RESUMO
OBJECTIVES: To test the hypothesis that fetal memory persists into the neonatal period. STUDY DESIGN: Forty-one newborns that had been repeatedly stimulated by using fetal vibroacoustic stimulation were compared with 31 controls. The same vibroacoustic stimulator was used for both fetal and neonatal stimulation tests. For the neonatal test the stimulus was applied against the mastoid of the newborn with the interposition of a specifically designed solid-liquid interface to simulate intrauterine conditions. Student's t-test was used. RESULTS: Neonatal habituation rate (the number of consecutive stimuli applied before a baby stopped responding) was significantly higher in those newborns who had not participate in the fetal habituation study (7.0+/-5.4 stimuli) than in those who had (4.1+/-4.1 stimuli), p=0.01. CONCLUSIONS: Newborns who were stimulated in utero habituated earlier than those who had not previously experienced the stimulation. These results suggest that fetal memory persists into neonatal life.

El embarazo en pacientes con antecedentes de extrofia vesical corregida quirúrgicamente se ha descrito en la bibliografía y se ha asociado con un riesgo incrementado de infecciones urinarinas, hidronefrosis, incontinencia urinaria o prolapso genital. No existe un criterio uniforme en cuanto a la vía del parto en estas gestantes. Se presenta el primer caso de una extrofia vesical corregida mediante uretorisgmoidostomía y complicada por un prolapso uterino que a su vez se trató quirúrgicamente mediante la suspensión sacra del útero con cincha de goretex. El prolapso recidivó, asociándose un rectocele y en esta situación la paciente consiguió un embarazo espontáneo que cursó de forma fisiológica y finalizó con el nacimiento a término, mediante cesárea, de un niño sano (AU)

Experiments were carried out in order to elucidate a possible role of anterodorsal thalamic nuclei (ADTN) upon adrenal gland function in rats. Bilateral stimulation of ADTN produced a significant decrease in corticosterone concentration (C) in both plasma and adrenal tissue. After exposure to ether vapour, rats with bilateral lesion of ADTN showed that the increase in plasma C was markedly higher than that in the sham lesioned ones. Sham-lesioned stressed rats showed values of adrenal C higher than the values in sham unstressed rats. Whereas, ADTN-lesioned rats showed that adrenal C values were significantly lower than in the lesioned unstressed rats. The concentration of adrenal catecholamines, norepinephrine (NE) and epinephrine (E), in sham-lesioned rats was unaffected by ether stress. In stressed lesioned rats, adrenal glands contained 4 times as much NE and 2 times as much E as did the adrenal glands from lesioned unstressed rats. Our results suggest that the ADTN exert and inhibitory effect on adrenocortical function. They would involved in mediating the effect of stress in adrenal cortex and medulla in rats.
