epidemiological study on survival of oropharyngeal cancer cases in Alexandria, Egypt

A retrospective cohort study was conducted to determine the 5-year survival and prognostic factors for survival for 407 oropharyngeal cancer cases registered in the 3 main hospitals in Alexandria, Egypt, from 1996-2000. Survival analysis was conducted using Kaplan-Meier curves, and multivariate Cox regression analysis. The overall 5-year survival rate was 30.8%. Multivariate analysis showed that significant prognostic factors for survival were tumour stage [hazard ratio = 2.39; 95% CI: 1.41-11.72], tumour site and patient's age. Secondary prevention of oral cancers can be conducted through examination of the oral cavity to find precancerous and early cancerous lesions and hence improve survival

Towards polio eradication in Alexandria

The purpose of this study was to enhance the ongoing activities in Alexandria towards polio eradication via: surveillance through early detection of acute flaccid paralysis [AFP] cases and providing epidemiological assistance in follow up and case classification. During the period December 1994 through November 1995, the following activities were performed: arranging seminars and scientific meetings, activating the role of private sector in AFP surveillance, using mass media to encourage active participation of the community through a TV spot announcement; augmenting surveillance of new cases of AFP and control measures, participation in national days of immunization, and arranging outreach programmes to vaccinate high risk groups. During the study period 15 AFP cases were detected giving a rate of 1.06 per 100,000 children below 15 years and 3.5 per 100,000 children below 5 years of age. Follow up showed that 5 cases were confirmed poliomyelitis. Three of the confirmed cases were from East district. Three confirmed cases occurred during the summer months. All confirmed cases were fully vaccinated. One confirmed case died 45 days after onset of AFP. Four confirmed cases were suffering from residual paralysis after 60 days from onset. It was concluded that continued strengthening of the expanded programme on immunization within the context of primary health care and by improving current poliomyelitis vaccines, clinical and laboratory surveillance are essential to reach the goal of poliomyelitis eradication
