Six patients are described in whom facial diplegia occurred in the first year of life, with subsequent development of facioscapulohumeral dystrophy. All had severe progressive disability prior to adolescence. Facial involvement did not include extraocular muscles. All six patients had a sensorineural hearing loss. Evidence of a mildly affected parent was found in three families. Progressive and severe facioscapulohumeral dystrophy accompanied by facial diplegia and sensorineural hearing loss may represent a separate genetic form of facioscapulohumeral dystrophy.

Background And Aims: Body composition parameters associated with aerobic fitness, mirrored by maximal oxygen consumption (V̇Omax), have recently gained interest as indicators of physical efficiency in facioscapulohumeral dystrophy (FSHD). Bioimpedance analysis (BIA) allows a noninvasive and repeatable estimate of body composition but is based on the use of predictive equations which, if used in cohorts with different characteristics from those for which the equation was originally formulated, could give biased results. Instead, the phase angle (PhA), a BIA raw bioelectrical parameter reflecting body fluids distribution, could provide reliable data for such analysis.

DUX4 is typically a repressed transcription factor, but its aberrant activation in Facioscapulohumeral Muscular Dystrophy (FSHD) leads to cell death by disrupting muscle homeostasis. This disruption affects crucial processes such as myogenesis, sarcolemma integrity, gene regulation, oxidative stress, immune response, and many other biological pathways. Notably, these disrupted processes have been associated, in other pathological contexts, with the presence of connexin (Cx) hemichannels-transmembrane structures that mediate communication between the intracellular and extracellular environments.

A 44-year-old man with a history of facioscapulohumeral muscular dystrophy and pectus excavatum presented with multiyear history of progressive, severe respiratory dysfunction, pain, recurrent respiratory infection, and chest wall deformity. With bioprosthetic engineers, the surgical team customized a 3-dimensional printed model of a sternal implant interacting with the patient's anatomy. After approval from the Food and Drug Administration, the customized sternal plates were created and implanted in a sternal reconstruction operation.

Facioscapulohumeral dystrophy type 1 (FSHD1) displays prominent intra- and interfamilial variability, which complicates the phenotype-genotype correlation. In this retrospective study, we investigated FSHD1 patients classified as category D according to the Comprehensive Clinical Evaluation Form (CCEF), a category defined by FSHD patients showing uncommon clinical features, to identify genetic causes explaining these uncommon phenotypes. Demographics, clinical data and clinical scales of FSHD1 patients were retrospectively evaluated.
