BACKGROUND: Kirschner's wire (K-wire) transfixation and locking hook plate fixation techniques are widely used in the treatment of acute acromioclavicular joint (ACJ) dislocation. The purpose of this study was to compare the clinical and radiologic outcomes between K-wires transfixation and a locking hook plate fixation technique. METHODS: Seventy-seven patients with acute ACJ dislocation managed with K-wire (56 shoulders) and locking hook plate (21 shoulders) were enrolled for this study. The mean follow-up period was 61 months. RESULTS: At the last follow-up, the shoulder rating scale of the University of California at Los Angeles (UCLA) was higher in patients treated with locking hook plate than with K-wires (33.2 +/- 2.7 vs. 31.3 +/- 3.4, p=0.009). In radiologic assessments, coracoclavicular distance (CCD) (7.9 mm vs. 7.7 mm, p=0.269) and acromioclavicular distance (ACD) (3.0 mm vs. 1.9 mm, p=0.082) were not statistically different from contralateral unaffected shoulder in locking hook plate fixation group, but acromioclavicular interval (ACI) was significant difference. However, there were significant differences in ACI, CCD, and ACD in K-wire fixation group (p<0.001). Eleven complications (20%) occurred in K-wire transfixation group and 2 subacromial erosions on computed tomography scan occurred in locking hook plate fixation group. CONCLUSIONS: ACJ stabilization was achieved in acute ACJ dislocations treated with K-wires or locking hook plates. Locking hook plate can provide higher UCLA shoulder score than K-wire and maintain CCD, and ACD without ligament reconstruction. K-wire transfixation technique resulted in a higher complication rate than locking hook plate.

Porokeratosis is a specific disorder of keratinization characterized histologically by the presence of a cornoid lamella. Clinically, the basic lesion is a sharply demarcated hyperkeratotic plaque which may be linear, punctated, or annular with central atrophy. The etiology of the various types of porokeratosis is unknown. However, heredity, UV radiation, immunosuppression, trauma, burns, and occult infection are known to be precipitating or exacerbating factors. A 32-year-old female was burnt on her right arm and chest at the age of 12. Several years later, brownish plaques developed in these burn areas. Seven years prior to visiting our clinic, nu- merous match-head sized, peripherally elevated macules developed on the forearms and have gradually spread to the other areas of her upper and lower extremities. The histological findings of two lesions from the burn areas showed the same features including cornoid lamellae in the epidermis and fibrosis in the dermis. Howerer, the histological finding of a lesion from a non-burn area showed cornoid lamellae in the epidermis without evidence of dermal fibrosis. We believe our case is the first to be reported in Korea in which porokeratosis arose in previous burn areas.

In order to evaluate the hypotensive effect of the lisinopril, a long acting angiotensin converting enzyme inhibitor, 10 to 30mg of lisinopril were administered in 35 hypertensive Korean adults during six weeks after a week observation for washout with stepwise increments of the dose according to the response of the patients blood pressure in every two weeks. The results were ; 1) The supine blood pressures were decreased from 163.7+/-16.6/99.8+/-9.3mmHg to 140.7+/-15.5/87.4+/-9.9mmHg at the end of six weeks' drug therapy(p<0.001). The standing blood pressures were also decreased conferrably and to the some lower levels. 2) In 14 patients to whom the drug was administered longer period(12 to 28 weeks) the blood pressure lowering effects were maintained at the level of that of 6th week. 3) Hematologic examination and blood chemistry revealed no discernible abnormal findings before and after the treatment. 4) In those patients who showed no adequate blood pressure control with other classes of antihypertensive drugs the lisinopril was effective in lowering their blood pressures by adding small doses. 5) During the period of the study a few probably drug-related symptoms developed but not troublesome except dry cough and dry mouth shich forced to stop administering the drug after completion of six weeks' period in one patients. From above results we concluded that lisnopril is effective and safe for the treatment of hypertension in Korean adults.

OBJECTIVES: To examine the tooth whitening effects of a 3% hydrogen peroxide gel.METHODS: Twenty participants were given experimental tooth whitening gels containing 3% hydrogen peroxide, and another 20 participants, who served as the control group, were given tooth whitening gels that contained no hydrogen peroxide. Both groups used their respective whitening agents for 1 week, and tooth lightness was examined at baseline and 4 and 7 days after the experiment.RESULTS: Compared with the control group, in the experimental group, lightness values, determined using VITA classical A1-D4® and VITA SYSTEM 3D-MASTER®, were significantly increased after using the 3% hydrogen peroxide whitening agent (P < 0.01) both 5 and 7 days post-application (P < 0.05).CONCLUSIONS: The study findings confirmed that an improved tooth whitening effect could be expected with the use of a new type of whitening gel containing 3% hydrogen peroxide.

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

BACKGROUND: Coronary arterioveonus fistula(CAVf) is a rare congerital coronary artery anomaly in adults. CAVF is related with some clinincal significances, such as angina, congestive heart failure and bacterial endocarditis. METHOD: We analyzed clincial characteristics in 10 patients(mean age=52.1 +/- 12.5 year) of adult CAVF, who were diagnosed as CAVF by coronary angiogram from Jan. 1993 to Mar. 1997 in Chonnam University Hosptial. RESULTS: Five out of 10 patients complained of chest pain, four had dyspnea and one had hemoptysis. In seven patients, arteries of CAVF were originated from left coronary arteries, from right coronary artery in one, and from both coronary arteries in two. CAVF was drained into pulmonary artery in six patients, right ventricle in two, right atrium in one, and left ventricle in one. CONCLUSION: Chest pain and dyspnea are common in symptomatic patients with CAVF are originated most commonly from left coronary arteries and drained into pulomonary arteries in Korean adults.
