We hereby reported a case of 60-year old man with superficial esophageal cancer complicated with idiopathic muscular hypertrophy of the esophagus. Endoscopic ultrasonography and CT showed the thickness of esophageal muscular layer, but the accurate diagnosis could not be entertained before operation. Idiopathic muscular hypertrophy of the esophagus is an entity rarely encountered, and most cases are diagnosed at postmortem examination. Only a few cases have been reported regarding its clinical symptoms and images. The etiology remains to be elucidated, and the pathologic features are characterized by significant thickness of inner circular muscular layer of esophagus without degeneration of plexus and ganglionic cells. This case report deals with superficial esophageal cancer complicated with idiopathic muscular hypertrophy of esophagus. Literature review is also included.

One is not like the other: health quality of life scores vary in neuromuscular EOS by diagnosis.

Purpose: The etiology of early-onset scoliosis (EOS) has been shown to significantly influence baseline parent-reported health-related quality of life (HrQOL). In combining these etiology groups, we obligatorily lump together many disparate diagnoses, particularly true in the neuromuscular (NM) cohort. We sought to evaluate the influence of underlying neuromuscular diagnosis on the HrQOL at 5 years following surgery for EOS.

Severe early-onset scoliosis (EOS) can be addressed by different growth-friendly approaches, although the indications of each technique remain controversial. The aim of this study was to compare, in a large series of patients, the potential and limitations of the different distraction-based surgical techniques to establish the most suitable surgical approach to treat EOS. We conducted a retrospective observational cohort study evaluating 62 EOS cases treated between January 2002 and December 2021 with a traditional growing rod (TGR), a magnetically controlled growing rod (MCGR) and vertical expandable prosthesis titanium ribs (VEPTR) at IRCSS Istituto Ortopedico Rizzoli, Bologna, Italy.

Objective: To evaluate the main outcomes of disease activity and their association with other measures of activity, damage, and quality of life in patients with idiopathic inflammatory myopathy (IIM) according to time since diagnosis and positivity to antisynthetase autoantibodies (ASAs).
Methods: Cross-sectional multicenter study within the Spanish Myo-Spain registry. Cases were classified as incident (≤ 12 months since diagnosis) and prevalent.
Histone Deacetylase (HDAC) Inhibitors as a Novel Therapeutic Option Against Fibrotic and Inflammatory Diseases.

Histone deacetylases (HDACs) are enzymes that play an essential role in the onset and progression of cancer. As a consequence, a variety of HDAC inhibitors (HDACis) have been developed as potent anticancer agents, several of which have been approved by the FDA for cancer treatment. However, recent accumulated research results have suggested that HDACs are also involved in several other pathophysiological conditions, such as fibrotic, inflammatory, neurodegenerative, and autoimmune diseases.

Article Synopsis
- The study investigates inclusion body myositis (IBM), focusing on the role of TDP-43 protein and its implications in muscle pathology.
- It found that cryptic peptides linked to TDP-43 were present in 65% of muscle biopsies from IBM patients, but absent in other controls, indicating potential as a biomarker for IBM.
- The findings suggest that restoring TDP-43 function might help slow down muscle degeneration in patients with this disease.
