RESUMO

PURPOSE: Chronic pelvic pain (CPP) in women is a complex syndrome and symptoms are associated with sexual dysfunction, musculoskeletal and myofascial disorders, and comorbid psychiatric disorders. Its widespread prevalence results in substantial expense due to therapy and lost productivity, and it is perhaps one of the most urgent and neglected medical needs. This systematic review and meta-analysis aimed to estimate the role of mindfulness and pelvic floor physical therapy (PFPT) in the treatment or management of women with CPP. METHODS: This systematic review (CRD42020204987) searched for relevant publications between January 2000 and November 2020 on MEDLINE/PubMed, Web of Science, One File GALE, and Technology Research databases using the following search terms: chronic pelvic pain, pelvic floor physical therapy/physiotherapy, mindfulness, and their variants. Risk of bias and quality of evidence were evaluated. RESULTS: Seven clinical trials (n = 279) were included in the review, and five in the meta-analysis (n = 225). For the pain outcome and its catastrophizing, there was a statistical difference for the Pain Catastrophizing Scale after treatment and during follow-up with mindfulness and PFPT (MD = - 3.82 [- 6.97, - 0.68], p = 0.01, and MD = - 4.49 [- 7.61, - 1.37], p = 0.00, respectively). Sexual function, assessed by the female sexual function index, differed significantly during follow-up between PFPT and mindfulness (MD = - 0.72 [- 1.38, - 0.05], p = 0.03). CONCLUSION: The small number of studies applying both PFPT and mindfulness to CPP suggests that a multidisciplinary approach is required to treat women with CPP, and further studies involving these therapeutic techniques throughout the CPP cycle are needed.

RESUMO

Extraintestinal pathogenic Escherichia coli (ExPEC) is the leading cause of urinary tract infection worldwide and a critical bloodstream infection agent. There are more than 50 virulence factors (VFs) related to ExPEC pathogenesis; however, many strains isolated from extraintestinal infections are devoid of these factors. Since opportunistic infections may occur in immunocompromised patients, E. coli strains that lack recognized VFs are considered opportunist, and their virulence potential is neglected. We assessed eleven E. coli strains isolated from bloodstream infections and devoid of the most common ExPEC VFs to understand their pathogenic potential. The strains were evaluated according to their capacity to interact in vitro with human eukaryotic cell lineages (Caco-2, T24, HEK293T, and A549 cells), produce type 1 fimbriae and biofilm in diverse media, resist to human sera, and be lethal to Galleria mellonella. One strain displaying all phenotypic traits was sequenced and evaluated. Ten strains adhered to Caco-2 (colon), eight to T24 (bladder), five to HEK-293 T (kidney), and four to A549 (lung) cells. Eight strains produced type 1 fimbriae, ten adhered to abiotic surfaces, nine were serum resistant, and seven were virulent in the G. mellonella model. Six of the eleven E. coli strains displayed traits compatible with pathogens, five of which were isolated from an immune-competent host. The genome of the EC175 strain, isolated from a patient with urosepsis, reveals that the strain belonged to ST504-A, and serotype O11:H11; harbors thirteen VFs genes, including genes encoding UpaG and yersiniabactin as the only ExPEC VFs identified. Together, our results suggest that the ExPEC pathotype includes pathogens from phylogroups A and B1, which harbor VFs that remain to be uncovered.

RESUMO

Magnetic resonance imaging (MRI) has been increasingly used in the detection, localization, and staging of prostate cancer. Because of its excellent soft tissue contrast and multiplane imaging, it can be also very useful in the evaluation of benign prostate diseases. Prostatic benign disorders have a high prevalence, vastly represented by benign prostatic hyperplasia and prostatitis. On the contrary, benign prostatic neoplasms are extremely rare, represented by multilocular cystadenoma, leiomyomas, hemangioma, and granular cell tumor, although these uncommon tumors have been most encountered due to widespread use of MRI. Congenital prostatic anomalies are associated with defects in the development of the prostate embryology, including hypoplasia, ectopia, and vascular malformations, abnormalities rarely seen on cross-sectional imaging. Prostatic cysts are the most common development abnormalities and occasionally are related to clinical symptoms, mainly due to infection and hemorrhage. As with prostate cancer, multiparametric MRI is a reliable tool for the diagnosis and management of benign prostatic diseases as well, providing additional information such morphological changes of the prostate, more accurate prostatic measurements, and functional characteristics of nonmalignant prostatic lesions. In this review, we discuss MRI findings of these benign prostatic diseases.

RESUMO

OBJECTIVE: To assess the reduction of estimated radiation dose in abdominal computed tomography following the implementation of new scan protocols on the basis of clinical suspicion and of adjusted images acquisition parameters. MATERIALS AND METHODS: Retrospective and prospective review of reports on radiation dose from abdominal CT scans performed three months before (group A - 551 studies) and three months after (group B - 788 studies) implementation of new scan protocols proposed as a function of clinical indications. Also, the images acquisition parameters were adjusted to reduce the radiation dose at each scan phase. The groups were compared for mean number of acquisition phases, mean CTDIvol per phase, mean DLP per phase, and mean DLP per scan. RESULTS: A significant reduction was observed for group B as regards all the analyzed aspects, as follows: 33.9%, 25.0%, 27.0% and 52.5%, respectively for number of acquisition phases, CTDIvol per phase, DLP per phase and DLP per scan (p < 0.001). CONCLUSION: The rational use of abdominal computed tomography scan phases based on the clinical suspicion in conjunction with the adjusted images acquisition parameters allows for a 50% reduction in the radiation dose from abdominal computed tomography scans.


OBJETIVO: Quantificar a redução da dose estimada de radiação em exames de tomografia computadorizada de abdome após a implementação de novos protocolos dirigidos para a suspeita clínica e ajuste nos parâmetros técnicos de aquisição. MATERIAIS E MÉTODOS: Foram avaliados, de forma retrospectiva e prospectiva, os relatórios de dose de exames de tomografia computadorizada de abdome realizados três meses antes (grupo A ­ 511 exames) e três meses após (grupo B ­ 788 exames) a implementação de novos protocolos de exame propostos em função das indicações clínicas. Contemporaneamente, os parâmetros de aquisição das imagens foram ajustados de modo a reduzir a exposição em cada fase do exame. Os grupos foram comparados quanto ao número médio de fases de aquisição, valores de CTDIvol por fase, DLP por fase e DLP por exame. RESULTADOS: O grupo B apresentou redução significativa em todos os aspectos analisados: número de fases, CTDIvol por fase, DLP por fase e DLP por exame mostraram reduções de 33,9%, 25,0%, 27,0% e 52,5%, respectivamente (p < 0,001). CONCLUSÃO: O uso racional das fases de aquisição dirigidas para a suspeita clínica, em conjunto com adequação nos aspectos técnicos, permite reduzir pela metade a dose de radiação por exame de tomografia computadorizada de abdome.

RESUMO

Objective To evaluate the diagnostic capacity of abdominal computed tomography in the assessment of hepatic steatosis using the portal phase with a simplified calculation method as compared with the non-contrast-enhanced phase. Materials and Methods In the present study, 150 patients were retrospectively evaluated by means of non-contrast-enhanced and contrast-enhanced computed tomography. One hundred patients had hepatic steatosis and 50 were control subjects. For the diagnosis of hepatic steatosis in the portal phase, the authors considered a result of < 104 HU calculated by the formula [L - 0.3 × (0.75 × P + 0.25 × A)] / 0.7, where L, P and A represent the attenuation of the liver, of the main portal vein and abdominal aorta, respectively. Sensitivity, specificity, positive and negative predictive values were calculated, using non-contrast-enhanced computed tomography as the reference standard. Results The simplified calculation method with portal phase for the diagnosis of hepatic steatosis showed 100% sensitivity, 36% specificity, negative predictive value of 100% and positive predictive value of 75.8%. The rate of false positive results was 64%. False negative results were not observed. Conclusion The portal phase presents an excellent sensitivity in the diagnosis of hepatic steatosis, as compared with the non-contrast-enhanced phase of abdominal computed tomography. However, the method has low specificity. .


Objetivo Comparar a capacidade diagnóstica para esteatose hepática utilizando-se a fase portal com método simplificado de cálculo com a fase sem contraste na tomografia computadorizada de abdome. Materiais e Métodos Foi realizado estudo retrospectivo em 150 pacientes submetidos a tomografia computadorizada de abdome sem e com contraste intravenoso, 100 deles com esteatose hepática e 50 controles. Para diagnóstico de esteatose hepática na fase portal considerou-se um resultado < 104 UH aplicando-se a fórmula [L - 0,3 × (0,75 × P + 0,25 × A)] / 0,7, onde L, P e A representam a atenuação hepática, da veia porta e da aorta, respectivamente. Foram calculados sensibilidade, especificidade, valores preditivos positivos e negativos, utilizando-se a tomografia computadorizada sem contraste intravenoso como padrão de referência. Resultados O método simplificado de cálculo para o diagnóstico de esteatose hepática na fase portal mostrou sensibilidade de 100%, especificidade de 36%, valor preditivo negativo de 100% e valor preditivo positivo de 75,8%. A taxa de falso-positivos foi 64%. Não foram encontrados falso-negativos. Conclusão A utilização da fase portal apresenta elevada sensibilidade para o diagnóstico de esteatose hepática, quando comparada à fase sem contraste da tomografia computadorizada de abdome. Por outro lado, o método apresenta baixa especificidade. .

RESUMO

OBJETIVO: Avaliar a necessidade de realização da fase de equilíbrio nos exames de tomografia computadorizada de abdome.MATERIAIS E MÉTODOS: Realizou-se estudo retrospectivo, transversal e observacional, avaliando 219 exames consecutivos de tomografia computadorizada de abdome com contraste intravenoso, realizados num período de três meses, com diversas indicações clínicas. Para cada exame foram emitidos dois pareceres, um avaliando o exame sem a fase de equilíbrio (primeira análise) e o outro avaliando todas as fases em conjunto (segunda análise). Ao final de cada avaliação, foi estabelecido se houve mudança nos diagnósticos principais e secundários, entre a primeira e a segunda análise. Foi utilizada a extensão do teste exato de Fisher para avaliar a modificação dos diagnósticos principais (p < 0,05 como significante).RESULTADOS: Entre os 219 casos avaliados, a supressão da fase de equilíbrio provocou alteração no diagnóstico principal em apenas um exame (0,46%; p > 0,999). Com relação aos diagnósticos secundários, cinco exames (2,3%) foram modificados.CONCLUSÃO: Para indicações clínicas como estadiamento tumoral, abdome agudo e pesquisa de coleção abdominal, a fase de equilíbrio não acrescenta contribuição diagnóstica expressiva, podendo ser suprimida dos protocolos de exame.


OBJECTIVE: To evaluate the role of the equilibrium phase in abdominal computed tomography.MATERIALS AND METHODS: A retrospective, cross-sectional, observational study reviewed 219 consecutive contrast-enhanced abdominal computed tomography images acquired in a three-month period, for different clinical indications. For each study, two reports were issued - one based on the initial analysis of non-contrast-enhanced, arterial and portal phases only (first analysis), and a second reading of these phases added to the equilibrium phase (second analysis). At the end of both readings, differences between primary and secondary diagnoses were pointed out and recorded, in order to measure the impact of suppressing the equilibrium phase on the clinical outcome for each of the patients. The extension of the exact Fisher's test was utilized to evaluate the changes in the primary diagnosis (p < 0.05 as significant).RESULTS: Among the 219 cases reviewed, the absence of the equilibrium phase determined change in the primary diagnosis in only one case (0.46%; p > 0.999). As regards secondary diagnoses, changes after the second analysis were observed in five cases (2.3%).CONCLUSION: For clinical scenarios such as cancer staging, acute abdomen and investigation for abdominal collections, the equilibrium phase is dispensable and does not offer any significant diagnostic contribution.
