Documento de consenso SEIP-AEPAP-SEPEAP sobre la etiología, el diagnóstico y el tratamiento de las infecciones cutáneas bacterianas de manejo ambulatorio / SEIP-AEPAP-SEPEAP consensus document on the aetiology, diagnosis and treatment of bacterial skin infections in out-patients

Las infecciones cutáneas constituyen un motivo de consulta frecuente en dermatología pediátrica. Se revisan las manifestaciones clínicas, el diagnóstico y el tratamiento de los principales cuadros infecciosos bacterianos de la piel, así como de la sobreinfección de las heridas punzantes y por mordedura. Las bacterias más prevalentes en las infecciones cutáneas son Staphylococcus aureus (S. aureus) y Streptococcus pyogenes. El tratamiento es generalmente empírico y solo ante determinadas circunstancias o mala evolución clínica se recomienda el estudio microbiológico. Las infecciones cutáneas superficiales pueden tratarse con antisépticos y antibióticos tópicos (mupirocina o ácido fusídico). El tratamiento sistémico se reserva para formas extensas, graves o con otros factores de riesgo del huésped. En estos casos, el antibiótico de elección dependerá, entre otros factores, de los patógenos sospechados; los más utilizados son penicilina, amoxicilina, amoxicilina-ácido clavulánico y cefalosporinas de primera o segunda generación. Considerando la baja incidencia de S. aureus resistente a la meticilina de adquisición comunitaria en nuestro país, no se recomienda modificar el tratamiento empírico salvo en circunstancias de especial gravedad, recurrencia o antecedente epidemiológico, en cuyo caso el tratamiento recomendado es clindamicina o trimetoprima-sulfametoxazol

Skin infections are a common cause for dermatological consultations in the paediatric setting. A review is presented of the clinical manifestations, diagnosis and treatment of the main bacterial skin infections, as well as the diagnosis and treatment of super-infected puncture and bite wounds. The most prevalent bacteria in skin infections are Staphylococcus aureusand Streptococcus pyogenes. Treatment is usually empirical, since microbiological studies are only recommended under certain circumstances or lack of improvement with common therapies. Superficial skin infections can be treated with local antiseptics or antibiotics (mupirocin or fusidic acid). Systemic treatment is usually reserved for patients with extensive or severe disease or with other risk factors. Systemic treatment depends on the suspected infecting bacteria, with penicillin, amoxicillin, amoxicillin-clavulanic acid and first or second generation cephalosporin being the most frequently used drugs. Due to the low incidence of community-acquired methicillin-resistant infection by S. aureus in Spain, the use of clindamycin or co-trimoxazole is only recommended after severe disease, relapses or a clear epidemiological background

[Study of bacteriology and resistances in pediatric appendicitis]. / Estudio de la flora patógena y resistencias en apendicitis pediátricas.

UNLABELLED: There is controversy about the convenience of performing a bacteriological peritoneal culture in pediatric appendicitis. We performed a sero-epidemiological survey of the bacteria found in peritoneal swabs from pediatric appendicitis operated in our hospital. METHODS: Ambispective study. Retrospective revision of the bacteriological results from peritoneal swabs performed in pediatric appendicitis from january 2009 to december 2010 (2 years) and prospective study of peritoneal swabs collected between january 2011 and december 2011 (one year). RESULTS: We found 728 pediatric patients (mean age 7.1, range: 2-11 years). Among these, 108 were < 5 years. Cultures were performed in 328 (45.1%). A positive result was found in 155 swabs, (47.3%). Positive cultures were more frequent in patients < 5 years (69.2% vs 40.4%, p < 0.001). The most frequent pathogens were E. coli: 122 specimens, Streptococcus spp (50 swabs), P. aeruginosa: (45) and B.fragilis: (35) Younger age was strongly associated with P. aeruginosa: (30.8% vs 8.4%, p < 0.001. OR: 4.8. IC 95%: 2.3-9.8). So was the detection of E. coli (50% vs 33.2% p = 0.01). 21.3% (26 swabs) of E. coli were resistant to amoxicillin-clavulanic acid. There were 15 (12.3%) multiresistant (ESBL) E. coli. Among the Streptococcus, 32% (16 out of 50) were resistant to clindamicin, and so were 28.6% of the B. fragilis (10 out of 35). DISCUSSION: . The most frequent pathogens were E. coli, Streptococcus spp and P. aeruginosa. P. aeruginosa is five times more frequent in patients < 5 years. Resistance of E. coli to amoxiclavulanate was high: 21.3% of the specimens. We found that 12.3% of the E. coli produced ESBL.

Objetivos. Existe controversia sobre la utilidad del cultivo de líquido peritoneal en las apendicitis pediátricas. Hemos investigado la situación epidemiológica de la fl ora bacteriana en las apendicectomías pediátricas. Material y métodos. Revisión retrospectiva de apendicectomías realizadas en menores de 12 años, en dos años (enero/2009-diciembre/2010) y análisis prospectivo durante un año (enero/2011-diciembre/2011). Resultados. Encontramos 728 pacientes (media 7,1 años, rango 2-11). De ellos, 108 eran <5 años. Se recogió cultivo de líquido perineal en 328 (45,1%). Los cultivos fueron positivos en 155 de esas 328 muestras (47,3%). Fue más frecuente encontrar cultivo positivo en <5 años (69,2% vs. 40,4%, p <0,001. OR: 3,3. IC 95%: 1,8-5,9). Las bacterias más habituales fueron Escherichia coli, con 122 aislamientos, Streptococcus spp (50 aislamientos), P. aeruginosa, (45 aislamientos) y B. fragilis (35). La frecuencia de P. aeruginosa fue cinco veces mayor en el grupo de < 5 años (30,8% vs. 8,4%, p<0,001. OR: 4,8. IC 95%: 2,3-9,8). Asimismo, la presencia de E. coli se duplicó en el grupo de < 5 años (50% vs. 33,2% p = 0,01. OR: 2,01. IC 95%: 1,1-3,4). 26 (21,3%) especímenes de E. coli eran resistentes a amoxicilina-clavulánico. Hubo 15 (12,3%) cepas de E. coli multirresistentes. 16 cepas de Streptococcus (32%) y 10 aislamientos de B. fragilis (28,6%) fueron resistentes a clindamicina. Conclusiones. En < 5 años existe más riesgo de infección por Pseudomonas. Encontramos una alta tasas de resistencia de E. coli a la amoxicilina-clavulánico y 12,3% de E. coli eran multirresistentes
