ReviewContinuous or extended cycle vs. cyclic use of combined hormonal contraceptives for contraception.
The avoidance of menstruation through continuous or extended (greater than 28 days) administration of combination hormonal contraceptives (CHCs) has gained legitimacy through its use in treating endometriosis, dysmenorrhea, and menstruation-associated symptoms. Avoidance of menstruation through extended or continuous use of CHCs for reasons of personal preference may have additional advantages to women, including improved compliance, greater satisfaction, fewer menstrual symptoms, and less menstruation-related absenteeism from work or school. ⋯ The 2014 update yielded four additional trials but unchanged conclusions. Evidence from existing randomized control trials comparing continuous or extended-cycle CHCs (greater than 28 days of active combined hormones) to traditional cyclic dosing (21 days of active hormone and 7 days of placebo, or 24 days of active hormone and 4 days of placebo) is of good quality. However, the variations in type of hormones and time length for extended-cycle dosing make a formal meta-analysis impossible. Future studies should choose a previously described type of CHC and dosing regimen. More attention needs to be directed towards participant satisfaction, continuation, and menstruation-associated symptoms.

Review Meta AnalysisImmediate postabortal insertion of intrauterine devices.
Background The use of an effective contraceptive may be necessary after an abortion. Insertion of an intrauterine device (IUD) may be done the same day or later. Immediate IUD insertion is an option since the woman is not pregnant, pain of insertion is less because the cervical os is open, and her motivation to use contraception may be high. ⋯ Authors' conclusions Moderate quality evidence shows that insertion of an IUD immediately after abortion is safe and practical. IUD expulsion rates appear higher immediately after abortions compared to delayed insertions. However, at six months postabortion, IUD use is higher following immediate insertion compared to delayed insertion.

Review Meta AnalysisAntibiotics for acute pyelonephritis in children.
Urinary tract infection (UTI) is one of the most common bacterial infections in infants. The most severe form of UTI is acute pyelonephritis, which results in significant acute morbidity and may cause permanent kidney damage. There remains uncertainty regarding the optimum antibiotic regimen, route of administration and duration of treatment. This is an update of a review that was first published in 2003 and updated in 2005 and 2007. ⋯ This updated review increases the body of evidence that oral antibiotics alone are as effective as a short course (three to four days) of IV antibiotics followed by oral therapy for a total treatment duration of 10 to 14 days for the treatment of acute pyelonephritis in children. When IV antibiotics are given, a short course (two to four days) of IV therapy followed by oral therapy is as effective as a longer course (seven to 10 days) of IV therapy. If IV therapy with aminoglycosides is chosen, single daily dosing is safe and effective. Insufficient data are available to extrapolate these findings to children aged less than one month of age or to children with dilating vesicoureteric reflux (grades III-V). Further studies are required to determine the optimal total duration of antibiotic therapy required for acute pyelonephritis.

Review Comparative StudyHysterectomy versus hysterectomy plus oophorectomy for premenopausal women.
Background Prophylactic oophorectomy alongside hysterectomy in premenopausal women is a common procedure. The decision to remove or conserve the ovaries is often based on the perceived risk for ovarian cancer and the need for additional gynaecological surgical interventions,and is weighed against the perceived risk of negative health effects caused by surgically induced menopause. The evidence needed to recommend either prophylactic bilateral oophorectomy or conservation of ovaries at the time of hysterectomy in premenopausal women is limited. ⋯ Therefore, no data could be included in this review. Authors' conclusions The conclusions of this review are limited by a lack of RCTs. Although no evidence is available from RCTs, there is growing evidence from observational studies that surgical menopause may impact negatively on cardiovascular health and all cause mortality.
