We describe and report the results of a multicomponent behavioral intervention for re-establishing solid food consumption in a 26-year-old woman with prolonged food avoidance and restriction which developed following a traumatic brain injury. The intervention was evaluated by direct measurement of daily meal consumption over a period of several months, including an extended follow-up, and resulted in successful resumption of oral feeding. A complicating paroxysmal movement disorder resolved during treatment as well and resolution of the presenting problem led to significant quality of life improvements. We discuss the relationship of the presenting symptoms to avoidant/restrictive food intake disorder and to food rejection behavior seen when substantial damage has occurred to the parietal lobe. The case illustrates the value of assessment-based, individualized intervention design and an integrated neurobehavioral case conceptualization.

Suitable nutrition in children is critical to development. It has long been recognised that under-nutrition can lead to faltering growth, however, there is also increasing concern over the rising number of children who are overweight and classified as obese. Babies initially receive all their nourishment through exclusive milk feeding, either breast or bottle, but this soon becomes nutritionally inadequate and needs replacing with solid foods. This process of weaning onto a solid diet can be a stressful time for parents. Conflicting messages from family, friends and healthcare professionals make it difficult for parents to decide how best to introduce solid foods into their child’s diet. This article looks to provide an overview of infant nutrition with a particular focus on weaning and the current evidence surrounding the process.

Background: Introducing solids foods to infants before 6 months has been associated with adverse long-term health outcomes. Studies and surveys frequently use maternal report to identify the age when infants start solid foods. Objective: To address the accuracy of maternal report at 1 year postpartum regarding introduction of solid foods. Methods: Between 2008 and 2009, the authors enrolled mothers of healthy term singletons at an urban Boston hospital within 72 hours of giving birth. We called mothers monthly for 6 months and asked if they had given their baby solid foods in the previous month. At 1 year, we contacted mothers again and asked when they first gave solid foods; answers at 1 year were compared with the data collected monthly. Results: The authors analyzed data on 157 women, all of whom had, according to monthly responses, started solid foods before 6 months. At 1 year, only 14% (22/157) of reports matched data recorded monthly. Although 100% of women introduced solids before 6 months, at 1 year, 41.4% reported starting solids at 6 months. Conclusions: Among women who started feeding solids before 6 months, most did not give an accurate response at 1 year. Most said they started giving solids later than they did. Maternal report may not be the best way to collect such data, and health outcomes based on such data may be biased toward the null.

We aimed to compare the effects of lidocaine and adrenaline with ibuprofen syrup (administered before adenotonsillectomy) on post-operative analgesia and initiation of oral feeding. One group of 20 children received 100 g/5 ml ibuprofen suspension (10 mg/kg) 1 h before anaesthesia; bleeding control was provided by pre-incisional administration of 1:200000 adrenaline solution (10 ml). The same amount of 0.5% lidocaine solution plus 1:200000 adrenaline was applied pre-incisionally in a similar manner in a second group of 20 children. No significant differences were observed between the two groups in terms of the duration of operation and anaesthesia, post-operative pain scores, paracetamol requirements, times to initiation of liquid and solid food intake, or adverse side-effects. We conclude that ibuprofen syrup applied pre-incisionally and local infiltration with lidocaine are equally effective for post-operative analgesia.

This study was a cross-sectional survey of primary female caregivers during their childs 4-month well-child visit. Our objectives were to document current caregiver awareness of infant feeding guidelines, and calculate the frequency of and reasons for early introduction of solid foods. Questionnaires were completed for 102 children. Forty-five respondents (44%) introduced solids at less than 4 months of age. Hispanic caregivers, OR 0.2 (0.07-0.9), and those who breastfed (partial or exclusive), OR 0.4 (0.2-0.9), were less likely to introduce cereal at less than 4 months of age. Among caregivers who introduced solids at less than 4 months, 36 (80%) stated that the child was not satisfied with formula or breast milk alone and 24 (53%) stated that solids helped the child sleep better at night. Thirty-four caregivers (76%) who started solids at less than 4 months were aware of guidelines regarding proper infant feeding practices. Despite knowledge of infant feeding guidelines, female caregivers frequently introduce solids at less than 4 months of age. Early targeted anticipatory guidance is needed to address the most common reasons caregivers begin solid foods before the recommended age.

Fresh food products can be processed using UV light as a germicidal medium to reduce the food-borne microbial load. Water has been treated with UV light to obtain drinking water for quite some time. Pumpable fruit and vegetable products are generally very suitable for processing by UV light to reduce the microbial load. Today, most of these products are pasteurised to obtain microbiologically safe and nutritious products. However, pasteurisation can change the taste and flavour of such products because of the temperature and processing time. Juices from different sources can be treated by exposure to UV light at different doses. On the other hand, variables such as flow rate, exposure time, type of fruit product, juice colour and juice composition, among other variables, need to be studied to obtain fruit products with reduced microbial load, increased shelf life and adequate sensory and nutritional characteristics. Reduction of microbial load through UV light application as a disinfection medium for food products other than liquids is also being studied. Moreover, UV technology could be a source for pasteurisation of liquids, or disinfection of solid foods as an alternative technology, instead of thermal treatment or application of antimicrobial compounds.

Reducing water availability is one way to preserve food. Water in solid foods is transferred to a fluid, either gas or liquid; during this process both internal and external resistance affect water transfer from the food. As a consequence, any means to reduce those resistances constitute an improvement of the process, and ultrasound appears to be a way to reduce those resistances. Ultrasound are mechanical waves that produce different effects when travelling through a medium. Among others, those related to mass transfer include micro-stirring at the interface, the so called “sponge effect” and cavitations. Ultrasound has so far been applied to dehydration in solid-gas systems like onion drying. Nevertheless, the difficulties for the propagation in the air have led to the development of specially adapted transducers that have been applied in the drying of carrots. In solid-liquid systems, ultrasound has been used in the treatment of products immersed in hypertonic solutions, either in sugar solutions for fruits like apples or in salt brine in the case of cheese or meat. An increase in mass transfer is achieved if the threshold power value for the product is attained.

A 4-year-old with primary solid food refusal was treated with systematic fading of utensil type and food texture, using a multiple probe design across food groups. The subject was a multi-handicapped boy hospitalized for feeding problems, self-injurious behaviors, and sleep cycle reversal. At admission, the subject received all nutrition in the form of a liquid nutritional supplement through regular bottle feedings every half hour. Craniofacial anomalies and past multiple facial surgeries precluded the use of a physical prompting procedure. During the first treatment phase, pureed foods were presented with a preexisting stimulus (a regularbaby bottle). Accepted presentations were reinforced with music delivered through headphones. All other behaviors received neutral consequences. In the second treatment phase, undiluted pureed foods were presented in bottles, which allowed experimenter control of the size of the bolus entering the mouth. Consequences were identical to those in Treatment 1. Next, spoon-feedings were introduced with the same consequences in place. Reinforcement with a newly acquired preferred food was initiated and faded to a variable ratio three (VR3) schedule. This fading procedure was effective in teaching this young multihandicapped child to consume a nutritionally balanced diet of pureed foods with an average acceptance of 94% and a concomitant decrease in inappropriate mealtime behaviors.

A longitudinal prospective study was performed to investigate the total duration of breast-feeding. Three hundred and sixty-six mothers were followed-up until 3 years after delivery. At 1 month 93% were breast-feeding, at 3 months 73%, at 6 months 52%, at 1 year 20% and 1% breast-fed more than 3 years. Correlations were found between duration of breast-feeding and maternal age, education and social class. Mothers who had breast-fed an older child usually breast-fed the next child for a period of similar length. Solid food was most frequently introduced when the infants were 4 months old. At 6 months 4% were still exclusively breast-fed. Breast-feeding has become popular: only 1% did not want to breast-feed at all and 89% of mothers intended to breast-feed their children for 6 months or more. Even though the mothers now breast-feed longer than earlier, only 39% succeeded in breast-feeding for as long as or longer than they had intended.

Summary 6 litters of Octodon degus were studied from birth to 10 days of age. Newly-born degus (mean weight 14·6 g) had open eyes, upper and lower pigment, für, and teeth. Within 3–4 hours of birth they were able to walk supporting their full weight, right themselves rapidly, sit upright on their haunches, or rear upright with support, and vocalize. By the 1st or 2nd day, the young animals displayed functional grooming (face washing, hind-paw scratching, rapid head-shake). Solid food was ingested from day 6, although newborns chewed wood chips and 3–day olds gnawed dried faeces. Young degus were tested daily in an open field apparatus and showed increased activity and exploration, with repeated testing while decreasing distress vocalization after the 4th or 5th day. Degus are proposed for the study of developmental topics since their degree of development at birth allows for immediate testing. The degus studied here seem to be more fully developed at birth than those studied in Britain.

The feeding behavior of obese ( ob/ob), diabetic ( db2s/ db2s), and viable yellow ( Avv/a) mice was assessed in 2 separate experiments. When given access to solid food and sweet liquid food simultaneously, fat mutant mice ingest large quantities of sweet liquid food and gain weight more rapidly than controls. The behavior of diabetic and obese mice in this situation is quite similar. When given access to sweet liquid food reinforcement in an operant conditioning situation the behavior of the three mutant genotypes differs. The response rate of obese mice does not appear to be schedule dependent, while that of viable yellow mice clearly is schedule dependent. The response rates of viable yellow mice are consistently higher than the rates of their controls. The behavior of a diabetic mouse does not appear different from that of a control mouse in this situation. The use of mutant genotypes as “natural preparations” comparable to experimentally induced lesions is discussed.

SummaryPhysiological activity of the parotid gland was reduced by maintenance of immature and adult rats on a liquid diet. The general status of the gland was determined by measurements of weight while the status of the individual cellular components was determined by measurements of cell size and nucleic acids. In the developing parotid, reduced physiological activity inhibited the growth of the gland by inhibiting growth in both cell number and cell size. In the mature parotid, reduced physiological activity resulted in a decrease in cell size only. When glandular activity was returned to normal by feeding solid food in both the immature and adult rat, the gland and its cellular components were restored to expected levels.

The clinical picture of adrenal insufficiency in animals has been described by many authors. Certain of the blood changes have also been described, but for the most part these have been isolated or terminal findings. Our experiments have extended the chemical studies to day by day observations. We find that a fall in CO2 capacity, a non-protein nitrogen rise, a chloride fall and a fall in blood sugar occur in experimental adrenal insufficiency. The blood-chemical picture has been correlated with observed symptoms of loss of appetite, asthenia, dehydration, and decreased peripheral circulation.Injection of our adrenin-free extract of the adrenal cortex,1 brings about a reversal of the shift in adrenal insufficiency. The CO2 capacity and blood chlorides rise to normal, the non-protein nitrogen fails to rise, and the blood sugar increases. There is in adrenalectomized cats an immediate clinical improvement and their appetite for solid food returns. A few animals injected while in a comatose state, have soon ...
