In this paper, we describe several IVR usage and learnability insights that emerged from a singing competition held by a community radio station located in an urban community of low-income migrant workers. Our community radio station partner, Gurgaon Ki Awaaz, relies heavily on folk songs to build its content repository and develop a close rapport with its(More)
PURPOSE To determine the outcomes and to identify prognostic variables determining mortality and recurrence after surgery for renal cell cancer (RCC) with venous involvement. METHODS Retrospective evaluation of the medical records of 132 patients with RCC and tumor thrombi treated at Johns Hopkins Hospital (1997-2008) was done. Kaplan-Meier analysis was(More)
BACKGROUND AND PURPOSE Urinary Citrate is an inhibitor of Calcium oxalate stone formation. It is reabsorbed in the proximal kidney through sodium dicarboxylate co-transporters (NaDC-1, NaDC-3) present in the renal tubular epithelium. Lithium (Li) is a known potent inhibitor of these transporters. We investigated the effect of lithium carbonate (LiC) and(More)
BACKGROUND AND PURPOSE Postoperative hemorrhage is a significant risk after laparoscopic partial nephrectomy (LPN). Hemostatic agents have become increasingly popular as adjuncts to renorrhaphy because of their potential to minimize intracorporeal suturing and lessen warm ischemia time. The objective of our study was to compare the safety and efficacy of an(More)
Malignant mesothelioma (MM) of the tunica vaginalis is a rare aggressive tumor with a high predilection for metastatic spread. Because there is no preoperative diagnostic modality available, it has high recurrence and mortality rates, which emphasizes the importance of early preoperative diagnosis for proper and adequate treatment. We describe a case of MM(More)
PURPOSE We describe perioperative complications associated with renal cryoablation and identify potential risk factors for certain complications. MATERIALS AND METHODS We retrospectively analyzed the medical records of patients with unifocal renal masses treated with cryosurgery at a single center between 1997 and 2007. All complications associated with(More)
e15034 Background: Data is scarce on prognostic variables determining recurrence and mortality after surgical resection in patients with renal cell cancer (RCC) and tumor thrombus. METHODS Retrospective evaluation of the medical records of 132 patients with RCC and tumor thrombi treated at Johns Hopkins Hospital (1997-2008) was done. Demographics, tumor(More)
Gastric tumors confined to mucosa and submucosa can be resected with endoscopic resection techniques. They include endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) [1, 2]. These techniques can be challenging when the tumor is large or is near the gastroesophageal (GE) junction. Transgastric resection is a novel technique of(More)
Interactive Voice Response Systems (IVRS) have been used extensively to engage with poorly literate populations in the context of public health, farming, community radio, citizen journalism, and other sectors [2--7]. The voice based medium on IVRS, and the easy to use phone interface, seem to have been useful to help poorly literate and non-IT savvy(More)
