Association between serum 25-hydroxyvitamin D concentration and severity of first-diagnosed bullous pemphigoid in older adults

BackgroundHigher vitamin D status has been associated with symptom improvement and decreased risk of various autoimmune disorders. Our objective was to determine whether higher serum 25-hydroxyvitamin D (25OHD) concentration correlated with less severe first-diagnosed bullous pemphigoid (BP) in older inpatients.MethodsThis cross-sectional study was performed from November 2012 to February 2014 among 30 consecutive older inpatients (21 women; mean ± SD, 83 ± 7 years; all Caucasian) with a de novo diagnosis of active BP recruited in the Department of Dermatology of Angers University Hospital, France. The severity of BP was graded clinically on the basis of i) the number of bullae during the first three days of hospitalization (grade 0–4, worse), and ii) the extent of the lesions (grade 0–5, worse).ResultsSixteen participants had ≤ 5 bullae at the time of diagnosis, 8 had 6–20 bullae, 3 had 20–50 bullae, and 3 had >50 bullae. The lesions were spread over 5 cutaneous areas in 5 participants (17%). The median 25OHD concentration was 23 [IQR, 16–42] nmol/L. Serum 25OHD concentration was inversely correlated with the bullae grade (ρ = − 0.38, p = 0.04) and the lesion extension grade (ρ = − 0.50, p = 0.005).ConclusionsHigher serum 25OHD concentration correlated with less severe BP prior to initiation of treatment among our sample of older inpatients. This result suggests that vitamin D may be involved in the pathophysiology of BP and could serve as prognostic biomarker of BP.     

The Long-Term Effective Rate of Different Branches of Idiopathic Trigeminal Neuralgia After Single Radiofrequency Thermocoagulation: A Cohort Study

To evaluate the efficacy of computed tomography (CT) guided single radiofrequency thermocoagualtion (RFT) in 1137 patients with idiopathic trigeminal neuralgia after a follow-up period of 11 years, specially focused on duration of pain relief in different branches of trigeminal nerve, side effect, and complications.Retrospective study of patients with idiopathic trigeminal neuralgia treated with a single CT guided RFT procedure between January 2002 and December 2013.The mean follow-up time was 46.14 ± 30.91 months. Immediate postprocedure pain relief was 98.4%. V2 division obtained the best pain relief rate: 91%, 89%, 80%, 72%, 60%, and 54% at 1, 3, 5, 7, 9, and 11 years, respectively. No statistical difference pairwise comparison was in other groups. The complications included masseter muscle weakness, corneitis, diplopia, ptosis, hearing loss, limited mouth opening, and low pressure headache. Masticatory weakness mostly occurred in patients with V3 branch involvement, while Corneitis and Diplopia all in patients with V1 branch involvement. No mortalities observed during or after RFT.All different branches division of trigeminal neuralgia achieved comparable satisfactory curative effect; V2 obtained the best excellent pain relief, after RFT procedure. Facial numbness is inevitable after RFT, which patients who have pain in all 3 trigeminal divisions and patients who desire no facial numbness should be cautious. Masticatory weakness is mainly related with V3 injured, while Corneitis and Diplopia in patients with V1 injured by RFT.     

以失用为主要表现的胼胝体梗死

目的探讨胼胝体梗死的临床表现、病因及鉴别诊断特点。方法对2005年7月收治的1例53岁男性胼胝体梗死患者的临床表现、影像学特点、病因机制及其治疗过程进行回顾分析。结果临床主要表现为发作性黑蒙、言语不利,既往有高血压、糖尿病、脑梗死、吸烟、饮酒史,体格检查以失用为主要表现。头部MRI检查可见左侧脑室旁、胼胝体梗死,右侧基底节、脑桥陈旧性腔隙性梗死;脑血管造影检查显示为多发性血管狭窄,其中以左侧大脑中动脉、右侧颈内动脉及基底动脉最为严重。经颈内动脉内膜剥离术及颈内动脉支架植入术治疗,临床症状缓解。结论失用可以是胼胝体梗死的主要表现,其病因是在脑动脉粥样硬化基础上的血流动力学改变,患者预后良好。

[18F]-labeled 2-methoxyphenylpiperazine derivative as a potential brain positron emission tomography imaging agent

This study reports the synthesis and characterization of N-(3-(4-(2-methoxyphenyl)piperazin-1-yl)propyl-4-[¹⁸F]fluorobenzamide ([¹⁸F]MPP3F). The total reaction time for [¹⁸F]MPP3F, including final high-performance liquid chromatography purification, was about 3 h. Typical decay-corrected radiochemical yield was 18.4±3.1%. The radiochemical purity was >98%. Biodistribution in mice showed that [¹⁸F]MPP3F is a potential brain imaging agent for positron emission tomography. The brain uptake of [¹⁸F]MPP3F was 6.59±0.77% Injected Dose/g at 2 min post-injection time. A brain-to-blood ratio of 3.67 was reached at 15 min after injection.     

家族性与散发性严重急性呼吸综合症（SARS）患者的病死率与重症率的研究

目的研究家族性与散发性SARS患者的重症率及病死率的区别。方法把61例SARS患者分为家族性病例和散发性病例两组，家族性病例23例，散发性病例38例，分别对重症率及病死率进行比较。结果家族性患者的重症率47．8％，散发性患者的重症率22．5％（P〈0．05），家族性患者的病死率21．7％，散发性患者的病死率5．2％（P〉0．05），本组资料尚未发现病死率有统计学明显差异。可能与病例数较少有关。结论家族性SARS患者的重症率明显高于散发性SARS患者。
