[Extrahepatic gastrinoma. Report of a clinical case].

Gastrinoma is a rare neoplasia producing gastrina, the hormone responsible of the clinic manifestations related to Zollinger-Ellison syndrome. The localization of gastrinoma is pancreatic or extrapancreatic (usually in Stabile and Passaro triangle). We present a case report concerning an extra-pancreatic gastrinoma not localized in this area and included in a lymph node. This is an extremely infrequent localization (2.4%). There are two different opinions about this localization. Some authors think that this is always a secondary lesion of a small primary neoplasia usually asymptomatic. Other authors think that there are primary lymph nodal gastrinomas that could be safely removed with excision of lymph node. The infrequent localisation of this case induced us to report this experience in order to contribute to the comprehension of this pathology.

[Refractory ascites: a fifteen-year experience with the peritoneovenous shunt].

The authors consider the various causes of ascites and they also develop the concept of refractory ascites. They consider the various possibilities of medical and dietary therapy whose failure constitutes the basis for a surgical approach. In the latter case it is being considered the Peritoneo Venous Shunt (PVS) that employs different types of valves. In the light of their personal experience, matured over a period of 15 years, in which 75 valves were positioned in 64 patients and precisely: 55 valves of Le Veen, 15 Hakim and 5 Denver, it is emphasized that the best results, as for as mortality and morbidity goes, were obtained through careful attention in the preoperative stage and during surgery itself with the privileged use of a Le Veen's valve. For such motives, since in a high percentage of these patients there persists a poor prognosis a year away from the onset of refractory ascites, a PVS seems proposable anyway and even though this will not alter the pathological outcome, there's a clear improvement in the quality of life without precluding any other surgical approach. Finally, the authors outline the possibilities offered by the Transjugular Intrahepatic Portosystemic Shunt (TIPS), as a new original approach for the resolution of refractory ascites.

[Rhabdomyosarcoma. Presentation of a case with abdominal localization].

The Authors report a case of rhabdomyosarcoma observed in a 17-year-old boy. They emphasize that this rare form has an extremely rapid evolution, and in this case was also in an unusual site and of abnormal size. The difficulty of an early diagnosis and the impossibility of radical surgery are also underlined.

[Mesenteric fibromatosis in Gardner's syndrome].

The paper reports a case of mesenteric fibromatosis with familial polyposis, an association which was diagnosed as Gardner's syndrome, and highlights the complications connected to mesenterial desmoid tumours. In addition, the importance of radical surgical therapy of these neoplasias is underlined. Lastly, it is hypothesised that full screening of patients affected by familial polyposis might show a greater incidence of association between widespread polyposis and pathological changes attributable to Gardner's syndrome.

[Ano-rectal candidiasis].

The presence of candida and other fungi was investigated in 300 patients referred with anal problems of diverse aetiology. Candida was present in 13% and played a pathogenic role in about 50% of all positive cultures. It is concluded that cultural tests for fungal pathogens should always be performed in cases of anal itching or burning combined with other anal skin problems.

[Cloacogenic carcinoma of the anus. Description of a clinical case].

A clinical case of cloacogenic anal carcinoma is reported. These neoplasms, deriving from embryonal residuals at different levels of the ano-rectal junction, have a better prognosis than squamous carcinomas; the surgical alternative to abdomino-perineal resection is a simple local exeresis for small tumours that do not invade the muscular layer, with a good radical result as reported by the literature.

[First experiences with trans-rectal echotomography in perianal abscess pathology].

Trans-rectal ultrasound with a 5 MHz probe was used to examine 16 patients who had perianal fistulas and 5 of them underwent one or more surgical explorations. In 11 cases, all surgically checked, sonography was able to demonstrate a pararectal abscess and accurately image the site, size, extension and--in some cases--the fistula itself. It can be advised that, using high frequency probes (7 or 10 MHz), transrectal ultrasound could provide even more exact diagnostic information in anorectal pathology.

[A new ophthalmologic refractometer assisted by a microprocessor].

A new, automated, objective refractometer has been developed in which the examiner looks at the ophthalmoscopic image, while a microprocessor analyzes the data automatically. The results can be displayed as well as printed. The reliability and accuracy of this instrument were evaluated. For spherical or cylindrical powers, 80 to 85% of the refractometer measurements differed from those of subjective refraction by only 0.50 diopter or less. For cylinder axis of eyes with 1.5 diopters or more of astigmatism, the automated and subjective refractions differed by no more than 5 degrees.

[Complications of the surgical treatment of hemorrhoids and its therapy].

Hemorrhoidal disease is a common problem in a proctological ambulatory. Surgery is the best therapy for fourth degree hemorrhoids and the complication rate is 10-20%: postoperative urinary retention etiology is unknown but it may be caused by dysfunction of bladder muscles in response to pain and by an excessive perioperative somministration of fluids; delayed hemorrhage (i.e., 7-10 days postoperative) needs an inpatient care and the treatment ranges from bedside and packing to hemorrhoid pedicle suture ligation in the operating room. Anal stenosis is most commonly a result of a prior improper hemorrhoidectomy: it may be mild, moderate or severe; V-Y and C-anoplasty are the best therapy, also for ectropion. Rubber band Ligation and Sclerotherapy are the most common treatment of internal hemorrhoids: external hemorrhoid trombosis and delayed hemorrage are frequent complications.
