Hand-foot and mouth disease and reactive arthritis: an unusual paediatric case

Reactive arthritis is defined as arthritis that occurs during or after an extraarticular infection. It is mostly difficult to determine the causative agent that causes inflammation in the joints. Initially, salmonella, shigella, chlamydia and Yersinia were considered to be pathogenic agents. But recently, in addition to demonstrated viral and bacterial agents, there are also other cases of reactive arthritis after vaccinations with Rubella and Influenza. Herein a 3-year old boy is reported with reactive arthritis of left knee that developed shortly after hand-foot and mouth disease. This report represents the first detailed description of a paediatric case in literature with reactive arthritis following hand-foot and mouth disease

Una causa infrecuente de convulsión hipocalcémica: raquitismo congénito. Caso clínico / An uncommon cause of hypocalcemic convulsion: congenital rickets. Case report

La deficiencia de vitamina D y el raquitismo son problemas de salud importantes en los países en desarrollo. El raquitismo congénito es una forma infrecuente de raquitismo. La deficiencia materna de vitamina D es el factor de riesgo más importante para la deficiencia de vitamina D y el raquitismo en los recién nacidos y lactantes. Presentamos el caso de un niño de 2 meses de edad, con convulsiones durante su hospitalización por neumonía. Se diagnosticó raquitismo congénito asociado a deficiencia materna de vitamina D.

Vitamin D deficiency and rickets are major health problems in developing countries. Congenital rickets is a rare form of rickets. Maternal vitamin D deficiency is the most important risk factor for vitamin D deficiency and rickets in newborns and early infancy. In this report, we presented a two-monthold infant with seizures while hospitalized for pulmonary infection. Finally, congenital rickets due to maternal vitamin D deficiency was diagnosed.
