We report computed tomography (CT) findings for a rare case of follicular dendritic cell sarcoma of the greater omentum from a 47-year-old female patient. The tumor presented ash a palpable mass lesion in the umbilical region for the last two months. Multidetector CT scan of the abdomen showed a 14-cm soft-tissue mass with calcification and necrosis within the greater omentum. As a result, a follicular dendritic cell sarcoma should be considered in the differential diagnosis of a solitary omentum mass, especially one with coarse and chunk-like calcifications.

INTRODUCTION:
Identifying peripheral arterial disease (PAD) during diabetic foot screening (DFS) is crucial in reducing the risk of diabetic foot ulcerations and lower limb amputations. Screening assessments commonly used include absolute systolic toe pressure (ASTP) and toe-brachial index (TBI). There is a lack of research defining the threshold values of both assessment methods. We aimed to compare the accuracy of ASTP and TBI and establish optimal threshold values of ASTP and TBI with reference to the internationally accepted ankle-brachial pressure index (ABPI) screening test, for a multiethnic diabetic population in Singapore.
METHODS:
A retrospective, observational study of DFS results from January 2017 to December 2017 was conducted. Receiver operating characteristic analysis was conducted for ASTP and TBI using the internationally accepted ABPI cut-off value of ≤0.9 to indicate PAD.
RESULTS:
A total of 1,454 patients with mean (standard deviation) age of 63.1 (12.4) years old were included. There were 50.8% men and 49.2% women, comprising 69.7% Chinese, 13.5% Indian, 10.1% Malay and 6.7% other ethnicities. Areas under the curve for ASTP and TBI were 0.89 (95% confidence interval [Cl] 0.85-0.94) and 0.94 (95% Cl 0.90-0.98), respectively, and the difference was statistically significant (P<0.001). Derived optimal threshold values to indicate ABPI≤0.9 for ASTP and TBI were <95.5mmHg (specificity 0.86, sensitivity 0.84) and <0.7 (specificity 0.89, sensitivity 0.95), respectively.
CONCLUSION
ASTP or TBI may be used to detect ABPI-determined PAD in DFS. The optimal threshold values derived from a multiethnic Asian diabetic population were <95.5mmHg for ASTP and <0.7 for TBI.

Oxidative stress plays various roles in the development and progression of IgA nephropathy, while bilirubin is known as a potent antioxidant. We therefore hypothesized that serum bilirubin would be associated with renal prognosis in IgA nephropathy. The study subjects comprised 1,458 adult patients with primary IgA nephropathy in Korea. We grouped patients according to the following quartile levels of bilirubin: <0.4 mg/dL (Q1), 0.4-0.5 mg/dL (Q2), 0.6-0.7 mg/dL (Q3), and >0.8 mg/dL (Q4). The outcome data were obtained from the Korean Registry of end-stage renal disease (ESRD). Eighty patients (5.5%) contracted ESRD during a mean follow-up period of 44.9 months. The ESRD incidences were 10.7% in Q1, 8.2% in Q2, 2.8% in Q3, and 2.8% in Q4 (p<0.001). The relative risk of ESRD compared to that in Q1 was 0.307 (95% confidence interval [CI], 0.126-0.751) in Q3 and 0.315 (95% CI, 0.130-0.765) in Q4. The differences of ESRD incidence were greater in subgroups of males and of patients aged 35 yr or more, with serum albumin 4.0 g/dL or more, with normotension, with eGFR 60 mL/min/1.73 m2 or more, and with proteinuria less then 3+ by dipstick test. In conclusion, higher bilirubin level was negatively associated with ESRD incidence in IgA nephropathy.

Introduction: Literatures suggest that insufficient physical activity as one of the contributors to non-communicable chronic diseases; nevertheless, data on the physical activity level is sparsely reported among individuals practising a vegetarian diet in Malaysia. The current study aims to determine the prevalence of insufficient physical activity and its association with socio-demographic factors, lifestyle factors and body weight status among 273 individuals practising a vegetarian diet in Klang Valley, Malaysia. Methods: A set of self-administered questionnaire was distributed to all vegetarians and their data on physical activity was determined using the Global Physical Activity Questionnaire (GPAQ). Results: The average years of practising vegetarianism was 14.2±9.6 years, and most of the vegetarians were practised ovo-vegetarian diet (44.0%). A majority of them were Chinese (54.9%) and female (64.8%), with an average age of 47.5 ± 13.1 years. The prevalence of overweight and obesity were 27.5% and 8.1%, respectively. According to GPAQ, about two in five vegetarians (46.2%) were having insufficient physical activity. Being females, older age, Chinese, married individuals, and those with high total household income level were found to be significantly associated with low physical activity level among Malaysian vegetarians (p<0.05). Conclusion: Since insufficient physical activity is one of the factors contributing to non-communicable chronic diseases, it is crucial to educate the importance of physical activity on overall health status, specifically for those who at risk of physically inactive. In addition, future studies can focus the causal associations based on the currently identified factors and physical activity levels, which can help to develop an effective intervention program among Malaysia vegetarians.
