Hereditary motor neuropathies (HMN) comprise a broad genotypic and phenotypic spectrum of rare, progressively disabling diseases manifesting with length-dependent muscle weakness and atrophy. To date, more than half of the cases cannot be genetically explained. To provide symptomatic and disease-modifying treatments in the future, a better understanding of disease mechanisms is required.
By whole exome and genome sequencing, the discovery of several novel genes (SCO2, TDRKH, SPTAN1, CADM3, and SORD) involved in the pathogenesis of HMN has now relevantly changed the pathophysiological knowledge. This recent success in causative understanding has mainly been driven by the development of functional models including cell culture, animal, and patient-derived induced pluripotent stem cell platforms. These models have an important impact on therapeutic advances including broader approaches to prevent or reverse axonal degeneration and individualized gene silencing attempts using sequence-specific RNA degradation mechanisms.
In rare diseases such as HMN, the recent development of genetic sequencing and data interpretation methods has enabled a broader diagnostic approach, whereas treatment strategies are becoming more individualized. Significant milestones have been reached in the discovery of new genes, the establishment of functional disease models, and the preclinical development of mechanistic-based therapies.

Yet methods to activate and expand these cells are limited, often pose challenges to automation, and have biological limitations impacting the output of the injectable dose. This study describes the development of a novel, highly flexible, soluble DNA-based T-cell activation and expansion platform which alleviates the limitations of current technologies and provides rapid T-cell activation and expansion.Checkpoint inhibitors (CPIs) have demonstrated a heterogenous spectrum of response and disease progression that may not be fully captured by conventional response criteria, such as a limited degree of progression, known as oligoprogression, which could benefit from local treatment. We retrospectively analyzed data from all patients diagnosed with metastatic melanoma, who received CPI between January 2006 and March 2018 at Royal Marsden. https://www.selleckchem.com/products/prgl493.html We enrolled 36 patients who experienced progression in a maximum of 3 metastatic sites, after achieving disease control from therapy with CPI, and were radically treated with the locoregional approach. We carried out Kaplan-Meier analysis to obtain progression free-survival post-first oligoprogression (PFS-PO1), overall survival (OS) post-first oligoprogression, and OS estimates. The median time to oligoprogression from the start of CPI was 12 months. At a median follow-up of 34 months, the median PFS-PO1 was 32 months, with 50% of patients not progressed at the time of the data cutoff. The median OS-post-first oligoprogression was not reached. At a median follow-up of 52 months (from the first cycle of CPI), the median OS was not reached, with 75% of patients alive at the time of analysis. Univariate and multivariate analyses demonstrated that baseline American Joint Committee on Cancer stage IV M1a or M1b is associated with a longer PFS-PO1 compared with stage M1c or M1d. We observed that local therapy for oligoprogression after CPI can result in durable disease control, suggesting that locoregional treatment should be considered in patients being treated with immunotherapy. However, prospective evaluation, perhaps in randomized trials, is needed.
The purpose of this study was to evaluate and compare the 5-year efficacy and safety of accelerated transepithelial (A-epi-on) corneal collagen cross-linking (CXL) with standard CXL (epi-off) in children with progressive keratoconus (KC).
This prospective cohort study included 78 eyes of patients aged 18 years old or younger with progressive KC who underwent CXL at the Oftalmosalud Institute of Eyes, Lima, Peru. A-epi-on CXL was performed in 32 eyes (30' of impregnation/5' of irradiation at 18 mW/cm2) and epi-off CXL was performed in 46 eyes (30'of impregnation/30' minutes of irradiation at 3 mW/cm2). Visual acuity, refraction, and the Scheimpflug imaging parameters were evaluated preoperatively and postoperatively at 1 and 5 years.
The best corrected visual acuity improved to 0.06 logarithm of the minimum angle of resolution (SD 0.19, P = 0.03) and 0.09 logarithm of the minimum angle of resolution (SD 0.13, P < 0.001) in the A-epi-on and epi-off groups, respectively. The mean flattening in the mean keratometry was 0.09 diopters (D) (SD 0.68, P = 0.33) and 3.18 D (SD 5.17, P < 0.001) in the A-epi-on CXL and Epi-off groups at the 5-year follow-up. Significant differences were found in the change at 1 and 5 years between the groups for cylinder reduction, flat and mean K, and pachymetry (all P < 0.05). The KC progression rate was 9.37% (3/32) in the A-epi-on CXL; no progression was found in the epi-off CXL group at the 5-year follow-up.
Both procedures halted the progression of KC at the 5-year follow-up; however, epi-off CXL was safer and more effective when compared with A-epi-on CXL.

The current article reviews literature on the contemporary management of superior semicircular canal dehiscence syndrome (SSCDS). Approaches to management and surgical techniques are compared along with a discussion of the use of more standardized, objective outcome measures.
Considerable debate still exists as to what approach and technique is most appropriate for patients with SSCDS and how to best measure postoperative outcomes. However, it is increasingly accepted that multiple factors account for outcomes in SSCDS, including presenting symptoms and presence of vestibular comorbidities. Therefore, surgical intervention is best tailored to each individual patient. Data on SSCDS outcomes is heterogenous, and increased emphasis is being placed on validated measures of outcome. Round window approaches remain controversial and their role is still undefined.
The treatment strategies for SSCDS continue to diversify. A patient-specific approach with systematic documentation of outcomes will continue to inform how these patients are best managed.
