Anita Gupta, Lucas First, Celeste A Swain
Peripheral nerve hyperexcitability (PNH) syndromes are a rare set of neuromuscular disorders that include cramp-fasciculation syndrome (CFS) and Isaacs syndrome (IS). Successful treatment of these diseases has been achieved with antiepileptic medications; however, chronic pain symptoms can persist. We provide a case report of a 25-year-old female who has suffered from painful severe muscle spasms and fasciculations since childhood. With CFS as our working diagnosis, a treatment regimen using interventional pain techniques, including sympathetic chain blocks, ketamine infusions, and trigger point injections, resulted in a significant decrease in the patient's chronic pain symptoms...

OBJECTIVE: A few studies report comparable analgesic efficacy between low-dose ketamine and opioids such as morphine or fentanyl; however, limited research has explored the safety and effectiveness of intravenous low-dose ketamine as a primary analgesic in a civilian prehospital setting. The objective of this study is to compare pain control between low-dose ketamine and fentanyl when administered intravenously (IV) for the indication of severe pain. METHODS: This was a retrospective, observational review of prehospital adult patients (≥18 years) who presented with severe pain (numeric rating scale, 7-10) and were treated solely with either low-dose ketamine IV or fentanyl IV between January 1, 2014 and December 31, 2016...

Background: Evidence is overwhelming for sex differences in pain, with women representing the majority of the chronic pain patient population. There is a need to explore novel avenues to elucidate this sex bias in the development of chronic inflammatory pain conditions. Complex regional pain syndrome (CRPS) is a chronic neuropathic pain disorder, and the incidence of CRPS is greater in women than in men by ~4:1. Since neurogenic inflammation is a key feature of CRPS, dysregulation of inflammatory responses can be a factor in predisposing women to chronic pain...

BACKGROUND: Postoperative pain is a frequent cause for delayed discharge following outpatient procedures, including anorectal surgery. Both central and peripheral pain receptor sensitization are thought to contribute to postoperative pain. Blocking these receptors and preempting sensitization prevents hyperalgesia leading to lower pain medication requirements. Studies in the orthopedic, urologic, and gynecologic literature support this practice, but the use of preemptive analgesia in anorectal surgery is understudied...

BACKGROUND: The pharmacokinetics of infused drugs have been modeled without regard for recirculatory or mixing kinetics. We used a unique ketamine dataset with simultaneous arterial and venous blood sampling, during and after separate S(+) and R(-) ketamine infusions, to develop a simplified recirculatory model of arterial and venous plasma drug concentrations. METHODS: S(+) or R(-) ketamine was infused over 30 min on two occasions to 10 healthy male volunteers...

Organic or secondary psychosis can be seen in diverse conditions such as toxic/metabolic disorders, neurodegenerative disease, and stroke. Poststroke psychosis is a rare phenomenon, but its study has significantly contributed to the understanding of delusion formation. The evidence from case studies of patients with focal strokes shows that delusions develop following unilateral damage of the right hemisphere. The majority of patients with right hemisphere stroke do not develop delusions however, and advanced neuroimaging analysis has elucidated why this symptom develops in only a small proportion...

Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is one of the most robust neurobiological findings in the pathophysiology of major depressive disorder (MDD) over the last 40 years. The persistent increase in glucocorticoids levels induces morphological and anatomical changes in the brain, especially in the hippocampus. Ketamine represents a major advance for the treatment of MDD, however the psychotomimetic effects of this compound limit its widespread use. Agmatine is a neuromodulator that has been shown to be a putative novel and well-tolerated antidepressant/augmenter drug...

BACKGROUND: Currently, there is no gold standard for monitored anaesthesia care during oocyte retrieval. OBJECTIVE: In our institution, the standard is a conscious sedation technique using a target-controlled infusion (TCI) of remifentanil, titrated to maintain a visual analogue pain score less than 30 mm. This protocol is well accepted by patients but is associated with frequent episodes of respiratory depression. The main objective of this study was to evaluate whether the addition of a continuous intravenous infusion of ketamine could reduce these episodes...

Entomotoxicology is a branch of forensic entomology that studies the detection of drugs or other toxic substances from insects developing on the decomposing tissues of a human corpse or animal carcass. Entomotoxicology also investigates the effects of these substances on insect development, survival and morphology to provide an estimation of the minimum time since death. Ketamine is a medication mainly used for starting and maintaining anesthesia. In recent years ketamine has also been used as a recreational drug, and occasionally as a sedating drug to facilitate sexual assault...

Ketamine is considered a dissociative anesthetic medication, and it is a commonly administered by a parenteral route. It works mainly by blocking the N-methyl-D-aspartate (NMDA) receptor. It inhibits the voltage-gated Na_ and K_ channels and serotonin and dopamine re-uptake; also, it affects specific receptors, such as α-amino-3-hydroxy-5-methyl-4- isoxazolepropionic acid (AMPA), kainate and aminobutyric acid A receptors. Ketamine appears to have particular mechanisms that are potentially involved during analgesic induction, including enhancing of descending inhibition and anti-inflammatory effects...

Anxiety disorders and posttraumatic stress disorder (PTSD) share a common feature of pathological avoidance behavior. The Wistar Kyoto (WKY) rat has been used as a model of anxiety vulnerability, expressing a behaviorally inhibited temperament, acquiring avoidance behavior more rapidly and displaying extinction-resistant avoidance compared to Sprague Dawley (SD) rats. Subanesthetic levels of ketamine have gained attention as a rapid antidepressant in treatment-resistant depression. While traditional antidepressants are commonly used to treat anxiety disorders and PTSD, the therapeutic utility of ketamine for these disorders is much less understood...
