...Muscular Dystrophy Disease diary #2 Today I will be explaining Muscular Dystrophy and all of the types. So let’s start off with what it is. Muscular Dystrophy is an inherited disease that causes muscles to progressively become weaker. In some forms it causes the heart and organs to weaken. Some forms only appear in men but many are in both men and women. There are eight major types of Muscular Dystrophy that I will be explaining next. So let’s move on to see what kind of Dystrophy there is. The first type is called Myotonic. This form appears most common in adults but can appear mainly from childhood to adults. This can appear in newborns but it is very rare. The next type is Duchenne. This is one of the types that only appear in men. It affects 1 in 3500 people. Most people affected in this form usually die before age 20....

...Introduction Duchenne muscular dystrophy, named after the neurologist who first described it, Guillaume Benjamin Amand Duchenne in the 1800, is a common type of muscular dystrophy among children, in which the muscle becomes weak and degenerates progressively. Prior to 1986, there was very little information before MDA-supported researchers succeeded in the identification of the particular gene on the X-chromosome that after mutation led to the disease (MDA, 2016). The gene was identified and named as dystrophin. Dystrophin is a protein that aids in keeping the muscles together. Duchenne muscular dystrophy is heritable as an X-linked recessive gene and is passed by the mother who is often referred to as a carrier. The disease majorly affects...

...cells are dying and bursting. The contents of the cells are being released into the bloodstream leading to the symptoms of Rhabdomyolysis. There are many different causes leading to Rhabdomyolysis and they can be classified into two categories known as environmental causes and internal causes. Two environmental causes are: The use of alcohol or illegal drugs such as heroin, cocaine or amphetamines and a crush injury such as from an auto accident, fall, or building collapse. Two internal causes are: Extreme muscle strain, especially in someone who is an untrained athlete and also blocked blood vessels can cause this along with diseases of the muscles (myopathy) such as congenital muscle enzyme deficiency or Duchenne's muscular dystrophy. Rhabdomyolysis is treatable and patients may recover quickly if the disease is caught in its early stages. Treatment with intravenous (IV) fluids helps maintain urine production and prevent kidney failure. Rarely, dialysis treatment may be needed to help your kidneys filter waste products while they are recovering. Management of electrolyte abnormalities (potassium, calcium and phosphorus) helps protect your heart and other organs. You may also need a surgical procedure (fasciotomy) to relieve tension or pressure and loss of circulation if compartment syndrome threatens muscle death or nerve damage. In some cases, you may...

...With Duchenne muscular dystrophy, individuals experience a decline in dexterity and gross motor skills as the condition progresses. As muscles atrophy, compensation for lack of strength and dexterity may include modified handles or grips and adapted utensils and the use of a motorized wheelchair. (Heller, Forney, Alberto, Best, & Schwartzman, 2009.) The individual and instructor will work with the special education team and therapists for compensatory positioning that allows access to various classroom materials and accessibility within the classroom. Compensatory positioning may include assisting the student with positioning within the wheelchair, classroom arrangement that allows wheelchair access, the use of wheelchair accessible desks, and the position of the wheelchair accessible desk within the classroom as the student may need to have a unobstructed view of the board at all times due to an inability to reposition his or her own body. (Heller, et. al., 2009.) Adapted physical education and range of motion exercises can assist the student with preventing contractures, when the muscles deteriorates joints may become fixed, which limits mobility. (Muscular Dystrophy Association, n.d.) The student should only exercise as recommended by a physician and not exercise to the point of exhaustion because this may harm muscle tissues. (Muscular Dystrophy Association, n.d.) The student may also attend physical and occupational therapy regularly to assist with keeping the body ambulatory...

...Muscular I. Introduction of the disease A. Muscular dystrophy B. Muscular dystrophy-is a group of muscle diseases that weaken the musculoskeletal and hamper C. I pick this disease because it sounded interesting II. Causes A. How can a human being contract (get) this disease? 1. the most common form of muscular dystrophy in children is Duchene muscular dystrophy (DMD). Becker muscular dystrophy (BMD) is also relatively common. They are similar and are caused by mutations in the same gene, but BMD is less severe than DMD. 2. You can be born with this disorder 3. And it’s a genetic disorder B. Is this disease contagious? no III. Symptoms A. Poor balancing B. Frequent falls C. Limited range movements D. Inability to walk IV. Treatment A. Corticosteroids, such as prednisone, may help improve muscle strength and delay the progression of certain types of muscular dystrophy. But prolonged use of these types of drugs can weaken bones and increase fracture risk. B. Several different types of therapy and assistive devices can improve quality and sometimes length of life in people who have muscular dystrophy. C. Surgical remedies are an option for several of the problems common to muscular dystrophy, such as: Contractures. Tendon surgery can loosen joints drawn inward by contractures. Scoliosis. Surgery may also be needed to correct a sideways curvature of the spine that can make breathing more difficult. C. V. Cures-doesn’t have any cures-doesn’t...

...a disability, it’s a condition making the argument against the city that she is a handicap invalid. Technically she’s not a handicap- If you can no longer work due to scoliosis, you may be eligible to receive Social Security Disability benefits which she did not apply for at the time. Scoliosis is a lateral (toward the side) curvature in the normally straight vertical line of the spine. When viewed from the side, the spine should show a mild roundness in the upper back and shows a degree of swayback (inward curvature) in the lower back. Types of Scoliosis – conditions 1. Neuromuscular scoliosis. A result of abnormal muscles or nerves. Frequently seen in people with other disorders, including other birth defects such as muscular dystrophy, cerebral palsy, Spina bifida or Marfan syndrome (an inherited connective tissue disease) those with various conditions that are accompanied by it, result in, paralysis. : In this type of scoliosis, there is a problem when the bones of the spine are formed. Either the bones of the spine fail to form completely or they fail to separate from each other during fetal development. People with these conditions often develop a long C-shaped curve and have weak muscles that are unable to hold them up straight. If the curve is present at birth, it is called congenital. (Congenital scoliosis caused by a bone abnormality present at birth .This type of scoliosis is often much more severe and needs more aggressive treatment than other forms of scoliosis...

...Proposal: “The effects of taking a break during physical therapy for patients with Duchenne muscular dystrophy” HSC 4730 Background: Duchenne Muscular Dystrophy (DMD) or medically known as pseudohypertrophic muscular dystrophy is a genetic, degenerative disorder found predominantly in males. It is a recessive X-linked chromosome that affects approximately 1 in 3,500 male’s worldwide.3 The boys found with Duchenne’s have an absence of the protein, dystrophin, leaving them with continuing loss of muscular function.7 Regardless of current efforts, by the age of twelve, most who suffer from DMD depend upon a wheelchair for mobility.13 The purpose of the study is to delay the progression of DMD in boys between five to ten years of age. The intervention for the study is to apply a period of rest in their physical therapy to allow for their central nervous system to process the information. The central nervous system can take between seven to fourteen days to process information in order for the body to recover.2 With the recovery time given to these patients, we can determine a successful intervention or one that further deteriorates muscle mass. The time breaks allow the central nervous system (CNS) a set period of recovery in order to determine a change in the muscular degeneration rate. Corticosteroids are a steroid hormone produced in the adrenal cortex. It can also be synthetically made and regularly prescribed to patients with DMD. Corticoid steroids, along with physical...

...Domain and Kingdom: Eukaryota, Animalia My favorite sequence is: Dystrophin gene This sequence codes for: Dystrophin gene codes for an important muscle protein called dystrophin that helps maintain and hold together the structure of muscle cells. Localization: The DMD gene is located on the short (p) arm of the X chromosome at position 21.2. In a membrane-spanning protein complex it is located at the muscle sarcolemma that connects the cytoskeleton to the basal lamina. Gene expression: In the Dystrophin gene, there are 7 tissue-specific promoters. The promoters responsible for transcription are dp427m, dp427c, dp427p, dp260, dp140, dp116, and dp71 respectively. Its expression in muscle cells is brought by dystrophin promoter bending factor (DPBF) and the binding of positive regulators serum response factor on a regulatory CArG element present on the promoter. RNA processing: Numerous phosphorylation sites were identified in dystrophin that are believed to regulate its interactions with dystrophin-glycoprotein complexes, cytoskeletal, and signaling proteins. Listed are the protein kinases and their effected changes. cAMP-dependent protein kinase (PKA) Indirectly produces a conformational change in the N-ABD, enriching its affinity for myofibrillar actin Protein kinase C (PKC) An inhibitory effect on the dystrophin-actin interaction Casein kinase II (CKII) An inhibitory effect on the dystrophin-actin interaction Glycogen-synthase kinase (GSK3) Inhibitor of ERMS growth inhibiting...

...Duchenne Muscular Dystrophy Muscular Dystrophy is a genetic disorder that causes one muscle weakness. This genetic disorder prevents the body from a protein that is integral for the body to build muscles and to build strength in the muscles, as well. There are several different types of muscular dystrophy and the symptoms of each may vary. The most commonly known muscular dystrophy is known as Duchenne Muscular Dystrophy. This genetic disorder prevents one from all types of muscle movement at such a young age in life. Duchenne Muscular Dystrophy is a genetic disorder that progressively degenerates the muscles and causes weakness. This genetic disorder is caused by the missing protein, dystrophin, which aids in keeping the muscles intact. Without...

...Muscular Dystrophy, or MD, is a mutation that obstructs the production of proteins that is necessary to create healthy muscles. This generates weakness in the body and limits it from functioning properly. The disease can become so terrible that a person with it can no longer do simple tasks with their arms, legs, and extremities such as hands and feet. The cause of MD is due to the lack of dystrophin, a protein found on the X chromosome, which keeps the muscles together. Symptoms of this disorder usually manifest themselves as early as the age of two and three years of age. These signs typically are muscle weakness, the difficulty or inability to stand properly, trouble learning or behavioral problems, not being able to sit or walk without assistance, waddling gait, walking on only the front (toes and balls) of the feet, clumsiness, trouble climbing stairs, not being able to rise from a downward position such as sitting or lying, calves that are larger than usual and sometimes painful, scoliosis (curved spine), and difficulty breathing....

...Adrenoleukodystrophy (ALD) is a male specific disease also known as an X linked disease, woman only carry the disease ALD. A child may seem healthy the first couple years of life. ALD doesn’t start to show until about age five, usual when the child starts kindergarten their behavior with focusing and understanding starts to drastically change. Parents start to pay closer attention to the drastic and rapid change within their child’s behavior. Usual changes within appearance and behavior are loss or motor skills, trouble with language comprehension, loss of hearing, crossed eyes, coma, paralysis, and vision impairment. These symptoms progress rapidly if not found soon enough. What causes these symptoms are caused by a mutated X chromosome. The reason why ALD affects only men is because men only have one X chromosome and the disease mutates the X chromosome resulting in Adrenoluekodystrophy.Also our bodies have a protein called ALPD which helps break down fatty acids. Children who have ALD are unable to breakdown thelong chain of fatty acids, which will go into the brain and spinal cord, adrenal glands and testes. Children will go into a vegetate state within about two years if the disease is not caught in time to slow down the process. The prognosis is patients will mostly likely pass away within one to ten years from the first symptom. Many complications occur with ALD. Typically children will go into a coma for up to about ten years. There are three other types of ALD, adrenomyelopathy...

...Caplan Pathology 3 November 2014 Duchenne Muscular Dystrophy Duchenne muscular dystrophy (DMD) is a common disorder affecting the muscular system. This form of muscular dystrophy is inherited and is caused by a genetic mutation that affects the dystrophin proteins of the muscles. Dystrophin is the largest gene known to man. (Tennyson, Klamut, Warton 1995). Hundreds of genes are responsible for producing the proteins that protect these muscle fibers from damage. In DMD, the dystrophin gene is defective. Where most forms of muscular dystrophy worsen slowly over time, Duchenne grows worse quite rapidly. Duchenne muscular is linked to the X-chromosome so the mother carries the disease and the defective gene but will likely never show symptoms. Their sons will each have a 50% chance of getting the disease and their daughters will each have a 50% chance of being carriers of the disease (Bushby, Finkel, Birnkrant, Case, Clemens, Cripe, Kaul, Kinnett, McDonald, Pandya, Poysky, Shapiro, Tomezsko, Constantin, 2010). The women who are carriers will pass the gene onto their children. One in every 3,500 live male births are diagnosed with Duchenne muscular dystrophy (Chen, Ma, Zhang, Chen, Xing, Wang, Zhang, Luo, 2014). Most of these diagnoses have a line of family history with Duchenne muscular dystrophy that they were unaware of because it had not shown up in several generations. Females who are diagnosed with Duchenne muscular dystrophy and show symptoms tend to have very mild cases compared...

...Duchenne Muscular Dystrophy Duchene Muscular Dystrophy is a genetic disorder that is distinguished by progressive muscle degeneration and weakness. This genetic disorder is cause by an absence of Dystrophin . The onset of symptoms begin early in childhood between the age of three and five. This disease primarily affects males, but in some rare cases it has also affected females. What are the symptoms? As early as three the signs of muscle weakness begin to appear. The first muscles to be affected are the hips, pelvic area, thighs, and shoulders. Later on the voluntary skeletal muscles in the arms, legs, and trunk areas are affected. The calves of those affected are usually enlarged. The heart and respiratory system are affected beginning...
