Seroprevalence and assessment of risk factors for hepatitis C virus infection in pregnancy.

Screening for hepatitis B is routinely performed in most antenatal clinics. Whether the same should occur for hepatitis C needs to be assessed for each population by determining the prevalence of this infection within the community and whether any particular high-risk group can be identified. A series of 2,000 consecutive patients attending for antenatal care at the Mercy Hospital for Women, Melbourne, was tested for evidence of hepatitis C infection. The prevalence of hepatitis C infection in this group was 1.45% (95% confidence interval 0.97-2.1%). Significant independent risk factors were a history of intravenous drug use, blood transfusion and previous pregnancy ending prior to 20 weeks' gestation. Currently no treatment exists for hepatitis C and as there are no effective means of preventing transmission to the baby, routine screening cannot be justified in view of the low prevalence of this infection among antenatal patients. Selective screening of patients with relevant risk factors for hepatitis C should be carried out as the most efficient and cost-effective strategy in pregnancy.

Candida glabrata chorioamnionitis following in vitro fertilization and embryo transfer.

Candida glabrata is a yeast which is considered to be a commensal of the vagina with limited pathogenicity in the immunocompetent host. We report 2 cases of severe chorioamnionitis occurring in pregnancies achieved by in vitro fertilization techniques which resulted in preterm delivery and pregnancy loss. Candida glabrata as the causative agent was probably introduced into the uterus by the cannula at the time of embryo transfer. It is recommended that appropriate investigation of the microbial flora of the cervix be undertaken and treatment instituted prior to embryo transfer in order to prevent this complication.

Evaluation of patch testing in patients with chronic vulvar symptoms.

The Dermogynaecology Clinic was established at the Mercy Hospital for Women in 1989. Since its inception, 700 patients have been investigated and 15% were clinically diagnosed as having contact dermatitis. Primary irritant dermatitis was regarded as the common cause but to investigate the place of contact allergy 50 patients were patch tested to a standard battery, medicaments, preservatives, corticosteroids and miscellaneous allergens. Twenty-one patients (42%) had a total of 44 positive tests. The most common positive reactions were to nickel (22%), cobalt (6%), fragrances (12%), caine mix (6%) and ethylenediamine (8%). Medicaments and fragrances were regarded as important allergens. Corticosteroid and imidazole allergy was not a problem in this series of patients.

Human papillomavirus vulvitis: a new disease or an unfortunate mistake?

OBJECTIVE: To determine whether human papillomavirus (HPV) was responsible for symptoms in women with vulvar pruritus, pain and superficial dyspareunia who had been referred with a diagnosis of HPV vulvar disease made on clinical and/or colposcopic and/or histological grounds. DESIGN: In addition to standard clinical and laboratory investigations of the whole population, a sample of 15 test cases from the population of 71 women referred with a clinicopathological diagnosis of HPV vulvar disease, and two positive and 21 negative controls were assayed for HPV DNA. Polymerase chain reaction assays using L1 consensus primers were performed blinded to the clinicopathological diagnosis. SETTING: Dermogynaecology Clinic at Mercy Hospital for Women. SUBJECTS: Seventy-one women referred with a diagnosis of HPV vulvar disease. RESULTS: Thirteen cases which could be tested for HPV DNA were negative. Diagnoses other than HPV were found for the women's presentation in all cases. CONCLUSIONS: In the population studied, our investigations indicated that the clinicopathological diagnosis of HPV infection was incorrect and that HPV was not a cause of vulvar symptoms. We believe that the term HPV vulvitis is unfortunate as it has invited destructive treatments and drawn attention away from more likely causes of this difficult group of vulvar conditions.

Evaluation of serial cervical cytology in the assessment of preinvasive cervical neoplasia.

Examination was made of the cervical cytology in 107 patients who underwent cone biopsy with a subsequent diagnosis of severe dysplasia or carcinoma in situ (105) or microinvasive carcinoma (2). Multiple smears had been performed for each patient over a period of time. From the total number of smears a 'false-negative' cervical cytology rate of 10.3 per cent was found. The time interval from the initial abnormal smear until definitive surgical treatment was carried out was calculated. The cervical smear prior to cone biopsy was found to correlate with the histological diagnosis in only 46.7 per cent. The implications of performing repeated cervical cytology are discussed and a firm recommendation is made that patients with abnormal cervical smear be promptly referred to definitive treatment.

The association between vulvar condylomata acuminata, cervical wart virus infection and cervical intraepithelial neoplasia.

Vulvar condylomata acuminata are the commonest clinical expression of human papilloma virus infection of the female genital tract. Various epidemiological factors were examined in a group of patients with vulvar warts in whom the incidence of biopsy proven human papilloma virus infection of the cervix was 39.7% and the incidence of biopsy proven cervical intraepithelial neoplasia was increased significantly (16.2%).

The significance of cardiotocographic monitoring in pregnancy complicated by intrauterine growth retardation and prematurity.

Intrauterine growth retardation is a condition of chronic fetal compromise. The most accurate method of fetal assessment in this condition is by serial cardiotocography. In pregnancy associated with intrauterine growth retardation, abnormal cardiotocography with spontaneous decelerations may be an indicator of imminent fetal death in utero. Delivery should be effected immediately if the fetus is at a gestation where viability is probable.

Antenatal screening for congenital infection with rubella, cytomegalovirus and toxoplasma.

The sera of 3,463 pregnant women were screened, at the first antenatal visit, for antibodies to rubella, cytomegalovirus (CMV) and Toxoplasma gondii. Rubella antibodies were detected in 97.5%, CMV antibodies in 71% and toxoplasma antibodies in 45% of women. Asymptomatic toxoplasmosis occurred during pregnancy in 3 of 609 (0.5%) and primary CMV infection in 5 of 338 (1.5%) initially seronegative women whose sera were retested at the end of their pregnancies. The observed incidence of toxoplasmosis was similar to that calculated on the basis of the age-related prevalence of antibodies found in this study. On the basis of these observations it is estimated that congenital toxoplasmosis and congenital CMV infection due to primary maternal infection each occurs in up to 2/1,000 infants in this community. Very few of these infants have obvious abnormalities at birth, but follow-up studies elsewhere have shown that many of them suffer significant long-term sequelae. Routine antenatal screening for rubella antibodies is well established and justifiable for this preventable congenital infection. However, routine antenatal screening for CMV antibodies cannot be justified at present, since neither immunization nor treatment is available. Further information is required to determine the cost-effectiveness of routine antenatal screening for toxoplasma antibodies and treatment of proven maternal infection during pregnancy.
