    <p>Abstract</p> <p>Background</p> <p>Previous research has shown a loss of bone mineral density (BMD) during pregnancy. This loss has been correlated to the occurrence of back pain symptoms during pregnancy. The objective of this study was to evaluate whether persistence of back pain symptoms 2 years after pregnancy could be associated with BMD changes as measured by quantitative USG of the os calcis.</p> <p>Methods</p> <p>A cohort of patients who reported significant back pain symptoms during pregnancy were surveyed for persistent back pain symptoms 24 to 28 months after the index pregnancy. Os calcis BMD was measured by quantitative ultrasound and compared with the BMD values during pregnancy.</p> <p>Results</p> <p>A cohort of 60 women who had reported significant back pain symptoms in their index pregnancy completed a 24-28 months follow-up survey and BMD reassessment. Persistence of significant back pain symptoms was seen in 24 (40%) of this cohort. These women had higher BMD loss during pregnancy compared to those without further pain (0.047 Vs 0.030 g/cm<sup>2</sup>; p = 0.03). Those that remained pain free after pregnancy appeared to have completely recovered their BMD loss in pregnancy, while those with persistent pain had lower BMD values (ΔBMD - 0.007 Vs - 0.025 g/cm<sup>2</sup>; p = 0.023) compared to their early pregnancy values.</p> <p>Conclusion</p> <p>Persistence of back pain symptoms after pregnancy could be related to an inability to recover fully from BMD loss during the index pregnancy.</p

    To validate the clinical efficacy and practical feasibility of massively parallel maternal plasma DNA sequencing to screen for fetal trisomy 21 among high risk pregnancies clinically indicated for amniocentesis or chorionic villus sampling. Diagnostic accuracy validated against full karyotyping, using prospectively collected or archived maternal plasma samples. Prenatal diagnostic units in Hong Kong, United Kingdom, and the Netherlands. 753 pregnant women at high risk for fetal trisomy 21 who underwent definitive diagnosis by full karyotyping, of whom 86 had a fetus with trisomy 21. Intervention Multiplexed massively parallel sequencing of DNA molecules in maternal plasma according to two protocols with different levels of sample throughput: 2-plex and 8-plex sequencing. Proportion of DNA molecules that originated from chromosome 21. A trisomy 21 fetus was diagnosed when the z score for the proportion of chromosome 21 DNA molecules was >3. Diagnostic sensitivity, specificity, positive predictive value, and negative predictive value were calculated for trisomy 21 detection. Results were available from 753 pregnancies with the 8-plex sequencing protocol and from 314 pregnancies with the 2-plex protocol. The performance of the 2-plex protocol was superior to that of the 8-plex protocol. With the 2-plex protocol, trisomy 21 fetuses were detected at 100% sensitivity and 97.9% specificity, which resulted in a positive predictive value of 96.6% and negative predictive value of 100%. The 8-plex protocol detected 79.1% of the trisomy 21 fetuses and 98.9% specificity, giving a positive predictive value of 91.9% and negative predictive value of 96.9%. Multiplexed maternal plasma DNA sequencing analysis could be used to rule out fetal trisomy 21 among high risk pregnancies. If referrals for amniocentesis or chorionic villus sampling were based on the sequencing test results, about 98% of the invasive diagnostic procedures could be avoided.published_or_final_versio

    A systematic review of randomised controlled trials on the effectiveness of exercise programs on lumbo pelvic pain among postnatal women

    Background: A substantial number of women tend to be affected by Lumbo Pelvic Pain (LPP) following child birth. Physical exercise is indicated as a beneficial method to relieve LPP, but individual studies appear to suggest mixed findings about its effectiveness. This systematic review aimed to synthesise evidence from randomised controlled trials on the effectiveness of exercise on LPP among postnatal women to inform policy, practice and future research. Methods: A systematic review was conducted of all randomised controlled trials published between January 1990 and July 2014, identified through a comprehensive search of following databases: PubMed, PEDro, Embase, Cinahl, Medline, SPORTDiscus, Cochrane Pregnancy and Childbirth Group’s Trials Register, and electronic libraries of authors’institutions. Randomised controlled trials were eligible for inclusion if the intervention comprised of postnatal exercise for women with LPP onset during pregnancy or within 3 months after delivery and the outcome measures included changes in LPP. Selected articles were assessed using the PEDro Scale for methodological quality and findings were synthesised narratively as meta-analysis was found to be inappropriate due to heterogeneity among included studies. Results: Four randomised controlled trials were included, involving 251 postnatal women. Three trials were rated as of ‘good’ methodological quality. All trials, except one, were at low risk of bias. The trials included physical exercise programs with varying components, differing modes of delivery, follow up times and outcome measures. Intervention in one trial, involving physical therapy with specific stabilising exercises, proved to be effective in reducing LPP intensity. An improvement in gluteal pain on the right side was reported in another trial and a significant difference in pain frequency in another. Conclusion: Our review indicates that only few randomised controlled trials have evaluated the effectiveness of exercise on LPP among postnatal women. There is also a great amount of variability across existing trials in the components of exercise programs, modes of delivery, follow up times and outcome measures. While there is some evidence to indicate the effectiveness of exercise for relieving LPP, further good quality trials are needed to ascertain the most effective elements of postnatal exercise programs suited for LPP treatment

    Objective: To evaluate the relationship between maternal smoking and fetal congenital central nervous system malformations. Methods: Retrospective review of all cases of fetal congenital malformations of the central nervous system (CNS) identified at or shortly after birth over a 10-year period (1986-1995) in a university teaching obstetric department. Results: The total number of CNS abnormalities identified was 79, constituting 0.13% of all deliveries over the period (n = 59,392) and 4.7% of all congenital malformations (n = 1678). The incidence of smoking mothers was 1.64% over the study period. Four babies had hydranencephaly, 3 of these mothers being smoking teenagers. The odds ratio of having a hydranencephalic fetus in smoking mothers compared to non-smokers was 56 (95% CI 7.41-427) in the group with CNS abnormalities, 136 (95% CI 14.5-1280) in the group including all congenital malformations, and 179 (95% CI 18.6-1719) in the group including all deliveries. Conclusion: Maternal smoking did not appear to increase the incidence of fetal congenital CNS abnormalities overall, but might be associated with particular vascular patterns of damage to the developing brain that could predispose to a hydranencephalic malformation.link_to_subscribed_fulltex

    Malignant mixed Mullerian tumors of the uterus

    Objective: To review the prognostic factors of Chinese women with mixed Mullerian tumors of the uterus. Method. A retrospective review of 21 cases of malignant mixed Mullerian tumors of the uterus treated during the 10-year period from 1980 to 1990. Results: All patients except one were postmenopausal. The incidence of previous pelvic irradiation was 9.5%. The most common presenting symptom was abnormal vaginal bleeding. One-third of patients yielded an abnormal cervical smear. Treatment included surgery, chemotherapy and radiotherapy in the majority of patients. Prognosis was poor with only three long-term survivors, all with stage-I homologous tumors with superficial myometrial invasion. The survival rate for stage-I and -II disease at 2 years was 50% and for more advanced disease extending beyond the uterus was 0%. The survival rate for all stages at 5 years was 14.3%, and the cumulative probability of survival at 5 years was 0.165. Conclusion: The most important prognostic factors appear to be the extent of tumor involvement at the time of diagnosis and the depth of myometrial invasion.link_to_subscribed_fulltex

    No full text
    Intravenous leiomyomatosis is considered to be a rare neoplastic disease usually arising from uterine fibromyomata, but its true incidence may be under-recognized. Mortalities from this condition are usually the result of intracardiac involvement. A case report of successful treatment of intravenous leiomyomatosis with intracardiac extension is presented, together with a review of the existing literature concerning this rare condition.link_to_subscribed_fulltex
