According to your sources, Diffuse Axonal Injury (DAI) is widespread axonal damage caused by the physical forces of a mild, moderate, or severe traumatic brain injury (TBI) [1]. Physical Mechanism Traumatic Impact Forces : DAI occurs due to the tensile forces of trauma sustained during a head injury[1]. Cellular Progression : Rather than immediate shearing or tearing of the axon at the moment of i...

Core Intracranial Dynamics (The 20%) Volume Distribution : The enclosed skull holds 78% brain tissue, 12% blood, and 10% CSF [1][2]. Monro-Kellie Doctrine : Intracranial volume is constant; an increase in any component requires compensatory displacement of others to maintain constant volume within the skull[2]. Key Clinical Target Values : Normal ICP is 5–15 mm Hg (sustained >20 mm Hg is abnorm...

An Epidural Hematoma (EDH) and a Subdural Hematoma (SDH) are two distinct forms of focal intracranial bleeding caused by head trauma[1][2]. They differ significantly in anatomical location, primary bleeding source, clinical progression, and at-risk populations[2][3]. 1. Side-by-Side Comparison FeatureEpidural Hematoma (EDH)Subdural Hematoma (SDH)Anatomical Location Between the dura mater and the i...

Burn Classification & TBSA Assessment Burn severity depends on depth, extent (TBSA), location, and patient risk factors[1]. Depth is classified as partial-thickness (epidermal/dermal; painful, red, blistered) or full-thickness (dermal destruction, painless, leathery eschar, visible thrombosed vessels)[2]. TBSA is estimated using the Rule of Nines for adults or the Lund-Browder chart for childr...

Primary Headaches[1] Tension (TTH): Bilateral, dull bandlike pressure[1][2]. No nausea[2]. Tx: NSAIDs[3][4]. Prev: Amitriptyline[3][5]. Migraine: Unilateral throbbing, ± aura[1][6]. Triggers: stress, red wine[6][7]. Acute: Triptans (sumatriptan; contraindicated in CAD, ischemic stroke, uncontrolled HTN)[5]. Prev: Topiramate, β-blockers, Botox[3]. Cluster: Severe unilateral orbital pain in clusters...

80/20 Clinical Stroke Summary Core Concepts & Emergency Recognition A stroke is an emergency where cell death occurs due to ischemia (inadequate blood flow, 87% of cases) or hemorrhage (bleeding, 13%)[1][2]. Interruption of blood flow alters brain metabolism in 30 seconds, stops it in 2 minutes, and causes cell death in 5 minutes[3]. The FAST protocol is critical for rapid recognition: F ace d...

80/20 Clinical Summary: Renal Failure (AKI vs. CKD) 1. Pathophysiology AKI: Sudden, potentially reversible decline in GFR[1]. Prerenal: Decreased perfusion (hypovolemia, shock, HF). Oliguria occurs without tissue damage; reversible with fluids[1][2]. Intrarenal: Direct tissue damage, 90% from Acute Tubular Necrosis (ATN) (ischemia, sepsis, nephrotoxins)[2]. Postrenal: Mechanical obstruction (BPH,...

80/20 Neurological Assessment & Physiology Summary 1. Structure & Cellular Biology Organization: The CNS consists of the brain, spinal cord, and CN I-II[1]. The PNS contains CN III-XII, spinal nerves, and the ANS[1]. Cells & Myelin: Neurons conduct action potentials via saltatory conduction across nodes of Ranvier, accelerated by myelin[2]. Astrocytes form the blood-brain barrier and c...

Clinician’s 80/20 Hematologic & Anemia Summary Core Clinical Concepts Blood disorders disrupt homeostasis. Key pathological threads include: Fatigue : Secondary to tissue hypoxia (anemia, cancer). Infection Risk : Compromised immunity and risk for infection is a major concern in hematologic cancers and a common side effect of therapy. Pain : Common and classic in sickle cell disease (SCD) and...

. DM Classification & Core Diagnostics Type 1 DM : Autoimmune β-cell destruction (HLA-DR3/DR4) causing absolute insulin deficiency; presents abruptly with classic 3 Ps (polyuria, polydipsia, polyphagia), weight loss, and DKA risk[1][2]. Type 2 DM : Insulin resistance combined with relative β-cell deficiency and inappropriate hepatic glucose production[3]. Onset is gradual[4]. Diagnostic Criter...

Urinary System: 80/20 Summary 1. Anatomy & Blood Supply The upper urinary tract has two retroperitoneal, bean-shaped kidneys (T12–L3) and 2 ureters[1]. The lower tract comprises the bladder and urethra[1]. Each kidney is shielded by a fibrous capsule and cushioned by fat[1]. The functional unit is the nephron (~1 million), consisting of a glomerulus, Bowman's capsule, and tubule system (PCT, l...

80/20 Comparative Summary: Amiodarone vs. Lidocaine 1. Class & Mechanism of Action Amiodarone (Cordarone): Class III antiarrhythmic with Class I, II, III, and IV actions[1][2]. Primarily blocks potassium channels in phases 2 and 3, delaying repolarization and prolonging effective refractory period[1]. Weakly blocks sodium channels (phase 0 upstroke), depresses SA/AV automaticity, blocks calciu...

80/20 Summary: Pediatric Cardiac Arrest Recognition & Management 1. Core Pathways & Immediate Recognition (High-Impact 20%) Pathways to Arrest : Most pediatric cardiac arrests stem from progressive hypoxic/asphyxial respiratory failure or shock rather than sudden cardiac collapse[1][2]. Out-of-hospital arrest (OHCA) survival is ~8%, whereas in-hospital (IHCA) survival reaches ~43%[1][3]. I...

80/20 Summary: Pediatric Respiratory Emergency Management Respiratory failure causes most pediatric cardiac arrests[1]. Prompt management via the Evaluate-Identify-Intervene cycle restores oxygenation and ventilation before collapse[1][2]. 1. Core Life-Support & Initial Management Rescue Breathing : For respiratory arrest with a pulse, give 12–20 breaths/min (1 breath every 3–5 seconds), each...

80/20 Summary: Pediatric Arrhythmia Management & Algorithms [1] 1. Core Assessment & Stability Principles Hemodynamic Instability: Recognized by respiratory failure, shock with poor end-organ perfusion (with or without hypotension), altered mental status/irritability, chest pain, or sudden collapse[1]. Initial Actions: Support ABCs, give high-concentration O₂, attach ECG/oximetry/BP monito...

80/20 Core Need-to-Know Principles Cardiac Output Formula : Cardiac output equals stroke volume times heart rate ($CO = SV \times HR$)1. Because young children cannot increase stroke volume significantly, bradycardia directly drops cardiac output2. Leading Cause of Bradycardia : Tissue hypoxia from hypoxemia or respiratory failure is the main cause of symptomatic bradycardia1. Supporting airway, o...
