INTRODUCTIONThe incidence of lymphoceles - lymphatic collections around a transplanted kidney - can be as high as 20%. We aimed to review the presentation, treatment and outcome of patients with lymphoceles.

METHODSWe reviewed a prospective database of 154 patients who underwent renal transplantation at our hospital from January 2005 to November 2008.

RESULTSThe mean age of the patients in our cohort was 46 (range 34-58) years. The incidence of lymphoceles in our series was 5.8% (n = 9). The median onset was 19 (range 6-28) days post-transplantation, while the median size of the lymphoceles was 5 (range 1.5-8) cm. Lymphoceles were most commonly found at the lower pole of the transplanted kidney. Eight patients with lymphoceles had received cadaveric transplants. While a majority of these patients did not have hydronephrosis on presentation, four had markedly elevated creatinine. Of the nine patients with lymphoceles, six were on macrolides (tacrolimus, sirolimus or everolimus), two were successfully managed conservatively, three were managed percutaneously and four required surgical drainage via either laparoscopic marsupialisation (n = 1) or open drainage (n = 3). There was no graft loss.

CONCLUSIONIt remains unknown whether the choice of immunosuppressants increases the risk of lymphocele formation. Intervention is necessary in the case of impaired drainage of the pelvicalyceal system in these patients. Minimally invasive intervention, while effective in treating lymphoceles, does not provide definitive treatment. Surgical intervention should be considered early for the treatment of post-transplantation patients with lymphoceles, so as to shorten hospital stay and prevent further complications.

We report the rare case of a patient with advanced renal cell carcinoma (RCC) who initially presented to the hospital with symptoms of cardiac failure. Preoperative cardiac studies did not reveal any underlying ischemia. After resection of a large 14-cm left renal tumor, cardiac function was noted to improve dramatically. We discuss this case of concomitant RCC and nonischemic cardiomyopathy.

PURPOSE: Smoking has detrimental effects on asthma symptom control and response to treatment and is prevalent among asthma patients in South Korea. The aim of this study is to determine the prevalence of smoking among asthma patients in South Korea and to compare the medication regimens of asthma patients who do and do not smoke. METHODS: A cross-sectional survey was conducted from August 2010 to January 2011. Participating physicians (N=25) recorded demographic and clinical data on all asthma patients presenting during the study period (N=2,032), and then recruited a subset of patients (N=500) for the survey such that half were self-reported current smokers. Recruited patients were between the ages of 18 and 60. RESULTS: Among presenting asthma patients, 17.3% were current smokers, 19.2% were former smokers, and 63.5% had never smoked. Within the analyzable study population (N=471), 212 patients reported smoking currently, 79 smoking formerly, and 180 never smoking. Among current and former smokers, 79.7% and 81.0%, respectively, were men, while women represented 80.5% of patients who had never smoked. Agreement was strong between physician-determined smoking status and patient-reported smoking status (kappa=0.82; P<0.001). However, asthma medication regimens examined according to GINA treatment steps did not differ by smoking status. In addition, mean quality of life scores and level of asthma control did not differ by smoking status. CONCLUSIONS: In South Korea, physicians are well aware of the smoking status of their patients. However, smoking status did not affect the prescribed medication regimens of this population of asthma patients.

INTRODUCTION: Numerous heart failure risk scores have been developed but there is none for Asians. We aimed to develop a risk calculator, the Singapore Heart Failure Risk Score, to predict 1- and 2-year survival in Southeast Asian patients hospitalised for heart failure. MATERIALS AND METHODS: Consecutive patients admitted for heart failure were identified from the Singapore Cardiac Databank Heart Failure registry. The follow-up was 2 to 4 years and mortality was obtained from national registries. RESULTS: The derivation (2008-2009) and 2 validation cohorts (2008-2009, 2013) included 1392, 729 and 804 patients, respectively. Ten variables were ultimately included in the risk model: age, prior myocardial infarction, prior stroke, atrial fibrillation, peripheral vascular disease, systolic blood pressure, QRS duration, ejection fraction and creatinine and sodium levels. In the derivation cohort, predicted 1- and 2-year survival was 79.1% and 68.1% compared to actual 1- and 2-year survival of 78.2% and 67.9%. There was good agreement between the predicted and observed mortality rates (Hosmer-Lemeshow statistic = 14.36, = 0.073). C-statistics for 2-year mortality in the derivation and validation cohorts were 0.73 (95% CI, 0.70-0.75) and 0.68 (95% CI, 0.64-0.72), respectively. CONCLUSION We provided a risk score based on readily available clinical characteristics to predict 1- and 2-year survival in Southeast Asian patients hospitalised for heart failure via a simple online risk calculator, the Singapore Heart Failure Risk Score.
