Background: Peritoneal dialysis (PD) affords patients increased independence and improved quality of life. However, the lack of more frequent monitoring may compromise outcomes and decrease wider uptake of this modality. This study uses a novel tablet computer-based interface to allow real-time monitoring and two-way communication to better link PD patients with a dialysis center and care providers. Methods: A tablet computer with an application that allows enhanced monitoring of all aspects of PD was given to patients to assess their usage in a pilot trial. The interface allows patients to review sterility techniques, enter vital signs and exchange data, upload media such as photos and video clips, synchronize data to be viewed by medical staff, and allow real-time adjustments to the PD prescription. Satisfaction with the interface and comments for enhancement were analyzed using a simple self-administered questionnaire. Results: Six continuous ambulatory PD patients were enrolled in this pilot study. A total number of 1,172 exchanges were recorded over a period of 251 days. Compliance with the applications ranged from 51 to 92%. No major adverse events were recorded. The overall impression of the interface was 5.2 out of 10. The major criticism was that the application needs to be adjusted depending upon the experience level of the patient and that data entry needs to be simplified and automated. Conclusion: A tablet computer platform is a feasible concept for continuous ambulatory PD. The major components include flexibility, advanced infrastructure, two-way communication, and real-time interaction. This may encourage more patients to take up PD as their preferred modality of therapy for end-stage renal disease. Modifications to enhance use will be incorporated in subsequent versions.

Background: Simple renal cysts are usually asymptomatic and benign. Rarely, symptoms and complications can develop from local mass effect which is illustrated by this case. Case Presentation: 77 year old Caucasian male presents with abdominal pain for five days. Abdominal exam was diffusely tender, markedly distended, tympanic with absent bowel sounds. His work-up included an abdominal x-ray showing a colonic obstruction and abdominal CT showing a large 27 cm renal cyst. Drainage of the renal cyst resolved obstructive symptoms. Conclusion: A simple renal cyst should not be overlooked as the reason for acute abdominal pain. Simple renal cysts, though benign are not without complications. © Harrington et al.; Licensee Bentham Open.

Background: Alveolar hemorrhage can be seen in many vasculitic disorders. However, granulomatosis polyangiitis (formerly Wegener's granulomatosis) uncommonly presents with life threatening alveolar hemorrhage and has only been discussed in a few case reports [1]. Case Presentation: A 53 year old Caucasian male presented with hemoptysis and profound anemia. Two weeks prior, he had presented with abdominal pain with normal renal function and numerous pulmonary nodules. During the current admission, the patient was hypoxic with acute renal failure requiring hemodialysis. Urine sediment demonstrated dysmorphic red blood cells. A bronchoscopy revealed diffuse alveolar hemorrhage. The diagnosis of pulmonary-renal syndrome was made and therapeutic plasma exchange was initiated. Laboratory studies were significant for a c-ANCA titer positive at 1:640 FIU and anti-proteinase (PR)-3 antibody titer positive with 78.3 U/ml. Renal biopsy demonstrated necrotizing crescentic glomerulonephritis. A diagnosis of granulomatosis vasculitis was determined. Conclusion: Alveolar hemorrhage is rare to be the presenting symptom of granulomatosis vasculitis where the common presenting features are recurrent sinusitis, epistaxis, chronic otitis media or rhinitis. Physicians should consider granulomatosis vasculitis in the differential diagnosis of pulmonary-renal syndrome presenting with hemoptysis.
