BuLiMiA....


Bulimia is an illness defined by food binges, or recurrent episodes of significant overeating, that are accompanied by a sense of loss of control. The affected person then uses various methods -- such as vomiting or laxative abuse -- to prevent weight gain.

In bulimia, eating binges may occur as often as several times daily for many months. These binges cause a sense of self-disgust, which leads to compensatory behaviors like self-induced vomiting or excessive exercise. A person with bulimia may also abuse laxatives, diuretics, or enemas in order to prevent weight gain.

Many more women than men have bulimia, and the disorder is most common in adolescent girls. The affected person is usually aware that her eating pattern is abnormal and may experience fear or guilt associated with the binge-purge episodes.

The exact cause of bulimia is unknown, but factors thought to contribute to its development are family problems, perfectionist personality, and an overemphasis on physical appearance. Bulimia may also be associated with depression.

In certain neurological or medical conditions, there can be disturbed eating behavior, but the essential psychological feature of bulimia, the extreme concern with body shape and weight, is not present. Organic causes for bulimia are being investigated. There is evidence that bulimia and other eating disorders may be related to abnormalities in levels of chemical messengers (neurotransmitters) within the brain, specifically the neurotransmitter serotonin. Other studies of people with bulimia have found alterations in metabolic rate, decreased perceptions of satiety, and abnormal neuroendocrine regulation (the process by which the nervous system interacts with production of hormones and hormone-like substances).

Anxiety

Generalized anxiety disorder or GAD is characterized by excessive, exaggerated anxiety and worry about everyday life events. Symptoms of GAD include: Excessive, ongoing worry and tension, An unrealistic view of problems, Restlessness or a feeling of being "edgy", Irritability, Muscle tension, Headaches, Sweating, Difficulty concentrating, Nausea, The need to go to the bathroom frequently, Tiredness, Trouble falling or staying asleep, Trembling, Being easily startled.

The exact cause of GAD is not fully known, but a number of factors—including genetics, brain chemistry and environmental stresses—appear to contribute to its development.

Neural circuitry involving the amygdala and hippocampus is thought to underlie anxiety (Rosen & Schulkin, 1998). When confronted with unpleasant and potentially harmful stimuli such as foul odors or tastes, PET-scans show increased bloodflow in the amygdala (Zald & Pardo, 1997; Zald, Hagen & Pardo, 2002). In these studies, the participants also reported moderate anxiety. This might indicate that anxiety is a protective mechanism designed to prevent the organism from engaging in potentially harmful behaviors.

Effective treatments for anxiety disorders are available, and research is yielding new, improved therapies that can help most people with anxiety disorders lead productive, fulfilling lives.

Some research has strongly suggested that treating anxiety in cancer patients improves their quality of life. The treatment generally consists of counseling, relaxation techniques or pharmacologically with benzodiazepines.

Malnutrition..

Malnutrition occurs when you do not get enough calories or nutrients to keep you healthy. Nutrients are protein, fat, carbohydrates, vitamins and minerals. Malnutrition may make your body weak.

Malnutrition is not the same thing as hunger, although they often go together. People who are malnourished lack the nutrients needed for proper health and development. Someone can be malnourished for a long or short period of time, and the condition may be mild or severe. People who are malnourished are more likely to get sick and, in severe cases, may even die.

People who don't get enough food often experience hunger, and hunger can lead to malnutrition over the long term. But someone can become malnourished for reasons that have nothing to do with hunger. Even people who have plenty to eat may be malnourished if they don't eat food that provides the right nutrients, vitamins, and minerals.

Indications of malnutrition depend on which nutritional deficiencies a child has, although they can include : fatigue and low energy, dizziness, poor immune function (which can hamper the body's ability to fight off infections), dry, scaly skin, swollen and bleeding gums, decaying teeth, slowed reaction times and trouble paying attention, underweight , poor growth, muscle weakness, bloated stomach, osteoporosis, or fragile bones that break easily, problems with organ function

Treatment for malnutrition depends on the cause. You will need to work closely with your caregiver during your treatment. Treatment for malnutrition may include increasing the calories and nutrients in your diet.

You may need to increase the calories and nutrients in your diet by doing one or more of the following:

  • Eat large meals and snacks between meals.

  • Eat small meals often throughout the day if you have trouble eating large meals.

  • Eat or drink a nutrition supplement if you have trouble eating the right kinds and amounts of food.

  • You may need to take vitamin or mineral supplements if your body is low in vitamins and minerals. Your caregiver may treat you with medicines if you have a health problem that is causing your malnutrition.

  • If you cannot buy or prepare the right kinds of foods, talk to your caregiver. Ask for information about community programs that can help you.

You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.


Psoriasis...

Psoriasis is an inflammatory skin condition. Psoriasis is a chronic, meaning lifelong, condition because there is currently no cure. People often experience flares and remissions throughout their life. Controlling the signs and symptoms typically requires lifelong therapy.

Plaque psoriasis is the most common type of psoriasis. About 80% of people who develop psoriasis have plaque psoriasis, which appears as patches of raised, reddish skin covered by silvery-white scale. These patches, or plaques, frequently form on the elbows, knees, lower back, and scalp. The other types are guttate psoriasis (small, red spots on the skin), pustular psoriasis (white pustules surrounded by red skin), inverse psoriasis (smooth, red lesions form in skin folds), and erythrodermic psoriasis (widespread redness, severe itching, and pain).

Research shows that the signs and symptoms of psoriasis usually appear between 15 and 35 years of age. About 75% develop psoriasis before age 40. However, it is possible to develop psoriasis at any age. After age 40, a peak onset period occurs between 50 and 60 years of age.

Researchers now believe that psoriasis is an immune-mediated condition. This means the condition is caused by faulty signals in the body’s immune system. It is believed that psoriasis develops when the immune system tells the body to over-react and accelerate the growth of skin cells. Normally, skin cells mature and are shed from the skin’s surface every 28 to 30 days. When psoriasis develops, the skin cells mature in 3 to 6 days and move to the skin surface. Instead of being shed, the skin cells pile up, causing the visible lesions.

Researchers have identified genes that cause psoriasis. These genes determine how a person’s immune system reacts. These genes can cause psoriasis or another immune-mediated condition, such as rheumatoid arthritis or type 1 diabetes. The risk of developing psoriasis or another immune-mediated condition, especially diabetes or Crohn’s disease, increases when a close blood relative has psoriasis.

Some people who have a family history of psoriasis never develop this condition. Research indicates that a “trigger” is needed. Stress, skin injuries, a strep infection, certain medications, and sunburn are some of the known potential triggers. Medications that can trigger psoriasis are anti-malarial drugs, beta-blockers (medication used to treat high blood pressure and heart conditions), and lithium. Dermatologists have seen psoriasis suddenly appear after a person takes one of these medications, gets a strep infection, or experiences another trigger.

With the emergence of several new therapies, including the biologic agents, more people are experiencing substantial improvements and reporting a greatly improved quality of life.


"SINUSITIS"

Sinusitis is an inflammation of the paranasal sinuses, which may or may not be as a result of infection, from bacterial, fungal, viral, allergic or autoimmune issues. Newer classifications of sinusitis refer to it as rhinosinusitis, taking into account the thought that inflammation of the sinuses cannot occur without some inflammation of the nose as well (rhinitis). Sinusitis can be acute (going on less than four weeks), subacute (4-12 weeks) or chronic (going on for 12 weeks or more).

Factors which may predispose to developing sinusitis include: allergies; structural problems such as, for example, a deviated septum, small sinus ostia; smoking; nasal polyps; carrying the cystic fibrosis gene (research is still tentative); prior bouts of sinusitis as each instance may result in increased inflammation of the nasal or sinus mucosa and potentially further narrow the openings.

Treatment of Acute sinusitis: Therapeutic measures range from the medicinal to the traditional and may include nasal irrigation or jala neti using a warm saline solution, hot drinks including tea and chicken soup, inhaling steam, over-the-counter decongestants and nasal sprays, and getting plenty of rest. Analgesics (such as aspirin, paracetamol (acetaminophen) or ibuprofen) can be used, but caution must be employed to make sure the patient does not suffer from aspirin-exacerbated respiratory disease (AERD) as this could lead to anaphylaxis.

Treatment of Chronic sinusitis: Simple measures, Medical approaches, Surgical Approach

You can lower your risk of getting sinusitis by making some simple changes in your home environment. Try using a humidifier during cold weather to stop dry, heated air from irritating your sinuses, which can make them more susceptible to infection. Clean the humidifier regularly because mold, which can trigger allergies in some people, forms easily in moist environments.

What Can I Do to Help Myself Feel Better?

If your doctor has prescribed antibiotics or any other medications, be sure to follow the directions carefully. Sinusitis can be difficult to get rid of otherwise and can easily return if it's not fully treated the first time. Even if you feel better, it's important to keep taking your antibiotics until you've finished the course prescribed by your doctor. This helps to kill all of the bacteria causing the infection.
