Peyronie’s disease: Contemporary evaluation and management

Peyronie’s disease is a common yet poorly understood condition characterized by penile pain, curvature, sexual dysfunction and psychological bother. Peyronie’s disease represents a penile wound healing disorder, and is thought to arise from exuberant scarring in response to penile trauma in genetically predisposed men. In the absence of active treatment, the majority of men experience stable or worsening symptoms, with few reporting spontaneous resolution in penile curvature or other deformity. In contrast, penile pain improves or resolves in the majority of men. Treatment options vary based on symptom severity and stability. Several oral therapies are commonly prescribed, although to date there are no strong data to support any oral agents as monotherapy for Peyronie’s disease. Other options including penile traction therapy and intralesional injections result in modest improvements for many patients, particularly when used early after symptom onset. Penile straightening through approaches, such as penile plication and plaque incision or partial excision and grafting, represent the most rapid and reliable approach to correct penile curvature once the symptoms have stabilized. Side-effects vary based on the type of surgery carried out, and include penile shortening, sensation changes and erectile dysfunction in the minority of men. In patients with drug refractory erectile dysfunction and Peyronie’s disease, placement of a penile prosthesis will address both issues, and is associated with high levels of patient satisfaction. The current review provides a practical approach to the modern evaluation and management of patients presenting with Peyronie’s disease.

Distribution patterns of transforaminal injections in the cervical spine evaluated by multi-slice computed tomography

Transforaminal injections are sometimes used for the diagnosis and treatment of painful conditions in the lumbar and to a lesser degree in the cervical spine. The technique is most often used when investigating/treating radiculopathy caused by degenerative disease. But how selective are the nerve root blocks? What possible structures other than the intended nerve root are affected from such injections? This study was undertaken in order to try to answer these questions, as no study focusing on the possible spread from the transforaminal selective nerve root blocks in the cervical spine has been performed earlier. In three groups of patients, each group including three patients, we injected three different volumes (0.6, 1.1 and 1.7 ml) with a transforaminal technique in the cervical spine. In all the injections, a small amount of contrast media was added. The spread of the injections were then investigated using multi-slice computed tomography with reconstructions. The imaging revealed a possible effect on other nerve roots than the intended ones when a larger volume was used for the root blocks. The spread was related to the injected volume as well as to local anatomy (size of foraminal area). In this study, only 0.6-ml injections could be accepted for being selective enough for diagnostic investigations.     

项韧带骨化相关因素及其组织学变化

目的：探讨脊髓型颈椎病患者项韧带骨化的相关因素及其组织学改变特点.方法：将45例脊髓型颈椎病患者根据项韧带有无骨化分为两组,观察并统计两组患者的年龄、性别组成、颈椎椎间退变和颈椎稳定性情况,对各指标与项韧带骨化的关系进行相关性分析,同时观察项韧带骨化的组织学改变.结果：统计分析表明,项韧带骨化和颈椎椎间退行性改变及颈椎不稳定之间具有相关性（P＜0.05）;同时还与患者年龄、性别组成有相关性（P＜0.05）.项韧带骨化的组织学改变以软骨内化骨为主.结论：项韧带骨化与颈椎退行性改变及颈椎椎间关节不稳定具有相关性,组织学改变以软骨内化骨为主.     

颈椎前路手术内置物并发症的分析

导航系统辅助下颈椎椎弓根螺钉置钉准确性的实验研究

目的：评价导航系统辅助下颈椎（C3～C7）椎弓根螺钉内固定置钉的准确性.方法：将32具成人尸体颈椎标本随机分为4组,分别采用盲法、透视法、透视导航法和CT导航法进行下颈椎椎弓根螺钉置入.术后采用标本大体解剖观察的方法评价置钉准确性.分优（螺钉完全在椎弓根内）、可（仅有螺纹穿出,对周围组织无损伤）和差（螺钉明显穿出）进行统计.结果：共置入螺钉318枚.盲法80枚,平均手术时间27min,优29枚（36 3%）、可21枚（26.3%）、差30枚（37.5%）;透视法78枚（有1例C4、C5右侧椎弓根均细小,不能容纳3.5mm螺钉）,平均手术时间112min,优35枚（44.9%）、可29枚（37.2%）、差14枚（17.9%）;透视导航法80枚,平均手术时间69min,优34枚（42.5%）,可36枚（45%）,差10枚（12.5%）;CT导航法80枚,平均手术时间98min,优70枚（87.5%）、可10枚（12.5%）.各组间手术时间均有显著性差异（P＜0.05）,透视法与透视导航法的置钉准确率间无显著性差异,其余各组间均有显著性差异（P＜0.05）.结论：单纯根据术前影像结果盲法行下颈椎椎弓根螺钉内固定不安全.透视法和透视导航法可提高置钉准确性,但手术风险仍较大,透视导航法比透视法置钉的手术时间缩短.CT导航法并未比透视法增加手术时间,但置钉准确性显著提高.
