[Neurolysis of the posterior tibial nerve in the tarsal canal--a new therapeutic approach in chronic painless plantar ulcers].

The paper reports on 14 cases of perforating plantar disease of whom 11 belong to the so-called nonpainful chronic plantar ulceration by compression of the posterior tibial nerve in the tarsal canal. The authors show clinically, neuroelectrically and by neurography with lipiodol that in the case of a diabetic or alcoholic polyneuropathy, the posterior tibial nerve is more vulnerable to the compression existing in the tarsal canal due to the development of a fibrous sclerotic tissue. Exo-endoneurolysis of the posterior tibial nerve associated with a posterior tibial periarterial sympathectomy permitted healing in 7 ulcerations, 2 diminutions of the ulceration dimensions, and only 2 remissions.

[Tumors of the soft parts of the extremities. Anatomoclinical and therapeutic aspects].

A total of 60 cases are presented, of patients with tumours of the soft parts of the limbs, from a total of 14,000 surgical interventions. Of the total 18 were malignant tumours, while the remaining 42 cases had benign tumours. Tumours of the soft parts of the limbs include a large variety of histologic forms, and this raises particular problems of diagnosis and treatment.

[Hyperlipoproteinemia, a factor of severity in acute pancreatitis].

The authors make a retrospective analysis of 95 cases of acute pancreatitis hospitalized between 1975 and 1979. In 3,8% of all the cases the acute pancreatitis was associated with hyperlipoproteinemia. The study of the 4 patients involved revealed the primary origin of hyperlipoproteinemia as a result of alimentary abuse in 3 of the cases.

[Phyllode tumors: anatomoclinical and therapeutic aspects (5 clinical cases)].

The phyllodes tumour is a bi-tissular mammary tumour. It is essentially benign but potentially sarcomatous, presenting multiple clinical and histologic-aspects, and raises difficult problems of diagnosis and therapeutic attitude. Four histological types are described, from the adenofibromatous type to the sarcomatous one.
