Intestinal microsporidiosis in HIV-infected children with diarrhea.

Intestinal microsporidiosis is a common opportunistic disease associated with diarrhea in adult AIDS patients in Thailand; the data regarding this infection in children are scarce. The present study was designed to investigate the prevalence and clinical features of intestinal microsporidiosis in hospitalized HIV-infected and uninfected (free of HIV) children with diarrhea. Of the 95 HIV-infected children and 87 uninfected children, 24 (25.

Intestinal microsporidiosis in HIV infected patients with chronic diarrhea in Thailand.

Microsporidia have been recognized as emerging opportunistic agents affecting multiple organs. Intestinal microsporidiosis caused by Enterocytozoon bieneusi and Encephalitozoon intestinalis is a common disease which is associated with gastrointestinal symptoms, particularly in AIDS patients. So far, information on the frequency of this enteric disease in Thailand is not available.

Malignant carcinoid tumor of the appendix with liver and lung metastasis: report of a case with a high level of serum carcinoembryonic antigen.

We report elevated serum carcinoembryonic antigen (CEA) in a case of malignant carcinoid tumor of the appendix with liver and lung metastasis. A 55-year-old Thai man was found to have multiple nodules in the liver by ultrasonography. Serum CEA was 7,387.

Clofazimine-induced crystal-storing histiocytosis producing chronic abdominal pain in a leprosy patient.

Clofazimine-induced crystal-storing histiocytosis is a rare but well-recognized condition in the literature. Besides the common reddish discoloration of the skin, clofazimine produces gastrointestinal disturbances-sometimes severe abdominal pain, prompting exploratory laparotomy, because pathologic and radiologic findings can produce diagnostic difficulties if the pathologic changes caused by clofazimine are not recognized. The authors report such a case in a leprosy patient to emphasize the importance of history taking, the radiologic abnormalities of the small intestine, and the pathologic findings in small intestine and lymph node biopsies.

Pulmonary dirofilariasis in a patient with multisystem Langerhans cell histiocytosis--the first reported case in Thailand.

Despite a high prevalence of canine dirofilariasis, there is no case of pulmonary dirofilariasis reported from Thailand. We herein report a case of multisystem Langerhans cell histiocytosis who had an incidental pulmonary dirofilariasis found at the time of autopsy as a solitary nodule at the periphery of the right lower lobe. This is the first reported case in Thailand.
