Current pain and headache reports

Intracranial hypotension is known to occur as a result of spinal cerebrospinal fluid (CSF) leaking, which may be iatrogenic, traumatic, or spontaneous. Headache is usually, but not always, orthostatic. Spontaneous cases are recognized more readily than in previous decades as a result of a greater awareness of clinical presentations and typical cranial magnetic resonance imaging findings. ⋯ Surgery is reserved for cases that fail to respond or relapse after simpler measures. While the prognosis is generally good with intervention, serious complications do occur. More research is needed to better understand the genetics and pathophysiology of dural weakness as well as physiologic compensatory mechanisms, to continue to refine imaging modalities and treatment approaches, and to evaluate short- and long-term clinical outcomes.

ReviewRestless legs syndrome and pain disorders: what's in common?
Between 10 % and 30 % of the population report chronic pain. More than half of these also have sleep complaints. From considering these data, it can be inferred there is a significant overlapping between these conditions. ⋯ The potential shared mechanisms between RLS/WED and pain may involve sleep deprivation/fragmentation effect, inducing an increase in markers of inflammation and reduction in pain thresholds. These are modulated by several different settings of neurotransmitters with a huge participation of monoaminergic dysfunctional circuits. A thorough comprehension of these mechanisms is of utmost importance for the correct approach and treatment choices.

ReviewSufficiency and necessity in migraine: how do we figure out if triggers are absolute or partial and, if partial, additive or potentiating?
Migraine is, to a great extent, a genetically determined disorder and once it has manifested itself, it generally continues for years if not for decades. While the migraine is active, headaches can seemingly occur spontaneously but are often reportedly precipitated by events or factors, known as migraine triggers, the interplay of which is the topic of this paper. Among migraine triggers, the menstrual cycle is an important one that probably accounts for much of the excess of migraine in women compared with men. ⋯ Having identified trigger-headache associations, it needs to be determined which triggers are causative in the individual, either singly or in combination with others. This requires running an experiment with the individual that involves behavioral intervention to change exposure to a given trigger and determine whether that improves migraine. The ubiquitous adoption of the smart phone as a personal-data entry device, along with the possibility of bringing the results of sophisticated statistical analysis into the hands of patients and physicians, may well provide us with an important set of tools that will finally allow the unravelling of the age-old migraine-trigger puzzle.

ReviewWhat turns on a migraine? A systematic review of migraine precipitating factors.
Migraine attacks rarely occur spontaneously in the absence of any possible precipitating factors. A systematic literature review of 25 publications revealed a consistent set of stimuli that have been identified as factors associated with the onset of a migraine attack. The weighted average of the "Top 10" trigger factors was determined. ⋯ Future efforts aimed at mitigating these precipitating factors have the potential to significantly improve migraine management. However, the current healthcare system is unlikely to be able to develop detailed personalized management plans. There is a need to develop a novel approach to the identification and management of multiple trigger factors in individual migraineurs.

ReviewPrimary stabbing headache in adults and pediatrics: a review.
Primary stabbing headache (PSH) is an under-recognized primary headache disorder, which often goes undiagnosed. It is mainly characterized by its ultrashort stabbing quality and can be easily overlooked both by patients and providers as it is often not severe enough to interfere significantly with daily life. However, PSH may be severe and require therapy, and it is important for providers to recognize this headache type, both in adult and pediatric populations, as well as to be able to distinguish it from secondary headache disorders. PSH also may be more common than previously thought.
