Mapping And Ablation Of Complex Cardiac Arrhythmia Guided By A Novel Three Dimensional Non-Contact Endocardial Activation Mapping System, Wing-Hong Fung, Chi-Kin Chan, Kam-Sang Woo, Wilson Wai-Man Chan
Mapping And Ablation Of Complex Cardiac Arrhythmia Guided By A Novel Three Dimensional Non-Contact Endocardial Activation Mapping System, Wing-Hong Fung, Chi-Kin Chan, Kam-Sang Woo, Wilson Wai-Man Chan
Journal of the Hong Kong College of Cardiology
Conventional cardiac activation mapping requires a sequentially-based method of positioning a catheter in contact with the endocardium to generate intracardiac electrograms at single points during sustained arrhythmia. Significant limitation of such point by point mapping may be encountered when applying to complex arrhythmia e.g. non-sustained arrhythmia or haemodynamically unstable arrhythmia. A novel non-contact mapping system (Ensite 3000 system) providing a three-dimensional simultaneous display of arrhythmia activation may offer a solution. The non-contact mapping system consists of a specially designed balloon catheter (Ensite EP catheter) with 64 insulated wires over the surface of the balloon for sensing electrical potentials on the …
The Use Of Wallstent And Smart Stents Incarotid Stent-Supported Angioplasty, Steven Siu-Lung Li
The Use Of Wallstent And Smart Stents Incarotid Stent-Supported Angioplasty, Steven Siu-Lung Li
Journal of the Hong Kong College of Cardiology
In the endovascular approach of carotid stenosis treatment, stent-supported angioplasty is current state-of-the-art technique. Self-expandable stents are preferable to balloon-expandable stents due to the potential risk of deformation of the latter by external pressure. Wallstents and SMART stents are the more commonly used self-expandable stents. They appear to be of similar efficacy and safety but due to their different characteristics, their applications may be different according to different lesion characteristics.

The aims of this prospective, observational study were to compare: (1) symptom presentation of coronary heart disease (CHD) between patients with and without diabetes and (2) symptom predictors of CHD in patients with and without diabetes. We directly observed 528 patients with symptoms suggestive of CHD as they presented to the ED of a 900-bed cardiac referral center in the northeastern United States. There were no significant differences in symptom presentation of CHD between patients with and without diabetes, although patients with diabetes were slightly more likely to present with shortness of breath (P =.056). Patients with diabetes reported …

Results: During the span of eight years (1991-1998), 379 cases of salivary gland tumours were diagnosed. Of these, 205 (65.7%) were male and 174 (34.3%) were female. The median age at the time of diagnosis was 35 years. The median age for patients with malignant lesions (44 years) was 12 …
Effects Of Liposome-Encapsulated Tnf-Alpha And Radiation Against Colon Cancer, Dong Won Kim
Effects Of Liposome-Encapsulated Tnf-Alpha And Radiation Against Colon Cancer, Dong Won Kim
Loma Linda University Electronic Theses, Dissertations & Projects
Previous studies have shown that tumor necrosis factor-α (TNF-α) can augment the antitumor effects of radiation, inhibiting tumor progression to a greater extent than either modality alone. However, nonspecific toxicities associated with TNF-α have limited its use as an adjuvant. This limitation is potentially resolved with the encapsulation of TNF-α in sterically stabilized, PEGylated liposomes (STEALTH®). Thus, the overall hypothesis of the research was that the combination of radiation with STEALTH® liposome encapsulated TNF-α (SL-TNF-α) will have greater efficacy and fewer dose-limiting side effects in the LS174T human colorectal tumor xenograft model compared to the combination of free TNF-α and …
Arrhythmogenic Right Ventricular Cardiomyopathy, Wing-Hong Fung, Chi-Kin Chan, John E. Sanderson
Arrhythmogenic Right Ventricular Cardiomyopathy, Wing-Hong Fung, Chi-Kin Chan, John E. Sanderson
Journal of the Hong Kong College of Cardiology
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a familial form of cardiomyopathy predominantly affecting the right ventricle but may progress to involve the left ventricle as well. At the late stage of the disease, it is sometimes difficult to differentiate with other forms of dilated cardiomyopathy. In most affected families, the mode of inheritance of the disease is autosomal dominant. Lately, the gene accounting for the autosomal recessive form of ARVC, which was associated with palmoplantar keratosis, was identified. ARVC can present with sudden cardiac death without any preceding symptoms in the young population. Therefore, ARVC must be included in the …

BACKGROUND: The survival of recipients of cardiac allografts is limited by rejection, lymphoproliferative disease, and coronary vasculopathy. The purpose of this study in children who had received heart transplants was to evaluate the cardiac allografts for myocardial viral infections and to determine whether the presence of viral genome in the myocardium correlates with rejection, coronary vasculopathy, or graft loss.
METHODS: We enrolled heart-transplant recipients 1 day to 18 years old who were undergoing evaluation for possible rejection and coronary vasculopathy. Endomyocardial-biopsy specimens were evaluated for evidence of rejection with the use of standard criteria and were analyzed for the presence …

We assessed the influence of hormonal (oral, injectable, or levonorgestrel [Norplant, Wyeth-Ayerst, Philadelphia, PA]) and barrier methods of contraception on the risk of cervical squamous intraepithelial lesions (SIL), while adjusting for high-risk (HR) HPV infection. Subjects were women receiving family planning services through the state health department clinics from 1995 to 1998. We selected 60 cases with high-grade cervical/SIL (HSIL) and 316 with low-grade cervical/SIL (LSIL) and controls (427 women with normal cervical cytology) and analyzed cervical DNA for HR-HPV, using Hybrid Capture I (Digene; Gaithersburg, MD).When assessing ever use, duration, recency, latency, and age at first use, neither oral …
