[Congenital syphilis and syphilitic mothers. Survey of the past 10 years]. / Sífilis congénita versus de madre luética. Revisión de los últimos 10 años.

Two hundred and sixty-two newborn infants, born to mothers with a positive syphilis serology, have been studied. Twenty-six newborn infants had congenital syphilis and two hundred and thirty-six were considered as newborn infants from syphilitic mothers. This study has demonstrated that the newborn infants with congenital syphilis have been born to mothers with greatest risk factors. Newborn infants with congenital syphilis born to mothers on treatment during the pregnancy had a milder case of congenital syphilis than newborn infants born to mothers without treatment during the pregnancy. A diagnostic test for the treatment in these newborns has been proposed; if the test score is less than 5, we are dealing with a child of a syphilitic mother that does not need treatment and if the test results are higher than 5 we can confirm the diagnosis of congenital syphilis and immediate treatment must be started.

[Non-neurologic manifestations in hypoxic-ischemic disease in newborn infants]. / Manifestaciones extraneurológicas de la enfermedad hipóxico-isquémica en el recién nacido.

The aim of this work is to determine the most important factors related with to the appearance of systemic abnormalities in hypoxic-ischemic illness after neonatal asphyxia. A total of 145 full-terms neonates affected by hypoxic-ischemic encephalopathy (HIE), were studied. Forty-seven infants (32.4%) presented systemic abnormalities (arterial hypotension and acute renal failure, pulmonary abnormalities or necrotizing enterocolitis). A relationship between the presence of HIE and the appearance of extra-neurological abnormalities was found (p = 0.0174). An increase in erythroblasts was related with to the appearance of extra-neurological abnormalities (p = 0.0127).
