Published under Health Articles Monday, September 13th, 2010 When we feel stress and are anxious over a new job, an old relationship, or even just the everyday conundrums we all face from time to time, it can be beneficial to the nerves to take some vitamins minerals and added supplements that have proven benefit for relief of stress and anxiety. By adding them to our daily diet we can be assured of eliminating those frayed nerves and feeling calm and self assured. While the stress relieving vitamins are not necessarily miracle workers you will be amazed at how effective they can be. Commonly people worry to the point of becoming physically ill when faced with financial or personal problems beyond control. While popping a pill or two is the most popular way to cope, they can provide only a short term means of relief and many stress reducing sedatives can even become habit forming. Magnesium and other natural ingredients relieve anxiety Magnesium is one of the most effective natural ingredients to calm the nerves while relieving stress. Magnesium is a mineral that cannot be manufactured in the human body yet is extremely valuable to our kidneys, brain, heart, and nervous…

Latex allergy

2 Comments

may be seen as the latest ‘issue’; but it isn’t going to just go away. Introduction It has been estimated that up to 30% of the population has atopic allergy and 43% of NHS staff suffer from some sort of skin irritation. Within these groups a latex sensitivity of 10% has been calculated – which is 3% or 1.5 million of the British population who are at risk.(Turner, Occupational Health 1997; 49:2, 57-60) (Bandolier I) The AIDS epidemic of the 1980s prompted a massive increase in the use of latex gloves for healthcare workers who are increasingly at risk due to the increased use of ‘economic’ latex gloves and enhanced sensitivity from other latex products also encountered in daily work. (Packham) (Bandolier I) Sometimes sensitivity is encountered from the chemical accelerators used in the manufacturing process. It should be noted that Glove powder is just a carrier of latex proteins not the primary allergen. Likewise the strength of detergent used in hand washing ‘soap’ is a critical factor – especially if the frequency is high and no emollient or skin aftercare treatments are provided; broken skin may lead to further sensitisation via the ingress of allergens. (Charous) This phenomenon also…

celiac disease

1 Comment

Celiac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. People who have celiac disease cannot tolerate gluten, a protein in wheat, rye, and barley. Gluten is found mainly in foods but may also be found in everyday products such as medicines, vitamins, and lip balms. The small intestine is shaded above. When people with celiac disease eat foods or use products containing gluten, their immune system responds by damaging or destroying villi—the tiny, fingerlike protrusions lining the small intestine. Villi normally allow nutrients from food to be absorbed through the walls of the small intestine into the bloodstream. Without healthy villi, a person becomes malnourished, no matter how much food one eats. Villi on the lining of the small intestine help absorb nutrients. Celiac disease is both a disease of malabsorption—meaning nutrients are not absorbed properly—and an abnormal immune reaction to gluten. Celiac disease is also known as celiac sprue, nontropical sprue, and gluten-sensitive enteropathy. Celiac disease is genetic, meaning it runs in families. Sometimes the disease is triggered—or becomes active for the first time—after surgery, pregnancy, childbirth, viral infection, or severe emotional stress. What are the symptoms of celiac…

About Pinkeye

1 Comment

Conjunctivitis, commonly known as pinkeye, is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and the inner surface of the eyelids. While pinkeye can be alarming because it may make the eyes extremely red and can spread rapidly, it’s a fairly common condition and usually causes no long-term eye or vision damage. But if your child shows symptoms of pinkeye, it’s important to see a doctor. Some kinds of pinkeye go away on their own, but other types require treatment. Causes Pinkeye can be caused by many of the bacteria and viruses responsible for colds and other infections, — including ear infections, sinus infections, and sore throats — and by the same types of bacteria that cause the sexually transmitted diseases (STDs) chlamydia and gonorrhea. Pinkeye also can be caused by allergies. These cases tend to happen more frequently among kids who also have other allergic conditions, such as hay fever. Triggers of allergic conjunctivitis include grass, ragweed pollen, animal dander, and dust mites. Sometimes a substance in the environment can irritate the eyes and cause pinkeye; for example, chemicals (such as chlorine and soaps) and air pollutants (such as smoke and…

As of 2009, 300 million people were affected worldwide.[7] In 2009 asthma caused 250,000 deaths globally.[7] Despite this, with proper control of asthma with step down therapy, prognosis is generally good.

Anaphylaxis

From Wikipedia, the free encyclopedia (Redirected from Anaphylactic shock) Jump to: navigation, search Anaphylaxis Classification and external resources A rash on the back of a person with anaphylaxis. ICD-10 T78.2 DiseasesDB 29153 eMedicine med/128 MeSH D000707 Anaphylaxis is an acute multi-system severe type I hypersensitivity reaction. The term comes from the Greek words ἀνά ana (against) and φύλαξις phylaxis (protection).[1] Due in part to the variety of definitions, between 1% and 15% of the population of the United States can be considered “at risk” for having an anaphylactic reaction if they are exposed to one or more allergens. Of those people who actually experience anaphylaxis, up to 1% may die as a result.[2] Anaphylaxis results in approximately 1,500 deaths per year in the U.S.[3][4] In England, mortality rates for anaphylaxis have been reported as up to 0.05 per 100,000 population, or around 10-20 a year.[5] Anaphylactic reactions requiring hospital treatment appear to be increasing, with authorities in England reporting a threefold increase between 1994 and 2004.[6] Based on the pathophysiology, anaphylaxis can be divided into “true anaphylaxis” and “pseudo-anaphylaxis” or “anaphylactoid reaction.” The symptoms, treatment, and risk of death are the same; however, “true” anaphylaxis is caused by degranulation of…

Allergic rhinitis Pollen grains from a variety of common plants can cause hay fever. ICD-10 J30. ICD-9 477 OMIM 607154 DiseasesDB 31140 MedlinePlus 000813 eMedicine ent/194 med/104, ped/2560 MeSH D012221 Allergic rhinitis, pollenosis or hay fever is an allergic inflammation of the nasal airways. It occurs when an allergen such as pollen or dust is inhaled by an individual with a sensitized immune system, and triggers antibody production. The specific antibody is immunoglobulin E (IgE) which binds to mast cells and basophils containing histamine. IgE bound to mast cells are stimulated by pollen and dust, causing the release of inflammatory mediators such as histamine (and other chemicals).[1] This causes itching, swelling, and mucus production. Symptoms vary in severity between individuals. Very sensitive individuals can experience hives or other rashes. Particulate matter in polluted air and chemicals such as chlorine and detergents, which can normally be tolerated, can greatly aggravate the condition.

Reye’s Syndrome

12 Comments

Definition Reye’s syndrome is a disorder that primarily affects the liver and brain. It attacks the nervous system very quickly and can cause death Description Reye’s syndrome primarily affects children and teenagers. In almost all cases, it follows a viral illness, such as a cold (see common cold entry), the flu (see influenza entry), or chickenpox (see chickenpox entry). The disorder can affect any organ in the body, but its most serious effects occur in the brain and the liver. As the disorder develops, it attacks the body’s nervous system. It produces symptoms such as listlessness, confusion, seizures, and coma. In extreme cases, it can lead to death. Reye’s syndrome is a rare disorder. It was first discovered in the early 1970s. The number of cases of Reye’s syndrome rose slowly until 1980. In that year, 555 cases of the disorder were diagnosed. Researchers had learned at that point that children who are given aspirin are at risk for Reye’s syndrome. Doctors began to warn parents against the use of aspirin with sick children. As a result of those warnings, the number of cases of Reye’s syndrome began to fall. By the late 1990s the condition was very rare in…

بسم اللله الرحمن الرحيم تعريف الجلوكوما  المياه الزرقاء.. عبارة عن ارتفاع فى ضغط العين أكثر من المعدل الطبيعى يؤدى إذا لم يعالج إلى تدمير العصب البصرى، وينتج عنه فقد البصر. ما هو ضغط العين الطبيعى؟ العين مثل الكرة لابد لها من ضغط داخلها لتحتفظ الكرة بشكلها، وتقوم بوظيفتها، مثل إطار السيارة لابد أن يكون داخله “ضغط” لكى يحتفظ الإطار بشكله ويقوم بوظيفته، فإذا قل الضغط داخل الكرة أو داخل إطار السيارة فستفقد شكلها، ولا تقوم بالغرض التى صنعت من أجله، كذلك إذا زاد الضغط داخل إطار السيارة أكثر مما يحتمل أو تحتمل، فقد تنفجر الكرة أو ينفجر إطار السيارة، كذلك كرة أو مقلة العين، إذا قل الضغط بها فقد يحدث بها مضاعفات قد تؤثر على النظر، وكذلك إذا زاد الضغط داخلها، فقد يؤدى ذلك فى النهاية إلى فقد النظر. كيف يمكن أن أعرف أن ضغط عينى طبيعى أو غير طبيعى؟ عادة لا يشعر الإنسان بضغط عينيه أى لا يستطيع أن يقدر إذا ما كان ضغط عينه عالياً أو منخفضاً.. ولكن طبيب العيون هو الذى يستطيع قياس ذلك بأجهزة خاصة. إذن هل يلزم كل شخص أن يذهب لطبيب العيون لقياس ضغط العين؟ للإجابة عن هذا السؤال يلزم التأكيد على النقاط الآتية: – من الضرورى قياس ضغط العين عند أى استشارة طبية…

Albinism

2 Comments

Albino African Penguin An albino baby girl in an orphanage in Malawi. Albinism is a condition some people and animals are born with. This condition is caused by a lack of pigment (color) in their hair, eyes, and skin. A person or animal with albinism is sometimes called an albino, but many people prefer to be called a “person with albinism”. People with albinism usually have white or light blonde hair and very fair skin. Their eyes are blue, or rarely pink-ish. People with albinism in reality do have some problems including bad vision and getting sunburn easily. All of these problems are because people with alibinism have little or no pigments in their eyes, skin and hair.[1] Vision problems in albinism include nystagmus (irregular fast movements of the eyes), strabismus (where the eyes fail to balance) and refractory errors (like being near-sighted or far-sighted). Albino animals are easily attacked by predators because they cannot hide themselves like the non-albino members of their species.[needs proof] Genetics of albinism  Albinism is a hereditary condition. It is usually inherited in an autosomal recessive pattern; it means, both parents should carry the albinism gene to have a child with albinism.[1]  Famous people with albinism …
