Transient synovitis of the hip in children is a non-specific inflammatory and self-limited condition. It is also the most common cause of painful hip in children under ten years of age. Despite of the benign prognosis, there are many difficulties in distinguishing it from other diseases of the hip joint. It remains a common diagnostic problem for clinician because the clinical symptoms, physical findings, and conventional radiography is not pathognomonic of the condition. The authors paid attention to the increase of effusion in the affected hip and studied the value of the hip ultrasonography in 24 cases of transient synovitis from August 1985 to July 1987. The results are summerized as follows : 1. The ratio of male to female was 7 to 1, average age was 7.9 yrs, average hospitalization period was 4.5 days. 2. In simple X-ray studies, no bony change was detectable except for soft tissue signs in 68% of the cases. 3. Capsule-to-bone distance in sagittal ultrasonographic section revealed abnormal increase in 87.5% of the affected hip. 4. Average capsule-to-bone distance of affected hip joint was 7.50 mm, while that of the normal hip was 4.26 mm. 5. As shown in the above studies, ultrasonography can be considered good noninvasive technique in detection and follow-up of hip effusion. So, it is thought to be a valuable method in the diagnosis of transient synovitis of the hip in children.

PURPOSE: Choroid Plexus papilloma is a rare intracranial neoplasm that is most commonly found in the trigone of the lateral ventricle in children or in the fourth ventricle in adult. Extraventricular extension of choroid plexus papilloma has been rarely reported within the cerebellopontine angle (CPA) cistern. Authors report two cases of choroid plexus papilloma in the posterior fossa seen on magnetic resonance imaging (MRI). MATERIALS AND METHODS: MRI findings of two cases of choroid plexus papilloma in posterior fossa were retrospectively reviewed. RESULTS: In the first case, the tumor was in the fourth ventricle and extended to the left CPA cistern via the foramen of Luschka. In the second case, the tumor presented as an expansile mass of the of fourth ventricle and right lateral recess. Multiple signal voids of low intensity due to prominent feeding vessels and calcifications within the tumors were noted. CONCLUSION: This report demonstrates MR findings of choroid plexus papilloma in the posterior fossa with the brief review of the literatures.

As an attempt to evaluate any possible effects of dimethylsulfoxide (DMSO) on the phenomena of membrane transport, effects on the short-circuit current (SCC) and potential difference (PD) across the isolated frog skin were studied under the conditions of various bathing medium, Changes of SCC and PD were measured by the method described by Ussing and Zerahn. Addition of DMSO to the inside bathing medium resulted in an initial increase in SCC followed by a secondary decline to pre-DMSO level, while DMSO at outside medium was without effect. Dose-responses(SCC) relationship revealed a linear one from 30 to 60 mM. Substitution of chloride by sulfate ion from bathing medium caused no alteration in the basic pattern and magnitude of response, thus indicating the specificity of DMSO action on the Na transport. Hypertonic solutions of DMSO added to either outer or inner bathing medium evoked a prompt fall in SCC and PD consistently. By isotopic measurement of sodium fluxes with Na24, it was evident that increased sodium influx was entirely responsible for the initial increase in SCC induced by DMSO. Of various parameters concerned with transepithelial Na transport, outer membrane permeability to Na (PoNa) was shown to be the onIy parameter which was significantly elevated by DMSO administration. From these findings, it was postulated that DMSO-induced increment in sodium influx was mediated by its stimulating action on the sodium penctration through the outer permeability barricr after binding to a receptor site different from that for the antidiuretic hormone (ADH.)

The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n=16, 100%), hyperattenuation of MCA (n=3), obscuration of lentiform nucleus (n=6), loss of insular ribbon (n=6) and subtle low density in hemisphere (n=5). The most frequent findings was effacement of cortical sulci in our study, and it was though to be the most important sign of early acute cerebral infarction.

BACKGROUND: Vascular dementia is common cause of dementia, second to the dementia of Alzheimer desease. However in Asia and many developing countries, the incidence of vascular dementia exceeds that of Alzheimer's disease. Though many stroke-related factors related the nature of vascular injury, e.g. infarction and hemorrhage, have not assessed yet. Clarifying the difference of electroencephalograpy and clinical prognosis between infarction and hemorrhage, the aim of this study was to elucidate the role of nature of vascular injury. METHODS: to reduce confounding factors, the study population was restricted to the patients of single hemispheric striatocapsular infarction and hemorrhage saving cortex. On admission, we checked the KMMSE and FIM scores and using quantified EEG, we analyzed occipital peak frequency and the relative background alpha, theta and delta spectra power taken from 16 derivations by averaging twenty-2 -sec epoch in infarction, hemorrhage patients and elderly controls. After 6 months follow up, we compare the MMSE, FIM score between infarction and hemorrhage group. RESULTS: 1) Compared with infarction group, hemorrhage groups had a significantly bilateral lower occipital peak freqauency and background bilateral alpha spectra power. 2) In hemorrhage group, there is lower tendency in K-MMSE after 6 month follow up compared to infarction group. CONCLUSION: This study suggests that hemorrhage show more bilateral electrophysiological dysfunction than infarction group and possible grave prognosis for vascular dementia compared to infarction group.

In Korea, slipped capital femoral epiphysis is a rare disease. In which the capital femoral epiphysis migrate posteriorly and inferiorly against the neck portion. Sometimes it should be differentiated from other conditions that separate the femoral capital epiphysis. We have experienced a rare case of separation of capital femoral epiphysis due to an osteosarcoma in the proximal femoral metaphysis in the 15 years of old girl.

Arthrodesis of the knes has lost its nopularity since the development of modern knee replscement arthroplasties, however it still has its place as a salvage procedure when replacement arthroplasties are contraindicated. Various techniques have been in the use including the time-tested Charnleys compressiori arthrodesis. Instead of using Charnley's and other similar compression devices, the authors applied single or double compression plates in 8 knees with severe destruction and deformities, and the results are summerized ss follows: l. Included in this series are 5 cases of tuberculous arthritis, 1 case of septic arthritis, 1 case of resistant scar contracture, and 1 case of Charcots knee. 2. Successful fusion was obtained within 18th week, aversge 13th week. No case of pseudarthrosis was experienced. 3. 3 cases of postop. wound drainage and 1 case of peroneal nerve palsy were experienced, but these did not compromise the final results. 4. It may be concluded that Arthrodesis of the knee using compression plate is rigid enough to permit early mobilization of patients and get the certainty of union.

Closed intramedullary nailing for trochanteric fractures of femur has many advantages such as minimal operative trauma, low incidence of infection, good stability of fracture, low incidence of delayed or nounion and early ambulation. Complications have been frequently experienced especially in elderly, osteoporotic patients, but these could be avoided by meticulous surgical procedure. The authors hsve treated 99 cases of intertrochanteric fracture and 23 cases of subtrochanteric fracture from March 1982 to December 1987 with this method and the results are summerized as follows : 1. The aversge age was 61.4 yrs. 2. In classification of intertrochanteric fracture, stable fractures(Kyle type I & II) were 53 cases(43.3%) and unstable fractures(Kyle type III & IV) were 46 cases(37.6%). And in subtrochanteric fracture, stable transverse fractures were 12 cases(9.8%) and unstable long oblique or spiral fractures were 11 cases(9.0%). 3. Intraoperative complications were experienced in 23 cases(18.8%). The entry hole breakage was most common and occurred in 16 cases. 4. Of the 94 patients with more than 6 months follow-up, 21 patients(22.3%) showed more than one complication, e.g, knee joint pain in 15 cases, external rotation deformity in 8 and nail migration in 11 including 3 cases of fixation loss and one case of nonunion with nail breakage, etc. 5. Complications occurred more frequently in unstable fractures(31.8%) and in old ages (29.1%) than in stable fractures and in young ages respectively. And it was felt that complications could be minimized by packing of the medullary canal with nails. 6. It is thought that flexible intramedullary nailing is a good method for trochanteric fractures of femur not only in elderly debilitated patients but also in young patients. However, experience and caution are required to prevent complications.
