If you are experiencing chest pain other than heartburn, refer to the chapter on Chest Pain for more information. If your pain is centered more in your abdomen, see the chapter on Abdominal Pain for more information. Your Doctor Visit What your doctor will ask you about: anxiety, depression, weight loss, weakness, abdominal pain, nausea, vomiting blood, tarry stools, results of any recent tests of the insides of your stomach, any suc- cesses with previous treatments or diets. Your doctor will want to know if you or anyone in your family has had any of these conditions: abdominal surgery, liver disease, arthritis, chronic lung disease, alcoholism, ulcer disease. Your doctor will want to know when and how you first noticed your heartburn, and how many times it has recurred. Some important factors to consider with ulcers caused by heartburn: • Ulcers are caused by the movement of stomach acid up into and through the esophagus, which connects the throat to the stom- ach. Over time, this movement of acid can lead to ulcer, or irri- tation of the stomach or intestinal lining. To keep this from happening, your doc- tor may ask you to: • Limit your intake of caffeine, cigarettes, alcohol, and cer- tain medications. Heatstroke What it feels like: collapse during extreme heat, sometimes leading to delirium or coma. Someone with a mild form of heatstroke, known as heat prostration, will appear faint, have cold and clammy skin, and have a slight fever. If a person with heatstroke falls into a coma, becomes delirious, or has hot and dry skin and a temperature of more than 103 degrees F, seek medical help immediately. Your Doctor Visit What your doctor will ask you about: headache, changes in think- ing, loss of consciousness, nausea, vomiting, diarrhea, decreased urine output, sweating, cold skin, muscle cramps, bleeding. Your doctor will want to know if you or anyone in your family has had any of these conditions: alcoholism, heart disease, high blood pressure, diabetes. Your doctor will want to know how long you were in a hot environ- ment, the temperature of the environment, your temperature at the time of collapse, and what you were doing when you collapsed. Your doctor will do a physical examination including the fol- lowing: temperature, breathing rate, blood pressure, pulse, thorough exam of your reflexes and movement, checking skin for sweating, color, and warmth. RISK FACTOR WHAT IS IT YPICAL SYMPTOMS Dehydration Not drinking enough Dry mouth, producing little water or no urine, sunken eyes, more common in people taking blood pressure med- ication or drinking alcohol Inadequate An inability to cool Lack of sweating when hot, sweating down by sweating more common in the eld- erly, diabetics, those with high cholesterol, people wearing too much clothing or engaging in excessive exercise, or people taking anticholinergic medica- tions such as Benadryl and Cogentin, or phenoth- iazines such as the antipsy- chotic Haldol Heavy Drinking (Alcohol) What it is: your drinking patterns become a problem when you expe- rience withdrawal if you stop drinking alcohol (see below), you devel- op an illness related to drinking, or it interferes with your social or work life; drinking to excess – a six-pack of beer in one sitting, or a fifth of a gallon of whiskey, for example, without becoming drunk – is also probably a sign of problem drinking. For example, if you answer “yes” to any of the following ques- tions, you may have a drinking problem: 1. Have you ever had a drink when you wake up, to “steady your nerves” or cure a hangover? Your doctor will also want to know if you or anyone in your fam- ily has had any of these conditions: seizures, delirium after cutting 119 Copyright © 2004 by The McGraw-Hill Companies, Inc. Your doctor will do a physical examination including the fol- lowing: temperature, pulse, blood pressure, thorough skin examina- tion, tests of memory, pushing on your abdomen, checking your limbs for tremors or shakiness, tests of brain function involving bal- ance, eye movements, and reflexes. PROBLEM WHAT IS IT YPICAL SYMPTOMS Tremulousness Trembling or shaking Irritability, flushed skin, stomach upset, sleepiness, occurs after several days of drinking Delirium Delirium that occurs Fever, confusion, tremor, tremens when you stop drinking hallucinations, sweating, dilated pupils Seizures Convulsions Occur within 2 days of when you stop drinking Cerebellar A type of brain disorder Unsteadiness, abnormal degeneration eyeball movements, unco- ordinated gait Wernicke- A brain disorder caused Confusion, memory loss, Korsakoff by a lack of thiamine disorientation, abnormal psychosis (vitamin B1) eyeball movements Neuropathy Nerve damage in the Unsteadiness, numbness or extremities burning in feet or hands Hiccough What it feels like: an involuntary and rapid intake of breath accom- panied by tightness in the abdomen, often persistent. Most cases of hiccoughs occur in people who are in otherwise perfect health, often the result of eating too quickly. Your Doctor Visit What your doctor will ask you about: abdominal pain, weakness, chest pain, new cough or change in cough pattern, trouble swallow- ing, anxiety. Your doctor will want to know if you or anyone in your family has had any of these conditions: alcoholism, kidney disease, liver disease, nervous system disease. CAUSE WHAT IS IT YPICAL SYMPTOMS Rapid eating Eating too quickly Otherwise healthy Gastroenteritis Infection of the stomach Nausea, vomiting, diar- rhea, cramping, muscle aches, slight fever Gastric An expansion of the “Gas,” discomfort distention (see stomach, either by food chapter on or gas Bloating) Lung tumor Unchecked, abnormal Change in cough patterns, growth of cells in the coughing up blood, chest lungs ache, more common in cigarette smokers Advanced renal Inability of the kidneys Pallor, gradual lapse into failure to function properly coma, history of kidney disease Encephalitis Inflammation or infection Fever, nausea, vomiting, of the brain stiff neck, headache, grad- ual lapse into coma Hoarseness What it feels like: a dry, scratchy voice. The most common cause of hoarseness that has lasted less than 2 weeks is inflammation in the voice box, often accompanied by a cold and sore throat. Your Doctor Visit What your doctor will ask you about: cough, fever, sore throat, trouble breathing, wheezing, weight loss, coughing up blood, neck or chest pain, trouble swallowing, thickening of hair, cold intolerance. Your doctor will want to know if you or anyone in your family has had any of these conditions: any chronic disease, alcoholism.

V Preface The present second edition of the Color Atlas of Pharmacology goes to print six years after the first edition. Numerous revisions were needed, highlighting the dramatic continuing progress in the drug sciences. In particular, it appeared necessary to in- clude novel therapeutic principles, such as the inhibitors of platelet aggregation from the group of integrin GPIIB/IIIA antagonists, the inhibitors of viral protease, or the non-nucleoside inhibitors of reverse transcriptase. In each instance, the primary emphasis was placed on essential sites of action and basic pharmacological princi- ples. Details and individual drug properties were deliberately omitted in the interest of making drug action more transparent and affording an overview of the pharmaco- logical basis of drug therapy. The authors wish to reiterate that the Color Atlas of Pharmacology cannot replace a textbook of pharmacology, nor does it aim to do so. Rather, this little book is desi- gned to arouse the curiosity of the pharmacological novice; to help students of me- dicine and pharmacy gain an overview of the discipline and to review certain bits of information in a concise format; and, finally, to enable the experienced therapist to recall certain factual data, with perhaps some occasional amusement. Our cordial thanks go to the many readers of the multilingual editions of the Color Atlas for their suggestions.

If the cornea does not have the proper shape, the eye is unable to properly focus an image. Description Light rays entering a normal eye come to a point of Astigmatism corrected by lens focus on the retina through a transparent, dome-shaped layer called the cornea. In astigmatism there is unequal Astigmatism can be treated by the use of cylindrical lenses. Usually the degree of astigmatism re- used to determine the presence of astigmatism.

Contact lenses that are used to correct OTHER astigmatism are called toric lenses. In radial keratotomy (RK) for astigmatism, cuts are made into the cornea with a dia- mond blade instrument. In photorefractive keratectomy (PRK), a laser is used to improve the shape of the cornea by removing micro-thin slices. Laser assisted in situ ker- atomileusis (LASIK) is the most recently developed type Aston-Patterning of refractive surgery.
