Introduction: When Metabolism Becomes an Immune Weapon Cancer is often described as a genetic disease, but its most effective weapons are metabolic. Among them, lactic acid has long been viewed as a metabolic byproduct—an inconvenient consequence of aerobic glycolysis. That…

Introduction: When Oral Therapy Reaches Its Ceiling Pulmonary arterial hypertension (PAH) is a disease that rarely forgives therapeutic hesitation. Despite impressive progress in pharmacology over the past two decades, a subset of patients continues to deteriorate even under aggressive combination…
Introduction: When the First Repair Fails Posterior urethral distraction injuries represent one of the most challenging scenarios in reconstructive urology. These injuries, typically associated with severe pelvic trauma, disrupt not only urethral continuity but also the delicate balance of continence,…
Introduction Liver cancer remains one of the most unforgiving malignancies in modern medicine. Despite decades of progress in oncology, hepatocellular carcinoma continues to claim lives with alarming efficiency, particularly in low- and middle-income countries where access to advanced therapies is…
Introduction: Why Another PDE-5 Inhibitor Still Matters Erectile dysfunction (ED) is one of the most common chronic conditions affecting men worldwide, particularly beyond the fourth decade of life. Despite the availability of several well-established phosphodiesterase type 5 (PDE-5) inhibitors, a…
Introduction: When a Tablet Looks Right but Behaves Wrong Counterfeit medicines represent one of the most underestimated threats to modern healthcare. Unlike dramatic medical emergencies, their damage unfolds quietly: through treatment failure, unpredictable adverse effects, erosion of patient trust, and…
Introduction: When Lower Urinary Tract Symptoms Reflect More Than the Prostate Lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) represent one of the most common chronic conditions affecting aging men. While often dismissed as an inevitable consequence…
Introduction: When Vascular Fragility Meets Vascular Remodeling Pulmonary arterial hypertension (PAH) is a relentlessly progressive disease characterized by pulmonary vascular remodeling, elevated pulmonary vascular resistance, and right ventricular failure. Despite advances in targeted therapies, outcomes remain suboptimal in a subset…
Introduction: The Cost of Caution in Pulmonary Arterial Hypertension Pulmonary arterial hypertension (PAH) is a disease in which time is never neutral. Every delay in effective hemodynamic control allows progressive vascular remodeling, irreversible right ventricular strain, and gradual loss of…
Introduction: Erectile Dysfunction as a Vascular Consequence of Dyslipidemia Erectile dysfunction (ED) in middle-aged and elderly men is rarely an isolated disorder. In modern clinical practice, it is increasingly recognized as a vascular manifestation of systemic metabolic disease. Among the…
Introduction: When Two Rare Diseases Collide Pulmonary arterial hypertension (PAH) is a progressive and life-limiting disease defined by pathological remodeling of the pulmonary vasculature, increased pulmonary vascular resistance, and eventual right ventricular failure. Despite advances in targeted therapies, PAH remains…
