The Kinderhook Plates Readers should note that today, these items are either lost or verified forgeries. The Manual’s Kinderhook section defends Joseph Smith’s partial translation. Its editors suggest that the testimony of Wilbur Fugate, who admitted creating the plates as a hoax, must be false, primarily because only he out of the three “discoverers” blew the whistle on the forgery. Moreover, the editors express suspicion of Fugate because he waited 36 years to confess his part in the supposed hoax.

Pettker, MD; James D. Goldberg, MD; and Yasser Y. This document reflects emerging clinical and scientific advances as of the date issued and is subject to change. The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date EDD should be determined, discussed with the patient, and documented clearly in the medical record.

Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.
