Ophthalmoparesis as an unusual manifestation of anti-3‑hydroxy-3-methyl-glutaryl-coenzyme A reductase antibody-associated myopathies.

We describe two anti-3‑hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR) antibody-positive patients with treatment-responsive ophthalmoparesis. Patient 1 was a 53-year-old male with progressive proximal limb weakness, dysphagia, ptosis, and diplopia over 6 weeks and creatine kinase (CK) of 3,512 units/L. Patient 2 was a 55-year-old female with progressive proximal weakness, dysarthria, ptosis, diplopia, and dyspnea over 2 weeks with CK of 31,998 units/L.

Trajectory of left ventricular ejection fraction in response to therapies in patients with muscular dystrophy.

Background: Patients with muscular dystrophy (MD) are at elevated risk of serious cardiac complications and clinical assessment is limited due to inherent physical limitations. We assessed the utility of left ventricular ejection fraction (LVEF) derived from transthoracic echocardiogram (TTE) as a prognostic marker for major adverse cardiac events (MACE) in a mixed adult MD cohort.

Methods: One hundred and sixty-five MD patients (median age: 36 (interquartile range [IQR]: 23.

Low Prevalence of Cardiomyopathy in Patients with Mitochondrial Disease and Neurological Manifestations.

Patients with mitochondrial diseases can develop cardiomyopathy but with variable expressivity and penetrance. Our prospective study enrolled and evaluated a cohort of 53 patients diagnosed with chronic progressive ophthalmoplegia (CPEO, = 34), Kearns-Sayre syndrome (KSS, = 3), neuropathy ataxia and retinitis pigmentosa (NARP, = 1), myoclonic epilepsy with ragged red fibers (MERRF, = 1), Harel-Yoon Syndrome (HYS, = 1) and 13 patients with undefined mitochondrial diseases, presenting primarily with neurological symptoms. Over a 4-year period, six patients in our study cohort were diagnosed with heart disease (11.

Therapeutic and Diagnostic Challenges in Myasthenia Gravis.

"Myasthenia gravis (MG) is the most common autoimmune neuromuscular disorder. This article highlights several cases that the practicing neurologist may encounter in the treatment of MG. Diagnostic uncertainty continues to be an issue in patients who are seronegative to the 2 most common antibodies, acetylcholine receptor and muscle-specific tyrosine kinase (MuSK).

Detecting subtle fingertip sensory and motor dysfunction in adults with type II diabetes.

Although evidence has emerged regarding functional neural impairment of all four limbs with a diagnosis of type II diabetes (T2D), there is conflicting evidence regarding impairment in manual function with the disease. The purpose of the current study was to evaluate hand/fingertip function in T2D as compared to healthy age- and gender-matched controls. Ten adults with T2D and ten healthy age- and gender-matched control subjects underwent a battery of clinically validated and laboratory-based evaluations of sensory function, motor function, and quality of life evaluation.

Amyotrophic lateral sclerosis with positive anti-acetylcholine receptor antibodies. Case report and review of the literature.

Myasthenia gravis is a nerve-muscle junction disease, for which the most specific test is an increase in the anti-acetylcholine receptor antibodies (anti-AChR-Abs) titer. Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting both upper and lower motor neurons. Positive AChR-Ab in patients with pure ALS are exceedingly rare.

Mutilating acral ulcers: the spectrum of differential diagnosis.

Prominent acral mutilating ulcers can be present in sensorimotor neuropathies. Although diabetes mellitus is the most common cause of neuropathic ulcers, these skin lesions may manifest in nondiabetic neuropathies. The dermatologic abnormalities may even precede the onset of typical neuropathic symptoms, leading to diagnostic confusion.
