    Asthma is a heterogeneous disease with many phenotypes, and age at disease onset is an important factor in separating the phenotypes. Genetic factors, atopy, and early respiratory tract infections are well-recognized factors predisposing to childhood-onset asthma. Adult-onset asthma is more often associated with obesity, smoking, depression, or other life-style or environmental factors, even though genetic factors and respiratory tract infections may also play a role in adult-onset disease. Adult-onset asthma is characterized by absence of atopy and is often severe requiring treatment with high dose of inhaled and/or oral steroids. Variety of risk factors and nonatopic nature of adult-onset disease suggest that variety of mechanisms is involved in the disease pathogenesis and that these mechanisms differ from the pathobiology of childhood-onset asthma with prevailing Th2 airway inflammation. Recognition of the mechanisms and mediators that drive the adult-onset disease helps to develop novel strategies for the treatment. The aim of this review was to summarize the current knowledge on the pathogenesis of adult-onset asthma and to concentrate on the mechanisms and mediators involved in establishing adult-onset asthma in response to specific risk factors. We also discuss the involvement of these mechanisms in the currently recognized phenotypes of adult-onset asthma. PMID:26538828

    Adult-onset eosinophilic asthma is increasingly recognised as a severe and difficult-to-treat subtype of asthma. In clinical practice, early recognition of patients with this asthma subtype is important because it may have treatment implications. Therefore, physicians need to know the distinct characteristics of this asthma phenotype. The objective of the present study was to determine the characteristic profile of patients with adult-onset eosinophilic asthma. 130 patients with adult-onset (>18 years of age) asthma and high blood eosinophil counts (≥0.3×109 L−1) were compared with 361 adult-onset asthma patients with low (<0.3×109 L−1) blood eosinophils. Measurements included a series of clinical, functional and imaging parameters. Patients with high blood eosinophils were more often male, had less well controlled asthma and higher exacerbation rates, despite the use of higher doses of inhaled corticosteroids. They had higher levels of total IgE without more sensitisation to common inhaled allergens. In addition, these patients had worse lung function, and more often showed fixed airflow limitation, air trapping, nasal polyposis and abnormalities on sinus computed tomography scanning. Chronic rhinosinusitis, air trapping and male sex were three independent factors associated with blood eosinophilia (adjusted OR 3.8 (95% CI 1.7–8.1), 3.0 (95% CI 1.1–8.1) and 2.4 (95% CI 1.3–4.4), respectively). Patients with adult-onset asthma with elevated blood eosinophils exhibit a distinct profile, which can readily be recognised in clinical practice. PMID:27730197

    Objectives Childhood adversities may be important determinants of later illnesses and poor health behaviour. However, large-scale prospective studies on the associations between childhood adversities and the onset of asthma in adulthood are lacking. Design Prospective cohort study with 7-year follow-up. Setting Nationally representative study. Data were collected from the Health and Social Support (HeSSup) survey and national registers. Participants The participants represent the Finnish population from the following age groups: 20–24, 30–34, 40–44, and 50–54 years at baseline in 1998 (24 057 survey participants formed the final cohort of this study). The occurrence of childhood adversities was assessed at baseline with a six-item survey scale. The analyses were adjusted for sociodemographic characteristics, behavioural health risks and common mental disorders. Primary and secondary outcomes The survey data were linked to data from national health registers on incident asthma during a 7-year follow-up to define new-onset asthma cases with verified diagnoses. Results A total of 12 126 (59%) participants reported that they encountered a childhood adversity. Of them 3677 (18% of all) endured three to six adversities. During a follow-up of 7 years, 593 (2.9%) participants were diagnosed with incident asthma. Those who reported three or more childhood adversities had a 1.6-fold (95% CI 1.31 to 2.01) greater risk of asthma compared to those without childhood adversities. This hazard attenuated but remained statistically significant after adjustment for conventional risk factors (HR 1.33; 95% CI 1.06 to 1.67). Conclusions Adults who report having encountered adversities in childhood may have an increased risk of developing asthma. PMID:23069774

    Interleukin 6 (IL6) is an inflammatory cytokine that has been suggested to have an important role in the pathogenesis of asthma. IL6 single-nucleotide polymorphisms (SNPs) have been associated with levels of IL6, and with childhood and prevalent adult asthma. A recent study also suggested that IL6 SNPs associate especially with atopic asthma. However, association of IL6 SNPs with adult-onset asthma has not been studied. In a population-based study of 467 incident adult-onset asthma cases and 613 disease-free controls from South Finland, we analyzed association of 6 tagging SNPs of the IL6 locus with the risk of adult-onset asthma and with atopy. Asthma was clinically diagnosed, and atopy was defined based on Phadiatop test. IL6 SNP rs1800797 associated with the risk of adult-onset asthma in a log additive model, with adjusted odds ratio (aOR) 1.31 (95% confidence interval 1.09-1.57), and especially with the risk of atopic adult-onset asthma when compared with non-atopic controls, aOR 1.46 (95% CI 1.12-1.90). This is the first study to show an association of IL6 with adult-onset asthma, and especially with atopic adult-onset asthma.

    This article describes six patients who presented, usually bilaterally, with yellow-orange, elevated, indurated, and nonulcerated xanthomatous eyelid lesions, typically extending into the anterior orbital fat, and sometimes involving the extraocular muscles and the lacrimal gland. Because the eyelids remained intact and because the process did not reach the deep orbital and perioptic connective tissues, visual acuity was well preserved. There is cosmetic morbidity and occasionally motility restriction with advancing involvement of the extraocular muscles. All patients had variably severe adult-onset asthma that required treatment with systemic prednisone and inhalants. No evidence of Erdheim-Chester disease was found in any patient, but the appearance in one patient, after 25 years of follow-up, of a separate subcutaneous necrobiotic xanthogranulomatous lesion in the mandibular region with an associated paraproteinemia, suggests that at least some of our cases might be a mild form of necrobiotic xanthogranuloma. For this reason, we would suggest repeated periodic serum protein immunoelectrophoretic studies as well as evaluation for lymphoma. Therapy probably should consist of low doses of periorbital radiotherapy coupled with high doses of corticosteroids. Should this not be successful, then systemic administration of corticosteroids with chemotherapeutic agents might be efficacious, as in necrobiotic xanthogranuloma.

    Occupational exposure is a well-recognised modifiable risk factor for asthma, but the relationship between occupational exposure and asthma control has not been studied. We aimed to study this association among working-age adults from the European Community Respiratory Health Survey (ECRHS). Data were available for 7077 participants (mean age 43 years, 45% never-smokers, 5867 without asthma and 1210 with current asthma). Associations between occupational exposure to specific asthmagens and asthma control status (33% with uncontrolled asthma, based on the Global Initiative for Asthma guidelines) were evaluated using logistic and multinomial regressions, adjusted for age, sex and smoking status, with study areas included as a random effect. Statistically significant positive associations were observed between uncontrolled adult-onset asthma and both past 12-month and 10-year exposure to any occupational asthmagens (OR (95% CI) 1.6 (1.0-2.40) and 1.7 (1.2-2.5), respectively); high (1.7 (1.0-2.8) and 1.9 (1.3-2.9), respectively) and low (1.6 (1.0-2.7) and 1.8 (1.2-2.7), respectively) molecular weight agents; and cleaning agents (2.0 (1.1-3.6) and 2.3 (1.4-3.6), respectively), with stronger associations for long-term exposures. These associations were mainly explained by the exacerbation domain of asthma control and no associations were observed between asthmagens and partly controlled asthma. These findings suggest that occupational exposure to asthmagens is associated with uncontrolled adult-onset asthma. Occupational risk factors should be quickly identified to prevent uncontrolled asthma.

    Adult-onset asthma and chronic obstructive pulmonary disease (COPD) are major public health burdens. This review presents a comprehensive synopsis of their epidemiology, pathophysiology, and clinical presentations; describes how they can be distinguished; and considers both established and proposed new approaches to their management. Both adult-onset asthma and COPD are complex diseases arising from gene–environment interactions. Early life exposures such as childhood infections, smoke, obesity, and allergy influence adult-onset asthma. While the established environmental risk factors for COPD are adult tobacco and biomass smoke, there is emerging evidence that some childhood exposures such as maternal smoking and infections may cause COPD. Asthma has been characterized predominantly by Type 2 helper T cell (Th2) cytokine-mediated eosinophilic airway inflammation associated with airway hyperresponsiveness. In established COPD, the inflammatory cell infiltrate in small airways comprises predominantly neutrophils and cytotoxic T cells (CD8 positive lymphocytes). Parenchymal destruction (emphysema) in COPD is associated with loss of lung tissue elasticity, and small airways collapse during exhalation. The precise definition of chronic airflow limitation is affected by age; a fixed cut-off of forced expiratory volume in 1 second/forced vital capacity leads to overdiagnosis of COPD in the elderly. Traditional approaches to distinguishing between asthma and COPD have highlighted age of onset, variability of symptoms, reversibility of airflow limitation, and atopy. Each of these is associated with error due to overlap and convergence of clinical characteristics. The management of chronic stable asthma and COPD is similarly convergent. New approaches to the management of obstructive airway diseases in adults have been proposed based on inflammometry and also multidimensional assessment, which focuses on the four domains of the airways, comorbidity, self-management, and

    Background Genome-wide association studies have identified novel genetic associations for asthma, but without taking into account the role of active tobacco smoking. This study aimed to identify novel genes that interact with ever active tobacco smoking in adult onset asthma. Methods We performed a genome-wide interaction analysis in six studies participating in the GABRIEL consortium following two meta-analyses approaches based on 1) the overall interaction effect and 2) the genetic effect in subjects with and without smoking exposure. We performed a discovery meta-analysis including 4,057 subjects of European descent and replicated our findings in an independent cohort (LifeLines Cohort Study), including 12,475 subjects. Results First approach: 50 SNPs were selected based on an overall interaction effect at p<10−4. The most pronounced interaction effect was observed for rs9969775 on chromosome 9 (discovery meta-analysis: ORint = 0.50, p = 7.63*10−5, replication: ORint = 0.65, p = 0.02). Second approach: 35 SNPs were selected based on the overall genetic effect in exposed subjects (p <10−4). The most pronounced genetic effect was observed for rs5011804 on chromosome 12 (discovery meta-analysis ORint = 1.50, p = 1.21*10−4; replication: ORint = 1.40, p = 0.03). Conclusions Using two genome-wide interaction approaches, we identified novel polymorphisms in non-annotated intergenic regions on chromosomes 9 and 12, that showed suggestive evidence for interaction with active tobacco smoking in the onset of adult asthma.

    The present review addresses recent advances and especially challenging aspects regarding the role of environmental risk factors in adult-onset asthma, for which the causes are poorly established. In the first part of the review, we discuss aspects regarding some environmental risk factors for adult-onset asthma: air pollution, occupational exposures with a focus on an emerging risk represented by exposure to cleaning agents (both at home and in the workplace), and lifestyle and nutrition. The second part is focused on perspectives and challenges, regarding relevant topics on which research is needed to improve the understanding of the role of environmental factors in asthma. Aspects of exposure assessment, the complexity of multiple exposures, the interrelationships of the environment with behavioral characteristics and the importance of studying biological markers and gene-environment interactions to identify the role of the environment in asthma are discussed. We conclude that environmental and lifestyle exposures play an important role in asthma or related phenotypes. The changes in lifestyle and the environment in recent decades have modified the specific risk factors in asthma even for well-recognized risks such as occupational exposures. To better understand the role of the environment in asthma, the use of objective (quantitative measurement of exposures) or modern tools (bar code, GPS) and the development of multidisciplinary collaboration would be very promising. A better understanding of the complex interrelationships between socio-economic, nutritional, lifestyle and environmental conditions might help to study their joint and independent roles in asthma.

    Background: The biological mechanisms by which cleaning products and disinfectants—an emerging risk factor—affect respiratory health remain incompletely evaluated. Studying genes by environment interactions (G × E) may help identify new genes related to adult-onset asthma. Objectives: We identified interactions between genetic polymorphisms of a large set of genes involved in the response to oxidative stress and occupational exposures to low molecular weight (LMW) agents or irritants on adult-onset asthma. Methods: Our data came from three large European cohorts: Epidemiological Family-based Study of the Genetics and Environment of Asthma (EGEA), Swiss Cohort Study on Air Pollution and Lung and Heart Disease in Adults (SAPALDIA), and European Community Respiratory Health Survey in Adults (ECRHS). A candidate pathway–based strategy identified 163 genes involved in the response to oxidative stress and potentially related to exposures to LMW agents/irritants. Occupational exposures were evaluated using an asthma job-exposure matrix and job-specific questionnaires for cleaners and healthcare workers. Logistic regression models were used to detect G × E interactions, adjusted for age, sex, and population ancestry, in 2,599 adults (mean age, 47 years; 60% women, 36% exposed, 18% asthmatics). p-Values were corrected for multiple comparisons. Results: Ever exposure to LMW agents/irritants was associated with current adult-onset asthma [OR = 1.28 (95% CI: 1.04, 1.58)]. Eight single nucleotide polymorphism (SNP) by exposure interactions at five loci were found at p < 0.005: PLA2G4A (rs932476, chromosome 1), near PLA2R1 (rs2667026, chromosome 2), near RELA (rs931127, rs7949980, chromosome 11), PRKD1 (rs1958980, rs11847351, rs1958987, chromosome 14), and PRKCA (rs6504453, chromosome 17). Results were consistent across the three studies and after accounting for smoking. Conclusions: Using a pathway-based selection process, we identified novel genes potentially involved

    Occupational factors contribute to a significant fraction of respiratory disease and symptoms. We evaluated the role of occupational exposures on asthma, chronic bronchitis, and respiratory symptoms in a population-based cohort, the Singapore Chinese Health Study. History of occupations, occupational exposures, and respiratory conditions were collected by interviews with 52,325 Singaporeans born 1918–1953. Exposure to dusts, from cotton, wood, metal, mineral and/or asbestos, was associated with non-chronic cough and/or phlegm (OR = 1.19, 95% CI = 1.08, 1.30), chronic bronchitis (OR = 1.26, 95% CI = 1.01, 1.57) and adult-onset asthma (OR = 1.14, 95% CI = 1.00, 1.30). Cotton dust was the major component contributing to respiratory symptoms. Vapor exposure, from chemical solvents, dyes, cooling oils, paints, wood preservatives and/or pesticides, was associated with non-chronic cough or phlegm (OR = 1.14, 95% CI = 1.03, 1.27), chronic dry cough (OR = 1.55, 95% CI = 1.19, 2.01) and adult-onset asthma (OR = 1.34, 95% CI = 1.15, 1.56). Chemical solvents, cooling oils and pesticides were the major sources contributing to respiratory symptoms. These data support the role of occupational exposures in the etiology of respiratory illness in a population-based cohort in Singapore with a low prevalence of atopic illness. PMID:16707657

    Asthma is a heterogeneous airway disease with various clinical phenotypes. It is crucial to clearly identify clinical phenotypes to achieve better asthma management. We used cluster analysis to classify the clinical groups of 724 asthmatic patients from the Cohort for Reality and Evolution of Adult Asthma in Korea (COREA), and in 1843 subjects from another independent Korean asthma cohort of Soonchunhyang University Asthma Genome Research Centre (SCH) (Bucheon, Republic of Korea). Hierarchical cluster analysis was performed by Ward's method, followed by κ-means cluster analysis. Cluster analysis of the COREA cohort indicated four asthma subtypes: 1) smoking asthma; 2) severe obstructive asthma; 3) early-onset atopic asthma; and 4) late-onset mild asthma. An independent cluster analysis of the SCH cohort also indicated four clusters that were similar to the COREA clusters. Our results indicate that adult Korean asthma patients can be classified into four distinct clusters.

    Adult onset asthma and periocular xanthogranuloma (AAPOX) is a rare non-Langerhans histiocytosis characterized histopathologically by a periocular infiltration of foamy histiocytes and Touton giant cells. Benign hyperplasia with plasma cell infiltration is classically described in eyelids or lymph nodes of AAPOX patients. It is also a characteristic feature of IgG4-related disease (IgG4-RD), a new entity defined by an IgG4-bearing plasma cell infiltration of organs.To determine if AAPOX syndrome shares clinical, biological, and histopathological characteristics with IgG4-RD, we used the comprehensive clinical diagnostic criteria for IgG4-RD in a retrospective case series of three consecutive patients with histologically-proven AAPOX. Patients who were diagnosed with AAPOX at a French academic referral center for orbital inflammation between November 1996 and March 2013 were enrolled. Biopsies from ocular adnexa or other organs were systematically reexamined. For each patient, clinical and serological data, radiologic findings, and treatment were retrospectively analyzed.Two AAPOX patients fulfilled all of the diagnostic criteria for a definite IgG4-RD. One patient who lacked the serological criteria fulfilled the criteria of a probable IgG4-RD.These 3 cases of AAPOX patients fulfilled the IgG4-RD comprehensive clinical diagnostic criteria. To our knowledge, this is the first observational case report study to clearly show a strong relationship between IgG4-RD and AAPOX syndrome.

    Patch formulation of tulobuterol has been used in asthma treatment as a long-acting β2 -agonist (LABA) through sustained skin absorption. Its treatment efficacy, especially in small airways, remains poorly understood. The study aim was to investigate LABA add-on effects of tulobuterol patch (TP) and salmeterol inhaler (SA) on pulmonary function, asthma control and health status. Patients who had adult-onset under-control asthma, despite taking inhaled corticosteroids, were enrolled in a randomized, open-label, parallel-group, proof-of-concept study of 12-week add-on treatment with TP (n=16) or SA (n=17). Spirometry, impulse oscillometry (IOS), exhaled nitric oxide levels, and clinical questionnaires of asthma control, health status (St. George's Respiratory Questionnaire: SGRQ), and symptoms were evaluated every 4 weeks. Add-on treatment of SA significantly improved the spirometric indices of small airway obstruction (forced expiratory flow between 25% and 75% of FVC: FEF25-75 , and maximum expiratory flow at 25% of FVC: MEF25 ) and IOS indices of whole respiratory resistance (resistance at 5 Hz) as compared to TP. In intra-group comparisons, add-on treatment of TP improved the scores of the asthma control test and the total SGRQ, as well as the symptom and impact components of the SGRQ. SA add-on treatment improved FEV1 and IOS parameters of resistance at 20 Hz and reactance at 5 Hz. Neither of the treatments improved exhaled nitric oxide levels. In conclusion, add-on treatment of TP improved asthma control and health status, whereas SA improved pulmonary function measures associated with large and small airway involvement among patients with adult-onset mild-to-moderate asthma.

    Retinoblastoma (RB) is the most common primary malignant intraocular tumor of childhood presenting usually before 5 years of age. RB in adults older than 20 years is extremely rare. A literature search using PubMed/PubMed Central, Scopus, Google Scholar, EMBASE, and Cochrane databases revealed only 45 cases till date. Over the past decade, there has been a significant increase in the number of such reports, indicating heightened level of suspicion among ophthalmologists. Compared to its pediatric counterpart, adult onset RB poses unique challenges in diagnosis and treatment. This article summarizes available literature on adult onset RB and its clinical and pathologic profile, genetics, association with retinocytoma, diagnostics, treatment, and outcomes. PMID:27609158

    Asthma is a heterogeneous disease with many phenotypes, and age at disease onset is an important factor in separating the phenotypes. Most studies with asthma have been performed in patients being otherwise healthy. However, in real life, comorbid diseases are very common in adult patients. We review here the emerging comorbid conditions to asthma such as obesity, metabolic syndrome, diabetes mellitus type 2 (DM2), and cardiac and psychiatric diseases. Their role as risk factors for incident asthma and whether they affect clinical asthma are evaluated. Obesity, independently or as a part of metabolic syndrome, DM2, and depression are risk factors for incident asthma. In contrast, the effects of comorbidities on clinical asthma are less well-known and mostly studies are lacking. Cross-sectional studies in obese asthmatics suggest that they may have less well controlled asthma and worse lung function. However, no long-term clinical follow-up studies with these comorbidities and asthma were identified. These emerging comorbidities often occur in the same multimorbid adult patient and may have in common metabolic pathways and inflammatory or other alterations such as early life exposures, systemic inflammation, inflammasome, adipokines, hyperglycemia, hyperinsulinemia, lung mechanics, mitochondrial dysfunction, disturbed nitric oxide metabolism, and leukotrienes.

Patients with obesity-related asthma tend to have worse asthma control and quality of life disproportionate to their pulmonary function tests, are less responsive to corticosteroid therapy, and are more likely to have obesity-related comorbidities such as obstructive sleep apnea and gastroesophageal disease that complicate asthma treatment. With the increasing prevalence of obesity, the prevalence of asthma is anticipated to grow proportionally. Addressing weight loss and encouraging activity is essential in the management of obesity-related asthma. This article briefly overviews the epidemiology, unique distinguishing features, potential mechanisms, and approach to management of patients with obesity-related asthma in adults.

    Adverse childhood experiences such as abuse and neglect are associated with subsequent immune dysregulation. Some studies show an association between adverse childhood experiences and asthma onset, although significant disparity in results exists in the published literature. We aimed to review available studies employing a prospective design that investigates associations between adverse childhood experience and asthma. A search protocol was developed and studies were drawn from four electronic journal databases. Studies were selected in accordance with pre-set inclusion criteria and relevant data were extracted. 12 studies, assessing data from a total of 31 524 individuals, were identified that investigate the impact of a range of adverse childhood experiences on the likelihood of developing asthma. Evidence suggests that chronic stress exposure and maternal distress in pregnancy operate synergistically with known triggers such as traffic-related air pollution to increase asthma risk. Chronic stress in early life is associated with an increased risk of asthma onset. There is evidence that adverse childhood experience increases the impact of traffic-related air pollution and inconsistent evidence that adverse childhood experience has an independent effect on asthma onset.

    The prevalence of food allergy is increasing in both the pediatric and adult populations. While symptom onset occurs mostly during childhood, there are a considerable number of patients whose symptoms first begin to appear after the age of 18 years. The majority of patients with adult-onset food allergy suffer from the pollen-plant allergy syndromes. Many of them manifest their allergy after exercise and consuming food to which they are allergic. Eosinophilic esophagitis, an eosinophilic inflammation of the esophagus affecting individuals of all ages, recently emerged as another allergic manifestation, with both immediate and late response to the ingested food. This review provides a condensed update of the current data in the literature on adult-onset allergy.

  4. Practical management of acute asthma in adults.

    All asthma patients are at risk for acute asthma exacerbations. Moderate to severe exacerbations account for many emergency department visits and subsequent hospitalizations each year. Recent studies have advanced our understanding of the pathogenesis and treatment of acute asthma. The purpose of this review is to provide practical guidance in the assessment and treatment of adults with acute asthma in the hospital setting. Managing patients with acute asthma involves assessing the severity of the exacerbation, implementing measures to rapidly reverse airflow limitation, and instituting therapies that limit the progression of airway inflammation. Some patients may benefit from other supportive measures such as heliox and noninvasive ventilation. If the patient continues to deteriorate and requires mechanical ventilation, then ventilator settings that minimize the risk of hyperinflation should be chosen. After an episode of acute asthma, long-term preventive medications, especially inhaled corticosteroids, should be prescribed and education should be provided to prevent future episodes.

    Adult bronchial asthma is characterized by chronic airway inflammation, and presents clinically with variable airway narrowing (wheezes and dyspnea) and cough. Long-standing asthma induces airway remodeling, leading to intractable asthma. The number of patients with asthma has increased; however, the number of patients who die of asthma has decreased (1.2 per 100,000 patients in 2015). The goal of asthma treatment is to enable patients with asthma to attain normal pulmonary function and lead a normal life, without any symptoms. A good relationship between physicians and patients is indispensable for appropriate treatment. Long-term management by therapeutic agents and elimination of the causes and risk factors of asthma are fundamental to its treatment. Four steps in pharmacotherapy differentiate between mild and intensive treatments; each step includes an appropriate daily dose of an inhaled corticosteroid, varying from low to high levels. Long-acting β2-agonists, leukotriene receptor antagonists, sustained-release theophylline, and long-acting muscarinic antagonist are recommended as add-on drugs, while anti-immunoglobulin E antibody and oral steroids are considered for the most severe and persistent asthma related to allergic reactions. Bronchial thermoplasty has recently been developed for severe, persistent asthma, but its long-term efficacy is not known. Inhaled β2-agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, and other approaches are used as needed during acute exacerbations, by choosing treatment steps for asthma in accordance with the severity of exacerbations. Allergic rhinitis, eosinophilic chronic rhinosinusitis, eosinophilic otitis, chronic obstructive pulmonary disease, aspirin-induced asthma, and pregnancy are also important issues that need to be considered in asthma therapy.

    As a chronic disease with intermittent exacerbations, asthma is treated primarily in the outpatient setting by primary care physicians. Asthma is the result of complex and only partially understood interactions of respiratory, inflammatory, and neural cells and their mediators. The goals of asthma therapy are to prevent and relieve symptoms, allow normal activities of daily living, restore and maintain normal pulmonary function, avoid adverse effects from interventions, and minimize inconvenience and cost. These goals can be achieved through educating patients, assessing and monitoring asthma severity, avoiding or controlling asthma triggers, establishing an intervention plan for routine self-management and the management of exacerbations, and providing regular follow-up care. We present a stepped approach to asthma pharmacotherapy, emphasizing anti-inflammatory therapy--inhaled corticosteroids, cromolyn sodium, or nedocromil sodium--as a summary of recent national and international recommendations.

    Mitochondrial diseases are polymorphic entities which may affect many organs and systems. Skeletal muscle involvement is frequent in the context of systemic mitochondrial disease, but adult-onset pure mitochondrial myopathy appears to be rare. We report 3 patients with progressive skeletal mitochondrial myopathy starting in adult age. In all cases, the proximal myopathy was the only clinical feature. Mitochondrial pathology was confirmed by evidence of ragged-red fibres in muscle histochemistry, an abnormal mitochondrial morphology in electron microscopy and by exclusion of other underlying diseases. No deletions of mitochondrial DNA were found. We emphasize the need to look for a mitochondrial disorder in some non-specific myopathies starting in adult life. Images Figure 1 Figure 2 PMID:1589382

    Objectives There is evidence that exposure to air pollution affects asthma, but the effect of air pollution on asthma severity has not been addressed. The aim was to assess the relation between asthma severity during the past 12 months and home outdoor concentrations of air pollution. Methods Asthma severity over the last 12 months was assessed in two complementary ways among 328 adult asthmatics from the French Epidemiological study on the Genetics and Environment of Asthma (EGEA) examined between 1991 and 1995. The 4-class severity score integrated clinical events and type of treatment. The 5-level asthma score is based only on the occurrence of symptoms. Nitrogen dioxide (NO2), sulphur dioxide (SO2) and ozone (O3) concentrations were assigned to each residence using two different methods. The first was based on the closest monitor data from 1991–1995. The second consisted in spatial models that used geostatistical interpolations and then assigned air pollutants to the geo-coded residences (1998). Results Higher asthma severity score was significantly related to the 8-hour average of ozone during April-September (O3-8hr) and the number of days (O3-days) with 8-hour ozone averages above 110 μg.m−3 (for a 36-day increase, equivalent to the inter quartile range, in O3-days, odds ratio (95% confidence interval) 2.22 (1.61–3.07) for one class difference in score). Adjustment for age, sex, smoking habits, occupational exposure, and educational level did not alter results. Asthma severity was unrelated to NO2. Both exposure assessment methods and severity scores resulted in very similar findings. SO2 correlated with severity but reached statistical significance only for the model based assignment of exposure. Conclusions The observed associations between asthma severity and air pollution, in particular O3, support the hypothesis that air pollution at levels far below current standards increases asthma severity.

    The association of asthma with occupational exposures was studied in 14,151 adults, aged 25-59 years, from the general population of the 1975 French Pollution Atmospherique et Affections Respiratoires Chroniques (PAARC) Survey. Associations of asthma with specific jobs, such as personal care workers, waiters, and stock clerks, were observed, with age-, sex-, and smoking-adjusted odds ratios between 1.5 and 1.7. Exposures to 18 asthmagenic agents (low and high molecular weight and mixed environment) were estimated by an asthma-specific job exposure matrix. Risks associated with asthma increased when subjects with imprecise estimates of exposure were excluded. Risks increased further with increasing specificity of the definition of asthma when considering jobs or specific agents, such as industrial cleaning agents, latex, flour, highly reactive chemicals, and textiles. For example, for industrial cleaning agents, odds ratios increased from 1.55 (95% confidence interval (CI): 1.08, 2.23) for "ever asthma," to 2.17 (95% CI: 1.41, 3.34) for asthma onset after age 14 years, to 2.35 (95% CI: 1.38, 4.00) for asthma onset after beginning current job, and to 2.51 (95% CI: 1.33, 4.75) for asthma with airflow limitation. Results underlined the importance of the specificity of exposure and asthma definitions and indicated a deleterious role of occupational exposure on asthma, especially for cleaning agents.

    Objectives: In a large population-based study among adults in northern Europe the relation between occupational exposure and new-onset asthma was studied. Methods: The study comprised 13 284 subjects born between 1945 and 1973, who answered a questionnaire 1989–1992 and again 1999–2001. Asthma was defined as ‘Asthma diagnosed by a physician’ with reported year of diagnose. Hazard ratios (HR), for new-onset adult asthma during 1980–2000, were calculated using a modified job-exposure matrix as well as high-risk occupations in Cox regression models. The analyses were made separately for men and women and were also stratified for atopy. Results: During the observation period there were 429 subjects with new-onset asthma with an asthma incidence of 1.3 cases per 1000 person-years for men and 2.4 for women. A significant increase in new-onset asthma was seen for men exposed to plant-associated antigens (HR = 3.6; 95% CI [confidence interval] = 1.4–9.0), epoxy (HR = 2.4; 95% CI = 1.3–4.5), diisocyanates (HR = 2.1; 95% CI = 1.2–3.7) and accidental peak exposures to irritants (HR = 2.4; 95% CI = 1.3–4.7). Both men and women exposed to cleaning agents had an increased asthma risk. When stratifying for atopy an increased asthma risk were seen in non-atopic men exposed to acrylates (HR = 3.3; 95% CI = 1.4–7.5), epoxy compounds (HR = 3.6; 95% CI = 1.6–7.9), diisocyanates and accidental peak exposures to irritants (HR = 3.0; 95% CI = 1.2–7.2). Population attributable risk for occupational asthma was 14% for men and 7% for women. Conclusions: This population-based study showed that men exposed to epoxy, diisocyanates and acrylates had an increased risk of new-onset asthma. Non-atopics seemed to be at higher risk than atopics, except for exposure to high molecular weight agents. Increased asthma risks among cleaners, spray painters, plumbers, and hairdressers were confirmed. PMID:23204511

    Asthma is a chronic inflammatory disorder that is characterized by 3 distinct responses in the airways: inflammation, hyperresponsiveness, and remodeling. Clinical diagnosis of asthma is often based on the presence of symptoms, such as cough, wheeze, breathlessness, and chest tightness; but the presence of these symptoms is not exclusive to asthma, and clinical correlation with spirometry and other diagnostic testing is essential. Once a diagnosis of asthma is established, the focus of care should be toward control of the disease. This article discusses the pathophysiology, diagnosis, and clinical assessment of asthma in the adult patient population.

    The authors conducted a prospective study of a cohort of 3091 nonsmokers, ages 27 to 87 years, to evaluate the association between long-term ambient ozone exposure and development of adult-onset asthma. Over a 15-year period, 3.2% of males and 4.3% of females reported new doctor diagnoses of asthma. For males, they observed a significant relationship between report of doctor diagnosis of asthma and 20-year mean 8-h average ambient ozone concentration. The authors observed no such relationship for females. Other variables significantly related to development of asthma were a history of ever-smoking for males, and for females, number of years worked with a smoker, age, and a history of childhood pneumonia or bronchitis. Addition of other pollutants to the models did not diminish the relationship between ozone and asthma for males. These data suggest that long-term exposure to ambient ozone is associated with development of asthma in adult males.

    The present paper is focusing on rare diseases manifesting in late childhood or adulthood. A part of these syndromes are not of genetic origin, such as relatively or absolutely rare infections, autoimmune diseases, tumours, or diseases due to rare environmental toxic agents. In addition, even a large proportion of genetic disorders may develop in adulthood or may have adult forms as well, affecting are almost each medical specialization. Examples are storage disorders (e.g. adult form of Tay-Sachs disease, Gaucher-disease), enzyme deficiencies (e.g. ornithin-transcarbamylase deficiency of the urea cycle disorders), rare thrombophilias (e.g. homozygous factor V. Leiden mutation, antithrombin deficiency), or some rare monogenic disorders such as Huntington-chorea and many others. It is now generally accepted that at least half of the 6-8000 "rare diseases" belong either to the scope of adult-care (e.g. internal medicine, neurology), or to "age-neutral" specialities such as ophtalmology, dermatology etc.).

    Several studies have shown gender differences in prevalence of asthma but there is little information about asthma control. In this study, we aimed to evaluate the effect of gender on asthma control in adult asthmatics. Medical records of 242 patients older than 18 years of age who regularly visited the allergy unit were evaluated. Standardized asthma questionnaires like the asthma control test (ACT) were performed. ACT scores, clinical characteristics, and demographic data such as smoking status, education, duration and severity of asthma, atopic status, family history of asthma, analgesic hypersensitivity, number of emergency visits, and hospitalization in the previous year were compared based on gender. In this study, 77.3% of the patients were female. Mean age, body mass index, and duration of asthma were 39.0 ± 0.7, 27.3 ± 0.3, and 6.6 ± 0.4 years, respectively. Of the total, 14.9% of the patients were smokers. Also, 55.8% of them were graduated from middle school, 22.7% from high school, and 14% from university. Atopy rate was 57%. Analgesic hypersensitivity was found in 18.6% of them. There was 30.2% family history of asthma. The asthma severity was mild in 45.5%, moderate in 40.9%, and severe in 13.6% of the patients. One-third of the patients were admitted to emergency room; 1/10th were hospitalized due to asthma in the previous year. ACT scores indicated complete control in 67.8%, partial control in 17.8%, and uncontrolled asthma in 14.5%. Comparing the results of males with females having asthma, there was no statistically significant difference between the two gender according to ACT scores and clinical characteristics. Finally, the results conclude that there was no effect of gender on asthma control assessed with standardized questionnaire in adult asthmatics.

    Since June 4, 2004, asthma diagnosed and symptomatic after the age of 12 years has been an exclusion criterion for military enlistment unless exempted via medical waiver. The Department of Defense determined that 13% of U.S. Army Medic visits in Iraq are for new-onset acute respiratory illness; case reports of veterans with asthma that began in Iraq and Afghanistan War zones have surfaced. This prompted our study to determine whether new asthma is diagnosed more frequently among Iraq/Afghanistan War troops versus stateside-based troops. Retrospective review of asthma diagnoses among computerized charts for military personnel discharged from active duty and examined between March 1, 2004 and May 1, 2007, at the Veterans Affairs Medical Center (VAMC), Northport, NY, classified soldiers by (1) deployment status-whether they were stationed in Iraq/Afghanistan for a 1-year tour of duty or stationed in the United States, and (2) VA diagnosis of asthma per International Classification of Disease codes. Associations between deployment and asthma statuses were evaluated/stratified by gender/age group. Eligibility criteria entailed (1) residence in Long Island, (2) aged 18-45 years, and (3) both U.S. military service and discharge dates between March 1, 2004 and May 1, 2007. Out of 6233 patients who served between 2004 and 2007 and were followed at the Northport VAMC, 290 new-onset/prevalent asthma cases were identified. Deployment to Iraq was associated with a significantly higher risk of asthma compared with stateside soldiers (6.6% versus 4.3%; with a crude odds ratio, 1.58; 95% CI, 1.18, 2.11). These associations persist when stratified by gender and age group. Deployment to Iraq and Afghanistan is associated with new-onset asthma. Etiologic studies, surveillance, incidence, epidemiology, and assessing response to therapy are recommended.

    In this review, our aim was to examine the influence of geographic variations on asthma prevalence and morbidity among adults, which is important for improving our understanding, identifying the burden, and for developing and implementing interventions aimed at reducing asthma morbidity. Asthma is a complex inflammatory disease of multifactorial origin, and is influenced by both environmental and genetic factors. The disparities in asthma prevalence and morbidity among the world's geographic locations are more likely to be associated with environmental exposures than genetic differences. In writing this article, we found that the indoor factors most consistently associated with asthma and asthma-related symptoms in adults included fuel combustion, mold growth, and environmental tobacco smoke in both urban and rural areas. Asthma and asthma-related symptoms occurred more frequently in urban than in rural areas, and that difference correlated with environmental risk exposures, SES, and healthcare access. Environmental risk factors to which urban adults were more frequently exposed than rural adults were dust mites,high levels of vehicle emissions, and a westernized lifestyle.Exposure to indoor biological contaminants in the urban environment is common.The main risk factors for developing asthma in urban areas are atopy and allergy to house dust mites, followed by allergens from animal dander. House dust mite exposure may potentially explain differences in diagnosis of asthma prevalence and morbidity among adults in urban vs. rural areas. In addition, the prevalence of asthma morbidity increases with urbanization. High levels of vehicle emissions,Western lifestyles and degree of urbanization itself, may affect outdoor and thereby indoor air quality. In urban areas, biomass fuels have been widely replaced by cleaner energy sources at home, such as gas and electricity, but in most developing countries, coal is still a major source of fuel for cooking and heating

    Background The evaluation of asthma symptoms is a core outcome measure in asthma clinical research. The Asthma Symptom Utility Index (ASUI) was developed to assess frequency and severity of asthma symptoms. The psychometric properties of the ASUI are not well characterized and a minimal important difference (MID) is not established. Objectives We assessed the reliability, validity, and responsiveness to change of the ASUI in a population of adult asthma patients. We also sought to determine the MID for the ASUI. Methods Adult asthma patients (n = 1648) from two previously completed multicenter randomized trials were included. Demographic information, spirometry, ASUI scores, and other asthma questionnaire scores were obtained at baseline and during follow-up visits. Participants also kept a daily asthma diary. Results Internal consistency reliability of the ASUI was 0.74 (Cronbach’s alpha). Test-retest reliability was 0.76 (intra-class correlation). Construct validity was demonstrated by significant correlations between ASUI scores and Asthma Control Questionnaire (ACQ) scores (Spearman correlation r = −0.79, 95% CI [−0.85, −0.75], P<0.001) and Mini Asthma Quality of Life Questionnaire (Mini AQLQ) scores (r = 0.59, 95% CI [0.51, 0.61], P<0.001). Responsiveness to change was demonstrated, with significant differences between mean changes in ASUI score across groups of participants differing by 10% in the percent predicted FEV1 (P<0.001), and by 0.5 points in ACQ score (P < 0.001). Anchor-based methods and statistical methods support an MID for the ASUI of 0.09 points. Conclusions The ASUI is reliable, valid, and responsive to changes in asthma control over time. The MID of the ASUI (range of scores 0–1) is 0.09. PMID:23026499

    Asthma is a common long-term condition that remains poorly controlled in many people despite the availability of pharmacological interventions, evidence-based treatment guidelines and care pathways.(1) There is considerable public interest in the use of non-pharmacological approaches for the treatment of asthma.(2) A survey of people with asthma reported that many have used complementary and alternative medicine, often without the knowledge of their clinical team.(3) Such interventions include breathing techniques, herbal products, homeopathy and acupuncture. The role of breathing exercises within the management of asthma has been controversial, partly because early claims of effectiveness were exaggerated.(4) UK national guidance and international guidelines on the management of asthma have included the option of breathing exercise programmes as an adjuvant to pharmacological treatment.(5,6) Here we discuss the types of breathing exercises used and review the evidence for their effectiveness.

    BACKGROUND Little is known about adult-onset opsoclonus-myoclonus syndrome (OMS) outside of individual case reports. OBJECTIVE To describe adult-onset OMS. DESIGN Review of medical records (January 1, 1990, through December 31, 2011), prospective telephone surveillance, and literature review (January 1, 1967, through December 31, 2011). SETTING Department of Neurology, Mayo Clinic, Rochester, Minnesota. PATIENTS Twenty-one Mayo Clinic patients and 116 previously reported patients with adult-onset OMS. MAIN OUTCOME MEASURES Clinical course and longitudinal outcomes. RESULTS The median age at onset of the 21 OMS patients at the Mayo Clinic was 47 years (range, 27-78 years); 11 were women. Symptoms reported at the first visit included dizziness, 14 patients; balance difficulties, 14; nausea and/or vomiting, 10; vision abnormalities, 6; tremor/tremulousness, 4; and altered speech, 2. Myoclonus distribution was extremities, 15 patients; craniocervical, 8; and trunk, 4. Cancer was detected in 3 patients (breast adenocarcinoma, 2; and small cell lung carcinoma, 1); a parainfectious cause was assumed in the remainder of the patients. Follow-up of 1 month or more was available for 19 patients (median, 43 months; range, 1-187 months). Treatment (median, 6 weeks) consisted of immunotherapy and symptomatic therapy in 16 patients, immunotherapy alone for 2, and clonazepam alone for 1. Of these 19 patients, OMS remitted in 13 and improved in 3; 3 patients died (neurologic decline, 1; cancer, 1; and myocardial infarction, 1). The cause of death was of paraneoplastic origin in 60 of 116 literature review patients, with the most common carcinomas being lung (33 patients) and breast (7); the most common antibody was antineuronal nuclear antibody type 2 (anti-Ri, 15). Other causes were idiopathic in origin, 38 patients; parainfectious, 15 (human immunodeficiency virus, 7); toxic/metabolic, 2; and other autoimmune, 1.

    Background: Asthma is a chronic disease which places considerable economic, social and public health burdens on the society. Education, occupation and income are the most widely used indicators of socioeconomic status (SES). Studies have shown increased asthma hospital admissions for those who are materially deprived and increased asthma severity in low social class groups. The aim of this study is to determine the impact of socioeconomic status on control of asthma in adults. Method: The study was a cross-sectional analytical one, conducted over a year at the Medical Outpatient Clinic of the University College Hospital Ibadan. The study population was composed of 355 randomly selected adults aged between 18years and 55years with an established diagnosis of asthma already on treatment. Results: Respondents with monthly income of 40000 and above had a higher proportion with good asthma control (74.1%) compared to those that earned 10000 to 39999 (69.0%) and less than 10000 (47.8%). This was statistically significant. Respondents in occupational class I/II had a slightly higher proportion with good asthma control (70.9%) compared to those in occupation class III/IV (70.1%) and occupation class V/VI (50.6%). This was statistically significant at p = 0.003. Conclusion: Respondents in the higher occupational class had better asthma control than respondents in the lower occupational class. Respondents who were earning 40000 and above as monthly income had better control of asthma than other respondents. After adjusting for other variables, the predictor of good asthma control was monthly income of the respondents. PMID:28337093

    The objective of the study was to compare the prevalence of self-reported physician-diagnosed asthma and age at asthma onset between Swedish adolescent elite skiers and a reference group and to assess risk factors associated with asthma. Postal questionnaires were sent to 253 pupils at the Swedish National Elite Sport Schools for cross-country skiing, biathlon, and ski-orienteering ("skiers") and a random sample of 500 adolescents aged 16-20, matched for sport school municipalities ("reference"). The response rate was 96% among the skiers and 48% in the reference group. The proportion of participants with self-reported physician-diagnosed asthma was higher among skiers than in the reference group (27 vs. 19%, p = 0.046). Female skiers reported a higher prevalence of physician-diagnosed asthma compared to male skiers (34 vs. 20%, p = 0.021). The median age at asthma onset was higher among skiers (12.0 vs. 8.0 years; p < 0.001). Female sex, family history of asthma, nasal allergy, and being a skier were risk factors associated with self-reported physician-diagnosed asthma. Swedish adolescent elite cross-country skiers have a higher asthma prevalence and later age at asthma onset compared to a reference population. Being an adolescent elite skier is an independent risk factor associated with asthma. This article is protected by copyright. All rights reserved.

    Occupational asthma is important both as a potentially curable and preventable cause of asthma and as a model of adult onset asthma. It is induced by sensitization to a specific agent inhaled at work; for many of its causes, including inhaled proteins and the low molecular weight chemicals acid anhydrides and reactive dyes, it is probably IgE dependent. The risk of developing specific IgE and associated asthma is markedly increased in cigarette smokers, probably as a consequence of non-specific damage to the respiratory mucosa. Asthma caused by several agents, which include some of its most frequent causes, isocyanates, colophony and plicatic acid (Western Red Cedar) persists in some 50% of cases for years, and possibly indefinitely, after avoidance of exposure. The development of chronic symptomatic asthma seems particularly to occur in those with longer duration of symptomatic exposure. PMID:3074282

    Childhood obesity is a risk factor for asthma, but the molecular mechanisms linking both remain elusive. Since obesity leads to chronic low-grade inflammation and affects metabolic signaling we hypothesized that postnatal hyperalimentation (pHA) induced by maternal high-fat-diet during lactation leads to early-onset obesity and dysregulates pulmonary adipocytokine/insulin signaling, resulting in metabolic programming of asthma-like disease in adult mice. Offspring with pHA showed at postnatal day 21 (P21): (1) early-onset obesity, greater fat-mass, increased expression of IL-1β, IL-23, and Tnf-α, greater serum leptin and reduced glucose tolerance than Control (Ctrl); (2) less STAT3/AMPKα-activation, greater SOCS3 expression and reduced AKT/GSK3β-activation in the lung, indicative of leptin resistance and insulin signaling, respectively; (3) increased lung mRNA of IL-6, IL-13, IL-17A and Tnf-α. At P70 body weight, fat-mass, and cytokine mRNA expression were similar in the pHA and Ctrl, but serum leptin and IL-6 were greater, and insulin signaling and glucose tolerance impaired. Peribronchial elastic fiber content, bronchial smooth muscle layer, and deposition of connective tissue were not different after pHA. Despite unaltered bronchial structure mice after pHA exhibited significantly increased airway reactivity. Our study does not only demonstrate that early-onset obesity transiently activates pulmonary adipocytokine/insulin signaling and induces airway hyperreactivity in mice, but also provides new insights into metabolic programming of childhood obesity-related asthma.

    Background The relationship between obesity and asthma is an area of debate. Objective To investigate the association of elevated body mass index (BMI) at a young age and young adult asthma. Methods BMI, questionnaires, and serologic tests results were analyzed in participants of a predominantly white, middle-class, population-based birth cohort from Detroit, Michigan at 6 to 8 and 18 years of age. Asthma diagnosis was based on medical record data. Allergen specific IgE was analyzed using UniCAP, with atopy defined as 1 or more allergen specific IgE levels of 0.35 kU/L or higher. Overweight was defined as a BMI in 85th percentile or higher. Results A total of 10.6% of overweight males at 6 to 8 years of age had current asthma at 18 to 20 years of age compared with 3.2% of males who were normal or underweight (relative risk [RR], 3.3; 95% confidence interval [CI], 1.0–11.0; P=.048). A total of 19.6% of females who were overweight at 6 to 8 years of age had asthma compared with 10.3% of females who were normal or underweight (RR, 1.9; 95% CI, 0.9–3.9; P=.09). After adjustment for atopy at 6 to 8 years of age, overweight males had an adjusted RR of 4.7 (95% CI, 1.4–16.2; P=.01), and overweight females had an adjusted RR of 1.7 (95% CI, 0.8–3.3; P=.15). Change in BMI between 6 to 8 years of age and 18 to 20 years of age was also examined. Patients with persistently elevated BMI exhibited increased risk of asthma as young adults (RR, 2.4; 95% CI, 1.2–4.7) but not with an increasing BMI (RR, 0.8; 95% CI, 0.3–2.2) or a decreasing BMI (RR, 0.8; 95% CI, 0.3–2.2). Conclusion Overweight males 6 to 8 years of age have increased risk of asthma as young adults. Being overweight remains a predictor of asthma after adjustment for early atopy. A similar but not statistically significant trend was also seen among overweight females. Overweight body habitus throughout childhood is a risk factor for young adult asthma. PMID:23176878

    2016-12-01

    Asthma is a chronic inflammatory airway disease, and its treatment is frequently challenging despite detailed national and international guidelines. While basic anti-inflammatory therapy usually consists of inhaled corticosteroids in doses adapted to the asthma severity, add-on treatment with bronchodilators is essential in more severe asthma. Only recently, the long-acting anticholinergic tiotropium was introduced into the GINA guidelines. This review reports on the studies that have been performed with tiotropium in adult asthmatic patients. Following early proof-of-concept studies, several studies with tiotropium as an add-on therapy to inhaled corticosteroids (ICS), with or without a long-acting beta agonist (LABA), demonstrated convincing clinical benefit for patients. Important lung function parameters and quality of life scores significantly improved shortly after onset of the add-on therapy with tiotropium, and some studies even demonstrated non-inferiority against salmeterol. All studies reported an excellent safety profile of tiotropium. The still growing body of tiotropium studies, both in adults and children, will help to identify the position of tiotropium in future asthma guidelines and might also indicate which patients benefit most from an add-on therapy with tiotropium.

    Purpose We present the case of an 18-year-old Caucasian male with a unilateral macular star and retinal vascular anomalies compatible with adult onset Coats’ disease. Methods Diagnosis was based on fundoscopic, fluorescein angiography and optical coherence tomography findings. Results The patient presented to our emergency department with complaints of low vision in his left eye (LE) detected 10 days before. The best-corrected visual acuity in the LE was 20/50. Fundoscopy of the LE evidenced a complete macular star. Optical coherence tomography showed increased retinal thickness, infiltration of the retinal wall, and detachment of the neuroepithelium. Angiography revealed no appreciable diffusion in the macula. Above the superior temporal (ST) arcade, anomalies in the retinal vasculature were found, with interruption of the peripheral vessels and vessels which were ‘sausage’-like. After 1 month, the LE vision evolved to hand movements. Laser photocoagulation was performed in the ST quadrant. Intravitreal injection of bevacizumab 1.25 mg/0.05 ml and photodynamic therapy were performed without any significant changes, progression of ST serous detachment of the neuroepithelium, and finally progression to macular fibrosis. Discussion Coats’ disease is usually diagnosed in childhood, but rare cases may occur in adults. Those cases usually have a more indolent course which was not observed in our patient. When there is macular involvement, prognosis is more guarded, despite treatment. PMID:22548045

  10. Update on differences between childhood-onset and adult-onset systemic lupus erythematosus

    PubMed Central

    2013-01-01

    Systemic lupus erythematosus (SLE) is a complex autoimmune disease and occurs worldwide in both children and adults. The estimated annual incidence among children is 2.22/100,000 and among adults is 23.2/100,000 in the United States. There is increasing understanding about differences in disease manifestations, medication use, and disease severity between those with childhood-onset SLE as compared with adult-onset SLE. Children have a more fulminant disease onset and course than adults with SLE, resulting in two to three times higher mortality. In future years, we anticipate more insight into the genetics between childhood-onset SLE and adult-onset SLE to help delineate the best therapies for both subsets of patients. PMID:23998441

    Asthma and atopic disorders are the most common chronic diseases in the developed countries. Knowledge of the risk factors for these disorders may facilitate the development of preventive strategies aimed at reducing prevalence rates. To investigate the risk factors for asthma and allergic diseases in a large number of adults who are the parents of children in the National Asthma Campaign Manchester Asthma and Allergy Study. All pregnant women and their partners attending "Booking" antenatal clinics were invited to take part in the study. Questionnaire data were collected including the history of asthma and other atopic diseases, pet ownership and smoking habits, and skin prick tests were performed. The prevalence of atopy and the risk factors for asthma and allergic disorders were investigated in all subjects who completed the questionnaire and underwent skin testing. Statistical analysis was carried out using logistic regression. Initially, risk factors were assessed by univariate analysis to see how each potential explanatory variable affected the probability of having allergic disease. Variables were then tested in a forward stepwise multivariate analysis. In 5687 adult subjects there was a very high (48.2%) prevalence of atopy, and 9.7% of subjects had a diagnosis of asthma. In a multivariate regression analysis sensitization to dust mite, cat, dog and mixed grasses were all independently associated with asthma. The odds ratios for current asthma increased with the increasing number of positive skin tests (any two allergens - OR 4.3, 95% CI 3.3-5.5; any three allergens - OR 7.0 95% CI 5.3-9.3; all four allergens - OR 10.4, 95% CI 7.7-14; P < 0.00001). Dog ownership (OR 1.31, 95% CI 1.10-1.57; P = 0.003) and current smoking (OR 1.36, 95% CI 1.15-1.62; P = 0.0004) were significantly and directly associated with "asthma ever". Thirteen per cent of participants reported a history of eczema. In the multivariate analysis the strongest independent associate of eczema

    Background The question of whether air pollution contributes to asthma onset remains unresolved. Objectives In this study, we assessed the association between asthma onset in children and traffic-related air pollution. Methods We selected a sample of 217 children from participants in the Southern California Children’s Health Study, a prospective cohort designed to investigate associations between air pollution and respiratory health in children 10–18 years of age. Individual covariates and new asthma incidence (30 cases) were reported annually through questionnaires during 8 years of follow-up. Children had nitrogen dioxide monitors placed outside their home for 2 weeks in the summer and 2 weeks in the fall–winter season as a marker of traffic-related air pollution. We used multilevel Cox models to test the associations between asthma and air pollution. Results In models controlling for confounders, incident asthma was positively associated with traffic pollution, with a hazard ratio (HR) of 1.29 [95% confidence interval (CI), 1.07–1.56] across the average within-community interquartile range of 6.2 ppb in annual residential NO2. Using the total interquartile range for all measurements of 28.9 ppb increased the HR to 3.25 (95% CI, 1.35–7.85). Conclusions In this cohort, markers of traffic-related air pollution were associated with the onset of asthma. The risks observed suggest that air pollution exposure contributes to new-onset asthma.

    Many toxic compounds found in air emissions may induce bronchoconstriction. In the workplace, workers are exposed to these compounds, often in much higher concentrations. Some of these compounds act as sensitizers. Of these, some compounds induce asthma by producing specific IgE antibodies to the compound or its protein conjugate, while others induce asthma through yet unidentified immunologic mechanisms. Some compounds, when inhaled in high concentrations, act as irritants and produce bronchoconstriction probably by inducing acute airway inflammation. The latter condition is called Reactive Airways Dysfunction Syndrome (RADS) or irritant-induced asthma. Occupational asthma is an excellent model to study the pathogenesis and the natural history of adult onset asthma because the responsible agent can be identified, complete avoidance is possible, and exposure can be measured or estimated.

  16. Dysfunctional breathing phenotype in adults with asthma - incidence and risk factors

    PubMed Central

    2012-01-01

    Background Abnormal breathing patterns may cause characteristic symptoms and impair quality of life. In a cross-sectional survey 29% of adults treated for asthma in primary care had symptoms suggestive of dysfunctional breathing (DB), more likely to be female and younger, with no differences for severity of asthma. No clear risk factors were demonstrated for DB in asthma, nor the impact of asthma medication was evaluated. The objective of this study was to describe the DB phenotype in adults with asthma treated in a specialised asthma centre. Methods Adult patients aged 17–65 with diagnosed asthma were screened for DB using the Nijmegen questionnaire (positive predictive score >23) and confirmed by progressive exercise testing. The following were evaluated as independent risk factors for DB in the multiple regression analysis: female sex; atopy, obesity, active smoker, moderate/severe rhinitis, psychopathology, GERD, arterial hypertension; severe asthma, asthma duration > 5 years, lack of asthma control, fixed airway obstruction, fast lung function decline, frequent exacerbator and brittle asthma phenotypes; lack of ICS, use of LABA or LTRA. Results 91 adults with asthma, mean age 35.04 ±1.19 years, 47(51.65%) females were evaluated. 27 (29.67%) subjects had a positive screening score on Nijmegen questionnaire and 16(17.58%) were confirmed by progressive exercise testing as having DB. Independent risk factors for DB were psychopathology (p = 0.000002), frequent exacerbator asthma phenotype (p = 0.01) and uncontrolled asthma (p < 0.000001). Conclusion Dysfunctional breathing is not infrequent in asthma patients and should be evaluated in asthma patients presenting with psychopathology, frequent severe asthma exacerbations or uncontrolled asthma. Asthma medication (ICS, LABA or LTRA) had no significant relation with dysfunctional breathing. PMID:22992302

    There are many reasons why online self-management education is attractive to both patients and providers. AsthmaWise, an online self-management program, was developed using a Moodle platform, to enable older adults to learn asthma self-management skills. This study aimed to improve AsthmaWise through conducting: usability testing with a sample of end users; a cognitive walk-through undertaken by an independent health researcher; and assessment of content readability. A Perceived Health Web Site Usability Questionnaire score of 67% was achieved, indicating that there were usability issues that needed to be addressed. The cognitive walk-through and readability assessment identified unique issues that were not identified through usability testing with end users. The testing process allowed issues to be identified and rectified before piloting AsthmaWise, creating a more accessible and refined end product. The involvement of the site designer in the testing process was valuable and is highly recommended. This study shows that usability testing involving both end users and experts is an essential part of the design process that is relatively easy and inexpensive to undertake and can be effectively conducted by a nonexpert.

    Summary Background Asthma is one of the chronic inflammatory diseases. It is known that chronic inflammation accelerates atherosclerosis. Abdominal aortic stiffness parameters can be used to detect the early development of atherosclerosis. Aim In this study, we aimed to evaluate abdominal aortic stiffness parameters in childhood-onset asthma compared with a control group. Methods In this cross-sectional, case–control study, we evaluated 50 patients with childhood-onset asthma, and 57 healthy children as controls. Patients with a diagnosis of asthma of at least three years’ duration were included in the study. Children with hypertension, hyperlipidaemia, diabetes, a history of smoking contact, or systemic disease were excluded. The study and control groups were evaluated with transthoracic echocardiography, and abdominal aorta diameters were measured. Using the measured data, abdominal aortic stiffness parameters (aortic distensibility: DIS, aortic strain: S, pressure strain elastic modulus: Ep, and pressure strain normalised by diastolic pressure: Ep*) were calculated. Statistical evaluation was done with the Student’s t-test, chisquared test and Pearson’s correlation test. Results The study group consisted of 50 children (24 female, 26 male) with asthma. According to the GINA guidelines, 26 of the patients had mild intermittant asthma, six had mild persistent asthma and 18 had intermediate persistent asthma. None of the patients had severe asthma. In 37 of the asthma patients, spIgE was positive and these patients were accepted as having atopic asthma; 27 of these patients received immunotherapy. We did not detect any differences between the study and control groups in terms of gender, age and body mass index. No differences were evident between the groups with regard to systolic and diastolic blood pressure, heart rate, blood cholesterol levels and respiratory function test parameters. There was no difference between the asthma and control groups in the

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

    Workers in various industries and occupations are at risk for work-related asthma* (1). Data from the 2006-2007 adult Behavioral Risk Factor Surveillance System (BRFSS) Asthma Call-back Survey (ACBS), an in-depth asthma survey conducted with respondents who report an asthma diagnosis, from 33 states indicated that up to 48% of adult current asthma might be related to work and could therefore potentially be prevented (2). Identification of the industries and occupations with increased prevalence of asthma might inform work-related asthma intervention and prevention efforts. To assess the industry-specific and occupation-specific proportions of adults with current asthma by state, CDC analyzed data from the 2013 BRFSS industry and occupation module, collected from 21 states for participants aged ≥18 years who, at the time of the survey interview, were employed or had been out of work for <12 months. Among these respondents, 7.7% had current asthma; based on the Asthma Call-back Survey results, this finding means as many as 2.7 million U.S. workers might have asthma caused by or exacerbated by workplace conditions. State-specific variations in the prevalence of current asthma by industry and occupation were observed. By state, current asthma prevalence was highest among workers in the information industry (18.0%) in Massachusetts and in health care support occupations (21.5%) in Michigan. Analysis of BRFSS industry and occupation and optional asthma modules can be used to identify industries and occupations to assess for asthma among workers, identify workplace exposures, and guide the design and evaluation of effective work-related asthma prevention and education programs (1).

    We report the case of a 23-year-old man diagnosed with adult-onset idiopathic chondrolysis of the hip. Chondrolysis of the hip is a disorder most frequently seen in children who have suffered with slipped capital femoral epiphyses. Idiopathic chondrolysis of the hip is extremely rare and to our knowledge, its onset has never been documented in adults aged over 20. With reference to the available medical literature, we summarise the current clinical management of this unusual but important cause of young adult hip pain.

    Background: Inhaled corticosteroids (ICS) affect many inflammatory pathways in asthma but have little impact on cysteinyl leukotrienes. This may partly explain persistent airway inflammation during chronic ICS treatment and failure to achieve adequate asthma control in some patients. This double blind, randomised, parallel group, non-inferiority, multicentre 16 week study compared the clinical benefits of adding montelukast to budesonide with doubling the budesonide dose in adults with asthma. Methods: After a 1 month single blind run in period, patients inadequately controlled on inhaled budesonide (800 µg/day) were randomised to receive montelukast 10 mg + inhaled budesonide 800 µg/day (n=448) or budesonide 1600 µg/day (n=441) for 12 weeks. Results: Both groups showed progressive improvement in several measures of asthma control compared with baseline. Mean morning peak expiratory flow (AM PEF) improved similarly in the last 10 weeks of treatment compared with baseline in both the montelukast + budesonide group and in the double dose budesonide group (33.5 v 30.1 l/min). During days 1–3 after start of treatment, the change in AM PEF from baseline was significantly greater in the montelukast + budesonide group than in the double dose budesonide group (20.1 v 9.6 l/min, p<0.001), indicating faster onset of action in the montelukast group. Both groups showed similar improvements with respect to "as needed" ß agonist use, mean daytime symptom score, nocturnal awakenings, exacerbations, asthma free days, peripheral eosinophil counts, and asthma specific quality of life. Both montelukast + budesonide and double dose budesonide were generally well tolerated. Conclusion: The addition of montelukast to inhaled budesonide is an effective and well tolerated alternative to doubling the dose of inhaled budesonide in adult asthma patients experiencing symptoms and inadequate control on budesonide alone.

    Adult Still's Disease was first described in 1971 by Bywaters in fourteen adult female patients who presented with symptoms indistinguishable from that of classic childhood Still's Disease (Bywaters, 1971). George Still in 1896 first recognized this triad of quotidian (daily) fevers, evanescent rash, and arthritis in children with what later became known as juvenile inflammatory arthritis (Still, 1990). Adult Onset Still's Disease (AOSD) is an inflammatory condition of unknown etiology characterized by an evanescent rash, quotidian fevers, and arthralgias. Numerous infectious agents have been associated with its presentation. This case is to our knowledge the first presentation of AOSD in the setting of Rocky Mountain Spotted Fever. Although numerous infectious agents have been suggested, the etiology of this disorder remains elusive. Nevertheless, infection may in fact play a role in triggering the onset of symptoms in those with this disorder. Our case presentation is, to our knowledge, the first case of Adult Onset Still's Disease associated with Rocky Mountain spotted fever (RMSF).

    Objectives Sugar-sweetened beverage (SSB) intake among U.S. adults is associated with obesity and type 2 diabetes. An association between SSB intake and asthma has been shown among U.S. children and Australian adults, but scant published information exists for U.S. adults. We examined associations between SSB intake and current asthma among U.S. adults, and the role of obesity in this association. Methods We analyzed 2013 Behavioral Risk Factor Surveillance System data for 146,990 adults (≥18 years) from 23 states and the District of Columbia. We used multivariable logistic regression to estimate associations between current asthma and frequency (none, <1 time/day, once/day, ≥2 times/day) of SSB intake (soda, fruit drink, sweet tea, and sports/energy drink). SSB intake was measured using two questions. Covariates included age, sex, race/ethnicity, education, and smoking. Obesity, based on self-reported height and weight, was assessed as an effect modifier. Results Overall, 9.1% of adults reported current asthma: 8.5% of adults who did not consume SSBs had current asthma vs 12.1% of adults who consumed SSBs ≥2 times/day. There was no difference in asthma prevalence with SSB intake <1 time/day (8.7%) or once/day (8.7%). Among non-obese adults, the odds of having current asthma were higher among those who consumed SSBs ≥2 times/day (aOR=1.66, 95%CI=1.39, 1.99) than non-SSB consumers. However, SSB intake frequency was not associated with asthma among obese adults. Conclusions Frequent SSB consumption was associated with asthma among non-obese adults. Research on asthma prevention should further consider the potential adverse effects of high SSB intake among U.S. adults. PMID:27496394

    A 62-year-old man was hospitalized for acute rheumatic fever. He had previously suffered from rheumatic fever at 15 years of age. The rheumatic fever was complicated by carditis, which caused valve disease that required surgical treatment. The incidence of rheumatic fever has decreased in most developed countries with improvements in sanitary conditions. The low incidence of this disease makes a timely and accurate diagnosis difficult. Due to the fact that both the first occurrence and recurrence of acute rheumatic fever can occur in the elderly and adults, this potential disease should not be overlooked when making a differential diagnosis.

    A series of 262 patients with amenorrhea of adult onset are reported. Hypothalamic suppression followed by inappropriate positive feedback, and then hyperprolactinemia and ovarian failure are the most frequently encountered etiologies. Other etiologies are diverse and numerically less frequent. Amenorrhea after use of oral contraceptives, or postpill amenorrhea, occurred in 77 (29%) of all patients. The average age of presentation, prior menstrual history, associated morbidity, and subsequent reproductive potential of each diagnostic group are reported. Adult-onset amenorrhea has a less significant impact on future wellbeing than was reported for a similar-sized group of patients whose amenorrhea developed as a result of pubertal aberrancy.

    Insulin resistance potentiates the association between obesity and childhood asthma, but this relationship appears inconsistent in relatively small studies of adults. We investigated effect modification in adults using the National Health and Nutrition Examination Survey 2003-2012, a large, nationally representative database.Insulin resistance and a history of physician-diagnosed current asthma were obtained from 12 421 adults, ages 18-85 years. We used logistic regression to determine associations between obesity and current asthma, adjusting for age, sex, race/ethnicity, poverty income ratio and smoking status. An interaction term evaluated effect modification by insulin resistance of the obesity-asthma association.As expected, obesity was positively associated with current asthma. Insulin resistance modified this association, with obesity measured as body mass index, waist circumference or waist-to-height ratio. The relationship between obesity and current asthma was stronger with increasing insulin resistance tertiles (OR 2.05, 95% CI 2.76-3.00; p-value for interaction 0.03). This association was robust to adjustments for other components of the metabolic syndrome (hypertriglyceridaemia, hypertension, hyperglycaemia and systemic inflammation). None of these components were themselves effect modifiers of the obesity-asthma association.In this large, nationally representative sample, insulin resistance modified the association between obesity and current asthma in adults. Targeting insulin resistance may represent a novel therapeutic strategy for obese patients with asthma.

    Acne vulgaris is usually considered as a skin disorder that primarily affects adolescents reaching a peak at the age of 14–17 years in females and 16–19 years in males. However, recent epidemiologic studies have shown that a significant number of female patients aged >25 years experience acne. As it is regarded as a disease of teenagers, adults are more apprehensive and experience social anxiety. Hence, adult onset acne has become a matter of concern. PMID:27512185

  14. Physical activity in adults with controlled and uncontrolled asthma as compared to healthy adults: a cross-sectional study

    PubMed Central

    2013-01-01

    Background Though exercise-induced bronchoconstriction is common among asthmatics, physical activity (PA) seems important in asthma management. Still, various studies point at avoidance of sports and certain daily life activities like walking stairs, even by patients with mild symptoms. We aimed to compare physical activity levels between healthy subjects and asthmatics with controlled and uncontrolled disease. Methods Data on asthma and PA were drawn from the Portuguese National Asthma Survey. The short telephone version of the International Physical Activity Questionnaire (IPAQ) was used to measure PA levels. Current asthma was defined as self-reported asthma and at least one of these criteria: one or more asthma symptoms in the last twelve months, currently taking asthma medication or an asthma medical appointment in the previous twelve months. Controlled asthma was defined as a CARAT global score > 24 or a CARAT second factor score ≤ 16. Healthy subjects were defined as individuals without atopy, heart disease or any respiratory symptom. X2 and Mann–Whitney/Kruskall-Wallis tests were used to compare groups. Logistic regression analyses were performed to assess relations between asthma status and PA dimensions. Results A total of 606 non-asthmatics, 125 controlled and 78 uncontrolled asthmatic subjects were included. In both genders, overall PA level did not differ significantly between groups. Controlled (men) and uncontrolled (women) asthmatics did more vigorous PA than healthy respondents. Male controlled asthmatics also did more moderate PA. Crude logistic regression showed positive relations between daily sitting time, vigorous and moderate PA and controlled asthma in men and between vigorous PA and uncontrolled asthma in women. After adjustments for confounders, moderate PA remained a predictor of controlled asthma in men, while vigorous PA doubled the risk of uncontrolled asthma in women. Conclusion Our study showed that adult asthmatics, independent

    Background: Although it is well established that air pollutants can exacerbate asthma, the link with new asthma onset in children is less clear. Objective: We assessed the association between the onset of childhood asthma with both time of birth and time-varying exposures to outdoor air pollutants. Method: An open cohort of children born in the province of Québec, Canada, was created using linked medical–administrative databases. New cases of asthma were defined as one hospital discharge with a diagnosis of asthma or two physician claims for asthma within a 2 year period. Annual ozone (O3) levels were estimated at the child’s residence for all births 1999–2010, and nitrogen dioxide (NO2) levels during 1996–2006 were estimated for births on the Montreal Island. Satellite based concentrations of fine particles (PM2.5) were estimated at a 10 km × 10 km resolution and assigned to residential postal codes throughout the province (1996–2011). Hazard ratios (HRs) were assessed with Cox models for the exposure at the birth address and for the time-dependent exposure. We performed an indirect adjustment for secondhand smoke (SHS). Results: We followed 1,183,865 children (7,752,083 person-years), of whom 162,752 became asthmatic. After controlling for sex and material and social deprivation, HRs for an interquartile range increase in exposure at the birth address to NO2 (5.45 ppb), O3 (3.22 ppb), and PM2.5 (6.50 μg/m3) were 1.04 (95% CI: 1.02, 1.05), 1.11 (95% CI: 1.10, 1.12), and 1.31 (95% CI: 1.28, 1.33), respectively. Effects of O3 and PM2.5 estimated with time-varying Cox models were similar to those estimated using exposure at birth, whereas the effect of NO2 was slightly stronger (HR = 1.07; 95% CI: 1.05, 1.09). Conclusions: Asthma onset in children appears to be associated with residential exposure to PM2.5, O3 and NO2.

    Binge drinking and poor mental health may affect adherence to treatment for individuals with asthma. The purposes were to (a) examine the relationship of self-reported binge drinking and mental health to adherence to daily asthma control medications and (b) identify other demographic and health-related factors associated with asthma control medication adherence. Secondary analyses of 2003 adult California Health Interview Survey data were undertaken, and these analyses identified 3.2 million California adults who had been told by a physician they had asthma. Of these, approximately 1.7 million were symptomatic. Binge drinking significantly predicted medication nonadherence among California adults with symptomatic asthma (OR = .63, 95% CI = .45-.89), whereas poor mental health did not. Other predictors of nonadherence (odds ratios < 1, p < .05) included being overweight, younger age, having some college education, being a current smoker, and having no usual source of medical care. Predictors of adherence (odds ratios > 1, p < .05) were older age, more frequent asthma symptoms, more ER visits, more missed work days, being African American, and being a non-citizen. Intervention efforts could be directed toward improving medication adherence among adult asthma patients who engage in risky health behaviors such as binge drinking. Also at risk for medication nonadherence and therefore good targets for asthma control medication management interventions are adults who are overweight, younger (18-44 age range), have some college education, and no usual source of medical care.

    2016-01-01

    This is an updated guideline for the diagnosis and management of asthma, developed by the Saudi Initiative for Asthma (SINA) group, a subsidiary of the Saudi Thoracic Society. The main objective of SINA is to have guidelines that are up to date, simple to understand and easy to use by nonasthma specialists, including primary care and general practice physicians. SINA approach is mainly based on symptom control and assessment of risk as it is the ultimate goal of treatment. The new SINA guidelines include updates of acute and chronic asthma management, with more emphasis on the use of asthma control in the management of asthma in adults and children, inclusion of a new medication appendix, and keeping consistency on the management at different age groups. The section on asthma in children is rewritten and expanded where the approach is stratified based on the age. The guidelines are constructed based on the available evidence, local literature, and the current situation in Saudi Arabia. There is also an emphasis on patient–doctor partnership in the management that also includes a self-management plan. PMID:26933455

    Studies have shown that asthma in children is caused by environmental and genetic factors. In adult asthma, risk factors were less well recognized. Likewise, in Thailand, data in adult asthma is limited. This study aimed to evaluate risk factors, determine skin reactivities to allergens, and assess concomitant allergy among adult asthma in Phitsanulok, a major city in the lower northern Thailand. Five hundred and thirteen Naresuan University staff members and students completed 2 sets of questionnaires and underwent allergy skin prick tests. The first set of questionnaires was standardized Thai version of ISAAC questionnaire for identifying asthma, allergic rhinitis, and atopic eczema. The second set was modified from ISAAC phase II questionnaire to identify asthma risk factors. Fifty-eight subjects (11.6%) were identified as having physician's diagnosed asthma and 89 subjects (17.7%) wheezed in the past 12 months. Among 89 subjects, 14.4% wheezed more than once a month, 45.6% had wheezes interfering with sleep. Concomitant allergic rhinitis, rhinoconjunctivitis and atopic eczema among these asthma subjects were 82.5%, 67.9%, and 14.9%, respectively. Eighty seven point nine percent of asthmatic subjects had positive skin reactivities to at least one allergen. Two of the most common allergens were house dust mites and cockroaches. Maternal smoking during pregnancy, smoking among family members, and family history of allergy were statistically significant risks for developing asthma, while having a rice field around the residence represented a significant protective factor. In conclusion, high prevalence of asthma presented in Phitsanulok and many asthmatic subjects were partly controlled or uncontrolled. The environment such as a rice field could protect against asthma, however atopy and smoking exposure were significant risks for asthma development

    Asthma 1-2-3 is a newly-developed low-literacy multimedia education tool designed to promote asthma self-care concepts among African American adults. An expert panel (n = 10) informed content development for the tool. The video script and storyboard imagery were shown to 30 African Americans recruited from the American Lung Association, whose reactions and comments guided further revisions. The final version was pilot tested in three diverse community settings in Chicago to determine the efficacy of Asthma 1-2-3 at improving patient understanding of asthma and its symptoms. In all, 130 adults participated in the pilot test. Knowledge scores significantly improved from pretest to posttest following presentation of the developed tool for subjects across all literacy levels (Pretest: Mean = 4.2 [SD = 1.6]; Posttest: M = 6.8 [SD = 2.0], P < 0.001). Symptom pathophysiology concepts were the least understood. Individuals with low literacy had less total knowledge score gains compared to those with marginal and adequate literacy (1.8, 2.6, and 3.2 respectively; P = 0.002). The multimedia tool significantly improved understanding of asthma. Individuals with limited literacy may require additional instruction, repeated viewing, or added tangible cues (i.e. supplementary print materials) to support knowledge retention. In general, feedback from the target population was particularly helpful in the development of the tool and its initial evaluation, and should be considered as a necessary step in the creation of other patient education materials.

    Asthma is increasing in prevalence worldwide and results in significant use of healthcare resources. Although most patients with asthma can be adequately treated with inhaled corticosteroids, an important number of patients require additional therapy and an increasing number of options are available. A further minority of patients develop severe persistent asthma which remains difficult to manage despite current pharmacological therapies. This review discusses the various treatment options currently available for each stage of asthma severity, highlights some of the limitations of current management, and outlines directions which may improve the management of asthma in the future.

    Susceptibility genes of asthma may be more successfully identified by studying subgroups of phenotypically similar asthma patients. This study aims to identify single nucleotide polymorphisms (SNPs) associated with asthma in French Canadian adult women. A pooling-based genome-wide association study was performed in 240 allergic asthmatic and 120 allergic nonasthmatic women. The top associated SNPs were selected for individual genotyping in an extended cohort of 349 asthmatic and 261 nonasthmatic women. The functional impact of asthma-associated SNPs was investigated in a lung expression quantitative trait loci (eQTL) mapping study (n = 1035). Twenty-one of the 38 SNPs tested by individual genotyping showed P values lower than 0.05 for association with asthma. Cis-eQTL analyses supported the functional contribution of rs17801353 associated with C3AR1 (P = 7.90E − 10). The asthma risk allele for rs17801353 is associated with higher mRNA expression levels of C3AR1 in lung tissue. In silico functional characterization of the asthma-associated SNPs also supported the contribution of C3AR1 and additional genes including SYNE1, LINGO2, and IFNG-AS1. This pooling-based GWAS in French Canadian adult women followed by lung eQTL mapping suggested C3AR1 as a functional locus associated with asthma. Additional susceptibility genes were suggested in this homogenous subgroup of asthma patients. PMID:27445529

    The underdiagnosis of asthma has not been well studied previously. The purpose of this study was to determine whether the diagnosis of asthma had been made previously in young adults who were subsequently shown to have asthma upon entering military service. Questionnaires were answered by all airmen basic referred to the Allergy-Immunology Clinic at Wilford Hall United States Air Force Medical Center over an 11-month period. There were 192 airmen basic referred to rule out asthma, primarily because of respiratory symptoms with exercise. These airmen were evaluated by history, physical examination, pulmonary function tests and, in 67%, by histamine or exercise challenge test also. In those diagnosed with asthma, the evaluating allergist then determined whether the diagnosis of asthma had been made previously considered or not considered. In airmen basic diagnosed by our clinic with asthma, the diagnosis had been made previously in 45%, considered in 25%, and not considered in 30%. Undiagnosed asthmatic airmen tended to have mild and primarily exercise-induced disease. We conclude that there is a high incidence of underdiagnosis of asthma in the population studied. Exercise-induced asthma accounted for most of the undiagnosed asthma.

  4. Difficult asthma in adults: recognition and approaches to management.

    PubMed

    Difficult asthma must be distinguished from severe asthma. It is then important in patients with suspected difficult asthma to ensure that the diagnosis is correct, and that if the patient has asthma that the attributed symptoms are indeed all genuinely due to the asthma and not to coexisting physical or psychogenic respiratory conditions. It is also important to be alert when there is discordance between symptoms and objective lung function in order to recognize both poor perceivers and over-reactors. Difficult asthma can occur in patients with objectively mild, moderate or severe disease, but the consequences are most dramatic in patients with severe asthma. Asthma may be difficult for the patient, for the clinician or both because of disease factors, doctor or nurse therapist factors, and/or patient factors. Investigation requires access to the full range of respiratory, imaging and allergy tests. It also requires a multidisciplinary approach involving ear, nose and throat specialists and speech therapists, and access to psychiatric and psychological assessment and therapies. Poor compliance is associated with significantly poorer asthma and asthma-related health outcomes. Poor compliance can be recognized in two-thirds of such patients by their not attending scheduled appointments. Poor compliance is significantly associated with anxiety, social deprivation and adverse family circumstances, and these characteristics and adversities probably contribute to the poorly compliant behaviour. In difficult asthma it is important to identify and manage the condition causing the symptoms rather than prescribing more and more asthma therapy. Recognizing psychosocial adversity is essential. A structured approach is essential. There remains a small number of patients with genuine steroid-resistant asthma, some with predominately neutrophilic rather than eosinophilic airway inflammation, and others for whom the secondary gain of continuing symptoms is overwhelming. There is

    Neuronal intranuclear inclusion disease (NIID) is a slowly progressive neurodegenerative disease characterized by eosinophilic hyaline intranuclear inclusions in the central and peripheral nervous system, and also in the visceral organs. NIID has been considered to be a heterogeneous disease because of the highly variable clinical manifestations, and ante-mortem diagnosis has been difficult. However, since we reported the usefulness of skin biopsy for the diagnosis of NIID, the number of NIID diagnoses has increased, in particular adult-onset NIID. In this study, we studied 57 cases of adult-onset NIID and described their clinical and pathological features. We analysed both NIID cases diagnosed by post-mortem dissection and by ante-mortem skin biopsy based on the presence of characteristic eosinophilic, hyaline and ubiquitin-positive intanuclear inclusion: 38 sporadic cases and 19 familial cases, from six families. In the sporadic NIID cases with onset age from 51 to 76, dementia was the most prominent initial symptom (94.7%) as designated ‘dementia dominant group’, followed by miosis, ataxia and unconsciousness. Muscle weakness and sensory disturbance were also observed. It was observed that, in familial NIID cases with onset age less than 40 years, muscle weakness was seen most frequently (100%), as designated ‘limb weakness group’, followed by sensory disturbance, miosis, bladder dysfunction, and dementia. In familial cases with more than 40 years of onset age, dementia was most prominent (100%). Elevated cerebrospinal fluid protein and abnormal nerve conduction were frequently observed in both sporadic and familial NIID cases. Head magnetic resonance imaging showed high intensity signal in corticomedullary junction in diffusion-weighted image in both sporadic and familial NIID cases, a strong clue to the diagnosis. All of the dementia dominant cases presented with this type of leukoencephalopathy on head magnetic resonance imaging. Both sporadic and

    Pigmentary type of orthochromatic leukodystrophy (POLD) is an adult-onset leukodystrophy, characterized pathologically by the presence of glial and microglial cytoplasmic pigment inclusions. The complete phenotype, genotype and pathogenetic mechanisms in POLD have not been elucidated. We followed for 18 years a woman with autopsy-proven POLD, who presented with 'frontal' dementia and spasticity. Her further course was marked by progressive mutism, apraxia and seizures. Her sister had died of the same disease after a much more rapidly progressing course. These sisters had primary infertility with pathologic evidence of streak ovaries. Diagnosis was confirmed in both cases by post-mortem examination. POLD is a rare cause of adult-onset leukodystrophy presenting with dementia. Ovarian dysgenesis is extremely rare in the absence of demonstrable chromosomal abnormalities and extends the clinical spectrum of POLD.

    Adult onset glioma is a rare cancer which occurs more frequently in Caucasians than African Americans, and in men than women. The etiology of this disease is largely unknown. Exposure to ionizing radiation is the only well established environmental risk factor, and this factor explains only a small percentage of cases. Several recent studies have reported an association between season of birth and glioma risk. This paper reviews the plausibility of evidence focusing on the seasonal interrelation of farming, allergies, viruses, vitamin D, diet, birth weight, and handedness. To date, a convincing explanation for the occurrence of adult gliomas decades after a seasonal exposure at birth remains elusive. PMID:20623001

    IMPORTANCE In asthma and other diseases, vitamin D insufficiency is associated with adverse outcomes. It is not known if supplementing inhaled corticosteroids with oral vitamin D3 improves outcomes in patients with asthma and vitamin D insufficiency. OBJECTIVE To evaluate if vitamin D supplementation would improve the clinical efficacy of inhaled corticosteroids in patients with symptomatic asthma and lower vitamin D levels. DESIGN, SETTING, AND PARTICIPANTS The VIDA (Vitamin D Add-on Therapy Enhances Corticosteroid Responsiveness in Asthma) randomized, double-blind, parallel, placebo-controlled trial studying adult patients with symptomatic asthma and a serum 25-hydroxyvitamin D level of less than 30 ng/mL was conducted across 9 academic US medical centers in the National Heart, Lung, and Blood Institute’s AsthmaNet network, with enrollment starting in April 2011 and follow-up complete by January 2014. After a run-in period that included treatment with an inhaled corticosteroid, 408 patients were randomized. INTERVENTIONS Oral vitamin D3 (100 000 IU once, then 4000 IU/d for 28 weeks; n = 201) or placebo (n = 207) was added to inhaled ciclesonide (320 µg/d). If asthma control was achieved after 12 weeks, ciclesonide was tapered to 160 µg/d for 8 weeks, then to 80 µg/d for 8 weeks if asthma control was maintained. MAIN OUTCOMES AND MEASURES The primary outcome was time to first asthma treatment failure (a composite outcome of decline in lung function and increases in use of β-agonists, systemic corticosteroids, and health care). RESULTS Treatment with vitamin D3 did not alter the rate of first treatment failure during 28 weeks (28%[95% CI, 21%-34%] with vitamin D3 vs 29% [95% CI, 23%–35%] with placebo; adjusted hazard ratio, 0.9 [95% CI, 0.6–1.3]). Of 14 prespecified secondary outcomes, 9 were analyzed, including asthma exacerbation; of those 9, the only statistically significant outcome was a small difference in the overall dose of ciclesonide required to

    Summary Viral infections affect wheezing and asthma in children and adults of all ages. In infancy, wheezing illnesses are usually viral in origin, and children with more severe wheezing episodes are more likely to develop recurrent episodes of asthma and to develop asthma later in childhood. Children who develop allergen-specific immunoglobulin E (allergic sensitization), and those who wheeze with rhinoviruses (HRV) are at especially high risk for asthma. In older children and adults, HRV infections generally cause relatively mild respiratory illnesses and yet contribute to acute and potentially severe exacerbations in patients with asthma. These findings underline the importance of understanding the synergistic nature of allergic sensitization and infections with HRV in infants relative to the onset of asthma and in children and adults with respect to exacerbations of asthma. This review discusses clinical and experimental evidence of virus/allergen interactions and evaluates theories which relate immunologic responses to respiratory viruses and allergens to the pathogenesis and disease activity of asthma. Greater understanding of the relationship between viral respiratory infections, allergic inflammation, and asthma is likely to suggest new strategies for the prevention and treatment of asthma.

    This pilot study aims to provide effect size confidence intervals, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy of Dietary Approaches to Stop Hypertension (DASH) as adjunct therapy to standard care for adults with uncontrolled asthma. The DASH diet encompasses foods (e.g., fresh fruit, vegetables, and nuts) and antioxidant nutrients (e.g., vitamins A, C, E, and zinc) with potential benefits for persons with asthma, but it is unknown whether the whole diet is beneficial. Participants (n = 90) will be randomized to receive usual care alone or combined with a DASH intervention consisting of 8 group and 3 individual sessions during the first 3 months, followed by at least monthly phone consultations for another 3 months. Follow-up assessments will occur at 3 and 6 months. The primary outcome measure is the 7-item Juniper Asthma Control Questionnaire, a validated composite measure of daytime and nocturnal symptoms, activity limitations, rescue medication use, and percentage predicted forced expiratory volume in 1 second. We will explore changes in inflammatory markers important to asthma pathophysiology (e.g., fractional exhaled nitric oxide) and their potential to mediate the intervention effect on disease control. We will also conduct pre-specified subgroup analyses by genotype (e.g., polymorphisms on the glutathione S transferase gene) and phenotype (e.g., atopy, obesity). By evaluating a dietary pattern approach to improving asthma control, this study could advance the evidence base for refining clinical guidelines and public health recommendations regarding the role of dietary modifications in asthma management.

  12. Precipitation of asthma attacks in Melanesian adults by sodium metabisulphite.

    Seven Melanesian asthmatic patients were challenged with substances that have been shown to precipitate asthma attacks in asthma patients in developed countries. Patients were challenged in a double-blind fashion using placebo and active substances. The active substances were tartrazine, sodium metabisulphite, aspirin and betel nut. All 7 patients were challenged with tartrazine and sodium metabisulphite; 5 were challenged with aspirin also, but only 2 were challenged with betel nut. Asthma attacks were precipitated by sodium metabisulphite in 3 patients. No other substances precipitated asthma. As sodium metabisulphite is a common food additive, these results suggest that processed foods introduced into developing countries may have an important role in precipitating asthma attacks in susceptible persons.

  13. New onset of idiopathic bilateral ear tics in an adult.

    2009-04-01

    Tic disorders are commonly considered to be childhood syndromes. Newly presenting tic disorders during adulthood are uncommon and mostly described in relation to an acquired brain lesion or as incidental tics, particularly in context with other neurological or psychiatric diseases. Tic disorder involving the ears is extremely uncommon with only few studies in English literature. In the present case, we describe an adult patient with new-onset idiopathic tics disorder involving both ears, causing social embarrassment. In addition, our patient had recent onset of the tics without any childhood or family history of tic disorders. The single most important component of management is an accurate diagnosis. At the same time, tics should be differentiated from other movement disorders such as chorea, stereotypy, and dystonias.

    Fever, rash, and arthritis may be components of the prodrome of viral hepatitis. In the absence of jaundice and abnormal liver function tests, this form of polyarthritis is easily confused with primary autoimmune diseases. Whereas the association of systemic illness with musculoskeletal symptoms and numerous viral infections is well known, such an association with hepatitis A has only been rarely reported. We describe a case of hepatitis A infection mimicking adult onset Still's disease, and review the pathogenesis and differential diagnosis of Still's disease and the extraarticular manifestations of hepatitis.

    U-BIOPRED is a European Union consortium of 20 academic institutions, 11 pharmaceutical companies and six patient organisations with the objective of improving the understanding of asthma disease mechanisms using a systems biology approach.This cross-sectional assessment of adults with severe asthma, mild/moderate asthma and healthy controls from 11 European countries consisted of analyses of patient-reported outcomes, lung function, blood and airway inflammatory measurements.Patients with severe asthma (nonsmokers, n=311; smokers/ex-smokers, n=110) had more symptoms and exacerbations compared to patients with mild/moderate disease (n=88) (2.5 exacerbations versus 0.4 in the preceding 12 months; p<0.001), with worse quality of life, and higher levels of anxiety and depression. They also had a higher incidence of nasal polyps and gastro-oesophageal reflux with lower lung function. Sputum eosinophil count was higher in severe asthma compared to mild/moderate asthma (median count 2.99% versus 1.05%; p=0.004) despite treatment with higher doses of inhaled and/or oral corticosteroids.Consistent with other severe asthma cohorts, U-BIOPRED is characterised by poor symptom control, increased comorbidity and airway inflammation, despite high levels of treatment. It is well suited to identify asthma phenotypes using the array of "omic" datasets that are at the core of this systems medicine approach.

  16. Relationship between anxiety, depression, and morbidity in adult asthma patients

    2001-01-01

    BACKGROUND—Symptoms of disease reported by patients reflect the effects of the disease process within the individual and the person's physical and mental ability to tolerate or otherwise cope with the limitations on their functioning. This study examines the relationship between asthma symptoms, disease severity, and psychological status in patients being managed in routine primary healthcare settings.
METHODS—One hundred and fourteen subjects from four GP practices, two inner city and two suburban, were studied. Symptoms were assessed by means of the Asthma Quality of Life questionnaire (AQLQ) and a locally devised Q score, and psychological status with the Hospital Anxiety and Depression (HAD) scale. Spirometric values and details of current asthma treatment (BTS asthma guidelines treatment step) were recorded as markers of asthma severity.
RESULTS—Symptoms as measured by AQLQ correlated with peak expiratory flow (rS = 0.40) and with BTS guidelines treatment step (rS =0.25). Similarly, the Q score correlated with peak expiratory flow (rS = 0.44) and with BTS guidelines treatment step (rS =0.42). Similar levels of correlation of forced expiratory volume in one second (FEV1) with symptoms were reported. HAD anxiety and depression scores also correlated to a similar extent with these two symptom scores, but there was hardly any correlation with lung function. Logistic regression analysis showed that HAD scores help to explain symptom scores over and above the effects of lung function and BTS guidelines treatment step. Symptoms, depression, and anxiety were higher for inner city patients while little difference was observed in objective measures of asthma.
CONCLUSIONS—Asthma guidelines suggest that changing levels of symptoms should be used to monitor the effectiveness of treatment. These data suggest that reported symptoms may be misleading and unreliable because they may reflect non-asthma factors that cannot be expected to respond to changes in

    Objective Aerobic exercise can improve cardiovascular fitness and does not seem to be detrimental to patients with asthma, though its role in changing asthma control and inflammatory profiles is unclear. The main hypothesis of the current randomised controlled trial is that aerobic exercise will be superior to usual care in improving asthma control. Key secondary outcomes are asthma quality of life and inflammatory profiles. Design A total of 104 sedentary adults with physician-diagnosed asthma will be recruited. Eligible participants will undergo a series of baseline assessments including: the asthma control questionnaire; the asthma quality-of-life questionnaire and the inflammatory profile (assessed from both the blood and sputum samples). On completion of the assessments, participants will be randomised (1:1 allocation) to either 12-weeks of usual care or usual care plus aerobic exercise. Aerobic exercise will consist of three supervised training sessions per week. Each session will consist of taking a short-acting bronchodilator, 10 min of warm-up, 40 min of aerobic exercise (50–75% of heart rate reserve for weeks 1–4, then 70–85% for weeks 5–12) and a 10 min cool-down. Within 1 week of completion, participants will be reassessed (same battery as at baseline). Analyses will assess the difference between the two intervention arms on postintervention levels of asthma control, quality of life and inflammation, adjusting for age, baseline inhaled corticosteroid prescription, body weight change and pretreatment dependent variable level. Missing data will be handled using standard multiple imputation techniques. Ethics and dissemination The study has been approved by all relevant research ethics boards. Written consent will be obtained from all participants who will be able to withdraw at any time. Results The result will be disseminated to three groups of stakeholder groups: (1) the scientific and professional community; (2) the research

    Food allergy can result in life-threatening anaphylaxis. Atopic dermatitis (AD) causes intense itching and impaired quality of life. Previous studies have shown that patients with classical early-onset AD tend to develop food allergy and that 10% of adults with food allergies have concomitant AD. However, it is not known whether late-onset food allergy leads to adult-onset AD, a recently recognized disease entity. Using an initial cohort of one-million subjects, this study retrospectively followed-up 2851 patients with food allergy (age > 12 years) for 14 years and compared them with 11,404 matched controls. While 2.8% (81) of the 2851 food allergy patients developed AD, only 2.0% (227) of the 11,404 controls developed AD. Multivariate regression analysis showed that food allergy patients were more likely to develop AD (adjusted hazard ratio = 2.49, p < 0.0001). Controls had a 1.99% risk of developing AD, while food allergy patients had a significantly higher risk (7.18% and 3.46% for patients with ≥3 and <3 food allergy claims, respectively) of developing adult-onset AD. This is the first study to describe the chronological and dose-dependent associations between food allergy in adolescence and the development of adult-onset AD. PMID:28035995

    Objective Many asthma patients suffer from chronic conditions other than asthma. We investigated the specific contribution of common comorbidities on mortality and morbidity in adult asthma. Methods In an observational study of adults with incident asthma identified between 1999 and 2003 using National Veterans Affairs and Centers for Medicare and Medicaid Services encounter databases (n=25,975, follow-up 3.0±1.7 years), association between 13 most prevalent comorbidities (hypertension, ischemic heart disease (IHD), osteoarthritis, rheumatoid arthritis, diabetes, mental disorders, substance/drug abuse, enlarged prostate, depression, cancer, alcoholism, HIV, and heart failure) and 4 conditions previously associated with asthma (sleep apnea, gastroesophageal reflux disease (GERD), rhinitis, and sinusitis) and mortality, hospitalizations and asthma exacerbations were assessed using multivariate regression analyses adjusted for other clinically important covariates. Results HIV followed by alcoholism and mental disorders among 18–45 years old, and heart failure, diabetes, IHD, and cancer among those ≥65 years old were associated with an increased risk of all-cause mortality. Many conditions were associated with increased risk for all-cause hospitalizations, but the increased risk was consistent across all ages for mental disorders. For asthma exacerbations, mental disorder followed by substance abuse and IHD were associated with increased risk among those 18–45 years old, and chronic sinusitis, mental disorder, and IHD among those ≥65 years old. GERD was associated with decreased risk for asthma exacerbation in all ages. Conclusions Many comorbidities are associated with poor outcome in adult asthmatics and their effect differs by age. Mental disorders are associated with increased risk of mortality and morbidity across ages. PMID:24432868

    BACKGROUND: We sought to investigate the degree to which cognitive skills explain associations between health literacy and asthma-related medication use among older adults with asthma. METHODS: Patients aged ≥ 60 years receiving care at eight outpatient clinics (primary care, geriatrics, pulmonology, allergy, and immunology) in New York, New York, and Chicago, Illinois, were recruited to participate in structured, in-person interviews as part of the Asthma Beliefs and Literacy in the Elderly (ABLE) study (n = 425). Behaviors related to medication use were investigated, including adherence to prescribed regimens, metered-dose inhaler (MDI) technique, and dry powder inhaler (DPI) technique. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Cognitive function was assessed in terms of fluid (working memory, processing speed, executive function) and crystallized (verbal) ability. RESULTS: The mean age of participants was 68 years; 40% were Hispanic and 30% non-Hispanic black. More than one-third (38%) were adherent to their controller medication, 53% demonstrated proper DPI technique, and 38% demonstrated correct MDI technique. In multivariable analyses, limited literacy was associated with poorer adherence to controller medication (OR, 2.3; 95% CI, 1.29-4.08) and incorrect DPI (OR, 3.51; 95% CI, 1.81-6.83) and MDI (OR, 1.64; 95% CI, 1.01-2.65) techniques. Fluid and crystallized abilities were independently associated with medication behaviors. However, when fluid abilities were added to the model, literacy associations were reduced. CONCLUSIONS: Among older patients with asthma, interventions to promote proper medication use should simplify tasks and patient roles to overcome cognitive load and suboptimal performance in self-care.

    Asthma and allergic rhinitis often coexist and are increasing worldwide, particularly among the younger generation. Although the prevalences of adult asthma and allergic rhinitis and their risk factors have been reported, there have been few studies focusing on young adults. The aim of this study was to evaluate the prevalences of asthma and allergic rhinitis and their associated factors in Japanese young adults. A questionnaire survey of new students at Hokkaido University about the presence of current wheeze and rhinitis and a history of several viral infections during childhood was conducted in 2008 and 2010. The prevalences of wheeze and rhinitis and their associated factors were evaluated. Of 4076 nonsmoking subjects aged 18-25 years, 261 (6.4%) had current wheeze and 1373 (33.7%) had allergic rhinitis. On multivariate analyses, current wheeze was associated with high body mass index (BMI), atopic dermatitis, allergic rhinitis, food allergy, and a history of measles infection. In contrast, allergic rhinitis was associated with low BMI, current wheeze, atopic dermatitis, food allergy, and no history of measles. When subjects were classified into four groups by the presence or absence of wheeze and rhinitis, both high BMI and a history of measles were positively associated with wheeze without rhinitis but negatively associated with rhinitis without wheeze. High BMI and past measles infection showed contrasting associations with asthma and allergic rhinitis in nonsmoking young adults. It is important to not only recognize the common pathophysiological characteristics of asthma and allergic rhinitis but also to understand their differences.

    The aim of the study was to identify genetic variants associated with refined asthma phenotypes enabling multiple features of the disease to be taken into account. Latent class analysis (LCA) was applied in 3001 adults ever having asthma recruited in the frame of three epidemiological surveys (the European Community Respiratory Health Survey (ECRHS), the Swiss Study on Air Pollution and Lung Disease in Adults (SAPALDIA) and the Epidemiological Study on the Genetics and Environment of Asthma (EGEA)). 14 personal and phenotypic characteristics, gathered from questionnaires and clinical examination, were used. A genome-wide association study was conducted for each LCA-derived asthma phenotype, compared to subjects without asthma (n=3474). The LCA identified four adult asthma phenotypes, mainly characterised by disease activity, age of asthma onset and atopic status. Associations of genome-wide significance (p<1.25 × 10(-7)) were observed between "active adult-onset nonallergic asthma" and rs9851461 flanking CD200 (3q13.2) and between "inactive/mild nonallergic asthma" and rs2579931 flanking GRIK2 (6q16.3). Borderline significant results (2.5 × 10(-7) < p <8.2 × 10(-7)) were observed between three single nucleotide polymorphisms (SNPs) in the ALCAM region (3q13.11) and "active adult-onset nonallergic asthma". These results were consistent across studies. 15 SNPs identified in previous genome-wide association studies of asthma have been replicated with at least one asthma phenotype, most of them with the "active allergic asthma" phenotype. Our results provide evidence that a better understanding of asthma phenotypic heterogeneity helps to disentangle the genetic heterogeneity of asthma.

    Background. There are limited epidemiological studies evaluating the effect of age at onset on disease features in vitiligo. Objectives. To identify factors associated with adult onset vitiligo in comparison with childhood onset vitiligo. Patients and Methods. We retrospectively collected medical records of 191 patients. Such records included clinical examination, personal and familial medical history, laboratory evaluations, concomitant vitiligo treatment and drug assumption. Results. 123 patients with a disease onset after the age of 40 (adult onset vitiligo) were compared with 68 patients who developed vitiligo before the age of 12 (childhood onset vitiligo). Multivariate analysis revealed that personal history of thyroid diseases (P = 0.04; OR 0.4), stress at onset (P = 0.002; OR = 0.34), personal history of autoimmune thyroid disease (ATD) (P = 0.003; OR = 0.23), and thyroid nodules (P = 0.001; OR 0.90) were independently associated with adult onset vitiligo, whereas family history of dermatological diseases (P = 0.003; OR = 2.87) and Koebner phenomenon (P < 0.001; OR = 4.73) with childhood onset vitiligo. Moreover, in the adult onset group, concomitant thyroid disease preceded vitiligo in a statistically significant number of patients (P = 0.014). Conclusions. Childhood onset and adult onset vitiligo have different clinical features. In particular, ATD and thyroid nodules were significantly associated with adult onset vitiligo, suggesting that a thyroid screening should be recommended in this group of patients. PMID:27747240

    A 9-y-old, colony-bred, female vervet monkey (Chlorocebus sabaeus) presented with a 6-y history of open-mouth breathing, tachypnea, and sibilant wheezing. These symptoms did not significantly affect her activity or quality of life. Thoracic radiographs and results of bronchoalveolar lavage supported the diagnosis of asthma. Treatment comprising intramuscular prednisolone (tapered over 2 mo from twice daily to every other day), inhaled salmeterol–fluticasone (25 µg–250 µg per actuation twice daily) by mask, and a metered dose inhaler was successful in restoring a normal respiratory pattern. Despite the availability of several primate models of human asthma, this case represents the first report of spontaneous asthma in a NHP. PMID:26884413

    Abstract Adult-onset Still's disease (AOSD) is often refractory to standard therapy. Anakinra (ANK), an interleukin-1 receptor antagonist, has demonstrated efficacy in single cases and small series of AOSD. We assessed the efficacy of ANK in a series of AOSD patients. Multicenter retrospective open-label study. ANK was used due to lack of efficacy to standard synthetic immunosuppressive drugs and in some cases also to at least 1 biologic agent. Forty-one patients (26 women/15 men) were recruited. They had a mean age of 34.4 ± 14 years and a median [interquartile range (IQR)] AOSD duration of 3.5 [2–6] years before ANK onset. At that time the most common clinical features were joint manifestations 87.8%, fever 78%, and cutaneous rash 58.5%. ANK yielded rapid and maintained clinical and laboratory improvement. After 1 year of therapy, the frequency of joint and cutaneous manifestations had decreased to 41.5% and to 7.3% respectively, fever from 78% to 14.6%, anemia from 56.1% to 9.8%, and lymphadenopathy from 26.8% to 4.9%. A dramatic improvement of laboratory parameters was also achieved. The median [IQR] prednisone dose was also reduced from 20 [11.3–47.5] mg/day at ANK onset to 5 [0–10] at 12 months. After a median [IQR] follow-up of 16 [5–50] months, the most important side effects were cutaneous manifestations (n = 8), mild leukopenia (n = 3), myopathy (n = 1), and infections (n = 5). ANK is associated with rapid and maintained clinical and laboratory improvement, even in nonresponders to other biologic agents. However, joint manifestations are more refractory than the systemic manifestations. PMID:26426623

    Abstract Adult-onset Still disease (AOSD) is a systemic autoimmune disease (AIID) that can develop after exposure to infectious agents. Genital human papillomavirus (HPV) infection has been reported to induce or exacerbate AIIDs, such as systemic lupus erythematosus (SLE). No guidelines are available for the management of genital warts in AOSD. Case report and literature review. We report a patient who was diagnosed AOSD in the setting of refractory and recurrent genital HPV infection, demonstrating a possible link between HPV infection and AOSD. In addition, we also discuss the management of genital warts in patients with AOSD. To the best of our knowledge, no previous cases of AOSD with genital HPV infection have been reported in literature. We then conclude that the patient AOSD may be triggered by primary HPV infection. Larger number of patient samples is needed to confirm whether HPV could trigger AOSD. PMID:27082556

    Asthma phenotypes based on age-of-onset may be differently influenced by the interaction between variation in toll-like receptor (TLR)/CD14 genes and environmental microbes. We examined the associations between single-nucleotide polymorphisms (SNP) in the TLR/CD14 genes and asthma, and their interaction with proxies of microbial exposure (childhood farm exposure and childhood rural environment). Ten SNPs in four genes (TLR2, TLR4, TLR6, CD14) were genotyped for 1,116 participants from the Tasmanian Longitudinal Health Study (TAHS). Using prospectively collected information, asthma was classified as never, early- (before 13 years) or late-onset (after 13 years). Information on childhood farm exposure/childhood rural environment was collected at baseline. Those with early-onset asthma were more likely to be males, had a family history of allergy and a personal history of childhood atopy. We found significant interaction between TLR6 SNPs and childhood farm exposure. For those with childhood farm exposure, carriers of the TLR6-rs1039559 T-allele (p-interaction = 0.009) and TLR6-rs5743810 C-allele (p-interaction = 0.02) were associated with lower risk of early-onset asthma. We suggest the findings to be interpreted as hypothesis-generating as the interaction effect did not withstand correction for multiple testing. In this large, population-based longitudinal study, we found that the risk of early- and late-onset asthma is differently influenced by the interaction between childhood farming exposure and genetic variations.

    OBJECTIVE: To develop a set of comprehensive, standardized evidence-based guidelines for the assessment and treatment of acute asthma in adults in the emergency setting. OPTIONS: The use of medications was evaluated by class, dose, route, onset of action and optimal mode of delivery. The use of objective measurements and clinical features to assess response to therapy were evaluated in relation to the decision to admit or discharge the patient or arrange for follow-up care. OUTCOMES: Control of symptoms and disease reflected in hospital admission rates, frequency of treatment failures following discharge, resolution of symptoms and improvement of spirometric test results. EVIDENCE: Previous guidelines, articles retrieved through a search of MEDLINE, emergency medical abstracts and information from members of the expert panel were reviewed by members of the Canadian Association of Emergency Physicians (CAEP) and the Canadian Thoracic Society. Where evidence was not available, consensus was reached by the expert panel. The resulting guidelines were reviewed by members of the parent organizations. VALUES: The evidence-based methods and values of the Canadian Task Force on the Periodic Health Examination were used. BENEFITS, HARMS AND COSTS: As many as 80% of the approximate 400 deaths from asthma each year in Canada are felt to be preventable. The use of guidelines, aggressive emergency management and consistent use of available options at discharge are expected to decrease the rates of unnecessary hospital admissions and return visits to emergency departments because of treatment failures. Substantial decreases in costs are expected from the use of less expensive drugs, or drug delivery systems, fewer hospital admissions and earlier return to full activity after discharge. RECOMMENDATIONS: Beta2-agonists are the first-line therapy for the management of acute asthma in the emergency department (grade A recommendation). Bronchodilators should be administered by the

    Objective: Inhaler technique comprises a set of procedures for drug delivery to the respiratory system. The oral inhalation of medications is the first-line treatment for lung diseases. Using the proper inhaler technique ensures sufficient drug deposition in the distal airways, optimizing therapeutic effects and reducing side effects. The purposes of this study were to assess inhaler technique in pediatric and adult patients with asthma; to determine the most common errors in each group of patients; and to compare the results between the two groups. Methods: This was a descriptive cross-sectional study. Using a ten-step protocol, we assessed inhaler technique in 135 pediatric asthma patients and 128 adult asthma patients. Results: The most common error among the pediatric patients was failing to execute a 10-s breath-hold after inhalation, whereas the most common error among the adult patients was failing to exhale fully before using the inhaler. Conclusions: Pediatric asthma patients appear to perform most of the inhaler technique steps correctly. However, the same does not seem to be true for adult patients. PMID:26578130

    We investigated the effects of both ambient air pollution and traffic noise on adult asthma prevalence, using harmonised data from three European cohort studies established in 2006-2013 (HUNT3, Lifelines and UK Biobank).Residential exposures to ambient air pollution (particulate matter with aerodynamic diameter ≤10 µm (PM10) and nitrogen dioxide (NO2)) were estimated by a pan-European Land Use Regression model for 2007. Traffic noise for 2009 was modelled at home addresses by adapting a standardised noise assessment framework (CNOSSOS-EU). A cross-sectional analysis of 646 731 participants aged ≥20 years was undertaken using DataSHIELD to pool data for individual-level analysis via a "compute to the data" approach. Multivariate logistic regression models were fitted to assess the effects of each exposure on lifetime and current asthma prevalence.PM10 or NO2 higher by 10 µg·m(-3) was associated with 12.8% (95% CI 9.5-16.3%) and 1.9% (95% CI 1.1-2.8%) higher lifetime asthma prevalence, respectively, independent of confounders. Effects were larger in those aged ≥50 years, ever-smokers and less educated. Noise exposure was not significantly associated with asthma prevalence.This study suggests that long-term ambient PM10 exposure is associated with asthma prevalence in western European adults. Traffic noise is not associated with asthma prevalence, but its potential to impact on asthma exacerbations needs further investigation.

    Abstract Parenchymal lung involvement (PLI) in adult-onset Still's disease (AOSD) has seldom, if ever, been studied. We examine here retrospective cohort AOSD cases and present a review of the literature (1971–2014) on AOSD-related PLI cases. Patients with PLI were identified in 57 AOSD cases. For inclusion, the patients had to fulfill Yamaguchi or Fautrel classification criteria, show respiratory symptoms, and have imaging evidence of pulmonary involvement, and data allowing exclusion of infectious, cardiogenic, toxic, or iatrogenic cause of PLI should be available. This AOSD + PLI group was compared with a control group (non–PLI-complicated AOSD cases from the same cohort). AOSD + PLI was found in 3 out of the 57 patients with AOSD (5.3%) and the literature mentioned 27 patients. Among these 30 AOSD + PLI cases, 12 presented an acute respiratory distress syndrome (ARDS) and the remaining 18 another PLI. In the latter, a nonspecific interstitial pneumonia computed tomography pattern prevailed in the lower lobes, pulmonary function tests showed a restrictive lung function, the alveolar differential cell count was neutrophilic in half of the cases, and the histological findings were consistent with bronchiolitis and nonspecific interstitial pneumonia. Corticosteroids were fully efficient in all but 3 patients. Ten out of 12 ARDS cases occurred during the first year of the disease course. All ARDS-complicated AOSD cases received corticosteroids with favorable outcomes in 10 (2 deceased). Most PLIs occurred during the systemic onset of AOSD. PLI may occur in 5% of AOSDs, of which ARDS is the most severe. Very often, corticosteroids are efficient in controlling this complication. PMID:27472698

    BACKGROUND: In 2010, the Canadian Thoracic Society (CTS) published a Consensus Summary for the diagnosis and management of asthma in children six years of age and older, and adults, including an updated Asthma Management Continuum. The CTS Asthma Clinical Assembly subsequently began a formal clinical practice guideline update process, focusing, in this first iteration, on topics of controversy and/or gaps in the previous guidelines. METHODS: Four clinical questions were identified as a focus for the updated guideline: the role of noninvasive measurements of airway inflammation for the adjustment of anti-inflammatory therapy; the initiation of adjunct therapy to inhaled corticosteroids (ICS) for uncontrolled asthma; the role of a single inhaler of an ICS/long-acting beta2-agonist combination as a reliever, and as a reliever and a controller; and the escalation of controller medication for acute loss of asthma control as part of a self-management action plan. The expert panel followed an adaptation process to identify and appraise existing guidelines on the specified topics. In addition, literature searches were performed to identify relevant systematic reviews and randomized controlled trials. The panel formally assessed and graded the evidence, and made 34 recommendations. RESULTS: The updated guideline recommendations outline a role for inclusion of assessment of sputum eosinophils, in addition to standard measures of asthma control, to guide adjustment of controller therapy in adults with moderate to severe asthma. Appraisal of the evidence regarding which adjunct controller therapy to add to ICS and at what ICS dose to begin adjunct therapy in children and adults with poor asthma control supported the 2010 CTS Consensus Summary recommendations. New recommendations for the adjustment of controller medication within written action plans are provided. Finally, priority areas for future research were identified. CONCLUSIONS: The present clinical practice guideline

    Objective We aimed to investigate the associations of physical activity and change in physical activity with incident asthma in a cohort of Norwegian adults. Design We conducted a prospective cohort study using data on self-reported physical activity from 3 waves of the Nord-Trøndelag Health Study. Physical activity was reported at the first and second surveys (1985–1986 and 1995–1997). Physical activity was defined from the second survey as inactive or active and the active group was further defined as very low, low, moderate and high. Change in physical activity was defined from the first and second surveys. Setting A large population-based health survey in Norway. Participants We followed 18 894 adults over 11 years who were free from asthma at baseline in 1995–1997. Outcome Incident asthma was reported in the third survey (2006–2008). Results The cumulative incidence of asthma was 3.6% over the 11 years. The adjusted OR for incident asthma among active participants compared with inactive participants was 0.95 (95% CI 0.69 to 1.34). The adjusted OR for those who were active in the first or second survey versus those who were inactive in both surveys was 0.64 (95% CI 0.34 to 1.38); however, this association was strongly attenuated in sensitivity analysis (OR 0.93, 95% CI 0.38 to 3.09). Conclusions We did not observe statistically significant associations of physical activity or change in physical activity with incident asthma in adults over the 11-year follow-up. PMID:27864254

    Neurodegeneration with brain iron accumulation (NBIA) is a heterogeneous group of disorders varied in genetic etiologies, clinical presentations, and radiological features. NBIA is an iron homeostasis disorder with progressive iron accumulation in the central nervous systems and is clinically characterized by extrapyramidal movement abnormalities, retinal pigmentary changes, and cognitive impairment. Panthothenate kinase-associated neurodegeneration (Hallervorden-Spatz disease) is the commonest disorder of NBIA with a prevalence of one-three per million. Clinically, it is classified into early-onset childhood, atypical late-onset, and adult-onset type. Adult-onset type is rarer. We report the first case of adult-onset panthothenate kinase-associated neurodegeneration in Hong Kong in a 28-year-old Chinese man who presented with pure young-onset parkinsonism. Magnetic resonance imaging (MRI) of the brain showed the presence of eye-of-the-tiger sign. Two compound heterozygous mutations PANK2 NM_153638.2: c.445G > T; NP_705902.2: p.E149X and PANK2 NM_153638.2: c.1133A > G; NP_705902.2: p.D378G were detected. Parkinsonism per se is a very heterogeneous phenotypic group. In view of the readily available genetic analysis of PANK2, panthothenate kinase-associated neurodegeneration should be considered in adult patients with young-onset parkinsonism with or without the eye-of-the-tiger sign. The exact diagnosis offers a different management approach and genetic counseling. NBIA is likely under- or misdiagnosed in Hong Kong Chinese.

    Adult onset Still’s disease (AOSD) is a chronic inflammatory disorder involving multiple systems. The symptoms mimic those of lymphomas, therefore, the diagnosis of lymphoma needs to be excluded prior to establishing the diagnosis of AOSD. Another similar condition is dermatopathic lymphadenopathy (DL). In DL, the histopathological appearance of lymph node biopsy may also mimic AOSD. The DL is associated with several systemic pathologies, such as malignant lymphomas, and rarely AOSD. We present a case of a 43-year-old male presented with 3 months history of fatigue, fever, and lymphadenopathy. Initial work-up satisfactorily met the criteria for diagnosis of AOSD. But considering the well-known association of DL with hematological malignancies, detailed pathological studies were considered, including tumor markers to rule out the possibility of malignancy. The patient was started on steroids and showed remarkable recovery within 2 weeks. Evaluation of malignant lymphomas in a patient with DL is important, in order to diagnose AOSD and rule out hematological malignancy. PMID:27761568

    Abstract Rationale: Hypophosphatemic osteomalacia (HO) is a metabolic bone disease, exhibiting different etiologies such as genetic mutation, tumor induction, dysimmunity, or renal disease. Sjogren's syndrome (SS) is a connective tissue disorder commonly involving exocrine glands; however kidney involvement is also encountered, leading to abnormal phosphorus metabolism, even HO. Patient concerns: A 47-year-old female patient presented progressively worsening pain in the chest wall, back and bilateral lower extremities as well as muscle weakness was referred to our department. Diagnoses, interventions and outcomes: Due to the laboratory test results, radiographic findings and pathologic results, she was diagnosed with adult-onset HO associated with SS. She was then treated with alkalinization, steroids, neutral phosphate, calcium supplements together with activated vitamin D. So far, she recovered uneventfully with relieved pain and increased serum phosphorus level. Lessons: HO may be secondary to renal tubular acidosis of SS patients, and it might be a diagnostic challenge when the kidney involvement in SS is latent and precede the typical sicca symptoms.

    Objectives. We estimated the extent to which socioeconomic status (SES) gradients in adult asthma and rhinitis outcomes can be explained by home and neighborhood environmental factors. Methods. Using survey data for 515 adults with either asthma or rhinitis, or both, we examined environmental mediators of SES associations with disease severity, using the Severity of Asthma Scale, and health-related quality of life (HRQL), using the Rhinasthma Scale. We defined SES on the basis of education and household income. Potential environmental mediators included home type and ownership, exposures to allergens and irritants, and a summary measure of perceived neighborhood problems. We modeled each outcome as a function of SES, and controlled for age, gender, and potential mediators. Results. Gradients in SES were apparent in disease severity and HRQL. Living in a rented house partially mediated the SES gradient for both severity and HRQL (P < .01). Higher perceived levels of neighborhood problems were associated with poorer HRQL and partially mediated the income–HRQL relationship (P < .01). Conclusions. Differences in home and neighborhood environments partially explained associations of SES with adult asthma and rhinitis outcomes. PMID:23237178

  1. ‘Get Your Life Back’: process and impact evaluation of an asthma social marketing campaign targeting older adults

    2013-01-01

    Background Asthma in older adults is underdiagnosed and poorly self-managed. This population has little knowledge about the key symptoms, the prevalence among older adults, and the serious consequences of untreated asthma. The purpose of this study was to undertake a multifaceted evaluation of a social marketing campaign to increase asthma awareness among older adults in a regional Australian community. Methods A cohort of older adults in an intervention region (n = 316) and a control region (n = 394) were surveyed immediately prior to and following the social marketing campaign. Campaign awareness, message recall, materials recognition, and actions taken as a result of the campaign were assessed in both regions. Asthma knowledge and perceptions, experience of asthma symptoms, and general health were also assessed in both regions at baseline and follow-up. Analyses were conducted to explore the effects of the campaign in the intervention region, and to examine outcomes among different audience segments. Results The survey data showed that those in the target segments (Wheezers and Strugglers) had better message recall, and were more likely to report having taken action to control their respiratory symptoms. The campaign significantly increased the number of calls to an asthma information line from the target audience in the intervention community. Conclusions A theory-based social marketing campaign conducted over 3-months increased the asthma information seeking behaviours of older adults in the intervention community compared to the control community. Recommendations are outlined for future community health promotion campaigns targeting older adults. PMID:23947479

    Rationale: The effect of weight loss on asthma in obese adults warrants rigorous investigation. Objectives: To examine an evidence-based, practical, and comprehensive lifestyle intervention targeting modest weight loss and increased physical activity for asthma control. Methods: The trial randomized 330 obese adults with uncontrolled asthma to receive usual care enhanced with a pedometer, a weight scale, information about existing weight management services at the participating clinics, and an asthma education DVD, or with these tools plus the 12-month intervention. Measurements and Main Results: The primary outcome was change in Asthma Control Questionnaire (ACQ) scores from baseline to 12 months. Participants (mean [SD] age, 47.6 [12.4] yr) were 70.6% women, 20.0% non-Hispanic black, 20.3% Hispanic/Latino, and 8.2% Asian/Pacific Islander. At baseline, they were obese (mean [SD] body mass index, 37.5 [5.9] kg/m2) and had uncontrolled asthma (Asthma Control Test score, 15.1 [3.8]). Compared with control subjects, intervention participants achieved significantly greater mean weight loss (±SE) (intervention, −4.0 ± 0.8 kg vs. control, −2.1 ± 0.8 kg; P = 0.01) and increased leisure-time activity (intervention, 418.2 ± 110.6 metabolic equivalent task–min/wk vs. control, 178.8 ± 109.1 metabolic equivalent task–min/wk; P = 0.05) at 12 months. But between-treatment mean (±SE) differences were not significant for ACQ changes (intervention, –0.3 ± 0.1 vs. control, –0.2 ± 0.1; P = 0.92) from baseline (mean [SD], 1.4 [0.8]), nor for any other clinical asthma outcomes (e.g., spirometric results and asthma exacerbations). Among all participants regardless of treatment assignment, weight loss of 10% or greater was associated with a Cohen d effect of 0.76 and with 3.78 (95% confidence interval, 1.72–8.31) times the odds of achieving clinically significant reductions (i.e., ≥0.5) on ACQ as stable weight (<3% loss or gain from

    Background We have previously identified four distinct groups of asthma patients in Korean cohorts using cluster analysis: (A) smoking asthma, (B) severe obstructive asthma, (C) early-onset atopic asthma, and (D) late-onset mild asthma. Methods and Results A longitudinal analysis of each cluster in a Korean adult asthma cohort was performed to investigate the clinical significance of asthma clusters over 12 months. Cluster A showed relatively high asthma control test (ACT) scores but relatively low FEV1 scores, despite a high percentage of systemic corticosteroid use. Cluster B had the lowest mean FEV1, ACT, and the quality of life questionnaire for adult Korean asthmatics (QLQAKA) scores throughout the year, even though the percentage of systemic corticosteroid use was the highest among the four clusters. Cluster C was ranked second in terms of FEV1, with the second lowest percentage of systemic corticosteroid use, and showed a marked improvement in subjective symptoms over time. Cluster D consistently showed the highest FEV1, the lowest systemic corticosteroid use, and had high ACT and QLQAKA scores. Conclusion Our asthma clusters had clinical significance with consistency among clusters over 12 months. These distinctive phenotypes may be useful in classifying asthma in real practice.

    Objectives Occupational asthma remains relatively under-recognized in India with little or no information regarding preventable causes. We studied occupations with an increased prevalence of self-reported asthma among adult men and women in India. Methods Analysis is based on 64 725 men aged 15–54 years and 52 994 women aged 15–49 years who participated in India’s third National Family Health Survey, 2005–2006, and reported their current occupation. Prevalence odds ratios (ORs) for specific occupations and asthma were estimated using multivariate logistic regression, separately for men and women, adjusting for age, education, household wealth index, current tobacco smoking, cooking fuel use, rural/urban residence and access to healthcare. Results The prevalence of asthma among the working population was 1.9%. The highest odds ratios for asthma were found among men in the plant and machine operators and assemblers major occupation category (OR: 1.67; 95% CI: 1.14–2.45; p = 0.009). Men working in occupation subcategories of machine operators and assemblers (OR: 1.85; 95% CI: 1.24–2.76; p = 0.002) and mining, construction, manufacturing and transport (OR: 1.33; 95% CI: 1.00–1.77; p = 0.051) were at the highest risk of asthma. Reduced odds of asthma prevalence in men was observed among extraction and building trades workers (OR: 0.72; 95% CI: 0.53–0.97; p = 0.029). Among women none of the occupation categories or subcategories was found significant for asthma risk. Men and women employed in high-risk occupations were not at a higher risk of asthma when compared with those in low-risk occupations. Conclusions This large population-based, nationally representative cross-sectional study has confirmed findings from high income countries showing high prevalence of asthma in men in a number of occupational categories and subcategories; however, with no evidence of increased risks for women in the same occupations.

    Although an association between exposure to phthalates in house dust and childhood asthma or allergies has been reported in recent years, there have been no reports of these associations focusing on both adults and children. We aimed to investigate the relationships between phthalate levels in Japanese dwellings and the prevalence of asthma and allergies in both children and adult inhabitants in a cross-sectional study. The levels of seven phthalates in floor dust and multi-surface dust in 156 single-family homes were measured. According to a self-reported questionnaire, the prevalence of bronchial asthma, allergic rhinitis, allergic conjunctivitis, and atopic dermatitis in the 2 years preceding the study was 4.7%, 18.6%, 7.6%, and 10.3%, respectively. After evaluating the interaction effects of age and exposure categories with generalized liner mixed models, interaction effects were obtained for DiNP and bronchial asthma in adults (Pinteraction=0.028) and for DMP and allergic rhinitis in children (Pinteraction=0.015). Although not statistically significant, children had higher ORs of allergic rhinitis for DiNP, allergic conjunctivitis for DEHP, and atopic dermatitis for DiBP and BBzP than adults, and liner associations were observed (Ptrend<0.05). On the other hand, adults had a higher OR for atopic dermatitis and DEHP compared to children. No significant associations were found in phthalates levels collected from multi-surfaces. This study suggests that the levels of DMP, DEHP, DiBP, and BBzP in floor dust were associated with the prevalence of allergic rhinitis, conjunctivitis, and atopic dermatitis in children, and children are more vulnerable to phthalate exposure via household floor dust than are adults. The results from this study were shown by cross-sectional nature of the analyses and elaborate assessments for metabolism of phthalates were not considered. Further studies are needed to advance our understanding of phthalate toxicity.

    Objective The age-at-onset criterion for separation anxiety disorder was removed in DSM-5, making it timely to examine the epidemiology of separation anxiety disorder as a disorder with onsets spanning the life course, using cross-country data. Method The sample included 38,993 adults in 18 countries in the World Health Organization (WHO) World Mental Health Surveys. The WHO Composite International Diagnostic Interview was used to assess a range of DSM-IV disorders that included an expanded definition of separation anxiety disorder allowing onsets in adulthood. Analyses focused on prevalence, age at onset, comorbidity, predictors of onset and persistence, and separation anxiety-related role impairment. Results Lifetime separation anxiety disorder prevalence averaged 4.8% across countries (interquartile range [25th–75th percentiles]=1.4%–6.4%), with 43.1% of lifetime onsets occurring after age 18. Significant time-lagged associations were found between earlier separation anxiety disorder and subsequent onset of internalizing and externalizing DSM-IV disorders and conversely between these disorders and subsequent onset of separation anxiety disorder. Other consistently significant predictors of lifetime separation anxiety disorder included female gender, retrospectively reported childhood adversities, and lifetime traumatic events. These predictors were largely comparable for separation anxiety disorder onsets in childhood, adolescence, and adulthood and across country income groups. Twelve-month separation anxiety disorder prevalence was considerably lower than lifetime prevalence (1.0% of the total sample; interquartile range=0.2%–1.2%). Severe separation anxiety-related 12-month role impairment was significantly more common in the presence (42.4%) than absence (18.3%) of 12-month comorbidity. Conclusions Separation anxiety disorder is a common and highly comorbid disorder that can have onset across the lifespan. Childhood adversity and lifetime trauma are

    The effects of immunization with killed influenza virus vaccine were assessed by comparison with placebo in a double-blind study of 318 adult patients with chronic asthma. The patients were randomly allocated to active vaccine and placebo. No difference was observed in peak expiratory flow rate or in clinical symptoms of bronchial obstruction between the groups receiving active vaccine and placebo during the first week after immunization. The data were analyzed separately for age, sex, duration of the disease, hypersensitivity to aspirin (acetylsalicylic acid), atopic status, patients with a history of attacks of asthma induced by viral infections, patients with a diurnal variation of baseline peak expiratory flow of 20 percent or more, and patients receiving continuous oral steroid medication, but none of these factors seemed to predict any short-term adverse effects of vaccination. Follow-up for eight months after the vaccination revealed no differences in asthmatic symptoms between the patients treated with active vaccine and those receiving placebo. The antiviral antibody response to vaccination was normal. The possible protection provided by the vaccination against exacerbation of asthma induced by influenza could not be evaluated, since the influenza epidemic expected during the season failed to occur in Finland. It is concluded that immunization with killed influenza vaccine is safe and is not associated with any significant side effects in adult patients with chronic asthma.

    Oxidative stress has a recognized role in the pathophysiology of asthma. Recently, interest has increased in the assessment of pH and airway oxidative stress markers. Collection of exhaled breath condensate (EBC) and quantification of biomarkers in breath samples can potentially indicate lung disease activity and help in the study of airway inflammation, and asthma severity. Levels of oxidative stress markers in the EBC have been systematically evaluated in children with asthma; however, there is no such systematic review conducted for adult asthma. A systematic review of oxidative stress markers measured in EBC of adult asthma was conducted, and studies were identified by searching MEDLINE and SCOPUS databases. Sixteen papers met the inclusion criteria. Concentrations of exhaled hydrogen ions, nitric oxide products, hydrogen peroxide and 8-isoprostanes were generally elevated and related to lower lung function tests in adults with asthma compared to healthy subjects. Assessment of EBC markers may be a noninvasive approach to evaluate airway inflammation, exacerbations, and disease severity of asthma, and to monitor the effectiveness of anti-inflammatory treatment regimens. Longitudinal studies, using standardized analytical techniques for EBC collection, are required to establish reference values for the interpretation of EBC markers in the context of asthma.

    BACKGROUND Long-acting beta-agonist (LABA) therapy improves symptoms in patients whose asthma is poorly controlled by an inhaled glucocorticoid alone. Alternative treatments for adults with uncontrolled asthma are needed. METHODS In a three-way, double-blind, triple-dummy crossover trial involving 210 patients with asthma, we evaluated the addition of tiotropium bromide (a long-acting anticholinergic agent approved for the treatment of chronic obstructive pulmonary disease but not asthma) to an inhaled glucocorticoid, as compared with a doubling of the dose of the inhaled glucocorticoid (primary superiority comparison) or the addition of the LABA salmeterol (secondary noninferiority comparison). RESULTS The use of tiotropium resulted in a superior primary outcome, as compared with a doubling of the dose of an inhaled glucocorticoid, as assessed by measuring the morning peak expiratory flow (PEF), with a mean difference of 25.8 liters per minute (P<0.001) and superiority in most secondary outcomes, including evening PEF, with a difference of 35.3 liters per minute (P<0.001); the proportion of asthma-control days, with a difference of 0.079 (P = 0.01); the forced expiratory volume in 1 second (FEV1) before bronchodilation, with a difference of 0.10 liters (P = 0.004); and daily symptom scores, with a difference of −0.11 points (P<0.001). The addition of tiotropium was also noninferior to the addition of salmeterol for all assessed outcomes and increased the prebronchodilator FEV1 more than did salmeterol, with a difference of 0.11 liters (P = 0.003). CONCLUSIONS When added to an inhaled glucocorticoid, tiotropium improved symptoms and lung function in patients with inadequately controlled asthma. Its effects appeared to be equivalent to those with the addition of salmeterol. (Funded by the National Heart, Lung, and Blood Institute; ClinicalTrials.gov number, NCT00565266.) PMID:20979471

    BACKGROUND—It is the general impression that the prevalence of asthma has increased during recent decades. A study was undertaken to investigate asthma prevalence, respiratory symptoms, and lung function in young adults in the City of Copenhagen 15 years apart.
METHODS—Men and women aged 20-35 years were sampled from the general population living in a defined area of central Copenhagen. The first examination took place in 1976-8 and comprised 1034 subjects (response rate 67.2%). A new sample comprising 1104 subjects (response rate 62.6%) from exactly the same area was examined 15 years later in 1991-4. All participants answered a questionnaire on respiratory symptoms and diseases and performed spirometric tests with measurement of forced expiratory volume in one second (FEV1) and forced vital capacity (FVC).
RESULTS—The prevalence of self-reported asthma increased from 1.5% in the first survey to 4.8% in the second survey (p<0.001). Asthmatic subjects had, on average, poorer lung function than non-asthmatic subjects in terms of FEV1 and this difference was more pronounced in the second survey than in the first (10.0% of predicted versus 2.4% of predicted). Smoking decreased significantly from 62% in 1976-8 to 45% in 1991-4 (p<0.001).
CONCLUSIONS—The prevalence of self-reported asthma has increased significantly among young adults in Copenhagen over a 15 year period. The severity of asthma, as judged by the level of FEV1, has also increased. These findings cannot be explained by changes in smoking habits.

    Abstract The diagnosis of adult-onset Still's disease (AOSD) can be very difficult. There are no specific tests available, and diagnosis is usually based on a symptom complex and the well-described typical evanescent rash seen in the majority of patients. However, in recent years, other atypical cutaneous manifestations of AOSD have been reported. These atypical skin eruptions often present in addition to the typical evanescent rash but may also be the only skin manifestation, resulting in delayed diagnosis because of under-recognition. In this study, we present 3 new cases of AOSD with atypical cutaneous manifestations diagnosed during a 30-year period in our department and review 78 additional cases previously reported (PubMed 1990–2016). These 81 patients form the basis of the present analysis. The overall prevalence of atypical cutaneous manifestations in our AOSD population was 14%. These manifestations may appear at any time over the course of the disease, and usually occur in patients who have persistent and severe disease, with a considerable frequency of clinical complications (23%), including serositis, myopericarditis, lung involvement, abdominal pain, neurologic involvement, and reactive hemophagocytic syndrome. The most representative and frequent lesion among the nonclassical skin rashes is the development of persistent pruritic papules and/or plaques. Interestingly, these lesions show a distinctive histological pattern. Other, less frequently observed lesions include urticaria and urticaria-like eruptions, generalized or widespread non-pruritic persistent erythema, vesiculopustular eruptions, a widespread peau d’orange appearance of the skin, and edema of the eyelids mimicking dermatomyositis without any accompanying skin lesion. The great majority of these patients required medium or high doses of glucocorticoids (including intravenous methylprednisolone pulse therapy in some cases) and, in nearly 40%, a more potent or maintenance immunotherapy

    Background: Relationships between air quality and health are well-described, but little information is available about the joint associations between particulate air pollution, ambient temperature, and respiratory morbidity. Objectives: We evaluated associations between concentrations of particulate matter ≤ 2.5 μm in diameter (PM2.5) and exacerbation of existing asthma and modification of the associations by ambient air temperature. Methods: Data from 50,356 adult respondents to the Asthma Call-back Survey from 2006–2010 were linked by interview date and county of residence to estimates of daily averages of PM2.5 and maximum air temperature. Associations between 14-day average PM2.5 and the presence of any asthma symptoms during the 14 days leading up to and including the interview date were evaluated using binomial regression. We explored variation by air temperature using similar models, stratified into quintiles of the 14-day average maximum temperature. Results: Among adults with active asthma, 57.1% reported asthma symptoms within the past 14 days, and 14-day average PM2.5 ≥ 7.07 μg/m3 was associated with an estimated 4–5% higher asthma symptom prevalence. In the range of 4.00–7.06 μg/m3 of PM2.5, each 1-μg/m3 increase was associated with a 3.4% [95% confidence interval (CI): 1.1, 5.7] increase in symptom prevalence; across categories of temperature from 1.1 to 80.5°F, each 1-μg/m3 increase was associated with increased symptom prevalence (1.1–44.4°F: 7.9%; 44.5–58.6°F: 6.9%; 58.7–70.1°F: 2.9%; 70.2–80.5°F: 7.3%). Conclusions: These results suggest that each unit increase in PM2.5 may be associated with an increase in the prevalence of asthma symptoms, even at levels as low as 4.00–7.06 μg/m3.

    Kimura's disease (KD) is an angiolymphoid proliferative disorder of soft tissue with eosinophilia, with a predilection for head and neck regions in young Oriental men. Kidney disease is thought to be rare in KD. About a case of adult-onset nephrotic syndrome with minimal change disease, we comment Kimura's disease and its associated kidney damage. Kimura disease should be suspected and included in the diagnosis of adult-onset nephrotic syndrome with minimal change disease.

    Background Not providing adequate patient education interventions to asthma patients remains a major care gap. To help asthma patients and caregivers discuss inhaled controller medication use, our team has previously developed a decision aid (DA). We sought to assess whether adding this DA to education interventions improved knowledge, decisional conflict, and asthma control among adults with asthma. Methods A parallel clinical trial (NCT02516449). We recruited adults with asthma, aged 18 to 65 years, prescribed inhaled controller medication to optimize asthma control. Educators randomly allocated participants either to the education + DA or to the education group. At baseline and two-month follow-up, we measured asthma knowledge (primary outcome) with a validated self-administered questionnaire (score –37 to +37). Secondary outcomes included decisional conflict and asthma control. Blinded assessors collected data. Between the two time points, the within- and between-group changes were estimated by generalized linear mixed models. Results Fifty-one participants (response rate: 53%; age: 44 ± 13 years; women: n = 32) were randomized either to the education + DA group (n = 26) or to the education group (n = 25), and included in statistical analyses. Between baseline and follow-up, mean [95% CI] knowledge scores increased from 21.5 [19.9–23.2] to 25.1 [23.1–27.0] in the education + DA group (P = 0.0002) and from 24.0 [22.3–25.7] to 26.0 [24.0–28.0] in the education group (P = 0.0298). In both of the groups, decisional conflict and asthma control improved. There were no differences between groups. Conclusions Education improved knowledge, decisional conflict, and asthma control whether the DA was added or not. PMID:28107540

    Asthma has been associated with increased cardiovascular disease (CVD) risk. The authors ascertained the association of asthma with CVD and the roles that sex, concurrent allergy, and asthma medications may play in this association. They assembled a cohort of 203,595 Northern California adults with asthma and a parallel asthma-free referent cohort (matched 1:1 on age, sex, and race/ethnicity); both cohorts were followed for incident nonfatal or fatal CVD and all-cause mortality from January 1, 1996, through December 31, 2008. Each cohort was 66% female and 47% white. After adjustment for age, sex, race/ethnicity, cardiac risk factors, and comorbid allergy, asthma was associated with a 1.40-fold (95% confidence interval (CI): 1.35, 1.45) increased hazard of coronary heart disease, a 1.20-fold (95% CI: 1.15, 1.25) hazard of cerebrovascular disease, a 2.14-fold (95% CI: 2.06, 2.22) hazard of heart failure, and a 3.28-fold (95% CI: 3.15, 3.41) hazard of all-cause mortality. Stronger associations were noted among women. Comorbid allergy predicted CVD but did not synergistically increase the CVD risk associated with asthma. Only asthma patients using asthma medications (particularly those on oral corticosteroids alone or in combination) were at enhanced risk of CVD. In conclusion, asthma was prospectively associated with increased risk of major CVD. Modifying effects were noted for sex and asthma medication use but not for comorbid allergy.

    Different genes are associated with categorical classifications of asthma severity. However, continuous outcomes should be used to catch the heterogeneity of asthma phenotypes and to increase the power in association studies. Accordingly, the aim of this study was to evaluate the association between single nucleotide polymorphisms (SNPs) in candidate gene regions and continuous measures of asthma severity, in adult patients from the general population. In the Gene Environment Interactions in Respiratory Diseases (GEIRD) study (www.geird.org), 326 subjects (aged 20-64) with ever asthma were identified from the general population in Verona (Italy) between 2007 and 2010. A panel of 236 SNPs tagging 51 candidate gene regions (including one or more genes) was analysed. A symptom and treatment score (STS) and pre-bronchodilator FEV1% predicted were used as continuous measures of asthma severity. The association of each SNP with STS and FEV1% predicted was tested by fitting quasi-gamma and linear regression models, respectively, with gender, body mass index and smoking habits as potential confounders. The Simes multiple-test procedure was used for controlling the false discovery rate (FDR). SNP rs848 in the IL13 gene region (IL5/RAD50/IL13/IL4) was associated with STS (TG/GG vs TT genotype: uncorrected p-value = 0.00006, FDR-corrected p-value = 0.04), whereas rs20541 in the same gene region, in linkage disequilibrium with rs848 (r(2) = 0.94) in our sample, did not reach the statistical significance after adjusting for multiple testing (TC/CC vs TT: uncorrected p-value = 0.0003, FDR-corrected p-value = 0.09). Polymorphisms in other gene regions showed a non-significant moderate association with STS (IL12B, TNS1) or lung function (SERPINE2, GATA3, IL5, NPNT, FAM13A) only. After adjusting for multiple testing and potential confounders, SNP rs848 in the IL13 gene region is significantly associated with a continuous measure of symptom severity in adult subjects with ever

    Rationale There is conflicting evidence on whether patients with asthma experience an accelerated decline in lung function with age. We examined the association between postbronchodilator lung function, asthma, chronic rhinosinusitis (CRS), and atopy with age using a large European sample. Methods In 17 centers in 11 European countries, case–control studies were nested within representative cross-sectional surveys of adults aged less than 75 years. Representative samples of participants with asthma, CRS or both and controls were assessed for postbronchodilator ventilatory function, smoking history, atopy, and treatment. Multiple regression was used to assess the interactive effects of age and diagnostic group on decline in postbronchodilator ventilatory function. Results A total of 3337 participants provided adequate data (778 with asthma, 399 with CRS, 244 with both asthma and CRS and 1916 controls who had neither asthma nor CRS). Participants with asthma had lower FEV1/FVC (−4.09% (95% CI: −5.02, −3.15, P < 0.001) and a steeper slope of FEV1/FVC against age (−0.14%/annum [95%CI: −0.19, −0.08]) equivalent to smoking 1–2 packs of cigarettes per day. Those with atopy had a slope equivalent to controls. Conclusions People with asthma have a steeper decline in postbronchodilator lung function with age, but neither CRS nor atopy alone were associated with such decline. PMID:24841074

    Bronchial asthma is a chronic airway inflammatory condition with high morbidity, and effective treatments for asthma are limited. Allergen-specific immunotherapy can only induce peripheral immune tolerance and is not sustainable. Exploring new therapeutic strategies is of great clinical importance. Recombinant adenovirus (rAdV) was used as a vector to make cells expressing cytotoxic T lymphocyte-associated antigen-4-immunoglobulin (CTLA4Ig) a soluble CTLA4 immunoglobulin fusion protein. Dendritic cells (DCs) were modified using the rAdVs together with allergens. Then these modified DCs were transplanted to mice before allergen sensitization. The persistence and specificity of immune tolerance were evaluated in mice challenged with asthma allergens at 3 and 7 months. DCs modified by CTLA4Ig showed increased IL-10 secretion, decreased IL-12 secretion, and T cell stimulation in vitro. Mice treated with these DCs in the early neonatal period developed tolerance against the allergens that were used to induce asthma in the adult stage. Asthma symptoms, lung damage, airway reactivity, and inflammatory response all improved. Humoral immunity indices showed that this therapeutic strategy strongly suppressed mice immune responses and was maintained for as long as 7 months. Furthermore, allergen cross-sensitization and challenge experiments demonstrated that this immune tolerance was allergen-specific. Treatment with CTLA4Ig modified DCs in the early neonatal period, inducing persistent and allergen-specific immune tolerance to asthma in adult mice. Our results suggest that it may be possible to develop a vaccine for asthma.

    Many patients with severe refractory asthma, which is insufficiently controlled by additional high-dose of inhaled corticosteroids, require oral corticosteroids and/or immunosuppressant. Clinicians should seek for suitable medications, for its' chronic use may induce high risk of side effects. The purpose of this study was to evaluate the efficacy and safety of nebulized sodium cromoglycate (3-4 times/day) in adult severe asthmatic patients with poorly controlled asthmatic symptoms, despite treatments with high-dose inhaled corticosteroids. Adult patients with severe asthma (n=251) were enrolled in a randomized clinical trial at 30 medical centers in Japan. Isotonic saline was used as placebo. The study was conducted for 10 weeks; with initial 2 weeks of observation followed by 8 weeks of treatments. Efficacy was primarily evaluated based on improvements in morning peak expiratory flow after treatment. All patients who applied inhalation of nebulized sodium cromoglycate (SCG group) or saline (Controls) were treated with high-dose of inhaled corticosteroids (median of beclomethasone dipropionate equivalent dose: 1600 microg/days) and second-line control therapy including oral corticosteroids. There was no significant difference in morning peak expiratory flow between SCG group and controls. However, when patients were stratified into atopic and non-atopic groups, morning peak expiratory flow had significantly improved in the atopic SCG group compared to atopic Controls. Additional inhalation of nebulized sodium cromoglycate with inhaled corticosteroids is effective even in patients with severe atopic asthma. This finding shows that nebulized sodium cromoglycate is expected to be new second-line therapeutic option in severe asthma.

    Hallervorden-Spatz disease is a rare neurological disorder characterized by pyramidal and extrapyramidal manifestations, dysarthria and dementia. Its onset is usually in childhood and most patients have a fatal outcome in few years. A high percentage of cases are hereditary with a recessive autosomal pattern. In the majority of the patients reported, a mutation of the gene that encodes the pantothenate kinase (PANK2) located in the 20p13-p12.3 chromosome that causes iron storage in the basal ganglia of the brain has been found. Its diagnosis is based on clinical symptoms as well as specific MRI imaging findings. The most common psychiatric features are cognitive impairment as well as depressive symptoms. There are few documented cases with psychotic disorders. We present the case of a patient with late onset Hallervorden-Spatz disease and psychotic symptoms that preceded the development of neurological manifestations. The pathophysiology and the treatment of psychotic symptomatology are presented and discussed. Key words: Psicosis, Hallervorden-Spatz, late onset, Basal ganglia.

    OBJECTIVES: To review repeated surveys of the rising prevalence of obstructive lung disease among children and young adults and determine whether systematic biases may explain the observed trends. DESIGN: Review of published reports of repeated cross sectional surveys of asthma and wheezing among children and young adults. The repeated surveys used the same sampling frame, the same definition of outcome variables, and equivalent data collection methods. SETTING: Repeated surveys conducted anywhere in the world. SUBJECTS: All repeated surveys whose last set of results were published in 1983 or later. MAIN OUTCOME MEASURES: Lifetime and current prevalences of asthma and current prevalence of wheezing. The absolute increase (yearly percentage) in the prevalences of asthma and wheezing was calculated and compared between studies. RESULTS: 16 repeated surveys fulfilled the inclusion criteria. 12 reported increases in the current prevalence of asthma (from 0.09% to 0.97% a year) and eight reported increases in the current prevalence of wheezing (from 0.14% to 1.24% a year). Changes in labelling are likely to have occurred for the reporting of asthma, and information biases may have occurred for the reporting of wheezing. Only one study reported an increase in an objective measurement. CONCLUSIONS: The evidence for increased prevalences of asthma and wheezing is weak because the measures used are susceptible to systematic errors. Until repeated surveys incorporating more objective data are available no firm conclusions about increases in obstructive lung disease among children and young adults can be drawn. PMID:9224081

    Niemann-Pick disease type C (NP-C) is an inherited sphingolipidosis characterized by progressive neurological deterioration and early mortality. The symptomatology and disease progression of NP-C are markedly affected by the age at onset of neurological manifestations, and categorization into early-infantile, late-infantile, juvenile, adolescent/adult neurological onset forms can aid evaluation of disease course and responses to therapy. Here, we review current information on the detection, diagnosis, monitoring and treatment of NP-C, with a focus on the adolescent/adult-onset form. A recent analysis indicated that the combined incidence of NP-C related to NPC1 gene mutations (NPC1) and NP-C related to NPC2 gene mutations (NPC2) is approximately 1 case in every 89 000 live births. In particular, late-onset phenotypes might well provide a greater contribution to the overall incidence than has previously been reported. Some neuropathological features in NP-C are held in common with other advanced age-onset diseases such as Alzheimer's disease. Visceral symptoms such as splenomegaly are frequently asymptomatic in patients with adolescent/adult-onset NP-C, and are only occasionally detected during routine ultrasound assessments. In contrast, most patients with adolescent/adult-onset exhibit some degree of slowly progressive, non-disease-specific movement disorders (e.g. cerebellar ataxia), and/or more pathognomonic neurological signs such as vertical supranuclear gaze palsy. An increasing number of adolescent/adult-onset cases have been reported following initial recognition of cognitive impairment and/or psychiatric signs. The recent development and implementation of new clinical screening tools (e.g. the NP-C suspicion index) and biomarkers (e.g. plasma oxysterols) should help identify patients who warrant further investigation and possible treatment.

    Background German cockroach or Blattella germanica is commonly found in homes across the inter-tropical region. The contribution of sensitisation to Blattella germanica in people with asthma in sub-Saharan Africa has not received attention. The aim of this study was to assess the prevalence and investigate the predicting factors of sensitisation to Blattella germanica in patients with asthma in Yaounde, Cameroon. Methods This was a cross-sectional study conducted between January 2012 and June 2013. All patients (aged 15 years and above) with asthma, receiving care at the Yaounde Jamot Hospital and the CEDIMER medical practice during the study period and who had received a prick skin testing for perennial aeroallergens were included in the study. Results The final sample comprised 184 patients including 123 (66.8%) women. The median age (25th-75th percentiles) was 38 (24–54) years. Prick skin test for Blattella germanica was positive in 47 (25.5%) patients. Sensitisation to Blattella germanica was associated with a sensitisation to mite in 41 (87.2%) patients, a sensitisation to Alternaria in 18 (38.3%) patients, and a sensitisation to cat or dog dander in 7 (14.9%) patients. Independent predicting factors of a sensitisation to Blattella germanica were the sensitisation to Blomia tropicalis [adjusted odd ratio (95% confidence interval) 4.10 (1.67-10.04), p = 0.002] and sensitisation to Alternaria [3.67 (1.53-7.46), p = 0.003]. Conclusions Sensitisation to Blattella germanica is present in about a quarter of adult patients with asthma in Yaounde. Sensitisation to Alternaria and Blomia tropicalis appears to be a powerful predicting factor of sensitisation to Blattella germanica in this setting. PMID:25152805

    In young adults, a higher occurrence of asthma-related symptoms was found in an urban than an adjacent suburban area in a survey performed in 1991. The authors now wondered whether such differences could be established in other age groups. The present study (in 1996) included 14,299 subjects, aged 5-75 yrs, of a random sample of the general population in the same two adjacent areas: the centre of Antwerp (Belgium) and its south suburban border. The standardized European Community Respiratory Health Survey (ECRHS) and International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires were used to assess the occurrence of asthma-related symptoms. Higher rates were confirmed in urban compared to suburban Antwerp in adults (20-75 yrs), but no such area differences were found in children (5-8 and 12-15 yrs). Adjustment for a number of recorded risk factors did not seem to affect the area differences in asthma-related symptoms. Comparing the survey results of 1991 and 1996 in 20-44 yr old adults, the findings suggest a slight increase in reported respiratory symptoms in both areas. A higher occurrence of asthma symptoms was observed in the urban than suburban area in adults, but not in children. This might be explained by a progressive effect of long-term exposure to the "urban environment". However, longitudinal studies are necessary to further clarify the factors accounting for these age-related area differences.

    The current study sought to: 1) assess differences in levels of physical and mental health-related quality of life (HRQOL), illness uncertainty, and intrusiveness in adolescents and young adults (AYAs) with allergies and asthma, as well as 2) examine the effect of illness appraisals on HRQOL. Participants were undergraduate students with self-reported allergies (n=74) and asthma (n=74) who completed the Mishel Uncertainty in Illness Scale (MUIS), the Illness Intrusiveness Scale (IIS), and the SF-36 Health Survey Questionnaire. Paired t-tests indicated that AYAs with allergies reported higher levels of illness uncertainty and poorer mental HRQOL than AYAs with asthma; the groups did not differ on reported levels of illness intrusiveness or physical HRQOL. Hierarchical regressions were conducted to examine the relationship between illness appraisals and HRQOL. Results revealed that poorer mental HRQOL was associated with higher illness uncertainty in AYAs with allergies and higher illness intrusiveness in AYAs with asthma. Poorer physical HRQOL was associated with higher illness uncertainty in AYAs with asthma and higher illness intrusiveness in AYAs with allergies and asthma. The current examination suggests that illness appraisals may be differentially related to HRQOL in AYAs with allergies compared to those with asthma.

    Confusion between panic and asthma symptoms can result in serious self-management errors. A cognitive behavior psychophysiological therapy (CBPT) intervention was culturally adapted for Latinos consisting of CBT for panic disorder (PD), asthma education, differentiation between panic and asthma symptoms, and heart rate variability biofeedback. An RCT compared CBPT to music and relaxation therapy (MRT), which included listening to relaxing music and paced breathing at resting respiration rates. Fifty-three Latino (primarily Puerto Rican) adults with asthma and PD were randomly assigned to CBPT or MRT for 8 weekly sessions. Both groups showed improvements in PD severity, asthma control, and several other anxiety and asthma outcome measures from baseline to post-treatment and 3-month follow-up. CBPT showed an advantage over MRT for improvement in adherence to inhaled corticosteroids. Improvements in PD severity were mediated by anxiety sensitivity in CBPT and by depression in MRT, although earlier levels of these mediators did not predict subsequent improvements. Attrition was high (40%) in both groups, albeit comparable to CBT studies targeting anxiety in Latinos. Additional strategies are needed to improve retention in this high-risk population. Both CBPT and MRT may be efficacious interventions for comorbid asthma-PD, and CBPT may offer additional benefits for improving medication adherence.

    Although neuronal studies have shown that audiovisual integration is regulated by temporal factors, there is still little knowledge about the impact of temporal factors on audiovisual integration in older adults. To clarify how stimulus onset asynchrony (SOA) between auditory and visual stimuli modulates age-related audiovisual integration, 20 younger adults (21-24 years) and 20 older adults (61-80 years) were instructed to perform an auditory or visual stimuli discrimination experiment. The results showed that in younger adults, audiovisual integration was altered from an enhancement (AV, A ± 50 V) to a depression (A ± 150 V). In older adults, the alterative pattern was similar to that for younger adults with the expansion of SOA; however, older adults showed significantly delayed onset for the time-window-of-integration and peak latency in all conditions, which further demonstrated that audiovisual integration was delayed more severely with the expansion of SOA, especially in the peak latency for V-preceded-A conditions in older adults. Our study suggested that audiovisual facilitative integration occurs only within a certain SOA range (e.g., -50 to 50 ms) in both younger and older adults. Moreover, our results confirm that the response for older adults was slowed and provided empirical evidence that integration ability is much more sensitive to the temporal alignment of audiovisual stimuli in older adults.

    Glaucoma is the third-leading cause of blindness in the world, affecting >13.5 million people. Adult-onset primary open-angle glaucoma (POAG) is the most common form of glaucoma in the United States. We present a family in which adult-onset POAG is inherited as an autosomal dominant trait. Twelve affected family members were identified from 44 at-risk individuals. The disease-causing gene was mapped to chromosome 3q21-24, with analysis of recombinant haplotypes suggesting a total inclusion region of 11.1 cM between markers D3S3637 and D3S1744. This is the first report of mapping of an adult-onset POAG gene to chromosome 3q, gene symbol GLC1C. PMID:9012402

    2013-01-01

    BACKGROUND AND METHODS: We estimated the prevalence of self-reported asthma in adult Indians and examined several risk factors influencing disease prevalence. Analysis is based on 99 574 women and 56 742 men aged 20–49 years included in India’s third National Family Health Survey, 2005–2006. Multiple logistic regression analysis was used to estimate the prevalence odds ratios for asthma, adjusting for various risk factors. RESULTS: The prevalence of self-reported asthma was 1.8% (95%CI 1.6–2.0) among men and 1.9% (95%CI 1.8–2.0) among women, with higher rates in rural than in urban areas and marked geographic differences. After adjustment for known asthma risk factors, women were 1.2 times more likely to have asthma than men. Daily/weekly consumption of milk/milk products, green leafy vegetables and fruits were associated with a lower asthma risk, whereas consumption of chicken/meat, a lower body mass index (BMI; <16 kg/m2, OR 2.08, 95%CI 1.73–2.50) as well as a higher BMI (>30 kg/m2, OR 1.67, 95%CI 1.36–2.06), current tobacco smoking (OR 1.30, 95%CI 1.12–1.50) and ever use of alcohol (OR 1.21, 95%CI 1.05–1.39) were associated with an increased asthma risk. CONCLUSIONS: There are wide regional variations in the prevalence of asthma in India. With the exception of the findings for BMI, however, most of the associations of asthma with the risk factors are relatively weak and account for only a small proportion of cases. PMID:23317966

    BACKGROUND The gap in asthma prevalence, morbidity, and mortality is increasing in low-income racial/ethnic minority groups as compared with Caucasians. In order to address these disparities, alternative beliefs and behaviors need to be identified. OBJECTIVE To identify causal models of asthma and the context of conventional prescription versus complementary and alternative medicine (CAM) use in low-income African-American (AA) adults with severe asthma. DESIGN Qualitative analysis of 28 in-depth interviews. PARTICIPANTS Twenty-six women and 2 men, aged 21 to 48, who self-identified as being AA, low-income, and an inner-city resident. APPROACH Transcripts of semi-structured in-depth qualitative interviews were inductively analyzed using the constant comparison approach. RESULTS Sixty-four percent of participants held biologically correct causal models of asthma although 100% reported the use of at least 1 CAM for asthma. Biologically based therapies, humoral balance, and prayer were the most popular CAM. While most subjects trusted prescription asthma medicine, there was a preference for integration of CAM with conventional asthma treatment. Complementary and alternative medicine was considered natural, effective, and potentially curative. Sixty-three percent of participants reported nonadherence to conventional therapies in the 2 weeks before the research interview. Neither CAM nor nonmedical causal models altered most individuals (93%) willingness to use prescription medication. Three possibly dangerous CAM were identified. CONCLUSIONS Clinicians should be aware of patient-generated causal models of asthma and use of CAM in this population. Discussing patients' desire for an integrated approach to asthma management and involving social networks are 2 strategies that may enhance patient-provider partnerships and treatment fidelity.

    The Pollution Atmosphérique et Affections Respiratoires Chroniques (PAARC; Air Pollution and Chronic Respiratory Diseases) study provided the opportunity to examine the 25-yr mortality of 940 asthmatic adults drawn from a large population-based sample of 14,267 adults investigated during 1974-1976 in seven French cities. Vital statistics were collected in 2001 for the whole population. Multivariate survival analysis was used to assess exact survival rates in asthmatics and nonasthmatics taking relevant confounders into account. On average, the mortality rates obtained were 10.4 and 6.9 deaths 1,000 person-yrs-in asthmatics and nonasthmatics, respectively. On univariate analysis, asthma increased the relative risk (RR) of death by 1.48 (95% confidence interval (CI) 1.29-1.69). The association between asthma and death had an RR of 1.16 (95% CI 0.99-1.37) when age, sex, educational level, smoking habits, occupational exposure and forced expiratory volume in one second (FEV1) were taken into account. FEV1 was an important contributive factor causing increased risk of death in both smokers and nonsmokers. For instance, in asthmatics, the numbers of deaths due to respiratory disease and cancer appeared excessive. The present study suggests that asthmatics exhibit a higher risk of mortality.

    Adult-onset Still's disease is a rare disorder with potentially severe clinical features, including cardiac involvement. This systemic inflammatory disease of unknown origin should be considered in the differential diagnosis of pericarditis, with or without pericardial effusion. Cardiac tamponade is a very rare sequela that requires an invasive approach, such as percutaneous or surgical pericardial drainage, in addition to the usual conservative therapy. The authors describe a case of adult-onset Still's disease rendered more difficult by pericarditis and cardiac tamponade, and they briefly review the literature on this entity.

    Fever of unknown origin is often a diagnostic challenge. Here we present a case of 55-year-old woman with a history of a few months fever, progressing weakness and salmon-coloured, macular skin rash. The differential diagnosis included neoplasmatic conditions, infections and connective tissue disorders. Finally adult onset Still's disease was suspected. Glucocorticosteroid treatment was induced. During the therapy a central nervous system infection occurred, which was fatal for the patient. The presented clinical case shows that among many causes of fever of unknown origin, adult onset Still's disease should be taken into account.

    Background Chemoattractant receptor-homologous molecule expressed on T helper type 2 (Th2) cell (CRTh2) receptor antagonists is being investigated for asthma. Objectives The aim of this study was to assess the effects of the CRTh2 receptor antagonist, AZD1981 (with/without inhaled corticosteroids [ICSs]), on lung function and asthma control. Patients and methods Adults aged 18–60 years were enrolled in two randomized, placebo-controlled, parallel-group trials (protocol number: D9830C00003 [study 1, n=209] and protocol number: D9830C00004 [study 2, n=510]). In study 1, patients with stable asthma (forced expiratory volume in 1 second [FEV1]: 65%−110%) were withdrawn from ICS (<400 µg/d) and randomized to AZD1981 1,000 mg twice daily (bid) or placebo. In study 2, patients with uncontrolled asthma (FEV1: 40%−85%) despite ICS therapy (≥500 µg/d) were randomized to 50 mg, 400 mg, or 1,000 mg bid AZD1981 or placebo. The primary efficacy variable for both trials was the change in morning peak expiratory flow after 4 weeks of treatment. Secondary variables included Asthma Control Questionnaire (ACQ-5) scores, FEV1 assessments, safety, and tolerability. In study 2, efficacy was also assessed according to atopic status. Results Following 4 weeks of treatment, there was a nonsignificant increase in morning peak expiratory flow on AZD1981 1,000 mg bid (9.5 L/min vs placebo, P=0.086 [study 1] and 12 L/min vs placebo, P=0.16 [study 2]). In study 2, all doses of AZD1981 provided significant improvements in ACQ-5 scores (0.26–0.3 units vs placebo, P=0.010–0.022); however, there was no dose–response relationship. Improved ACQ-5 scores and FEV1 were observed in the majority of atopic patients treated with AZD1981. AZD1981 was well tolerated across treatment groups. Conclusion Further research may be warranted in atopic patients to fully evaluate the clinical efficacy of AZD1981. PMID:27621597

    1996-01-01

    Because of the significant differences between the juvenile and adult forms of open-angle glaucoma, especially with regard to inheritance, prevalence, severity, and age of onset, we read with interest the recent publication by Morissette et al., describing a pedigree with a phenotype that overlaps the distinctive features of juvenile-onset open-angle glaucoma (JOAG) and adult-onset primary open-angle glaucoma (usually abbreviated as POAG or COAG). These authors conclude that a gene mapped to human chromosome 1q21-q31 (GLC1A) can be responsible for both juvenile and adult forms of open-angle glaucoma. The implications of such a result could be extremely important, in light of the high prevalence of the adult form of the disease. However, while the data presented in this report suggest that variable expressivity of the GLC1A gene may lead to a broader range of onset for this form of juvenile glaucoma, these data do not identify the GLC1A gene as an important cause of POAG. To prevent misleading interpretations of this and similar studies, we wish to clarify the distinction between the juvenile and adult forms of open-angle glaucoma. 8 refs.

    Xanthelasmoid or pseudoxanthomatous mastocytosis is an extremely rare variant of diffuse cutaneous mastocytosis. Herein, we describe an adult male with cutaneous mastocytosis showing multiple widespread yellowish ovoid papules like eruptive xanthoma. A 60-year-old male visited our outpatient clinic with a 1-year history of generalized yellowish, ovoid, and skin color papular eruption located on the trunk, groin, extremities, with the modest pruritus. Vital signs were stable, and Darier's sign was negative. No other subjective and objective signs were detected during the examination. No abnormality was detected in his diagnostic laboratory tests. Skin biopsy was taken, and histopathologic examination revealed proliferation of mast cells with ovoid and spindle nuclei with distinct cytoplasm borders around the capillaries, which was compatible with mastocytosis. Antihistamine was prescribed for pruritus control which was successful, but eruptions were persistent, and even 1-year phototherapy was not useful. PMID:27512209

    Advances in the management of children with chronic liver disease have enabled many to survive into adulthood with or without their native livers, so that the most common of these conditions are becoming increasingly common in adult hepatology practice. Because the aetiologies of chronic liver disease in children may vary significantly from those in adulthood, adults with paediatric-onset chronic liver disease may often present with clinical manifestations unfamiliar to their adulthood physician. Transition of medical care to adult practice requires that the adulthood medical staff (primary physicians and subspecialists) have a comprehensive knowledge of childhood liver disease and their implications, and of the differences in caring for these patients. Pending still unavailable Scientific Society guidelines, this article examines causes, presentation modes, evaluation, management, and complications of the main paediatric-onset chronic liver diseases, and discusses key issues to aid in planning a program of transition from paediatric to adult patients.

    The purpose of the research was to determine if an adult asthma self-management program could significantly improve psychological outcomes for participants. Small groups of adults met for 2 hours for 7 consecutive weeks. Intervention techniques included interactive discussions, problem solving, social support, and a behavior modification procedure. The behavior modification procedure consisted of homework assignments in which participants were asked to self-monitor and record asthma-specific behaviors (peak expiratory flow monitoring, avoidance/removal of asthma triggers, and controller medication adherence) and general lifestyle behaviors (drinking water, washing hands, and exercising). Paired sample t tests indicated statistically significant improvements for the outcomes of quality of life, depression, and self-efficacy. Significant increases were found in knowledge and behaviors, such as peak-flow monitoring and frequency of daily exercise. These results provide initial evidence that our program was effective, although the small sample size and lack of control group indicate the need for further research.

    Background Several metals have been reported to be associated with childhood asthma. However, the results on relationships between metals and risk of childhood asthma are inconclusive, and the research on adult asthma in the Chinese general population is rare. Objectives To investigate potential associations between levels of urinary metals and adult asthma. Methods A case-control study of 551 adult asthma cases and 551 gender- and age-matched controls was conducted in Wuhan, China. Demographic information was obtained, and lung function was assessed. The urinary concentrations of 22 metals were measured by inductively coupled plasma mass spectrometry. Results After adjusting for other metalsand other covariates, urinary cadmium, molybdenum, chromium, copper, uranium and selenium were positively associated with asthma, with odds ratios (95% CI) of 1.69 (1.00, 2.85), 3.76 (2.30, 6.16), 4.89 (3.04, 7.89), 6.06 (3.27, 11.21), 6.99 (4.37, 11.19) and 9.17 (4.16, 20.21), respectively. By contrast, urinary lead, barium, iron, zinc, nickel, manganese and rubidium were negatively associated with asthma, with odds ratios (95% CI) of 0.48 (0.29, 0.80), 0.44 (0.27, 0.71), 0.41 (0.26, 0.64), 0.40 (0.24, 0.66), 0.30 (0.22, 0.41), 0.23 (0.14, 0.39) and 0.07 (0.03, 0.15), respectively. When comparing urinary metals in different subgroups of cases with those in matched controls, the associations of above 13 metals with asthma prevalence were nearly the same. Conclusions Our results suggested that asthma prevalence in the Chinese adults was positively associated with urinary chromium, chromium, selenium, molybdenum, cadmium, and uranium, and negatively associated with urinary manganese, iron, nickel, zinc, rubidium, barium and lead. Additional research with larger populations in different regions is required to support our findings. PMID:27191859

    The adult onset Still's disease is a rare inflammatory pathology of unknown pathogeny. The clinical features are variable. The diagnosis is difficult since exclusion of infectious, systemic and tumoral pathologies should be done. The articular complications are frequent and can be revelatory of this pathology. The articular prognosis depends on the diagnosis delay and the treatment efficiency. Our study aims to analyze different aspects of articular manifestations complicating adult onset Still disease to define epidemiological, clinical and evolving characteristics of these complications. It was a cross-sectional study concerning 18 cases of adult onset Still disease diagnosed from 1990 to 2014 in the internal medicine A department of Charles Nicolle Hospital in Tunis, meeting Yamaguchi criteria. We identified clinical, radiological, evolving and therapeutic profile of the articular manifestations occurred in these patients. There were 11 women and 7 men. The average age was 27 years. The arthralgias were reported in all cases; while, the arthritis interested thirteen patients. A hand deformation was found in four patients. A wrist ankylosis was noted in one case and a flexion elbow in one patient. The Standard articular radiographs were normal in ten cases. The treatment associated essentially non-steroidal anti-inflammatory and/or corticosteroids and/or methotrexate. Concerning the evolving profile, the monocyclic form was present in 25% of the cases, the intermittent form in 40% and the chronic articular form in 35% of our patients. The adult onset Still's disease is rare and heterogeneous. The articular disturbances are frequent and have various outcomes.

    Most inflammatory bowel diseases (IBDs) are classic complex disorders represented by common alleles. Here we aimed to define the genetic architecture of pediatric and adult-onset IBDs for the Polish population. A total of 1495 patients were recruited, including 761 patients with Crohn’s disease (CD; 424 pediatric), 734 patients with ulcerative colitis (UC; 390 pediatric), and 934 healthy controls. Allelotyping employed a pooled-DNA genome-wide association study (GWAS) and was validated by individual genotyping. Whole exome sequencing (WES) was performed on 44 IBD patients diagnosed before 6 years of age, 45 patients diagnosed after 40 years of age, and 18 healthy controls. Altogether, out of 88 selected SNPs, 31 SNPs were replicated for association with IBD. A novel BRD2 (rs1049526) association reached significance of P = 5.2 × 10−11 and odds ratio (OR) = 2.43. Twenty SNPs were shared between pediatric and adult patients; 1 and 7 were unique to adult-onset and pediatric-onset IBD, respectively. WES identified numerous rare and potentially deleterious variants in IBD-associated or innate immunity-associated genes. Deleterious alleles in both groups were over-represented among rare variants in affected children. Our GWAS revealed differences in the polygenic architecture of pediatric- and adult-onset IBD. A significant accumulation of rare and deleterious variants in affected children suggests a contribution by yet unexplained genetic components. PMID:28008999

    The use of physical punishment for children is associated with poor psychological and behavioral outcomes, but the causal pathway is controversial, and the effects on later physical health unknown. We conducted a cross-sectional survey of asthma, cancer, and cardiac patients (150 in each category, 75 male) recruited from outpatient clinics and 250 healthy controls (125 male). All participants were 40-60 years old and citizens of Saudi Arabia, where the use of beating and insults is an acceptable parenting style. Demographic data and recalled frequency of beatings and insults as a child were assessed on an 8-point scale. Beating and insults were highly correlated (ρ = 0.846). Propensity score matching was used to control for demographic differences between the disease and healthy groups. After controlling for differences, more frequent beating (once or more per month) and insults were associated with a significantly increased risk for cancer (RR = 1.7), cardiac disease (RR = 1.3) and asthma (RR = 1.6), with evidence of increased risk for cancer and asthma with beating frequency of once every 6 months or more. Our results show that a threatening parenting style of beating and insults is associated with increased risk for somatic disease, possibly because this form of parenting induces stress. Our findings are consistent with previous research showing that child abuse and other early life stressors adversely affect adult somatic health, but provide evidence that the pathogenic effects occur also with chronic minor stress. A stress-inducing parenting style, even when normative, has long term adverse health consequences.

    Objective To examine childhood-onset disease as a predictor of mortality in a cohort of adult patients with systemic lupus erythematosus (SLE). Methods Data were derived from the University of California Lupus Outcomes Study, a longitudinal cohort of 957 adult subjects with SLE that includes 98 subjects with childhood-onset SLE. Baseline and follow-up data were obtained via telephone interviews conducted between 2002-2007. The number of deaths during 5 years of follow-up was determined and standardized mortality ratios (SMRs) for the cohort, and across age groups, were calculated. Kaplan-Meier life table analysis was used to compare mortality rates between childhood (defined as SLE diagnosis <18 years) and adult-onset SLE. Multivariate Cox proportional hazard models were used to determine predictors of mortality. Results During the median follow-up period of 48 months, 72 deaths (7.5% of subjects) occurred, including 9 (12.5%) among those with childhood-onset SLE. The overall SMR was 2.5 (CI 2.0-3.2). In Kaplan-Meier survival analysis, after adjusting for age, childhood-onset subjects were at increased risk for mortality throughout the follow-up period (p<0.0001). In a multivariate model adjusting for age, disease duration and other covariates, childhood-onset SLE was independently associated with an increased mortality risk (hazard ratio [HR]: 3.1; 95% confidence interval [CI]: 1.3-7.3), as was low socioeconomic status measured by education (HR: 1.9; 95% CI 1.1-3.2) and end stage renal disease (HR: 2.1; 95% CI 1.1-4.0). Conclusion Childhood-onset SLE was a strong predictor of mortality in this cohort. Interventions are needed to prevent early mortality in this population. PMID:20235215

    The aim of this review was to evaluate the clinical effectiveness of fractional exhaled nitric oxide (FeNO) measured in a clinical setting for the management of asthma in adults. 13 electronic databases were searched and studies were selected against predefined inclusion criteria. Quality assessment was conducted using QUADAS-2. Class effect meta-analyses were performed. Six studies were included. Despite high levels of heterogeneity in multiple study characteristics, exploratory class effect meta-analyses were conducted. Four studies reported a wider definition of exacerbation rates (major or severe exacerbation) with a pooled rate ratio of 0.80 (95% CI 0.63–1.02). Two studies reported rates of severe exacerbations (requiring oral corticosteroid use) with a pooled rate ratio of 0.89 (95% CI 0.43–1.72). Inhaled corticosteroid use was reported by four studies, with a pooled standardised mean difference of −0.24 (95% CI −0.56–0.07). No statistically significant differences for health-related quality of life or asthma control were found. FeNO guided management showed no statistically significant benefit in terms of severe exacerbations or inhaled corticosteroid use, but showed a statistically significant reduction in exacerbations of any severity. However, further research is warranted to clearly define which management protocols (including cut-off points) offer best efficacy and which patient groups would benefit the most. PMID:26846832

    Vitamin D deficiency is common in children with asthma, and it associates with poor asthma control, reduced forced expiratory volume in one second (FEV1) and increased requirement for inhaled corticosteroids (ICS). Cross-sectional studies investigating the prevalence, determinants and clinical correlates of vitamin D deficiency in adults with asthma are lacking. We conducted a multi-centre cross-sectional study in 297 adults with a medical record diagnosis of ICS-treated asthma living in London, UK. Details of potential environmental determinants of vitamin D status, asthma control and medication use were collected by questionnaire; blood samples were taken for analysis of serum 25(OH)D concentration and DNA extraction, and participants underwent measurement of weight, height and fractional exhaled nitric oxide concentration (FeNO), spirometry and sputum induction for determination of lower airway eosinophil counts (n=35 sub-group). Thirty-five single nucleotide polymorphisms (SNP) in 11 vitamin D pathway genes (DBP, DHCR7, RXRA, CYP2R1, CYP27B1, CYP24A1, CYP3A4 CYP27A1, LRP2, CUBN, VDR) were typed using Taqman allelic discrimination assays. Linear regression was used to identify environmental and genetic factors independently associated with serum 25(OH)D concentration, and to determine whether vitamin D status was independently associated with Asthma Control Test (ACT) score, ICS dose, FeNO, forced vital capacity (FVC), FEV1 or lower airway eosinophilia. Mean serum 25(OH)D concentration was 50.6nmol/L (SD 24.9); 162/297 (54.5%) participants were vitamin D deficient (serum 25(OH)D concentration <50nmol/L). Lower vitamin D status was associated with higher body mass index (P=0.014), non-White ethnicity (P=0.036), unemployment (P for trend=0.012), lack of vitamin D supplement use (P<0.001), sampling in Winter or Spring (P for trend <0.001) and lack of a recent sunny holiday abroad (P=0.030), but not with potential genetic determinants. Vitamin D status was not found

    Glaucoma is the third-leading cause of blindness in the world, affecting >13.5 million people. Adult-on-set primary open-angle glaucoma (POAG) is the most common form of glaucoma in the United States. We present a family in which adult-onset POAG is inherited as an autosomal dominant trait. Twelve affected family members were identified from 44 at-risk individuals. The disease-causing gene was mapped to chromosome 3q21-24, with analysis of recombinant haplotypes suggesting a total inclusion region of 11.1 cM between markers D3S3637 and D3S1744. This is the first report of mapping of an adult-onset POAG gene to chromosome 3q, gene symbol GLC1C. 57 refs., 3 figs., 3 tabs.

    OBJECTIVE Adult-onset hydrocephalus is not commonly discussed in the literature, especially regarding its demographic distribution. In contrast to pediatric hydrocephalus, which is related to a primary CSF pathway defect, its development in adults is often secondary to other pathologies. In this study, the authors investigated the epidemiology of adult-onset hydrocephalus as it pertains to different etiologies and in reference to age, sex, and race distributions. METHODS The authors retrospectively reviewed the clinical notes of 2001 patients with adult-onset hydrocephalus who presented to Louisiana State University Health Sciences Center within a 25-year span. Significant differences between the groups were analyzed by a chi-square test; p < 0.05 was considered significant. RESULTS The overall mean (± SEM) incidence of adult hydrocephalus in this population was 77 ± 30 per year, with a significant increase in incidence in the past decade (55 ± 3 [1990-2003] vs 102 ± 6 [2004-2015]; p < 0.0001). Hydrocephalus in a majority of the patients had a vascular etiology (45.5%) or was a result of a tumor (30.2%). The incidence of hydrocephalus in different age groups varied according to various pathologies. The incidence was significantly higher in males with normal-pressure hydrocephalus (p = 0.03) or head injury (p = 0.01) and higher in females with pseudotumor cerebri (p < 0.0001). In addition, the overall incidence of hydrocephalus was significantly higher in Caucasian patients (p = 0.0002) than in those of any other race. CONCLUSIONS Knowledge of the demographic variations in adult-onset hydrocephalus is helpful in achieving better risk stratification and better managing the disease in patients. For general applicability, these results should be validated in a large-scale meta-analysis based on a national population database.

    Mutations in the NPHS1 gene cause congenital nephrotic syndrome of the Finnish type presenting before the first 3 months of life. Recently, NPHS1 mutations have also been identified in childhood-onset steroid-resistant nephrotic syndrome and milder courses of disease, but their role in adults with focal segmental glomerulosclerosis remains unknown. Here we developed an in silico scoring matrix to evaluate the pathogenicity of amino-acid substitutions using the biophysical and biochemical difference between wild-type and mutant amino acid, the evolutionary conservation of the amino-acid residue in orthologs, and defined domains, with the addition of contextual information. Mutation analysis was performed in 97 patients from 89 unrelated families, of which 52 presented with steroid-resistant nephrotic syndrome after 18 years of age. Compound heterozygous or homozygous NPHS1 mutations were identified in five familial and seven sporadic cases, including one patient 27 years old at onset of the disease. Substitutions were classified as 'severe' or 'mild' using this in silico approach. Our results suggest an earlier onset of the disease in patients with two 'severe' mutations compared to patients with at least one 'mild' mutation. The finding of mutations in a patient with adult-onset focal segmental glomerulosclerosis indicates that NPHS1 analysis could be considered in patients with later onset of the disease.

    The adult-onset Alexander disease (AOAD) dramatically differs from the early onset AD with respect to clinical and neuroradiological findings. Herein we report the detailed clinical and neuroradiological findings of a Turkish family with AOAD. In all three cases, magnetic resonance imaging revealed marked atrophy of the mesencephalon, bulbus, and cervical spinal cord accompanied with signal abnormalities in the same regions along with supratentorial white matter. Basal ganglia were affected in two cases. Molecular genetic analysis revealed heterozygous mutation in the 8th exon of the glial fibrillary acidic protein gene M451I (c.1245G>A), leading to the diagnosis of AOAD in all cases. PMID:28360791

    We present the case of a 23-year-old man with fever of unknown origin, who developed acute liver failure 2 months after symptom onset, requiring an urgent liver transplantation. The diagnosis of adult-onset Still's disease was established after the reappearance of symptoms after transplantation, and high doses of corticosteroids were used to control disease activity. Subsequently, given the impossibility of tapering the steroid dose, interleukin-1 receptor blocking treatment was started with satisfactory outcome. We also review the published literature.

    Asthma in the United States has become an important public health issue, with many physicians, regulators, and scientists elsewhere expressing concern that criterion air pollutants have contributed to a rising tide of asthma cases and symptoms. This paper studies recent associations (from 2008 to 2012) between self-reported asthma experiences and potential predictors, including age, sex, income, education, smoking, and county-level average annual ambient concentrations of ozone (O3) and fine particulate matter (PM2.5) levels recorded by the U.S. Environmental Protection Agency, for adults 50 years old or older for whom survey data are available from the Centers for Disease Control and Prevention (CDC) Behavioral Risk Factor Surveillance System (BRFSS). We also examine associations between these variables and self-reported heart attack and stroke experience; all three health outcomes are positively associated with each other. Young divorced women with low incomes are at greatest risk of asthma, especially if they are ever-smokers. Income is an important confounder of other relations. For example, in logistic regression modeling, PM2.5 is positively associated (p<0.06) with both stroke risk and heart attack risk when these are regressed only against PM2.5, sex, age, and ever-smoking status, but not when they are regressed against these variables and income. In this data set, PM2.5 is significantly negatively associated with asthma risk in regression models, with a 10μg/m(3) decrease in PM2.5 corresponding to about a 6% increase in the probability of asthma, possibly because of confounding by smoking, which is negatively associated with PM2.5 and positively associated with asthma risk. A variety of non-parametric methods are used to quantify these associations and to explore potential causal interpretations.

    Glycogen storage disease type IV (GSD IV) is a rare autosomal recessive disorder caused by deficiency of the glycogen-branching enzyme (GBE). The diagnostic hallmark of the disease is the accumulation of a poorly branched form of glycogen known as polyglucosan (PG). The disease is clinically heterogeneous, with variable tissue involvement and age at onset. Complete loss of enzyme activity is lethal in utero or in infancy and affects primarily the muscle and the liver. However, residual enzyme activity as low as 5–20% leads to juvenile or adult onset of a disorder that primarily affects the central and peripheral nervous system and muscles and in the latter is termed adult polyglucosan body disease (APBD). Here, we describe a mouse model of GSD IV that reflects this spectrum of disease. Homologous recombination was used to knock in the most common GBE1 mutation p.Y329S c.986A > C found in APBD patients of Ashkenazi Jewish decent. Mice homozygous for this allele (Gbe1ys/ys) exhibit a phenotype similar to APBD, with widespread accumulation of PG. Adult mice exhibit progressive neuromuscular dysfunction and die prematurely. While the onset of symptoms is limited to adult mice, PG accumulates in tissues of newborn mice but is initially absent from the cerebral cortex and heart muscle. Thus, PG is well tolerated in most tissues, but the eventual accumulation in neurons and their axons causes neuropathy that leads to hind limb spasticity and premature death. This mouse model mimics the pathology and pathophysiologic features of human adult-onset branching enzyme deficiency. PMID:26385640

    The decrease in the number of children living on traditional farms in France during early childhood and changes in diet could both play a role in the increase in asthma prevalence over the last decades. This study aimed to assess 1) the association of farming lifestyle in childhood and asthma, and 2) whether diet in adulthood modifies the association between farming lifestyle in childhood and adult-onset asthma. In the French Etude Epidemiologique des Femmes de la Mutuelle Générale de l'Education Nationale (E3N) study (54,018 females; age 43-68 yrs), three indicators of farming lifestyle were defined: one using individual data (having farmer parents) and two using ecological data (born in a rural area and exposure to cattle). All farming lifestyle indicators were related to childhood- (<16 yrs) and adult-onset asthma (OR (95% CI) values for farmer parents were 0.54 (0.42-0.70) and 0.72 (0.62-0.84), respectively), and to diet in adulthood, in particular to high fruit and low wine intakes. The association between farmer parents and adult-onset asthma was not modified by diet in adulthood. Results extend previous observations in younger cohorts on the protective role of contact with livestock and farming lifestyle on asthma, in particular during childhood.

    This study provides data on the sources of asthma diagnoses in the adult Bangladeshi population in urban and rural settings. The paper also reports the prevalence of self-reported asthma diagnoses and associated socio-demographic factors. A cross-sectional study was conducted in three communities: two rural settings and one urban setting, with a total sample size of 32,665 subjects. Pre-existing surveillance data provided individual socio-demographic factors. Provider categories were based on previous research describing provider plurality in Bangladesh. Descriptive statistics, univariate regression and multivariate regression analyses were performed. Bachelor of Medicine, Bachelor of Surgery (MBBS) generalists provided the largest proportion of diagnoses in both urban (54.6%) and rural (42.4%) sites. The largest proportion of non-MBBS-trained healthcare workers providing diagnoses of asthma was spiritual healers (13.3%) in the urban settings and village doctors (42.4%) in rural settings. The overall prevalence of self-reported asthma diagnoses was 5.0% in the urban population and 3.5% in the rural population. The results highlight the importance of non-MBBS doctors in serving the healthcare needs of the Bangladeshi population. This study reveals a higher prevalence of self-reported asthma diagnoses in the urban setting than in rural ones, which is consistent with international literature on the topic.

    Introduction. Vitamin D deficiency has been linked to an increased risk of asthma exacerbations. Objective. This study aimed to compare vitamin D status during the period of severe asthma exacerbations and investigate if vitamin D supplementation improves asthma control. Methods. A total of 47 asthmatic patients and 40 healthy subjects participated in this study. Serum 25-hydroxyvitamin D (25(OH)D), asthma control test (ACT) score, and % predicted peak expiratory flow rate were evaluated in the period with and without severe asthma exacerbations. After that, we provided vitamin D2 supplements to the patients with low vitamin D levels for 3 months. Results. At the period of asthma exacerbation, the prevalence of vitamin D deficiency and insufficiency was 38.29% and 34.04%. There was no significant difference in the levels of serum 25(OH)D with and without asthma exacerbations but the levels were significantly higher in the healthy group. Serum 25(OH)D levels significantly correlated with ACT score. Moreover, vitamin D2 supplementation improved asthma control in uncontrolled asthma group. Conclusions. Hypovitaminosis D was common in asthmatic patients but was not the leading cause of asthma exacerbations. Serum 25(OH)D levels correlated with the ability to control asthma. Improving vitamin D status might be a benefit in uncontrolled asthmatic patients. PMID:27974898

    The substantial majority of patients with asthma can expect minimal breakthrough symptoms on standard doses of inhaled corticosteroids with or without additional add-on therapies. SIMPLES is a structured primary care approach to the review of a person with uncontrolled asthma which encompasses patient education monitoring, lifestyle and pharmacological management and addressing support needs which will achieve control in most patients. The small group of patients presenting with persistent asthma symptoms despite being prescribed high levels of treatment are often referred to as having 'difficult asthma'. Some will have difficult, 'therapy resistant' asthma, some will have psychosocial problems which make it difficult for them to achieve asthma control and some may prove to have an alternative diagnosis driving their symptoms. A few patients will benefit from referral to a 'difficult asthma' clinic. The SIMPLES approach, aligned with close co-operation between primary and specialist care, can identify this patient group, avoid inappropriate escalation of treatment, and streamline clinical assessment and management.

    Adult-onset Still's disease is a rare and difficult to diagnose multisystemic disorder considered as a multigenic autoinflammatory syndrome. Its immunopathogenesis seems to be at the crossroads between inflammasomopathies and hemophagocytic lymphohistiocytosis, the most severe manifestation of the disease. According to recent insights in the pathophysiology and thanks to cohort studies and therapeutic trials, two phenotypes of adult-onset Still's disease may be distinguished: a systemic pattern, initially highly symptomatic and with a higher risk to exhibit life-threatening complications such as reactive hemophagocytic lymphohistiocytosis, where interleukin-1 blockade seems to be very effective, a chronic articular pattern, more indolent with arthritis in the foreground and less severe systemic manifestations, which would threat functional outcome and where interleukin-6 blockade seems to be more effective. This review focuses on these data.

    Adult-onset Still's disease is a rare disorder, which creates difficulties in making a proper diagnosis. Ambiguous symptoms and results of auxiliary tests, lack of unequivocal diagnostic tests and the need to exclude other causes of the disease are major problems in clinical practice. A case of a 22-year-old woman with dominated recurrent fever, significantly elevated inflammation markers and arthritis is presented. Based on clinical signs after exclusion of infection, hematological and other reasons, the patient was diagnosed with adult-onset Still's disease. Standard treatment, with high doses of glucocorticoids and a disease-modifying drug, was applied, without the anticipated effects. The diagnostic tests were conducted again due to the lack of clinical improvement, increase of inflammatory markers and unusual response to treatment. A new symptom of significance, i.e. mediastinal lymphadenopathy, was found. After the histopathological examination of lymph nodes, Hodgkin's disease was diagnosed and targeted therapy for hematological malignancy was applied. PMID:27407236

    To assess the influence of diabetes mellitus on bone metabolism, we measured skeletal mass in the forearms of 35 patients with juvenile diabetes on insulin and 101 stable patients with adult-onset diabetes, on diet alone, insulin, or oral hypoglycemic agents. There was a significant loss of bone mass in both juvenile and adult-onset diabetes (P less than 0.01) as compared to controls matched for age and sex. The decrease was already present in patients with diabetes of less than five years' duration. Bone loss and duration of the diabetes did not correlate; the greatest decrease in bone mass was observed in the patients receiving oral agents. These data are consistent with the hypothesis that the loss of skeletal tissue in diabetes reflects the underlying disease since it occurs early and is not related to severity as evidenced by the need for insulin, to duration, or to treatment with insulin or diet alone.

    The endocrine disruptor vinclozolin has previously been shown to promote epigenetic transgenerational inheritance of adult onset disease in the rat. The current study was designed to investigate the transgenerational actions of vinclozolin on the mouse. Transient exposure of the F0 generation gestating female during gonadal sex determination promoted transgenerational adult onset disease in F3 generation male and female mice, including spermatogenic cell defects, testicular abnormalities, prostate abnormalities, kidney abnormalities and polycystic ovarian disease. Pathology analysis demonstrated 75% of the vinclozolin lineage animals developed disease with 34% having two or more different disease states. Interestingly, the vinclozolin induced transgenerational disease was observed in the outbred CD-1 strain, but not the inbred 129 mouse strain. Analysis of the F3 generation sperm epigenome identified differential DNA methylation regions that can potentially be utilized as epigenetic biomarkers for transgenerational exposure and disease.

  12. How does dementia onset in parents influence unmarried adult children's wealth.

    PubMed

    2016-03-01

    There is a growing concern that long-term care (LTC) needs of older adults lead to negative financial consequences for their family members. This paper examines whether the onset of dementia in parents influences wealth change among unmarried adult children regardless of their status as informal caregivers. Longitudinal data from seven waves (1998-2010) of the Health and Retirement Study (1540 person-wave observations) are used to analyze this question. Unconditional quantile regressions demonstrate that as a result of parental dementia diagnosis, unmarried adult children have lower wealth accumulation above the median of the wealth change distribution. These effects are more pronounced for unmarried adult children without siblings. Further, this response is observed to persist in the subsequent period as well. Both losses in labor income and nursing home expenditures may play a role in leading to wealth declines.

    Dystonia is characterized by the presence of involuntary muscle contractions that cause abnormal movements and posture. Adult onset focal dystonia include cervical dystonia, blepharospasm, arm dystonia and laryngeal dystonia. Besides motor manifestations, patients with focal dystonia frequently also display non-motor signs and symptoms. In this paper, we review the evidence of sensory and psychiatric disturbances in adult patients with focal dystonia. Clinical studies and neurophysiological investigations consistently show that the sensory system is involved in dystonia. Several studies have also demonstrated that neuropsychiatric disorders, particularly depression and anxiety, are more frequent in patients with focal dystonia, whereas data on obsessive compulsive disorders are more contrasting.

    Environmental compounds can promote epigenetic transgenerational inheritance of adult-onset disease in subsequent generations following ancestral exposure during fetal gonadal sex determination. The current study examined the ability of dioxin (2,3,7,8-tetrachlorodibenzo[p]dioxin, TCDD) to promote epigenetic transgenerational inheritance of disease and DNA methylation epimutations in sperm. Gestating F0 generation females were exposed to dioxin during fetal day 8 to 14 and adult-onset disease was evaluated in F1 and F3 generation rats. The incidences of total disease and multiple disease increased in F1 and F3 generations. Prostate disease, ovarian primordial follicle loss and polycystic ovary disease were increased in F1 generation dioxin lineage. Kidney disease in males, pubertal abnormalities in females, ovarian primordial follicle loss and polycystic ovary disease were increased in F3 generation dioxin lineage animals. Analysis of the F3 generation sperm epigenome identified 50 differentially DNA methylated regions (DMR) in gene promoters. These DMR provide potential epigenetic biomarkers for transgenerational disease and ancestral environmental exposures. Observations demonstrate dioxin exposure of a gestating female promotes epigenetic transgenerational inheritance of adult onset disease and sperm epimutations.

    Context No consensus exists for adjusting inhaled corticosteroid therapy in patients with asthma. Approaches include adjustment at outpatient visits guided by physician assessment of asthma control (symptoms, rescue therapy, pulmonary function), based on exhaled nitric oxide, or on a day-to-day basis guided by symptoms. Objective To determine if adjustment of inhaled corticosteroid therapy based on exhaled nitric oxide or day-to-day symptoms is superior to guideline-informed, physician assessment–based adjustment in preventing treatment failure in adults with mild to moderate asthma. Design, Setting, and Participants A randomized, parallel, 3-group, placebo-controlled, multiply-blinded trial of 342 adults with mild to moderate asthma controlled by low-dose inhaled corticosteroid therapy (n=114 assigned to physician assessment–based adjustment [101 completed], n=115 to biomarker-based [exhaled nitric oxide] adjustment [92 completed], and n=113 to symptom-based adjustment [97 completed]), the Best Adjustment Strategy for Asthma in the Long Term (BASALT) trial was conducted by the Asthma Clinical Research Network at 10 academic medical centers in the United States for 9 months between June 2007 and July 2010. Interventions For physician assessment–based adjustment and biomarker-based (exhaled nitric oxide) adjustment, the dose of inhaled corticosteroids was adjusted every 6 weeks; for symptom-based adjustment, inhaled corticosteroids were taken with each albuterol rescue use. Main Outcome Measure The primary outcome was time to treatment failure. Results There were no significant differences in time to treatment failure. The 9-month Kaplan-Meier failure rates were 22% (97.5% CI, 14%-33%; 24 events) for physician assessment–based adjustment, 20% (97.5% CI, 13%-30%; 21 events) for biomarker-based adjustment, and 15% (97.5% CI, 9%-25%; 16 events) for symptom-based adjustment.

    In order to increase inhaled corticosteroid (ICS) use and to reduce hospitalization, emergency department visits and ultimately the economic burden of asthma, "Korean Asthma Management Guideline for Adults 2007" was developed. To assess the guideline effects on physician's ICS prescription for asthma, we conducted segmented regression and multilevel logistic regression using National Health Insurance claims database of outpatient visits from 2003 to 2010. We set each quarter of a year as a time unit and compared ICS prescription between before and after guideline dissemination. A total of 624,309 quarterly visits for asthma was observed. The ICS prescription rate before and after guideline dissemination was 13.3% and 16.4% respectively (P < 0.001). In the segmented regression, there was no significant guideline effect on overall ICS prescription rate. In multilevel logistic regression analyses, the effect of guideline on overall ICS prescription was not significant (odds ratio, 1.03; 95% CI, 1.00-1.06). In subgroup analysis, ICS prescription increased in secondary care hospitals (odds ratio, 1.15; 95% CI, 1.02-1.30) and in general hospitals (odds ratio, 1.10; 95% CI, 1.04-1.16). However, in primary clinics, which covered 81.7% of asthma cases, there was no significant change (odds ratio, 0.98; 95% CI, 0.94-1.02). From the in-depth interview, we could identify that the reimbursement criteria of the Health Insurance Review and Assessment Service and patient's preference for oral drug were barriers for the ICS prescription. The domestic asthma clinical guideline have no significant effect on ICS prescription, especially in primary clinics.

    This pilot study aims to provide effect size confidence intervals, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy of Dietary Approaches to Stop Hypertension (DASH) as adjunct therapy to standard care for adults with uncontrolled asthma. The DASH diet encompasses foods (e.g., fresh fruit, vegetables, and nuts) and antioxidant nutrients (e.g., vitamins A, C, E, and zinc) with potential benefits for persons with asthma, but it is unknown whether the whole diet is beneficial. Participants (n = 90) will be randomized to receive usual care alone or combined with a DASH intervention consisting of 8 group and 3 individual sessions during the first 3 months, followed by at least monthly phone consultations for another 3 months. Follow-up assessments will occur at 3 and 6 months. The primary outcome measure is the 7-item Juniper Asthma Control Questionnaire, a validated composite measure of daytime and nocturnal symptoms, activity limitations, rescue medication use, and percentage predicted forced expiratory volume in 1 second. We will explore changes in inflammatory markers important to asthma pathophysiology (e.g., fractional exhaled nitric oxide) and their potential to mediate the intervention effect on disease control. We will also conduct pre-specified subgroup analyses by genotype (e.g., polymorphisms on the glutathione S transferase gene) and phenotype (e.g., atopy, obesity). By evaluating a dietary pattern approach to improving asthma control, this study could advance the evidence base for refining clinical guidelines and public health recommendations regarding the role of dietary modifications in asthma management.

    Many non-communicable diseases (NCDs) are largely preventable via behaviour change and healthy lifestyle, which may be best established during childhood. This study sought insights into Chinese new immigrant mothers' perceptions about adult-onset NCDs prevention during childhood. Twenty-three semi-structured interviews were carried out with new immigrant mothers from mainland China who had at least one child aged 14 years or younger living in Hong Kong. Interviews were audio taped, transcribed and analysed using a Grounded Theory approach. The present study identified three major themes: perceived causes of adult NCDs, beliefs about NCDs prevention and everyday health information practices. Unhealthy lifestyle, contaminated food and environment pollution were perceived as the primary causes of adult NCDs. Less than half of the participants recognized that parents had responsibility for helping children establish healthy behaviours from an early age to prevent diseases in later life. Most participants expressed helplessness about chronic diseases prevention due to lack of knowledge of prevention, being perceived as beyond individual control. Many participants experienced barriers to seeking health information, the most common sources of health information being interpersonal conversation and television. Participants' everyday information practice was passive and generally lacked awareness regarding early prevention of adult-onset NCDs. Updated understanding of this issue has notable implications for future health promotion interventions.

    Background Respiratory symptoms are commonly used to assess the impact of patient-centered interventions. Objective At the request of National Institutes of Health (NIH) institutes and other federal agencies, an expert group was convened to propose which measurements of asthma symptoms should be used as a standardized measure in future clinical research studies. Methods Asthma symptom instruments were classified as daily diaries (prospectively recording symptoms between research visits) or retrospective questionnaires (completed at research visits). We conducted a systematic search in PubMed and a search for articles that cited key studies describing development of instruments. We classified outcome instruments as either core (required in future studies), supplemental (used according to study aims and standardized), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop in March 2010 and finalized in September 2011. Results Four instruments (3 daily diaries, 1 for adults and 2 for children; and 1 retrospective questionnaire for adults) were identified. Minimal clinically important differences have not been established for these instruments, and validation studies were only conducted in a limited number of patient populations. Validity of existing instruments may not be generalizable across racial-ethnic or other subgroups. Conclusions An evaluation of symptoms should be a core asthma outcome measure in clinical research. However, available instruments have limitations that preclude selection of a core instrument. The working group participants propose validation studies in diverse populations, comparisons of diaries versus retrospective questionnaires, and evaluations of symptom assessment alone versus composite scores of asthma control.

    Background: Although long-chain ω-3 (n−3) PUFAs (LCω3PUFAs) have been linked to the prevention of some inflammatory disorders, little is known about the association between these fatty acids and incidence of asthma. Objective: The objective was to prospectively investigate the association between LCω3PUFAs and fish intake and incidence of asthma among American young adults. Design: A 20-y follow-up longitudinal analysis was conducted in a biracial cohort of 4162 Americans, aged 18–30 y, with a history of asthma at baseline in 1985. Diet was assessed by a validated interviewer-administered quantitative food-frequency questionnaire at the examinations in 1985, 1992, and 2005. Incident self-reported asthma was defined as having a physician diagnosis of asthma and/or the use of asthma medications between 1985 and 2005. Results: During the 20-y follow-up, 446 incident cases of asthma were identified. LCω3PUFA intake was significantly inversely associated with incidence of asthma after adjustment for sociodemographic, major lifestyle, and dietary confounders. The multivariable-adjusted HR for the highest quintile of LCω3PUFA intake as compared with the lowest quintile was 0.46 (95% CI: 0.33, 0.64; P-trend < 0.01). However, a higher frequency of nonfried fish consumption was not significantly associated with the risk of asthma. DHA showed a greater inverse association than did EPA. The association between LCω3PUFAs and incident asthma was not appreciably modified by sex, race, BMI, smoking status, or atopic status. Conclusion: This study showed that intakes of LCω3PUFAs are inversely longitudinally associated with the incidence of asthma in American young adults. PMID:23193002

    Environmental compounds including fungicides, plastics, pesticides, dioxin and hydrocarbons can promote the epigenetic transgenerational inheritance of adult-onset disease in future generation progeny following ancestral exposure during the critical period of fetal gonadal sex determination. This study examined the actions of the pesticide methoxychlor to promote the epigenetic transgenerational inheritance of adult-onset disease and associated differential DNA methylation regions (i.e. epimutations) in sperm. Gestating F0 generation female rats were transiently exposed to methoxychlor during fetal gonadal development (gestation days 8 to 14) and then adult-onset disease was evaluated in adult F1 and F3 (great-grand offspring) generation progeny for control (vehicle exposed) and methoxychlor lineage offspring. There were increases in the incidence of kidney disease, ovary disease, and obesity in the methoxychlor lineage animals. In females and males the incidence of disease increased in both the F1 and the F3 generations and the incidence of multiple disease increased in the F3 generation. There was increased disease incidence in F4 generation reverse outcross (female) offspring indicating disease transmission was primarily transmitted through the female germline. Analysis of the F3 generation sperm epigenome of the methoxychlor lineage males identified differentially DNA methylated regions (DMR) termed epimutations in a genome-wide gene promoters analysis. These epimutations were found to be methoxychlor exposure specific in comparison with other exposure specific sperm epimutation signatures. Observations indicate that the pesticide methoxychlor has the potential to promote the epigenetic transgenerational inheritance of disease and the sperm epimutations appear to provide exposure specific epigenetic biomarkers for transgenerational disease and ancestral environmental exposures.

    Enterobacteriaceae is a leading pathogen of community-onset bacteremia. This study aims to establish a predictive scoring algorithm to identify adults with community-onset Enterobacteriaceae bacteremia who are at risk for abscesses. Of the total 1262 adults, 152 (12.0%) with abscess occurrence were noted. The 6 risk factors significantly associated with abscess occurrence-liver cirrhosis, diabetes mellitus, thrombocytopenia and high C-reactive protein (>100 mg/L) at bacteremic onset, delayed defervescence, and bacteremia-causing Klebsiella pneumoniae-were each assigned +1 point to form the scoring algorithm. In contrast, the elderly, fatal comorbidity (McCabe classification), and bacteremia-causing Escherichia coli were each assigned -1 point, owing to their negative associations with abscess occurrence. Using the proposed scoring algorithm, a cut-off value of +1 yielded a high sensitivity (85.5%) and an acceptable specificity (60.4%). Although the proposed predictive model needs further validation, this simple scoring algorithm may be useful for the early identification of abscesses by clinicians.

    Objectives. We examined neighborhood-level foreclosure rates and their association with onset of depressive symptoms in older adults. Methods. We linked data from the National Social Life, Health, and Aging Project (2005–2006 and 2010–2011 waves), a longitudinal, nationally representative survey, to data on zip code–level foreclosure rates, and predicted the onset of depressive symptoms using logit-linked regression. Results. Multiple stages of the foreclosure process predicted the onset of depressive symptoms, with adjustment for demographic characteristics and changes in household assets, neighborhood poverty, and visible neighborhood disorder. A large increase in the number of notices of default (odds ratio [OR] = 1.75; 95% confidence interval [CI] = 1.14, 2.67) and properties returning to ownership by the bank (OR = 1.62; 95% CI = 1.06, 2.47) were associated with depressive symptoms. A large increase in properties going to auction was suggestive of such an association (OR = 1.45; 95% CI = 0.96, 2.19). Age, fewer years of education, and functional limitations also were predictive. Conclusions. Increases in neighborhood-level foreclosure represent an important risk factor for depression in older adults. These results accord with previous studies suggesting that the effects of economic crises are typically first experienced through deficits in emotional well-being. PMID:24446830

    Ankylosing spondylitis (AS) has 2 main modes of onset: juvenile-onset AS (JoAS) and adult-onset AS (AoAS). It is not known whether JoAS is a subtype of AS, or AS modulated by early age of onset and longer disease duration. We performed a systematic review of the literature, identifying 12 articles and 1 abstract directly comparing JoAS and AoAS cohorts, with observational study design. Patients with JoAS appear to have more peripheral joint involvement both clinically and radiographically (especially knees and ankles) and more root joint involvement (hips and shoulders); they are more likely to proceed to hip arthroplasty and often initially present with peripheral rather than axial symptoms. Patients with AoAS appear to have more axial symptoms and radiographic disease, particularly in the lumbar spine, and worse axial metrology. In terms of other characteristics, more evidence is needed to confidently state whether JoAS and AoAS are different.

    Background High serum uric acid (sUA) is an indicator of oxidative stress and is linked to tissue hypoxia in asthma. The objective of this case series was to investigate the prognostic role of sUA in patients with acute asthma exacerbations and the link between sUA and spirometric lung tests. Patients and methods This cross-sectional observational study included 120 patients with acute asthma exacerbations and 120 controls, categorized according to peak expiratory flow rate into moderate, and severe and life-threatening asthma. On admission, a detailed history was obtained and investigations were carried out regarding oxygen saturation (SaO2), arterial blood gas, spirometry, sUA, number of asthma exacerbations, smoking status, history of previous hospitalization, intensive care unit admission, and mechanical ventilation. Results The current study revealed higher sUA in asthmatic patients compared with healthy subjects and in severe asthma patients compared with moderate asthma patients (P<0.001). A positive correlation of sUA with asthma severity, number of asthma exacerbations and smoking index (r=0.6, 0.42 and 0.29, respectively, P<0.001) and a negative correlation of sUA with SaO2, partial pressure of arterial oxygen (PaO2), percent predicted forced vital capacity, percent predicted forced expiratory volume (FEV%) and peak expiratory flow rate percent of predicted (PEFR%; r=−0.48, −0.29, −0.44, −0.44 and −0.66, respectively, P<0.001) were observed. Degree of asthma severity, number of asthma exacerbations, and smoking index were significant predictors of high sUA (R2=0.43, P<0.001) in multiple linear regression model 1. SaO2 and PEFR% were significant predictors of high uric acid (R2=0.50, P<0.001) in model 2. The sensitivity and specificity of sUA in predicting severity of asthma at the cutoff point of 6.3 mg/dL were 80% and 90%, respectively. The odds ratios of sUA, number of asthma exacerbations, and asthma duration were 5.4, 1.95 and 1

    Inadequate attention given to the management of asthma and ways of improving bronchial asthma control could be an important factor for the rising morbidity and mortality from asthma despite major advances in our understanding of the disease process. There is a paucity of data concerning the challenges faced in the management of asthma in Africa. This review was aimed at highlighting the challenges facing asthma management and to discuss various strategies in improving asthma control in Nigeria. Data were sourced from PubMed, Medline, African Journals Online, Google Scholar, SCOPUS, and by reviewing the references of relevant literature. Additional articles were obtained via communications with colleagues and reviewing the Abstract Books of Nigeria Thoracic Society Annual Scientific Conference from 2005 to 2012. The data search was up-to-date as of December 31, 2012. Challenges in asthma management were found during diagnosis, treatment, and follow-up. There are wide variations in diagnostic criteria for bronchial asthma and lack of standard diagnostic equipment leading to under or misdiagnosis. Treatment challenges include poor communication gap between the health-care providers and the patients, a high-cost and unavailability of essential asthma medications. Poor technique uses for medication devices, especially the inhalational drugs and Lack of National/hospital protocol or guidelines for treating asthma. Several challenges affect asthma management in developing countries, which borders on poverty, inadequate resources, weak health systems, and poor infrastructure. Efforts should be made to address these challenges by the Nigerian government, Nigerian Thoracic Society, pharmaceutical industries, and the health-care workers in general.

    Background Acrolein is an air toxic and highly potent respiratory irritant. There is little epidemiology available, but US EPA estimates that outdoor acrolein is responsible for about 75 percent of non-cancer respiratory health effects attributable to air toxics in the United States, based on the Agency's 2005 NATA (National-Scale Air Toxics Assessment) and acrolein's comparatively potent inhalation reference concentration of 0.02 µg/m3. Objectives Assess the association between estimated outdoor acrolein exposure and asthma attack reported by a representative cross-sectional sample of the adult United States population. Methods NATA 2005 chronic outdoor acrolein exposure estimates at the census tract were linked with residences oif adults (≥18 years old) in the NHIS (National Health Interview Survey) 2000 – 2009 (n = 271,348 subjects). A sample-weighted logistic regression model characterized the association between the prevalence of reporting at least one asthma attack in the 12 months prior to survey interview and quintiles of exposure to outdoor acrolein, controlling for potential confounders. Results In the highest quintile of outdoor acrolein exposure (0.05 – 0.46 µg/m3), there was a marginally significant increase in the asthma attack pOR (prevalence-odds ratio [95% CI]  = 1.08 [0.98∶1.19]) relative to the lowest quintile. The highest quintile was also associated with a marginally significant increase in prevalence-odds (1.13 [0.98∶1.29]) in a model limited to never smokers (n = 153,820). Conclusions Chronic exposure to outdoor acrolein of 0.05 – 0.46 µg/m3 appears to increase the prevalence-odds of having at least one asthma attack in the previous year by 8 percent in a representative cross-sectional sample of the adult United States population.

    Asthma is a chronic inflammatory airways disorder mainly characterized by heterogeneity. In the more severe forms, a discordance often exists between symptoms and inflammation. Difficulty in managing asthma derives partly from the multiple phenotypes existing and our inability to recognize them. The use of non-invasive, with main representative the fraction of exhaled nitric oxide, or semi-invasive techniques such as induced sputum are effective tools that can help us to guide asthma treatment. In the latest years, several serum biomarkers related to asthmatic inflammation have been used for the better recognition of asthma sub-phenotypes to achieve optimization of therapy and disease outcome. In patients with mild-moderate asthma, as well as patients with more severe asthma, the use of blood eosinophils revealed an acceptable accuracy for the prediction of airway eosinophilia indicating that in future studies may facilitate both individualized treatment and management of asthma. None of the above techniques have been incorporated in clinical practice although sputum eosinophils can be used in patients with severe asthma particularly in specialized centers with great experience. Of great interest are blood eosinophils since current data support their role either as tool for treatment selections or/and as a biomarker of airway eosinophilia.

    Adult onset Still's disease (AOSD) is a rare systemic inflammatory disease of unknown etiology and pathogenesis that presents in 5 to 10% of patients as fever of unknown origin (FUO) accompanied by systemic manifestations. We report an interesting case of a 33-year-old African-American male who presented with one-month duration of FUO along with skin rash, sore throat, and arthralgia. After extensive workup, potential differential diagnoses were ruled out and the patient was diagnosed with AOSD based on the Yamaguchi criteria. The case history, incidence, pathogenesis, clinical manifestations, differential diagnoses, diagnostic workup, treatment modalities, and prognosis of AOSD are discussed in this case report.

Piriform sinus carcinoma with PS is extremely rare. We here report a case of piriform sinus carcinoma accompanied by PS that was initially misdiagnosed as adult onset Still's disease and describe our diagnosis and treatment. One lesson we have drawn from the experience of this misdiagnosis is that PS symptoms may manifest before the primary tumor is evident and complicate the diagnostic process.

    A 54-year-old woman presented to a foot centre with a chief symptom of cramping in her toes, which, she believed, was of a secondary cause originating from a bunion. She was treated conservatively; however, she returned a month later as the symptoms had progressed to painful cramping of toes, toe-curling and instability while walking, due to involuntary movement of her toes. It was believed that the patient presented with a rare case of primary adult onset focal foot dystonia. This case report explains dystonia further in detail and delves into the different treatment and management options available today, including the unique orthopaedic intervention provided for this patient.

    A 63-year-old female with no significant past medical history was presented with a 5-day history of progressive opsoclonus-myoclonus, headaches, and fevers. Her workup was significant only for positive West-Nile Virus serum serologies. She received a 2-day course of intravenous immunoglobulin (IvIG). At an 8-week follow up, she had a complete neurological remission. Adult-onset opsoclonus-myoclonus syndrome is a rare condition for which paraneoplastic and infectious causes have been attributed. To our knowledge, this is the first case reported of opsoclonus-myoclonus secondary to West-Nile Virus treated with intravenous immunoglobulin monotherapy.

    A 56-year-old female with refractory adult-onset Still's disease presented with ocular herpes zoster infection during TCZ treatment. After three days of acyclovir treatment (5 mg/kg), she developed a severe headache and high fever. Viral DNA isolation and cerebral spinal fluid abnormalities led to a herpes zoster meningitis diagnosis. Her meningitis was cured by high doses of intravenous acyclovir (10 mg/kg for 14 days). To our knowledge, this is the first report of meningeal herpes zoster infection in rheumatic diseases under TCZ treatment. PMID:27092286

    Adult-onset Still disease (AOSD) is a systemic inflammatory disorder characterized clinically by high spiking fever, polyarthralgia/arthritis, a salmon-pink evanescent rash, predominantly neutrophilic leucocytosis, lymphadenopathy, liver dysfunction, and splenomegaly. Recently, a nonclassic, nonevanescent skin rash has been reported. We report a 27-year-old woman with AOSD showing persistent pruritic papular lesions. Histologically, dyskeratotic keratinocytes were seen in the upper epidermis. We describe this case in detail and review the previous literature. Nonclassic pruritic eruptions with characteristic dyskeratotic keratinocytes might provide an important clue for the diagnosis of AOSD.

    Health-related quality of life (HRQOL) provides information on patients' everyday physical, emotional, and social difficulties that traditional measurements of asthma severity (pulmonary function assessments and asthma symptom scores) may not reflect. Our objective is to evaluate the effect of ciclesonide (CIC) on HRQOL in a combined analysis of two identical, 12-week, multicenter, double-blind, parallel-group, placebo-controlled trials. Patients (N=1015) with mild-to-moderate asthma (aged >or=12 years; forced expiratory volume in 1 s 60-85% predicted at randomization after administration of single-blind placebo during baseline [5-28 days]) were randomized to receive placebo or CIC 80, 160, or 320 microg (ex-actuator) once daily. HRQOL was assessed using the Juniper Asthma Quality-of-Life Questionnaire (AQLQ). The overall AQLQ score and individual domain scores (activity limitation, symptoms, emotional function, and exposure to environmental stimuli) were recorded at baseline, week 4 and week 12. Statistically significant improvements (p<0.0001) in overall AQLQ scores were observed for all CIC groups versus placebo (CIC80, 0.50; CIC160, 0.61; CIC320, 0.69; placebo, 0.14) from baseline to week 12. Similar significant improvements were observed for all CIC groups in the four individual domain scores, except the CIC80 environmental stimuli domain score. A greater proportion of CIC-treated patients achieved a minimally important difference in overall AQLQ score (>or=0.5 improvement) by week 4, which was sustained through to week 12, compared with placebo (week 12: CIC80, 47.1%; CIC160, 50%; CIC320, 50.6%; placebo, 31%). In this combined analysis, once-daily CIC significantly improved HRQOL compared with placebo, in adults/adolescents with mild-to-moderate persistent asthma.

    OBJECTIVE--To ascertain the standard of care for hospital management of acute severe asthma in adults. DESIGN--Questionnaire based retrospective multicentre survey of case records. SETTING--36 hospitals (12 teaching and 24 district general hospitals) across England, Wales, and Scotland. PATIENTS--All patients admitted with acute severe asthma between 1 August and 30 September 1990 immediately before publication of national guidelines for asthma management. MAIN MEASURES--Main recommendations of guidelines for hospital management of acute severe asthma as performed by respiratory and non-respiratory physicians. RESULTS--766 patients (median age 41 (range 16-94) years) were studied; 465 (63%) were female and 448 (61%) had had previous admissions for asthma. Deficiencies were evident for each aspect of care studied, and respiratory physicians performed better than non-respiratory physicians. 429 (56%) patients had had their treatment increased in the two weeks preceding the admission but only 237 (31%) were prescribed oral steroids. Initially 661/766 (86%) patients had peak expiratory flow measured and recorded but only 534 (70%) ever had arterial blood gas tensions assessed. 65 (8%) patients received no steroid treatment in the first 24 hours after admission. Variability of peak expiratory flow was measured before discharge in 597/759 (78%) patients, of whom 334 (56%) achieved good control (variability < 25%). 47 (6%) patients were discharged without oral or inhaled steroids; 182/743 (24%) had no planned outpatient follow up and 114 failed to attend, leaving 447 (60%) seen in clinic within two months. Only 57/629 (8%) patients were recorded as having a written management plan. CONCLUSIONS--The hospital management of a significant minority of patients deviates from recommended national standards and some deviations are potentially serious. Overall, respiratory physicians provide significantly better care than non-respiratory physicians. PMID:10142032

    Still's disease and chronic recurrent multifocal osteomyelitis (CRMO) are febrile rheumatic diseases of unknown etiology, which predominantly affect children but can also have their initial manifestation in adults. Both can present as intermittent, relapsing episodes and are considered potential candidates within the expanding spectrum of autoinflammatory disorders, although no genetic abnormalities have been described for either of them. Here, we describe a man with an initial manifestation of abacterial multifocal osteitis at the age of 41. During a relapsing-remitting course of his illness, he increasingly developed symptoms of adult-onset Still's disease (AOSD), and the diagnosis was established according to the Yamaguchi criteria. When treated with anakinra, not only the acute symptoms disappeared promptly, but also the osteitis went into complete remission. This is to our knowledge the first description of a simultaneous occurrence of these two manifestations of autoinflammation in adulthood.

    A 51-year-old Chinese man presented with gaze-evoked nystagmus, impaired smooth pursuit and vestibular ocular reflex cancellation, and saccadic dysmetria, along with a family history suggestive of late-onset autosomal dominant parkinsonism. MRI revealed abnormalities of the medulla and cervical spinal cord typical of adult-onset Alexander disease, and genetic testing showed homozygosity for the p.D295N polymorphic allele in the gene encoding the glial fibrillary acidic protein. A review of the literature shows that ocular signs are frequent in adult-onset Alexander disease, most commonly gaze-evoked nystagmus, pendular nystagmus, and/or oculopalatal myoclonus, and less commonly ptosis, miosis, and saccadic dysmetria. These signs are consistent with the propensity of adult-onset Alexander disease to cause medullary abnormalities on neuroimaging.

    Adult onset leukodystrophy with neuroaxonal spheroids is an uncommon cause of dementia. Both hereditary (autosomal dominant) and sporadic cases have been described. A 41-year-old African woman presented with inappropriate behavior and personality change consistent with frontal lobe dysfunction. MRI demonstrated diffuse frontoparietal white matter signal abnormality and volume loss, as well as focal enhancing white matter lesions, while CT scan showed white matter calcifications. She had been gradually deteriorating over the last 5 years, diagnosed as having progressive demyelinating illness. She died of recurrent chest infections. There was no familial history. The brain showed prominent symmetrical white matter changes with greyish discolorization mainly affecting the frontal and parietal lobes, with less involvement of the temporal lobe and only mildly affecting the occipital white matter. Histology revealed deep white matter atrophy with many neuroaxonal spheroids labelled by neurofilament and β-amyloid precursor protein. In addition, scattered inactive demyelinating plaque-like lesions were found in the periventricular areas, brainstem and the cervical spinal cord. This case had typical features of an adult onset leukodystrophy with neuroaxonal spheroids. However, we also demonstrated demyelinating plaque-like lesions, which has not been previously described. The possibility of a demyelinating origin contributing to the changes may be considered in the pathogenesis of this condition.

    Objective: To identify the genetic defect for adult-onset primary lateral sclerosis (PLS) in a family with 5 patients. Methods: Whole-exome sequencing was performed to identify the shared genetic variants in 3 affected members in a PLS family with 5 affected individuals. Sanger sequencing was used for validation of the variants and for cosegregation analysis. Mitochondrial activity for both patients and unaffected siblings was measured using a SeaHorse metabolic analyzer. Results: Whole-exome sequencing and subsequent cosegregation analysis demonstrated that compound heterozygous missense variants L695P and I743T in SPG7 were the only mutations cosegregating with the disease in an autosomal recessive fashion in this family. The parents and siblings are genetically heterozygous and clinically unaffected. Functional studies suggested that the PLS-associated SPG7 mutants affect mitochondrial function when glucose is reduced. Conclusions: Compound heterozygote mutations in SPG7 are associated with adult-onset PLS, extending the spectrum of SPG7-linked neurologic diseases. Patients with the PLS phenotype should have genetic testing for paraplegin, especially when the condition is familial. PMID:27123479

    Adults who stutter (AWS) have demonstrated atypical coordination of motor and sensory regions during speech production. Yet little is known of the speech-motor network in AWS in the brief time window preceding audible speech onset. The purpose of the current study was to characterize neural oscillations in the speech-motor network during preparation for and execution of overt speech production in AWS using magnetoencephalography (MEG). Twelve AWS and 12 age-matched controls were presented with 220 words, each word embedded in a carrier phrase. Controls were presented with the same word list as their matched AWS participant. Neural oscillatory activity was localized using minimum-variance beamforming during two time periods of interest: speech preparation (prior to speech onset) and speech execution (following speech onset). Compared to controls, AWS showed stronger beta (15–25 Hz) suppression in the speech preparation stage, followed by stronger beta synchronization in the bilateral mouth motor cortex. AWS also recruited the right mouth motor cortex significantly earlier in the speech preparation stage compared to controls. Exaggerated motor preparation is discussed in the context of reduced coordination in the speech-motor network of AWS. It is further proposed that exaggerated beta synchronization may reflect a more strongly inhibited motor system that requires a stronger beta suppression to disengage prior to speech initiation. These novel findings highlight critical differences in the speech-motor network of AWS that occur prior to speech onset and emphasize the need to investigate further the speech-motor assembly in the stuttering population.

    Objective: To investigate the molecular basis of a Belgian family with autosomal recessive adult-onset neuronal ceroid lipofuscinosis (ANCL or Kufs disease [KD]) with pronounced frontal lobe involvement and to expand the findings to a cohort of unrelated Belgian patients with frontotemporal dementia (FTD). Methods: Genetic screening in the ANCL family and FTD cohort (n = 461) was performed using exome sequencing and targeted massive parallel resequencing. Results: We identified a homozygous mutation (p.Ile404Thr) in the Cathepsin F (CTSF) gene cosegregating in the ANCL family. No other mutations were found that could explain the disease in this family. All 4 affected sibs developed motor symptoms and early-onset dementia with prominent frontal features. Two of them evolved to akinetic mutism. Disease presentation showed marked phenotypic variation with the onset ranging from 26 to 50 years. Myoclonic epilepsy in one of the sibs was suggestive for KD type A, while epilepsy was not present in the other sibs who presented with clinical features of KD type B. In a Belgian cohort of unrelated patients with FTD, the same heterozygous p.Arg245His mutation was identified in 2 patients who shared a common haplotype. Conclusions: A homozygous CTSF mutation was identified in a recessive ANCL pedigree. In contrast to the previous associations of CTSF with KD type B, our findings suggest that CTSF genetic testing should also be considered in patients with KD type A as well as in early-onset dementia with prominent frontal lobe and motor symptoms.

    Dysplasia epiphysealis hemimelica (DEH), or Trevor’s disease, is an osteocartilaginous epiphyseal overgrowth typically occurring in children. The literature reports 6 adult cases and none describe recurrence requiring additional procedures. We present a new-onset proximal tibial DEH in an adult recurring approximately 3 years after open excision. A 39-year-old female presented with a history of right knee pain, swelling, and instability. Physical examination revealed a firm proximal tibial mass. Computed tomography (CT) imaging showed an exophytic, lobulated, sclerotic mass involving the anterolateral margin of the lateral tibial plateau. Magnetic resonance imaging was suggestive of an osteochondroma. The patient underwent curettage of the lesion due to its periarticular location. Histology revealed benign and reactive bone and cartilage consistent with periosteal chondroma. Two and a half years later, the patient presented with a firm, palpable mass larger than the initial lesion. CT revealed a lateral tibial plateau sclerotic mass consistent with recurrent intra-articular DEH. A complete excision was performed and histology showed sclerotic bone with overlying cartilage consistent with exostosis. DEH is a rare epiphyseal osteocartilaginous outgrowth frequently occurring in the long bones of children less than 8 years old. DEH resembles an osteochondroma due to its pediatric presentation and similar histologic appearance. Adult-onset cases comprise less than 1% of reported cases. Recurrence rate after surgical intervention is unknown. Only 1 such case, occurring in a child, has been described. Clinicians contemplating operative treatment for DEH should note the potential for recurrence and consider complete excision. A follow-up period of several years may be warranted to identify recurrent lesions. PMID:28144583

  11. Environmental Epigenetic of Asthma – An update

    PubMed Central

    Ho, Shuk-Mei

    2013-01-01

    Asthma, a chronic inflammatory disorder of the airway, is influenced by interplay between genetic and environmental factors now known to be mediated by epigenetics. Aberrant DNA methylation, altered histone modifications, specific microRNA expression, and other chromatin alterations orchestrate a complex early-life reprogramming of immune T cell response, dendritic cell function, macrophage activation, and a breach of airway epithelial barrier that dictates asthma risk and severity in later life. Adult-onset asthma is under analogous regulation. The sharp increase in asthma prevalence over the past two or three decades and the large variations among populations of similar racial/ethnic background but different environmental exposures favors a strong contribution of environmental factors. This review addresses the fundamental question of whether environmental influences on asthma risk, severity, and steroid resistance are partly due to differential epigenetic modulations. Current knowledge on epigenetic effects of tobacco smoke, microbial allergens, oxidants, airborne particulate matter, diesel exhaust particles, dietary methyl donors and other nutritional factors, and dust mites is discussed. Exciting findings have been generated by rapid technological advances and well-designed experimental and population studies. The discovery and validation of epigenetic biomarkers linked to exposure and/or asthma may lead to better epigenotyping of risk, prognosis, treatment prediction, and development of novel therapies.

    2005-01-01

    Background: Current guidelines recommend the use of a combination of inhaled ß2 agonists and anticholinergics, particularly for patients with acute severe or life threatening asthma in the emergency setting. However, this statement is based on a relatively small number of randomised controlled trials and related systematic reviews. A review was undertaken to incorporate the more recent evidence available about the effectiveness of treatment with a combination of ß2 agonists and anticholinergics compared with ß2 agonists alone in the treatment of acute asthma. Methods: A search was conducted of all randomised controlled trials published before April 2005. Results: Data from 32 randomised controlled trials (n = 3611 subjects) showed significant reductions in hospital admissions in both children (RR = 0.73; 95% CI 0.63 to 0.85, p = 0.0001) and adults (RR = 0.68; 95% CI 0.53 to 0.86, p = 0.002) treated with inhaled anticholinergic agents. Combined treatment also produced a significant increase in spirometric parameters 60–120 minutes after the last treatment in both children (SMD = –0.54; 95% CI –0.28 to –0.81, p = 0.0001) and adults (SMD = –0.36; 95% CI –0.23 to –0.49, p = 0.00001). Conclusions: This review strongly suggests that the addition of multiple doses of inhaled ipratropium bromide to ß2 agonists is indicated as the standard treatment in children, adolescents, and adults with moderate to severe exacerbations of asthma in the emergency setting.

    Alexander disease (AD) in its typical form is an infantile lethal leucodystrophy, characterized pathologically by Rosenthal fibre accumulation. Following the identification of glial fibrillary acidic protein (GFAP) gene as the causative gene, cases of adult-onset AD (AOAD) are being described with increasing frequency. AOAD has a different clinical and neuroradiological presentation with respect to early-onset AD, as abnormalities are mainly concentrated in the brainstem-spinal cord junction. We report detailed clinical and genetic data of 11 cases of AOAD, observed over a 4-year period, and a review of the previously reported 25 cases of genetically confirmed AOAD. In our series, onset occurred as late as age 62, and up to 71 in an affected deceased relative. Most cases appeared sporadic, but family history may be misleading. The most frequent symptoms were related to bulbar dysfunction-with dysarthria, dysphagia, dysphonia (seven patients)-, pyramidal involvement (seven patients) and cerebellar ataxia (seven patients). Four patients had palatal myoclonus. Sleep disorders were also observed (four cases). Bulbar symptoms, however, were infrequent at onset and two symptomatic patients had an almost pure pyramidal involvement. Two subjects were asymptomatic. Misdiagnosis at presentation was frequent and MRI was instrumental in suggesting the correct diagnosis by showing, in all cases, mild to severe atrophy of the medulla oblongata extending caudally to the cervical spinal cord. In ten patients, molecular studies revealed six novel missense mutations and three previously reported changes in GFAP. The last typical patient carried no definitely pathogenic mutation, but a missense variant (p.D157N), supposedly a rare polymorphism. Revision of the literature and the present series indicate that the clinical picture is not specific, but AOAD must be considered in patients of any age with lower brainstem signs. When present, palatal myoclonus is strongly suggestive

    A 17-year-old female patient was referred to the Infectious Diseases Ward because of fever lasting for 14 days. On admission to the hospital the patient was in a generally good state, without any abnormalities on physical examination. Laboratory investigation revealed elevated inflammatory markers. Diagnostic imaging comprising chest X-ray, abdominal ultrasonography, and echocardiography showed no abnormalities. During the hospitalization, there occurred episodes of fever with skin rash and musculoskeletal pain of the lower limbs. Procalcitonin concentrations continued to increase. C-reactive protein concentrations decreased during therapy, starting from 191 mg/l. On the 23rd day of the disease, edema of the feet, ankles, and knees appeared. On the basis of the clinical picture and after excluding other possible causes of fever, the patient was diagnosed with adult onset Still’s disease. The procalcitonin concentration was normalized after 5 days of steroid therapy. The patient was discharged under ambulatory rheumatologic supervision. PMID:27826176

    A 72-year-old man presented with consciousness disturbance. The results of brain magnetic resonance imaging and cerebrospinal fluid examination were normal, but triphasic waves were noted on electroencephalography. His plasma ammonia level was elevated due to which encephalopathy secondary to hyperammonemia was suspected. However, his liver function was normal, and no evidence of cirrhosis or portal-systemic shunt was noted. The patient's medical history revealed that he had a tendency to excessively consume pulse products since childhood, and an amino acid analysis showed elevation of citrulline and arginine levels. Thus, we diagnosed the patient with an extremely rare case of adult-onset type II citrullinemia, which was triggered by cessation of the intake of pulse foods (soybeans and peanuts) due to dental problems.

    A nine-year-old neutered female mixed breed dog presented for evaluation following a five-day history of lethargy, inappetence, weakness, abdominal distension and generalised muscle atrophy. Persistent vatrial standstill with a junctional rhythm was identified on electrocardiogram. Echocardiogram identified moderate dilation of all cardiac chambers and mild thickening of the mitral and tricuspid valves. Serology was negative for Neospora caninum and Toxoplasma gondii. Permanent pacemaker implantation was performed in addition to endomyocardial and skeletal muscle biopsies. Cryosections from the biceps femoris muscle showed numerous nemaline rod bodies while endomyocardial biopsies were possibly consistent with end-stage myocarditis. Rod bodies have rarely been reported in the veterinary literature. To the authors' knowledge, this is the first report of adult-onset nemaline rod myopathy and hypothyroidism with concurrent cardiac disease in a dog.

    Adult-onset Still’s disease (AOSD) – a multi-systemic inflammatory condition characterized by high fevers, polyarthritis, an evanescent rash, and pharyngitis – has been a challenging condition to diagnose expediently and treat effectively. Questions remain regarding the underlying pathophysiology and etiology of AOSD. Pathognomonic diagnostic tests and reliable biomarkers remain undiscovered. Over the past decade, important progress has been made. Diagnostic criteria employing glycosylated ferritin have improved specificity. More important, novel biologic therapies have offered important clues to AOSD’s underlying pathophysiology. Cytokine-specific biologic therapies have been instrumental in providing more effective treatment for disease refractory to conventional treatment. While IL-1 therapy has demonstrated efficacy in refractory disease, novel therapies targeting IL-6 and IL-18 show great promise and are currently under investigation. PMID:27843366

    Intradural spinal teratoma is a very rare tumour that can be associated with dysraphic defects. We report a case of adult-onset intradural spinal teratoma in the lumbar spine. The patient was a 54-year-old female who had chief complaints of a gait disturbance. X-rays showed an enlargement of the interpedicular distance at L3/L4 and spina bifida distal to L4. MRI showed a spindle-shaped tumour between L2 and L5. We performed laminotomy using an ultrasonic surgical knife. Pathological diagnosis of the resected tumour was matured teratoma. The diagnosis of matured teratoma was made because the tumour had no epithelium and a layered structure including prostate tissue, matured fat, cartilage and sweat gland.

    We encountered 6 rare cases of acute-onset unilateral psychogenic hearing loss in adults. All were women in their 20s and 30s. Three cases had severe hearing impairment characterized by hearing loss at every frequency; 2 cases had profound hearing impairment, and 1 case had low-frequency hearing impairment. Of the 6 cases, 3 had a history of hearing loss, and 1 had a history of psychogenic visual disturbance. All 6 cases were initially diagnosed as having idiopathic sudden sensorineural hearing loss; all subsequently received steroid therapy. Three cases were not diagnosed as being psychogenic in origin until otoacoustic emissions and auditory brain responses were performed. Although the presence of distinctive clinical features (age, gender, and past history) is important for suspecting psychogenic hearing loss, objective audiological tests such as otoacoustic emissions are essential for diagnosing some cases. Compared to the existing reports of similar cases, our cases had a poorer prognosis (only 2 cases were cured).

    Hemophagocytic Lymphystiocytosis is a rare and fatal complication of rheumatic diseases, particularly Adult Onset Still's Disease (AOSD). It may be precipitated with immunosuppressive drugs and with viral and bacterial infections. A diagnosis depends on a high index of suspicion associated to certain clinical manifestations (fever, rash, Splemomegaly, any cytology blood dyscrasia, hipertrigliceridemia, hiperfibrinogenemia, and others), as well as pathologic evidence of hemophagocitosis from bone marrow biopsy or tissue samples of affected organs. Therapy consists of high dose corticosteroids and immunosuppressive drugs. We present a 42 year old woman with AOSD in remission who developed HLH in spite of receiving therapy with high dose steroids and immunosuppressive drugs. She had 2 negative bone marrow aspirates. Evidence of Hemophagocytosis was detected in both bone marrow biopsies. Timely evaluation and recognition of the signs and symptoms of HLH is crucial for the prompt management and a decrease in the mortality associated with this disease.

    Genetic factors are of great importance in common adult-onset disorders such as atherosclerosis, cancer, and neuro-degenerative diseases. Advances in DNA technology now allow identification of persons at high-risk of developing some of these diseases. This advance is leading to predictive medicine. In some genetic disorders, such as those leading to atherosclerosis and cancer, identification of high-risk individuals allows intervention which alters the natural history of the disorder. In other diseases, for which there is no treatment, such as Huntington's disease, the application of this technology provides information that relieves uncertainty and may affect quality of life, but does not alter the course of the illness. General implementation of predictive testing programs awaits the results of pilot projects, which will demonstrate the needs, appropriate levels of support, and guidelines for delivery of such testing.

    Mutations in the solute carrier family 25 (SLC25A13) gene may result in neonatal intrahepatic cholestasis caused by citrin deficiency and/or adult-onset type II citrullinemia. These conditions are inherited in an autosomal recessive manner. The current case report describes a 43-year-old man who presented with sudden delirium and upper limb weakness. Upon admission, the patient was fully conscious and alert but later lost consciousness subsequent to a sudden convulsive seizure. Hyperammonemia was detected and analysis of the SLC25A13 gene identified an 851del4 mutation. Thus, the possibility of genetic disease should be considered as a potential cause of the symptoms of patients with altered states of consciousness, such as delirium and loss of consciousness, in cases where the cause of the disturbance is unknown.

    Abstract Background: Thymoma is a T cell neoplasm arising from the thymic epithelium that due to its immunological role, frequently undercover derangements of immunity such a tumors and autoimmune diseases. Methods: Herein, we report, to the best of our knowledge, the first description of an association between thymoma and adult onset Still disease (AOSD) in a 47-year-old man. The first one was occasionally detected 4 years later the diagnosis of AOSD, and surgically removed via right lateral thoracotomy. Histology confirmed an encapsulated thymic tumor (type AB sec. WHO-classification). Results: The AOSD was particularly resistant to the therapy, requiring a combination of immunosuppressant followed by anti-IL1R, that was the only steroids-sparing treatment capable to induce and maintain the remission. The differential diagnosis was particularly challenging because of the severe myasthenic-like symptoms that, with normal laboratory tests, were initially misinterpreted as fibromyalgia. The pathogenic link of this association could be a thymus escape of autoreactive T lymphocytes causing autoimmunity. Conclusion: Clinicians should be always include the possibility of a thymoma in the differential diagnosis of an unusual new onset of weakness and normal laboratories data, in particular once autoimmune disease is present in the medical history.

    Macrophage activation syndrome (MAS) is a potentially fatal complication of Adult-Onset Still's disease (Still's disease). Whereas an increasing body of evidence supports interleukin-1 (IL-1) blockade as a promising treatment for Still's disease, whether it is therapeutic for MAS associated with Still's disease remains unclear. We report a 34-year-old Caucasian man with one-decade history of TNF-blockade-responsive seronegative arthritis who presented with abrupt onset of fever, serositis, bicytopenia, splenomegaly, hepatitis, and disseminated intravascular coagulation. Striking hyperferritinemia was noted without evidence of infection, malignancy, or hemophagocytosis on bone marrow biopsy. NK cells were undetectable in the peripheral blood, whereas soluble IL-2 receptor was elevated. His multiorgan disease resolved in association with methylprednisolone pulse therapy, Anakinra, and a tapering course of prednisone. This case reinforces the notion that Still's disease is inherently poised to manifest MAS as one of the clinical phenotypes by shedding light on the role of IL-1 underlying both Still's disease and related MAS.

    Written autobiographies of 48 incarcerated adult male sexual offenders (22 rapists, 13 intrafamilial child molesters, and 13 extrafamilial child molesters) were used to generate retrospective self-report measures of their childhood maternal and paternal attachment, childhood sexual abuse experiences, and onset of masturbation. Contrary to expectation, the offenders as a combined group more often reported secure than they did insecure childhood maternal and paternal attachment. There were no differences between the three offender subgroups with respect to maternal attachment; however the rapists and the intrafamilial child molesters were more likely to report insecure paternal attachment than were the extrafamilial child molesters. There were no differences between these offender subgroups in the frequency with which childhood sexual abuse was reported. However, offenders with insecure paternal attachment were more likely to report having been sexually abused than were those with secure paternal attachment. Sexually abused offenders in turn reported earlier onset of masturbation than did those who were not sexually abused. These results are consistent with contemporary attachment models linking insecure childhood attachment to childhood sexual abuse, and with traditional conditioning models linking childhood sexual abuse, early masturbation, and sexual offending.

    Purpose: Skeletal muscle damage occurs following high-intensity or unaccustomed exercise; however, it is difficult to monitor damage to the respiratory muscles, particularly in humans. The aim of this study was to use clinical measures to investigate the presence of skeletal muscle damage in the inspiratory muscles. Methods: Ten healthy subjects underwent 60 minutes of voluntary inspiratory threshold loading (ITL) at 70% of maximal inspiratory pressure. Maximal inspiratory and expiratory mouth pressures, delayed onset muscle soreness on a visual analogue scale and plasma creatine kinase were measured prior to ITL, and at repeated time points after ITL (4, 24 and 48 hours post-ITL). Results: Delayed onset muscle soreness was present in all subjects 24 hours following ITL (intensity = 22 ± 6 mm; significantly higher than baseline p = 0.02). Muscle soreness was reported primarily in the anterior neck region, and was correlated to the amount of work done by the inspiratory muscles during ITL (r = 0.72, p = 0.02). However, no significant change was observed in maximal inspiratory or expiratory pressures or creatine kinase. Conclusions: These findings suggest that an intense bout of ITL results in muscle soreness primarily in the accessory muscles of inspiration, however, may be insufficient to cause significant muscle damage in healthy adults.

    We report the case of a 43-year-old woman presenting with nocturnal episodes of pain and screaming during sleep starting at age 30. There was no childhood or family history of parasomnia. The events had gradually become more frequent over the years, occurring in the first half of the night within 2 h of sleep onset. There were no triggers, and she had partial amnesia for the events. A diagnosis of adult-onset sleep terrors was made on clinical grounds and supported polysomnographically. Seizures and periodic limb movements were excluded as triggering factors. There was some mild sleep disordered breathing (predominantly non-desaturating hypopnea with a propensity for REM sleep of debatable significance). Imaging of the brain and spine and neurophysiological investigations ruled out lesions, entrapments, or neuropathies as possible causes of pain. Treatment (clonazepam, paroxetine, or gabapentin) was poorly tolerated and made no difference to the nocturnal episodes, while trazodone worsened them. This is the first report of hypnopompic psychic pain in association with a NREM parasomnia. We hypothesize that the pain may represent a sensory hallucination analogous to the more commonly recognized visual NREM parasomnia-associated hypnopompic visual hallucinations and that, as such, it may arise during arousal of the sensory neocortex as confabulatory response.

    OBJECTIVE The aim of this study was to investigate the presence and correlates of clinically relevant cognitive impairment in middle-aged adults with childhood-onset type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS During 2010–2013, 97 adults diagnosed with T1D and aged <18 years (age and duration 49 ± 7 and 41 ± 6 years, respectively; 51% female) and 138 similarly aged adults without T1D (age 49 ± 7 years; 55% female) completed extensive neuropsychological testing. Biomedical data on participants with T1D were collected periodically since 1986–1988. Cognitive impairment status was based on the number of test scores ≥1.5 SD worse than demographically appropriate published norms: none, mild (only one test), or clinically relevant (two or more tests). RESULTS The prevalence of clinically relevant cognitive impairment was five times higher among participants with than without T1D (28% vs. 5%; P < 0.0001), independent of education, age, or blood pressure. Effect sizes were large (Cohen d 0.6–0.9; P < 0.0001) for psychomotor speed and visuoconstruction tasks and were modest (d 0.3–0.6; P < 0.05) for measures of executive function. Among participants with T1D, prevalent cognitive impairment was related to 14-year average A1c >7.5% (58 mmol/mol) (odds ratio [OR] 3.0; P = 0.009), proliferative retinopathy (OR 2.8; P = 0.01), and distal symmetric polyneuropathy (OR 2.6; P = 0.03) measured 5 years earlier; higher BMI (OR 1.1; P = 0.03); and ankle-brachial index ≥1.3 (OR 4.2; P = 0.01) measured 20 years earlier, independent of education. CONCLUSIONS Clinically relevant cognitive impairment is highly prevalent among these middle-aged adults with childhood-onset T1D. In this aging cohort, chronic hyperglycemia and prevalent microvascular disease were associated with cognitive impairment, relationships shown previously in younger populations with T1D. Two additional potentially modifiable risk factors for T1D-related cognitive impairment, vascular health and BMI

    Objective: To comparatively assess the B-cell composition in blood and CSF of patients with pediatric-onset multiple sclerosis (pedMS) and adult-onset multiple sclerosis (adMS). Methods: In this cross-sectional study, we obtained blood and CSF samples from 25 patients with pedMS (8–18 years) and 40 patients with adMS (23–65 years) and blood specimens from 66 controls (1–55 years). By using multicolor flow cytometry, we identified naive, transitional, isotype class-switched memory, nonswitched memory, and double-negative memory B-cell subsets as well as plasmablasts (PB) and terminally differentiated plasma cells (PC). Flow cytometric data were compared to concentrations of B-cell-specific cytokines in serum and CSF as determined by ELISA. Results: Frequencies of circulating naive B-cells decreased with higher age in controls but not in patients with multiple sclerosis (MS). B-cell patterns in CSF differed between pedMS and adMS with an acute relapse: in pedMS-derived CSF samples, high frequencies of nonswitched memory B cells and PB were present, whereas class-switched memory B cells and PC dominated in the CSF of patients with adMS. In pedMS, PB were also elevated in the periphery. Accumulation of PB in the CSF correlated with high intrathecal CXCL-13 levels and augmented intrathecal synthesis of immunoglobulin G and immunoglobulin M. Conclusions: We demonstrate distinct changes in intrathecal B-cell homeostasis in patients with pedMS during active disease, which differ from those in adults by an expansion of plasmablasts in blood and CSF and similarly occur in prototypic autoantibody-driven autoimmune disorders. This emphasizes the particular importance of activated B-lymphocyte subsets for disease progression in the earliest clinical stages of MS. PMID:28053999

    A comparison of clinical features and adult outcome in adolescents with three types of psychotic disorders: schizophrenic (SPh), schizoaffective (SA) and bipolar with psychotic features (BPP). Subjects (n = 41) were finally diagnosed (DSM-IV criteria) with SPh (n = 17), SA (n = 11) or BPP (n = 13). Clinical evaluation took place at onset and at a 3-year follow-up in all 41, and at least after 5 years in 36 patients. Symptoms were rated on the basis of the Positive and Negative Syndrome Scale (PANSS), integrating items from the Brief Psychiatric Rating Scale (BPRS) and the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). The Children Global Assessment Scale (C-GAS) and the Global Assessment Scale (GAF) were used to evaluate global functioning. Significant differences in clinical features were found in the three diagnostic groups as regards several parameters, some present on one and not on other rating scales, underscoring the insufficiency of a single scale for accurate analysis of the features of a psychotic disorder. At onset, a comparison using the simple presence/absence of symptoms showed scant differences among groups, while differences emerged if symptom severity was included in the comparison. Functioning at 3- and 5-year follow-ups showed a significantly better outcome in the BPP group and more substantial deterioration, with similar evolution, in the SPh and SA groups. The integration of several rating scales differentiated between diagnostic groups more effectively. The similar adult functioning outcome in the SPh and SA groups showed how difficult it is to clearly separate these two disorders.

  13. Increased Insomnia Symptoms Predict the Onset of Back Pain among Employed Adults

    2014-01-01

    Background Back pain is among the most prevalent pain disorders causing chronic disability among adults, and insomnia is a common co-morbidity. However, whether insomnia precedes back pain or vice versa remains unclear. The current study tested the temporal association between insomnia and back pain. Methods A longitudinal design was used to investigate whether changes in insomnia over time predict the onset of back pain and vice versa. The study was conducted on a cohort of active healthy working adults (N = 2,131, 34% women) at three time points (T1, T2, and T3) over a period of 3.7 years (range = 2.2–5.12) years. Logistic regression analysis was used to test whether increased insomnia symptoms from T1 to T2 predicted the onset of new back pain. Ordinary least squares regression was used to test whether the existence of back pain at T2 predicted an increase in insomnia from T2 to T3. Results The results indicated that after controlling for socioeconomic variables, self-reported health, lifestyle behaviors, and anthropometrics, a T1–T2 increase in insomnia symptoms was associated with a 1.40-fold increased risk of back pain at T3 (OR = 1.40; 95% CI = 1.10–1.71). No support was found for reverse causation; i.e., that back pain predicts subsequent increase in insomnia. Conclusions Insomnia appears to be a risk factor in the development of back pain in healthy individuals. However, no evidence of reverse causation was found. PMID:25084165

    Severe asthma in children is characterized by sustained symptoms despite treatment with high doses of inhaled corticosteroids or oral corticosteroids. Children with severe asthma may fall into 2 categories, difficult-to-treat asthma or severe therapy-resistant asthma. Difficult-to-treat asthma is defined as poor control due to an incorrect diagnosis or comorbidities, or poor adherence due to adverse psychological or environmental factors. In contrast, treatment resistant is defined as difficult asthma despite management of these factors. It is increasingly recognized that severe asthma is a highly heterogeneous disorder associated with a number of clinical and inflammatory phenotypes that have been described in children with severe asthma. Guideline-based drug therapy of severe childhood asthma is based primarily on extrapolated data from adult studies. The recommendation is that children with severe asthma be treated with higher-dose inhaled or oral corticosteroids combined with long-acting β-agonists and other add-on therapies, such as antileukotrienes and methylxanthines. It is important to identify and address the influences that make asthma difficult to control, including reviewing the diagnosis and removing causal or aggravating factors. Better definition of the phenotypes and better targeting of therapy based upon individual patient phenotypes is likely to improve asthma treatment in the future.

    Objective Despite a prevailing assumption that adult ADHD is a childhood-onset neurodevelopmental disorder, no prospective-longitudinal study has described the childhoods of the adult-ADHD population. We report follow-back analyses of ADHD cases diagnosed in adulthood, alongside follow-forward analyses of ADHD cases diagnosed in childhood, in one cohort. Method Participants belonged to a representative birth cohort of 1,037 individuals born in Dunedin, New Zealand in 1972-73 and followed to age 38, with 95% retention. Symptoms of ADHD, associated clinical features, comorbid disorders, neuropsychological deficits, GWAS-derived polygenic risk, and life impairment indicators were assessed. Data sources were participants, parents, teachers, informants, neuropsychological testing, and administrative records. Adult ADHD diagnoses used DSM5 criteria, apart from onset-age and cross-setting corroboration, which were study outcomes. Results As expected, the childhood-ADHD group showed 6% prevalence, male excess, childhood comorbid disorders, neurocognitive deficits, polygenic risk, and, despite having outgrown their ADHD diagnosis, residual adult life impairment. As expected, the adult-ADHD group showed 3% prevalence, gender balance, adult substance dependence, adult life impairment, and treatment contact. Unexpectedly, the childhood-ADHD and adult-ADHD groups comprised virtually non-overlapping sets; 90% of adult-ADHD cases lacked a history of childhood ADHD. Also unexpectedly, the adult-ADHD group did not show tested neuropsychological deficits in childhood or adulthood, nor did they show polygenic risk for childhood ADHD. Conclusion Findings raise the possibility that adults presenting with the ADHD symptom picture may not have a childhood-onset neurodevelopmental disorder. If this finding is replicated, then the disorder's place in the classification system must be reconsidered, and research must investigate the etiology of adult ADHD. PMID:25998281

    Introduction While seasonal influenza vaccination is recommended for individuals with asthma, uptake in this population is low. We examined how self-rated health impacts reasons for not being immunized against influenza in Canadian adults with asthma, focusing on those who have never been immunized. Methods We pooled four cycles of the Canadian Community Health Survey (cycles 3.1(2005), 2007/08, 2009/10 and 2011/12), grouping individuals by whether their reasons for not having been vaccinated were perceptual or technical. We used a multivariable logistic regression model, adjusted for confounders, to quantify the relationship between self-rated health and their reported reasons for not vaccinating. Results Among the 9,836 respondents, 84.4% cited perceptual barriers as a reason for not being vaccinated. After adjusting for socio-demographic characteristics and province of residence, we determined that reporting perceptual barriers was associated with self-rated health status, with the adjusted odds ratios ranging from 1.42 (95%CI: 0.97, 2.09) to 2.64 (95%CI: 1.74, 3.99) for fair and excellent health versus poor health, respectively. Each increase in self-rated health category was associated with greater odds of citing a perceptual rather than technical barrier as a reason for non-vaccination. Discussion Self-reported health influences people’s perception of the need for influenza vaccination. Viewing the results through the lens of the precaution adoption process model suggests that personalizing communication around both the risk of influenza and the effectiveness of the vaccine may improve uptake amongst adults with asthma.

    A significant proportion of patients discharged from the emergency department (ED) with asthma exacerbations will relapse within 4 weeks. This systematic review summarises the evidence regarding relapses and factors associated with relapse in adult patients discharged from EDs after being treated for acute asthma. Following a registered protocol, comprehensive literature searches were conducted. Studies tracking outcomes for adults after ED management and discharge were included if they involved adjusted analyses. Methodological quality was assessed using the Newcastle–Ottawa Scale (NOS) and the Risk of Bias (RoB) Tool. Results were summarised using medians and IQRs or mean and SD, as appropriate. 178 articles underwent full-text review and 10 studies, of various methodologies, involving 32 923 patients were included. The majority of the studies were of high quality according to NOS and RoB Tool. Relapse proportions were 8±3%, 12±4% and 14±6% at 1, 2 and 4 weeks, respectively. Female sex was the most commonly reported and statistically significant factor associated with an increased risk of relapse within 4 weeks of ED discharge for acute asthma. Other factors significantly associated with relapse were past healthcare usage and previous inhaled corticosteroids (ICS) usage. A median of 17% of patients who are discharged from the ED will relapse within the first 4 weeks. Factors such as female sex, past healthcare usage and ICS use at presentation were commonly and significantly associated with relapse occurrence. Identifying patients with these features could provide clinicians with guidance during their ED discharge decision-making. PMID:28176972

    Older adults with asthma face numerous barriers to effective self-management and asthma control, and experience worse outcomes than younger asthmatics. Yet, there have been no controlled trials of interventions specifically designed to improve their care and outcomes. Through a multi-stakeholder collaboration (patients, academia, community-based organizations, a state department of health, and an advocacy organization) we developed a multi-component asthma self-management support intervention to address the myriad psychosocial, functional, health status, and cognitive barriers to effective asthma self-management in adults ages 60 and older. We are recruiting 425 New Yorkers in Manhattan and the Bronx for a pragmatic randomized controlled trial with 3 arms: the intervention delivered in primary care settings or in their home, or usual care. In the intervention, care coaches use a novel screening tool to identify the specific barriers to asthma control and self-management they experience. Once identified, the coach and patient choose from a menu of actions to address it. The intervention emphasizes efficiency, flexibility, shared decision making and goal setting, communication strategies appropriate for individuals with limited cognition and literacy skills, and ongoing reinforcement and support. Additionally, we introduced asthma-specific enhancements to the electronic health records of all participating clinical practices, including an asthma severity assessment, clinical decision support, and a patient-tailored asthma action plan. Patients will be followed for 12months and interviewed at baseline, 3, 6, and 12months and data on emergency department visits and hospitalizations will be obtained through the New York State Statewide Planning and Research Cooperative System.

    Ahmed, Naghia; Ronchi, Dario; Comi, Giacomo Pietro

    2015-01-01

    Replication and maintenance of mtDNA entirely relies on a set of proteins encoded by the nuclear genome, which include members of the core replicative machinery, proteins involved in the homeostasis of mitochondrial dNTPs pools or deputed to the control of mitochondrial dynamics and morphology. Mutations in their coding genes have been observed in familial and sporadic forms of pediatric and adult-onset clinical phenotypes featuring mtDNA instability. The list of defects involved in these disorders has recently expanded, including mutations in the exo-/endo-nuclease flap-processing proteins MGME1 and DNA2, supporting the notion that an enzymatic DNA repair system actively takes place in mitochondria. The results obtained in the last few years acknowledge the contribution of next-generation sequencing methods in the identification of new disease loci in small groups of patients and even single probands. Although heterogeneous, these genes can be conveniently classified according to the pathway to which they belong. The definition of the molecular and biochemical features of these pathways might be helpful for fundamental knowledge of these disorders, to accelerate genetic diagnosis of patients and the development of rational therapies. In this review, we discuss the molecular findings disclosed in adult patients with muscle pathology hallmarked by mtDNA instability. PMID:26251896

  1. Effects of Aging and Adult-Onset Hearing Loss on Cortical Auditory Regions

    Cardin, Velia

    2016-01-01

    Hearing loss is a common feature in human aging. It has been argued that dysfunctions in central processing are important contributing factors to hearing loss during older age. Aging also has well documented consequences for neural structure and function, but it is not clear how these effects interact with those that arise as a consequence of hearing loss. This paper reviews the effects of aging and adult-onset hearing loss in the structure and function of cortical auditory regions. The evidence reviewed suggests that aging and hearing loss result in atrophy of cortical auditory regions and stronger engagement of networks involved in the detection of salient events, adaptive control and re-allocation of attention. These cortical mechanisms are engaged during listening in effortful conditions in normal hearing individuals. Therefore, as a consequence of aging and hearing loss, all listening becomes effortful and cognitive load is constantly high, reducing the amount of available cognitive resources. This constant effortful listening and reduced cognitive spare capacity could be what accelerates cognitive decline in older adults with hearing loss. PMID:27242405

    Replication and maintenance of mtDNA entirely relies on a set of proteins encoded by the nuclear genome, which include members of the core replicative machinery, proteins involved in the homeostasis of mitochondrial dNTPs pools or deputed to the control of mitochondrial dynamics and morphology. Mutations in their coding genes have been observed in familial and sporadic forms of pediatric and adult-onset clinical phenotypes featuring mtDNA instability. The list of defects involved in these disorders has recently expanded, including mutations in the exo-/endo-nuclease flap-processing proteins MGME1 and DNA2, supporting the notion that an enzymatic DNA repair system actively takes place in mitochondria. The results obtained in the last few years acknowledge the contribution of next-generation sequencing methods in the identification of new disease loci in small groups of patients and even single probands. Although heterogeneous, these genes can be conveniently classified according to the pathway to which they belong. The definition of the molecular and biochemical features of these pathways might be helpful for fundamental knowledge of these disorders, to accelerate genetic diagnosis of patients and the development of rational therapies. In this review, we discuss the molecular findings disclosed in adult patients with muscle pathology hallmarked by mtDNA instability.

    Background Several observational studies have suggested that outdoor air pollution may induce or aggravate asthma. However, epidemiological results are inconclusive due to the presence of numerous moderators which influence this association. The goal of this study was to assess the relationship between outdoor air pollutants and moderate or severe asthma exacerbations in children and adults through a systematic review and multilevel meta-analysis. Material and methods We searched studies published in English on PubMed, Scopus, and Google Scholar between January 2000 and October 2016. Studies following a case-crossover design with records of emergency departments and/or hospital admissions as a surrogate of moderate or severe asthma exacerbations were selected. A multilevel meta-analysis was employed, taking into account the potential clustering effects within studies examining more than one lag. Odds ratios (ORs) and 95% confidence intervals were estimated. A subgroup analysis in children aged 0 to 18 years and a sensitivity analysis based on the quality of the included studies as defined in the Newcastle-Ottawa Scale were performed. Publication bias was evaluated through visual inspection of funnel plots and by a complementary search of grey literature. (Prospero Registration number CRD42015032323). Results Database searches retrieved 208 records, and finally 22 studies were selected for quantitative analysis. All pollutants except SO2 and PM10 showed a significant association with asthma exacerbations (NO2: 1.024; 95% CI: 1.005,1.043, SO2: 1.039; 95% CI: 0.988,1.094), PM10: 1.024; 95% CI: 0.995,1.053, PM2.5: 1.028; 95% CI: 1.009,1.047, CO: 1.045; 95% CI: 1.005,1.086, O3: 1.032; 95% CI: 1.005,1.060. In children, the association was significant for NO2, SO2 and PM2.5. Conclusion This meta-analysis provides evidence of the association between selected air pollutants and asthma exacerbations for different lags. PMID:28319180

    Background Emerging safety issues associated with long-acting beta2-agonist (LABA) have led to multiple regulatory activities by the US Food and Drug Administration (FDA) since 2003, including Drug Safety Communications (DSCs) in 2010. These DSCs had three specific recommendations for the safe use of LABA products in adult asthma treatment. Methods We examined the initiation of LABA-containing products for adult asthma treatment using an intermittent time series approach in a claims database from 2003 to 2012. We assessed the alignment of dispensing patterns with the following 2010 FDA recommendations: 1) contraindicated use of single-ingredient (SI)-LABA without an asthma controller medication (ACM); 2) a LABA should only be used when asthma is not adequately controlled on inhaled corticosteroids (ICSs) or ACM; and 3) step-down asthma therapy (e.g., discontinue LABA) when asthma control is achieved. Results There were 477,922 adults (18–64 years old) dispensed a new LABA during 2003–2012. Among LABA initiators, patients who initiated an SI-LABA and who did “not” have an ACM dispensed on the same date decreased from >9% in 2003 (the initial labeling change) to <2% post 2010 DSCs (p-value <0.0001 in the segmented regression model). The proportion of asthma patients dispensed an ICS in 6 months prior to initiating LABA treatment did not increase. The proportion of patients with longer than 4 months of continuous treatment did not decrease over the study period. Conclusion Although the decrease in SI-LABA initiation is consistent with FDA’s recommendations, low ICS dispensing before initiating a LABA and LABA continuation practices require further efforts to move toward the recommended safe practices.

    Infection with Mycoplasma pneumoniae has been shown to exacerbate asthma in humans. However, the role of M. pneumoniae in the pathogenesis of chronic asthma has not been defined. Eighteen asthmatics with chronic, stable asthma and 11 nonasthmatic control subjects underwent evaluation of the upper and lower airways and serologic analysis to determine the presence of M. pneumoniae, Chlamydia pneumoniae, and seven respiratory viruses through culture, enzyme-linked immunoassay (EIA) and polymerase chain reaction (PCR). M. pneumoniae was detected by PCR in 10 of 18 asthmatics and one of 11 control subjects (p = 0.02). In nine of the 10 patients, the organism was detected in bronchoalveolar lavage or bronchial biopsies. Seven of 18 asthmatics and one of 11 control subjects were also positive for M. fermentans and M. genitalium by PCR. All patients' cultures, EIAs, and serology were negative for M. pneumoniae. All PCR and cultures were negative for C. pneumoniae, and all EIAs for respiratory viruses were negative in all subjects. Nine asthmatics and one control subject exhibited positive serology for C. pneumoniae (p = 0.05). M. pneumoniae was present in the lower airways of chronic, stable asthmatics with greater frequency than control subjects, and may play a role in the pathogenesis of chronic asthma.

    Purpose This study examined the association between time of onset of hearing loss (childhood vs. adulthood) and self-reported hearing handicap in adults. Methods This is a population-based cohort study of 2,024 adults (mean = 48 years) with hearing loss (binaural pure-tone average 0.5–4 kHz ≥ 20 dB HL) who completed a hearing handicap questionnaire. In childhood, the same persons (N = 2,024) underwent audiometry in a school investigation (at ages 7, 10, and 13 years), in which 129 were diagnosed with sensorineural hearing loss (binaural pure-tone average 0.5–4 kHz ≥ 20 dB HL), whereas 1,895 had normal hearing thresholds. Results Hearing handicap was measured in adulthood as the sum-score of various speech perception and social impairment items (15 items). The sum-score increased with adult hearing threshold level (p < .001). After adjustment for adult hearing threshold level, hearing aid use, adult age, sex, and socioeconomic status, there was no significant difference in hearing handicap sum-score between the group with childhood-onset hearing loss (n = 129) and the group with adult-onset hearing loss (n = 1,895; p = .882). Conclusion Self-reported hearing handicap in adults increased with hearing threshold level. After adjustment for adult hearing threshold level, this cohort study revealed no significant association between time of onset of hearing loss (childhood vs. adulthood) and self-reported hearing handicap.

    Welding-related asthma is well recognised but less is known about rhinitis in relation to welding. The aim here, was to study associations between welding, rhinitis and asthma in a general population sample, and factors influencing selection into and out of a welding occupation.Adult-onset asthma and non-infectious rhinitis were investigated in the international multicentre population-based Respiratory Health in Northern Europe (RHINE) study, including 16,191 responders aged 26-54 years. Ever welding (n=2181), welding >25% of working time (n=747), and welding in stainless steel >6 months (n=173) were assessed by questionnaire. Subjects with rhinitis or asthma onset when aged <18 years were excluded. Incidence rates for asthma and rhinitis were calculated from year of disease onset, and start and end of welding job. Cox's proportional hazard models adjusting for age, sex, parental education and study centre, and Kaplan-Meier curves were used.Rhinitis incidence was higher among welders (hazard ratio (HR) 1.4, 95% CI 1.3-1.6), consistent in men and women, and across centres (pheterogeneity=0.4). In men, asthma incidence was higher among welders (HR 1.4, 95% CI 1.04-1.97). Quitting welding was indicated higher after adult-onset rhinitis (HR 1.1, 95% CI 1.0-1.3). Adult-onset rhinitis and asthma was higher among welders, consistent across population samples from Northern Europe. No pre-employment selection was found, whereas selection out of welding jobs was suggested.

    AIM: To investigate the evolution of disease phenotype in adult and pediatric onset Crohn’s disease (CD) populations, diagnosed between 1977 and 2008. METHODS: Data of 506 incident CD patients were analyzed (age at diagnosis: 28.5 years, interquartile range: 22-38 years). Both in- and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which included incident patients diagnosed between January 1, 1977 and December 31, 2008 in adult and pediatric onset CD populations. Disease phenotype according to the Montreal classification and long-term disease course was analysed according to the age at onset in time-dependent univariate and multivariate analysis. RESULTS: Among this population-based cohort, seventy-four (12.8%) pediatric-onset CD patients were identified (diagnosed ≤ 17 years of age). There was no significant difference in the distribution of disease behavior between pediatric (B1: 62%, B2: 15%, B3: 23%) and adult-onset CD patients (B1: 56%, B2: 21%, B3: 23%) at diagnosis, or during follow-up. Overall, the probability of developing complicated disease behaviour was 49.7% and 61.3% in the pediatric and 55.1% and 62.4% in the adult onset patients after 5- and 10-years of follow-up. Similarly, time to change in disease behaviour from non stricturing, non penetrating (B1) to complicated, stricturing or penetrating (B2/B3) disease was not significantly different between pediatric and adult onset CD in a Kaplan-Meier analysis. Calendar year of diagnosis (P = 0.04), ileal location (P < 0.001), perianal disease (P < 0.001), smoking (P = 0.038) and need for steroids (P < 0.001) were associated with presence of, or progression to, complicated disease behavior at diagnosis and during follow-up. A change in disease location was observed in 8.9% of patients and it was associated with smoking status (P = 0.01), but not with age at diagnosis. CONCLUSION: Long

    The hypothalamus plays a crucial role in the control of the energy balance and also retains neurogenic potential into adulthood. Recent studies have reported the severe alteration of the cell turn-over in the hypothalamus of obese animals and it has been proposed that a neurogenic deficiency in the hypothalamus could be involved in the development of obesity. To explore this possibility, we examined hypothalamic cell renewal during the homeostatic response to dietary fat in mice, i.e., at the onset of diet-induced obesity. We found that switching to high-fat diet (HFD) accelerated cell renewal in the hypothalamus through a local, rapid and transient increase in cell proliferation, peaking three days after introducing the HFD. Blocking HFD-induced cell proliferation by central delivery of an antimitotic drug prevented the food intake normalization observed after HFD introduction and accelerated the onset of obesity. This result showed that HFD-induced dividing brain cells supported an adaptive anorectic function. In addition, we found that the percentage of newly generated neurons adopting a POMC-phenotype in the arcuate nucleus was increased by HFD. This observation suggested that the maturation of neurons in feeding circuits was nutritionally regulated to adjust future energy intake. Taken together, these results showed that adult cerebral cell renewal was remarkably responsive to nutritional conditions. This constituted a physiological trait required to prevent severe weight gain under HFD. Hence this report highlighted the amazing plasticity of feeding circuits and brought new insights into our understanding of the nutritional regulation of the energy balance. PMID:23967273

    The objectives of this work were to investigate the frequency of severe asthma (SA) according to WHO definition and to compare SA patients' characteristics with those of non-severe asthma (NSA); secondly, to investigate the level of control reached throughout a period of regular treatment. Between 1-1-2005 and 12-31-2014, 471 medical records from patients with bronchial asthma assisted in Buenos Aires City were analyzed. SA frequency was 40.1% (189/471), being significantly higher among patients from the public health system (47.7%, 108/226 vs. 33%, 81/245, p = 0.001). SA patients were older than NSA ones (51.3 ± 17.4 vs. 42.6 ± 17.1 years, p = 0.000), presented longer time since onset of the disease (median 30 vs. 20 years, p = 0.000), lower educational levels (secondary level or higher 41.7% vs. 58.1%, p = 0.000), lower frequency of rhinitis (47% vs. 60.6%, p = 0.004), more severe levels of airway obstruction (FEV% 50.2 ± 13.7 vs. 77.7 ± 12.4, p = 0.000), more frequent antecedents of Near Fatal Asthma (11.1% vs. 2.8%, p = 0.000), higher levels of serum IgE (median of 410 vs. 279 UI/l, p = 0.01) and higher demand of systemic steroids requirements and hospitalizations (68.7% vs. 50.7%, p = 0.000 and 37.5% vs. 15.9%, p = 0.000, respectively). A 30.6% of SA patients (58/189) reached a follow-up period of 12 months, 13 (22.5%) of whom reached the controlled asthma level. The frequency of SA found seems to be considerable. Multicenter studies to investigate the levels of control reached by SA patients with access to proper treatment are recommended.

    Summary Background and objectives To date, very few cases with adult-onset focal segmental glomerulosclerosis (FSGS) carrying NPHS2 variants have been described, all of them being compound heterozygous for the p.R229Q variant and one pathogenic mutation. Design, setting, participants, & measurements Mutation analysis was performed in 148 unrelated Spanish patients, of whom 50 presented with FSGS after 18 years of age. Pathogenicity of amino acid substitutions was evaluated through an in silico scoring system. Haplotype analysis was carried out using NPHS2 single nucleotide polymorphism and microsatellite markers. Results Compound heterozygous or homozygous NPHS2 pathogenic mutations were identified in seven childhood-onset steroid-resistant nephrotic syndrome (SRNS) cases. Six additional cases with late childhood- and adult-onset SRNS were compound heterozygotes for p.R229Q and one pathogenic mutation, mostly p.A284V. p.R229Q was more frequent among SRNS cases relative to controls (odds ratio = 2.65; P = 0.02). Significantly higher age at onset of the disease and slower progression to ESRD were found in patients with one pathogenic mutation plus the p.R229Q variant in respect to patients with two NPHS2 pathogenic mutations. Conclusions NPHS2 analysis has a clinical value in both childhood- and adult-onset SRNS patients. For adult-onset patients, the first step should be screening for p.R229Q and, if positive, for p.A284V. These alleles are present in conserved haplotypes, suggesting a common origin for these substitutions. Patients carrying this specific NPHS2 allele combination did not respond to corticoids or immunosuppressors and showed FSGS, average 8-year progression to ESRD, and low risk for recurrence of FSGS after kidney transplant.

    Background Panic disorder (PD) is a common anxiety disorder among asthmatic patients with overlapping symptoms (e.g., hyperventilation). However, the longitudinal impact of PD on asthma control remains poorly understood. This study assessed the impact of PD and panic-anxiety on asthma control over a 4.3-year follow-up in 643 adult asthmatic patients. Methods Consecutive patients presenting to a tertiary asthma clinic underwent a sociodemographic, medical history, and psychiatric (Primary Care Evaluation of Mental Disorders) interview and completed questionnaires including the Anxiety Sensitivity Index (ASI) to assess panic-anxiety. At follow-up, patients completed the Asthma Control (ACQ) and Asthma Quality of Life (AQLQ) questionnaires and reported emergency department visits and hospitalizations during the follow-up. Results Baseline frequency of PD was 10% (n = 65). In fully adjusted models, analyses revealed that PD and ASI scores predicted worse follow-up ACQ total scores (β = 0.292, p = .037; β = 0.012, p = .003) but not AQLQ total scores. ASI scores also predicted greater nocturnal and waking symptoms, activity limitations, and bronchodilator use on the ACQ (β = 0.012-0.018, p < .05) as well as lower symptom (β = -0.012, p = .006) and emotional distress (β = -0.014, p = .002) subscale scores on the AQLQ. Neither PD nor ASI scores were associated with hospitalizations, although ASI scores (but not PD) were associated with an increased risk of emergency department visits (relative risk = 1.023, 95% confidence interval = 1.001-1.044). Conclusions PD and anxiety sensitivity are prospectively associated with poorer asthma control and may be important targets for treatment.

    Background Asian dust (AD) exposure exacerbates pulmonary dysfunction in patients with asthma. Asthma–chronic obstructive pulmonary disease overlap syndrome (ACOS), characterized by coexisting symptoms of asthma and chronic obstructive pulmonary disease, is considered a separate disease entity. Previously, we investigated the effects of AD on pulmonary function in adult patients with asthma. Here, we present the findings of our further research on the differences in the effects of AD exposure on pulmonary function between patients with asthma alone and those with ACOS. Methods Between March and May 2012, we conducted a panel study wherein we monitored daily peak expiratory flow (PEF) values in 231 adult patients with asthma. These patients were divided into 190 patients with asthma alone and 41 patients with ACOS in this study. Daily AD particle levels were measured using light detection and ranging systems. Two heavy AD days (April 23 and 24) were determined according to the Japan Meteorological Agency definition. A linear mixed model was used to estimate the association between PEF and AD exposure. Results Increments in the interquartile range of AD particles (0.018 km−1) led to PEF changes of −0.50 L/min (95% confidence interval, −0.98 to −0.02) in patients with asthma alone and −0.11 L/min (−0.11 to 0.85) in patients with ACOS. The PEF changes after exposure to heavy AD were −2.21 L/min (−4.28 to −0.15) in patients with asthma alone and −2.76 L/min (−6.86 to 1.35) in patients with ACOS. In patients with asthma alone, the highest decrease in PEF values was observed on the heavy AD day, with a subsequent gradual increase over time. Conclusion Our results suggest that the effects of AD exposure on pulmonary function differ between patients with asthma alone and ACOS, with the former exhibiting a greater likelihood of decreased pulmonary function after AD exposure.

    Few interventions to improve asthma outcomes have targeted low-income minority adults. Even fewer have focused on the real-world practice where care is delivered. We adapted a patient navigator, here called a Patient Advocate (PA), a term preferred by patients, to facilitate and maintain access to chronic care for adults with moderate or severe asthma and prevalent co-morbidities recruited from clinics serving low-income urban neighborhoods. We describe the planning, design, methodology (informed by patient and provider focus groups), baseline results, and challenges of an ongoing randomized controlled trial of 312 adults of a PA intervention implemented in a variety of practices. The PA coaches, models, and assists participants with preparations for a visit with the asthma clinician; attends the visit with permission of participant and provider; and confirms participants' understanding of what transpired at the visit. The PA facilitates scheduling, obtaining insurance coverage, overcoming patients' unique social and administrative barriers to carrying out medical advice and transfer of information between providers and patients. PA activities are individualized, take account of comorbidities, and are generalizable to other chronic diseases. PAs are recent college graduates interested in health-related careers, research experience, working with patients, and generally have the same race/ethnicity distribution as potential participants. We test whether the PA intervention, compared to usual care, is associated with improved and sustained asthma control and other asthma outcomes (prednisone bursts, ED visits, hospitalizations, quality of life, FEV1) relative to baseline. Mediators and moderators of the PA-asthma outcome relationship are examined along with the intervention's cost-effectiveness.

    We studied two monozygotic twins, born to first cousins, affected by a multisystem disease. At birth, they both presented with bilateral cryptorchidism and malformations. Since early adulthood, they developed a slowly progressive neurological syndrome, with cerebellar and pyramidal signs, cognitive impairment, and depression. Dilating cardiomyopathy is also present in both. By whole-exome sequencing, we found a homozygous nucleotide change in XRCC4 (c.673C>T), predicted to introduce a premature stop codon (p.R225*). XRCC4 transcript levels were profoundly reduced, and the protein was undetectable in patients' skin fibroblasts. XRCC4 plays an important role in non-homologous end joining of DNA double-strand breaks (DSB), a system that is involved in repairing DNA damage from, for example, ionizing radiations. Gamma-irradiated mutant cells demonstrated reduction, but not abolition, of DSB repair. In contrast with embryonic lethality of the Xrcc4 KO mouse, nonsense mutations in human XRCC4 have recently been associated with primordial dwarfism and, in our cases, with adult-onset neurological impairment, suggesting an important role for DNA repair in the brain. Surprisingly, neither immunodeficiency nor predisposition to malignancy was reported in these patients. PMID:25872942

    2016-01-01

    Testosterone deficiency (TD) has become a growing concern in the field of men’s sexual health, with an increasing number of men presenting for evaluation of this condition. Given the increasing demand for testosterone replacement therapy (TRT), a panel of experts met in August of 2015 to discuss the treatment of men who present for evaluation in the setting of low or normal gonadotropin levels and the associated signs and symptoms of hypogonadism. This constellation of factors can be associated with elements of both primary and secondary hypogonadism. Because this syndrome commonly occurs in men who are middle-aged and older, it was termed adult-onset hypogonadism (AOH). AOH can be defined by the following elements: low levels of testosterone, associated signs and symptoms of hypogonadism, and low or normal gonadotropin levels. Although there are significant benefits of TRT for patients with AOH, candidates also need to understand the potential risks. Patients undergoing TRT will need to be monitored regularly because there are potential complications that can develop with long-term use. This review is aimed at providing a deeper understanding of AOH, discussing the benefits and risks of TRT, and outlining each modality of TRT in use for AOH. PMID:28078213

    Krabbe disease (KD) is an autosomal recessive neurodegenerative disorder caused by defective β-galactosylceramidase (GALC), a lysosomal enzyme responsible for cleavage of several key substrates including psychosine. Accumulation of psychosine to the cytotoxic levels in KD patients is thought to cause dysfunctions in myelinating glial cells based on a comprehensive study of demyelination in KD. However, recent evidence suggests myelin-independent neuronal death in the murine model of KD, thus indicating defective GALC in neurons as an autonomous mechanism for neuronal cell death in KD. These observations prompted us to generate induced neurons (iNeurons) from two adult-onset KD patients carrying compound heterozygous mutations (p.[K563*];[L634S]) and (p.[N228_S232delinsTP];[G286D]) to determine the direct contribution of autonomous neuronal toxicity to KD. Here we report that directly converted KD iNeurons showed not only diminished GALC activity and increased psychosine levels, as expected, but also neurite fragmentation and abnormal neuritic branching. The lysosomal-associated membrane proteins 1 (LAMP1) was expressed at higher levels than controls, LAMP1-positive vesicles were significantly enlarged and fragmented, and mitochondrial morphology and its function were altered in KD iNeurons. Strikingly, we demonstrated that psychosine was sufficient to induce neurite defects, mitochondrial fragmentation, and lysosomal alterations in iNeurons derived in healthy individuals, thus establishing the causal effect of the cytotoxic GALC substrate in KD and the autonomous neuronal toxicity in KD pathology.

Such data in general are composed of the genomic content from two contrasting phenotypes, e.g., disease versus control populations, and the analysis proceeds under the hypothesis that populational dissimilarities might reveal disease risk alleles. The proposed suite of new methods is in part based on information theory (Shannon in Bell Syst Tech J 27:379-423, 1948a; Bell Syst Tech J 27:623-656, 1948b; Jaynes in Phys Rev 106:620-630, 1957), and strong evidence will be given of the effectiveness of this new approach. The methodology extends naturally and successfully to predicting genomic disposition to disease arising from large collections of weakly contributing genomic loci. Evidence will be advanced that the example of adult-onset diabetes ("type 2 diabetes") is such a candidate disease, and in this case, probably for the first time, it can be demonstrated that disease prediction is possible. Another novel element of this study is the search and identification of potential beneficial genomic loci that may counter a disease. The generality of the methodology suggests that it might extend to other diseases.

    Adult-onset Still disease (AOSD) is a rare autoinflammatory syndrome characterized by recurring fevers, arthralgia, and consistent laboratory abnormalities that include leukocytosis and hyperferritinemia. Skin findings accompany the disease in nearly 90% of the cases. Early reports described evanescent, pruritic, salmon-pink or urticarial lesions, referred to as the typical eruption of AOSD. Histopathologic findings consist of superficial perivascular dermatitis with varying number of interstitial neutrophils. Later reports described a more persistent rash that tended to be photodistributed, hyperpigmented, often in a linear configuration, sometimes in a rippled pattern, referred to as the atypical eruption of AOSD. The presence of individual necrotic keratinocytes in the upper spinous layer has been the consistent histopathologic finding. The persistent rash may not represent an atypical presentation of AOSD as recent reports indicate a high prevalence of the rash. Emerging data also suggest that patients with persistent eruption have a worse prognosis. The recognition of the clinical and histopathological findings of skin eruptions of AOSD may facilitate an earlier diagnosis, potentially improving disease outcome. Herein, clinical and histopathological features of cutaneous manifestation of AOSD in two Asian women are highlighted accompanied by relevant review of the disease.

    Adult-onset Still disease (AOSD) is a systemic inflammatory disorder that is clinically characterized by a heterogeneous constellation of symptoms and signs. Though an evanescent eruption is the classic cutaneous finding, recent literature has highlighted atypical rashes associated with Still disease. A second emerging concept in presentations of AOSD is its association with malignancy. This review focuses on these concepts: the clinical spectrum of atypical skin manifestations and AOSD as a paraneoplastic phenomenon. PubMed-MEDLINE was screened for peer-reviewed articles describing atypical presentations of AOSD and cases associated with malignancy. Erythematous, brown or violaceous, persistent papules and plaques were the most common cutaneous finding (28/30 [93%]). Linear configurations were also rarely described. Of these patients, 81% concurrently had the typical evanescent skin eruption. There were 31 patients with associated malignancies, most commonly breast cancer and lymphoma. The diagnosis of malignancy did not precede or immediately follow a clinical presentation otherwise consistent with AOSD in a considerable subset of patients (42%). Understanding the cutaneous spectrum of AOSD and heightened awareness for its delayed association with malignancy may lead to improved recognition of cutaneous variants and reinforce the need for diagnostic evaluation and long-term follow-up for malignancy in patients with this clinical presentation.

    Deficiency of argininosuccinate synthetase (ASS) causes citrullinemia in human beings. Type II citrullinemia is found in most patients with adult-onset citrullinemia in Japan, and ASS deficiency is found specifically in the liver. Previous studies have shown that the decrease of hepatic ASS activity is caused by a decrease in enzyme protein with normal kinetic properties and that there were no apparent abnormalities in the amount, translational activity, and gross structure of hepatic ASS mRNA. In the present work, the authors show by sequencing analysis that there was no mutation in the ASS mRNA from two patients with type II citrullinemia. The authors also report RFLP analysis of a consanguineous family with type II citrullinemia, by using three DNA polymorphisms located within the ASS gene locus. In spite of having consanguineous parents, the patient was not a homozygous haplotype for the ASS gene. The RFLP analysis of 16 affected patients from consanguineous parents showed that 5 of 16 patients had the heterozygous pattern for one of the three DNA probes and that the frequency of the heterozygous haplotype was not different from the control frequency. These results suggest that the primary defect of type II citrullinemia is not within the ASS gene locus. 29 refs., 1 fig., 3 tabs.

    Adult-onset Still disease (AOSD) is an uncommon disorder characterized by fever, polyarthralgia, elevated white blood cell count, and a maculopapular rash, the histologic features of which have not been well-known. A 55-year-old Asian woman presented initially with a "burning" and severely pruritic eruption on her face, hands, and arms, thought clinically to be urticaria. Within 1 month, she began spiking high fevers, developed diffuse joint pain, and had marked elevations of ferritin, C-reactive protein, and erythrocyte sedimentation rate, characteristic of AOSD. The cutaneous eruption became more widespread, involving the trunk, scalp, and remainder of the extremities, with diffuse thickening of the skin with papular and linear hyperpigmentation and accentuation. Biopsies from several locations showed focal hyperkeratosis associated with dyskeratotic keratinocytes with a peculiar, distinctive distribution in the upper epidermis and cornified layers. In addition, increased dermal mucin was present, with minimal fibroblast proliferation and inflammation. This unusual combination of diffuse dermal mucinosis and a unique pattern of dyskeratosis can present a challenge in generating an accurate differential diagnosis, and may represent an unusual response to chronic scratching or be a distinctive histologic manifestation of AOSD.

    OBJECTIVE The risk factors for middle-age onset of type 2 diabetes are well known. However, information is scant regarding the age onset of type 2 diabetes and its correlates in community-based black and white relatively young adults. RESEARCH DESIGN AND METHODS This prospective cohort study consisted of normoglycemic (n = 2,459) and type 2 diabetic (n = 144) adults aged 18–50 years who were followed for an average of 16 years. RESULTS The incidence rate of the onset of type 2 diabetes was 1.6, 4.3, 3.9, and 3.4 per 1,000 person-years for age-groups 18–29, 30–39, and 40–50 and total sample, respectively. Incidences of diabetes increased with age by race and sex groups (P for trend ≤0.01); higher in black females versus white females and blacks versus whites in total sample (P < 0.05). In a multivariable Cox model, baseline parental diabetes (hazard ratio [HR] 5.24) and plasma insulin were significantly associated with diabetes incidence at the youngest age (18–29 years); black race, BMI, and glucose at age 30–39 years; female sex, parental diabetes (HR 2.44), BMI, ratio of triglycerides and HDL cholesterol (TG/HDL-C ratio), and glucose at age 40–50 years; and black race, parental diabetes (HR 2.44), BMI, TG/HDL-C ratio, and glucose in whole cohort. Further, patients with diabetes, regardless of age onset, displayed a significantly higher prevalence of maternal history of diabetes at baseline (P < 0.01). CONCLUSIONS In relatively young adults, predictability of baseline cardiometabolic risk factors along with race, sex, and parental history of diabetes for the onset of type 2 diabetes varied by age-group. These findings have implications for early prevention and intervention in relatively young adults. PMID:22399694

    Objectives To determine longitudinal changes in the occurrence of medical complications in adults with pediatric-onset spinal cord injury (SCI). Design Longitudinal study of long-term outcomes. Setting Community. Participants Individuals who had sustained an SCI before age 19, were 23 years of age or older at initial interview, and followed annually between 1996 and 2011. They were classified into four American Spinal Injury Association (ASIA) Impairment Scale (AIS) severity groups: C1–4 AIS ABC, C5–8 AIS ABC, T1–S5 AIS ABC, AIS D. Outcome measures Generalized estimating equation (GEE) models were formulated to obtain the odds ratio (OR) of having a medical complication over time. Results A total of 1793 interviews were conducted among 226 men and 125 women (86% Caucasian; age at baseline, 26.7 ± 3.6 years; time since injury at baseline, 12.9 ± 5.2 years). Odds of complication occurrence over time varied among severity groups, with increased ORs of severe urinary tract infection (1.05, confidence interval (CI) 1.02–1.09), autonomic dysreflexia (AD) (1.09, CI 1.05–1.14), spasticity (1.06, CI 1.01–1.11), pneumonia/respiratory failure (1.09, CI 1.03–1.16), and hypertension/cardiac disease (1.07, CI 1.01–1.15) in the C1-4 ABC group; AD (1.08, CI 1.04–1.13) and pneumonia/respiratory failure (1.09, CI 1.02–1.16) in the C5–8 ABC group; and hypertension/cardiac disease (1.08, CI 1.02–1.14) in the T1–S5 ABC group. Upper extremity joint pain had increased odds of occurrence in all injury severity groups. Conclusion The significantly increased odds of having medical complications over time warrants awareness of risk factors and implementation of preventive measures to avoid adverse consequences of complications and to maintain independence in individuals with pediatric-onset SCI.

    Background Hereditary diffuse leukoencephalopathy with neuroaxonal spheroids (HDLS) is a hereditary, adult onset leukodystrophy which is characterised by the presence of axonal loss, axonal spheroids and variably present pigmented macrophages on pathological examination. It most frequently presents in adulthood with dementia and personality change. HDLS has recently been found to be caused by mutations in the colony stimulating factor-1 receptor (CSF1R) gene. Methods In this study, we sequenced the CSF1R gene in a cohort of 48 patients from the UK, Greece and Ireland with adult onset leukodystrophy of unknown cause. Results Five pathogenic mutations were found, including three novel mutations. The presentations ranged from suspected central nervous system (CNS) vasculitis to extrapyramidal to cognitive phenotypes. The case histories and imaging are presented here, in addition to neuropathological findings from two cases with novel mutations. Conclusion We estimate that CSF1R mutations account for 10% of idiopathic adult onset leukodystrophies and that genetic testing for CSF1R mutations is essential in adult patients presenting with undefined CNS vasculitis or a leukodystrophy with prominent neuropsychiatric signs or dementia.

    Asthma morbidity is high among inner-city minority adults. Improving access to care and patient-provider communication are believed essential for improving outcomes. Access and communication in turn increasingly rely on information technology including features of the Electronic Health Record. Its patient portal offers web-based communication with providers and practices. How patients with limited resources and educational opportunities can benefit from this portal is unclear. In contrast, home visits by community health workers (CHWs) have improved access to care for asthmatic children and promoted caretaker-clinician communication. We describe the planning, design, and methodology of an ongoing randomized controlled trial for 300 adults, predominantly African American and Hispanic/Latino, with uncontrolled asthma recruited from low income urban neighborhoods who are directed to the most convenient internet access and taught to use the portal, with and without home visits from a CHW. The study 1) compares the effects of the 1-year interventions on asthma outcomes (improved asthma control, quality of life; fewer ED visits and hospitalizations for asthma or any cause), 2) evaluates whether communication (portal use) and access (appointments made/kept) mediate the interventions' effects on asthma outcomes, and 3) investigates effect modification by literacy level, primary language, and convenience of internet access. In home visits, CHWs 1) train patients to competency in portal use, 2) enhance care coordination, 3) communicate the complex social circumstances of patients' lives to providers, and 4) compensate for differences in patients' health literacy skills. The practical challenges to design and implementation in the targeted population are presented.

    Background: Current healthcare policy advocates patient participation in treatment decision making. However, in asthma there is little evidence regarding patients' views on such involvement. This study explored the preferred and perceived level of involvement in treatment decisions, rationales for role preference, perceived facilitators of/barriers to involvement, and the interrelationship of role preference and demographic variables in a sample of patients with asthma. Methods: A cross sectional survey was performed of 230 adults with clinician diagnosed asthma from 10 primary care sites and one specialist respiratory centre in north-west England. Preferred role in treatment decisions was assessed using the Control Preferences Scale. Results: Fifty five (23.9%) preferred an active role, 82 (35.7%) a collaborative role, and 93 (40.4%) a passive role; 19 (8.2%) perceived their role as active compared with 45 (19.6%) collaborative and 166 (72.2%) passive. Only 33.5% (n = 77) of respondents attained their most preferred role; 55.2% (n = 127) were less involved than they preferred. Patient related, professional related, and organisational factors, especially quality and duration of consultations, facilitated or hampered involvement. Role preferences were not strongly associated with demographic variables or asthma severity. Conclusions: This study in patients with asthma highlights the fact that there is a need for professional and patient education regarding partnership working, skilful communication, and innovative approaches to service delivery.

    A case of adult-onset ataxia-telangiectasia (AT) is presented, with debut at the age of 18 years and survival into the fourth decade. The clinical picture included cerebellar ataxia, distal weakness and hypopalesthesia in the lower limbs, oculomotor apraxia, dysarthria, and conjunctival telangiectasiae. Carcinoembrionic antigen was raised in plasma. MR imaging showed atrophy of the cerebellar vermis and thinning of the spinal cord. Deficiencies of gamma-aminobutyric acid and glutamate have been found in the cerebellar cortex in a case of AT. These were attributed to the loss of Purkinje cells and granule cells. In spite of some ataxias having improved with the gabaergic drugs gabapentin and tiagabine, the administration of gabapentin, acetazolamide and a placebo, did not benefit this patient. Pregabalin, 225 mg/day, ameliorated the ataxia unexpectedly, with further improvement after the addition of tiagabine. The authors suggest that the beneficial effect observed might have been due, either to the higher affinity of pregabalin towards alpha2-delta, a subtype of the alpha2-delta subunit which forms part of the voltage-gated calcium channel; either to the profusion of this subtype in the Purkinje cell layer, or to its larger capacity to let calcium into the neuron; or to the combination of these. These differences with gabapentin could explain the higher power of pregabalin in the stimulation of the cerebellar structures, thus justifying the improvement of ataxia in this case of AT. A synergistic effect with pregabalin is proposed as the cause of the improvement obtained with the addition of tiagabine.

    Background The psychiatric health burden of prisoners is substantial. However, there is a lack of high-quality studies of psychiatric disorders among young adults with a high risk of reoffending. Aims To investigate the lifetime prevalence of psychiatric disorders and use of mental health services among young male violent offenders and the impact of childhood-onset conduct disorder (COCD). Method A nationally representative cohort (n = 270, age 18–25) of male offenders was followed back in medical records and clinically assessed by gold standard methods. Lifetime prevalences are presented together with odds ratios (ORs) as risk estimates in relation to COCD. Results Previous use of psychiatric services among the participants was high but their lifetime psychiatric morbidity was even higher, with 93% meeting criteria for at least one Axis I disorder. The COCD group was overrepresented in most clinical categories and carried five times higher odds (OR = 5.1, 95% CI 2.0–12.8) of a psychotic disorder, three times higher odds (OR = 3.2, 95% CI 1.2–8.5) of a substance use disorder and two times higher odds of a mood disorder (OR = 2.3, 95% CI 1.3–4.0) or anxiety disorder (OR = 2.0, 95% CI 1.1–3.5). Conclusions The mental health burden is substantial among young violent offenders, and COCD is an important indicator of future mental health problems which must be a priority for public health efforts.

    Fetal exposure to parental smoking may lead to developmental adaptations and promote various diseases in later life. This study evaluated the associations of parental smoking during pregnancy with the risk of hypertension in the daughter in adulthood, and assessed whether these associations are explained by birth weight or body weight throughout life. We used data on 33086 participants of the Nurses' Health Study II and the Nurses' Mothers' Cohort. Cox proportional hazards models were used to examine the associations of maternal and paternal smoking during pregnancy with the nurse daughter, with self-reported physician-diagnosed hypertension from 1989 until 2007. Overall, 8575 (25.9%) mothers and 18874 (57.0%) fathers smoked during pregnancy. During follow-up, 7825 incident cases of adult-onset hypertension were reported. Both maternal and paternal smoking of ≥ 15 cigarettes/d during pregnancy were associated with increased risks of hypertension (rate ratio, 1.19; 95% CI, 1.09-1.29; and rate ratio, 1.18; 95% CI, 1.12-1.25, respectively) in the age-adjusted models. Further adjustment for birth weight did not affect the effect estimates appreciably, whereas additional adjustment for body shape and weight until age 18, or current body mass index, attenuated the associations with both maternal and paternal smoking (rate ratio, 1.07; 95% CI, 0.98-1.16; and rate ratio, 1.06; 95% CI, 1.01-1.12, respectively). The associations of parental smoking during pregnancy with the risk of hypertension in the offspring were largely explained by body weight throughout life, suggesting that these associations may not reflect direct intrauterine mechanisms.

    Objectives Enzyme replacement therapy has shown to be effective for childhood/adult onset Pompe disease (AOPD). The discovery of biomarkers useful for monitoring disease progression is one of the priority research topics in Pompe disease. Muscle MRI could be one possible test but the correlation between muscle MRI and muscle strength and function has been only partially addressed so far. Methods We studied 34 AOPD patients using functional scales (Manual Research Council scale, hand held myometry, 6 minutes walking test, timed to up and go test, time to climb up and down 4 steps, time to walk 10 meters and Motor Function Measure 20 Scale), respiratory tests (Forced Vital Capacity seated and lying, Maximun Inspiratory Pressure and Maximum Expiratory Pressure), daily live activities scales (Activlim) and quality of life scales (Short Form-36 and Individualized Neuromuscular Quality of Life questionnaire). We performed a whole body muscle MRI using T1w and 3-point Dixon imaging centered on thighs and lower trunk region. Results T1w whole body muscle MRI showed a homogeneous pattern of muscle involvement that could also be found in pre-symptomatic individuals. We found a strong correlation between muscle strength, muscle functional scales and the degree of muscle fatty replacement in muscle MRI analyzed using T1w and 3-point Dixon imaging studies. Moreover, muscle MRI detected mild degree of fatty replacement in paraspinal muscles in pre-symptomatic patients. Conclusion Based on our findings, we consider that muscle MRI correlates with muscle function in patients with AOPD and could be useful for diagnosis and follow-up in pre-symptomatic and symptomatic patients under treatment. Take home message Muscle MRI correlates with muscle function in patients with AOPD and could be useful to follow-up patients in daily clinic. PMID:27711114

  15. Cleaning agents and asthma.

    PubMed

    Quirce, S; Barranco, P

    2010-01-01

    Although cleaners represent a significant part of the working population worldwide, they remain a relatively understudied occupational group. Epidemiological studies have shown an association between cleaning work and asthma, but the risk factors are uncertain. Cleaning workers are exposed to a large variety of cleaning products containing both irritants and sensitizers, as well as to common indoor allergens and pollutants. Thus, the onset or aggravation of asthma in this group could be related to an irritant-induced mechanism or to specific sensitization. The main sensitizers contained in cleaning products are disinfectants, quaternary ammonium compounds (such as benzalkonium chloride), amine compounds, and fragrances.The strongest airway irritants in cleaning products are bleach (sodium hypochlorite), hydrochloric acid, and alkaline agents (ammonia and sodium hydroxide), which are commonly mixed together. Exposure to the ingredients of cleaning products may give rise to both new-onset asthma, with or without a latency period, and work-exacerbated asthma. High-level exposure to irritants may induce reactive airways dysfunction syndrome. Cleaning workers may also have a greater relative risk of developing asthma due to prolonged low-to-moderate exposure to respiratory irritants. In addition, asthma-like symptoms without confirmed asthma are also common after exposure to cleaning agents. In many cleaners, airway symptoms induced by chemicals and odors cannot be explained by allergic or asthmatic reactions. These patients may have increased sensitivity to inhaled capsaicin, which is known to reflect sensory reactivity, and this condition is termed airway sensory hyperreactivity.

    Myofibroma is a rare benign neoplasm of myofibroblastic origin. It typically occurs in the skin and subcutaneous tissues of the head and neck in infants and young children as multicentric lesions known as infantile myofibromatosis. Intraosseous myofibromas are very rare and are typically destructive lesions that predominantly affect craniofacial bones in the setting of myofibromatosis. Solitary, intraosseous myofibromas in adults are exceedingly rare. Herein, we report a myofibroma involving the middle phalanx of the right index finger in a 58-year-old man who presented with a pathologic fracture. Twelve other cases of adult-onset, intraosseous myofibroma were compiled from the English language literature and integrated with this report.

    Studies on depression response to chronic pain are limited by lack of clarification of different forms of response patterns and cross-sectional measures. The current study examined heterogeneous long-term patterns of depression response to chronic pain onset using the mixture modeling technique. Depression symptoms prior to and following pain onset over a course of six years were charted in a nationally representative middle-aged sample. Four distinct depression symptom trajectories emerged. The resilience (72.0%) trajectory describes a pattern of no/minimal depression symptoms prior to and following pain onset. The post-pain depression trajectory (11.4%) describes a pattern of low depression at baseline and increasing symptoms following pain onset. The chronic depression (6.8%) trajectory is characterized by persistently high depression symptoms irrespective of pain onset. The prior depression improved (9.8%) trajectory describes a pattern of high depression at baseline and gradually declining symptoms following pain onset. Self-rated health at both baseline and following pain onset predicted the resilience trajectory. Baseline self-rated health distinguished the post-pain depression and chronic depression trajectories. Individuals in the prior depression improved trajectory were older and had more chronic illnesses at baseline but fewer illnesses following pain onset, compared to those in the resilience or post-pain depression trajectory.

    Occupational asthma is the most common form of occupational lung disease in the developed world at the present time. In this review, the epidemiology, pathogenesis/mechanisms, clinical presentations, management, and prevention of occupational asthma are discussed. The population attributable risk of asthma due to occupational exposures is considerable. Current understanding of the mechanisms by which many agents cause occupational asthma is limited, especially for low-molecular-weight sensitizers and irritants. The diagnosis of occupational asthma is generally established on the basis of a suggestive history of a temporal association between exposure and the onset of symptoms and objective evidence that these symptoms are related to airflow limitation. Early diagnosis, elimination of exposure to the responsible agent, and early use of inhaled steroids may play important roles in the prevention of long-term persistence of asthma. Persistent occupational asthma is often associated with substantial disability and consequent impacts on income and quality of life. Prevention of new cases is the best approach to reducing the burden of asthma attributable to occupational exposures. Future research needs are identified. PMID:10931788

    Background The combined impact of lifestyle factors on incidence of diabetes mellitus later in life is not well established. The objective of this study was to determine how lifestyle factors, assessed in combination, relate to new-onset diabetes in a broad and relatively unselected population of older adults. Methods We prospectively examined associations of lifestyle factors, measured using repeated assessments later in life, with incident diabetes mellitus during a 10-year period (1989–1998) among 4883 men and women 65 years or older (mean [SD] age at baseline, 73[6] years) enrolled in the Cardiovascular Health Study. Low-risk lifestyle groups were defined by physical activity level (leisure-time activity and walking pace) above the median; dietary score (higher fiber intake and polyunsaturated to saturated fat ratio, lower trans-fat intake and lower mean glycemic index) in the top 2 quintiles; never smoked or former smoker more than 20 years ago or for fewer than 5 pack-years; alcohol use (predominantly light or moderate); body mass index less than 25 (calculated as weight in kilograms divided by height in meters squared); and waist circumference of 88 cm for women or 92 cm for men. The main outcome measure was incident diabetes defined annually by new use of insulin or oral hypoglycemic medications. We also evaluated fasting and 2-hour postchallenge glucose levels. Results During 34 539 person-years, 337 new cases of drug-treated diabetes mellitus occurred (9.8 per 1000 person-years). After adjustment for age, sex, race, educational level, and annual income, each lifestyle factor was independently associated with incident diabetes.

  20. Mutation screen and association studies for the fatty acid amide hydrolase (FAAH) gene and early onset and adult obesity

    PubMed Central

    2010-01-01

    Background The orexigenic effects of cannabinoids are limited by activation of the endocannabinoid degrading enzyme fatty acid amide hydrolase (FAAH). The aim of this study was to analyse whether FAAH alleles are associated with early and late onset obesity. Methods We initially assessed association of five single nucleotide polymorphisms (SNPs) in FAAH with early onset extreme obesity in up to 521 German obese children and both parents. SNPs with nominal p-values ≤ 0.1 were subsequently analysed in 235 independent German obesity families. SNPs associated with childhood obesity (p-values ≤ 0.05) were further analysed in 8,491 adult individuals of a population-based cohort (KORA) for association with adult obesity. One SNP was further analysed in 985 German obese adults and 588 normal and underweight controls. In parallel, we screened the FAAH coding region for novel sequence variants in 92 extremely obese children using single-stranded-conformation-polymorphism-analysis and denaturing HPLC and assessed the implication of the identified new variants for childhood obesity. Results The trio analysis revealed some evidence for an association of three SNPs in FAAH (rs324420 rs324419 and rs873978) with childhood obesity (two-sided p-values between 0.06 and 0.10). Although analyses of these variants in 235 independent obesity families did not result in statistically significant effects (two-sided p-values between 0.14 and 0.75), the combined analysis of all 603 obesity families supported the idea of an association of two SNPs in FAAH (rs324420 and rs2295632) with early onset extreme obesity (p-values between 0.02 and 0.03). No association was, however, found between these variants and adult obesity. The mutation screen revealed four novel variants, which were not associated with early onset obesity (p > 0.05). Conclusions As we observed some evidence for an association of the FAAH variants rs2295632 rs324420 with early onset but not adult obesity, we conclude that the

    In California, 2.8 million children and adults (900,000 children and 1.9 million adults) suffer from active asthma. One out of six of these Californians (16%) lives below the poverty level. Low-income adults and children with active asthma disproportionately bear the burden of asthma. They experience more frequent symptoms, go to the emergency department (ED) more often for asthma care, miss more school and have poorer health status. They also are more likely to lack access to health care and to live in conditions associated with asthma exacerbations. Using data from the 2003 California Health Interview Survey (CHIS 2003), this policy brief examines the burden of asthma among low-income asthma sufferers as well as some opportunities to reduce the burden for these asthma sufferers. Active asthma refers to people who have been diagnosed with asthma and who reported they still have asthma and/or experienced an asthma attack in the past year.

    Calprotectin is a calcium-binding cytosolic protein, mainly expressed in immune cells, such as neutrophils, monocytes, and macrophages. Our study aimed to evaluate the diagnostic value of calprotectin for adult-onset Still's disease (AOSD), by comparing serum calprotectin concentrations in patients with AOSD (n = 46), rheumatoid arthritis (RA, n = 34), primary Sjögren syndrome (pSS, n = 40), systemic lupus erythematosus (SLE, n = 39), osteoarthritis (OA, n = 20), and healthy controls (HCs, n = 49). Calprotectin concentrations were significantly higher in patients with AOSD (55.26 ± 18.00 ng/ml), compared to patients with RA (39.17 ± 18.90 ng/ml), pSS (35.31 ± 19.47 ng/ml), SLE (32.21 ± 25.01 ng/ml), OA (19.24 ± 10.67 ng/ml), and HCs (8.46 ± 5.17 ng/ml). All the differences were highly significant (p < 0.001). Using receiver-operating characteristic curve, the cut-off value of calprotectin was defined as 45.488 ng/ml, and its sensitivity and specificity for AOSD diagnosis were 63.0 and 80.1%, respectively. The positive rate of calprotectin was significantly higher in AOSD cases compared to patients with other diseases and healthy controls (p < 0.001). Serum calprotectin was positively correlated with ferritin (r = 0.294, p < 0.05), and concentration of hemoglobin was significantly lower in calprotectin-positive patients compared to negative patients in AOSD (103.49 ± 20.21 g/l vs 115.71 ± 15.59 g/l, t = -2.142, p = 0.038). These findings suggest that serum calprotectin may serve as a promising marker for the diagnosis of AOSD and monitor disease activity to a certain extent.

    Background Palmitoleic acid (cis-16:1n-7), produced by endogenous fat synthesis, has been linked to both beneficial and deleterious metabolic effects, potentially confounded by diverse determinants and tissue sources of endogenous production. Trans-palmitoleate (trans-16:1n-7) represents a distinctly exogenous source of 16:1n-7, unconfounded by endogenous synthesis or its determinants, that may be uniquely informative. Objective We investigated whether circulating trans-palmitoleate was independently related to lower metabolic risk and incident type2 diabetes. Design Prospective cohort study (1992–2006). Setting Four US communities. Patients 3,736 adults in the Cardiovascular Health Study. Measurements Plasma phospholipid fatty acids, anthropometry, blood lipids, inflammatory markers, and glucose-insulin levels were measured at baseline in 1992; and diet, 3 years earlier. In multivariable-adjusted models, we investigated how demographic, clinical, and lifestyle factors independently related to trans-palmitoleate; how trans-palmitoleate related to major metabolic risk factors; and how trans-palmitoleate related to new-onset diabetes (304 incident cases). We validated findings for metabolic risk factors in an independent cohort of 327 women. Results In multivariable-analyses, whole-fat dairy consumption was most strongly associated with higher trans-palmitoleate. Higher trans-palmitoleate was associated with slightly lower adiposity and, independently, higher high-density-lipoprotein(HDL)-cholesterol (across quintiles: +1.9%, P=0.04), lower triglycerides (−19.0%, P<0.001), lower total:HDL-cholesterol (−4.7%, P<0.001), lower C-reactive protein (−13.8%, P=0.05), and lower insulin resistance (−16.7%, P<0.001). Trans-palmitoleate was associated with substantially lower incidence of diabetes, with multivariable-hazard-ratios=0.41 (95%CI=0.27–0.64) and 0.38 (95%CI=0.24–0.62) in quintile-4 and quintile-5, versus quintile-1 (P-trend<0.001).

    The breakdown of immune tolerance against islet antigens causes type 1 diabetes (T1D). The antigens associated with adult-onset T1D (AT1D) remain largely undefined. It is possible that AT1D patients display a unique type of CD4(+) T cells specific for a certain islet antigen. Here we analyzed the cytokine production profiles of CD4(+) helper T (Th) cells that are specific for three islet antigens; GAD65, preproinsulin, and IGRP in patients with AT1D, juvenile-onset T1D (JT1D), and age-, gender- and human leukocyte antigen (HLA)-matched control adults. While IGRP-specific Th cells in AT1D patients were dominantly Th1 cells, IGRP-specific Th cells in control adults and JT1D patients were dominantly Th2 and T regulatory type 1 (Tr1) cells. Notably, the frequency of IGRP-specific Tr1 cells was significantly lower in AT1D patients than in control adults and JT1D patients. In conclusion, our study suggests that IGRP-specific Th cells play a unique pathogenic role in AT1D.

    Domestic dogs can suffer from hearing losses that can have profound impacts on working ability and quality of life. We have identified a type of adult-onset hearing loss in Border Collies that appears to have a genetic cause, with an earlier age of onset (3-5 years) than typically expected for aging dogs (8-10 years). Studying this complex trait within pure breeds of dog may greatly increase our ability to identify genomic regions associated with risk of hearing impairment in dogs and in humans. We performed a genome-wide association study (GWAS) to detect loci underlying adult-onset deafness in a sample of 20 affected and 28 control Border Collies. We identified a region on canine chromosome 6 that demonstrates extended support for association surrounding SNP Chr6.25819273 (p-value = 1.09 × 10(-13)). To further localize disease-associated variants, targeted next-generation sequencing (NGS) of one affected and two unaffected dogs was performed. Through additional validation based on targeted genotyping of additional cases (n = 23 total) and controls (n = 101 total) and an independent replication cohort of 16 cases and 265 controls, we identified variants in USP31 that were strongly associated with adult-onset deafness in Border Collies, suggesting the involvement of the NF-κB pathway. We found additional support for involvement of RBBP6, which is critical for cochlear development. These findings highlight the utility of GWAS-guided fine-mapping of genetic loci using targeted NGS to study hereditary disorders of the domestic dog that may be analogous to human disorders.

    Background Leukotriene receptor antagonists (LTRAs) are recommended as alternative treatment in patients with mild asthma, but their effect compared with placebo is unclear. Purpose To determine the benefits and harms of LTRAs as monotherapy or in combination with inhaled corticosteroids compared with placebo in adults and adolescents with asthma. Data sources MEDLINE and the Cochrane Central Register of Controlled Trials from inception through June 2015. Study selection Peer-reviewed, English-language, randomized controlled trials in patients with asthma that reported the effect of LTRAs versus placebo on measures of asthma control. Data extraction Three researchers extracted data on the study population, interventions, outcome measures, adverse events, and study methodology were extracted in duplicate. Data synthesis Of 2008 abstracts screened, 50 trials met eligibility criteria. Random-effects meta-analyses and meta-regression were performed. In six trials of LTRA monotherapy, LTRAs reduced the risk of an exacerbation (summary risk ratio [RR] = 0.60, 95% CI 0.44, 0.81). In four trials of LTRA as an add-on to inhaled corticosteroids, the summary RR for exacerbation was 0.80 (95% CI: 0.60, 1.07). LTRAs significantly increased FEV1 either as monotherapy or as add-on to inhaled corticosteroids, whereas FEV1 % predicted was only improved in trials of LTRA monotherapy. Adverse event rates were similar in the intervention and comparator groups. Limitations Variation in definitions and reporting of outcomes, high risk of bias, heterogeneity, and possible selective outcome reporting bias. Conclusions LTRAs as monotherapy improved asthma control compared to placebo. It remains unclear however, which patients with asthma are more likely to respond to treatment with LTRAs. PMID:26390230

    Asthma and obesity are epidemiologically linked; however, similar relationships are also observed with other markers of the metabolic syndrome, such as insulin resistance and dyslipidemia, which cannot be accounted for by increased body mass alone. Obesity appears to be a predisposing factor for the asthma onset, both in adults and in children. In addition, obesity could make asthma more difficult to control and to treat. Although obesity may predispose to increased Th2 inflammation or tendency to atopy, other mechanisms need to be considered, such as those mediated by hyperglycaemia, hyperinsulinemia and dyslipidemia in the context of metabolic syndrome. The mechanisms underlying the association between asthma and metabolic syndrome are yet to be determined. In the past, these two conditions were believed to occur in the same individual without any pathogenetic link. However, the improvement in asthma symptoms following weight reduction indicates a causal relationship. The interplay between these two diseases is probably due to a bidirectional interaction. The purpose of this review is to describe the current knowledge about the possible link between metabolic syndrome and asthma, and explore potential application for future studies and strategic approaches.

    Occupational asthma belongs to communicable diseases, which should be reported in Hungary. During a 24-year period between January 1990 and December 2013, 180 occupational asthma cases were reported in Hungary (52 cases between 1990 and 1995, 83 cases between 1996 and 2000, 40 cases between 2001 and 2006, and 5 cases between 2007 and 2013). These data are unusual, because according to the official report of the National Korányi Pulmonology Institute in Budapest, at least 14,000 new adult asthma cases were reported in every year between 2000 and 2012 in Hungary. Also, international data indicate that at least 2% of adult patients with asthma have occupational asthma and at least 50 out of 1 million employees develop occupational asthma in each year. In 2003, 631 new occupational asthma patients were reported in the United Kingdom, but only 7 cases in Hungary. Because it is unlikely that the occupational environment in Hungary is much better than anywhere else in the world, it seems that not all new occupational asthma cases are reported in Hungary. Of the 180 reported cases in Hungary, 55 were bakers or other workers in flour mills. There were 11 metal-workers, 10 health care assistants, 9 workers dealing with textiles (tailors, dressmakers, workers in textile industry) and 9 employees worked upon leather and animal fur. According to international data, the most unsafe profession is the animal keeper in scientific laboratories, but only 4 of them were reported as having occupational asthma during the studied 24 years in Hungary. Interestingly, 3 museologists with newly-diagnosed occupational asthma were reported in 2003, but not such cases occurred before or after that year. In this paper the Hungarian literature of occupational asthma is summarized, followed by a review on the classification, pathomechanism, clinical presentation, predisposing factors, diagnostics and therapeutic aspects of the disease.

    Links between environmental chemicals and human health have emerged over the last few decades, but the effects from polyaromatic hydrocarbons were less studied, compared to other commonly known environmental chemicals such as heavy metals, phthalates, arsenic, phenols, pesticides, etc. Therefore, the aim of the study was to examine the relationships of urinary polyaromatic hydrocarbons and adult respiratory health conditions using a large human sample in a national and population-based setting in recent years. Data were retrieved from United States National Health and Nutrition Examination Surveys, 2011-2012 including demographics, self-reported health conditions, and urinary polyaromatic hydrocarbons. Statistical analyses including chi-square test, t test, and survey-weighted logistic regression modeling were performed. Of 5560 American adults aged 20-80, urinary 2-hydroxyfluorene and 3-hydroxyfluorene were positively associated with emphysema (OR, 1.60, 95 % CI 1.26 to 2.03, P = 0.001 and OR, 1.42, 95 % CI 1.15 to 1.77, P = 0.003, respectively) and chronic bronchitis (OR, 1.42, 95 % CI 1.04 to 1.94, P = 0.031 and OR, 1.40, 95 % CI 1.03 to 1.91, P = 0.036, respectively), while 2-hydroxynaphthalene (2-naphthol) was likely to be borderline associated with emphysema and chronic bronchitis. Conversely, urinary 1-hydroxyphenanthrene, 3-hydroxyphenanthrene, 1-hydroxypyrene, and 4-hydroxyphenanthrene were inversely associated with asthma and infections. Urinary polyaromatic hydrocarbons are associated with adult respiratory health conditions, although the causality cannot be established. For future research, studies using large human sample across regions to longitudinally monitor would be suggested. For practice and policy-making, regulation on minimizing polyaromatic hydrocarbons exposure to protect respiratory health might need to be considered in future health and environmental policies and intervention programs.

    Epstein-Barr virus (EBV) has been implicated in the pathogenesis of multiple sclerosis (MS). Recent reports proposed an increased EBV-targeted humoral immune response in MS, which appears to be more pronounced in pediatric patients. However, little is known about the CNS-derived antibody production against EBV in patients with MS. The objective of this study was to assess the frequency and intensity of intrathecal antibody production against EBV as compared to other neurotropic viruses in pediatric and adult onset MS. In cohorts of 43 childhood, 50 adult onset MS patients, 20 children and 12 adults with other CNS disorders, paired CSF and serum samples were studied. Frequency and intensity of intrathecal antibody production against EBV as compared to measles, rubella, varicella zoster (VZV) and herpes simplex virus (HSV) were analyzed by determination of virus-specific CSF-to-serum Antibody Indices (AI). Intrathecally synthesized EBV antibodies were detectable in 26% pediatric and 10% adult onset MS patients, compared to frequencies ranging in both groups from 10 to 60% for the other viruses. Median AIs for EBV were lower than those for all other viruses, with more than twofold higher median AI for measles, rubella and VZV. The EBV-targeted humoral immune response in the CNS is only part of the intrathecal polyspecific antibody production in MS, directed against various neurotropic viruses. Our results do not rule out the possibility that EBV is involved in the pathogenesis of MS by triggering diverse cellular immune mechanisms, but they argue against a direct pathogenic role of EBV-targeted humoral immune response within the CNS.

    The incidence of adult-onset T1D in low-risk non-HLA type has increased several folds, whereas the contemporaneous incidence in high-risk HLA-type remains stable. Various factors behind this selective increase in T1D in young adults remain unclear. Obesity and its associated abnormalities appear to be an important determinant; however, the underlying mechanism involved is not understood. Recently, we have developed two novel transgenic obese mice models, Mito-Ob and m-Mito-Ob, by expressing a pleiotropic protein prohibitin (PHB) and a phospho mutant form of PHB (Y114F-PHB or m-PHB) from the aP2 gene promoter, respectively. Both mice models develop obesity in a sex-neutral manner, independent of diet; but obesity associated chronic low-grade inflammation and insulin resistance in a male sex-specific manner. Interestingly, on a high fat diet (HFD) only male m-Mito-Ob mice displayed marked mononuclear cell infiltration in pancreas and developed insulitis that mimic adult-onset T1D. Male Mito-Ob mice that share the metabolic phenotype of male m-Mito-Ob mice, and female m-Mito-Ob that harbor m-PHB similar to male m-Mito-Ob mice, did not develop insulitis. Thus, insulitis development in male m-Mito-Ob in response to HFD requires both, obesity-related abnormalities and m-PHB. Collectively, this data provides a proof-of-concept that obesity-associated abnormalities couple environmental triggers with genetic susceptibility in adult-onset T1D and reveals PHB as a potential susceptibility gene for T1D.

    Prenatal maternal infection contributes to the etiology of schizophrenia, with D-serine, an endogenous co-agonist of the N-methyl-D-aspartate (NMDA) receptor, playing a role in the pathophysiology of this disease. We examined whether supplementation with D-serine during juvenile and adolescent stages could prevent the onset of cognitive deficits, prodromal and the core symptoms of schizophrenia in adult offspring after maternal immune activation (MIA). Juvenile offspring exposed prenatally to poly(I:C) showed reduced expression of NMDA receptor subunits in the hippocampus. Supplementing drinking water with D-serine (600 mg/L from P28 to P56) prevented the onset of cognitive deficits in adult offspring after MIA, in a significant manner. This study shows that supplementing offspring with D-serine during juvenile and adolescent stages could prevent the onset of psychosis in adulthood, after MIA. Therefore, early intervention with D-serine may prevent the occurrence of psychosis in high-risk subjects. PMID:27853241

    Although biomarker studies of late-onset Alzheimer's disease suggest pathology to be present decades before diagnosis, little is known about cognitive performance at this stage. A sample of 210 adults (aged 40-59) of whom 103 have a parent diagnosed with dementia (family history subgroup) underwent computerized cognitive testing. ApoE status was determined, and 193 subjects had magnetic resonance imaging. Distance from dementia onset was estimated in relation to age of parental diagnosis, and Cardiovascular Risk Factors, Aging, and Incidence of Dementia Risk Scores were calculated. Lower hippocampal volumes (P = .04) were associated with poorer spatial location recall and higher Dementia Risk Scores with poorer visual recognition (P = .0005), and lower brain and hippocampal volume (P < .0001, P = .04, respectively). Family history subgroup participants closer to dementia onset had lower scores on visual working memory (P = .05), whereas those with an ApoE ε4 allele performed better on form perception (P = .005). Middle-aged adults at risk of dementia show evidence of poorer cognitive performance, principally in visuospatial functions.

    Work-related asthma is asthma that is caused or exacerbated by exposure to specific substances in the workplace. Approximately 10%-16% of adult-onset asthma cases are attributable to occupational factors, and estimates of asthma exacerbated by work range from 13% to 58%. During 2008-2012, the Massachusetts Department of Public Health received nine reports of work-related asthma among workers at a facility that manufactured syntactic foam used for flotation in the offshore oil and gas industry. These reports and a request from facility employees led to a CDC health hazard evaluation during 2012-2013 in which CDC reviewed records, toured the facility, and administered a questionnaire to current employees. Investigators found that workers' risk for asthma increased substantially after hire, possibly because of known asthma triggers (i.e., asthmagens) used in production. The company has since initiated efforts to reduce employee exposures to these substances. This cluster of work-related asthma was identified through CDC-funded, state-based surveillance and demonstrates complementary state and federal investigations.

  17. Epidemiologic evidence for asthma and exposure to air toxics: linkages between occupational, indoor, and community air pollution research.

    PubMed Central

    Delfino, Ralph J

    2002-01-01

    Outdoor ambient air pollutant exposures in communities are relevant to the acute exacerbation and possibly the onset of asthma. However, the complexity of pollutant mixtures and etiologic heterogeneity of asthma has made it difficult to identify causal components in those mixtures. Occupational exposures associated with asthma may yield clues to causal components in ambient air pollution because such exposures are often identifiable as single-chemical agents (e.g., metal compounds). However, translating occupational to community exposure-response relationships is limited. Of the air toxics found to cause occupational asthma, only formaldehyde has been frequently investigated in epidemiologic studies of allergic respiratory responses to indoor air, where general consistency can be shown despite lower ambient exposures. The specific volatile organic compounds (VOCs) identified in association with occupational asthma are generally not the same as those in studies showing respiratory effects of VOC mixtures on nonoccupational adult and pediatric asthma. In addition, experimental evidence indicates that airborne polycyclic aromatic hydrocarbon (PAH) exposures linked to diesel exhaust particles (DEPs) have proinflammatory effects on airways, but there is insufficient supporting evidence from the occupational literature of effects of DEPs on asthma or lung function. In contrast, nonoccupational epidemiologic studies have frequently shown associations between allergic responses or asthma with exposures to ambient air pollutant mixtures with PAH components, including black smoke, high home or school traffic density (particularly truck traffic), and environmental tobacco smoke. Other particle-phase and gaseous co-pollutants are likely causal in these associations as well. Epidemiologic research on the relationship of both asthma onset and exacerbation to air pollution is needed to disentangle effects of air toxics from monitored criteria air pollutants such as particle mass

    PubMed

    Taylor, Philip E; Jonsson, Haflidi

    2004-09-01

    Thunderstorms have often been linked to epidemics of asthma, especially during the grass flowering season; however, the precise mechanisms explaining this phenomenon are unknown. Evidence of high respirable allergen loadings in the air associated with specific meteorologic events combined with an analysis of pollen physiology suggests that rupture of airborne pollen can occur. Strong downdrafts and dry, cold outflows distinguish thunderstorm rain from frontal rain. The weather system of a mature thunderstorm likely entrains grass pollen into the cloud base, where pollen rupture would be enhanced, then transports the respirable-sized fragments of pollen debris to ground level where outflows distribute them ahead of the rain. The conditions occurring at the onset of a thunderstorm might expose susceptible people to a rapid increase in concentrations of pollen allergens in the air that can readily deposit in the lower airways and initiate asthmatic reactions.

    The newly published Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) elevates the threshold of the ADHD age-of-onset criterion from 7 to 12 years. This study evaluated the quality of life and functional impairment of adults with ADHD who had symptoms onset by or after 7 years and examined the mediation effect of family function and anxiety/depression symptoms between ADHD diagnosis and quality of life and functional impairment. We assessed 189 adults with ADHD and 153 non-ADHD controls by psychiatric interview and self-administered reports on the Adult ADHD Quality of Life Scale, Weiss Functional Impairment Rating Scale, Family APGAR, and Adult Self Report Inventory-4. The ADHD group was divided into early-onset ADHD (onset <7 years, n=147) and late-onset ADHD (onset between 7 and 12 years, n=42). The mediation analysis was conducted to verify the mediating factors from ADHD to functional impairment and quality of life. The late-onset ADHD had more severe functional impairment at work and poorer family support than early-onset ADHD while they had comparable impairment at other domains. Less perceived family support and current anxiety/depressive symptoms partially mediated the link between ADHD diagnosis and quality of life/functional impairment both in early- and late-onset ADHD. Our data support decreased quality of life and increased functional impairment in adult ADHD, regardless of age of onset, and these adverse outcomes may be mediated by family support and anxiety/depression at adulthood. Our findings also imply that the new DSM-5 ADHD criteria do not over-include individuals without impairment.

    Tauopathy in the hippocampus is one of the earliest cardinal features of Alzheimer's disease (AD), a condition characterized by progressive memory impairments. In fact, density of tau neurofibrillary tangles (NFTs) in the hippocampus strongly correlates with severity of cognitive impairments in AD. In the present study, we employed a somatic cell gene transfer technique to create a rodent model of tauopathy by injecting a recombinant adeno-associated viral vector with a mutated human tau gene (P301L) into the hippocampus of adult rats. The P301L mutation is causal for frontotemporal dementia with parkinsonism-17 (FTDP-17), but it has been used for studying memory effects characteristic of AD in transgenic mice. To ascertain if P301L-induced mnemonic deficits are persistent, animals were tested for 6 months. It was hypothesized that adult-onset, spatially restricted tau expression in the hippocampus would produce progressive spatial working memory deficits on a learned alternation task. Rats injected with the tau vector exhibited persistent impairments on the hippocampal-dependent task beginning at about 6 weeks post-transduction compared to rats injected with a green fluorescent protein vector. Histological analysis of brains for expression of human tau revealed hyperphosphorylated human tau and NFTs in the hippocampus in experimental animals only. Thus, adult-onset, vector-induced tauopathy spatially restricted to the hippocampus progressively impaired spatial working memory in rats. We conclude that the model faithfully reproduces histological and behavioral findings characteristic of dementing tauopathies. The rapid onset of sustained memory impairment establishes a preclinical model particularly suited to the development of potential tauopathy therapeutics.

    A 65-year-old woman with progressive muscle weakness and a diffuse rash of three years' duration was examined. Muscle tissue was studied with histochemical techniques, phase-contrast microscopy, electron microscopy, and two-dimensional electrophoresis. Histochemical studies showed numerous nemaline rods, with a normal ratio of types I and II fibers. Two-dimensional electrophoresis revealed abnormalities in the myosin light chain and tropomyosin protein patterns when compared with normal and diseased muscle biopsy samples, including those from two patients with adult-onset dermatomyositis.

    The goal of predictive testing is to modify the risk for currently healthy individuals to develop a genetic disease in the future. Such testing using polymorphic DNA markers has had major application in Huntington disease. The Canadian Collaborative Study of Predictive Testing for Huntington Disease has been guided by major principles of medical ethics, including autonomy, beneficence, confidentiality, and justice. Numerous ethical and legal dilemmas have arisen in this program, challenging these principles and occasionally casting them into conflict. The present report describes these dilemmas and offers our approach to resolving them. These issues will have relevance to predictive-testing programs for other adult-onset disorders. PMID:1971997

    Pericardial effusion is caused by various pathological agents. In differential diagnosis infectious as well as non-infectious factors have to be considered. Adult-onset Still disease (AOSD)--relatively uncommon systemic inflammatory disorder of unknown etiology--is among possible diagnosis. The disease typically affects patients in the age between 16-35 years and is characterized by spiking fever, arthralgia, evanescent salmon rash with other abnormalities including pharingitis, serositis (especially pleuritis and pericarditis) and leucocytosis as well as increased serum levels of inflammatory indicators. We present two patients with recurrent pericardial effusion in the course of AOSD.

    Many Californians with asthma are exposed to environmental conditions in the home-such as the presence of tobacco smoke and furry pets-which can trigger asthma symptoms. In addition, many who have not been diagnosed with asthma experience asthma-like breathing problems when exposed to these same indoor conditions. Nearly 1.9 million California adults and 890,000 children have active asthma (7.3% of all adults and 10.4% of all children). Among those with active asthma, 970,000 adults and 300,000 children suffered from symptoms at least monthly in 2003. An additional 2.6 million California adults and 810,000 children who had not been diagnosed with asthma suffered from asthma-like symptoms such as wheezing in 2003 (11.1% of all adults and 9.3% of all children). A Publication of the UCLA Center for Health Policy Research Using results from the 2003 California Health Interview Survey (CHIS 2003), this policy brief examines the association of asthma symptoms and asthma-like breathing problems with smoking and the presence of tobacco smoke in the home, and with the presence of dogs and cats in the home. This brief presents the prevalence of monthly asthma symptoms among adults and children with active asthma and the prevalence of wheezing and other asthma-like symptoms in the previous year among those not diagnosed with asthma. Active asthma refers to being diagnosed with asthma and also reporting that one still has asthma and/or that one experienced an asthma attack in the past year. There are a number of known environmental triggers in the home, including environmental tobacco smoke, animal dander, dust mites, cockroaches, molds and pollens. This brief discusses those triggers for which CHIS 2003 collected useful data. Other triggers have also been found to significantly contribute to breathing problems.

    Objective To characterize work-related asthma by gender. Methods We analyzed state-based sentinel surveillance data on confirmed work-related asthma cases collected from California, Massachusetts, Michigan, and New Jersey during 1993–2008. We used Chi-square and Fisher’s Exact Test statistics to compare select characteristics between females and males. Results Of the 8239 confirmed work-related asthma cases, 60% were female. When compared to males with work-related asthma, females with work-related asthma were more likely to be identified through workers’ compensation (14.8% versus 10.6%) and less likely to be identified through hospital data (14.2% versus 16.9%). Moreover, when compared to males, females were more likely to have work-aggravated asthma (24.4% versus 13.5%) and less likely to have new-onset asthma (48.0% versus 56.5%). Females were also more likely than males with work-related asthma to work in healthcare and social assistance (28.7% versus 5.2%), educational services (11.8% versus 4.2%), and retail trade (5.0% versus 3.9%) industries and in office and administrative support (20.0% versus 4.0%), healthcare practitioners and technical (13.4% versus 1.6%), and education training and library (6.2% versus 1.3%) occupations. Agent groups most frequently associated with work-related asthma were miscellaneous chemicals (20.3%), cleaning materials (15.3%), and indoor air pollutants (14.9%) in females and miscellaneous chemicals (15.7%), mineral and inorganic dusts (13.2%), and pyrolysis products (12.7%) in males. Conclusions Among adults with work-related asthma, males and females differ in terms of workplace exposures, occupations, and industries. Physicians should consider these gender differences when diagnosing and treating asthma in working adults. PMID:24673105

    2017-01-01

    Adult onset Still’s disease is uncommon in middle-aged and elderly individuals and can rarely present with shock; shock is usually associated with disseminated intravascular coagulation, multiorgan dysfunction syndrome or acute respiratory distress syndrome. We report a post-menopausal woman with arthritis, fever, pneumonitis and hypotension which was managed as septic shock. Steroids were inadvertently missed during the second day of hospitalization in the intensive care unit. Persistence of hypotension on inotropes, with normal renal, hepatic and neurological function and recurrence of fever when steroids were skipped, led to suspicion of an inflammatory disorder. A diagnosis of Still’s disease may be entertained in postmenopausal women with polyarthritis, rash, and fever with leukocytosis. Sepsis is mimicked, and multiple antibiotics use is common before the diagnosis of such an entity is made. Shock is rare in adult onset Still’s disease and is not necessarily associated with disseminated intravascular coagulation, acute respiratory distress syndrome, or multiorgan dysfunction.

    Although adult-onset hypothyroidism (AOH) has been connected to neural activity alterations, including movement, behavioral, and mental dysfunctions, the underlying changes in brain metabolic physiology have not been investigated in a systemic and systematic way. The current knowledge remains fragmented, referring to different experimental setups and recovered from various brain regions. In this study, we developed and applied a gas chromatography-mass spectrometry (GC-MS) metabolomics protocol to obtain a holistic view of the cerebellar metabolic physiology in a Balb/cJ mouse model of prolonged adult-onset hypothyroidism induced by a 64-day treatment with 1% potassium perchlorate in the drinking water of the animals. The high-throughput analysis enabled the correlation between multiple parallel-occurring metabolic phenomena; some have been previously related to AOH, while others implicated new pathways, designating new directions for further research. Specifically, an overall decline in the metabolic activity of the hypothyroid compared to the euthyroid cerebellum was observed, characteristically manifested in energy metabolism, glutamate/glutamine metabolism, osmolytic/antioxidant capacity, and protein/lipid synthesis. These alterations provide strong evidence that the mammalian cerebellum is metabolically responsive to AOH. In light of the cerebellum core functions and its increasingly recognized role in neurocognition, these findings further support the known phenotypic manifestations of AOH into movement and cognitive dysfunctions.

    Patient: Female, 53 Final Diagnosis: Adult-onset Still’s Disease Symptoms: Abdominal pain • fever Medication: — Clinical Procedure: — Specialty: Rheumatology Objective: Rare disease Background: Adult-onset Still’s Disease (AOSD) is a rare systemic inflammatory disease accompanied by a triad of spiking fever, maculopapular exanthema, and arthralgia. To date, there is no definite laboratory or imaging test available for diagnosing AOSD, and the diagnosis is one of exclusion, which can be very challenging. Case Report: We report on the case of a 53-year-old female who presented with fever, arthralgia, and abdominal pain. Her initial laboratory tests showed elevated AST and ALT, and normal leukocytes with bandemia. During her hospitalization, we evaluated the patient for other potential differential diagnoses. After an extensive workup, the patient was diagnosed with AOSD based on Yamaguchi criteria. Her serum ferritin levels were measured and found to be markedly elevated, which is a non-specific finding in AOSD patients. Conclusions: This case highlights the important role of a detailed history and physical examination for timely diagnosis of AOSD to prevent complications and improve patient’s prognosis.

    The objective of this work is to report on a series of five patients with adult-onset leukoencephalopathy with neuroaxonal spheroids and pigmented glia (ALSP). ALSP is a rare adult-onset leukodystrophy, which encompasses hereditary diffuse leukoencephalopathy with axonal spheroids and pigmentary orthochromatic leukodystrophy. This was a retrospective chart review and literature review. Five previously healthy women presented with a rapidly progressive neurological disorder at ages 39, 37, 40, 30, and 47, respectively. All five individuals were initially diagnosed as suffering from multiple sclerosis. The clinical courses of the five patients were dominated by progressive spastic quadriparesis (patient 5, newly diagnosed, has paraparesis at this time) and dementia. Brain magnetic resonance imaging (MRI) showed diffuse cerebral atrophy, corpus callosal atrophy, and diffuse T2 hyperintensities in the subcortical and periventricular white matter with no gadolinium enhancing lesions. Three patients showed involvement of pyramidal tracts from motor cortex to the brainstem. Cerebrospinal fluid was normal in all cases. Diagnosis of ALSP was established by biopsy (two cases) and autopsy (two cases). Histopathology showed the presence of neuroaxonal spheroids in all four cases and pigmented glia in three. In the fifth case, diagnosis was established by genetic analysis alone that showed a disease-causing mutation in the colony-stimulating factor 1 receptor (CSF1R) gene. Genetic analysis was done in three patients with available DNA, and identified the disease-causing mutation in all three, including a novel mutation F828S. ALSP may be suspected in adults with rapid to subacute progression of neurological disease when (1) MRI shows corpus callosal atrophy on a background of generalized brain atrophy and diffuse white matter disease without postcontrast enhancement, (2) CSF studies are normal, and (3) studies for systemic inflammatory diseases and specific leukodystrophies are

  16. Does Inflammation Mediate Relationships Between Racial Identity and Onset of Menopause Among US Adults?

    2016-12-06

    We assess how well differences in ethnoracial background may predict timing of menopause among females in the USA and whether or not inflammatory biomarker levels appear to mediate these overall associations. We use data from the National Social Life, Health, and Aging Project (NSHAP) to model apparent net effects from race on menopausal onset, as well as possible mediating influences from the inflammatory biomarker C-reactive protein (CRP). Using continuous time event history analysis, we assess and frame overall relationships between race and menopausal age. We use structural equation modeling to assess potential mediating effects from CRP and to estimate direct and indirect components of these apparent effects. Our findings suggest that on average, black females experience menopause earlier than their peers of other racial backgrounds, and have higher inflammatory biomarker levels. Both black race and higher CRP have negative and significant direct associations with menopausal age. CRP appears to partially mediate the overall association between black race and earlier menopause. This apparent mediation persists with statistical controls for income, education, and body mass index. Our study concludes with recommendations for future research on racial identity, inflammation, and menopausal onset. We focus our recommendations on intersectional forms of inequality that may affect black females in later life.

    The purpose of this study was to evaluate the effects of early-life exercise on adult physical activity (wheel running, home-cage activity), body mass, food consumption, and circulating leptin levels in males from four replicate lines of mice selectively bred for high voluntary wheel running (High Runner or HR) and their four non-selected control (C) lines. Half of the mice were given wheel access shortly after weaning for three consecutive weeks. Wheel access was then removed for 52 days, followed by two weeks of adult wheel access for all mice. A blood sample taken prior to adult wheel testing was analyzed for circulating leptin concentration. Early-life wheel access significantly increased adult voluntary exercise on wheels during the first week of the second period of wheel access, for both HR and C mice, and HR ran more than C mice. During this same time period, activity in the home cages was not affected by early-age wheel access, and did not differ statistically between HR and C mice. Throughout the study, all mice with early wheel access had lower body masses than their sedentary counterparts, and HR mice had lower body masses than C mice. With wheel access, HR mice also ate significantly more than C mice. Early-life wheel access increased plasma leptin levels (adjusted statistically for fat-pad mass as a covariate) in C mice, but decreased them in HR mice. At sacrifice, early-life exercise had no statistically significant effects on visceral fat pad, heart (ventricle), liver or spleen masses (all adjusted statistically for variation in body mass). Results support the hypothesis that early-age exercise in mice can have at least transitory positive effects on adult levels of voluntary exercise, in addition to reducing body mass, and may be relevant for the public policy debates concerning the importance of physical education for children.

    A 21-year old male presented with ataxia and dysarthria that had appeared over a period of months. Exome sequencing identified a de novo missense variant in ATP1A3, the gene encoding the α3 subunit of Na,K-ATPase. Several lines of evidence suggest that the variant is causative. ATP1A3 mutations can cause rapid-onset dystonia-parkinsonism (RDP) with a similar age and speed of onset, as well as severe diseases of infancy. The patient’s ATP1A3 p.Gly316Ser mutation was validated in the laboratory by the impaired ability of the expressed protein to support the growth of cultured cells. In a crystal structure of Na,K-ATPase, the mutated amino acid was directly apposed to a different amino acid mutated in RDP. Clinical evaluation showed that the patient had many characteristics of RDP, however he had minimal fixed dystonia, a defining symptom of RDP. Successive magnetic resonance imaging (MRI) revealed progressive cerebellar atrophy, explaining the ataxia. The absence of dystonia in the presence of other RDP symptoms corroborates other evidence that the cerebellum contributes importantly to dystonia pathophysiology. We discuss the possibility that a second de novo variant, in ubiquilin 4 (UBQLN4), a ubiquitin pathway component, contributed to the cerebellar neurodegenerative phenotype and differentiated the disease from other manifestations of ATP1A3 mutations. We also show that a homozygous variant in GPRIN1 (G protein-regulated inducer of neurite outgrowth 1) deletes a motif with multiple copies and is unlikely to be causative. PMID:26990090

    Cystic hygroma is a benign congenital malformation of the lymphatic system that occurs in infant or children younger than 2 years of age. Although cystic hygroma is well recognized in pediatric practice, it seldom presents de novo in adulthood. These are commonly present in head and neck but can be present anywhere. Cystic hygroma is very rare in adults, but it should be considered in the differential diagnosis of adult neck swellings. Patients presenting with a painless, soft, fluctuant, and enlarging neck mass should have a careful history and physical examination along with radiological imaging to assist with diagnosis. Surgical intervention is the treatment of choice for this rare condition. Here, we are reporting a case of cystic hygroma in a 32-year-old male patient in the neck region. The objectives of this case report are to discuss the clinical presentation, diagnosis, histopathological findings and management of this malformation. PMID:27134456

    In the Swedish Building Energy, Technical Status and Indoor environment study, a total of 1160 adults from 605 single-family houses answered a questionnaire on respiratory health. Building inspectors investigated the homes and measured temperature, air humidity, air exchange rate, and wood moisture content (in attic and crawl space). Moisture load was calculated as the difference between indoor and outdoor absolute humidity. Totally, 7.3% were smokers, 8.7% had doctor' diagnosed asthma, 11.2% current wheeze, and 9.5% current asthma symptoms. Totally, 50.3% had respiratory infections and 26.0% rhinitis. The mean air exchange rate was 0.36/h, and the mean moisture load 1.70 g/m(3) . Damp foundation (OR=1.79, 95% CI 1.16-2.78) was positively associated while floor constructions with crawl space (OR=0.49, 95% CI 0.29-0.84) was negatively associated with wheeze. Concrete slabs with overlying insulation (OR=2.21, 95% CI 1.24-3.92) and brick façade (OR=1.71, 95% CI 1.07-2.73) were associated with rhinitis. Moisture load was associated with respiratory infections (OR=1.21 per 1 g/m(3) , 95% CI 1.04-1.40) and rhinitis (OR=1.36 per 1 g/m(3) , 95% CI 1.02-1.83). Air exchange rate was associated with current asthma symptoms (OR=0.85 per 0.1/h, 95% CI 0.73-0.99). Living in homes with damp foundation, concrete slabs with overlying insulation, brick façade, low ventilation flow, and high moisture load are risk factors for asthma, rhinitis, and respiratory infections.

    Children with special health care needs born today have a 90% chance of surviving into adulthood, making their transition to adult systems of care an issue that will affect almost all physicians. However, many adult generalists and specialists are not familiar with the management of chronic diseases that begin in childhood. While the public health system has made transition to appropriate adult care a priority, and many specialty organizations have endorsed this concept, there are no published studies addressing how the concept of transition can be taught to medical students or residents. The authors describe a one-week course for medical students, begun in 2001 at their institution, that addresses the transition for youth with special health care needs, emphasizing patient and family-centered care, cultural competence, and decision making in end-of-life issues. Cystic fibrosis, a common genetic disease with increasing life expectancy, is used as the model for the course. Involvement of interdisciplinary faculty, interviews with youth with special health care needs and family caregivers, readings from academic and nonacademic literature, and group discussions are presented as teaching methods. Key insights based on experience with the course are the need to include the voices of patients and families, the use of faculty from various professions and specialties to model interdisciplinary care, and the insight that problems specific to transition offer into contemporary health care financing. Future studies should measure the impact of such courses on students' knowledge of transition issues, and determine essential information required for physicians in practice.

  8. Invisible Victims: Delayed Onset Depression among Adults with Same-Sex Parents

    The relationship of elevated depression risk recently discovered among adult persons raised by same-sex parents with possible precipitating conditions in childhood has not previously been acknowledged. This study tests whether such inattention is supportable. Logistic regression based risk ratios were estimated from longitudinal measures of mental health outcomes observed in three waves (at ages 15, 22, and 28) of the US National Survey of Adolescent to Adult Health (n = 15,701). At age 28, the adults raised by same-sex parents were at over twice the risk of depression (CES-D: risk ratio 2.6, 95% CI 1.4–4.6) as persons raised by man-woman parents. These findings should be interpreted with caution. Elevated risk was associated with imbalanced parental closeness and parental child abuse in family of origin; depression, suicidality, and anxiety at age 15; and stigma and obesity. More research and policy attention to potentially problematic conditions for children with same-sex parents appears warranted. PMID:27313882

    Adult-onset Still's disease (AOSD) is often refractory to standard therapy. Anakinra (ANK), an interleukin-1 receptor antagonist, has demonstrated efficacy in single cases and small series of AOSD. We assessed the efficacy of ANK in a series of AOSD patients. Multicenter retrospective open-label study. ANK was used due to lack of efficacy to standard synthetic immunosuppressive drugs and in some cases also to at least 1 biologic agent. Forty-one patients (26 women/15 men) were recruited. They had a mean age of 34.4 ± 14 years and a median [interquartile range (IQR)] AOSD duration of 3.5 [2-6] years before ANK onset. At that time the most common clinical features were joint manifestations 87.8%, fever 78%, and cutaneous rash 58.5%. ANK yielded rapid and maintained clinical and laboratory improvement. After 1 year of therapy, the frequency of joint and cutaneous manifestations had decreased to 41.5% and to 7.3% respectively, fever from 78% to 14.6%, anemia from 56.1% to 9.8%, and lymphadenopathy from 26.8% to 4.9%. A dramatic improvement of laboratory parameters was also achieved. The median [IQR] prednisone dose was also reduced from 20 [11.3-47.5] mg/day at ANK onset to 5 [0-10] at 12 months. After a median [IQR] follow-up of 16 [5-50] months, the most important side effects were cutaneous manifestations (n = 8), mild leukopenia (n = 3), myopathy (n = 1), and infections (n = 5). ANK is associated with rapid and maintained clinical and laboratory improvement, even in nonresponders to other biologic agents. However, joint manifestations are more refractory than the systemic manifestations.

  10. Congenital and prolonged adult-onset deafness cause distinct degradations in neural ITD coding with bilateral cochlear implants.

    Bilateral cochlear implant (CI) users perform poorly on tasks involving interaural time differences (ITD), which are critical for sound localization and speech reception in noise by normal-hearing listeners. ITD perception with bilateral CI is influenced by age at onset of deafness and duration of deafness. We previously showed that ITD coding in the auditory midbrain is degraded in congenitally deaf white cats (DWC) compared to acutely deafened cats (ADC) with normal auditory development (Hancock et al., J. Neurosci, 30:14068). To determine the relative importance of early onset of deafness and prolonged duration of deafness for abnormal ITD coding in DWC, we recorded from single units in the inferior colliculus of cats deafened as adults 6 months prior to experimentation (long-term deafened cats, LTDC) and compared neural ITD coding between the three deafness models. The incidence of ITD-sensitive neurons was similar in both groups with normal auditory development (LTDC and ADC), but significantly diminished in DWC. In contrast, both groups that experienced prolonged deafness (LTDC and DWC) had broad distributions of best ITDs around the midline, unlike the more focused distributions biased toward contralateral-leading ITDs present in both ADC and normal-hearing animals. The lack of contralateral bias in LTDC and DWC results in reduced sensitivity to changes in ITD within the natural range. The finding that early onset of deafness more severely degrades neural ITD coding than prolonged duration of deafness argues for the importance of fitting deaf children with sound processors that provide reliable ITD cues at an early age.

    Maternal or social deprivation during early infancy inevitably produces social deficiencies in juvenile chimpanzees. Hypothesizing such deficiencies to persist into adulthood (a), and, as in humans, a sensitive period in early infancy for attachment formation (b), we predicted and found behavioral differences in resocialized adult ex-laboratory chimpanzees after about 20 years of solitary confinement depending on their age at onset of deprivation: early deprived (ED; mean: 1.2 years) chimpanzees engaged significantly less in social interactions, spent less time associated, and showed more nonsocial idiosyncrasies than did late deprived (LD; mean: 3.6 years) chimpanzees. In addition to these individual attributes relational qualities, specifically the combination of ED and LD chimpanzees within social groups, have an impact on social recovery. LDs can best exploit their social potential in the company of other LDs and EDs tend to stagnate in their recovery when socialized with other EDs.

    A 45-year-old hypertensive Japanese woman presented with epigastric pain on inspiration, fever, complete atrioventricular block and polyarthritis. Her antistreptolysin O levels were markedly elevated. A diagnosis of rheumatic fever was made according to the modified Jones criteria. She was prescribed loxoprofen sodium, which was partially effective for her extracardiac clinical symptoms. However, she had syncope due to complete atrioventricular block with asystole longer than 10 seconds. Consequently, we implanted a permanent pacemaker. Although we prescribed prednisolone, the efficacy of which was limited for the patient's conduction disturbance, the complete atrioventricular block persisted. In our systematic review of 12 similar cases, the duration of complete heart block was always transient and there was no case requiring a permanent pacemaker. We thus encountered a very rare case of adult-onset acute rheumatic fever with persistent complete atrioventricular block necessitating permanent pacemaker implantation.

    Pulmonary involvement in the form of acute pneumonitis in adult-onset Still's disease (AOSD) is an uncommon manifestation, with few cases reported in the literature. We report the case of a 61-year-old male with 3 years of AOSD evolution, treated with methotrexate (MTX) and half-dose corticosteroids, which debuted with symptoms of fever, dyspnea and dry cough after 3 weeks of receiving the first dose of tocilizumab (TCZ). In the follow-up study showed leukocytosis with left shift, elevated serum ferritin and C-reactive protein standard. The chest CT scan showed ground-glass pattern predominantly in central and upper lobes and the BAL shows an increase in the percentage of lymphocyte with normal subpopulations and negative cultures. MTX and TCM were suspended, prednisone was increased to 30mg/day and within a week Anakinra 100mg/day SC was iniciated, noting in a few days a progressive clinical, analytical and radiological improvement.

  14. Outdoor air pollution and asthma

    Traffic and power generation are the main sources of urban air pollution. The idea that outdoor air pollution can cause exacerbations of pre-existing asthma is supported by an evidence base that has been accumulating for several decades, with several studies suggesting a contribution to new-onset asthma as well. In this Series paper, we discuss the effects of particulate matter (PM), gaseous pollutants (ozone, nitrogen dioxide, and sulphur dioxide), and mixed traffic-related air pollution. We focus on clinical studies, both epidemiological and experimental, published in the previous 5 years. From a mechanistic perspective, air pollutants probably cause oxidative injury to the airways, leading to inflammation, remodelling, and increased risk of sensitisation. Although several pollutants have been linked to new-onset asthma, the strength of the evidence is variable. We also discuss clinical implications, policy issues, and research gaps relevant to air pollution and asthma. PMID:24792855

    The Hyperornithinemia-Hyperammonemia-Homocitrullinuria (HHH) syndrome is a disorder of the urea cycle and ornithine degradation pathway caused by mutations in the mitochondrial ornithine transporter, ORNT1 (SLC25A15). In general, the majority of patients with HHH syndrome come to medical attention during infancy or early school years with symptoms such as learning disabilities, changes in cognitive development, spasticity, or liver dysfunction. In this report, we describe a 35-year-old male of Indian descent who was diagnosed with HHH syndrome after he presented to the emergency room with gastroenteritis, disorientation, and slurred speech. Molecular analysis revealed that this patient was heterozygous for two ORNT1 mutations, p.[Gly220Arg(+)Arg275X] (c.[658G>A(+)823C>T]) that had been previously reported in homozygous probands who presented during the first year of life. Cellular studies revealed that the ORNT1 p.Gly220Arg mutation was nonfunctional but targeted to the mitochondria. Given that this patient was a successful college graduate on a vegetarian diet without a prior history of learning or neurological impairment, additional factors such as gene redundancy, environmental, and epigenetic factors may have contributed to the delay in onset of presentation and lack of any previous symptoms. To the best of our knowledge, this is the first reported case of an adult-onset HHH syndrome presentation without a prior history of neurological or cognitive deficiency.

    Objective: To investigate mental health problems in adults with pediatric-onset spinal cord injury (SCI) and explore how these problems relate to the risk of negative outcomes over time. Method: The study included 466 adults who sustained an SCI prior to age 19 years and had been injured for at least 1 year. Participants were interviewed on an approximately annual basis using a study-specific questionnaire and standardized measures of depression, anxiety, substance use, and community involvement. Generalized estimating equations were used to assess the risk of negative outcomes across time as a function of depression, anxiety, and substance misuse. Results: Of the participants who reported on each domain of mental health, 26% reported misuse of alcohol or drugs (122/466), 21% reported problems with depression (78/360), and 29% reported problems with anxiety (49/168). Depression was associated with increased odds of pressure ulcers, urinary tract infections, hospitalizations, pain, and smoking and lower levels of economic independence and mobility. Anxiety was associated with increased odds of hospitalization, pain, and smoking. Substance misuse predicted an increased risk of pressure ulcers, pain, and smoking and decreased odds of occupational involvement. When examining the effect of mental health with time, results showed that depression accelerated the risk of urinary tract infections, respiratory complications, and hospitalizations and anxiety and depression accelerated risk for lower occupational independence. Conclusions: The added burden that mental health difficulties pose for medical and psychosocial outcomes highlight the importance of monitoring and treating mental health symptoms in pediatric-onset SCI.

    Although low-back pain and depression are common comorbidities, the mechanisms responsible for their association remain unclear. The effects of proinflammatory cytokines on the hypothalamic-pituitary-adrenal (HPA) axis lead to the hypothesis that allergic reactions, as markers for inflammation-associated activation of the HPA axis, result in aberrant responses to subsequent stressors. Data from 6,836 US adults 20-39 years old from the Third National Health and Nutrition Examination Survey (1988-1994) were used. Subjects responded to questions regarding low-back pain in the past 12 months and history of asthma, hay fever, and other allergies. The history and onset of major depression were obtained from the Diagnostic Interview Schedule. Logistic regression modeling was used to estimate the associations between allergies and depression and low-back pain. Subjects with a history of any allergy were more likely to report low-back pain (odds ratio = 1.51; 95% confidence interval: 1.16, 1.96), to be diagnosed with major depression (odds ratio = 1.58; 95% confidence interval: 1.13, 2.21), and much more likely to have both major depression and low-back pain (odds ratio = 3.03; 95% confidence interval: 1.32, 6.92). Hypersensitivity reactions may prime the HPA axis to respond aberrantly to stressors, resulting in physical and behavioral consequences.

    The transition of adult patients with childhood-onset chronic diseases (APCCD) from pediatric to adult health-care systems has recently received worldwide attention. However, Japan is lagging behind European countries and North America as this concept of health-care transition was introduced only 10 years ago. In Japan, before the introduction of this concept, APCCD were referred to as "carryover patients," who were often considered a burden in pediatric practice. In the late 1990s, groups composed of pediatric nephrologists, developmental and behavioral pediatricians, pediatric nurses, and special education teachers researching the quality of life of adult patients with chronic kidney disease began to discuss the physical and psychosocial problems of APCCD. In 2006, a group of pediatricians first introduced the term "transition" in a Japanese journal. By 2010, a group of adolescent nurses had begun a specialized training program aimed at supporting patients during the transitional period. In 2013, the Ministry of Health, Labour and Welfare in Japan convened a research committee, focusing on issues related to social, educational, and medical support for APCCD, and the Japan Pediatric Society established a committee for the health-care transition of APCCD and summarized their statements. Moreover, in 2013, the Tokyo Metropolitan Children's Medical Center initiated ambulatory services for APCCD managed by specialized nurses. The concept of health-care transition has rapidly spread over these past 10 years. The purpose of this article is to describe how this concept of health-care transition has advanced in Japan, such that APCCD now experience a positive pediatric to adult health-care transition.

    The long-term efficacy and safety of sodium valproate and carbamazepine in adult outpatients with newly diagnosed primary generalised or partial and secondarily generalised seizures were compared in a randomised, open, multicentre study at 22 neurology outpatient clinics. Patients were randomised to oral sodium valproate (Epilim EC enteric coated 200 mg tablets twice daily, n = 149) or oral carbamazepine (100 mg twice daily increasing to 200 mg twice daily in week 2, n = 151) and followed up for three years. If clinically necessary, dosages were regularly increased until seizures were controlled or toxicity developed. Sodium valproate and carbamazepine controlled both primary generalised and partial seizures equally effectively overall. Significantly more patients on sodium valproate than carbamazepine (126/140 (90%) v 105/141 (75%), p = 0.001) remained on randomised treatment for at least six months. Skin rashes occurred significantly more often in carbamazepine recipients than in sodium valproate recipients (11.2% v 1.7%, p < 0.05) and carbamazepine was associated with a higher withdrawal rate because of adverse events (15% v 5% on sodium valproate) in the first six months of treatment. There was no difference between the drugs in the rate of withdrawal because of poor seizure control at any stage, regardless of seizure type. At the end of the three year trial period, over 70% of the available patients were still on randomised treatment or had recently stopped treatment after achieving full seizure control. Sodium valproate and carbamazepine were both associated with a high degree of overall seizure control regardless of seizure type and both have good long-term tolerability in adult patients with newly diagnosed epilepsy. Recommendations are made for a higher initial dosage regime for sodium valproate in partial seizures. PMID:8006647

    The observation that cancer often arises at sites of chronic inflammation has prompted the idea that carcinogenesis and inflammation are deeply interwoven. In fact, the current literature highlights a role for chronic inflammation in virtually all the steps of carcinogenesis, including tumor initiation, promotion and progression. The aim of the present article is to review the current literature on the involvement of chronic inflammation in the initiation step and in the very early phases of tumorigenesis, in a type of cancer where adult stem cells are assumed to be the cells of origin of neoplasia. Since the gastrointestinal tract is regarded as the best-established model system to address the liaison between chronic inflammation and neoplasia, the focus of this article will be on intestinal cancer. In fact, the anatomy of the intestinal epithelial lining is uniquely suited to study adult stem cells in their niche, and the bowel crypt is an ideal developmental biology system, as proliferation, differentiation and cell migration are all distributed linearly along the long axis of the crypt. Moreover, crypt stem cells are regarded today as the most likely targets of neoplastic transformation in bowel cancer. More specifically, the present review addresses the molecular mechanisms whereby a state of chronic inflammation could trigger the neoplastic process in the intestine, focusing on the generation of inflammatory cues evoking enhanced proliferation in cells not initiated but at risk of neoplastic transformation because of their stemness. Novel experimental approaches, based on triggering an inflammatory stimulus in the neighbourhood of adult intestinal stem cells, are warranted to address some as yet unanswered questions. A possible approach, the targeted transgenesis of Paneth cells, may be aimed at ‘hijacking’ the crypt stem cell niche from a status characterized by the maintenance of homeostasis to local chronic inflammation, with the prospect of initiating

    Background Children diagnosed with some forms of strabismus were recently found to have an increased risk of developing mental illness by early adulthood. The purpose of this case-controlled study was to determine if adults with non-paralytic forms of strabismus are similarly at an elevated risk for developing mental illness. Methods The medical records of all patients diagnosed as adults (≥ 19 years of age) with convergence insufficiency (CI, n=118), divergence insufficiency (DI, n=80), and small angle hypertropia (HT, n=99) from January 1, 1985, through December 31, 2004, were retrospectively reviewed. Each case was compared with a sex- and birthdate-matched non-strabismic control. The medical records were reviewed for mental health diagnoses, including inpatient and outpatient encounters, psychiatric ER visits, and medication use. Results Mental health disorders were diagnosed in 65 (55.1%) patients with CI compared to 54 (45.8%) controls (p=0.15), in 51 (63.8%) patients with DI compared to 42 (52.5%) controls (p=0.15), and in 63 (63.6%) patients with HT compared to 57 (57.6%) controls (p=0.38). CI patients were not more likely to have mental health disorders than their controls (p=0.15). Mental health hospitalizations (p=0.02), psychiatric medication use (p=0.04), and unspecified anxiety disorders (p=0.03) were higher in DI patients compared to controls. HT patients were found to have more generalized anxiety disorders (p=0.003) than controls. Conclusions Adults with some forms of strabismus (DI and HT) appear to have an increased risk of mental illness and its comorbidities, compared to age- and gender-matched non-strabismic controls.

    Henoch-Schonlein Purpura (HSP) is a small vessel vasculitis mediated by IgA-immune complex deposition. It is characterized by the clinical tetrad of non-thrombocytopenic palpable purpura, abdominal pain, arthritis and renal involvement. Pathologically, it can be considered a form of immune complex-mediated leukocytoclastic vasculitis (LCV) involving the skin and other organs. Though it primarily affects children (over 90% of cases), the occurrence in adults has been rarely reported. Management often involves the use of immunomodulatory or immune-suppressive regimens.

    2016-01-01

    Increased awareness of asthma in society and altered diagnostic practices makes evaluation of data on prevalence change difficult. In most parts of the world the asthma prevalence seems to still be increasing. The increase is associated with urbanization and has been documented particularly among children and teenagers in urban areas of middle- and low-level income countries. Use of validated questionnaires has enabled comparisons of studies. Among adults there are few studies based on representative samples of the general population which allow evaluation of time trends of prevalence. This review focuses mainly on studies of asthma prevalence and symptoms among adults. Parallel with increased urbanization, we can assume that the increase in asthma prevalence in most areas of the world will continue. However, in Australia and North-West Europe studies performed, particularly among children and adolescents, indicate that the increase in asthma prevalence may now be leveling off.

    The clinical expression of systemic lupus erythematosus (SLE) is influenced by genetic and environmental factors and therefore varies between ethnicities. Information on the epidemiology of SLE in Brazil is scarce and practically limited to studies conducted in socioeconomically developed regions (South and Southeast). The objective of this study was to describe the clinical and immunological aspects and outcome of a cohort of patients with SLE treated at a university hospital in northeastern Brazil and compare patterns related to age at onset: childhood (cSLE), adult (aSLE), and late (lSLE). A random sample of 414 records (women: 93.5%) were reviewed. The mean age at SLE onset and the mean disease duration were 28.9 ± 10.9 years and 10.2 ± 6.6 years, respectively. Most patients had aSLE (n = 338; 81.6%), followed by cSLE (n = 60; 14.5%) and lSLE (n = 16; 3.9%). The female/male ratio was 6.5:1 in cSLE and 16.8:1 in aSLE; in lSLE, all patients were female (p = 0.05). During follow-up, the cSLE group presented higher rates of nephritis (70% vs. 52.9% vs. 12.5%; p = 0.0001) and leuko/lymphopenia (61.7% vs. 43.8% vs. 56.2%; p = 0.02). No significant differences were found for anti-dsDNA, anti-Sm, and antiphospholipid antibodies. Treatment with immunosuppressants was significantly more common, and higher doses of prednisone were used, in cSLE. The prevalence of cardiovascular diseases were more frequent in lSLE (p = 0.03). No significant differences were found between the three groups with regard to mean damage accrual (SDI), remission, and mortality. Although cSLE presented higher rates of nephritis and leuko/lymphopenia, more frequent use of immunosuppressants and higher prednisone doses than aSLE and lSLE, the three groups did not differ significantly with regard to damage accrual, remission, and mortality.

    The objective of this study was to characterize and compare muscle histopathological findings in 3 different genetic motor neuron disorders. We retrospectively re-assessed muscle biopsy findings in 23 patients with autosomal dominant lower motor neuron disease caused by p.G66V mutation in CHCHD10 (SMAJ), 10 X-linked spinal and bulbar muscular atrophy (SBMA) and 11 autosomal dominant c9orf72-mutated amyotrophic lateral sclerosis (c9ALS) patients. Distinct large fiber type grouping consisting of non-atrophic type IIA muscle fibers were 100% specific for the late-onset spinal muscular atrophies (SMAJ and SBMA) and were never observed in c9ALS. Common, but less specific findings included small groups of highly atrophic rounded type IIA fibers in SMAJ/SBMA, whereas in c9ALS, small group atrophies consisting of small-caliber angular fibers involving both fiber types were more characteristic. We also show that in the 2 slowly progressive motor neuron disorders (SMAJ and SBMA) the initial neurogenic features are often confused with considerable secondary "myopathic" changes at later disease stages, such as rimmed vacuoles, myofibrillar aggregates and numerous fibers reactive for fetal myosin heavy chain (dMyHC) antibodies. Based on our findings, muscle biopsy may be valuable in the diagnostic work-up of suspected motor neuron disorders in order to avoid a false ALS diagnosis in patients without clear findings of upper motor neuron lesions.

    Eighteen patients, twenty-five to fifty-two years old, who had juvenile-onset diabetes, had neuropathic arthropathy and fractures at the ankle or tarsus, most of which were bilateral. After a minimum follow-up of one year, four patients could not walk and fourteen were dependent on orthoses. In nine patients, the lesions produced fixed skeletal deformities that caused severe malum perforans, which in three patients was so severe that a below-the-knee amputation had to be done. In patients who had bilateral lesions, when the extremity that was initially involved was prevented from bearing weight, involvement of the contralateral limb became evident after an average of 4.5 months, compared with an average of twelve months in the patients who were allowed weight-bearing on the extremity that was initially involved. Our current treatment protocol is non-weight-bearing immobilization of the involved extremity, and we recommend prophylactic immobilization of the contralateral extremity with a protective cast or orthosis. All of the patients who had this treatment regimen could walk; in contrast, of the eleven patients who were not so treated, four could not walk.

    The objective of this study was to characterize and compare muscle histopathological findings in 3 different genetic motor neuron disorders. We retrospectively re-assessed muscle biopsy findings in 23 patients with autosomal dominant lower motor neuron disease caused by p.G66V mutation in CHCHD10 (SMAJ), 10 X-linked spinal and bulbar muscular atrophy (SBMA) and 11 autosomal dominant c9orf72-mutated amyotrophic lateral sclerosis (c9ALS) patients. Distinct large fiber type grouping consisting of non-atrophic type IIA muscle fibers were 100% specific for the late-onset spinal muscular atrophies (SMAJ and SBMA) and were never observed in c9ALS. Common, but less specific findings included small groups of highly atrophic rounded type IIA fibers in SMAJ/SBMA, whereas in c9ALS, small group atrophies consisting of small-caliber angular fibers involving both fiber types were more characteristic. We also show that in the 2 slowly progressive motor neuron disorders (SMAJ and SBMA) the initial neurogenic features are often confused with considerable secondary “myopathic” changes at later disease stages, such as rimmed vacuoles, myofibrillar aggregates and numerous fibers reactive for fetal myosin heavy chain (dMyHC) antibodies. Based on our findings, muscle biopsy may be valuable in the diagnostic work-up of suspected motor neuron disorders in order to avoid a false ALS diagnosis in patients without clear findings of upper motor neuron lesions.

    Cartilage hair hypoplasia (CHH) is an autosomal recessive disorder caused by mutations in the ribonuclease mitochondrial RNA-processing (RMRP) gene. Although its most constant feature is metaphyseal dysplasia with short stature, CHH is associated with extraskeletal defects such as thin hair, anemia, immunodeficiency, and increased incidence of lymphomas. The spectrum of immunologic phenotypes in CHH translates into clinical severity. Whereas T-cell deficiency may remain subclinical or may result in severe combined immunodeficiency or Omenn syndrome, humoral immunodeficiency has only rarely been noted in these patients. Here we report the diagnosis of CHH in a woman who presented with severe short stature and a full-blown antibody deficiency, clinically resembling common variable immunodeficiency. Sequencing of the RMRP gene revealed compound heterozygosity for two novel mutations (g.68_69delinsTT and g.76C>T). Despite the late onset of immunodeficiency in the patient, its clinical course was severe, and the patient died 3 years after the first diagnosis.

    Epidural emphysema is an exceptional complication of bronchial asthma, revealed by an incidental finding in chest tomography. We report a case of a 21-year-old man admitted with asthma attack complicated by subcutaneous and mediastinal emphysema. Chest tomography confirmed the mediastinal emphysema and also revealed the epidural emphysema within the vertebral canal. Neurological examination was negative. The patient showed complete recovery 10days after the onset of symptoms. The epidural emphysema is a rare complication during asthma attacks. The benignity of this complication should not require a systematic chest tomography.

    Exercise-induced bronchospasm (EIB) commonly affects patients with asthma. However, the relationship between EIB and asthma control remains unclear. Exercise limitation due to asthma might lead to reduced physical activity, but little information is available regarding obesity and EIB in asthma. A recent survey evaluated the frequency of EIB and exercise-related respiratory symptoms in a large number of patients with asthma. The survey results were reanalyzed to address any relationship between EIB and asthma control and obesity. A nationwide random sample of children aged 4-12 years (n = 250), adolescents aged 13-17 years (n = 266), and adults aged ≥18 years (n = 1001) with asthma were interviewed by telephone. Questions in the survey addressed asthma symptoms in general, medication use, and height and weight. Asthma control was categorized using established methods in the Expert Panel Report 3. Body mass index (BMI) was calculated using standard nomograms and obesity was defined as a BMI ≥ 30 kg/m(2). Most children (77.6%), adolescents (71.1%), and adults (83.1%) had either "not well" or "very poorly" controlled asthma. Children with "not well" controlled asthma reported a history of EIB significantly more often than those with "well" controlled" asthma. Asthma patients of all ages who had "not well" and "very poorly" controlled asthma described multiple (four or more) exercise-related respiratory symptoms significantly more often than those with "well-controlled" asthma. Obesity was significantly more common in adolescents with "not well" and "very poorly" controlled asthma and adults with "very poorly" controlled asthma. Children, adolescents, and adults with asthma infrequently have well-controlled disease. A history of EIB and exercise-related respiratory symptoms occur more commonly in patients with not well and very poorly controlled asthma. Obesity was found more often in adolescents and adults, but not children, with asthma, which was not well and

    Niemann-Pick type C disease (NPC) is a recessive neurolipidosis. We report five adolescent and adult NPC cases to underscore the frequency and heterogeneity of movement disorders in NPC. Clinical, morphologic, biochemical and genetic study was performed in the five patients. Disease onset was between 8 and 50 years. Movement disorders were present in all cases, were heterogeneous and often combined [cerebellar ataxia (5/5), myoclonus (3/5), dystonia (2/5), chorea (1/5) and tremor (1/5)] and were the first sign in 4/5. Two patients were reported to have no vertical supranuclear gaze palsy (VSGP) at the first examination. Two patients experienced acute neuropsychiatric signs leading to death in one case due to myoclonic storm. Filipin staining was always positive. Two NPC1 mutations were identified in three patients, only one in two siblings. NPC should be considered in case of unexplained movement disorders, even when VSGP or cataplexy are not reported. Filipin staining remains a strong support for the diagnosis. Treatment with miglustat should be considered which is currently the only approved disease-specific treatment of NPC in children and adults.

    In previous studies, patients with dysthymic disorder (DD) have reported significantly more adverse early home environments than patients with episodic major depressive disorder (MDD) and normal controls. However, DD is also associated with increased rates of mood and personality disorders in first-degree relatives, raising the possibility that the DD-early adversity relationship may be due to the confounding effects of parental psychopathology. The present study addressed this issue using a sample of 97 adult outpatients with early-onset DD, 45 adult outpatients with episodic MDD, and 45 normal controls, and their first-degree relatives. The early home environment was assessed with semi-structured interviews and self-report inventories. Parental psychopathology was assessed using semi-structured direct and family history interviews, and diagnoses were assigned using the best-estimate procedure. Results indicated that parental mood and personality disorders were strongly associated with probands' reports of early adversity. However, patients with DD continued to differ significantly from patients with episodic MDD and normal controls after controlling for parental psychopathology.

    Amyotrophic lateral sclerosis (ALS) is a devastating paralytic disorder caused by dysfunction and degeneration of motor neurons starting in adulthood. Most of our knowledge about the pathophysiological mechanisms of ALS comes from transgenic mice models that emulate a subgroup of familial ALS cases (FALS), with mutations in the gene encoding superoxide dismutase (SOD1). In the more than 15 years since these mice were generated, a large number of abnormal cellular mechanisms underlying motor neuron degeneration have been identified, but to date this effort has led to few improvements in therapy, and no cure. Here, we consider that this surfeit of mechanisms is best interpreted by current insights that suggest a very early initiation of pathology in motor neurons, followed by a diversity of secondary cascades and compensatory mechanisms that mask symptoms for decades, until trauma and/or aging overloads their protective function. This view thus posits that adultonset ALS is the consequence of processes initiated during early development. In fact, motor neurons in neonatal mutant SOD mice display important alterations in their intrinsic electrical properties, synaptic inputs and morphology that are accompanied by subtle behavioral abnormalities. We consider evidence that human mutant SOD1 protein in neonatal hSOD1G93A mice instigates motor neuron degeneration by increasing persistent sodium currents and excitability, in turn altering synaptic circuits that control excessive motor neuron firing and leads to excitotoxicity. We also discuss how therapies that are aimed at suppressing abnormal neuronal activity might effectively mitigate or prevent the onset of irreversible neuronal damage in adulthood. PMID:22740507

    Chronic progressive external ophthalmoplegia (CPEO) is common in mitochondrial disorders and is frequently associated with multiple mtDNA deletions. The onset is typically in adulthood, and affected subjects can also present with general muscle weakness. The underlying genetic defects comprise autosomal-dominant or recessive mutations in several nuclear genes, most of which play a role in mtDNA replication. Next-generation sequencing led to the identification of compound-heterozygous RNASEH1 mutations in two singleton subjects and a homozygous mutation in four siblings. RNASEH1, encoding ribonuclease H1 (RNase H1), is an endonuclease that is present in both the nucleus and mitochondria and digests the RNA component of RNA-DNA hybrids. Unlike mitochondria, the nucleus harbors a second ribonuclease (RNase H2). All affected individuals first presented with CPEO and exercise intolerance in their twenties, and these were followed by muscle weakness, dysphagia, and spino-cerebellar signs with impaired gait coordination, dysmetria, and dysarthria. Ragged-red and cytochrome c oxidase (COX)-negative fibers, together with impaired activity of various mitochondrial respiratory chain complexes, were observed in muscle biopsies of affected subjects. Western blot analysis showed the virtual absence of RNase H1 in total lysate from mutant fibroblasts. By an in vitro assay, we demonstrated that altered RNase H1 has a reduced capability to remove the RNA from RNA-DNA hybrids, confirming their pathogenic role. Given that an increasing amount of evidence indicates the presence of RNA primers during mtDNA replication, this result might also explain the accumulation of mtDNA deletions and underscores the importance of RNase H1 for mtDNA maintenance.

    Light detection and ranging (LIDAR) can estimate daily volumes of sand dust particles from the East Asian desert to Japan. The objective of this study was to investigate the relationship between sand dust particles and pulmonary function, and respiratory symptoms in adult patients with asthma. One hundred thirty-seven patients were included in the study. From March 2013 to May 2013, the patients measured their morning peak expiratory flow (PEF) and kept daily lower respiratory symptom diaries. A linear mixed model was used to estimate the correlation of the median daily levels of sand dust particles, symptoms scores, and PEF. A heavy sand dust day was defined as an hourly concentration of sand dust particles of >0.1 km(-1). By this criterion, there were 8 heavy sand dust days during the study period. Elevated sand dust particles levels were significantly associated with the symptom score (0.04; 95% confidence interval (CI); 0.03, 0.05), and this increase persisted for 5 days. There was no significant association between PEF and heavy dust exposure (0.01 L/min; 95% CI, -0.62, 0.11). The present study found that sand dust particles were significantly associated with worsened lower respiratory tract symptoms in adult patients with asthma, but not with pulmonary function.

    Emerging evidence suggests sex differences in the early origins of adult metabolic disease, but this has been little investigated in developing countries. We investigated sex-specific associations between low birth weight (LBW; <2.5 kg) and adult-onset diabetes in 12,525 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Diabetes was defined by self-reported information and laboratory measurements. In confounder-adjusted analyses, LBW (vs. 2.5–4 kg) was associated with higher prevalence of diabetes in women (Prevalence Ratio (PR) 1.54, 95% CI: 1.32–1.79), not in men (PR 1.06, 95% CI: 0.91–1.25; Pheterogeneity = 0.003). The association was stronger among participants with maternal diabetes (PR 1.60, 95% CI: 1.35–1.91), than those without (PR 1.15, 95% CI: 0.99–1.32; Pheterogeneity = 0.03). When jointly stratified by sex and maternal diabetes, the association was observed for women with (PR 1.77, 95% CI: 1.37–2.29) and without (PR 1.45, 95% CI: 1.20–1.75) maternal diabetes. In contrast, in men, LBW was associated with diabetes in participants with maternal diabetes (PR 1.45, 95% CI: 1.15–1.83), but not in those without (PR 0.92, 95% CI: 0.74–1.14). These sex-specific findings extended to continuous measures of glucose homeostasis. LBW was associated with higher diabetes prevalence in Brazilian women, and in men with maternal diabetes, suggesting sex-specific intrauterine effects on adult metabolic health. PMID:27845438

    Aβ peptide accumulation is thought to be the primary event in the pathogenesis of Alzheimer's disease (AD), with downstream neurotoxic effects including the hyperphosphorylation of tau protein. Glycogen synthase kinase-3 (GSK-3) is increasingly implicated as playing a pivotal role in this amyloid cascade. We have developed an adult-onset Drosophila model of AD, using an inducible gene expression system to express Arctic mutant Aβ42 specifically in adult neurons, to avoid developmental effects. Aβ42 accumulated with age in these flies and they displayed increased mortality together with progressive neuronal dysfunction, but in the apparent absence of neuronal loss. This fly model can thus be used to examine the role of events during adulthood and early AD aetiology. Expression of Aβ42 in adult neurons increased GSK-3 activity, and inhibition of GSK-3 (either genetically or pharmacologically by lithium treatment) rescued Aβ42 toxicity. Aβ42 pathogenesis was also reduced by removal of endogenous fly tau; but, within the limits of detection of available methods, tau phosphorylation did not appear to be altered in flies expressing Aβ42. The GSK-3–mediated effects on Aβ42 toxicity appear to be at least in part mediated by tau-independent mechanisms, because the protective effect of lithium alone was greater than that of the removal of tau alone. Finally, Aβ42 levels were reduced upon GSK-3 inhibition, pointing to a direct role of GSK-3 in the regulation of Aβ42 peptide level, in the absence of APP processing. Our study points to the need both to identify the mechanisms by which GSK-3 modulates Aβ42 levels in the fly and to determine if similar mechanisms are present in mammals, and it supports the potential therapeutic use of GSK-3 inhibitors in AD.

    Asthma is a prevalent and serious health problem in Korea. Recently, the Korean Asthma Guideline has been updated by The Korean Academy of Tuberculosis and Respiratory Diseases (KATRD) in an effort to improve the clinical management of asthma. This guideline focuses on adult patients with asthma and aims to deliver up to date scientific evidence and recommendations to general physicians for the management of asthma. For this purpose, this guideline was updated following systematic review and meta-analysis of recent studies and adapting some points of international guidelines (Global Initiative for Asthma [GINA] report 2014, National Asthma Education and Prevention Program [NAEPP] 2007, British Thoracic Society [BTS/SIGN] asthma guideline 2012, and Canadian asthma guideline 2012). Updated issues include recommendations derived using the population, intervention, comparison, and outcomes (PICO) model, which produced 20 clinical questions on the management of asthma. It also covers a new definition of asthma, the importance of confirming various airflow limitations with spirometry, the epidemiology and the diagnostic flow of asthma in Korea, the importance and evidence for inhaled corticosteroids (ICS) and ICS/formoterol as a single maintenance and acute therapy in the stepwise management of asthma, assessment of severity of asthma and management of exacerbation, and an action plan to cope with exacerbation. This guideline includes clinical assessments, and treatment of asthma–chronic obstructive pulmonary disease overlap syndrome, management of asthma in specific conditions including severe asthma, elderly asthma, cough variant asthma, exercise-induced bronchial contraction, etc. The revised Korean Asthma Guideline is expected to be a useful resource in the management of asthma.

    Asthma is a major public health concern, with an estimated 18.8 million adults in the United States having the disease. Asthma can be controlled with a variety of effective treatment options; however, only half the people with asthma report their asthma is well controlled. Uncontrolled asthma leads to high direct and indirect costs as well as decreased quality of life. The pathophysiology of asthma, current asthma practice guidelines, and common barriers to self-management will be discussed. Through use of motivational interviewing techniques and knowledge of available self-management tools, the home care clinician is poised to help increase self-management of asthma, decrease hospitalizations, and improve quality of life.

    The role of seasons should be taken into account in the management of asthma. The environment varies between seasons and it is well documented that asthma is modulated by environment. Viruses cause asthma exacerbations peak, in winter, in adults while the peak is present in September in children. Allergens are probably a less powerful source of asthma exacerbation than viruses but pollen involvement in spring and summer and dust mites in autumn are indisputable. Air pollutants, present in summer during the hottest periods, are also highly involved in asthma exacerbations. Indoor air pollution, in winter, is also implicated in asthma disease. All these environmental factors are synergistic and increase the risk of asthma exacerbation. Therapies should be adapted to each season depending on environmental factors potentially involved in the asthma disease.

    Chronic obstructive pulmonary disease (COPD) and asthma are common airway disorders characterized by chronic airway inflammation and airflow obstruction, and are a leading cause of morbidity and mortality in the People’s Republic of China. These two diseases pose a high economic burden on the family and the whole of society. Despite evidence-based Global Initiative for Chronic Obstructive Lung Disease and Global Initiative for Asthma guidelines being available for the diagnosis and management of COPD and asthma, many of these patients are not properly diagnosed or managed in the People’s Republic of China. The value of combination therapy with inhaled corticosteroids and long-acting β2-agonists has been established in the management of asthma and COPD globally. Combinations of inhaled corticosteroids and long-acting β2-agonists such as fluticasone and salmeterol, have been shown to be effective for improving symptoms, health status, and reducing exacerbations in both diseases. In this review, we discuss the efficacy and safety of this combination therapy from key studies, particularly in the People’s Republic of China. PMID:25926729

    The epigenome provides a substrate through which environmental exposures can exert their effects on gene expression and disease risk, but the relative importance of epigenetic variation on human disease onset and progression is poorly characterized. Asthma is a heterogeneous disease of the airways, for which both onset and clinical course result from interactions between host genotype and environmental exposures, yet little is known about the molecular mechanisms for these interactions. We assessed genome-wide DNA methylation using the Infinium Human Methylation 450K Bead Chip and characterized the transcriptome by RNA sequencing in primary airway epithelial cells from 74 asthmatic and 41 nonasthmatic adults. Asthma status was based on doctor’s diagnosis and current medication use. Genotyping was performed using various Illumina platforms. Our study revealed a regulatory locus on chromosome 17q12-21 associated with asthma risk and epigenetic signatures of specific asthma endotypes and molecular networks. Overall, these data support a central role for DNA methylation in lung cells, which promotes distinct molecular pathways of asthma pathogenesis and modulates the effects of genetic variation on disease risk and clinical heterogeneity.

  6. Occupational asthma often goes unrecognised.

    Occupational asthma is induced de novo by an airborne agent encountered in the workplace. The risk of occupational asthma is greater in those with a prior atopic history. Work-exacerbated asthma is the provocation of pre-existing, or coincidental, disease by one or more irritant exposures at work. Distinguishing occupational from work-exacerbated asthma can be difficult but it is important since the two have very different clinical, occupational and legal implications. Occupational asthma is underrecognised, the disease often develops in young people who are otherwise fit. They may not recognise their symptoms as anything out of the ordinary, or may confuse them with hay fever or a cold. It is sensible to consider occupational and work-exacerbated asthma in every working adult who has asthma or who presents with suggestive symptoms such as rhinitis. Occupational asthma almost always arises from an immediate-type hypersensitivity reaction to a respiratory sensitising agent in the workplace. The disease has a short latency with symptoms developing 6 to 36 months after employment in a new job. Rhinitis is common and in those working in an environment with airborne proteins the absence of rhinitis effectively rules out occupational asthma. In occupational asthma, symptoms (including nasal symptoms) improve away from work. Once the disease is established symptoms are provoked by even very small exposures at work and begin to be provoked by a wide variety of irritant exposures both at, and away from, work. It is good practice to enquire into the employment of every working-age adult with asthma, or rhinitis, and particularly in those presenting with new symptoms or symptoms that have become more difficult to manage. Patients should routinely be asked whether their symptoms improve when they are not at work.

    Diabetes mellitus (DM) is a metabolic disorder caused by hyperglycemia which leads to dysfunction of various organs. Hearing acuity is equally hindered by this disorder. Among individuals with DM audiological characteristics of DM type 1 are of great concern in the literature. This study aims at establishing high frequency audiometry (HFA) as a useful tool in identifying early onset of hearing loss in individuals with DM type 2. 20 non-diabetic participants and 20 individuals with DM type 2 in the age range of 20-40 years were considered for the study. Subjects in both groups underwent otoscopic examination, PTA at 0.25, 0.5, 1, 2, 4 and 8 kHz and HFA at 9, 10, 11.2, 12.5, 14 and 16 kHz. Results revealed statistically significant difference in thresholds of both PTA and HFA at all frequencies across the group, but the mean threshold difference between the diabetic and non-diabetic group was marked in HFA than in PTA. In the diabetic subjects the thresholds of PTA was within 25 dBHL at all frequencies when compared to the thresholds of HFA. Individuals with DM type 2 showed bilateral symmetrical mild hearing loss in HFA and the hearing loss increased with ascending test frequencies from 9,000 to 16,000 Hz. Mild hearing loss in HFA is an indicator for early onset of hearing loss in DM type 2. Hence this present study emphasis the clinical utility of HFA in young adults with DM type 2.

  8. A common gene for juvenile and adult-onset primary open-angle glaucomas confined on chromosome 1q

    Primary open-angle glaucoma (POAG), which causes progressive loss of the visual fields, was subdivided into two groups according to age at onset: (1) chronic open-angle glaucoma (COAG) diagnosed after 40 years and (2) juvenile open-angle glaucoma (JOAG) diagnosed between 3 years of age and early adulthood. A JOAG gene (GLC1A) was recently mapped to chromosome 1q. We studied 142 members of a huge multigenerational French Canadian family affected with autosomal dominant POAG. Either JOAG or COAG was diagnosed with ocular hypertension (OHT), which may lead to POAG. To localize a common disease gene that might be responsible for both glaucoma subsets, we performed linkage analysis considering JOAG and COAG under the same phenotypic category. JOAG/COAG was tightly linked to seven microsatellite markers on chromosome 1q23-q25; a maximum lod score of 6.62 was obtained with AF-M278ye5. To refine the disease locus, we exploited a recombination mapping strategy based on a unique founder effect. The same characteristic haplotype, composed of 14 markers spanning 12 cM between loci D1S196 and D1S212, was recognized in all persons affected by JOAG, COAG, or OHT, but it did not occur in unaffected spouses and in normal family members >35 years of age, except for three obligatory carriers. Key combination events confined the disease region within a 9-cM interval between loci D1S445 and D1S416/D1S480. These observations demonstrate that the GLC1A gene is responsible for both adult-onset and juvenile glaucomas and suggest that the JOAG and COAG categories within this family may be part of a clinical continuum artificially divided at age 40 years. 49 refs., 4 figs., 2 tabs.

    Mutations of the huntingtin protein (HTT) gene underlie both adult-onset and juvenile forms of Huntington’s disease (HD). HTT modulates mitotic spindle orientation and cell fate in mouse cortical progenitors from the ventricular zone. Using human embryonic stem cells (hESC) characterized as carrying mutations associated with adult-onset disease during pre-implantation genetic diagnosis, we investigated the influence of human HTT and of an adult-onset HD mutation on mitotic spindle orientation in human neural stem cells (NSCs) derived from hESCs. The RNAi-mediated silencing of both HTT alleles in neural stem cells derived from hESCs disrupted spindle orientation and led to the mislocalization of dynein, the p150Glued subunit of dynactin and the large nuclear mitotic apparatus (NuMA) protein. We also investigated the effect of the adult-onset HD mutation on the role of HTT during spindle orientation in NSCs derived from HD-hESCs. By combining SNP-targeting allele-specific silencing and gain-of-function approaches, we showed that a 46-glutamine expansion in human HTT was sufficient for a dominant-negative effect on spindle orientation and changes in the distribution within the spindle pole and the cell cortex of dynein, p150Glued and NuMA in neural cells. Thus, neural derivatives of disease-specific human pluripotent stem cells constitute a relevant biological resource for exploring the impact of adult-onset HD mutations of the HTT gene on the division of neural progenitors, with potential applications in HD drug discovery targeting HTT-dynein-p150Glued complex interactions.

    Background Anti-leukotrienes (5-lipoxygenase inhibitors and leukotriene receptors antagonists) serve as alternative monotherapy to inhaled corticosteroids (ICS) in the management of recurrent and/or chronic asthma in adults and children. Objectives To determine the safety and efficacy of anti-leukotrienes compared to inhaled corticosteroids as monotherapy in adults and children with asthma and to provide better insight into the influence of patient and treatment characteristics on the magnitude of effects. Search methods We searched MEDLINE (1966 to Dec 2010), EMBASE (1980 to Dec 2010), CINAHL (1982 to Dec 2010), the Cochrane Airways Group trials register, and the Cochrane Central Register of Controlled Trials (Dec 2010), abstract books, and reference lists of review articles and trials. We contacted colleagues and the international headquarters of anti-leukotrienes producers. Selection criteria We included randomised trials that compared anti-leukotrienes with inhaled corticosteroids as monotherapy for a minimum period of four weeks in patients with asthma aged two years and older. Data collection and analysis Two review authors independently assessed the methodological quality of trials and extracted data. The primary outcome was the number of patients with at least one exacerbation requiring systemic corticosteroids. Secondary outcomes included patients with at least one exacerbation requiring hospital admission, lung function tests, indices of chronic asthma control, adverse effects, withdrawal rates and biological inflammatory markers. Main results Sixty-five trials met the inclusion criteria for this review. Fifty-six trials (19 paediatric trials) contributed data (representing total of 10,005 adults and 3,333 children); 21 trials were of high methodological quality; 44 were published in full-text. All trials pertained to patients with mild or moderate persistent asthma. Trial durations varied from four to 52 weeks. The median dose of inhaled corticosteroids

    Risk factors for rhinitis, asthma and respiratory infections in the home environment were studied by a questionnaire survey. Totally 5775 occupants (≥ 18 years old) from a stratified random sample of multi-family buildings in Sweden participated (46%). 51.0% had rhinitis in the last 3 months (current rhinitis); 11.5% doctor diagnosed asthma; 46.4% respiratory infections in the last 3 months and 11.9% antibiotic medication for respiratory infections in the last 12 months. Associations between home environment and health were analyzed by multiple logistic regression, controlling for gender, age and smoking and mutual adjustment. Buildings constructed during 1960-1975 were risk factors for day time breathlessness (OR = 1.53, 95%CI 1.03-2.29). And those constructed during 1976-1985 had more current rhinitis (OR = 1.43, 95%CI 1.12-1.84) and respiratory infections (OR = 1.46, 95%CI 1.21-1.78). Cities with higher population density had more current rhinitis (p = 0.008) and respiratory infections (p<0.001). Rented apartments had more current rhinitis (OR = 1.23, 95%CI 1.07-1.40), wheeze (OR = 1.20, 95%CI 1.02-1.41), day time breathlessness (OR = 1.31, 95%CI 1.04-1.66) and respiratory infections (OR = 1.13, 95%CI 1.01-1.26). Living in colder parts of the country was a risk factor for wheeze (p = 0.03) and night time breathlessness (p = 0.002). Building dampness was a risk factor for wheeze (OR = 1.42, 95%CI 1.08-1.86) and day time breathlessness (OR = 1.57, 95%CI 1.09-2.27). Building dampness was a risk factor for health among those below 66 years old. Odor at home was a risk factor for doctor diagnosed asthma (OR = 1.49, 95%CI 1.08-2.06) and current asthma (OR = 1.52, 95%CI 1.03-2.24). Environmental tobacco smoke (ETS) was a risk factor for current asthma (OR = 1.53, 95%CI 1.09-2.16). Window panel condensation was a risk factor for antibiotic medication for respiratory infections (OR = 1.41, 95%CI 1.10-1.82). In conclusion, rhinitis, asthma and respiratory infections

    Sleep disturbance has been associated with inflammation and cytokine activity, and we previously described genetic associations between cytokine polymorphisms and sleep maintenance and duration among adults with HIV/AIDS. Although sleep onset insomnia (SOI) is also a commonly reported sleep problem, associations between cytokine biomarkers and SOI have not been adequately studied. The purpose of this study was to describe SOI in relation to cytokine plasma concentrations and gene polymorphisms in a convenience sample of 307 adults (212 men, 72 women, and 23 transgender) living with HIV/AIDS. Based on the Pittsburgh Sleep Quality Index item that asks the time it usually took to fall asleep in the past month, participants were categorized as either >30min to fall asleep (n=70, 23%) or 30min or less to fall asleep (n=237). Plasma cytokines were analyzed, and genotyping was conducted for 15 candidate genes involved in cytokine signaling: interferon-gamma (IFNG), IFNG receptor 1 (IFNGR1), interleukins (IL1R2, IL2, IL4, IL6, IL8, IL10, IL13, IL17A), nuclear factor of kappa light polypeptide gene enhancer in B cells (NFKB1 and NFKB2), and tumor necrosis factor alpha (TNFA). Demographic and clinical variables were evaluated as potential covariates. After adjusting for genomic estimates of ancestry, self-reported race/ethnicity and viral load, SOI was associated with higher IL-13 plasma levels and with six single nucleotide polymorphisms (SNPs): IL1B rs1143642 and rs1143623, IL6 rs4719714, IL13 rs1295686, NFKB1 rs4648110, and TNFA rs2857602. In addition, the IL1B rs1143642 polymorphism was associated with plasma levels of IL-1β in adjusted analyses. This study strengthens the evidence for an association between inflammation and sleep disturbance, particularly self-report of habitual SOI. In this chronic illness population, the cytokine polymorphisms associated with SOI provide direction for future personalized medicine intervention research.

    Background Prior studies have described a higher incidence of dementia or worsening cognitive function in patients with lower levels of kidney function at a single point in time. Objectives To evaluate the association between dynamic measures of renal function ascertained over time with onset of dementia. Design prospective community cohort study. Setting and Participants 2,968 adults aged 65 and older followed for the development of dementia over a median of 6.0 years (interquartile range 3.1–10.1 years). Measurements Time varying measures of renal function were constructed based on a total of 49,340 serum creatinine measurements and included: the average level of estimated glomerular filtration rate (eGFR), eGFR trajectory and variability in eGFR around this trajectory over 5-year exposure windows. The association between these three eGFR exposure measures and risk of dementia was estimated using a Cox regression model adjusted for other patient characteristics. In sensitivity analyses, we also adjusted for time-varying measures of urine protein by dipstick. Results Patients with lower levels of eGFR had a higher incidence of dementia but this did not reach statistical significance in adjusted analyses (omnibus p value=0.14). There were trends toward a higher adjusted incidence of dementia in patients with positive eGFR trajectories (omnibus p value=0.07) and greater variability in eGFR (omnibus p value=0.04) over time. The results of sensitivity analyses, including those in which we included time-varying measures of proteinuria, were consistent with those of the primary analysis. Conclusion Among a community cohort of older adults followed for a median of 6 years, we did not find strong associations between measures of kidney disease severity and progression and incident dementia.

    Neonatal rats reared on high-carbohydrate (HC) milk formula developed chronic hyperinsulinemia and adult-onset obesity due to programming of islets and the hypothalamic energy circuitry. In this study, calorie restriction by pair-feeding was imposed on HC male rats (HC/PF) to normalize food intake similar to that of mother-fed (MF) rats from weaning until postnatal day 140. A group of HC/PF rats was switched over to ad libitum feeding (HC/PF/AL) from days 90 to 140. Pair-feeding reduced body weight gains and serum insulin and leptin levels in HC/PF rats compared with HC rats, but these parameters were restored to HC levels in the HC/PF/AL rats after ad libitum feeding. Interestingly, the heightened insulin secretory response of isolated islets from adult HC/PF and HC/PF/ AL rats to glucose, acetylcholine, and oxymetazoline were not significantly different from the responses of islets from HC rats. Similarly, the expression of neuropeptide Y and proopiomelanocortin in the hypothalamus was not significantly different among HC, HC/PF, and HC/PF/AL rats. Expression of the leptin receptor in the hypothalami from the HC, HC/PF, and HC/PF/AL rats mirrored that of serum leptin, whereas suppressor of cytokine signaling 3 (Socs3) expression remained high in these three groups. The results indicate that, although calorie restriction resulted in reduction in body weight gain and normalized the serum hormonal pattern, the programed predisposition for the hypersecretory capacity of islets and the hypothalamic hyperphagic response in the HC rats could not be permanently overcome by the pair-feeding imposed on HC rats.

    Phospholipase D2 (PLD2) is an enzyme that produces phosphatidic acid (PA), a lipid messenger molecule involved in a number of cellular events including, through its membrane curvature properties, endocytosis. The PLD2 knock out (PLD2KO) mouse has been previously reported to be protected from insult in a model of Alzheimer's disease. We have further analysed a PLD2KO mouse using mass spectrophotometry of its lipids and found significant differences in PA species throughout its brain. We have examined the expression pattern of PLD2 which allowed us to define which region of the brain to analyse for defect, notably PLD2 was not detected in glial-rich regions. The expression pattern lead us to specifically examine the mitral cells of olfactory bulbs, the Cornus Amonis (CA) regions of the hippocampus and the Purkinje cells of the cerebellum. We find that the change to longer PA species correlates with subtle architectural defect in the cerebellum, exemplified by ectopic Purkinje cells and an adult-onset deficit of olfaction. These observations draw parallels to defects in the reelin heterozygote as well as the effect of high fat diet on olfaction. PMID:27658289

    Hemophagocytic lymphopcytosis (HLH) is a life-threatening condition. It can occur either as primary form with genetic defects or secondary to other conditions, such as hematological or autoimmune diseases. Certain triggering factors can predispose individuals to the development of HLH. We report the case of a 25-year-old male patient who was diagnosed with HLH in the context of adult-onset Still's disease (AOSD) during a primary infection with Epstein-Barr virus (EBV). During therapy with anakinra and dexamethasone, he was still symptomatic with high-spiking fevers, arthralgia, and sore throat. His laboratory values showed high levels of ferritin and C-reactive protein. His condition improved after the addition of rituximab and cyclosporine to his immunosuppressive regimen with prednisolone and anakinra. This combination therapy led to a sustained clinical and serological remission of his condition. While rituximab has been used successfully for HLH in the context of EBV-associated lymphoma, its use in autoimmune diseases is uncommon. We hypothesize that the development of HLH was triggered by a primary EBV infection and that rituximab led to elimination of EBV-infected B-cells, while cyclosporine ameliorated the cytokine excess. We therefore propose that this combination immunosuppressive therapy might be successfully used in HLH occurring in the context of autoimmune diseases. PMID:28018698

    We report the case of a 36-year-old Japanese woman with nephrotic syndrome due to membranoproliferative glomerulonephritis (MPGN) Type I diagnosed after a 5-year history of periodic fever syndrome (PFS). Hypocomplementemia and elevation of anti-proteinase 3 anti-neutrophil cytoplasmic autoantibody (PR3-ANCA) were observed. HIV, and hepatitis B and C serology were negative. Nephrotic syndrome and periodic fever did not respond to oral steroid and intravenous steroid pulse therapies combined with cyclosporine, dipyridamole, warfarin and losartan. We tried immunotherapy using rituximab, a human-mouse chimeric monoclonal antibody directed against the CD20 antigen on mature B cells. This therapeutic approach led to improvement of renal function and remission of nephrotic syndrome and hypocomplementemia. However, it did not have a beneficial effect on periodic fever. Suspecting adult-onset hereditary PFS, we analyzed her genetic alteration of MEFV and TNFRSF1A genes. A rare genotype in intron 6 of TNFRSF1A was revealed. The etiological relationship between periodic fever and MPGN is discussed. Rituximab is a hopeful choice of induction therapy for refractory MPGN. PMID:23197963

    We evaluated clinical characteristics and prognosis for adult-onset Still's disease (AOSD) complicated by hemophagocytic lymphohistiocytosis (HLH). We retrospectively identified cases of AOSD with (n = 10) and without (n = 305) HLH complications. We reviewed their medical records, completed follow-up through outpatient clinic and telephone interviews, and analyzed their clinical symptoms, signs, laboratory test results, treatments, and prognosis. More AOSD patients with HLH developed hepatomegaly, bleeding, serositis, and neurologic symptoms than those without HLH, and they more commonly presented with leukopenia, thrombocytopenia, severe anemia, severe liver function abnormalities, decreased fibrinogen, elevated immunoglobulin, and bone marrow hemophagocytosis. The ten patients with AOSD complicated by HLH were treated with high-dose steroids or pulse steroid therapy, and eight of them also received cytotoxic drugs, while biological agents showed poor response. Follow-up results indicated that AOSD patients overall had good prognosis, while those with HLH showed worse prognosis, including higher relapse and readmission rates and increased mortality. In patients with AOSD, unexplained decreased blood cells, severe liver dysfunction, and/or hemophagocytosis in the bone marrow should be considered as signs of HLH complication. Patients with AOSD complicated by HLH have worse prognosis and higher relapse rates compared to AOSD patients without HLH complications. Thus, these patients should undergo frequent and careful follow-up.

    We describe detailed clinical, biochemical, neuroimaging and neuropathological features in adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), encompassing hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) and pigmentary orthochromatic leukodystrophy (POLD), linked to colony-stimulating factor 1 receptor (CSF1R) mutations in four Korean cases. Clinical, biochemical, neuroimaging and neuropathological findings were obtained by direct evaluation and from previous medical records. The genetic analysis of the CSF1R gene was done in two autopsy-confirmed ALSP cases and two cases where ALSP was suspected based on the clinical and neuroimaging characteristics. We identified two known mutations: c.2342C>T (p.A781V) in one autopsy-proven HDLS and clinically ALSP-suspected case and c.2345G>A (p.R782H) in another autopsy-proven POLD case. We also found a novel mutation (c.2296A>G; p.M766V) in a patient presenting with hand tremor, stuttering and hesitant speech, and abnormal behavior whose father died from a possible diagnosis of spinocerebellar ataxia. To the best of our knowledge, this is the first documented ALSP-linked CSF1R mutation in Korea and supports the suggestion that HDLS and POLD, with pathological characteristics that are somewhat different but which are caused by CSF1R mutations, are the same spectrum of disease, ALSP.

    We present a two-generation family consisting of a father and two daughters, who had an adult-onset leukodystrophy characterized by widespread destruction of cerebral white matter with neuroaxonal spheroids. The mode of inheritance appears to be autosomal dominant. All three patients presented with a variety of motor and cognitive symptoms, including frontal lobe signs, 4-7 years before death. Each followed a chronic course until death at ages 39, 46, and 51. At autopsy, the white matter loss was widespread but most prominent in the cerebrum with descending corticospinal tract degeneration and relative sparing of subcortical U-fibers. Pigmented glial cells were present, most of which appear to be macrophages, but inconstantly Prussian blue-positive. This disease is consistent with published reports of hereditary diffuse leukoencephalopathy with spheroids (HDLS). However, a review of the literature and a personal review of the neuropathology of the original case of the pigmentary type of orthochromatic leukodystrophy (POLD) reveal overlapping clinical and neuropathologic features between these two previously distinct entities, suggesting a common pathogenetic and perhaps etiological relationship between the two.

    Adult-onset Still's disease (AOSD), as a category of connective tissue diseases, has about 5∼9% of fever of unknown origin (FUO) cases. Diagnosis of AOSD was challenging because of its nonspecific characteristics. The present study analyzed clinical manifestations and laboratory findings in a series of patients with AOSD from eastern China. Medical records of 61 patients admitted with FUO and with a discharge diagnosis of AOSD were retrospectively evaluated and analyzed with special focus on clinical manifestations and laboratory findings. Compared with previous reports, most features of our patients had a similar incidence rate. Rash (79%), arthralgia (80%), and sore throat (84%) were the most frequent clinical manifestations in our series. Leukocytosis (80%), elevated ESR (98%) and CRP (100%), negative ANA (90%) and RF (93%), and high ferritin level (94%) were the most sensitive laboratory findings in our patients. AOSD was not a rare reason of FUO in eastern China. Fever, arthralgia, rash, sore throat, leukocytosis, neutrophilia, elevated ESR and CRP, negative ANA and RF, and high ferritin level were the most common clinical features in our series. The lack of highly specific characteristic makes the diagnosis of AOSD difficult compared with other diseases in FUO.

    Adult-onset Still's disease (AOSD) remains a perplexing, difficult to diagnose clinical entity, with clinical characteristics that are often broad and encountered in numerous other clinical entities. This vague clinical presentation is depicted in the commonly used diagnostic criteria, as the ones by Yamaguchi and Fautrel. The authors sought to investigate how diagnostic criteria apply in a series of 22 new cases of AOSD patients presenting with fever of unknown origin (FUO) and diagnosed at the Internal Medicine Department of Hatzikosta General Hospital of Ioannina, Greece. The aims of the study were: (1) to study the incidence of AOSD and (2) to retrospectively apply different classifications to the data of these patients in search of a more efficient way of diagnosing these patients in the future. The annual incidence of AOSD was estimated at two new cases per 10(5). The clinical manifestations of the patients are discussed, with an emphasis on specific manifestations being considered as criteria by Yamaguchi and Fautrel classifications. Four patients exhibited markedly increased serum D: -dimers, a finding of which the potential pathophysiologic implications are discussed. Serum ferritin levels have additive values, both for diagnostic and cost-reduction purposes in cases presenting as FUO; serum ferritin values are not included in any diagnostic set of criteria at present. The finding of high levels of D-dimers in AOSD needs further studies.

    Late-onset hemorrhagic cystitis (LHC) after hematopoietic stem cell transplantation (HSCT) is mainly caused by viral infections. We retrospectively analyzed the records of 141 Japanese adult patients who underwent a first allogeneic HSCT from 1995 to 2002. In all, 19 patients developed LHC a median of 51 days after HSCT. Adenovirus (AdV) was detected in the urine of 10 LHC patients, of whom eight had AdV type 11. Five of the six available serum samples from these patients were also positive for AdV type 11, but the detection of AdV in serum was not associated with a worse outcome. Male sex and the development of grade II-IV acute graft-versus-host disease were identified as independent significant risk factors for LHC. Male predominance was detected in LHC after HSCT, as has been previously shown in children with AdV-induced acute HC. The detection of AdV DNA in serum did not predict a poor outcome.

    2012-01-01

    Background Asthma is a frequent chronic respiratory disease in both children and adults. However, few data on asthma prevalence are available in Portugal. The Portuguese National Asthma Survey is the first nationwide study that uses standardized methods. We aimed to estimate the prevalence of current asthma in the Portuguese population and to assess the association between ‘Current asthma’ and comorbidities such as upper airways disease. Methods A cross-sectional, population-based, telephone interview survey including all municipalities of Portugal was undertaken. Participants were randomly selected to answer a questionnaire based on the Portuguese version of the GA2LEN survey. ‘Current asthma’ was defined as self-reported lifetime asthma and at least one of 3 symptoms in the last 12 months: wheezing, waking with breathlessness or having an asthma attack. Results Data were obtained for 6 003 respondents, with mean age of 38.9 (95%CI 38.2-39.6) years and 57.3% females. In the Portuguese population, the prevalence of ‘Current asthma’ was 6.8% (95%CI 6.0-7.7) and of ‘Lifetime asthma’ was 10.5% (95%CI 9.5-11.6) Using GA2LEN definition for asthma, our prevalence estimate was 7.8% (95%CI 7.0-8.8). Rhinitis had a strong association with asthma (Adjusted OR 3.87, 95%CI 2.90-5.18) and the association between upper airway diseases and asthma was stronger in patients with both rhinitis and sinusitis (Adjusted OR 13.93, 95%CI 6.60-29.44). Conclusions Current asthma affects 695 000 Portuguese, with a prevalence of 6.8%. People who reported both rhinitis and sinusitis had the highest risk of having asthma. PMID:22931550

    OBJECTIVE: To develop review criteria to assess the quality of care for three major chronic diseases: adult asthma, stable angina, and non- insulin dependent diabetes mellitus. SUBJECTS AND METHODS: Modified panel process based upon the RAND/UCLA (University College of Los Angeles) appropriateness method. Three multiprofessional panels made up of general practitioners, hospital specialists, and practice nurses. RESULTS: The RAND/UCLA appropriateness method of augmenting evidence with expert opinion was used to develop criteria for the care of the three conditions. Of those aspects of care which were rated as necessary by the panels, only 26% (16% asthma, 10% non-insulin dependent diabetes, 40% angina) were subsequently rated by the panels as being based on strong scientific evidence. CONCLUSION: The results show the importance of a systematic approach to combining evidence with expert opinion to develop review criteria for assessing the quality of three chronic diseases in general practice. The evidence base for the criteria was often incomplete, and explicit methods need to be used to combine evidence with expert opinion where evidence is not available. PMID:10557672

    Risk factors for asthma, allergy and eczema were studied in a stratified random sample of adults in Stockholm. In 2005, 472 multifamily buildings (10,506 dwellings) were invited (one subject/dwelling) and 7,554 participated (73%). Associations were analyzed by multiple logistic regression, adjusting for gender, age, smoking, country of birth, income and years in the dwelling. In total, 11% had doctor's diagnosed asthma, 22% doctor's diagnosed allergy, 23% pollen allergy and 23% eczema. Doctor's diagnosed asthma was more common in dwellings with humid air (OR = 1.74) and mould odour (OR = 1.79). Doctor's diagnosed allergy was more common in buildings with supply exhaust air ventilation as compared to exhaust air only (OR = 1.45) and was associated with redecoration (OR = 1.48) and mould odour (OR = 2.35). Pollen allergy was less common in buildings using more energy for heating (OR = 0.75) and was associated with humid air (OR = 1.76) and mould odour (OR = 2.36). Eczema was more common in larger buildings (OR 1.07) and less common in buildings using more energy for heating (OR = 0.85) and was associated with water damage (OR = 1.47), humid air (OR = 1.73) and mould odour (OR = 2.01). Doctor's diagnosed allergy was less common in buildings with management accessibility both in the neighbourhood and in larger administrative divisions, as compared to management in the neighbourhood only (OR = 0.49; 95% CI 0.29–0.82). Pollen allergy was less common if the building maintenance was outsourced (OR = 0.67; 95% CI 0.51–0.88). Eczema was more common when management accessibility was only at the division level (OR = 1.49; 95% CI 1.06–2.11). In conclusions, asthma, allergy or eczema were more common in buildings using less energy for heating, in larger buildings and in dwellings with redecorations, mould odour, dampness and humid air.

    Occupational asthma (OA) is the most common of all occupational lung diseases in industrialized countries and its prevalence has been rising steadily. It is estimated that occupational factors account for one out of six cases of adult asthmatic patients causing significant morbidity, disability and costs. Due to its high prevalence and substantial health and socio-economic impacts OA represents a significant public health concern. OA can be divided into allergic and non allergic asthma. Allergic OA is further divided into IgE mediated and non IgE mediated. Baker's asthma (BA), is the leading cause of IgE mediated OA caused by high molecular weight antgens in industrialized countries. Innovations in the baking industry during the last few decades have led to the introduction of new allergens inducing OA. OA is potentially preventable, through early diagnosis and exposure cessation interventions. Thus, clinicians should consider the occupational history in every adult patient presenting with newly diagnosed asthma.

    Background In asthmatic patients inadequately controlled on inhaled corticosteroids and/or those with moderate persistent asthma, two main options are recommended: the combination of a long-acting inhaled ß2 agonist (LABA) with inhaled corticosteroids (ICS) or use of a higher dose of inhaled corticosteroids. Objectives To determine the effect of the combination of long-acting ß2 agonists and inhaled corticosteroids compared to a higher dose of inhaled corticosteroids on the risk of asthma exacerbations, pulmonary function and on other measures of asthma control, and to look for characteristics associated with greater benefit for either treatment option. Search methods We identified randomised controlled trials (RCTs) through electronic database searches (MEDLINE, EMBASE and CINAHL), bibliographies of RCTs, clinical trial registries and correspondence with manufacturers until May 2008. Selection criteria RCTs that compared the combination of inhaled LABA and ICS to a higher dose of inhaled corticosteroids, in children and adults with asthma. Data collection and analysis Two authors independently assessed methodological quality and extracted data. We obtained confirmation from the trialists when possible. The primary endpoint was the number of patients experiencing one or more asthma exacerbations requiring oral corticosteroids. Main results This review included 48 studies (15,155 participants including 1155 children and 14,000 adults). Participants were inadequately controlled on their current ICS regimen, experiencing ongoing symptoms and with generally moderate (FEV1 60% to 79% of predicted) airway obstruction. The studies tested the combination of salmeterol or formoterol with a median dose of 400 mcg/day of beclomethasone or equivalent (BDP-eq) compared to a median of 1000 mcg/day of BDP-eq, usually for 24 weeks or less. There was a statistically significantly lower risk of exacerbations requiring systemic corticosteroids in patients treated with LABA and ICS

    Very frequently we have to deal with children who follow specific treatment to combat their repetitive episodes of breathing difficulty and wheezing. In many cases, they suffer from asthma. Hippocrates defined asthma as "the condition which causes an excessive narrowing of the bronchi after a reaction with a provocative stimulus which usually does not produce any effect".

    PubMed

    Asthma is characterized by reversible airway obstruction, airway hyperresponsiveness, and airway inflammation. Although our understanding of its pathophysiological mechanisms continues to evolve, the relative contributions of airway hyperresponsiveness and inflammation are still debated. The first mechanism identified as important for asthma was bronchial hyperresponsiveness. In a second step, asthma was recognized also as an inflammatory disease, with chronic inflammation inducing structural changes or remodeling. However, persistence of airway dysfunction despite inflammatory control is observed in chronic severe asthma of both adults and children. More recently, a potential role for epithelial-mesenchymal communication or transition is emerging, with epithelial injury often resulting in a self-sustaining phenotype of wound repair modulation by activation/reactivation of the epithelial-mesenchymal trophic unit, suggesting that chronic asthma can be more than an inflammatory disease. It is noteworthy that the gene-environmental interactions critical for the development of a full asthma phenotype involve processes similar to those occurring in branching morphogenesis. In addition, a central role for airway smooth muscle in the pathogenesis of the disease has been explored, highlighting its secretory function as well as different intrinsic properties compared to normal subjects. These new concepts can potentially shed light on the mechanisms underlying some asthma phenotypes and improve our understanding of the disease in terms of the therapeutic strategies to be applied. How we understand asthma and its mechanisms along time will be the focus of this overview.

    Background While exposure to outdoor particulate matter (PM) has been associated with poor asthma outcomes, few studies have investigated the combined effects of outdoor and indoor PM (including secondhand tobacco smoke). Objective To examine the associations between PM and asthma outcomes. Methods We analyzed data from a cohort of adults with asthma and rhinitis (n=302; 82% both conditions; 13% asthma only; 5% rhinitis alone) including measures of home PM, tobacco smoke exposure (hair nicotine and self-report), ambient PM from regional monitoring, distance to roadway, and season (wet or dry). The outcomes of interest were frequent respiratory symptoms and forced expiratory volume in 1 second (FEV1) below the lower limit of normal (NHANES reference values). Multivariable regression analyses examined the associations (Odds Ratio [OR] and 95% Confidence Interval [95%CI]) between exposures and these outcomes, adjusted by sociodemographic characteristics. Results In adjusted analyses of each exposure, the highest tertile of home PM and season of interview were associated with increased odds for more frequent respiratory symptoms (OR=1.64 95%CI: [1.00, 2.69] and OR = 1.66 95%CI: [1.09, 2.51]). The highest tertile of hair nicotine was significantly associated with FEV1 below the lower limit of normal (OR=1.80 95%CI: [1.00, 3.25]). In a model including home PM, ambient PM, and hair nicotine, and season, only two associations remained strong: hair nicotine with FEV1 below the lower limit of normal and season of measurement (dry, April-October) with increased respiratory symptoms (OR=1.85 95%CI: [1.00, 3.41] and OR = 1.54 95%CI: [1.0, 2.37]). When that model was stratified by sex, the highest tertiles of ambient PM and hair nicotine were associated with FEV1 below the lower limit of normal among women (OR=2.23 95%CI: [1.08, 4.61] and OR=2.90 95% CI: [1.32, 6.38]), but not men. The highest tertile of hair nicotine was also associated with increased respiratory symptoms in

    Growth hormone (GH) and insulin-like growth factor-I (IGF-I) provide trophic support during development and also appear to influence cell structure, function and replacement in the adult brain. Recent studies demonstrated effects of the GH/IGF-I axis on adult neurogenesis, but it is unclear whether the GH/IGF-I axis influences glial turnover in the normal adult brain. In the current study, we used a selective model of adult-onset GH and IGF-I deficiency to evaluate the role of GH and IGF-I in regulating glial proliferation and survival in the adult corpus callosum. GH/IGF-I-deficient dwarf rats of the Lewis strain were made GH/IGF-I replete via twice daily injections of GH starting at postnatal day 28 (P28), approximately the age at which GH pulse amplitude increases in developing rodents. GH/IGF-I deficiency was initiated in adulthood by removing animals from GH treatment. Quantitative analyses revealed that adult-onset GH/IGF-I deficiency decreased cell proliferation in the white matter and decreased the survival of newborn oligodendrocytes. These findings are consistent with the hypothesis that aging-related changes in the GH/IGF-I axis produce deficits in ongoing turnover of oligodendrocytes, which may contribute to aging-related cognitive changes and deficits in remyelination after injury.

    BACKGROUND—It has been reported that intranasal corticosteroids can influence bronchial hyperresponsiveness (BHR) in asthmatic subjects with seasonal rhinitis. The purpose of the present study was to evaluate the effect of intranasal fluticasone propionate and beclomethasone dipropionate on BHR and bronchial calibre (forced expiratory volume in one second, FEV1) in children and young adults with seasonal rhinitis and mild asthma during two consecutive grass pollen seasons.
METHODS—In the first pollen season 25 patients aged 8-28 years were included in a double blind, placebo controlled study. The active treatment group used fluticasone aqueous spray 200 µg once daily. In the second pollen season 72 patients aged 8-28 years participated in a double blind, placebo controlled study of a similar design to that of the previous year except that an additional treatment group of patients using beclomethasone 200 µg twice daily was included. FEV1 was measured before and after three and six weeks of treatment; BHR to methacholine (PD20) was measured before and after six weeks of treatment.
RESULTS—In the first season the mean (SD) logPD20 of the patients decreased significantly both in the fluticasone group (from 2.43(0.8) µg to 1.86 (0.85) µg) and in the placebo group (from 2.41(0.42) µg to 1.87 (0.78) µg) without any intergroup difference in the change in logPD20. In the second pollen season the mean logPD20 in the fluticasone, beclomethasone, and placebo groups did not change significantly.
CONCLUSIONS—Intranasal steroids did not influence BHR during two grass pollen seasons in children and young adults with seasonal rhinitis and mild asthma.

    Risk factors for rhinitis, asthma and respiratory infections in the home environment were studied by a questionnaire survey. Totally 5775 occupants (≥18 years old) from a stratified random sample of multi-family buildings in Sweden participated (46%). 51.0% had rhinitis in the last 3 months (current rhinitis); 11.5% doctor diagnosed asthma; 46.4% respiratory infections in the last 3 months and 11.9% antibiotic medication for respiratory infections in the last 12 months. Associations between home environment and health were analyzed by multiple logistic regression, controlling for gender, age and smoking and mutual adjustment. Buildings constructed during 1960–1975 were risk factors for day time breathlessness (OR = 1.53, 95%CI 1.03–2.29). And those constructed during 1976–1985 had more current rhinitis (OR = 1.43, 95%CI 1.12–1.84) and respiratory infections (OR = 1.46, 95%CI 1.21–1.78). Cities with higher population density had more current rhinitis (p = 0.008) and respiratory infections (p<0.001). Rented apartments had more current rhinitis (OR = 1.23, 95%CI 1.07–1.40), wheeze (OR = 1.20, 95%CI 1.02–1.41), day time breathlessness (OR = 1.31, 95%CI 1.04–1.66) and respiratory infections (OR = 1.13, 95%CI 1.01–1.26). Living in colder parts of the country was a risk factor for wheeze (p = 0.03) and night time breathlessness (p = 0.002). Building dampness was a risk factor for wheeze (OR = 1.42, 95%CI 1.08–1.86) and day time breathlessness (OR = 1.57, 95%CI 1.09–2.27). Building dampness was a risk factor for health among those below 66 years old. Odor at home was a risk factor for doctor diagnosed asthma (OR = 1.49, 95%CI 1.08–2.06) and current asthma (OR = 1.52, 95%CI 1.03–2.24). Environmental tobacco smoke (ETS) was a risk factor for current asthma (OR = 1.53, 95%CI 1.09–2.16). Window pane condensation was a risk factor for antibiotic medication for respiratory infections (OR

    The contribution of workplace exposures to the prevalence of asthma in adults has been minimized in the epidemiology of this illness. Analysis of the 1978 Social Security Disability Survey provides a population-based assessment as a novel approach utilizing self-attributed, occupationally related asthma as a measure of disease. Of 6063 respondents, 468 (7.7 percent) identified asthma as a personal medical condition; 72 (1.2 percent (15.4 percent of all those with asthma)) attributed it to workplace exposures. These subjects were older and included more men and cigarette smokers than groups of both asthmatic and nonasthmatic subjects. The relative risk for occupationally attributed asthma was elevated among industrial and agricultural workers as compared with white collar and service occupations. Analysis of disability benefit status did not indicate that this introduced major reporting bias in this survey. This study suggests that occupational factors may have a greater role in adult asthma than previously thought.

    Tiotropium solution for inhalation (Spiriva Respimat - Boehringer Ingelheim) is the first long-acting muscarinic antagonist to be marketed in the UK for the management of asthma. It is licensed as add-on maintenance bronchodilator treatment in adults with asthma who are using an inhaled corticosteroid (≥800μg budesonide/day or equivalent) and a long-acting beta2 agonist, and who have had one or more severe exacerbations in the previous year. This corresponds to use at step 4 of both the British asthma guideline and the Global Initiative for Asthma (GINA) strategy for the treatment of asthma in adults. Here we consider the evidence for tiotropium in the management of asthma and whether it offers any advantages over existing therapeutic options at step 4.

    McGRATH, Ryan P; Whitehead, James R; Caine, Dennis J

    Until recently, the scientific community believed that post-exercise stretching could reduce delayed onset muscle soreness (DOMS), but recent reviews of studies on the topic have concluded that pre- or post-exercise static stretching has no effect on mitigating DOMS. However, the effect of proprioceptive neuromuscular facilitation (PNF) post-exercise stretching on preventing DOMS has not been adequately studied. The purpose of this study was to determine the effect of post-exercise PNF stretching on DOMS. Young adult participants (N=57) were randomly assigned to a PNF stretching group (n=19), a static stretching group (n=20), and to a no-stretching control group (n=18). All participants completed exercise designed to induce DOMS prior to post-exercise experimental stretching protocols. Participants rated their soreness level on a pain scale 24 and 48 hours post-exercise. A 3 × 2 mixed ANOVA showed there was an effect for time (p<.01). Post hoc testing revealed that DOMS pain significantly decreased (p<.05) from 24 to 48 hours post-exercise for the PNF and control groups, but not for the static stretching group. Other analyses revealed a significant correlation (r=.61, p<.01) between the pre- and post-exercise stretch scores and the 48 hour post-exercise pain score for the PNF group. Consistent with the results of previous research on post-exercise static stretching, these results indicate that post-exercise PNF stretching also does not prevent DOMS. However, the correlation analysis suggests it is possible the pre-stretch muscle contractions of the post-exercise PNF protocol may have placed a load on an already damaged muscle causing more DOMS for some participants.

    Adult orbital xanthogranulomatous diseases are rare entities and encompass a group of disorders with varying manifestations that are poorly understood. Taken as a group, there are non-Langerhans histiocytic disorders (type II) that are diagnosed histologically by the presence of foamy histiocytes, Touton giant cells, and varying degrees of fibrosis. Based on the accompanying systemic associations, there are 4 main categories of adult xanthogranulomatous disease: adult-onset xanthogranuloma, adult-onset asthma and periocular xanthogranuloma, necrobiotic xanthogranuloma, and Erdheim-Chester disease. Herein, we discuss the etiopathogenesis, systemic associations, methods of diagnosis, and treatment options for these disorders.

    Difficult asthma is a major issue in pulmonary medicine today because of its cost for patients and society. Difficult asthma is asthma that remains uncontrolled despite optimal specialist management. The validity of the diagnosis must be reconsidered in these cases: associated or differential diagnoses may be involved in the lack of control, and it is always necessary to assess the patient's treatment adhesion. Sufficient time--at least a year--must be taken to get to know the patient and to meet the objectives set. The standard asthma therapies should be tested objectively. Severe asthma is the reality of difficult asthma that endures despite a reaffirmed diagnosis, optimal compliance and controlled comorbidities. Better knowledge is needed of the pathophysiology of these patients' asthma. Improved knowledge of these phenotypes will make it possible to develop innovative treatments. They will need to be validated in clinical research for subsequent use that is wider but more rational because targeted at phenotypes likely to benefit from them.

    Delayed sleep phase disorder is characterized by a delay in the timing of the major sleep period relative to conventional norms. The sleep period itself has traditionally been described as normal. Nevertheless, it is possible that sleep regulatory mechanism disturbances associated with the disorder may affect sleep duration and/or architecture. Polysomnographic data that may shed light on the issue are scarce. Hence, the aim of this study was to examine polysomnographic measures of sleep in adolescents and young adults with delayed sleep phase disorder, and to compare findings to that of healthy controls. A second aim was to estimate dim light melatonin onset as a marker of circadian rhythm and to investigate the phase angle relationship (time interval) between dim light melatonin onset and the sleep period. Data from 54 adolescents and young adults were analysed, 35 diagnosed with delayed sleep phase disorder and 19 healthy controls. Results show delayed timing of sleep in participants with delayed sleep phase disorder, but once sleep was initiated no group differences in sleep parameters were observed. Dim light melatonin onset was delayed in participants with delayed sleep phase disorder, but no difference in phase angle was observed between the groups. In conclusion, both sleep and dim light melatonin onset were delayed in participants with delayed sleep phase disorder. The sleep period appeared to occur at the same circadian phase in both groups, and once sleep was initiated no differences in sleep parameters were observed.

    Introduction The role of shunt placement is to divert cerebrospinal fluid from within the ventricles to an alternative location in the setting of hydrocephalus. One of the rare shunt complications is distal catheter migration, and various body sites have been reported, including the scrotum. Although cases of scrotal migration of distal catheter have been reported in pediatric patients, cases in adult patients are rare due to obliterated processus vaginalis. Furthermore, there has not been a case reported for scrotal migration in an adult at an early onset. Presentation of case 65-year-old male underwent shunt placement for normal-pressure hydrocephalus-like symptoms. On post-operative day seven patient developed right testicular edema, for which ultrasound was performed, revealing hydrocele along with the presence of distal catheter in the scrotum. On post-operative day nine patient underwent distal catheter trimming via laparoscopic approach with general surgery, with post-operative imaging showing satisfactory location of distal catheter in the peritoneal cavity. Discussion/Conclusion Early onset of distal catheter migration into scrotum in an adult male is a unique case, as most cases are reported in pediatric patients, and it is the first case reported in the English literature to have occurrence at an early onset during the peri-operative period. As our case demonstrates, early occurrence and detection of scrotal migration of the distal catheter prevent shunt malfunction. Prompt surgical management of catheter repositioning is therefore recommended to avoid the risk of further complications. PMID:25553524

    Background Outcomes of pulmonary physiology have a central place in asthma clinical research. Objective At the request of National Institutes of Health (NIH) institutes and other federal agencies, an expert group was convened to provide recommendations on the use of pulmonary function measures as asthma outcomes that should be assessed in a standardized fashion in future asthma clinical trials and studies to allow for cross-study comparisons. Methods Our subcommittee conducted a comprehensive search of PubMed to identify studies that focused on the validation of various airway response tests used in asthma clinical research. The subcommittee classified the instruments as core (to be required in future studies), supplemental (to be used according to study aims and in a standardized fashion), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop in March 2010 and finalized in September 2011. Results A list of pulmonary physiology outcomes that applies to both adults and children older than 6 years was created. These outcomes were then categorized into core, supplemental, and emerging. Spirometric outcomes (forced expiratory volume in 1 second [FEV1], forced vital capacity [FVC], and FEV1/FVC) are proposed as core outcomes for study population characterization, for observational studies, and for prospective clinical trials. Bronchodilator reversibility and pre- and post-bronchodilator FEV1 also are core outcomes for study population characterization and observational studies. Conclusions The subcommittee considers pulmonary physiology outcomes of central importance in asthma and proposes spirometric outcomes as core outcomes for all future NIH-initiated asthma clinical research.

    The aim was to determine dietary patterns and investigate their associations with incident asthma, current asthma and frequent asthma exacerbations. Dietary habits and asthma data were collected from the large E3N study (French women, mostly teachers). Of 54,672 women followed-up in 2003, 2,634 reported ever adulthood asthma, 1,063 current asthma, 206 frequent asthma attacks (≥1/week), and 628 asthma-onset between 1993 and 2003. Using principal component analysis, three dietary patterns were identified: ‘prudent’ pattern (fruits and vegetables), ‘Western’ pattern (pizza/salty pies, dessert and cured meats) and ‘nuts and wine’ pattern. Pattern scores were categorized into tertiles and the incidence and prevalence of asthma compared between tertiles. After adjustment for confounders, no association of dietary patterns was observed with incident, ever or current asthma. The ‘Western’ pattern was associated with an increased risk of reporting frequent asthma attacks (OR for highest vs. lowest tertile [95% CI]=1.79 [1.11–3.73], p for trend=0.01). Increasing scores of the ‘nuts and wine’ pattern were associated with a decreased risk of reporting frequent asthma attacks (OR for highest vs. lowest tertile [95% CI]=0.65 [0.31,0.96], p for trend=0.02). Results suggest that overall diet could be involved in frequent asthma exacerbations, one aspect of asthma severity. PMID:18829673

    Asthma prevalence in children has increased 58% since 1980. Mortality has increased by 78%. The burden of the disease is most acute in urban areas and racial/ethnic minority populations. Hospitalization and morbidity rates for nonwhites are more than twice those for whites. Asthma is characterized by recurrent wheezing, breathlessness, chest tightness, and coughing. Research in the past decade has revealed the importance of inflammation of the airways in asthma and clinical treatment to reduce chronic inflammation. Asthma is associated with production of IgE to common environmental allergens including house dust mite, animal dander, cockroach, fungal spores, and pollens. Some interventions to reduce symptoms through control of dust mite and animal dander have had positive results. Control of symptoms through interventions to reduce exposures to cockroach antigen has not been reported. Studies illustrating causal effects between outdoor air pollution and asthma prevalence are scant. Increases in asthma prevalence have occurred at the same time as general improvements in air quality. However, air quality appears to exacerbate symptoms in the child who already has the disease. Decreased pulmonary function has been associated with exposure to particulates and bronchial hyperresponsiveness to smoke, SO(2) and NO(2). Symptoms have been correlated with increased levels of respirable particulates, ozone, and SO(2). Interventions that reduce the negative outcomes in asthma associated with outdoor environmental factors have not been reported. Control of asthma in children will entail the collaborative efforts of patients, family, clinical professionals, and school personnel, as well as community-wide environmental control measures and conducive national and local policies based on sound research.

    Asthma is a chronic inflammatory disorder of the airways characterized by airflow obstruction, bronchial hyperreactivity, and underlying inflammation. Two common reasons asthmatics fail standard therapy are incorrect diagnosis and failure to recognize underlying contributing factors. A correct diagnosis of asthma is of great importance to military practitioners since misdiagnosis or uncontrolled asthma affects an individual's operational readiness or determines whether one can receive a medical waiver to enlist in military service. This article presents four cases of patients with dyspnea that have conditions which mimic asthma or complicate asthma management: vocal cord dysfunction misdiagnosed as asthma, respiratory bronchiolitis interstitial lung disease mistaken as asthma, difficult-to-control asthma because of bronchiectasis and allergic bronchopulmonary aspergillosis, and difficult and fatal asthma. Asthma is contrasted to other respiratory disorders, and an outlined approach to asthma diagnosis and management is presented using the Global Initiative for Asthma guidelines.

    Progression to severe organ involvement due to dengue infection has been associated with severe dengue disease, intensive care treatment, and mortality. However, there is a lack of understanding of the impact of pre-existing comorbidities and other risk factors of severe organ involvement among dengue adults. The aim of this retrospective case-control study is to characterize and identify risk factors that predispose dengue adults at risk of progression with severe organ involvement. This study involved 174 dengue patients who had progressed with severe organ involvement and 865 dengue patients without severe organ involvement, matched by the year of presentation of the cases, who were admitted to Tan Tock Seng Hospital between year 2005 and 2008. Age group of 60 years or older, diabetes, cardiac disorders, asthma, and having two or more pre-existing comorbidities were independent risk factors of severe organ involvement. Abdominal pain, clinical fluid accumulation, and hematocrit rise and rapid platelet count drop at presentation were significantly associated with severe organ involvement. These risk factors, when validated in a larger study, will be useful for triage by clinicians for prompt monitoring and clinical management at first presentation, to minimize the risk of severe organ involvement and hence, disease severity.

    The occupational asthma is the most common form of lung disease caused by factors that are attributed to a specific working environment in industrialized countries. It causes variable limitation of airflow and/or hyper-responsiveness of the airway due to contact with specific agents present in an atmosphere of work and not to stimuli found out of this place. It is recognized more and more frequently, and many agents are capable of causing occupational asthma by different pathophysiological mechanisms. More than 400 agents causing occupational asthma are known and every year new triggers are detected. Numerous factors contribute to the pathogenesis of occupational asthma induced chemically, including immunological, non-immunological mechanisms of epithelial damage, airway remodeling, oxidative stress, neurogenic inflammation as well as genetic factors. The most important risk factors for occupational asthma include: atopy, smoking and genetic factors. The diagnosis is based on the clinical history, skin tests, immunological tests and functional studies. The fundamental treatment is removing the worker from exposure as soon as possible. The advance in the knowledge of the pathogenesis of occupational asthma will importantly influence in the prevention and the management of this disease.

    2012-01-01

    Background Advances in medical science have enabled many children with chronic diseases to survive to adulthood. The transition of adult patients with childhood-onset chronic diseases from pediatric to adult healthcare systems has received attention in Europe and the United States. We conducted a questionnaire survey among 41 pediatricians at pediatric hospitals and 24 nurses specializing in adolescent care to compare the perception of transition of care from pediatric to adult healthcare services for such patients. Findings Three-fourths of the pediatricians and all of the nurses reported that transition programs were necessary. A higher proportion of the nurses realized the necessity of transition and had already developed such programs. Both pediatricians and nurses reported that a network covering the transition from pediatric to adult healthcare services has not been established to date. Conclusions It has been suggested that spreading the importance of a transition program among pediatricians and developing a pediatric-adult healthcare network would contribute to the biopsychosocial well-being of adult patients with childhood-onset chronic disease.

  20. Psychiatric factors in asthma: implications for diagnosis and therapy.

    2003-01-01

    Emotional factors are an obstacle in the diagnosis and management of asthma. This review discusses three problem patterns: negative emotions in relatively normal patients with asthma; patients presenting possible functional symptoms and; patients presenting asthma in conjunction with psychiatric deviations. Negative emotions influence the symptoms and management of asthma, even in relatively normal patients. Psychogenic symptoms appear normal, but culminate in functional symptoms in a minority of patients. Diagnosing and treating asthma in patients with comorbid asthma and psychiatric symptoms is very difficult. On the one hand, treating asthma may often be just treating the emotions. On the other hand, negative emotions make the treatment of asthma guesswork. Physicians should estimate emotional influences in their patients' symptoms for an optimal evaluation of medication efficacy. Assessment and analysis of emotional factors surrounding exacerbations seems essential, e.g. emotional precipitants of asthma and asthma-evoked negative emotions. Moreover, patients should be informed about stress-induced breathlessness and the consequences of overuse of bronchodilators. When patients present with atypical symptoms, or do not properly respond to asthma medication, functional symptoms should be suspected. Psychiatric analysis may often lead to the conclusion that symptoms have a functional basis. In patients with comorbid asthma and anxiety disorders, asthma should be the focus for treatment since difficult-to-control asthma often causes anxiety problems in the first place. Moreover, panic-like symptoms in asthma are often related to sudden onset asthma exacerbations. However, in patients with comorbid asthma and depression, depression should become the focus of treatment. The reason is that optimal treatment of depressive asthmatics is probably impossible. Special issues include specific problems with children, compliance problems, and physicians' dilemmas regarding

    A recent systematic review and meta-analysis has shown the effect of indoor mildew odour on allergic rhinitis risk, but its relation to other common chronic health outcomes in adults has not been investigated. Therefore, it was aimed to examine the relationship of indoor mildew odour and common health outcomes in adults in a national and population-based setting. Data was retrieved from the United States National Health and Nutrition Examination Surveys, 2005-2006, including the available information on demographics, housing characteristics, self-reported health conditions and urinary concentrations of environmental chemicals. T test, chi-squared test and survey-weighted logistic regression modelling were performed. Of all American adults (n = 4979), 744 (15.1%) reported indoor mildew odour or musty smell in their households. People who reported indoor mildew odour or musty smell also reported poorer self-rated health, sleep complaints, chronic bronchitis, asthma attack, itchy rash, sneezing and poor vision. In addition, people who reported indoor mildew odour or musty smell also tended to reside in older housing that were built 20 years earlier. However, there were no significant statistical associations found between indoor mildew odour or musty smell and urinary concentrations of environmental chemicals, which was also found to be associated with old housing. People who lived in older housing with indoor mildew odour or musty smell tended to have chronic health problems. To protect occupants in old housing from chronic illnesses associated with indoor mildew odour, elimination of the odour sources should be explored in future research and therefore public health and housing programs.

  2. Management of severe asthma in children.

    Children who are referred to specialist care with asthma that does not respond to treatment (problematic severe asthma) are a heterogeneous group, with substantial morbidity. The evidence base for management is sparse, and is mostly based on data from studies in children with mild and moderate asthma and on extrapolation of data from studies in adults with severe asthma. In many children with severe asthma, the diagnosis is wrong or adherence to treatment is poor. The first step is a detailed diagnostic assessment to exclude an alternative diagnosis ("not asthma at all"), followed by a multidisciplinary approach to exclude comorbidities ("asthma plus") and to assess whether the child has difficult asthma (improves when the basic management needs, such as adherence and inhaler technique, are corrected) or true, therapy-resistant asthma (still symptomatic even when the basic management needs are resolved). In particular, environmental causes of secondary steroid resistance should be identified. An individualised treatment plan should be devised depending on the clinical and pathophysiological characterisation. Licensed therapeutic approaches include high-dose inhaled steroids, the Symbicort maintenance and reliever (SMART) regimen (with budesonide and formoterol fumarate), and anti-IgE therapy. Unlicensed treatments include methotrexate, azathioprine, ciclosporin, and subcutaneous terbutaline infusions. Paediatric data are needed on cytokine-specific monoclonal antibody therapies and bronchial thermoplasty. However, despite the interest in innovative approaches, getting the basics right in children with apparently severe asthma will remain the foundation of management for the foreseeable future.

    We examined associations between types of childhood maltreatment and the onset, escalation, and severity of substance use in cocaine dependent adults. In men (n = 55), emotional abuse was associated with a younger age of first alcohol use and a greater severity of substance abuse. In women (n = 32), sexual abuse, emotional abuse, and overall maltreatment was associated with a younger age of first alcohol use, and emotional abuse, emotional neglect, and overall maltreatment was associated with a greater severity of substance abuse. There was no association between childhood maltreatment and age of nicotine or cocaine use. However, age of first alcohol use predicted age of first cocaine use in both genders. All associations were stronger in women. Findings suggest that early intervention for childhood victims, especially females, may delay or prevent the early onset of alcohol use and reduce the risk for a more severe course of addiction.

    We report a new family with autosomal dominant inheritance of a late onset rapidly progressive leukodystrophy in which exome sequencing has revealed a novel mutation p.R782G in the Colony-Stimulating Factor 1 Receptor gene (CSF1R). Neuropathology of two affected family members showed cerebral white matter degeneration with axonal swellings and pigmented macrophages. The few recently reported families with CSF1R mutations had been previously labelled “hereditary diffuse leukencephalopathy with axonal spheroids” (HDLS) and “pigmentary orthochromatic leukodystrophy” (POLD), disorders which now appear to form a disease continuum. The term “adult-onset leukoencephalopathy with axonal spheroids and pigmented glia” (ALSP) has been proposed to encompass this spectrum. As CSF1R regulates microglia this mutation implies that dysregulation of microglia is the primary cause of the disease. PMID:25975230

    Background Personally controlled health management systems (PCHMS), which may include a personal health record (PHR), health management tools, and information resources, have been advocated as a next-generation technology to improve health behaviors and outcomes. There have been successful trials of PCHMS in various health settings. However, there is mixed evidence for whether consumers will use these systems over the long term and whether they ultimately lead to improved health outcomes and behaviors. Objective The aim was to test whether use of a PCHMS by consumers can increase the uptake or updating of a written asthma action plan (AAP) among adults with asthma. Methods A 12-month parallel 2-group randomized controlled trial was conducted. Participants living with asthma were recruited nationally in Australia between April and August 2013, and randomized 1:1 to either the PCHMS group or control group (online static educational content). The primary outcome measure was possession of an up-to-date written AAP poststudy. Secondary measures included (1) utilizing the AAP; (2) planned or unplanned visits to a health care professional for asthma-related concerns; (3) severe asthma exacerbation, inadequately controlled asthma, or worsening of asthma that required a change in treatment; and (4) number of days lost from work or study due to asthma. Ancillary analyses examined reasons for adoption or nonadoption of the intervention. Outcome measures were collected by online questionnaire prestudy, monthly, and poststudy. Results A total of 330 eligible participants were randomized into 1 of 2 arms (intervention: n=154; control: n=176). Access to the PCHMS was not associated with a significant difference in any of the primary or secondary outcomes. Most participants (80.5%, 124/154) did not access the intervention or accessed it only once. Conclusions Despite the intervention being effective in other preventive care settings, system use was negligible and outcome changes

    Occupational asthma is probably much more common than is generally realized. Though many causes have been described, undoubtedly many more are yet to be recognized. One of the diagnostic difficulties lies in the fact that in most forms of this disease a late asthmatic reaction occurs in the evening rather than at work. The pathogenetic mechanisms differ in various forms of occupational asthma. In some, an immunologic mechanism is likely; in others, a "pharmacologic" action of the offending agent is implicated. Asthma due to inhalation of dusts of western red cedar, isocyanates, detergent enzymes and textiles is considered in detail. Periodic examination of workers at risk is of value for early diagnosis and prevention of irrversible airway obstruction. PMID:766943

    Extensive epidemiologic research from the United States demonstrates that childhood adversities (CAs) are predictive of several psychiatric outcomes, including depression, anxiety, substance abuse, and externalizing disorders. To date, this has not been explored in a national sample of adults in South Africa. The present study examined the joint predictive effects of 11 retrospectively reported CAs on the first onset of DSM-IV disorders in the South Africa Stress and Health Study (SASH), a nationally representative sample of adults. We utilized substantively plausible regression models of joint CA effects that account for the comorbidity between individual CAs; outcomes included DSM-IV anxiety disorders, mood disorders, substance use disorders, and externalizing disorders measured with the WHO Composite International Diagnostic Interview. The results indicated that experiences of CA varied by race, and many CAs were correlated with one another. The best-fitting model for first onset of any disorder included separate indicators for each type of CA, in addition to indicator variables for the number of other CAs reported. Results disaggregated by class of disorder showed that the majority of CAs with significant odds ratios only predicted anxiety disorder. Results disaggregated by life course stage of first onset showed that significant effects of CAs can be observed at each stage of the life course. This study contributes to a growing body of research on the social determinants of mental health in South Africa. Our findings illustrate the importance of utilizing a model that accounts for the clustering and accumulation of CAs, and suggest that a variety of CAs predict onset of mental disorders, particularly anxiety disorders, at several stages of the life course.

    There is ample data suggesting that individuals with bipolar disorder more frequently suffer from disturbed sleep even when euthymic. Since sleep is a process that is crucial for affective homeostasis, disturbed sleep in healthy individuals may be a risk factor for the subsequent onset of bipolar disorder. Utilizing data from a large cohort of adolescents and young adults, this study tests the hypothesis that disturbed sleep constitutes a risk factor for the later onset of bipolar disorder. A representative community sample of N = 3021 adolescents and young adults (baseline age 14-24) was assessed using the standardized Composite International Diagnostic Interview and followed-up prospectively up to 3 times over up to 10 years. Disturbed sleep at baseline was quantified utilizing the corresponding items from the self-report inventory SCL-90-R. The compound value (insomnia-score) as an ordinal parameter for the severity of sleep disturbances was used to assess associations with the incidence of bipolar disorder among participants free of major mental disorder at baseline (N = 1943) using odds ratios (OR) from logistic regressions. Analyses were adjusted for age, gender, parental mood disorder and lifetime alcohol or cannabis dependence. Poor sleep quality significantly increased the risk for the subsequent development of bipolar disorder (OR = 1.75; p = 0.001). Regarding individual sleep items, trouble falling asleep and early morning awakening were predictive for the subsequent onset of bipolar disorder. Disturbed sleep in persons otherwise free of major mental disorders appears to confer an increased risk for the subsequent onset of bipolar disorder.

    Fas is an apoptosis-related cell surface molecule whose defective transcription results in the lpr defect and autoimmunity. Recent analysis of Fas mRNA and protein expression in normal mice showed high expression in the thymus, on activated T cells, and on 5-10% of peripheral T cells. To investigate the role of Fas in the thymus, we analyzed its expression in fetal and adult thymocyte subsets. Fas was not expressed on fetal nor adult CD8-CD4- (double-negative, DN) T cell precursors. The earliest precursors that expressed low levels of FAS were the immediate precursors of DP thymocytes that bear the CD44-CD25-CD8loCD4loTCRlo phenotype. Other DN cells that expressed Fas appeared to be either non-T cells or mature alpha beta + DN thymocytes. The onset of Fas expression followed the onset of expression of CD8 and CD4 and Fas expression reached its peak in CD8+CD4+ double-positive (DP) thymocytes. Both single-positive (SP) subsets were largely Fas+ (CD8 SP < CD4 SP) but expressed lower levels of Fas than DP cells. However, a majority (> 60%) of the most mature HSA(lo) SP cells (2-5% of all SP thymocytes) were Fas- and the remainder of the HSA(lo) SP cells was Fas(lo). We observed two main differences between Fas expression on fetal versus adult thymocytes. First, up to 90% of fetal gamma delta + DN cells expressed high levels of Fas, in contrast to the very low expression (< 7% Fas+ cells) among adult gamma delta + thymocytes. Second, whereas virtually all adult DP cells were Fas+, up to 75% of fetal day 16 DP cells were Fas-.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background Consensus statements recommend the addition of long-acting inhaled ß2-agonists (LABA) only in asthmatic patients who are inadequately controlled on inhaled corticosteroids (ICS). It is not uncommon for some patients to be commenced on ICS and LABA together as initial therapy. Objectives To compare the efficacy of combining inhaled corticosteroids with long-acting ß2-agonists (ICS+LABA) with inhaled corticosteroids alone (ICS alone) in steroid-naive children and adults with persistent asthma. We assessed two protocols: (1) LABA + ICS versus a similar dose of ICS (comparison 1) and (2) LABA + ICS versus a higher dose of ICS (comparison 2). Search methods We identified randomised controlled trials through electronic database searches (May 2008). Selection criteria Randomised trials comparing ICS + LABA with ICS alone in children and adults with asthma who had no inhaled corticosteroids in the preceding 28 days prior to enrolment. Data collection and analysis Each author assessed studies independently for risk of bias and extracted data. We obtained confirmation from the trialists when possible. The primary endpoint was rate of patients with one or more asthma exacerbations requiring rescue systemic corticosteroids. Results are expressed as relative risks (RR) for dichotomous data and as mean differences (MD) or standardised mean differences (SMD) for continuous data. Main results Twenty-eight study comparisons drawn from 27 trials (22 adult; five paediatric) met the review entry criteria (8050 participants). Baseline data from the studies indicated that trial populations had moderate or mild airway obstruction (FEV1 65% predicted), and that they were symptomatic prior to randomisation. In comparison 1, the combination of ICS and LABA was not associated with a significantly lower risk of patients with exacerbations requiring oral corticosteroids (RR 1.04; 95% confidence interval (CI) 0.73 to 1.47) or requiring hospital admissions (RR 0.38; 95% CI 0.09 to 1

    Adult onset Still's disease (AOSD) is an uncommon, multisystemic, auto-inflammatory disorder, while breast augmentation is a very common cosmetic procedure. We describe a case in which these two coalesce, AOSD, manifested with pleuritis and pericarditis, developed after breast mammoplasty. The pathogenetic, missing link, behind the development of AOSD following mammoplasty, is thought to be the autoimmune (auto-inflammatory) syndrome induced by adjuvants (ASIA). We reviewed other cases of AOSD associated with breast mammoplasty published to date and the literature regarding AOSD and ASIA syndrome. The review is followed by a short debate of whether silicone implants should be explanted in similar, future cases.

    Background An integrated breathing and relaxation technique known as the Papworth method has been implemented by physiotherapists since the 1960s for patients with asthma and dysfunctional breathing, but no controlled trials have been reported. This study evaluated the effectiveness of the Papworth method in a randomised controlled trial. Methods Eighty‐five patients (36 men) were individually randomised to the control group (n = 46) or to the intervention group receiving five sessions of treatment by the Papworth method (n = 39). Both groups received usual medical care. Assessments were undertaken at baseline, post‐treatment (6 months after baseline) and at 12 months. The primary outcome measure was the St George's Respiratory Symptoms Questionnaire (SGRQ). Secondary outcome measures included the Hospital Anxiety and Depression Scale (HADS), the Nijmegen dysfunctional breathing questionnaire and objective measures of respiratory function. Results Post‐treatment and 12 month data were available for 78 and 72 patients, respectively. At the post‐treatment assessment the mean (SD) score on the SGRQ Symptom subscale was 21.8 (18.1) in the intervention group and 32.8 (20.1) in the control group (p = 0.001 for the difference). At the 12 month follow‐up the corresponding figures were 24.9 (17.9) and 33.5 (15.9) (p = 0.007 for the difference). SGRQ Total scores and HADS and Nijmegen scores were similarly significantly lower in the intervention group than in the control group. The groups did not differ significantly following the treatment on objective measures of respiratory function except for relaxed breathing rate. Conclusions The Papworth method appears to ameliorate respiratory symptoms, dysfunctional breathing and adverse mood compared with usual care. Further controlled trials are warranted to confirm this finding, assess the effect in other patient groups and determine whether there is some effect on objective measures of

    Four series of experiments involving 44 animals were carried out to investigate the influence of transportation, proximity of sexually mature adults and other stimuli on the onset of puberty in the gilt. Transportation per se, either real or simulated, did not induce early puberty in the gilt. In contrast, the most effective stimulus was provided by accommodating the gilts in pens adjacent to mature breeding stock. Gilts housed in a sow yard exhibited oestrus when aged between 153 and 184 days, i.e. 4-6 weeks after the beginning of the experiment. This compares with 189 to 227 days, i.e. 9-12 weeks after the start of the experiment for those gilts not housed adjacent to adult stock.

    Acyl-CoA:monoacylglycerol acyltransferase (MGAT) 2 catalyzes triacylglycerol (TAG) synthesis, required in intestinal fat absorption. We previously demonstrated that mice without a functional MGAT2-coding gene (Mogat2−/−) exhibit increased energy expenditure and resistance to obesity induced by excess calories. One critical question raised is whether lacking MGAT2 during early development is required for the metabolic phenotypes in adult mice. In this study, we found that Mogat2−/− pups grew slower than wild-type littermates during the suckling period. To determine whether inactivating MGAT2 in adult mice is sufficient to confer resistance to diet-induced obesity, we generated mice with an inducible Mogat2-inactivating mutation. Mice with adult-onset MGAT2 deficiency (Mogat2AKO) exhibited a transient decrease in food intake like Mogat2−/− mice when fed a high-fat diet and a moderate increase in energy expenditure after acclimatization. They gained less weight than littermate controls, but the difference was smaller than that between wild-type and Mogat2−/− mice. The moderate reduction in weight gain was associated with reduced hepatic TAG and improved glucose tolerance. Similar protective effects were also observed in mice that had gained weight on a high-fat diet before inactivating MGAT2. These findings suggest that adult-onset MGAT2 deficiency mitigates metabolic disorders induced by high-fat feeding and that MGAT2 modulates early postnatal nutrition and may program metabolism later in life.

  18. Vitamin D and asthma-life after VIDA?

    The vitamin D hypothesis postulates that lower vitamin D levels are causally associated with increased asthma risk and asthma severity. Multiple epidemiological studies have shown an inverse relationship between circulating vitamin D levels (in the form of 25-hydroxy vitamin D) and asthma severity and control and lung function. However, in the recently published vitamin D and asthma (VIDA) study, vitamin D supplementation failed to show an improvement in asthma control in adults. This article reviews the current epidemiological and trial evidence for vitamin D and asthma and explores some of the possible alternative explanations for previous findings (including "reverse causation" and the importance of studying children and adults). We also address some of the unique challenges of conducting vitamin D trials and potential ways to address them. Finally, I will argue for further clinical trials of vitamin D in asthma, especially in children, using knowledge gained from the VIDA trial.
