Pilot study of cervical cytology screening in a sexually transmitted diseases clinic.

A pilot study of cervical cytology was carried out on 500 new patients at the women's sexually transmitted disease (STD) clinic at this hospital. The aim was to discover the incidence of abnormal smears in order to gauge the worth of cervical cytology as a routine clinic procedure. Information was also gathered on each patient's age, sexual history, method of contraception used, previous smears, and genital infection. Smears showing carcinoma in situ, dysplasia, or warty atypia were regarded as abnormal, and the relevant patients were referred for colposcopy. Seventy-three (14.6%) had abnormal smears. Eight women (1.6%), average age 29.7 years, had cervical intraepithelial neoplasia grade III (CIN III) confirmed by histology. One third of the patients with abnormal smears had genital warts, and the incidence of abnormal smears was greater in patients with genital warts than in those without warts. We concluded that STD clinics are useful places in which to carry out cervical cytology screening, and we noted a positive association between infection with genital warts and abnormal smears.     

Screening for cervical intraepithelial neoplasia and cancer in the Sheffield STD clinic.

I undertook a prospective study of the incidence of histologically confirmed cervical intraepithelial neoplasia (CIN) and cancer in women attending a sexually transmitted disease (STD) clinic, and correlated the findings to cervical cytology reports, age, and history of STD of the affected women. Of 2017 women screened, 75 (3.7%) had dyskaryotic cervical smears. Colposcopically directed biopsy tests gave an overall detection rate of 0.55% for CIN3, which was similar to the national average. The false negative rate was 2.9% and cytology tests alone underestimated the degree of pathological change in 12 (30%) of 40 women with mild dyskaryosis. Women under 20 years old made up 43% of those with CIN1 and 38% of those with CIN2. The detection rate of CIN3 was 0.65% for women aged 15-34, which was higher than the national average and suggested earlier onset of CIN3 in our clinic population. There was a high association between genital warts and cervical precancer. This preliminary study confirms the need for routine non-selective screening of women attending STD clinics by cervical cytology tests, colposcopic examination, and biopsy tests where indicated.     

Cervical cytology screening in sexually transmitted diseases clinics in the United Kingdom. British Co-operative Clinical Group.

During a three month prospective study in 116 sexually transmitted disease (STD) clinics throughout the United Kingdom, out of 17,261 women who underwent cervical cytology, 1167 had dysplastic smears and 115 had positive smears. Positive smears were more prevalent in women attending Welsh clinics than elsewhere in the United Kingdom and increased in incidence with rising patient age. Of all cytological abnormalities reported, 56% of dysplastic smears and 33% of positive smears were found in women aged under 25 years. A subsequent retrospective study in 10 teaching hospitals suggested that past or present genital warts were associated with these cytological abnormalities of the cervix, especially in younger women.     

Increased incidence of cervical cytological abnormalities in women with genital warts or contact with genital warts: a need for increased vigilance?

OBJECTIVE--To determine whether women who have a history of genital warts or whose sexual partners have such a history were more likely to have borderline or dyskaryotic cervical smears than other women. DESIGN--Prospective study conducted over a five month period. SETTING--A genitourinary medicine clinic in Cambridge, UK. PATIENTS--One hundred and eighty five women who attended the clinic during the study period, on whom cervical cytology was performed. Ninety-seven had a history of genital warts and twenty had partners with genital warts. METHODS--Cervical cytology taken by standard methods. Demographic data and sexual history obtained by questionnaire. Colposcopy was performed on patients with a history of warts or wart contact. OUTCOME MEASURED--Relative incidence of cytological abnormalities in the various groups of patients. RESULTS--"Borderline" nuclear change was the most frequent abnormality reported in the wart contact group (six cases) whereas mild dyskaryosis was the most frequent abnormal finding in those women with a history of warts (21 cases). CONCLUSIONS--Women with warts or contact with genital warts were more likely to have borderline or dyskaryotic cervical smears than women without such a history. Recommendations for follow-up of these patients are made.     

Effect of concurrent lower genital tract infections on cervical cancer screening.

BACKGROUND AND OBJECTIVES: Although women attending STD clinics are at high risk for cervical cancer, most STD programmes do not include Papanicolaou (Pap) smears in their routine screening procedures. Concerns regarding reliability of this test in a population with a high rate of active infection are often raised. The objective of this study was to analyse the associations between STD diagnosis/clinical syndromes and unsatisfactory and abnormal Pap smears. METHODS: Retrospective analysis of Pap results and medical records from women attending an inner city STD programme. RESULTS: Of the 1202 patients analysed, 3.2% had squamous intraepithelial lesions (SIL) and 3.5% had smears which were unsatisfactory because of the thickness of the specimen. There were no associations between STD diagnoses and SIL; however, the presence of cervical inflammation was significantly associated with SIL. Pap smears which were unsatisfactory because they were too thick were also associated with the clinical finding of cervical inflammation. CONCLUSIONS: The presence of active infection did not preclude the detection of SIL on Pap smears. The percentage of unsatisfactory smears resulting from inflammation was low.     

Use of the polymerase chain reaction to detect human papillomavirus type 16 in the cervical scrapes of Irish women with varying grades of cervical intraepithelial neoplasia

Objective To assess the prevalence of HPV type 16 among Irish women with various degrees of CIN.
Subjects One hundred and five women with varying degrees of CIN, detected on prior cytological screening, and thirty-two women with cytologically normal cervical smears.
Methods HPV 16 DNA was detected by the PCR technique, with controls against contamination.
Setting The colposcopy clinic in the Rotunda Maternity Hospital, Dublin, and the Virus Reference Laboratory, U.C.D., from October 1991 to April 1992.
Results HPV 16 DNA was detected in 66% of subjects with abnormal cervical cytology, and in 31% of those with normal cervical smears. A higher HPV 16 prevalence was found among those women with CIN III (74%), than among those with CIN I/CIN II (60%).
Conclusions The prevalence of HPV 16 among Irish women with normal cytology and CIN was similar to previous published studies from other areas, with a higher prevalence in those with abnormal cervical cytology. The usefulness of detection of HPV 16 as an indicator of a higher risk of carcinoma of the cervix is discussed.     

Cervical cytology: are national guidelines adequate for women attending genitourinary medicine clinics?

OBJECTIVES: To study whether all women attending a genitourinary medicine (GUM) clinic warrant a cervical smear as part of a routine screen for infection, or whether this "at risk" population is adequately covered by the national screening programme. METHODS: A cervical smear and a screen for sexually transmitted infections (STI) were taken from 900 women attending a GUM clinic between May 1996 and April 1997. RESULTS: Of 812 smears available for analysis, 613 (75.5%) were normal, 176 (21.7%) were mildly abnormal, and 23 (2.8%) were moderately or severely abnormal. In the absence of an STI there was a 14% (37/273) risk of having an abnormal cervical smear. In the presence of cervicitis the risk was 26% (22/84) and with genital warts the risk was 34% (75/215). CONCLUSION: The national screening programme guidelines for cervical cytology should be followed in the GUM clinic. There is no benefit in performing extra smears outside the programme nor in adopting a policy of universal screening.     

Pattern of sexually transmitted diseases and risk factors among women attending an STD referral clinic in Nairobi, Kenya

BACKGROUND: In Kenya, sexually transmitted disease (STD) clinics care for large numbers of patients with STD-related signs and symptoms. Yet, the etiologic fraction of the different STD pathogens remains to be determined, particularly in women. GOAL: The aim of the study was to determine the prevalence of STDs and of cervical dysplasia and their risk markers among women attending the STD clinic in Nairobi. STUDY DESIGN: A cross-section of women were interviewed and examined; samples were taken. RESULTS: The mean age of 520 women was 26 years, 54% had a stable relationship, 38% were pregnant, 47% had ever used condoms (1% as a method of contraception), 11% reported multiple partners in the previous 3 months, and 32% had a history of STDs. The prevalence of STDs was 29% for HIV type 1, 35% for candidiasis, 25% for trichomoniasis, 16% for bacterial vaginosis, 6% for gonorrhea, 4% for chlamydia, 6% for a positive syphilis serology, 6% for genital warts, 12% for genital ulcers, and 13% for cervical dysplasia. Factors related to sexual behavior, especially the number of sex partners, were associated with several STDs. Gonorrhea, bacterial vaginosis, cervical dysplasia, and genital warts or ulcers were independently associated with HIV infection. Partners of circumcised men had less-prevalent HIV infection. CONCLUSION: Most women reported low-risk sexual behavior and were likely to be infected by their regular partner. HIV and STD prevention campaigns will not have a significant impact if the transmission between partners is not addressed.     

Sexually transmitted diseases in rape victims.

From 1 January 1986 to 1 September 1989 124 women presented to the Ambrose King Centre (the department of genitourinary medicine of the London Hospital) alleging rape. Sexually transmitted diseases were found in 36 (29%) women (excluding candidosis and bacterial vaginosis). The commonest organisms detected were Neisseria gonorrhoeae and Trichomonas vaginalis, each being present in 15 patients. Eleven women had genital warts. Chlamydia trachomatis was isolated in six patients, two had herpes simplex virus infection and one patient had pediculosis pubis. Serological evidence of past hepatitis B infection was detected in five women and one patient had antibodies to human immunodeficiency virus. Eighteen of the 36 women (50%) had multiple infections. Six women had abnormal cervical cytology smears, three being suggestive of cervical intraepithelial neoplasia grades II-III. Although it is rarely possible to attribute infection to an assailant, these patients require further counselling, treatment and review. Rape victims are thus a population at risk of having sexually transmitted diseases and screening should be offered.     

Cervical signs of HPV infection in PAP-smear negative women with external genital warts

Forty-eight women with external genital warts, all with normal cervical cytological PAP smears, were examined by means of colposcopy. One cervical biopsy for histological evaluation was taken from each woman, irrespective of the colposcopic findings. Koilocytosis was detected in 18/48 (38%) and dysplasia (CIN-1) in 3/48 (6%) of the patients. The presence of aceto-white lesions on the cervix was significantly associated with abnormal histology; 12 of 17 (71%) aceto-white lesions and 8 to 31 (26%) normal-appearing cervices showed histological changes indicating HPV infection (p less than 0.01). Women with koilocytosis and dysplasia had genital warts for a mean of 201 days compared with 79 days in women with normal cervical histology (p less than 0.01). It is concluded that even the clinically normal appearing cervix frequently is a reservoir for HPV and that colposcopy should be a routine procedure in women with external genital warts, irrespective of the result of the PAP smear, to provide a basis for proper counselling and individual therapy.     

Evaluating a designated family planning clinic within a genitourinary medicine clinic.

OBJECTIVE--To evaluate an integrated family planning clinic (FPC) established by genitourinary medicine (GUM) staff held within a GUM women-only clinic (WOC). DESIGN--A retrospective case note review of women attending the FPC during the first year January-December 1992. RESULTS--One hundred and thirteen women, aged 13-41 years, attended the FPC; 45 were new attenders, six had previously tested antibody positive for the human immunodeficiency virus (HIV), seven were intravenous drug users; 54% had a history of sexually transmitted disease (STD); 17.7% were using no contraception; 32.7% had previous termination of pregnancy (TOP) with 70 TOPs in total. Within three months of FPC attendance 89 (78.8%) women had genital STD screening performed; syphilis, HIV and hepatitis B serology, together with cervical cytology were performed in 77, 18, 13 and 62 women respectively. Infections identified were similar to those identified in the GUM clinic but the prevalence of Chlamydia trachomatis in diagnosed infections was commoner in FPC attenders and epidemiological treatment commoner in GUM attenders. No high grade cytology abnormalities were detected. No positive syphilis or new HIV positive results were identified; five women were found to be hepatitis B surface antibody positive. Contraception was changed in 60.8%. Most frequently supplied was the combined oral contraceptive pill (COCP). At the first FPC attendance six women required post coital contraception (PCC) and five were already pregnant, three suspected it, two were unaware. During the year three women conceived; two used COCP, but were non compliant; one used a diaphragm with unclear compliance. Seven of the eight pregnancies were terminated. Over the following year, 1992-93, contraception was supplied to 42 women; four required PCC; two intentional pregnancies occurred. Only one of the TOP women returned. CONCLUSION--An integrated FPC provides co-ordinated sexual health care. Pregnancy, TOP and FPC re-attendance rates together with improvement strategies are discussed. Avoiding unwanted pregnancy remains a universal challenge.     

Managing women with human papillomavirus changes in cervical cytology.

Of 86 women with cervical cytological evidence of human papillomavirus (HPV) infection who underwent colposcopy, 55 yielded histological confirmation of HPV infection and 17 of them had cervical intraepithelial neoplasia (CIN). Of 51 women followed up six months after cryotherapy of their cervical lesions, 46 showed no evidence of HPV infection in their cervices. Of the patients with CIN lesions, only one out of the 16 followed up had persistent CIN II six months after treatment, which gave a clearance rate of 94% for early CIN lesions treated by this method. Of 62 sexual partners examined, 48 had sexually transmitted infections, 38 of them genital warts. The use of colposcopy with directed punch biopsy is a practical way of managing patients whose cervical smears suggest HPV infection. Cryotherapy is effective in treating histologically confirmed cervical HPV and associated minor CIN lesions. Contact tracing and screening for other sexually transmitted diseases is an integral part of managing genital warts.     

Cost-yield of routine Papanicolaou smear screening in a clinic for sexually transmitted diseases

Because women who attend sexually transmitted diseases clinics have a greater risk of developing cervical cancer than do nonattenders, the authors assessed the cost-yield of routine Papanicolaou screening at the Denver metro Health Clinic. From February 1, 1981 to October 31, 1983, the authors offered Papanicolaou screening to women 25 years of age or older who would sign an agreement accepting responsibility for follow-up. To enhance the cost-yield of identifying a population of women at high risk for a seriously abnormal result who might not otherwise obtain screening, the authors excluded women under 25 years and women with recent smears or conditions complicating interpretation of the smear. Follow-up efforts included a sequence of mailed reminders, telephone calls, certified letters, and home visits. Of 697 initial smears, 40 (5.7%) showed some evidence of atypia, and 12 (1.7%) of these showed dysplasia. Colposcopic or surgical biopsy confirmed dysplasia in three, carcinoma in situ in two, and invasive cervical carcinoma in one. Only 53 patients (7.6%) contacted the clinic for results, and the clinic was able to reach only 49 of 102 women with abnormal smears. The direct cost of the program was about $15,000. Although the rate of dysplasia was relatively low, adequate follow-up proved to be the main barrier to maximizing the cost-yield of Papanicolaou smear-screening in the clinic. It may be necessary for each large sexually transmitted diseases clinic to perform a pilot study to determine whether or not the costs of performing routine Papanicolaou smears are justified by the yields.     

Prevalence of genital human papillomavirus infection in Wellington women.

OBJECTIVES--To determine prevalence of human papillomavirus (HPV) in Wellington women, to identify risk factors for HPV infection, to correlate presence of HPV with cervical cytology, and to identify characteristics of women infected with HPV but with normal cytology. DESIGN--Demographic, social, personal and clinical data were collected by a confidential self-administered coded questionnaire. The presence of DNA from HPV types 6/11, 16 + 18 and 31 + 33 in cervical scrapes was determined by dot-blot DNA hybridisation. All data were correlated with cervical cytology results. SETTING AND SUBJECTS--Two thousand and twenty one women attending family planning clinics in the Wellington region participated in the study. The mean age of participants was 26 years, 33.3% currently smoked, 72.3% used hormonal contraceptives, 31.4% were married, and 91.4% were of European origin. RESULTS--We found 10.9% of the study group infected with HPV. HPV types 16 and/or 18 predominated, being detected in 71.5% of HPV-positive women either alone or with other types. Of those infected 26.2% had multiple infections. Dysplasia (n = 87) or atypia (n = 84) were observed in 26.7% of infected women (n = 221) and 6.25% of uninfected women (n = 1792). Over 8% of women with normal smears were HPV positive, and types 16/18 were most common in these women. CONCLUSIONS--Women with cervical dysplasia or atypia were six times more likely to have HPV infection than other women. The main risk factor for HPV infection, particularly with types 16 and/or 18, was multiple (> 5) sexual partners in the last year independent of other variables. Multivariate analysis of data showed no independent association between HPV infection and ethnicity, educational background, smoking history, marital status, contraceptive use, age at first sexual intercourse, or number of lifetime sexual partners.     

Diagnosis of human papillomavirus infection by dry vaginal swabs in military women

OBJECTIVE: Human papillomavirus (HPV) assays are likely to be used with increasing frequency in clinical management of women with abnormal Papanicolaou smears and in cervical cancer screening. Our objective was to simplify the method of collection of female genital tract specimens. The utility of vaginal dry swabs for HPV diagnosis was evaluated. METHODS: Specimens for cytology and for HPV identification were collected by a clinician from 189 female soldiers attending a military clinic. Three methods of specimen collection for HPV identification were compared: a vaginal dry swab (v-DRY), and vaginal and cervical swabs placed into specimen transport medium (v-STM and c-STM). Swabs were shipped to a STD laboratory for processing. Specific HPV types were identified by a consensus primer based PCR based method. Results from 165 women were evaluable. RESULTS: HPV prevalence by the three methods was similar and ranged from 44.8% to 50.9%. 53 (32.1%) women were HPV positive and 60 (36.4%) women were HPV negative by all three collection methods. With respect to the risk categories of specific HPV types, there was greater agreement between the results from the two vaginal (v-DRY and v-STM) samples (kappa values of 0.69-0.81) than between the cervical (c-STM) and either of the vaginal samples (kappa values of 0.37-0.55). The HPV yield from c-STM was somewhat greater than that from the vaginal specimens but the correlation between cytological abnormalities and HPV was high for all three methods. CONCLUSION: A dry vaginal swab may be an acceptable method of specimen collection for HPV diagnosis.     

Cervical cytology smears in sexually transmitted infection clinics in the United Kingdom

OBJECTIVES: To determine the current practice of smear taking in sexually transmitted infection (STI) clinics within the United Kingdom; what proportion of smears are taken within the national guidelines; whether clinics are screening women not covered by the national screening programme. To compare the abnormality rates of routine and opportunistic (that is, in addition to the screening recommendations) smears; the abnormality rates of smears taken within STI clinics with those taken within the community setting. METHODS: A questionnaire was circulated to all clinics in May 1998. Details of screening practice were requested. The clinics then prospectively collected details of patient's age, GP registration, date and result of previous smear, and current result of all smears taken between 11 May 1998 and 25 May 1998. RESULTS: There were 1828 smears taken in the 2 week period; 504 (27.6%) were opportunistic. Opportunistic smears had marginal significantly increased rates of low grade abnormalities but lower (but not statistically significant) high grade abnormalities than in routine smears. 231 (12.6%) of the women were not registered with a GP so would not be included in the national programme. The national rates of abnormalities were significantly higher in the STI clinics compared with the community setting. CONCLUSION: The majority of smears taken within STI clinics fall within the national guidelines, and 12.6% of the women would probably not otherwise have been screened. The rates of abnormality were significantly higher in the STI clinics but smears taken opportunisticly were less likely to have high grade abnormalities. There is no evidence from this study to support the practice of additional smears in the presence of an effective national cytology screening programme.     

Sexual behaviour of women with human papillomavirus (HPV) lesions of the uterine cervix.

To analyse the epidemiological aspects contributing to the transmission of human papillomavirus (HPV) lesions (flat, inverted, and papillomatous condylomas) of the uterine cervix, we recorded the sexual behaviour of 146 women who consecutively attended the department of obstetrics and gynaecology of Kuopio University Central Hospital with a cervical HPV lesion (with or without concomitant cervical intraepithelial neoplasia (CIN]. Similar data were collected from an age matched group of women with no signs of gynaecological infection. The sexual habits of the women infected with HPV differed from those of healthy controls in most aspects studied, including an earlier onset of sexual activity (p less than 0.05), lower number of deliveries (p less than 0.05), less regular use of contraceptive measures (p less than 0.05), and use of the condom instead of intrauterine contraceptive device (IUCD) (p less than 0.0001). They also differed from controls in giving histories of more frequent episodes of: CIN (p less than 0.005), abnormal Pap (Papanicolaou) smears (p less than 0.0001), sexually transmitted disease (STD) (p less than 0.05), and genital warts (p less than 0.001). Furthermore, they had more multiple sexual partnerships (both past and current) than the controls (p less than 0.0001 and 0.005 respectively), they had not established permanent partnerships as often as the controls (p less than 0.001), and they had a higher frequency of casual relationships (p less than 0.0001). In addition, their own and their partners' sexual hygiene was poorer than in the control subjects (p less than 0.05 and 0.001 respectively). The results show the dramatic influence of sexual behaviour on the transmission of cervical HPV lesions, which are known to be intimately associated with CIN in many cases.     

Epidemiology of genital chlamydial infections in patients with chlamydial conjunctivitis; a retrospective study.

OBJECTIVE: To determine how often chlamydial conjunctivitis is accompanied by a genital chlamydial infection and if there is a correlation between the dominant hand and the eye first infected. METHODS: We retrospectively studied the records of 65 patients with chlamydial conjunctivitis who were referred to the Outpatient Department of Sexually Transmitted Diseases (STD) of the University Hospital Rotterdam by ophthalmologists of the Eye Hospital Rotterdam. The patients have recently been asked by letter if they were left- or right-handed. RESULTS: Twenty of the 37 men (54%) had a positive chlamydial urethral culture. Seventy per cent of these men had no genital symptoms. Eight of the 37 men (22%) had a non-specific urethritis (NSU). Twenty of the 27 women examined (74%) had a positive chlamydial cervical culture. Sixty per cent of these women had no genital symptoms. Eight women with a genital chlamydial infection also had another genital infection. Five women without a genital chlamydial infection had another genital infection. Two women had no genital infection at all. A correlation between the eye infected and left- or right-handedness of the patient could not be found. CONCLUSIONS: A considerable percentage of the patients with a chlamydial conjunctivitis had a concomitant genital chlamydial infection. The majority of them had no genital symptoms. Since patients with chlamydial conjunctivitis and/or their partners possibly have a concomitant genital chlamydial infection, we recommend referral of both patients and sexual partners to an STD clinic for routine examination and systemic treatment when indicated.

Routine anal cytology screening for anal squamous intraepithelial lesions in an urban HIV clinic

OBJECTIVES: The purpose of this study is to describe our experience with routine anal cancer screening using anal cytology, determine risk factors for abnormal anal cytology, and determine if an association exists between cytology and histology in patients with HIV infection. METHODS: Demographics, CD4+ T-cell count, STD history, and cytology and histology data were extracted from medical charts of patients seen between November 1, 2002, and November 30, 2004. Analysis was done using chi2 for comparison of proportions and Student t test for continuous variables. Multivariate analysis was conducted using logistic regression controlling for age, race, sex, CD4+ T-cell nadir, and HIV exposure category. RESULTS: Overall, 276 of 560 of the clinic patients received a screening anal cytology during the study period. Of these patients, 11 were excluded from the analysis and 74 of 265 (27.9%) patients screened had an abnormal anal cytology. Mean age was 44 years, and 68% were men. Forty-nine percent were African American, 34% Caucasian, and 17% Hispanic. Those with an abnormal cytology were more likely to be Caucasian (P = 0.03), and be homosexual or bisexual (P = 0.02). They were also more likely to have a lower CD4+ nadir (142 cells/mm3 vs. 223 cells/mm3, P = 0.005) and CD4+ at time of anal cytology (353 cells/mm3 vs. 497 cells/mm3, P <0.001). Those with an abnormal anal cytology also had higher occurrence of anal disease on perianal visual inspection (30% vs. 9%, P <0.001) and were more likely to have a history of genital warts (23% vs. 12%, P = 0.02) or herpes (35% vs. 22%, P = 0.02). Two patients had anal intraepithelial neoplasia (AIN) I, 2 AIN II, 3 AIN III, and 2 squamous cell carcinoma in situ on histology. There was no apparent association between cytology and histology. CONCLUSION: Routine anal cytology screening is a feasible tool to incorporate into HIV care for patients regardless of gender and HIV risk factors. Its impact on morbidity and mortality warrant further study.
