Chlamydia trachomatis conjunctivitis in the pre-pubertal child.

Much is reported in the literature about the transmission and presentation of Chlamydia trachomatis conjunctival infection in the neonate; however, there is a paucity of information available on infection in the older pre-pubertal child (>3 years of age). We present the case of a 7-year-old girl, referred for assessment at the sexual assault referral centre following the diagnosis of unilateral C. trachomatis conjunctivitis. This child underwent a rigorous multiagency child protection process, with input from medical professionals, social services and the police to investigate the possibility of child sexual abuse (CSA). However, a group consensus was reached that non-sexual close contact transfer of C. trachomatis from the mother was the most likely mode of transmission and cause of infection. We aim to take the reader through the complex path to this conclusion, the approach to sexually transmitted infections and potential CSA and what is currently known about chlamydial conjunctivitis in children beyond the neonatal period.

Persistent genital arousal and restless genitalia: sexual dysfunction or subtype of vulvodynia?

We conducted a literature review of patients' conditions described under persistent genital arousal disorder and restless genital syndrome, vulvodynia and male genital skin pain of unknown aetiology (penoscrotodynia). Our aim is to improve the understanding of the condition, unify nomenclature and promote evidence-based practice. The most prominent symptom in persistent genital arousal disorder and restless genital syndrome is a spontaneous, unwelcomed, intrusive and distressing vulval sensation. There are similarities between the clinical presentation of vulvodynia, penoscrotodynia, persistent genital arousal disorder and restless genital syndrome patients. The aetiology of persistent genital arousal disorder and restless genital syndrome, similar to vulvodynia, could be better explained in terms of neuro-vascular dysfunction, genital peripheral neuropathy and/or dysfunctional micro-vascular arterio-venous shunting. Erythromelalgia lends itself to explain some cases of restless genital syndrome, who have concurrent restless legs syndrome; and therefore draw parallels with the red scrotum syndrome. The published literature supports the concept of classifying restless genital syndrome as a sub-type of vulvodynia rather than sexual dysfunction.

The long-term efficacy and safety of a testosterone mucoadhesive buccal tablet in testosterone-deficient men.

What's known on the subject? and What does the study add? Striant® SR is the only available buccal delivery system for testosterone replacement therapy. Previous pharmacokinetic studies have shown that Striant SR effectively produces physiological serum testosterone levels in hypogonadal men. Efficacy and safety data from previously unpublished studies over 2 years of continuous use indicate that Striant SR is effective long term in maintaining serum testosterone within a physiological range, is well tolerated and has a high level of patient acceptance. Striant® sustained-release (SR) is a mucoadhesive buccal tablet (30 mg testosterone, The Urology Company) that adheres to the gum surface in the mouth providing controlled- and sustained-release of testosterone over a 12-h dosing period, offering a unique and rational method of testosterone delivery. Striant SR is indicated for testosterone-replacement therapy (TRT) for male hypogonadism when testosterone deficiency has been confirmed by clinical features and biochemical tests. Pharmacokinetic studies have shown that testosterone is released from Striant SR in a manner similar to the normal daily rhythm of endogenous testosterone secretion, with serum levels rising rapidly after insertion and peak levels reached by the second 12-hourly dose with no accumulation over time. In clinical trials involving hypogonadal men receiving Striant SR for up to 2 years, mean serum testosterone levels have always remained within the normal range. Striant SR is well tolerated, with gum-related disorders (such as irritation, inflammation and gingivitis) and taste perversion being the most commonly reported adverse events, reported by 5.6-16.3% and 3.0-4.1% of patients, respectively. Once patients have become accustomed to it, Striant SR has a high level of patient acceptance. In a long-term study, 90% of patients rated the twice-daily dosing as acceptable, just under half preferred it to other forms of TRT that they have used and 96% found it to be cosmetically acceptable. There is no clinically significant risk of testosterone transfer from Striant SR, as any testosterone that may be present in the saliva when swallowed is subject to extensive first-pass hepatic metabolism. It is pertinent to note that the saliva of eugonadal men contains similar levels of endogenous testosterone. Buccal delivery is particularly suitable where easy and rapid reversal of treatment might be required (such as in late-onset hypogonadism) and where there is a need to avoid the potential for transfer of testosterone to women and young children.

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

OBJECTIVE: 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. PATIENTS AND METHODS: Men with PE (Diagnostic and Statistical Manual-IV definition) aged 18-75 years were randomized into a double-blind, placebo-controlled study in the UK and the Netherlands. Efficacy variables included the mean change in intravaginal ejaculatory latency time (IELT) from baseline and the proportion of patients who achieved an IELT of > or = 4, > or = 3 or > or = 2 min on two occasions, and the effect of TEMPE on the index of ejaculatory control (IEC) and sexual quality-of-life (SQoL) scores of patients and their partners. Safety and adverse event data were also collected. Fifty-four patients were randomized and received study treatment. RESULTS: The observed mean change in IELT from baseline to the end of the treatment period was 3.8 min in the TEMPE group and 0.7 min in the placebo group, and when adjusted for baseline and centre was 2.4 times higher in the TEMPE than the placebo group (P < 0.01). The efficacy of TEMPE in increasing IELT was further supported by positive trends in the other efficacy endpoints. The proportion of men who had an IELT time > or = 2, > or = 3 or > or = 4 min on two occasions after treatment was 11/20 (55%), 8/20 (40%) and 5/25 (20%) in the TEMPE group, and 8/23 (35%), 3/23 (13%) and 3/23 (13%) in the placebo group, respectively, although these differences were not statistically significant. Improvements in IEC and SQoL (male and female) scores also showed trends towards greater efficacy for TEMPE than placebo. In all, 35 of 42 (83%) patients considered the spray easy to use. Mild to moderate local numbness occurred in three (12%) of the TEMPE-treated patients but did not lead to discontinuation. CONCLUSION: Topical treatment with TEMPE produced a statistically and clinically significant increase in IELT compared with placebo, and resulted in positive trends in ejaculatory control and SQoL. TEMPE was considered easy to use and was well tolerated. The data support the conduct of further large-scale studies to establish the utility of TEMPE as a first-line treatment for PE.

Evaluation of the Sexual Assessment Monitor, a diagnostic device used to electronically quantify ejaculatory latency time: findings from three studies.

OBJECTIVE: To validate the Sexual Assessment Monitor (SAM), a novel apparatus designed to collect electronic data on ejaculatory latency time (ELT) for diagnosing premature ejaculation (PE), and for accurately measuring treatment outcomes in clinical trials. PATIENTS, SUBJECTS AND METHODS: Men with PE, and healthy volunteers aged 18-75 years, were enrolled in three open-label studies, conducted in the UK. The SAM, which consists of a control box with two front attachments, a vibrator and sensor, was attached to the penis. The vibrator, which provides stimulation, was positioned at the frenulum using a soft cuff; the vibrator intensity was set at 80 units for most subjects. The sensor is an indium-gallium elasticated loop, which was positioned around the base of the penis to detect ejaculatory pulses. These pulses were transmitted to a data recorder in the control box. The data, which are displayed graphically as traces, were automatically classified by a computer-generated algorithm to quantify ELT. RESULTS: In all, 53 healthy volunteers and 58 men with PE provided 213 and 195 evaluable records, respectively. Most were complete records (99% and 96%). The pooled data showed that the ELT was much higher for healthy volunteers than for men with PE (geometric means: 687 vs 169 s, respectively), with a healthy volunteer to PE patient ratio of 2.87 (P < 0.001). Only 6.3% of subjects reported mild adverse events, which were unrelated to the SAM. CONCLUSIONS: These open-label studies show that the SAM can consistently and safely measure times to erection (from the start of vibration) and ejaculation, and ELT in healthy volunteers and men with PE. These findings show that the SAM has the potential to become the 'gold standard' in the diagnosis of PE and in clinical trials design.

Available and future treatments for erectile dysfunction.

There is now a range of treatments for patients with erectile dysfunction (ED) beyond the psychosexual counselling and surgical implants that were the only available management options for many years. Oral treatments, which are minimally invasive, are the favoured first-line option for treatments and include the phosphodiesterase-5 (PDE5) inhibitors, and dopamine agonists such as apomorphine. Psychosexual counselling may still be an appropriate treatment, on its own or in combination, in a minority of patients who do not respond to oral treatment, or where an origin for the ED is likely from the history. The PDE5 inhibitors, sildenafil, tadalafil, and vardenafil, have proven to be effective and well tolerated and facilitate erectile function. Apomorphine is also effective, but causes nausea in a minority of men. The alpha-receptor antagonist yohimbine has been found to be effective in some placebo-controlled trials, but its effectiveness is probably inadequate for treatment of most ED. Intracavernosal injection of drugs such as prostaglandin E1, papaverine, and phentolamine (sometimes in combination) is an effective but invasive treatment. Other treatments include testosterone, vacuum-pump treatment, surgery, and surgical implants, and tend to be used where patients do not respond to oral treatment and counselling.

Treatment of erectile dysfunction.

Erectile dysfunction (ED) is an inability to attain or maintain an erection sufficient for satisfactory sexual intercourse. It is an undertreated and underdiagnosed condition that can be due to vasculogenic, neurogenic, hormonal and psychogenic factors. Effective treatment of ED should restore quality of life and allow patients to return to the sex life they had before. Current therapeutic options include non-pharmacological treatments, locally administered drugs and oral therapies. The oral phosphodiesterase-5 (PDE5) inhibitors are considered first-line treatments of ED and have revolutionized ED management in the last five years. Three PDE5 inhibitors are currently available, sildenafil, vardenafil and tadalafil. They are all effective with similar efficacy and good safety profiles. However, tadalafil has the added benefit of a broad window opportunity offering patients more freedom to choose when to initiate sexual activity.
