The 2013 guidelines from the American College of Cardiology and the American H eart Association recommend statin t herapy for t he following groups: 1. Patients age 40 to 75, without diagnosed cardiovascular disease or diabetes, but with a 10-years risk of cardiovascular events ≥ 7. Low-grade myalgias occur in < 10% of pat ient s, but severe myopathy is reported in 0. Less commonly, elevated liver enzymes, or even severe h epat it is, h ave been repor t ed. W h en t h ese drugs are used, routine clinical or laboratory monitoring for these effects is advis- able. H e has diet-controlled diabetes mellitus, plays tennis, exercises three to five times per week, and appears to be in good physical condit ion. Following a review of this patient’s profile, which of the following would you recommend? The recommended interval for cholesterol screening in this population of healthy adults is every 5 years.

He previously had been well but has a medical history of hypercholesterolemia and a 40-pack-year history of smoking. On examination, he appears uncomfortable and diaphoretic, with a heart rate of 116 bpm, blood pressure of 166/102 mm Hg, respiratory rate of 22 breaths per minute, and oxygen saturation of 96% on room air.

Paint “huffers” often present with residual perioral or fingertip paint from inhalation discount erythromycin 500mg free shipping antibiotic 802. Because of the increased solvent content in metallic-colored paints erythromycin 500 mg visa antibiotic eye ointment, gold and silver spray paints are particularly popular buy generic alli 60 mg on line. Initial stages of acute inhalant use are characterized by eupho- ria, excitation, exhilaration, dizziness, hallucinations, excess salivation, sneezing, flushed skin, and bizarre behavior. More concerning signs of inhalant intoxication are disorientation, double vision, nystagmus, bizarre dreams, epileptiform activity, arrhythmias, and unconsciousness. Chronic use causes difficulty coordinating movement, gait disorders, muscle tremors, and spasticity due to neurotoxic effects of inhalants, hypoxia, or both. Other toxicity includes pulmonary hypertension, restrictive lung defects or reduced diffusion capacity, hematuria, tubular acidosis, and possibly cerebral and cerebellar atrophy. Treatment is supportive and directed toward control of dysrhythmias and stabi- lization of respirations and circulation. Bath Salts “Bath salts” are newly popular drugs that act as a central nervous system stimulant by inhibiting norepinephrine-dopaminergic reuptake. Legal until early 2012, “bath salts” con- sumption and distribution was widespread and difficult to follow. Common symp- toms include euphoria, dilated pupils, loss of inhibition, involuntary muscle move- ment, tachycardia, and hypertension. Thus, early diagnosis and intervention at routine health screenings is an important component of the well-child examination. In addition, a family history of drug addiction or abuse should raise the level of concern about potential drug abuse. A significant change in school performance or other daily behaviors is noted, and frequent or serious accidents occur (atypical motor vehicular accidents). Screening and diagnostic testing in an older, competent adolescent may be carried out, with few exceptions, only with the patient’s consent. Parental permission is not sufficient for involuntary screening in these patients. Consent may be waived when the patient’s competency is questionable or when findings from the interview and physical examination strongly suggest the patient is at high risk for serious harm from substance use. Staging substance abuse provides the clinician with a means of monitoring progress and providing an objective means of conveying treatment goals (Table 49–2). Group counseling, individualized counseling, and multifamily educational intervention have been found to be effective interventions for teens with substance use disorders. Outpatient management is often the first line of treatment for teens identified as meeting Stage 4 or Stage 5 criteria.

Unlike mild deficiency buy erythromycin 500mg mastercard virus ntl, in which erythrocytes are the only blood cells affected buy erythromycin 250 mg free shipping treatment for fungal uti, severe deficiency disrupts production of all blood cells generic coumadin 2 mg without prescription. Loss of erythrocytes leads to hypoxia, cerebrovascular insufficiency, and heart failure. Loss of leukocytes encourages infection, and loss of thrombocytes promotes bleeding. After treatment with vitamin B12 plus folic acid, recovery from anemia occurs quickly. Within 1 to 2 days, megaloblasts disappear from the bone marrow; within 3 to 5 days, reticulocyte counts become elevated; by day 10, the hematocrit begins to rise; and within 14 to 21 days, the hematocrit becomes normal. Recovery from neurologic damage is slow and depends on how long the damage had been present. When deficits have been present for only 2 to 3 months, recovery is relatively fast. When deficits have been present for many months or for years, recovery is slow: Months may pass before any improvement is apparent, and complete recovery may never occur. Long-Term Treatment For patients who lack intrinsic factor or who suffer from some other permanent cause of vitamin B12 malabsorption, lifelong treatment is required. However, large daily oral doses can be just as effective, as can weekly intranasal doses. During prolonged therapy, treatment should be periodically assessed: plasma levels of vitamin B12 should be measured every 3 to 6 months, blood samples should be examined for the return of macrocytes, and blood counts should be performed. Potential Hazard of Folic Acid Treatment with folic acid can exacerbate the neurologic consequences of B12 deficiency. Recall that folic acid, by itself, can reverse the hematologic effects of B12 deficiency—but will not alleviate neurologic deficits. So, by correcting the most obvious manifestation of B12 deficiency (anemia), folic acid can mask the fact that deficiency of B12 still exists. As a result, use of folic acid can lead to undertreatment with B itself12 and can thereby permit neurologic damage to progress. Clearly, folic acid is not a substitute for vitamin B12, and vitamin B12 deficiency should never be treated with folic acid alone. Whenever folic acid is employed during treatment of vitamin B12 deficiency, extra care must be taken to ensure that B12 dosage is adequate. Folic Acid Deficiency In one respect, folic acid deficiency is identical to vitamin B12 deficiency: in both states, megaloblastic anemia is the most conspicuous pathology. However, in other important ways, folic acid deficiency and vitamin B12 deficiency are dissimilar (Table 45.

Co n s i d e r a t i o n s A 62-year-old man with hypertension and st able angina present s with a 4. The patient’s physical examination is suggestive of aneursymal disease in the femoral and popliteal arteries. Aneurysm formation is caused by conditions that cause weakening of the arterial walls, including collagen defect s, inflammatory conditions, immune responses, and atherosclerotic changes.

The process is associated wit h infilt rat ion of the arterial wall by lym- phocytes and macrophages, destruction of the elastin and collagen in the media and adventitia of the artery, and loss of smooth-muscle cells resulting in thinning of the arterial wall. A number of risk-reduction strategies has been identified to decrease aneurysm ruptures including smoking cessation, control of hypertension and hypercholesterolemia.
