Objective In this currently evolving coronavirus disease 2019 (COVID-19) pandemic, the evidence is scarce about the impact of COVID-19 infection on women in labor and neonates in an inner city African-Americans (AA) population. The objective of this study was to evaluate the clinical outcomes and placental pathology in mother–infant dyads in COVID-19 cases. Study Design Retrospective chart review was conducted on 34 COVID-19 positive mother–infant dyads to study their baseline characteristics and outcomes. Placental pathology was reviewed by two perinatal pathologists. Results COVID-19 was noted in 3% of pregnant women who delivered in our institution. The majority (82%) of them were asymptomatic. Out of the four mothers who were symptomatic, only three (9%) required supplemental oxygen. None of them required invasive ventilation. All the neonates tested negative for COVID-19 at 24 hours of age. There were no gross or microscopic pathological abnormalities detected that could be definitely associated with any COVID-19 related complications during pregnancy in any of the 34 placentas. Conclusion COVID-19 does not appear to increase morbidity and mortality among pregnant women and their neonates in a predominantly AA population. Our study did not find any evidence of vertical transmission of COVID-19 infection nor any specific findings on placental pathology. Key Points

Pyruvate carboxylase (PC) enzyme deficiency is a rare genetic disorder inherited in an autosomal recessive (AR) manner. PC, a mitochondrial enzyme, converts pyruvate to oxaloacetate (OAA), which enters the tricarboxylic acid (TCA) cycle. Based on the tissue type, intermediate metabolites of the TCA cycle play a vital role in gluconeogenesis, lipogenesis, synthesis of nicotinamide adenine dinucleotide phosphate (NADPH), and neurotransmitter glutamate in the astrocytes. The severity of clinical presentation depends on the type of PC deficiency and on the residual enzyme activity. We present a term female infant admitted with refractory lactic acidosis that developed soon after birth. On biochemical evaluation, serum ammonia was 125 µmol/L; plasma amino acid analysis showed elevated citrulline, lysine, proline, decreased glutamine, and aspartic acid; urine organic acid analysis showed markedly increased lactic acid, and moderately elevated 3-hydroxy-butyric and acetoacetic acid. MRI brain demonstrated abnormal diffuse white matter edema, loculated and septate large cysts along the caudothalamic notch as well as lateral aspect of the frontal horn bilaterally. Magnetic resonance (MR) spectroscopy showed large amounts of lactate peak. Molecular genetic analysis showed two pathogenic variants in the PC gene confirming the diagnosis of PC enzyme deficiency. The infant was discharged home on palliative and hospice care, and she died on the 22 nd day after birth.

Objectives Extracorporeal membrane oxygenation (ECMO) is an increasingly used mode of critical care support for pediatric patients refractory to conventional therapy. We evaluated the characteristics, outcomes, and readmissions rates for pediatric ECMO in the United States. Methods Data was extracted from the Nationwide Readmissions Database, a database designed to support national readmissions analyses, for patients aged 1–18 years undergoing ECMO between 2012–2018. Baseline demographics, comorbidities, and characteristics were identified using International Classification of Diseases codes. Results Out of 897,117 index pediatric hospitalizations, 3706 patients underwent ECMO [median age 9 years (IQR 2,15); 51.6% males]. 2246 (60.6%) patients survived to hospital discharge, with a 30-day readmissions rate of 17% among survivors. Cardiac conditions associated with ECMO were congenital heart disease (25.3%), cardiogenic shock (23.6%), and congestive heart failure (16.2%). The common respiratory associations were sepsis (36.2%), pneumonia (35.6%), and asthma (15.4%). Patients who survived were more likely to have diagnoses of asthma, bronchiolitis, myocarditis, pneumonia, and sepsis. Acute kidney injury (51.5%), disseminated intravascular coagulation (22.5%), and surgical site bleeding (12.7%) were the commonly associated complications. The trend for yearly survival rates was not statistically significant (linear p-trend = 0.38). Conclusions Pediatric ECMO continues to be associated with notable mortality and complication rates. We did not observe a meaningful trend for the yearly survival rates over the study period, and over one-sixth of survivors were readmitted within 30-days. More research is needed to identify patients at high risk of mortality and readmissions, to help target resources more efficiently and improve survival.

Hypernatremic dehydration in neonates is a common condition in an exclusively breastfed infant but often underdiagnosed. Any newborn who has lost more than 10% of birthweight should be carefully evaluated and monitored for clinical features of dehydration. Efforts such as frequent follow-up for weight check, and formula supplementation, if needed, should be provided to a neonate at risk of developing complications of dehydration. Adequate lactation consultation, both inpatient and outpatient, should also be provided, especially to the primigravida mother. Here, we present a case of a neonate with severe hypernatremic dehydration caused by inadequate lactation in a primigravida mother, which resulted in cerebral venous sinus thrombosis leading to significant intracerebral hemorrhage. The infant suffered permanent neurologic damage and was sent home on technological devices (tracheostomy and gastrostomy tubes). Further, we provide a brief review of hypernatremic dehydration and sinus venous thrombosis in neonates.

Neonatal diabetes mellitus (NDM) is a rare condition with more than 20 monogenic genes associated with it. GLIS3 gene-encoded GLI similar protein 3, as a transcription factor, is involved in the development of the pancreas, liver, kidneys, eye, and thyroid. We report a preterm female neonate with coarse facial features and hyperglycemia, later diagnosed with neonatal diabetes mellitus, congenital hypothyroidism (CH), congenital glaucoma (CG), and renal cysts, secondary to GLIS3 gene mutation. It is a rare genetic disorder involving multiple organ systems with progressive development of symptoms requiring long-term surveillance and management.
