Vertebral artery dissection (VAD) is a common cause of stroke in young and mid-aged adults without predisposing risk factors for vascular disease. It can be induced by a particular head or neck posture; its early signs often include headache and neck pain. Improved imaging techniques can be used to detect VAD, whose current treatment options are limited.

The "opioid crisis" stemming from overprescribing of prescription opioids describes an iatrogenic situation which has resulted in a rise in opioid use disorder (OUD) and overdose deaths. Many of these patients suffer from chronic non-cancer pain syndromes (CNCP) who have been injudiciously treated with opioids. Some patients with CNCP are treated successfully with opioids in accordance with modern guidelines. There is a very complex, small group of patients with CNCP who require higher than recommended dosages of opioids when other modalities and treatments have failed. We describe such a patient and believe that there is a subset of patients with unremitting suffering from chronic pain which we have called end-stage chronic pain (ESCP). These patients, despite receiving expert chronic pain care, often require high doses of opioids and suffer a dramatic decline in quality of life (QOL), function and an increase in their suffering when their opioids are tapered or discontinued. We have responded to the treatment of this group of patients by critically examining our approach to the use of opioids for their pain and attempting to reconcile high dose opioids in the setting of the Center for Disease Control (CDC) guidelines. We describe a patient with severe chronic pain from congenital spinal disease who experienced increased pain and suffering when his opioids were tapered. We will discuss our approach to this patient and in doing so discuss the concept of ESCP and proposed criteria for the use of high dose opioids in such patients.

Inconsistent results have been obtained regarding postoperative pain control using local infiltration and epidural analgesia for patients after total knee or hip arthroplasty (TKA and THA). We therefore conducted a meta-analysis of randomized controlled trials (RCTs) to assess the efficacy and safety of local infiltration vs epidural analgesia for TKA and THA.

The coronavirus disease 2019 (COVID-19) pandemic has rapidly transformed the whole world and forced us to look through comorbid diseases and risk factors from a different perspective. COVID-19 shows some inherent risk factors like cardiovascular comorbidities independent from age, gender, and geographic location. One of the most peculiar features of the COVID-19 pandemic is that severe acute respiratory syndrome coronavirus 2 respiratory infections disproportionately impact patients with hypertension, diabetes, and other cardiovascular comorbidities rather than those with allergic respiratory diseases and immune-compromised conditions. Migraine is a complex neuro-vasculo-inflammatory disorder that is also packed frequently with certain medical conditions including vascular disorders, hypertension, allergic diseases such as asthma and systemic inflammatory disorders. Accordingly, 2 different questions arise during the pandemic: (1) Do share comorbidities of cardiovascular diseases and hypertension increase the risk of symptomatic COVID-19 for migraine patients? (2) Do comorbid allergic and atopic diseases, including asthma act as opposite influencers alongside with female gender? This paper focuses on the co-existence of comorbidities of COVID-19, in comparison with migraine, based on a wide clinical dataset and available reports. Discussed mechanisms include potential strategic roles of angiotensin-converting enzyme 2, angiotensin-II, and nucleotide oligomerization domain-like receptor family, pyrin domain containing 3 inflammasome, playing remarkable parts in the pathogenesis of COVID-19 and migraine. There are also some clues about the importance of endothelial and pericyte dysfunction and neuroinflammation in COVID-19 infection, related to complications and survival of the patients. The large epidemiological studies as well as basic research, focusing on migraine patients with COVID-19 will clarify these vital questions during the upcoming periods.

Trigeminocardiac reflex (TCR) sometimes occurs during the percutaneous balloon compression (PBC) procedure to treat trigeminal neuralgia (TN), and it manifests as transient bradycardia or sinus arrest. However, recurrent intraoperative TCR cases are rarely reported. Meanwhile, the treatment for recurrent TCR is still unclear.

Sub-optimal opioid prescribing and use is viewed as a major contributor to the growing opioid crisis. This study aims to systematically review the nature, process and outcomes of interventions to optimize prescribed medicines and reduce their misuse in chronic non-malignant pain (CNMP) with a particular focus on minimizing misuse of opiates.

On August 11, 2020, a confirmed case of coronavirus disease 2019 (COVID-19) in a male correctional facility employee (correctional officer) aged 20 years was reported to the Vermont Department of Health (VDH). On July 28, the correctional officer had multiple brief encounters with six incarcerated or detained persons (IDPs)* while their SARS-CoV-2 test results were pending. The six asymptomatic IDPs arrived from an out-of-state correctional facility on July 28 and were housed in a quarantine unit. In accordance with Vermont Department of Corrections (VDOC) policy for state prisons, nasopharyngeal swabs were collected from the six IDPs on their arrival date and tested for SARS-CoV-2, the virus that causes COVID-19, at the Vermont Department of Health Laboratory, using real-time reverse transcription-polymerase chain reaction (RT-PCR). On July 29, all six IDPs received positive test results. VDH and VDOC conducted a contact tracing investigation and used video surveillance footage to determine that the correctional officer did not meet VDH's definition of close contact (i.e., being within 6 feet of infectious persons for ≥15 consecutive minutes); therefore, he continued to work. At the end of his shift on August 4, he experienced loss of smell and taste, myalgia, runny nose, cough, shortness of breath, headache, loss of appetite, and gastrointestinal symptoms; beginning August 5, he stayed home from work. An August 5 nasopharyngeal specimen tested for SARS-CoV-2 by real-time RT-PCR at a commercial laboratory was reported as positive on August 11; the correctional officer identified two contacts outside of work, neither of whom developed COVID-19. On July 28, seven days preceding his illness onset, the correctional officer had multiple brief exposures to six IDPs who later tested positive for SARS-CoV-2; available data suggests that at least one of the asymptomatic IDPs transmitted SARS-CoV-2 during these brief encounters.

Mixtures of gabapentin, tramadol and/or amitriptyline are usually recommended for treatment of neuropathic pain. A novel GC-MS/MS method was developed to assess the studied mixture whether in pure forms or human biological fluids (plasma/urine). The chromatographic detection was performed using MS detector applying the selected ion-monitoring mode. An (Agilent, CA, USA) GC-MS with triple axis single quadrupole detector unit was used for the analysis equipped with HP-5MS (5% phenyl methyl siloxane) column. Helium was the carrier gas and positive electron impact ionization mode was applied. The developed method was able to assess the mixture components simultaneously within six minutes. Validation of the method was assured according to US FDA guidelines and Eco-Scale assessment.
