Acute and chronic pain management in sport medicine: an expert opinion looking at an alternative mechanism-based approach to the pharmacological treatment.

In the last decades there has been a huge increase in people who practice sports requesting an increase of the performance. Consequently, also incidence of acute and chronic pain is highly increased in this population of "healthy" people. Pain represents not only a signal of a lesion occurred during the sportive activity, but also (and almost) an unbalance of posture or an overuse of specific articulations or muscles, that has to be resolved not only with a correct physiotherapeutic approach, but also with a careful diagnosis of the complex mechanisms that sustain the pain.

Regional anesthesia techniques and postoperative delirium: systematic review and meta-analysis.

Introduction: Postoperative delirium is a frequent occurrence in the elderly surgical population. As a comprehensive list of predictive factors remains unknown, an opioid-sparing approach incorporating regional anesthesia techniques has been suggested to decrease its incidence. Due to the lack of conclusive evidence on the topic, we conducted a systematic review and meta-analysis to investigate the potential impact of regional anesthesia and analgesia on postoperative delirium.

A Frequency-domain Approach to Noninvasive Intracranial Pressure Estimation.

Intracranial pressure (ICP) is a cranial vital sign, crucial in the monitoring and treatment of several neurological injuries. The clinically accepted measurement modalities of ICP are highly invasive, carrying risks of infection and limiting the benefits of ICP measurement to a small subset of critically ill patients. This work aims to take a step towards developing an accurate noninvasive means of estimating ICP, by utilizing a model-based frequency-domain approach.

A Spectral Approach to Model-Based Noninvasive Intracranial Pressure Estimation.

Background: Intracranial pressure (ICP) normally ranges from 5 to 15 mmHg. Elevation in ICP is an important clinical indicator of neurological injury, and ICP is therefore monitored routinely in several neurological conditions to guide diagnosis and treatment decisions. Current measurement modalities for ICP monitoring are highly invasive, largely limiting the measurement to critically ill patients.

An Explorative Study of CYP2D6's Polymorphism in a Sample of Chronic Pain Patients.

Background: A proper antalgic treatment is based on the use of titrated drugs to provide adequate relief and a good tolerability profile. Therapies have a variable effectiveness among subjects depending on medical and genetic conditions. CYP2D6 variations determine a different clinical response to most analgesic drugs commonly used in daily clinical practice by influencing the drugs' pharmacokinetics.

Cardiovascular and cerebrovascular risk with nonsteroidal anti-inflammatory drugs and cyclooxygenase 2 inhibitors: latest evidence and clinical implications.

Observational studies and meta-analyses have shown that the administration of nonsteroidal anti-inflammatory drugs (NSAIDs), especially when prescribed at high doses for long periods of time, can potentially increase the risk of cardiovascular diseases. The increased thrombotic risk related to the use of NSAIDs is mainly due to their cyclooxygenase 2 selectivity. The dosage use, the formulation selected and the duration of the therapy are other factors that can significantly impact on the cardiovascular risk.
