Introduction: High-frequency audiometry may contribute to the early detection of hearing loss caused by ototoxic medications. Many ototoxic drugs are widely used in the treatment of patients with cystic fibrosis. Early detection of hearing loss should allow known harmful drugs to be identified before the damage affects speech frequencies. The damage caused by ototoxicity is irreversible, resulting in important social and psychological consequences. In children, hearing loss, even when restricted to high frequencies, can affect the development of language.
Objective: To investigate the efficacy and effectiveness of hearing monitoring through high-frequency audiometry in pediatric patients with cystic fibrosis.
Methods: Electronic databases PubMed, MedLine, Web of Science and LILACS were searched, from January to November 2015. The selected studies included those in which high-frequency audiometry was performed in patients with cystic fibrosis, undergoing treatment with ototoxic drugs and published in Portuguese, English and Spanish. The GRADE system was chosen for the evaluation of the methodological quality of the articles.
Results: During the search process carried out from January 2015 to November 2015, 512 publications were identified, of which 250 were found in PubMed, 118 in MedLine, 142 in Web of Science and 2 in LILACS. Of these, nine articles were selected.
Conclusion: The incidence of hearing loss was identified at high frequencies in cystic fibrosis patients without hearing complaints. It is assumed that high-frequency audiometry can be an early diagnostic method to be recommended for hearing investigation of patients at risk of ototoxicity.

The diagnostic dilemma of adrenal vascular tumors: analysis of 21 cases and systematic review of the literature.

Purpose: Adrenal vascular tumors are mainly represented by adrenal cavernous hemangiomas (ACHs) and adrenal cystic lymphangiomas (ACLs). Their radiological features often overlap with malignant tumors, therefore ruling out malignancy becomes mandatory. We analyzed clinical, radiological, and histopathological data to identify specific characteristics of these tumors.

We aimed to investigate the effects of 24-month lumacaftor/ivacaftor (LUM/IVA) therapy in pediatric CF patients (pwCF). This observational study included pwCF homozygous for F508del mutation treated between 2021 and 2023.

Background: Highly effective modulator therapies (HEMT) including ivacaftor (IVA) and elexacaftor/tezacaftor/ivacaftor (ETI) have transformed treatment for people with cystic fibrosis (pwCF). However, non-HEMT-responsive mutations are more common in pwCF of non-White race/ethnicity; introduction of HEMT might have exacerbated racial/ethnic disparities in CF care.
Methods: Using the Scientific Registry of Transplant Recipients, we identified all lung transplant candidates and recipients 05/2005-12/2022 and categorized them by diagnosis (CF/non-CF), race/ethnicity (non-Hispanic White/Black/Hispanic) and era [Pre-HEMT (2005-1/30/2012), IVA (1/31/2012-10/30/2019), ETI (10/31/2019-12/31/2022)].

Objectives: Pandoraea apista is notable for its multidrug resistance and is frequently identified in patients with cystic fibrosis or other chronic lung diseases, where it contributes to persistent lung infections. In this study, we describe a strain of P. apista harboring the bla, isolated from the bronchoalveolar lavage (BAL) fluid of an inpatient in China.

Neurenteric cysts, rare benign tumors, are most often found in the cervical or thoracic spinal cord, with intracranial occurrences being extremely uncommon. This case report describes a 52-year-old female with a neurenteric cyst in the cerebellopontine angle, presenting with headaches and balance disturbances. Magnetic resonance imaging (MRI) revealed a cystic lesion causing hydrocephalus, and surgical removal was performed using a retrosigmoid approach.
