Congestive Heart Failure Therapy:ABSTRACT: Recent studies, although suggestive, do not yet support the routine use of angiotensin II receptor blockers in combination with angiotensin-converting enzyme (ACE) inhibitors in patients with congestive heart failure (CHF). For CHF patients in normal sinus rhythm, consider digoxin when a regimen of diuretics, ACE inhibitors, and β-blockers at optimal dosages does not relieve symptoms completely. Anticoagulation may be warranted in CHF patients with atrial fibrillation, previous embolic events, severely reduced systolic performance, or potential chamber clots. β-Blockers are indicated for patients with mild to severe CHF, unless there is a specific contraindication, and therapy should be initiated once euvolemia has been achieved. Avoid NSAIDs and cyclooxygenase-2 inhibitors in patients with CHF because the prostaglandin-blocking properties of these agents may promote fluid retention.

The keys to quickly identifying anaphylaxisAbstract: The classic presentation of anaphylaxis includes urticaria, angioedema, dyspnea, and systemic hypoperfusion. However, anaphylaxis may be more difficult to recognize if syncope, bronchospasm, or cardiovascular collapse is the predominant feature. Essential components of the history include previous allergic reactions, medication use, recently ingested foods, and exposure to latex. Although angioedema is often obvious, it also can be subtle and may require asking patients about changes they have observed. Other findings include tachypnea; wheezing; inspiratory stridor; conjunctival injection; rhinorrhea; and hoarseness, which may suggest laryngeal edema. Oxygen with ventilatory support, epinephrine, and crystalloid volume resuscitation are the mainstays of therapy for anaphylactic shock. Additional therapy often includes H1 antagonists, H2 antagonists, and corticosteroids. (J Respir Dis. 2005;26(7):308-316)

Tinea Corporis: An OverviewDermatophyte infections have a predilection for certain anatomic sites, such as the feet, groin, and scalp. Tinea corporis refers to involvement of the trunk and extremities. The condition arises either from direct exposure to an infected source or by extension from an adjacent affected site. Itch is a common symptom, but the intensity of the pruritus can vary from patient to patient.

PSA Recurrence of Prostate Cancer:ABSTRACT: Prostate-specific antigen (PSA) recurrence is the most common form of advanced prostate cancer. Salvage therapies may be effective even among some high-risk men, although long-term cancer control data are limited. The natural history of PSA recurrence is long but variable. The postrecurrence PSA doubling time can identify men at high risk for progression and death. Early hormonal therapy, possibly via combined androgen blockade, may reduce the risk of progression and improve cancer-specific survival among men with high-risk recurrence. Men with low-risk recurrences likely receive minimal benefit from aggressive early hormonal therapy and may actually be harmed.

Biologics Are Changing the Face of Psoriasis TreatmentAs dermatologists' use of biologic drugs for psoriasis grows, MCOs must take an increasingly active role in managing the near-term utilization of these high-cost agents while also taking into account that some of the "payback" for these drugs comes in the form of long-term costs avoided. Meanwhile, physicians, insurers, and employers continue to wrestle with issues such as step-down dosing; step therapy; patient-administration versus physician-administration; and whether biologic drugs should be covered under a plan's pharmacy benefit, medical benefit, or some combination. (Drug Benefit Trends. 2008;20:143-147).

Pneumomediastinum After Emergent IntubationA 33-year-old woman with a history of severe asthma requiring multiple intubations was brought to the emergency department. She had completed a 14-day course of prednisone 3 days earlier. Since then, she had had increasing dyspnea that acutely worsened after she used her albuterol nebulizer that morning. Her other asthma medications were theophylline and fluticasone. Her history included one episode of bilateral pneumothoraces secondary to barotrauma, which required chest tube insertion.

Allergic Rhinitis: Update on DiagnosisAllergic rhinitis is highly prevalent; about 20% of adults in the United States and 25% of children worldwide are affected. It is a major societal expense, with direct costs, attributable to physician visits and medications, of up to $5 billion per year, and indirect costs, mainly stemming from lost productivity, of up to $9.7 billion per year. In the United States, allergic rhinitis results in 3.5 million lost workdays and 2 million lost schooldays each year.

Since then, she had gained 5 to 10 lb, despite dieting. The patient reported a 22-pack-year history of smoking but no alcohol use. She was taking over-the-counter painkillers and allergy medications. Her family history was notable for a brother who died of laryngeal cancer.

Today's approach to the treatment of heparin-induced thrombocytopeniaAbstract: Failure to recognize heparin-induced thrombocytopenia (HIT) can lead to devastating thrombotic events, including pulmonary embolism and stroke. In most cases, the problem develops within 5 to 14 days after a first-time exposure to heparin. HIT can occur with either unfractionated heparin or low molecular weight heparin (LMWH), but the incidence is much lower with LMWH. When HIT is suspected clinically, a functional assay and immunoassay should be performed. However, treatment should not be delayed while waiting for laboratory confirmation. All forms of heparin should be eliminated, and treatment with an alternative anticoagulant should be initiated to prevent new thromboembolic events. Argatroban and lepirudin are the direct thrombin inhibitors that have been approved for the treatment of HIT. Because of the risk of warfarin-induced venous limb gangrene or skin necrosis, warfarin should be avoided in patients with acute HIT until their platelet counts have recovered and they are improving clinically.

Psoriasis: Therapeutic OptionsTopical corticosteroids remain the mainstay of treatment, especially in patients with erythematous, acutely inflamed psoriatic plaques. The topical immunomodulators tacrolimus and pimecrolimus are used to treat psoriasis, although neither has FDA approval for this indication. Unlike corticosteroids, immunomodulators do not cause skin atrophy, irreversible striae, acne, or tachyphylaxis. Newer topical vehicles of delivery (eg, foam clobetasol propionate) and newer drug combinations (eg, once-daily calcipotriene/betamethasone dipropionate ointment) may improve efficacy and reduce side effects. Reserve systemic therapy for patients with moderate to severe psoriasis. Until more long-term safety data become available, be cautious about prescribing biologic agents for patients at risk for infection (particularly tuberculosis) and malignancy.

Life-Threatening Heart Failure Associated With ItraconazoleLife-threatening heart failure associated with itraconazoleantifungal therapy developed in a patient with disseminatedCoccidioides immitis infection. This was documented bycardiac studies that demonstrated a deterioration of cardiacfunction during therapy and an improvement after itraconazoletherapy was discontinued. Heart failure associatedwith itraconazole can be missed by those unfamiliar with thiscomplication. In any patient with a fungal infection who isbeing treated with itraconazole, this serious complication canoccur; however, it can be reversible with discontinuation ofthe drug.

Emerging Treatments for Rheumatoid Arthritis:ABSTRACT: Early treatment with disease-modifying anti-rheumatic drugs (DMARDs)--alone or in combination-- can prevent joint damage and minimize disability. Until recently, the DMARDs used predominantly in patients with rheumatoid arthritis had been methotrexate, sulfasalazine, and hydoxychloroquine. Older DMARDs such as gold, d-penicillamine, and azathioprine have fallen out of favor because of their long- term toxicities or modest benefit. Six newer DMARDs--leflunomide, etanercept, infliximab, adalimumab, rituximab, and anakinra--have greatly expanded the current treatment options.
