Callus is a nonpenetrating circumscribed hyperkeratosis produced by repeated friction or pressure. It occurs on parts subjected to intermittent pressure, particularly on the palms and soles, and particularly over the bony prominences of the joints. In painful callosities of the feet, ill-fitting shoes and orthopedic problems of the foot (bunions, exostoses) are some of the etiological factors to be considered. Gout is a condition of inborn metabolic and/or acquired form of the disease characterized by hyperuricemia, tophaceous deposits of sodium urate and recurrent attacks of arthritis. We present a case of callus caused by tophi. The patient was a 45-year-old man who had complained of a painful, well-demarcated, hyperkeratotic plaque on the heel of the left foot for 18 months. After the tophi beneath overlying whitish thickened skin had been removed, the skin lesion disappeared and to date has not recurred.

Darier disease is a rare genodermatosis clinically characterized by multiple hyperkeratotic papules and plaques predominantly on seborrheic areas. It has characteristic histopathological features; corps-ronds, grains, suprabasal clefts or lacunae, villi projections etc. We present a case of Darier disease in a 36-year-old woman. She had suffered from skin lesions which bore a great resemblance to those of verruca plana or eruptive syringoma. We could confirm the diagnosis as Darier disease because she had the characteristic nail changes.

Although some employees working for Seoul Metropolitan Subway Cooperation are working at the noisy workplaces, they has been excluded from Special Periodic Health Examination Program. And some workers complained of hearing loss or tinnitus. So, this study was carried out to investigate the prevalence rate of Noise Induced Hearing Loss of employees(10,792) working for Seoul Metropolitan Subway Cooperation. The number of subjects were total 10,792 with 10,355 men and 437 women. A questionnaire survey, otological examination, Rinne test, pure tone audiometric tests were performed and through the first and second screening audiometric examination, 605 workers were selected after excluding employees with past otologic problems, recent exposure to high level noise, and under medications. and the results were as follow; 1. Among 10,792 workers, 4 workers(0.037%) diagnosed as NIHL and 601 workers(5.56%) as early NIHL. As workers grew older, the prevalence rate of NIHL and early NIHL became more rising. 2. The prevalence rate of NIHL and early NIHL was different between work site. After age adjustment, The prevalence rate of NIHL and early NIHL was 23.74% in Train repairmen{80dB(A)}, 3.1% in Station staffs{below 70dB(A)}, 2.53% in Train crew{below 70dB(A)}, 2.1% in Office workers. 3. The perception rate of necessities of ear plug in NIHL and early NIHL was below 55% and wearing rate of ear plug in NIHL and early NIHL was 1.1% In conclusion, some employees who was under working environment in Seoul Metropolitan Subway Cooperation should be monitored to prevent hearing impairment and would be needed health education.

BACKGROUND: The purpose of this study was to evaluate the postoperative magnetic resonance imaging (MRI) results of minimal-tying (one medial-row tie among 4 medial-row sutures) on the medial-row in double-row suture-bridge configuration (2x2 anchor with 4x4 suture stands). METHODS: From 2011 March to 2012 July, 79 patients underwent arthroscopic rotator cuff repair using 2x2 anchor double-row configuration. The mean age was 61.3 years (range, 31-81 years). Two double-loaded suture anchors were used for medial-row. Four medialrow stitches were made with only one medial-row knot-tying (the most anterior suture). Lateral-row was secured using the conventional suture-bridge anchor technique; all 4 strands were used for each anchor. Repair integrity was evaluated with MRI at mean 6.2 months postoperatively. Retear and the pattern of retear, change of fatty infiltration, and muscle atrophy of supraspinatus were evaluated using pre- and postoperative MRI. RESULTS: Repaired tendon integrity was 38 for type I, 30 for type II, 6 for type III, 4 for type IV, and 1 for type V, according to Sugaya classification. Considering type IV/V as retear, the rate was 6.3% (5 out of 79 patients). Medial cuff failure was observed in 4 patients. Fatty atrophy of supraspinatus was significantly improved postoperatively according to Goutallier grading (p=0.01). The level of muscle atrophy of supraspinatus was not changed significantly after surgery. CONCLUSIONS: Minimal tying technique with suture configuration of four-by-four strand double-row suture-bridge yielded a lower retear rate (6.3%) in medium to large rotator cuff tears.

10.A cephalometric study of the natural head position according to craniofacial morphology.
Korean Journal of Orthodontics 1987;17(1):55-62
Diagnosis and treatment plans of patients are depended on cephalogram in most case. How?ever, conventional cephalogram may change diagnosis because it ignores a conception of natural head position. The purpose of this study was to investigate the difference of head positions between conventional X-ray taking and x-ray taking in natural head position, and correlation between above results and craniofacial morphology 60 male students in dental college, Yonsei Univ were selected, and every cephalogram is studied by comparison of the change of head position. The results are as follows 1. When taking X-ray by using conventional method, external auditary meatus FH was more tilted than ear rod FH by 21degrees +/-1.8 in forward and downward direction. 2. As facial form becomes concave, natural head position and head position, appeared in X-ray taking by using conventional method, become more similar. 3. Change in head positron had showed high correlations with facial form (N-A-Pog angle), and there was high significance to concave group when compared with average group, but significance to convex group was not found. 4. Multiple-regression equation concerning change of head position was solved deltaFH = 24.5 + 0.31 NAPog + 0.43 Prominence of Chin + 0.13 Facial length -0.32 Anterior facial height.
