Prevalência, classifica??o e características do refluxo cecoileal diagnosticado pelo enema opaco
Machado, Wellington Monteiro;Morceli, José;
Radiologia Brasileira , 2006, DOI: 10.1590/S0100-39842006000200007
Abstract: objective: retrospectively determining the coloileal reflux prevalence at the barium enema examination, characterizing its distribution by sex and age range and classifying it according to the intensity degree. materials and methods: 715 barium enemas were reviewed, being 268 of male patients and 447 of female patients, with average age of 54 years. results: of the 715 enemas performed, 46.5% showed coloileal reflux, classified as mild (45%), moderate (37.5%) and severe (17.5%). coloileal reflux was present in 48.3% of female and in 43.6% of male patients. the coloileal reflux distribution by age range was 46.1% in individuals less than 21 years, 42.1% in individuals between 21-40, 49.8% in individuals between 41-60 and 44.7% in people more than 60 years old. conclusion: coloileal reflux was a common finding, with 25% of them being classified as moderate or severe. apparently, there is not a clear relationship between its occurrence and gender or age. the etiopathogenesis and consequences of the coloileal reflux remain still poorly known. some studies suggest that the compromising of ileocecal junction components, like ligaments, could favor the coloileal reflux occurrence. among the probable consequences, we could mention contamination and ileal motility disorders resulting from the material refluxed from cecum into the ileum.

Abstract: we evaluated the adrenals of individuals without tuberculosis (group 1 - g1) and with tuberculosis (group 2 - g2) using computed tomography. the antero-posterior length, the thickness, and the longitudinal length of the adrenals were compared in g1 and g2. the duration of the disease, the occurrence of morphologic abnormalities in g2, the distribution according to sex, age and skin color were also studied. there was difference in the antero-posterior length and thickness of right adrenal between g1 and g2. a higher prevalence of white skin male individuals was observed in g2. there was no association between duration of the disease and the occurrence of morphologic abnormalities in g2. a higher occurrence of adrenal enlargement was observed in g2. the main computed tomography findings in patients with tuberculosis were enlargement of the adrenal without calcification, enlargement of the adrenal with punctiform calcifications, and residual calcification of the adrenal.

Abstract: Neste estudo foram avaliadas, por meio de tomografia computadorizada, as adrenais em indivíduos sem tuberculose (grupo 1 - G1) e com tuberculose (grupo 2 - G2). A dimens o antero-posterior, a espessura e o comprimento das adrenais foram comparados no G1 e no G2. Foram também avaliadas a dura o da doen a com a ocorrência de altera o morfológica no G2, e a distribui o segundo o sexo, a idade e a cor da pele no G1 e no G2. Neste estudo houve diferen a nas dimens es antero-posterior e espessura da adrenal direita entre o G1 e o G2. Observou-se maior ocorrência do sexo masculino e de indivíduos de pele branca no G2. N o houve associa o entre a dura o da doen a e a ocorrência de altera o morfológica no G2. Maior ocorrência da altera o morfológica tipo alargamento foi observada no G2. Os principais achados pela tomografia computadorizada, nos pacientes com tuberculose, foram alargamento da adrenal sem calcifica o, alargamento da adrenal com calcifica o puntiforme e calcifica o de aspecto residual da adrenal.
The small bowel flora in individuals with cecoileal reflux
Machado, Wellington Monteiro;Miranda, José Ricardo Arruda;Morceli, José;Padovani, Carlos Roberto;
Arquivos de Gastroenterologia , 2008, DOI: 10.1590/S0004-28032008000300009
Abstract: background: the observation of cecoileal reflux to barium enema is not rare; however, its causes and consequences have not been widely investigated. considering that ileocecal junction exerts a function as barrier to invasion of bacteria from colon to small bowel, it seems interesting to study the intestinal microflora in subjects carrying cecoileal reflux. aims: this study aims at evaluating the ileal flora in individuals with cecoileal reflux. methods: a group of 36 subjects comprising 30 females and 6 males with a mean age of 54 years was assessed. twenty-five individuals with cecoileal reflux and 11 without cecoileal reflux were submitted to small intestine contamination evaluation through the breath test with lactulose-h2 and measurement of the orocecal transit time by means of alternate current biosusceptometry. small intestine bacterial overgrowth was characterized by orocecal transit time-h2 shortening. results: comparison of basal h2, orocecal transit time-h2 and orocecal transit time-alternate current biosusceptometry measurements did not statistically differ between the groups with and without cecoileal reflux. orocecal transit time-h2 was significantly smaller than orocecal transit time-alternate current biosusceptometry, particularly in individuals with cecoileal reflux. a significant correlation between the two methods was observed only in relation to control, not existing in relation to cecoileal reflux group. conclusions: smaller orocecal transit time-h2 and the loss of correlation with orocecal transit time-alternate current biosusceptometry observed in the individuals with cecoileal reflux suggest a differentiated behavior for such group relative to control, which could be associated with small intestine bacterial overgrowth.

Abstract: this paper presents a different roof tiles influence study on the thermal comfort for broiler housings. the research was conducted at unesp's experimental campus at dracena, state of s?o paulo, brazil. four prototypes in real scale were built, each with an area of 28 m2. the prototype was covered with roof tiles made of recycled long-life packing material, ceramic tiles, ceramic tiles painted with white coating, and fiber/cement tiles. temperatures inside the structures were recorded in the winter 2007 over a 90-day period. the results obtained indicated that recycled tile thermal behavior was similar to ceramic tiles. however for the winter period all the prototypes had presented comfort thermal index not in the broilers thermo neutral zone.

Abstract: objective: the aim of this study is the optimization of mammographic images with a considerable radiation dose reduction. materials and methods: in the present study the x-ray beam was calibrated for each tension (kvp), aiming at determining the best combination between kvp and mas, resulting in optical densities of about 1.0 above the base-plus-fog density. results: this study will bring into question the methods for x-ray beam calibration, the choice of the best image by means of visual grading analysis, comparisons between doses and tube load (kvp × mas) delivered by the techniques described in this study and by those adopted in the clinical routine at service of diagnostic imaging of faculdade de medicina de botucatu clinics hospital, botucatu, sp, brazil. excellent breast radiographic images have been obtained with doses and tube loads reduction of respectively 36.8% and 46.2% in comparison to those employed in our institutions' clinical routine. conclusion: this study is a contribution to the optimization of the risk-benefit ratio for patients and cost-benefit ratio for the institution.

Abstract: this paper presents a study of the influence of roof tiles made of recycled long-life packaging (brand-name ibaplac?) on the thermal comfort of zootechnical facilities. the research was conducted at unesp's experimental campus at dracena, state of s?o paulo, brazil. four prototypes were built, each with an area of 28 m2. one prototype was covered with roof tiles made of recycled long-life packing material and three reference prototypes were roofed with ceramic tiles, ceramic tiles painted white and fiber/cement tiles (brasilit?), respectively. black globe thermometers and dry and wet bulb thermometers were installed inside the prototypes. temperatures inside the structures were recorded in the summer of 2006/2007 over a 90-day period. a descriptive statistical analysis was made, based on the mean values of black globe temperature and humidity index, radiant thermal load and temperature-humidity index of the period. the results obtained indicated that the thermal behavior of the recycled tile was similar to that of the ceramic tiles.
