Round one of the Adelaide and Meath Hospital/Trinity College Colorectal Cancer Screening Programme: programme report and analysis based on established international key performance indices

Background  

In Ireland, colorectal cancer (CRC) is the second most frequently diagnosed cancer in men, after prostate cancer, and the second most frequently diagnosed cancer in women, after breast cancer. By 2020, the number of new cases diagnosed annually in Ireland is projected to have increased by 79% in men and 56% in women. Organised screening for CRC is already underway or is in the process of being rolled out in several European countries, either at a regional or national level. The Adelaide and Meath Hospital/ Trinity College Dublin Colorectal Cancer Screening Programme (TTC-CRC-SP) is Ireland’s first pilot population based bowel screening programme.     

Carto XP/Cart03与常规标测指导下消融特发性右室流出道室性早搏的比较

目的 比较常规电生理标测与三维电解剖标测系统(Carto XP/Carto3)标测指导下行导管射频消融治疗特发性右室流出道室性早搏(right ventricular outflow tract premature ventricularcontraction,RVOT-PVC)的有效性和安全性.方法 分析2013年3月至2015年10月于我科进行射频消融治疗的144例室早病例:36例室早患者采用常规电生理标测指导下射频消融(常规组),108例室早采用Carto XP/Carto3标测指导下射频消融(Carto XP/Carto3组).从靶点标测、消融、术中X线曝光以及手术总耗时等时间方面对两种标测方法进行比较;检测两组术前及术后1d和3dC反应蛋白(C reactive protein,CRP)、血清肌钙蛋白Ⅰ(serum cardiac troponin Ⅰ,cTn Ⅰ)和磷酸肌酸激酶同工酶(creatine kinase-MB,CK-MB)的变化,观察随访疗效.结果 Carto XP/Carto3组在室早靶点标测、成功消融、X线曝光以及手术总时间方面均较常规电生理标测组明显缩短(P＜0.01),心肌损伤指标CRP、cTn Ⅰ和CK-MB均明显降低(P＜0.01);两组的即刻成功率分别为94.4％ (34/36)和100％ (108/108),差异有统计学意义;术后1个月随访时,常规组即刻成功的34例患者中有3例室早复发,Carto XP/Carto3组无复发病例.术后3个月时,两组均无新的复发病例.结论 Carto XP/Carto3标测指导的消融靶点定位更精准,手术安全性及有效性更好;常规电生理标测指导的射频消融仍具有较高成功率,手术费用相对便宜,为经济困难而又确实需要消融治疗的患者提供了一种可行的选择方案.     

3.0T高场强术中磁共振在功能区动静脉畸形手术中的应用:初步研究

目的：探讨高场强术中磁共振（iMRI）引导功能区动静脉畸形（AVM）手术的临床价值。 方法：术前根据病变部位行血氧水平依赖功能磁共振（BOLD-fMRI）、弥散张量成像(DTI)等定位功能皮层及皮层下神经传导束,行头颅液体衰减翻转恢复（FLAIR）及时间飞跃磁共振血管成像（TOF-MRA）扫描并三维重建、观察畸形团与周围脑组织的位置关系。所有病人在导航引导下设计手术切口、引导手术切除AVM;预计达术前手术计划时行iMRI扫描,包括FLAIR、MRA、BOLD-fMRI、DTI、灌注加权成像（PWI）序列。术后随访CT血管成像（CTA）、数字剪影血管成像（DSA）及患者的神经功能。 结果：7例邻近功能区的AVM患者被纳入该研究。每例患者MRA 清晰显示AVM血管结构,与FLAIR结构影像及功能影像相融合,显示畸形团与周围脑组织、脑功能区之间的位置关系。所有病例均在iMRI导航及神经电生理监测（IONM）下行AVM切除,无iMRI及IONM等引起的技术故障。每例病例术中MRA判断AVM全切除。术后5例复查DSA,2例复查CTA,结果证实术中判断。1例术中PWI发现畸形团残腔后界高灌注,术后2天出血;所有患者恢复好,无新发神经功能障碍或加重。 结论：iMRI辅助功能区AVM手术,有助于术前制定手术计划,引导手术进程;有助于术中发现残留畸形团,保护重要脑功能区,早期发现脑出血等并发症。     

Human myiasis in western Jamaica: five years after the implementation of a screwworm eradication programme

OBJECTIVE: To determine the distribution of cases of human myiasis admitted to the Cornwall Regional Hospital (CRH), Jamaica, between 1999 and 2003, following the inception of the National Screwworm Eradication Programme (NSEP) in 1998, and the risk factors associated with the condition. METHOD: A total of 144 cases of myiasis were retrieved from the database of the department of Medical Records at the CRH for the years 1999 to 2003. A data extraction form was devised to review the circumstances of each case. The data were analyzed using EpiInfo version 6. RESULTS: Of 144 cases, 54.9% were female and 45.1% male. The largest groups were < 10 years, 52.8% [76/144 (M-21, F-55)] and 60years and over, 18.8% [27/144 (M-16, F-I)] (p < 0.001). Case distribution for the years 1999-2003 showed 16, 39, 31, 30, and 28 cases respectively. Three-quarters (74.6%) of all cases affected the scalp/head one-fifth (20.3%) affected the lower limbs. Ninety-six per cent of those < 10 years had scalp/head myiasis (p < 0.001; OR = 23.29; CI: 6.14 < OR < 104.11). Two-thirds (66.6%) of those 60 years and over had lower limb myiasis (p < 0.001; OR = 19.09; CI: 6.20 < OR < 61.12). Mean duration of treatment was 3.5 days (SD = 1.4 days) and 69.7% required hospitalization for seven or more days. There was no difference in duration of treatment for myiasis or in length of hospitalization in relation to method used to eliminate maggots. Risk factors identified included Tinea capitis for myiasis of the scalp/head (p < 0.001) and diabetes mellitus for lower limb myiasis (p < 0.001; OR = 14.48; CI: 2.37 < OR < 133.25). CONCLUSION: Human myiasis remains a public health issue in western Jamaica with no significant decreasing trend in the number of cases admitted to the CRH since 1999. It is recommended that this zoonosis become a Class 1 notifiable disease to the Ministries of Health and Agriculture because of the existing NSEP.
