Individual growth patterns in the first trimester: evidence for difference in embryonic and fetal growth rates. (1/203)

OBJECTIVE: To evaluate individual fetal growth during the first trimester in pregnancies resulting from spontaneous and in vitro fertilization (IVF). METHODS: The growth of 11 fetuses conceived by spontaneous fertilization (known dates of ovulation) in nine patients and 15 fetuses conceived by IVF in 12 patients were evaluated at weekly intervals from 6 weeks, menstrual age, to 14 weeks. Fetal length was determined at each examination. Measures of fetal length included the crown-rump length (CRL), maximum straight line length (MSLL) and maximum axial length (MAL). Comparisons of CRL and MSLL to MAL were carried out. The MSLL was used as the measure of length except when the MAL was available. Linear and quadratic functions were fitted to the complete data sets of individual fetuses in the two groups. Individual data sets from ten fetuses in each group were then divided into early and late growth phases, and linear functions were fitted to each data subset. Start points and pivotal points for each fetus were estimated from the coefficients of these two functions. Growth in these two groups of fetuses was compared, on the basis of slope values. RESULTS: Evaluation of length measures indicated that, before 8 weeks, only MSLL could be measured. After 8 weeks, all three measures could be obtained, with the MAL being the largest. Both the linear and quadratic models performed well with individual data sets (mean R2(+/- SD): linear 98.1 (1.0)%; quadratic 99.4 (0.4)%), with no differences found between spontaneous and IVF groups (maximum possible differences in mean slopes (95% probability): 5-8%). Similar findings were obtained for the early and late growth phase data subsets. Slope values in the early and late growth phases showed low variability (CV: early 13.5%; late 11.6%), but were significantly different (early 0.72 (+/- 0.10 SD) cm/week; late 1.21 (+/- 0.14 SD) cm/week). The mean start point was 5.9 (+/- 0.3 SD) weeks' menstrual age, while the mean pivotal point was 9.2 (+/- 0.7 SD) weeks, menstrual age. CONCLUSIONS: First-trimester growth studies in individual fetuses indicate that there is a change in length growth rate between 9 and 10 weeks, menstrual age. This is consistent with a shift in development from organogenesis to growth. These results can be used for more accurate assessment of first-trimester growth and may aid in the detection of fetal problems that manifest themselves as growth abnormalities.  (+info)

The 'Mickey Mouse' sign and the diagnosis of anencephaly in early pregnancy. (2/203)

OBJECTIVES: To assess the sonographic screening for anencephaly in the first trimester in a low-risk obstetric population. METHODS: Since 1994, 5388 women attended our clinic for a first-trimester scan (11-14 weeks of gestation) and screening for structural and chromosomal abnormalities. The patients underwent transabdominal scanning, and transvaginal scanning if necessary. RESULTS: The ultrasonographic appearances of anencephaly in the first trimester are different from the familiar second-trimester signs. The cerebral hemispheres are present and exposed to the surrounding amniotic fluid. The ultrasound appearances in the coronal section of the head are best described as 'Mickey Mouse face'. There were six cases of anencephaly (incidence 1.1:1000). All cases were diagnosed in the first trimester and five demonstrated this sign. There were no false-positive diagnoses. The crown-rump length was significantly reduced in all affected fetuses. CONCLUSION: First-trimester ultrasonographic diagnosis of anencephaly is accurate, but sonographers should be familiar with the ultrasound appearances that are different from those in the second trimester.  (+info)

Biometrical threshold of biparietal diameter for certain fetal sex assignment by ultrasound. (3/203)

OBJECTIVES: The aim of this study was to establish the biometric threshold of biparietal diameter (BPD), assumed to be an independent variable of gestational age, at which 100% accuracy in the assessment of fetal sex by ultrasonography is achievable. METHODS: Transvaginal and/or transabdominal sonography was used for detecting the 'sagittal sign' as a marker of fetal sex in 385 fetuses with BPD between 18 and 29 mm. The results of ultrasound examination were compared with sex at birth or with karyotype obtained from amniotic fluid cells or chorionic villus sampling. RESULTS: Fetal sex assignment was feasible in 337 of 385 cases (87.5%). Of the 312 fetuses with known fetal sex outcome, 164 were males and 148 were females. An accuracy rate of 100% was achieved when a BPD of > or = 23 mm was obtained. CONCLUSION: This study provides important information about the earliest stage of fetal development, expressed in terms of BPD, at which a diagnosis of fetal sex can be made with 100% accuracy.  (+info)

Maternal cigarette smoking during pregnancy and infant ponderal index at birth in the Swedish Medical Birth Register, 1991-1992. (4/203)

OBJECTIVES: This study examined the effect of maternal smoking during pregnancy on infant body proportion. METHODS: The ponderal index, defined as birthweight divided by crown-heel length cubed, was examined in 207,607 infants from the Swedish Medical Birth Register for 1991 and 1992. RESULTS: Infant ponderal index was used as the outcome variable in an ordinary least squares continuous regression, which included early pregnancy smoking status, gestational age, and birthweight among the predictors. Ponderal index increased by 0.030 (+/- 0.0014) among infants of moderate smokers and by 0.040 (+/- 0.0017) among infants of heavy smokers, showing a dose response. CONCLUSIONS: Smoking differentially alters the trajectory of weight vs length growth in the fetus.  (+info)

Relationship between fetal femur diaphysis length and neonatal crown-heel length: the effect of race. (5/203)

OBJECTIVE: To determine whether racial differences affect the relationship between the fetal femur diaphysis length and the neonatal crown-heel length. DESIGN: A prospective study in a teaching hospital with a multiracial population. SUBJECTS: Four hundred and fifty pregnant women (150 Malays, 150 Chinese and 150 Indians) who delivered live infants. METHODS: Ultrasound scan measurement of the fetal femur diaphysis length was carried out within 48 h of delivery in all cases. The relationship between the neonatal crown-heel length and the femur diaphysis length was obtained by regression using the method of least squares. Dummy or indicator variables were used to determine the effect of race on the relationship. RESULTS: The relationship between the neonatal crown-heel length and the femur diaphysis length in all three races was well described by a linear model but a quadratic model described the relationship better. There was no significant difference in relationship of the neonatal crown-heel length and the femur diaphysis length between the Malay and Chinese populations, but the relationship in the Indian population was significantly different was from both the Chinese and Malay. For a given femur diaphysis length, the crown-heel length of the Indian population was found on average to be 1.1 cm shorter than the crown-heel length of the Malay and Chinese populations. CONCLUSION: Differences in fetal body proportions exist between some races. The longer femur diaphysis length noted in certain races does not necessarily imply that the corresponding crown-heel length is longer. These inter-racial differences may increase the error of fetal weight and length estimates if formulae, which have been derived from samples racially dissimilar to that of the target population are used.  (+info)

Gestational age in pregnancies conceived after in vitro fertilization: a comparison between age assessed from oocyte retrieval, crown-rump length and biparietal diameter. (6/203)

OBJECTIVE: To compare gestational age (GA) and day of delivery estimated from the time of in vitro fertilization (IVF) (oocyte retrieval + 14 days), the ultrasonic measurement of the crown-rump length (CRL) and the biparietal diameter (BPD) in pregnancies conceived in an IVF setting. DESIGN: Included were 208 singletons and 72 twin pregnancies conceived after IVF. GA estimated from the time of IVF was compared with the GA estimated from the ultrasonic measurement of the CRL in the first trimester and the BPD in the second trimester. RESULTS: In singletons the mean difference in gestational age was 0.9 days between IVF and CRL estimates and 2.1 days between IVF and BPD estimates. The gestational age as estimated from CRL or BPD was shorter than the GA estimated from IVF. There was no systematic variation in the mean differences in GA between the methods. In three pregnancies there was a difference of more than 7 days between the gestational age estimated from IVF and CRL and in 22 pregnancies between gestational age estimated from IVF and BPD. A difference of > 14 days for any of the estimates was not found in any case. In singletons there was a high correlation in the gestational age at birth assessed from the time of IVF and from CRL, from the time of IVF and from BPD. CONCLUSION: Assessment of gestational age from the time of IVF, CRL and BPD in pregnancies conceived after IVF shows equally high agreement between the three methods. This supports the use of ultrasound as a reliable method for estimation of gestational age.  (+info)

Alobar holoprosencephaly at 9 weeks gestational age visualized by two- and three-dimensional ultrasound. (7/203)

We present the ultrasound detection of alobar holoprosencephaly (HPE) with cyclopia in an embryo of 9 weeks 2 days last menstrual period (LMP)-based gestational age; the crown-rump length (CRL) was 22 mm. The use of three-dimensional (3-D) ultrasound made additional diagnostic ultrasound tomograms possible, and the volume reconstructions improved the imaging and the understanding of the condition.  (+info)

The prenatal cranial base complex and hand in Turner syndrome. (8/203)

From early childhood, Turner syndrome patients have a flattened cranial base, maxillary retrognathism, and short hands. There are, however, no studies that show when these genotype-determined abnormalities occur prenatally. The purpose of the present study was to measure craniofacial profile and hand radiographs of second trimester foetuses with Turner syndrome and compare the results with similar measurements from normal foetuses. The subjects consisted of 12 Turner syndrome foetuses, gestational age (GA) varying between 15 and 24 weeks, and crown-rump length (CRL) between 108 and 220 mm. The mid-sagittal block of each cranium was analysed as part of the requested brain analysis (pituitary gland analysis). This block and the right hand from seven foetuses were radiographed, and the skeletal maturity of the cranial base complex, i.e. the cranial base and the maxilla, was evaluated from the profile radiographs. Shape and size measurements in the cranial base were performed, and compared with normal values according to cranial maturity and to CRL. The cranial base angle in Turner syndrome was greater and the maxillary prognathism was reduced compared with the normal group. The dimensions in the cranial complex and in the hand showed that the bone lengths and distances in relation to CRL were generally smaller compared with normal foetuses. This investigation showed that the abnormal shape of the cranial base complex and the short hands in Turner syndrome are present prenatally.  (+info)

Results: Twenty days after positive smear testing, only n=3 of 5 mated offspring from hypoxic pregnancies were carrying pregnancies. Our preliminary data showed that litter size was higher in pregnant control offspring (median 16, range 15-17) than pregnant offspring prenatally exposed to maternal hypoxia (median 13, range 5-16). Fetal crown-rump lengths from hypoxic pregnancy offspring (mean 3.8 ± 0.2 cm) tended to be smaller than those of control offspring (4.0 ± 0.2 cm; p=0.07). Endothelial-dependent relaxation was greater in uterine arteries from pregnant compared to non-pregnant dams ( ...
I dont know who else to confide in so Im posting here. Today my husband and I went in for my 12w NT ultrasound test. We got devastating news- that our NT measurement was 6.0mm (worried about Down Syndrome and other chromosomal defects above 3.0). They DID see two prominent nose bones and baby had a gray heart rate (155bpm). We know there a lot of steps before we jump to conclusions, including a detailed genetic blood workup (which we did today) but also being referred to a high risk OB. I am already devastated and have been crying all day at the thought of having a baby that isnt viable. Has ANYone had thoughts or experiences with a high NT measurement but normal results? Any thoughts would be so appreciative.

Cortical cells from embryonic Sprague Dawley rat pups at E18 and E19 were analyzed because on these days we found peak levels of GABA-induced migration (Behar et al., 1996). Embryonic age was determined by the appearance of a vaginal plug (day 1) and measurement of crown-rump length (Schaffner et al., 1993). Dams were euthanized with CO2, and embryos were removed by cesarean section. Brains from littermates were removed and placed into cold (4°C) Leibovitzs L-15 medium (Life Technologies, Grand Island, NY) supplemented with 0.1 mg/ml bovine serum albumin (BSA; Sigma, St. Louis, MO) and 16 mmglucose. A McIlwaine tissue chopper (Brinkman, Westbury, NY) was used to prepare 350 μm coronal slices of the telencephalon. Slices were transferred to a dish containing the L-15 medium, and the slices were teased apart and cleaned of meninges under a dissecting microscope. Individual slices were transferred to a clean 35 mm dish and covered with a drop of the L-15 medium. The ...

Fetal intra-uterine growth charts are generally based on last menstrual period (LMP) data. Such charts may not really be applicable to infants whose gestational age is ultrasonically determined in early pregnancy. 1369 consecutive singleton pregnancies were studied. All fetuses had their gestational age estimated both by ultrasonic measurement of fetal crown-rump length and from registered last menstrual period data. All infants were weighed at birth as a part of the routine care. The age determination according to the two methods differed in 664 out of 1369 cases and in 516 of these 664 cases the age according to LMP was higher than according to CRL - a highly significant difference (p , 0.001). Mean values for birth weight were found to be larger when correlated to age in terms of CRL determinations than when related to age as calculated from LMP data. Birth weight also showed a significant increase between 40 and 42 weeks when age was determined ultrasonically. This was not the case when age ...
The Fetal Medicine Foundation is a Registered Charity that aims to improve the health of pregnant women and their babies through research and training in fetal medicine.
Objectives: To assess the impact of ultrasound (US) in resource poor settings, we tested the hypothesis that US estimates of gestational age (USGA) would result in a different preterm birth (PTB: |37 weeks) rate to that derived from clinical estimates based upon menstrual dates and/ or fundal height measurements (CGA) in a rural Kenyan population at high risk of adverse birth outcomes (estimated perinatal mortality = 80-120/1000). Methods: PTB rates according are calculated using USGA and CGA estimates measured for all women attending Kilifi District Hospital for antenatal care at |24 weeks (CGA). Clinical information including the date of the last menstrual period is recorded by government staff as part of routine care. Locally trained sonographers measure fetal crown-rump length (|14 weeks) or head circumference in the trans-thalamic plane (|14 but |24 weeks): USGA is calculated from the mean of 3-blinded measurements using published formulae. Outcomes are determined using the largest demographic
OBJECTIVE: Studies have suggested that fetuses with holoprosencephaly have smaller head size, demonstrated as early as the first trimester. However, the majority of these cases were diagnosed in the second or third trimesters. The aim of this study was to investigate biparietal diameter (BPD) measured at 11 to 13 weeks gestation in fetuses with holoprosencephaly. METHODS: This was a retrospective study in which BPD was measured at 11 to 13 weeks in 34 fetuses with prenatal diagnosis of holoprosencephaly and 7775 unaffected controls. BPD values were converted into multiples of the expected median (MoM) after adjustment for crown-rump length and maternal characteristics. RESULTS: The median gestational age at the BPD recording was 12.6 (interquartile range 12.3-13.0) weeks. The nuchal translucency was increased (≥3mm) in 58.8% of the cases. Aneuploidy was confirmed in 73.5% of the cases; the commonest was trisomy 13 (50.0%). BPD values at 11 to 13 weeks were below the 5(th) centile in 32.4% of cases

ZM is a plant used to remedy dyspepsias in pregnant women. EA is a plant used as a stomach and heart tonic, carminative and in remedy of skeletal and muscular ailments. In order to investigate the probable effects of this extracts on the fetus digestive system the current study was examind. Twenty-eight pregnant balb/c mice (25-30 gr) were divided into control, sham and expremental groups (n=7). From 6th to 15th gestation days, food and water of mouses were removed for about 3 hours. The expremental groups were gavaged with 200 mg/kg/day and 640 mg/kg/day aqueous extracts of ZM and EA in 0.5 ml distilled water, respectivly. The sham group was gavaged with equal amount of distilled water. Pregnant mice were dissected in 16th day of pregnancy. Crown-Rump length (CRL) and weight of them were measured. Seven fetuses from different mothers were selected. Five µm transverse serial sections with 75 µm interval were prepared. The Cavalieri method was applied to estimate the volume of different parts of
The fetal pole is a thickening on the margin of the yolk sac of a fetus during pregnancy.

Animals. The generation of the NGF and Trk null mutant mice used in this study has been described (NGF,Crowley et al., 1994; trkA, Smeyne et al., 1994;trkC, Klein et al., 1994). NT-3(−/−) mice (Ernfors et al., 1994) were obtained from Jackson Laboratory (Bar Harbor, ME). Wild-type (WT), and (−/−) mutants were obtained from the overnight matings [day of vaginal plug = embryonic day 0.5 (E0.5)]. Pregnant females were killed by halothane overdose to harvest embryos on E11.5, E13.5, or E15.5. Staging of embryos was verified by crown-rump length and degree of limb development. The genotyping of mice was performed by polymerase chain replication using primers published in the studies cited above. Embryos were frozen immediately on dry ice and stored at −80°C until use.. Outbred CF-1 (Charles River Labs, Wilmington, MA) mouse embryos were used to supplement the in situ hybridization and immunocytochemistry analyses because of the greater availability of these animals.

Something unusual is clearly going on with cytokines and ME/CFS - something Mark Davis hadnt seen before. He suggested that the healthier patients might be able to tamp down a pro-inflammatory process that the sicker patients cant rein in at all - leaving them exposed to the full force of the pro-inflammatory cytokines. Exhibiting his wry sense of humor, Davis opined that that idea "could be true, might be true and ended up with calling it a definite maybe".. Davis saved the best for last. Mark Davis has developed a method to track T-cell clonal expansion in various diseases. T cells "go clonal"; i.e. start producing replicas of themselves in vast numbers when they meet up with an antigen - a protein nipped off a pathogen or toxin by an immune presenting cell - they dont like. The T-cells produced during this process are like a honing missile; theyre designed for one purpose and one purpose only - to search out and destroy anything that presents with that antigenic signature. High numbers ...

Answers from experts on how do they measure nuchal translucency. First: Nuchal translucency (nt) is typically measured between weeks 11 and 14. The sonographer measures the thickness of the tissues of the back of the fetal neck. After the image is magnified, calipers are placed along the inner margin of the tissues of the neck.
In cats, accuracy of parturition day prediction by ultrasonographic measurement of foetal structures is decreasing towards the end of gestation. Foetal measurements during the last days of pregnancy are scarce. We determined foetal biparietal, abdominal and eye diameter (BPD, AD and ED, respectively) by ultrasonography as well as maternal blood progesterone (P4) within five days of delivery to predict parturition date and calculate accuracy of prediction. Foetal BPD at birth was compared with newborn kitten head diameter (HD). Kitten HD, crown-rump length (CRL) and body weight were compared by breed and gender. Ultrasonography measurements were carried out on the day of parturition in 14 queens, and on days 62-63 after the first mating and repeated 24-72 hr later in ten other cats. Accuracy of parturition day prediction using BPD and AD was determined based on the equations of Beccaglia et al. (2008) Veterinary Research Communications, 32(Suppl 1), S99 and Garcia Mitacek et al. (2015) ...

AFM, after we got signed off by the clinic at 7wks2days after our u/s, we went to our local doctor last week to let them know that Im pregnant. Apparently all of my care is going to be midwife based and I wont have much to do with the doctor, so were now waiting for the midwife to get in touch to make a first appointment to see us so that we can find out a bit more about this whole process. I was expecting to be put into the hospital system and get given a date for a 12 week scan, but the doctor said that since weve already had a dating scan at 7 weeks at the clinic, that I wont be offered a 12 week scan on the NHS and will next be seen at 20 week. What????? So I think weve decided that were going to pay to have a 12 week scan done privately (and for a nuchal scan at the same time to do a Downs Syndrome assessment). It seems way too long to go for 13 weeks without a scan (even if this were a normal pregnancy, let alone one that Ive waited 4 years for and done countless fertility ...

He did explain that it used to be thought of as an indicator for Downs Syndrome, but this is no longer the case, praise God.

There were 37 078 normal pregnancies and 264 with trisomy 21, 81 with trisomy 18, 38 with trisomy 13 and 27 with Turner syndrome. We found that firstly, contrary to the assumption underlying the delta NT method, the distribution of delta NT changes with CRL and secondly, contrary to the assumption underlying the MoM method the distribution of NT was not Gaussian. Fetal NT followed two distributions, one that was dependent on CRL and one that was independent of CRL. The distribution in which NT increases with CRL was observed in about 95% of euploid fetuses, 5% with trisomy 21, 30% with trisomy 18, 15% with trisomy 13 and 10% with Turner syndrome. The median CRL-independent NT was 2.0 mm for the euploid group and 3.4, 5.5, 4.0 and 7.8 mm for trisomies 21, 18, 13 and Turner syndrome, respectively. ...
September 6, 2016 -- In a disturbing new finding, first-trimester ultrasound was linked to greater severity of autism symptoms, including poorer cognitive outcomes and increased repetitive behaviors, in fetuses with a genetic predisposition to autism spectrum disorder (ASD), according to research published online September 1 in Autism Research.. In a retrospective analysis of data from a national autism genetic repository, a team led by Sara Jane Webb, PhD, of the Seattle Childrens Research Institute found that first-trimester ultrasound was associated with lower mean nonverbal IQ and increased repetitive behaviors in boys with ASD and gene copy number variations (CNVs), compared with those who hadnt undergone a first-trimester ultrasound study.. In addition, having a first-trimester ultrasound correlated with increased repetitive behaviors for all children with ASD in the study, regardless of gender or the presence of identified CNVs.. "These data suggest that heterogeneity in ASD symptoms ...

Betamethasone is proven to be better than dexamethasone in reducing the neonatal morbidity and mortality, and cause less incidence of chorioamnionitis(1,2). However, as the betamethasone salt available in India is different from that used in international trials (3), same conclusion cannot be drawn, and either dexamethasone or betamethasone may be used depending upon availability.. There is also concern over increased prevalence of undiagnosed maternal infections in India, hence, more trials are needed on safety of use of corticosteroids. One of the trials showed increase in neonatal mortality and maternal infection with use of ACS in low-income and middle-income countries (4).. Use of ACS in late preterm babies (34 - 37 weeks) and early term (37 - 39 weeks) has been a matter of controversy so far and more data are needed to either support or refute the use of ACS in these populations. There are definite short-term benefits (mainly in reducing transient tachypnea of newborn) with some ...

Kutsche and Van Mierop4 described CORSA in 1984. They found this anomaly in 4 of 21 infants (19%) studied for aortic arch interruption. The origin of the vessel was seen along with the origins of the internal and external carotid arteries as a trifurcation, at the level of the thyroid gland. It then descended down the neck to enter the right arm. The right recurrent laryngeal nerve was seen to course around the origin of the right subclavian artery, much higher than normal. The pathogenesis of CORSA can be explained by impairment of fourth aortic arch development, before the involution of the right ductus caroticus (segment of the dorsal aorta between the third and fourth arches).

Looking at Felixs mohawk today reminded me of the day he was born. The Doctors were pretty sure he was going to be born with Down Syndrome because he had an absent nasal bone on my 19 week ultrasound, but we had refused an amniocentisis to confirm his diagnosis. Even if he had Down Syndrome, it didnt change how we felt about him; it probably made us fall in love with him a little deeper. Anyway, the second he was born, I wanted to look at his little face to see if he did, in fact, have Down Syndrome. It was obvious by his beautiful eyes and little flat face that he did. He was perfect. Nathans first comment after seeing his son for the first time?? "Awesome, he has a mohawk!" There was no mention of his Down Syndrome being confirmed; just a very proud Daddy SO excited that his baby son was born with a mohawk. Did I ever tell you that my husband is amazing ...

Proximal femoral focal deficiency, PFFD, is a congenital anomaly of the pelvis and proximal femur which causes hip deformity and shortening and altered function of the involved lower extremity. The condition may be unilateral or bilateral and is often associated with other congenital anomalies. Embryology: The developing human embryo first shows evidence of limb buds at the 5 millimeter crown-rump stage.As the apical mesoderm proliferates the limb is laid down in a proximo-distal fashion to be complete at the 12 millimeter stage. Elements of the ileum and proximal femur develop from a common cartilaginous anlage, with subsequent cleft formation to create a joint cavity. This means that if an acetabulum is seen in radiograph at any time in the first year of life a femoral head and neck will be present also, even if not evident in the radiograph. Etiology: Numerous agents including irradiation, anoxia, ischemia, mechanical or thermal injury, bacterial toxins, viral infection, chemicals and ...

Read ratings and reviews for Dr. David Mclean who has 32 years of experience as a Maternal & Fetal Medicine Doctor in Madera, CA.
Its always a relief to go to the hospital and hear that everything looks good. Today I had a lengthy ultrasound for a nuchal translucency test. I guess thats to make sure the spinal cord is developing properly. According to the doctor, it looks fine. I got to watch the baby for a while, but it was pretty still and quiet. So, the doctor told me to cough and then she poked it a bit, and then it woke up and started squirming around. It was probably a little angry at being disturbed, but I got a kick out of seeing it move around. It measures 6.7 cm, which is surprising, because I cant see anything when I look at my stomach, and I weigh the same as when I went in last time a month ago. I thought for sure all that pizza and ice cream was adding up, but I guess not ...
It has been, and still is, a very emotional thing to go through. Ill never forget the day the doctors told us our baby had a problem. We went into our 14 week Nuchal Translucency scan, it was a "just in case" sort of thing and really I just wanted another excuse to see our baby again. After about 40 minutes of scanning and happily watching our baby move around the sonographer told us there was a defect. We had never heard of gastroschisis and after a lot of tears together, and with our family, we set about researching every single possible piece of information that was available. I googled, you tubed, read about, dreamed about, obsessed about, finding out what our baby would be facing ...
The scan went well- NT measurement was counted as 2.2 (that was the highest of several measurements she took, but I guess they count the highest one). The tech and my OB were very happy with this, especially given that I was measuring a couple days ahead at 13wks0days (they said that the normal measurement depends a bit on how far along you are- in this case, the OB said up to 2.8 would have been fine). They did see the nasal bone and there were all 4 limbs so that was good! Although, there was a moment at the beginning of the scan where I started internally freaking out b/c I saw 2 arms, but no legs! It turned out it was just how the baby and the probe were positioned, and I breathed a sigh of relief when 2 little legs and feet came into view. Funny the things you can freak out about! The baby was making little motions with its shoulders like Bill Cosby did in the Jello commercials (I dont know if anyone knows what Im talking about...) but my husband asked if it was normal for the baby to ...
We waited in the waiting room for two hours. My husband and I couldnt even look at each other, we were so terrified. The doctor scurried by and said "they have to record the measurements and do the calculations, then well get back to you". She went off to do some IUIs and IVFs. Eventually, no one else was left in the clinic waiting room but us. Normally there are 30 - 50 people sitting around. I felt like we were such a sad and rejected couple, sitting there waiting and no one wanted to talk to us. My stomach was in a knot. Finally, she came back and sat us down in her office. I hoped for some good news. "Unfortuantely, the scan was abnormal today. Im so sorry. I know this isnt the news you want to hear", she said. We were stunned. What did this mean? She said we had 1:2 chance of chromosomal abnormalities with the NT reading that we got, combined with my age. A normal NT thickness is under 3mm and our babys was 4.7mm. She said the chances are very high for Trisomy 21, 13, or 18, or ...

thanks Teresa, am really happy, will try post them at work tomorrow. you are going to be so amazed when you go for your twelve week scan, honestly its fab, even at ten weeks you could see everything, little nose and legs and arms moving around, the only slight niggle was she said my cervix was short, so they would keep an eye on it and might stitch it up if they have any concern, am not worried though will just wait for ,my next scan. take care hunni. x ...
OBJECTIVES: To evaluate the performance of first-trimester screening for trisomy 21 by a combination of maternal age, fetal nuchal translucency (NT) and maternal serum free beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A). In addition, the potential impact of a new individual risk-orientated two-stage approach to first-trimester screening was ...
Maternal Fetal Medicine is a sub-specialty of obstetrics that focuses on the diagnosis and treatment of expectant mothers and their unborn babies. Maternal Fetal Medicine physicians specialize in providing care for women who are at high risk for problems during their pregnancies, but you may benefit from seeing one of these specialists even if you are experiencing a healthy pregnancy. We perform Non Stress Tests, Biophysical Profiles, Level 2 Ultrasounds, Nuchal Translucency Testing and Amniocentesis.
What is a maternal fetal medicine (MFM) specialist?. Maternal fetal medicine specialists are doctors who are specially trained to care for women with high-risk pregnancies. Mothers with diseases such as hypertension or diabetes, babies with possible genetic conditions or mothers expecting multiple babies can all benefit from the care of a maternal fetal medicine specialist. These doctors receive two to three years of additional training that focuses on high-risk pregnancies, ultrasound techniques and fetal anomalies.. Why would an expectant mother wish to be referred to a maternal fetal medicine specialist?. Most women seek consultation from or care by a maternal fetal medicine specialist because they are "at risk" and considering becoming pregnant or because they are pregnant and "high-risk," "complicated" or otherwise worried about their pregnancy.. What types of patients are seen by maternal fetal medicine specialists?. Patients undergoing diagnostic or therapeutic procedures during ...
Objective To establish an algorithm for first-trimester combined screening for trisomy 21 with biochemical testing from 7 to 14 weeks gestation and ultrasound testing at 11-13 weeks. Methods This was a multicenter study of 886 pregnancies with trisomy 21 and 222 475 unaffected pregnancies with measurements of free beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) at 7-14 weeks gestation. Multiple regression modeling of log-transformed marker values was used to produce log multiples of the median (MoM) values for PAPP-A and free beta-hCG. The models included terms for the center attended and the machine used for biochemical analysis, gestational age, maternal racial origin, maternal weight, smoking status and method of conception. Bivariate Gaussian distributions were fitted to log MoM PAPP-A and log MoM free beta-hCG in trisomy 21 and in unaffected pregnancies. In each case the patient-specific risk for trisomy 21 was estimated by multiplying the ...
