Between August 2003 and April 2005, 112 patients with Stage I-IVB nasopharyngeal carcinoma treated by intensity-modulated radiation therapy were included. Measurement of the primary tumor volume was based on contrast-enhanced computed tomography scans before treatment. A receiver operating characteristics curve was use... |
RESULTS |
The mean primary tumor volume for 112 patients with nasopharyngeal carcinoma was 33.9 ± 28.7 ml. Within the framework of UICC T-staging, all patients were divided into four groups according to the primary tumor volume. We call it the volume stage (V1 <15.65 ml, V2 = 15.65-24.25 ml, V3 = 24.25-50.55 ml and V4 >50.55 ml)... |
CONCLUSIONS |
This study demonstrated that the primary tumor volume had significantly impacted on the prognosis of patients with nasopharyngeal carcinoma. We proposed that the primary tumor volume should be considered as an additional stage indicator in the new revision of the clinical stage of nasopharyngeal carcinoma.Dihydroartemi... |

Background: Hepatitis B is a silent epidemic. The Hepatitis B virus has only human reservoir. Dental professionals are at an increased risk of contracting this highly infectious disease due to the nature of their work. |
Aim: To assess the knowledge, attitudes and practices of first year, second year, third year, fourth year BDS students, dental interns, practicing dentists and the dental auxiliaries about Hepatitis B infection. |
Materials and methods: A pre-tested, self-administered cross-sectional survey containing 16 questions about various aspects of Hepatitis B was conducted among 354 subjects. |
Statistical analysis: Descriptive statistics were carried out and statistical tools such as Chi-square test and contingency coefficient (CC) were employed. A P-value of less than 0.05 was considered statistically significant. All P-values were two tailed. |
Results: The response rate was 100% (n=354). Majority of the dental professionals were aware of the hepatitis B infection and transmission. Their knowledge about the vaccination schedule and post exposure prophylaxis was lower. The dental auxiliaries showed a very know level of knowledge and awareness in all the questi... |
Conclusion: Overall good awareness level in the professionals studied but a less than satisfactory level in the auxiliary workers. Amongst the professionals, the first and second year students showed a relatively lower level of awareness. |
