Scurvy -gulonolactone oxidase (GULO) enzyme, which is required in the last step of vitamin C synthesis. The genomes of these species contain GULO as pseudogenes, which serve as insight into the evolutionary past of the species. In babies, scurvy is sometimes referred to as Barlow's disease, named after Thomas Barlow, a British physician who described it in 1883. However, Barlow's disease or Barlow's syndrome may also refer to mitral valve prolapse, first described by John Brereton Barlow in 1966. Scurvy Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms include weakness, feeling tired, and sore
Vitamin K appear to be much lower than those of vitamin K. Occurrence of vitamin K deficiency bleeding in the first week of the infant's life is estimated at 0.25–1.7%, with a prevalence of 2–10 cases per 100,000 births. Premature babies have even lower levels of the vitamin, so they are at a higher risk from this deficiency. Bleeding in infants due to vitamin K deficiency can be severe, leading to hospitalization, blood transfusions, brain damage, and death. Supplementation can prevent most cases of vitamin K deficiency bleeding in the newborn. Intramuscular administration (known as the "Vitamin K shot") is more effective
