Herniated intervertebral disc(HIVD) of the lumbar spine has been known to be relatively uncommon in the teenager and frequently be associated with trauma. However, with the changing life style and increasing sports activities, and most of all, with the advent of new imaging modalities, the incidence seems to be increasing gradually. In order to define the characteristic pattern of HIVD of teenager in the era of MRI, and to clarify the associated lesions, such as apophyseal ring fractures, authors performed this retrospective study in 55 teenager patients with HIVD(77 discs), in which MRI was used as main diagnostic modality. The following results were obtained 1) The incidence of the HIVD in teenager was 9.6%(55 patients) of total HIVD patients(575 patients) for 4 years from December 1989 to December 1993. 2) According to MRI findings, HIVD of the teenager could be classified into 3 distinct patterns; simple HIVD, lumbar apophyseal ring fracture(LARF), and vertebral rim lesion. 3) In simple HIVD, as for the MRI classification, protruded type was most frequent type and there was no sequestered type 4) In LARF, the incidence was 14.4% of teenager's HIVD and posterocephalad margin of L5 was the most common site of involvement. 5) Exophytic bony protrusion from the posterior margin of vertebral body, which we called vertebral rim lesion, could be defined on MR sagittal view in 6 cases.

There are many options for the management of osteoarthritis of the knee joint. Recently, arthroscopic surgery has been added to the armamentorium of the treatment modalities in osteoarthritis of the knee which does not respond to conservative treatment. Among 74 arthroscopic pocedures(including partial menisectomy, removal of loose bodies, synovectomy, cartilage drilling and simple lavage) done for osteoarthritis of the knee, 68 patients studied at average 3.1 years after procedure and the results were as follows 1. Seventy-one percent of patients had at least 2.5 years or more relief of pain and symptoms. 2. Fifty-six percent were still good at follow-up of 3.1 years. 3. The best result were obtained after removal of loose bodies and resection of unstable flap tear of a meniscus in association with mild osteoarthritis. 4. The poor result were obtained in patients with severe degenerative changes of both femoral condyle, 5. The results were much better in the normally aligned knee compared with valgus knee.

Fetal cystic hygroma is a rare congenital malformation of the lymphatic system appearing as a single or multiloculated fluid-filled cavity, most often in the neck. A case of fetal nuchal cystic hygroma was diagnosed by Ultrasonography at 22 weeks of gestation and the diagnosis was confirmed at autopsy. We present the case with a brief review of literature.

BACKGROUND: Skin surtice lipids increase and decrease in tints with acne vulgaris and in patients with atopic dermatis, respectively. Notably, hydratior. in decreased in patients with atopic dermatitis. Clinically it is common for the two diseases to occur together. OBJECTIVE: We would like to find out the rate, clinical cteristics, and hydration and lipid levels when acne vulgaris and atopic dermatitis concur. METHODS: We classific the clinical levels and measured the hydration and lipid levels of the face and forearm area of patients with acne vulgaris, patients phatopic dermatitis, and patients with both diseases, who visited the Youngdong Severance Hospital. RESULTS: 1) 13.8% (14/102) of patients with acne vulgaris had at, epidermatitis. 31.1% (14/45) of patients with atopic dermatitis had acne vulgaris. 2) Patients with acne vulgaris had increased lipid levels and normal hydration levels. 3) Patients with atopie dermatitis had decreased lipid and iylration levels. 4) Patients withoth cnevulgaris and atopic dermatitis a no severe grade of acne vulgaris, and showed decreased hydration but normal lipid levels. CONCLUSION: In patients with both arne vulgaris and atoic dermatitis, clinically acne vulgaris was not severe and hydation levels were lower than normal controls.

To elucidate the effects of dimethyl sulfoxide on of myocardial and endothelial cells in culture, the cells were exposed to 10% dimethyl sulfoxide in culture medium for 1 hour at 48 hours after cell isolation. The general morphology and the cytochemical reaction of marker enzymes for mitochondria and Golgi complexes were investigated. The results were summarized as follows 1. DMSO induced elongation and narrowing of the cells and increase of mitochondrial reaction in myocardial cells. 2. DMSO induced destruction and disruption of myofibrils in myocardial cells resulting in increase of contractile activities. 3. In the endothelial cells, DMSO suppressed proliferative activities but thiamine pyrophosphatase reactions were enhanced indicating increase of Golgi complex activity. 4. DMSO seemed to hamper with the adhesiveness and motility of the endothelial cells causing the decrease of the number of cells in vitro.
