Quadruplets are at elevated physical risks at prenatal, perinatal, and postnatal levels, relative to twins. A brief review of this area is followed by discussion of a female quadruplet with three co-quadruplet brothers. Next, several timely twin research reports are examined. The topics include antenatal corticosteroids and twins' neonatal outcomes, the meaning of fatherhood in families with twins, what doppelgängers (look-alikes) reveal about physical and behavioral similarity, and monozygotic (MZ) co-twin discordance for asymmetric pigmented paravenous chorioretinal atrophy. A lawsuit involving alleged cheating on a medical school examination by identical twins is also reviewed. General interest stories cover opposite-sex twin Holocaust survivors, twin models at a Gucci fashion show, twins with different fathers, reunited female twins who entered the same convent, the death of an MZ female twin soldier during training, and the surgical separation of conjoined twins in Brazil.
四胞胎在产前、围产期和产后阶段相对于双胞胎来说，面临更高的身体风险。本文简要回顾了这一领域的研究，接着讨论了一位女性四胞胎和她的三位同卵四胞胎兄弟。接下来，本文还探讨了几项及时的双胞胎研究报告。这些报告的主题包括产前皮质激素与双胞胎新生儿结局、双胞胎家庭中父亲身份的意义、“二重身”（长得一样的人）揭示的身体和行为相似性、以及单卵双胞胎（MZ）异卵不合的不对称性色素性脉络膜视网膜萎缩。本文还回顾了一起涉及一对双胞胎在医学院考试中涉嫌作弊的诉讼案件。一些有趣的故事则涵盖了异性双胞胎大屠杀幸存者、古驰时装秀上的双胞胎模特、有不同父亲的双胞胎、进入同一女修道院的双胞胎姐妹、一名 MZ 女性双胞胎士兵在训练中死亡，以及巴西连体双胞胎的分离手术。
