems of dependence, withdrawal effects, and daytime side-effects, new non-BZD anxiolytics have been developed: buspirone, alpidem and suriclone. These may be particularly useful for long-term treatment of anxiety. Another alternative is the use of adrenergic beta-blocking drugs of which propranolol and betaxolol have been used in the Clinic, because of their relatively high concentration in the brain when taken orally. Anxiety accompanying coronary heart disease and hypertension can be controlled with anxiolytic drugs and other illnesses with an anxiety component are: sexual disorders, menstrual disorders, asthma, gastro-intestinal conditions, dermatological conditions and chronic illnesses such as malignancy and AIDS. Lack of sleep is a subtle form of stress exerting an adverse effect in almost every illness known to man. BZD hypnotics can be divided into four groups: ultra-short-acting (3-4 h), short-acting (5-6 h), medium-acting (7-8 h) and long-acting (9-12 h). Depending on the nature of the insomnia, ultra-short-acting and short-acting BZD are particularly convenient with minimal disadvantages. Nevertheless, new non-BZD hypnotics are also being developed, i.e. zolpidem and zopiclone. These drugs are relatively short-acting and of equivalent potency to the BZD without problems of dependence etc. Anxiety, as either cause or effect, accompanies many medical illnesses and the use of anti-anxiety drugs as concomitant therapy can both reduce morbidity and improve prognosis.

The existence of an HIV-related nephropathy as a distinct disease entity is controversial. We observed a high incidence of renal disease in our AIDS patients. Of 182 patients, 59 patients (32.4%) were found to have heavy proteinuria (greater than 2 g/24 h). Of these, 24 patients had slow progression of renal insufficiency and 2 patients had rapid deterioration to end stage renal disease. There was a notable absence of hypertension in these cases. The incidence of proteinuria was similar in blacks and hispanics; however 22.8% of blacks had renal insufficiency as compared to 6.9% of hispanics. There was no difference in the incidence of heavy proteinuria between intravenous drug abusers (32.3%) and nonabusers (33.3%). Renal morphology when examined showed characteristic changes, including cytomembranous structures and virus-like particles. These changes were similar in patients with heavy or light proteinuria, though they were less severe in the latter. We conclude that a HIV-related nephropathy exist and the presence of cytomembranous structures and virus-like particles in the renal tissue raises the possibility of a viral etiology for this disorder.

Cyclosporin (7.5 mg/kg daily) was given to 8 AIDS patients for 17-66 days and to 25 HIV-seropositive non-AIDS patients, 15 with stage II (T4 cells/microliter greater than or equal to 300, less than 600) and 10 with stage III (T4/microliter less than 300), for 3-6 months with the hypothesis that the drug could inhibit both HIV replication and the potential autoimmune component of HIV disease. A sustained increase over 600 T4/microliter occurred in 7 patients with stage II and 1 with stage III. T8 cells significantly decreased in most patients and lymphadenopathy disappeared in 14/16. After cyclosporin withdrawal T4 and T8 cells as well as lymphadenopathy returned to pretreatment status. Cyclosporin side effects (hypertension, creatinine increase, and anemia) were moderate and reversible. These results might stimulate biological research as well as clinical trials with cyclosporin in selected groups of HIV-seropositive subjects with the aim of delaying or preventing AIDS occurrence.

Garlic may play an invaluable role in the prevention and therapy of the major causes of death. Anecdotal, basic, and clinical research data are confirming the efficacy of this herb in the treatment of hyperlipemia, cancer, heavy-metal intoxication, infectious diseases, hypertension, free-radical damage, and immune deficiency states. Garlic's broad antimicrobial spectra and its ability to modulate immunity may play a strategic role in the acquired immunodeficiency syndrome pandemic. A review of the literature supports a greater scrutiny of this herb's therapeutic potential.

The cotton-wool spot is a common fundus finding in patients with many ocular and systemic diseases. We investigated the characteristics of cotton-wool spots in patients with four major diseases, ie, acquired immunodeficiency syndrome, diabetes mellitus, systemic hypertension, and central retinal vein occlusion, to see if any differences were detected in their number, size, or location. A composite of all the cotton-wool spots for each of these four categories was obtained by computed reconstruction to analyze variations in their distribution and size. The cotton-wool spots had a predilection for the temporal quadrants in the four categories and were smaller in patients with acquired immunodeficiency syndrome than the other groups. Patients with ischemic central retinal vein occlusion had more cotton-wool spots than the other groups. No other definite differences were detected. Cotton-wool spots than the other groups. No other definite differences were detected. Cotton-wool spots seem to be a common pathway following various insults to the retina, most probably of a vaso-occlusive origin.
