PURPOSE: The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS: A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS: In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 +/- 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION: Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival.

Interposition arthroplasty of the hip is to create a new joint by interposing an inert and durable substance between the reshapened ends of the femoral head and acetabulum, usually for the treatment of the primary and secondary osteoarthritis of the hip. The major goals of arthroplasty of the hip are to relieve pain, restore joint motion, correct deformity, and to provide stability of the joint. We reviewed the follow-up results of 23 Smith-Patersen vitallium cup arthroplasties in a consecutive series of 20 patients with various arthritides of the hip, who were treated at the National Medical Center between January 1962 and December 1970. Average duration of follow-up was 2 year and 10 months. 1. Male to female ratio was 12:8. Average of the patients was 30 years. 2. Seven patients had rheumatoid arthritis or ankylosing spondylitis and five patients had ankylotic hips. Three patients had primary osteoarthritis and another three osteoarthritis secondary to Legg-Calve-Perthes disease. There were one case each of tuberculous arthritis and traumatic dislocation. 3. Average duration of admission was 7 weeks. 4. Weight bearing was started gradually at 12 weeks post-operatively in majority of the cases. 5. Over-all results of the 20 patients were satisfactory in 12 (60%), and unsatisfactory in 8 (40%). 6. Results of cup arthroplasty in patients with primary osteoarthritis and osteoarthritis secondary to Legg-Calve-Parthes disease were satisfactory in all 6 cases, but were unsatisfactory in 5 out of the 7 cases of the rheumatoid arthritis and ankylosing spondylitis. 7. Three patients with bilateral cup arthroplasties yielded poor results. 8. Complications included eight infections and one each of early dislocation of the cup and periarticular new bone formation.

OBJECTIVES: This study was conducted to compare the characteristics of psychiatric inpatients in mental health related facilities and community mental health services-utilizing patients by diverse factors in Korea. METHODS: Questionnaires were sent via mail to 140 standard mental health centers from October to December of 2008. 64 facilities responded and data of 461 mentally disabled who are registered at and utilize the services of these mental health centers were analyzed. T-test and cross-analysis were performed to determine the differences in the averages of the variables and the discrepancy in ratios, respectively. RESULTS: Differences between long-term psychiatric inpatients and community mental health services-utilizing patients were seen in characteristics such as gender, age, type of medical coverage, family support systems, diagnosis, age of onset, duration of hospitalization, community-dwelling period, and clinical symptoms and functions. It was significantly short in length of stay in facilities in users of community mental health services with comparison to institutionalized patients. CONCLUSION: The results of this study suggest that invigoration of community mental health services is an alternative that can help deter long-term hospitalization.

PURPOSE: This study was carried out to clarify the histological characteristics of the interface of the corneal stroma and Descemet's membrane of the human eye. METHODS: Nighteen donor eyes without corneal pathology were examined by scanning and transmission electron microscopy. The Descemet's membrane including the corneal endothelium was cheked for scanning electron microscopy. The junctional characteristics of the posterior corneal stroma and Descemet's membrane was examined by transmission electron microscopy. RESULTS: The scanning electron microscopy showed that collagen sheet faced each other at the right angle near the Descemet's membrane and penetrated the Descemet's membrane with the irregular arrangement. The transmission electron microscopy showed that the electron-dense collagen filaments extended to the posterior stroma from Descemet's membrane. The arrangement of electron-dense collagen filaments paralleled with the arrangement of the collagen fibrils of the posterior stroma. CONCLUSIONS: The interface of the corneal stroma and Descemet's membrane was composed of two-typed extracellular materials without the intercellular specificatons.

Among 202 aneurysmal patients with SAH who were admitted to Kyungpook National University Hospital from Jan. 1984 through Jan. 1988, the incidence of ventricular dilatation confirmed by postoperative follow-up brain CT scannings was 32.2%(65 cases). And 33 cases(19.3%) was in mild ventricular dilatation, 9 cases(4.5%) was in moderate and 23 cases(11.4%) in severe who needed the shunting procedure were analysed. The incidence of ventricular dilatation to the site of aneurysm was highest in A-com A. aneurysm(42.2%), followed by P-com A. aneurysm(36.4%) and MCA aneurysm(11.3%). The incidence of ventricular dilatation and the need for shunting was higher in multiple bleeding patients than the single. The good risk patients had meaningfully lower incidence of ventricular dilatation than the poor risk group. In the delayed surgical group showed significantly more numbers of ventricular dilatation needing the shunt than the cases in early group.

Analyses and studies have been made on 34 cases of the combined ICH, showing mass effect among 305 male and female ruptured intracranial aneurysmal patients who were admitted to Kyungpook National University Hospital from Mar. 1984, through Feb. 1990. The incidence of the large ICH was 11.1% with 2.1 to 1 ratio of male to female. The highest age incidence of the hematoma was in the 40 to 60 years bracket. The most frequent site of the aneurysm combined with the large ICH was at MCA aneurysm, 38.6%, followed by at A-com artery aneurysm, 4.8%. The most frequent location of the hematoma was in temporal lobe, 88.2%. The rate of combined large ICH was 20.3% in multiple aneurysmal bleeding patients who revealed higher incidence of the hematoma than the single bleeding patients. In amount of the hematoma, 30-40ml bracket ranked top occupying 32.4% of all cases. After surgical treatment, 29.4% patient was improved to the good and fair on discharge. The rate of mortality was 61.8%, which was mainly due to direct effect of hematoma and cerebral infarction caused by vasospasm.

OBJECTIVES: The aim of this study was to investigate the correlated factors that may influence the length of stay in mental health related facilities. METHODS: We chose 2253 patients with mental illness using a stratified multi-stage cluster sampling from 48 psychiatric hospitals, twelve psychiatric clinics, five psychiatric welfare facilities, and five mental rehabilitation facilities. The investigation involved psychiatrists, psychology practitioners, and social workers, and lasted from August 1, 2008 to November 15, 2008. Assessment and investigation of diverse factors was performed using one-way analysis of variance in order to examine their influence on length of stay. RESULTS: Factors showing significant correlation with length of stay included the types of mental health related facilities, age, marital status, socioeconomic status, type of medical security, familial support, type of admission, diagnosis, age of onset of the illness, number of admissions, severity of psychiatric symptoms, daily living and social function, GAF score, prominent thought/perception disability, memory/orientation disturbance, odd behavior/prominent regression, personal hygiene, communication/personal relationship, management of money, and public transportation/facility utilization. CONCLUSION: Findings of this study suggest that the type of mental health related facilities and the type of medical security are the most significant factors showing correlation with length of stay.

BACKGROUND: Outpatient surgery has recently grown at a substantial rate. The development and use of short acting anesthetic and analgesic agents have played a major role in the growth of outpatient surgery. This study was designed to evaluate the intraoperative hemodynamic responses and recovery characteristics, using propofol or isoflurane to maintain the anesthesia. METHODS: A total number of 30, ASA physical status I-II patients scheduled for outpatient surgery, all of whom were to undergo excision of breast mass. The patients were randomly allocated to receive either total intravenous anesthesia with propofol, or inhalation anesthesia with isoflurane after induction of anesthesia with propofol. All patients were ventilated via a laryngeal mask airway (LMA) using a mixture of oxygen and air so that the FiO2 would be 0.4. RESULTS: There were no significant differences in hemodynamic changes during anesthesia in recovery time, or in complications between the two groups. CONCLUSIONS: We conclude that both methods provide reasonably rapid and reliable recovery from anesthesia and are equally acceptable to the patients.
