1/2. Perinatal dengue infection.We report a case of vertical transmission of dengue infection in an infant. The mother's was a term pregnancy with a history of chronic hypertension. She presented with high fever of 3 days duration 5 days prior to delivery. Her initial complete blood count showed platelet count of 64,000/mm3. Dengue hemorrhagic fever was diagnosed 2 days later and symptomatic treatment was given. During labor her platelets dropped to 11,000/mm3 and platelet concentrate was given. cesarean section was performed due to prolonged second stage of labor. Her infant was normal at birth except for petechiae on the left thigh. The child's platelet count was 34,000/mm3 and low grade fever was detected on the first day. Clinical sepsis was suspected and antibiotic treatment was started and continued for 4 days until all the cultures came back as negative. Both mother and her baby made an uneventful recovery and were discharged 6 days after delivery with normal platelet counts. Maternal blood was positive for IgM antibody to dengue virus. Both cord blood and the baby's blood were positive for dengue virus serotype 2 by PCR.- - - - - - - - - - ranking = 1keywords = petechiae (Clic here for more details about this article) |
2/2. Dengue hemorrhagic shock in the western hemisphere.A 39-year-old man after visiting an endemic dengue area during a local outbreak developed a febrile illness complicated by skin petechiae, bleeding, shock, hemoconcentration, and death. The presumptive diagnosis of dengue was made based on hemagglutination inhibition and complement fixation titers in a single sample. The serologic evidence and ancillary laboratory findings are compatible with a secondary antibody response.- - - - - - - - - - ranking = 1keywords = petechiae (Clic here for more details about this article) |
