We retrospectively assessed the postoperative clinical outcomes of balloon kyphoplasty (BKP).

: Dental pain is primarily treated by dentists and emergency medicine clinicians and may occur because of insult to the tooth or oral surgery. The dental impaction pain model (DIPM) has been widely used in clinical studies of analgesic agents and is generalizable to many other forms of pain.: The authors discuss the DIPM, which has allowed for important head-to-head studies of analgesic agents, such as acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and combinations. Postsurgical dental pain follows a predictable trajectory over the course of one to 3 days. Dental pain may have odontic origin or may be referred pain from other areas of the body.: Pain following oral surgery has sometimes been treated with longer-than-necessary courses of opioid therapy. Postsurgical dental pain may be moderate to severe but typically resolves in a day or two after the extraction. Opioid monotherapy, rarely used in dentistry but combination therapy (opioid plus acetaminophen or an NSAID), was sometimes used as well as nonopioid analgesic monotherapy. The dental impaction pain model has been valuable in the study of analgesics but does not address all painful conditions, for example, pain with a neuropathic component.

Pre-exposure to volatile anesthetics inhibits inflammation induced by various stimuli, including surgical procedures and ischemia. The authors hypothesized that volatile anesthetics may induce anti-inflammatory effects via a mechanism involving regulation of histone deacetylases (HDACs). Pre-exposure of 1.5% isoflurane for 0.5 h induced anti-inflammatory effects (measured by cytokine production of TNF-ɑ, IL-8, and IL-1β) in both human THP-1 cells and primary human peripheral blood monocytes stimulated by lipopolysaccharide. In human THP-1 cells, co-administration of the HDAC inhibitor trichostatin A blocked the isoflurane-induced anti-inflammatory effects. Trichostatin A also blocked isoflurane-upregulated HDAC1-3 expression and isoflurane-reduced nuclear translocation of p65 and p50 subunits of NF-κB. The ability of isoflurane to reduce NF-κB nuclear translocation and pro-inflammatory responses in the cell line were blocked by gene-silencing of HDAC1 and HDAC2, but not by gene-silencing of HDAC3. A co-immunoprecipitation (co-IP) assay demonstrated that the decreased interaction between HDAC1 and HDAC2 through lipopolysaccharide was restored by isoflurane pre-treatment. These findings were validated in primary human peripheral blood monocytes wherein gene-silencing of HDAC1 and HDAC2 resulted in increased cytokine production and NF-κB nuclear translocation induced by isoflurane pre-exposure and LPS stimulation. These results indicate that anti-inflammatory effects of the volatile anesthetic isoflurane in human monocytes involve regulation of HDAC1 and HDAC2.

Infratentorial multinodular lesions resembling Multinodular and Vacuolating Neuronal Tumor of the cerebrum (MVNT) have been indicated in literature with two different names reflecting alternative perspectives: "Multinodular and Vacuolating Posterior Fossa Lesions of Unknown Significance (MV-PLUS)", suggesting that these lesions may belong to a new entity, and "MVNT of the brain", assuming that they actually correspond to infratentorial MVNT. Due to the limited number of cases reported and the absence of histopathological data, it is presently uncertain which denomination should be used.

We present the case of a patient who presented to the emergency department complaining of diffuse myalgias, severe jaw pain and chills. She met criteria for severe sepsis and received treatment including analgesia, antibiotics, intravenous fluids, and antipyretics. Workup revealed an elevated lactate and leukocytosis however, did not reveal any infectious source. The patient had a history of Crohn's disease and had received an infusion of infliximab ten days prior to the onset of her symptoms. After ruling out other potential causes of lactic acidemia, her final diagnosis was determined to be the rare presentation of an infliximab infusion reaction. On reviewing the literature, we could not find another documented case of a lactic acidemia caused by an infliximab infusion reaction. The key to the treatment of this patient was steroids, antihistamines, and supportive treatment. Emergency physicians do not often encounter infliximab infusion reactions because they occur so infrequently. Along with more common diagnoses such as sepsis, emergency physicians should include infliximab infusion reactions on the differential diagnosis in patients receiving this medication.

This study was designed to investigate the effect of nano-curcumin supplementation on pentraxin 3 (PTX3) gene exp ression and serum level in migraine patients.

Adequate pain control is essential following lung transplantation to reduce patient stress and minimize perioperative complications. Enhanced recovery after surgery (ERAS) protocols have demonstrated improvements in patient experience and reduced length of stay. However, the implementation of these protocols has not yet extended to the lung transplant population.

Knee osteoarthritis (OA) is a common joint disease causing chronic pain and functional alterations (stiffness and swelling) in the elderly population. OA is currently treated pharmacologically with analgesics, although neuromodulation via transcranial direct current stimulation (tDCS) has recently generated a growing interest as a safe side-effect free treatment alternative or a complement to medications for chronic pain conditions. Although a number of studies have shown that tDCS has a beneficial effect on behavioral measures of pain, the mechanistic action of neuromodulation on pain sensitivity and coping at the central nervous system is not well understood. We aimed at observing longitudinal changes of cortical hemodynamics in older adults with knee OA associated with a two-week-long tDCS self-treatment protocol. Hemodynamics was measured bilaterally in the motor and somatosensory cortices with functional near-infrared spectroscopy (fNIRS) in response to thermal pain induced ipsilaterally to the knee primarily affected by OA. We found that both oxyhemoglobin- and deoxyhemoglobin-related functional activations significantly increased during the course of the tDCS treatment, supporting the notion that tDCS yields an increased cortical excitability. Concurrently, clinical measures of pain decreased with tDCS treatment, hinting at a potential spatial dissociation between cortically mediated pain perception and suppression and the prevalence of neuromodulatory effects over cortical pain processing. fNIRS is a valid method for objectively tracking pain in an ambulatory setting and it could potentially be used to inform strategies for optimized tDCS treatment and to develop innovative tDCS protocols.

China's universal two-child policy was released in October of 2015. How would this new policy influence the rate of overall cesarean delivery (CD) in China? The objective of this paper is to investigate the trend of overall CD rate with the increase of number of multiparous women based on a big childbirth center of China (a tertiary hospital) in 2016. In this study, 22 530 cases from the medical record department of a big childbirth center of China from January 1 to December 31 in 2016 were enrolled as research objects. Electronic health records of these selected objects were retrieved. According to the history of childbirth, the selected cases were divided into primiparous group containing 16 340 cases and multiparous group containing 6190 cases. Chi-square test was carried out to compare the rate of CD, neuraxial labor analgesia, maternity insurance between the two groups; t-test was performed to compare the in-hospital days and gestational age at birth between the two groups. Pearson correlation coefficient was used to evaluate the relationship among observed monthly rate of multiparas, overall CD rate, and Elective Repeat Cesarean Delivery (ERCD) rate. The results showed that the CD rate in multiparous group was 55.46%, which was higher than that in primiparous group (34.66%, P<0.05). The rate of neuraxial labor analgesia in multiparas group was 9.29%, which was lower than that in primiparas group (35.94%, P<0.05). However, the rate of maternity insurance was higher in multiparas group (57.00%) than that in primiparas group (41.08%, P<0.05). The hospital cost and in-hospital days in multiparas group were higher, and the gestational age at birth in multiparas group was lower than in primiparas group (P<0.05). The overall CD rate slightly dropped in the first 4 months of the year (P<0.05), then increased from 36.27% (April) to 43.21% (December) (P<0.05). The rate of multiparas women and ERCD had the same trend (P<0.05). There were linear correlations among the rate of overall CD, the rate of multiparas women and the rate of ERCD rate (P<0.05). With the opening of China's two-child policy, the increasing rate of overall CD is directly related with the high rate of ERCD. Trials of Labor After Cesarean Section (TOLAC) in safe mode to reduce overall CD rate are warranted in the future.

SPN-812 (extended-release viloxazine) is a structurally distinct, bicyclic, Serotonin Norepinephrine Modulating Agent (SNMA) in development as a treatment for attention-deficit/hyperactivity disorder (ADHD) in children and adolescents. This Phase 3, randomized, double-blind study (P303) evaluated the efficacy and safety of once-daily SPN-812 at doses of 200 and 400 mg compared to placebo in children ages 6-11yrs with ADHD.
