Associations between Nonalcoholic Fatty Liver Disease and Colorectal Adenoma in Health Screen Examinees / 대한소화기내시경학회지

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) and colorectal cancer share several risk factors. However the relationship between NAFLD and colorectal adenoma is unclear. Therefore, we investigated the possibility of an association between NAFLD and colorectal adenoma. METHODS: We reviewed the records of 3,106 subjects who had undergone colonoscopy and abdominal ultrasonography between April 2007 and August 2009. RESULTS: The sex ratio (male/female) was 4.94:1 and the mean age was 50.6+/-9.7 years in patients with colorectal adenoma; the corresponding numbers were 2.23: 1 and 45.0+/-9.2 years in patients without colorectal adenoma (p<0.001). The prevalence of NAFLD was 26.0% in the adenoma group and 21.4% in the control group (p=0.013). Additionally, there were positive associations between colorectal adenoma and BMI and lipid profile. Among the risk factors selected by univariate analysis, older age (OR 2.592; 95% CI 2.087~3.219), and being male (OR 2.470; 95% CI 1.878~3.247) were independent risk factors for colorectal adenoma. Patients with NAFLD had more colorectal adenomas (p=0.005) and their adenomas were located more in the proximal colon (p=0.009). CONCLUSIONS: NAFLD is not associated with increased risk for colorectal adenoma. However, among patients with NAFLD, colorectal adenomas were likely to be increased in number and they were likely to be located in the proximal colon.

A case of diffuse alveolar hemorrhage with thoracocervicofacial purpura after a generalized tonic-clonic seizure / 대한내과학회지

A 40-year-old woman presented with hemoptysis and thoracocervicofacial purpura that occurred after a generalized tonic-clonic seizure. Diffuse alveolar hemorrhage is reported relatively rarely in neurogenic pulmonary edema (NPE), which is a life-threatening postictal complication. This clinical setting causes difficulty in the diagnosis, when an accurate diagnosis and proper management are required. Thoracocervicofacial purpura has been described as an unusual setting for an epileptic seizure. Here, we report the first case of postictal diffuse alveolar hemorrhage with thoracocervicofacial purpura.

A Case of Acute Lymphoblastic Leukemia Accompanied with Lactic Acidosis and Kidney Enlargement

There have been several reported cases of acute lymphoblastic leukemia with severe lactic acidosis in adults. In these cases, kidney and liver enlargement that was caused by leukemic infiltration frequently accompanied the acute lymphoblastic leukemia and severe lactic acidosis. Chemotherapy is the only treatment that can rapidly correct the lactic acidosis and normalize the liver and kidney enlargement. We report here on a case of acute lymphoblastic leukemia that was accompanied with severe lactic acidosis and kidney enlargement.

Dramatic Tumor Response to 2nd-line Pemetrexed/Cisplatin Combination Chemotherapy in Patient with Malignant Pleural Mesothelioma / 결핵및호흡기질환

Malignant pleural mesothelioma (MPM) is a rare tumor that is difficult to clearly distinguish from an adenocarcinoma but usually has a poor prognosis. Numerous cytotoxic agents have been used in the primary treatment of MPM with limited success. A complete response is unusual and a partial response occurs in less than one-third of patients. Recently, a phase III trial showed that a combination of pemetrexed with cisplatin resulted in a significantly higher response rate and median survival time than with cisplatin alone. We encountered a case of a dramatic tumor response to pemetrexed/cisplatin combination chemotherapy in patients with MPM, which was resistant to the 1st-line gemcitabine/cisplatin therapy. After six cycles of pemetrexed/cisplatin combination chemotherapy, the tumor volume had decreased dramatically with complete symptom relief. There was no chemotherapy-related toxicity or scheduled violation. The patient is under maintenance chemotherapy with the same regimen.
