Maritime Remote Medical Advice Performed by Emergency Medical Information Center in South Korea

PURPOSE: Seafarers injured at sea need appropriate and prompt medical advice. Since 2002, the Busan emergency medical information center (BEMIC) has provided remote medical advice to vessels on the distant ocean via telephone, e-mail, facsimile and radio-transmission. METHODS: Seventy-four cases had requested remote medical advices to BEMIC from Jan 2005 to Jul 2005, and they were studied retrospectively. We analyzed patients' general characteristics, type of disease or injury, dispositions, and so forth. The cases were classified into three groups according to disposition. Class I was defined as a case which required simple treatment. Class II involved medical or surgical treatment with close observation. Class III required transfer to the nearest harbor instantly due to severe or uncertain condition. RESULTS:The nationalities of subjects were Korean (32.4%), Southeast Asians (35.1%), Chinese (24.3%) and others. The most common symptom was abdominal pain (24.3%). The patients'disease types were acute disease (53.4%), trauma (20.3%), burn (13.7%), chronic disease (8.2%) and others. There were 8 voluntary medication cases, which were performed by seamen before taking medical advice. The dispositions were class I (6.8%), class II (39.7%), and class III (53.5%), respectively. A cross-sectional study between the types and the dispositions was performed, revealing a statistical significance (p<0.001). CONCLUSION: Despite the lack of any kind of direct support from ship companies or governments, the remote medical advice service has performed. Enhancing educational programs based on this data is necessary in order to provide effective education of seafarers.

Cord-like Atresia of the Abdominal Aorta Due to Takayasu Arteritis in Middle Aged Woman: A case Report / 대한흉부외과학회지

Takayasu arteritis is a chronic non-specific inflammatory arteriopathy that involves primarily the first branches of aortic arch but may also affect the aorta and any of its primary branches. A characteristic trait of the disease is that most of the patients are young females of mainly Asian and South American origin. Recently, we experienced a rare case of Takayasu arteritis which showed a cord-like atresia of abdominal aorta just below renal arteries in 52-year-old woman. We performed a side to side bypass graft from descending thoracic aorta to abdominal aorta just above the aortic bifurcation with a 18mm PTFE(polytetrafluoroethylene) vascular graft. The postoperative course was uneventful.

Role of Crural Diaphragm after Esophagogastrectomy / 대한흉부외과학회지

BACKGROUND: The high pressure zone(HPZ) at the gastroesophageal junction is an important barrier for prevention of gastroesophageal reflux. Smooth muscle layers in the lower esophageal sphincter mainly contributes to HPZ at the throacoabdominal junction. The purpose of this study was to investigate the manometric characteristics of the thoracoabdominal junction in patients after surgical removal of the lower esophageal sphincter. MATERIAL AND METHOD: Twenty two patients with prior esophagogastrectomy(10 Ivor-Lewis method and 12 left thoracotomy) and 30 normal adults(control group) were studied manometrically. RESULT: Esophageal manometry showed a HPZ and pressure inversion point distal to the anastomosis in 12 of 22 patients(2 of 10 patients with Ivor-Lewis method and 10 of 12 patients with left thoracotomy) and a HPZ in 30 of 30 normal adults. The location of HPZ from nostril was not significant different between the two groups(42.5+/-0.9cm in patients and 43.9+/-2.1cm in the control), while the length of HPZ was shorter in patients than in the control(2.13+/-0.6cm vs 2.83+/-0.59cm). By SPT and RPT, pressures of HPZ at rest were lower in patients(13.78+/-1.63mmHg, 28.58+/-6.06mmHg) than in control(20.3+/-4.95mmHg, 42.80+/-15.91mmHg). The HPZ relaxed partially in response to deglutition(84.4% in patient, 90.5% in control group) and contracted in response to increased intra- abdominal pressure induced by leg lifts(HPZ/ Intra-abdominal pressure= 1.81+/-0.23 in patient, 2.13+/-0.58 in control group). CONCLUSION: This study shows an HPZ at thoracoabdominal junction after surgical removal of the lower esophageal sphincter. It may be important to perform a crural myoplasty during esophageal reconstruction after esophagogastrectomy because crural diaphragm acts as sphincter like HPZ at the thoracoabdominal junction.
