Randomized controlled trials are considered the hallmark of evidence-based medicine. This conveys the idea that up-to-date evidence applied consistently in clinical practice, in combination with clinicians' individual expertise and patients own preference/expectations are enjoined to achieve the best possible outcome. Since its inception in 1990s, evidence-based medicine has evolved in conjunction with numerous changes in the healthcare environment. ⋯ Further, both treatments were effective considering the baseline to 3 week and 6 week assessment, appropriate subgroup analysis seems to have yielded significant superiority for interlaminar epidural injections compared to transforaminal epidural injections with local anesthetic with or without steroids specifically with proportion of patients achieving greater than 50% improvement at 3 and 6 week levels. This critical assessment shows that this study suffers from a challenging design, was premised on the exclusion of available high-quality literature, and had inadequate duration of follow-up for an interventional technique with poor assessment criteria and reporting. Finally the analysis and interpretation of data has led to inaccurate and inappropriate conclusions which we do not believe is based on scientific evidence.

The increasing use of opioids to manage pain in the United States over the last decade has resulted in a subset of our population developing opioid tolerance. While the management of opioid tolerant patients during acute episodes of care is well known to be a challenge amongst health care providers, there is little in the literature that has studied opioid tolerance as a predictor of outcomes. We conducted a review on all admissions to Massachusetts General Hospital over a period of 6 months, from January 2013 to June 2013, and identified opioid tolerant patients at admission using the FDA definition of opioid tolerance. ⋯ This trend was found in the first 3 risk adjusted groups, but not in the fourth group where expected length of stay was greater than 10 days. The opioid tolerant population is at risk given the poorer outcomes and higher health care costs associated with their care. It is imperative that we identify opportunities for improvement and delineate specific pathways for the care of these patients.

Headache following head injuries has been reported for centuries. The majority of post-traumatic headache (PTH) patients will report resolution of their complaints within a few months from the time of the initial injury. PTHs can contribute to disability, lost productivity, and health care costs. ⋯ During 7 days of high cervical dorsal column electrical nerve stimulation trial, he reported almost 90% pain reduction and significant improvement on his quality of life. On 12 months follow-up after he underwent a permanent implant of high cervical dorsal column electrical nerve stimulation, he reported the same level of pain reduction along with 100% satisfaction rate. To the best of our knowledge, there have been no publications to date concerning the application of high cervical nerve stimulation for PTH.

Intrathecal drug delivery of opioids is an efficient and effective treatment option for pain management in the chronic nonmalignant pain population. As with all treatments, in addition to the benefits, risks and side effects exist. One such risk in intrathecal opioids is opioid-induced androgen deficiency. ⋯ Androgen deficiency is common in patients treated with intrathecal opioids for chronic nonmalignant pain. Patients experience numerous and wide ranging symptoms. Erectile dysfunction may be more suggestive for androgen deficiency in men while complaints of depressed mood may be correlative in women. Additionally, combining bupivicaine with the intrathecal opioid may provide a protective role.

Human umbilical cord mesenchymal stem cell transplantation for the treatment of chronic discogenic low back pain.
Chronic low back pain is one of the major causes of disability and thus has a major socioeconomic impact. Intervertebral disc degeneration is the main cause of chronic low back pain. Treatment for chronic discogenic low back pain has traditionally been limited to either conservative management or surgical fusion. If conservative treatment fails, then surgical fusion is commonly considered. Current treatments are limited to treat the symptoms and not the underlying biologic alterations of the disc. ⋯ The clinical outcomes indicated that HUC-MSC transplantation is a favorable alternative method for the treatment of chronic discogenic low back pain.
