Cough and cold medications: Why don't they go away?
At some level, most of us realize that the bulk of “cough and cold medications” don't really work and may be harmful to children. About six years ago, the US Food and Drug Administration and the pharmaceutical industry undertook some initiatives to limit the use of such preparations in young children, those most vulnerable to adverse effects.

Custom-made versus off-the-shelf multibranched endografts for endovascular repair of thoracoabdominal aortic aneurysms
In April 2012, the Food and Drug Administration approved a fenestrated endoprosthesis to treat the visceral aorta. Therefore, the existing Category III CPT codes that were used for fenestrated endovascular repair (FEVAR) of the visceral aorta were replaced with Category I CPT codes in the 2014 manual. One set of codes were created for treatment of the visceral aorta alone and a parallel set was created to report concomitant repair of the visceral aorta and the infrarenal aorta. Simultaneous to this, the four Category III CPT codes were deleted. (Source: Journal of Vascular Surgery)

New Therapies for Primary Biliary Cirrhosis
Abstract Primary biliary cirrhosis (PBC) is a rare inflammatory liver disease for which ursodeoxycholic acid (UDCA) is the only therapy approved by the U.S. Food and Drug Administration. Patients with a biochemical response to UDCA therapy have a similar survival rate compared to the general population. However, up to 40 % of PBC patients do not achieve a complete response to UDCA, have an increased risk of liver-related death and liver transplantation, and represent a persistent medical need for new therapies. Several novel drugs have recently been studied and show potential efficacy in PBC. Obeticholic acid, a ...

Drug delivery to the ischemic brain.
Abstract Cerebral ischemia occurs when blood flow to the brain is insufficient to meet metabolic demand. This can result from cerebral artery occlusion that interrupts blood flow, limits CNS supply of oxygen and glucose, and causes an infarction/ischemic stroke. Ischemia initiates a cascade of molecular events in neurons and cerebrovascular endothelial cells including energy depletion, dissipation of ion gradients, calcium overload, excitotoxicity, oxidative stress, and accumulation of ions and fluid. Blood-brain barrier (BBB) disruption is associated with cerebral ischemia and leads to vasogenic edema, a primary c...

Questioning the association between bisphosphonates and atypical femoral fractures
Bisphosphonates are the first‐line treatment for osteoporosis. Structurally, they are stable analogues of pyrophosphate and therefore exhibit a high affinity for bone mineral. They reduce bone loss by attenuating the ability of the osteoclast to resorb bone, decreasing activation frequency, and the rate of remodeling. Large prospective randomized placebo‐control trials provide unequivocal evidence for a reduction in the incidence of fractures. Impressively, 40 years since their first use in patients, the safety profile of bisphosphonates has been equally reassuring. Questions have arisen lately as to whether bisphospho...

Late Cardiac Tamponade in Adults Secondary to Tip Position in the Right Atrium: An Urban Legend? A Systematic Review of the Literature
CENTRAL VENOUS CATHETER (CVC) placement is a very common procedure, considering that the Food and Drug Administration (FDA) has estimated that 5 to 6 million CVCs are placed annually in the United States. The FDA also receives reports that are useful in the identification of emerging problems associated with device use. More than a decade ago, one of these emerging problems was cardiac tamponade, a very rare but potentially fatal complication associated with CVC placement. Diagnosis of cardiac tamponade (CT) often is delayed, even when signs and symptoms are typical. (Source: Journal of Cardiothoracic and Vascular Anesthesia)

Purpose of review: To present an overview of HIV-associated distal symmetric polyneuropathy (HIV-DSP) and other HIV-related peripheral neuropathies in the post-highly active retroviral therapy era. Recent findings: HIV-DSP has become the most common neurologic complication of HIV largely due to the prolonged survival of HIV-positive patients with the advent of highly active retroviral therapy. HIV-DSP can be attributed to the disease itself or to secondary effects of certain HAART agents, and often the two disease entities cannot be distinguished. HIV-DSP can lead to significant morbidity and interfere with daily activitie...

Specialty Pharmaceuticals: Policy Initiatives To Improve Assessment, Pricing, Prescription, And Use [Spending On Specialty Pharmaceuticals]
This article analyzes the five principal stages through which a specialty drug must pass on its journey from the laboratory to the bedside. These include regulatory approval by the Food and Drug Administration for market access, insurance coverage, pricing and payment, physician prescription, and patient engagement. If structured appropriately, each stage improves performance and supports continued research and development. If structured inappropriately, however, each stage adds to administrative burdens, distorts clinical decision making, and weakens incentives for innovation. Cautious optimism is in order, but neither th...

Despite High Costs, Specialty Drugs May Offer Value For Money Comparable To That Of Traditional Drugs [Spending On Specialty Pharmaceuticals]
Specialty drugs are often many times more expensive than traditional drugs, which raises questions of affordability and value. We compared the value of specialty and traditional drugs approved by the Food and Drug Administration (FDA) in the period 1999–2011. To do this, we identified published estimates of additional health gains (measured in quality-adjusted life-years, or QALYs) and increased costs of drug and health care resource use that were associated with fifty-eight specialty drugs and forty-four traditional drugs, compared to preexisting care. We found that specialty drugs offered greater QALY gains (0.183 ...
