ReviewMaternal hydration for increasing amniotic fluid volume in oligohydramnios and normal amniotic fluid volume.
Oligohydramnios (reduced amniotic fluid) may be responsible for malpresentation problems, umbilical cord compression, concentration of meconium in the liquor, and difficult or failed external cephalic version. Simple maternal hydration has been suggested as a way of increasing amniotic fluid volume in order to reduce some of these problems. ⋯ Simple maternal hydration appears to increase amniotic fluid volume and may be beneficial in the management of oligohydramnios and prevention of oligohydramnios during labour or prior to external cephalic version. Controlled trials are needed to assess the clinical benefits and possible risks of maternal hydration for specific clinical purposes.

This review is superseded by the published Cochrane Review, Taylor 2023: https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014785.pub2/full. ⋯ Given the level of investment in growth monitoring worldwide, it is surprising there is so little research evaluating its potential benefits and harms.

Around 120 million women worldwide suffer from Trichomonas vaginalis vaginitis every year. The infection is sexually transmitted and is believed to facilitate HIV transmission. The objective of the review is to assess the effects of various treatment strategies for trichomoniasis in women. ⋯ Parasitological cure can be achieved by single oral dose of nitroimidazoles. Further research should focus on developing effective partner treatment strategies to prevent re-infections and reduce trichomoniasis prevalence.

ReviewOvulation induction with urinary follicle stimulating hormone versus human menopausal gonadotropin for clomiphene-resistant polycystic ovary syndrome.
The risks of multiple pregnancy and ovarian hyperstimulation syndrome (OHSS) are increased in women with clomiphene resistance WHO group 2 dysfunction undergoing ovulation induction as well as the risk of spontaneous abortion if conception takes place. Semi-purified preparations of FSH have been developed in an effort to reduce the impact of exogenous LH, relatively high levels of which are present in human menopausal gonadotropin (hMG). Ovulation induction in women with clomiphene resistant WHO group 2 dysfunction who often have clinical features of polycystic ovarian syndrome (PCOS), is a major challenge. The risks of multiple pregnancy and ovarian hyperstimulation syndrome (OHSS) are increased in this population. There also appears to be an increased risk of spontaneous abortion in those who conceive, perhaps associated with elevated LH levels. Semi-purified preparations of FSH have been developed in an effort to reduce the impact of exogenous LH, relatively high levels of which are present in human menopausal gonadotrophins. ⋯ In women with PCOS, no significant difference could be demonstrated between FSH and hMG, in terms of pregnancy rate. However, given similar cost, potential advantages in terms of purity and a possible reduction in OHSS risk, highly purified or recombinant FSH are likely to be widely adopted in the future. Further research should consider live birth as a primary clinical outcome, given concerns over the association between high androgen and LH levels with spontaneous abortion risk.

Endotracheal tubes are foreign bodies that may injure the upper airway causing laryngeal edema. This in turn may result in failure of extubation in preterm infants. Corticosteroids have been used prophylactically to reduce upper airway obstruction and facilitate extubation. ⋯ Implications for practice Dexamethasone reduces the need for endotracheal reintubation of neonates after a period of IPPV. In view of the lack of effect in low risk infants and the documented and potential side effects, it appears reasonable to restrict its use to infants at increased risk for airway edema and obstruction, such as those who have received repeated or prolonged intubations. Implications for research Issues of dosage and applicability to the extremely low birthweight population could be addressed in future trials. Longer term outcomes such as chronic lung disease, duration of assisted ventilation and length of hospital stay should also be examined.
