Migraine headache is commonly associated with signs of exaggerated intracranial and extracranial mechanical sensitivities. Patients exhibiting signs of intracranial hypersensitivity testify that their headache throbs and that mundane physical activities that increase intracranial pressure (such as bending over or coughing) intensify the pain. Patients exhibiting signs of extracranial hypersensitivity testify that during migraine their facial skin hurts in response to otherwise innocuous activities such as combing, shaving, letting water run over their face in the shower, or wearing glasses or earrings (termed here cephalic cutaneous allodynia). Such patients often testify that during migraine their bodily skin is hypersensitive and that wearing tight cloth, bracelets,rings, necklaces and socks or using a heavy blanket can be uncomfortable and/or painful (termed her extracephalic cutaneous allodynia). This review summarizes the evidence that support the view that activation of the trigeminovascular pathway contribute to the headache phase of a migraine attack, that the development of throbbing in the initial phase of migraine is mediated by sensitization of peripheral trigeminovascular neurons that innervate the meninges, that the development of cephalic allodynia is propelled by sensitization of second-order trigeminovascular neurons in the spinal trigeminal nucleus which receive converging sensory input from the meninges as well as from the scalp and facial skin, and that the development of extracephalic allodynia is mediated by sensitization of third-order trigeminovascular neurons in the posterior thalamic nuclei which receive converging sensory input from the meninges, facial and body skin.

Objective The United States is currently in the midst of a major opioid addiction epidemic, of which the primary drivers are a sharp increase in prescription opioid pain medications, their misuse, and the inordinate illicit use of opioids. Declared a national health emergency, the opioid crisis puts enormous pressure on various systems, including increasing overcrowding in emergency departments (EDs) and forced changes in prescribing practices. We are piloting a newly-developed ED opiate pathway to streamline ED care for patients who frequently present at the ED for chronic pain management or other recurrent pain-causing medical problems. Methods Patients at risk of possible opioid addiction are identified and their records are reviewed. If there is no narcotics agreement in place, the ED care team contacts the primary care physician and any other service providers involved in the patient’s care to create a comprehensive pain management program. Results Our pathway is simple and geared toward streamlining and improving care for patients with opioid addiction and misuse. We looked at seven patients in this pilot study with mixed results regarding decreasing future ED visits. Conclusion This strategy may both limit opioid usage and abuse as well as limit ED visits and overcrowding by streamlining ED care for patients who frequently present for chronic pain management or other recurrent medical problems.

Hot Populations in M87 Globular Clusters
Sohn, Sangmo T.,O'Connell, Robert W.,Kundu, Arunav,Landsman, Wayne B.,Burstein, David,Bohlin, Ralph C.,Frogel, Jay A.,Rose, James A. American Institute of Physics 2006 The Astronomical journal Vol.131 No.2
<P>To explore the production of UV-bright stars in old, metal-rich populations like those in elliptical galaxies, we have obtained Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph far- and near-UV photometry of globular clusters (GCs) in four fields in the giant elliptical (gE) galaxy M87. To a limit of m<SUB>FUV</SUB> ~ 25 we detect a total of 66 GCs in common with the deep HST optical-band study of Kundu et al. Despite strong overlap in V- and I-band properties, the M87 GCs have UV-optical properties that are distinct from clusters in the Milky Way and in M31. M87 clusters, especially metal-poor ones, produce larger hot horizontal-branch populations than do Milky Way analogs. In color plots including the near-UV band, the M87 clusters appear to represent an extension of the Milky Way sequence. Cluster mass is probably not a factor in these distinctions. The most metal-rich M87 GCs in our sample are near solar metallicity and overlap the local E galaxy sample in estimated Mg<SUB>2</SUB> line indices. Nonetheless, the clusters produce much more UV light at a given Mg<SUB>2</SUB>, being up to 1 mag bluer than any gE galaxy in (FUV - V) color. The M87 GCs do not appear to represent a transition between Milky Way-type clusters and E galaxies. The differences are in the correct sense if the clusters are significantly older than the E galaxies.</P><P>Comparisons with Galactic open clusters indicate that the hot stars lie on the extreme horizontal branch, rather than being blue stragglers, and that the extreme horizontal branch becomes well populated for ages ≳5 Gyr. Existing model grids for clusters do not match the observations well, due to poorly understood giant branch mass loss or perhaps high helium abundances. We find that 41 of our UV detections have no optical-band counterparts. Most appear to be UV-bright background galaxies seen through M87. Eleven near-UV variable sources detected at only one epoch in the central field are probably classical novae. Two recurrent variable sources have no obvious explanation but could be related to activity in the relativistic jet.</P>
