The FDA has approved the use of a responsive neurostimulator device (RNS System – NeuroPace) for adjunctive treatment of adults with partial-onset seizures that are not controlled with ≥2 antiepileptic drugs and who have frequent and disabling seizures and no more than 2 epileptogenic foci.

Human rabies continues to be rare in the USA, but animal rabies is becoming more common. An animal epizootic in the mid-Atlantic states, involving especially raccoons, has recently spread into the northeastern states.

The well-publicized recovery from paralysis of a professional football player has recently focused attention on the growing use of drugs to minimize the effects of spinal cord injury. Methylprednisolone sodium succinate (Solu-Medrol - Upjohn), commercially available in the USA for intravenous treatment of transplant rejection and various inflammatory and auto-immune disorders, and GM-1 ganglioside, commercially available in Italy (Sygen - Fidia) but not in the USA, are now widely used in patients with spinal cord injury.

Prosorba, an antibody-adsorbing column used with plasmapheresis, has been approved by the FDA for treatment of moderate-to-severe rheumatoid arthritis in patients refractory or intolerant to methotrexate and other disease-modifying anti-rheumatic drugs (DMARDs).

Doconsanol 10% cream, a long-chain saturated alcohol, has been approved by the FDA for over-the-counter treatment of herpes labialis.

Recent reports (D Kaye.Clin Infect Dis April 1, 2008;46:iii) indicate that 2 of the 3 components of this year's influenza vaccine (Med Lett Drugs Ther 2007;49:81), the influenza B and A/H3N2 antigens, do not matchup well with circulating strains. The B component is probably not protective. The A/H3N2 antigen in the vaccine probably provides some protection, particularly for high-risk patients. The third component, the A/H1N1 antigen, is protective against circulating A/H1N1 influenza viruses, but these viruses, unlike previous A/H1N1 strains, are developing some resistance to oseltamivir...

The CDC recently reported that fluoroquinoloneresistant strains of Neisseria meningitidis have been detected for the first time in the US in an area around the border of North Dakota and Minnesota (CDC. MMWR, Feb 22, 2008). These isolates were all serogroup B, for which meningococcal vaccines (Med Lett Drugs Ther 2005; 47:29) do not offer protection. Since many laboratories do not test N. meningitidis for antimicrobial susceptibility, it is possible that such resistance is more widespread. A single oral dose of ciprofloxacin (Cipro, and others) 500 mg has been used for prophylaxis after close...

The antibiotic aztreonam is now available as an inhalation solution (Cayston – Gilead) to improve respiratory symptoms in cystic fibrosis (CF) patients ≥7 years old colonized with Pseudomonas aeruginosa. It is the second inhaled antibiotic to be FDA-approved for this indication in CF patients; the aminoglycoside tobramycin (Tobi) was the first. Inhaled antibiotics offer the advantage of high airway concentrations while minimizing systemic side effects.

The FDA has approved the erythropoiesis-stimulating agent (ESA) peginesatide (Omontys – Affymax/Takeda), a synthetic peptide analog of erythropoietin, for treatment of anemia in patients with chronic kidney disease (CKD) who are on dialysis. Peginesatide is the third ESA to become available in the US.Overuse of the other two, which have broader indications, has been a concern.

The FDA has approved ibrutinib (eye broo' ti nib; Imbruvica – Janssen/Pharmacyclics), an oral kinase inhibitor, for second-line treatment of chronic lymphocytic leukemia (CLL). It is the first kinase inhibitor to be approved for CLL. Ibrutinib was approved earlier for second-line treatment of mantle cell lymphoma, a rare form of B-cell non-Hodgkins lymphoma.
