Summary
Parsonage-Turner syndrome can cause phrenic nerve palsy, leading to diaphragm dysfunction. Diaphragmatic plication effectively managed symptoms in two patients with this condition.
Area of Science:
- Neurology
- Thoracic Surgery
Background:
- Parsonage-Turner syndrome is an idiopathic neuropathy characterized by acute, severe nerve pain and subsequent muscle weakness.
- Phrenic nerve palsy, a complication of this syndrome, can result in diaphragmatic dysfunction and respiratory compromise.
Observation:
- Two patients presented with symptomatic phrenic nerve palsy attributed to Parsonage-Turner syndrome.
- Clinical presentation included respiratory distress secondary to diaphragmatic paralysis.
Findings:
- Both patients underwent diaphragmatic plication as a surgical management strategy.
- The procedure successfully addressed the diaphragmatic dysfunction and alleviated patient symptoms.
Implications:
- Diaphragmatic plication is a viable surgical option for managing phrenic nerve palsy in the context of Parsonage-Turner syndrome.
- This case report highlights the importance of recognizing and treating this specific complication of Parsonage-Turner syndrome.

01:12Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

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...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:18Disorders of the Autonomic Nervous System
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
