To avoid social isolation, discrimination, or verbal or physical abuse, many men who have sex with men (MSM), especially young and minority MSM, do not disclose their sexual orientation. Young MSM who do not disclose their sexual orientation (nondisclosers) are thought to be at particularly high risk for human immunodeficiency virus (HIV) infection because of low self-esteem, depression, or lack of peer support and prevention services that are available to MSM who are more open about their sexuality (disclosers). However, the risks for HIV infection and other sexually transmitted diseases (STDs) are unknown for nondisclosers. To better understand the prevention needs of young MSM, CDC analyzed data from the Young Men's Survey (YMS) to compare HIV/STD risk differences between nondisclosers and disclosers. This report summarizes the results of that analysis, which indicate that 8% of 637 nondisclosers were infected with HIV compared with 11% of 4,952 disclosers. Among blacks, the prevalence of HJV infection was 14% among 199 nondisclosers compared with 24% among 910 disclosers.

This study examined awareness of and attitudes about highly active antiretroviral therapies (HAARTs) among adolescent and young men who have sex with men (MSM). As part of the multisite Young Men's Survey, 813 MSM aged 15-22 years who attended public venues in two cities were questioned about HAART in 1997-1998. Overall, 45.1% had heard of HAART, 61.6% in Seattle, Washington, and 35.0% in New York City. MSM in New York City who were the youngest, men of color, men who were human immunodeficiency virus (HIV) antibody negative, and men who resided in New Jersey were significantly less likely to be aware of HAART. Attitudes about HAART were not associated with sexual risk behaviors. Prevention efforts among young MSM should focus on other determinants of risk, but also include information on the changing nature of HIV therapies.

Sexual transmission of the human immunodeficiency virus (HIV) continues to pose a public health problem worldwide. Men who have sex with men are still at differential risk of infection. Although there is evidence to claim that HIV can be transmitted by oral sex, the perception of this risk is ambiguous and relates paradoxically to behavior change. New models of risk perception must be developed in various areas of knowledge to obtain a fuller understanding of this phenomenon.

In human immunodeficiency virus infection as well as in related syndromes, cervico-facial and otorhino-laryngologic manifestations are current. A retrospective study in Oto-Rhino-Laryngology service of Brazzaville University Hospital from December 1995 to November 2001 has been reported. 253 patients were selected from a total of 1352 consultations. The study population is young (average age: 34 +/- 4.8 years), and most of the patients are 30 to 49 years old (75.9%). Men represent 51% and women 49%. Although sexual multipartnership (59.7%) is the main risk factor, traditional practices (22.8%) are not neglictible in Africa. Among all cases, human immunodeficiency virus type 1 is found in 72.3% of cases. The affections are located in the neck (40.5%), ear (24.9%), pharynx (17.3%), rhinosinus (13.3%), oral cavity and vestibule (2.7%) and larynx (1.3%). These main affections are represented by: parotidosis (20.1%), peripheric facial paralysis (15.4%), pharyngeal candidiasis (14.6%), sinusitis (14.2%) and ganglial tuberculosis (11.5%). Lymphoma (7 cases), kaposi's sarcoma (7 cases) and epidermoid carcinoma (1 case) are the malignant affections identified in 15 cases (6%). The diagnosis of some affections like cystic parotiditis (11%), noma (1.6%), African histoplasmosis (0.4%) and rhinoscleroma (0.4%) constitutes this study particularity The Oto-rhino-laryngologist's role is important in early diagnosis of HIV infection as well as in the followed-up of patients.

This study was performed to investigate whether men who have sex with men visiting the sexually transmitted diseases clinic, and those participating in a gay cohort were different with regard to demographic characteristics, sexual behaviour and sexually transmitted diseases (STD)/human immunodeficiency (HIV) virus prevalence. Data from men who have sex with men presenting at the sexually transmitted diseases clinic (group I; n = 318) were compared with data from men participating in a cohort (group II; n = 286). All males underwent a routine venereological examination. Men in group II were more often older (p < 0.0005), of Dutch descent (p < 0.0005) and had more sex partners (p < 0.0005). New cases of HIV infection were detected far more often in group I (p = 0.04). Also, urethral gonococcal infection was significantly more prevalent in group I (p = 0.003). Multivariate analyses showed that males presenting at the STD clinic (group I) were at higher risk for urethral gonorrhoea. The higher prevalence of HIV infection in group I was associated with a higher prevalence of recent STD, more concomitant urethral gonorrhoea infections at the time of visit, over 10 sex partners in the previous 6 months, and non-Dutch descent.

Positive transcription elongation factor b (P-TEFb) is an RNA polymerase II elongation factor which exists as multiple complexes in human cells. These complexes contain cyclin-dependent kinase 9 as the catalytic subunit and different cyclin subunits-cyclin T1, T2a, T2b, or K. Cyclin T1 is targeted by the human immunodeficiency virus (HIV) Tat protein to activate transcription of the HIV provirus. Expression of this P-TEFb subunit is highly regulated in monocyte-derived macrophages (MDMs). Cyclin T1 is induced early during differentiation and is shut off later by proteasome-mediated proteolysis. Cyclin T1 can be reinduced by pathogen-associated molecular patterns (PAMPs) or HIV infection. In this study, we analyzed regulation of P-TEFb in MDMs by examining 7SK small nuclear RNA and the HEXIM1 protein; these factors associate with P-TEFb and are thought to regulate its function. 7SK and HEXIM1 were induced early during differentiation, and this correlates with increased overall transcription. 7SK expression remained high, but HEXIM1 was shut off later during differentiation by proteasome-mediated proteolysis. Significantly, the cyclin T2a subunit of P-TEFb was not shut off during differentiation, and it was not induced by activation. Induction of cyclin T1 by PAMPs was found to be a slow process and did not involve an increase in cyclin T1 mRNA levels. Treatment of MDMs with PAMPs or a proteasome inhibitor induced cyclin T1 to a level equivalent to treatment with both agents together, suggesting that PAMPs and proteasome inhibitors act at a similar rate-limiting step. It is therefore likely that cyclin T1 induction by PAMPs is the result of a reduction in proteasome-mediated proteolysis.

Methamphetamine (meth) is a highly addictive stimulant that gained widespread popularity in California in the 1980s and has since spread to most regions of the United States, including rural areas. Analyses of survey data among noninjection-drug users from California in the mid-1990s determined that, among heterosexual persons and among men who had sex with men (MSM), meth users reported more sex partners, were less likely to report condom use, and were more likely to report sex in exchange for money or drugs, sex with an injection-drug user, and history of a sexually transmitted disease (STD). Subsequent studies among MSM have indicated an association between meth use and sexual risk behaviors, syphilis infection, and incidence of human immunodeficiency virus (HIV) infection. Subsequent studies among heterosexual populations have been less extensive than those among MSM and often have not used population-based samples nor adjusted for possible confounders. To further assess the association between meth use and high-risk sexual behaviors among heterosexual men, the California Department of Health Services, Office of AIDS, analyzed population-based data from five northern California counties in the HEY-Man (Health Evaluation in Young Men) Study. This report summarizes the results of that analysis, which determined that recent meth use was associated with high-risk sexual behaviors, including sex with a casual or anonymous female partner, anal intercourse, and sex with an injection-drug user. The results suggest the need for states to consider including referrals to meth prevention and treatment programs in their HIV prevention programs and for broader assessment of the relation between meth use and high-risk sexual behaviors.

The most common site of Neisseria gonorrhoeae infection is the urogenital tract. Men with this infection may experience dysuria with penile discharge, and women may have mild vaginal mucopurulent discharge, severe pelvic pain, or no symptoms. Other N. gonorrhoeae infections include anorectal, conjunctival, pharyngeal, and ovarian/uterine. Infections that occur in the neonatal period may cause ophthalmia neonatorum. If left untreated, N. gonorrhoeae infections can disseminate to other areas of the body, which commonly causes synovium and skin infections. Disseminated gonococcal infection presents as a few skin lesions that are limited to the extremities. These legions start as papules and progress into bullae, petechiae, and necrotic lesions. The most commonly infected joints include wrists, ankles, and the joints of the hands and feet. Urogenital N. gonorrhoeae infections can be diagnosed using culture or nonculture (e.g., the nucleic acid amplification test) techniques. When multiple sites are potentially infected, culture is the only approved diagnostic test. Treatments for uncomplicated urogenital, anorectal, or pharyngeal gonococcal infections include cephalosporins and fluoroquinolones. Fluoroquinolones should not be used in patients who live in or may have contracted gonorrhea in Asia, the Pacific islands, or California, or in men who have sex with men. Gonorrhea infection should prompt physicians to test for other sexually transmitted diseases, including human immunodeficiency virus.

Men who are seropositive for human immunodeficiency virus (HIV) or hepatitis C virus now can father children safely, thanks to sperm washing and nested polymerase chain-reaction techniques, followed by intracytoplasmic sperm injection. However, in a small percentage of such patients, it is impossible to recover spermatozoa after said procedures because of their highly impaired spermatogenesis. We have established that less rigorous methods, such as repeated centrifugation, yield nested polymerase chain-reaction HIV- and hepatitis C virus-negative specimens, even in sperm samples from men with severe oligoasthenozoospermia.

Perspectives of public health generally ignore culture-bound sexual health concerns, such as semen loss, and primarily attempt to eradicate sexually transmitted infections (STIs), including human immunodeficiency virus (HIV). Like in many other countries, sexual health concerns of men in Bangladesh have also received less attention compared to STIs in the era of AIDS. This paper describes the meanings of non-STI sexual health concerns, particularly semen loss, in the masculinity framework. In a qualitative study on male sexuality, 50 men, aged 18-55 years, from diverse sociodemographic backgrounds and 10 healthcare practitioners were interviewed. Men considered semen the most powerful and vital body fluid representing their sexual performance and reproductive ability. Rather than recognizing the vulnerability to transmission of STIs, concerns about semen were grounded in the desire of men to preserve and nourish seminal vitality. Traditional practitioners supported semen loss as a major sexual health concern where male heritage configures male sexuality in a patriarchal society. Currently, operating HIV interventions in the framework of disease and death may not ensure participation of men in reproductive and sexual health programmes and is, therefore, less likely to improve the quality of sexual life of men and women.
