A series of 135 knee arthroscopies has been reviewed to determine the accuracy of detection of meniscal lesions. Arthroscopy and double-contrast arthrography achieved similar accuracy (84 per cent and 86 per cent) in the diagnostically more difficult knees of the series. The combined accuracy of both examinations was 98 per cent. Arthroscopic difficulty in seeing the posterior third of the medi...

The effect of some endogenous components -endogenous opiates, cholecystokinin (CCK), vasoactive intestinal polypeptide (VIP) and somatostatin-as inhibitory or excitatory transmitters in the local nervous pathways involved in peristaltic responses was examined. The peristaltic reflex was studied using a modification of the Trendelenberg preparation. In each preparation, the luminal distens...

megacystis microcolon intestinal hypoperistalsis syndrome (mmihs) is a rare and the most severe form of functional intestinal obstruction in the newborn. the characteristic features of this congenital and fatal disease are abdominal distension, absent or decreased bowel peristalsis. abdominal distension is a consequence of the distended, unobstructed urinary bladder with or without hydronephros...
