State and trait anxiety in women affected by allergic and vasomotor rhinitis.

It is still debatable whether anxiety and depression in patients affected by rhinitis could play a role in the genesis of the disease, whether they are a consequence of the symptoms. The aim of this study was to evaluate anxiety levels in both state and trait forms, and depression, in patients affected by allergic (AR) and vasomotor rhinitis (VMR). A total of 45 women, 24 AR and 21 VMR were compared with 64 healthy nonallergic women matched for age and sociodemographic characteristics. All subjects were administered the State and Trait Anxiety Inventory (STAI) and the Zung self-rating depression scale. The percentage of subjects with high levels of state anxiety was significantly higher in AR (p<0.005) and VMR (p<0.01) with respect to controls. The percentage of subjects with high levels of trait anxiety was significantly higher in AR (p<0.001) and VMR (p<0.05) than controls. There was no significant difference in depression between AR and VMR and controls. No significant difference was found in state anxiety, trait anxiety, or depression between AR and VMR. In conclusion, anxiety in patients with rhinitis is present both as a state and as a trait, at least when measured with the STAI.

Probiotic treatment increases salivary counts of lactobacilli: a double-blind, randomized, controlled study.

BACKGROUND/AIMS: Lactobacilli are used in the prevention and treatment of several diseases, but they are also known to play a role in the pathogenesis of dental caries. The aim of our study was to evaluate whether the oral administration of lactobacilli could change the salivary counts of these bacteria compared with placebo. Moreover, lactobacilli were administered in liquid and in capsule form to determine the role of direct contact with the oral cavity. METHODS: Thirty-five healthy volunteers were randomized into three groups to receive lactobacilli and/or placebo for 45 days: group A (n = 14) received probiotics in capsules and placebo in liquid form; group B (n = 16) took liquid probiotics and placebo in capsules, and group C (n = 5) used placebo in both liquid and capsule form. Streptococcus mutans populations served as control. The salivary counts of lactobacilli and S. mutans were measured semi-quantitatively using the CRT bacteria kit. RESULTS: Compared with placebo, the oral administration of probiotics, both in capsules and in liquid form, significantly increases salivary counts of lactobacilli (p = 0.005 and p = 0.02, respectively). S. mutans populations were not significantly modified. CONCLUSIONS: The increased salivary counts of lactobacilli may indicate the need to closely monitor the dental health of patients undergoing long-term probiotics treatment, even when this treatment is administrated in a form that avoids direct contact with the oral cavity.
