ABSTRACT
BACKGROUND/AIMS: Early detection of gallbladder (GB) cancer is essential for better survival rates. Most cases of GB cancer are diagnosed incidentally via pathology of the cholecystectomy specimen. Data on the clinical characteristics of early GB cancer are lacking. The aim of the current study was to investigate the clinical characteristics of early GB cancer to aid earlier diagnosis. METHODS: Sixty-four patients who were diagnosed with early GB cancer after surgical resection at the Samsung Medical Center were enrolled in this study. Clinical characteristics, preoperative diagnoses, preoperative tumor size, laboratory findings including carbohydrate antigen 19-9 (CA19-9) levels, imaging features, and survival rate were investigated. RESULTS: Clinical symptoms and serum tumor markers such as carcinoembryonic antigen and CA19-9 levels were not helpful indicators of early GB cancer. Radiologic modalities showed abnormal findings in every case of early GB cancer; a polypoid mass was the most common feature. Less common features included GB wall thickening, cholecystitis, and GB stones. The clinical outcome of early GB cancer was excellent. CONCLUSIONS: Screening with imaging modalities such as computed tomography (CT) or ultrasonography (US) is helpful in detecting early GB cancer. Even in the presence of GB wall thickening, cholecystitis, or GB stones on the CT or US, any abnormal findings should prompt careful examination and intensive follow up, considering the possibility of occult gallbladder cancer.

Mycobacterium marinum is an uncommon cause of skin and soft-tissue infection. The diagnosis of M. marinum infection is often delayed when only a conventional tissue culture method is used. PCR-restriction fragment length polymorphism (RFLP) analysis using the novel region of the rpoB gene is now available for the rapid identification of Mycobacteria. We report a case of hand infection caused by M. marinum that was identified by PCR-RFLP analysis. The PCR-RFLP assay is a specific and rapid method for the identification of Mycobacteria that facilitates the early diagnosis of non-tuberculous Mycobacterium infection.

ABSTRACT
BACKGROUND/AIMS: The aim of this study was to evaluate the usefulness of health screening for early detection and improved prognosis in pancreatic cancer. METHODS: Between 1995 and 2008, 176,361 examinees visited the Health Promotion Center (HPC). Twenty patients diagnosed with pancreatic cancer were enrolled. During the same period, 40 patients were randomly selected from 2,202 patients diagnosed with pancreatic cancer at the Out Patient Clinic (OPC) for comparison. RESULTS: Within the HPC group, 10 patients were initially suspected of having pancreatic cancer following abnormal ultrasonographic findings, and 9 patients had suspected cases following the detection of elevated serum CA 19-9. The curative resection rate was higher in the HPC group than in the OPC group (p=0.011). The median survival was longer in the HPC group than in the OPC group (p=0.000). However, there was no significant difference in the 3-year survival rate between the two groups. Asymptomatic patients (n=6/20) in the HPC group showed better curative resection and survival rates than symptomatic patients. However, the difference was not statistically significant. CONCLUSIONS: Health screening is somewhat helpful for improving the curative resection rate and median survival of patients with pancreatic cancer detected by screening tests. However, the benefit of this method in improving long-term survival is limited by how early the cancer is detected.

Endocardial fibroelastosis (EFE) is characterized by deposition of collagen and elastin leading to ventricular hypertrophy and diffuse endocardial thickening. Here we report (for the first time in Korea) the case of a EFE presenting with heart failure. The patient was a 57-year-old woman who had complained of dyspnea on exertion {New York Heart Association (NYHA) functional class 3} and abdominal distension at the time of hospital admission. Echocardiography showed severe diastolic dysfunction with normal systolic function. On MRI, the contrast-enhanced delayed myocardial image demonstrated hyperenhancement in the endocardium. Owing to progressive heart failure, the patient was transplanted. Histological examination of the explanted heart showed irregularly thickened endocardium with fibrosis and elastosis in the both ventricles, compatible with the diagnosis of EFE.

Presented is a case study of a 39-year-old man with chronic thromboembolic pulmonary hypertension (CTEPH) and an underlying antithrombin III (AT III) deficiency. The subject presented with severe dyspnea (NYHA functional class III). A diagnostic workup led to a diagnosis of pulmonary thromboembolism and severe pulmonary hypertension with right ventricular failure. Genetic analysis revealed a novel nonsense mutation (c.243G>A) in SERPINC1. Pulmonary thromboendarterectomy was performed following the insertion of an inferior vena cava filter. After one year, the subject remained in NYHA functional class I and exhibited normal right ventricular function. This is the first report of a genetically confirmed AT III deficiency complicated by CTEPH in Korea.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder that is characterized by multiple cutaneous vascular malformations in the skin and gastrointestinal tract and is associated with intestinal hemorrhage and iron deficiency anemia. This syndrome may induce severe or fatal bleeding; however, the causes of this syndrome are unknown. We report here a case of BRBNS that was diagnosed in a 20-year-old male with chronic anemia and a past history of surgery due to cutaneous hemangioma on the shoulder and thigh. One purplish hemangioma on the stomach and multiple bluish hemangiomas on the colon were noted on the endoscopic examination. We successfully treated the GI hemangioma with endoscopic band ligation and endoscopic polypectomy.

Eosinophilic gastritis is a rare disease that is characterized by eosinophilic infiltration of the bowl wall tissue, and the presentation of symptoms varies depending on the affected site. It is likely that eosinophil-active cytokines play important roles in this disease. A 22-year old man presented with abdominal pain and vomiting. Endoscopic gastric biopsy revealed eosinophilic infiltration, and the serum level of Interleukin (IL)-5 was increased. Gastric emptying was moderately delayed in this patient. The patient was treated with steroid and he showed dramatic clinical improvement with disappearance of the eosinophilic infiltration of the gastric mucosa, normalization of the serum level of IL-5 and improvement of the gastric emptying time. There has been few case reports of eosinophilic gastritis that have described the change of the serum level of cytokines and the gastric emptying. We report here on a case of eosinophilic gastritis and the patient showed elevated serum level of cytokines and delayed gastric emptying. The patient improved after being treated with steroid.

Nontuberculous mycobacterial infection is rarely accompanied by pleural involvement. We report a very rare case of Mycobacterium intracellulare pulmonary disease accompanied with pleural effusion. A 76-year-old man was admitted to our hospital because of dyspnea. A chest radiograph and CT showed bilateral bronchiectasis and bronchopneumonia accompanied with right pleural effusion. The fluid was lymphocyte-dominant exudative effusion, and microbiological examinations of the effusion, including staining and culturing, proved negative. However, one month after admission, subsequent cultures of bronchial washing fluid revealed the presence of M. intracellulare. The patient's effusion was gradually resolved with antibiotic treatment, including clarithromycin.
