BACKGROUND: Aspiration pneumonia remains a serious result associated with general anesthesia. Therefore, we studied the effectiveness of preanesthetic ranitidine in increasing gastric pH to prevent aspiration pneumonia. METHODS: Eighty patients scheduled for elective surgery were randomly divided into four groups with twenty patients in each group. Patients in control group were not given preanesthetic ranitidine; patients in group I received 300 mg of ranitidine orally at night before surgery, patients in group II received 150 mg of ranitidine orally both the night before surgery and one hour before surgery respecvtively and patients in group III recieved 150mg of ranitidine orally one hour before surgery. RESULTS: Compared with control group, the mean gastric pH of preanesthesia and 1 hour after anesthetic induction increased significantly in the group I, II, III (P<0.0001). There was significant increased gastric pH in the group II compared with group I and III. CONCLUSIONS: These results demonstrate that ranitidine markedly increase the gastric pH. So, we recommend that patients receiving general anesthesia would be taken Hz-antagonist such as ranitidine preoperatively.

Acute osteomyelitis after the contusion is a rare clinical entity. The complications of contusion are large hematoma formation, compartment syndrome, myositis ossificans and acute osteomyelitis. Authors experienced an acute osteomyelitis in the shaft of the radius after contusion of the forearm and report this case with references.

We report the surgical endodontic treatment of a maxillary first premolar with a lateral lesion that originated from an accessory canal. Although lesions originating from accessory canals frequently heal with simple conventional endodontic therapy, some lesions may need additional and different treatment. In the present case, conventional root canal retreatment led to incomplete healing with the need for further treatment (i.e., surgery). Surgical endodontic management with a fast-setting calcium silicate cement was performed on the accessory canal using a dental operating microscope. At the patient's 9-month recall visit, the lesion was resolved upon radiography.

Fabry's disease is a rare, inborn error, sex-linked disorder of glycosphingolipid metabolism with death occurring from myocardial or renal involvement at 4th or 5th decades. The primary metabolic defect lies in the deficient tissue activity of the enzyme alpha-galactosidase A which results in progressive accumulation of the specific neutral glycosphingolipids, cerebroside dihexoside(CDH) and cerebroside triihexoside(CTH), within the lysosomes of endothelial, perithelial and smooth muscle cells of the cardiovascular and renal systems predominantly. Clinical manifestations are sequelae of the anatomic and physiologic alterations produced by the progressive deposition of glycosphingolipid in the tissues. We report the first case of successful renal transplantation in a patient with Fabry's disease in Korea. The patient was a 33-year-old male. Fabry's disease was confirmed by measurement of serum alpha- galactosidase level and renal biopsy. Biopsy finding showed lamellar inclusion bodies on electron microscopy. Galactosidase activity was also markedly decreased. He has been well for 49 months.

Although fiber-reinforced posts have been widely used, they sometimes fail to obtain sufficient retention because of an extremely large canal space. To address this, several techniques have been introduced including relining of the fiber-reinforced posts. Here, we used a relined glass-fiber post to increase retention and fitness to the root canal in a crown reattachment case. The relining procedure was performed by using an indirect method on the working cast. This case also highlights the esthetic concerns regarding dehydration of the attached crown fragment.

The purpose of this study was to compare the effect of surface sealing materials on microleakage and surface roughness in Class V composite restorations. Twenty five standardized Class V cavity preparations were made on the facial surface of human premolars and were randomly assigned to 5 groups. The teeth were restored with Z-250 after applying Single Bond. Following 7 days storage in distilled water at 37degrees C, the restorations were sealed as following systems : No sealing ; Single Bond Adhesive ; Biscover ; Fortify ; Optiguard. Then, toothbrush abrasion test was conducted using a wear testing machine. Surface roughness was measured by means of profilometer before and after toothbrushing and the results were statistically analysed by using a paired t-test and ANOVA. The bonded interfaces and the changes of surface roughness were examined by SEM. For microleakage test, specimens were stained in a 2% methylene blue solution, then longitudinally sectioned and analyzed for leakage at occlusal and cervical interfaces using stereomicroscope. The results were statistically analysed by using a Kruskal-Wallis and Mann-Whitney U test. Surface roughness was increasing in all groups after toothbrushing, but no statistically significant differences. In SEM observation, surface sealant was partially retained and partially detached in bonded interfaces. Especially, microgap was identified in cervical margins. In microleakage test, there was better seal in the enamel region and a significant difference between groups at occlusal margin. Control group and Single Bond group had significantly better marginal seal at enamel margin than cervical margin.
