BACKGROUND About 1/4 of patients with hypertrophic cardiomyopathy (HCM) seem to develop atrial fibrillation (AF) over their life-span. Typically, symptoms of heart failure and especially shortness of breath get much worse once AF is present. Catheter ablation of AF in HCM has been proposed by several centres, but outcomes are much worse than in non-HCM AF. Accurate mapping of the arrhythmia is crucial with regard to improving the procedural outcome. Interestingly, intracardiac mapping during AF has demonstrated very long average cycle length during ongoing AF in HCM which should make identification of the critical re-entry/rotors much easier using dipole cardiac mapping (Acutus mapping system, Acutus Medical, CA, USA). POPULATION and PURPOSE This is a pilot trial recruiting a total of 20 patients with HCM and AF (paroxysmal or persistent with <12 months duration time in persistent AF) eligible for catheter ablation, without other significant structural heart disease Primary endpoints Safety: Absence of acute adverse events due to the use of ACUTUS mapping system during AF ablation Evidence of chronic adverse events due to the use of ACUTUS mapping system guided catheter ablation during the 12 months F/U period Safety endpoint of the entire mapping and ablation strategy Efficacy: Assessment on efficacy of ACUTUS mapping system guided AF ablation in HCM patients using a double-arm study design RF time to termination of AF to SR Secondary endpoints RF time to termination of AF to atrial tachycardia (AT) Freedom from AF/flutter/tachycardia (> 30 sec) at the end of the 12 months follow up (F/U) period Time to first recurrence of AF/flutter/tachycardia (> 30 sec) Freedom of AF/flutter/tachycardia on previously failed anti-arrhythmic medication Ablation procedure First 10 patients (group 1): ablation will be carried out after acquisition of a left atrium (LA) and right atrium (RA) dipole map at baseline, pre and post administration of Adenosine IV. Then pulmonary vein isolation (PVI) as a first step and subsequent remap and ablation of all patterns of interest in the LA until restoration of sinus rhythm (SR) or decision to proceed with direct current cardioversion (DCCV, 360J). Second 10 patients (group 2): after the acquisition of a dipole map of LA and RA at baseline (pre and post Adenosine IV administration), ablation of all identified areas of interest (API) will be performed, followed by remap and finally PVI +/- DCCV. For all patients: final step will be the deployment of a RA isthmus line and demonstration of bidirectional block. FOLLOW UP Patients will be followed up at 3, 6, and 12 months.

Gingival enlargement is one of the most common soft tissue problems associated with fixed orthodontic treatment. The presence of orthodontic appliances impedes oral hygiene measures and alters the oral microbial ecosystem to a more pathogenic oral biofilm. Subsequent accumulation of plaque can contribute to development of chronic periodontal inflammation and can progress to gingival enlargement. Gingival enlargement inhibits hygiene measures, slows down orthodontic tooth movement and cause aesthetic and functional problems. Management of gingival enlargement by non-surgical periodontal treatment is considered to be most important and effective. Optimal plaque control can be maintained by meticulous brushing, flossing and professional scaling. However, motivation of maintaining oral hygiene can be disappointing in some patients. In cases that the enlarged gingivae became fibrous, surgical treatment can be considered. Traditionally, gingivectomy was performed using scalpel under local infiltration. Since the first laser designed for dental use was introduced in 1989. Laser technology has continuously developed over the years and there are now many different types of dental lasers using a variety of wavelengths, e.g. Diode, Er:YAG, CO2 and Er,Cr:YSGG lasers. In orthodontics, various intraoral soft tissues surgical procedures may be required frequently, e.g. gingivectomy, gingivoplasty, fraenectomy, exposure of unerupted/ impacted/ partially erupted teeth. The use of laser has becoming more popular because the advantages of laser therapy are good haemostasis, excellent visualization of the operating field, fewer intra- and post-operative complications, bactericidal effect, no suture required, less scars, and better pain control with effects of reduced use of local anaesthesia and analgesic. Diode laser unit has the merits of compact size and relatively low price. Gingivectomy by diode laser may become an effective adjunctive treatment in orthodontic practice. The aim of this study was to evaluate the clinical effectiveness of diode laser in the management of gingival enlargement related to orthodontic treatment.

The purpose of this study is to identify the patients seen in our practice who are seen with Hypertrophic Myopathy diagnosis in order to better understand the presenting characteristics of their disease, the diagnostic testing to determine the diagnosis, the methods used to follow the disease progression and management practices used in caring for these patients. The objectives of this data review will be an analysis to determine if there is a methodology that will foster improved diagnostic speed and accuracy, and determine the best management practices based on outcomes in these patients.

The consequence of aortic valve stenosis (AVS) is increased pressure load on the left ventricle which causes left ventricular (LV) hypertrophy, and myocardial stretch will cause activation of cardiac peptides and activation of the renin angiotensin aldosterone system (RAAS). The consequence of LV hypertrophy is increased chamber-stiffness and delayed active LV relaxation which initially will cause diastolic and later systolic dysfunction. In heart failure (HF) and ischemic heart disease the degree of diastolic dysfunction has been demonstrated to correlate with functional class, neurohormonal activation and prognosis which also recently have been suggested for AVS. With longstanding elevated filling pressures the left atrium (LA) will dilate. Only limited data are available on the degree and importance of LA dilatation in AVS. When apparent, symptoms of HF in AVS are associated with high mortality rates. If LV systolic dysfunction also is present prognosis will deteriorate further. In these cases aorta valve replacement (AVR) is recommended. AVR will normalize pressure overload and thereby decreases LV hypertrophy. Previously it was believed that in time LV hypertrophy regressed towards normal and even normalized. Recent studies however have demonstrated that LV hypertrophy regression mainly happens during the first year after AVR, and little subsequent changes are seen during the remaining 10 years. Furthermore, patients that experience most regression of hypertrophy have more favourable outcome and better functional class than patients with less regression of hypertrophy. Thus absence of reverse remodelling is associated with poor outcome after AVR. Importantly the regression of LV hypertrophy is closely paralleled by decreasing RAAS hyperactivity. RAAS hyperactivity may be attenuated pharmacologically with angiotensin II receptor blockers (ARB) which in systemic hypertension with LV hypertrophy has been associated with reverse remodelling. The hypothesis is that in patients undergoing AVR for symptomatic AVS, 12 months post operative blockade of the angiotensin II receptor will accelerate LV and LA reverse remodelling, reduce filling pressures and suppress neurohormonal activation compared with conventional therapy. This will lead to improved exercise tolerance and due to improved left atrial function reducing the risk of atrial arrythmias.

There are indications that phosphatidic acid (PA) supplementation is capable of enhancing gains in strength and muscle mass in response to strength training, although the literature is still incipient and controversial. Given the possible benefits in terms of maintenance and increased skeletal muscle mass, which still need confirmation, this study aims to examine the effectiveness of PA supplementation in two different doses in increasing skeletal muscle mass and strength in adult men undergoing to 8 weeks of strength training. For this, about 45 men will be randomly allocated to one of three treatments at a ratio of 1:1:1: PA 750mg per day, PA 375mg per day, or placebo (cornstarch, 750mg per day). All participants will undergo a 8-week strength training program, 3 times a week, totaling 24 sessions, which will begin with the start of supplementation. Individuals will be assessed for maximum dynamic strength of upper and lower limbs, resistance to dynamic strength of upper and lower limbs, body composition, muscle cross-sectional area and food consumption. Samples of venous blood will also be collected to determine the concentration of creatine kinase (CK), lactate dehydrogenase (LDH), testosterone, insulin-like growth factor type 1 (IGF-1), growth hormone (GH) and cortisol. These evaluations will be carried out before (PRE) and after (POST) the period of supplementation and training. Additional blood samples will be taken 48 hours after the first and last training sessions, for specific determination of blood muscle damage markers: CK and LDH.
