In connective tissue diseases, autoantibodies cause pulmonary interstitial inflammation and fibrosis, and patients require treatment with an immunosuppressive agent such as a steroid. Dermatomyositis is an incurable, uncommon form of connective tissue disease that occasionally causes diffuse pulmonary inflammation leading to acute severe respiratory failure. In such cases, the prognosis is very poor despite treatment with high-dose steroid. In the present case, a 46-year-old man was admitted to our hospital with dyspnea. He was diagnosed with dermatomyositis combined with cryptogenic organizing pneumonia (COP) with respiratory failure and underwent treatment with steroid and an immunosuppressive agent, but the COP was not improved. However, the respiratory failure did improve after treatment with intravenous immunoglobulin, which therefore can be considered a treatment option in cases where steroids and immunosuppressive agents are ineffective.

STATEMENT OF PROBLEM: One of the common problems of dental implant prosthesis is the loosening of the screw that connects each component, and this problem is more common in single implant-supported prostheses with external connection, and in molars. PURPOSE: The purposes of this study were: (1) to compare the initial abutment screw detorque values of the six different implant-abutment interface designs, (2) to compare the detorque values of the six different implant-abutment interface designs after cyclic loading, (3) to compare the detorque values of regular and wide diameter implants and (4) to compare the initial detorque values with the detorque values after cyclic loading. MATERIAL AND METHODS: Six different implant-abutment connection systems were used. The cement retained abutment and titanium screw of each system were assembled and tightened to 32Ncmwith digital torque gauge. After 10 minutes, initial detorque values were measured. The custom titanium crown were cemented temporarily and a cyclic sine curve load(20 to 320N, 14Hz) was applied. The detorque values were measured after cyclic loading of one million times by loading machine. One-way ANOVA test, scheffe's test and Mann-Whitney U test were used. RESULTS: The results were as follows : 1. The initial detorque values of six different implant-abutment connections were not significantly different(p> 0.05). 2. The detorque values after one million dynamic cyclic loading were significantly different (p <0.05). 3. The SS-II regular and wide implant both recorded the higher detorque values than other groups after cyclic loading(p <0.05). 4. Of the wide implants, the initial detorque values of Avana Self Tapping Implant, MIS and Tapered Screw Vent, and the detorque values of MIS implant after cyclic loading were higher than their regular counterparts(p <0.05). 5. After cyclic loading, SS-II regular and wide implants showed higher detorque values than before(p <0.05).

STUDY DESIGN: Clinical and radiographic results of spine fracutre treated with pedicle screws and hooks were reviewed. OBJECTIVES: Evaluate the efficacy of tile pedicle screw and hook for thoracolumar bursting fracture. SUMMARY OF LITERATURE REVIEW: Despite of the mechanical advantage of the pedicle screw, the metal failure in short segment fusion has been reported. A biomechanical study showed additional laminar hook increased rotational strength. MATERIALS AND METHODS: Between 1994 and 1996, seventeen patients who had a Denis type B bursting fracture of the thoracolumbar spine were treated by posterior instrumentation with pedicle screws and laminar hooks and auterior interbody fusion after partial corpectomy. They have been followed for an average of 13.4 months. RESULTS: At last follow-up, radiographs showed successful fusion of the injured spinal segment in all patient. The subsidence of grafts which were used In anterior interbody fusion was an average of 0.76mm. There was a loss of 2.6 degrees on average in the correction of the kyphosis. No patients had screw breakage or loosening. CONCLUSIONS: We concluded that posterior fixation with screws and hooks, anterior decompression by partial corpectomy, and strut-grafting in patient who had a Denis type B bursting frafture of the thoracolumbar spine yielded good radiographic and functional results.

OBJECTIVE: The purpose of this study is to report the technical feasibility and the result of one stage operation for the bursting fracture of the thoracolumbar spine by posterior approach. METHODS: Seven patients underwent corpectomy and replaced the space with titanium mesh cage filled up with autologous bone pieces through unilateral posterior route after removal of the facet joint and the pedicle followed by pedicle screw fixation at the same surgical field. RESULTS: All patients tolerated the procedures well except one patient complicated with air embolism. Postoperative radiographs showed effective decompression and well placed instruments. Preoperative neurological deficits disappeared completely in two patients but some deficits persisted in the remainders. In two patients, epidural venous bleeding was troublesome and he needed transfusion of 5 pints of packed red blood cell. And another patient complicated with air embolism during operation was recovered with impunity after operation. To insert the mesh cage through the narrow corridor posterolaterally, it was unavoidable to sacrifice one spinal root. CONCLUSION: In spite of technical difficulty, one stage spondylodesis for the bursting thoracolumbar spine though unilateral posterior approach seem to be an effective operative procedure.

BACKGROUND: The decision to administer oral anticoagulation therapy depends on accurate assessment of stroke risk in patients with atrial fibrillation (AF). Various stroke risk stratification schemes have been developed to help inform clinical decision making. The CHADS2 and CHA2DS2-VASc scores have been used in estimating the risk of stroke in patients with AF. Recently R2CHA2DS2-VASc score was developed. The objective of the current study is to validate the usefulness of the R2CHA2DS2-VASc score and to compare the accuracy of the CHADS2, CHA2DS2-VASc, and R2CHA2DS2-VASc scores in predicting a patient's risk of stroke. METHODS: Based on medical records, we conducted a retrospective study of patients hospitalized with AF from March 2011 to July 2013. A total of 448 AF patients were included in this study. The receiver operating characteristic (ROC) curve analysis in MedCalc was used for comparison with respective diagnostic values. RESULTS: The patient characteristics showed male predominance (60.9%). Among the 448 AF patients, 131 (29.2%) patients had strokes during the study. A R2CHA2DS2-VASc score of more than 5 is the optimal cut-off value for prediction of stroke. A risk score of three, the area under the ROC curve (AUC) of R2CHA2DS2-VASc score (AUC 0.631; 95% confidence interval, 0.585-0.679) was the highest. A significant difference was observed between AUC for R2CHA2DS2-VASc, CHADS2, and CHA2DS2-VASc scores, but no meaningful difference between CHADS2 and CHA2DS2-VASc scores. CONCLUSION: We determined the usefulness of the R2CHA2DS2-VASc score, which showed better association with stroke than the CHADS2 and CHA2DS2-VASc scores.

Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer's ring. Among the Waldeyer's ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.
