Variables related to chronic immune thrombocytopenia: experience from a single center and comparison to a meta-analysis.

Classically, several variables have been related to the disease course of chronic primary immune thrombocytopenia (cITP), though to date, there is no consensus on their clinical relevance. In a recent systematic review, a meta-analysis was made and confirmed the existence of certain cITP-related variables that may be related to prognosis in pediatric patients. We retrospectively analyzed a cohort of patients diagnosed with ITP, identified prognostic variables, and compared our results to the variables described by the authors. A multivariate study revealed that older age at diagnosis and higher platelet count were the only independent variables related to cITP. Children up to age 4 years and those with lower platelet counts (below 20 × 109/L) were at lower risk for cITP.Conclusion: We therefore concluded that only age and platelet count at diagnosis are independent variables that should be considered when evaluating the risk of developing cITP. What is Known: • Around 20% of patients with immune thrombocytopenia progress to chronic disease as determined by a sustained platelet count below 100×109/L for more than 12 months. • A number of variables potentially related to the development of cITP are being studied, such as age, sex, cell count, and previous treatment. What is New: • This is a new group of patients diagnosed with ITP in which the platelet count and age at diagnosis are the only independent variables closely related to cITP. • In this new series, we could not confirm other variables previously related to cITP such as total leukocyte count or the absence of treatment at diagnosis.

Comparison of abnormal cell flagging of the hematology analyzers Sysmex XN and Sysmex XE-5000 in oncohematologic patients.

INTRODUCTION: Hematology analyzers should optimize flagging while minimizing false-negative results and unnecessary microscopic reviews. METHODS: We compared flagging performance of Sysmex XE-5000 and XN analyzers in oncohematologic patients. Differential counts were performed by Cellavision digital system (100 cells) and a hematologist (another 100 cells). RESULTS: First, we included 292 samples (86 with blasts): 28 acute lymphoblastic leukemia, 88 acute myeloid leukemia, 91 myelodysplastic syndromes, 45 chronic myeloproliferative neoplasms, and 40 chronic myelomonocytic leukemia. Sensitivity, specificity and efficiency to detect blasts were 59.3%, 88.3%, and 79.8% for XE-5000 analyzer and 70.9%, 91.3%, and 85.2% for the XN analyzer. Then, we included 111 lymphoid malignancies. In 55 CLL XE-5000 flagged for Abn Lympho/L_Blasts?, XN flagged for Abn Lympho?. In one-third of 19 samples with splenic marginal lymphoma, none of the analyzers flagged. In 5 Sézary syndrome cases, XE-5000 triggered the Abn Lympho/L_Blasts? flag while the flagging in XN was less consistent: Abn Lympho? Blasts? and Atypical Lympho?. In 5 hairy cell leukemias, both analyzers only flagged one sample. In 13 myelomas, XE-5000 generated Atypical Lympho? flag; XN triggered more variable flags. In other lymphoid malignancies, flags were variable. XN analyzer generates less samples with false basophilia. CONCLUSION: XN analyzer has improved blast detection in oncohematologic patients. Operators cannot rely on the blast flag alone but have to consider other flags and hemogram data. In lymphoproliferative disorders, XN analyzer yields less samples with pseudobasophilia. Both analyzers must improve flagging for hairy cell leukemia.

[Guidelines for cochlear implant indication in Navarre]. / Guía clínica para la indicación de implantes cocleares en la Comunidad Foral de Navarra.

Cochlear implants are indicated in severe to profound hearing loss with no benefit with hearing aids. Since the beginning of cochlear implants 30 years ago, auditory outcomes have been improving due to changes introduced in differ-ent areas: electrode design, strategy, surgical technique... Given good results within this period of time, cochlear implant indication has varied too. The aim of this paper is to show an update on indication criteria for cochlear implantation in Navarre, for application in daily practice. The indications are established by consensus amongst the hospitals of the region.

Guía clínica para la indicación de implantes cocleares en la Comunidad Foral de Navarra / Guidelines for cochlear implant indication in Navarre

La colocación de un implante coclear es una medida útil para paliar la hipoacusia neurosensorial de grado severo-profundo en aquellos casos en los que el beneficio del audífono es escaso. Desde su inicio hace 30 años los resultados auditivos han mejorado gracias a los progresivas mejoras que se han adoptado en distintos ámbitos: su diseño, estrategia, técnica quirúrgica... Dados los buenos resultados en este periodo, las indicaciones también han variado. El objetivo de este trabajo es revisar los criterios establecidos y emergentes de indicación de implante coclear, estableciendo de manera consensuada, entre los centros sanitarios de la Comunidad Foral de Navarra, unos criterios actualizados para la indicación del mismo en dicha área territorial, de forma que pueden servir de referencia en situaciones clínicas diferenciadas (AU)

Hipoacusias en la edad infantil. Diagnóstico y tratamiento / Hypoacusis during childhood. Diagnosis and treatment

En la práctica pediátrica la valoración de la audición constituye una actividad importante. Permite confirmar con diferentes técnicas si el niño oye bien o no, hecho que se puede sospechar a través de otras fuentes (familia, escuela).Es por ello fundamental que se sepa valorar adecuadamente porque incidirá de manera importante en el desarrollo del niño. Así, una hipoacusia puede ser causa de una inadaptación o fracaso escolar según la edad, o de alteraciones del lenguaje. Se describen los diferentes tipos de hipoacusia y sus técnicas para el diagnóstico y correspondiente tratamiento. Se hace una reflexión sobre el problema de la otitis media serosa en Atención Primaria y su derivación a la unidad de ORL infantil (AU)
