Legg-Calve-Perthes disease is a hip disorder of undetermined etiology, occurring in children and charaterized by necrosis and repair of the proximal femoral epiphysis. Its etiology and treatment continue to command intense interest among orthopaedic surgeons. It is the purpose of this paper to evaluate the result of our experience in the selected patients with Legg-Calve-Parthes disease treated by innominate osteotomy, In this study, six cases of Legg-Calve-Perthes disease treated at Severance Hospital from March 1976 to November 1978 were analysed clinically, and gratifying results were obtained.

Many procedures of quadricepsplasty were reported by Thompson (1944), Judet (1959), van Nes (1962), Nicoll (1963) and Hesketh (1963) in confining the indication of them for the strictly extra-articular origin of their causes. During the period of January 1979 to August 1979, 5 cases of stiff knee joints were surgically treated by means of arthrolysis and quadriceps release. The result were gratifying. The average gain of flexion was 119 degrees, and extension lag was absent except a case which had compression fracture of femoral condyle.

We present a case of transient acantholytic dermatosis which developed on the face of a 19-year-old Korean girl. Asyrnptomatic pinhead to miliary-grain sized brownish papules arranged in a somewhat band-like outbreak along the left side of the nose for about 3 months. Histopathologic findings were similar to Dariers disease. Immunoperoxidase staining showed that IgG was deposited on the intercellular area of keratinocytes around the suprabasal clefts. Skin lesions disappeared spontaneously in 5 weeks after a skin biopsy.

Compensatory hypertrophy of muscle fibers has been known to occur when burden on a skeletal muscle is increased. However, there have not been reports concerning the response of extraocular muscles following a monocular resection and recession of horizontal muscles, which procedure is a common form of strabismus surgery. A large lateral rectus resection and medial rectus recession was performed in each right eye of 28 rats. After the horizontal muscle surgery, both medial and lateral rectus muscles were obtained from both eyes of each rat with an interval of 2 weeks from the initial operation until 8th week after operation. A mid-portion of an extirpated muscles were frozen and prepared for ATPase staining. With a differential preincubation in two buffered solutions, pH 4.6 and pH 10.3 and ATPase staining, muscle fibers were classified into 3 kinds-global singly innervated fiber(GSIF, alkali-stable), global multi-innervated fiber(GMIF, alkali-labile), and orbital surface layer fiber(OSLF). These muscle fibers were measured using micrometer to find out their diameters and compared with the diameter of extraocular muscle fibers of unoperated rats. All kinds of muscle fibers of a resected lateral rectus showed an increase in their diameteris(p<0.05, Wilcoxon rank sum test) but there was no hypertrophy in the recessed medial rectus the yolk muscle of the resected lateral rectus, medial rectus of the fellow eye also showed hypertrophy of GMIF and OSLF. The lateral rectus of the unoperated fellow eye did not reveal muscle fiber hypertrophy. The postoperative hypertrophy of muscle fibers were observed only at the 2nd and 4th postoperative week specimens. the hypertrophied muscles subsequently returned to the baseline fiber diameter.

Primary hyperparathyroidism is a rare endocrine disease in children. It involves bone and joint, urinary tract, gastrointestinal tract and cardiovascular system. The main cause of these involvement is high level of PTH in serum, resulting in hypercalcemia.An 11 years old male patient who had complained of limping gait since last 18 months, showed typical laboratory and radiological findings of primary hyperparathyroidism. At the ultrasonography, computed tomography and radionuclide scanning, a well defined mass(10 X 15mm) was found on the posterior aspect of the right thyroid lobe. The mass was confirmed histologically as adenoma of parathyroid gland. The patient was successfully treated with subtotal parathyroidectomy and temporal administration of calcium and vitamin D.We report this case of primary hyperparathyroidism with brief review of the literatures.

Cystic hygroma is a rare, endothelial lined cystic lesion of lymphatic origin which is encountered most often in children, usually at birth or early in life. The tumor is usually found in the neck and axilla. It is a soft, nontender, semifluctuant freely movable tumor of varying size filled with lymphatic fluid. The mass is sometimes pedunculated and is uaually multilocular, althouh it may be monolocular. The cystic hygroma of the right axilla and the upper arm, in a 4 month-old female infant, is presented with a review of the literature.

OBJECTIVE: Analyses of the 24 items of the Mini-Memory Test (MiMeT) using the item response theory. METHODS: Item difficulty and item discrimination of all items were evaluated with the 2-parametric logistic model in elderly psychiatric patients with memory impairment (n=332, 48.4%) and without (n=354, 51.6%). The BILOG 3 for Windows was employed for the analysis. RESULTS: The mean item difficulty (+/-SD) was -0.878 (+/-1.176), with range of -3.299~0.902. The mean item discrimination (+/-SD) was -1.051(+/-0.392), ranging from 0.346 to 1.848. Discriminations of 19 items were above appropriate level and the delayed recall of short story items of the long-term memory had the highest discrimination. CONCLUSION: All the MiMeT items were thought as having no problems as memory screening test in terms of difficulty and discrimination at the level of p<0.01.

Crossed aphasia refers to disturbances of language following a purely right-hemisphere lesion in right-handed individuals. In right-handed individuals, aphasia is almost invariably related to a left cerebral lesion and crossed aphasia occurs in only 1 percent who developed a sudden left hemiparesis with global aphasia. He has neither family history of left-handedness or ambidexterity. Brain MRI showed an acute large infarct of the middle cerebral artery territory on the right side and brain SPECT disclosed extensive areas of hypoperfusion in the right hemisphere and no abnormal finding in the left hemisphere. The sensory component of language function was almost improved, but the motor component has been changed. Further studies of crossed aphasia may supply more data on the functional organization of the brain for speech and language.

This study was undertaken in order to estimate the accuracy of disease code of the Korean National Medical Insurance Data and disease the characteristics related to the accuracy. To accomplish these objectives, 2,431 cases coded as notifiable acute communicable diseases (NACD) were randomly selected from 1994 National Medical Insurance data file and family medicine specialists reviewed the medical records to confirm the diagnostic accuracy and investigate the related factors. Major findings obtained from this study are as follows: 1. The accuracy rate of disease code of NACD in National Medical Insurance data was very low, 10.1% (95% C.I.: 8.8-11.4). 2. The reasons of inaccuracy in disease code were 1) claiming process related administrative error by physician and non-physician personnel in medical institutions (47.0%), 2) input error of claims data by key punchers of National Medical Insurer (31.3%) and 3) diagnostic error by physicians (21.7%). 3. Characteristics significantly related with lowering the accuracy of disease code were location and level of the medical institutions in multiple logistic regression analysis. Medical institutions in Seoul showed lower accuracy than those in Kyonngi, and so did general hospitals, hospitals and clinics than tertiary hospitals. Physician related characteristics significantly lowering disease code accuracy of insurance data were sex, age group and specialty. Male physicians showed significantly lower accuracy than female physicians; thirties and forties age group also showed significantly lower accuracy than twenties, and so did general physicians and other specialists than internal medicine/pediatric specialists. This study strongly suggests that a series of policies like 1) establishment of peer review organization of National Medical Insurance data, 2) prompt nation-wide expansion of computerized claiming network of National Medical Insurance and 3) establishment and distribution of objective diagnostic criteria to physicians are necessary to set up a national disease surveillance system utilizing National Medical Insurance claims data.
