Supracondylar fracture is the most frequent injury of the elbow and frequently accompanies complications in children. Seventy two cases of supracondylar fractures have been treated and managed at Department of Orthopaedic Surgery, Catholic Medical College during the period from Jan. 1969 to Dec. 1972. The evaluation of fracture was done according to the classification of Holmberg and Hoyer. Among 72 cases of the supracondylar fracture, the most common type is 29 cases of Grade 2: (40.2%). Most cases were treated conservatively, and various method of treatment were adopted according to the condition of fracture. Residual angular deformities after successful manipulative reductiion can be accurately evaluated roentgenographically by the Baumanns method. Good results were obtained in 62.6%, fair results in 33.3%, and poor results in 4.1%. The incidence of cubitus varus deformity is 37.5%. There were no instance of ischemic contracture and no permanent neurological deficit in fracture cases.

Access to the craniofacial skeleton and skull base requires osteotomies. An adequate exposure of neoplasms occupying the skull base and the oral cavity and oropharynx, especially retromolar trigone, is very important for precise tumor ablation. The demonstration by Tessier of the capacity for large segments of bone to survive removal and replacement has enabled skull base tumor surgery to grow into a subspeciality. Through the refined craniofacial exposure osteotomies, the surgery is safer, the operation shorter, and the result better both oncologically and reconstructively. We experienced 24 cases of exposure osteotomies consisting of 12 cases transzygomatic approaches, 1 case tranglabellar osteotomy, 1 case lateral transmaxillary approach, 1 case Le Fort II & midline splitting, and 9 cases mandibulotomy. There was no significant complication except a local wound infection in transzygomatic approach and one case of minimal malocclusion after parasymphyseal mandibulotomy. The orthotopic bone graft and the rigid fixation enables the postoperative morbidity to decrease. It seems that the previously inaccessible craniofacial tumors can be treated through the various exposure osteotomies.

OBJECTIVE: The purposes of the present study were to investigate the effect of gamma-radiation on the expression of inhibin-alpha proteins and genes for inhibin alpha, betaA, and betain the ovary. METHODS: Immature mice were whole-body gamma-irradiated with 25% of a lethal dose. At time 0, 3, 6, 12, and 24 hours after the irradiation,the ovaries were collected and used for immunohistochemistry for inhibin-alpha, and RT_PCR for inhibin-alpha, betaA, and betaB. RESULTS: The expression of the immunoreactive inhibins-alpha was maintained at 12 hours post-irradiation and reduced thereafter. The expression of inhibin-alpha mRNA was significantly increased with the time after the irradiation. However there were no significant changes in the expression of betaA and betaB mRNAs. CONCLUSION: It might be thought that inhibin acts as one of the regulatory factors in the gamma-radiation-induced follicular atresia in mice

BACKGROUND & PURPOSE: Of thalamic stroke syndrome, according to previous reports, the syndrome of hemiataxia and hemisensory loss (thalamic ataxia syndrome) is known to have localizing value confined to the lesion of posterolateral thalamus. And ataxia in thalamic ataxia syndrome is due to interruption of cerebellar outflow pathways. We observed the clinical characteristics of cerebellar manifestations in patients with thalamic ataxia syndrome to clarify intrathalamic cerebellar pathways because it is known that parts of cerebellar efferent fibers do not pass through the thalamus. METHODS: Ten patients with ataxia (5 men, 5 women ; mean age 64), out of 47 thalamic stroke patients admitted to Kyung Hee University Hospital from Jan. 1994 to May. 1995, were selected. The localization of the lesion was based on CT or MR imaging and ataxia was characterized in view of cerebellar functions - coordination of movement, regulation of equilibrium and muscle tone. RESULTS: Out of 10 patients, 4 patients were thalamic hematoma, 4 patients thalamic hematoma with intraventricular hemorrhage, 2 patients thalamic infarction. Four patients were hemiataxia-hemiparesis-hemisensory loss, 4 patients hemiataxia-hemisensory loss, 2 patients hemiataxia-hemiparesis. Posterolateral thalamus was involved in 4 patients, dorsal thalamus in 3 patients, posterolateral and dorsal thalamus in 3 patients. All patients had dysmetria, dysdiadochokinesia, kinetic tremor. Two patient has gait ataxia. Speech and ocular motility disturbances were not noted. CONCLUSION: Thalamic ataxia syndrome appeared in the lesion of posterolateral and dorsal thalamus. Common cerebellar manifestations symptoms of incoordination.

BACKGROUND: Catheterization of central vein may cause fetal complications such as cardiac arrhythmia, cardiac temponade, atrial perforation etc. For prevention of these complications, tip of central venous catheter should located in superior vena cava. The purpose of this study was to investigate the optimal positioning of central venous catheters. METHOD: From March 1996 to Jun 1996, a total of 50 patients who requiring central venous catheters were involved. First, we evaluate the accuracy of predetermined formula of 'Peres'. Second, we hypothesized that height of patients was correlated with optimal length of central venous catheters and we analysed relationship between height and optimal length of central venous catheters using simple regression analysis by SAS. RESULTS: 1) Predetermined formula of 'Peres' inaccurately predicted required length of central venous catheter. The accuracy was 78%. 2) There were a linear relationships between height and optimal length of central venous catheter. Their relationships was followed, Y=0.09X(Y: optimal length of central venous catheters, X: height, p=0.0001, R2=0.39). CONCLUSION: Using height of patients, we can accurately predict the optimal length of central venous catheters.

Cardiac myxoma is a rare but potentially treatable cause of stroke. The diagnosis is rarely made on typical triad of constitutional, embolic, and obstructive symptoms, and it is difficult because there is no specific history, physical examination, chest X-ray, or electrocardiographic findings, but with the development of echocardiography the correct diagosis is now usualy made. Neurologic manifestation is frequent(25-45%) and presented with embolic infarction, aneurysm formation, intracranial hemorrhage, and distant metastasis. We experienced five patients with cardiac myxoma who presented with these neurologic manifestations. Also we should be considered in the differential diagnosis of cerebral infarction, particularly when multiple cerebral infarction and constitutional or obstructive symptoms are conjoined in young age stroke. We describe five patients who presented with embolic infarction, cerebral metastasis and aneurysm formation.

In May 1974, authors encountered a 37 year old Korean male who was suffering from very serious condition of acute abdomen. On exploratory laparotomy, a ruptured granulomatous mass in the proximal portion of the ileum showing extensive inflammatory and gangrenous changes was found and about 4 ft. long of the bowel was resected. From the honey-combed fibrous capsules in the mass, four plerocercoid larvae, spargana, measuring about 3 to 7 cm in lengths were extirpated. The patient had a past history of having eaten the raw flesh of a snake as a tonic about 7 months prior to admission. Four cases of intra-abdominal sparganosis reported previously in Korea and the present case were discussed briefly. Snakes and frogs in Korea are very important second intermediate hosts for the 1arva, Sparganum stage. It is most preferable that the habitual ingestion of the raw fleshes of them should be avoided in this country.

Psoriasis is characterized by disregulation of keratinocyte growth with profound epidermal hyperplasia. Keratinocyte hyperplasia in psoriasis may be expained in part by overproduction of growth factor, and by altered metabolism of the epidemal growth factor receptors (EGFR) in affected skin. The expression of epidermal growth f ictor receptor was investigated by Northern blot and slot-blot analysis of total RNA extrated from biopsies of normal skin and psoriatic lesions. In Northern blot analysis, EGFR-specific mRNA transcripts from psoriatic tissues demonstrated the specificity of hybridizarion with a EGFR mDNA probe. The size of EGFR mRNA transcript was 6.7kb in psoriasis lesions which showed no change of quality. In slot-blot analysis, the levels of EGFR mRNA in poriasis revealed a 1.2 fold to 4.1 fold elevation when compared to normal skin. EGFR were present in all epidermal layers by immunoperoxidase staining, whereas in normal skin they were primarily present in the stratum basalis. These results indicate that the increased expresion of the EGFR gene may be, in part, responsible for the hyperproliferation of the epider nis and that retained EGFR may reflect incomplet; abnormal differentiation in active porasis. This altered process of EGFR metabolism may be involved in the pathogenesis of psoriasis.
