Topical eutectic mixture for premature ejaculation (TEMPE): a novel aerosol-delivery form of lidocaine-prilocaine for treating premature ejaculation

To evaluate, in a phase II study, the efficacy and safety of a topical eutectic mixture for premature ejaculation (TEMPE), a metered‐dose aerosol spray containing a eutectic mixture of lidocaine and prilocaine, as a treatment for PE.

Antiretroviral therapy is associated with sexual dysfunction and with increased serum oestradiol levels in men

Our objective was to determine the relationship between highly active antiretroviral therapy (HAART), serum total oestradiol and sexual dysfunction in HIV-infected men. Sexual difficulties were recorded prospectively in a cohort of HIV-negative (or unknown status) gay/bisexual men (MSM) and a cohort of HIV-infected men. The HIV-infected men were divided into those on and not on HAART and by sexuality. Serum total oestradiol and testosterone levels were evaluated where possible. One hundred HIV-negative MSM and 73 HIV-infected men (88% MSM) were analysed. Low libido and erectile dysfunction (ED) were reported in the control group in 2% and 10% respectively. This compared to a prevalence of 26% for both problems in HIV-infected MSM not taking HAART. In those MSM on HAART reduced libido was noted in 48% and ED in 25%. In the group of men taking HAART the mean oestradiol level was 228 pmol/L and was significantly above normal limits. Low libido and ED are more commonly reported in HIV-infected men compared to gay men of negative or unknown status. HAART is associated with a higher prevalence of lack of sexual desire and raised serum oestradiol levels.

Is Entamoeba histolytica in homosexual men a pathogen

Entamoeba histolytica (EH) in homosexual men is generally considered to be pathogenic. To test this hypothesis, the generally accepted features of invasion (haematophagous trophozoites in faeces; high-titre serum antibody; moderate to severe acute inflammatory change; and presence of EH in the mucosa on rectal biopsy) and the zymodeme pattern of cultured trophozoites were assessed in twenty-three EH excretors and eleven control homosexual men. No trophozoites or antibody to EH were found in either group. When other pathogens were excluded, no patient in either group had severe, acute histopathological proctitis. Moderately severe change was seen in 38% of EH excretors and 18% of controls (not significant). All the zymodemes were non-pathogenic. Successful eradication of EH did not result in even a trend towards normalisation of the moderate inflammatory histopathology. There are, therefore, no data here to suggest that EH is a pathogen in homosexual men.

Persistent Genital Arousal Disorder in Women: Case Reports of Association with Anti-Depressant Usage and Withdrawal

Little is known with certitude about the triggers of persistent genital arousal disorder (PGAD) in women, although there appears to be certain common features of the disorder. Women complain of unbidden feelings of genital arousal that are qualitatively different from sexual arousal that is preceded by sexual desire/and or subjective arousal. The majority of women find PGAD distressing and report only brief relief with orgasm. In this article, we describe five women who believe they developed PGAD either after withdrawing from selective serotonin reuptake inhibitor (SSRI) anti-depressants or while using them. We discuss these sexual symptoms in relation to what is already known about prolonged SSRI withdrawal syndromes and the possible etiologies of these conditions. While not a common cause of PGAD, it is possible that use of, and withdrawal from, pharmacological agents contributes to the development of PGAD.

Persistent genital arousal in women – a new syndrome entity

The persistent sexual arousal syndrome (PSAS) is a newly described entity where women become involuntarily aroused genitally for extended periods in time in the absence of sexual desire. Genital vasoengorgement and oedema have been observed. These women are found to be usually very distressed. The cause of the syndrome in the majority of cases is unknown, although a number of women report symptoms after withdrawal from selective serotonin reuptake inhibitors (SSRI) antidepressants. There is no specific therapy at present, although electroconvulsive therapy (ECT) has resulted in clinical improvement in cases where there was concomitant severe depression.

DETECTION OF TREPONEMAL DNA IN THE CSF OF PATIENTS WITH SYPHILIS AND HIV INFECTION USING THE POLYMERASE CHAIN REACTION

The polymerase chain reaction (PCR) was used to detect Treponema pallidum DNA in the cerebrospinal fluid (CSF) of patients with and without syphilis. The CSF from 10 of 19 patients with positive serological tests for syphilis who were being investigated for late syphilis were treponemal DNA-positive. In contrast, the CSF from only one of 30 patients with no known history of syphilis was DNA-positive. CSF from 28 HIV-positive patients was also tested. Fourteen of these patients had central nervous system (CNS) disease and seven were DNA-positive, whereas none of the 14 without CNS disease were DNA-positive. Five of the seven DNA-positive patients had a history of syphilis. Such a history in an HIV-positive patient who had CNS disease was predictive of finding treponemal DNA in the CSF. The PCR had a sensitivity of 47% and a specificity of 93% for detecting a known history of syphilis and is a potentially useful tool in treponemal diagnosis.

Prevalence and service implications of health anxiety in genitourinary medicine clinics

A comparison of the prevalence of health anxiety in genitourinary medicine (GUM) clinics in two UK centres was carried out using a new rating scale, the Health Anxiety Inventory (HAI). The relationship of health anxiety to demographic and clinical variables, and its impact on service contacts, was also examined in one of these centres. 694 patients were assessed and significant health anxiety was identified in 8–11%. HAI scores were stable over time and high levels persisted in the absence of treatment. Attenders with sexually transmitted infections had significantly lower levels of health anxiety than those with other conditions. Contacts with clinic doctors and health advisors in the nine months before and after assessment were significantly greater in those with high health anxiety, with doctor appointments 37% higher in the high HAI group (P = 0.005). Health anxiety is a source of considerable morbidity in GUM clinics deserving further study.

Diagnosing and managing vaginismus

#### Summary points Recent consensus defined vaginismus as, “The persistent or recurrent difficulties of the woman to allow vaginal entry of a penis, a finger, and or any object, despite the woman’s expressed wish to do so.”1 The definition also noted that affected women often avoid intercourse; experience involuntary pelvic muscle contraction; and anticipate, fear, or experience pain. However, it can be difficult to diagnose vaginismus. Women with total vaginismus are unable to tolerate penetration of their vagina by any object, but those with partial vaginismus tolerate penetration with difficulty and pain. The condition can be lifelong (primary) or it can occur after sexual function has been normal (secondary). It can also be situational, occurring only with certain partners or in particular circumstances, or it can be global, occurring independent of partner or circumstances. It is thus a clinical syndrome, not a definitive diagnosis, that consists of overlapping elements of hypertonic pelvic floor muscles, pain, anxiety, and difficulty in penetration. The Diagnostic and Statistical Manual of Mental Disorders , fourth edition (DSM-IV) categorises vaginismus as a sexual pain disorder along with dyspareunia. It describes vaginismus as occurring when “recurrent or persistent involuntary spasm of the musculature of the outer third of the vagina” interferes with intercourse.2 According to this definition, the experience of pain is not necessary for the diagnosis. …

Lymphogranuloma venereum: an emerging cause of proctitis in men who have sex with men

Before 2003, lymphogranuloma venereum (LGV) was rare in developed nations. Several large clusters of LGV in men who have sex with men have been reported across Europe and in the United States of America (USA) since 2003. LGV is caused by L1, L2 and L3 serovars of Chlamydia trachomatis and is a sexually transmitted infection. LGV causes genital ulcers, infected inguinal lymph nodes (buboes) and proctitis/proctocolitis. Treatment with a three-week course of doxycycline prevents rectal strictures, bowel obstruction, bowel perforation and possibly death. Clinicians seeing men who have sex with men with inguinal lymphadenopathy and bowel symptoms should be aware of this current epidemic.

Getting the measure of syphilis: qPCR to better understand early infection

Objectives Until recently, PCR had been used to detect but not quantify Treponema pallidum. To understand infection kinetics of this uncultivable organism, a real-time PCR assay was developed to quantify 47 kDa membrane lipoprotein gene DNA (tpp47). Methods Assay specificity was determined against DNA from humans, skin organisms and sexually transmitted pathogens. tpp47 DNA (Nichols strain) was used to construct a standard curve for T pallidum quantification. Blood and ulcer samples were obtained from 99 patients being investigated or screened for syphilis and tpp47 was quantified. Results The assay was specific, not cross-reactive with other organisms tested and sensitive, with a detection limit of a single copy of tpp47 DNA. For ulcer samples, the assay was 100% sensitive and 97.14% specific. Sensitivity fell to 34.1% for blood samples but specificity remained high (100%). tpp47 DNA was more commonly detected, and at a higher copy number, in blood of patients with secondary infection (sensitivity 57.89%) compared with primary infection. Quantity of tpp47 DNA was higher in primary infection ulcers, especially in HIV-1-positive patients, than in ulcers persisting into secondary disease. Conclusions Quantifying T pallidum provides insight into syphilis infection kinetics: Ulcers of primary disease in HIV-1-positive patients are perhaps more infectious and the presence and load of T pallidum bacteraemia is variable, with a peak in the secondary stage. Quantitative PCR has the potential to map T pallidum infection and to highlight the impact of HIV on syphilis.
