ReviewTrial of instrumental delivery in theatre versus immediate caesarean section for anticipated difficult assisted births.
The majority of women have spontaneous vaginal births, but some women need assistance in the second stage with delivery of the baby, using either the obstetric forceps or vacuum extraction. Rates of instrumental vaginal delivery range from 5% to 20% of all births in industrialised countries. The majority of instrumental vaginal deliveries are conducted in the delivery room, but in a small proportion (2% to 5%), a trial of instrumental vaginal delivery is conducted in theatre with preparations made for proceeding to caesarean section. ⋯ There is no current evidence from randomised trials to influence practice.

Review Meta AnalysisMethenamine hippurate for preventing urinary tract infections.
Methenamine salts are often used as an alternative to antibiotics for the prevention of urinary tract infection (UTI). This review was first published in Issue 1, 2002 and updated in Issue 4, 2007. ⋯ Methenamine hippurate may be effective for preventing UTI in patients without renal tract abnormalities, particularly when used for short-term prophylaxis. It does not appear to work in patients with neuropathic bladder or in patients who have renal tract abnormalities. The rate of adverse events was low, but poorly described.There is a need for further large well-conducted RCTs to clarify this question, particularly for longer term use for people without neuropathic bladder.

Review Meta AnalysisChemotherapy for metastatic and recurrent cervical cancer.
Cervical cancer is the second most common cancer among women up to 65 years of age and is the most frequent cause of death from gynaecological cancers worldwide. A woman's risk of developing cervical cancer by 65 years of age ranges from 0.69% in developed countries to 1.38% in developing countries. Although screening by Pap smear should mean early detection at a curable stage for most women, many still present with advanced or metastatic disease with a worse prognosis. The addition of platinum-based chemotherapy to radiotherapy has improved outcome compared to radiotherapy alone; however, 30% to 50% fail to respond to treatment or develop recurrent disease. There are no standard treatment options for these patients, although platinum-based chemotherapy is frequently used and trials are on-going. ⋯ Combination cisplatin-based chemotherapy could be a viable option for patients of good performance status with recurrent/metastatic cervical cancer, but further trials that report adequate survival and QoL data are sought. Response rates and improvements in survival are low. Cisplatin-based combinations have significant toxicity. Outcomes are poor and novel cytotoxic/biological agents and optimal scheduling need further investigation. Future trials need to stratify for and perform planned subgroup analysis with respect to previous treatment and site of recurrence.

ReviewCyclo-oxygenase (COX) inhibitors for preventing preterm labour.
Preventing preterm labour is the most important step in preventing preterm birth. Prostaglandins play an important role in labour and birth. Prostaglandin production can be obstructed by inhibition of the cyclo-oxygenase (COX) enzyme and this may arrest uterine contraction. A Cochrane review on COX inhibitors for the treatment of preterm labour found insufficient data to draw conclusions about its effectiveness. ⋯ There was very little evidence about using COX inhibitors for preventing preterm labour. There are inadequate data to make any recommendation about using COX inhibitor in practice to prevent preterm labour. Future research should include follow-up of the babies to examine the short-term and long-term effects of COX inhibitors.

ReviewMale involvement for increasing the effectiveness of prevention of mother-to-child HIV transmission (PMTCT) programmes.
Despite efforts to increase the uptake of prevention of mother to child transmission of HIV (PMTCT) services, coverage is still lower than desired in developing countries. A lack of male partner involvement in PMTCT services is a major barrier for women to access these services. ⋯ We found only one eligible study that assessed the effectiveness of male involvement in improving women's uptake of PMTCT services, which only focused on one part of the perinatal PMTCT cascade. We urgently need more rigorously designed studies assessing the impact of male engagement interventions on women's uptake of PMTCT services to know if this intervention can contribute to improve uptake of PMTCT services and reduce vertical transmission of HIV in children.
