Purpose: To evaluate the current French screening guidelines for retinopathy of prematurity (ROP) and to suggest modifications to it.
Methods: In this multicentric retrospective, noncomparative, interventional case series we included infants with a gestational age (GA) ≤32 weeks who were screened for ROP by fundus examination between 2011 and 2018. Main Outcome Measures were the presence of ROP and the need for treatment.
Results: A total of 2246 children with a mean GA of 28.9 ± 2.0 weeks and mean birth weight (BW) of 1141.1 ± 332.0 g were screened. Retinopathy of prematurity (ROP) was found in 683 infants (30.4%), of whom 145 (6.5%) had type 2 ROP and 58 (2.6%) had type 1 ROP. Mean GA of infants with type 1 ROP needing treatment was 25.9 + 1.5 weeks (range: 23.6-30) and mean BW was 774.1 ± 173.7 g (range: 540-1400). Both GA and BW had an impact on the development of type 1 and 2 ROP. None of the infants needing treatment had a GA of 31 weeks or more. None of the children needed treatment before 33 weeks of postmenstrual age (PMA) or 6 weeks of postnatal age (PNA).
Conclusion: It seems possible to decrease the screening of premature infants to ≤31 weeks of GA and to start screening at 31 weeks PMA for infants having a GA < 26 weeks and at 6 weeks PNA for more mature children.

Lobectomy vs. MRgLITT in Temporal Lobe Epilepsy (TLE): A Pilot Study Investigating Vestibulo-Spatial Functions.

: About 65 million people worldwide are affected by epilepsy, with temporal lobe epilepsy being the most common type resistant to drugs and often requiring surgical treatment. Although open surgical approaches, such as temporal lobectomy, have been the method of choice for decades, minimally invasive MRgLITT has demonstrated promising results. However, it remains unknown whether patients who underwent one of these two approaches would show better performance on vestibulo-spatial tasks.

Objective To explore the role of the base mismatch repair gene Mutyh in retinopathy of prematurity(ROP). Methods Mutyh(-/-)and wild-type(WT)mice were used for the modeling of oxygen-induced retinopathy.The retinal oxidative stress was examined,and the ultrastructures of photoreceptors and mitochondria were observed.
View Article and Find Full Text PDFRetinopathy of prematurity (ROP) and diabetic retinopathy (DR) are ocular disorders in which a loss of retinal vasculature leads to ischemia followed by a compensatory neovascularization response. In mice, this is modeled using oxygen-induced retinopathy (OIR), whereby neonatal animals are transiently housed under hyperoxic conditions that result in central retina vessel regression and subsequent neovascularization. Using endothelial cell (EC)-specific gene deletion, we found that loss of two ETS-family transcription factors, ERG and FLI1, led to regression of OIR-induced neovascular vessels but failed to improve visual function, suggesting that relevant retinal damage occurs prior to and independently of neovascularization.
