Integration of ultrasound in medical School: Effects on Physical Examination Skills of Undergraduates.

Introduction: Ultrasound (US) imaging has rapidly increased its application in almost every medical field. Many universities worldwide provide teaching of US for undergraduates in their curricula. Emerging evidence is supporting the use of ultrasonography to improve also non-US skills and knowledge of medical students.

[Action of dihydroergotamine in venous insufficiency of the lower extremities. A clinico-instrumental study].

The therapeutical activity of DHE in venous insufficiency of the lower extremities was studied. Changes in the peripheral venous pressure curve, coupled with the clinical and rheographical parameters, pointed to the drug's real effectiveness in the treatment of functional insufficiency.

[Surgical treatment of recurrent varices].

The AA describe the different kinds of operation, on the base of the different kinds of relapsing varices. They outline the importance of a through isolation of internal saphena vein at sapheno-femoral "cross" and of external saphena at sapheno popliteal "cross" for avoiding "high" relapses. They they insist on the subfascial ligature of incontinent perforating veins and on the closing of open muscular breach though a "zed" stitch.

[Etiopathogenesis and classification or recurrent varices].

The AA examine the most frequent causes of relapsing varices: they remember that the exact anatomic knowledge of sapheno-femoral and and sapheno-popliteal crosses in essential for the execution of an exact operation; rapidly they inspect the casuistry of S. Giuseppe Hospital, classifying the relapses on the base of a topographic standard and seeing that the technical mistake is essential for the relapses.
