Recently, there were many cases which was associated with bone defect in the limb and skin defect. We had performed vascularized osteocutaneous fibular transfer with microsurgical technique and experienced early bone union and simutsneous external wound healing. So we, authers, reviewed 12 cases of vascularized osteocutaneous fibular transfer which were performed to the extensive bone defect of the tibia and associated soft tissue injury. And the following remarkable results were obtained. 1. With the uncontrolled bone infection, the vascularized osteocutaneous fibular transfer was able to be performed and there was no non-union. 2. During the follow up period, the grafted fibula had been hypertrophied. 3. In the cases which the fibula were grafted to the defect after the segmental and partial excision of the tibia, in general, the partial weight bearing was able to be started from 3 months to 5 months after the operation, In the cases with segmental and complete excision of the tibia, the partial weight bearing was able to be started from 5 months to 7 month after the operation. 4. In adult, free fibula can be obtained and grafted as 20cm as long and the fibula was a good donor for extensive long bone defect as a compact bone; the skin flap with fibula can be obtained and grafted as 17 × 9cm as large in our experience. 5. In the vascularized osteocutaneous fibula transfer, the skin flap could be confirmed wheather the vascular anastomosis is patent or not as a monitor.

The weightlifting is a sort of the sport, which has objects to promote the physical condition and to develop the fundamental strength in the adolescent period, but thete been no interests from the view points of sports injuries for weightlifting. So the authors have studied the changes in the lumbosacral region and wrist of the adolescent weightlifters and the results obtained are as follows; 1. The increase in the lumbosacral angle has a statistically significant relationship with the low back pain in the adolescent weightlifters. 2. The ulnar variance shows statistically significant increase than the control group and its increase seems to be a causative factor in developing wrist pain among the adolescent weightlifters.

Sinking skin flap syndrome is defined by a series of neurological symptoms with skin depression at the site of cranial defect. We experienced neurological improvement in a patient with markedly sunken craniectomy site after ventriculoperitoneal shunt (V-P shunt) clamping operation. A 17-year old female patient was in vegetative state and spastic quadriplegia after traumatic brain injury. She was suffered from frequent vomiting. To evaluate central nervous system problem we checked brain computed tomography which showed that right frontotemporoparietal craniectomy area was markedly sunken and midline was shifting to the left. After V-P shunt clamping operation, craniectomy site was elevated and midline shifting was improved. Vomiting was disappeared. Coma Recovery Scale-revised (CRS-R) score was improved from 3 to 6.

The incidence of metastasis to the spinal cord in patients with systemic carcinoma has been extimated to be 0.9 to 8.5%. Attempts to aggressively remove intramedullary spinal cord tumor may cause increased neurologic deficits and a worsend outcome. The authors present the case of a multiple intramedullary meetastatic spinal cord tumor which had metastasized from the lung to the thoracic spinal level. Pathologic diagnosis of the small cell carcinoma was made from the tumor specimen obtained by stereotaxic-guided neddle biopsy after which the patient was treated with radiotherapy and chemotherapy.

OBJECTIVE: Radiation injury includes radiation necrosis and apoptosis. The purpose of this study is whether steroids and calcium channel blockers are effective for the prevention of single high dose irradiation-induced apoptosis in the rat brain. METHODS: Eighty Sprague-Dawley rats were divided into four experimental groups: Control(nontreated, n=20), Dexamethasone-treated(0.1mg/kg, n=20), Prednisolone-treated(2mg/kg, n=20), Nimodipine-treated (0.5mg/kg, n=20). After drug was administered, the right hemisphere of rat's brain was exposed to a single 10Gy dose of gamma rays using Ir-192. All brains underwent histological examination at 1 week, 2 weeks, 4 weeks, and 8 weeks after irradiation to evaluate cortical thickness and number of apoptotic cells. Apoptotic cells were detected by TUNEL assay. RESULTS: In nimodipine-treated group, apoptotic cell count was reduced significantly, compared to that of control(non treated) group at 4 and 8 weeks after irradiation(p<0.05). The decrease of cortical thickness was reduced significantly in nimodipine-treated group, compared to that of control group(p<0.05). There was no significant changes in the number of apoptotic cells and cortical thickness in prednisolone and dexamethasone-treated groups compared with those of control. CONCLUSION: These results suggest that nimodipine treatment may have effects on the prevention of radiation-induced apoptosis. If it could be established that calcium channel blockers inhibit radiation injury, they might be useful in radiation therapy. Further investigation of calcium channel blockers including dosage effectiveness, intracellular calcium ion concentration and effects on tumor tissue are necessary to clarify the usefulness of nimodipine.

Increasing vigorous chemotherapy for cancers including primary and matastatic tumors has resulted in prolonged survival. However, there has been an associated increase in neurotoxicity as a result of it. All classes of chemotherapeutic agents contain drugs that are potentially neurotoxic. The authors has studied three cases of leukoencephalopthies developed during adjunctive therapy with 5-flurouracil and cisplatin for adenocarcinoma of the stomach. None of the patients had evidence of metastasis or any previous neurologic diseases. The duration of chemotherapy before onset of neurological symptoms ranged from 8 to 12 weeks. Two of the 3 patients presented progressive decline in mental status and ataxia after 2~3 weeks, while the third one had two unexplained episodes of loss of consciousness. In all of these patients, magnetic resonance imagings demonstrated prominent periventricular white matter lesions. Cerebral biopsies were performed stereotaxically in 2 patients. The morphological features were active demyelinating disease and edema. All three patients had improved after the cessation of chemotherapy and a short course of corticosteroid therapy, suggesting that these alarming events such as nausea, vomiting dizziness, dysarthria, and mental change were a toxic reversible side effects from these chemotherapeutic agents. This syndrome may represent the pathological basis for 5-fluorouracil neurotoxicity, however we cannot completely exclude the role of cisplatin in the occurences of the above syndromes.

Authors report the first autopsy case of acquired immune deficiency syndrome in Korea. The patient was a 26 years old Korean male who died of respiratory failure due to mixed pulmonary infections. He had history of homosexual contacts with partners of both domestic and foreign nationalities. Initial presentation was unexplained fever for two months. Serological test and western blot test for anti-HIV were positive and T-cell subset analysis revealed T3/T4/T8 to be 73/8/67%. Pulmonary tuberculosis with mediastinal lymphadenopathy and esophagonadal fistula and oral candidiasis were presented. Respiratory infection progressed gradually and he died seven months after the initial symptom. Autopsy findings were generalized severe lymphoid cell depletion, especially of T-cell population and mixed pulmonary infections with Pneumocystis carinii and cytomegalovirus (CMV). The CMV infection involved lungs and adrenals. Oral candidiasis was also demonstrated.

The authors present a statistical survey of the general incidence, age distribution, and preferential site of 631 tumors of the brain which have been surgically treated at Korea university medical center, department of neurosurgery over the last period of 10 years from 1985 to 1994. Among them 269 cases were males and 362 were females. Of the 631 intracranial neoplasms verified histologically, tumors of neuroepithelial tissue comprised 34%(212 cases), tumors of meninges 23%(148 cases), pituitary adenoma 18%(114 cases), metastatic tumors 8%(50 cases), neurilemmomas 8%(49 cases), germ cell tumors 3%(13 cases), cyst and tumor like lesions 3%(16 cases), and lymphomas 1%(5 cases). Of the 178 gliomas, astrocytic tumors comprised 83%(148 cases), oligodendroglial tumors 11%(20 cases), ependymal tumors 3%(6 cases) and mixed gliomas 1.7%(3 cases). Brain tumors occurred most frequently in the age group of 45-50 years, as seen by an incidence of 63 cases(10%). The male to female ratio was 0.74: 1. Tumors that showed a definitive preponderance of females over males were meningiomas, neurilemmomas, and pituitary adenomas. Supratentoral and infratenorial cases were 73%(461 cases) and 26%(162 cases), respectively and the remaining cases involved both sites. Of the 114 cases of childhood and adolescent tumors, 60 were male and 54 were female. Supratentorial tumors were 56% and infratentorial were 44%. The tumors in order of frequency were astrocytomas(28%), primitive neuroectodermal tumors(21%), craniopharyngioma(10%) and so on. Meningiomas occurred most frequently in parasagittal/falx area(25%), followed by cerebral convexity 23%, sphenoid 14%, posterior fossa 13%. Among pituitary adenomas, prolactinomas(32%) were the most common and followed by null cell adenomas 31%, growth hormone cell adenomas 15%, mixed GH-PRL cell adenomas 11%.
