Erysipelas; Bacterial dermohypodermitis; Skin bleaching
Introduction: The increase of both the frequency and severity of the bacterial dermohypodermitis (BDH) in Senegal suggests the existence of other risk factors outside of those classically known to be involved. Our study aimed to clarify the epidemiological, clinical and risk factors of BDH in Senegal.
Patients and methods: It was a retrospective, descriptive study based on records of all patients admitted for a DHD, in our department over a 30-year period (1982-2010).
Results: We collected 456 cases including 365 erysipelas and 91 necrotizing bacterial dermohypodermitis (NBDH). Nearly 50% of cases were observed during the last decade. The sex ratio was 0.3 and 0.9 whereas the average age was 40 years and 45 years respectively for erysipelas and NBDH. It was a severe form of erysipelas in 243 cases and classical one in 122 cases.
The predominant topography was the lower limb (81%). Simultaneous multifocal BDH was observed in 5 patients. The risk factors were skin bleaching (70%), venous insufficiency (37%), obesity (24%), a history of erysipelas (9.8%), lymphedema (9%) and pregnancy (3.5%). The portal of entry was identified in 76% of the cases. NBDH was secondary to Vibrio vulnificus infection in 2 cases and Pasteurella multocida in one case. The outcome was recurrence of the disease (9%), death (2%) and elephantiasis (1.5%).
Discussion: Our study reports on of the the most important BDH series in Sub-Saharan Africa. It highlights a marked increase in the frequency of BDH in our our country over the last years. In general, the condition was severe and typically affected young adults between 35 and 45 years old, usually females and mostly practicing skin whitening.
In Western countries, bacterial dermohypodermitis (BDH) has been widely studied and risk factors are well documented [1-3]. In the last decade, we have assisted to a marked increase of both the frequency and severity of BDH in everyday practice. This reality suggests the existence of other specific factors in our regions, apart from those traditionally known. However, very few studies have been conducted in Africa regarding this pathology [4-7].
Our objective was to specify the epidemiological profile, the clinical aspects, as well as the risk factors associated with BDH in Senegal.
Patients and methods
This was a retrospective study based on the records of patients admitted for a BDH in the Department of Dermatology of Dakar University Hospital from 1982 to 2010 (30 years). The diagnosis was clinical. For each file, we collected the age, gender, time of consultation, location, portal of entry, associated risk factors, skin bleaching, treatment, and evolution.
We collected 456 cases including 365 erysipelas and 91 necrotizing bacterial dermohypodermitis (NBDH).
The frequency of BDH over the 30 years has been illustrated in figure 1. Nearly half of the BDH (221 cases; 48.6%) have been observed during the last decade.
