The elbow joint is the most commonly dislocated-joint in the body except for the shoulder, and in children less then 10 years old, it is the most frequently dislocated articulation. The injury and the treatment are well described in most standard textbooks, but the characteristic findings and follow-up evaluations are not generally recognized. Authors have clinically analyzed 45 cases of traumatic fracture and dislocation of the elbow joint which are treated between January, 1975 and June, 1985 at the Department of Orthopedic Surgery, Wonju Medical College of Yonsei University. The results were as follows; 1. The age incidences were in even distribution except in the old ages where the incidence was low and the male to female ratio was 7: 3. 2. The major cause of the injury of the elbow was fall down (60%). 3. Posterior and posterolateral dislocations were about 60% of all cases. 4. Associated fractures were 35.6% of all the elbow dislocations, of which medial epicondyle fracture had the highest incidence. 5. Complications including ulnar nerve injury (3 cases), median nerve injury(1 case), radial nerve mjury(1 case), rupture of brachial artery(2 cases), recurrent dislocation(1 case) and calcification of ligament(2 cases) were observed. 6. Pure elbow dislocation occurred in 13 cases (28.9%). 7. The average immobilization period for patient with non-operative treatment (45%) and operative treatment(55%) were 7 days and 3 weeks, respectively, and much better results were seen in patients with non-operative treatment than in operative treatment and in shortened immobilization period.

A case of severe osteoarthritic patient of both hip treated with McKee-Farrar total endoprosthesis on one hip is reported. The introduction, indication, procedure of the surgery and the use of the self curing acrylic cement were reviewed briefly. The hip following the surgery, even though the follow-up duration is short, showed exceIlent result.

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.

OBJECTIVES: Auditory verbal hallucination (AVH) is knoun for its high prevalence and difficulty in evaluation. Authors hypothesized that it may be possible to find useful dimensions of AVH that reflect the clinical status of schizophrenic patients by assessing the multi-dimensional changes and linguistic forms' of AVH during antipsychotic treatment. METHODS: 33 schizophrenic patients with AVH were selected and periodically assessed with the 11 items of hallucinations subscale of 'The Psychotic Symptom Rating Scales (PSYRATS)'. In addition, to assess the linguistic forms observed in the AVH, the evaluations of sentence structure of AVH reported by the patients were conducted. RESULTS: PSYRATS showed the multidimensionality inherent in AVH. The changes in the quantitative dimensions did not correlate well with patients' subjective distress. However, qualitative changes in the cognitive and emotional dimensions showed more favorable correlation with clinical course of the patient. The sentence structures of AVH showed tendency to change from "sentence" to "non-sentence" type with overall improvement during treatment. CONCLUSION: Multi-dimensional approach to AVH can give us more information about the changing patterns of multi-faceted structure of AVH and clinical status of patients than one-dimensional or categorical approach.

Zonisamide was administered to 20 patients with refractory epileptic seizures. The mean duration of the administration was 6 months, and the mean dosage was 7.2 mg/kg/day. The efficacy of zonisamide was rated remarkable in 15% of the cases, improvement in 40%, and no change in 45%. The response rates of zonisamide were 62.5% for myoclonic seizures, 50% for tonic-clonic seizures, 80% for atonic seizures and 33.3% for atypical absence seizures. There was no correlation between the clinical response and dose or serum concentration of the drug. The adverse effects were observed in 35% of the cases which were drowsiness, dizziness, ataxia, nausea, and vomiting. In all cases, however, the administration of zonisamide could be continued.

9.Pulmonary Lymphangioleiomyomatosis: A case report.

Lymphangioleiomyomatosis(LAM) is a rare disease of women of child-bearing age in which there is progressive hyperplasia of atypical smooth mucle along lymphatics in the lung, and/or axial lymphatics in the thorax and abdomen, resulting in honeycombing of lung. Interestingly there has been a speculation that it represents a forme furste or incomplete expression of tuberous sclerosis complex. This is based on the observation that patients with tuberous sclerosis can manifest pulmonary lesions indistinguishable from LAM. We report a case of LAM occuring in a 39-year-old female, who complained of recurrent pneumothorax, chest pain and shortness of breath. Three years ago, the patient had right nephrectomy under the diagnosis of ruptured angiomyolipoma. A X-ray film of the chest showed honeycombing with a diffusely reticulonodular pattern and cyst-like spaces. She had a characteristic facial appearance of adenoma sebaceum, which her father and uncle had. Microscopically, the lung showed a marked smooth muscle proliferation around the slit-like lymphatic spaces and also some respiratory bronchioles.

PURPOSE: Bilateral high signal intensity in basal ganglia on Tl-weighted images is unusual. the purpose of this study is to describe the pattern of high signal intensity and underlying disease. METHODS AND MATERIALS: During the last three years, 8 patients showed bilateral high signal intensity in basal ganglia on Tl-weighted image, as compared with cerebral white matter. Authors analized the images and underlying causes retrospectively. Of 8 patients, 5 were male and 3 were female. The age ranged from 15 days to 79 years. All patient were examined by a 0.5T superconductive MRI. Images were obtained by spin echo multislice technique. RESULTS: Underlying causes were 4 cases of hepatopathy, 2 cases of calcium metabolism disorder, and one case each of neurofibromatosis and hypoxic brain injury. These process were bilateral in all cases and usually symmetric. In all cases the hyperintense areas were generally homogenous without mass effect or edema, although somewhat nodular appearence was seen in neurofibromatosis. Lesions were located in the globus pallidus and internal capsule in hepatopathy and neurofibromatosis, head of the caudate nucleus in disorder of calcum metabolism, and the globus pallidus in hypoxic brain injury. CONCLUSION: Although this study is limited by its patient population, bilateral hyperintense basal ganglia is associated with various disease entities. On analysis of hyperintense basal ganglia lesion, the knowledge of clinical information improved diagnostic accuracy.
