Patients’ satisfaction is of critical interest to all healthcare providers. Satisfied patients are more likely to seek health care and to comply with prescribed treatment regimes. The objective of the study was to identify factors that influence patient satisfaction with Emergency Department HUKM (ED HUKM). This study was conducted at ED HUKM from January 2007 till March 2007. A convenience sample of 100 participants was recruited from triage 4. The Davis Consumer Emergency Care Satisfaction Scale (CECSS) was adopted and modified. It consists of 19 questions; used a 5 point, Likert type scale of 1 to 5 (1= completely disagree and 5= completely agree) to measure patient satisfaction with triage, health care providers caring behaviours and health teaching. Results showed that 75 participants (75%) were satisfied. There were no significant difference found between male and female patients with total CESCC scores (t=0.308, p values >0.05). Pearson product moment correlation coefficients showed a positive relationship between total and subscale patient satisfaction scores, caring scores (r=0.905, p value <0.05) and teaching scores (r=0.695, p < 0.05). Overall, patients were satisfied with services at the ED HUKM. Patients’ satisfaction remains as an important quality outcome measure of emergency care in any hospital.

Interventional Pain Procedures (IPPs) is a relatively new treatment modality for chronic pain in Malaysia. The Interventional Pain Service (IPS) newly set up in our institution is led by a pain neurosurgeon and provides a whole package of multimodal pain management including different range of IPPs. This clinical audit is to examine the quality of IPPs performed within the IPS in our institution since its initiation. A total of 87 IPPs were performed on 56 chronic pain patients over 3-year duration. As high as 81.8% of the procedures were effective and 81.5% of patients were satisfied. Only one minor transient complication occurred after an intradiscal procedure but none resulted in death or permanent disability. Thus, safe and effective IPPs can be provided as part of IPS in a local neurosurgical pain centre to bring more comprehensive and less fragmented care for chronic pain patients.

BACKGROUNDCardiac resynchronization therapy (CRT) is an effective electrical therapy for patients with moderate to severe heart failure and cardiac dyssynchrony. This study aimed to investigate the degree of acute left ventricular (LV) resynchronization with biventricular pacing (BVP) at different LV sites and to examine the feasibility of performing transthoracic echocardiography (TTE) to quantify acute LV resynchronization during CRT procedure.

METHODSFourteen patients with NYHA Class III-IV heart failure, LV ejection fraction < or = 35%, QRS duration > or = 120 ms and septal-lateral delay (SLD) > or = 60 ms on tissue Doppler imaging (TDI), underwent CRT implant. TDI was obtained from three apical views during BVP at each accessible LV site and SLD during BVP was derived. Synchronicity gain index (Sg) by SLD was defined as (1 + (SLD at baseline--SLD at BVP)/SLD at baseline).

RESULTSSeventy-two sites were studied. Positive resynchronization (R+, Sg > 1) was found in 42 (58%) sites. R+ was more likely in posterior or lateral than anterior LV sites (66% vs. 36%, P < 0.001). Concordance of empirical LV lead implantation sites and sites with R+ was 50% (7/14).

CONCLUSIONSThe degree of acute LV resynchronization by BVP depends on LV lead location and empirical implantation of LV lead results in only 50% concordance with R+. Performing TTE during CRT implantation is feasible to identify LV sites with positive resynchronization.

OBJECTIVETo establish an assay for screening chromosome 22q11 microdeletion efficiently, and apply it for detecting del22q11 in patients with non-syndromic congenital heart defects (CHD).

METHODSSeventy nine patients with non-syndromic CHD and 84 normal controls were genotyped for 8 short tandem repeat (STR) markers located in 22q11 region, by using quantitative fluorescence polymerase chain reaction (QF-PCR).

RESULTSThe average heterozygosity of the STR markers in patients and controls was 0.76 and 0.79, respectively. One patient with Tetralogy of Fallot (TOF) from the 79 CHD cases (1.3%) was found to have a deletion within chromosome 22q11.2, which was confirmed by multiplex ligation-dependent probe amplification (MLPA).

CONCLUSIONThe QF-PCR assay developed in this study was a reliable and an efficient alterative approach to screen for 22q11 microdeletion in clinical diagnosis and genetic counseling.

BACKGROUNDPrevalence of atrial fibrillation (AF) is increasing as the world ages. AF is associated with higher risk of mortality and disease, including stroke, hypertension, heart failure, and dementia. Prevalence of AF differs with each population studied, and research on non-Western populations and the oldest old is scarce.

METHODSWe used data from the 2012 wave of the Chinese Longitudinal Healthy Longevity Survey, a community-based study in eight longevity areas in China, to estimate AF prevalence in an elderly Chinese population (n = 1418, mean age = 85.6 years) and to identify risk factors. We determined the presence of AF in our participants using single-lead electrocardiograms. The weighted prevalence of AF was estimated in subjects stratified according to age groups (65-74, 75-84, 85-94, 95 years and above) and gender. We used logistic regressions to determine the potential risk factors of AF.

RESULTSThe overall prevalence of AF was 3.5%; 2.4% of men and 4.5% of women had AF (P < 0.05). AF was associated with weight extremes of being underweight or overweight/obese. Finally, advanced age (85-94 years), history of stroke or heart disease, low high-density lipoprotein levels, low triglyceride levels, and lack of regular physical activity were associated with AF.

CONCLUSIONSIn urban elderly, AF prevalence increased with age (P < 0.05), and in rural elderly, women had higher AF prevalence (P < 0.05). Further exploration of population-specific risk factors is needed to address the AF epidemic.

BACKGROUNDThe association of long-term bisphosphonate treatment for osteoporosis and related safety problems such as atypical fractures were not clearly defined. This study was to evaluate the structural, densitometric and biomechanical properties of the prolonged bisphosphonate-loaded bones.

METHODSBone mineral density (BMD) at hip and femoral midshaft, bone cross-sectional area, moment of inertia of both femurs, bone formation and resorption biochemical markers were compared between 28 elderly with at least 4 years of bisphosphonate treatment from 2002 through 2006 and age-matched group of 37 elderly.

RESULTSThe total hip BMD and t-score were found not different between two groups. However, bisphosphonate treated patients were found to have significantly lower bone mineral content in the femoral shaft (P < 0.05); morphological study showed lower cross-sectional area in subtrochanteric and mid-diaphyseal region and thus significantly lower moment of inertia (P < 0.01). High resolution-peripheral quantitative computed tomography showed significantly decreased trabecular density, bone volume ratio, trabecular number but increased trabecular spacing in tibia and distal radius. Finite element analysis further confirmed significantly lower stiffness and failure load in tibia. Biochemical studies also showed lower bone resorption and severely suppressed bone formation activity (P < 0.001).

CONCLUSIONSThe unchanged total hip BMD between two groups confirmed the beneficial effects of bisphosphonate on trabecular bone, thus preventing osteoporotic fractures at large in previous studies. However, the inferior structural, densitometric and biomechanical properties at cortical bones, especially femur midshaft, need a special attention to look into the association between long-term bisphosphonate intake and the occurrence of stress fractures. When patients taking bisphosphonate complain of proximal thigh pain or discomfort, plain X-ray film can be the first line screening. All patients prescribed with bisphosphonate should be informed of such a complication though we must stress its rarity.
