Traumatic Brain Injury(TBI) of any severity can result in broad and persisting biopsychosocial sequelae. Depression after TBI occur at a greater frequency than in the general population, with estimates approaching 25% to 50% for major depression, and 155 to 30% for dysthmia. Acute onset depressions are related to lesion location and may have their etiology in biological response of the injured brain, whereas delayed onset depressions may be mediated by psychosocial factors, suggesting psychological reactions as a possible mechanism. Anxious depressions are associated with right hemisphere lesions, whereas major depressions alone are associated with left dorsolateral frontal and left basal ganglia lesions. However, there is insufficient information to postulate a specific neuroanatomic model for TBI-related depression.

During the period of 25 years from Apr. 1959 to Jan. 1984, 58 patients of non-tuberculous infec-tion of the spine (53 pyogenic osteomyelitis and 5 iatrogenic and primary discitis) were admitted and treated at our department. Clinical analysis was carried out following results were obtained. 1. The incidence was higher in the 3rd and 4th decade and the sex ratio between male and female was 2.1:1 2. The relative frequency of the commonly involved sity were lumbar(60), thoracic(17.), cervical(9%), lumbosacral(7%), thoracolumbar(3.5%), cervicothoracic(1.5%), in that orders. 3. The morbidity period less than 1 month was only in 22% and that less than 1 year was only 4. The frequent clinical symptoms and signs were back pain(91), tenderness(88%), muscle spasm (76%), and fever and chillness(41%). 5. The causative microorganism was identified in 43 cases among which 77% was coagulase positive staphylococcus. 6. Expected spontaneous bony fusion was not found in any case of 9 follow-up cases of conservatively treated group, while excellent bony union was noticed in all 16 follow-up cases of anterior fusion group except one. 7. Anterior spinal fusion seems be to indicated in those cases such as with failure of conservative treatment, paraplegia, concomitant mechanical instability, long duration of sinus tract and even with dubious bacteriological diagnosis. 8. Anterior spinal fusion for pyogenic osteomyelitis and discitis has the advantages, that is eradication of diseased foci with easier bacteriological diagnosis, cord decpmpression, increase of bony stability, and promotion of bony union. 9. Laminectomy was indicated in those cases with epidural abscess. 10. Bone scan and computed tomography were useful in the early diagnosis and evaluation of treatment results.

BACKGROUND: The immunohistochemical detection of endothelial differentiation in skin tumors has been hindered by the relative paucity of reliable markers that are applicable to rou- tinely-processed specimens, which are both specific and sensitive as well. OBJECTIVE: This study was designed to evaluate the utility of CD31 and CD34, newly introduced vascular markers, in the immunohistochemical differentiation of vascular neoplasms from other mesenchymal tumors and to compare their sensitivity and specificity with factor VII-related antigen (FVIIIRA). METHODS: Paraffin-embedded specimens of 26 cases of benign and malignant vascular tumors and 25 cases of non-vascular mesenchymal neoplasms of the skin and subcutis were investigated for CD31, CD34, and FVIIIRA expression using immunohistochemical methods. RESULTS: CD31-immunoreactivity was observed in all of the 26 vascular lesions. CD34 and FVlllRA were labelled in 23 cases and 16 cases of vascular tumors, respectively. All of the 25 non-vascular mesenchymal tumors were negative for CD31 and FVIIIRA. In contrast, positive reactivity for CD34 was seen in 14 cases, among which dermatofibrosarcoma protuberans(2/2), neurofibroma(8/8), neuriilemmoma(2/2), and leiomyoma(2/3) were included. CONCLUSION: Our results indicate that CD31 is a more sensitive and specific vascular marker than CD34 and FVIIIRA. A small panel composed of these three antibodies will constitute a comprehensive and reliable method for identifying tumors of vascular origin.

OBJECTIVE: The aims of this study were to analyze the natural history of patients with pseudomyxoma peritonei originated from mucinous ovarian tumor, evaluate clinical and pathologic variables, and review our experience with available therapeutic modalities. METHODS: Six patients were treated for pseudomyxoma peritonei originating from mucinous ovarian tumor at Severance Hospital between 1990 and 1998. The data were collected retrospectively and all charts were reviewed RESULTS: The mean age at diagnosis was 51 years, and most common symptoms were abdominal distension. Pseudomyxoma peritonei was found in association with five mucinous ovarian tumors of borderline malignancy, and one ovarian mucinous adenoma. All patients underwent surgical staging and cytoreduction, three patients received postoperative adjuvant chemotherapy and, of these, two developed recurrence. With respect to survival, all patients were alive, four were alive and free of disease, two were alive with disease at the end point of study. CONCLUSION: Pseudomyxoma peritonei is commonly associated with borderline mucinous ovarian tumors, and is a frequently relapsing and protracted disease. But aggressive and repeated debulking surgery is recommended for long survival.

Nesidioblastosis, also known as persistent hyperinsulinemic hypoglycemia of infancy(PHHI) or familial hyperinsulinsm, is the most common cause of recurrent severe hypoglycemia in infancy. It is an autosomal recessive disorder characterized by irregular insulin secretion leading to inappropriately raised plasma insulin concentration compared to blood glucose levels. Recently, mutations in the sulfonylurea receptor(SUR) have been described in association with PHHI. The mainstay of medical treatment is glucose infusion and diazoxide or long acting somatostatin. If medical treatment fails in preventing hypoglycemia, near total pancreatectomy is recommended. We report one case of nesidioblastosis cured by near total pancreatectomy with brief review of literatures.

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.
