Complement component C6 deficiency in a Spanish family: implications for clinical and molecular diagnosis.

Complement component C6 deficiency is a genetic disease presenting as increased susceptibility to invasive Neisseria meningitidis infections. This disorder has rarely been diagnosed in the Spanish population. In this work we report the immunochemical and molecular characterization of complement C6 deficiency in a Spanish patient showing no detectable functional activity of either the classical or alternative complement pathways and reporting a history of several episodes of meningococcal meningitis.

[Antibiotic prescription in acute respiratory infections in adults: its variability and appropriateness in 10 Spanish hospitals].

Objective: To report the variability in antibiotic prescribing habits for patients diagnosed of non-specified acute respiratory infections (ARI) (according to the International Classification of Diseases 9MC) at Emergency Departments of ten Spanish hospitals, and to evaluate the appropriateness of antimicrobial prescription for such patients, after specifically elaborating some reference patterns for appropriate antimicrobial use.

Design: Descriptive study of variability in clinical practice by means of a prospective series of cases. Study of appropriateness by means of elaborating reference standards for appropriate use and comparison with the data from the descriptive study with such standards.
