Background: Herpes zoster is an important problem of public health especially among the elderly in Spain.
Methods: A population-based retrospective epidemiological study to estimate the burden of herpes zoster requiring hospitalization in the Canary Islands, Spain was conducted by using data from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos. Records of all patients admitted to hospital with a diagnosis of herpes zoster in any position and cases of primary diagnosis (ICD-9-MC codes 053.
Background: Mortality from invasive meningococcal disease (IMD) has remained stable over the last thirty years and it is unclear whether pre-hospital antibiotherapy actually produces a decrease in this mortality. Our aim was to examine whether pre-hospital oral antibiotherapy reduces mortality from IMD, adjusting for indication bias.
Methods: A retrospective analysis was made of clinical reports of all patients (n = 848) diagnosed with IMD from 1995 to 2000 in Andalusia and the Canary Islands, Spain, and of the relationship between the use of pre-hospital oral antibiotherapy and mortality.
Background: Meningococcal Disease is mainly monitored passively on the Canary Islands, the regular Compulsory Disease Notification channels being used. The objective of this study includes describing the qualitative and quantitative aspects of this system and evaluating the exhaustiveness, by means of the capture-recapture system, of three information sources.
Methods: This study covers the 1999-2001 period in Tenerife.
