Electrical stimulation of peripheral nerves is a widely used technique to treat a variety of conditions including chronic pain, motor impairment, headaches, and epilepsy. Nerve stimulation to achieve efficacious symptomatic relief depends on the proper selection of electrical stimulation parameters to recruit the appropriate fibers within a nerve. Recently, electrical stimulation of the vagus nerve has shown promise for controlling inflammation and clinical trials have demonstrated efficacy for the treatment of inflammatory disorders. This application of vagus nerve stimulation activates the inflammatory reflex, reducing levels of inflammatory cytokines during inflammation.

A 38-year-old African American male presented with progressive pain, swelling, numbness, and warmth of the left upper extremity ten days before admission. A chest computerized tomography scan showed a large 8.3 cm × 6.1 cm x 9.9 cm anterior mediastinal mass with compression of the left brachiocephalic vein and superior vena cava. A venous doppler showed multiple occlusive venous thrombi in bilateral upper extremities, including the bilateral internal jugular and subclavian veins, as well as the left subclavian, axillary, cephalic, brachial and median cubital veins. Further laboratory workup came positive for acetylcholine receptor binding antibody suggesting myasthenia gravis, but the patient was asymptomatic for myasthenia gravis. A percutaneous core CT guided biopsy pathology resulted in a predominant T-cell population CD5 positive with few B cells; the immunophenotypic features suggested Type B2 thymoma. To the best of our knowledge, this case is the only reported thymoma presenting with bilateral deep vein thrombosis of the upper extremities. The deep vein thrombosis therapy was enoxaparin 1mg/kg subcutaneously every 12 hours and dexamethasone 4mg intravenously every 4 hours as an anti-inflammatory drug for thymoma related compression of the mediastinum. The patient was referred to a tertiary oncological medical center for a total thymectomy, chemotherapy, and adjuvant radiotherapy.

The study was undertaken to evaluate efficacy of comprehensive treatment with the use of erbium laser radiation in patients suffering from venous trophic ulcers of lower limbs.

The thrombopoietin receptor agonist eltrombopag has been shown to be safe and effective for children with chronic immune thrombocytopenia (ITP). The aim of the present study was to characterize eltrombopag use in current clinical practice. This is a retrospective multicenter study conducted in 17 centers affiliated to the Italian Association of Pediatric Hematology and Oncology (AIEOP). The primary objective of the study was to determine the prevalence of eltrombopag use in Italian children affected by chronic ITP, after EMA authorization for pediatric age. The secondary objective was to assess efficacy in the first 6 months and safety during the whole period of eltrombopag treatment in current clinical practice. A total of 386 children with chronic ITP were retrospectively enrolled and eligible for analysis. Among these patients, 71 received eltrombopag. The prevalence of eltrombopag use was 19% (95% CI 0.15-0.23). Thirty-one patients (44%) were male and 40 patients (56%) were female. The median age at the first dose of eltrombopag was 12 years (3-17 years). The median duration of eltrombopag treatment was 11 months (1-32 months) and the median starting dose was 50 mg/day (12, 5-75 mg/day). Thirty-two patients (45%) required one or more concomitant ITP medications during the first 6 months of treatment with eltrombopag. Thirty-nine patients (55%) never required concomitant medications. Median platelet counts and proportion of patients achieving the target platelet count of at least 30 × 10/L and 100 × 10/L significantly increased during the first 6 months of treatment ( < 0.0001). Additionally, eltrombopag has been proved effective in the absence of concomitant therapies. The most common Adverse Events were headache (7%) and thrombocytosis (6%). Our study highlighted the crucial role of eltrombopag as second line treatment in children with chronic ITP.

Traumatic brain injury (TBI) represents an important public health problem and is followed by neuroinflammation and neurological dysfunctions. It has been suggested that brain trauma is often associated to deep behavioral alterations and chronic pain-like syndrome. Despite inducing minimal brain damage, mild TBI (mTBI) leads to persistent behavioral changes, including anxiety, depression, social interaction impairment, and aggressiveness. The clinical management of these symptoms is still unsatisfactory and new pharmacological treatments are needed, especially for the aggressiveness and depression. In a mouse model of mTBI, we investigated the effect of 2-Pentadecyl-2-Oxazoline (PEA-OXA), a natural compound, that is a secondary metabolite, found in green and roasted coffee beans, on both the pain perception, and neuropsychiatric dysfunctions. We found that the compound acts as a α2 adrenergic antagonist and this mechanism is here described for the first time. Mild TBI mice, starting from 14-d post-trauma, developed anxious and aggressive behavior, whilst depressive-like behavior and impaired social interactions were observed from the 60th d onward. PEA-OXA normalized all the behavioral changes investigated. We also investigated the memory impairments through Morris Water Maze (MWM) test. Both sham and mTBI mice treated with PEA-OXA showed amelioration in the reversal task of the MWM. Nevertheless, the main symptom of the long-term mTBI is represented by the depressive-like behavior, which was completely reversed by PEA-OXA repeated administration. In humans, mTBI-induced depression precedes the appearance of dementias and is characterized by a massive deficit of GABAergic transmission in the cortices. We found that PEA-OXA normalized the GABA changes in the prefrontal cortex. In order to prove the α2-mediated effect of the PEA-OXA we have performed open field test in naïve animals by microinjecting into the medial prefrontal cortex the dexomedetomidine, a selective α2 agonist with or without PEA-OXA co-injection. We found that PEA-OXA antagonized the α2 agonist effect on the locomotor activity. Moreover, PEA-OXA microinjection into the medial prefrontal cortex induced an enhancement of dopamine release. Collectively, these data suggest that this natural compound, through its multi-target activity is able to: i) ameliorate behavioral alterations (i.e. depression), ii) selectively normalize cortical GABA levels, iii) rescue the impaired neuronal activity in the prefrontal cortex.

Over the past two decades, there has been a sharp rise in the use of prescription opioids. In several countries, most notably the United States, opioid-related harm has been deemed a public health crisis. As surgeons are among the most prolific prescribers of opioids, growing attention is now being paid to the role that opioids play in surgical care. While opioids may sometimes be necessary to provide patients with adequate relief from acute pain after major surgery, the impact of opioids on the quality and safety of surgical care calls for greater scrutiny. This narrative review summarizes the available evidence on rates of persistent postsurgical opioid use and highlights the need to target known risk factors for persistent postoperative use before patients present for surgery. We draw attention to the mounting evidence that preoperative opioid exposure places patients at risk of persistent postoperative use, while also contributing to an increased risk of several other adverse clinical outcomes. By discussing the prevalence of excess opioid prescribing following surgery and highlighting significant variations in prescribing practices between countries, we note that there is a pressing need to optimize postoperative prescribing practices. Guided by the available evidence, we call for specific actions to be taken to address important research gaps and alleviate the harms associated with opioid use among surgical patients.

Even though the type, extent and reasons for self-medication practice (SMP) vary, globally self-medication (SM) is rising to relieve burdens on health services. However, inappropriate SMP results in economic wastes, damage of vital organs, incorrect therapy selection, risk of adverse drug reactions and development of antimicrobial-resistant pathogens. These consequences have severe implications including legal, ethical and quality of health-care delivery. Temporal increment and high prevalence of SM among health professionals is also a major bottleneck for Ethiopia. Hence, the study aimed to assess the SM among health-care professionals (HCPs) in selected governmental hospitals of Western Ethiopia.

Studies have proven that improving patients' acceptance of chronic pain could be an effective therapy for alleviating pain and other symptoms. Our objectives were to investigate the correlation between chronic pain acceptance and clinical variables in ankylosing spondylitis (AS), and the prediction role of chronic pain acceptance for biologics treatment. First, 167 AS patients were recruited to complete a series of questionnaires, including the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Chronic Pain Acceptance Questionnaire (CPAQ), Hospital Anxiety and Depression Scale (HADS), and Tampa Scale for Kinesiophobia (TSK). Bivariate correlation analysis was utilized to investigate the correlation between pain acceptance and clinical variables. Based on the level of chronic pain acceptance and serum C-reactive protein (CRP), patients were separated into four subgroups. Then, another 68 patients initiating anti-tumor necrosis factor (TNF) treatment were recruited to complete the questionnaires at baseline (T0) and 3 months after treatment (T3). The changes in clinical variables and treatment response were compared between multiple subgroups. Chronic pain acceptance had strong correlations with anxiety, depression and fear of movement, and moderate correlations with BASFI and pain intensity. Both activity engagement (AE) and pain willingness (PW) had significant correlations with pain intensity, BASFI and psychological status. In addition, AE had a significant correlation with disease duration, while PW had a significant correlation with ASDAS-CRP. Subgroup analysis showed that patients with low chronic pain acceptance and high levels of serum CRP had the highest BASDAI. Among patients initiating anti-TNF treatment, those with high pain acceptance and high levels of serum CRP achieved the most obvious reduction in BASDAI after 3 months treatment. Pain acceptance is a new tool to assess pain in AS which may also reflect physical and psychological status. Clinicians should identify high-risk patients with low chronic pain acceptance and high levels of serum CRP, and give psychological and pharmacological intervention promptly. Moreover, the combination of baseline chronic pain acceptance and serum CRP level could be used to predict the treatment response in AS patients initiating biologics treatment.

Venom-derived peptides display diverse biological and pharmacological activities that make them useful in a wide range of applications in medicine and pharmaceutical biotechnology. They have potential to treat various health problems such as diabetes mellitus, hypertension, chronic pain and others. Despite the high potential for new drug development, a number of limitations have been reported for these compounds, including chemical instability, poor oral absorption, short half-life and toxicity, which complicate the process of converting venom peptides into therapeutic agents. One possibility to overcome these disadvantages is to encapsulate these molecules into nanocarriers. Up to date, some venom-derived peptides have been loaded into different types of nanomaterials and promising results have achieved. The present work reports examples of these peptides and the types of nanocarriers used. Based on this review, information can be taken to select the best conditions and materials to encapsulate biologically active venom-derived peptides for pharmaceutical application.

Chronic neck pain (NP) attributed to myofascial pain syndrome is one of the particularly common skeletal muscle disorder associated with the hyperirritable zone in the taut band of muscle. Trigger points (TPs) are the physical interpretation of the myofascial pain syndrome. In the United States, 30%-85% of pain patients have been affected by myofascial TPs. To reveal preliminary evidence on the clinical efficacy of ischemic compression therapy, dry cupping, and their combination on improving the TPs' pressure pain threshold (PPT), neck range of motion (NROM), and neck disability index (NDI) in patients with TPs and nonspecific NP. Besides, assess the feasibility of conducting a randomized clinical trial (RCT). A randomized pilot study was conducted on 24 patients with TPs and nonspecific NP. Patients were randomly assigned to three groups: the cupping group, the ischemic compression group, and the combination therapy group. PPT, NROM, and NDI were assessed before and after 4 weeks of treatment. The results showed a statistically significant improvement in NDI, PPT, and NROM compared with values before the treatment ( < 0.05) in all groups. Although no significant difference was detected between ischemic compression (IC) and dry cupping, the combination approach showed significantly higher and faster improvement ( < 0.05). It is feasible to conduct a main RCT. Both IC and dry cupping may hold promise in treating TPs; a combination of the two therapies may provide superior improving rate.
