Intraoperative hypotension is associated with adverse outcomes. The preferred treatment for intraoperative hypotension is to address its cause. In the interim the blood pressure can be supported by the anesthesia team with volume resuscitation and vasopressors. ⋯ Therefore we propose bilateral femoral artery compression as a new technique to increase vital organ perfusion during intraoperative hypotension. This results in shunting of blood flow from the legs and towards the vital organs. Bilateral femoral artery compression can be employed by the surgical team to immediately improve blood pressure until other counter-measures against intraoperative hypotension take effect.

Fibromyalgia is a most common pain syndrome characterized by the presence of chronic widespread pain and tenderness with manual palpation. However there is no enough data about frequent of fibromyalgia syndrome in patients with cancer. ⋯ In conclusion, there is it may more prevalence of fibromyalgia in patients with cancer. For the diagnosis of fibromyalgia, be new diagnostic criteria for early-stage cancer patients.

The assessment of critically ill patients is often a challenge for clinicians. There are a number of scoring systems such as Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) and C-reactive protein test (CRP), which have been shown to correlate with outcome in a variety of Intensive Care Unit (ICU) patients. Therefore, use of repeated measures of these preexisting scores over time is a reasonable attempt to assess the severity of organ dysfunction and predict outcome in critically ill patients. Several reports suggest that the neutrophil is a useful marker of sepsis. However, since both a large number and a small number of neutrophils indicate a severe situation, neutrophil count is difficult to use to directly predict patients'. ⋯ Based on these preliminary evaluations, we hypothesize that n-score may be a useful scoring system to detect risk of death in sepsis and severe sepsis/septic shock.

Chronic pain is often managed using a multidisciplinary, biopsychosocial approach. Interventions targeting the biological, psychological, and social aspects of both the patient and the pain have been demonstrated to provide objective and subjective improvement in chronic pain symptoms. ⋯ Using as a model the unique case of Mr. S, a patient suffering with chronic pain for 22 years who experienced a complete resolution of pain after a lucid dream following 2 years of biopsychosocial treatments, we postulate that central nervous system (CNS) reorganization (i.e., neural plasticity) serves as a possible mechanism for the therapeutic benefit of multidisciplinary treatments, and may set a neural framework for healing, in this case via a lucid dream.

We propose a hypothesis for predicting addictive potential of oral drugs, in general, and oxycodone's addictive potential, in particular. We hypothesize that a patient's CYP2D6 phenotype determines oxycodone's addictive potential, in part, via genotype-specific regulation of its clearance; although, other possible modulators of oxycodone's addiction potential exist. ⋯ Using CYP2D6 phenotype-specific oxycodone pharmacokinetic parameter values derived from published data, our hypothesis predicted that the canonical order of oxycodone's addictive potential was UM>EM>IM>PM, with corresponding LAP values of 0.24, 0.21, 0.17, and 0.15 respectively. Our hypothesis about oxycodone's addictive potential may provide a unifying approach useful for both personalized medicine dosing and predicting addictive potential of oral drugs in humans, since it is based on both oxycodone's pharmacogenetics and pharmacokinetics.
