Foetal intrauterine growth restrictions with Helicobacter pylori infection.

BACKGROUND: Helicobacter pylori infection has been associated with growth restriction in young children. AIM: To determine whether there is an association between H. pylori infection and intrauterine growth restriction. METHODS: Four hundred and forty-eight consecutive pregnant women (aged 15-44 years), attending for routine examinations in the third trimester, were enrolled. Clinical, demographic and previous obstetric data, as well as smoking history, were collected. At delivery, the weight, height, gender and status of the neonate were recorded; intrauterine growth restriction was defined if the birth weight was below the 10th percentile according to the gestational age for infants born in Australia. RESULTS: Eighty-nine (20%) women were seropositive for H. pylori. The prevalence of H. pylori was significantly lower in Caucasians (17%) vs. non-Caucasians (42%, P < 0.0001). There were 34 (7.5%) cases of intrauterine growth restriction (7% Caucasians, 16% Asians, 12% Aborigines and 0% Pacific Islanders). Intrauterine growth restriction was more common in H. pylori-seropositive women than in H. pylori-seronegative women [13.5% vs. 6%; odds ratio (OR) = 2.41; 95% confidence interval (CI), 1.14-5.08; P = 0.018]. A multiple logistic regression model revealed that smoking (OR = 3.55; 95% CI, 1.62-7.79; P = 0.002), maternal height (OR = 0.48; 95% CI, 0.28-0.80; P = 0.005) and H. pylori seropositivity (OR = 2.59; 95% CI, 1.12-5.95; P = 0.025) were all independent risk factors for intrauterine growth restriction. CONCLUSIONS: H. pylori infection in pregnant women may affect foetal intrauterine growth.

Symptoms and HPV infection of the vulva: clinical manifestations or mere coincidence?

Two hundred women with abnormal Pap smears and/or vulvar symptoms and 30 with normal Pap smears were investigated to determine the association between symptoms and (i) human papilloma virus infection of the vulva, and (ii) a spongiotic tissue reaction or a spongiotic dermatitis of the vulva. All had vulvar colposcopy and biopsy Human papilloma virus infection was diagnosed by histopathology and in situ hybridisation technique. HPV infection was present in biopsies of 48% of asymptomatic women and 33% with symptoms (p = 0.13) and HPV DNA in 37% of asymptomatic women and 31% with symptoms (p = 0.72). Spongiotic tissue reaction was diagnosed in 53.5% of asymptomatic women compared to 74% of symptomatic women (p = 0.007). This study suggests that vulvar symptoms are not clinical manifestations of HPV infection, but may be caused by dermatitis rather than HPV infection per se.

Vulvitis attributed to hypersensitivity to estrogen. A report of 11 cases.

BACKGROUND: Vulvitis that is refractory to all treatment remains a therapeutic challenge. Hypersensitivity to progesterone and estrogen has been recognized as a rare cause of premenstrual dermatoses. Such hypersensitivity seemed to be the cause of vulvitis in the patients described below. CASES: Nine women had treatment-resistant cyclic vulvitis and two patients had vulvitis develop after commencing hormone replacement therapy (HRT). These patients demonstrated delayed-type hypersensitivity responses by intradermal testing to endogenous estrogens, with two of the patients also reacting to intradermal testing with progesterone. A group of 19 healthy control subjects with no history of vulvar symptoms did not react to any test substance. Ten subjects with other vulvar dermatoses also did not react to any test substance. Of the nine patients with cyclic vulvitis, one recovered at menopause, and three responded to therapy aimed at lowering endogenous estrogen levels. One was able to control symptoms with a potent topical corticosteroid, and four elected not to be treated. Both patients with HRT-related vulvitis recovered when HRT was ceased. CONCLUSION: Hypersensitivity to estrogen appears to be implicated in chronic, cyclic vulvitis and vulvitis related to HRT in these patients. This is the first report of vulvitis due to estrogen hypersensitivity. The problem may not be rare and should be considered in patients with unexplained cyclic vulvitis unresponsive to standard therapy or in those developing noncandidal vulvitis on HRT. Specific therapy aimed at suppressing or antagonizing estrogen may be required in these patients.

A randomized clinical trial comparing oral misoprostol with synthetic oxytocin or syntometrine in the third stage of labour.

This is a multicentre, blocked, randomized trial to compare the efficacy of oral misoprostol 400 microg with current injectable uterotonic agents (oxytocin/ Syntometrine) used prophylactically in the third stage of labour. Main outcome measures were blood loss, use of a second uterotonic agent and difference in haemoglobin level from antepartum to postpartum. Data analysis from 863 women showed a statistically significant increase in both the mean blood loss (p < 0.001) and the rate of postpartum haemorrhage > 500 mL, (RR 2.72: 95% C1 1.73-4.27) in the misoprostol group compared to the oxytocin/Syntometrine group. The use of a second uterotonic agent was higher in the misoprostol group (RR 2.89: 95% Cl 2.00-4.18) as well as a greater decrease in postpartum haemoglobin (p = 0.015). Oral misoprostol 400 microg is significantly less effective than the traditional intramuscular uterotonic agents currently used and therefore cannot be considered as a viable option to these agents in the management of the third stage of labour.

Why we choose caesarean section: a prospective study.

We wished to inquire into the reasons why obstetricians choose Caesarean section as the preferred delivery mode and how they make that decision in individual settings. We therefore surveyed obstetricians to ascertain the obstetrical events at the time of decision and the reasons for the decision. Two hospitals with the same consultant medical staff were chosen for the study, The Jamison Private Hospital and the Nepean Hospital. The study group was analyzed using hospital, classification, parity, whether the procedure was elective or in labour, the stage of labour at which the Caesarean section was performed, and the primary and secondary reasons for the decision. Six hundred and twenty-four women were studied. When comparing the 2 institutions, there were 2 statistically significant findings. Firstly, the women at The Nepean Hospital were younger (27.9 +/- 5.6) than at Jamison Private Hospital (30.5 +/- 4.4; p < 0.001). Secondly, in the numbers of women undergoing Caesarean section in the 'failure to progress' category, there was a higher incidence (p < 0.001) at the private hospital. Apart from these differences, the 2 groups were remarkably similar.

The chronically symptomatic vulva: aetiology and management.

OBJECTIVE: To determine the causes and management of chronic vulval symptoms and to compare the findings in patients first presenting to a gynaecologist with those in patients first presenting to a dermatologist. DESIGN: A prospective study of 144 patients, approximately half each being referred to a gynaecologist and a dermatologist. Diagnosis was based on clinical history, vulvoscopy, vulval biopsy and bacteriology. Biopsies were examined by a histopathologist experienced in dermatopathology and gynaecological pathology. RESULTS: The two patient groups were similar in both range and frequency of conditions. The commonest cause of chronic vulval symptoms was dermatitis, which was found in 64% of our patients. Dermatitis occurred alone in 55% and was found in association with histological evidence of human papilloma virus (HPV) in a further 9%. These patients responded to simple dermatological methods, mainly topical corticosteroids. Histopathological evidence of HPV was encountered in only 23% of our patients, and of these 36% also demonstrated dermatitis on biopsy. Most responded to topical corticosteroids. Another 7% had lichen sclerosus, and all responded to potent topical corticosteroid. The remaining 15% demonstrated a range of diagnoses, including psoriasis, dysaesthetic vulvodynia, vulval intraepithelial neoplasia (VIN) and chronic candidiasis. The majority of patients had a corticosteroid responsive dermatosis rather than a gynaecological condition. CONCLUSIONS: The majority of patients with a chronically symptomatic vulva who present to either a gynaecologist or a dermatologist have a dermatological condition that responds to simple dermatological treatments. We believe that the presence or absence of the human papilloma virus is not relevant to most patients with a chronically symptomatic vulva and treatments should not be aimed at eradicating this virus. Histopathologists and gynaecologists who have focused on gynaecological disorders have often missed simple dermatological conditions that are easily treatable.

Thyrotoxicosis in pregnancy presenting as pancytopenia.

Delay in diagnosis of thyroid disease can result in morbidity and mortality. Thyroid disorders are not uncommon in the reproductive age group and therefore in pregnancy; recognition of both the common and the more unusual manifestations will optimize outcome.

A New South Wales population-based study of stillbirths weighing 2,500 g or more.

This paper describes factors associated with singleton stillbirths weighing 2,500 g or more, born in 1987 and reported to the NSW Midwives' Data Collection (MDC), a statewide perinatal data collection system. A total of 136 singleton stillbirths in this weight range were notified to the MDC, representing one-quarter of all singleton stillbirths in NSW. MDC records on these stillbirths were linked with perinatal death registrations for 125 of the 136. The death registrations indicated that fetal death occurred during labour in 20 cases, prior to the onset of labour in 98, and at an unknown time in the remaining 7 cases. Placental complications, including haemorrhage and functional abnormalities of the placenta, were the most frequent group of conditions associated with the stillbirths, being recorded as the underlying cause of death in 42 (34%) of the 125 cases. Cord complications (such as cord compression or cord around the neck) were given as the underlying cause of death in 30 cases (24%). The death certificate diagnosis was confirmed by autopsy in only 27 of the 125 cases (22%), although autopsies may have been done on a further 45 cases (36%). An adequate explanation of the cause appeared to be lacking for many of the fetal deaths. This highlights the importance of a thorough and systematic investigation of stillbirths. A list of standard investigations to be carried out following a stillbirth is proposed.

The inadequacies of instruments used for cervical screening.

Cervical cytology has a high false negative rate, especially for adenocarcinoma and its precursors. This study compares the traditional spatula with the cytobrush. Both the modified Ayre spatula and the cytobrush were found to be inadequate in a significant number of patients with known cytological atypia. It is concluded that inadequate sampling instruments make a contribution to false negative rates and that brush cytology is superior to rigid instrument cytology in routine cervical screening.
