Analgesia and Pain Management01:25

Analgesia and Pain Management

2.8K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Nociception01:44

Nociception

34.3K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

646
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...

Pain01:20

Pain

1.8K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

7.3K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

871
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...

Area of Science:

  • Neurology
  • Pain Medicine
  • Neuroscience

Background:

  • Chronic pain frequently complicates central nervous system injuries, including stroke.
  • Pain types include musculoskeletal, overuse, and direct neuropathic pain from CNS injury.
  • Differentiating central neuropathic pain from other pain types or spasticity is challenging due to impaired sensory discrimination.

Purpose of the Study:

  • To identify unique clinical features distinguishing central neuropathic pain.
  • To review common central pain syndromes: central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain.
  • To discuss recent advances in understanding pathogenesis and treatment of central neuropathic pain.

Main Methods:

  • Literature review focusing on clinical features, pathogenesis, and treatments.
  • Detailed review of central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain.
  • Synthesis of current knowledge on pharmacological, surgical, and neuromodulatory interventions.

Main Results:

  • Central neuropathic pain can manifest months to years after initial injury, complicating diagnosis.
  • Specific clinical features aid in distinguishing central neuropathic pain from other pain types.
  • Understanding of pathogenesis is advancing, informing treatment strategies.

Conclusions:

  • Central neuropathic pain is a distinct and challenging clinical entity requiring specific diagnostic approaches.
  • Effective management involves a multidisciplinary approach, including pharmacological, surgical, and neuromodulatory options.
  • Further research into pathogenesis and treatment is crucial for improving patient outcomes.
