    Background Many studies evaluating the nutritional status of children with cerebral palsy (CP) have focused on energy requirements and protein intake. The present work aimed to assess nutritional status and micronutrient levels of children with (CP). Methods This multicenter, cross-sectional and observational study was conducted in 10 different cities in Turkey. Data were available for 398 participants. Anthropometric measurements, feeding mode, nutritional status, and micronutrient levels were evaluated. Results The study was conducted with 398 participants (303 patients and 95 healthy controls). Statistical analysis showed that according to the Gomez Classification, weight-for-age (WFA) revealed malnutrition in 92.6% of children with CP, based on Centers for Disease Control and Prevention percentiles. Measurements of micronutrient levels showed that zinc levels were low in patients, whereas vitamin A levels were low in controls. Phosphorous and manganese levels were significantly lower in malnourished children than in typical children. The results revealed that children consuming enteral nutrition solutions had higher selenium and lower zinc levels than non-consumers. Conclusions Malnutrition is not only a protein- or calorie-based problem; micronutrient deficiencies might cause severe health problems. Children with chronic neurological disabilities must be carefully evaluated for these issues. Therefore, nutritional interventions should be adapted to nutrition.

    Background: Various etiologies may underlie optic neuritis, including autoantibody-mediated disorders described in the last decade. We re-examined demographic, clinical, laboratory features and prognostic factors in pediatric patients with autoimmune optic neuritis according to current knowledge.Methods: Cases of pediatric ON from 27 centers in Turkiye diagnosed between 2009 and 2022 were included for retrospective evaluation.Results: The study included 279 patients, 174 females and 105 males, with a female-to-male ratio of 1.65. The average age at onset was 12.8 +/- 3.4 years, and mean follow-up, 2.1 years (range: 1-12.1 years). Patients <10 years old were grouped as prepubertal and those >= 10 years old as others. The diagnoses made at the end of follow-up were multiple sclerosis associated optic neuritis (n = 90, 32.3 %), single isolated optic neuritis (n = 86, 31 %), clinically isolated syndrome (n = 41, 14.7 %), myelin oligodendrocyte glycoprotein antibody associated optic neuritis (n = 22, 7.9 %), and relapsing isolated optic neuritis (n = 18, 6.5 %). Predominant diagnoses were myelin oligodendrocyte glycoprotein antibody associated optic neuritis and acute disseminated encephalomyelitis associated optic neuritis in the prepubertal group and multiple sclerosis associated optic neuritis in the older group. Recurrences were observed in 67 (24 %) patients, including 28 with multiple sclerosis associated optic neuritis, 18 with relapsing isolated optic neuritis, 11 with myelin oligodendrocyte glycoprotein antibody associated optic neuritis, 8 with aquaporin-4 antibody related optic neuritis, and 2 with chronic relapsing inflammatory optic neuropathy. Recurrences were more common among female patients. Findings supporting the diagnosis of multiple sclerosis included age of onset >= 10 years (OR=1.24, p = 0.027), the presence of cranial MRI lesions (OR=26.92, p<0.001), and oligoclonal bands (OR=9.7, p = 0.001). Treatment in the acute phase consisted of intravenous pulse methylprednisolone (n = 46, 16.5 %), pulse methylprednisolone with an oral taper (n = 212, 76 %), and combinations of pulse methylprednisolone, plasmapheresis, or intravenous immunoglobulin (n = 21, 7.5 %). Outcome at 12 months was satisfactory, with 247 out of 279 patients (88.5 %) demonstrating complete recovery. Thirty-two patients exhibited incomplete recovery and further combination treatments were applied. Specifically, patients with relapsing isolated optic neuritis and aquaporin-4 antibody related optic neuritis displayed a less favorable prognosis.Conclusion: Our results suggest optic neuritis is frequently bilateral in prepubertal and unilateral in peri- or postpubertal patients. Age of onset 10 or older, presence of oligoclonal bands, and brain MRI findings reliably predict the development of multiple sclerosis. The risk of developing multiple sclerosis increases mostly during the second and third years of follow-up. Relapsing isolated optic neuritis remains a separate group where the pathogenesis and outcome remain unclear. Investigation of predisposing and diagnostic biomarkers and long follow-up could help to define this group.
