The adolescent patient.

The physician must establish a confidential and trusting relationship with the adolescent patient. All states allow treatment of adolescents over 18 without parental consent and some allow treatment for special problems such as venereal disease or drug abuse before 18. The depressed adolescent often presents with behavioral problems, school failure, or medical symptoms. The medical history should include a description of the pregnancy and delivery, immunizations and childhood diseases, family history of coronary disease, sexual activity, school performance, and drug use. The physical examination should include an evaluation of growth and sexual development, blood pressure determination, a breast examination in older teenagers, and a pelvic examination if the patient is sexually active or if a gynecologic problem is suspected. All adolescent patients need a urine analysis and hematocrit test. Sexually active patients need a serologic test for syphilis, gonorrhea culture, and Papanicolaou smear. Determination of cholesterol and triglyceride are needed when there is a history of a myocardial infarction in a first-degree relative younger than age 50 years.

Development of antibodies reactive in antibody-dependent cellular cytotoxicity in infectious mononucleosis.

Serial sera from patients with infectious mononucleosis were examined for the emergence of antibodies reactive in antibody-dependent cellular cytotoxicity tests, using Epstein-Barr virus-superinfected Raji cells as targets. For this specific purpose, the antibody-dependent cellular cytotoxicity test proved to be of limited sensitivity because only relatively high serum dilutions can be tested dependably, due to prozone effects at low serum concentrations, and because antibody-dependent cellular cytotoxicity reactions at the 5% level are not always statistically significant. Under the conditions of the test, antibody-dependent cellular cytotoxicity-reactive antibodies were not measurable, or only barely measurable, in early-acute-phase sera, but they became detectable during convalescence and increased thereafter, gradually over many months to the range of titers seen in healthy persons after long-past-primary Epstein-Barr virus infections. The percentages of antibody-dependent cellular cytotoxicity ultimately attained were on the order of 20% in most patients and healthy individuals, but in others did not exceed 10%. The likely identity of the antibodies reactive in the test with antibodies to late Epstein-Barr virus-determined cell membrane antigens has been discussed.

Infectious mononucleosis and the Epstein-Barr virus.

Recent elucidation of the relationship between the Epstein-Barr virus and infectious mononucleosis has resulted in the development of new diagnostic serological tests, and has amplified our knowledge of the epidemiological and clinical aspects of the disease. The history, epidemiology, clinical characteristics, diagnostic features, and therapy of infectious mononucleosis are reviewed. This is done in the light of recent knowledge concerning the Epstein-Barr virus as well as previous studies employing the traditional diagnostic criteria of heterophil positivity, the classical clinical symdromes, and characteristic changes in the blood cell count. Immunological studies concerning host resistance and its occasional failure are reviewed with particular reference to T and B lymphocyte activity in the disease.
