A retrospective study was conducted to investigate the effects of CNS prophylaxis with 1,800 cGy cranial irradiation on standing height growth of children with acute lymphoblastic leukemia (ALL). Seventeen longterm survivors (DFS over 5 years ) of ALL and Non-Hodgkins Lymphoma who had been admitted at pediatric department of Inje University Seoul Paik Hospital from January 1982 to September 1988 were studied. The long term survivors were divided into two groups by prophylactic treatment modality; intrathecal chemotherapy alone (Group I, 7 cases), intrathecal chemotherapy with cranial irradiation (Group II, 10 cases). The heights of each groups were compared normal standard growth of the sane aged children by mean SD score (The SD score was calculated with the use of the following formula). SD score=(x-x)/SD (x; height measurement, x; mean height for age of the normal population SD; standard deviation). The results were as follows; 1) The mean SD scores of Group I and Group II at diagnosis were -0.30 and -0.17, which were smaller than height of normal child. 2) In Group 1, the mean SD scores after the end of treatment were -0.14 of 1 year, 0.03 at 2 years and 0.01 at 5 years, which suggests that were normal height velocity and catch-up growth in these patients (P<0.05). The height of 1 year after the beginning of treatment were particularly smaller than that of the normal children (P<0.05). 3) The mean SD scores 5 years after the end of treatment were 0.10 in Group I and -0.17 in Group II, which shows strong tendency to statistical difference among these two groups. If larger numbers of patients are evaluated, it, however, may turn significant. In conclusion, 1,800 cGy cranial irradiation in ALL children significantly affects on height growth. We recommend to evaluate growth hormone for patient with 1,800 cGy cranial irradiation and to treat them with growth hormone.

High dose intravenous gammaglobuline (IVLG) therapy is effective in some of the autoimmune diseases. Although the exact mechanism of action of IVIG is uncertain, the action as a neutralizing antibody against unknown etiologic agents, the action of blocking of Fc receptors of effector cells, or the action as a antiidiotypic antibody are suggested. We report a case of 12 year old girl with systemic juvenile rheumatoid arthritis who was treated with high dose IVIG and got a remission. In August 1990 she was admitted to our hospital. because of intermittent fever, transient rash and multiple arthralgia. Under the diagnosis of systemic juvenile rheumatoid arthritis, aspirin (4.0g/day) had been given with symptom improvement. She was readmitted in October 1990 because of aspirin intoxication and acute fulminant hepatitis. She was discharged after recovery and any medicine was not prescribed. In November 1990 she was admitted because of epigastric pain, vomiting, intermittent fever, multiple arthritis, and mild hepatomegaly. Total parenteral alimentation had been given under the diagnosis of superior mesenteric artery syndrome and gold sodium thiomalate (Myochrysine, 5 and 10 mg, two weekly IM injection) was given in conjunction with prednisolone (30 mg/day) and naproxen (375 mg/day). She was admitted again in February 1991 due to the fever, coughing, rash, and hepatosplenomegaly. Pneumonia and leukopenia (2100/mm(3)) were found and gold sodium thiomalate injection was discontinued. Gammaglobulin 1 g/kg/day was given intravenously for 2 consecutive days with dramatic symptom improvement. Five more monthly IV gammaglobulin had been given and the side reaction of injection were nausia, fever, and headache which were controlled by the decrease of infusion rate. Four months after the last IVIG injection she had no symtom of arthritis and the hepatosplenomegaly was decreased. Hemoglobin level was increase to 12.2 mg/dL form 6.2mg/dL and ESR was decrease to 15mm/h. The oral prednisolne and ibuprofen were stopped one year after th last IVIG injection. All the laboratory parameters of arthritis and physical examinations had been normal for more than two year after the stop of all the medications until March of 1994. We suggest that high dose intravenous gammaglobulin can be one of treatments for severe systemic juvenile rheumatoid arthritis.

BACKGROUND: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. METHODS: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6-mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. RESULTS: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. CONCLUSIONS: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

Open long bone fracture is frequently difficult to reduce and maintain, especilly when there is extensive soft tissue damage. Infection, instability, malalignment and soft tissue complication often result in prolonged mobidity or failure. The Hoffmann's apparatus have merits, that can easily correct distracted, angular or rotational deformity of fracture site during early post-operative period, and stable fixation facilitates easily to the care of soft tissue injury. In addition, the affected limb can be elevated with balanced suspension, possible early exercise of neighboring joints. But we have exerienced some problems during treatment of fracture with Hoffmann's transfixation method. From February 1980 to December 1981, Hoffmann's transfixation method was employed in treatment of twenty-one patients that considered to have a poor prognosis with conversional forms of treatment. The results were obtained as follows; 1. For correction of distracted, angular, or rotational deformity, the fracture site should be reduced accurately. 2. Hoffmann pins should be transfixed as one plane and parrallel to each other. 3. Rigidity of fixation can be increased by increasing number of pins, actually three or more pins should be applied at each fragment of fracture. 4. Hoffmann's apparatus is more complex for management, more expensive and requires skillful technique compared with other external fixation apparatus. 5. The lateral view of fracture site could not be confirmed accurately due to overlapping of Hoffmann's adjustable connecting rod and bony shadow. 6. The main cause of injuries was due to traffic accidents in 17 cases (81%), involving tibia in 18 cases, femur in 2 cases and humerus in 1 case. 7. In the sixteen cases which could be assessed, the average times for external transfixation was 13.9 weeks and then followed by early weight bearing with P.T.B. cast or brace. The average time of bony union was 26.4 weeks. 8. The final result was excellent in 7 cases, good in 5 cases, acceptable in 3 cases, poor in 1 case.

The new trial to apply the closed I-M nailing for 23 cases of long bone fracture has been used our department, loss of hematoma, further damage to periosteum and soft tissue were prevented; the risk of infection was reduced; and the early functional use of extremities without additional superflous external fixation could be made. The results obtained were as follows; 1. There was no case of non-union or other complication. 2. The average bone union rate was 26.1 weeks in femur, 22 weeks in tibia, or 11.5 weeks in forearm. 3. The advantages is simple method and be able to do early ambulation without following muscular atrophy or ankylosis. 4. The patients were satisfactory about cosmetic problem after operation. 5. The merits of this operation were the short hospitalization and early adaptation of social activity. 6. In conclusion, closed I-M nailing is method of choice for long bone shaft fracture when internal fixation is indicated and our operative is useful and simple.

For developing the Group Health care system, health managers' job structure were analysed in the aspects of content, amount, and process. As a trial research, data were collected by a standardized job analysis table to 6 doctors, 40 nurses, and 11 industrial hygienists of Group Health Care System. Health care managers were performing complex and intellectual jobs such as health education for workers, managing health care, conference as well as more simple jobs like as filling diary. Especially, job was consisted of general job and health care management job in the proportion of 1:2.18. The major general job were data management related with the health statistics, and major health care management jobs were managing health care, health counselling, environmental management of working sites. Each specific jobs were required differentiated intellectual capacity, creativity, autonomy, psychic stress, and physical work; most respondents perceived that health care management jobs should require more inputs than general jobs Additionally job satisfaction and perceived need on specific job items were analysed. Results of this research, suggested through the field experiences in working sites, should be considered for improving the Group Health Care System.

One hundred sixteen C57 BL mice were painted with either 8-MOP, 5-MOP or TMP solution in concentrations of 0.02%, 0.1%, and 0.5% each and UVA irradiated. Skin biopsies were performed at 1, 3, 5 and 7 weeks after LJVA irradiation. The results measuring the number, area, and perimeter of the melanocytes after topical PLJVA were higher in the TMP-painted group than in the 8-MOP or 5-MOP painted groups. In all groups, the weekly changes showed an increasing value through five weeks. In comparing the drug concentrations used, 0.1% of chemicals produced the same or higher values than 0.5%. There have been few studies on the effects of 5-MOP in photochemotherapy. In tho study 5-MOP produced a pigment-producing effect similar to 8-MOP. Therefore, if topical PIJVA with 5-MOP is used in clinical practice, we could expect a significant therapeutic effect in vitiligo.

ACL plays an important role in stability of knee joint and its injury causes instability of joint which is known as the initiation of problem knee. Reconstruction of the anterior cruciate ligament would be preferred to the primary repair in treatment. And recently with the advance of arthroscopic technique and development of bone-patellar tendon-bone (BPB) graft material, the result of reconstruction is somewhat superior to that of primary repair. Authors compared the results of 20 primary repairs (Group I ) and 20 reconstructions (Group II) among 64 acute ACL injury treated Sung-Ae General Hospital from January 1989 to December 1994. The results were as follows: 1. Most common associated injuries were medial collateral ligament rupture and medial meniscal tear. 2. Group I showed postoperatively 13 negative anterior drawer test, 12 negative Lachmann test and 12 negative pivot shift test and group II showed postoperatively 17 negative anterior drawer test, 15 negative Lachmann test and 17 negative pivot shift test. (p<0.05) 3. In postoperative Lysholm knee scoring scale, group I showed 86 points and group II showed 93 points (p<0.05). 4. In postoperative KT-1000 arthrometer, 12 cases in Group I and 16 cases in Group II showed less than 2mm difference with sound side (p<0.05).

Usually, fractures of the humerus can be expected to unite. Circumstances often predisposing to nonunion are open reduction and internal fixation, infection, soft tissue interposition between fracture fragments and inadequate external immobilization. The effectiveness of various methods of treatment and the complication was discussed. The best results are achieved in cases treated by compression plates and iliac bone graft. Total 21 cases of nonunion of shaft of humeral fractures from Jan., 1980 to Dec., 1986 were treated at the Department of Orthopedic Surgery of Soon Chun Hyang University Hospital. The results were as follows ; 1. Incidence of nonunion of humerus shaft among the 270 cases has 7.8%; rates of non-union was 5.4% with nonoperative treatment of fractures of humeral shaft and 10.5% with operative methods. 2. Of 21 cases, male between 20–40th age group was predominant and mean age was 36 years. The cases of fracture was mainly due to the car and machinary accident. 3. Prevalent type and site was lower 2/3 transverse fractures. 4. There were associated injuries in ipsilateral upper extremity in 12(52%) patients. 5. The probable causes of nonunion were complex; 9 of inadequate internal fixation and fixation metal failure, 7 cases of poor external fixation, 3 cases of soft tissue interpostion between fracture fragments and 2 cases of infection. 6. The treatment performed were somewhat variable to include open reduction and plate (DCP) fixation for 18 cases, open reduction and circlage wiring for 2 cases and open reduction and screw fixation for 1 cases. All were supplemented with autogenous iliac bone graft. 7. Postoperative immobilization was done with shoulder spica cast, abduction splint and long arm cast for average 6.5 weeks. 8. All were united at average 4.7 months. Transient radial nerve palsy in 2 cases, and limitation of motion of shoulder and elbow iri 2 cases, which required considerable time of physical therapy, but postoperative infection was none.

This study examined effect of preceptorship on clinical education of senior nursing students of Y. University in Seoul. Quasi-experimental study design was used. Sixty students of pre-test and 80 of post-test participated in this study. Competency scores of the students before the clinical education(pre-competency scores) were compared with the competency scores after the clinical education(post-competency scores), and teacher evaluation scores between preceptors and clinical the data from students with preceptors(experimental group, N=22) and with clinical instructors(comparative group, N=58) were also examined. Study results indicated that the total post-competency scores were higher compared to the total pre-competency scores, and the difference was statistically significant. Among 7 sub-domains, differences were all statistically significant in 6 sub-domains except "self-esteem" domain. Competency scores of the students who had clinical education with had clinical education from clinical instructors. But the difference between those scores was not statistically significant. However, students gave higher evaluation scores to preceptors than clinical instructors. This study concluded that preceptorship did not influence much on clinical education at this time yet. However it is expected that when preceptors adjust their new roles and function them in expert education. This study recommended that for the preceptors to increase their motivation to teach students and to accept their roles, systemic rewards are needed.
