Chronic anteromedial rotatory instability has not been demonstrated to have a satisfactory solution and we have experienced recurrence of the instability after operations. So the authors devised a new operative technique for the TCL (Tibial collateral ligament), that is, burying of the torn end of the ligament beneath the “ㄷ” shaped bony flap. It would better be called advancement and bony reinsertion operation. And we performed modifed MacIntosh tenodesis for the torn anterior cruciate ligament. The results were as follows: l. Of six knees, four (66.6%) rated “good”, two (33.3%) “fair”, and none (O%) “poor” (follow-up period; at least 6 months). 2. The technical problem of the advancement and bony reinsertion operation was discussed.

PURPOSE:There is a clear sexual dimorphism in circulating concentration of leptin in adulthood. However, we don' know when such dimorphism begins and how much pubertal development influences on it. So we examined body composition and circulating concentrations of leptin according to Tanner stage(TS). METHODS:We examined 112 children(M; 56, F; 56, Age; 8.5-17 yr) to evaluate the relationship of leptin and body composition. Body composition was determined by bioelectric impedence measurements(BIA) and by anthropometry. Leptin was measured by human specific RIA. Leptin level was analysed according to TS, body mass index(BMI), fat mass(FM), and lean body mass. RESULTS:BMI and free FM was correlated with TS in both sexes. FM was closely correlated with TS in girls but not in boys(M; r=0.08, P=0.54. F; r=0.73, P>0.001). Leptin levels increased in girls with advanced TS(r=0.355, P<0.01), but decreased in boys(r=-0.339, P<0.01). A strong exponential relationship was observed for leptin levels with BMI, FM, and percentage body fat as determined by BIA. There was significant sexual dimorphism of leptin level at TS VI/V. Because leptin level was significantly related FM, leptin level was normalized to FM(Leptin/FM). Leptin/FM of females(0.67+/-.27 ng/mL/kg) was also significantly higher then that of males(0.31+/-.15 ng/mL/kg)(P<0.001). CONCLUSION: These data suggest that plasma leptin levels increase in girls and decrease in boys after TS II as pubertal development proceeds; they show a significant gender difference, especially late puberty, even after adjustment for FM. Sexual dimorphism in leptin during puberty reflects not only differential changes in body composition but also different leptin resistance; reference ranges of leptin could be modified by TS and gender.

The eye is a common target organ of the allergy, and allergic conjunctivitis is the most common of eye diseases. Clinical manifestations of allergic conjunctivitis are acute bilateral red, itchy, and watery eyes. The presence of conjuncitival eosinophilia may be consided to be a diagnostic indicator of allergic conjunctivitis. ECP is a quantifiable toxic product secreted by activated cosinc phils. VCAM-1 promotes adhesion of leukocytes to endothelium in vitro and may promote imflammation in vivo. The objective of this study is to measure eosinophil count, ECP and sVCAM-1 levels of tears and sera in patients with acute allergic conjunctivitis and normal subjects and to assess the correlation of these mediators with the severity of the disease and the clinical usefulness. Seventeen subjects were selected on the basis of clinical manifestations, history, skin prick test, total IgE. A microcapillary tube was used to collect the tears from the inner canthus, conjunctival epithelia were obtained for eosinophil count by scraping the upper tarsal conjunctiva. The level of ECP was measured by CAP system (Kabi-Pharmacia, Sweden), sVCAM-1 was measured by ELISA (R&D, USA). Serum IgE and eosinophil count were in creased in 10 patients, allergic skin prick test were positive in 11 subjects (D.p: 9, D.f: 8), eosinophilia in conjunctival epithelium were present in 11 subjects (4 patients: > 3/HPF, 7 patients: 1-3/HPF). ECP in tears were increased in patients significantly (12.0+8.0 vs 3.9+3.8 ng/ml, p=0.01), but not in serum (52.5+43.1 vs 28.3+25.9 ng/ml). There is no significant correlation between eosinophil count and ECP in serum and tears (p>0.05, r-=0.19). Serum sVCA-M-1 level is significant different between patients and controls (1916.5+756.0 vs 1147.2+146.1 micro gram/ml, p=0.01), sVCAM-1 is significantly correlated to eosinophil count (p=0.01, r=0.56) and ECP (p<0.05, r=0.65). In conclusion, eosinophil and ECP in tears may be very important role in allergic conjunctivitis and are useful indicators of the disease. The elevation of sVCAM-1 in serum may be interpreted simply as marker of the presence of non-specific inflammation.

Mitral valvular orifice area is important for the evaluation of prognosis and treatment of patients with mitral valvular stenosis. Until recently, Gorlin's formula using cardiac catheterization has been utilized in the measurement of mitral valve area, but it is invasive and impractical to examine repeatedly. Recently 2-Dimensional echocardiography appeared to be a practical and useful substitute in measurement of valve area and also it is economical and has no risk to patients. In 31 patients with mitral valvular stenosis examined at the echocardiography room of Busan national University Hospital from March 1982 to March 1983, we measured the mitral valve area with 2-Dimensional echocardiography and evaluated its relationship with the left ventricular functions measured on M-mode echocardiogram. Among many parameters on M-mode measurements EF slope, excursion amplitude and the ratio of left atrial dimension to aortic root dimension were rather helpful for the assessment of severity of mitral valvular stenosis than other parameters. And each relationship with the valve area showed correlation coefficient of 0.60, 0.05 and -0.58, respectively.

Objectives: Cognitive behavioral therapy for insomnia (CBT-I) is the first line treatment for insomnia. However, many patients remain with sleep disturbances even after undergoing CBT-I, and those with short sleep durations have shown fewer gains. Acceptance and commitment therapy (ACT) is one of the third wave of behavioral therapies, and it is useful in helping patients get flexibility of mind. Therefore, we incorporated its components into CBT-I, came up with an advanced CBT-I program that involves cognitive behavior therapy based on ACT, and examined its efficacy in comparison to that of CBT-I. Methods: Patients with chronic primary insomnia were recruited at the memory center of CHA University Hospital from June to August 2020. To examine the efficacy of advanced CBT-I compared to that of CBT-I, the patients (n=16) were assigned to two groups (CBT-I: n=6; advanced CBT-I: n=10). The patients in each group were treated for 4 weeks (8 sessions). The quality of sleep, severity of insomnia, sleepiness, depression, anxiety, acceptance, efforts to sleep, and dysfunctional beliefs concerning sleep were assessed with self-report questionnaires. Results: The severity of insomnia, quality of sleep, depression, anxiety, acceptance, efforts to sleep, and dysfunctional beliefs concerning sleep improved after both CBT-I and advanced CBT-I treatment. Conclusions This study examined the efficacy of advanced CBT-I in improving the severity of insomnia, sleep quality, and other symptoms related to sleep. The results suggest that components of ACT were useful for insomnia.

Composite grafting remains a technique which is used reluctantly and without great hope of success. In the recent two years, unexpectedly good result of composite graft was gained from 30 cases. The purpose of our study is to identify factors influencing success and to overlook long-term problems from a cosmetic and a functional view point. A retrospective review and a questionnaire about 30 fingers of 29 patients which were operated for composite graft at Kyongju hospital of Dongguk university from March 1997 to February 1999 were carried out. In all cases of composite grafting, tie-over dressing and heat lamp were applied and left for five days. And following result and conclusion were obtained. 1. 24(80%) of 30 finger tips replaced as composite graft were survived completely or partially. 2. At children with an age range 1 to 14, the survival rate (100%) of composite grafted tips was higher than that (75%) at adults. So, patient's age was important factor for success. 3. The type of injury was more important factor than the level of amputation. The survival rate(100%) of tips to cutting injury was higher than that(75%) of tips to crushing injury. 4. The delay in time from amputation and replacement did not significantly correlate with the survival rate. But, all tips replaced within 3 hours were survived completely or partially. 5. Even if partial necrosis on grafted tips was present, a result of long-time conservative treatment with minimal debridrement was excellent. Especially in children, the tips with conservative treatment showed normal appearance, several months later. 6. Cosmetic and functional results were better in child group and in groups with higher survival rate. Most common problem in cosmetic aspect was a short digit and that in functional aspect was a tender tip. 7. As a heat lamp increased blood supply, we could obtain better outcome.
