STUDY DESIGN: Thirteen patients with cervical interlocked facets dislocation in whom closed reduction by skull traction was failed were evaluated about the patterns of ruptured disc fragment. Objects : To evaluate the causes of failure at closed reduction, and the relation between ruptured discs and interlocked facets, and the treatment results through an anterior approach. SUMMARY OF LITERATURE REVIEW: In traumatic dislocation of the cervical facet joints, spinal cord or nerve roots injury associated with the ruptured disc fragment has been reported. However, there is few report evaluating the patterns of ruptured disc fragment as a cause of reduction failure. MATERIALS AND METHODS: Between 1988 and 1997, thirteen patients were treated by anterior fusion with plate after complete removal of the intervertebral disc through anterior approach and reduction of interlocked facets by O1iveira method. They have been followed for an average of 36 months(range : 12-96 months). The interlocking was bilateral in seven cases and unilateral in six cases. We assessed the types of ruptured disc fragment by preoperative MRI and CT and the clinical and radiological results. RESULTS: Ruptured disc fragment was found in all thirteen patients with interlocked facets dislocation. The patterns of ruptured discs were within the uncovertebral joints in 5 cases, posterioly under the posterior longitudinal ligament in 3 cases, anteriorly under intact anterior longitudinal ligament in 3 cases and combined under the anterior and posterior longitudinal ligament in 2 cases. The displacement of ruptured disc fragment were seemed to be the cause of failure in closed reduction. CONCLUSIONS: Intervertebral disc injury should be evaluated carefully with MRI and CT in the lower cervical interlocked facet dislocations before trial of reduction or decision makings of treatment.

BACKGROUND: Pathergy, or skin hypersensitivity to needle puncture has been reported as a diagnostic test for Behcets ciisease. But the positivity of pathergy test in recurrent aphthous stomatitis which can be a comporent of Behcets disease is obscure. In recent years it has been noted that the positivity of the test has decreased. It is possible to say that the disposable needles used nowadays are less trauniatic to initiate the reaction than are the nondisposable ones used in the preAIDS ara by some uthors. OBJECTIVE: It is the porpose of this study to clarify the value of pathergy test in differentiating Behcets disease from recurrent aphthous stomatitis and to evaluate the difference of positivity using various kinds of needles, and finally to suggest the most profitable one. METHODS: 34 patients with Behcets disease according to the diagnostic criteria of Shimizu(revisecl) 25 ones in case of applying that of International study group for Behcets disease(ISG) and 21 ones with recurrent aphthous stomatitis, and 25 normal controls were selected. A pathergy test, i.e., intradermal injection of 0.1 ml physiological saline by using 26 gauge & 20 gauge disposable needles and 26 gauge & 20 gauge nondisposable ones were given and the evaluation was made after 24 hours and 48 hours. RESULTS: 1. The positive rates of pathergy test using all kinds of needles in Behcets disease were significantly higher than thoen recurrent aphthous stomatitis and normal controls(p=0.00000-0.03600). The sensitivity were 29.4% 64.7% (Shimizu) and 32.0% 76.0% (ISG), respectively, and the specificity were 91.3%-100.0% for all of them. 2. In Behcets disease, the positive rates of the pathergy test using 26 gauge disposable needles were not significantly different from that of using ZO gauge disposable needles in total and active patients after 24 and 4.3 hours and so were 26 gauge R 20 gauge nondisposable ones(p=0.40134 -0.80603(Shimizu), 0.37551-0.77078(ISG) ). 3. In Behcets disease, the positive rates of pathergy test using 26 gauge nondisposable needles were 59%-68%(Shimiu) and 64% 79% (ISG), which were significantly different, from the test using 20 gauge disposable needles, i.e. 29%-36%(Shimizu), 40%-46%(ISG) in total and active patients(p==0.00753-0.01512) after 24 and 48 hours except for those by the criteria of ISG after 24 hours(p=0.14573-0.15597). CONCLUSION: This study shows that the pathergy test is obviously useful in differentiating Behcets disease from ecurrent aphthous stomatitis and we recommend the intradermal injection of 0.1 ml physiological saline by using 26 gauge nondisposable needle and the evaluation after 48 hours as a standard mithod of pathergy test.

PURPOSE: To report a case of isolated choroidal cystic lesion in the macula with no interval change for two years. CASE SUMMARY: A 29-year-old woman who had suspicious maculopathy was referred to our clinic. Her best corrected visual acuity was 20/20 in the affected right eye, which showed a choroidal cystic lesion on a fundus exam, fluorescein angiography, USG and OCT. The multifocal ERG showed reduced amplitudes of the cystic area in the right eye, and SLO microperimetry revealed reduced retinal sensitivity in the cystic lesion as well as a stable fixation and spared foveal function. There was no evidence of underlying ocular disease in clinical assessment, and the lesion had not undergone interval change for the past two years.

PURPOSE: We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. MATERALS AND METHODS: Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. RESULTS: In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. CONCLUSION: F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.

BACKGROUND: Steroid acne is a folliculitis that can result from a systemic or topical administration of steroid and has been described as showing similar clinical pictures to Malassezia folliculitis, but there have been few reports about the incidence of Malassezia in steroid acne and other acneiform eruptions. OBJECTIVE: Our purpose was to describe the incidences of Malassezia in acneiform eruptions and to discuss about the relationship between clinical steroid acne and Malassezia folliculitis. METHODS: The history, clinical features, direct microscopy, histopathological analysis, and therapeutic results of 125 cases with steroid acne or other acneiform eruptions were described and compared. RESULTS: Over 80% of patients with acneiform eruption receiving systemic steroid revealed significant numbers of Malassezia in the lesional follicle. CONCLUSION: Steroid acne and other acneiform eruptions showing discrete follicular papules and/or pustules localized to the upper trunk or acneiform facial skin lesions associated with multiple acneiform lesions on the body in the summer period should be suspected as Malassezia folliculitis.
