To evaluate the neurologic and functional improvement of anterior decompression and fusion in patients with cervical spin injury, the clinical records and x-rays of 17 patients who were treated at Gyeong-Sang National University Hospital between January 1989 and December 1993 were analyzed. The results were as follows 1. There were complete injuries of the cord in six cases, incomplete injuries in nine and nerve root injuries in two. All the patients were treated using anterior decompression and autogenous iliac bone graft with cervical plate fixation within 7 days after trauma. 2. The average time lapse from the operation to radiological union was 9.2 weeks(range;7–14 weeks). 3. The prognosis for neurologic recovery mainly depends on the severity of the initial neurologic status. The recoveries of neurologic deficit were complete in four cases, partial in ten and none in three. The motor index improved from 45.6 to 64.6 and the modified Barthel index was 71.2 points at the last follow-up. 4. The clinical results were excellent in nine cases, good in three, fair in two and poor in three. In conclusion, anterior decompression and fusion with bone graft and cervical plate provided early mobilization and rehabilitation, and improved neurological function in a considerable portion of the patient who had neurologic deficits after cervical spine injuries.

PURPOSE: High flow rate (FR) and pressure limit (PL) strategy with time-cycled pressure-limited (TCPL) ventilator is employed routinely in the neonates. Theoretical basis of this strategy is the two-compartment theory that the lung with acute respiratory failure consists of units with different compliance and resistance. But such constant pressure strategy has the risk of ventilator induced lung injury. We compared the ventilatory indices and clinical outcomes of two different strategies, high FR-constant pressure and low FR-constant FR in the ventilator care of the neonates with acute respiratory failure. METHODS: For the neonates born in our hospital and treated with mechanical ventilation from March to August in 1997, two different ventilator strategies were employed randomly with flow control ventilator. In the high-FR group, the FR was fixed at 10 L/ min and the PL was adjusted according to the arterial blood gas analysis (ABGA) results. In the low-FR group, the FR was adjusted to 10 mL/kg of tidal volume. Sixty neonates were enrolled, 32 in high-FR and 28 in low-FR group. Ventilatory indices and clinical outcomes were statistically cornpared in the two groups. RESULTS: Perinatal factors were not different in the two groups. Initial ventilator settings, ABGA results and ventilatory indices were not different. The tidal volume, fraction of inspired oxygen, peak inspired pressure and oxygenation index were higher and dynamic compliance was lower in the high-FR group compared to the low-FR group after 3 to 72 hours of ventilator care. In clinical outcomes, incidences of pulmonary interstitial emphysema, pneumothorax and chronic lung disease were significantly lower in the low-FR group. CONCLUSION: Low-FR with constant FR strategy resulted in better clinical outcomes in the ventilator care of neonates. We conclude that constant FR strategy prevents damage of the better compliant lung units and decreases the incidence of acute and chronic complications of ventilator care.

PURPOSE: Smoking is the leading cause of death and smoking initiation rarely occurs after adolescence. Thus research on adolescent smoking is crucial. A consistent definition of smoking is important because inconsistent definitions make comparisons across studies an arduous task. Thus, the aim of the study was to suggest future research directions for smoking definitions after examining pitfalls in the literature. METHODS: In this study the literature on adolescent smoking in the U.S. and South Korea was examined, and three types of smoking definitions were identified. Limitations in the studies are identified and future research directions are suggested. RESULTS: In the U.S. literature, smoking definitions can be categorized into three groups: definitions based on stage models, smoking trajectories, and definitions derived from specific data. In the South Korean literature, various levels of smoking have not been differentiated. CONCLUSIONS: While the literature does not provide a definitive answer regarding the definition of smoking, it suggests three issues to consider for future research. First, multiple measures of smoking are more desirable than a one-time measure. Second, theory- or trajectory-based smoking definitions are more desirable than definitions derived from available data. Finally, regularity and amount of cigarette use should be incorporated in defining smoking behavior.

The coding and filing of pathologic diagnoses have been heavy tasks; however with the availability of inexpensive microcomputer, a system may be developed that permits storage and retrieval to be performed efficiently. With Apple II(R) computer system and SNOP coding, a simple program using dBASE-II and QUICKCODE computer program can be created to include the following informations: accession number, chart number, sex and age of patients and 2 diagnosis codes. Once SNOP coding is carried out by medical staff, a secretary or clerk can enter the informations into the microcomputer. Data may be searched on any combination of the above parameters.

PURPOSE: This study aims to assess the effects of psychosocial work environment and self-efficacy on stress, depression, and burn-out among office workers. METHODS: Survey data were collected from 331 office workers who worked in one workplace from April 10 to 30, 2012. The impact of psychosocial work environment and self-efficacy on stress, depression, and burn-out was analyzed with hierarchical multiple regression using SAS version 9.3. RESULTS: Work-family conflicts and emotional demands were identified as main factors influencing mental health. Other work environment factors influencing mental health were role clarity for stress, possibilities for development, meaning-of work, social support-from supervisors and job insecurity for depression, and social community at work for burn-out. Self-efficacy was correlated with most psychosocial work environment and factor with independent influence on stress and depression. The final models including general characteristics, psychosocial work environment, and self-efficacy accounted for 34%, 44%, and 36% for stress, depression, and burn-out respectively. CONCLUSION: To promote mental health in office workers, there is a need to decrease work-family conflicts and emotional demands and to improve work organization and job contents, social support, and self-efficacy.

We report a patient who developed a Barrett,s esophageal ulcer 10 years after esophagomyotomy for achalasia. A-59-year-old female was admitted to the hospital with dysphagia for 2 months. In 1982, she had undergone a modified Heller esophagomyotomy for achalsia. After esophagogram, esophageal manometry, 24hr esophageal pH monitoring, esophagoscophy achalasia and Barrett,s esophageal ulcer was diagnosed. So, she had been treated with omeprazole and sucralfate and has been followed up in a asymtomatic state currently. In Barrett,s esophagus, there is a metaplasia of the normal stratified squamous mucosa to columnar epithelium, caused by the reflux of acid. It appears in approximately 10% of patients with chronic gastroesophageal reflux and is associated with increased probability of adenocarcinoma of the esophagus. Among the predis- posing factors of gastroesophageal reflux, there is treatment of esophageal achalsia by forceful dilatation or by the esophagomyotomy. The resultant ralaxation of lower esophageal sphinter, combined with deficient propulsive esophageal peristalsis, predisposed to gastroesophageal reflux. Actually an increased incidence of gastroesophageal reflux, esophagitis and stricture are well-known complications after esophagomyotomy. But in spite of higher risk of gastroesophageal reflux after esophagomyotomy the development of Barrett,s mucosa has been rarely reported and only recently recognized. Diagnosis of Barrett,s esophagus in such patients is difficult and the cumulative effects of achalasia and Barrett's esophagus predispose these patient to higher risk of developing esophageal carcinoma. So, high index of awareness and regular endoscopic surveillance are required.
