Spinal instrumentation is popular nowadays. After applying the Harrington distraction rod, there might be a severe, tragic complication, paraplegia. Recently SSEP is widely used to detect the early change of the spinal cord dysfunction. The force to correct the spinal deformity is usually distraction. The distraction force will stretch the spinal dura. But the relation of neural deficit between distraction force and duration is not clearly determined yet. Also the anatomical level of neural deficit is not known. The purpose of this study is to find that the distraction force of 200gm on the spinal dura will change the SSEP by the stimulation of the posterior tibial nerve and if there is change of SSEP, what portion of nerve stimulation pathway is responsible for. Results are as followings. 1) The distraction force of 200gm makes change of SSEP wave. 2) P2 wave is most susceptible, N1 wave is less susceptible and P1 is relatively contant for one hour dural traction. 3) After release of traction, the wave is partially reversible but not completely for next one hour recovery period. 4) While the wave of SSEP is changed by the dural distraction force, the nerve conduction between the nerve root just outside of the spinal dura and calf shows constant latency. That means the anatomical level responsible for the change of SSEP wave is proximal to the spinal dura, not the peripheral nerve distal to the spinal dura.

237 patients with Legg-Calve-Perthes disease were treated during past 12 years. Among them, a comparative study was done for 87 patients who were followed up over 2 years. They were analyzed according to Catteralls classification and divided into a group of conservative treatment and of surgical treatment. 74 patients were boys and 13 patients were girls and the ratio of boys to girls was 5.7 to 1. The mean age was about 6.9-year-old. Bilateral involvement was observed in 6 patients. According to Catterall classification. 1(1.1%) was classified as group I, 27(29.0%) as group II, and 36(38.7%) as group III, and 29(31.2%) as group IV. According to assessment by Harrison et al., satisfactory result was achieved in 63.2% of cases of conservative treatment and 34.3% of cases of operative treatment. The measurement of epiphyseal quotient and femoral head sphericity(by Mose) were considered meaningful methods for assessing the result of the treatment. The most frequent one of “Head-at-Risk” factors was lateral subluxation of femoral head. The result of treatment was not always coincided with the classification by Catterall. In bilateral involvement, the first affected hip had better prognosis than contralateral one.

The skin defect with sensory impairment of volar aspect of fingers should be reconstructed for the better function of hand. The Neurovascular island graft has been used to provide sensation to volar surface the thumb and to replace pulp tissues avulsed from thumb or index finger. Authors performed neurovascular island graft for defective sensibility of finger tip loss in 14 cases since Jun. 1979 to Mar. 1985. The donor flaps were obtained from the ring finger in 9 cases and middle finger in 5 cases. Among 14 cases, the donor flaps were taken from the ulnar side of 3rd and 4th finger in 11 cases. We followed up the the patients from 7 months to 4 years and 6months and in last follow-up, recovery of protective sensation such as sharp/blunt discrimination, temperature discrimination, and touch/stroke discrimination, was good but two point discrimination and reorientation of sensa-tion were poor. Cold intolerance was developed in 11 cases, and longitudial linear scar band of donor digit was demonstrated in 12 cases.

Antiviral treatment of hepatitis B is one of the most rapidly evolving fields in current medicine. Guidelines for the management of chronic hepatitis B (CH-B) have been proposed and revised by many academic societies and groups. Recommendations for nucleoside or nucleotide analogue (NUC) therapy from representative current guidelines are compared herein with each other and with previous guidelines. Several differences among individual recommendations may reflect regional and temporal differences as well as differences in the available data upon which the guidelines are based. Nevertheless, these guidelines share a common principle regarding NUC treatment for CH-B: long-term viral suppression by the drugs with potent antiviral activity and low rate of development of drug resistance to prevent disease progression. A review of the past and current guidelines for the management of CH-B would be useful for evaluating the current status of management of the disease and to identify better solutions for improving the outcome of patients with CH-B.

Background:Eutropin is a recombinant human growth hormone preparation and has been used in patients with growth hormone deficiency. Short stature is a characteristic feature of Turner syndrome, which is caused by sexual chromosomal anomalies. Growth hormone therapy would increase growth velocity and increase the ultimate final height in patients with Turner syndrome. The purpose of this study was to evaluate the clinical effects and safety in patients with Turner syndrome with Eutropin treatment. Subjects and METHODS:60 patients with Turner syndrome,who were diagnosed by chromosome study,were treated with Eutropin 1IU/kg/week for 12 months and followed up every 3 month. The height and weight were evaluate at 0, 3, 6, 9, 12 months. A complete blood count, ESR, urinary analysis and chemistry studies were done every 3 month. IGF- I , T4, TSH & anti-GH antibody were measured at 6 months and 12 months. Chest X-ray was checked at 0, 6 ,12 months. RESULTS:60 patients were enrolled but 10 patients were lost or treated irregularly and excluded in the study of growth effect. but included all cases in safety analysis. At the onset of Eutropin therapy,their mean age was 10.8+/-2.9 years old(range 4.2- 14.9yr)and the height was 121.1+/-13.7cm(-3.1+/-0.9 SDS) and yearly growth velociy was 3.4+/-1.5cm. Their weight was 30.5+/-10.6kg and bone age 9.1+/-3.0 yrs. After Eutropin treatment, mean height was increased to 123.2+/-13.5cm at 3 months, 125.2+/-13.1cm at 6 months, 127.5+/-12.4cm at 9 months, 128.3+/-12.8cm at 12 months. Height velocity were increased to 8.3+/-3.1cm at 3 months, 8.1+/-2.6cm at 6 months, 7.6+/-1.9cm at 9 months and 7.1+/-1.9cm at 12 months(P<0.001). Height SDS at 0, 3, 6, 9, 12 months were -3.1+/-0.9, -2.9+/-1.0, -2.7+/-0.9, -2.7+/-0.9 respectively(P>0.001).Their bone age were 9.1+/-3.0yr, 9.6+/-2.9yr, 10.2+/-2.7yr before and 6 & 12 months after treatment respectively. HA/BA were 0.84+/-0.15, 0.87+/-0.13, 0.88+/-0.12 at before and 6 & 12 months after treatment respectively(P<0.05). Growth velocity of 4-8 yrs group was most prominent compared to other groups. Serum IGF- I concentration was increased from 167.4+/-85.8ng/ml to 368.4+/-158.1ng/ml at 6 months and 423.2+/-181.0ng/ml at 12 month(P<0.001) after treatment. No significant changes were observed in thyroid function, CBC, ESR, Blood chemistry and urinalysis. Anti-hGH antibody were positive in 2 patients, but these didnot attenualte the growth velocity. CONCLUSION: Treatment with Eutropin increased significantly height velocity in patients with Turner syndrome. No specific adverse events were observed during Eutropin therapy.

Actinomycosis, in which the principal causative agent in man is known to Actinomyces israelii, is a chronic, suppurative diseases characterized by extensive fibrosis, multiple abscesses, and formation of sinus tracts that drain suppurative exudates. On the basis of the anatomical sites involved; it can be subclassified into the cervicofacial form, which is the most common form, pulmonary form and abdominal form. Kidneys are rarely affected. Clinically, radiologically, and at operation it is difficult to differentiate the renal actinomycosis from renal tuberculosis and renal carcinoma. The prognosis is excellent after nephrectomy followed by appropriate antibiotic therapy. We presented a case of renal actinomycosis with a brief review of the literatures.

A pathological fracture occurs spontaneously or with minimal trauma. The underlying pathological changes may be subtle and the diagnosis not obvious. The two goals in the treatment of pathologic fracture in weight bearing long bones are to provide relief of pain by secure fixation of the fracture and to permit early smbulation and a prompt return to prefracture status. Thirteen cases of pathological fracture were treated during the period from June, 1986 to February, 1988 at Kangnam Sacred Heart Hospital. The results are as follows. 1. Most patients were over 45 of age. 2. Malignancy was the common cause. 3. Most frequent involved site was femur. 4. Occured by trivial trauma such as slip down injury. 5. Satisfactory result by curettage, open reduction and internal fixation, bone graft or bone cement augmentation.

In the general, Disodium estdronate (EHDP) had effects of inhibition in bone resorption, dissolution of hydroxyapatite crystal and decreasing the turn over rate in Paget's disease. Clinically it is used as the drug of treatment for the osteoporosis, heterotropic ossificatiom and Paget's disease inspite of some, controvesies, but there is few article about the effect of EHDP on osteoblast. Authors tries to observe the effect of EHDP on osteoblast using the MC3T3-El osteoblast cell line which has very similar chrateristics with human osteoblast and evaluate the effect by the criteria of changes of morphology, number of osteoblast, and alkaline phosphatase activity. The results are obtained as following: l. EHDP has direct inhibitory effect on the proliferation of osteoblast. 2. EHDP increase the alkaline phosphatase activity in vitro.

Sixty-eight discoid meniscus in sixty-seven patients confirmed by arthroscope have been analysed and operated upon at Kyung Hee University Hospital between 1976 and 1984. It is the purpose of this paper to study the clinical characteristics of the discoid meniscus and classify the type of tom discoid meniscus for the accurate diagnosis and the effective treatment. The types of torn discoid meniscus could be classified into 6 types, which had specific clinical, arthrographic and arthroscopic findings, respectively. The type Vwas most common. Of 52. 2% of cases of the discoid meniscus, the patients were in the second decade of life at the time of operation, varying in age from 7 years to 53 years. In the 55. 2% of cases of the torn discoid meniscus, there were no history of specific trauma. The clinical diagnostic accuracy was 61.8% and the diagnostic accuracy of arthrography was 86%. Partial and total meniscectomy through arthroscope showed better results in follow-up study.
