Episodic Migraine Comorbidities: Avoiding Pitfalls and Taking Therapeutic Opportunities

Abstract

Migraine is a common neurologic disorder. This article will discuss a few factors that influence migraine (mostly episodic) and its treatment, such as sleep, obstructive sleep apnea (OSA), obesity, and affective disorders, as well as autoimmune diseases. Practitioners must be aware of these coexisting conditions (comorbidities) as they affect treatment. It is noted in literature that both the quantity (too much or too few hours) and the quality (OSA related) of sleep may worsen migraine frequency. An associated risk factor for OSA, obesity also increases migraine frequency in episodic migraine cases. A bidirectional relationship with migraine along with depression and anxiety is debated in the literature. Retrospective cohort studies are undecided and lack statistical significance, but prospective studies do show promising results on treatment of anxiety and depression as a means of improving migraine control. Finally, we address the topic of autoimmune diseases and migraine. While few studies exist at this time, there are cohort study groups looking into the association between rheumatoid arthritis, hypothyroidism, and antiphospholipid antibody. There is also evidence for the link between migraine and vascular diseases, including coronary and cerebral diseases. We suggest that these comorbid conditions be taken into account and individualized for each patient along with their pharmaceutical regimen. Physicians should seek a multifactorial treatment plan including diet, exercise, and healthy living to reduce migraine frequency.

The Diagnostic Performance of Ultrasonography and Computed Tomography in Differentiating Superficial from Deep Lobe Parotid Tumors

Abstract

Objectives

To validate and compare ultrasound (US) versus computed tomography (CT) criteria in the localization of superficial/deep lobe tumors of the parotid gland.

Design and Setting

This was a retrospective study of diagnostic tests performed from January 2008 to June 2017.

Participants

We included adult patients who were referred for a neck ultrasonography examination due to parotid tumors, and who subsequently underwent parotid surgery.

Main outcome measures

We assessed the location of parotid tumors, comparing the minimum fascia–tumor distance (MFTD) criterion on an US with eight CT criteria. We analyzed receiver operating characteristic (ROC) curves of the MFTD for malignant, benign, and all parotid tumors, and compared the accuracy, sensitivity, and specificity of the optimal MFTD with those of CT anatomical criteria.

Results

A total of 166 parotid tumors were included. The mean (SD) MFTD in superficial lobe tumors was significantly shorter than that of deep lobe tumors (1.2 [0.7] vs 2.8 [1.9] mm, effect size: 1.84; 95% CI, 1.27 to 2.41). The areas under the ROC curve were 0.63 for malignant tumors and 0.88 for benign tumors. The optimal MFTD cut point was 2.4 mm for the 154 benign parotid tumors and the accuracy, sensitivity, and specificity were 90%, 80% and 91%, respectively. For the 136 benign parotid tumors that underwent CT examination, three criteria had an accuracy of over 90% (FNline, tMasseter and Conn's arc), but the sensitivities were all below 50%.

Conclusions

MFTD is more feasible for benign tumors than for malignant tumors for the localization of parotid tumors. For benign parotid tumors, US is enough to guide operations.

Computerised tomography in the investigation of otalgia of unknown origin; our experience in 100 patients

Abstract

Otalgia is a common presenting symptom in the specialty of ENT. In its primary form it is caused by conditions and diseases affecting the outer, middle or inner ear structures, thus giving rise to pain and discomfort around the ear itself. However, in its secondary form (referred), pain can be remote from the source and thus provide greater diagnostic challenge due to the possibility of occult disease that is not well visualised.

Healthcare utilization and management of actinic keratosis in primary and secondary care: a complementary database analysis

Summary

Background

The high prevalence of actinic keratosis (AK) requires optimal use of healthcare resources.

Objectives

To gain insight in health care utilization and management of AK, by describing the healthcare utilization of people with AK in a population‐based cohort and in a primary and secondary care setting.

Methods

A retrospective cohort study using three complementary data sources was conducted to describe the use of care, diagnosis, treatment, and follow‐up of AK patients in the Netherlands. Data sources consisted of a population‐based cohort study (Rotterdam Study, RS), routine general practitioner (GP) records (Integrated Primary Care Information, IPCI), and nationwide claims data (DBC Information System, DIS).

Results

In the population‐based cohort (RS), 69% (918/1,322) of participants diagnosed with AK during a skin screening visit had no prior AK‐related visit in their GP record. This proportion was 50% for participants with extensive AK (i.e.,≥10 AKs; n=270). Cryotherapy was the most used AK treatment by both GPs (78%) and dermatologists (41‐56%). Topical agents were the second most used treatment by dermatologists (13‐21%) but was rarely applied in primary care (2%). During the first AK related GP visit, 31% (171/554) was referred to a dermatologist, with likelihood of being referred comparable between low and high‐risk patients, which is inconsistent with the guidelines. Annually, 40·000 new claims representing 13% of all dermatology claims were labelled as cutaneous premalignancy. Extensive follow‐up rates (56%) in secondary care were registered, while only 18% received a claim for a subsequent cutaneous malignancy in 5 years.

Conclusions

AK management seems to diverge from guidelines in both primary and secondary care. Underutilization of field treatments, inappropriate treatments and high referral rates without proper risk stratification in primary care, combined with extensive follow‐up in secondary care result in inefficient use of healthcare resources and overburdening in secondary care. Efforts directed to better risk differentiation and guideline adherence may prove useful in increasing the efficiency in AK management.

Prognostic significance and population dynamics of peripheral monocytes in patients with oropharyngeal squamous cell carcinoma

Abstract

Background

Several inflammatory biomarkers are considered potential prognostic factors in various cancers. This study aimed to investigate the prognostic significance and population dynamics of pretreatment inflammatory biomarker levels in patients with oropharyngeal squamous cell carcinoma (OPSCC).

Methods

The influence of neutrophil counts, lymphocyte counts, monocyte counts, platelet counts, lymphocyte‐to‐monocyte ratio (LMR), neutrophil‐to‐lymphocyte ratio, and platelet‐to‐lymphocyte ratio on progression‐free survival (PFS), and overall survival (OS) was analyzed. We also analyzed the peripheral blood mononuclear cells collected from patients and healthy donors (HDs).

Results

Elevated monocyte count was an independent prognostic factor for PFS. Low LMR was an independent prognostic factor for OS. The proportion of intermediate monocytes was lower, and that of classical monocytes was higher in patients than in HDs. Furthermore, PD‐L1 expression on monocytes was higher in patients than in HDs.

Conclusions

We showed the prognostic significance and population dynamics of peripheral monocytes in patients with OPSCC.

Transnasal endoscopic surgery in selected nasal‐ethmoidal cancer with suspected brain invasion: Indications, technique, and outcomes

Abstract

Background

In nasal‐ethmoidal malignancies, brain involvement is associated with dismal prognosis.

Method

Patients undergoing endoscopic resection with transnasal craniectomy and subpial dissection (ERTC‐SD) for brain‐invading nasal‐ethmoidal cancer between 2008 and 2016 were included. Complications were analyzed in all patients, whereas oncological outcomes only in patients with pathological brain invasion. The prognostic impact of previous treatments, brain edema, and histology was assessed. Hospitalization ratio was calculated.

Results

Nineteen patients received ERTC‐SD and 11 had pathological‐proven brain invasion. Histologies were 6 olfactory neuroblastomas (ONB), 3 neuroendocrine carcinomas, and 2 intestinal‐type adenocarcinomas. Mean follow‐up was 21.9 months. Three‐year overall, local recurrence‐free, and distance recurrence‐free survivals were 65.5%, 81.8%, and 68.2%, respectively. Overall and distant recurrence‐free survivals were significantly better in patients with ONB (P = 0.032 and P = 0.013, respectively). Hospitalization ratio was 4.1%. Complication rate was 10.5%.

Conclusion

In selected nasal‐ethmoidal tumors with brain invasion, ERTC‐SD can provide good local control, satisfactory survival, and limited morbidity.

Sequential therapy of neoadjuvant biochemotherapy with cetuximab, paclitaxel, and cisplatin followed by cetuximab‐based concurrent bioradiotherapy in high‐risk locally advanced oral squamous cell carcinoma: Final analysis of a phase 2 clinical trial

Abstract

Background

The prognosis of advanced oral squamous cell carcinoma is poor. We investigated the effect of cetuximab‐based sequential therapy as a primary treatment.

Methods

Forty‐seven treatment‐naive patients with advanced tumors originating from the oral cavity or oropharynx were enrolled. Neoadjuvant cetuximab, paclitaxel, and cisplatin were administered, followed by cetuximab‐based radiotherapy. Immunohistochemical staining was applied to study the tissues.

Results

The best overall response rate was 70.2%, including 4 patients with a complete response and 29 with a partial response. The median progression‐free and overall survival rates were 10.3 and 15.2 months, respectively. Patients with more than 50% tumor reduction with neoadjuvant therapy had better survival outcomes. Twenty‐two patients had severe adverse events with mostly dermatological complications. Of the 16 patients who received operations, 9 had increased PD‐L1 staining compared to pretreatment biopsy in the post hoc study.

Conclusion

The regimen was effective in selected patients. Increased PD‐L1 suggested altered tumor features.

Locoregional failures and their relation to radiation fields following stereotactic body radiotherapy boost for oropharyngeal squamous cell carcinoma

Abstract

Background

To investigate the location of recurrences with respect to the radiation fields in oropharynx cancer after intensity‐modulated radiotherapy and stereotactic body radiotherapy (SBRT) boost.

Methods

Local and regional recurrences were delineated on diagnostic scans which were rigidly coregistered with treatment planning scans, then classified based on the location of the center of mass (COM) as well as volumetrically.

Results

In 195 patients, the 5‐year local and regional control were 90% and 93%, respectively. By COM, 76% of local recurrences were in‐field; 24% were out‐of‐field, significantly higher than 0%‐5% in the literature for conventional regimens (P < 0.01). Regional recurrences (19 in 12 patients) were largely within unirradiated neck levels (47%) and electively irradiated regions (42%).

Conclusions

The regimen with biological equivalent dose intensification provides excellent overall and in‐field local control. The highly conformal boost technique was, however, associated with increased out‐of‐field local failure.

Prognostic factors in patients with soft palate squamous cell carcinoma

Abstract

Background

To define the prognostic factors associated with outcome in patients with soft palate squamous cell carcinoma (SCC).

Methods

Previously untreated patients with soft palate and uvula SCC treated in our institution between 1997 and 2012 were collected. The prognostic value of clinical, hematological, and treatment characteristics was examined.

Results

We identified 156 patients, median age 58 years, with 71% drinkers, 91% smokers; 19% had synchronous cancer. Front‐line treatment was chemoradiotherapy in 58 (37%), radiotherapy alone in 60 (39%), surgery in 17 (11%), and induction chemotherapy in 21 patients (14%). The 5‐year actuarial overall survival (OS) and progression‐free survival (PFS) were 41% and 37%, respectively. In univariate analysis, T3‐T4 vs T1‐T2 stage, N2‐N3 vs N0‐N1 stage, and neutrophil count >7 g/L were associated with worse OS and PFS (P < .05).

Conclusion

In patients with soft palate SCC, inflammation biomarkers were associated with OS.

International validation of the revised European Organisation for Research and Treatment of Cancer Head and Neck Cancer Module, the EORTC QLQ‐HN43: Phase IV

Abstract

Background

We validated the new European Organisation for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ‐HN43).

Methods

We enrolled 812 patients with head and neck cancer from 18 countries. Group 1 completed the questionnaire before therapy, and 3 and 6 months later. In group 2 (survivors), we determined test–retest reliability using intraclass correlation coefficients (ICC). Internal consistency was assessed using Cronbach's Alpha, the scale structure with confirmatory factor analysis, and discriminant validity with known‐group comparisons.

Results

Cronbach's alpha was >0.70 in 10 of the 12 multi‐item scales. All standardized factor loadings exceeded 0.40. The ICC was >0.70 in all but two scales. Differences in scale scores between known‐groups were >10 points in 17 of the 19 scales. Sensitivity to change was found to be sufficient in 18 scales.

Conclusions

Evidence supports the reliability and validity of the EORTC QLQ‐HN43 as a measure of quality of life.

Visceral adipose tissue volume and CT‐attenuation as prognostic factors in patients with head and neck cancer

Abstract

Background

The aim of this study was to evaluate the relationship of the characteristics of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) to the disease progression‐free survival and distant failure‐free survival of head and neck squamous cell carcinoma (HNSCC).

Methods

We enrolled 152 HNSCC patients who underwent staging 18F‐fluorodeoxyglucose (FDG) positron emission tomography/CT (PET/CT). Maximum FDG uptake (standardized uptake value [SUV]) and total lesion glycolysis (TLG) of the primary tumor and volume, CT‐attenuation (Hounsfield units [HU]), and FDG uptake of SAT and VAT were measured. Survival analysis using Cox proportional hazard modeling was performed to assess the relationship between the adipose tissue parameters of PET/CT and survival.

Results

Patients with low VAT volume and high VAT HU had significantly worse progression‐free survival and distant failure‐free survival than those with high VAT volume and low VAT HU. On multivariate analysis, the volume and HU of VAT were significantly correlated with disease progression‐free survival and distant failure‐free survival after adjusting for age, sex, body mass index, TNM stage, serum C‐reactive protein, maximum SUV, and TLG.

Conclusion

The volume and CT‐attenuation of VAT were significantly correlated with disease progression‐free survival and distant failure‐free survival in patients with HNSCC.

Transoral laser microsurgery for glottic cancer in the elderly: Efficacy and safety

Abstract

Background

Data about the results of transoral laser microsurgery (TLM) in elderly patients are limited.

Methods

A retrospective study of 72 consecutive cases of glottic carcinoma (63 pT1 and 9 pT2 cases) in elderly patients (≥70 years old, mean 76 years) treated with TLM was made. A systematic review of the literature was performed.

Results

Six patients (8%) had postoperative complications, but no treatment‐related deaths were observed. Local recurrences occurred in 12 patients (16.5%): nine with pT1 (14%) and three with pT2 (33%) tumors. Five‐year disease‐specific survival (DSS), overall survival, and laryngectomy‐free survival were 95%, 68%, and 88%, respectively. The literature review indicated that TLM is safe and effective treatment for these patients, with few complications and good local control (>85%) and DSS (>90%) rates.

Conclusions

Our results and the information from the literature show that TLM for glottic cancer in elderly patients can lead to satisfactory treatment results.

Value of a smartphone‐compatible thermal imaging camera in the detection of peroneal artery perforators: Comparative study with computed tomography angiography

Abstract

Background

The aim of this study was to investigate the value of a smartphone‐compatible thermal imaging camera in the mapping of the peroneal artery perforators.

Methods

Twelve consecutive patients scheduled for fibular flap reconstruction were enrolled. The lower limbs were first studied using smartphone‐based dynamic infrared thermography (DIRT). During the rewarming, the hotspots were marked, small rubber markers were taped to the registered sites, and then the patients were sent for a CT scan. The diagnostic performance of smartphone‐based DIRT was evaluated by comparing the DIRT findings with CT angiography and intraoperative findings.

Results

DIRT detected 42 of the 57 dominant perforators in 24 limbs and resulted in a sensitivity of 73.7% and a positive predictive value of 65.6%.

Conclusions

The sensitivity and positive predictive value of the smartphone‐based DIRT are low. Currently, it should be used as an adjunctive tool together with the established imaging techniques.

AllergoOncology: microbiota in allergy and cancer ‐ an EAACI position paper

Abstract

The microbiota can play important roles in the development of human immunity and the establishment of immune homeostasis. Lifestyle factors including diet, hygiene, and exposure to viruses or bacteria, and medical interventions with antibiotics or anti‐ulcer medications, regulate phylogenetic variability and the quality of cross‐talk between innate and adaptive immune cells via mucosal and skin epithelia. More recently, microbiota and their composition have been linked to protective effects for health. Imbalance, however, has been linked to immune‐related diseases such as allergy and cancer, characterized by impaired, or exaggerated immune tolerance, respectively. In this AllergoOncology position paper, we focus on the increasing evidence defining the microbiota composition as a key determinant of immunity and immune tolerance, linked to the risk for development of allergic and malignant diseases. We discuss novel insights into the role of microbiota in disease and patient responses to treatments in cancer and in allergy. These may highlight opportunities to improve patient outcomes with medical interventions supported through a restored microbiome.

The functional biology of peanut allergens and possible links to their allergenicity

Abstract

Peanut is one of the most common food triggers of fatal anaphylaxis worldwide although peanut allergy affects only 1‐2% of the general population. Peanuts are the source of highly potent allergenic proteins. It is emerging that the allergenicity of certain proteins is linked to their biological function. Peanut is an unusual crop in that it flowers above ground but produces its seed‐containing pods underground. This so called geocarpic fruiting habit exposes pods and seeds during their development to soilborne pathogens and pests. Pest damage can also open routes of entry for opportunistic fungi such as Aspergillus. Although seed proteins have primary functions in nutrient reservoirs, lipid storage bodies, or the cytoskeleton, they have also evolved to act as part of the plant's defense system to enhance fitness and survival of the species. When interacting with pathogens or pests, these proteins modify and damage cells' membranes, interact with immune receptors and modulate signaling pathways. Moreover, following exposure, the immune system of predisposed individuals reacts to these proteins with the production of specific IgE. This review explores the evolutionary biology of peanut and its seed proteins and highlights possible links between the proteins' biological function and their allergenicity.

Abstract

Systemic lupus erythematosus (SLE) is a connective tissue disease that involves multiple organs. Ocular structures and visual pathways can be affected in SLE because of disease-related eye involvement or drug toxicity. All the part of the eye may be interested with an external, anterior involvement, responsible of the dry eye disease, or posterior (retina) and neuro-ophtalmic manifestations. Retinopathy in SLE is suggestive of high disease activity being a marker of poor visual outcome and prognosis for survival. The early diagnosis is thus the key to a better management and successful treatment. Antimalarial drugs are the cornerstone of SLE treatment and recently the American Academy of Ophthalmology updated the recommendations for hydroxychloroquine retinal toxicity screening which includes the standard automated visual fields and the spectral domain optical coherent tomography. More recently new imaging techniques have been investigated to assess retinal function and reveal subclinical eye involvement. In this review we focalize on the evidence of eye manifestations in SLE, the eye drug toxicity related to antimalarial agents and steroids, and the methods employed for the eye screening. Moreover, the future perspectives on new techniques, such as the optical coherence tomography angiography, are dissected giving new insights on evaluation of microvasculature of the retina and choroid in SLE.

Abstract

The current existing therapies for severe cases of systemic lupus erythematosus (SLE) patients are still limited. Intravenous immunoglobulin (IVIGs), which are purified from the plasma of thousands of healthy human donors, have been profiled as efficacious and life-saving options for SLE patients refractory to conventional therapy. The specific mechanism of action by which IVIGs generate immunomodulation in SLE is not currently understood. In this manuscript, we reviewed some of the hypothesis that have been postulated to explain the IVIG effects, including those on T and B cell intracellular signalling and activation, as well as the interferon signalling pathways involved in the detection of nucleic acids and the defective removal of immune complexes and debris.

The impact of self-replicating proteins on inflammation, autoimmunity and neurodegeneration—An untraveled path

Publication date: Available online 11 January 2019

Source: Autoimmunity Reviews

Author(s): Dana Butnaru, Joab Chapman

Abstract

The central nervous system (CNS) in neurodegenerative diseases is a battlefield in which microglia fight a highly atypical battle. During the inflammatory process microglia themselves become dysfunctional and even with all the available immune arsenal including cytokine or/and antibody production, the battle is eventually lost. A closer look into the picture will reveal the fact that this is mainly due to the atypical characteristics of the infectious agent. The supramolecular assemblies of misfolded proteins carry unique features not encountered in any of the common pathogens. Through misfolding, proteins undergo conformational changes which make them become immunogenic, neurotoxic and highly infective. The immunogenicity appears to be triggered by the exposure of previously hidden hydrophobic portions in proteins which act as damage-associated molecular patters (DAMPs) for the immune system. The neurotoxicity and infectivity are promoted by the small oligomeric forms of misfolded proteins/peptides. Oligomers adopt conformations such as tubular-like, beta-barrel-like, etc., that penetrate cell membranes through their hydrophobic surfaces, thus destabilizing ionic homeostasis. At the same time, oligomers act as a seed for protein misfolding through a prion/prion-like mechanism. Here, we propose the hypothesis that oligomers have catalytic surfaces and exercise their capacity to infect native proteins through specific characteristics such as hydrophobic, electrostatic and π-π stacking interactions as well as the specific surface area (SSA), surface curvature and surface chemistry of their nanoscale supramolecular assemblies. All these are the key elements for prion/prion-like mechanism of self-replication and disease spreading within the CNS. Thus, understanding the mechanism of prion's templating activity may help us in the prevention and development of novel therapeutic strategies for neurodegenerative diseases

Autoantibodies in idiopathic inflammatory myopathies: Clinical associations and laboratory evaluation by mono- and multispecific immunoassays

Abstract

Idiopathic inflammatory myopathies (IIM) are a group of diseases characterized by immune-mediated muscular lesions that may be associated with extra-muscular manifestations involving skin, lungs, heart or joints. Four main groups of IIM can be distinguished: dermatomyositis (DM), overlap myositis including mainly anti-synthetase syndrome (ASS), immune mediated necrotizing myopathy (IMNM), and inclusion body myositis (IBM). Myositis-specific autoantibodies (MSA) are increasingly recognized as valuable tools for diagnosis, classification and prognosis of IIM. For example, ASS is associated with anti-aminoacyl tRNA synthetase antibodies (anti-Jo-1, PL-7, PL-12, …), IMNM with anti-SRP and anti-HMGCR; IBM with anti-cytosolic 5'nucleotidase 1A (cN1A), and DM with anti-Mi-2, anti-MDA-5, anti-TIF-1γ, anti-NXP-2 and anti-SAE. Moreover, anti-MDA-5 is associated with amyopathic myositis and interstitial lung disease and anti-TIF-1γ and anti-NXP-2 with juvenile DM as well as malignancy in patients >40 years. Most MSA have initially been discovered by immunoprecipitation. In routine laboratories, however, MSA are screened for by indirect immunofluorescence and identified by (automated) monospecific immunoassays or by multispecific immunoassays (mainly line/dot immunoassays). Validation of these (multispecific) assays is a challenge as the antibodies are rare and the assays diverse. In this review, we give an overview of the (clinical) performance characteristics of monospecific assays as well as of multispecific assays for detection of MSA. Although most assays are clinically useful, there are differences between techniques and between manufacturers. We discuss that efforts are needed to harmonize and standardize detection of MSA.

Complex regional pain syndrome – False hopes and miscommunications

Publication date: Available online 11 January 2019

Source: Autoimmunity Reviews

Author(s): Christopher Chang, Patrick McDonnell, M. Eric Gershwin

Abstract

Complex regional pain syndrome (CRPS) has been considered to be an autoimmune disease and there have been clinical trials with intravenous immunoglobulin. Often the etiology of the so-called CRPS diagnosis cannot be discerned and there are no validated instruments that provide functional metrics. The term complex regional pain syndrome (CRPS), coined in 1994 to describe patients in whom the pain is out of proportion to the injury, was actually a diagnosis proposed during the American Civil War, but was originally known as causalgia. Physicians have long observed similar sensitivity and inflammatory symptoms following periods of immobilization and disuse, which generally resolve within a few months of remobilization. Following the original description, persistent disproportionate pain would come to be known under many other names until researchers theorized that it was related to dysfunction in the sympathetic nervous system, after which it acquired the moniker, Reflex Sympathetic Dystrophy ("RSD"). In the latter quarter of the twentieth century, after researchers failed to prove the connection between the pain and the sympathetic nervous system, a small cadre of physicians–without rigorous science—invented CRPS. This new descriptor, CRPS, has become not only a diagnosis without objective data but with proposed criteria involving ambiguous signs and symptoms with low specificity. It has led to patients being treated erroneously with sympatholytic drugs, with or without pharmaceutical or surgical blockade of the sympathetic nervous system, unwarranted use of ketamine infusions, inappropriate use of narcotics and nerve stimulation. Intravenous immunoglobulin infusions have not been effective in the treatment of chronic pain. The indiscriminate use of pain medications to treat subjective symptoms of unclear diagnoses can be a risk factor for opioid and analgesic misuse or abuse.

Review: Myositis-specific autoantibodies, a cornerstone in immune-mediated necrotizing myopathy

Publication date: Available online 11 January 2019

Abstract

Over the past few years, myositis-specific autoantibodies played an increasing role in the inflammatory idiopathic myositis definition. They became the critical immunological marker for immune-mediated necrotizing myopathy diagnosis (IMNM) since the paradigm switch from histological to serological criteria.

This review is focused on the key role of the anti-signal recognition particle (anti-SRP) and the anti-3-Hydroxy-3-MethylGlutaryl-Coenzyme A Reductase (anti-HMGCR) antibodies in immune-mediated necrotizing myopathy.

Anti-SRP and anti-HMGCR antibodies are robust diagnostic tools in case of both the classical subacute form and the slowly progressive form of IMNM that may mimic muscular dystrophy. Anti-SRP and anti-HMGCR patients share clinical, biological and histological features with some antibody-associated specificity. Anti-SRP patients harbour more severe muscle weakness and atrophy with severe muscle damage on magnetic resonance imaging study. Approximately 10–20% of anti-SRP patients develop extramuscular symptoms, especially lung interstitial disease. Conversely, anti-HMGCR patients are often associated with statin exposure. In both cases, patients have a poor outcome with frequent relapse and the use of combined immunotherapy. Of note, various data suggest a direct pathogenic role of these antibodies reinforcing the interest in targeted therapeutic strategy.

Autoimmunity in celiac disease: Extra-intestinal manifestations

Publication date: Available online 11 January 2019

Source: Autoimmunity Reviews

Author(s): Lerner Aaron, Matthias Torsten, Wusterhausen Patricia

Abstract

Celiac disease is an autoimmune condition of the small intestine caused by prolamins in genetically susceptible individuals evoked by multiple environmental factors. The pathological luminal intricate eco-events produce multiple signals that irradiate the entire body, resulting in a plethora of extra-intestinal manifestations. Nutrients, dysbiosis, dysbiotic components and their mobilome, post-translational modification of naive proteins, inter-enterocyte's tight junction dysfunction resulting in a leaky gut, microbial lateral genetic transfer of virulent genes, the sensing network of the enteric nervous systems and the ensuing pro-inflammatory messengers are mutually orchestrating the autoimmune interplay. Genetic-environmental-luminal events-mucosal changes are driving centrifugally the remote organs autoimmunity, establishing extra-intestinal multi organ injury. Exploring the underlying intestinal eco-events, the sensing and the delivery pathways and mechanisms that induce the peripheral tissues' damages might unravel new therapeutical strategies to prevent and help the gluten affected patients.

Blockade of YAP alleviates hepatic fibrosis through accelerating apoptosis and reversion of activated hepatic stellate cells

Publication date: March 2019

Source: Molecular Immunology, Volume 107

Author(s): Hai-xia Yu, Yao Yao, Fang-tian Bu, Yu Chen, Yu-ting Wu, Yang Yang, Xin Chen, Yan Zhu, Qin Wang, Xue-yin Pan, Xiao-ming Meng, Cheng Huang, Jun Li

Abstract

Yes-associated protein (YAP) is a significant downstream protein in the Hippo signaling pathway with important functions in cell proliferation, apoptosis, invasion and migration. YAP also plays a role in the progression and development of various liver diseases. In hepatic fibrosis development and reversion, the proliferation and apoptosis of activated hepatic stellate cells (HSCs) play a critical role. However, the contribution of YAP to hepatic fibrosis progression and reversion and the underlying mechanism have not been investigated. Here we investigated the expression and function of YAP in the proliferation and apoptosis of activated HSCs. We found that YAP expression was increased in liver fibrosis tissues from CCl4-induced model mice and restored to normal level after stopping CCl4 injection and 6 weeks of spontaneously recovery. YAP expression was elevated in HSC-T6 cells treated with TGF-β1 and recovered after MDI treatment. Silencing of YAP inhibited the activation and proliferation of HSC-T6 cells stimulated by TGF-β1. In addition, the apoptosis of activated HSC-T6 cells silenced for YAP was slightly enhanced. Furthermore, over-expression of YAP repressed the reversion of activated HSC-T6 cells mediated by MDI reversal. We found that HSC-T6 cells activated by TGF-β1 showed higher levels of nuclear YAP compared with MDI-treated cells, indicating that YAP was activated in HSC-T6 cells treated by TGF-β1. We also found that loss of YAP attenuated Wnt/β-catenin pathway activity in activated HSC-T6 cells. Treatment of VP, an inhibitor of the YAP-TEAD complex, reduced both activation and proliferation of HSC-T6 cells and increased apoptosis. Together these results indicated that reduced expression of YAP contributes to acquisition of the quiescent phenotype in HSCs. Our results suggest that YAP may be a useful target in HSCs activation and reversion.

Abstract
Objectives

In pediatric obstructive sleep apnea (OSA), the relationship between rapid eye movement sleep and upper airway collapse, and between sleep position and airway dimensions are well known. However, the interrelations between these factors and the obstructive apnea hypopnea index (O-AHI) have not been thoroughly investigated.

Methods

A retrospective study including 100 children who underwent adenotonsillectomy between March 2010 and July 2017. Total O-AHI was divided into four subcategories by sleep stage and position.

Results

Preoperatively 14 of 47 mild cases of OSA (1 < total O-AHI) and 17 of 18 moderate (5 < total O-AHI) had time showing severe apnea (10 < subcategorized O-AHI). Twenty-two of 24 severe cases (10 < total O-AHI) exhibited very severe apnea (30 < subcategorized O-AHI). All 11 very severe cases (30 < total O-AHI) experienced more than 50 apnea events per hour in at least one of the O-AHI subcategories. After surgery, 23 of 70 cases classified as completely resolved (total O-AHI < 1) still had mild apnea in the O-AHI subcategories, and six of 13 cases who continued to experience apnea events had moderate-to-severe apnea. Seventeen cases worsened in the O-AHI subcategories, and total O-AHI deteriorated in two cases of the 17. The amount of REM sleep and use of the supine position increased significantly postoperatively in the quartile groups with the lowest baseline values (p < 0.0001).

Conclusions

When an unexpected AHI value is encountered, the O-AHI subcategories may be informative regarding the indications for surgery and evaluating the efficacy thereof.

Author(s): Murray R. Thompson, Catherine S. Birman

Abstract
Objectives

Bilateral duplication of the internal auditory canal (IAC) is rare and is associated with profound sensorineural hearing loss. The present study aims to review our experience with bilateral cochlear implantation (CI) in children with a duplication of the IAC and to review the literature.

Methods

The Sydney Cochlear Implant Centre database was searched for children with duplication of the internal auditory canal. Data was collected regarding clinical history, MRI and CT findings, auditory brainstem responses (ABR), tympanometry and otoacoustic emissions (OAE), visually reinforced orientation audiometry, auditory brainstem response, electrocochleography (ECochG), transtympanic electrical auditory brainstem response (ABR), aided cortical evoked potentials (CAEP) and intraoperative neural response telemetry (NRT) and CI evoked electrical auditory brainstem testing.

Results

two children with bilateral duplication of the IAC were identified who successfully underwent bilateral cochlear implantation. Audiological development was monitored for 2 and 3 years respectively, both children could spontaneously verbalise and displayed Categories of Auditory Performance (CAP) score of 5 and 6 respectively.

Conclusion

Children with duplication of the IAC, with accompanying cochlear nerve dysplasia (CND) can benefit from CI surgery, and verbal receptive and expressive language is possible.

Abstract
Introduction

The endoscopic expanded endonasal approach (EEA) has been shown to be a safe and effective surgical technique in the resection of pediatric skull base lesions. Cerebrospinal fluid (CSF) leaks are among the most common complications of this approach. Here we review skull base resections using EEA in pediatric patients at our single institution, to identify potential risk factors for this surgical complication.

Methods

A retrospective chart review was conducted on pediatric patients at our single institution for patients 19 years-old and under, who underwent an EEA for resection of a skull base tumor.

Results

Thirty-nine pediatric patients (ages 1-19 years) with 8 different tumor pathologies underwent an EEA for resection of their skull base tumors. 21 patients experienced an intraoperative CSF leak, of which 10 (48%) were "high-flow" leaks and 11 (52%) were "low-flow" leaks. Nasoseptal flaps were only used to repair the intraoperative "high flow" leaks (n=10), and "low flow" and "no leaks" were repaired with allograft and fat. No patients experienced a post-operative CSF leak.

Conclusion

In our pediatric series, the skull base repair algorithm of using an NSF only in cases of "high flow" intraoperative leaks was effective, and no post-operative CSF leaks occurred. Not using an NSF in cases of "low-flow" or "no leak" cases allows for decreased anatomical disruption in the growing patient.

RANKL-independent modulation of osteoclastogenesis

Publication date: Available online 11 January 2019

Source: Journal of Oral Biosciences

Author(s): Wei Feng, Jie Guo, Minqi Li

Abstract

Osteoclasts are functional cells required for bone resorption. They are derived from hematopoietic precursors and undergo a series of differentiation and fusion steps in response to various humoral factors. Depending on the importance in osteoclastogenesis, the pathways for the differentiation of hematopoietic precursors to mature osteoclasts can be divided into two categories: canonical and the non-canonical. Receptor activator of nuclear factor κB ligand (RANKL)-induced osteoclast formation is considered as an important canonical pathway. Non-canonical pathways of osteoclastogenesis mainly involve several humoral factors that can substitute for RANKL to induce osteoclast formation. Among these factors, tumor necrosis factor (TNF)-α, interleukin (IL)-1, "homologous to lymphotoxins, exhibiting inducible expression, and competing with herpes simplex virus glycoprotein D for herpesvirus entry mediator, a receptor expressed by T lymphocytes" (LIGHT), a proliferation-inducing ligand (APRIL), and B cell-activating factor (BAFF) belong to the TNF superfamily. Other RANKL substitutes are primarily cytokines and growth factors including transforming growth factor β (TGFβ), IL-6, IL-11, nerve growth factor (NGF), insulin-like growth factor (IGF)-I, and IGF-II. In this review, we summarize the involvement of these factors in inducing osteoclastogenesis in vitro. Although these factors weakly induce osteoclast formation, they may play a major role in pathological bone resorption.

Abstract
OBJECTIVE

The aim of the study was to evaluate gingival manifestation of tuberculosis (TB) in the oral cavity in pediatric patients.

METHOD

Four pediatric patients were enrolled in the study. Clinical symptoms, auxiliary examinations, treatments, and outcomes were recorded and analyzed.

Four pediatric patients who presented with atypical gingival lesions were thoroughly examine for local and systemic signs and symptoms along with detail history. All relevant investigations were performed to arrive a definitive diagnosis of oral tuberculous lesion. Based on final diagnosis, anti-tubercular therapy(ATT) started for all the pediatric patients and outcomes were measured.

RESULTS

All 4 cases responded very well to the treatment with complete resolution of the lesions within 6 months after the initiation of ATT.

CONCLUSION

Healthcare professionals should rule out TB as one of the differential diagnosis in the pediatric patients with atypical gingival lesions. Anti- tubercular therapy is strictly recommended for the treatment of oral tuberculosis to achieve good clinical outcomes. Rapid molecular tests based on nucleic amplification should be recommended for the diagnosis of tuberculosis in children and also for extrapulmonary tuberculosis as it is much faster and reliable than conventional methods.

Author(s): Guilherme C.L.S. do Amaral, Aline C. Planello, Gabriell Borgatto, Dieila Giomo de Lima, Gustavo N. Guimarães, Marcelo Rocha Marques, Ana Paula de Souza

ABSTRACT
Objective

Treatment strategies for Oral Squamous Cell Carcinoma (OSCC) vary based on the stage of diagnosis. Surgery and radiotherapy are options for localized lesions for stage I patients, while chemotherapy is the main treatment for metastatic OSCC. However, aggressive tumors can relapse, causing frequently the death of the patient. In an attempt to address this, novel treatment protocols using epigenetic drugs that alter the epigenetic profile have emerged as an alternative to control tumor growth and metastasis. Therefore, our objective in this study was to investigate the effect of demethylating drug 5-aza-CdR at the concentrations of 0.3 μM and 2 μM in SCC9 cells.

Study Design

SCC9 cells were treated with 5-Aza-CdR at the concentrations of 0.3 μM and 2 μM for 24 h and 48 h. DNA methylation of MGMT, BRCA1, APC, c-MYC and hTERT genes were investigated using Methylation Specific-High Resolution Melting technique. RT-PCR and qPCR were performed to analyze genes expression.

Results

5-Aza-CdR promoted demethylation of MGMT gene and modified the transcription of all analyzed genes. Curiously, 5-aza-CdR at the concentration of 0.3 μM was more efficient than 2 μM in SCC9 cells.

Conclusion

We observed 5-aza-CdR led to MGMT demethylation, upregulated transcription of three important tumor suppressor genes and promoted downregulation of c-Myc.

Acquired medial external auditory canal stenosis, anterior tympanomeatal angle blunting, and lateralized tympanic membrane: Nosology, diagnosis, and treatment

Publication date: Available online 11 January 2019

Abstract
Objectives

To analyze the etiologies, auditory consequences, diagnostic tools and therapeutic results of three often confused pathologies: acquired fibrous stenosis of the medial part of the external auditory canal (EAC), fibrous anterior tympanomeatal angle blunting, and lateralized tympanic membrane.

Material and methods

Retrospective study of 18 cases operated on over a 16-year period (14 patients: 7 female, 7 male; aged 11–64 years): 8 cases of medial EAC stenosis, 3 of blunting, and 7 of tympanic membrane lateralization.

Results

In all 3 pathologies, otoscopic and radiologic diagnosis was easily established, so that they could not be confused. All 3 induced > 33 dB conductive hearing loss. Medial EAC stenosis was secondary to chronic inflammation of the EAC, aggravated by surgery in 5 cases. Blunting was secondary to surgery altering the anterior tympanic annulus. Tympanic membrane lateralization was secondary to prior surgery without inflammatory process. Underlying EAC cholesteatoma was found in 3 cases of medial stenosis and in 1 case of blunting. Surgical results were disappointing in medial stenosis, with 62.5% recurrence and mean functional gain of 9 dB, and in blunting, with 66.7% recurrence and mean functional gain of 6 dB; auditory results were, however, good in these 2 pathologies when there was no recurrence of fibrosis. Results were significantly better in lateralized tympanic membrane, with 28.6% recurrence and mean functional gain of 16 dB.

Conclusion

The good results obtained in tympanic membrane lateralization seem to justify surgery in patients bothered by their hearing loss. The indication is more questionable in cases of medial fibrous stenosis and blunting, although significant auditory improvement is achieved in case of surgical success.

Synergistic effect of hyperbaric oxygen therapy with PTH [1‐34] on calvarial bone graft in irradiated rat

Abstract

Objective

To determine the synergistic effect of parathyroid hormone (PTH) [1‐34] in combination with hyperbaric oxygen (HBO) on bone graft in a rat calvarial bone defect model under impaired osteogenic conditions.

Materials And Methods

Twenty‐four rats were divided into 3 groups. Localized radiation with a single 12 Gy dose was administered to the calvaria. Four weeks after radiation, calvarial circular defects were created in the parietal bones. All defects were filled with biphasic calcium phosphate. After the bone graft, PTH [1‐34] was injected subcutaneously, and HBO was administered. At 6 weeks after the bone graft, the rats were sacrificed, and specimens were harvested.

Results

Histomorphometric evaluation showed that the percentage of new bone area was higher in the PTH and PTH/HBO groups than in the control group. The percent residual material area was decreased in the PTH/HBO group compared with the control group. The percentage blood vessel number was highest in the PTH group. Micro‐CT evaluation showed that the new bone volume was highest in the PTH/HBO group. The residual material volume was lowest in the PTH/HBO group.

Conclusion

Within the limitations of this study, our data indicate that PTH combined with HBO may reverse radiation‐induced impairment of bone healing.

Anesthetic management for medialization laryngoplasty using concurrent infusions of dexmedetomidine, remifentanil, and propofol versus controls

Publication date: Available online 11 January 2019

Source: American Journal of Otolaryngology

Author(s): Kathryn S. Handlogten, Dale C. Ekbom, Megan C. Hamre, Toby N. Weingarten, Darrell R. Schroeder, Troy G. Seelhammer

Abstract
Purpose

Medialization laryngoplasty (ML) ± arytenoid adduction (AA) surgery poses a unique anesthetic challenge that requires periods of deep sedation and patient cooperation with phonation to assess voice function. The purpose of this study was to assess if the protocolized administration of dexmedetomidine, remifentanil, and propofol (DRP) is associated with reduced procedural duration and administration of other sedating medications.

Materials and methods

This was a retrospective 2:1 case matched study design; matched on age, sex, body mass index, AA, and surgical revision status. Data was obtained from the electronic medical record of a tertiary referral center. Cases underwent ML ± AA using DRP. Control subjects underwent surgery ML ± AA without DRP.

Results

58 DRP cases (43.1% AA) were matched with 116 control patients (44.8% AA). DRP was associated with decreases in fentanyl dose (50 [25, 100] vs. 100 [50, 150] mcg; p < 0.01), incidence and dose of midazolam (4 [6.9%] vs. 70 [60.3%]; p < 0.01; 1 [1, 1] vs. 2 [2, 2]; p < 0.02), operative duration (131 ± 33 vs. 160 ± 50 min; p < 0.01), and anesthetic duration (182 ± 35 vs. 219 ± 60.3 min; p < 0.01). When adjusted for timeline, it was observed that case duration was declining prior to DRP introduction; this trend persisted after DRP introduction. Hypopnea was more common with DRP (14 [24.1%] vs. 7 [6.0%]; p < 0.01).

Conclusions

DRP was associated with a substantial decrease in opioid and benzodiazepine administration. A reduction in procedural duration over time was also observed.

C reactive protein (CRP) rs3093059C predicts poor mizolastine response in chronic spontaneous urticaria patients with elevated serum CRP level

Abstract

Chronic spontaneous urticaria (CSU) is a frequent disorder with recurrent itchy wheals and/or angioedema, and nearly 35% patients respond poorly to nonsedating H1 antihistamines treatment. CRP gene encodes the C reactive protein, which is involved in the pathogenesis of CSU. To investigate the impacts of CRP polymorphisms on the susceptibility and therapeutic efficacy in the South Han CSU patients, we enrolled 145 CSU patients in our study. After 4‐week nonsedating H1 antihistamine monotherapy treatment, more than 50% reduction of the severity score is considered as effective, or else non‐effective. The CRP rs3093059T/C and rs2794521G/A genotypes of patients were determined by Sequenom MassARRAY. Functional studies including relative luciferase assay and β‐Hexosaminidase assay were conducted in HEK293T cells or RBL‐2H3 cells to explore the function of variants. Forty (62.50%) CSU patients were effective when treated with mizolastine, and 55(72.4%) patients were effective in the desloratadine group. We found that the patients carried with rs3093059TT genotype was significantly associated with good response (OR=4.20, p=0.015), had lower serum CRP, IL‐6 and TNF‐α levels than the CT/CC genotypes. In vitro, the rs3093059C allele exhibited significantly higher luciferase activity than wild allele (p<0.001). From the β‐Hexosaminidase assay, we observed the inhibiting degranulation effects by mizolastine and this effect is weakened when with a higher dose CRP in RBL‐2H3 cells. Our findings suggested that CSU patients carrying the rs3093059C allele may respond poorly to mizolastine with elevated serum CRP level.

Local hyperthermia cleared multifarious viral warts in a patient with Cushing's syndrome

Abstract

A female Cushing's syndrome patient had been suffering from extensive viral warts for months. She was diagnosed with flat warts, common warts and plantar warts. The plantar warts on her right foot were initially treated using local hyperthermia at 44°C for 30 minutes according to a defined protocol, followed by treatment targeting a common wart on her left thumb. In response to hyperthermia, the flat warts on her eyelid dissipated within 12 weeks, and when combined with a one week administration of imiquimod, the common warts and plantar warts completely disappeared within 8 weeks. There were no signs of recurrence and during this treatment her Cushing's syndrome was alleviated. This pioneer trial suggests that local hyperthermia may serve as an effective mean for treating multiple cutaneous warts under the conditions of a systemic immuno‐compromised disease.

Bupivacaine infiltration in children for postoperative analgesia after tonsillectomy: A randomised controlled study

BACKGROUND Adenotonsillectomy is a frequently performed procedure in paediatric day-case surgery. Postoperative pain can be significant and standard analgesia protocols are often insufficient. OBJECTIVE Our primary objective was to investigate if infiltration of the peritonsillar space with bupivacaine would reduce the need for postoperative opioids compared with pre-emptive intravenous tramadol. DESIGN A prospective, double-blind, randomised controlled trial. SETTING Ambulatory surgical day care centre, University Hospitals of Leuven, Belgium, from January 2012 to September 2016. PATIENTS Two hundred children, between 4 and 10 years old, undergoing elective adenotonsillectomy were included in the study. INTERVENTION Children were randomly allocated to receive either a bolus of 3 mg kg−1 intravenous tramadol or infiltration of the tonsillar lodge with 5-ml bupivacaine 0.25%. Reasons for exclusion were American Society of Anesthesiologists classification greater than 2, allergies to the investigated products, psychomotor retardation, bleeding disorders and lack of proficiency in Flemish. MAIN OUTCOME MEASURES The primary endpoint was the number of children in need of piritramide postoperatively. Secondary outcomes included the cumulative dose of postoperative piritramide, pain scores and the incidence of postoperative nausea and vomiting during the first 24 postoperative hours, time to discharge and adverse effects. RESULTS The proportion of children in need of postoperative piritramide was significantly lower in the tramadol group than in children with peritonsillar infiltration (57 vs. 81%, P

Epidemiology and incidence of severe respiratory critical events in ear, nose and throat surgery in children in Europe: A prospective multicentre observational study

BACKGROUND Ear, nose and throat (ENT) surgery, the most frequently performed surgical procedure in children, is a strong predictor for peri-operative respiratory complications. However, there is no clear information about peri-operative respiratory severe critical events (SCEs) associated with anaesthesia management of ENT children in Europe. OBJECTIVE To characterise the epidemiology and incidence of respiratory SCEs during and following ENT surgery in Europe and to identify the risk factors for their occurrence. DESIGN A secondary analysis of the Anaesthesia PRactice In Children Observational Trial, a prospective observational multicentre cohort trial. SETTING The study included 261 centres across 33 European countries and took place over a consecutive 2-week recruitment period between April 2014 and January 2015. PATIENTS We extracted data from 5592 ENT surgical procedures that were performed on 5572 children aged 6.0 (3.6) years (mean (SD)) from the surgical database and compared these with data from 15 952 non-ENT surgical children aged 6.7 (4.8) years. MAIN OUTCOME MEASURES The primary outcome was the incidence of respiratory SCEs (laryngospasm, bronchospasm and new onset of postoperative stridor). Secondary outcomes were the differences in epidemiology between ENT children and non-ENT surgical children and the risk factors for the occurrence of respiratory SCEs. RESULTS The incidence (95% confidence interval) of any respiratory SCE (laryngospasm, bronchospasm and postoperative stridor) was 3.93% (3.46 to 4.48) and was significantly higher than that observed in non-ENT surgical children [2.61% (2.37 to 2.87)], with a relative risk of 1.51 (1.28 to 1.77), P less than 0.0001. Younger age (14% decrease in critical events by increasing year, P

A comparison of the analgesic efficacy of local infiltration analgesia vs. intrathecal morphine after total knee replacement: A randomised controlled trial

BACKGROUND Local infiltration analgesia (LIA) is an effective pain management technique following total knee arthroplasty (TKA). OBJECTIVE To investigate if LIA provides better analgesia for patients undergoing unilateral TKA than intrathecal morphine. DESIGN Randomised controlled trial. SETTING Single tertiary referral centre. PATIENTS Consecutive American Society of Anesthesiologists Physical Status I to III patients scheduled to undergo unilateral TKA were randomised to two groups. INTERVENTION The control group received spinal anaesthesia with intrathecal bupivacaine and preservative-free morphine 0.3 mg. The intervention group received opioid-free spinal anaesthesia with bupivacaine, followed by intra-operative infiltration of the knee with levobupivacaine 2 mg kg−1 and adrenaline 0.5 mg diluted to a volume of 100 ml with 0.9% saline. An intra-articular catheter was placed during surgery and used to give a bolus of 15 ml of levobupivacaine 0.5% on the morning of the first postoperative day. MAIN OUTCOME MEASURES Visual analogue scale (VAS) scores for pain were assessed repeatedly for 48 h postoperatively, at rest and on passive knee flexion to 30°. The primary outcome was VAS scores for pain at rest and on movement at 24 postoperative hours. Secondary outcomes were VAS scores at rest and on movement at 2, 6, 12 and 48 postoperative hours, opioid consumption, degree of active flexion of operative knee achieved in the first 48 h and the incidence of opioid-related side effects. RESULTS Forty three patients completed the study. Mean (± SD) VAS scores for pain at 24 h were lower in the intervention group than the control group at rest; 16.43 (± 20.3) vs. 37.2 (± 33.6), (P = 0.029). VAS scores for pain at 24 h on movement were also lower in the intervention group vs. the control group; 39.1 (± 22.8) vs. 57.0 (± 30.9), (P = 0.037). VAS scores were also lower on movement; 25.9 (± 16.8) vs. 40.5 (± 24.0), (P = 0.028) at 48 h. CONCLUSION We conclude that LIA conferred superior analgesia compared with intrathecal morphine 0.3 mg at 24 and 48 h following TKA. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT01312415.
