Endoscopic retrograde cholangiopancreatography is widely used for diagnosis and treatment of pancreatobiliary diseases and associated with a spectrum of complications such as pancreatitis, hemorrhage, and so on. Endoscopic papillary balloon dilatation (EPBD) has an advantage over endoscopic sphincterotomy in complication of bleeding. We report here on a 68-year-old woman who developed metabolic encephalopathy due to massive bleeding after EPBD. Massive bleeding was controlled after selective embolization and metabolic encephalopathy was improved after conservative management. Metabolic encephalopathy due to massive bleeding after EPBD has not been reported. We report on this unusual case along with a review of the related literatures.

The role of carcinoembryonic antigen (CEA) in pancreatic cancer remains poorly understood. Therefore, this study aimed to determine whether CEA is complementary to carbohydrate antigen 19-9 (CA19-9) in prognosis prediction after pancreatic cancer curative resection. We retrospectively reviewed records of 144 stage II curatively resected pancreatic cancer patients with preoperative and postoperative CEA and CA19-9 levels. Patients with normal preoperative CA19-9 were excluded. R0 resection margin, adjuvant treatment, and absence of angiolymphatic invasion were associated with better overall survival. There was no significant difference in median survival according to preoperative CEA levels. However, patients with normal postoperative CA19-9 (59.8 vs.16.2 months, P < 0.001) and CEA (29.4 vs. 9.3 months, P = 0.001) levels had longer overall survival than those with elevated levels. Among 76 patients with high postoperative CA19-9 levels, a better prognosis was observed in those with normal postoperative CEA levels than in those with elevated levels (19.1 vs. 9.3 months, P = 0.004). Postoperative CEA and CA19-9 levels are valuable prognostic markers in resected pancreatic cancer. Normal postoperative CEA levels indicate longer survival, even in patients with elevated postoperative CA19-9.

BACKGROUND: A mummy is a dead body of a human being or an animal that has been preserved artificially or naturally from decaying. Because the natural environment of Korea isn't appropriate for mummification and Korean people haven't artificially made mummies, mummies were rarely studied in Korea. METHODS: On September 6, 2002, a well-preserved female mummy was found in the grave of a family in Kyunggi-do. She was submitted to a thorough autopsy examination along with the review of genealogical documents. RESULTS: The mummy died in winter. She was pregnant and the fetal head was observed at the vaginal orifice. The uterine wall was ruptured, and the peritoneum was discolored, probably by hemorrhage. Histologically, the gastric mucosa was well preserved. On the smear cytology of gastrointestinal material and the fluid from the coffin, pollens and parasitic eggs were observed. The woman seemed to be death from hypovolemic shock due to uterine rupture during the 2nd phase of labor. CONCLUSION: From this case, we concluded the causes of the woman's mummification included the cold and dry circumstance at the time of her death, and the thick mortared wall of the grave that completely isolated the body from the outside.

Mesenteric panniculitis (MP) is non-specific inflammation of the adipose tissue that primarily involves the small bowel mesentery. Omental involvement has been rarely reported but we report a case of 25 years old woman with isolated lesser omental panniculitis. This patient was diagnosed by CT findings and recovered completely with conservative treatment. Invasive diagnostic methods or surgical exploration has been used to diagnose MP. However, all six reported cases of omental panniculitis including the current case showed a benign course; therefore, awareness of the CT findings is essential for the best diagnosis and management of omental panniculitis.

Duloxetine is a balanced serotonin and norepinephrine reuptake inhibitor available for treating peripheral neuropathic pain. The occurrence of hyponatremia as an adverse event of duloxetine treatment, but it has not yet been reported in Korea. Here, we report two cases of hyponatremia induced by duloxetine for treatment of peripheral neuropathic pain. Our findings highlight the need for special attention when using duloxetine in elderly patients taking thiazide diuretics.

Background/Aims: Postbronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) less than 0.7 using spirometry is the golden standard to diagnose airf low limitation of chronic obstructive pulmonary disease (COPD). Recently, measuring FEV6 has been suggested as an alternative to measure FVC. Studies about the cut-off value for FEV1/FEV6 to diagnose airflow limitation have shown variable results, with values between 0.7 and 0.8. The purpose of this study was to determine the best cut-off value of FEV1/FEV6 to detect airflow limitation using handheld spirometry. Methods: We recruited subjects over 40 years of age with smoking history over 10 pack-years. Participants underwent measurements with both handheld spirometry and conventional spirometry. We calculated the sensitivity and specificity of the value of FEV1/FEV6 using receiver-operating characteristic (ROC) curve analysis to obtain the diagnostic accuracy of handheld spirometry to detect airflow limitation. Results: A total of 290 subjects were enrolled. Their mean age and smoking amount were 63.1 years and 31.6 pack-years, respectively. According to our ROC curve analysis, when FEV1/FEV6 ratio was 73%, sensitivity and specificity were the maximum and the area under the ROC curve was 0.93, showing an excellent diagnostic accuracy. Sensitivity, specificity, positive predictive value, and negative predictive value were 86.7%, 89.7%, 88.0%, and 88.5%, respectively. Participants with FEV1/FEV6 ≤ 73% had lower FEV1 predicted value compared to those with FEV1/FEV6 > 73% (65.4% vs. 86.5%, p < 0.001). Conclusions In summary, we demonstrate that the value of 73% in FEV1/FEV6 using handheld spirometry has the best sensitivity and specificity to detect airflow limitation in subjects with risk of COPD.

Fascioliasis is a zoonotic infection caused by Fasciola hepatica or Fasciola gigantica. We report an 87-year-old Korean male patient with postprandial abdominal pain and discomfort due to F. hepatica infection who was diagnosed and managed by endoscopic retrograde cholangiopancreatography (ERCP) with extraction of 2 worms. At his first visit to the hospital, a gallbladder stone was suspected. CT and magnetic retrograde cholangiopancreatography (MRCP) showed an intraductal mass in the common bile duct (CBD) without proximal duct dilatation. Based on radiological findings, the presumed diagnosis was intraductal cholangiocarcinoma. However, in ERCP which was performed for biliary decompression and tissue diagnosis, movable materials were detected in the CBD. Using a basket, 2 living leaf-like parasites were removed. The worms were morphologically compatible with F. hepatica. To rule out the possibility of the worms to be another morphologically close species, in particular F. gigantica, 1 specimen was processed for genetic analysis of its ITS-1 region. The results showed that the present worms were genetically identical (100%) with F. hepatica but different from F. gigantica.

BACKGROUND: The fact that only 10-20% of chronic cigarette smokers develop chronic obstructive pulmonary disease (COPD) reflects the presence of genetic factors associated with the susceptibility to COPD. Recently, it was reported that the surfactant protein A increases the secretion of matrix metalloprotease 9, which degrades extracellular matrices of the lung, through a Toll-like receptor 2 (TLR2). In this context, possible role of TLR2 in the pathogenesis of COPD was postulated, and a functional dinucleotide repeat polymorphism in intron II of TLR2 was evaluated for any association with COPD. METHOD: Male patients with COPD and male smokers with a normal pulmonary function were enrolled in this study. The number of Guanine-Thymine repeats in intron II of the TLR2 gene were counted. Because the distributions of the repeats were trimodal, the alleles were classified into three subclasses, 12-16 repeats: short (S) alleles; 17-22 repeats: medium length (M) alleles; and 23-27 repeats: long (L) alleles. RESULT: 125 male patients with COPD and 144 age- and gender-matched blood donors with a normal lung function were enrolled. There were no differences in the distribution of each allele subclass (S, M and L) between the COPD and control group (p=0.75). The frequencies of the genotypes with and without each allele subclass in the COPD and control group were similar. CONCLUSION: A microsatellite polymorphism in intron II of TLR2 gene was not associated with the development of COPD in Koreans.

Low-grade endometrial stromal sarcoma (ESS) is an uncommon gynecologic malignancy of mesodermal origin. Pulmonary metastasis of low-grade ESS can occur years and decades after the treatment of the primary disease. Low-grade ESS is frequently mistaken as benign uterine neoplasm like uterine leiomyoma, which can potentially lead to a misdiagnosis. We present a case of a 42-year-old woman with low-grade ESS, that initially presented as an incidental lung mass with multiple pulmonary nodules, seven years after an uterine myomectomy. A 6.9x5.8 cm-sized intrapelvic mass suspected of uterine origin was discovered while searching for potential extrathoracic primary origin. A pelviscopy and simultaneous thoracoscopic lung biopsy were conducted for pathologic diagnosis. Finally, the diagnosis was confirmed as low-grade ESS with lung metastasis based on the histopathologic examination with immunohistochemical stain, which was showed positive for CD10 and hormone receptor markers (estrogen and progesterone receptors) in both pelvic and lung specimens.
