[Perforation of primary non-Hodgkin's lymphoma during chemotherapy. Clinical evaluation and therapeutic strategy]. / Perforazione di linfoma non-Hodgkin del cieco dopo chemioterapia. Valutazione clinica e strategia terapeutica.

Primary cecal lymphoma are very rare. The case is reported of an elderly woman having voluntary preliminary chemotherapy with consequent cecum perforation due to tumoral necrosis, some days after the first chemotherapy. The diagnostic, clinical and therapeutic protocol is analysed and stress is laid on the rare clinical cases described. Resection is advisable in the still delimited forms in order to avoid surgical complications due to preliminary chemotherapy and in order to classify precisely the neoplasm.

[Synchronous carcinoma of the colon and rectum]. / Il tumore sincrono del colon-retto.

The incidence of synchronous carcinoma of colon-rectus is rising in relation to a greater oncogenic environmental charge and increased average life expectancy. There is also a risk of not recognising the disease (especially small carcinoma or multicentric neoplasm). After a Literature review, two clinical cases are described by the authors. They recommend an extensive use of preoperative colonoscopy and a careful intraoperative exploration of the viscera. It is also important that patients undergo periodical postoperative endoscopic controls.

[Proposal for anatomo-functional instrumental control of dysfunctional bilio-digestive Roux-en-Y anastomosis]. / Proposta di controllo strumentale anatomo-funzionale di anastomosi bilio-digestiva su ansa defunzionalizzata secondo Roux.

Various techniques are used for the anatomo-functional study of bilio-digestive anastomoses on jejunal loop autonomized according to Roux. Here a transparietojejunal endoscopic investigation is proposed that permits direct sight of the anastomosis, biliary sampling for cultural examination and dilatative type therapeutic manoeuvres, biopsies or extractions of residual stones from the bile ways that would not otherwise be possible without further surgery. A clinical case is reported.

[An unusual feature of Meckel's diverticulum in association with phlegmonous appendicitis and mesenteric cyst. A clinical case]. / Un particolare aspetto del diverticolo di Meckel con contemporanea presenza di flemmone appendicolare e cisti mesenteriale. Caso clinico.

A particular case of Meckel's diverticulum, with phlegmonous appendicitis and mesenteric cyst associated, is presented. The Authors discuss the etiophatology, explaining the anatomic and clinical found situation.

[Immune complex monitoring in Echinococcus infections]. / Monitoraggio degli immunocomplessi nell'affezione echinococcica.

In two patients with hepatic echinococcosis, we studied the in vivo interaction between circulating immune complexes and polymorphonuclear neutrophil surface receptors according to our previously described technique and quantitated the amount of circulating immune complexes by the C1q binding assay. Both tests were positive prior to surgical removal of the cysts, to gradually become negative to weeks later, and are persistently negative at two months after complete asportation. The application of the two tests may be of value in assessing surgical radicality and consequently the prompt disappearance of circulating parasite antigens. In particular, failure of these two tests two turn negative or the occurrence of further, new positivities may suggest either uncomplete eradication of the cyst or reinfection. These immunologic techniques appear to provide a better monitoring of echinococcosis than all the other well-known immunological tests which detect specific immunoglobulins present in serum for a long time and therefore unable to indicate the persistence or the new appearance of the parasite antigens.
