Six. patients with clavicular nonunion were treated at the Daegu Catholic Hospital from Aug. 1980 to Jun, 1986. Five patients were male and one was female, and their ages ranged from 35 to 52 years. There were hypertrophic nonunion in four patients and atrophic nonunion in two patients; all six patients had symptoms due to nonunion. Factors that might have influenced the development of nonunion in our cases seem to be inadequate operative treatment, severe trauma and inadequate external fixation due to combined injuries. Five patients were treated with semitubular plating and iliac graft, and one was treated with intramedullary K-wire fixation and iliac graft. All patients achieved good union by average 10 weeks postoperatively and symptoms disappeared. It was concluded that symptomatic nonunion of the mid-clavicle could be treated by operation, and the procedure of choice seemed to be rigid internal fixation with plating applied in compression and bone graft.

In 38 patients with femorsl neck fracture trested at Cstholic Hospital from Aug. 1980 to Jun. 1985, 24 patients were followed for more thsn 2 years. Preoperative bone scanning with 99m Tc MDP was performed in those 24 patients and postoperative follow-up bone scan assesment of the femorsl vascularity was done in 9 patients of them. Following results were obtained. 1 . Tc 99m methylenediphosphonate bone scanning was effective in assesing the femoral head vascularity in the femoral neck fracture patients. 2. The femoral head activity could be changed in the postoperative scanning : there could be further injury to the blood supply during operation or femoral head revascularization after operation 3. Some information about the possibility of future avascular necrosis could be obtained by comparing preoperative and postoperative bone scan in order that early preventive measures might be applied against the late head collapse. 4. It was conculuded that internal fixation should be considered first in the treatment of fresh femoral neck fracture : the indication of head replaement surgery could not be rnade by preoperative bone scan only.

A 23-year-old man had multiple small, skin-colored firm papules on the both sides of the nasolabial folds since the age of approximately 17. His mother had a similar skin lesions on her face. The histopathological findings of skin biopsy specimens from patient(son) showed horn cysts consist of a fully keratinized center surrounded by basophilic cells and tumor islands composed of basophilic cells arranged in a lacelike or adenoid network and occasional solid aggregates and there are also a foreign body giant cell reaction in the vicinity of the ruptured horn cysts.

Endoscopic ACL reconstruction using bone-patellar tendon-bone has been considered the gold standard in the field of reconstructive ACL surgery. Technically, graft must be placed at isometric point. But it is difficult to evaluate the placement of graft postoperatively. The purpose of this study is to determine the radiological ideal position of graft by comparing postoperative results with the graft placement. Seventy cases of endoscopic ACL reconstruction were reviewed and classified according to the femoral and tibial graft position on radiologic imaging. The femoral graft position was classified in relation to angle of graft on anterior position view and distance from posterior margin of graft to the inner surface of posterior cortex on lateral view. The tibial graft position was classified in relation to intercondylar eminence on anterior posterior view and lateral view. Knee score (modified Marshall, Lysholum), manual anterior instability test (Lachman test, Pivot shift test) and arthrometer measurement were checked to evaluate postoperative results in each case. The results of this study implicate that knee joint in which femoral graft was oriented at direction of 11 o clock centring around 68 degree respect to tibial joint and placed within 3mm from posterior cortex showed higher knee score and lesser laxity. In cases of tibial side, the graft oriented to intercondylar eminence (AP view) and placed anterior to intercondylar eminence (lateral view) showed higher knee score and lesser laxity.

BACKGROUND: Handgrip and cold pressor test may increase the afterload of the heart. And in left ventricular hypertrophy, it is known that mitral flow pattern is affected by decreased left ventricular compliance. We investigated the effects of handgrip and cold pressor test on mitral flow pattern in patients with left ventricular hypertrophy. METHODS: Handgrip and cold pressor test were performed in 12 subjects with left ventricular hypertrophy and in 14 healthy normal subjects. In supine position, blood pressure, heart rate and Doppler echocardiographic parameters(early peak flow velocity : E, atrial peak flow velocity : A) were obtained at rest, 1 and 3 minutes after the onset of tests respectively. RESULTS: In both groups, handgrip and cold pressor test increased blood pressure slightly without a statistical significance. In left ventricular hypertrophy group, there were significant increments in heart rates at 1 minute of handgrip (78+/-12min-1, p<0.001) and cold pressor test(77+/-7min-1, p<0.05) as compared to that at rest (73+/-12min-1). Mitral flow velocities did not show significant change after the tests in control group. A waves after 1 minute of handgrip(85.2+/-18.4cm/sec, p<0.05) and cold pressor test (87.3+/-17.8cm/sec, p<0.001) showed significant increases as compared to that at rest (79.1+/-14.9cm/sec) in left ventricular hypertrophy group whereas E waves did not. CONCLUSION: Although handgrip and cold pressor tests did not affect the mitral flow significantly in control group, each test raised A waves in left ventricular hypertrophy group. These results suggest that increased A waves may be due to a rise in afterload and decreased left ventricular compliance caused by handgrip and cold pressor test in left ventricular hypertrophy group.

We present a case of mycosis fungoides of an 52-year-old woman who showed multiple pruritic erythematous papules, plaques with ulcers on the trunk, extremities and face. Her skin biopsy specimens were studied irnmunohistochemically with, monoclonal antibodies against T cells(80%, Leu-4, OKT11), T-cell subsets (60% Leu-3a, OKT4a, 40% OKT8) and Langerhans cell(OKT6). We think that this case should be considered in the differential diagnosis of adult T-cell leukemia/lymphoma. The proliferating cells were negative for anti-Tac.

Using peanut agglutinin(PNA), neurarninidase, and avidin-biotin peroxidase com plex(ABC) technique, normal skin specimens, nevocellular nevi, and malignant melanomas were studied, and different PNA binding patterns between nevocellular nevi and malignant melanomas were observed. The results were as follows : 1. In normal skin, except the basement membrane, epidermis and hair follicle epithelium showed a cell membrane staining of PNA after neuraminidase pretreat ment. Sebaceous glands revealed membranous and cytoplasmic staining of PNA, but sweat ducts were not stained. 2. In nevocellular nevi, none of the nevus cells were stained with PNA aftet neuraminidase preteatment. 3. In malignant melanomas, all of the melanorna cells were stained along the cell mernbrane with PNA after neuraminidase pretreatment. Therefore, the PNA staining after neuraminidase pretreatment on paraffin embedded sections using ABC technique is considered to be a useful probe for the differentiation between malignant malanoma and nevocellular nevus.
