Background and Objectives:Helicobacter pylori infection is strongly associated with chronic gastritis and ulcer disease and mucosa-asociated lymphoid tissue (MALT) and represent an extragastric reservoir for H. pylori infection. This study was designed to find out the settling frequency of H. pylori in tonsil and adenoid tissues by Compylobacter like organism (CLO) test on tonsilectomy and adenoidectomy specimens in Koreans. Materials and Method:We reviewed the records of 52 patients aged 3 to 51 who had undergone an adenoidectomy, tonsillectomy, or adenotonsillectomy procedure under local or general CLO test kit. Color changes were noted after 20 minutes and after periods of 1, 3, and 24 hours. Results:Thirty three (63.5%) of the 52 patients were shown to be H. pylori positive. H. pylori positive rate was not significantly different acording to operation methods, age and sex. H. pylori positive rate in tonsil specimens (62.7%) was significantly higher than that in adenoid specimens (17.6%)(p<0.05). Conclusion: H. pylori infection. Tonsillectomy may be associated with decreased prevalence of H. pylori colonization. Further study is needed about corelation betwen H. pylori colonization in tonsil and H. pylori associated gastric disease. (Korean J Otolaryngol 2003 ;46 :846-50)

Glomus tumor, a benign tumor arising from the glomus body, usually occurs in the soft tissue of the extremities, particularly in the subungal region of the fingers. As a tumor, it is relatively rare in the head and neck region and even rarer in the nasal cavity. We have experienced a glomus tumor originated in posterior portion of nasal septum. A 82-year-old male presented a left nasal cavity mass associated with intermittent nasal obstruction and epistaxis, for which endoscopic excision with bipolar electrocautery was performed. Histopathologic findings led to the diagnosis of a glomus tumor, which originated from posterior septal artery. There was no evidence of recurrence after 6 months from the operation. We report this case with a review of literature. (Korean J Otolaryngol 2006;49:221-4)

통신망이 ISDN으로 진화되어감에 따라 전송분야에서 요구되어지는 새로운 기술 및 기능에 대하여 고찰하였다. 단기적으로는 디지틀 가입자 전송 및 64kbps 완전채널 기능, 장기적으로는 회선의 분기/분배 기능, 광가입자 관련기술 및 광대역 비동기식 다중기능 등이 요구될 것으로 전망된다.

Prior to the national narrowband ISDN commercial service, it is necessary to develop the wideband switching capability in order to prepare the needs for wideband services which are expected to increase rapidly in the near future. Among the wideband channels, HO channel switching is expected to be implemented based on the present narrowband ISDN switch. In the development of HO channel switching, both of circuit switched mode and packet switched mode must be implemented like narrowband case. In this paper, an implementation scheme of wideband switching function on the existing TDX-lB/ISDN switch based on the circuit switched mode is suggested. For this, we proposed multi-time slot assignment method using divided in two channel table and addition of dedicated wideband switch method which utilizes existing switch module. We also surveyed the applicability of the two methods to the TDX-1B/ISDN switch. Based on this survey, we finally proposed a implementation scheme adopting the two methods par tially.

Background and Objectives: The periorbita has been regarded as the crucial structure in decision of orbital exenteration in the patients with paranasal malignancies. The mass beyond the thickened periorbita on T2-weighted images was considered to be a positive finding of orbital invasion. The purpose of this study is to evaluate the oncological safety of endoscopic removal of infiltrated tumor onto the periorbita but not transgress into orbital fat. Patients and Methods: Five patients of advanced maxillary cancer, showing bony orbital wall destruction and infiltration onto the periorbita but not transgress into orbital fat, underwent partial or total maxillectomy. Preoperative Cl and MRI were performed in all cases and compared with intraoperative findings. The successful dissection between tumors and periorbita using bipolar nasal coagulation forceps and tumor forcep was performed under endoscopy. Results: The mean age was 54.4 (41-74) years. All tumors of five patients originated from maxillary sinus and extended to involve multiple different subsites according to AJCC (2002, 6^(th) ed.) Histopathology included four squamous cell carcinomas and one adenoid cystic carcinoma. Follow-up ranged from 30 to 121 months (mean 53.6 months). All cases showed no local recurrence on the periobita after endoscopic removal. One patient had local recurrence in the pterygopalatine fossa and the other had in the neck. Conclusion: Endoscopic removal of infiltrated tumor onto the periorbita using microdebrider, bipolar nasal coagulation forceps and tumor forceps can be oncologically safe technique in advanced maxillary cancer infiltrated onto the periorbita but not invaded into orbital fat.
