Multiple chemical sensitivity in an 8-year-old girl. A 6-year follow-up

Multiple chemical sensitivity (MCS) is a controversial little understood entity. MCS is a multisystem and poly-symptomatic syndrome. MCS subjects display a complex symptomatology due to the intolerance of chemical agents.

Symptoms include general discomfort, cardiovascular instability, sensory organs irritation, breath disorders, hypersensitivity affecting the skin and epithelial lining of the gut, throat and lungs.

We report the case of an 8 years old female, assessed in medical consultation for chemical sensitization when presenting inhalation and pharyngeal symptoms, conjunctivitis, dysphonia, coughing spells and respiratory distress.

A 6-year follow-up was carried out and the provocation inhaler test which was performed twice among that period obtained the same conclusive results for the diagnosis of MCS.

The case submitted meets the criterion of MCS, being exceptional a debut of the symptons at such an early age.
