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.

AIM: To compare the use of the instruments' built-in normative databases, the sensitivities of time-domain optical coherence tomography (Stratus OCT) and spectral-domain OCT(Spectralis OCT) in the detection of retinal nerve fiber layer (RNFL) defects in patients with glaucoma. METHODS: Fifty-two eyes of 35 patients with open angle glaucoma were included. A total of 69 hemiretinas with photographically identified RFNL defects were analyzed using the fast RNFL scan of Stratus OCT and the circle scan in Spectralis OCT. The OCT parameters were evaluated at 5% and 1% abnormality levels using the instruments' built-in normative databases. The diagnostic sensitivity of each parameter was compared between the two devices. RESULTS: The Spectralis OCT detected RNFL defects within each quadrant more frequently than the Stratus OCT at both the 5% (79 7% vs 63 8%,P=0 01) and 1% (56 5% vs 40 6%, P = 0 01) abnormality levels. At the 1% abnormality level,the sensitivity was significantly higher in the standard sector of Spectralis OCT than in the clock-hour sector of the Stratus OCT(68 1% vs 39 1%,P<0 01). CONCLUSIONS: Using the instruments' built - in normative databases, the diagnostic sensitivity of the Spectralis OCT parameters was higher than that of the Stratus OCT parameters for detecting glaucomatous RNFL defects.

The anterior discectomy is widely accepted method for removal of the herniated disc material of cervical spine due to direct visualization of the lesion site. In addition, it is believed to prevent recurrence of herniation, progression of degenerative change, and to preserve normal cervical lordosis after the fusion. For more effective anterior fusion and early postoperative ambulation without prolonged external support, internal fixation technique was introducsuspected to influence the result of operation, the type of bone graft and age of the patient may be the effective factors to the late result. ed. Authors reviewed 36 patients with cervical disc herniation and evaluated the result of anteior discectomy and fusion with plate fixation. With a mean follow up of 34 months, there were remarkable symptomatic improvement at most instances and bony union in situ within 3 months in all cases after the operation. Disclosed complications were 2 cases of hoarseness which was improved spontaneously, and 1 case of dysphagia. At the comparison of the effect of the factors which were suspected to influence the result of operation , the type of bone graft and age of the patient may be the effective factors to the late result.

Percutaneous transluminal angioplasty(PTA) were performed in three patients with atherosclerotic stenosis of subclavian arteries. The arteries were successfully dilated without complications during the procedure. All patients were asymptomatic during follow-up periods ranging from eight months to fifteen months after PTA.

A 26-year-old Korean man had an erythematous scaly plaque on his right thigh for fifteen years. He was diagnosed with chronic eczema and treated with topical steroid, but no clinical improvement was obtained for 15 years. Laboratory studies including complete blood cell count, urinalysis, liver and renal function test, and peripheral blood smear were normal. A biopsy specimen showed hyperkeratosis, acanthosis, and mononuclear cellular infiltration in the epidermis. These cells had a perinuclear halo and showed a Pautrier's microabscess like configuration. In the dermis, there was a band like infiltration of inflammatory cells. Infiltrates of the epidermis were negative for leukocyte common antigen(CD45) and positive for Pan T cell(CD45RO). He was treated with topical PUVA twice a week for twelve weeks. Clinical and pathological improvements were obtained. We propose PUVA may be a useful therapeutic modality to treat Woringer Kolopp disease.
