Prenatal sonographic appearance of foramina parietalia permagna.

Foramina parietalia permagna (FPP) is an extremely uncommon congenital defect, inherited as an autosomal dominant condition. Its characteristics are two symmetrical orifices in the parietal bones (not of fixed size) on both sides of the midline. This defect does not affect either the psychic or the physical development of the affected person. This paper describes the sonographic appearance of FPP in utero as an enlargement of the posterior fontanelle.

Progestin challenge test in postmenopausal patients.

OBJECTIVES: The purpose of this study is to analyze the characteristics of patients identified with the progestin test. METHODS: We administered the progestin challenge test to 157 postmenopausal women and compared the characteristics of the patients who bled, with those who did not. RESULTS: Bleeding occurred in 14.01% of cases and we found that the number of patients who bled were significantly and independently more overweight, had higher levels of plasma estradiol, had a clear presence of superficial cells in the vaginal epithelium and had been menopausal for fewer years than those who did not bleed. CONCLUSIONS: We concluded that the test identifies women at risk from hormone-related endometrial cancer.

Prenatal ultrasound semiography of anencephaly: sonographic-pathological correlations.

A better understanding of the ultrasound findings in each of the different types of fetal anencephaly can help to reduce the number of false-negative diagnoses of this condition during the prenatal period. Errors in the estimation of the remaining cerebral tissue (angiomatous stroma, area cerebrovasculosa) can cause false-negative diagnoses or diagnostic confusion with cases of microcephaly or incomplete ossification of the cranial vault. In a retrospective study, 30 fetuses with anencephaly (diagnosed at 13-38 weeks of gestation) were grouped, in terms of their ultrasound results, according to the Nanagas classification. The ultrasound diagnoses were then correlated with those found through autopsy, to identify any errors in the ultrasound classification.

[Prenatal diagnosis of holoprosencephaly with postaxial polydactyly, cardiopathy with normal karyotype].

Holoprosencephaly is a malformation complex, in which the foetal forebrain (prosencephalon) fails to cleave. The aetiology of holoprosencephaly is heterogeneous. In the last years, a new malformation syndrome has been described, including holoprosencephaly, postaxial polydactyly, congenital heart defects and normal karyotype. In this report, a new case of this syndrome, prenatally diagnosed, is discussed, based on ultrasound and foetal blood sampling. The important implications are pointed out in relation to adequate genetic counselling.

Ultrastructure of the oviductal mucosa of the rat. III. Basal and peg cells.

In an E.M. analysis of the rat oviduct the authors report the morphology of the so-called indifferent basal cells and peg cells. The hallmark of the former are desmosomes and clear cytoplasm; these elements may detach themselves from the basal membrane, migrating towards the lumen and showing prominent ciliogenesis. Peg cells appear to be the morphological image of necrobiotic cells, either ciliatd or secretory.
