ABSTRACT

Background: Syphilis is a sexually transmitted disease caused by Treponema pallidum. However, there are of hematogenic and vertical transmission. All health care professionals must be aware of the manifestations of this condition, such as oral lesions. Objectives: This study to analyze and compare four clinical cases of syphilis that were diagnosed based on lesions in the oral cavity with published literature. Material and Methods: Four patients with a confirmed sorologic and clinical diagnosis of syphilis were examined, confirmated from manifestation of oral lesions together with analysis of serological laboratory tests and histopathological analyses. Results: Lesions were found in classic sites such as lips, tongue and skin. However, there were also lesions on the hard palate, and labial commissure, which correspond to less than 5% of the syphilis oral manifestations. Conclusions: The practice of unprotected oral sex may result in infection and development of syphilis. The acknowledgment of the oral manifestations of syphilis in all its period of training for health professionals is of basic importance, the association of clinical features, histopathological findings and serological tests are required to complete the diagnosis and correct treatment (AU)

ABSTRACT

Aim: To measure the agreement of methods for identification of Candida species in oral cavity samples, comparing the CHROMagar Candida, microculture, API 20C AUX and RAPD techniques. Methods: Ninety-one colonies of Candida were isolated and presumptively identified in CHROMagar Candida, submitted to microculture, API 20C AUX and RAPD techniques. After this, agreement among methods using Kappa test was performed. Results: Agreement rates between RAPD and CHROMagar Candida, showed significant accuracy for C. albicans, C. tropicalis, C. dubliniensis and C. krusei (Kappa: 0.760, 0.640, 0.416 and 0.360, respectively, p<0.05). Comparing RAPD results with microculture, the highest agreement was for C. albicans (Kappa: 0.851 - p<0.05) but no significant agreement for C. lusitaniae, C. krusei and C. guilliermondii was obtained (p>0.05). The agreement was significant for all identified species when RAPD (OPE-18) and API 20C AUX (p<0.05) were used. Critical levels of agreement between RAPD and microculture were observed when C. lusitaniae, C. krusei and C. guilliermondii were identified.

ABSTRACT

This study aimed to evaluate the in vitro antifungal susceptibility of Candida species of head-and-neck-irradiated patients (Group 1), non-institutionalized (Group 2) and institutionalized elders (Group 3) using Etest® methodology. Candida was isolated from saliva and presumptively identified by CHROMagar Candida(r), confirmed by morphological criteria, carbohydrate assimilation (API 20C AUX®) and genetic typing (OPE 18). The collection was made from 29, 34 and 29 individuals (Groups 1, 2 and 3, respectively) with 67 isolates. Etest® strips (ketoconazole, itraconazole, fluconazole, amphotericin B and flucytosine) on RPMI (Roswell Park Memorial Institute) agar, on duplicate, were used to evaluate susceptibility. ATTC (American Type Culture Collection) 10231 (Candida albicans) was used as quality control. Among the 67 isolates of Candida species, most were susceptible to azoles, flucytosine and amphotericin B. None of the isolates showed resistance and dose-dependent susceptibility to amphotericin B. There were nine strains resistant to itraconazole, six to fluconazole and two to ketoconazole and ten dose-dependent, mainly to flucytocine. The highest MIC (minimum inhibitory concentration) to C. albicans, C. tropicalis, C. parapsilosis was 2.671 µg.mL-1, 8.104 µg.mL-1, 4.429 µg.mL-1, all for flucytosine. C. krusei and C. glabrata were associated with higher MIC for azoles and C. glabrata with higher MIC to flucytosine. In summary, susceptibility to all tested antifungal agents was evident. The isolates were more resistant to itraconazole and dose-dependent to flucytosine. A comparison of C. albicans in the three groups showed no outliers. Higher MIC was associated with C. krusei and C. glabrata.

Esse estudo objetivou avaliar a susceptibilidade antifúngica in vitro de espécies de Candida obtidas de pacientes irradiados em cabeça e pescoço (Grupo 1), idosos não institucionalizados (Grupo 2) e idosos institucionalizados (Grupo 3) usando a metodologia Etest(r). Candida foi isolada da saliva e identificada presuntivamente pelo teste CHROMagar Candida(r), confirmada pelo critério morfológico, assimilação de carboidratos API 20C AUX(r) e identificação genética (OPE 18). A coleta foi feita em 29, 34 e 29 indivíduos (Grupos 1, 2 and 3, respectivamente) com 67 isolados. As fitas de Etest(r) (cetoconazol, itraconazol, fluconazol, anfotericina B and flucitosina) em meio ágar RPMI (Roswell Park Memorial Institute), em duplicata, foram utilizados para avaliar a susceptibilidade. A ATTC (American Type Culture Collection) 10231 (Candida albicans) foi usada como controle de qualidade. Dos 67 isolados de espécies de Candida, a maioria foi susceptíveis aos azoles, flucitosina e anfotericina B. Nenhum dos isolados mostrou resistência ou susceptibilidade dose-dependente a anfotericina B. Houve nove espécies resistentes ao itraconazol, seis ao fluconazol e duas ao cetoconazol e dez dose-dependentes, principalmente a flucitosina. Os maiores valores de MIC (mínima concentração inibitória) para C. albicans, C. tropicalis, C. parapsilosis foram, respectivamente, 2,671 μg.mL-1, 8,104 μg.mL-1, 4, 429 μg.mL-1, todos para a flucitosina. C. krusei e C. glabrata foram associadas a um maior MIC para azoles e C. glabrata com maior MIC para flucitosina. Em resumo, a susceptibilidade a todos os antifúngicos testados foi evidente. Os isolados foram mais resistentes ao itraconazol e dose dependentes para a flucitosina. A comparação para C. albicans nos três grupos não mostrou diferença. Os maiores valores de MIC estavam relacionados a C. krusei e C. glabrata.

ABSTRACT

UNLABELLED: Patients with head and neck cancer have to deal with the impact of treatment on its functional and aesthetic aspects, and its self-report enables improvements in clinical and social support. OBJECTIVE: To evaluate the quality of life of patients dealing with squamous cell carcinoma of the head and neck. METHOD: A prospective analytical study. Twenty nine patients with mean age of 57 years answered at three stages: onset, middle and end of treatment, the questionnaires: Quality of Life Core Questionnaire - Cancer 30 and the Quality of Life Questionnaire - Head and Neck, the European Organization for Research and Treatment of Cancer. We used the Friedman test at: 0.05. RESULTS: There were high mean values concerning physical, cognitive, social functions; improvements in general health and social function decline during treatment; and a significant difference in taste and smell (p = 0.020), swallowing (p = 0.040), cough (p = 0.013) and weight loss (p = 0.011). CONCLUSION: There was a significant reduction in the quality of life for some common symptoms resulting from cancer treatment, which was not seen in the evaluation of the aspects related to physical, cognitive and social functions, and general health.

ABSTRACT

Pacientes com câncer em cabeça e pescoço têm de lidar com o impacto de seu tratamento sobre aspectos funcionais e estéticos e seu autorrelato permite aprimorar medidas de suporte clínico e social. OBJETIVO: Avaliar a qualidade de vida de pacientes em tratamento de carcinoma de células escamosas em cabeça e pescoço. MÉTODO: Estudo analítico prospectivo. Vinte e nove pacientes com idade média de 57 anos responderam em três momentos: início, metade e final do tratamento, aos questionários: Quality of Life Core Questionnaire - Cancer 30 e ao Quality of Life Questionnaire - Head and Neck, European Organization for the Research and Treatment of Cancer. Foi realizado teste de Friedman, significância: 0,05. RESULTADO: Houve altas médias para as funções física, cognitiva, social; melhora no estado de saúde geral e declínio da função social ao longo do tratamento e diferença significativa para gosto e cheiro (p = 0,020), deglutição (p = 0,040), tosse (p = 0,013), e perda de peso (p = 0,011). CONCLUSÃO: Houve redução significativa da qualidade de vida em relação a alguns sintomas comuns decorrentes do tratamento do câncer, que não ocorreu na avaliação das dimensões relacionadas às funções física, cognitiva, social e ao estado geral de saúde.
