2. Pathophysiology: Hobaneng ha Metsi a Batang a Utloa Mollo o tukang (Cold Allodynia)¶

+-------------------------------------------------------------------------+
|     MECHANISM OF CIGUATOXIN COLD ALLODYNIA & MANNITOL RESCUE            |
+-------------------------------------------------------------------------+
|  1. Ciguatoxin (CTX) binds Site 5 on Voltage-Gated Sodium Channels      |
|     (Nav1.6 / Nav1.8) in peripheral C-polymodal nociceptors & A-delta   |
|     cold-sensing nerve fibers                                           |
|  2. Shifts activation voltage to resting potential -> Spontaneous,      |
|     repetitive nerve depolarization whenever skin cools below 24-26 C   |
|     -> Brain interprets cold input as intense BURNING HEAT (Allodynia)  |
|  3. Continuous Na+ influx draws water osmotically into axons and        |
|     myelinating Schwann cells -> Acute Paranodal Schwann Cell Edema     |
+-------------------------------------------------------------------------+
|  HOW INTRAVENOUS 20% MANNITOL (1.0 g/kg) REVERSES ACUTE CIGUATERA:      |
|  * Creates an intravascular osmotic gradient that pulls trapped water   |
|    OUT of swollen Schwann cells and nerve axons at the nodes of Ranvier |
|  * Competitively displaces Ciguatoxin from sodium channel membranes     |
|    and scavenges free hydroxyl radicals generated by nerve ischemia     |
