Genital human papillomavirus infection among patients attending an STD clinic.

OBJECTIVES--To determine the prevalence of human papillomavirus (HPV) infection in patients, male and female, attending a clinic for sexually transmitted diseases (STDs). DESIGN--A randomly selected group of patients representative of the population studied and first-time visitors to the STD clinic, were asked to participate in the study. Samples from the skin and mucous membranes of the lower genital region were taken for cytological analysis by the polymerase chain reaction (PCR) method for HPV DNA. The patients then underwent colposcopy or peniscopy after acetic acid application. SETTING--Department of Dermatology and Venereology, University Hospital, Uppsala, Sweden. SUBJECTS--A total of 131 patients, 66 women and 65 men, attending the clinic for various reasons. RESULTS--At colposcopy/peniscopy, 18 patients (10 men and 8 women) had lesions typical of, and 24 (12 men and 12 women) suspicious of HPV infection. With the PCR technique HPV DNA was detected in 72% of the patients with typical lesions and in 54% of those with suspicious lesions. CONCLUSION--Nearly one-third or 30.5% of these randomly selected patients in a Swedish STD clinic were infected by HPV. The diagnosis was made by clinical inspection and/or by HPV DNA analysis with PCR.

Comparison of a one-step and a two-step polymerase chain reaction with degenerate general primers in a population-based study of human papillomavirus infection in young Swedish women.

The prevalence of human papillomavirus (HPV) infection in cervical cell scrapes from young women was determined by polymerase chain reaction (PCR) by using general primer pairs localized within the L1 region. With a one-step general PCR, 5.9% (35 of 590) of young women in a population-based study were found to contain HPV DNA. The proportion of HPV-positive women increased with age, from 1.4% (1 of 69) among women aged 19 years to 9.2% (13 of 142) among women aged 25 years. Among the cervical scrapes from women with normal cytology, 5.6% (30 of 539) harbored HPV DNA. A total of 5 of 19 (26.3%) of the women with pathological signs were positive for HPV DNA. By a two-step PCR, using nested general primers, 20.3% (118 of 581) of all women were shown to contain HPV DNA. The proportion of HPV-positive women also increased with age, from 17.4% (12 of 69) among women aged 19 years to 31.9% (43 of 135) among women aged 25 years, when the two-step PCR was used. Some 19.2% (102 of 530) of cervical scrapes from women with normal cytology contained HPV DNA. Among the women with pathological signs, 16 of 19 (84.2%) were positive for HPV DNA. The HPV DNA-positive specimens were demonstrated to contain HPV type 6, 11, 16, 18, 31, 33, 35, 39, 40, 45, 55, or 56. The most prevalent HPV types were 6 (2.0%) and 16 (2.7%). More than one type was found in 16 specimens. Sixty HPV-positive samples could not be typed.

Oligonucleotide primers for DNA amplification of the early regions 1, 6, and 7 from human papillomavirus types 6, 11, 16, 18, 31, and 33.

Human papillomavirus (HPV) type-specific sequences required for polymerase chain reaction (PCR) mediated amplification of HPV DNA sequences are presented. One primer pair within the E1 open reading frame (ORF) was shared by HPV 6, HPV 11, HPV 16, and HPV 31, whereas the other primer pair within the E1 ORF was specific for HPV 16. Eight primer pairs from the E6 and E7 ORFs specifically detected HPV 6, HPV 16, HPV 18, and HPV 33 sequences. This system has been used for detection of HPV DNA in biopsies, cytological smears and sections of formalin-fixed tissues.

Detection of human papilloma virus in women referred for colposcopy. A comparison between different diagnostic methods.

Various methods presently available for the diagnosis of genital Human Papilloma Virus (HPV) were compared regarding their sensitivity in women referred for specific diagnosis and treatment because of atypical Pap smears or clinically suspected neoplasia. Colposcopic examination was performed in all cases. In addition to taking a second Pap smear, cell suspensions were made from 105 women and analysed by the Filter In Situ Hybridization (FISH) technique and tested for HPV 6 + 11 and HPV 16 + 18 + 31. The FISH technique was also used for the possible detection of HPV-DNA in a reference material comprising 119 apparently healthy women with normal Pap smears. Colposcopically directed cervical biopsies in altogether 196 specimens were obtained from 155 women for histopathological examination and also for the detection of HPV-DNA by the Southern blot hybridization technique. These specimens were tested for the presence of HPV 6, 11, 16, 18, 31 and 33. Three per cent of the women with and 34% without cytological signs of HPV in Pap smears had cervical intraepithelial neoplasia (CIN) III according to histopatology. CIN III was present in 35% of biopsies with and 59% of biopsies without histological signs of HPV in the biopsies. Altogether 46% of the women were HPV-DNA positive. Of the women analysed by Southern blot, 39% were HPV-DNA positive. Of the samples analysed by FISH, 27% with atypical cells were HPV-DNA positive, compared with 11% of the samples from reference women with normal cytology.(ABSTRACT TRUNCATED AT 250 WORDS)

Local anesthesia of the genital mucosa with a lidocaine/prilocaine cream (EMLA) for laser treatment of condylomata acuminata: a placebo-controlled study.

The time of onset and duration of local anesthesia of a lidocaine/prilocaine cream (EMLA) applied to the genital mucosa were assessed in a double-blind study. Eighty women with condylomata on their genital mucosa were randomly allocated to either EMLA (N = 60) or placebo cream (N = 20) between 1-75 minutes before CO2 laser treatment. The pain was evaluated by the patient on a visual analogue scale. The most effective degree of anesthesia was achieved after 5-15 minutes' application of EMLA. The patients given EMLA, regardless of application time, felt significantly less pain than the patients given placebo. EMLA could provide an alternative to general anesthesia in patients with extensive condylomata on the genital mucosa.

Menstrual variation of estrogen receptor content in vaginal tissue.

Estrogen receptor content in vaginal tissue was quantified in 12 healthy female volunteers during the menstrual cycle. Epithelial biopsies were obtained at cycle days 10 and 21 and investigated by a monoclonal enzyme immunoassay. Measurable amounts of estrogen receptors were found in all women at both sampling occasions. In women with an ovulatory menstrual cycle, a significant fall in V-receptor content was recorded during the luteal phase. Structural and functional changes in the vaginal epithelium during the menstrual cycle may be important for the diagnosis and susceptibility to certain viral infections.

Papilloma virus infection of the vulva.

Analyses of the possible presence of human papilloma virus (HPV) DNA were performed on 84 biopsies from 50 women with clinically and histopathologically suspected HPV infection of the vulva. The colposcopic criteria for inclusion in the study were: acetowhite flat lesions with or without fissures and/or diffuse hyperplastic mucosa with a granulated or filamental surface. Directed biopsies for histopathology and DNA hybridization (dot-blot and Southern-blot) were taken. All women had histopathological evidence of HPV infection. Twelve women had cervical and/or vulvar neoplasia. HPV DNA could be demonstrated in the vulvar biopsies from 24 women; 13 women had HPV 16, 3 had HPV 18, HPV 31 and HPV 33, respectively. In addition, 10 biopsies contained HPV DNA of unknown types. Fifty-five percent of granulated and filamental lesions and 43% of flat lesions with or without fissures were positive for HPV DNA. 34 women had one or more of the following symptoms: itching, burning, dyspareunia, discharge, fissures, dryness and dysuria. Papillomavirus vulvitis is a sexually transmitted disease which may cause recalcitrant symptoms and/or concomitant neoplasia. It is thus important to recognize the different symptoms and signs of this disease.

Risk factors for occasional and recurrent wheezing after RSV infection in infancy.

Sixty-seven children who were hospitalized with a verified RSV infection were reexamined after 4 years at the age of 4 to 7 years. Twenty-four children had had no subsequent respiratory symptoms, 22 had wheezed 1-3 times and 21 had recurrent wheezing. A family history of atopy and a personal history of neonatal respiratory problems were more common in the group with recurrent wheezing, whereas paternal smoking was more frequent in the group with occasional wheezing. RSV infection in early infancy was more related to occasional wheezing than recurrent episodes. The spirometric data obtained from the force expirograms were normal, compared to the predicted normal values. In the children with recurrent wheezing, however, the values for PEF and the MEF25 were significantly lower in comparison with all the other children showing a mild obstruction.

Sensitization of children in the Stockholm area to house dust mites.

Atopic sensitization of children in the Stockholm area to house dust mites (HDM) was investigated in a case-control study. Sixty children with and 60 without positive skin prick tests for HDM were matched for age and sex. HDM-sensitized children had previously more often lived in other areas known to be mite infested than the control children. Sensitization to mites was related to dampness in the homes, but no significant relationship was found to the type of residence, frequent visits to a summer house in the archipelago or parental smoking. Dust samples from mattresses of the children with the strongest positive reactions to mites in skin prick tests and the respective controls were subjected to an enzyme immunoassay, to measure the content of the major allergens of the Dermatophagoides (D.) species D. pterinyssinus, D. farinae and D. microceras. Mattress dust samples from the beds of HDM-sensitized children contained significantly higher HDM antigen concentrations than those from the beds of controls. Private houses contained significantly more HDM antigens than flats and 10 of 11 homes in which a dampness problem was recognized contained mite antigens. It is postulated that mite infestation is increasing in the area, energy-saving measures creating improved conditions for HDM survival.

Morphometric characteristics of the vaginal epithelium during the menstrual cycle.

Vaginal biopsies were obtained in 5 healthy women every third day during the menstrual cycle. The specimens were examined with morphometric technique and the mean nuclear size was correlated to values of estradiol and progesterone and caryopycnotic index. Cyclical changes of the histological appearance of the epithelium could be demonstrated. During estrogen influence a proliferation and maturation of the vaginal mucosa was seen whereas addition of progesterone was associated with a shedding of the superficial cell layers and a steady state of the basal part of the epithelium. At ovulation the epithelium reached maximal thickness and maturity. The histological architecture at this time may resemble a human-papilloma-virus (HPV)-infected mucosa. The difficulties in distinguishing an HPV-infected epithelium from normal are discussed.

Clinical characteristics of papillomavirus-vulvovaginitis. A new entity with oncogenic potential.

The purpose of this paper is to describe the clinical characteristics of HPV-vulvovaginitis. Clinical symptoms were recorded in 74 women with the diagnosis of papillomavirus vulvovaginitis. The diagnosis was established by colposcopic examination, immunological detection of viral structural antigen, and selected biopsies. Patient data were obtained from medical records and by interviews. Discharge, itching, burning, fissures and dyspareunia were typical symptoms. Discharge was more frequent in women with vaginal localization of the HPV infection, whereas itching and burning were the predominant complaint when the HPV lesions were present on the vulva. However, 14 women were asymptomatic. Thirty-nine women had atypical Pap smears. In half of these women, there was no evidence of intra-epithelial neoplasia. In 15 women with atypical Pap smears there was no clinical affection of the cervix uteri. But manifestations of wart virus infection in the vagina and/or vulva. Papillomavirus vulvovaginitis may be a subclinical infection, but many women suffer from distinct symptoms related to the location of the specific lesions. This infection of the vulva and vagina may be the sole cause of atypical Pap smears. The clinical recognition of this condition is a necessary prerequisite for a rational therapeutic approach.

Ketotifen in pollen-induced asthma: a double blind placebo-controlled study.

Twenty-nine children with an average age of 10.5 years were studied with respect to the protective effect of ketotifen on pollen-induced bronchial asthma. All of them were sensitive to deciduous tree pollen, the diagnosis being verified by bronchial challenge. The children were stratified in matched pairs and randomly allocated to two treatment groups, placebo or ketotifen 1 mg twice daily. The study was double-blind and was performed during the whole of the deciduous tree pollen season. Daily pollen counts were made, allergic symptoms were noted, additional medication was given and the expiratory pulmonary flow was recorded. During the birch pollen peak the ketotifen group showed significantly fewer, and less severe asthma and rhinoconjunctivitis than the placebo group. The anti-asthmatic medication was also used significantly less than in the placebo group. Ketotifen appeared to have good protective properties in the treatment of pollen-induced asthma and rhinoconjunctivitis.
