RESUMO
INTRODUCTION: Pancreatic duct stones are found in 22 to 60% of patients with chronic pancreatitis (CP). The stones can lead to obstruction of the outflow of pancreatic secretions causing increased intraductal pressure. The pancreas is relatively noncompliant. Therefore the rise in intraductal pressure can induce tissue hypertension and ischemia. This can be a major factor causing pain in patients with CP. This hypothesis is supported by the observation that symptoms may improve following pancreatic duct drainage. CASE PRESENTATION: A 62-year-old woman presented with persistent epigastric pain. Investigations revealed calcifications within the main pancreatic duct and head of the gland. Treatment with endoscopic retrograde cholangiopancreatography (ERCP) and extracorporeal shock wave lithotripsy (ESWL) achieved a good outcome. CONCLUSION: Standard endoscopic removal of the stones proved impossible so treatment with ESWL was undertaken. Following fragmentation, the calculi and fragments passed spontaneously or were removed endoscopically. If pancreatic stones cannot be removed endoscopically, ESWL should be considered prior to surgery.

We report the case of a man with chronic tophaceous gout who had end-stage renal failure secondary to the Alport syndrome. Following a failed kidney transplant, where urate deposition was a suspected contributor, the patient responded positively to consistent allopurinol therapy and regular haemodialysis sessions. Extensive and destructive tophi receded in size remarkably and the almost constant incidence of acute attacks of gout subsided. The patient has recently received a new kidney transplant and his plasma concentrations of urate are controlled well with allopurinol and he no longer experiences acute attacks of gout. While efficacious, adherence is critical for achieving the therapeutic effects of allopurinol even in end-stage renal disease.
