Objective:The main goal of this work was to produce a review of educational strategies to prevent diabetes, hypertension, and obesity. Method: PubMed database was consulted using combined descriptors such as [Prevention] Results: A total of 8,908 articles were found, of which 1,539 were selected about diabetes mellitus (DM, n=369), arterial systemic hypertension (ASH, n=200), and obesity (OBES, n=970). The number of free full text articles available was 1,075 (DM = 276, ASH = 118 and OBES = 681). In most of these studies, demographic characteristics such as gender and age were randomized, and the population mainly composed by students, ethnic groups, family members, pregnant, health or education professionals, patients with chronic diseases (DM, ASH, OBES) or other comorbidities. Group dynamics, physical activity practices, nutritional education, questionnaires, interviews, employment of new technologies, people training and workshops were the main intervention strategies used. Conclusion:The most efficient interventions occurred at community level, whenever the intervention was permanent or maintained for long periods, and relied on the continuous education of community health workers that had a constant interference inside the population covered. Many studies focused their actions in children and adolescents, especially on students, because they were more influenced by educational activities of prevention, and the knowledge acquired by them would spread more easily to their family and to society.

Fonsecaea pedrosoi is an important causative agent of chromoblastomycosis (CBM) especially in humid areas of the world; however, little is known about the infective forms of this agent that cause CBM. The aim of this study was to investigate the murine tissue response to inoculation with different forms of F. pedrosoi and the morphological changes of the fungal cells in vivo. BALB/c mice were inoculated intraperitoneally with hyphae, conidia or conidiogenous cells and conidia (CCC) at a single site. In addition, the abdomen and footpads were infected subcutaneously with CCC. Fungal forms were inoculated at a final concentration of 1 × 10(6) cells. Hyphae and ungerminated conidia inocula could not be transformed into parasitic forms. In tissue, a great number of conidiogenous cells underwent transformation into sclerotic bodies, which were more resistant to phagocytes in vivo than conidia and hyphae. Clinical and mycological cure of animals infected with CCC was observed from the fourth to the sixth week of infection, while conidia and hyphae infections were faster and generally lasted 2 to 3 weeks. A high number of destructed conidia was observed intracellularly in macrophages. The migration of neutrophils to the inflammatory site seems important for microbicidal activity, particularly against hyphae. Our observations suggest that inocula with conidiogenous cells are associated with in vivo transformation into sclerotic bodies and that local immune response involved with host resistance to experimental F. pedrosoi-infection is primarily mediated by neutrophils as observed in histological sections.

BACKGROUD: Endoscopes are routinely used in hospitals and clinics of the world and they can be potential sources of cross-infection when the decontamination process is unsuitable AIM: The routines of flexible endoscope (bronchoscopes, esophagogastroduodenoscopes and colonoscopes) disinfection procedures used in two Brazilian university hospitals were evaluated during a 3-year period METHODS: Aleatory samples from internal channels of endoscopes were collected after patient examination and after cleaning/disinfection procedures RESULTS: A contamination >3 log10 was achieved in samples recovered from endoscopes after patient examination. These samples yielded gram-negative bacilli (n = 142: 56%), gram-positive cocci (n = 43: 17%), yeast cells (n = 43: 17%), and gram-positive bacilli (n = 26: 10%). Approximately, 72 out of 149 samples (48.32%) collected after undergoing the cleaning and disinfection procedures disclosed gram-negative bacilli (n = 55: 61%), gram-positive cocci (n = 21: 23%), gram-positive bacilli (n = 8: 9%) and yeast cells (n = 6: 7%). Esophagogastroduodenoscopes and colonoscopes were the most frequently contaminated devices. Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Enterobacter spp, Serratia marcescens, Proteus mirabilis, Citrobacter freundii, Staphylococcus aureus, Staphylococcus coagulase negative, Micrococcus luteus, Candida albicans, C. tropicalis, C. glabrata, C. guilliermondii, Bacillus spp and Corynebacterium spp were predominantly identified CONCLUSION: Inappropriate cleaning and low times of disinfection were respectively the major factors associated with the presence of microorganisms in colonoscopes and esophagogastroduodenoscopes. By analyzing the identified germs, hospital disinfection was considered of either intermediate or poor level. After this investigation, both university centers improved their previous protocols for disinfection and conditions for reprocessing endoscopes.

Correlação entre os resultados laboratoriais e os sinais e sintomas clínicos das pacientes com candidíase vulvovaginal e relevância dos parceiros sexuais na manutenção da infecção em São Paulo, Brasil Abstract PURPOSE: to relate yeasts identifi ed by laboratory tests to clinical signs and symptoms in patients with vulvovaginal candidiasis, and to investigate the importance of the sexual partners in the recurrence of the infection. METHODS: from July 2001 to July 2003, a sample of 179 patients aged from 18 to 65 years old, with clinical suspicion of fungal vaginitis were analyzed in a prospective study in Great São Paulo. Exclusion criteria included: pregnancy, impaired intrinsic or extrinsic immune response (including Aids), diabetes or immunosuppression; patients undergoing corticosteroid, antibiotic or hormone therapy, in post menopause, with intrauterine device (IUD) or making use of vaginal douches or spemicides. Samples of vaginal and penis secretions from partners of patients with relapse of vaginitis episodes were collected for microscopy and fungal culture. Fungal colonies isolated in CHROMagar Candida were identifi ed by classical methods. Fisher's exact t-test was used to correlate the clinical picture with the yeasts isolated from patients. RESULTS: the most relevant clinical signs and symptoms were pruritus and vaginal discharge followed by erythema and edema, statistically independent from the etiological agent. Direct microscopy revealed yeasts in 77 patients with vulvovaginitis, and 40 Candida spp cultures were obtained. Candida albicans (70%), C. glabrata (20%), C. tropicalis (7,5%) and C. guilliermondii (2,5%) were identifi ed. The yeasts prevalent in partners were C. albicans and C. glabrata. The same species were detected in

We report a case of tinea on the eyelid in a woman with psoriasis. Due to the history of psoriasis and clinical aspect of the lesion the diagnosis of psoriasis was suggested in the first place; however, laboratory examination revealed Microsporum gypseum. The patient was treated with oral itraconazole resulting in clinical and mycological cure. We emphasize the uncommon location of tinea caused by M. gypseum and the importance of searching for fungal infection on scaly lesions.

A strategy using bacilli was adopted aiming to investigate the mitigation of the effects of water deficit in sesame. An experiment was carried out in a greenhouse with 2 sesame cultivars (BRS Seda and BRS Anahí) and 4 inoculants (pant001, ESA 13, ESA 402, and ESA 441). On the 30th day of the cycle, irrigation was suspended for eight days, and the plants were subjected to physiological analysis using an infrared gas analyzer (IRGA). On the 8th day of water suspension, leaves were collected for analysis: superoxide dismutase, catalase, ascorbate peroxidase, proline, nitrogen, chlorophyll, and carotenoids. At the end of the crop cycle, data on biomass and vegetative growth characteristics were collected. Data were submitted for variance analysis and comparison of means by the Tukey and Shapiro–Wilk tests. A positive effect of inoculants was observed for all characteristics evaluated, contributing to improvements in plant physiology, induction of biochemical responses, vegetative development, and productivity. ESA 13 established better interaction with the BRS Anahí cultivar and ESA 402 with BRS Seda, with an increase of 49% and 34%, respectively, for the mass of one thousand seeds. Thus, biological indicators are identified regarding the potential of inoculants for application in sesame cultivation.
