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.)

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...

Denosumab, a fully human monoclonal antibody to RANKL, decreases bone remodeling, increases bone density, and reduces fracture risk. This study evaluates the time course and determinants of bone turnover marker (BTM) response during denosumab treatment, the percentage of denosumab-treated women with BTMs below the premenopausal reference interval, and the correlations between changes in BTMs and bone mineral density (BMD). The BTM substudy of the Fracture REduction Evaulation of Denosumab in Osteoporosis every 6 Months (FREEDOM) Trial included 160 women randomized to subcutaneous denosumab (60 mg) or placebo injections every 6 months for 3 years. Biochemical markers of bone resorption (serum C-telopeptide of type I collagen [CTX] and tartrateresistant acid phosphatise ) and bone formation (serum procollagen type I N-terminal propeptide [PINP] and bone alkaline phosphatase [BALP]) were measured at baseline and at 1, 6, 12, 24, and 36 months. Decreases in CTX were more rapid and greater than decreases in PINP and BALP. One month after injection, CTX levels in all denosumab-treated subjects decreased to levels below the premenopausal reference interval. CTX values at the end of the dosing period were influenced by baseline CTX values and the dosing interval. The percentage of subjects with CTX below the premenopausal reference interval before each subsequent injection decreased from 79% to 51% during the study. CTX and PINP remained below the premenopausal reference interval at all time points in 46% and 31% denosumab-treated subjects, respectively. With denosumab, but not placebo, there were significant correlations between CTX reduction and BMD increase (r ¼ À0.24 to À0.44). The BTM response pattern with denosumab is unique and should be appreciated by physicians to monitor this treatment effectively. ß

Previous studies have shown that 60 -70% of variance in peak bone density is determined genetically. The higher the peak bone density, the less likely an individual is to eventually develop osteoporosis. Therefore, the amount of bone accrued during postnatal and pubertal growth is an important determining factor in the development of osteoporosis. We evaluated the contribution of skeletal changes before, during, and after puberty to the development of peak bone density in C3H/HeJ (C3H) and C57BL/6J (B6) mice. Volumetric bone density and geometric parameters at the middiaphysis of femora were measured by peripheral quantitative computed tomography (pQCT) from days 7 to 56. Additionally, biochemical markers of bone remodeling in serum and bone extracts were quantified. Both B6 and C3H mice showed similar body and femoral weights. B6 mice had greater middiaphyseal total bone area and thinner cortices than did C3H mice. Within strains, males had thicker cortices than did females. C3H mice accumulated more minerals throughout the study, with the most rapid accumulation occurring postnatally (days 7-23) and during pubertal maturation (days 23-31). C3H mice had higher volumetric bone density as early as day 7, compared with B6 mice. Higher serum insulin-like growth factor I (IGF-I) was present in C3H mice postnatally at day 7 and day 14. Until day 31, B6 male and female mice had significantly higher serum osteocalcin than C3H male and female mice, respectively. Alkaline phosphatase (ALP) was found to be significantly higher in the bone extract of C3H mice compared with B6 mice at day 14. These data are consistent with and support the hypothesis that the greater amount of bone accrued during postnatal and pubertal growth in C3H mice compared with B6 mice may be caused by increased cortical thickness, increased endosteal bone formation, and decreased endosteal bone resorption. (1,2) About 60 -70% of variance in peak bone density is determined genetically, (3) and 40 -50% of peak bone density is accumulated during puberty.(4) Elucidation of the mechanisms regulating this dramatic increase in skeletal mass during puberty is important in the effort to identify potential preventive or interventive measures that would lower the risk of developing osteoporosis.*The view, opinions, and/or findings contained in this report are those of the author(s) and should not be construed as a position, policy, decision, or endorsement of the Federal Government or the National Medical Technology Testbed, Inc. 1 J.L.

Inherited defects of skull ossification often manifest as symmetric parietal foramina (PFM; MIM 168500). We previously identified mutations of MSX2 in non-syndromic PFM and demonstrated genetic heterogeneity. Deletions of 11p11-p12 (proximal 11p deletion syndrome, P11pDS; MIM 601224) are characterized by multiple exostoses, attributable to haploinsufficiency of EXT2 and PFM. Here we identify ALX4, which encodes a paired-related homeodomain transcription factor, as the PFM disease gene in P11pDS.
