Immune-checkpoint inhibitors (ICI) have revolutionized cancer therapy but are associated with infrequent but lethal myocarditis, for which management remains uncertain. Abatacept, a CTLA-4 fusion protein targeting CD86 on antigen presenting cells and leading to global T-cell anergy, has been described as a potential treatment in individual reports. Yet, abatacept treatment dosage, schedule and optimal combination with other immunosuppressive therapies are unclear.

It encompasses the prevention and treatment of cardiovascular toxicities related to cancer treatments, aiming to reduce cardiac adverse events among cancer survivors. Cardiovascular toxicities related to cancer treatments are described through data collected during phase I to phase III therapeutic trials, and post-marketing surveillance (phase IV).

Androgens shorten QT, which may be protective against acquired long QT syndromes and their related arrhythmias in men such as torsade de pointes (TdP). On the other hand, androgens can potentiate Brugada and early repolarization syndromes, which are most prevalent in men.
View Article and Find Full Text PDFImmune checkpoint inhibitors (ICI) have constituted a paradigm shift in the management of patients with cancer. Their administration is associated with a new spectrum of immune-related toxicities that can affect any organ. In patients treated with ICI, cardiovascular toxicities, particularly myocarditis, occur with a low incidence (<1%) but with a high fatality rate (30-50%).

Methods: We performed a population-pharmacokinetic analysis from 104 consecutive COVID-19 hospitalized patients (31 in intensive care units, 73 in medical wards, n=149 samples). Plasma HCQ concentration were measured using high performance liquid chromatography with fluorometric detection.

Introduction: Type 1 thyroplasty is performed to improve glottis closure as well as dysphagic symptoms in patients with unilateral vocal fold immobility.
Objectives: This study aims to compare the motility of the pharynx and upper esophageal sphincter in patients with unilateral vocal fold immobility before and after thyroplasty Type I.
Methods: We prospectively studied 15 patients with unilateral vocal fold immobility who underwent thyroplasty Type I.
The motility of the pharynx, upper esophageal sphincter (UES), and proximal esophagus in patients with oropharyngeal dysphagia is still not entirely understood. High-resolution manometry (HRM) was recently added to the armamentarium for the study of this area. This study aims to describe HRM findings in patients with vagal paralysis.

This study aims to determine sensitivity and specificity of symptoms, nasal endoscopy, and laryngoscopy for the diagnosis of GERD as compared to pH monitoring.
Methods: We studied 79 patients (mean age 53 years, 38 % males) in whom ENT symptoms were assumed to be secondary to GERD.
Unlabelled: The ideal approach for the treatment of glottal insufficiency remains a challenge for laryngologists.
Aim: This experimental study assessed the histological changes and fibrosis caused by autologous fascia lata grafts into the rabbit voice muscle.
Study Design: A clinical and experimental study.
Unlabelled: Proper diagnosis of laryngeal benign lesions still brings doubts among experienced laryngologists, despite current diagnostic progress.
Aim: The goal of this study was to compare telelaryngoscopy (preoperative) with suspension laryngoscopy (intraoperative) on the diagnosis of vocal fold benign lesions.
Materials And Methods: We carried out a restrospective study analyzing 79 charts from patients followed up in a University Hospital.
