SummaryInherited antithrombin III (AT-II, heparin cofactor) deficiency is a rare condition, presenting with thrombotic disease in adult life. This paper reports an 8 months old South African Black male infant with multiple large vessel venous and arterial thromboses, and E. coli septicaemia. This was associated with an extremely low plasma AT-II level. Micronodular cirrhosis and intracytoplasmic hyaline globules in the liver cells were present. These globules were eosinophilic, and PAS-positive after diastase. They measured approximately 5 μ to 30 μ in diameter, occurred singly in the liver cells and were located mainly in the periportal areas. The histological findings in the liver are similar to those observed in α1-antitrypsin (AAT) deficiency in which the intracytoplasmic globules represent accumulation of altered AAT. Immunochemical studies carried out on formalin fixed tissue failed to detect cross reaction material with anti-α1 antitrypsin or anti-AT III antiserum. This is the first case report of AT-III deficiency presenting in infancy. It is also the first case associated with distinctive liver pathology.The available data presented are insufficient to distinguish between an inborn defect and acquired causes of the severely depressed AT-III plasma level and the distinctive liver pathology.

Introduction During the Coronavirus Disease 2019 global pandemic, maternal and newborn wellbeing has received much attention. Detailed reports of infected women breastfeeding their infants are uncommon. Due to incomplete information available, full data about those infants’ outcomes are lacking, and evidence of infectivity through breastfeeding has not been documented. Main Issue Here, we report about a mother who breastfed her infant until she was confirmed with the SARS-Cov-2 infection. After follow-up, we have confirmed that the infant, who was breastfed by the infected mother, was not infected. Methods A 33-year-old woman gave birth to a full-term male infant on November 8, 2019. Since birth, she had been exclusively breastfeeding the baby until she was confirmed with the SARS-Cov-2 infection on February 8, 2020. She was hospitalized, isolated from her baby, and stopped breastfeeding. Even though she remained asymptomatic, her milk was expressed using a breast pump and discarded. The mother’s milk sample was collected on February 9, 2020, and the result of the nucleic acid test for COVID-19 was negative. Her infant was asymptomatic and remained virus negative. Her laboratory findings and chest Computed Tomography imaging was normal. She was treated according to the national protocol with aerosolized interferon α2β, lopinavir/ritonavir and ribavirin. Her serum SARS-CoV-2 specific antibodies(IgG and IgM) tested positive when discharged. She returned to breastfeeding after discharge. Conclusion Our findings suggest that breastfeeding may be less of a risk than anticipated. Additional research is needed to explore this possibility.

AbstractObjectivesNeonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes that is usually diagnosed in the first six months of life.Case presentationWe report on a male infant with neonatal diabetes who presented with diabetic ketoacidosis at two months and 16 days. A novel homozygous missense mutation (c.259T>G) was identified in the ABCC8 gene. In this case, insulin was replaced with glimepiride at a dosage of 0.49 mg/kg/day at five months, and this achieved metabolic control and satisfactory growth as observed at follow-up.ConclusionsThis report improves our understanding of the mutational spectrum of ABCC8, which is normally associated with NDM, and shows that the treatment regimen for this condition can be successfully switched from insulin therapy to the use of sulfonylurea.

Abstract The clinical and laboratory features of a 3-mo-old black male infant with glutathione (GSH) synthetase deficiency of the generalized type was evaluated. Partial albinism, brisk hemolytic anemia, recurrent febrile episodes, and mental retardation were noted. Also, severe recurrent metabolic acidosis and marked oxoprolinemia and oxoprolinuria were found in the proband but not in his first-degree relatives. The relationship of these disease manifestations to the underlying metabolic defect is discussed.

Aggression is controlled by the olfactory system in many animal species. In male mice, territorial and infant-directed aggression are tightly regulated by the vomeronasal organ (VNO), but how diverse subsets of sensory neurons convey pheromonal information to limbic centers is not yet known. Here, we employ genetic strategies to show that mouse vomeronasal sensory neurons expressing the G protein subunit Gαi2 regulate male–male and infant-directed aggression through distinct circuit mechanisms. Conditional ablation of Gαi2 enhances male–male aggression and increases neural activity in the medial amygdala (MeA), bed nucleus of the stria terminalis, and lateral septum. By contrast, conditional Gαi2 ablation causes reduced infant-directed aggression and decreased activity in MeA neurons during male–infant interactions. Strikingly, these mice also display enhanced parental behavior and elevated neural activity in the medial preoptic area, whereas sexual behavior remains normal. These results identify Gαi2 as the primary G protein α-subunit mediating the detection of volatile chemosignals in the apical layer of the VNO, and they show that Gαi2+ VSNs and the brain circuits activated by these neurons play a central role in orchestrating and balancing territorial and infant-directed aggression of male mice through bidirectional activation and inhibition of different targets in the limbic system.
