RESUMO
BACKGROUND: Leprosy, or Hansen's disease, is a chronic infectious disease caused by Mycobacterium leprae. Togo achieved the target of eliminating leprosy as a public health problem in 2000 (less than 1 case/10 000 population). However, new cases of leprosy are still being reported. The aim of this study was to describe and map trends of leprosy cases notified in Togo from 2010 to 2022. METHODS: This was a descriptive cross-sectional study covering a thirteen-year period from January 1, 2010, to December 31, 2022. The data of the study were leprosy surveillance system's data collected monthly between 2010 and 2022. The estimated number of leprosy cases and the incidence rate of leprosy cases were reported for the whole population by region, by district, by calendar year (2010-2022) and by target sub-population (children under 15, women and people with disabilities). Observed case incidence rates were mapped by health district and by year. RESULTS: From January 1, 2010, to December 31, 2022, 1031 new cases of leprosy were diagnosed in Togo. The median age of subjects was 46 years (interquartile range: 33-60), with extremes from 4 to 96 years. Half the subjects were women (50.7%). Variations in the leprosy incidence rate by year show an increase between 2010 and 2022, from 0.7 cases /100,000 population to 1.1 /100,000 population respectively. From 2010 to 2022, the proportion of cases in children remained low, between 0 and 9%. The proportion of women fluctuated between 39.7% and 67.2% between 2010 and 2017, then stabilized at an average of 50% between 2018 and 2022. The proportion of multi-bacillary leprosy cases increased quasi-linearly between 2010 and 2022, from 70 to 96.6%. Mapping of leprosy cases showed that leprosy was notified in all Togo health districts during the study period, apart from the Lacs district, which reported no leprosy cases. CONCLUSION: Togo has achieved the elimination of leprosy as a public health problem. However, the increase in the number of new leprosy cases and the proportion of leprosy cases in children indicate that transmission of the disease is continuing and that supplementary measures are needed.

Introduction: Tele-expertise in dermatology represents an opportunity to change medical practice in response to the need for cost savings in the health sector. The aim of this study was to evaluate the medical activities of the pilot phase of the tele-expertise project in Togo. Method: A cross-sectional study was conducted in October 2020 on the 20 sites of the pilot phase. This evaluation consisted of a literature review and analysis of data posted on the tele-expertise platform. Results: A total of 738 (10.8%) of the 6810 dermatological consultations were posted on the tele-expertise platform. Of the 738 cases, the dermatologist's expertise did not allow a diagnosis to be made in 119 cases (16.1%). This expertise confirmed the single clinical hypothesis proposed by the health worker in 275 cases (37.3%) and allowed a diagnosis to be made among several clinical hypotheses in 30 cases (4.1%). On the contrary, the dermatologist's diagnosis was not included in the health worker's hypotheses in 201 cases (27.2%), and no clinical hypothesis was formulated in 113 cases (15.3%). The concordance between the clinical hypothesis proposed by the health worker and the diagnosis of the dermatologist was 48.8%. Regarding the acceptability of the tele-expertise, only one refusal was recorded. All patients were very satisfied with this practice. Conclusions: The results show the feasibility and acceptability of tele-expertise by health care personnel and patients. The diagnostic concordance of 48.8% shows the relative efficiency of task delegation.
Introduction: La téléexpertise en dermatologie représente une piste pour modifier l'exercice médical en réponse aux besoins d'économies de la santé. Le but de cette étude était d'évaluer les activités médicales de la phase pilote du projet de téléexpertise en dermatologie au Togo. Méthode: Il s'agit d'une étude transversale menée en octobre 2020 sur les 20 sites de la phase pilote. Cette évaluation consistait en une revue documentaire et l'analyse des données postées sur la plateforme de téléexpertise. Résultats: Au total, 738 (10,8 %) des 6 810 consultations dermatologiques ont été postées sur la plateforme de téléexpertise. Sur les 738 cas, l'expertise du dermatologue n'a pas permis de poser un diagnostic dans 119 cas (16,1 %). Cette expertise a confirmé l'hypothèse clinique unique proposée par l'agent de santé dans 275 cas (37,3 %) et a permis de conclure à un diagnostic parmi plusieurs hypothèses cliniques dans 30 cas (4,1 %). Au contraire, le diagnostic du dermatologue ne figurait pas dans les hypothèses de l'agent de santé dans 201 cas (27,2 %), et aucune hypothèse clinique n'avait été formulée dans 113 cas (15,3 %). La concordance entre l'hypothèse clinique proposée par l'agent de santé et le diagnostic du dermatologue était de 48,8 %. Concernant l'acceptabilité de la téléexpertise, un seul refus a été enregistré. Tous les patients étaient très satisfaits de cette pratique. Conclusions: Les résultats montrent la faisabilité et l'acceptabilité de la téléexpertise par les personnels de santé et les patients. La concordance diagnostique de 48,8 % montre la relative efficacité de la délégation de tâches.

BACKGROUND: In people with albinism (PWA), the deficiency of melanin increase the risk of skin cancers. The aim of this study was to determine the prevalence of skin cancers and characteristics of these detected skin cancers (histological types, localization) in PWA in 10 cities in Togo in 2019. METHODS: This is a cross-sectional study of medical records of PWA systematically examined during two mobile skin care clinics in 2019, as part of a programme for the prevention and management of skin cancers in these subjects. RESULTS: During the study period, 280 (95.2%) of the 294 PWA consulted, had developed skin lesions. Of the 280 PWA, the pathological reports from the medical records of 33 patients (11.8%; (95%CI = [8.2-16.2]) had concluded to non-melanoma skin cancers. The mean age of these 33 patients was 38.6 ± 15.2 years and the sex-ratio was 1. Their occupations were mainly resellers (21.2%), traders (15.2%) and farmers (12.2%). In the 33 patients, 54 cases of non-melanoma skin cancers were identified, with some patients having more than one tumor, and some of them having more than one (histologically confirmed) diagnosis. These 54 non-melanoma skin cancers were divided into 21 cases of invasive squamous cell carcinomas, 2 cases of Bowen's disease and 31 cases of basal cell carcinomas. These non-melanoma skin cancers mainly occurred in the head and neck (33 cases; 61.1%), the upper limbs (15 cases; 27, 8%) and the trunk (4 cases; 7.4%). CONCLUSION: The results of this study show a high prevalence of skin cancers among PWAs in Togo in 2019, only non-melanoma skin cancers. In addition, they illustrate the role of ultraviolet rays with regard to the localization of skin cancers and the occupations of patients. Popularization and compliance with photo protection measures, systematic and regular examination of the skin of these PWAs will allow early detection and treatment of these skin cancers.

BACKGROUND: Acne is a chronic inflammatory condition affecting the pilosebaceous follicle that mainly affects adolescents and young adults. The aim of this study was to assess the quality of life (QOL) of patients with acne, and to determine the correlation between the QOL and the severity of acne, in Lomé (Togo). METHOD: From July 2017 to February 2018, we conducted a study in three dermatology departments of Lomé. The clinical evaluation of acne and assessment of the QOL were done using the ECLA (Echelle de Cotation des Lésions d'acné) and CADI (Cardiff Acne Disability Index) scores respectively. RESULTS: We enrolled 300 patients aged 12 to 52 years; 71.3% of whom were female. The face was affected by acne in 100% of cases and papulopustular acne was the most common clinical form (66.7%). Acne was mild to moderate in 162 patients (54%) and severe in 138 (46%). Impairment was observed in all patients' QOL (scores ranged from 1 to 14 points). There was a positive correlation between severity of acne and QOL impairment in the patients (r = 0.21; p = 0.0002). We also found a positive correlation between overall CADI score and factors F1 and F3 of the ECLA scale: the severity of facial acne (r = 0.15; p = 0.0073) and the presence of scars (r = 0.21; p = 0.0002). In contrast, the global ECLA score was significantly correlated with items 2, 3, and 5 of the CADI questionnaire: the patient's relationship (r = 0.13; p = 0.0241), avoidance behaviors (r = 0.21; p = 0.0002) and perception of acne (r = 0.16; p = 0.0067). CONCLUSION: Acne negatively impacts the QOL of patients. The severity of acne has an impact on the patient's relationships, avoidance behaviors and perception of the acne.

BACKGROUND: In the global strategy to eliminate leprosy, there remains a need for early case detection to successfully interrupt transmissions. Poor knowledge about leprosy and leprosy-related stigma are key drivers of delayed diagnosis and treatment. Sensitization campaigns to inform and increase awareness among the general population are an integral part of many national neglected tropical disease programs. Despite their importance, the effectiveness of such campaigns has not been rigorously studied in the West African context. A multilingual rural setting with low health literacy in this region presents challenges to the potential impact of sensitization campaigns. OBJECTIVE: The primary objective of this study is to assess the causal effect of common practice community sensitization campaigns on leprosy-related knowledge and stigma at the community level and among community health volunteers. Additionally, we will test the potential of novel educational audio tools in the 15 most prominent local languages to overcome literacy and language barriers and amplify sensitization campaigns. METHODS: We will conduct a cluster randomized controlled trial using a sequential mixed methods approach in 60 rural communities across all regions of Togo, West Africa. The study features 2 intervention arms and 1 control arm, with intervention and control assignments made at the community level through randomization. Communities in intervention arm 1 will receive a sensitization campaign in line with the current Togolese national neglected tropical disease program. Communities in intervention arm 2 will receive the same sensitization campaign along with educational audio tools distributed to community households. The control arm will receive no intervention before data collection. Quantitative outcome measures on knowledge and stigma will be collected from a random sample of 1200 individuals. Knowledge will be assessed using the 9-item standardized Knowledge, Attitudes, and Practices Questionnaire. Stigma will be measured using the 7-item Social Distance Scale and the 15-item Explanatory Model Interview Catalogue Community Stigma Scale. We will estimate intention-to-treat effects at the individual level, comparing the outcomes of the intervention and control arms. In an accompanying qualitative component, we will conduct in-depth interviews with community members, community health volunteers, and health care workers in both treatment arms and the control arm to explore intervention and stigma-related experiences. RESULTS: This paper describes and discusses the protocol for a mixed methods cluster randomized controlled trial. Data collection is planned to be completed in June 2024, with ongoing data analysis. The first results are expected to be submitted for publication by the end of 2024. CONCLUSIONS: This trial will be among the first to test the causal effectiveness of community-based sensitization campaigns and audio tools to increase knowledge and reduce leprosy-related stigma. As such, the results will inform health policy makers, decision-makers, and public health practitioners designing sensitization campaigns in rural multilingual settings.

RESUMO
BACKGROUND: As of May 2022, 15 countries have declared that they have reached their trachoma elimination targets, but only 13 of them, including Togo, have been validated by the World Health Organization as having eliminated the disease as a public health problem. The aim of this study was to describe the broad interventions that have supported the elimination of trachoma as a public health problem in Togo from its inception in 2006 to the validation of its elimination in 2022. METHOD: A review and compilation of data and information contained in the country's submission to World Health Organization for validation of trachoma elimination as a public health problem was conducted. Data from national and local surveillance systems and reports on actions taken after achieving the elimination target were also included. RESULTS: Togo has achieved the elimination of trachoma as a public health problem by 2022. The prevalence of follicular trachoma among children aged 1-9 years is <5% in all nationally defined administrative units suspected of having trachoma after stopping mass treatment for at least 2 years. The prevalence of trichiasis among persons aged 15 years and older is less than 0.2% in all administrative units previously endemic for trachoma and evidence of the ability to manage incident cases of emerging trichiasis in the community has been demonstrated. The key of the success in the elimination process was primarily the political commitment of the health authorities with financial and technical support from various international organizations. CONCLUSION: The elimination of trachoma as a public health problem in Togo is a real success story that can serve as an example for the elimination of other neglected tropical diseases in Africa. But regular monitoring and surveillance is essential to avoid the re-emergence of such disease in the country.

INTRODUCTION: Skin neglected tropical diseases (NTDs), are endemic and under-diagnosed in many lower-income communities. The objective of this study was to determine the prevalence of skin NTDs and fungal infections in two primary schools and a community setting in rural Togo. METHOD: This was a cross-sectional study that took place between June-October 2021. The two primary schools are located on the outskirts of Lomé, the capital city. The community setting was Ndjéi, in north-east Togo. Study sites were purposively selected. Dermatologists examined the skin of study participants. Diagnosis of skin NTDs were made clinically. RESULTS: A total of 1401 individuals were examined, 954 (68.1%) from Ndjéi community, and 447 (31.9%) were children in the schools. Cutaneous skin infections were diagnosed in 438 (31.3%) participants, of whom 355 (81%) were in community settings. There were 105 observed skin NTDs (7.5%). Within the school setting, there were 20 individuals with NTDs (4.5% of 447 participants), and 85 NTDs (8.9%) from 954 community participants. Across all settings 68/1020 (6.7%) NTDs were in children, and 37/381 (9.7%) in adults. In addition, there were 333 observed mycoses (23.8% prevalence). The main cutaneous NTDs diagnosed were scabies (n = 86; 6.1%) and suspected yaws (n = 16, 1.1%). The prevalence of scabies in schools was 4.3%, and 7.0% in the rural community. One case of leprosy was diagnosed in each school and the rural community, and one suspected Buruli Ulcer case in the community. In the school setting, five (6%) children with a skin NTD reported being stigmatised, four of whom had refused to attend school because of their dermatosis. In Ndjéi, 44 (4.6%) individuals reported having experienced stigma and 41 (93.2%) of them missed at least one day of school or work. CONCLUSION: This study shows that the burden of scabies and skin infections such as superficial mycoses is high in the school and rural community settings in Togo, with associated presence of stigma. Improved health promotion and education across institutional and community settings may reduce stigma and encourage early reporting of skin infection cases to a health facility.

OBJECTIVE: The aim of this study was to identify the factors associated with skin cancers in people with albinism (PWA) in Togo. METHOD: This is a retrospective analytical study of the records of PWA examined during five dermatological consultation campaigns from 2019 to 2021. RESULTS: During the study period, 517 PWA were seen. Sixty-four (12.3%) of these PWA had presented with 137 cases of skin cancer. The sex ratio (M/F) was 0.9. The average age of PWA with skin cancer was 39.69 ± 15.61 years and that of PWA without skin cancer was 19.17 ± 15.24 years (p ≤ 0.001). The 137 cases of skin cancers were dominated by basal cell carcinomas (45.9%). These skin cancers were located preferentially in the cephalic region (77 cases; 56.2%), followed by the upper limbs (33 cases; 24.1%). In multivariate analysis, the risk factors for skin cancers in PWA were age over 39 years (p ≤ 0.001) and the presence of actinic keratoses (p ≤ 0.001). In contrast, the presence of ephelides (p=0.018) was a protective factor. CONCLUSION: This study confirms that advanced age and actinic keratoses are risk factors for skin cancer in PWA, in connection with the cumulative role of solar radiation. Its originality lies in the identification of ephelides as a protective factor. The knowledge and consideration of these risk factors will make it possible to optimise strategies for the prevention of skin cancers in PWA.
RESUMO
OBJECTIVE: The aim of this case-control study was to look for an association between hypertension and acne keloidalis nuchae (AKN) in black subjects. RESULTS: We recruited 303 consenting subjects comprising 101 patients with AKN and 202 controls, case-matched by age (± 5 years). The mean patients age was 34.9 ± 10.7 years versus 35.6 ± 11.2 years for controls. The average duration of AKN progression in cases prior to consultation was 1831 days (5 years). The most frequently observed AKN lesions were papules (73/101; 72.3%), fibrous scars (42/101; 41.6%) and folliculitis/pustules (41/101; 40.6%). In terms of quality of life, the mean score of dermatology life quality index was 8.3 ± 5.2 (extremes: 0 to 22). In multivariate analysis, having a BMI of 25 kg/m2 or more (OR = 4.91; p < 0.001) and having systolic hypertension (OR = 1.22; p = 0.010) were associated with AKN.

BACKGROUND: People with albinism (PWA) are targets of prejudice and social exclusion and have limited access to specialized medical care and resources. Our study aimed to describe the epidemiological and dermatological profile of PWA in Togo. METHOD: We carried out a cross-sectional study of 294 medical records of PWA systematically examined during two mobile skin care clinics in 2019. RESULTS: The mean age of the patients was 22 ± 16.5 years, and the gender ratio (M/F) was 1. A family history of albinism was reported in 27.9% of cases, and consanguinity between the parents was found in 24.1% of PWA. Dermatological lesions on physical examination were present in 95.2% of PWA. These lesions were elastosis/wrinkles (82.9%), ephelides (79.6%), actinic keratoses (60.0%), actinic cheilitis (50.0%), and cutaneous carcinomas (11.8%). The mean age of PWA with skin carcinomas was 38.6 years. Fifty-four cases of cutaneous carcinomas had been diagnosed (31 cases of basal cell carcinoma, 21 cases of squamous cell carcinoma, and 2 cases of Bowen's disease) and were located mainly in the cephalic region (61.1%) and upper limbs (27.8%). Cryotherapy and/or excisional biopsies were the treatments for premalignant and malignant lesions. All PWA were sensitized on sun protection. CONCLUSIONS: This study shows the basic picture of dermatological characteristics of PWA with a high frequency of photo-induced lesions and skin cancers. The popularization and respect of photoprotection measures and regular skin examination of these PWA for early detection and management of lesions will reduce their morbidity and mortality.

OBJECTIVE: The aim of this study was to study the histopathological patterns of skin lesions in persons with albinism (PWA) in Togo in 2019. METHOD: During two mobile skin care clinics in 2019, biopsies/excisional biopsies were performed in PWA in case of clinical doubt or in front of lesions suspected to be cancerous for histological examination. Anatomopathological reports were thus analysed. RESULTS: During the two mobile skin care clinics, 115 biopsies/excisional biopsies were carried out in 79 PWA, with a mean age of 24 ± 16.1 years. Histological examination led to a diagnosis in 110 cases (95.6%) and was inconclusive in 5 cases (4 cases of uncertain histological diagnosis and one case of nonspecific histological lesions). Fourteen different histological diagnoses were made, with a frequency ranging from 0.9% (one case) to 26.9% (31 cases). The four most frequent diagnoses in descending order were basal cell carcinomas (BCCs) (31 cases; 26.9%), invasive squamous cell carcinomas (SCCs) or Bowen's disease (23 cases; 20%), keratosis (20 cases; 17.3%), and cysts (seven cases; 6.1%). The 54 skin carcinomas were diagnosed in 33 (41.8%) of the 79 patients who underwent skin biopsies/excisional biopsies. The BCC/SCC ratio was 1.3. No cases of cutaneous melanoma had been diagnosed. CONCLUSION: Skin cancers represent the main histological diagnosis in PWA (46.9%) in Togo in 2019. The pattern of cutaneous malignancies in PWA shows the same trend as that seen in Caucasians with a predominance of basal cell carcinomas.
