An evaluation of systematic and random errors in ultrasound estimated fetal weight during serial ultrasound.

Introduction: Ultrasound estimated fetal weight is increasingly being used in the monitoring of fetal growth. Large systematic and random errors in estimated fetal weight have been reported; these may have an impact on the accuracy of fetal growth monitoring. The aim of this study was to attempt to evaluate these systematic and random errors by analysis of serial ultrasound data.

Implementing placental-growth-factor (PLGF) measurements in suspected pre-eclampsia----Challenges in clinical practice.

Objectives: As a part of NHS' Innovation and Technology Payment programme (ITP), pregnant women were offered Placental Growth Factor (PLGF)-based testing to help rule out pre-eclampsia (PET) - a serious condition that affects approximately 2.3% of the female population. The study was aimed to evaluate the implementation of PLGF-based testing at United Lincolnshire Trust Hospitals (ULHT).

Expanding perfusion across disciplines: the use of thrombelastography technology to reduce risk in an obstetrics patient with Gray Platelet Syndrome--a case study.

It is important that our speciality continues to push its boundaries. Our perfusion team has invested time lecturing to non-cardiac specialties about perfusion-led technology. This resulted in working closely with the obstetrics team to treat a pregnant patient with the bleeding disorder Gray Platelet Syndrome.

Spontaneous breakage and expulsion of a stem fragment of levonorgestrel intrauterine system (Mirena) following duplicate insertion.

Background: Removal and changing an intra-uterine device (IUD) involves good history taking, a proper examination and appropriate experience in fitting IUDs.

Case: We present a case of a woman who had two insertions of the levonorgestrel intrauterine system (LNG-IUS) which was diagnosed only at hysteroscopy when she presented with the spontaneous expulsion of a vertical stem of one of the devices.

Conclusion: This is a unique case where two LNG-IUS were inserted in error and hence it teaches the clinicians the importance of good training and being aware of the possibility of the missing thread which deserves further investigations especially when such cases are encountered in a busy general practice.
