Reconstruction of the auricle is one of the most fastidious fields in plastic and reconstructive facial surgery, because the ear is made up of complex cartilage framework arid its thin skin envelope. Insertion of carved rib cartilage is the most popular method for framework fabrication. But it has some disadvantages such as donor site morbidity, lesser flexibility of rib cartilage, difficulty in carving structure and distortion of cartilage after calving. Furthermore surgeon's talent and sufficient practice are necessary for a satisfactory result. So we introduced the concept of perichondral graft to improve the framework fabrication. In 1972 Skoog and associates reported that free perichondral grafts could be used to produce new cartilage. And several other reports supported the chondrogenesis of free perichondral graft. We molded the human ear using silicone rubbed impression material. And the eat mold was wrapped up in perichodrium of rabbit ear and placed in a subcutaneous pocket in formes of graft and flap. Six and eight weeks later, rabbits were sacrified and the newly formed cartilage framework was harvested. Grossly it showed the same appearance as the human eat and elastic property of normal cartilage. In histologic examination, it showed mature structure of normal cartilage; large lacunae containing spherical chondrocytes surrounded by well defined capsule.

It has been Known that silicone intubation may be an effective procedure for total or partial obstruction in infants of age one year or less, and the older the patient, the lower the success rate. We had performed silicone intubation on 40 eyes of 39 patients from january 1995 to May 1996, and they were divided into 3 groups according to age: group 1, 6 months to 6 years: group 2,6 to 16.: group 3, one 16 years. The success rate was 92.4% in groups 1 and 2, respectively: 83.3% ingroup 3. The success rate in patients with partial obstruction in group 3 was 100% In view of the results of the present study, silicone intubation may be in primary procedure for partial obstruction of lacrimal drainage system.

Systemic lupus erythematosus is a connective tissue disease which can affect every organ system. Neurologic abnormalities are common, occuring in approximately half of all patients at some time during the course of their illness. But symptoms of nervous system as the sole presenting symptoms occur in less than 1% of lupus patients. In patients initially presenting with neurologic symptoms and signs, differential diagnosis is difficult and sometimes it may be misdiagnosed. Therefore extensive laboratory investigations should be carried out in all patients with unusual neurological symptoms, since early diagnosis of lupus can help in providing effective treatment. We report a patient with systemic lupus erythematosus who presented with dysarthria and dysphagia resembling multiple sclerosis.

OBJECTIVES: This study was performed to investigate the effectiveness of the questionnaire. METHODS: Workers'health examination records, work environment record, and questionnaires of selected industries as samples were analysed using logistic regression analysis and discrimination analysis Results'Cases of bearing impairment (Dl+C) as dependent variables, and age, work duration and level of environmental noise as independent variables were selected for multiple unconditional logistic regression analysis. Odds ratio was 4.04 in hearing difficulty, 2.78 in tlnnitus and 1.08 in age. In the second analysis Noise induced hearing loss is selected as dependent variable. The OR in hearing difficulty was 3.67(95 % C.1. : 1.61 8.61), and was 1.09(95 % C.1. : 1.05-1.14) in age. Conditionnal multlple logistic regression analysis was performed. In hearing impairment as dependent variable, the OR of age was 1.02(95 % C.1. : 1.00-1.04) and other variables were not significant. However, NIHL as dependent, the OR of hearing difficulty was 4.57(95 % C.1. : 1.43-14.67). According to multiple logistic regression adopting each items of questionnaire as dependent variable, the only item of hearing difficulty showed significant difference with hearing ability. The discrimination analysis was performed with the class variable of hearing impairment, and discrimination variables of age, work duration, and environment noise level. The sensitivity of 59 %, and specificity of 88 %, and average error count of 23 % were obtained. When the numbers of items answered in questionnaire were assumed as the parameter of judgement for noise induced hearing loss (NIHL), the highest sensitivity and specificity were 33.5% and 49.0% in cases of more than two items answered. CONCLUSIONS: The development of items that is simple and discriminative mainly consisted of chronic and specific diseases related items is needed. Computerization for newly developed items might be needed to establish effective surveillance system for NIHL in the future.

BACKGROUND: The purpose of this study was to investigate the difference between two nailing approaches of intramedullary screw fixation, the retrograde nailing versus the anterograde nailing, on the radiological and clinical outcomes in patients with clavicle shaft fractures. METHODS: From April 2002 to August 2014, we enrolled a total of 22 patients with clavicle shaft fractures to participate in this study. Twelve patients received retrograde intramedullary nailing and 10 received anterograde nailing. The average duration of follow-up was 12 months. In all the patients, we took follow-up radiographs of the anteroposterior and the axial views to assess the postoperative radiological outcomes. We measured the visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and the range of motion (ROM). RESULTS: Clinically, we did not find a statistically significant difference in the retrograde group and the anterograde group in terms of the duration to bone union, the VAS score the ASES score and the ROMs. Radiologically, we found that the difference in the clavicle shortening of the affected arm and the unaffected arm did not show a statistically significant difference at the immediate postoperative assessment. we found that the difference in the clavicle shortening of the affected arm between the immediate postoperative and the final follow-up value did not show a statistically significant difference. CONCLUSIONS: We found that both the retrograde nailing and the anterograde nailing gave a favorable outcome for clavicle shaft fractures. Although we saw evidence of clavicle shortening after intramedullary screw fixation, this was not a factor that influenced clinical outcome.

The etiology of benign prostatic hyperplasia( BPH) is multifactorial, but it is recognized that two important factors necessary for the induction of BPH in men are the testis(endocrine control) and the aging. From January 1991 to June 1992, we measured 6 hormonal factors in the serum of 129 men who were diagnosed as benign prostatic hyperplasia pathologically to determine whether endocrine factors influence the volume of benign prostatic hyperplasia. These hormonal levels were correlated with the prostatic volume measured by transrectal ultrasound(TRUS). There was no significant correlation for age with total prostatic volume(r=0.06, p=0.31l). With age there was a significant increase in serum testosterone(r=0.25, p=0.003), LH(r=0.42, p=0.000) and cortisol(r=0.25, p=0.016). The prostatic volume measured by prostatic ultrasound was correlated positively with estradiol(r=0.34, p=0.002) and cortisol(r=0.28. p =0.008). Also the prostatic volume was correlated with resected weight of prostate(r=0.38, p=0.000). We suggested that serum estrogen and cortisol levels may be the factors in persistent stimulation of benign prostatic hyperplasia.

PURPOSE: To present the enhancement pattern of acute cerebral or cerebellar cortical infarctions aged 1-3 days on MR. MATERIALS AND METHODS: Contrast-enhanced MR images of 26 patients with acute cerebral or cerebellar ischemic events were retrospectively reviewed. MR was performed within 3 days after ictus. RESULTS: Contrast enhancement in the area of infarction was observed in 61.5% (16/26) on MR. Of these 50% (13/26) showed non-parenchymal enhancement (NPE) representing either vascular or leptomeningeal enhancement, 7.7% (2/26) showed parenchymal enhancement (PE), and 2.8% (1/26) showed both NPE and PE. The earliest enhancement was seen in images obtained 12 hours after the onset of symptoms and appeared as NPE. One patient showed NPE without apparent high signal intensity at the corresponding area on T2-weighted images. In 38. 5% (10/26), there was no enhancement. CONCLUSION: Contrast-enhanced MR imaging may be needed in acute ischemic infarction, because NPE may be seen as the earliest MR finding of acute cortical infarction aged 1-3 days.

To know the pattern of visual field (VF) defect of low tension glaucoma (LTG), its diffuse and localized VF defects were compared using the significance values (p-value) of mean deviation (MD) and corrected pattern standard deviation (CPSD), which are calculated with STATPAC in Humphrey Visual Field Analyser. Sixteen eyes of LTG were enrolled and 34 eyes of primary open angle glaucoma (POAG) were used as controls. The degree of VF defects in LTG and POAG was relatively mild with the p-value of MD equal to or greater than 1%. Neither mean MD nor mean CPSD of LTG was significantly different from each of POAG (p > 0.8 and p > 0.2, respectively). Comparing the p-values of MD and CPSD, many patients showed more significant p-value of MD in LTG and POAG (62.5% and 61.8%, respectively). However, relatively more severe defect of CPSD tended to occur more frequently in LTG than in POAG (25% and 5.9%, respectively, chi-square = 4.964, p < 0.09). The relation between p-values of MD and CPSD was not significantly influenced by the intraocular pressure, MD or vertical cup to disc ratio in either LTG or POAG.
