O tratamento radical inclui o esvaziamento inguinal bilateral na maioria dos casos. Aproximadamente 30% das pacientes operáveis têm disseminação linfonodal, as 70% restantes têm mutilação desnecessária. A possibilidade de aplicar o conceito de linfonodo sentinela, na conservação dos linfonodos regionais da vulva, ainda não é consenso. O modelo experimental na vulva da cadela é um passo importante no reconhecimento das peculiaridades da drenagem linfática deste órgão pela similaridade com a drenagem em humanos. Este trabalho experimental, em modelo canino tem como objetivo apresentar o modelo para a pesquisa do linfonodo sentinela na vulva da cadela usando o Azul Patente e Fitato de Tecnécio; avaliar o Azul Patente como marcador do linfonodo sentinela da vulva da cadela; avaliar o Fitato de Tecnécio como marcador do linfonodo sentinela na vulva da cadela, comparar os métodos obtidos pelas duas técnicas. Foram utilizados nos procedimentos 25 cadelas, adultas, sadias, com peso variando entre 10 e 12kg. Injeção de 5µCI de Tecnécio na região vulvar, com espera de 30’. Rastreamento com probe das regiões de drenagem vulvar, injeção de 0,5mL de azul patente na região vulvar, com espera de 15’. Definidos os pontos “quentes” com o probe, por incisões inguinais abordou-se o linfonodo, avaliando-se com o probe o linfonodo sentinela in-vivo e ex-vivo, anotando-se os valores; registrados os linfonodos corados e não corados com azul patente; comparados os dois métodos. Em 88% dos linfonodos houve presença da lateralidade, tal diferença foi significante (² = 28.88 e p<0,0001). Não houve diferença significante (p>0,05) entre os lados direito e esquerdo, quanto à intercessão dos dois métodos. Os níveis de radiação detectados foram idênticos em ambos os lados (p>0,05), também não foi verificada diferença significante (p>0,05) em ambos os lados, nas contagens in vivo e ex vivo, e no número de linfonodo corado com azul patente. O modelo experimental apresentado foi capaz de definir o linfonodo sentinela utilizando o Azul Patente e Tecnécio(99mTc). A identificação do linfonodo sentinela é exequível com Azul Patente no mapeamento da cadeia linfática; o mapeamento linfático com Tecnécio(99mTc), permite identificar com detalhes o sistema de drenagem linfática; não houve diferença significante entre os dois métodos (p=1,0), Azul Patente e Tecnécio(99mTc).

Radiotherapy in the management of carcinoma of the vulva in HIV positive and negative patients : an institutional experience

Opakas, Jesse Elungat 04 1900 (has links)
Thesis (MMed)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Radiotherapy in the Management of Carcinoma of the Vulva in Human Immune-Deficiency Virus (HIV) Positive and Negative Patients: An Institutional Experience. Opakas J. Department of Medical Imaging and Clinical Oncology, Division of Radiation and Clinical Oncology, Tygerberg Academic Hospital and the University of Stellenbosch Background: Radiotherapy and chemotherapy are integral parts of the effective and optimal management of patients with vulva cancer, especially when initiated early in the course of this disease. Often, surgical resection alone cannot effect total removal of the tumour or may not be feasible. Human Immune-Deficiency Virus (HIV) infection has been an epidemic in sub-Saharan Africa. Highly Active Antiretroviral Therapy (HAART) is available in public health facilities in the region to arrest and control HIV infection, delaying the progression to AIDS and death. Infection with HIV has now been transformed into a manageable, chronic disease and this has allowed patients to live longer, healthier and more productive lives. Human Immune-Deficiency Virus (HIV) infection may further complicate the management of vulva cancer disease as patients are immunocompromised and may have difficulty in completing treatments prescribed. This study aims to identify and assess the outcomes, tolerances, toxicities and factors influencing treatment completion in both HIV positive and negative patients with vulva cancer treated at Tygerberg Academic Hospital. Study Design and Methods: This is a retrospective, observational, cross-sectional review of the factors influencing the completion of radical radiotherapy in the treatment of locally advanced cancer of the vulva. Patients are classified as either HIV positive or HIV negative. The period of the study was between 1st. January 2007 and 31st December 2012 and it was conducted at the Division of Radiation Oncology, Tygerberg Academic Hospital, Cape Town, South Africa. All the HIV positive patients were already on antiretroviral therapy at the outset. The disease and treatment characteristics are described as well as toxicities of treatment of patients undergoing radiotherapy and chemo-radiation. Treatment completion for the two groups is evaluated. The toxicities that led to treatment interruptions for these groups are also listed. Results: Of the 68 patients screened, 25 met inclusion criteria; of these patients, seven (28%) were HIV positive while the other 18 (72%) were negative. Vulva cancer patients infected with HIV presented at a younger age and with more locally advanced tumours compared to HIV negative patients. There is no statistically significant difference between the two groups in treatment completion rates and tumour failure rates. Conclusion: This retrospective study concludes that HIV positive patients with vulva cancer presented with a more locally advanced disease and at a younger age when compared to HIV negative patients. There was no statistically significant difference in overall therapeutic outcomes although cutaneous toxicities were more pronounced in the HIV positive subset. Chemo-radiotherapy sequentially or concurrently can be regarded as a standard of care in both HIV positive and negative patients provided that the HIV patients are on antiretroviral therapy. / AFRIKAANSE OPSOMMING: Nie beskikbaar

It affects primarily elderly women, and has been more frequent in young patients associated with HPV infection. With the aim to identify pertaining factors evaluated in the genesis and progression of this tumor, an evaluation was carried out by immunohistochemistry (StrepABC), to identify the presence of estrogen and progesterone receptor in the epithelia and stroma of 45 vulvar lesions, of which 22 are invasive squamous cell carcinomas (ISCC), 12 are high-grade intraepithelial lesions (HSIL) and 11 are low-grade intraepithelial lesions (LSIL). Furthermore p53 protein expression and the cell proliferating index, through MIB1, were evaluated. The cases came from the Cancer Institute of Ceará (CIC), the Hamilton Monteiro Laboratory of Pathology (HML) and the Laboratory of Pathology of UFC. A descriptive analysis of the parameters and their correlations were carried out with a statistical significance level of at least 95% (p ≤ 0,05). Results and inferences: 1 - Age: The ISCC occurred between the ages of 34 and 76 years (average 58.59 and median 60.5), the HSIL ranges from 18 to 59 years (average 40,91 and median 42) and the LSIL-papilloma within the ages of 18-58 (average 32.63 and median 32), in the expected age groups and interval ranges, according to the natural history reports of such lesions, highlighting the growing of ISCC in patients ever younger. 2 - Hormonal receptor: The nuclear receptors of estrogen and progesterone were detected in the three groups analyzed, with a growing tendency of tumoral progression, however without significant statistical correlation in the epithelia level. Thus they cannot be considered a predictive and prognostic factor in the follow-up of these lesions. However in the stroma the presence of nuclear immunostain is significant (more with ER) in the HSIL and ISCC, which can be important to the tumor growth. The high and frequent immunostain was also observed in the cytoplasm of keratinocytes of in situ carcinomas and keratinizing invasive squamous cell carcinoma. These findings will be evaluated in the future. 3 - p53: The expression of p53 was detected in all groups, ISCC (68,18%), HSIL (66,66%) and LSIL (63,63%), having more frequent high scores in carcinomas (53,33%) than in LSIL (0,00%). The behavior of HSIL is similar to the behavior of ISCC. It is evident that there is an accumulation alteration of p53 with the tumoral progression. 4 - MIB1- There were significant differences between ISCC and LSIL (p=0,00), also among HSIL and LSIL (p=0,03). There was no significant difference between ISCC and HSIL. This expresses the tendency of high index cell proliferation with tumoral progression. In addition, the independence of the variables, MIB1 and p53, were verified. / O câncer de vulva, embora entidade rara, envolve problemas sérios de tratamento devido à extensão cirúrgica e conseqüente mutilação. É uma neoplasia que acomete preferencialmente mulheres em idade mais avançada, tendo havido uma crescente incidência em pacientes de menor faixa etária com infecção pelo HPV. Com o objetivo de identificar fatores envolvidos na gênese e na progressão dessas neoplasias, foi avaliada, por imunoistoquímica (StrepABC), a presença de receptores hormonais de estrógeno e de progesterona no epitélio e estroma de 45 lesões vulvares, sendo 22 carcinomas epidermóides invasores (CEC), 12 lesões intra-epiteliais escamosas de alto grau (LIEAG) e 11 lesões intra-epiteliais escamosas de baixo grau (LIEBG); também, a expressão da proteína p53 e o índice de proliferação celular, mediante o MIB1, conforme a idade. Os casos foram oriundos do Instituto de Prevenção do Câncer do Ceará (IPCC), do Laboratório de Patologia Dr. Hamilton Monteiro (LHM) e do Laboratório de Patologia da UFC. Procedeu-se à análise descritiva dos parâmetros e de suas correlações, com nível de significância de pelo menos 95% (p≤0,05). Resultados e inferências: 1- idade: os CEC incidiram dos 34 aos 76 anos de idade (média aos 58,59 anos e mediana aos 60,5 anos); as LIEAG ocorreram dos 18 aos 59 anos (média aos 40,91 anos e mediana aos 42 anos) e as LIEBG, dos 18 aos 58 anos (média aos 32,63 anos e mediana aos 32 anos), dentro das faixas e intervalos etários esperados conforme relatos da história natural de tais lesões, destacando-se a ocorrência crescente de CEC em pacientes de faixa etária cada vez menor; 2- receptores hormonais: os receptores nucleares de estrógeno e de progesterona estão presentes nos três grupos analisados, com tendência crescente com a progressão tumoral; todavia, sem correlação estatisticamente significativa ao nível do epitélio, não podendo ser considerados como marcadores preditivos / prognósticos no seguimento dessas lesões. Entretanto, no estroma, é significativa a presença maior de núcleos marcados (mais com RE) nas LIEAG e nos CEC, o que pode ter importância no crescimento tumoral. Viu-se, ainda, marcação citoplasmática forte e freqüente para progesterona em lesões escamosas in situ e invasoras ceratinizantes, devendo esses achados serem mais bem avaliados em pesquisas subseqüentes; 3- p53: houve expressão de p53 em todos os grupos, CEC (68,18%), LIEAG (66,66%) e LIEBG (63,63%), sendo significativa a preponderância de escores altos nos carcinomas (53,33%) em relação às LIEBG (0,00%). O comportamento das LIEAG em relação à p53 é similar ao comportamento dos CEC; fica patente que há alteração acumulada da p53 com a progressão tumoral; 4- MIB1: houve diferença significativa dos núcleos marcados para MIB1 entre os CEC e as LIEBG (p=0,00), assim como entre as LIEAG e as LIEBG (p=0,03). Não houve diferença significativa entre os CEC e as LIEAG. Isso expressa uma tendência ao maior índice de proliferação celular com a progressão tumoral. Verificou-se ainda a independência das variáveis p53 e MIB1.

Tivemos como objetivo avaliar a presença do HPV e da proteína p53 e correlaciona-Ias com outros parâmetros clínico-patológicos nos grupos de pacientes com neoplasia intraepitelial vulvar (NN m - 38 casos), carcinoma superficialmente invasivo (nove casos) e carcinoma escamoso invasivo da vulva (55 casos). A detecção do HPV foi realizada através de exame imuno-histoquímico com o anticorpo anti-HPV policlonal e da hibridização molecular in situ com sondas biotiniladas de amplo espectro e para os tipos 6/11, 16/18 e 31/35/51. A proteína p53 foi identificada através de exame imuno-histoquímico com o anticorpo monoclonal DO-7. No grupo com NN m a idade média das pacientes foi de 47,5 anos; 45,7% tinham lesão de condiloma associado, o HPV estava presente em 57,9% dos casos e a proteína p53 em 21,1%. As pacientes com carcinoma superficialmente invasivo tinham idade média de 57,9 anos, lesão de condiloma em 22,2%, detecção do HPV em 33,3% e da proteína p53 em 66,7% dos casos. No carcinoma escamoso invasivo a idade média foi de 67,8 anos e apenas 7,3% das pacientes tinham lesão de condiloma associado; lesões distróficas estavam presentes em 60% dos casos e NN m em 25,5%; o HPV foi identificado em 7,3% e a proteína p53 em 58,2%. A detecção do HPV foi mais freqüente no grupo com lesão de NN m e estava relacionada à idade mais jovem das pacientes. No grupo com carcinoma invasivo, a variante histológica mais freqüente foi a queratinizante usual e estava associada à presença de lesões distróficas e da proteína p53. Entretanto, uma pequena subpopulação de pacientes mais jovens continham a variante basalóide do carcinoma invasivo, freqüentemente associada à lesão de NN m e à infecção pelo HPV. Os nossos resultados são semelhantes aos da literatura, onde um grupo de lesões está relacionado com a infecção pelo HPV e outro não. O HPV 16/18 foi o tipo predominanteem todos os grupos de lesões. Índices mais baixos de detecção da p53 nas lesões de NN m e maiores e com proporções semelhantes no carcinoma superficialmente invasivo e invasivo, além da ausência de relação entre a presença da p53 e do HPV, indicam que a imunodetecção da p53 é secundária à invasão do estroma pela neoplasia e é independente da presença de infecção viral. A detecção da proteína p53 estava associada apenas com a profundidade de invasão tumoral e não mostrou relação com neoplasia recidivante ou metástases ganglionares e, portanto, não tem valor como marcador para lesões recidivantes ou metastáticas, pelo menos para o grupo de pacientes incluídas neste trabalho / Abstract: Vulvar squamous cell carcinoma still is a disease of unknown etiology. Recent studies have pointed out to a multifactorial origin, with HPV as the causal agent in the developrnentof vulvar neoplasia in younger age groups, whereas in older patients it would be possibly related to dystrophic lesions,genetic mutations, and other factors still unknown. Our purpose was to analyze the presence of HPV and p53 overexpression and correlate them with other clinical and pathological parameters in patients with vulvar intraepithelial neoplasia grade m (VIN m - 38 cases), superficially invasive carcinoma (nine cases), and invasive squamous cell carcinoma of the vulva (55 cases). HPV infection was determined by immunoperoxidase reaction with a policlonal antibody against HPV and by in situ hybridization with biotinilated probes for wide spectrum and HPV types 6/11, 16/18 and 31/35/51. P53 overexpression was detected by immunoperoxidasereaction with the monoclonal antibody DO-7. In the VIN m group, the mean age was 47.5 years; 45.7% had associated condylomatous lesions, HPV infection was detected in 57.9% ofthe cases, and p53 overexpression in 21.1%. The patients with superficially invasive carcinoma had mean age of 57.9 years, condylomatous lesions in 22.2%, HPV infection in 33.3%, and p53 overexpression in 66.7% ofthe cases. In the invasive squamous carcinoma group the mean age was 67.8 years; 7.3% ofthe patients had associated condylornatous lesions, 60% presented with dystrophic lesions and 25.5% with VIN m; HPV were identified in 7.3%, and p53 overexpression in 58.2% of the cases. Our findings revealed that HPV detection occurred mainly in the VIN m group and was related to younger patients. In the invasive squamous carcinoma group, the most common histological variant was the usual type of keratinizing squamous cell carcinoma, and it was associated to dystrophic lesions and p53 overexpression. However, a small subpopulation of younger patients contained the basaloid type of invasive carcinoma, and it was :&equentlyassociated to VIN m lesions and HPV infection. Our results are similar to other reports, where two separate entities of the disease exist, one associated with HPV infection, and other unrelated to it. HPV 16/18 was the predominant type in all the three groups of lesions. The weakness or absence of p53 overexpression in VIN m lesions, and its higher detection, with stronger positivity and similar distribution in superficially invasive and invasive carcinoma, together with the lack of relationship between p53 overexpression and HPV infection, indicates that p53 overexpression is related to neoplastic stromal invasion and it is independent of HPV infection. P53 detection was associated only to the depth of stromal invasion and unrelated to tumor recurrence or lymph node metastasis and therefore, it had no significance as a prognostic marker, at least in the group of patients included in this study / Doutorado / Anatomia Patologica / Doutor em Ciências Médicas

A fim de estudar possíveis fatores, incluindo as vulvovaginites, que pudessem estar associados à ocorrência das diferentes formas de lesões genitais determinadas pelo HPV, foram analisados os dados de 290 mulheres com diagnóstico histológico desta doença e que apresentaram exclusivamente lesões clínicas (206 casos) ou subclínicas (84 casos) que freqüentavam o Ambulatório de Infecções Genitais do Departamento de Tocoginecologia da Universidade Estadual de Campinas. Foi realizado estudo de corte transversal, retrospectivo e observacional, para identificação de quais das seguintes variáveis: idade, união conjugal, escolaridade, cor de pele, número de gestações, partos e abortos anteriores, métodos anticonceptivos, número de parceiros, início da atividade sexual e freqüência de relações sexuais semanais pudessem estar associadas à forma clínica ou subclínica da doença, bem como, verificar a prevalência das vulvovaginites, isoladas ou não, e suas associações com as formas de lesão determinadas pelo HPV. Identificaram-se, também as alterações da flora vaginal e suas possíveis associações ao condiloma acuminado (HPV-clínico) ou lesão plana (HPV-subclínico). Tanto a análise bivariada, quanto a multivariada mostraram que as vulvovaginites não se associaram diferentemente às formas clínica e subclínica da infecção genital feminina pelo HPV. Mesmo assim, ficou claro a alta freqüência em que estas ocorrem na presença da lesão determinada pelo Papilomavírus humano (clínico 50,5% e subclínico 54,8%). Por outro lado, a análise estatística bivariada apontou a lesão subclínica mais freqüentemente associada à união conjugal não estável, uso de anticonceptivo hormonal injetável trimestral e finalização de partos anteriores (via vaginal). A análise múltipla com regressão identificou, ainda, que a menor idade, a união conjugal não estável, escolaridade superior e gestações anteriores, associaram-se significativamente às infecções na forma subclínica. A ausência de gestação anterior e finalização de parto anterior via alta (cesárea), associaram-se à forma clínica da infecção. Em nenhuma das análises pôde-se observar influências marcantes do comportamento sexual na expressão das lesões genitais HPV induzidas. Concluiu-se que, paralelamente aos tipos virais do HPV infectantes da genitália feminina, outros fatores estão associados aos diferentes tipos de expressão clínica da doença / Abstract: The causes which lead a patient to manifest different forms of HPV genital infection, are still not clear. To be able to identify possible factors, including vulvovaginitis, which could influence the manifestation of lesions caused by different types of HPV, 290 women with a histological/cytological diagnosis and presenting clínical (206 cases) or subclinical lesions (84 cases), were analysed. This was a retrospective, observational transversal cut study to identify the following variables: age, marital status, schooling, race, number of gestations, previous deliveries and miscarriages, contraceptive methods; number of sexual partners; freqüency of intercourse per week and age of first sexual experience, which could be associated to the type of lesion caused by HPV, as well as to verify the prevalence of vulvovaginitis and its association to lesions determined by HPV. Vulvovaginitis infections and vaginal flora disturbance, which could be associated to either condiloma acuminnata or flat lesion, were also identified. Both bivariate and multivariate statistical analysis have shown that vulvovagnitis is not associated with the condiloma acuminnata or flat lesions caused by HPV in the female genital tract. In spite of this there was a high frequency of vulvovaginitis associated with both HPV clinical presentation (condiloma acumminata ¿ 50.5%) and flat lesions (54.8%). On the other hand, bivariate statistical analysis pointed to flat lesions being more frequentely associated to unstable marital status, intramuscular hormonal contraceptive and previous vaginal delivery. The multivariate regression analysis identified lower age group, unstable marital status, university level education, previous multiple gestations as being significantily associated with flat lesions. Lack of previous gestation and previous cesarian sections were associated with condiloma acumminata. Neither of the statistical analysis could highlight sexual behavior as a significant factor influencing HPV genital lesions. The conclusion reached was that, parallel to viral types of HPV, which infect the female genitalia, other factors can interfere in the type of lesion. Despite the fact of the freqüency of vulvovaginitis being high in these cases, it did not seem to interfere in the form of clinical or sub-clinical lesion presented. The conclusion reached was that parallel to HPV viral type, which infects the femal genital tract, there are other factors associated to different types of clinical manifestation / Mestrado / Tocoginecologia / Mestre em Tocoginecologia

Foi um ensaio clínico retrospectivo não randomizado, incluindo 65 mulheres operadas por incisão única e 67 por três incisões, entre 1986 e 1996. Para análise estatística realizamos os Testes Exato de Fischer, Qui-Quadrado, t de Student e regressão logística; curvas de sobrevida pelo método de Kaplan-Meyer, comparadas pelo teste de Wilcoxon, seguidas de regressão de Cox, com limite de 5% de significância estatística. Os grupos foram semelhantes com relação à idade, tabagismo, presença de síndromes clínicas, tipo e grau histológico. Houve mais estádios III no grupo de incisão única e mais linfonodos livres no grupo de três incisões. As pacientes tratadas com três incisões apresentaram significativamente menos complicações pós-operatórias imediatas (76% vs. 92%, p<0,05), menos deiscências (72% vs. 92%, p<0,01), menor necessidade de procedimentos secundários (76% vs. 94%, p<0,01) e menor tempo de internação (média de 19,4 dias vs. 38,7 dias, p<0,001). Ocorreram sete óbitos pós-operatórios: cinco com incisão única e dois com três incisões. A taxa de recidiva foi significativamente menor nas operadas com três incisões (19% vs. 35%, p<0,01) e com linfonodos livres de doença (6% vs. 15%, p<0,01). Após a regressão de Cox, apenas os linfonodos comprometidos influenciaram negativamente o tempo livre de doença. Concluímos que a vulvectomia por três incisões apresenta menos complicações que a incisão única, sem comprometer a eficácia terapêutica, independente do estádio da neoplasia / Abstract: The objective of this study was to compare post-operatory complications and recurrence rates in 132 women with invasive vulvar carcinoma treated with radical vulvectomy and bilateral groin lymphadenectomy performed by one or three incisions. It was a nonrandomized retrospective clinical essay, including 65 women operated by single incision and 67 by three incisions, between 1986 and 1996. Fischer¿s, Chi-square, Student¿s t tests followed by logistic regression were used in statistical analysis. Survival curves by Kaplan-Meyer method, compared by Wilcoxon test, followed by Cox regression, for the statistical significance limit of 5%. The groups were similar regarding age, tabagism, presence of clinical diseases, histologic type and grade. Pathologic stage III were significantly more frequent in the single incision group, while free lymph nodes were more frequent among three incisions group. The patients treated with triple incision showed statistically less frequent immediate complications (76% vs. 92%, p<0.05), less dehiscence (72% vs. 92%, p<0.01), secondary procedures were less necessary (76% vs. 94%, p<0.01) and shorter medium hospital stay (19,4 days vs. 38,7 days, p<0.001). Seven post-operative deaths were observed: five with single incision and two with triple incision. Recurrence was statistically lower in patients treated with triple incision (19% vs. 35%, p<0.01) and with 63 7. negative lymph nodes (6% vs. 15%, p<0.01). After Cox regression, only positive lymph nodes had negative influence in disease free survival. We concluded that vulvectomy by three incisions shows less complications than single incision, without compromising therapeutic efficacy, independently of stage / Mestrado / Tocoginecologia / Mestre em Medicina

Vulvar vestibulitis syndrome : an ultrastructural and epidemiological investigation

Sargeant, Penelope January 1996 (has links)
Vulvar Vestibulitis Syndrome (VVS) is a chronic inflammatory condition affecting the vestibular epithelium of the vulva, which has been estimated to affect 15% of the female population (Goetsch, 1991). Many studies have attempted unsuccessfully, to elucidate the cause of this condition, and few advancesh ave beenm adet owards the understandingo f the associatedin flammatory responseT. he initial, and principal aim of this investigation was to characterise normal vestibular epithelium using electron microscopy. The ultrastructural characteristics of normal vestibular epithelium were compared with closely related epithelia, and with vestibular epithelia from VVS patients. Other aims included an investigation of the epidemiological characteristics of VVS; an assessmenot f vulvar sensitivity over several months, and an evaluation of ketoconazole as a non-invasive treatment for VVS. Transmission electron microscopy, confirmed that vestibular epithelium was non-keratinised, and closely resembled oral and vaginal mucosae. Intermediate cells were predominant, characterised by pale staining cytokeratin filaments and glycogen deposits. Leukocytes were present in small numbers. Using SEM, superficial cells were characterised by an interlacing network of rounded microridges. By comparison, vestibular epithelium from VVS patients demonstrated the presence of numerous, intensely staining, apoptotic-like cells. These cells were associated with membrane bound cytoplasmic lobules and leukocytes of varying types. A similar ultrastructural appearance was observed in post-treatment biopsies. However, apoptotic-like cells appeared heavily vacuolated, and the number of cytoplasmic bodies present was increased. Mature plasma cells, NK-like cells and macrophages were common in the dermis. Leukocyte counts, demonstrated a significantly greater number of leukocytes in the VVS biopsies compared with the controls, however, there was no statistical difference in the number of leukocytes in pre and post-treatment samples. The presence of apoptotic-like cells accompanied by a significant inflammatory cell infiltrate, may suggest a cell signalling defect, resulting in the pain associatedw ith VVS. Treatment with ketoconazolec ream was found to have very little effect on either the number of leukocytes or the frequency of apoptotic-like cells as quantified using image analysis. The epidemiological characteristics of VVS patients were investigated using a structured questionnaire interview. All of the VVS patients interviewed fulfilled the diagnostic criteria established by Friedrich (1987), and epidemiological findings were generally consistent with previous epidemiological reports. Unique to this study, HPV infections were rare, however recurrent Candida infections and cystitis were commonly reported. The 'Vulvar Algesiometer', was designed and developed in Plymouth, to assist diagnosis and assessmenot f VVS patients. Using this equipment, VVS patients demonstrate heightened vestibular sensitivity when compared with control patients. The utilisation of a pain measuring device the 'Vulvar Algesiometer', in accordance with the questionnaire and ultrastructural investigation has formed a novel and balanced approach to the study of VVS. This study has demonstrated several distinct features of VVS which have not previously been described, features which may be important in elucidating the cause of this condition. These features centre around the presence of apoptotic-like cells and associated cytoplasmic bodies which have not previously been described in association with VVS.
