RESUMEN

OBJECTIVE: Several studies have compared perioperative parameters and early postoperative morphology between endoscope-assisted strip craniectomy with orthotic therapy (endoscopic repair) and cranial vault remodeling (open repair). To extend these results, the authors evaluated school-age anthropometric outcomes after these techniques across three institutions. METHODS: School-aged children (age range 4-18 years) with previously corrected isolated sagittal craniosynostosis were enrolled. Upon inclusion, 3D photographs and patient-reported outcomes were obtained, and the cephalic index and head circumference z-scores were calculated. Analyses of covariance models controlling for baseline differences and a priori covariates were performed. RESULTS: Eighty-one participants (median [range] age 7 [4-15] years) were included. The mean (95% CI) school-age cephalic index was significantly higher in the endoscopic cohort, though within the normal range for both groups (endoscopic 78% [77%-79%] vs open 76% [74%-77%], p = 0.027). The mean change in the cephalic index from preoperation to school age was significantly greater in the endoscopic group (9% [7%-11%] vs open 3% [1%-5%], p < 0.001). Compared to preoperative measurements, mean school-age head circumference z-scores decreased significantly more in the open cohort (-1.6 [-2.2 to -1.0] vs endoscopic -0.3 [-0.8 to -0.2], p = 0.002). Patient-reported levels of stigma were within the normal limits for both groups. CONCLUSIONS: Endoscopic and open repair techniques effectively normalize school-age anthropometric outcomes. However, endoscopic repair produces a clinically meaningful and significantly greater improvement in the school-age cephalic index, with maintenance of head growth. These findings demonstrate the importance of early referral by pediatricians and inform treatment decisions.

RESUMEN

OBJECTIVE: Trophoblast inclusions-cross sections of abnormal trophoblast bilayer infoldings-have previously been associated with aneuploidy, placenta accreta, and prematurity. This study was conducted to establish the relationship between trophoblast inclusions and a range of placental, pregnancy, and birth outcomes in a patient population with high smoking and alcohol exposure. Specifically, we sought to evaluate the association between the presence of trophoblast inclusions and 1) three primary birth outcomes: full-term birth, preterm birth, and stillbirth; 2) gestational age at delivery; and 3) specific placental pathologies. METHODS: Two slides containing chorionic villi were evaluated from 589 placentas that were collected from Stellenbosch University in Cape Town, South Africa as part of the prospective, multicenter cohort Safe Passage Study of the Prenatal Alcohol and SIDS and Stillbirth Network. The subsample included 307 full-term live births, 212 preterm live births, and 70 stillbirths. RESULTS: We found that the odds of identifying at least one trophoblast inclusion across two slides of chorionic villi was significantly higher for placentas from preterm compared to term liveborn deliveries (OR = 1.74; 95% CI: 1.22, 2.49, p = 0.002), with an even greater odds ratio for placentas from stillborn compared to term liveborn deliveries (OR = 4.95; 95% CI: 2.78, 8.80, p < 0.001). Gestational age at delivery was inversely associated with trophoblast inclusion frequency. Trophoblast inclusions were significantly associated with small for gestational age birthweight, induction of labor, villous edema, placental infarction, and inflammation of the chorionic plate. CONCLUSIONS: The novel associations that we report warrant further investigation in order to understand the complex network of biological mechanisms through which the factors that lead to trophoblast inclusions may influence or reflect the trajectory and health of a pregnancy. Ultimately, this line of research may provide critical insights that could inform both clinical and research applications.

RESUMEN

We sought to examine placentas enriched for trophoblast inclusions (TIs) in order to characterize, quantify, and examine the interrelations between subtypes of TIs to better understand their underlying biology. We examined a cohort of 600 placentas from deliveries between 200 and 430 weeks of gestation. Forty-five percent of the placentas had at least one TI in the two slides examined. Four percent of the placentas had 10 or more TIs and two placentas had more than 70 TIs. Four distinct TI subtypes were observed: inclusionoids (early forming inclusions), inclusions, calcified inclusions, and calcified bodies. We suggest this reflects a developmental trajectory of TI maturation, the timing of which might be useful when comparing TI expression to clinical outcomes.
