[Blueberry muffin baby. A rare presentation of congenital cytomegalovirus infection]. / Blueberry muffin baby. A presentação rara de infecção congénita por citomegalovírus.

The 'blueberry muffin baby' designation was used to describe the cutaneous manifestations of congenital rubella. The differential diagnosis includes other TORCH infections, blood dyscrasias, neoplasms, or vascular disorders. We present a case of a newborn admitted at birth for presenting disseminated violaceous cutaneous nodules. Pregnancy was full term and without infectious complications, with prenatal diagnosis of restrictive intrauterine growth, hydramnios and suspected esophageal atresia. Maternal serology with no evidence of infection. The newborn blood study showed thrombocytopenia, direct hyperbilirubinemia, elevated transaminases and coagulopathy. During hospitalization he showed progressive hepatosplenomegaly. Skin biopsy showed extramedullary erythropoiesis. Myelogram revealed absence of megakaryocytic line precursors. The molecular analysis for cytomegalovirus in peripheral blood and bone marrow was positive. Cerebral ultrasound examination revealed bilateral calcifications and periventricular hyperechogenicity. The placental anatomopathological exam showed features suggestive of cytomegalovirus infection. On the fifth day of life was initiated ganciclovir. This case presentation is intended to emphasize that although it is a rare manifestation, congenital cytomegalovirus infection should be considered in the differential diagnosis of 'blueberry muffin baby'.

A prospective study on incidence of bacterial infections in portuguese dialysis units.

BACKGROUND: Viral infection has been the main epidemiologic concern in the hemodialysis unit; however, bacterial infection is responsible for more than 30% of all causes of morbidity and mortality in our patients, vascular access infection being the culprit in 73% of all bacteremias. METHODS: A prospective multicenter cohort study of bacterial infections incidence, conducted from January to July 2004 in five hemodialysis units, to record and track bacterial infections, using a validated database from CDC's Dialysis Surveillance Network Program. RESULTS: 4,501 patient-months (P-M) were surveilled, being dialyzed through a native fistula (AVF) in 60.6%, a graft (PTFE) in 31.3%, a tunneled catheter (TC) in 7.6%, and a transient catheter (C) in 0.5%. As target events, we registered 166 hospitalizations - 3.7/100 P-M (2.2/100 P-M in patients with AVF, 4 in PTFE, 9.9 in TC, and 19 in C), and 182 intravenous antibiotic courses. Of these 182 antibiotic treatments, 47.8% included vancomycin, only 30% had blood cultures drawn pretreatment, and only 36% were positive. We recorded 98 infections at the vascular access site 2.18/100 P-M (0.95 in AVF, 1.6 in PTFE, 12.6 in TC, and 42.85 in C) and 2.13 infections/100 P-M at other sites. The isolated microorganisms were Staphylococcus epidermidis in 40.1%, Staphylococcus aureus in 30.1%, Pseudomonas in 13.3%, and Escherichia coli in 3.3%. Although we found a diversity of practice patterns, the number of target events (8.4/100 P-M) and the bacterial infections incidence (4.31/100 P-M) were remarkably homogeneous in the five centers. CONCLUSION: (1) High incidence of bacterial infections, causing major morbidity; (2) infectious risk is vascular access type-dependent, with dramatic rise in catheters; (3) underutilization of blood cultures to orient diagnosis and therapy, and (4) high rates of vancomycin prescription.
