Heart rupture as an acute complication of cocaine abuse: A case report

The purpose of this study is to show a very rare complication of acute cocaine poisoning, namely heart rupture. In the present case report, acute cocaine intoxication caused massive myocardial infarction, resulting in heart rupture and cardiac tamponade. A crime scene investigation found a dead body on the street in a drug dealing district. Examination of the body showed no external injuries. A thorough autopsy was performed showing massive cardiac tamponade with 510 ml of blood within the pericardium and full-thickness tissue lesion at the posterior wall of the left ventricle of 3.5 × 3 cm. Histological examination in hematoxylin and eosin was performed and confirmed the interruption of the posterior wall of the left ventricle with the presence of blood. In fact, although the correlation between cocaine and myocardial damage is well established, the relationship between heart rupture and acute cocaine intoxication is an extremely rare event. Moreover, since there are, to date, few reports of similar deaths, our report provides useful information regarding sudden death in a cocaine abuser. It is, therefore, of crucial importance to report this case to the scientific community.     

The danger of chlorhexidine in lignocaine gel: A case report of anaphylaxis during urinary catheterisation

This article describes a case of anaphylaxis secondary to chlorhexidine during urethral catheterisation. Despite little evidence for the use of antiseptic lubricants in preventing catheter-associated urinary tract infections, the distribution and use of such products continues to be widespread. Chlorhexidine-free lubricating gel is widely available and should be used for urological procedures wherever possible.     

直丝弓矫治器和Begg矫治器治疗安氏Ⅱ类1分类错[牙合]畸形疗效比较

目的:对比不同矫治器对错[牙合]畸形患者面高度及前后牙咬合关系的影响。方法:选取于笔者医院接受矫治的83例错[牙合]畸形患者,根据患者矫治器类型分为直丝弓组和Begg组,分别为42例和41例。比较并分析两组患者治疗前后牙咬合关系、硬组织、磨牙及面高度的变化情况。结果:矫治后,两组患者OJ-PPV、OB-PP、LMA-MPV、LMA-MPV均降低,Begg矫治组OJ-PPV水平显著高于直丝弓矫治组,OB-PP、LMA-MPV、LMA-MPV水平显著低于直丝弓矫治组,差异均具有统计学意义(P<0.05);两组患者LAFH、LAFH/TAFH、PFH/TAFH水平均升高,其中Begg矫治组患者LAFH水平显著低于直丝弓矫治组,差异均具有统计学意义(P<0.05);两组患者LMA-MP、LMC-MP水平均升高,差异具有统计学意义(P<0.05);矫治前后,两组患者SNA、SNA、ANB水平均无统计学差异(P>0.05)。结论:两种矫治器对错[牙合]畸形患者硬组织变化均无明显影响,其中Begg矫治对患者前后牙咬合关系改善作用更强,直丝弓对患者面高度的改善能力更强。     

Isolated Anisocoria as a Presenting Stroke Code Symptom is Unlikely to Result in Alteplase Administration

Background

Acute stroke codes may be activated for anisocoria, but how often these codes lead to a final stroke diagnosis or alteplase treatment is unknown. The purpose of this study was to assess the frequency of anisocoria in stroke codes that ultimately resulted in alteplase administration.

胎膜早破孕妇生殖道感染情况及对妊娠结局影响

目的 研究胎膜早破孕妇生殖道感染情况及对妊娠结局的影响。方法 选择2014年5月至2015年1月住院分娩的胎膜早破孕妇70例为早破组,同期无胎膜早破70例为对照组,检测两组生殖道病原微生物感染情况,并比较两组的妊娠结局。结果 早破组生殖道感染阳性率高于对照组,且剖宫产率,母体发生产后出血,绒毛膜羊膜炎,胎儿窘迫及新生儿窒息发生率均高于对照组,差异均有统计学意义(P<0.05)。结论 生殖道感染是胎膜早破最常见的诱因,积极筛查及治疗孕妇生殖道感染可以减少相关产科并发症的发生。     

关节镜下TightRope治疗后交叉韧带撕脱骨折

目的探讨关节镜下使用TightRope治疗后交叉韧带(PCL)撕脱骨折的技术应用和临床疗效。方法 12例膝关节PCL撕脱骨折患者在关节镜下使用TightRope固定PCL撕脱骨块。术后1周开始在支具保护下被动活动膝关节,术后10个月评估膝关节功能恢复情况。结果 12例患者均获随访,时间10～14个月,平均12.6个月,骨折均Ⅰ期愈合。1例屈膝受限15°,无伸膝受限;2例后抽屉试验(+)。Lysholm膝关节功能评分术前(45.6±6.3)分,术后10个月(87.8±4.8)分,差异有统计学意义(P 0.05)。结论关节镜下使用TightRope治疗PCL撕脱骨折固定可靠,操作相对简单,疗效满意。     

脾保留手术治疗创伤性脾破裂的临床探讨

目的：分析脾保留手术治疗创伤性脾破裂的疗效。方法选取该院2011年6月—2014年6月收治的创伤性脾破裂患者，共计56例，分为两组，各28例，对照组进行脾切除手术，研究组进行脾保留手术。结果研究组临床有效率为92.86%，对照组临床有效率为78.57%；术后并发症发生率研究组为10.71%、对照组为28.57%。结论脾保留手术治疗创伤性脾破裂的疗效显著，恢复快，并发症少，在患者伤情允许情况下优先选择脾保留术。
