Whistling face syndrome: MR imaging findings in the brain

Whistling face syndrome or cranio-carpotarsal dysplasia is a very rare disorder that consists of a characteristics facies and digital abnormalities. Magnetic resonance imaging investigation of the brain in this syndrome has not been reported previously. This communication describes the brain malformations in an infant with the syndrome, which covered delayed myelination, thickened and infolded cortices (cortical dysplasia), dysplastic corpus callosum, and agenesis of the inferior vermis.     

Remodeling Adult Nursing

This article describes a nursing education experience in which a critical thinking approach was planned and implemented. Background discussion on critical thinking concepts and related research provides a foundation for presentation of the Mackie teaching model. The model uses a community-based, family-centered scenario as the basis for developing problemfocused nursing intervention skills from a holistic viewpoint. Role expectations of students and faculty are outlined, and related implementation difficulties, together with their resolution strategies, are described. Evaluation methods and outcomes are reviewed in the conclusion.     

Elevated body mass index and mortality risk in the elderly

The purpose of this report was to perform a systematic review and meta-analysis of the studies examining the impact of an elevated body mass index (BMI) on mortality risk in elderly (> or =65 years) men and women. A variance-based method of meta-analysis was used to summarize the relationships from available studies. The summary relative risk of all-cause mortality from the 26 analyses that included a risk estimate for a BMI within the overweight range was 1.00 (95% confidence intervals, 0.97-1.03). The summary relative risk of all-cause mortality for the 28 analyses that included a risk estimate for a BMI within the obese range was 1.10 (1.06-1.13). These calculations indicate that a BMI in the overweight range is not associated with a significantly increased risk of mortality in the elderly, while a BMI in the moderately obese range is only associated with a modest increase in mortality risk.     

单发右位心的心血管造影与外科术后诊断对比研究

目的比较单发右位心的心血管造影与外科术后诊断,评价心血管造影诊断结果的准确性,探讨最佳的造影方法及投照体位.方法27例先天性单发右位心病例接受外科姑息性或根治手术治疗,回顾性分析其心血管造影资料（常规左、右室造影,其中8例行选择性心房造影,18例加行双斜位）,根据先天性心脏病节段分析法原则,将其与外科术后诊断进行对比研究.结果心血管造影诊断与外科术后诊断结果对比显示22例诊断基本一致,5例不一致,包括1例解剖校正型大动脉错位误诊为功能校正型大动脉错位,1例完全性大动脉错位误诊为功能校正型大动脉错位,1例单心室误诊为右室双出口（合并心房不定位误诊为心房正位）,2例解剖左室双出口误诊为功能校正型大动脉错位.结论单发右位心并复杂的心血管病畸形,因解剖复杂,在常规行双侧心室造影和正侧位造影基础上加行选择心房造影和双斜位造影,有利于达到准确诊断的目的.     

双支撑骨柱移植术治疗股骨头坏死的远期疗效分析

目的分析双支撑骨柱移植术治疗股骨头坏死的远期疗效。方法从1988年3月以来,采用双支撑骨柱移植术治疗成人股骨头坏死366例466髋,获5年以上随访者186例206髋,平均年龄32.2(20~60)岁。按病因分类:激素性者60例68髋,酒精性者86例96髋,激素加酒精者30例32髋,外伤性者10例10髋。ARCOⅡB、ⅡC、ⅢA、ⅢB、ⅢC、Ⅳ期患者分别为36、30、40、40、32、28髋。参照百分法进行疗效评价。结果术后所有患者的髋关节疼痛均获得明显缓解或消失,股骨头高度有不同程度增加,关节活动度有改善。平均随访时间10.5(5~16)年,手术前与随访时临床评价(疼痛、功能、关节活动度)、X线评价、总分数比较,差异均有统计学意义(P<0.01)。结果显示ⅡB~Ⅳ期优良率分别为83.3%、80.0%、75.0%、65.0%、40.6%、28.6%,总优良率为63.6%。Ⅱ期效果好(81.8%),Ⅲ期早期(ⅢA、ⅢB)效果较好(70%),ⅢC、Ⅳ期者效果差(35%)。期别间疗效依次降低,差异有统计学意义(P=0.0001)。30岁以内患者术后股骨头内植骨愈合较快,平均为3.2(2.9~3.5)个月。50~60岁患者植骨愈合需时较长,平均为5.5(4.4~6.4)个月。结论该术式治疗股骨头坏死的远期疗效良好,治疗效果与股骨头坏死期别有关,尤其适用于股骨头坏死Ⅱ期和Ⅲ期的早期病例。     

美国汉学界区域史、地方史研究的兴起

六十年代以来，区域研究与地方史理论在美国汉学界开始流行。文章试图在全面厘清汉学区域研究及地方史视角兴起原因的基础上，分析这一现象在思想文化研究中的利弊得失，以期展现中国研究的复杂性并反思我们引进海外汉学成果时的态度。     

Significance of diffuse cardiac activity on In-111 labeled leucocyte scans

To assess the significance of diffuse cardiac activity (DCA) seen on In-111 labeled leukocyte scans, we reviewed 87 studies performed over the last 4 years. Inflammatory cardiac conditions were seen as frequently in patients with DCA (15%) as those without (7%, P=0.3). There was a higher ratio of RBC:WBC in the final WBC preparation in the false-positive DCA group than the true positive DCA and no DCA groups. False-positive studies showing DCA are most likely due to residual blood pool activity.Presented in part, 70th annual meeting, Radiological Society of North America, Washington D.C., 25 November 1984     

Sumatriptan nasal spray in the acute treatment of migraine in adolescents and children

About 4-10% of children and adolescents suffer from migraine. In the last few years, several studies have been performed to assess the efficacy and safety of triptans for the acute treatment of migraine in children and adolescents. Only sumatriptan nasal spray has been approved for the treatment of acute migraine with or without aura in adolescents aged 12-17 years in Europe. This review describes the results of the studies with sumatriptan nasal spray that have been performed in children and adolescents, including a study performed in the Netherlands.     

男性胆囊结石患者血清性激素和前列腺素改变的探讨

借助RIA,对28例胆囊结石男性(平均57.5岁)及26名健康中、老年男性(平均63.3岁)进行了血清雌二醇(E_2)、孕酮、睾酮和前列腺素类(PGs)检测,以探索胆石形成机理。结果,1)在胆石男病人中.平均E_2和平均孕酮水平均高,他们的平均睾酮则低下,与健康对照男性相应诸值比较,差异非常显著或显著(P<0.001,0.05,0.05);2)至于平均PGs,胆石男性组者与健康对照男性相比,前者也相当高(23.01pg/ml对16.31pg/ml),只是两组间差异尚无统计学意义。作者等初步设想,胆石男性小,如同胆石女性那般,本症也可能是某种垂体性腺激素分泌紊乱性疾病。     

绝经后高血压危险因素的Meta分析

背景 流行病学研究表明,绝经后女性的高血压患病率高于老年男性。近年来,有关绝经后高血压的临床表现、病理特征、发病机制、治疗方法等受到越来越多的关注,但由于受到研究设计、样本量、人群特征、资源不足等因素的影响,其危险因素的研究结果不一致且缺乏全面报道。目的 运用系统评价方式探讨女性绝经后高血压的危险因素,为更好地预防和管理绝经后高血压提供循证证据。方法 于2022年1—5月,计算机检索中国知网、万方数据知识服务平台、中国生物医学文献服务系统、PubMed、EmBase、the Cochrane Library、Web of Science电子数据库,获取与绝经后高血压危险因素相关的队列及病例对照研究。检索时限为建库起至2022-05-20。由2名研究者独立根据纳入和排除标准筛选文献、提取资料,采用纽卡斯尔-渥太华量表（NOS）对所提取的文献进行偏倚风险评估,将得分≥6分（高质量）的文献纳入研究,最后采用RevMan 5.3对其进行Meta分析。结果 共纳入10篇文献,5篇为队列研究,5篇为病例对照研究,共涉及16个危险因素,总样本量为34 864,且均为高质量文献。Meta分析结果显示,...
