The Smallest of the Small: The smallest baby ever to survive ( 280g, 25 cm length) is now 14 years old. How's she doing? A letter to the editor (subscription required) to the New England Journal of Medicine says just great:
At two years of age, our patient had a Mental Development Index score of 86 (normal range, 84 to 116) on the Bayley Scales of Infant Development and was walking independently. Toilet training took place at three years of age. At five years of age, her visual acuity was 20/200 (in the right eye) and 20/100 (in the left) and was corrected with eyeglasses. Her only hospitalization was at four years of age, for pneumonia. She continues to have reactive airway disease. She started kindergarten at six years of age. A workup for failure to thrive and short stature at three and nine years of age, respectively, revealed no abnormalities. Menarche occurred at 13 years of age. She attends a regular school and has a cumulative grade-point average of 3.70 (of a possible 4.00) for the previous eight years. Since her birth, she has gained an average of 1.8 kg in weight and 9.7 cm in height annually. The 50th percentile for weight and height for girls at the age of 14 years are 50 kg and 163 cm, respectively. Despite her present weight of 25.4 kg and height of 136.5 cm, no psychosocial maladaptations have been reported. The results of her high-school entrance examinations were in the 83rd percentile nationally.
