    Background/aim: Chitotriosidase (ChT) is an enzyme secreted by activated macrophages and neutrophils in response to proinflammatory signals. There is growing evidence indicating that ChT activity reflects the systemic inflammatory status. This study aimed to investigate whether serum ChT activity increased in patients with psoriasis and related comorbidities. Materials and methods: This cross-sectional study included 53 (28 with associated comorbidities and 25 without comorbidities) patients with psoriasis and 52 healthy volunteers. All participants underwent laboratory investigations for serum ChT levels, complete blood count, erythrocyte sedimentation rate, C-reactive protein, and serum lipid levels. Results: The patients with psoriasis showed significantly higher levels of ChT activity as compared to the healthy controls (23.5 +/- 11.4 vs. 17.5 +/- 10.4 mu mol/mL/hour; p = 0.015). Additionally, the ChT activity was significantly higher in patients with comorbidities than in those without (p = 0.042). Conclusion: Our data support the pathogenetic role of inflammatory processes induced by macrophage activation in patients with psoriasis and related comorbidities. We believe that high ChT activity in patients with psoriasis may serve as an early prediction of the possible related comorbidities.

    Relationship between rosacea and chronic obstructive pulmonary disease Rosacea and comorbidities
    (Wiley, 2022) Demirbaş, Abdullah; Yümer, Yusuf; Elmas, Ömer Faruk; Ulutaş Demirbaş, Gözde; Atasoy, Mustafa; Tursen, Ümit; Dursun, Recep
    Background Rosacea is a chronic inflammatory skin disease that has been reported to be associated with many systemic disorders including respiratory diseases. Aims This study aims to investigate respiratory function in patients with rosacea. Patients/Methods Patients with rosacea and age- and gender-matched healthy volunteers were included in this cross-sectional study. Spirometric pulmonary function tests including the percentage of forced vital capacity (FVC%), percentage of forced expiratory volume in one second (FEV 1%), forced expiratory flow at 25-75% of FVC (FEF 25-75%), and FEV 1/FVC ratio was assessed in both patient and controls. The potential relationship between rosacea severity and pulmonary functions was assessed. Results A total of 120 patients with rosacea and 120 healthy controls were enrolled in the study. Compared to the controls, FEV 1%, FEV 1/FVC%, and FEF 25-75% values were significantly lower in patients with rosacea. Lower FEV 1/FVC% values were found to be associated with disease severity. FEV 1%, FEV 1/FVC%, and FEF 25-75% values were found to be more useful in differentiating the patients from healthy subjects. Conclusions This study showed that patients with rosacea may have abnormal respiratory function compared to healthy subjects. Besides, disease severity was associated with worse respiratory functions. We believe that patients with rosacea, particularly those with additional risk factors, should be screened for respiratory disorders.

    Therapeutic efficacy and safety of three different modalities in pediatric patients with plantar warts
    (Wiley, 2021) Acar, Emine Müge; Uyar, Belkiz; Elmas, Ömer Faruk; Özyurt, Kemal; Atasoy, Mustafa; Tursen, Ümit; Lotti, Torello
    Human papillomavirus infection is relatively common in communities. Thus, determining an effective and painless treatment method, especially in pediatric patients is of utmost importance. This study aimed to compare the outcomes of three different methods of treating plantar warts in pediatric patients. Children with verruca plantaris treated with a salicylic acid-lactic acid combination once daily (SA/LA 1), a salicylic acid-lactic acid combination applied in three to seven layers under occlusion every 3 days (SA/LA 2), or a combination of 5-fluorouracil (0.5%) and salicylic acid (10%) (SA/5-FU) were evaluated retrospectively. Treatment responses and recurrence rates were also evaluated after a minimum of 4 months. Among the 98 children with verruca plantaris, 19 were treated with SA/LA 1, 53 were treated with SA/LA 2, and 18 were treated with SA/5-FU; the eight patients who received cryotherapy were excluded. The mean treatment duration was significantly shorter in the SA/LA 2 group than in the SA/LA 1 group and the SA/5-FU group. (p = 0.000 for both) Application of a salicylic acid-lactic acid combination in multiple layers under occlusion is a safe, painless, and effective treatment method for plantar warts in children.
