Bilateral cervical spondylolysis in a young Chinese woman presenting with a neck injury

Cervical spondylolysis is an uncommon entity. It is important to recognise its characteristic radiological features and differentiate it from acute cervical fractures or dislocations in patients with neck injuries. We report the relevant clinical and radiological findings seen in a young Chinese woman managed in our hospital after a neck injury who was ultimately diagnosed with bilateral cervical spondylolysis with spondylolisthesis at C6.     

A large left ventricular calcification presenting with ventricular tachycardia

To the editor:A-51-year old male with no relevant medical history was admitted to our department due to palpitation lasting for a few months.Duration of tachycardia was 1-2 minutes and resulting with presyncope.Physical examination and laboratory tests were normal,blood pressure measured as 115/60 mmHg (1mmHg=0.133 kPa) and the heart rate was 85 beats per minute.     

A young patient with history of Kawasaki disease presenting with triple vessel disease

Kawasaki disease is primarily a condition that affects young children and it is associated with cardiac morbidity and mortality. This disease has been known to cause coronary artery aneurysms which occurs as a sequelae of vasculitis. The progression of triple vessel disease in adult which results from cardiac complications from Kawasaki disease is rare. We report a case of a young man with history of Kawasaki disease at infancy presenting with triple vessel disease requiring cardiac bypass surgery at the age of 20 years old.     

Carcinoma of the sigmoid colon presenting as a scrotal swelling.

A case of adenocarcinoma of the sigmoid colon, presenting as a testicular mass, is described. At sigmoid colectomy widespread metastases were found and only palliative care could be offered thereafter. The incidence and age of such a presentation and manner of spread of the occult primary are discussed.     

面、颈部瘢痕挛缩三种修复方法疗效比较

目的: 观察面、颈部瘢痕挛缩三种修复方法的疗效。方法: 23例灼伤后面、颈部瘢痕挛缩患者,瘢痕面积在6 cm×5 cm~16 cm×9 cm,根据具体情况,分别采用"Z"成形术、植皮术及扩张器扩张后皮瓣修复术治疗。结果: 采用以上三种方法,术后患者的外观及功能得到较大改善,效果满意。结论: 以上三种手术方法,可根据患者情况分别予以使用,各有其优缺点,均为临床可供选择的手术治疗手段。     

双酚A对雄性仔鼠生殖功能的影响

目的：探讨双酚A对雄性仔鼠生殖功能的影响。方法：妊娠小鼠随机分成4组，从受孕第1天起实验组分别以30、120和360 mg•kg^-1•d^-1剂量溶于玉米油中的双酚A染毒至仔鼠出生，对照组用相同体积玉米油灌胃。仔鼠出生30 d后检测各组雄性仔鼠精子畸形率、睾丸乳酸脱氢酶(LDH)和6-磷酸葡萄糖脱氢酶(G-6-PD)、脏体比及病理组织学改变。结果：实验组小鼠睾丸曲细精管上皮细胞排列紊乱、成熟精子数量减少，部分上皮与基底部分离，且随剂量增加而加重；与对照组比较，低、高剂量组脏器系数降低，中、高剂量组LDH活性、G-6-PD活性降低，低剂量组LDH活性升高；随剂量增加精子畸形率增高，差异均具有显著性(P<0.01)。结论：胚胎期接触双酚A对F1代雄性仔鼠的生殖功能产生影响。     

腹前壁下部的定态观测

目的：找出腹前壁下部的三角形，方法：采用成人活体样本500例，用产科骨盆测量器测量了腹前壁的脐、两髂前上棘（髂棘点）及耻骨联合上缘中点（耻上点）四点之间长度，探讨和各点之间连线的形态关系。结果：由于这四点之间的连线方式不同，可得到脐棘三角，耻棘三角，左、右脐棘耻三角，并发现这些三角形有等腰三角形，任意三角形和等边三角形，而这些三形在人群瘦人型，适中型和矮胖型各种体型中都有分布。结论：经统计学处理，对积累国人体质调查资料，有一定的临床研究参考价值。     

采用超声探测颈侧前部的临床意义

目的探讨颈前椎间盘平面颈动脉鞘和食管的超声影像图及在指导颈椎手术的临床意义。方法采用体表超声检查30例正常成人颈部双侧前方椎间盘平面颈动脉鞘与食管间的关系、走向位置、解剖距离等超声影像图特征。结果颈前超声可清晰探测颈椎间盘、颈动脉鞘、食管及其之间的位置关系。颈部食管在颈椎前方下行中逐渐由中线偏向左侧移行,在各颈椎间盘平面,颈动脉鞘与食管间距离右侧大于左侧。结论颈前右侧颈动脉鞘与食管间距离较左侧更大。为避免食管损伤,在行椎间盘微创穿刺或手术操作中,与左侧入路相比,右侧入路是个相对更安全的操作路径。     

Effort thrombosis in a young triathlete: an unusual presentation of painless neck swelling secondary to right brachiocephalic vein thrombosis

Effort thrombosis of the upper extremity is secondary to thrombosis of the axillary and/or subclavian veins that develop from heavy arm exertion. This case illustrates venous thrombosis of the right brachiocephalic vein in a 32-year-old man who presented with a cyst-like swelling in the right neck with no associated pain or trauma. Our patient, a trained athlete, was preparing for a triathlon at the time of presentation. He was treated by first-line therapy of subcutaneous and oral anti-coagulation medication. In this study, we highlight the importance of early investigation and treatment of symptomatic athletes so that long-term disability can be prevented. This study also shows the timely use of computed tomography imaging, which can help to identify the syndrome in previously undiagnosed patients.     

无栓病房建立对下肢骨折患者术后患肢肿胀及预后的影响

目的探讨无栓病房建立对下肢骨折患者术后患肢肿胀及预后的影响。方法采用简单随机抽样法抽取2016年3月至2017年2月的300例下肢骨折患者设为对照组,按照下肢骨折围手术护理常规实施护理; 2017年3月至2018年5月的300例患者设为观察组,在对照组常规护理基础上建立无栓病房及管理,观察比较两组患者术后第7天患肢肿胀的疗效及入院时、术后第1天、第3天、第7天患肢周径和疼痛状况。结果术后第7天,观察组患肢肿胀疗效优于对照组,术后第1天、第3天、第7天患肢周径和数字化疼痛评估法(NRS)评分观察组均低于对照组,差异有统计学意义(P<0.01)。结论无栓病房建立能减轻下肢骨折患者术后患肢肿胀和疼痛的程度,提高患肢肿胀的疗效。
