The heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a heart rate that is too slow – below 60 beats per minute – is called bradycardia .

Common symptoms - There may be no symptoms. Alternatively, symptoms may include a fluttering in the chest, chest pain, fainting or dizziness.

Treatment - If required, treatment includes anti-arrhythmic drugs, medical procedures, implantable devices and surgery. ]]> 2021-10-21 10:37:14 UTC https://padlet.com/sg131093/n5u0c3l8nuz5topk/wish/1833089111 CONNECTIVE TISSUE sg131161 https://padlet.com/sg131093/n5u0c3l8nuz5topk/wish/1837636827 Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.

The inflammation can be so severe that it affects how the joints and other parts of the body look and function. It may cause deformities or irregularity in the joints of the fingers. This makes moving your hands difficult. Lumps, known as rheumatoid nodules, may form anywhere in the body.

Common symptoms - Tender, warm, swollen joints , joint stiffness that is usually worse in the mornings and after inactivity , fatigue, fever , loss of appetite .

Treatment - While there's no cure for rheumatoid arthritis, physiotherapy and medication can help slow the disease's progression. Most cases can be managed with a class of medications called anti-rheumatic drugs .

It can affect the joints, skin, cartilage, and internal organs. It is degenerative and gets worse over time. The disease can be in one part of the body. This is called localized scleroderma. Or it may affect the whole body. This is a more serious condition called systemic sclerosis. Scleroderma is more common in women.

Common symptoms - Symptoms include tightening of the skin, joint pain, exaggerated response to cold (Raynaud's disease) and heartburn.

Treatment - Treatments include medication, physiotherapy and surgery.]]> 2021-10-23 05:52:02 UTC https://padlet.com/sg131093/n5u0c3l8nuz5topk/wish/1837643349 DISORDERS OF CONNECTIVE TISSUES sg131161 https://padlet.com/sg131093/n5u0c3l8nuz5topk/wish/1837644446 Connective tissues hold the structures of the body together. They are made up of two different proteins, collagen and elastin. Collagen is found in the tendons, ligaments, skin, cartilage, bone and blood vessels. Elastin is found in the ligaments and skin. When these connective tissues become inflamed, this can harm the proteins and surrounding areas of the body.

Nerve cell damage in the brain causes dopamine levels to drop, leading to the symptoms of Parkinson's.

The cause is usually a change in the normal balance of vaginal bacteria or an infection. Reduced estrogen levels after menopause and some skin disorders can also cause vaginitis. Vaginitis is usually caused by a change in the normal balance of vaginal bacteria, an infection or reduced oestrogen levels after menopause.

Common symptoms - unusual vaginal discharge, itching or irritation, painful urination and pain during intercourse.

Treatment - Treatment usually involves medication that focuses on the underlying cause.

Sometimes an individual will show only some features associated with the condition. In this case, they are described as "Marfanoid" or "Marfan-like." Once Marfan syndrome has been identified in a family, it is important that all members to evaluated for it. It is particularly important to have regular diagnostic testing of the aorta and heart for early detection of abnormalities, which may become life-threatening.  Anyone who may have Marfan or Marfanoid syndrome should be screened with echocardiography every year. Once the aorta, as it rises above the heart, is larger than 3.5 centimeters, screening with echocardiography should be done every six months.

Common symptoms - There is a great variation in symptoms between one individual with Marfan syndrome and another.  People with Marfan syndrome are tall and thin with long arms, legs, fingers and toes.

Treatment - Treatment includes medication to keep blood pressure low, glasses or contact lenses and surgery.

When the kidney is injured, it cannot get rid of wastes and extra fluid in the body. If the illness continues, the kidneys may stop working completely, resulting in kidney failure.

Common symptoms - Pink or cola-colored urine from red blood cells in your urine (hematuria) , foamy urine due to excess protein (proteinuria) , hypertension and fluid retention (edema) with swelling evident in your face, hands, feet and abdomen.

Treatment - Intake of angiotensin-converting enzyme inhibitors (ACE) inhibitors to control high blood pressure or angiotensin receptor blockers (ARBs)  , undergoing plasmapheresis . If the condition becomes advanced such that it leads to kidney failure , dialysis is carried out . Gradually , a kidney transplant might be required .

Neurofibromatosis is usually non-cancerous. There are three types of this condition.
 Type 1 usually appears in childhood, while Types 2 and 3 appear in early adulthood.
Type 1 can cause bone deformities, learning disabilities and high blood pressure. 
Type 2 can cause hearing loss, vision loss and difficulty with balance.
 Type 3 can cause chronic pain throughout the body.

Common symptoms – Lisch nodules , lumps on skin , lumps under skin , café au lait spots and skin fold freckling .

Treatment - Some cases may not require treatment other than careful observation. Other cases may require chemotherapy, radiation therapy or surgery .

Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills.

Common symptoms - Memory loss is the key symptom of Alzheimer's disease. Early signs include difficulty remembering recent events or conversations. As the disease progresses, memory impairments worsen and other symptoms develop.

Treatment - An important part of diagnosing Alzheimer's disease includes being able to explain your symptoms, as well as perspective from a close family member or friend about symptoms and their impact on daily life. Additionally, a diagnosis of Alzheimer's disease is based on tests your doctor administers to assess memory and thinking skills. Laboratory and imaging tests can rule out other potential causes or help the doctor better identify the disease causing dementia symptoms.

The inflammation can reduce your heart's ability to pump and cause rapid or abnormal heart rhythms (arrhythmias). Infection with a virus usually causes myocarditis. Sometimes myocarditis can result from a reaction to a drug or be part of a more general inflammatory condition. Signs and symptoms include chest pain, fatigue, shortness of breath, and rapid or irregular heartbeats. Severe myocarditis weakens your heart so that the rest of your body doesn't get enough blood. Clots can form in your heart, leading to a stroke or heart attack.

Common symptoms - Symptoms include chest pain, abnormal heartbeat and shortness of breath.

Treatment - The treatment for myocarditis depends on the cause.

If it is not treated, esophagitis can become very uncomfortable, causing difficulty in swallowing, and ulcers or scarring of the esophagus. Causes include stomach acids backing up into the tube, infection, some medication and allergies. Oesophagitis often causes painful, difficult swallowing and chest pain with eating.

Common symptoms - Emergency symptoms include food stuck in the oesophagus and chest pain that lasts more than a few minutes.
