The management of pineal region tumor remains controversial. This paper reports a case of pineocytoma which was attempted to improve treatment planning by the use of clinical features, computerized tomography, and markers for germ-cell tumor. A presumptive diagnosis could be made and this tumor less likely to respond to radiotherapy was subjected to primary surgery.

A 44-year-old female with cervical cord compression signs had myelographic and computerized tomographic evidence of extradural spinal cord compression without any tuberculous bony lesion or cold abscess. At surgery, cervical spinal cord was compressed by extraosseous extradural granulomatous tissue which was histologically proved a very rare localized extradural tuberculous granuloma.

The authors report a case of massive spontaneous intracerebral hematoma in a infant, caused by bleeding from cryptic vascular malformation associated with vitamin K dependant factor deficiency. The bleeding was initiated by vitamin K dependant factor deficiency, then 3 weeks later hematoma was expanded by rebleeding from malformed vessel after PT and PTT had been returned to normal values. The well circumscribed organized old hematoma with fresh expanded bleeding component within a huge rusty colored cystic fluid cavity was recognized in operative field and pathological ground.

During last 10 years we experienced 25 cases of C.N.S. cysticercosis. Now clinical analysis and evaluation of our cases were made and the results are followings; 1. Prevalence in man and women are nearly same and about 70% of cases are distributed between 20-50 years old. 2. According to Nieto's classification, mostly are ventricular (44%) and parenchymal type (36%). 3. Clinical manifestations were IICP (92%), focal neurological deficits (68%), seizure (48%), altered mental status (36%) and others listed on table 7. 4. In ventricular type, IICP and cerebellar dysfunction signs were predominated but seizure and focal neurological deficits were commonly seen in parenchymal type. 5. Subcutaneous cysticercus nodules were palpated in 32% of cases. 6. Positive stool ova was observed in 29% of cases. 7. Radiologic studies revealed as followings: 16% of cases showed abnormal findings on plain film, 84% on angiography, 94% on ventriculography and 100% on computed tomography and myelography. Computed tomography looks like most helpful diagnostic method for C.N.S. cysticercosis, they usually revealed lucent cystic lesion, hydrocephalic findings and contrast enhancement. 8. Suboccipital craniectomy, craniotomy with removal of parenchymal cyst or laminectomy were done according to location and types of lesion. 72% of operated cases revealed good results and mortality was 4% of cases.

Since the first attemt of internal fixation not much more than a century ago, implants have come to play an important role in orthopaedic surgery. Yet little has been reported about complications which may result from implant surgery. During the period of May 1980 to April 1984, 32 cases of fixation failures were treated in the Department of Orthopaedic Surgery, Hallym College, Kang Nam Sacred Heart Hospital and results were obtained as follows: 1. The most common area involved femoral shaft, but the highest rate was distal femur. 2. The most common period of failure was between 2 to 4 months postoperatively. 3. The leading cause of failure was remaining defects at fracture site. 4. The authors recommend accurate reduction of fracture and bone graft, if necessary, adequate immobilization postoperatively and co-coperation of patient to avoid failure of implant.

OBJECTIVE: Carpal tunnel syndrome(CTS) is the most common entrapment neuropathy in the upper extremities. For the surgical treatment of CTS, endoscopic carpal tunnel release(ECTR) has been developed as a minimally invasive method, alternative to the open procedure over the past decade. The authors present clinical experience and surgical outcome of ECTR. METHODS: One hundred cases(34 right, 30 left and 19 bilateral hands) in 81 consecutive patients(mean age: 51.8 years, range: 33-77 years) with electrodiagnostically-proven CTS underwent a single-portal ECTR from January 2001 to December 2002. Preoperative clinical findings and results of electrodiagnostic studies were compared with surgical outcome respectively after 3-month-follow-up period. RESULTS: Among 100 cases 94(94%) were satisfied with complete or significant relief of symptoms and 6(6%) were dissatisfied with partial or no relief of symptoms. Major complications in 2 cases(one with ulnar nerve injury and the other one with ulnar artery laceration), developed in early experience of ECTR and recurrence in 1 case occured. Severity of electrodiagnostic abnormalities were correlated with surgical outcome but there's no statistical significance between them. Severity of clinical findings, age at onset and symptom duration were not correlated with surgical outcome respectively. CONCLUSION: ECTR is effective in relieving symptoms of CTS with a low complication rate after the learning curve period. Thus, ECTR can be the first procedure, alternative to the open surgery as an efficient, minimally invasive surgical technique for CTS.

OBJECTIVE: Allelic losses or loss of heterozygosity (LOH) at many chromosomal loci have been found in the cells of meningiomas. The objective of this study was to evaluate LOH at several loci of different chromosomes (1p32, 17p13, 7q21, 7q31, and 22q13) in different grades of meningiomas. METHODS: Forty surgical specimens were obtained and classified as benign, atypical, and anaplastic meningiomas. After DNA extraction, ten polymorphic microsatellite markers were used to detect LOH. Medical and surgical records, as well as pathologic findings, were reviewed retrospectively. RESULTS: LOH at 1p32 was detected in 24%, 60%, and 60% in benign, atypical, and anaplastic meningiomas, respectively. Whereas LOH at 7q21 was found in only one atypical meningioma. LOH at 7q31 was found in one benign meningioma and one atypical meningioma. LOH at 17p13 was detected in 4%, 40%, and 80% in benign, atypical, and anaplastic meningiomas, respectively. LOH at 22q13 was seen in 48%, 60%, and 60% in benign, atypical, and anaplastic meningiomas, respectively. LOH results at 1p32 and 17p13 showed statistically significant differences between benign and non-benign meningiomas. CONCLUSION: LOH at 1p32 and 17p13 showed a strong correlation with tumor progression. On the other hand, LOH at 7q21 and 7q31 may not contribute to the development of the meningiomas.
