Topical minoxidil (Rogaine, and others), which is available over the counter, has been used for treatment of hair loss in men and women for more than 30 years. Recently published trials suggest that off-label use of a low dose of oral minoxidil may also be effective.

Rapid exposure to altitudes more than 8,000 feet above sea level can cause serious medical problems. Since the last Medical Letter article on this subject (Vol. 30, page 89, 1988), some new information on prevention and treatment of these disorders has been reported.

In recent years, selective destruction of cardiac tissue by radiofrequency energy has become a routine procedure for treatment of some types of cardiac arrhythmias, particularly supraventricular tachycardias (MM Scheinman, Pacing Clin Electrophysiol, 18:1474, 1995).

Insulin Glargine (Lantus) is a new long-acting human insulin analog approved by the FDA for treatment of both type 1 and type 2 diabetes. Synthesized by recombinant DNA technology, it differs from human insulin at position 21 in the A-chain where asparagine is replaced by glycine and at the C-terminus of the B-chain where two arginines are added.

A vaccine to prevent both Hepatitis A and Hepatitis B (Twinrix), previously licensed in Canada and Europe, is now available in the US for adults.

Darbepoetin alfa (Aranesp) has been approved by the FDA for treatment of anemia caused by chronic renal disease and will probably also be approved for use in patients with cancer..

The first commercially available virucidal tissue, KLEENEX Anti-Viral Tissue (Kimberly-Clark), was recently introduced and is being heavily promoted to the general public. Patients may ask healthcare providers about the usefulness of these products. Theoretically, virucidal tissues could interrupt transmission of viral infections by blocking hand contamination and/or small particle aerosols from nose-blowing, sneezing and coughing.

Currently available techniques for colorectal cancer screening include fecal occult-blood testing, flexible sigmoidoscopy, double contrast barium enema (DCBE) and traditional optical colonoscopy. Optical colonoscopy requires bowel cleansing and sedation, and involves some risk, but is generally accepted as the best available method for detection of lesions and offers the advantage that polyps can be removed when they are identified. A less invasive screening tool, computed tomography (CT) colonography, also known as virtual colonoscopy (VC), offers an additional option.

The FDA has approved ceftaroline fosamil (Teflaro – Forest), an intravenous (IV) cephalosporin, for treatment of acute bacterial skin and skin structure infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA), and for treatment of community-acquired bacterial pneumonia in adults. It is the first beta-lactam antibiotic approved for treatment of MRSA.
