In the present study, we investigated whether magnesium sulphate activates the L-arginine/NO/cGMP pathway and elicits peripheral antinociception. The male Swiss mice paw pressure test was performed with hyperalgesia induced by intraplantar injection of prostaglandin E2. All drugs were administered locally into the right hind paw of animals. Magnesium sulphate (20, 40, 80 and 160 μg/paw) induced an antinociceptive effect. The dose of 80 μg/paw elicited a local antinociceptive effect that was antagonized by the non-selective NOS inhibitor, L-NOArg, and by the selective neuronal NOS inhibitor, L-NPA. The inhibitors, L-NIO and L-NIL, selectively inhibited endothelial and inducible NOS, respectively, but were ineffective regarding peripheral magnesium sulphate injection. The soluble guanylyl cyclase inhibitor, ODQ, blocked the action of magnesium sulphate, and the cGMP-phosphodiesterase inhibitor, zaprinast, enhanced the antinociceptive effects of intermediate dose of magnesium sulphate. Our results suggest that magnesium sulphate stimulates the NO/cGMP pathway via neuronal NO synthase to induce peripheral antinociceptive effects.

Patients with chronic pain syndromes are facing additional challenges from syndrome coronavirus 2 (SARS-CoV-2) virus compared with the general population. New reasons for compounded social isolation and commensurate opioid dose creeping and suicidality/anxiety, difficulty in obtaining legitimate medications, proper comprehensive evaluations, ongoing opioid risk stratification for opioid abuse/misuse, safe opioid tapers if necessary, and other opportunities for pharmacist intervention are clear. We discuss opportunities for pharmacist-run telehealth visits, reimbursement for services, and various aspects of interventions during this time of international emergency where all healthcare professionals have been asked to step up to help combat the mutual threat of COVID19. Clinical pharmacists in every specialty area are part of the essential healthcare workforce, but those practicing pain management in particular are in unique positions to assist all providers in adhering to chronic pain guidelines and various government mandates, and to foster optimal outcomes to complex patients with chronic pain. Furthermore, those that are available by telemedicine allow for improved access to quality and appropriate pain medication management, and additionally support opioid risk mitigation strategies, helping fill an unmet access to those at higher risk. This practice has the potential to help offset primary care provider workload, allowing for a decreased overall burden, especially in a complex, time-consuming, and high-risk patient population.

The Chronic Pain Self-Management Program is an evidence-based intervention that has been shown to be efficacious in reducing symptoms of chronic pain. However, there is a paucity of research examining CPSMP in a predominantly rural population. The purpose was to evaluate patient-reported outcomes of in-person peer-led CPSMP workshops offered in a rural region in 2018 and 2019.

Optimal analgesic maintenance for severe cancer pain is unknown. This study evaluated the efficacy and safety of intravenous patient-controlled analgesia (IPCA) with continuous infusion plus rescue dose or bolus-only dose versus conventional oral extended-release morphine as a background dose with normal-release morphine as a rescue dose to maintain analgesia in patients with severe cancer pain after successful opioid titration.

A 49-year-old woman with no inflammatory bowel disease history presented to our clinic with abnormal liver function tests and right upper quadrant abdominal pain. Blood tests revealed a mixed pattern of liver injury. Abdominal magnetic resonance imaging demonstrated hepatomegaly with periportal edema and hyper-enhancing bile ducts without any sign of biliary obstruction or stricturing. Screening for viral hepatitis and autoimmune liver diseases was negative. An elevated immunoglobulin G (IgG) level suggested the possibility of autoimmune hepatitis (AIH), and a biopsy confirmed the presence of severe interface hepatitis with necrotic areas and focal lymphoid nodular formation. IgG4 staining revealed marked IgG4-positive plasma cell infiltration. A diagnosis of IgG4-associated seronegative AIH was made, and the patient was started on prednisone and azathioprine, with rapid resolution of the enzyme abnormalities. This clinical vignette highlights the potential challenges in establishing a diagnosis of IgG4-associated AIH and cholangitis, as demonstrated by the importance of confirmatory histopathology. Clinicians should maintain a high index of suspicion when confronted with a mixed pattern of liver injury with elevated immunoglobulins but seronegative autoimmune markers.

Pituitary corticotroph macroadenomas, which account for 7% to 23% of corticotroph adenomas, rarely present with apoplexy. This report aimed to describe a patient with a sparsely granulated corticotroph tumor (SGCT) presenting with apoplexy and remission of hypercortisolism.

Perimenopause is linked to increased migraine (Mg), especially menstrual Mg (MMg), influenced by hormonal changes. Compared to nonmenstrual attacks, menstrual attacks are more disabling and less responsive to treatment. Women with perimenstrual estrogen withdrawal have been linked to Mg during menstruation, whereas Mg during perimenopause has been linked to unpredictable fluctuations in estrogen levels. It has been widely established that female sex hormones play a role in Mg, but how it occurs remains unclear. This narrative review was identified using Medline and PubMed searches between 1946 and 2021. Search terms included "headache," "migraine," "menstrual migraine," "menstruation," "menopause," "perimenopause," "estrogen," and "progesterone." This article focuses on the candidate genes and female hormones that play a role in MMg. More study is necessary to understand better the environmental components that play a critical role in disease development. Currently, there is insufficient clinical evidence to support the function of menstrual Mg. The specific research facts examined MMg unique candidate genes and female hormonal factors that support their association and found MMg etiologic processes for generating an early diagnostic marker.

Prior to the COVID-19 pandemic, about half of patients from populations that sought care in neurology tried complementary and integrative therapies (CITs). With the increased utilization of telehealth services, we sought to determine whether patients also increased their use of virtual CITs.

Drug information can be obtained from various drug information sources that were available as government (National Formulary of India [NFI]; Central Drugs Standard Control Organization [CDSCO]), as well as commercial documents (Current Index of Medical Specialties [CIMS] and Monthly Index of Medical Specialties [MIMS]). Irrational drug usage may happen due to wide variation in the information available in these sources. In this study, we tried to assess these variations in a sample of drugs for the acute-specific management of migraine with ergot and Triptans antimigraine drugs in drug information sources such as NFI, CIMS, MIMS, and CDSCO. Scoring was done for various drug information based on the completeness of information about drugs used in acute-specific management of migraine. The scores for the completeness of drug information about the selected antimigraine drugs are 18.37% for CIMS (Ergotamine, Sumatriptan, Rizatriptan, and Zolmitriptan), 21.1% for NFI (Dihydroergotamine, Sumatriptan), 72.79% for MIMS (Ergotamine tartrate, Sumatriptan, Rizatriptan, Naratriptan, zolmitriptan, Almotriptan) and 21.77% for CDSCO (Ergotamine tartrate, Sumatriptan, Rizatriptan, Naratriptan, Zolmitriptan, eletriptan and almotriptan). The information for the antimigraine drugs available from various sources found to so much deficient. Necessary steps need to be taken in case of government public or hard documents to streamline drug information available with them as well the commercial documents as to provide reliable drug information uniformly for promoting rational use of the drug.

Vasculopathy is a crucial feature of systemic sclerosis (SSc). It occurs in almost every patient with SSc, with Raynaud's phenomenon (RP) and digital ulcers (DU) having a great impact on the quality of patients' lives. Intravenous (IV) iloprost, a synthetic analogue of prostacyclin, is broadly used to treat RP and DU secondary to SSc. Currently, there is no standard protocol defined for the iloprost treatment of SSc-associated RP and DU, and, consequently, the management of this treatment is largely based on each centre's experience.
