Spectrum and origin of phenylketonuria mutations in Spain

In order to characterize the molecular heterogeneity of phenylalanine hydroxylase deficiencies in the Spanish population, 37 PKU patients were initially screened for 16 known European mutations. For the remaining unidentified alleles, we used a combined strategy based on single strand conformation polymorphism analysis and DNA sequencing. Overall, a total of 15 different mutations were found in our sample, which account for 62% of the total mutant alleles. We also investigated the association between the mutations, haplotypes and variable number of tandem repeats described on the phenylalanine hydroxylase gene. In addition, we analyzed the geographical distribution in Spain of the two most prevalent mutations in our population: IVS10 and I65T.     

Eating disorders and irritable bowel syndrome: is there a link?

OBJECTIVE: The relationship between eating disorders (ED) and irritable bowel syndrome (IBS) is poorly understood. We wanted to determine the prevalence of IBS in a large sample of eating disordered individuals, examine the timing of onset of these disorders and assess whether there are any predictors of IBS symptoms in ED sufferers. METHODS: Participants with a current or past ED were recruited from a volunteer register. Two hundred thirty-four respondents completed a questionnaire on IBS devised for the study. ED symptoms were assessed using the Eating Disorders Examination-Questionnaire (EDE-Q). RESULTS: Sixty-four percent currently met the widely used Manning criteria for IBS. The majority of participants (87%) had developed their ED before the onset of IBS, with a mean of 10 years between the onset of ED and IBS. All EDE subscales were associated with current IBS symptoms, whereas ED duration was not. CONCLUSION: Preliminary findings suggest that EDs may increase the risk of developing IBS.     

Psychosocial adjustment in preschool children with atopic eczema

Atopic eczema is a chronic skin disorder that is most common in early childhood, an important stage in the child's social and emotional development. The psychiatric adjustment and mother-child attachment in 30 preschool children with severe atopic eczema was compared with 20 matched controls. Patients with eczema had a significant increase in behaviour symptoms, 7/30 (23%) v 1/20 (5%); with significant excess of dependency/clinginess, 15/30 (50%) v 2/20 (10%); fearfulness, 12/30 (40%) v 2/20 (10%); and sleep difficulty, 19/30 (63%) v 9/20 (45%), but there was no significant difference between the two groups in the security of attachments, 25/29 (86%) v 14/20 (70%). Significantly fewer mothers of children with atopic eczema were in outside employment, 8/29 (27%) v 13/20 (65%), or felt supported socially, 10/29 (34%) v 13/20 (65%). Significantly more of them, 9/30 (30%) v 1/20 (5%), felt particularly stressed in relation to their parenting and less efficient in their disciplining of the affected child. In spite of this and at variance with earlier reports in the literature, they did not display negative attitudes towards their child. On the contrary mothers had a positive empathic attitude towards the child, 7/14 (50%) v 2/16 (12%). Child behaviour problems, 7/14 (50%) v 2/16 (12%), and maternal distress, 12/14 (85%) v 5/16 (31%), were significantly more common in the more severely affected children. Minor behaviour problems and parenting distress are important features of severe atopic eczema in early childhood but atopic eczema does not lead to insecurity of the mother-child attachment.
