A large-scale population trial using the Triple P-Positive Parenting Program (TPS) was evaluated. The target population was all parents of 4- to 7-year-old children residing in ten geographical catchment areas in Brisbane (intervention communities) and ten sociodemographically matched catchment areas from Sydney (5) and Melbourne (5), care as usual (CAU) comparison communities. All five levels of the Triple P multilevel system of intervention were employed; including a local mass media strategy, a primary care strategy, and three more intensive levels of parenting intervention delivered by a range of service providers (e.g., health, education, and welfare sectors). Program outcomes were assessed through a computer-assisted telephone interview of a random sample of households (N = 3000) in each community at pre-intervention and again at two years post-intervention. At post-intervention there were significantly greater reductions in the TPS communities in the number of children with clinically elevated and borderline behavioral and emotional problems compared to the CAU communities. Similarly parents reported a greater reduction in the prevalence of depression, stress and coercive parenting. Findings show the feasibility of targeting dysfunctional parenting practices in a cost-effective manner and the public acceptance of an approach that blends universal and targeted program elements. Editors' Strategic Implications: This is the first positive parenting program to demonstrate longitudinal, population-level effects for parents and children. The authors provide an excellent example of multilevel prevention planning, coordination, execution, and evaluation.

Thoracoscopy for ligation of the thoracic duct and pericardectomy is an acceptable surgical technique for treatment of chylothorax.

Compared with baseline values and values obtained from dogs in the SAL group, ketamine administered at a dose of 5 mg/kg, IV, caused a significant and clinically important increase in IOP in dogs in which premedication was not administered. Ketamine should not be used in dogs with corneal trauma or glaucoma or in those undergoing intraocular surgery.
