To analyze the clinical characteristics and therapeutic effects of transoral paraquat poisoning combined with Esophagitis dissecans superficialis (EDS). A retrospective observational study was conducted on paraquat poisoning patients between January 1, 2011 and August 30, 2016 in Qilu hospital. Fifteen patients with EDS were enrolled in this study. The clinical characteristics, prognosis, and pathological features of esophageal necrosis mucosa of these patients were retrospectively analyzed and summarized. Esophageal mucosal dissection occurs mainly within 3-8 days after transoral paraquat poisoning in 15 patients. Dosage of paraquat is range from 50 to 100 ml. Most patients have physical problems with swallowing before the intramural esophageal dissection occurred. And there are other symptoms, including sore throat or dysphagia (100%), nausea and vomiting (86.7%), heartburn or upper abdominal pain (73.3%), hematemesis (60%), abdominal distension (20%) and cough frequently (6.7%). In death group, most patients demonstrate features of the multiple organ failure when the esophageal mucosal stripping happened, including lung injury, renal failure, and hepatic failure. The shape of esophageal dissection was tubular in 60%, irregular in 40%, and they vary in size. Pathological examination showed extensive injury, necrosis and hemorrhage of digestive tract epithelium, and obvious inflammatory reaction of epithelial tissue. Transoral paraquat poisoning has certain damage to the patient's esophageal mucosa, and some may be complicated with EDS, and the prognosis is poor, especially when combined with multiple organ dysfunction. Esophageal damage is mainly located in the esophageal mucosa and have different degrees. Special attention should be paid on such patients.

To propose agile strategies for a comprehensive approach to analgesia, sedation, delirium, early mobility and family engagement for patients with COVID-19-associated acute respiratory distress syndrome, considering the high risk of infection among health workers, the humanitarian treatment that we must provide to patients and the inclusion of patients' families, in a context lacking specific therapeutic strategies against the virus globally available to date and a potential lack of health resources.

The limited access to opioids remains a reality in developing countries. Recent evidence suggests that opioid epidemics are getting worse with the COVID-19 crisis. The increase in opioid abuse could be attributed to the extended lockdowns and the social distancing recommendations, hindering chronic pain patients' access to regular office visits and monitoring in addition to limited access to behavioral services like group therapies and other pain management interventions. Use of telemedicine as an alternative to in-person follow-up visits has faced many limitations due to technological challenges and cost. Chronic pain patients living in developing countries face extra burden during the pandemic. Limited access to outpatient clinics and hesitance to visit hospitals due to COVID-19 pandemic, in addition to reduction in supply of opioids, are some of the limiting factors. Unfortunately, the low-income class with limited financial capabilities faces further barriers to access the chronic pain services and treatments like opioid prescriptions. Medical entities involved in care of chronic pain patients have adopted different strategies to overcome these challenges. In addition to expanding on educational programs to medical staff and patients, modifying the strict opioid pre-scribing and dispensing regulations has been successful. Another positive trend has been the growing use of opioid sparing interventions, such as multimodal analgesia, regional blocks, and interventional pain procedures.

Trigeminal neuralgia is a painful condition, usually treated through surgical procedures focusing on the foramen ovale (FO). A detailed localization of FO relative to reference landmarks is therefore crucial to avoid possible complications.The present study aims at assessing the position of FO according to the surrounding bone structures: 100 CT-scans of patients, equally divided between sexes, aged between 18 and 86 years were examined. From each subject, the 3D models of FO and the maxillary bones, the zygomatic bones and the zygomatic process of the temporal bones were segmented through ITK-SNAP software. The distance between the center of the FO and subnasale, zygion, and the upper edge of the zygomatic bone at the origin of the frontal process were measured on 3D models. On CT-scans three cranial measurements were taken as well (distance between anterior and posterior nasal spine, upper facial height and bizygomatic breadth).Statistically significant differences in the three distances according to side and sex were assessed through two-way ANCOVA test, using the three cranial measurements (ANS-PNS, NP, ZZ) as covariates (P < 0.05).Distances between the centre of FO and subnasale, zygion and the upper edge of the zygomatic bone were on average 82.3 ± 3.4 mm, 41.9 ± 2.6 mm and 48.8 ± 3.5 mm in males, 77.3 ± 3.9 mm, 38.2 ± 2.5 mm and 45.5 ± 3.1 mm in females, with a significant difference according to sex (P < 0.05).Results provide innovative data for the localization of FO and will be useful for the management of transforaminal procedures in case of trigeminal neuralgia.

The "Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)" disease has caused a worldwide challenging and threatening pandemic (COVID-19), with huge health and economic losses. The US Food and Drug Administration, (FDA) has granted emergency use authorization for treatment with the Pfizer/BioNTech and Moderna COVID-19 vaccines. Many people have a history of a significant allergic reaction to a specific food, medicine, or vaccine; hence, people all over the world have great concerns about these two authorized vaccines. This article compares the pharmacology, indications, contraindications, and adverse effects of the Pfizer/BioNTech and Moderna vaccines.

Spinal cord injury (SCI) usually leads to disconnection between traversing neuronal pathway. The impairment of neural circuitry and its ascending and descending pathway usually leave severe SCI patients with both motor disability and loss of sensory function. In addition to poor quality of life, SCI patients not only have disabling respiratory function, urinary retention, impaired sexual function, autonomic dysregulation but also medical refractory neuropathic pain in the long term. Some translational studies demonstrated that spinal networks possess a dynamic state of synaptic connection and excitability that can be facilitated by epidural spinal cord stimulation. In addition, preliminary human studies also confirmed that spinal cord stimulation enables stepping or standing in individuals with paraplegia as well. In this review, we examined the plausible interventional mechanisms underlying the effects of epidural spinal cord stimulation in animal studies. Following the success of translational research, chronic paralyzed subjects due to SCI, defined as motor complete status, regained their voluntary control and function of overground walking and even stepping for some. These progresses lead us into a new hope to help SCI patients to walk and regain their independent life again.

Inadequate pain relief after thoracotomy may lead to postoperative respiratory complications.

Varicella-zoster virus (VZV) establishes lifelong neuronal latency in most humans world-wide, reactivating in one-third to cause herpes zoster and occasionally chronic pain. How VZV establishes, maintains and reactivates from latency is largely unknown. VZV transcription during latency is restricted to the latency-associated transcript (VLT) and RNA 63 (encoding ORF63) in naturally VZV-infected human trigeminal ganglia (TG). While significantly more abundant, VLT levels positively correlated with RNA 63 suggesting co-regulated transcription during latency. Here, we identify VLT-ORF63 fusion transcripts and confirm VLT-ORF63, but not RNA 63, expression in human TG neurons. During in vitro latency, VLT is transcribed, whereas VLT-ORF63 expression is induced by reactivation stimuli. One isoform of VLT-ORF63, encoding a fusion protein combining VLT and ORF63 proteins, induces broad viral gene transcription. Collectively, our findings show that VZV expresses a unique set of VLT-ORF63 transcripts, potentially involved in the transition from latency to lytic VZV infection.

While there exists a substantial literature on the risk factors and clinical manifestations of cervical artery dissection (CeAD) including carotid and vertebral artery, little is known about postdissection recanalization. The goal of our study was to provide a descriptive analysis of CeAD and recanalization after dissection with neuroimaging follow up.

Best practices and training for prolonged field care (PFC) are evolving. The New York Pararescue Team has used part task training, cadaver labs, clinical rotations, and a complicated sim lab to prepare for PFC missions including critical care. This report details an Atlantic Ocean nighttime parachute insertion to provide advanced burn care to two sailors with 50% and 60% body surface area burns. Medical mission planning included pack-out of ventilators, video laryngoscopes, medications, and 50 L of lactated Ringer's (LR). Over the course of 37 hours, the patients required high-volume resuscitation, analgesia, wound care, escharotomies, advanced airway and ventilator management, continuous sedation, telemedicine consultation, and complicated patient movement during evacuation. A debrief survey was obtained from the Operators highlighting recommendation for more clinical rotations and labs, missionspecific pack-outs, and tactical adjustments. This historic mission represents the most sophisticated PFC ever performed by PJs and serves to validate and share our approach to PFC.
