AIMS To investigate the frequency of the single nucleotide polymorphism C3435T in exon 26 of the MDR1 gene in Asians and to determine the functional significance of this SNP with the clinical pharmacokinetics of oral cyclosporin (Neoral) in 10 stable heart transplant patients. METHODS The MDR1 C3435T polymorphism was investigated in 290 healthy Asian(More)
BACKGROUND Therapeutic drug monitoring of cyclosporine in heart transplant patients is used to monitor therapy and prevent rejection. Of the various methods available for performing therapeutic drug monitoring of cyclosporine, the method of limited sampling strategy for area under the concentration-time curve profiling has been used most widely recently.(More)
Because of its long half-life, there has been concern that chronic amiodarone therapy before heart transplantation may adversely affect early cardiac allograft function and delay patient recovery. We retrospectively analyzed the outcome of the last 50 patients undergoing heart transplantation at our institution (between September 1988 and September 1989).(More)
INTRODUCTION The status of heart transplantation in Singapore is reviewed in this article. MATERIALS AND METHODS The database of 40 consecutive heart transplantations from July 1990 through December 2007 is reviewed retrospectively. The data is compared with the 2008 registry data of the International Society for Heart and Lung Transplantation (ISHLT). (More)
We describe a 27y old female systemic lupus erythematosus (SLE) patient with salmonella bacteraemia who presented with fever, back pain and an enlarging heart size. A two dimensional echocardiogram (2D Echo) showed a mass in the right atrium. Subsequent computer tomographic (CT) and magnetic resonance imaging (MRI) studies showed that this had become a ring(More)
Diabetic foot infections, a common source of morbidity and mortality, often have been related to vasculopathy and neuropathy in its etiopathogenesis, especially in the elderly person with diabetes. However, blood flow in the neuropathic diabetic foot has not been evaluated extensively, and there is evidence of abnormal blood flow patterns in the neuropathic(More)
The introduction of cyclosporine as an immunosuppressant in early 1980s dramatically improved the outcome of organ transplantation. The adverse effects of nephrotoxicity and increased incidence of lymphomas were recognized with high doses of cyclosporine during the early part of that decade. This led to lower doses of cyclosporine and combination with(More)
We report a case of combined heart and liver transplantation for familial amyloid polyneuropathy. This is the first such combined transplant performed in Asia, and differs from previously described cases, in that cardiopulmonary bypass was continued at partial flow during liver transplantation in our case. This was done in order to provide haemodynamic(More)

The current techniques of donor procurement and transplantation provide a very low incidence "of non rejection graft failure", following cardiac transplantation. Attention needs to be paid to the preservation of organ function in the potential donor, in order to maximise the donor availability in an environment of perpetual donor shortage. The strategies(More)
