Eight cases of Boerhaave's syndrome detected in our hospital between 1980-1989, are reported. The clinical presentation, with chest pain, subcutaneous or mediastinal emphysema and hydropneumothorax should suggest oesophageal perforation. Contrast swallow examination with barium was diagnostic. Prognosis depends essentially of an early diagnosis and a rapid therapeutic decision.
Megacalyces is an uncommon congenital urinary anomaly consisting of oversized calyces and a renal pelvis of normal caliber. The under development of the pyramids with lack of projection of the papillae into the calyces probably produces the dilatation of the calyces. The diagnostic criteria are the characteristic appearance of the calyces, the normal caliber of the pelvis and ureter, and the absence of vesico-ureteral reflux. Two cases of congenital megacalyces are presented.
