OBJECTIVE: The goal was to examine the relationship between age at the introduction of solid foods during the first year of life and allergic sensitization in 5-year-old children. METHODS: We analyzed data from the Finnish Type 1 Diabetes Prediction and Prevention nutrition study, a prospective, birth cohort study. We studied 994 children with HLA-conferred susceptibility to type 1 diabetes mellitus for whom information on breastfeeding, age at the introduction of solid foods, and allergen-specific immunoglobulin E levels at 5 years was available. The association between age at the introduction of solid foods and allergic sensitization was analyzed by using logistic regression. RESULTS: The median duration of exclusive breastfeeding was 1.8 months (range: 0–10 months). After adjustment for potential confounders, late introduction of potatoes (>4 months), oats (>5 months), rye (>7 months), wheat (>6 months), meat (>5.5 months), fish (>8.2 months), and eggs (>10.5 months) was significantly directly associated with sensitization to food allergens. Late introduction of potatoes, rye, meat, and fish was significantly associated with sensitization to any inhalant allergen. In models that included all solid foods that were significantly related to the end points, eggs, oats, and wheat remained the most important foods related to sensitization to food allergens, whereas potatoes and fish were the most important foods associated with inhalant allergic sensitization. We found no evidence of reverse causality, taking into account parental allergic rhinitis and asthma. CONCLUSION: Late introduction of solid foods was associated with increased risk of allergic sensitization to food and inhalant allergens.

Gabapentin alleviates and/or prevents acute nociceptive and inflammatory pain both in animals and volunteers, especially when given before trauma. Gabapentin might also reduce postoperative pain. To test the hypothesis that gabapentin reduces the postoperative need for additional pain treatment (postoperative opioid sparing effect of gabapentin in humans), we gave 1200 mg of gabapentin or 15 mg of oxazepam (active placebo) 2.5 h prior to induction of anaesthesia to patients undergoing elective vaginal hysterectomy in an active placebo-controlled, double blind, randomised study. Gabapentin reduced the need for additional postoperative pain treatment (PCA boluses of 50 microg of fentanyl) by 40% during the first 20 postoperative hours. During the first 2 postoperative hours pain scores at rest and worst pain score (VAS 0-100 mm) were significantly higher in the active placebo group compared to the gabapentin-treated patients. Additionally, pretreatment with gabapentin reduced the degree of postoperative nausea and incidence of vomiting/retching possibly either due to the diminished need for postoperative pain treatment with opioids or because of an anti-emetic effect of gabapentin itself. No preoperative differences between the two groups were encountered with respect to the side effects of the premedication. However, 15 mg oxazepam was more effective in relieving preoperative anxiety than 1200 mg gabapentin.

The current study investigated factors contributing to mother's early perception of her infant's difficult temperament. One hundred and twenty-four mother-infant dyads participated in the study. Mother's perception of the infant's temperament was assessed with the Infant Characteristics Questionnaire (ICQ). The influence of mother-infant interaction, mother's mental health and parenting stress were investigated. Mother-infant interaction was videotaped during a face-to-face interaction and analysed using the Global Rating Scale. Mother's mental health was assessed through a structured interview (Structured Clinical Interview for DSM-IV, SCID) and parenting stress was examined by a questionnaire (Parenting Stress Index). First, the difficulty scale of the ICQ was used as a continuous variable and factors contributing to mother's perception of her infant's temperament as more or less difficult were examined. Secondly, infants were categorized into difficult and non-difficult, and factors increasing the infant's risk of being perceived as difficult were examined. The model including mother's mental health and parental distress accounted for 24% of the variance in perceived infant difficulty, with parental distress in particular being an influential contributor. When infants categorized as difficult were examined, mother's intrusiveness and infant's poor interactive behaviour in early mother-infant interaction as well as parental distress significantly increased the infant's risk of being perceived as difficult.

The results showed active visiting by the parents in the NICU. A lower gestational age was associated with lower visiting frequency for mothers. In contrast, more practical limitations such as geographical distance and other children to be taken care of had greater effect on the visiting frequency for fathers.

The present study investigated whether autonomic arousal to direct gaze is related to social impairments among children with autism spectrum disorder (ASD). Arousal was measured through skin conductance responses (SCR) while the participants (15 children with ASD and 16 control children) viewed a live face of another person. Impairments in social skills was assessed with the Developmental, Dimensional and Diagnostic Interview. The level of arousal enhancement to direct gaze in comparison to arousal to faces with averted gaze or closed eyes was positively associated with impairments in social skills (use of language and other social communication skills and use of gesture and non-verbal play) among children with ASD. There was no similar association among children without ASD. The role of arousal-related factors in influencing eye contact behaviour in ASD is discussed.
