Produção Fecal e Fluxo Duodenal de Matéria Seca e Matéria Orgânica Estimados por Meio de Indicadores

O objetivo deste trabalho foi comparar os indicadores internos, fibra em detergente neutro e fibra em detergente ácido indigestíveis, obtidos após 144h de incubação in vitro e in situ (FDNiv; FDNis; FDAiv; FDAis) com o indicador externo, o óxido crômico (Cr2O3), para estimativas da produção fecal, do fluxo duodenal de matéria seca e matéria orgânica em novilhos mestiços (HxZ) confinados. Foram utilizadas dietas à base de silagens de milho, de raspa e de casca de mandioca, e também de cana-de-açúcar ensilada com polpa cítrica peletizada. Os novilhos foram castrados e canulados no rúmen e no duodeno. O período experimental teve 11 dias de adaptação às dietas e 8 dias de coleta. O delineamento experimental foi o quadrado latino (4x4), com quatro tratamentos, num arranjo em parcela subdividida, sendo as dietas estudadas nas parcelas, e os indicadores nas subparcelas. Os resultados obtidos em percentagem do peso vivo para a estimativa da produção fecal, utilizando-se os diferentes indicadores, mostraram que a FDAiv (0,88 %), a FDAis (0,85 %) e o Cr2O3 (0,99 %), embora com diferenças significativas, podem ser utilizados pelos resultados biologicamente consistentes. Para estimar o fluxo duodenal de matéria seca e matéria orgânica, foram utilizados os valores de produção fecal obtidos com a FDAiv. Os indicadores internos não apresentaram diferenças entre si para o fluxo duodenal de matéria seca, com média de 3,29 kg/dia, porém o óxido crômico superestimou o fluxo (4,95 kg/dia). Para o fluxo duodenal de matéria orgânica não houve diferença entre os indicadores com média de 2,73 kg/dia.

Comparação de marcadores para estimativas de produção fecal e de fluxo de digesta em bovinos

Foram realizados três experimentos procurando avaliar a utilização de dois marcadores internos (FDN e FDA indigestíveis), obtidos por meio da incubação in vitro e in situ, e de um marcador externo (óxido crômico) para estimativa da produção fecal e do fluxo da digesta duodenal em bovinos. Para análise dos dados, adotou-se o delineamento em blocos inteiramente ao acaso, sendo os tratamentos distribuídos em esquema fatorial, constituindo cinco marcadores e três volumosos. Os teores de FDN e FDA indigestíveis mostraram-se variáveis para cada volumosos, independentemente da metodologia utilizada (in vitro ou in situ), indicando que possivelmente a incubação por 144 horas não reproduz a fração indigestível total. As estimativas de produção fecal e de fluxo da digesta duodenal, obtidas por intermédio dos marcadores avaliados, apresentaram comportamento bastante diferenciado de acordo com cada volumoso. Os marcadores internos (FDN e FDA indigestíveis) podem ser utilizados como preditores dos parâmetros avaliados, desde que alguns cuidados sejam tomados na sua determinação.

Intravaginal electrical stimulation: a randomized, double-blind study on the treatment of mixed urinary incontinence

Background the aim of this study was to compare effective and sham intravaginal electrical stimulation (IES) in treating mixed urinary incontinence. Methods. Between January 2001 and February 2002, 40 women were randomly distributed, in a double-blind study, into two groups: group G1 (n = 20), effective IES, and group G2 (n = 20), sham IES, with follow up at one month. Different parameters was studied: 1. clinical questionnaire, 2. body mass index; 3. 60-min pad test; 4. urodynamic study. The protocol of IES consisted of three 20-min sessions per week over a seven-week period. The Dualpex Uro 996 used a frequency of 4 Hz. Results. There was no statistically significant difference in the demographic data of both groups. The number of micturitions per 24 h after treatment was reduced significantly in both groups. Urge incontinence was reduced to 15% in G1 and 31.5% in G2; there was no significant difference between the groups. In the analog wetness and discomfort sensation evaluations were reduced significantly in both groups. The pretreatment urodynamic study showed no statistical difference in urodynamic parameters between the groups. Ten percent of the women presented involuntary detrusor contractions. In the 60-min pad test, there was a significant reduction in both groups. In regards to satisfaction level, after treatment, 80% of G1 patients and 65% of G2 patients were satisfied. There was no statistically significant difference between the groups. Conclusion. Significant improvement was provided by effective and sham electrostimulation, questioning the effectiveness of electrostimulation as a monotherapy.

A comparative analisys of pelvic floor muscle strength in women with stress and urge urinary incontinence

Aims: To assess pelvic floor muscle (PFM) strength in women with stress urinary incontinence (SUI) and urge urinary incontinence (UUI).Materials and Methods: 51 women were prospectively divided into two groups, according to the symptoms as SUI (G1 = 22) or UUI (G2 = 29). Demographic data, such as number of pads/ 24 hours, number of micturations/ 24 hours and nocturia, delay time of urgent void (i.e., the time period for which an urgent void could be voluntarily postponed), number of parity and vaginal deliveries were obtained using a clinical questionnaire. Objective urine loss was evaluated by 60-min. Pad Test, subjective urine stream interruption test (UST) and visual survey of perineal contraction. Objective evaluations of PFM were performed in all patients (vaginal manometry).Results: Median of age, mean number of pads/ 24 hours, nocturia and warning time were significantly higher in UUI comparing to SUI group. During UST, 45.45% in G1 and 3.44%, in G2, were able to interrupt the urine stream (p < 0.001). The 60-min. Pad Test was significantly higher in G2 compared to G1 women (2.7 +/- 2.4 vs 1.5 +/- 1.9 respectively, p = 0.049). Objective evaluation of PFM strength was significantly higher in the SUI than in the UUI patients. No statistical difference was observed regarding other studied parameters.Conclusion: Pelvic floor muscle weakness was significantly higher in women with UUI when compared to SUI.

Vaginal weight cone versus assisted pelvic floor muscle training in the treatment of female urinary incontinence. A prospective, single-blind, randomized trial

Vaginal weight cone (VWC) versus assisted pelvic floor muscle training (APFMT) in the treatment of urinary incontinence (UI) in women.One hundred three incontinent women were randomly distributed into two groups: group G1 (n = 51) treated with VWC and G2 (n = 52), APFMT. The following parameters were performed initially and after treatment: (1) clinical questionnaire, (2) visual analogue scale (VAS), (3) 60-min pad test, and (4) subjective and objective assessment of pelvic floor muscle (PFM).There was a significant decrease in nocturia and urine loss after treatment in both groups (p < 0.05). In VAS, there was a significant improvement of all parameters in both groups (p < 0.05). The pad test showed significant decrease in both groups (p < 0.05). There was a significant increase of PFM strength in both groups (p < 0.05).There was no difference between groups treated with VWC and APFMT.

Taenia saginata: polymerase chain reaction for taeniasis diagnosis in human fecal samples

The taeniasis-cysticercosis complex is a zoonosis of great medical and economic importance where humans play an important role as the carrier of adult stage of Taenia solium and Taenia saginata. This paper describes PCR standardization that can be applied in human fecal samples for taeniasis diagnosis. DNA extraction was achieved with DNAzol reagent, after egg disruption with glass beads. DNA prepared from fecal specimens was first purified and PCR amplified generating fragments of 170 and 600 bp. The assay described herein provides an important tool for T saginata identification in human fecal samples. (C) 2003 Elsevier B.V. (USA). All rights reserved.

Molecular identification of Cryptosporidium spp. from fecal samples of felines, canines and bovines in the state of São Paulo, Brazil

The objective of this study was to obtain information of epidemiological nature through genotypic characterization of Cryptosporidium isolates from dogs, cats and bovines from the state of São Paulo, Brazil. The extraction of DNA from oocysts was carried out and polymerase chain reaction was accomplished using specific primers to 18S rRNA gene. The amplicons were directed sequenced. Seven cat samples, nine dog samples and nine bovine samples were analysed. From the seven cat samples the genotypic analyses revealed Cryptosporidium felis in all. These were the first genotypic characterization of Cryptosporidium from domestic felines in Brazil. In nine sequenced samples from dogs, genotypic identities compatible with Cryptosporidium canis were revealed in all samples. The genotypic analyses in bovines revealed Cryptosporidium parvum in eight samples and Cryptosporidium bovis in another sample, the last one being a non-zoonotic species, not related to clinical symptoms and described for the first time in Brazil.
