Sleep in Patients with Chronic Migraine

Abstract

Purpose of Review

The biological and pathophysiological interaction between sleep and chronic migraine (CM) remains to be fully elucidated. In this article, we provide a narrative review of the literature on sleep disturbance and CM, highlighting recent advances in sleep research and insights into mechanisms that could mediate a role of sleep disturbances in migraine chronification. We discuss the potential for cognitive-behavioral insomnia therapy (CBTi) as an intervention for CM with comorbid insomnia. Finally, we propose a model of the mechanisms underlying the interactions among sleep physiology, maladaptive migraine-coping behaviors, and coexisting factors which contribute to sleep disturbances in CM based on conceptual models used in sleep research.

Recent Findings

Insomnia is the most common sleep complaint among patients with CM. CM patients experience more frequent and severe insomnia symptoms than patients with episodic migraine (EM). It has been suggested that sleep disturbances may predispose individuals to migraine attacks, which may affect the pain-processing trigeminovascular system and thus play a role in migraine progression. Encouraging but limited evidence suggests that management of insomnia via behavioral sleep therapy may reverse CM to EM and possibly prevent migraine chronification.

Summary

Migraine has a complex relationship with sleep. The use of objective sleep study such as polysomnographic microstructural sleep analysis and actigraphy could help connect sleep disturbances and processes related to CM. Future longitudinal studies should examine whether effective behavioral treatments such as CBTi can reverse migraine chronification.

Doing Mastoidectomy Along with Tympanic Membrane Repair Reduces the Need for Revision Procedures: A Prospective Study

Abstract

To determine the role of cortical mastoidectomy on the results of tympanoplsty in tubotympanic type of chronic suppurative otitis media. A prospective, observational, interventional study was conducted from a period of October 2006–October 2008. This included 40 patients of either sex in the age group of 15–45 years having tubotympanic type of CSOM. Tympanoplasty with mastoidectomy was done in all the patients and they were followed up for graft acceptance and hearing impairment for 5 years to see the long term results. Per-operatively, the antrum was involved in 17, aditus in 11 and middle ear in 8 patients. Incus was necrosed in 10 cases and malleus and incus were absent in a single case. Mucoid discharge was found in the middle ear in 12 out of 40 patients. Mucoid discharge ears had antral mucosal hypertrophy in 100%, blocked aditus in 75% and middle ear mucosal hypertrophy in 58% cases; ossicular necrosis in 75% cases. 90% of the cases had graft accepted. In dry ears, graft take up rate was 89% and in ears with mucoid discharge it was 92%. Average air–bone–gap reduced to 13.90 dB as compared to average air–bone–gap (Av. AB Gap1) preoperatively of 38.62 dB. After 5 years, 83.5% patients had >10 dB improvement in hearing. We recommend opening of the mastoid if on inspection of middle ear one finds mucoid type of discharge.

Traditional or regenerative periodontal surgery?—a comparison of the publications between two periodontal journals over time

Abstract

Objectives

The objective is to compare the amount and content of publications regarding traditional or regenerative periodontal surgery in the years 1982/1983 and 2012/2013 in two leading periodontal journals of North America and Europe.

Material and methods

The search was carried out in the Journal of Periodontology and Journal of Clinical Periodontology. Four reviewers screened the articles and allocated the topics with respect to periodontal surgery. The distribution of articles with respect to traditional or regenerative periodontal surgery was then compared between the journals and the respective time periods.

Results

Out of 1084 screened articles, 145 articles were included. Articles with periodontal surgery content amounted to 18% for the first time period and to 11% for the second time period. In the years 1982/1983, 7% of articles in the Journal of Periodontology and 8% in the Journal of Clinical Periodontology referred to traditional periodontal surgery, while 8% (Journal of Periodontology) and 5% (Journal of Clinical Periodontology) examined regenerative periodontal surgery. The distribution changed 30 years later, with 1% (Journal of Periodontology) and 3% (Journal of Clinical Periodontology) traditional periodontal surgery and 7% and 6% regenerative periodontal surgery content.

Conclusion

While the clinical need for traditional periodontal surgery remained, research in this important field decreased. Publications rather tended to focus on adjunctive regenerative measures.

Clinical relevance

Periodontal surgery with adjunctive regenerative measures is an established and well-documented clinical procedure. However, with respect to the dominance of horizontal bone loss in periodontally diseased patients, there is a need for ongoing research with focus on traditional periodontal surgery.

Hard tissue debris removal from the mesial root canal system of mandibular molars with ultrasonically and laser-activated irrigation: a micro-computed tomography study

Abstract

This study is to investigate the efficacy of different irrigant activation techniques on removal of accumulated hard tissue debris (AHTD) in mesial roots of human mandibular molars. Extracted human mandibular molars with an isthmus between the mesial root canals were selected based on micro-CT (μCT) scans. The mesial canals were instrumented to an apical diameter ISO30 using ProTaper rotary files. Teeth were randomly assigned to three irrigant activation groups (n = 10): ultrasonically activated irrigation (UAI) using a size 20 Irrisafe for 3 × 20 s, laser-activated irrigation (LAI) with an Er:YAG laser (2940 nm) and plain 300 μm fiber tip inside the canal (20 mJ, 20 Hz, 3 × 20 s), and laser-activated irrigation with identical parameters with a 400 μm photon-induced photoacoustic streaming (PIPS) tip held at the canal entrance. All teeth were scanned with μCT before and after instrumentation and after irrigant activation. After reconstruction and image processing, the canal system volume filled with hard tissue debris before and after irrigant activation was calculated. Changes in hard tissue debris volumes were compared between groups using one-way ANOVA. The percentage volume of hard tissue debris (vol%) was significantly lower after irrigant activation in all groups. Although the lowest debris values were observed in the laser groups, no significant differences in the vol% of accumulated hard tissue debris after activation were observed between groups. Accumulated hard tissue debris was reduced significantly in all activation groups. Ultrasonically and laser-activated irrigation regimens performed similarly in this respect. None of the tested methods was able to render the root canal systems free of debris.

Endoscopic Treatment of Sphenoid Sinus Mucocele: Case Report and Surgical Considerations

Introduction. The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium. Objective. To report one case of sphenoid sinus mucocele that occurred with headache and was submitted to surgical treatment through endonasal endoscopy approach. Case Report. 59-year-old male patient with history of increasing frontoorbital, bilateral, fluctuating headache and exophthalmos. There was no other associated clinical abnormality. Computed Tomography (CT) and Magnetic Resonance Image (MRI) scans confirmed an expansive mass of sphenoid sinus, suggesting mucocele. The patient was submitted to endonasal endoscopic surgery with posterior ethmoidotomy, large sphenoidotomy, and marsupialization of the lesion. Conclusion. Mucoceles of the sphenoid sinus are a very rare condition with variable clinical and radiological presentation. Surgical treatment is absolutely indicated and early treatment avoids visual damage that can be permanent. Endonasal endoscopic approach with drainage and marsupialization of sphenoid sinus, using a transnasal corridor, is a safe and effective treatment modality.

BackgroundThe effectiveness of the combination chemotherapy of weekly paclitaxel and cetuximab has not yet been compared to that of the current standard regimen, EXTREME (combination of 5-fluorouracil, cisplatin and cetuximab).MethodsWe retrospectively reviewed the clinical records of R/M SCCHN patients who received cetuximab-containing chemotherapy as a first-line therapy; from these, patients receiving a weekly paclitaxel and cetuximab regimen (cohort A) and the EXTREME regimen (cohort B) were extracted. The responses, prognoses and adverse events of these two cohorts were evaluated.ResultsA total of 86 patients were included (cohort A, 49; cohort B, 36). Patients with histories of platinum-based chemotherapy were more frequently given the cohort A treatment. Though the response rates were similar in the two cohorts (45% in cohort A and 51% in cohort B; p=0.83), the progression-free survival (PFS) was significantly more favorable in cohort A by the log-rank test (6.0monthsvs 5.0months; p=0.027). In the Cox-regression hazard analyses, male gender (hazard ratio [HR]=2.1, p=0.010), older age (≥ 70 yo) (HR=5.0, p=0.018), PS 0 (HR=2.2, p=0.027), no history of platinum chemotherapy (HR=3.2, p=0.003) and the presence of a tracheostomy (HR=2.3, p=0.039) were favorable factors within cohort A.ConclusionIn selected R/M SCCHN patients, the combination of weekly paclitaxel and cetuximab could be the better treatment option than the EXTREME regimen.

The Technology of Processed Electroencephalogram Monitoring Devices for Assessment of Depth of Anesthesia.

Commercial brain function monitors for depth of anesthesia have been available for more than 2 decades; there are currently more than 10 devices on the market. Advances in this field are evidenced by updated versions of existing monitors, development of new monitors, and increasing research unveiling the mechanisms of anesthesia on the brain. Electroencephalography signal processing forms an integral part of the technology supporting the brain function monitors for derivation of a depth-of-anesthesia index. This article aims to provide a better understanding of the technology and functionality behind these monitors. This review will highlight the general design principles of these devices and the crucial stages in electroencephalography signal processing and classification, with a focus on the key mathematical techniques used in algorithm development for final derivation of the index representing anesthetic state. We will briefly discuss the advantages and limitations of this technology in the clinical setting as a tool in our repertoire used for optimizing individualized patient care. Also included is a table describing 10 available commercial depth-of-anesthesia monitors. (C) 2017 International Anesthesia Research Society

Reduction in Operating Room Plasma Waste After Evidence-Based Quality Improvement Initiative.

Anesthesiologists request units of plasma in anticipation of transfusion. The amount of plasma transfused intraoperatively is less than that issued (requested, thawed, and sent). We presented institutional-specific data on plasma usage including anesthesiologist-specific ratios of plasma issued-to-transfused. In month-to-month comparisons from the year before the presentation (June-December 2015) to 7 months after (June-December 2016), plasma issued to the operating room was reduced from 434.9 +/- 81 to 327.3 +/- 65 units, a change of 107.6 units per month (95% confidence interval [CI], 22-193); plasma discarded by the blood bank was reduced from 109.7 +/- 48 units to 69.1 +/- 9 units, a change of 40.6 units per month (95% CI, 0.2-81); and plasma transfused went from 188.4 +/- 42 units to 160.7 +/- 52 units, a nonsignificant change of 27.7 units per month (95% CI, -27 to 83).

An Appraisal of the Carlisle-Stouffer-Fisher Method for Assessing Study Data Integrity and Fraud.

Data fabrication and scientific misconduct have been recently uncovered in the anesthesia literature, partly via the work of John Carlisle. In a recent article in Anaesthesia, Carlisle analyzed 5087 randomized clinical trials from anesthesia and general medicine journals from 2000 to 2015. He concluded that in about 6% of studies, data comparing randomized groups on baseline variables, before the given intervention, were either too similar or dissimilar compared to that expected by usual sampling variability under the null hypothesis. Carlisle used the Stouffer-Fisher method of combining P values in Table 1 (the conventional table reporting baseline patient characteristics) for each study, then calculated trial P values and assessed whether they followed a uniform distribution across studies. Extreme P values targeted studies as likely to contain data fabrication or errors. In this Statistical Grand Rounds article, we explain Carlisle's methods, highlight perceived limitations of the proposed approach, and offer recommendations. Our main findings are (1) independence was assumed between variables in a study, which is often false and would lead to "false positive" findings; (2) an "unusual" result from a trial cannot easily be concluded to represent fraud; (3) utilized cutoff values for determining extreme P values were arbitrary; (4) trials were analyzed as if simple randomization was used, introducing bias; (5) not all P values can be accurately generated from summary statistics in a Table 1, sometimes giving incorrect conclusions; (6) small numbers of P values to assess outlier status within studies is not reliable; (7) utilized method to assess deviations from expected distributions may stack the deck; (8) P values across trials assumed to be independent; (9) P value variability not accounted for; and (10) more detailed methods needed to understand exactly what was done. It is not yet known to what extent these concerns affect the accuracy of Carlisle's results. We recommend that Carlisle's methods be improved before widespread use (applying them to every manuscript submitted for publication). Furthermore, lack of data integrity and fraud should ideally be assessed using multiple simultaneous statistical methods to yield more confident results. More sophisticated methods are needed for nonrandomized trials, randomized trial data reported beyond Table 1, and combating growing fraudster sophistication. We encourage all authors to more carefully scrutinize their own reporting. Finally, we believe that reporting of suspected data fraud and integrity issues should be done more discretely and directly by the involved journal to protect honest authors from the stigma of being associated with potential fraud.

Mortality, Geriatric, and Nongeriatric Surgical Risk Factors Among the Eldest Old: A Prospective Observational Study.

BACKGROUND: Preoperative risk and postoperative outcomes among the elderly are the subject of extensive debate. However, the eldest old, that is, the fastest-growing and most vulnerable group, are insufficiently studied; even their mortality rate is unclear. This prospective observational study was performed with the aim of determining the mortality rate of this population and establishing which preoperative conditions were predictors of which postoperative outcomes. The study was undertaken between 2011 and 2015 in a major tertiary care university hospital. METHODS: All patients aged >=85 years undergoing any elective procedure during the study period were included. Patients were followed up for 30 days postoperatively. The preoperative conditions studied were demographic data, grade of surgical complexity (1-3), preoperative comorbidities, and some characteristically geriatric conditions (functional reserve, nutrition, cognitive status, polypharmacy, dependency, and frailty). The outcome measures were 30-day all-cause mortality (primary end point), morbidity, prolonged length of stay, and escalation of care in living conditions. RESULTS: Of 139 eligible patients, 127 completed follow-up. The 30-day mortality was 7.9%; 95% confidence interval (CI), 3.2-12.6. It had 3 predictors: malnutrition (odds ratio [OR], 15; 95% CI, 3-89), complexity 3 (OR, 9.1; CI, 2-52), and osteoporosis/osteoporotic fractures (OR, 14.7; CI, 2-126). Significant predictors for morbidity (40%) were ischemic heart disease (OR, 3.9; CI, 1-11) and complexity 3 (OR, 3.6; CI, 2-9), while a nonfrail phenotype (OR, 0.3; CI, 0.1-0.8) was found to be protective. Only 2 factors were found to be predictive of longer admissions, namely complexity 3 (OR, 4.4; CI, 2-10) and frailty (OR, 2.7; CI, 2-7). Finally, risk factors for escalation of care in living conditions were slow gait (a surrogate for frailty, OR, 2.5; CI, 1-6), complexity 3 (OR, 3.2; CI, 1-7), and hypertension (OR, 2.9; CI, 1-9). CONCLUSIONS: The eldest old is a distinct group with a considerable mortality rate and their own particular risk factors. Surgical complexity and certain geriatric variables (malnutrition and frailty), which are overlooked in American Society of Anesthesiologists and most other usual scores, are particularly relevant in this population. Inclusion of these factors along with appropriate comorbidities for risk stratification should guide better decision making for families and doctors alike and encourage preoperative optimization of patients.

Do advanced glycation end-products cause food allergy?.

Purpose of review: The aim of this study was to appraise the evidence relating to dietary advanced glycation end-products (AGEs), their influence on innate and adaptive immune responses and their possible role in the increasing rate of food allergy that is being observed globally. Recent findings: The western pattern of diet is high in both AGEs and their substrates and this has been increasing in the last 30 years. AGEs mimic alarmins such as S100 proteins and the high molecular group box 1 (HMBG1), binding to the Receptor for Advanced Glycation End Products (RAGE), which in turn influences innate and adaptive immune responses. AGEs can directly cause mast cell activation and degranulation. Population data from USA and Australia have correlates with the rise in food allergy and sources of AGEs in the diet and this is also reinforced by urban and regional data within countries. The function of the RAGE receptor is inter-twined with Toll-like receptor (TLR) signalling and vitamin D levels. Activation of the RAGE receptor results in loss of epithelial integrity. Animal models studies have shown that dietary compounds that reduce the formation of AGEs can protect from the development of food allergies; however, this has not been shown in humans. Summary: Dietary sources of AGEs and their substrates are a plausible contributor to the increasing prevalence of food allergy, which requires prospective evaluation in human populations.

Component resolved diagnostics for hymenoptera venom allergy.

Purpose of review: Component-resolved diagnostics makes use of defined allergen molecules to analyse IgE-mediated sensitizations at a molecular level. Here, we review recent studies on the use of component-resolved diagnostics in the field of Hymenoptera venom allergy (HVA) and discuss its benefits and limitations. Recent findings: Component resolution in HVA has moved from single molecules to panels of allergens. Detection of specific immunoglobulin E (sigE) to marker and cross-reactive venom allergens has been reported to facilitate the discrimination between primary sensitization and cross-reactivity and thus, to provide a better rationale for prescribing venom immunotherapy (VIT), particularly in patients sensitized to both honeybee and vespid venom. Characterization of IgE reactivity to a broad panel of venom allergens has allowed the identification of different sensitization profiles that in honeybee venom allergy were associated with increased risks for side effects or treatment failure of VIT. In contrast, component resolution so far has failed to provide reliable markers for the discrimination of sensitizations to venoms of different members of Vespidae. Summary: Component-resolved diagnostics allows a better understanding of the complexity of sensitization and cross-reactivities in HVA. In addition, the enhanced resolution and precision may allow identification of biomarkers, which can be used for risk stratification in VIT. Knowledge about the molecular composition of different therapeutic preparations may enable the selection of appropriate preparations for VIT according to individual sensitization profiles, an approach consistent with the goals of personalized medicine.

Cadaveric Study of the Articular Branches of the Shoulder Joint.

Background and Objectives: This cadaveric study investigated the anatomic relationships of the articular branches of the suprascapular (SN), axillary (AN), and lateral pectoral nerves (LPN), which are potential targets for shoulder analgesia. Methods: Sixteen embalmed cadavers and 1 unembalmed cadaver, including 33 shoulders total, were dissected. Following dissections, fluoroscopic images were taken to propose an anatomical landmark to be used in shoulder articular branch blockade. Results: Thirty-three shoulders from 17 total cadavers were studied. In a series of 16 shoulders, 16 (100%) of 16 had an intact SN branch innervating the posterior head of the humerus and shoulder capsule. Suprascapular sensory branches coursed laterally from the spinoglenoid notch then toward the glenohumeral joint capsule posteriorly. Axillary nerve articular branches innervated the posterolateral head of the humerus and shoulder capsule in the same 16 (100%) of 16 shoulders. The AN gave branches ascending circumferentially from the quadrangular space to the posterolateral humerus, deep to the deltoid, and inserting at the inferior portion of the posterior joint capsule. In 4 previously dissected and 17 distinct shoulders, intact LPNs could be identified in 14 (67%) of 21 specimens. Of these, 12 (86%) of 14 had articular branches innervating the anterior shoulder joint, and 14 (100%) of 14 LPN articular branches were adjacent to acromial branches of the thoracoacromial blood vessels over the superior aspect of the coracoid process. Conclusions: Articular branches from the SN, AN, and LPN were identified. Articular branches of the SN and AN insert into the capsule overlying the glenohumeral joint posteriorly. Articular branches of the LPN exist and innervate a portion of the anterior shoulder joint. Copyright (C) 2017 by American Society of Regional Anesthesia and Pain Medicine.

Focused Cardiac Ultrasound for the Regional Anesthesiologist and Pain Specialist.

This article in our point-of-care ultrasound (PoCUS) series discusses the benefits of focused cardiac ultrasound (FoCUS) for the regional anesthesiologist and pain specialist. Focused cardiac US is an important tool for all anesthesiologists assessing patients with critical conditions such as shock and cardiac arrest. However, given that ultrasound-guided regional anesthesia is emerging as the new standard of care, there is an expanding role for ultrasound in the perioperative setting for regional anesthesiologists to help improve patient assessment and management. In addition to providing valuable insight into cardiac physiology (preload, afterload, and myocardial contractility), FoCUS can also be used either to assess patients at risk of complications related to regional anesthetic technique or to improve management of patients undergoing regional anesthesia care. Preoperatively, FoCUS can be used to assess patients for significant valvular disease, such as severe aortic stenosis or derangements in volume status before induction of neuraxial anesthesia. Intraoperatively, FoCUS can help differentiate among complications related to regional anesthesia, including high spinal or local anesthetic toxicity resulting in hemodynamic instability or cardiac arrest. Postoperatively, FoCUS can help diagnose and manage common yet life-threatening complications such as pulmonary embolism or derangements in volume status. In this article, we introduce to the regional anesthesiologist interested in learning FoCUS the basic views (subcostal 4-chamber, subcostal inferior vena cava, parasternal short axis, parasternal long axis, and apical 4-chamber), as well as the relevant sonoanatomy. We will also use the I-AIM (Indication, Acquisition, Interpretation, and Medical decision making) framework to describe the clinical circumstances where FoCUS can help identify and manage obvious pathology relevant to the regional anesthesiologist and pain specialist, specifically severe aortic stenosis, hypovolemia, local anesthetic systemic toxicity, and massive pulmonary embolism.
