The association of epidermolysis bullosa simplex and muscular dystrophy (EBS-MD) has rarely been discussed in ophthalmology literature. This case report offers a brief summary of epidermolysis bullosa and describes what is known about EBS-MD. The case involves a patient with EBS-MD who presented with ptosis and ophthalmoplegia, suggesting that these may be complications of EBS-MD.

Myotonic dystrophy (DM1) is the most prevalent muscular dystrophy occurring in adulthood. DM1 is a multi-systemic disorder resulting in early-onset cataracts, cardiac rhythm problems, muscle weakness, ptosis, and cognitive and psychiatric manifestations. Dysphagia is one of the most problematic symptoms of DM1 because it may cause weight loss, aspiration pneumonias or sudden death. The purpose of this review is to describe the characteristics of DM1 that make dysphagia management problematic, and to address the need for disease-specific guidelines and a clinical tool to aid in diagnosing and managing dysphagia in this population.

Epidermolysis bullosa associated with muscular dystrophy is a rare, autosomal recessive form of epidermolysis bullosa simplex caused by mutations in the plectin gene, PLEC1. We describe a phenotypically mild case due to compound heterozygous mutations in PLEC1 (2677_2685del and the novel mutation Q1644X). Clinical features included mild skin blistering since birth, slowly progressive and late-onset upper limb-predominant weakness, facial weakness, ptosis, incomplete ophthalmoplegia, and paroxysmal atrial fibrillation.

Myotonic Dystrophy Type 1 (DM1) is the most common worldwide autosomal dominant muscular dystrophy due to polynucleotide [CTG]( n ) triplet expansion located on the 3'UTR of chromosome 19q13.3. A toxic gain-of-function of abnormally stored RNA in the nuclei of affected cells is assumed to be responsible for several clinical features of the disease. It plays a basic role in deregulating RNA binding protein levels and in several mRNA splicing processes of several genes, thus leading to the multisystemic features typical of DM1. In DM1, the musculoskeletal apparatus, heart, brain, eye, endocrine, respiratory and gastroenteric systems are involved with variable levels of severity. DM1 onset can be congenital, juvenile, adult or late. DM1 can be diagnosed on the grounds of clinical presentation (distal muscular atrophy and weakness, grip and percussion myotonia, ptosis, hatchet face, slurred speech, rhinolalia), EMG myotonic pattern, EKG (such as AV-blocks) or routine blood test abnormalities (such as increased CK values or hypogamma-globulinemia) and history of cataract. Its confirmation can come by DNA analysis. At present, only symptomatic therapy is possible and is addressed at correcting hormonal and glycemic balance, removing cataract, preventing respiratory failure and, above all, major cardiac disturbances. Efficacious therapies targeted at the pathogenic mechanism of DM1 are not yet available, while studies that seek to block toxic RNA intranuclear storage with specific molecules are still ongoing.

Myotonic dystrophy is the most common autosomal dominant myopathy in adults. Our patient, a 41 year-old female suffering from myotonic muscular dystrophy, developed upper thoracic myelopathy due to hypertrophy of the ligamentum flavum and the posterior longitudinal ligament. She had a typical hatchet face and ptosis with "head hanging forward" appearance caused by neck weakness. Motor weakness, sensory changes and severe pain below T4 level, along with urinary incontinence began 3 months ago. Genetic and electrodiagnostic studies revealed myotonic dystrophy type 1. Magnetic resonance imaging of the spine showed loss of cervical lordosis and spinal cord compression due to hypertrophied ligamentum flavum and posterior longitudinal ligament at T1 to T3 level. We concluded that her upper thoracic myelopathy was likely related to the thickness of the ligamentum flavum and posterior longitudinal ligament due to repetitive mechanical stress on her neck caused by neck muscle weakness with myotonic dystrophy.

Plectin mutations have been reported in epidermolysis bullosa simplex with muscular dystrophy. We report the first case of left ventricular non-compaction in an 18-year-old male with epidermolysis bullosa simplex with muscular dystrophy. The patient was diagnosed with epidermolysis bullosa simplex after blistering was noted at birth. Motor function difficulties were first recognized at age 11, however the patient was lost to follow up. He was re-evaluated at age 17 and demonstrated significant ptosis, ophthalmoparesis, and pharyngeal muscle weakness. He had predominant proximal muscle weakness with the inability to raise arms against gravity. He was ambulatory for short distances but lost the ability to rise from the floor at 14 years. He was subsequently diagnosed with epidermyolysis bullosa simplex with muscular dystrophy and a PLEC1 mutation. Screening cardiovascular imaging revealed a diagnosis of isolated left ventricular non-compaction. This case highlights the potential for delayed onset muscular dystrophy in patients with epidermolysis bullosa simplex. Furthermore, this case also underscores the importance of long term, routine cardiac evaluation, including imaging and electrophysiologic evaluation, in patients with epidermolysis bullosa simplex with muscular dystrophy as the cardiac phenotype appears to parallel the variable severity and age of onset that characterize the neuromuscular phenotype.

Oculopharyngeal muscular dystrophy (OPMD) is a rare cause for late-onset dysphagia. OPMD normally follows an autosomal dominant inheritance. Herein we describe a rare case of an autosomal recessive inheritance of OPMD. An 80-year-old male presented with progressive dysphagia, frequent aspiration and change of voice getting inarticulate and hoarse. Physical examination showed ptosis of the right eyelid. Endoscopic and manometric investigation revealed a nonspecific motility disorder with hypopharyngeal esophageal hypotension. The severity of dysphagia became apparent when significant aspiration occurred during a barium swallow. Magnetic resonance imaging of the head ruled out a malignant or cerebral ischemic process. Based on the neurological examination, neurogenic muscular dystrophy was suspected and DNA analysis was performed. The analysis confirmed the extremely rare diagnosis of an autosomal recessive inheritance pattern of OPMD with homozygous (GCN)6(GCN)4(GCN) expansion of the poly-(A) binding protein nuclear 1 gene. As OPMD normally follows an autosomal dominant inheritance, consanguinity of the patient's parents was suspected.

Muscular dystrophy encompasses a group of disorders characterized by the progressive weakness of the skeletal muscles. These disorders are mostly inherited and have characteristic age and muscle group predilection. Lingual muscle involvement is an unusual feature in patients with the muscular dystrophy and helps in the differential diagnosis. We recently encountered a serving soldier presenting with complaints of bilateral ptosis and dysphagia of 5 years duration. Examination showed bilateral ptosis, percussion myotonia, generalized muscular atrophy including that of tongue muscles, and a characteristic hatchet facies. Investigations revealed elevated creatine kinase and myotonic discharges on electromyography leading to a diagnosis of myotonic dystrophy type 1. Muscular dystrophy has a varied presentation and can pose a diagnostic problem in clinical practice. We present the case to highlight the differential diagnosis of tongue atrophy in patients with muscular dystrophy.

Thirty five floppy children seen during two year period, were subjected to clinical examination, electroneuromyography and muscle biopsy. The muscle biopsy was sent for routine histology, histochemistry and electron microscopy. Using muscle pathology as the 'gold standard' for diagnosis, the aetiological entities were spinal muscular atrophy (16), congenital muscular dystrophy (6), mitochondrial myopathy (3), congenital fibre type disproportion (2), acid mutase deficiency (1) and benign congenital hypotonia (6). Mental subnormality, seizures, ptosis and ophthalmoplegia suggested mitochondrial disease (n=2). Macroglossia, hepatomegaly and cardiomegaly along with the dive bomber effect on electromyography were useful clues to the diagnosis of Pompe's disease (n=1). Positive decremental test established the diagnosis of congenital myasthenia in one patient. Contrary to most previously published reports, infantile onset of spinal muscular atrophy did not always spell a poor prognosis on follow up. 'Floppy infant syndrome' has varied etiology. Comprehensive evaluation including clinical, electrophysiological and detailed histological examination is necessary for proper diagnosis and prognosis of this heterogenous entity.

Oculomotor dysfunction in epidermolysis bullosa simplex associated with muscular dystrophy has been reported rarely in the ophthalmic literature. In a series of 6 patients with epidermolysis bullosa simplex associated with muscular dystrophy, 3 demonstrated ptosis, ophthalmoplegia, or both. Ptosis and ophthalmoplegia may occur early in epidermolysis bullosa simplex associated with muscular dystrophy and aid in diagnosis. [J Pediatr Ophthalmol Strabismus. 2018;55:e26-e29.].
