Intravenous immunoglobulin (IVIg) has been proven beneficial in myasthenic crisis, but their role as maintenance therapy is unclear. The aim of this study was to determine if maintenance therapy with low-dose IVIg improves clinical outcome and may be used as a steroid-sparing agent in myasthenia gravis (MG). We retrospectively reviewed charts of all MG patients treated with IVIg from January 2006 to December 2019. Long-term treatment response to IVIg was assessed by improvement in the Myasthenia Gravis Foundation of America (MGFA) clinical classification scale as primary end point, as well as the ability to reduce the time-weighted average required dose of prednisone as secondary end-point, in a follow-up period of 36months. 109 patients were treated with IVIg. The mean follow-up time was 34.03 ± 5.5months. Sixty-seven patients (61.4%) responded to therapy with at least one-point improvement of the MGFA scale. There was no statistical difference in demographic and clinical characteristics between IVIg responders and non-responders. The mean prednisone dose decreased significantly from 33.1 ± 14.5mg at baseline to 7.2 ± 7.8mg after 36months of IVIg treatment (P < 0.0001), with the greatest effect after 6months (33.1 ± 14.5mg Vs. 17.9 ± 11.7mg; P < 0.0001). In the follow-up period of 36months, most patients (92.5%) remained clinically and pharmacologically stable under chronic IVIg treatment. This retrospective study demonstrates that chronic low-dose IVIg treatment in patients with MG improves clinical outcomes and has a prolonged and significant steroid-sparing effect over a period of 3years.This retrospective study demonstrates that chronic low-dose IVIg treatment in patients with MG improves clinical outcomes and has a prolonged and significant steroid-sparing effect over a period of 3 years. In multiple sclerosis (MS), pronounced neurodegeneration manifests itself as cerebral gray matter (GM) atrophy, which is associated with cognitive and physical impairments. GDC-0980 Microstructural changes in GM estimated by diffusion kurtosis imaging (DKI) may reveal neurodegeneration that is undetectable by conventional structural MRI and thus serve as a more sensitive marker of disease progression. The primary objective was to investigate the relationships between morphological and diffusional properties in cerebral GM and physical and cognitive performance in relapsing-remitting MS (RRMS) patients. A secondary objective was to investigate the relationship between GM microstructure and white matter (WM) injury, estimated by the volume of WM lesions. Sixty-seven RRMS patients performed the brief repeatable battery of neuropsychological tests (BRB-N), the 6-minute walk test (6MWT), the six spot step test (SSST), and underwent MRI scans using structural and DKI protocols. GM volumetrics and DKI measurements were analyzed in the cortex and deep GM structures using a general linear model with demographics, physical- and cognitive performance as covariates. Mean diffusivity (MD) in the cortex was associated with the SSST, 6MWT, information processing, global cognitive performance, and volume of WM lesions. In addition, thalamic volume was associated with SSST (r  = 0.21, 6MWT (r  = 0.18), information processing (r  = 0.21), and WM lesion volume (r  = 0.60). Cortical diffusion and thalamic volume are associated with walking and cognitive performance in RRMS patients and are highly affected by the presence of WM lesions.Cortical diffusion and thalamic volume are associated with walking and cognitive performance in RRMS patients and are highly affected by the presence of WM lesions.To evaluate clinical and ultrasonographic efficacy of high-intensity laser therapy (HILT) in patients with hemiplegic shoulder pain (HSP) accompanied by partial thickness rotator cuff tear (PTRCT). The study was designed as a prospective, randomized, controlled trial. Patients with HSP accompanied by PTRCT (n = 44) were randomly assigned to HILT and control groups. Both groups were treated with a multidisciplinary stroke rehabilitation and a therapeutic exercise program to the affected shoulder supervised by physiotherapists. In addition, HILT group received 3 sessions of the intervention per week for 3 weeks. Primary outcome measure was visual analogue scale (VAS) for pain. Secondary outcome measures were range of motion (ROM) of the shoulder joint, Shoulder Pain and Disability Index (SPADI), Brunnstrom Recovery Stage (BRS), Modified Ashworth Scale (MAS), Nottingham Health Profile (NHP), Functional Independence Measure (FIM), and ultrasonographic PTRCT size. Participants were assessed at pre- and post-treatment. A total of 41 patients completed the study. A statistically significant improvement was observed in VAS, ROM, FIM, SPADI, NHP, and PTRCT parameters in HILT group at post-treatment compared to pre-treatment (all P less then 0.05). However, control group indicated significant improvement only in VAS, ROM, and SPADI parameters (all P less then 0.05). When differences in clinical parameters at pre- and post-treatment assessment were compared between two groups, change in VAS, FIM, BRS, SPADI, NHP, and PTRCT in HILT group was significantly better than control group (all P less then 0.05). HILT combined with therapeutic exercise seems to be clinically and ultrasonographically more effective in the treatment of patients with HSP accompanied by PTRCT than therapeutic exercise alone in the short term. Further studies are needed with long-term follow-up. CinicalTrials.gov Identifier NCT04669405. Ground glass opacity (GGO) nodules were found incidentally by computed tomography (CT) scan in some teenagers, which turned out to be lung cancer. The purpose of this study is to summarize the characteristics of teenage patients with GGO featured lung adenocarcinoma. Patients aging from 13 to 20 who were incidentally diagnosed with lung cancer were reviewed between February 2015 to December 2020. The clinical, radiological and pathological characteristics were analyzed. Totally 12 patients were included. All of them were diagnosed as GGO featured lung cancer through CT scan, with no presenting symptom. The median surveillance before surgery was 5.5months, and none of these GGO lesions enlarged or altered in the property during the surveillance. The mean tumor diameter was 0.93 ± 0.25cm. Ten patients underwent wedge resection by video-assisted thoracoscopic surgery (VATS), 9 of which were minimally invasive adenocarcinoma (MIA) and 1 of which were invasive adenocarcinoma (IAC) in the pathological analysis.
