Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen. The MCA is the most common site for the occurrence of ischemic stroke.[1] Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with MCA syndrome. More distal blockages tend to produce milder deficits due to more extensive branching of the artery and less ischemic response. In contrast, the most proximal occlusions result in widespread effects that can lead to significant cerebral edema, increased intracranial pressure, loss of consciousness and could even be fatal.[1] In such occasions, mannitol (osmotic diuretic) or hypertonic saline are given to draw fluid out of the oedematus cerebrum to minimise secondary injury. Hypertonic saline is better than mannitol, as mannitol being a diuretic will decrease the mean arterial pressure and since cerebral perfusion is mean arterial pressure minus intracranial pressure, mannitol will also cause a decrease in cerebral perfusion. Contralateral hemiparesis and hemisensory loss of the face, upper and lower extremities is the most common presentation of MCA syndrome.[1] Lower extremity function is more spared than that of the faciobrachial region.[2] The majority of the primary motor and somatosensory cortices are supplied by the MCA and the cortical homunculus can, therefore, be used to localize the defects more precisely.it is important to note that middle cerebral artery lesions mostly affect the dominant hemisphere i.e. the left cerebral hemisphere.

Myocardial infarction (MI), commonly known as a heart attack, is defined pathologically as the irreversible death of myocardial cells caused by ischemia. Clinically, MI is a syndrome that can be recognized by a set of symptoms, chest pain being the hallmark of these symptoms in most cases, supported by biochemical laboratory changes, electrocardiographic (ECG) changes, or findings on imaging modalities able to detect myocardial injury and necrosis. According to the third universal definition of MI, implemented by a joint task force from the European Society of Cardiology (ESC), American College of Cardiology (ACC) Foundation, American Heart Association (AHA), and the World Heart Federation (WHF), MI is diagnosed when either of the following two criteria are met

The term chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) has been used to identify patients with a chronically progressive or relapsing symmetric sensorimotor disorder with cytoalbuminologic dissociation and interstitial and perivascular endoneurial infiltration by lymphocytes and macrophages. It can be considered the chronic equivalent of acute inflammatory demyelinating polyradiculoneuropathy, the most common form of Guillain-Barré syndrome. Signs and symptoms CIDP typically starts insidiously and evolves slowly, in either a slowly progressive or a relapsing manner, with partial or complete recovery between recurrences; periods of worsening and improvement usually last weeks or months. Most experts consider the necessary duration of symptoms to be greater than 8 weeks for the diagnosis of CIDP to be made. Symptoms reported include the following: Preceding infection (infrequent) Initial limb weakness, both proximal and distal Sensory symptoms (eg, tingling and numbness of hands and feet) Motor symptoms (usually predominant) In about 16% of patients, a relatively acute or subacute onset of symptoms In children, usually a more precipitous onset of symptoms Symptoms of autonomic system dysfunction (eg, orthostatic dizziness) Pertinent physical findings are limited to the nervous system, except when the condition is associated with other diseases. Such findings may include the following. Signs of cranial nerve (CN) involvement (eg, facial muscle paralysis or diplopia) Gait abnormalities Motor deficits (eg, symmetric weakness of both proximal and distal muscles in upper and lower extremities) Diminished or absent deep tendon reflexes Sensory deficits (typically in stocking-glove distribution) Impaired coordination See Clinical Presentation for more detail. Diagnosis Laboratory studies that may be helpful include the following: Cerebrospinal fluid analysis: Elevated protein levels are common (80% of patients); 10% of patients also have mild lymphocytic pleocytosis and increased gamma globulin Complete blood count (CBC), erythrocyte sedimentation rate (ESR), antinuclear antibody (ANA) level, biochemistry profile, and serum and urine immunoelectrophoresis (to exclude associated systemic disorders) In certain instances, genetic testing Other tests and procedures that may be warranted are as follows: MRI of the spine with gadolinium enhancement Electromyography (EMG) is a critical test to determine whether the disorder is truly a peripheral neuropathy and whether the neuropathy is demyelinating Peripheral (sural) nerve biopsy (see the image below): This is considered when the diagnosis is not completely clear, when other causes cannot be excluded, or when profound axonal involvement is observed on EMG; biopsy was once commonly recommended for most patients before immunosuppressive therapy, but current guidelines no longer recommend it

Heat stroke is the most serious form of heat injury and is considered a medical emergency. If you suspect that someone has heat stroke -- also known as sunstroke -- call 911 immediately and give first aid until paramedics arrive. Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes. Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps, heat syncope (fainting), and heat exhaustion. But it can strike even if you have no previous signs of heat injury. Heat stroke results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system. The medical definition of heat stroke is a core body temperature greater than 105 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness or coma

Dehydration is a condition that occurs when the loss of body fluids, mostly water, exceeds the amount that is taken in. With dehydration, more water is moving out of our cells and bodies than what we take in through drinking. We lose water every day in the form of water vapor in the breath we exhale and in our excreted sweat, urine, and stool. Along with the water, small amounts of salts are also lost.

Surgery is done to relieve pressure on the nerve roots. This can help reduce pain, numbness, and weakness in your legs. Surgery may be recommended if: Your pain, numbness, or weakness is so bad that it gets in the way of normal daily activities and hurts your quality of life. You are in otherwise good health. The goal of surgery is to relieve pain, numbness, or weakness in the legs-not to relieve back pain. People who have surgery only for back pain are less satisfied with the results than are those who have surgery for nerve root symptoms and pain in both the back and legs. Also, numbness, weakness, and pain may return after surgery.

Before deciding how to treat one episode of high blood glucose, it is important to figure out why the number is high. Some possible causes include eating a heavy meal, not getting enough physical activity, forgetting to take diabetes medication, and dealing with illness and stress. Insulin is the medication that will bring blood glucose down the fastest. Someone who uses mealtime insulin can take correction doses to lower blood glucose. This requires a thorough understanding of when to inject, how often to give correction doses, and how much insulin to use. You will need to work with your doctor or diabetes educator to learn how to do this. Apart from administering insulin, the fastest way to lower your blood glucose is to engage in physical activity. Exercise results in an increased sensitivity to insulin. It causes your muscle cells to take up more glucose, leaving less of it to circulate in your bloodstream during and after the physical activity (which means a lower blood glucose when you test). Frequent, regular exercise is very important to good blood glucose control no matter what type of diabetes you have. Research has shown that it is vital in warding off long-term complications like neuropathy, retinopathy, and heart and kidney diseases. Don't forget to check with a doctor, though, before making any major changes to your exercise routine. And, if you have type 1 diabetes and your glucose is 250 mg/dl or higher, check for urine ketones. You should not exercise if ketones are present.

Idiopathic thrombocytopenic purpura (ITP) is a disorder that can lead to easy or excessive bruising and bleeding. The bleeding results from unusually low levels of platelets — the cells that help blood clot. Idiopathic thrombocytopenic purpura, which is also called immune thrombocytopenia, affects children and adults. Children often develop ITP after a viral infection and usually recover fully without treatment. In adults, the disorder is often long term. If you don't have signs of bleeding and your platelet count isn't too low, you may not need any treatment. In rare cases, the number of platelets may be so low that dangerous internal bleeding occurs. Treatment options are available.

Depending on the underlying cause, some types of kidney disease can be treated. Often, though, chronic kidney disease has no cure. Treatment usually consists of measures to help control signs and symptoms, reduce complications, and slow progression of the disease. If your kidneys become severely damaged, you may need treatment for end-stage kidney disease. Treating the cause Your doctor will work to slow or control the cause of your kidney disease. Treatment options vary, depending on the cause. But kidney damage can continue to worsen even when an underlying condition, such as high blood pressure, has been controlled. Treating complications Kidney disease complications can be controlled to make you more comfortable. Treatments may include: High blood pressure medications. People with kidney disease may experience worsening high blood pressure. Your doctor may recommend medications to lower your blood pressure — commonly angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers — and to preserve kidney function. High blood pressure medications can initially decrease kidney function and change electrolyte levels, so you may need frequent blood tests to monitor your condition. Your doctor will likely also recommend a water pill (diuretic) and a low-salt diet. Medications to lower cholesterol levels. Your doctor may recommend medications called statins to lower your cholesterol. People with chronic kidney disease often experience high levels of bad cholesterol, which can increase the risk of heart disease. Medications to treat anemia. In certain situations, your doctor may recommend supplements of the hormone erythropoietin (uh-rith-roe-POI-uh-tin), sometimes with added iron. Erythropoietin supplements aid in production of more red blood cells, which may relieve fatigue and weakness associated with anemia. Medications to relieve swelling. People with chronic kidney disease may retain fluids. This can lead to swelling in the legs, as well as high blood pressure. Medications called diuretics can help maintain the balance of fluids in your body. Medications to protect your bones. Your doctor may prescribe calcium and vitamin D supplements to prevent weak bones and lower your risk of fracture. You may also take medication known as a phosphate binder to lower the amount of phosphate in your blood, and protect your blood vessels from damage by calcium deposits (calcification). A lower protein diet to minimize waste products in your blood. As your body processes protein from foods, it creates waste products that your kidneys must filter from your blood. To reduce the amount of work your kidneys must do, your doctor may recommend eating less protein. Your doctor may also ask you to meet with a dietitian who can suggest ways to lower your protein intake while still eating a healthy diet.

Your doctor says your chest pain (angina) is caused by blockages in your heart arteries and that you need to get those blockages taken care of. What are your options? First, it's important to determine what type of angina you have. Different types of angina may need different treatments. Common types of angina are chronic stable angina — a type of angina that occurs when your heart is working hard — and unstable angina, which is new chest pain or chest pain that is getting worse. Other types of angina include variant angina — a rare type of angina caused by a spasm in the coronary arteries — and microvascular angina, which can be a symptom of disease in the small coronary artery blood vessels. Unstable angina is a serious situation and requires emergency treatment. Treatment for unstable angina involves hospitalization with medications to stabilize your condition. Some people with unstable angina may require a procedure called angioplasty (also known as percutaneous coronary intervention), usually combined with the placement of a small metal tube called a stent. In some cases of unstable angina, heart surgery (coronary bypass surgery) may be needed. Generally, if you have mild stable angina that is controlled by medications, you may not need further treatments. If you're experiencing symptoms of chronic stable angina even after taking medications and making lifestyle changes, or if you're at higher risk of serious heart disease, your doctor may recommend angioplasty or coronary bypass surgery. Making a decision on how to treat your angina can be difficult, but knowing the benefits and risks of stents and medications may help you decide.
