Ceftriaxone is a third-generation cephalosporin with antibacterial and pharmacokinetic characteristics that make it an excellent choice for the treatment of gonococcal infection and chancroid. Adverse effects are unusual. Clinical efficacy in all reported studies has been excellent. Additional studies are required for further elucidation of the role of ceftriaxone in the treatment of pelvic inflammatory disease and syphilis. Chlamydial infections are not altered by ceftriaxone, and additional treatment is necessary if Chlamydia is present concurrently with Neisseria gonorrhoeae.

Infectious diseases as a Canadian subspecialty, with projections to the year 2000.

Infectious diseases is a relatively new subspecialty in Canada. During the past decade, however, important advances have been made. These include the formation of the Canadian Infectious Diseases Society and the development of the first Royal College of Physicians and Surgeons examinations in the subspecialty of infectious diseases. The majority of Canadians training for practice in the field of infectious diseases are now enrolled in programs in Canada. Despite predictions in the United States of an excess of physicians who specialize in infectious diseases, such a situation has not occurred in Canada. More physicians with training in infectious diseases will be required in Canada in the next decade to fill positions in patient care, microbiology (for individuals with both clinical and laboratory training), research, epidemiology and infection control, programs related to human immunodeficiency virus infections, geographic and international medicine, the pharmaceutical industry, and education and administration. In Canada, the extent to which infectious diseases physicians are involved in these areas varies from that in the United States. This review suggests a continued need for physicians with appropriate training in infectious diseases.

Epidemiologic, clinical, laboratory, and therapeutic features of an urban outbreak of chancroid in North America.

An epidemic of 135 cases of chancroid occurred in Winnipeg, Manitoba, Canada, from July 1975 to September 1977. Probable contributing factors for development of chancroid lesions included male sex, lack of circumcision, and genital trauma. A previous history of venereal disease, sexual contact with a person from a bar or hotel in the core city area, unemployment, alcoholism, American Indian or Métis (mixed American Indian and Caucasian) race, and unstable domestic relationships were often accessory findings for infected patients. The tracing and treatment of lesion-free contacts of patients with chancroid may have contributed to the restriction of the outbreak to the core city area. Nineteen isolations of Hemophilus ducreyi were made, most by the use of a new selective medium. Treatment with a short course of penicillin antibiotics was ineffective for 10 of 16 patients, whereas an adequate course of sulfonamide or tetracycline antibiotics, combined when necessary with drainage of fluctuant inguinal abscesses, was effective therapy for most patients.
