Introduction: As far as it is known, long-lasting immunosuppressive therapy might put patients with solid organ transplantation (SOT) at increased risk for severe to profound sensorineural hearing loss, eventually leading to cochlear implantation (C.I). So, the main aim of the present study is to evaluate their auditory perception performance after cochlear implantation. Materials and Methods: This case-series study assessed the auditory perception performance of our center's six cochlearimplanted patients who had undergone solid organ transplantation before. The patients' age range was between 3 to 68 years old. Two participants (Female/male) had received liver transplantation, and the rest (two males and two females) had undergone kidney transplantation. The assessment was conducted through the CAP (Categories of Auditory Performance) test in the first month of cochlear implantation and 12 months later. Results: Except for one patient (A 3-year-old girl) who has recently received a cochlear implantation device, and her rehabilitation program is in progress, the auditory perception performance of others improved from 2 to at least six scores. Also, no wound infection, mastoiditis, or bacterial meningitis occurred after cochlear implantation. Conclusion: Immunosuppressive therapy, hemodialysis, infections, and long-lasting medication might lead to severe to profound sensory neural hearing loss in organ-transplanted patients. In recent years, cochlear implantation has been considered a final solution to help this group of patients to hear and communicate better. [ABSTRACT FROM AUTHOR]

Introduction: Many studies have been done on the use of aloe vera in wound healing, but fewer studies were done on the influence of this material on the reduction of the alar scar. Therefore, we evaluated the effect of a newly made aloe vera cream on alar wound healing after rhinoplasty. Materials and Methods: This was a randomized, double-arm, parallel-group, double-blind controlled trial and was done from June 2021 to February 2022. External wedge resection was done for all patients. The patients were randomly assigned to receive aloe vera cream (n=31) (intervention group) or Face Doux cream (comparison group) (n = 29). A pharmacist prepared the aloe vera cream. The primary outcome measure was the wound scar status which was assessed by two Questionnaires, including the mean Patient Scar Assessment Questionnaire (PSAQ) and Vancouver Scar Scale (VSS). Randomization and Blinding were done. Results: The mean PSAQ was significantly lower in group A after two weeks (26.9 versus 31.5, P<0.001), after two months (15.7 versus 19.6, P=0.04), and six months follow-up (8.8 versus 11.8, P=0.005). The mean VSS was significantly lower in group A after two weeks (5.6 versus 7.1, P=0.001), after two months (3.5 versus 4.9, P=0.002), and six months (1.2 versus 2.7, P<0.001). Repeated measurement analysis showed that both interventions significantly affected PSAQ and VSS. Conclusion: Although both interventions had a significant effect on PSAQ and VSS, compared to Face Duox, the topical use of Aloe Vera cream significantly reduced scar formation after alar resection, both statistically and clinically.

Objective: Otitis media with effusion is common in children with cleft palates. This study aimed to investigate the link between palatal closure techniques and audiological outcomes. Methods: In this retrospective‐prospective cohort study, we examined the relationship between palate repair techniques and hearing outcomes in children with cleft palates. From 2017 to 2022, 190 ears of 95 cleft patients were studied at the Cleft Lip and Palate Department of Shiraz University of Medical Sciences. Variables assessed included the surgical technique, cleft severity, auditory brainstem response (ABR) threshold, and tympanometry configuration. Results: The mean ABR improved from a prepalatoplasty value of 39.51(11.62) decibels (dB) to a postpalatoplasty mean of 26.61(11.60) dB (Cohen's d: 1.12 [95% CI; 0.90–1.34]). Initially, 87.9% of the studied ears exhibited abnormal tympanometry, but this significantly decreased to 47% postsurgery (risk ratio: 4.43 [95% CI; 1.20–16.43]). When compared with Sommerlad intravelar veloplasty, the Nadjmi modified Furlow palatoplasty was associated with a notably lower mean ABR (β: −6.58 [95% CI: −10.43 to −2.73], p‐value =.001) and a reduced frequency of abnormal tympanometry (odds ratio [OR]: −1.10; 95% CI: −1.85 to −0.36, p‐value =.004). Factors like prepalatoplasty ABR, cleft palate severity, gender, and syndromic did not confound these findings. Conclusions: Although the Nadjmi modified Furlow palatoplasty showed better results, our findings indicate a significant improvement in ABR and tympanometry outcomes for both techniques. Future randomized controlled trials are suggested to confirm the influence of palatal closure techniques on audiological outcomes. Level of Evidence: 3b. This study evaluated the impact of palatal closure techniques on audiological outcomes in children with cleft palates, comparing Sommerlad intravelar veloplasty and the Nadjmi modified Furlow palatoplasty. The results indicated a significant improvement in auditory brainstem response and tympanometry outcomes with both techniques, with the Nadjmi modified Furlow showing notably better results, and future trials are suggested to confirm these findings.

Introduction: Multiple sclerosis (MS) is a lifelong disease of the brain and spinal cord. Fingolimod is an oral drug which modulates the S1P receptor and is used for relapsing remitting form of MS and can causes rebound activity if it is ceased even in a short period of washout time. Case Report: Here, we introduce a young girl, a known case of MS, who developed reversible isolated unilateral sensory-neural hearing loss along imaging activity two weeks after stopping fingolimod. The patient responded well to the intravenous corticosteroid therapy which is the first line treatment of new MS attack. Conclusion: fingolimod cessation can cause rebound activity in a short period of the time. It is important to consider any new neurological sign and symptom as a rebound activity during washout time. Although SNHL is not common in MS, it could be presented as an unusual manifestation of rebound relapse after stopping fingolimod. [ABSTRACT FROM AUTHOR]

In the present study, we have mainly investigated the nature of interactions in Ln3+ (Ln = La, Nd, Pm, Sm, Eu) complexes with amidocarbamoyl methyl phosphine oxide (CMPO) and amidocarbamoyl propyl phosphine oxide (CPPO) ligands based on density functional theory (DFT) approaches. In the first step, thermodynamical properties for complexation of CMPO and CPPO ligands with Ln3+ cation series have been determined in the gas phase and with the presence of three solvents: n-hexane, chloroform and toluene, via polarized continuum model (PCM) computations. The trend of metal-ligand interaction strength has been analyzed and compared with the trend of ionic hardness within the series of lanthanide cations and different size of alkyl chain of amidocarbamoyl phosphine oxide ligand. The calculated thermochemical results in the gas and solution phases reveals that there is a consistency between increasing trend in the hardness of Ln3+ cation series and also electron-donating property of alkyl chain with increasing in thermodynamical stability of [Ln-CMPO]3+ and [Ln-CPPO]3+ complex series. We have also demonstrated that in the complexation reaction of all complex series, using n-hexane as solvent is more favorable thermodynamically than chloroform and toluene. It should be stated that this issue has been observed in many experiments. Finally, analysis of calculated deformation energies and also the variation in bond order of some selected key bonds in CMPO and CPPO ligands and their corresponded Ln+3 complexes series show a similar trend with increasing in the hardness of Ln3+ cation series and electron-donating of alkyl chain of amidocarbamoyl phosphine oxide ligand.
