Gastric ulcers remain one of the most persistent challenges in modern gastroenterology. Despite decades of research and the availability of proton pump inhibitors (PPIs) and H₂-blockers, the side effects of nonsteroidal anti-inflammatory drugs (NSAIDs) continue to trigger new cases each…

Introduction Few areas of medicine are more delicately balanced between biology, psychology, and social expectation than female sexuality. For decades, clinicians treated low sexual desire or arousal problems in women with vague diagnoses, broad psychotherapeutic strategies, and a trial-and-error approach…

Introduction In the intricate dance of pharmacotherapy, precision is everything. The difference between therapeutic success and clinical failure often rests on a few micrograms of a drug molecule circulating in the plasma. Therapeutic Drug Monitoring (TDM), therefore, is not a…

Introduction Androgen deficiency is a clinical reality that every urologist must learn to navigate with caution and precision. It is far from being a one-size-fits-all diagnosis. Instead, it represents a constellation of endocrine, metabolic, and sexual health issues that overlap…
