Objective To report a case series of a novel migraine subtype, which we term as episodic status migrainosus (ESM), characterized by attacks of migraine exclusively lasting more than 72 hours. We hypothesized that this would represent a novel nosologic entity, possibly an unstable migraine phenotype with a high conversion rate to chronic migraine (CM). Methods We conducted a retrospective review of patients diagnosed with status migrainosus at the Mayo Clinic, Rochester, between January 2005 and December 2015. All the records were then manually reviewed for patients with migraine headaches exclusively lasting more than 72 hours. Results We identified 18 patients with ESM, with a female predominance (15(83.3%)) and a median age of onset of 16.5 (IQR 13–19) years. The median monthly attack frequency was two (IQR 1–3), with each attack lasting a median duration of seven (IQR 4–12.5) days. Stress was the most commonly reported precipitant (11 (61.1%)). Migraine with aura was common (10 (55.6%)), as was comorbid depression (10 (55.6%)). Fifteen (83.3%) patients developed CM at a median of 7.8 (IQR 2.6–21.9) years from their first attack. There was no significant association between the time to the development of chronic migraine with either attack frequency or duration. Conclusions and relevance We report the existence of a novel migraine subtype, episodic status migrainosus. This migraine subtype appears to have similar clinical characteristics to episodic migraine with or without aura, except for a notably high tendency to progress to chronic migraine.

ABSTRACTIntroductionPolyneuropathy signs (Neuropathy Impairment Score, NIS), neurophysiologic tests (m+7Ionis), disability, and health scores were assessed in baseline evaluations of 100 patients entered into an oligonucleotide familial amyloidotic polyneuropathy (FAP) trial.MethodsWe assessed: (1) Proficiency of grading neurologic signs and correlation with neurophysiologic tests, and (2) clinometric performance of modified NIS+7 neurophysiologic tests (mNIS+7Ionis) and its subscores and correlation with disability and health scores.ResultsThe mNIS+7Ionis sensitively detected, characterized, and broadly scaled diverse polyneuropathy impairments. Polyneuropathy signs (NIS and subscores) correlated with neurophysiology tests, disability, and health scores. Smart Somatotopic Quantitative Sensation Testing of heat as pain 5 provided a needed measure of small fiber involvement not adequately assessed by other tests.ConclusionsSpecially trained neurologists accurately assessed neuropathy signs as compared to referenced neurophysiologic tests. The score, mNIS+7Ionis, broadly detected, characterized, and scaled polyneuropathy abnormality in FAP, which correlated with disability and health scores. Muscle Nerve 56: 901–911, 2017

AbstractBackgroundTransthoracic echocardiography (TTE) and computerized axial tomography (CT) are complementary imaging techniques. It is possible that a combination of the two may offer a better way of identifying pulmonary hypertension (PH) than either one alone.ObjectivesTo determine the diagnostic accuracy of TTE combined with chest CT in pulmonary hypertension.MethodsWe performed a retrospective review of consecutive patients who had undergone TTE, CT and right heart catheterization (RHC) between 7/1/2008 and 6/30/2012. PH was defined as systolic pulmonary artery pressure >40 mm Hg or tricuspid regurgitant (TR) jet velocity >2.8m/s on TTE, ratio of diameter of pulmonary artery to ascending aorta (rPA) >1 or diameter of PA (dPA) >30 mm on CT, and mean PAP (mPAP) >25 mm Hg on RHC.ResultsThere was a total of 87 patients. The mean ± SD age was 54.3 ± 15.9 years and 69 (79%) were female. The prevalence of PH was 75%. The mean ± SD mPAP was 35.8 ± 14.2 mm Hg. The majority of the patients belonged to World Health Organization group I PH. Fifty per cent of the CT scans were done with intravenous contrast dye. The combination of TR jet velocity and rPA provided the best combination of sensitivity (98%) and specificity (70%) with an ROC area under the curve of 0.84.ConclusionThe combination of TTE and chest CT is better than either imaging technique alone in identifying patients with PH in a heterogeneous population and may exclude PH

Objectives We aimed to determine the rates of readmission and reoperation for patients undergoing surgery for pelvic organ prolapse (POP). Methods The American College of Surgeons National Surgical Quality Improvement Program Participant User File was used to select all surgeries performed for POP from 2012 through 2014. The cohort was then reviewed for unplanned readmissions and unplanned reoperations within 30 days of POP surgery. Patient and procedural factors associated with readmission or reoperation were compared using χ2 analyses and Student t test. Multivariable logistic regression determined independent risk factors for both readmission and reoperation. Results A total of 23,419 patients underwent surgery for POP. Of these, there were 435 (1.9%) readmissions and 341 (1.5%) reoperations within 30 days. Median numbers of days from index procedure to readmission or reoperation were 9 and 8 days, respectively. Those who were readmitted had higher American Society of Anesthesia (ASA) scores, longer operative times, and longer lengths of stay than those who were not readmitted (all P < 0.001). Patients who underwent unplanned reoperation also had higher ASA scores, longer operative times, and longer lengths of stay than those who did not undergo reoperation (all P < 0.01). The most common reasons for readmission were surgical site infection (SSI) (19.3%) and non-SSI (15.9%). The most common reason for reoperation was urologic (27.6%) such as cystoscopy or stent placement. Conclusions Readmission and reoperation rates are relatively low for patients undergoing surgery for POP. Infection, both SSI and non-SSI, accounted for 35.2% of readmissions. Identification of ASA score of 3 or higher, longer total operating time, and increased length of stay is associated with unplanned readmission and reoperation.

Objective. HIV and sexually transmitted disease (STD) surveillance patterns in Arizona suggested the need for integrated data analyses to identify trends. Methods. We compiled all HIV/AIDS cases diagnosed from 1998 to 2008 that were reported in Arizona and syphilis or gonorrhea cases diagnosed from 1998 to 2008 in Arizona. We used deterministic matching to identify individuals who were diagnosed with HIV and one or more STDs, and calculated time intervals between diagnoses. Results. Of 23,940 people with HIV/AIDS reported from 1998 to 2008, 1,899 (2.6%) had at least one syphilis or gonorrhea diagnosis from 1998 to 2008. Approximately 85% of these cases reported male-to-male sexual contact. Among males with syphilis, HIV coinfection increased from 0.5% in 1998 to 29.1% in 2008. Among males with gonorrhea, HIV coinfection increased from 2.0% in 1998 to 3.1% in 2008. Among HIV cases diagnosed from 2004 to 2008 and reported with at least one syphilis or gonorrhea diagnosis, the majority of syphilis cases (76.1%) were diagnosed at or after HIV diagnosis, whereas a majority of gonorrhea cases (54.9%) were diagnosed prior to HIV diagnosis. Conclusion. Use of the deterministic matching method identified increases in STD infections among HIV-infected people. The routine performance of this cross-matching method may be a useful tool in identifying these high-risk individuals so that targeted partner services and appropriate care referrals may be used in a timely fashion.

ABSTRACT The glutamic acid decarboxylase 65‐kilodalton isoform (GAD65) antibody is a biomarker of autoimmune central nervous system (CNS) disorders and, more commonly, nonneurological autoimmune diseases. Type 1 diabetes, autoimmune thyroid disease, and pernicious anemia are the most frequent GAD65 autoimmune associations. One or more of these disorders coexists in approximately 70% of patients with GAD65 neurological autoimmunity. Neurological phenotypes have CNS localization and include limbic encephalitis, epilepsy, cerebellar ataxia, and stiff‐person syndrome (SPS), among others. Classic SPS is a disorder on the spectrum of CNS hyperexcitability which also includes phenotypes that are either more restricted (stiff‐limb syndrome) or more widespread (progressive encephalomyelitis with rigidity and myoclonus). GAD65 antibody is not highly predictive of a paraneoplastic cause for neurological disorders, but diverse cancer types have been occasionally reported. For all phenotypes, responses to immunotherapy are variable (approximately 50% improve). GAD65 autoimmunity is important to recognize for both coexisting nonneurological autoimmune associations and potential immunotherapy‐response. Muscle Nerve 56 : 15–27, 2017

Various pathophysiological conditions such as surfactant dysfunction, mechanical ventilation, inflammation, pathogen products, environmental exposures, and gastric acid aspiration stress lung cells, and the compromise of plasma membranes occurs as a result. The mechanisms necessary for cells to repair plasma membrane defects have been extensively investigated in the last two decades, and some of these key repair mechanisms are also shown to occur following lung cell injury. Because it was theorized that lung wounding and repair are involved in the pathogenesis of acute respiratory distress syndrome (ARDS) and idiopathic pulmonary fibrosis (IPF), in this review, we summarized the experimental evidence of lung cell injury in these two devastating syndromes and discuss relevant genetic, physical, and biological injury mechanisms, as well as mechanisms used by lung cells for cell survival and membrane repair. Finally, we discuss relevant signaling pathways that may be activated by chronic or repeated lung cell injury as an extension of our cell injury and repair focus in this review. We hope that a holistic view of injurious stimuli relevant for ARDS and IPF could lead to updated experimental models. In addition, parallel discussion of membrane repair mechanisms in lung cells and injury-activated signaling pathways would encourage research to bridge gaps in current knowledge. Indeed, deep understanding of lung cell wounding and repair, and discovery of relevant repair moieties for lung cells, should inspire the development of new therapies that are likely preventive and broadly effective for targeting injurious pulmonary diseases.
