Clinical evaluation of an Er:YAG laser combined with scaling and root planing for non-surgical periodontal treatment
2003
Objectifs: le but de cette etude clinique controlee etait de comparer les traitements de maladie parodontale avancee par une association de laser Er:YAG (KEY II®, KaVo, Germany) et de detartrage et surfacage radiculaire manuels (SRP) avec le laser seul. Materiel & Methodes: 20 patients sains presentant des destructions parodontales moderees a avancees furent traites au hasard en bouche divisee par une association de laser Er:YAG et de detartrage et surfacage radiculaire manuels (SRP) (test) et le laser seul (controle). L'energie utilisee en reglage pour le laser etait de 160 mJ/pulsation a un taux de repetition de 10 Hz. Prealablement au traitement, et 3, 6 etl2 mois apres, les parametres s…
Transobturator suburethral tape in the treatment of stress urinary incontinence: efficacy and quality of life after 5 year follow up.
2013
Abstract Objectives Stress urinary incontinence (SUI) is a highly prevalent dysfunction in middle-aged and elderly women. One recent technique places a sub-urethral tape passed through the transobturator foramen. Efficacy and quality of life were assessed after five years of treatment with the transobturator technique in women suffering SUI. This evaluation followed a previous control at the first year post-intervention. Study design Sixty-three women were assessed five years after operation with the transobturator technique. Additionally, twenty-nine women of these women had undergone pelvic floor reconstruction due to different forms of genital prolapse. Quality of life (QoL) was assessed…
Prospective randomized comparison of conventional instruments and the Harmonic Focus(®) device in breast-conserving therapy for primary breast cancer.
2011
Abstract Background In recent years, surgeons have utilized Harmonic instruments to perform breast cancer resection. Retrospective and prospective studies have demonstrated that the use of this surgical device for mastectomy and axillary dissection can reduce perioperative blood loss, seroma formation, and duration and total amount of drainage. No study has analyzed the feasibility of Harmonic instruments in breast-conserving surgery. We conducted a prospective, randomized clinical trial comparing Harmonic instrument and conventional surgery in the performance of breast-conserving surgery and axillary procedures to determine differences in surgical procedures, postoperative outcome, and com…
Tolerability and efficacy of high-dose furosemide and small-volume hypertonic saline solution in refractory congestive heart failure
2000
Thirty patients aged 65-85 years, with refractory New York Heart Association (NYHA) class IV congestive heart failure (CHF) were treated with an intravenous infusion of furosemide (250-2000 mg/d) and small-volume hypertonic saline solution (150 mL of 1.4-4.6% NaCl) twice a day for 6 to 12 days. A daily fluid oral intake of 1000 mL and previous cardiac therapy were maintained. Clinical signs and symptoms of CHF, such as dyspnea, edema and weakness, improved, as did severity of illness as defined by NYHA class. The infusion was well tolerated. After a 12-month follow-up, 24 patients (80%) were alive and in the NYHA class assigned on discharge from the hospital. This therapeutic combination is…
Force Platform Balance Measures as Predictors of Indoor and Outdoor Falls in Community-Dwelling Women Aged 63-76 Years
2008
Background. Inability to maintain balance while standing increases risk of falls in older people. The present study assessed whether center of pressure (COP) movement measured with force platform technology predicts risk for falls among older people with no manifest deficiency in standing balance. Methods. Participants were 434 community-dwelling women, aged 63-76 years. COP was measured in six stances on a force platform. Following balance tests, participants reported their falls with 12 monthly calendars. Incidence rate ratios (IRR) with 95% confidence intervals (CI) were computed from negative binomial regression models. For the analysis, those with>/=1 fall indoors were coded"indoor fal…
Perinatal exposure to 5-methoxytryptamine, behavioural-stress reactivity and functional response of 5-HT1A receptors in the adolescent rat.
2008
Abstract Serotonin is involved in a wide range of physiological and patho-physiological mechanisms. In particular, 5-HT1A receptors are proposed to mediate stress-adaptation. The aim of this research was to investigate in adolescent rats: first, the consequences of perinatal exposure to 5-metoxytryptamine (5MT), a 5-HT1/5-HT2 serotonergic agonist, on behavioural-stress reactivity in elevated plus maze, open field and forced swim tests; secondly, whether the behavioural effects induced by perinatal exposure to 5MT on open field and forced swim tests were affected by the selective 5-HT1A receptor agonist LY 228729, a compound able to elicit a characteristic set of motor behaviours on these ex…
Bone status in adolescents with type 1 diabetes
2010
Aims The aim of the study was to investigate the potential negative impact of type 1 diabetes on bone status of adolescents. Bone status in adolescents with type 1 diabetes was assessed by means of quantitative ultrasound (QUS) and the influence of metabolic control and other diseaserelated and growth variables was analysed. Methods Group I consisted of 99 pubertal (Tanner ≥2) adolescents (49 female), aged 14.3±2.5 years, diabetes duration 4.6±2.3 years. Controls (group II) were 297 children, matched by sex and age, from a healthy population. The influence of glycated haemoglobin (current: HbA1cD; last year’s mean: HbA1cY; whole duration mean: HbA1cT), diabetes duration, percentage of life …
Five-year results following treatment of intrabony defects with enamel matrix proteins and guided tissue regeneration
2004
Treatment with enamel matrix proteins (EMD) or guided tissue regeneration (GTR) has been shown to enhance periodontal regeneration. However, until now there are limited data on the long-term results following these treatment modalities.The aim of the present clinical study was to present the 5-year results following treatment of intrabony defects with EMD, GTR, combination of EMD and GTR, and open flap debridement (OFD).Forty-two patients, each of whom displayed one intrabony defect of a probing depth of at least 6 mm, were randomly treated with one of the four treatment modalities. The following parameters were evaluated prior to surgery, at 1 year and at 5 years after: plaque index, gingi…
Searching for the right timing of surgical delay: angiogenesis, vascular endothelial growth factor and perfusion changes in a skin-flap model.
2009
Summary Background The angiogenic potential of vascular endothelial growth factor (VEGF) and its oxygen pressure-dependent regulation suggest a strong connection between this growth factor and the ‘delay phenomenon'. In this study we focused on the chronological changes in VEGF concentration and flap perfusion in order to optimise the duration of surgical delay. Methods The VEGF concentration in skin and underlying muscle was measured in oversized, random-pattern flaps on 38 male Sprague-Dawley rats after 3, 5 or 7 days of surgical delay. Additionally, flaps were raised 5 or 7 days past preconditioning. The effect on flap perfusion was measured using indocyanine green fluoroscopy and the si…
Morphological parameters as predictors of successful correction of Class III malocclusion
2001
The aim of the study was to assess pre-treatment cephalometric parameters and measurements of the size of the apical bases as predictors of successful orthodontic correction of Class III malocclusions. Pre- and post-treatment lateral cephalograms and study models of 80 completed Class III subjects were examined to obtain 23 cephalometric parameters taken mainly from the analyses of McNamara and Schwarz, and to measure the size of the apical bases. Success of occlusal correction was evaluated as the percentage change of peer assessment rating score during treatment, which was used as the dependent variable in multivariate statistical analyses testing the predictive value of the parameters as…
