Arthrodesis of the knes has lost its nopularity since the development of modern knee replscement arthroplasties, however it still has its place as a salvage procedure when replacement arthroplasties are contraindicated. Various techniques have been in the use including the time-tested Charnleys compressiori arthrodesis. Instead of using Charnley's and other similar compression devices, the authors applied single or double compression plates in 8 knees with severe destruction and deformities, and the results are summerized ss follows: l. Included in this series are 5 cases of tuberculous arthritis, 1 case of septic arthritis, 1 case of resistant scar contracture, and 1 case of Charcots knee. 2. Successful fusion was obtained within 18th week, aversge 13th week. No case of pseudarthrosis was experienced. 3. 3 cases of postop. wound drainage and 1 case of peroneal nerve palsy were experienced, but these did not compromise the final results. 4. It may be concluded that Arthrodesis of the knee using compression plate is rigid enough to permit early mobilization of patients and get the certainty of union.

Twenty one cases of adult tibial shaft fractures were fixed with flexible intramedullary nails at the Department of Orthopedic Surgery, Kang Nam General Hospital. The results are summerized as follows; l. Average healing time was 17 weeks. No case of nonunion was experienced. 2. As the operation was perfomed by closed method under fluoroscopic control, reduction of operation time is a major advantage. 3. Fixation was usually strong enough to allow immediate weightbearing and mobilization of the adjacent joints without external immobilization. 4. Three cases of delayed union and 2 cases of rotational malunion were experienced, but shortening and angulation were not so severe as to affect overall functional results. 5. In conclusion, Ender nailing is considered to be a valuable method in treating tibial shaft fractures. Even in cases with multiple injuries and in selected open cases, Ender nailing can be a saft procedure.

PURPOSE: Recently, Forkhead box M1 (FoxM1) was reported to be correlated with lung maturation and expression of surfactant proteins (SPs) in mice models. However, no study has been conducted in rabbit lungs despite their high homology with human lungs. Thus, we attempted to investigate serial changes in the expressions of FoxM1 and SP-A/B throughout lung maturation in rabbit fetuses. MATERIALS AND METHODS: Pregnant New Zealand White rabbits were grouped according to gestational age from 5 days before to 2 days after the day of expected full term delivery (F5, F4, F3, F2, F1, F0, P1, and P2). A total of 64 fetuses were enrolled after Cesarean sections. The expressions of mRNA and proteins of FoxM1 and SP-A/B in fetal lung tissue were tested by quantitative reverse-transcriptase real-time PCR and Western blot. Furthermore, their correlations were analyzed. RESULTS: The mRNA expression of SP-A/B showed an increasing tendency positively correlated with gestational age, while the expression of FoxM1 mRNA and protein decreased from F5 to F0. A significant negative correlation was found between the expression levels of FoxM1 and SP-A/B (SP-A: R=-0.517, p=0.001; SP-B: R=-0.615, p<0.001). CONCLUSION: Preterm rabbits demonstrated high expression of FoxM1 mRNA and protein in the lungs compared to full term rabbits. Also, the expression of SP-A/B was inversely related with serial changes in FoxM1 expression. This is the first report to suggest an association between FoxM1 and expression of SP-A/B and lung maturation in preterm rabbits.

The present study was designed to examine the possible relationship between the function of the labyrinth and the role of the sympathetic nervous system In experimental motion sickness produced by rotatory movement(8O r.p.m.). The catecholamines in the brain, the heart and the adrenal gland of rats were rapidly reduced to one half of normal values following exposure to rotatory movement. The pretreatment with streptomycin and dramamine completely prevented the depletion by the rotatory movement of the catecholamines in the brain, the heart and the adrenal gland, but scopolamine did not prevent the decrease. Bretylium or chlorpromazine signifcantly inhibited reduction of the catechol-amines in both of the brain and the heart. However they did not influence the decrease in the adrenal gland. The reduction of the tissue catecholamines in rotatory movement is presumed to be caused largely by activation of the sympathetic nervous system mediated through labyrinthine stimulation.

PURPOSE: The statistical birth data related to maternity and newborns over the past 15 years in Korea was analyzed in order to review the changing patterns of maternity and newborns in Korea. METHODS: Statistical data after 1995 in Korea were obtained from the Statistics Korea. Birth data related to maternity (distribution of birth rate, maternal age, advanced maternal age group, rank of birth, and time of pregnancy) and newborn (distribution of number of births, birth weight, ratio of sex, and multiple births) were analyzed. RESULTS: The average age of maternity is increasing while births in an advanced age has also increased from 4.7% in 1995 to 15.5% in 2009. There was a decrease in the total number of births, total birth rate and average birth weight. The rate of premature births in an advanced age occupied more than 6% of this study. The ratio of sex from the third born child and beyond has been relieved. The rate of multiple births has increased. The birth rate within two years of cohabitation before giving birth to a couple's first child has decreased. CONCLUSIONS: The rates of newborns requiring perinatal care such as births of prematurity, low birth weight infants, multiple pregnancies, etc are increasing. This is in relation to the increase in age of maternity and number of pregnancies in an advanced age. Therefore, there is an increase demand for strategies in order to decrease the age of maternity and the rate of pregnancies in an advanced age.

PURPOSE: To evaluate the results of arthroscopic contouring surgery and posterolateral meniscal repair for pediatrics with snapping discoid lateral meniscus without tear. MATERIALS AND METHODS: Nine children below 10 years, with snapping discoid lateral meniscus without tear were evaluated in this study. 3 cases had a morphologic deformity of lateral meniscus in MRI and arthroscopic findings, but there was no meniscal tear. Only contouring surgery was performed in 6 cases, and in 3 cases, because of the instability of meniscus over 5mm in traction due to the relaxation of the menisco-capsular junction after contouring surgery, posterolateral repair was performed. The average duration of follow up was 39 months(range, 25 to 72 months). RESULTS: Additional posterolateral repair was done due to remaining snapping, in three cases of six contouring surgery cases. In all cases, snapping was disappeared. The average Lysholm score was improved from 71 in preoperative status to 97 in postoperative status(p=0.008) CONCLUSION: In case of the increased instability of the posterolateral corner of lateral meniscus after contouring surgery in the treatment of snapping discoid lateral meniscus, posterolateral repair is effective to improve the snapping symptom from meniscal subluxation.

Antimicrobial agents played a miraculous role in the treatment of bacterial infections until resistant bacteria became widespread. Besides antimicrobial-resistant bacteria, many factors can influence the cure of infection. Nocardia infection may be a good example which is difficult to cure with antimicrobial agents alone. A 66-year-old man developed soft tissue infection of the right buttock and thigh. He was given prednisolone and azathioprine for pachymeningitis 3 months prior to admission. Despite surgical and antimicrobial treatment (sulfamethoxazole-trimethoprim), the infection spread to the femur and osteomyelitis developed. The case showed that treatment of bacterial infection is not always as successful as was once thought because recent isolates of bacteria are more often resistant to various antimicrobial agents, intracellular parasites are difficult to eliminate even with the active drug in vitro, and infections in some sites such as bone are refractory to treatment especially when the patient is in a compromised state. In conclusion, for the treatment of infections, clinicians need to rely on laboratory tests more than before and have to consider the influence of various host factors.

PURPOSE: This study aimed to identify the morbidity in very low birth weight infants (VLBWI) and low birth weight infants (LBWI) in Korea and compare these data with similar data from Japan and the USA. METHODS: The analysis of morbidity in VLBWI in Korea was based on a 2012 survey of morbidity in LBWI in Korea. These findings were compared with the morbidity of VLBWI and LBWI in Japan and the USA. RESULTS: Morbidities in LBWI included jaundice (58.5%), respiratory distress syndrome (RDS; 37.0%), apnea (22.2%), patent ductus arteriosus (PDA; 22.0%), and small for gestational age (SGA; 19.2%). The research findings concerning LBWI morbidity found, high prevalence rates for neonatal jaundice, RDS, PDA, SGA, apnea, and sepsis. Compared with VLBWI morbidity of Japan and the USA, intraventricular hemorrhage, RDS, PDA, and sepsis were more prevalent in Korea, whereas bronchopulmonary dysplasia, necrotizing enterocolitis, and retinopathy of prematurity occurred at similar frequencies in all 3 countries. CONCLUSION: This study provides a recent nationwide summary of disease-specific morbidity in VLBWI and LBWI in Korea. Based on this study, future research and surveys are needed to identify the disease-specific mortality and survival rates in the field of neonatal intensive care.
