Background: Findings from manometry studies and contrast imaging reveal functioning gastric physiology in newborns with duodenal atresia and stenosis. Stomach reservoir function should therefore be valuable in aiding the postoperative phase of gastric feeding. The aim of this study was therefore to compare the feasibility of initiating oral or large volume(s) gavage feeds vs small volume bolus feeds following operation for congenital duodenal anomalies.

Stenting of the gastric outlet is an accepted method for palliation of symptoms secondary to inoperable malignancy and is successful in most cases. Failure of stenting is most commonly due to inability to cross the stricture. We describe a rendezvous technique of duodenal stenting via transhepatic biliary access when conventional endoscopic or fluoroscopic methods fail. Read More

Biallelic loss-of-function (LoF) variants in CENPF gene are responsible for Strømme syndrome, a condition presenting with intestinal atresia, anterior ocular chamber anomalies, and microcephaly. Through an international collaboration, four individuals (three males and one female) carrying CENPF biallelic variants, including two missense variants in homozygous state and four LoF variants, were identified by exome sequencing. All individuals had variable degree of developmental delay/intellectual disability and microcephaly (ranging from -2. Read More

Fanconi anemia (FA) is caused by pathogenic variants in the FA/BRCA DNA repair pathway genes, and is characterized by congenital abnormalities, bone marrow failure (BMF) and increased cancer risk. We conducted a genotype-phenotype and outcomes study of 203 patients with FA in our cohort. We compared across the genes, FA/BRCA DNA repair pathways (upstream, ID complex and downstream), and type of pathogenic variants (hypomorphic or null). Read More

VACTERL Syndrome affects multiple body systems and can include various anomalies of the Vertebral column, Anus and/or rectum, heart (Cardiac), Tracheo-Esophagus, kidneys (Renal), and Limbs. Patients with VACTERL syndrome are at increased risk of having a congenital duodenal obstruction that may be extrinsic in the form of an annular pancreas or intrinsic in the form of duodenal atresia, stenosis or web. Simultaneous presentation of both the annular pancreas and duodenal web is a rare clinical entity and typically presents in neonates. Read More

Purpose: To assess associations between influenza vaccination during etiologically-relevant windows and selected major structural non-cardiac birth defects.

Study Design: We analyzed data from the National Birth Defects Prevention Study, a multisite, population-based case-control study, for 8233 case children diagnosed with a birth defect and 4937 control children without a birth defect with delivery dates during 2006-2011. For all analyses except for neural tube defects (NTDs), we classified mothers who reported influenza vaccination 1 month before through the third pregnancy month as exposed; the exposure window for NTDs was 1 month before through the first pregnancy month.

Microphthalmia is a rare ocular anomaly with a poorly understood etiology that is most likely related to heritable and/or environmental factors. Many papers have been published pertaining to the clinical manifestations and management of this condition; however, few reports have reported detailed histopathological findings, which are the focus of this study, in addition to highlighting the basic demographics in these cases. This was a retrospective, observational study of all consecutive enucleated microphthalmic globes (with or without cysts) at 2 tertiary eye hospitals in Riyadh, Saudi Arabia. Read More

Background: MRS/MFS is a rare multisystem disorder with a poor prognosis. The high mortality rate of this syndrome is related to the severity of the associated gastrointestinal, pancreatic, and hepatobiliary conditions, as most of them are not amenable to conventional medical and surgical treatments.

Methods: We report the case of a Romani girl with all the key clinical features of MRS/MFS, and a review of cases reported in the literature. Read More

Aim: Despite data to suggest benefit of trans- anastomotic tube (TAT) feeding in infants following repair of congenital duodenal obstruction (CDO), TAT usage is limited. We aimed to report a large series of infants with CDO treated with or without TAT in order to improve the evidence underlying this simple intervention.

Background: There is a paucity of data on the frequency of transfusion during pediatric surgery index cases and guidelines for pretransfusion testing, defined as type and screen and crossmatch testing, prior to operation are not standardized. This study aimed to determine the incidence of perioperative blood transfusions during index neonatal operations and identify risk factors associated with perioperative blood transfusion to determine which patients benefit from pretransfusion testing.

Methods: A retrospective review of infants who underwent index neonatal cases between 2013 and 2019 was performed. Read More

Duodenal stenosis and atresia are some of the most common forms of congenital bowel obstruction. The gold standard approach to treatment is duodenoduodenostomy, while rare, gastrojejunostomy and duodenojejunostomies may still be used. We report a case of a 7-year-old male presenting with annular pancreas with duodenal stenosis that was diagnosed at birth as primary duodenal atresia and repaired by gastrojejunostomy with a Braun enteroenterostomy.
