In pediatric patients, severe cutaneous adverse reactions (SCARs) frequently occur in the course of acute illnesses, mostly infections, which are usually treated with antibiotics or analgesics. The drug provocation test (DPT) is contraindicated in such situations, due to the risk of triggering a new severe reaction. As a consequence, lifelong avoidance is recommended. However, causation is uncertain in most cases. The dilemma arises when avoiding the drug is not harmless for the patient. We have attended three patients who were referred to our pediatric allergy unit with a history of SCAR related in time to simultaneous use of paracetamol and ibuprofen. Medical records and images of the patients were reviewed with the assistance of a dermatologist, and alternative diagnoses were considered in both cases. The ALDEN score for implicated drugs was calculated. After considering a high probability of ibuprofen tolerance and obtaining informed consent from the patients, we performed a sequential allergy workup including in vitro tests, skin tests, and finally DPT in two of the patients, confirming ibuprofen tolerance. In conclusion, although generally contraindicated, DPT may be considered for some useful drugs after careful evaluation of the risk-benefit balance, preceded by a sequential study including in vitro and skin tests.

The novel disease caused by the new coronavirus SARS-CoV-2 has caused an unprecedented global pandemic. Care providers of asthmatic children are increasingly con-cerned; as viral infections are one of the primary triggers of asthma flare-up. However, the effect of SARS-CoV-2 as well as the generated worldwide lockdown on asthmatic children is unknown.

The aim of this study was to analyze the effects of pandemic SARS-CoV-2 in pediat-ric asthma control.

A retrospective, open, transversal study was performed at five ter-tiary hospitals. Recruited patients were aged <18 years and had physician-diagnosed asthma. Information regarding the 2019 and 2020 seasons were provided.

Data were collected from 107 children (age range 3-18 years, mean age 12 years). Well-controlled asthma was observed in 58 (54.2%) patients in 2020 versus 30 (28%) in 2019, and 15 (14%) patients had poorly controlled asthma in 2020 versus 28 (26.2%) in 2019. In 2020, a decrease in exacerbations caused by allergies to pollen, dust mites, molds, and through other causes not related to SARS-CoV-2 infection was observed. An increase in exacerbations was observed due to animal dander, stress, physical exercise, and SARSCoV-2 infection. Children had a reduced need for asthma-controlling medication, made fewer visits to healthcare providers and had lesser need of treatment with oral corticosteroids if compared with the same season of 2019.

Pediatric asthma control improved, the need for controller medication declined, and fewer visits to healthcare providers were made during the pandemic if compared with the 2019 season.

Asthma is a common chronic inflammatory disease of the airway, and airway remodeling and the proliferation mechanism of airway smooth muscle cells (ASMCs) is of great significance to combat this disease.

To assess possible effects of scopoletin on asthma and the potential signaling pathway.

ASMCs were treated PDGF-BB and scopoletin and subjected to cell viability detection by CCK-8 assay. Cell migration of ASMCs was determined by a wound closure assay and transwell assay. The protein level of MMP2, MMP9, calponin and α-SMA were measured using western blot. The levels of NF-κB signaling pathway were detected by Western blotting.

Scopoletin inhibited proliferation of PDGF-BB - induced ASMCs. Also it suppressed the migration and invasion of PDGF-BB - induced ASMCs. We further showed that Scopoletin regulated phenotypic transition of ASMCs. Mechanically, Scopoletin inhibited proliferation and invasion of ASMCs by regulating NF-κB signaling pathway.

We therefore thought Scopoletin could serve as a promising drug for the treatment of asthma.

There is insufficient clarity regarding whether or not drugs used in asthma cause behavioral problems in children.

A total of 155 individuals, categorized into an asthma group (n = 95) and a control group (n = 60), were enrolled in the current prospective controlled study. The asthma group consisted of patients receiving treatment (inhaled corticosteroids [ICS] or montelukast) for at least 1 month. Check Behavior Checklist (CBCL) for ages 1.5-5 scores for the asthma and controls were compared. The asthma group was divided into two subgroups based on prophylactic therapy received, ICS and montelukast, and these groups' CBCL scores were also compared.

The asthma group consisted of 95 children (ICS subgroup 45, montelukast subgroup 50) and the healthy control group of 60 cases. The mean total CBCL score was higher in the asthma group than in the control group (42 vs 32, respectively, P = 0.001). selleck products Internalization and externalization scores were also higher in the asthma group compared to the control group (P should be kept in mind that montelukast may cause serious neuropsychiatric events such as hallucination.

This study envisages understanding about the Oral Health-Related Quality of Life (OHRQoL) among groups of foundling and delinquent children and compares them with mainstream children in Riyadh, Saudi Arabia.

This is a cross-sectional, observational study of a group of foundling and delinquent children aged 11 to 14 years, in care houses in Riyadh, Saudi Arabia, and mainstream school children. Variables measured for each group were demographic data (age, gender), subjective oral health condition, and OHRQoL. An interview-based questionnaire was used for collecting the relevant data. The questionnaire was divided into four parts, oral symptoms, functional limitations, emotional well-being, and social well-being, with each response scored as per the following codes (0) never, (1) once or twice, (2) sometimes, (3) often, and (4) every day. The top possible score for the total scale was 144, and the lowest was 0. A comparison group of mainstream school children was recruited from public schools. Data were analvely new, delinquents and foundling are definitely subjected to poorer standards in terms of their oral hygiene, on-time treatment, and diagnosis, which further deteriorates their quality of life.

Health, including oral health, is a right everyone is equally subjected to, and while the concept of OHRQoL is relatively new, delinquents and foundling are definitely subjected to poorer standards in terms of their oral hygiene, on-time treatment, and diagnosis, which further deteriorates their quality of life.Knee osteoarthritis-associated bone marrow edema-like lesions (KOA-BMLs) is a common MRI imaging feature, which is mainly manifested as abnormal bone marrow hyperintensity in subchondral bone on T2 imaging. The formation of KOA-BMLs may be related to the abnormality of lower limb force line and subchondral bone perfusion, and related histopathological studies showed that the remodeling of bone and bone marrow in these damaged areas was abnormally increased. In KOA patients, the size of BMLs can fluctuate or even disappear in a relatively short period of time, and was closely related to pain, subchondral bone cyst formation, and the progression of KOA. However, the current treatment methods for KOA-BMLs are limited, and there is no uniform guideline or expert consensus, mainly includingmedication, physical therapy and surgical treatment. This article reviews the research progress of the disease characteristics and treatment of KOA-BMLs in order to provide guidance for the clinical diagnosis and treatment of KOA-BMLs.

To evaluate the clinical efficacy of local infiltration anesthesia of ropivacaine combined with compound betamethasone for postoperative analgesia in patients with hallux valgus.

From September 2019 to December 2020, 48 patients with hallux valgus were treated surgically. According to different postoperative analgesia methods, the patients were divided into combined local infiltration group and intravenous analgesia pump group. There were 24 cases, in the combined local infiltration group including 2 males and 22 females;the age ranged from 21 to 78 years old, with an average of (58.3±7.7) years old;soft tissue release and chevron osteotomy were performed in 15 cases and metatarsophalangeal joint fusion in 9 cases;immediately after operation, 20 ml of ropivacaine combined with compound betamethasone mixed diluent was used for local infiltration anesthesia once. There were 24 patients in intravenous analgesia pump group, including 3 males and 21 females;the age ranged from 23 to 81 years old, with an averaifference in the number of adverse drug reactions between the two groups at 0 to 12 hours after operation (

>0.05);there was significant difference in the number of adverse drug reactions 12 to 24 hours after operation (

<0.05). No adverse drug reactions occurred in both groups 24 to 48 hours after operation. There was no significant difference in the grade of knife edge healing between the two groups after suture removal (

>0.05).

Compared with intravenous analgesia pump group, ropivacaine combined with compound betamethasone can significantly reduce postoperative wound pain without increasing adverse drug reactions, and does not increase wound infection.

To investigate the effect of the exosomes from bone marrow mesenchymal stem cells (BMSCs) transfected with silence plasmid of Piezol small interference RNA (siRNA)on osteoarthritis (OA) animal model.

Twenty male SD rats with specific pathogen free (SPF) were selected, ranging in age from 5.46 to 6.96 months, with a mean of (6.21± 0.75) months;and ranging in weight from 385.76 g to 428.66 g, with a mean of (407.21±21.45) g. BMSCs were extracted. The siRNA silencing plasmid of piezo1 was constructed by siRNA technology. After lentivirus was transfected into BMSCs, the exosomes were extracted. At the cellular level, BMSCs were divided into blank plasmid group and siRNA silencing plasmid group according to whether siRNA-Piezo1 was transfected or not. The osteogenic induction ability of siRNA-Piezo1 on BMSCs was detected by RT-PCR and Western blot. At the animal model level, the OA model was established by surgical resection of cruciate ligament of knee joint.According to different treatment schemes, SD rats w group (

< 0.05), and the relative expression of aggrecan mRNA in exosome group was higher than that in BMSCs group and model group (

<0.05). The relative expression of CollagenⅡmRNA in BMSCs group was higher than that in model group (

<0.05), and the relative expression of CollagenⅡmRNA in exosomes group was higher than that in BMSCs group and model group (

<0.05).

Piezo1 siRNA silencing vector can promote the differentiation of BMSCs into chondrocytes and effectively inhibit the progression of OA, so as to delay the disease of OA.
