Palmar Purpura: An Atypical Presentation of Childhood Dermatitis Herpetiformis

Abstract: Dermatitis herpetiformis (DH) is seen most commonly as a pruritic, papulovesicular eruption in young children or adolescents. Differentiation from other bullous diseases of childhood may be difficult. We report the first case of an adolescent in whom pruritic, palmar, purpuric macules and papules were the only manifestations of DH. The patient later developed typical vesiculobullous extensor lesions and symptomatic gluten-sensitive enteropathy (GSE). All lesions and GSE symptoms resolved with dapsone and a gluten-free diet. Our purpose is to illustrate an unusual presentation of pediatric DH.     

Arthrofibrosis: Etiology,classification, histopathology, and treatment

This article provides a complete review of arthrofibrosis following ACL reconstruction, and a complete review of theetiology, classification, and histology of arthrofibrosis. A clinician's guide to the recognition of arthrofibrosis and when the arthrofibrosis is clinically significant, treatment of arthrofibrosis after determination of arthrofibrosis, and its treatment to include surgical and nonsurgical management is noted. We emphasize prevention with appropriate indications and timing of ACL reconstruction and appropriate intraoperative surgical techniques for a correctly performed ACL reconstruction. The appropriate rehabilitation and expected clinical progress and parameters to follow after ACL reconstruction with emphasis on early recognition and early treatment will significantly improve the outcome of treatment of clinically significant arthrofibrosis and hopeful prevention of arthrofibrosis. By applying the techniques reviewed, prevention of arthrofibrosis is the orthopaedic surgeons best weapon.     

Solid Tumor Inhibitory and other Constituents of Casimiroa tetrameria

AIM:To isolate and characterize solid tumor inhibitory and other constituents from a bioactive extract of Casimiroa tetrameria((Rutaceae).METHODS:A crude extract of C.tetrameria obtained from the US National Cancer Institute Natural Product Repository and found to exhibit selective toxicity to solid tumor cells was subjected bioactivity-guided fractionation involving solvent-solvent partitioning,gel filtration,and chromatography.The structures of all isolated compounds were elucidated by spectroscopic analy...

LOS诱导的特异性抗体分泌细胞的ELISPOT法检测

目的 :动态测定卡他性莫拉氏菌 (Moraxellacatarrhalis,M .cat)脱毒脂寡糖 (dLOS)蛋白质结合疫苗诱导的抗体分泌细胞的应答状态。方法 :以M .catdLOS蛋白质结合疫苗滴鼻免疫BALB/c小鼠。应用酶联免疫斑点试验 (ELISPOT)检测免疫小鼠不同免疫诱导部位和免疫效应部位 ,包括 :鼻相关淋巴组织 (NALT)、脾脏、颈部淋巴结、鼻内容物、肺脏和派伊尔氏结的特异性抗体分泌细胞 ,并同时测定血清、鼻冲洗液、肺泡灌洗液、唾液及粪便提取液中特异性IgA、IgG和IgM的水平。结果 :M .catdLOS蛋白质结合疫苗免疫小鼠的NALT、脾脏、颈部淋巴结、鼻内容物、肺脏和派伊尔氏结中 ,均测出分泌LOS特异抗体的抗体分泌细胞 ,以鼻内容物中IgA分泌细胞的数目最多 ,其次是在NALT和肺脏中 ,这与特异性抗体测定的结果相一致。结论 :M .catdLOS蛋白质结合疫苗经滴鼻免疫 ,能刺激产生LOS特异的黏膜和全身抗体分泌细胞的应答。ELISPOT试验具有快速、灵敏、特异的优点 ,为动态分析单个抗体分泌细胞应答规律提供了新方法。     

Co‐occurring medical conditions in adults with Down syndrome: A systematic review toward the development of health care guidelines

Adults with Down syndrome (DS) represent a unique population who are in need of clinical guidelines to address their medical care. The United States Preventive Service Task Force (USPSTF) has developed criteria for prioritizing conditions of public health importance with the potential for providing screening recommendations to improve clinical care. The quality of existing evidence needed to inform clinical guidelines has not been previously reviewed. Using the National Library of Medicine (NLM) database PubMed, we first identified 18 peer reviewed articles that addressed co‐occurring medical conditions in adults with DS. Those conditions discussed in over half of the articles were prioritized for further review. Second, we performed detailed literature searches on these specific conditions. To inform the search strategy and review process a series of key questions were formulated a priori. The quality of available evidence was then graded and knowledge gaps were identified. The number of participating adults and the design of clinical studies varied by condition and were often inadequate for answering all of our key questions. We provide data on thyroid disease, cervical spine disease, hearing impairment, overweight‐obesity, sleep apnea, congenital heart disease, and osteopenia‐osteoporosis. Minimal evidence demonstrates massive gaps in our clinical knowledge that compromises clinical decision‐making and management of these medically complex individuals. The development of evidence‐based clinical guidance will require an expanded clinical knowledge‐base in order to move forward.     

Immunohistochemical investigation of voltage-gated potassium channel-interacting protein 1 in normal rat brain and Pentylenettrazole-induced seizures

1 Introduction To discover accessory subunit of the Kv4 A-type channel, three novel proteins termed Kv channel-interact- ing proteins were identified as KChIP1, KChIP2, and KChIP3, and another homologue KChIP4 was found latterly. These novel proteins turn out to have around 40% amino-acid similarity to neuronal calcium sensor-1 (NCS-1) and belong to neuronal calcium sensor (NCS) family, which consists of those EF-hand-containing Ca2 -binding pro- teins that express predominantly or …     

异体手移植1例:美国路易斯威尔经验

背景 依据国际复合组织移植大会的交流经验和猪异体肢体移植研究成功经验,我们制定了一个人类异体手移植计划。方法 通过全面的移植术前评估和患者的同意,选择移植物大小、性别、皮肤弹性相配的一个58岁的尸体供者的左手移植到一个失去左手13年的男性受者。免疫抑制治疗包括Simulect(一种新型免疫抑制剂,为竞争性IL-2受体阻断剂)诱导治疗和普乐可复、骁悉、强的松龙的维持治疗。结果 供手的冷缺血时间为310分钟。无术中或术后并发症。移植物皮肤在第6、20、27周发生了中等程度的排斥反应。通过静注甲基强的松龙,局部使用普乐可复(FK506)和氯倍他索(Clobetasol)缓解。温度觉、痛觉、压力觉在一年时到达手和手指。在术后一年,患者可以使用左手进行许多假肢没有的功能,例如投掷垒球、翻报纸、写字和系鞋带。结论 利用新型免疫抑制剂获得了异体手移植的早期成功。
