Systemic side effects of anti-cancer therapy remain a major limiting factor for patients, even with targeted therapy. Bevacizumab is an example of targeted cancer therapy which targets the vascular endothelial growth factor receptor (VEGFR) that has been approved for the treatment of various cancers and has been evaluated in metastatic urothelial carcinoma (MUC). We report a case of MUC on bevacizumab containing regimen who developed temporary asymptomatic sinus bradycardia with sinus pauses. That adverse event was thought to be related to the bevacizumab in her cancer regimen. Her Holter monitoring recording for a total duration of 28 days and 14 h after discharge did not show recurrence of sinus pauses. This case indicates the necessity for observation for the cardiac conduction defects as side effects in patients receiving bevacizumab, especially since they might be asymptomatic and transient.

Severe bradycardia in patients with obstructive sleep apnoea and good early response to CPAP.
Sleep Breath
January 2025
Department of Cardiac and Vascular Diseases, Jagiellonian University Medical College, John Paul II Hospital, Prądnicka 80, Kraków, 31-202, Poland.
Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.
Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.
Intermittent Sinus Pause/Asystole in the Setting of Anticholinergic Overdose.

January 2025
Emergency Medicine, Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo, USA.
Anticholinergic toxicity typically presents with symptoms of cutaneous vasodilation, delirium, mydriasis, urinary retention, hyperthermia, anhidrosis, and tachycardia. This case report presents a 68-year-old female patient who exhibited some of these signs and symptoms after ingesting an unknown quantity of dicyclomine. However, she displayed one notable exception to the classic toxidrome.

January 2025
Department of Cardiology, Edgardo Rebagliati Martins National Hospital, Avenida Edgardo Rebagliati 490, Jesús María, Lima 15072, Perú.
Background: This case report highlights the conduction disorder anomalies associated with dengue infection, particularly bradyarrhythmias due to dysfunction of the sinus node and atrioventricular node, which may require cardiac stimulation such as pacemaker implantation. This case emphasizes the importance of continuous monitoring and the use of additional diagnostic techniques to detect complications in a timely manner.
Case Summary: A 31-year-old male patient was admitted to our institution with symptoms of dyspnoea, orthopnoea, and severe bradycardia.
Xylometazoline-induced change in aspirated nasal nitric oxide detects obstructed paranasal ostia.
J Breath Res
January 2025
Faculty of Medicine and Health Technology, Tampere University, Arvo Ylpön Katu 34, 33520 Tampere, Finland.
The concentrations of nasal nitric oxide (nNO) vary in patients with chronic rhinosinusitis (CRS) supposedly depending upon whether the paranasal ostia are open or obstructed. Our aim was to assess whether nNO levels and their response to topical xylometazoline (a local vasoconstrictor used to alleviate nasal congestion) in patients with CRS differ between those with open or obstructed ostia and if the results were altered by the use of nasal corticosteroids. Sixty-six patients with CRS (43% with nasal polyps) or recurrent acute rhinosinusitis and 23 healthy controls were included.

December 2024
Division of Cardiology, Cardio-Thoracic Department, University Hospital of Verona, Verona, Italy.
Background: Implantable loop recorders (ILRs) have been shown to significantly improve the detection of atrial fibrillation (AF) in patients with embolic stroke of undetermined source (ESUS). The incidence and characterization of bradyarrhythmias in this subset of patients is still unknown.
Methods: All consecutive patients who received ILRs, after an ESUS, between March 2015 and December 2022 in our Center were retrospectively enrolled and analyzed.
