We examined fecal specimens of Japanese residents in developing countries in order to know the prevalence of intestinal parasites in the group. One fecal specimen was collected from each 981 (in 1995) and 1275 (in 1996) Japanese living in Asia, the Middle East, Europe, Africa and Latin America. The specimens were fixed with 10% formalin in each area, and were examined in Japan by concentration method (formalin-ether sedimentation) to find protozoan cysts or helminth eggs. The infection rate of intestinal parasites was 3.0% in 1995 and 2.4% in 1996. The rate was high in Africa (1995: 5.7%, 1996: 4.7%) and Asia (1995: 3.8%, 1996: 3.0%). Regarding to the species of the parasites, Giardia lamblia (17 cases), Trichuris trichiura (14) and Ascaris lumbricoides (11) were detected frequently. Additionally, 7 cases of Heterophyes heterophyes infection were found in Asia and the Middle East. The infection rate was higher in adults than that in children, and a positive relationship between the infection rate and duration of stay was observed. Among the Japanese infected with intestinal parasites, abdominal symptoms such as diarrhea or abdominal pain were common (36.8%). It is also noteworthy that 28.1% of the Japanese infected had a history of gastric diseases such as gastric ulcer. Although the infection rate of intestinal parasites among Japanese residents in developing countries was low, compared to that of the natives in the countries, the rate is still higher than that in Japanese living in the home country. It is necessary to continue preventive measures such as health education in order to eradicate intestinal parasitic infections from this group.

Human strongyloidiasis is an important health problem in the southeast region of Peruvian Amazon, due to its prevalence and long term morbidity. An epidemiological study was conducted in the Peruvian Amazon area of Puerto Maldonado to determine the prevalence of strongyloidiasis in the population. Stool samples were collected from 1,133 patients at the outpatient department of our clinic. Strongyloidiasis affected 221 examined patients (20%). Prevalence was highest in males, mostly in children and elderly men. People living in urban and marginal urban areas, those coming from outside the region, and Andean people, showed the highest prevalences. Pre-school children were more likely to be parasitized than older children. The most common symptoms were diarrhea (55%), abdominal pain (32%) and cough (53%). One in 7 (13%) affected patients presented with moderate or severe symptoms, including life-threatening complications. Other intestinal parasites were found frequently in patients diagnosed with strongyloidiasis. Improved human waste disposal services are considered to be the main requirement to reduce the high prevalence of this disease.

A single dose of Tetramisole, 2.5 mg/kg body weight, was given to the infected cases of intestinal parasites. The number of cases were: Ascaris lumbriocides 96, hookworm 16, Trichostrongylus orientalis 10, Trichocephalus trichiurus 114 and Clonorchis sinensis 19. No dietary restriction before and after the administration of Tetramisole was required. 1. In Ascaris infection the egg negative conversion rate and the egg reduction rate were 92.7 per cent and 99.5 per cent, respectively. 2. In Trichostrongylus orientalis infections, 9 out of 10 cases were resulted egg negative after the single dose of Tetramisole, and hookworm, 12 out of 16 administered showed egg negative. However, there were no appreciable effectiveness to the cases of Trichocephalus trichiurus and Clonorchis sinensis. 3. Mild and transient side effects were noted in 75 cases (54.5%) out of 140 cases. The main symptoms were dizziness (25.5%), anorexia (25.5%), abdominal pain (18.6%), diarrhea (16.6%), headache (15.2%), nausea (14.4%) and fever (11.0%). From the above results, it is anticipated that Tetramisole is an effective anthelminthic for elimination of Ascaris, Trichostrongylus and hookworm.

Intestinal parasitic infections are major causes of childhood diseases in rural regions. The significant causes of this problem are the insufficient resources to improve the infrastructure in these regions and inadequate health services in both the diagnosis and treatment of diseases. The aim of this study was to assess the association between intestinal parasitic infections and clinical symptoms of infected children. Cellophane tape and stool samples of 100 children, aged between 7-10 years, from two villages of Manisa city, were examined for intestinal parasites and their symptoms were recorded. Although some symptoms, such as abdominal pain, anorexia and fatigue were found to be common in infected children, no significant relationship was found between symptoms and intestinal parasitic infections.

The most frequent symptom of taeniasis is the discharge of proglottids (93.7%). Gravid proglottids which do not have uterine pores are damaged when they exit the anus by their movement. Because of this damage most of the eggs contaminate the perianal tract. The cellophane tape technique that is used for getting perineum material is also a convenient technique for diagnosis of taeniasis. A 36 year-old woman was admitted to our parasitology clinic complaining of a watering mouth for one year, of abdominal pain, and of loss of appetite for 6 months, and who had discharged proglottids from time to time. She had been eating raw meat since her childhood and had had treatment for taeniasis fifteen years ago. She has also been under treatment for obsessive and compulsive neurosis and depression for two years and complained of constipation that was the side effect of the drug clomipramine HCL. She was given treatment with niclosamide and purgative treatment. The result of the treatment was incomplete because the patient refused to use the purgative. She was called for follow up controls two weeks and six months after treatment and after six months did not have any evidence of infection in her stools. When she was asked, the patient said that she did not need to use the drugs for the treatment of obsessive and compulsive neurosis and depression any more since her symptoms had decreased. According to various authorities, taeniasis is thought to be the cause of psychiatric symptoms due to its neural and psychological effects. These claims have been confirmed in our case because of her psychiatric symptoms decreased after the taeniasis treatment. Thus, the view that there is a relationship between intestinal parasites and psychiatric disease has been strengthened.

The prevalence of pathogenic intestinal parasites among preschool children in Al-Medina district, Saudi Arabia, was determined through a randomized multistage sampling of 8000 preschool children. Duplicate specimens from each child were examined using a simple sedimentation technique. The overall prevalence of intestinal parasites among children screened was 18.4%. The most common parasite isolated was Giardia lamblia (14.5%). This was followed by Entamoeba histolytica (2.7%), Enterobius vermicularis (1.4%), Ascaris lumbricoides (1.0%) and others. Out of the 1462 children positive for parasites, 183 (12.5%) had mixed parasitic infections. Prevalence among preschool children was highly associateed with older age, rural residence, non-municipal water supply, inadequate latrine type, low level of parental education, abdominal pain, and diarrhea.

The present study was conducted to determine the prevalence and clinical features of dientamoebiasis in patients presumed to be infected with intestinal parasites. A total of 168 patients were examined for D. fragilis using microscopy (after Wheatley's trichrome staining) and culture (using modified Boeck and Drbohlav's medium). D. fragilis trophozoites were detected in 15 samples (8.9%) examined using trichrome staining and in 50 samples (29.8%) by culture method. Other enteric parasites were common in the study population as 48.8% of patients (82/168) were found harboring intestinal parasites. Blastocystis hominis was the most common, identified in 33.3% (56/168) of the samples. Giardia lamblia was detected in 17.9% (30/168) and E. histolytica/E. dispar in 11.9% (20/168). The symptoms most frequently encountered were diarrhea, abdominal pain and weight loss and fatigue. Diarrhea and abdominal pain were significantly more frequent in patients with dientamoebiasis compared to non pathogenic cases (P < 0.05). Diarrhea was 38.5% of patients infected with D. fragilis compared to 50% of patients infected with G. lamblia, while abdominal pain was encountered with D. fragilis in 41% compared to 33.3% with G. lamblia. These differences were insignificant (P > 0.05).

We investigated the frequency of the presence of intestinal parasites and the factors affecting this frequency in an elementary school. We tried to discover whether there was a relationship between the presence of intestinal parasites and sanitary habits such as hand washing, toilet flushing, and use of human manure, cleanness of drinking water and also the educational level of the parents. A total of 114 students participated in this study. Samples were collected using cellophane tape preparations. All fecal samples were examined using native-Lugol and the trichrome staining. Fecal samples taken from 111 students were examined, 37 (33.3%) of them contained one or more parasites. The parasites encountered most often were E. vermicularis 16 (14.4%), G. intestinalis 10 (9.0%), and E. coli 4 (3.6%). In addition children carrying intestinal parasites complained about abdominal pain (22 students), itchy nose and the accumulation of saliva around their mouths (9 students). Although no meaningful relationship was found between the use of human manure/toilet flushing with the presence of parasites, the educational level of the parents, cleanness of the drinking water and hand washing habits seem to be related to the presence of parasites. Our findings indicate that elementary students should be educated in the prevention of parasitic infections.

The epidemiological pattern of cryptosporidiosis and other intestinal parasites were studied among 3 orphanages in Sana'a City. A total of 292 orphans (225 males & 67 females), aged 4-20 years old were recruited. A questionnaire of demographic information, health status and other relevant information was filled out for each one. Fresh stool specimens were processed by wet mount preparation, formalin-ether concentration and MZL stain. Among 292 orphans, the overall parasitic rate was 62.7%. C. parvum showed highest prevalence (24%) followed by G. lamblia (16.8%), E. histolytica /E.dispar (13%), and then E. coli (18.5%). Hymenolepis nana was in 7.2% of children but only 3 cases of Ascaris lumbricoides. The risk of C. parvum was significantly higher in children < or = 10 years of age compared to older ones (OR = 3.86). The risk of other parasites did not differ significantly with orphans' age. Males showed 2.634 risk of C. parvum and 1.657 risk of G. lamblia compared to females with statistically significant difference. Bad personal hygiene was associated with higher risk of cryptosporidiosis (OR = 2.634, CI = 1.483-4.677) but the risk of other parasites was not significant. Diarrhea and abdominal pain were recorded in the three orphans, but without significance associated with parasites, either overall or for individual species but, A. lumbricoides was detected in 3 diarrheic children.

Ascariasis is the most common helminthic infection in developing countries. It may cause chronic abdominal pain, tenderness and bloating. Our aim is to report a case of acute episodic abdominal pain and pancreatitis associated with ascariasis. We report a 59-year-old female patient who was admitted for acute abdominal pain, having had several previous similar events before one of them was diagnosed as acute idiopathic pancreatitis. On admission, her physical exam was normal. Laboratory results showed hemoglobin 12.2 g/dL, white blood cell count 11 900 cells/mm(3), eosinophils 420 cells/mm(3), serum amylase 84 IU/mL, lipase 22 IU/mL and normal liver function tests. Abdominal ultrasound and a plain abdominal X-ray were also normal. An upper endoscopy showed round white worms in the duodenum and the stomach, some of them with bile in their intestines. The intestinal parasites were diagnosed as Ascaris lumbricoides, and the patient was started on albendazole, with full recovery within a week. We believe that ascariasis should be considered in patients with recurrent abdominal pain and idiopathic pancreatitis.
