[Place of theses and dissertations in the scientific publications of dermato-venereology teachers of the University of Lome (Togo)]. / Place des thèses et mémoires dans les publications scientifiques des enseignants de dermato-vénéréologie de l'université de Lomé (Togo): Ce travail a fait l'objet d'une communication orale lors des 5e journées dermatologiques de Ouagadougou (Burkina Faso) en octobre 2017.

The aim of this study was to situate the place of theses and dissertations (senior healthcare technicians, D.E.S or master) in the scientific publications of dermato-venerology teachers at the University of Lomé (Togo). We listed the theses and dissertations on dermato-venerology between 1990 and 2016, in three institutions of the University of Lomé and consulted databases (Medline, Inist, registers of the service) to search for publications by teachers during this period. A total of 41 theses and 50 dissertations were completed, on infectious dermatoses and STI/HIV (46.1%), immunoallergic dermatoses (11.0%) and tumour dermatoses (8.8%). Of these 91 works, 56 (including 28 theses) were published in indexed (21 theses and 26 dissertations) or non-indexed (7 theses and 2 dissertations) journals. These 56 publications represented 27.7% of the 202 publications made by the dermato-venerology teachers at the University of Lomé during this period. Of the 28 published theses, the MD student was the first author in one case (3,6%) This work shows that theses and dissertations in dermato-venerology represent almost one third of the publications in this discipline in Togo.

[Risk factors associated with acne keloidalis nuchae, in black subjects: A case-control study]. / Facteurs de risque associés aux folliculites fibrosantes de la nuque chez le sujet noir : étude cas-témoins.

OBJECTIVE: The aim of this case-control study was to identify risk factors associated with acne keloidalis nuchae (AKN), seen in a dermatology clinic in Lomé (Togo). PATIENTS AND METHODS: This was a case-control study conducted from January to December 2018. Patients were recruited at outpatients dermatological clinics and controls were recruited at outpatients dermatological clinics and then in other hospital departments. RESULTS: We recruited 303 consenting subjects, comprising 101 patients with AKN and 202 controls case-matched by age (±5 years). The mean patient age was 34.9±10.7 years vs. 35.6±11.2 years for controls. The most frequently observed AKN lesions were papules (73/101; 72.2%), fibrous scars (42/101; 41.5%) and folliculitis/pustules (41/101; 40.6%). In multivariate analysis, the following factors were associated with AKN: excess weight (adjusted odds ratio=4.8; 95% CI=[2.3-11.7]) or obesity (OR=9.2; 95% CI=[2.1-34.2]), bleeding during hairdressing either occasionally (aOR=13.9; 95% CI=[5.1-40.0]) or systematically (aOR=22.1; 95% CI=[6.2-40.7]), hairdressing procedures less than once per week (aOR=10.1; 95% CI=[3.2-50.8]), and extremely close cropping of hair (aOR=4.9; 95% CI=[2.8-15.5]). CONCLUSION: AKN is common in young adults. Excess weight or obesity, bleeding during hairdressing, and frequency and style of hairdressing are all associated factors. The results of this study stress the importance of limiting injury during hairdressing, and of refraining from shaving or cropping hair without a trimmer. Since management of AKN is extremely difficult, identification of associated risk factors allows suitable preventive approaches to be adopted.

Position Statement on Atopic Dermatitis in Sub-Saharan Africa: current status and roadmap.

BACKGROUND: The first International Society of Atopic Dermatitis (ISAD) global meeting dedicated to atopic dermatitis (AD) in Sub-Saharan Africa (SSA) was held in Geneva, Switzerland in April 2019. A total of 30 participants were present at the meeting, including those from 17 SSA countries, representatives of the World Health Organization (WHO), the International Foundation for Dermatology (IFD) (a committee of the International League of Dermatological Societies, ILDS www.ilds.org), the Fondation pour la Dermatite Atopique, as well as specialists in telemedicine, artificial intelligence and therapeutic patient education (TPE). RESULTS: AD is one of the most prevalent chronic inflammatory skin diseases in SSA. Besides neglected tropical diseases (NTDs) with a dermatological presentation, AD requires closer attention from the WHO and national Departments of Health. CONCLUSIONS: A roadmap has been defined with top priorities such as access to essential medicines and devices for AD care, in particular emollients, better education of primary healthcare workers for adequate triage (e.g. better educational materials for skin diseases in pigmented skin generally and AD in particular, especially targeted to Africa), involvement of traditional healers and to a certain extent also patient education, bearing in mind the barriers to effective healthcare faced in SSA countries such as travel distances to health facilities, limited resources and the lack of dermatological expertise. In addition, several initiatives concerning AD research in SSA were discussed and should be implemented in close collaboration with the WHO and assessed at follow-up meetings, in particular, at the next ISAD meeting in Seoul, South Korea and African Society of Dermatology and Venereology (ASDV) meeting in Nairobi, Kenya, both in 2020.

Reasons for inpatient admissions to the dermatology department in Lomé, Togo : Trends between 1992 to 2005 and 2005 to 2016.

The aim of this study was to report the frequency of and reasons for dermatology admissions in Lomé (Togo) between 2005 and 2016. This retrospective study examined records from August 2005 to December 2016 from the dermatology departments of the two teaching hospitals in Lomé, Togo. During the study period, 454 (1.1%) of the 40,231 new patients who consulted in dermatology were hospitalized, with a total of 460 separate admissions (mean dermatology hospitalizations per year: 42). Patients' mean age was 43±17.6 years and the sex ratios (M/F) was 0.6. The main reasons for hospitalization were Stevens-Johnson syndrome (SJS), also known as erythema multiforme majus, and toxic epidermal necrolysis (TEN) (28.9%), followed by bullous erysipelas (21.4%), connective tissue disease (10.3%), and Kaposi sarcoma-associated herpes virus (9%). The average length of stay in hospital was 15±13.7 days. The diagnosis that accounted for the longest mean length of stay was deep fungal infections (63.5 days) (P<0.0001). We recorded 39 deaths, for a death rate of 8.6%. Death rates were highest for deep fungal infections (37.5%) and SJS/TEN (12.2%). Our study confirmed the low rate of inpatient admissions in dermatology and revealed a change in the reasons for hospitalization and a decrease in mortality in dermatology in Lomé, compared with the previous 13 years. This decrease in mortality may be attributed to the improvement of hospital care provided to patients but also by the generalization of antiretroviral treatment in Togo that began more than 10 years ago.

Non-nucleoside reverse transcriptase inhibitors (NNRTIs)-induced Stevens-Johnson syndrome and gynecomastia in an HIV-infected child: A case report.

BACKGROUND: Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are antiretroviral drugs often used in the first-line treatment regimen of HIV1 infection worldwide. We report a case of successive gynecomastia and Stevens-Johnson syndrome (SJS) respectively induced by efavirenz and nevirapine in a single patient. CASE REPORT: A 16-year-old boy, HIV1-infected since birth, was started on antiretroviral treatment (ART) in August 2015 and was taking a regimen comprising abacavir, lamivudine and efavirenz. In April 2016, when his weight reached 35kg, abacavir was replaced with tenofovir. Bilateral breast enlargement, previously hidden by the patient, was diagnosed two years after the start of ART. History-taking, physical examination and laboratory tests ruled out known causes of gynecomastia, and efavirenz was thus considered the most likely cause. This drug was then withdrawn and replaced with nevirapine in July 2017. Thirty-three days after the patient started nevirapine treatment, a skin rash appeared. Physical examination revealed erythematous macules and flaccid bullae with estimated skin detachment of 10%. There were also conjunctival, buccal and genital lesions. A diagnosis was made of SJS induced by nevirapine. Three months after withdrawal of efavirenz, breast size decreased by 3cm on the left breast and 2cm on the right breast; two months after the SJS, cutaneous sequelae alone persisted, such as diffuse hyperchromic macules. DISCUSSION: Recognition of gynecomastia as a side-effect of efavirenz is important to allow the condition to be treated while it is still potentially reversible. Moreover, when efavirenz is replaced, a protease inhibitor should be preferred to nevirapine.

Chronic leg ulcers in hospitalized patients in Lomé, Togo: 125 cases.

The aim of this study was to document the profile and causes of chronic leg ulcers (CLU) in patients hospitalized in Lomé, Togo. This retrospective study reviewed records from the dermatology departments (CHU Sylvanus Olympio and Campus, and the dermatology center of Gbossimé) from 2000 to 2017 and from the general surgery department of CHU Sylvanus Olympio from 2013 to 2017 to identify cases. In all, 125 cases of CLU were identified during the study period. The patients' mean age was 56.6 years and the sex ratio (M/F) was 0.89. The average time from CLU onset to consultation was 10.9 weeks (range : 7 weeks to 4 years). They were mainly associated with a history of diabetes (32 cases), arterial hypertension (16 cases), varicose veins (14 cases), and malnutrition (14 cases). The main causes were : ulcers of infectious origin in 49.6% of cases (including 38 with phagedenic ulcers), ulcers of vascular origin in 36% (including 21 cases with a venous ulcer) and diabetic ulcers in 8.8% of cases. The ulcer was unilateral in 122 patients (67 on the right and 55 on the left) and bilateral in 3 patients. The locations were the foot in 56 cases, the leg in 37 cases, and leg and foot in 32 cases. In addition to dressings, surgical debridement was performed in 23 patients, followed by skin autografts for 16. Amputation was performed for 31 patients. Sixteen (12.8%) of the 125 patients died. Our study observed a high rate of phagedenic ulcers among CLU in Togo. It also pointed to a problem explaining the very high mortality rate: delayed consultation by patients who arrive only after the onset of complications.

Stevens-Johnson and Lyell syndromes in children in a hospital setting in Lomé, Togo, from 2000 to 2015.

OBJECTIVE: The aim of this study was to document the profile of children with Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN, also called Lyell syndrome) in hospital settings in Lomé, Togo. METHOD: This descriptive retrospective study examined the records of children aged 0 to 15, seen and/or hospitalized in the dermatology department of CHU-SO Lomé and diagnosed with SJS/TEN between 2000 and 2015. RESULTS: Records were identified for 14 children with these diagnoses during the study period. Their average age was 10.9 ± 3.9 years. The average time between taking the apparently causal medication and the onset of symptoms was 10.5 days (range: 4 to 21 days). SJS accounted for 64.3% of the cases. Six children with SJS and one with TEN had ocular involvement. Antibacterial sulfonamides were the main drug involved for 43% of children, followed by anticonvulsants for 14/3%. CONCLUSION: Our results show that SJS/TEN is rare but serious in children. The antibacterial sulfonamides used for the treatment of malaria and anticonvulsants are their most frequent cause.

Morbidity and mortality in HIV-infected children on antiretroviral therapy in Togo.

the aim of this study was to evaluate the mortality and morbidity of HIV-infected children on highly active antiretroviral treatment (HAART) in Togo. this is a retrospective study of HIV-infected children on HAART in the 25 largest centers of HIV/AIDS care in Togo. the study included 1861 children (sex-ratio=0.99). Among them, 35.6 % were in WHO clinical stages 3 or 4 at the beginning of HAART. The most common opportunistic infections were coughing and pneumonia (37.1 %), gastroenteritis (11.3 %), various bacterial infections (10.4 %), and pruritus (10.4 %). The incidence of death was estimated at 4.5 per 100 person-years. Mortality was highest during the first year of antiretroviral therapy. The survival rate at 12 months of ART was 92.6 %. Children who began HAART at WHO clinical stage 4 had a significantly lower survival rate than the others (P<0.0001). The presence of a side effect of HAART (P=0.041), and hospitalization (P<0.001) were significantly associated with death in these children. although the new recommendations for medical care require early initiation of HAART, the improved performance of programs to prevent maternal-infant transmission remains crucial in reducing morbidity and mortality of children on HAART in Togo.

[Factors associated with the severity of acute ocular involvement in Stevens-Johnson syndrome and toxic epidermal necrolysis in sub-Saharan Africa]. / Facteurs de risque associés à la sévérité de l'atteinte oculaire au stade aigu du syndrome de Stevens-Johnson et de la nécrolyse épidermique toxique en Afrique subsaharienne.

AIM: The purpose of this study was to identify risk factors associated with the severity of acute ocular involvement in Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) in sub-Saharan Africa. PATIENTS AND METHOD: A retrospective study was carried out at the dermatology department in collaboration with the ophthalmology department for SJS/TEN patients between January 2000 and December 2016 in Lomé (Togo). The severity of acute ocular involvement was evaluated using the Power classification, and the drug eruption score was assessed using de Bastuji-Garin classification. RESULTS: A total of 107 cases of SJS/TEN (84 cases of SJS, 20 cases of TEN and 3 cases of overlap syndrome) were analyzed. There were 71 women and 36 men, with an average age of 32.3±12.5 years (range: 5 to 75 years). Sulfonamides (37.4%) were the most commonly used drugs followed by nevirapine (22.4%). HIV serology was positive in 46 (58.2%) of the 79 patients tested. A total of 54 (50.5%) patients had acute ocular involvement, which was mild in 29.9% of patients, moderate in 13.1% and severe in 7.5%. In multivariate analysis, exposure to sulfadoxine was the sole factor associated with moderate or severe acute ocular involvement in SJS/TEN (adjusted odds ratio=3.3; 95% CI=[1.1; 10.2]). CONCLUSION: Exposure to sulfadoxine was identified in our study as a risk factor associated with the severity of acute ocular involvement in SJS/TEN. Multicenter studies should be conducted in sub-Saharan Africa to confirm this associated risk factor.

[Vascular Cutaneous Abnormalities in Togo: a 120-Case Study]. / Anomalies vasculaires cutanées au Togo : étude de 120 cas.

The purpose of this study was to describe the epidemio-clinical profile, and treatment of vascular cutaneous abnormalities in Togo. It was a retrospective study of patients recorded in dermatology for vascular cutaneous abnormality between 1998 and 2017. During the study period, 120 (0.1%) of 88,869 patients received in dermatology have consulted for vascular cutaneous abnormalities. Their mean age was 25.3 months and the sex-ratio (M/F) 0.4. The most recurring vascular cutaneous abnormalities were vascular tumors (97 cases; 80.8%), mainly infantile hemangioma (IH) (93 cases; 77.5%). The mean time of onset of IH after birth was 2.9 months. The IH (54 cases; 50.5%) and port wine stains (8 cases, 53.3%) were predominantly localized at the cephalic region and Klippel-Trenaunay syndrome cases on lower limbs. We opted for a therapeutic abstention in the majority of the patients (50 cases of IH, 16 cases of simple vascular abnormalities, all Klippel-Trenaunay syndrome cases and telegiectasia cases). Of the 43 IH cases treated, the main drugs used were corticosteroids (23 cases of which 17 between 1998 and 2011 and 6 from 2012) followed by propranolol (11 cases from 2012). We had a favorable response in 9 of the 15 patients seen again. Cutaneous vascular abnormalities are very rare in dermatology in Togo and are dominated by IH with female predominance. In IH treatments, propranolol use, started in 2012 in Togo, is increasing when corticotherapy has declined.

L'objectif de cette étude était de décrire le profil épidémioclinique et thérapeutique des anomalies vasculaires cutanées au Togo. Il s'agit d'une étude rétrospective portant sur les dossiers des patients reçus en dermatologie pour une anomalie vasculaire cutanée entre 1998 et 2017. Durant la période d'étude, 120 (0,1 %) des 88 869 patients reçus en dermatologie ont consulté pour une anomalie vasculaire cutanée. L'âge moyen des patients était de 25,3 mois et le sex-ratio (H/F) de 0,4. Les anomalies vasculaires les plus recensées étaient les tumeurs vasculaires (97 cas ; 80,8 %), principalement les hémangiomes infantiles (HI) [93 cas ; 77,5 %]. Le délai moyen d'apparition des HI après la naissance était de 2,9 mois. Les HI (54 cas ; 50,5 %) et les angiomes plans (8 cas, 53,3 %) étaient localisés de façon prépondérante à la région céphalique et les cas de syndrome de Klippel-Trenaunay aux membres inférieurs. Nous avons opté pour une abstention thérapeutique chez la plupart des patients (50 cas d'HI, 16 cas de malformations vasculaires simples, tous les cas de syndrome de Klippel-Trenaunay et le cas de télangiectasies). Sur les 43 cas d'HI traités, les principaux médicaments utilisés étaient les corticoïdes (23 cas dont 17 entre 1998­2011 et 6 à partir de 2012) suivis du propranolol (11 cas à partir de 2012). Nous avions noté une réponse favorable chez 9 des 15 patients revus. Les anomalies vasculaires cutanées sont très rares en dermatologie au Togo et sont dominées par les HI, avec une prédominance féminine. Dans le traitement des HI, l'usage du propranolol, débuté en 2012 au Togo, est en augmentation pendant que celui de la corticothérapie baisse.
