PHILADELPHIA -- An aggressive approach to hypertension management in the U.S. has paid off in better blood pressure control than achieved in Europe, according to U.S. investigators.

CHICAGO -- Inhibitors of the renin-angiotensin system trumped calcium-channel-blockers, beta-blockers, and diuretics in preventing diabetes, according to a network meta-analysis of hypertension trials.

BALTIMORE -- The most vulnerable age for girls to initially put on too much weight is from nine to 12, and that may lead to high blood pressure and other cardiovascular risk factors, according to investigators here.

On a warm August day, a 79-year-old man is hospitalized because of progressive lethargy over the past week. Previously, he was alert and able to converse. He has no chest pain, dyspnea, or cough. His history includes hypertension of unknown duration, chronic obstructive pulmonary disease, and a recent hospitalization for pneumonia.

For several days, a 38-year-old man has had an increasingly painful swelling behind the right knee. He runs several times a week. He has hypertension but no history of trauma or periods of inactivity, and no chest discomfort or shortness of breath. He drinks alcohol occasionally but does not use tobacco or illegal drugs.

To facilitate the assessment of jugular venous pressure, shine a beam of light tangentially across the skin overlying the jugular vein while the patient's neck muscles are relaxed.

Q:Is periodic laboratory monitoring recommended for patients withosteoarthritis who are receiving long-term cyclooxygenase-2 (COX-2)inhibitor therapy and who have no GI or renal symptoms? Similarly,is laboratory monitoring recommended for women who take a selectiveCOX-2 inhibitor to alleviate menstrual cramps (eg, rofecoxib, 50 mg/d,3 to 5 days per month)?--Sarita Salzberg, MDColumbus, Ohio

A pruritic rash under the left breast has bothered a 67-year-old woman forthe past month. She takes an antihypertensive and is otherwise healthy.

For 3 months, a 66-year-old retired man has had increasingweakness of the lower legs with stiffness,tingling, and numbness; worsening ataxia; anergia; andexertional dyspnea of insidious onset. He has lost 8 lb,and his appetite is poor. He denies fever, cough, chest orabdominal pain, paroxysmal nocturnal dyspnea, orthopnea,ankle swelling, bleeding disorders, hematemesis,melena, headache, vision problems, sciatica, joint pain,bladder or bowel dysfunction, and GI symptoms. He hasnocturia attributable to benign prostatic hypertrophy.

A 78-year-old widower with hypertension, type 2 diabetes, and hyperlipidemiais referred for a comprehensive geriatric assessment.His daughter is concerned about her father’s decline following her mother’s death a year ago.His memory seems to be deteriorating. His desk is cluttered with bills, but he refuses to lethis daughter help him or even look at his checkbook.

For the past week, a 16-year-old boy has had a progressively worsening dry, irritating cough; dyspnea on exertion; and intermittent fever and chills. During the past 24 hours, he has had no appetite and has vomited greenish material 3 or 4 times.

Q:How can I accurately determine when a patient’s hypertension isresistant to treatment-and what is the best approach to theevaluation?

Q:Under what circumstances is 24-hour ambulatoryblood pressure monitoring (ABPM) appropriate?

Q:Do evidence-based data support combination therapy with anangiotensin-converting enzyme (ACE) inhibitor and an angiotensin IIreceptor blocker (ARB)?

An 83-year-old woman is hospitalized for treatment of deep venous thrombosisin her left leg. She underwent left hip replacement surgery 2 months earlier.At that time, mild anemia (hemoglobin level, 10 g/dL) was noted, and iron therapywas initiated. An iron panel obtained shortly after the hip surgery revealeda serum iron level of 80 μg/dL, a transferrin level of 360 mg/dL, and a ferritinlevel of 50 ng/mL.

Issues of when and whom to screen for various diseases and conditions have longbeen sources of controversy. The amount of information about screening tests canbe overwhelming, and the costs of the latest preventive technology can be daunting.To provide an evidence base for decision making in one source for busy clinicians,Dr Snow has compiled key previously published reviews of the data behind the latestUS Preventive Services Task Force (USPSTF) screening recommendations fortype 2 diabetes, postmenopausal osteoporosis, breast cancer, colorectal cancer, andprostate cancer. Also included are reviews of the evidence concerning chemoprophylaxisof cardiovascular disease (with aspirin and with hormone replacementtherapy) as well as reviews of the latest data on screening for hypertension and depression,which were specially commissioned for this volume. The reviews containguidelines on which patients to screen and address the issue of screening frequency-in terms of both optimum patient care and maximum cost-effectiveness. Inaddition, a list of key points that summarize important “take-home” messages precedeeach review. The book also contains a valuable introduction (“How to ThinkAbout Screening” by David M. Eddy, MD, PhD) and a concise guide to 25 preventiveservices.

My patient-an 84-year-old woman with hypertension-presented with itchingand blistering of 3 days’ duration on her right foot (Figure).

Q:Should hypertensive patients be discouraged from participating inmoderate to vigorous exercise?A:On the contrary, most patients with sustained hypertension should bestrongly encouraged to exercise regularly at moderate to vigorous levels.Randomized controlled clinical trials have demonstrated that increasedphysical activity can lower blood pressure (BP) and delay or prevent the developmentof hypertension and thus the need for antihypertensive medication.1In addition, physical activity can help reduce cardiovascular risk factors by improvinglipid profiles and reducing weight and blood glucose levels. In elderlypersons, exercise is associated with improvements in osteoporosis, depression,and physical functioning, as well as an enhanced sense of well-being.

Cataracts areone of themost importantcauses ofreversibleblindness in elderly persons.1 A recent report thatpredicts a surge in cataractincidence has heightenedawareness of the importanceof proper timing andtechniques for cataract extraction.The study, authoredby the Eye DiseasesPrevalence ResearchGroup, estimated that thenumber of Americans withcataracts will increase byapproximately 50% in thenext 20 years as the populationages.2 Cataracts werethe leading cause of low vision(less than 20/40 bestcorrected visual acuity inthe better-seeing eye)among whites, blacks, andHispanics.

The FDA has approved injectable Acetadote (acetylcysteine)from Cumberland Pharmaceuticals Incto prevent or lessen liver damage resulting from an overdoseof acetaminophen. According to the FDA, unintentionalacetaminophen overdose is responsible for 100deaths and 56,000 emergency department visits per year.

Is treatment recommended for high-normalblood pressure (BP)-say, 135/88 mm Hg-ina postmenopausal woman?

We chose to present this case to readersbecause the patient’s neurologicexamination was normal and her presentationthus appeared benign.

I have read that mental confusion and paranoia may be potential side effects ofcertain angiotensin-converting enzyme (ACE) inhibitors.
