Etiologies and Associated Factors of Generalised Pruritus Sine Materia in the Dermatology-Venerology Department of CHUD-Borgou/Alibori (Benin)

Introduction: The aim was to identify the etiologies of generalised pruritus sine materia and to determine the associated factors in Parakou. Methods: This was a retrospective observational study conducted from January 2011 to June 2022. The patients included were of all ages and both sexes in whom the sine materia nature of the pruritus was noted after clinical examination. These patients had an etiological assessment available or not, complete or partial. For each patient, socio-demographic, socio-cultural, socio-economic and clinical data were collected using a pre-established survey form. They were then processed and analysed using Epi Data 3.1 and SPSS version 21 software respectively. Results: The incidence of generalised pruritus sine materia was 0.89% (73 cases/8214 consultants). The predominant etiologies were aquagenic pruritus (16.4%) and intestinal parasitosis (12.3%). After a bi-variate analysis, two risk factors were identified: frequency of towel change greater than 1 month (OR = 3.02;CI95% = 0.98 - 9.31;P = 0.0486) and use of cold water for bath (OR = 3.28;CI95% = 1.09 - 9.81;P = 0.0274). Conclusion: The etiologies and associated factors of generalised pruritus sine materia found in Parakou are varied but are linked to lifestyle. There is an urgent need to raise public awareness of the need to improve lifestyle in order to reduce the frequency of pruritus sine materia. .

Buruli Ulcer: Epidemiological, Clinical and Biological Profile of Patients in the Centre de Depistage et de Traitement d’Allada (Benin) from 2010 to 2014

Introduction: The objective of our work was to describe the epidemiological, clinical and biological profile of Buruli ulcer in “Centre de Dépistage et de traitement de l’ulcère de Buruli” (CDTUB) in Allada. Methods: A descriptive and retrospective study focused on new cases of Buruli ulcer received in the CDTUB of Allada from 2010 to 2014. The diagnosis of Buruli ulcer was based on epidemiological, clinical and biological arguments. Results: Over 5 years, 274 new cases of Buruli ulcer have been diagnosed. The average age of the patients was 12 years and the sex ratio was 0.8. The average time to first consultation was 45 days. Clinically, 61% had a joint functional limitation. Lesions were ulcerated in 69% of cases, category I (26%), category II (53%), category III (21%) and were present on the lower limbs in 57% of cases. Microscopy was positive in 65.7% of cases and PCR in 78.1% of cases. Microscopy supplemented by PCR confirmed the diagnosis in 81% of cases. Conclusion: The epidemiological, clinical and biological profile of Buruli ulcer in Allada was characterized by a predominant disease in children, a predominance of ulcerated forms and a decisive contribution of PCR to the diagnosis.

Epidemiological and Clinical Aspects of Neonatal Dermatoses at the National Teaching Hospital HKM of Cotonou Benin

Neonatal dermatoses (NND) are frequent, varied and of variable prognosis. The objective of this work was to study the epidemiological and clinical aspects of NND at the NTH-HKM. Methods: This was a cross-sectional descriptive and analytical study from December 1, 2014 to February 28, 2015. All newborns received in the Department of Pediatrics and Medical Genetics and with dermatosis were included. The diagnosis of dermatoses was clinical. Results: During the study period, 355 newborns had at least one NND on a total of 580 newborns received, a prevalence of 61.2%. The sex ratio was 1.54 and the average age was 3.11 days. Transient dermatoses were more frequent (80%), dominated by desquamation + xerosis (33.75%). Congenital melanocytic nevi (40.74%) and malformations and vascular tumors (18.52%) were the most noted pathological neonatal dermatoses. Only age was statistically associated with NND. Conclusion: DNH is common in newborns at the NTH-HKM. They were mostly transitory. Pathological conditions should be treated where appropriate.

Original Support of an after Piercing Lobular Keloid Scar: About a Case

Keloids are tissue repair formed by exuberant fibrosis appearing after a skin wound, burn, vaccination or post inflammatory (folliculitis or acne lesion). This condition causes standard aesthetic prejudice to those who are affected. Its management is difficult and its evolution meshes recurrences. We report here a case of giant keloid in the right ear lobe after a piercing and its support.
