The aim of this study was to provide a temporal-spatial reference of adverse pregnancy outcomes (APO) and examine whether endometriosis promotes APO in the same population. Among the 31?068 women who had a pregnancy between 1997 and 2008 in Eastern Townships of Canada, 6749 (21.7%) had APO. These APO increased significantly with maternal age and over time (r(2?)=?0.522, p?=?0.008); and were dominated by preterm birth (9.3%), pregnancy-induced hypertension (8.3%) including gestational hypertension (6.5%), low birth weight (6.3%), gestational diabetes (3.4%), pregnancy loss (2.2%) including spontaneous abortion (1.5%) and stillbirth (0.6%), intrauterine growth restriction (2.1%) and preeclampsia (1.8%). Among the 31?068 pregnancies, 784 (2.5%) had endometriosis and 183 (23.3%) had both endometriosis and APO. Endometriosis has been shown to increase the incidence of fetal loss (OR?=?2.03; 95% CI?=?1.42-2.90, p?
The objective of the study was to determine completeness of 24-hour urine collection in pregnancy.
This was a retrospective laboratory/chart review of 24-hour urine collections at British Columbia Women's Hospital. Completeness was assessed by 24-hour urinary creatinine excretion (UcreatV): expected according to maternal weight for single collections and between-measurement difference for serial collections.
For 198 randomly selected pregnant women with a hypertensive disorder (63% preeclampsia), 24-hour urine collections were frequently inaccurate (13-54%) on the basis of UcreatV of 97-220 micromol/kg per day (11.0-25.0 mg/kg per day) or 133-177 micromol/kg per day (15.1-20.1 mg/kg per day) of prepregnancy weight (respectively). Lean body weight resulted in more inaccurate collections (24-68%). The current weight was frequently unavailable (28%) and thus not used. For 161 women (81% proteinuric) with serial 24-hour urine levels, a median [interquartile range] of 11 [5-31] days apart, between-measurement difference in UcreatV was 14.4% [6.0-24.9]; 40 women (24.8%) had values 25% or greater, exceeding analytic and biologic variation.
Twenty-four hour urine collection is frequently inaccurate and not a precise measure of proteinuria or creatinine clearance.
This study aims to make an account of the children born following transplantation of frozen-thawed ovarian tissue worldwide with specific focus on the perinatal outcome of the children. Furthermore, perinatal outcome of seven deliveries (nine children) from Denmark is reported.
PubMed was searched for papers of deliveries resulting from ovarian tissue cryopreservation (OTC). Seven women underwent OTC prior to chemotherapy. Four of these women still had low ovarian function and had tried to conceive. They therefore had tissue autotransplanted to augment their fertility. The other three women had developed premature ovarian insufficiency (POI) after the end of treatment.
Worldwide, approximately 95 children have been born or will be born in the near future from OTC, including these 9 new children. Information on the perinatal outcome was found on 40 children. The mean gestational age was 39 weeks and the mean birth weight was 3168 g of the singleton pregnancies, which is within internationally recognized normal standards. Furthermore, half the singletons resulted from natural conception and all twins resulted from in vitro fertilization treatment. All seven Danish women became pregnant within 1-3 years after transplantation. They gave birth to nine healthy children.
The data is reassuring and further suggests that cryopreservation of ovarian tissue is becoming an established fertility preservation method. The seven Danish women reported in this study were all in their early thirties when OTC was performed. Most other reported cases were in the women's twenties. This suggests that the follicular pool in the thirties is large enough and sufficient to sustain fertility.
Abdominal pregnancy resulting in a liveborn infant is an obstetric rarity in Denmark. A case is reported and four cases reported during the past 20 years are reviewed. In the present case, the diagnosis of extrauterine pregnancy was not established in advance. The infant, a full-term boy weighing 3,650 g, was delivered transplacentally by Caesarean section during epidural analgesia. The placenta was adherent to the intestines and was left in the abdomen for spontaneous resorption but was expelled gradually through an amnio-percutaneous fistula over a period of three months. The infant did not present any evidence of congenital abnormalities.
OBJECTIVE--To evaluate the outcome of pregnancy in Finnish women after the accident at the Chernobyl nuclear power plant on 26 April 1986. DESIGN--Geographic and temporal cohort study. SETTING--Finland divided into three zones according to amount of radioactive fallout. SUBJECTS--All children who were exposed to radiation during their fetal development. Children born before any effects of the accident could be postulated--that is, between 1 January 1984 and 30 June 1986--served as controls. INTERVENTIONS--Children were divided into three temporal groups: controls, children who were expected to be born in August to December 1986, and children who were expected to be born in February to December 1987. They were also divided, separately, into three groups according to the three geographic zones. END POINT--Incidence of congenital malformations, preterm births, and perinatal deaths. MEASUREMENTS AND MAIN RESULTS--There were no significant differences in the incidence of malformations or perinatal deaths among the three temporal and three geographic groups. A significant increase in preterm births occurred among children who were exposed to radiation during the first trimester whose mothers lived in zones 2 and 3, where the external dose rate and estimated surface activity of caesium-137 were highest. CONCLUSIONS--The results suggest that the amount of radioactive fallout that Finnish people were exposed to after the accident at Chernobyl was not high enough to cause fetal damage in children born at term. The higher incidence of premature births among malformed children in the most heavily polluted areas, however, remains unexplained.

OBJECTIVE: To evaluate the effect of acupuncture on reproductive outcome in patients treated with IVF/intracytoplasmic sperm injection (ICSI). One group of patients received acupuncture on the day of ET, another group on ET day and again 2 days later (i.e., closer to implantation day), and both groups were compared with a control group that did not receive acupuncture. DESIGN: Prospective, randomized trial. SETTING: Private fertility center. PATIENT(S): During the study period all patients receiving IVF or ICSI treatment were offered participation in the study. On the day of oocyte retrieval, patients were randomly allocated (with sealed envelopes) to receive acupuncture on the day of ET (ACU 1 group, n = 95), on that day and again 2 days later (ACU 2 group, n = 91), or no acupuncture (control group, n = 87). INTERVENTION(S): Acupuncture was performed immediately before and after ET (ACU 1 and 2 groups), with each session lasting 25 minutes; and one 25-minute session was performed 2 days later in the ACU 2 group. MAIN OUTCOME MEASURE(S): Clinical pregnancy and ongoing pregnancy rates in the three groups. RESULT(S): Clinical and ongoing pregnancy rates were significantly higher in the ACU 1 group as compared with controls (37 of 95 [39%] vs. 21 of 87 [26%] and 34 of 95 [36%] vs. 19 of 87 [22%]). The clinical and ongoing pregnancy rates in the ACU 2 group (36% and 26%) were higher than in controls, but the difference did not reach statistical difference. CONCLUSION(S): Acupuncture on the day of ET significantly improves the reproductive outcome of IVF/ICSI, compared with no acupuncture. Repeating acupuncture on ET day +2 provided no additional beneficial effect.
OBJECTIVE: To investigate acupuncture treatment during labour with regard to pain intensity, degree of relaxation and outcome of the delivery. DESIGN: Randomised controlled trial. SETTING: Delivery ward at a tertiary care centre hospital in Sweden. POPULATION: Ninety parturients who delivered during the period April 12, 1999 and June 4, 2000. METHODS: Forty-six parturients were randomised to receive acupuncture treatment during labour as a compliment, or an alternative, to conventional analgesia. MAIN OUTCOME MEASURES: Assessments of pain intensity and degree of relaxation during labour, together with evaluation of delivery outcome. RESULTS: Acupuncture treatment during labour significantly reduced the need of epidural analgesia (12% vs 22%, relative risk [RR] 0.52, 95% confidence interval [CI] 0.30 to 0.92). Parturients who received acupuncture assessed a significantly better degree of relaxation compared with the control group (mean difference -0.93, 95% CI -1.66 to -0.20). No negative effects of acupuncture given during labour were found in relation to delivery outcome. CONCLUSIONS: The results suggest that acupuncture could be a good alternative or complement to those parturients who seek an alternative to pharmacological analgesia in childbirth. Further trials with a larger number of patients are required to clarify if the main effect of acupuncture during labour is analgesic or relaxing.
OBJECTIVE--To establish guidelines for the management of a pregnancy that is complicated by acute appendicitis. DESIGN--Retrospective study. SETTING--University Hospital, Copenhagen, Denmark. SUBJECTS--16 patients operated on for symptoms of acute appendicitis during the 15 year period 1974-1988. RESULTS--In 12 patients (75%) the diagnosis was confirmed histologically. The signs and symptoms were classic, and three patients had contractions. One fetus died, in a patient with appendicitis complicated by intraperitoneal abscess. In all uncomplicated cases the pregnancy proceeded to term and the deliveries were normal. CONCLUSIONS--Pregnancy should not deter a surgeon from removing an appendix, once the diagnosis is suspected; no pregnancy was affected by removal of a normal appendix. We recommend that prophylactic antibiotics and tocolytic drugs be given in all cases. Simultaneous caesarean section should be done only if there are obstetric indications.
To determine the antecedent factors, morbidity, and mortality associated with disseminated intravascular coagulation (DIC) in a Nova Scotia tertiary maternity hospital over a 30-year period.
Cases of DIC were identified from the Nova Scotia Atlee Perinatal Database for the years 1980 to 2009 and the hospital charts reviewed. The clinical diagnosis of DIC was confirmed or refuted using a combination of the International Society of Thrombosis and Haemostasis scoring system and an obstetrical DIC-severity staging system. The cause of DIC was determined from chart review. Maternal outcomes included massive transfusion (= 5 units), hysterectomy, admission to ICU, acute tubular necrosis (ATN) requiring dialysis, and death. Neonatal outcomes included Apgar scores, birth weight, NICU admission, and death. Treatment of DIC was assessed by blood products administered, postpartum hemorrhage management, and laboratory measurements.
There were 49 cases of DIC in 151 678 deliveries (3 per 10,000) over the 30 years. Antecedent causes included placental abruption (37%), postpartum hemorrhage or hypovolemia (29%), preeclampsia/HELLP (14%), acute fatty liver (8%), sepsis (6%), and amniotic fluid embolism (6%). The associated maternal morbidity included transfusion = 5 units (59%), hysterectomy (18%), ICU admission (41%), and ATN requiring dialysis (6%). There were three maternal deaths, giving a case fatality rate of 1 in 16. The perinatal outcomes included stillbirth (25%), neonatal death (5%), and NICU admission (72.5%).
Obstetrical DIC is an uncommon condition associated with high maternal and perinatal morbidity and mortality. Prompt recognition and treatment with timely administration of blood products is crucial in the management of this life-threatening disorder.
