The Roma Population Living in Segregated Settlements in Eastern Slovakia Has a Higher Prevalence of Metabolic Syndrome, Kidney Disease, Viral Hepatitis B and E, and Some Parasitic Diseases Compared to the Majority Population.

Background: The Roma population is one of the largest marginalized population groups in Europe. The aim of our work was to summarize the morbidity of lifestyle-related diseases and infectious diseases in the Roma population living in segregated settlements. Methods: We used data from the cross-sectional study HepaMeta, in which we examined 452 Roma subjects with an average age of 34.7 ± 9.1 years, 35.2% of which were men, and 403 non-Roma subjects with an average age of 33.5 ± 7.4 years, 45.9% of which were men. We collected data by means of a questionnaire, anthropometric measures, and we analyzed blood and urine samples. Results: Roma subjects had a higher incidence of metabolic syndrome (RR: 1.478 (1.159-1.885), p < 0.0001), obesity or waist circumference >94 cm in men/80 cm in women (RR: 1.287 (1.127-1.470), p < 0.0001), and HDL-C < 1.03 mmol/L in men or <1.29 in women (RR: 2.004 (1.730-2.321), p < 0.0001) than their non-Roma counterparts. Subjects of the Roma population were more frequently diagnosed with kidney disease (RR: 1.216 (1.096-1.349), p < 0.0001), HBsAg positivity (RR: 4.468 (2.373-8.415), p < 0.0001), anti HBc IgG positivity (RR: 3.13 (2.598-4.224), p < 0.0001), and anti HEV positivity (RR: 2.972 (1.226-7.287), p < 0.0001). Serological markers of Toxoplasma gondii infection and Toxocara spp. were observed much more frequently among Roma than non-Roma subjects (RR: 1.868 (1.520-2.296), p < 0.0001, for Toxoplasma gondii; and RR: 21.812 (8.097-58.761), p < 0.0001, for Toxocara spp.). Conclusions: Poor socio-economic conditions, an unhealthy lifestyle, and barriers precluding access to healthcare are factors that affect the Roma population in settlements and lead to an increased prevalence of metabolic syndrome and its components, kidney disease, viral hepatitis B and E, and some parasitic diseases.

Microbiological screenings for infection control in unaccompanied minor refugees: the German Armed Forces Medical Service's experience.

BACKGROUND: The German Military Medical Service contributed to the medical screening of unaccompanied minor refugees (UMRs) coming to Germany in 2014 and 2015. In this study, a broad range of diagnostic procedures was applied to identify microorganisms with clinical or public health significance. Previously, those tests had only been used to screen soldiers returning from tropical deployments. This instance is the first time the approach has been studied in a humanitarian context. METHODS: The offered screenings included blood cell counts, hepatitis B serology and microscopy of the stool to look for protozoa and worm eggs as well as PCR from stool samples targeting pathogenic bacteria, protozoa and helminths. If individuals refused certain assessments, their decision to do so was accepted. A total of 219 apparently healthy male UMRs coming from Afghanistan, Egypt, Somalia, Eritrea, Syria, Ghana, Guinea, Iran, Algeria, Iraq, Benin, Gambia, Libya, Morocco, Pakistan, and Palestine were assessed. All UMRs who were examined at the study department were included in the assessment. RESULTS: We detected decreasing frequencies of pathogens that included diarrhoea-associated bacteria [Campylobacter (C.) jejuni, enteropathogenic Escherichia (E.) coli (EPEC), enterotoxic E. coli (ETEC), enteroaggregative E. coli (EAEC), enteroinvasive E. coli (EIEC)/Shigella spp.), Giardia (G.) duodenalis, helminths (comprising Schistosoma spp., Hymenolepis (H.) nana, Strongyloides (S.) stercoralis] as well as hepatitis B virus. Pathogenic microorganisms dominated the samples by far. While G. duodenalis was detected in 11.4% of the assessed UMRs, the incidence of newly identified cases in the German population was 4.5 cases per 100,000 inhabitants. CONCLUSIONS: We conclude that the applied in-house PCR screening systems, which have proven to be useful for screening military returnees from tropical deployments, can also be used for health assessment of immigrants from the respective sites. Apparently healthy UMRs may be enterically colonized with a broad variety of pathogenic and apathogenic microorganisms. Increased colonization rates, as shown for G. duodenalis, can pose a hygiene problem in centralized homes for asylum seekers.

[Asylum-seekers' mental and physical health problems: practices and recommendations]. / A menedékkérok mentális és fizikai egészségproblémái: gyakorlatok és ajánlások.

The Hungarian health care system faces new challenges with the unprecedented increased rate of migration. Asylum-seekers arriving are a heterogeneous group. Their health care needs vary depending on their country of origin and the quality of the health care they received prior to arrival, not to mention the impact of the migration process on their health. Described within this paper are the challenges an asylum seeker might face in obtaining care on arrival into the host country and the challenges clinicians face in providing that care. This review is designed to give health professionals the necessary knowledge to care for asylum-seekers in a culturally aware and clinically informed manner.

Infectious Diseases in Immigrant Population Related to the Time of Residence in Spain.

The aim of this study was to evaluate the data on the main imported infectious diseases and public health issues arising from the risk of transmission of tropical and common diseases in the immigrant population. During the period of study, 2,426 immigrants were attended in the Tropical Medicine Unit of the Hospital of Poniente. For each patient, a complete screening for common and tropical diseases was performed. The prevalence and main features of intestinal and urinary parasites, microfilarias, Chagas disease, malaria, hepatitis B (HBV) and C (HCV) viruses, extrapulmonary tuberculosis and syphilis was investigated taking into account the length of stay in Spain. Sub-Saharan Africa patients who had lived for <3 years in Spain had a high significantly number of infections produced by hookworms, Ascaris lumbricoides, Trichuris trichiura, Schistosoma mansoni, Giardia lamblia, Entamoeba histolytica/dispar and Plasmodium spp. In patients who had lived for more than 3 years, there were significantly high rates of HBV infections, although HBV rates in sub-Saharan African patients are high even if the patients have been in Spain for <3 years. However, patients with large stays in Spain had also an important number of parasitological diseases. The main objective of the diagnosis is to avoid important public health problems and further complications in patients. It is advisable to carry out a screening of the main transmissible infections in all immigrant population regardless of the time outside their country. This screening should be individualized according to the geographical area of origin.

[Imported parasitic diseases in the immigrant population in Spain]. / Parasitosis importadas en la población inmigrante en España.

BACKGROUND: Migration has contributed to the emergence of certain infectious diseases in host countries. In Spain the number of immigrants has increased exponentially in recent decades. The aim of this review is to identify and analyze the available information on imported parasitic diseases in immigrant population in our country. METHODS: A scope review of original articles published on imported parasitic diseases between 1998 and 2012. Study populations from Latin America, Africa, Asia, Eastern Europe and individuals who are under the definition of an immigrant from International Organization for Migration were included. The literature search was performed in the Medline and MEDES-MEDicina databases. RESULTS: A total of 51 descriptive studies were included in the analysis. Most immigrants attended at referral health facilities were originally from sub-Saharan Africa (between 16%-87%), followed by Latin America (13%-37%), while Asia was the region less represented (0.2%-8.8%). A considerable proportion (6.5-31%) of immigrants that attended to referral units of tropical medicine or inmigrant health, and that were originally from Latin America, particularly those from Bolivia, are affected by the Chagas disease, and several cases of mother-to-child transmission have been registered in our country. CONCLUSION: Imported parasitosis is a frequent diagnosis among migrant population. This review highlight the impact that migration has had on the emergence of certain imported parasitic diseases, being Chagas disease the most paradigmatic example.

Differences in prevalence of parasites in stool samples between three distinct ethnic pediatric populations in southern Israel, 2007-2011.

Intestinal parasites cause significant morbidity worldwide, particularly in developing populations. At least three pediatric populations reside in southern Israel: the Bedouin population, the general Jewish population and Jewish children of Ethiopian origin. Our aim was to compare intestinal parasite prevalence between the three pediatric populations in southern Israel. This is a retrospective, laboratory, population-based surveillance. Most ova and parasite (O&P) tests in southern Israel (hospital and community obtained) are performed by the hospital parasitology laboratory. All pediatric stool O&P tests examined by the hospital laboratory between 2007 and 2011 were included. Overall, 45,978 samples were examined; 27,354, 16,969 and 1655 from Bedouin, non-Ethiopian Jewish and Ethiopian children, respectively. 16,317 parasites were identified in 12,325 (26.8%) positive samples. Total prevalences were 36%, 11% and 46% for Bedouin, non-Ethiopian Jewish and Ethiopian children, respectively. Blastocystis hominis, Giardia lamblia and Entamoeba species were the most common parasites identified, constituting ≥80% of positive samples in all groups. Hymenolepis nana was rarely identified in non-Ethiopian Jewish children (0.04% of isolates compared with 2.6% and 0.5% in Bedouin and Ethiopian children, respectively). Other helminths, excluding H. nana and Enterobius vermicularis, were identified almost exclusively in Ethiopian children ≥5years of age. In conclusion, the Bedouin and Ethiopian children were characterized by higher parasite prevalence in stool, compared with the non-Ethiopian Jewish children, probably reflecting higher intestinal parasitic disease rates. Certain helminthic infections were identified almost exclusively in the Ethiopian children. These differences may be associated with lifestyle differences between the three populations.

[Radiological findings in patients with imported schistosomiasis]. / Hallazgos radiológicos en pacientes con esquistosomiasis importada.

INTRODUCTION: Imaging techniques, primarily ultrasound, are useful in the diagnosis and monitoring of patients with schistosomiasis in endemic areas. METHODS: Study of 219 patients treated in sub-Saharan Tropical Medicine Unit with a diagnosis of imported schistosomiasis by imaging techniques investigations including plain abdominal radiography and ultrasound. RESULTS: A total of 17.8% of patients who had an abdominal X-ray showed findings suggestive of schistosomiasis, in most cases bladder calcifications. In 73 patients (41%) ultrasound showed pathological findings, mainly diffuse or focal wall thickening (26 patients), nodular lesions (n=14), and pseudopolyps (n=8). One patient, who had a large bladder mass (9cm) and bilateral ureterohydronephrosis, was finally diagnosed with squamous cell carcinoma of the bladder. Ultrasound liver abnormalities were found in 10 patients, 4 with signs of portal hypertension, of which 3 had the characteristic periportal fibrosis in schistosomiasis. CONCLUSION: Imaging studies, especially abdominal and bladder ultrasound, are useful for diagnosis, the study of disease and monitoring of patients with schistosomiasis in non-endemic countries.

Primer reporte de pseudomiasis intestinal humana por Eristalis tenax (Diptera, Syrphidae) en zona semiárida urbana del estado Falcón, Venezuela / First report of human intestinal pseudomiasis by Eristalis tenax (Diptera, Syrphidae) in urban semiarid area from Falcon state, Venezuela

Pseudomiasis es el término empleado cuando se considera que las larvas y/o huevos de moscas se adquieren accidentalmente per os y atraviesan con inmediatez a lo largo del tracto digestivo. Se documenta un caso de una pseudomiasis intestinal por larvas de Eristalis tenax (Diptera: Syrphidae) en una paciente femenina de 39 años de edad, proveniente de un sector periférico de la ciudad de Coro, estado Falcón, Venezuela. La paciente observó inmediatamente la presencia de la larva viva en sus heces. Aunque refirió sufrir eventualmente de cólicos, al examen físico se presentó normal. La paciente aparentemente no sufre de trastornos mentales, y posee un nivel socioeconómico bajo. El presente trabajo constituye el primer reporte documentado de una pseudomiasis entérica por E. tenax en la zona semiárida del estado Falcón, en la región nor-occidental de Venezuela.

Pseudomyiasis is the term used for the accidental entrapment of swallowed fly maggots and/or eggs immediately passing through the digestive tract. We report a case of intestinal pseudomyasis caused by the larvae of the cosmopolitan drone fly Eristalis tenax (Diptera: Syrphidae) in a 39 year old woman, resident in a suburban sector from Coro city, Falcon state, Venezuela. The patient immediately noticed a living larva in her stool. Although patient referred eventually became colic, her physical examination was normal, with no mental disturbance. She was in a low socioeconomic level. This is the first report of an enteric pseudomyasis by E. tenax in the semiarid zone of Falcon state, in the northwestern region of Venezuela.

Mortality among Guarani Indians in Southeastern and Southern Brazil.

Worldwide, indigenous peoples display a high burden of disease, expressed by profound health inequalities in comparison to non-indigenous populations. This study describes mortality patterns among the Guarani in Southern and Southeastern Brazil, with a focus on health inequalities. The Guarani population structure is indicative of high birth and death rates, low median age and low life expectancy at birth. The crude mortality rate (crude MR = 5.0/1,000) was similar to the Brazilian national rate, but the under-five MR (44.5/1,000) and the infant mortality rate (29.6/1,000) were twice the corresponding MR in the South and Southeast of Brazil. The proportion of post-neonatal infant deaths was 83.3%, 2.4 times higher than general population. The proportions of ill-defined (15.8%) and preventable causes (51.6%) were high. The principal causes of death were respiratory (40.6%) and infectious and parasitic diseases (18.8%), suggesting precarious living conditions and deficient health services. There is a need for greater investment in primary care and interventions in social determinants of health in order to reduce the health inequalities.

Clinical issues in refugee healthcare: the Somali Bantu population.

With an estimated 803,500 refugees residing in the United States, many NPs will encounter patients who do not speak, read, or understand English. Many of these patients have challenging health issues such as parasitic diseases and chronic or acute diseases not commonly seen in the United States and NPs will need to be prepared for these challenges.

The "other diseases" of the Millennium Development Goals: rhetoric and reality of free drug distribution to cure the poor's parasites.

The sixth MDG aims 'to combat HIV/AIDS, TB, malaria and other diseases'. The residual category of 'other diseases' has become the focus of intense interest, partly because it has provided an opportunity to increase resources for the control of the mostly parasitic 'neglected tropical diseases' (NTDs). Intense lobbying has secured large amounts of funding from donors, as well as generous donations of medicines from the major drug companies. A massive programme is now underway to treat the parasites of the poor in Africa via integrated vertical interventions of mass drug administration in endemic areas. The approach has been hailed as remarkably effective, with claims that there is now a real prospect of complete control and, for some NTDs, even elimination. However, a closer look at evaluation and research data reveals that much less is known about what is being achieved than is suggested. Competition between implementing organisations is leading to potentially counterproductive exaggerations about treatment coverage. Detailed local-level research in Uganda and Tanzania shows that actual rates of drug take-up among target populations are often lower than is necessary to effectively control the diseases, and that methods of drug distribution may even lead to active resistance to treatment. If current trends are not corrected, declining rates of NTD infection will not be sustained. Much more rigorous and effective monitoring is essential.

[Imported and non-imported diseases in the immigrant population. A decade of experience from an infectious diseases unit]. / Enfermedades importadas y no importadas en la población inmigrante. Una década de experiencia desde una unidad de enfermedades infecciosas.

INTRODUCTION: Immigration is an inexorable process. Immigrants may suffer infectious diseases commonly seen in our environment, or those more exotic or more prevalent in their own environment. MATERIAL AND METHODS: A study was performed including all immigrants see in an Infectious Diseases Unit of a general hospital from June 2001 to May 2010. RESULTS: We studied 1,071 patients from Latin America (n=405, 37.8%), Northern Africa (n=281, 26.2%), Eastern Europe (n=186, 17.4%), sub-Saharan Africa (n=178, 16.6%), and Asia (21, 2.0%). Transmissible infectious diseases were the leading cause of consultation (53.8%), and they were more common among people coming from Northern Africa (61.6%) and Eastern Europe (69.4%) (P=.001). The second reason for consultation was for common infectious diseases (29%). Tropical infectious diseases were diagnosed in 16.4% of the patients, particularly from sub-Saharan Africa (36%), and Latin America (25.9%) (P<.001). The most common diagnoses were latent tuberculous infection (20.8%) [most common in those from Eastern Europe (27.4%) (P=.004)], respiratory tract infection (12.5%), sexually transmitted infections (10.6%) [most common in patients from Northern Africa (17.1%) (P=.004)], chronic hepatitis (10.4%) [most common in patients from Eastern Europe (26.3%) (P<.001) and sub-Saharan Africa (16.9%) (P=.004)], and active tuberculosis (8.7%) [most common in sub-Saharan Africa patients (15.7%) (P=.001)]. CONCLUSIONS: The spectrum of infectious diseases in the immigrant population in our area is broad, and includes a wide variety of tropical and communicable diseases, but also of common infections. While communicable diseases are the leading cause of consultation, common infections constitute an important part of health care activity.

Mortality among Guarani Indians in Southeastern and Southern Brazil / Mortalidade indígena Guarani no Sul e Sudeste do Brasil

Worldwide, indigenous peoples display a high burden of disease, expressed by profound health inequalities in comparison to non-indigenous populations.

Mundialmente, povos indígenas apresentam elevada carga de doença, expressa por profundas iniquidades em saúde na comparação com os não-indígenas. Neste estudo, descreve-se a mortalidade Guarani no Sul e Sudeste do Brasil, com foco nas iniquidades em saúde. A estrutura populacional Guarani expressa elevada natalidade, mortalidade precoce e baixa idade mediana e esperança de vida ao nascer. A taxa de mortalidade bruta (TM bruta = 5,0/1.000) se assemelha à nacional, mas a TM < 5 anos (44,5/1.000) e a taxa de mortalidade infantil (29,6/1.000) são duas vezes maiores que as TM correspondentes nas regiões Sul e Sudeste. A proporção de óbitos infantis pós-neonatais foi de 83,3 por cento, 2,4 vezes maior que a população geral. As proporções de causas mal definidas (15,8 por cento) e de evitáveis pelos serviços de saúde (51,6 por cento) foram elevadas. As principais causas de morte foram as respiratórias (40,6 por cento) e as infecciosas e parasitárias (18,8 por cento), sugerindo precárias condições de vida e de organização dos serviços de saúde. Há necessidade de maiores investimentos na atenção primária e em intervenções sobre os determinantes sociais da saúde, a fim de reduzir as iniquidades reveladas.

Blood lipids, infection, and inflammatory markers in the Tsimane of Bolivia.

OBJECTIVES: Little is known about blood cholesterol (blood-C) levels under conditions of infection and limited diet. This study examines blood-C and markers of infection and inflammation in the Tsimane of the Bolivian Amazon, indigenous forager farmers living in conditions that model preindustrial European populations by their short life expectancy, high load of infections and inflammation, and limited diets. METHODS: We use multivariate models to determine the relationships between lipid levels and markers of infection and inflammation. Adult Tsimane (N = 418, age 20-84) were characterized for blood lipids, cells, and inflammatory markers in relation to individual loads of parasites and village region. RESULTS: Most of the Tsimane (60%) carried at least one parasite species, averaging 1.3 species per person. Serum high-density lipoprotein cholesterol (HDL-C), total cholesterol (total-C), and low-density lipoprotein cholesterol (LDL-C) were below the U.S. norms and varied inversely with markers of infection and inflammation: C-reactive protein (CRP), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), immunoglobulin (Ig) E and eosinophil count. Although no relationship of parasite load to blood-C was found, there was an association between anemia and parasite prevalence. CONCLUSIONS: We conclude that the highly infected environment of the Tsimane is related to low levels of blood total-C, HDL-C, and LDL-C. This may suggest a potential reason why arterial disease is largely absent in the Tsimane.

Patterns of mortality in California Hmong, 1988-2002.

BACKGROUND: From mid-1980s to early 1990s, there were several studies evaluating a condition known as "nocturnal sudden death syndrome" among the healthy, young Hmong (immigrants from Laos) individuals who mysteriously died from unknown causes during the night. To date, very little has been reported on the mortality patterns in the Hmong. The purpose of the present study is to examine causes of death (COD) and compare age-adjusted mortality rates (AAMR) in the Hmong with those of non-Hispanic white (NHW) population in California, which may yield useful data for health prevention and planning purposes. METHODS: This study was based on 2,744 Hmong deaths occurred in California from 1988 to 2002. To calculate AAMR, Hmong population at risk of dying was derived by interpolating Hmong population counts from the 1990 and 2000 decennial censuses. For comparison, AAMR were calculated for both Hmong and NHW, and the statistical test, incidence rate ratio, was used to examine differences in relative mortality risk of each major COD between Hmong and NHW. RESULTS: AAMR are highest in neoplasm (184.0/100,000), circulatory (277.9/100,000) and respiratory (100.0/100,000) diseases for both Hmong and NHW. The AAMR for all COD during the entire study time period was 879.5/100,000 in males and 736.0/100,000 in females. AAMR for all other COD range from 4.9/100,000 to 67.2/100,000. Hmong experienced 1.3-1.9 times higher mortality rates for certain COD, compared to NHW. CONCLUSION: The interesting findings of this study are the differences in AAMR observed for lower ranking COD between Hmong and NHW. Hmong were found to be experiencing 1.3-1.9 times higher mortality rates for injuries and poisonings, digestive diseases, prenatal conditions, ENMID (endocrine, nutritional, metabolic, immunity disorders), infections and parasitic illnesses, and congenital anomalies when compared to NHW. However, while Hmong women were found to have statistically significantly higher mortality risk for injuries and poisonings (P-value < 0.05), ENMID (P-value < 0.05), and infections and parasitic ailments (P-value < 0.05) when compare to NHW women, Hmong men were observed to be at statistically significantly higher mortality risk for just infections and parasitic diseases (P-value < 0.05) when compared to NHW men.

Hábitos y creencias sobre parásitos y enfermedades parasitarias en habitantes de Santa Ana de los Guácaras, Corrientes, Argentina / Habits and beliefs about parasites and parasitic diseases among inhabitants of SantaAna de los Guácaras, Corrientes, Argentina

El objetivo del presente trabajo fue analizar las creencias populares que tienen los pobladores de la localidad de Santa Ana de los Guácaras, corrientes, Argentina sobre los parásitos y las enfermedades producidas por éstos y conocer los hábitos sanitarios en relación con las parasitosis. Se realizó un estudio de corte cualitativo. Se relevaron 39 hogares seleccionados de modo accidental en los que se aplicó una entrevista no estructurada al padre o madre de familia sobre los conocimientos acerca de los parásitos y las enfermedades que producen, síntomas y efectos, modos de prevención, transmisión, tratamiento y sobre hábitos sanitarios. El análisis de los datos se realizó conforme a la perspectiva de abordar el proceso de salud-enfermedad en función de las dimensiones propias de la esfera de la subjetividad. Para los pobladores la enfermedad parasitaria tiene una acepción restringida pues descartan las ectoparasitosis, las parasitosis infantiles son asumidas como naturales, lo que conduce a una actitud fatalista, que a su vez conlleva a no emprender estrategias de control. Se observa una inversión de las cadenas causales, hecho que provocan rupturas a la hora de relacionar todos los elementos vinculados en los ciclos de enfermedades parasitarias. Con este aporte se espera brindar herramientas para la comprensión sobre la permanencia de las parasitosis en Santa Ana de los Guácaras a fin de definir estrategias de previsión y control.

The purpose of the present work was to analyze the popular beliefs that people of Santa Ana de los Guácaras, Corrientes, Argentina, have on parasites and diseases they produce. Additionally, their health habits related to were investigated. A qualitative study was carried out. Thirty nine dwellings were randomly selected and a non structured interview was conducted with the father or mother of the family to investigate their knowledge on parasites and diseases that produce, symptoms and effects, methods of prevention, transmission, treatment and health habits. Data analysis was performed according to the perspective of addressing the health-disease process in accordance with the realm of their subjectivity. Results showed that parasitoses have a restricted meaning, since people do not take into account ectoparasites and parasitic diseases in children are assumed as natural, which leads to a fatalistic attitude, that in turn leads to not taking any control measures. There is a reversal of the causal chains, which cause breaks to relate all the elements linked to the cycles of parasitic diseases. This contribution is expected to provide tools for understanding the persistence of parasitic diseases in Santa Ana de los Guácaras and consequently, to define strategies for prevention and control.

[Health care utilization of intercountry adopted children. A Danish follow-up study]. / Internationalt adopterede--forbrug af sundhedsydelser. En dansk opfølgningsundersøgelse.

INTRODUCTION: Children adopted from developing countries have suffered from infectious diseases, malnutrition, growth and psychomotor retardation on arrival to adopting families. Aims were to investigate the degree of health care utilization among intercountry adoptees and to assess whether health care utilization was higher than for non-adoptees. MATERIALS AND METHODS: A historical follow-up study of a cohort of children intercountry adopted to the County of North Jutland in Denmark from 1995-1998 and a group of controls. Adoption was exposure and health care utilization was outcome. Data about hospitalization and selected ICD-10 diagnosis were ascertained from The Danish National Health Register and data about use of general practitioners (GPs) and specialists were ascertained from The National Health Insurance Service Registry. Relative risk (RR) of hospitalization and use of specialists was estimated. Average use of GPs was calculated. RESULTS: The risk of hospitalization and contact to specialists was 61% and 43% higher for adoptees compared to non-adoptees. Adoptees had a 10% increased average use of GPs the first year after arrival whereas there were no differences in the total average use of GPs. The risk of being discharged from hospital with a diagnosis within the ICD-10 diagnose group of congenital malformation and deformation was increased (RR: 3.0). CONCLUSION: Intercountry adopted children had an increased risk of health care utilization and an increased average use of health services. Further investigation is required in order to obtain information about the type of utilization.

Clinical status and parasitic infection in a Wichí Aboriginal community in Salta, Argentina.

In a study, carried out in 2000, of the clinical and parasitological status of a Wichi Aboriginal community living in the suburbs of Tartagal, northern Salta, Argentina, 154 individuals were screened for parasitic infections. Ninety-five faecal samples were also obtained from the same population. Ninety-three percent of the subjects were positive for 1 or more of the parasites investigated by direct test and 70.5% of them had parasitic superinfection. The most frequent helminths were Strongyloides stercoralis (50.5%) and hookworm (47.4%). We found low reinfection rates and a long reinfection period after treatment and provision of safe water and sanitation. Serum reactivity of these patients was analysed by enzyme-linked immunosorbent assay and indirect immunofluorescent assay and 22.1% of them had anti-Toxocara antibodies, 16.2% were positive for a complex antigen of Leishmania braziliensis, 29.9% were positive for a complex Trypanosoma cruzi antigen, and 17.5% were positive for a specific Trypanosoma cruzi antigen, Ag 163B6/cruzipain.

[Value of screening for intestinal and urinary parasites in non-resident permanent students in Tunisia]. / Intérêt du dépistage des parasitoses digestives et urinaires chez les étudiants non résidents permanents en Tunisie.

In order to fight digestive and urinary parasitoses, a national program of surveillance has been founded. The screening of these parasitoses among the non permanent resident students in Tunisia (ENRPTS) is one of the main actions of this program. Among 2560 ENRPTS tested in the laboratory of Parasitologie of Institut Pasteur of Tunis, between 1998 and 2002, 674 were infected by parasites, which represents a global prévalence of 26.3%. The intestinal protozoa constitute the majority of parasites identified (87.4%). Entamoeba histolytica has been isolated in 89 cases, essentially from students from tropical African countries. Urinary bilharziosis has been diagnosed in 25 cases. These results confirm the utility of the control of the ENRPTS. The precocious tracking permits to avoid the introduction and the dissemination of parasites already absent or rare in our country.
