Background And Aims: Long QT syndrome (LQTS) and coronary artery disease (CAD) are both associated with increased risk of ventricular tachyarrhythmia However, there are limited data on the incremental risk conferred by CAD in adult patients with congenital LQTS. We aimed to investigate the risk associated with CAD and life threatening events (LTEs) in patients with LQTS after age 40 years.

Methods: The risk of LTEs (comprising aborted cardiac arrest, sudden cardiac death, or appropriate defibrillator shock) from age 40 through 75 years was examined in 1,020 subjects from the Rochester LQTS registry, categorized to CAD ( = 137) or no-CAD ( = 883) subgroups.

Article Synopsis
  • Both selective (metoprolol) and nonselective (carvedilol) beta-blockers are used for heart failure (HF), but their impact on rhythm issues in patients with implantable cardioverter-defibrillators (ICD) is not well studied.
  • * This research compared the effects of metoprolol and carvedilol on atrial tachyarrhythmia (ATA) and ventricular arrhythmia (VA) in HF patients with an ICD using data from five major trials.
  • * Results showed that carvedilol was linked to a significantly lower risk of ATA and inappropriate ICD shocks compared to metoprolol, while also suggesting a slight reduction in fast VA risk, although this last finding wasn’t

Purpose: Pelvic floor physical therapy (PFPT) is first-line therapy for treatment of pelvic floor tension myalgia (PFTM). Pelvic floor trigger point injections (PFTPI) are added if symptoms are refractive to conservative therapy or if patients experience a flare. The primary objective was to determine if a session of physical therapy with myofascial release immediately following PFTPI provides improved pain relief compared to trigger point injection alone.

Article Synopsis
  • Current guidelines overlook potential sex differences in the risk of ventricular tachyarrhythmia (VTA), prompting a study focused on women with implantable cardioverter-defibrillators (ICDs).
  • The research analyzed data from 4,506 patients across four major studies, finding that women had a significantly lower cumulative incidence of VTA (17% vs 26% in men) after 3.5 years of follow-up.
  • Key risk factors for VTA in women included the use of amiodarone, Black race, and a history of myocardial infarction, with Black race being the only factor also significantly influencing men’s risk.

Article Synopsis
  • Abdominal wall endometriosis can sometimes turn into a type of cancer called clear cell carcinoma, but this is pretty rare.
  • We don't know much about how this happens or how to treat it, so doctors are still figuring it out.
  • In one case, a patient had clear cell cancer from a scar after surgery, and the doctors removed it and gave her a special medicine called Trastuzumab to help with recovery.

Fecal incontinence often is underreported and can be associated with both social embarrassment and isolation. As patients often do not proactively discuss their symptoms, healthcare providers should screen for this distressing condition. The cause of fecal incontinence often is multifactorial, so no single therapy can guarantee perfect, risk-free outcomes.
