Background/purpose: Myasthenia gravis is an autoimmune disease that usually responds positively to treatment with thymectomy. Various approaches via video-assisted thoracic thymectomy as a substitute for conventional sternotomy have been reported. We reported a less invasive technique for thymectomy in pediatric groups.
Methods: Four adolescents with juvenile myasthenia gravis all underwent hybrid combination of small subxiphoid incision and thoracoscopic thymectomy at our institute. Clinical characteristics and surgical outcome were consecutively collected.
Results: In these 4 patients, 2 presented with Osserman class III and 2 with class IIb. The mean operative time was 180 minutes. There was no conversion to sternotomy, and there was only minimal blood loss. Follow-up duration was 3 to 64 months. Postoperatively, 1 patient had complete remission and 3 patients had improvement in clinical symptoms.
Conclusion: Hybrid combination of small subxiphoid incision and thoracoscopic thymectomy may be an effective alternative with low surgical invasiveness for treating juvenile myasthenia gravis.

Lupus and inflammatory bowel disease share a common set of microbiome features distinct from other autoimmune disorders.

Objectives: This study aims to elucidate the microbial signatures associated with autoimmune diseases, particularly systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD), compared with colorectal cancer (CRC), to identify unique biomarkers and shared microbial mechanisms that could inform specific treatment protocols.
Methods: We analysed metagenomic datasets from patient cohorts with six autoimmune conditions-SLE, IBD, multiple sclerosis, myasthenia gravis, Graves' disease and ankylosing spondylitis-contrasting these with CRC metagenomes to delineate disease-specific microbial profiles. The study focused on identifying predictive biomarkers from species profiles and functional genes, integrating protein-protein interaction analyses to explore effector-like proteins and their targets in key signalling pathways.
Case report: Efgartigimod is a novel therapeutic option for ocular myasthenia gravis: a report of 2 cases.

Introduction: Efgartigimod has been approved for the treatment of acetylcholine receptor antibodies-positive generalized myasthenia gravis (AChR-Ab+gMG), but its efficacy in patients with ocular myasthenia gravis (OMG) is not known.
Case Presentation: We describe 2 cases of patients with AChR-Ab+ OMG who showed unfavorable responses to corticosteroids and tacrolimus. Within 2 weeks of initiating efgartigimod, both patients showed rapid improvement and minimal symptom expression was achieved in weeks 3 to 4, which was maintained up to week 12.

Objective: This study aims to delineate the clinical features underlying the concurrent disease of neuromyelitis optica spectrum disorder (NMOSD) and myasthenia gravis (MG), and to identify efficacious therapeutic strategies.
Background: NMOSD and MG are uncommon autoimmune diseases that infrequently co-exist. Despite previous reports, a consensus on treating NMOSD concurrent with MG is lacking.
