STATEMENT OF PROBLEM: Although zirconium oxide ceramics are more and more commonly used in restorative dentistry, for many clinical applications only limited data can be found in the literature. However, it is quite clear that hydrofluoric acid etching is impossible with zirconia ceramics. Therefore, other bonding techniques are required in order to lute these materials adhesively. PURPOSE: The purpose of this study was to evaluate the effects of surface treatments on shear bond strengths between two resin cements and a zirconia ceramic. MATERIALS AND METHODS: Experimental industrially manufactured yttrium-oxide-partially-stabilized zirconia ceramic discs (Adens, Korea) were used for this study. The ceramic specimens divided into five experimental groups and a control group (as received). Five surface treatments were studied. 1) sandblasting with 110 micrometer Al2O3 at 3 bars pressure 13 seconds at a distance of 10mm, 2) flame-treated with the Silano-Pen for 5 s/cm2, 3) grinding with a diamond bur, 4) sandblasting + Silano-Pen treatment, 5) diamond bur preparation+ Silano-Pen treatment. Acrylic plastic tube (5 mm in height and 3 mm in diameter) were filled with composite to fabricate composite cylinders. The composite cylinders were bonded to the ceramic specimens with either Superbond C & B or Panavia F resin luting agents. All cemented specimens were tested under shear loading until fracture on universal testing machine at a crosshead speed 1mm/min, the maximum load at fracture was recorded. Shear bond strength data were analyzed with oneway analysis of variance and Tukey HSD tests (p<.05). Treated ceramic surfaces and fracture surfaces after shear testing were examined morphologically using scanning electron microscope. Results: Ceramic surface treatment with Silano-Pen after sandblasting improved the bond strength of Superbond C & B resin cement. Superbond CandB resin cement at Silano-Pen after sandblasting(27.4 +/- 3.8 MPa) showed statistically higher shear bond strength than the others. CONCLUSION: Within the limitation of this study, Superbond C & B resin cement are suitable for cementation of zirconia ceramics and flame-treated with the Silano-Pen after sandblasting is required to enhance the bond strength.

We reported a case of huge cystic trigeminal neurinoma. The patient was 35 year old female with trigeminal nerve dysfunction and hemiparesis. The computed tomography disclosed a huge cystic low density mass at the temporal base and suprasellar cistern that extended to cerebellopontine cistern through the tentorium, and enlargement of Meckel's cave on coronal scan. Through the infratemporal and retromastoid suboccipital approach, the cystic content was aspirated and cyst wall was removed. The cystic change of neurinoma may be due to mucoid degeneration and liquifaction.

Duodenal choriocarcinoma, either primary or metastatic, is very rare. Early diagnosis and prompt initiation of chemotherapy improve the prognosis of this neoplasm. We herein present, together with the referred literatures, a case of a 47-year-old female patient who visited to our hospital with upper intestinal bleeding. She was diagnosed as duodenal choriocarcinoma by operation. Brain metastasis was found soon after the operation and combination chemotherapy was done.

Ulcerative colitis produces repeated improvements and relapses of chronic colonic inflammation. Complications of the disease can include bleeding, toxic megacolon, colon cancer, or colon stricture. While colonic strictures are common in Crohn's disease, this complication rarely appears in ulcerative colitis cases. Unlike in Crohn's disease, where strictures are commonly treated by endoscopic balloon dilatation, surgical management is the basis for treatment of strictures in ulcerative colitis because malignant strictures are common and because the stricture region is generally wide. We report the case of a patient who presented with decreased stool caliber while undergoing treatment for ulcerative colitis. We performed therapeutic balloon dilatation in this patient with a benign stricture caused by ulcerative colitis and experienced improvement of symptoms.

Argon Plasma Coagulation (APC), a new endoscopic hemostatic method of non-contact electrocoagulation, is widely used for ablation of Barrett's esophagus, residual tissue after polypectomy, palliation of malignancy and hemostasis of radiation proctopathy, bleeding peptic ulcers, prevention of esophageal varices. Although a safe and effective procedure, if used inappropriately, side effects such as failure of hemostasis, perforation, asymptomatic submucosal emphysema, and pneumoperitoneum can occur. Perforations progressing to peritonitis require surgery, but a pneumoperitoneum can recover with conservative treatment. Therefore, clinicians should distinguish these two different cases. There are no domestic cases of asymptomatic pneumoperitoneum caused by APC. In two cases treated by endoscopic submucosal dissection of polypectomy and early gastric cancer, asymptomatic pneumoperitoneum occurred after argon plasma coagulation treatment. We present these two cases of asymptomatic pneumoperitoneum treated successfully by conservative treatment without complications.

Lymphangioma is a benign vascular lesion that shows the characteristics of subepithelial tumor, which can proliferate in the lymphatic system. Only a few cases of multiple lymphangimas of the colon, the so called "colonic lymphanigomatosis", have been currently reported on the medical literature. Because lymphangioma is absolutely a benign tumor, it does not require any specific treatment, except for rare disease-related symptoms or complications such as anemia, intussusception and protein-losing enteropathy. Endoscopic resection for this tumor has sometimes been performed for both diagnostic and therapeutic purposes. We recently experienced a case of multiple colonic lymphangomas that arose in the ascending colon of a 46-year-old male patient and these lesions were found during performance of colonoscopy. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via endoscopic resection. Follow-up colonoscopy at 1 year after the initial examination showed complete resolution of the previously noted lesions without any specific treatment. We report here on a very rare case of colonic lymphangiomatosis along with a brief review of the relevant literature.

Mirizzi syndrome is commonly defined as a common hepatic duct obstruction caused by extrinsic compression from an impacted stone in the cystic duct. Mirizzi syndrome has traditionally been treated surgically. However, there are several case reports and small series describing endoscopic and percutaneous alternatives to open surgery. We encountered two cases of type I Mirizzi syndrome that was successfully treated endoscopically. We report these cases with a review of the relevant literature.
