[Clinical score to rule out pneumonia due to Mycoplasma pneumoniae]. / Score clínico para el descarte de neumonía por Mycoplasma pneumoniae.

INTRODUCTION: The gold standard for the diagnosis of pneumonia secondary to Mycoplasma pneumoniae is the serial measurement of IgM, since an isolated test for IgM has a poor sensitivity of 31.8%. A pneumonia due to Mycoplasma pneumoniae could be of clinically different origins, thus it is possible to perform a clinical score for its early diagnosis. OBJECTIVE: To develop a clinical score in order to rule out a pneumoniae secondary to Mycoplasma pneumoniae. METHODOLOGY: A total of 302 patients from 0 to 18 years-old, with a diagnosis of pneumonia were evaluated and divided into two groups: Mycoplasma positive and Mycoplasma negative. Using different variables in the medical records a clinical score was calculated. RESULTS: Of the 302 cases studied, 34 were classified as Mycoplasma positive and 268 as Mycoplasma negative. The variables relevant to the calculation of the score were age, days with fever, and days with cough, thus providing the CAF (Cough, Age, Fever) score. Ranges were assigned for each variable and points were given for each range. A value greater than or equal to 5 meant a positive score. The CAF score was applied to the 302 cases, resulting in 164 cases of Mycoplasma positive and 138 cases of Mycoplasma negative. The CAF score had a sensitivity of 85% and specificity of 49%. CONCLUSION: The CAF score had better sensitivity than other clinical diagnostic tools. With a negative predictive value of 96% it is possible to rule out a pneumonia secondary to M. pneumoniae. The study requires a prospective study to verify the usefulness of our score.

Manifestaciones cutáneas de la enfermedad inflamatoria intestinal / Skin manifestations of pediatric inflammatory bowel disease

La enfermedad inflamatoria intestinal (enfermedad de Crohn [EC], colitis ulcerosa, colitis indeterminada o enfermedad inflamatoria intestinal no clasificada) se acompaña de manifestaciones cutáneas hasta entre el 10 y el 15% de los casos. Hay pocos datos de prevalencia de éstas en poblaciones pediátricas, si bien algunos estudios recientes calculan que pueden estar presentes hasta en el 8% de los casos en el diagnóstico. El objetivo de este estudio es comunicar diferentes formas de manifestaciones cutáneas observadas en los pacientes pediátricos con enfermedad inflamatoria intestinal. El caso 1 se trata de un eritema nudoso de aparición al comienzo de la EC. Tiene una presentación típica en forma de nódulos eritematosos dolorosos de localización pretibial; su respuesta es buena y desaparece tras el inicio del tratamiento con infliximab. El caso 2 se trata de un caso con coexistencia de pioderma gangrenoso y síndrome de Sweet de afectación mucocutánea en un paciente con EC. La evolución de las lesiones es rápidamente progresiva y se controla con esteroides sistémicos. Se observa la presencia de importantes lesiones cicatriciales residuales. Los casos 3 y 4 se tratan de EC metastásica en glúteo y vulva, respectivamente, con buena respuesta al tratamiento con infliximab (AU)

Skin manifestations have been described in 10–15% of patients with inflammatory bowel disease (Crohn's disease, ulcerative colitis, indeterminate colitis/inflammatory bowel disease type unclassified). There are limited data on the prevalence of these manifestations in paediatric patients, but recent studies have reported its presence in 8% of them at diagnosis. Our aim is to report the different skin manifestations observed in our paediatric patients with inflammatory bowel disease. Case 1: Erythema nodosum at Crohn's disease diagnosis. Typical presentation with painful erythematous nodules in the pretibial region and with good response to infliximab. Case 2: Coexistence of pyoderma gangrenosum and mucocutaneous Sweet's syndrome in a Crohn's disease patient. A rapidly progressive disease that was controlled with systemic steroids but with significant residual lesions. Case 3 and 4: Metastatic Crohn's disease with good response to infliximab (AU)
