RESUMEN
Introduction: There is increasing evidence demonstrating the safety and benefits of physical activity (PA) in uncomplicated pregnancies. Literature has shown that pregnant women around the world do not engage in adequate exercise. This study aims to assess the current practices of exercise among pregnant women in Singapore, determine the proportion of women meeting different PA targets and evaluate the factors influencing the practice of exercise. Methods: In this cross-sectional study, pregnant women in different trimesters of pregnancy from KK Women's and Children's Hospital and Singapore General Hospital were surveyed. Information regarding patient demographics, attitudes and perceptions of exercise, and practice of exercise was collected. The International Physical Activity Questionnaire (IPAQ) was used to determine the amount of PA. Results: A total of 201 pregnant women aged 20-44 years were surveyed. Almost all (99.0%) participants thought that exercise was beneficial in pregnancy. Only 31.6% of them engaged in any moderate or vigorous leisure-time PA (LTPA) and they were active for a median of 120 min/week. Only 12.6% of the pregnant women met the national recommendations of at least 150 min of moderate exercise per week. The amount of total PA performed was lower among women in later trimesters of pregnancy and higher among working mothers. Conclusion: Although most Singaporean pregnant women perceived exercise as beneficial, the majority did not engage in PA. Most of the participants did not meet the international PA targets and recently published national guidelines. More can be done to promote the uptake of exercise in pregnancy and optimise metabolic management of pregnant women in Singapore.
RESUMEN
A colovaginal fistula (CVF) is an abnormal epithelialized connection between the colon and the vagina. It is a rare complication following gynaecology surgery and can significantly affect patients' quality of life. CVFs are commonly associated with diverticular disease and are usually seen in patients with a previous hysterectomy. We report an uncommon case of postsurgical CVF following vaginal hysterectomy with mesh-augmented pelvic floor repair, which was unrelated to diverticulitis. The patient was successfully managed by a multidisciplinary team with staged surgery.
RESUMEN
Hemoglobin (Hb) Bart's hydrops fetalis is the most severe form of α-thalassemia and is usually inherited in an autosomal recessive manner. We report a case of Hb Bart's hydrops fetalis due to uniparental disomy of chromosome 16. Antenatal screening showed a low maternal mean corpuscular volume (MCV), while paternal MCV was normal. The fetus was found to have a thickened nuchal translucency during first trimester screening for Down's syndrome. Mid-trimester fetal anomaly ultrasound scan showed fetal cardiomegaly with pericardial effusion, scalp edema, ascites and an elevated middle cerebral arterial peak systolic velocity (MCA PSV). Multiplex polymerase chain reaction (PCR) on DNA from amniocentesis showed that the fetus was homozygous for South East Asian (SEA) type 2 α-globin gene deletion. Chromosome microarray (CMA) showed two regions of absence of heterozygosity (AOH) on the terminal p and q arm of chromosome 16. The rare occurrence of Hb Bart's hydrops fetalis caused by maternal uniparental disomy should be considered in cases of fetal hydrops even in cases where paternal MCV is normal.
RESUMEN
Haemangioma of the retroperitoneal space is a rare benign capillary malformation, which can grow significantly in pregnancy due to the multiple associated cardiovascular changes. We herein describe the case of a pregnant woman with an extensive right retroperitoneal haemangioma extending from the level of the renal hilum, across the lateral anterior abdominal wall and into the thigh. We also highlight the challenges faced in the management of the patient's delivery process. To the best of our knowledge, this is the first case of such nature and severity described in the English literature.
