Anaplastic thyroid carcinoma: diagnostic challenges,histopathologic features and ancillary testing

Anaplastic thyroid carcinoma (ATC) is an aggressive thyroid malignancy with high mortality rate. This malignancy arises in thyroid follicular cells either denovo or with an associated differentiated thyroid carcinoma component. Clinically, it usually presents as a rapidly enlarging mass, pain and locally compressive symptoms. Histopathologic variability and heterogeneity often pose diagnostic challenges, especially in scant and paucicellular specimens. This article describes the clinical, histopathologic and molecular features of ATC and also addresses the associated diagnostic limitations and challenges.     

Thyroid Embolization for Nonsurgical Treatment of Nodular Goiter: A Single-Center Experience in 56 Consecutive Patients

PurposeTo investigate the safety and efficacy of thyroid artery embolization (TAE) in the treatment of nodular goiter (NG).MethodsDuring a 5.5-year period, 56 consecutive patients with a NG underwent TAE. In Group A, there were 20 patients with a solitary/dominant 5–11-cm nodule, and in Group B, there were 36 patients with numerous nodules. Of the 56 patients, 47 (84%) had a retrosternal goiter and 25 had hyperthyroidism. In all patients, clinical and radiological evaluations were made at baseline and 6 months after TAE, and these parameters were statistically compared.ResultsIn 56 patients, 145 of the 146 thyroid arteries were successfully embolized. The 30-day mortality rate was 1.8%. Minor and major complications occurred in 25 and 2 patients, respectively. Six months after the TAE, the mean nodule volume was reduced from 80.2 mL to 25.0 mL, the mean thyroid volume was reduced from 147.0 mL to 62.6 mL, and the mean intrathoracic extension was reduced from 31.7 mm to 15.9 mm (P < .001). Of the 22 patients with non–Graves hyperthyroidism, 19 (86%) became euthyroid. The mean thyroid-related patient-reported outcome scores improved from 155.4 to 70.4 (P < .001). Of the 51 patients, 50 (98%) declared that they would recommend TAE to other patients with NG.ConclusionsTAE is safe and effective for the treatment of NG, with a significant volume reduction of the nodule(s) and thyroid gland.     

脊柱后路内固定术后硬膜外血肿的预防与护理体会

目的 探讨脊柱后路内固定术后硬膜外血肿的预防与护理体会。方法 遵照回顾性分析法选择我院2013年2 月～2018 年2 月纳入的60 例脊柱后路内固定术患者，依照不同理疗方式进行分组。其中30 例给予常规药物治疗作为对照组，另30 例除了常规治疗之外实施综合护理作为研究组，记录两组硬膜外血肿、腰椎术后血肿及颈椎术后血肿发生率，分别在干预前后进行生活质量评分（QOL）调查，出院时发放满意度调查问卷表，对比两组干预结果。结果 研究组血肿发生率为6.67%，明显低于对照组的20.00%（P＜0.05）。干预前两组的食欲、精神、睡眠、疼痛及日常生活评分相比差异无统计学意义（P＞0.05），干预后研究组的各项评分均高于对照组（P＜0.05）。研究组对干预效果的满意度为90.00%，明显高于对照组的76.67%（P＜0.05）。结论 护理干预运用于脊柱后路内固定中效果显著，能够有效减少硬膜外血肿的发生率，提升生活质量，促进病情稳定，患者满意度较高，可维持良好医患关系。     

比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤安全性和有效性的Meta分析

目的比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤的安全性和有效性。方法计算机检索1990至2018年颅内未破裂动脉瘤的所有临床对照研究。两名研究员分别纳入研究、提取数据、质量评价并应用Rev Man5. 0软件进行数据处理。结果最终纳入21篇文献,病例数109114例。Meta分析结果提示:手术夹闭组动脉瘤闭塞率为88. 2%,平均住院时间7. 7天,均高于介入栓塞组的65. 3%和4. 1天,P 0. 05。介入组患者的短期死亡率和致残率分别为0. 61%和2. 1%,均低于手术组的1. 27%和4. 7%,P 0. 05。介入组患者的1年期死亡率和致残率(2. 5%、2. 5%)均与手术组(2. 2%、1. 8%)无明显差异,P 0. 05。漏斗图未发现发表偏倚。敏感性分析结果一致。结论介入栓塞相比于手术夹闭可缩短患者的住院时间,降低患者的短期不良预后发生率。但是动脉瘤的闭塞率较低,1年期预后与手术夹闭无明显差异。据此推测手术夹闭患者的长期预后可能要好于介入栓塞,手术夹闭更适合于年轻患者。     

Angiopathie amyloïde cérébrale ou atteinte des microvaisseaux cérébraux en rapport avec l’HTA : un challenge clinique

Cerebral amyloid angiopathy (CAA) is a entity characterized by degenerative Amyloïd deposits in the walls of the meningeal and cortical vessels. It is considered as the second cause of primitives cerebral hemorrhage in elderly. The differential diagnosis between AAC and hypertension-related cerebral small vessel diseases is difficult and represent a true challenge for the clinician. We report two cases of cerebral small vessel diseases revealed by malignant hypertension.
