Comparison of phenotypic and genotypic markers for characterization of an outbreak of Salmonella serotype Havana in captive raptors.

AIMS: To establish a typing method for tracing the epidemic relationship of 16 strains of Salmonella serotype Havana isolated from captive raptors showing no symptomatology and residing in a wildlife hospital in Spain. METHODS AND RESULTS: Antimicrobial susceptibility testing, ribotyping, pulsed field gel electrophoresis (PFGE) and amplified fragment length polymorphism (AFLP) methodology were applied. Ten unrelated strains of serotype Havana were included as a control group to provide a basis of for the efficiency of the different markers used. All outbreak-related strains were resistant to nalidixic acid and streptomycin and showed the same ripotype, pulsotype and AFLP pattern. CONCLUSIONS: This is the first time that AFLP analysis has been tested with serotype Havana isolates and it has demonstrated to be the most useful epidemiological tool for discriminating between unrelated and outbreak-related strains of this serotype. The results obtained suggest that all the Salmonella serotype Havana isolates represented a common outbreak strain whose origin of contamination could not be established although it is thought that it was the poultry meat used for raptors'diet. SIGNIFICANCE AND IMPACT OF THE STUDY: Our study suggests the importance of microbiological analysis of these products in order to prevent contamination and dissemination of Salmonellae in this kind of Hospital.

Prevalence of epilepsy in northeast Madrid.

During a period of 42 months, we studied the prevalence of epilepsy in a specific health district, composing by four towns with 98,405 inhabitants older than 10 years. This has been accomplished by a two-phase cross-sectional study. The prevalence rate observed was 4.12/1000 inhabitants for all types of epilepsy. No significant differences were found between the sexes. Sixty-three per cent of affected individuals had partial seizures, with a confirmed cause in 45%. Fifty-five patients with single unprovoked seizures, were also identified but not included in the prevalence rate.

[Relationship between primary care and neurological care].

The problems posed by health care are related to health service structure and development. The transformation of a three level care structure into one of just two levels, primary care and specialized care, plays its part. With the aim of analyzing the importance these factors might have in present-day health care, we carried out an aleatoric study of all those patients who attended our neurological service in the years 1992 and 1993. We obtained two sample groups consisting of 921 and 849 patients respectively through interconsultatory requests from practitioners within a limited health care area. We studied the patient's background, the requesting practitioner, diagnosis obtained and complementary tests used. Patients from individual practitioners varied in number from 4 to 38, with some 20% of all patients having been referred by just six practitioners. 20% of the patients we studied showed no neurological pathology. Complementary tests used in all diagnoses sent to us amounted to less than half the number of patients studied. We analyzed the importance these factors have in the present delay in health care services.

[Upward and downward gaze palsy with a unilateral mesencephalic hemorrhage].

INTRODUCTION: Acute vascular lesions limited to the midbrain can yield varied disturbances of eye movements. They are more often infarcts than hemorrhages. CLINICAL CASE: We present the case of a 49 year old, non-hypertensive man who presented with sudden onset of bilateral up and down gaze palsy. CT defined a unilateral hemorrhage in the right mesencephalic tegmentum. CONCLUSION: Cases of upward and downward gaze palsy in association with unilateral upper midbrain hemorrhage are very uncommon. We present a new case.
