The consequences of pain in early life: injury-induced plasticity in developing pain pathways.
Pain in infancy influences pain reactivity in later life, but how and why this occurs is poorly understood. Here we review the evidence for developmental plasticity of nociceptive pathways in animal models and discuss the peripheral and central mechanisms that underlie this plasticity. ⋯ Peripheral nerve sprouting and dorsal horn central sensitization, disinhibition and neuroimmune priming are discussed in relation to the increased pain and hyperalgesia, while altered descending pain control systems driven, in part, by changes in the stress/HPA axis are discussed in relation to the widespread hypoalgesia. Finally, it is proposed that the endocannabinoid system deserves further attention in the search for mechanisms underlying injury-induced changes in pain processing in infants and children.

A short cut review was carried out to establish whether ultrasound was better than x-ray at detecting fractured ribs after minor chest trauma. Two papers presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that while current studies suggest ultrasonography is better than x-ray at detecting rib fractures, further studies with a well-established gold standard should be completed before ultrasonography is used routinely.

The probability of survival (PS) in blunt trauma as calculated by Trauma and Injury Severity Score (TRISS) has been an indispensable tool in trauma audit. The aim of this study is to explore the predictive performance of the latest updated TRISS model by investigating the Age variable recategorisations and application of local Injury Severity Score (ISS) and Revised Trauma Score (RTS) coefficients in a logistic model using a level I trauma centre database involving Asian population. ⋯ The present study has demonstrated that (1) having the Age variable being dichotomised (cut-off at 55 years) as in the eTRISS, but with the application of a local dataset-derived coefficients give better TRISS survival prediction in Asian blunt trauma patients; (2) improved performance are found with certain recategorisation of the Age variable and (3) the accuracy can further be enhanced if the Age effect is taken to be linear, with the application of local dataset-derived coefficients.

We review the English literature between 1980 and 2013 and summarize the clinical classification, aetiology, physiology, and pathophysiology of paediatric priapism. We propose a clinical guideline for the management of priapism in children. ⋯ Priapism in children must be assessed urgently. Rapid resolution of ischaemic priapism prevents permanent cavernosal structural damage and is associated with improved prognosis for potency later in life. Stuttering priapism requires careful counselling for episodic management. Chronic prophylaxis may be obtained using α-adrenergic sympathomimetics, phosphodiesterase type 5 inhibitors and, in sickle cell disease, hydroxyurea. Non-ischaemic and neonatal priapism may generally be treated less urgently.
