An 8-year-old boy with autism developed a limp and periorbital swelling. He was found to have hypocalcemia and radiographic evidence of rickets. Ophthalmologic examination revealed xerophthalmia and corneal erosions. Serum vitamin A was undetectable and serum 25-hydroxyvitamin D was decreased. Dietary history revealed a markedly altered intake consisting of only french fried potatoes and water for several years. All biochemical and physical abnormalities reversed with appropriate supplementation. The nutritional content of french fries is reviewed. Feeding dysfunction is an integral part of autism and closer attention should be paid to potential nutritional deficiencies.

Syphilis cases in the UK have risen from 301 in 1997 to 3,702 in 2006. After the autism scare of 1998, uptake of both doses of the MMR vaccine fell to 80 percent. Blackburn with Darwen PCT spent pound160,000 on vitamins after seeing a case of rickets every week.

Vitamin D deficiency is common in the general population and even more frequent in patients with chronic diseases. The prevention of rickets with native vitamin D supplementation is one of the oldest and most effective prophylactic measures ever reported in medicine, leading to an almost complete eradication of vitamin D-deficient rickets in developed countries. We report on two children with vitamin D abnormalities: the first, 10-year-old child developed rickets without any vitamin D supplementation despite different risk factors (autism, ethnicity, nutritional problems, chronic antiepileptic therapies). In contrast, the second, 8-month-old child received double doses of native vitamin D from birth for several months and was referred for acute and symptomatic hypercalcemia. As such, vitamin D supplementation must follow specific rules: neither too much nor too little! We also discuss the emergence of "new" genetic diseases such as mutations in the 24-hydroxylase (CYP24A1) gene inducing neonatal hypercalcemia and nephrocalcinosis: we believe that before prescribing conventional vitamin D supplementation as recommended by the national guidelines, pediatricians should quickly rule out a potential genetic abnormality in phosphate/calcium metabolism (namely a history of lithiasis or hypercalcemia) that would lead to further biological investigations.

Vitamin D, a secosteroid, is essential for the development and maintenance of healthy bone in both the adult and pediatric populations. Low level of 25-hydroxy vitamin D (25-(OH)-D) is highly prevalent in children worldwide and has been linked to various adverse health outcomes including rickets, osteomalacia, osteomalacic myopathy, sarcopenia, and weakness, growth retardation, hypocalcemia, seizure and tetany, autism, cardiovascular diseases, diabetes mellitus, cancers (prostate, colon, breast), infectious diseases (viral, tuberculosis), and autoimmune diseases, such as multiple sclerosis and Hashimoto's thyroiditis. Risk factors for hypovitaminosis D are people with darker skin pigmentation, use of sunscreen, insufficient ultraviolet B exposure, prematurity, living in northern latitudes, malnutrition, obesity, exclusive breastfeeding, low maternal vitamin D level, certain medications, drinking unfortified cow's milk, liver failure, chronic renal insufficiency, cystic fibrosis, asthma, and sickle cell hemoglobinopathy. This review highlights and summarizes the molecular perspectives of vitamin D deficiency and its potential adverse health outcomes in pediatric age groups. The recommended treatment regimen is beyond the scope of this review.

Rickets due to vitamin D deficiency, typically presenting as bowed legs in toddlers, is uncommon in the modern era. We describe the case of a nine-year-old girl with autism and developmental delay who was evaluated for chronic intermittent extremity pain for more than one year prior to referral to the emergency department for hypocalcemia and increased alkaline phosphatase, which eventually led to the diagnosis of rickets confirmed by radiographic and laboratory findings. This report highlights the importance of the patient's history of developmental delay and autism in the evaluation and approach to limb pain, and discusses the appropriate diagnostic approach.
