Rare diseases mimicking acute vertebrobasilar artery thrombosis

Acute ischaemia of the vertebrobasilar circulation leads to a variety of clinical manifestation and is mostly due to cardiogenic or artery-to-artery embolism. We describe four neurological emergency situations involving vertebrobasilar artery aclusion of other origins: basilar migraine, extrinsic compression by rheumatoid inflammatory tissue, generalized vasculitis in subacute rheumatic fever and basilar artery dissection. The differential diagnosis of acute vertebrobasilar artery occlusion may have an important impact on patient management.     

流行性出血热82例误诊分析

目的 :探讨流行性出血热 (EHF)误诊情况 ,提高临床医师对本病的早期诊断水平。方法 :将我院 1982年 1月～ 1991年 12月和 1992年 1月～ 2 0 0 1年 12月各 10年收治的出血热和误诊情况进行回顾性分析。结果 :前 10年共收治EHF 4 82例 ,其中误诊 6 0例 ,后 10年收治 5 2例 ,误诊 2 2例 ,误诊率分别为 12 %和 4 3% ,而误诊疾病竟达2 2种之多。结论 :在任何季节里对有发热、出血的病人我们应高度警惕有可能是EHF ,及时作相关检查。     

新疆出血热病毒与流行性出血热病毒的生物学特性比较

本文通过免疫荧光(IF)和电镜(EM)技术对新疆出血热(XHF)及流行性出血热(EHF)病毒的生物学特性在Vero E_6及LLC-MK_2两株传代细胞上进行了比较。两种病毒感染两株细胞后免疫荧光染色有两种不同的荧光形态特征,两种病毒对细胞的敏感性明显不同,XHF病毒在LLC-MK_2细胞上感染后6～8天可出现明显的细胞病变,而EHF病毒感染此细胞后则不引起病变。电镜观察到两种病毒在LLC-MK_2细胞中都能形成与布尼病毒相似的形态特征。     

Post-ictal fever: a rare symptom of partial seizures

Although fever may induce seizures, especially in children, its occurrence following epileptic spells has been rarely described, except from generalized convulsive status epilepticus. We present two patients suffering from focal seizures accompanied by episodes of post-ictal fever, and review similar reports in the literature of the last 40 years. Temperature changes following non-convulsive seizures might be induced by gene upregulation occurring in the hypothalamus, the nucleus tractus solitarius, or in other brain regions, producing a local inflammatory response. Direct propagation of electrical discharges seems less consistent with the timing of development of this symptom. Heterogeneity of reported clinical features argues against the assumption of a definite localizing or lateralizing value for post-ictal fever.

Stephen Girard (1750–1831): a one-eyed American patriot

Stephen Girard trader, banker, millionaire, and patriot lived 81 full and exciting years. Apparently born with a blind or amblyopic right eye, he emigrated from Bordeaux. France, via Santa Domingo to the United States, and finally settled in Philadelphia, where he developed a successful maritime trade. Ultimately, Girard became the first multimillionaire in the United States. Extremely generous, he often walked from his home in the center of Philadelphia to his farm in what is now South Philadelphia distributing shoes to needy children. Probably Girard’s most heroic gestures were his gallant fight against the yellow fever epidemic in 1793 and his loan to the U.S. government during the War of 1812, which allowed the bankrupt country to continue the conflict and ultimately to win the war. Presented, in part, at the tenth annual meeting of the David G. Cogan Ophthalmic History Society, the College of Physicians of Philadelphia, March 8 and 9, 1997.     

实验动物大白鼠型流行性出血热流行病学和临床症状调查

本文对59名接触实验动物大白鼠引起23例流行性出血热(EHF)的流行病学和临床症状进行了调查,发病率为38.98%。发病的有副教授、讲师、助教、研究生等。发病多在春季,年龄组在21～40岁,男多于女。经间接免疫荧光技术检查,大白鼠肺EHFV抗原阳性率为32.69%。临床分型以中型为多,其次为重型和轻型。临床症状以发热、头痛、腰痛、全身痛、食欲不振、酒醉貌为主,没有死亡病例。血清间接免疫荧光抗体IgG在1:320～1:5 120之间的占91.30%。     

SARS临床特点分析

目的 :探讨SARS的临床特点、诊治方法。方法 :对 2 0 0 3年 3月至 2 0 0 3年 5月收治的 2 9例传染性非典型肺炎患者进行回顾性分析 ,总结其流行病学特点、临床表现、血常规及影像学检查特点。结果 :本组 2 9例全部以发热为首发症状 ,有明确接触史者 2 5例 (占 86 .2 % ) ,第一次血常规白细胞降低者有 8例 (占 2 7.6 % ) ,淋巴细胞计数 <0 .9× 10 9 L者 19例 (占 6 5 .5 % ) ,白细胞计数出现进行性下降者 2 2例 (占 75 .9% )。所有患者胸片显示肺部阴影 ,其中迅速进展者 18例 (占 6 2 .1% )。治疗采用抗病毒、抗感染、支持等综合治疗 ,重症患者使用大剂量甲泼尼龙和无创机械通气。结论 :流行病学史、临床特点是早期诊断的关键 ,治疗采取综合方法 ,对重症患者使用大剂量激素、无创机械通气治疗有效
