Akinetic Mutism and Cognitive-Affective Syndrome Caused by Unilateral PICA Infarction

A 42-year-old man with left posterior inferior cerebellar artery (PICA) infarction presented with akinetic mutism and cognitive impairment. Initially he suffered from akinetic mutism and MRI-documented infarction in the distribution of the left PICA. Twelve days later he developed cognitive impairment. Neuropsychological tests were performed, with the results corrected for age and education being compared with published Korean norms. Impaired performances were evident on executive function testing, with difficulties in planning, abstract reasoning, set-shifting, and perseveration. Akinetic mutism and cognitive-affective syndrome may be a manifestation of unilateral PICA infarction.     

少年儿童颞下颌关节紊乱综合征的错雅(牙合)特征

①目的 探讨少年儿童颢下颌关节紊乱综合征(TMJD)的错拾特征。②方法 用一般口腔检查工具对青岛地区的550例TMJD病人进行拾检查。③结果 80．0％的病人有不同程度的错He，其中个别牙齿错位所占的百分率最高(42．4％)，其次为高度不调、长度不调和宽度不调；不同牙龄期病人错He特征不同。④结论 本研究结果可以作为TMJD早期正畸治疗以及治疗时对错He分析和诊断的参考。     

冠心病患者血清同型半胱氨酸与叶酸、维生素B12水平的变化

目的 探讨冠心病患者血清同型半胱氨酸(HCY)与叶酸、维生素B12浓度的变化及其相关性。方法 选择84例经冠状动脉造影术证实为冠心病的患者，应用荧光偏振免疫分析法(FPIA)测定血清HCY浓度，离子捕获免疫分析法(ICIA)测定血清叶酸浓度，非均相微粒子酶免疫分析法（MEIA)测定血清维生素B12浓度。结果 冠心病患者血清HCY浓度增高，与正常对照组比较有显著性意义(P＜0．001)，而叶酸、维生素B12浓度则降低，与正常对照组比较有显著性意义(P＜0．001)，以上两种变化呈负相关(P＜0．001)。结论 同型半胱氨酸血症是冠心病的新的独立危险因素，叶酸、维生素B12缺乏可能是诱发高HCY的重要因素。

温针灸治疗颞下颌关节功能紊乱病36例

目的:比较温针灸与口服西药治疗颞下颌关节功能紊乱病的疗效。方法:治疗组36例取下关、牵正、颊车、阿是穴、合谷(双)行温针灸,对照组口服地西泮、吲哚美辛。结果:治疗组治愈率80·6%、总有效率100%,对照组治愈率40·6%、总有效率78·1%,两组有非常显著性差异(P<0.01)。结论:温针灸治疗颞下颌关节功能紊乱病方法简单,疗效显著。     

急性心肌梗塞猝死的诱因及抢救(附13例报告)

本文报告了急性心肌梗塞猝死13例。分析猝死的诱因主要有血清钾浓度降低,严重心律失常,包括室内传导阻滞、室性并行心律、室性早搏等。近年来急性心肌梗塞的发病率日趋增高,心源性猝死也随之增多,有必要对猝死的诱因进行探讨,以采取有效的抢救措施。     

Enhancement of hepatic hemangiomas with levovist on coded harmonic angiographic ultrasonography.

OBJECTIVE: To evaluate the pattern of contrast enhancement with Levovist on coded harmonic angiographic ultrasonography of hepatic hemangiomas. METHODS: Twenty hemangiomas were evaluated with coded harmonic angiographic ultrasonography and a microbubble contrast agent. Verification of the diagnosis of a hemangioma was made by means of dynamic computed tomography (n = 8), dynamic magnetic resonance imaging (n = 1), radionuclide scanning (n = 6), or follow-up ultrasonography (n = 5). Ultrasonographic images were obtained before contrast agent administration and with a bolus injection of 2.5 g of a microbubble contrast agent (300 mg/mL Levovist; Schering AG, Berlin, Germany) every 10 to 15 seconds for 5 minutes. The contrast enhancement patterns of the 20 hemangiomas were assessed. RESULTS: The tumor diameters as measured on ultrasonography were 7 to 97 mm (mean, 26.7 mm). Of the 20 hemangiomas, peripheral globular enhancement with progressive centripetal fill-in was shown in 15 (75%), rimlike enhancement with progressive centripetal fill-in was shown in 2 (10%), and homogeneous enhancement was shown in 1 (5%). In the remaining 2 lesions (10%), the enhancement patterns could not be seen, because they were not found on coded harmonic angiographic ultrasonography. CONCLUSIONS: Coded harmonic angiographic ultrasonography with a microbubble contrast agent can depict the typical enhancement pattern in most hepatic hemangiomas.
