Music Appreciation of Cochlear Implant Users versus Normal Hearing Individuals.

Introduction: Cochlear implants (CI) provide speech perception for patients with sensorineural hearing impairment; nonetheless, listening to music is a daunting challenge for them. The present study aimed to compare Iranian CI users and normal hearing (NH) controls in terms of musical habits and appreciation and investigate the possible effect of background variables. Materials and Methods: A total of 37 CI users who underwent surgery at least 18 months before the study and 59 NH listeners were enrolled in this study. The participants were assigned to two age groups: group A (patients ≥15 years old) and group B (patients <15 years old). They were asked to complete the questionnaires to assess their music engagement. Results: In group A, the mean score of music importance was significantly higher in CI users (8.7±2.1), as compared to that in NH subjects (5.8±2.3) (P=0.005). Participation in professional musical training and singing with music was not significantly different between the groups. In group B, the mean score of desire for music was not significantly different between CI users (8.2±1.8) and NH subjects (7.7±2.0). They participated in professional musical training and had a reaction to music almost equally. Singing with music was significantly less common in the CI group (CI 16[61.5%], NH (40[85.1%]) (P=0.023). Selected background variables had no significant effect on the music tendency and habits of CI users. Conclusions: Iranian CI users tended to have a high level of music appreciation in both adult and children groups. Moreover, CI users and NH controls did not significantly differ in the importance of music, devoted time, participation in musical activities, and musical habits.

Comparison of the efficacy and safety of 308-nm excimer laser with intralesional corticosteroids for the treatment of alopecia areata: A randomized controlled study.

BACKGROUND: Corticosteroids have been the mainstay of treatment for alopecia areata (AA). Recently, the 308-nm excimer laser has been proposed for treating AA. OBJECTIVES: To compare the efficacy and safety of excimer laser with intralesional corticosteroid (ILCS) in AA. METHODS: Patients with at least two alopecic patches were randomly assigned to receive weekly excimer laser treatments or monthly injections of ILCS. Photographs and trichoscopy images were examined at baseline, the last treatment session, and after one month of follow-up. The hair regrowth score was evaluated on a 6-point scale. RESULTS: Sixteen patients with 99 alopecic patches completed the study. At the last treatment session, the mean score of hair regrowth for the laser was significantly lower than the ILCS (p = 0.003). However, after a month of follow-up, the difference was not statistically significant (p = 0.148). Positive response in hair regrowth (≥50%) was achieved in 47% of laser-treated patches and 66% in ILCS-treated ones. Four (25%) and 8 (50%) patients experienced severe adverse events of laser and ILCS, respectively. CONCLUSIONS: The excimer laser was safe and effective in AA. The effect of laser on hair regrowth might be delayed as compared with ILCS.

Pigmented purpuric dermatoses versus purpuric mycosis fungoides: Clinicopathologic similarities and new insights into dermoscopic features.

BACKGROUND: The diagnosis of purpuric mycosis fungoides (PMF) is often challenging to be clinically differentiated from inflammatory diseases such as pigmented purpuric dermatosis (PPD). Dermoscopy as a non-invasive method can be employed for the visualisation of features invisible to the naked eye. OBJECTIVES: This study aimed to survey the dermoscopic findings of PMF in comparison with PPD. METHODS: Forty-one patients with an established diagnosis of PMF (n = 28) and PPD (n = 13) were prospectively recruited. Dermoscopic images were taken by FotoFinder Medicam 1000 (FotoFinder Systems GmbH, Bad Birnbach, Germany). RESULTS: Characteristic dermoscopic patterns consisting of fine short linear vessels (35.7%, P = 0.017) and spermatozoa-like structures (50%, P = 0.014) were found to be significantly more common in PMF lesions, while PPD lesions were typified by erythematous globules (76.9%, P = 0.01), in the background colour of dull red (61.5%, P = 0.01) and reticular pigmentation (61.5%, P = 0.044). CONCLUSIONS: This study showed the usefulness of dermoscopy for the diagnosis of PMF and PPD cases. Studies with long-term follow-up are needed to affirm the value of these dermoscopic patterns in the differentiation between the two entities.

Efficacy and safety of hydrogen peroxide topical solution in treating actinic keratosis: A randomized controlled trial.

Actinic keratosis (AK) is a precancerous skin lesion associated with the development of squamous cell carcinoma. Approved topical treatments for AK are unmet needs. To evaluate the safety and efficacy of hydrogen peroxide topical solution 35% (H2 O2 ) with cryosurgery for the treatment of AKs. Eligible subjects were randomly assigned to receive H2 O2 and cryosurgery on each side of their scalp/face. Patients were assessed at baseline and after 3 months of follow-up. Efficacy was evaluated based on the Actinic Keratosis Area and Severity Index (AKASI) and dermoscopic assessments. Fifteen patients with 98 lesions completed the study. At the follow-up visit, the mean improvement of AKASI from baseline was 1.7 ± 0.9 for H2 O2 and 1.7 ± 0.8 for cryosurgery (p < 0.001, both). Both treatments significantly improved dermoscopic features of yellow scale, white scale, linear-wavy vessels, pigmented dots, and rosette at the end of the 3-month follow-up. Complete dermoscopic response occurred in 57.7% and 73.9% of lesions treated with H2 O2 and cryosurgery, respectively (p > 0.05). Regarding safety, hypopigmentation occurred more frequently in the cryosurgery group (28.3% vs. 9.6%; p = 0.017). Moreover, patients endured more pain with cryosurgery application than H2 O2 (p < 0.001). The effect of H2 O2 solution was comparable to cryosurgery. This treatment was well tolerated and had a favorable safety in patients with AKs.

Clinical and histopathological evaluation of cutaneous angiofibromas.

BACKGROUND: Angiofibromas are common benign skin lesions that are diagnosed clinically and histopathologically. Fibrous papule (FP) is one of the clinical types of angiofibromas located primarily on the nose. METHODS: The cases with the confirmed diagnosis of angiofibroma were enrolled. Demographic features of the patients and clinical characteristics of the lesions were extracted. Moreover, histopathological features of the available slides were microscopically reviewed. RESULTS: From 83 cases of cutaneous angiofibromas, 57 (69%) had lesions consistent with FP. The mean age at diagnosis was 37.7 ± 16.3 years and the most common site of involvement was the nose (53% of cases). Regarding the histopathological evaluation of 71 slides, most cases represented vascular changes (97%) and dermal fibroplasia (87%). Melanin incontinence (41%), acanthosis (31%), and lichenoid features (25%) were other common histopathological findings. Moreover, a sparse inflammatory cell infiltrate was present in 68% of cases. The most prevalent inflammatory cells were lymphocytes (61%) and histiocytes (34%). CONCLUSION: This study presented the histopathological findings of a series of cutaneous angiofibromas. Dermatopathologists should be aware of these features, especially those that are less common, to better diagnose and differentiate them from malignant neoplasms.

The Impact of Facial Asymmetry on the Surgical Outcome of Crooked Nose: A Case Control Study.

BACKGROUND: Facial asymmetry is considered a reason for patient dissatisfaction with the outcome of rhinoplasty. OBJECTIVES: The aim of this study was to evaluate the impact of facial asymmetry on patient postoperative satisfaction with crooked nose and to investigate the relationship between visual perception of asymmetry and anthropometric measurements. METHODS: In this retrospective study, 61 rhinoplasty patients with crooked noses were assessed. Utilizing frontal view photos, pre- and postoperative nasal deviation angles were calculated. The patients were divided into 2 groups based on the visual presence of facial asymmetry. Moreover, anthropometric characteristics of the face were evaluated utilizing facial soft tissue landmarks. Patient satisfaction with surgery outcomes, including both aesthetic and functional aspects, was assessed employing the Persian version of the Standardized Cosmesis and Health Nasal Outcomes Survey. RESULTS: Based on the observations, 19 (30.2%) and 44 (69.8%) patients had I-type and C-type noses, respectively. In both groups, the deviation angle decreased significantly postoperatively (P < 0.001). Regarding the subjective evaluation of facial asymmetry, 22 (34.9%) and 41 (65.1%) cases had symmetric and asymmetric faces, respectively. Anthropometric measurements were also consistent with visual assessments of asymmetry. Satisfaction scores were significantly higher after surgery in all patients; however, there was no significant difference in the mean aesthetic improvement between symmetric (15.83 ± 2.68) and asymmetric faces (15.23 ± 4.46) (P = 0.531). The power of study was 97.8%. CONCLUSIONS: Rhinoplasty in patients with deviated noses and asymmetric faces may have comparable results with symmetric ones.

Cutaneous cysts: a clinicopathologic analysis of 2,438 cases.

BACKGROUND: Benign cutaneous lesions, so-called cysts, are frequently seen in clinics and might evoke cosmetic and psychosocial concerns. AIM: This study aimed to demonstrate the clinicopathologic findings of these lesions and also the importance of histological evaluation for prevention of misdiagnosing a benign-appearing malignant lesion. METHODS: A descriptive study was conducted of 2,438 cases who had a diagnosis of cyst confirmed with pathology. The data of patients over the 6-year period between 2011 and 2017, including gender, age, location, prevalence, complications, and microscopic evaluation, were gathered. RESULTS: From a total of 2,438 records with a clinical diagnosis of mucocutaneous cyst, 2077 had the pathologic diagnosis of cysts. They consisted of 910 women (43.8%) and 1167 men (56.1%) with a mean age of 42. The most common mucocutaneous cysts were epidermal cyst 994 (47.8%) followed by trichilemmal cyst 495 (23.8%). In 479 (19.6%) records, the clinical diagnosis was not congruent with histopathological diagnosis including 45 malignant cases. Basal cell carcinoma in 22 (48.9%) was the most common one. CONCLUSIONS: This study reports on clinical characteristics of cutaneous cysts and the need for a decent diagnostic investigation, like histopathology, for achieving a reliable diagnosis regarding the benign mimicking malignant lesions, especially high risk ones.
