ABSTRACT
Schistosomiasis is a parasitic disease caused by Schistosoma species. Intestinal and hepatic schistosomiases are the most common forms of chronic disease. We describe a case of a 26-year old patient from Eritrea who was referred to our hospital with abdominal pain and diarrhea. The diagnosis of hepatosplenic schistosomiasis was made by liver biopsy and the patient was treated with praziquantel. Hepatic schistosomiasis is characterised by deposition of schistosomal eggs in the liver which results in a host cell immune response and leads to granuloma formation and neoangiogenesis. This is hallmarked by different grades of periportal fibrosis with portal hypertension leading to splenomegaly. Normal liver architecture is preserved and periportal fibrosis can be reversible if treated adequately and timely. With a recent native schistosomiasis cluster report from France and the expected influx to Europe of persons from regions endemic for schistosomiasis, increased awareness of this disease in healthcare practitioners is needed. We review the epidemiology, pathogenesis, clinical presentation and treatment of schistosomiasis.

An ex-coal miner was diagnosed with an idiopathic sigmoiditis compatible with colitis ulcerosa. He was treated with corticosteroids because of his deteriorating clinical condition, but his condition continued to worsen. He revealed to have a systemic Strongyloides stercoralis hyperinfection and Strongyloides colitis. A short time after diagnosis he died from septic shock despite therapy with thiabendazole and antibiotics. S. stercoralis is an opportunistic infection that is not uncommon and has high mortality in hyperinfection. It is prevalent in (sub)tropical areas, and also in coal mines because of the specific microclimate. However, the parasite is difficult to detect because eosinophilia can appear normal in chronic infection. Several stool examinations, duodenal aspiration or biopsies are necessary for a high diagnostic sensitivity. Serological diagnosis is the most sensitive and specific but is not always available.

Laser has become in the recent years an important therapeutic tool for treating esophageal cancer in a palliative setting aiming to reopen the tumor stenosis. The literature shows that the initial enthusiasm for laser, compared with other methods--especially endoprosthesis--has somewhat been tempered because the success rate in restoring a normal food intake was lower than expected (65-68%). Although the complication rate is low, repeated therapy sessions are needed to maintain the lumen open. This constitutes a major drawback in terms of patient acceptability. Variations in the therapeutical methods (contact laser, photodynamic therapy, ...) have not added up to now significant value to laser therapy. Specific indications for laser therapy versus endoprosthesis are discussed and should bring both therapeutic modalities to a more considered application.
