    Postepy Hig Med Dosw (Online) 2017 Aug;71(1):747-760
    Katedra Biochemii Klinicznej, Collegium Medicum im. Ludwika Rydygiera w Bydgoszczy, Uniwersytet Mikołaja Kopernika w Toruniu.
    Vitamin C (L-ascorbic acid) is a micronutrient best known for its anti-scurvy activity in humans. Vitamin C is involved in many biological processes involving enzymatic reactions that are catalyzed by members of dioxygenases which use Fe(II) and 2-oxoglutarate as a co-substrate.The article reviews recent data that suggest the involvement of ascorbate in dioxygenases catalyzed chromatin and DNA modifications which thereby contribute to epigenetic regulation.

    Scurvy at the agricultural transition in the Atacama desert (ca 3600-3200 BP): nutritional stress at the maternal-foetal interface?
    Int J Paleopathol 2017 Sep 23;18:108-120. Epub 2017 Jun 23.
    Universidad de Tarapacá, Instituto de Alta Investigación, Chile.
    Studies of contemporary populations have demonstrated an association between decreased dietary diversity due to resource scarcity or underutilization and an increase in diseases related to poor micronutrient intake. With a reduction of dietary diversity, it is often the women and children in a population who are the first to suffer the effects of poor micronutrient status. Scurvy, a disease of prolonged vitamin C deficiency, is a micronutrient malnutrition disorder associated with resource scarcity, low dietary diversity, and/or dependence on high carbohydrate staple-foods.

    Gingival Bleeding and Bloody Dialysate: A Case Report of Scurvy in a Child With End-Stage Renal Disease Receiving Peritoneal Dialysis.
    J Ren Nutr 2016 Nov 23;26(6):407-411. Epub 2016 Apr 23.
    Department of Pediatrics, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand.
    Patients with chronic kidney disease (CKD) or end-stage renal disease are at risk for vitamin C deficiency and scurvy due to diet restriction, increased urinary loss of the water-soluble vitamin C with diuretics, and in case of patients who are on dialysis, through dialysates. The condition may be overlooked as the clinical manifestation of scurvy may be subtle, and some presentations may mimic clinical signs in CKD. We reported a case of scurvy presenting with gingival bleeding and blood dialysate in a 6-year-old girl with end-stage renal disease who was on continuous ambulatory peritoneal dialysis. Read More

    Imaging Findings of Metabolic Bone Disease.
    Radiographics 2016 Oct;36(6):1871-1887
    From the Division of Musculoskeletal Imaging and Intervention, Department of Radiology (C.Y.C., D.I.R., S.V.K., A.J.H.), and the Pediatric Endocrine Division, Department of Pediatrics (D.M.M.), Massachusetts General Hospital, 55 Fruit St, Yawkey 6E, Boston, MA 02114; and the Department of Radiology, St. Luke's International Hospital, Tokyo, Japan (A.H.).
    Metabolic bone diseases are a diverse group of diseases that result in abnormalities of (a) bone mass, (b) structure mineral homeostasis, (c) bone turnover, or (d) growth. Osteoporosis, the most common metabolic bone disease, results in generalized loss of bone mass and deterioration in the bone microarchitecture. Impaired chondrocyte development and failure to mineralize growth plate cartilage in rickets lead to widened growth plates and frayed metaphyses at sites of greatest growth. Read More

    Vitamin C and Heart Health: A Review Based on Findings from Epidemiologic Studies.
    Int J Mol Sci 2016 Aug 12;17(8). Epub 2016 Aug 12.
    Department of Nutritional Sciences, University of Connecticut, Storrs, CT 06269, USA.
    Vitamin C is a powerful dietary antioxidant that has received considerable attention in the literature related to its possible role in heart health. Although classical vitamin C deficiency, marked by scurvy, is rare in most parts of the world, some research has shown variable heart disease risks depending on plasma vitamin C concentration, even within the normal range. Furthermore, other studies have suggested possible heart-related benefits to vitamin C taken in doses beyond the minimal amounts required to prevent classically defined deficiency. Read More

    In 1498, the Portuguese crossed the Cape of Good Hope. It was not until the period of 1633 and 1666, dates of the founding, respectively, of the Compagnie de l'Orient and the Compagnie des Indes orientales, that the way was definitively opened for trade between France and India. Because so many sailors developed scurvy after voyages that lasted 4 to 5 months, the French settled on Bourbon Island (Réunion) and Ile de France (Mauritius), to provide them with medical care.
