The majority of noma patients surviving with aesthetical effects are exposed to stigmatization and social rejection. Studies focusing on the socio-psychological impact of noma survivors have rarely been done. Our study aimed to identify the differences in social acceptance/rejection and the influencing factors associated with social acceptance in noma patients. Methods: A cross-sectional study was conducted at the NGO-Sentinelles (Niger) reception center on patients with noma from Zinder, Maradi, and Tahoua regions between 9<sup>th</sup> May 2017 and 2<sup>nd</sup> June 2017. The survey was conducted through a face-to-face interview on patients admitted to the center and those discharged from the centre after the treatment. The interview questionnaire comprised 45 questions (Cronbach’s alpha coefficient = 0.812) with pathological information, sociodemographic characteristics, and socio-psychological qualitative information. Findings: We recorded 50 noma patients (43 from Zinder and 7 from Maradi and Tahoua). The younger patients (1 - 5 years old), noma patients who stayed in school during follow-up treatment, patients who were referred by a health structure, patients enrolled into the centre in a short time (<30 days), and patients in the acute phase of noma had a significantly high social acceptance rate with 60.0%, 82.9%, 60.0%, 57.1% and 94.3% respectively;whereas single adults and cheek lesion site had the highest social rejection rate when compared to their corresponding factors with 60.0% and 86.7% respectively. There were significant differences in victims’ perception of noma [χ<sup>2</sup> = 45.536, (P < 0.001)] and acceptance of their new faces [P = 0.023], between the social acceptance and social rejection rate, therefore all patients who accepted their new faces felt social acceptance. Social acceptance was significantly highly correlated with pathological history (admission method, phase of noma, care, and treatment received at center) with r<sub>s</sub> ranging from 0.609 to 0.810, moderately correlated with patient’s sociodemographic characteristics (age, marital status, and region) with r<sub>s</sub> ranging from 0.381 to 0.474. Lowly correlated with clinical evolution after treatment (r<sub>s</sub> = 0.293). Logistic regression results showed that the likelihood of social acceptance increased when the patient’s age was young (≤15 years), their marital status was minor, they were enrolled at the school before noma appearance, they were referred to the centre after diagnosis, the admission time to the centre was short (≤30 days), acute phase of noma, and care received at the centre was non-surgery. The location of the lesion on the cheek was a risk factor for social acceptance, indicating cheek lesions from noma increased the likelihood of social rejection in our study. Conclusion: The sociodemographic characteristics, pathological history, and psychological aspects of noma patients were correlated and were found to be important factors influencing their social acceptance/rejection rate.展开更多

This study aimed to assess alternative, acceptable, affordable sanitation disposal and practices for groundwater quality rehabilitation in the cities of Cotonou and Lomé. The study was based on the participatory transdisciplinary approach, field surveys, feedback from interactions with stakeholders, experiences of the practitioners and institutional consultations. This multi-stakeholder approach helped to appreciate ecological aspects of sanitation disposal and its implications on water quality improvement. SWOT model was used to analyze the relevance of assessed ecological system. Well water quality is deteriorated by traditional waste management disposal. Ecological sanitation systems are septic tanks on polyethylene, above-ground latrines and phytoremediation technique in the swamp areas. Collected wastes are used for composting and biogas production. Based on the optimist scenario at 2030 horizon, kind success factors of groundwater security are participation of citizens, existence of sanitation market, valorization of the waste by category, low-cost disposal adaptable to the individual, household and neighborhood’s scales. The strategic directions rely on funding and public policies for WASH, ecological sanitation disposal, cultural environment and good sanitation practices for emergence of new sanitation system to secure and sustain well water quality. But the social acceptability of ecological disposal is limited by the society’s multicultural heritage. These findings could help in decision-making concerning urban groundwater quality protection in the African coastal cities.展开更多
