“…En niños mayores, otras causas raras de estridor pueden incluir anafilaxia, deficiencia de C1 esterasa, hipocalcemia puede producir aducción espasmódica de las cuerdas vocales resultando en la obstrucción de la vía aérea superior y estridor. La hipocalcemia como causa de estridor es rara, y en la edad pediátrica, es más frecuente en los grupos neonatales cuando es generalmente secundario a un hipoparatiroidismo parcial transitorio (12).…”

Estridor es un sonido musical, de alta frecuencia, generado por el paso de un flujo de aire turbulento en zonas con calibre disminuido de la vía aérea de mayor tamaño.La causa del estridor puede estar localizado en cualquier lugar de la vía aérea extratorácica (nariz, faringe, laringe y tráquea) o la vía aérea intratorácica (árbol traqueobronquial). El estridor puede ser agudo (causado por inflamación/infección o aspiración de cuerpos extraños) o crónica. Puede ser congénita o adquirida.Varios trastornos congénitos y adquiridos prevalecen en neonatos, lactantes, niños y adolescentes, y tienen que ser distinguidos. La historia clínica, edad del niño y examen físico a menudo permiten un diagnóstico presuntivo. Puede requerirse mayor estudio para establecer un diagnóstico definitivo, y la endoscopia flexible de la vía aérea es el procedimiento diagnóstico de elección en la mayoría de las circunstancias.

A 16-month-old boy was referred to the emergency department of the Children's Clinical University Hospital (Riga, Latvia) due to cough and noisy breathing for 3 months. The complaints seemed to have worsened over time with coughing fits 2–4 days a week and the boy not being able to tolerate solid food (leading to vomiting) during the fits. In between the bouts, he felt fine. Diminished food intake was noted over the last month. Over the 3-month period, no other symptoms were noted. The father of the child was fixated on a diagnosis of asthma and categorically denied the possibility of any choking attacks after eating or playing with small objects. The boy had been seen by pulmonologist once over the preceding 3-month period and was treated with salbutamol and high-dose fluticasone propionate inhalations that offered no alleviation of the symptoms. No imaging studies had been performed.

Although stridor is a common respiratory symptom associated with upper respiratory diseases, yet its relation with hypocalcemia is not widely appreciated. The mechanism of hypocalcemia in causing stridor might be a collapsing of larynx most likely caused by decalcifi cation due to hypocalcemia. Vitamin D defi ciency causes a reduction in serum calcium, which stimulates the production of extra PTH to mobilize and maintain calcium from bone and cartilage for more vital cells of the body, brain, heart and blood. Stridor might appear with upper respiratory tract infection, accordingly the role of hypocalcemia as a cause of stridor might not be recognized. Infants are born with poor vitamin D in places with high prevalence of vitamin D defi ciency due to environmental, social, customs and housing factors. Due to maternal vitamin D defi ciency, breast milk is low in vitamin D which leads to poor absorption of calcium. Stridor caused by hypocalcemia should be considered as a warning sign to prevent more serious complications as cardiomyopathy, myelofi brosis, and convulsions. In communities with high prevalence of vitamin D defi ciency checking for hypocalcemia should be part of the work up, when stridor is the presenting symptom in infants. The mechanism by which hypocalcemia causes stridor might be laryngiomalacia.
