Surgical implications of pseudomonas aeruginosa necrotizing fasciitis in a child with acute lymphoblastic leukemia

Necrotizing fasciitis caused by Pseudomonas aeruginosa is extremely rare. Only 4 cases were reported in the literature. The authors report the occurrence of P aeruginosa necrotizing fasciitis starting out as a vulval abscess in a girl before induction chemotherapy for acute lymphoblastic leukemia. To our knowledge, this is the second case described in association with leukemia. In this case, the outcome was favorable because of early surgical intervention, confirming the diagnosis.

Efficacy of maintenance therapy with topical boric acid in comparison with oral itraconazole in the treatment of recurrent vulvovaginal candidiasis

OBJECTIVE

Our purpose was to examine the efficacy of a topical long-term treatment with boric acid versus an oral long-term treatment (itraconazole) in the cure and prevention of recurrent vulvovaginal candidiasis.

STUDY DESIGN

A prospective, nonrandomized study of patients affected by recurrent vulvovaginal candidiasis was undertaken. In 3 years we recruited 22 consecutive patients who underwent therapy with itraconazole (group 1) or boric acid (group 2). Women were followed up for 1 year, with clinic and microbiologic controls after 1, 3, 6, and 12 months after the first visit.

RESULTS

During the treatment, the positive culture results (15.1% vs 12.1%) and the signs and symptoms (33.3% vs. 24.2%) were similar within the 2 groups, with no significant statistical difference. With the withdrawal, after 6 months relapses were common in the 2 groups (54.5%).

CONCLUSIONS

Boric acid seems to be a valid and promising therapy both in the cure of the vaginal infection and in the prevention of relapses of recurrent vulvovaginal candidiasis, but its efficacy ends with the suspension of the therapy.

Pure versus complicated vulvar vestibulitis: a randomized trial of fluconazole treatment

OBJECTIVE

To examine the effectiveness of a 6-month treatment consisting of a weekly oral dose of 150 mg fluconazole for women with vestibulitis, and to explore the causes of treatment failure.

METHODS

Forty women with vestibulitis were randomized to either of two treatment groups. One group received a 6-month low oxalate diet with calcium citrate complement, as a placebo, and the second group the same diet and calcium citrate with the addition of a weekly oral tablet of 150 mg fluconazole. The women were examined 3 months after completing treatment, for response to therapy.

RESULTS

The addition of intensive 6-month fluconazole treatment did not lead to an outcome better than that attained by maintaining a low oxalate diet with calcium citrate supplementation. The satisfactory response rate was 15 and 30%, respectively. The presence of 'complicated vestibulitis', candidiasis concomitant with vestibulitis, decreases the satisfactory response rate regardless of the type of treatment administered (odds ratio 19.9, 95% CI 1.6, 250).

CONCLUSION

Prolonged oral fluconazole is an ineffective treatment of vestibulitis, whether pure or complicated by concomitant vulvovaginal candidiasis. The coexistence of candidiasis and vestibulitis - complicated vestibulitis - might represent a subset of vestibulitis that is resistant to the currently available medical therapy.

Trichophytic granuloma of the vulva

Fungal infections causing deep tissue involvement are known as trichophytic granulomas. We describe an unusual case of trichophytic granuloma presenting in the vulva of a 39-year-old woman.

Vulvar symptoms in paediatric and adolescent patients

Vulvovaginal symptoms in children and young adolescents are not yet very well understood, nor is the actual incidence known. This study evaluates the character and possible infectious aetiology of vulvar symptoms of females aged up to 16 y. The signs, symptoms and bacteriological findings of 68 consecutive cases were studied. The study was conducted in the University Hospital of Tampere at a special gynaecological consultation clinic for children and adolescents. Sixty-eight patients were included in the study: 48 girls (71%) were prepubertal, at Tanner stage M1P1, 26 patients were 2-4-y-old and 15 were 5-7-y-old. The duration of symptoms was known for 46 patients: 41% had had symptoms for >1 mo and 20% for >6 mo. Forty-eight patients had abnormal clinical findings on examination and 16 (33%) of them had an infectious aetiology. Streptococcus pyogenes infection was identified in 11 (16%) patients, all of whom had symptoms. Candida was identified in 6 (9%) patients. No infectious aetiology was found among 26 patients who had symptoms and abnormal clinical findings. Vulvovaginal symptoms during childhood are more common among younger children (<7 y). In 67% of patients no infectious aetiology could be found. Samples for microbiological culture should be taken from symptomatic patients and symptomatic areas. Cultures of Candida and bacteria are necessary but usually sufficient. If a microbiological aetiology is established, treatment can be assigned accordingly. Patients with vulvar symptoms and findings but with an unclear aetiology need support and advice on proper hygiene and can intermittently use mild corticosteroids locally.

An infective aetiology for vulval lichen sclerosus re-addressed

Although there is evidence to support an autoimmune basis for lichen sclerosus, there have also been some studies which suggest an infective aetiology. These include reports of the presence of spirochaetal forms with Steiner silver stains and purplish coccoid forms with Fite stains. We have repeated these studies on vulval biopsies obtained from 16 patients with vulval lichen sclerosus. Using the Steiner silver method we found no evidence of spirochaetal forms in any of the specimens. With the Fite stain we observed purple-staining coccoid forms within the dermis of 13 of the 16 lichen sclerosus specimens. However, these coccoid forms also stained strongly positive with toluidine blue, suggesting they were mast cell granules rather than micro-organisms. We were therefore unable to demonstrate evidence for an infective aetiology in vulval lichen sclerosus, although this cannot yet be excluded. Further work is also needed to understand the significance of mast cells in lichen sclerosus.

Effect of antibiotic use on the prevalence of symptomatic vulvovaginal candidiasis

OBJECTIVE

The purpose of the study was to evaluate the influence of antibiotic use on the prevalence of symptomatic vulvovaginal candidiasis.

STUDY DESIGN

This is a case-control study of 684 women with symptomatic vulvovaginal candidiasis who were enrolled at a vaginitis clinic and 901 control subjects who attended a cytologic screening service.

RESULTS

The prevalence of antibiotic use in the month preceding the visit was 19.3% (132/684) among patients with Candida infection compared with 11.9% (107/901) among control subjects (P <.001). After adjustment by logistic regression for potential confounders (age, marital status, and contraceptive method used), the odds ratio for vulvovaginal candidiasis among patients who reported antibiotic use in the month preceding the visit was 1. 75 (95% confidence interval 1.33 to 2.32). No differences in risk were found by type of antibiotic used. The likelihood of vulvovaginal candidiasis was directly related to the duration of antibiotic use and was higher in patients who had a history of repeated episodes of Candida vaginal infection.

CONCLUSIONS

Antibiotic use is a short-term risk factor for symptomatic vulvovaginal candidiasis, either as a first episode or in the form of recurrence. Increasing duration of antibiotic use is directly related with an increased prevalence of Candida vaginal infection.

Vulvodynia. Theory and management

Vulvodynia, defined as vulval pain, soreness or burning as opposed to itching or pruritus, is a common and important problem. Although not a sexually transmitted disease, it often presents to physicians working in that field. The main groups of vulvodynia are those where the symptoms are the consequence of an active dermatosis or infection, and those where it is not attributable to such conditions. In the latter group, the patients fall into two main categories: those of dysesthetic vulvidynia, with constant unprovoked pain, and vulval vestibulitis, with pain provoked by attempted vaginal entry. The recent realization that dysesthetic vulvodynia and vulval vestibulitis may be regarded as pain syndromes is proving a fruitful concept as regards both theory and management of these troublesome conditions.

Vulvar disorders in prepubertal girls. A literature review

OBJECTIVE

To review and discuss vulvar disorders in prepubertal girls.

STUDY DESIGN

Literature review.

RESULTS

Bacterial and fungal vulvitis, dermatitis, inflammatory dermatoses, secondary drug reactions, viral infections and a variety of vulvar tumors can all present as primary vulvar problems in prepubertal girls. In addition, systemic diseases can present with vulvar involvement.

CONCLUSION

In order to facilitate optimal care of prepubertal girls with vulvar disorders, a comprehensive review of the literature is presented.

Postpartum and vulvar necrotizing fasciitis. Early clinical diagnosis and histopathologic correlation

OBJECTIVE

To review the clinical course and correlate histopathologic findings of obstetrics and gynecology patients with necrotizing fasciitis

STUDY DESIGN

Seven-teen patients with postpartum or vulvar necrotizing fasciitis were identified from 1981 to 1996. Medical records were retrospectively reviewed. Information was available for all patients until death or discharge from the hospital. Histopathologic material on 15 patients was available for review.

RESULTS

Five postpartum patients were diagnosed and surgically debrided one to nine days after cesarean delivery, with no mortality. Twelve patients with vulvar necrotizing fasciitis were diagnosed and surgically debrided <1-10 days after presentation to a physician, with three deaths (25%). On histopathologic review, all cases had prominent lobular and septal panniculitis. Thirteen cases had histologic evidence of fasciitis.

CONCLUSION

Early diagnosis and aggressive surgical debridement in patients with postpartum and vulvar necrotizing fasciitis may improve the outcome. Histopathologic findings are remarkably consistent and may help to confirm the diagnosis.

Risk assessment, symptoms, and signs as predictors of vulvovaginal and cervical infections in an urban US STD clinic: implications for use of STD algorithms

OBJECTIVE

To identify clinical epidemiological correlates of cervical and vaginal infections and assess alternative algorithms, including two new reproductive tract infection (RTI) algorithms, for syndromic management of these infections.

DESIGN, SETTING AND SUBJECTS

We prospectively studied clinical manifestations and risk correlates of cervical and vaginal infections in a randomly sampled group of 779 female patients seeking evaluation for a new problem at a Seattle STD clinic.

METHODS

One experienced clinician performed standardised history, physical examination, and microscopy. Reference laboratories performed microbiological tests. Three levels of retrospective evaluation of algorithms included risk assessment and symptom review (RAS) alone; addition of speculum and bimanual examinations; and further addition of microscopy.

RESULTS

(1) Chief complaint of abnormal vaginal discharge predicted a significantly lower rate of gonorrhoea (GC) or chlamydial infection (CT) than rates observed with no complaint of vaginal discharge. Only the elicited symptom of yellow vaginal discharge (not the more common symptoms of increased or malodorous vaginal discharge) predicted GC or CT. Chief complaint of abnormal vaginal discharge itself predicted trichomoniasis (TV) and bacterial vaginosis (BV), not cervical infection. Candida albicans was strongly associated with the chief complaint of vulvar pruritus, not with the chief complaint of abnormal vaginal discharge. (2) Applying these algorithms in STD clinics only to women with the chief complaint of abnormal vaginal discharge, rather than to all women, decreases sensitivity for GC or CT, without increasing positive predictive value (PPV). Criteria for inclusion of patients have more effect on the performance of these algorithms than do the levels of evaluation used. (3) A modified World Health Organisation (WHO) algorithm applied only to patients with symptoms of vaginal discharge, involving treatment of RAS positives for cervical infection, followed by treatment of vaginal infections and cervicitis based on examination of RAS negatives and positives, had a sensitivity of 50% and PPV of 33% for cervical infection, and very low sensitivity for BV, TV, and for vulvovaginal candidiasis (VVC). (4) An RTI algorithm derived from these data, and applied to all STD patients, involving RAS and examination of all RAS negatives, provided treatment to all cases of BV and TV associated with symptoms of vaginal discharge; treatment of all VVC associated with symptoms of vulvar pruritus; treatment for GC and GT to all RAS positives (using easily elicited risk factors) and to RAS negatives with signs of cervicitis or PID. This algorithm had a sensitivity of 87% and a PPV of 33% for GC or CT in this population, with its 24% prevalence of GC or CT. The sensitivity for BV, TV, and VVC greatly exceeded that of the modified WHO algorithm. (5) A modified RTI algorithm, involving examination rather than treatment of RAS positive women, no examination of RAS negatives, decreased the sensitivity for cervical infection to 55% but increased the PPV to 51%.

CONCLUSIONS

Syndromic management of vaginal discharge offers relief of symptoms, prevention of transmission of trichomonas, and perhaps prevention of complications of BV. The 51% PPV of the modified RTI algorithm probably would warrant treatment and partner notification for GC and CT in settings with similar rates of GC and CT where more specific tests are lacking. However, as the prevalence of GC or CT decreases, the ratio of uninfected to infected who receive treatment with these algorithms would increase greatly, making the algorithms potential victims of their own success.

Disseminated Histoplasma capsulatum infection presenting as genital ulcerations

BACKGROUND

Histoplasma capsulatum infection in adults is most often subclinical but can result in disseminated disease with weight loss, fever, hepatosplenomegaly, and oropharyngeal ulcerations. Genital ulceration as the presenting sign of the disease has been reported rarely.

CASE

A 63-year-old woman presented with multiple vaginal ulcerations due to chronic disseminated H capsulatum infection. Initial diagnosis was made by Papanicolaou and Giemsa-stained vulvar smears. Ketoconazole therapy resulted in clearing of the lesions in 5 weeks.

CONCLUSION

Chronic disseminated histoplasmosis is an insidious and potentially fatal disease that can present rarely as genital mucocutaneous ulcerations in women. Prompt presumptive diagnosis can be accomplished by examination of smears obtained by ulcer abrasion, permitting institution of appropriate therapy.

Labial masses following vaginoplasty in male transsexuals: the differential diagnosis

Following vaginoplasty and vulvoplasty for male-to-female transsexualism, a mass may evolve in one of the major labia in a minority of patients. From April of 1989 to April of 1994, we treated seven patients with such masses. The case reports presented illustrate some of the differential diagnoses of this long-term complication. More often than not, the swelling was caused by infection. The funiculus or even testicular rest in itself also may represent the mass. Intralabial urethral fistula appears to be the second cause of swelling, either with or without inflammation. As an exceptional cause we observed a swelling representing a cyst of prostatic origin. In all, the mass could be excised completely.

Pasteurella multocida--an uncommon cause of obstetric and gynaecological sepsis

Pasteurella multocida is a common cause of wound infection following animal-inflicted wounds, but is a rare cause of female genito-urinary sepsis. We present a case of vulval sepsis and a case of intrapartum septicaemia with this bacterium. These two cases indicate that Pasteurella multocida can occasionally colonise the female lower genital tract and this bacterium should be considered in the differential diagnosis of serious infection related to this site.

Management of human papilloma virus vulvo-perineal infection with systemic beta-interferon and thymostimulin in HIV-positive patients

OBJECTIVES

To evaluate the effect of a combined therapy based on beta-interferon and thymostimulin in HIV-seropositive women with florid vulvoperineal condylomatosis.

METHODS

Nineteen HIV-seropositive women affected by HPV florid vulvo-perineal infection were studied. Their ages ranged from 19 to 32 years (mean = 26); all were smokers; 11 (57.89%) were intravenous drug users with a mean period of drug addiction of 5 years. No patient was on AZT therapy. All patients underwent a combined medical therapy based on beta-interferon administration with doses of 3,000,000 IU i.m. daily for 7 days and subsequently on alternate days for 2 weeks associated with the administration of 70 mg i.m. of thymostimulin per day on alternate days for 30 days.

RESULTS

Seven (36.84%) patients showed complete recovery at the end of follow-up; 5 (26.31%) patients showed partial recovery and 7 (36.84%) did not respond to therapy.

CONCLUSION

A pro-host immunotherapy seems to be indicated in patients affected by immunodeficiency syndrome.

Demonstration of Epstein-Barr virus DNA in acetowhite lesions of the vulva

Acetowhite lesions in the vulva disclosing koilocytosis have been related to infection by human papilloma virus (HPV). Because of the clinical resemblance of these lesions to oral hairy leukoplakia (OHL), and EBV-manifestation, 23 women with acetowhite koilocytotic lesions in the vulva were examined. The PCR-technique was used to detect EBV DNA as well as HPV DNA in 17% of 23 patients examined. In a control group of 19 patients EBV DNA was detected in 11% and HPV DNA in 42% of cell samples from normal vulvar mucosa. EBV DNA has not previously been demonstrated in the vulvar mucosa, and this virus might be related to subclinical acetowhite lesions.

Vaginismus: an important factor in the evaluation and management of vulvar vestibulitis syndrome

Dyspareunia is a common complaint in general gynecological practice. Many patients with dyspareunia suffer from vulvar vestibulitis syndrome (VVS). This syndrome constitutes severe pain on vestibular contact or attempted vaginal entry, tenderness to pressure within the vulvar vestibule and physical findings of vulvar erythema of various degrees. As a last resort, and only when all conservative treatments have failed, surgery is attempted. It has been our observation that a considerable percentage of patients with VVS present with concomitant vaginismus. Furthermore, surgery is less successful in this subgroup of patients unless the vaginismus is first treated. This report describes the evaluation and treatment of 14 patients with VVS.

Multicentric papillomavirus infection of the female genital tract. A study of morphologic pattern, possible risk factors and viral prevalence

We have investigated 103 biopsy specimens obtained from 50 women (average 28.1 years, range 16-66) with multicentric condylomatosis of the genital tract, including the uterine cervix (48 samples), the vagina (23), and the vulva (32). Each patient had at least 2 biopsies. A positive in situ hybridization for a Human Papilloma Virus (HPV) cocktail was observed in samples from 38 patients: in these multiplicity of lesions regarded the cervix and vulva (22 cases), cervix and vagina (12), vulva and vagina (1), cervix, vulva and vagina (3). Viral types 6,11 were more prevalent in simple condylomata. Both low- and high grade lesions of cervix, vagina, and vulva showed prevalence of types 16, 18 and 31, 33, 35. Signaling for more than one probe cocktail was detected in 14 (13.6%) samples. Partner's condylomatosis was referred to by a sizeable minority of patients. It is concluded that the spectrum of HPV infection in the female genital tract reflects a multiplicity of factors, including involved viral type and site, immunitary reaction of the host, perpetration or reactivation of latent infections.

[Kerion of the vulva. Report of a case and review of the literature]

We report a case of a 43 year old woman who developed an extensive vulvar kerion caused by Trichophyton menthagrophytes that was initially mistaken for a bacterial infection. The peculiarity of this case lies in the fact that the kerion is rarely located in the vulva and it has not yet been described in the literature. On the contrary, cases have been found in the scalp, beard, eye-brow, etc. We discuss the etiopathogenetic aspects, criteria for differential diagnosis and therapy management of this rare clinical picture.

Evaluation of a monoclonal antibody-based enzyme immunoassay for early detection of herpes simplex virus genital infection

A monoclonal antibody-based enzyme immunoassay test for detection of herpes simplex virus (HSV) type-common antigen was evaluated in 40 women with vulvar lesion suspicious for genital HSV infection. The assay gave interpretable readings in 90% of the cases, with sensitivity and specificity of 100% and 92% respectively, a negative predictive value of 100%, and a positive predictive value of 75%. With a few limitations, the assay may be used for early diagnosis of genital HSV infection.

[Condyloma acuminatum: histopathology and detection of human papilloma virus]

Comparing with the results of HPV DNA detection by PCR, 44 cases of condyloma acuminatum and condyloma-like lesions in female genital tract were studied histopathologically. Among 40 cases formerly diagnosed as condyloma acuminatum or suspicious condyloma acuminatum, all were HPV DNA detectable. HPV6 and HPV11 were found in 4 cases without koilocytes. HPV6 was found in one out of 4 cases formerly diagnosed as pseudocondyloma. The result showed that koilocytes are characteristic and diagnostic, anyhow, undiscovery of these cells still cannot rule out the possibility of condyloma acuminatum.

Nonfluorescent erythrasma of the vulva

BACKGROUND

Erythrasma is an uncommon vulvar infection, best diagnosed by its fluorescence under the Wood lamp. This report shows that despite a negative Wood lamp examination, the diagnosis can be made histologically.

CASE

A 42-year-old woman was referred to our clinic with a persistent candidal infection. Evaluation included a Wood lamp examination, wet mount, and potassium hydroxide test of the affected skin, all of which were negative. A biopsy of the area demonstrated rods and filamentous organisms in the keratotic layer consistent with a Corynebacterium minutissimum infection. The patient was diagnosed as having erythrasma, and she responded to oral erythromycin.

CONCLUSION

Persistent vulvar diseases may be caused by erythrasma despite a negative Wood lamp examination. The diagnosis can be made by biopsy of the lesion.

[Colposcopical and pathological study of vulvar pseudocondyloma]

One hundred and forty seven cases of pseudocondyloma, which were diagnosed by colposcopy and histopathology, and 129 cases of condyloma as control group were studied. Pseudocondyloma showed colposcopically as crowded together distribution of single papilla or vesiculated papules without branching structure and capillary loops. The color of the lesions is unchanged after acetic acid stain. The lesions can be divided into vesicular proliferative type and ciliary proliferative type. Differing from condyloma, pseudocondyloma lesions showed histopathologically only slight proliferation of squamous epithelium, lack of diagnostic koilocytes and negative result in HPV immunohistochemical study and hybridization of HPV-DNA. It is a reliable method to make a diagnosis of pseudocondyloma by colposcopy and histopathology.

[Clobetasol vs. testosterone in the treatment of lichen sclerosus of the vulvar region]

The paper describes a study carried out in 40 patients affected by lichen sclerosus (LS) of the vulva. The mean age of patients was 60.9 years (range 27-83) and 31 were in menopause. Patients were divided randomly into two groups of 20. The symptoms (itching, burning, pain, dyspareunia), clinical aspects (atrophy, hyperkeratosis, sclerosis) and histological alterations (atrophy of the epithelium, edema, inflammatory infiltrate, fibrosis) were quantified in each patient by a score. The mean scores relating to the three parameters examined were then calculated for each group. One group was treated with testosterone propionate 2% and the other with a strong synthetic corticosteroid, clobetasol dipropionate 0.05%. After 24 weeks of treatment patients were again evaluated in relation to clinical (symptoms and clinical aspects) and histological parameters, following the procedure used before the start of treatment. The mean scores obtained were then compared with those before the start of treatment. Statistical analyses were performed using Student's t-test. Testosterone was found to be effective in relation to symptoms but no significant change was observed in relation to clinical aspects and histological alterations. It also caused major secondary effects which led to the suspension of treatment in one patient. Clobetasol was shown to be highly effective both in relation to symptoms and in terms of clinical aspects and histological alterations, and did not cause any noteworthy collateral effects, especially contact dermatitis. In the context of the objective parameters examined in this study, sclerosis and hyperkeratosis were easily modified by corticosteroid treatment in comparison to atrophy, especially in those patients with a longer duration of disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Enhanced tenascin expression in cervical and vulvar koilocytotic lesions

Tenascin is an extracellular matrix glycoprotein that is widely expressed during embryogenesis. In adults, it is restricted to select sites, including certain epithelial-stromal interfaces, but is notably enhanced in active inflammatory-reactive processes and in the stroma of many neoplasms. The authors immunostained with the monoclonal antibody (MAb) 100EB2 cryosections of vulvar and cervical biopsies displaying convincing koilocytosis with variable degrees of hyperplasia-dysplasia; in situ carcinomas were included. The presence of human papillomaviruses (HPV) 6, 11, 16, 18, 31, or 33 was confirmed by in situ hybridization in a subset of cases. Findings were compared with normal controls. The study was extended with the MAb 143DB7 that reacted with tenascin in paraffin sections. In normal samples, tenascin immunoreaction appeared as a delicate, continuous rim, in the immediate vicinity of the laminin staining; in parakeratotic areas, the rim was thicker. In foci of hyperplastic-dysplastic epithelium with or without koilocytosis, a distinct increase in tenascin staining was noted; enhanced tenascin often paralleled increasing hyperplasia and dysplasia. In most cervical and vulvar carcinomas in situ, the reactions were intense and extended deeply and raggedly into the underlying stroma. Tenascin was selectively enhanced in the endocervical stroma around inflammed or metaplastic glands. The authors conclude that tenascin is increased in HPV infection associated with epithelial proliferation. Enhancement was most consistently strong and extensive in in situ carcinomas, suggesting a correlation with active phases of epithelial growth and stromal remodeling.

Granuloma inguinale: three cases diagnosed in Toronto, Canada

Granuloma inguinale (GI) is a sexually transmitted disease seldom seen in the United States and Canada. We are reporting three cases recently seen in Toronto, Ontario, two in immigrants, and one in a native born Canadian who had an intimate relationship with a foreign visitor. The basic features of the disease are discussed.

Vulvar manifestations of human papillomavirus infection

As technology continues to improve, we are increasingly able to detect the presence of HPV in both clinically diseased and histologically and clinically normal vulvar tissue. Unfortunately, the technology for effective treatment of these conditions has not advanced as rapidly. Still, fundamental information about the interaction of HPV with the host cell continues to be collected and will provide us with an increased understanding of the importance of latent infection and its progression to clinical vulvar disease. There are a host of therapeutic modalities available for the treatment of HPV-associated conditions of the vulva, ranging from simple topical medication like podophyllin to sophisticated combination therapies involving carbon dioxide laser destruction in conjunction with interferon. Regrettably, there is no "magic bullet" that is totally effective for any of the HPV-associated vulvar diseases. This makes it more important to weigh the benefits and morbidity of treatment regimens before they are used. Until the success rate of available therapies improves, it is important to have definitive goals for therapy, because it is currently impossible to completely eradicate HPV from tissues. Examples of therapeutic goals might range from removal of visible lesions or treatment of symptomatic areas to treatment of premalignant or malignant lesions. At present, perhaps the most important service we can provide for patients is close follow-up of HPV-associated vulvar diseases in an attempt to prevent the development of invasive malignancy. Regardless of the choice of treatment, the primary objective of the clinician should be to help the patient but to do no harm.

Prevalence, diagnosis and treatment of lower genital neoplasia in women with human immunodeficiency virus infection

The prevalence of lower genital neoplasia and Human Papilloma-virus-related genital lesions were evaluated in a cohort of 75 women with Human Immunodeficiency Virus type 1 (HIV-1) infection at different stages of HIV disease. The overall rate of cervical intraepithelial neoplasia (CIN) in the group studied was 29.3% (22/75). Eight out of 10 high-grade CIN lesions contained 'high-risk' HPV-DNA 16/18 and/or 31/35/51 as demonstrated by 'in situ' hybridization with biotinylated probes. Vulvar and/or perianal condylomata were histologically diagnosed in 14 patients (18.7%); nine of these biopsies contained detectable HPV-DNA which was always related to HPV 6/11. The rate of high-grade CIN in symptomatic HIV-infected patients was 28% (7/25) as compared to 6% (3/50) of the other cases (P = 0.022). CD4 lymphocyte counts, white blood cell counts, CD4+/CD8+ cell ratio and percentage of CD4+ lymphocytes were lower in patients with high-grade CIN in comparison to the patients with negative colposcopical and/or cytological examination. After adequate standard treatment (cryotherapy, electrocauterization, cold-knife conization) only one case of CIN 2 recurred during the 2 years of follow-up period. The prevalence of lower genital neoplasia and HPV-related lesions among HIV-infected women is high and seems to correlate with the severity of HIV disease.

[Haemophilus influenzae and genital infection]

We report nine cases of H. influenzae genital infections in women. Six patients had a total of 7 episodes of Bartholin glands abscess. One patient developed a post-caesarean endomyometritis on the 16th post-delivery day. The remaining patient developed an amniotic fluid infection in the 32nd week of pregnancy. All the nine H. influenzae strains were sensitive to ampicillin. We assess the rising importance of H. influenzae as an etiologic agent of female genital tract infections.

Human papillomavirus infection in vulvar lesions of lichen sclerosus et atrophicus

Human papillomaviruses (HPV) types 6, 11, 16 and 18 infections were investigated in 18 vulvar lesions of lichen sclerosus et atrophicus (LSA) using in situ DNA hybridization and polymerase chain reaction (PCR) on formalin-fixed paraffin-embedded specimens. Four out of 18 specimens were found to be infected with HPV type 16 using the PCR technique. Interestingly, three of these four patients were in a premenopausal state. This difference proved to be the only distinguishing feature in a comparison of HPV type 16-infected patients with non-infected patients. In situ hybridization revealed no positive result in any case and PCR demonstrated no HPV-DNA type 6, 11 or 18. Patients with HPV type 16-infected lesions may be regarded as at risk of developing vulvar cancer. Therefore, long-term follow-up of this subgroup is particularly important.

Is vestibular papillomatosis associated with human papillomavirus?

The origin and clinical significance of vestibular papillae were evaluated by comparing histological features with the presence of human papillomavirus (HPV) types 6/11 and 16/18, as revealed by Southern blot DNA hybridization. Twenty women with vestibular papillomatosis underwent clinical evaluation and follow-up. When available, male partners were also examined. Histological changes suggestive of HPV infection were present in all the 20 specimens. Sixteen cases (80%) contained DNA sequences homologous to the viral probes. In particular, 12 cases (60%) reacted with the HPV 16/18 probe. Follow-up for more than 18 months revealed no variation in the distribution and appearance of vestibular papillae. No male partner showed signs of HPV lesions. The study shows that HPV 16 is frequently associated with vestibular papillae but does not support a productive infection. Therefore the most appropriate management of these patients should be evaluated clinically in each individual case.

Subclinical vulvar papillomavirus infection

Eighty-eight cases of subclinical human papillomavirus (HPV) vulvar infection were detected in a consecutive colposcopic series of 968 women. Three patterns of acetowhite lesions had a 72% predictive value (88/122) for histologically assessed HPV. The prevalence of subclinical vulvar HPV in self-referred patients was 7.9% (73/918); it was 9% (88/968) in the overall series and significantly higher in younger patients (age less than 25 years: 21/106, or 19.8%) or in those with cervical HPV or cervical intraepithelial neoplasia (CIN) (40/100, or 40%). Routine inspection of the vulva after acetic acid lavage in association with a Papanicolaou test might help identify Papanicolaou-test-negative patients at high risk of developing cervical HPV or CIN. Treatment with beta-interferon (2,000,000 IU daily intramuscularly for 10 days) was given to 30 consecutive patients, but the results were poor: regression was observed in only 2 cases.

Occurrence of multiple types of human papillomavirus in genital tract lesions. Analysis by in situ hybridization and the polymerase chain reaction

More than 22 types of human papillomavirus (HPV) have been detected in genital tract squamous cell intraepithelial lesions. Seven of two hundred eighty-six (2.4%) genital tract tissues in which HPV DNA was detected by in situ hybridization contained two or more different HPV types. When analyzed by site, 5 of 204 (2.4%) of cervical intraepithelial lesions were infected by more than one type, compared with 2 of 82 (2.4%) of vulvar lesions. The rate for low-grade lesions was similar (5/218; 2.3%) to that for high-grade lesions (2/68; 2.9%). In contrast, two different HPV types were detected in 6/33 (18%) of tissues by the polymerase chain reaction (PCR) using type-specific primers for eight HPV types. It is concluded that infection by one HPV type is rarely associated with concurrent 'active' infection by a second HPV type, even though DNA of a different viral type can be detected by PCR in about one fifth of such cases. Further study is required to determine if an existing HPV infection can inhibit replication by a different HPV type.

[Vulvar pruriginous squamous papillomatosis]

Pruritic vulvar squamous papillomatosis (PVSP) is a recently described clinical entity whose aetiologic agent has been reported to be the human papilloma virus. We have seen 9 patients with PVSP. We believe that our clinical and histological data, along with the results of the in situ hybridizations stress out the evidence of a viral aetiology in the PVSP.

Human papillomavirus coinfections of the vulva and uterine cervix

DNA filter in situ hybridisation (FISH) was used to determine the presence of human papillomavirus (HPV) genotypes 6/11, 16/18, and 31/33 in cell scrapes of the cervix and vulva of 128 women who had precancerous lesions and/or HPV infection of the cervix diagnosed by cytology, colposcopy, and histology. HPV-DNA was found in 87 (68%) vulval and 95 (74%) cervical cell scrapes, and in both the vulval and cervical scrapes of 73 (57%) women, but not in either the vulva or the cervix of 19 women (15%). Of the HPV-DNA-positive smears, the prevalence of the HPV types was 61% HPV 16/18, 14% HPV 6/11, 3% HPV 31/33, and 22% HPV 6/11 and 16/18. By contrast, HPV-DNA was not detected in the cervical smears of a control group of 35 women who were assessed to be free of cervical abnormalities by colposcopy and cytology. The epithelial response of the vulva and the cervix to application of 5% acetic acid was assessed by colposcopy and the results correlated with the presence of HPV genotypes. A possible or definite disorder of the cervix and vulva was detected by colposcopy in 95 (74%) and 96 (75%) of the 128 cases, respectively. The colposcopic assessment of the vulva was inconclusive in ten cases (8%), and only eight women (6%) were found to be free of both a vulval and cervical disorder. This study shows subclinical papillomavirus infections of the vulva frequently coexist with HPV infections and precancerous lesions of the cervix.(ABSTRACT TRUNCATED AT 250 WORDS)
