[Mental deficiency associated with a fragility of the X chromosome]. / Deficiencia mental asociada a fragilidad del cromosoma X.

Fragile X chromosome was studied in 44 male and 9 female children, affected of mental retardation. In 10 males fragile X was positive. All this patients presented mild mental deficiency with and IQ from 55 to 75. Behaviour was generally hyperkinetic except one autistic boy. Most frequent dysmorphic signs were increased head circumference and prominent large ears. Family history for mental retardation was positive almost in all cases. High percentage of children with fragile X syndrome (22.7%) encountered among male patients suggest convenience of screening, for these anomaly, of all boys affected of mild mental deficiency and all those with an autistic behaviour although lacking of dysmorphic characteristics. This will allow to know more on etiology and to offer genetic counseling to families. Although study in girls was negative, authors believe it is interesting to screen fragile X because some females with border line retardation present this chromosomic anomaly.

[The cardiorespirogram in the first 12 hours of life. Relation to the form of termination of labor]. / Estudio del cardiorrespirograma en las primeras doce horas de vida. Relación con la forma de terminación del parto.

Cardiorespirography is a method of monitoring which establishes a correlation between cardiac and respiratory activity. During the first twelve hours following birth cardiorespirographic parameters undergo a series of evolutionary modifications, becoming stable between the sixth and twelfth hours. Authors analyse how the manner in which birth is terminated influences parameters during first twelve hours. In the case of caesarean births they find only one instance of diminishing accelerations during the first hour, and in spontaneous births, a reduced number of instances of decelerations are registered during first and sixth hour. They believe that these findings are due to drugs administered during birth rather than to the manner in which this was achieved.

[Cardiorespirographic parameters in the first 12 hours of life. Influence of the administration of thiopental and diazepam plus thiopental on labor]. / Parámetros cardiorrespirográficos en las primeras doce horas de vida. Influencia de la administración de tiopental y diacepam más tiopental en el parto.

Cardiorespirographic parameters undergo a series of evolutionary modifications during first hours of life, becoming stable between the sixth and twelfth. The authors analyse how these parameters are influenced by the administration to the mother of thiopental and diazepam plus thiopental during birth. They observed a significant reduction, during the first hour after birth, in the range and frequency of accelerations in the newborn babies whose mothers had been administered one of the drugs. Also, they observed a greater number of cases of decelerations in the newborns who were given drugs. No significant differences were observed in other parameters, and after the twelfth hour no differences were observed at all.

[Sudden death syndrome of the nursling. Review of cases and current status of research]. / Síndrome de la muerte súbita del lactante. Revisión casuística y estado actual de las investigaciones.

In addition to analyse fourteen sudden infant death syndrome cases authors review main epidemiologic and morphologic knowledges, pointing out up to date investigations on the fields of biochemistry and ultrastructural morphology.

[Craneopharyngioma in children (author's transl)]. / Clínica del craneofaringioma en la infancia

Clinical findings in the initial and developed stages were studied in 33 cases of craneopharyngiomas in children under sixteen. A predominance of intracraneal hypertension symptoms and sight defects over endocrine symptoms was discovered; the latter appearing later on or only being detected after exhaustive studies.
