Orthodontic camouflage versus orthognathic surgery for class III deformity: comparative cephalometric analysis
2017
The objective of this study was to compare different cephalometric variables in adult patients with class III malocclusions before and after treatment, in order to determine which variables are indicative of orthodontic camouflage or orthognathic surgery. The cases of 156 adult patients were assessed: 77 treated with orthodontic camouflage and 79 treated with orthodontics and orthognathic surgery. The following cephalometric variables were measured on pre-treatment (T1) and post-treatment (T2) lateral cephalograms: sella-nasion-A-point (SNA), sella-nasion-B-point (SNB), and A-point-nasion-B-point (ANB) angles, Wits appraisal, facial axis angle, mandibular plane angle, upper and lower inciso…
New levothyroxine formulation meeting 95–105% specification over the whole shelf-life: results from two pharmacokinetic trials
2016
Small levothyroxine (L-T4) dose changes can lead to significant clinical effects. To ensure thyroid hormone levels are safely maintained, authorities are increasingly adopting stricter potency specifications for L-T4, the most stringent of these being 95-105% of the labeled dose over the whole shelf-life. Levothyroxine sodium (Euthyrox, Eutirox, Lévothyrox ) has been reformulated, and two studies performed, to ensure bioequivalence to the currently marketed formulation and dosage form proportionality of the new formulation.The bioequivalence study was an open-label, randomized, single-dose, two-period, two-sequence crossover comparing the highest dosage strengths of the currently marketed a…
Effect of desquamative gingivitis on periodontal status: a pilot study
2009
OBJECTIVE: Desquamative gingivitis (DG) represents the gingival manifestation associated with several mucocutaneous disorders and systemic conditions. Little is known of whether or not DG could influence the onset or progression of plaque-related periodontitis. In this study, the potential impact of DG on plaque-related attachment loss and pocket formation has been evaluated. METHODS: A cross-sectional evaluation of 12 patients with DG [eight oral lichen planus (OLP), four mucous membrane pemphigoid (MMP)], never treated for DG lesions or plaque-related periodontitis, was carried out. Probing depth (PD), clinical attachment loss (CAL), fullmouth plaque (FMPS), and bleeding (FMBS) scores wer…
Childhood Victimization by Adults and Peers and Health-Risk Behaviors in Adulthood
2019
AbstractVictimization experienced in childhood has been linked with health-risk behaviors (HRBs) in adulthood. The purpose of this cross-sectional survey was to provide data regarding the HRBs using the ISPCAN Child Abuse Screening Tool Retrospective version (ICAST-R), Spanish version. This aimed to broaden existing knowledge by assessing both being victimized by adults and by peers in a Spanish general population of 348, aged 18–35. Age and timing of the reported victimization were also considered. Victimization: physical, psychological, sexual abuse by adults and/or peers showed a prevalence of 44.54%. Of these, 41.29% reported abuse by both. Children victimized by adults, regardless of t…
Failure to find association between childhood abuse and cognition in first-episode psychosis patients
2012
AbstractThis study investigated the relationship between severe childhood abuse and cognitive functions in first-episode psychosis patients and geographically-matched controls. Reports of any abuse were associated with lower scores in the executive function domain in the control group. However, in contrast with our hypothesis, no relationships were found amongst cases.
Cross-sectional human study of soft tissue chin (STC) thickness in adult patients in relation to sex, facial pattern and skeletal class
2017
Abstract Purpose The aim of this study was to study the relations between the soft tissue chin (STC) and sex, skeletal class, and facial pattern; and to describe the shape and behavior of the STC. Methods 385 non-growing patients were selected, 206 women and 179 men, with a mean age of 28.8 years (SD 4.2). Patients were divided into groups by skeletal class (class I, II or III) and facial pattern (brachyfacial, mesofacial or dolichofacial). STC thicknesses were measured at pogonion (Pg), soft pogonion (Pg′), gnathion (Gn), soft gnathion (Gn′), menton (Me) and soft menton (Me′) in the CBCTs. Results Sexual dimorphism was observed at Pg-Pg′ and Me-Me′. STC thickness was not related to skeleta…
Comparison of physical activity levels in Spanish adults with chronic conditions before and during COVID-19 quarantine
2020
Abstract Background This is the first study analyzing levels of physical activity in a sample of quarantined adults with chronic conditions. The aim of this study was to compare moderate- and vigorous-intensity physical activity levels in Spanish adults with chronic conditions before and during coronavirus disease 2019 (COVID-19) quarantine. Methods A cross-sectional online survey was administered during the COVID-19 quarantine in Spain. A total of 163 participants with chronic conditions (113 females and 47 males; age range 18–64 years) completed the survey. A total of 26 chronic conditions were included. Participants self-reported average minutes/day of moderate and vigorous physical acti…
Anterior limbic alpha-like activity: a low resolution electromagnetic tomography study with lorazepam challenge
2005
Summary Objective To verify findings of an independently regulated anterior limbic alpha band source. Methods In a randomised cross-over study, the spontaneous EEG was recorded in nine healthy subjects after i.v. lorazepam or placebo. Intracerebral current densities within classical frequency bands were estimated with low resolution electromagnetic tomography [LORETA] and compared between groups with t -statistical parametric mapping [SPM{ t }]. A region-of-interest [ROI] based method was used to compare frontal and occipital alpha band activity changes. Results Irrespective of treatment group, local maxima of alpha band power were localised both in the occipital lobe, Brodman area [BA] 18,…
Lower strength of the human posterior patellar tendon seems unrelated to mature collagen cross-linking and fibril morphology
2009
The human patellar tendon is frequently affected by tendinopathy, but the etiology of the condition is not established, although differential loading of the anterior and posterior tendon may be associated with the condition. We hypothesized that changes in fibril morphology and collagen cross-linking would parallel differences in material strength between the anterior and posterior tendon. Tendon fascicles were obtained from elective ACL surgery patients and tested micromechanically. Transmission electron microscopy was used to assess fibril morphology, and collagen cross-linking was determined by HPLC and calorimetry. Anterior fascicles were markedly stronger (peak stress: 54.3 ± 21.2 vs.…
Identification of resources and skills developed by partners of patients with advanced colon cancer: a qualitative study
2018
National audience; Les aidants familiaux jouent un rôle central auprès des patients présentant un cancer de stade avancé. Parmi les proches susceptibles d’apporter une aide aux personnes malades, les conjoints, en raison des liens qui les unissent et parce qu’ils partagent leur vie quotidienne, sont sans doute les plus confrontés à la maladie. Ils sont également majoritairement désignés comme étant l’aidant principal. L’irruption de la maladie et le besoin d’accompagnement qu’elle nécessite, viennent bouleverser en profondeur les différents équilibres structurant leur quotidien et leur organisation. Ils viennent aussi questionner la nature des relations qu’ils entretiennent, dans une divers…
