Orthopnea is dyspnea that occurs when the patient is lying down and improves when the patient sits up. The episode usually subsides but may recur at about the same time on subsequent nights. Edema refers to the accumulation of excessive fluid in the interstitial tissue spaces and appears as swelling. Questions about edema are typically included in the cardiac history, but edema has many other causes, both local and general. Focus your questions on the location, timing, and setting of the swelling, and on associated symptoms. Dependent edema appears in the lowest body parts (the feet and lower legs) when sitting or the sacrum when bedridden. Causes may be cardiac (congestive heart failure), nutritional (hypoalbuminemia), or positional. Edema occurs in renal and liver disease: periorbital puffiness, tight rings in nephrotic syndrome; enlarged waistline from ascites and liver failure. Education and counseling will guide your patients to maintain optimal levels of cholesterol, weight, and exercise. First, obtain a fasting lipid profile in all adults aged 20 years or older once every 5 years. Risk equivalents include diabetes; other forms of atherosclerotic disease-peripheral vascular disease, abdominal aortic aneurysm, and symptomatic carotid artery disease; and 2 or more risk factors, raising the 10-year risk of coronary heart disease to more than 20%. The report includes tables for assessing 10-year risk for men and for women if multiple risk factors are present.

Together with the patient, review the basic principles for all healthy diets: high intake of fruits, vegetables, and grains; use of low-fat dairy products and lean meats, substituting chicken and fish when possible; and minimal intake of processed food and added salt and sugar, both when cooking and at the table. Eggs with yolks, the most concentrated source of cholesterol, should be limited to two to four per week. Sources of fiber include whole-grain breads; pasta; and oat, wheat, corn, or multigrain cereals. For counseling about weight, apply the principles for assessing body mass index enumerated in Chapter 3 (pp. To maintain a desirable body weight, energy expended must balance calories consumed. Metabolism of food fat, which contains 9 calories of potential energy per gram, uses up fewer calories than metabolism of foods high in carbohydrate or protein, which provide 4 calories of energy per gram. Patients with high fat intake are more likely to accumulate body fat than patients with increased protein and carbohydrate intake (and patients with low-fat diets may lose weight more quickly). Set realistic goals that will help the patient maintain healthy eating patterns for life. To reduce risk for coronary artery disease, counsel patients to pursue aerobic exercise, or exercise that increases muscle oxygen uptake. Since the cardiovascular benefits of exercise are long term, to help motivate patients be sure to emphasize that the patient will look and feel better as soon as exercise begins. Before selecting an exercise regimen, do a thorough evaluation of any cardiovascular, pulmonary, or musculoskeletal conditions presenting a risk for exercise. Guiding the patient to make time to exercise as a regular activity is often more important than the type of exercise chosen. For cardiovascular benefit, patients should exerise for 20 to 60 minutes at least 3 times a week. For patients losing weight, paradoxically, the metabolic rate may drop when caloric intake declines, known as the starvation response. Recommended blood pressure screening for healthy adults is generally once every 2 years.

As the breasts enlarge throughout pregnancy, women may experience upper backache from their increased weight. There is also increased blood flow throughout the breasts, increasing pressure on the tissue. If a woman experiences nausea and vomiting, she may not be eating normally in early pregnancy (see nausea above). Rapid uterine growth early in second trimester causes tension and stretching of round ligaments, causing spasm with sudden movement or change of position. There is increased blood volume and increased filtration rate in the kidneys with increased urine production. Due to less space for the bladder from pressure from the growing uterus (first trimester) or from the descent of the fetal head (third trimester), the woman needs to empty her bladder more frequently. Rapid change in energy requirements; hormonal changes (progesterone has a sedative effect); in third trimester, weight gain, changes in mechanics of movement, and sleep disturbances contribute. There is increased venous pressure in the legs, obstruction of lymphatic flow, and reduced plasma colloid osmotic pressure. Relaxation of the lower esophageal sphincter allows stomach contents to back up into the lower esophagus. Hormonally induced relaxation of joints and ligaments and the minor lordosis required to balance the growing uterus sometimes result in a lower backache. Increased secretions from the cervix and the vaginal epithelium, due to the hormones and vasocongestion of pregnancy, result in an asymptomatic milky white vaginal discharge. Early in pregnancy, the corpus luteum, the ovarian follicle that has discharged its ovum, may be sufficiently prominent to be felt on the affected ovary as a small nodule, but it disappears by midpregnancy. It is important to examine the fallopian tubes to rule out a tubal pregnancy (see p. The woman will usually have many questions for you about her pregnancy and seek understanding of her symptoms. Ask about symptoms of pregnancy such as breast tenderness, nausea or vomiting, urinary frequency, change in bowel habits, and fatigue (see table on p. Although best identified and addressed before conception, are there any sources of high-level stress? If she works, has there been any exposure to teratogenic drugs or toxic substances? Has she had any major complications of pregnancy or problems with labor or delivery? Ask also about her past medical history, especially any chronic diseases like hypertension, diabetes, or cardiac conditions. In addition, the clinician should get information needed for calculating the expected weeks of gestation by dates. Menstrual age is used most frequently to express the weeks of gestation calculated by dates. This information is often one of the first questions the pregnant woman asks when seeking confirmation of pregnancy. You can then compare the expected size by dates with what you actually palpate during the bimanual examination, or abdominally, if pregnancy is beyond 14 weeks of gestation. Uterine size is measured by the palpable size of the uterus if still within the pelvic cavity, or by the height of the fundus if above the symphysis pubis. Accurately dating the pregnancy is best done early, and contributes to good decision-making later in pregnancy if the fetus is not growing well, if preterm labor is suspected, or if the pregnancy goes beyond 42 weeks of gestation.
They are used as bandages and substrates for topical medication in the treatment of anterior disorders bacteria define effective 0.5 mg colcitrat, such as erosion or ulcer treatment for dogs chocolate colcitrat 0.5 mg fast delivery. They produce good cosmetic results bacteria mod 179 purchase 0.5mg colcitrat with amex, reduce glare antibiotics with alcohol colcitrat 0.5 mg, and can correct a refractive error where indicated. Bifocal contact lenses: these lenses were developed to allow the use of contact lenses in presbyopic patients. This near-field portion is always located at the bottom of the lens because the lens is heavier there. When the patient gazes downward to read, the immobile lower eyelid pushes this near-field portion superiorly where it aligns with the pupil and becomes optically effective. Another possibility is diffraction (bending of light rays as opposed to refraction) through concentric rings on the posterior surface of the contact lens. This produces two images, a distant refractive image and a near-field diffractive image. It is also possible to correct one eye for distance vision and the fellow eye for near vision (monocular vision). Disadvantages of Contact Lenses Contact lenses exert mechanical and metabolic influences on the cornea. This is more difficult, time-consuming, and more expensive than eyeglass care and is particular important with soft lenses. Metabolic influences on the cornea: the macromolecular mesh of material absorbs proteins, protein breakdown products, low-molecular-weight substances such as medications and disinfectants, and bacteria and fungi. Serious complications can occur where daily care of the contact lenses is inadequate. With their threshold oxygen permeability, soft contact lenses interfere with corneal metabolism. Contact lenses are less suitable for patients with symptoms of keratoconjunctivitis sicca. Contact Lens Complications Complications have been observed primarily in patients wearing soft contact lenses. These include: Infectious keratitis (corneal infiltrations and ulcers) caused by bacteria, fungi, and protozoans. Giant papillary conjunctivitis: this is an allergic reaction of the palpebral conjunctiva of the upper eyelid to denatured proteins. Corneal vascularization may be interpreted as the result of insufficient supply of oxygen to the cornea. Severe chronic conjunctivitis: this usually makes it impossible to continue wearing contact lenses. When prescribing eyeglasses, the ophthalmologist specifies the strength and the position of the base of the prism. Prism lenses are used to correct heterophoria (latent strabismus) and ocular muscle palsies, and in preparation for surgery to correct strabismus. A 1 diopter prism deflects a ray of light 1 cm at a distance of 1 m from the base of the prism. However, magnification is always associated with a reduction in the size of the visual field. As a result, these vision aids require patience, adaptation, motivation, and dexterity. Increased near-field corrections: the stronger the near-field correction, the shorter the reading distance. Magnification (V) is a function of the refractive power of the near-field correction (D) and is determined by the equation V = D/4. Example: Eyeglasses with a 10 diopter near-field correction magnify the image two and one-half powers. Magnifying glasses are available in various strengths, with or without illumination. These aberrations are not material flaws, rather they are due to the laws of physics.
