PURPOSE: The out-of-hospital cardiac arrest (OHCA) survival rate of patients in Korea is lower than the global average and it might be caused by an extremely low rate of return of spontaneous circulation in the prehospital field. The authors identified obstacles that disturb on-scene performance of cardiopulmonary resuscitation (CPR) for a certain period from 119 emergency medical technicians (EMTs) through a nation-wide paper survey. METHODS: A total of 1273 first grade EMTs and nurses were surveyed. CPR time performed on the scene (without transfer), CPR experiences, self-assessment of CPR skill performance, and both obstacles to performance of CPR on the scene and solutions to overcoming them for continuous on-scene CPR were investigated using a 28-item questionnaire. RESULTS: The average for work experience and the number of CPR experiences of subjects was 6.8+/-4.5 years and 1.9+/-1.7 times/month, respectively. Survey results for CPR times on the scene showed an average of 4.2+/-2.4 minutes, approximately two periods of CPR (30:2x5 cycles). Obstacles to CPR on the scene were investigated as complaints of family members in 791(62.1%) and fatigue lowering CPR quality due to lack of human resources in 536(41.0%); 627(49.3%) of the subjects answered that they had received complaints due to a long stay on the scene. CONCLUSION: In order to increase the survival rate of OHCA patients, CPR on the scene is needed during a certain period in order to achieve a return of spontaneous circulation. Education, amelioration of guidelines, and support for the EMT administrative system are also needed.

OBJECTIVE: Analyses of the status of 119 emergency situation control center (119 ESCC) usage are lacking. Therefore, this study investigated the status of the 119 ESCC usage, including dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) instructions. METHODS: The emergency activity daily reports and emergency instruction sheets of 119 ESCC from January to December 2016 were reviewed. For more accurate status analysis, the computerized data of the 1339 Emergency Medical Information Center from January to December 2011 were also reviewed. RESULTS: In 2016, the total usage of the 119 ESCC was 1,393,876 calls, which was 27.8% lower than the 1,930,977 calls in 2011. Of the 1,393,876 eligible calls, the most common call was hospital guidance (n=743,799, 53.4%), followed by first aid (n=397,620, 28.5%), disease consultation (n=150,128, 10.8%), medical oversight (n=81,174, 5.8%), and interhospital transfer (n=5,123, 0.4%). Regarding the user number per 10,000 persons, Daejeon was the greatest at 57.2, whereas Changwon was the lowest at 11.5. A total number of DA-CPR was 19,439. The time from the call to chest compression were 173±88.6 seconds in the subjects having previous cardiopulmonary resuscitation training and 184.0±88.2 in the subjects having no such training (P < 0.001). CONCLUSION: The ratio of first aid instructions, including DA-CPR, among total usage of the 119 ESCC increased but the overall usage of the 119 ESCC decreased. Therefore, further efforts will be needed to improve the quality and professionality of the information provided through the operation of 119 ESCC.

Schwannomas are benign neoplasms arising from the sheath of myelinated nerve fibers and may occur in any part of the body. They mostly occur in the head and neck region, accounting for about 25% to 45% of all cases. The eighth cranial nerve is the most common site of origin. About 4% of all head and neck schwannomas originate in the nasal cavity and paranasal sinuses. The best treatment of schwannomas is surgical excision. Since it is an encapsulated tumor, difficultly is rarely encountered in its complete removal, and recurrence is unlikely. We present a unique and rare case of a 71-year-old man with a recurrent septal mass, finally diagnosed as a schwannoma, with a review of the literature.

BACKGROUND: Burn is one of the most common illness in primary care. Most burns are partial skin thickness burns. The purpose of this study was to evaluate the use ofSilvadene (silver sulfadiazine) ointment (antibacterial agent) and DuoDERMR (artificial syntheticmaterial). METHODS: The subjects of this study were 46 patients with partial skin thickness burns who had visited a general hospital burn clinic from May 1, 2002 to June 30, 2002. They were randomly assigned to the silvadine ointment or DuoDERMR group. The patients were evaluated for pain, the number of dressing change, the ease of dressing application and removal, limitation of activity, comfortableness, satisfaction with the appearance, sleep disturbance, treatment cost, and the number of days for complete epithelialization. RESULTS: DuoDERMR treated burns had a fewer dressing change (3.19 times vs 5.36 times), less time for dressing change (4.13 min vs 6.26 min) and less cost (P<0.01). But there was no statistical difference in the number of days for complete epithelialization (P=0.197) and it depended on the size of the wounds (P=0.005). The cost of treatment was related with the number of dressing change (P=0.000). CONCLUSION: Treatment methods had no effect on duration of treatment but artificial synthetic material was shown to reduce the time for dressing and the cost.

The laryngeal granuloma (LG) is non-neoplastic lesion that mainly develops in the posterior vocal folds. It is welknown that mis- or overuse of voice, habitual coughing, and endotracheal intubation can become the cause of LG. The laryngopharyngeal reflux also comes into the spotlight as an etiologic factor. Although LG has a tendency to recur easily, it is not a premalignant lesion. The co-existence with granuloma and laryngeal cancer has not been reported earlier. Recently, we encountered a 72-year-old man with a posterior glottic mass, which was diagnosed as squamous cell carcinoma coexisting with granuloma. To our knowledge, this is a first report on two coexisting carcinomas in the glottis.

PURPOSE: To evaluate the effectiveness of a cycloplegic regimen using 0.5% tropicamide and 0.5% phenylephrine (Tropherine, Hanmi Pharm), in addition to 1% cyclopentolate, in hyperopic children. METHODS: The medical records of hyperopic patients below the age of 14 years who had undergone cycloplegic retinoscopy were retrospectively reviewed. Cycloplegic refractions were performed using one of two cycloplegic regimens. Regimen 1 was a Tropherine-added regimen comprising the administration of one drop of 1% cyclopentolate followed by two to three drops of Tropherine added at 15-minute intervals. Regimen 2 was a cyclopentolate-only regimen comprising the administration of three to four drops of 1% cyclopentolate at 15-minute intervals. The mean difference between noncycloplegic and cycloplegic refraction was compared between the two regimens. RESULTS: A total of 308 eyes of 308 hyperopic children were included. The mean difference (±standard deviation) in the spherical equivalent (SE) between cycloplegic and noncycloplegic refraction was significantly larger in regimen 2 than in regimen 1, with values of +1.70 ± 1.03 diopters (D) and +1.25 ± 0.89 D, respectively (p=0.001). The SE change after cycloplegia was significantly different between the two regimens only in patients aged 5 years or younger (p=0.001), particularly in those with high hyperopia with an SE ≥5 D (p=0.005) or fully accommodative esotropia (p=0.009). There was no significant difference between the two regimens in patients older than 5 years, regardless of the presence of high hyperopia or fully accommodative esotropia. CONCLUSIONS: The Tropherine-added regimen exerted a weaker cycloplegic effect than the cyclopentolate-only regimen, particularly in children under the age of 5 years with high hyperopia or fully accommodative esotropia. However, the difference in refraction between the two regimens was small. A Tropherine-added regimen can be effective in hyperopic children, with less associated discomfort than the instillation of cyclopentolate.

Hemoptysis is a common complication of pulmonary tuberculosis. Most of the cases of hemoptysis originate from hypertrophied bronchial arteries. Also, diabetes induces pulmonary vascular abnormalities such as endothelial dysfunction, inflammatory infiltration and pulmonary vascular remodeling. A 27-year-old male, with diabetes and a history of tuberculosis, underwent the procedure of pars plana vitrectomy under general anesthesia. After an uneventful intra-operative period, he had hemoptysis prior to extubation. Emergency fiberoptic bronchscopy showed blood plugs and spotted fresh blood at the right upper lobar bronchus. After successful embolization of the bronchial artery, the patient made a recovery and was discharged without experiencing any complication. Predisposing factors of hemoptysis in this case are presumed to be tuberculosis and diabetes. The bleeding might had been caused by the rupture of a weakened artery within the cavity in the right upper lobe, through expansion of the lung during manual ventilation by positive pressure.

OBJECTIVE: To evaluate the complication and recurrence rates in patients undergoing trocar-guided mesh implant for pelvic organ prolapse (POP) treatment. METHODS: A retrospective study was performed based on the medical records of patients who had undergone mesh implant by one surgeon from May 2006 to August 2013 at the Presbyterian Medical Center in Korea. We evaluated perioperative complications such as bladder injury, mesh exposure, urinary symptoms, infections, and chronic pelvic pain. Recurrence was defined as a POP-quantification system stage ≥II or any symptomatic prolapse. RESULTS: Sixty-seven patients were evaluated, and the mean age of patients was 65.4±7.2 years. Stage ≥III POP-quantification Ba was noted in 61 patients (91%). Intraoperative complications included three cases of bladder injury (4.5%). The mean follow-up period was 44.1±7.9 months. Postoperative complications occurred in seven women (10.5%): four cases of urinary symptoms (6%), two cases of infections (3%), and one case of chronic pelvic pain (1.5%). Mesh exposure did not occur (0%). Prolapse recurrence was reported in five patients (7.5%). CONCLUSION: Based on our operational result, the trocar-guided mesh implant seems to provide safe and effective outcomes.

BACKGROUND: Factors associated with the prognosis of patients with small cell lung cancer (SCLC) is relatively unknown, than of those with non-small cell lung cancer. This study was undertaken to identify the prognostic factors of SCLC. METHODS: The medical records of 333 patients diagnosed with SCLC at tertiary hospital from January 1, 2008, to December 31, 2012 were retrospectively reviewed. Patients were categorized by age (≤65 years vs. >65 years) and by extent of disease (limited disease [LD] vs extensive disease [ED]). Overall survival and progression free survival rates were determined. Factors associated with prognosis were calculated using Cox's proportional hazard regression model. RESULTS: Most baseline characteristics were similar in the LD and ED groups. Eastern Cooperative Oncology Group (ECOG) performance status (PS), first chemotherapy regimen, and prophylactic cranial irradiation (PCI) differed significantly in patients with LD and ED. Mean ECOG PS was significantly lower (p<0.001), first-line chemotherapy with etoposide-cisplatin was more frequent than with etoposide-carboplatin (p<0.001), and PCI was performed more frequently (p=0.019) in LD-SCLC than in ED-SCLC. Prognosis in the LD group was better in younger (≤65 years) than in older (>65 years) patients, but prognosis in the ED group was unrelated to age. CONCLUSION: This study showed that overall survival (OS) was significantly improved in younger than in older patients with LD-SCLC. Univariate and multivariate analyses showed that age, PCI and the sum of cycles were significant predictors of OS in patients with LD-SCLC. However, prognosis in the ED group was unrelated to age.
