STATEMENT OF PROBLEM: Proper finishing and polishing enhance both the esthetics and the longevity of restored teeth. Blade finishing technique would be suited for smoothing and finishing. Evaluation of this technique are necessary. PURPOSE: The purpose of this study was to evaluate the blade finishing and polishing procedures on the surface profile and roughness of ormocer-based composite resin and nanohybrid composite resin. MATERIAL AND METHODS: The material included a ormocer-based composite resin (Admira(R) & Admira(R) Flow); a nanohybrid composite resin (Grandio(R) & Grandio(R) Flow). One hundred forty specimens of each group were prepared using a mylar strip and randomly divied into blade finishing and rubber polishing groups (n=10). The average surface roughness (Ra) in micrometers was measured and the surface profile was examined by scanning electron microscopy (SEM) (Magnification X 200). The data were analyzed by Mann-Whitney Test at 0.05 significance level. CONCLUSION: The results of this study indicated that the mylar strip produced the smoothest surface on all materials and among the finishing-polishing methods was not significanct difference (P>0.05). Ormocer-based flowable composite resin performedthe lowest variability in initial surface roughness among the tested materials.

Behcet disease is a chronic systemic inflammatory disease involving mucous membranes, skin, eyes, gastrointestinal tract, joints, vessels, and neurologic systems. The disease usually manifests in early adulthood. Childhood onset is rare. We experienced a case of Behcet disease in a 11-year-old boy. He suffered from recurrent arthritis of the left knee joint which was managed under the impression of septic arthritis since he was seven years old. Behcet disease should be considered in case of recurrent arthritis mimicing septic arthritis in children.

Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by inappropriate myocardial hypertrophy that occurred in the absence of an obvious cause for the hypertrophy and dynamic left ventricular outflow tract obstruction, caused by asymmetrical septal hypertrophy and systolic anterior motion of the anterior mitral leaflet. The pathophysiological abnormality in HOCM is diastolic dysfunction, abnormal stiffness of the left ventricle with resultant impaired ventricular filling and impaired vasodilator reserve (perhaps related to the thickened and narrowed small intramural coronary arteries found in HOCM). During the early course of this progressive disease, treatment consists of negative inotropic drugs. Surgery has been the only therapeutic option in patients with hypertrophic cardiomyopathy who are resistant to drug treatment and sequential pacemaker therapy. We describe a novel catheter-based technique that may replace surgical myocardial reduction. The technique is interventional infarction of a portion of the interventricular septum by the infusion of alcohol into a selectively catheterized septal artery.

Compartment syndrome is rarely associated with non-traumatic rhabdomyolysis. We report the case of a 23-year-old man who developed compartment syndrome associated with rhabdomyolysis caused by prolonged immobilization after antidepressive drug overdose. Elevation of serum creatine phosphokinase and myoglobinuria indicated rhabdomyolysis. Painful swelling of the right buttock and thigh and right lower limb paralysis with sensory and motor deficit were suggestive of gluteal and thigh compartment syndrome with the complication of sciatic nerve injury. The patient received an immediate fasciotomy, medical treatment and rehabilitation. At five months after initial treatment, the patient could walk independently with nearly full recovery of his right lower limb function.
