Pediatricians and obstetricians should be aware of the possibility of this infectious disease when examining newborns with fever. These observations suggest that antenatal maternal screening for S. dysgalactiae subsp. equisimilis should be considered.”
“The magnetoplasmon spectrum of two-dimensional electron

gas systems with both Rashba and Dresselhaus spin-orbit interactions is investigated theoretically. The coexistence of the two types of spin-orbit interactions leads to resonant Volasertib mw splittings of the collective excitation modes and makes the magnetoplasmon spectrum anisotropic with respect to the direction of the wave vector. The anticrossing gaps in the magnetoplasmon spectrum vary with the angle of the wave vector and reach their extrema at several fixed directions. Such anisotropic splittings could be used to evaluate the relative strength of the Rashba and Dresselhaus spin-orbit interactions in two-dimensional electron systems.

“Recurrent cytomegalovirus (CMV) infections commonly occur after kidney transplantation. We

studied the impact of secondary prophylaxis and other factors on the risk of CMV recurrence. All kidney transplant recipients between 2004 and 2009 in our institution were analyzed (N = 254). Patients with CMV infection were included (N = 62). CMV infections were diagnosed with quantitative PCR. CMV D+/R- recipients received selleck 6 months valganciclovir prophylaxis, after which DNAemia was monitored. After treatment, secondary prophylaxis

Smoothened Agonist research buy with valganciclovir was given at the clinician’s discretion for 2-26 weeks and CMV DNAemia was monitored. Altogether 43 reactivations and 19 primary infections occurred. Antiviral treatment with valganciclovir or ganciclovir was given to 45 patients; 34/62 (55%) patients received secondary prophylaxis for mean 62 days (range 14-180 days). CMV recurrence occurred in 14/43 (33%) seropositive patients and in 4/19 (21%) patients after primary infection. In logistic regression, delayed graft function (OR 3.4) and high viral load (> 100 000 copies/ml) at initial diagnosis (OR 5.9) predicted recurrence. Use or length of secondary prophylaxis, CMV serostatus, level of immunosuppression, HLA mismatch, antiviral treatment, or time to clearance of viremia during treatment did not predict recurrence of CMV. CMV recurrences occur commonly despite secondary prophylaxis. High viral load at diagnosis predicted the risk of recurrent CMV infection.”
“Varicella is usually a benign and self-limited disease of infancy and childhood although it has been recognized that it sometimes has severe and life-threatening complications. We report a case of postinfectious purpura fulminans with acquired protein S deficiency following varicella in a 6-year-old child and discuss the underlying mechanism of postinfectious purpura fulminans.
