Harvesting of autogenous bone, most commonly from the iliac crest, for use as the interbody graft in spinal fusion procedures has been standard practice, but is associated with a high rate of morbidity, including graft site pain, infection, fracture, bleeding and damage to the femoral nerve. Use of recombinant human bone morphogenetic protein (rhBMP-2; Infuse Bone Graft - Medtronic) was first approved by the FDA in 2002 for single-level anterior lumbar spinal fusion in adults with degenerative disc disease who had not responded to at least 6 months of nonoperative treatment. Now it has also...

Cytomegalovirus immune globulin (CMVIG) for intravenous administration is now available in the USA on an investigational basis (FE Young and SL Nightingale, JAMA, 260:224, July 8, 1988) for prevention of cytomegalovirus (CMV) infection in CMV-seronegative renal transplant recipients who receive a kidney from a seropositive donor. CMVIG contains IgG antibodies from a pool of healthy donors with high titers of antibodies against CMV. The drug can be obtained from the Massachusetts Department of Public Health Biologic Laboratories (617-522-3700, extension 264) or the American Red Cross...

A condom for women (Reality - Wisconsin Pharmacal) to prevent pregnancy and sexually transmitted diseases, including AIDS, has been approved for marketing by the US Food and Drug Administration (FDA).

Betaine (Cystadane - Orphan Medical), an orphan drug, has recently been marketed for treatment of homocystinuria, a genetic disorder. Patients with homocystinuria frequently have premature atherosclerosis and thromboembolism, and may also have lens dislocations, skeletal abnormalities and mental retardation (SH Mudd et al in CR Scriver et al, eds, The Metabolic and Molecular Bases of Inherited Disease, 7th ed, New York:McGraw Hill, 1995, page 1279).

The US Public Health Service Advisory Committee on Immunization Practices has recently published new recommendations for prevention and control of meningococcal disease in college students.

The FDA has licensed the adjuvanted, recombinant varicella zoster virus (VZV) vaccine Shingrix (GSK) for prevention of herpes zoster (shingles) in adults of any age who are or will be at elevated risk because of disease- or therapy-induced immunodeficiency or immunosuppression. Shingrix has been licensed for herpes zoster prevention in adults ≥50 years old since 2017.1 It is the only VZV vaccine currently available in the US; Zostavax, a live-attenuated VZV vaccine, was withdrawn from the market in 2020.

Six vaccines are recommended for routine use in adults living in the USA (Guide for Adult Immunization, 2nd ed, Philadelphia:American College of Physicians, 1990). Immunization recommendations for travel outside the USA were published in The Medical Letter, volume 32, page 33, April 6, 1990.
