[Show abstract][Hide abstract] ABSTRACT: Patients with cholangiocarcinoma usually present at an advanced stage, and more than 50% of cases are not resectable at the time of diagnosis. Recently, photodynamic therapy (PDT) has been proposed as a palliative and neoadjuvant modality. We evaluated whether combination of PDT and chemotherapy is more effective than PDT alone.
In total, 161 patients with cholangiocarcinoma diagnosed between February 1999 and September 2009 were evaluated. Sixteen patients were treated with PDT and chemotherapy (group A), and 58 were treated with PDT (group B).
The median survival was 538 days (95% confidence interval [CI], 475.3 to 600.7) in group A and 334 days (95% CI, 252.5 to 415.5) in group B (p=0.05). Lymph node metastasis status, serum bilirubin of pretreatment, tumor node metastasis stage, treatment method (PDT with chemotherapy vs PDT alone), time to PDT and the number of PDT sessions were prognostic factors with statistical significance in the univariate analysis. A multivariate analysis showed that PDT with chemotherapy and more than two sessions of PDT were significant independent predictors of longer survival in advanced cholangiocarcinoma (hazard ratio [HR], 2.23; 95% CI, 1.18 to 4.20; p=0.013 vs HR, 1.79; 95% CI, 1.044 to 3.083; p=0.034).
PDT with chemotherapy results in longer survival than PDT alone.

A 74-year-old male without any sig-nificant medical history visited our center because of abdominal pain and diarrhea which began about a month ago. Abdominal computed tomography revealed segmental enhanced bowel wall thickening on jejunum and single-balloon enteroscopy showed multiple geographic shaped ulcerations covered with exudates on proximal jejunum. Biopsy samples taken during endoscopic examination demonstrated necrotic fibrinopurulent tissue debris and benign ulcer. Nested-PCR analysis of CMV DNA from jejunal tissue was positive. The patient was finally diagnosed with CMV jejunitis and was treated by intravenous ganciclovir for 14 days after which, abdominal pain and diarrhea improved. Our case shows that CMV jejunitis can occur in an im-munocompetent adult as multiple jejunal ulcers which can be diagnosed using a single-balloon enteroscope.

[Show abstract][Hide abstract] ABSTRACT: Hepatic tuberculosis is usually associated with active pulmonary or miliary tuberculosis. The occurrence of an isolated hepatic mass-forming tuberculosis with no evidence of tuberculosis elsewhere is rare. We report a case of a 31-year-old male with a solitary hepatic granuloma mimicking a mass-forming intrahepatic cholangiocarcinoma. Ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography of the abdomen showed a malignant tumor-like lesion. We then conducted endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) for confirmation of the hepatic hilar mass, which was found to be a hepatic tuberculosis granuloma as the final diagnosis.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to characterize the clinical features of acute hepatitis A in Seoul and Gyeonggi province during the recent 2 years.
We reviewed the medical records of 222 patients who were diagnosed as acute hepatitis A between August 2005 and March 2007 at the Konkuk University Hospital and Korea University, Ansan Hospital. The clinical manifestation, serological tests, and image findings were analyzed.
Median age of the patients was 28.1 years and the age groups of highest incidence were the second and third decade. The frequent symptoms were anorexia (66.4%), fatigue (49.2%), fever (47.7%), and abdominal discomfort (42.5%). Fourteen cases (6.3%) showed renal insufficiency, and hemodialysis was performed in one. Cholestatic hepatitis in 2 cases, relapsing hepatitis in 4 cases and prolonged hepatitis in 13 cases were observed. However, there was no case of fulminant hepatitis or death. The underlying diseases including chronic hepatitis B, diabetes mellitus and thyroid disorder did not affect the disease severity of hepatitis A. IgM anti-HAV was not detected initially in 6.7% of the patients. Anti-HEV (IgM) was detected simultaneously in 3 of 150 patients.
The age of patients with acute hepatitis A has been increased in the recent years. Most patients recovered uneventfully. However, unusual patterns of severe hepatitis and renal insufficiency occurred in considerable number of cases. Follow-up serologic test for IgM anti-HAV is needed in seronegative cases with hepatitis A.

[Show abstract][Hide abstract] ABSTRACT: Systemic sclerosis is an autoimmune disease, characterized by inflammation, microangiopathy and fibrosis in the skin and various intestinal organs. Gastrointestinal involvement is one of the major causes of serious morbidity, and next to the skin, the gastrointestinal tract is the most commonly involved organ. While esophageal involvement is most common gastrointestinal manifestation, the involvement of the small intestine and colon is less common but may lead to life-threatening complications like chronic pesudoobstruction or pneumatosis cystoids intestinalis. Here, we describe a case of progressive systemic sclerosis associated with intestinal pseudoobstruction. 28 year-old male presented abdominal pain and vomiting and he was diagnosed as having intestinal pseudoobstruction. His symptoms were well managed using the combination of octreotide, a long-acting somatostatin analogue, and erythromycin.
