STUDY DESIGN: Ninty eight patients with multilevel spinal stenosis who were treated with posterior decompression and instrumented posterolateral fusion were reviewed retrospectively. All patients were divided two groups by pathologic level and surgery level. One is complete level decompression group (whole pathologic levels were decompressed) and the other is limited level decompression group (less than pathologic levels were decompressed). SUMMARY OF BACKGROUND DATA: Many patients with spinal stenosis haute multilevel pathology, which is very difficult problem to make surgical strategy for determination of decompression level. METHOD: Patients were reviewed using combination of clinical records, follow-up examinations and radiographs. Posterior decompression and instrumented posterolateral fusion were performed in all patients using pedicle screw fixation (TSRH 49 cases, Diapason 37 cases, CCD 12 cases) and either autogenous bone graft alone or autograft with allograft. The average follow-up period was 19.7 months. RESULTS: In the clinical results by the criteria of Kirkalldy-Willis, there was no difference between complete level decompression group and limited level decompression group. By the bone graft mothorts, fusion rate was no difference between autograft alone group and autograft with allograft group, but fusion periods were more shorter in autograft alone group than in autograft with allograft group(P>0.05). CONCLUSION: In multilevel spinal stenosis, the segments that associated with neurologic symptoms or seyeie stenosis on radiograph must be decompressed but the segments that not associated with neurologic symptoms and mild stenosis on radiograph do not need preventive decompression.

The injured tendon is thought to be healed by, extrinsic healing from tendon sheath and adjacent connective tissue, and intrinsic healing from epitenon and endotenon. About the factors influencing the healing of injured tendon, many authors reported the effects of mobilization, electricity, ultrasound and various druge. Especially, active or passive mobilization had been known to promote the healing process and to reduce adhesion. To investigate the influences of active limited mobilization, intrinsic and extrinsic healing process, right Achilles tendons of 30 New Zealand white rabbits were grouped according to the types of treatments (Group I; tenotomy of Achilles tendon only, Group II; Tenotomy and long leg cast, Group III; surgical repair after tenotomy and long leg cast). The tendon sheath was repaired in all the groups, and the left Achilles tendons were used as control. At six weeks after operation, the tendons were removed and analysed biomechanically using Instron 1000, and histologically. The following results were obtained: 1. There were significant decreased of break strength, in order of Group III, Group I and Group II(p < 0.05). But, no difference was found between control group and Group III. 2. Extension length to the rupture, was decreased significantly in the experimental groups than control group. But there was no difference among the experimental groups. 3. Histologically, dense proliferation of fibroblasts and hypertrophy of tendon was observed in Group I; and matured fibricytic tendon tissues in Group II and III. In Group II, the amount of matured tendon tissues and degree of maturity were less than in Group III. In summary, suture and active limited motion were considered as promoting factors on the tendon healing.

3.An Analytic Study of Medical Records in Sam-Kuk-Sa-Ki.
Korean Journal of Medical History 1992;1(1):83-87
In Sam-Kuk-Sa-Ki there are several types of records which are associated with medicine. They are of the plagues, delivery of twins, drugs in use of the time, religious healing and names of some diseases. Records of plagues are most frequently described and they are described associated with climate and natural disasters. Those who delivered twins were awarded by the nation. Because at that time when population was not so large, the population was the power of the nation. As Buddhism was the ruling religion of the time, records of religious healing were mostly associated with the Buddhism. Medical records in Sam-Kuk-Sa-Ki gives us valuable clues to the understanding of the medicine of the time, the ancient Koreans' concept of diseases and the way how they confronted them.

4.On Hansung Physicians Association.
Korean Journal of Medical History 1992;1(1):31-35
Hansung Physicians Association was organized in Dec. 1915. Its members were medical practitioners residing in Kyungsung(Seoul). It was apposed to Kyunsung physicians Association, of which members were Japanese. After the foundation of Hansung Physicians Association some other local physicians associations were beginning to be founded. Hansung Physicians Association's social activities were fee-free round practice and improving sanitary conditions. It was basically gathering-meeting or interest group for doctors, which is reflected in the fact that Hansung Physicians Association limited its members as medical practitioners. It is contrasted with the Chosun Medical Association which was founded in 1930. Chosun Medical Association differs from Hansung Physicians Association in the it was a academic association. The first issue of Bulletin of Hansung Physicians Association was published in August 1933. But it came to be the last issue. Hansung Physicians Association was disorganized compulsarilly in 1941 by Japanese Government-General of Korea

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.

BACKGROUND: One of the problem in emergency room(ER) of university hospital is over-crowdedness that causes exhaustion of medical resources (personnel, device, space) and disturbes optimal treatment. METHODS: This is an evaluative research for the purpose of promoting efficient operation system in ER of university hospital. RESULTS: 1) In 387 visitors, mean age was 47.5 years, and male to female ratio 1.21:1. As the specialty in charge, 28.9%f them were internal medicine, 26.6%mergency medicine, 9.9%eurology, and 8.5%eurosurgery. 24%f visitors have come by ambulances. The patients stayed for average 16.1 hours. The admission rate of ER visitors was 33.4 %60.3 %returned home after some management. 2) The visitors had various causes without correlation between the severity of conditions and the choice of high level hospital ER. They perceived their situations emergent in 78.4% but after triage only 25.6%were classified emergent. 48.6%of the visitors were the patients of out-patient department of this hospital due to chronic diseases. 3) The patients were assessed within 9.5 minutes after arrival at ER by nurse and within 34 minutes by doctor. If they were in need of consultation to second/third department, they waited for 141.5/460 minutes respectively to see the doctor. They waited for 59.9/52.7 minutes to get routine laboratory sampling/radiologic examination respectively. 4) Every 2.3 new patients visited this ER per hour. Average 63.2 patients were taken over to next shirt of nurse duty, and 60%of them had chronic degenerative diseases. CONCLUSION: The causes of overcrowding in ER of the university hospital were (1) huge number of patients at out-patient department of the hospital, (2) shortage of beds compared to the number of patients waiting admission, (3) too many kinds of procedures performed in ER, (4) cooperation failure among doctors of different specialty, and (5) no definite criteria of admission/discharge into/from ER. To solve these problems, conversion of ER management policy from complete examination and treatment to more simple and rapid one is necessary.

BACKGROUND: Proximal humerus fracture is considered to be the third most common fracture for patients aged 65 years or older. Conservative treatment has been known to treat most of humerus fracture. However, fractures with severe displacement or dislocation may require surgical treatment. Intramedullary fibular allograft with a locking plate is frequently used in patients accompanying medial metaphyseal disruption. In this study, author intends to evaluate clinical and imaging results based on patients who underwent surgical treatment using fibular allograft with a locking plate. METHODS: This study is conducted prospectively at Wonju Severance Christian Hospital, targeting patients who previously underwent surgical treatment using open reduction and intramedullary fibular allograft with a locking plate between 2011 and 2015. A total of 26 patients were evaluated on the following: postoperational clinical assessment measuring Constant score, American Shoulder and Elbow Society (ASES) score, and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Postoperational imaging assessments are evaluated via measuring the neck-shaft angle. The study subject were Neer classification type 3, 4 proximal humerus fracture cases with disrupted medial hinge and having cortical comminution in the region of the surgical neck. RESULTS: The average period of progression was 22.5 months, and the average age of patients was 72.6 years. At the final follow-up, the average Constant, average ASES, and average DASH scores were 80.1, 78.5, and 20.6 respectively. The average neck-shaft angle was 127.5°. CONCLUSIONS: In conclusion, fibular allograft augmentation with a locking plate showed satisfying results in both clinical and imaging studies.

PURPOSE: To introduce a new convenient and accurate method to measure the angle kappa using ultrasound biomicroscopy (UBM) and corneal topography. METHODS: Data from 42 eyes (13 males and 29 females) were analyzed in this study. The angle kappa was measured using Orbscan II and calculated with UBM and corneal topography. The angle kappa of the dominant eye was compared with measurements by Orbscan II. RESULTS: The mean patient age was 36.4 ± 13.8 years. The average angle kappa measured by Orbscan II was 3.98°± 1.12°, while the average angle kappa calculated with UBM and corneal topography was 3.19°± 1.15°. The difference in angle kappa measured by the two methods was statistically significant (p < 0.001). The two methods showed good reliability (intraclass correlation coefficient, 0.671; p < 0.001). Bland-Altman plots were used to demonstrate the agreement between the two methods. CONCLUSIONS: We designed a new method using UBM and corneal topography to calculate the angle kappa. This method is convenient to use and allows for measurement of the angle kappa without an expensive device.

Endoluminal reconstruction of an intracranial aneurysm using flow-diverting devices, such as the pipeline embolization device (PED), is a new treatment modality with good clinical outcomes. The device was originally indicated for challenging cases, such as wide-necked large or giant aneurysms, and is gaining popularity as a reliable treatment for nearly all intracranial aneurysms. The overall complication rate of flow-diverting devices use is 17.0%, including occlusion of side-branching or perforating arteries, rerupture of the aneurysm, in-stent thrombosis, and, rarely, stent migration. We report a rare complication of the PED: delayed migration of the PED after successful stent implantation during treatment of an unruptured vertebral artery dissecting aneurysm, which resulted in rupture of the aneurysm. Further, we discuss technical steps that can be taken to prevent this potential complication.
