This case report examines the combined use of fibrinogen concentrate, four-factor prothrombin complex concentrate (PCC), and idarucizumab, a specific antidote for dabigatran, to reverse the anticoagulant effects of dabigatran and apixaban-induced coagulopathy. An 86-year-old patient, receiving apixaban therapy, presented to the Emergency Department after intentionally ingesting 50 tablets of dabigatran. The combination therapy contributed to the rapid normalization of coagulation parameters and stabilization of the patient's clinical status without subsequent thromboembolic complications.

Tobacco addiction is the primary preventable factor contributing to global mortality, and nicotine is one of the substances with the greatest potential for addiction. With a strong affinity for the α4β2 subtype receptor, cytisine (CYT) functions as a partial agonist of the acetylcholine nicotinic cholinergic receptor. It counteracts the effects of nicotine without causing any withdrawal symptoms.

The present real-world analysis aimed to evaluate and describe the use of gamma-hydroxybutyric acid (GHB) for alcohol withdrawal syndrome (AWS) in hospitalized patients with diagnosis of liver cirrhosis. An 11-year observational retrospective study on patients affected by liver cirrhosis and alcohol use disorder (AUD) was performed using data from the Medical Toxicology Unit of Careggi University Hospital in Florence (Italy). A multivariate logistic regression was performed to estimate the probability of having a CIWA-Ar 3-4 during hospitalization, an AWS length  > 36 h, a hospitalization > 9 days, and the probability of developing drowsiness.

Background: Bradycardia, renal failure, atrioventricular (AV) node blocking, shock, and hyperkalemia syndrome is a potentially life-threatening clinical condition characterized by bradycardia, renal failure, atrioventricular (AV) node blocking, shock, and hyperkalemia. It constitutes a vicious circle in which the accumulation of pharmacologically active compounds and hyperkalemia lead to hemodynamic instability and heart failure.

Case Presentation: A 66-year-old Caucasian female patient was admitted to the emergency department presenting with fatigue and bradycardia.

Article Synopsis
  • Oleander is a toxic plant with harmful cardiac glycosides that can lead to symptoms mimicking digoxin toxicity, such as gastrointestinal issues and heart problems.
  • An 84-year-old man accidentally ingested an oleander leaf infusion, mistaking it for bay laurel, and experienced symptoms, requiring emergency treatment and monitoring.
  • The case highlights the need for careful clinical evaluation in oleander poisoning, as standard tests may not effectively measure its cardiac glycosides, and prolonged monitoring is crucial for patient safety.

Background: The arterial pressure waveform reflects the interaction between the heart and the arterial system and carries potentially relevant information about circulatory status. According to the commonly accepted 'wave transmission model', the net BP waveform results from the super-position of discrete forward and backward pressure waves, with the forward wave in systole determined mainly by the left ventricular (LV) ejection function and the backward by the wave reflection from the periphery, the timing and amplitude of which depend on arterial stiffness, the wave propagation speed and the extent of downstream admittance mismatching. However, this approach obscures the 'Windkessel function' of the elastic arteries.

Purpose: Obesity clearly increases cardiovascular risk, often inducing high blood pressure (BP), impaired left ventricular (LV) function, and increased arterial stiffness. Intensive weight loss and bariatric surgery induce improvement in hypertension and diabetes for morbid obesity. Carotid artery haemodynamics is a powerful prognostic indicator for stroke and cognitive decline independent of BP.
