Nasopharyngeal cancer or nasopharyngeal carcinoma (NPC) is the most common cancer originating in the nasopharynx. The factors that induce nasopharyngeal cancer are still not clear. Additional information about the chemicals or genes related to nasopharyngeal cancer will promote a better understanding of the pathogenesis of this cancer and the factors that induce it. Thus, a computational method...

OBJECTIVE To compare the thickness and organization of surface epithelium, and high endothelial venules in subepithelial compartments of human nasopharyngeal and palatine tonsils, with reference to functional differences. STUDY DESIGN Comparative cross-sectional. PLACE AND DURATION OF STUDY The Anatomy Department of CPSP Regional Centre, Islamabad, from January to December 2005. METHODOLO...

background pertussis is a respiratory and contagious disease which is mostly caused by bordetella pertussis and b. parapertussis. it usually spreads from person to personduring the incubation or catarrhal phase of the disease. despite of large-scale vaccination, whooping cough is still an endemic disease with several outbreaks. objectives the aim of this study was to determine the prevalence of...

BACKGROUND To investigate patterns of failure and survival rates of elective irradiation of upper neck in N0 nasopharyngeal carcinoma patients. METHODS From February 1996 to November 2002, 97 patients without cervical lymph node involvement were admitted for radiotherapy alone. Before treatment, each patient underwent enhanced CT of nasopharynx and neck. All patients received radiotherapy to ...

BACKGROUND Early identification and control of pathogenic bacteria are important in the treatment of pneumonia. Currently, two rapid antigen detection kits for pneumococcal pneumonia are available: one uses urine samples and the other, named RAPIRUN® S. pneumoniae, uses sputum samples. RAPIRUN® has shown high sensitivity with nasopharyngeal swab samples from pediatric patients. In this study, w...

BACKGROUND Previous studies have shown that Epstein-Barr virus (EBV)-encoded latent membrane protein 1 (LMP1) is closely associated with the occurrence and development of nasopharyngeal carcinoma, and can be used as a tumor marker in screening for the disease. Here we report a new methodology based on highly specific and sensitive surface-enhanced Raman scattering (SERS) technology to detect LM...

The diagnosis of postradiation nasopharyngeal skull base lesions in petients with nasopharyngeal carcinoma (NPC) is still a tough problem in clinical practice. An early and accurate diagnosis is important for subsequent management. We prospectively evaluated the diagnostic value of plasma Epstein-Barr virus(EBV) DNA in detecting postradiation nasopharyngeal skull base lesions in NPC patients. F...

OBJECTIVES The aim of this case-control study was to evaluate the nasopharyngeal pH (NasopH) in children with normal or abnormal pH-metry in two groups of patients; 1) children presenting gastroenterological symptoms; and 2) children with chronic respiratory symptoms. METHODS From February 2004 to January 2005, all consecutive patients referred for 24-hour pH-metry and in whom gastroesophagea...
