Relationship between anxiety level and radiological investigation. Comparison among different diagnostic imaging exams in a prospective single-center…

2016

Objective: Every patient could feel anxious when he waits in a radiological department to undergo diagnostic exams. The aim of our study is to evaluate the impact of the radiological exams on patient anxiety. Materials and methods: We evaluated 343 patients (mean age 54.83 years) who underwent different types of diagnostic exams in the Department of Diagnostic Imaging at our Hospital from April 2013 to August 2014. We administered to patients the State and Trait Anxiety Inventory Test, which detected with high sensitivity both state anxiety and trait anxiety. A team of clinical psychologists and radiologists evaluated the scores obtained. Results: 83 out of 343 patients were excluded becaus…

Muscle-tendon glucose uptake in Achilles tendon rupture and tendinopathy before and after eccentric rehabilitation: Comparative case reports

2016

Achilles tendon rupture (ATR) is the most common tendon rupture injury. The consequences of ATR on metabolic activity of the Achilles tendon and ankle plantarflexors are unknown. Furthermore, the effects of eccentric rehabilitation on metabolic activity patterns of Achilles tendon and ankle plantarflexors in ATR patients have not been reported thus far. We present a case study demonstrating glucose uptake (GU) in the Achilles tendon, the triceps surae, and the flexor hallucis longus of a post-surgical ATR patient before and after a 5-month eccentric rehabilitation. At baseline, three months post-surgery, all muscles and Achilles tendon displayed much higher GU in the ATR patient compared to…

Evaluation of Risk Stratification Markers and Models in Acute Pulmonary Embolism: Rationale and Design of the MARS-PE (Mainz Retrospective Study of P…

2018

An acute pulmonary embolism (PE) is a crucial event in patients’ life and connected with serious morbidity and mortality. Regarding a high case-fatality rate, early and accurate risk-stratification is crucial. Risk for mortality and complications are closely related to hemodynamic stability and cardiac adaptations. The currently recommended risk-stratification approach is not overall simple to use and might delay the identification of those patients, who should be monitored more closely and may treated with more aggressive treatment strategies. Additionally, some risk-stratification criteria for the imaging procedures are still imprecise. Summarized, the search for the most effective risk-s…

Noncontact monitoring of vascular lesion phototherapy efficiency by RGB multispectral imaging.

2013

A prototype low-cost RGB imaging system consisting of a commercial RGB CMOS sensor, RGB light-emitting diode ring light illuminator, and a set of polarizers was designed and tested for mapping the skin erythema index, in order to monitor skin recovery after phototherapy of vascular lesions, such as hemangiomas and telangiectasias. The contrast of erythema index (CEI) was proposed as a parameter for quantitative characterization of vascular lesions. Skin recovery was characterized as a decrease of the CEI value relative to the value before the treatment. This approach was clinically validated by examining 31 vascular lesions before and after phototherapy.

The appropriateness of colonoscopies at a teaching hospital: magnitude, associated factors, and comparison of EPAGE and EPAGE-II criteria.

2011

Background The growing demand for colonoscopies and inappropriate colonoscopies have become a significant problem for health care. Objectives To assess the appropriateness of colonoscopies and to analyze the association with some clinical and organizational factors. To compare the results of the European Panel of Appropriateness of Gastrointestinal Endoscopy (EPAGE) and the EPAGE-II criteria. Design Cross-sectional study. Setting Endoscopy unit of a teaching hospital in Spain. Patients Patients referred for colonoscopy, excluding urgent, therapeutic indications, and poor cleansing. Main Outcome Measurements Appropriateness of colonoscopies according to the EPAGE criteria. Results From 749 c…

Radiation dose distribution in functional heart regions from tangential breast cancer radiotherapy

2015

Abstract Background and purpose To analyze the distribution of individually-determined radiation dose to the heart and its functional sub-structures after radiotherapy in breast cancer patients treated in Germany during 1998–2008. Material and methods We obtained electronic treatment planning records for 769 female breast cancer patients treated with megavoltage tangential field radiotherapy. All dose distributions were re-calculated using Eclipse with the anisotropic analytical algorithm (AAA) for photon fields, and the electron Monte Carlo algorithm for electron boost fields. Based on individual dose volume histograms for the complete heart and several functional sub-structures, we estima…

Long-term hydrocephalus alters the cytoarchitecture of the adult subventricular zone

2014

Hydrocephalus can develop secondarily to a disturbance in production, flow and/or absorption of cerebrospinal fluid. Experimental models of hydrocephalus, especially subacute and chronic hydrocephalus, are few and limited, and the effects of hydrocephalus on the subventricular zone are unclear. The aim of this study was to analyze the effects of long-term obstructive hydrocephalus on the subventricular zone, which is the neurogenic niche lining the lateral ventricles. We developed a new method to induce hydrocephalus by obstructing the aqueduct of Sylvius in the mouse brain, thus simulating aqueductal stenosis in humans. In 120-day-old rodents (n = 18 per group), the degree of ventricular d…

Polycystic ovarian syndrome: assessment with color Doppler angiography and three-dimensional ultrasonography.

1999

We conducted a three-dimensional ultrasonographic evaluation of the size and structure of the ovaries of women who had clinical and biochemical findings suggestive of polycystic ovary syndrome. We carried out a comparative color Doppler frequency and color Doppler amplitude study of the vascular patterns of these ovaries. This study involved 65 women of reproductive age with polycystic ovary syndrome and 25 eumenorrheic women who were not taking hormonal contraceptives and who had a body mass index below 25 kg/m2. Compared to controls, women with polycystic ovary syndrome had larger ovaries and thicker stroma, increased impedance in the uterine arteries, increased stromal vascularity with d…

Does Uterine Doppler Add Information to the Cerebroplacental Ratio for the Prediction of Adverse Perinatal Outcome at the End of Pregnancy?

2019

<b><i>Objective:</i></b> To evaluate whether the addition of the mean uterine arteries pulsatility index (mUtA PI) to the cerebroplacental ratio (CPR) improves its ability to predict adverse perinatal outcome (APO) at the end of pregnancy. <b><i>Methods:</i></b> This was a prospective study of 891 fetuses that underwent an ultrasound examination at 34–41 weeks. The CPR and the mUtA PI were converted into multiples of the median (MoM) and the estimated fetal weight (EFW) into centiles according to local references. APO was defined as a composite of abnormal cardiotocogram, intrapartum pH requiring cesarean section, 5′ Apgar score <7, n…
