Toileting concerns, parenting stress, and behavior problems in children with special health care needs.

This study examined the relationship between toileting concerns, behavior problems, and parenting stress in parents of children with special health care needs (CSHCN). Participants included parents of 99 males and 71 females aged 4 to 12 years with neural tube defects (NTD), developmental-behavioral disabilities (DBD), or history of perinatal intraventricular hemorrhage (IVH). Parents completed the Achenbach Child Behavior Checklist (CBCL) and the Parenting Stress Index-Short Form (PSI-SF). Parents expressing toileting concerns on the CBCL reported significantly more personal distress and more externalizing problems versus those with continent children. Variation within subsamples suggested that expectations based on nature of disability may be a factor in parent adjustment. Direct assessment and intervention of toileting issues should be a high priority in secondary stress prevention with CSHCN and their families.

Methods for inducing apoptosis.

Apoptotic cells are sources of tolerogenic material during tissue homeostasis; abnormalities in apoptosis or in the clearance of apoptotic material generate a novel source of antigens against which an autoimmune response may be initiated. In our laboratory, we study the biochemistry and cell biology of systemic autoimmune disease autoantigens during different forms of cell death. Several different methods for inducing apoptosis, and for assaying the induction of this cellular process, are routinely performed. This chapter describes methods for inducing apoptosis via ultraviolet B irradiation, small molecule drug treatments, death receptor ligation, and exposure to granule components of cytotoxic lymphocytes. Assays to confirm the induction of apoptosis by quantifying changes in mitochondrial membrane potential, phosphatidylserine membrane localization, DNA content, and autoantigen cleavage are also detailed.
