We herein report a case of keratoderma showing the combined clinical manifestations of striate and marginal keratoderma. The patient was a 18-year-old giri who about a year ago noticed slightly yellowish, well-circurnscribed, hyperkeratotic plaques on the volar aspect of the fingers and palms of both hands in a linear pattern with bands of hyperkeratotic plaques at the edeges of the 2nd fingers. We also found hyperkeratotic plaques on the both soles which were confined to sites of pressure. She denied a history of any chronic pressure or trauma. There was no family member showing the same clinical features. The histopathological findings from the palm, volsr aspect of finger and a sole revealed marked hyperkeratosis, hypergranulosis, and acanthosis.

STATEMENT OF PROBLEM: Glass fiber post is one of recent developments to accommodate esthetic restoration for endodontically treated teeth. This has many advantages over conventional post system in physical properties, esthetic factor, risk of root and restoration fracture, adhesion to core, radiopacity, removal and retrievabilty, biocompatibility and chemical stability. PURPOSE: This in vitro study was to evaluate the most suitable type of resin core for the glass fiber post through surveying the fracture modes and the maximum load that fractures the tooth. MATERIAL AND METHODS: 50 sound maxillary premolars restored with glass fiber posts(ParaPost(R) Fiber White) and different types of resin cores(ParaCore, Z100(TM), Rebilda(R) and Admira(R)) were prepared and loaded to faiure in a universal test machine. The maximum fracture load and fracture mode were investigated in the specimens that were restored with resin and those of metal cast and core. With the data, Wilcoxon rank sum test was used to validate the significance between the test groups, and Tukey's studentized range test was used to check if there is any significant statistical difference between each test group. Every analysis was approved with 95% reliance. RESULTS: On measuring the maximum fracture load of teeth specimens, there was a significant difference between the maximum fracture loads of the tooth specimens. ParaCore showed the highest mean maximum fracture load followed by Z100(TM). And, the distribution of fracture mode of tooth specimens showed generally Type D, the three parted fracture of the core around the post was mostly seen(62.5%), and specifically, ParaCore showed 90% and Z100(TM) showed 100% Type D fracture. CONCLUSION. Referring to the values of maximum fracture load and mean compressive fracture load, ParaCore and Z100(TM) had high values and are recommended as tooth colored resin core material for glass fiber post. CLINICAL IMPLICATIONS: This study was carried out intending to be of aid in selecting the appropriate resin core for the glass fiber post. The dual cure type composite resin ParaCore and light cure type composite resin Z100(TM) have good properties and are recommended as tooth colored resin core material for glass fiber post.

Chronic osteomyelitis continue to be a therapeutic challenge. The osteomyelitis also implies chronic ischemia of the diseased bone ; thus systemic antibiotic treatment may not be as effective as we want. In 1972, Klemm developed a new procedure to supplement saucerization in the treatment of chronic osteomyelitis, alternative to irrigation and suction-drainage, i.e., Gentamicin-PMMA Beads. The authors analysed 35cases of the chronic osteomyelitis which were admitted and treated by sauceriztion and Gentamicin-PMMA Beads in Department of Orthopaedic Surgery, Korea Veterans Hospital from Aug. 1984 to Jan. 1988.

We performed the same day dipyridamole stress/rest myocardial SPECT in 14 healthy young men, reconstructed the polar maps according to Cedars-Sinal method and quantitated the radioactivity of myocardial wall. We divided the whole myocardium to 9 sectors. The latero-anterior wall contains the highest count. The infero-septal wall contains the lowest count. There isn't any significant differences of radioactivity in each segment between stress and rest polar map. The hemodynamic parameters after dipyridamole injection in the subjects were significantly changed except systolic blood pressure : the heart rate was increased and diastolic blood pressure was decreased. Adverse effects were reported in 85.7%. We suggest that these data can be used to dectect perfusion defect in the coromary artery disease.

We studied the incidence and results of treatment of secondary hypertension in Yeungnam University Hospital. Nineteen hundred fifty patients with hypertension were included from march 1990 to march 1994. We analysed the prevalence of secondary hypertension and results of treatment. The incidence of secondary hypertension in Yeungnam University Hospital was six percent. The most common underlying causes of secondary hypertension was renal parenchymal disease. Patients with three forms of potentially reversible secondary hypertension, namely, renovascular hypertension, endocrine disease, exogenous hormone, were assed to determine whether surgery or withdrawal of the exogenous hormane had led to an improvement in blood pressure control. The incidence of secondary hypertension in Yeungnam University Hospital was low(6%), but some of these are curable. Thus it is very inportant that evaluate the secondary hypertension.

BACKGROUND: Although numerous previous studies on the subject have been performed, the correlations between various pathologic findings on magnetic resonance imaging and pain reproduction by provoked discography have not been fully explained. A higher sensitivity and positive predictive value (PPV) of the high intensity zone (HIZ) for predicting concordant pain was reported. Moreover, although the apparent validity of this sign has been corroborated by some investigators, it has been questioned by others. The validity of this sign awaits confirmation. The various pathologic parameters seen on magnetic resonance imaging (MRI) in patients with discogenic lumbar pain was assessed and correlated with observations on discography. METHODS: There were 18 patients enrolled, ranging in age from 28 to 64 years with an average age of 48.8 +/- 10.2 (mean +/- SD) years. Five men (28%) and thirteen women (72%) participated in the study. All patients underwent provocation discography by a standard technique, as mentioned previously. The lumbar discs examined were L3-L4;(2), L4-L5;(14) and L5-S1;(10). The relationship between discogenic lumbar pain and disc morphology was investigated by using MRI and provocation discography. RESULTS: Of the 26 discs being studied, 16 proved to be concordantly painful at discography relative to clinical back, buttock, hip, groin, and proximal leg pain complaints. Fourteen of the 16 painful and concordant pain discs exhibit grade 2, 3 with annular tears, and four with free leakage of contrast into the epidural space. Using chi-square analysis, we observed a significant correlation (P < 0.05) between the annular disruption grade and the provoked pain response. We were not able to demonstrate that the HIZ was associated with any particular grade of disc disruption. Similarly, there was no significant correlation (P > 0.05) between a concordant pain response and the presence of an HIZ regardless of the level and grade of disc disruption. CONCLUSIONS: The presence or lack of the HIZ does not exclude the disc as a source of pain and should not replace provocation discography as a means of evaluating low back pain with or without sciatica.

We experienced a complication of brachial plexus palsy secondary to operative position during thoracoscopic thoracic sympathectomies. His general health was excellent and no previous histories vulnerable to peripheral nerve systems were observed. The thoracic sympathectomies were done under general anesthesia. The patient was placed left lateral position with his right arm abduced 150o on padded arm board. An operation was lasted 2 hours and 30 minutes at this position because of severe right apical lung adhesion. The controlateral side was performed same procedure and lasted 20 minutes. After the patient recovered from the anesthesia, the patient had a complete paralysis of right arm. There was also slightly diminished sensation to pinprick on the arm and hand. Neurologic examination and EMG study revealed brachial plexus palsy. Nerve blocks and physiotherapy were performed to treat brachial plexus injuries. His motor functions were improved day by day and he was discharged with a complete range of motion against gravity on 14th. postoperation day. However, there were loss of muscle powers against some resistances and tingling sensations of fingertips. Two months later, he was recovered completely and there was no residual disabilities.
