Right iliac bone pathological fracture mimicking acute appendicitis

Simple bone cyst (SBC) also known as unicameral bone cyst is a benign, radiolucent bone lesion that is seen commonly in childhood. These lesions are usually found incidentally although pain and swelling can be seen. The most common complication is a pathological fracture, and this is often the cause of presentation. Here, we present a 22-year-old male with right lower quadrant pain due to SBC related pathological fracture of right iliac bone which is mimicking acute appendicitis.     

Th1/Th17/Th22 immune response and their association with joint pain,imagenological bone loss,RANKL expression and osteoclast activity in temporomandibular joint osteoarthritis: A preliminary report

It is well accepted that the presence of cytokines belonging to the Th1/Th17/Th22 axis of immuno‐inflammatory response in the joint environment, such as IL‐1β, IL‐17 and IL‐22, respectively, are associated with pathogenesis of several synovial joint degenerative disorders. During temporomandibular joint osteoarthritis (TMJ‐OA), IL‐1β and IL‐17 have been implicated in the inflammation and resorption of sub‐chondral bone; however, the role of Th22 response in the TMJ‐OA pathophysiology has not been established. This study aimed to compare the expression of Th1/Th17/Th22‐type cytokines, chemokines and chemokine receptors in synovial fluid samples obtained from TMJ‐OA or disk displacement with reduction (DDWR) patients. In addition, it aimed to associate these levels with joint pain, imagenological signs of bone degeneration, RANKL production, osteoclastogenesis and osteoclast‐induced bone resorption. Higher levels of IL‐1β, IL‐17 and IL‐22 were expressed in TMJ‐OA compared with DDWR subjects, and these increased levels significantly correlated with RANKL expression, joint pain and articular bone degeneration. Higher levels of CCR5, CCR6 and CCR7, as well as their respective ligands CCL5 and CCL20, responsible for recruitment of IL‐1β, IL‐17 and IL‐22‐producing cells, were over‐expressed in TMJ‐OA compared with DDWR subjects. Osteoclastogenesis and osteoclast‐induced bone resorption were significantly greater in presence of synovial fluid from TMJ‐OA compared with DDWR subjects. These data demonstrate that cytokines, CCLs and CCRs associated with the Th1/Th17/Th22 axis of immuno‐inflammatory response are involved in TMJ‐OA pathogenesis. These findings suggest that IL‐22 is involved in the RANKL expression in TMJ‐OA, which in turn induces differentiation of osteoclasts and subsequent resorption of sub‐chondral bone.     

去大骨瓣减压颞肌贴敷术治疗大面积脑梗死患者几种护理模式的临床应用效果

目的:对比研究不同护理模式在去大骨瓣减压颞肌贴敷术治疗大面积脑梗死患者临床护理中的应用价值。方法:将襄阳市中心医院收治的120例大面积脑梗死患者随机分为A组、B组、C组,各组40例。A组进行常规护理,B组进行临床护理路径表护理,C组进行循证护理。于3组患者护理干预前后,根据美国国立卫生研究院卒中量表(National Institutes of Health Stroke Scale,NIHSS)评分标准评价患者神经功能缺损程度,并根据格拉斯哥预后分级(Glasgow outcome scale,GOS)评价3组患者预后情况。结果:护理3个月、6个月后,C组患者NIHSS评分低于A组、B组(P<0.05),A组、 B组比较,差异无统计学意义(P> 0.0 5)。在预后良好率,A组、 B组、 C组依次为5 0%、6 2.5%、 8 2.5%, C组高于A组、 B组(P <0.0 5), A组、 B组比较,差异无统计学意义(P> 0.0 5)。结论:于大面积脑梗死患者行去大骨瓣减压颞肌贴敷术治疗中行循证护理能有效提高护理效果,改善患者神经功能缺损程度及预后。     

Cytokine expression profile in the bone‐anchored hearing system: 12‐week results from a prospective randomized,controlled study

Objective

To study the effect of implanting the percutaneous bone‐anchored hearing system (BAHS) itself and inflammation of the peri‐abutment skin warrant clarification. In this study, we aimed to acquire further insight into the immune responses related to BAHS surgery and peri‐implant skin inflammation.

Materials and Methods

During surgery and 12 weeks post‐implantation, skin biopsies were obtained. If applicable, additional biopsies were taken during cases of inflammation. The mRNA expression of IL‐1β, IL‐6, IL‐8, TNFα, IL‐17, IL‐10, TGF‐ß, MIP‐1α, MMP‐9, TIMP‐1, COL1α1, VEGF‐A, FGF‐2 TLR‐2, and TLR‐4 was quantified using qRT‐PCR.

Results

Thirty‐five patients agreed to the surgery and 12‐week biopsy. Twenty‐two patients had mRNA of sufficient quality for analysis. Ten were fitted with a BAHS using the minimally invasive Ponto surgery technique. Twelve were fitted with a BAHS using the linear incision technique with soft‐tissue preservation. Five biopsies were obtained during episodes of inflammation. The post‐implantation mRNA expression of IL‐1β (P = .002), IL‐8 (P = .003), MMP9 (P = .005), TIMP‐1 (P = .002), and COL1α1 (P < .001) was significantly up‐regulated. IL‐6 (P = .009) and FGF‐2 (P = .004) mRNA expression was significantly down‐regulated after implantation. Within patients, no difference between post‐implantation mRNA expression (at 12 weeks) and when inflammation was observed. Between patients, the expression of IL‐1β (P = .015) and IL‐17 (P = .02) was higher during cases of inflammation compared with patients who had no inflammation at 12‐week follow‐up.

Conclusions

As part of a randomized, prospective, clinical trial, the present study reports the molecular profile of selected cytokines in the soft tissue around BAHS. Within the limit of this study, the results showed that 12 weeks after BAHS implantation the gene expression of some inflammatory cytokines (IL‐8 and IL‐1β) is still relatively high compared with the baseline, steady‐state, expression. The up‐regulation of anabolic (COL1α1) and tissue‐remodeling (MMP‐9 and TIMP1) genes indicates an ongoing remodeling process after 12 weeks of implantation. The results suggest that IL‐1β, IL‐17, and TNF‐α may be interesting markers associated with inflammation.     

中医正骨配合外固定架在股骨粗隆间骨折中的应用效果

目的：分析中医正骨配合外固定架在股骨粗隆间骨折治疗中的应用效果。方法我院2010年1月~2012年12月间收治的股骨粗隆间骨折患者104例，按照治疗方案分为对照组和观察组，对照组采用切开复位内固定治疗，观察组采用中医正骨配合外固定治疗，比较两组手术相关指标及疗效。结果观察组手术时间、住院时间明显短于对照组，术中出血量明显少于对照组，差异均具有统计学意义（P＜0.05）；观察组治疗优良率略低于对照组，但两者差异无统计学意义（P＞0.05）。结论中医正骨配合外固定架治疗股骨粗隆间骨折疗效较好，创伤小，且费用较低，临床中应把握好手术适应证、禁忌证及手术时机，以最大限度提高治疗效果。
