Introduction Vancomycin is a prominent glycopeptide antibiotic widely recognized for its efficacy in treating severe infections caused by Gram-positive bacteria, particularly methicillin-resistant Staphylococcus aureus (MRSA) and certain Clostridioides difficile (C. diff) infections. Its critical role in modern medicine stems from an increasing need to address challenging and resistant microbial pathogens that threaten patient safety in … Read more
Introduction Inflammatory Bowel Disease (IBD) is a chronic, relapsing-remitting inflammatory disorder of the gastrointestinal tract that primarily includes Crohn’s disease (CD) and ulcerative colitis (UC). Both conditions can produce significant morbidity, including abdominal pain, diarrhea (often with blood), weight loss, and systemic manifestations such as anemia. Thought to arise via an intricate interplay of genetic … Read more
Introduction Irritable Bowel Syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain and altered bowel habits in the absence of any identifiable structural or biochemical abnormalities. IBS affects an estimated 5-15% of the global population, placing a considerable burden on healthcare systems and patients’ quality of life. Despite ongoing research, IBS remains … Read more
I. Introduction Gastroesophageal reflux disease (GERD) is a chronic disorder characterized by the reflux of gastric contents into the esophagus, which leads to troublesome symptoms, mucosal injury, and, in some cases, serious complications such as strictures or Barrett’s esophagus. GERD is one of the most prevalent GI disorders globally, affecting up to 20% of adults in … Read more
Introduction Peptic Ulcer Disease (PUD) is a gastrointestinal disorder characterized by sores or lesions in the lining of the stomach or duodenum. It is a significant health concern worldwide, affecting a broad demographic. Pathophysiology Peptic ulcers result from an imbalance between mucosal defensive factors (like mucus and bicarbonate secretion) and aggressive factors (such as gastric … Read more
Introduction Helicobacter pylori (H. pylori) is a spiral-shaped, gram-negative bacterium that colonizes the human stomach and duodenum. First identified in the early 1980s, this organism quickly garnered attention due to its critical role in the pathogenesis of peptic ulcer disease, chronic gastritis, and certain types of gastric malignancies, notably gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) … Read more
I. Definition, Historical Perspective & Epidemiology Zollinger–Ellison Syndrome (ZES) is a rare disorder characterized by gastrin-secreting tumors (“gastrinomas”) of the pancreas or duodenum. These tumors lead to excessive gastric acid secretion, resulting in recurrent, treatment-resistant peptic ulcers, severe gastroesophageal reflux, and diarrhea. II. Pathophysiology 1. Gastrinoma Biology 2. Mechanism—Gastrin Overproduction 3. Resultant Clinical Effects III. Clinical … Read more
1 · Introduction Pharmacovigilance (PV) is the “science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other medicine-related problem” (WHO). In an era of precision medicine, globalised supply chains and accelerated approvals, PV has become indispensable for safeguarding patients throughout the therapeutic life-cycle—from first-in-human dosing to decades of post-marketing … Read more
Oxytocin, a neuropeptide hormone produced by the hypothalamus and secreted by the posterior pituitary gland, has garnered significant attention in recent years due to its diverse physiological and psychological effects. Often referred to as the “love hormone” or “cuddle chemical,” oxytocin plays a crucial role in social bonding, sexual reproduction, and maternal behaviour. This article … Read more
I. Introduction Tocolytic agents are medications used to inhibit uterine contractions and suppress premature labor, thereby prolonging pregnancy long enough for vital fetal benefits—particularly the administration of antenatal corticosteroids and safe transfer to an appropriate facility. Modern practice focuses on maximizing neonatal outcomes while minimizing maternal and fetal risks, as no tocolytic is conclusively shown to … Read more
