腮腺切除术中沿面神经总干顺行解剖面神经的效果及安全性

目的探讨腮腺切除术中应用沿面神经总干顺行解剖面神经的治疗效果及安全性。方法选取我院2016年2月至2019年3月收治的60例择期行腮腺切除术的患者,随机分为观察组与对照组各30例。对照组沿面神经总干逆行解剖面神经,观察组沿面神经总干顺行解剖面神经,观察两组患者术后1个月面神经功能及术后并发症发生情况。结果术后1个月,两组患者的面神经功能分级比较无统计学差异(P>0.05);观察组的术后并发症发生率为10.00%,明显低于对照组的33.33%(P <0.05)。结论临床行腮腺切除术中,沿面神经总干顺行解剖面神经可降低术后并发症发生率,值得推广。     

Oral Everolimus for Treatment of a Giant Left Ventricular Rhabdomyoma in a Neonate—Rapid Tumor Regression Documented by Real Time 3D Echocardiography

The presented case reports on successful treatment with everolimus in a neonate with left ventricular giant rhabdomyoma. The authors used a different dosage regime compared to literature and documented rapid tumor regression by 3D echocardiography.     

Transient left bundle branch block after posture change to the prone position during general anesthesia: A case report

Rationale:The prone position is commonly used in spinal surgery. There have been many studies on hemodynamic changes in the prone position during general anesthesia. We report a rare case of transient left bundle branch block (LBBB) in a prone position.Patient concern:Electrocardiogram (ECG) of a 64-year-old man scheduled for spinal surgery showed normal sinus rhythm change to LBBB after posture change to the prone position.Diagnosis:Twelve lead ECG revealed LBBB. His coronary angio-computed tomography results showed right coronary artery with 30% to 40% stenosis and left circumflex artery with 40% to 50% stenosis. The patient was diagnosed with stable angina and second-degree atrioventricular block of Mobitz type II.Intervention:Nitroglycerin was administered intravenously during surgery. Adequate oxygen was supplied to the patient. After surgery, the patient was prescribed clopidogrel, statins, angiotensin II receptor blocker, and a permanent pacemaker was inserted.Outcome:Surgery was completed without complications. After surgery, the transient LBBB changed to a normal sinus rhythm. The patient did not complain of chest pain or dyspnea.Lesson:The prone position causes significant hemodynamic changes. A high risk of cardiovascular disease may cause ischemic heart disease and ECG changes. Therefore, careful management is necessary.     

组织多普勒成像评价左房收缩功能的临床研究

目的应用多普勒组织成像技术测定61名健康成人二尖瓣环运动峰值速率(Am),以评价Am在左房收缩功能中的价值。方法观察61名无心脏疾患者的Am,Am值为二尖瓣前、后、左、右侧心房收缩期二尖瓣环运动峰值速率的平均值;并与左房收缩时左房面积改变分数(FAC)和容积改变分数(FVC)作相关性研究。结果61例研究对象平均FAC和FVC分别为(31±10)%和(42±11)%;Am为(13.4±3.2)cm/s;直线回归分析显示,Am与FAC和FVC均呈正相关(r=0.78和0.82;P均<0.001)。结论Am与FAC、FVC具有良好相关性,从而为临床评价左房收缩功能提供了一种简便而快速的方法。     

环状软骨前裂开对兔环状软骨生长发育的影响

目的:观察环状软骨前裂开对环状软骨生长发育的影响。方法:将幼兔环状软骨前正中裂开,8月后测量环状软骨内径,计算其管腔面积。结果:(1)与对照组比较,实验组兔环状软骨管腔面积无显著性差异(P>0.05)。(2)裂开处均由软组织连接,未形成过多瘢痕。结论:环状软骨前裂开对环状软骨及动物的生长发育无明显影响。     

Cardiac myxoma with glandular component: case report

Cardiac myxoma has varying clinical presentation, uncertain histogenesis and debatable immunohis- tochemical profile. Glandular epithelial differentiation is a rare phenomenon, but glandular elements are known to be present in cardiac myxoma as an intrinsic component of the tumor. We present a case of cardiac myxoma having focal glandular differentiation, with special reference to the morphologic features and immunohistochemical profiles.     

Female pelvic floor. Descriptive anatomy and clinical exploration by transvaginal ultrasound

In order to assess the state and pathology of the woman's pelvis minor, a number of methods are commonly used among practitioners, encompassing clinical exploration, radiology, MRN, urodynamics, endoscopy and echography.

Echography has been poorly used in clinical pelvic exploration and its reliability is actually a matter of controversy 1. However, echographic surveys can provide us with valuable gynecological data on the state and pathologies of the soft pelvis, within the genital regions or even going beyond them, i.e. the rectal channel, bladder, urethra, anus, vascular plexuses, and all of their supporting tissues.

At our research unit, we have been employing Transvaginal Ultrasound echography (TVU) for a long time in conjunction with other pelvis-focused methods in order to study different kinds of pelvic alterations. TVU has proven to be friendly to use, fast, harmless and inexpensive, allowing serial explorations and producing high-quality dynamic images (loop-cinema, video-tape). Furthermore, this method is fairly aseptic in that the occurrence of faeces in the rectal ampolla is not a nuisance but a bonus in tracking the contours of the rectum walls and other topographical features which would be otherwise difficult to survey.

A complete pelvic floor TVU may add no longer than 5-8 minutes to a routine gynecological examination, can be implemented by the general gynecologist and generates data that can be further studied by the appropriate specialist for a more insightful evaluation 2.
