Abstract: a case of dermatophytic pseudomycetoma, in a patient with a history of recurrent lesions in the scalp, for over two years, is reported. histopathological examination of the affected tissues revealed the mycelial aggregates or pseudogranules characteristic of the disease. cultures of fresh tissues samples detected a fungus identified as trichophyton tonsurans. additional examinations failed to demonstrate lesions of tinea capitis, a probable source of the deep infection. dermatophytic pseudomycetoma is an extremely rare form of dermatophytosis, and the rarity of such cases is the motive for the present communication.

Revista da Sociedade Brasileira de Medicina Tropical , 2001,
Abstract: é descrito um caso de pseudomicetoma dermatofítico, recidivante, em paciente com les es no couro cabeludo. O exame histopatológico de uma das les es mostrou, nos tecidos, os agregados micelianos ou pseudogranulos, característicos da enfermidade. Dos tecidos frescos de outras les es foi isolado o dermatófito Trichophyton tonsurans. Exames micológicos adicionais falharam em demonstrar a existência de tinea capitis, possível fonte do pseudomicetoma. A raridade dessa forma de dermatofitose profunda justifica a presente publica o.

Abstract: chromoblastomycosis (cr) is a subcutaneous chronic mycosis characterized by a granulomatous inflammatory response. however, little is known regarding the pattern of leukocyte subsets in cr and the pathways involved in their recruitment. the objective of this study was to assess the cellular subsets, chemokine, chemokine receptors and enzymes in cr. the inflammatory infiltrate was characterized by immunohistochemistry using antibodies against macrophages (cd68), langerhans'cells (s100), lymphocytes (cd3, cd4, cd8, cd45ro, cd20 and cd56) and neutrophils (cd15). the expression of mip-1a (macrophage inflammatory protein-1a), chemokine receptors (cxcr3 and ccr1) and enzymes (superoxide dismutase-sod and nitric oxide synthase-inos) was also evaluated by the same method. we observed an increase in all populations evaluated when compared with the controls. numbers of cd15+ and cd56+ were significantly lower than cd3+, cd4+, cd20+ and cd68+ cells. statistical analysis revealed an association of fungi numbers with cd3, cd45ro and inos-positive cells. furthermore, mip-1a expression was associated with cd45ro, cd68, inos and cxcr3. our results suggest a possible role of mip-1a and fungi persistence in the cell infiltration in cr sites.

Abstract: the spatial distribution, abundance, and feeding habits of termites in a sugar cane plantation in northeast brazil were studied, and based on these ecological parameters, the pest status of the species was evaluated. four species were found: amitermes nordestinus mélo & fontes, cylindrotermes nordenskioeldi holmgren, nasutitermes coxipoensis (holmgren) and syntermes nanus constantino, which we reported by the first time in association to sugar cane. the abundance and spatial distribution (vertical and horizontal) of the termites were influenced mainly by the plant root biomass and soil organic matter. c. nordenskioeldi is harmful to sugar cane, a. nordestinus is a potential pest, while n. coxipoensis and s. nanus are not potential pests. the importance of termites for maintaining the fertility, aeration and porosity of tropical soils is an evidence that basic investigations on reproduction biology and population dynamics of c. nordenskioeldi and a. nordestinus must be encouraged aiming to develop pest control agents and species-specific management techniques.

Abstract: introduction and objective: maximal inspiratory and expiratory pressures (pimax and pemax) are used to assess the integrity of respiratory muscles by measuring their strength. the aim of this study was to assess the immediate influence of hemodialysis (hd) on respiratory muscle strength by measuring pimax and pemax, investigating the integrity of that musculature and/or the presence of muscular weakness. method: a prospective, crosssectional study was carried out on a convenience sample of 35 patients with chronic kidney disease (26 men and 9 women; mean age, 51.7 ± 14.7 years) at the nephrology division of the hospital universitário alzira vellano, in the city of alfenas, in the state of minas gerais, brazil. patients had their pimax and pemax taken in the seated position (at 90°) by using a digital manovacuometer (mvd 300?) attached to a notebook for reading and recording data obtained before and after the hd session. results: both pimax and pemax were lower than the values predicted for pre- and post-hd (p < 0.0001). comparing the values obtained pre-hd and post- hd, pimax showed a slight improvement (p = 0.0420), evidenced only in patients with pre-hd values below 60 cmh2o (wilcoxon; p = 0.0480). post-hd pemax did not differ from the pre-hd measure (p = 0.4987). conclusion: the ckd patients showed a serious impairment of their respiratory muscle function, and only one isolated hd session could not significantly improve their maximum respiratory pressures. a slight improvement in the inspiratory strength was observed in patients whose pimax was lower than 60 cm-h2o before the procedure.

BIBLOS : Revista do Instituto de Ciências Humanas e da Informa??o , 2007,
Abstract: Lucien Febvre marcou sua trajetória pelo estilo de pesquisa histórica, manuseio das fontes e forma inovadora de constru o biográfica. Seu método e estilo de fazer história muito se diferenciaram da tradi o intelectual existente em seu tempo. O método de investiga o histórica presente em seus artigos veiculados pela revista Annales foi reformulado por seus sucessores, com o passar das décadas e os novos problemas sociais surgidos, mas a obra de Febvre continua sendo referência para os historiadores atuais contendo ainda muito a ser desvelado, conforme proposto por André Burguière. Dessa forma, no presente artigo nos propomos analisar a heran a quádrupla no desenvolvimento de seu método de investiga o e proposta teórica para o campo de estudo da biografia.
A história estrutural: trajetória, conceitos e aplicabilidade

BIBLOS : Revista do Instituto de Ciências Humanas e da Informa??o , 2010,
Abstract: Na Fran a, o movimento posteriormente intitulado de Annalistes exerceu uma verdadeira hegemonia no processo de renova o dos métodos e problemáticas da História. Entretanto, suas reflex es permaneceram muito mais no campo da epistemologia do que propriamente da teoria histórica. Somente as gera es posteriores a Marc Bloch e Lucien Febvre, chamados os pais fundadores dos Annales, buscaram a sistematiza o de metodologias e esbo os de uma possível teoria, inspirada por diversas ciências – lingüística, geografia, psicologia, antropologia, sociologia, entre outras. A partir dessa percep o, propomos no presente artigo, debru ados sobre o texto-manifesto de Fernando Braudel “História e Ciências Sociais”, a discuss o do desenvolvimento das análises de cunho estrutural na história, n o apenas enquanto teoria, mas principalmente enquanto método, de forma que possamos perceber as possibilidades de aplica o da abordagem estrutural na pesquisa histórica.
