Oral Manifestations of Vitamin C Deficiency in a Toddler.

Vitamin C deficiency, colloquially known as scurvy, has become rare in modern times due to the widespread availability of ascorbic acid-rich foods. Despite this, it continues to be a concern in certain at-risk populations. The purpose of this report is to describe the case of a two-year-old girl who initially presented to a pediatric dental clinic with the chief complaint of hypertrophic gingiva and bleeding.

Phase partitioning of the neutrophil oxidative burst is coordinated by accessory pathways of glucose metabolism and mitochondrial activity.

Neutrophils are a part of the innate immune system and produce reactive oxygen species (ROS) to extinguish pathogens. The major source of ROS in neutrophils is NADPH oxidase, which is fueled by NADPH generated via the pentose phosphate pathway; however, it is unclear how other accessory glucose metabolism pathways and mitochondrial activity influence the respiratory burst. We examined the temporal dynamics of the respiratory burst and delineated how metabolism changes over time after neutrophil activation.
