Reconstruction of the nasal osseocartilaginous framework is the foundation of successful primary and secondary rhinoplasty. When adequate septal cartilage is unavailable, the rib provides the most abundant source of cartilage for graft fabrication and is the most reliable when structural support is needed. We present the senior author's (J.P.G.) experience and evolution of techniques of dorsal augmentation with autogenous rib cartilage grafts with internal K-wire stabilization in rhinoplasty.

Background: Healthy individuals demonstrate considerable heterogeneity upon dynamic quantitative sensory testing assessment of endogenous pain modulatory mechanisms. For those who stratify into a 'pro-nociceptive profile' cohort, consisting of inefficient conditioned pain modulation (CPM) and elevated temporal summation of pain (TSP), the optimal approach for balancing the net output of pain modulatory processes towards anti-nociception remains unresolved. In this translational healthy human and rat study, we examined whether descending modulation countered spinal amplification during concurrent application of a CPM and TSP paradigm alongside pupillometry since pontine activity was previously linked to functionality of endogenous pain modulatory mechanisms and pupil dilation.

Osteoporosis-related vertebral fractures are among the most frequent fracture entities in geriatric patients. They are associated with far-reaching individual and socioeconomic consequences. Adequate diagnostics and treatment are therefore essential.

Reward prediction errors (RPEs) quantify the difference between expected and actual rewards, serving to refine future actions. Although reinforcement learning (RL) provides ample theoretical evidence suggesting that the long-term accumulation of these error signals improves learning efficiency, it remains unclear whether the brain uses similar mechanisms. To explore this, we constructed RL-based theoretical models and used multiregional two-photon calcium imaging in the mouse dorsal cortex.

Controversy still surrounds the recommendations for treatment and the available procedures for surgical stabilization.

Background: There is growing interest in use of transcutaneous spinal stimulation (TSS) for people with neurologic conditions both to augment volitional control (by facilitating motoneuron excitability), and to decrease spasticity (by activating inhibitory networks). Various electrode montages are used during TSS, with little understanding of how electrode position influences spinal circuit activation. We sought to identify the thoracolumbar electrode montage associated with the most robust activation of spinal circuits by comparing posterior root-muscle reflexes (PRM reflexes) elicited by 6 montages.
