摘要:

Drugs may have negative effects on male libido, erection, ejaculation and orgasm, as well as on fertility, and research on these effects is increasing. Libido may be decreased by drugs that block dopamine or testosterone, or that cause dysphoria. Erection may be decreased by drugs that divert blood flow from the penis, or drugs that affect spinal reflexes. Ganglion blockers may also inhibit erection. Ejaculation may be diminished by drugs that affect spinal reflexes or be inhibited by ganglion blockage. Enervation of the vas deferens and epididymis may be blocked and cause a smaller emission. Retrograde ejaculation may occur due to blockage of the internal urethral sphincter. Orgasm is usually inhibited by the drugs that inhibit ejaculation. Fertility is impaired by drugs that affect sexual performance or spermatogenesis. Major groups of drugs that may affect male sexual function include drugs of abuse, CNS depressants, antihypertensives, anticholinergics, psychotherapeutics, hormones, and cancer therapeutics, in addition to miscellaneous other agents. Information about these drugs has been arranged in tables so that the provider has a convenient reference to use when explaining to men the effect of drugs on sexual response and fertility.

摘要:

Previous studies report that Southeast Asian refugees demonstrate very high incidences of positive reactions to two-step tuberculin testing. In spite of these findings, fiscal restraints have limited the use of two-step testing in some of the centers that screen large numbers of these refugees. In this study, 101 Southeast Asian refugees were studied for their antigenic response to the tuberculin skin test. Forty-nine had positive reactions when the tuberculin skin test was read at 48 hours. Of the 52 refugees who showed a negative reaction at 48 hours, 22 had positive reactions when read a second time, three to five days later. The 28 refugees with negative reactions at both 48 hours and at five to seven days underwent two-step tuberculin testing. Only two of the 28 demonstrated positive reactions with two-step testing. Of the refugees with positive reactions at 48 hours, all but one continued to show positive reactions when the skin test was read a second time, at five to seven days. These findings suggest that a single tuberculin skin test, read at five to seven days, may provide a cost-effective alternative to two-step tuberculin testing for Southeast Asian refugees.

摘要:

Adults with sore throats make 40 million visits to medical facilities each year, and sore throat is the third most common reason for visits to primary care practitioners. While often associated with pharyngitis, a complaint of sore throat may also herald a variety of other underlying disorders, both common and uncommon. These disorders range from local to systemic diseases, and include infectious as well as non-infectious etiologies. This article focuses on the differential diagnosis of sore throat and reviews useful approaches to the evaluation of this prevalent symptom. Specific strategies for history taking, key findings to look for on physical exam and recommendations for the selection of appropriate laboratory studies are included. A summary of management options for the more common problems is also provided.
