  • A new survey to monitor hepatitis B vaccination uptake by men who have sex with men: HepB3.
    Helen L Munro

    Dear Editor

    Despite the long-standing recommendation to vaccinate men who have sex with men (MSM) attending genitourinary medicine (GUM) clinics,[1] coverage of vaccination in this group has been difficult to achieve.[2,3] In a study of GUM attendees, post infection immunity (anti-HBs prevalence) was found to be 31% in homosexual men and vaccine coverage to be 40% in London and only 24% outside London.[4] Yee and Rhodes...

  • Grading of Gram-stained vaginal smears, Whats new?
    Anona L Blackwell

    Dear Editor

    I read Ison and Hay’s paper concerning validation of grading of vaginal smears with great interest but am concerned there was no mention of earlier work which closely resembles their new grading system.[1]

    The examination of stained specimens of vaginal secretions for diagnosis, research and classification of vaginal pathology has a long and sometimes confusing history. Medline searches date from...

  • Contact slips when it might be chlamydia
    Peter G Watson

    Dear Editor

    This has been an interesting study of releasing information about the reason for encouraging partner notification. I wonder whether it is possible to have some information about what happened in practice. Presumably, there were some male patients, who had non-gonococcal urethritis diagnosed on their first visit, and, at that time, it was not known whether Chlamydia trachomatis was the cause....

  • Vulval Crohns in absence of bowel involvement
    Benjamin Philip Goorney

    Dear Editor

    We were interested in the case report, "Perianal Crohns Disease masquerading as perianal warts"[1] (August) In which the authors highlight the diagnostic difficulty with other anogenital conditions such as perianal warts. Plus the initial lack of obvious bowel symptoms considered to be the hallmark of Crohns disease.

    We too have recently seen a similar case, but in an older women aged 43 wh...

  • Medical science contraindicates prophylactic male circumcision.
    George Hill

    23 November 2001

    To the Editor:

    Bailis does not support his claim that male circumcision provides significant protection against disease with recent data. He uses antique data that are highly suspect.1

    The Diseker study uses data from inner city STD clinics.2 This introduces significant population bias due to the significantly uneven distribut...

  • Response to: Six monthly chlamydia screening intervals is not ideal
    Gale R Burstein

    Dear Editor,

    Although our study population was homogeneous and Baltimore is known to have high sexually transmitted disease (STD) rates, we believe sufficient evidence exists to support our recommendation of twice yearly chlamydia screening of sexually active females less than 25 years of age. Chlamydia screening in most adolescent female populations yields prevalence rates greater than 10%, except in areas wit...

  • Six monthly chlamydia screening intervals is not ideal
    Rudiger Pittrof
    Dear Editor,

    Burstein and colleagues present interesting data concerning repeat diagnosis of Chlamydia trachomatis in inner city women. Their data may however not support all their conclusions. In their methods section they state that “the frequency of diagnosis of first incident infection was estimated by calculating the median time interval in months between first test and first positive test during the study period a...

  • Cross sectional study of self-selected patients: a valid design to evaluate incidence?
    Rudiger Pittrof
    Dear Editor

    Low and colleagues present a very important paper. They should be given the opportunity to remove my doubts about the validity of their findings: They used a cross sectional design to determine incidence; however, unless the average duration of conditions is known longitudinal studies are required to determine this. The presented study assessed disease status of self-selected participants over a period of...

  • Reactivated syphilis - Author's response
    Hugh Young
    Dear Editor

    Mr McElborough considers it unfortunate that reference labs may have developed their algorithms in the case of conventional syphilis diagnosis and these do little to help with HIV coinfected patients. Guidelines for serological diagnosis in coexisting HIV infection, neurosyphilis and congenital infection are currently under preparation by the (Public Health Laboratory Service) PHLS Syphilis Forum and will...

  • Dangers of generalising
    Linda Semple
    Dear Editor,

    Whilst it is comforting that some research is finally being carried out in depth on the risk of STIs amongst women who have sex with women (WSW), any conclusions drawn from this study for WSW in general need to be handled with a great deal of caution when one looks at the make-up of the subjects and controls.

    For example, over twice as many of the WSW as the control group were current sex workers;...
