Transcutaneous carbon dioxide measurements in the fetus during labor.

Continuous transcutaneous carbon dioxide partial pressure (tcPco2) was monitored in 40 spontaneous labors. The electrode was attached by glue fixation. An interpretable tracing was obtained in 36 cases.

[Results of an experiment in systematic prenatal screening for neural tube malformations by assay of alpha fetoproteins in dried blood samples (12,480 pregnancies)].

Measurement of alpha-fetoprotein (AFP) in eluate of dried blood was carried out in 12,480 pregnant women, between the 10th and 30th weeks of amenorrhea. In 348 cases, AFP level was greater than normal (greater than 99th centile). 225 control measurements were performed (123 women dropped out of the study).

[Practical evaluation of some discriminant criteria for the dermatoglyphic diagnosis of twin zygosity].

In practice identical twins are sometimes to be distinguished from non identical on physical resemblance what is mainly subjective. Quantitative criterias combined into a simple formula would offer a quick, objective and practical tool. This brought us to elaborate a discriminant score based on numerical dermatoglyphic data either used alone or introduced into given mathematical expressions.
