Mechanical obstruction of the common hepatic duct includes the following causes; choledocholithiasis, sclerosis, cholangitis, pancreatic carcinoma, cholangiocarcinoma, postoperative stricture, primary hepatic duct carcinoma, enlarged cystic duct lymph nodes, and metastatic nodal involvement of the porta hepatis. Partial mechanical obstruction of the common hepatic duct caused by impaction of stones and inflammation surrounding the vicinity of the neck of the gallbladder had been reported on the “syndrome del conducto hepatico” in 1948 by Mirizzi. Nowadays, this disease was named by Mirizzi syndrome. Mrizzi syndrome is a rare entity of common hepatic duct obstruction that results from an inflammatory response secondary to a gallstone impacted in the cystic duct or neck of the gallbladder. It results from an almost parallel course and low insertion of the cystic duct into the common hepatic duct. In a variant of Mirizzi's syndrome, the cause of the common hepatic duct obstruction was a primary cystic duct carcinoma rather than gallstone disease. A 71-year-old man was admitted with a four-day history of right upper quadrant abdominal pain. Past medical history was unremarkable. On physical examination, the patient had a temperature of 38℃, icteric sclera and right upper quadrant tenderness. Pertinent laboratory findings included WBC 18,000/cm3; albumin 2.6 g/dl (normal 0-1) with the direct bilirubin, 4.4 mg/dl (normal 0-0.4). Ultrasonography revealed a dilated extrahepatic biliary tree. ERCP showed that the superior margin was angular and more consistent with a calculus causing partial CHD obstruction (Mirizzi syndrome). At surgery a diseased gallbladder containing calculi was found. In addition, there was two calculi partially eroding through the proximal portion of the cystic duct and compressing the common hepatic duct. A cholecystectomy and excision of common bile duct was performed, with Roux-en-Y hepaticojejunostomy. The postoperative course was uneventful.

PURPOSE: We evaluated the effect of adjuvant radiotherapy on survival in patients who underwent curative resection for gallbladder cancer with lymph node metastasis. METHODS: Among the patients underwent curative resection even though there was lymph node metastasis; fifteen patients underwent adjuvant radiotherapy with over 40 Gy (RTx group) and 10 patients did not (no RTx group). We compared these two groups retrospectively. RESULTS: The median disease free survival (DFS) of the RTx group (21.6 months) was longer than for the no RTx group (6.6 months, p=0.451). The median overall survival (OS) of the RTx group (30.5 months) was also longer than the no RTx group (14.2 months). One-, 2-, and 5-yr OS rates were 60.0%, 40.0% and 40.0% in the no RTx group, and 86.7%, 70.9% and 26.6% in the RTx group, respectively (p=0.507). Five patients developed recurrence within 1 year (50.0%) in the no RTx group; there were 3 (20.0%) in the RTx group. CONCLUSION: Our study was limited by its retrospective nature and small numbers of patients. However, it suggests that adjuvant radiotherapy might improve DFS and OS for patients with completely resected but lymph node metastasized gallbladder cancer. Also this therapy seems to delay time to postoperative recurrence.

The purpose of this survey was to obtain information on the prevalence, costs, and patterns of use of complementary and alternative medicine (CAM) in a general population in the Republic of Korea. In 2006, we conducted nationwide and population- weighted personal interviews with 6,021 adults ranging from 30 to 69 yr of age; the final sample consisted of 3,000 people with a 49.8% response rate. In addition to their general socio-demographics, the respondents were asked about their use of CAM during the previous 12-month period, costs, sources of information, and reasons for use. The prevalence of use overall was 74.8%, while biologically based CAM therapies were the most likely type of use (65.4%). The median annual out-of-pocket expenditures for CAM therapies was about US$203. The primary reason for using CAM was for disease prevention and health promotion (78.8%). The main source of advice about CAM therapies use was most likely to be from family and friends (66.9%). Our study suggests that CAM use has been and continues to be very popular in South Korea. Conventional western medical doctors and governments should obtain more evidence and become more interested in CAM therapies.

Extragonadal choriocarcinoma arising in the stomach of a 53-year-old male is presented. The tumor was diagnosed as choriocarcinorna of the stomach by histologic examination and immunohistologic method of biopsy specimens. The tumor showed the multiple metastases to the lung and liver. The level of human chorionic gonadotropin was significantly increased in the serum. The patient died of hepatic failure at the 26th hospital day.

Neurofibrillary tangle (NFT) is a characteristic hallmark of Alzheimer's disease. GSK3beta has been reported to play a major role in the NFT formation of tau. Dysfunction of autophagy might facilitate the aggregate formation of tau. The present study examined the role of GSK3beta-mediated phosphorylation of tau species on their autophagic degradation. We transfected wild type tau (T4), caspase-3-cleaved tau at Asp421 (T4C3), or pseudophosphorylated tau at Ser396/Ser404 (T4-2EC) in the presence of active or enzyme-inactive GSK3beta. Trehalose and 3-methyladenine (3-MA) were used to enhance or inhibit autophagic activity, respectively. All tau species showed increased accumulation with 3-MA treatment whereas reduced with trehalose, indicating that tau undergoes autophagic degradation. However, T4C3 and T4-2EC showed abundant formation of oligomers than T4. Active GSK3beta in the presence of 3-MA resulted in significantly increased formation of insoluble tau aggregates. These results indicate that GSK3beta-mediated phosphorylation and compromised autophagic activity significantly contribute to tau aggregation.

Purpose: Immunochemical fecal occult blood tests (iFOBT) have been utilized as the primary method for colorectal cancer screening within Korea's National Cancer Screening Program. This study aimed to evaluate the impact of the accreditation program for clinical laboratories and external quality assessment (EQA) programs on colorectal cancer screening. Methods: We analyzed the false-positive rates of iFOBT in colorectal cancer screening from 2016 to 2020 according to participation and performance in the Outstanding Laboratory Accreditation Program (OLAP) conducted by the Laboratory Medicine Foundation, and the External Quality Assessment programs run by the Korean Association of External Quality Assessment Service. Results: False-positive rates of iFOBT were lower among institutions accredited by OLAP (2.35%) compared with non-accredited (3.04%) and non-participating institutions (5.60%). Similarly, institutions participating in the EQA program exhibited lower false-positive rates (3.79%) compared to non-participants (7.04%). Within the iFOBT-specific EQA program, institutions that passed demonstrated the lowest false-positive rate (3.37%), while failing institutions showed the highest rate (9.07%), surpassing even non-participating institutions (6.44%). Conclusion Participation in quality management programs such as OLAP and EQA was associated with lower false-positive rates in iFOBT for colorectal cancer screening. These findings suggest that quality management initiatives can increase the accuracy of iFOBT, potentially improving the effectiveness of colorectal cancer screening programs, and reducing unnecessary follow-up procedures and associated healthcare costs.
