Unsafe abortion is a significant contributor to maternal mortality in Nigeria, and treatment of postabortion complications drains public healthcare resources. Provider estimates of medications, supplies, and staff time spent in 17 public hospitals were used to estimate the per-case and annual costs of postabortion care (PAC) provision in Ogun and Lagos states and the Federal Capital Territory. PAC with treatment of moderate complications (US $112) cost 60% more per case than simple PAC (US $70). In cases needing simple PAC, treatment with dilation and curettage (D&C, US $80) cost 18% more per case than manual vacuum aspiration (US $68). Annually, all public hospitals in these 3 states spend US $807 442 on PAC. This cost could be reduced by shifting service provision to an outpatient basis, allowing service provision by midwives, and abandoning the use of D&C. Availability of safe, legal abortion would further decrease cost and reduce preventable deaths from unsafe abortion.
Cervical cancer is the second most common cancer among Tunisian women, and the incidence rates vary by region. Three Tunisian registries report age-standardized rates of 6.3/105 in the central region, 5.4/105 in the north, and 2.7/105 in the south. High-risk human papillomavirus (HPV) types and their variants differ in carcinogenic potential and geographic distribution. The HPV type and variant distribution could be a factor in the differing rates between regions of Tunisia. Tumor tissue was collected from 142 Tunisian cervical cancer patients. Demographic and reproductive characteristics of the patients were abstracted from cancer registry and hospital records. HPV type and variant analyses were performed using PCR-based Luminex and dot-blot hybridization assays. Eighty-three percent of tumors were infected with at least one HPV type. European variants of HPV16/18 were the most prevalent in tumors from all three regions, with all HPV18 infections and 64% of HPV16 infections being of European lineage. A higher frequency of HPV16 was present in Northern Tunisia (80%) than in Central (68%) or Southern Tunisia (50%) (P = 0.02). HPV18/45 was significantly more common in adenocarcinomas (50%) than in squamous cell carcinomas (11%) (P = 0.004). Frequent infection with European HPV variants most likely reflects the history of European migration to Tunisia. In addition to the importance of understanding the variants of HPV in Tunisia, behavioral and cultural attitudes towards screening and age-specific infection rates should be investigated to aid the development of future vaccination and HPV screening programs and policies.
Cervical cancer disproportionately affects women in developing countries. Cervical cancer is the second most common cancer among Tunisian women, and the cervical cancer incidence rates vary by region. Three Tunisian registries report ASRs of 7.1/105 in the central region, 6.1/105 in the north, and 2.7/105 in the south. High-risk HPV types have genetic variants that differ in both carcinogenic potential and geographic distribution, with aggressive cervical cancers more often reported amongst women infected with HPV16 non-European variants. The HPV type and variant distribution could be a factor in the differing rates between regions. To establish the distribution of HPV types and variants in a cross-sectional study, cervical cancer cases diagnosed in 2007-2008 were identified from the Institut Salah Azaiez in Tunis and from the Central Tunisian Cancer Registry (2002-2007) of the Hôpital Farhat Hached in Sousse. Formalin-fixed paraffin-embedded sections were obtained from case tissue samples for analysis of HPV type and variant using PCR assays. Clinical information was abstracted from the pathology reports and medical records. A geographic location for each case was ascertained using residential information included in medical records. Of the 142 samples collected, 73 cases were from governorates included in the northern registry, 56 from the central registry, and 13 from the southern registry. Preliminary results show 110 cases (77.5%) were infected with at least one HPV type. HPV16 and HPV18 were present in 88.7% and 7.5% of cases infected with a single HPV type, and in 91.8% and 5.9% of squamous cell carcinomas (SCC), respectively. Whereas, HPV18/45 were detected in 33% of adenocarcinomas but in only 7.1% of SCC (p=0.02). Three cases were infected with both HPV16 and HPV18. HPV types 35, 45, 58, 66 and 73 were also identified. All of the HPV18 and 54.7% of HPV16 positive cases were European variants. The distribution of European variants was: 67.9% in the northern, 62.1% in the central, and 66.7% in the southern. Cases infected with a non-European variant of HPV16 had an average age at diagnosis of 53 years, while European infections were later at 55.9 years; although this difference was not significant. There was no difference in distribution of variants by stage of disease. There was no difference in HPV16 variant distribution by histologic type. This is the first study to evaluate HPV variants in Tunisia. Currently approved HPV vaccines will protect against the HPV types most commonly associated with cervical cancer in Tunisia. Although Tunisia is in Africa, frequent infection with European HPV variants most likely reflects the history of European migration both to and from Tunisia. Behavioral and cultural attitudes about screening and age-specific infection rates should be investigated to aid the development of any future vaccination and HPV screening policies.
