Practical considerations in the pharmacologic treatment of idiopathic pulmonary fibrosis
Purpose of review: Idiopathic pulmonary fibrosis (IPF) is a progressive and deadly disease. The US Food and Drug Administration recently approved two medications for the treatment of IPF – pirfenidone and nintedanib. Given the limited clinical experience with these agents, a number of questions remain regarding their use. Recent findings: Both pirfenidone and nintedanib were demonstrated to reduce the rate of decline in forced vital capacity in independent large, double-blind, randomized controlled clinical trials. The successful implementation of both agents in clinical practice is dependent on many factors, including w...

How I treat adults with relapsed or refractory Philadelphia chromosome-negative acute lymphoblastic leukemia
The long-term prognosis of adult patients with relapsed Philadelphia chromosome–negative acute lymphoblastic lymphoma (ALL) is poor. Allogeneic stem cell transplant in second remission is the only curative approach and is the goal when feasible. There is no standard chemotherapy regimen for relapsed disease, although a few agents are approved for use in this setting. The bispecific CD19-directed CD3 T-cell engager, blinatumomab, has recently been granted accelerated approval by the US Food and Drug Administration for relapsed or refractory disease of B-cell lineage. For patients with relapsed T-cell ALL, nelarabine i...

Successful hemostasis and reversal of highly elevated PT/INR after dabigatran etexilate use in a patient with acute kidney injury
Dabigatran etexilate is a novel oral anticoagulant (NOAC) indicated for anticoagulation in the management of atrial fibrillation and venous thromboembolism. Prior to its approval by the United States Food and Drug administration, warfarin, a vitamin K antagonist, was one of few oral anticoagulant options. The burden of therapeutic drug monitoring, dietary restrictions, and various drug interactions associated with warfarin have countered its extensive history of efficacy. Although dabigatran etexilate may alleviate some concerns encountered with warfarin therapy, there remains a paucity of evidence surrounding emergent rev...

Next-generation sequencing to guide cancer therapy
Abstract As a result of multiple technological and practical advances, high-throughput sequencing, known more commonly as “next-generation” sequencing (NGS), can now be incorporated into standard clinical practice. Whereas early protocols relied on samples that were harvested outside of typical clinical pathology workflows, standard formalin-fixed, paraffin-embedded specimens can more regularly be used as starting materials for NGS. Furthermore, protocols for the analysis and interpretation of NGS data, as well as knowledge bases, are being amassed, allowing clinicians to act more easily on genomic informatio...

A systematic review of the use of expandable cages in the cervical spine
The objective of this study was to perform a systematic review on the use of expandable cages in the treatment of cervical spine pathology with a focus on fusion rates, deformity correction, complications, and indications. A comprehensive Medline search was performed, and 24 applicable articles were identified and included in this review. The advantages of expandable cages include greater ease of implantation with less risk of damage to the end plate, less intraoperative manipulation of the device, and potentially greater control over lordosis. They may be particularly advantageous in cases with poor bone quality, such as ...

Permanent skin discoloration possible with Daytrana patch
The Food and Drug Administration has warned that the Daytrana patch (methylphenidate transdermal system) may cause permanent skin color changes. The Daytrana patch, for attention‐deficit hyperactivity disorder, now has a new warning on the label to describe chemical leukoderma. This is a skin condition that causes the skin to lose color due to repeated exposure to specific chemical compounds. The condition is not physically harmful, but it is disfiguring. The areas of skin color loss described with the Daytrana patch ranged up to 8 inches in diameter. This condition is not thought to be reversible, which may cause emotio...

Improving Manufacturer Reporting of Adverse Events to the FDA
Our awareness of the potential adverse effects (AEs) of newly approved drugs and devices is limited. Premarket trials are often small and of limited duration, and the patients in clinical trials are healthier than unselected patients in routine clinical practice. Thus, the public and physicians rely on the US Food and Drug Administration (FDA) Adverse Event Reporting System to inform us of unknown or unsuspected risks associated with use of drugs and devices.

The Pharmacology and Clinical Use of the Antidepressants Vilazodone, Levomilnacipran, and Vortioxetine for Depression in the Elderly
This article will examine the potential role in the elderly of the three latest antidepressants approved by the US Food and Drug Administration: vilazodone (January 2011), levomilnacipran (July 2013), and vortioxetine (September 2013). Thus far, vortioxetine was shown to be efficacious and tolerable in the elderly. Sub-group analyses involving vilazodone and levomilnacipran appear to show a similar efficacy in older compared with younger adults, although these are limited by small sample sizes. Issues related to pharmacodynamics, safety, tolerability, and the unique features associated with these drugs are further discusse...

Synthetic ACTH is not superior to prednisolone for infantile spasms – Randomized clinical trials and tribulations
There are only three therapies with greater than Class IV evidence to support their use for the treatment of infantile spasms – adrencorticotropic hormone (ACTH), vigabatrin and oral corticosteroids.1 In the United States, only natural ACTH and vigabatrin are approved by the Food and Drug Administration (FDA) for infantile spasms. However, for decades oral corticosteroids have been used ‘off label’ for the treatment of infantile spasms. In contrast to ACTH and vigabatrin, oral corticosteroids are far less expensive (less than $40 for a one month course), easy to administer, and readily available in most parts of the ...

However, it may not be until after approval, when the medication is used by as many as hundreds of thousands of patients, that rare but serious adverse events appear or there is sufficient statistical power to determine whether the drug increases rates of more common potential adverse outcomes, such as cardiovascu...

Reorienting the immune system in the treatment of cancer by using anti-PD-1 and anti-PD-L1 antibodies.
Abstract Physiologically, the programmed death 1 (PD-1) pathway is involved in limiting the killing of bystander cells during an infection and controlling autoimmunity. However, cancers exploit this system to avoid immune killing, and PD-1 ligand 1 and 2 (PD-L1 and PD-L2) expression on tumor cells, as well as PD-1 expression on tumor-infiltrating lymphocytes, have shown to be negative prognostic factors. Promising clinical results have been obtained by PD-1 pathway blockade in a range of cancers while still maintaining a manageable toxicity profile, and two anti-PD-1 antibodies are now approved by the US Food and D...

Citrobacter braakii: A Major Cause of False‐Positive Results on MacConkey and Levine's Eosin Methylene Blue Selective Agars Used for the Isolation of Escherichia Coli from Fresh Vegetable Samples
In this study, we investigated the efficiency of conventional E. coli selective medium, MacConkey (MAC) agar, for the screening of fresh vegetable samples and evaluated the discrimination ability of Levine's eosin methylene blue (L‐EMB) agar for E. coli‐like colonies obtained from MAC agar. A total of 120 samples of lettuces (n = 60) and radish sprouts (n = 60) were analyzed. Among 17 (14.2%) MAC agar plates containing putative E. coli colonies, only one plate was confirmed E. coli‐positive (positive predictive value = 5.9%). All 16 false‐positive isolates were identified as Citrobacter braakii ...

Glycoprotein IIb/IIIa inhibitors: The resurgence of tirofiban.
Abstract Glycoprotein (GP) IIb/IIIa inhibitors block platelet aggregation, reducing thrombotic events in acute coronary syndrome. They are most often utilized in patients who likely have an intracoronary thrombus. Tirofiban, eptifibatide, and abciximab are the three GP IIb/IIIa inhibitors approved for use in the United States. Each agent has unique pharmacological properties. They all have a rapid onset and are most often utilized in conjunction with heparin. Tirofiban, in particular, fell out of favor due to inferior dosing with its original Food and Drug Administration (FDA) approved indication, but has re-emerge...
