BACKGROUND: Histological analysis of tuberculosis shows a spectrum of findings, from well formed granulmatous inflammation with few bacilli in patient with normal immune response to M. tuberculosis to poorly formed granulomatous inflammation with many bacilli in patient with defective immune response. To evaluate the degree of immune response to M. tuberculosis, we studied the histologic features, including the presence of acid fast bacilli(AFB) in lymph node of patients with cervical tuberculous lymphadenitis, and compared them with clinical characteristics. METHODS: We reviewed the histologic features of 33 cases of cervical tuberculous lymphadenitis and processed the excised nodes for auramine-rhodamine staining to detect AFB. The AFB positivity in tissue was compared with the histologic features(degree of granuloma formation, presence of caseation necrosis, presence of neutrophilic infiltration) and clinical characteristics (lymph node size, duration of symptom, presence of local symptom or radiologic evidence of pulmonary tuberculosis). RESULTS: 1) The mean age at diagnosis was 42.4 years, and male to female ratio was 1 : 45. 2) Histologically, all cases showed well formed granuloma and variable degrees of caseation necrosis, and 39% of the cases showed neutrophilic infiltration in the granulomatous inflammation. 3) AFB were confirmed in 52% of the cases, and they were found extracellularly and at the periphery of caseation necrosis. 4) There was no association between AFB Positivity and histological features or clinical characteristics. CONCLUSION: Cervical tuberculous lymphadenitis showed well formed granulomatous inflammation with caseation necrosis, and there was no association between AFB positivity in the tissue and histological or clinical characteristics.

Osteogenic sarcoma arise from primitive bone forming mesenchyme which is transformed into neoplastic osteoid and bone. Most osteogenic sarcomas originate in long bone, only rarely do they occur as primary tumor of the spine. A case is presented in which a patient who had suffered from paraplegia and self voiding difficulty. It was diagnosed as osteogenic sarcoma of the 5th thoracic spine which was operated and confirmed by microscopically, and is discussed with a brief review of the literatures.

Clinical observation and analysis were performed on 481 cases of craniocerebral injuries under 15 years of age those were treated at Chung-ang University hospital during the period from January, 1972 to August, 1975. Following results were obtained: 1. There were 302 males and 179 females and sex ratio was 1.7:1. 2. Age incidence of the accidents was greatest at 5 years of age and mostly distributed to the age group between 5 to 7. 3. Seasonal peak of the accidents was at June. 4. The most frequent cause of the craniocerebral injuries was traffic accident(277 cases, 57.59%), and the next was fall from height(159 cases, 33.06%). 5. No deterioration of consciousness before and after the admission was observed in 176 cases(3.6%). 6. Pupillary change was observed in 28 cases in which unilateral were 21 and bilateral were 7. Babinski sign was elicitable in 91 cases. 7. Early convulsion and vomiting were frequent symptoms in childhood. 8. Skull fracture was observed in 204 cases(40.33%) in which linear fracture was most frequent. The location of the linear fracture was parietal and the predilection sites of the depressed fractures were frontal and parietal. 9. The accompanying rate of skull fracture in intracranial hemorrhage was;epidural 75%, subdural 50% and subarachnoid 17.3%. 10. The overall mortality was 8.32%. In non-surgical group(442 cases), the mortality rate was 7.47% but in surgical group(39 cases), operation mortality was 17.95%.

Hemichorea-hemiballsim has been reported as a rare Implication of nonketotic hyperglycemia. Recently, Some reports revealed that brain magnetic resonance images of nonketotic hyperglycemic patients with hemichorea-hemiballism showed characteristic contralateral striatal signal abnormality, We present six patients with hemichorea-heniiballism. All of them had diabetes mellitus and performed brain MR images. The MR images of them showed high signal intensity on Tl-weighted images and low signal intensity on T2 weighted images in the striatum contralateal to the involuntary movement. In general, the striatal high signal intensity on TI weighted images are presumed to have developed following hemorrhagic transformation, osmotic myelinolysis, or mild ischemia with reversible deposition of calcium or other material occurred in association with nonketotic hyperglycemia. However the precise mechanism of this signal change is not clear yet and needs pathological confirmation.

We report a case of chronic encapsulated intracerebellar hematoma occurring during infancy. An 18 month-old boy was admitted because for 3 months, his head could not be held upright, but fell to the left. Computed tomographic(CT) scanning and magnetic resonance imaging(MRI) of the brain revealed a round mass at the cerebellar vermis ; the lesion simulated a cerebellar tumor such as a medulloblastoma. The mass was surgically removed and found to be a well-encapsulated organized intracerebral hematoma. The characteristic clinical and radiologic findings and histopathologic features are discussed, and a survey of the literature is included.

The incidence of paraplegia following drain of cerebrospinal fluid(CSF) by lumbar puncure below a spinal block is rare, and most of them occurred in spinal tumor. We report a case of acute paraplegia following lumbar puncture for computed tomography myelography(CTM) in a 42-year-old man who sustained a cervical disc herniation. Four hours after lumbar puncture for CTM, sudden paraplegia was developed. After emergent anterior cervical discectomy and fusion with cervical plating, the patient recovered completely. To the authors' knowledge, this is the first case of spinal shock complicating lumbar puncture for routine myelography in a patient with cervical disc herniation. The prompt recognition of this unusual complication of lumbar puncture may lead to good clinical outcome. Instead of CTM requiring lumbar puncture, MRI should be considered as the initial diagnostic procedure in a patient of cervical disc herniation associated with myelopathy. We discuss the possible mechanisms of acute paraplegia following lumbar puncture with literature review.

During the five years from 1972 to 1976, 2308 cases of head injury were admitted to Han Kang Sung Shim Hospital and were treated in the department of neurosurgery. Of these, 1547 were adults aged 16 and over, and 761 were infants and children up to the age of 15. The results of clinical analysis of 761 cases of above series have been reported early in 1977. In this paper, a clinical analysis of 1547 adult cases of above series was performed and following results were obrained. 1) There were 1077 males and 470 females, and the proportion of male was much greater than female, male-female ratio was 2.3:1. 2) The age incidence was greater in the age group between 16 to 40, becoming maximal at the second decade. 3) Traffic accidents form by far the largest group (62%), and next are, in order of incidence, accidents due to blow or assault, fall from a height, simple fall, and industrial accidents. 4) Among the 1547 patients investigated, 20 of 1275 cases those conscious or confused on admission were died and 103 of 272 those semicomatose or comatose were died. 5) Skull fractures were seen in 504 cases, and nearly half of those, 242 or 48%, were linear fractures. 6) Of the 333 patients with intracranial hemorrhage or subdural hygroma, 181 were accompanied by skull fracture and epidural hematoma showed highest incidence, 80.46%. 7) Of 87 epidural hematoma, 69(79%) were found in the temporal and parietal fossae of the skulls, and of 70 subdural hematoma, 60(85.7%) were found in the parietal and temporal surface of brains. 8) Operation were carried out in 228 patients and surgical mortality was 24.5%, and subdural hematoma showed highest mortality, 40.0%. 9) Among the 228 surgical cases mortalities were 30% in those operation have been carried out within 6 hours of injury, 24% in those within hours 6 to 24, and 14% in those after 24 hours. The earlier the surgery had to be carried out, the higher operation mortality was noted. 10) The overall mortality in this series was 7.95%.

OBJECTIVES: The purpose of this study was to compare the efficacy between switching patients with Alzheimer's disease (AD) from galantamine or rivastigmine to donepezil because they were not responding adequately, and naive patients with AD who initiated therapy with donepezil. METHODS: A total of 108 patients were recruited for this 52-week study. The effect of donepezil on cognitive function was measured using Alzheimer's Disease Assessment Scale-cognitive subscale-preliminary Korean version (ADAS-cog-K). Patients' activities of daily living using Seoul-Activities of Daily Living (S-ADL) and the Seoul-Instrumental Activities of Daily Living (S-IADL);behavioral symptoms using the Korean version Neuropsychiatric Inventory (K-NPI) were measured at baseline, 13-weeks, 26-weeks, 39-weeks and 52-weeks. We defined the responsive patients to donepezil at those who showed a cognitive improvement or no change during the first six-month clinical trial. RESULTS: 86 naive patients and 22 switching patients were enrolled in the study. 74 patients completed the study and 34 discontinued their treatment before week 52. There was no significant difference between two patient groups in demographic data, baseline characteristics and dementia severity except duration of illness. The total ADAS-cog-K scores were not significantly different from baseline after 52 weeks of treatment in both groups. Both groups demonstrated deterioration of S-ADL and S-IADL at 52 weeks. The NPI scores did not significantly change in both groups. Based on the operational criteria, 61.6% of the naive group and 54.5% of the switching group were responders to donepezil. CONCLUSION: The switching group had similar levels of efficacy with the naive group who initiated therapy with donepezil. These results suggest that patients not responding adequately to rivastigmine or galantamine may improve or stabilize after switching to donepezil and prior medication does not effect donepezil's efficacy.

OBJECTIVES: The purpose of this study was to compare the efficacy of galantamine treatment, especially attention ability between patients with pure Alzheimer's disease (AD) and Mixed dementia (MD) during a 24-week trial. METHODS: A total of 40 patients were recruited for this 24-week study. The effect of galantamine on attention was measured using Seoul Computerized NeuroCognitive Function Test (SCNT) and frontal functions test of Seoul Neuropsychological Screening Battery (SNSB). Patients'activities of daily living using the Seoul-Activities of Daily Living (S-ADL) and the Seoul-Instrumental Activities of Daily Living (S-IADL) ; behavioral symptoms using the Korean version Neuropsychiatric Inventory (K-NPI) were measured at baseline and 24-week. RESULTS: 17 pure AD patients and 23 MD patients were analyzed in this study. Attention as measured by SCNT was not significantly different from baseline after 24 weeks of treatment in both groups. There was no significant difference between two groups in mean change from baseline in the SCNT, S-ADL, S-IADL and K-NPI scores at 24-week. CONCLUSION: Galantamine showed a therapeutic effect on cognition, activities of daily living, neuropsychiatric symptoms in pure AD and MD. Furthermore, Galantamine may specifically help to maintain attention and it may have positive effects on other cognitive and functional abilities.

OBJECTIVES: The purpose of this study was to compare the efficacy of donepezil treatment between patients with pure Alzheimer's disease (AD) and Mixed dementia (MD) during a 12-month trial. METHODS: A total of 139 patients were recruited for this 52-week study. The effect of donepezil on cognitive function was measured using Alzheimer's Disease Assessment Scale-cognitive subscale-preliminary Korean version (ADAS-cog-K). Patients' activities of daily living using the Seoul-Instrumental Activities of Daily Living (S-IADL) and Seoul-Activities of Daily Living (S-ADL);behavioral symptoms using the Korean version Neuropsychiatric Inventory (K-NPI) were measured at baseline, 13-weeks, 26-weeks, 39-weeks and 52-weeks. We defined the responsive patients to donepezil at those who showed a cognitive improvement or no change during the first six-month clinical trial. RESULTS: 84 pure AD patients and 34 MD patients were available for intent-to-treat (ITT) last observation carried forward (LOCF) analysis. There was no significant difference between two groups in mean change from baseline in the total ADAS-cog-k, S-ADL, S-IADL and K-NPI scores at 52-week. Based on the operational criteria, 60.7% of pure AD patients and 58.8% of MD patients were responders to donepezil. CONCLUSION: MD patients had similar levels of efficacy with pure AD patients and donepezil was well tolerated in both groups. These results suggest that donepezil is an effective and well-tolerated treatment for MD patients as well as for pure AD patients.
