Article Synopsis
  • The study aimed to explore patient interactions during disorders of arousal (DoA), despite current diagnoses focusing on absent responsiveness.
  • It involved three studies: a questionnaire on verbal responsiveness in 61 patients, auditory stimulation during sleep in 14 patients, and analysis of 364 home videos from 19 patients.
  • Findings revealed that many patients reported occasional conversations during episodes, indicating varying levels of consciousness and responsiveness, which challenge existing diagnostic criteria for DoA.

Article Synopsis
  • The study investigated the link between air pollution and cataract surgery incidence in older adults in Bordeaux, France.
  • Researchers followed 829 participants aged 65 and older from 1999-2017, monitoring their cataract surgeries and estimating their long-term air pollution exposure.
  • Results showed that long-term exposure to nitrogen dioxide (NO) at levels ≥40 μg/m was significantly associated with increased incidence of cataract surgery, suggesting that meeting air quality standards could benefit public health.

Article Synopsis
  • Clozapine is effective for treatment-resistant schizophrenia but can cause significant side effects, notably excessive daytime sleepiness, which is a form of hypersomnolence.
  • A systematic review examined how clozapine affects objective measures of hypersomnolence, analyzing six studies using various testing methods like polysomnography (PSG).
  • Initial findings showed clozapine led to longer sleep times and quicker sleep onset, but these effects did not last beyond 4-6 weeks, indicating a need for further long-term research on sleep patterns and wakefulness in clozapine-treated patients.

Article Synopsis
  • Inherited retinal diseases (IRDs) cause people to lose their vision slowly, and there are over 270 genes that can cause these problems.
  • One specific gene, RLBP1, leads to different eye disorders depending on changes in that gene, affecting proteins important for seeing.
  • Researchers created a method to treat these disorders using gene therapy, and they discovered a new form of the CRALBP protein that could help improve treatments in both humans and mice.

  • Extended-release sodium oxybate (ON-SXB) showed significant improvements in narcolepsy symptoms in the REST-ON trial, which was a phase 3 study comparing it to a placebo.
  • This analysis looked at the effectiveness of ON-SXB in patients both with and without the use of other alerting medications.
  • Results indicated that ON-SXB led to substantial improvements in sleep latency, cataplexy episodes, and overall sleepiness, regardless of whether participants were using alerting agents.

Department of Otolaryngology and Head and Neck Surgery, Gui de Chauliac Hospital, CHRU Montpellier - Centre Hospitalier Régional Universitaire, Université de Montpellier, Montpellier, France.

The cochlear aqueduct (CA) is a bony canal located at the base of the scala tympani of the cochlea. It connects the inner ear perilymph fluid to the cerebrospinal fluid of the posterior cerebral fossa. Its function is not well understood, as it seems to be patent in only a fraction of adult patients.

Traumatic orbital fracture with prolapse of the globe into the paranasal sinuses is very rare. The visual prognosis is poor, and the medical and surgical management is still a topic of debate. We herein describe an extremely rare case of globe dislocation into the left maxillary sinus with complete recovery of visual acuity.

Introduction: Anti-vascular endothelial growth factor (VEGF) is generally given using pro re nata or "treat-and-extend" (T&E) regimens for neovascular age-related macular degeneration (nAMD). Randomized clinical trials have reported that T&E is superior to Pro re nata (PRN), but results from clinical trials may not always be replicated in clinical practice. Real-world data comparing T&E and PRN regimens for nAMD are limited.

Article Synopsis
  • X-linked retinitis pigmentosa (XLRP) causes progressive vision loss primarily in males, with carrier females exhibiting a range of severities; about 70% of cases are linked to mutations in the RPGR gene.
  • The terminal exon ORF15 of the RPGR gene is challenging to sequence due to its repetitive nature, complicating molecular diagnostics.
  • A recent study validates a long-read sequencing method that improved detection rates of ORF15 variations to nearly 100% after additional visual inspection, suggesting this approach should be the first screening choice for XLRP cases.

Kleine-Levin syndrome. Clinical boarderlands based on a thorough analysis of 475 case reports.

Sleep Med

September 2024

Institute for Neurosciences of Montpellier INM, Montpellier University, INSERM, Montpellier, France.

Objective/background: Kleine-Levin syndrome (KLS) is a rare sleep disorder characterized by recurrent episodes of severe hypersomnolence in association with various degrees of cognitive impairment, perceptive abnormalities, apathy, behavioral disturbances. Some of these symptoms, hypersomnolence, compulsive eating and increased sexual drive may be replaced by their opposites or alternate with them. Remarkably enough, these « atypical symptoms » have never been enlighted nor compared in frequency with corresponding typical symptoms.

Introduction: The LIfestyle for BRAin Health (LIBRA) index yields a dementia risk score based on modifiable lifestyle factors and is validated in Western samples. We investigated whether the association between LIBRA scores and incident dementia is moderated by geographical location or sociodemographic characteristics.

Methods: We combined data from 21 prospective cohorts across six continents (N = 31,680) and conducted cohort-specific Cox proportional hazard regression analyses in a two-step individual participant data meta-analysis.

The differential diagnosis of narcolepsy type 1, a rare, chronic, central disorder of hypersomnolence, is challenging due to overlapping symptoms with other hypersomnolence disorders. While recent years have seen significant growth in our understanding of nocturnal polysomnography narcolepsy type 1 features, there remains a need for improving methods to differentiate narcolepsy type 1 nighttime sleep features from those of individuals without narcolepsy type 1. We aimed to develop a machine learning framework for identifying sleep features to discriminate narcolepsy type 1 from clinical controls, narcolepsy type 2 and idiopathic hypersomnia.
