Review Comparative StudyDoes Choice of Steroid Matter for Treatment of Chronic Low Back Pain with Sacroiliac Joint Injections: a Retrospective Study.
Prevalence of chronic low back pain (cLBP) is increasing. Sacroiliac joint (SIJ) is a common source of cLBP, but data behind its diagnosis and treatment is controversial. There is moderate quality evidence for effectiveness of therapeutic SIJ injections. However, there are no studies comparing the two most common steroid preparations, methylprednisolone (MTP) and triamcinolone (TAC) in SIJ injections. ⋯ Sixty-five percent of patients in the MTP group and 57% patients in the TAC group had >50% pain relief at 1-month follow-up, with no statistical difference between the two groups. Patients in the TAC group had significantly greater BMI and consisted of higher proportion of smokers (72% patients in TAC group versus 39% patients in the MTP group, p-value 0.004). Other sources of pain such as facet joints were unmasked post-procedurally after SIJ injections, with this unmasking being significant for the TAC group. Opiate use decreased in the MTP group from 35% pre-procedurally to 20% post-procedurally, and this difference did not reach statistical significance. Both MTP and TAC are effective in providing pain relief for SIJ pain at 1-month follow-up, with no statistical difference between the two types of steroids. Although not statistically significant, there is a modest reduction in opiate use in the MTP group.

ReviewStroke-Like Migraine Attacks After Radiation Therapy (SMART) Syndrome: A Comprehensive Review.
SMART syndrome is a delayed complication of cranial irradiation that can be misconstrued as tumor recurrence or some other intracranial neurological disease. Recognition of this clinical syndrome is imperative as it can obviate the need for invasive diagnostic testing and can provide reassurance to both the patient and their loved ones. ⋯ SMART syndrome is generally considered a reversible clinical syndrome; however, neurological deficits may become permanent. Pathophysiology of SMART syndrome may involve cerebrovascular autoregulation impairment, neuronal dysfunction leading to trigeminovascular system impairment and/or cortical spreading depression, and seizures. In addition to MRI brain with gadolinium, other imaging modalities, such as CT perfusion, MR perfusion, MR spectroscopy, and FDG PET/CT, aid in arriving to the diagnosis sooner. Patients should also undergo electroencephalogram in order to promptly identify and treat seizures. There are currently no clear guidelines on how to effectively treat SMART syndrome, but treatment may involve anti-seizure medication, anti-hypertensives, anti-platelet, and steroid therapy. This review provides a comprehensive understanding of the clinical characteristics of SMART syndrome from presentation to diagnostic evaluation. We also discuss radiographic features and treatment strategies for this rare disease. With increased radiotherapy utilization, prompt clinical recognition of SMART syndrome and further development of a comprehensive diagnostic approach to SMART syndrome utilizing newer radiographic modalities as well as treatment algorithms to effectively treat this clinical condition will be imperative.

ReviewDual Enkephalinase Inhibitors and Their Role in Chronic Pain Management.
Dual enkephalinase inhibitors (DENKIs) are pain medications that indirectly activate opioid receptors and can be used as an alternative to traditional opioids. Understanding the physiology of enkephalins and their inhibitors and the pharmacology of these drugs will allow for proper clinical application for chronic pain patients in the future. ⋯ DENKIs can be used as an alternative mode of analgesia for patients suffering from chronic pain by preventing the degradation of endogenous opioid ligands. By inhibiting the two major enkephalin-degrading enzymes (neprilysin and aminopeptidase N), DENKIs can provide analgesia with less adverse effects than nonendogenous opioids. The purpose of this paper is to review the current literature investigating DENKIs and explore their contribution to chronic pain management.

Review Case ReportsCarnitine Responsive Migraine Headache Syndrome: Case Report and Review of the Literature.
To review carnitine's role in migraine and headache, present a case of a patient with intractable chronic migraine refractory to medications but exquisitely responsive to mitochondrial cofactors with a particularly prompt response to L-carnitine supplementation with dose response, and suggest scenarios where L-carnitine could be considered for prophylactic treatment in migraine and intractable headache with migraine features. ⋯ Multiple treatments modalities are used to treat migraine, including nutraceutical therapies. Mitochondrial supplements are often used to treat migraine, based on controlled trials. One of the nutraceutical therapies used in neurological and non-neurological conditions is L-carnitine. A few studies have examined the effect of carnitine in patients with migraine. We present a case of a patient with chronic migraine-like headaches found to have carnitine deficiency whose headaches greatly improved with carnitine supplementation. This case suggests that secondary carnitine deficiency may cause chronic migraine. Energy deficiency states occur with migraine, and replenishment of energy substrates has demonstrated some improvement in migraine. Recent studies suggest that L-carnitine with other mitochondrial cofactors may be migraine preventives. The exact link between carnitine and migraine is unknown. Perhaps carnitine deficiency should be in the differential for refractory migraine. Supplementation with L-carnitine merits exploration as a nutraceutical treatment of chronic migraine. Our case suggests that there may be a dose-dependent response to L-carnitine.

ReviewConcussion in the Athletic Training Room: a Team Physician Narrative.
Concussion evaluation and management has changed significantly. Understanding proper recognition, evaluation, and management allows for improved provision of care to patients. This paper will approach this topic from a sideline to training room management versus the traditional clinic evaluation RECENT FINDINGS: Research is continuing to refine and examine tools to assist in proper concussion evaluation. ⋯ Treatment of concussion is becoming more sophisticated and patient involved. Concussion research has increased dramatically over the last 30 years changing our approach to diagnosis and treatment. The area of concussion will continue to evolve as research continues to look at effective tools and markers for diagnosis and effective treatment protocols become substantiated through research.
