Investigating the effect of the aroma inhalation of orange and lavender essential oils in comparison with placebo on the level of anxiety in clients in a dental clinic in Shiraz: A double-blind controlled randomized clinical trial

Background: Attending a dentist and placing on the unit can cause anxiety. Objective: The aim of this study was to compare the effect of the aroma inhalation of orange and lavender essential oils in comparison with placebo on the level of anxiety in clients in a dental clinic in Shiraz. Methods: This randomized double-blind clinical trial was performed on 120 patients referred to a Dental Clinic. The patients were divided into three groups of anxiety treatments with scent of lavender, orange and sesame (as control). The Spielberger questionnaire was used to measure the anxiety of the patients before and after the study. Data were analyzed by SPSS version 22. The level of significance was considered as 5%. Results: Overall, there is no difference in the state scores of anxiety before and after the interventions. In the sesame group (ttest (-0.068) and the significant level (0.501), in the orange group (t (0.465) and significant level (0.645), in the lavender group (t (0.321) and significant level (0.750). However, a statistically significant difference was observed between the levels of state and trait anxiety after the interventions in all three groups. Conclusion: Although, based on the present study, the use of orange and lavender extracts had partially reduced the levels of state and trait of anxiety in dental clients, more clinical studies are recommende

A Note on Exact Solutions and Attractor Mechanism for Non-BPS Black Holes

We obtain two extremal, spherically symmetric, non-BPS black hole solutions to 4D supergravity, one of which carries D2-D6 charges and the other carries D0-D2-D4 charges. For the D2-D6 case, rather than solving the equations of motion directly, we assume the form of the solution and then find that the assumption satisfies the equations of motion and the constraint. Our D2-D6 solution is manifestly dual to the solution presented in 0710.4967. The D0-D2-D4 solution is obtained by performing certain $[SL(2,{\bf Z})]^{3}$ duality transformations on the D0-D4 solution in 0710.4967.Comment: 20 pages, LaTe

Efficacy of a topical formulation of henna (Lawsonia inermis L.) in contact dermatitis in patients using prosthesis: A double-blind randomized placebo-controlled clinical trial

Background: Contact dermatitis is a common complication in prosthetic limb users. There are no effective, available and cheap treatments for skin problems of these patients. In traditional Iranian medicine, henna (Lawsonia inermis L.) is a plant that has anti-inflammatory, antimicrobial and skin-enhancing properties, all of which are beneficial for people with artificial limbs. The aim of this study was to assess the efficacy of a topical henna preparation in management of contact dermatitis in patients using lower limb prosthetics. Methods: The current randomized, double-blind, placebo-controlled clinical trial was conducted on ninety-five participants with lower extremity amputation using limb prosthetics, aged 12�70 years who complained of contact dermatitis. They were randomly assigned to receive either two weeks of topical henna preparation every night as the intervention group, or topical placebo as the control group. Participants were instructed to spread henna preparation on the surfaces of the amputated limb that were in contact with the prosthesis. Severity of contact dermatitis symptoms was set as the primary outcome measure. Edema, papules and erythema were evaluated by a physician using standard color atlas. Secondary outcomes included symptoms such as burning, itching, pain, thickness and skin sweating evaluated by a self-administered questionnaire. Results: A significant improvement was observed in the symptoms of contact dermatitis including skin edema, itching, sweating, skin thinning and pain (p-value<0.05) in the henna group compared to the placebo group. Skin burning decreased more in the henna group compared to the placebo group, but this was not statistically significant (p-value = 0.052). Moreover, skin redness significantly increased in the henna group (p-value = 0.001). Conclusion: Topical formulation of henna might be a complementary choice for improving contact dermatitis in patients using lower limb prosthetics. © 2020 Elsevier Lt

Diagnosis of Periprosthetic Joint Infections in Clinical Practice

The diagnosis of a periprosthetic joint infection (PJI) can be challenging, either because of the variable clinical presentation or because of previous antimicrobial treatment interfering with the detection of the pathogen. In recent years, various means to diagnose PJI have been analyzed. These include invasive and non-invasive laboratory tests, imaging procedures, and novel techniques such as sonication of implants and the use of molecular microbiology. In this review, both established and novel diagnostic procedures are presented. An algorithm for detecting PJI in patients with acute and chronic symptoms is proposed
