Observational Study
Insulin Resistance is Associated with Central Pain in Patients with Fibromyalgia.
Insulin resistance (IR) is a pathological condition in which cells fail to respond normally to insulin. IR has been associated with multiple conditions, including chronic pain. Fibromyalgia (FM) is one of the common generalized chronic painful conditions with an incidence rate affecting 3% to 6% of the population. Substantial interest and investigation into FM continue to generate many hypotheses.The relationship between IR and FM has not been explored. IR is known to cause abnormalities in the cerebral microvasculature, leading to focal hypoperfusion. IR also has been shown to cause cognitive impairment in FM patients, as in parkinsonism. As demonstrated by advanced imaging methods, similar brain perfusion abnormalities occur in the brain of patients with FM as with IR. ⋯ The association demonstrated in this study warrant further investigation, including the pursuit of randomized, double-blind clinical trials to determine the effect of improving insulin sensitivity in FM related pain scores. Such studies could unveil a potential pathogenetic relationship between FM, central pain, and IR. Based on these initial findings, we present the hypothesis that IR may underlie pathological mechanisms leading to central pain. If confirmed, this may lead to a paradigm shift in the management of central pain.

Cerebrospinal fluid (CSF) leakage resulting in post dural puncture headache (PDPH) is a frequent adverse effect observed after intrathecal drug delivery system (IDDS) implantation. CSF leakage symptoms negatively affect patient quality of life and can result in additional complications. Fibrin glue was used to treat CSF leakage syndrome. We developed a procedure to reduce the incidence of PDPH by preventing CSF leakage with the use of fibrin glue during surgery. ⋯ The novel use of fibrin glue is promising in terms of its effect on PDPH and its safety profile. Its moderate cost and reproducibility make it an affordable and efficient technique.

Opioid abuse has been an increasing problem since the 1990s. With over 47,000 opioid related deaths recorded in 2017 alone, concerns have been raised regarding the dangers of introducing opioids perioperatively to patients undergoing major surgeries. ⋯ Prescription opioid misuse is more common among the black population. The total opioid consumption is frequently lower than the quantity prescribed. Patients frequently use opioids even though they feel that pain is insufficient to deserve such an intervention. Euphoria is experienced by a significant number of patients taking prescription opioids Often patients do not take any opioids, although they had prescriptions.

Vertebroplasty and kyphoplasty are leading treatments for patients with vertebral body compression fractures. Although cement augmentation has been shown to help relieve pain and instability from fractures containing a cleft, there is some controversy in the literature regarding the procedure's efficacy in these cases. Additionally, some of the literature blurs the distinction between clefts and cement patterns (including cement nonunion and cement fill pattern). Both clefts and cement patterns have been mentioned in the literature as risks for poorer outcomes following cement augmentation, which can result in complications such as cement migration. ⋯ Vertebral body fracture clefts are not uncommon and are related to (but distinct from) cement nonunion and cement fill patterns. Our study shows that, although patients with clefts will benefit from cement augmentation just as much as patients without a cleft, the performing provider should take note of cement fill and take extra steps to ensure optimal cement fill. These providers should also identify cement nonunion and associated complications (such as cement migration) on follow-up imaging.
