Summary
Clinical identification of breech presentation in the third trimester is only 57.1% accurate. Accuracy depends on the individual provider, not gestational age or maternal body mass index.
Area of Science:
- Obstetrics and Gynecology
- Fetal Medicine
- Diagnostic Accuracy
Background:
- Accurate determination of fetal presentation is crucial for optimal prenatal care and delivery planning.
- Breech presentation, where the fetus is positioned buttocks or feet first, requires specific management strategies.
Purpose of the Study:
- To assess the accuracy of clinical methods in identifying breech presentation during the third trimester.
- To identify factors influencing the accuracy of clinical breech presentation diagnosis.
Main Methods:
- Prospective study of 311 third-trimester patients.
- Clinical assessment of fetal presentation followed by ultrasound confirmation.
- Measurement of amniotic fluid volume, maternal BMI, and abdominal wall thickness.
Main Results:
- Overall accuracy of clinical breech presentation identification was 57.1% (28 out of 49).
- Gestational age, maternal BMI, and abdominal wall thickness did not significantly affect diagnostic accuracy.
- Significant variability in accuracy was observed among different examiners.
Conclusions:
- Clinical assessment of breech presentation has limited accuracy in the third trimester.
- Accuracy is primarily dependent on the individual healthcare provider's skill, not maternal or fetal factors like BMI or gestational age.

Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
