Indecomposable factorizations of multigraphs

AbstractA one-factorization of a complete multigraph is called decomposable if some proper subset of the factors also forms a one-factorization of a complete multigraph; otherwise it is indecomposable. Some results on the existence of indecomposable one-factorizations will be proven

Quasi-residual quasi-symmetric designs

AbstractIt is shown that for each λ ⩾ 3, there are only finitely many quasi-residual quasi-symmetric (QRQS) designs and that for each pair of intersection numbers (x, y) not equal to (0, 1) or (1, 2), there are only finitely many QRQS designs.A design is shown to be affine if and only if it is QRQS with x = 0. A projective design is defined as a symmetric design which has an affine residual. For a projective design, the block-derived design and the dual of the point-derivate of the residual are multiples of symmetric designs

The Role of Comorbid Mood Disorders in Cognitive Behavioral Therapy for Childhood Social Anxiety

Background: Children with a social anxiety disorder have worse treatment outcomes after Cognitive Behavior Therapy (CBT) than children with other anxiety disorders. Anxiety disorders and mood disorders are strongly related and especially social anxiety is related to high comorbidity rates with mood disorders. The aim of the study was to investigate how comorbid mood disorders are related to treatment outcomes after CBT and whether this can explain the worse outcomes for childhood social anxiety. Methods: Participants were 152 referred clinically children (7–18 years) with either a social anxiety disorder (n = 52) or another anxiety disorder (n = 100) of whom 24.3% (n = 37) had a comorbid mood disorder. Child anxiety, internalizing symptoms, and quality of life were measured pre-treatment, post-treatment, 3 months and 1 year after treatment, using child and both parents’ report. Results: Children with a primary social anxiety disorder more often had a comorbid mood disorder than children with another primary anxiety disorder. Children with a mood disorder had more severe anxiety problems before treatment. Comorbid mood disorders were related to greater anxiety reductions after treatment. The worse outcomes for children with a primary social anxiety disorder remained after controlling for comorbid mood disorders. Conclusions: Findings stress the importance of future studies examining why the presence of a comorbid mood disorder is associated with greater anxiety reductions, and other factors that explain the worse treatment outcomes found for childhood social anxiety disorder.</p

Use of skin substitute dressings in the treatment of staphylococcal scalded skin syndrome in neonates and young infants

Background: Staphylococcal scalded skin syndrome (SSSS) is a rare toxin-mediated skin disease caused by Staphylococcus aureus and seen in infants and children younger than 5 years. Objectives: The supportive role of skin substitutes in SSSS is stressed as a new and relatively unknown method. Methods: Retrospective observational case-series study, in neonates and young infants diagnosed with SSSS. Results: Seven infants with SSSS, treatment with antibiotics, skin substitutes, strict pain relief strategy and prognosis were described. One of them was severely affected and deceased. Conclusion: This study describes 7 infants with SSSS and stresses the important role of skin substitutes as Omiderm® and Suprathel® as valuable adjuvant treatment modality. Copyrigh
