A case of postvaricella cerebral angiopathy with a good outcome in a child.

Cerebral vasculopathy is a serious but uncommon complication of varicella-zoster-virus (VZV) infection. Diagnosis is based on a recent history of VZV infection, signs and symptoms of transient ischemic attack or stroke, and vascular anomalies on neuroimaging. We report a case of postvaricella cerebral angiopathy in a 5-year-old child, who was admitted after three episodes of transient right hemiplegia, each one lasting a few minutes. He had contracted chicken pox, the month prior to admission. Brain magnetic resonance imaging showed hyperintense signals in the left lenticular and caudate nuclei, which can be considered to be a result of vasculopathy.

Characterization and DNA Plasmid Analysis of Ropy Pediococcus spp. Strains Isolated from Basque Country Ciders.

Ten strains of Pediococcus spp. causing ropiness were isolated from Basque Country spoiled ciders and characterized with regards to growth at different pHs, temperatures, and ethanol and SO2 concentrations. They grew well at pHs above 3.7 and failed to grow at temperatures over 37°C. In addition, they were tolerant to 10% ethanol and to 15, 25, and 50 mg/l total SO2 (pH 3.8). A selected ropy strain was used to carry out plasmid DNA analysis; the agarose gel pattern showed the presence of 6 bands of plasmid DNA. Plasmid-curing experiments with ethidium bromide and novobiocin suggested that the ropy phenotype was encoded by plasmid DNA. In addition, this nonropy strain lost its resistance to oleandomycin after curing trials.

Aspectos serologicos de la relacion virus herpes y cancer cervico-uterino / Serological aspects of the relation herpes virus and cervico-uterine neoplasms

Se investiga la presencia, nivel y tipo de anticuerpos anti-virus herpes simples 1 y 2 (HSV-1 y HSV-2) en 112 mujeres portadoras de neoplasia cervical y 48 portadores de otros tipos de neoplasias.En ambos grupos se detecto una distribucion semejante de anticuerpos anti HSV-1 (98% de seropositivas). En cambio, frente al HSV-2 la distribucion de anticuerpos es claramente diferente: un 82,1% de las pacientes con cancer cervico-uterino presentan anticuerpos anti HSV-2 frente a 54,1% de seropositivas en el grupo de pacientes control. Al analizar el tipo serologico predominante en las pacientes estudiadas se detecta un predominio de anticuerpos anti HSV-2 en 47,3% de las portadoras de cancer cervical, y en 31,2% de enfermas con otras neoplasias
