Summary
Chronic carotid glomitis, an inflammation of the carotid body, was found in 42% of opiate addicts. This condition may stem from immune responses to drug use or associated factors.
Area of Science:
- Pathology
- Immunology
- Toxicology
Background:
- Carotid bodies are crucial chemoreceptors involved in cardiorespiratory regulation.
- Opiate addiction is associated with various systemic complications, but specific effects on carotid bodies are less understood.
Purpose of the Study:
- To investigate the prevalence and immunological profile of chronic carotid glomitis in individuals deceased from opiate intoxication.
- To compare findings with age-matched trauma victims.
Main Methods:
- Autopsy sampling of carotid bodies from 50 opiate addicts and 26 trauma controls (young and older).
- Histological staining (haematoxylin-eosin, azan-Mallory) and immunohistochemistry (CD45, CD3, CD8, CD4, CD20, CD68, CD56).
Main Results:
- Chronic carotid glomitis was observed in 42% of opiate cases and 40% of older trauma cases, but not in young trauma cases.
- Inflammatory infiltrates were primarily composed of T suppressor/cytotoxic lymphocytes (50-80%), with monocytic/macrophagic cells (10%) and B lymphocytes (5-20%).
- Inflammation occurred in subcapsular, interlobular, and perivascular areas.
Conclusions:
- Chronic carotid glomitis is a notable autopsy finding in opiate addiction.
- The condition may result from immune reactions to exogenous substances or drug-induced tissue damage within the carotid body.

01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:23Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
