Drug-induced liver injury (DILI) is an increasingly common cause of acute hepatitis. We examined clinical features and types of liver injury of 65 affected patients who underwent liver biopsy according DILI etiology. The major causes of DILI were the use of herbal medications (43.2%), prescribed medications (21.6%), and traditional therapeutic preparations and dietary supplements (35%). DILI from herbal medications, traditional therapeutic preparations, and dietary supplements was associated with higher elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels than was DILI from prescription medications. The types of liver injury based on the R ratio were hepatocellular (67.7%), mixed (10.8%), and cholestatic (21.5%). Herbal medications and traditional therapeutic preparations were more commonly associated with hepatocellular liver injury than were prescription medications (P = 0.002). Herbal medications and traditional therapeutic preparations induce more hepatocellular DILI and increased elevations in AST and ALT than prescribed medications.

As an adjunct to cancer treatment, the use of health functional foods (HFFs) seems to be increasing. However, little is known for the use of HFFs among cancer patients in Korea. The aims of this study were to investigate the exposure rate of HFF use among gastrointestinal (GI) cancer patients and to examine the relationship of socio-demographic and disease-related characteristics with the use of HFFs. A total of 126 patients diagnosed with GI cancer participated in the study. A cross-sectional survey was conducted using a questionnaire. Over a half of all the patients surveyed (n = 67; 53.2%) used HFFs. Patients who were younger, had higher income, or longer duration of disease showed a trend to use HFFs more frequently, even though the tendency was not statistically significant. The most commonly used HFF was vitamin complex (n = 20; 16%), followed by red ginseng (n = 15; 12%), and sweet wormwood (Artemisia annua) (n = 11; 8.8%). About 26% of all responders expressed concerns for using HFFs. The primary concern was 'going against physician's recommendations' (36.8%). About 63% of respondents expressed a desire to consult with their physicians and follow their recommendations. More basic scientific data and educational materials regarding HFFs are required for both health-care professionals and cancer patients. A larger sample and size-controlled groups representing each cancer type will continue to be recruited for participation in this survey.

The supraclavicular lymph node (SCN) is frequently involved in lymphoma and metastatic malignancies of the breast and lung, but is extremely rarely involved in pancreatic cancer. Only 10 such cases have been reported in the medical literature worldwide. We herein report an additional two cases. An 83-year-old male patient had a 7.6 x 5 cm pancreatic tumor from the pancreatic head to tail, and a 71-year-old male patient had a 2.8 x 1.9 cm pancreatic body tumor. PET-CT revealed SCN metastasis, and subsequent excisional biopsy confirmed metastatic adenocarcinoma. With the more popular use of PET-CT in patients with pancreatic cancer, the number of cases of metastasis to the SCN is expected to increase. This suggests that lymphatic spread is the main metastatic route in pancreatic cancer. Further large-scale studies along with increased numbers of case reports are needed to determine whether lymphatic spread is the main metastatic route in pancreatic cancer.

It is generally accepted that vigorous exercise may trigger cardiovascular accidents if underlying cardiovascular disease is present. Coronary artery disease is the most frequent cause of sudden cardiac arrest, especially in older individuals (> or = 35 years of age). We describe two patients who presented with cardiac arrest followed by loss of consciousness. Both had been participating in a marathon race. After acute myocardial infarction was diagnosed by electrocardiography and laboratory findings, urgent percutaneous coronary intervention was performed on both patients.

Rhabdomyolysis is a syndrome involving the breakdown of skeletal muscle that causes myoglobin and other intracellular proteins to leak into the circulatory system, resulting in organ injury including acute kidney injury. We report a case of statin-induced rhabdomyolysis and acute kidney injury that developed in a 63-year-old woman with previously undiagnosed hypothyroidism. Untreated hypothyroidism may have caused her hypercholesterolemia requiring statin treatment, and it is postulated that statin-induced muscle injury was aggravated by hypothyroidism resulting in her full-blown rhabdomyolysis. Although this patient was successfully treated with continuous venovenous hemofiltration and L-thyroxin replacement, rhabdomyolysis with acute kidney injury is a potentially life-threatening disorder. Physicians must pay special attention to the possible presence of subclinical hypothyroidism when administering statins in patients with hypercholesterolemia.

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is characterized by cystic dilatation of the pancreatic duct, excessive mucin production, and papillary growth of the tumor. Occasionally, it forms a fistula into other organs. Because of the higher malignant potential of the main duct type IPMN compared to the branch duct type, patients with main duct type IPMN usually undergo surgical treatment and the natural history of the main duct type IPMN is not commonly observed in clinical practice. An 84-year-old woman was diagnosed with main duct type IPMN of pancreas, but she refused operative treatment. Seven years later she was admitted by chance for another disease, and then referred to our gastrointestinal department. We think this case can give us an insight of the natural course of the main duct type IPMN.

BACKGROUND: Diamond Blackfan anemia (DBA), characterized by impaired red cell production, is a rare condition that is usually symptomatic in early infancy. The purpose of this study was to assess nationwide experiences of DBA encountered over a period of 20 years. METHODS: The medical records of 56 patients diagnosed with DBA were retrospectively reviewed from November 1984 to July 2010. Fifteen institutions, including 13 university hospitals, participated in this study. RESULTS: The male-to-female ratio of patients with DBA was 1.67:1. The median age of diagnosis was 4 months, and 74.1% were diagnosed before 1 year of age. From 2000 to 2009, annual incidence was 6.6 cases per million. Excluding growth retardation, 38.2% showed congenital defects: thumb deformities, ptosis, coarctation of aorta, ventricular septal defect, strabismus, etc. The mean hemoglobin concentration was 5.1+/-1.9 g/dL, mean corpuscular volume was 93.4+/-11.6 fL, and mean number of reticulocytes was 19,700/mm3. The mean cellularity of bone marrow was 75%, with myeloid:erythroid ratio of 20.4:1. After remission, 48.9% of patients did not need further steroids. Five patients with DBA who received hematopoietic transplantation have survived. Cancer developed in 2 cases (3.6%). CONCLUSION: The incidence of DBA is similar to data already published, but our study had a male predilection. Although all patients responded to initial treatment with steroids, about half needed further steroids after remission. It is necessary to collect further data, including information regarding management pathways, from nationwide DBA registries, along with data on molecular analyses.
