The purpose of this review is to evaluate the role of SPECT/CT in identifying facet joint arthropathy and the outcomes of interventions with SPECT/CT as an adjunct. ⋯ A positive finding of facet arthropathy on SPECT/CT is associated with a higher likelihood of a unilateral procedure and a significantly more effective intervention compared with those performed on patients with facet arthropathy diagnosed only by clinical and/or radiologic examination. Surgical treatment of SPECT/CT-positive findings appears to have a good effect; however, due to limitations in the available studies, no strong conclusion can be drawn. SPECT/CT has a good correlation identifying pain generators in chronic neck and back pain. SPECT/CT-targeted facet interventions demonstrate a higher success rate, but SPECT/CT is not recommended as a first-line diagnostic tool prior to diagnostic facet interventions. More robust studies are needed to confirm the higher success of surgical treatment for SPECT/CT-positive facet arthropathy.

ReviewSimulation-Based Education in Acute and Chronic Pain Training.
The use of simulation-based education (SBE) in medical training has expanded greatly and has grown to include high fidelity and task simulation along with hybrid models using patient actors to enhance education and training of critical events as well as technical skills. ⋯ In the field of anesthesiology, SBE has been particularly useful for crisis resource management and rare critical scenarios and new research into the use of SBE using task simulation for procedural skill development has been done highlighting the benefits to subspecialty procedural training. Medical simulation has become a common practice in medical training and research. SBE has demonstrated positive outcomes in improving technical skills, knowledge, comfort, and clinical performance. The widespread implementation of SBE in regional anesthesia and chronic pain training varies, with cost and availability being factors. Nonetheless, SBE has shown great potential in enhancing education and preparing physicians in subspecialties of anesthesia.

Review Case ReportsSpontaneous Intracranial Hypotension in Pregnancy.
Spontaneous intracranial hypotension (SIH) is a debilitating disease typically featuring orthostatic headache and caused by a spinal CSF leak. This review will describe the characteristics of SIH in pregnant patients and the associated unique management and treatment considerations. ⋯ Herein, a novel case is reported of a 41-year-old woman who presented with SIH pre-conception but saw marked improvement of symptoms after 5 weeks antepartum and symptom recurrence 2 months post-partum. A literature review of SIH in pregnancy revealed 14 reported patients across 10 studies since 2000. All the reported cases resulted in delivery of healthy infants and symptomatic improvement with conservative management or a variety of treatment modalities including non-targeted epidural blood patch (EBP). Clinical and imaging features of SIH in pregnancy are reviewed. We hypothesize an antenatal protective mechanism against SIH symptoms through cephalad redistribution of CSF volume from the spinal to intracranial compartments related to uterine growth and decreased CSF volume within the lumbar cistern. Treatment recommendations are discussed including duration of bed rest and decision for non-targeted multi-site EBPs. When required, non-invasive diagnostic spine MRI using fat-suppressed axial T2-weighted imaging may be helpful.

In this review article, we summarize the most recent findings and observations in patients experiencing primary cough headache. ⋯ Recent studies draw attention to further characterization of patients with primary cough headache in a pulmonology clinic. There have also been recent case studies describing new therapy considerations, including noninvasive vagus nerve stimulation and lumbar punctures. Primary cough headache has been a recognized entity since as early as 1932. Patients generally report a sudden onset, sharp headache lasting a few hours that is precipitated by Valsalva maneuver or coughing. It remains an uncommon diagnosis, and secondary causes are crucial to rule out with imaging studies. Additionally, there can be an overlap with other primary headache disorders such as primary exercise headache and headache associated with sexual activity, thus requiring a detailed history. Many hypotheses exist regarding the pathophysiology including relative pressure gradients and a crowded posterior fossa. Generally, patients are responsive to indomethacin, but more recent case reports have suggested benefits of other medications and procedures that may offer patients an alternative option, including vagus nerve stimulation, lumbar punctures, and beta blockers. Future case series and studies should focus on management of these patients, with a specific focus on individuals who do not tolerate indomethacin.
