Summary
This review examines long birth intervals in twin and triplet births, including a multicentre study on gestational and survival data for 35 multiple births. It also covers twin communication, chorionicity, and hemihypertrophy in twins.
Area of Science:
- Reproductive Medicine
- Genetics
- Neonatology
Background:
- Unusually long birth intervals between multiple births present unique clinical challenges.
- Existing research on managing these cases and associated twin-specific phenomena is diverse.
Purpose of the Study:
- To review current research on extended birth intervals in twin and triplet gestations.
- To evaluate treatment strategies for mothers delivering one twin fetus.
- To present findings from recent twin studies on communication, chorionicity, and genetic conditions.
Main Methods:
- Literature review of studies on long birth intervals in multiple gestations.
- Analysis of a multicentre study including gestational and survival data for 35 multiple birth sets.
- Review of three recent twin-specific studies and anecdotal accounts.
Main Results:
- A multicentre study provided gestational and survival data for 35 multiple birth sets.
- Recent twin studies explored inter-twin communication's effect on longevity, dizygous twins with a single chorion, and hemihypertrophy discordance in MZ twins.
- Anecdotal accounts offered insights into twin-related phenomena.
Conclusions:
- The review synthesizes current knowledge on managing long birth intervals in multiple births.
- It highlights diverse aspects of twin research, from clinical management to genetic and behavioral observations.
- Further investigation into these unique obstetric and developmental scenarios is warranted.
