摘要:

The increased viability of extremely low birth weight (ELBW) infants (those weighing less than 1000 g) and the associated increased risk of visual impairment has highlighted the need for reliable indices of visual functioning for this population. By use of the Teller Acuity Cards, we assessed grating visual acuity in 26 survivors of extreme prematurity (corrected age, 2–42 mo) and found that although most scores were within the normal range, they were significantly lower than those of full-term infants of equivalent postconceptional age, especially after 9 months of age. Moreover, the number of complications in the neonatal period (especially bronchopulmonary dysplasia) and the Neonatal Medical Index classification were associated with below-average visual acuity in infancy and early childhood.

摘要:

The prediction of early childhood attention problems was investigated prospectively within a sample of low birth weight children. Medical risk, temperament, quality of home environment, and developmental status were correlated with task measures of inattention and impulsivity; developmental status and quality of home environment were correlated with examiner ratings of inattention, impulsivity, and hyperactivity during testing; and quality of home environment was correlated with parental reports of hyperactivity. Multiple regression analyses indicated that attention problems were predicted by temperament, environment, and the interaction between developmental status and quality of home environment. These findings support the usefulness of a multidimensional approach to the measurement of attention problems and a multivariate approach to prediction and suggest that quality of home environment, in interaction with characteristics of the infant, influences the development of self-regulation and attention among low birth weight children.

摘要:

Non-nutritive sucking (NNS) activities were recorded in preterm infants born at gestational age 32 weeks or less during nasogastric feedings. Six infants on intermittent nasogastric feeding schedules were tested with a pacifier in their mouth for three 5-minute periods (before, during, and after gavage feeding). Analysis of the recordings revealed that NNS activities increased markedly during the intermittent nasogastric feeding schedule. The overall proportions of sucking engagement, the mean duration of sucking burst, the mean number of sucks per burst, and the mean duration of individual sucks within a burst increased markedly during gavage feeding compared with both pre-test and post-test periods. NNS by a group of five infants on continuous nasogastric feedings was similar to the pre-test and post-test of the infants on the intermittent nasogastric feeding schedule. These results indicate that in the context of intermittent nasogastric feedings, NNS engagement in tube-fed infants depends on stomach cues and/or temperature changes associated with tube feedings.

摘要:

We examined the influence of cognitive factors and conditioning variables on anticipatory nausea and vomiting symptoms (ANV) in 32 pediatric cancer patients with postchemotherapy nausea and vomiting (PNV) who received ondansetron. The patients were compared with 18 patients without ANV (NANV). Age, gender, history of motion sickness, aggressiveness of the chemotherapy, PNV severity, number of chemotherapy treatments, number, type, and efficacy of self-reported coping strategies, and expectations of severity of postchemotherapy symptoms failed to differentiate the ANV and NANV groups. The amount of subjective distress associated with nausea and vomiting was significantly greater in the ANV group. Among patients in whom ANV developed, level of distress and expectations of severity of postchemotherapy symptoms were positively correlated with the severity of ANV and PNV symptoms. Therefore, greater distress might increase the likelihood of ANV conditioning. Once ANV is conditioned, cognitive factors might influence the severity of symptoms.

摘要:

Behavioral and medical treatments for toileting refusal (TR) were investigated using two additive treatments in a multiple-baseline design with 11 preschool-aged children. After Pretreatment A, Treatment B increased high-fiber foods and liquids, initiated mineral-oil therapy, and added positive reinforcement for appropriate toileting. After bowel clean-out, Treatment C induced daily bowel movements with suppositories and applied negative behavioral consequences for inappropriate toileting. Behaviors measured were appropriate and inappropriate bowel movements. Treatment B alone eliminated TR in three boys in 27 to 36 days and reduced the TR of one girl in 40 days. When indicated, Treatment B+C eliminated TR in two boys and four girls in 37 to 79 days and reduced the TR of one boy in 92 days. All 11 of the children were accident free and having at least one bowel movement every 2 days during 5 consecutive days of follow-up conducted 3 to 4 months after treatment. Parents reported general satisfaction with the treatment
