Headache
-
Post-dural puncture headache (PDPH) is a frequent complication of dural puncture whether performed for diagnostic purposes or accidentally, as a complication of anesthesia. Because both procedures are common, clinicians interested in headache should be familiar with this entity. The differential diagnosis of PDPH is broad and includes other complications of dural puncture as well as headaches attributable to the condition which lead to the procedure. ⋯ Finally, despite best preventive efforts, PDPH may still occur and be associated with significant morbidity. Therefore, it is important to know the management and prognosis of this disorder. In this review, we will highlight diagnosis and clinical characteristics of PDPH, differential diagnosis, frequency, and risk factors as well as pathophysiology of PDPH.

Review Practice Guideline
A practice guide for continuous opioid therapy for refractory daily headache: patient selection, physician requirements, and treatment monitoring.
To provide a guide to the use and limitations of continuous opioid therapy (COT, or daily scheduled opioids) for refractory daily headache, based on the best available evidence and expert clinical experience. ⋯ Only a select and very limited group (estimate of 10-20%) of refractory headache patients who meet criteria for COT respond with convincing headache reduction and functional improvement over the long-term. Conservative and empirically based guidelines will help identify those patients for whom a COT trial may be appropriate, while protecting their welfare and safety.

Case Reports Clinical Trial
Electrical stimulation of sphenopalatine ganglion for acute treatment of cluster headaches.
Cluster headaches (CH) are primary headaches marked by repeated short-lasting attacks of severe, unilateral head pain and associated autonomic symptoms. Despite aggressive management with medications, oxygen therapy, nerve blocks, as well as various lesioning and neurostimulation therapies, a number of patients are incapacitated and suffering. The sphenopalatine ganglion (SPG) has been implicated in the pathophysiology of CH and has been a target for blocks, lesioning, and other surgical approaches. For this reason, it was selected as a target for an acute neurostimulation study. ⋯ Sphenopalatine ganglion stimulation can be effective in relieving acute severe CH pain and associated autonomic features. Chronic long-term outcome studies are needed to determine the utility of SPG stimulation for management and prevention of CH.

Diet and lifestyle are seen as factors which influence headache in adults. However, population-based studies on this issue in adolescents are rare. ⋯ Adolescents with any type of headache might benefit from regular physical activity and low consumption of alcoholic drinks, while for migraine patients a low consumption of coffee should additionally be recommended. Intervention studies are warranted to assess whether psycho-educational programs conferring knowledge of these associations will influence headache-triggering behavior and headache in adolescents.
