Abstract: The present study tested the predictive validity at 3 years of age of a screening device for the early identification of later cognitive delay. The screening device, administered between 3 and 7 months of age, is based on the infant's differential fixation "to novel" over previously shown pictures. The sample was composed of 62 infants suspected to be at risk for later mental retardation. The prevalence of delayed cognitive development (IQ less than or equal to 70) at 3 years of age was 13%. Novelty preference scores correctly identified six of eight (75%) of the delayed children. The test identified 49 of 54 (91%) of the normal children. Validity for predicting cognitive delay was 55%. Validity for the prediction of normality was 96%. The screening device proved to be equally sensitive, specific, and valid when the sample was divided into infants born at term or born preterm. The results of the present study and of a previous study indicate that detection of cognitive delay based on early novelty preferences is as easily accomplished for infants who will later be mildly delayed (IQ scores 60 to 70) as it is for those who will later be severely delayed (IQ scores less than or equal to 50). Moreover, such results are in contrast to those obtained with conventional tests tapping sensorimotor development.
Selective screening device for the early detection of normal or delayed cognitive development in infants at risk for later mental retardation.

Abstract: A clinical trial was undertaken to assess the effects of oral H1 (diphenhydramine hydrochloride) and H2 (cimetidine) histamine blockade on nasal resistance induced by topical histamine. Ten adult volunteers were tested on two separate occasions. Their noses were pretreated by oral administration of either combined H1 and H2 histamine antagonists or H1 antagonist and placebo. The nasal airflow resistive response to topical histamine was then determined. Combined histamine antagonism was significantly more effective in reducing the nasal resistive response to topical histamine than H1 antagonist alone (p less than 0.0001). Furthermore, ingestion of the oral H1 histamine antagonist, diphenhydramine hydrochloride, alone led to an increase in resistance of the unprovoked nose, whereas combined H1 and H2 antagonism did not lead to a significant change.

Abstract: Male Sprague-Dawley rats were maintained on high protein (60%), normal protein (20%), low protein (5%), or no protein (0%) diets for two or four weeks prior to 45 minutes of renal ischemia induced by renal pedicle clamping. Most (93%) of the rats on the high protein diet died within three days following renal ischemia. In addition, 69% of the rats on normal protein diets also died, most before the fourth day following ischemic insult. In contrast, 88% of the rats on the low protein diet lived, although some exhibited elevated serum creatinine levels for up to one to two weeks following ischemia. Finally, all of the rats on no protein diets lived, and most (75%) exhibited normal serum creatinine levels by the fourth day following ischemia. Shifting the diets of high protein and normal protein adapted rats to no protein diets immediately following ischemia did not improve postischemic survival. Also, changing the diets of no protein adapted rats to high protein diets immediately following ischemia did not significantly affect postischemic recovery. When rats were maintained on no protein diets for shorter periods of time prior to ischemia, it was found that approximately a week on this diet is necessary to provide maximum protection from postischemic acute renal failure. These findings demonstrate a dramatic effect of dietary protein prior to ischemic induced acute renal failure, and suggests that preoperative dietary protein intake should be an important consideration in those situations which are predisposed to postoperative acute renal failure.
