By Dr. Marco De Nardin, Anesthesiologist & Intensivist
Evidence-based articles covering the full spectrum of medicine — from common symptoms to advanced procedures.
The medical history is the structured interview that opens the diagnostic process. A doctor explains how it works and why it guides most diagnoses before any test.
A diagnosis is a process, not a moment. A doctor walks through its five stages, from the medical history to the definitive diagnosis.
Pathophysiology explains how a disease alters the way the body works. A doctor shows why understanding disease mechanisms is the key to rational treatment.
Diagnostic tests confirm or rule out a hypothesis the doctor has already formed. Learn the main types and how a physician decides which tests you actually need.
The physical examination is the doctor's hands-on search for objective signs. Learn the four techniques, the famous clinical signs, and what to expect during a visit.
The hypothalamus controls temperature, hunger, sleep, stress, and hormones. Its 7 functions, the hormones it produces, and what happens when it malfunctions.
Explore articles across the ten areas of medicine.
From common infections to chronic illnesses, this section covers the diseases and medical conditions you need to understand. Each article explains what the condition is, how it develops, how it is diagnosed, and how it is treated — written by a physician, with references to current clinical evidence.
Symptoms are what the patient feels — pain, fatigue, dizziness, shortness of breath. Understanding a symptom means understanding which conditions can cause it and when to seek medical attention. These articles explain the clinical reasoning behind common and less common symptoms.
Clinical signs are what the doctor observes during examination — an abnormal heart sound, an enlarged liver, a skin rash with specific characteristics. This section explores the techniques and findings of the physical examination, the physician's most fundamental diagnostic tool.
Blood tests, urine analysis, cultures, and specialized markers — laboratory medicine provides the data that confirms or excludes a clinical suspicion. These articles explain what each test measures, how to interpret the results, and what the reference values mean in context.
X-rays, CT scans, MRI, ultrasound, and nuclear medicine — medical imaging allows physicians to see inside the body without surgery. These articles explain how each imaging technique works, when it is indicated, what it can and cannot show, and how to prepare for the examination.
Understanding medications means understanding how they work, why they are prescribed, and what to watch for. This section covers pharmacological and non-pharmacological therapies — from antibiotics to pain management, from chemotherapy to physical rehabilitation — with the mechanisms of action that make clinical decisions rational.
From minimally invasive injections to major surgery, medical procedures are interventions that go beyond prescribing medication. These articles explain what happens during the procedure, how to prepare, what the risks and benefits are, and what recovery looks like — so patients can make informed decisions.
Prevention is the most cost-effective intervention in medicine. This section covers the three levels of prevention — primary (avoiding disease), secondary (early detection through screening), and tertiary (limiting complications) — along with evidence-based lifestyle recommendations for maintaining health.
Before understanding a disease, you need to understand how medicine thinks. What is a diagnosis? What is the difference between a sign and a symptom? What are risk factors, and what does prognosis mean? These foundational articles provide the conceptual vocabulary that makes every other medical article easier to understand.
Medicine advances through research. This section covers recent findings from major medical journals, clinical trial results, and updated guidelines that change how diseases are diagnosed and treated. Each article translates the research into practical implications for patients and healthcare professionals.
