- Abstract
Background: Radiotherapy (RT) involves the use of ionizing radiation in treating malignancies and benign disorders. However, RT damages target and healthy surrounding tissues in a dose-dependent manner. This effectively reduces patient compliance and quality of life, thereby warranting the prevention of RT-induced adverse effects on skin. Adipose-derived stem cells (ASCs) are used to treat RT-induced damage and platelet-rich plasma (PRP) provides a scaffold that potentiates the effects of ASCs. Thus, the aim of this study was to determine the mechanism employed by ASCs and PRP in protecting against RT-induced adverse effects., Methods: We have established an immunodeficient mouse transplantation model using which human hair follicular units were implanted. When the follicular units were macroscopically and microscopically mature and anagenic, we administered localized RT. Subsequently, the mice were randomly divided into 4 groups based on the subcutaneous injection of the following to the irradiated transplantation site: saline, PRP, ASCs, and a combination of ASCs and PRP. Next, we used macroscopic and microscopic analyses to determine the protective effects of the injected solutions on skin and hair follicles., Results: Adipose-derived stem cells reduced RT-induced adverse effects, such as impaired wound healing, alopecia, skin atrophy, and fibrosis by suppressing inflammation, dystrophy, degeneration, connective tissue synthesis, and apoptosis and increasing cellular proliferation, differentiation, and signaling. Moreover, these effects were augmented by PRP., Conclusions: Thus, co-administering ASCs with PRP in mice prevented RT-induced adverse effects and can be tested for use in clinical practice., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
Background/aim: The Zurich Chronic Middle Ear Questionnaire (ZCMEI-21) is a newly-developed German-language questionnaire. The purpose of this study was to analyze the quality of life (QoL) of chronic otitis media (COM) patients and translate, transculturally adapt, and validate the ZCMEI-21 into Turkish., Materials and Methods: Based on internationally accepted guidelines, the ZCMEI-21 was translated into Turkish. To assess its validity, the total score of the ZCMEI-21-Tur was compared to the scores taken from the original validation study and a question that was directly related to the health-related QoL (HRQoL), as well as the general criterion EQ-5D-5L. Questionnaires were completed by healthy volunteers and the results were evaluated statistically., Results: A total of 80 COM patients and 40 healthy volunteers were prospectively enrolled in this study. Regarding internal consistency, the questionnaire showed a Cronbach α of 0.94, which indicated high internal consistency. Moreover, internal consistency was also determined to be excellent for the Cronbach α of the individual subscales, as follows: ear sign symptoms, 0.79; hearing, 0.83; psychosocial impact, 0.91, and medical resources, 0.84., Conclusions: The ZCMEI-21 was translated into Turkish and validated. Therefore, the ZCMEI-21-Tur was suitable for use in assessing HRQoL in adult patients with COM., Competing Interests: The authors have no funding, financial relationships, or conflicts of interest to disclose, (This work is licensed under a Creative Commons Attribution 4.0 International License.)

- Abstract
Objective: To evaluate the effect of dysphonia in children, several methods have been developed, including the Pediatric Voice Outcome Survey, the Pediatric Voice Handicap Index, and the Pediatric Voice-Related Quality of Life (PVRQOL) Survey. The aim of this study was to analyze the validity of the Turkish version of the PVRQOL Survey., Methods: The PVRQOL Survey consists of 10 questions that evaluate the effects of dysphonia on quality of life. We translated it into Turkish by working with two translators and faculty from the English Grammar and Literature Department. The Turkish version was translated back into English by two bilingual individuals to assess accuracy. The final version was tested by 15 parents for pilot study. Following the pilot study, we enrolled 52 children who had been admitted to the outpatient clinic with dysphonia and 79 children who had no voice complaints. The parents of the children under 7 years were asked to answer the survey. Children aged between 7 and 9 years completed the survey with their parents, and children over 9 years completed the survey by themselves., Results: The results of the pilot study revealed no difference between the two groups. Intergroup comparisons revealed that there were statistically significant differences between the control and patient groups in terms of question responses. When the total scores of the two groups were compared, there was a significant difference., Conclusion: The Turkish version is a valid and reliable instrument for assessing dysphonic patients and healthy subjects., (Copyright © 2018 The Voice Foundation.

- Abstract
Objective: The aim of this study was to analyze the influence of deviated nasal septum (DNS) type on nasal mucociliary clearance, quality of life (QoL), olfactory function, and efficiency of nasal surgery (septoplasty with or without inferior turbinate reduction and partial middle turbinectomy)., Methods: Fifty patients (20 females and 30 males) with septal deviation were included in the study and were divided into 6 groups according to deviation type after examination by nasal endoscopy and paranasal computed tomography. The saccharin clearance test to evaluate the nasal mucociliary clearance time, Connecticut Chemosensory Clinical Research Center smell test for olfactory function, and sinonasal outcome test-22 (SNOT-22) for patient satisfaction were applied preoperatively and postoperatively at the sixth week after surgery., Result: Nasal mucociliary clearance, smell, and SNOT-22 scores were measured before surgery and at the sixth week following surgery. No significant difference was found in olfactory and SNOT-22 scores for any of the DNS types (both convex and concave sides) (P > 0.05). In addition, there was no difference in the saccharin clearance time (SCT) of the concave and convex sides (P > 0.05). According to the DNS type, the mean SCT of the convex sides showed no difference, but that of the concave sides showed a difference in types 3, 4, 5, and 6. These types had a prolonged SCT (P < 0.05). Olfactory scores revealed no difference postoperatively in types 5 and 6 but were decreased significantly in types 1 to 4 (P < 0.05). There was no significant difference in the healing of both the mucociliary clearance (MCC) and olfactory functions. SNOT-22 results showed a significant decrease in type 3., Conclusion: All DNS types disturb the QoL regarding nasal MCC and olfaction functions. MCC values, olfactory function, and QoL scores are similar among the DNS types. Both sides of the DNS types affect the MCC scores symmetrically. Septal surgery improves olfaction function and QoL at the sixth week following surgery but disturbs nasal MCC; thus, the sixth week is too early to assess nasal MCC.

- Abstract
Objectives/hypothesis: To evaluate the psychological effects of dysphonia in voice professionals compared to non-voice professionals and in both genders., Study Design: Cross-sectional analysis., Methods: Forty-eight 48 voice professionals and 52 non-voice professionals with dysphonia were included in this study. All participants underwent a complete ear, nose, and throat examination and an evaluation for pathologies that might affect vocal quality. Participants were asked to complete the Turkish versions of the Voice Handicap Index-30 (VHI-30), Perceived Stress Scale (PSS), and the Hospital Anxiety and Depression Scale (HADS). HADS scores were evaluated as HADS-A (anxiety) and HADS-D (depression). Dysphonia status was evaluated by grade, roughness, breathiness, asthenia, and strain (GRBAS) scale perceptually. The results were compared statistically., Results: Significant differences between the two groups were evident when the VHI-30 and PSS data were compared (P = .00001 and P = .00001, respectively). However, neither HADS score (HADS-A and HADS-D) differed between groups. An analysis of the scores in terms of sex revealed that females had significantly higher PSS scores (P = .006). The GRBAS scale revealed no difference between groups (P = .819, .931, .803, .655, and .803, respectively). No between-sex differences in the VHI-30 or HADS scores were evident, Conclusions: We found that voice professionals and females experienced more stress and were more dissatisfied with their voices., Level of Evidence: 4., (© 2015 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Objectives: This study aims to analyze the subjective and objective characteristics of tinnitus in sleep bruxism patients., Patients and Methods: The study included 57 patients (12 males; 45 females; mean age 33.89±12.50 years; range 19 to 55 years) with sleep bruxism and tinnitus (sleep bruxism group) and 24 patients (6 males, 18 females; mean age 43.75±16.19 years; range 21 to 58 years) only with tinnitus (control group). Sleep bruxism was diagnosed by the diagnostic criteria of American Academy of Sleep Medicine. Patients were performed pure tone audiometry to detect hearing thresholds at standard and high frequencies. Tinnitus frequency and loudness were assessed. Subjective aspects of tinnitus were identified by tinnitus handicap inventory., Results: The statistical analysis revealed that the sleep bruxism group had significantly lower hearing thresholds except 1000 Hz and 2000 Hz. Tinnitus frequency was between 3000 Hz and 18000 Hz in sleep bruxism group while it was between 6000 and 16000 Hz in control group with no statistically significant difference (p=0.362). Sleep bruxism group had significantly lower tinnitus loudness and tinnitus handicap inventory scores in comparison to control group (p=0.024 and p=0.000, respectively)., Conclusion: Tinnitus caused by sleep bruxism and temporomandibular joint issues has higher frequency and lower loudness compared to patients with only tinnitus.

- Abstract
The purpose of this study was to adapt the Meaning in Life Questionnaire (MLQ) developed by Steger, Frazier, Oishi, and Kaler (2006) into Turkish and examine the measurement and structural invariance of this scale across Turkish (N = 815) and U.S. (N = 207) samples. Our findings indicated that the hypothesized 2-factor model of the MLQ fit the data well for both Turkish and U.S. samples. Results also provided support for the full metric invariance, partial scalar invariance, and partial invariance of residual variances of the MLQ across the 2 samples (i.e., Turkish and U.S.). Supporting the structural invariance, we found that factor variances and covariances were equivalent across the 2 groups. Internal consistency reliability analyses revealed a Cronbach's alpha value of .88 for the MLQ Presence scale and .90 for the Search scale. Our findings also provided preliminary support for the convergent validity of the Turkish version of the MLQ (MLQ-TR). Contrary to findings in other collectivist cultures, the relationship between Search and Presence was negative in Turkish culture. These results support the psychometric properties of the MLQ-TR and its partial equivalence to the original U.S. version.

- Abstract
The purpose of this study was to test whether positive automatic cognitions moderated the relationship between event stressfulness and meaning in life. Measures of these constructs were administered to 232 students and community-dwelling adults. Supporting hypotheses and the literature, positive automatic cognitions moderated the relationship between event stressfulness and meaning in life. For persons with high levels of positive thinking, greater event stressfulness was associated with higher meaning in life. For persons with low levels of positive thinking, greater event stressfulness was associated with lower meaning in life. These results were obtained when controlling for positive affect, as well as the positive affect × event stressfulness interaction. The positive cognitions × event stressfulness interaction accounted for 2.9% of variance, and the overall model accounted for 47% of the variance in meaning in life., (© 2012 American Orthopsychiatric Association.)
