Opioid-induced respiratory depression in the acute care setting: a compendium of case reports.
Opioid-induced respiratory depression (OIRD) is a potentially fatal complication of treatment with opioids. Little is known about patient- and case-related factors associated with OIRD. ⋯ The most frequently reported patient-related factors involved were: female gender, sleep-disordered breathing, obesity, renal impairment, pulmonary disease and CYP450 enzyme polymorphisms. While the analysis has limitations, it confirms that OIRD in the acute setting involves complex and interrelated factors and is a significant cause of preventable morbidity and mortality.

Both primary headaches and minor head injuries are common in children. If headache presents for the first time or becomes exacerbated soon after head injury it is described as post-traumatic headache (PTH). Acute PTH resolves within 3 months from injury, but chronic PTH continues beyond 3 months. ⋯ Several mechanisms were proposed such as axonal injuries and disturbances of cerebral metabolic processes. The clinical features of PTH are those of primary headache disorders such as migraine and tension-type headache and usually follow a favorable prognosis. Investigations and management should therefore be relevant to the type of headache and focused on clinical needs of the child.

Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological intervention that activates a complex neuronal network to reduce pain by activating descending inhibitory systems in the central nervous system to reduce hyperalgesia. The evidence for TENS efficacy is conflicting and requires not only description but also critique. ⋯ The purpose of this article is to provide a critical review of the latest basic science and clinical evidence for TENS. Additional research is necessary to determine if TENS has effects specific to mechanical stimuli and/or beyond reduction of pain and will improve activity levels, function and quality of life.

Neuropathic pain affects 6-8% of the general adult population. It is reported by 27% of chronic pain patients and 40% of cancer patients, yet there is no standardized diagnostic test for neuropathic pain. ⋯ Over the past decade these neuropathic pain screening tools have been validated in a wide range of pain populations, as well as translated into many languages, to discriminate between neuropathic and non-neuropathic pain. We describe here the five most commonly used neuropathic pain screening tools and discuss current assessment guidelines, the use of screening tools in novel clinical contexts and their potential use in personalized therapy.

A recent revision in the definition of neuropathic pain has highlighted this condition as a distinct disease entity. More accurate search for a lesion in the somatosensory nervous system as the pain-generating mechanism will help target the treatment by pharmacological agents. A multidisciplinary approach is recommended, with pharmacotherapy supplemented by psychological therapy and physical rehabilitation, and appropriate interventional treatment for selected refractory cases.
