Tinha Incognita

Contexto:A tinha incógnita é infecção fúngica cutânea causada por dermatófito e agravada por tratamento incorreto. Os principais medica-mentos envolvidos são os corticosteroides tópicos, sistêmicos e aplicação tópica de imunomodulador. Nessa enfermidade, as lesões perdemo formato anular ou circinado típico com atividade clínica periférica, manifestando-se clinicamente como máculaseritemato-descamativascom pústulas ou placas e nódulos eritematosos infiltrados, mimetizando diversas doenças cutâneas.Descrição do caso:Relatamos o casode paciente feminina, de sete anos de idade, caucasiana, com lesões eritemato-descamativas pustulosas e história clínica dedois meses.Foi tratada previamente com antibióticos (cefalexina via oral), corticosteroides tópico e injetável, com piora progressiva do quadro. Estabe-leceu-se o diagnóstico de tinha incógnita pelo exame clínico e micológico direto. Houve cura das lesões após tratamento com terbinafina viaoral, 125 mg/dia, e antimicótico tópico por oito semanas.Conclusões:A tinha incógnita, pela apresentação clínica atípica, requer atenção.Assim, o médico deve conhecê-la e pesquisar os fungos dermatófitos em lesões cutâneas faciais com distribuição atípica, recalcitrantes elocalizadas muitas vezes no couro cabeludo.Palavras-chave:Tinha do couro cabeludo, tinha, micoses, fungos, corticosteroides

Orquiepididimite causada por Corynebacterium sp e Proteus mirabilis em cordeiro da raça Lacaune: relato de caso

Orchiepididymitis is the inflammation of both, testis and epididymis and may be caused by microbial agents such as Brucella ovis. Thus, the aim of the present report is to present a case of orchiepididymitis in a Lacaune ram with unilateral testicular enlargement. Ultrasonography of the testis revealed the presence of a circular hypoechogenic structure adjacent to the testicular parenchyma. Corynebacterium sp was isolated from the surgically removed testis. Two months after removal of the affected testis, the animal returned to the Veterinary Hospital due to an enlargement of the remaining testis. A new ultrasonographic exam revealed the presence of abscesses in the testicular parenchyma and periorchitis. After orchiectomy, Proteus mirabilis was isolated from the material.

Efeitos do treinamento aeróbio e de força sobre a área de secção transversal (AST) das fibras do músculo plantar de ratos

Recent research seeking to elucidate the possible effects of different types of physical training on the morphological adaptations of skeletal muscle. Although it is relatively easy to study the effects of exercise training in humans, such research becomes limited due to the invasive nature of the biopsies and the risk inherent in the use of human subjects. Thus, the application of animal models of training has been considered an appropriate strategy for the study of muscular adaptations in response to exercise. Objective: This study used a rodent model to determine the possible effects of aerobic and strength training on the CSA of fibers of the plantaris muscle. Methods: 24 male Wistar rats (80 to 120 days, 250 to 400 g) were randomly divided into 3 groups: aerobic training (TA, n = 8), strength training (ST, n = 8) and control (CO, n = 8). The animals in groups TA and TF were subjected to 8 weeks of training, while the animals of group C remained without any stimulus from start to finish the training period. At the end of the experiment, the animals were sacrificed and right plantar muscles dissected and removed. For morphological and morphometric analysis of muscle fibers was performed staining was performed H.E. Results: There was no significant difference in initial body weight between experimental groups. After 8 weeks of training, the TA group showed a significant reduction in final body weight, compared to CO and TF groups. With respect to the CSA of fibers of the plantaris muscle, no significant difference between the groups CO and TA. On the other hand, the strength training promoted a significant increase in AST of the group TF in compared with the groups CO and TA. Conclusion: Strength training used in this study promoted an increase in CSA of fibers of the plantaris muscle. On the other hand, animals submitted to aerobic training showed no changes in the CSA of the fibers, however, there was reduction in PC animals. The data strongly suggest the use of animal model of strength training used in this study as an appropriate strategy for studying the hypertrophic response of skeletal muscle.

Avaliação in vitro do crescimento micelial de cinco linhagens de Agaricus blazei em duas temperaturas

The objective of the work was to evaluate the in vitro mycelial growth of five A. blazei strains (ABL-05/53, ABL-04/49, ABL-03/44, ABL-99/30 and ABL-02/51) when submitted to the temperatures of 20 and 25 ºC. In a laminar flow chamber, discs of the strains were inoculated in the middle of Petri’s plates containing CA (compost-agar) medium and incubated in BOD. After 48 hours, measurements of the mycelial growth began, with the help of a ruler with scale in millimeters, by means of four equidistant measurements, until the moment when the fungal colony reached near the edges of the Petri’s plate in one of the treatments. The experimental design was totally randomized, in 5 x 2 factorial design. Each treatment consisted of seven repetitions, corresponding to one Petri’s plate, totalizing seventy experimental units. We verified that A. blazei growth is influenced by incubation temperature, being that the temperature of 25 ºC was more favorable for the mycelial growth of all A. blazei strains tested, with attention for ABL-04/49 and ABL-03/44 strains, which obtained the highest averages for mycelial growth under this temperature condition at the end of the cultivation cycle.

Produção semissólida de metarhizium anisopliae e beauveria bassiana em diferentes substratos e efeito da radiação ultravioleta e da temperatura sobre propágulos desses entomopatógenos

The present study was aimed to evaluate different (semi-solid) media for the production of Metarhizium anisopliae and Beauveria bassiana propagules, and to evaluate the tolerance of these propagules to ultraviolet radiation and temperature. The experiments were performed at the Biological Control Laboratory of the Instituto Biológico at Campinas, São Paulo, Brazil. For both fungi, 6 repetitions were performed for each of the 17 treatments: corn starch, full rice, parboiled rice, type-1 rice, type-2 rice, oat flakes, canjiquinha [grits], wheat flour, raw cassava flour, yellow corn flour, special wheat flour, corn flour, corn in grains, cassava starch, soy in grains, crushed wheat, and turf. The viability analysis was done in plastic plates containing BDA. For the bioassays involving exposure to ultraviolet light and temperature, BDA was also used for viability analysis, and each treatment was exposed to the UV radiation for 0, 25 and 50 seconds, the temperature exposure being at 20, 25, 30 and 35º C. Using a Potter tower, 2 mL of fungus suspension from each treatment was inoculated to the Diatraea saccharalis caterpillars. Regarding the sporulation, the largest concentrations of M. anisopliae and B. bassiana were found for the treatments with parboiled rice, type-1 rice, type-2 rice, yellow corn flour, corn flour and crushed wheat. The viability of all treatments was superior to 94.00%. Also, the longer the duration of the exposition to the UV, the smaller the number of fertile conidia. At 35o C, a significant loss of conidia viability was observed, and all the treatments presented some level of virulence.
