Antibiotic Prophylaxis for Dental Procedures
The Medical Letter on Drugs and Therapeutics • April 29, 2024; (Issue 1701)

Since 2007, antimicrobial prophylaxis for dental
procedures has been recommended to prevent
viridans group streptococcal infective endocarditis
only for patients at highest risk of an adverse
outcome. Limiting use to such patients does not
appear to have led to an increased incidence of
infective endocarditis or increased mortality due to
infective endocarditis.

Addendum: Cephalosporins for Patients with Penicillin Allergy
The Medical Letter on Drugs and Therapeutics • February 18, 2013; (Issue 1410)
A reader who took the online continuing medical education (CME) exam for issue 1406 (Med Lett Drugs Ther 2012; 54:101) pointed out that the first question assumed that a rash following oral administration of...
A reader who took the online continuing medical education (CME) exam for issue 1406 (Med Lett Drugs Ther 2012; 54:101) pointed out that the first question assumed that a rash following oral administration of ampicillin would be due to allergy. Perhaps we should have mentioned in our article on penicillin allergy that late-appearing maculopapular rashes associated with oral ampicillin or amoxicillin are generally considered non-allergic and need not preclude subsequent administration of ampicillin or amoxicillin.

Clostridium difficile infection (CDI) is the most common infectious cause of healthcare-associated diarrhea in adults. The incidence and severity of CDI have increased in recent years with the emergence of an epidemic virulent strain (NAP1/BI/027). Common risk factors include admission to a healthcare facility, increasing age and severity of underlying illness, gastric acid suppression and exposure to antimicrobials, particularly clindamycin, ampicillin, cephalosporins or fluoroquinolones. Patients who develop CDI while receiving a precipitating antibiotic should have the antibiotic discontinued, if possible, or switched to another appropriate antimicrobial with a lower risk of CDI.

Correction: Major Changes in Endocarditis Prophylaxis for Dental, GI and GU Procedures
The Medical Letter on Drugs and Therapeutics • December 17, 2007; (Issue 1276)

On page 100 of the article "Major Changes in Endocarditis Prophylaxis for Dental, GI and GU Procedures", under the section Highest-Risk Procedures, the word "rubber" should have been omitted. Placement of orthodontic rubber bands is not a highest-risk procedure that justifies prophylaxis; placement of orthodontic (metal) bands is. An orthodontic band is a metal ring that surrounds the tooth and is pressed into place causing movement in closely-spaced teeth and sometimes bleeding when the bands are placed close to the gumline.
Major Changes in Endocarditis Prophylaxis for Dental, GI and GU Procedures
The Medical Letter on Drugs and Therapeutics • December 3, 2007; (Issue 1275)

The American Heart Association has issued its revised guidelines for prevention of infective endocarditis. Antimicrobial prophylaxis for dental procedures is now recommended only for patients at the highest risk of severe consequences from endocarditis who are undergoing the highest-risk procedures. Endocarditis prophylaxis is no longer recommended for gastrointestinal (GI) and genitourinary (GU) procedures. When these changes are implemented, the number of patients receiving antimicrobial prophylaxis to prevent endocarditis should decline sharply.

The choice of drugs for treatment of pneumonia depends on the most likely pathogens causing the infection and local antimicrobial resistance patterns. Factors such as severity of illness, presence of co-morbid conditions and whether the infection is community or hospital-acquired also need to be considered.

Meropenem - A New Parenteral Broad-Spectrum Antibiotic
The Medical Letter on Drugs and Therapeutics • September 27, 1996; (Issue 984)

Meropenem (Merrem - Zeneca), a carbapenem similar to imipenem-cilastatin (Primaxin), has been approved by the US Food and Drug Administration for intravenous (IV) treatment of complicated intra-abdominal infections in adults and children and bacterial meningitis in children more than three months old. Imipenem (Medical Letter, 28:29, 1986) has been useful for treatment of serious infections in which broad coverage of nosocomial organisms, including anaerobes, is needed. Other drugs for these indications were reviewed in the Medical Letter article on 'The Choice of Antibacterial Drugs' (volume 38, page 25, March 29, 1996).

Temafloxacin (Omniflox - Abbott) and lomefloxacin (Maxaquin - Searle) are the latest fluoroquinolone antimicrobial agents to be approved by the US Food and Drug Administration (FDA) for oral treatment of various infections. Previously marketed include norfloxacin (Noroxin - Medical Letter, 29:25, 1987), ciprofloxacin (Cipro - Medical Letter, 30:11, 1988), and ofloxacin (Floxin - Medical Letter, 33:71, 1991). Norfloxacin is marketed only for treatment of urinary tract infections, and lomefloxacin only for treatment of urinary tract infections and bronchitis known to be caused by Haemophilus influenzae or Moraxella catarrhalis. Ciprofloxacin and ofloxacin are also available in parenteral formulations.

The gram-positive bacillus Clostridium difficile is the most common identifiable cause of antibiotic-associated diarrhea and pseudomembranous colitis (R Fekety in GL Mandell et al, eds, Principles and Practice of Infectious Diseases, 3rd ed, New York:Churchill Livingstone, 1990, page 863). C. difficile colitis usually develops during or soon after antibiotic treatment. Virtually any antimicrobial agent can cause the disorder, but clindamycin, ampicillin and the cephalosporins have been implicated most frequently. Pseudomembranous colitis was recently reported in five patients who had each taken only a single dose of a cephalosporin (JP Freiman et al, JAMA, 262:902, August 18, 1989).

A penicillin is the drug of choice for treatment of many infections, but allergic reactions to these drugs occur frequently and, rarely, can be fatal. From 5% to 20% of patients have a history of a rash or some other reaction while taking a penicillin, but maculopapular rashes with ampicillin or amoxicillin, especially in children with infectious mononucleosis, are probably not allergic.
