A case of superior mesenteric artery syndrome due to peritoneal seeding in a colon cancer patient / 대한내과학회지

Small bowel obstruction can develop from adhesions, hernias, and less frequently from tumors. Superior mesenteric artery (SMA) syndrome is an uncommon cause of small bowel obstruction. We experienced a case of SMA syndrome caused by peritoneal seeding from colon cancer. A 57-year-old woman presented with nausea, post-prandial vomiting, and weight loss. She had been receiving palliative chemotherapy for 12 months to treat colon cancer with peritoneal seeding. Abdominal computed tomography and a small bowel series revealed typical findings of SMA syndrome. As conservative treatment including nutritional support and positional change was ineffective, she was treated surgically. An adhesive mass compressing the SMA and duodenum was found at the third portion of the duodenum. The pathologic diagnosis was metastatic adenocarcinoma of colorectal origin. Adhesiolysis and duodenojejunostomy relieved her symptoms. This case shows that SMA syndrome can develop via peritoneal seeding in cancer patients.

The Prevalence of Initial Drug Resistance among Pulmonary Tuberculosis Patients / 결핵및호흡기질환

BACKGROUND: Drug resistant tuberculosis (TB) in patients who have not received previous TB treatment (initial drug resistance) is a serious problem for the control of TB. However, prevalence of initial drug resistance among pulmonary TB patients has not been well characterized in Korea, especially in the private sector. We assessed the prevalence of initial drug resistance and evaluated the risk factors for drug resistance in pulmonary TB patients, at a regional tertiary hospital in Cheonan. METHODS: We performed a drug susceptibility test for both first and second line anti-TB drugs in all culture-confirmed pulmonary TB patients who had not received a previous TB treatment at Dankook University Hospital from September 2005 to September 2007. In addition, we evaluated the initial drug resistance pattern and clinical characteristics of patients to evaluate the risk factors for initial drug resistance. We also assessed the influence of the drug susceptibility test results on the treatment regimen. RESULTS: Of the total 156 cases where the drug susceptibility test was performed, resistance to at least one anti-TB drug was found in 21 cases (15.6%) and multidrug resistance, where TB was resistant to at least isoniazid and rifampin, was found in one case (0.6%). Multivariate logistic regression showed no clinical characteristics were independently associated with initial drug resistance. Of the total 156 patients who underwent the drug susceptibility test, the treatment regimen was changed for 15 patients (9.6%) according to the results of the drug susceptibility test. CONCLUSION: Initial drug resistance is common and the drug susceptibility test is informative for pulmonary TB patients who have not received previous TB treatment.

Clinical, Radiological and Pathological Exploration of Focal Nodular Hyperplasia of Liver Reported in Korea / 대한소화기학회지

BACKGROUND/AIMS: Focal nodular hyperplasia (FNH) is mandatory to be differentiated from other hepatic tumorous conditions such as hepatocellular carcinoma and adenoma. The purpose of this study was to explore the clinical, radiological and pathological features of FNH cases reported in Korea. METHODS: We have searched the journals from the web site "http://koreamed.org" using keywords "focal nodular hyperplasia" and "liver" - total of 38 cases of FNH, 37 cases from 17 published articles and one case from our experience confirmed histologically, were reviewed and analyzed. RESULTS: Thirty eight cases were diagnosed between gestational age of 36 weeks and 67 years. Seventeen female patients (45%) had no history of taking oral contraceptives. Twenty cases (52.6%) experienced clinical symptoms such as abdominal pain and palpable mass. Computed tomography revealed contrast-enhancement in 34 nodules (85%) and typical central stellate scar in 9 (22.5%) of 40 nodules. Magnetic resonance imaging showed T1 weighted low signal in 18 (60%) and T2 weighted high signal in 22 (73.3%) of 30 nodules. Six (60%) of 10 cases showed hypervascular staining on hepatic angiography. Among 38 cases, 32 (84.2%) cases had single nodule and their mean size was 3.9 cm (0.5-16 cm). Pathologically, fibrous septa, proliferation of bile ductules and arterial wall thickening were seen in most cases. CONCLUSIONS: Of all the FNH cases reported in Korea, there were some differences in clinical aspects of sex ratio, accompanying clinical symptoms, and relationship with oral contraceptives, compared with previous reports. Further prospective studies are needed by means of nation-wide clinical survey and analysis.

A Case of Pulmonary Trichomoniasis in a Young Healthy Male / 결핵및호흡기질환

Bronchopulmonary infections caused by trichomonads have been reported principally in patients with pre-existing pulmonary diseases, such as bronchial carcinoma, lung abscess, or bronchiectasis. Pulmonary trichomoniasis is most often caused by Trichomonas tenax, which is usually regarded as a harmless commensal organism of the human mouth. However, pulmonary infection may rarely be caused by other trichomonas species, including Trichomonas vaginalis from the genitourinary tract and Trichomonas hominis from the intestines. Because of the rarity of trichomonas pulmonary infection, and because of its close association with underlying lung and systemic disease, pulmonary trichomoniasis is considered an opportunistic infection. We recently treated a case of pulmonary trichomoniasis occurring in a young, healthy male without obvious underlying pulmonary or systemic illness. To our knowledge, there has been only one reported case of pulmonary trichomoniasis in Korea, and there have been only two reported cases of pulmonary trichomoniasis occurring in normal lung worldwide.

A Case of Malignant Gastrointestinal Stromal Tumor of Ileum with Liver Abscess / 대한소화기학회지

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor of the gastrointestinal tract and is generally located in the stomach and small intestine. They usually present with abdominal pain, gastrointestinal bleeding, and palpable mass. Some patients present with rare symptoms that are more common in malignant GIST. Malignant GIST combined with a liver abscess has not been reported yet in the literatures. We report a case of 67-year-old woman who suffered from liver abscess combined by malignant GIST with central necrosis and fistula in the ileum. She complained of fever, chills, and abdominal pain. Abdominal CT scan showed huge liver abscess and ileal mass with air pocket. Small bowel series showed contrast material filling into the ileal GIST mass. An operation was performed and the final diagnosis was malignant GIST of the ileum with invasion into the sigmoid colon and urinary bladder.
