Forty-six Chinese patients with primary gastrointestinal lymphoma were analyzed. The most common presentations were with abdominal pain, bleeding or a palpable mass. Only one case resembled the pattern of the so-called "Mediterranean lymphoma." The most common primary sites were the stomach and the ileum. One case of colonic lymphoma was associated with schistosomiasis but was probably not etiologically related. The pattern of primary gastrointestinal lymphoma in Chinese corresponds in general to the pattern observed in western countries.

A survey for schistosomiasis in a village in the Gezira area of the Sudan in 1973 showed that there has probably been a great increase in the incidence of S. mansoni infection in the last 25 years. Severe morbidity was uncommon in this sample but overt infection was associated with the symptoms of bloody diarrhoea, tiredness, and possibly abdominal pain, and with a reduced level of haemoglobin. Hepatosplenomegaly was common and schistosomiasis is considered to have contributed to this, although hyperendemic malaria must also have been important in its causation.

450 patients in Riyadh, Saudi Arabia, complaining of chronic abdominal pain and, coming from different countries endemic for schistosomiasis, were examined endoscopically using fibre-optic colono- or sigmoidoscopes, and rectal biopsies were examined for Schistosoma mansoni ova. After a preliminary study showed that more than 6 biopsies did not increase the positivity rate, 6 biopsies were taken from the rectum and examined by transparency technique. 280 were positive for S. mansoni, 9 of them having in addition S. haematobium. 4 patients had polyps in the sigmoid colon and rectum. When these positive cases were examined using duplicate 50 mg Kato smears, only 160 (57.1%) were positive. There was a highly positive correlation between the intensity of infection as graded by the 2 techniques. We recommend examination of 6 rectal biopsies using fibre-optic sigmoidoscopy when available in small communities with a patchy distribution of schistosomiasis like Saudi Arabia. The method could also be used to exclude schistosomiasis in persons who have moved from rural to urban or non-endemic areas and are unlikely to be re-exposed to infection.

A 13-year-old girl presented with fever, night sweat, weight loss, abdominal pain, haematuria and hepatosplenomegaly. Urinalysis revealed many Schistosoma haematobium ova, but rectal snip examination was negative for schistosomal ova. X-ray and CT scan of the chest revealed enlargement of the anterior, superior, mediastinal and left suprahilar lymph node with an adjacent left pulmonary parenchymal opacity and small peripheral lesions on the right side. A bone marrow aspiration and biopsy was normal. The patient was treated with Praziquantel for her urinary schistosomiasis. Because of her clinical and radiological chest findings, the possibilities of lymphoma and tuberculosis were considered. Therefore, she underwent a thoracotomy and biopsy of her thoracic lesions. The histopathology revealed pulmonary granulomas surrounding schistosoma ova with reactive mediastinal lymph adenitis.

Infections by adult cestodes are widely distributed in the world, and induced digestive and general disturbances. In this study, 40 patients with Taenia saginata and 15 with Hymenolepis nana were treated by one single oral dose of Praziquantel, at the dosage of 10 mg/kg/day and 20 mg/kg/day respectively. As side effects, no biological disturbances occurred, but 6 patients complained of abdominal pain and diarrhea. The efficiency was complete. Praziquantel, a wide spectrum anti-helminthic day drug, used in schistosomiasis, fascioliasis, cysticercosis, is the best treatment of adult cestodes.

Periportal contrast enhancement relative to adjacent liver and portal blood has been reported on CT scans in cases of schistosomiasis and hepatic Kaposi sarcoma in AIDS patients. We observed this phenomenon in 10 (8%) of 130 consecutive, contrast-enhanced, nondynamic CT examinations of the abdomen. Thus, the occurrence is more common and less specific than previously reported. Seven of the 10 patients in our series were receiving chemotherapy for malignant disease, and three had abdominal pain with no definitive diagnosis. In four of the 10 patients, corresponding areas of periportal low attenuation or radiolucency were observed on initial dynamically enhanced scans. Periportal enhancement may be related to late diffusion of contrast material into periportal areas that were initially radiolucent. Such diffusion may occur because of endothelial insult. Periportal contrast enhancement appears to be a nonspecific finding on nondynamic contrast-enhanced CT scans of the abdomen. Periportal enhancement is important to recognize because it can mimic the appearance of portal vein thrombosis and may also be used to differentiate intrahepatic biliary dilatation from periportal radiolucency.

The clinicopathological features of schistosomiasis of the appendix are discussed, based on the clinical presentation, operative findings and morphological changes in the specimens of patients seen in Ibadan between 1980 and 1989. Schistosoma haematobium was implicated as the causal agent of a granulomatous inflammatory reaction with eosinophilia and fibrosis. Intramuscular oviposition was associated with frank acute appendicitis, and serosal involvement resulted in peritoneal adhesions, with ileoileal intussusception in one patient. The actual role of schistosomal infestation as a contributory factor in appendicitis is still open to debate, but the diagnosis must be entertained in patients in the tropics with features of acute appendicitis or recurrent abdominal pain.

This study evaluates 216 patients with schistosomal colonic disease, diagnosed by endoscopic biopsies at the Armed Forces Hospital, Riyadh. The colonoscopic appearance was suggestive of schistosomiasis in 98 of these patients (45.37%), Schistosoma mansoni ova in stool was detected in only 24 of these 216 patients (11.11%). The most common histopathological finding in colonic biopsies of these patients was Schistosoma mansoni ova in the colonic mucosa with no or mild inflammatory cells infiltrates. These findings correlate with the endoscopic appearances in most patients. The most common symptoms were abdominal pain or distention in 84 patients (38.88%). Sixty five patients (30.09%) had hepatosplenic schistosomiasis. Eight patients had schistosomal polyps and two patients had colonic malignancy in which no association between their malignancy and Schistosoma mansoni infection was established. After antischistosomal treatment follow up, sigmoidoscopy was normal in 28 patients who previously had abnormal endoscopic appearances. Colonoscopic examination is valuable in colonic schistosomiasis as it can show characteristic colonic lesions and colonic biopsies are diagnostic and correlates with histological findings.

Morbidity due to infection with Schistosoma mansoni was investigated in a recently discovered highland focus around Lake Cohoha, Burundi. The distribution of the infection was very focal and morbidity patterns in populations from an endemic area A (prevalence 38%, mean egg load of positive subjects 231 eggs per gram [epg]), a less affected area B (16%, 90 epg) and a virtually non-endemic area C (5%, 45 epg), were compared; apart from schistosomiasis, the profiles of these populations were highly similar. The overall frequencies of diarrhoea were 36%, 25%, and 19%, respectively; of abdominal pain 86%, 78%, and 83%; of fatigue 7%, 2%, and 1%; of left lobe hepatomegaly 30%, 18%, and 9%; of right lobe hepatomegaly 18%, 10%, and 5%; of splenomegaly 18%, 10%, and 7%. Organomegaly was generally mild, even in area A. Within area A, the association between the presence of infection and diarrhoea, fatigue, hepatomegaly and splenomegaly was significant, but far less impressive than the results of the community-based comparison with areas B and C. The correlation with intensity was limited to an increased prevalence of diarrhoea and fatigue in the highest egg count group, and a more gradual increase (varying with age) in hepatomegaly and splenomegaly. The data are compared to other morbidity studies in subsaharan Africa, in particular one in the nearby Rusizi Plain. The lesser impact of malaria, the higher egg loads, the recent establishment of the focus and possibly parasite strain differences may account for the more apparent and more important schistosomiasis morbidity in the Cohoha focus.(ABSTRACT TRUNCATED AT 250 WORDS)

A 42-year-old American male researcher contracted schistosomiasis from environmental sources in the course of his observations on human behavior in Upper Egypt. After a long asymptomatic period, he developed various symptoms and Schistosoma haematobium was found in a urine examination. After treatment with Metrifonate, urine examination became negative. However, abdominal pain persisted and most diagnostic tests were negative. Colonoscopic examination and biopsy of the mucosa revealed schistosomiasis. Treatment with Praziquantel was thoroughly effective in clearing the persistent Schistosoma haematobium infection. It is necessary to maintain a high index of suspicion in cases of potential schistosomiasis. The availability of nontoxic treatment is discussed.
