or black seed is used as a medicinal plant around the globe. Oil and seeds have a long tradition of folklore use in various medicinal and food systems. The conventional therapeutic use of in different ways, has been reported in several studies to treat different diseases including influenza, headache, hypertension, diabetes, inflammation, eczema, fever, cough, asthma, bronchitis, and fever. Based on previously reported potential therapeutic uses of compounds, and keeping in mind the dire need of time for the development of potent antiviral, a combined docking, ADMET properties calculation, molecular dynamics, and MM-PBSA approaches were applied in the current study to check the therapeutic potentials of chief constituents against COVID-19. Among the studied compounds, we found that dithymoquinone (DTQ), with binding affinity of -8.6 kcal/mol compared to a positive control (chloroquine, -7.2 kcal/mol) , has the high potential of binding at SARS-CoV-2:ACE2 interface and thus could be predicted a plausible inhibitor to disrupt viral-host interactions. Molecular dynamics simulation of 100 ns well complemented binding affinity of the compound and revealed strong stability of DTQ at the docked site. Additionally, MM-PBSA also affirms the docking results. Compound DTQ of the present study, if validated in wet lab experiments, could be used to treat COVID-19 and could serve as a lead in the future for development of more effective natural antivirals against COVID-19.

Disparity in the testing rate of SARS-CoV-2 amongst different countries and regions is a very big challenge in understanding the COVID-19 pandemic. Although some developed countries have a very high testing rate and subsequently a high number of confirmed cases, less developed countries have a low testing rate and an illusive positivity rate. Collection of the upper respiratory specimen is not often comfortable. The discomfort could be accompanied with epistaxis and headache in some patients. The trained personnel taking the swab is forced to protect self with personal protective equipment (PPE) to avoid infections that may result from the patient due to provoked cough, sneezing and spitting. This study looks into an efficient means of increasing the testing rate for COVID 19 without compromising the quality. A literature review was conducted on the different modalities of collecting upper respiratory specimens and assessing the efficacy of samples collected using different methods in terms of the laboratory yield of different pathogens. Self-collection of upper respiratory tract specimen for diagnostic purposes is not new. Studies have demonstrated that trained staff-collected nasal swabs are not in any way superior to self-collected or parent-assisted swabs. The laboratory yield of different specimens is not determined by who took the sample but by the anatomical site from where the specimen was collected. Self collection of the upper respiratory swabs will not only increase the testing rate but also preserve the scarce PPE and reduces health care worker's COVID 19 infection rate in South Africa.

Sickle cell disease (SCD) is a genetic chronic haemolytic and pro-inflammatory disorder. With increased catabolism and deficits in energy and nutrient intake, individuals with SCD suffer multiple macro- and micro-nutritional deficiencies, including vitamin D deficiency. This is an update of a previous review.

Attempts to identify opioid users with increased risk of escalating to opioid use disorder (OUD) have had limited success. Retrospectively assessed subjective effects of initial opioid misuse were compared in a pilot sample of opioid misusers (nonmedical use ≤60 times lifetime) who had never met criteria for OUD (N = 14) and heroin-addicted individuals in treatment for OUD (N = 15). Relative to opioid misusers without a lifetime OUD diagnosis, individuals with OUD reported greater euphoria and other positive emotions, activation, pruritus, and internalizing symptoms. Consistent with these findings, proxy Addiction Research Center Inventory (ARCI) Amphetamine Group, and Morphine Benzedrine Group scale mean item scores were significantly higher in those with OUD. Replication was attempted in opioid misusers with (N = 25) and without OUD (N = 25) who were assessed as part of an ongoing genetic study. We observed similar significant between-group differences in individual subjective effect items and ARCI scale mean item scores in the replication sample. We, thus confirm findings from prior reports that retrospectively assessed subjective responses to initial opioid exposure differ significantly between opioid users who do, and do not, progress to OUD. Our report extends these findings in comparisons limited to opioid misusers. Additional research will be necessary to examine prospectively whether the assessment of subjective effects after initial use has predictive utility in the identification of individuals more likely to progress to OUD.

Chronic neuropathic pain is a common complication in people with spinal cord injury (SCI) but has not been investigated in dogs.

The growing prevalence of spinal pain in the USA continues to produce substantial economic impact and strain on health-related quality of life. Percutaneous adhesiolysis is utilized for recalcitrant, resistant conditions involving spinal pain when epidural injections have failed to provide adequate improvement, especially low back and lower extremity pain, specifically in post-lumbar surgery syndrome. Despite multiple publications and systematic reviews, the debate continues in reference to effectiveness, safety, appropriate utilization, and medical necessity of percutaneous adhesiolysis in chronic pain. This systematic review, therefore, was undertaken to evaluate and to update effectiveness of percutaneous adhesiolysis to treat chronic refractory low back and lower extremity pain, post-surgical patients of the lumbar spine.

There is a global concern of increasing number of children presenting with inflammatory syndrome with clinical features simulating Kawasaki disease, during ongoing COVID-19 pandemic. The authors report a very similar case of 5-y-old boy from a COVID-19 hotspot area who presented in late April 2020 with acute febrile illness with abdominal pain and loose stools followed by shock. On examination, child had bulbar conjunctivitis and extremity edema. Initial investigations showed high inflammatory parameters, elevated serum creatinine and liver enzymes. Echocardiography showed moderate LV dysfunction and normal coronaries. Cardiac enzymes were also elevated, suggesting myocarditis. He was treated with inotropic support, respiratory support with high flow nasal cannula, IV immunoglobulins, aspirin, steroids and diuretics. RT PCR for SARS-CoV-2 was negative twice. His clinical condition improved rapidly, was afebrile from day 2, inflammatory parameters decreased, left ventricular function improved and was discharged after 6 d of hospital stay.

The early detection of psoriatic arthritis (PSA) poses a challenge to rheumatologists, even when their diagnosis is aided by sonography. In order to facilitate early detection of PSA among patients with psoriasis (PSO), we retrospectively analyzed of the relationships between serological markers and comorbidities in 629 psoriatic patients, 102 of which had PSA, while the other 527 had PSO.

BACKGROUND The pathogenesis of sporadic multiple meningiomas in the patients without history of neurofibromatosis type II remains unclear. We report whole exome sequencing (WES) of 2 metachronous multiple meningiomas of the same patient. CASE REPORT A 39-year-old female had a 5-month history of headache and her magnetic resonance imaging (MRI) revealed a significantly enhanced intracranial space-occupying pathology with dura tail sign and skull invasion. She had no history of neurofibromatosis type II or other tumors. Tumor resection achieved Simpson grade I and the pathological studies revealed an atypical meningioma. After surgery, she accepted focal external-beam radiation therapy. One year later, MRI showed a significantly enhanced intracranial space-occupying pathology near the primary site of the previous tumor. She had only a mild headache. Simpson grade I resection of the tumor was achieved. The pathological diagnosis was still an atypical meningioma. WES on both tumors identified 220 common somatic gene mutations and 43 different somatic gene mutations. Three deleterious mutated genes including QRICH2, KIF2C, and MUC16 were identified only in the first tumor, and 9 deleterious mutated genes including FCGBP, RPS6KA5, GOLGA6L2, IGHV3-66, RPTN, AGRN, USP6, CLTCL1, and PABPC3 were identified only in the second tumor. As shown by the identical result of 3 prediction tools, RPS6KA5 and AGRN were most likely to be related to the progress of multiple atypical meningiomas. CONCLUSIONS The metachronous meningiomas with same World Health Organization (WHO) grades in the same patient could have distinct genetic aberration patterns. The roles of RPS6KA5 and AGRN in the rapid progress of multiple atypical meningiomas need further studies.

Chronic pruritus is a symptom of many systemic diseases. In contrast to dermatological pruritus, there are no primary changes in skin appearance. Establishing the correct diagnosis in these cases can be quite challenging. In some instances, laboratory tests can be helpful. This report highlights the importance of specific and target-orientated laboratory tests in four patients with chronic pruritus due to systemic diseases.
