Cognitive deficits in iron-deficient and iron-deficient anemic children.

Eighteen- to 60-month-old iron-deficient anemic children given iron therapy (n = 25) and a control group matched for mother's educational level showed no significant difference in mean mental development score at baseline. The control group's mean score was increased significantly over baseline score at 3 and 6 months and was significantly higher than the experimental group's mean score at 3 months. Although the experimental group demonstrated hematologic correction over 6 months, mean mental development score showed no significant improvement. Scores for an iron deficient not anemic group given iron (n = 22), despite complete hematologic correction over the six months of observation, and for its control group, did not change significantly. Baseline scores for an iron-deficient not anemic placebo group (n = 23) and for its control group were not significantly different. At 3 months the control group score had increased significantly, whereas that for the experimental group had not. When experimental and control subjects were matched on baseline mental development score, the control subjects experienced increases in scores over time, further confirming an impaired ability to improve scores with repeated testing in the experimental groups. Behavioral rating data (responsiveness to examiner, responsiveness to environment, and emotional tone) revealed significant differences between the iron-deficient anemic group and its control group at 3 and 6 months, with the control group rated more responsive, suggesting that iron deficiency, alone or in association with anemia, may have some lasting effect on behavior and development. Group differences were also found between the mean number of occurrences of multiple stressful events. Failure to show improvement in scores in the iron-deficient anemic group may reflect the fact that those children were less testable than were children in the control group, despite repeated testings, a theory supported by the infant behavior rating data. This may be related to some irreversible behavioral deficit or to an adverse environmental milieu (e.g., stress).

Posthemorrhagic hydrocephalus in the preterm infant.

Between 1969 and 1978 we treated 22 low birth weight infants for delayed onset posthemorrhagic hydrocephalus. All developed clinical signs of hydrocephalus after 2 weeks of age. The diagnosis was determined in 12 infants before August 1974, and they were treated by surgical placement of a shunt. In the ten infants born after September 1974, an attempt was first made to control the hydrocephalus with repeated lumbar puncture and diuretics prior to placing a shunt. In seven of the ten the hydrocephalus was successfully arrested by medical therapy alone. Follow-up assessments at 1 to 8 years of age were done on 18 infants. Two of the 12 treated by permanent shunts and three of six treated medically had an IQ score of 85 or greater. These results indicate a poor long-term outlook for the low birth weight infant who develops clinically overt hydrocephalus after intracranial bleeding.

Laryngeal mycosis fungoides.

Mycosis fungoides presented as a tumor of the arytenoid cartilage and epiglottis of the larynx of an 80-year-old female. The tumor was initially interpreted as an undifferentiated small cell malignant neoplasm and treated with radiation. Two years later the patient developed widespread cutaneous involvement with mycosis fungoides, including mycosis fungoides bullosum. The mycosis fungoides progressed to death over the next two years. At autopsy widespread visceral involvement was present. The larynx was extensively infiltrated with mycosis fungoides, and the histology was similar to the original laryngeal biopsy. Although mycosis fungoides is generally thought of as a cutaneous disease, it may rarely present in a squamous epithelium-lined organ other than the skin.

Mental development of preterm infants during the first year.

Developmental rates and standard scores are examined for 56 infants in 4 gestational age groups by repeated measurements on the mental scale of the Bayley Scales of Infant Development. Rates across the first year of life can be predicted largely by a biological model that assumes equality of development for infants of the same conceptual age. However, standard scores based on biological age are elevated during the early months for the most premature groups, indicating a transient advantage of increased extrauterine life. Scores from 3 to 12 months' biological age are slightly higher for the most premature groups but are consistent within groups, with no special acceleration of the premature.
