The HB antigen of the hepatitis B (HB) virus, studied by counter immunoelectrophoresis shows a prevalence of 8.7% in 1,860 rural Malians and 11.3% in 764 blood donors from Bamako. Amongst 1,350 hospitalised patients, no correlation could be established between the HBs antigen chronic carriers state and other infectious diseases, malnutrition or genetic deficiencies. On the other hand, the prevalence of HBs antigen is particularly high in hepatic infections: acute and chronic hepatitis (53.5%), cirrhosis (31.5%) and hepatomas (25.3%). The study of the prevalence of hepatitis B by radioimmunoassay of the HBV seric markers was carried out in: --176 "healthy" town dwellers of which 97.2% were carriers of at least one marker--HBs Ag: 16.5%; anti-HBc alone: 34.1%; anti-HBs: 46.6%--. --30 subjects with cirrhosis--HBs Ag: 66.7%; anti-HBc alone: 10.0%; anti-HBs: 23.3%--. --42 subjects with PHC--HBs Ag: 47.6%; anti-HBc alone: 23.8%; anti-HBs: 28.6%--. The difference in HBs Ag carrier state between patients (cirrhosis and PHC) and controls, cross-matched for sex and age, is highly significative--p = 0,0001--.

S. mansoni and S. japonicum complex schistosomes cause hepatosplenic and hepatointestinal schistosomiasis. The prevalence and incidence of this disease is increasing in all the endemic areas. Hepatosplenic schistosomiasis is seen in a small subset of clinically infected patients and represents a good model of intrahepatic portal hypertension characterised by a presinusoidal portal block and a well preserved liver parenchyma. Symmers' fibrosis is seen in a significant proportion of patients with high worm load. While the pathogenesis of Symmers' pipe stem fibrosis has not been well established, experimental and clinical data point to egg induced granulomata. The main consequences are presinusoidal portal hypertension, oesophageal varices and hepatosplenomegaly. The most striking symptoms are haematemesis or melena secondary to variceal and gastrointestinal bleeding. Cofactors associated with the pathogenesis include aflatoxins, malnutrition, alcoholism, hepatitis B and C virus. While stool examination is the best technique for diagnosis, a number of immunological tests though sensitive are not specific. Ultrasonography is sensitive for detection of Symmer's fibrosis. Praziquantel and oxaminiquine are drugs found to be effective in the treatment of hepatosplenic schistosomiasis. Recently beta-blockers have been found to be effective in the treatment of gastrointestinal rebleeding. Endoscopic sclerotherapy has been found to be effective for treatment of bleeding oesophageal varices. The treatment of choice for portal hypertension is oesophagogastric devascularization with splenectomy (EGDS).

The health profile of two groups of Ethiopian immigrants in Israel was evaluated. Trichophytosis and active trachoma were observed in 5%-8.7% of prepubertal children. Among adults 13% had corneal opacities and 10.4% had cataracts. Goiter, spastic bronchitis, valvular heart disease, leprosy and onchocerciasis were prevalent. Malnutrition was common, with average body weights ranging from 72.4% to 85.2% of normal. Anemia was observed in 6.3% of young children and 70% of all immigrants. Fifty percent of children over 12 years and 98% of adults over 40 years of age had been exposed to hepatitis B virus; 9.8%-11.8% were HBsAg carriers. Tuberculin tests were positive in 9.8%-13%; and intestinal parasites were identified in 86%-98%. Hospitalization was required for 15.7% of immigrants arriving during the period 1978-90, and for 3.7% of those arriving in mid-1991 (Operation Solomon).

The response to recombinant hepatitis B vaccine was assessed in 31 seronegative infants (2-26 months old) with protein calorie malnutrition (PCM), compared with 13 seronegative age- and sex-matched healthy infants. Both groups received three 10 micrograms vaccine doses at 0, 1, and 6 months. At month 8, all healthy infants and 87 per cent (27 out of 31) of PCM infants were seroprotected. Thus, hepatitis B vaccination (Engerix-B, SmithKline Beecham Biologicals) can be used effectively in PCM for mass vaccination in developing communities.

Blood transfusion in Djibouti is organized with reference to relevant French regulation and the recommendations of the World Health Organization. The system is basically family donor system operating on the principle of one tested unit of blood for every two untested units donated. Spontaneous donations mainly from the police and army personnel account for only 20% of the 2500 units collected each year. The principle blood products are adult whole blood, adult red cells, and fresh frozen plasma. Products are distributed after viral and microbial testing for infectious disease. Overall the percentage of blood products that are not released due to detection of infectious agents is 17.5%. This rate is well correlated with the incidence of hepatitis B (15.5%), HIV infection (3.4%), hepatitis C (1.5%) and syphilis (0.4%) in Djibouti. The greatest demand for whole blood comes from medical departments where indigent people are treated for anemia due to dietary deficiency. Contamination by HIV present at undetectable levels at the time of testing is a serious problem. Measures should be taken to prevent anemia due to dietary deficiency and develop the use of autologous transfusion.

The growing number of people seeking asylum in the Netherlands compromises the provision of adequate medical services to all. This development may have a negative impact on refugee children especially. International literature indicates that many children, especially the ones coming from tropical areas or the ones who resided in refugee camps, are suffering from diseases such as tuberculosis, hepatitis B, anaemia, parasitic diseases, caries, malnutrition, hearing and seeing impairments. Many children have psychosocial problems due to traumatic experiences in their country of origin and/or during their flight. These problems lead to a diversity of complaints such as difficulty to sleep, enuresis, feeding problems and hyperactivity. Both the somatic and the psychosocial problems may impede the growth and development of these children. It is therefore imperative to identify the children at risk and to formulate guidelines for providing medical care to refugee children. Special care should also be given to the housing, the living conditions and the provision of specialised personnel and to limiting the duration of the asylum procedure in the case of families with children and other minors.

Lisa Capaldini, a physician who treats patients with HIV-related fatigue, discusses symptoms, diagnosis techniques, and treatments of depression, anemia, and various other roots of fatigue in HIV-positive patients. Biochemical depression, caused by abnormal levels of serotonin and norepinephrine in the brain, is easily misdiagnosed or overlooked. Physical and emotional symptoms of depression mirror common effects of HIV such as exhaustion, anger, and irritability. Knowing the history of depression prior to HIV infection, including previous drug abuse and family history of depression, will help to diagnose fatigue. Dr. Capaldini recommends antidepressants provided the condition is properly diagnosed and the side effects are not harmful to the patient. Selective serotonin reuptake inhibitors (SSRI), the most frequently prescribed antidepressants, can cause short term sexual dysfunction. Bupropion and Wellbutrin can be prescribed to avoid this side effect. Psychotherapy can be effective if therapists are familiar with HIV disease and can distinguish between symptoms brought on by behavior, addictive habits, or pre-existing depression. Consideration also must be given to drug interactions, particularly with the antiretrovirals ritonavir and delavirdine, which can cause seizures or disturb cardiac rhythm. Anemia is most noticeable after physical exertion, and symptoms are more evident based on the increased rate that red blood cells move out of the normal range. To determine the course of treatment, physicians need to clarify the cause of anemia. Anemia can be caused by drugs, vitamin deficiencies, or other nutritional problems. Adrenal insufficiency, methemoglobinemia, and malnutrition are also causes of fatigue. Diagnosing fatigue due to hepatitis B or C, rather than HIV, can be achieved by measuring hepatitis levels and observing T cell counts and viral load. Dr. Capaldini suggests that proper diet and exercise prevent fatigue from getting worse.

Hepatitis C virus (HCV) is one of the leading causes of chronic liver disease. It was first identified in 1989, as being distinct from hepatitis A and hepatitis B. The HCV does not attack the immune system, but rather causes an inflammatory reaction that is localized within the liver, involving the entire organ. About 80% of patients with acute hepatitis C will develop chronic HCV, of which about 20-30% will progress to cirrhosis and its consequences, over 10-20 years. After 20-40 years, a smaller proportion of patients with chronic disease will develop hepatocellular carcinoma. The course and outcome of the disease vary considerably. In some individuals, spontaneous remission occurs over a few years; in others, the disease is more severe, progressing to cirrhosis and end-stage liver disease. Despite biochemical and pathological confirmation of the diagnosis, patients are often asymptomatic for many years. Hepatic failure occurs late in the disease. Factors suggesting a poor prognosis include high serum transaminase levels, active cirrhosis on liver biopsy, and an increased viral load (HCV RNA), as well as associated medical conditions such as alcoholic liver disease, hepatitis B viral (HBV) infection, or human immunodeficiency virus (HIV). Nutrition has been recognized as a prognostic indicator in patients with chronic liver failure. However, standardized approaches for the diagnosis and classification of malnutrition in this population have not been consistently applied before implementing nutrition intervention. Common criteria for the assessment of malnutrition, weight and body mass index (BMI) for example, do not give accurate data in patients with chronic liver disease, complicated by ascites and edema. In addition, the chronic inflammatory reaction of liver failure progresses slowly, so that subtle nutritional deficits are not obvious at early stages of the disease. A review of the literature has been undertaken to identify current nutritional guidelines for patients with hepatitis C as well as chronic hepatitis.

Objective. To assess the health status of delinquent male youths at the time of their admission to a juvenile correctional center.Design. Cross-sectional descriptive study over a 6-year period (1995-2000). Setting. Health primary care. Juvenile correctional center in Zaragoza, Spain. Participants. Two hundred forty male adolescents were admitted during the study period. Mean age was 15 years (SD, 1.3) (range, 13-17 years). Measurements and main results. Health status via medical history and physical examination was assessed according to standard protocols and individualized complementary laboratory examinations were performed. Most frequent health problems were smoking habit (97.1%), drug/alcohol abuse (54.1%), odontologic (40%), psychopathologic disorders (17.1%), incomplete immunization status (16.6%), growth and nutritional disorders (14.5%) growth delay (5.8%), malnutrition (3.3%), overweight (2.1%), obesity (3.3%) , infectious diseases associated with intravenous drug use and/or risk sexual behaviors (10.4%) hepatitis C (4.6%), hepatitis B (2.9%), AIDS (2.1%), syphilis (0.8%) , dermatological (10%), opthalmological (7.5%), and respiratory (5%). Less prevalent health problems were orthopedic (3.3%), anemia (3.3%), otic (2.5%), cardiovascular (2.5%), and intestinal parasitism (1.6%). Conclusions. Early intervention during the stay into juvenile correctional center regarding their physical health and especially their mental health, from the sanitary and educative viewpoint, presents a unique opportunity to solve the basic health needs of these high-risk adolescents.
