Enteric duplication cysts in paediatric population along with literature review / Quistes de duplicación entérica en población pediátrica y revisión de la literatura

The clinical presentation of enteric duplication cysts is dependent on the location of the cyst with symptoms varying from nausea and vomiting to abdominal distension, pain and perforation. Four patients were identified who were diagnosed with enteric duplication cysts within the period from 2019 to 2023. Three of the patients presented with signs of intestinal obstruction-abdominal distension and pain, while one had an antenatally detected abdominal mass. There were three boys and one girl with ages ranging from 4 months to 14 years. Three cases of ileal and one case of caecal duplication cyst were reported. Most of the cases showed ileal/caecal mucosa while one case demonstrated ectopic gastric mucosa. The treatment of these cysts includes surgical excision. Although radiological investigations help in arriving at a provisional diagnosis, the final diagnosis can be confirmed only after histopathological examination. Early treatment prevents complications and results in a good prognosis for the patient. (AU)

La presentación clínica de los quistes de duplicación entérica depende de la ubicación del quiste, y los síntomas varían desde náuseas y vómitos hasta distensión abdominal, dolor y perforación. Se identificaron cuatro pacientes que fueron diagnosticados con quistes de duplicación entérica en el período de 2019 a 2023. Tres de los pacientes presentaron signos de obstrucción intestinal (distensión abdominal y dolor), mientras que uno tenía una masa abdominal detectada prenatalmente. Eran tres niños y una niña con edades comprendidas entre 4 meses y 14 años. Se notificaron tres casos de quiste de duplicación ileal y un caso de quiste de duplicación cecal. La mayoría de los casos mostraron mucosa ileal/cecal, mientras que un caso mostró mucosa gástrica ectópica. El tratamiento de estos quistes incluye la escisión quirúrgica. Aunque las investigaciones radiológicas ayudan a llegar a un diagnóstico provisional, el diagnóstico final solo puede confirmarse después del examen histopatológico. El tratamiento precoz previene complicaciones y redunda en un buen pronóstico para el paciente. (AU)

AAV-delivered hepato-adrenal cooperativity in steroidogenesis: Implications for gene therapy for congenital adrenal hyperplasia.

Despite the availability of life-saving corticosteroids for 70 years, treatment for adrenal insufficiency is not able to recapitulate physiological diurnal cortisol secretion and results in numerous complications. Gene therapy is an attractive possibility for monogenic adrenocortical disorders such as congenital adrenal hyperplasia; however, requires further development of gene transfer/editing technologies and knowledge of the target progenitor cell populations. Vectors based on adeno-associated virus are the leading system for direct in vivo gene delivery but have limitations in targeting replicating cell populations such as in the adrenal cortex. One strategy to overcome this technological limitation is to deliver the relevant adrenocortical gene to a currently targetable organ outside of the adrenal cortex. To explore this possibility, we developed a vector encoding human 21-hydroxylase and directed expression to the liver in a mouse model of congenital adrenal hyperplasia. This extra-adrenal expression resulted in reconstitution of the steroidogenic pathway. Aldosterone and renin levels normalized, and corticosterone levels improved sufficiently to reduce adrenal hyperplasia. This strategy could provide an alternative treatment option for monogenic adrenal disorders, particularly for mineralocorticoid defects. These findings also demonstrate, when targeting the adrenal gland, that inadvertent liver transduction should be precluded as it may confound data interpretation.

A Case of Type 2 Diastematomyelia With Spina Bifida in a Pediatric Female Patient.

This case report presents the clinical and radiological findings of a seven-year-old female with type 2 diastematomyelia and spina bifida, emphasizing the complexity of congenital spinal anomalies in pediatric patients. The patient presented with a two-month history of lower back pain, prompting diagnostic investigations. Radiographic examination revealed spina bifida at the L3-L5 levels, subsequently confirmed by magnetic resonance imaging (MRI), which disclosed bifid spinous processes, an absent posterior arch, and a split spinal cord terminating at the L3-L4 disc levels. The Vancouver classification system facilitated a standardized characterization of congenital spinal anomalies. The multidisciplinary approach involving orthopedic and neurosurgical specialists led to a conclusive diagnosis of type 2 diastematomyelia with simple spinal dysraphism. Surgical intervention, encompassing laminectomy and correction of the split spinal cord, was successfully performed, resulting in the stabilization of the patient. This case underscores the importance of early diagnosis, advanced imaging modalities, and collaborative management in addressing rare congenital spinal anomalies. The discussion delves into the clinical implications, diagnostic challenges, and the pivotal role of surgical intervention. Insights from this case contribute to the existing literature, guiding healthcare professionals in understanding and managing similar cases with potential implications for future research and treatment strategies.

Novel mutation of COG5 in a Taiwanese girl with congenital disorders of glycosylation manifesting as developmental delay.

We are documenting the case of An 11-year-old girl who has been followed up at our out-patient clinic since birth with clinical presentations including intrauterine growth restriction, recurrent periodic fever in infancy, hypotonia, global developmental delay, liver function impairment with cirrhotic changes, and clinodactyly. Congenital abnormalities were suspected but a series of examinations including brain MRI, liver biopsy and muscle biopsy yielded insignificant findings. Whole genome sequencing (WGS) was conducted and revealed three novel mutations (c2T > G, c1826T > C, c.556-560delAGTAAinsCT) of the COG5 gene. A diagnosis of COG5-congenital disorders of glycosylation (COG5-CDG, or CDG IIi), with neurologic presentation was established. Sanger sequencing in the patient and her parents confirmed the compound heterozygous mutation. Upon literature review, we identified the patient as the first case of COG5-CDG in Taiwan. Our study enhances the clarity of the correlation between the mutative genes and the presentation of COG5-CDG.

Small Molecule Activators of Mitochondrial Fusion Prevent Congenital Heart Defects Induced by Maternal Diabetes.

Most congenital heart defect (CHD) cases are attributed to nongenetic factors; however, the mechanisms underlying nongenetic factor-induced CHDs are elusive. Maternal diabetes is one of the nongenetic factors, and this study aimed to determine whether impaired mitochondrial fusion contributes to maternal diabetes-induced CHDs and if mitochondrial fusion activators, teriflunomide and echinacoside, could reduce CHD incidence in diabetic pregnancy. We demonstrated maternal diabetes-activated FoxO3a increases miR-140 and miR-195, which in turn represses Mfn1 and Mfn2, leading to mitochondrial fusion defects and CHDs. Two mitochondrial fusion activators are effective in preventing CHDs in diabetic pregnancy.

A Comparative Assessment of Dental Caries Experience in Relation to Nutritional Status among 6-12-year-old School-going Children and Those with Congenital Heart Disease in Bhubaneswar City.

Aim: To assess the dental caries experience in relation to nutritional status among 6-12- year-old school-going children and those with congenital heart disease in Bhubaneswar city. Materials and methods: A cross-sectional study was conducted among 6-12-year-old healthy school-going children and those with congenital heart disease for a period of 6 months (October 2019-March 2020) in Bhubaneswar, India. Type III clinical examination was carried out as per American Dental Association (ADA) specifications using plane mouth mirrors and community periodontal index (CPI) probes. Clinical oral examination and measurement of the weight and height of the child were performed by a single examiner. Data was analyzed using Statistical Package for the Social Sciences (SPSS) version 21.0. Results: The overall mean decayed missing filled primary teeth surfaces (dmfs) in primary dentition was higher (5.93 ± 10.224) in subjects with congenital heart disease (CHD) (group I) than in healthy controls (3.41 ± 6.192). The overall mean decayed missing filled permanent teeth surfaces (DMFS) in permanent dentition was 0.33 ± 1.105 in subjects with CHD (group I) and 0.24 ± 0.714 in group II. In group I, the majority of them (58.9%) were underweight, followed by 41.1% who were a healthy weight. However, in group II, 47.9% of the study subjects were healthy weight, 26.1% were underweight, 14.4% were obese, and 11.7% were overweight. Conclusion: This study concluded that children with CHD have a higher dental caries experience and poor nutritional status as compared to healthy school-going children.

Pre- and postnatal findings with rare congenital anomalies of urinary bladder.

Bladder duplication and congenital bladder diverticulum are rare anomalies. We described two boys with rare bladder anomalies found on prenatal ultrasounds. Postnatal investigations and surgical findings confirmed these bladder anomalies. The malformation was associated with other system anomalies. This report of pre- and postnatal imaging with surgical correlation contributes to our understanding about these rare bladder anomalies.

Isolated Bilateral Upper Limb Amelia - A Rare Case Report.

Introduction: Congenital upper limb amelia is one of the extremely rare conditions. It is defined as a complete absence of upper limbs. It may present as isolated or with other associated anomalies. Case Report: We present a case of a 2-year-old male child with congenital complete absence of bilateral upper limb. This male child was born after four female children. With the advancement in modern-era prenatal diagnostic facilities and a better understanding of fetal-maternal drug pharmacology, such cases are rare entity. Conclusion: Amelia is a very rare and challenging situation for clinicians. Regular prenatal checkup and knowledge of maternal and fetal drug interactions during pregnancy are key factors for prevention.

The Outcomes of Cardiac Surgery in Children With DiGeorge Syndrome in a Single Center Experience: A Retrospective Cohort Study.

Background DiGeorge syndrome, a common genetic microdeletion syndrome, is associated with multiple congenital anomalies, including congenital cardiac diseases. This study aims to identify the short and midterm outcomes of cardiac surgery performed on children with DiGeorge syndrome. Methods A retrospective cohort study was conducted between the period of 2018-2022, which included children divided into two groups with a 1:2 ratio. Group one included DiGeorge syndrome patients who were diagnosed using fluorescence in situ hybridization (FISH). Group two included the control group of patients who were clear of genetic syndromes. The two groups were matched based on similar cardiac surgery, age of surgery, and Risk Adjustment in Congenital Heart Surgery (RACHS-1) score. The two groups were compared based on the demographical data and postoperative complications. Results The study consisted of 81 children; 27 were DiGeorge syndrome patients, and 54 were in the control group. DiGeorge syndrome patients showed an increase in mechanical ventilation duration (p=0.0047), intensive care unit (ICU) length of stay (p=0.0012), and hospital length of stay (p=0.0391). Moreover, they showed an increased risk for bacteremia (p=0.0414), ventilator-associated pneumonia (VAP; p=0.0036), urinary tract infections (UTI; p=0.0064), and surgical site infection (SSI; p≤0.0001). They were also more susceptible to postoperative seizures (p=0.0049). Furthermore, patients with DiGeorge syndrome had a higher prevalence of congenital renal anomalies. However, there was no mortality in either group.  Conclusion This study shows a variability in the postoperative outcomes between the two groups. The study demonstrates that patients with DiGeorge syndrome have higher risks of infections and longer hospital stay during the postoperative period. Further research with a larger sample is needed to confirm our findings.

[Clinical features of congenitally enlarged bony portion of Eustachian tube].

Objective:To investigate the clinical features of patients with congenitally enlarged bony portions of the Eustachian tube（ET）. Methods:The medical history, physical examination, hearing test, temporal bone high resolution computed tomography（HRCT） of six patients（nine ears） with congenitally enlarged bony portion of the ET were retrospectively analyzed. Results:Four patients were men and two were women. The minimum, maximum, and average ages were 5, 21, and（14.7±6.4） years, respectively. Three malformations were bilateral and three were left-sided. Three ears had conductive hearing loss（average bone and air conduction thresholds were 13.7 dB and 71.3 dB）, three had mixed hearing loss（average bone and air conduction thresholds were 27.7 dB and 83.7 dB）, and one had extremely severe sensorineural hearing loss. The average maximum length and width of the enlarged bony ET on temporal bone HRCT were（22.61±2.94） mm and（6.50±2.33） mm, respectively. The enlargement was combined with an external auditory canal malformation in six ears, narrow tympanic cavity in six, tympanic antrum malformation in five, ossicular chain malformation in seven, cochlear malformation in six, helicotrema malformation in three, vestibule widening in two, semicircular canal malformation in three, vestibular window malformation in six, facial nerve abnormality in five, internal auditory meatus malformation in two, low middle cranial fossa in eight, and severe internal carotid artery malformation in one. Conclusion:Bony ET enlargement is a rare congenital middle ear malformation which could combined with other ear malformations. Patients can have no ET dysfunction but different patterns of hearing loss. The defect is usually found unintentionally during imaging, and the HRCT of temporal bone is significant.

Early and late outcomes of congenital biliary dilatation in pediatric patients.

BACKGROUND: This study aimed to reveal the early and late postoperative complications and outcomes after surgery for congenital biliary dilatation (CBD) by reviewing cases over the past 40 years. METHODS: We retrospectively evaluated 59 patients with CBD who underwent radical surgery for complications and outcomes, based on medical records. Early complications were defined as those requiring treatment within 5 years of the initial operation. Late complications were defined as those treated more than 5 years later. RESULTS: The median age at the first surgery was 37 months. Regarding biliary reconstruction, 54 of the 59 patients (91.5%) underwent hepaticojejunostomy. Although three patients underwent cholecystoduodenostomy and one patient underwent hepaticoduodenostomy, all were converted to hepaticojejunostomy after a median of 12.5 years. One patient developed synchronous biliary carcinoma and underwent pancreaticoduodenectomy. Early complications occurred in seven patients with 10 events (surgical site infection, n = 3 bile leakage, n = 3; ileus, n = 3; bile duct obstruction, n = 1 and intussusception, n = 1). Late complications occurred in nine patients with 12 events (ileus, n = 3; anastomotic stricture, n = 3; hepatolithiasis, n = 3; asynchronous biliary carcinoma, n = 2; pancreatolithiasis, n = 1). Two of the three patients with hepatolithiasis underwent hepatectomy refractory to the endoscopic approach. Two patients developed asynchronous biliary carcinoma at 34 and 13 years after last operation; both ultimately died of the carcinoma. Only 35 patients (61.4%) underwent a follow-up examination. A total of 11 female patients (45.8%) eventually married, and all successfully gave birth. CONCLUSION: Although the long-term prognosis is excellent with complete cyst excision and hepaticojejunostomy, we emphasize the importance of long-term follow-up.

TRAPPC11-CDG muscular dystrophy: Review of 54 cases including a novel patient.

The trafficking protein particle (TRAPP) complex is a multisubunit protein complex that functions as a tethering factor involved in intracellular trafficking. TRAPPC11, a crucial subunit of this complex, is associated with pathogenic variants that cause a spectrum of disease, which can range from a limb girdle muscular dystrophy (LGMD) to developmental disability with muscle disease, movement disorder and global developmental delay (GDD)/intellectual disability (ID), or even a congenital muscular dystrophy (CMD). We reviewed the phenotype of all reported individuals with TRAPPC11-opathies, including an additional Mexican patient with novel compound heterozygous missense variants in TRAPPC11 (c.751 T > C and c.1058C > G), restricted to the Latino population. In these 54 patients muscular dystrophy signs are common (early onset muscle weakness, increased serum creatine kinase levels, and dystrophic changes in muscle biopsy). They present two main phenotypes, one with a slowly progressive LGMD with or without GDD/ID (n = 12), and another with systemic involvement characterized by short stature, GDD/ID, microcephaly, hypotonia, poor speech, seizures, cerebral atrophy, cerebellar abnormalities, movement disorder, scoliosis, liver disease, and cataracts (n = 42). In 6 of them CMD was identified. Obstructive hydrocephaly, retrocerebellar cyst, and talipes equinovarus found in the individual reported here has not been described in TRAPPC11 deficiency. As in previous patients, membrane trafficking assays in our patient showed defective abnormal endoplasmic reticulum-Golgi transport as well as decreased expression of LAMP2, and ICAM-1 glycoproteins. This supports previous statements that TRAPPC11-opathies are in fact a congenital disorder of glycosylation (CDG) with muscular dystrophy.

Twinning International Pediatric Cardiology Fellowship Programs: A Transformative Educational Experience for Trainees with Potential for Global Adoption.

Over the last decade, having endured the COVID-19 pandemic, education and training in pediatric cardiology have undergone a profound disruptive transformation. Trainees experience considerable stress achieving all the competencies required to become a competent pediatric cardiologist. Often the quality of the training experienced by trainees, the approach to patients, and potential institutional preference in management strategy is heavily influenced by the center in which they train. We developed an online live twin program of education between Texas Children's Hospital, Houston, Texas and Children's Health at Crumlin Dublin Ireland in 2019. We explored using grounded theory whether a regular scheduled shared teaching program improved fellow education and training between both centers. Trainees were surveyed to evaluate the benefits and disadvantages of such a twin program. The majority (93%) found the sessions helpful from an educational standpoint with many trainees reporting it to be a transformative experience. Three important learning themes emerged: practice variation between centers, managing uncertainty in clinical practice and cognitive overload. This pedagogical model could be replicated across multiple international pediatric cardiology units and facilitate "collaborative learning" among centers across the globe. Furthermore, this novel educational model could also be adopted by other medical specialties.

Update on Prenatal Detection Rate of Critical Congenital Heart Disease Before and During the COVID-19 Pandemic.

Prenatal diagnosis of critical congenital heart disease (CCHD) has improved over time, and previous studies have identified CCHD subtype and socioeconomic status as factors influencing rates of prenatal diagnosis. Our objective of this single-center study was to compare prenatal diagnosis rates of newborns with CCHD admitted for cardiac intervention from the COVID-19 pandemic period (March 2020 to March 2021) to the pre-pandemic period and identify factors associated with the lack of CCHD prenatal diagnosis. The overall rate of CCHD and rates of the various CCHD diagnoses were calculated and compared with historical data collection periods (2009-2012 and 2013-2016). Compared with the 2009-2012 pre-pandemic period, patients had 2.17 times higher odds of having a prenatal diagnosis of CCHD during the pandemic period controlling for lesion type (aOR = 2.17, 95% CI 1.36-3.48, p = 0.001). Single ventricle lesions (aOR 6.74 [4.64-9.80], p < 0.001) and outflow tract anomalies (aOR 2.20 [1.56-3.12], p < 0.001) had the highest odds of prenatal diagnosis compared with the remaining lesions. Patients with outflow tract anomalies had higher odds for prenatal detection in the pandemic period compared with during the 2009-2012 pre-pandemic period (aOR 2.01 [1.06-3.78], p = 0.031). In conclusion, prenatal detection of CCHD among newborns presenting for cardiac intervention appeared to have improved during the pandemic period.

Pregnancies in patients with systemic lupus erythematosus during 2000-2018 in Finland: a case-control study.

OBJECTIVES: The aim was to investigate, how pregnancies proceed in patients with systemic lupus erythematosus (SLE) compared to their individually matched population controls. MATERIAL AND METHODS: Adult incident SLE patients were identified from the register of new special reimbursement decisions for SLE drugs in 2000-2014. For each patient, 1-3 randomly selected controls from the Population Register Centre were matched. Data regarding pregnancies were obtained from the Finnish Medical Birth Register, Care Register and Register of Congenital Malformations until 2018. The study utilized data from the Drug Purchase Register and educational information from Statistic Finland. RESULTS: A total of 163 deliveries for 103 mothers with SLE and 580 deliveries for 371 population controls were identified. The duration of pregnancies in SLE women was significantly shorter compared to controls (38.9 versus 39.6 weeks). There were more urgent Caesarean Sections. (15% versus 9%) and need for care at neonatal intensive care unit (NICU) (21% versus 11%) among deliveries in SLE mothers. No statistical difference was observed between SLE and control groups in the occurrence of preeclampsia or major congenital malformations. Gestational age was 2.5 weeks shorter when the mother experienced pre-eclampsia. Hydroxychloroquine was purchased by 30% of SLE mothers during pregnancy. CONCLUSION: The course of pregnancies in Finnish SLE patients seems to be quite moderate compared to controls, and no new safety issues were detected. The low utilization of hydroxychloroquine indicates that the benefits of the drug to pregnancy and disease course are not optimally recognized by specialists treating SLE mothers.

Electroretinography in congenital nystagmus patients with a normal fundus examination.

PURPOSE: To identify the ophthalmic causes of congenital nystagmus with normal eye examination by electroretinography (ERG). STUDY DESIGN: Retrospective observational study. METHODS: We reviewed the medical records of patients younger than 6 months of age who presented between June 2008 and November 2011 with nystagmus and no other neurological signs following an otherwise normal eye examination. A complete ophthalmic examination and ERG (Nicolet Bravo system; Nicolet Biomedial & RETIscan; Roland Instruments), fundus photography, and Ishihara color test were performed to identify any ophthalmic causes of congenital nystagmus. RESULTS: Thirty-three patients met the criteria. Rod dysfunction was diagnosed in 4 patients (12.1%), cone dysfunction in 2 patients (6.1%), and cone-rod dysfunction in 1 patient (3.0%). The results of ERG were negative in 2 patients (6.1%). Idiopathic infantile nystagmus was diagnosed in the remaining 24 patients (72.7%) based on their normal ERG examination. CONCLUSIONS: In Korean congenital nystagmus patients with a normal fundus examination, achromatopsia and Leber's congenital amaurosis are uncommon causes. ERG is needed to make a definite diagnosis and provide prognostic information in congenital idiopathic nystagmus patients with a normal fundus examination.

Diurnal 11-ketotestosterone and 17-hydroxyprogesterone saliva profiles in paediatric classical congenital adrenal hyperplasia.

OBJECTIVES: The most suitable biochemical markers for therapy adjustment in patients with congenital adrenal hyperplasia are controversial. 11-Oxygenated androgens are a promising new approach. The objective of this study was to investigate the diurnal rhythm of 11-ketotestosterone in children and adolescents in saliva and to correlate it with salivary 17-hydroxyprogesterone. METHODS: Fifty-one samples of steroid day-profiles from 17 patients were additionally analysed for 11-ketotestosterone, retrospectively. All patients were treated in our university outpatient clinic for paediatric endocrinology between 2020 and 2022. Steroid day-profiles of 17 patients could be examined. The cohort showed a balanced sex ratio. The median age was 13 years. The measurements for 17-hydroxyprogesterone were carried out during routine care by immunoassay. The measurements of 11-ketotestosterone were performed from frozen saliva samples using an implemented in-house protocol for liquid chromatography - tandem mass spectrometry (LC-MS/MS). The most important outcome were the absolute values for 11-ketotestosterone, their diurnal rhythmicity and the correlation with 17-hydroxyprogesterone. RESULTS: Both steroids show a circadian diurnal rhythm. 17-hydroxyprogesterone and 11-ketotestosterone correlate significantly. 11-Ketotestosterone showed a positive correlation with BMI at all times of the day. CONCLUSIONS: 11-Ketotestosterone shows circadian rhythmicity in our cohort and correlates with 17-hydroxyprogesterone. These findings serve as an important basis for prospective research into 11-oxygenated androgens as therapeutic markers in paediatrics. However, 11-ketotestosterone appears to be very dependent on BMI.

Immunisation deferral practices surrounding congenital heart surgery.

BACKGROUND: Perioperative immunisation administration surrounding congenital heart surgery is controversial. Delayed immunisation administration results in children being at risk of vaccine-preventable illnesses and is associated with failure to complete immunisation schedules. Among children with CHD, many of whom are medically fragile, vaccine-preventable illnesses can be devastating. Limited research shows perioperative immunisation may be safe and effective. METHODS: We surveyed Pediatric Acute Care Cardiology Collaborative member centres and explored perioperative immunisation practices. We analysed responses using descriptive statistics. RESULTS: Complete responses were submitted by 35/46 (76%) centres. Immunisations were deferred for any period prior to surgery by 23 (66%) centres and after surgery by 31 (89%) centres. Among those who deferred post-operative immunisation, 20 (65%) required deferral only for patients whose operations required cardiopulmonary bypass. Duration of deferral in the pre- and post-operative periods was variable. Many centres included exceptions to their policy for specific vaccine-preventable illnesses. Almost all (34, 97%) centres administer routine childhood immunisation to patients who remain admitted for prolonged periods. CONCLUSIONS: Most centres defer routine childhood immunisation for some period before and after congenital heart surgery. Centre specific practices vary. Immunisation deferral confers risk to patients and may not be warranted in this population. Further research would be necessary to understand the immunologic impact of these practices.

15-Year Analysis of Surgical Approaches and Outcomes for Coarctation in 132 Neonates and Infants.

A variety of surgical approaches exist to treat aortic coarctation in neonates and infants. Our institutional approach is designed to match the surgical approach to the individual anatomy of the patient. The objective of this study is to evaluate operative characteristics and outcomes of all neonates and infants who underwent surgical repair of coarctation of the aorta or hypoplastic aortic arch at University of Florida from 2006 to 2021, inclusive, either in isolation or with concomitant repair of atrial septal defect (ASD) and/or ventricular septal defect (VSD). A retrospective review was performed of 132 patients aged 0-1 year who underwent surgical repair of aortic coarctation or hypoplastic aortic arch between 2006 and 2021, inclusive, either in isolation or with concomitant repair of ASD and/or VSD. Patients were divided into two groups based on the surgical approach: Group 1 = Median Sternotomy and Group 2 = Left Lateral Thoracotomy. Continuous variables are presented as median (minimum-maximum); categorical variables are presented as N (%). The most common operative technique in Group 1 was end-to-side reconstruction with ligation of the aortic isthmus. The most common operative technique in Group 2 was extended end-to-end repair. Operative Mortality was one patient (1/132 = 0.76%). Transcatheter intervention for recurrent coarctation was performed in seven patients (7/132 = 5.3%). Surgical re-intervention for recurrent coarctation was performed in three patients (3/132 = 2.3%). From these data, one can conclude that a strategy of matching the surgical approach to the anatomy of neonates and infants who underwent surgical repair of aortic coarctation or hypoplastic aortic arch, either in isolation or with concomitant repair of ASD and/or VSD, is associated with less than 1% Operative Mortality and less than 3% recurrent coarctation requiring reoperation.

School Readiness in Preschool-Age Children with Critical Congenital Heart Disease.

This study examined the nature, variability, and predictors of school readiness difficulties in young children with critical congenital heart disease (CCHD). We hypothesized that, compared to a community control (CC) group, children with CCHD would score less well on measures of readiness and that readiness would be associated with CCHD-related risk factors. Children (60 CCHD and 60 CC) were 4 to 5 years of age and not yet attending kindergarten. Readiness measures included tests of cognition, executive function, motor ability, and pre-academic skills. Caregivers provided child behavior ratings. Analyses examined group differences in readiness, readiness profiles, and associations of readiness with CCHD-related medical risk factors. The CCHD group had lower scores than the CC group on testing and higher caregiver ratings of problems in social communication, as well as higher rates of deficits on several of the measures. Latent class analysis provided evidence for different readiness profiles, with more children with CCHD displaying profiles characterized by weaknesses in readiness. CCHD-related medical risk factors associated with readiness problems in the CCHD group included a co-morbid genetic disorder, postnatal diagnosis of CCHD, major perioperative complication, and longer periods of hospitalizations, cardiopulmonary bypass, and aortic cross-clamp placements. Findings document multiple problems in school readiness in young children with CCHD. Deficits vary across individuals and are associated with higher medical risk. Results confirm the importance of screening for school readiness in these children and suggest areas to target in designing screening measures and providing early childhood interventions.
