Lysophosphatidic acid (LPA) is a bioactive lipid that impacts neurological outcomes after neurotrauma by inhibiting neuroregeneration, promoting inflammation, and contributing to behavioral deficits. Blocking LPA signaling with a novel anti-LPA monoclonal antibody (mAb) is neuroprotective after traumatic brain injury (TBI) if given to injured animals whose blood-brain barrier (BBB) has been compromised. It is hypothesized that the anti-LPA mAb could improve chronic pain initiated by TBI. However, poor brain penetration after systemic application of the antibody makes access to the central nervous system (CNS) problematic in situations where the BBB is intact...

The oxytocinergic system is crucial for sociality and well-being and is associated with empathy. It is suggested that the oxytocinergic system exerts context- and person-dependent effects. We examined how sexual sadistic contexts influenced the effects of the oxytocinergic system on empathic-related behaviors and brain activity in healthy adults. Combining genetic neuroimaging, pharmacological techniques and a psychological paradigm of empathy, we recorded EEG neural responses in female OXTR rs53756 G/G and A/A carriers and measured subjective empathic ratings after intranasal administration of oxytocin/placebo in healthy male adults during the perception of painful facial expressions in sadistic/general social contexts...

INTRODUCTION: Ectopic teeth occur in a wide variety of sites, including the maxillary sinus, mandibular condyle, coronoid process, orbital, and nasal cavities. Reported symptoms and signs associated with nasal teeth include facial pain, external nasal deformities, foul-smelling rhinorrhea, recurrent epistaxis, and oronasal fistula. Ectopic teeth occurring bilaterally in the nasal cavity is very very rare. CASE REPORT: A bilateral intranasal ectopic teeth case, which is asymptomatic on the right side and symptomatic on the left side, is presented...

Spreading depression (SD) is a wave of cellular depolarization that travels slowly through susceptible gray matter brain areas. SD is the most likely cause of migraine aura and perhaps migraine pain, and is a well-accepted animal model of migraine. Identification of therapeutics that can prevent SD may have clinical relevance toward migraine treatment. Here we show that insulin-like growth factor-1 (IGF-1) significantly inhibited neocortical SD in vivo after intranasal delivery to rats. A single dose of IGF-1 inhibited SD within an hour, and continued to protect for at least seven days thereafter...

We performed this systematic review and meta-analysis to evaluate the tolerability and efficacy of intranasal sumatriptan, a selective serotonin agonist, compared to placebo or other migraine therapeutics for the treatment of acute migraine attacks. We searched PubMed, SCOPUS, Embase, and Cochrane CENTRAL for relevant randomized controlled trials (RCTs). Data were extracted from eligible studies and pooled as risk ratios (RR), using RevMan software. We performed subgroup and meta-regression analyses for different doses and treatment endpoints...

One of the side-effects of ketamine abuse is genito-urinary damage. This report describes a case of a former ketamine user who presented with urinary symptoms associated with ketamine years after stopping consumption. This was a 26-year-old male with a history of ketamine abuse. He started treatment for alcohol dependence at age 19. He smoked marijuana daily and denied any other drug use. During the follow-up, urinary symptoms were evidenced (dysuria, frequency, urgency, incontinence, nocturia, hematuria, and suprapubic pain)...

REVIEW
Hida Nierenburg, Morgane Swift Morris
PURPOSE OF REVIEW: External nasal neuralgia is a rare syndrome of atypical facial pain for which there is limited reports in the scientific literature. We aim to review diagnosis and provide an update on treatments for this rare condition. RECENT FINDINGS: Etiology has been documented as post-traumatic due to direct trauma to the nose area and in few case reports, idiopathic. Sensory innervation of the nose arises from the ophthalmic and maxillary divisions of the trigeminal nerve...

BACKGROUND: Fast relief of migraine pain, associated symptoms, and migraine-related disability are priorities in the acute treatment of migraine. Efforts to improve the pharmacokinetic profiles of acute migraine treatments with the aim of providing faster relief include the development of non-oral routes of administration. AVP-825 (ONZETRA(®) Xsail(®) ) is a delivery system containing 22 mg sumatriptan powder that uses a patient's own breath to deliver medication intranasally, targeting the upper posterior nasal cavity beyond the narrow nasal valve, an area lined with vascular mucosa conducive to rapid drug absorption into the systemic circulation...

Studies on the development of drug delivery systems have increased because these systems have particular characteristics that allow them to improve therapeutics. Among these, lipid nanoparticles (solid lipid nanoparticles, SLNs; and nanostructured lipid carriers, NLCs) have demonstrated suitability for drug targeting. The nasal administration of drug-loaded lipid nanoparticles showed effectiveness in treating central nervous system (CNS) disorders, particularly neurodegenerative diseases, because the nasal route (also called intranasal route) allows direct nose-to-brain drug delivery by means of lipid nanoparticles...

Heart rate variability (HRV) refers to variation in the interval between successive heart beats. Low HRV is an indicator of potential autonomic nervous system dysfunction. People with chronic pain often display autonomic dysregulation, especially in the parasympathetic nervous system. The hormone oxytocin has been shown to increase HRV in non-clinical samples, but its potential impact on HRV in persons with chronic pain is unknown. This study investigated the impact of intranasal oxytocin on HRV in persons with chronic neck and shoulder pain...

Lisgelia Santana, Katherine Mills
OBJECTIVES: This study evaluated the effect of intranasal dexmedetomidine on emergence delirium (ED) in pediatric patients who underwent ear tube surgeries. Due to the brief nature of the surgery and low levels of pain experienced, an IV is rarely needed, limiting the medications available to anesthesiologists to manage postoperative delirium that may arise during recovery from inhalational anesthesia. Intravenous dexmedetomidine is an alpha-2 agonist anesthetic that is used in pediatric patients for the management of ED in various surgical procedures...

Patients perceive the pulling of a nasal splints as the most feared and stressful part of nasal surgery. Even the incisions made for alar base surgery can partly or entirely dehisce. So, we have been using modified Doyle silicone splints. We compared the modified Doyle silicone splints with conventional Doyle silicone splint. Included in the study were 64 patients undergoing alar base surgery together with open septorhinoplasty. Group 1 (n = 32) patients received a conventional Doyle intranasal silicone splint and group 2 (n = 32) received modified splint that we call a hemi-split Doyle splint...

We were very interested to read Scheier et al's brief report on the use of intranasal ketamine in their pediatric emergency department, specifically for pain and anxiety in children who had resisted venipuncture or intravenous placement (1). Intravenous access can be difficult for pre-hospital medical teams that are not specialised in paediatric care, namely when children complain of pain from, for example suspected fractures and burns.

INTRODUCTION: Patients with trigeminal neuralgia (TN) are often refractory to recommended first-line agents. Due to the absence of a systematic review, we undertook a network meta-analysis to assess various interventions that can be used to manage refractory TN. METHODS: Electronic databases were searched using appropriate strategies to identify randomized controlled clinical trials in patients with refractory TN, evaluating the proportion of patients with a minimum of 50% reduction in pain or a minimum of 2 cm reduction in score in an appropriate pain scale or complete pain relief by subjective pain scales...

BACKGROUND: Emergence delirium is defined as a cognitive disturbance during emergence from general anesthesia resulting in hallucinations, delusions and confusion manifested by agitation, restlessness, involuntary physical movement and extreme flailing in bed. Postoperative emergence delirium develops in 12% to 18% of all children undergoing general anesthesia for surgery. This post-anesthetic phenomenon changes cognitive and psychomotor behavior, and puts pediatric patients and health care personnel at risk of injury...

INTRODUCTION: Pediatric sickle cell disease, highly prevalent in sub-Saharan Africa, carries great morbidity and mortality risk. Limited resources and monitoring make management of acute vaso-occlusive crises challenging. This study aims to evaluate the efficacy and safety of subdissociative intranasal ketamine as a cheap, readily available and easily administered adjunct to standard pain therapy. We hypothesise that subdissociative, intranasal ketamine may significantly augment current approaches to pain management in resource-limited settings in a safe and cost-effective manner...

According to Centers for Disease Control and Prevention, each year, an estimated 1.7 million Americans sustain a traumatic brain injury (TBI), which frequently leads to chronic craniofacial pain. In this study we examine a gene therapy approach to the treatment of post-TBI craniofacial neuropathic pain using nasal application of a herpes simplex virus (HSV)-based vector expressing human proenkephalin (SHPE) to target the trigeminal ganglia. Mild TBI was induced in rats by the use of a modified fluid percussion model...
