ABSTRACT
Lyme disease (LD) is the most common tick-borne illness in Europe. Population-based studies in European children are few. This study aimed to assess the incidence, clinical presentation, treatment and outcome of serologically confirmed paediatric LD in the Republic of Ireland over a 5-year period. A retrospective review of records from accredited laboratories performing Borrelia burgdorferi serological testing was undertaken. Proformas were distributed to clinicians of children and adolescents with positive Lyme serology. Data were requested regarding clinical presentation, treatment and outcome. Updated NICE guidelines were used to classify clinical cases. Serology testing for B. burgdorferi was performed on 2908 samples. Sixty-three (2.2%) children were two-tier positive, generating a crude annual incidence rate of 1.15/100,000. Proformas were returned for 55 (87%) and 47 met clinical and laboratory criteria for LD. Twenty-seven (57%) presented with non-focal symptoms (erythema migrans and/or influenza-like symptoms), and 20 (43%) with focal symptoms (cranial nerve involvement, 11; CNS involvement, 8; arthritis, 1). Median age at presentation was 8.2 (2.5-17.9) years. Seventeen (36%) acquired LD overseas. Twenty-five (83%) of the remaining 30 children acquired infection in the West/Northwest of Ireland. Full resolution of symptoms was reported in 97% of those with available data. Serologically confirmed LD in children is relatively rare in the Republic of Ireland. Ninety-eight percent of children tested were seronegative. Of the seropositive cases, 40% could have been diagnosed based on clinical findings alone. Neurological presentations (40%) were common. Full resolution of symptoms occurred in almost all (97%) where data were available.

OBJECTIVE: This study aims to determine the prevalence of genital tract group B streptococcus (GBS) colonization in a cohort of pregnant Irish women and to compare patient preference and efficacy of self-collected versus health professional-collected swabs. STUDY DESIGN: In this prospective cohort study, 600 pregnant women attending public and private antenatal clinics at the Unified Maternity Services, Cork were included. At 35-37 weeks of pregnancy, these women self-collected an ano-vaginal swab and a health professional-collected a second swab on same clinic visit. The women filled a questionnaire to indicate their preferences. Statistical analysis was performed on SPSS Version 13. RESULT: The cumulative prevalence of maternal GBS colonization was 11.7% (95% CI, 9.3-14.6). The sensitivity of the self-collected swab was 84.3% (95% CI, 73.2-91.5) and that of health professional-collected swab was 94.3% (95% CI, 85.3-98.2). While good agreement in efficacy was found between health professional and patient-collected swabs (Kappa=0.87, p<0.001, 97.5% measure of concordance), only 28.5% women preferred self-collection, while 43.2% preferred a health professional to collect the swab and 28.3% had no preference. CONCLUSION: In our study the concordance between health professional and self-collected swab was excellent. However, pregnant women mainly prefer a health professional to collect their ano-vaginal swabs.

OBJECTIVES: In this study a large random collection (n = 378) of Irish thermophilic Campylobacter isolates were investigated for the presence of integrons, genetic elements associated with the dissemination of antimicrobial resistance. METHODS: Purified genomic DNA from each isolate was analysed by PCR for the presence of class 1 integrons. Four gene cassette-associated amplicons were completely characterized. RESULTS: Sixty-two of the isolates possessed a complete class 1 integron with a recombined gene cassette located within a 1.0 kb amplicon containing an aadA2 gene. This cassette was present in both Campylobacter jejuni and Campylobacter coli isolates and following sequence analysis was shown to be similar to sequences recently reported in Salmonella enterica Hadar and on an 85 kb plasmid conferring quinolone resistance in Escherichia coli. CONCLUSIONS: Aminoglycoside aadA2-encoding class 1 integrons were identified among unrelated Campylobacter spp. Amino acid sequence comparisons revealed identical structures in both Salmonella and E. coli. The presence of class 1 integrons in Campylobacter spp. may be significant should these organisms enter the food chain and especially when antimicrobial treatment for severe infections is being considered.
