The endoscopic technique in chronic venous insufficiency is simple and almost complication free. Our preliminary results due to a good postoperative course and to a quick return to social activity induce the Authors to indicate this type of procedure as the best treatment in chronic venous insufficiency.
The employment of prosthesis in abdominal plastic surgery for incisional hernia has contributed to a remarkable improvement in the results of this surgery. The current use of PTFEe, according to the Authors experience, proves to be effective. Both satisfactory functional results and evident aesthetic advantages are obtained. The Authors report their experience in the treatment of the median incisional hernia also by means of a polypropylene mesh. The latter was shaped in a very original way thanks to a technique borrowed from plastic surgery. The complete mobilization of the ombilicus, by a circular incision, allowed the Authors to insert this prosthesis symmetrically under the rectus abdominis muscles for the entire extension of the incisional hernia.
The experience in a case of primitive stromal sarcoma of the breast brought the Authors to study and to characterize the surgical interventions to prefer in these tumors. Criteria of radicality are considered in the light of the modern notion of "anatomical compartment" already applied to the sarcomas of the musculoskeletal or parenchymal location, from which breast sarcomas don't differ in order to the clinical behavior.
The Authors report their experience in the management of 30 patients undergone tension free hernioplasty according to Trabucco for inguinal hernia. Results and some modifications of the original technique are discussed.
From a retrospective analysis of 181 cases observed in a ten-year period (1980-1990), the authors registered a frequency of bilateral breast cancer comparable to that reported in the literature (1-12%). Early diagnosis is the only factor able to modify positively the prognosis, through an accurate follow up, based on blood and X-ray tests (low-density mammography).
A case of lithiasis due to indwelling double J ureteral stent is described. Pathogenesis and possibilities of prevention are discussed.
Three cases of galactocele appeared as breast nodule during lactation are reported. From our experience and the recent literature, ultrasound shows a good reliability for the diagnosis of breast diseases during pregnancy and lactation in spite of oedema and breast turgidity, distinctive of these periods.
The authors report their experience with 453 cases of thyroid nodules observed over a period of 5 years. The intention was to determine the incidence of malignant lesions. A female prevalence of the nodular pathology was clearly evident (7.2%), with a maximum incidence between the 3rd and 6th decade. Among malignant tumors (14.2%) the following histologic types were most frequently found: papillary adenocarcinoma (5.7%), follicular adenocarcinoma (2.7%), occult cancer (2.7%), anaplastic cancer (2.3%). Up to the 4th decade female prevalence was clearly evident (Max in the 3rd decade; F/M ratio = 6.5); then an increased male incidence was registered bringing to a reduction of the F/M ratio (1.5 in the 5th and 6th decade) and to its inversion in the 7th decade (M/F = 1.25).
The authors suggest to treat the stenosis of the posterior urethra with a technique able to prevent relapses as much as possible. For this reason they recommend the improved technique of Sachse as the more suitable, avoiding, though, irritative stimuli (resections and indwelling catheters).
A case of benign prostatic hyperplasia with lateral lobes large involvement is reported. On the basis of their own experience and a review of the literature the role of hormonal synergism in the development of the condition is outlined.
The Authors report a rare case of mediastinal chondrosarcoma. Diagnosis, cytology and therapeutic problems are underlined.
The Authors evaluate cystourethrography with and without chain as a method to study urethral diseases. Indications and complications are considered positively, because they allow an easy and safe control of the cases operated.

Pools of ticks, Ixodes (Ceratixodes) uriae collected between 1975 and 1979 at Macquarie Island, yielded 33 strains of at least 4 different viruses: Nugget virus (Kemerovo group), 1 strain; Taggert virus (Sakhalin group) 9 strains; a previously undescribed flavivirus, related to Central European Tickborne encephalitis virus, for which the name "Gadgets Gully" is proposed, 9 strains; a virus serologically related to the Uukuniemi serogroup, family Bunyaviridae, for which the name "Precarious Point" is proposed, 10 strains. Three isolates were mixtures of Nugget and Gadgets Gully viruses; the remaining virus strain remains unidentified.
