Trend and causes of maternal death, stillbirth and neonatal death over seven decades in Hong Kong

Background: Reducing maternal and perinatal mortality is a global objective. Hong Kong is a city with low maternal and perinatal mortality but little is known about the trend and causes of these deaths in this high-income city. We analyzed the maternal death, stillbirth and neonatal death since 1946 in Hong Kong. Methods: Data were extracted from vital statistics, based on the number of registered deaths and births, provided by the Department of Health, the Government of the HKSAR. The annual change rate of mortality was evaluated by regression analysis. Contextual factors were collected to assess the association with mortality. Findings: Between 1946 and 2017, the stillbirth rate (per 1,000 total births) reduced from 21·5 to 2·4; early and late neonatal deaths (per 1,000 live births) reduced from 14·1 and 18·1 to 0·7 and 0·4 in 2017, respectively. The maternal mortality ratio (per 100,000 live births) declined from 125 to 1·8. The causes of maternal and perinatal deaths were available since 1981 and 1980 respectively. The leading causes of death were thromboembolism (37·0%) and obstetric haemorrhage (30·4%) for maternal death; congenital problem (30·1%) and prematurity (29·0%) for neonatal death. No data on causes of stillbirth were available. No specific shift of pattern was observed in the causes of maternal and neonatal death with time. There were no cases of maternal death due to sepsis and only 2 cases (2·2%) of maternal deaths due to indirect cause. Interpretation: The maternal and perinatal death have reduced significantly in Hong Kong and maintained at the lowest level globally. Indirect maternal death and sepsis were unusual causes of maternal deaths. Use of ICD-PM stillbirth classification, setting up a maternal death confidential enquiry and adding pregnancy checkbox could be the next step to identify and categorize hidden burden.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

Persistence of back pain symptoms after pregnancy and bone mineral density changes as measured by quantitative ultrasound - a two year longitudinal follow up study

<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/cm²; 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/cm²; 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

Avaliação da lordose lombar e sua relação com a dor lombopélvica em gestantes

O objetivo deste trabalho foi avaliar a magnitude da lordose lombar, sua influência na dor lombopélvica e a qualidade de vida em gestantes. Para tal, foi realizado um estudo com 20 mulheres não gestantes (C) e 13 gestantes ao longo dos trimestres gestacionais (G1, G2 e G3). Todas as mulheres foram submetidas à avaliação inicial para registro dos dados pessoais, hábitos de vida, antecedentes pessoais, uso de medicamentos, história ginecológica e obstétrica. Posteriormente, as voluntárias do grupo controle foram avaliadas uma vez e as gestantes foram avaliadas em três momentos distintos, no 10, 20 e 30 trimestres gestacionais. A avaliação do grau de lordose lombar foi realizada por meio de técnica fotogramétrica; a avaliação de locais de dor, o tipo de dor e sua intensidade foram feitas por meio do Questionário McGill de dor; e a avaliação da qualidade de vida foi feita pelo Questionário WHOQOL-bref. Neste trabalho, não foi possível observar padrão de alteração da curvatura lombar no decorrer da gestação. Também não foi observada relação entre a curvatura lombar e a dor lombopélvica relacionada à gestação.The purpose of this study was to evaluate the magnitude of lumbar lordosis, its influence on lumbopelvic pain and quality of life in pregnant women. To this end, a study was done with 20 non-pregnant women (C) and 13 pregnant women during the trimesters of pregnancy (G1, G2 and G3). All women underwent initial assessment for registration of personal data, lifestyle, personal history, medications, gynecological and obstetric history. Later, the volunteers in the control group were evaluated once and pregnant women were evaluated at three different times, the first, second and third trimesters of pregnancy. The evaluation of the degree of lumbar lordosis was performed by a photogrammetric technique. The assessment of points/places of pain, the kind of pain and its intensity were made by McGill Pain Questionnaire, and the quality of life assessment was made by WHOQOL-bref. In this study, it was not possible to observe a pattern of change in lumbar curvature during pregnancy. There was also no relationship between lumbar curvature and lumbopelvic pain related to pregnancy

The association between maternal smoking and fetal hydranencephaly

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

Intravenous leiomyomatosis with intracardiac involvement

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
