Role of duplex doppler in evaluation of portal hypertension as a comparative study between bilharzial and non-bilharzial causes

Duplex Doppler has become powerful diagnostic tool in illustrating the morphology and haemodynamics of portal hypertension. We found that the maximum and mean blood flow velocity of the portal vein were less than control group with no significant difference between bilharzial and non bilharzial groups, while blood flow velocity in splenic vein was slower in 13 cases 3 cases. Blood flow volume did not show significant changes. Congestion index was elevated in portal hypertension with no significant difference between bilharzial and non billiarzial groups

Ultrasonography of hip lesions in children

Sixty-five children with painful hip joint or a limp were examined by sonography and plain radiography. The clinical, radiological and sonographic findings were correlated with the final diagnosis. Transient synovitis was diagnosed in 40 children. Sonography had shown effusion in only 30 patients and plain films showed effusion in only 3 cases. Acute septic arthritis of hip joint was diagnosed in 3 cases and haemo-arthrosis in 3 cases where sonograms showed fluid collection and needle aspiration was done to confirm the diagnosis. Sonography showed earlier changes before plain films become positive in cases of early Perthes' disease and in congenital dislocation of the hip in neonates. Our conclusion is that ultrasonography is a useful, non-invasive and more sensitive than plain X-ray for detection hip joint effusion, early Perthes' disease and congenital dislocation of the hip in neonates
