ABSTRACT
This case report describes the immediate loading of narrow diameter implants in the mandibular incisor area using full-digital flow. The 3-dimensional position of the implants was planned using digital software, and the corresponding surgical template was fabricated. The implants were inserted immediately after extraction and on the same day, the interim abutment and bridge were placed. At 8 weeks after surgery, the stability of the implants was measured and a digital impression was made using a scan body. Customized titanium abutments and a cementtype full zirconia bridge were delivered. At 36 weeks’ follow-up, no clinical or radiographic complications were detected, and the patient was satisfied with the results.
ABSTRACT
Hypopharyngeal cancers are often diagnosed at an advanced stage and have a poor prognosis. Even when they are diagnosed at an operable stage, surgery often results in substantial morbidity and decreased patients' quality of life. Although the endoscopic diagnosis of early hypopharyngeal cancer is difficult, recent developments in advanced imaging endoscopy have enabled easier diagnosis of these lesions. Endoscopic resection of early hypopharyngeal cancer is a potential minimally invasive treatment that can preserve the function and quality of life of patients. Reports of this procedure are limited, however. We report a case of hypopharygeal cancer treated with endoscopic resection.

BACKGROUND/AIMS: Photodynamic therapy (PDT) has a promising effect on nonresectable cholangiocarcinoma (CC) but its long term data is not yet available. This study examined the long term outcome and factors associated with increased survival after performing PDT for hilar cholangiocarcinoma. METHODS: A list of 393 patients with a diagnosis of hilar CC was retrieved from the database of Soonchunhyang University Hospital (Seoul, Korea) and these patients were seen from January 1, 2001, to April 1, 2010. We retrospectively reviewed the records of 74 patients who underwent PDT in addition to biliary stenting with/without chemoradiation. RESULTS: The median overall survival from the date of diagnosis to death or to the last follow-up was 11.7 months (range: 2.2~78.4). After performing PDT, a complete remission was observed in 1.3% (1/74) of the patients who had a superficial depth of tumor without lymph node involvement. On multivariate analysis using the Cox regression model, increasing the time to treatment after the diagnosis was a statistically significant predictor of shorter survival after PDT [Odds ratio: 3.25, 95% confidence interval (CI): 1.90~4.71, p=0.034]. CONCLUSIONS: Although PDT does not prevent progression of CC, it appears to control the cholestasis. The early treatment of PDT after the diagnosis showed a survival benefit for patients with advanced hilar CC.
