A 19-year-old man had a good neurologic recovery from a severe hypothermia(19 degrees C) and a prolonged coma following active infernal rewarming. From inhaling hydrocarbons, he was left unconscious on the cold floor for 24 hours. As soon as the patient was brought into the emergency medical center, he was early evaluated arid treated aggressively. ECG showed Osborn(J) wave on all leads. The temperature o( patient was increased by 2-3 degrees C per hour through active external rewarming (by heating blankets and warm bag) and active infernal rewarming (by airway rewarming, warmed IV fluids, gastrointestinal tract irrigation, and bladder irrigation). The temperature reached 36 degrees C after 6 hours. Active infernal rewarming provides rapid core rewarming with the additional benefit of circulatory support during the period of cardiac instability.

STUDY OBJECTIVE: determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a religious mass gathered ceremony. DESIGN: Standard charts and a four-tiered triage system(minor, moderate, urgent, and emergent) were developed before the event. The triage system was applied to each chart retrospectively by a single emergency physician. SETTING: Medical staff(10 physicians,13 nurses,1 pharmacist, and 54 first-aid attendants) were based in 8 advanced life support (ALS) clinics. INTERVENTIONS: First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue. Three ambulances were stationed at the venues. RESULT: 22 trauma patients were developed and 183 medical complaints were encountered. Only 7 urgent medical problems were encountered.

An anastomosis stricture with a total obstruction is rare and treatment options are variable. We describe our experience with a combination of a single port transanal laparoscopic approach and intraoperative colonoscopic balloon dilatation. The patient was a 48-year-old man with rectal cancer. A laparoscopic single port lower anterior resection and diverting ileostomy were performed followed by a colon study and ileostomy takedown. The colon study and sigmoidoscopy revealed total obstruction of the rectum at the anastomosis level. We employed a transanal approach using a single port to correct this. We located the anastomosis stricture site and generated a lumen using a dissector and electocautery method to insert the balloon device. Colonoscopic balloon dilatation was subsequently successful. The patient was discharged with no postoperative complications. A laparoscopic single port transanal approach with an intraoperative colonoscopic balloon dilatation is a viable alternative approach to treating an anastomosis stricture of the rectum.

Purpose:
Single-incision laparoscopic surgery is a recently developed minimally invasive surgical technique. We aimed to compare the feasibility and safety of single-incision plus one port laparoscopic low anterior resection (S+1-LAR) with those of multi-port laparoscopic low anterior resection (M-LAR) for mid-to-low rectal cancer.
Methods:
We retrospectively reviewed patient characteristics and surgical outcomes by assessing data collected from the medical records of patients who underwent elective laparoscopic low anterior resection for mid-to-low rectal cancer at the Gangneung Asan Hospital.
Results:
From April 2015 to April 2019, 52 patients underwent S+1-LAR (n=28) or M-LAR (n=24) for midto-low rectal cancer at Gangneung Asan Hospital. There were no significant between-group differences in clinical characteristics. The mean postoperative 1-day pain score was significantly lower in the S+1-LAR group. Surgical outcomes and postoperative complications did not differ significantly between the two groups.
Conclusion
S+1-LAR is a feasible and safe technique and is comparable with M-LAR in terms of surgical outcomes of patients with mid-to-low rectal cancer.

PURPOSE: The purpose of this study was to evaluate the efficacy of contrast-enhanced MR angiography for follow-up examinations after metallic stent placement and to examine the effects of change of imaging parameters used for contrast-enhanced MR angiography. MATERIALS AND METHODS: After four metallic stents (Passager, Ninitol, Wallstent, and Memotherm) were placed in an abdominal aorta shaped vascular phantom, efGRE (enhanced fast gradient recalled echo) 3-D MR angiography was performed, using a 1.5T unit. The four metallic stents were graded 1-3 according to the width and length of their high signal intensity. Variations in the degree of high signal intensity were evaluated according to imaging parameters. RESULTS: The width and length of high signal intensity with the Passager stent and Nitinol stent were greater than with the Wallstent and Memotherm. The larger the field of view, the smaller the matrix number, the larger the flip angle, the greater the width and length of high signal intensity in the metallic stent. CONCLUSION: Contrast-enhanced MR angiography may be a useful follow-up procedure after the placement of Passager and Ninitol metallic stents. The signal intensity of stent lumen varies according to imaging parameters, and the selection of optimal parameters is therefore important.

BACKGROUND: Reperfusion of ischemic myocardium has been postulated to result in a specific oxygen radical mediated tissue injury. Iron may liberate during ischemia and we hypothesized that administration of the iron chelator, deferoxamine during ischemia would result in improved recovery after postischemic reperfusion. PURPOSE: To test whether iron-catalyzed processes contribute to myocardial necrosis during ischemia and reperfusion, deferoxamine was administered to block iron catalyzed hydroxyl radical formation in rabbits. METHODS: Eleven rabbits were divided into two groups: control group (n=5) and deferoxamine pretreatment group (n=6). the left circumflex coronay artery was ligated for 30 minutes and reperfused for 180 minutes. Area at risk (AR) was measured by non-stained area with ethylene blue injection into left atrium after left circumflex coronary artery ligation. Infarct size was measured by weighing after tripheyltetrazolium chloride staining. Heart rate was measured using electrocardiographic recording and systemic blood pressure was monitored by pressure transducer connected to the catheter in the left ventricle. RESULTS: 1. There was no significant difference of heart rate and blood pressure in deferoxamine pretreatment group compared with control group. 2. There was significant decrease of serum iron concentration after continuous infusion of deferoxamine compared with serum iron concentration before ligation of coronary artery (P<0.05). 3. There was no significant difference of area at risk between control and deferoxamine pretreatment group. 4. Area at necrosis to area at risk was significantly reduced in deferoxamine pretreatment group compared with control group (P<0.05) The results suggest that deferoxamine infusion prior to coronary artery occlusion has a significant benefit in reducing infarct size in this model.

On the review of literature, various cases of osteomas orginated from paranasal sinuses can be found. But osteomas which are large enough to produce ocular symptoms are not very common. Even more, various ocular and intracranial sequelae may be complicated from surgical removal of huge frontal osteoma. We present a case of huge frontal osteoma which is originated from frontal sinus and removed successfully without any complications.

We experienced two cases of Boerhaave syndrome (spontaneous esophageal rupture). The first patient was a 62-year-old male who presented epigastric pain after several violent vomitings associated with alcohol ingestion. Diagnosis was done early and promptly in our emergency center and then definitive treatment was done only after 12hrs from onset of his symptom and he was discharged in relatively good condition 256ays after his admission. The second patient was a 44-year-old male who was transfered to our emergency center with chest pain, dyspnea and fever after vomitings associated with autobicycle accident. Diagnosis was delayed due to initial trauma oriented evaluation and incidious develpement of typical clinical findings and then he was managed conservatively but he died of multiple organ failure due to sepsis. We report these cases with literature review.

BACKGROUND: Nitrous oxide is a safe analgesics which has analgesic and sedative effects without loss of consciousness. The advantage of Nitrous oxide is that it has a rapid onset time and that we can modulate duration of its action. The purpose of this experiment is to obtain the safe and effective concentration of Nitrous oxide in Emergency Department as use of analgesics and sedative drugs. METHODS: Twenty volunteers were investigated according to double blind method. Nitrous oxide was administrated to volunteer subjects at different concentrations ; 33%, 50%, 67% each. Then we evaluated the Pain score, Blood pressure, Heart rate, Respiratory rate, Oxygen saturation and its side effects. RESULTS: Pain Score were 8.4+/-2.1 at 33%, 6.1+/-1.5 at 50%, and 3.65+/-2.2 at 67% of Nitrous oxide. Pain Score is decreased significantly following administration of Nitrous oxide at concentration of 50%, 67%(P<0.05). There was no difference between preadministration group and postadministration group. While no remarkable change in systolic blood pressure, heart rate, and oxygen saturation. Respiratory rate showed significant increase when 679o of Nitrous oxide was administrated. There was no side effect in administration of 33% of Nitrous oxide. When 50% of Nitrous oxide was administrated, there were dizziness 5(25%), paresthesia 2(10%), nausea 1(5%), palpitation 1(5%) and hyperethesia 1(5%). At 679o of Nitrous oxide, there were nausea 7(35%), dizziness 6(30%), paresthesia 5(25%), headache 5(25%), diplopia 2(10%), dysphoria 2(10%), salivation 1(5%), dyspnea 1(5%), nystagmus 1(5%), tinnitus 1(5%) and euphoria1 (5%). Incidence of side effect increased as the concentration of Nitrous oxide was increased. CONCLUSION: We can conclude that safe and effective concentration of Nitrous oxide is 50% as analgesics and sedative drugs in the emergency department.
