BECKER MUSCULAR DYSTROPHY

INTRODUCTION:-

→ Becker muscular dystrophy is an inherited disorder that involves slowly worsening muscle weakness of the legs and pelvis.

• SYMPTOMES:-

→ Symptoms usually begin in childhood. The average age at diagnosis is 11 years but there is a wide age range. The clinical severity varies.

Early symptoms
→ Delayed walking (sometimes).
→ Muscle cramps on exercise.
→ Most BMD children are not ‘athletic’ and may struggle with school sports.

Later symptoms
→ Muscle weakness
→ Affects the proximal muscles of the limbs mainly.
→ May begin in teenage years or 20s, causing difficulty in climbing stairs, fast walking and lifting heavy objects.
→ BMD patients can walk independently until the age of 16 or later (cf DMD, where patients cannot walk beyond the age of 12). Walking ability is lost (usually at the age of 40-60) but sometimes earlier, around the age of 20-30.

• Signs
→ Wasting of the proximal muscles; hypertrophy of others, particularly the calf muscles.

• Other presentations
→ Myoglobinuria.
→ Anaesthetic complications – a dangerous, malignant hyperthermia-like reaction with some anaesthetic agents.
→ Cardiomyopathy may be the first presentation, if muscle weakness is subclinical.
→ There is a higher incidence of learning difficulties, behavioural problems and autistic spectrum disorders, compared with the general population.

• RISK FACTOR:-
→ The disease almost always affects males, though it can occur in females. You’re at a higher risk if you have relatives with the condition.

• DIAGNOSIS:-
→ doctor will examine you thoroughly, looking for deformed muscles and bones, abnormal heart rhythms, and muscle loss. doctor may order a number of tests, including:

→ Blood tests to measure the levels of enzymes released from damaged muscles
→ Electrical stimulation of nerves to measure your muscle function
→ A muscle tissue sample to check for signs of muscular dystrophy
→ Gene analysis to look for an abnormal dystrophin gene
→ Tests of your heart and lung function
→ X-rays of your spine

• TREATMENT:-
→ There is no known cure for Becker muscular dystrophy yet. Treatment is aimed at control of symptoms to maximize the quality of life which can be measured by specific questionnaires. Activity is encouraged. Inactivity (such as bed rest) or sitting down for too long can worsen the muscle disease. Physical therapy may be helpful to maintain muscle strength. Orthopedic appliances such as braces and wheelchairs may improve mobility and self-care.

→ Immunosuppressant steroids have been known to help slow the progression of Becker muscular dystrophy. The drug prednisone contributes to an increased production of the protein utrophin which closely resembles dystrophin, the protein that is defective in BMD.
→ The cardiac problems that occur with EDMD and myotonic muscular dystrophy may require a pacemaker.
The investigational drug Debio-025 is a known inhibitor of the protein cyclophilin D, which regulates the swelling of mitochondria in response to cellular injury. Researchers decided to test the drug in mice engineered to carry MD after earlier laboratory tests showed deleting a gene that encodes cycolphilin D reduced swelling and reversed or prevented the disease’s muscle-damaging characteristics. According to a review by Bushby. if a primary protein is not functioning properly then maybe another protein could take its place by augmenting it. Up regulation of compensatory proteins has been done in models of transgenic mice.

BRONCHIECTASIS

INTRODUCTION: Bronchiectasis means abnormal dilatation of the bronchi due to chronic airway inflammation and infection. It is usually acquired, but may result from an underlying genetic or congenital defect of airway defences. CAUSES: Congenital • Cystic fibrosis • Primary ciliary dyskinesia • Kartagener’s syndrome (sinusitis and transposition of the viscera) • Primary hypogammaglobulinaemia Acquired • Pneumonia (complicating whooping cough or measles) • Inhaled foreign body • Suppurative pneumonia • Pulmonary TB • Allergic bronchopulmonary aspergillosis complicating asthma • Bronchial tumours CLINICAL FEATURES: ● Chronic cough productive of purulent sputum. ● Pleuritic pain. ● Haemoptysis. ● Halitosis. Acute exacerbations may cause fever and increase these symptoms. Examination reveals coarse crackles caused by sputum in bronchiectatic spaces. Diminished breath sounds may indicate lobar collapse. Bronchial breathing due to scarring may be heard in advanced disease. INVESTIG...

CARDIAC REHABILITATION

Introduction “Cardiac Rehabilitation is the process by which patients with cardiac disease, in partnership with a multidisciplinary team of health professionals are encouraged to support and achieve and maintain optimal physical and psychosocial health. The involvement of partners, other family members and carers is also important”. Cardiac rehabilitation is an accepted form of management for people with cardiac disease. Initially, rehabilitation was offered mainly to people recovering from a myocardial infraction (MI), but now encompasses a wide range of cardiac problems. To achieve the goals of cardiac rehabilitation a multidisciplinary team approach is required. The multidisciplinary team members include: Cardiologist/Physician and co-coordinator to lead cardiac rehabilitation Clinical Nurse Specialist Physiotherapist Clinical nutritionist/Dietitian Occupational Therapist Pharmacist Psychologist Smoking cessation counsellor/nurse Social worker Vocational counsellor Clerical Ad...

CARDIAC ARREST AND RESUSCITATION

INTRODUCTION: The leading causes of sudden death before old age, in people over the age of 44, are ventricular fibrillation from asymptomatic ischaemic heart disease or non-traumatic accidents such as drowning and poisoning. In people under the age of 38, the commonest causes are traumatic, due to accident or violence. In such instances death may be prevented if airway obstruction can be reversed, apnoea or hypoventilation avoided, blood loss prevented or corrected and the person not allowed to be pulseless or hypoxic for more than 2 or 3 minutes. If, however, there is circulatory arrest for more than a few minutes, or if blood loss or severe hypoxia remain uncorrected, irreversible brain damage may result. Immediate resuscitation is capable of preventing death and brain damage. The techniques required may be used anywhere, with or without equipment, and by anyone, from the lay public to medical specialists, provided they have been appropriately trained. Resuscitation may be divided in...

RELAXED POSITIONS FOR BREATHLESS PATIENTS

Relaxation positions for the breathless patient If patients can be taught how to control their breathing during an attack of dyspnoea, this can be of great benefit to them. The patient should be put into a relaxed position, and encouraged to do ‘diaphragmatic’ breathing at his own rate. The rate of breathing does not matter at this stage; it is the pattern of breathing that is important. As the patient gains control of his breathing he should be encouraged to slow down his respiratory rate. Any of the following positions will assist relaxation of the upper chest while encouraging controlled diaphragmatic breathing. They can be adapted to various situations in everyday life. HIGH SIDE LYING Five or six pillows are used to raise the patient’s shoulders while lying on his side. One pillow should be placed between the waist and axilla, to keep the spine straight and prevent slipping down the bed. The top pillow must be above the shoulders, so that only the head and neck are supp...

PARKINSON'S DISEASE

Parkinson's EtiologyParkinson's disease (PD) is a neurodegenerative disorder that mostly presents in later life with generalized slowing of movements (bradykinesia) and at least one other symptom of resting tremor or rigidity. Other associated features are a loss of smell, sleep dysfunction, mood disorders, excess salivation, constipation, and excessive periodic limb movements in sleep (REM behavior disorder). PD is a disorder of the basal ganglia, which is composed of many other nuclei. The striatum receives excitatory and inhibitory input from several parts of the cortex. The key pathology is the loss of dopaminergic neurons that lead to the symptom . It is the seconds most common neuro-degenerative condition in the world after Alzheimer's. The condition is caused by the slow deterioration of the nerve cells in the brain, which create dopamine. Dopamine is a natural substance found in the brain that plays a major role in our brains and bodies by messag...
