Aim: Candida albicans (C. albicans) has been widely associated with the etiology of denture-related stomatitis and has been found on soft denture lining materials. The aim of this study was to examine the surface roughness and adherence of C. albicans to saliva coated and non-coated soft lining materials by subjecting s them to an in vitro accelerated aging test. o Methods and Materials: Samples were prepared from three soft lining materials (Visco Gel, Ufi Gel P, Molloplast B). Surface roughness measurements and adhesion of C. albicans were examined before and after s an aging process. The stimulated human whole saliva was used to assess its effect on adhesion. Results:The aging process promotes the surface roughness of soft lining materials. The aging surface roughness of Visco Gel was significantly higher than Ufi Gel P and Molloplast B. No significant difference was observed between non-aged and uncoated materials, but aged and uncoated soft lining materials showed a greater adherence of C. albicans. No significant difference was observed between non-aged and saliva coated materials, but aged and saliva coated soft lining materials showed a greater adherence of C. albicans. Conclusions:Candidosis induced by C. albicans is the most common fungal infection. Awareness of s susceptibility of soft lining materials to the adherence of C. albicans is an important factor in their selection. The use of soft lining materials with smooth surfaces minimizes the adherence of C. albicans.

IntroductionAcne is a very common skin disease in adolescents and young adults, but it also affects adults. However, its aetiology is not yet fully understood. Demodex appears to be associated with multiple skin disorders, but controversy persists. Some reports indicate a connection between acne vulgaris and demodicosis.AimTo confirm the association between Demodex infestation and acne vulgaris.Material and methodsA total of 108 patients were enrolled in the acne group. Acne severity was calculated as GASS and acne type (adolescent and post adolescent) was recorded. An age-sex matched healthy control group comprising 65 individuals were included in the study. Dermatological examinations were performed and an SSSB was used to determine the presence of Demodex.ResultsIn our study, Demodex positivity was seen in 46 (42.6%) patients in the acne group and 8 (12.3%) in the control group; this difference was statistically significant (p < 0.001). A multivariate Backward Step-By-Step Logistic Regression analysis identified the most effective factors for acne development such as Demodex positivity (OR = 5.565, 95% CI: 2.384–12.99 and p < 0.001) and age under 25 years (OR = 2.3 and 95% CI: 1.183–4.473 and p = 0.014). Alcohol consumption was related to Demodex positivity (p = 0.019) in post adolescent acne.ConclusionsOur study is the first one to evaluate acne severity, acne type and the relationship to Demodex prevalence. We suggest that Demodex infestation should be considered when the classical therapies are ineffective especially in cases of post adolescent acne.

The aim of this study was to determine the seroprevalence of toxocariasis in adult asthmatics and to assess its relationship with risk factors. A total of 124 asthmatic and 60 control group subjects were included in the study. Of the asthmatic patients, 61 (49.2%) were atopic and 63 non-atopic (50.8%). The anti-Toxocara IgG (Toxocara IgG CELISA Cellabs, Australia) positivity rate for all asthmatic cases was 9.7%. There was no significant difference between the asthmatic cases and the control group regarding anti-Toxocara IgG positivity (P>0.05). When risk factors were analyzed, there was a statistically significant difference between the control group subjects and patients with non-atopic asthma and also between the atopic asthmatic patients and the patients with non-atopic asthma regarding pets being under veterinary control (P<0.05). The percentages of those who had their pets defecate indoors were 0, 15 and 8.6%, respectively, for the control subjects, patients with non-atopic asthma and those with atopic asthma. There was a statistically significant difference when the control group subjects were compared to the patients with atopic asthma (P<0.05).
