A hospital-based, matched case-control study was carried out to evaluate the relation ship of various suspected risk factors including snoring and serum level of cholesterol to cerebrovascular disease in Korea. A total of 127 incident cases of cerebrovascular disease(74 cases of cerebral infarction and 53 cases of intracerebral hemorrhage) admitted to the department of neurology in a university hospital from December, 1993 to March, 1995 were compared with 127 matched controls admitted to same hospital in same period. A multivariate analysis suggested that ECG abnormality(left ventricular hypertophy and atrial fibrillation), family history of cerebrovascular disease, fundoscopic abnormality, previous history of transient ischemic attack and hypercholesterolemia were risk factors of cerebrovascular disease. ECG abnormality, fundoscopic abnormality, smoking and hypercholesterolemia were also suggested as risk factors of cerebral infarction.

Backgrounds: Thyroid hormones play a fundamental role in the initiation and maintenance of somatic growth in mammalian species, and the insulin-like growth factors(IGFs) occupy a position of central importance in the growth of all tissues. To evaluate the changes in serum insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding proteins in hyperthyroid and hypothyroid patients, sera was obtained from 19 hyperthyroid patients, 9 hypothyroid patients, and 10 healthy volunteers. Methods: IGF-I concentration was determined by radioimmunoassay, and changes in IGFBPs were assesed by Western Ligand Blotting. To evaluate the binding pattern of IGF-I & IGFBPs, autoradiographs were obtained. Results & Conclusion: IGF-I levels were increased significantly in hyperthyroid patients(mean ±SE, 267.88±9.80 ng/ml, p<0.05) and decreased significantly in hypothyroid patients(154.81±1.43 ng/ml, p<0.01) compaired to healthy control group(209.45±.60 ng/ml). Autoradiograph of serum IGFBPs from patients with hyperthyroidism and hypothyroidism did not show any change in the intensity of IGFBP-3 bands(40-45 KD) and IGFBP-1 bands, but in hyperthyroid patients, it showed increased intensity of IGFBP-2 band compared to healthy control group and hypothyroid patients.

A 21-year-old woman, who had a one-year history of pancytopenia with histiocytic necrotizing lymphadenitis and hepatosplenomegaly, presented with a 5 day history of tense bullae, which were localized on the face. These clusters of tense bullae occurred on clinically normal skin, she did not have other skin lesions. A diagnosis of bullous systemic lupus erythematosus (BSLE) was established based on clinical, laboratory, histological, and immunological findings. The bullae showed good responses to dapsone (100mg, daily) and resolved within 10 days with-out scaring. Bullous lesions of SLE may be the first cutaneous manifestation in some patients with SLE and should be considered in the differential diagnosis of the other subepidermal bullous disorders.

It is difficult to treat the complete cleft lip because of wide cleft and malaligned alveolar process, outward rotation of greater(medial) alveolar segment, and severe nasal deformity. Lip adhesion without presurgical orthopedic appliance was performed on 8 consecutive infants with unilateral complete cleft of the primary palate before denfinitive lip repair with Millard I procedure. Among 8 patients, 6 patients had complete unilateral cleft lip with alveolar cleft only and 2 patients were accompanied with complete cleft palate. All patients had more than a 10-mm-wide lip cleft with alveolar arch discrepancy. Lip adhesions were performed at 1-2 months of age and definitive repair was done at 5-6 months of age. Lip adhesions were performed by Randall's method and cheiloplasty was done by Millard I technique. Satisfactory results of lip and nose were obtained aesthetically in 8 cases after an average follow-up of 32 months. The vertical height of the medial and lateral lip segment were a symmetric appearance, while the vermilion tubercle, philtrum, and Cupid's bow were natural. Disadvantages included increased operating time and the sacrifice of same-lip tissue. In conclusion, preliminary lip adhesion can have better functional, esthetic and emotional results since the disadvantages are minor compared to the advantages.

Endoscopic technique have become very popular in plastic and reconstructive surgery. They have provided advantages over previously closed techniques by minimizing scars, soft tissue manipulation and access with excellent visualization and magnification. More than twenty cases of facial bone surgery were performed over the past 3 years by endoscopic assistance. Our series consist of 3 cases of frontal bone contouring, 1 zygoma contouring, 3 fracture of zygoma, 9 fracture of orbit, 4 rhinoplasty for deviated nose. To accomplish this technique, a rigid 4 mm, 30 degree down angled endoscope was used. The frontal bone or zygomatic arch is approached endoscopically through two or three small incisions on the temporoparietal scalp. All endoscopic instrument are then manipulated through these incisions. The approach for zygoma complex, maxilla and mandible needs intraoral incision. Recontouring by a power bur and osteotomy using a small saw are done with endoscopic visual assistance. Rigid fixation requires an additional small incision over the plate for trocar method. The other technique was same with routine standard rhinoplasty procedures. The duration of follow-up ranged 3 months to 27 months. The postoperative course were satisfactory with fewer complication than conventional technique. The extra-time need for the endoscopic procedures was about 1 hour Endoscopically assisted facial bone recontouring, osteotomy and plate fixation can be performed with adequate visualization and direct manipulation of all facial bone. Complications usually associated with extensive incisions and pool visualization may be avoided. This technique may prove to be ideal for aesthetic surgery for facia skeleton with smaller scars and less morbidity.

We experienced a case of simple pneumonediastinum showing the findings of pleural effusion. Frontal chest radiography showed not only pneumomediastinum but also diffuse haziness with sharp medial margin on left lower lung field, blunting of costophrenic angle, and indistinct contour of diaphragm simulating pleural effusion. CT scan confirmed that these findings arose from the displaced pleura and the associated compression atelectasis by loculated air on the anterior mediastinum.

The cutaneous synthesis of vitamin D in response to ultraviolet radiation exposure is the most important factor in maintaining vitamin D balance in Man. The skin is not only the site of vitamin D synthesis, but also a target organ for calcitriol(1, 25-dihydroxy-vitamin D) which is naturally occuriag, hormonally active form of vitamin E. It is now known that calcitriol inhibits the proliferation of epidermal cells and induces her differentiation. In this study, epidermal keratinocytes and melanocytes were isilated from the neonatal foreskin, and were culturod using a MCDB 153 and modified TIC media, respectively. And then various concentratioris of calcipotriol(MC 903), a synthetic aralogue of calcitriol, were added to each culture. The effects of calcipotriol on the growth of human keratinocytes and melanocytes were investigated. The results were as follows : 1. The addition of calopotriol to human keratinocyte and melalocyte cultures inhibited their proliferation in a dosdependent manner. 2. Calcipotriol had no effects on the melanization process of the melanocyte. 3. Calcipotriol was found to inhibit the proliferation, however it induced the terminal differentiation of cultured keratinocytes, as judged by morphologicai changes. The decreased density of kerationcytes, The formation of cornified cells, and the cellular destruction in a concentration of 10 M of calcipotriol were observed. 4. By using the light atid the electron microscope, we observed that the epidermal thickness was decreased and terminal differentiation was facilitateir. Living Skin Equivalent (LSE) according to the increasing concentration of calcipotriol. A]i)parent cytotoxic effects were observed in 10 M, 10 M of calcipotriol. In summary, the above results indicate that the addition of calcipotriol to the in vitro culture system of human keratinocyte and melanocyte induces the biologic process of terminal differentiation of keratinocytes and inhibits proliferation of keratinoytes and melanocytes in a dose-dependent manner.
