This is to present 44 cases of hip fractures, of these 28 being fractures of femoral neck and the remainder, intertrochanteric, which were treated at the Department of Orthopedic Surgery, Seoul National University Hospital for four years and 8 months from Jan. 1965 to Aug. 1969. 1. There were 33 males. and 11 females in the series. 26 cases(59.1) were over 51 years of age. 2. The femoral neck fractures were treated by means of Smith Petersen nailing in 16 cases, modified Girdlestone hip arthroplasty in 3 cases, Austin-Moore hip prosthesis in 6 cases and other methods in 3 cases. 3. Modified Girdlestone hip arthroplasty could be a treatment of choice for femoral neck fracture requiring hip arthroplasty for those unsuitable for extensive surgery. 4. The intertrochanteric fractures of femur except for 3 unstable fractures were treated successfully with the Smith-Petersen nail and plate, following anatomical reduction of fracture. In 3 unstable fractures, satisfactory stabilization and internal fixation was obtained by the method of medial displacement of proximal part of distal fragment of fracture.

Five cases of the spinal tuberculosis with severe kyphosis and paraplegia were treated with radical surgery at the Department of Orthopedic Surgery, Seoul National University Hospital. All the cases were involved at the thoracic spine and kyphosis were ranged 100 through 150 degrees. Severe fixed chest deformity and impaired pulmonary function were observed. By thoracotomy, aorta was seen to be adherent to the surrounding tissue and this was separated from the verterbral lesion with meticulous procedure. The focus was curetted radically exposing spinal cord which was decompressed with anterior transposition. Then the spine was stabilized with anterior interbody fusion. Postoperative intensive pulmonary care and antituberculous therapy are imperative for the good result. Spinal tuberculosi with severe kyphosis and paraplegia could be benefited with the radical surgery by the experienced surgeon.

Aurthors have treated 77 cases of acute supp rative osteomyelitis since January 1972 until December 1979. Among them 69 patients had surgical treatment while 8 cases had antibiotic therapy only. 42 patients out of 69 surgically treated cases had fenestration operation, while 27 cases had multiple drilling operation to evacuate the bony abscess. In 15 cases Turkels bone biopsy needle was used to decompress the infected bones, and by It the abscess could be very effectively evacuated. After decompression with a Turkel needle by placing a small calibered polyethylene tube Into the lesion, the lesion was continuously irrigated with antibiotics solution. This procedure has proved to be very effective and a successful one which can easily be practised as an office procedure in the very poor and needy cases. Also when patients are seriously ill and/or other extensive surgery is not feasible, this simple procedure can easily be practised without hazard, Good end results without sequellae were abtained when early decompression with massive antiblotic therapy was instituted even by Turkel needle drainage.

The phosphorylation and dephosphorylation of proteins on tyrosyl residues are key regulatory mechanisms of cell growth and signal transduction and are controlled by opposing activities of protein tyrosine kinases and phosphotyrosyl phosphatases (PTPs). We have previously cloned and characterized a nontransmembrane chicken protein tyrosine phosphatase 1 (CPTP1) similar to human placental PTP1B (HPTP1B). CPTP1 contains several phosphorylation sequence motifs (S/T-X-X-D/E) for casein kinase II (CKII), [(I > E > V)-Y-(E > G)-(E > D > P > N)-(I/V > L)] for p56(1ck), and (P-E-S-P) for MAP kinase. To examine whether phosphatase activity of CPTP1 could be controlled by phosphorylation, CPTP1 and HPTP1B fusion proteins purified from E. coil were subjected to the in vitro phosphorylation by CKII. Phosphoamino acid analysis revealed that CPTP1 was phosphorylated on both serine and threonine residues by CKII in vitro. In addition, the degree of the phosphorylation of CPTP1 by CKII was shown to be five times higher than that of HPTP1B. Phosphorylation on both serine and threonine residues of CPTP1 in vitro results in an inhibition of its phosphatase activity. This result suggests that phosphorylation of CPTP1 and HPTP1B by CKII might be implicated in the regulation of their catalytic activities in the cell.

OBJECTIVE: To analyze the interrelationship between homocysteine and methylenetetrahydrofolate reductase (MTHFR) mutation in patients with recurrent spontaneous abortion. MATERIAL AND METHOD: Homocysteine and MTHFR mutation were tested by fluorescent polarizing immunoassay and PCR-RFLP method, respectively. RESULTS: In patients with homocysteine level less than 5 mmol/L, there was no case of normal group but there were four cases of heterozygosity and one case of homozygosity. In patients with homocysteine level 5~10 mmol/L, the number of normal, heterozygosity and homozygosity group were eleven, eighteen and eight, respectively. In patients with homocysteine level 10~15 mmol/L, the number of normal, heterozygosity and homozygosity group were four, one and one, respectively. In patients with homocysteine level more than 15 mmol/L, there was no case of normal and heterozygosity group but there were two cases of homozygosity. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. And there was a significant relationship between homocysteine and MTHFR mutation.

To check expert opinion about the investigation system of medicine-related death, model for "Death Investigation Center" was suggested and related questionnaire were requested. Between 15 December 2009 and 5 April 2010, we sent e-mails of the questionnaire which asked the opinion for the new postmortem investigation system. We sent the questionnaire to 3,289 lawyers and 4,523 doctors (total 7812), and received 100 replies out of the total. All the lawyers and doctors interviewed knew the importance of the postmortem investigation system. Most of them (87%) agreed to the introduction of the new postmortem investigation system. Some of them thought that protector's agreement was necessary for the postmortem investigation (21%), and more doctors were likely to participate with legal protocol (23%). If the postmortem investigation could not be performed due to the protector's disagreement, another specialized medical investigation should be needed to figure out the cause of death (85%). The new postmortem investigation system should be performed by the specific institution, and supported by the government (44%). In many expert's opinion, nonmedical experts such as lawyers and priests should be included for the institution of investigation for objectivity and neutrality (72%). This sample study finds that the postmortem investigation performed by specialized institution is necessary to determine the cause of death in the hospital. For the operation of the system, neutrality and the operating core would be the most important.

Clinical study was made on 675 cases of newborn infant who were born by vacuum extraction during the period of January 1971 through December 1975. The results obtained were as follows: 1. The incidence of vacuum extraction among 4,153 deliveries was 16.3% and there was a slight decreasing tendency annually. 2. The highest maternal age incidence was 26 to 30 years of age and vacuum extraction rate was higher in primipara (75.6%) than multipara (24.4%). 3. There were more male (62.2%) than female (37.8%) and 91.6% of the infants were born with 40 to 41 weeks of gestational age and 89.3% of in infants weighing between 2,500 to 4,000g at birth. 4. The majority (774.6%) of the newborn infant had good (10) Apgar score at one minute and only 5.6%had score below 7. 5. The major complication was head injuries and which were 91.1% of increased size of caput succedaneum, 3.1% of scalp abrasion, 3.4% of cephalhematoma, 0.3% of intracranial hemorrhage, and 0.3% of linear skull fracture, Visible jaundice was found in 9.0% of the newborn infants among those 80.3% showed total serum bilirubin level of 15mg/100ml or less, 19.7% showed 20mg/100ml or more but there was no case of severe jaundice required exchange transfusion.

Emphasis on healthcare during the 1990s has been to provide both optimal wellness and function with quality in a cost-effective manner. Critical Pathway was developed to meet the need to guide clients along the continuum of care and to achieve continuity of care. The purpose of this study was to develop on evaluating model of Critical Pathway practices. The topics which developed into Critical Pathway were normal delivery, repairment of cataract, cesarean section delivery, pediatric tonsillectomy and hemorrhoidectomy. The main goals set by teams were educations, improvement of process and quality of care, customer satisfaction and financial achievements. To evaluate the performace of Critical Pathway in clinical process, 13 kinds of perspective key performance indicators were selected by using Balanced Scorecard(BSC) method. The analysis method was Data Mining. Cesarean section discharge abstract data were reviewed for guidelines of model development and classification of control groups. Five kinds of Critical Pathway were developed by multidisciplinary participation by personnels of related departments, and pilot-test was performed. All the Critical Pathway was applied as standard protocols in patient s care since November, 1999. Length of stay was significantly shortened and increased patient s satisfaction in 4 case groups except pediatric tonsillectomy group. Hospital and medication cost of each patient remarkably decreased in all 5 case groups. And the improvement of process and quality of care was appeared during the Critical Pathway implementation period. These results show that new evaluation model of Critical Pathway in medical practice was an effective.

PURPOSE: The aim of this study was to introduce a method of obtaining the oscillation graphs of the dental x-ray tube heads relative to time using an accelerometer. MATERIALS AND METHODS: An Accelerometer, Piezotron type 8704B25 (Kistler Instrument Co., Amherst, NY, USA) was utilized to measure the horizontal oscillation of the x-ray tube head immediately after positioning the tube head for an intraoral radiograph. The signal from the sensor was transferred to a dynamic signal analyzer, which displayed the magnitude of the acceleration on the Y-axis and time lapse on the X-axis. The horizontal oscillation of the tube head was measured relative to time, and the settling time was also determined on the basis of the acceleration graphs for 6 wall type, 5 floor-fixed type, and 4 mobile type dental x-ray machines. RESULTS: The oscillation graphs showed that tube head movement decreased rapidly over time. The settling time varied with x-ray machine types. Wall-type x-ray machines had a settling time of up to 6 seconds, 5 seconds for fixed floor-types, and 11 seconds for the mobile-types. CONCLUSION: Using an accelerometer, we obtained the oscillation graphs of the dental x-ray tube head relative to time. The oscillation graph with time can guide the operator to decide upon the optimum exposure moment after xray tube head positioning for better radiographic resolution.
