RESUMEN
Coombs' negative autoimmune hemolytic anemia (AIHA) is a rare disease which shares similar clinical and hematological features with Coombs' positive AIHA, but its exact frequency remains unknown. There have been few reports of idiopathic thrombocytopenic purpura (ITP) and Coombs' negative AIHA associated with other lymphoproliferative disorders (LPDs). Since there is a well known association between LPDs and autoimmune phenomena, it is important to investigate the possibility of an underlying malignancy. We report a case of ITP and Coombs' negative AIHA associated with diffuse large B-cell lymphoma.

BACKGROUND/AIMS: Acute viral hepatitis A infection in adults is an emerging public health problem in Korea. The infectivity and pathogenicity of hepatitis A virus (HAV) among people living in close contact have not been studied previously. This study investigated the secondary attack rate and pathogenicity rate of HAV during an outbreak among auxiliary police in a communal living setting in Korea. METHODS: A total of 70 people in close contact with a hepatitis A patient (index case) were enrolled in the study, which included a thorough oral history, physical examination, and laboratory testing. The subjects were part of an auxiliary police unit living in a communal setting (HAV contact group). Serum antibody titers were measured in the contact group at two points during the study. Subjects in another auxiliary police unit without exposure to hepatitis A were examined as a control group (HAV non-contact group). The secondary attack rate and pathogenicity rate were calculated from the data. RESULTS: In the HAV non-contact group, none of the subjects had anti-HAV antibodies. In the HAV contact group, three subjects had both IgM and IgG anti-HAV antibodies, and two had only IgG anti-HAV antibodies. Two of three HAV-infected subjects were treated for hepatitis A. CONCLUSIONS: The secondary attack rate of HAV was 4.3~7.1% and the pathogenicity rate was 40~66.7% in the group of young adults.

Pyloric gland adenoma is a recently described neoplasia that is very rare. It was first classified as a gastric tumor in 1990. Pyloric gland adenomas occur predominantly in old age, more frequently in women than in men, and they are often found in patients suffering from autoimmune gastritis. The diagnosis can be confirmed by immunohistochemistry, which is strongly positive for MUC6 and MUC5AC, expressed in the superficial layer. A pyloric gland adenoma is a type of gastric tumor, but it has also been reported in the gallbladder, pancreatic duct, duodenum, cervix of the uterus, rectum, and Barrett's esophagus. In 30% of gastric pyloric adenomas, transition to well-differentiated adenocarcinoma has been noted. Therefore, these lesionsshould be removed. In our case, the lesion was removed by endoscopic submucosal dissection. We report a case of pyloric gland adenoma in the cardia of the stomach showing typical endoscopic and microscopic features. This is the first case of pyloric gland adenoma of the stomach reported in Korea.

Extrapulmonary tuberculosis, such as intestinal tuberculosis, has become more common with the increase in human immunodeficiency virus infection. However, the diagnosis and treatment of intestinal tuberculosis are often delayed because the symptoms are nonspecific and diverse. We experienced a case of AIDS with intestinal tuberculosis that manifested as a duodenal fistula. The presence of AIDS should be suspected in patients who have extrapulmonary tuberculosis with atypical presentations.
