“…Contracted sonographers were obliged to perform a minimum number of scans per year, but a substantial portion of them (29%) did not meet this criterion. We demonstrated a significant correlation between number of scans executed per year and the total audit score, implying the relevance of setting a minimum number of scans, which is in line with an improvement in quality with increasing numbers of nuchal translucency measurements . Moreover, a recent study demonstrated that the level of experience and working volume of the sonographer performing the anomaly scan influence the rates for revision and referral to a center for prenatal diagnosis …”

Ense kal›nl›¤› ölçümü: Kim do¤ru, kim yanl›fl? Amaç: ‹lk trimesterde fetal ense kal›nl›¤› (NT) ölçümü, fetal anöploidi ve kardiyak anomaliler için kestirim olana¤› sunmakta-d›r. Bir tarama belirteci olarak NT ölçümünün yap›lmas› çal›flmalarda tutarl› sonuçlar vermemektedir. NT ölçümü, yüksek gözlemciler aras› ve gözlemciler içi de¤iflkenli¤e sahiptir. Radyologlar, do¤um ve perinatoloji uzmanlar› NT'yi ölçmektedir. NT ölçümünü kimin yapmas› gerekti¤i konusunda fikir birli¤i bulunmamakta-d›r. Bu çal›flmada, ortalama kal›nl›k ve NT'nin da¤›l›m›na ba¤l› olarak üç grupta NT ölçümünün korelasyonunu karfl›laflt›rd›k.Yöntem: Çal›flmaya toplam 929 kat›l›mc› dahil edildi. Yedi radyolog, 8 do¤um uzman› ve 1 perinatoloji uzman› NT'yi ölçtü. Her grup için tepe-makat uzunlu¤u (CRL), ortalama NT ve NT da¤›-l›m› hesapland›.Bulgular: Perinatoloji uzman›n›n ortalama NT ölçümü, radyologla-r›n ve do¤um uzmanlar›n›n ölçümünden anlaml› flekilde daha yüksekti (p<0.05). Ayr›ca perinatoloji uzman› ölçümleri di¤er gruplardan anlaml› flekilde daha farkl› bir da¤›l›ma sahipti (p<0.05). CRL de¤erleri bak›m›ndan gruplar aras›nda hiçbir anlaml› farkl›l›k yoktu. CRL ve NT için %95 güven aral›¤›yla gözlemciler aras› güvenilirlik katsay›lar› s›ras›yla 0.967 (0.910-0.987, p<0.001) ve 0.596 (0.455-0.845, p<0.001) idi.Sonuç: Üç grupta ortalama NT de¤eri ve da¤›l›m› bak›m›ndan istatistiksel olarak anlaml› farkl›l›klar bulunmaktad›r. Perinatoloji uzman› ölçümleri daha yüksek ortalama kal›nl›k ve da¤›l›ma sahiptir. NT ölçümünde bir standart oluflturma ihtiyac› oldu¤u aç›kt›r ve bu üç grubun perinatal sonuçlar› de¤erlendirmesi ve iki grubun en do¤ru sonuç grubuna yaklaflmas› önemlidir.

“…In France, systematic monitoring of pregnancy includes an assessment of NT in the first trimester according to crown‐rump length, which is used for pregnancy dating. Sonographers are accredited on the quality of the first trimester ultrasound using the Herman quality criteria 33,34 . For increased NT below 3.5 mm or the 99th percentile, serum markers for trisomy 21 are first tested.…”

Objectives The antenatal phenotypic spectrum of Noonan Syndrome (NS) requires better characterization. Methods This multicenter retrospective observational included 16 fetuses with molecularly confirmed NS admitted for fetopathological examination between 2009 and 2016. Results Among 12 pathogenic variants (PV) in PTPN11 (80%), 5 (42%) fell between position c.179 and c.182. Ultrasound showed increased nuchal translucency (n = 13/16, 93%), increased nuchal fold after 15 weeks of gestation (n = 12/16, 75%), pleural effusions (n = 11/16, 69%), polyhydramnios (n = 9/16, 56%), hydrops (n = 7/16, 44%), cardiovascular (n = 6/16, 38%) and cerebral (n = 4/16, 25%) anomalies. Fetopathological examination found dysmorphic features in all cases, cardiovascular anomalies (n = 12/15, 80%), pulmonary hypoplasia (n = 10/15, 67%), effusions (n = 7/15, 47%) and neuropathological anomalies (n = 5/15, 33%). Hydrops was significantly (p = 0.02) more frequent in the four fetuses with RIT1, NRAS and RAF1 PV versus the 12 fetuses with PTPN11 PV. Conclusions Increased nuchal translucency and nuchal fold is common in NS. Noonan Syndrome antenatal phenotype showed high in utero fetal death, hydrops, prenatal pleural effusion and pulmonary hypoplasia, although the inclusion of only deceased fetuses will have selected more severe phenotypes. Non‐specific cardiovascular and neurological abnormalities should be added to NS antenatal phenotype. Next generation sequencing will help detect more genotypes, clarifying the prenatal phenotype and identifying genotype‐phenotype correlations.
