Yet clinical observations consistently contradicted this narrow view. Not…
Introduction Chemotherapy saves lives—but often at a cost. Among its most dreaded complications lies a quiet, cumulative threat: doxorubicin-induced cardiomyopathy (DIC). Once heralded as an inevitable byproduct of anthracycline therapy, this progressive left ventricular (LV) dysfunction remains a key limitation…
Introduction Connective tissue disease–associated pulmonary arterial hypertension (CTD-PAH) remains one of the most treatment-resistant subtypes of PAH. Despite modern advances, survival outcomes in this group—especially in systemic sclerosis–associated PAH (SSc-PAH)—have historically lagged behind idiopathic PAH. The AMBITION trial, originally designed…
Introduction Endoscopic management of ureteral calculi has evolved into the standard of care for obstructive urolithiasis. However, a fundamental challenge persists: gaining atraumatic access through the lower ureteric orifice (LUO), particularly when using large-caliber ureteroscopes. Excessive ureteral resistance at the…
Introduction Radical prostatectomy remains a cornerstone of curative treatment for localized prostate cancer. Yet, it often exacts a physiological cost: the dual challenges of erectile dysfunction (ED) and urinary incontinence. Even with modern bilateral nerve-sparing techniques (nsRP), recovery of sexual…
Introduction: A Rare Intersection of Two Complex Diseases Pulmonary Langerhans cell histiocytosis (PLCH) occupies a small yet fascinating corner of respiratory medicine. Characterized by the proliferation of CD1a-positive Langerhans cells within the lung parenchyma, PLCH represents a unique smoking-related interstitial…
