The aim of this work is to report our three-years experience in the endovascular laser treatment of lower limbs varicose veins. After the evaluation of results after a middle-term follow-up, Authors discuss about an enlargement of indications to this method, and suggest some original technical details.
The Authors report the outcomes of an epidemiology study concerning the external genital pathologies, carried out on 2400 young males, ranging between 18 and 22 years who underwent the medical inspection for admission to the Air Force Academy. Basing on an andrologic clinical and anamnestic protocol, 229 cases with genital abnormalities, and among them 171 cases of varicocele (8.16%), were detected. The presence of varicocele in all the selected cases was confirmed with proper instrumental investigations (CW Doppler, ecocolorDoppler, telethermography). A randomized sample of 240 out of the 2400 young males, underwent the same investigations as a routine. These investigations enhanced the accuracy in detecting the varicocele, and allowed to identify 3 new cases, all classified as 1st type, in addition to the 19 previously correctly detected by the clinical and anamnestic examination.
The Authors report in this paper the outcomes of a post-operative study based on echo and echo-color imaging in 10 patients who underwent surgery for bilateral groin hernia. On both sides the operation was performed with a "patch and plug" implantation, according to the Rutkow technique. On right sides the polypropilene mesh was fixed to the inguinal orifice with cardinal stitches, while on left sides the mesh was shaped and spreaded on the orifice without any fixation. The U.S. postoperative pictures, performed up to 30 th p.o. day, showed a better stretching of the unfixed meshs, probably owed to a better adapting capability of the free mesh inside the tissues in standing position. The Authors consider significative the correlation between images showing in 7 patient's right sides little irregularities in mesh display, with presence of thin liquid filled spaces, and the moderate postoperative pain, that occurred in the same side in 6 of them.
The aim of this work was to clearly illustrate that the haemodynamic pathogenesis of the varicocele can be a consequence of a retrograde flux along the internal spermatic vein. The reflux is due to the use of a different path of drainage along the internal spermatic vein, which uses some collateral routes of the vessel, and mainly the nephrogenital branch. The diminishing pressure in the final segment of the internal spermatic vein is the focal points of the pathogenesis of the disease. The ontogenetic processes that lead to the formation of the left renal vein help in explaining the almost general one-sidedness of the disorder, its frequency and the fact that it is mostly the young who are affected by it. In fact, the variability of the timing and of the extension of the involution of the primitive venous system and of the processes of evolution which lead to the morphological definition of the tracts of the genital flow down, lead to the various manifestations of the idiopathic varicocele. This theory which also takes into account the physiological mechanisms of the venous drainage to the testicle in an anti-gravitation sense is part of the patterns that, under the diaphragm, rule the entire venous return of the blood toward to the heart.

The relation between suture material and consolidation and healing in operations on the colon was investigated by using silk and catgut in one group of disinfected stray dogs subjected to right or left hemicolectomy and resection of the transverse portion, and a synthetic reabsorbable material (polyglycolic acid) in another. The following parameters were assessed following removal of the segment containing the anastomosis after various periods of time: resistance to biomechanical tests, stenosis of the lumen, extent and duration of inflammation and regeneration at the edge. Reabsorbable material was associated with less overall inflammation and healing was more rapid. Consolidation of the suture was not significantly different in the two groups.
