Epidemiologia de candidíase hospitalar: Importância da identificação específica

Nosocomial infections with Candida species are recognized as a significant cause of morbidity and mortality in both seriously ill immunocompetent and immunocompromised patients. Infections with Candida albicans and non-albicans Candida species have become a significant cause of infection in humans. Several of the more commonly Candida spp isolates are less susceptible to the antifungal drugs currentlly applied in clinical treatment, a factor that means significant difficulties for effective treatment. The modern mycology laboratory has an important role to play in several aspects relating to these organisms, including therapy, detection, identification and epidemiological analysis. In this study, we have provided an initial comparison of differences in species distribution among Candida isolates from four general hospitals of São Paulo,SP. Overall, 40 isolates of C. albicans, C. parapsilosis and C. tropicalis were isolated respectively in 35%, 50% and 15%, revealed a tendency of higher frequency of non-albicans species. The species distribution in patients with candidemia showed that the most commonly species were C. parapsilosis (45,4%), followed by C. albicans (36,4%) and C. tropicalis (18,2%); thus, we have an increase of non-albicans species. The three different species were include in 6, 3, and 4 different biotypes, respectively C. albicans, C. parapsilosis e C. tropicalis. This study emphasizes the importance of periodic evaluation of Candida species distribution especially in centers caring for patients at risk.

Epidemiologia das dermatofitoses em instituições públicas da região de Araraquara - SP

Dermatophytosis on skin, hair and nails are the most common infectious process in the world. A total of 94 individuals from Public Institutions from the city of Araraquara - Sao Paulo/Brazil, with suspected of dermatophytic lesions were examined in order to determine the incidence and etiology of dermatophytosis. 105 specimens were collected from August to December of 2001 in the Mycology Laboratory of the Faculdade de Ciências Farmacêuticas. It was observed that 47 samples were positive for dermatophytes. Trichophyton rubrum was the prevalent specie (59.6%), followed by Microsporum canis (17%), T. tonsurans (10.6%), T. mentagrophytes (8.5%) and Epidermophyton floccosum (4.3%). T. rubrum was the most frequent in interdigital lesions (81.5%) and M. canis was the main dermatophyte involved in scalp lesions (58.3%). Therefore, it was observed a predominance of antropophilic and zoophilic species, respectively. These results are in agreement with statistical data from South and Southeast regions of Brazil, as well as from other parts of the world in which these fungi were the most frequently isolates from tinea pedis and tinea capitis. In this study, it was also observed a high percentage of T. tonsurans (41.7%) in tinea capitis and this result was different from the statistical data collected until now in our region.

Tuberculose e o estudo molecular da sua epidemiologia

Systems that can distinguish epidemiologically-related Mycobacterium tuberculosis strains from unrelated ones are extremely valuable. Molecular biology techniques have allowed a great deal of information to be acquired about the infectious disease tuberculosis (TB) that was very hard or impossible to obtain by conventional epidemiology. A typing method based on bacterial DNA genome differences, known as RFLP (restriction fragment length polymorphism), is widely used to discriminate strains in the epidemiologic study of TB. However, RFLP is laborious and there is a tendency to replace it by other methods. Thus, other DNA sequences have been employed as epidemiological markers, as in Spoligotyping, a fast technique based on PCR followed by differential hybridization of amplified products. The polymorphism observed among different isolates is probably the product of strain-dependent recombination. MIRU (mycobacterial interspersed repetitive unit) typing is a reproducible and fast assay, involving the generation of genotypes based on the study of 12 loci containing VNTRs (variable-number tandem repeats) in strains of the M. tuberculosis complex. It compares strains from different geographic areas and allows the movement of individual lineages to be tracked, as in RFLP. This approach enables a greater number of isolates to be analyzed, leading to the identification of a larger number of foci of transmission within the population and thus to improved ways of slowing the progress of the disease.

Epidemiologia do Padrão Face Longa em escolares do Ensino Fundamental do município de Bauru - SP

OBJECTIVE: This study aimed to classify and determine the prevalence of individuals with vertical alteration of facial relationships, according to the severity of discrepancy, especially individuals with long face pattern. METHODS: The sample was composed of 5,020 individuals of Brazilian nationality, of both genders, aged 10 years to 16 years and 11 months, attending fundamental schools at the city of Bauru-SP. Examination of facial morphology comprised direct observation of the face in frontal and lateral views, always with the lips at rest, aiming to identify the individuals presenting vertical alteration of facial relationships. After identification, these individuals were scored, according to severity, into three subtypes, namely mild, moderate and severe. The prevalence of individuals with long face pattern considered only the individuals scored as subtypes moderate and severe. RESULTS: There was prevalence of 34.94% of vertical alteration of facial relationships and 14.06% of long face pattern. CONCLUSIONS: The results obtained in this study revealed that the prevalence of vertical alteration of facial relationships and long face pattern was higher than reported in the literature.
