In order to investigate the pathological basis of muscle hypertrophy in Duchenne dystrophy, 9 biopsy specimens of the lateral gastrocnemius and 7 of the vastus lateralis were compared. Myotonic dystrophy can appear at any time between birth and old age. Scapular winging is more common in LGMD2C-2F than in Duchenne muscular dystrophy. cle weakness, calf hypertrophy, muscle atrophy, and con-tractures with orthopedic deformities occur (Swaminathan et al., 2009). At the 229th ENMC international workshop, limb-girdle muscular dystrophy was defined as 'a genetically inherited condition that primarily affects skeletal muscle leading to progressive, predominantly proximal muscle weakness at presentation caused by a loss of muscle fibres. Eventually, all the muscles are affected. Calf muscle pseudohypertrophy (enlarged calves)- In Duchene muscular dystrophy (DMD), the muscles waste away and are replaced by fat and scar tissue - a process termed as fibrosis. Valley Sign in Duchenne Muscular Dystrophy : Importance in Patients with Inconspicuous Calves S. Pradhan Department of Neurology Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow - 226 014, India. Some patients may have calf hypertrophy. Acronym. Lumbar Hyperlordosis. Creatine kinase (CK): CK is an enzyme found in muscle and is raised in the muscular dystrophies: usually to level of several thousand. This enlargement of the calf muscles is called pseudohypertrophyö and is due mainly to an increase in fatty tissue in the muscle. Figure 1. Muscle loss typically occurs first in the thighs and pelvis followed by the arms. Muscle hypertrophy can exaggerate postural instability and joint contractures. Congenital muscular dystrophy associated with calf hypertrophy, microcephaly and severe mental retardation in three Italian families: evidence for a novel CMD syndrome.

A 4-year-old boy presents with a history of ambulation delayed until 18 months of age, toe walking, calf hypertrophy, and proximal hip girdle muscle weakness. Calf hypertrophy is a common feature in Becker muscular dystrophy (BMD), and it is still debated to which extent fatty degeneration or true muscle hypertrophy account for it. Patients usually become wheelchair-bound by the age of 12 years, and die of cardiorespiratory complications in their late teens to early twenties. We wanted to investigate the relative contribution of these two components using a simple image analysis approach and their possible correlation with disease severity. Summary Several patients of Duchenne muscular dystrophy (DMD) do not demonstrate clinically remarkable calf hypertrophy. Cranial nerve examination was unremarkable, and there were no apparent signs of either upper or lower motor lesions (Figures 1‐3-1‐3). The patients' ages ranged from 4 to 11 years. In some cases, the breathing problems are severe … Figure 2. In Duchenne muscular dystrophy (DMD), this selectivity is evident for hypertrophy as well as wasting. In particular, early-onset and late-onset cases are not uncommon, and the severity and sequence of involvement of different muscle groups may vary. Some types are also associated with problems in other organs. Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy that primarily affects boys. Most are unable to walk by the age of 12. Overgrowth (hypertrophy) of the calf muscles occurs in some people with limb-girdle muscular dystrophy.Weakening of the heart muscle (cardiomyopathy) occurs in some forms of limb-girdle muscular dystrophy. The selective muscular involvement extended to different heads of the deltoid and quadriceps, which showed concomitant atrophy and hypertrophy. hypertrophy, diaphragmatic weakness, and/or variable cardiac abnormalities.. Calf hypertrophy affects some patients. Only one year old patient was asymptomatic however, he has a family history of DMD. Muscular dystrophy Gene/proteins affected Gene location Inheritance Prevalence Age at diagnosis/symptom onset (y) Typical presenting symptom; 1: Duchenne: Dystrophin: Xp21.1: X-linked recessive: 1/3,500 (males) <5: Muscle weakness, difficult ambulation, calf hypertrophy: 2: Becker: Dystrophin: Xp21.1: X-linked recessive: 1/33,000 (males) 10–50 Selective muscle involvement is an important characteristic of muscular dystrophies. Duchenne muscular dystrophy (DMD) is an early‐onset, ... calf hypertrophy, flat feet (pes planus), and positive Gowers’ sign. Patients with a late onset tend to have a more slowly progressive course. Absent type 2B muscle fibers Muscular dystrophy Fatty replacement of muscle Duchenne & Becker dystrophies. of muscle mass, but also less commonly in the arms, neck and other areas; » muscle wasting, calf muscle hypertrophy, lordosis and contractures; » a positive Gower’s sign (though this is not pathognomonic of DMD, as it can be seen in other forms of muscular dystrophy); and » wheelchair dependency by early teens. Progression tends to be more rapid than that of other LGMDs, with loss of ambulation usually at 12–16 years but can be as early as 10 years. A total of 300 individuals with ARLGMD were recruited for this study. The disorder is slowly progressive, with later involvement of the upper limbs and fatty replacement of muscle tissue apparent on MRI. In Duchene muscular dystrophy (DMD), the muscles waste away and are replaced by fat and scar tissue - a process termed as fibrosis. In the early stages of DMD, the weakness of proximal muscles manifests by affected patients ‘climbing up their own bodies with their hands’ (Gower's sign) when rising from the floor to the standing position (Biggar, 2006). Deleterious consequences of muscle hypertrophy should be considered when developing treatments for muscular dystrophy. This can result in trouble standing up. Recently, … However, it's often the smaller muscles that are affected first, such as those in the face, jaw and neck. The disorders differ in which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. MDDGA1. Children with DMD invariably have serum levels >10 times normal. Calf muscle hypertrophy in Pompe's disease is a seldom quoted sign, the exact incidence being unknown. Pseudo hypertrophy of the calf muscle is classic. Open in figure viewer PowerPoint. It affects the same number of men and women. Muscle weakness usually begins around the age of four, and worsens quickly. Test for creatine kinase levels if you suspect any neuromuscular condition. Many people will eventually become unable to walk. Especially calf; May be generalized; Increases with age; Most commonly due to: Muscle replacement by fat & connective tissue ; Some relatively spared muscles may have true hypertrophy Musculoskeletal. You are currently offline. Open in figure viewer PowerPoint. hypertrophy, especially of the calf muscles, is common. He had noticed large calves for as long as hecould remember. Developmental history: examination: gait, run, proximal muscle weakness, calf hypertrophy. Clinical examination revealed: calf hypertrophy, Gowers’s manoeuver, and all had a waddling gait. As with other types of muscular dystrophy, myotonic dystrophy involves progressive muscle weakness and muscle wasting. This renders a false appearance of grossly enlarged muscles, referred to as pseudohypertrophy. Included diseases are the more severe Walker-Warburg syndrome and the slightly less severe muscle-eye-brain disease. Between the ages of 3 and 7, parents may be falsely encouraged by seeming improvement. Muscular dystrophy (MD) is a group of muscle diseases that results in increasing weakening and breakdown of skeletal muscles over time. Causes - Limb-girdle muscular dystrophy- type 2C Muscular dystrophy is caused by various genetic mechanisms. Consider Duchenne muscular dystrophy in boys with delayed motor milestones, positive Gowers’ sign, abnormal gait, muscle pains, calf hypertrophy, unexplained elevated liver enzymes, learning difficulties, behavioural problems, or speech and language delay. Autosomal recessive limb-girdle muscular dystrophy-26 (LGMDR26) is a muscle disorder characterized by adult-onset weakness primarily affecting the proximal muscles of the lower limbs. Hypertrophy of the calf is common, and the tongue muscles may become enlarged. Facioscapulohumeral muscular dystrophy (FSHD; MIM158900) ... Atypical features have been reported, including less facial involvement, neck weakness, calf hypertrophy, and preferential involvement of lower limbs . All patients had calf hypertrophy and normal strength in gastrocnemius-soleus, whereas the quadriceps biopsied were all atrophied and weak. The clinical observations on muscle bulk in DMD suggest infraspinatus and deltoid to be the second and third most common hypertrophied muscles after the calf. The child shows little signs before the age of 3 years [1,2]. Adults usually remain ambulant. - "The Muscular Dystrophies" FIGURE 2-1 Calf hypertrophy in a 4-year-old boy with Duchenne muscular dystrophy. DMD is caused by the absence of dystrophin—a protein which links the sarcomere and the extracellular matrix, by anchoring the sarcolemma to the outermost myofilament layer of myofibres. Casereport A28-year-old Malaysian gave an 8-year history of inability to run, difficulty in climbing stairs and getting out of low chairs. Duchenne muscular dystrophy (DMD), an X-linked disorder, is the most common muscular dystrophy in children, presenting in early childhood and characterized by proximal muscle weakness and calf hypertrophy in affected boys. Becker's dystrophy is an X-linked recessive disorder usually caused by in-frame mutations of the dystrophin gene, resulting in a deficiency of dystrophin or a dys-trophin molecule of abnormal structure. This renders a false appearance of grossly enlarged muscles, referred to as pseudohypertrophy. Muscle hypertrophy. Some affected individuals experience mild to severe breathing problems related to the weakness of muscles needed for breathing. INTRODUCTION: Calf hypertrophy is a common feature in Becker muscular dystrophy (BMD), and it is still debated to which extent fatty degeneration or true muscle hypertrophy [ncbi.nlm.nih.gov] His mother experienced walking difficulties from 35 years of age and has a myopathy with marked calf hypertrophy , a raised CK, and a myopathic muscle biopsy. A 4-year-old boy presents with a history of ambulation delayed until 18 months of age, toe walking, calf hypertrophy, and proximal hip girdle muscle weakness. The presentation of an adolescent female with limb-girdle pattern of weakness and calf hypertrophy had initially led to the consideration of other myopathies including limb-girdle myopathies in the patient. Calf hypertrophy was evident on physical examination in 20 of 26 (77%) BMD cases in another study. Muscular Dystrophy 2G Amirtharaj Francis1, Balaraju Sunitha2, ... calf hypertrophy and loss of ambulation.
