The posterior cruciate ligament has been considered the basic stabilizer which performs important functions because of its location and orientation within the knee joint. Therefore, failure to recognize or to repair its tear results in a poorly functioning knee. An isolated injury to the posterior cruciate ligament is believed to be unconmon and is seen most commonly in association with other ligamentous injury and dislocation of the knee joint. But recently its injuries are of frequent occurrence because of increasing traffic accident and sports activities as football, soccer, and skiing. The authors experienced 12 cases of isolated posterior cruciate ligament injury from March, 1978 to February, 1982 at the Department of Orthopaedic Surgery, Capital Arrned Forces General Hospital and the results were as follows: 1. The most common cause of injury was passenger traffic accident (5 cases) and followed by soccer (4 cases), football (2 cases), and skiing (1 case). 2. There were 3 causative mechanisms by which the posterior cruciate ligament was injured; anteroposterior force on the front of the knee joint (5 cases), hyperextension of the knee joint (4 cases), and posteriorly directed rotatory force (3 cases). 3. Tears of the posterior cruciate ligament occured at its tibial attachment (5 cases), with avulsion of a bone fragment at its tibial attachment (3 cases), at its femoral attachment (2 cases), and its mid-portion (1 case). 4. The major findings in this injury included giving-way or instability on walking, abrasion or contusion over the anterior proximal tibial surface, presence of a posterior drawer sign, sagging of the tibia, bloody effusion, and X-ray evidence of avulsion fracture. 5. One case was treated conservatively and 11 cases surgically using screw fixation and direct or pull through suture through a posterior S-shaped incision (5 cases), medial parapatellar and posterior S-shaped incision (3 cases), and medial hockey-stick incision (3 cases) and were immobilized in a long leg cast with 30 to 45 degrees of the knee flexion for 6 to 7 weeks. 6. The results evaluated by Apleys method were excellent in 8 cases; good in 2 cases, and fair in 2 cases.

This study was performed in order to evaluate the sero-epidemiological status of toxoplasmosis in pregnant Korean women. Among 5, 175 sera and 750 amniotic fluid samples obtained from pregnant women, 41 serum samples (0.79%) and 10 (1.33%) amniotic fluid samples tested positive for IgG antibodies by ELISA. Fifty one cases showing a score more than 0.25 on ELISA were tested for PCR reaction against the SAG1 gene. Only one case of the 51 ELISA positive cases exhibited a positive reaction on all tests. This case had a history of acute nephropyelitis during early pregnancy, but fortunately, had delivered a phenotypically healthy baby. In this study, the seroprevalence of toxoplasmosis in pregnant women was found to be comparatively low, consistent with previous reports from Korea. However our trials, performed with a variety of diagnostic tools, were considered to be useful for the precise diagnosis of congenital toxoplasmosis.

Entrapment of the posterior interosseous nerve is an uncommon syndrome characterized by an inability to extend the fingers and thumb. This entity bas become recognized increasingly since reported in 1966 by Capener and Muholland et al. The pathogenesis could be explained as an anatomical basis. And various cases were reported that trauma, local swelling, inflammation, postural and iatrogenic factors were concerned with the causes. In recent 4 cases of posterior interosseous nerve syndrome were experienced at Busan National University Hospital and following result were obtained.1l. Arcade of Frohse, fibrous band, recurrent radial artery are important compressive factors. 2. Surgical decompression led to an effective cure. 3. Tendon transfer is indicated after severe degenerative change.

Benign solitary osteochondroma are the most common benign bone tumor, and often arise in the long bone of the extremities about 80% of lesions, particulary about the knee and the upper extremity. In rare cases, the spine is involved. We describe a case in which a solitary sacral osteochondroma compressed the lumbosacral plexus, producing sensory disturbance. The tumor was removed through the anterior midline approach. The excised mass was round, lobulated, measuring 7. 5cm×6cm, pedunculated type and the cartilage cap is complete and is 4mm in thickness.

BACKGROUND: Herpes zoster(HZ), caused by reactivation of latent varicella-zoster virus, is manifested by dermatomal distribution of skin rashes, acute pain and post-herpetic neuralgia by pathologic involvement of the sensory ganglia. Low-energy laser(LEL) deliver a small amount of energy without elevation of the tissue temperature. LEL is reported to have various biologic effects such as anti-inflammatory, analgesic, regenerative, antiallergic, immunocorrective, and antibacterial effects. OBJECTIVE: We attempted to evaluate the therapeutic effect of LEL on an acute phase of HZ. METHODS: A total of 60 patients with acute HZ were enrolled in the study. The control group(30 patients) received medications including analgesics, antihistamine, and topical care without LEL irradiation. The experimental group(30 patients) were irradiated with LEL daily for 7 days in addition to the same kinds of medications for the control group. The efficacy of LEL irradiation for HZ was assessed by analyzing changes in skin rashes, pain scores, and postherpetic neuralgia.

Porokeratosis is a specific disorder of keratinization characterized histologically by the presence of a cornoid lamella. Clinically, the basic lesion is a sharply demarcated hyperkeratotic plaque which may be linear, punctated, or annular with central atrophy. The etiology of the various types of porokeratosis is unknown. However, heredity, UV radiation, immunosuppression, trauma, burns, and occult infection are known to be precipitating or exacerbating factors. A 32-year-old female was burnt on her right arm and chest at the age of 12. Several years later, brownish plaques developed in these burn areas. Seven years prior to visiting our clinic, nu- merous match-head sized, peripherally elevated macules developed on the forearms and have gradually spread to the other areas of her upper and lower extremities. The histological findings of two lesions from the burn areas showed the same features including cornoid lamellae in the epidermis and fibrosis in the dermis. Howerer, the histological finding of a lesion from a non-burn area showed cornoid lamellae in the epidermis without evidence of dermal fibrosis. We believe our case is the first to be reported in Korea in which porokeratosis arose in previous burn areas.

We herein present a rare case of a 42-year-old man with primary cutaneous marginal zone lymphoma(MZL) of the B-cell type on his shin. MZL is known to be the cutaneous counterpart of MALT(mucosa-associated lymphatic tissue) lymphoma. Histopathologically, MZL is characterized by multi-nodular infiltrates of centrocyte-like and centroblast-like marginal cells with bottom-heavy patterns, lymphoplasmacytoid differentiation, typical distribution of tumor cells in the marginal zone and follicular colonization by tumor cells. This B-cell lymphoma of a benign grade should be differentiated from mantle cell lymphoma and follicular center cell lymphoma.

Lupus erythematosus panniculitis is a rare variant of lupus erythematosus primarily involving a panniculus with or without discoid lupus erythematosus in the overlying skin. A 34-year-old woman showed multiple, variable-sized, indurated subcutaneous nodules on both her upper arms and axillae. A Histopathological examination revealed lobular panniculitis with infiltration of several hyperchromatic atypical large lymphocytes. The infiltrated cells were positively stained with LCA, UCHL-1, CD4, CD8, but not with CD20 and CD68. A T cell receptor -chain gene and immunoglobulin heavy chain gene rearrangement study showed no monoclonality. The result of an ANA test was positive at 1: 40 in a homogeneous pattern. Skin lesions were improved by combined therapy with daily hydroxychloroquine 400mg and prednisolone 10mg in a week and after 6weeks, resolved with atrophic depressed scars. After 4 months, she complained of symptoms of the Raynaud phenomenon and was managed by nifedipine. There has been no recurrence during follow-up for 7 months.

A case of glioblastoma multiforme, arising in the right temporal lobe in a child was operated in our hospital. The patient was a 11 years old boy, who was well after the radical removal of the tumor with concomitantly performed internal decompression. The operative method, post-operative prognosis, and literatures were reviewed.
