The emotional health and wellbeing of children and adolescents and their families is of utmost importance. Pediatricians are at the front line in identifying mental illness in children and adolescents and either linking them to resources in the community or providing treatment options themselves. Collaboration and integrative health care models is the cornerstone of effective strategies to provide access and quality mental health care to children and families in communities across the country.

The goal of this Clinical Perspectives is to present pediatric medicine updates on populations seen in child psychiatry settings. Physicians trained in palliative care and child psychiatry, pediatrics and psychiatry, and child psychiatry will present a pediatric medicine perspective on the status of palliative care and chronic pain treatment and the multidisciplinary approach to patients in these unique populations.

Abstract: The objective of this study was to develop a novel method to more accurately reproduce previously recorded 6-DOF kinematics of the tibia with respect to the femur using robotic technology. Furthermore, the effect of performing only a single or multiple registrations and the effect of robot joint configuration were investigated. A single registration consisted of registering the tibia and femur with respect to the robot at full extension and reproducing all kinematics while multiple registrations consisted of registering the bones at each flexion angle and reproducing only the kinematics of the corresponding flexion angle. Kinematics of the knee in response to an anterior (134N) and combined internal/external (±10Nm) and varus/valgus (±5Nm) loads were collected at 0°, 15°, 30°, 60°, and 90° of flexion. A six axes, serial-articulated robotic manipulator (PUMA Model 762) was calibrated and the working volume was reduced to improve the robot''s accuracy. The effect of the robot joint configuration was determined by performing single and multiple registrations for three selected configurations. For each robot joint configuration, the accuracy in position of the reproduced kinematics improved after multiple registrations (0.7±0.3, 1.2±0.5, and 0.9±0.2mm, respectively) when compared to only a single registration (1.3±0.9, 2.0±1.0, and 1.5±0.7mm, respectively) (). The accuracy in position of each robot joint configuration was unique as significant differences were detected between each of the configurations. These data demonstrate that the number of registrations and the robot joint configuration both affect the accuracy of the reproduced kinematics. Therefore, when using robotic technology to reproduce previously recorded kinematics, it may be necessary to perform these analyses for each individual robotic system and for each diarthrodial joint, as different joints will require the robot to be placed in different robot joint configurations.

Abstract: Biomechanical testing protocols for ligaments can be extensive and span two or more days. During this time, a specimen may have to undergo more than one cycle of freezing and thawing. Thus, the objective of this study was to evaluate the effects of refreezing on the viscoelastic and tensile properties of ligaments. The femur-medial collateral ligament-tibia complexes (FMTC) from six pairs of rabbit knees were used for this study. Following sacrifice, one leg in each pair was assigned to the fresh group and the FMTC was immediately dissected and prepared for testing. The contralateral knees were fresh-frozen at −20°C for 3 weeks, thawed, dissected and then refrozen for one additional week before being tested as the refrozen group. The cross-sectional area and shape of the medial collateral ligament (MCL) was measured using a laser micrometer system. Stress relaxation and cyclic stress-relaxation tests in uniaxial tension were performed followed by a load to failure test. When the viscoelastic behavior of the MCL was described by the quasi-linear viscoelastic (QLV) theory, no statistically significant differences could be detected for the five constants (A, B, C, , and ) between the fresh and refrozen groups () based on our sample size. In addition, the structural properties of the FMTCs and the mechanical properties of the MCLs were also found to be similar between the two groups (). These results suggest that careful refreezing of the specimens had little or no effect on the biomechanical properties measured. [Copyright &y& Elsevier]

Study measures at these visits assessed mothers' life experiences, mental health, parenting stress, and perceptions of their relationships with their children and child social-emotional and behavioral functioning. Mothers' PTSD symptoms were related to stress of having a difficult child (r = 0.46, p < 0.01), total parenting stress (r = 0.59, p < 0.01), and child social-emotional problems (r = 0.58, p < 0.01). Preliminary results indicate that Mom Power SP © sp may reduce maternal mental health symptoms and improve the parent-child relationship among highly burdened families. [Extracted from the article]
