ATTENTION DEFICIT HYPERACTIVITY DISORDER

Attention deficit hyperactivity disorder (ADHD) is a problem of not being able to focus, being overactive, not being able control behavior, or a combination of these. For these problems to be diagnosed as ADHD, they must be out of the normal range for a person's age and development.

Causes:
ADHD usually begins in childhood, but may continue into the adult years. It is the most commonly diagnosed behavioral disorder in children. ADHD is diagnosed much more often in boys than in girls.
It is not clear what causes ADHD. A combination of genes and environmental factors likely plays a role in the development of the condition. Imaging studies suggest that the brains of children with ADHD are different from those of children without ADHD.

Symptoms of ADHD fall into three groups:
-Not being able to focus (inattentiveness)
-Being extremely active (hyperactivity)
-Not being able to control behavior (impulsivity).

Some people with ADHD have mainly inattentive symptoms. Some have mainly hyperactive and impulsive symptoms. Others have a combination of different symptom types. Those with mostly inattentive symptoms are sometimes said to have attention deficit disorder (ADD). They tend to be less disruptive and are more likely not to be diagnosed with ADHD.


Inattentive Symptoms
-Fails to give close attention to details or makes careless mistakes in schoolwork
-Has difficulty keeping attention during tasks or play
-Does not seem to listen when spoken to directly
-Does not follow through on instructions and fails to finish schoolwork or chores and tasks
-Has problems organizing tasks and activities
-Avoids or dislikes tasks that require sustained mental effort (such as schoolwork)
-Often loses toys, assignments, pencils, books, or tools needed for tasks or activities
-Is easily distracted
-Is often forgetful in daily activities.

Hyperactivity Symptoms
-Fidgets with hands or feet or squirms in seat
-Leaves seat when remaining seated is expected
-Runs about or climbs in inappropriate situations
-Has problems playing or working quietly
-Is often "on the go," acts as if "driven by a motor"
-Talks excessively.

Impulsivity Symptoms
-Blurts out answers before questions have been completed
-Has difficulty awaiting turn
-Interrupts or intrudes on others (butts into conversations or games).

PHARMACOLOGY
CNS stimulants and drugs used for ADHD:
-Atomoxetine (Strattera).
-Dexamfetamine sulphate (Dexedrine).
-Methylphenidate hydrochloride (Ritalin, Concerta XL, Equasym XL, Medikinet XL).
-Modafinil (Provigil).

ANTIDEPRESSANT DRUGS

DEPRESSION
Depression may be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us feel this way at one time or another for short periods.
Clinical depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for a longer period of time.

Symptoms of depression include:
-Low or irritable mood most of the time
-A loss of pleasure in usual activities
-Trouble sleeping or sleeping too much
-A big change in appetite, often with weight gain or loss
-Tiredness and lack of energy
-Feelings of worthlessness, self-hate, and guilt
-Difficulty concentrating
-Slow or fast movements
-Lack of activity and avoiding usual activities
-Feeling hopeless or helpless
-Repeated thoughts of death or suicide.
Low self-esteem is common with depression. It is also common to have sudden bursts of anger and a lack of pleasure from activities that normally make you happy, including sex.
The main types of depression include:
-Major depression: to be diagnosed with major depression, you must have five or more of the symptoms listed above for at least 2 weeks. Major depression tends to continue for at least 6 months if not treated. (You are said to have minor depression if you have less than five depression symptoms for at least 2 weeks. Minor depression is similar to major depression except it only has two to four symptoms.)
-Atypical depression: occurs in about a third of patients with depression. Symptoms include overeating and oversleeping. You may feel like you are weighed down and get very upset by rejection.
-Dysthymia: a milder form of depression that can last for years, if not treated.

Other common forms of depression include:
Postpartum depression: many women feel down after having a baby, but true postpartum depression is more severe and includes the symptoms of major depression.
Premenstrual dysphoric disorder: symptoms of depression occur 1 week before your menstrual period and disappear after you menstruate.
Seasonal affective disorder (SAD): occurs most often during the fall-winter season and disappears during the spring-summer season. It is most likely due to a lack of sunlight.
Depression may also alternate with mania (known as manic depression or bipolar disorder).

ANTIPSYCHOTIC DRUGS

SCHIZOPHRENIA


Schizophrenia is a serious brain illness. People who have it may hear voices that aren't there. They may think other people are trying to hurt them. Sometimes they don't make sense when they talk. The disorder makes it hard for them to keep a job or take care of themselves.

Symptoms of schizophrenia usually start between ages 16 and 30. Men often develop symptoms at a younger age than women. People usually do not get schizophrenia after age 45. There are three types of symptoms:
-Psychotic symptoms distort a person's thinking. These include hallucinations (hearing or seeing things that are not there), delusions (beliefs that are not true), trouble organizing thoughts, and strange movements.
-"Negative" symptoms make it difficult to show emotions and to function normally. A person may seem depressed and withdrawn.
Cognitive symptoms affect the thought process. These include trouble using information, making decisions, and paying attention.



No one is sure what causes schizophrenia. Your genes, environment, and brain chemistry may play a role.
There is no cure. Medicine can help control many of the symptoms. Additional treatments can help you deal with your illness from day to day. These include therapy, family education, rehabilitation, and skills training.


MANIA

Bipolar disorder is a serious mental illness. People who have it go through unusual mood changes. They go from very happy, "up," and active to very sad and hopeless, "down," and inactive, and then back again. They often have normal moods in between. The up feeling is called mania. The down feeling is depression.
The causes of bipolar disorder aren't always clear. It runs in families. Abnormal brain structure and function may also play a role.
Bipolar disorder often starts in a person's late teen or early adult years. But children and adults can have bipolar disorder too. The illness usually lasts a lifetime.

If not treated, bipolar disorder can lead to damaged relationships, poor job or school performance, and even suicide. However, there are effective treatments to control symptoms: medicine and talk therapy. A combination usually works best.

HYPNOTICS AND ANXIOLYTICS

INSOMNIA
Insomnia is trouble falling asleep, staying asleep through the night, or waking up too early in the morning. Episodes of insomnia may come and go or be long-lasting.
The quality of your sleep is as important as how much sleep you get.

Causes
Sleep habits we learned as children may affect our sleep behaviors as adults. Poor sleep or lifestyle habits that may cause insomnia or make it worse include:
-Going to bed at different times each night
-Daytime napping
-Poor sleeping environment, such as too much noise or light
-Spending too much time in bed while awake
-Working evenings or night shifts
-Not getting enough exercise
-Using the television, computer, or a mobile device in bed

The use of some medications and drugs may also affect sleep, including:
-Alcohol or other drugs
-Heavy smoking
-Too much caffeine throughout the day or drinking caffeine late in the day
-Getting used to certain types of sleep medicines
-Some cold medicines and diet pills
-Other over-the-counter or prescription medicines, herbs, or supplements

Physical, social, and mental health issues can affect sleep patterns, including:
-Bipolar disorder.
-Overactive thyroid gland.
-Waking up at night to use the bathroom.
-Feeling sad or depressed. (Often, insomnia is the symptom that causes people with depression to seek medical help.)
-Physical pain or discomfort.
-Stress and anxiety, whether it is short-term or long-term. For some people, the stress caused by insomnia makes it even harder to fall asleep.

With age, sleep patterns tend to change. Many people find that aging causes them to have a harder time falling asleep, and that they wake up more often.
Symptoms
The most common complaints or symptoms in people with insomnia are:
-Trouble falling asleep on most nights
-Feeling tired during the day or falling asleep during the day
-Not feeling refreshed when you wake up
-Waking up several times during sleep.

People who have insomnia are sometimes consumed by the thought of getting enough sleep. But the more they try to sleep, the more frustrated and upset they get, and the harder sleep becomes.

Lack of restful sleep can:
-Make you tired and unfocused, so it is hard to do daily activities.
-Put you at risk for auto accidents. If you are driving and feel sleepy, pull over and take a break.


ANXIETY
Fear and anxiety are part of life. You may feel anxious before you take a test or walk down a dark street. This kind of anxiety is useful - it can make you more alert or careful. It usually ends soon after you are out of the situation that caused it. In some people. the anxiety does not go away, and gets worse over time. They may have chest pains or nightmares. They may even be afraid to leave home. These people have anxiety disorders. Types include:
-Panic disorder.
-Obsessive-compulsive disorder.
-Post-traumatic stress disorder.
-Phobias.
-Generalized anxiety disorder.
Treatment can involve medicines, therapy or both.

BRONCHODILATORS

ASTHMA
Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air.

Symptoms of asthma include:
-Wheezing
-Coughing, especially early in the morning or at night
-Chest tightness
-Shortness of breath

Not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. Your doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. You may also have allergy tests.
When your asthma symptoms become worse than usual, it's called an asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.

COPD
COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it.

At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include:
-A cough that produces a lot of mucus
-Shortness of breath, especially with physical activity
-Wheezing
-Chest tightness

Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.

CROUP
Croup is breathing difficulty and a "barking" cough. Croup is due to swelling around the vocal cords. It is common in infants and children.

LIPID-REGULATING DRUGS AND LOCAL SCLEROSANTS

Cholesterol is a fatty substance known as a lipid and is vital for the normal functioning of the body. It is mainly made by the liver but can also be found in some foods.
Having an excessively high level of lipids in your blood (hyperlipidemia) can have an effect on your health. High cholesterol itself does not cause any symptoms, but it increases your risk of serious health conditions.


Cholesterol is carried in your blood by proteins, and when the two combine they are called lipoproteins. There are harmful and protective lipoproteins known as LDL and HDL, or 'bad' and 'good' cholesterol:
-Low-density lipoprotein (LDL): LDL carries cholesterol from your liver to the cells that need it. If there is too much cholesterol for the cells to use, it can build up in the artery walls, leading to disease of the arteries. For this reason, LDL cholesterol is known as "bad cholesterol".
-High-density lipoprotein (HDL): HDL carries cholesterol away from the cells and back to the liver, where it is either broken down or passed out of the body as a waste product. For this reason, it is referred to as "good cholesterol" and higher levels are better.


LIPID-REGULATING DRUGS

-Statins:
They are more effective than other lipid-regulating drugs at lowering LDL-cholesterol concentration but they are less effective than the fibrates in reducing triglyceride concentration. However, statins reduce cardiovascular disease events and total mortality irrespective of the initial cholesterol concentration.
-Atorvastatin (Lipitor).
-Fluvastatin (Lescol).
-Pravastatin sodium (Lipostat).
-Rosuvastatin (Crestor).
-Simvastatin (Zocor, Inegy).
-Bile acid sequestrants: used in the management of hypercholesterolaemia.
-Colesevelam hydrochloride (Cholestagel).
-Colestyramine (Questran).
-Colestipol hydrochloride (Colestid).
-Ezetimibe: inhibits the intestinal absorption of cholesterol (Ezetrol).
-Fibrates: act mainly by decreasing serum triglycerides, they have variable effects on LDL-cholesterol.
-Bezafibrate (Bezalip).
-Ciprofibrate (Modalim).
-Fenofibrate (Lipantil, Supralip).
-Gemfibrozil (Lopid).
-Nicotinic acid group:
-Acipimox: indicated for hyperlipidaemias of types IIb and IV (Olbetam).
-Nicotinic Acid: adjunt to statin in dyslipidaemia or used alone if statin not tolerated (Niaspan).
-Omega-3- fatty acid compounds:
-Omega-3-Acid Ethyl Esters: indicated for hypertriglyceridaemia (Omacor).
-Omega-3-Marine Triglycerides: adjunt in the reduction of plasma triglycerides in severe hypertriglyceridaemia (Maxepa).

LOCAL SCLEROSANTS

-Ethanolamine oleate: indicated for sclerotherapy of varicose veins.
-Sodium Tetradecyl Sulphate: indicated for sclerotherapy of varicose veins (Fibro-vein).

MYOCARDIAL INFARCTION, FIBRINOLYSIS, ANTIFIBRINOLYTIC DRUGS AND HAEMOSTATICS

MYOCARDIAL INFACTION
Most heart attacks are caused by a blood clot that blocks one of the coronary arteries. The coronary arteries bring blood and oxygen to the heart. If the blood flow is blocked, the heart is starved of oxygen and heart cells die.
The medical term for this is myocardial infarction.

Causes
A substance called plaque can build up in the walls of your coronary arteries. This plaque is made up of cholesterol and other cells.
A heart attack may occur when:
-A tear in the plaque occurs. This triggers blood platelets and other substances to form a blood a clot at the site that blocks blood from flowing to the heart. This is the most common cause of heart attack.
-A slow buildup of plaque may narrow one of the coronary arteries so that it is almost blocked.
The cause of heart attack is not always known.


Heart attack may occur:
-when you are resting or asleep
-after a sudden increase in physical activity
-when you are active outside in cold weather
-after sudden, severe emotional or physical stress, including an illness.

Symptoms
Chest pain is the most common symptom of a heart attack.
You may feel the pain in only one part of your body OR pain may move from your chest to your arms, shoulder, neck, teeth, jaw, belly area, or back.

The pain can be severe or mild. It can feel like:
-a tight band around the chest
-bad indigestion
-something heavy sitting on your chest
-squeezing or heavy pressure.

The pain most often lasts longer than 20 minutes. Rest and a medicine to relax the blood vessels (called nitroglycerin) may not completely relieve the pain of a heart attack. Symptoms may also go away and come back.

Other symptoms of a heart attack can include: anxiety, cough, fainting, light-headedness, dizziness, nause or vomiting, palpitations, shortness of breath ans sweating.

Some people (the elderly, people with diabetes, and women) may have little or no chest pain. Or, they may have unusual symptoms such as shortness of breath, fatigue, and weakness. A "silent heart attack" is a heart attack with no symptoms.


FIBRINOLYTIC DRUGS
Fibrinolytic drugs act as thrombolytics by activating plasminogento form plasmin, which degrades fibrin and so breaks up thrombi.
-Alteplase (Actilyse).
-Reteplase (Rapilysin).
-Streptokinase (Streptase).
-Tenecteplase (Metalyse).
-Urokinase.

ANTIFIBRINOLYTIC DRUGS AND HAEMOSTATICS
-Etamsylate: blood loss in menorrhagia (Dicynene).
-Tranexamic acid: it can be used to prevent bleeding or to treat bleeding associated withexcessive fibrinolysis (Cyklokapron).

Blood products:
-Antithrombin III concentrate: indicated for congenital deficiency of antithrombin III.
-Dried prothrombin complex.
-Drotrecogin alfa (activated).
-Factor VIIa (recombinant).
-Factor VIII fraction, dried.
-Factor VIII inhibitor bypassing fraction.
-Factor IX fraction, dried.
-Factor XIII fraction, dried.

ANGINA

ANGINA
Angina is chest pain or discomfort you feel when there is not enough blood flow to your heart muscle. Your heart muscle needs the oxygen that the blood carries. Angina may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw, or back.

Angina is a symptom of coronary artery disease(CAD), the most common heart disease. CAD happens when a sticky substance called plaque builds up in the arteries that supply blood to the heart, reducing blood flow.

There are three types of angina:
-Stable angina is the most common type. It happens when the heart is working harder than usual. Stable angina has a regular pattern. Rest and medicines usually help.
-Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion. It does not go away with rest or medicine. It is a sign that you could have a heart attack soon.
-Variant angina is rare. It happens when you are resting. Medicines can help.


Nitrates, calcium-channel blockers and other antianginal drugs.
1. Nitrates:
-Glyceryl Trinitrate (GTN, Coro-Nitro Pump Spray, Glytrin Spray, Nitromin, Suscard, Nitrocine, Nitronal, Deponit, Minitran, Percutol, Nitro-Dur, Transiderm-Nitro, Trintek).

HYPERTENSION AND HEART FAILURE

Hypertension
Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Hypertension is another term used to describe high blood pressure.

Blood pressure readings are given as two numbers. The top number is called the systolic blood pressure. The bottom number is called the diastolic blood pressure. For example, 120 over 80 (written as 120/80 mmHg).

One or both of these numbers can be too high.
-Normal blood pressure is when your blood pressure is lower than 120/80 mmHg most of the time.
-High blood pressure (hypertension) is when your blood pressure is 140/90 mmHg or above most of the time.
-If your blood pressure numbers are 120/80 or higher, but below 140/90, it is called pre-hypertension.

If you have heart or kidney problems, or you had a stroke, your doctor may want your blood pressure to be even lower than that of people who do not have these conditions.


Causes
Many factors can affect blood pressure, including:
-The amount of water and salt you have in your body
T-he condition of your kidneys, nervous system, or blood vessels
-Your hormone levels

You are more likely to be told your blood pressure is too high as you get older. This is because your blood vessels become stiffer as you age. When that happens, your blood pressure goes up. High blood pressure increases your chance of having a stroke, heart attack, heart failure, kidney disease, or early death.
You have a higher risk of high blood pressure if:
-You are African American
-You are obese
-You are often stressed or anxious
-You drink too much alcohol (more than 1 drink per day for women and more than 2 drinks per day for men)
-You eat too much salt
-You have a family history of high blood pressure
-You have diabetes
-You smoke.

Most of the time, no cause of high blood pressure is found. This is called essential hypertension.

High blood pressure that is caused by another medical condition or medicine you are taking is called secondary hypertension. Secondary hypertension may be due to:
-Chronic kidney disease
-Disorders of the adrenal gland
-Hyperparathyroidism
-Pregnancy or preeclamsia 
-Medications such as birth control pills, diet pills, some cold medicines, and migraine medicines
-Narrowed artery that supplies blood to the kidney (renal artery stenosis).


Symptoms
Most of the time, there are no symptoms. For most patients, high blood pressure is found when they visit their doctors or have it checked elsewhere.
Because there are no symptoms, people can develop heart disease and kidney problems without knowing they have high blood pressure.


Malignant hypertension is a dangerous form of very high blood pressure. Symptoms include:
-Severe headache
-Nausea or vomiting
-Confusion
-Vision changes
-Nosebleed.

Heart failure
Heart failure is a complex syndrome characterised by reduced heart efficiency and resultant haemodynamic and neurohormal responses (Poole-Wilson 1985).
Heart failure is caused by a number of pathological conditions. Some causes are reversible, but others are not.
Causes of heart failure:
-Ischaemic heart disease.
-Hypertension.
-Arrythmias.
-Valve disorders.
-Myocarditis.
-Alcohol-induced cardiomyopathy (heart muscle abnormalities).
-Chemotherapy-induced cardiomyopathy.
-Genetic cardiomyopathies.
-Amyloidosis.
-Sarcoidosis.
-Metabolic disorders.
(*This is a shortened list).

Patients can have acute heart failure without underlying chronic heart failure but more commonly acute presentations are due to destabilisation of chronic disease.
Patients who are well managed can have a good quality of life and extend their prognosis, but heart failure is unpredictable and difficult to prognosticate for individual patients.

Diagnosis
Heart failure should be diagnosed using the pathway in the European Society of Cardiology (ESC) guidelines (McMurray et al 2012).
Once diagnosis is confirmed the severity of the symptoms can be expressed using the New York Heart Association (NYHA) classification.

ANTI-ARRHYTMIC DRUGS AND BETA-ADRENOCEPTOR BLOCKING DRUGS

ARRHYTHMIAS
An arrhythmia is a disorder of the heart rate (pulse) or heart rhythm. The heart can beat too fast (tachycardia), too slow (bradycardia), or irregularly.

Causes
Arrhythmias are caused by problems with the heart's electrical conduction system:
-Abnormal (extra) signals may occur.
-Electrical signals may be blocked or slowed.
-Electrical signals travel in new or different pathways through the heart.

Some common causes of abnormal heartbeats are:
-Abnormal levels of potassium or other substances in the body
-Heart attack, or a damaged heart muscle from a past heart attack
-Heart disease that is present at birth (congenital)
-Heart failure or an enlarged heart
-Overactive thyroid gland
Arrhythmias may also be caused by some substances or drugs, including: alcohol, caffeine, or stimulant drugs, heart or blood pressure medicines, cigarette smoking (nicotine), drugs that mimic the activity of your nervous system and medicines used for depression or psychosis.
Sometimes medicines used to treat one type of arrhythmia will cause another type of abnormal heart rhythm.

Some of the more common abnormal heart rhythms are:
-Tachycardia: supraventricular tachycardia (SVT) or ventricular tachycardia (ventricular fibrillation).
-Bradycardia: sinus node dysfunction or heart block.

Other classification:                                                                                                                           Arrhythmias originating in the Atria:
-Atrial fibrillation.
-Atrial flutter.
-Supraventricular tachycardias (PSVT).
-Wolff-Parkinson-White syndrome.
-Premature supraventricular contraction or premature atrial contraction (PAC).
-Sick sinus syndrome.
-Sinus arrhythmia.
-Sinus tachycardia.
-Multifocal atrial tachycardia.
 Arrhythmias originating in the Ventricles:
-Premature ventricular contraction (PVC)
-Ventricular Fibrillation
-Ventricular tachycardia.



Symptoms
An arrhythmia may be present all of the time or it may come and go. You may or may not feel symptoms when the arrhythmia is present. Or, you may only notice symptoms when you are more active.
Symptoms can be very mild, or they may be severe or even life-threatening.
Common symptoms that may occur when the arrhythmia is present include: chest pain, fainting, light-headedness, dizziness, paleness, shortness of breath or sweating.

Treatment
When an arrhythmia is serious, you may need urgent treatment to restore a normal rhythm. This may include:
-Electrical "shock" therapy (defibrillation or cardioversion)
-Implanting a short-term heart pacemaker
-Medicines given through a vein (intravenous) or by mouth.
Sometimes, better treatment for your angina or heart failure will lower your chance of having an arrhythmia.
Medicines called anti-arrhythmic drugs may be used:
-To prevent an arrhythmia from happening again
-To keep your heart rate from becoming too fast or too slow
Other treatments to prevent or treat abnormal heart rhythms include: cardiac ablation, implantable cardiac defibrillator or a pacemaker.

POSITIVE INOTROPIC DRUGS AND DIURETICS - OEDEMA

POSITIVE INOTROPIC DRUGS
Positive inotropic drugs increase the force of contraction of the myocardium.
1. Cardiac glycosides: Cardiac glycosides are most useful in the treatment of supraventricular tachycardias, especially for controlling ventricular response in persistent atrial fibrillation.
-Digoxin: indicated for heart failure and supraventricular arrhtythmias (Lanoxin).


-Digitoxin: same indications as digoxin.
-Digoxin-specific antibody: indicated for the treatment of known or strongly suspected digoxin or digitoxin overdosage. (Digibind).
2. Phosphodiesterase inhibitors:
-Enoximone: indicated for congestive heart failure where cardiac output reduced and filling pressures increased. (Perfan).
-Milrinone: for short-term treatment of severe congestive heart failure unresponsive to conventional maintenance therapy and acute heart failure, including low output states following heart surgery (Primacor).

OEDEMA
Oedema is the medical term for fluid retention in the body.
The build-up of fluid causes affected tissue to become swollen. The swelling can occur in one particular part of the body – for example, as the result of an injury – or it can be more general.
This is usually the case with oedema that occurs as a result of certain health conditions, such as heart failure or kidney failure.
As well as swelling or puffiness of the skin, oedema can also cause:
-skin discolouration
-areas of skin that temporarily hold the imprint of your finger when pressed (known as pitting oedema)
-aching, tender limbs
-stiff joints
-weight gain or weight loss
-raised blood pressure and pulse rate.

Types of oedema
Oedema can occur anywhere in the body, but it's most common in the feet and ankles. This is known asperipheral oedema.
Other types of oedema include:
-cerebral oedema – affecting the brain
-pulmonary oedema – affecting the lungs
-macular oedema – affecting the eyes.
Idiopathic oedema is a term used to describe cases of oedema where a cause can't be found.

Causes
It's normal to have some swelling in your legs at the end of the day, particularly if you've been sitting or standing for long periods, inmobility and standing for long periods are the most common causes of oedema in the legs.
Oedema is often a symptom of an underlying health condition. It can occur as a result of the following conditions or treatments:
-pregnancy
-kidney, chronic lung, thyroid or liver disease
-heart failure
-malnutrition
-medication, such as corticosteroids, medicine for hypertension or the contraceptive pill.
Other possible causes include: a blood clot, severe varicose veins, a leg injury or leg surgery, burns to the skin.

Treatment
Oedema usually clears up by itself. However, your GP may suggest some self-help measures to reduce fluid retention, such as:
-losing weight (if you're overweight)
-taking regular exercise.
-raising your legs three to four times a day to improve your circulation
-avoiding standing for long periods of time

If an underlying condition is causing the fluid imbalance, it should clear up after the condition has been diagnosed and treated.


DIURETICS
1. Thiazides and related diuretics:
-Bendroflumethiazide: indicated for oedema and hypertension.
-Chlortalidone: indicated for ascites due to cirrhosis in stable patients, oedema due to nephrotic syndrome, hypertension, mild to moderate chronic heart failure and diabetes insipidus. (Hygroton).

INTERVENCIÓN EN EL TABAQUISMO

Captación: historia del fumador
En primer lugar se debe realizar la historia tabáquica, desde el punto de vista médico, psicológico y de enfermería. Los datos que se aconseja reflejar en la anamnesis tabáquica son:
-edad de inicio
-número de cigarrilos/día consumidos
-paquetes consumidos (número de cigarrilos consumidos al día multiplicados por el número de años que lleva consumiendo esa cantidad de tabaco y dividido por 20)
-años de fumador
-número de intentos previos
-fecha del último intento
-tiempo máximo de abstinencia
-causas de recaída
-tratamiento llevado a cabo
Toda esta documentación permitirá obtener información sobre el consumo y personalizar posteriormente el seguimiento.

DIAGNÓSTICO DEL PACIENTE FUMADOR: fases del abandono del tabaco.
En segundo lugar se va a realizar un diagnóstico del fumador. Prochazca y DiClemente, en 1992, definieron cinco fases en el proceso de abandono del tabaco precontemplación, contemplación, preparación, acción y mantenimiento. Los fumadores se encuentran en una u otra dependiendo de su mayor o menor motivación para dejar de fumar y de su mayor o menor inclinación a hacer un intento serio de abandono. Se recomienda investigar la fase de abandono en la que se encuentra cada fumador, pues la actitud terapéutica deberá venir determinada por dicha fase, y el conocimiento de la etapa de abandono permitirá instaurar el tratamiento más adecuado para cada fumador. 



1. Fase de precontemplación: son aquellos pacientes que no tienen intención de dejar de fumar en un periodo superior a seis meses. El paciente se percibe a sí mismo como fumador. Generalmente son personas jóvenes y sanas que todavía no han visto afectada su salud por síntomas preocupantes relacionados con el tabaco.
Intervención: motivar al paciente para que considere la posibilidad de dejarlo. Para ello hay que facilitarle materiales que contribuyan a aumentar su motivación. Sin una intervención planificada, las personas pueden permanecer en esta fase durante mucho tiempo.

2. Fase de contemplación: son aquellos pacientes que se plantean dejar de fumar en un periodo aproximado de seis meses. Comienza a producirse un cambio de actitud en el fumador en su relación con el tabaco. Aparece una disonancia entre su conducta actual y el comportamiento deseado. El fumador piensa que sería bueno dejar de fumar pero no se lo plantea a corto plazo. En general, este cambio se debe a la percepción de los primeros síntomas negativos sobre su salud derivados del consumo del tabaco.
Intervención: deben recibir información personalizada sobre las ventajas de dejar el consumo del tabaco, así como materiales educativos, consejos sobre cómo dejarlo e información sobre opciones de tratamiento disponibles. Informar de los beneficios que se obtienen al abandonar el tabaco y entregar por escrito.

3. Fase de preparación: son aquellos pacientes que quieren hacer un intento serio de abandono en el próximo mes. El fumador ha personalizado las ventajas de dejar de fumar y está motivado para hacer el esfuerzo que implica dejar el tabaco.
Intervención: todo fumador que se encuentre en esta fase debe ser objeto de una intervención mínima sistematizada (IMS).
Interesante artículo sobre el IMS: http://www.lasdrogas.info/doc/fuentes/tabaquismo_interv_min.pdf

4. Fase de acción: son aquellos pacientes que han abandonado el hábito recientemente en un periodo igual o menor a seis meses. La persona ha tomado la decisión de dejar de fumar, ha pasado del propósito a la acción. Sólo un reducido número de personas lo consiguen en el primer intento. Suele ser un periodo más o menos largo, de fases alternantes de consumo y abstinencia.
Intervención: seguimiento del fumador. Algunos de los puntos más importantes a valorar en el seguimiento son: reforzar la abstinencia, el cumplimiento de las pautas establecidas, valoración del estado físico y psicológico y consejos para evitar recaídas-

5. Fase de mantenimiento: son aquellos pacientes que abandonaron el hábito hace más de seis meses y menos de un año. Se pretende evitar recaídas.
Intervención: seguimiento del fumador.

6. Fase de recaída: son aquellos pacientes que han vuelto a fumar. Puede aparecer en cualquier momento desde que el paciente ha dejado de fumar.
Intervención: evitar la desmoralización y el descenso de la autoestima y normalizar la recaída como parte del proceso y ayudarle a entrar de nuevo en el ciclo de cambio.


ESTUDIO DE LA MOTIVACIÓN
El grado de motivación se puede evaluar de una forma sencilla mediante el test de motivación de Richmond.


Según la puntuación obtenida se obtendrá un grado determinado de motivación. Motivación baja si es menor de 6 puntos, motivación moderada si está entre 7 y 9 puntos y motivación alta si es de 10 puntos.
