Osteogenesis imperfecta (OI) is a group of rare hereditary collagen disorders. Hearing loss (HL) is a known complication linked to changes in the bones of the middle ear seen in OI. We aimed to determine the prevalence, age at debut, incidence, and risk of HL, surgery on bones of the middle ear, and use of hearing aids.

- Intraoperative cochlear monitoring using electrocochleography (ECochG) aims to preserve residual hearing during cochlear implant (CI) surgery by analyzing the relationship between ECochG signals, electrode position, and hearing preservation.
- Research involved recording ECochG signals during and after the insertion of CI electrodes in six adult patients, focusing on how electrode placement affected signal amplitude.
- Results showed that patients with preserved low-frequency hearing had increased signal amplitudes closer to the stimulation sources, while those with severe hearing loss exhibited a rise and subsequent drop in signal amplitude, indicating the importance of electrode positioning and potential trauma effects.
In recent years, tools for early detection of irreversible trauma to the basilar membrane during hearing preservation cochlear implant (CI) surgery were established in several clinics. A link with the degree of postoperative hearing preservation in patients was investigated, but patient populations were usually small. Therefore, this study's aim was to analyze data from intraoperative extracochlear electrocochleography (ECochG) recordings for a larger group.

Children affected by coronavirus disease 2019 (COVID-19) with preexisting comorbidities are at risk of complications. Monoclonal antibodies prevent severe COVID-19 courses in adults but data on children are scarce. Here we report on the use of Sotrovimab in 14 children at risk of severe disease treated at the University of Cologne Children's Hospital.

- This study explores how chronic kidney disease-mineral and bone disorder (CKD-MBD) parameters affect kidney transplant outcomes in children, highlighting a lack of information in this area.
- Data was collected from 1210 pediatric patients across Europe, analyzing the impact of parathyroid hormone, calcium, phosphate, and vitamin D levels on kidney function over 5 years post-transplant.
- The findings indicate that hyperparathyroidism may independently increase the risk of kidney transplant dysfunction, while hyperphosphatemia's impact appears related to declines in kidney function rather than being an independent factor.
