Summary
Critical illness polyneuropathy, a common cause of weakness in intensive care units, is often underdiagnosed. This case report details an unusual presentation involving facial muscles, typically unaffected by this condition.
Area of Science:
- Neurology
- Intensive Care Medicine
- Critical Care
Background:
- Neuromuscular weakness is a frequent complication in intensive care units (ICUs).
- Critical illness polyneuropathy (CIP) is an underdiagnosed cause of this weakness.
- Facial muscle involvement is atypical in CIP.
Purpose of the Study:
- To report an unusual case of critical illness polyneuropathy.
- To highlight the potential for facial musculature involvement in CIP.
- To increase awareness of atypical CIP presentations.
Main Methods:
- Case report presentation.
- Clinical assessment of a critically ill patient.
- Review of relevant literature on critical illness polyneuropathy.
Main Results:
- The patient presented with critical illness polyneuropathy.
- Unusual involvement of facial muscles was observed.
- This presentation deviates from typical CIP manifestations.
Conclusions:
- Critical illness polyneuropathy can present atypically.
- Clinicians should consider CIP even with unusual symptoms like facial muscle weakness.
- Early diagnosis and management of CIP are crucial for patient outcomes.

01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
01:22Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
01:22Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
