Chemotherapy-induced painful peripheral neuropathy (CIPPN) affects up to 90% of cancer patients treated with chemotherapy agents. Despite the fact that it is relatively common, the underlying pathophysiology is still unclear and its treatment remains generic. Mechanisms of CIPPN are multifactorial, dependent on the specific chemotherapeutic agent used, and include multiple patient-related factors, including genetic factors that may predispose patients to either develop or not develop CIPPN. The purpose of this article is to review mechanisms, clinical signs and symptoms, diagnosis, treatment options, and prognosis for patients who develop CIPPN. We also offer research considerations for this complex and unpredictable phenomenon. ⋯ The management of CIPPN remains a clinical challenge for pain practitioners. As more research is being carried out to elucidate its pathophysiology and therapy, the innovative use of several non-traditional categories of drugs seems promising in the management of this complex phenomenon. Studies addressing predictability and possible genetic predisposition are necessary not only for preventive measures but also for targeted treatments.

ReviewPrevention of renal dysfunction in postoperative elderly patients.
To describe the effect of ageing on kidney function and to summarize the benefits of advocated measures to prevent perioperative acute kidney injury (AKI) in elderly patients. ⋯ The future increase in elderly patients being exposed to surgery calls for improved perioperative management to prevent collaterally increased AKI. Although pharmacological therapies aiming to protect the kidneys from harm are under evaluation, hemodynamic optimization and avoidance of nephrotoxic drugs, including HES and hyperchloremic solutions, are critical for the elderly perioperative patient.

Clinical TrialBedside monitoring of ventilation distribution and alveolar inflammation in community-acquired pneumonia.
It is unclear whether bedside monitoring tools such as exhaled nitric oxide measurements (FENO) and electrical impedance tomography (EIT) could help guiding patient management in community-acquired pneumonia (CAP). We hypothesized that exhaled NO would be increased in CAP patients and could be used to assess resolution of inflammation in the course of CAP therapy. Feasibility of multiple-breath (mb) and single-breath (sb) approach has been investigated. ⋯ EIT images at T2 showed a more homogeneous ventilation distribution in displayed EIT. FENO could be a prospective supplementary tool to describe local lung inflammation as individual trend parameter. EIT could be a suitable supplementary tool to monitor functional lung status in CAP.

Evaluative measurement properties of the patient-specific functional scale for primary shoulder complaints in physical therapy practice.
Clinical measurement, longitudinal. ⋯ These results suggest that the PSFS is a reliable, valid, and responsive instrument that can be used as an evaluative instrument in patients with a primary shoulder complaint.

Poincaré plot analysis of autocorrelation function of RR intervals in patients with acute myocardial infarction.
The Poincaré plot of RR intervals (RRI) is obtained by plotting RRIn+1 against RRIn. The Pearson correlation coefficient (ρRRI), slope (SRRI), Y-intercept (YRRI), standard deviation of instantaneous beat-to-beat RRI variability (SD1RR), and standard deviation of continuous long-term RRI variability (SD2RR) can be defined to characterize the plot. Similarly, the Poincaré plot of autocorrelation function (ACF) of RRI can be obtained by plotting ACFk+1 against ACFk. ⋯ The ρACF and SACF correlated significantly and negatively with normalized high-frequency power (nHFP), and significantly and positively with normalized very low-frequency power (nVLFP) of heart rate variability in both groups of patients. On the contrary, the RMSSDACF/SDACF and SD1ACF/SD2ACF correlated significantly and positively with nHFP, and significantly and negatively with nVLFP and low-/high-frequency power ratio (LHR) in both groups of patients. We concluded that the ρACF, SACF, RMSSDACF/SDACF, and SD1ACF/SD2ACF, among many other indices of ACF Poincaré plot, can be used to differentiate between patients with AMI and patients with PCA, and that the increase in ρACF and SACF and the decrease in RMSSDACF/SDACF and SD1ACF/SD2ACF suggest an increased sympathetic and decreased vagal modulations in both groups of patients.
