Open fracture characteristically has higher chances of infection and sof tissue damage in comparison with closed fracture. In spite of the development of operation methods and antibiotics, complications such as infection, nonunion, delayed union, and joint stiffness are continuously confronted as problems in the field of orthopedics. Different methods of treatment have been advocated as regards the care of the open wound and the method of stabilization of the fracture fragments. Therefore a comparative analysis of the type of open fracture and the bone union time according to the initial treatment methods was made from 47 cases over the age of 20, who were followed up until bone union developed among the inpatients who were treated for open fracture of tibia in the period of 7 years from January, 1982 to December, 1988, and the results are as follows: 1. The highest incidence of fractures was encountered in 3rd decade(34%) and male to female ratio was 6:l. 2. The most common cause of fractures was traffic accident(76.6%). 3. The most common level of fracture was in mid one-third and the bone union time was longest in mid one-third. 4. The bone union time was longer, and the rate of complication was greater in order of type 1, 2 & 3 according to Gustilo's classification. 5. The good result was obtained in type 1 fractures, by using the closed reduction & cast immobilization and pin & plaster method; in type 2, the bone union time was shortest in the cases of pin & plater method; in type 3, the bone union time was shortest in the cases of closed reduction or open, reduction & external fixation. 6. Bone union was obtained in all cases of delayed union and nonunion and the bone union time was shortest in cases treated with plate & bone graft.

Pleomorphic xanthoastrocytoma is histologically characterized by marked cellular pleomorphism of lipid-laden neoplastic astrocytes and bizarre giant cells showing mitotic figures and high cellularity. Inspite of its ominous-looking microscopic features, howerver, the prognosis is usually favorable. This tumor develops mainly in the supratentorial area of young people and frequently involves the leptomeninges. We experienced a case of pleomorphic xanthoastrocytoma in 18 year-old-male. In addition to the cellular pleomophism, the prominent reticulin fibers surround the individual tumor cells or the tumor cells nests. Immunohistochemical staining and electron microscopy revealed glial fibrillary acidic protein(GFAP) expression and pericytoplasmic basal lamina in the tumor cells.

Colon has the highest bacterial concentration in the gastrointestinal tract. When the colon is perforated, the operator has to decide whether to perform primary closure, resection with anastomosis, proximal colostomy, and exteriorizatoion. In this retrospective study, from October, 1993, through July 1998, 56 patient with panperitonitis due to colon perforation were operated at Ewha womans University medical center. The rectal perforation was limited the intraperitoneal portion. Our cases were divided into two groups. Group I included 34 patients who treated with one step operations of primaryrepair or resection anastomosis. Group II included 22 patients who treated with two step operations of proximal colostomy or exteriorization. The one step operations were performed in 34 patients, proximal colostomy in 21 patients, and exteriorization in 1 patient. There was 13.7% in the incidence of motality and 33.3% in the incidence of morbidity. The Chi-square test was used to evaluate the significance of differences between two groups. Independent risk factors for adverse outcomes were compared and used to analyse the probability for adverse outcomes with respect to the mode of treatmen. The mode of treatment was not dependent on the risk factors. These results suggest that one could select positively primary closure or resection with anastomosis for the treatment of patients with panperitonitis due to colon perforation.
