Indeterminate focal liver lesions incidentally discovered at gray-scale US: role of contrast-enhanced sonography.
2011
OBJECTIVES: to assess the role of contrast-enhanced ultrasound (CEUS) in the characterization of focal liver lesions (FLLs) incidentally discovered but indeterminate at gray-scale ultrasound (US). MATERIALS AND METHODS: one hundred forty-two consecutive patients with 174 FLLs (169 benign and 5 malignant) incidentally discovered but indeterminate at gray-scale US, underwent CEUS after the administration of SonoVue. Two readers independently reviewed CEUS scans and: (1) classified each lesion as malignant or benign on a 5-point scale of confidence by means of definite diagnostic criteria; (2) provided if possible a specific diagnosis; (3) were requested if further imaging was needed for lesio…
Executive function and metacognitive self-awareness after severe traumatic brain injury.
2008
The objective of this study is to identify the clinical, neuropsychological, neuropsychiatric, and functional variables that correlate with metacognitive self-awareness (SA) in severe traumatic brain injury (TBI) outpatients and to assess the influence of the same variables on the sensory-motor, cognitive, and behavioral-affective indicators of SA. This cross-sectional observational study evaluated 37 outpatients from May 2006 to June 2007 in a neurorehabilitation hospital on the basis of the following inclusion criteria: (1) age ≥ 15 years; (2) diagnosis of severe TBI (Glasgow Coma Scale, GCS ≤ 8); (3) posttraumatic amnesia (PTA) resolution; (4) capacity to undergo formal psychometric eval…
Cross-cultural adaptation of the orthognathic quality of life questionnaire (OQLQ) in a Brazilian sample of patients with dentofacial deformities
2010
Objectives: The aim of this study is to translate into Portuguese-Brazilian language and adapt cross-culturally to the Brazilian population the Orthognathic Quality of Life Questionnaire (OQLQ). Study Design: The cross-cultural adaptation process followed six stages which are; (I) initial translation, (II) synthesis of the translation, (III) back translation, (IV) expert committee and (V) test of the prefinal version. For validation process, the OQLQ results were compared with Oral Health Impact Profile Questionnaire (OHIP-49), with the generic SF-36 Quality of Life Questionnaire and a visual analogue scale. A convenience sample of 25 patients was selected in two Southern Brazilian states o…
Rome consensus conference - statement; human papilloma virus diseases in males
2013
Background Human Papillomavirus (HPV) is a very resistant, ubiquitous virus that can survive in the environment without a host. The decision to analyse HPV-related diseases in males was due to the broad dissemination of the virus, and, above all, by the need to stress the importance of primary and secondary prevention measures (currently available for women exclusively). The objective of the Consensus Conference was to make evidence-based recommendations that were designed to facilitate the adoption of a standard approach in clinical practice in Italy. Methods The Sponsoring Panel put a series of questions to the members of the Scientific Committee who prepared a summary of the currently av…
Effects of prolonged hypertrophic resistance training on acute endocrine responses in young and older men.
2015
The present study investigated changes in acute serum hormone responses to a resistance exercise bout following a prolonged period of hypertrophic resistance training in young (YM) and older men (OM). Subjects performed a 5 × 10RM leg press exercise protocol before and after 20 weeks of hypertrophic resistance training. In YM, the acute responses in growth hormone were greater compared with before training (p < .05), and cortisol concentration did not increase after training. Endocrine responses in OM were similar before and after training. Greater acute growth hormone responses after training were associated with larger gains in lean mass in the entire subject group (r = .596, p = .019)…
The role of genetics and environment in lifting force and isometric trunk extensor endurance.
2004
Background and Purpose. Our understanding of what different back performance tests are measuring is limited. The purpose of this study was to investigate the relative contributions of genetics and unique and common environmental factors for 3 tests of back muscle performance in a classic twin analysis. Subjects. The subjects were a population-based sample of 122 monozygotic and 131 dizygotic male twin pairs aged 35 to 69 years (X̄=49.9, SD=7.7). Methods. Variance component analysis was applied to estimate genetic and environmental influences on isokinetic and psychophysical lifting and isometric trunk extensor endurance test performance. The Cholesky decomposition genetic factor model was u…
Value of Home Blood Pressures as Predictor of Target Organ Damage in Mild Arterial Hypertension
2002
Home blood pressure measurement has gained increasing importance for the management of hypertensive patients. The aim of our study was to compare levels of clinic (CBP), ambulatory (ABP), and home blood pressure (HBP) measurements, and their relationships with various indexes of target organ damage in I-II grade essential hypertension.Thirty-eight essential hypertensives underwent evaluation of clinic, ambulatory and home blood pressures. Each patient recorded HBP for 2 days with a digital BP monitor three times daily, the first time on the same day during which ABP monitoring was simultaneously performed. Moreover, in all subjects electrocardiogram recording, echocardiographic study, micro…
Neuropsychological Impairments in Anorexia Nervosa: A Spanish Sample Pilot Study
2014
This work was aimed at obtaining a profile of neuropsychological impairments in young Spanish participants with anorexia nervosa (AN) to demonstrate that right-hemisphere and frontal capacity impairments are present not only in the acute phase but also after weight recovery in a Spanish sample compared with a healthy control group. Twelve patients with AN in the acute phase (body mass index [BMI]= 17) matched by age, IQ, and educational level by utilizing a wide neuropsychological battery. Differences were found between AN groups only for long-term verbal memory, which worsens as BMI increases. Among participants with AN as a group, results showed differences in speed of information process…
Immunization Campaigns and Strategies against Human Papillomavirus in Italy: The Results of a Survey to Regional and Local Health Units Representativ…
2019
Objective. The study aimed to assess the impact of HPV immunization campaigns organizational aspects, the characteristics of immunization program (vaccination targets and type of offer), and communicative strategies adopted by four Italian administrative regions on vaccination coverage observed. Methods. From November 2017 to March 2018, regional and Local Health Units (LHUs) representatives were invited to complete an online survey including 54 questions evaluating vaccination invite systems, access systems to vaccination centres, reminder and recall systems, and adverse events surveillance. An overall descriptive analysis was conducted. Since observed vaccine coverage (VC) obtained in fem…
Implant treatment in atrophic posterior mandibles: Vertical regeneration with block bone grafts versus implants with 5.5-mm intrabony length
2014
Purpose: To retrospectively compare the outcomes of implants placed in posterior mandibles vertically regenerated with onlay autogenous block bone grafts and short dental implants. Materials and Methods: Consecutive patients with vertical bone atrophy in edentulous mandibular posterior regions (7 to 8 mm of bone above the inferior alveolar nerve) were treated with either implants placed in regenerated bone using autologous block bone grafts (group 1) or short implants (with 5.5-mm intrabony length) in native bone (group 2) between 2005 and 2010 and followed for 12 months after loading. The procedure used was the established treatment protocol for this type of patient at the Oral Surgery Uni…
