Introduction:The Café au lait spots (CALS) are shown in the normal population without pathological significance, although they could also be criteria for some neurologic syndromes. Unspecific association with general neurologic illnesses has been less frequently described. We want to know in which measure, the presence of isolated CALS represents a risk factor for neurological disease.
Patients and methods:We set up an observational transversal study of cases, patients admitted for neuropaediatric reasons (NPP; n=49) excluding all the patients suffering from neurologic illnesses associated to CALS, and controls, a hospital simultaneously admitted pediatric population for non-neurologic causes (CP; n=101) since October 2012 to January 2013. The data were collected from the clinical reports at admission, and then analyzed by SPSS 22.0 statistical package, and the Stat Calc module of EpiInfo 7.0, following the ethics current rules of the institution for observational studies.Results: Twelve out of 49 NPP (24.4%) showed at least one CALS, while only 10 out of 101 PC (9.9%) (OR= 4.38; IC=1.03-19.74) did it, being the probability of showing CALS at least 4 times significantly higher in the NPP group than in the CP group. The epileptic patients (Χ2=14.19; p=0.0002) and those admitted for encephalopathy studies (Χ2=45.7; p=0.000000) showed a significantly higher prevalence of de CALS.
Conclusion:The prevalence of CALS was significantly higher among the patients admitted because of neurologic problems excluding syndromes or illnesses associated to them.
