AIM: To determine the prevalence and risk factors of work-related musculoskeletal disorders in gastrointestinal endoscopists in Korea. METHODS: A survey of musculoskeletal symptoms, using a self-administered questionnaire, was conducted on 55 endoscopists practicing in general hospitals or health promotion centers. RESULTS: Forty-nine (89.1%) endoscopists reported musculoskeletal pain on at least one anatomic location and 37 (67.3%) endoscopists complained of pain at rest. Twenty-six (47.3%) endoscopists had severe musculoskeletal pain defined as a visual analogue score greater than 5.5. Factors related to the development of severe pain were (1) standing position during upper endoscopy, (2) specific posture/ habit during endoscopic procedures, and (3) multiple symptomatic areas. Finger pain was more common in beginners, whereas shoulder pain was more common in experienced endoscopists. Sixteen percent of symptomatic endoscopists have modified their practice or reduced the number of endoscopic examinations. Only a few symptomatic endoscopists had sought professional consultation with related specialists. CONCLUSION: The prevalence of musculoskeletal pain in endoscopists is very high. The location of pain was different between beginners and experienced endoscopists. Measures for the prevention and adequate management of endoscopy-related musculoskeletal symptoms are necessary.

Primary adenocarcinoma of the appendix is a rare malignancy that constitutes 〈 0.5% of all gastrointestinal neoplasms. Moreover, primary signet ring cell carc noma of the appendix is an exceedingly rare entity. We have encountered 15 cases of primary appendiceal cancer among 3389 patients who underwent appen- dectomy over the past 18 years. In the present report, we describe a rare case of primary signet ring cell carcinoma of the appendix with ovarian metastases and unresectable peritoneal dissemination occurring in a 67-year-old female patient. She underwent ap- pendectomy and bilateral salpingo-oophorectomy with a laparoscopy procedure. She then received palliative systemic chemotherapy with 12 cycles of oxaliplatin, 5-flurorouracil, and leucovorin （FOIFOX-4）. The patient currently is well without progression of disease 12 mo after beginning chemotherapy.

Protective effects of electroacupuncture on acetylsalicylic acid-induced acute gastritis in rats

引用

World Journal of Gastroenterology 2009年第8期15卷 973-977页

作者： hye Suk hwang Kyung-Ju Han Yeon Hee Ryu Eun Jin Yang Yoo Sung Kim Sang Yong Jeong Young-Seop Lee Myeong Soo Lee Sung Tae Koo Sun-Mi Choi Department of Medica Research Korea Institute of Oriental Medicine Daejeon 305-811 South Korea Division of Meridian and Structural Medicine School of Oriental Medicine Pusan National University Pusan 609-735 South Korea

AIM: To investigate the protective effects of electroacupuncture (EA) pretreatment on acetylsalicylic acid (ASA)-induced ulceration in rats. METHODS: We randomly divided 72 rats into three groups including control (administered with distilled water), ASA group (administered 100 mg/kg ASA) and EA group (administered EA + 100 mg/kg ASA). Each rat was fasted for 18 to 24 h before experimentation, and lesion scores, gastric acidity, cyclooxygenase (COX)-1 and -2 mRNA levels, and total nitric oxide (NO) concentration were measured. RESULTS: The lesion scores of the EA group were significantly lower than those of the ASA group. Gastric acidity of the ASA and EA groups was reduced compared to the control group. COX-1 and -2 mRNA levels were significantly increased in the EA group as compared to the control and ASA groups, and NO levels were also significantly increased in the EA group as compared to the ASA group. CONCLUSION: These results suggest that EA-mediated protection against ASA-induced ulceration in rats may occur via gastric defense components.
