Chronic hepatitis C virus (HCV) infection exists in a large proportion of patients undergoing renal transplantation. Nowadays it is not considered to be an absolute contraindication to transplantation; however, it is associated with an increased risk for the patient and accounts for a shorter half-life of the renal allograft. We present three transplant recipients who displayed serious hepatic dysfunction after renal transplantation due to an HCV infection. In two of these cases, the liver biopsies established the diagnosis of FCH. In the third case, the liver biopsy was compatible with the early stages of FCH. All patients were started on peg-interferon alfa 2-b and ribavirin with subsequent normalization of hepatic function and early complete viral responses.

Setting: Burkitt’s lymphoma is a rare form of cancer and is an extremely rare diagnosis during pregnancy. This form of lymphoma is a very fast growing B cell neoplasm and chemotherapy is the treatment of choice for the disease in all its stages. Case report: The authors describe the case of a Caucasian 40-year-old nulliparous woman, with previous known Epstein–Barr virus infection, that presents at 28 weeks gestation with supraclavicular adenopathy and multiple bilateral breast nodules, in which biopsy showed non-Hodgkin lymphoma, Burkitt’s type. Discussion: There are few described cases of Burkitt’s lymphoma during pregnancy and in general the outcomes have been poor. In most of the cases, the patients were not treated by current standards or instead had a late diagnosis. This neoplasia is the most rapidly progressive human tumor, and any delay in initiating therapy can adversely aVect patient’s prognosis. The authors discuss treatment options in pregnancy and its perinatal implications.

Fulminant myocarditis associated with influenza A virus is exceedingly rare, with only a few cases reported in the literature. We describe a previously healthy 10-year-old boy, with a three-day history of flu-like symptoms without antiviral treatment. He was hospitalized with dehydration and hypothermia in the context of persistent vomiting, when he suddenly developed heart failure secondary to fulminant myocarditis. Despite aggressive management, including circulatory support and cardiopulmonary resuscitation measures, the patient died of cardiogenic shock. The postmortem histopathology was compatible with a multisystem viral infection with myocarditis and pulmonary involvement, and H1N1v polymerase chain reaction was positive. The prevalence of influenza-associated fulminant myocarditis remains unknown. Findings reported in the literature raise the possibility that the novel H1N1 influenza A virus is more commonly associated with a severe form of myocarditis than previously encountered influenza strains.
