Taking into consideration the increasing intercontinental tourist traffic we are in an increasing degree confronted with diseases which above all or exclusively acquired in warm countries. Besides the diseases which occur in our country they must find differential diagnostic consideration in disturbances of the health. On account of their frequency gastrointestinal disturbances they are essential for these travellers. On the basis of the following instances of diseases problems of the differential diagnosis and the evaluation of findings are shortly demonstrated: colon amoeboma; colon carcinoma; colon polyposis; ascaridasis; lambliasis; trichuriasis, affection with fasciola hepatica; affection with fasciolopsis buski; schistosomiasis intestinalis. It is referred to peculiarities in inhabitants of the tropics who transitorily live in our climatic zone.

In response to public concerns, 165 Meo Laotians had stools screened for intestinal parasites by the Illinois Department of Public Health. One hundred twenty-nine had at least one pathogenic parasite detected. Hookworm was detected most frequently, followed by Giardia lamblia, Trichuris trichiura, and Ascaris lumbricoides. Hookworm and overall infection were more frequent in persons 4 years of age and older, while giardiasis, ascariasis, and trichuriasis were most common in the 4- to 14-year age group. Most infections were helminthic and of no public health consequence in the United States. However, giardiasis was seven times as prevalent in refugee children as in the general US population, posing a potential public health risk in child-care settings.

When 239 (1982) and 361 (1991) five- and nine-year-old children in St. Kitts were assessed for the presence of parasitic infections, there were significant reductions in the prevalence of trichuriasis from 83% to 58%, of ascariasis from 24% to 8.6% and of giardiasis from 15% to 9.4%. Anthelminthic use, which appeared to be the most important responsible intervention tool, remained roughly at the same level at 59-51%. However, the types of anthelminthics used changed over the period. Piperazine citrate, which was used by 66% in 1982, only had 35% usage in 1991. Albendazole which was not used at all in 1982 was taken by 32% of the children in 1991 and at the same time use of laevo-tetramisole increased by 20% from 14%. Suggestions are made for an island-wide mass intervention programme to manage parasitic infections.

Many different infections with protozoan and helminthic parasites are common global health problems. Several protozoa are responsible for opportunistic infections in patients with AIDS. The newly developed drug, albendazole, has a strong activity against many nematode and cestode parasites. In the case of echinococcosis, it reduces the viability of protoscolices and cysts. Its hepatic metabolite, albendazole sulfoxide, is active against the larval cestodes. In the case of neurocysticercosis, administration of either the standard treatment, praziquantel, or the newly developed drug, albendazole, reduces or eliminates tapeworm cysts in 80-90% of patients. Patients with numerous cysts and those in whom neurologic symptoms or intracranial hypertension develops after therapy against cysticerci should receive adjunctive therapy with dexamethasone. Mass chemotherapy with single doses of albendazole or the older drug, mebendazole, is feasible for school-age children to treat the soil-transmitted helminthiases (ascariasis, hook-worm infection, and trichuriasis). The newly developed drug, ivermectin, is more effective against chronic strongyloidiasis than albendazole. It has been used most extensively against river blindness. It greatly reduces the number of microfilariae in the skin and eyes but has no effect on sclerosing keratitis or chorioretinitis. Both drugs are available in the US on a compassionate-use basis from their manufacturers. Field trials show that ivermectin is also effective against lymphatic filariasis and Mansonella ozzardi. Praziquantel is effective against many trematode and cestode infections. It is the drug of choice for schistosomiasis. Albendazole was effective against giardiasis in children in Bangladesh but ineffective in adult travelers returning from tropical areas. It appears to effect symptomatic improvement of intestinal microsporidial infections in patients with AIDS. The newly developed drug, fumagillin, can ameliorate ocular microsporidiosis. The newly developed drug, paromycin, treats cryptosporidiosis. Trimethoprim-sulfamethoxazole treats cyclosporiasis and isosporiasis.

A survey was carried out among the rural and urban settlers and two tribal groups viz. Nicobarese and Onges, of Andaman and Nicobar islands. The survey covered preschool school aged children and adults. Out of the total 1,384 stool samples examined, 652 (47.1%) showed ova or cysts of one or more intestinal parasites. Among the preschool children, Nicobarese showed the highest overall prevalence rate (80.5%) followed by urban (46.7%) and rural (38.6%) preschool children. Ascaris lumbricoides was the commonest form of parasite encountered in all the groups of preschool children, followed by Trichuris trichura. While ascariasis and trichuriasis were more common among the urban children than in rural children, giardiasis was more common among the rural preschool children. The school age children among rural settlers showed an overall prevalence rate of 61.1% which was significantly higher than that among the rural preschool children. Among the school age children also, ascariasis was the commonest form of parasitosis followed by trichuriasis. The Nicobarese and Onge adults showed significantly higher overall prevalence rates (72.2%) and 71.1% vs 48.6%) compared to rural adults. In all the groups studied ascariasis was the commonest form of parasitosis except in Onges among whom trichuriasis and giardiasis were more common than ascariasis. Change in prevalence rates over age was studied among the rural settlers. While ascariasis and trichuriasis showed peak prevalence rates in school age children prevalence of giardiasis declined with increase in age from a peak in the preschool age group and prevalence rates of hook worm infestation continued increasing beyond school age.

The study examined the incidence and prevalence of parasitic diseases among military personnel of the United Nations Interim Force in Lebanon (UNIFIL) and local civilian population. Additionally, the authors investigated the potential risk factors, including environmental conditions, influencing the incidence of infectious diseases. Epidemiological analysis was conducted based on the medial records of patients treated in the Internal and Surgical Ward of the UNIFIL Hospital from 1993 to 2000. The patients with parasitic diseases accounted for 3.78% of all patients hospitalized during the analyzed period. The most frequent infectious diseases treated during that time were trichuriasis, ancylostomiasis, giardiasis and ascariasis.

This study aims to determine the prevalence of protein-energy malnutrition and its association with soil-transmitted helminthiases in Orang Asli (Aborigine) children in Selangor, Malaysia. The results obtained from 368 children aged 2-15 years showed that the overall prevalence of mild and significant underweight was 32.1% and 56.5% respectively. The prevalence of mild stunting was 25.6% while another 61.3% had significant stunting. The overall prevalence of mild and significant wasting was 39.0% and 19.5% respectively. The overall prevalence of ascariasis, trichuriasis and hookworm infection were 61.9%, 98.2% and 37.0% respectively and of these 18.9%, 23.5% and 2.5% of the children had severe infection of the respective helminthes. The overall prevalence of giardiasis was 24.9%. The present study vividly shows that stunting and underweight are highly prevalent among Orang Asli children and therefore of concern in this community. In this population intestinal parasitic infections, especially severe trichuriasis and giardiasis, were identified as the main predictors of stunting and wasting respectively, in addition to age between 2 to 6 years.

Infection caused by intestinal parasites is still a common health problem in a poor-hygiene population especially for children in developing countries. A cross-sectional study was conducted among 781 Karen students (age: 3 to 19, males: 325, females: 456) to determine the current status of intestinal parasitic infections in a mountainous area in the North of Thailand. The study was drawn from three schools in the Doi Inthanon region, in Mae Chame district of Chiang Mai province, from December 2002 to June 2003. The techniques used for the diagnosis were: stool concentration by using the 'formalin-ether' technique and perianal region examination by using the 'Scotch-tape' technique. The average rate of intestinal parasites for the group tested using the stool concentration technique was 42.06% (male: 46.87%, females: 38.82%); and 22.66% (males: 28.92%, females: 18.20%) when using the Scotch-tape technique.Among helminth-infected individuals, enterobiasis was found at the highest prevalence (15.49%). Other common infections were ascariasis (9.78%), trichuriasis (5.90%) and hookworm infection (2.20%). Strongyloildiasis was found only in 0.92%. For protozoa infection, the major cause is the non-pathogenic species "Entamoeba coli" (27.68%). The other non-pathogenic protozoa (Endolimax nana, Chilomastix meslini and Iodamoeba butschlii) had a low prevalence from ranged 0.18%-4.79%. The prevalence of pathogenic Giardia lamblia infection was 2.21%. Entamoeba histolytica infection was found in only one case. Based on the two techniques used, the results from the Scotch-tape provided a higher sensitivity for the detection of Taenia spp. and Enterobius vermicularis eggs. Drug treatment was given to all the infected students. School-based health education should be implemented in order to prevent and control the infections.

There is a considerable amount of speculations concerning the presence of symptoms in various parasitic infections. The aim of the present study was to determine the prevalence of different parasitic infections among children in day care centers (DCCs), and to establish the relation of such infections to gastrointestinal symptoms. A total of 623 stool samples were collected from 700 preschool children aged 2-5 years who attended 3 DCCs of different social classes in Alexandria. These samples were tested for parasitic infection by the conventional microscopy. Parents were interviewed as regards the gastrointestinal symptoms frequently suffered from by their children included in the sample during the 3 months period preceding the interview. The prevalence rate of parasitic infection was 56.0%. Giardiasis was the commonest infection (34.7%), followed by Ascariasis (24.4%) and Trichuriasis (4.6%). Boys showed a significantly higher prevalence than girls (58.3% vs. 52.9%, p<0.01). Social children were more infected with G. lamblia than unsocial ones (39.6% vs. 22.1%, p<0.01). Vomiting was strongly associated with G. lamblia infection (OR=7.1, p<0.01), diarrhea with multiple infections (OR=48.2, p<0.01), while abdominal pain was not significantly associated with any of these infections. The high prevalence of Giardiasis in DCCs emphasizes the need for increased surveillance for G. lamblia as a cause of vomiting in children, especially among active and social boys. Routine and periodic administration of a protozoan treatment to such children is recommended.
