Introduction: Electrophysiologic (EP) procedures are typically performed via the femoral venous system, but in some patients, the inferior vena cava (IVC) is unavailable. The hepatic vein has emerged as a viable alternative to femoral access, providing an inferior route that accommodates large sheaths required for better catheter manipulation. Although the percutaneous transhepatic approach has been used successfully in the pediatric population, its use in adults is scarce, with a complication rate of approximately 5%.

Purpose: Intramuscular acton prolongatum is most often used as an alternative for intramuscular or intravenous tetracosactide for ACTH stimulation in some countries. Intramuscular administration of acton prolongatum is cumbersome whereas intended intramuscular acton prolongatum or tetracosactide may often turn subcutaneous. Hence, we compared the subcutaneous ACTH-stimulated steroid profiling with those of the intramuscular routes.

Endovascular embolization is the preferred treatment, typically performed via the transfemoral transvenous route through the inferior petrosal sinus (IPS). However, we present a case and a systematic review of indirect CCF treated through deep orbital puncture of the superior ophthalmic vein (SOV) for embolization.

Background: Salbutamol, a short-acting β-agonist used in asthma treatment, is available in multiple formulations, including inhalers, nebulizers, oral tablets, and intravenous, intramuscular, and subcutaneous routes. Each formulation exhibits distinct pharmacokinetic (PK) and pharmacodynamic (PD) profiles, influencing therapeutic outcomes and adverse effects. Although asthma management predominantly relies on inhaled salbutamol, understanding how these formulations interact with patient-specific characteristics could improve personalized medicine approaches, potentially uncovering the therapeutic benefits of alternative formulations for an individual patient.
