A population-based, controlled study of the relation between HIV infection and cervical neoplasia.

OBJECTIVE: To study a geographically defined population of women exposed to a drug-related risk for human immunodeficiency virus (HIV), together with carefully matched neighbourhood controls, in order to examine (1) the proportion of different groups having cervical cytopathology screening; (2) the association between HIV infection and cervical intraepithelial neoplasia; (3) the independent effect of CD4+ lymphocyte count and duration of HIV infection; and (4) the correspondence between cervical cytopathology and colposcopically directed biopsy. DESIGN: A population-based study. SUBJECTS: All women domiciled in Lothians with the following characteristics: between 1983 and 1987 they had a history of injection drug use or a seropositive partner with a history of injection drug use; they had a pregnancy after that exposure where their serostatus was known. In addition, neighbourhood controls were identified by computer matching for the following criteria--post-code sector, housing deprivation score, age, parity, pregnancy outcome, ethnic group, year of pregnancy, smoking. MAIN OUTCOME MEASURES: Search was carried out for the cervical smear nearest in time to the index pregnancy end date, providing serostatus was known at that time. All identified smears were assessed by a cytopathologist without knowledge of clinical information, study group or serostatus. RESULTS: Of 376 women, appropriate cervical smears were identified for 336. The proportions screened in the different groups were similar. There were more abnormal smears in the seropositive group than in the drug-related seronegative (P < 0.01) or the neighbourhood control groups (P < 0.001). HIV-infected women with abnormal smears had lower CD4+ lymphocyte counts (P < 0.0005). There was a reasonable correspondence between cytopathological classification and histological grading, and this was of similar strength in cases and controls (weighted kappa 0.72, 0.74). CONCLUSIONS: There is a definite relation between HIV infection and cervical intraepithelial neoplasia. This is related to immune depletion but whether this is the sole mechanism for the association is unclear.

Early stage cervical cancer: psychosocial and sexual outcomes of treatment.

Eighty-three women, mean age 45 years, successfully treated by surgery (S) or radiotherapy (RT) for stage 1b cervical cancer were assessed a mean of 97 weeks post treatment. Forty to 50% reported persistent tiredness, lack of energy and weight gain. Sixty per cent had not resumed their full premorbid functional status. Mean scores for anxiety and depression were higher than general population means and this sample scored higher for psychological distress than published data quoted for disease free cancer patients. These women reported many concerns about cervical cancer, most commonly fear of recurrent disease (91%). More than one-third blamed themselves for the disease. There were no significant differences in functional outcome or psychological status between treatment groups or by age or time since treatment. Psychological distress scores were significantly correlated with physical complaints (P < 0.001) and functional outcomes (P < 0.02). For the 61 women who were sexually active, sexual function post-treatment was rated as significantly poorer than subjectively recalled premorbid sexual function (P < 0.005). RT treated patients were more likely to report pain on intercourse and loss of enjoyment. Psychological as well as physical problems were highly correlated with sexual outcome (P < 0.01) 44% were unable to talk adequately with their partners about their experience. The majority felt they needed more information about cervical cancer, its treatment and how to help themselves rehabilitate. Forty-nine per cent would have liked to have had counselling. Even with the same physical morbidity the functional, emotional and sexual status of these women could be improved by giving more attention to their psychological and sexual concerns.

Diffuse leiomyomatosis of the uterus with local pelvic spread.

The clinical and pathological findings of a case of diffuse leiomyomatosis of the uterus are described. The unique feature of this case is the extension of the disease process to the pelvic mesocolon. The diagnostic difficulties encountered in the histological assessment of smooth muscle tumors of the uterus are discussed.

Cervical intraepithelial neoplasia in patients with breast cancer: a cytological and colposcopic study.

Twenty-six patients with treated breast cancer who had been randomised previously to receive combination chemotherapy including alkylating agents (n = 14) or to undergo oophorectomy (n = 12) following surgery underwent cytological and colposcopic screening of the uterine cervix. Colposcopically directed cervical punch biopsies were taken from all patients in whom a colposcopic abnormality was detected. Breast cancer patients were compared with 79 controls with normal cervical cytology and no known breast malignancy. Colposcopically directed punch biopsies were taken from the cervical transformation zone of all controls. Significantly more breast cancer patients who had received chemotherapy (43%) than controls (10%) had CIN (P < 0.01) and significantly more patients who had received chemotherapy (14%) than controls (3%) had CIN 2 or 3 (P < 0.05). The proportion of breast cancer patients in the oophorectomy group with CIN (17%) did not differ significantly from the control group. No case of CIN was detected by cervical cytology. This study suggests that breast cancer patients receiving combination chemotherapy including alkylating agents are at increased risk of CIN, and that cervical cytology alone may be an inadequate form of screening for these patients.

The cytological detection of persistent cervical intraepithelial neoplasia after local ablative treatment: a comparison of sampling devices.

OBJECTIVE: To determine whether the cytological detection of persistent cervical intraepithelial neoplasia (CIN) after local ablative treatment is improved by the use of sampling devices other than the Ayre's spatula. DESIGN: A randomized controlled study. SETTING: Lothian Area Colposcopy Clinic. SUBJECTS: 856 patients who had received local therapy (CO2 laser or cold coagulation) for CIN II or III between 9 and 30 months earlier. INTERVENTION: Each patient had three consecutive cervical smears taken, one with the Ayre's spatula, one with either the Aylesbury, the Rocket or the Multispatula device, and finally one with the Cytobrush. The allocation of which spatula and the order of the first two was randomized. Each patient had a colposcopic examination immediately after the smears were taken. MAIN OUTCOME MEASURES: A comparison of the detection of histologically proven persistent CIN by the Ayre's spatula with the detection of persistent disease by alternative sampling devices. RESULTS: Of the 856 patients 130 had histologically proven persistent CIN. Another 98 had suspicious findings on colposcopy but punch biopsies reported as histologically normal. Of the remaining patients with normal colposcopy 130 were randomly selected to form a control group. The cervical smears from these 358 women were reported. Significantly fewer Ayre's samples contained endocervical cells than Aylesbury samples (47% vs 59%, difference 12%; 95% CI 3%-21%; P less than 0.001), Rocket samples (47% vs 67%; difference 20%, 95% CI; 12%-32%; P less than 0.001) or Multispatula samples (47% vs 76%; difference 29%, 95% CI 19-38%; P less than 0.001). When punch biopsies contained CIN, dyskaryotic cells were seen in 10% of Ayre's samples, 4.3% of Aylesbury samples, 8.3% of Rocket samples, and in no smear taken with the Multispatula. Obtaining a third smear with the Cytobrush did not substantially improve the detection rate of dyskaryosis. Neither the order of use of the spatulas, the form of initial treatment nor the size of the transformation zone had any apparent effect on the cytological detection of persistent CIN. CONCLUSIONS: We recommend that surveillance of patients who have received local ablative therapy for CIN should be by both cytology and colposcopy, and that cytological samples should be obtained using the Ayre's spatula.

Cisplatinum and prednimustine, an active regimen for advanced epithelial ovarian cancer.

80 patients with advanced epithelial ovarian carcinoma were treated for 6 months with cisplatinum and prednimustine following initial surgery. Response to treatment was assessed by second-look surgery. The objective response rate was 69% with 38% achieving a complete response for up to 55 months. The toxicity of this regimen was acceptable. Statistically, de-bulking or partial de-bulking had a significant beneficial effect on the likelihood of a complete response. The best survival figures were associated with maximum de-bulking. The combination of cisplatinum and prednimustine is a new and active regimen for operable advanced epithelial ovarian carcinoma.

Intraplacental choriocarcinoma: a case report.

A recent paper has again drawn attention to the occurrence of intraplacental choriocarcinoma. We present a similar case in which a small intraplacental choriocarcinoma was identified after delivery of a full-term stillborn fetus. Interpretation of this lesion was influenced by the presence of normal villi and its full significance appreciated only after diagnosis of choriocarcinoma in the mother. This case presents histological proof that choriocarcinoma may arise from an otherwise normal placenta.

Detection of human papillomavirus in skin and genital lesions of renal allograft recipients by in situ hybridization.

Renal allograft recipients have an increased incidence of malignancy including squamous carcinoma of cervix and skin. There is growing evidence that human papillomavirus (HPV) has a part to play in malignant transformation at these sites. We have previously identified HPV DNA in the skin and genital lesions of such patients by dot and Southern blotting. In situ hybridization studies, using biotinylated DNA probes for HPV 4, 5 and 8 in skin lesions and 6, 11, 16 and 18 in genital lesions, were performed on tissues derived from the same group of patients. In the cutaneous lesions, only 25% of the specimens probed were found to contain virus by in situ hybridization; 60% of these specimens were found to harbour virus by dot and Southern blotting. In situ hybridization revealed HPV 16 and/or 18 in 86% of the genital lesions probed.

Synchronous colonic adenocarcinoma and extragenital malignant mixed mesodermal tumour.

A synchronous occurrence of large bowel adenocarcinoma and extragenital malignant mixed mesodermal tumour (MMMT) is reported. This case represents the sixth extragenital MMMT reported in the literature.

Cervical intraepithelial neoplasia in lymphoma patients: a cytological and colposcopic study.

Twenty-seven patients with Hodgkin's (n = 19) and non-Hodgkin's (n = 8) lymphomas underwent cytological and colposcopic screening of the uterine cervix. Colposcopically directed cervical punch biopsies were taken from all patients in whom a colposcopic abnormality was detected. Lymphoma patients were compared with 79 controls with normal cervical cytology and no known haematological abnormality. Colposcopically directed punch biopsies were taken from the cervical transformation zone of all controls. Significantly more lymphoma patients (19%) than controls (3%) had CIN II or III (P less than 0.01) and cervical human papillomavirus infection, as judged by the presence of koilocytes (52% of lymphoma patients; 27% of controls; P less than 0.02). All six lymphoma patients with CIN had Hodgkin's disease (HD), and five had received combination chemotherapy. Half of the cases of CIN in lymphoma patients and all the cases of CIN in control patients were not detected by cervical cytology. This study suggests that female patients with HD are at increased risk of CIN, and that cervical cytology alone may be an inadequate form of screening for these patients.

Sheep-acquired severe Chlamydia psittaci infection in pregnancy.

There have been five confirmed cases of severe Chlamydia psittaci infection during pregnancy, three having been treated in Edinburgh, Scotland. The most recent case is presented and previous experience is reviewed. The illness usually causes thrombocytopenia with disseminated intravascular coagulation, renal failure and hepatic dysfunction during the late second and early third trimester. The outcome for the fetus is usually fatal and the infection only resolves after delivery or abortion. The main hope is for education to prevent infection occurring in susceptible populations.

Randomised trial comparing prednimustine with combination chemotherapy in advanced ovarian carcinoma.

A total of 76 patients with advanced epithelial ovarian carcinoma were randomised to receive 6 months of treatment with either a combination of hexamethylmelamine, 5-fluorouracil, cisplatin and prednimustine or prednimustine alone following initial surgery. Pathologically confirmed response rates were 35% for combination chemotherapy and 28% for prednimustine, and the overall survival was identical for the two groups. Seven patients achieved a pathologically defined complete response, one of whom relapsed at 8 months; the others remain disease-free 18-36 months (median, 23 months) after presentation. The extent of initial surgery significantly affected the survival of patients receiving prednimustine but not of those receiving combination chemotherapy. Prednimustine can produce durable responses in advanced ovarian cancer using a schedule that results in negligible toxicity.

Human papillomavirus infection and cervical intraepithelial neoplasia in women with renal allografts.

An increased prevalence of cervical cancer has been observed in immunosuppressed women, but controlled studies are rare. Biopsy specimens from 49 women with renal allografts and 69 non-immunosuppressed controls (with no history of cervical intraepithelial neoplasia, vulval warts, or abnormal results of cervical smear tests) were assessed for colposcopic appearance, cytological and histological diagnosis, and the presence of human papillomavirus types 6/11 and 16/18 DNA sequences. At colposcopy 26 (53%) of the women with allografts had cervical abnormalities compared with 20 (29%) of the controls. The prevalence of cervical intraepithelial neoplasia was significantly higher in the women with allografts (24 (49%) compared with 7 (10%]. The overall rate of detection of human papillomavirus DNA did not differ significantly between the two groups. There was however, a significant difference in the rate of detection of human papillomavirus type 16/18 DNA (27% in the women with allografts and 6% in the controls). These data confirm that pathological and virological changes affecting the cervix are significantly increased in immunosuppressed women and emphasise the need for regular colposcopic examination.

Feto-maternal HLA compatibility does not have a major influence on human pregnancy except for lymphocytotoxin production.

Several studies have supported the hypothesis that the maternal immune response to incompatible paternal HLA antigens present on the conceptus may influence pregnancy outcome. In order to relate feto-maternal histocompatibility directly to pregnancy course and characteristics, complete HLA-A, B and DR types were obtained from 132 healthy family groups consisting of mothers, fathers and neonates. The distribution of feto-maternal HLA compatibility was heavily skewed towards incompatibility, with 90% of fetuses being mismatched at 2 or 3 loci. There was no segregation distortion of paternal haplotypes, however, and the number of feto-maternal mismatches was close to that expected theoretically. More than 2% of the neonates were perfectly HLA-A, B and DR compatible with their mothers. The degree of feto-maternal HLA disparity showed no significant correlation with sex of neonate, birthweight, placental weight, maternal plasma alpha-fetoprotein or parity of the mother. Feto-maternal HLA disparity did, however, correlate significantly with maternal lymphocytotoxin production, even after allowance was made for parity (P less than 0.01). We conclude that feto-maternal HLA compatibility per se does not have a major influence on pregnancy outcome, and in particular is unlikely to predispose to spontaneous abortion; so an absence of antigen sharing between spouses experiencing recurrent spontaneous abortions should not be regarded in itself as a contraindication to offering immunotherapy to such couples.

Histocompatibility studies in pre-eclampsia.

Full HLA-A, B and DR types were obtained for 22 families (mothers, fathers and neonates) associated with severe (proteinuric) pre-eclampsia, 21 families associated with mild pre-eclampsia, and 132 families associated with normal pregnancies. There was an increased frequency of DR4 (relative risk 3.6: p less than 0.003, uncorrected) in both neonates and mothers of the severe pre-eclampsia families when compared to the normotensive controls. There were no significant differences between either pre-eclampsia group and controls in HLA antigen homozygosity, HLA antigen sharing or in lymphocytotoxin production.

Severe pre-eclampsia in multiparous women: indication of an environmental triggering agent?

Two case histories are described with conflicting implications for the etiopathogenesis of pre-eclampsia. In both, typical proteinuric pre-eclampsia developed despite a history of previous normotensive pregnancy. In the first case, the disease was associated with a change of husband, consistent with the view that pre-eclampsia arises from an inadequate maternal immune response to paternal antigens inherited by the fetus. The second case, however, concerned a woman who developed pre-eclampsia for the first time in her third pregnancy by the same reproductive partner. We conclude that either more than one underlying cause can result in the clinical syndrome of pre-eclampsia, or that pre-eclampsia is caused by an environmental factor. The possibility that pre-eclampsia may be initiated by an infectious agent is briefly explored in the light of the clinical histories described and well-established epidemiological, clinical and laboratory data.

Grading of cervical dysplasias by frozen section.

Grading of cervical dysplasias at colposcopy by means of rapid frozen section avoids the delay inevitable with paraffin sections. The immediacy of the diagnosis benefits the patient, who can be treated at her first visit. A comparison of grading by frozen sections with paraffin sections has confirmed the safety of the frozen method. Additional advantages are opportunities for optimum orientation and "rescue" of specimens, improved colposcopic training, and the facilitation of special investigations on fresh cervical tissue.
