Follow-up Testing Among Children With Elevated Screening Blood Lead Levels

Interview with Alex R. Kemper, MD, MPH, MS, author of Follow-up Testing Among Children With Elevated Screening Blood Lead Levels, published in the May 11 issue of JAMA, the Journal of the American Medical Association. Summary Points: 1. About half the children (six years and younger) with elevated blood lead levels did not receive follow up testing. 2. Nonwhite children, and those living in urban as well as high-risk lead settings, were less likely to receive follow up testing compared to their counterparts. 3. Follow-up testing for children with high blood lead levels is essential for managing lead poisoning and for maximizing cognitive development. 4. Interventions are needed to overcome disparities in care.

Update on the Treatment of Tuberculosis and Latent Tuberculosis Infection

Interview with Henry M. Blumberg, MD, author of Update on the Treatment of Tuberculosis and Latent Tuberculosis Infection, published in the June 8 issue of JAMA, the Journal of the American Medical Association. Summary Points: 1. Tuberculosis is a public health problem. The responsibility for prescribing an appropriate regimen and assuring that treatment is completed is assigned to the public health program or the treating physician, not the patient. 2. Directly observed therapy is recommended for all patients being treated for active TB, this will necessitate the need for greater collaboration between the treating physician and the public health department. 3. Initial therapy for newly diagnosed patients with tuberculosis consists of a 4-drug regimen including isoniazid, rifampin, pyrazinamide and ethambutol. 4. Testing for latent TB infection should be targeted at those who are at increased risk of progression to active TB. 5. Despite its limitations, the tuberculin skin test remains the most commonly used test for the diagnosis of latent TB infection; newer diagnostic tests for latent TB infection are on the horizon. 6. Active tuberculosis should be excluded before beginning treatment for latent tuberculosis infection. 7. Nine months of isoniazid is the preferred therapy for the treatment of latent TB infection.

Safety: The combined tetanus-diphtheria 5-component pertussis vaccine is safe, as the reactions are the same as the tetanus vaccine. 3. Universal: On June 30, 2005, the American Academy of Pediatrics (ASAP), America Academy of Family Physicians (AFAR), and the Advisory Committee on Immunization Practices (ACID) all recommended the universal use of the combined tetanus-diphtheria 5-component pertussis vaccine or its competitor vaccine for adolescents.

Women in the E plus P group reported higher rates of pain or stiffness (36.8%) after they stopped study medication compared to women who had been on placebo (22.2%). 4. Women who had symptoms after they stopped study medication reported using a wide range of strategies to manage symptoms and a large proportion found the strategies to be helpful.

Interview with Melanie A. Thompson, MD, and Paul A. Volberding, MD, authors of Antiretroviral Treatment of Adult HIV Infection 2012 Recommendations of the International Antiviral Society-USA Panel. Summary Points:

  • Antiretroviral treatment is recommended and should be offered to all persons with HIV, regardless of CD4 cell count.
  • Particular attention should be paid to the design of an antiretroviral regimen for persons with concurrent conditions, such as viral hepatitis, opportunistic infections, and other medical diseases, because of the potential for drug interactions.
  • Monitoring of entry into and retention in HIV care, adherence to antiretroviral therapy, and quality of care indicators are recommended and should be used to increase care engagement and quality.

Forty Years of A Piece of My Mind

Forty years ago, in 1980, Jimmy Carter was president. Pac-Man debuted. In medicine, smallpox was declared to be eradicated. Additionally, on May 9, 1980, A Piece of My Mind was inaugurated in JAMA. The first essay, “Tuna on Rye, 1984,” was written by then–senior editor Samuel Vaisrub under the pen name Sam Vee. He introduced the column with an editorial entitled “For the Peace of Your Mind.”

For the Peace of Your Mind

We hasten to assure our readers that a piece of my mind...is not intended as a sounding board for peevish gripes, nit-picking beefs, or sundry assortments of righteous indignation, which are usually prefaced by an angry “let me give you a piece of my mind.” Nor is this section of The Journal meant to be a podium for pompous preachments and ex cathedra pronouncements. Nor again is it designed to be a forum for half-baked speculations and warmed-over hypotheses. Least of all is a piece of my mind envisaged as a jamboree of jokes and a shivaree of limericks.
