Epidemiological and Pathological Aspects of Cervical Cancer in Ivory Coast

Abstract: Cervical cancer is the most common and the leading cause of women death in developing countries. Purpose: To specify the epidemiological and pathological characteristics of cervical cancers in Ivory Coast. Material and methods: This was a retrospective and descriptive study on the cervical cancers histologically confirmed and identified from the registers for recording laboratory of pathological anatomy of Abidjan teaching hospital. The study period was 24 years (January 1984 to December 2007). The parameters analyzed were: frequency, age, sociodemographic status, macroscopic and histological aspects and the prognosis. Results: The cervical cancer represented 78.78% (2064 cases) of gynecological cancers, 42.71% of woman cancer and 17.41% of all cancers. The average age was 48.36 years ranging from 2 to 88 years and a peak incidence between 45-54 years (29%). Multiparity was observed 57.04% (n = 231) and the low socioeconomic level was predominant (70.41%). Concerning pathological examination, the tumor lesions were predominantly budding (51.52%). Squamous cell carcinomas (92.88%) were the most frequent of histological types with 95.1% (n = 1823) of invasive carcinomas. The average age of patients with squamous cell carcinoma was 49 years with 41.5 years for intraepithelial carcinomas and 46.8 years for invasive carcinomas. At the prognosis, squamous cell carcinomas were diagnosed most often in stage pT2 (57.41%) and with extra-cervical represented 66.4% (n = 519). Conclusion: Cervical cancer is the most common cancer in Ivory Coast taking into account male and female together. Its poor prognosis associated with late diagnosis should encourage the establishment of a cytology screening program

An Overview of Neisseria meningitidis

Neisseria meningitidis (the meningococcus) is a member of the normal nasopharyngeal microbiome in healthy individuals, but can cause septicemia and meningitis in susceptible individuals. In this chapter we provide an overview of the disease caused by N. meningitidis and the schemes used to type the meningococcus. We also review the adhesions, virulence factors, and phase variable genes that enable it to successfully colonize the human host. Finally, we outline the history and current status of meningococcal vaccines and highlight the importance of continued molecular investigation of the epidemiology and the structural analysis of the antigens of this pathogen to aid future vaccine development
