The occurrence of fistulous tract between the thoracic subarachnoid space and the pleural cavity due to injury is uncommon. The one was developed after traffic accident and treated by surgical repair of the fistula : The other was post-operative complication of costotransversectomy for T2 sympathectomy. The complication was realized by the surgeon who was aware of the small leakage of cerebrospinal fluid from the dura propria of the T2 nerve root at the time of surgery. Intermittent pleural punctures for drainage and semisitting position were followed by spontaneous closure of the fistula. These cases were reported so that the uncommon condition might be added to the differential diagnosis of pleural effusion.

Since the fact was known that mouth breathing resulted from the adenoid hypertropy causes malocclusion, many investigators have studied nasopharynx and adenoid in order to clatify the role in relation to the effect on face and coolustion and the development of arrway. The author analyzed 13 items in longitudinal cephalometric roentgenograms of 17 boys and 19 girls taken from the age of 7 to 12. The results were as follows. 1. The means and standard deviation for the measured items were obtained. 2. The continual growth of nasopharyngeal cavity was more affected by the height than the depth. 3. The size of adenoid was larger in males than in females, especially on R, D-AD2. 4. Airway percentage was highest in boys at age 10 and girls at age 9. 5. The items showed significant differentiation between males and females were airway percentage, posterior height, D-AD1, D-AD2, and R.

The purpose of this study was to investigate the fittness of Golden relation items was advocated by Ricketts whether or not it is applicable to the young adult Korean dentitions and also to evaluate the several new Golden relation items conducted by the author. The material was consisted of 81 dental casts (34 male, 47 female) with ideal occlusion, which never undergone orthodontic, prosthodontic procedures. Measurements were made on the arch dimensions using sliding caliper (Mitutoyo Co) and data were computerized and analyzed. The findings of this study were as follows, 1. The Golden proportion advocated by Ricketts dose not seem to directly applicable to the Korean normal dentition, however, the modification from the Ricketts' original shows the Golden proportion as follow. A first series of progressive Golden relations was found on the Golden ratio among the lower central incisors width, the inter mesioincisal width of the upper lateral incisors, and the upper first premolars width. A second series was found on the Golden ratio among the lower lateral incisors width, lower inter canine tips width and theupper first molar distal cusp tips width. A third series was found on the Golden ratio between the inter distal aspect width of lower canine and the mesial cusp tips width of the lower second molars or inter cusp tips width of upper second premolars. 2. In addition to RIcketts' original, 4 new Golden proportions were found in young adult Korean dentition, these are as follows, The tips of lower canine width had Golden relation with the width of the upper first premolar buccal cusp tips or the width of the lower first molar central fossae. The distal aspect of the lower first premolars had Golden relation with the buccal surface widths of the lower or upper second molars. The width of upper lateral incisors had Golden relation with the upper second molar height. The width of the lower canine tips had Golden relation with the lower second molar height.

Accompanying to the development of the knowledgment of mechanism and pathology of recurrent dislocation of the shoulder, accurate diagnostic tools to detect that pathology have been developed. During the period from May 1990 to May 1992, we treated 28 cases of recurrent anterior dislocation of the shoulder. Twenty-eight cases were examined with C.T. arthrography before the operation. Among the 28 cases, we identified the Bankart lesion in 20 cases by C.T. arthrography, and in 21 cases intraoperatively. We concluded that the C.T. arthrography is an accurate method for confirming the clinical diagnosis of recurrent dislocation of the shoulder and to be helpful in detecting the Bankart lesion and its severity or pathologic findings.

PURPOSE: To analyze angiearchitecture of arteriovenous malformations(AV malformation) in order to clarify the angiegraphic risk factors for intracerebral hemorrhage and other nonhemorrhagic symptoms. MATERIALS AND METHODS: Eighty-five patients with angiegraphically-proved brain arteriovenous malformation were included in this study. Retrospective review of clinical history and angiography was done. Topographic analysis and evaluation of 17 angiearchitectural characteristics were conducted. RESULTS: Deep-seated and cortico-callosal type, small nidus size, intranidal pouch, one draining vein, deep venous drainage only venous stenosis and venous aneurysm were the most discriminating or predictive characteristics of hemorrhage in brain arteriovenous malformation. And those with large nidus size, dural supply and venous hypertension were correlated with nonhemorrhagic symptoms such as seizure, headache and neurologic deficit. CONCLUSION: Detailed analysis of the angiearchitecture of brain arteriovenous malformations is needed to identify the features that are correlated with prognostic implications for the treatment of patients with ^V malformations.

PURPOSE: To investigate the toxicity of a short-term application of timolol maleate, dorzolamide, and benzalkonium chloride (BAC) on human conjunctival epithelial cells in vitro. METHODS: Chang's conjunctival epithelial cell line was treated for 5 min, 15 min, 30 min, and 60 min with various concentrations of timolol, dorzloamide, or BAC, and then examined 4 hrs or 24 hrs later. Cell viabilities were assessed by MTT assay. The expressions of various cytokines by timolol maleate, dorzolamide, and BAC treatment in human conjunctival epithelial cells were evaluated using ELISPOT. RESULTS: BAC significantly decreased survival of conjunctival epithelial cells in a dose and time dependent manner compared with timolol and dorzolamide. Inflammatory cytokines, IL-6 and IL-8, were highly expressed in conjunctival epithelial cells treated with timolol, dorzolamide, and BAC. CONCLUSIONS: The present study suggests that increased expression of inflammatory markers, IL-6 and IL-8 might explain the ocular surface disorder in patients receiving antiglaucoma medication.

This study was undertaken to investigate the growth change of gonial angle and interrelationship between the growth change of gonial angle and IMPA in the longitudinal data from 7 years to 15 years. By analyzing the serial lateral cephalograms of 15 males and 18 females of 7 years old to 15 years old who had no abnomality in growth and development and no history of orthodontic treatment, the following conclusion were obtained. 1. Gonial angle gradually decreased with aging in 25 children and in 9 children increased or maintained. 2. There was a tendency that children who decreased gonial angle with aging showed gradual increase of IMPA and children who increased of maintained gonial angle with aging showed decrease of IMPA 3. There was a tendency that regardless of the change of gonial angle, interincisal angle decreased with aging.

BACKGROUND AND OBJECTIVES: Coronary artery disease (CAD) is a major cause of heart failure associated with left ventricular systolic dysfunction (LVSD). The prognosis of LVSD is significantly influenced by the etiology of heart failure and therefore, differentiation of significant CAD from other etiologies is important. Carotid intima-media thickness (IMT) and plaque are useful predictors for cardiovascular events, including stroke and CAD. The purpose of this study was to evaluate the predictive value of carotid IMT and plaque for the diagnosis of CAD in LVSD patients. SUBJECTS AND METHODS: Seventy-three (n= 73, 47 male, 67.6+/-12.4 years) patients hospitalized for heart failure with severe LVSD were retrospectively enrolled. The severity of CAD was analyzed by the Duke Jeopardy Score system, and carotid IMT and plaque were measured according to the Mannheim Carotid IMT Consensus. RESULTS: Significant CAD was found in 41 patients (56.1%, CAD group) on coronary angiography. Mean common carotid artery (CCA) IMT (0.74+/-0.05 mm vs. 1.04+/-0.04 mm, p<0.01) was significantly higher in the CAD group. Plaque in CCA (6.25% vs. 19.5%, p<0.01) and plaque in bulb (25.0% vs. 60.9%, p<0.001) were significantly higher in the CAD group. Mean CCA IMT {odds ratio (OR) 2.61, 95% confidence interval (CI) 1.134-4.469, p<0.01} and plaque in bulb (OR 4.69, 95% CI 1.702-12.965, p<0.01) were significant predictors for the diagnosis of CAD according to multivariate logistic regression analysis. CONCLUSION: In patients with severe LVSD, mean CCA IMT and bulb plaque can be useful additional predictors for the diagnosis of CAD.
