Yersinia is an enterobacterium that causes acute enterocolitis, pseudoappendicitis and sepsis. Some patients suffer from post-infectious immunopathological complications, such as erythema nodosum and yersinia arthritis, which are well known. Less information exists concerning the erythema multiforme-like yersinia exanthema, which is a distinctive dermatological disorder with target lesions localized predominantly on the neck, shoulders and arms. These lesions, which may be smaller but often are larger than the iris lesions in conventional erythema multiforme, tend to coalesce into plaques and reveal a papulovesicular component at their periphery. In our cases the exanthema was associated with a conjunctivitis, especially of the nasal part of the conjunctiva. This exanthema can be induced by yersinia enterocolitica, serotype O-3 and type O-9, at least in Europe, whereas serotype O-8 prevails in North America. The most helpful diagnostic criteria are serological data. However, it is crucial to remember that Widal's agglutination reaction gives rise to high titres, whereas the results of the complement-fixation test are often not reliable.

A long-term hemodialysis male patient was known to have systemic iron overload due to regular blood transfusions. As he was suspected to have aluminum overload, he received a single intravenous administration of desferrioxamine (that supported the hypothesis). Four days later, he became highly febrile with no focus of infection on physical examination. All blood cultures yielded Yersinia enterocolitica. The aim of this case report is to recall the potential risk of Yersinia sepsis in iron overload patients treated with desferrioxamine, even for a short time. The diagnosis should be suspected even in the absence of digestive symptoms, leading to immediate desferrioxamine withdrawal and antibiotic therapy.

A 50-year-old man with diabetes was found to have sepsis with multiple small hepatic abscesses secondary to Yersinia pseudotuberculosis which were detected by computed tomography (CT) scan. Sepsis with Y. pseudotuberculosis is uncommon but usually seen in patients with underlying liver disease. Those patients with liver abscesses invariably have multiple small abscesses. Widespread use of CT scanning is likely to uncover more cases of hepatic microabscesses; in the appropriate clinical setting, Y. pseudotuberculosis should be considered as a possible cause.

Septicemia is a rare but serious complication of infection with Yersinia enterocolitica (Y.e.). Seven cases of Y.e. septicemia are presented. Five of the patients had no underlying disease predisposing to septicemia. Five patients displayed recurrent episodes of septicemia, despite treatment with recommended doses of antibiotics to which the isolates were sensitive in vitro. One patient developed endocarditis which required surgical replacement of the aortic valve. Other clinical manifestations were arthritis, diverticulitis and pulmonary abscesses. The outcome was fatal to 3 elderly patients. The serological response to Y.e. was followed by tube agglutination and a diffusion-in-gel enzyme-linked immunosorbent assay. One patient, with a benign course of illness, had transient elevated Y.e. antibody titres, while the 3 cases with a protracted disease showed sustained antibody responses for 6-18 months. Blood isolates of Y.e. had ordinary virulence characteristics identical to fecal isolates and produced extracellular beta-lactamase. All isolates were sensitive in vitro to trimethoprim-sulfamethoxazole, mecillinam, piperacillin, cefotaxime, ceftazidime, chloramphenicol and gentamicin. The lowest MIC values were recorded for mecillinam. Full synergistic activity was demonstrated when mecillinam was combined with trimethoprim-sulfamethoxazole, cefuroxime or rifampicin.

The purpose of this communication is to report the occurrence of early-onset Pseudomonas aeruginosa sepsis and Yersinia enterocolitica neonatal infection. This case serves as a reminder of the changing spectrum of neonatal septicaemia.

Two cases of Yersinia enterocolitica septicemia in two splenectomized children with thalassemia major are reported. Human Yersinia enterocolitica septicemia is an uncommon condition, but its frequency may increase in patients having debilitating diseases or blood disorders, as well as a consequence of the splenectomy. Some brief considerations on the pathogenetic factors yielding, to severe infections in splenectomized thalassemic children are discussed. The high number of thalassemic people in Italy makes necessary an early diagnosis in case of septicemia. Particularly important is the blood culture, because of the slowness of the microbic development in stools.

Micronodular pneumonia and persistent sepsis with mild symptoms caused by Yersinia enterocolitica serotype 3 is described. Two of 4 patients had pneumonia as their only clinical manifestation, while the others had diarrhea as well. Pneumonic changes disappeared quickly during antimicrobic therapy. The course of the disease was fundamentally different from septicaemias caused by other gram-negative bacteria.

A patient with fatal Yersinia enterocolitica sepsis was seen recently in our intensive care unit. The patient had received two units of packed red blood cells during a surgical procedure. Cultures of the donor blood yielded Y enterocolitica, and a whole-organism enzyme-linked immunosorbent assay of the donors' sera suggested a recent infection with Y enterocolitica in an asymptomatic donor. Though rare, Y enterocolitica, which can grow at the cold temperatures of refrigerated blood, should be considered as a possible source of sepsis following blood transfusion.

A case of severe Yersinia enterocolitica septicemia in a hemodialysis patient receiving desferrioxamine (DFX) therapy is reported. The association between systemic yersiniosis and DFX chelation therapy is reviewed. The increasing application of DFX chelation, in iron overload states and for aluminium overload in dialysis patients, provides an increasing number of patients at risk for this unusual drug side effect. An awareness of the association between Yersinia sepsis and DFX therapy allows appropriate therapeutic intervention which may prove lifesaving.

Our purpose was to study prospectively the causes, routes of infection, and frequency of catheter-related sepsis in patients on total parenteral nutrition. From January 1981 to January 1984, cultures of 135 subclavian catheters from 135 adult patients were done by quantitative and semiquantitative methods. Twenty patients (14.8%) had catheter-related sepsis. Fourteen episodes (70%) stemmed from an colonized hub. Skin infection (Staphylococcus aureus, 2 cases), total parenteral nutrition mixture contamination (Enterobacter cloacae, 2 cases), and hematogenous seeding of the catheter tip (Yersinia enterocolitica, 1 case, and Streptococcus faecalis, 1 case) accounted for the remaining six septic episodes. The catheter hub is, in our experience, the most common site of origin of organisms causing catheter tip infection and bacteremia.
