Background
The aspect of sexual differentiation and the mechanism controlling the position of genitalia, which represents one of the most substantial differences between the sexes, is still poorly understood. Minor cases and some variants of penoscrotal transposition (PST) are unreported, and obvious cases were classified broadly and confused with other unrelated anomalies.
Methodology
Relevant literature published till 2022 were reviewed then organized, recapitulated, and presented in comparison with the findings and data of 65 child diagnosed with PST. So, an integrated comprehensive approach to this uncommon condition enabled a new classification including few unreported variant cases, which were complemented.
Results
PST is classified herein into a cephalic or caudal scrotal migration, the cephalic type subdivided into major and minor subtypes the latter type subdivided into bilateral, unilateral or central subtypes. Cases of caudal scrotal regression is an unreported anomaly in which the scrotum located caudally, as constant association with epispadias/exstrophy anomalies leaving a wide distance between the fixed penis and the scrotal sacs.
Conclusion
PST is not rare as it was believed, it occurs in two directions; cephalic and caudal directions. Scrotal caudal regression anomaly was not described before, as well the PST presented as an inguinal hernia.

Background
Primary congenital glaucoma (PCG) affects approximately 1 in 10,000 live born infants in the United States (U.S.). PCG has a autosomal recessive inheritance pattern, and variable expressivity and reduced penetrance have been reported. Likely causal variants in the most commonly mutated gene, CYP1B1, are less prevalent in the U.S., suggesting that alternative genes may contribute to the condition. This study utilized exome sequencing to investigate the genetic architecture of PCG in the U.S. and to identify novel genes and variants.
Methods
We studied 37 family trios where infants had PCG and were part of the National Birth Defects Prevention Study (births 1997–2011), a U.S. multicenter study of birth defects. Samples underwent exome sequencing and sequence reads were aligned to the human reference sample (NCBI build 37/hg19). Variant filtration was conducted under de novo and Mendelian inheritance models using GEMINI.
Results
Among candidate variants, CYP1B1 was most represented (five trios, 13.5%). Twelve probands (32%) had potentially pathogenic variants in other genes not previously linked to PCG but important in eye development and/or to underlie Mendelian conditions with potential phenotypic overlap (e.g., CRYBB2, RXRA, GLI2).
Conclusion
Variation in the genes identified in this population-based study may help to further explain the genetics of PCG.

Background
Chromatinopathies are a heterogeneous group of genetic disorders caused by pathogenic variants in genes coding for chromatin state balance proteins. Remarkably, many of these syndromes present unbalanced postnatal growth, both under- and over-, although little has been described in the literature. Fetal growth measurements are common practice in pregnancy management and values within normal ranges indicate proper intrauterine growth progression; on the contrary, abnormalities in intrauterine fetal growth open the discussion of possible pathogenesis affecting growth even in the postnatal period.
Methods
Among the numerous chromatinopathies, we have selected six of the most documented in the literature offering evidence about two fetal overgrowth (Sotos and Weaver syndrome) and four fetal undergrowth syndromes (Bohring Opitz, Cornelia de Lange, Floating-Harbor, and Meier Gorlin syndrome), describing their molecular characteristics, maternal biochemical results and early pregnancy findings, prenatal ultrasound findings, and postnatal characteristics.
Results/Conclusion
To date, the scarce data in the literature on prenatal findings are few and inconclusive, even though these parameters may contribute to a more rapid and accurate diagnosis, calling for a better and more detailed description of pregnancy findings.

Background
Fontaine progeroid syndrome (FPS, OMIM 612289) is a recently identified genetic disorder stemming from pathogenic variants in the SLC25A24 gene, encoding a mitochondrial carrier protein. It encompasses Gorlin–Chaudry–Moss syndrome and Fontaine–Farriaux syndrome, primarily manifesting as craniosynostosis with brachycephaly, distinctive dysmorphic facial features, hypertrichosis, severe prenatal and postnatal growth restriction, limb shortening, and early aging with characteristic skin changes, phalangeal anomalies, and genital malformations.
Cases
All known occurrences of FPS have been postnatally observed until now. Here, we present the first two prenatal cases identified during the second trimester of pregnancy. While affirming the presence of most postnatal abnormalities in prenatal cases, we note the absence of a progeroid appearance in young fetuses. Notably, our reports introduce new phenotypic features like encephalocele and nephromegaly, which were previously unseen postnatally. Moreover, paternal SLC25A24 mosaicism was detected in one case.
Conclusions
We present the initial two fetal instances of FPS, complemented by thorough phenotypic and genetic assessments. Our findings expand the phenotypical spectrum of FPS, unveiling new fetal phenotypic characteristics. Furthermore, one case underscores a potential novel inheritance pattern in this disorder. Lastly, our observations emphasize the efficacy of exome/genome sequencing in both prenatal and postmortem diagnosis of rare polymalformative syndromes with a normal karyotype and array-based comparative genomic hybridization (CGH).

Background
A peculiar subgroup of patients with partial or complete atrioventricular canal defect exhibits a spectrum of left-sided obstructions including right ventricular dominance and aortic coarctation. The association of atrioventricular canal defect with left-sided obstructions is found in several genetic syndromes; however, the molecular basis of nonsyndromic atrioventricular canal defect with aortic coarctation is still poorly understood. Although some candidate genes for nonsyndromic atrioventricular canal defect are known, a complex oligogenic inheritance determined in some cases by the co-occurrence of multiple variants has also been hypothesized.
Case Report
We describe a nonsyndromic infant with mesocardia with viscero-atrial situs solitus, partial atrioventricular canal defect, mild right ventricular dominance, and coarctation of the aorta. Next generation sequencing genetic testing revealed variants in two genes, GDF1 and NOTCH1, previously reported in association with atrioventricular canal defect and left-sided obstructive lesions, respectively.
Conclusion
The present report could support the hypothesis that the co-occurrence of cumulative variants may be considered as genetic predisposing risk factor for specific congenital heart defects.

Background
Autism spectrum disorder (ASD) is the fastest-growing child neuropsychiatric condition. Cognitive dysfunctions such as memory impairments are experienced by patients along with social disturbances and repetitive/stereotypic movements. We have used the radial arm maze (RAM), for measurement of working and reference memory errors in an animal model of autism. In addition, the potential effects of agmatine, an endogenous NMDA antagonist, on RAM performance and autistic-like behaviors were assessed.
Methods
Autism was modeled by valproic acid (VPA) administration at gestational Day 12.5. Autism-associated behaviors in male offspring were examined in an open field test (OFT) and three-chambered test (TCT) on postnatal days 50–51. Thereafter, the animals were trained in the RAM (PND 55) until they attained the criteria of 80% correct choices during five consecutive trials. Forty-eight hours after the acquisition of criteria, agmatine was injected 30 min before subsequent behavioral testing, which included the retention phase of the RAM, OFT, and TCT.
Results
VPA-treated and intact rats showed the same performance in RAM, and acute injection of agmatine rescued social and anxiety-like behavior induced by VPA without the effect on RAM.
Conclusion
In a rat model of autism, spatial learning, and memory did not change. Agmatine rescued social and anxiety-like behavior in autistic animals.

Background
Gastroschisis is a congenital anomaly of the umbilical ring with increasing prevalence, especially amongst younger mothers. There is increasing evidence that exposure to genitourinary infections (GUTI) may play an important role in the etiology of gastroschisis. This systematic review and meta-analysis aimed to identify, appraise, and summarize the literature on exposure to GUTI and gastroschisis.
Methods
Six electronic databases (MEDLINE, EMBASE, Web of Science, Scopus, Cochrane Library electronic databases, and Prospero) were searched using a comprehensive search strategy. Citations and cited articles for all included studies were searched. Peer-reviewed, quantitative studies reporting an association of urinary tract infections (UTI) and/or sexually transmitted infections (STI) with gastroschisis were included. Prospero registration CRD42022377420.
Results
A total of 2392 papers were identified via the searches of which 15 met our inclusion criteria and were included after title and abstract and full text screening. The study period for included studies ranged from 1995 to 2016, most were from the USA. Four studies considering exposure to STIs and five to UTIs were eligible to progress to meta-analysis. Meta-analysis identified a significantly increased risk of gastroschisis in association with periconceptional exposure to UTI [OR 1.54 (95% CI 1.29, 1.8)], STI [OR 1.4 (95% CI 1.01, 1.79)].
Conclusions
Periconceptional exposure to GUTI is associated with an increased risk of gastroschisis. The prevention and timely treatment of GUTI amongst women of childbearing age may help to reduce the occurrence of gastroschisis.

On May 29, 2023, the 76th World Health Assembly (WHA) unanimously adopted the resolution entitled, “Accelerating efforts for preventing micronutrient deficiencies and their consequences, including spina bifida and other neural tube defects, through safe and effective food fortification.” The Society for Birth Defects Research and Prevention published their resolution in 2015 supporting mandatory fortification of staple foods with folic acid and recommendations aiming to achieve global total prevention of folate-sensitive spina bifida and anencephaly, setting a goal to achieve by the year 2024. The WHA resolution provides another global push for the cause, with recommendations to member nations for food fortification to be achieved by the year 2030.
Methods
This short communication documents the steps, from inception up to the passage, of the 76th WHA resolution on food fortification, with a narrative on the nature of strategic advocacy efforts by multiple governmental and nongovernmental organizations.
Results
WHA resolutions can take many years to be introduced and passed by the assembly; however, this is a case study of the swiftness of the process enabled by powerful global partnership.
Conclusion
The documentation of this process serves as an example for developing and processing future WHA resolutions aiming to improve global maternal and child health.

Background
This study investigates how congenital heart diseases (CHD) characteristics and interventions affect cognitive and verbal skills in Arab children, while also uncovering previously unexplored connections between these skills and the quality of life (QoL) scores as perceived by both children and parents.
Methods
A cross-sectional study was conducted in Jordan, involving 62 children with CHD aged 6–16. Data were collected through standardized intelligence tests (namely The Raven's Progressive Matrices Test and The Wechsler Intelligence Scale for Children) and QoL assessments.
Results
Sex, disease severity, cyanosis, CHD defect status, conducted operations, and types of interventions did not significantly influence cognitive scores. However, a significant difference was observed in Wechsler's scores between cyanotic and non-cyanotic children (p < .01) and between severe and moderate cases (p = .01). Further, a significant positive correlation was identified between Wechsler's Scores and QoL reported by parents (r = 0.33, p < .01). This correlation was particularly pronounced in the social and school functioning dimensions of QoL.
Conclusions
This study highlights the need for personalized care approaches for children with CHDs based on their individual characteristics. While cognitive abilities did not directly correlate with children's QoL reports, a significant positive correlation between verbal skills and QoL reported by parents underscores the importance of effective communication in assessing a child's overall well-being. Future research should further examine the cognitive development in this population, employing neurocognitive investigations and longitudinal studies to gain a deeper understanding of their cognitive profiles and trajectories.
背景：本研究探讨了先天性心脏病（CHD）的特点和干预措施如何影响阿拉伯儿童的认知和语言能力，同时还揭示了这些能力与儿童和家长认为的生活质量（QoL）得分之间以前未曾探讨过的联系：在约旦进行了一项横断面研究，涉及 62 名 6-16 岁患有先天性心脏病的儿童。数据通过标准化智力测验（即瑞文渐进矩阵测验和韦氏儿童智力量表）和 QoL 评估收集：结果：性别、疾病严重程度、发绀、先天性心脏病缺陷状况、进行过的手术和干预类型对认知评分没有显著影响。然而，发绀儿童与非发绀儿童的韦氏评分存在明显差异（p 结论：该研究强调了个性化治疗的必要性：本研究强调了根据患有先天性心脏病的儿童的个体特征采取个性化护理方法的必要性。虽然认知能力与儿童的 QoL 报告没有直接相关性，但言语能力与家长报告的 QoL 之间存在显著的正相关性，这强调了有效沟通在评估儿童整体福祉中的重要性。未来的研究应通过神经认知调查和纵向研究来进一步考察这一人群的认知发展，从而更深入地了解他们的认知概况和发展轨迹。

Background
Associations between maternal periconceptional exposure to disinfection by-products (DBPs) in drinking water and neural tube defects (NTDs) in offspring are inconclusive, limited in part by exposure misclassification.
Methods
Maternal interview reports of drinking water sources and consumption from the National Birth Defects Prevention Study were linked with DBP concentrations in public water system monitoring data for case children with an NTD and control children delivered during 2000–2005. DBPs analyzed were total trihalomethanes, the five most common haloacetic acids combined, and individual species. Associations were estimated for all NTDs combined and selected subtypes (spina bifida, anencephaly) with maternal periconceptional exposure to DBPs in public water systems and with average daily periconceptional ingestion of DBPs accounting for individual-level consumption and filtration information. Mixed effects logistic regression models with maternal race/ethnicity and educational attainment at delivery as fixed effects and study site as a random intercept were applied.
Results
Overall, 111 case and 649 control children were eligible for analyses. Adjusted odds ratios for maternal exposure to DBPs in public water systems ranged from 0.8–1.5 for all NTDs combined, 0.6–2.0 for spina bifida, and 0.7–1.9 for anencephaly; respective ranges for average daily maternal ingestion of DBPs were 0.7–1.1, 0.5–1.5, and 0.6–1.8. Several positive estimates (≥1.2) were observed, but all confidence intervals included the null.
Conclusions
Using community- and individual-level data from a large, US, population-based, case–control study, we observed statistically nonsignificant associations between maternal periconceptional exposure to total and individual DBP species in drinking water and NTDs and subtypes.
