Immunoreactive oxytocin (OXT) detected in extracts of human coeliac ganglia and nn. vagi was characterized by high-performance liquid chromatography (HPLC). HPLC/RIA examinations demonstrated that a major part of the immunoreactive material in both investigated areas co-eluted with a reference synthetic OXT, but in the extracts of coeliac ganglia a second immunoreactive peak was also observed.

Complex regional pain syndrome (CRPS) is a chronic pain condition characterized by significant sensory, motor, and autonomic dysfunction, often following trauma or nerve injury. Historically known as causalgia and reflex sympathetic dystrophy, CRPS manifests as severe, disproportionate pain, often accompanied by hyperalgesia, allodynia, trophic changes, and motor impairments. Classified into type I (without nerve injury) and type II (associated with nerve damage), CRPS exhibits a complex pathophysiology involving peripheral and central sensitization, neurogenic inflammation, maladaptive brain plasticity, and potential autoimmune and psychological influences.

Background: Chronic neuropathic pain generally has a poor response to treatment with conventional drugs. Sympathectomy can alleviate neuropathic pain in some patients, suggesting that abnormal sympathetic-somatosensory signaling interactions might underlie some forms of neuropathic pain. The molecular mechanisms underlying sympathetic-somatosensory interactions in neuropathic pain remain obscure.

Management of refractory ventricular fibrillation (VF) in patients with implantable implantable cardioverter defibrillator (ICD) presents a therapeutic challenge. We present a case of pediatric refractory ventricular tachycardia (VT)/Torsade de Pointe managed effectively with bilateral stellate ganglion block (SGB) with a long-acting local anesthetic for 18 days as a bridge to more definitive surgical management.

Functional radiosurgery is a minimally invasive and highly precise approach to managing refractory cancer pain, offering targeted interventions for both nociceptive and neuropathic pain mechanisms. By focusing on key neuroanatomical targets, such as the thalamus, cingulate cortex, pituitary gland, celiac plexus, and dorsal root ganglia, functional radiosurgery provides effective relief for complex pain syndromes that are often unresponsive to conventional therapies. Advances in imaging and treatment delivery have enhanced the safety and efficacy of these techniques, allowing clinicians to tailor interventions to individual patients.

Aim: Tissue clearance is a rapidly evolving technology that allows for the three-dimensional imaging of intact biological tissues. Preexisting tissue-clearing techniques, such as Passive Clarity Technique (PACT) and Clear Unobstructed Brain Imaging Cocktails and Computational Analysis (CUBIC), clear tissues adequately but have distinct disadvantages, such as taking extensive time to clear tissues and degradation of endogenous tissue fluorescence. We developed a new tissue-clearing technique combining PACT and CUBIC protocols to map the neural lineages expressing the transient receptor potential vanilloid type 1 (TRPV1) receptor.
