Post-traumatic stress symptoms in Guillain-Barré syndrome patients after prolonged mechanical ventilation in ICU: a preliminary report.
Thirty percent of Guillain-Barré syndrome (GBS) patients require mechanical ventilation (MV) in intensive care unit (ICU). Post-traumatic stress disorder (PTSD) is found in ICU survivors, and the traumatic aspects of intubation and MV have been previously reported as risk factors for PTSD after ICU. Our objective was to determine long-term PTSD or post-traumatic stress symptoms (PTSS) in GBS patients after prolonged MV in ICU. ⋯ Compared with the French population, the SF-36 sub-categories were, however, not statistically different. Twenty-two percentage of our 13 patients had PTSD and PTSS with a Horowitz IES at 12 (2-29), and an IES-R at 16 (2-34.5). Although severe GBS patients requiring prolonged MV had good functional recovery and no difference in QoL, they had a high incidence of PTSS.

ReviewPainful neuropathies: the emerging role of sodium channelopathies.
Pain is a frequent debilitating feature reported in peripheral neuropathies with involvement of small nerve (Aδ and C) fibers. Voltage-gated sodium channels are responsible for the generation and conduction of action potentials in the peripheral nociceptive neuronal pathway where NaV 1.7, NaV 1.8, and NaV 1.9 sodium channels (encoded by SCN9A, SCN10A, and SCN11A) are preferentially expressed. The human genetic pain conditions inherited erythromelalgia and paroxysmal extreme pain disorder were the first to be linked to gain-of-function SCN9A mutations. ⋯ Peripheral neuropathies may not always be length-dependent, as demonstrated in patients with initial facial and scalp pain symptoms with SCN9A mutations showing hyperexcitability in both trigeminal ganglion and DRG neurons. There is some evidence suggesting that gain-of-function SCN9A mutations can lead to degeneration of peripheral axons. This review will focus on the emerging role of sodium channelopathies in painful peripheral neuropathies, which could serve as a basis for novel therapeutic strategies.

ReviewChemotherapy-induced peripheral neurotoxicity (CIPN): what we need and what we know.
Chemotherapy-induced peripheral neurotoxicity (CIPN) is one of the most frequent and severe long-term side effects of cancer chemotherapy. Preclinical and clinical studies have extensively investigated CIPN searching for effective strategies to limit its severity or to treat CIPN-related impairment, but the results have been disappointing. ⋯ Among the several neurotoxic chemotherapy drugs, oxaliplatin may offer a clear example of a methodological approach eventually leading to successful clinical trials. However, the same considerations apply to the other neurotoxic agents and, although frequently neglected, also to the new "targeted" agents.
