Denosumab given subcutaneously twice yearly for 36 months was associated with a reduction in the risk of vertebral, nonvertebral, and hip fractures in women with osteoporosis. (ClinicalTrials.gov number, NCT00089791.)

Bone is a complex tissue that provides mechanical support for muscles and joints, protection for vital organs, a mineral reservoir that is essential for calcium homeostasis, and the environment and niches required for haematopoiesis. The regulation of bone mass in mammals is governed by a complex interplay between bone-forming cells termed osteoblasts and bone-resorbing cells termed osteoclasts, and is guided physiologically by a diverse set of hormones, cytokines and growth factors. The balance between these processes changes over time, causing an elevated risk of fractures with age. Osteoclasts may also be activated in the cancer setting, leading to bone pain, fracture, spinal cord compression and other significant morbidities. This Review chronicles the events that led to an increased understanding of bone resorption, the elucidation of the signalling pathway mediated by osteoprotegerin, receptor activator of NF-κB (RANK) and RANK ligand (RANKL) and its role in osteoclast biology, as well as the evolution of recombinant RANKL antagonists, which culminated in the development of the therapeutic RANKL-targeted antibody denosumab.

The use of synthetic mesh to augment vaginal repair procedures for pelvic organ prolapse has increased in large part because of dissatisfaction with the success rates of traditional colporrhaphy. Its use, however, is controversial. Four randomized controlled studies comparing traditional colporrhaphy with vaginal repair using mesh augmentation had conflicting results. This unblinded, prospective, randomized controlled trial investigated whether mesh augmentation during vaginal repair would reduce the rate of recurrent prolapse at 12 months compared with traditional colporrhaphy. A total of 139 women with stage 2 or more prolapse who required both anterior and posterior compartment repair were randomized to mesh augmentation (mesh group, n ϭ 69) or colporrhaphy (no mesh group, n ϭ 70). Study subjects were enrolled between 2003 and 2005 at a tertiary teaching hospital. Prolapse was staged using the pelvic-organ-prolapse quantification (POP-Q) system. The primary study outcome was objective success of surgery defined as the absence of POP-Q stage 2 or more prolapse at 12 months following surgery. Questionnaires were used to assess secondary outcomes including symptoms, quality of life, and patient satisfaction.Of the 139 women, 63 of 69 (93.1%) in the mesh group and 61 of 70 (87.1%) in the no mesh group attended the 12-month follow-up. There was no significant difference at 12 months in objective success (POP-Q stage 0 or 1) between the mesh and no mesh groups (mesh: 81.0% ͓51/63͔ vs. no mesh: 65.6% ͓40/61͔; P ϭ 0.07). Although patients in both groups expressed a high level of satisfaction with the surgery and improved symptoms and parameters of quality of life compared to baseline, there was no statistically significant difference in these outcomes between the 2 groups (P ϭ ns). Postoperative complications in the mesh group included four cases (5.6%) of vaginal mesh exposure. At 12 months, de novo dyspareunia was reported in 27.8% (5/18) of the sexually active women without preoperative dyspareunia in the mesh group and in 41.7% (5/12) of those in the no mesh group. These differences were not significant (P ϭ 0.46).These findings show that anterior and posterior vaginal repair with mesh augmentation at 12 months after surgery does not result in significantly less recurrent prolapse than traditional colporrhaphy. GYNECOLOGY Volume 64, Number 12 OBSTETRICAL AND GYNECOLOGICAL SURVEY ABSTRACTThe presence of myomas can impair fertility. To preserve fertility in women with myomas wanting to become pregnant, myomectomy can be performed with laparotomy, laparoscopy, or hysteroscopy and achieve pregnancy rates of up to 70%. Advantages of laparoscopic techniques compared with laparotomy include shorter hospital stay, more rapid recovery, and less intra-abdominal adhesions. In addition, the overall complication rate is lower. Precise dissection and suturing, however, is especially difficult with traditional laparoscopy for myomas with a deep intramural and/or another unfavorable localization that have a probable impact on fec...
