Pediatric septic thrombosis of intracranial venous sinuses: from diagnosis to discharge. Twenty years of experience. / Trombosis séptica pediátrica de senos venosos intracraneales: del diagnóstico al alta. Veinte años de experiencia.

INTRODUCTION: Septic thrombosis of intracranial venous sinuses (STSV) is a rare and severe complication of cranial infections. MATERIALS AND METHODS: The main objective of this paper is to describe the clinical data, diagnostic procedures, treatment and evolution of a series of cases of STSV. In addition, the current literature is reviewed. Observational retrospective study by review of medical histories (January 1995-December 2016). The data collected were: clinical, analytical, epidemiological, microbiological, radiological, management and follow-up. A descriptive and statistical analysis of the data was done. RESULTS: Twelve children were included (86,832 admissions studied). They have a median age of 4.5 years (range 1-13) with a median time of symptoms of 6 days (range 1-25). At admission, the clinical data were: fever (11/12), vomiting (9/12) and headache (8/12). They also showed bad general status 12/12, 7/12 acute otitis media and 5/12 VI cranial nerve paresis. The lumbar puncture was pathological in 4/12. The most frequently microorganism isolated was Streptococcus sp. Prothrombotic mutations were confirmed on 2/12. Cranial computed tomography allowed diagnosis in 9/12; the magnetic resonance imaging achieves that in 12/12. Previous neurological signs or time to diagnosis did not influence the appearance of other image complications. All received antibiotic treatment, heparin 10/12 and 11/12 surgery. There were no sequels. CONCLUSION: In our series otitis, headache, vomiting and fever were prevalent. Complementary tests allowed the suspect but the definitive diagnosis was obtained by neuroimaging. There were no sequels and the therapies were mainly wide broad-spectrum antibiotics, heparin, and surgical.

TITLE: Trombosis séptica pediátrica de senos venosos intracraneales: del diagnóstico al alta. Veinte años de experiencia.Introducción. La trombosis séptica de los senos venosos intracraneales (TSSV) es una complicación rara y grave de las infecciones craneales. Materiales y métodos. El objetivo principal de este trabajo es describir los datos clínicos, procedimientos diagnósticos, tratamiento y evolución de una serie de casos de TSSV. Además, se revisa la bibliografía actual. Es un estudio retrospectivo observacional mediante revisión de historias médicas (enero de 1995-diciembre de 2016). Los datos recogidos fueron: clínicos, analíticos, epidemiológicos, microbiológicos, radiológicos, de manejo y de seguimiento. Se realizó un análisis descriptivo y estadístico de los datos. Resultados. Se incluyó a 12 niños (86.832 ingresos estudiados). La mediana de edad fue de 4,5 años (rango: 1-13), con un tiempo medio de síntomas de 6 días (rango: 1-25). En el momento de la admisión, los datos clínicos fueron: fiebre (11/12), vómitos (9/12) y dolor de cabeza (8/12). También mostraron mal estado general, 12/12; otitis media aguda, 7/12; y paresia del VI par craneal, 5/12. La punción lumbar fue patológica en 4/12. El microorganismo más frecuentemente aislado fue Streptococcus spp. Se confirmaron mutaciones protrombóticas en 2/12. La tomografía computarizada craneal permitió el diagnóstico en 9/12; la resonancia magnética lo logró en 12/12. Los signos neurológicos anteriores o el tiempo de diagnóstico no influyeron en la aparición de otras complicaciones de la imagen. Recibieron tratamiento antibiótico 12/12; heparina, 10/12; y cirugía, 11/12. No hubo secuelas. Conclusión. En nuestra serie, la otitis, el dolor de cabeza, los vómitos y la fiebre fueron frecuentes. Las pruebas complementarias permitieron el diagnóstico de sospecha, pero el diagnóstico definitivo se obtuvo por neuroimagen. No hubo secuelas y las terapias fueron principalmente antibióticos de amplio espectro, heparina y cirugía.

Respiratory and pharmacological management in severe acute bronchiolitis: Were clinical guidelines not written for critical care?

PURPOSE: The treatment applied for children admitted to the pediatric intensive care unit (PICU) for severe acute bronchiolitis may differ from general recommendations. The first objective of our study was to describe the treatments offered to these children in a Spanish tertiary PICU. The second objective was to analyse the changes in management derived from the publication of the American Academy of Pediatrics (AAP) bronchiolitis guideline in 2014. METHODS: This was a retrospective-prospective observational study conducted during two epidemic waves (2014-2015 and 2015-2016). The AAP guidelines were distributed and taught to PICU staff between both epidemic waves. RESULTS: A total of 138 children were enrolled (78 male). In the first period, 78 children were enrolled. The median age was 1.8 months (IQR 1.1-3.6). There were no differences between the management in the two periods, except for the use of high-flow oxygen therapy (HFOT); its use increased in the second period. Overall, 83% of patients received non-invasive ventilation or HFOT. Children older than 12 months received HFOT exclusively. In comparison, continuous positive airway pressure and bi-level positive airway pressure were used less during the period 2015-2016 (P=0.036). Regarding pharmacological therapy, 70% of patients received antibiotics, 23% steroids, 33% salbutamol, 31% adrenaline, and 7% hypertonic saline. The mortality rate was zero. CONCLUSIONS: Our PICU did not follow the AAP recommendations. There were no differences between the two periods, except in the use of HFOT. All children older than 12 months received HFOT exclusively. The rate of using invasive mechanical ventilation was also low.

[Extreme reactive thrombocytosis in a healthy 6 year-old child]. / Trombocitosis extrema reactiva en un niño sano de 6 años.

Thrombocytosis is usually a casual finding in children. Reactive or secondary thrombocytosis is the more common form, being the infections diseases the most prevalent cause of it. Regarding the number of platelets there are four degrees of thrombocytosis; in its extreme degree the number of platelets exceeds 1,000,000/mm(3). We describe a case of extreme reactive thrombocytosis in a healthy 6-year-old child. He required critical care admission for diagnosis and treatment (maximum number of platelets 7,283,000/mm(3)). We review the different causes of thrombocytosis in childhood, the differential diagnosis, and the available treatments in case of extreme thrombocytosis.

Extreme reactive thrombocytosis in a healthy 6 year-old child.

Thrombocytosis is usually found by chance in children. Reactive or secondary thrombocytosis is the more common form, with infectious diseases being the most prevalent cause of it. Regarding the number of platelets there are four degrees of thrombocytosis; in its extreme degree the number of platelets exceeds 1,000,000/mm3. We describe a case of extreme reactive thrombocytosis in a healthy 6-year-old child. He required critical care admission for diagnosis and treatment (maximum number of platelets 7,283,000/mm3). We review the different causes of thrombocytosis in childhood, the differential diagnosis, and the available treatments in case of extreme thrombocytosis.

La trombocitosis es un hallazgo casual frecuente en pediatría. En niños, predominan las formas secundarias, siendo las infecciones su causa más prevalente. Se distinguen 4 grados de trombocitosis en función del número de plaquetas; en la forma extrema, se supera el 1.000.000/mm3. Se presenta un caso de trombocitosis extrema reactiva en un niño sano de 6 años, que requirió ingreso en cuidados intensivos para tratamiento y diagnóstico (cifra máxima de plaquetas de 7.283.000/mm3). Se revisan las diferentes causas de trombocitosis en la infancia, se describe el diagnóstico diferencial y se discute sobre los diferentes tratamientos disponibles ante un caso como el descrito.
