Most patients with COVID-19 have mild or moderate manifestations, however, there is a wide spectrum of clinical presentations and even more severe repercussions that require high diagnostic suspicion. Vital sign acquisition and monitoring are crucial for detecting and responding to patients with COVID-19.

Aim To determine if a single pre-operative dose of oral corticosteroids would be effective in reducing pain, trismus and oedema following lower third molar surgical extraction. Secondary outcomes of interest were post-operative complications such as infections.Methods Searching was conducted using Embase, Medline, DOSS, CINAHL and CENTRAL for randomised controlled trials. Four studies which compared pre-operative oral corticosteroids to placebo before lower third molar surgical extractions were eligible for inclusion.Results All studies were judged to be at unclear risk of bias. All studies tested the efficacy of 8 mg dexamethasone 60-90 minutes before surgical extractions. While three studies showed improvement in pain visual analogue scale (VAS) scores in the dexamethasone groups, two were not statistically significant. One study found no improvement in pain scores on VAS. One study found no difference in either trismus or oedema. One study reported one occurrence of post-operative alveolar infection in the dexamethasone group and one occurrence of alveolar osteitis in the placebo group.Conclusion While there seems to be an improvement in pain scores on VAS, these results are not clinically significant. Post-operative analgesia plays a more important role clinically.

Aconitine is a natural toxic substance belonging to the family of aconitum alkaloids, which is used in small doses by Traditional Chinese practitioners. We present a case of accidental death due to acute aconitine poisoning. A 65-year-old Chinese man presented to a medical clinic with fever and shoulder pain. Soon after administration of intravenous ceftriaxone, a bottle of Chinese medicinal wine was administered. The man rapidly experienced headache, hearing loss and tinnitus, nausea, diarrhea, numbness of the lips, tongue, face, and the upper and lower extremities, cold sweat, fall of blood pressure, and discomfort of the entire body, and he died on the same day. Postmortem examination showed cyanosis of the nail beds, severe congestion in lungs and other organs, bilateral pleural effusions, and infiltration of basophils in the intestinal submucosa. No significant increase of IgE was found in the blood. Toxicological analysis detected aconitine in the medicinal wine, blood, and stomach contents by liquid chromatography-tandem mass spectrometry (LC-MS⁄MS). Aconitine was quantified in cardiac blood as 16.4 ng/ml, and in stomach contents (63.8 ng/ml) and wine sample (10.1 ug/ml). The cause of death was aconitine poisoning. This case report highlights the danger of aconitine. LC-MS⁄MS has the advantages of high analytic speed, sensitivity, and accuracy. It would be desirable for the government to control the use of aconitine-containing herbal extracts.

Underweight or overweight in adolescence is linked to several adverse health outcomes. Less evidence exists about the association between weight status and school-related psychosocial characteristics in high income countries. We sought to investigate the relationship between weight status and psychosomatic and school-related complaints with a focus on gender differences. The study is a cohort of 18,462 adolescents (12-19 years; 51% girls) conducted in Sweden. The associations between weight status and psychosomatic and school-related complaints were estimated by binary logistic regression adjusted for several potential confounders. After correction for multiple testing, being underweight or overweight/obese was adversely associated with several psychosomatic and school-related complaints with significant differences between boys and girls. Specifically, underweight boys had higher odds to have psychosomatic complaints than normal-weight boys, while no such associations were observed among underweight girls. Overweight/obese (vs. normal-weight) boys had higher odds to complain about headache, pain in the back/hips, and feeling low. Overweight/obese (vs. normal-weight) girls were more likely to complain about feeling low, anxious/worried and having difficulty in falling asleep (P ≤ 0.01). In relation to school-related complaints (e.g., being bullied at school and academic failure), greater associations were observed for overweight/obese girls and boys than for underweight adolescents compared with normal-weight peers.

Mesenchymal stem/stromal cell (MSC)-based therapies have been proposed for back pain and disc degeneration, despite limited knowledge on their mechanism of action. The impact of MSCs/their secretome on annulus fibrosus (AF) cells and tissue was analysed in bovine AF organ cultures (AF-OCs) exposed to upper-physiological cyclic tensile strain (CTS, 9 %, 1 Hz, 3 h/d) and interleukin (IL)-1β in a custom-made device. A 4 d treatment of the CTS + IL-1β-stimulated AF-OCs with MSC secretome downregulated the expression of inflammation markers [IL-6, IL-8, prostaglandin-endoperoxide synthase 2 (PTGS2)], complement system regulators [cluster of differentiation (CD)46, CD55, CD59] and matrix metalloproteinase 1 but also of tissue inhibitors of metalloproteinases (TIMP-1, TIMP-2) and collagen type I. At the protein level, it was confirmed that IL-6, MMP-3 and collagen content was decreased in AF-OCs treated with the MSC secretome compared to the CTS + IL-1β stimulation alone. 9 d after treatment, a biomechanical peel-force test showed that the annular adhesive strength was significantly decreased by the MSC secretome treatment. Overall, MSC secretome had a stronger impact on AF tissue than MSCs in co-culture. The secretome contributed to a decrease in the inflammatory and catabolic status of AF cells activated by CTS + IL-1β and played a role in the regulation of the complement system. However, it also contributed to a decrease in collagen at the gene/protein level and in AF mechanical strength compared to the CTS + IL-1β stimulation alone. Therefore, the use of MSC secretome requires further investigation regarding its influence on disc matrix properties.

Non-steroidal anti-inflammatory drugs (NSAID) have excellent anti-inflammatory and analgesic properties and are extensively used to treat post-traumatic or surgical musculoskeletal pain. Although an extensive literature exists on the administration of NSAID on animal bone healing, no systematic review and meta-analysis of animal studies that investigate the effect of NSAID administration on bone fracture healing. Objective of this study is to conduct a systematic review and meta-analysis to estimate the effect of NSAIDs administration on bone healing biomechanical and histomorphometric measurements in different animal models after bone fracture surgery.

Cholesterol granulomas are rare cystic inflammatory lesions characterized by the formation of cholesterol crystals. They are the most prevalent lesions of the petrous apex and when symptomatic, hearing loss, vertigo, tinnitus, headache, and facial pathology can be present. Surgical management is recommended in symptomatic patients. There are different surgical approaches to cholesterol granulomas. The aim of this article is to present and describe an endoscopic endonasal nasopharyngeal approach to a cholesterol granuloma and explain the advantages and disadvantages.

Sleep problems are common and may be associated with persistent pain. It is unclear whether non-pharmacological interventions improve sleep and pain in adults with comorbid sleep problems and musculoskeletal (MSK) pain. We conducted a systematic review on the effectiveness of non-pharmacological interventions on sleep characteristics among adults with MSK pain and comorbid sleep problems. We searched MEDLINE, EMBASE, CINAHL, Cochrane Central and PsycINFO from inception to April 2, 2021 for randomized controlled trials (RCTs), cohort, and case-control studies. Pairs of independent reviewers critically appraised and extracted data from eligible studies. We synthesized the findings qualitatively. We screened 8459 records and identified two RCTs (six articles, 467 participants). At 9 months, in adults with insomnia and osteoarthritis pain, cognitive behavioral therapy for pain and insomnia (CBT-PI) was effective at improving sleep (Insomnia Severity Index, ISI) when compared to education (OR 2.20, 95% CI 1.25, 3.90) or CBT for pain (CBT-P) (OR 3.21, 95% CI 1.22, 8.43). CBP-P vs. education was effective at increasing sleep efficiency (wrist actigraphy) in a subgroup of participants with severe pain at baseline (mean difference 5.45, 95% CI 1.56, 9.33). At 18 months, CBT-PI, CBT-P and education had similar effectiveness on sleep and pain or health outcomes. In adults with insomnia and knee osteoarthritis, CBT-I improved some sleep outcomes including sleep efficiency (diary) at 3 months (Cohen's d 0.39, 95% CI 0.24, 1.18), and self-reported sleep quality (ISI) at 6 months (Cohen's d - 0.62, 95% CI -1.01, - 0.07). The intervention was no better than placebo (behavioural desensitization) for improving other sleep outcomes related to sleep onset or pain outcomes. Short-term improvement in sleep was associated with pain reduction at 6 months (WOMAC pain subscale) (sensitivity 54.8%, specificity 81.4%). Overall, in two acceptable quality RCTs of adults with OA and comorbid insomnia, CBT-PI/I may improve some sleep outcomes in the short term, but not pain outcomes in the short or long-term. Clinically significant improvements in sleep in the short term may improve longer term pain outcomes. Further high-quality research is needed to evaluate other non-pharmacological interventions for people with comorbid sleep problems and a range of MSK conditions.

Cholangitis refers to inflammation of the bile ducts with or without accompanying infection. When intermittent or persistent inflammation lasts six months or more, the condition is classified as chronic cholangitis. Otherwise, it is considered an acute cholangitis. Cholangitis can also be classified according to the inciting agent, complete mechanical obstruction, which is the leading cause of acute cholangitis, longstanding partial mechanical blockage, or immune-mediated bile duct obliteration damage that results in chronic cholangitis.The work-up for cholangitis is based upon medical history, clinical presentation, and initial laboratory tests. Whereas ultrasound is the first-line imaging modality used to identify bile duct dilatation in patients with colicky abdominal pain, cross-sectional imaging is preferable when symptoms cannot be primarily localized to the hepatobiliary system. Computed tomography (CT) is very useful in oncologic, trauma, or postoperative patients. Otherwise, magnetic resonance cholangiopancreatography (MRCP) is the method of choice to diagnose acute and chronic biliary disorders, providing an excellent anatomic overview and, if gadoxetic acid is injected, simultaneously delivering morphological and functional information about the hepatobiliary system. If brush cytology, biopsy, assessment of the prepapillary common bile duct (CBD), stricture dilatation, or stenting is necessary, then endoscopic ultrasound (EUS) and/or retrograde cholangiography (ERC) are performed. Finally, when the pathologic duct is inaccessible from the duodenum or stomach, percutaneous transhepatic cholangiography (PTC) is an option. The pace of the work-up depends upon the severity of cholestasis on presentation. Whereas sepsis, hypotension, and/or Charcot's triad warrant immediate investigation and management, chronic cholestasis can be electively evaluated.This overview article will cover the common cholangitides, emphasizing our clinical experience with the chronic cholestatic liver diseases.

Ebola Virus Disease (EVD) is a deadly and feared infectious disease, which can be responsible of debilitating physical and psychological sequelae in survivors including depression and anxiety disorders. Unfortunately, there are scarce data on survivor sequelae in Democratic Republic of the Congo. So this study assessed PTSD, depression and anxiety symptoms among EVD survivors enrolled in the follow-up program of the psychosocial care team of Beni town's general hospital.
