Perinatal outcomes in pregnancies complicated by acute pancreatitis.

OBJECTIVES: Acute pancreatitis is a rare condition that can be associated with significant complications. The objective of this study is to evaluate the maternal and newborn outcomes associated with acute pancreatitis in pregnancy. METHODS: A retrospective cohort study using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from the United States was performed. All pregnant patients with acute pancreatitis were identified using International Classification of Disease-9 coding from 1999 to 2015. The effect of acute pancreatitis on maternal and neonatal outcomes in pregnancy was evaluated using multivariate logistic regression, while adjusting for baseline maternal characteristics. RESULTS: From 1999 to 2015, there were a total of 13,815,919 women who gave birth. There were a total of 14,258 admissions of women diagnosed with acute pancreatitis, including 1,756 who delivered during their admission and 12,502 women who were admitted in the antepartum period and did not deliver during the same admission. Acute pancreatitis was associated with increased risk of prematurity, OR 3.78 (95% CI 3.38-4.22), preeclampsia, 3.81(3.33-4.36), postpartum hemorrhage, 1.90(1.55-2.33), maternal death, 9.15(6.05-13.85), and fetal demise, 2.60(1.86-3.62) among women diagnosed with acute pancreatitis. Among women with acute pancreatitis, delivery was associated with increased risk of requiring transfusions, 6.06(4.87-7.54), developing venous thromboembolisms, 2.77(1.83-4.18), acute respiratory failure, 3.66(2.73-4.91), and disseminated intravascular coagulation, 8.12(4.12-16.03). CONCLUSIONS: Acute pancreatitis in pregnancy is associated with severe complications, such as maternal and fetal death. Understanding the risk factors that may lead to these complications can help prevent or minimize them through close fetal and maternal monitoring.

Effects of Surgical Delay Due to COVID-19 on Women Requiring Emergency Gynaecological Surgery.

In response to the coronavirus-19 (COVID-19) pandemic, the McGill University Health Centre introduced protocols to protect health care workers during emergency surgeries. These included waiting for a COVID-19 test result or waiting 20 minutes after aerosol-inducing procedures before proceeding with surgery. The following brief communication describes the impact of surgical delay on the outcomes of 3 emergency gynaecologic procedures: dilatation and curettage, laparoscopic salpingectomy, and laparoscopic cystectomy and detorsion. Our results show that delays associated with COVID-19 protocols did not negatively impact patients undergoing these surgeries.

Spontaneous Uterine Rupture in a Multigravid Pregnant Woman with Unscarred Uterus on Chronic Steroid Use: A Case Report.

BACKGROUND: Uterine rupture in pregnancy is associated with severe maternal and fetal complications. Although it is a rare event, uterine rupture has been associated with certain risk factors. Glucocorticoids are known to weaken skeletal muscles; however, there have been no studies on the effects of chronic steroid use on the uterine myometrium. CASE: We present the case of a 40-year-old multigravid woman who experienced a posterior uterine wall rupture on an unscarred uterus. She was on chronic glucocorticoids for the treatment of psoriatic arthritis. We hypothesize that the catabolic effects of glucocorticoids on skeletal muscles also weakened the uterine myometrium, leading to a higher risk of uterine rupture. CONCLUSION: Uterine rupture may be associated with chronic use of corticosteroids. Identifying the different risk factors for uterine rupture can lead to more prompt diagnosis and management of uterine rupture, resulting in better maternal and fetal outcomes.

Beyond the Pfannenstiel: Minimally invasive Laparotomy Incisions for Maximum Exposure.

Although gynaecologists may be most familiar with the Pfannenstiel and midline laparotomy incisions, the Cherney and Maylard incisions are two alternative transverse abdominal incisions with unique advantages. Both provide superior pelvic exposure compared with the Pfannenstiel incision and offer significant benefits over a midline incision, such as decreased postoperative pain and improved wound healing. These incisions can be used for a multi-fibroid uterus, large pelvic masses, endometriosis, or when access to the retropubic or other pelvic spaces is needed. This video reviews surgically relevant anatomy of the anterior abdominal wall and provides a stepwise approach for performing both the Maylard and Cherney incisions using narrated illustrations and video footage. Surgical technique and anatomical considerations are highlighted throughout the video. This educational tool can be used as a reference for gynaecologists when performing these less commonly used incisions. When a laparotomy is indicated, the Maylard or Cherney incision can be considered as alternative approaches to a midline laparotomy in gynaecologic surgery, as both result in less postoperative morbidity while still providing excellent pelvic access.

A Case Series of Patients with Large Uterine Fibroids and Venous Thromboembolisms.

OBJECTIVE: The purpose of this case series is to identify the clinical characteristics of women with uterine fibroids who developed venous thromboembolisms (VTE) and possible risk factors for the development of VTE in this group. DATA SOURCES: We conducted a systematic search of the Medline, Embase, Cochrane and Scopus databases to retrieve case reports and case series that describe women with an enlarged uterus and VTE. The databases were searched up to August 2019. STUDY SELECTION: A total of 1485 articles were identified by a librarian. All case series and case reports that reported uterine weight and size of the fibroids were included. DATA EXTRACTION AND SYNTHESIS: A total of 27 articles were included, describing 35 patients who developed VTE in the presence of uterine fibroids. On average, the uterus measured 22.9 ± 5.0 weeks gestational age and occupied a volume of 2715 cm3 (interquartile range 1296.3-3878.8) on imaging. Two-thirds (60%) of VTEs occurred on the left side, and 87% showed signs of venous compression on imaging. Most patients (89%) required surgical management to relieve the compression caused by the enlarged uterus. CONCLUSION: VTE in cases of large uterine leiomyomas can be associated with mechanical compression, which requires surgical management to relieve compression. There is an obvious increased risk of VTE in patients with venous stasis secondary to uterine compression; however, there is no current evidence evaluating the use of anticoagulation in such patients. Further research is required to determine the role of prophylactic anticoagulation in reducing the risk of VTE in high-risk patients with large uterine fibroids.

Maternal and neonatal outcomes in women with disorders of lipid metabolism.

OBJECTIVES: The effects of lipid metabolism disorders (LMD) on pregnancy outcomes is not well known. The purpose of this study is to evaluate the impact of LMD on maternal and fetal outcomes. METHODS: Using the Healthcare Cost and Utilization Project - National Inpatient Sample from the United States, we carried out a retrospective cohort study of all births between 1999 and 2015 to determine the risks of complications in pregnant women known to have LMDs. All pregnant patients diagnosed with LMDs between 1999 and 2015 were identified using the International Classification of Disease-9 coding, which included all patients with pure hypercholesterolemia, pure hyperglyceridemia, mixed hyperlipidemia, hyperchylomicronemia, and other lipid metabolism disorders. Adjusted effects of LMDs on maternal and newborn outcomes were estimated using unconditional logistic regression analysis. RESULTS: A total of 13,792,544 births were included, 9,666 of which had an underlying diagnosis of LMDs for an overall prevalence of 7.0 per 10,000 births. Women with LMDs were more likely to have pregnancies complicated by diabetes, hypertension, and premature births, and to experience myocardial infarctions, venous thromboembolisms, postpartum hemorrhage, and maternal death. Their infants were at increased risk of congenital anomalies, fetal growth restriction, and fetal demise. CONCLUSIONS: Women with LMDs are at significantly higher risk of adverse maternal and newborn outcomes. Prenatal counselling should take into consideration these risks and antenatal care in specialized centres should be considered.

Influence of stage and grade of breast cancer on fertility preservation outcome in reproductive-aged women.

RESEARCH QUESTION: Does breast cancer spread and aggressiveness affect fertility-preservation results? DESIGN: Retrospective cohort study of women with breast cancer undergoing fertility-preservation treatment. INCLUSION CRITERIA: age 18-38 years and use of gonadotrophin releasing hormone antagonist protocol; exclusion criteria: recurrent cancer, previous oncological treatment, previous ovarian surgery and known ovarian pathology. Stimulation cycle outcomes of women with low-stage breast cancer were compared with those with high-stage disease. Patients with low-grade (G1-2) were compared with those with high-grade (G3) malignancies. PRIMARY OUTCOME: total number of mature oocytes; secondary outcomes: oestradiol level and number of follicles wider than 14 mm on the day of trigger, number of retrieved oocytes and cryopreserved embryos. RESULTS: The final analysis included 155 patients. Patients with high-grade tumours (n = 80; age 32 years [28-35]) had significantly lower number of mature oocytes compared with patients with low-grade cancer (n = 75; age 32 years [28-35]; seven mature oocytes [4-10] versus 13 mature oocytes [7-17]; P = 0.0002). The number of cryopreserved embryos was also lower in the high-grade group (three [2-5] versus five [3-9]; P = 0.02). Stage-based analysis revealed a similar number of mature oocytes in high-stage (n = 73; age 32 years [28-35]) compared with low-stage group (n = 82; age 33 years [28-35]; eight mature oocytes [4-13] versus nine mature oocytes [7-15]; P = 0.06). CONCLUSIONS: High-grade breast cancer has a negative effect on total number of mature oocytes and cryopreserved embryos.

Maternal and fetal outcomes in pregnancies with long-term corticosteroid use.

PURPOSE: Long-term corticosteroids are administered in pregnant patients with an array of autoimmune and inflammatory disorders. Our objective is to determine whether long-term corticosteroid use is associated with increased maternal and neonatal adverse outcomes. MATERIALS AND METHODS: We performed a retrospective cohort study using the Healthcare Cost and Utilization Project-national Inpatient Sample from the USA. All pregnant patients on long-term corticosteroids were identified using International Classification of Disease-9 coding from 2003 to 2015. The effect of long-term corticosteroid use on maternal and neonatal outcomes was evaluated using multivariate logistic regression. RESULTS: Out of the 10,491,798 births included in our study, 3999 were among women with long-term use of steroids, for an overall prevalence of 38 per 100,000 births. There was a steady increase in chronic steroid use from 2 to 81 per 100,000 births over the 13-year study period (p < .0001). Women on long-term steroids were more likely to have pregnancies complicated by preeclampsia, 1.72 (1.30-2.29) and were at greater risk of preterm premature rupture of membranes, 1.63 (1.01-2.44), pyelonephritis, 4.81 (1.18-19.61), and venous thromboembolisms, 2.50 (1.32-4.73). Neonates born from mothers on long-term steroids were more likely to suffer from prematurity, 1.51 (1.13-2.05), and lower weight for gestational age, 2.10 (1.34-3.30). CONCLUSION: Long-term corticosteroids use in pregnancy is associated with maternal and fetal adverse outcomes. These patients would benefit from close follow-up throughout their pregnancy to minimize complications.

Effects of methylphenidate on acute math performance in children with attention-deficit hyperactivity disorder.

OBJECTIVE: Examine the short-term (acute) effects of methylphenidate (MPH) on math performance in children with attention-deficit hyperactivity disorder (ADHD) and what factors predict improvement in math performance. METHOD: One hundred ninety-eight children with ADHD participated in a double-blind, placebo-controlled, randomized crossover MPH trial. Math response to MPH was determined through administration of math problems adjusted to their academic level during the Restricted Academic Situation Scale (RASS). Student t tests were conducted to assess change in math performance with psychostimulants. Correlation between change on the RASS and change on the math performance was also examined. Linear regression was performed to determine predictor variables. RESULTS: Children with ADHD improved significantly in their math with MPH (P < 0.001). The degree of improvement on the RASS (which evaluates motor activity and orientation to task) and on math performance on MPH was highly correlated. A child's age at baseline and Wechsler Individual Achievement Test (WIAT)-Numerical Operations standard scores at baseline accounted for 15% of variances for acute math improvement. CONCLUSIONS: MPH improves acute math performance in children with ADHD. Younger children with lower math scores (as assessed by the WIAT) improved most on math scores when given psychostimulants. CLINICAL TRIAL REGISTRATION NUMBER: NCT00483106.

Objectif : Examiner les effets à court terme (aigus) du méthylphénidate (MPH) sur la performance en mathématique chez des enfants souffrant du trouble de déficit de l'attention avec hyperactivité (TDAH), et quels facteurs prédisent une amélioration de la performance en math. Méthode : Cent quatre-vingt-dix-huit enfants souffrant du TDAH ont participé à un essai de MPH croisé, randomisé, à double insu et contrôlé avec placebo. La réponse du MPH en math a été déterminée par l'administration de problèmes de math ajustés à leur niveau scolaire durant la Restricted Academic Situation Scale (RASS). Les tests t de Student ont été menés afin d'évaluer le changement de la performance en math avec les psychostimulants. La corrélation entre le changement à la RASS et le changement de la performance en math a aussi été examinée. Une régression linéaire a été exécutée pour déterminer les variables prédictives. Résultats : Les enfants souffrant du TDAH se sont améliorés significativement en math avec le MPH (P < 0,001). Le degré d'amélioration à la RASS (qui évalue l'activité motrice et l'orientation dans les tâches) et dans la performance en math avec MPH était hautement corrélé. L'âge de l'enfant au départ et les scores normaux au départ au Wechsler Individual Achievement Test (WIAT) ­ des opérations numériques représentaient 15 % des variances d'amélioration aiguë en math. Conclusions : Le MPH améliore la performance aiguë en mathématique chez les enfants souffrant du TDAH. Les enfants plus jeunes qui ont de moins bons scores en math (évalué par le WIAT) ont surtout amélioré leurs scores en math lorsqu'ils ont reçu des psychostimulants. Numéro d'enregistrement d'essai clinique : NCT00483106.
