Gastric Barotrauma in a Scuba Diver: Report of a Case

Stomach rupture can occur as a consequence of the expansion of compressed air during rapid ascent after diving. We present the case of a middle-aged woman who suffered a gastric tear from surfacing too quickly after diving, and discuss the diagnosis and management of such patients by reviewing previously reported similar events. Gastric barotrauma should be suspected in divers who complain of abdominal pain, even in the absence of frank signs of peritoneal irritation. Although pneumoperitoneum is always present in these patients, it can also occur as a consequence of pulmonary barotrauma, making gastroscopy or radiological contrast studies, or both, essential for a definitive diagnosis. Surgical repair represents the treatment of choice for an active full-thickness tear and, if associated with arterial gas embolism or decompression sickness, should ideally be performed in a center where a category I (intensive care-capable) hyperbaric unit is available.

病变椎体切除脊柱稳定性重建治疗胸腰椎转移瘤

目的:探讨病变椎体切除脊柱稳定性重建治疗胸腰椎转移瘤可行性与临床价值。方法:1999年7月-2006年4月,采用后正中加后外侧"T"形切口行病变椎体切除、钛网 切除的肋骨或取自体髂骨填充植骨、椎弓根钉棒系统内固定治疗16例胸腰椎转移瘤患者,随访观察患者术后局部疼痛缓解、脊髓神经功能恢复及脊柱稳定性情况。结果:术后患者腰背痛及放射性疼痛基本缓解,均于术后早期开始肢体功能锻炼,术后2-3周离床活动。随访8个月-3年,患者神经系统压迫症状明显改善,3例C级患者2例恢复到D级,1例恢复到E级;D级5例均恢复到E级。影像学复查内固定物无松动、断钉、断棒现象,钛网无移位,椎体无塌陷。结论:经后正中加后外侧"T"形切口手术切除病变椎体并重建脊柱的三柱稳定性结构治疗胸腰椎转移瘤是可行的,可提高患者生存期内的生活质量。     

An internet survey of 2,596 people with fibromyalgia

Background  

This study explored the feasibility of using an Internet survey of people with fibromyalgia (FM), with a view to providing information on demographics, sources of information, symptoms, functionality, perceived aggravating factors, perceived triggering events, health care utilization, management strategies, and medication use.     

Acute Achilles tendon rupture: minimally invasive surgery versus non operative treatment,with immediate full weight bearing. Design of a randomized controlled trial

Background  

We present the design of an open randomized multi-centre study on surgical versus conservative treatment of acute Achilles tendon ruptures. The study is designed to evaluate the effectiveness of conservative treatment in reducing complications when treating acute Achilles tendon rupture.     

CT导引下胸部病变穿刺活检不同方法的临床探讨

目的探讨胸部病变穿刺活检联合同轴针吸对提高阳性率减少并发症的价值。方法回顾性分析CT导引下106例胸部病变三种不同穿刺方法的阳性率及并发症。结果单纯针吸组32例,检出恶性病变23例,良性4例,阳性率为84.3%,并发症为15.6%;单纯活检组27例,检出恶性病变15例,良性7例,阳性率为81.5%,并发症为48.1%;活检同轴针吸组47例,检出恶性病变28例,良性15例,阳性率91.5%,并发症为29.7%。结论活检联合同轴针吸是提高阳性率减少并发症的较好的活检方法,它既弥补了活检的缺点,又集中了针吸的优点,是值得推广的活检方法。     

The Role of Extended Lymphadenectomy for Adenocarcinoma of the Head of the Pancreas: Strength of the Evidence

With improvements in the safety of Whipple resection in recent decades, surgeons have continued to explore the role of more extensive lymphadenectomy in hope of improving long-term survival. A systematic literature search of level I evidence addressing the role of the extent of lymphadenectomy was undertaken. Only reports of prospective, randomized controlled trials comparing pancreaticoduodenectomy with standard lymphadenectomy to pancreaticoduodenectomy with extended lymphadenectomy where information regarding survival, morbidity, mortality, the number of resected lymph nodes in each group and detailed operative technique were included. Four prospective, randomized trials comprising some 424 patients and one meta-analysis were identified. In aggregate, these studies confirmed that the number of resected lymph nodes was significantly higher in the pancreaticoduodenectomy with extended lymphadenectomy group. Morbidity and mortality rates were comparable. Postoperative diarrhea in the early months after operation was problematic in patients undergoing extended lymphadenectomy. In none of the studies was a benefit in long-term survival demonstrated. Standard pancreaticoduodenectomy continues to be the operation of choice for adenocarcinoma of the head of the pancreas.
