Specimens of a Praon species obtained in Italy from the large filbert aphid Corylobium avellanae Schrk. were compared with the British Museum types of Praon dorsale (Haliday 1833), and Praon longicorne Marshall 1891, the former recently considered a senior synonym of the latter. The comparison was carried out by utilizing two multivariate statistical approaches: Andrews plots and cluster analysis. Andrews plots have proven successful in morphometric comparison in anthropology between single human fossil specimens and series of individuals belonging to ape and human populations. The analysis were based on 11 morphological characters and 6 ratios between them. The comparison showed that the B.M. type of P. dorsale is homogeneous with the Italian population from C. avellanae,whereas the B.M. type of P. longicorne is characterized by morphological features which keep it separate from P. dorsale. A redescription of both species based on their well-preserved holotypes is given.

感染后炎性疾病:基于前瞻性随访的患者亚型

世界核心医学期刊文摘（神经病学分册） 2006年第3期2卷 28-29页

作者： Marchioni E. Ravaglia S. piccolo G. 方伯言 Institute of Neurology IRCCS C. Mondino University of Pavia Via Mondino 2 27100 Pavia Italy

Background: Acute disseminated encephalomyelitis (Ad- EM)refers to a monophasic acute multifocal inflammatory CNS disease. However, both relapsing and site-restricted variants, possibly associated with peripheral nervous system (PNS) involvement, are also observed, and a systematic classifi cation is lacking. Objective: To describe a cohort of postinfectious AdEM patien ts, to propose a classification based on clinical and instrumental features, and to identify subgroups of patients with different prognostic factors. Methods: I npatients of a Neurologic and Infectious disease Clinic affected by postinfectio us CNS syndrome consecutively admitted over 5 years were studied. Results: Of 75 patients enrolled, 60 fulfilled criteria for AdEM after follow-up lasting from 24 months to 7 years. Based on lesion distribution, patients were classified as encephalitis (20%),myelitis (23.3%), encephalomyelitis (13.3%), encephalomye loradiculoneuritis (26.7%), and myeloradiculoneuritis (16.7%). Thirty patients (50%) had a favorable outcome. Fifteen patients (25%) showed a relapsing cour se. Poor outcome was related with older age at onset, female gender, elevated CS F proteins, and spinal cord and PNS involvement. All but two patients received h igh-dose steroids as first-line treatment, with a positive response in 39 (67 %). Ten of 19 nonresponders (53%)benefited from high-dose IV immunoglobulin; 9 of 10 had PNS involvement. The data were not controlled. Conclusions: A high p revalence of “atypical variants”was found in this series, with site-restricte d damage or additional peripheral nervous system (PNS) involvement. Prognosis an d response to steroids were generally good, except for some patient subgroups. I n patients with PNS involvement and steroid failure, a favorable effect of IV im munoglobulin was observed.

目的：正畸热激活弓丝能够产生比超弹弓丝更轻、更符合生物学的力量．从而能够降低正畸初次就诊所产生的疼痛感。然而．该说法的证据却较少。本研究的目的即比较使用热激活弓丝（HANT）和超弹弓丝（SE）作为正畸初始弓丝就位后患者的疼痛感的差别。方法和材料：共纳入30例患者（男11例，女19例，年龄11～26岁）。上颌或下颌粘接金属托槽．随机使用0．016英寸热激活弓丝和0016英寸超弹弓丝，橡皮圈结扎入槽。要求患者使用视觉模拟量表（VAS）记录7d内不同时刻（8：00．12：00．16：00，2000．2400）的疼痛指数。结果：两组结果均显示疼痛程度最重的为第2天，疼痛程度最轻的为第7天：热激活弓丝组第2．3，4天的VAS评分均显著低于超弹弓丝组（P〈0.005）。针对服用止痛药、体育锻炼、合并其他来源的疼痛和伴随压力性事件等情况做出调整后．结果仍然相同。超弹弓丝组在第3天服用止痛药的频率明显高于热激活组（P〈0.05）。不同时间点间疼痛感未发现明显差异，牙列拥挤与疼痛程度未发现相关性．上下颔的疼痛感也无明显差异。结论：使用热激活弓丝能够降低正畸初诊疼痛感。
