Alkindi Sprinkle for Pediatric Patients With Primary Adrenocortical Insufficiency: A Narrative Review.

Adrenocortical insufficiency, also known as adrenal insufficiency (AI), is an endocrine disorder characterized by inadequate production of adrenal hormones, including glucocorticoids and mineralocorticoids (MCs). The condition can be categorized as primary, secondary, or tertiary AI, depending on the location of the defect. Classical symptoms of AI include weakness, fatigue, abdominal pain, tachycardia, hypotension, electrolyte imbalances, and hyperpigmentation. In children, the most common cause of AI is classical congenital adrenal hyperplasia, which results from a deficiency in the 21-hydroxylase enzyme. The 21-hydroxylase enzyme produces all steroids, such as cortisol and aldosterone. AI management primarily involves hormone replacement therapy, typically with oral hydrocortisone and MC supplementation. However, the administration of hydrocortisone to pediatric patients presents challenges related to the lack of available dose-appropriate formulations. Historically, crushed or split adult tablets were used for the pediatric treatment of AI, although this poses an increased risk of under- or overtreatment. Inadequate dosing in the pediatric population can adversely affect growth, development, and metabolic health. Alkindi Sprinkle is a pediatric-specific hydrocortisone oral granule preparation that manages cortisol levels to help facilitate accurate therapeutic dosing. Alkindi offers several advantages, including accurate dosing, taste masking, and ease of administration. The present investigation describes AI, the management of AI, and the treatment of pediatric AI using Alkindi Sprinkle, including clinical efficacy.

Non-steroidal Anti-inflammatory Drug (NSAID)-, Potassium Supplement-, Bisphosphonate-, and Doxycycline-Mediated Peptic Ulcer Effects: A Narrative Review.

Peptic ulcers are a common condition that arises from an imbalance between acid production and gastroduodenal protective factors. Various drugs, including non-steroidal anti-inflammatory drugs (NSAIDs), potassium supplements, bisphosphonates, and doxycycline, can increase the development of peptic ulcers. NSAIDs are one of the most common medications prescribed for pain relief, and they also inhibit the formation of cyclooxygenase-1 (COX-1). COX-1 helps in the production of mucus that lines the stomach, so by inhibiting COX-1, NSAIDs reduce the mucus produced by the stomach and increase the likelihood of gastric ulcer formation. Additionally, NSAIDs are acidic, and increasing the amount of any acid in the stomach can result in promoting ulcer development. Potassium supplements are used to reduce the effects of hypertension, decrease the development of kidney stones, and treat hypokalemia. The various types of transporters and channels used to move potassium across cell membranes increase hydrogen being pumped, increasing gastric acid production and ulcer formation. Bisphosphonates are used to treat a variety of skeletal disorders that require inhibition of osteoclast activity. Nitric oxide (NO) has been shown to have a therapeutic effect on gastric ulcers, and some bisphosphonates have been shown to decrease the production of nitric oxide, resulting in increased damage to the gastric mucosa. Finally, doxycycline is a broad-spectrum tetracycline antibiotic that is typically used to treat anthrax poisoning, skin lesions, and sexually transmitted diseases. A harmful adverse effect of doxycycline is the formation of peptic and gastric ulcers related to the drug being highly acidic once it has dissolved.

Spina Bifida Prevention: A Narrative Review of Folic Acid Supplements for Childbearing Age Women.

Neural tube defects (NTDs) are malformations that occur during embryonic development, and they account for most central nervous system birth anomalies. Genetic and environmental factors have been shown to play a role in the etiology of NTDs. The different types of NTDs are classified according to anatomic location and severity of the defect, with most of the neural axis anomalies occurring in the caudal spinal or cranial areas. Spina bifida is a type of NTD that is characterized by an opening in the vertebral arch, and the level of severity is determined by the extent to which the neural tissue protrudes through the opened arch(es). Prevention of NTDs by administration of folic acid has been studied and described in the literature, yet there are approximately 300,000 cases of NTDs that occur annually, with 88,000 deaths occurring per year worldwide. A daily intake of at least 400 µg of folic acid is recommended especially for women of childbearing age. To provide the benefits of folic acid, prenatal vitamins are recommended in pregnancy, and many countries have been fortifying foods such as cereal grain products with folic acid; however, not all countries have instituted folic acid fortification programs. The present investigation includes a description of the pharmacology of folic acid, neural tube formation, defects such as spina bifida, and the relevance of folic acid to developing spina bifida. Women's knowledge and awareness of folic acid regarding its importance in the prevention of spina bifida is a major factor in reducing incidence worldwide.

Mechanisms and Treatment Options for Hyperthyroid-Induced Osteoporosis: A Narrative Review.

Normal thyroid hormone levels are crucial for the homeostasis of many metabolic cycles and processes throughout the human body. Thyroid dysfunction, such as thyrotoxicosis, can result from many different etiologies, including Graves' disease (GD), toxic multinodular goiter (MNG), and toxic adenoma. These hyperthyroid disease states can cause devastating complications and disease, including the disruption of the bone remodeling cycle and skeletal development, which can result in osteoporosis. Osteoporosis is characterized by a decrease in bone mineral density and a propensity for fragility fractures. In addition to patients with overt hyperthyroidism, studies have provided evidence of other high-risk patient demographics, such as individuals with subclinical hyperthyroidism and postmenopausal women, who may be at an increased risk for the development of secondary osteoporosis. The treatment of patients with hyperthyroid-induced osteoporosis often requires a multifaceted management plan that may be unique to each patient's situation. Antithyroid therapy is often the first step in treating this disease and may include thioamide medications. Radioactive iodine-131 therapy (RAI) and the surgical removal of the thyroid gland may also be reasonable approaches for restoring normal thyroid function. Following thyrotoxicosis mitigation, antiresorptive drugs such as bisphosphonates, calcitonin, and selective estrogen receptor modulators (SERMs) may be used to counteract decreased bone mineral density (BMD). Additionally, the implementation of vitamin D, calcium supplements, and weight-bearing exercise may also reduce bone loss. While the effects of thyroid stimulating hormone (TSH) and triiodothyronine (T3) on bone remodeling have been studied in the past, more research is needed to identify unknown mechanisms and develop future improved treatments for this condition.

Oral Therapeutics Post Menopausal Osteoporosis.

Osteoporosis affects a significant number of postmenopausal women in the United States. Screening is performed using clinical assessments and bone mineral density scans via dual x-ray absorptiometry. Oral therapy is indicated to prevent pathologic fractures in those deemed at increased risk following screening. Bisphosphonates including alendronate, ibandronate, and risedronate are currently first-line oral therapeutics in fracture prevention following the diagnosis of osteoporosis. Hormonal therapies include estrogen-containing therapies, selective estrogen receptor modulators, and other compounds that mimic the effects of estrogen such as tibolone. Lifestyle modifications such as supplementation and physical activity may also contribute to the prevention of osteoporosis and are used as adjuncts to therapy following diagnosis. These therapeutics are limited primarily by their adverse effects. Treatment regimens should be tailored based on significant risk factors demonstrated by patients, adverse effects, and clinical response to treatment. The most severe risk factors relevant to pharmacological selection involve hormone replacement therapies, where concern for venous thrombosis, coronary artery disease, breast, and uterine cancer exist. Bisphosphonates are most commonly associated with gastrointestinal discomfort which may be mitigated with proper administration. Although adverse effects exist, these medications have proven to be efficacious in the prevention of vertebral and non-vertebral fractures in post-menopausal women. Fracture risk should be weighed against the risk of adverse events associated with each of the regimens, with clinical judgment dictating the treatment approach centered around patient goals and experiences.

Medial Branch Blocks and the Effectiveness of Radiofrequency Neurotomy in Managing Chronic Thoracic Pain: A Systematic Review and Meta-Analysis.

BACKGROUND: Extensive research into potential sources of thoracic pain with or without referred pain into the chest wall has demonstrated that thoracic facet joints can be a potential source of pain confirmed by precise, diagnostic blocks.The objective of this systematic review and meta-analysis is to evaluate the effectiveness of medial branch blocks and radiofrequency neurotomy as a therapeutic thoracic facet joint intervention. METHODS: Systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies of medial branch blocks and the radiofrequency neurotomy in managing thoracic pain utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was performed. A comprehensive literature search of multiple databases of RCTs and observational studies of medial branch blocks and radiofrequency neurotomy in managing chronic thoracic pain were identified from 1996 to December 2022 with inclusion of manual searches of the bibliography of known review articles and multiple databases. Methodologic quality and risk of bias assessment was also conducted. Evidence was synthesized utilizing principles of quality assessment and best evidence synthesis, with conventional and single meta-analysis. The primary outcome measure of success was 3 months of pain reduction for medial branch blocks and 6 months for radiofrequency thermoneurolysis for a single treatment. Short-term success was defined as up to 6 months and long-term was more than 6 months. RESULTS: This literature search yielded 11 studies meeting the inclusion criteria, of which 3 were RCTs and 8 were observational studies. Of the 3 RCTs, 2 of them assessed medial branch blocks and one trial assessed radiofrequency for thoracic pain. The evidence for managing thoracic pain with qualitative analysis and single-arm meta-analysis and GRADE system of appraisal, with the inclusion of 2 RCTs and 3 observational studies for medial branch blocks was Level II. For radiofrequency neurotomy, with the inclusion of one RCT of 20 patients in the treatment group and 5 observational studies, the evidence was Level III in managing thoracic pain. LIMITATIONS: There was a paucity of literature with RCTs and real-world pragmatic controlled trials. Even observational studies had small sample sizes providing inadequate clinically applicable results. In addition, there was heterogeneity of the available studies in terms of their inclusion and exclusion criteria, defining their endpoints and the effectiveness of the procedures. CONCLUSION: This systematic review and meta-analysis show Level II evidence of medial branch blocks and Level III evidence for radiofrequency neurotomy on a long-term basis in managing chronic thoracic pain. KEY WORDS: Chronic spinal pain, thoracic facet or zygapophysial joint pain, facet joint nerve blocks, medial branch blocks, controlled comparative local anesthetic blocks, diagnostic accuracy, radiofrequency neurotomy.

Low-Level Laser Therapy for Acute Pain: A Comprehensive Review.

PURPOSE OF REVIEW: An analysis of data conducted in 2015 by the National Health Interview Survey (NHIS) found that an estimated 25.3 million adults (11.2%) have experienced pain every day for the preceding 3 months, and nearly 40 million adults (17.6%) have experienced a severe level of pain. RECENT FINDINGS: Multiple reviews have analyzed the current management of acute pain; however, much of the current literature only focuses on pharmacological methods of analgesia, such as opiates, ketamine, or non-steroidal anti-inflammatory drugs (NSAIDs). Publications that discuss non-pharmacological options often criticize the limitations of available research for these therapies, making further exploration of this type of treatment necessary. The present investigation aims to summarize current knowledge on the use of low-level laser therapy (LLLT), a cold laser non-pharmacological approach, in managing acute pain and to discuss important clinical findings and considerations when it comes to utilizing this treatment option in patients.

Chronic Administration of Melatonin: Physiological and Clinical Considerations.

BACKGROUND: Exogenous melatonin is commonly used to treat insomnia, other sleep problems, and numerous medical illnesses, including Alzheimer's disease, autism spectrum disorder, and mild cognitive impairment in adults and children. There is evolving information regarding issues with the use of chronic melatonin. METHODS: The present investigation was a narrative review. RESULTS: Melatonin usage has risen dramatically in recent years. Many countries only allow melatonin prescriptions. In the United States (U.S.), it is classified as a dietary supplement accessible over the counter and can be derived from animals, microorganisms, or, most commonly, made synthetically. No regulatory agency oversees its manufacturing or sale in the U.S. melatonin concentration of marketed preparations varies widely between product labels and manufacturers. Melatonin's ability to induce sleep is detectable. However, it is modest for most people. Sleep length appears to be less important in sustained-release preparations. The optimal dosage is unknown, and routinely used amounts vary substantially. Melatonin's short-term negative effects are minimal, resolve at medicine cessation, and do not usually prevent usage overall. Much research on long-term melatonin administration has found no difference between exogenous melatonin and placebo in terms of long-term negative effects. CONCLUSION: Melatonin at low to moderate dosages (approximately 5-6 mg daily or less) appears safe. Long-term usage appears to benefit certain patient populations, such as those with autism spectrum disorder. Studies investigating potential benefits in reducing cognitive decline and increased longevity are ongoing. However, it is widely agreed that the long-term effects of taking exogenous melatonin have been insufficiently studied and warrant additional investigation.

Koro Syndrome: Epidemiology, Psychiatric and Physical Risk Factors, Clinical Presentation, Diagnosis, and Treatment Options.

Koro syndrome is a multi-tiered disease presenting as an overwhelming belief that one's sex organs are shrinking into their body. Moderate to severe anxiety attacks are associated with the condition, along with a fear of imminent death. Koro is often culturally related and is most seen as an epidemic form in East and Southeast Asia, although it can present anywhere worldwide in its sporadic form. The condition typically affects young males who believe in sex-related myths, and many individuals can co-present with anxiety, depression, or even psychosis. Although most presentations of Koro are self-limiting, the condition is harmful for one's self-esteem and quality of life, and some individuals may go through extreme, physically injurious measures to prevent genital retraction. Treatments include the use of psychotherapy that has a sex education component, especially if the patient believes in culturally rooted myths. In sporadic Koro, it is believed that if the primary psychiatric disorder is treated with anxiolytics, antidepressants, sedatives, or psychotics, the secondary Koro-like symptoms will also fade. Additional investigation on the prevalence, pathogenesis, factors that correlate with treatment efficacy are needed to fully understand Koro syndrome.

Vitamin A-Mediated Birth Defects: A Narrative Review.

Vitamin A deficiency (VAD) or excess in expectant mothers can result in fetal abnormalities such as night blindness, bone anomalies, or epithelial cell problems. In contrast, excessive vitamin A in pregnancy can precipitate fetal central nervous system deformities. During pregnancy, a pregnant woman should monitor her vitamin A intake ensuring she gets the recommended dosage, but also ensuring she doesn't exceed the recommended dosage, because either one can result in teratogenicity in the fetus. The widespread and unregulated use of multivitamins and supplements makes consuming doses greater than the recommended quantity more common in developed countries. While vitamin A excess is more common in developed countries, deficiency is most prevalent in developing countries. With proper maintenance, regulation, and education about VAD and excess, a pregnant mother can diminish potential harm to her fetus and potential teratogenic risks.

A comprehensive review of intraarticular knee injection therapy, geniculate injections, and peripheral nerve stimulation for knee pain in clinical practice.

The knee is the most common joint in adults associated with morbidity. Many pathologies are associated with knee damage, such as gout or rheumathoid arthritis, but the primary condition is osteoarthritis (OA). Not only can osteoarthritis cause significant pain, but it also can result in signficant disability as well. Treatment for this condition varies, starting off with oral analgesics and physical therapy to surgical total knee replacmenet. In the gamut of this various treatments, a conservative approach has included intra articular steroid injections. With time, researchers and clinicians determined that other components injected to the knee may additionally provide relief of this condition. In this investigation, we describe different types of knee injections such as platelet-rich plasma (PRP), hyaluronic acid, stem cells, and prolotherapy. Additionally, we describe the role of geniculate knee injections, radiofrequency, and periopheral nerve stimulation. These treatments should be considered for patients with knee pain refractory to conservative therapies.

Viloxazine, a Non-stimulant Norepinephrine Reuptake Inhibitor, for the Treatment of Attention Deficit Hyperactivity Disorder: A 3 Year Update.

Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder in childhood. Current treatment options for ADHD include pharmacological treatment (stimulants, non-stimulants, anti-depressants, anti-psychotics), psychological treatment (behavioral therapy with or without parent training, cognitive training, neurofeedback), and complementary and alternative therapies (vitamin supplementation, exercise). Central nervous system (CNS) stimulants are the primary pharmacological therapy used in treatment; however, these stimulant drugs carry a high potential for abuse and severe psychological/physical dependence. Viloxazine, a non-stimulant medication without evidence of drug dependence, is a selective norepinephrine reuptake inhibitor that has historically been prescribed as an anti-depressant medication. The extended-release (ER) form was approved by the US Food and Drug Administration (FDA) in April 2021 for the treatment of ADHD in pediatric patients aged 6-17 years. Phase 2 and 3 randomized control trials have demonstrated significant efficacy of viloxazine in improving ADHD symptoms versus placebo. Related to its long-standing use as an antidepressant, the safety profile and pharmacokinetics of viloxazine are well understood. Viloxazine appears to be a suitable alternative to current standard-of-care pharmacotherapy for ADHD, but the further investigation remains to be done in comparing its efficacy to that of current treatments.

A Comprehensive Update of Prolotherapy in the Management of Osteoarthritis of the Knee.

This is a comprehensive review of the literature focusing on the use of prolotherapy in the treatment of osteoarthritis of the knee. It covers the background, efficacy, and advantages of prolotherapy in the management of osteoarthritis symptoms and then covers the existing evidence of the use of prolotherapy for this purpose. Current treatments for osteoarthritis of the knee are numerous, yet patients continue to endorse chronic pain and poor quality of life. Prolotherapy is a treatment that has been inadequately studied with poor sample sizes and lack of standardization between trials. However, in recent years the literature on prolotherapy in the treatment of knee osteoarthritis has grown. Although there is still a lack of homogeneity, trials have shown that dextrose prolotherapy, autologous conditioned serum, hyaluronic injections, and normal saline administered either intra- or peri-articularly are comparable in reducing pain scores to other primary treatment options. The mechanism of action for prolotherapy is still unclear, but researchers have found that prolotherapy plays some role in cartilage growth or chondrogenesis and has been shown to have improved radiographic outcomes. Prolotherapy appears to be a safe treatment alternative that has been shown to improve stiffness, pain, function, and quality of life in osteoarthritis of the knee. Knee osteoarthritis is remarkably prevalent in the United States and is one of the most common causes of disability in the elderly population. Although there are many treatment options, patients continue to live with chronic pain which can incur high costs for patients. A safe, long-term, and effective solution has not yet been identified. Prolotherapy has been shown to be a safe option for improving pain, function, and quality of life as effectively as other treatment options.

An Update on Posterior Tarsal Tunnel Syndrome.

Posterior tarsal tunnel syndrome (PTTS) is an entrapment neuropathy due to compression of the tibial nerve or one of its terminal branches within the tarsal tunnel in the medial ankle. The tarsal tunnel is formed by the flexor retinaculum, while the floor is composed of the distal tibia, talus, and calcaneal bones. The tarsal tunnel contains a number of significant structures, including the tendons of 3 muscles as well as the posterior tibial artery, vein, and nerve. Focal compressive neuropathy of PTTS can originate from anything that physically restricts the volume of the tarsal tunnel. The variety of etiologies includes distinct movements of the foot, trauma, vascular disorders, soft tissue inflammation, diabetes mellitus, compression lesions, bony lesions, masses, lower extremity edema, and postoperative injury. Generally, compression of the posterior tibial nerve results in clinical findings consisting of numbness, burning, and painful paresthesia in the heel, medial ankle, and plantar surface of the foot. Diagnosis of PTTS can be made with the presence of a positive Tinel sign in combination with the physical symptoms of pain and numbness along the plantar and medial surfaces of the foot. Initially, patients are treated conservatively unless there are signs of muscle atrophy or motor nerve involvement. Conservative treatment includes activity modification, heat, cryotherapy, non-steroidal anti-inflammatory drugs, corticosteroid injections, opioids, GABA analog medications, tricyclic antidepressants, vitamin B-complex supplements, physical therapy, and custom orthotics. If PTTS is recalcitrant to conservative treatment, standard open surgical decompression of the flexor retinaculum is indicated. In recent years, a number of alternative minimally invasive treatment options have been investigated, but these studies have small sample sizes or were conducted on cadaveric models.

Occipital Nerve Stimulation: An Alternative Treatment of Chronic Migraine.

PURPOSE OF REVIEW: This paper will examine the efficacy and safety of occipital nerve stimulation as a non-pharmacological alternative treatment for migraine. RECENT FINDINGS: Migraine is characterized as a primary headache disorder with possible premonitory and aura phases, both of which vary greatly in symptomatology. The most common treatments for chronic migraine are pharmacological and are aimed at both acute relief (e.g., nonsteroidal anti-inflammatory drugs, triptans, and ergots) and prophylaxis (e.g., propranolol, valproic acid, and topiramate). For patients with medically refractory migraine, acute relief medication overuse can increase the risk of developing more severe and more frequent migraine attacks. Occipital nerve stimulation is a non-pharmacological alternative treatment for chronic migraine, which could eliminate the risk of adverse effects from acute relief medication overuse. Neurostimulation is thought to prevent pain by blocking signal transduction from small nociceptive fibers with non-painful signaling in larger adjacent fibers. Existing data from clinical trials support the overall safety and efficacy of occipital nerve stimulation for the treatment of chronic migraine. However, few large controlled, double-blinded studies have been conducted, due to both practical and ethical concerns. Currently, occipital nerve stimulation is available as an off-label use of neurostimulation for pain prevention but is not approved by the FDA specifically for the treatment of chronic migraine.

A Comprehensive Review of the Use of Alpha 2 Agonists in Spinal Anesthetics.

BACKGROUND: Spinal Anesthesia was the first regional anesthetic technique to be performed. It was performed by Dr. August Bier, known for the Bier block, and his colleagues on August 16, 1898. Dr. Bier opted for, what he referred to at the time as "cocainization of the spinal cord" by introducing 15 mg of cocaine intrathecally prior to the operation. The surgery was largely uneventful and painless. The patient only experienced some vomiting and a headache postoperatively. Dr. Bier's use of neuraxial anesthesia aimed to directly inject local anesthetics in and around the central nervous system (CNS) for more direct control of pain and anesthesia. Local anesthetics were an important discovery in anesthesiology. However, since the advent of local anesthetics and spinal anesthesia as an alternative technique to general anesthesia, much has been learned about both the benefits and adverse effects of local anesthetics. It was quickly learned that use of local anesthetics would be limited by their potential for life-threatening toxic effects. For this reason, there was a push towards development of novel local anesthetics that had a larger therapeutic window with less likelihood of serious side effects. In addition to developing newer local anesthetics, the idea of adding adjuvants provided an opportunity to potentially limit the life-threatening events. These adjuvants would include medications such as epinephrine and alpha-2 agonists, such as clonidine and dexmedetomidine. Other adjuvants include opioids, glucocorticoids, and mineralocorticoids. OBJECTIVES: In this review, we will delve further into the indications, contraindications, uses, mechanisms, and future of spinal anesthesia and its adjuvants. STUDY DESIGN: A literature review of recent publications in the field of alpha 2 agonists used in spinal anesthetics was carried out from 2015 to present day. Consensus opinions were formulated in various areas. SETTING: This literature review was carried out at various medical universities throughout the nation and Europe. LIMITATIONS: As research has only just begun in this field data is limited at this time. CONCLUSIONS: The use of spinal anesthesia provides a reliable dermatome blockade to facilitate many different surgical procedures. The combination of local anesthetics with opioid medications within the subarachnoid space has been the standard of care. Adjuvant medications like alpha 2 agonists may play a significant role in prolonging spinal blockade as well as limiting cardiovascular complications such as hypotension and bradycardia. The use of alpha 2 agonists instead of opioid medications intrathecally decreases pruritus and delayed respiratory depression. Animal models have demonstrated the synergistic effects of utilizing alpha 2 agonists with opioids in the subarachnoid space. The addition of clonidine to fentanyl and local anesthetic demonstrated a shorter time to neural blockade, but no significant change in duration of the spinal. Interestingly alpha 2 agonists with local anesthetics showed increase block duration compared to opioid with local anesthetics. Further human trials need to be undertaken to analyze the effectiveness of alpha 2 agonists in the intrathecal space, but preliminary data does indicate it is an exemplary alternative to opioids.

Oxytocin, a Novel Treatment for Methamphetamine Use Disorder.

The treatment of substance abuse with oxytocin is a novel approach to a challenging public health issue that continues to contribute to a growing economic cost for societies worldwide. Methamphetamine addiction is one of the leading causes of mortality worldwide, and despite advances in understanding the neurobiology of methamphetamine addiction, treatment options are limited. There are no medications that the Food and Drug Administration currently approves for stimulant use disorder. Off-label use of therapies for stimulant misuse include antidepressants, anxiolytics, and milder stimulants as replacement agents. Due to the shortcomings of these attempts to treat a complicated psychiatric disorder, recent attention to oxytocin therapy (OT) has gained momentum in clinical studies as a possible therapy in the context of social stress, social anxiety, social cognition, and psychosis. Oxytocin produces enhanced connectivity between cortical regions. The results from studies in rodents with OT suggest that central neuromodulation of oxytocin may be beneficial across transition states of stimulant dependence and may alleviate intense withdrawal symptoms. Studies of oxytocin in the context of other drugs of abuse, including cocaine, cannabis, and alcohol, also support the potential of oxytocin to treat stimulant use disorder, methamphetamine type. Methamphetamine abuse continues to be a significant cause of distress and dysfunction throughout the world. The effects of oxytocin on methamphetamine use outlined in this review should act as a catalyst for further investigation into the efficacy of treating stimulant use disorder, methamphetamine type with oxytocin in humans. More human-based research should initiate studies involving the long-term efficacy, side effects, and patient selection.

Dorsal Column Stimulation and Cannabinoids in the Treatment of Chronic Nociceptive and Neuropathic Pain: a Review of the Clinical and Pre-clinical Data.

PURPOSE OF REVIEW: The main objective of this review is to appraise the literature on the role of spinal cord stimulation (SCS), cannabinoid therapy, as well as SCS and cannabinoid combination therapy for the management of chronic neuropathic and nociceptive pain. Current research suggests that SCS reduces pain and increases functional status in carefully selected patients with minimal side effects. RECENT FINDINGS: As cannabinoid-based medications become a topic of increasing interest in pain management, data remains limited regarding the clinical efficacy of cannabinoids for pain relief. Furthermore, from a mechanistic perspective, although various pain treatment modalities utilize overlapping pain-signaling pathways, clarifying whether cannabinoids work synergistically with SCS via shared mechanisms remains to be determined. In considering secondary outcomes, the current literature suggests cannabinoids improve quality of life, specifically sleep quality, and that SCS decreases opioid consumption, increases functional capacity, and decreases long-term healthcare costs. These findings, along with the high safety profiles of SCS and cannabinoids overall, incentivize further exploration of cannabinoids as an adjunctive therapy to SCS in the treatment of neuropathic and nociceptive pain.

Efficacy of acupuncture in the treatment of fibromyalgia.

PURPOSE OF REVIEW: Fibromyalgia is a highly prevalent chronic pain syndrome that affects up to 4% of the population and causes significant morbidity and disability, with an increasing associated cost. Though many approaches for treatment have been tested, therapy regimens are still elusive, and efficacy is limited. This review summarizes the background of fibromyalgia and acupuncture and reviews the latest and seminal literature discussing the application of acupuncture in fibromyalgia. RECENT FINDINGS: Fibromyalgia is hard to treat, owing both to its chronicity and poorly understood pathophysiology and etiology. Current treatments target symptoms primarily, and few attempt to address the source. Efficacious treatment requires long-term treatment by a multidisciplinary team. Though several treatments exist, they still fall short with a substantial number of patients. Acupuncture, a form of integrative medicine, has been a part of traditional Chinese medication for generations. Evidence shows that it effectively treats different kinds of pain conditions, including migraines and chronic musculoskeletal pain. Recent studies showed evidence to support its use in fibromyalgia. Clinical trials studying acupuncture in fibromyalgia have shown improvement in pain, quality of sleep, and quality of life, though the quality of evidence is mainly low to medium. Several studies were not able to provide evidence to support real over sham acupuncture. Weighing the overall evidence paints a picture of mixed results between equivocal results to positive. In analyzing these results, one must also consider publication bias supporting the dissemination of positive results. SUMMARY: An increasing number of studies support the utilization of acupuncture for the treatment of fibromyalgia. Though no head-to-head comparison was able to show the superiority of acupuncture to other therapies, mounting evidence supports its use as part of multimodal approaches to treatment with additive efficacy to traditional therapy. Further research will likely provide data on effective regimens and combination therapies.

Adjuvant Drugs for Peripheral Nerve Blocks: The Role of Alpha-2 Agonists, Dexamethasone, Midazolam, and Non-steroidal Anti-inflammatory Drugs.

Adjuvant drugs for peripheral nerve blocks are a promising solution to acute postoperative pain and the transition to chronic pain treatment. Peripheral nerve blocks (PNB) are used in the brachial plexus, lumbar plexus, femoral nerve, sciatic nerve, and many other anatomic locations for site-specific pain relief. However, the duration of action of a PNB is limited without an adjuvant drug. The use of non-opioid adjuvant drugs for single-shot peripheral nerve blocks (sPNB), such as alpha-2 agonists, dexamethasone, midazolam, and non-steroidal anti-inflammatory drugs, can extend the duration of local anesthetics and reduce the dose-dependent adverse effects of local anesthetics. Tramadol is a weak opioid that acts as a central analgesic. It can block voltage-dependent sodium and potassium channels, cause serotonin release, and inhibit norepinephrine reuptake and can also be used as an adjuvant in PNBs. However, tramadol's effectiveness and safety as an adjuvant to local anesthetic for PNB are inconsistent. The effects of the adjuvants on neurotoxicity must be further evaluated with further studies to delineate the safety in their use in PNB. Further research needs to be done. However, the use of adjuvants in PNB can be a way to help control postoperative pain.
