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.

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.

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.

Human papillomavirus(HPV) has implicated in the development of cervical cancer. Several studies has suggested a strong correlation between HPV 16, 18 and cervical intraepithelial neoplasia(CIN). For detecting and typing HPV DNA in cervical tissues, recently the chemiluminescent molecular hybridization assay method has been widely used. This study was performed to determine the usefulness of hybrid capture assay for detecting high-risk HPV in cervical epithelial cells, and to compare the correlation among cervical cytology, biopsy finding and HPV infection, and to determine whether the addition of the hybrid capture assay to cytologic test would improve the ability to identify significant lesions. This study included 267 patients who visited the colposcopic clinic of the department of obstetrics and gynecology, Chonbuk University Hospital from May, 1997 to October 199S. Pap smears hybrid capture assays, and colposcopically directed biopsy were performed concurrently on al1 women. The results obtained were as follow; l. Using hybrid capture assay, the detection rate of high-risk HPV of all patients was 37.1%(99/267). There was no statistical significance in the detection rate of HPV between the age groups. 2. The false negative rate of Pap Smear was 53.3% and showed significant discrepancies between the cytologic and histologic diagnosis. 3. According to the cytologic diagnosis, the detection rates of high-risk HPV were 7.1% in normal, 25.3% in ASCUS or LSIL, and 61.6% in HSIL. In each cytologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 4. According to the histologic diagnosis, the detection rates of high-risk HPV were 0.1% in normal, 11.1% in CIN I, and 72.7% in CIN II or CIN III. In each histologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 5. According to the comparison of histologic diagnosis between positive and negative results of high-risk HPV test due to each cytology, there was no statistical significance in the incidence rate of cervical neoplasia, Above results suggest that high-risk HPV test using hybrid capture assay may be a useful method in supplement the pitfalls of cervical cytology. This test might also have prognostic value in the management of patients with CIN.

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.

PURPOSE: To evaluate the prognostic importance of age in patients with Stage IB cervical cancer, we examined the relationship between age and survival in patients. METHODS AND MATERIALS: Retrospective analysis was performed on 107 patients were treated with surgery followed by postoperative radiotherapy or radiation alone between October 1983 and August 1993 and 28 patients with Stage IB cervical cancer treated with surgery alone between January 1989 and August 1993 at Inje University Seoul Paik Hospital. Patients ranged in age from 26 to 74 (median 48) and were followed for a median period of 39 months. Patients were divided into two groups; Group A comprising 32 patients with< or=age 40 and Group B comprising 75 patients with>age 40. Both Group A and Group B patients were comparable with respect to all covariables studied. RESULTS: The overall 5-year survival and the disease free 5-year survival for the 107 patients studied were 85.2% and 82.1% respectively. The overall survival for group A and Group B was 92% and 83%, respectively(p>0.05). The disease free 5-year survival for Group A and Group B was 82.3% and 82.6%, respectively(p>0.05). There was no difference in both local and distant failure in Group A and Group B. CONCLUSION: On the basis of the this analysis it is concluded that age alone is a poor indicator of prognosis and should not be used as an indication for adjuvant treatment.

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.

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.

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.
