The nature of the disorder underlying the inability to retrieve proper names

Two patients with the syndrome of proper name anomia were investigated. Both patients were only able to produce around 50% of the names of contemporary celebrities, but performed significantly better on a task calling for naming of historical figures. The names of relatives and friends were spared in one patient, while the other retrieved names of people known since childhood much better than those of people familiar to him since the age of 25. Geographical names, names of monuments and masterpieces were preserved. The above dissociations are taken to imply that in moderately impaired patients, a temporal gradient effect concurs to modulate the severity of the naming block.

A similar impairment was found in both patients when they attempted to retrieve or relearn familiar telephone numbers. This finding suggests that the core of the disorder resides in the inability to gain access to words used to identify a single entity, regardless of whether they belong to the class of proper or common names.     

Face shields for infection control: A review

Face shields are personal protective equipment devices that are used by many workers (e.g., medical, dental, veterinary) for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, and spatter of body fluids. Face shields are generally not used alone, but in conjunction with other protective equipment and are therefore classified as adjunctive personal protective equipment. Although there are millions of potential users of face shields, guidelines for their use vary between governmental agencies and professional societies and little research is available regarding their efficacy.     

Effect of Emdogain enamel matrix derivative and BMP-2 on the gene expression and mineralized nodule formation of alveolar bone proper-derived stem/progenitor cells

The objective of this study was to evaluate the effect of Emdogain (Enamel Matrix Derivative, EMD) and Bone Morphogenetic Protein-2 (BMP-2), either solely or in combination, on the gene expression and mineralized nodule formation of alveolar bone proper-derived stem/progenitor cells.Stem/progenitor cells were isolated from human alveolar bone proper, magnetically sorted using STRO-1 antibodies, characterized flowcytometrically for their surface markers' expression, and examined for colony formation and multilineage differentiation potential. Subsequently, cells were treated over three weeks with 100 μg/ml Emdogain (EMD-Group), or 100 ng/ml BMP-2 (BMP-Group), or a combination of 100 ng/ml BMP-2 and 100 μg/ml Emdogain (BMP/EMD-Group). Unstimulated stem/progenitor cells (MACS⁺-Group) and osteoblasts (OB-Group) served as controls. Osteogenic gene expression was analyzed using RTq-PCR after 1, 2 and 3 weeks (N = 3/group). Mineralized nodule formation was evaluated by Alizarin-Red staining.BMP and EMD up-regulated the osteogenic gene expression. The BMP Group showed significantly higher expression of Collagen-I, III, and V, Alkaline phosphatase and Osteonectin compared to MACS⁺- and OB-Group (p < 0.05; Two-way ANOVA/Bonferroni) with no mineralized nodule formation.Under in-vitro conditions, Emdogain and BMP-2 up-regulate the osteogenic gene expression of stem/progenitor cells. The combination of BMP-2 and Emdogain showed no additive effect and would not be recommended for a combined clinical stimulation.

吻合指神经背侧支的指动脉逆行岛状皮瓣修复指腹指端

目的:探讨吻合指神经背侧支的指动脉逆行岛状皮瓣修复指腹指端缺损的疗效。方法:对11例12指指端指腹缺损,行吻合指神经背侧支的指动脉逆行岛状皮瓣修复治疗,术后辅以积级感觉再训练康复治疗。结果:术后皮瓣全部成活。平均随访时间11个月,依据国际手外科联合学会的周围神经损伤临床疗效的评定的方法:感觉恢复S5为6指,S4为2指,S3为2指;皮瓣两点辨别觉:正常为6指,减退为4指。结论:应用吻合指神经背侧支的指动脉逆行岛状皮瓣修复指腹指端缺损,术后辅以积级感觉再训练康复治疗,是促进皮瓣感觉功能恢复行之有效的方法。     

抗结核治疗中药物热48例诊治体会

目的探讨抗结核药物所致的药物热的品种、发生率及症状,提高对药物热的认识。增强药物热和其他原因引起的发热的鉴别意识。方法回顾总结抗结核治疗中药物热48例,观察导致药物热的品种,发生的时间,伴随的症状及解决的方法。结果抗结核药物发生药物热的频率较高,尤以利福平、对氨基水杨酸钠、链霉素最常见。结论结核病治疗过程中需要关注抗结核药物发生药物热的可能性,尤其是出现反常发热及嗜酸性粒细胞升高时,及时停药是治疗的关键。     

火炬椎弓根内固定器械的研制及临床生物力学研究

目的:后路短节段椎弓根内固定器械治疗胸腰椎骨折及腰椎滑脱安全且有效,介绍自行研制的火炬内固定器械及在胸腰椎骨折及腰椎滑脱中的生物力学测试。方法:通过器械生物力学测试,临床治疗14例患者(骨折10例、滑脱4例),对复位及固定效果进行观察。结果:术后胸腰椎骨折均满意复位,腰椎滑脱中3例退行性滑脱未完全复位,1例崩裂性滑脱复位满意,随访均无高度丢失、断钉、松动、椎体滑移加重等并发症。结论:该器械结构简单、操作简便,固定坚强、稳定,但对腰椎滑脱的治疗有一定局限性,其分离复位间距的适当量化对评价手术效果有一定的指导意义。
