A cohort analysis was performed in Ndombo, Senegal, a community of about 4000, in the epicenter of the schistosomiasis outbreak. Four randomly selected cohorts of +or- 400 subjects were surveyed. Each cohort was examined parasitologically, clinically, and serologically (circulating antigen and antibody profiles); treated with praziquantel 40 mg/kg; and followed up at 6-12 weeks and at 1 and 2 years after treatment. The first cohort numbered 422 individuals, of which 91% had positive egg counts, with a mean egg count of 663 eggs per gram feces (epg). Quantitative egg counts in those aged 10-14 were 1409 epg and then declined to 632 epg in the age group 20-29 and to 266 epg in the age group over 40. In cohorts 2 and 3, examined in the spring and autumn, egg counts were substantially lower, particularly in adults, as compared with cohorts 1 and 4, which were both examined in the summer season. 94% of the subjects were positive in the serum circulating anodic antigen (CAA) ELISA, 83% in the serum CAA ELISA, and 95% in the urine circulating cathodic antigen (CCA) ELISA; CAA in urine was less sensitive, and was negative in half of the urine samples. Positivity rates for all assays increased with rising egg counts, and circulating antigen concentrations in both serum and urine correlated well with egg counts. IgE showed a significant increase with age, while IgG4 peaked in the age groups 10-15 and/or 15-19 years. A strong correlation between IgG, IgGl, and IgG4 against both crude antigens with pretreatment egg load was observed. Of the subjects in the first cohort, 61% reported abdominal pain, 33% diarrhea; only 16% showed mild hepatomegaly and only a few children had mild splenomegaly. In the first cohort, 82% of 298 reexamined subjects were still positive for S. mansoni 12 weeks after treatment with praziquantel 40 mg/kg. One year after treatment, cohort 1 showed mean egg counts in children (5-19 years) at 358 epg as compared with 1188 epg pretreatment.

An eleven-year-old male was diagnosed with multiple splenic abscesses due to brucella. He was treated only with antibiotics. Although splenic abscess is very rare in childhood, in febrile patients with upper quadrant abdominal pain, tenderness and splenomegaly, splenic abscess should be suspected especially in epidemic regions. Diagnosis can be confirmed by ultrasonography and computerized tomography.

A 25-year-old man with a 1 year history of episodic abdominal pain presented with splenomegaly, eosinophilic ascites and peripheral eosinophilia. Full-thickness biopsies from his gastrointestinal tract revealed intense eosinophilic infiltration involving both muscular and serosal layers and extending from his stomach to his ileum. When given oral steroids, the patient's condition improved and he was discharged without symptoms. Eighteen months later, he remains asymptomatic and without recurrence of ascites or splenomegaly. This report adds to the scarce data on extraintestinal involvement in eosinophilic gastroenteritis. Special attention is drawn to the differential diagnosis of eosinophilic ascites and to the optimal approach to its management.

An ectopic, so-called wandering spleen is an uncommon occurrence. We present the case of a young woman who presented with abdominal pain and was found to have an enlarged spleen, located in the lower abdomen and pelvis. The possibility of lymphoma was entertained because of concomitant findings of thrombocytopenia and a possible mesenteric mass. The mass was subsequently found at laparotomy to be the tail of the malpositioned pancreas, and the thrombocytopenia resolved with splenectomy. Review of the literature indicates that lymphoma is an uncommon finding in wandering spleens, that wandering spleens are enlarged in most cases, and that thrombocytopenia, while uncommon, can be seen, in particular when associated with torsion of an elongated splenic pedicle.

Lymphomas of the marginal spleen zone are an entity recently considered as separate by the International Lymphoma Study Group. There are B-cell non Hodgkin's lymphomas (NHL) of low grade malignancy with a characteristic phenotype that allows to differentiate from mantle lymphomas and other B-cell lymphoproliferative syndromes. The case of a 69-year-old female patient admitted for abdominal pain due to large splenomegaly is reported. Pancytopenia and the presence of atypical large-sized lymphocytes with extensive cytoplasm and a rounded nucleus with indentations, reticulated appearing chromatin and one or several nucleoli were of note in the hemogram. Microscopic examination of the bone marrow demonstrated moderate-degree lymphocytary infiltration with grade I reticulin fibrosis. Laparotomy with splenectomy was performed. White pulp invasion with multifocal infiltration of the red pulp by lymphocytes of the same characteristics as those observed in the peripheral blood and bone marrow were observed on microscopic bone marrow examination. Immunophenotypic study of these lymphocytes was positive for CD19, CD20 and CD22 while being negative for CD5, CD10, CD23, CD25, CD11c and FMC7, the phenotype belonging to the lymphocytes of marginal spleen zone. Following splenectomy the patient recovered hemoperipheral counts and did not undergo additional treatment. The patient died due to septic shock of respiratory origin 4 months later. The clinical, morphologic and immunophenotypic features of marginal spleen zone lymphomas are reported with emphasis on the differences with other B-cell non Hodgkin's lymphomas of low malignancy.

Lately, myeloprolipherative disorders are frequently reported as causes of portal vein thrombosis, probably due to the early detection of latent cases of this condition. We report two patients with portal vein thrombosis that presented with abdominal pain, nausea, vomiting and clinical consequences of portal hypertension such as variceal hemorrhage, splenomegaly and ascites. Diagnosis was made by a CAT scan in one patient and doppler ultrasound in the other. Both patients had high platelet counts and an essential thrombocytosis in the bone marrow.

Several authors assumed that spleen was resistant to neoplastic dissemination because of spleen metastasis are rare in relation to the incidence of metastasis in other parenchymatous organs. We report a clinical case of a symptomatic solitary spleen metastasis in cystic-looking bladder cancer; afterwards we'll examine real incidence of secondary splenic injury. In autopsy studies, the incidence of splenic metastatic spread is in contrast with the rarity of clinical manifestations of solitary metastasis. The case reported is really uncommon: a voluminous single metastasis, cystic-looking, with splenomegaly, abdominal pain and rapid onset. In the presence of a high malignancy primitive tumor, the evaluation of the effective utility of the surgical treatment carried out is premature, because of the relatively short follow-up. On the other hand, the painful symptomatology, the risk of disruption in peritoneal cavity, the impossibility to make inquiries about the nature of the cystic mass, imposed, in our opinion, a surgical treatment.

During the summer of 1980, acute Manson's Schistosomiasis occurred in 28 pediatric patients, swimming in two ponds with no watershed connections between them, in the rural area of Juncos and Cidra, Puerto Rico. Clinical and immunological events were studied and Oxamniquine (Vansil, Pfizer) was administered to all of them and followed closely for 3 years. Fever and general malaise recorded in 93% of the patients, diarrhea and abdominal pain in 68% and urticaria or facial edema in 64%. Hepato and/or splenomegaly was recorded in 71% of them. Twenty seven of the patients had evidence of immunoserological activity against adult schistosomal antigens (GASP and PSAP). Two patients had intense immunologic activity, even before the recovering of fresh Schistosoma mansoni eggs in their stool. This was a response to GASP and PSAP antigens. When they started passing fresh eggs of schistosoma and COP (Circumoval Precipitation Test) turned positive, their clinical status worsened and antibodies to GASP antigen increased two fold. The oviposition phase elicited a strong antibody and immunological reaction with significant eosinophilia and cross reaction was observed between adult schistosomal and egg shell antigens. Severe clinical manifestations were seen in spite of low egg excretion. Oxamniquine was effective in obtaining a coprological cure and in altering the immunologic response as compared with other untreated groups in literature.

One thousand six hundred and ninety-five inhabitants of 3 rural villages on Ukerewe Island, Lake Victoria, Tanzania, were examined by clinical, parasitological, ultrasonographic and--in part--serological means to evaluate Schistosoma (S.) mansoni-related morbidity on a community level. Villagers frequently complained of typical colitis symptoms (abdominal pain 80.1%, bloody stools 43.1%, diarrhoea 35.1%); haematemesis, on the other hand, was rare (and reports doubtful in most cases). 16.9% of the population had been given praziquantel previously. Overall S. mansoni prevalence was 86.3%, with a median egg output of 176 eggs per gram (e.p.g.) and maximum output of 17,984 e.p.g. Children and adolescents were infected more severely than adults, men more severely than women. Pretreated individuals excreted significantly fewer ova (median 124 vs 192e.p.g., P < 0.001). Hepatomegaly (determined by ultrasonography) was present in 35%, splenomegaly in 80%. Organomegaly was significantly related to egg output. Pretreated persons had lower rates of splenomegaly and left lobe hepatomegaly. Low-degree periportal fibrosis was common, while severe grades of fibrosis (MANAGIL score II and III) were present in about 6%. About 10% had other abnormalities on liver sonography (irregular parenchymal texture and/or shape); these person passed significantly more S. mansoni ova than others. Clear sonographic signs of portal hypertension were seen in 2.1%. Serum procollagen-IV-peptide and gamma-glutamyl-transferase levels were increased in persons with severe periportal fibrosis, irregular liver texture of portofugal collateral vessels. Thus, S. mansoni infection in the western part of Ukerewe Island is frequent and often severe, leading to a high prevalence of gastrointestinal symptoms. Hepatosplenic involvement does occur, although symptomatic cases of portal hypertension were not identified beyond doubt. The overall level of schistosomal morbidity is thus considered intermediate. Serum procollagen-IV-peptide may be a promising marker of schistosomal liver disease. Our data suggest that S. mansoni infection may also be related to diffuse liver parenchyma alterations in this area.

This is a report of our experience with 10 cases of splenic abscess in patients with sickle cell disease (SCD). All presented with fever and abdominal pain and were found to have a tender enlarged spleen. Two were found to have a ruptured spleen and five of them were septicemic on presentation. Although both ultrasound and CT-scan of the abdomen were of diagnostic value, we found CT-scan more accurate and reliable in the diagnosis of splenic abscess. Ultrasound and/or CT-scan should be used routinely in the evaluation of SCD patients who present with fever and abdominal pain, especially if they have a tender enlarged spleen. Diagnostic aspiration under CT-scan or ultrasound guidance should be used in doubtful cases to differentiate between splenic abscess and a large splenic infarct. All our patients were managed by peri operative antibiotics and splenectomy with no mortality. Salmonella was the commonest causative organism. Although CT-guided aspiration of splenic abscess is being advocated recently, we feel splenectomy should be the treatment of choice in patients with SCD as there is no point in preserving a non-functioning spleen that is present in the majority of patients. CT-guided aspiration may be employed as a temporary measure for those patients who are at high surgical risk with unilocular abscess.
