Background :Complementary and alternative medicine (CAM) is now being increasingly used among cancer patients. The objectives of our study were to assess the prevalence, types, cost, subjective effects, and side effects of CAM use, reasons for CAM use, characteristics of CAM users compared to those of nonusers, and patients’ expectations of doctors regarding their CAM use among Korean cancer patients at a single cancer center.Methods :From April to August, 2003, we interviewed 186 cancer patients hospitalized in the Korea Cancer Center Hospital using a structured questionnaire, and analyzed the data.Results :78.5% of experimental subjects (146 patients) had been treated with at least one type of CAM, in addition to conventional Western treatment, with a mean monthly cost of 1,380,000 Won/person (approximately, 1,100 U.S. dollars on July, 2004). The most prevalent types of CAM used by these patients included medicinal mushrooms (67.1%), herbs (54.1%), vegetable diets (50.6%), and ginseng (46.5%). The main reported reasons for the use of CAM in addition to conventional medicine were nutritional support (19.1%) and physical strengthening (17.8%). 5% of CAM users experienced side effects. The younger and more educated the patients were, the more likely they were to employ CAM. 66% of CAM users wanted to discuss CAM techniques with their doctors.Conclusion :More than two-thirds of cancer patients used various kinds of CAM, incurring considerable costs. Therefore, in order to help patients make informed decisions, medical society should be open to communication with patients. Not only the scientific aspects, but also the economic aspects of CAM usage should be examined more thoroughly, in order to ensure proper distribution of medical resources.

Background/Aims: Halitosis is a symptom that bothers patients more socially than medically and its pathogenic mechanisms are unclear and treatment armamenterium is limited. Clinicians generally ignored active interventions. Since halitosis is closely associated with volatile sulfur compounds (VSCs), we used a Halimeter and gas chromatography to measure VSCs in patients with Helicobacter-pylori (H. pylori)-associated gastric diseases. Methods: We categorized 72 patients with H. pylori infection into two groups based on their endoscopic findings: a nonerosive mucosal group (NE, n=24) and an erosive mucosal group (E, n=48). Halitosis was objectively assessed by applying either a Halimeter to breath air or gas chromatography to gastric juice. Simultaneously, the expression of VSC-generating enzyme was measured with reverse-transcriptase PCR using mRNA isolated from biopsy tissues. Results: The levels of VSCs in exhaled breaths or aspirated gastric juices differed significantly between the NE and E groups (p ＜0.00001), suggesting that VSCs might reflect eroded epithelial damage induced by H. pylori infection. The expressions of cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) were broadly consistent with the degree of mucosal injury. Conclusions: Erosive changes in esophagogastroduodenal mucosa were strongly correlated with increased VSC levels, suggesting that halitosis might result from H. pylori-associated erosive lesions.

Protein-losing enteropathy is the manifestation of a diverse set of disorders, and it is characterized by the excessive loss of plasma proteins into the affected portions of the gastrointestinal tract, and this results in hypoalbuminemia. We report here on a case of severe protein-losing enteropathy with the typical clinical features of hypoalbuminemia, dependent edema and increased alpha 1-antitrypsin (α1-AT) clearance, as measured by using 24hr stool testing. The associated disorder with the protein-losing enteropathy of our case was radiation enterocolitis and lymphatic obstruction that was due to radiation treatment and lymph node dissection in the remote past for the treatment of uterine cervical carcinoma. Our case suggests that chronic radiation enterocolitis can result in irreversible injury to the intestinal mucosa and a protein-losing enteropathy, which can bring about a very poor quality of life and even the loss of life.
