Two cases of congenital multiple joint laxity are reported here. One was a 18-year-old boy, in whom the hypermobility of the joints was striking that 4 criterias (Carter & Wilkinson, 1964) could be observed. The other was a 18-year-old male who showed positive findings in three of the five diagnostic criterias. In both no familiar occurrence was noted.

The simultaneous bilateral spontaneous pneumothorax is very dangerous, so the chest drain insertion should be done urgency. Contrary to the unilteral pneumothorax, the patient with simultaneous bilateral pneumothorax complains a severe respiratory distress, cyanosis and chest pain without the tension pneumothorax. Now, we present two cases of the simultaneous bilateral pneumothorax. The prompt insertion of chest drains relieved symptoms. One case is resolved by the bilateral thoracotomy, the other by the insertion of chest drains only.

The chronic paranasal sinusitis are caused by various orign such as dental, general and anatomic problem. Among them, the odontogenic maxillary sinusitis which concerned by cral & maxillofacial surgeon have been treated by medicine, conservative treatment such as endodontic treatment, and Caldwell-Luc operation. But, New technique, so called Functional Endoscopic Sinus Surgery, have recently been performed in the ENT dept. This technique have the mechanism that widening maxillary ostium through removal of involved nasal mucosa and adjacent tissue accelerates adequate drainage and regeneration of normal mucosa and have merits such as minimum morbidity and complication. So, we would report one case, 22 years old female, of 3 patents who were diagnosed as odontogenic maxillary sinusitis and treated by Functional Endoscopic Sinus Surgery and Apicoectomy, and had good results.

BACKGROUND: Desmosomes are adhesive intercellular junctions that form an important component of the junction complexes of epithelial cells. They provide intercellular links between the intermediate filament cytoskeletons of adjacent cells and are thus involved in maintaining the structural integrity of tissues. OBJECTIVE: Calcium and retinoids are major regulators of epidermal differentiation and their role on keratin proteins are well known. However, their effects on desmosome moleucles are unknown. To address this question we initiated a study of the effects of these epidermal differentiation regulators on desmosomal components, i.e., desmoplakin, desmoglein, and pemphigus antigens. METHODS: We used monoclonal antibodies against desmoplakin(DP) and desmoglein(DG), and sera from patients with pemphigus vulgaris(PV), pemphigus foliaceus(PF) and paraneoplastic pemphigus (PNP) to study the effects of calcium and retinoic acids, which are major regulators of epidermal differentation, on desmosomal protein formation in human cultured deratinocytes. We performed immunofluorescence, immunoblotting and immunoprecipitation study using human keratinocytes cultured in high calcium media with or without retinoic acid and in low calcium media with or without retinoic acid. RESULTS: 1. In low calcium (0.15mM) media, PV antigen and DG were produced in a small amount and it appeared that these desmosomal proteins were located in cytosol. Whereas in high calcium (1.8mM) media, production of these desmosomal proteins was increased not they were assembled at the desmosomal structures located in cell-cell contact margins. 2. PF antigen, which was identical to the DG, were not produced or expressed in cultured keratinocytes even when cultured in high calcium media. 3. PNP antigen and DP were produced in cultured keratinocytes grown in both high low calcium media but their production was increased in high calcium media and only in high calcium media they were assembled at the desmosomal structures. 4. Retinoic acids induced loosening of cell-cell contacts of cultured keratinocytes and decreased the production of desmosomal proteins. CONCLUSION: Our results suggests calcium is a major regulator of the production and assembly of desmosomal proteins including pemphigus antigens, but PF sera and monoclonal antibodies against DG show different antigen binding characteristics. It appears that retinoic acids inhibit production of desmosomal proteins.

Peripheral longitudinal tears of the menisci in nine patients(eight men and one woman) were repaired by arthroscopic techniques from December 1985 to November 1986. Six lateral and three medial menisci were repaired. The results of the repairs were classified by Tapper and Hoover scale as excellent 2, good 4, fair 2 and poor 1. The aversge durstion of follow up was 17.6 months(range : twelve to twenty-four months). One patient had a rerupture and two patients had hemarthrosis. The repairs of peripheral meniscal tears hsve been shown to be an effective and successful procedure. Arthroscopic instruments and techniques have been improved to allow for the repair of some of these tears.

The case of a 56-year-old woman with a keratoacarithoma(KA) of the labial mucosa is herein reported, The tumor was excised and the pathological features were characteristic of a KA, This case is reported because the oral mucosa is such an unexpected location for solitary KA and the labial mucosa of this patient received chronic actinic damage, which suggested an etiological relationship. Follow-up examination of the patient after four months showed no recurrence.

Multiple satellite pyogenic granuloma developed on the left upper back of a 14-year-old boy after excision of a hemangioma-like lesion. He has had nevus flammeus on the left upper arm since birth with fine linear telangietasiae around the main lesions. Histopathology showed the capillary proliferation in the dermis, and transmission electron microscopy revealed multiple Weibel-Palade bodies, considered an early endothelial cell marker, in the cytoplasm of the endothelial cells. We believe this patient may have the propensity to develop different angiomatous lesions.
