Abstract: background: dermatomycoses caused by emergent fungi are rare clinical entities, except in onychomycosis. as certain fungi and yeasts can be resident in the skin, the positivity in cultures of ungual samples should be interpreted in accordance with respective clinical data, direct exams of the samples, quantification of isolated colonies in relation to the inoculation points and persistent positivity after multiple cultures. the invasion of fingernails by nondermatophytic fungi (ndf) is rare and in various studies the prevalence ranges from 1.45% to 17.6%. objetives: the objectives of this work were to describe the occurrence and underscore the importance of emergent fungi as causes of onychomycosis. methods: the finger and toenails of patients presenting at dermatologists' consulting rooms were examined. whenever there was clinical suspicion of onychomycosis, nail samples were obtained for mycological examination at a central laboratory. results: in this study, 400 of 2271 patients with onychomycosis were followed-up, 264 and 136 with involvement of the toenails and fingernails, respectively. the etiological agent was confirmed by means of a direct mycological exam and growth in culture. in the present work, yeasts of the candida genus (49%) were detected as the most frequent etiological agents of fingernail onychomycosis, occurring more often in women. in contrast, the dermatophytes were the most frequent pathogen in toenails, in 186 patients (46.5%). onychomycosis by emergent fungi represented 4.5% of all nail infections. conclusion: the authors consider that a correct diagnosis of the etiological agent of non-dermatophytic onychomycosis should follow certain criteria, among which the positivity of direct exam, in the culture and its confirmation by means of repeated exams.

Abstract: FUNDAMENTOS: A infec o por dermatófitos afeta aproximadamente 40% da popula o mundial, representa 30% de todas as infec es micóticas cutaneas, e a onicomicose por dermatófito é a mais freqüente, representando entre 18 e 40% de todas as onicopatias. A onicomicose é causada primariamente por dermatófitos, Candida spp. e outros fungos n o dermatófitos. Entre os agentes fúngicos, os dermatófitos, particularmente Trichophyton rubrum, s o os mais comuns desses patógenos. Atualmente, Candida spp. pode invadir a unha distal e proximal. As onicomicoses provocadas por fungos n o dermatófitos vêm aumentando em sua prevalência, e, pela similaridade clínica com a onicomicose por dermatófito, é necessário o diagnóstico laboratorial para sua diferencia o. OBJETIVOS: O objetivo do presente trabalho é avaliar a ocorrência de onicomicose na cidade do Rio de Janeiro. MéTODOS: Foram avaliados 2.920 pacientes entre janeiro de 1998 e dezembro de 1999, dos quais 1.416 apresentaram anormalidades nas unhas. RESULTADOS: A confirma o micológica de onicomicose foi possível em 565 dos 2.920 pacientes, e a prevalência estimada pontual na cidade do Rio de Janeiro é 19,34%. Os homens foram responsáveis por 34,16% das onicomicoses, e as mulheres por 65,84%. A distribui o por agente etiológico dos 224 pacientes com onicomicose que apresentaram cultura positiva foi: dermatófitos 64,7%, Candida spp. 30,1% e outros n o dermatófitos 5,2%. CONCLUS O: A microbiota fúngica é completamente trocada no mundo periodicamente em sua composi o quantitativa e qualitativa, sendo afetada por vários fatores ambientais. Assim, o exame periódico da composi o desta microbiota vem a ser vantajoso e de importancia epidemiológica e terapêutica.

Abstract: FUNDAMENTOS: As dermatomicoses causadas por fungos emergentes s o entidades clínicas raras, à exce o das onicomicoses. Como certos fungos e leveduras podem residir na pele, a positividade em culturas de escamas ungueais deve ser interpretada obrigatoriamente em concordancia com os respectivos dados clínicos, exames diretos das amostras, quantifica o das col nias isoladas em rela o aos pontos de inocula o e, principalmente, deve a positividade ser mantida após a repeti o dos cultivos. A invas o da unha por fungos n o dermatofíticos (nondermatophytic molds, NDM) em diferentes estudos varia de 1,45% a 17,6%. OBJETIVOS: Os objetivos do trabalho s o mostrar a ocorrência e real ar a importancia dos fungos emergentes como causadores de onicomicose. MéTODOS: As unhas dos pacientes atendidos nos consultórios dos dermatologistas foram examinadas, e, caso houvesse suspeita clínica de onicomicose, coletavam-se amostras que eram enviadas para exame micológico no laboratório. RESULTADOS: Neste estudo, foram avaliados 2.271 pacientes e diagnosticada onicomicose em 400 deles, sendo 264 com acometimento das unhas do pé, e 136 das unhas da m o. O agente etiológico foi confirmado pelo exame micológico direto e crescimento em cultura. A onicomicose por fungos emergentes representou 4,5% de todas as infec es de unha. Foram detectadas as leveduras do gênero Candida (49%) como agentes etiológicos mais freqüentes de onicomicoses nas unhas das m os e em mulheres. Em contraste, os dermatófitos foram os mais freqüentes de todas as onicomicoses dos pés, no total de 186 (46,5%). CONCLUS O: Ao contrário da rotina diagnóstica hoje utilizada, concluiu-se que o diagnóstico correto do agente etiológico da onicomicose n o dermatofítica deve obedecer a determinados critérios, dos quais se destaca o conjunto formado pela positividade no exame direto, na cultura, com comprova o na repeti o do exame.

Abstract: The sexual and reproductive health program, in Florianópolis/SC, promoted work-shops, mounted and performed by medical students, in public elementary schools. After that, it was possible to investigate the students’ opinion with a transverse quantitative study. 333 school children aged from 11 to 16 and enrolled between 5th and 9th grades answered the questionnaire. In the sample, 15.9% had initiated sexual activity, and 38.8% of them did not use condoms every time. The young people who have not started sexual activities talk about sexuality with their parents in greater proportion than those who have already started (significant difference). The students’ evaluation about the project was positive. It is expected to raise interest in new strategies for sex education permanently in public elementary schools, with the support of higher education institutions and strengthening the participation of parents and caretakers, in the process.

Abstract:

During July to November of 2008, the artisanal fisheries captured juvenile sharks belonging to the Carcharhinus and Sphyrnidae family in the Veracruz Reef System (south western Gulf of Mexico). The three most abundant organisms were of the species Sphyrna lewini, Carcharhinus brevipinna and Rhizoprionodon terraenovae. Local fisherman recognized five captured areas of sharks as a direct way or bycatch. Some of these areas are located near to eddies formations and river discharges (high productivity areas). These top predators fed on benthic and demersal prey of coastal and reef habits had been the Teleost group the most important item in its diet. However it is possible to observe differences in its feeding tendency.

Echocardiographic predictors of early in-hospital heart failure during first ST-elevation acute myocardial infarction: does myocardial performance index and left atrial volume improve diagnosis over conventional parameters of left ventricular function?

Abstract: Echocardiography was performed within 30 hours of chest pain in 95 patients with a first ST-elevation AMI followed during the first week of hospitalization. Several clinical and echocardiographic variables were analyzed. CHF was defined as Killip class ≥ II. Multivariate regression analysis was used to select independent predictor of in-hospital CHF.Early in-hospital CHF occurred in 29 (31%) of patients. LVEF ≤ 0.45 was the single independent and highly significant predictor of early CHF among other clinical and echocardiographic variables (odds ratio 17.0; [95% CI 4.1 - 70.8]; p < 0.0001). MPI alone could not predict CHF in first ST-elevation AMI patients. Left atrial volume was not associated with early CHF in such patients.For patients with first, isolated ST-elevation AMI, LVEF assessed by echocardiography still constitutes a strong and accurate independent predictor of early in-hospital CHF, superior to isolated MPI and left atrial volume in this particular subset of patients.Early detection of patients with acute myocardial infarction (AMI) at risk of development of in-hospital congestive heart failure (CHF) is necessary to limit myocardial injury and left ventricular (LV) dysfunction. Non-invasive evaluation of LV function has been assessed by systolic as well diastolic echocardiographic indexes and related to short-term clinical outcome [1-8].An increasing number of studies has reported the use of a combined index integrating systolic and diastolic LV function, the overall myocardial performance index (MPI)[9], for predicting short-term adverse outcome in AMI [10-14]. However, some included high-risk patients with multiple myocardial infarction [10,13] and previous history of CHF [13] or with non-ST elevation [10-13], while others studied only anteroseptal AMI [14], that could affect their results. Moreover, some authors [11,13,14] considered diverse in-hospital complications besides CHF (recurrent angina, reinfarction, death, arrhythmias, heart block, cardi
