Abstract

BACKGROUND/OBJECTIVE:In spring 2020, high numbers of children presented with acral pernio-like skin rashes, concurrent with the coronavirus disease 2019 (COVID-19) pandemic. Understanding their clinical characteristics/ infection status may provide prognostic information and facilitate decisions about management. METHODS:A pediatric-specific dermatology registry was created by the Pediatric Dermatology COVID-19 Response Task Force of the Society for Pediatric Dermatology (SPD) and Pediatric Dermatology Research Alliance (PeDRA) and was managed by Children's Hospital of Philadelphia using REDCap. RESULTS:Data from 378 children 0-18 years entered into the registry between April 13 and July 17, 2020 were analyzed. Data were drawn from a standardized questionnaire completed by clinicians which asked for demographics, description of acral lesions, symptoms before and after acral changes, COVID-19 positive contacts, treatment, duration of skin changes, laboratory testing including SARS-CoV-2 PCR and antibody testing, as well as histopathology. 229 (60.6%) were male with mean age of 13.0 years (± 3.6 years). Six (1.6%) tested positive for SARS-CoV-2. Pedal lesions (often with pruritus and/or pain) were present in 96%. 30% (114/378) had COVID-19 symptoms during the 30 days prior to presentation. Most (69%) had no other symptoms and an uneventful course with complete recovery. CONCLUSIONS AND RELEVANCE:Children with acral pernio-like changes were healthy and all recovered with no short-term sequelae. We believe these acral changes are not just a temporal epiphenomenon of shelter in place during the spring months of the first wave of the COVID-19 pandemic and may be a late phase reaction that needs further study.

摘要

背景/目的: 2020春季,大量儿童出现肢端状皮疹,并发冠状病毒疾病2019 (新型冠状病毒肺炎) 大流行。了解他们的临床特征/感染状态可以提供预后信息,并促进关于管理的决策。 方法: 由儿科皮肤病学会 (SPD) 和儿科皮肤病研究联盟 (PeDRA) 的儿科皮肤病学新型冠状病毒肺炎响应工作组创建了儿科特异性皮肤病注册,并由费城儿童医院使用REDCap管理。 结果: 分析了378名0-18岁儿童在2020年4月13日至7月17日期间进入登记的数据。数据来自由临床医生填写的标准化问卷,该问卷要求人口统计学、肢端病变描述、肢端变化前后的症状、新型冠状病毒肺炎例阳性接触者、治疗、皮肤变化持续时间、实验室检测 (包括SARS-CoV-2 PCR和抗体检测) 以及组织病理学。229 (60.6%) 为男性,平均年龄13.0岁 (± 3.6岁)。六名 (1.6%) 的SARS-CoV-2检测呈阳性。96% 存在踏板病变 (通常伴有瘙痒和/或疼痛)。30% (114/378) 患者在就诊前30天内出现新型冠状病毒肺炎症状。大多数 (69%) 无其他症状,病程平稳,完全康复。 结论和相关性: 肢端样改变的儿童健康,全部康复,无短期后遗症。我们认为这些肢端变化不仅仅是在新型冠状病毒肺炎大流行第一波的春季几个月期间出现的暂时掩体现象,可能是需要进一步研究的晚期反应。

METHODS::The ATP binding-cassette superfamily corresponds the mostly transmembrane transporters family found in humans. These proteins actively transport endogenous and exogenous substrates through biological membranes in body tissues, so they have an important role in the regulation of many physiological functions necessary for human homeostasis, as well as in response regulation to several pharmacological substrates. The development of multidrug resistance has become one of the main troubles in conventional chemotherapy in different illnesses including cancer, being the increased efflux of antineoplastic drugs the main reason for this multidrug resistance, with a key role of the ABC superfamily. Likely, the interindividual variability in the pharmacological response among patients is well known, and may be due to intrinsically factors of the disease, genetic and environmental ones. Thus, the understanding of this variability, especially the genetic variability associated with the efficacy and toxicity of drugs, can provide a safer and more effective pharmacological treatment, so ABC genes are considered as important regulators due to their relationship with the reduction in pharmacological response. In this review, updated information about transporters belonging to this superfamily was collected, the possible role of these transporters in cancer, the role of genetic variability in their genes, as well as some therapeutic tools that have been tried to raise against main transporters associated with chemoresistance in cancer.

METHODS:BACKGROUND:Cholinergic neurotransmission regulates neuroinflammation in Parkinson disease (PD). RESEARCH DESIGN AND METHODS:The authors conducted a delayed-start study of donepezil for cognitive decline in non-demented PD patients. The study consisted of a 96-week randomized placebo-controlled double-blind phase 1, followed by a 24-week donepezil extension phase 2. The primary outcome measure was a change in the Mini-Mental State Examination (MMSE) at week 120. RESULTS:A total of 98 patients were randomly allocated to the early-start (donepezil-to-donepezil) and delayed-start (placebo-to-donepezil) groups. Mean (SD) of the baseline MMSE was 27.6 (2.0) and 28.0 (2.1), respectively. MMSE change at week 120 was better in the early-start group than in the delayed-start group, but the difference was not significant. The MMSE declined in apolipoprotein ε4 carriers, but not in non-carriers, and the factor interaction (intervention × ε4 genotype) was highly significant (P < 0.001). Analyzed with the interaction, the difference was significant (group difference 1.95 [0.33 to 3.57], P = 0.018). The MMSE decline slope in phase 1 was significantly better in the early-start group than in the delayed-start group (P = 0.048). CONCLUSIONS:Cognitive function deteriorated in ε4 carriers, but not in non-carriers, and early-start donepezil may postpone cognitive decline in the former.

METHODS::Since the discovery of dental pulp stem cells, a lot of teams have expressed an interest in dental pulp regeneration. Many approaches, experimental models and biological explorations have been developed, each including the use of stem cells and scaffolds with the final goal being clinical application in humans. In this review, the authors' objective was to compare the experimental models and strategies used for the development of biomaterials for tissue engineering of dental pulp with stem cells. Electronic queries were conducted on PubMed using the following terms: pulp regeneration, scaffold, stem cells, tissue engineering and biomaterial. The extracted data included the following information: the strategy envisaged, the type of stem cells, the experimental models, the exploration or analysis methods, the cytotoxicity or viability or proliferation cellular tests, the tests of scaffold antibacterial properties and take into account the vascularization of the regenerated dental pulp. From the 71 selected articles, 59% focused on the "cell-transplantation" strategy, 82% used in vitro experimentation, 58% in vivo animal models and only one described an in vivo in situ human clinical study. 87% used dental pulp stem cells. A majority of the studies reported histology (75%) and immunohistochemistry explorations (66%). 73% mentioned the use of cytotoxicity, proliferation or viability tests. 48% took vascularization into account but only 6% studied the antibacterial properties of the scaffolds. This article gives an overview of the methods used to regenerate dental pulp from stem cells and should help researchers create the best development strategies for research in this field.
