IntroductionAmerican tegumentary leishmaniasis (ATL) can affect the skin or mucosa (mucocutaneous leishmaniasis – MCL) including the oral cavity. MCL oral lesions are often confused with other oral diseases, delaying diagnosis and specific treatment, and increasing the likelihood of sequelae. Thus, increasing the knowledge of the evolution of ATL oral lesions can facilitate its early diagnosis improving the prognosis of healing.ObjectivesEvaluate the frequency of ATL oral lesion and describe its clinical, laboratory and therapeutic peculiarities.MethodsA descriptive transversal study was carried out, using data from medical records of 206 patients with MCL examined at the outpatient clinics-IPEC-Fiocruz between 1989 and 2013. Proportions were calculated for the categorical variables and the association among them was assessed by the Pearson's chi-square test. Measures of central tendency and dispersion were used for the continuous variables and their differences were assessed by both parametric (t test) and non parametric (Mann-Whitney) tests. P-values <0.05 were considered as significant.ResultsThe most affected site was the nose, followed by the mouth, pharynx and larynx. Seventy eight (37.9%) have oral lesions and the disease presented a lower median of the evolution time than in other mucous sites as well as an increased time to heal. The presence of oral lesion was associated with: the presence of lesions in the other three mucosal sites; a smaller median of the leishmanin skin test values; a longer healing time of the mucosal lesions; a higher recurrence frequency; and a smaller frequency of treatment finishing and healing. When the oral lesion was isolated, it was associated with an age 20 years lower than when the oral lesion was associated with other mucosal sites.ConclusionConsidering the worst therapy results associated with the presence of oral lesions, we suggest that lesions in this location represent a factor of worse prognosis for MCL.
Background Sporotrichosis is a subcutaneous or implantation mycosis caused by some species of the genus Sporothrix. Rio de Janeiro state, Brazil, experiences hyperendemic levels of zoonotic sporotrichosis, with increasing cases of disseminated disease, especially in people living with HIV (PLHIV). Involvement of the nasal mucosa is rare and occurs isolated or in disseminated cases, with a delayed resolution. Methodology/Principal findings This study aimed to describe the epidemiological, clinical, and therapeutic profiles of 37 cases of sporotrichosis with involvement of the nasal mucosa treated at the ear, nose, and throat (ENT) outpatient clinic of the Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz, from 1998 to 2020. Data were reviewed from the medical records and stored in a database. The Mann–Whitney test was used to compare the means of quantitative variables, and Pearson chi-square and Fisher’s exact tests were used to verify the association between qualitative variables (p<0.05). Most patients were males, students or retirees, with a median age of 38 years, residents in the municipality of Rio de Janeiro, and infected through zoonotic transmission. Disseminated sporotrichosis forms in patients with comorbidities (mostly PLHIV) were more common than the isolated involvement of the mucosa. The main characteristics of lesions in the nasal mucosa were the presence/elimination of crusts, involvement of various structures, mixed appearance, and severe intensity. Due to therapeutic difficulty, itraconazole was combined with amphotericin B and/or terbinafine in most cases. Of the 37 patients, 24 (64.9%) healed, with a median of 61 weeks of treatment, 9 lost follow-up, 2 were still treating and 2 died. Conclusions Immunosuppression was determinant to the outcome, with worse prognosis and lower probability of cure. Notably in this group, the systematization of the ENT examination for early identification of lesions is recommended to optimize the treatment and outcome of the disease.
A Paracoccidioidomicose (PCM) é uma micose profunda sistêmica causada por um fungo dimorfo, de aspecto microscópico similar a roda de leme de navio, o Paracoccidioides brasiliensis (Pb). A PCM apresenta distribuição geográfica restrita ao continente americano, acomete sobretudo indivíduos do sexo masculino, sem predileção por raça. Seu quadro clínico é bastante variado. OBJETIVO: Realizar análise epidemiológica de 26 casos de PCM avaliados no Setor de Otorrinolaringologia da Fundação Oswaldo Cruz - FIOCRUZ. FORMA DE ESTUDO: Clínico retrospectivo. MATERIAL E MÉTODO: Estudou-se retrospectivamente 26 prontuários de pacientes com manifestações otorrinolaringológicas da PCM atendidos no período de outubro de 1998 a setembro de 2001. Avaliou-se: sexo, idade, profissão, grau de escolaridade, se etilistas e/ou tabagistas, sintomatologia, local das lesões, presença de co-infecção, exames complementares realizados e opção terapêutica. RESULTADOS: 23 (88,5%) pacientes eram do sexo masculino e 3 (11,5%) do sexo feminino, com idade entre 32 e 72 anos. 11 (42,3%) pacientes eram agricultores e 21 (80,8%) tabagistas e/ou etilistas. Os locais mais comumente atingidos foram a epiglote e a parede nasal lateral. Utilizaram-se derivados sulfamídicos para o tratamento de 14 (53,9%) pacientes e imidazólicos em 12 (46,1%) casos. DISCUSSÃO: Lesões pulmonares podem ser confundidas com tuberculose, devido a suas semelhanças clínicas e radiográficas. A desnutrição pode predispor quadros clínicos de extrema gravidade. CONCLUSÃO: A anamnese detalhada dos pacientes portadores de PCM revela importantes aspectos, como procedência e hábitos pessoais. A atuação interdisciplinar, sobretudo de médicos e dentistas, colabora para um precoce diagnóstico e adequado acompanhamento do doente.
