Update on sports imaging

Sports Imaging has dramatically increased in the past decade with increasing number of adolescents, young and middle-aged adults participating in non-competitive/hobby sports. Therefore, sports injuries are no longer confined to elite athletes. Furthermore, newer forms of sports such as mountain climbing, pickle ball and curling etc. are gaining popularity. Majority of the injuries in sports medicine are from musculoskeletal trauma. Therefore, it is imperative that the musculoskeletal radiologist becomes familiar with various sports related injury patterns as these are commonly encountered in daily practice. This update aims to briefly encapsulate the major aspects of sports imaging. It includes the imaging manifestations of various types of musculoskeletal injuries on different modalities (commonly US and MRI) and briefly mentions the various image guided interventions, performed both on the sports field and in the hospital setting.     

Role of surgical treatments in high-grade or advanced gastroenteropancreatic neuroendocrine neoplasms

Over the last 40 years, the incidence and prevalence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) have continued to increase. Compared to other epithelial neoplasms in the same organ, GEP-NENs exhibit indolent biological behavior, resulting in more chances to undergo surgery. However, the role of surgery in high-grade or advanced GEP-NENs is still controversial. Surgery is associated with survival improvement of well-differentiated high-grade GEP-NENs, whereas poorly differentiated GEP-NENs that may benefit from resection require careful selection based on Ki67 and other tissue biomarkers. Additionally, surgery also plays an important role in locally advanced and metastatic disease. For locally advanced GEP-NENs, isolated major vascular involvement is no longer an absolute contraindication. In the setting of metastatic GEP-NENs, radical intended surgery is recommended for patients with low-grade and resectable metastases. For unresectable metastatic disease, a variety of surgical approaches, including cytoreduction of liver metastasis, liver transplantation, and surgery after neoadjuvant treatment, show survival benefits. Primary tumor resection in GEP-NENs with unresectable metastatic disease is associated with symptom control, prolonged survival, and improved sensitivity toward systemic therapies. Although there is no established neoadjuvant or adjuvant strategy, increasing attention has been given to this emerging research area. Some studies have reported that neoadjuvant therapy effectively reduces tumor burden, improves the effectiveness of subsequent surgery, and decreases surgical complications.     

Place et modalités de l’irradiation postopératoire dans la prise en charge des métastases cérébrales

Metastases are the most common brain tumors. After surgery, stereotactic radiotherapy (SRT) of the resection cavity is the standard of care. Data from two randomized trials indicate that SRT to the surgical bed is an effective treatment in reducing local failure as compared with observation, while reducing the risk of cognitive deterioration and maintaining quality of life as compared with whole brain radiation therapy. Local control appears higher after hypofractionated SRT compared to single-fraction SRT. Several questions such as target volumes, the optimal regimen in particular for large tumor bed, strategies to reduce the risk of lepto-meningeal recurrence, and the treatment sequence still need to be answered.     

儿童期创伤应对方式自动思维与大学生抑郁特质间的关系

目的探讨儿童期创伤与抑郁特质之间的中介和调节机制,为开展相关研究和干预提供参考。方法2017-2018年采用整群抽样的方法,抽取湖南某高校大一年级2 786名学生完成儿童期创伤问卷、状态特质抑郁问卷、自动思维问卷和特质应对方式问卷的调查。结果儿童期创伤、自动思维和消极应对对抑郁特质起正向的预测作用,积极应对对抑郁特质起负向的预测作用(β值分别为0.12,0.43,0.14,-0.33,P值均<0.05)。自动思维中介儿童期创伤与抑郁特质之间的关系(Bootstrapping法的95%CI为0.03~0.06)。消极应对分别调节了儿童期创伤与自动思维和儿童期创伤与抑郁特质之间的关系(P值均<0.05)。结论儿童期创伤影响抑郁特质,其关系受到应对方式和自动思维的影响。

单孔胸腔镜手术在结核性脓胸治疗中的应用

目的探讨单孔胸腔镜手术治疗结核性脓胸的应用价值,并总结相关临床经验。方法回顾性分析我院胸外科2015年1月～2017年12月住院手术治疗的120例结核性脓胸患者。依据纳入、排除的相关标准,在知情同意下将纳入患者随机分为研究组(单孔胸腔镜手术组,60例)和对照组(传统开胸手术组,60例),比较两组患者的手术时间、术中出血量、术后引流量、胸腔引流管时间、术后住院时间及术后并发症。结果两组患者围术期均无死亡病例,中转开胸3例,中转开胸率为5%(3/60)。单孔胸腔镜组与传统开胸组相比较,手术时间分别为(88.00±15.77)min、(87.52±15.66)min,术中出血量分别为(236.33±15.16)mL、(443.75±43.69)mL,术后引流量分别为(423.93±41.49)m L、(663.92±16.28)mL,胸腔引流管时间分别为(2.92±0.10)d、(4.35±1.44)d,术后住院时间分别为(11.50±2.51)d、(13.65±2.52)d,两组患者的术中出血量、术后引流量、胸腔引流管时间及术后住院时间相比,差异均有统计学意义(P均0.05)。比较两组的手术时间,差异无统计学意义(P0.05)。单孔胸腔镜组术后并发症的总的发生率为6.67%(4/60),传统开胸组术后并发症的总发生率为13.33%(8/60)。结论单孔胸腔镜手术治疗结核性脓胸创伤小、并发症少、住院时间短,患者恢复快,在临床应用中值得推广。但在临床实际中应根据患者病情合理选择手术方式。     

Subacute cutaneous lupus erythematosus leukoderma treated with melanocyte‐keratinocyte transplantation procedure

Depigmented lesions may occur as postinflammatory sequelae of subacute cutaneous lupus erythematosus (SCLE), leading to great psychosocial impact. A 53‐year‐old male patient presented with post‐SCLE depigmented facial lesions after five years of disease stability. We proposed surgical treatment with melanocyte‐keratinocyte transplantation procedure (MKTP), and after five months the patient achieved 90% repigmentation, without Koebner phenomenon (KP). In theory, KP is a possible complication of MKTP procedure since the preparation of the receptor area involves the use of dermabrasion. In an attempt to avoid it, we suggest to maintain the treatment of the underlying disease and wait for a minimum period of disease stability before the procedure.
