Eccentric and concentric torque and power of the knee extensors of females.

The purpose of this study was to compare differences in eccentric and concentric peak torque and power measurements of knee extensors at different velocities. The subjects included 21 females between the ages of 19 and 28, who had no history of knee pain or abnormality. Eccentric and concentric contractions of the knee extensors of the dominant leg of each subject were tested on an isokinetic dynameter at 60 degrees/s, 120 degrees/s and 180 degrees/s. Eccentric peak torque was greater than concentric at each of the three velocities tested, whereas eccentric power was significantly greater only at the two higher velocities. The lack of change in concentric peak torque between 120 degrees/s and 180 degrees/s contrasted with results of other studies, probably owing to methodological differences. Eccentric torque increased from 60 degrees/s to 120 degrees/s, but decreased again at the highest velocity. Both concentric and eccentric power increased with velocity.

[Palliative treatment of liver neoplasms I: localized infusion of antimitotics: premises, technical procedure and limitations]. / Trattamento palliativo delle neoplasie epatiche nota I: L'infusione distrettuale di antimitotici: premesse, modalita' tecniche e limiti.

A hepatic localised antiblastic chemotherapic technique combining limited discomfort for patients with appreciable palliative results is illustrated; a short description of the surgical procedure of intubation of the hepatic artery itself and of some auxiliary procedures is given. Lastly the possible complications and the results are illustrated.

[Palliative treatment of liver neoplasms II: dearterialization of the liver: indications, premises, technic and limitations]. / Trattamento palliativo delle neoplasia epatiche nota IIa: la dearterializzazione del fegato: indicazioni, premesse, technica e limiti.

Hepatic arterial vascularisation, as described by Michels in 1954, is outlined; the importance of selective angiography in preparation of the hepatic de-arterialisation operation is then stressed, and its theoretical foundations and the surgical technique are illustrated; other procedures which can usefully be combined are also indicated. Lastly an evaluation of the limits and results of this therapy is given.

[Digestive hemorrhage as a complication of a pancreatic pseudocyst]. / L'emorragia digestiva quale complicanza di una pseudo-cisti pancreatica.

A study was made at the Padua University Second Surgical Clinic--located in Verona--on four cases of digestive haemorrhage in patients with pancreatic pseudo-cysts. The psysiopatological, diagnostic and therapeutic problems inherent in this pathology are discussed. In particular, attention is drawn to the need for and difficulty of marking a correct diagnosis in good time, and the utility, for such purpose, of endoscopic examinations and selective arteriography of the coeliac tripod and the superior mesenteric artery. Lastly, the various possibilities that surgery offers in the treatment of this disease are mentioned.

[The Budd-Chiari syndrome: clinical case reports]. / La sindrome di Budd-Chiari: contributo clinico.

Two cases of Budd-Chiari's Syndrome are presented. These refer to two women aged 34 and 33 years respectively. The aetiology of the first case is linked to polycythaemia rubra and the use of oral contraceptives; that of the second case to a fibrous perihepatitis involving the outlet of the suprahepatic veins, with a tenacious action of stenosis. The surgical therapy used was a latero-terminal left porto-renal shunt in the first case, and a decapsulation and ligature of the common hepatic artery in the second case. In the discussion the aetiopathogenetic, diagnostic and therapeutic problems inherent in the Syndrome are analysed, also on the basis of the most recent experiences reported in the relevant literature.
