The Incidence of Birthmarks in the Neonate

Jacobs, Alvin H., Walton, Robert G.·1976·Pediatrics

Abstract

The presence of various types of birthmarks was determined in 1,058 newborn infants under 72 hours of age. Of these, 79.5% were white, 6.2% were black, 11.2% were ladinos, and 2.6% were Asiatic. Mongol spots were present in 9.6% of the white babies, 95.5% of the black babies, 81% of the Asiatic babies, and 70.1% of ladino infants. Pigmented lesions were present in 42 (4%) of the infants. Biopsies obtained in 34 (3.2%) revealed that only one-third (11) of these were melanocytic nevi. Salmon patches were present in 40.3% of the infants, recognizable early strawberry marks in 2.6%, and port-wine stains in 0.3%. In addition to birthmarks, it was determined that 30.3% of the 508 babies examined at one of the two hospitals had toxic erythema of the newborn.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
