Waldenströms macroglobulinaemia and intravenous contrast media.

In vivo and in vitro studies have been performed in a group of patients with immunoproliferative diseases to evaluate the risk of serious reactions due to serum jelling after intravenous injection of iodinated contrast media. Sol-jell convertion and/or turbidimetric variations have not been observed when either sera or plasmas have been mixed with variable amounts of a methylglucamine salt of ioglycamic acid (MGI) and other compounds. In addition, no side-effects have been clinically recorded in three patients with Waldenströms macroglobulinaemia (WM) whose sera and/or plasmas had been studied in vitro, when they have been submitted to intravenous contrast examinations. The results suggest that there is not an evidence of a relationship between iodinated contrast media and fatal reactions due to sol-jell alterations in patients with WM and therefore a radiological examination using contrast media may be carried out in those patients.

[Fournier syndrome: multidisciplinary approach].

Fournier's gangrene, a form of necrotizing fasciitis, is an uncommon, fulminant, rapidly progressing subcutaneous infection of the scrotum and genito-perineal region, and may occur in all age groups. Most cases involve a mixed synergistic infection of aerobic and anaerobic bacteria, and occur as a result of one of this mechanisms: local trauma, extension from a perineal, periurethral or ischiorectal infection. It is associated with a high mortality rate. Predisposing factors included diabetes mellitus, steroids or chemotherapy, alcohol abuse, malignancy and radiation therapy. This disease requires prompt treatment: early diagnosis, antibiotic therapy, nutritional support, immediate extensive surgical debridement and hyperbaric oxygen therapy. The use of etherologue serum is a valuable adjunct in the therapy of Fournier's gangrene. We report a case of Fournier's syndrome treated with etherologue serum immuno-therapy, together with the conventional multidisciplinary approach. The postoperative course was uneventful and the patient was discharged on day 50 post intervention in good general conditions. The 3 years follow-up showed no recurrence of the disease. In conclusion we remark that the survival can be improved in patients with Fournier's gangrene by multidisciplinary approach.
