[Nodular thyroid disease: comparison of diagnostic techniques. Our experience].

The Autbors, on the basis cf tbeir series 0/553 pntients affected b)' goiter, report an analysis on the results o/ tbe different diagnostic techniques used in order to establisb the most adequate in identifling the type oflesion, with particular attention to neoplastic degeneration

[A case of renal infarction: clinical and anatomic contribution].

A case o/ renal infarction presenting with acute abdomen is reported. Due to the extended renal damage nephrectomy wasperformed. Macroscopic appearance o/ the kidney (prevalent cortical vascular inforction) and o/ the surrounding tissues (retroperitoneal edema and abdominal ascites) suggested a comparison with epidemie haemorrhagic flver. Vascular supp/y to the kidney, in such cases, depends on the perforating arteries which may increase in number and size

[Ambulatory phlebectomy: our experience].

The Authors report their experience of out-patient phlebectomy. Over a period of 5 years they have examined 186 patients (156 females, 30 males): 166 had micro- and extra-saphenic varicosities, while 20 had recurrent varices. Patients with ostium failure were excluded. Muller's out-patient phlebectomy implies an accurate mapping of varicosities, local anaesthesia, microincisions which are only exceptionally sutured. The Authors consider that an accurate elastic pressure bandage is indispensable and useful in order to improve the dynamics of the PVC and to avoid haemorrhages. Such a surgical technique bears aesthetic, economic and haemodynamic advantages

[Nephrogenic metaplasia. A particular clinical and anatomopathologic entity].

Two cases of nephrogenic adenoma are presented. The authors consider nephrogenic metaplasia as a reaction to inflammatory agents and point out the importance of differential diagnosis with nephrogenic adenocarcinoma, in which a different surgical procedure is requested

Pseudosarcoma of the urinary bladder. Report of a case.

A case of myofibroblastic pseudosarcomatous tumor of the bladder occurred in a patient previously submitted to TURB is reported. Aim of this investigation is to demonstrate, on the basis of the literature, the importance of histopathology in the diagnosis of bladder pseudosarcoma, since endoscopical and radiological methods can erroneously show a neoplasm. A 65-year-old male patient with hematuria, submitted to ultrasonography and cystoscopy, revealed a bladder superficial papillary formation. A TURB was performed and the histological study showed a superficial bladder cancer (T1-G1-2). After a second hematuria episode with stranguria a new bladder formation was diagnosed and resected; the histological study revealed a bladder pseudosarcoma. The absolute benignity of the lesion and the slight difference in the symptomatology between urothelial carcinoma and pseudosarcoma are underlined. Furthermore, the importance of histopathology to obtain an accurate diagnosis is stressed. The difficulty of a preoperative diagnosis without histopathological examination is pointed out

[Tietze's syndrome: importance of differential diagnosis and role of CT].

A case o/ Tietze's syndrome is reported. A 55-year-old woman had experienced left anterior cbest pain and tender swelling o/ the left second costosternal junction flr one month. CT Showed:j;0cal enlargement o/ tbe left second costai cartilage with partial calci cation. Six rnonths ater a complete recovery was registered and a second CT scan uras negative. These clinica! and CT findings are consistent with Tietze's syndrome

[Endoscopic surgery of chronic venous insufficiency (CVI)].

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

[Blind-ending branch of bifid ureter: apropos of a case].

The Authors report on a case of blind-ending ureter. A young woman (29 years old) underwent surgery because of recurrent urinary tract infections and left loin pain. The operation consisted in a radical resection of the blind branch together with Coen's operation for the coexistence of vesicoureteral reflux. Authors' goal was to review the international Literature on this rare pathology pointing out their opinion on the existing terminology which is still far from being clear and definite
