Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin01:26

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

656
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...

Parkinson's Disease: Treatment

222
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Skeletal Muscle Relaxants: Therapeutic Uses01:31

Skeletal Muscle Relaxants: Therapeutic Uses

466
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Skeletal Muscle Relaxants: Adverse Effects01:21

Skeletal Muscle Relaxants: Adverse Effects

337
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

887
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Centrally Acting Muscle Relaxants: Therapeutic Uses01:24

Centrally Acting Muscle Relaxants: Therapeutic Uses

629
Centrally acting muscle relaxants reduce muscle tone and tension by interfering with the postsynaptic reflexes in the central nervous system.
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...

Area of Science:

  • Neurology
  • Movement Disorders
  • Machine Learning in Medicine

Background:

  • Cervical dystonia (CD) is the most common focal dystonia.
  • Approximately one-third of CD patients experience co-existing head and hand tremor.
  • Accurate tremor assessment is clinically challenging, impacting CD diagnosis and treatment.

Purpose of the Study:

  • To identify clinical features predicting the presence and characteristics of neck tremor in a large cohort of cervical dystonia patients.
  • To utilize machine learning for analyzing complex clinical data in CD.

Main Methods:

  • Analysis of the largest available cervical dystonia patient cohort (n=3117) from 37 centers worldwide.
  • Application of machine learning algorithms to predict tremor presence and regularity based on clinical features.

Main Results:

  • 1,367 out of 3,117 CD patients had neck tremor, with varying regularity.
  • Greater CD severity, longer disease duration, and older age predicted neck tremor.
  • Female sex was associated with a heightened risk; involvement of other body parts reduced tremor probability.

Conclusions:

  • Machine learning effectively identified predictive clinical features for neck tremor in CD.
  • These findings can improve the accuracy of neck tremor description and patient care pathways.
