Auditory Steady State Response

Two studies were aimed at developing the auditory steady-state response (ASSR) for universal newborn hearing screening. First, neonates who had passed auditory brainstem response, transient evoked otoacoustic emission, and distortion-product otoacoustic emission tests were also tested with ASSRs using modulated tones that varied in frequency and level. Pass rates were highest (> 90%) for amplitude-modulated tones presented at levels ≥ 69 dB SPL. The effect of modulation frequency on ASSR for 500- and 2000-Hz tones was evaluated in full-term and premature infants in the second study. Full-term infants had higher pass rates for 2000-Hz tones amplitude modulated at 74 to 106 Hz compared with pass rates for a 500-Hz tone modulated at 58 to 90 Hz. Premature infants had lower pass rates than full-term infants for both carrier frequencies. Systematic investigation of ASSR threshold and the effect of modulation frequency in neonates is needed to adapt the technique for screening.

Chairman Sanford: Dr. Herman N. Bundesen, Commissioner of Health of Chicago, organized 12 years ago the "Chicago Premature Plan." This consists in registering all premature infants with the City Health Department within a few hours after birth. The premature infant who is born at home, or in a hospital that does not have adequate premature care, is transported in an oxygenated incubator ambulance to a hospital which specializes in such care. From 1936 to 1947 premature infant deaths in Chicago have been lowered 6½%. The full term infant death rate during the same period has been lowered about 3%. Inasmuch as the premature death rate has been lowered about double that of the full term infant rate, we believe this procedure has been the cause of reduction. In 1936 there were 47,000 live births in Chicago. In 1947 there were 82,000, or an increase of 80%. In this number the full term infants increased from 45% to 60%, whereas the premature infants increased from 2000 to over 5000, or about 140% increase of premature infants born in Chicago during the last 10 years. This adds a considerable increase to the number of infants for our available premature infants beds. Where formerly we planned 5 premature births to each 100 full term births, we now find that prematures have increased to 8 per 100 full term infants. Causes of prematurity are multiple births, toxemia, heart disease, syphilis, tuberculosis, infections, accidents, premature separation of the placenta and abnormalities of the reproduction tract. It is generally understood that there is a tendency for more premature births among the Negro race than the white race.

Shoulder Girdle Muscle

To document the incidence of and neonatal factors associated with abnormal shoulder girdle muscle tone in premature infants at follow-up, we studied 125 consecutively admitted infants weighing < 1,750 g treated in The Children's Hospital of Philadelphia intensive care nursery and subsequently seen in the Neonatal Follow-up Program up to 18 months of age. Fifty-seven infants (46%) displayed abnormal shoulder girdle muscle tone which presented clinically as scapular retractions. These infants had significantly lower birth weights (P < .001) and gestational age (P < .001) as well as a higher incidence of acute and chronic pulmonary disease (P < 0.01) and CNS insults (P < .05) when compared with infants without scapular retractions. The 57 infants with scapular retractions were further divided into two groups: 42 infants (74%) in whom scapular retractions were associated with generalized mild hypertonicity and 15 infants (26%) in whom scapular retractions compensated for trunk and neck hypotonicity. The infants with scapular retractions and hypotonicity had a significantly higher incidence of neonatal neurologic morbidity including seizures, major resuscitations, and birth asphyxia (P < .01) when compared with the infants with scapular retractions and hypertonicity. Shoulder girdle tone abnormalities in the first year of life inhibit crawling, sitting, and object manipulation and, therefore, may manifest as delays in motor development. Identification of infants with significant neonatal risk factors for tone abnormalities is important to allow for earlier therapeutic intervention.

In the article by J. R. Humbert and R. W. Gotlin,1 the authors state that previous reports in which hypoglycemia was induced artificially with insulin demonstrated a variable growth hormone response. They then refer to the paper by Cornblath, et al.2 as reporting a failure to obtain a rise in growth hormone levels. This is incorrect as we found that insulin-induced hypoglycemia actually resulted in a very marked rise in growth hormone levels in both the full-term and premature infants tested.

Phase platelet counts in a large series of premature infants showed mean levels of 220,000/mm3, 260,000/mm3 and 309,000/mm3 during the first 2 days and in the second and in the fourth week respectively. An additional confirmatory series of infants with weights of 1,500 gm or less showed comparable values. These were followed during the first 2 days, the sixth or seventh day, the tenth or eleventh day, the fourteenth or fifteenth day, and the twenty-eighth to thirtieth day. Mean values were 203,000/mm3, 255,000/mm3, 272,000/mm3, 309,000/mm3, and 354,000/mm3, respectively. A steady rise was generally observed during the first month of life irrespective of birth weight. In the first 2 days of life, platelet values under 150,000/mm3 are more common in premature infants than in full-term babies. However, counts under 100,000/mm3 at any time are unusual and suggest a search for pathological factors. Figures under 50,000/mm3 should be considered frankly abnormal under any circumstances.

Indolic Compounds

The 24-hour urinary excretion of phenolic and indolie compounds, metacatechol-amines, and VMA by full-term and premature infants on their first and fifteenth days of life was studied. The presence of metabolites from all three main catabolic pathways of tryptophan was noted in both groups of infants. 3-indole-acetic and 3-indole-propionic acids were present on the first day of life in the urine of full-term infants, but they were absent on the fifteenth day. Twenty phenolic acids were observed in both groups of infants, but their excretion varied a great deal. Homogentisic acid was not excreted on the first day of life of full-term and premature infants, but it was found in the urine of full-term infants on the fifteenth day of life. The variations of excretion of VMA generally followed that of metacatecholamines. The excretion of VMA by the premature infants on their fifteenth day of life is four- to fivefold that of the first day and reaches adult levels, in contrast to the moderate decrease of VMA excretion of the fuil-term infants on the fifteenth day. The degree of maturation of the enzymic systems involved is discussed as a probable cause of these variations.

Prospective Investigation

A prospective investigation was conducted to determine if infants with necrotizing enterocolitis had evidence of carbohydrate intolerance prior to the onset of clinical symptoms of advanced disease. Stool specimens were examined for fecal reducing substances with Clintest tablets from well, full-term infants and sick premature infants. Only two of 45 (4.4%) formula-fed, full-term infants demonstrated higher than 2 + fecal reducing substances. Ten of 14 (71%) formula-fed premature infants who developed necrotizing enterocolitis had higher than 2 + reducing substances detected in their stools. Daily measurement of fecal reducing substances can be a useful adjunct in the management of sick premature infants.
