The elbow region is the most common site at which the ulnar nerve is prone to a localized neuropathy. Diagnosis of ulnar nerve entrapment at elbow is made on the basis of history, lacal neurologic finding, nerve conduction studies and electromyography. Electrophysiologic test is simple, relatively quick, and accurate method for the diagnosis of peripheral nerve lesion. Therefore, electrodisgnosis makes it possible to identify and localize the early stage of entrapment lesion. Definitive diagnosis of ulnar nerve entrapment at elbow requires electromyographic demonstration of decreased ulnar nerve conduction velocity across the elbow and depressed sensory nerve action potentials. The purpose of this study were to analyze the electrophysiologic findings of patients with an established ulnar nerve entrapment at elbow compared to normal eonduction velocity of our laboratory. And we evaluate the correlation of clinical symptom with the electromyographic findings. Twenty five subjects were studied, 22 men and 3 women, aged from 5 to 62 years. The results were as follows . 1. The mean motor conduction velocity of ulnar nerve across elbow were 32.85±10.21 m/sec. The longer duration of symptom were, the slower conduction veloctity across elbow were. 2. Among the 25 patients, motor conduction velocity of ulnar nerve at forearm segment decreased in 15 patients(60%). As the motor conduction velocity of the ulnar nerve across elbow became slower, thst of forearm segment were slower. 3. In 19 patients (76%) among the 25 patients, sensory evoked potentials revealed prolonged distal latency or were not evoked. 4. On needle electrodiagnostic study, positive sharp wave or fibrillation potentials could be found in abductor digiti minimi first dorsal interosseus and/or flexor carpi ulnaris muscles in 22 patients(88%).

Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

An immunohistochemistry for S-100 protein by biotin avidin system technique was done to evaluate the existence and distribution pattern of S-100 protein positive cells in various obtained were as follows. 1) Positive immunostaining for S-100 protein was observed in myoepithelial cell, serous acinar cell and nervous bundle in normal salivary gland. 2) Strong immunoreactivity for S-100 protein was shown in plemorphic adenoma, which was localized not only in myoepithelial cord or sheets of epithelial portion but also in chondrocytes, stellate cells of myxoid stroma and in squamous keratin pearl of mesenchymal metaplastic foci. 3) The S-100 protein was demonstrated in the tumor cells of tubular adenoma, acinic cell tumors and in epidermoid area of mucoepidermoid tumors. 4) Immunoreactivity for S-100 protein, however, was not found in the tumor cells of adenoid cystic carcinoma and adenolymphoma except for stroma reticulum cells. 5) Intensity of positive reaction for S-100 protein varied from cell to cell: Some had intense immunoreactivity, whreas others were only weakly positive or completely negative, even in myoepithelial cell nest of the same pleomorphic adenoma.

Pityriasis rosea is sometimes accompanied with considerable pruritus. Ultraviolet B irradiation is reported to be beneficial in relieving pruritus. The purpose was to evaluate the effect of UVB phototherapy on severe pruritus of pityriasis rosea. Nine patients with severe pruritus had UVB irradiation three times a week Five patients became symptom free and three showed a marked improvement. One dropped out. UVB phototherapy could be an effective modality for relieving pruritus in pityriasis rosea.

A 60-year-old man with advanced esophageal cancer was admitted for surgical placement of a feeding jejunostomy tube before commencement of chemoradiotherapy. His esophageal cancer had directly invaded the posterior tracheal wall, inducing a nearly total obstruction of the distal trachea. On the day before the surgery, respiratory failure developed due to tumor progression and tracheal edema. Tracheal intubation and mechanical ventilation were attempted without success. Application of veno-venous extracorporeal membrane oxygenation (ECMO) corrected the patient's respiratory acidosis and relieved his dyspnea. With full ECMO support, he underwent tracheal stent insertion. Two hours later, he was weaned from ECMO support uneventfully. This was a successful case of tracheal stenting for airway obstruction under rescue veno-venous ECMO.

PURPOSE: This cross-sectional study was designed to identify anger-expression typesof adolescent women and investigate the relation between the identified anger-expression types and their problem behaviors and health status. METHOD: One hundred ninety nine high school freshmen were recruited from September to November, 2003. Data wasanalyzed using descriptive statistics, cluster analysis, chi-square-test, ANOVA, and Duncan's multiple comparison test. RESULT: Three anger-expression types in adolescent women were found; Anger-out/in, Anger-control/in, and Anger- control type. Adolescent women with frequently using the anger-out/in type and with higher state anger reported more delinquent behaviors, more health risk behaviors, and higher psychosomatic symptoms. However, adolescent women with lower state anger and frequently using the anger-control type reported more depression scores. CONCLUSION: There is a need to further clarify the relationship between anger-expression typesand depression in adolescent women. The findings suggest the necessity of a development of the program for lowering the anger level and controlling the unfavorable anger expression types such as the anger-out in.
