[A case of rhinofacial entomophthoromycosis in Soudano-Sahelian tropical climate in Burkina Faso]

We describe a rhinofacial entomophthoramycosis case in a sexagenarian (65 years old) housewife. She was immunocompetent and resident of Burkina Faso. She consulted both the service of dermatology and the service of stomatology of the Teaching Hospital of Bobo-Dioulasso in February 2016 for a diffuse facial tumefaction evolving over six months. This tumefaction was associated with headaches and a left nasal obstruction. Histological examination of the lesion showed an important and polymorphic inflammatory reaction. Also, a filamentous fungus with wide non-septated hyphae and right-angled fungal branching, consistent with mucormycosis was isolated. Mycological diagnosis based on fungal culture with Sabouraud medium without any antibiotic and cyclohexemide after incubation at 27°C and at 30°C was negative. Furthermore, it was not possible to amplify the DNA extracted from biopsy. Antifungal therapy based on the administration of fluconazole per os at 800mg/day was started allowing clinical improvement. This is the first case of a rhinofacial entomophtharomycosis documented in Bobo-Dioulasso. Rhinofacial entomophthoromycosis is largely unknown, even in tropical regions such as Burkina Faso. This lack of knowledge results in a delay in the diagnosis, and subsequently a bad prognosis. It is therefore urgent to improve knowledge on this disease to guide diagnostic steps, prognosis of outcome, and antifungal therapy.

[Cryptococcosis: a potential aetiology of facial ulceration]

Cutaneous cryptococcosis is an uncommon aetiology of chronic facial ulceration but which may be associated to a potentially lethal focus of cryptococcosis.

OBSERVATION

A 35-year-old AIDS patient under antiretroviral therapy, presented with a chronic facial ulceration. Histopathological examination of a biopsy of the facial ulceration showed an inflammatory granuloma and masses of yeasts. Mycological culture of the cerebrospinal fluid revealed Cryptococcus neoformans. The diagnosis of AIDS-related cutaneous cryptococcosis of the face and cryptococcal meningitis was concluded.

DISCUSSION

Cryptococcosis should be thought as a potential aetiology of a chronic facial ulceration in an AIDS patient. Screening of other foci of the cryptococcosis such as that of the central nervous system is mandatory. Mycological examinations are of great interest for the diagnosis in rare resources setting.

[Multiple sites extrapodal actinomycetoma: Favorable outcome to treatment with a combination of cotrimoxazole and NSAI]

Mycetoma is a bacteriological or fungal infectious disease affecting the skin and/or soft tissues, which can be complicated by bone involvement. The most common feature is a tumor of the foot, but extrapodal localizations have been described. We report one case of a 47-year-old man who presented with tumefaction of a leg with multiple skin fistulae. Histopathological examination permitted to confirm the diagnosis of actinomycetoma and TDM showed the degree of bone and soft tissues involvement. Our case was characterized by the very inflammatory aspect of the tumor, its localization to the leg without foot involvement, the modest functional signs compared to the importance of radiological bone involvements, the deep destruction of the fibula while the tibia was apparently intact and the good response to treatment. In spite of its characteristic features, diagnosis of mycetoma is still late in our country, often with bone and/or articular spread. Priority may be given to measures for reduction of mycetoma diagnosis lateness.

[Darier's disease: three cases of psychosocial difficulties in an African setting]

BACKGROUND

Darier's disease is a rare disease. Multiple clinical forms have been observed, but the psychosocial aspects in Africa are rarely described. We report three cases involving difficulties regarding social integration.

OBSERVATIONS

Case no. 1: a 19-year-old woman consulted for hyperchromic, greyish, keratotic papules, grouped in small plaques scattered all over the body. She had trouble finding a husband and was rejected by her peers. Case no. 2: a 20-year-old woman presented generalized keratotic, vegetative lesions. She was rejected by her husband because of the lesions. Like patient no. 1, she was unable to purchase her prescribed treatment. Case no. 3: a 33-year-old blacksmith presented Darier's disease with lesions on the interscapular region and chest. He was epileptic and depressive and was partly rejected by his family.

DISCUSSION

Darier's disease, diagnosed on the basis of anatomoclinical factors, had a major impact on the social integration of all three patients. These generalised disfiguring forms of the disease adversely affect the quality of life and their association with neuropsychiatric disorders is another major handicap.

CONCLUSION

Difficulties concerning social integration and therapeutic problems must be considered in the management of Darier's disease in Africa.

[Estimation of the execution of the national strategy of leprosy elimination in the "Hauts Bassins" region in Burkina Faso]

BACKGROUND

Burkina Faso achieved the leprosy elimination as a public health problem but this benefit was being lost. So, the National Program for Fighting against Leprosy has defined a strategy to reverse this situation. The aim of this survey was to evaluate the performance of the national program in the execution of this strategy in the region of "Hauts Bassins" (Burkina Faso) from 2005 to 2009.

METHOD

The survey was led through the five sanitary districts of the region. It consisted in interview with the mean actors of leprosy control program and the analysis of the data notified on the leprosy cases, in order to estimate the progression of the key indicators of detection and follow-up care for patients having leprosy.

RESULTS

During the survey period, 248 cases of leprosy were recorded including 236 new cases and 12 relapses. The prevalence of leprosy was 0.28 per 100 000 inhabitants in 2009. The detection rate decreased from 3.77 per 100 000 in 2005 to 2.75 per 100 000 in 2009. Among the 236 new cases of leprosy, 194 (82.2 %) were multibacillary form (MB). MB patients proportion increased from 69,3 % in 2005 to 91.1 % in 2009. The proportion of children was on average 3.8 %, the one of female cases 38.9 %. Newly diagnosed cases with grade 2 disabilities moved up from 21.4 % in 2005 to 42.2 % in 2009. The completion of cure rate was globally 88.26 %. The losts from follow-up among the patients who started multi-drug therapy were 7.14 %.

CONCLUSION

The aim of the leprosy elimination as a public health problem is achieved but some challenges may be taken up, particularly in the organization of leprosy detection by the heath structures.

[Multiple facial squamous cell carcinomas in a child, revealing a xeroderma pigmentosum]

BACKGROUND

Squamous cell carcinoma of the skin is very rare in children. One of its most common risk factors is xeroderma pigmentosum (XP), an autosomal recessive disease characterized by defective cellular DNA repair, and hypersensitivity to ultraviolet radiation.

CASE REPORT

We report a case of XP in a 7-year-old black African boy, revealed by squamous cell carcinomas of the inferior lip and upper left eyelid.

DISCUSSION

In sub-Saharan regions, the early diagnosis of XP is difficult because of its uncommon occurrence on black skin and black skin specificities. The strong sun radiation in the tropics and a late diagnosis make XP treatment challenging. Thus, prevention in patients' families is mandatory.

Longitudinal effect following initiation of highly active antiretroviral therapy on plasma and cervico-vaginal HIV-1 RNA among women in Burkina Faso

BACKGROUND

Highly active antiretroviral therapy (HAART) could decrease HIV-1 transmissibility by reducing genital and plasma HIV-1 RNA.

METHODS

We evaluated the effect of HAART on genital and plasma HIV-1 RNA in a cohort of 39 antiretroviral-naïve women in Burkina Faso. Cervico-vaginal lavages were collected before HAART initiation and at six visits over 28 weeks while on HAART. Blood samples were collected at baseline and at three and four visits for CD4 and plasma HIV-1 RNA measurements, respectively.

RESULTS

Before HAART, 72% of women had detectable genital HIV-1 RNA. After 18 weeks on HAART, only one woman (2.5%) had detectable plasma HIV-1 RNA and two women (5.1%) had detectable genital HIV-1 RNA. Similar results were observed at each follow-up visit. However, 16/34 (47%) women with consistently undetectable plasma HIV-1 RNA shed HIV-1 at least once between weeks 18 and 28. In samples with detectable genital HIV-1, the mean quantity of HIV-1 RNA decreased from 3.87 prior to HAART to 3.04 log(10) copies/mL at last visit (median 29 weeks; a 6.8-fold decrease in absolute number of copies/mL) (p = 0.04). A significant median CD4 lymphocyte cell gain of 121 cells/muL (interquartile range 59 to 204) was measured between pre-HAART and last visit.

CONCLUSION

These findings suggest that HAART could play a role in reducing HIV transmission in Africa; however, they underscore the need to emphasise safe sex practices with patients taking HAART.

[Cryptococcal meningitis in HIV-infected patients at Bobo-Dioulasso hospital (Burkina Faso)]

Cryptococcus neoformans is an important fungal pathogen in immunocompromised patients. A retrospective study was conducted to investigate the occurrence of Cryptococcus neoformans infection in patients admitted to Bobo-Dioulasso Hospital over a 3 year-period. During this period, cryptococcal meningo-encephalitis was diagnosed in 36 individuals. The median age of the patients under study was 34.25 years. There was a male preponderance (24 males/12 females) in our report. Typical presentations were persistent headaches (27 cases/36), neck stiffness (16/36), altered consciousness (14/36), fever (12/36) and convulsions (9/36). Oral candidiasis coexisted with cryptococcal meningitis in 7 patients. HIV serology was positive in all patients. At diagnosis, lymphocytes counts were < 1500/mm3 in 66.66% patients. CSF examination with India ink helped to the diagnosis of cryptococcosis in all cases. Cryptococcus neoformans was associated with Streptococcus pneumoniae in 4 patients. 15/36 patients died within 1 to 29 days after admission. High mortality was related to delayed diagnosis. Cryptococcal meningitis highly contributes to mortality in HIV-infected patients in Burkina Faso and it may occur in patients not severely immunocompromised patients. A need exists to improve strategies for clinical management of AIDS patients in poor African countries.
