In a prospective study conducted between July 1995 and June 1996 the prevalence of intestinal parasites is described in 35 (32 male, 3 female) patients with hepatic cirrhosis, aged 13-77 years, who had been admitted to the gastroenterology unit of the Federal University in Juiz de Fora, Brazil. The causes of cirrhosis were: alcohol (19 cases), hepatitis B virus (HBV) (3 cases), hepatitis C virus (HCV) (5 cases), HBV and HCV (2 cases), cryptogenetics (3 cases), Wilson's disease (1 case), biliary cirrhosis (1 case), and Gaucher's disease (1 case). Another 45 patients who were hospitalized during this period served as controls (Group I). Group II was comprised of 1411 persons who underwent parasitological tests during December 1995 and May 1996. Comparison was also made with 7371 tests performed in children aged 7-14 years who had been studied in 1988. Stools were examined by the Hoffman-Pons-Janner, Baermann-Moraes, and Willis methods. The results of stool exams were compared with those of the two control groups. A higher prevalence of some parasites was observed in cirrhosis patients than in patients with other digestive diseases (Group I). Of the 35 cirrhosis patients, 19 presented with positive parasite tests. Strongyloides stercoralis was found in 40.2%, chiefly in alcoholic cirrhosis patients, which was significant when compared to the other two control groups, but not significant when compared to the patients with nonalcoholic cirrhosis (4 cases of strongyloidiasis out of 16 patients). None of the 45 patients in Group I had strongyloidiasis. Group II (including all the people who had stool samples examined during the same period in the hospital) had a 1.91% rate of helminthic infection. A rate of 13.16% was found in the children's group.

As the end of this century approaches, the pressure of migration is increasing. It is difficult to limit with restrictive measures the number of refugees and persons seeking asylum in Europe in each country, medical screening programs are organised for arriving refugees and asylum seekers. In Switzerland, they are screened for tuberculosis and hepatitis B. They are offered standard vaccinations and immunized for hepatitis B according to screening results. The prevalence of tuberculosis in asylum seekers is 414 per 100,000, 227 per 100,000 of bacteriologically active tuberculosis. Anti-HBc antibody is present in 22% of women and 39% of men. The frequency increases with age and varies greatly according to origin. Initially, refugees were screened for intestinal parasites. Over a quarter were carriers, a large majority asymptomatic. Increasing numbers of asylum seekers come from countries affected by war and insecurity. Systematic screening carried out in Geneva for previous exposure to violence revealed that 61% reported major trauma, 18% reported torture and 37% complained of symptoms such as nightmares, insomnia, flashbacks, etc. The authors discuss issues related to medical screening programs, and their relative usefulness in an increasingly mobile world where the distinction between travellers and migrants is not always clear.

We investigated the prevalence of peripheral blood abnormalities, parasitic infestation, and hepatitis virus infection, by using the results of the primary screening health checkups for 423 students (male: 317, female: 106, average age +/- SD: 34.2 +/- 5.5 year-old) from abroad. Most of them were from Southeast Asia, Africa, Central and South America, and other developing countries in tropical or subtropical areas. Thalassemia-like hematological disorders, showing microcytic peripheral red blood cells without any anemia, were seen in 7.6 percent of the students, and intestinal parasites were revealed in 12.7 percent of them. The positive rate for anti-hepatitis A virus antibodies (84.3%) and the exposure rate of hepatitis B viruses (35.3%) were similar to previous reports. Compared with the positive rate for anti-hepatitis C virus antibodies (anti-HCVAb) of students from other regions (1.5%), a significantly high seropositivity for anti-HCVAb was encountered in Egyptian participants (21.1%). In recent years, population shifts and rapid transportation have facilitated the spread of certain infectious diseases from endemic to non-endemic areas. International preventive strategies, education of people regarding infectious diseases, and sufficient medical staffs for this purpose are urgently recommended.

Oman is generally hot and dry, but the Salalah region in southern Dhofar province is relatively cool and rainy during the summer monsoon, and has a distinctive pattern of infection. Important, notifiable infections in Oman include tuberculosis, brucellosis (endemic in Dhofar), acute gastroenteritis, and viral hepatitis: 4.9% of the adults are seropositive for hepatitis B surface antigen and approximately 1.2% for hepatitis C virus. Infection with human immunodeficiency virus is uncommon, and leprosy, rabies, and Crimean-Congo hemorrhagic fever are rare. Between 1990 and 1998, the incidence of malaria, (>70% due to Plasmodium falciparum) decreased from 32,700 to 882 cases. Cutaneous and visceral leishmaniasis (caused by Leishmania tropica and L. infantum, respectively) and Bancroftian filariasis occur sporadically. Intestinal parasitism ranges from 17% to 42% in different populations. A solitary focus of schistosomiasis mansoni in Dhofar has been eradicated. There are major programs for the elimination of tuberculosis, leprosy, and malaria, and to control brucellosis, leishmaniasis, sexually transmitted diseases, trachoma, acute respiratory infection in children, and diarrheal diseases. The Expanded Program on Immunization was introduced in 1981: diphtheria, neonatal tetanus, and probably poliomyelitis have been eliminated.

Foreign adopted children and children of asylum applicants and refugees, newly arrived in Denmark, often have lived under conditions that make the following diagnostic considerations relevant: scabies, lice, impetigo and fungal skin infections, nutritional iron deficiency or bleeding, anaemia caused by hook worms in the gastrointestinal tract, malaria, tuberculosis, hepatitis B, HIV infection and various intestinal parasites. Haemoglobinopathies including sickle cell anaemia and talassaemia should also be kept in mind in anaemia. Immigrant children are admitted to hospital approximately twice as frequently as Danish children but with the same diagnoses apart from some increased frequency of psychological and behavioural disturbances and talassaemia.

This article, based on information from specialists at Johns Hopkins, poses and then answers 3 broad questions about the acquired immunodeficiency syndrome (AIDS). 1st, it is asked, "What is AIDS and how serious is it?" It is noted that AIDS is only 1 of several forms taken by infection with the human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). The earliest form of infection is believed to occur within a few weeks of exposure to the virus, and some patients develop an acute syndrome that resembles infectious mononucleosis. These symptoms disappear after 4-6 weeks, by which time the patient has developed antibodies to the virus. About 2-4%/year of asymptomatic carriers go on to develop AIDS-related complex (ARC), and 15-30% of ARC patients develop AIDS within 5 years. The 2nd question posed is, "How do you catch AIDS?" To cause infection, the virus must go directly into the blood, although the virus alone may not be enough to cause sickness. Previous viral infections such as hepatitis B, herpes, cytomegalovirus, and intestinal parasites have been suggested as co-factors of AIDS. Promiscuity increases the chances of contracting AIDS. Observations of the families of AIDS patients and health care personnel who work with AIDS patients suggest that AIDS cannot be caught by casual contact. Finally, it is asked, "What is being done about AIDS?" 4 strategies are outlined: 1) as a result of donor screening for antibodies to HTLV-III/LAV, AIDS has been completely removed from the blood banks; 2) virologists are attempting to understand the virus so that it can be attacked, and understanding has been advanced by the theory that HTLV-III might be what is called a "slow virus;" 3) education about AIDS is changing the sexual practices that transmit AIDS; and 4) epidemiologists are carefully following those who are at risk, have been exposed, or are already sick.

Nearly 220,000 children have been adopted from other countries by American parents since 1986. Approximately 65,000 children have arrived from China and Russia, mostly in the past 6 years. Most of these children reside in orphanages before adoption, where they may experience malnutrition, environmental deprivation, neglect, and exposure to infectious diseases. After arrival to the United States, international adoptees should undergo specialized screening evaluation for infectious diseases and other conditions. Infectious conditions of special concern include hepatitis B and C, syphilis, human immunodeficiency virus infection, tuberculosis, and presence of intestinal parasites. Before the adoption occurs, the infectious disease consultant may be asked to assist the primary care provider and the adoptive family with advice about travel and review of preadoptive medical records. After the adoption, the infectious diseases consultant may be asked to assess the adequacy of the child's vaccination record from the birth country and to assist in screening, evaluation, and management of infectious diseases.

Over the past 10 years the United States has resettled an average of 106,500 refugees annually (U.S. Committee for Refugees: Refugee Rep 1999; 20(12):1-12), relocating them to various cities across the country. Upon arrival, some states offer refugees physical health screening, specifically for communicable diseases such as tuberculosis, intestinal parasites and Hepatitis B, and for general preexisting medical problems. Unfortunately, the same attention is rarely given to potential mental health needs. Research has shown that refugees are at greater risk for depression, anxiety, and posttraumatic stress syndrome than the general U.S. population, yet they are not routinely screened. The purpose of this paper is to describe the addition of an innovative program for mental health screening in a refugee population. The current study found that mental health screening was more effective when done in a home visit situation. A 23.8% rate of depression was found amongst those refugees screened.

International adoptions have become increasingly common in the United States. Children awaiting international adoption and families traveling to adopt these children can be exposed to a variety of infectious diseases. Compared with the United States, foreign countries often have different immunization practices and methods of diagnosing, treating, and monitoring disease. Reporting of medical conditions can also differ from that of the United States. The prevalence of infectious diseases varies from country to country and may or may not be common among adopted children. The transmission of tuberculosis, hepatitis B, and measles from adopted children to family members has been documented. Furthermore, infectious organisms (e.g., intestinal parasites), bacterial pathogens (e.g., Bordetella pertussis and Treponema pallidum), and viruses (e.g., human immunodeficiency virus and hepatitis viruses) may cause clinically significant morbidity and mortality among infected children. Diseases such as severe acute respiratory syndrome or avian influenza have not been reported among international adoptees, but transmission is possible if infection is present. Family members may be infected by others during travel or by their adopted child after returning home. Families preparing to adopt a child from abroad should pay special attention to the infectious diseases they may encounter and to the precautions they should take on returning home.

Refugee children, although in generally good health, may present with unfamiliar infectious or hematological problems, primarily tuberculosis, hepatitis B, intestinal parasites, malaria, eosinophilia and anemia. Prevalence, clinical features and treatment are discussed, together with the features of some less common infections. In the symptomatic refugee child, both common and exotic infectious diseases should be considered in the differential diagnosis. Iron deficiency and hemoglobinopathies should be considered in the differential diagnosis of microcytic anemia.
