Câncer de pele: uso de medidas preventivas e perfil demográfico de um grupo de risco na cidade de Botucatu

Buscou-se junto a um grupo de risco para o câncer de pele seu o perfil demográfico e analisou-se o uso de medidas preventivas utilizadas pelos mesmos e pela empresa. Estudo quantitativo com 33 carteiros da Empresa Brasileira de Correios e Telégrafos em Botucatu, Brasil. Dados obtidos por meio de um formulário que investigava perfil demográfico, tempo de trabalho na empresa, horário de exposição ao sol, história de queimaduras solares, história de câncer na família e formas de prevenção do câncer de pele utilizadas. Na análise dos dados, utilizou-se estatística descritiva segundo Teste Exato de Fisher ao nível de 5% de probabilidade. Os resultados mostraram que a faixa etária predominante foi de 26 a 30 e de 31 a 35 anos, correspondendo a 42,42% da amostra, a cor da pele foi à branca com 93,94% e 81,82% trabalham há mais de cinco anos na empresa. O hábito de usar filtro solar foi encontrado em 63,63% dos entrevistados, sendo a não aderência a este justificada em 75% por falta de costume. em relação aos equipamentos protetores do sol a empresa fornece para 100% deles. Os achados permitem a caracterização da população estudada, identificada como de risco para o câncer de pele, propiciando a profilaxia através de ações em saúde, visando à sensibilização dos mesmos para com as medidas preventivas que podem ser adotadas.

Distinção entre areias eolicas e praiais pele analise discriminante

Beach deposits occur in high energy environments with continual sorting by swash and backswash. The fines are removed by the backswash, which is not competent to remove the coarser material. Hence negative asymmetry (skewness) results. The wind transports only the finer fraction to the dunes, resulting in a tendency towards a positively skewed distribution. In the case studied the aeolian sand has a mean asymmetry of 0.13, the beach sand -0.11. Equivalent values for mean grain size and standard deviation are 2.51 and 0.24 (aeolian) and 2.41 and 0.37 (beach). Beach sands are therefore coarser and less well sorted than aeolian sands. -V.Gardiner

Tratamento de ulcera varicosa e lesoes de pele com Calendula officinalis L. e/ou com Stryphnodendron barbadetiman (Vellozo) Martius

Calendula officinalis L. and S. barbadetiman are used in Brazil for the treatment of a number of aliments. The healing properties of these substances are well known, mainly in domestic or sun burn. In order to establish a pharmacological rationale for the traditional use of these plants as a cicatrizant or antiinflammatory remedy, we used ethanol extracts or gel from stem bark of the S. barbadetiman and inflorescence of the Calendula. We selected four groups of patients; two groups shown varicose ulcer (I, II) and two groups shown skin lesions (III and IV). Groups I and III were treated with Calendula and group II and IV were treated with Calendula plus barbadetiman. The data in this study suggest that the treatment with Calendula or Calendula plus barbadetiman are effective in the process that brings wounds to a close. These findings provide basis to an alternative treatment of varicose ulcer.

Importância de Yersinia enterocolitica em microbiologia médica

Y. enterocolitica is a human invasive enteropathogen which causes a number of intestinal and extraintestinal clinical symptoms of various degrees of severity, ranging from mild gastroenteritis to mesenteric lymphadenitis, which mimics appendicitis and in rare cases can evolve to septicemia. Infection by Y. enterocolitica can also lead to post-infection immunological sequelae including arthritis, erythema nodosum and glomerulonephritis. Pathogenic Y. enterocolitica strains have traditionally been linked to specific biotypes and serogroups and associated to a variety of phenotypic characteristics related to virulence. Molecular genetics studies have pointed to the importance of the pYV virulence plasmid, which encodes various virulence genes, as well that of specific chromosomal virulence genes, in determining the pathogenesis of this bacterium. Intestinal infections by Y. enterocolitica are mostly self-limiting and usually do not need an antibiotic treatment. The occurrence of this microorganism is not as frequently described in Brazil as it is in other countries, such as Japan, USA and many European countries. This review focuses on the general characteristics, pathogenesis, clinical symptoms, virulence characteristics, treatment and antibiotic susceptibility of Yersinia enterocolitica strains isolated in Brazil and around the world.

Avaliação histológica da pele após exposição a gel acrescido de hialuronidase associado ou não a ultra-som

The objective of this work was to verify the effect in the skin of male swines gel (G) containing hyaluronidase (H) associated or not to ultrasound (US). In different areas was applied G; G+US; G+H; G+H+US and mesotherapy (M). Skin fragment was processed in paraffin. To evidence hyaluronic acid (HA) coloration with Alcian Blue (AB) was used and coloration with Hematoxilin/Eosin for morphometry. It was observed that G+H and G+H+US did not reduce coloration for the AB nor presented significant differences for the morphometry. When H was applied mesoteraphycally coloration for the AB diminished. Then, the use of H associated or with US did not seem efficient in the HA reduction.

Crescimento e acúmulo de nitrogênio e potássio pelo melão pele de sapo fertirrigado

With the objective of obtaining dry matter curves, and nitrogen and potassium accumulation in Piel de Sapo melon (Cucumis melo L.) hybrid Sancho, an experiment was conducted in Mossoró - RN in a randomized blocks design with three repetitions. Treatments consisted of doses in kg ha-1 of nitrogen: 0, 91, 140 and 184 and potassium: 0, 174, 260 and 346; which were applied by fertigation in depths of 281, 349 and 423mm. Stems, leaves and fruits were harvested 5 times at 28 to 70 days after transplantation, in intervals of 10 days for analyses of aerial dry matter, nitrogen, and potassium accumulation. Doses higher than 140 and 260 kg ha-1 of N and K respectively, did not induce greater accumulation of these nutrients increasing levels throughout the plant cycle. Nitrogen doses of 91 and 140 kg ha-1, potassium doses of 174 and 260 kg ha-1 as well as depth of 348mm provided higher accumulation of potassium in the plant.

Efeitos do extrato de parede de levedura em dieta seca sobre a Microbiologia, ácidos graxos de cadeia curta e redução do odor das fezes de gatos adultos

The aim of this study was to evaluate the effects of yeast cell wall extract (YCW) in dry diet on the fecal microbiota, concentration of short-chain fatty acids (SCFA) and on the odor reduction of cats feces. We used 20 animals of both sexes, randomly assigned to four treatments and five repetitions totaling 20 experimental units: 1) dry commercial diet (control); 2) control + 0.2%, 3) control + 0.4%, and 4) control + 0.6% of YCW in dry matter. Enterobacteriaceae and lactic acid bacteria, fecal concentration of acetic, propionic and butyric acids, ammonia nitrogen and sensory panel were performed. There were no significant differences (p> 0.05) for bacterial counts and the concentration of SCFA and ammonia, but in sensory panel a reduction in the odor of feces could be noted with the use of 0.2% of YCW. We concluded that the addition of up to 0.6% YCW had no effect on the microbiology and the concentration of fatty acids, but there is potential for its use as an additive because of the improvement in the odor of feces. However, further studies are needed to understand the mechanisms of action and the effects of prebiotics for domestic cats.
