Purpose: To report the frequency of nonorganic visual loss (NOVL) and associated psychopathology in children.
Methods: A total of 973 children were examined in our ophthalmology practice between 2006 and 2009. Basic ophthalmologic exploration (visual acuity, stereopsis, cycloplegic refraction, ocular motility, pupil dynamics, biomicroscopy, indirect ophthalmoscopy) and specific tests for NOVL diagnosis were performed (confusion with lenses test, mirrors test, Roth test, Bravais test). We also investigated the psychosocial situation and associated psychiatric problems.
Results: Thirty children were diagnosed with NOVL. The mean age of the children was 8.93 years (± 2.61); 70% were girls. September was the commonest month of presentation (26.7%) and unilateral (3.3%) or bilateral (80%) visual loss was the most frequent symptom (83.3% in total). In 20% of cases we detected psychosocial anomaly and 40% were seeking to wear glasses.
Conclusions: Malingering in children is very frequent. We can make the diagnosis with simple tests. It is not necessary to perform imaging and electrophysiologic testing, thus avoiding unnecessary examinations as well as absenteeism from work for parents and health care costs.

Delta large-channel endoscopy versus unilateral biportal endoscopy decompressive laminectomy for lumbar spinal stenosis: a prospective randomized controlled trial.
J Orthop Surg Res
January 2025
Center of Medical Genetics, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, 610041, China.
Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Department of Retina and Vitreous, Narayana Nethralaya, #121/C, 1st R Block, Chord Road, Rajaji Nagar, Bengaluru, Karnataka, 560010, India.
Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.
Cerebellar Ataxia, Neuropathy, and Vestibular Areflexia as a Presentation of a Novel DNMT1 Mutation.
Cerebellum
January 2025
Department of Neurology, Division of Neuro-Visual & Vestibular Disorders, The Johns Hopkins University School of Medicine, Johns Hopkins Hospital, 600 N. Wolfe Street, Baltimore, MD, USA.
A 50-year-old woman with a 20-year history of gait instability presented with new-onset vertigo and oscillopsia. Examination revealed bilateral vestibular loss, cerebellar ataxia, sensory neuropathy, a "yes-yes" head tremor, nystagmus and a family history of a similar syndrome. Genetic testing for cerebellar ataxia with neuropathy and bilateral vestibular areflexia syndrome (RFC1) was negative, but whole exome sequencing identified a novel mutation in the DNA methyltransferase 1 (DNMT1) gene, broadening the differential diagnosis for this phenotype.

Purpose: Bone cement-reinforced fenestrated pedicle screws (FPSs) have been widely used in the internal fixation and repair of the spine with osteoporosis in recent years and show significant improvement in fixation strength and stability. However, compared with conventional reinforcement methods, the advantages of bone cement-reinforced FPSs remain undetermined. This article compares the effects of fenestrated and conventional pedicle screws (CPSs) combined with bone cement in the treatment of osteoporosis.
