Zimmermann-Laband syndrome: further clinical delineation.

Zimmermann-Laband syndrome (ZLS) is an autosomal dominant disorder characterized by gingival fibromatosis, absent or dysplastic distal phalanges, vertebral defects, hepatosplenomegaly, hypertrichosis and sometimes mental retardation. We describe two unrelated patients, a girl aged 9 years and a boy 11 months whose clinical and radiological findings permit us to diagnose the ZLS. Body overgrowth, present in both patients, was identified as a main clinical feature not previously reported as well as the presence in neuroimaging studies of a cavernous hemangioma on the frontal and the left cerebellar regions in the boy.

Parenting of young children by fathers in Mexico and the United States.

In the present study, the parenting practices and developmental expectations were examined in a sample of 96 fathers from Mexico and the United States, all with children from 1 to 5 years of age. The selection of fathers from both countries was controlled for the family's socioeconomic status (SES) and for the age and gender of their children. The Parent Behavior Checklist, a 100-item rating scale was used to measure parents' developmental expectations and their discipline and nurturing practices.

[Cross-cultural comparisons of the Parenting Inventory for Adults and Adolescents].

This paper compares the normative point count of the Parenting Inventory for Adults and Adolescents (PIAA) with the points of the fathers of a family (n = 336) and adolescents (n = 357) in the city of Guadalajara. The comparisons were studied in the four dimensions of paternity which have proven clinically and experimentally valid for detection of child abuse and maltreatment. An analysis of the points obtained by fathers of children in private and public schools, as well as the points acquired by Mexican female adolescents were compared with white and black adolescents (in USA), as well as pregnant and non-pregnant ones.

Is the matching familiar figures test a measure of cognitive style? A warning for users.

A probabilistic model of reflection-impulsivity as measured by the Matching Familiar Figures Test (MFFT) is presented and tested on 77 fourth graders. In testing the model two groups emerged, a random response group (n = 22) and a cognitive response group (n = 55), who use the evaluation process. Correlations among latencies, total errors, initial errors, school-scores, and IQs were compared for our total sample and the two groups.

Children's human figure drawings and impulsive style at two levels of socioeconomic status.

The relationship between children's reflection-impulsivity styles and their human figure drawings was examined for a sample of Mexican children of middle (n = 97) and low (n = 110) socioeconomic status. Drawings were scored for Developmental, Emotional, and Impulsivity indicators. As in previous research with American preschoolers, the drawings of 23 Mexican preschoolers did not correlate with the styles; however, significant relationships between the styles and Impulsivity scores of older children of low status (n = 87) were also found, suggesting that, when a higher-level of impulsivity is present in a population, a relationship between styles and drawings may be observed.

Response of rats to seizure stimulus modified by feeding.

Wistar (W) and Sprague-Dawley (S.D.) rats responded differently to electroshock and metrazole test when fed with two diets (A and B).

Lead exposure in two pottery handicraft populations.

Lead poisoning studies were carried out in the populations of two potter towns in the State of Jalisco, Mexico. The first population in Tonalá included 198 people who use lead monoxide (PbO) in making pottery. The second population in El Rosario included 187 people who do not use any lead salt in the pottery-making process.

[Quantitative analysis of the electroencephalographic activity during human sleep].

Correlation of hormonal changes and EEG activity requires objective measurements to define the behavior of the different frequency bands during sleep. With this purpose, EEG activity of six healthy male volunteers (19-22 years) was recorded throughout all night during spontaneous sleep. The C4-left mastoid EEG combination was channeled to a frequency analyzer with four band pass filters (beta, alpha, theta, and delta) using a one minute averaging interval.
