Digoxin Toxicity
Digoxin Toxicity samer kareem 1,903 Views • 3 years ago

The incidence of digitalis toxicity has declined in recent years, due to decreased use of this drug along with improved technology for monitoring of drug levels and increased awareness of drug interactions. Nevertheless, cardiac glycoside toxicity continues to be a problem in the United States because of the wide use of digoxin (a preparation of digitalis) and its narrow therapeutic window. Digitalis is a plant-derived cardiac glycoside commonly used in the treatment of chronic heart failure (CHF), atrial fibrillation, and reentrant supraventricular tachycardia.[1, 2] Digoxin is the only available preparation of digitalis in the United States. (See Etiology and Epidemiology.) Cardiac glycosides are found in certain flowering plants, such as oleander and lily-of-the-valley. Indigenous people in various parts of the world have used many plant extracts containing cardiac glycosides as arrow and ordeal poisons. The ancient Egyptians used squill (Urginea maritime) as a medicine. The Romans employed it as a diuretic, heart tonic, emetic, and rat poison. Digitalis, or foxglove, was mentioned in the year 1250 in the writings of Welsh physicians. Fuchsius described it botanically 300 years later and named it Digitalis purpurea. William Withering published his classic account of foxglove and some of its medical uses in 1785, remarking upon his experience with digitalis. He recognized many of the signs of digitalis toxicity, noting, "The foxglove, when given in very large and quickly repeated doses, occasions sickness, vomiting, purging, giddiness, confused vision, objects appearing green or yellow; increased secretion of urine, slow pulses, even as low as 35 in a minute, cold sweats, convulsions, syncope, death." (See Presentation and Workup.) During the early 20th century, as a result of the work of Cushny, Mackenzie, Lewis, and others, the drug was gradually recognized as specific for treatment of atrial fibrillation. Only subsequently was the value of digitalis for treatment of CHF established. Cardiac glycosides enhance cardiac contractility and slow conduction through the atrioventricular (AV) junction by increasing vagal tone.[3] (See Etiology.) Cardiac glycoside toxicity has been known to result from ingestion of some plants, including yellow oleander (Thevetia peruviana) and foxglove, and a similar toxidrome has been associated with the use of herbal dietary supplements that contain cardiac glycosides. Digoxin is among the top 50 prescribed drugs in the United States.[4] In 2011, the American Association of Poison Control Centers reported 1601 single exposures to cardiac glycoside drugs.[5] Cardiac glycosides account for 2.6% of toxic plant exposures in the United States.[6, 7] Most of these exposures are in children.[7] (See Epidemiology.) Digoxin-specific fragment antigen-binding (Fab) antibody fragments have contributed significantly to the improved morbidity and mortality of toxic patients since their approval in 1986 by the US Food and Drug Administration (FDA).

Hematuria
Hematuria samer kareem 3,511 Views • 3 years ago

Seeing blood in your urine can cause anxiety. While in many instances there are benign causes, blood in urine (hematuria) can also indicate a serious disorder. Blood that you can see is called gross hematuria. Urinary blood that's visible only under a microscope is known as microscopic hematuria and is found when your doctor tests your urine. Either way, it's important to determine the reason for the bleeding. Treatment depends on the underlying cause.

Type 2 Diabetes
Type 2 Diabetes samer kareem 2,681 Views • 3 years ago

Diabetes, often referred to by doctors as diabetes mellitus, describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body's cells do not respond properly to insulin, or both. Patients with high blood sugar will typically experience polyuria (frequent urination), they will become increasingly thirsty (polydipsia) and hungry (polyphagia).

Cardiac disease in pregnancy
Cardiac disease in pregnancy samer kareem 1,666 Views • 3 years ago

An increased prevalence of cardiovascular disease (CVD) has been found in women of childbearing age,[1] with the presence of CVD in pregnant women posing a difficult clinical scenario in which the responsibility of the treating physician extends to the unborn fetus. Profound changes occur in the maternal circulation that have the potential to adversely affect maternal and fetal health, especially in the presence of underlying heart conditions. Up to 4% of pregnancies may have cardiovascular complications despite no known prior disease. The European Society of Cardiology has published guidelines on the management of cardiovascular disease during pregnancy.[

Infertility
Infertility samer kareem 1,751 Views • 3 years ago

If you and your partner are struggling to have a baby, you're not alone. Ten to 15 percent of couples in the United States are infertile. Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Infertility may result from an issue with either you or your partner, or a combination of factors that interfere with pregnancy. Fortunately, there are many safe and effective therapies that significantly improve your chances of getting pregnant

Pregnancy Symptoms & Signs
Pregnancy Symptoms & Signs samer kareem 2,414 Views • 3 years ago

Every woman is different. So are her experiences of pregnancy. Not every woman has the same symptoms or even the same symptoms from one pregnancy to the next. Also, because the early symptoms of pregnancy often mimic the symptoms you might experience right before and during menstruation, you may not realize you're pregnant. What follows is a description of some of the most common early symptoms of pregnancy. You should know that these symptoms may be caused by other things besides being pregnant. So the fact that you notice some of these symptoms does not necessarily mean you are pregnant. The only way to tell for sure is with a pregnancy test.

A hemangioma (he-man-jee-O-muh) is a birthmark that most commonly appears as a rubbery, bright red nodule of extra blood vessels in the skin. A hemangioma grows during the first year of life, and then recedes over time. A child who had a hemangioma during infancy usually has little visible trace of the growth by age 10.

Interventional Stroke
Interventional Stroke samer kareem 5,373 Views • 3 years ago

The management of acute ischemic stroke has advanced greatly over the past 2 decades. New interventions, including intravenous and endovascular treatment strategies, have evolved to recanalize arteries and salvage the ischemic brain. The evolution of interventional approaches to the treatment of acute stroke has been prompted by the limitations of intravenous therapy and intended to extend the treatment window, improve recanalization rates, and subsequently long-term clinical outcomes. The major techniques that have defined the current field of interventional acute stroke management and the relevant past and current data, and ongoing clinical trials on interventional stroke therapy will be reviewed. New issues, such as futile recanalization, and time to microcatheter, will also be discussed.

Hepatitis A vaccine
Hepatitis A vaccine samer kareem 5,393 Views • 3 years ago

The best way to prevent hepatitis A is through vaccination with the hepatitis A vaccine. Vaccination is recommended for all children age 12 months or older, for travelers to certain countries, and for people at high risk for infection with the virus. The hepatitis A vaccine is given as two shots, six months apart.

Cortisol Resistance & Insulin Resistance
Cortisol Resistance & Insulin Resistance samer kareem 6,858 Views • 3 years ago

Insulin resistance — also called syndrome X or metabolic syndrome— is so pervasive today that we evaluate nearly every woman who visits our clinic to determine her level of risk. Most are taken aback when they learn they either already have insulin resistance syndrome (or as I call it pre-pre diabetic) or are well on their way to developing it. Experts estimate that 25% of all Americans suffer from insulin resistance. We believe the percentage is much higher among perimenopausal women. Because insulin is one of the “major” hormones, it’s also impossible for your body to balance its “minor” hormones (estrogen, progesterone and testosterone among them) until your insulin metabolism is balanced first. To put it simply, if you have hot flashes and you are insulin resistant, it’s going to be nearly impossible to cure the hot flashes without first healing the insulin resistance. Cortisol is also a “major” hormone – to understand it’s role in hormonal balance, read our related articles on adrenal fatigue. The good news is that you can heal insulin resistance. This has been a primary focus of our practice at Women to Women for over a decade, and our approach has been quite successful. Throughout the website you will find simple solutions on how to begin to heal this problematic syndrome.

Disc Herniation
Disc Herniation samer kareem 12,625 Views • 3 years ago

The vertebrae are the bony building blocks of the spine. Between each of the largest parts (bodies) of the vertebrae are the discs. Ligaments are situated around the spine and discs. The spine has seven vertebrae in the neck (cervical vertebrae), 12 vertebrae in the mid-back (thoracic vertebrae), and five vertebrae in the low back (lumbar vertebrae). In addition, in the mid-buttock, beneath the fifth lumbar vertebra, is the sacrum, followed by the tailbone (coccyx).

Autoimmune Disease
Autoimmune Disease samer kareem 4,669 Views • 3 years ago

Your body's immune system protects you from disease and infection. But if you have an autoimmune disease, your immune system attacks healthy cells in your body by mistake. Autoimmune diseases can affect many parts of the body. No one is sure what causes autoimmune diseases. They do tend to run in families. Women - particularly African-American, Hispanic-American, and Native-American women - have a higher risk for some autoimmune diseases. There are more than 80 types of autoimmune diseases, and some have similar symptoms. This makes it hard for your health care provider to know if you really have one of these diseases, and if so, which one. Getting a diagnosis can be frustrating and stressful. Often, the first symptoms are fatigue, muscle aches and a low fever. The classic sign of an autoimmune disease is inflammation, which can cause redness, heat, pain and swelling. The diseases may also have flare-ups, when they get worse, and remissions, when symptoms get better or disappear. Treatment depends on the disease, but in most cases one important goal is to reduce inflammation. Sometimes doctors prescribe corticosteroids or other drugs that reduce your immune response.

Thyroid Disease During Pregnancy

Uncontrolled hyperthyroidism during pregnancy can lead to serious health problems in the mother and the unborn baby. During pregnancy, mild hyperthyroidism does not require treatment. More severe hyperthyroidism is treated with antithyroid medications, which act by interfering with thyroid hormone production.

Bronchiolitis
Bronchiolitis samer kareem 2,446 Views • 3 years ago

Bronchiolitis is a common lung infection in young children and infants. It causes inflammation and congestion in the small airways (bronchioles) of the lung. Bronchiolitis is almost always caused by a virus. Typically, the peak time for bronchiolitis is during the winter months. Bronchiolitis starts out with symptoms similar to those of a common cold but then progresses to coughing, wheezing and sometimes difficulty breathing. Symptoms of bronchiolitis can last for several days to weeks, even a month.

Parkinson's part 1
Parkinson's part 1 samer kareem 6,151 Views • 3 years ago

Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. In the early stages of Parkinson's disease, your face may show little or no expression, or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson's disease symptoms worsen as your condition progresses over time. Although Parkinson's disease can't be cured, medications may markedly improve your symptoms. In occasional cases, your doctor may suggest surgery to regulate certain regions of your brain and improve your symptoms.
