[Tuberous sclerosis complex: analysis of areas of involvement, treatment progress and translation to routine clinical practice in a cohort of paediatric patients]. / Complejo esclerosis tuberosa: análisis de los ámbitos de afectación, progreso en el tratamiento y traslación a la práctica clínica habitual en una cohorte de pacientes pediátricos.

INTRODUCTION: Tuberous sclerosis complex (TSC) displays great phenotypic variability. Increasingly early diagnosis, including prenatal identification, entails the need for the paediatrician and neuropaediatrician to establish early suspicion and identification of factors that may influence prognosis and treatment. AIM: To determine the clinical criteria for early diagnosis, initial complementary tests, actions and treatments to prevent different comorbidities, so as to improve the prognosis of these patients. PATIENTS AND METHODS: Descriptive, retrospective study of = 18-year-olds with a definitive diagnosis of TSC in a tertiary hospital from 1998 to 2019. We collected variables referring to epidemiological data, multisystem involvement, complementary tests and genetics. RESULTS: Ninety-four patients were analysed. The main diagnostic reasons were epilepsy and rhabdomyomas. The frequency of occurrence of clinical criteria was determined, and neuropathological findings were the main findings, followed by cutaneous stigmata, rhabdomyomas and renal lesions. Statistical relationships were found between clinical, radiological and genetic aspects, the influence of preventive activities on the occurrence of epilepsy and the relevance of everolimus use were tested. CONCLUSIONS: Rhabdomyomas and skin stigmata in patients and parents are major diagnostic signs in infants. Tubers and subependymal nodules are statistically associated with the development of epilepsy. Early epileptic spasms, refractory to treatment in the first months, increase the risk of cognitive deficits and autism spectrum disorder. Epileptic abnormalities need to be closely monitored in the first year of life. Everolimus is an alternative treatment for several comorbidities, but its early use (< 3 years) requires further study.

TITLE: Complejo esclerosis tuberosa: análisis de los ámbitos de afectación, progreso en el tratamiento y traslación a la práctica clínica habitual en una cohorte de pacientes pediátricos.Introducción. El complejo esclerosis tuberosa (CET) presenta gran variabilidad fenotípica. El diagnóstico cada vez más precoz, incluyendo la identificación prenatal, conlleva la necesidad de establecer una sospecha e identificación temprana, por parte del pediatra y del neuropediatra, de factores que pueden influir en su pronóstico y tratamiento. Objetivo. Determinar los criterios clínicos de un diagnóstico precoz, las pruebas complementarias iniciales, las actuaciones y los tratamientos que prevengan diferentes comorbilidades, mejorando el pronóstico de estos pacientes. Pacientes y métodos. Estudio descriptivo, retrospectivo de = 18 años con diagnóstico definitivo de CET en un hospital terciario desde 1998 hasta 2019. Se recogieron variables epidemiológicas, de afectación multisistémica, pruebas complementarias y genética. Resultados. Se analizó a 94 pacientes. Los principales motivos diagnósticos fueron la epilepsia y los rabdomiomas. Se determinó la frecuencia de aparición de los criterios clínicos, y los hallazgos neuropatológicos fueron los principales, seguidos de los estigmas cutáneos, los rabdomiomas y las lesiones renales. Se comprobaron relaciones estadísticas entre aspectos clínicos, radiológicos, genéticos, la influencia de las actividades preventivas sobre la aparición de epilepsia y la relevancia del uso de everolimús. Conclusiones. Los rabdomiomas y los estigmas cutáneos en pacientes y progenitores constituyen signos diagnósticos principales en lactantes. Los túberes y los nódulos subependimarios tienen asociación estadística con el desarrollo de epilepsia. Los espasmos epilépticos en edades precoces, refractarios a tratamiento en los primeros meses, incrementan el riesgo de déficit cognitivo y trastorno del espectro autista. Es necesario monitorizar estrechamente las anomalías epilépticas en el primer año de vida. El everolimús supone una alternativa de tratamiento en varias comorbilidades, pero su uso precoz (menor de 3 años) precisa más estudios.

Cyclosporine A for severe atopic dermatitis in children. efficacy and safety in a retrospective study of 63 patients.

BACKGROUND: Cyclosporine A (CSA) is an immunosuppressant agent widely used in severe atopic dermatitis (AD). However, experience in children is limited. OBJECTIVES: To assess the efficacy and adverse events of CSA therapy in children. METHODS: Retrospective study of children with severe AD treated with CSA between January 2009 and December 2015. RESULTS: Data from 63 patients were collected. Mean age at the beginning of treatment was 8.4 years (±3.6). The median starting dose was 4.27 (±0.61) mg/kg/day. After 4 weeks of treatment, the outcome was excellent in 35% of cases, good in 29% and poor in 36% of the patients. The response was better in patients without eosinophilia (P < 0.05). The median duration of treatment was 4.6 months (range 1.5-21.6). Side-effects were frequent but mild, being more common in patients after longer treatment periods (P < 0.05). Mean time of follow-up was 19.4 months (±12.7). Prolonged remission (>6 months) was observed in 13 patients (20%). LIMITS: This is a retrospective review. The follow-up period is limited. CONCLUSIONS: Our data confirm that CSA is efficacious and acts rapidly in the majority of children with severe AD. CSA therapy can provide sustained remission in some patients. CSA seems to be well tolerated in children, but strict monitoring is mandatory.

[Urinary tract infections: antibiotic resistance and clinical follow up]. / Infecciones del tracto urinario: sensibilidad antimicrobiana y seguimiento clínico.

The initial treatment of the urinary tract infections (UTI) is empirical and it is a priority to determine the antibiotic resistance of most common germs in a population. Furthermore, due to the suspicion of acute pyelonephritis the presence of renal scarring should be ruled out as this may lead to further complications. A retrospective longitudinal study was performed on all children under 14 years diagnosed with UTI from January 1 2009 to December 31 2009. The in vitro susceptibility to the most important urinary pathogens was analysed, along with the presence of scars, and a subsequent follow-up. The most frequently isolated bacteria were E. coli (80%), P. mirabilis (9.7%) and K. pneumoniae (4.2%). In the antibiogram, E coli showed a high sensitivity to fosfomycin (99.1%), cefotaxime (98.2%) cefuroxime (97.3%) and gentamicin (95.6%). The sensitivity obtained against amoxicillin-clavulanate was 83.2%, while that obtained against cotrimoxazole was 78.9%. Post-pyelonephritis scars were found in 19% of patients with febrile UTI, 17% out-patients and 20% of those admitted.
