Aduhelm, a novel anti-amyloid monoclonal antibody, for the treatment of Alzheimer's Disease: A comprehensive review.

Alzheimer's disease (AD) is the most common form of dementia affecting millions of individuals, including family members who often take on the role of caregivers. This debilitating disease reportedly consumes 8% of the total United States healthcare expenditure, with medical and nursing outlays accounting for an estimated $290 billion. Cholinesterase inhibitors and N-methyl-D-aspartate receptor antagonists have historically been the most widely used pharmacologic therapies for patients with AD; however, these drugs are not curative. The present investigation describes the epidemiology, pathophysiology, risk factors, presentation, and current treatment of AD followed by the role of the novel monoclonal antibody, Adulhelm, in the treatment of AD. Currently, Adulhelm is the only Food and Drug Administration (FDA) approved drug that acts to slow the progression of this disease. Adulhelm is an anti-amyloid drug that functions by selectively binding amyloid aggregates in both the oligomeric and fibrillar states. Studies show Adulhelm may help to restore neurological function in patients with AD by reducing beta-amyloid plaques and reestablishing neuronal calcium permeability. At present, there is concern the magnitude of this drug's benefit may only be statistically significant, although not clinically significant. Despite skepticism, Adulhelm has proven to significantly decrease amyloid in all cortical brain regions examined. With such high stakes and potential, further research into Adulhelm's clinical efficacy is warranted in the treatment of AD.

Opicapone, a Novel Catechol-O-methyl Transferase Inhibitor, for Treatment of Parkinson's Disease "Off" Episodes.

Parkinson's Disease (PD) is a common neurodegenerative disorder and the leading cause of disability. It causes significant morbidity and disability through a plethora of symptoms, including movement disorders, sleep disturbances, and cognitive and psychiatric symptoms. The traditional pathogenesis theory of PD involves the loss of dopaminergic neurons in the substantia nigra (SN). Classically, treatment is pursued with an assortment of medications that are directed at overcoming this deficiency with levodopa being central to most treatment plans. Patients taking levodopa tend to experience "off episodes" with decreasing medication levels, causing large fluctuations in their symptoms. These off episodes are disturbing and a source of morbidity for these patients. Opicapone is a novel, peripherally acting Catechol-O-methyl transferase (COMT) inhibitor that is used as adjunctive therapy to carbidopa/levodopa for treatment and prevention of "off episodes." It has been approved for use as an adjunct to levodopa since 2016 in Europe and has recently (April 2020) gained FDA approval for use in the USA. By inhibiting COMT, opicapone slows levodopa metabolism and increases its availability. Several clinical studies demonstrated significant improvement in treatment efficacy and reduction in duration of "off episodes." The main side effect demonstrated was dyskinesia, mostly with the 100mg dose, which is higher than the approved, effective dose of 50mg. Post-marketing surveillance and analysis are required to further elucidate its safety profile and contribute to patient selection. This paper reviews the seminal and latest evidence in the treatment of PD "off episodes" with the novel drug Opicapone, including efficacy, safety, and clinical indications.

Schmorl's Node: An Uncommon Case of Back Pain and Radiculopathy.

Background: Schmorl's nodes are herniations of nucleus pulposus through the cartilaginous and bony endplate into the adjacent vertebra. Schmorl's nodes are extremely common and are typically seen as incidental findings on radiographic imaging. In postmortem studies, it has been estimated that greater than 70% of the population has Schmorl's nodes. Rarely, however, Schmorl's nodes can be a cause of acute back pain and, even less often, radiculopathy. Case Presentation: In the present case, an elderly male presented with an acute onset of lower back pain and radiculopathy. MRI demonstrated a large L3 vertebral body inferior endplate Schmorl's node with posterior extension through the vertebral body cortex and into the ventral epidural space superiorly. This resulted in severe effacement of the right L2-L3 subarticular recess, as well as the right L3-L4 neural foramen, impinging on the right L3 nerve root. Surrounding cortical edema and enhancement on MRI further suggested an acute Schmorl's node. Conclusion: Although rare, Schmorl's nodes can be a cause of acute back pain and, even less commonly, radiculopathy. The imaging modality of choice for the diagnosis of a Schmorl's node is MRI as it has a greater capability to detect edema, neovascularization, and in this case, extruded disc material. In both asymptomatic and symptomatic cases, the mainstay of treatment for Schmorl's nodes is conservative therapy. Surgical removal of disc material has been successful in cases of persistent radiculopathy from compression by a tunneling Schmorl's node.

Principles of supply chain management in the time of crisis.

Hospitals face catastrophic financial challenges in light of the coronavirus disease 2019 (COVID-19) pandemic. Acute shortages in materials such as masks, ventilators, intensive care unit capacity, and personal protective equipment (PPE) are a significant concern. The future success of supply chain management involves increasing the transparency of where our raw materials are sourced, diversifying of our product resources, and improving our technology that is able to predict potential shortages. It is also important to develop a proactive budgeting strategy to meet supply demands through early designation of dependable roles to support organizations and through the education of healthcare staff. In this paper, we discuss supply chain management, governance and financing, emergency protocols, including emergency procurement and supply chain, supply chain gaps and how to address them, and the importance of communication in the times of crisis.

Lamotrigine and Stevens-Johnson Syndrome Prevention.

Stevens-Johnson Syndrome (SJS) is a rare life-threatening condition characterized by severe mucocutaneous epidermal necrolysis and detachment of the epidermis. The condition centers around a delayed-type hypersensitivity reaction with a complex etiology stemming from a variety of causes. The number one cause is medication-related-common ones including sulfonamides, antiepileptics, allopurinol, and nonsteroidal anti-inflammatory drugs. Genetics also play a role as several human leukocyte antigen (HLA) genotypes within certain ethnic groups have been implicated in adverse reactions to specific drugs. HLAB*15:02 has been identified in the Chinese and others of Southeast Asian origin to increase susceptibility to lamotrigine and carbamazepine-induced SJS. Furthermore, patients of Japanese origin with HLAB*31:01 and Koreans with HLA-B*44:03 are also at increased risk of SJS after receiving the same two drugs. Of the antiepileptics, one most commonly associated with SJS is lamotrigine, a pre-synaptic voltage-gated sodium channel inhibitor. Lamotrigine is an antiepileptic drug of the phenyltriazine class that is indicated for the prevention of focal and generalized seizures in epileptic patients as well as monotherapy or adjunctive maintenance treatment for Bipolar disorder. The occurrence of SJS is not a rigid contraindication to lamotrigine reintroduction in the same patient. To facilitate this, manufacturers have developed a strict re-challenge dosing regimen to facilitate successful reintroduction of lamotrigine. In order to prevent the recurrence of SJS during a re-challenge, timing of re-dose and initial rash severity must be considered. Therefore, to prevent SJS recurrence, prime lamotrigine re-challenge patients are those with mild initial rash that has not occurred within the previous 4 weeks. The Federal Food and Drug Administration recommends the testing HLA subtypes for those associated with SJS prior to starting lamotrigine.

Management of Lower Extremity Pain from Chronic Venous Insufficiency: A Comprehensive Review.

PURPOSE OF REVIEW: Chronic venous insufficiency is found to some extent in a large proportion of the world's population, especially in the elderly and obese. Despite its prevalence, little research has been pursued into this pathology when compared to similarly common conditions. Pain is often the presenting symptom of chronic venous insufficiency and has significant deleterious effects on quality of life. This manuscript will describe the development of pain in chronic venous insufficiency, and will also review both traditional methods of pain management and novel advances in both medical and surgical therapy for this disease. RECENT FINDINGS: Pain in chronic venous insufficiency is a common complication which remains poorly correlated in recent studies with the clinically observable extent of disease. Although lifestyle modification remains the foundation of treatment for pain associated with chronic venous sufficiency, compression devices and various pharmacologic agents have emerged as safe and effective treatments for pain in these patients. In patients for whom these measures are insufficient, recently developed minimally invasive vascular surgical techniques have been shown to reduce postsurgical complications and recovery time, although additional research is necessary to characterize long-term outcomes of these procedures. This review discusses the latest findings concerning the pathophysiology of pain in chronic venous insufficiency, conservative and medical management, and surgical strategies for pain relief, including minimally invasive treatment strategies.

Ubrogepant to Treat Acute Migraine in Adults.

Migraine is a neurobiological headache disorder that affects around 16% of adults in the United States. Medical treatment of mild to moderate migraines include non-prescription non-steroidal anti-inflammatory drugs, acetaminophen, or aspirin and caffeine-containing combination analgesics. Additionally, moderate to severe migraines and those that are mild to moderate that have not responded to analgesics can be treated with triptans, which are drugs specific for migraine treatment. Non-pharmacological treatments include cognitive behavioral therapy and relaxation training. Medications for the prevention of migraines have also been developed since they are more affective in offsetting the symptoms. Ubrogepant's high specificity and selectivity for calcitonin gene-related peptide (CGRP) sets it apart from certain other drugs, which previously limited the treatment of migraines with or without aura due to their decreased selectivity. The most frequently reported side effects are oropharyngeal pain, nasopharyngitis, and headache. Most studies found that participants receiving Ubrogepant were free from pain within 2 h when compared to placebo. Patients taking Ubrogepant should avoid taking it when pregnant or with end stage renal disease. In summary, Ubrogepant has good tolerability and an overall favorable safety profile. It appears to hold promise for the acute treatment of migraines with or without aura in adults.

Management of Acute and Chronic Pain Associated With Hidradenitis Suppurativa: A Comprehensive Review of Pharmacologic and Therapeutic Considerations in Clinical Practice.

Hidradenitis suppurativa (HS), a chronic, inflammatory, recurrent cutaneous disorder of the hair follicles, is debilitating and has substantial morbidity. Hidradenitis suppurativa-related pain has a profound effect on patient quality of life, yet at present, there are no established pain management algorithms. This comprehensive review provides an update on current treatment of HS-associated pain, including a summary of existing literature surrounding pharmacologic treatments of acute, perioperative, and chronic pain. Additionally, the epidemiology, pathophysiology, and clinical features of the disease are summarized.

Ozanimod to Treat Relapsing Forms of Multiple Sclerosis: A Comprehensive Review of Disease, Drug Efficacy and Side Effects.

Multiple sclerosis (MS) is a prevalent and debilitating neurologic condition characterized by widespread neurodegeneration and the formation of focal demyelinating plaques in the central nervous system. Current therapeutic options are complex and attempt to manage acute relapse, modify disease, and manage symptoms. Such therapies often prove insufficient alone and highlight the need for more targeted MS treatments with reduced systemic side effect profiles. Ozanimod is a novel S1P (sphingosine-1-phosphate) receptor modulator used for the treatment of clinically isolated syndrome, relapsing-remitting, and secondary progressive forms of multiple sclerosis. It selectively modulates S1P1 and S1P5 receptors to prevent autoreactive lymphocytes from entering the CNS where they can promote nerve damage and inflammation. Ozanimod was approved by the US Food and Drug Administration (US FDA) for the management of multiple sclerosis in March 2020 and has been proved to be both effective and well tolerated. Of note, ozanimod is associated with the following complications: increased risk of infections, liver injury, fetal risk, increased blood pressure, respiratory effects, macular edema, and posterior reversible encephalopathy syndrome, among others. Further investigation including head-to-head clinical trials is warranted to evaluate the efficacy of ozanimod compared with other S1P1 receptor modulators.

Chronic Pain Treatment Strategies in Parkinson's Disease.

Neurological disorders, including Parkinson's disease (PD), have increased in prevalence and are expected to further increase in the coming decades. In this regard, PD affects around 3% of the population by age 65 and up to 5% of people over the age of 85. PD is a widely described, physically and mentally disabling neurodegenerative disorder. One symptom often poorly recognized and under-treated by health care providers despite being reported as the most common non-motor symptom is the finding of chronic pain. Compared to the general population of similar age, PD patients suffer from a significantly higher level and prevalence of pain. The most common form of pain reported by Parkinson's patients is of musculoskeletal origin. One of the most used combination drugs for PD is Levodopa-Carbidopa, a dopamine precursor that is converted to dopamine by the action of a naturally occurring enzyme called DOPA decarboxylase. Pramipexole, a D2 dopamine agonist, and apomorphine, a dopamine agonist, and Rotigotine, a dopamine receptor agonist, have showed efficacy on PD-associated pain. Other treatments that have shown efficacy in treating pain of diverse etiologies are acetaminophen, Nonsteroidal anti-inflammatory drugs (NSAIDs), and cyclooxygenase-2 (COX-2) inhibitors. Opioids and opioid-like medications such as oxycodone, morphine, tramadol, and codeine are also commonly employed in treatment of chronic pain in PD. Other opioid related medications such as Tapentadol, a central-acting oral analgesic with combined opioid and noradrenergic properties, and Targinact, a combination of the opioid agonist oxycodone and the opioid antagonist naloxone have shown improvement in pain. Anticonvulsants such as gabapentin, pregabalin, lamotrigine, carbamazepine and tricyclic antidepressants (TCAs) can be trialed when attempting to manage chronic pain in PD. The selective serotonin and noradrenaline reuptake inhibitors (SNRIs) also possess pain relieving and antidepressant properties, but carry less of the risk of anticholinergic side effects seen in TCAs. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been shown in multiple studies to be effective against various types of PD associated pain symptoms. Massage therapy (MT) is one of the most common forms of complementary and alternative medicine. Studies have shown that pressure applied during MT may stimulate vagal activity, promoting reduced anxiety and pain, as well as increasing levels of serotonin. In a survey study of PD patients, rehabilitative therapy and physical therapy were rated as the most effective for pain reduction, though with only temporary relief but these studies were uncontrolled. Yoga has been studied for patients with a wide array of neurological disorders. In summary, PD pathology is thought to have a modulating effect on pain sensation, which could amplify pain. This could help explain a portion of the higher incidence of chronic pain felt by PD patients. A treatment plan can be devised that may include dopaminergic agents, acetaminophen, NSAIDs, opioids, antidepressants, physical therapies, DBS and other options discussed in this review. A thorough assessment of patient history and physical examination should be made in patients with PD so chronic pain may be managed effectively.

The utilization of buprenorphine in chronic pain.

Reclassification of chronic pain as a disease may be helpful because patients with chronic pain require significant treatment and rehabilitation with a clear diagnosis. This can help address critical factors including suffering, quality of life, participation, and with family and social life, which continue to become more important in evaluating the quality of the health care we give our patients today. During the past decade of the opioid epidemic, methadone was the primary treatment for opioid addiction until buprenorphine was approved. Buprenorphine's high-affinity partial agonist properties make it a good alternative to methadone due to lower abuse potential and safer adverse effect profile while maintaining significant efficacy. Expanded out-patient prescribing options have allowed physician and physician extenders such as physician assistants and nurse practitioners to treat these patients that otherwise would have been required to utilize methadone. With unique pharmacological properties, buprenorphine is a safe and effective analgesic for chronic pain. The literature for buprenorphine shows great potential for its utilization in the treatment of chronic pain.

The use of antineuropathic medications for the treatment of chronic pain.

Chronic pain syndromes cost the US healthcare system over $600 billion per year. A subtype of chronic pain is neuropathic pain (NP), which is defined as "pain caused by a lesion or disease of the somatosensory system," according to the International Association for the Study of Pain (IASP). The pathophysiology of neuropathic pain is very complex, and more research needs to be done to find the exact mechanism. Patients that have preexisting conditions such as cancer and diabetes are at high-risk of developing NP. Many NP patients are misdiagnosed and receive delayed treatment due to a lack of a standardized classification system that allows clinicians to identify, understand, and utilize pain management in these patients. Medications like tricyclic antidepressants, serotonin-norepinephrine reuptake Inhibitor (SNRIs), and gabapentinoids are first-line treatments followed by opioids, cannabinoids, and other drugs. There are limited studies on the treatment of NP.

Exparel for Postoperative Pain Management: a Comprehensive Review.

PURPOSE OF REVIEW: Multimodal pain management is the most effective way to treat postsurgical pain. However, the use of opioids for acute pain management has unfortunately been a significant contributor to the current opioid epidemic. The use of opioids should be limited and only considered a "rescue" pain medication after other modalities of pain management have been utilized. RECENT FINDINGS: It may be difficult to curtail the use of opioids in the treatment of chronic pain; however, in the postsurgical setting, there is compelling evidence that an opioid-centric analgesic approach is not necessary for good patient outcomes and healthcare cost benefits. Opioid-related adverse effects are the leading cause of preventable harm in the hospital setting. After the realization in recent years of the many harmful effects of opioids, alternative regimens including the use of multimodal analgesia have become a standard practice in acute pain management. Exparel, a long-lasting liposomal bupivacaine local anesthetic agent, has many significant benefits in the management of postoperative pain. Overall, the literature suggests that Exparel may be a significant component for postoperative multimodal pain control owing to its efficacy and long duration of action.

Overview of Stem Cell Therapy for Acute Respiratory Distress Syndrome with Focus on COVID 19.

OBJECTIVE: There are as yet no effective strategies to treat the novel COVID-19 and to stem its symptoms, including ARDS. This review examines recent research studies in humans to determine whether mesenchymal stem cells (MSCs) may be used effectively and safely to target potentially deadly lung damage that may follow infection. METHODS: A literature search was conducted to find published manuscripts on the treatment of ARDS and COVID-19 symptoms, disease presentation, and available treatment regimens. Electronic data bases of scientific articles and records of printed documents of JAMA journals were searched to find research publications on MSC treatment of ARDS and COVID-19. Outcome variables included mortality over varying time periods, hospital days, days on ventilator, and biological factors. RESULTS: Two randomized double-blind clinical trials, 2 pilot studies, and 2 case reports described MSC use to treat ARDS with specific focus on COVID-19 and lung symptoms of cytokine storm. The MSCs were well-tolerated across studies. No significant differences in treatment outcome were found in randomized double-blind trials; however, results of 1 pilot study and 1 case report showed that MSCs led to lung symptom resolution and survival in severely ill treatment patients. CONCLUSIONS: There is little published research on disease and survival outcomes among patients suffering severe lung disease associated with ARDS and COVID-19, and studies available are limited by lack of consistency in design and numerous flaws and limitations. Comparisons across studies are difficult. Nevertheless, it is documented that 8 ARDS patients with COVID-19 experienced symptom recovery and survival subsequent to MSC administration. MSCs are potentially life-saving treatment approaches for some patients who exhibit severe lung distress and have not responded to standard treatments. This is an obviously exciting research and treatment option for COVID-19 and other life-threatening diseases.

Current Concepts of Minimally Invasive Treatment Options for Plantar Fasciitis: a Comprehensive Review.

PURPOSE OF REVIEW: Chronic foot pain constitutes a large portion of the chronic pain burden in the overall population. Plantar fasciitis is one of the most common and most easily identifiable causes of chronic foot pain. The syndrome has been estimated to cause 11 to 15% of foot pain visits, requiring professional care. Moreover, studies have suggested that 1 in 10 people will develop plantar fasciitis at some point in their life. Conservative management has been shown to be effective and considered first-line treatment. Minimally invasive treatment options are typically reserved for those who fail conservative management. With the advent of new techniques and improvements in current therapeutic options, there has been an expansion of available minimally invasive treatment options. The purpose of this review is to provide a comprehensive update on the current understanding of minimally invasive treatments of plantar fasciitis. RECENT FINDINGS: This review shows that conservative management continues to be the first-line therapy, whereas other treatment options were those who failed conservative management using modern techniques that have shown improving effectiveness, with successful restoration of patient functionality, recovery, and satisfaction. However, a multitude of these minimally invasive treatment options are evolving. CONCLUSION: While conservative management continues to be the mainstay of treatment for plantar fasciitis, multiple minimally invasive treatment options are emerging with potential effectiveness in reducing pain and improving the function.

Diagnosis, Treatment, and Management of Dejerine-Roussy Syndrome: a Comprehensive Review.

PURPOSE OF REVIEW: Post-stroke pain represents a complex condition with few standardized diagnostic criteria. As such, the array of symptoms is often difficult to categorize and diagnose. Central post-stroke pain (CPSP), also known as Dejerine-Roussy syndrome, presents as painful paresthesia in any part of the body that is usually coupled with sensory abnormalities. RECENT FINDINGS: In patients who had experienced a cerebrovascular accident, CPSP typically affects the same areas of the body that are also impacted by the general motor and sensory deficits that result from stroke. Though it is generally debated, CPSP is thought to result from a lesion in any part of the central nervous system. Pain usually presents in the range of 3-6 months after the occurrence of stroke, manifesting contralaterally to the lesion, and most commonly involving the upper extremities. For the most accurate diagnosis of CPSP, a thorough history and clinical examination should be supplemented with imaging. Infarcted areas of the brain can be visualized using either CT or MRI. First-line treatment of CPSP is pharmacologic and consists of a three-drug regimen. Despite this, CPSP is often refractory to medical management producing only modest pain reduction in a limited subset of patients. Adverse effects associated with pharmacologic management of CPSP and frequent recalcitrance to treatment have driven alternative minimally invasive methods of pain control which include transcranial stimulation, deep brain stimulation, and neuromodulation. The aim of this review is to provide a comprehensive update to recent advances in the understanding of the treatment and management of CPSP.

Perioperative strategies for the reduction of postoperative pulmonary complications.

Postoperative pulmonary complications (PPCs), estimated between 2.0% and 5.6% in the general surgical population and 20-70% for upper abdominal and thoracic surgeries, are a significant factor leading to poor patient outcomes. Efforts to decrease the incidence of PPCs such as bronchospasm, atelectasis, exacerbations of underlying chronic lung conditions, infections (bronchitis and pneumonia), prolonged mechanical ventilation, and respiratory failure, begins with a detailed preoperative risk evaluation. There are several available preoperative tests to estimate the risk of PPCs. However, the value of some of these studies to estimate PPCs remains controversial and is still debated. In this review, the preoperative risk assessment of PPCs is examined along with preoperative pulmonary tests to estimate risk, intraoperative, and procedure-associated risk factors for PPCs, and perioperative strategies to decrease PPCs. The importance of minimizing these events is reflected in the fact that nearly 25% of postoperative deaths occurring in the first week after surgery are associated with PPCs. This review provides important information to help clinical anesthesiologists to recognize potential risks for pulmonary complications and allows strategies to create an appropriate perioperative plan for patients.

A Comprehensive Review of the Celiac Plexus Block for the Management of Chronic Abdominal Pain.

PURPOSE OF REVIEW: Chronic abdominal pain (CAP) is a significant health problem that can dramatically affect quality of life and survival. Pancreatic cancer is recognized as one of the most painful malignancies with 70-80% suffering from substantial pain, often unresponsive to typical medical management. Celiac plexus neurolysis and celiac plexus block (CPB) can be performed to mitigate pain through direct destruction or blockade of visceral afferent nerves. The objective of this manuscript is to provide a comprehensive review of the CPB as it pertains to CAP with a focus on the associated anatomy, indications, techniques, neurolysis/blocking agents, and complications observed in patients who undergo CPB for the treatment of CAP. RECENT FINDINGS: The CAP is difficult to manage due to lack of precision in diagnosis and limited evidence from available treatments. CAP can arise from both benign and malignant causes. Treatment options include pharmacologic, interventional, and biopsychosocial treatments. Opioid therapy is typically utilized for the treatment of CAP; however, opioid therapy is associated with multiple complications. CPB has successfully been used to treat a variety of conditions resulting in CAP. The majority of the literature specifically related to CPB is surrounding chronic pain associated with pancreatic cancer. The literature shows emerging evidence in managing CAP with CPB, specifically in pancreatic cancer. This review provides multiple aspects of CAP and CPB, including anatomy, medical necessity, indications, technical considerations, available evidence, and finally complications related to the management.

A Comprehensive Review of the Diagnosis, Treatment, and Management of Postmastectomy Pain Syndrome.

PURPOSE OF REVIEW: Postmastectomy pain syndrome (PMPS) remains poorly defined, although it is applied to chronic neuropathic pain following surgical procedures of the breast, including mastectomy and lumpectomy in breast-conserving surgery. It is characterized by persistent pain affecting the anterior thorax, axilla, and/or medial upper arm following mastectomy or lumpectomy. Though the onset of pain is most likely to occur after surgery, there may also be a new onset of symptoms following adjuvant therapy, including chemotherapy or radiation therapy. RECENT FINDINGS: The underlying pathophysiology is likely multifactorial, although exact mechanisms have yet to be elucidated. In this regard, neuralgia of the intercostobrachial nerve is currently implicated as the most common cause of PMPS. Numerous pharmacological options are available in the treatment of PMPS, including gabapentinoids, tricyclic antidepressants, selective serotonin reuptake inhibitors, NMDA receptor antagonists, and nefopam (a non-opioid, non-steroidal benzoxazocine analgesic). Minimally invasive interventional treatment including injection therapy, regional anesthesia, botulinum toxin, and neuromodulation has been demonstrated to have some beneficial effect. A comprehensive update highlighting current perspectives on the treatment of postmastectomy pain syndrome is presented with emphasis on treatments currently available and newer therapeutics currently being evaluated to alleviate this complex and multifactorial condition.

Considerations and Implications of Cannabidiol Use During Pregnancy.

PURPOSE OF REVIEW: Cannabis is a naturally occurring plant that is composed of over sixty phytocannabinoids, of which cannabidiol (CBD) has been recently identified as having therapeutic potential. RECENT FINDINGS: Although not clearly understood in its mechanism of action, CBD contains potent anti-inflammatory, anti-hyperalgesia, and analgesic qualities now being further analyzed for its use in the treatment of a plethora of diseases. Related to its large safety profile and lack of psychoactive effects typically associated with cannabis and tetrahydrocannabinol (THC), CBD is being used more frequently for self-treatment of chronic pain, anxiety, and depression. With the help of broad marketing, CBD is being used by numerous people, including pregnant women who use CBD as an anti-emetic. Since marijuana is legalized in many states in the USA, the use of CBD has increased not only in the general population but also in specific groups such as pregnant women with chronic pain. Despite CBD's accessibility, there are limited studies showing its safety during pregnancy. While the use of cannabis has been well explored in terms of the effects on pregnancy, the use of CBD during pregnancy thus far has limited literature. The goal of this investigation is to impart the current understanding of CBD and its effects of pregnancy.
