A Preliminary Videofluoroscopic Investigation of Swallowing Physiology and Function in Individuals with Oculopharyngeal Muscular Dystrophy (OPMD)

This study sought to describe the pathophysiology of dysphagia in a small sample of patients with OPMD using a videofluoroscopy examination (VFSS) involving 3  × 5 mL boluses of thin liquid barium (22% w/v). The aim of this study is to extend what is known about the pathophysiology of dysphagia in OPMD, by quantifying changes in swallow timing, kinematics, safety, and efficiency, measured from VFSS. This study is a secondary analysis of baseline VF SS collected from 11 adults (4 male), aged 48–62 (mean 57) enrolled in an industry-sponsored phase 2 therapeutic drug trial. Blinded raters scored the VFSS recordings for safety [Penetration-Aspiration Scale (PAS)], efficiency [Normalized Residue Ratio Scale (NRRS)], timing [Pharyngeal Transit Tim e (PTT), Swallow Reaction Time (SRT), Laryngeal Vestibule Closure Reaction Time (LVCrt), Upper Esophageal Sphincter Opening Duration (UESD)], and kinematics (hyoid movement, pharyngeal constriction, UES opening width). Impairment thresholds from existing literature were defined to characterize swall owing physiology and function. Further, Fisher’s Exact tests and Pearson’s correlations were used to conduct a preliminary exploration of associations between swallowing physiology (e.g., kinematics, timing) and function (i.e., safety, efficiency). Compared to published norms, we identified sign ificant differences in the degree of maximum pharyngeal constriction, hyoid movement distance and spee...

AbstractThree-dimensional (3D) speckle-tracking echocardiography (STE) is a new imaging modality used for quantitative analysis of left ventricular (LV) function. The aim of this study is to assess the value of 3D STE in early detection of subclinical myocardial involvement in children with Duchenne muscular dystrophy (DMD). Fifty-six children with DMD (mean age, 8.8  ± 1.9 years) and 31 age-matched control subjects were studied. Patients were subdivided into two groups by age: ≤ 8 or>  8 years. Standard echocardiography examinations were performed to measure LV size and e...

This 70 year old man in routine check up showed up this ECG. What is it ? a  quick debate ensued ! Is this RVH RBBB Or Both ? Neither RBBB nor RVH Wrong lead placement Is it a normal ECG after all ? I thought it was RVH. (do considered RBBB) but since lead V 2 showed tall R , I was more than sure RVH was likely . Many voted for RBBB. .Some others said RBBB can never occur in monophasic form.I said it’s possible. Some body challenged me without Echo Imaging a  monophasic RBBB can never be differentiated from RVH. After a mini argument I reluctantly agreed.Yes, it seemed there is no way to differentia...

Mark McQuain has raised the persistent, vexing issue of the pricing of drugs for rare diseases—in the case at hand, Sarepta’s eteplirsen (Exondys 51) for Duchenne Muscular Dystrophy, the disease over which the late comedian Jerry Lewis lost sleep every Labor Day weekend for years. Mark provided an excellent summary (he calls it “crude,” but … Continue reading "Mumbling orphans—a bit more"

Fukuyama congenital muscular dystrophy (FCMD), an autosomal recessive disorder characterized by the combination of severe muscular dystrophy and dysgenesis of the eye and central nervous system which causes intellectual deficits and epilepsy, was first reported by Fukuyama et  al. in 1960 [1, 2]. FCMD is the second most prevalent of the Japanese childhood-onset muscular dystrophies after Duchenne muscular dystrophy (DMD), but it is rarely reported outside of Japan. The annual incidence was previously reported to be 2.9 per 100,000 live births [3, 4].

Duchenne muscular dystrophy (DMD) is an X-linked progressive myopathy due to mutations in the dystrophin gene, affecting one in every 3 ’600–10’000 live male births [1,2]. Boys with DMD typically present with delayed motor milestones and muscle weakness, they progress to loss of ambulation around their teens, and respiratory and heart failure during the second decade. Corticosteroids remain the standard supportive therapy for DMD even though new treatments recently emerged [3–6]. Along with other risk factors that are present in DMD such as progressive weakness, immobility and delayed puberty, chron...

Authors: Angelini C, Giaretta L, Marozzo R Abstract INTRODUCTION: Limb Girdle Muscular Dystrophies (LGMD) encompasses a clinically heterogeneous group of rare, genetic progressive muscle disorders presenting with weakness and atrophy of predominant pelvic and shoulder muscles. The spectrum of disease severity ranges from severe childhood-onset muscular dystrophy to adult-onset dystrophy. Areas covered: The review presents an update of the clinical phenotypes and diagnostic options for LGMD including both dominant and recessive LGMD and consider their differential clinical and histopathological features. An overview of...

By Mark McQuain In my previous blog entry, I crudely summarized the genetic basis for Duchenne Muscular Dystrophy (DMD) and one pharmaceutical company’s (Sarepta) current effort to research, manufacture and finance a genetic treatment that increases the production of a muscle protein missing in patients with DMD called dystrophin.
