“…The persistence of environmental trigger such as heat or humidity might explain frequent recurrences. Conversely, no case of lobomycosis was described in our population, though this fungal infection has already been reported in French Guiana, 10,11 as in the Amerindian populations of Colombia 12 and Brazil 13 . The role of dolphins as hosts of Lacazia loboi has been recently discarded, 14 and its parasitic cycle remains unclear.…”

Spectrum of skin diseases in Amerindian villages of the Upper Oyapock, French Guiana

et al. 2020

Background Due to their genetic characteristics, their isolation in rainforest areas, and their traditional way of life, Amerindian populations are likely to suffer from a specific spectrum of dermatoses. However, there are few available data on such skin disorders. Our aims were to describe all skin disorders in two Amerindian villages of French Guiana. Methods This retrospective study concerned all patients who consulted in the HealthCentres of Camopi and Trois-Sauts between July 1, 2017, and December 31, 2018. We included all patients classified with an ICD code linked to a skin disorder. All medical records were cross-checked by two dermatologists to correct misclassifications.Results A total of 639 patients formed the study population, for 866 different skin disorders. Non-sexually transmitted infections represented 57.6% of all skin disorders, followed by eczema (11.5%) and bites/envenomations (9.1%). Bacteria were responsible for 238 skin infections, followed by fungi (141 cases) and parasites (69 cases, including 43 scabies, nine cutaneous leishmaniasis, and two tungiasis). We reported a low prevalence of sexually transmitted infections (10 cases) and an absence of skin cancers. ConclusionsThis study revealed the absence of skin cancer in the Amerindian population of the Upper Oyapock and the important burden of infectious and animal-related diseases. Future studies should assess a possible underestimation of sexually transmitted diseases in this area. Public health policies should target neglected diseases such as cutaneous leishmaniasis, tungiasis, scabies, and envenomations. Atopic dermatitis was a significant and unexpected cause of consultations. Dermatological conditions in the Amerindian villages of French Guiana have never been described. About 12,000 Amerindians live in this territory, divided into six different ethnic groups. Many of them live in cities where ethnic diversity makes their study difficult, and the selection of patients according to ª

Spectrum of skin diseases in Maroon villages of the Maroni area, French Guiana

et al. 2022

Background Due to their genetic characteristics and their high exposure to infectious diseases, Maroons are likely to suffer from a specific spectrum of skin diseases. However, skin disorders have never been explored in this population. We aimed to describe all skin diseases in Maroon villages of the Maroni region in French Guiana. Methods This retrospective study concerned all patients who consulted in the remote health centers of Apatou, Grand‐Santi, Papaichton, and Maripasoula between October 5, 2017, and June 30, 2020. We included all patients registered with a skin disorder (International Classification of Diseases) in the medical database. We excluded patients whose diagnosis was invalidated after cross‐checking by a dermatologist. Results A total of 4741 patients presented at least one skin disease, for 6058 different disorders. Nonsexually transmitted infections represented 71.6% of all diagnoses, followed by inflammatory diseases (9.8%) and bites/envenomations (4.6%). The three most frequent conditions were scabies, abscesses, and impetigo. Besides scabies, neglected tropical diseases (NTDs) were still prevalent as we reported 13 cases of leprosy and 63 cutaneous leishmaniasis. Atopic dermatitis (AD) represented only 2.5% of our diagnoses. Conclusions With the exception of AD, which was less frequent among Maroons, these results are similar to those previously reported in Amerindians. Therefore, a common exposure to rainforest pathogens seems to induce a common spectrum of skin diseases dominated by infections. The high prevalence of NTDs requires specific public health actions.

“…No início do quadro clínico, as lesões infiltradas do tipo placa podem ser confundidas com leishmaniose cutânea; assim como as lesões com aspecto queloidal típicas da lobomicose devem ser diferenciadas daquelas da hanseníase virshowiana; e as lesões com aspecto verrucoso, vegetativo ou nodular podem levantar a suspeita de esporotricose, cromoblastomicose, paracoccidioidomicose, quelóides ou processos neoplásicos (CHEURET M, et al, 2014).…”

Lobomicose e tratamento cirúrgico: um relato de caso no interior da Amazônia

2020

View full text Add to dashboard Cite

Objetivo: Relatar um caso de Lobomicose atendido no município de Monte Alegre-Pará, interior da Amazônia. Relato de experiência: Paciente masculino, com 35 anos de idade, apresentava lesão queloidiforme em membro inferior esquerdo com 3 anos de evolução, com diagnóstico prévio de Lobomicose por exame histopatológico e tratamento anterior com criocirurgia, porém, com recidiva da lesão há um ano. Foi proposta uma nova tentativa de tratamento por exérese da lesão, sem sinais de recidiva há 18 meses. Considerações finais: Como a lobomicose é vista em áreas localizadas e, em geral, pouco desenvolvidas, há uma falha substancial de conhecimento científico em relação ao assunto; isso justifica a importância do estudo frente a esse cenário. Além disso, até o momento, na literatura, não foi apresentada terapia inteiramente eficaz contra o agente Lacazia loboi. No relato do caso, no entanto, o paciente apresentou resposta completamente satisfatória com a terapia empregada.
