Piriform Aperture

The piriform aperture (PA) is the skeletal aperture located in the middle part of the face. There are many variations in morphometric measurements of nasal bones, piriform apertures and their shapes in different population. Objective of present study was to study morphological and morphometric features of nasal bone and piriform aperture. Adult human skulls available from collection of dried skulls were used for study purpose. Skull bones of unknown age and sex were obtained. Height, width of nasal bone, height, upper and lower width of piriform aperture, shapes of nasal bone and piriform aperture were observed. Height, upper width and lower width of piriform aperture were greater in male as compared to female. This difference was not statistically significant for upper width of piriform aperture (p=0.49) and for lower width of piriform aperture (p= 0.65) while the difference in height of piriform aperture was statistically significant. (p <0.0001).Differences in Height and width of nasal bone were not statistically significant among male and female nasal bones. Most common shape of nasal bone observed was Type A followed by Type B and C. Most common shape of piriform aperture was triangular to oval (50.00) in both the gender. Majority finding of the present study are in concordance with Indian population studies while significant differences have been noted in comparison to the morphometric measurements of Turkish, Korean, Brazilian and Anatolian population. These variations might be because of differences in ethnicity.

Objective. To evaluate the pre- and postnatal outcomes of euploid fetuses with aplasia/hypoplasia of the nasal bones (NB). Methods. We have made the catamnestic monitoring of children with a normal karyotype, who had been prenatally detected NB aplasia or hypoplasia (less than 5 perentile) at 11–24 weeks of gestation at ultrasound screening in the period between 2006–2015 years. Our study included a selection of 242 fetuses with NB aplasia or hypoplasia, in 128 (52.8 %) of them the NB was not visualized or appeared as an echogenic dot only. Results. Among all 63 fetuses with NB aplasia (absence or looks as an echogenic dot) in the 1st trimester in 24 (38 %) cases chromosomal abnormalities (CA) were found (including T21 — 15 (62.5 %) cases). Other 39 (61.9 %) fetuses had a normal karyotype. Among 65 fetuses with NB aplasia, examined in the 2nd trimester of gestation 12 (18.4 %) cases of CA were detected (one fetus with T21 had the only one ultrasound marker – isolated NB aplasia), 53 (81.5 %) fetuses had a normal karyotype. 62 mothers of the euploid fetuses with NB aplasia had been surveyed. We have received and analyzed 31 (50 %) responses. In 16 cases of euploid fetuses with NB, aplasia pregnancy outcome was adverse or relatively unfavorable, only 5 (31.2 %) fetuses of them had isolated NB aplasia. In other cases healthy full-term infants were born, who showed normal height and weight indexes, physical and psychomotor development observed in age from 0 to 10. Conclusion. In 51.6 % fetuses and children prenatally had aplasia of the nasal bone was marked by unfavorable pre- or postnatal outcome, according to the survey of their mothers.

AbstractThis study aimed to investigate the relationship between genetic ancestry inferred from autosomal and Y chromosome markers and HLA genotypes in patients with Type 1 Diabetes from an admixed Brazilian population. Inference of autosomal ancestry; HLA-DRB1, -DQA1 and -DQB1 typifications; and Y chromosome analysis were performed. European autosomal ancestry was about 50%, followed by approximately 25% of African and Native American. The European Y chromosome was predominant. The HLA-DRB1*03 and DRB1*04 alleles presented risk association with T1D. When the Y chromosome was European, DRB1*03 and DRB1*04 homozygote and DRB1*03/DRB1*04 heterozygote genotypes were the most frequent. The results suggest that individuals from Maranhão have a European origin as their major component; and are patrilineal with greater frequency from the R1b haplogroup. The predominance of the HLA-DRB1*03 and DRB1*04 alleles conferring greater risk in our population and being more frequently related to the ancestry of the European Y chromosome suggests that in our population, the risk of T1D can be transmitted by European ancestors of our process miscegenation. However, the Y sample sizes of Africans and Native Americans were small, and further research should be conducted with large mixed sample sizes to clarify this possible association.
