become available in the US for treatment of acne.

Bacterial infections in adults are generally treated
empirically, with the antibiotic covering most, but not
all, of the potential causative pathogens. For some
infections, culture and sensitivity testing can guide
treatment, allowing for use of narrower-spectrum
antibiotics. The recommended dosages and durations
of antibiotic treatment for common respiratory, skin, and
urinary tract infections are listed in Tables 1-3. Infectious
disease experts now recommend shorter treatment
durations for many infections to reduce the development
of antimicrobial resistance and minimize adverse effects.

highest risk of severe consequences from infective
endocarditis. There is no indication that more limited
use of dental prophylaxis since then has led to an

The drug of choice for patients who require parenteral treatment for malaria is IV artesunate, which is available now from the CDC Malaria Branch (M-F, 8 AM-4:30 PM eastern time, 770-488-7788 or, after hours, 770-488-7100). Artesunate appears to be more effective than quinine1 and safer than quinidine, the other parenteral alternatives in the US. The CDC has supplies of artesunate in Atlanta and in 8 quarantine stations in major airports around the US. It will release the drug for appropriate patients (severe disease or unable to take oral drugs) if it can be supplied as quickly as quinidine, or if quinidine has failed, been poorly tolerated, or is contraindicated.
The herbal artemisinin derivatives artemether and artesunate are used worldwide for treatment of malaria caused by Plasmodium falciparum, but have not been marketed in the US.2,3 About 1500 cases of malaria are diagnosed each year in the US in returning travelers, and about 5% of these have severe disease.4
Artesunate is generally given over 3 days in 2.4 mg/kg doses at 0, 12, 24 and 48 hours. It should be accompanied as soon as possible by an oral drug such as atovaquone/proguanil (Malarone), doxycycline (Vibramycin, and others; not for children <8 years old), clindamycin (Cleocin, and others) or mefloquine (Lariam, and others).

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.

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 pathogenesis of acne is multifactorial: follicular hyperkeratinization, Propionibacterium acnes bacteria, sebum production, androgens and inflammation have all been implicated. P. acnes, a gram-positive microaerophilic bacterium, plays an important role in the development of acne lesions by secreting chemotactic factors that attract leukocytes to the follicle, causing inflammation.

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).
