Repeated surgery of the lumbar spine after lumbar discectomy was not uncommon. Total 817 cases of lumbar disorders were carried out surgical intervention in author's clinic from Jan. 1993. to May 1997. Among them, 82 cases were reoperated cases after lumbar disc surgery. The causes, methods and outcome of reoperation were reviewed. The most common causes of reoperation was epidural adhesion, and the most frequent method of reoperation was the interbody fusion with adhesiotomy. Epidural fibrosis was the major problem and must be studied forward for preventing reoperaion.

OBJECTIVES: The purpost of this study was to present general system,operation,and program of a day care model managed by a psychiatrist,to evaluate the results of performing this model,and thus to developa day care model applied to Korean situation appropriately for promoting maintenance and rehabilitation of chronic psychotic patients. METHODS: We performed this day care model(hereinafter called as this model) from March 1997 to February 1998. The subjects were composed of 23 psychotic patients. PANSS, Quality of Life Scale,Life Satisfaction Self-Rating Scale were used before beginning this model-and after three months of performing this model. Program Helpfulness Scale,13 Therapeutic Factors Scale were used at one month of day care and after three months of day care. RESULTS: 1) This model helped maintenance and rehabilitation of chronic psychotic patients through reducing their symptoms and increasing quality of life. 2) This model used the various group therapy, especially creative art therapy and activeity therapy, played an important fole,for recovering Physical,psychological,and social functions. 3) Important therapeutic factors at early and late period of this model were identification with therapists,guidance of therapists,and the corrective recatitulation of the primary family group. Important therapeutic factors at early period were group cohesiveness and altruism, and at late period instillation of hope. 4) This model was useful for integration the multidisciplinary therapeutic team and the various therapeutic methods. CONCLUSION: This model would be applied to day care in this country effectively and efficiently for maintenance and rehabilitation of chronic psychotic patients.

PURPOSE: Hyperventilation during cardiopulmonary resuscitation (CPR) is common and can be detrimental to survival. We designed a method for delivery of an appropriate rate of ventilation during CPR by setting a compression numbers to ventilation ratio. METHODS: We conducted a virtual simulation trial using 12 randomly sorted actual CPR video files. Participants provided ventilation using a self-inflating bag while watching one minute of CPR video clips utilizing pre-set compression to ventilation ratios of 10:1, 12:1, and 15:1, respectively. Ventilation rates per minute were manually calculated and analyzed. RESULTS: Eight medical doctors and eight emergency medical technician students were included. Among the three groups, significant different mean (S.D) ventilation rate per min (compression to ventilation ratio were 10:1, 12:1, and 15:1) was (9.9 (1.3) vs. 8.8 (1.0) vs. 7.2 (0.8), respectively; p<0.0001). Proportion of the number of appropriately delivered ventilations was 62.5%, 89.6%, and 38.0% for compression to ventilation ratios of 10:1, 12:1, and 15:1, respectively (p<0.0001). CONCLUSION: Compression to ventilation ratio of 12:1 resulted in a significantly appropriate ventilation rate, compared with the ratio of 10:1 or 15:1. Pre-set compression to ventilation ratio of 12:1 seems to be a novel method for delivery of an appropriate number of ventilations during CPR after establishment of an advanced airway.

PURPOSE: The aim of the study is to evaluate the clinical usefulness of a TWI in the lead aVL of 12-lead ECG for predicting the left ascending artery (LAD) lesion, high risk, and 30-days mortality in patients with acute coronary syndrome (ACS). METHODS: A total of 275 patients who underwent coronary angiography under the diagnosis of ACS were analyzed retrospectively from Jan 2012 to December 2013. RESULTS: A total of 355 patients underwent coronary angiography. Of these, 275 patients (77.5%) were diagnosed with ACS. Of these, 187 patients (68.0%) had a left LAD lesion. Of these, 111 patients (59.3%) had a mid-LAD lesion. Of these, only 23 patients (22.5%) showed a TWI in the aVL lead. However, regarding the prediction of the high risk group, if there is a TWI in the aVL, when compared with patients without a TWI in the aVL, the high risk rate is four times higher in the univariable logistic regression analysis and 2.687 times higher in the multivariable logistic regression analysis. CONCLUSION: A TWI in the lead aVL of ECG of patients with chest pain in the ER was closely associated with high risk of ACS patients.

PURPOSE: Due to their vulnerability and relatively high driving speed, motorcycles have been associated with a high risk of sustaining multiple severe injuries after traffic accidents. We sought to investigate sustained injuries and the association of accident mechanisms with injury severity for unhelmeted motorcycle accident victims. METHODS: This study was conducted as an observational retrospective study. Unhelmeted motorcycle accident victims who visited the study hospital from January 2010 to December 2011 were included. Data were obtained from medical records, ambulance run-sheets, and telephone interviews. Accident mechanisms were divided into collision with an obstacle, single vehicle accident, collision with another vehicle, collision by another vehicle, and falling accident from the viewpoint of energy. Glasgow coma scale (GCS), Revised trauma score (RTS), and Injury Severity Score (ISS) were analyzed for comparison of injury severity according to the accident mechanisms. RESULTS: Of 404 patients who visited the study hospital, 165 patients were included; 87.3%(144/165) were male, and 78.8%(130/165) were drivers. The incidence of motor cycle accident showed the highest in the teenager and in time during 18:00~24:00 o'clock. Lower extremity was the most common site of injury, followed by upper extremity, head, and face etc. Injury due to falling was the most severe injury mechanism, followed by collision with another vehicle, collision by another vehicle, and a single vehicle and an obstacle (p=0.013). CONCLUSION: Lower extremity injury was the most common injury site in unhelmeted motorcycle accidents, and motorcycle accidents by fall and collision with another vehicle should be considered as a severe mechanism of injury.

BACKGROUND: Fluoroquinolone drugs are an important anti-tuberculous agent for the treatment of multi-drug resistant tuberculosis. However, many drugs belonging to the fluoroquinolones have different cross resistance to each other. METHODS: Sixty-three ofloxacin (OFX) resistant and 10 pan-susceptible M. tuberculosis isolates were selected, and compared for their cross resistance using a proportion method on Lowenstein-Jensen media, containing ofloxacin (OFX), ciprofloxacin (CIP), levofloxacin (LVX), moxifloxacin (MXF), gatifloxacin (GAT) and sparfloxacin (SPX), at concentrations ranging from 0.5 to 3microgram/ml. DNA extracted from the isolates was directly sequenced after amplifying from the gyrA and gyrB genes. RESULTS: The 63 OFX resistant M. tuberculosis isolates showed complete cross resistance to CIP, but only 90.5, 44.4, 36.5 and 46.0% to LVX, MXF, GAT, and to SPX, respectively. Fifty-one of the isolates (81.0%) had point mutations in codons 88, 90, 91 and 94 in gyrA, which are known to be correlated with OFX resistance. The Gly88Ala, Ala90Valand Asp94Ala mutations in gyrA showed a tendency to be susceptible to MXF, GAT and SPX. Only 4 isolates had mutations in the gyrB gene, which did not affect the OFX resistance. CONCLUSION: About 60% of the OFX resistant M. tuberculosis isolates were susceptible to GAT, SPX and MXF. These fluoroquinolones may be useful in the treatment of TB patients showing OFX resistance.
