Prenatal antibiotic exposure increases the risk of infant atopic dermatitis: data from a Greek cohort.

Summary: Background. The human microbiome is important due to the impact it has on host immunologic development and allergy-associated diseases. This study aimed to investigate the impact of prenatal exposure to antibiotics on the incidence of atopic dermatitis (AD) in children at 18 months of age. Methods. Mothers were interviewed at baseline, in the maternity ward and by phone questionnaire after 18 months. Demographic data, mode of delivery, yoghurt consumption, antibiotic and other drug use during pregnancy, atopic history, diagnosis of AD and history of infections in the offspring were noted. Results. 385 mothers were interviewed at baseline. 231 (60%) mothers with 236 children responded at follow up. Cesarean section was reported in 116 (50.2%) deliveries while antibiotic use during pregnancy in 55/231 (23.8%) women. 43/236 (18.22%) infants were diagnosed with AD. Intravenous antibiotic use was associated with a 7.7 increased risk of AD diagnosis in the offspring (95%CI 1.23-48.27, p = 0.029). An increased odd for AD was recorded for mothers 30-40 years of age (OR 4.50, 95%CI 1.08-18.7, p = 0.039). No significant association between cesarean section and AD (p = 0.70) was recorded. In multivariate analysis, reported food allergy (OR 8.03, 95%CI 2.30-27.97, p = 0.001) and otitis media episodes in children (OR 3.76, 95%CI 1.60-8.83, p = 0.002) were significantly associated with AD diagnosis. Conclusions. An increased risk of AD was recorded only when antibiotics were given prenatally by intravenous route and in women between 30-40 years of age. Children with food allergy had an increased risk for AD. The relatively high percentage of cesarean sections was not a risk factor for AD.

Chorea revealing systemic lupus erythematosus in a 13-year old boy: A case report and short review of the literature.

Among the neurological manifestations of systemic lupus erythematosus (SLE), chorea is rare, presenting in less than 7% of the pediatric SLE patients. It can appear early in the onset of SLE, be the first or even the sole clinical feature of the illness and has strongly been associated with the presence of antiphospholipid antibodies. We report on the case of a 13-year old boy, admitted with acute onset chorea and finally diagnosed with SLE. Subsequently, we present a short review of the literature on the epidemiology, suggested pathogenesis, clinical presentation and treatment of this rare presentation of SLE.

Stress management and erectile dysfunction: a pilot comparative study.

Erectile dysfunction (ED) is a complex disorder with various biopsychosocial implications leading the individual into a state of chronic stress that further worsens ED symptoms. The aim of this study is to investigate the effects of a 8-week stress management programme on erectile dysfunction (ED). A convenience sample of 31 newly diagnosed men with ED, aged between 20 and 55 years, was recruited during a period of 5 months to receive either tadalafil (12 patients) or tadalafil and the 8-week stress management programme. Both groups showed statistical significant improvement of both perceived stress and erectile function scores. Men practising stress management showed a statistical significant reduction in perceived stress score compared with men receiving tadalafil alone. No other statistical significant differences were noted between the two groups, although the stress management group showed a lower daily exposure to cortisol compared with the control group after 8 weeks. Finally, perceived stress and cortisol showed some interesting correlations with sexual function measurements. These findings provide important insight into the role of stress management, as part of the recommended biopsychosocial approach, in ED. Future studies should focus on randomised, controlled trials with larger samples and longer follow-up time.
