ABSTRACT
<p><b>INTRODUCTION</b>The 'DOT & Shop' scheme is sponsored by SATA CommHealth, a local non-governmental organisation. It was launched in July 2009, in collaboration with Singapore's Tuberculosis Control Unit (TBCU). Under this scheme, grocery vouchers are disbursed to low-income patients with tuberculosis (TB) at each clinic visit if they have been adherent to directly observed therapy (DOT). This study aimed to determine the effect of this incentive scheme on treatment completion rates and to report the characteristics of patients who were non-adherent to the scheme.</p><p><b>METHODS</b>This descriptive study used data from the TBCU medical social worker database and the National TB Registry.</p><p><b>RESULTS</b>From July 2009 to December 2012, a total of 883 TB patients were enrolled in the scheme. The overall treatment completion rates of the patients before (July 2006-June 2009) and after (July 2009-December 2012) the implementation of the scheme improved from 85.3% to 87.2% (p = 0.02). Patients under this scheme had a higher treatment completion rate (90.0%) than those not under this scheme (86.4%) (p < 0.01). It was found that the non-adherent patients were more likely to be of Malay ethnicity, younger and unemployed.</p><p><b>CONCLUSION</b>We demonstrate the salutary effect of a non-governmental organisation-funded grocery voucher incentive scheme for low-income TB patients on DOT in Singapore.</p>

Colorectal carcinoma is a common lethal disease with signs and symptoms that may be nonspecific. Computed tomography (CT) of the abdomen and pelvis with or without contrast is frequently performed for various general abdominal complaints, but unlike CT colonography, the large bowel may not be optimally prepared for evaluation. As such, careful and diligent assessment of the non-prepared colon in all CT images of the abdomen and pelvis is important, as it ensures that incidental colorectal malignancy is not missed, especially in older patients. This article gives an overview of multidetector CT imaging signs and subtle clues to aid in the diagnosis of colorectal carcinoma, as well as their pitfalls.
