Amniotic band syndrome and/or limb body wall complex: split or lump
1Department of Reproductive Biology, All India Institute of Medical Sciences, New Delhi, India.
This study examines clinicopathologic features of amniotic band syndrome/limb body wall complex. Etiologies including amniotic, vascular, or genetic disruption may explain these complex congenital anomalies.
Area of Science:
- Medical Genetics
- Developmental Biology
- Pathology
Background:
- Amniotic band syndrome/limb body wall complex are rare congenital anomalies.
- Diagnosis relies on specific combinations of craniofacial clefts, limb body wall defects, and amniotic band attachment.
Purpose of the Study:
- To investigate the clinicopathologic characteristics of amniotic band syndrome/limb body wall complex.
- To explore potential etiopathogenetic mechanisms.
Main Methods:
- Retrospective analysis of six cases with clinicopathologic evaluation.
- Histological examination of amniotic bands and umbilical cords.
- Literature review for etiopathogenetic insights.
Main Results:
- Four stillborn cases exhibited severe internal and external malformations.
- Two live-born cases presented with facial and limb defects.
- Histology revealed fibroconnective tissue and neuroectodermal elements in bands; abnormal umbilical cord vasculature.
Conclusions:
- Amniotic disruption, vascular disruption, or genetic disruption, individually or combined, may cause these syndromes.
- The study proposes an etiopathogenetic model for these complex conditions.

Aneurysm I: Introduction
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
