[Pseudosarcoma of the urinary bladder. Report of a case]. / Pseudosarcoma della vescica urinaria. Studio di un caso.

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.

Ischemic colitis with chronic stenotic evolution.

The authors describes a case of ischemic chronic stenosis of colon after aneurysmectomy. They consider eziopatogenesis, clinical aspects and differential diagnosis with other causes of large bowel stenosis. They illustrate on therapeutic sequence after examination of recent literature.

[Nephrogenic metaplasia. A particular clinical and anatomopathologic entity]. / La metaplasia nefrogenica. Una particolare entità clinica ed anatomopatologica.

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.

[Endoscopic surgery of chronic venous insufficiency (CVI)]. / La chirurgia endoscopica nell'insufficienza venosa cronica (IVC): risultati preliminari.

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.

[Role of total thyroidectomy in benign multinodular benign goiter]. / Il ruolo della tiroidectomia totale nella tireopatia nodulare plurifocale benigna.

The Authors report a review of the Literature and their personal series to evaluate the role of total thyroidectomy in the surgical management of non-toxic multinodular goiter. On the basis of the data obtained, the Authors consider total thyroidectomy the therapy of choice for this pathology.

[Blind-ending branch of bifid ureter: apropos of a case]. / L'uretere bifido a branca cieca: a proposito di un caso.

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.

[Ambulatory surgery of varices: our experience]. / La chirurgia ambulatoriale delle varici: nostra esperienza.

The Authors, on the basis of their experience with 196 patients aged from 18 to 45, affected by relapsing varicose veins, stress the advantages of the outpatient treatment according to Muller's technique. For these lesions excellent aesthetic and functional results, easy surgical technique, low incidence of complications, prompt resumption to work were registered.

[Renal microcarcinomas: a particular clinical entity]. / I microcarcinomi renali. Una particolare entità clinica.

According to the possibility of an early diagnosis, related to diagnostic imaging and predictive indexes such as DNA and vascular permeability, in the presence of a low grade-low stage tumor, and with the support of the Literature, the Authors hypothesize an increasing applicability of conservative surgery in the management of small renal carcinomas.

[Ambulatory phlebectomy: our experience]. / La flebectomia ambulatoriale: nostra esperienza.

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.

[Male infertility due to varicocele: their diagnosis and treatment. Our experience]. / L'infertilità maschile da varicocele: diagnostica e terapia. Nostra esperienza.

The Authors have examined, over a period of two years, 110 patients presenting with varicocele and infertility. Varicocele has an incidence of 40% in male sterility, causing oligozoospermia and asthenospermia. Patients first underwent non-invasive tests such as Doppler and echo-Doppler tests. According to the Authors experience, Doppler speedometry is decisive for the diagnosis of both idiopathic and subclinical varicocele, for the post-operative control of microsurgical anastomosis, and for the intra-operative detection of accessory spermatic veins. The surgical technique used by the Authors is the modified Palomo technique, but other techniques are investigated as well. Post-operative results, concerning both spermiogram and relapses are also evaluated.

[Tietze's syndrome: importance of differential diagnosis and role of CT]. / Sindrome di Tietze: importanza della diagnostica differenziale e ruolo della TC.

A case of Tietze's syndrome is reported. A 55-year-old woman had experienced left anterior chest pain and tender swelling of the left second costosternal junction for one month. CT showed a focal enlargement of the left second costal cartilage with partial calcification. Six months later a complete recovery was registered and a second CT scan was negative. These clinical and CT findings are consistent with Tietze's syndrome.

[A case of renal infarction: clinical and anatomic contribution]. / Un caso di infarto renale: contributo clinico ed anatomico.

A case of renal infarction presenting with acute abdomen is reported. Due to the extended renal damage nephrectomy was performed. Macroscopic appearance of the kidney (prevalent cortical vascular infarction) and of the surrounding tissues (retroperitoneal edema and abdominal ascites) suggested a comparison with epidemic haemorrhagic fever. Vascular supply to the kidney, in such cases, depends on the perforating arteries which may increase in number and size.
