Hemiparkinsonism associated with the unilateral striatal necrosis: a case report

We report a patient with hemiparkinsonism associated with unilateral striatal necrosis of the contralateral side. The patient was an 18-year-old woman who had a two-month-history of difficulty in executing skilled movements with her right upper extremity. Neurological examination revealed that she had cogwheel rigidity and bradykinesia in her right upper and lower extremities. MRI revealed a well-delineated low signal intensity in T1-weighted and high signal intensity in T2-weighted images in the region of the putamen on the left side. Her laboratory data were unremarkable and mitochondrial gene mutation studies revealed no abnormality. It is extremely rare to encounter a case of parkinsonism associated with unilateral striatal necrosis.

以反复眩晕为主诉的单侧多发性前庭神经鞘瘤1例报道

<正>前庭神经鞘瘤也称听神经瘤^[1],为内听道、桥小脑角区最常见的良性肿瘤。它会引起听力下降、耳鸣或眩晕;随着肿瘤的生长并向小脑脑桥角扩展,压迫脑桥、延脑,并出现脑积水、颅内高压,进而危及患者生命^[2]。2021年8月我院收治了1例以眩晕为主诉的多发性前庭神经鞘瘤患者,后转诊至301医院,成功为患者施行了右侧迷路入路肿瘤切除手术,术中证实为右耳迷路多发性前庭神经鞘瘤。现对该病例报道如下:     

腰椎滑脱症外科治疗策略选择

目的探讨不同类型腰椎滑脱症及合并症的手术治疗方式、疗效及优缺点。方法2000年2月～2004年4月应用后路椎弓根螺钉复位内固定后，分别采用后外侧植骨融合术、后路椎体间植骨融合术及前路椎体问植骨融合术治疗不同类型腰椎滑脱症及合并症的患者78例，比较术后及随访时疗效、滑脱椎体复位率、椎间隙高度恢复率、植骨融合率以及复位丢失率。结果术后28例Ⅰ度滑脱及37例Ⅱ度腰椎滑脱患者获得解剖复位．9例Ⅱ度滑脱及4例Ⅲ度腰椎滑脱患者矫正至Ⅰ度滑脱。随访时总体优良率为89．72％，42例椎体间植骨患者植骨融合良好，滑脱椎体复位无丢失，椎间隙高度维持良好；36例后外侧植骨者有12例复位丢失，2例椎弓根螺钉松动，2枚椎弓根螺钉断裂：结论对小于Ⅱ度退变性腰椎滑脱合并腰椎管狭窄者宜选用后路椎弓根钉复位固定加后外侧植骨融合术；对峡部裂性腰椎滑脱合并腰椎管狭窄者宜选用后路椎弓根钉固定加椎体间植骨融合术；对Ⅱ度以上峡部裂性单纯腰椎滑脱者以及腰椎滑脱翻修者宜选用后路椎弓根钉固定加前路椎体间植骨融合术。     

胸椎旁路法植入椎弓根螺钉的力学实验研究

目的：研究在胸椎节段应用椎弓根旁路法植入椎弓根螺钉的力学可行性。方法：5副成人新鲜尸体胸椎（T1-8）, 分解为40个单一椎体标本,每一标本左右两侧分别使用经椎弓根入路法（n=40）和旁路法（n=40）植入螺钉,并进行螺钉沿椎体矢状轴拔出强度的力学测量,比较两种方法的拔出强度。结果：旁路法植入螺钉后出现两种情况A和B,A：19个椎体（47.5%）,为螺钉经横突后沿椎弓根外壁固定至椎体;B：21个椎体（52.5%）,为螺钉经椎弓根外侧皮质至椎体。旁路法中A植入螺钉的拔出强度为（827.01±260.00）N,旁路法中B植入螺钉的拔出强度为（954.25±254.00）N。结合A、B两种情况,旁路法中植入螺钉的平均拔出强度为（890.63±342.00）N,胸椎经椎弓根入路螺钉的拔出强度为（1 001.23±220.00）N,二者比较,旁路法螺钉的平均拔出强度较经椎弓根入路法螺钉的拔出强度降低11.04%,但差异无显著性（P>0.05）。结论：胸椎椎弓根旁路法植入椎弓根螺钉在力学上是可行的。     

内皮祖细胞对狭长窄蒂皮瓣成活面积的影响

目的研究大鼠骨髓来源的内皮祖细胞（EPC）对狭长窄蒂皮瓣成活面积的影响。方法 SD大鼠15只,12只大鼠背部两侧各设计制作1块皮瓣,皮瓣设计为：蒂宽=蒂长=0.8 cm,蒂部所携带直径为3.5 cm的皮瓣,形状类似＂乒乓球拍＂,建立皮瓣的动物模型,随机分为两组：对照组及实验组;另3只大鼠,冲洗骨髓腔,密度离心法获得单个核细胞;在适宜的培养环境中（EGM-2MV培养液）培养出EPC;鉴定细胞CD34、CD133、vWF及VEGFR-2表型,并将目的细注射移植于皮瓣,对实验组及对照组皮瓣进行大体观察,测量皮瓣成活面积,计算局部毛细血管密度。结果注射EPC的皮瓣的存活面积以及毛细血管密度显著高于对照部位（P〈0.05）。结论 EPC移植于狭长窄蒂皮瓣后,加速皮瓣缺血缺氧组织再血管化,改善皮瓣缺血缺氧状态,扩大皮瓣成活面积。     

Island Pectoralis Major Myocutaneous Flap: An Indian Perspective

The aim of this study is to conceive a method of raising an island PMMC flap, so as to circumvent its drawbacks of bulk, flap length and the difficulty of developing this flap in female patients. And to consider island PMMC flap as a viable reconstructive option in head and neck surgeries, especially in peripheral centres. Ours is an experimental case series. The study was done at Sri Devaraj URS Medical college, Tamaka, Kolar. Between 2009 and 2010, head and neck reconstruction was performed using this method in 20 patients who had oral cancer (18), carcinoma supraglottis (1) and mucoepidermoid carcinoma parotid (1). The patients age ranged from 16 to 75 years, and there were 15 women and 5 men. Nineteen of our patients underwent primary surgery and one patient was operated for residual disease. In (16) patient, island pmmc flap was used for intra oral closure. In (4) patients the flap was spiraled for providing skin cover. Four patients developed complications. Three were minor complications of margin necrosis and wound dehiscence, which were managed conservatively. One patient developed orocutaneous fistula, which required secondary suturing. None of our patients had a total necrosis of the flap. Island PMMC flap is still a very useful and viable option for reconstruction in head and neck surgeries, especially in lateral gingivo buccal tumours and other head and neck tumours. In institutions where microvascular expertise is not available, island PMMC flap can be an alternative with results comparable to that of free tissue transfer.
