Inpatient hospital fatality related to coding (ICD-9-CM) of the influenza diagnosis in Spain (2009-2015).

BACKGROUND: To analyze hospitalization episodes with an ICD-9 diagnosis code of influenza (codes 487 and 488) in any diagnostic position from 2009 to 2015 in the Spanish hospital surveillance system. METHODS: Information about age, length of stay in hospital, mortality, comorbidity with an influenza diagnosis code between 1 October 2009 and 30 September 2015 was obtained from the National Surveillance System for Hospital Data (Conjunto Mínimo Básico de Datos, CMBD). RESULTS: 52,884 hospital admissions were obtained. A total of 24,527 admissions corresponded to diagnoses ICD-9 code 487 (46.4%), and 28,357 (53.6%) corresponded to ICD-9 code 488. The global hospitalization rates were 8.7 and 10.6 per 100,000 people, respectively. Differences between the two diagnostic groups were found for each of the six analyzed seasons. The diagnostic ICD-9-CM 488, male gender, and high-risk patients classified by risk vaccination groups showed direct relationship with inpatient hospital death. CONCLUSIONS: Influenza diagnosis was present in a significant number of hospital admissions. The code used for diagnosis (ICD-9-CM 488), male sex, age groups and associated risk clinical conditions showed a direct relationship with inpatient hospital fatality.

[Juvenile xanthogranuloma of the central nervous system]. / Xantogranuloma juvenil del sistema nervioso central.

INTRODUCTION: Juvenile xanthogranuloma (JXG) is a benign histiocytosis affecting mostly skin, although it may also be extracutaneous. Lesions tend to regress spontaneously, but there are cases of bad prognosis. CASE REPORT: We report the case of a girl aged 3 months with JXG involving skin and, asymptomatically, central nervous system (CNS) and lungs. At age 4 months, the bigger CNS lesion, placed in the right cavernous sinus and whose growth might have had important neurologic repercussions, was excised. After surgery she presented seizures with initial response to antiepileptic drugs. At age 8 and 10 months surgery was again necessary for appearance of a tension pseudoyst in postsurgical bed; a cystoperitoneal shunt was instaured and seizures were controlled. When the patient was 12 months old, the diagnosis of hypothyroidism was established, with a favourable response to levothyroxine. At present, the patient is 2 years 8 months and has a slightly slow neurologic development, with occasional short seizures. Skin lesion is smaller, lung nodules have regressed and, regarding CNS lesions, the bigger has not recurred and the other one remains stable. CONCLUSIONS: Some authors propose doing JXG s extension study only when suggested by clinical findings, so long as an effective therapy and the advantage to presymptomatic treatment are not well established. We wonder whether early diagnostic and therapeutic approach to silent deep lesions might lead to a better outcome of patients with JXG, particularly those with CNS involvement.
