Bloodstream Infection in Children With Epidermolysis Bullosa.

BACKGROUND: Epidermolysis bullosa (EB) is frequently complicated by skin infection, which can lead to bacteremia. However, bloodstream infections (BSI) in patients with EB have not been well described. METHODS: Retrospective study of BSI in children 0-18 years with EB from a national reference unit in Spain, in 2015-2020. RESULTS: Among 126 children with EB, we identified 37 BSI episodes in 15 patients (14 recessive dystrophic EB, 1 junctional EB). The most frequent microorganisms were Pseudomonas aeruginosa (n = 12) and Staphylococcus aureus (n = 11). Five P. aeruginosa isolates were ceftazidime-resistant (42%), 4 of which were also resistant to meropenem and quinolones (33%). As for S. aureus , 4 (36%) were methicillin-resistant and 3 (27%) clindamycin-resistant. In 25 (68%) BSI episodes skin cultures had been performed in the previous 2 months. The most frequent isolates were also P. aeruginosa (n = 15) and S. aureus (n = 11). In 13 cases (52%), smear and blood cultures grew the same microorganism, with the same antimicrobial resistance pattern in 9 isolates. Twelve patients (10%) died during follow-up (9 RDEB and 3 JEB). BSI was the cause of death in 1 case. In patients with severe RDEB, a history of BSI was associated with higher mortality (OR 6.1, 95% CI: 1.33-27.83, P = 0.0197). CONCLUSIONS: BSI is an important cause of morbidity in children with severe forms of EB. The most frequent microorganisms are P. aeruginosa and S. aureus , with high rates of antimicrobial resistance. Skin cultures can help guide treatment decisions in patients with EB and sepsis.

Diffuse leptomeningeal glioneuronal tumour: where to biopsy? Case report and literature review.

PURPOSE: Diffuse leptomeningeal glioneuronal tumour (DLGT) is an infrequent entity. Diagnosis is made with biopsy but with so few cases described management, prognosis remains undefined. There are not currently any articles regarding most effective place to biopsy. METHODS: Current literature review and introduction of the case of a 3-year-old male presenting at the emergency room with irritability, vomiting and nuchal rigidity. A head CT was made showing tetraventricular enlargement and a posterior fossa cyst. RESULTS: Patient underwent urgent ventriculoperitoneal shunting surgery with complete symptomp resolution. Brain MRI showed diffuse leptomeningeal enhancing, predominantly in basal cisterns, and multiple cystic-solid lesions along the neural axis. After ruling other conditions, a biopsy among intraoperative samples, was obtained of a PET positive gadolinium spinal enhancing lesion at D8 level, with the final diagnosis of DLGT. CONCLUSION: DLGT can present as acute hydrocephalus. Biopsy stablishes the diagnosis but the place to take the sample can be difficult to select. Our experience suggests that PET-CT and intraoperative biopsy analysis can improve the effectivity of a representative sample.

Staphylococcal toxic shock syndrome in a child with interleukin-17 inhibitor treatment for psoriasis.

A 6-year-old girl presented with fever, skin rash, anuria, and conjunctivitis that rapidly progressed to toxic shock syndrome. Following hospital discharge, she developed a staphylococcal abscess on the lower extremity. She had recently received the first two doses of the interleukin-17 (IL-17) inhibitor secukinumab for resistant plaque psoriasis. IL-17 is known to be essential in host defense against Staphylococcus aureus. To our knowledge, this is the first reported case of staphylococcal toxic shock syndrome (STSS) associated with an IL-17 inhibitor.

La versatilidad del adenovirus humano en el paciente inmunocompetente / The versatility of human adenovirus in the immunocompetent patient

Las infecciones por adenovirus humano se producen especialmente en niños menores de cinco años, se propagan fácilmente y, en algunos casos, son muy contagiosas. La mayoría de las infecciones son autolimitadas, de tipo respiratorio y gastrointestinal, y muchas veces son difíciles de diferenciar de las ocasionadas por otros virus. Excepcionalmente se confunden clínicamente con otros procesos, tal como ocurrió en los dos casos que presentamos. Sería deseable optimizar los métodos diagnósticos para abordar con más precisión estas infecciones y que nos permitan alejarnos de la incertidumbre

Human adenovirus infections occur especially in children under five years old, spread easily and, in some cases, are highly contagious. The majority of infections are self-limited, affecting the respiratory and gastrointestinal systems, and often are difficult to differentiate from those caused by other viruses. Occasionally they are confused in their clinical expression with other processes, as has happened in the two cases we present. It would be desirable to optimize the diagnostic methods in order to address these infections more accurately and to allow us to move away from uncertainty

Identifying priorities to improve paediatric in-hospital antimicrobial use by cross-sectional evaluation of prevalence and appropriateness of prescription / Detección de prioridades para mejorar el uso hospitalario de antimicrobianos en pediatría mediante la evaluación transversal de la prevalencia y adecuación de la prescripción

Introduction: Information about paediatric in-hospital antimicrobial usage and prescribing patterns to guide improvement strategies is scant. We aim to use an evaluation of the prevalence and appropriateness of antimicrobial prescription to identify antimicrobial stewardship priorities in children. Methods: A cross-sectional point study was performed on hospitalised paediatric patients in a Spanish tertiary hospital, assessing the prevalence of antimicrobial prescription (PAP) and appropriateness of antimicrobial prescription (AAP). AAP was defined as a correct indication plus an appropriate prescribing pattern (dose, spectrum and interval). Evaluation was performed using established antimicrobial guidelines. Other factors that may have a bearing on antimicrobial prescription were also analysed. Results: A total of 171 patients were included. PAP was 49.7% (85/171) and AAP was 60.9% (91/161). The most common indications for antimicrobial use were antimicrobial prophylaxis (28.3%, 32/113) and pneumonia (8.2%, 8/113). Overall, 161 antimicrobials were prescribed (1.9 antimicrobials per patient): 55.3% (89/161) were empiric, 16.1% (26/161) were targeted and 28.6% (46/161) were prophylactic. Amoxicillin/clavulanate (8.2%, 14/171) and sulfamethoxazole/trimethoprim (8.2%, 14/171) were the most prescribed antimicrobials. The prescription of antifungals (11.7%, 20/171) and antivirals (1.8%, 3/171) was analysed. Major causes of inappropriate antibiotic use were prolonged prescriptions (21.7%, 35/161) and use of agents with an excessively broad coverage spectrum (21.1%, 34/161). PAP and AAP varied between wards and antimicrobials. Conclusions: Measurement of PAP and AAP offers valuable information for detecting priorities in hospital settings and monitoring antimicrobial usage prior to the development of antimicrobial stewardship programmes. In our setting, the main areas for improvement are duration of therapy and proper use of broad-spectrum antimicrobials (AU)

Introducción: La información sobre el uso hospitalario de antimicrobianos en pediatría para orientar estrategias de mejora es escasa. Proponemos utilizar la evaluación de prevalencia y adecuación de la prescripción antimicrobiana para identificar prioridades en programas de optimización de uso de antimicrobianos en niños. Métodos: Se realizó un estudio de corte transversal en niños hospitalizados en un centro terciario español evaluando la prevalencia de prescripción antimicrobiana (PPA) y la proporción de adecuación en prescripción antimicrobiana (PAA). Se definió la PAA como una correcta indicación más un apropiado patrón de prescripción del antimicrobiano (dosis, espectro e intervalo) según guías establecidas. Se analizaron también otros factores con influencia potencial en prescripción. Resultados: Se incluyeron 171 pacientes, obteniendo una PPA=49,7% (85/171) y PAA=60,9% (91/161). Profilaxis antimicrobiana (28,3%, 32/113) y neumonía (8,2%, 8/113) fueron las indicaciones más frecuentes. Se realizaron 161 prescripciones antimicrobianas (1,9 antimicrobianos por paciente): 55,3% (89/161) empíricas; 16,1% (26/161) dirigidas y 28,6% (46/161) profilácticas. Amoxicilina/ácido clavulánico (8,2%, 14/171) y trimetoprim/sulfametoxazol (8,2%, 14/171) fueron los antimicrobianos más prescritos. Se analizó la prescripción antifúngica (11,7%, 20/171) y antiviral (1,8%, 3/171). Las principales causas de uso inapropiado de antibióticos fueron el uso prolongado (21,7%, 35/161) y espectros de cobertura demasiado amplios (21,1%, 34/161). La PPA y PAA variaron según área de hospitalización y antimicrobianos. Conclusiones: La PPA y PAA ofrecen información valiosa para detectar prioridades en hospitales previamente al desarrollo de programas de optimización de uso de antimicrobianos y monitorizar el uso de antimicrobianos. En nuestro centro la duración del tratamiento y el espectro antimicrobiano excesivo fueron las principales áreas a mejorar (AU)
