Features and evaluation of mucormycosis in COVID-19 patients from two referral hospitals in Iran.

Objectives: The present study aimed to assess the features, clinical characteristics, and species diversity among patients admitted to referral Hospitals for SARS-CoV-2 pneumonia and mucormycosis in Tehran, Iran, and the relationship between seasonal and species diversity was considered.

Methods: Confirmed COVID-19 patients with a positive reverse-transcriptase real-time (rRT-PCR) test for SARS-CoV2 were primarily included based on clinically suspected mucormycosis infection and confirmed by histopathology and mycology examination of biopsy specimens. The PCR technique was performed by the amplification of the high-affinity iron permease 1 (FTR1) gene for identification and discrimination between Rhizopus arrhizus and non- Rhizopus arrhizus isolates.

Complications and outcomes of cochlear implantation in children younger than 12 months: A multicenter study.

Objectives: Evidence suggests that Cochlear Implantation (CI) is a beneficial approach for auditory and speech skills improvement in children with severe to profound hearing loss. However, it remains controversial if implantation in children <12 months is safe and effective compared to older children. The present study aimed to determine whether children's ages affect surgical complications and auditory and speech development.

Randomized Clinical Trial Comparing Bucket Handle and Cartilage Tympanoplasty Techniques for the Reconstruction of Subtotal or Anterior Tympanic Membrane Perforation.

Objective: The purpose of the study is to compare the clinical outcome of the two techniques of Bucket Handle Tympanoplasty and Cartilage Tympanoplasty in achieving success in graft survival as well as acceptable auditory results. 60 patients who suffered chronic otitis media with anterior perforation of the tympanic membrane were chosen. The patients were randomly assigned using Block Randomization Method of two groups including patients who underwent Bucket Handle Tympanoplasty ( = 30) or those that underwent Cartilage Tympanoplasty ( = 30).

Laryngeal Langerhans Cell Histiocytosis Presenting with Neck Mass in an Adult Woman.

Langerhans cell histiocytosis (LCH) is a very rare condition that commonly affects the head and neck region. There are very few cases of isolated laryngeal involvement by LCH, mostly reported in pediatric patients. Here, we report a case of laryngeal LCH in a 62-year-old woman presenting with a neck mass several weeks ago.
