Pectoral nNerve (PECS) block type-1 is an Ultrasound (US)-guided interfacial block that can be performed for postoperative analgesia management after breast surgery. In the procedure, a local anesthetic solution is injected into the interfacial area between the Pectoralis Major muscles (PMm) and Pectoralis minor muscles (Pmm). The present study compared PECS block type-1 administered preoperatively or postoperatively for postoperative analgesia after breast augmentation surgery.

Cleft palate is a common craniofacial malformation, requiring surgical repair in late infancy or early toddlerhood. Postoperative use of opioids is common to mitigate pain following palatoplasty. To decrease opioid consumption, improve postoperative pain, and decrease complications associated with general anesthetics, intraoperative regional nerve blocks have been employed for multimodal pain relief. While the literature supports intraoperative nerve block use for postprocedural comfort in children undergoing palatoplasty, the topic has not been systematically summarized.

In March 2020 -still the early days of the U.K.'s COVID-19 crisis-Rhys Thomas, a neurologist at Newcastle University, got a call at home from a concerned colleague. The colleague's cousin was hospitalized, critically ill with COVID-19, and had developed brainstem encephalitis, a severe inflammatory condition of the brain causing a suite of symptoms, from eye problems to balance problems and drowsiness. He wanted to know if Thomas knew anything about these conditions. At the time, the research coming out of Wuhan, China, only suggested a mild whiff of neurological symptoms-headache, dizziness, and the loss of taste and smell. Clearly the virus could affect the brain in some ways, but it wasn't, Thomas thought then, anything serious. But this report sounded much more concerning. Symptoms like this patient's would mean the virus was accessing more of the nervous system than scientists originally thought.

Delayed cerebral ischaemia (DCI) and cerebral infarction is a much-feared complication of aneurysmal subarachnoid haemorrhage (aSAH). It has been largely attributed to focal hypoperfusion from reversible cerebral arterial narrowing, "vasospasm," from the effects of prolonged exposure of the arteries to perivascular blood and oxy-haemoglobin. Transcranial Doppler (TCD) provides a non-invasive method for detecting and monitoring vasospasm. We report a 38-year-old lady who developed sudden dizziness and catastrophic generalised headache with neck pain (Pain Score 10/10) while voiding her bowels. She subsequently became drowsy and was brought to hospital. On examination, she was already alert and orientated. Blood pressure was 175/109 mm Hg. Her neurological examination was normal but for severe neck stiffness to passive flexion. Computed tomography of the brain showed extensive SAH. Cerebral angiography revealed a 6 × 3 mm aneurysm along the posteromedial aspect of the supraclinoid left internal carotid artery. She underwent aneurysm coiling that night. She was given intravenous and then oral nimodipine. TCD monitoring of the circle of Willis on day 14 detected very high velocities in the right and left middle cerebral arteries, mean velocity 187 and 141 cm/s, middle cerebral artery/internal carotid artery ratio 6.03 and 4.15, suggestive of severe and moderate vasospasm, respectively. She did not develop any related neurological symptoms or deficits. She was maintained in a euvolemic state and given high volumes of intravenous saline (2.4 L/day). Repeat TCD 7 days later was normal. The intravenous saline was gradually tailed off and she was subsequently discharged. TCD has an important role in the non-invasive detection and monitoring of vasospasm after aSAH.

In this study, we sought to elucidate the molecular mechanism underlying human Mas-related G protein-coupled receptor X1 (MrgprX1) mediated itch sensation. We found that activation of MrgprX1 by BAM8-22 triggered robust action potential discharges in dorsal root ganglion (DRG) neurons. This neuronal excitability is not mediated by Transient receptor potential (TRP) cation channels, M-type potassium channels, or chloride channels. Instead, activation of MrgprX1 lowers the activation threshold of TTX-resistant sodium channels and induces inward sodium currents. These MrgprX1-elicited action potential discharges can be blocked by Pertussis toxin (PTX) and a Gβγ inhibitor – Gallein. Behavioral results showed that Nav1.9 knockout but not Trpa1 knockout significantly reduced BAM8-22 evoked scratching behavior. Collectively, these data suggest that activation of MrgprX1 triggers itch sensation by increasing the activity of TTX-resistant voltage-gated sodium channels.

The low prevalence of erythromelalgia, classified as an orphan disease, poses diagnostic and therapeutic difficulties. The aim of this review is to be an update of the specialized bibliography. Erythromelalgia is an infrequent episodic acrosyndrome affecting mainly both lower limbs symmetrically with the classic triad of erythema, warmth and burning pain. Primary erythromelalgia is an autosomal dominant inherited disorder, while secondary is associated with myeloproliferative diseases, among others. In its etiopathogenesis, there are neural and vascular abnormalities that can be combined. The diagnosis is based on exhaustive clinical history and physical examination. Complications are due to changes in the skin barrier function, ischemia and compromise of cutaneous nerves. Because of the complexity of its pathogenesis, erythromelalgia should always be included in the differential diagnosis of conditions that cause chronic pain and/or peripheral edema. The prevention of crisis is based on a strict control of triggers and promotion of preventive measures. Since there is no specific and effective treatment, control should focus on the underlying disease. However, there are numerous topical and systemic therapies that patients can benefit from.

The pathologies of the musculoskeletal apparatus are the most common cause of chronic diseases, with a huge impact on people and society. Scientific literature has discovered how experiencing chronic pain directly affects peoples' well-being, lifestyle, social relationships and can also cause psychological distress. The present study aims to investigate pain experience in patients with hernias or protrusions of the cervical and lumbosacral tract on a sample of 120 patients, recruited from patients of Poliambulatorio Oberdan, medical centre in Brescia (Italy) specialized in physical rehabilitation and CT-guided oxygen ozone therapy. In a bio-psychosocial perspective, the research aimed to investigate how the perception of pain, the mood state associated with it, the coping strategies adopted and the quality of life differ according to each patient's gender and to the more or less prolonged use of pain medication. The data were collected by means of medical and psychological anamnestic interviews and self-report tests (WHOQOL-BREF, COPE-NVI, POMS). The quantitative analysis, carried out through SPSS 25 (2017) software, showed how functional impairment of one's autonomy (walking, driving) affects mood states. In particular, the female sample expressed a more deflected mood, despite the greater use of relational and/or transcendent support (coping strategies) compared to men. The study suggests that the greater impairment of the moods of women can be attributed both to the caregiving role they play, which often results in a greater fatigue and difficulties in redefining this role following the algic condition, and more general differences in the expression of suffering, which, on a cultural level, sees men emotionally coerced. The analysis also shows how taking pain medication for a long period of time has a negative impact on the quality of life. The results suggest that the patients treated with analgesic therapy tend to adopt avoidant coping styles, which usually escalate into postponement of the time when dealing with a stressful situation and, if used in the long run, may lead to worsening health condition.

The United States (US) military utilizes combat wound medication packs (CWMP) to provide analgesia and wound prophylaxis in casualties who are still able to fight. We compared characteristics of combat casualties receiving CWMP to those not receiving CWMP. We also describe the proportions of casualties with injury patterns consistent with Tactical Combat Casualty Care (TCCC) guideline indications for CWMP use who received this intervention.

Enhanced recovery after surgery (ERAS) aims to achieve earlier recovery, reduced hospital length of stay (LOS) and improved outcomes. Following the introduction of our ERAS protocol, we sought to review our ERAS experience. Our aims were to evaluate the LOS, post-operative complications, discharge analgesia, patient satisfaction and our ERAS protocol compared to the literature.

Coronavirus disease-19 (COVID-19) pandemic continues to grow all over the world. Several studies have been performed, focusing on understanding the acute respiratory syndrome and treatment strategies. However, there is growing evidence indicating neurological manifestations occur in patients with COVID-19. Similarly, the other coronaviruses (CoV) epidemics; severe acute respiratory syndrome (SARS-CoV-1) and Middle East respiratory syndrome (MERS-CoV) have been associated with neurological complications.
