• There are patients with early-onset LCHAD deficiency with poor metabolic control despite standard therapy. • The frequency and severity of rhabomyolysis was decreased dramatically with triheptanoin in the presented case. • The effect of triheptanoin on LCHADD-retinopathy needs to be monitored. Early-onset long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (LCHAD) deficiency is a fatty acid β-oxidation disorder with a poor prognosis. Triheptanoin, an anaplerotic oil with odd-chain fatty acids can improve the disease course. The female patient presented here was diagnosed at the age of 4 months, and treatment was started as fat restriction, frequent feeding, and standard medium-chain triglyceride supplementation. In follow-up, she had frequent rhabdomyolysis episodes (∼8 per year). At the age of six, she had 13 episodes in 6 months, and triheptanoin was started as part of a compassionate use program. Following unrelated hospital stays due to multisystem inflammatory syndrome in children and a bloodstream infection, she had only 3 rhabdomyolysis episodes, and hospitalized days decreased from 73 to 11 during her first year with triheptanoin. Triheptanoin drastically decreased the frequency and severity of rhabdomyolysis, but progression of retinopathy was not altered. [ABSTRACT FROM AUTHOR]

Cogan's syndrome (CS) is a rare inflammatory disease characterized by interstitial keratitis or uveitis, vestibular impairment, and progressive hearing loss, commonly bilateral. Although glucocorticoids are fundamental treatment options, in most cases, hearing loss gradually worsens. Herein we report 2 pediatric cases of CS who were treated with corticosteroids and methotrexate. One patient had a cochlear implant, and the hearing of the other patient improved with treatment. Also, a systematic literature review was conducted for articles including pediatric CS patients. In the literature, 34 articles describing 44 pediatric patients with CS were identified. Sudden hearing loss (95.3%) and ocular symptoms (92.5%) were the most common manifestations in these patients. Also, aortic involvement was present in 19.5% of patients in the literature. Otorhinolaryngologists, ophthalmologists, and pediatricians should collaborate to diagnose and manage CS to prevent progressive hearing loss and eye involvement. [ABSTRACT FROM AUTHOR]

Purpose: To develop an algorithm for the diagnosis of Behçet's disease (BD) uveitis based on ocular findings. Methods: Following an initial survey among uveitis experts, we collected multi-center retrospective data on 211 patients with BD uveitis and 207 patients with other uveitides, and identified ocular findings with a high diagnostic odds ratio (DOR). Subsequently, we collected multi-center prospective data on 127 patients with BD uveitis and 322 controls and developed a diagnostic algorithm using Classification and Regression Tree (CART) analysis and expert opinion. Results: We identified 10 items with DOR >5. The items that provided the highest accuracy in CART analysis included superficial retinal infiltrate, signs of occlusive retinal vasculitis, and diffuse retinal capillary leakage as well as the absence of granulomatous anterior uveitis or choroiditis in patients with vitritis. Conclusion: This study provides a diagnostic tree for BD uveitis that needs to be validated in future studies. [ABSTRACT FROM AUTHOR]
