    The association between ADHD and allergy remains controversial. Our previous findings suggest that nerve growth factor may link the nervous and immune systems. The primary objective of this study was to determine if a combination of cetirizine + methylphenidate is effective in children with comorbid ADHD and allergic rhinitis. We also examined the role of nerve growth factor in these comorbidities. Our randomized, double-blind, placebo-controlled, crossover study enrolled 38 children diagnosed with comorbid ADHD and allergy using cetirizine (n = 12), sustained-release methylphenidate (n = 12), or cetirizine + methylphenidate (n = 14). Endpoints compared baseline to posttreatment evaluations for allergic rhinitis and ADHD scores. Serum nerve growth factor levels were measured using ELISA. For allergy endpoints, combination therapy produced results superior to individual therapy. For ADHD, similar scores were achieved for individual therapy; however, combination therapy resulted in improved scores. Nerve growth factor levels were downregulated following this trend. We conclude that ADHD and allergic rhinitis may have common mechanism and represent a comorbid condition that links the nervous system to the immune system. Further studies are needed. PMID:27872863

    Allergic diseases such as asthma and rhinitis, as well the early phase of atopic dermatitis, are characterized by a Th2-skewed immune environment. Th2-type cytokines are upregulated in allergic inflammation, whereas there is downregulation of the Th1-type immune response and related cytokines, such as interferon-x03B3; (IFN-x03B3;). The latter is a strong inducer of indoleamine 2,3-dioxygenase-1 (IDO-1), which degrades the essential amino acid tryptophan, as part of an antiproliferative strategy of immunocompetent cells to halt the growth of infected and malignant cells, and also of T cells - an immunoregulatory intervention to avoid overactivation of the immune system. Raised serum tryptophan concentrations have been reported in patients with pollen allergy compared to healthy blood donors. Moreover, higher baseline tryptophan concentrations have been associated with a poor response to specific immunotherapy. It has been shown that the increase in tryptophan concentrations in patients with pollen allergy only exists outside the pollen season, and not during the season. Interestingly, there is only a minor alteration of the kynurenine to tryptophan ratio (Kyn/Trp, an index of tryptophan breakdown). The reason for the higher tryptophan concentrations in patients with pollen allergy outside the season remains a matter of discussion. To this regard, the specific interaction of nitric oxide (NO∙) with the tryptophan-degrading enzyme IDO-1 could be important, because an enhanced formation of NO∙ has been reported in patients with asthma and allergic rhinitis. Importantly, NO∙ suppresses the activity of the heme enzyme IDO-1, which could explain the higher tryptophan levels. Thus, inhibitors of inducible NO∙ synthase should be reconsidered as candidates for antiallergic therapy out of season that may abrogate the arrest of IDO-1 by decreasing the production of NO∙. Considering its association with the pathophysiology of atopic disease, tryptophan metabolism may

    Allergic asthma refers to a chronic reversible bronchoconstriction influenced by an allergic trigger, leading to symptoms of cough, wheezing, shortness of breath, and chest tightness. Allergic bronchopulmonary aspergillosis is a complex hypersensitivity reaction, often in patients with asthma or cystic fibrosis, occurring when bronchi become colonized by Aspergillus species. The clinical picture is dominated by asthma complicated by recurrent episodes of bronchial obstruction, fever, malaise, mucus production, and peripheral blood eosinophilia. Hypersensitivity pneumonitis is a syndrome associated with lung inflammation from the inhalation of airborne antigens, such as molds and dust. Copyright © 2016 Elsevier Inc. All rights reserved.

  4. Prevention of allergic disorders.

    Allergic disease produces substantial pediatric morbidity and individual dysfunction, making its mechanisms an appropriate target for clarification and preventive strategies. Disease expression seems to reflect a constellation of determinants that controls IgE production variably, affects specific function of target organs, and determines exposure to putative allergens. Bases for the two former factors are being defined rapidly and appear to be controlled genetically. Therefore, although stronger eugenic motivation will be required to exploit even present information for effective prevention, parental phenotypes can provide a rough indication of postconceptive risk. Despite many divergent data, current evidence fails to support the value of gestational strategies undertaken to prevent allergic disease in the newborn; however, this risk apparently may be reduced by avoiding postnatal allergens. The protection afforded seems to be allergen-specific rather than somehow serving to abate "the allergic tendency." Evidence increasingly is persuasive that sensitization to pollens, foods, and possibly other agents is prone to occur in the first 6 to 12 months of life. Strategies that exclude potent food allergens from the diets of high-risk infants appear to reduce the occurrence of atopic dermatitis, but seem far less able to influence respiratory symptoms. Efforts to limit exposure to potent inhalant allergens (eg, dust mites, animal "danders") are now also feasible and offer quite effective secondary and, perhaps, primary prevention. Trials of these strategies and clarification of other domestic contaminant effects on child health offer "homely" but valid and potentially useful approaches to reducing the impact of allergic disease.

  5. Role of Galectins in Allergic Disorders.

    2016-01-01

    Allergen avoidance, pharmacotherapy; with antihistamines, anti-leukotrienes, corticosteroids and bronchodilators.as well as monoclonal antibodies; and allergen specific immunotherapy stand as confirmed approaches for the management of allergic disorders as asthma, allergic rhinitis/rhinoconjunctivitis, atopic dermatitis, food allergies and anaphylaxis. Galectins are members of animal lectin protein family, with binding specificity for β-galactoside sugars. These highly conserved proteins are known to be expressed in various effector cells of the immune system, exert immuno-regulatory activities, and enroll in tissue inflammation and regulation of immune homeostasis. This review aims to explain the galectin family and influence of galectins in the immune mechanisms of allergic disorders. Galectins have multiple roles in innate and adaptive immunity. Intense research in the field of immunology related with galectins have given rise to several patent applications. Those, increasing in vivo efficacy of galectins for therapeutic applications, utilizing galectins for immune stimulation and prolongation of immune responses, utilization of them as disease markers are pioneers. As immune cells can be targeted by galectins, cells containing these molecules can be used for immune intervention. Regulation of cytokine productions by immune cells as IL-1β and IL-10 as well as dendritic cell functions by galectins may be efficient in limitation of some immune-mediated disorders. Taken all together, better learning of galectin biology together with detailed revealing of galectin-immune system interactions have great potential for immune interventions targeting allergy-related disorders.

  6. [The psychoimmunological network og panic disorders, agoraphobia and allergic reactions].

    1995-02-01

    While treating panic and agoraphobia patients with behaviour therapy, a high frequency of allergic reaction of the IgE-mediated type I was observed. Panic disorder, agoraphobia, allergic disorder, and vasomotor reactions are briefly discussed in the framework of psycho-endocrino-immunological research. A pilot study had shown a high correlation between panic disorder with and without agoraphobia and allergic reaction. A controlled study was then planned to test the hypothesized psychoimmunological relationship. 100 allergic patients, 79 panic/agoraphobic patients, and 66 controls underwent psychodiagnostic and allergic screening. 70% of the anxiety patients responded to test allergens with IgE-mediated type-I immediate reactions in comparison to 28% of the control persons. Another 15% of the panic patients reacted to nickle compound with type-IV delayed skin reactions (7% of the controls). Conversely, 10% of the allergic patients suffered from panic disorder (45% had experienced panic attacks) in contrast to 2% of the controls (24% of these reported panic attacks). The relative risk for allergic patients to develop panic disorder with and without agoraphobia is obviously five times as high as for controls. With this assumption of a psychoimmunological preparedness in mind, a behavioural medical diagnostic and therapeutic concept seems more adequate in coping both with panic/agoraphobia and allergic disorder.

    Context Allergy symptoms that affect the eyes are common in adults and children worldwide, and are often associated with nasal allergy symptoms, prompting the term ‘rhinoconjunctivitis’ to describe the condition. However, this condition has not always been recognized, and earlier literature reported allergic conjunctivitis only within a subset of nasal allergy patients. Evidence Acquisition To assess the current state of ocular allergy epidemiology, pathophysiology, and currently available treatment options, we performed a MEDLINE search for articles regarding ocular allergy, rhinoconjunctivitis, vernal keratoconjunctivitis (VKC), atopic keratoconjunctivitis (AKC), and giant papillary conjunctivitis (GPC). Evidence Synthesis The more severe forms of ocular allergy are not only distressing, but can also threaten a patient's vision. Each type of ocular allergy is associated with ocular redness, itching, and tearing; however, AKC and VKC can threaten the cornea, and research has revealed that involvement of different immune cell populations (mast cells, eosinophils, and lymphocytes) may cause these more severe symptoms. A variety of treatment options exist to control ocular allergy symptoms. Nonpharmacologic options include allergen avoidance and lubrication with saline, and if these fail to be sufficiently effective, symptom relief may be provided by medicinal agents that are either applied topically to the eye or taken orally. Recent evidence suggests that nasal allergy treatments applied topically to the nose may also positively affect ocular allergy symptoms, which raises the interesting possibility that a parasympathetic nasal-ocular neural reflex pathway may be involved in the stimulation of allergic responses in the eye. Conclusions Ocular allergy is underdiagnosed and has a significant impact on the life of the patient. It is vital to reach a better understanding of ocular allergic mechanisms and inflammation, which may lead to improved treatment. PMID

  8. Dehydroepiandrosterone, dehydroepiandrosterone sulfate and related steroids: their role in inflammatory, allergic and immunological disorders.

    PubMed

    Dillon, Joseph S

    2005-06-01

    Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are metabolic intermediates in the production of potent androgens, estrogens and other less well-characterized steroids. DHEA(S) and closely related steroid hormones have a variety of immunological effects both in vitro and in vivo in experimental animals and humans. Many of these effects have been demonstrated in animal models where there is little circulating DHEA(S), and the demonstrated effects are generally seen at concentrations of DHEA(S) which are supra-physiological in man. The physiological role of DHEA(S) in the immunological system is unknown. Furthermore, the molecular mechanism of action of DHEA(S) is unclear. In this review, I focus on studies of the immunological effects of DHEA(S) and closely related steroid metabolites and analogs, mainly derived from literature published in the last five years. My purpose is to describe the demonstrated effects and to highlight some of the remaining major research issues in this field. These issues include defining the molecular mechanism of DHEA(S) action; determining whether the effect of DHEA(S) is related to the steroid itself or to a metabolic product of DHEA; determining the relationship of physiological function to the pharmacological effects; and determining the molecular basis for species-specific differences in effects.

    Oral bepotastine is a second-generation histamine H(1) receptor antagonist that also suppresses some allergic inflammatory processes. Numerous short- and long-term clinical trials and surveillance studies have shown that twice-daily bepotastine is an effective and generally well tolerated antihistamine in the treatment of patients with allergic rhinitis, chronic urticaria or pruritus associated with skin conditions (eczema/dermatitis, prurigo or pruritus cutaneus). Bepotastine 20 mg/day was significantly more effective than terfenadine 120 mg/day in patients with perennial allergic rhinitis, as evaluated by the final global improvement rating and several other endpoints in a phase III trial. In phase III trials in patients with chronic urticaria, bepotastine 20 mg/day was more effective than placebo in improving levels of itching and eruption, and as effective as terfenadine 120 mg/day with regard to the final global improvement rating and other endpoints. In a noncomparative trial in patients with pruritus associated with skin diseases, the majority of bepotastine recipients in the overall population, as well as in the specific skin disease subgroups (eczema/dermatitis, prurigo or pruritus cutaneus), had a final global improvement rating of moderate or greater. Bepotastine was generally well tolerated in adult and paediatric patients with allergic conditions.

    To review the results from recent studies that assessed the burden of allergic diseases on the patients' every-day life, or contributed to new advances in monitoring quality-of-life in allergic disorders. This review will not report the numerous clinical trials that included quality-of-life as an outcome. Quality-of-life impairment was investigated in patients with asthma, allergic rhinitis, atopic dermatitis or food allergy. A new questionnaire was validated for patients with yellow jacket allergy. At the same time, the properties of formerly developed questionnaires were further investigated and tools were developed to assess factors related to quality-of-life, such as work functioning, or perceived control of the disease. Allergic disorders are associated with a variety of limitations in the patients' daily life. The relative burden of concomitant disorders, however, has not been thoroughly investigated. When monitoring quality-of-life, investigators should ensure that the results are not biased by confounding factors that may affect quality-of-life. Moreover, the uncertainty around estimates of change in health status related to treatment and around standard thresholds for clinical significance should be taken into account before drawing inference as regards the treatment worthiness.

    The worldwide prevalence of allergic diseases such as rhinitis, asthma, and atopic dermatitis is continuously increasing, while other allergic disorders such as urticaria and angioedema are less investigated. We performed a population study evaluating the prevalence of any kind of allergic disorders. The entire population of 7,201 inhabitants of Cotignola (Ravenna, Italy) was surveyed by a questionnaire assessing symptoms related to rhinitis, asthma, anaphylaxis, skin symptoms and insect sting allergy as well as the features of clinical presentations, diagnosis, and treatment received. Valid questionnaires were obtained by 6,676 inhabitants (92.7%). The sample was formed by 3,266 males and 3,495 females, the mean age was 45.6 years; 1,035 subjects (15.5%) were aged less than 18 years; 404 subjects (6%) had at least one episode of wheezing/breathlessness in their lifetime, and 243 of them (60.1%) had a diagnosis of asthma; 1,002 subjects (14.8%) had nose symptoms in their lifetime, and 375 of them (37.4%) had a diagnosis of allergic rhinitis or rhinoconjunctivitis. For other allergic manifestations, data were obtained from 5,730 subjects; of them, 178 (3.1%) had skin symptoms, 59 (1.1%) had oral symptoms, and 37 (0.6%) had anaphylaxis; 207 (3.6%) had reactions to insect stings. There were no significant differences in prevalence between Italians and immigrants. Only 51.7% of subjects with asthma, 46.5% of those with rhinitis, 22.7% of those with other allergies, but 97.1% of those with insect allergy, received treatment. These findings confirm recent data on epidemiology of allergic diseases in Europe, particularly in Italy, and add some details on how such diseases are managed.

    The prevalence of allergic airway diseases such as asthma and rhinitis has increased dramatically to epidemic proportions worldwide. Besides air pollution from industry derived emissions and motor vehicles, the rising trend can only be explained by gross changes in the environments where we live. The world economy has been transformed over the last 25 years with developing countries being at the core of these changes. Around the planet, in both developed and developing countries, environments are undergoing profound changes. Many of these changes are considered to have negative effects on respiratory health and to enhance the frequency and severity of respiratory diseases such as asthma in the general population. Increased concentrations of greenhouse gases, and especially carbon dioxide (CO2), in the atmosphere have already warmed the planet substantially, causing more severe and prolonged heat waves, variability in temperature, increased air pollution, forest fires, droughts, and floods - all of which can put the respiratory health of the public at risk. These changes in climate and air quality have a measurable impact not only on the morbidity but also the mortality of patients with asthma and other respiratory diseases. The massive increase in emissions of air pollutants due to economic and industrial growth in the last century has made air quality an environmental problem of the first order in a large number of regions of the world. A body of evidence suggests that major changes to our world are occurring and involve the atmosphere and its associated climate. These changes, including global warming induced by human activity, have an impact on the biosphere, biodiversity, and the human environment. Mitigating this huge health impact and reversing the effects of these changes are major challenges. This statement of the World Allergy Organization (WAO) raises the importance of this health hazard and highlights the facts on climate-related health impacts

  13. Actual therapeutic management of allergic and hyperreactive nasal disorders

    PubMed Central

    Rudack, Claudia

    2004-01-01

    Allergic rhinitis (AR) and hyperractive disorders of the upper airways, depending upon the type of releasing stimuli, are defined as nasal hyperreactivity, for example in the case of AR, or as non-specific nasal hyperreactivity and as idiopathic rhinitis (IR) (synonyms frequently used in the past: non-specific nasal hyperreactivity; vasomotor rhinitis) in the case of non-characterised stimuli. An early and professional therapy of allergic disorders of the upper airways is of immense importance as allergic rhinitis is detected in comorbidities such as asthma and rhino sinusitis. The therapeutic concept is influenced by new and further developments in pharmacological substance classes such as antihistamines and glucocorticosteroids. Specific immune therapy, the only causal therapy for AR, has been reviewed over the past few years in respect of the type and pattern of application. However, to date no firm recommendations on oral, sublingual and /or nasal immune therapy have yet been drawn up based on investigations of these modifications. Therapeutic management of IR is aimed at a symptom-oriented therapy of nasal hyperactivity as etiological factors relating to this form of rhinitis are not yet sufficiently known. Drug groups such as mast cell stabilizers, systemic and topic antihistamines, topic and systemic glucocorticosteroids, ipatroium bromide and alpha symphatomimetics belong to the spectrum of the therapeutics employed.

Systematic review and meta-analysis. Medline, Embase, ISI Science Citation Index, BIOSIS, ISI Web of Knowledge, UK National Research Register, clinical trials.gov, the Index to Theses and Digital dissertations, and grey literature using OpenSIGLE. Genetic epidemiological studies (family, case-control) of the association between filaggrin gene defects and allergic sensitisation or allergic disorders. Atopic eczema or dermatitis, food allergy, asthma, allergic rhinitis, and anaphylaxis, along with relevant immunological variables relating to the risk of allergic sensitisation as assessed by either positive skin prick testing or increased levels of allergen specific IgE. 24 studies were included. The odds of developing allergic sensitisation was 1.91 (95% confidence interval 1.44 to 2.54) in the family studies and 1.57 (1.20 to 2.07) in the case-control studies. The odds of developing atopic eczema was 1.99 (1.72 to 2.31) in the family studies and 4.78 (3.31 to 6.92) in the case-control studies. Three studies investigated the association between filaggrin gene mutations and allergic rhinitis in people without atopic eczema: overall odds ratio 1.78 (1.16 to 2.73). The four studies that investigated the association between filaggrin gene mutations and allergic rhinitis in people with atopic eczema reported a significant association: pooled odds ratio from case-control studies 2.84 (2.08 to 3.88). An overall odds ratio for the association between filaggrin gene mutations and asthma in people with atopic eczema was 2.79 (1.77 to 4.41) in case-control studies and 2.30 (1.66 to 3.18) in family studies.

    Several studies have shown that indoor pollution increases the risk for chronic pulmonary diseases and acute respiratory symptoms in children/adolescents. Some associations have been confirmed by studies. Other relations are still unclear, such as those regarding dog and cat ownership. In this study we assessed the relationships of the exposure to mould and dog/cat ownership with respiratory/allergic symptoms/diagnoses, such as wheezing, asthma, rhinoconjunctivitis, eczema, and cough/phlegm in 20,016 children (6-7 yrs old) and 13,266 adolescents (13-14 yrs old) from 12 Italian areas. Early mould exposure (in the first year of life) was positively related to all considered symptoms/diagnoses (significantly for wheezing, asthma, rhinoconjunctivitis in both children and adolescents, and for cough/phlegm among children); current exposure (in the last year) was a significant risk factor for wheeze, among children. In the latter, dog exposure only in the first year of life increased the risk for wheezing and cough/phlegm, whereas the presence of a dog lifetime seemed a protective factor (though not significant) for all symptoms/diagnoses; negative relations (but not significant) suggested a protective effect by the cat for asthma, independently of exposure period. Among adolescents, the presence of a dog both lifetime and only in the first year of life was significantly related to cough/phlegm; except for rhino-conjunctivitis, all symptoms/diagnoses were negatively related to the presence of a cat lifetime (though not significantly). In conclusion, our results confirmed the effects of mould exposure, especially when it occurs early, on the prevalence of respiratory disorders such as asthma, rhinitis and cough in the pediatric age. The complex relations between keeping a dog or cat at home and respiratory/allergic symptoms/diseases in childhood warrants further studies.

  16. Any benefits of probiotics in allergic disorders?

    PubMed

    Ozdemir, Oner

    2010-01-01

    Development of the child's immune system tends to be directed toward a T-helper 2 (Th2) phenotype in infants. To prevent development of childhood allergic/atopic diseases, immature Th2-dominant neonatal responses must undergo environment-driven maturation via microbial contact in the early postnatal period. Lactic acid bacteria and bifidobacteria are found more commonly in the composition of the intestinal flora of nonallergic children. Epidemiological data also showed that atopic children have a different intestinal flora from healthy children. Probiotics are ingested live health-promoting microbes that can modify intestinal microbial populations in a way that benefits the host; and enhanced presence of probiotic bacteria in the intestinal microbiota is found to correlate with protection against atopy. There is insufficient but very promising evidence to recommend the addition of probiotics to foods for prevention and treatment of allergic diseases, especially atopic dermatitis. Clinical improvement especially in allergic rhinitis and IgE-sensitized (atopic) eczema has been reported too. Literature data for food allergy/hypersensitivity and asthma are not adequate for this guaranteed conclusion; however, clinical benefit of probiotic therapy depends on numerous factors, such as type of bacterium, dosing regimen, delivery method, and other underlying host factors, e.g., the age and diet of the host. The selection of the most beneficial probiotic strain, the dose, and the timing of supplementation still need to be determined. Accordingly, probiotics can not be recommended generally for primary prevention of atopic disease; and if probiotics are used in atopic infants/children for any reason, such as therapy or prevention, cautionary approach ought to be taken.

    Allergic rhinitis is associated with several complications, including sleep disorders. The Children's Sleep Habits Questionnaire has been recently translated and validated in Portuguese for the evaluation of sleep disorders in children. To assess sleep disorders in children with moderate to severe persistent allergic rhinitis and to correlate the findings with disease severity markers. We evaluated 167 children (4-10 years), 112 with allergic rhinitis and 55 controls. Parents/guardians of the children answered the Children's Sleep Habits Questionnaire, consisting of 33 questions divided into eight subscales, which refers to the previous week. Patients with rhinitis were also evaluated regarding the score of nasal and extra-nasal symptoms related to the previous week and the peak nasal inspiratory flow. There were no significant differences between groups of different age. All patients with rhinitis were being treated with nasal topical corticosteroids. The total Children's Sleep Habits Questionnaire score was significantly higher among children with rhinitis than in controls (median 48 vs. 43, p<0.001). Significantly higher values were also observed for the parasomnia (9 vs. 8), respiratory disorders (4 vs. 3) and daytime sleepiness (14 vs. 12) subscales. Among the patients with rhinitis, no significant correlation was observed between the total Children's Sleep Habits Questionnaire score and disease activity variables, but moderate correlations were observed for the respiratory distress subscale vs. nasal symptom score (r=0.32) and vs. extra-nasal symptom score (r=0.32). Children with moderate to severe persistent allergic rhinitis, even when submitted to regular treatment, have a higher frequency of sleep disorders than controls, particularly concerning nocturnal breathing disorders, daytime sleepiness, and parasomnias. The intensity of sleep disorders found in some subscales was correlated with objective markers of allergic rhinitis severity. Copyright © 2017

    We previously reported a higher prevalence of nasal obstructive disorders (NOD) in pediatric patients with persistent allergic rhinitis (PER) not responding to medical treatment. The aim of this study was to determine the impact of NOD on quality of life (QoL) in this population. Real-life prospective study including 142 patients (41 children, 6-11 years old and 101 adolescents, 12-17 years old) with moderate and severe PER. After 2 months of medical treatment (intranasal steroids and antihistamines), patients were asked whether their symptoms had improved (yes/no) and classified accordingly in R, responders and NR, non-responders. Nasal symptoms (visual analog scale, VAS), NOD (nasal endoscopy), and QoL (PRQLQ, AdolQRLQ) were also assessed. Sixty-nine adolescents and 24 children were included in the NR group. NR presented worse QoL overall scores in adolescents (3.16±1.1 vs 1.63±0.99; P=.00001) and children (2.19±0.82 vs 1.51±0.77, P=.02). Medical treatment failure was associated with worse outcomes in QoL (adolescents OR: 1.6, P<.0001; children OR: 1.04, P=.036). Female adolescents presented worse QoL scores than males (3.19 vs 2.36, P=.001). The presence of obstructive septal deviation (OR: 1.02, P=.005), obstructive turbinate hyperplasia (OR: 1.03, P=.0006), and coexistence of both (OR=2.06, P=.001) was associated with worse QoL in adolescents. A strong and highly significant correlation was found between nasal symptoms VAS and QoL. The presence of NOD, particularly in adolescents, is associated with poor QoL outcomes. Assessment of NOD in pediatric PER should be considered an essential approach to determine the response to treatment and its impact on patient's QoL. © 2017 EAACI and John Wiley and Sons A/S.

    The prevalence of asthma and allergic disorders in childhood is increasing in many parts of the world. This review focuses on recent findings with regard to environmental risk factors and their manipulation in the primary prevention of these diseases in childhood. Recent studies have failed to resolve the controversy on the subject of exposure to indoor aeroallergens and the risk of sensitization and asthma in childhood. Bronchiolitis due to respiratory syncytial virus in infancy is associated with a significant increase in risk of asthma, but not atopy. In the prevention of these diseases, the effects of breastfeeding are controversial, with studies showing a protective effect in children without allergic predisposition, but other studies showing no effect or even the potential for an increased asthma risk. A significant reduction in the prevalence of doctor-diagnosed asthma at 7 years was found in a randomized controlled multifaceted (reduction of inhaled and ingested allergens) intervention study of high-risk infants. Other intervention measures, such as an education program on how to reduce exposure, the use of probiotics, and immunization against infections, all showed some protective effects. More research is required, especially with regard to longer periods of follow-up for all current intervention studies aimed at reducing exposure, the onset and duration of intervention, and other novel intervention measures in the primary prevention of asthma and allergic diseases in childhood.

    Completion of the human genome project and rapid progress in genetics and bioinformatics have enabled the development of large public databases, which include genetic and genomic data linked to clinical health data. With the massive amount of information available, clinicians and researchers have the unique opportunity to complement and integrate their daily practice with the existing resources to clarify the underlying etiology of complex phenotypes such as allergic diseases. The genome itself is now often utilized as a starting point for many studies and multiple innovative approaches have emerged applying genetic/genomic strategies to key questions in the field of allergy and immunology. There have been several successes, which have uncovered new insights into the biologic underpinnings of allergic disorders. Herein, we will provide an in depth review of genomic approaches to identifying genes and biologic networks involved in allergic diseases. We will discuss genetic and phenotypic variation, statistical approaches for gene discovery, public databases, functional genomics, clinical implications, and the challenges that remain.

    Filaggrin gene (FLG) null mutations are considered associated with atopic dermatitis. This study was conducted to determine the prevalence of FLG null mutations R501X, 2282del4, R2447X and S3247X in the Croatian population and their role in the occurrence of allergic diseases including atopic dermatitis, allergic rhinitis, asthma and allergic contact dermatitis (ACD). Study enrolled 440 freshmen with defined allergic diseases by means of both present symptoms in International Study of Asthma and Allergies in Childhood questionnaire (relevant respiratory and/or skin symptoms) and markers of allergic sensitization (positive skin prick and/or patch test). FLG null mutations were successfully genotyped in 423 students of which 11 (2.6%) were carriers of FLG null mutation: 1/423 (0.2%) was heterozygous for R501X and 10/423 (2.4%) were heterozygous for 2282del4. No carriers of R2447X and S3247X mutations were identified. In wild-type FLG carriers (412 subjects), atopic dermatitis was present in 45 (11%), allergic rhinitis in 70 (17%) and allergic asthma in 29 (7%) students. Twenty-five of 393 (7%) patch-tested wild-type FLG carriers had ACD. Among 11 FLG null mutation carriers, four had one or more allergic diseases, and five had reported skin symptoms without defined allergic sensitization (positive skin prick test and/or patch test). FLG null mutations were not confirmed as a predictor of analysed allergic diseases, but were confirmed as an independent predictor of skin symptoms (OR 17.19, 95% CI 3.41-86.6, P < 0.001). Our results in general indicate a low frequency of FLG null mutations in the studied Croatian population supporting a theory of a latitude-dependent distribution of FGL null mutations in Europe, with a decreasing north-south gradient of R501X and 2282del4 mutation frequency. The relation between FLG null mutations and skin disorders was confirmed.

    Background Recent findings suggest that exposure to outdoor air pollutants may increase the risk of allergic rhinitis. The results of these studies are inconsistent, but warrant further attention. The objective of the study was to assess the effect of relation between exposure to urban air pollution and the prevalence allergic rhinitis among school children. Methods We conducted a nationwide cross-sectional study of 32,143 Taiwanese school children. We obtained routine air-pollution monitoring data for sulphur dioxide (SO2), nitrogen oxides (NOx), ozone (O3), carbon monoxide (CO), and particles with an aerodynamic diameter of 10 μm or less (PM10). A parent-administered questionnaire provided information on individual characteristics and indoor environments (response rate 92%). Municipal-level exposure was calculated using the mean of the 2000 monthly averages. The effect estimates were presented as odds ratios (ORs) per 10 ppb change for SO2, NOx, and O3, 100 ppb change for CO, and 10 μg/m3 change for PM10. Results In two-stage hierarchical model adjusting for confounding, the prevalence of allergic rhinitis was significantly associated with SO2 (adjusted odds ratio (OR) = 1.43, 95% confidence interval (CI): 1.25, 1.64), CO (aOR = 1.05, 95% CI: 1.04, 1.07), and NOx (aOR = 1.11, 95% CI: 1.08, 1.15). Contrary to our hypothesis, the prevalence of allergic rhinitis was weakly or not related to O3 (aOR = 1.05, 95% CI: 0.98, 1.12) and PM10 (aOR = 1.00, 95% CI: 0.99, 1.02). Conclusion Persistent exposure to NOx, CO, and SO2 may increase the prevalence of allergic rhinitis in children. PMID:16469096

    Summary Background The co-existence of allergic conditions, food allergy, eczema, allergic rhinitis, asthma and anaphylaxis is thought to be increasing. Analysis of primary healthcare data-sets offers the possibility to advance understanding about the changing epidemiology of multiple allergic disorders. Aim To investigate recent trends in the recorded incidence, lifetime prevalence and consulting behaviour of patients with multiple allergic disorders in England. Methods QRESEARCH is one of the world's largest national aggregated health databases containing the records of over nine million patients (including those who have left or died). Data were extracted on all patients with a recorded diagnosis of multiple allergic disorders, and annual age–sex standardized incidence and lifetime period prevalence rates were calculated for each year from 2001 to 2005. We also analysed the consulting behaviour of these patients when compared with the rest of the QRESEARCH database population. Results The age–sex standardized incidence of multiple allergic disorders was 4.72 per 1000 person-years in 2001 and increased by 32.9% to 6.28 per 1000 patients in 2005 (p<0.001). Lifetime age–sex standardized prevalence of a recorded diagnosis of multiple allergic disorders increased by 48.9% from 31.00 per 1000 in 2001 to 46.16 in 2005 (p<0.001). Over this period, the mean consultation rate to general practitioners for these patients increased from 4.68 to 4.90 consultations per person per year. Conclusions Recorded incidence and lifetime prevalence of multiple allergic disorders in England have increased substantially in recent years. PMID:19029357

    There is much evidence that the development of allergic disorders may be related to early exposure of allergens, including those in breastmilk. We have tried to find out whether avoidance of food and inhaled allergens in infancy protects against the development of allergic disorders in high-risk infants. In a prenatally randomised, controlled study 120 infants with family history of atopy and high (greater than 0.5 kU/l) cord-blood concentrations of total IgE were allocated randomly to prophylactic and control groups. In the prophylactic group (n = 58), lactating mothers avoided allergenic foods (milk, egg, fish, and nuts) and avoided feeding their infants these foods and soya, wheat, and orange up to the age of 12 months; the infants' bedrooms and living rooms were treated with an acaricidal powder and foam every 3 months, and concentrations of Dermatophagoides pteronyssinus antigen(Der p l) in dust samples were measured by enzyme-linked immunosorbent assay. In the control group (n = 62), the diet of mothers and infants was unrestricted; no acaricidal treatment was done and Der p l concentrations were measured at birth and at 9 months. A paediatric allergy specialist unaware of group assignment examined the infants for allergic disorders at 10-12 months. Odds ratios were calculated by logistic regression analysis for various factors with control for other confounding variables. At 12 months, allergic disorders had developed in 25 (40%) control infants and in 8 (13%) of the prophylactic group (odds ratio 6.34, 95% confidence intervals 2.0-20.1). The prevalences at 12 months of asthma (4.13, 1.1-15.5) and eczema (3.6, 1.0-12.5) were also significantly greater in the control group. Parental smoking was a significant risk factor for total allergy at 12 months whether only one parent smoked (3.97, 1.2-13.6) or both parents smoked (4.72, 1.2-18.2).

    This study explored the development and comorbidity of allergic diseases by analysing the relationship between allergic manifestations in infancy and at the age of 8. We included 5654 children born in Sweden in 2003 in a longitudinal study. Parents answered postal questionnaires when the children were six months and one, four-and-a-half and eight years of age. The response rate at eight years was 4051 (71.6%), and we analysed 3382 children with complete data. The number of manifestations in infancy increased the risk of allergic disease at eight years of age: 72% of children with one early manifestation were symptom free at 8, compared to 45% with two or more manifestations. Similar manifestations occurred in infancy and at the age of 8, for example recurrent wheeze increased the risk of doctor-diagnosed asthma by an adjusted odds ratio of 6.5. Eczema and food allergy independently increased the risk of all four allergic manifestations at eight years. Allergic disease at the age of 8 was related to the number of allergic manifestations in infancy. Manifestations were similar at both ages, suggesting an allergic march with the coexistence of disease patterns rather than the progressive development of one disease. ©2016 The Authors.

    Objective Previous studies have reported comorbidity of attention deficit and hyperactivity disorder (ADHD) and allergic diseases. The current study investigated ADHD like behavioral symptoms and parenting stress in pediatric allergic rhinitis. Methods Eighty-seven children (6-13 years old) with allergic rhinitis and 73 age- and sex-matched children of control group were recruited. Diagnosis and severity assessments of allergic rhinitis were determined by a pediatric allergist. The Parenting Stress Index-Short Form (PSI-SF), ADHD Rating Scale (ARS), and Child Behavior Checklist (CBCL) were completed by their mothers. Results In the allergic rhinitis group, the total PSI-SF score (p<0.01), ARS score (p<0.01), the subscale scores of the CBCL including somatization, attentional problems and emotional instability (p=0.01; p<0.01; p<0.01) and prevalence of ADHD (p=0.03) were significantly higher than those of the control group. Among mothers of children with allergic rhinitis, those of children with comorbid ADHD demonstrated significantly higher parenting stress than those without comorbid ADHD (p<0.01). Parenting stress was correlated with severity of child's allergic symptoms and the ARS total score (beta=0.50, p<0.01; beta=0.39, p<0.01). There was a significant correlation between allergic symptom severity and the ARS total score (B=8.4, SD=2.5, t=3.3, p<0.01). Conclusion This study demonstrated that ADHD symptoms were common in children with allergic rhinitis, and this factor increased parenting stress and disrupted the parent-child relationship. Routine evaluation and early management of ADHD symptoms in pediatric allergic rhinitis may benefit families of children with allergic rhinitis. PMID:25110499

    Self-reported non-allergic nasal symptom triggers in non-allergic ('vasomotor') rhinitis overlap with commonly identified environmental exposures in non-specific building-related illness. These include extremes of temperature and humidity, cleaning products, fragrances, and tobacco smoke. Some individuals with allergic rhinitis also report non-allergic triggers. We wished to explore the phenotypic overlap between allergic and non-allergic rhinitis by ascertaining self-reported non-allergic nasal symptom triggers among allergic rhinitics. Sixty subjects without work-related respiratory exposures or symptoms, aged 19-68 years, stratified by age, gender and (skin test-proven) allergic rhinitis status, were queried with regard to self-reported non-allergic nasal symptom triggers (aggregate score 0-8). In this sample, the number of self-reported non-allergic triggers was bimodal, with peaks at 1 and 5. Forty-two percent of seasonal allergic rhinitic subjects reported more than three non-allergic triggers, compared with only 3% of non-allergic non-rhinitics (P < 0.01). Subjects over 35 years were more likely to report one or more non-allergic triggers, particularly tobacco smoke (P < 0.05). Allergic rhinitics reported more non-allergic symptom triggers than did non-allergic, non-rhinitics. As indexed by self-reported reactivity to non-specific physical and chemical triggers, both non-allergic rhinitics and a subset of allergic rhinitics may constitute susceptible populations for non-specific building-related illness. Judging by self-report, a substantial subset of individuals with allergic rhinitis--along with all individuals with nonallergic rhinitis (by definition)--are hyperreactive to non-allergic triggers. There is overlap between these triggers (elicited in the process of obtaining a clinical diagnosis) and environmental characteristics associated with ''problem buildings.'' Since individuals with self-identified rhinitis report an excess of symptoms in most

    Although efforts to improve the classification of hypersensitivity/allergic diseases have been made, they have not been considered a top-level category in the International Classification of Diseases (ICD)-10 and still are not in the ICD-11 beta phase linearization. ICD-10 is the most used classification system by the allergy community worldwide but it is not considered as appropriate for clinical practice. The Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) on the other hand contains a tightly integrated classification of hypersensitivity/allergic disorders based on the EAACI/WAO nomenclature and the World Health Organization (WHO) may plan to align ICD-11 with SNOMED CT so that they share a common ontological basis. With the aim of actively supporting the ongoing ICD-11 revision and the optimal practice of Allergology, we performed a careful comparison of ICD-10 and 11 beta phase linearization codes to identify gaps, areas of regression in allergy coding and possibly reach solutions, in collaboration with committees in charge of the ICD-11 revision. We have found a significant degree of misclassification of terms in the allergy-related hierarchies. This stems not only from unclear definitions of these conditions but also the use of common names that falsely imply allergy. The lack of understanding of the immune mechanisms underlying some of the conditions contributes to the difficulty in classification. More than providing data to support specific changes into the ongoing linearization, these results highlight the need for either a new chapter entitled Hypersensitivity/Allergic Disorders as in SNOMED CT or a high level structure in the Immunology chapter in order to make classification more appropriate and usable.

  11. The Role of Thymic Stromal Lymphopoietin (TSLP) in Allergic Disorders

    Summary The importance of the epithelium in initiating and controlling immune responses is becoming more appreciated. For example, allergens contact first occurs at mucosal sites in exposed to the external environment such as the skin, airways and gastrointestinal tract. This exposure leads to the production of a variety of cytokines and chemokines that are involved in driving allergic inflammatory responses. One such product is thymic stromal lymphopoietin (TSLP). Recent studies, in both humans and mouse models, have implicated TSLP in the development and progression of atopy and atopic diseases. This review will discuss this work and place TSLP in the inflammatory cascade that leads to allergic disease. PMID:21109412

    Vitamin D deficiency (VDD) has been reported in very high rates in the U.S. population. Deficiency has been implicated in various diseases such as diabetes, high blood pressure, cardiovascular disease, and many cancers. It has also been implicated in several allergic disorders and immune system dysregulation. The National Health and Nutrition examination survey (NHANES) in 2005-2006 was a cross-sectional survey performed in the noninstitutionalized population of the United States by the Center for Disease Control and Prevention and National Center for Health Statistics. It consists of an extensive interview performed at home and an examination performed at a mobile center. An allergy questionnaire was provided as interview data on self-reported allergic diseases including allergic rhinitis, allergies, and atopic dermatitis. Data were collected using the question, "Has the doctor or other health professional ever told you that you have allergies?" The laboratory parameter of vitamin D < 10 ng/mL was used to define severe VDD. The data were analyzed by logistic regression with SAS Version 9.1 (SAS Institute, Inc., Cary, NC) using the Procedure survey methods. Of 10,348 people who participated in the 2005-2006 NHANES survey, our final sample consisted of 4979 people in whom serum 25-hydroxyvitamin D levels were completed after excluding subjects <20 years of age and those with missing vitamin D values. The VDD was positively correlated with prevalence of allergies. After adjusting the model for age, gender, race, smoking, alcohol, and educational status, the odds ratio still remained significant. There was also a positive correlation with allergy subtypes such as prevalence of rashes, sneezing, and sinus infections with low vitamin D. VDD related to the immune system dysregulation has been extensively reviewed.

    An analysis is made of the incidence of allergic diseases in 105 enuretic boys and girls, in their parents and siblings, and in matched controls. There is an increased incidence of hay fever, urticaria and food and drug allergies in enuretic boys. There is an increased incidence of enuresis in the parents of enuretic children. Enuretic children and their fathers are significantly more prone to develop urinary infections than are controls; there is also an increased incidence in urinary infections in their mothers, but numbers are insufficient to indicate that this is significant.

    Data on the association between breastfeeding and allergies are conflicting. To investigate the relationship between the duration and exclusivity of breastfeeding and the prevalence of wheeze, asthma and eczema in young Japanese children. Study subjects were 1957 children aged 3 years. Data on breastfeeding, allergic symptoms and potential confounders were collected using a questionnaire. Outcomes were defined according to the criteria of the International Study of Asthma and Allergies in Childhood. Adjustment was made for sex, number of siblings, household smoking, paternal and maternal history of asthma, atopic eczema and allergic rhinitis, and paternal and maternal educational levels. The prevalence values of symptoms of wheeze, asthma and eczema in the previous 12 months were respectively 22.1%, 8.9% and 17.3%. Exclusive breastfeeding for > or =4 months vs. <4 months was associated with a lower prevalence of asthma. The duration of breastfeeding, regardless of exclusivity, for > or =6 months tended to be associated with a lower prevalence of asthma. There was no appreciable association between breastfeeding and wheeze or eczema. Data from this study indicate that breastfeeding may be associated with a lower prevalence of asthma among young Japanese children.

    The underlying denominators and treatment targets in allergic disorders may be outlined as aberrant barrier functions of the skin epithelium and gut mucosa and dysregulation of the immune response to ubiquitous environmental antigens. Dietary methods to control symptoms and reduce the risk of allergic disease have hitherto focused on elimination diets, alone or in combination with other environmental measures. The results have not been satisfactory regarding long-term prevention, and new approaches are urgently needed. Realization of this, together with the demonstration that the immunophysiologic regulation in the gut depends on the establishment of the healthy gut microbiota, has led to the introduction of novel modes of therapeutic intervention on the basis of the consumption of monocultures and mixed cultures of beneficial live probiotic microorganisms. The current aims of intervention are to avert deviant microbiota development, strengthen the gut barrier function, and alleviate abnormal immune responsiveness. Specific probiotics, selected from members of the healthy intestinal microbiota most of them belonging to Lactobacillus or Bifidobacterium, aid in degradation/structural modification of enteral antigens, regulation of the secretion of inflammatory mediators, and direction of the development of the immune system during the critical period of life when these functions are immature and inexperienced and the risk of allergic disease is heightened. In humans, documented effects have been reported for alleviation of intestinal inflammation, normalization of gut mucosal dysfunction, and down-regulation of hypersensitivity reactions, thereby preferentially targeting allergic conditions with intestinal involvement. The probiotic performance of strains differs; each probiotic strain is a unique organism itself with specific properties that cannot be extrapolated from other, even closely related, strains. Moreover, it would seem simplistic to assume that a single

    We summarize current knowledge on the genetic determinants of skin barrier deficiency in relation to eczema and disease progression to other allergic manifestations. There is increasing evidence that impairment of epidermal barrier function is not only a risk factor for the development of eczema but also for disease progression to allergic airway disease and food allergy. Support comes from recent association studies linking genetic variants in epidermal genes with eczema and food allergy, from monogenic diseases with severe skin barrier defects which display multiple allergic manifestations, and from mouse models providing a mechanism from skin inflammation to allergic reactions in the lung and intestine. The key role of the skin barrier defect in the development of eczema and eczema-associated allergic diseases may have important implications for prevention and treatment strategies. Initial clinical trials with moisturizing creams revealed promising results for the prevention of eczema in early infancy. Their long-term effects will be critical to demonstrate the potential benefit of barrier repair therapy in allergic disease prevention.

We present a practical method for office use, and review our experience with 423 patients in whom the exam was performed. 49% had an abnormal nasal mucosa and middle meatus, site related to ethmoidal and maxillary sinus drainage. In 23 patients we found abnormal turbinates, either clefting, polypoidal changes, degeneration or concha bullosa; most of these findings were not appreciated after routine speculum examination. 7% of our patients had mucosal changes in the area related to the olfactory epithelium, edema and inflammation related to taste and smell disorders. 56 patients had inflammation and hypertrophy in adenoids, 50% of these with some degree of auditory canal obstruction (Eustaquian orifice). In the inferior pharynx and larynx, 58 patients had abnormalities, inflammation in glotic area (8%) due to speech dysfunction. They required speech therapy 4% (14 patients) with abnormal vocal cords, polyps (5), paralysis (4). 2 patients with carcinoma, were referred for biopsy and specific treatment. After gaining sufficient expertise rhinofaringolaryngoscopy is a useful and safe procedure which enhances the diagnostic ability of the practicing allergist/immunologist to evaluate complains referable to the upper airways.

    Allergic disorders are not usually life-threatening conditions but they impair the person's ability to function. It thus adversely affects the psychological wellbeing and quality of life. These implications of allergic disorders can be minimized if strategies are planned for its early identification followed by appropriate interventions. To find out the prevalence and risk factors of allergic disorders. Data was collected by house to house survey among participants aged 18 years and above using a standardized allergy assessment questionnaire. Mean age of the 400 participants was 42.8±14.7 years. Majority 105(26.2%) were in the age group 36 to 45 years. Majority were females 287(71.7%) and were house wives 217(54.2%). Majority of participants were of upper socio economic class 98(44.7%) out of 219 and majority were from urban areas 326(81.5%). The prevalence of allergy among participants was found to be 115(28.7%). Out of these 115, 37(32.2%) had possibility of allergy, 60(52.2%) had probability of allergy and the rest 18(15.6%) had very high likelihood for allergy. People residing in semi urban areas had increased risk of allergy (p=0.024) than those from urban areas. The prevalence of asthma was 30(7.5%) and skin allergy was 23(5.8%). Most common precipitating factors for allergy were dust exposure 103(25.8%) followed by seasonal changes 71(17.8%). Family history of allergy was associated with allergy among participants (p<0.001). Usage of firewood was associated with symptoms of respiratory allergy among participants (p=0.01). The study revealed some important determinants of allergic disorders which have important implications to frame appropriate prevention and health educational strategies.

    Reports of frequent manifestation of allergic diseases in children with attention deficit hyperactivity disorder (ADHD) have been the subject of mounting clinical interest. However, evidence supporting the association between ADHD and allergies is inconsistent and has yet to be systematically reviewed. The objective of this study was to compile and assess available studies on the association between ADHD and allergic diseases in children. A comprehensive search using MEDLINE, EMBASE, the Cochrane library, and CINAHL databases was completed in 23 November 2015. The inclusion criteria for studies were that the research assessed allergic diseases in children, 18 years of age and younger, with a diagnosis of ADHD and that a distinct comparison group was incorporated. Any comparative studies, encompassing both randomized controlled trials and observational studies, were considered for inclusion. Two review authors independently assessed the quality of the selected studies by the use of validated assessment tools, performed data extraction and conducted meta-analysis according to Cochrane Collaboration guidelines. Five eligible studies were included in this systematic review. Of these studies, three were case-control and two were cross sectional studies. A majority of information from the five studies was classified as having low or unclear risk of bias. The meta-analysis showed an association between children with ADHD and asthma compared with the control groups (OR: 1.80, 95% CI: 1.57 - 2.07; five studies, low quality of evidence), but did not indicate an association between food allergy and ADHD (OR: 1.13, 95% CI: 0.88 - 1.47; three studies very low quality of evidence). The odds of experiencing allergic rhinitis, atopic dermatitis, and allergic conjunctivitis were slightly higher in children with ADHD compared with control groups, though a substantial statistical heterogeneity was notable in the overall effect estimates. The findings from this review and meta

    OBJECTIVES--To compare the prevalence of asthma and allergic disorders among children in Munich, western Germany, and Leipzig, eastern Germany, where environmental exposure, particularly air concentrations of sulphur dioxide and particulate matter, and living conditions have differed over the past 45 years. DESIGN--Prevalence surveys among school-children aged 9-11 years in Leipzig and Munich. Self completion of written questionnaire by the children's parents and lung function measurements. SUBJECTS--1051 children in Leipzig and 5030 in Munich. SETTING--Primary schools. MAIN OUTCOME MEASURES--Reported lifetime prevalence of asthma and allergic disorders, and bronchial hyperresponsiveness assessed by cold air inhalation challenge. RESULTS--The lifetime prevalence of asthma diagnosed by a doctor was 7.3% (72) in Leipzig and 9.3% (435) in Munich; prevalence of wheezing were 20% (191) and 17% (786) respectively. The prevalence of diagnosed bronchitis was higher in Leipzig than Munich (30.9% (303) v 15.9% (739); p < 0.01). A significant drop in forced expiratory volume (> 9%) after cold air challenge was measured in 6.4% (57) of children in Leipzig and in 7.7% (345) of those in Munich. Hay fever (2.4% (24) v 8.6% (410); p < 0.01) and typical symptoms of rhinitis (16.6% (171) v 19.7% (961); p < 0.05) were reported less often in Leipzig than in Munich. CONCLUSIONS--No significant differences were seen in the lifetime prevalence of asthma, wheezing, and bronchial hyperresponsiveness between children in Leipzig and Munich. The lifetime prevalence of bronchitis was higher in Leipzig than in Munich. The lower prevalence rates of allergic disorders in Leipzig could point toward aetiological factors that are associated with Western lifestyle and living conditions. PMID:1486303

    The prevalence of allergic disorders has increased over the past few decades and the quality of life has been significantly influenced at least for the allergic subjects. Allergen avoidance is thought to be the best way of preventing clinical manifestation of the disease, however, it is not possible for some allergens, and other pharmacological and/or immunological treatment has to be made. Repetitive injection of sensitized allergens to the patients (immunotherapy) is the only known curative approach to the disease even though the exact mechanism is not clear to date. Crude extract of allergens has lots of shortcomings which might arouse unexpected results. Genetic engineering and recombinant allergens are thought to be one of the alternative ways to overcome these limitations. Genetic engineering could facilitate the investigation of immune responses of the subjects especially on B cell and T cell epitopes, and produce the therapeutic allergens which might minimize the possible side effects. Furthermore, conjugation of immuno-modulatory molecules such as CpG-ODN, cytokines, or toxins which could act specifically to the given allergens, and maleylation of the allergens could maximize the prophylactic or therapeutic effect. Immunotherapies for the pollen allergy and insect sting allergy have been thought to be successful. House dust mite allergy and cockroach allergy have been reported less beneficial by immunotherapeutic approaches. Cockroaches are one of the most important causes of asthma, and severe complications are often reported in the children in city dwellers with low-incomes. The studies of the biological functions of cockroach allergens and the use of recombinant allergens should allow understanding of mechanisms of cockroach-elicited allergic disorders and development of allergen-specific and sensitive diagnostics and tailored therapeutic approaches in the future.

    Biologic agents (also termed biologicals or biologics) are therapeutics that are synthesized by living organisms and directed against a specific determinant, for example, a cytokine or receptor. In inflammatory and autoimmune diseases, biologicals have revolutionized the treatment of several immune-mediated disorders. Biologicals have also been tested in allergic disorders. These include agents targeting IgE; T helper 2 (Th2)-type and Th2-promoting cytokines, including interleukin-4 (IL-4), IL-5, IL-9, IL-13, IL-31, and thymic stromal lymphopoietin (TSLP); pro-inflammatory cytokines, such as IL-1β, IL-12, IL-17A, IL-17F, IL-23, and tumor necrosis factor (TNF); chemokine receptor CCR4; and lymphocyte surface and adhesion molecules, including CD2, CD11a, CD20, CD25, CD52, and OX40 ligand. In this task force paper of the Interest Group on Biologicals of the European Academy of Allergy and Clinical Immunology, we review biologicals that are currently available or tested for the use in various allergic and urticarial pathologies, by providing an overview on their state of development, area of use, adverse events, and future research directions. © 2015 John Wiley & Sons A/S.

    Sleep related movement disorders (SRMD) are characterized by simple, stereotyped movements occur during sleep, with the exception of restless legs syndrome (RLS). RLS has the following essential features; an urge to move the legs usually accompanied by uncomfortable sensation in the legs, improvement of symptoms after movement (non-stereotypical movements, such as walking and stretching, to reduce symptoms), and symptoms occur or worsen during periods of rest and in the evening and night. However, RLS is closely associated with periodic limb movement, which shows typical stererotyped limb movements. In the International Classification of Sleep Disorders, 3rd edition, sleep disturbances or daytime symptoms are prerequiste for a diagnosis of SRMD. We here review diagnosis and treatment of SRMD.

    Nasal obstruction is recognized as an important cause of sleep disordered breathing. Congestion of the nasal mucosa and obstruction are common symptoms of allergic rhinitis. Daytime sleepiness is a common finding in symptomatic allergic rhinitis. Effective therapy of the nasal congestion of allergic rhinitis should alter sleep patterns in patients with symptomatic allergic rhinitis. To measure objective changes in polysomnograms (sleep studies) of children with allergic rhinitis before and after therapy with intranasal budesonide and to measure changes in the quality of life of these patients during treatment. Open clinical trial with objective measurements (polysomnography) and subjective data (Rhinitis Quality of Life Questionnaire [RQLQ]). Evaluations were performed before, during, and at completion of therapeutic intervention. The 14 studied children tolerated the procedures and treatment without problems. The mean number of sleep arousals per hour (all apneas and hypopneas) decreased from a baseline of 8.4 to 1.2 (P = .005) after treatment. The change was mainly in hypopneic episodes (7.5-0.9, P = .003). Objective responses on the RQLQ showed improvements consistent with improved sleep and lessened rhinitis symptoms. Decreasing the nasal congestion associated with allergic rhinitis can improve sleep measured by objective sleep studies and lead to improvement in daytime quality of life.

    2011-01-01

    Allergic rhinitis is a common disorder that is strongly linked to asthma and conjunctivitis. It is usually a long-standing condition that often goes undetected in the primary-care setting. The classic symptoms of the disorder are nasal congestion, nasal itch, rhinorrhea and sneezing. A thorough history, physical examination and allergen skin testing are important for establishing the diagnosis of allergic rhinitis. Second-generation oral antihistamines and intranasal corticosteroids are the mainstay of treatment. Allergen immunotherapy is an effective immune-modulating treatment that should be recommended if pharmacologic therapy for allergic rhinitis is not effective or is not tolerated. This article provides an overview of the pathophysiology, diagnosis, and appropriate management of this disorder. PMID:22166009

    The TH17 lineage of T cells and its canonical cytokine IL-17 have been the focus of many recent studies in autoimmune, allergic, and infectious disease. In this review, we will briefly discuss the current knowledge about the role of these cells and IL-17 in a spectrum of disorders. It is clear that IL-17 plays pathogenic roles in certain conditions while the same pathway is critically important to immunity in others. Targeting of TH17 cells or IL-17 therapeutically may impart many benefits, but this approach is not without potentially serious implications regarding host defense. These issues will be discussed herein as we evaluate pharmacological approaches targeting this pathway that are just beginning to be fully tested in human disease. PMID:23760974

    Background. Latex allergy is one of the major health concerns and allergic reactions to latex may be serious and fatal. Purpose. In this study, we sought to determine the frequency of latex hypersensitivity in a group of allergic Egyptian infants and children and its relation to the history provided by the patients or caregivers. Methods. We consecutively enrolled 400 patients with physician diagnosed allergic diseases. The study measurements included clinical evaluation for the site and duration of allergy, history suggestive of latex allergy, family history of allergy, and skin prick testing (SPT) using a commercial latex extract. Results. The study revealed that 16/400 (4%) patients had positive SPT; 11 of them only had positive history of sensitivity to latex. Positive latex SPT was reported in 3.4% (11/326) of patients with bronchial asthma, 5.9% (7/118) of patients with skin allergy, and 4.5% (2/44) of patients with allergic rhinitis. SPT was positive in 7.4% (4/54) of patients with concomitant respiratory and skin allergy. Latex SPT was more specific than sensitive (97.69% and 77.77%, resp.) with a negative predictive value of 99.47%. Conclusion. Although underrecognized, latex is an important allergen in the pediatric age group with a sensitization frequency of 4% among allergic children. It was observed to be especially associated with multiple allergic diseases coexisting in the same patient. Pediatric allergologists should educate their patients on latex allergy and encourage the use of latex-free products. PMID:25505988

    Background Although an inverse relationship between number of siblings and likelihood of allergic disorders has been shown in many epidemiological studies, the biological mechanism underlying this phenomenon has not yet been identified. There is no epidemiological research regarding the sibling effect on allergic disorders in Japanese adults. The current cross-sectional study examined the relationship between number of siblings and prevalence of allergic disorders among adult women in Japan. Methods Subjects were 1745 pregnant women. This study was based on questionnaire data. The definitions of wheeze and asthma were based on criteria from the European Community Respiratory Health Survey whereas those of eczema and rhinoconjunctivitis were based on criteria from the International Study of Asthma and Allergies in Childhood. Adjustment was made for age, region of residence, pack-years of smoking, secondhand smoke exposure at home and at work, family history of asthma, atopic eczema, and allergic rhinitis, household income, and education. Results The prevalence values of wheeze, asthma, eczema, and rhinoconjunctivitis in the past 12 months were 10.4%, 5.5%, 13.0%, and 25.9%, respectively. A significant inverse exposure-response relationship was observed between the number of older siblings and rhinoconjunctivitis, but not wheeze, asthma, or eczema (P for trend = 0.03); however, the adjusted odds ratio (OR) for having 2 or more older siblings was not significant although the adjusted OR for having 1 older sibling was statistically significant (adjusted OR = 0.71 [95% CI: 0.56-0.91]). Number of total siblings and number of younger siblings were not related to wheeze, asthma, eczema, or rhinoconjunctivitis. Conclusions This study found a significant inverse relationship between the number of older siblings and the prevalence of rhinoconjunctivitis among pregnant Japanese women. Our findings are likely to support the intrauterine programming hypothesis; however, we could

    2014-01-01

    Protease activated receptors (PARs) have been recognized as a distinctive four-member family of seven transmembrane G protein-coupled receptors (GPCRs) that can be cleaved by certain serine proteases. In recent years, there has been considerable interest in the role of PARs in allergic inflammation, the fundamental pathologic changes of allergy, but the potential roles of PARs in allergy remain obscure. Since many of these proteases are produced and actively involved in the pathologic process of inflammation including exudation of plasma components, inflammatory cell infiltration, and tissue damage and repair, PARs appear to make important contribution to allergy. The aim of the present review is to summarize the expression of PARs in inflammatory and structural cells, the influence of agonists or antagonists of PARs on cell behavior, and the involvement of PARs in allergic disorders, which will help us to better understand the roles of serine proteases and PARs in allergy.

    Systemic low-grade inflammation has been demonstrated in a range of the frequent noncommunicable diseases (NCDs) proposing a shared mechanism, but is largely unexplored in relation to allergic sensitization. We therefore aimed to investigate the possible association with childhood allergic sensitization. High-sensitivity C-reactive protein (hs-CRP), interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α), and chemokine (C-X-C motif) ligand 8 (CXCL8) were measured in plasma at age 6 months (N = 214) and 7 years (N = 277) in children from the Copenhagen Prospective Studies on Asthma in Childhood2000 (COPSAC2000 ) birth cohort. Allergic sensitization against common inhalant and food allergens was determined longitudinally at ages ½, 1½, 4 and 6 years by specific IgE assessments and skin prick tests. Associations between inflammatory biomarkers and sensitization phenotypes were tested with logistic regression and principal component analyses (PCAs). Adjusted for gender, recent infections, and a CRP genetic risk score, hs-CRP at 7 years was associated with concurrent elevated specific IgE against any allergen [adjusted OR (aOR) = 1.40; 95% CI, 1.14-1.72; P = 0.001], aeroallergens (aOR, 1.43; 1.15-1.77; P = 0.001), food allergens (aOR, 1.31; 95% CI, 1.02-1.67; P = 0.04), sensitization without any clinical allergy symptoms (aOR = 1.40; 1.06-1.85; P = 0.02), and with similar findings for skin prick tests. The other inflammatory markers were not univariately associated with sensitization, but multiparametric PCA suggested a specific inflammatory response among sensitized children. Inflammatory markers at age 6 months were not associated with subsequent development of sensitization phenotypes. Elevated hs-CRP is associated with allergic sensitization in school-aged children suggesting systemic low-grade inflammation as a phenotypic characteristic of this early-onset NCD. © 2016 John Wiley & Sons A/S.

    Background: Occupational contact dermatitis, especially in hand, is one of the most common occupational disorders. The present study aimed at evaluating patients with occupational allergic contact dermatitis (ACD) caused by common allergens based on occupation type and disease history. Methods: This cross-sectional study aimed at evaluating the data of the patients with probable diagnosis of ACD in Center for Research and Training in Skin Diseases and Leprosy (CRTSDL) in Iran. In the present study, 946 patients were assessed from different regions of Iran. One hundred fifty-one cases with positive patch test and relevant exposure were entered into the study; data related to their occupation and disease activity history were evaluated and recorded. Then, factors related to disease activity history were assessed considering the occupational groups and common exposures. Results: Nickel sulphate was the most common allergen in the 151 patients. Disease activity was constant in 29.8% of the patients; it increased in 27.8%, and decreased just before doing the patch test in 42.4%. Of the patients, 52.3% were getting worse during the working days. Occupational groups were significantly different in age and gender. Disease duration was also different in the occupational groups (p=0.001). The least disease duration was observed in healthcare workers, and the most in service workers. Lesions in the foot were related to period of employment. In administrative work group, (teachers, technicians and housewives) disease activity was decreased in the most cases, while it was increased in most patients of service workers (p=0.086). Conclusion: The present study, similar to previous reports, revealed that nickel sulphate is the most common allergen in ACD cases. Moreover, it was found that the symptoms of disease activity remained constant or increased in a significant proportion of the cases during the working days. Therefore, these workers should seriously follow up on this matter

    MED12 is a member of the large Mediator complex, which has a critical and central role in RNA polymerase II transcription. As a multiprotien complex, Mediator regulates signals involved in cell growth, development and differentiation, and it is involved in a protein network required for extraneuronal gene silencing and also functions as a direct suppressor of Gli3-dependent Sonic hedgehog signaling. This may may explain its role in several different X-linked intellectual disability syndromes that share some overlapping clinical features. This review will compare and contrast four different clinical conditions that have been associated with different mutations in MED12, which is located at Xq13. To date, these conditions include Opitz–Kaveggia (FG) syndrome, Lujan syndrome, Ohdo syndrome (Maat-Kievit-Brunner type, or OSMKB), and one large family with profound X-linked intellectual disability due to a novel c.5898insC frameshift mutation that unlike the other 3 syndromes, resulted in affected female carriers and truncation of the MED12 protein. It is likely that more MED12 mutations will be detected in sporadic patients and X-linked families with intellectual disability and dysmorphic features as exome sequencing becomes more commonly utilized, and this overview of MED12-related disorders may help to correlate MED12 genotypes with clinical findings.

    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".

    The role of traffic-related air pollution in the initiation of allergic disorders in children is still not clearly understood. The present prospective study examined the relation between proximity of the home during pregnancy to the nearest main road, which was used as a surrogate for traffic-related air pollutants, and the risk of allergic disorders in Japanese infants in an urban area. Subjects were 756 mother-child pairs. Distance of each subject's home during pregnancy from the center line of all of the 235 main roads in Osaka Prefecture was computed using geographical information system software. The first survey during pregnancy and the second survey between 2 and 9 months post-partum collected information on potential confounding factors. In the third survey, which was from 16 to 24 months post-partum, a self-administered questionnaire included questions on allergic disorders. In the third survey, 22.1% and 18.7% of infants became positive for wheeze and atopic eczema based on criteria of the International Study of Asthma and Allergies in Childhood (ISAAC), respectively. The risk of doctor-diagnosed asthma and doctor-diagnosed atopic eczema was 4.4% and 8.9%, respectively. A shorter distance of the residence during pregnancy from the nearest main road was associated with an increased risk of doctor-diagnosed asthma and atopic eczema (adjusted odds ratios for comparison of <50 m with 200 m or more = 4.01 and 2.26, 95% confidence intervals: 1.44-11.24 and 1.08-4.59, p for trend = 0.02 and 0.03, respectively). No evident relationships were observed between the distance of the residence during pregnancy from the nearest main road and the risk of wheeze or atopic eczema based on the ISAAC criteria. It was difficult to distinguish the effect of the pre-natal from the post-natal exposure because most subjects lived at the same home address both before and after childbirth. Our results are likely to support the hypothesis that intrauterine exposure to traffic-related

    Dysmenorrhea is a common symptom secondary to various gynecological disorders, but it is also represented in most women as a primary form of disease. Pain associated with dysmenorrhea is caused by hypersecretion of prostaglandins and an increased uterine contractility. The primary dysmenorrhea is quite frequent in young women and remains with a good prognosis, even though it is associated with low quality of life. The secondary forms of dysmenorrhea are associated with endometriosis and adenomyosis and may represent the key symptom. The diagnosis is suspected on the basis of the clinical history and the physical examination and can be confirmed by ultrasound, which is very useful to exclude some secondary causes of dysmenorrhea, such as endometriosis and adenomyosis. The treatment options include non-steroidal anti-inflammatory drugs alone or combined with oral contraceptives or progestins. PMID:28944048

    This article reviews the sleep-related movement disorders, including restless legs syndrome (RLS; Willis-Ekbom disease), periodic limb movement disorder, rhythmic movement disorders, sleep-related bruxism, and sleep-related leg cramps. The prevalence of clinically significant RLS is 1.5% to 3.0%. The pathophysiology of RLS may involve abnormal iron transport across the blood-brain barrier and down-regulation of putaminal D2 receptors. The availability of the rotigotine patch provides an additional form of dopaminergic therapy for RLS. Calcium channel alpha-2-delta ligands (gabapentin, gabapentin enacarbil, and pregabalin) provide alternative therapies for RLS especially in patients with augmentation, impulse control disorders, or hypersomnia induced by dopamine agonists. Long-term use of opioid medication is safe and effective for refractory cases of RLS. RLS is a common disorder causing considerable morbidity. Accurate diagnosis and appropriate investigations are essential. Many effective therapies are available, but the side effects of each class of medication should be considered in determining optimal treatment. Periodic limb movements of sleep, bruxism, and rhythmic movement disorders are sleep-related phenomena often accompanying other sleep disorders and only sometimes requiring primary therapy. Sleep-related leg cramps are generally idiopathic. Management is challenging with few effective therapies.

    Pregnancy-related liver disorders accounted for 8% of all maternal deaths at our center from 1999 to 2011. Of the three pregnancy-related liver disorders (acute fatty liver of pregnancy (AFLP), HELLP (Hemolysis, elevated liver enzymes, low platelets) syndrome and pre-eclamptic liver dysfunction, which can lead to adverse maternal and fetal outcome, AFLP is most typically under - diagnosed. Risk of maternal death can be minimised by timely recognition and early/aggressive multi-specialty management of these conditions. Urgent termination of pregnancy remains the cornerstone of therapy for some of these life threatening disorders, but recent advancements in our understanding help us in better overall management of these patients. This review focuses on various aspects of pregnancy-related liver disorders.

The aim of this study was to evaluate sleep disorders in Latin-American children (4-10 years) from nine countries, with persistent asthma (A) and/or allergic rhinitis (AR) and in normal controls (C). Parents from 454 C children and 700 A and/or AR children followed up in allergy reference clinics completed the Children's Sleep Habits Questionnaire (CSHQ) which is a retrospective one-week questionnaire composed of 33 questions composed of seven subscales (bedtime resistance, sleep duration, sleep anxiety, night wakings, parasomnias, sleep-disordered breathing and daytime sleepiness). The total scale of CSHQ and the subscales were compared between groups C and A+AR, A (n=285) vs. AR (n=390), and between controlled A (CA, n=103) vs. partially controlled/uncontrolled A (UA, n=182). The comparison between C and A+AR showed no significant differences in age (6.7 years vs. 7.0 years, respectively), mean Body Mass Index and total scale of CSHQ (53.3 vs. 63.2, respectively) and the subscales were significantly higher in the A+AR group. Comparison between groups A and AR, except for sleep anxiety, showed significantly higher values for CSHQ total scale (66.9 vs. 61.0, respectively) and subscales for group A. The UA group showed significantly higher values for total CSHQ scale and subscales in comparison to CA (71.1 vs. 59.4, respectively). Latin-American children with asthma and/or allergic rhinitis showed sleep disorders identified by the CSHQ when compared to normal controls. Despite being treated, asthma causes sleep impairment, especially when uncontrolled. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U. All rights reserved.

  6. Wheat-related disorders reviewed: making a grain of sense.

    Wheat-related disorders have become a growing area of clinical and scientific interest and can be categorized broadly as: autoimmune-mediated; allergic; and non-autoimmune/non-allergic conditions. Non-celiac gluten sensitivity (NCGS) and non-celiac wheat sensitivity (NCWS) present on this spectrum as disorders associated with adverse gastrointestinal and extra-intestinal manifestations following exposure to gluten and/or other wheat-related constituents. NCGS/NCWS is increasingly considered in patients with unexplained symptoms after the exclusions of celiac disease and wheat allergy. As objective diagnostic data and specific biomarkers are lacking, response to a gluten-free/wheat-free diet can confirm the presence of NCGS/NCWS. An association with irritable bowel syndrome has been detected, and the effects of other food components, such as fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, may contribute. Our organization and synthesis of extant knowledge pertaining to wheat-related disorders may advance current practice and research efforts toward an improved understanding of NCGS/NCWS as an evolving clinical entity.

    Background Sleep disordered breathing (SDB) and sleep disturbances have been reported to be associated with allergic rhinitis and asthma. However, population-based studies of this issue in the elderly are rare. Objective To investigate the impact of self-reported rhinitis and asthma on sleep apnea and sleep quality using polysomnography in an elderly Korean population. Methods A total of 348 elderly subjects who underwent one-night polysomnography study among a randomly selected sample were enrolled. Study subjects underwent anthropometric and clinical evaluations. Simultaneously, the prevalence and co-morbid status of asthma and allergic rhinitis, and subjective sleep quality were evaluated using a self-reported questionnaire. Results Ever-diagnosis of allergic rhinitis was significantly more prevalent in subjects with SDB compared with those without SDB. Subjects with an ever-diagnosis of allergic rhinitis showed a higher O2 desaturation index and mean apnea duration. Indices regarding sleep efficiency were affected in subjects with a recent treatment of allergic rhinitis or asthma. Waking after sleep onset was longer and sleep efficiency was lower in subjects who had received allergic rhinitis treatment within the past 12 months. Subjects who had received asthma treatment within the past 12 months showed significantly lower sleep efficiency than others. Conclusion Our study indicates that a history of allergic rhinitis is associated with increased risk of SDB in the elderly. Sleep disturbance and impaired sleep efficiency were found in the subjects who had received recent treatment of allergic rhinitis or asthma. Physicians should be aware of the high risk of sleep disorders in older patients with respiratory allergic diseases. PMID:28245272

    The review aims to give an update on the literature around traffic-related air pollution (TRAP) and allergic disease in the context of global urbanization, as the most populous countries in the world face severe TRAP exposure challenges. As research continues to show that gene-environment interactions and epigenetics contribute to the TRAP-allergy link, evidence around the links to climate change grows. Greenspace may provide a buffer to adverse effects of traffic on health, overall, but pose risks in terms of allergic disease. The link between traffic-related pollution and allergy continues to strengthen, in terms of supportive observational findings and mechanistic studies. Levels of TRAP across the world, particularly in Asia, continue to dramatically exceed acceptable levels, suggesting that the related adverse health consequences will accelerate. This could be counterbalanced by primary emission control and urban planning. Attention to combined effects of TRAP and allergen exposure is critical to avoiding misleading inferences drawn though examination only of isolated factors.

    In further studies on the use of frozen raw food as skin-testing material in patients with allergic disorders, the results of previous work were confirmed in a greater number of subjects using a larger number of foods: Tests with frozen raw foods by the scratch method induce true positive reactions of a larger size and in greater frequency than the corresponding commercial extracts by either the scratch or the intracutaneous method. Storage in the frozen state for several years does not affect the antigenic potency of the materials. The frozen preparations have caused no harmful effects in the subjects, are free from irritant properties, and are not urticariogenic. PMID:13126823

    In Japan, air pollution due to nitrogen oxides (NOx) and particulate matter (PM) has been gradually reduced since control measures based on the Automobile NOx/PM law were enforced beginning in 2001. The effects of decrease in air pollutants due to the control measures during the past decade on the prevalence of respiratory and allergic disorders such as asthma in children were evaluated. Using data of 618,973 children collected in 28 regions of Japan from 1997 to 2009, we evaluated whether reductions in the concentrations of nitrogen dioxide (NO2) and suspended particulate matter (SPM) contribute to the decrease in the prevalence of asthma, wheezing, bronchitis, allergic rhinitis, and atopic dermatitis by multiple linear regression analysis, including adjustments for related factors. The annual rates of decrease in air pollution in the PM-law-enforced areas were 2.0 and 2.5 times higher for NO2 and SPM, respectively, compared with those in the non-enforced areas. The prevalence of asthma decreased significantly at -0.073% per year in the areas in which measures based on the Automobile NOx/PM law were taken but not in area where such measures were not applied. Multiple linear regression analysis showed a reduction in the ambient air pollution was significantly associated with a reduction in the prevalence of asthma, with a rate of 0.118% [95% confidence interval (CI): 0.012-0.225] per 1 ppb for NO2, and 0.050% [95% CI: 0.020-0.080] per 1 μg/m(3) for SPM. An increase in the ambient air pollution was associated with an increase in the prevalence of atopic dermatitis of 0.390% [95% CI: 0.107-0.673] per 1 ppb for NO2, 0.141% [95% CI: 0.058-0.224] per 1 μg/m(3) for SPM. The changes in the prevalence of wheezing and allergic rhinitis were not significantly correlated with changes in air pollutant concentrations. The enforcement of measures to control automobile emissions based on the Automobile NOx/PM law was shown to have reduced air pollution and contributed to

    Trichotillomania is currently classified as an impulse control disorder not otherwise classified, whereas body-focused behaviors other than hair-pulling may be diagnosed as stereotypic movement disorder. A number of disorders characterized by repetitive, body-focused behaviors (eg, skin-picking) are prevalent and disabling and may have phenomenological and psychobiological overlap. Such disorders deserve greater recognition in the official nosology, and there would seem to be clinical utility in classifying them in the same diagnostic category.

    Allergic sensitisation is poorly documented in infants. This study aims to provide new insights into allergic sensitisation patterns and related factors in infancy. This study concerns 1860 infants involved in the Pollution and Asthma Risk: an Infant Study (PARIS) population-based birth cohort who had a standardised health examination when 18 months old, from 2004 to 2008. Sensitisation was assessed by measurements of serum specific IgE to 12 food and 4 inhalant allergens and defined by IgE≥0.35kUA/L. Information regarding lifestyle and environment were obtained from questionnaires prospectively administered. Prevalence of allergic sensitisation to any allergen, to food allergens, and to aeroallergens was 13.8%, 12.3%, and 2.3%, respectively. Multiple sensitisation (to at least two allergens) concerned 6.2% of toddlers. Intrinsic factors such as male gender, family history of allergy, and high birth weight increased the risk of food allergen sensitisation and multiple sensitisation. Caesarean section was also positively associated with multiple sensitisation. Day-care attendance was negatively related to food allergen, aeroallergen, and multiple sensitisation. A cat entering the baby's room in early life was strongly associated with aeroallergen sensitisation (ORa 3.21, 95%CI: 1.29-8.01). An introduction of meat in infant's diet after 6 months of age was negatively related to food allergen sensitisation (ORa 0.46, 95%CI: 0.24-0.91). Our results suggest that intrinsic factors and indicators of exposure to microorganisms such as caesarean section and day-care attendance may be associated with inhalant as well as food allergen sensitisation in infancy. For example, male gender, family history of allergy, high birth weight, and caesarean section could be positively related whereas day-care attendance could be negatively related to both aeroallergen and food allergen sensitisation. Conversely, early life exposure to inhalant allergens or food allergens may be

    Nitrogen dioxide (NO2), a surrogate measure of traffic-related air pollution (TRAP), has been associated with incident childhood asthma. Timing of exposure and atopic status may be important effect modifiers. We collected cross-sectional data on asthma outcomes from Toronto school children aged 5-9years in 2006. Lifetime home, school and daycare addresses were obtained to derive birth and cumulative NO2 exposures for a nested case-control subset of 1497 children. Presence of other allergic disease (a proxy for atopy) was defined as self-report of one or more of doctor-diagnosed rhinitis, eczema, or food allergy. Generalized estimating equations were used to adjust for potential confounders, and examine hypothesized effect modifiers while accounting for clustering by school. In children with other allergic disease, birth, cumulative and 2006 NO2 were associated with lifetime asthma (OR 1.46, 95% CI 1.08-1.98; 1.37, 95% CI 1.00-1.86; and 1.60, 95% CI 1.09-2.36 respectively per interquartile range increase) and wheeze (OR 1.44, 95% CI 1.10-1.89; 1.31, 95% CI 1.02-1.67; and 1.60, 95% CI 1.16-2.21). No or weaker effects were seen in those without allergic disease, and effect modification was amplified when a more restrictive algorithm was used to define other allergic disease (at least 2 of doctor diagnosed allergic rhinitis, eczema or food allergy). The effects of modest NO2 levels on childhood asthma were modified by the presence of other allergic disease, suggesting a probable role for allergic sensitization in the pathogenesis of TRAP initiated asthma.

    Wild-type varicella zoster infection (WTVZV) up to 8 yr of age has been shown to protect against atopic dermatitis (AD) and asthma. We sought to determine whether WTVZV in childhood protects against atopic disorders, allergic sensitization or decreases serum Immunoglobulin E (IgE) levels. We conducted a retrospective, practice-based study of outpatient pediatric practices in NY. One hundred children with WTVZV up to 8 yr of age and 323 children who received varicella vaccine (VV) were randomly selected. WTVZV up to 8 yr of age is associated with decreased odds of subsequent asthma (exact logistic regression; OR = 0.12, 95% CI = 0.03-0.57, p = 0.003), allergic rhinoconjunctivitis (OR = 0.16, 95% CI = 0.05-0.49, p = 0.0003), and AD (OR = 0.57, 95% CI = 0.33-0.96, p = 0.02), but not food allergies (p = 0.78); decreased total serum IgE levels [mixed linear model, LSM (95% CI): 129.09 (33.22-501.63) vs. 334.21 (102.38-1091.04) IU/ml; p = 0.02] remained significant at all time intervals after WTVZV (<5, 5-10, and >10) compared with VV (p = 0.003-0.03). WTVZV was associated with decreased allergic sensitization (logistic regression, OR = 0.11, 95% CI = 0.03-0.38, p = 0.0004). WTVZV is also associated with persistently decreased numbers of peripheral blood lymphocytes (p < 0.0001) for up to 12 yr (p = 0.0003-0.047), monocytes (p = 0.002) for up to 16 yr (p < 0.001) and basophils at ages 4-6, 10-12, and 14-16 (p < 0.03). WTVZV up to 8 yr of age protects against atopic disorders, which is likely mediated by suppression of IgE production and allergic sensitization, as well as altered leukocyte distributions. © 2011 John Wiley & Sons A/S.

    Venom immunotherapy (VIT) is effective in preventing anaphylactic reactions after insect stings. The effect of VIT on health-related quality of life (HRQL) was studied to evaluate whether this treatment is of importance to patients. We compared HRQL outcomes measured with a disease-specific instrument (Vespid Allergy Quality-of-Life Questionnaire [VQLQ]) in patients allergic to yellow jacket venom treated with VIT or with an adrenalin self-administration device (EpiPen) in an open-label, randomized, controlled trial. Consenting patients were block randomized to either VIT or EpiPen. Patients received uniform, standardized information, which specified the risk of their condition and the risks and benefits of both treatment options. HRQL measures took place before and after 1 year of treatment with VIT or EpiPen. Seventy-four patients agreed to be randomized, of whom 36 received VIT and 38 an EpiPen. The mean change in VQLQ score in the group randomized to VIT was 1.07 (95% CI, 0.68-1.46), and this improvement was statistically significant (P <.0001) compared with that seen in the group randomized to the EpiPen, in which this change was -0.43 (95% CI, -0.71 to -0.16). These differences were seen in both men and women, persons with more or less general anxiety, and those stung recently and those stung more than a year before their outpatient department visit. The overall proportion of patients receiving benefit from VIT is 0.72, generating a number needed to treat of 1.4. VIT results in a clinically important improvement in HRQL in patients allergic to yellow jacket venom in all subgroups studied. Of every 3 patients treated with VIT, 2 patients experience an important improvement in their quality of life.

    During a 7-year period, 56 patients were referred to the Department of General Pathology and Internal Medicine and the Department of Dental Materials, University of Amsterdam, to determine whether contact allergic reactions to dental materials were the cause of their complaints. On the first consultation with the patient a detailed history focusing on the complaints themselves, general medical history, and special clinical history of allergic skin reaction was obtained. Oral examinations were performed, and all patients were referred to the allergy clinic at the department of dermatology for skin tests. There was a strong female predominance in the referred group. Most of the patients with allergic contact stomatitis mentioned a burning sensation in the mouth. In only 16 of the 56 patients could the diagnosis of allergic contact stomatitis be established. From this study it can also be concluded that the combination of a positive allergic history and positive allergic skin reactions with or without visible oral signs are important for the diagnosis of allergic contact stomatitis.

    An immune hypersensitivity disorder called allergy is caused by diverse allergens entering the body via skin contact, injection, ingestion, and/or inhalation. These allergic responses may develop into allergic disorders, including inflammations such as atopic dermatitis, asthma, anaphylaxis, food allergies, and allergic rhinitis. Several drugs have been developed to treat these allergic disorders; however, long-term intake of these drugs could have adverse effects. As an alternative to these medicines, food and natural materials that ameliorate allergic disorder symptoms without producing any side effects can be consumed. Food and natural materials can effectively regulate successive allergic responses in an allergic chain-reaction mechanism in the following ways: [1] Inhibition of allergen permeation via paracellular diffusion into epithelial cells, [2] suppression of type 2 T-helper (Th) cell-related cytokine production by regulating Th1/Th2 balance, [3] inhibition of pathogenic effector CD4(+) T cell differentiation by inducing regulatory T cells (Treg), and [4] inhibition of degranulation in mast cells. The immunomodulatory effects of food and natural materials on each target mechanism were scientifically verified and shown to alleviate allergic disorder symptoms. Furthermore, consumption of certain food and natural materials such as fenugreek, skullcap, chitin/chitosan, and cheonggukjang as anti-allergics have merits such as safety (no adverse side effects), multiple suppressive effects (as a mixture would contain various components that are active against allergic responses), and ease of consumption when required. These merits and anti-allergic properties of food and natural materials help control various allergic disorders.

    Singh, A; Holvoet, S; Mercenier, A

    2011-10-01

    Allergic disorders encompass skin, food and respiratory allergies. Sensitization to a normally harmless allergen results in the immune system being biased to a predominant T-helper type 2 response. Re-exposure to the same allergen leads to a robust secretion of allergy-related mediators that eventually triggers symptoms. Our understanding of these disorders has enabled the search of therapeutic approaches that can either modulate the sensitization process or impact on allergic mediators, thus helping manage allergic symptoms. Polyphenols are one such class of compounds that are found in foods and plant sources and have been investigated for their anti-allergic effect in different disease models and in human clinical trials. Their anti-inflammatory profile is known to impact on the recruitment of immune cells to the skin and in preventing the development of secondary infections following disruption of the skin barrier. The interaction of polyphenols with proteins can modulate the process of allergic sensitization and their direct effect on allergic effector cells such as mast cells inhibit mediator release, resulting in the alleviation of symptoms. In addition, their endogenous anti-oxidant ability limits the extent of cellular injury from free radicals during the allergic insult. Overall, polyphenols hold promise as anti-allergy agents capable of influencing multiple biological pathways and immune cell functions in the allergic immune response and deserve further investigation. The objective of the current review is to summarize the key findings and progress made in studying polyphenols as anti-allergic ingredients. Special emphasis is placed in this review to highlight key physiological, cellular and signalling pathways implicated in the mechanism of action of different polyphenols in the context of allergic disorders and their manifestations.

    To date, there are sparse data on epinephrine treatment for food-related anaphylaxis in adults. We sought to establish the frequency of more than one epinephrine treatment for adult patients who present with food-related anaphylaxis to the emergency department (ED). We performed a chart review, at two academic centers, of all adults presenting to the ED for food allergy (ICD9CM codes 693.1, 995.0, 995.1, 995.3, 995.7, 995.60-995.69, 558.3, 692.5, and 708.X) between January 1, 2001 and December 31, 2006. We focused on causative foods; treatments, including the number of epinephrine treatments given before and during the ED visit; and disposition. Through random sampling and appropriate weighting, the 486 reviewed cases represented a study cohort of 1286 patients. The median age was 36 years and the cohort was 62% women. Shellfish (23%), peanuts (12%), tree nuts (14%), and fish (14%) provoked the allergic reaction most commonly. Most patients (62%; 95% confidence interval [CI], 57-68%) met criteria for food-related anaphylaxis. In the ED, anaphylaxis patients received epinephrine (18%), antihistamines (91%), corticosteroids (81%), and inhaled albuterol (19%). Overall, 17% (95% CI, 9-25%) of patients with food-related anaphylaxis given epinephrine received >1 dose over the course of their reaction. Among anaphylaxis patients admitted to the hospital, only 10% included anaphylaxis in the discharge diagnosis. At ED discharge (82% of patients), 18% were referred to an allergist and 39% were prescribed self-injectable epinephrine. Among ED patients with food-related anaphylaxis treated with epinephrine, 17% were given >1 dose. This study supports the recommendation that patients at risk for food-related anaphylaxis should carry 2 doses of epinephrine.

    The eosinophil is a multifunctional granulocyte best known for providing host defense against parasites. Paradoxically, eosinophils are also implicated in the pathogenesis of allergic inflammation, asthma, and hypereosinophilic syndromes. Emerging evidence also supports the potential for harnessing the cytotoxic power of eosinophils and redirecting it to kill solid tumors. Central to eosinophil physiology is interleukin-5 (IL-5) and its receptor (IL-5R) which is composed of a ligand-specific alpha chain (IL-5Rα) and the common beta chain (βc). Eosinophil activation can lead to their degranulation, resulting in rapid release of an arsenal of tissue-destructive proinflammatory mediators and cytotoxic proteins that can be both beneficial and detrimental to the host. This review discusses eosinophil immunobiology and therapeutic strategies for targeting of IL-5 and IL-5R, as well as the potential for harnessing eosinophil cytotoxicity as a tumoricide.

    Twin and family studies support a significant genetic contribution to obsessive-compulsive disorder (OCD) and related disorders, such as chronic tic disorders, trichotillomania, skin-picking disorder, body dysmorphic disorder, and hoarding disorder. Recently, population-based studies and novel laboratory-based methods have confirmed substantial heritability in OCD. Genome-wide association studies and candidate gene association studies have provided information on specific gene variations that may be involved in the pathobiology of OCD, though a substantial portion of the genetic risk architecture remains unknown.

    T helper (Th)17 cells may play a role in allergic asthma. This study assessed the effect of allergen inhalation challenge on circulating Th17 cells and related cytokines in allergic asthmatics. Peripheral blood mononuclear cells were collected from 16 atopic asthmatics before and 24 h after allergen challenge, as well as from 10 atopic nonasthmatics and 10 normal controls. Cells were stained for Th17 cytokines and their receptors (IL-17A, IL-17F, IL-21, IL-22, IL-17R, and IL-23R) using flow cytometry. Cytokine concentrations from cell culture supernatants were quantified using a multiplex assay for IL-17A, IL-17F, IL-21, IL-22, and IL-23. At baseline, asthmatics had a higher percentage of circulating Th17 cells (1.2 ± 0.5%) compared to normal controls (0.9 ± 0.66%, p < 0.001) but not compared to atopic nonasthmatics (1.13 ± 0.5%). There was a significant increase in Th17 cells in asthmatics after allergen challenge to 1.55 ± 0.4% (p < 0.05) and a trend toward significance in IL-17R expression from 3.4 ± 4.3 to 6.86 ± 6.84% after allergen challenge (p = 0.06). There was also a significant reduction in IL-21-positive cells following allergen challenge from 3.46 ± 1.85 to 2.33 ± 1.37% (p < 0.001). There were no significant differences in IL-17F, IL-22 and IL-23R expression. The concentration of IL-17A in culture supernatant was significantly higher in asthmatics compared to normal controls and IL-17A significantly increased 24 h after allergen challenge. The increase of Th17 cells and IL-17A in atopic asthma after allergen inhalation challenge suggests a possible role for Th17 in allergen-induced airway responses. © 2014 S. Karger AG, Basel.

The presence of an aggressive disorder generally increased the risk of suicide attempts and mortality, with this effect (when examined) usually existing independent of other psychopathology. However, this may not be the case for antisocial personality disorder. Furthermore, with the exception of intermittent explosive disorder, the extant research suggests severity of aggression was associated with suicide attempt risk in aggression-related disorders. Future research is needed to better understand what mechanisms may influence the suicide-aggression relationship. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Allergen specific immunotherapy (ASIT) and environmental control are the only etiologic treatments of allergic rhino-conjunctivitis, asthma and atopic dermatitis. The clinical benefit of ASIT relies on the selection of the patients and the identification and administration of the allergen, or allergens. Different routes of administration have been investigated, including subcutaneous, intradermal, epicutaneous, sublingual, inhaled, or intra-lymphatic. While subcutaneous and sublingual allergen specific immunotherapy may require from 3 to 5 years of treatment, clinical efficacy with intra-lymphatic treatment can be achieved after 3 injections. The most severe side effect of ASIT is anaphylaxis. Novel approaches are being investigated to reduce the allergenicity of immunotherapy vaccines, maintaining immunogenicity. Peptide immunotherapy has been directed mostly against autoimmune diseases, but the use of synthetic peptides for ASIT is a promising field in basic science, applied immunology and in clinical development. Short synthetic peptides bear allergen-specific CD4 T-cell epitopes which induce tolerance by stimulating regulatory (Treg) and Th1 cells. In the present patent review, we describe new trends in allergen immunotherapy using peptides, which, from a clinical point of view, are promising.

    Among the major allergic pulmonary disorders are bronchial asthma, extrinsic allergic alveolitis, allergic aspergillosis and berylliosis. Asthma is diagnosed on the basis of clinical symptoms (wheezing, respiratory distress, tight chest, coughing) and lung function tests possibly supplemented by allergic and provocative testing. Asthma treatment is differentiated into long-term medication and as-required medication. Specific immunotherapy is considered the sole causal therapy. Extrinsic allergic alveolitis is work- or hobby-related (farmer's/cheese worker's/bird-fancier's lung) and manifests as diffuse pneumonitis with dyspnea, coughing and fever. For the diagnosis, the antigen provocative test in particular plays a major role. In the main, treatment comprises strict avoidance of allergens. The diagnosis of allergic pulmonary aspergillosis is based on the history, clinical findings, skin tests, serology and radiography. Treatment is stage-related by means of immunosuppressive agents. In terms of radiographic and pulmonary function findings, berylliosis is similar to sarcoidosis. Here, too, immunosuppressive agents are to the fore.

    The contributing role of indoor air pollution to the development of allergic disease has become increasingly evident in public health problems. It has been reported that extensive communication exists between neurons and immune cells, and neurotrophins are molecules potentially responsible for regulating and controlling this neuroimmune crosstalk. The adverse effects of volatile organic compounds which are main indoor pollutants on induction or augmentation of neuroimmune interaction have not been fully characterized yet. To investigate the effects of low-level toluene inhalation on the airway inflammatory responses, male C3H mice were exposed to filtered air (control), 9 ppm, and 90 ppm toluene for 30 min by nose-only inhalation on Days 0, 1, 2, 7, 14, 21, and 28. Some groups of mice were injected with ovalbumin intraperitoneally before starting exposure schedule and these mice were then challenged with aerosolized ovalbumin as booster dose. For analysis of airway inflammation, bronchoalveolar lavage (BAL) fluid were collected to determine inflammatory cell influx and lung tissue and blood samples were collected to determine cytokine and neurotrophin mRNA and protein expressions and plasma antibody titers using real-time RT-PCR and ELISA methods respectively. Exposure of the ovalbumin-immunized mice to low-level toluene resulted in (1) increased inflammatory cells infiltration in BAL fluid; (2) increased IL-5 mRNA, decreased nerve growth factor receptor tropomyosin-related kinase A and brain-derived neurotrophic factor mRNAs in lung; and (3) increased IgE and IgG{sub 1} antibodies and nerve growth factor content in the plasma. These findings suggest that low-level toluene exposure aggravates the airway inflammatory responses in ovalbumin-immunized mice by modulating neuroimmune crosstalk.

    To use food-specific IgG antibody detection to explore its application in the allergy dermatoses. 181 patients were included from January 2014 to September 2014. Fourteen food-specific IgG antibodies were detected by ELISA. The positive rates of IgG antibody of the patient group and the healthy group were significantly different. The positive rates of IgG antibody of egg, milk, shrimp and crab took a large proportion in three groups of patients with three kinds of allergy dermatoses of urticaria, eczema and allergic dermatitis, the proportion of which was respectively 70.2%, 77.8% and 71.7%. There was mild and moderate intolerance of food in the allergic dermatitis group while there was no distribution difference of food intolerance in urticaria group and eczema group. Among urticaria and allergic dermatitis patients with positive antibody, the positive rate of children was significantly higher than that of adults while there was no significant difference between children and adults among eczema patients with positive antibody. Allergy dermatoses are closely related to food-specific IgG antibody and the allergy dermatoses patients have a high incidence rate of food intolerance; detecting IgG antibody in patients is of great significance for the diagnosis and treatment of allergy dermatoses.

    Synopsis Twin and family studies support a significant genetic contribution to obsessive-compulsive disorder (OCD) and related disorders such as chronic tic disorders, trichotillomania, skin picking disorder, body dysmorphic disorder, and hoarding disorder. Recently, population-based studies and novel laboratory-based methods have confirmed substantial heritability in OCD. Genome-wide association studies and candidate gene association studies have provided information on specific genes that may be involved in the pathobiology of OCD and also of related disorders, particularly chronic tic disorders, though these genes each contribute only a small portion of the total genetic risk and a substantial portion of the specific genetic risk profile in OCD is still unknown. Nevertheless, there are some examples of genes for which perturbations produce OCD-like phenotypes in animal model systems, allowing a laboratory platform for investigating the pathobiology of --- and new treatments for --- OCD and related disorders. Future work promises to continue to clarify the specific genes involved in risk for OCD as well as their interaction with environmental variables. PMID:25150565

    Sleep disorder is associated with the lifestyle-related diseases including obesity, insulin resistance and atherosclerosis. Adipose tissue functions as an endocrine organ by producing bioactive secretory proteins, also known as adipokines, that can directly act on nearby or remote organs. Recently, the associations between these adipokines and sleep disorders such as obstructive sleep apnea have been reported. In this review, we focus on the relationship between sleep disorder and lifestyle-related diseases.

    Familiarity with the diagnosis and management of allergic rhinitis is important for physicians concerned with the nasal airway. Allergic rhinitis is a common and manageable condition that may cause persistent or intermittent symptoms that vary as to duration and severity. Allergic rhinitis impairs quality of life, sleep, school performance, and productivity on a scale that compares with other chronic diseases. Diagnosis is primarily clinical, but supported by allergy testing. Therapeutic options for allergic rhinitis include pharmacotherapy, environmental control, and immunotherapy. More recently, a role for sublingual immunotherapy and turbinate reduction has been reported. Copyright © 2012 Elsevier Inc. All rights reserved.

    Allergic contact dermatitis is one of the most important dermatologic disorders worldwide - it can cause significant morbidity and decreased quality of life, as well as having major economic implications and loss of vocational productivity. Patch testing is the most important discovery in allergic contact dermatitis and the best diagnostic modality to date; the thin-layer rapid- use epicutaneous (TRUE) test is a more recent patch test development which has improved the convenience and feasibility of the test. The future of allergic contact dermatitis is bright as we continue to learn more about the science of the disorder, as well as ways to improve diagnosis and patient care. Furthermore, it is important to remember, in this global age, that cooperation between health care providers worldwide is essential.

    Working conditions in the construction industry have improved in many industrialized countries, but heavy physical work with recurrent exposure to chemical agents, dust, and climatic influences still represents considerable risk for construction workers and may affect their health. The aim of this review is to analyze available data of the literature on allergy-related respiratory and skin disorders with emphasis on a preventive appraisal in order to produce statements and recommendations based on research evidence. The most common agents involved in the construction industry as a cause of occupational asthma (OA) in industrialized countries are isocyanates, wood dust, resins, glues, cobalt, and chromium. Allergic contact dermatitis (ACD) is an immunologic cell-mediated response to a sensitizing agent and the most common sensitizing agents associated with construction workers are epoxy resins, thiurams and thiazoles, and chromates. Medical surveillance must consider individual risk factors such as differences in individual susceptibility and sensitization to agents at workplace. Once work-related disorder is confirmed, adequate fitness for work should be assessed for the worker impaired by health condition. A reliable diagnosis of an index case is a sentinel event that may reveal risks for workers with similar exposure, leading to a revised risk assessment at the workplace that should reduce the risk and prevent further cases.

    Emerging evidence questions current recommendations on the timing of infant feeding for the prevention of childhood allergies. The evidence for asthma is inconclusive. We sought to investigate the associations between the duration of breast-feeding and timing of introduction of complementary foods and the development of asthma and allergies by the age of 5 years. Data were analyzed for 3781 consecutively born children. The dietary exposures were categorized into thirds and analyzed as time-dependent variables. Asthma, allergic rhinitis, and atopic eczema end points were assessed by using the International Study of Asthma and Allergies in Childhood questionnaire, whereas IgE antibodies were analyzed from serum samples at the age of 5 years. Cox proportional hazard and logistic regressions were used for the analyses. The median duration of exclusive and total breast-feeding was 1.4 months (interquartile range, 0.2-3.5 months) and 7.0 months (interquartile range, 4.0-11.0 months), respectively. Total breast-feeding of 9.5 months or less was associated with an increased risk of nonatopic asthma. Introduction of wheat, rye, oats, or barley at 5 to 5.5 months was inversely associated with asthma and allergic rhinitis, whereas introduction of other cereals at less than 4.5 months increased the risk of atopic eczema. Introduction of egg at 11 months or less was inversely associated with asthma, allergic rhinitis, and atopic sensitization, whereas introduction of fish at 9 months or less was inversely associated with allergic rhinitis and atopic sensitization. Early introduction of wheat, rye, oats, and barley cereals; fish; and egg (respective to the timing of introduction of each food) seems to decrease the risk of asthma, allergic rhinitis, and atopic sensitization in childhood. Longer duration of total breast-feeding, rather than its exclusivity, was protective against the development of nonatopic but not atopic asthma, suggesting a potential differing effect of breast

    The thalassemias, sickle cell disease, and other hemoglobinopathies represent a major group of inherited disorders of hemoglobin synthesis. The abnormal hemoglobins were reviewed in the July 2006 issue of Baylor University Medical Center Proceedings. Because of immigration patterns and population flow, these disorders are becoming increasingly more prevalent in the USA. In this article, the clinical aspects of the more common thalassemia syndromes are reviewed. For most symptomatic patients with thalassemia, there is no definite cure; only supportive management of the anemia is possible. A very limited number of patients with thalassemia may be cured by bone marrow transplantation from HLA-identical donors. Other tentative approaches to management include stimulation of fetal hemoglobin synthesis and attempts at somatic cell gene therapy. Prevention of disease transmission by carrier screening programs along with prenatal diagnosis remain of paramount importance in the reduction of these diseases worldwide. PMID:17256039

    Workplace-related anxieties are often connected with sick leave. There are no established instruments which allow to assess this phenomenologically heterogeneous group of disorders. One hundred and thirty-two psychosomatic inpatients were interviewed with a standardized diagnostic interview in respect to mental illnesses, especially primary anxiety disorders, and in addition in respect to different work-related anxiety disorders. Seventy-one percent of women and 54% of men complained about work-related anxiety. 20.5% of participants are suffering from work-related panic, 58% from work-related phobia, 34.1% from work-related social phobia, 39.4% from work-related generalized anxiety, and 1.5% from work-related PTSD. There is a moderate relation between mental disorders or primary anxiety disorders and work-related anxiety. Fourteen percent of the participants did only suffer from workplace-related anxiety and did not report any other anxiety disorder outside the workplace situation. There are various types of workplace-related anxieties. They are partly independent clinical phenomena deserving special diagnostic and therapeutic attention.

    Associations between traffic-related air pollution (TRAP) and allergic rhinitis remain inconsistent, possibly because of unexplored gene-environment interactions. In a pooled analysis of 6 birth cohorts (Ntotal = 15,299), we examined whether TRAP and genetic polymorphisms related to inflammation and oxidative stress predict allergic rhinitis and sensitization. Allergic rhinitis was defined with a doctor diagnosis or reported symptoms at age 7 or 8 years. Associations between nitrogen dioxide, particulate matter 2.5 (PM2.5) mass, PM2.5 absorbance, and ozone, estimated for each child at the year of birth, and single nucleotide polymorphisms within the GSTP1, TNF, TLR2, or TLR4 genes with allergic rhinitis and aeroallergen sensitization were examined with logistic regression. Models were stratified by genotype and interaction terms tested for gene-environment associations. Point estimates for associations between nitrogen dioxide, PM2.5 mass, and PM2.5 absorbance with allergic rhinitis were elevated, but only that for PM2.5 mass was statistically significant (1.37 [1.01, 1.86] per 5 μg/m(3)). This result was not robust to single-cohort exclusions. Carriers of at least 1 minor rs1800629 (TNF) or rs1927911 (TLR4) allele were consistently at an increased risk of developing allergic rhinitis (1.19 [1.00, 1.41] and 1.24 [1.01, 1.53], respectively), regardless of TRAP exposure. No evidence of gene-environment interactions was observed. The generally null effect of TRAP on allergic rhinitis and aeroallergen sensitization was not modified by the studied variants in the GSTP1, TNF, TLR2, or TLR4 genes. Children carrying a minor rs1800629 (TNF) or rs1927911 (TLR4) allele may be at a higher risk of allergic rhinitis. Copyright © 2013 American Academy of Allergy, Asthma & Immunology.

    2015-01-01

    Neglect is a neurologic disorder, typically associated with lesions of the right hemisphere, in which patients are biased towards their ipsilesional - usually right - side of space while awareness for their contralesional - usually left - side is reduced or absent. Neglect is a multimodal disorder that often includes deficits in the auditory domain. Classically, auditory extinction, in which left-sided sounds that are correctly perceived in isolation are not detected in the presence of synchronous right-sided stimulation, has been considered the primary sign of auditory neglect. However, auditory extinction can also be observed after unilateral auditory cortex lesions and is thus not specific for neglect. Recent research has shown that patients with neglect are also impaired in maintaining sustained attention, on both sides, a fact that is reflected by an impairment of auditory target detection in continuous stimulation conditions. Perhaps the most impressive auditory symptom in full-blown neglect is alloacusis, in which patients mislocalize left-sided sound sources to their right, although even patients with less severe neglect still often show disturbance of auditory spatial perception, most commonly a lateralization bias towards the right. We discuss how these various disorders may be explained by a single model of neglect and review emerging interventions for patient rehabilitation.

    The past 15 years of allergic disease research have produced extraordinary improvements in our understanding of the pathogenesis of airway allergic diseases such as asthma. Whereas it was previously viewed as largely an immunoglobulin E-mediated process, the gradual recognition that T cells, especially Type 2 T helper (Th2) cells and Th17 cells, play a major role in asthma and related afflictions has inspired clinical trials targeting cytokine-based inflammatory pathways that show great promise. What has yet to be clarified about the pathogenesis of allergic inflammatory disorders, however, are the fundamental initiating factors, both exogenous and endogenous, that drive and sustain B- and T-cell responses that underlie the expression of chronic disease. Here we review how proteinases derived from diverse sources drive allergic responses. A central discovery supporting the proteinase hypothesis of allergic disease pathophysiology is the role played by airway fibrinogen, which in part appears to serve as a sensor of unregulated proteinase activity and which, when cleaved, both participates in a novel allergic signaling pathway through Toll-like receptor 4 and forms fibrin clots that contribute to airway obstruction. Unresolved at present is the ultimate source of airway allergenic proteinases. From among many potential candidates, perhaps the most intriguing is the possibility such enzymes derive from airway fungi. Together, these new findings expand both our knowledge of allergic disease pathophysiology and options for therapeutic intervention. PMID:25525732

    2011-10-01

    NKT cells are a heterogeneous subset of specialized, self-reactive T cells, with innate and adaptive immune properties, which allow them to bridge innate and adaptive immunity and profoundly influence autoimmune and malignant disease outcomes. NKT cells mediate these activities through their ability to rapidly express pro- and anti-inflammatory cytokines that influence the type and magnitude of the immune response. Not only do NKT cells regulate the functions of other cell types, but experimental evidence has found NKT cell subsets can modulate the functions of other NKT subsets. Depending on underlying mechanisms, NKT cells can inhibit or exacerbate autoimmunity and malignancy, making them potential targets for disease intervention. NKT cells can respond to foreign and endogenous antigenic glycolipid signals that are expressed during pathogenic invasion or ongoing inflammation, respectively, allowing them to rapidly react to and influence a broad array of diseases. In this article we review the unique development and activation pathways of NKT cells and focus on how these attributes augment or exacerbate autoimmune disorders and malignancy. We also examine the growing evidence that NKT cells are involved in liver inflammatory conditions that can contribute to the development of malignancy.

    The incidence of sleep-related breathing disorders is correlated with lower and upper airway inflammatory diseases, such as asthma and allergic rhinitis. We hypothesized that corticosteroids treatment would lead to a greater reduction in disease severity in obstructive sleep apnoea syndrome (OSAS) patients with concomitant allergic rhinitis vs. non-allergic OSAS patients by reducing the level of inflammation in upper airway tissues. This study was performed to determine whether treatment with intranasal corticosteroids could reduce upper airway inflammation and improve sleep parameters in obstructive sleep apnoea syndrome patients with or without concomitant allergic rhinitis. Obstructive sleep apnoea syndrome patients with (n = 34) or without (n = 21) documented allergic rhinitis voluntarily enrolled in the study and were assessed at baseline and after corticosteroids treatment for 10-12 weeks. Sleep studies were performed and biopsies were obtained from the inferior turbinate, nasopharynx, and uvula. The apnoea-hypopnoea index, sleep quality, and level of daytime alertness were determined, and immunocytochemistry was used to phenotype tissue inflammation. Standard sleep indices improved following treatment in the entire cohort of obstructive sleep apnoea syndrome patients, with greater improvement seen in the allergic rhinitis group. Allergic rhinitis patients demonstrated significantly improved O2 saturation and a lower supine apnoea-hypopnoea index score after corticosteroid treatment; similar improvements were not seen in the non-allergic rhinitis group. Eosinophilia was detected at all three sites in the allergic rhinitis group, but not in the non-allergic rhinitis group. Following treatment, fewer eosinophils and CD4 lymphocytes were documented at all three biopsy sites in the allergic group; the reduction in inflammation was less apparent in the non-allergic rhinitis group. This study has provided important molecular and clinical evidence regarding the

    Contact (allergic) dermatitis is a skin disorder related to natural exposure to various allergens. Systemic contact dermatitis (SCD) describes a cutaneous eruption in response to systemic exposure to an allergen. The exact pathologic mechanism remains uncertain. Herein we describe a 36-year-old woman with symmetric systemic allergic contact dermatitis, unresponsive to conventional treatment, associated with dental alloy-contact hypersensitivity. We did skin patch testing and the blood lymphocyte transformation test (LTT) from the dental allergen series to assess contact allergy to restorative dental materials. On patch testing, positive allergic contact dermatitis reactions to metals occurred (nickel, potassium dichromate, and gold). Nickel hypersensitivity was confirmed by LTT, which also revealed silver-amalgam sensitization. Our case report highlights the need to consider adverse reactions to base-metal dental alloys in the differential diagnosis of cases of systemic allergic contact dermatitis.

    Peripheral dyslexias are the result of impairment to processes that convert letters on the page into an abstract orthographic representation. Many aspects of these disorders are difficult to understand in depth. Invariably, there is evidence that some type of word-level perception occurs rapidly in many patients with LBL reading or neglect dyslexia, yet apparently contradictory evidence indicates that part of the word has been misperceived or that the letters must be analyzed laboriously for conscious identification to occur. Current theories attempt to synthesize these different aspects of the patients' performance, but their development is at an early stage. Questions remain also about the domain specificity of the perceptual impairment in LBL reading and about the nature of spatial attention and spatial frames in neglect dyslexia and other forms of attentional disorder. Current understanding of central dyslexias has perhaps advanced further. Well-developed computational models exist of these dyslexias, as do plausible experimental techniques for revealing the activity of semantic and non-semantic routes in normal readers. Nevertheless, the difficult issue of domain specificity arises again with respect to some of the mechanisms invoked, and in this regard, central and peripheral dyslexias continue to pose the same challenge.

    Activation of mast cells through FcεRI plays an important role in acute allergic reactions. However, little is known about the function of mast cells in patients with chronic allergic inflammation or the effect of repeated FcεRI triggering occurring in such responses. We aimed to identify changes in mast cell function after repeated FcεRI triggering and to correlate these changes to chronic allergic responses in tissue. Human cord blood-derived mast cells were treated for 2 weeks with anti-IgE. The function of naive or treated mast cells was analyzed by means of RNA sequencing, quantitative RT-PCR, flow cytometry, and functional assays. Protein secretion was measured with ELISAs and multiplex assays. We observed several changes in mast cell function after repeated anti-IgE triggering. Although the acute response was dampened, we identified 289 genes significantly upregulated after repeated anti-IgE. Most of these genes (84%) were not upregulated after a single anti-IgE stimulus, indicating a significantly different response mode characterized by increased antigen presentation, response to bacteria, and chemotaxis. Changes in mast cell function were related to changes in expression of the transcription factors RXRA and BATF and others. Importantly, we found a substantial overlap between genes upregulated after repeated anti-IgE triggering and genes upregulated in tissue from patients with chronic allergy, in particular those of patients with chronic rhinosinusitis. Our study provides evidence for intrinsic modulation of mast cell function on repeated FcεRI-mediated activation. The overlap with gene expression in tissues is suggestive of a direct link between repeated IgE-mediated activation of mast cells and chronic allergy.

  15. Nasal-Ocular Reflexes and Their Role in the Management of Allergic Rhinoconjunctivitis With Intranasal Steroids

    PubMed Central

    2011-01-01

    Allergic rhinitis is a common disorder and involves the reaction to environmental allergens with resultant nasal and eye symptoms. The pathophysiologic mechanisms of the eye symptoms in allergic conjunctivitis include a direct effect on the eye by deposited allergen and indirect effects related to the deposition of allergen in the nasal mucosa. One of these proposed mechanisms is the existence of a nasal-ocular reflex whereby the nasal allergic reaction leads to an afferent reflex response, the efferent limb of which results in eye symptoms. Among the treatments available for allergic rhinitis, intranasal steroids are most efficacious for nasal symptoms and have also shown sizeable efficacy related to eye symptoms. We speculated that the effect of intranasal steroids on eye symptoms in allergic rhinitis was related to their inhibition of the nasal-ocular reflex and present data previously generated from our laboratory to support this assumption in a nasal challenge model.

    The hereditary porphyrias comprise a group of eight metabolic disorders of the haem biosynthesis pathway characterised by acute neurovisceral symptoms, skin lesions or both. Each porphyria is caused by abnormal function of a separate enzymatic step resulting in a specific accumulation of haem precursors. Seven porphyrias are the consequence of a partial enzyme deficiency while a gain of function mechanism has been recently characterised in a novel porphyria. Acute porphyrias present with severe abdominal pain, nausea, constipation, confusion and seizure, which may be life threatening. Cutaneous porphyrias can be present with either acute painful photosensitivity or skin fragility and blisters. Rare recessive porphyrias usually manifest in early childhood with either severe chronic neurological symptoms or chronic haemolysis and severe cutaneous photosensitivity. Porphyrias are still underdiagnosed, but once they are suspected, and depending on the clinical presentation, a specific and simple front line test allows the diagnosis in all symptomatic patients. Diagnosis is essential to institute as soon as possible a specific treatment. Screening families to identify presymptomatic carriers is crucial to prevent chronic complications and overt disease by counselling on avoiding potential precipitants.

  17. [Relation between cholesterol levels and neuropsychiatric disorders].

    PubMed

    Martínez-Carpio, P A; Barba, J; Bedoya-Del Campillo, A

    A recent survey raised doubts about most of the associations between hypocholesterolemia and neuropsychiatric diseases. Nevertheless, there is scientific evidence (some very recent) that demonstrates a link between possible brain disorders and reduced levels of cholesterol. To conduct a systematic study of the literature that addresses the relation between low cholesterol levels in serum and neuropsychiatric disorders. Relevant papers were identified by means of a systematic search and selection of the literature on Medline (August 2008). The selected papers were reviewed using statistical analysis and critical-deductive reasoning. It is shown that low cholesterol levels in serum are associated and related to different neuropsychiatric disorders. Lowered cholesterol levels seem likely to be linked to higher rates of early death, suicide, aggressive and violent behaviour, personality disorders, and possibly depression, dementia and penal confinement among young males. Further studies are needed to confirm the evidence currently available and to relate more accurate diagnoses with hypocholesterolemia.

    Allergic rhinitis is the result of an immediate hypersensitivity immune response of the nasal mucosa to one or more allergens. Clinical features may be indistinguishable from non-allergic rhinitis. Accurate diagnosis demands specialized laboratory investigations, meticulous history and careful physical examination. Management includes control of allergen and irritant exposures, pharmacotherapy and immunotherapy. Recent development of intranasal corticosteroid aerosols has significantly reduced morbidity. Modified allergens for immunotherapy show promise but require further study. PMID:21286562

  20. Revisiting the roles of mast cells in allergic rhinitis and its relation to local IgE synthesis.

    PubMed

    Pawankar, R; Yamagishi, S; Yagi, T

    2000-01-01

    Mast cells are important effector cells in the immediate-phase allergic reaction. However, in recent years much evidence has accumulated on the versatile role of mast cells in allergic inflammation. The present article is an overview of the roles of mast cells in allergic inflammation, especially in light of the local production of IgE and the IgE-IgE receptor network. Although both nasal mast cells (NMC) and T cells in allergic rhinitics are important sources of Th2-type cytokines like IL-4 and IL-13, and can induce IgE synthesis, we report here that antigen-activated NMC can secrete greater levels of IL-4/IL-13 and induce increased levels of IgE synthesis than antigen-activated nasal T cells. Furthermore, IgE production can occur locally in the nasal mucosa (target organ) and IgE itself can enhance the Fc epsilon RI expression and subsequent mediator release from NMC, thus contributing to the perpetuation of on-going allergic inflammation. Again, mast cells can contribute to the late-phase allergic reaction not only via the upregulation of adhesion molecules like VCAM-1, but also through the interactions of NMC with the extracellular matrix proteins, and interaction of NMC with nasal epithelial cells (NEC). Thus, it is increasingly evident that mast cells are not only important for the genesis of the allergic reaction, but also contribute to the late-phase allergic reaction and on-going allergic inflammation.

    1988-07-01

    Pseudofolliculitis barbae, although not a serious medical problem, is certainly a distressing one for the affected patient. Its pathogenesis lies in an ingrown hair arising from the curved hair and follicle common in black men and women. Improper shaving techniques cause ingrown hairs through both transfollicular and extrafollicular mechanisms. Various treatment modalities exist, but there is no cure. Treatment must be individualized, as not all regimens will work for each patient. With diligence, pseudofolliculitis barbae can in many instances be controlled. Dermatitis papillaris capillitii is related to pseudofolliculitis barbae because its pathogenesis also lies in a curved hair and follicle. The treatment differs, however. Mild to moderately severe cases can be kept under good control with intralesional injections of steroid and a topical chloramphenicol and steroid cream mixture. Scarred or keloidal lesions may require surgery.

  2. The Treatment of Allergic Rhinitis

    PubMed Central

    1964-01-01

    Allergic inflammation of the nasal mucous membranes, like other atopic disorders, occurs primarily as the result of an antigenantibody reaction between external allergens and circulating skin-sensitizing antibodies. In addition, the disease process is frequently complicated by bacterial or viral infection. Effective treatment of allergic rhinitis, therefore, consists of: (1) changing the patient's environment in order to remove the offending allergens, (2) removing the patient from his environment, (3) altering the patient's response to environmental allergens by means of hyposensitization injections, (4) suppressing the allergic reaction with drugs, and (5) eliminating bacterial infection. Usually more than one of these therapeutic measures is required for the individual patient. PMID:14175878

    To investigate the effect of breast feeding on allergic disease in infants up to 2 years of age. A birth cohort of 4089 infants was followed prospectively in Stockholm, Sweden. Information about various exposures was obtained by parental questionnaires when the infants were 2 months old, and about allergic symptoms and feeding at 1 and 2 years of age. Duration of exclusive and partial breast feeding was assessed separately. Symptom related definitions of various allergic diseases were used. Odds ratios (OR) and 95% confidence intervals (CI) were estimated in a multiple logistic regression model. Adjustments were made for potential confounders. Children exclusively breast fed during four months or more exhibited less asthma (7.7% v 12%, OR(adj) = 0.7, 95% CI 0.5 to 0.8), less atopic dermatitis (24% v 27%, OR(adj) = 0.8, 95% CI 0.7 to 1.0), and less suspected allergic rhinitis (6.5% v 9%, OR(adj) = 0.7, 95% CI 0.5 to 1.0) by 2 years of age. There was a significant risk reduction for asthma related to partial breast feeding during six months or more (OR(adj) = 0.7, 95% CI 0.5 to 0.9). Three or more of five possible allergic disorders-asthma, suspected allergic rhinitis, atopic dermatitis, food allergy related symptoms, and suspected allergic respiratory symptoms after exposure to pets or pollen-were found in 6.5% of the children. Exclusive breast feeding prevented children from having multiple allergic disease (OR(adj) = 0.7, 95% CI 0.5 to 0.9) during the first two years of life. Exclusive breast feeding seems to have a preventive effect on the early development of allergic disease-that is, asthma, atopic dermatitis, and suspected allergic rhinitis, up to 2 years of age. This protective effect was also evident for multiple allergic disease.

    2015-01-01

    The activity-dependent structural and functional plasticity of dendritic spines has led to the long-standing belief that these neuronal compartments are the subcellular sites of learning and memory. Of relevance to human health, central neurons in several neuropsychiatric illnesses, including autism related disorders, have atypical numbers and morphologies of dendritic spines. These so-called dendritic spine dysgeneses found in individuals with autism related disorders are consistently replicated in experimental mouse models. Dendritic spine dysgenesis reflects the underlying synaptopathology that drives clinically relevant behavioral deficits in experimental mouse models, providing a platform for testing new therapeutic approaches. By examining molecular signaling pathways, synaptic deficits, and spine dysgenesis in experimental mouse models of autism related disorders we find strong evidence for mTOR to be a critical point of convergence and promising therapeutic target.

    Allergic rhinoconjunctivitis (AR/C), has been shown to impact upon athletic performance. The championships of the unique, amateur Irish sports of hurling and Gaelic football (collectively known as GAA) take place during the prime pollen months of summer. Elite GAA players must perform optimally when most exposed to pollen. Elite GAA subjects (n=254) underwent skin prick testing to 6 aeroallergens and completed a validated questionnaire (AQUA), producing a score indicating likelihood of having allergy. The prevalence of allergy (positive to at least one aeroallergen on SPT and positive AQUA score) was 27.1% (n=69). Sixteen and a half percent (n=42) of the subjects tested had grass pollen AR/C while 22% (n=54) had house dust mite AR/C, though none were on standard medical therapies or had used allergen-specific immunotherapy. Grass pollen AR/C prevalence appears as common in elite Irish athletes as it is in other countries. It appears to be mild rather than well controlled in these subjects.

    Insomnia disorder and obstructive sleep apnea are the two most common sleep disorders among adults. Historically, these conditions have been conceptualized as orthogonal, or insomnia has been considered a symptom of sleep apnea. Insomnia researchers have sought to exclude participants at risk for sleep-related breathing disorders (SRBD), and vice versa. In recent years, however, there has been a growing recognition of co-occurring insomnia disorder and SRBD and interest in the prevalence, consequences, and treatment of the two conditions when they co-occur. Although plagued by inconsistent diagnostic criteria and operational definitions, evidence from clinical and research samples consistently suggests high rates of comorbidity between the two disorders. More important, insomnia disorder and SRBD have additive negative effects. To date, only a few studies have explored the combined or sequential treatment of the conditions. Results support the importance of an integrated, interdisciplinary approach to sleep medicine. This article reviews the empirical literature to date and provides clinical recommendations as well as suggestions for future research.

    The impact of grass pollen-induced allergic rhinitis (AR) on classroom/work productivity and activities can be assessed with a specific instrument: the Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy Specific (WPAI-AS). This study evaluated the relationships between the WPAI-AS and other outcome measures in AR. Adolescents (aged 12-17) and adults (aged 18-65) consulting specialists for AR were enrolled in a four-week, multicentre, observational study. The management of AR was left to the physicians' discretion. Participants regularly rated the WPAI-AS, their symptoms (using the Rhinoconjunctivitis Total Symptom Score (RTSS) and a 0- to 100-mm visual analogue scale (VAS)) and quality of life (according to the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)). A total of 247 adolescents and 292 adults showed similar baseline impairments in classroom/work productivity and activities other than work. In both age groups, the WPAI-AS scores were moderately correlated with the RQLQ score and, to a lesser extent, with the VAS score and the RTSS. A multiple regression analysis indicated that the RQLQ score was a weak but statistically significant predictor of both impaired work/classroom productivity and daily activities. A 50-mm VAS cut-off categorized patients in whom AR had the greatest impact on productivity. Grass pollen-induced AR impairs work/classroom and daily activity to a similar extent in adults and adolescents. The weak-to-moderate correlations with AR symptom scores and quality-of-life scores suggest that a specific tool (such as the WPAI-AS) should be used to assess AR's impact on word/classroom productivity and daily activities. © 2016 John Wiley & Sons Ltd.

    The eye reacts to foreign substances through a variety of specific and non-specific defense mechanisms. Constantly exposed to a great variety of microorganisms, the eye is capable of protecting itself without altering its own structure and function. Its resistance relies upon anatomic and physiological properties of its external components (eyelids, tears, conjunctiva and cornea). Most of the times, the conjunctiva becomes affected, resulting in a clinical picture of conjunctivitis where allergy predominates, expressed as allergic rhinoconjunctivitis, allergic conjunctivitis, vernal keratoconjunctivitis, giant papillary conjunctivitis and flictenular conjunctivitis. The physiopathology is considered to be of type I reaction (IgE mediated). Frequent complains often associated with other allergic diseases are: pruritus, tearing, photofobia and ocular redness. The diagnosis of allergic conjunctivitis in done by means of a throughout clinical history, conjunctival citology and evaluation of specific IgE with immediate skin tests. Treatment is symptomatic (antihistamines, antibiotics and/or topic steroids), but prevention (environmental control and sodium cromoglycate) and specific immunotherapy must be considered.

    Multiple relationships between anxiety, allergic symptoms, and treatment difficulties have been observed. The aim of the present study was to estimate the prevalence of anxiety disorders in outpatients with various allergic diseases, to identify diagnostic cues or possible risk factors, and to test the usefulness of self-administered questionnaire screening at the allergy clinic. Six hundred forty-six (646) consecutive patients with rhinoconjunctivitis (59.3%), asthma (26.8%), or "other" allergy (13.9%), aged 16 to 65 years, completed self-administered questionnaires in six outpatient allergy clinics; 60 of the respondents also participated in structured psychiatric interviews. Anxiety was measured with the Spielberger State-Trait Anxiety. According to the interviews, STAI-T > 52 predicted with 86% accuracy a current psychiatric diagnosis, without differentiating between anxiety and depression. Using this threshold, the rate of anxiety and/or depressive disorders is estimated as 19% (95% CI: 15.9-22.1) in our unselected allergic outpatient sample; 46% of these patients never received any psychopharmacological treatment, indicating that anxiety related disorders are underdiagnosed and undertreated. Risk indicators were female gender; asthma; perennial symptoms; sleep problems; nonspecific allergy triggers like strong emotions; stressful situations; and considerable limitation in everyday activities attributed to the allergic symptoms. Our findings confirm a high rate of anxiety and/or depressive disorders in patients visiting the allergy clinic. Self-administered questionnaires such as STAI-T provide reliable help for the identification of these frequent psychiatric problems.

    Mutations in MYH9 gene encoding the nonmuscle myosin heavy chain IIA (NMMHC-IIA) are related to a number of rare autosomal-dominant disorders which has been known as May-Hegglin disease, Sebastian syndrome, Fechtner syndrome and Epstein syndrome. Their common clinical features are congenital macrothrombocytopaenia and polymorphonuclear inclusion bodies, in addition to a variable risk of developing proteinuria, chronic kidney disease progressing toward end stage, sensorineural deafness and presenile cataracts. The term MYH9 related disease (MYH9-RD) describes the variable expression of a single illness encompassing all previously mentioned hereditary disorders. Renal involvement in MYH9- RD has been observed in 30% of patients. Mutant MYH9 protein, expressed in podocytes, mesangial and tubular cells, plays a main role in foot process effacement and in development of nephropathy. Interestingly, the MYH9 gene is currently under investigation also for his possible contribution to many other non-hereditary glomerulopathies such as focal global glomerulosclerosis (hypertensive nephrosclerosis), idiopathic focal segmental glomerulosclerosis, C1q nephropathy and HIV-associated nephropathy. In this review we are aimed to describe renal diseases related to MYH9 disorders, from the hereditary disease to the acquired disorders, in which MYH9-gene acts as a "renal failure susceptibility gene".

    MicroRNAs (miRNAs), a class of small non-coding RNAs of 18–24 nucleotides in length, function to posttranscriptionally regulate protein expression. miR-155 was one of the first identified and, to date, the most studied miRNA, and has been linked to various cellular processes such as modulation of immune responses and oncogenesis. Previous studies have identified miR-155 as a crucial positive regulator of Th1 immune response in autoimmune diseases, but as a suppressor of Th2 immunity in allergic disorders. However, recent studies have found new evidence that miR-155 plays an indispensible role in allergic asthma. This review summarizes the recent findings with respect to miR-155 in immune responses and the underlying mechanisms responsible for miR-155-related allergic diseases, as well as the similarities between miR-155 and glucocorticoids in immunity.

    Many reports have been published concerning how psychosocial stress influences the occurrence and progression of allergic diseases such as bronchial asthma and atopic dermatitis. As for asthma, a typical allergic disease often accompanied by psychosomatic related problems, the Global Initiative for Asthma (GINA), international medical guidelines for asthma, describes psychosocial problems as causative factors of poor asthma control and as risk factors for asthma exacerbation, even if symptoms are well controlled. However, because there is little high quality evidence for effective treatments for asthma patients with psychosocial problems, concrete assessments and treatments for such problems is scarcely described in GINA. Therefore, psychosomatic intervention for asthma patients is not effectively conducted on a worldwide scale. In contrast, the "Japanese Guidelines for the Diagnosis and Treatment of Psychosomatic Diseases" describe the assessment and treatment of psychosomatic disorders in detail. In the guidelines, psychosocial factors are classified into five categories; 1) Relation between stress and asthma occurrence or progression, 2) Relation between emotion and asthma symptoms, 3) Problems related to a patient's character and behaviors, 4) Problems of daily life and Quality of Life (QOL), and 5) Problems related to family relationships and life history. The employment of a self-administered questionnaire, the "Psychosomatic Questionnaire related to Asthmatic Occurrence and Progression", is useful for clarifying psychosocial factors and for setting up treatment strategies according to the problems identified. The Japanese guidelines have been proven to be useful, but empirical evidence for their effectiveness is still relatively limited. It will be necessary in the future to accumulate high-quality evidence and to revise the psychosomatic approaches in the guidelines that are universally valid.

    Extrinsic allergic alveolitis (EAA) caused by inhaled organic environmental allergens can progress to a fibrotic end-stage lung disease. Neovascularization plays an important role in pathogenesis of pulmonary fibrosis. The aim of this study was to assess the effect of sera from EAA patients on the angiogenic capability of normal peripheral human mononuclear cells (MNC) in relation to the clinical, radiological, and functional changes. The study population consisted of 30 EAA patients and 16 healthy volunteers. Routine pulmonary function tests were undertaken using ERS standards. As an angiogenic test, leukocyte-induced angiogenesis assay according to Sidky and Auerbach was used. Compared with sera from healthy volunteers, sera from our EAA patients significantly stimulated angiogenesis (P < 0.001). However, sera from healthy donors also stimulated angiogenesis compared to PBS (P < 0.001). No correlation was found between serum angiogenic activity and clinical symptoms manifested by evaluated patients. A decrease in DLco and in lung compliance in EAA patients was observed but no significant correlation between pulmonary functional tests and serum angiogenic activity measured by the number of microvessels or an angiogenesis index was found. However, the proangiogenic effect of sera from EAA patients differed depending on the stage of the disease and was stronger in patients with fibrotic changes. The present study suggests that angiogenesis plays a role in the pathogenesis of EAA. It could be possible that the increase in the angiogenic activity of sera from EAA patients depends on the phase of the disease.

    In patients with multiple system atrophy (MSA), sleep related breathing disorders (SRBD), including obstructive and central sleep apnea, vocal cord abductor paralysis and dysrhythmic breathing pattern, are frequently observed. SRBD may have a considerable impact on variation of autonomic nervous activity during sleep. The previous studies correlated upper airway muscle dysfunction related parkinsonism with increased prevalence of SRBD in patients with Parkinson's disease (PD). However, recently, the clinical significance of SRBD and its impact on sleepiness and disease severity have been debated. In this review, we discuss sleep and autonomic function, especially, SRBD in PD and related disorders, including the previous studies from our department.

    Obstructive sleep apnea (OSA) syndrome is a sleep-related breathing disorder, due mainly to peripheral causes, characterized by repeated episodes of obstruction of the upper airways, associated with snoring and arousals. The sleep process fragmentation and oxygen desaturation events lead to the major health problems with numerous pathophysiological consequences. Micro-arousals occurring during sleep are considered to be the main causal factor for night jaw-closing muscles activation called bruxism. Bruxism is characterized by clenching and grinding of the teeth or by bracing or thrusting of the mandible. The causes of bruxism are multifactorial and are mostly of central origin. Among central factors there are secretion disorders of central nervous system neurotransmitters and basal ganglia disorders. Recently, sleep bruxism has started to be regarded as a physiological phenomenon occurring in some parts of the population. In this article we present an evaluation of the relationship between OSA and sleep bruxism. It has been reported that the frequency of apneic episodes and that of teeth clenching positively correlates in OSA. However, clinical findings suggest that further studies are needed to clarify sleep bruxism pathophysiology and to develop new approaches to tailor therapy for individual patients with concomitant sleep bruxism and OSA.

    Among artists, musicians may suffer from occupational skin problems; notwithstanding, these conditions have been rarely reviewed. The characteristics of individual performer and the type of instrument will determine the kind of disease. Moreover, the hours that the musician spent to advance artistic skill may influence the severity. The frequency and risk factors of instrument-related skin disorders in musicians from southern Italy were analyzed. An observational study was conducted in 628 musicians. A questionnaire including questions related to age, sex, instrument played, musical activity, previous or current skin disorders, and impact of skin symptoms on music making was submitted. Of 628 musicians, 199 (31.7%) reported suffering from at least 1 skin disease. Cutaneous diseases likely directly correlated with the use of the musical instrument were found in 129 (20.5%) of the 628 subjects. In particular, different patterns of irritant contact dermatitis were found. Skin conditions may be a significant problem in professional instrumentalists. They are mainly related to musical activity. Preventive measures should be established.

    Helicobacter pylori (H. pylori) infection is investigated in gastric diseases even during pregnancy. In particular, this Gram-negative bacterium seems to be associated with hyperemesis gravidarum, a severe form of nausea and vomiting during pregnancy. During the last decade, the relationship among H. pylori and several extra-gastric diseases strongly emerged in literature. The correlation among H. pylori infection and pregnancy-related disorders was mainly focused on iron deficiency anemia, thrombocytopenia, fetal malformations, miscarriage, pre-eclampsia and fetal growth restriction. H. pylori infection may have a role in the pathogenesis of various pregnancy-related disorders through different mechanisms: depletion of micronutrients (iron and vitamin B12) in maternal anemia and fetal neural tube defects; local or systemic induction of pro-inflammatory cytokines release and oxidative stress in gastrointestinal disorders and pre-eclampsia; cross-reaction between specific anti-H. pylori antibodies and antigens localized in placental tissue and endothelial cells (pre-eclampsia, fetal growth restriction, miscarriage). Since H. pylori infection is most likely acquired before pregnancy, it is widely believed that hormonal and immunological changes occurring during pregnancy could activate latent H. pylori with a negative impact not only on maternal health (nutritional deficiency, organ injury, death), but also on the fetus (insufficient growth, malformation, death) and sometime consequences can be observed later in life. Another important issue addressed by investigators was to determine whether it is possible to transmit H. pylori infection from mother to child and whether maternal anti-H. pylori antibodies could prevent infant’s infection. Studies on novel diagnostic and therapeutic methods for H. pylori are no less important, since these are particularly sensitive topics in pregnancy conditions. It could be interesting to study the possible correlation between H

    Stimulant–related disorders (SRD) continue to be an important public health problem for which there are presently no approved pharmacotherapies. Although behavioral interventions provide some benefit response varies. The development of novel and effective pharmacotherapies continues to be a research priority. Understanding neural mechanisms critical to the action of stimulants has helped reveal several potential pharmacotherapies that have already shown promise in controlled clinical trials. Common to some of these medications is the ability to reverse neural deficits in individuals with SRD. Results from thoroughly conducted clinical trials continue to broaden our knowledge increasing the possibility of soon developing effective pharmacotherapies for SRD. PMID:24142188

  5. Decreased Circulating Interleukin-35 Levels Are Related to Interleukin-4-Producing CD8+ T Cells in Patients with Allergic Asthma.

    Interleukin (IL)-35 is a newly discovered suppressive cytokine and has been shown to alleviate inflammatory and autoimmune diseases. The purpose of this study was to investigate immunomodulatory capacity of IL-35 in patients with allergic asthma. IL-35 mRNA expression levels in peripheral blood mononuclear cells (PBMCs) were detected by quantitative real-time PCR (qPCR). The frequencies of cytotoxic T cells (Tc)1, Tc2 and Tc17 cells were measured by flow cytometry. Plasma levels of IL-35, interferon (IFN)-γ, IL-4, and IL-17 were examined by enzyme-linked immunosorbent assay (ELISA). The correlations between plasma IL-35 levels and Tc1, Tc2, and Tc17 cytokine production in allergic asthmatics (n = 25) and healthy controls (n = 12) were analyzed by Pearson's test. IL-35 protein and mRNA expression levels were down-regulated in allergic asthmatics compared with healthy controls. The frequencies of Tc2 and Tc17 cells were significantly increased in patients with asthma, and the frequency of Tc1 cells did not differ between asthmatic patients and healthy controls. Similarly, plasma levels of IL-4 and IL-17 were significantly increased in asthmatic patients, while there was no difference in IFN-γ levels between allergic asthma patients and healthy controls. More importantly, plasma IL-35 protein levels were negatively correlated with the frequency of IL-4-producing CD8+ T (Tc2) cells and with the IL-4 level in patients with allergic asthma. Our results suggest that decreased circulating IL-35 levels could contribute to the pathogenesis of allergic asthma by regulating CD8+ T cells.

  6. ALLERGIC IRRITABILITY

    The allergic irritability of closely inbred guinea pigs as represented by their capacity to produce hemolytic antibodies for beef and sheep corpuscles, and agglutinins for Bacillus typhosus and Bacillus abortus (Bang) differs by families and therefore is at least partly dependent on inherited characteristics. These differences show an imperfect but suggestive correlation with the differences in resistance of the same families to inoculation tuberculosis as previously determined by Wright and Lewis. The differences in antibody production also show an imperfect correlation with the differences in response in the anaphylactic reaction complex as previously determined by Lewis and Loomis. These studies suggest very strongly that the allergic irritability is one of the several inheritable characters which form a partial basis for the natural resistance to tuberculosis. The antibody-producing capacity is only satisfactorily defined when minimal or moderate amounts of antigen are used and this in single treatments. The irregularities in experimental result when repeated treatments or very large single treatments are used suggest that antibody production in the second or "acquired capacity" phase may rest on a somewhat different fundamental basis than the latent or potential natural capacity. There is some very slight evidence that production in the second phase may also be influenced by inherited qualities. PMID:19869422

    Until recently the prevalence of asthma in Sweden was assessed to be 2-3 per cent. An increase in the prevalence of asthma and allergic rhinitis was noted among new conscripts undergoing health work-ups prior to military service with the most marked increase in northern Sweden, were 5 per cent of conscripts were reported to have asthma. In southern Sweden the prevalence remained about 2 per cent. More recent questionnaire studies in mid- and southern Sweden have reported similar rates of respiratory symptoms and use of anti-asthmatic drugs as in northern Sweden, suggesting that there may be no difference in asthma prevalence between the north and the south of the country. The exact prevalence of allergic diseases among Swedish adults is still not clear, but 40 per cent of adults in northern Sweden report that they often have wheezing in the chest, attacks of breathlessness, longstanding cough or sputum production. In questionnaire studies among children about 40 per cent of respondents have reported that they had asthma, allergic rhinitis or other type of hypersensitivity. The absence of generally accepted diagnostic criteria for asthma and allergic disorders in epidemiological studies makes comparison of prevalence difficult. It is thus not possible to be sure that the prevalence of asthma and allergic disorders in Sweden has recently increased. Risk factors for the development of asthma and allergic disorders are under study in Sweden. Several studies report an association in children between urban living and allergic disorders.

    Epidemiological studies indicate sex-related differences among functional gastrointestinal disorders (FGIDs) wherein females are more likely to receive a diagnosis than their male counterparts. However, the mechanism by which females exhibit an increased vulnerability for development of these pathophysiologies remains largely unknown, and therapeutic treatments are limited. The current chapter focuses on clinical research outlining our current knowledge of factors that contribute to the female predominance among FGID patients such as the menstrual cycle and sex hormones. In addition, we will discuss progress in preclinical research, including animal models, which serve as valuable tools for the investigation of the development and long term manifestation of symptoms observed within the patient population. Although much progress has been made, additional longitudinal studies in both clinical and preclinical research are necessary to identify more specific mechanisms underlying sex-related differences in FGIDs as well as targets for improved therapeutic approaches.

    Many studies have shown consistent associations between evident indoor dampness or mold and respiratory or allergic health effects, but causal links remain unclear. Findings on measured microbiologic factors have received little review. We conducted an updated, comprehensive review on these topics. We reviewed eligible peer-reviewed epidemiologic studies or quantitative meta-analyses, up to late 2009, on dampness, mold, or other microbiologic agents and respiratory or allergic effects. We evaluated evidence for causation or association between qualitative/subjective assessments of dampness or mold (considered together) and specific health outcomes. We separately considered evidence for associations between specific quantitative measurements of microbiologic factors and each health outcome. Evidence from epidemiologic studies and meta-analyses showed indoor dampness or mold to be associated consistently with increased asthma development and exacerbation, current and ever diagnosis of asthma, dyspnea, wheeze, cough, respiratory infections, bronchitis, allergic rhinitis, eczema, and upper respiratory tract symptoms. Associations were found in allergic and nonallergic individuals. Evidence strongly suggested causation of asthma exacerbation in children. Suggestive evidence was available for only a few specific measured microbiologic factors and was in part equivocal, suggesting both adverse and protective associations with health. Evident dampness or mold had consistent positive associations with multiple allergic and respiratory effects. Measured microbiologic agents in dust had limited suggestive associations, including both positive and negative associations for some agents. Thus, prevention and remediation of indoor dampness and mold are likely to reduce health risks, but current evidence does not support measuring specific indoor microbiologic factors to guide health-protective actions.

    2016-01-01

    Opinion statement Attention deficit/hyperactivity disorder (ADHD) is a disorder characterized by impulsivity, hyperactivity, and inattention. Binge-eating behavior is often impulsive and is the hallmark of the two eating disorders, binge-eating disorder (BED) and bulimia nervosa (BN), both of which are associated with significant health impairment. Bingeing behavior is also seen in the binge purge subtype of anorexia nervosa. Individuals with AN of the binge purge subtypes, BN and BED, have been found to exhibit impulsive behaviors that are often not limited to binge eating alone. There is preliminary evidence linking ADHD to BN and to BED in both adults and children. The neurobiological mechanisms behind these associations are only beginning to emerge; however, they suggest that impulse control deficits may play a role in these eating disorders. Additionally, although they may not meet full criteria for one of these eating disorders, some adults and children with ADHD present with dysregulated, impulsive eating disorder behaviors and there is a growing association between ADHD, obesity, and binge-eating behavior in both children and adults. The relationship between ADHD and binge eating is novel, supported by growing evidence and worthy of further research. We will review the underlying neurobiological underpinnings, neuroimaging data, and possible psychopharmacological treatment options, which target both ADHD and binge-eating behaviors as well as future research and treatment directions.

    Cytokines are intercellular mediators involved in viral control and liver damage being induced by infection with hepatitis C virus (HCV). The complex cytokine network operating during initial infection allows a coordinated, effective development of both innate and adaptive immune responses. However, HCV interferes with cytokines at various levels and escapes immune response by inducing a T-helper (Th)2/T cytotoxic 2 cytokine profile. Inability to control infection leads to the recruitment of inflammatory infiltrates into the liver parenchyma by interferon (IFN)-gamma-inducible CXC chemokine ligand (CXCL)-9, -10, and -11 chemokines, which results in sustained liver damage and eventually in liver cirrhosis. The most important systemic HCV-related extrahepatic diseases—mixed cryoglobulinemia, lymphoproliferative disorders, thyroid autoimmune disorders, and type 2 diabetes—are associated with a complex dysregulation of the cytokine/chemokine network, involving proinflammatory and Th1 chemokines. The therapeutical administration of cytokines such as IFN-alpha may result in viral clearance during persistent infection and reverts this process. PMID:22611419

    Specific physical and chemical agents found in the workplace and in the general environment are responsible for characteristic pathologic processes within the nervous system. It has been shown that many neurotoxic agents produce a dose-related spectrum of impairment ranging from mild slowing of nerve conducting velocity or prolongation in reaction time to neuropathy and frank encephalopathy. Clinical manifestations are determined by the agent involved, by the dose of exposure, the vulnerability of the cellular target, the ability of the organism to metabolize and excrete the agent, and the ability to repair damage. An occupational history, including evaluation of evidence of specific agents and job history, is a critical component in the clinical management of individuals with suspect neurotoxic disease. Environmentally-induced disorders can be prevented by appropriate environmental controls. Prevention of neurotoxic disease is a complex process requiring continuous involvement of public health agencies and strong scientific research.

    Synopsis Post-traumatic Stress Disorder (PTSD) is a prevalent anxiety disorder. PTSD typically follows a psychologically traumatic event, and thus has a recognizable point of onset. PTSD symptoms are present shortly after an exposure to a traumatic event, abate with time in the majority of those who initially express them, and leave a significant minority with chronic PTSD. PTSD may be treated with pharmacotherapy or psychotherapy. The treatment of the early expressions of disorder constitutes a separate domain of theory and research. The treatment of chronic PTSD often stabilizes the condition, but rarely produces stable remission. This chapter reviews the empirical evidence on the treatment of acute and chronic PTSD, outlines similarities and differences between PTSD and other Axis I disorders, evaluates new therapeutic approaches, and discusses the implications of current knowledge for the forthcoming DSM V.

    Allergies are prevalent throughout the United States and impose a substantial quality of life and economic burden. The potential effect of climate change has an impact on allergic disorders through variability of aeroallergens, food allergens and insect-based allergic venoms. Data suggest allergies (ocular and nasal allergies, allergic asthma and sinusitis) have increased in the United States and that there are changes in allergies to stinging insect populations (vespids, apids and fire ants). The cause of this upward trend is unknown, but any climate change may induce augmentation of this trend; the subspecialty of allergy and immunology needs to be keenly aware of potential issues that are projected for the near and not so distant future.

    This article addresses somatoform disorders, which remain a challenging problem in contemporary psychiatry. Inadequate responses to stressors play a significant role in their development. The term "somatoform disorders" refers to illnesses that were previously termed "psychosomatic". This article defines disorders according to the ICD-10 classification while highlighting important differences between this and the DSM-IV classification. The article reviews expert opinions concerning somatoform disorders, particularly in regard to somatization, hypochondriasis and autonomic dysfunction in these conditions. Attention is drawn to the relationship between somatoform disorders and other psychiatric conditions including depression, anxiety disorders and personality disorders as well as to actual non-psychiatric illnesses. The influence of cultural background, sex and age is discussed. Difficult clinical conditions such as fibromyalgia and Münchhausen syndrome are also considered.

    There is an ongoing debate whether transdiagnostic neural mechanisms are shared by different anxiety-related disorders or whether different disorders show distinct neural correlates. To investigate this issue, studies controlling for design and stimuli across multiple anxiety-related disorders are needed. The present functional magnetic resonance imaging study investigated neural correlates of visual disorder-related threat processing across unmedicated patients suffering from panic disorder (n = 20), social anxiety disorder (n = 20), dental phobia (n = 16) and post-traumatic stress disorder (n = 11) relative to healthy controls (HC; n = 67). Each patient group and the corresponding HC group saw a tailor-made picture set with 50 disorder-related and 50 neutral scenes. Across all patients, increased activation to disorder-related v. neutral scenes was found in subregions of the bilateral amygdala. In addition, activation of the lateral amygdala to disorder-related v. neutral scenes correlated positively with subjective anxiety ratings of scenes across patients. Furthermore, whole-brain analysis revealed increased responses to disorder-related threat across the four disorders in middle, medial and superior frontal regions, (para-)limbic regions, such as the insula and thalamus, as well as in the brainstem and occipital lobe. We found no disorder-specific brain responses. The results suggest that pathologically heightened lateral amygdala activation is linked to experienced anxiety across anxiety disorders and trauma- and stressor-related disorders. Furthermore, the transdiagnostically shared activation network points to a common neural basis of abnormal responses to disorder-related threat stimuli across the four investigated disorders.

    Novel strategies are evaluated for management of allergic rhinitis and asthma in patients co-afflicted with both disorders. It is hypothesized that the platelet activating factor receptor antagonist ginkgolide B (GB) and the carotenoid antioxidant astaxanthin (ASX) interact with antihistamines cetirizine dihydrochloride (CTZ) and azelastine (AZE) to potentiate their ability to downregulate potentially pathological immune activation. Peripheral blood mononuclear cells from asthmatics and healthy subjects, cultured 24 hours with 50 μg/ml phytohemaglutinin (PHA) or PHA plus each drug are analyzed by flow cytometry for expression of CD25+ or HLA-DR+ by CD3+ (T cells). Results are reported as stimulation indices for CD3+CD25+ (SICD3+CD25+) and CD3+HLA-DR+ (SICD3+HLADR+) cells in cultures treated with PHA alone, versus cultures treated with both PHA and drugs. Optimal suppression of activated cells was observed in cultures stimulated with ASX 10-6 M + CTZ 10-6 M (SICD3+CD25+, p = 0.016; SICD3+HLADR, p = 0.012); ASX 10-6 M + AZE 10-6 M (SICD3+CD25+, p = 0.012; SICD3+HLADR, p = 0.015); GB 10-6 M + CTZ 10-6 M (SICD3+CD25+, p = 0.024, SICD3+HLADR+, p = 0.019). Results demonstrate improved activity of antihistamines by 2 phytochemicals, suggesting dosing strategies for animal trials of ASX- or GB-augmented formulations for seasonal allergic rhinitis and asthma.

  6. Olfaction in Parkinson's disease and related disorders

    PubMed Central

    Doty, Richard L.

    2012-01-01

    Olfactory dysfunction is an early ‘pre-clinical’ sign of Parkinson's disease (PD). The present review is a comprehensive and up-to-date assessment of such dysfunction in PD and related disorders. The olfactory bulb is implicated in the dysfunction, since only those syndromes with olfactory bulb pathology exhibit significant smell loss. The role of dopamine in the production of olfactory system pathology is enigmatic, as overexpression of dopaminergic cells within the bulb's glomerular layer is a common feature of PD and most animal models of PD. Damage to cholinergic, serotonergic, and noradrenergic systems is likely involved, since such damage is most marked in those diseases with the most smell loss. When compromised, these systems, which regulate microglial activity, can influence the induction of localized brain inflammation, oxidative damage, and cytosolic disruption of cellular processes. In monogenetic forms of PD, olfactory dysfunction is rarely observed in asymptomatic gene carriers, but is present in many of those that exhibit the motor phenotype. This suggests that such gene-related influences on olfaction, when present, take time to develop and depend upon additional factors, such as those from aging, other genes, formation of α-synuclein- and tau-related pathology,or lowered thresholds to oxidative stress from toxic insults. The limited data available suggest that the physiological determinants of the early changes in PD-related olfactory function are likely multifactorial and may include the same determinants as those responsible for a number of other non-motor symptoms of PD, such as dysautonomia and sleep disturbances.

    It is unknown why allergic symptoms do not develop in all sensitized children. We analyzed prospectively the postnatal secretory IgA (SIgA) development and whether high SIgA levels would protect sensitized infants from developing allergic symptoms. Salivary total IgA and SIgA levels were determined by ELISA, and allergy development was investigated at 3, 6, and 12 mo and at 2 and 5 y in two birth cohorts in Estonia (n = 110) and Sweden (n = 91), two geographically adjacent countries with different living conditions and allergy incidence. Total and SIgA levels increased with age, reaching adult levels at the age of 5. Virtually, all salivary IgA in Estonian children was in the secretory form, while a major part of IgA in Swedish saliva lacked the secretory component up to 2 y of age. In Sweden, high levels of salivary IgA without secretory component correlated inversely with house dust endotoxin levels. High SIgA levels were associated with less development of allergic symptoms in sensitized Swedish children. In conclusion, postnatal maturation of the salivary SIgA system proceeds markedly slower in Swedish than Estonian children, possibly as a consequence of low microbial pressure. SIgA may limit allergy-mediated tissue damage at mucosal surfaces in sensitized individuals.

  8. Factitious disorders and malingering in relation to functional neurologic disorders.

    PubMed

    Bass, C; Halligan, P

    2017-01-01

    Interest in malingering has grown in recent years, and is reflected in the exponential increase in academic publications since 1990. Although malingering is more commonly detected in medicolegal practice, it is not an all-or-nothing presentation and moreover can vary in the extent of presentation. As a nonmedical disorder, the challenge for clinical practice remains that malingering by definition is intentional and deliberate. As such, clinical skills alone are often insufficient to detect it and we describe psychometric tests such as symptom validity tests and relevant nonmedical investigations. Finally, we describe those areas of neurologic practice where symptom exaggeration and deception are more likely to occur, e.g., postconcussional syndrome, psychogenic nonepileptic seizures, motor weakness and movement disorders, and chronic pain. Factitious disorders are rare in clinical practice and their detection depends largely on the level of clinical suspicion supported by the systematic collection of relevant information from a variety of sources. In this chapter we challenge the accepted DSM-5 definition of factitious disorder and suggest that the traditional glossaries have neglected the extent to which a person's reported symptoms can be considered a product of intentional choice or selective psychopathology largely beyond the subject's voluntary control, or more likely, both. We present evidence to suggest that neurologists preferentially diagnose factitious presentations in healthcare workers as "hysterical," possibly to avoid the stigma of simulated illness.

    A further example of diffuse pulmonary hypersensitivity to an inhaled organic antigen is reported. A 42-year-old maltworker, who developed an illness resembling farmer's lung, was found to have been heavily exposed to the spores of Aspergillus clavatus. Precipitating and complement-fixing antibodies against an extract of A. clavatus were detected in his serum, a late (Arthus-type) reaction was produced by intradermal injection of the same extract, and a pyrexial reaction, accompanied by a reduction in forced vital capacity and carbon monoxide transfer factor, occurred 6 hours after the inhalation of spores of A. clavatus. Two of the patient's four workmates complained of similar but less severe symptoms, and their sera also contained specific antibodies. Although the spores of A. clavatus and of Cryptostroma corticale, the fungus responsible for maple-bark disease, are much larger than the 1 μ spores of Micropolyspora sp., they may give rise to a diffuse pulmonary hypersensitivity reaction indistinguishable from that observed in farmer's lung. This suggests that the occurrence of such a reaction is not necessarily related to the size of the inhaled particles, and there is reason to believe that the concentration of spores or other antigenic particles in the inspired air may in this respect be more important than their size. The pulmonary hypersensitivity in this group of disorders appears to be a precipitin-mediated (type III) response to a variety of inhaled antigens, but some of these antigens may in certain patients, presumably atopic individuals, also provoke a reagin-mediated (type I) bronchial hypersensitivity reaction. It is suggested that a term such as `allergic alveolitis' or `extrinsic allergic alveolitis' may suitably be used to describe the group of diseases caused by pulmonary hypersensitivity to inhaled organic antigens.

    In the last 10 years, numerous neurobiological studies have been conducted on Internet addiction or Internet use disorder. Various neurobiological research methods - such as magnetic resonance imaging; nuclear imaging modalities, including positron emission tomography and single photon emission computed tomography; molecular genetics; and neurophysiologic methods - have made it possible to discover structural or functional impairments in the brains of individuals with Internet use disorder. Specifically, Internet use disorder is associated with structural or functional impairment in the orbitofrontal cortex, dorsolateral prefrontal cortex, anterior cingulate cortex, and posterior cingulate cortex. These regions are associated with the processing of reward, motivation, memory, and cognitive control. Early neurobiological research results in this area indicated that Internet use disorder shares many similarities with substance use disorders, including, to a certain extent, a shared pathophysiology. However, recent studies suggest that differences in biological and psychological markers exist between Internet use disorder and substance use disorders. Further research is required for a better understanding of the pathophysiology of Internet use disorder.

  12. Early diagnosis of sleep related breathing disorders

    Obstructive sleep apnea (OSA) being the most frequent sleep related breathing disorder results in non-restorative sleep, an increased cardiovascular morbidity and mortality as well as an elevated number of accidents. In Germany at least two million people have to be expected. If obstructive sleep apnea is diagnosed early enough then sleep may regain its restorative function, daytime performance may be improved and accident risk as well as cardiovascular risk may be normalised. This review critically evaluates anamnestic parameters, questionnaires, clinical findings and unattended recordings during sleep regarding their diagnostic accurracy in recognising OSA. There are numerous tools with insufficient results or too few data disqualifying them for screening for OSA. Promising preliminary results are published concerning neural network analysis of a high number of clinical parameters and non-linear analysis of oximetry itself or in combination with heart rate. Nasal pressure recordings can be used for risk estimation even without expertise in sleep medicine. More data is needed. Unattended portable monitoring used by qualified physicians is the gold standard procedure when screening methods for OSA are compared. It has a very high sensitivity and specificity well documented by several meta-analyses. PMID:22073090

    2016-02-01

    This review identifies the diverse and variable clinical presentations associated with epilepsy that may create challenges in diagnosis and treatment. Epilepsy has recently been redefined as a disease characterized by one or more seizures with a relatively high recurrence risk (ie, 60% or greater likelihood). The implication of this definition for therapy is that antiepileptic drug therapy may be initiated following a first seizure in certain situations.EEG remains the most commonly used study in the evaluation of people with epilepsy. Routine EEG may assist in diagnosis, classification of seizure type(s), identification of treatment, and monitoring the efficacy of therapy. Video-EEG monitoring permits seizure classification, assessment of psychogenic nonepileptic seizures, and evaluation of candidacy for epilepsy surgery. MRI is pivotal in elucidating the etiology of the seizure disorder and in suggesting the localization of seizure onset. This article reviews the new International League Against Epilepsy practical clinical definition for epilepsy and the differential diagnosis of other physiologic paroxysmal spells, including syncope, parasomnias, transient ischemic attacks, and migraine, as well as psychogenic nonepileptic seizures. The initial investigational approaches to new-onset epilepsy are considered, including neuroimaging and neurophysiologic investigations with interictal and ictal video-EEG. Neurologists should maintain a high index of suspicion for epilepsy when children or adults present with a single paroxysmal spell or recurrent episodic events.

    Rhinitis, or the “stuffy nose”, can be allergic or non-allergic in nature. Accurate diagnosis depends on a well-taken history and physical examination. Non-allergic rhinitis is characterized by absent elevation in allergen-specific IgE. Treatment is based, if possible, on the etiology. Surgical procedures on the turbinates are often needed to allow improvement. Allergic rhinitis is characterized by an increase in allergen-specific IgE. Treatment may involve environmental control, pharmocologic agents, or, finally, immunotherapy. Successful treatment requires accurate assessment of the offending agent and proper use of the above-mentioned modalities. PMID:21263880

    The allergic rhinitis is the most common immune disorder with a lifetime prevalence of 24% and one of the most common chronic diseases at all--with tendency to rise. It occurs in childhood and influences the patients' social life, school performance and labour productivity. Furthermore the allergic rhinitis is accompanied by a lot of comorbidities, including conjunctivitis, asthma bronchiale, food allergy, neurodermatitis and sinusitis. For example the risk for asthma is 3.2-fold higher for adults with allergic rhinitis than for healthy people.

  16. Mas-related G protein coupled receptor-X2: A potential new target for modulating mast cell-mediated allergic and inflammatory diseases

    PubMed Central

    Ali, Hydar

    2017-01-01

    Mast cells (MCs) are tissue resident immune cells that are best known for their roles in allergic and inflammatory diseases. In addition to the high affinity IgE receptor (FcεRI), MCs express numerous G protein coupled receptors (GPCRs), which are the most common targets of drug therapy. Neurokinin 1 receptor (NK-1R) is expressed on MCs and contributes to IgE and non-IgE-mediated responses in mice. Although NK-1R antagonists are highly effective in modulating experimental allergic and inflammatory responses in mice they lack efficacy in humans. This article reviews recent findings that demonstrate that while neuropeptides (NPs) activate murine MCs via NK-1R and Mas related G protein coupled receptor B2 (MrgprB2), they activate human MCs via Mas-related G protein coupled receptor X2 (MRGPRX2). Interestingly, conventional NK-1R antagonists have off-target activity against mouse MrgprB2 but not human MRGPRX2. These findings suggest that the failure to translate studies with NK-1R antagonists from in vivo mouse studies to the clinic likely reflects their lack of effect on human MRGPRX2. A unique feature of MRGPRX2 that distinguishes it from other GPCRs is that it is activated by a diverse group of ligands that include; neuropeptides, cysteine proteases, antimicrobial peptides and cationic proteins released from activated eosinophils. Thus, the development of small molecule MRGPRX2-specific antagonists or neutralizing antibodies may provide new targets for the treatment of MC-mediated allergic and inflammatory diseases.

    Atopic disorders are a major global health problem. The prevalence of asthma, allergic rhinitis and atopic dermatitis has been increasing over the last four decades, both in the industrialized and developing countries. It seems to be related to changes in the social structure, increasing industrialization, pollution and dietary changes. Many hypotheses link the allergy epidemic to stringent hygiene, dominance of a westernized lifestyle and an accelerated pace of life. Dietary antioxidants, lipids, sodium, vitamin D seem also to be implicated. We endeavour to review the most relevant theories with a special emphasis on the hygiene, antioxidative, lipid and air pollution hypotheses. It is however important to note that none of them explains all the aspects of unprecedented rise in the prevalence of allergic disorders. A complex interplay between host's immune response, invading pathogens, diversity of environmental factors and genetic background seems to be of a particular importance. Current allergy epidemic is multifactorial and basic and epidemiologic studies are warranted to further our understanding of this phenomenon. PMID:25097472

    2014-07-01

    Huntington's disease is the most frequent form of the hereditary choreas and has a multifaceted phenotype including cognitive and psychiatric impairment. The disorder is due to a dynamic mutation, which also influences the onset age of the disorder. Other genetic modifiers of the HD phenotypes have been suggested but often not confirmed by independent studies. Several syndromes with similar presentation have different genetic backgrounds, including the neuroacanthocytoses, mainly choreoacanthocytosis and MacLeod syndrome as a result of mutations in chorein and Kell protein, respectively, but also benign hereditary chorea, owing to mutations in NKX-2-1, and paroxysmal kinesigenic dyskinesia, as a result of recently found mutations in the proline-rich transmembrane protein 2, PRRT2. Chorea can also be a major feature in other neurogenetic disorders, including the spinocerebellar ataxias and also in neurometabolic disorders.

  19. Topical review: cluster headache and sleep-related breathing disorders.

    Bender, Steven D

    2011-01-01

    This article reviews the existing literature of the common anatomic and physiologic aspects of cluster headache and sleep-related breathing disorders to point out evidence suggesting potential therapies beneficial for both maladies. A search of PubMed, as well as relevant textbooks, was conducted using the terms cluster, headache, sleep, apnea, pain, and chronobiology to find any previously published work that may connect the two disorders. Relevant references in the literature were also investigated. As a group, cluster headache patients tend to have a higher incidence of sleep-related breathing disorders as compared to the noncluster headache population. While commonalities in anatomy and physiology exist, robust evidence linking the two disorders is currently lacking. Many people are unaware that they suffer with a sleep-related breathing disorder. The high incidence of these two disorders occurring together should prompt the clinician who treats cluster headache patients to be acutely aware that a yet undiagnosed sleep disorder may also be present.

    The coincidence of tobacco smoking and psychiatric disorders is of great epidemiological and therapeutic importance. Tobacco smoking by people with mental disorders leads to disproportionately high somatic health risks, an adverse clinical course, poorer clinical outcomes and reduced quality of life (QoL). The etiological causes of the high comorbidity between smoking and mental disorders are still unclear: currently, tobacco smoking is discussed as being either the consequence or contributory cause of psychological disorders or both disorders share common antecedents and interactions. Psychiatric patients are motivated to quit and smoking cessation is not generally less effective with smokers with mental disorders than with mentally healthy individuals. Specific smoking cessation programs in the inpatient and outpatient settings are time-consuming and complex but effective. Within the framework of the current S3 guidelines the international evidence has been updated and transformed into treatment guidelines following an elaborate consensus process. Basically the same interventional measures should be used as with mentally healthy individuals; however, smokers with a psychological comorbidity often need more intensive adjuvant psychotherapeutic interventions and often need pharmaceutical support, (bupropion, varenicline and nicotine replacement therapy). Due to the overall unsatisfactory findings the treatment guidelines are partially based on clinical consensus decisions. In this field, a considerable need for research has been determined.

    2015-01-01

    The term gluten-related disorders (GRD) refers to a spectrum of diverse clinical manifestations triggered by the ingestion of gluten in genetically susceptible individuals. They include both intestinal and extraintestinal manifestations. Gluten ataxia (GA) is one of the commonest neurological manifestations of GRD. It was originally defined as otherwise idiopathic sporadic ataxia in the presence of circulating antigliadin antibodies of IgA and/or IgG type. Newer more specific serological markers have been identified but are not as yet readily available. GA has a prevalence of 15% amongst all ataxias and 40% of all idiopathic sporadic ataxias. It usually presents with gait and lower limb ataxia. It is of insidious onset with a mean age at onset of 53 years. Up to 40% of patients have evidence of enteropathy on duodenal biopsy. Gastrointestinal symptoms are seldom prominent and are not a reliable indicator for the presence of enteropathy. Furthermore, the presence of enteropathy does not influence the response to a gluten-free diet. Most patients will stabilise or improve with strict adherence to gluten-free diet depending on the duration of the ataxia prior to the treatment. Up to 60% of patients with GA have evidence of cerebellar atrophy on MR imaging, but all patients have spectroscopic abnormalities primarily affecting the vermis. Recent evidence suggests that patients with newly diagnosed coeliac disease presenting to the gastroenterologists have abnormal MR spectroscopy at presentation associated with clinical evidence of subtle cerebellar dysfunction. The advantage of early diagnosis and treatment (mean age 42 years in patients presenting with gastrointestinal symptoms vs. 53 years in patients presenting with ataxia) may protect the first group from the development and/or progression of neurological dysfunction. © 2015 S.

    A nasally applied cellulose powder is increasingly used in many countries as a remedy for allergic rhinitis. The absence of side effects makes the treatment particularly attractive in children. The efficacy in pollen allergic children, however, is not studied, nor is the relation to various pollen exposures. During the birch pollen season in 2009, a double blind, placebo-controlled study was conducted in 53 subjects, aged 8-18 yr, with allergic rhinitis attributed to birch pollen. All children were on daily oral antihistamine. Reminders and reporting of symptom scores were made by SMS on mobile phones. Pollen was collected in a volumetric trap from which figures of pollen concentrations from 1979 to 2009 were available. There was a significant reduction in total symptom scores from the nose (Placebo 7.29, Active 6.07, p = 0.033) and specifically for running nose (Placebo 2.56, Active 2.03, p = 0.017). All symptoms from the nose, eyes and lower airways were lower in the active group but reached significance only as earlier. The best effect was seen after days with low or moderate pollen counts (≤100/m(3)), the predominating pollen load over 31 yr in the area. No clinically significant adverse effects were seen. The product reduces symptoms of SAR in children and adolescents. Original data on pollen concentrations over 31 yr are presented with levels mainly in the low range favouring the observed efficacy profile. SMS communication on mobile phone for reminders and recording symptom scores was an excellent logistics tool. © 2011 John Wiley & Sons A/S.

    Congenitally or early impaired skin barrier as the first event starting the 'atopic march' in atopic dermatitis (AD) patients can increase allergen penetration that results in sensitization, even in the airways, followed by asthma and allergic rhinitis. Thymic stromal lymphopoietin (TSLP) is a cytokine existing in high levels in AD skin and is considered as a novel therapeutic target for atopic disease. We generated oxazolone (Ox)-induced AD-like (Ox-AD) hairless mice and divided them into four groups according to the therapeutic challenges: topical glucocorticoid, pimecrolimus, emollient, and control (acetone-only treated). We assessed the functional studies of skin barrier, epidermal expressions of differentiation markers, IL-1α, TNF-α, proteinase-activated receptor-2 (PAR-2), TSLP and antimicrobial peptides (AMP), and serum IgE in each group. Topical glucocorticoid or pimecrolimus treatment improved AD-like skin lesions and barrier functions, and restored the epidermal expression of differentiation markers, IL-1α, TNF-α, PAR-2, and TSLP, in Ox-AD mice. The improvement was relatively better with the glucocorticoid than pimecrolimus. Epidermal AMP expression was restored by topical glucocorticoid, but not pimecrolimus. Our result showed that topical glucocorticoid or pimecrolimus improved the AD-like skin lesions and barrier impairment by suppressing TSLP-related allergic inflammation.

    Keratoconus and other noninflammatory corneal thinning disorders (keratoglobus, pellucid marginal degeneration and posterior keratoconus) are characterized by progressive corneal thinning, protrusion and scarring; the result is distorted and decreased vision. The etiology and pathogenesis of these disorders are unknown but may be associated with a variety of factors, including contact lens wear, eye rubbing, Down's syndrome, atopic disease, connective tissue disease, tapetoretinal degeneration and inheritance. Recent advances in techniques for biochemical and pathological investigation are now allowing further exploration in these areas. Early diagnosis is aided by the finding of irregular corneal astigmatism with inferior corneal steepening. Treatment ranges from simple spectacle correction to keratoplasty. In this review, the past and present literature on corneal thinning disorders is reviewed and practical approaches to diagnosis and management are outlined.

    Synopsis Youth affected by obsessive compulsive disorder (OCD) and by chronic tic disorders (CTDs) often experience significant distress, functional impairment, and psychiatric comorbidity which collectively compromise quality of life and achievement of developmental milestones. We review the extant literature on the phenomenology and treatment of these conditions in youth, and summarize the state of the treatment literature, focusing particularly on the application of psychosocial interventions that have yielded substantial symptom improvements. Comorbidity of OCD and CTDs is common, and we provide clinical recommendations for managing patients when both disorders are present. We conclude with a brief discussion of clinical controversies, particularly the central role ascribed to habituation as the mechanism by which these treatments' effects are realized. PMID:22800994

Response-locked ERPs contained a frontocentral ERN and posterior Pe. Error-related Negativity and Positivity exhibited larger amplitude and later latency than corresponding waves for correct responses matched on reaction time. ADHD did not affect performance on the task. The ADHD/Combined sample exceeded controls in ERN amplitude, perhaps reflecting patients’ adaptive monitoring efforts. Compared with controls, subjects with Reading Disorder and Reading+Math Disorder performed worse on the task and had marginally more negative Correct-Related Negativities. In contrast, Pe/Pc was smaller in children with Reading+Math Disorder than among subjects with Reading Disorder and Not-LD participants; this nonspecific finding is not attributable to error processing. The results reflect anomalies in error processing in these disorders but further research is needed to address inconsistencies in the literature. PMID:17257731

    It has been shown that sleep-related breathing disorders, especially sleep apnea, are very common in patients who have had a stroke, and that they also reduce the potential for neurological recovery. Nevertheless, other sleep disorders caused by stroke (excessive daytime sleepiness, insomnia, sleep related movement disorders) can also cause or increase stroke-related disability, and this fact is less commonly known. Studies with polysomnography have shown many abnormalities in sleep architecture during the acute phase of stroke; these abnormalities have a negative impact on the patient's quality of life although they tend to improve with time. This also happens with other sleep disorders occurring as the result of a stroke (insomnia, narcolepsy, restless legs syndrome, periodic limb movement disorder and REM sleep behavior disorder), which are nevertheless potentially treatable. In this article, we briefly review the physiopathology and epidemiology of the disorders listed above in order to raise awareness about the importance of these disorders and the effects they elicit in stroke patients. Sleep disorders that are not breathing-related have scarcely been studied in stroke patients despite the fact that almost all such disorders may present as a result of a cerebrovascular event.

    Several studies have reported negative relations between allergic diseases and school performance but have not simultaneously considered various allergic diseases, including allergic rhinitis, asthma, and atopic dermatitis, and only examined a limited number of participants. The present study investigated the associations of allergic rhinitis, asthma, and atopic dermatitis with school performance in a large, representative Korean adolescent population. A total of 299,695 7th through 12th grade students participated in the Korea Youth Risk Behaviour Web-based Survey (KYRBWS) from 2009 to 2013. The subjects’ history of allergic rhinitis, asthma, and atopic dermatitis and number of school absences due to these diseases in the previous 12 months were examined and compared. School performance was classified into 5 levels. The relations between allergic disorders and school performance were analyzed using multiple logistic regressions with complex sampling and adjusted for the subjects’ durations of sleep, days of physical activity, body mass indexes (BMIs), regions of residence, economic levels, parents’ education levels, stress levels, smoking status, and alcohol use. A subgroup analysis of the economic groups was performed. Allergic rhinitis was positively correlated with better school performance in a dose-dependent manner (adjusted odds ratios, AOR, [95% confidence interval, CI] = 1.50 [1.43–1.56 > 1.33 [1.28–1.38] > 1.17 [1.13–1.22] > 1.09 [1.05–1.14] for grades A > B > C > D; P < 0.001).

    Concepts of disease severity, activity, control and responsiveness to treatment are linked but different. Severity refers to the loss of function of the organs induced by the disease process or to the occurrence of severe acute exacerbations. Severity may vary over time and needs regular follow-up. Control is the degree to which therapy goals are currently met. These concepts have evolved over time for asthma in guidelines, task forces or consensus meetings. The aim of this paper is to generalize the approach of the uniform definition of severe asthma presented to WHO for chronic allergic and associated diseases (rhinitis, chronic rhinosinusitis, chronic urticaria and atopic dermatitis) in order to have a uniform definition of severity, control and risk, usable in most situations. It is based on the appropriate diagnosis, availability and accessibility of treatments, treatment responsiveness and associated factors such as comorbidities and risk factors. This uniform definition will allow a better definition of the phenotypes of severe allergic (and related) diseases for clinical practice, research (including epidemiology), public health purposes, education and the discovery of novel therapies.

  18. Allergic diseases in the elderly

    PubMed Central

    2011-01-01

    Demographic distribution of the population is progressively changing with the proportion of elderly persons increasing in most societies. This entails that there is a need to evaluate the impact of common diseases, such as asthma and other allergic conditions, in this age segment. Frailty, comorbidities and polymedication are some of the factors that condition management in geriatric patients. The objective of this review is to highlight the characteristics of allergic diseases in older age groups, from the influence of immunosenescence, to particular clinical implications and management issues, such as drug interactions or age-related side effects.

    2014-06-01

    Hereditary porphyrias comprise a group of eight metabolic disorders of the haem biosynthesis pathway, characterised by acute neurovisceral symptoms and/or skin lesions. Each porphyria is caused by abnormal functioning of a particular enzymatic step, resulting in specific accumulation of heme precursors. Seven porphyrias are due to a partial enzyme deficiency, while a gain-of-function mechanism has recently been identify in a novel porphyria. Acute porphyrias present with severe abdominal pain, nausea, constipation and confusion, and are sometimes complicated by seizures and severe neurological disorders, which may be life-threatening. Cutaneous porphyrias can also be present, with either acute painful photosensitivity or skin fragility and blisters. Rare recessive porphyrias usually manifest in early childhood with either severe chronic neurological symptoms or chronic haemolysis and severe cutaneous photosensitivity. Porphyrias are still under-diagnosed, but recent advances in the pathogenesis and genetics of human porphyrias are leading to better care of these patients and their families.

  20. Climate change and allergic disease.

    Climate change is potentially the largest global threat to human health ever encountered. The earth is warming, the warming is accelerating, and human actions are largely responsible. If current emissions and land use trends continue unchecked, the next generations will face more injury, disease, and death related to natural disasters and heat waves, higher rates of climate-related infections, and wide-spread malnutrition, as well as more allergic and air pollution-related morbidity and mortality. This review highlights links between global climate change and anticipated increases in prevalence and severity of asthma and related allergic disease mediated through worsening ambient air pollution and altered local and regional pollen production. The pattern of change will vary regionally depending on latitude, altitude, rainfall and storms, land-use patterns, urbanization, transportation, and energy production. The magnitude of climate change and related increases in allergic disease will be affected by how aggressively greenhouse gas mitigation strategies are pursued, but at best an average warming of 1 to 2 degrees C is certain this century. Thus, anticipation of a higher allergic disease burden will affect clinical practice as well as public health planning. A number of practical primary and secondary prevention strategies are suggested at the end of the review to assist in meeting this unprecedented public health challenge.

  1. Cutaneous EBV-related lymphoproliferative disorders.

    2017-01-01

    This article will focus on the cutaneous lymphoproliferative disorders associated with EBV, with an emphasis on the upcoming changes in the revised 4th Edition of the WHO classification of tumors of the hematopoietic system, many of which deal with cutaneous disorders derived from NK-cells or T-cells. Extranodal NK/T-cell lymphoma usually presents in the upper aerodigestive tract, but can involve the skin secondarily. EBV-associated T- and NK-cell lymphoproliferative disorders (LPD) in the pediatric age group include the systemic diseases, chronic active EBV infection (CAEBV) and systemic EBV+ T-cell lymphoma of childhood. Hydroa vacciniforme (HV)-like LPD is a primarily cutaneous form of CAEBV and encompasses the lesions previously referred to as HV and HV-like lymphoma (HVLL). All the T/NK-cell-EBV-associated diseases occur with higher frequency in Asians, and indigenous populations from Central and South America and Mexico. Among the B-cell EBV-associated LPD two major changes have been introduced in the WHO. The previously designated EBV-positive diffuse large B-cell lymphoma (EBV-DLBCL) of the elderly, has been changed to EBV-DLBCL with 'not otherwise specified' as a modifier (NOS). A new addition to the WHO system is the more recently identified EBV+ mucocutaneous ulcer, which involves skin and mucosal-associated sites.

    Reporting two of our cases we wanted to point to a great dilemma related to the final diagnosis. Recently, such cases have been more frewuently seen, since in all patients with allergic rhinitis conditions of the lower airways is examined before the administration of the specific immunotherapy. Therefore, we may see patients who are still free of pulmonary sings, despite of positive specific and/or non specific bronchoprovocative tests. The presented cases with evidenced allergic rhinitis are probably in the phase of development of allergic bronchial asthma, the phase of "allergic inflammation" of the lower airways, not clinically manifested yet.

  3. Unique contributions of individual eating disorder symptoms to eating disorder-related impairment.

    2015-08-01

    This study examined the unique contribution of individual eating disorder symptoms and related features to overall eating disorder-related impairment. Participants (N=113) from the community with eating disorders completed assessments including the Clinical Impairment Assessment (CIA) and the Eating Disorder Examination Questionnaire. A multiple linear regression analysis indicated that 58.6% of variance in the CIA was accounted for by binge eating frequency, weight and shape concerns, and depression. These findings indicate that certain eating disorder symptoms uniquely account for impairment and that depression is a substantial contributor. It is possible that purging, restrictive eating, and body mass index did not significantly contribute to impairment because these features are consistent with many individuals' weight and shape goals. The results imply that eating disorder-related impairment may be more a result of cognitive features and binge eating rather than body weight and compensatory behaviors.

    Attention-deficit hyperactivity disorder (ADHD) is associated with bipolar disorder and schizophrenia, and it has been suggested that combined bipolar disorder and ADHD is aetiologically distinct from the pure disorders. To clarify whether ADHD shares genetic and environmental factors with bipolar disorder and schizophrenia. By linking longitudinal Swedish national registers, we identified 61 187 persons with ADHD (the proband group) and their first- and second-degree relatives, and matched them with a control group of people without ADHD and their corresponding relatives. Conditional logistic regression was used to determine the risks of bipolar disorder and schizophrenia in the relatives of the two groups. First-degree relatives of the ADHD proband group were at increased risk of both bipolar disorder (odds ratio (OR) = 1.84-2.54 for parents, offspring and full siblings) and schizophrenia (OR = 1.71-2.22 for parents, offspring and full siblings). The risks of bipolar disorder and schizophrenia among second-degree relatives were substantially lower than among full siblings. These findings suggest that the co-occurrence of ADHD and bipolar disorder as well as ADHD and schizophrenia is due to shared genetic factors, rather than representing completely aetiologically distinct subsyndromes.

    2017-08-01

    Myofascial pelvic pain refers to pain in the pelvic floor muscles, the pelvic floor connective tissue, and the surrounding fascia. The cause is often multifactorial and requires treatment that encompasses multiple modalities. This type of pain is often associated with other abdominopelvic disorders, so providers in these specialties need to be aware of these connections. A comprehensive musculoskeletal examination, including evaluation of the pelvic floor muscles, and history are key to diagnosing myofascial pelvic pain. Treatments include physical therapy, muscle relaxers, oral neuromodulators, cognitive-behavioral therapy, and pelvic floor muscle injections. Copyright © 2017 Elsevier Inc. All rights reserved.

    Mental disorders are common in our industrialised society and inevitably affect the working population. Over the last few years greater attention has been focussed on work-related psychopathologies due to an increasing number of studies regarding workplace bullying. This study reports our observations on patients with mental disorders who came to our Occupational Health Centre because they perceived themselves to be victims of negative working conditions. An indepth analysis of their working conditions led us to the conclusion that many of these disorders were to be attributed to the workplace. Between 2004 and 2010, 449 workers attended our Occupational Health Centre, most suffering from mental disorders which they ascribed to negative working conditions. All patients had an initial consultation session with an occupational physician which focused on the environmental and relational characteristics of their place of work. Thereafter, patients underwent a second clinical evaluation with a psychologist including several psychological tests. At the end of diagnostic process, the occupational physician and the clinical psychologist drew their clinical conclusions and defined the possible relationship with the working condition. For 379 out of 449 patients/workers, a positive and causal relationship between medical disorders and working conditions was established. The mental disorders observed in these groups of workers were: mixed anxiety and depressive disorder (53.6%), depressive disorder (16.2%), adaptation disorder (15.9%), anxiety disorder (13%) and only 1.3% post-traumatic stress disorder. The working conditions favouring the mental disorders were: workplace bullying, such as person-related bullying (30.1%) and task-related bullying (14.8%), adverse situations causing work distress (38.2%) or non-specific work discomfort (16,9%). Our experience showed that not only workplace bullying can cause different psychiatric disorders but also adverse situations that

    There is a considerable variation in the prevalence of allergic disorders in developing countries. These differences may be attributable to different methodological problems and to the lack of operational definitions. Several studies suggest that the prevalence of allergic diseases has been increasing worldwide in recent years. However, in Mexico, there is no data in open population. To know in open population the prevalence of allergic diseases in the counties of Mexico City, the frequence of symptoms in each allergic disease, the therapeutic modalities that patients seek, the school and work annual absences and the amount of money that each patient spends in antiallergic drugs. It was an open-population, cross-sectional trial, in two phases with a random sample size of 8,000 individuals from 214 public health centers. Statistical analysis was made with Excel 97-2004: Mann-Whitney U test for continuous variables and chi-square-test for discrete variables, p < 0.05 was considered statistically significant. The prevalence of allergic diseases in Mexico City was 42.6%, allergic rhinitis was the most frequent. Children are the largest age group affected. The highest prevalence was found in Tlahuac county. Coexistence of allergic diseases was found in 19.9%. The 44.2% of allergic patients attended to their general practitioner. 20.4% of all patients spent 10-20% of their income in medicines and 26% do not have money to buy antiallergic drugs. School and work annual absences are 3.37 +/- 3.86 and 6.2 +/- 12.84 days, respectively. Allergic diseases must be considered a public-health problem in Mexico City.

    We assessed the relation between season of birth and eating disorder symptoms and personality characteristics in a sample of 880 women with eating disorders and 580 controls from two Price Foundation Studies. Eating disorder symptoms were assessed using the Structured Interview of Anorexic and Bulimic Disorders and the Structured Clinical Interview for DSM-IV. Personality traits were assessed using the Temperament and Character Inventory and the Frost Multidimensional Perfectionism Scale. Date of birth was obtained from a sociodemographic questionnaire. No significant differences were observed 1) in season of birth across eating disorder subtypes and controls; nor 2) for any clinical or personality variables and season of birth. We found no evidence of season of birth variation in eating disorders symptoms or personality traits. Contributing to previous conflicting findings, the present results do not support a season of birth hypothesis for eating disorders.

    Substance abuse cessation is one of the leading factors in determining the eligibility for the heart transplantation waiting list, as noncompliance with this issue may seriously endanger posttransplantation outcomes. Yet, the prevalence of substance-related disorders among candidates for heart transplantation has not been evaluated enough. Eighty three heart transplantation candidates were assessed for prior or current substance-related disorders through the Structured Clinical Interview for mental disorders according to DSM-IV. A prior history of at least one substance-related disorder was found in 64% of patients, with nicotine dependence as the most prevalent diagnosis (61.4% of the sample). Ten subjects were currently smokers, despite heart failure. A prior history of alcohol abuse and caffeine intoxication was found in 9.6% and 2.4% of patients, respectively. Substance abuse or dependence behaviors should be monitored during all the phases of heart transplantation program. Early identification of current substance-related disorders may allow better allocation of organ resources and proper lifestyle modification programs provision. A prior history of substance-related disorders should alert physicians to assess patients for possible relapse, especially after transplantation. The inclusion of a specialist in the assessment and treatment of substance-related disorders in the heart transplantation unit may reduce the risk of unsuccessful outcomes due to noncompliance with an adequate lifestyle.

    2004-01-01

    Family history studies of autism consistently reveal a large subgroup with a high incidence of major mood disorder in family members, suggesting the two entities are related clinically and genetically. This review examines this concept, comparing current clinlical and biological knowledge of autism and major mood disorder, and advances the hypothesis that this subgroup of autism represents an early-life phenotype of major mood disorder. If confirmed, this hypothesis would suggest that the basic biological defects determining major mood disorders may have prominent neurodevelopmental and cognitive dimensions. Testing of the hypothesis will depend on genetic studies.

    Indoor and outdoor fungal exposure has been shown to be associated with the development of allergic respiratory diseases. The aim of the study was to investigate the types and concentrations of airborne fungi inside and outside homes and evaluate the association between fungal levels and allergic diseases in the southern region of Turkey. A total of 61 children admitted with respiratory complaints to the pediatric allergy clinic between September 2007 and November 2008 were included in this study. The air samples were obtained using the Air IDEAL volumetric air sampler longitudinally for 1 year. A comprehensive questionnaire was used for medical history and housing conditions. Skin prick test was performed to determine fungal sensitivity and spirometric indices were employed. The predominant indoor fungal species were Cladosporium (69.3 %), Penicillium (18.9 %), Aspergillus (6.5 %), and Alternaria (3.1 %). A strong correlation between indoor and outdoor fungal levels was detected for the Cladosporium species (p < 0.001, r = 0.72) throughout the year. Living in a detached home (p = 0.036) and the presence of cockroaches (p = 0.005) were associated with total indoor fungal levels. The presence of cockroaches (aOR 3.5; 95 % CI 0.95-13.10, p = 0.059) was also associated with fungal sensitization at the edge of significance. The statistical cutoff values of indoor and outdoor Cladosporium levels to predict symptomatic asthma were found to be >176 CFU/m(3) (p = 0.003, AUC 0.696; sensitivity 65.5 %; specificity 68.7 %) and >327 CFU/m(3) (p = 0.038; AUC 0.713; sensitivity 66.6 %; specificity 76.9 %), respectively. Children with respiratory symptoms are exposed to a considerable level of fungi inside and outside their homes. The prevention of fungal exposure may provide valuable intervention for respiratory diseases.

    Changes in the human microbiome have been suggested as a risk factor for a number of lifestyle-related disorders, such as atopic diseases, possibly through a modifying influence on immune maturation in infancy. We aimed to explore the association between neonatal fecal flora and the development of atopic disorders until age 6 years, hypothesizing that the diversity of the intestinal microbiota influences disease development. We studied the intestinal microbiota in infants in the Copenhagen Prospective Study on Asthma in Childhood, a clinical study of a birth cohort of 411 high-risk children followed for 6 years by clinical assessments at 6-month intervals, as well as at acute symptom exacerbations. Bacterial flora was analyzed at 1 and 12 months of age by using molecular techniques based on 16S rRNA PCR combined with denaturing gradient gel electrophoresis, as well as conventional culturing. The main outcome measures were the development of allergic sensitization (skin test and specific serum IgE), allergic rhinitis, peripheral blood eosinophil counts, asthma, and atopic dermatitis during the first 6 years of life. We found that bacterial diversity in the early intestinal flora 1 and 12 months after birth was inversely associated with the risk of allergic sensitization (serum specific IgE P = .003; skin prick test P = .017), peripheral blood eosinophils (P = .034), and allergic rhinitis (P = .007). There was no association with the development of asthma or atopic dermatitis. Reduced bacterial diversity of the infant's intestinal flora was associated with increased risk of allergic sensitization, allergic rhinitis, and peripheral blood eosinophilia, but not asthma or atopic dermatitis, in the first 6 years of life. These results support the general hypothesis that an imbalance in the intestinal microbiome is influencing the development of lifestyle-related disorders, such as allergic disease.

    Sleep related disorders are common and under-recognized in the chronic obstructive pulmonary disease (COPD) population. COPD symptoms can disrupt sleep. Similarly, sleep disorders can affect COPD. This review highlights the common sleep disorders seen in COPD patients, their impact, and potential management. Treatment of sleep disorders may improve quality of life in COPD patients. Optimizing inhaler therapy improves sleep quality. Increased inflammatory markers are noted in patients with the overlap syndrome of COPD and obstructive sleep apnea versus COPD alone. There are potential benefits of noninvasive positive pressure ventilation therapy for overlap syndrome patients with hypercapnia. Nocturnal supplemental oxygen may be beneficial in certain COPD subtypes. Nonbenzodiazepine hypnotic therapy for insomnia has shown benefit without associated respiratory failure or worsening respiratory symptoms. Melatonin may provide mild hypnotic and antioxidant benefits. This article discusses the impact of sleep disorders on COPD patients and the potential benefits of managing sleep disorders on respiratory disease control and quality of life.

    Business and tourist journeys by air contribute to exposure of the body to multiple environments. The allergic patient, considered rightly to be a sentry of the environment, has many reasons to care about his journeys and to take precautions that are adapted to his case under the impetus of advice and information from his physician and his specialist. Some advice falls within a simple logic that is enough to remember when planning the journey while the others measures must follow a correct preventative strategy for allergy risks as much as those that concern the modalities before leaving as a drive taken on the ground. It is important therefore to know how to give advice and information on the different risks linked to the allergic condition and to the field of allergy and help the patient to orientate his choice of place of the journey, the methods of lodging, of transport and the programme of the journey. The advice should also include the preventative measures as a function of the known pathology under the form of medical equipment before, during the stay and on return. Finally some advice relative to medical equipment for prevention and cure would appear to be judicious.

    Marfan syndrome is an autosomal dominantly inherited connective tissue disorder with a prevalence of approximately 1:5000 people. Typical manifestations affect the cardiovascular system, eyes, skeleton, lungs, skin and dura mater. Most patients have a so-called marfanoid habitus with tall stature, long and narrow limbs, a long and narrow head shape and other skeletal abnormalities. Of particular medical importance are the possible complications such as severe scoliosis or pectus excavatum, spontaneous pneumothorax, retinal detachment, or an acute glaucoma evoked by lens luxation. However, the most dangerous complication is acute dissection of the ascending aorta, which is usually the result of a slowly progressive aortic dilatation. With the introduction of therapies the average life expectancy of previously just 32 years could be raised to above 60 years.

    2014-01-01

    Eosinophilic gastroenteritis (EGE) represents one member within the spectrum of diseases collectively referred to as eosinophilic gastrointestinal disorders (EGIDs), which includes eosinophilic esophagitis (EoE), gastritis, enteritis, and colitis. EGE is less common than EoE and involves a different site of disease, but otherwise shares many common features with EoE. The clinical manifestations of EGE are protean and can vary from nausea and vomiting to protein losing enteropathy or even bowel obstruction requiring surgery. Although systemic corticosteroids are an effective treatment for EGE, their use over the chronic course of the disease results in substantial corticosteroid toxicity. Accordingly, there is a great need for improved therapies for these patients. PMID:24813518

    2016-05-01

    Despite developments in panic disorder (PD) research, a significant percentage of patients do not benefit from conventional treatments. Interpersonal factors have been identified as potential predictors of treatment failures. We aimed to evaluate assertiveness in a sample of patients with PD and its implications for treatment. Forty-six symptomatic patients with PD and 46 college students responded to assessment scales regarding assertiveness and clinical data. Seventy-five percent of the patients had a secondary diagnosis of agoraphobia. We found that the PD group was characterized as nonassertive and slightly less assertive than control subjects. Furthermore, the deficit in the level of assertiveness correlated with the severity of the PD. The diagnosis of agoraphobia was correlated with unassertiveness (p < 0.05). Agoraphobia predisposes individuals to dependency and insecurity about their ability to overcome anxiogenic situations. These data demonstrate the importance of managing assertiveness in patients with PD accompanied by agoraphobia.

Mediators of inflammation modulate sleep , with Th1 cytokines promoting NREM sleep and increasing sleepiness and Th2 cytokines (produced during allergic inflammation) impairing sleep. As sleep impairment is a rapidly modifiable suicide risk factor strongly associated with mood disorders, we review the literature leading to the hypothesis that allergic rhinitis leads to mood and anxiety disorders and an increased risk of suicide via sleep impairment. Specifically, allergic rhinitis can impair sleep through mechanical (obstructive) and molecular (cytokine production) processes. The high prevalence of mood and anxiety disorders and allergy, the nonabating suicide incidence, the currently available treatment modalities to treat sleep impairment and the need for novel therapeutic targets for mood and anxiety disorders, justify multilevel efforts to explore disturbance of sleep as a pathophysiological link.

    Objectives. We examined lifetime and 12-month rates of any depressive, anxiety, and substance abuse disorders in a national sample of Asian Americans. We focused on factors related to nativity and immigration as possible correlates of mental disorders. Methods. Data were derived from the National Latino and Asian American Study, the first national epidemiological survey of Asian Americans in the United States. Results. The relationships between immigration-related factors and mental disorders were different for men and women. Among women, nativity was strongly associated with lifetime disorders, with immigrant women having lower rates of most disorders compared with US-born women. Conversely, English proficiency was associated with mental disorders for Asian men. Asian men who spoke English proficiently generally had lower rates of lifetime and 12-month disorders compared with nonproficient speakers. Conclusions. For Asian Americans, immigration-related factors were associated with mental disorders, but in different ways for men and women. Future studies will need to examine gender as an important factor in specifying the association between immigration and mental health. PMID:17138908

    Obstructive sleep apnea and central sleep apnea are burgeoning sleep-related breathing disorders within the general population. Most of the associated comorbidities and causes of these sleep disorders are known to negatively impact cardiorespiratory fitness; however, little is known about the direct relationships between cardiorespiratory fitness, obstructive sleep apnea and central sleep apnea. This article provides a systematic analysis of existing peer reviewed, published clinical studies pertaining to the relationship between cardiorespiratory fitness and sleep-related breathing disorders in adults. A brief description of each sleep disorder, the pathophysiology, its epidemiology and its implications for cardiorespiratory fitness are provided. Finally, we discuss therapy for each disorder and its effect on the cardiovascular system.

Medline database from January 1966 to December 2013, Cochrane database and clinicaltrials.gov. We used keywords topiramate, addiction, substance abuse, alcohol, tobacco, nicotine, cocaine, methamphetamine, opiate, heroin, benzodiazepine, cannabis, bulimia nervosa, binge eating disorder, gambling. All clinical trials were included. Animal trials, laboratory tests, reviews, answers to writers, case-reports, case series and publications unrelated to the topic were excluded. Twenty-eight articles investigating the efficacy of topiramate in substance use were included. In alcohol-related disorder, several trials and a meta-analysis showed a reduction of days of consumption. In a single-center trial on tobacco-related disorder, topiramate was not found effective in reducing the carbon monoxide expired. In cocaine-related disorder, one single-center trial showed a reduction of days of consumption and two single-center trials have found a trend in favour of topiramate. In alcohol and cocaine co-dependency, a single-center trial found a trend in favour of topiramate. In methamphetamine-related disorder, a multicenter trial found a trend in favour of topiramate. In bulimia nervosa, two single-center trials showed a reduction in binge eating and compensatory behaviours. In binge eating disorder, several trials showed a reduction of binge eating and weight. In gambling, one single-center trial did not show any significant results. There were no randomized controlled trials found in opioid-related disorder, benzodiazepines-related disorder, and cannabis-related disorder. Definition of abstinence and methods to assess the efficacy of topiramate differed between trials. The methodological quality of included trials was variable, especially with no double-blind procedure in eight trials. Topiramate showed

    Rhinitis is a global problem and is defined as the presence of at least one of the following: congestion, rhinorrhea, sneezing, nasal itching, and nasal obstruction. The two major classifications are allergic and nonallergic rhinitis (NAR). Allergic rhinitis occurs when an allergen is the trigger for the nasal symptoms. NAR is when obstruction and rhinorrhea occurs in relation to nonallergic, noninfectious triggers such as change in the weather, exposure to caustic odors or cigarette smoke, barometric pressure differences, etc. There is a lack of concomitant allergic disease, determined by negative skin prick test for relevant allergens and/or negative allergen-specific antibody tests. Both are highly prevalent diseases that have a significant economic burden on society and negative impact on patient quality of life. Treatment of allergic rhinitis includes allergen avoidance, antihistamines (oral and intranasal), intranasal corticosteroids, intranasal cromones, leukotriene receptor antagonists, and immunotherapy. Occasional systemic corticosteroids and decongestants (oral and topical) are also used. NAR has 8 major subtypes which includes nonallergic rhinopathy (previously known as vasomotor rhinitis), nonallergic rhinitis with eosinophilia, atrophic rhinitis, senile rhinitis, gustatory rhinitis, drug-induced rhinitis, hormonal-induced rhinitis, and cerebral spinal fluid leak. The mainstay of treatment for NAR are intranasal corticosteroids. Topical antihistamines have also been found to be efficacious. Topical anticholinergics such as ipratropium bromide (0.03%) nasal spray are effective in treating rhinorrhea symptoms. Adjunct therapy includes decongestants and nasal saline. Investigational therapies in the treatment of NAR discussed include capsaicin, silver nitrate, and acupuncture. PMID:21738880

    Aims To identify the incidence of allergic conjunctivitis in patients with allergic rhinitis. Methods One hundred and eighty seven consecutive patients with allergic rhinitis (AR) were directly questioned if they have allergic conjunctivitis (AC) and this was clarified using standard screening questions relating to red, itchy and watery eyes recorded through a total ocular symptom score (TOSS). Patients were also asked about further symptoms that may be attributable to AC: eyelid dermatitis, frequent blinking; eye sensitivity and frontal headache from squinting or. blinking. All patients were given a drop of olopatadine hydrochloride 0.1% in each eye to help identify “silent” disease. 20 healthy non-atopic controls were also treated with olopatadine drops and questioned on ocular symptoms. Results Fifty five percent of patients with AR were identified as having AC by direct questioning and the use of the TOSS questionaire. A further 41% were identifiable by asking additional questions and performing therapeutic challenge with olopadatine. Conclusions AC is a frequent comorbid condition occurring in 95% of our patients with AR. Only 55% of patients were able to identify that they had AC based on standard screening questions. Additional specific questioning and a therapeutic challenge in suspected patients can help identify patients who may benefit from treatment of AC. PMID:23663473

    This paper concerns the revised classification of Substance-Related and Addictive Disorders in the fifth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5). In DSM-5, substance use disorders are diagnosed on a continuum of severity specified by explicit operationalized diagnostic criteria. "Gambling disorder" is the only behavioral addiction added to the DSM. Furthermore, preliminary criteria for "Caffeine Use Disorder" and "Internet Gaming Disorder" have now been defined in the manual. Adopting the DSM-5 criteria catalogue within the German treatment system for children and adolescents with substance use disorders or at risk for developing substance use disorders would be of great significance. Since the diagnostic threshold is lower, more patients would be eligible for treatment. Thus, early intervention in the area of substance use disorders should be strengthened, a development that appears to be highly desirable from the perspective of child and adolescent psychiatry. The current Section III diagnoses, with their now comprehensive diagnostic criteria, facilitate more internationally compatible research.

    2009-01-01

    Anxiety disorders are the most common psychiatric illnesses in the U.S. with approximately 30% of the population experiencing anxiety-related symptoms in their lifetime (Kessler et al., 2005). Notably, a variety of studies have demonstrated that 30−40% of the variance contributing to these disorders is heritable. In the present review, we discuss the latest findings regarding the genetic and environmental influences on the development and symptomatology of anxiety disorders. Specific emphasis is placed on posttraumatic stress disorder (PTSD) due to its uniqueness as an anxiety disorder; its diagnosis is dependent on a precipitating traumatic event and its development appears to be mediated by both genetic and environmental contributions. The co-morbidity of anxiety disorders and the potential reclassification of anxiety disorders as part of DSM-V are reviewed given the potential impact on the interpretation and design of genetic investigations. Lastly, several keys to future genetic studies are highlighted. Thorough analyses of the gene by environment (GxE) interactions that govern one's vulnerability to anxiety disorder(s), the effectiveness of individual treatment strategies, and the severity of symptoms may lead to more effective prophylactic (e.g., social support) and treatment strategies.

    Substance related disorders are more prevalent in emergency services than in the general population, about 20% of individuals in emergency care test positive for alcohol. Emergency services are strategic places to identify alcohol misuse. Attitudes to individuals presenting substance related disorders are important in developing therapeutic relationships and applying interventions. This study explores the attitudes of an emergency staff to these individuals across a range of roles, and evolution in face of an addictology care improvement. Data were gathered from an emergency service sample from the emergency department of a general hospital in Morlaix (France). We used a short questionnaire, adapted from previous similar French studies. Twenty-five persons answered the first questionnaire and 18 the second. A self-administrated attitudes questionnaire showed its interest in our study and helped us to identify attitudes and to initiate a reflection on behaviours in emergency care. Moreover, it helped to change attitudes towards individuals presenting substance related disorders. The daily setting of an addictive disorders specialized unit in emergency changed the point of view on addictive disorders of both physicians and nurses. We showed differences in addictive related disorders prevalence perception among patients attending emergency care between the two evaluations. But we also showed that physicians and nurses stressed that it was more difficult to ask patients in emergency care on the second evaluation, after and despite a daily addictive disorders specialized setting. We showed several limits in emergency staff care relationship with patients with substance related disorders. They identified difficulties to talk about addictive disorders, especially in younger and older patients. Regarding literature, we discuss our study limits and different ways of improving addictology care in emergency services. Copyright © 2015 L'Encéphale, Paris. Published by

    2016-01-01

    Research into the causes of psychopathology has largely focused on two broad etiologic factors: genetic vulnerability and environmental stressors. An important role for familial/heritable factors in the etiology of a broad range of psychiatric disorders was established well before the modern era of genomic research. This review focuses on the genetic basis of three disorder categories-posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and the anxiety disorders-for which environmental stressors and stress responses are understood to be central to pathogenesis. Each of these disorders aggregates in families and is moderately heritable. More recently, molecular genetic approaches, including genome-wide studies of genetic variation, have been applied to identify specific risk variants. In this review, I summarize evidence for genetic contributions to PTSD, MDD, and the anxiety disorders including genetic epidemiology, the role of common genetic variation, the role of rare and structural variation, and the role of gene-environment interaction. Available data suggest that stress-related disorders are highly complex and polygenic and, despite substantial progress in other areas of psychiatric genetics, few risk loci have been identified for these disorders. Progress in this area will likely require analysis of much larger sample sizes than have been reported to date. The phenotypic complexity and genetic overlap among these disorders present further challenges. The review concludes with a discussion of prospects for clinical translation of genetic findings and future directions for research.

    Marfan syndrome (MFS), a relatively common autosomal dominant hereditary disorder of connective tissue with prominent manifestations in the skeletal, ocular, and cardiovascular systems, is caused by mutations in the gene for fibrillin‐1 (FBN1). The leading cause of premature death in untreated individuals with MFS is acute aortic dissection, which often follows a period of progressive dilatation of the ascending aorta. Recent research on the molecular physiology of fibrillin and the pathophysiology of MFS and related disorders has changed our understanding of this disorder by demonstrating changes in growth factor signalling and in matrix‐cell interactions. The purpose of this review is to provide a comprehensive overview of recent advances in the molecular biology of fibrillin and fibrillin‐rich microfibrils. Mutations in FBN1 and other genes found in MFS and related disorders will be discussed, and novel concepts concerning the complex and multiple mechanisms of the pathogenesis of MFS will be explained.

    To develop a framework for evaluating the work related musculoskeletal disorders (WRMSDs). The proposed framework was tested on 15~jewellery manufacturing workers working at Chinchpokhli region in Mumbai, India and on 15 students studying in a management institute of Mumbai, India. The framework has been broken into three phases. Phase 1--Ergonomic-risk evaluation; Phase 2--Musculoskeletal Disorders (MSD) evaluation and Phase 3--Clinical examination. Ergonomic-risk evaluation determines the relationship between work relatedness and musculoskeletal disorders. Musculoskeletal Disorders (MSD) evaluation tries to assess the presence of discomforts/disabilities in different body regions, through subjective evaluation tools. Ergonomic-risk evaluation involved QEC, PLIBEL and posture analysis by RULA. Musculoskeletal Disorders (MSD) evaluation involved administration of self reported questionnaires. Clinical examination involved muscle grading by a physiotherapist and back strength measurement. The framework suggested that ergonomic risk evaluation techniques, self reported body part questionnaires and physical measurement of physiological/biomechanical transients may have a relationship and can be used for the evaluation of work related musculoskeletal disorders. The proposed integrative approach will help in developing stage wise intervention strategies for work related musculoskeletal disorders.

    2015-12-01

    Dual diagnosis of schizophrenia and substance-related disorders is common in psychiatric practice. Epidemiologic studies and report have established that the risk of a substance-related disorder was 4 to 5 times higher in a population of psychiatric patients than in the general population. However, little is known on the reason of this relationship and the treatments required. It's well known that a family history of psychosis is a risk factor of schizophrenia. Similarly a family history of substance use disorders increases the risk of using substances. Because the two disorders often occurred together, it could be hypothesized that a genetic risk factor is common. However, recent studies did not confirm this hypothesis and it seems that their genetic risks factor would be unrelated. Evidence now exists describing the different profiles of patients whether they used substance or not. Concerning negative symptoms clinical studies and meta-analyses have described fewer symptoms in schizophrenia patients with a substance use disorder. Among the different explanations that have been addressed, it seems that a lower capability of obtaining the substance could partly explain this relationship. Perhaps because patients with social withdrawal have more difficulties to find and spend the time required to obtain abused substances. At the opposite some products such as cocaine may relieve some symptoms especially anhedonia and alogia. However the link between substance-related disorders and negative symptoms is weak and decreases in more recent studies, probably because negative symptoms as well as addiction disorders are better characterized. Considering that treating psychiatric symptoms may not always lead to a decrease in the substance-related disorders but that patients who give up substances improve their psychotic symptoms, a therapeutic strategy should be planned for these dual disorders patients combining psychiatry and addiction interventions.

    Preeclampsia, hemorrhage, and infection are the leading causes of maternal death in underdeveloped countries. Since several proteins associated with preeclampsia are known, we conducted a computational study which evaluated the commonness and potential functionality of intrinsic disorder of these proteins and also made an attempt to characterize their origin. The origin of the preeclampsia-related proteins was assessed with a supervised technique, a Polarity Index Method (PIM), which evaluates the electronegativity of proteins based solely on their sequence. The commonness of intrinsic disorder was evaluated using several disorder predictors from the PONDR family, the charge-hydropathy plot (CH-plot) and cumulative distribution function (CDF) analyses, and using the MobiDB web-based tool, whereas potential functionality of intrinsic disorder was studied with the D2P2 resource and ANCHOR predictor of disorder-based binding sites, and the STRING tool was used to build the interactivity networks of the preeclampsia-related proteins. Peculiarities of the PIM-derived polar profile of the group of preeclampsia-related proteins were then compared with profiles of a group of lipoproteins, antimicrobial peptides, angiogenesis-related proteins, and the intrinsically disordered proteins. Our results showed a high graphical correlation between preeclampsia proteins, lipoproteins, and the angiogenesis proteins. We also showed that many preeclampsia-related proteins contain numerous functional disordered regions. Therefore, these bioinformatics results led us to assume that the preeclampsia proteins are highly associated with the lipoproteins group, and that some preeclampsia-related proteins contain significant amounts of functional disorders.

    Previous published results have revealed that Rhinolight(®) intranasal phototherapy is safe and effective in intermittent allergic rhinitis. The present objective was to assess whether phototherapy is also safe and effective in persistent allergic rhinitis. Thirty-four patients with persistent allergic rhinitis were randomized into two groups; twenty-five subjects completed the study. The Rhinolight(®) group was treated with a combination of UV-B, UV-A, and high-intensity visible light, while the placebo group received low-intensity visible white light intranasal phototherapy on a total of 13 occasions in 6 weeks. The assessment was based on the diary of symptoms, nasal inspiratory peak flow, quantitative smell threshold, mucociliary transport function, and ICAM-1 expression of the epithelial cells. All nasal symptom scores and nasal inspiratory peak flow measurements improved significantly in the Rhinolight(®) group relative to the placebo group and this finding persisted after 4 weeks of follow-up. The smell and mucociliary functions did not change significantly in either group. The number of ICAM-1 positive cells decreased non-significantly in the Rhinolight(®) group. No severe side-effects were reported during the treatment period. These results suggest that Rhinolight(®) treatment is safe and effective in persistent allergic rhinitis.

    ABSTRACT Objectives This study investigated the association between craniofacial morphology and temporomandibular disorders in adults. The influence of different craniofacial morphologies on painful temporomandibular disorders was also evaluated. Material and Methods A total of 200 subjects were selected, including 100 with temporomandibular disorders (TMD) and 100 without TMD (control), diagnosed by research diagnostic criteria for temporomandibular disorders. All subjects were submitted to lateral cephalometric radiographs, and classified as brachyfacial, mesofacial, or dolichofacial by Ricketts’ analysis. Data were analysed by Tukey-Kramer and Chi-square tests. Results No association between craniofacial morphology and TMD was found (P = 0.6622). However, brachyfacial morphology influences the presence of painful TMD (P = 0.0077). Conclusions Craniofacial morphology is not related to temporomandibular disorders in general. PMID:27489610

    Bipolar disorders are a group of psychiatric disorders with profound negative impact on affected patients. Even if their symptomatology has long been recognized, diagnostic criteria have changed over time and diagnosis often remains difficult. The Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), issued in May 2013, comprises several changes regarding the diagnosis of bipolar disorders compared to the previous edition. Diagnostic categories and criteria for bipolar disorders show some concordance with the internationally also widely used Tenth Edition of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). However, there are also major differences that are worth highlighting. The aim of the following text is to depict and discuss those.

    A large number of materials used in the diagnosis, treatment and prevention of dental, periodontal and oral mucosal diseases may induce acute or chronic reactions in the oral cavity including allergic reactions. Clinically, it may be difficult to discriminate oral mucosal changes caused by dental materials from changes related to oral mucosal diseases. Diagnosis and management of allergic reactions in the oral mucosa may therefore be a major challenge. The purpose of this paper is to draw attention to commonly used dental materials, which can trigger typical, but also atypical, symptoms and clinical signs of an allergic reaction.

    2003-06-01

    To review concepts of neuroendocrinoimmunology and provide an overview of the role of immune dysregulation, stress, and the understanding of the pathogenesis and treatment of allergic and autoimmune diseases. Articles include original research papers, review articles, and references identified from the bibliographies of pertinent articles. Neuroendocrine hormones triggered during stress may lead to immune dysregulation or altered or amplified cytokine production, resulting in atopic, autoimmune diseases or decreased host defense. Various types of transmitter substances of the neuroendocrine-immune (NEI) network include epinephrine, norepinephrine, acetylcholine, substance P, vasoactive intestinal peptide, glucagon, insulin, cytokines, growth factors, and numerous other mediators. The stress response and induction of a dysregulation of cytokine balance can trigger the hypothalamic-pituitary-adrenal axis and sympathetic nervous system. Disorders in which abnormalities in immune function are mediated by the NEI network include allergic diseases: allergic rhinitis, atopic dermatitis, and gastro-intestinal allergies and asthma through overproduction of neuropeptides and cytokines. The multiple roles of Th2 cells in maintaining allergic inflammation and altering the balance between Th1 and Th2 responses are important mechanisms for allergic inflammation and tissue damage. In addition, several autoimmune diseases mediated by NEI network such as rheumatoid arthritis, systemic lupus erythematosus, and diabetes mellitus can be attributable to immune dysregulation. Understanding the NEI network will contribute to novel treatments for immediate and late allergic reactions. Chronic stress or depression could lead to decreased host defenses, decreased response to vaccines, viral susceptibility, or malignancy. Treatment of allergic, autoimmune diseases and asthma should include stress management and behavioral intervention to prevent stress-related immune imbalances.

    Allergic disease is caused by exposure to normally innocuous substances that activate mast cells. Mast cell-mediated allergic inflammation is closely related to a number of allergic disorders, such as anaphylaxis, allergic rhinitis, asthma and atopic dermatitis. The discovery of drugs for treating allergic disease is an interesting subject and important to human health. The aim of the present study was to investigate the anti‑allergic and anti-inflammatory effects of the aqueous extract of Pogostemon cablin (Blanco) Benth (AEPC) (a member of the Labiatae family) using mast cells, and also to determine its possible mechanisms of action. An intraperitoneal injection of compound 48/80 or a serial injection of immunoglobulin E and antigen was used to induce anaphylaxis in mice. We found that AEPC inhibited compound 48/80‑induced systemic and immunoglobulin E-mediated cutaneous anaphylaxis in a dose-dependent manner. The release of histamine from mast cells was reduced by AEPC, and this suppressive effect was associated with the regulation of calcium influx. In addition, AEPC attenuated the phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated expression of pro-inflammatory cytokines in mast cells. The inhibitory effects of AEPC on pro-inflammatory cytokines were dependent on the activation of nuclear factor (NF)-κB and p38 mitogen-activated protein kinase (MAPK). AEPC blocked the PMACI-induced translocation of NF-κB into the nucleus by hindering the degradation of IκBα and the phosphorylation of p38 MAPK. Our results thus indicate that AEPC inhibits mast cell‑mediated allergic inflammation by suppressing mast cell degranulation and the expression of pro-inflammatory cytokines caused by reduced intracellular calcium levels and the activation of NF-κB and p38 MAPK.

    Pollen is the most common aeroallergen to cause seasonal conjunctivitis. The result of allergen exposure is a strong Th2-mediated response along with conjunctival mast cell degranulation and eosinophilic infiltration. Oleanolic acid (OA) is natural a triterpene that displays strong anti-inflammatory and immunomodulatory properties being an active anti-allergic molecule on hypersensitivity reaction models. However, its effect on inflammatory ocular disorders including conjunctivitis, has not yet been addressed. Hence, using a Ragweed pollen (RWP)-specific allergic conjunctivitis (EAC) mouse model we study here whether OA could modify responses associated to allergic processes. We found that OA treatment restricted mast cell degranulation and infiltration of eosinophils in conjunctival tissue and decreased allergen-specific Igs levels in EAC mice. Th2-type cytokines, secreted phospholipase A2 type-IIA (sPLA2-IIA), and chemokines levels were also significantly diminished in the conjunctiva and serum of OA-treated EAC mice. Moreover, OA treatment also suppressed RWP-specific T-cell proliferation. In vitro studies, on relevant cells of the allergic process, revealed that OA reduced the proliferative and migratory response, as well as the synthesis of proinflammatory mediators on EoL-1 eosinophils and RBL-2H3 mast cells exposed to allergic and/or crucial inflammatory stimuli such as RWP, sPLA2-IIA or eotaxin. Taken together, these findings demonstrate the beneficial activity of OA in ocular allergic processes and may provide a new intervention strategy and potential therapy for allergic diseases.

    Allergic asthma is the most frequent disease among the chronic respiratory disorders in pediatric age with an important social impact. In the last years, many efforts have been made to identify effective preventive approaches to get a better control of symptoms and to obtain the best future outcomes for the patients. In patients with allergic asthma triggered by the exposure to indoor allergens, the avoidance is the first intervention to prevent the appearance or the worsening of bronchial symptoms. This review article summarized the most recent evidence from literature about the efficacy of specific control interventions for the most important allergens. Even if a wide spectrum of interventions has been suggested and may help to reduce exposure to trigger allergy for sensitized patients suffering from respiratory allergy, evidence supporting the efficacy of these approaches is still weak and subject of controversy. However, the exposure control to specific airborne allergens is still widely recommended and may be effective as part of a holistic approach to reduce the severity of allergic respiratory symptoms in sensitized individuals.

    Research has documented consistent and robust relations between emotional disorders (i.e., depressive and anxiety disorders) and smoking. Yet, it is presently unclear whether anxiety sensitivity--the fear of aversive internal anxiety states--accounts for the relations between emotional disorders and various smoking processes, including nicotine dependence, perceived barriers to smoking cessation, and severity of problematic symptoms during past cessation attempts. Participants (N = 465) were treatment-seeking daily tobacco smokers recruited as part of a larger tobacco-cessation study. Baseline (pretreatment) data were utilized. Emotional disorders were assessed via clinical diagnostic interview; self-report measures were used to assess anxiety sensitivity and 3 criterion variables: nicotine dependence, barriers to smoking cessation, and severity of problematic symptoms while quitting in past attempts. Emotional disorders were predictive of higher levels of nicotine dependence, greater perceived barriers to cessation, and greater severity of problematic symptoms while attempting to quit in the past; each of these relations were accounted for by the indirect effect of anxiety sensitivity. The present findings suggest that anxiety sensitivity may be an important transdiagnostic construct in explicating the nature of the relations between emotional disorders and various smoking processes.

    Objective The role of preschool onset (PO) psychiatric disorders as correlates and/or risk factors for relational aggression during kindergarten or 1st grade was tested in a sample of N = 146 preschool-age children (3 to 5.11). Method Axis-I diagnoses and symptom scores were derived using the Preschool Age Psychiatric Assessment. Children’s roles in relational aggression as aggressor, victim, aggressive-victim, or non-aggressor/non-victim were determined at preschool and again 24 months later at elementary school entry. Results Preschoolers diagnosed with PO-psychiatric disorders were 3 times as likely as the healthy preschoolers to be classified aggressors, victims, or aggressive-victims. Children diagnosed with PO-disruptive, depressive, and/or anxiety disorders were at least 6 times as likely as children without PO-psychiatric disorders to become aggressive-victims during elementary school after covarying for other key risk factors. Conclusions Findings suggested that PO-psychiatric disorders differentiated preschool and school-age children’s roles in relational aggression based on teacher-report. Recommendations for future research and preventative intervention aimed at minimizing the development of relational aggression in early childhood by identifying and targeting PO-psychiatric disorders are made.

    Aqueous solutions of myelin basic proteins do not cause allergic encephalomyelitis (EAE). They were rendered encephalitogenic for rats by admixture with kaolin, talc, glass, uncharged and cation exchange polystyrene resins, carbon and microspheres. Binding of basic protein to some of these aqueous particulate adjuvants was demonstrated spectrophotometrically. Absorption into the lymphatic system was demonstrated histologically. Binding of basic protein to adjuvant can occur in vivo. Basic protein was also bound by a carbon of relatively large particle size. Nevertheless, this carbon and certain other particulates failed to act as adjuvants, probably because they were not absorbed into the lymphatic system. An anion exchange resin, carbonyl iron, and some other particulates were abundantly absorbed into the lymphatic system but exhibited no adjuvant effect with basic protein, even though they do have an adjuvant effect for whole neural tissue. Their lack of effect with the purified antigen was explained by failure to bind basic protein. PMID:5084103

    Research into the causes of psychopathology has largely focused on two broad etiologic factors: genetic vulnerability and environmental stressors. An important role for familial/heritable factors in the etiology of a broad range of psychiatric disorders was established well before the modern era of genomic research. This review focuses on the genetic basis of three disorder categories—posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and the anxiety disorders—for which environmental stressors and stress responses are understood to be central to pathogenesis. Each of these disorders aggregates in families and is moderately heritable. More recently, molecular genetic approaches, including genome-wide studies of genetic variation, have been applied to identify specific risk variants. In this review, I summarize evidence for genetic contributions to PTSD, MDD, and the anxiety disorders including genetic epidemiology, the role of common genetic variation, the role of rare and structural variation, and the role of gene–environment interaction. Available data suggest that stress-related disorders are highly complex and polygenic and, despite substantial progress in other areas of psychiatric genetics, few risk loci have been identified for these disorders. Progress in this area will likely require analysis of much larger sample sizes than have been reported to date. The phenotypic complexity and genetic overlap among these disorders present further challenges. The review concludes with a discussion of prospects for clinical translation of genetic findings and future directions for research. PMID:26321314

    Chronic infection with hepatitis C virus (HCV) is associated with a wide spectrum of extrahepatic manifestations, affecting different organ systems. Neurological complications occur in a large number of patients and range from peripheral neuropathy to cognitive impairment. Pathogenetic mechanisms responsible for nervous system dysfunction are mainly related to the upregulation of the host immune response with production of autoantibodies, immune complexes, and cryoglobulins. Alternative mechanisms include possible extrahepatic replication of HCV in neural tissues and the effects of circulating inflammatory cytokines and chemokines. PMID:22899946

    The aim of this study is to investigate the association of allergic rhinitis in female university students with socio-economic factors and sex-hormone markers, including age at menarche, menstrual disorders, and selected anthropometrics indexes. The research was conducted among 640 female university students, aged 19-25 years. The measurements of body height, body mass, waist and hip circumference were taken. Each person completed a questionnaire. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and its allergens were defined on the basis of medical workup. We found that a significantly larger number of cases of allergic rhinitis were recorded in the university students coming from families of high socio-economic level than those from lower level. Allergic rhinitis also was more frequent in the students who spent their childhood in cities than in those who lived in the countryside. The prevalence of allergic rhinitis was inversely correlated to the number of siblings. There were no differences in the prevalence of allergic rhinitis in relation to the birth order. The estrogen level seemed unassociated with rhinitis. However, there were slightly more allergic among females with an earlier age of menarche.

    Our understanding of altered emotional processing in social anxiety disorder (SAD) is hampered by a heterogeneity of findings, which is probably due to the vastly different methods and materials used so far. This is why the present functional magnetic resonance imaging (fMRI) study investigated immediate disorder-related threat processing in 30 SAD patients and 30 healthy controls (HC) with a novel, standardized set of highly ecologically valid, disorder-related complex visual scenes. SAD patients rated disorder-related as compared with neutral scenes as more unpleasant, arousing and anxiety-inducing than HC. On the neural level, disorder-related as compared with neutral scenes evoked differential responses in SAD patients in a widespread emotion processing network including (para-)limbic structures (e.g. amygdala, insula, thalamus, globus pallidus) and cortical regions (e.g. dorsomedial prefrontal cortex (dmPFC), posterior cingulate cortex (PCC), and precuneus). Functional connectivity analysis yielded an altered interplay between PCC/precuneus and paralimbic (insula) as well as cortical regions (dmPFC, precuneus) in SAD patients, which emphasizes a central role for PCC/precuneus in disorder-related scene processing. Hyperconnectivity of globus pallidus with amygdala, anterior cingulate cortex (ACC) and medial prefrontal cortex (mPFC) additionally underlines the relevance of this region in socially anxious threat processing. Our findings stress the importance of specific disorder-related stimuli for the investigation of altered emotion processing in SAD. Disorder-related threat processing in SAD reveals anomalies at multiple stages of emotion processing which may be linked to increased anxiety and to dysfunctionally elevated levels of self-referential processing reported in previous studies. © 2016 Wiley Periodicals, Inc.

    Background Studies on the associations between smoking and allergic diseases have mostly focused on asthma. Epidemiological studies in adults on the effects of smoking on allergic diseases other than asthma, such as eczema and rhinoconjunctivitis, have been limited, and the information that is available has been inconsistent. The aim of this study was to investigate the association between smoking status and environmental tobacco smoke (ETS) exposure and the prevalence of allergic diseases. Methods Study subjects were 1743 pregnant Japanese women. The definitions of wheeze and asthma were based on criteria from the European Community Respiratory Health Survey whereas those of eczema and rhinoconjunctivitis were based on criteria from the International Study of Asthma and Allergies in Childhood. Adjustment was made for age; region of residence; family history of asthma, atopic eczema, and allergic rhinitis; household income; and education. Results Compared with never smoking, current smoking and ≥ 4 pack-years of smoking were independently positively associated with the prevalence of wheeze. There were no associations between smoking status and the prevalence of asthma, eczema, or rhinoconjunctivitis. When subjects who had never smoked were classified into four categories based on the source of ETS exposure (never, only at home, only at work, and both), exposure occurring both at home and at work was independently associated with an increased prevalence of two outcomes: wheeze and rhinoconjunctivitis. No relationships were observed between exposure to ETS and the prevalence of asthma or eczema. Conclusions Our results provide evidence that current smoking and ETS exposure may increase the likelihood of wheeze. The possibility of a positive association between ETS exposure and rhinoconjunctivitis was also suggested. PMID:22413964

    OBJECTIVES: To determine the prevalence and risk factors for work related musculoskeletal disorders among union carpenters. METHODS: A detailed questionnaire on musculoskeletal symptoms and work history was administered to 522 carpenters. The symptom questions assessed if carpenters experienced pain, numbness, or tingling in a particular body region. A subset of this group then received a physical examination of the upper extremities and knees. RESULTS: The study group was primarily white (94.9%) and male (97.8%) with a mean age of 42.3 years. The highest prevalence of work related musculoskeletal disorders cases by carpentry specialty ranged from 20%-24% for those doing drywall or ceiling, finishing or framing, and the building of concrete forms. Generally, as duration of employment increased, the prevalence of symptoms increased. An adjusted logistic regression analysis showed that the group with the longest (> or = 20 years) duration of employment in carpentry was significantly associated with work related musculoskeletal disorders of the shoulders (odds ratio (OR) 3.2, 95% confidence interval (95% CI) 1.1 to 8.9), hands or wrists (OR 3.1, 95% CI 1.1 to 8.4), and knees (OR 3.5, 95% CI 1.3 to 9.2). Also, analyses showed that carpenters who reported that they had little or no influence over their work schedule had significant increases of work related musculoskeletal disorders of the shoulders, hips, and knees with ORs of 1.9 (95% CI 1.1 to 3.2), 2.9 (95% CI 1.1 to 7.2), and 2.3 (95% CI 1.2 to 4.1), respectively. Feeling exhausted at the end of day was also a significant risk factor for work related musculoskeletal disorders of the knee (OR 1.8, 95% CI 1.1 to 3.1). Upper extremity disorders were the most prevalent work related musculoskeletal disorders reported among all carpenters. Drywall or ceiling activities involve a considerable amount of repetitive motion and awkward postures often with arms raised holding heavy dry walls in place, whereas form work is

    There is current controversy about the diagnostic overlap between personality disorders and trauma-related disorders. Applying a multicenter study design, trauma-related disorders were investigated via interview assessment in 136 patients with borderline personality disorder (BPD) in 5 specialized treatment centers. Additionally a spectrum of psychological symptoms and prevalence of lifetime traumatic experiences were assessed by questionnaire measures. Diagnostic overlap between BPD and PTSD was found to be high (79%) as well as the overlap of BPD with complex PTSD (55%) and severe dissociative disorders (41%). Including neglect and emotional violence as trauma categories, an extremely high prevalence of lifetime traumatic experiences was reported (96%). Experiences of sexual violence were reported by 48% of all female and 28% of all male patients. Severe forms of physical violence were reported by 65% of all patients. BPD patients with severe psychopathology show a high comorbidity with trauma-related disorders including dissociative disorders. This association has to be taken into account when planning psychological treatment.

    To discuss current evidence of global climate change and its implications for allergic rhinitis and other allergic respiratory diseases. Global climate change is evidenced by increasing average earth temperature, increasing anthropogenic greenhouse gas levels, and elevated pollen levels. Pollutants of interest include carbon dioxide (CO2), ozone (O3), and nitrous oxide (NO2) because they can enhance the allergic response and lead to increased symptoms of allergic respiratory diseases. Heightened CO2 levels stimulate pollen production via photosynthesis and increased growth in multiple plant species investigated. Although worsened air quality appears to increase prevalence of allergic rhinitis, the effects of increased temperature are less certain. The findings of increased aeroallergen levels likely contribute to increases in presentation of allergic diseases, although more healthcare impact studies are necessary. Although recent literature indicates and strongly supports changes in temperature, pollution levels, and aeroallergen levels, more longitudinal epidemiologic surveillance of allergic diseases in relation to climate change as well as pathophysiologic studies on changing aeroallergen effects on allergic diseases are needed.

    Picroside II isolated from Pseudolysimachion rotundum var. subintegrum has been used as traditional medicine to treat inflammatory diseases. In this study, we assessed whether picroside II has inhibitory effects on airway inflammation in a mouse model of house dust mite (HDM)-induced asthma. In the HDM-induced asthmatic model, picroside II significantly reduced inflammatory cell counts in the bronchoalveolar lavage fluid (BALF), the levels of total immunoglobulin (Ig) E and HDM-specific IgE and IgG1 in serum, airway inflammation, and mucus hypersecretion in the lung tissues. ELISA analysis showed that picroside II down-regulated the levels of Th2-related cytokines (including IL-4, IL-5, and IL-13) and asthma-related mediators, but it up-regulated Th1-related cytokine, IFNγ in BALF. Picroside II also inhibited the expression of Th2 type cytokine genes and the transcription factor GATA3 in the lung tissues of HDM-induced mice. Finally, we demonstrated that picroside II significantly decreased the expression of GATA3 and Th2 cytokines in developing Th2 cells, consistent with in vivo results. Taken together, these results indicate that picroside II has protective effects on allergic asthma by reducing GATA3 expression and Th2 cytokine bias. PMID:27870920

    BACKGROUND AND OBJECTIVES: The relationship between allergic diseases and internalizing disorders has not been well characterized with regard to multiple allergic diseases or longitudinal study. The objective of this study was to examine the association between multiple allergic diseases in early childhood with validated measures of internalizing disorders in the school-age years. METHODS: Children enrolled in the Cincinnati Childhood Allergy and Air Pollution Study underwent skin testing and examinations at ages 1, 2, 3, 4, and 7 years. At age 7, parents completed the Behavior Assessment System for Children, Second Edition (BASC-2), a validated measure of childhood behavior and emotion. The association between allergic diseases at age 4, including allergic rhinitis, allergic persistent wheezing, atopic dermatitis, and allergic sensitization, and BASC-2 internalizing, anxiety, and depression T scores at age 7 was examined by logistic and linear regression, adjusting for covariates. RESULTS: The cohort included 546 children with complete information on allergic disease and BASC-2 outcomes. Allergic rhinitis at age 4 was significantly associated with elevated internalizing (adjusted odds ratio [aOR]: 3.2; 95% confidence interval [CI]: 1.8–5.8), anxiety (aOR: 2.0; 95% CI: 1.2–3.6), and depressive scores (aOR: 3.2; 95% CI: 1.7–6.5) at age 7. Allergic persistent wheezing was significantly associated with elevated internalizing scores (aOR: 2.7; 95% CI: 1.2–6.3). The presence of >1 allergic disease (aOR: 3.6; 95% CI: 1.7–7.6) and allergic rhinitis with comorbid allergic disease(s) (aOR: 4.3; 95% CI: 2.0–9.2) at age 4 had dose-dependent associations with internalizing scores. CONCLUSIONS: Children with allergic rhinitis and allergic persistent wheezing at age 4 are at increased risk of internalizing behaviors at age 7. Furthermore, multiple allergic diseases had a dose-dependent association with elevated internalizing scores. PMID:26715608

    FOXG1-related disorders are caused by heterozygous mutations in FOXG1 and result in a spectrum of neurodevelopmental phenotypes including postnatal microcephaly, intellectual disability with absent speech, epilepsy, chorea, and corpus callosum abnormalities. The recurrence risk for de novo mutations in FOXG1-related disorders is assumed to be low. Here, we describe three unrelated sets of full siblings with mutations in FOXG1 (c.515_577del63, c.460dupG, and c.572T>G), representing familial recurrence of the disorder. In one family, we have documented maternal somatic mosaicism for the FOXG1 mutation, and all of the families presumably represent parental gonadal (or germline) mosaicism. To our knowledge, mosaicism has not been previously reported in FOXG1-related disorders. Therefore, this report provides evidence that germline mosaicism for FOXG1 mutations is a likely explanation for familial recurrence and should be considered during recurrence risk counseling for families of children with FOXG1-related disorders.

    Previous research indicates that attention-deficit/hyperactivity disorder (ADHD) is highly associated with substance use disorders (SUD). However, these studies have failed to clarify the nature of the overlap. The main aim of this study was to explore whether the overlap between ADHD and SUD could be explained by shared genetic and environmental factors or by harmful effects of ADHD medication. We employed a matched cohort design across different levels of family relatedness recorded from 1973-2009. By linking longitudinal Swedish national registers, 62,015 ADHD probands and first-degree and second-degree relatives were identified and matched 1:10 with control subjects without ADHD and their corresponding relatives. Any record of SUD was defined by discharge diagnoses of the International Classification of Diseases or a purchase of any drug used in the treatment of SUD. First-degree relatives of ADHD probands were at elevated risk for SUD (odds ratios 2.2 and 1.8) compared with relatives of control subjects. The corresponding relative risk in second-degree relatives was substantially lower (odd ratios 1.4 and 1.4). The familial aggregation patterns remained similar for first-degree and second-degree relatives after excluding individuals with coexisting disorders such as schizophrenia, bipolar disorder, depression, and conduct disorder. Our findings suggest that the co-occurrence of ADHD and SUD is due to genetic factors shared between the two disorders, rather than to a general propensity for psychiatric disorders or harmful effects of ADHD medication.

    Integration of protein structural information with human genetic variation and pathogenic mutations is essential to understand molecular mechanisms associated with the effects of polymorphisms on protein interactions and cellular processes. We investigate occurrences of non-synonymous SNPs in ordered and disordered protein regions by systematic mapping of common variants and disease-related SNPs onto these regions. We show that common variants accumulate in disordered regions; conversely pathogenic variants are significantly depleted in disordered regions. These different occurrences of pathogenic and common SNPs can be attributed to a negative selection on random mutations in structurally highly constrained regions. New approaches in the study of quantitative effects of pathogenic-related mutations should effectively account for all the possible contexts and relative functional constraints in which the sequence variation occurs.

    Posttraumatic stress disorder (PTSD) is a common, frequently chronic, and disabling condition which, along with acute stress disorder (ASD), is categorized as a trauma- and stressor-related disorder by the DSM-5. These disorders are unique in requiring exposure to a severe stressor, which implies that potential sufferers could be identified and helped before developing a disorder. Research on prevention strategies for stress-related disorders has taken a number of avenues, including intervention before and after trauma and the use of both psychosocial and somatic approaches. Despite advances in neurobiological understanding of response to trauma, clinical evidence for preventive interventions remains sparse. This review provides an overview of prevention approaches and summarizes the existing literature on prevention of ASD and PTSD, including clinical and preclinical studies. Given the potential benefits to trauma survivors and society, the development of effective preventive interventions should be given greater priority. Resources should be directed to adequately test promising interventions in clinical trials, and research should be conducted according to translational research principles in which preclinical research informs the design of clinical studies.

    2014-01-01

    Stress is associated with the onset and severity of several psychiatric disorders that occur more frequently in women than men, including posttraumatic stress disorder (PTSD) and depression. Patients with these disorders present with dysregulation of several stress response systems, including the neuroendocrine response to stress, corticolimbic responses to negatively valenced stimuli, and hyperarousal. Thus, sex differences within their underlying circuitry may explain sex biases in disease prevalence. This review describes clinical studies that identify sex differences within the activity of these circuits, as well as preclinical studies that demonstrate cellular and molecular sex differences in stress responses systems. These studies reveal sex differences from the molecular to the systems level that increase endocrine, emotional, and arousal responses to stress in females. Exploring these sex differences is critical because this research can reveal the neurobiological underpinnings of vulnerability to stress-related psychiatric disorders and guide the development of novel pharmacotherapies.

    The sleep disorder in pregnant women remains unfamiliar to perinatal care providers, resulting in lack of appropriate care. This study was designed to investigate the prevalence of sleep disorder-related symptoms in pregnant women and to identify the associated risk factors. Married pregnant women were enrolled from their first trimester and followed up until delivery. Nonpregnant married healthy women were selected as controls. A survey questionnaire was administered to each of them. We successfully performed a survey to 1,993 pregnant women and 598 nonpregnant women. The overall prevalence of sleep disorder-related symptoms in pregnant women was significantly higher than the controls (56.1 vs. 29.9 %, P < 0.05). There was higher prevalence of snoring (30.2 %), observed sleep apnea (1.1 %), mouth breathing (23.7 %), nocturnal arousal (46.5 %), insomnia (35.1 %), and daytime sleepiness (52.6 %) in pregnant women. There were no significant differences of the prevalence of bruxism (7.0 vs. 6.7 %), sleep talking (8.1 vs. 7.2 %), and sleep walking (0.4 vs. 0.2 %) between the two groups (P > 0.05). Nocturnal sleep time (8.0 ± 1.3 h) was less in the third trimester compared with the nonpregnant women (8.2 ± 1.1 h) (P < 0.05). Smoking (OR = 3.39), drinking (OR = 2.40), allergic rhinitis/asthma (OR = 1.71), an obvious difference in neck circumference (OR = 1.11), and waistline (OR = 1.07) changes between the first and third trimesters were the risk factors for sleep disorder-related problems. There is a high prevalence of sleep disorder-related symptoms in pregnant women. Our data may provide a baseline for prevention and treatment of sleep disturbances in pregnant women.

    Panic disorder (PD) patients show aberrant neural responses to threatening stimuli in an extended fear network, but results are only partially comparable, and studies implementing disorder-related visual scenes are lacking as stimuli. The neural responses and functional connectivity to a newly developed set of disorder-related, ecologically valid scenes as compared with matched neutral visual scenes, using event-related functional magnetic resonance imaging (fMRI) in 26 PD patients and 26 healthy controls (HC) were investigated. PD patients versus HC showed hyperactivation in an extended fear network comprising brainstem, insula, thalamus, anterior, and mid-cingulate cortex and (dorso-)medial prefrontal cortex for disorder-related versus neutral scenes. Amygdala differences between groups failed significance. Subjective levels of anxiety significantly correlated with brainstem activation in PD patients. Analysis of functional connectivity by means of beta series correlation revealed no emotion-specific alterations in connectivity in PD patients versus HC. The results suggest that subjective anxiety evoked by external stimuli is directly related to altered activation in the homeostatic alarm system in PD. With novel disorder-related stimuli, the study sheds new light on the neural underpinnings of pathological threat processing in PD.

    Immediate allergic response has long been recognized to be related to the activation of mast cells by antigen. The role of the mast cells as producers of cytokines, however, has only more recently been extensively studied. The effect of TH2 lymphocytes in the inflammatory process is now well recognized in animal models. The central role of cytokines in the allergic inflammatory response is currently an area of intense clinical investigation. Cytokines influence production, migration, and activation of basophils. A wide array of cytokines is produced by mast cells upon initiation of the immediate allergic response. These cytokines influence a number of other different cells including basophils and eosinophils, and also activate lymphocytes, thus perpetuating allergic inflammation.

    In the last decade, the ingestion of gluten, a heterogeneous complex of proteins present in wheat, rice, barley and probably in oats, has been associated with clinical disorders, such as celiac disease, wheat allergy and recently to non-celiac gluten sensitivity or wheat intolerance syndrome. Gluten-related disorders, which are becoming epidemiologically relevant with an estimated global prevalence of about 5%, require the exclusion of gluten from the diet. For the past 5 years, an important shift in the availability of gluten-free products, together with increased consumption in the general population, has been recorded and is estimated to be about 12-25%. Many people follow a self-prescribed gluten-free diet, despite the fact that the majority have not first been previously excluded, or confirmed, as having gluten disorders. They rely on claims that a gluten-free diet improves general health. In this review, we provide an overview of the clinical disorders related to gluten or wheat ingestion, pointing out the current certainties, open questions, possible answers and several doubts in the management of these conditions. KEY MESSAGE Incidence of gluten-related disorders is increased in the last decade and self-diagnosis is frequent with inappropriate starting of a gluten-free diet. Gluten and wheat are considered as the most important triggers to coeliac disease, wheat allergy and non-celiac gluten sensitivity. Pediatricians, allergologist and gastroenterologist are involved in the management of these conditions and appropriate diagnostic protocols are required.

  9. Rhinoviruses, Allergic Inflammation, and Asthma

    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.

    Diagnosis early in life, sensitization, asthma endotypes, monitoring of disease and treatment progression are key motivations for the exploration of biomarkers for allergic rhinitis and allergic asthma. The number of genes related to allergic rhinitis and allergic asthma increases steadily; however, prognostic genes have not yet entered clinical application. We hypothesize that the combination of multiple genes may generate biomarkers with prognostic potential. The current review attempts to group more than 161 different potential biomarkers involved in respiratory inflammation to pave the way for future classifiers. The potential biomarkers are categorized into either epithelial or infiltrate-derived or mixed origin, epithelial biomarkers. Furthermore, surface markers were grouped into cell-type-specific categories. The current literature provides multiple biomarkers for potential asthma endotypes that are related to T-cell phenotypes such as Th1, Th2, Th9, Th17, Th22 and Tregs and their lead cytokines. Eosinophilic and neutrophilic asthma endotypes are also classified by epithelium-derived CCL-26 and osteopontin, respectively. There are currently about 20 epithelium-derived biomarkers exclusively derived from epithelium, which are likely to innovate biomarker panels as they are easy to sample. This article systematically reviews and categorizes genes and collects current evidence that may promote these biomarkers to become part of allergic rhinitis or allergic asthma classifiers with high prognostic value.

    Gluten-related disorders such as coeliac disease, wheat allergy and noncoeliac gluten sensitivity are increasingly being diagnosed in children. Coeliac disease occurs frequently, affecting 1-3% of the Western population. The condition manifests at a very young age, more so in girls, and is related to the HLA genotype. Coeliac disease might be considered a public health problem and, as primary prevention is not possible, the debate on mass screening should be reopened. Wheat proteins, including gluten, are responsible for one of the most common food allergies in children: wheat allergy. Unlike coeliac disease and wheat allergy, noncoeliac gluten sensitivity is an unclear and controversial entity. These three gluten-related disorders are treated with a gluten-free diet. In coeliac disease, the diet should be strictly followed, whereas wheat allergy only requires wheat elimination and in noncoeliac gluten sensitivity occasional trials of gluten reintroduction can be done. A good diagnostic work-up is important for gluten-related disorders in childhood to avoid unnecessary restrictive diets in children. In this Review, we provide an overview of the pathogenesis, diagnosis and management of the most common gluten-related disorders in children.

    Allergies are generally thought to be a detrimental outcome of a mistargeted immune response that evolved to provide immunity to macro-parasites. Here we present arguments to suggest that allergic immunity plays an important role in host defense against noxious environmental substances, including venoms, hematophagous fluids, environmental xenobiotics and irritants. We argue that appropriately targeted allergic reactions are beneficial, although they can become detrimental when excessive. Furthermore, we suggest that allergic hypersensitivity evolved to elicit anticipatory responses and to promote avoidance of suboptimal environments. PMID:22538607

    We have studied asthma and allergic rhinitis prevalence in Swedish conscripts born 1973-1977 according to the military service conscription register in relation to the socio-economic status and country of birth of the conscripts and their parents, and age when granted residency in Sweden. There was an increase in prevalence of asthma and allergic rhinitis over time in all groups irrespective of country of birth or ethnic origin. Conscripts who themselves were born in Africa, Asia, Latin America and the Mediterranean had a significantly lower risk for asthma and allergic rhinitis than Swedish-born conscripts. The risk of atopic disorder among the foreign-born conscripts increased with time of residency in Sweden. Conscripts with mothers from Latin America, Asia and Africa were identified as having the highest risk for atopic disorder among Swedish-born conscripts with high socio-economic status; the adjusted risk ratio (RR) for asthma was 2.6 (95% CI 1.7-4.0) and that for allergic rhinitis was 2.0 (1.5-2.6). The conscripts with mothers from the Mediterranean had the lowest risk for atopic disorders of the Swedish-born conscripts with low socio-economic status; the RR for asthma was 0.43 (0.34-0.56) and that for allergic rhinitis was 0.84 (0.76-0.93). This study demonstrates that factors related to migration and ethnicity are important determinants of atopic disorder among Swedish conscripts.

    2014-08-01

    The food-borne parasite Anisakis is an important hidden food allergen. Anisakis is a parasitic nematode which has a third-stage larval form that infects mainly fish, and ingestion of contaminated seafood can result in severe allergic reactions. Symptoms experienced due to exposure to this parasite include gastrointestinal disorders, urticaria, dermatitis, asthma and even anaphylaxis. Accurate prevalence data of allergic sensitisation to Anisakis are difficult to estimate due to the lack of well-designed population-based studies. Current diagnostic approaches rely on the detection of serum IgE antibodies to allergenic proteins, which however demonstrate considerable immunological cross-reactivity to other invertebrate allergens. While exposure to this parasite seems to increase due to the increasing consumption of seafood worldwide, the immunology of infection and allergic sensitization is not fully understood.

    Rorschach scales were used to examine the quality of thought disturbance and object relations in boys meeting the Diagnostic and Statistical Manual of Mental Disorders, third edition (DSM-III; American Psychiatric Association, 1980) criteria for separation anxiety disorder (SAD). Nineteen urban, middle and low socioeconomic status (SES), SAD boys were compared to a group of 14 male control subjects. The hypotheses of the study were that SAD boys as compared to controls would: (a) have significantly more thought disordered responses as measured by a Rorschach Thought Disorder Scale (Blatt & Ritzler, 1974), and (b) evidence significantly less adaptive object relations scale scores as measured by the Mutuality of Autonomy Scale (Urist, 1977). Results confirmed both hypotheses. The SAD group had more thought disordered responses and more disrupted object relations scores than the controls. Ideas and images of these boys were found to generally be more unstable, boundary compromised, fluid, idiosyncratic, tangential, and psychotic-like than the controls. It was concluded that these boys possess a significant potential to have thinking abnormalities that will interfere with their independent functioning. Concerning their object relations scores, the SAD subjects were found to have significantly fewer benign, adaptive object interactional percepts, and a greater number of dependent and/or clinging interactional object representations (imagery) than the controls. This study supports the viewpoint that SAD boys are deeply psychologically troubled.

    Obsessive-compulsive disorder (OCD) is a clinical syndrome whose hallmarks are excessive, anxiety-evoking thoughts and compulsive behaviors that are generally recognized as unreasonable, but which cause significant distress and impairment. When these are the exclusive symptoms, they constitute uncomplicated OCD. OCD may also occur in the context of other neuropsychiatric disorders, most commonly other anxiety and mood disorders. The question remains as to whether these combinations of disorders should be regarded as independent, cooccurring disorders or as different manifestations of an incompletely understood constellation of OCD spectrum disorders with a common etiology. Additional considerations are given here to two potential etiology-based subgroups: (i) an environmentally based group in which OCD occurs following apparent causal events such as streptococcal infections, brain injury, or atypical neuroleptic treatment; and (ii) a genomically based group in which OCD is related to chromosomal anomalies or specific genes. Considering the status of current research, the concept of OCD and OCD-related spectrum conditions seems fluid in 2010, and in need of ongoing reappraisal.

    Parabens, which are a homologous series of esters of p-hydroxybenzoic acid, have been used as preservatives in cosmetics, medicines and foods because of their antimicrobial activity. However, parabens in cosmetics have been suspected to cause allergic contact dermatitis. In this study, we examined paraben-induced histamine release from rat peritoneal mast cells and skin reaction in guinea pigs using a series of 17 parabens with different alcohol side chains, ranging from methylparaben to dodecylparaben. Octylparaben showed the greatest histamine release-inducing activity from mast cells, and the activity was decreased in shorter- and longer-side-chain parabens. Octyl benzoate, octyl o-hydroxybenzoate and phenyloctane caused no significant degranulation of mast cells, whereas octyl m-hydroxybenzoate, octyl p-hydroxybenzoate and octyl phenol induced concentration-related degranulation. Metabolites of these parabens (p-hydroxybenzoic acid and alcohols) did not show histamine release-inducing activity. In the guinea pig skin reaction test, heptylparaben induced a typical strong skin reaction, while butylparaben induced a typical weak skin reaction, and methylparaben and dodecylparaben were inactive. Metabolites of parabens (p-hydroxybenzoic acid and alcohols) were also inactive. These results indicate that interaction of parabens with rat mast cells requires a minimum length and adequate lipophilicity of the alkyl side chain. Since metabolites of parabens were inactive, parabens appear to be direct-acting allergens.

  2. Chlorination products: emerging links with allergic diseases.

    2007-01-01

    Exposure of the human population to chlorination products has considerably increased during the 20(th) century especially after the 1960s with the development of public and leisure pools. The present article summarizes current knowledge regarding the human exposure to chlorination products and reviews studies suggesting that these chemicals might be involved in the development or exacerbation of allergic diseases. Populations regularly in contact with chlorination products such as swimmers, lifeguards or workers using chlorine as cleaning or bleaching agent show increased risks of allergic diseases or of respiratory disorders frequently associated with allergy. Experimental evidence suggests that chlorination products promote allergic sensitization by compromising the permeability or the immunoregulatory function of epithelial barriers. These findings led to the chlorine hypothesis proposing that the rise of allergic diseases could result less from the declining exposure to microbial agents (the hygiene hypothesis) than from the increasing and largely uncontrolled exposure to products of chlorination, the most widely used method to achieve hygiene in the developed world. Giving the increasing popularity of water recreational areas, there is an obvious need to assess the effects of chlorine-based oxidants on human health and their possible implication in the epidemic of allergic diseases.

    Heritable ectopic mineralization disorders represent a phenotypically diverse group of conditions characterized by deposition of calcium phosphate complexes in soft connective tissues. The prototype of such conditions is pseudoxanthoma elasticum (PXE), and related conditions with overlapping clinical features include generalized arterial calcification of infancy (GACI) and arterial calcification due to CD73 deficiency (ACDC). Molecular genetic investigations have revealed mutations in the genes physiologically involved in generation of inorganic pyrophosphate (PPi) and phosphate (Pi), and the findings suggest a unifying pathomechanism relating to reduced PPi/Pi ratio. This hypothesis is based on the notion that PPi serves as a powerful inhibitor of mineralization while Pi is a pro-mineralization factor, and an appropriate PPi/Pi ratio is critical for prevention of ectopic mineralization under homeostatic conditions. PXE International, the premiere patient support organization, advocating on behalf of patients and families with PXE, sponsors regular research meetings evaluating the progress in this and related ectopic mineralization disorders. The latest meetings were held in September 2014 in Bethesda, MD and in September 2015 in Budapest, Hungary. This report summarizes the latest progress in research on PXE and related ectopic mineralization disorders, based on presentations and discussions in these meetings, with pharmacologic implications for currently intractable disorders.

    The gastrointestinal form of food allergy is very common in children. The most frequently observed types are allergic proctitis and proctocolitis. In most cases the symptoms subside within the first 2 months of life. The babies seem healthy, and the only abnormality is a small amount of blood in stool. Symptoms can also include small intestine inflammation and colitis. Patients may present with irritability, abdominal pain, flatulence, colic, postprandial vomiting, chronic diarrhoea, and hindered physical development. The diagnosis of allergic enteritis is based on the clinical examination and the results of additional tests including an endoscopy of the lower digestive tract with histopathological assessment. Cow’s milk proteins are the most common nutrition proteins responsible for the development of the symptoms of allergic enteritis. The most essential method of treating allergic enteritis is the elimination diet. The symptoms should subside within 1–2 weeks from the beginning of the diet. PMID:28337229

    Allergic rhinitis is the most common chronic childhood disease. Reduced quality of life is frequently caused by this IgE-mediated disease, including sleep disturbance with subsequent decreased school performance. Asthma and exercise-induced bronchospasm are commonly seen concurrently with allergic rhinitis, and poorly controlled allergic rhinitis negatively affects asthma outcomes. Nonsedating antihistamines or intranasal azelastine are effective agents to manage allergic rhinitis, often in combination with oral decongestants. For moderate to severe persistent disease, intranasal corticosteroids are the most effiective agents. Some patients require concomitant intranasal corticosteroids and nonsedating antihistamines for optimal management. Other available agents include leukotriene receptor antagonists, intranasal cromolyn, intranasal ipratropium, specific immunotherapy, and anti-IgE therapy. PMID:23118635

    Impulse control disorders (ICDs) are a relatively recent addition to the behavioral spectrum of PD-related non-motor symptoms. Social and economic factors may play a role on the ICD phenotype of PD patients. The aim of this study is to determine the prevalence and characterize the clinical profile of ICDs in a sample of low-income, low-education PD patients with no social security benefits from a Latin American country. We included 300 consecutive PD patients and 150 control subjects. The presence of ICD and related disorders was assessed using a structured interview. After the interview and neurological evaluation were concluded, all subjects completed the Questionnaire for Impulsive-compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS). Regarding ICDs and related disorders (hobbyism-punding), 25.6% (n = 77) of patients in the PD group and 16.6% (n = 25) in the control group fulfilled criteria for at least one ICD or related disorder (p = 0.032). There was a statistically significant difference in the QUIP-RS mean score between PD and control subjects (5.6 ± 9.7 and 2.7 ± 4.21, p = 0.001). The most common ICD was compulsive eating for both PD (8.6%) and control (2.6%) groups. The results of this study confirm that for this population, symptoms of an ICD are significantly more frequent in PD subjects than in control subjects. Nevertheless, socioeconomic differences may contribute to a lower overall frequency and distinct pattern of ICDs in PD patients compared with what has been reported in other countries.

    The present study investigated symptom relations between two highly comorbid disorders--posttraumatic stress disorder (PTSD) and generalized anxiety disorder (GAD)--by exploring their underlying dimensions. Based on theory and prior empirical research it was expected that the dysphoria factor of PTSD would be more highly related to GAD. As part of a longitudinal project of mental health among Ohio National Guard Soldiers, 1266 subjects were administered the Posttraumatic Stress Disorder Checklist (PCL) and Generalized Anxiety Disorder-7 scale (GAD-7). Confirmatory factor analyses (CFAs) were conducted to examine two models of PTSD and to determine which PTSD factors were more related to the GAD factor. The results indicate that the GAD factor was significantly more highly correlated with PTSD's dysphoria factor than with all other PTSD factors, including PTSD's reexperiencing factor, avoidance factor, and hyperarousal factor. Results indicate GAD was not significantly more highly correlated with numbing than most other factors of PTSD. The results are consistent with prior research. Implications of the results are discussed in regards to PTSD in DSM-5, comorbidity and diagnostic specificity.

    Oxaliplatin (L-OHP), a platinum-containing antineoplastic agent, is a key drug for the treatment of colorectal cancer. However, it is often difficult to continue with its treatment because of the expression of allergic reactions. This study was an investigation of the expression of allergic reactions resulting from administration of L-OHP. A retrospective analysis was performed on patients undergoing therapeutic regimens including L-OHP, from April 2009 to November 2010 in Juntendo University Urayasu Hospital. The results showed that allergic reactions were expressed in 15 out of 81 patients (18. 5%). A high correlation was found between the time from administration until expression of the allergic reaction, and the number of treatment courses (r=-0. 521, p=0. 047). When patient characteristics were compared between the allergic reaction group and the no-reaction group, it was suggested that differences due to the regimen or the presence or absence of liver metastasis, which is considered to be related to drug metabolism, had no effect. Items showing significant differences were sexual difference(p=0. 022)and the effect of changes depending on the dose form of L-OHP(p=0. 003). It was possible to continue treatment with L-OHP in six patients even after expression of allergic reactions. Anti-allergy measures such as additional administration of steroids or antihistamines were suggested to be useful for continuing treatment.

    Snoring and obstructive sleep apnoea (OSA) are disorders within a wide spectrum of sleep-related breathing disorders (SRBD). Given the obesity epidemic, these conditions will become increasingly prevalent and continue to serve as a large economic burden. A thorough clinical evaluation and appropriate investigations will allow stratification of patients into appropriate treatment groups. A multidisciplinary team is required to manage these patients. Patient selection is critical in ensuring successful surgical and non-surgical outcomes. A wide range of options are available and further long term prospective studies, with standardised data capture and outcome goals, are required to evaluate the most appropriate techniques and long term success rates.

    Children exposed to traumatic stress are vulnerable to a variety of stress-related disorders other than classical post-traumatic stress disorder. Several case histories are presented to illustrate some of the diversity of how traumatic stress may manifest in children. African-American children are the main focus of this article as political, economic, social, and morbidity and mortality indicators suggest that African-American children are at high risk for exposure to potentially traumatic stressors. Different presentations of traumatic, stress are discussed in an effort to broaden our understanding of the outcome of traumatic stress to fully help traumatized children. PMID:9170834

    Allergic bronchopulmonary aspergillosis is a slowly progressive disease, caused by the fungus Aspergillus fumigatus hypersensitivity when it is found in the airway. It usually affects asthmatics and patients with cystic fibrosis. We report the case of a 20-year-old male patient, student, farmer and rancher with chronic respiratory disease. The diagnosis of allergic bronchopulmonary aspergillosis was made on the basis of the clinical symptoms and complementary studies.

    Purpose of review Allergic diseases are among the most prevalent chronic diseases of childhood, affecting more than 7 million children in the United States. Epidemiological evidence supports the idea that the inception of allergic diseases is typically before the pre-school years, even when chronic symptoms do not emerge until adulthood. The role of epigenetic mechanisms (particularly DNA methylation) in allergic disease is under active investigation because these mechanisms are known to be at the interface among gene regulation, environmental stimuli and developmental processes, all of which are essential for the pathogenesis for asthma and allergy. This article specifically reviews genome-wide DNA methylation studies in allergic disease. Recent findings Differential DNA methylation at specific regions appears to be associated with concurrent allergic disease. A few studies have identified methylation signatures predictive of disease. Summary DNA methylation signatures have been shown be associated with several allergic disease phenotypes, typically concurrently with disease. The few that have been found to precede diagnosis are especially interesting because they highlight an early trajectory to disease. PMID:26418323

    The allergic diseases are complex phenotypes for which a strong genetic basis has been firmly established. Genome-wide association studies (GWAS) has been widely employed in the field of allergic disease, and to date significant associations have been published for nearly 100 asthma genes/loci, in addition to multiple genes/loci for AD, AR and IgE levels, for which the overwhelming number of candidates are novel and have given a new appreciation for the role of innate as well as adaptive immune-response genes in allergic disease. A major outcome of GWAS in allergic disease has been the formation of national and international collaborations leading to consortia meta-analyses, and an appreciation for the specificity of genetic associations to sub-phenotypes of allergic disease. Molecular genetics has undergone a technological revolution, leading to next generation sequencing (NGS) strategies that are increasingly employed to hone in on the causal variants associated with allergic diseases. Unmet needs in the field include the inclusion of ethnically and racially diverse cohorts, and strategies for managing ‘big data’ that is an outcome of technological advances such as sequencing.

    Divorce is associated with a multitude of outcomes related to health and well-being. Data from a representative community sample (N = 1,241) of St. Louis residents (ages 55-64) were used to examine associations between personality pathology and divorce in late midlife. Symptoms of the 10 DSM-IV personality disorders were assessed with the Structured Interview for DSM-IV Personality and the Multisource Assessment of Personality Pathology (both self and informant versions). Multiple regression analyses showed Paranoid and Histrionic personality disorder symptoms to be consistently and positively associated with number of divorces across all three sources of personality assessment. Conversely, Avoidant personality disorder symptoms were negatively associated with number of divorces. The present paper provides new information about the relationship between divorce and personality pathology at a developmental stage that is understudied in both domains.

    Impairments in language and communication are a defining feature of autism spectrum disorders. There is significant variability in linguistic abilities in autism spectrum disorders. They have difficulties with certain aspects of language such as semantics functions, syntax, prosody and phonology, although the most evident language deficits concern to pragmatics functioning. These language difficulties can cause serious problems in social interaction. The neural bases underlying this failure to develop language are unknown. Several functional and structural imaging studies have identified irregularities in language-related regions in autism spectrum disorders, such as morphometric differences in Broca's area and Wernicke's area, and patterns of reduced or reversed laterality in frontal and temporal cortex. There is also decreased functional connectivity between anterior and posterior language regions.

  5. Somatic symptom and related disorders in Asians and Asian Americans.

    PubMed

    2014-02-01

    Somatic manifestation is common in the Asian population. The frequent occurrence of somatic symptom and related disorders among Asians could well be explained by an overt emphasis on 'somatic' idioms of distress on the one hand, and unacceptability and stigma attached to psychological expression of distress on the other. Assessment and diagnosis of somatoform disorders is complicated by the scarcity of cross-culturally validated instruments. Likewise, management is also based on Western literature in which psychological interventions override pharmacological treatment. DSM-5 has broadened the scope of somatoform disorders and emphasizes the concept rather than simply counting symptoms. These changes are expected to have a positive impact cross-culturally.

    Animal models of hemophilia and related diseases are important for development of novel treatments and to understand the pathophysiology of bleeding disorders in humans. Testing in animals with the equivalent human disorder provides informed estimates of doses and measures of efficacy, which aids in design of human trials. Many models of hemophilia A, hemophilia B, and von Willebrand disease have been developed from animals with spontaneous mutations (hemophilia A dogs, rats, sheep; hemophilia B dogs; and von Willebrand disease pigs and dogs), or by targeted gene disruption in mice to create hemophilia A, B, or VWD models. Animal models have been used to generate new insights into the pathophysiology of each bleeding disorder and also to perform pre-clinical assessments of standard protein replacement therapies as well as novel gene transfer technology. Both the differences between species and differences in underlying causative mutations must be considered in choosing the best animal for a specific scientific study PMID:23956467

  7. Anxiety disorders and control related beliefs: the exemplar of Obsessive-Compulsive Disorder (OCD).

    2006-09-01

    Beliefs about control have been postulated to be important to anxiety and mood disorders. In particular, the phenomenology of Obsessive-Compulsive Disorder (OCD) suggests that it may be an exemplar of an anxiety disorder where control issues related to the self (behavior and thoughts) and world (the external environment) are particularly important. However, only beliefs concerning the need to control thoughts have been incorporated into contemporary theories of OCD. This article summarizes the theoretical and empirical research relevant to control-related beliefs in OCD. It is suggested that discrepancies between an individual's desired level of control and their perceived level of control could contribute to OCD symptoms, and exacerbate the tendency for individuals with OCD to engage in magical ideation and superstitious rituals. Overall, this review demonstrates how consideration of control cognitions could enhance our understanding of OCD and further improve its treatment.

    This paper presents gender-related features of Delusional Disorder. It is part of the Halle Delusional Syndromes Study (HADES-Study). All inpatients fulfilling the DSM-IV/ICD-10 criteria of Delusional Disorder/Persistent Delusional Disorder (DD) during a 14-year period were included and followed up for an average of 10.8 years. Gender distribution was almost equal, women became ill significantly later than men, and almost all women had a stable diagnosis-in contrast to men. The great majority of women, at the end of the follow-up period, had an unremitted DD. Women more frequently had low social functioning at admission, but then were more compliant and received more frequently pharmacological medication. There were no differences in the delusional topic and no differences regarding long-term disability and autarky. In spite of previous reports, the HADES-Study found no gender difference in the frequency of DD. However, men tended more frequently to change into schizophrenia and schizoaffective disorder. In these cases, the DD might have been a prodrome of schizophrenia or schizoaffective disorder, which manifests later in life. Although in both female and male DD patients, the majority remained unremitted, almost none of them lost their autarky (independent living). While women more frequently received psychopharmacological medication, their DD was usually found to be unremitted.

    Despite the huge body of research on social support, literature has been primarily focused on its beneficial role for both physical and mental health. It is still unclear why people with mental and neurological disorders experience low levels of social support. The main objective of this study was to explore what are the strongest factors related to social support and how do they interact with each other in neuropsychiatric disorders. The study used cross-sectional data from 722 persons suffering from dementia, depression, epilepsy, migraine, multiple sclerosis, Parkinson's disease, schizophrenia, stroke, and substance use disorders. Multiple linear regressions showed that disability was the strongest factor for social support. Extraversion and agreeableness were significant personality variables, but when the interaction terms between personality traits and disability were included, disability remained the only significant variable. Moreover, level of disability mediated the relationship between personality (extraversion and agreeableness) and level of social support. Moderation analysis revealed that people that had mental disorders experienced lower levels of support when being highly disabled compared to people with neurological disorders. Unlike previous literature, focused on increasing social support as the origin of improving disability, this study suggested that interventions improving day-to-day functioning or maladaptive personality styles might also have an effect on the way people perceive social support. Future longitudinal research, however, is warranted to explore causality.

    2014-01-01

    Acupuncture and moxibustion, which medical doctors are licensed by the government of Japan to perform, can improve the psychological relationship between doctors and patients, especially when it is disturbed by a “game”, a dysfunctional interpersonal interaction that is repeated unintentionally. This advantage is due to the essential properties of acupuncture and moxibustion. Acupuncture and moxibustion are helpful in treating somatoform disorders, especially musculoskeletal symptoms. In Japan, a holistic acupuncture and moxibustion therapy called Sawada-style has been developed. This is based on fundamental meridian points that are considered to have effects on central, autonomic nervous, immune, metabolic, and endocrine systems to regulate the whole body balance. In addition, some of the fundamental points have effects on Qi, blood, and water patterns associated with major depression, generalized anxiety disorder, eating disorders, and somatoform disorders. The fixed protocol of Sawada-style would be suitable for large-scale, randomized, controlled studies in the future. Recent systematic reviews indicate that electroacupuncture would be a useful addition to antidepressant therapy for some symptoms accompanying fibromyalgia. Acupuncture and moxibustion are also recommended for irritable bowel syndrome, instead of Western drug therapy. Surprisingly, the dorsal prefrontal cerebral cortex, which is associated with a method of scalp acupuncture applied for gastrointestinal disorders, has been found to be activated in patients with irritable bowel syndrome. It is quite possible that regulation of this cortical area is related to the effect of scalp acupuncture. This acupuncture method can be effective not only for irritable bowel syndrome but also for other stress-related gastrointestinal disorders. PMID:24456818

    2010-01-01

    Abstract Obsessive-compulsive disorder (OCD) and related conditions including Tourette's disorder (TD) are chronic, relapsing disorders of unknown etiology associated with marked impairment and disability. Associated immune dysfunction has been reported and debated in the literature since the late 80s. The immunologic culprit receiving the most interest has been Group A Streptococcus (GAS), which began to receive attention as a potential cause of neuropsychiatric symptoms, following the investigation of the symptoms reported in Sydenham's chorea (SC) and rheumatic fever, such as motor tics, vocal tics, and both obsessive-compulsive and attention deficit/hyperactivity symptoms. Young children have been described as having a sudden onset of these neuropsychiatric symptoms temporally associated with GAS, but without supporting evidence of rheumatic fever. This presentation of OCD and tics has been termed pediatric autoimmune neuropsychiatric disorders associated with Streptococcus (PANDAS). Of note, SC, OCD, and TD often begin in early childhood and share common anatomic areas—the basal ganglia of the brain and the related cortical and thalamic sites—adding support to the possibility that these disorders might share a common immunologic and/or genetic vulnerability. Relevant manuscripts were identified through searches of the PsycINFO and MedLine databases using the following keywords: OCD, immune, PANDAS, Sydenham chorea, Tourette's disorder Group A Streptococcus. Articles were also identified through reference lists from research articles and other materials on childhood OCD, PANDAS, and TD between 1966 and December 2010. Considering the overlap of clinical and neuroanatomic findings among these disorders, this review explores evidence regarding the immunobiology as well as the relevant clinical and therapeutic aspects of TD, OCD, and PANDAS.

    This study assessed costs among patients with bipolar disorder for treatment related to bipolar disorder and to comorbid conditions. Risk factors associated with costs were also assessed. Data (January 1998 to December 2002) were from a seven-state Medicaid managed care claims database for 13,471 patients who had received a diagnosis of bipolar disorder, most of whom received medications. Each medical claims cost was adjusted by the medical component of the Consumer Price Index as the dollar value in 2002. In a Poisson regression analysis, treatment costs per enrollment month were regressed on patient's age, gender, medications, and clinical comorbidities. Bipolar disorder treatment accounted for 30% of costs and comorbid disorders for 70%. Key cost components were inpatient care (35%), outpatient care (16%), prescriptions (13%), and physician encounters (11%). Patients with bipolar disorder received a variety of medications: lithium, 13%; anticonvulsants, 35%; second-generation antipsychotics, 24%; first-generation antipsychotics, 22%; and antidepressants, 42%. Compared with the costs for patients receiving antidepressants alone or no medication, the high costs for bipolar disorder treatment and overall treatment were associated with use of second-generation antipsychotics (rate ratio [RR]=1.71, 95% confidence interval [CI]=1.58-1.86 and RR=1.26, CI=1.18-1.34, respectively) and use of anticonvulsants (RR=1.37, CI=1.26-1.48 and RR=1.06, CI=1.00-1.12). Higher costs were significantly associated with key comorbidities, such as drug abuse (RR=1.58, CI=1.47-1.70), cerebral-vascular disease (RR=1.72, CI=1.51-1.94), ischemic heart disease (RR=1.47, CI=1.30-1.66), and hypertension (RR=1.44, CI=1.33-1.56). Cost-containment efforts may need to manage or prevent key comorbidities among patients with bipolar disorder and to evaluate the association between antipsychotic use and treatment outcomes and hospital services.

    Seasonal and perennial allergic conjunctivitis are IgE-mediated, hypersensitivity conditions characterized by ocular pruritus, epiphora, and hyperemia. Proper diagnosis is usually made clinically based on history and physical examination. Diagnostic procedures are rarely necessary. Non-pharmacological measures, such as environmental modification and proper eye care, should be considered for all patients with allergic conjunctivitis. Pharmacological interventions may also be required. Milder cases can be treated with short-term topical ophthalmic therapy such as a decongestant/ antihistamine combination, a mast cell stabilizer, or a multi-action agent. Moderate to severe cases may require longer usage of the above agents and/or the addition of an oral antihistamine. Refractory cases may necessitate the use of topical ophthalmic corticosteroids and topical NSAIDs. Immunotherapy, whether via the subcutaneous route or the intranasal route, should be considered in the treatment of persistent severe cases refractory to conventional treatment. Despite all the available therapeutic agents, there continues to be a constant need to discover more effective ways to treat seasonal and perennial allergic conjunctivitis. This article also discusses recent patents related to the field.

    Work is an important domain of life. It is therefore clear that problems at the workplace and mental disorders will have negative interactions. Job-related anxieties are of special importance as any workplace causes or intensifies anxiety by its very nature. A common final pathway of mental disorders in general and workplace-related anxieties in particular is workplace phobia. Similarly to agoraphobia, it is characterised by panic when approaching or even thinking of the stimulus, in this case the workplace. Workplace phobia has serious negative consequences for the further course of illness. It impairs the ability to work, and can lead to sick leave and early retirement. It requires special therapeutic interventions. This paper describes workplace-related anxieties and workplace phobia and gives a conceptual framework for their understanding.

    2014-02-24

    The amygdala is related with the recognition of the emotional meaning of stimuli, long-term memory, the orientation of social stimuli and the perception of gaze orientation. It plays a fundamental role in the recognition of faces, especially those expressing fear, and makes it possible to comprehend different emotional states, which will facilitate an appropriate social cognition. Dysfunctions of the amygdala have been associated to a number of different neurodevelopmental disorders as well as neurocognitive and behavioural disorders in specific neurogenetic entities. A number of studies focused on the amygdalic complex have allowed researchers to understand many pathophysiological aspects and to formulate new hypotheses regarding their origins. Given that the disorders or conditions in which the role of the amygdala has been evoked are becoming increasingly more extensive, this article refers the reader to those that have aroused the most interest in recent years. Thus, they can be divided into two groups: developmental and behavioural disorders (autism, anxiety disorders, bipolar disorder, alexithymia and anorexia nervosa) and specific neurogenetic entities (fragile X, Rett, Prader-Willi and Williams syndromes), in which structural or dysfunctional alterations have been observed that may be related with their neurocognitive and behavioural symptoms. It is important to remember that the amygdala is a highly connected structure that forms truly functional networks and has been associated to different disorders with varied explanations and includes several different pathophysiological phenomena. Its role must not, therefore, be simplified in a reductionistic manner, but also placed upon a hierarchy of dysfunctions in other areas that interact with it.

    Gluten is one of the most abundant and widely distributed components of food in many areas. It can be included in wheat, barley, rye, and grains such as oats, barley, spelt, kamut, and triticale. Gluten-containing grains are widely consumed; in particular, wheat is one of the world's primary sources of food, providing up to 50% of the caloric intake in both industrialized and developing countries. Until two decades ago, celiac disease (CD) and other gluten-related disorders were believed to be exceedingly rare outside of Europe and were relatively ignored by health professionals and the global media. In recent years, however, the discovery of important diagnostic and pathogenic milestones led CD from obscurity to global prominence. In addition, interestingly, people feeding themselves with gluten-free products greatly outnumber patients affected by CD, fuelling a global consumption of gluten-free foods with approximately $2.5 billion in United States sales each year. The acknowledgment of other medical conditions related to gluten that has arisen as health problems, providing a wide spectrum of gluten-related disorders. In February 2011, a new nomenclature for gluten-related disorders was created at a consensus conference in London. In this review, we analyse innovations in the field of research that emerged after the creation of the new classification, with particular attention to the new European Society for Paediatric Gastroenterology, Hepatology and Nutrition guidelines for CD and the most recent research about non-celiac gluten sensitivity.

    1995-02-01

    In a model for mucosal mast cells (RBL-2H3 cells) a set H1-antagonist derived anti-allergic drugs containing a diphenylmethyl piperazinyl moiety was examined for their ability to inhibit release of the mediator beta-hexosaminidase. Cells were activated with antigen or the calcium ionophore A23187, whether or not in combination with the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA). Oxatomide, hydroxyzine and cetirizine inhibit the antigen induced beta-hexosaminidase release. The release triggered by A23187, whether or not in combination with TPA is hardly influenced by the compounds. A biphasic dependence of the inhibition of exocytosis in RBL cells on lipophilicity is observed with the optimum at log P is 5-6. The extremely lipophilic compounds meclozine and buclizine are not active in this model. pH dependence of the effect of the drugs shows that especially the uncharged species are active in inhibiting exocytosis. The investigated compounds show an effect on phase transitions in L-alpha-phosphatidylcholine dipalmitoyl liposomes as assayed with differential scanning calorimetry (DSC). For the less extremely lipophilic compounds the induced changes in the phospholipid membranes increased with lipophilicity. The relation between structural features of the drug and the interaction with phospholipids is discussed in view of the DSC results. We conclude that location of the active drugs at the membrane or the membrane/protein interface is important for the inhibiting activity on exocytosis. This could affect several membrane related processes, which are abundant in the early phases of the IgE-mediated signal transduction process.

    Bipolar disorder is a disabling disease that involves a significant economic costs to the health system, making it is essential to investigate possible early predictors such as changes in sleep-wake cycle in high-risk populations. To review the available literature on alterations in the sleep-wake cycle and circadian rhythm in patients with bipolar disorder and their first degree relatives. A literature search was performed in the data bases, Access Medicine, ClinicalKey, EMBASE, JAMA, Lilacs, OVID, Oxford Journals, ScienceDirect, SciELO, APA y PsycNET. Articles in both English and Spanish were reviewed, without limits by study type. Actigraphy is a non-invasive, useful method for assessing sleep-wake cycle disturbances in the active phases of bipolar disorder, and during euthymia periods. Actigraphy showed good sensitivity to predict true sleep, but low specificity, compared with polysomnography. Although studies in bipolar offspring and relatives are scarce, they show sleep changes similar to bipolar patients. Actigraphy may be a good screening tool of sleep/wake cycle in patients with bipolar disorders, because it is economic, non-invasive and sensitive. Longitudinal studies are required to evaluate its potential use as a risk marker. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

    Drug-related movement disorders (DRMDs) reduce quality of life and contribute to medication noncompliance of patients with psychotic disorders. Little is known about the epidemiology of DRMDs in relatively young patients a few years after onset of psychosis. This is an important period to study, as the impact of the antipsychotic treatment on the long-term potentiation of the neural pathways associated with psychotic disorders and DRMDs is still minimal. This study investigated the prevalence, incidence, persistence, and clinical correlates of DRMDs in patients during their first years after disease onset. The Genetic Risk and Outcome of Psychosis study is a longitudinal study of 1120 relatively young patients with nonaffective psychosis and a mean age and illness duration of 27 and 4 years, respectively. The following drug-related movement disorders were assessed at baseline and at the 3-year follow-up: parkinsonism, akathisia, tardive dyskinesia, and tardive dystonia. We determined prevalence, incidence, and persistence and investigated clinical correlates at and over the baseline and follow-up assessment. Patients' mean age and illness duration at baseline were 27.1 and 4.3 years, respectively. In 4 patients, 1 developed a DRMD over the 3-year study period. Prevalence, incidence, and persistence rates were highest for parkinsonism (32%, 21%, and 53%) followed by akathisia (9%, 5%, and 17%) and tardive dyskinesia (4%, 3%, and 20%). Significant associations were found between DRMDs and the patients' age, IQ, and psychopathology. The prevalence, persistence, and incidence of DRMDs in this sample were high despite the relatively young age, recent onset of the disorder, and treatment primarily with second-generation antipsychotics. These findings emphasize that screening, diagnosis, and treatment of DRMDs are still important.

    Obsessive-compulsive disorder (OCD) is a highly researched and conceptualized disorder, and yet it remains one of the most debilitating, widespread, and expensive disorders one can be afflicted with [Real, E., Labad, J., Alonso, P., Segalas, C., Jimenez-Murcia, S., Bueno, B., … Menchon, J. M. (2011). Stressful life events at onset of obsessive-compulsive disorder are associated with a distinct clinical pattern. Depression and Anxiety, 28, 367-376. doi:10.1002/da.20792]. Exposure treatments and cognitive-behavioural therapy (CBT) have been largely accepted as best practice for those with OCD, and yet there are still many who are left with "treatment-resistant OCD" [Rowa, K., Antony, M., & Swinson, R.

    Obsessive–compulsive disorder (OCD) is a highly researched and conceptualized disorder, and yet it remains one of the most debilitating, widespread, and expensive disorders one can be afflicted with [Real, E., Labad, J., Alonso, P., Segalas, C., Jimenez-Murcia, S., Bueno, B., … Menchon, J. M. (2011). Stressful life events at onset of obsessive–compulsive disorder are associated with a distinct clinical pattern. Depression and Anxiety, 28, 367–376. doi:10.1002/da.20792]. Exposure treatments and cognitive-behavioural therapy (CBT) have been largely accepted as best practice for those with OCD, and yet there are still many who are left with “treatment-resistant OCD” [Rowa, K., Antony, M., & Swinson, R. (2007). Exposure and response prevention. In C. Purdon, M. Antony, & L. J. Summerfeldt (Eds.), Psychological treatment of obsessive-compulsive disorder: Fundamentals and beyond (pp. 79–109). Washington, DC: American Psychological Association; Foa, E. B. (2010). Cognitive behavioural therapy of obsessive–compulsive disorder. Dialogues of Clinical Neuroscience, 12, 199–207]. Similarly, exposure treatments and CBT have been accepted as best practice for trauma-related distress (i.e. post-traumatic stress disorder; Foa, E. B., Keane, T. M., Friedman, M. J., & Cohen, J. A. (2009). Effective treatments for PTSD: Practice guidelines from the international society for traumatic studies (2nd ed.). New York, NY: The Guilford Press). From a literature review, evidence has been provided that demonstrates a high prevalence rate (30–82%) of OCD among individuals with a traumatic history in comparison to the prevalence rate of the general population (1.1–1.8%; [Cromer, K.

    Work-related musculoskeletal disorders (MSDs) have accounted for a significant proportion of work injuries and workers' compensation claims in industrialized nations since the late 1980s. Despite epidemiological evidence for the role of repetition and force in the onset and progression of work-related MSDs, complete understanding of these important occupational health problems requires further elucidation of pathophysiological mechanisms of the tissue response, particularly in the early stage of these disorders. Results from several clinical and experimental studies indicate that tissue microtraumas occur as a consequence of performing repetitive and/or forceful tasks, and that this mechanical tissue injury leads to local and perhaps even systemic inflammation, followed by fibrotic and structural tissue changes. Here we review work linking inflammation and the development of work-related MSDs. We also propose a conceptual framework suggesting the potential roles that inflammation may play in these disorders, and how inflammation may contribute to pain, motor dysfunction, and to puzzling psychological symptoms that are often characteristic of patients with work-related MSDs.

    A 43-year-old woman was referred by her occupational health service with suspected occupational contact dermatitis. In connection with the investigation, a workplace visit was undertaken at her company, which used an adhesive based on pre-polymeric diphenylmethane diisocyanate in one of its units. During the visit, we became aware of six other employees with skin problems who were then referred to our department for investigation. To investigate the seven employees complaining about skin problems. Seven employees were patch tested with a baseline series, an isocyanate series, and a series with work material. Five of seven patients had occupational contact allergy. Four reacted to isocyanate-related test preparations, and one to a cleanser used at the workplace. Workplace visits constitute an important part of an occupational investigation, as they might give a broader picture of the problems at a company. In this case, it was found that 5 of 100 employees currently had or had previously had occupation-related skin problems. Owing to 'healthy worker selection', some of these patients might have been missed if we had not performed a full-scale workplace visit. © 2012 John Wiley & Sons A/S.

    Background Oral administration of bacterial extracts (eg, Broncho-Vaxom (BV)) has been proposed to attenuate asthma through modulating Treg cells. However, the underlying mechanism has not been fully characterized. This study sought to assess the effects of oral administration of BV on GSK-3β expression and Treg cells in ovalbumin (OVA)-induced asthmatic mice models. Method Asthmatic mice models were established with OVA challenge and treated with oral administration of BV. Next, infiltration of inflammatory cells including eosinophil and neutrophils, mucous metaplasia, levels of Th1/Th2/Treg-typed cytokines and expression of GSK3β and Foxp3 were examined in asthmatic mice models by histological analysis, Bio-Plex and western blot, respectively. Moreover, the frequencies of Treg cells were evaluated in cultured splenocytes by flow cytometry in the presence of BV or GSK3β siRNA interference. Results We found significant decrease of infiltrated inflammatory cells in bronchoalveolar lavage fluid (BALF) in asthmatic mice models after oral administration of BV. Oral administration of BV was shown to significantly suppress mucus metaplasia, Th2-typed cytokine levels and GSK3β expression while increasing Foxp3 production in asthmatic mice models. Moreover, BV significantly enhanced GSK3β-related expansion of Treg cells in cultured spleen cells in vitro. Conclusion Our findings provide evidence that oral administration of BV is capable of attenuating airway inflammation in asthmatic mice models, which may be associated with GSK3β-related expansion of Treg cells.

    This study examined the temporal sequencing of eating and anxiety disorders to delineate which anxiety disorders increase eating disorder risk and whether individuals with eating disorders are at greater risk for particular anxiety disorders. The sample was drawn from the Oregon Adolescent Depression Project. Temporal relations between specific eating and anxiety disorders were examined after controlling for relevant variables (e.g., mood disorders, other anxiety disorders) over 14 years. After excluding those with anorexia nervosa (AN) in adolescence (T1), OCD was the only T1 anxiety disorder to predict AN by age 30 (T4). No T1 anxiety disorder was associated with T4 bulimia nervosa (BN). Although T1 AN did not increase risk of any T4 anxiety disorder, T1 BN appeared to increase risk for social anxiety and panic disorders. Evidence that eating disorders may have differential relations to particular anxiety disorders could inform prevention and treatment efforts. PMID:20185151

    Scope Birch pollen associated allergy to mung bean sprouts is caused by cross-reactivity between the birch pollen allergen Bet v 1 and the mung bean allergen Vig r 1. We aimed to determine the allergenicity of the cytokinin-specific binding protein from mung bean (Vig r 6), another allergen related to Bet v 1 with only 31% sequence identity. Methods and results Bet v 1, Gly m 4, Vig r 1, and Vig r 6 were produced in Escherichia coli. In an ELISA, 73 and 32% of Bet v 1-sensitized birch-allergic patients’ sera (n = 60) showed IgE binding to Vig r 1 and Vig r 6, respectively. Of 19 patients who reported allergic reactions or had positive prick-to-prick tests to mung bean sprouts, 79% showed IgE binding to Vig r 1 and 63% showed IgE binding to Vig r 6. Bet v 1 completely inhibited IgE binding to both mung bean allergens. Vig r 6 showed partial cross-reactivity with Vig r 1 and activated basophils sensitized with mung bean allergic patients’ sera. Conclusion We demonstrated IgE cross-reactivity despite low sequence identity between Vig r 6 and other Bet v 1-related allergens. Thus, IgE binding to Vig r 6 may contribute to birch pollinosis-associated mung bean sprout allergy. PMID:23996905

    There are many challenges to conducting valid epidemiological research of work-related musculoskeletal disorders and interpreting reports describing the results. In particular, these concern the basic study design, selection of subjects, measurement of exposure and outcome, control of confounding and the limitations of workers' compensation data systems. Researchers and people interested in the research results need to be aware of the major potential problems and pay careful attention to them when designing, conducting and using the results of such research.

    The internet age bears new challenges that include health risks. It is agreed that excessive internet use may reach pathological levels. However, the concept of internet addiction lacks specificity and, therefore, warrants studies on its diagnostic and etiologic classification. This study was conducted to characterize the novel DSM-5 criteria for internet gaming disorder and the adapted criteria for the "social network disorder". Based on the established association of handedness and substance use disorders, we also explored whether internet use related to laterality. For this study, 3,287 volunteers participated in the online survey and gave particulars concerning their internet use in general, internet gaming and use of social networks, laterality markers (hand, foot, eye, ear, rotational preference in gymnastics, and head turning asymmetry) and health status. Of the participants, 1.1 % fulfilled the criteria for internet gaming disorder, and 1.8 % fulfilled the criteria for social network disorder. The applied criteria were highly correlated with the time spent on the respective internet activities (p < 4 × 10(-56)). The analyses of comorbidity and working hours support the thresholds of 5/9 criteria and ≥30 h/week spent on the internet for the classification as pathological (p < 5 × 10(-2)). Moreover, we found that left-handedness related to more affirmed criteria and longer times spent on social networks (p ≤ 4 × 10(-2)). The provided criteria proved to be user-friendly, comprehensible and well accepted. The results contribute to a better understanding of pathological internet gaming and social network use and provide evidence that biological markers of substance use disorders are involved in internet addiction.

  11. Occupational Respiratory Allergic Diseases in Healthcare Workers.

    2016-11-01

    Healthcare workers (HCWs) are exposed to a range of high and low molecular weight agents that are allergic sensitizers or irritants including cleaners and disinfectants, natural rubber latex, and various medications. Studies have shown that exposed HCWs are at risk for work-related rhinitis and asthma (WRA). Work-related rhinitis may precede development of WRA and should be considered as an early marker of WRA. Avoidance of causative exposures through control strategies such as elimination, substitution, engineering controls, and process modification is the preferred primary prevention strategy for preventing development of work-related allergic diseases. There is limited evidence for the effectiveness of respirators in preventing occupational asthma. If sensitizer-induced WRA is diagnosed, it is important to avoid further exposure to the causative agent, preferably by more rigorous application of exposure control strategies to the workplace. This review focuses on allergic occupational respiratory diseases in HCWs.

    Background Theoretical and anecdotal support for the role of shame in obsessive compulsive related disorders (OCRDs) is prominent. Developing our understanding of shame’s role in OCRDs is important to building knowledge about this new diagnostic category. This review aims to consolidate our understanding of shame in each OCRD, through summarizing existing clinical, conceptual, and empirical work. Methods We provide an overview of shame, its measurement considerations, and a full review of 110 articles addressing shame in OCRDs. Results General shame and shame about having a mental illness are the broadest types of shame relevant to OCRDs; symptom-based shame and body shame may be more specific to OCRDs. In OCD, violent, sexual, or blasphemous obsessions may trigger symptom-based shame. In trichotillomania (TTM) and skin picking (SP), symptom-based shame may be related to pulling, picking, and post-pulling/picking behaviors. In hoarding disorder, symptom-based shame may accompany beliefs about being defective due to living with clutter. Body shame appears inherent to body dysmorphic disorder, while in TTM and SP it may arise as a secondary response to damage resulting from body focused repetitive behaviors. Limitations Much of the current knowledge on shame in OCRDs comes from anecdotal, case, and conceptual work. Empirical studies do not always assess specific types of shame, instead assessing shame as a general construct. Conclusions Shame is closely related to OCRDs. Clinical and research recommendations drawing from the literature are provided. PMID:25299438

    Background Interactions between characteristics of bipolar and Axis II cluster B disorders are clinically and diagnostically challenging. Characteristics associated with personality disorders may be dimensional aspects of bipolar disorder. We investigated relationships among antisocial personality disorder (ASPD) or borderline personality disorder symptoms, impulsivity, and course of illness in bipolar disorder. Methods Subjects with bipolar disorder were recruited from the community. Diagnosis was by Structured Clinical Interview for DSM-IV (SCID-I and –II), psychiatric symptom assessment by the Change version of the Schedule for Affective Disorders and Schizophrenia (SADS-C), severity of axis II symptoms by ASPD and borderline personality disorder SCID-II symptoms, and impulsivity by the Barratt Impulsiveness Scale (BIS-11). Results ASPD and borderline symptoms were not related to clinical state or affective symptoms. Borderline symptoms correlated with BIS-11 impulsivity scores, and predicted history of suicide attempts independently of the relationship to impulsivity. ASPD symptoms were more strongly related to course of illness, including early onset, frequent episodes, and substance-related disorders. These effects persisted after allowance for gender and substance-use disorder history. Conclusions Personality disorder symptoms appear to be dimensional, trait-like characteristics of bipolar disorder. ASPD and Borderline symptoms are differentially related to impulsivity and course of illness. PMID:22835849

  15. Tregs and allergic disease

    Allergic diseases such as asthma, rhinitis, and eczema are increasing in prevalence and affect up to 15% of populations in Westernized countries. The description of Tregs as T cells that prevent development of autoimmune disease led to considerable interest in whether these Tregs were also normally involved in prevention of sensitization to allergens and whether it might be possible to manipulate Tregs for the therapy of allergic disease. Current data suggest that Th2 responses to allergens are normally suppressed by both CD4+CD25+ Tregs and IL-10 Tregs. Furthermore, suppression by these subsets is decreased in allergic individuals. In animal models, Tregs could be induced by high- or low-dose inhaled antigen, and prior induction of such Tregs prevented subsequent development of allergen sensitization and airway inflammation in inhaled challenge models. For many years, allergen-injection immunotherapy has been used for the therapy of allergic disease, and this treatment may induce IL-10 Tregs, leading to both suppression of Th2 responses and a switch from IgE to IgG4 antibody production. Improvements in allergen immunotherapy, such as peptide therapy, and greater understanding of the biology of Tregs hold great promise for the treatment and prevention of allergic disease.

    Epidemiologically there is an association between allergic rhinitis and asthma due to a common inflammatory process. Asthma can affect 40% of the patients with rhinitis and 80% of asthmatics present rhinitis. The relationship between the two diseases is explained by the term of "a united airway". Some patients with allergic rhinitis have nonspecific bronchial hyper-responsiveness, specially during the exacerbation stage. These patients have a unique physiologic characteristic that differs from the asthmatic and healthy subjects developing bronchoconstriction not related to clinical bronchospasm, therefore, allergic rhinitis is considered a risk factor for the asthma development. To determine if there is bronchial hyper-responsiveness in patients with allergic and not allergic rhinitis, by correlating with the eosinophilia in nasal mucosa. We studied a total of 32 patients with an age range from 18 to 38 years, of both sexes (11 men and 17 women) of the Hospital Regional Lic. Adolfo Lopez Mateos, ISSSTE. They were submitted to clinical history, laboratory studies (blood count cell, serum IgE levels, eosinophils of nasal mucosa), roentgenograms (paranasal sinus and esophagus-gastroduodenal series) and allergy skin tests with 32 allergens. It was taken biopsy of nasal mucosa for the search of eosinophils and it was carried out bronchial challenge with distilled water. Twenty-eight patients concluded the study, they were divided in two groups: a group of 15 patients with diagnosis of allergic rhinitis and another group of 13 patients with diagnosis of non allergic rhinitis. Fifty-six spirometry studies were performed and only 4 patients (26.6%) with diagnosis of allergic rhinitis presented fall of the FEV1 in the bronchial challenge in comparison with the group of non allergic rhinitis in which there were no changes in the FEV1 later to the bronchial challenge. This difference was statistically significant (-4.3 and 0.15, respectively with a p < 0.0370, CI 95

    Although previous research has supported the importance of anxiety as an etiological and maintenance factor for eating disorders, the specific mechanisms are not well understood. The role of anxiety in the context of eating behavior is especially unclear. The purpose of this study was to identify anxiety-eliciting eating situations and anxiety management strategies patients use to mitigate anxiety experienced in the context of eating as determined by diagnostic groups and symptom patterns. Fifty-three eating disorder outpatients were administered the Eating and Anxiety Questionnaire (EAQ) and the Eating Disorder Diagnostic Scale. Ratings indicated significant anxiety in most eating situations, whereas management strategies were more limited yet regularly employed. Factor analysis of the EAQ revealed a 6-factor solution for anxiety management strategies and a 4-factor solution for anxiety-eliciting situations. These results indicate patients with eating disorders report high levels of anxiety associated with eating behaviors but utilize limited yet consistent anxiety management strategies. Effective intervention strategies for managing eating-related anxiety should be incorporated into treatment and may need to be specified for different diagnostic subgroups.

    The Marfan syndrome is an inherited disorder of the connective tissue which is mainly caused by a mutation in the fibrillin-1 gene. The defect in the connective tissue protein can lead to several organ dysfunctions. For the life expectancy, the cardiovascular aspect is of paramount importance. Patients with Marfan syndrome may develop aortic aneurysms and valvular heart defects. The risk of aortic aneurysms consists in the development of aortic dissection or rupture with their fatal consequences. Besides the cardiovascular manifestation, the skeletal and ocular system can also be affected. The skeletal manifestation is often characterised by long limbs, arachnodactyly, and abnormal joint flexibility along with other signs. Patients may also have dislocated lenses, ectasia of the dural sac, stretch marks, spontaneous pneumothorax, recurrent hernia, or a family history suspicious for Marfan. During the past years, other related connective tissue disorders with analogous organ manifestation have been described (e.g., Loeys-Dietz syndrome). In this article we present the basic knowledge about these connective tissue disorders, and we mention new insights in the recently explored pathophysiology of the disorder which is a possible target for future medical treatment options. Furthermore, recent new concepts for the prophylactic treatment of the aortic manifestation are explained.

    The endocannabinoid system plays an important role in the control of emotions, and its dysregulation has been implicated in several psychiatric disorders. The most common self-reported reason for using cannabis is rooted in its ability to reduce feelings of stress, tension, and anxiety. Nevertheless, there are only few studies in controlled clinical settings that confirm that administration of cannabinoids can benefit patients with a post-traumatic stress disorder (PTSD). There are considerable encouraging preclinical data to suggest that endocannabinoid-targeted therapeutics for anxiety disorders should continue. In this review, we will describe data supporting a role for the endocannabinoid system in preventing and treating anxiety-like behavior in animal models and PTSD patients. Cannabinoids have shown beneficial outcomes in rat and mouse models of anxiety and PTSD, but they also may have untoward effects that discourage their chronic usage, including anxiogenic effects. Hence, clinical and preclinical research on the endocannabinoid system should further study the effects of cannabinoids on anxiety and help determine whether the benefits of using exogenous cannabinoids outweigh the risks. In general, this review suggests that targeting the endocannabinoid system represents an attractive and novel approach to the treatment of anxiety-related disorders and, in particular, PTSD.

    Allergic diseases are a global public health issue affecting millions of persons around the world. However, full understanding of the molecular basis of this group of chronic inflammatory disorders remains rather elusive. Recently, the role of carbohydrates on allergens and their counterstructures on antigen-presenting cells (lectins) have been highlighted as crucial factors in allergen sensitization, which culminates in TH2 cell differentiation and the production of deleterious specific IgE antibodies. Here we review recent progress on the role of different lectins in patients with type I hypersensitivity or allergy, their interplay with other determinants of allergenicity, and ways of developing therapeutic modalities against newly identified targets.

    The aim of the study was to evaluate the efficacy and duration of two doses of dimethindene, in a sustained release pellet formulation, with a standardized grass pollen provocation model (Vienna Challenge Chamber, VCC). The study of 12 grass pollen-allergic volunteers (verified by case history, skin prick test and RAST) was carried out in a placebo-controlled, double-blind, cross-over design. 12 h before a 4-hour continuous challenge with permanent 1,000 Dactylis grass pollen/m3 of air in the VCC, 4 or 8 mg of dimethindene (Fenistil pellets) or an identically appearing placebo was administered in three sessions. Nasal flow and resistance, nasal secretion and subjective symptoms were recorded at 15-min intervals during this long-term challenge under reproducible conditions. In comparison to placebo, dimethindene leads to a statistically significant reduction (p < 0.05) in nasal response and clinical symptoms for at least 16 h after treatment. The efficacy of 8 mg dimethindene was superior to that of 4 mg dimethindene; however, the differences between both active treatments were not statistically significant. Therefore 4 mg dimethindene once a day is adequate for usual pollinotic disease conditions.

    The frequency distribution of nonparaphilic hypersexual behaviors was investigated in an outpatient sample of 206 consecutively evaluated males seeking help for sexual impulsivity disorders (SIDs), either paraphilia-related disorders (PRD; n = 63) or paraphilias (PA; n = 143). Paraphilia-related disorders associated with help-seeking behaviors included compulsive masturbation (sample prevalence, 69%), protracted heterosexual or homosexual promiscuity (51%), pornography dependence (50%), telephone-sex dependence (24%), and severe sexual desire incompatibility (12%). Eighty-six percent of the PA sample reported at least one lifetime PRD. The subgroup of males with both PAs and lifetime PRDs (n = 123) self-reported the greatest number of lifetime SIDs, the highest incidence of physical and sexual abuse, the fewest years of completed education, and the highest likelihood of current unemployment or disability. As well, the subgroup of males with PAs but no lifetime PRDs (n = 20) self-reported the fewest lifetime SIDs; this subgroup was not statistically different from the PRD group on these aforementioned variables. These data suggest that social disadvantage, as assessed in this sample, is associated with the cumulative incidence of SIDs but not necessarily with the diathesis to develop paraphilic disorders.

    Introduction. Benchalokawichian (BCW), a Thai traditional herbal formulation, has long been used as antipyretic and to treat skin disorders. It comprises roots from five herbs: Ficus racemosa, Capparis micracantha, Clerodendrum petasites, Harrisonia perforata, and Tiliacora triandra. This polyherbal remedy has recently been included in the Thailand National List of Essential Medicines (Herbal Products list). Methodology. A Bioassay-guided fractionation technique was used to evaluate antiallergy activities of crude extracts, and those obtained by the multistep column chromatography isolation of pure compounds. Inhibitory effect on the release of β-hexosaminidase from RBL-2H3 cells was used to determine antiallergic activity. Results. Two pure compounds from BCW formulation showed higher antiallergic activity than crude or semipure extracts. Pectolinarigenin showed the highest antiallergic activity, followed by O-methylalloptaeroxylin, with IC50 values of 6.3 μg/mL and 14.16 μg/mL, respectively. Moreover, the highest activities of pure compounds were significantly higher than chlorpheniramine (16.2 μg/mL). Conclusions. This study provides some support for the use of BCW in reducing itching and treatment of other skin allergic disorders. The two isolated constituents exhibited high antiallergic activity and it is necessary to determine their mechanism of action. Further phytochemical and safety studies of pure compounds are required before development of these as antiallergy commercial remedies. PMID:25580152

    Summary Objective FOXG1-related disorders are associated with severe intellectual disability, absent speech with autistic features, and epilepsy. Children with deletions or intragenic mutations of FOXG1 also have postnatal microcephaly, morphologic abnormalities of the corpus callosum, and choreiform movements. Duplications of 14q12 often present with infantile spasms, and have subsequent intellectual disability with autistic features. Long term epilepsy outcome and response to treatment has not been studied systematically in a well-described cohort of subjects with FOXG1-related disorders. We report on the epilepsy features and developmental outcome of 23 new subjects with deletions or intragenic mutations of FOXG1, and 7 subjects with duplications. Methods Subjects had either chromosomal microarray or FOXG1 gene sequencing performed as part of routine clinical care. Development and epilepsy follow-up data were collected from medical records from treating neurologists and through telephone parental interviews using standardized questionnaires. Results Epilepsy was diagnosed in 87% of the subjects with FOXG1-related disorders. The mean age of epilepsy diagnosis in FOXG1 duplications was significantly younger than those with deletions/intragenic mutations (p=0.0002). All of the duplication FOXG1 children with infantile spasms responded to hormonal therapy and only one required long-term anti-epileptic therapy. In contrast, more children with deletions/intragenic mutations required anti-epileptic drugs on follow-up (p<0.0005). All subjects with FOXG1-related disorders had neurodevelopmental disabilities after 3 years of age, regardless of the epilepsy type or intractability of seizures. All had impaired verbal language and social contact, and three duplication subjects were formally diagnosed with autism. Subjects with deletion/intragenic mutations however had significantly worse ambulation (p=0.04) and functional hand use (p<0.0005). Significance Epilepsy and

    A gluten-free diet (GFD) is recommended for all patients with coeliac disease (CD). The spectrum of gluten-related disorders in the early 1980s was simple: CD and dermatitis herpetiformis. In the last few years, wheat allergy, gluten ataxia and noncoeliac gluten sensitivity have become new gluten-related topics. Adherence to GFDs in CD is limited and factors influencing adherence are poorly understood. Noncoeliac gluten sensitivity has stimulated the GFD food industry not only in Australia but all over the world. This article provides an overview of GFD in daily practice.

    Objective Research has demonstrated the effect of adverse childhood experiences (ACE) on later physiologic function and illness development. In the urologic literature, the relationship between bladder dysfunction and neuropsychiatric disorders is well documented. Observations in pediatric urology clinical practice suggest that a blend of these two areas of research can inform care of patients with voiding dysfunction. Methods Retrospective review of 216 patients seen in a single pediatric urology clinic by a single provider over a 24-month period. A descriptive, correlational study design was used to assess the extent to which ACEs and neuropsychiatric disorders affected resolution of symptoms when patients were treated with a bowel and bladder retraining program. Patients were selected using diagnostic codes related to voiding dysfunction and a retrospective chart review was conducted. Results A majority of patients who were seen for voiding dysfunction (60%) had at least one psychosocial factor. There is a greater prevalence of ACEs (51%) than neuropsychiatric disorders (25%). Children with psychosocial factors dropped out of treatment at a higher rate than those with no factors. When factors were looked at separately, neuropsychiatric disorders were more likely to impede treatment progress than ACEs. Conclusions ACEs and neuropsychiatric disorders affect patients’ ability to make progress with bowel and bladder retraining and to stay in treatment. Efforts specifically aimed at maintaining therapeutic relationships with patients who have ACEs are needed to fully treat this group, which typically has a high drop-out rate but high rate of resolution if they are able to stay involved in treatment.

    Ocular allergy is an inflammatory response of the conjunctival mucosa that also affects the cornea and eyelids. Allergic conjunctivitis includes seasonal allergic conjunctivitis (SAC), perennial allergic conjunctivitis (PAC), vernal keratoconjunctivitis (VKC), atopic keratoconjunctivitis (AKC) and giant papillary conjunctivitis (GPC). In general, allergic conditions involve mast cell degranulation that leads to release of inflammatory mediators and activation of enzymatic cascades generating pro-inflammatory mediators. In chronic ocular inflammatory disorders associated with mast cell activation such as VKC and AKC constant inflammatory response is observed due to predominance of inflammatory mediators such as eosinophils and Th2-generated cytokines. Antihistamines, mast-cell stabilizers, non-steroidal anti-inflammatory agents, corticosteroids and immunomodulatory agents are commonly indicated for the treatment of acute and chronic allergic conjunctivitis. In recent years newer drug molecules have been introduced in the treatment of allergic conjunctivitis. This article reviews recent patents and emerging therapeutics in the treatment of allergic conjunctivitis. PMID:21171952

    Howden, Colin W

    2004-09-06

    Dysphagia affects a large and growing number of individuals in the United States, particularly the elderly and those who are neurologically impaired. Swallowing difficulties may be due to age-related changes in oropharyngeal and esophageal functioning as well as central nervous system diseases such as stroke, Parkinson disease, and dementia. Among institutionalized individuals, dysphagia is associated with increased morbidity and mortality. An appreciation of the physiology of swallowing and the pathophysiology of dysphagia is necessary for proper patient management. Careful history, physical examination, and evaluation of radiologic and endoscopic studies should differentiate oropharyngeal and esophageal etiologies of dysphagia and distinguish mechanical (anatomic) disorders from functional (motor) disorders. A significant percentage of patients with dysphagia have concomitant acid-related disorders that are managed best with proton pump inhibitor (PPI) therapy. Three of the currently available PPIs are manufactured as capsules containing enteric-coated granules that may be mixed with soft foods or fruit juices before oral administration to those with swallowing difficulties. In addition, omeprazole and lansoprazole may be administered via gastrostomy or nasogastric feeding tubes as suspensions in sodium bicarbonate. Novel dosage formulations of lansoprazole that may be appropriate for patients with dysphagia include the commercially manufactured lansoprazole strawberry-flavored enteric-coated granules for suspension and lansoprazole orally disintegrating tablets.

    Purpose of review The understanding of how adrenal function is challenged by the interplay of our genetic and environmental milieu has highlighted the importance of inappropriate cortisol regulation in cardiometabolic disorders. Increased adipose tissue in obesity is associated with hypothalamic-pituitary-adrenal axis over-activation, increased cortisol production at the local tissue level, and probably higher mineralocorticoid receptor activation in certain tissues. Recent findings Due to the clinical resemblance of obesity-related metabolic disorders with the Cushing syndrome, new studies have investigated the intracellular regulation and metabolism of cortisol, new measurements in scalp hair as a tool for long-term exposure and the cortisol-mineralocorticoid receptor pathway. Thus, current and future pharmacological interventions in obesity may include specific inhibition of steroidogenic and regulatory enzymes as well as antagonists of the mineralocorticoid and glucocorticoid receptors. Summary This review highlights recent investigations focusing on the role of dysregulated cortisol physiology in obesity as a potential modifiable mechanism in the pathogenesis of obesity related cardiometabolic disorders.

    Studies of posttraumatic stress disorder (PTSD) in adolescence published from 2000 to 2011 indicate that adolescents are at greater risk of experiencing trauma than either adults or children, and that the prevalence of PTSD among adolescents is 3-57%. Age, gender, type of trauma, and repeated trauma are discussed as factors related to the increased rates of adolescent PTSD. PTSD in adolescence is also associated with suicide, substance abuse, poor social support, academic problems, and poor physical health. PTSD may disrupt biological maturational processes and contribute to the long-term emotion and behavior regulation problems that are often evident in adolescents with the disorder. Recommendations are presented for practice and research regarding the promotion of targeted prevention and intervention services to maximize adolescents' strengths and minimize vulnerabilities. Public policy implications are discussed.

    Pollen is the most common aeroallergen to cause seasonal conjunctivitis. The result of allergen exposure is a strong Th2-mediated response along with conjunctival mast cell degranulation and eosinophilic infiltration. Oleanolic acid (OA) is natural a triterpene that displays strong anti-inflammatory and immunomodulatory properties being an active anti-allergic molecule on hypersensitivity reaction models. However, its effect on inflammatory ocular disorders including conjunctivits, has not yet been addressed. Hence, using a Ragweed pollen (RWP)-specific allergic conjunctivitis (EAC) mouse model we study here whether OA could modify responses associated to allergic processes. We found that OA treatment restricted mast cell degranulation and infiltration of eosinophils in conjunctival tissue and decreased allergen-specific Igs levels in EAC mice. Th2-type cytokines, secreted phospholipase A2 type-IIA (sPLA2-IIA), and chemokines levels were also significantly diminished in the conjunctiva and serum of OA-treated EAC mice. Moreover, OA treatment also suppressed RWP-specific T-cell proliferation. In vitro studies, on relevant cells of the allergic process, revealed that OA reduced the proliferative and migratory response, as well as the synthesis of proinflammatory mediators on EoL-1 eosinophils and RBL-2H3 mast cells exposed to allergic and/or crucial inflammatory stimuli such as RWP, sPLA2-IIA or eotaxin. Taken together, these findings demonstrate the beneficial activity of OA in ocular allergic processes and may provide a new intervention strategy and potential therapy for allergic diseases.

    This review focuses on local allergic rhinitis, a new phenotype of allergic rhinitis, commonly misdiagnosed as nonallergic rhinitis. It has gained attention over last decade and can affect patients from all countries, ethnic groups and ages, impairing their quality of life, and is frequently associated with conjunctivitis and asthma. Diagnosis is based on clinical history, the demonstration of a positive response to nasal allergen provocation test and/or the detection of nasal sIgE. A positive basophil activation test may support the diagnosis. Recent studies have demonstrated that allergen immunotherapy is an effective immune-modifying treatment, highlighting the importance of early diagnosis.

    Apoptosis (cell programmed death) it is a mechanism that implicate a physiological suicide, to keep the cellular homeostasis in big amount of tissues. Fas (APO-1; CD95) system is one of the most important cellular responsible via to induce apoptosis on different tissues. Eosinophillia on peripheral blood and tissues are the main characteristics on allergic like asthma. Eosinophil apoptosis is upper regulated in those diseases by IL-5 y GM-CSF. Corticoids, teophyllin and some macrolids have been used like apoptosis inductors on eosinophills, these could be a novel mechanism to promote a better solution on inflammatory allergic diseases.

    2011-06-01

    Allergic fungal rhinosinusitis is a phenotype of chronic rhinosinusitis with nasal polyposis, characterized by type 1 hypersensitivity to fungi, eosinophilic mucin with fungal hyphae in sinus secretions, and propensity for mucocele formation and bone erosion. Although its differentiation from other forms of chronic polypoid rhinosinusitis with eosinophilic mucin is sometimes problematic, type 1 hypersensitivity is a component of the disease process. Medical and surgical management can be augmented by immunotherapy directed toward the patient's specific allergen sensitivities. The primary rationale for immunotherapy is to control the allergic diathesis that may be contributing to the patient's chronic sinus inflammation. Copyright © 2011 Elsevier Inc. All rights reserved.

    Antimony is used as a flame-retardant in textiles and plastics, in semiconductors, pewter, and as pigments in paints, lacquers, glass and pottery. Subacute or chronic antimony poisoning has been reported to cause sleeplessness. The prevalence of short sleep duration (<7h/night) has been reported to be 37.1% in the general US population, and obstructive sleep apnea (OSA) affects 12-28 million US adults. Insufficient sleep and OSA have been linked to the development of several chronic conditions including diabetes, cardiovascular disease, obesity and depression, conditions that pose serious public health threats. To investigate whether there is an association between antimony exposure and sleep-related disorders in the US adult population using the National Health and Nutrition Examination Survey (NHANES) 2005-2008. We performed multivariate logistic regression to analyze the association of urinary antimony with several sleep disorders, including insufficient sleep and OSA, in adult (ages 20 years and older) participants of NHANES 2005-2008 (n=2654). We found that participants with higher urinary antimony levels had higher odds to experience insufficient sleep (≤6h/night) (OR 1.73; 95%CI; 1.04, 2.91) as well as higher odds to have increased sleep onset latency (>30min/night). Furthermore, we found that higher urinary antimony levels in participants were associated with OSA (OR 1.57; 95%CI; 1.05, 2.34), sleep problems, and day-time sleepiness. In this study, we found that urinary antimony was associated with higher odds to have insufficient sleep and OSA. Because of the public health implications of sleep disorders, further studies, especially a prospective cohort study, are warranted to evaluate the association between antimony exposure and sleep-related disorders.

    Schoolchildren reported their parents' use of aversive control and positive reinforcement contingencies in their educational interventions, as well as parental non-responsiveness to their requests for educational assistance. They also reported their own levels of six dimensions of anxiety disorder-related phenomena. Both parental use of aversive control and non-responsiveness were directly related to overall levels of child anxiety disorder-related behavior; these correlations were more robust than those observed in previous investigations of more diffuse dimensions of parenting style and trait anxiety. Panic disorder/agoraphobia and Generalized anxiety disorder were the dimensions most strongly correlated with both parental aversive control and non-responsiveness, while Compulsive behavior was uniquely uncorrelated with parental non-responsiveness and uniquely correlated with parental use of positive reinforcement contingencies. Differences in the magnitudes of correlations between anxiety disorder-related dimensions and parental educational practices are interpreted in terms of the probable differential effectiveness of their constituent behaviors in terminating parent-mediated negative reinforcers.

The selected 1508 automobile assembly workers from a north car manufacturing company were regarded as the study object. The hazard zone jobs checklist, Nordic musculoskeletal symptom questionnaire (NMQ) and pain questionnaire were used to perform the epidemiological cross-sectional and retrospective survey and study for the General status, awkward ergonomics factors and related influencing factors, and musculoskeletal disorders of workers. The predominant body sites of occurring WMSDs among automobile assembly workers were mainly low back, wrist, neck and shoulders, the predominant workshop section of occurring WMSDs were mostly concentrated in engine compartment, interior ornament, door cover, chassis and debugging section. The predominant body site of WMSDs among engine compartment and chassis section workers was low back, interior ornament workers were low back and wrist, door cover workers was wrist, chassis workers was low back, debugging workers were neck and low back. Neck musculoskeletal disorders had the trend with the increase of a body height; Smoking may increase the occurrence of musculoskeletal disorders. The WMSDs appears to be a serious ergonomic proble assem among automobile assembly workers, predominant occurring site of WMSDs is with different workshop section, its characteristics is quite obvious, probably related to its existing awkward work position or activities. The worker height and smoking habits may be important factors which affect musculoskeletal disorders happen.

    Impulsivity has been consistently associated with pathological gambling (PG), but the diversity of definitions and measures of impulsivity has led to ambiguity with regard to which indices are independently relevant. Toward clarifying this relationship, the current study examined indices from an array of commonly-used impulsivity measures in relation to PG severity in an adult community sample of frequent gamblers (N = 353). These included both survey assessments and behavioral tasks. Using a factor analytic approach, four latent factors were identified among 19 indices and were designated reward sensitivity, punishment sensitivity, delay discounting, and cognitive impulsivity. All four latent variables were positively and independently related to PG severity, albeit at a trend level for cognitive impulsivity in a combined model. These findings reveal four generally independent domains of impulsivity that are related to PG severity, clarify which assessment measures aggregate in each domain, and illustrate the importance of measurement specificity in studying impulsivity in relation to PG and other psychiatric disorders.

    Allergic fungal sinusitis (AFS) is a subtype of eosinophilic chronic rhinosinusitis (CRS) characterized by type I hypersensitivity, nasal polyposis, characteristic computed tomography scan findings, eosinophilic mucus, and the presence of fungus on surgical specimens without evidence of tissue invasion. This refractory subtype of CRS is of the great interest in the pediatric population, given the relatively early age of onset and the difficulty in managing AFS through commercially available medical regimens. Almost universally, a diagnosis of AFS requires operative intervention. Postoperative adjuvant medical therapy is a mainstay in the treatment paradigm of pediatric AFS.

    Musculoskeletal disorders (MSDs), including low back and upper extremity disorders, represent one of the greatest work-related health concerns facing industrialized nations. Recently, two national groups were charged with developing research agendas aimed at increasing our knowledge of the prevention of these disorders. The first agenda, developed by the National Institute for Occupational Safety and Health's (NIOSH) National Occupational Research Agenda (NORA) MSD team, was based on input from several hundred practitioners and safety and health experts representing industry, labor, and academia. The second agenda, developed by the National Research Council (NRC) and the Institute of Medicine's (IOM) National Panel on Musculoskeletal Disorders and the Workplace, was based on input from leading researchers in the fields of medicine, information science, and ergonomics. This paper summarizes the findings of the two groups and compares the two research agendas.

    Health professions like dentistry, nursing and physical therapy have been reported at high risk for developing work-related musculoskeletal disorders. Results of studies conducted in these occupational groups may help formulate prevention strategies. However, no such data among physical therapists has been reported in India. We conducted an online survey among 100 physiotherapists in Delhi. The response rate was 75%. The prevalence of work-related musculoskeletal disorders is found to be high since 92% of them reported to feel some pain after joining physical therapy which affects daily activities and even sometimes forces them to change their work. Physical therapists specialty, gender, furniture used in clinic and duration of patient contact are found to be related to the pain development (p<0.05). We need to emphasize the role of ergonomics and techniques of patient handling in development of work-related pain symptoms.

    The aim of this cross-sectional study was to observe whether environmental factors and phenotypic traits are associated with owner-reported skin problems and with veterinary diagnosed canine atopic dermatitis (CAD). Data were collected using the validated online DOGRISK questionnaire. Out of the data that the questionnaire provides for analysis, focus was first turned towards addressing questions regarding 'Atopy/allergy (skin symptoms)' using a total of 8643 dogs: 1585 dogs with owner-reported allergic/atopic skin symptoms and 7058 dogs without. A subsequent analysis compared dogs with veterinary-verified CAD (n = 322) as a case group against the 7058 dogs without owner-reported skin symptoms. The association between 21 factors related to the environment, canine phenotypes and breed groups within both populations were analysed using univariable and multivariable logistic regression. The environmental factors that showed a significant inverse association with the risk of owner-reported allergic/atopic skin symptoms were as following: whether the dog was living in a detached house, whether there were other dogs in the household, and whether the dog was born in the current household. Having over 50% white colour in the coat and living in an extremely clean household were significantly associated with an increased risk of owner-reported allergic/atopic skin symptoms. The five breeds demonstrating the highest proportion of owner-reported allergic/atopic skin symptoms were West Highland white terrier, Boxer, English bulldog, Dalmatian and French bulldog. The Fédération Cynologique Internationale dog breed groups 3 (Terriers) and 6 (Scent hounds and related breeds) showed a significantly higher risk for owner-reported allergic/atopic skin symptoms than mixed breed dogs.

    Objective To determine prognostic value of acoustic rhinometry in patients with perennial allergic rhinitis (PAR) treated with montelukast in fix combination with desloratidine and to assess effectiveness of this medication on health-related quality of life (HRQL). Study design A randomized, double-blind, prospective and multicentric clinical study. Setting Tertiary university hospitals. Methods Patients 20 years of age and older with PAR were assessed over 3 months of treatment with fix combination of montelukast 10 mg plus desloratidine 5 mg once daily (n = 40). Comparative acoustic rhinometric evaluation was used to compare nasal changes in before and after treatments. For evaluation of HRQL between before and after treatments at the first and third months, the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was used. Results Nasal symptoms and findings including itching, sneezing, discharge, congestion and edema and color change of turbinates have been decreased after treatment. In acoustic rhinometry, minimum cross-sectional area (MCA) measurements and volume results were statistically higher than in before treatment (P < 0.001). Correlation was found that between the volume results and nasal discharged and/or congestion in right nasal passages. In left nasal passages, statistical relation was described between the MCA measurements and itching and/or change of turbinate color (P < 0.05). There was a larger decrease in the overall RQLQ score for the group using montelukast plus desloratidine compared with the pre-treatment scores (P < 0.001). The difference between scores at baseline versus the end of the first and third months for all domains was statically significant (P < 0.001). The treatment difference in change from first month to the end of the third month was statically significant, in favor of the third month, for eye, nose, and non- nose/eye symptoms, sleep, practical problems, emotions and activities that have been limited by nose or eye

    Imidazole dipeptides (ID), such as carnosine (β-alanyl-L-histidine), are compounds widely distributed in excitable tissues of vertebrates. ID are also endowed of several biochemical properties in biological tissues, including antioxidant, bivalent metal ion chelating, proton buffering, and carbonyl scavenger activities. Furthermore, remarkable biological effects have been assigned to such compounds in age-related human disorders and in patients whose activity of serum carnosinase is deficient or undetectable. Nevertheless, the precise biological role of ID is still to be unraveled. In the present review we shall discuss some evidences from clinical and basic studies for the utilization of ID as a drug therapy for age-related human disorders.

    2017-10-01

    The Mood Disorder Questionnaire (MDQ; Hirschfeld et al., 2000) is a widely used screening measure in bipolar disorder research. Although this measure assesses a heterogeneous range of content, only limited prior research utilizing relatively small sample sizes has examined its factor structure. The MDQ's structure was examined in 700 participants reporting current psychiatric treatment. We extended prior structural work on the MDQ by explicating relations between factors and a wide range of psychopathology and personality measures. The MDQ items were best captured by a two-factor structure consisting of dimensions labeled Positive Activation and Negative Activation. These two factors showed very different patterns of associations with personality, other psychopathology, and ratings of significant impairment, the last of which is a requirement for a positive MDQ screen using traditional scoring methods. Our study did not include clinician or informant ratings of bipolar disorder, preventing us from examining associations with such scores. Our findings indicate that although the MDQ items cohere to define a total score, their structure is best modeled by meaningful Positive Activation and Negative Activation factors. Researchers and clinicians should be aware of these distinct sets of MDQ content, as high scorers on Positive Activation are less likely to identify past symptoms as problematic and show distinct clinical profiles from high scorers on Negative Activation.

SRED patients describe eating in an out-of-control manner with preference for high-caloric foods and sometimes with inedible or toxic items. Level of consciousness during SRED episodes ranges from partial consciousness to dense unawareness typical of somnambulistic episodes. SRED is sometimes associated with psychotropic medication, in particular sedative hypnotics, and other sleep disorders, including parasomnias, narcolepsy, and restless legs syndrome. Night eating syndrome (NES) is another important condition in the disordered night-time eating spectrum showing hyperphagia episodes at full arousal from nocturnal sleep without accompanying amnesia. NES could be considered an abnormality in the circadian rhythm of meal timing with a normal circadian timing of sleep onset. The two conditions often overlap and possibly share a common pathophysiology. Studies have suggested that central nervous system serotonin modulation may lead to an effective treatment of NES, while the anti-seizure medication topiramate may be an effective SRED treatment.

    Alzheimer's disease and other related neurodegenerative diseases are highly debilitating disorders that affect millions of people worldwide. Efforts towards developing effective treatments for these disorders have shown limited efficacy at best, with no true cure to this day being present. Recent work, both clinical and experimental, indicates that many neurodegenerative disorders often display a coexisting metabolic dysfunction which may exacerbate neurological symptoms. It stands to reason therefore that metabolic pathways may themselves contain promising therapeutic targets for major neurodegenerative diseases. In this review, we provide an overview of some of the most recent evidence for metabolic dysregulation in Alzheimer's disease, Huntington's disease, and Parkinson's disease, and discuss several potential mechanisms that may underlie the potential relationships between metabolic dysfunction and etiology of nervous system degeneration. We also highlight some prominent signaling pathways involved in the link between peripheral metabolism and the central nervous system that are potential targets for future therapies, and we will review some of the clinical progress in this field. It is likely that in the near future, therapeutics with combinatorial neuroprotective and 'eumetabolic' activities may possess superior efficacies compared to less pluripotent remedies.

    The purpose of this study was to investigate the association between body-related social comparison (BRSC) and eating disorders (EDs) by: (a) comparing the degree of BRSC in adolescents with an ED, depressive disorder (DD), and no psychiatric history; and (b) investigating whether BRSC is associated with ED symptoms after controlling for symptoms of depression and self-esteem. Participants were 75 girls, aged 12-18 (25 per diagnostic group). To assess BRSC, participants reported on a 5-point Likert scale how often they compare their body to others'. Participants also completed a diagnostic interview, Eating Disorders Inventory-2 (EDI-2), Beck Depression Inventory-II (BDI-II), and Rosenberg Self-Esteem Scale (RSE). Compared to adolescents with a DD and healthy adolescents, adolescents with an ED engaged in significantly more BRSC (p ≤ 0.001). Collapsing across groups, BRSC was significantly positively correlated with ED symptoms (p ≤ 0.01), and these associations remained even after controlling for two robust predictors of both ED symptoms and social comparison, namely BDI-II and RSE. In conclusion, BRSC seems to be strongly related to EDs. Treatment for adolescents with an ED may focus on reducing BRSC.

    Objective Medical certification is one of the basic administrative mechanisms used by social policies aimed at income protection. The assessment of work disability is central to the income protection application. Yet, there is evidence suggesting that determining work disability related to mental disorders is challenging. Although essential to the disability application process, few studies have looked at physician and other clinician experiences with the process. However, this type of information is critical to developing processes to support providers who participate in the assessments. This purpose of this paper is to explore the experiences of physicians and other clinicians assessing public long-term work disability related to mental disorders. Methods This is an exploratory and descriptive study using qualitative methods. Clinician input was gathered through focus groups and individual in-depth interviews. Verbatim transcripts were analyzed to identify recurrent and significant themes that arose during the focus groups and individual interviews. Results Many of the experiences that the clinicians in this sample discussed related to the difficulty of trying to fill the roles of advocate and medical expert as well as the challenge of determining the impact of functional capacity and work ability. The findings also highlight the current gap in knowledge about the factors that affect successful functioning in general and at work in particular. Conclusions Given the challenges created by the current state of knowledge, it may be useful to consider a category of “partial disability”. In addition, the fact that work disability depends on the interaction between the experience of the mental disorder and specific job requirements and the fact that people applying for public long-term disability are not working, it might be helpful to offer a clear description and guidelines of the meaning of work ability.

    In recent years the greatest progress in our understanding of pneumoconioses, other than those produced by asbestos, silica, and coal, has been in the arena of metal-induced parenchymal lung disorders. Inhalation of metal dusts and fumes can induce a wide range of lung pathology, including airways disorders, cancer, and parenchymal diseases. The emphasis of this update is on parenchymal diseases caused by metal inhalation, including granulomatous disease, giant cell interstitial pneumonitis, chemical pneumonitis, and interstitial fibrosis, among others. The clinical characteristics, epidemiology, and pathogenesis of disorders arising from exposure to aluminum, beryllium, cadmium, cobalt, copper, iron, mercury, and nickel are presented in detail. Metal fume fever, an inhalation fever syndrome attributed to exposure to a number of metals, is also discussed. Advances in our knowledge of antigen-specific immunologic reactions in the lung are particularly evident in disorders secondary to beryllium and nickel exposure, where immunologic mechanisms have been well characterized. For example, current evidence suggests that beryllium acts as an antigen, or hapten, and is presented by antigen-presenting cells to CD4+ T cells, which possess specific surface antigen receptors. Other metals such as cadmium and mercury induce nonspecific damage, probably by initiating production of reactive oxygen species. Additionally, genetic susceptibility markers associated with increased risk have been identified in some metal-related diseases such as chronic beryllium disease and hard metal disease. Future research needs include development of biologic markers of metal-induced immunologic disease, detailed characterization of human exposure, examination of gene alleles that might confer risk, and association of exposure data with that of genetic susceptibility.

    A pattern of disordered eating involving a pathological fixation with healthy food consumption, labeled orthorexia nervosa (ON), has recently generated attention; however, research has not yet investigated perceptions of ON-related behaviors. This study examined potential stigmatization of ON, compared with DSM-5 ED diagnoses. Participants (N = 505) were randomly assigned to read a vignette depicting a woman with anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), or ON. They then answered questions about the individual depicted in the vignette. A series of MANOVAs investigated whether opinions and beliefs about the person depicted varied as a function of the disorder described in the vignette. Individuals with ON were perceived as less likely to "improve with treatment" than individuals with BN, and less likely to "pull themselves together," than individuals with BED. Individuals with ON and AN were viewed as "hard[er] to talk to" and more of a "danger to others" compared with individuals with BED. ON was viewed as less distressing, less likely to evoke sympathy, and more acceptable than the other disorders. Finally, "poor living choices" were perceived as contributing more substantially to ON. Participants' attributions of various personality characteristics did not differ based on ED diagnosis. Results suggest that ON is viewed as less severe, more desirable, and more often the result of personal life choices. However, findings also imply that ON is associated with stigma, similar to DSM-5 EDs. These negative attitudes might reinforce ON behaviors, and limit awareness of their potential complications. © 2017 Wiley Periodicals, Inc.

    RNA oxidation and its biological effects are less well studied compared to DNA oxidation. However, RNA may be more susceptible to oxidative insults than DNA, for RNA is largely single-stranded and its bases are not protected by hydrogen bonding and less protected by specific proteins. Also, cellular RNA locates in the vicinity of mitochondria, the primary source of reactive oxygen species. Oxidative modification can occur not only in protein-coding RNAs, but also in non-coding RNAs that have been recently revealed to contribute towards the complexity of the mammalian brain. Damage to coding and non-coding RNAs will cause errors in proteins and disturbances in the regulation of gene expression. While less lethal than mutations in the genome and not inheritable, such sublethal damage to cells might be associated with underlying mechanisms of degeneration, especially age-associated neurodegeneration that is commonly found in the elderly population. Indeed, oxidative RNA damage has been described recently in most of the common neurodegenerative disorders including Alzheimer disease, Parkinson disease, dementia with Lewy bodies and amyotrophic lateral sclerosis. Of particular interest, the accumulating evidence obtained from studies on either human samples or experimental models coincidentally suggests that oxidative RNA damage is a feature in vulnerable neurons at early-stage of these neurodegenerative disorders, indicating that RNA oxidation actively contributes to the onset or the development of the disorders. Further investigations aimed at understanding of the processing mechanisms related to oxidative RNA damage and its consequences may provide significant insights into the pathogenesis of neurodegenerative disorders and lead to better therapeutic strategies.

    The objective of this review was to examine the evidentiary basis for binge eating disorder (BED) with reference to the Diagnostic and Statistical Manual of Mental Disorders – Fifth Edition (DSM-5) diagnostic criteria for BED. A PubMed search restricted to titles and abstracts of English-language reviews, meta-analyses, clinical trials, randomized controlled trials, journal articles, and letters using human participants was conducted on August 7, 2015, using keywords that included “binge eating disorder,” DSM-5, DSM-IV, guilt, shame, embarrassment, quantity, psychological, behavior, and “shape and weight concerns.” Of the 257 retrieved publications, 60 publications were considered relevant to discussions related to DSM-5 diagnostic criteria and were included in the current review, and 20 additional references were also included on the basis of the authors’ knowledge and/or on a review of the reference lists from relevant articles obtained through the literature search. Evidence supports the duration/frequency criterion for BED and the primary importance of loss of control and marked distress in identifying individuals with BED. Although overvaluation of shape/weight is not a diagnostic criterion, its relationship to the severity of BED psychopathology may identify a unique subset of individuals with BED. Additionally, individuals with BED often exhibit a clinical profile consisting of psychiatric (eg, mood, obsessive–compulsive, and impulsive disorders) and medical (eg, gastrointestinal symptoms, metabolic syndrome, and type 2 diabetes) comorbidities and behavioral profiles (eg, overconsumption of calories outside of a binge eating episode and emotional eating). Future revisions of the BED diagnostic criteria should consider the inclusion of BED subtypes, perhaps based on the overvaluation of shape/weight, and an evidence-based reassessment of severity criteria.

    Research among youths with obsessive compulsive disorder (OCD) has shown a significant relationship between illness severity, treatment outcome, and the family environment yet little work has been undertaken among the broader class of obsessive compulsive and related disorders (OCRDs) - Trichotillomania, body dysmorphic disorder (BDD), skin picking disorder (SPD), and hoarding. The aim of this study was to (1) review the family functioning literature among paediatric OCRDs, (2) address limitations to previous studies, and (3) highlight areas in need of further research. A review of the literature was conducted using several databases (i.e., Google Scholar, PubMed, ScienceDirect) and employing key search terms (e.g., 'family functioning', 'paediatric OCD'). The resultant articles examined several domains subsumed under the broader heading of family environment including parental mental health, parenting practices, family dynamics, family involvement with symptoms, and family emotional climate. The literature reviewed demonstrated a strong relationship between paediatric OCD and adverse family functioning (e.g., parental symptoms of anxiety and depression, family accommodation, family strain and stress, parental guilt and fear) in all identified domains. While family functioning research in paediatric HPD was relatively scant, research suggested similar familial dysfunction (e.g., limited independence, low family cohesion, family violence). Collectively, only 1 article, examining BDD, assessed family functioning within other OCRDs. This review supports the need for further research in the OCRDs. Limitations to the available literature and targeted suggestions for future research are discussed. The domains of family environment in this study indicate specific family functioning deficits that may serve as aetiological and/or maintenance factors in paediatric OCRDs, possibly contributing to the understanding of these complex disorders. The recognition of family deficits

    Sleep-related breathing disorders encompass a range of disorders in which abnormal ventilation occurs during sleep as a result of partial or complete obstruction of the upper airway, altered respiratory drive, abnormal chest wall movement, or respiratory muscle function. The most common of these is obstructive sleep apnea (OSA), occurring in both adults and children, and causing significant cognitive and daytime dysfunction and reduced quality of life. OSA patients experience repetitive brief cessation of breathing throughout the night, which causes intermittent hypoxemia (reductions in hemoglobin oxygen levels) and fragmented sleep patterns. These nocturnal events result in excessive daytime sleepiness, and changes in mood and cognition. Chronic excessive sleepiness during the day is a common symptom of sleep-related breathing disorders, which is assessed in sleep clinics both subjectively (questionnaire) and objectively (sleep latency tests). Mood changes are often reported by patients, including irritability, fatigue, depression, and anxiety. A wide range of cognitive deficits have been identified in untreated OSA patients, from attentional and vigilance, to memory and executive functions, and more complex tasks such as simulated driving. These changes are reflected in patient reports of difficulty in concentrating, increased forgetfulness, an inability to make decisions, and falling asleep at the wheel of a motor vehicle. These cognitive changes can also have significant downstream effects on daily functioning. Moderate to severe cases of the disorder are at a higher risk of having a motor vehicle accident, and may also have difficulties at work or school. A number of comorbidities may also influence the cognitive changes in OSA patients, including hypertension, diabetes, and stroke. These diseases can cause changes to neural vasculature and result in neural damage, leading to cognitive impairments. Examination of OSA patients using neuroimaging techniques such

  1. Allergic contact dermatitis.

    Allergic contact dermatitis is a frequent inflammatory skin disease. The suspected diagnosis is based on clinical symptoms, a plausible contact to allergens and a suitable history of dermatitis. Differential diagnoses should be considered only after careful exclusion of any causal contact sensitization. Hence, careful diagnosis by patch testing is of great importance. Modifications of the standardized test procedure are the strip patch test and the repeated open application test. The interpretation of the SLS (sodium lauryl sulfate) patch test as well as testing with the patients' own products and working materials are potential sources of error. Accurate patch test reading is affected in particular by the experience and individual factors of the examiner. Therefore, a high degree of standardization and continuous quality control is necessary and may be supported by use of an online patch test reading course made available by the German Contact Dermatitis Research Group. A critical relevance assessment of allergic patch test reactions helps to avoid relapses and the consideration of differential diagnoses. Any allergic test reaction should be documented in an allergy ID card including the INCI name, if appropriate. The diagnostics of allergic contact dermatitis is endangered by a seriously reduced financing of patch testing by the German statutory health insurances. Restrictive regulations by the German Drug Law block the approval of new contact allergens for routine patch testing. Beside the consistent avoidance of allergen contact, temporary use of systemic and topical corticosteroids is the therapy of first choice.

  2. Allergic conjunctivitis in Asia.

    Thong, Bernard Yu-Hor

    2017-04-01

    Allergic conjunctivitis (AC), which may be acute or chronic, is associated with rhinitis in 30%-70% of affected individuals, hence the term allergic rhinoconjunctivitis (AR/C). Seasonal and perennial AC is generally milder than the more chronic and persistent atopic and vernal keratoconjunctivitis. Natural allergens like house dust mites (HDM), temperate and subtropical grass and tree pollen are important triggers that drive allergic inflammation in AC in the Asia-Pacific region. Climate change, environmental tobacco smoke, pollutants derived from fuel combustion, Asian dust storms originating from central/north Asia and phthalates may also exacerbate AR/C. The Allergies in Asia Pacific study and International Study of Asthma and Allergies in Childhood provide epidemiological data on regional differences in AR/C within the region. AC significantly impacts the quality of life of both children and adults, and these can be measured by validated quality of life questionnaires on AR/C. Management guidelines for AC involve a stepped approach depending on the severity of disease, similar to that for allergic rhinitis and asthma. Topical calcineurin inhibitors are effective in certain types of persistent AC, and sublingual immunotherapy is emerging as an effective treatment option in AR/C to grass pollen and HDM. Translational research predominantly from Japan and Korea involving animal models are important for the potential development of targeted pharmacotherapies for AC.

    1996-11-01

    Conventional approaches to the analysis of sleep and sleep apnea do not describe all of the critical events that result from upper airway narrowing during sleep. The hypersomnolence that drives treatment is mainly due to microarousals, but these are poorly documented with conventional epoch-based sleep staging. The counting of apneas and hypopneas also fails to document other equally important events, such as the arousals due to increased respiratory effort in response to partial upper airway narrowing that may not cause significant hypopnea, hypoxemia, or even snoring. Modifications of conventional polysomnography, such as microarousal detection and analysis of the ribcage/abdominal paradox, may be an improvement. However, no system has been shown to be better than any other at identifying the critical events that produce symptoms of sleep-related breathing disorders, and thus be likely to respond to effective treatment. The time is right to explore innovative ways to characterize sleep-related breathing disorders, such as those derived from the cardiovascular change related to upper airway obstruction and arousal, without the shackles of conventional polysomnography. New monitoring techniques need to identify patients with events that will respond to treatment, not mimic the flawed gold standard of polysomnography.

    2011-02-01

    Temporomandibular disorder (TMD) is a collective term used to identify a group of musculoskeletal conditions of the temporomandibular region. Bruxism is a non-functional activity characterized by repeated tooth clenching or grinding in an unconscious manner. Over the time bruxism may lead to TMD by the uploading it causes. Nasal obstruction is a common complaint that necessitates mouth breathing when severe. The treatment of bruxism is frequently performed by oral appliances, which induce occlusal disengagement and relax jaw musculature and therefore reduce the force on the temporomandibular joint (TMJ). We believe that nasal obstruction may indirectly have a preemptive and therapeutic effect on sleep bruxism related TMD by causing mouth breathing.

    1991-09-01

    The symptoms of posttraumatic stress disorder (PTSD) suggest sympathetic nervous system hyperarousal and hyperreactivity. Pathophysiology of this condition may include stress-activated limbic kindling. Antikindling agents lithium and carbamazepine have been found effective for PTSD symptoms of intrusive reexperiencing and increased arousal. These facts suggest that valproate, another drug shown to interfere with limbic kindling, could also be effective for treatment of PTSD. An open clinical trial of valproate was conducted in 16 Vietnam veterans diagnosed with DSM-III-R combat-related PTSD. Ten of 16 patients showed significant improvement, especially in hyperarousal/hyperreactivity symptoms. The efficacy of valproate in the treatment of PTSD should be rigorously studied.

Recently, progress has been made using different next-generation sequencing approaches in combination with new functional readout systems. This approach has provided novel insights into the biological pathways underlying ID, improved the diagnostic process and offered new targets for therapy. In this Review, we highlight the insights obtained from recent studies on the role of genetics in ID and its impact on diagnosis, prognosis and therapy. We also discuss the future directions of genetics research for ID and related neurodevelopmental disorders.

    The prevalence of asthma and allergic diseases is rising worldwide. Evidence on potential causal pathways of asthma and allergies is growing, but findings have been contradictory, particularly on the interplay between allergic diseases and understudied social determinants of health like migration status. This review aimed at providing evidence for the association between migration status and asthma and allergies, and to explore the mechanisms between migration status and the development of asthma and allergies. Systematic review on asthma and allergies and immigration status in accordance with the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The pooled odds ratio (OR) of the prevalence of asthma in immigrants compared to the host population was 0.60 (95% CI 0.45-0.84), and the pooled OR for allergies was 1.01 (95% CI 0.62-1.69). The pooled OR for the prevalence of asthma in first generation versus second generation immigrants was 0.37 (95% CI 0.25-0.58). Comparisons between populations in their countries of origin and those that emigrated vary depending on their level of development; more developed countries show higher rates of asthma and allergies. Our findings suggest a strong influence of the environment on the development of asthma and allergic diseases throughout the life course. The prevalence of asthma is generally higher in second generation than first generation immigrants. With length of residence in the host country the prevalence of asthma and allergic diseases increases steadily. These findings are consistent across study populations, host countries, and children as well as adults. Differences have been found to be significant when tested in a linear model, as well as when comparing between early and later age of migration, and between shorter and longer time of residence.

    The risk factors for sensitisation to rice and the involved allergens are still partially unknown. In this study we evaluated the clinically relevant aspects of rice allergy in DBPCF-positive patients, the major rice allergens, the severity of peach- and rice-induced symptoms in respect to Pru p 3 sensitisation and the role of anti-rPru p 3 IgE levels as a risk factor for rice allergy. In 148 peach-allergic subjects, patients with allergic reactions to rice and rice-positive serum IgE were selected. Symptoms were verified by double-blind placebo-controlled food challenges (DBPCFCs), performed at a maximum dosage of 25 g. Rice allergens, identified by IgE immunoblotting, were characterised by N-terminal amino acid sequencing. The relationship between anti-rPru p 3, 1 and 4 IgE levels and rice symptoms were statistically analysed. Eight out of 10 recruited rice-allergic patients had positive DBPCFCs, while 2 patients were not challenged due to their previously documented severe reactions. All patients with rice-induced symptoms were Pru p 3 positive and presented with higher anti-rPru p 3 levels than the rice-sensitised but tolerant patients. A 9-kDa lipid transfer protein, which was highly homologous to Pru p 3, was identified as the major rice allergen and elicited a positive response in all of the patients. Five patients reacted to a putative 15- to 17-kDa rice allergenic protein, and 3 patients reacted to an [alpha]-amylase/subtilisin inhibitor that was approximately 20 kDa. Rarely, allergic reactions to rice can arise in patients with peach allergies who are sensitised to Pru p 3, particularly in patients with high anti-rPru p 3 IgE levels. Copyright © 2013 S.

    Wound closure with 2-octyl cyanoacrylate (Dermabond; Ethicon, Somerville, New Jersey USA) has recently increased in popularity across a wide spectrum of physicians ranging from surgeons to emergency medicine practitioners. Generally, very few complications are associated with Dermabond and are usually related to application techniques. Uncommonly, patients present with allergic reactions to the adhesive compounds; these allergies are often misdiagnosed as cellulitis or another infectious process, and are incorrectly treated. This report describes a rare case of a diffuse cutaneous allergic reaction to Dermabond following its use to close a surgical incision, its prompt identification, and treatment after presentation to an emergency department.

  13. TONSILLECTOMY IN THE ALLERGIC CHILD

    Edema is the chief factor in enlargement of tonsils of children with allergic disease. In the absence of infection tonsillectomy and adenoidectomy are contraindicated in the allergic child except when obstruction is present. Infection produces one of two distinct patterns when it influences allergic states, the pattern depending upon the nature of the infectious disease. Chronic infection of the upper respiratory tract in the allergic child produces a pattern simulating that of acute respiratory infection. If, in the presence of infected tonsils and adenoids, management of the allergic state does not produce results, tonsillectomy and adenoidectomy are indicated. Management of the allergic disease must be continued postoperatively. Whether infection is present or absent, allergic disease can be controlled only through competent management of it.

    This review serves as a systematic guide to the genetics of generalized anxiety disorder (GAD) and further focuses on anxiety-relevant endophenotypes, such as pathological worry fear of uncertainty, and neuroticism. We inspect clinical genetic evidence for the familialityl heritability of GAD and cross-disorder phenotypes based on family and twin studies. Recent advances of linkage studies, genome-wide association studies, and candidate gene studies (eg, 5-HTT, 5-HT1A, MAOA, BDNF) are outlined. Functional and structural neuroimaging and neurophysiological readouts relating to peripheral stress markers and psychophysiology are further integrated, building a multilevel disease framework. We explore etiologic factors in gene-environment interaction approaches investigating childhood trauma, environmental adversity, and stressful life events in relation to selected candidate genes (5-HTT, NPSR1, COMT, MAOA, CRHR1, RGS2), Additionally, the pharmacogenetics of selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor treatment are summarized (5-HTT, 5-HT2A, COMT, CRHR1). Finally, GAD and trait anxiety research challenges and perspectives in the field of genetics, including epigenetics, are discussed. PMID:28867940

    The scientific understanding of the neurobiological priniciples of alcoholism has made significant progress in recent years. Especially the effects of ethanol on the neurotransmitter-systems are well studied. Dopaminergic and GABAergic facilitation contribute to the stimulating effects of low doses of alcohol while many of its adverse effects are mediated by glutamatergic inhibition at higher doses. A reduced serotonine-metabolism was shown to be a risk factor for the development of an alcohol dependence. The historic success of absinthe is discussed in this context. Absinthe is a mixture of ethanol and thujone, a substance that leads to a GABAergic inhibition as well as a reduced serotonergic responsiveness. Many studies substantiate the role of cannabinoid as well as striatal opiate-receptors in alcohol-related disorders. Neuroimaging studies could prove the important role of the reward system in this connection. Genetic factors were shown to be predisposing, however biological and environmental factors have a regulatory effect on the gene expression. Disturbances of the hpa-axis (hypothalamus-pituitary gland-adrenal cortex) were also shown to play a role in alcohol dependence. The understanding of these neurobiological principles of alcohol-related disorders should contribute to enhance and improve their therapeutic options.

    Joubert syndrome (JS) is a rare autosomal recessive (AR), neurological condition characterized by dysgenesis of the cerebellar vermis with the radiological hallmark of molar tooth sign, oculomotor apraxia, recurrent hyperventilation and intellectual disability. Most cases display a broad spectrum of additional features, including polydactyly, retinal dystrophy and renal abnormalities, which define different subtypes of JS-related disorders (JSRDs). To date, 23 genes have been shown to cause JSRDs, and although most of the identified genes encode proteins involved in cilia function or assembly, the molecular mechanisms associated with ciliary signaling remain enigmatic. Arab populations are ethnically diverse with high levels of consanguinity (20–60%) and a high prevalence of AR disorders. In addition, isolated communities with very-high levels of inbreeding and founder mutations are common. In this article, we review the 70 families reported thus far with JS and JSRDs that have been studied at the molecular level from all the Arabic countries and compile the mutations found. We show that JS and the related JSRDs are genetically heterogeneous in Arabs, with 53 mutations in 15 genes. Thirteen of these mutations are potentially founder mutations for the region.

    In general work involves health promoting functions but can also have hazardous impacts on well-being. Due to a massive change in working conditions it has become increasingly more recognized that depressive disorders are highly prevalent at the workplace and that work stress belongs to the most common triggers of depressive disorders, particularly in men. It is relevant to differentiate between subjectively experienced burnout and clinical depression. The best investigated psychosocial work stressors include increased job demands in connection with low control possibilities and lack of gratification, interpersonal conflicts, role stress and social isolation. For the treatment of work-related clinical depression, an additional focus of interpersonal psychotherapy (IPT) of depression, namely "work-related stress and burnout experience" was conceptualized based on a vulnerability-stress model and the fact that work usually takes place in an interpersonal context. This new problem area focuses on role stress and conflicts at work and the reduction of stressful working conditions. Interpersonal psychotherapy has so far been useful for the treatment of depression due to problems at work; however, further studies are needed to evaluate the efficacy of this newly designed problem area.

    Background and aims The main aim of this study was to analyze and describe the clinical characteristics and shared personality traits in different impulsivity-compulsivity spectrum disorders: substance use disorders (SUD), gambling disorder (GD), and bulimia nervosa (BN). The specific aims were to compare personality differences among individuals with pure SUD, BN with and without SUD, and GD with and without SUD. In addition, we assessed the differential predictive capacity of clinical and personality variables in relation to diagnostic subtype. Methods The sample comprised 998 subjects diagnosed according to DSM-IV-TR criteria: 101 patients were diagnosed with SUD, 482 with GD, 359 with BN, 11 with GD + SUD, and 45 patients with BN + SUD. Various assessment instruments were administered, as well as other clinical measures, to evaluate their predictive capacity. Results Marked differences in personality traits were observed between groups. Novelty seeking, harm avoidance, self-directedness, cooperation, and self-transcendence best differentiated the groups. Notably, novelty seeking was significantly higher in the two dual pathology subgroups. Patients with dual pathology showed the most dysfunctional personality profiles. Discussion and conclusion Our results indicate the existence of shared dysfunctional personality traits among the groups studied, especially in novelty seeking and self-directedness.

    Allergic diseases have an increasing worldwide prevalence and a great impact on the health related costs. The research is focused on the study of etiological and risk factors of allergic diseases that can potentially be modified with primary, secondary and tertiary prevention strategies. Many of these measures do not have a definitively proven effect taking place in a controlled context different to what happens in real life. This paper aims to review the latest evidence on prevention of allergic diseases considering certainties and unresolved issues and focuses mainly on environmental, dietary, pharmacological and immunological preventive strategies for different levels of prevention. It is imperative to have a better understanding of genetic and environmental factors that cause allergic diseases to optimize preventive measures that are effective in reversing the increasing trend in the prevalence of allergic illnesses in childhood.

    Research in the area of prevention of allergic disorders through modification of the intestinal microbiota by provision of probiotics and/or prebiotics is relatively new. This paper briefly summarizes evidence regarding the role of probiotics and/or prebiotics in reducing the risk of allergy. There are studies that show a protective effect, no effect or even a predisposing effect of using probiotics and/or prebiotics in preventing allergic disease. A variety of methodological issues are likely to contribute to current uncertainty. These include differences in the study population (high-risk vs unselected population), optimal strain selection (all probiotics are not equal), differences in definitions of outcomes, timing and duration of the interventions, and a lack of repeat studies.

    To present five patients with zolpidem-induced sleep-related behavioural disorders. Evaluation using a questionnaire designed to study sleep behaviours and past medical history in all patients. The patients performed complex actions while sleep-walking (telephoning, house-cleaning, feeding the dog or waxing their legs). Inappropriate feeding behaviour with excessive food intake during the night were reported by all patients. All had weight gain, which in one patient led to extreme obesity. Two patients suffered injuries (knife cuts and burns) related to attempting to prepare food. One patient took a laxative. Withdrawal of zolpidem resolved the behaviours in all cases, highlighting the importance of an adequate diagnosis of this side effect.

    It is well established that individuals with bipolar disorder are differentially affected by substance-related as well as medical disorders (ie, cardiometabolic disorders, respiratory disorders, neurological disorders, and infectious diseases). Emerging evidence indicates that some comorbid conditions (eg, diabetes mellitus) in bipolar individuals may be subserved by overlapping neurobiological networks. Disturbances in glucocorticoid/insulin signaling and immunoinflammatory effector systems are points of pathophysiological commonality between bipolar disorder and “stress-sensitive” medical disorders. Subphenotyping bipolar disorder as a function of comorbidity and temporality of onset may provide an opportunity for refining disease pathophysiological models and developing innovative disease-modifying therapies.

    It has been proposed that social anxiety disorder (SAD) is associated with automatic information processing biases resulting in hypersensitivity to signals of social threat such as negative facial expressions. However, the nature and extent of automatic processes in SAD on the behavioral and neural level is not entirely clear yet. The present review summarizes neuroscientific findings on automatic processing of facial threat but also other disorder-related stimuli such as emotional prosody or negative words in SAD. We review initial evidence for automatic activation of the amygdala, insula, and sensory cortices as well as for automatic early electrophysiological components. However, findings vary depending on tasks, stimuli, and neuroscientific methods. Only few studies set out to examine automatic neural processes directly and systematic attempts are as yet lacking. We suggest that future studies should: (1) use different stimulus modalities, (2) examine different emotional expressions, (3) compare findings in SAD with other anxiety disorders, (4) use more sophisticated experimental designs to investigate features of automaticity systematically, and (5) combine different neuroscientific methods (such as functional neuroimaging and electrophysiology). Finally, the understanding of neural automatic processes could also provide hints for therapeutic approaches. PMID:23745116

    Work-related post-traumatic stress disorder (PTSD) is an important condition encountered by many occupational health practitioners. To carry out an in-depth review of the research on occupational groups that are at particular risk of developing work-related PTSD. A literature search was conducted in the databases OVID MEDLINE, OVID Embase, Ovid PsycINFO, ISI Web of Science and CSA Health and Safety Science Abstracts. Professionals such as police officers, firefighters and ambulance personnel often experience incidents that satisfy the stressor criterion for the PTSD diagnosis. Other professional groups such as health care professionals, train drivers, divers, journalists, sailors and employees in bank, post offices or in stores may also be subjected to work-related traumatic events. Work-related PTSD usually diminishes with time. Mental health problems prior to the traumatic event and weak social support increase the risk of PTSD. Prevention of work-related PTSD includes a sound organizational and psychosocial work environment, systematic training of employees, social support from colleagues and managers and a proper follow-up of employees after a critical event.

    Vitamin E is found in eight forms in nature which include four tocopherols (alpha, beta, gamma and delta) and four tocotrianols (alpha, beta, gamma and delta). The classic effect of vitamin E is to reduce and prevent oxygen damage to the tissue and is useful for the treatment of pain, inflammation and allergic reactions. In addition to antioxidant activity, vitamin E also has a number of different and related functions. It protects against cancer, improves immune response, lowers the incidence of infectious diseases, cardiovascular diseases and is protective in allergy and asthma risk, and other disorders. Vitamin E increases n-6 polyunsaturated fatty acid (PUFA) and decreases n-3 PUFA, an effect that diminishes asthma and allergic diseases. Moreover, vitamin E regulates vascular cell adhesion molecule-1 (VCAM-1)-dependent leukocyte migration through its oxidant and non-antioxidant effect. Furthermore, vitamin E modulates the endothelial function by altering VCAM-1-induced oxidative activation of endothelial cell PKCα. However, vitamin E is not consistently associated with asthma and/or allergy, and in some cases there are conflicting results on allergy and inflammatory diseases. The association of vitamin E and allergy appears to be very complex, and further study needs to clarify this dilemma.

    2013-01-01

    Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual behavior, and eating, are a serious and increasingly recognized complication of dopamine replacement therapy in Parkinson's disease (PD). Other impulsive-compulsive behaviors have been linked to dopaminergic medications; these include punding (stereotyped, repetitive, purposeless behaviors) and dopamine dysregulation syndrome (DDS; compulsive medication overuse). ICDs have been most closely related to the use of dopamine agonists (DAs), particularly at higher dosages; in contrast, DDS is primarily associated with shorter-acting, higher-potency dopaminergic medications, such as apomorphine and levodopa. Risk factors for ICDs may include male sex; younger age; younger age at PD onset; a pre-PD history of ICD(s); personal or family history of substance abuse; bipolar disorder; gambling problems; and impulsive personality traits. The primary treatment of ICDs in PD is discontinuation of DA therapy. Not all patients can tolerate this, however, due to worsening motor symptoms and/or DA withdrawal syndrome (a severe, stereotyped drug withdrawal syndrome similar to that of other psychostimulants). While psychiatric medications are frequently used to treat ICDs in the general population, there is no empirical evidence to suggest that they are effective in PD. Given the paucity of treatment options and potentially serious consequences of ICDs in PD, it is critical for patients to be monitored closely for their development. As empirically validated treatments for ICDs emerge, it will also be important to examine their efficacy and tolerability in individuals with comorbid PD. Copyright © 2012 S. Karger AG, Basel.

    Pseudohypoparathyroidism type 1a (PHP1a) is characterized by hypocalcaemia and hyperphosphatemia due to parathyroid hormone resistance, in association with the features of Albright's hereditary osteodystrophy (AHO). PHP1a is caused by maternally inherited inactivating mutations of Gs-alpha, which is encoded by a complex imprinted locus termed GNAS. Paternally inherited mutations can lead either to pseudopseudohypoparathyroidism (PPHP) characterized by AHO alone, or to progressive osseous heteroplasia (POH), characterized by severe heterotopic ossification. The clinical aspects and molecular genetics of PHP1a and its related disorders are reviewed together with the 343 kindreds with Gs-alpha germline mutations reported so far in the literature. These 343 (176 different) mutations are scattered throughout the 13 exons that encode Gs-alpha and consist of 44.9% frameshift, 28.0% missense, 14.0% nonsense, and 9.0% splice-site mutations, 3.2% in-frame deletions or insertions, and 0.9% whole or partial gene deletions. Frameshift and other highly disruptive mutations were more frequent in the reported 37 POH kindreds than in PHP1a/PPHP kindreds (97.3% vs. 68.7%, P < 0.0001). This mutation update and respective genotype–phenotype data may be of use for diagnostic and research purposes and contribute to a better understanding of these complex disorders. PMID:25219572

    Cannabis is the most widely used illicit psychoactive substance world-wide, yet no medication is approved for the treatment of intoxication, withdrawal, or cannabis use disorder (CUD). To comprehensively review the current state of knowledge. Search of the PubMed electronic data base and review of reference lists of relevant articles to identify controlled clinical trials of pharmacological treatment. The search identified 4 trials for specific intoxication symptoms (none for global intoxication), 7 trials for withdrawal, and 12 phase II trials for CUD. One or two trials each suggest that propranolol is effective for some intoxication symptoms, antipsychotics for cannabis-induced psychosis, and dronabinol (synthetic THC) and gabapentin for cannabis withdrawal. Of 10 medications and one medication combination studied in 12 trials for CUD, only two medications were effective (in single trials): gabapentin and Nacetylcysteine (in adolescents). Not effective were dronabinol and several antidepressants, anticonvulsants, and antianxiety medications. Three trials of antidepressants for CUD with comorbid depression gave inconsistent results. A trial of atomoxetine for CUD with comorbid ADHD showed no efficacy. Five trials of second-generation antipsychotics for CUD with comorbid schizophrenia showed none better than any other. Further research is needed to confirm the efficacy of gabapentin for withdrawal and gabapentin and N-acetylcysteine for CUD and to develop new medications for all 3 cannabis-related disorders.

    Work-related musculoskeletal disorder (WMSD) prevention measures have been studied in great depth throughout various industries. While the nature and causes of these disorders have been characterized in many industries, WMSDs occurring in the U.S. mining sector have not been characterized for several years. In this report, MSHA accident/injury/illness data from 2009 to 2013 were characterized to determine the most frequently reported WMSDs in the U.S. mining sector. WMSDs were most frequently reported in workers with less than 5 years or more than 20 years of mining experience. The number of days lost from work was the highest for shoulder and knee injuries and was found to increase with worker age. Underground and surface coal, surface stone and stone processing plants experienced the greatest number of WMSDs over the period studied. WMSDs were most commonly caused by an employee suffering from an overexertion, falls or being struck by an object while performing materials handling, maintenance and repair tasks, getting on or off equipment or machines, and walking or running. The injury trends presented should be used to help determine the focus of future WMSD prevention research in mining. PMID:27294012

    2014-01-01

    Chronic infection with hepatitis C virus (HCV) is associated with a large spectrum of extrahepatic manifestations (EHMs), mostly immunologic/rheumatologic in nature owing to B-cell proliferation and clonal expansion. Neurological complications are thought to be immune-mediated or secondary to invasion of neural tissues by HCV, as postulated in transverse myelitis and encephalopathic forms. Primarily axonal neuropathies, including sensorimotor polyneuropathy, large or small fiber sensory neuropathy, motor polyneuropathy, mononeuritis, mononeuritis multiplex, or overlapping syndrome, represent the most common neurological complications of chronic HCV infection. In addition, a number of peripheral demyelinating disorders are encountered, such as chronic inflammatory demyelinating polyneuropathy, the Lewis-Sumner syndrome, and cryoglobulin-associated polyneuropathy with demyelinating features. The spectrum of demyelinating forms also includes rare cases of iatrogenic central and peripheral nervous system disorders, occurring during treatment with pegylated interferon. Herein, we review HCV-related demyelinating conditions, and disclose the novel observation on the significantly increased frequency of chronic demyelinating neuropathy with anti-myelin-associated glycoprotein antibodies in a cohort of 59 consecutive patients recruited at our institution. We also report a second case of neuromyelitis optica with serum IgG autoantibody against the water channel aquaporin-4. The prompt recognition of these atypical and underestimated complications of HCV infection is of crucial importance in deciding which treatment option a patient should be offered.

    Introduction It is well established that individuals exposed to alcohol in utero have reduced cortical grey matter volumes. However, the candidate determinants of these reductions, cortical thickness (CT) and surface area (SA), have not been investigated exclusively in alcohol-related neurodevelopmental disorder (ARND), the most prevalent fetal alcohol spectrum disorder subgroup that lacks the characteristic facial dysmorphology. Methods T1-weighted magnetic resonance imaging scans were obtained from 88 participants (8–16 years), 36 diagnosed with ARND and 52 typically developing controls. Scans were submitted to the CIVET pipeline (version 1.1.10). Deformable models were used to construct the inner white matter surfaces and pial surfaces from which CT and SA measures were derived. Group differences in cortical volume, CT, and SA were computed using a general linear model covaried for age, sex, and handedness. Results Global cortical volume reductions in ARND did not reflect CT, which did not differ between groups. Instead, volume decreases were consistent with global SA reductions in bilateral frontal and temporal as well as right occipital regions. Local reductions in SA were observed in the right superior temporal gyrus and the right occipital-temporal region. Conclusion Results suggest that in ARND, prenatal alcohol exposure perturbs global SA to a greater degree than CT, particularly in the right temporal lobe. PMID:24653953

    Castleman's disease is a rare primary disease of the lymph nodes. Little is known about the management of the disease. Surgical treatment gives a very good result. What other modalities of treatment could be done is not yet established. The role of surgery gives good result and follow up evaluation is satisfactory. We found a solitary intra-abdominal mass of lymphoid hyperplasia with a histological diagnosis of Castlemans disease identified in the pathological data base. Unicentric disease was defined as it was a solitary mass. Clinical, Radiological and Laboratory data were analysed to evaluate treatment response. The patient also has related disorders as Acanthosis nigricans, Myoneuronal disorder as-MG and bronchiolitis. The patient diagnosed as angiofollicular hyperplasia (Castleman's disease). After evaluation patient under went surgical treatment, partial excision of tumor mass due to morbid adhesion with inferior vena cava. The patient becomes symptom free and lump disappears within 60 days of treatment. There was no recurrence of the disease after further evaluation. The author recommends that in Unicentric variant of Castlemans disease surgical resection of the tumor is curative. The unicentric tumour may be hyaline-vascular or hyaline-vascular/ plasma cell type. Partial resection, Radiotherapy or observation alone may avoid excessive aggressive therapy.

In addition, a number of peripheral demyelinating disorders are encountered, such as chronic inflammatory demyelinating polyneuropathy, the Lewis-Sumner syndrome, and cryoglobulin-associated polyneuropathy with demyelinating features. The spectrum of demyelinating forms also includes rare cases of iatrogenic central and peripheral nervous system disorders, occurring during treatment with pegylated interferon. Herein, we review HCV-related demyelinating conditions, and disclose the novel observation on the significantly increased frequency of chronic demyelinating neuropathy with anti-myelin-associated glycoprotein antibodies in a cohort of 59 consecutive patients recruited at our institution. We also report a second case of neuromyelitis optica with serum IgG autoantibody against the water channel aquaporin-4. The prompt recognition of these atypical and underestimated complications of HCV infection is of crucial importance in deciding which treatment option a patient should be offered. PMID:25198705

    Allergic disorders commonly involve both chronic tissue inflammation and remodeling caused by immunological reactions to various antigens on tissue surfaces. Due to their anatomical location, vascular endothelial cells are the final responders to interact with various exogenous factors that come into contact with the epithelial surface, such as pathogen-associated molecular patterns (PAMPs) and antigens. Recent studies have shed light on the important roles of endothelial cells in the development and exacerbation of allergic disorders. For instance, endothelial cells have the greatest potential to produce several key molecules that are deeply involved in allergic inflammation, such as periostin and thymus and activation-regulated chemokine (TARC/CCL17). Additionally, endothelial cells were recently shown to be important functional targets for IL-33--an essential regulator of allergic inflammation. Notably, almost all endothelial cell responses and functions involved in allergic inflammation are not suppressed by corticosteroids. These corticosteroid-refractory endothelial cell responses and functions include TNF-α-associated angiogenesis, leukocyte adhesion, IL-33-mediated responses and periostin and TARC production. Therefore, these unique responses and functions of endothelial cells may be critically involved in the pathogenesis of various allergic disorders, especially their refractory processes. Here, we review recent studies, including ours, which have elucidated previously unknown pathophysiological roles of vascular endothelial cells in allergic inflammation and discuss the possibility of endothelium-targeted therapy for allergic disorders.

    This study has investigated the prevalence of work-related musculoskeletal disorders (WMSDs), the most commonly affected body parts, the risk factors of WMSDs and the coping strategies adopted by hairdressers. The study design was a cross-sectional descriptive survey design. Two hundred and ninety-nine hairdressers (242 females and 57 males) from salons in Surulere and Mushin Local Government Areas of Lagos State completed a 27-item questionnaire. They were selected using a non-probability consecutive sampling technique. The inferential analysis was conducted using the Chi2 test. The level of significance stood at p < 0.05. The 12-month prevalence of musculoskeletal disorders stood at 75.6%. Two hundred and twenty-one (91.3%) participants reported gradual onset of musculoskeletal disorders. One hundred and sixteen (47.9%) participants had the onset of the WMSDs at the age range of 26-35 years. The most commonly affected body parts included the low back (76.3%), shoulder (62.5%) and neck (46.3%). Some of the major job risk factors of the WMSDs that were identified included: working in the same position for long periods and attending to a large number of customers in 1 day. Taking sufficient rest breaks by participants was one of the coping strategies adopted by the participants. The mean number of years of working experience was 7.85±0.4 years. One hundred and twenty-four (41.5%) participants had worked for 1-5 years. The Chi2 analysis showed that the prevalence of musculoskeletal disorders were significantly associated with the age of a participant (Chi2 = 78.78, p = 0.001), years of working experience (Chi2 = 78.03, p = 0.001) and hours spent working in a standing position (Chi2 = 8.77, p = 0.01), respectively. The age of hairdressers, their years of working and the long hours they spent working in a standing position may be significant factors that contribute to the high prevalence of the WMSDs among them. The most commonly affected body parts included the low

    Brucellosis is an anthropozoonosis caused by a Gram negative bacillus of the Brucella gender. Skin manifestations have been reported in 1.5 to 11 p. 100 of the cases. Allergic vasculitis is rare. Recently a 24-year-old man was hospitalized for signs of infection. He had been treated with tetracycline. The clinical picture was suggestive of brucellosis and the Wright test was positive at 1/1,280. There were violet and purpuric papulae on the limbs, arthritis of the knee and ankle joints and renal involvement (haematuria, proteinuria). Histology revealed fibrinoid and leukocytoclastic vasculitis of the small veinules of the subpapillary plexus. Outcome was favourable with rifampicin, doxycycline and adjuvant dapsone, together with bed rest. Several types of skin manifestations have been reported in brucellosis although cases of allergic vasculitis are rare.

  1. Epidemiology of allergic rhinitis.

    2014-09-01

    Allergic rhinitis (AR) is the archetypal allergic disease otolaryngologists encounter. Epidemiologic studies inform providers of the association of rhinitis symptoms and allergy test results in the broader population. Understanding the epidemiological characteristics of AR is important for interpreting both rhinitis symptoms and allergy tests. Articles were selected based on literature review through PubMed and personal knowledge of the author. The largest and highest-quality studies were included. The search selection was not standardized. Epidemiological studies demonstrate marked variability globally in the prevalence of both rhinitis symptoms and allergy tests. Self-reported seasonal or perennial rhinitis symptoms significantly overestimate the prevalence of AR defined by a positive history and positive allergy tests. Positive allergy tests are also common in those without self-reported rhinitis symptoms. Interpreting rhinitis symptoms and allergy testing is enhanced by an understanding of the epidemiology of AR. © 2014 ARS-AAOA, LLC.

    Foot dermatitis is a widespread condition, affecting men and women of all ages. Because of the location, this condition may present as a debilitating problem to those who have it. Allergic contact dermatitis involving the feet is frequently due to shoes or socks. The allergens that cause shoe dermatitis can be found in any constituent of footwear, including rubber, adhesives, leather, dyes, metals, and medicaments. The goal of treatment is to identify and minimize contact with the offending allergen(s). The lack of product information released from shoe manufacturers and the continually changing trends in footwear present a challenge in treating this condition. The aim of this study is to review the current literature on allergic contact shoe dermatitis; clinical presentation, allergens, patch testing, and management will be discussed. PubMed and MEDLINE databases were used for the search, with a focus on literature updates from the last 15 years.

    This review examines the question of whether there should be a cluster of disorders, including the adjustment disorders (ADs), acute stress disorder (ASD), posttraumatic stress disorder (PTSD), and the dissociative disorders (DDs), in a section devoted to abnormal responses to stress and trauma in the DSM-5. Environmental risk factors, including the individual's developmental experience, would thus become a major diagnostic consideration. The relationship of these disorders to one another is examined and also their relationship to other anxiety disorders to determine whether they are better grouped with anxiety disorders or a new specific grouping of trauma and stressor-related disorders. First how stress responses have been classified since DSM-III is reviewed. The major focus is on PTSD because it has received the most attention, regarding its proper placement among the psychiatric diagnoses. It is discussed whether PTSD should be considered an anxiety disorder, a stress-induced fear circuitry disorder, an internalizing disorder, or a trauma and stressor-related disorder. Then, ASD, AD, and DD are considered from a similar perspective. Evidence is examined pro and con, and a conclsion is offered recommending inclusion of this cluster of disorders in a section entitled "Trauma and Stressor-Related Disorders." The recommendation to shift ASD and PTSD out of the anxiety disorders section reflects increased recognition of trauma as a precipitant, emphasizing common etiology over common phenomenology. Similar considerations are addressed with regard to AD and DD.

    Allergic bronchopulmonary aspergillosis (ABPA) develops as the result of a hypersensitivity reaction to fungi of the genus Aspergillus. Clinical and radiological presentation can be atypical, requiring a high degree of suspicion on the part of the physician who treats such patients. We report the cases of two patients with APBA in whom the form of presentation--with few asthma symptoms, images showing lobar atelectasia and hilar adenopathy--led to an initial suspicion of lung cancer.

    Extrinsic allergic alveolitis (also known as hypersensitivity pneumonitis) is caused by repeated inhalation of mainly organic antigens by sensitized subjects. This induces a hypersensitivity response in the distal bronchioles and alveoli and subjects may present clinically with a variety of symptoms. The aims of this review are to describe the current concepts of the immunological response, the diverse clinical presentation of this disease, the relevant investigations and management, and areas for future studies.

  7. Allergen immunotherapy and allergic rhinitis: false beliefs

    PubMed Central

    2013-01-01

    Background Over the last 100 years, several persistent misconceptions or ‘false beliefs’ have built up around allergen immunotherapy and its use in allergic rhinitis. This is perhaps because enthusiastic physicians administered complex allergen extracts to a diverse population of patients suffering from heterogeneous atopic conditions. Here, we review evidence that counters seven of these ‘false beliefs.’ Discussion 1. The symptoms of allergic rhinitis can be more heterogeneous, more severe and more troublesome in everyday life than many physicians believe. Large-scale epidemiological surveys show that the majority of allergic rhinitis patients have at least one symptom severe enough to interfere with sleep quality, productivity and/or well-being. 2. Allergen immunotherapy is not necessarily suitable for all allergic rhinitis patients (notably those with mild symptoms). Recent evidence from double-blind, placebo-controlled, randomized clinical trials suggests that the more severe the disease, the greater the treatment effect. 3. Allergen immunotherapy is often accused of lack of efficacy (relative to pharmacotherapy, for example). However, there are now many meta-analyses, systematic reviews and high-quality clinical trials that find overwhelmingly in favor of the efficacy of allergen immunotherapy (including sublingual formulations) in allergic rhinitis induced by pollen and, increasingly, other allergens. 4. Natural-exposure and challenge-chamber trials have shown that symptom relief may become apparent within months or even weeks of the initiation of allergen immunotherapy. 5. In pollen-induced allergic rhinitis, several years of subcutaneous or sublingual allergen immunotherapy are associated with sustained clinical efficacy after subsequent treatment cessation – confirming the disease-modifying nature of this therapy. 6. Most patients seeking treatment for allergic rhinitis are polysensitized, and allergen immunotherapy has proven efficacy in large

    The aim of the study is to identify factors related to comorbid oppositional defiant disorder (ODD) and anxiety disorders (ADs). A sample of 622 children was assessed longitudinally at 3 and 5 years of age. At baseline, there were 310 boys (49.8%), most participants were of Caucasian-white ethnicity (89.1%) and attended to public school (64.0%), and families' socioeconomic status was 64.3% medium-high, 14.1% medium and 20.5% medium-low. Children diagnosed with ODD and/or AD were selected: n = 103 at 3 years of age (44 ODD, 42 AD and 17 ODD + AD) and n = 106 at 5 years of age (31 ODD, 60 AD and 15 ODD + AD). High levels of the child's negative affectivity and the mother's aggressive behavior (versus AD), and high scores in the father's psychopathology measurements (versus ODD) were related to the presence of comorbid ODD + AD at 3 years of age. High scores in approach-positive anticipation, fears (only in boys, in girls the reverse effect occurred) compared to ODD and AD independently and aggressive behavior (versus AD), and low scores for smiling and laughter (versus ODD only and AD only) were predictive of comorbidity at the 5 years of age. Temperament traits may be a common factor in explaining longitudinal ODD + AD comorbidity.

    In this paper, we review the current management of allergic rhinitis and new directions for future treatment. Currently, management includes pharmacotherapy, allergen avoidance and possibly immunotherapy. The simple washing of nasal cavities using isotonic saline provides a significant improvement and is useful, particularly in children. The most effective medication in persistent rhinitis used singly is topical corticosteroid, which decreases all symptoms, including ocular ones. Antihistamines reduce nasal itch, sneeze and rhinorrhea and can be used orally or topically. When intranasal antihistamine is used together with topical corticosteroid, the combination is more effective and acts more rapidly than either drug used alone. Alternative therapies, such as homeopathy, acupuncture and intranasal carbon dioxide, or devices such nasal air filters or intranasal cellulose, have produced some positive results in small trials but are not recommended by Allergic Rhinitis and its Impact on Asthma (ARIA). In the field of allergic immunotherapy, subcutaneous and sublingual routes are currently used, the former being perhaps more efficient and the latter safer. Sublingual tablets are now available. Their efficacy compared to standard routes needs to be evaluated. Efforts have been made to develop more effective and simpler immunotherapy by modifying allergens and developing alternative routes. Standard allergen avoidance procedures used alone do not provide positive results. A comprehensive, multi-trigger, multi-component approach is needed, including avoidance of pollutants such as cigarette smoke. PMID:25374672

    This article reviews the history of allergic fungal rhinosinusitis and the clinical, pathologic, and radiographic criteria necessary to establish its diagnosis and differentiate this disease from other types of chronic rhinosinusitis. Allergic fungal rhinosinusitis is a noninvasive fungal form of sinus inflammation characterized by an often times unilateral, expansile process in which the typical allergic "peanut-butter-like" mucin contributes to the formation of nasal polyps, hyposmia/anosmia, and structural changes of the face. IgE sensitization to fungi is a necessary, but not sufficient, pathophysiologic component of the disease process that is also defined by microscopic visualization of mucin-containing fungus and characteristic radiological imaging. This article expounds on these details and others including the key clinical and scientific distinctions of this diagnosis, the pathophysiologic mechanisms beyond IgE-mediated hypersensitivity that must be at play, and areas of current and future research.

    Influenza A virus is the respiratory pathogen responsible for influenza. Infection by the 2009 pandemic influenza A (H1N1) virus caused severe lower airway inflammation and pneumonia. Asthma is a chronic inflammatory disorder of the airways that affects the entire brachial tree, and was one of the commonest underlying medical conditions among patients hospitalized with the 2009 pandemic influenza virus infection. Although respiratory virus infections are the major causes of asthma exacerbation, the mechanism by which influenza exacerbates asthma is poorly understood. Animal models of disease comorbidity are crucial to understanding host-pathogen interactions and elucidating complex pathologies. Existing murine models of influenza virus infection in asthmatics show that asthmatic mice are highly resistant to influenza virus infection, which contradicts clinical observations in humans. Here, we developed a murine model of influenza virus/asthma comorbidity using NC/Nga mice, which are highly sensitive to allergic reactions such as atopic dermatitis and allergic airway inflammation. This model was then used to examine the impact of allergic airway inflammation on lung pathology in the 2009 pandemic influenza virus infected mice. The results showed that induction of acute allergic airway inflammation in pre-existing influenza virus infection had additive effects on exacerbation of lung pathology, which mirrors findings in human epidemiological studies. In contrast, pre-existing allergic airway inflammation protected from subsequent influenza virus infection, which was compatible with those of previous murine models of influenza virus infection in asthmatic mice. These variable outcomes of this murine model indicate that the temporal relation between allergic airway inflammation and influenza virus infection might play a critical role in asthma and influenza comorbidity. Thus, this murine model will further our understanding of how influenza virus infection affects an

    Ribonucleic acids (RNAs) are very complex and their all functions have yet to be fully clarified. Noncoding genes (noncoding RNA, sequences, and pseudogenes) comprise 67% of all genes and they are represented by housekeeping noncoding RNAs (transfer RNA (tRNA), ribosomal RNA (rRNA), small nuclear RNA (snRNA), and small nucleolar RNA (snoRNA)) that are engaged in basic cellular processes and by regulatory noncoding RNA (short and long noncoding RNA (ncRNA)) that are important for gene expression/transcript stability. In this review, we summarize data concerning the significance of long noncoding RNAs (lncRNAs) in metabolic syndrome related disorders, focusing on adipose tissue and pancreatic islands.

    2008-01-01

    Recently in 2006, a group of experts in obsessive compulsive disorder (OCD) and obsessive compulsive-related disorders (OCRDs) convened in Washington, DC, to review existing data on the relationships between these various disorders, and to suggest approaches to address the gaps in our knowledge, in preparation for the upcoming Diagnostic and Statistical Manual (Fifth Edition) (DSM-V). As a result of this meeting, the Research Planning Agenda for DSM-V: OCRD Work Group suggested removing OCD from the anxiety disorders, where it is currently found. This proposal is in accordance with the current International Classification of Mental Disorders (ICD-10) classification of OCD as a separate category from the anxiety disorders. Although the ICD-10 places both OCD and the anxiety disorders under the umbrella category of "neurotic, stress-related, and somatoform disorders," they are two separate categories, distinct from one another. As OCD and other putative OCRDs share aspects of phenomenology, comorbidity, neurotransmitter/peptide systems, neurocircuitry, familial and genetic factors, and treatment response, it was proposed to create a new category in DSM-V entitled OCRDs. Alternatively, the OCRDs might be conceptualized as a new category within the broader category of anxiety disorders. Future studies are needed to better define the relationships among these disorders, and to study boundary issues for this proposed category. There are both advantages and disadvantages in creating a new diagnostic category in DSM-V, and these are discussed in this article.

    Sleep-related eating disorder (SRED) may have some common clinical features with sleepwalking and with eating behavior disorders. The objective of this study was to compare clinical, sleep, and eating behavior measures in patients with SRED vs. sleepwalkers and controls. Overall, 15 patients with SRED, 21 sleepwalkers, and 20 age- and sex-matched healthy volunteers underwent interviews, completed sleep, anxiety, depression, and eating behavior scales, and had a night-time videopolysomnography. Patients with SRED were mainly women, had disease onset in adulthood, suffered nightly episodes and insomnia, and had more frequent eating problems in childhood and higher current anorexia scores than sleepwalkers and controls. Unlike controls, they shared several commonalities with sleepwalkers, including a high frequency (66%) of past or current sleepwalking, a similar timing of parasomnia episodes during the first half of the night, numerous arousals from stage N3, and a similarly altered level of daytime sleepiness and anxiety, but higher awareness during parasomnia episodes. Conversely, only 10% of sleepwalkers ate during their sleepwalking episodes. On videopolysomnography, the eating episodes occurred mostly within 1min after awakening from stage N2 (n=9) or stage N3 (n=6). The frequencies of restless legs syndrome, periodic leg movements, and sleep apnea were similar across the three groups. Patients with SRED share several clinical commonalities with sleepwalkers (although their level of awareness is higher) plus former or current eating behavior problems. It suggests that they have specialized a former sleepwalking behavior toward sleep-related eating because they are more vulnerable to eating behavior problems during the daytime.

    2015-01-01

    Allergic inflammation is associated closely with parasite infection but also asthma and other common allergic diseases. Despite the engagement of similar immunologic pathways, parasitized individuals often show no outward manifestations of allergic disease. In this perspective, we present the thesis that allergic inflammatory responses play a primary role in regulating circadian and environmental inputs involved with tissue homeostasis and metabolic needs. Parasites feed into these pathways and thus engage allergic inflammation to sustain aspects of the parasitic life cycle. In response to parasite infection, an adaptive and regulated immune response is layered on the host effector response, but in the setting of allergy, the effector response remains unregulated, thus leading to the cardinal features of disease. Further understanding of the homeostatic pressures driving allergic inflammation holds promise to further our understanding of human health and the treatment of these common afflictions.

    Research indicates that stereotypes can intersect. For example, the intersection of stereotypes about gender and mental disorders could result in perceptions of gendered mental disorders. In the current research, Studies 1 and 2 showed that people view specific disorders as being masculine or feminine. The masculine stereotype included antisocial personality disorder, addictions, and paraphilias. The feminine stereotype included eating disorders, histrionic personality disorder, body dysmorphia, and orgasmic disorder. In both studies, the perception of disorders as masculine was positively correlated with stigma. Study 3 showed that the positive correlation between masculinity and stigma also occurred when examining specific symptoms rather than full mental disorders. The findings provide further evidence for the intersection of stereotypes and indicate a novel factor in the understanding of stigma.

    Imidazole dipeptides (ID), such as carnosine (β-alanyl-L-histidine), are compounds widely distributed in excitable tissues of vertebrates. ID are also endowed of several biochemical properties in biological tissues, including antioxidant, bivalent metal ion chelating, proton buffering, and carbonyl scavenger activities. Furthermore, remarkable biological effects have been assigned to such compounds in age-related human disorders and in patients whose activity of serum carnosinase is deficient or undetectable. Nevertheless, the precise biological role of ID is still to be unraveled. In the present review we shall discuss some evidences from clinical and basic studies for the utilization of ID as a drug therapy for age-related human disorders. PMID:26425391

    The present cross-sectional study investigated the relation among disordered eating-related cognition, psychological flexibility, and poor psychological outcomes among a nonclinical college sample. As predicted, conviction of disordered eating-related cognitions was positively associated with general psychological ill-health and emotional distress in interpersonal contexts. Disordered eating-related cognition was also inversely related to psychological flexibility, which was inversely related to poor psychological health and emotional distress in interpersonal contexts. The combination of disordered eating-related cognition and psychological flexibility accounted for the proportion of variance of these poor psychological outcomes greater than disordered eating-related cognition alone. Finally, psychological flexibility accounted for the proportion of variance of these negative psychological variables greater than did disordered eating-related cognition.

    The aim of this literature review is to assess the current state of knowledge regarding differences and similarities between the inattentive (IA) and combined (C) subtypes of Attention-Deficit/Hyperactivity Disorder (ADHD) in order to detail challenges concerning further conceptualization, diagnostics, and treatment. The literature on ADHD-IA and ADHD-C was reviewed and contrasted across genetic, neuroanatomical, neurophysiological/ neurochemical, neuro(psycho)logical, and clinical psychiatric measurement levels. It was found that the more fundamental the measurement level, the less unambiguous evidence is found for subtype differences. Only on the clinical psychiatric diagnostic level, do more or less clear-cut differences in cognitive, social, academic, and behavioural functioning emerge. In conclusion, fundamental research that compares ADHD-IA and ADHD-C is relatively rare. At this point, only irrefutable phenomenological evidence of subtype differences seems to be available, even in attention problems which are presumed to be identical. The question as to whether both subtypes should be considered as two independent disorders was not adequately resolved.

    Abstract Sleep-related movement disorders (SRMD) are sleep disorders. As poor sleep quality is associated with cognitive impairment, we hypothesized that SRMD patients were exposed to a great risk for developing dementia. The present study was aimed to retrospectively examine the association of SRMD and dementia risk. A retrospective longitudinal study was conducted using the data obtained from the Longitudinal Health Insurance Database (LHID) in Taiwan. The study cohort enrolled 604 patients with SRMD who were initially diagnosed and 2416 patients who were randomly selected and age/gender matched with the study group. SRMD, dementia, and other confounding factors were defined according to International Classification of Diseases Clinical Modification Codes. Cox proportional-hazards regressions were employed to examine adjusted hazard ratios (HR) after adjusting with confounding factors. Our data revealed that patients with SRMD had a 3.952 times (95% CI = 1.124–4.767) higher risk to develop all-cause dementia compared with individuals without SRMD. The results showed that SRMD patients aged 45 to 64 exhibited highest risk of developing all-cause dementia (HR: 5.320, 95% CI = 1.770–5.991), followed by patients age ≥65 (HR: 4.123, 95% CI = 2.066–6.972) and <45 (HR: 3.170, 95% CI = 1.050–4.128), respectively. Females with SRMD were at greater risk to develop all-cause dementia (HR: 4.372, 95% CI = 1.175–5.624). The impact of SRMD on dementia risk was progressively increased by various follow-up time intervals (<1 year, 1–2 years, and ≥2 years). The results suggest that SRMD is linked to an increased risk for dementia with gender-dependent and time-dependent characteristics. PMID:26705224

    Sensorimotor integration mechanisms can be affected by many factors, among which are those involving neuromuscular disorders. Parkinson's disease (PD) is characterized by well-known motor symptoms, among which lately have been included motor speech deficits. Measurement of the acoustic startle reflex (ASR) and its modulations (prepulse inhibition and prepulse facilitation, PPI and PPF respectively) represent a simple and quantifiable tool to assess sensorimotor function. However, it remains unknown whether measures of the PPI and PPF are associated with motor speech deficits in PD. A total of 88 subjects participated in this study, 52 diagnosed with PD and 36 control subjects. After obtaining written informed consent, participants were assessed with PPI at several interstimulus intervals, and PPF at 1000 ms using the SRH-Lab system (San Diego, CA). Percentage of change in the amplitude and latency of the ASR was analyzed between groups. Voice recordings were register of a specific text given to the subjects with a professional recorder and temporal patterns of speech were analyzed. Statistical analyses conducted in this study showed differences in PPI and PPF in subjects with PD compared to controls. In addition, discriminative parameters of voice abnormalities were observed in PD subjects related to control subjects showing a reduction in phonation time, vowel pulses, breaks, breakage and voice speech periods. PD presents a disruption in sensorimotor filter mechanisms and speech disorders, and there is a relationship between these alterations. The correlation between the PPI and PPF with an alteration of the voice in PD subjects contributes toward understanding mechanism underlying the neurophysiological alterations in both processes. Overall, easy and non-invasive tests such as PPI, PPF together with voice analysis may be useful to identify early stages of PD.

    To evaluate musculoskeletal disorders (MSDs), associated factors and treatment among dentists over a one year period. A total of 272 questionnaires were returned complete providing demographic information, details of the physical workload, location of pain in the body, and the treatment and prevention of MSDs. All data was coded for each of the parameters. The association between pain and each of the parameters was determined by parametric and non-parametric statistical tests (P < 0.05). General and specialist dentists participated in the study. The sample set of dentists consisted of 205 (75.4%) generalists and 67 (24.6%) specialists. Seventy-five percent of the total cohort experienced MSDs. Female dentists complained of pain significantly more frequently than their male counterparts (p=0.018). Significantly higher rates of pain and MSDs are related to increased years of work (r=0.168, p =0.017) and less regular ergonomic exercise (p=0.002). Reported pain was most common in the shoulder (44.2%), neck (31.8%) and lower back (29.9%). Dentists who worked inclined had significantly more pain disorder than those who did not (p=0.013). In total 23.5% of dentists reduced working hours and 16.5% sought medical help. Pain was most commonly reported in the shoulder, neck and back. Physical workload is an important factor in MSDs. The impact of MSDs on the work and life of dentists demonstrates the need for increased knowledge of MSDs and the instigation of preventive strategies.

    Given the array of biological changes induced by stressors, it is not surprising that these experiences may provoke a variety of illnesses. Among others things, stressors promote functional changes of neuropeptide and classical neurotransmitter systems. The peptidergic changes, for instance, include alterations of corticotropin releasing hormone, arginine vasopressin, and bombesin-like peptides at specific brain sites. Similarly some of the neurotransmitter systems influenced by stressors include GABAergic and monoamine functioning. Variations of these processes may limit neurogenesis (and dysregulation of growth factors such as BDNF) and influence cellular viability (through NFkappaB and MAP kinase pathways). As well, stressors activate the inflammatory immune system, notably the release of signaling molecules (cytokines), which may provoke many of the same neuropeptide (and other neurotransmitter) changes. By virtue of their actions on neuronal functioning, inflammatory processes may influence stress-related illness, such as depression, and may be a common denominator for the comorbidity that exists between depression and neurological conditions, including Parkinson's and Alzheimer's diseases, as well as cardiovascular-related pathology. The present report provides an overview of biological endophenotypes associated with stressors that are thought to be related to major depressive disorder and related comorbid conditions. The view is taken that synergy between stressors and inflammatory factors may promote pathological outcomes through their actions on neuropeptides and several neurotransmitters. As well, stressful events may result in the sensitization of neurochemical and cytokine processes, so that later re-exposure to these stimuli may promote rapid and exaggerated responses that favor illness recurrence.

    Epilepsy is common in Rett syndrome, an X-linked dominant disorder caused by mutations in the MECP2 gene, and in Rett-related disorders, such as MECP2 duplication. However, neither the longitudinal course of epilepsy nor the patterns of seizure onset and remission have been described in Rett syndrome and related conditions. The present study summarizes the findings of the Rett syndrome Natural History study. Participants with clinical Rett syndrome and those with MECP2 mutations without the clinical syndrome were recruited through the Rett Natural History study from 2006 to 2015. Clinical details were collected, and cumulative lifetime prevalence of epilepsy was determined using the Kaplan-Meier estimator. Risk factors for epilepsy were assessed using Cox proportional hazards models. Of 1205 participants enrolled in the study, 922 had classic Rett syndrome, and 778 of these were followed longitudinally for 3939 person-years. The diagnosis of atypical Rett syndrome with a severe clinical phenotype was associated with higher prevalence of epilepsy than those with classic Rett syndrome. While point prevalence of active seizures ranged from 30% to 44%, the estimated cumulative lifetime prevalence of epilepsy using Kaplan-Meier approached 90%. Specific MECP2 mutations were not significantly associated with either seizure prevalence or seizure severity. In contrast, many clinical features were associated with seizure prevalence; frequency of hospitalizations, inability to walk, bradykinesia, scoliosis, gastrostomy feeding, age of seizure onset, and late age of diagnosis were independently associated with higher odds of an individual having epilepsy. Aggressive behaviour was associated with lower odds. Three distinct patterns of seizure prevalence emerged in classic Rett syndrome, including those who did not have seizures throughout the study, those who had frequent relapse and remission, and those who had relentless seizures. Although 248 of those with classic Rett

    Allergic rhinitis (AR) is rarely found in isolation and needs to be considered in the context of systemic allergic disease associated with numerous comorbid disorders, including asthma, chronic middle ear effusions, sinusitis, and lymphoid hypertrophy with obstructive sleep apnea, disordered sleep, and consequent behavioral and educational effects. The coexistence of allergic rhinitis and asthma is complex. First, the diagnosis of asthma may be confused by symptoms of cough caused by rhinitis and postnasal drip. This may lead to either inaccurate diagnosis of asthma or inappropriate assessment of asthma severity with over treatment of the patient. The term "cough variant rhinitis" is therefore proposed to describe rhinitis that manifest itself primarily as cough that results from postnasal drip. Allergic rhinitis, however, has also a causal role in asthma; it appears both to be responsible for exacerbating asthma and to have a role in its pathogenesis. Postnasal drip with nasopharyngeal inflammation leads to a number of other conditions. Thus sinusitis is a frequent extension of rhinitis and is one of the most frequently missed diagnoses. Allergen exposure in the nasopharynx with release of histamine and other mediators can cause Eustachian tube obstruction possibly leading to middle ear effusions. Chronic allergic inflammation of the upper airway causes lymphoid hypertrophy with prominence of adenoidal and tonsillar tissue. This may be associated with poor appetite, poor growth, obstructive sleep apnea, mouth breathing, pharyngeal irritation and dental abnormalities. Allergic rhinitis is therefore part of a spectrum of allergic disorders that can profoundly affect the well being and quality of life of a child. Prospective cohort studies are required to assess the disease burden caused by allergic rhinitis in childhood, its consequences due to delay in diagnosis and treatment, and to further assess the potential educational impairment that may result.

    Here, we report on the prevalence of allergic conjunctivitis and positive skin prick test (SPT) results in relation to respiratory allergic conditions among patients with symptoms of allergies at a respiratory outpatient clinic. A questionnaire survey of symptoms (i.e., asthma-like, rhinitis, and conjunctivitis symptoms) involving 1522 patients was carried out. The responses of 1242 patients indicated that they had allergic conjunctivitis, asthma, rhinitis, or a combination of these conditions, and 869 of these patients underwent SPTs that assessed responses to 40 allergens. Allergic conjunctivitis was found to be very common (40%, 497 out of 1242 patients) among those with symptoms of allergies. Conjunctivitis was slightly more common among women, while rhinitis was more common among men. Patients with both conjunctivitis and rhinitis were more likely to undergo SPTs, and they had a higher rate of positive SPTs. The coexistence of two or more comorbidities increased the risk of having an immunoglobulin E (IgE)-mediated allergy (based on the SPT results) compared to having each of the conditions alone. In conclusion, allergic conjunctivitis can occur either alone or with asthma and/or rhinitis. It is not always accompanied by rhinitis, but the coexistence of these conditions was the strongest indicator of IgE-mediated allergies. PMID:28428968

    Some clinical studies have suggested a relationship between allergic diseases and gut microbiota. We aimed to study bifidobacterial colonization at species and strain levels in ten allergic French infants included at their first clinical consultation and 20 controls matching for age at sampling, mode of delivery, per partum antibiotics, type of feeding and antibiotics in the first weeks of life. The faecal microbiota was analyzed by culture methods and TTGE. Bifidobacterial species and strains were identified using multiplex PCR and Box-PCR fingerprinting. No differences were observed between groups in the number of colonized infants or in the levels of colonization by the main aerobic and anaerobic genera. All infants were colonized with high levels of Bifidobacterium except for one in each group. One to 5 Bifidobacterium species and 1 to 7 strains were observed per subject independently of allergic status and age at sampling. Our study showed the infants to be colonized by several species and strains, including several strains from the same species. This diversity in Bifidobacterium colonization was not related with the allergic status and showed that the link between Bifidobacterium colonization and allergic diseases is complex and cannot be restricted to the role attributed to Bifidobacterium species.

    There are occupational risks inherent to the activities of professional hairdressers, which are not frequently studied, and therefore not considered in the formulation of health policies for this group. To verify the prevalence of work-related musculoskeletal disorders (WRMDs) in hairdressers through symptom reports, to characterize the most frequently affected anatomical parts and to identify and analyse risk factors of WRMDs in hairdressing. A cross-sectional epidemiological study of 220 hairdressers from beauty parlours in São Paulo (Brazil) was carried out. Each hairdresser completed a self-administered questionnaire which included information on socio-demographic characteristics, working conditions and health-related musculoskeletal system complaints. Ergonomic analyses were also performed in six parlours. The prevalence of WRMDs was 71%. Risk factors were associated with psychosocial factors and factors related to discomfort and work fatigue such as lack of acknowledgement of work and uncomfortable posture at work [odds ratio (OR) = 3.54; 95% confidence interval (CI) 1.51-8.30], not feeling comfortable with body/neck/shoulders while working (OR = 2.78; 95% CI 1.40-5.54) and having >15 years of professional activity (OR = 3.04; 95% CI 1.17-7.91). Occupational risk factors associated with the development of WRMDs in hairdressers are related to biomechanical, organizational and psychosocial work factors. The high prevalence of WRMDs found highlights the importance of disseminating recommendations for prevention of symptoms with regards to the provision of suitable furniture, equipment and work tools, environmental conditions, size of workplace, work organization and psychosocial work factors.

    Playing a percussion instrument demands great force and effort, which may make percussionists prone to playing-related musculoskeletal disorders (PRMDs). Of all of the percussion instruments in India, tabla is the most popular. The present study was undertaken to investigate the prevalence of discomforts among professional tabla players. Eighty-five professional tabla players voluntarily participated in the study. The Nordic Musculoskeletal Questionnaire and visual analog scale were administered to all the participants. Demographic details, music-related activities, and symptoms of discomfort were also recorded. It was found that prone anatomical areas were the low back, right shoulder, neck, left shoulder, upper back, and knees. The frequency of discomfort was found to be mostly weekly for the shoulders and monthly for neck, low back, and knees. There was an association between visual analog scale and prevalence of self-reported discomforts in some body parts. It can be said that the prolonged, unsupported, folded-knee sitting posture may be the cause of discomforts.

    Substance-related disorders (SRDs) are a major cause of morbidity and mortality worldwide. Family, twin, and adoption studies have demonstrated the substantial heritability of SRDs. To determine the impact of genetic variation on risk for SRD and the response to treatment, researchers have conducted a number of secondary data analyses and quasi-experimental studies that target one or more candidate gene variants. This review examines studies in which candidate polymorphisms were examined as mediator variables to identify pharmacogenetic effects on subjective responses to drug administration or cues or outcomes of medication trials for SRDs. Efforts to use a meta-analytic approach to quantify these effects are premature because the number of available studies using similar methods and outcomes is limited, so the present review is qualitative. Findings from these studies provide preliminary evidence of clinically relevant pharmacogenetic effects. However, independent replication of these findings has been sparse. Although this growing body of literature has produced conflicting results, improved statistical controls may help to clarify the findings. Additionally, the use of empirically derived sub-phenotypes (i.e., which serve to differentiate distinct groups of affected individuals) may also help to identify genetic mediators of pharmacologic response in relation to SRDs. The identification of genetic mediators can inform clinical care both by identifying risk factors for SRDs and predicting adverse events and therapeutic outcomes associated with specific pharmacotherapies.

    Prevalence of both diabetes mellitus and obstructive sleep apnea (OSA) is high among general population. Both of these conditions are associated with significant morbidity. OSA affects approximately 25% of men and 9% of women, and its prevalence is even higher among obese, Hispanics, African American and diabetic patients. Diabetes on the other hand besides having high prevalence in general population has even higher prevalence among ethnic populations as Hispanics and African American. Despite the availability of several simple screening tools for OSA, as Berlin questionnaire, STOP-BANG questionnaire, NAMES Criteria, the utility for screening of OSA among the diabetic population remains marginal. This in turn can lead to significant morbidity and complications related to OSA as well as worsening of diabetes mellitus and increase in diabetic complications due to untreated sleep related breathing disorder. It is therefore imperative for the primary care giver to screen for OSA among the diabetic population as a part of their routine evaluation to prevent worsening of diabetes, and its cardiovascular, renal, ophthalmologic and neurological complications.

    The present review provides an update of the biological actions of Pycnogenol® in the treatment of metabolic syndrome and related disorders such as obesity, dyslipidaemia, diabetes and hypertension. Pycnogenol® is a French maritime pine bark extract produced from the outer bark of Pinus pinaster Ait. Subsp. atlantica. Its strong antioxidant, antiinflammatory, endothelium-dependent vasodilator activity, and also its anti-thrombotic effects make it appropriate for targeting the multifaceted pathophysiology of metabolic syndrome. Clinical studies have shown that it can reduce blood glucose levels in people with diabetes, blood pressure in mild to moderate hypertensive patients, and waist circumference, and improve lipid profile, renal and endothelial functions in metabolic syndrome. This review highlights the pathophysiology of metabolic syndrome and related clinical research findings on the safety and efficacy of Pycnogenol®. The results of clinical research studies performed with Pycnogenol® are discussed using an evidence-based, target-oriented approach following the pathophysiology of individual components as well as in metabolic syndrome overall.

    Curcumin, or diferuloylmethane, is a crystalline compound which gives the East Asian spice turmeric its bright yellow color. The medicinal properties of this spice have been referenced in numerous countries and cultures throughout the world. Today, there is growing scientific evidence suggesting curcumin's utility in the treatment of chronic pain, inflammatory dermatoses, acceleration of wound closure, skin infections, as well as cosmetic ailments such as dyspigmentation. In addition, curcumin may have a protective role against various pollutants and cytotoxic agents, indicating that it may be beneficial in a mitigational or prophylaxis role. Although turmeric has been used for thousands of years in alternative medicine, curcumin has yet to emerge as a component of our mainstream dermatologic therapeutic armamentarium. Interestingly, curcumin provides an ideal alternative to current therapies because of its relative safety profile even at high doses. Although the advantageous properties of curcumin in medicine are well established, its therapeutic potential thus far has been limited because of its poor oral bioavailablity. Topical administration of curcumin can directly deliver it to the affected tissue making it useful in treating skin-related disorders. However, limitations still exist such as the cosmetically unpleasing bright yellow-orange color, its poor solubility, and its poor stability at a high pH. Here the current literature detailing the potential and current use of curcumin in dermatology is reviewed.

    2007-01-01

    Allergic rhinitis is the most common atopic disorder seen in the outpatient clinic setting diagnosed by history, physical exam and objective testing. According to the Allergic Rhinitis and its Impact on Asthma (ARIA) document, it is classified by chronicity (intermittent or persistent), and severity which is based on symptoms and quality of life (mild, or moderate/severe). It has enormous socioeconomic costs and significant reduction in quality of life. Allergen avoidance should be implemented, particularly in children, to reduce level of exposure; unfortunately efforts are often inadequate. Montelukast, a novel medication, is an antagonist to the leukotriene receptor. It is nonsedating, dosed once daily, and has a safety profile similar in adults and children with approval down to 6 months of age. A review of the literature undoubtedly establishes montelukast as a viable alternative for the treatment of seasonal allergic rhinitis. Its benefits are equivalent to antihistamines, when used as monotherapy, but less than intranasal corticosteroids. The addition of an antihistamine to montelukast does appear to have added benefits and at times is reported to be equivalent to intranasal corticosteroids. PMID:18360641

    Incidence of allergic disorders in children has increased significantly over time due to environmental and life-style changes. These include allergic rhinitis, atopic dermatitis, allergic conjunctivitis, food allergies, bronchial asthma, drug allergies, insect bites and anaphylaxis; most being IgE-mediated type 1 hypersensitivity reactions to common environmental and food antigens. Although most of them are self-limiting, they may adversely affect the quality of life and sometimes become life-threatening as well. These conditions are more likely to get underestimated, or over-diagnosed as recurrent infections. Hence a careful history and physical examination by attending pediatrician are necessary to differentiate it from infections. Diagnostic tests have limited value in identifying the inciting allergen. Management includes avoidance of the inciting allergens (if known), combined with symptomatic relief provided by a combination of pharmacological agents, e.g., antihistamines, anticholinergics, chromones, leukotriene-modifying agents, topical and systemic steroids. Further, specialist consultation needs to be sought, for children with recurrent or persistent symptoms. The scope of this manuscript does not include bronchial asthma.

    Premenstrual symptoms are common among young menstruating women, but the psychiatric disorder premenstrual dysphoric disorder (PMDD) is seen only in approximately 3% of this group. The symptom profile of PMDD has been empirically derived from a number of investigations including a large data base from five university centers. The most commonly reported symptoms are depression and mood swings, but a substantial number of women report tension and anxiety. Lifetime psychiatric illness is also common in women with PMDD, and although mood disorders predominate, past histories of anxiety disorders are also common, further suggesting an association between PMDD and anxiety disorders. The strongest data supporting such an association lie with challenge studies that have been used to provoke panic in panic patients and are effective in precipitating panic attacks in women with PMDD. Finally, treatments that are effective for anxiety disorders are also useful in the treatment of PMDD. In this paper, the above outlined relationship between anxiety disorders and PMDD is reviewed.

    Allergic contact dermatitis (ACD) is a common skin disease caused by a T cell-mediated immune reaction to usually innocuous allergens. ACD can have grave medical and socioeconomic consequences. ACD and irritant contact dermatitis often occur together. A detailed history and clinical examination are crucial and guide patch testing, which is the gold standard to diagnose ACD. T-cell clones persisting in the skin may explain the tendency of ACD to relapse even after years of allergen avoidance. Traditional treatments for ACD are topical steroids, calcineurin inhibitors, phototherapy, retinoids (including the recent alitretinoin), and immunosuppressants. Targeted therapies are lacking.

    Allergic bronchopulmonary aspergillosis (ABPA) is caused by an exaggerated T(H)2 response to the ubiquitous mold Aspergillus fumigatus. ABPA develops in a small fraction of patients with cystic fibrosis and asthma, suggesting that intrinsic host defects play a major role in disease susceptibility. This article reviews current understanding of the immunopathology, clinical and laboratory findings, and diagnosis and management of ABPA. It highlights clinical and laboratory clues to differentiate ABPA from cystic fibrosis and asthma, which are challenging given clinical and serologic similarities. A practical diagnostic algorithm and management scheme to aid in the treatment of these patients is outlined.

    A 42 year old male presents with worsening pain and an increase in thick chronic drainage of the left sinus. Image studies show complete opacification of the left frontal sinus, left sphenoid sinus, and the left maxillary sinus. The patient was taken to the operating room and tissue for microscopic evaluation was obtained. The microscopic findings were classic for allergic fungal sinusitis: areas of alternating mucinous material and inflammatory cell debris and abundant Charcot-Leyden crystals. Cultures were performed and the patient began steroid therapy and desensitization therapy.

  11. Ocular allergic inflammation: interaction between the cornea and conjunctiva.

    Severe ocular allergic diseases such as vernal keratoconjunctivitis are characterized not only by conjunctival allergic inflammation, including infiltration of T helper 2 cells and eosinophils into the conjunctiva, but also by various corneal disorders such as persistent epithelial defects and shield ulcer. Although the cornea and conjunctiva are thought to influence each other during ocular allergic inflammation, direct evidence for interaction between these tissues in vivo has been lacking. Eosinophils and eosinophil-derived factors are implicated in the pathogenesis of corneal lesions associated with ocular allergy, with cytotoxic granule proteins such as major basic protein and matrix metalloproteinase 9 derived from eosinophils having been detected in shield ulcer. Major basic protein exhibits cytotoxic effects in cultured corneal epithelial cells and inhibits corneal epithelial wound healing in organ culture, whereas matrix metalloproteinase 9 can degrade the corneal epithelial basement membrane. In vitro studies have revealed that cytokines and other inflammatory mediators directly impair the barrier function of corneal epithelial cells and increase the expression of chemokines and adhesion molecules by corneal stromal fibroblasts, effects that may enhance allergic inflammation. We have recently shown that removal of the corneal epithelium augmented late-phase clinical signs and conjunctival eosinophilia, whereas conjunctival inflammation delayed corneal epithelial wound healing, in a rat model of ocular allergy. Conjunctival allergic inflammation and corneal epithelial disorders thus interact with each other in vivo to generate a vicious cycle, interruption of which might provide the basis for novel approaches to the treatment of severe ocular allergy.

    The home environment can influence childhood allergies and respiratory health but there is little information on associations between early life exposure at home and new onset and remission of the asthmatic or allergic symptoms in preschool children. A questionnaire survey was performed in a random cluster sample of 4246 preschool children in Urumqi, China. Information on the home environment (perceptions of odors and indicators of pollution sources) and children's health (wheeze, rhinitis and eczema) was collected for the first 2 years of life and the last year (before answering the questionnaire) from one of the parents or another guardian of the child. Associations between the home environment the first 2 years of life and new onset and remission of childhood symptoms were analyzed by multiple logistic regression. Home environment factors reported for the first 2 years of life were consistently positively associated with new onset of symptoms and negatively associated with remission of symptoms. Visible mold (OR 1.46, 95% CI 1.12-1.90), moldy odor (OR 2.15, 95% CI 1.45-3.18), air dryness (OR 1.31, 95% CI 1.08-1.59), stuffy odor (OR 1.25, 95% CI 1.01-1.54) and parental smoking (OR 1.36, 95% CI 1.13-1.65) were associated with new onset of symptoms. These factors were negatively associated with the remission of symptoms. In conclusion, mold contamination at home (moldy odor/visible mold), poor indoor air quality (stuffy odor, air dryness) and exposure to environmental tobacco smoke (ETS) in the first 2 years of life can increase the incidence of asthmatic and allergic symptoms and decrease the remission from these symptoms in preschool children.

    Allergic diseases, such as allergic asthma, allergic rhinitis, atopic dermatitis, conjunctivitis, urticaria, food allergy, and/or anaphylaxis, are associated with the skewing of immune responses towards a T helper 2 (TH2) phenotype, resulting in eosinophilic inflammation. TH2 cytokines, such as interleukin (IL)-4, IL-5 and IL-13, promote IgE production, mast cell differentiation, and eosinophil growth, migration and activation which then lead to the pathologic abnormalities in allergic diseases. Moreover, the impaired function of regulatory T cells has been noted in allergic diseases. To date, treatments for allergic diseases, such as antihistamines, corticosteroids, bronchodilators and some allergen-specific immunotherapy, are effective but costly and require long-term and recurrent drug administration. Gene therapy has been shown to be an easy, effective, and convenient treatment by delivering the allergen or the therapeutic protein in the form of plasmid DNA in vivo to modulate allergic immune responses. We summarize here the recent advances of gene therapy in allergic diseases and discuss the challenges in clinical application.

  18. Impulsivity-related traits and their relation to DSM-5 section II and III personality disorders.

    Difficulties with impulse control are considered a core feature of personality disorders (PDs) as assessed by the Diagnostic and Statistical Manual of Mental Disorders (5th edition [DSM-5]; American Psychiatric Association, 2013). Despite this, there has been relatively little examination of the manner in which DSM-5 PDs are characterized by multidimensional models of impulsivity that parse this broad umbrella construct into smaller, more unidimensional constructs. Using the UPPS model and measure of impulsivity (Whiteside & Lynam, 2001), the relations between 4 impulsivity-related traits and interview-rated scores on both DSM-5 Section II and III PDs and PD traits were examined in a community sample of individuals currently receiving psychological or psychiatric care (N = 106). As expected, the UPPS traits manifested correlations with the new Section III trait model that were generally consistent with the assertion that this new DSM-5 trait model reflects a pathological variant of the Five-Factor Model (FFM; e.g., UPPS traits associated with FFM conscientiousness were most strongly related to DSM-5 disinhibition traits). Overall, the UPPS traits accounted best for variance in DSM-5 Section II and III Cluster B PDs, consistent with these PDs being characterized, in part, by emotionally and cognitively based forms of impulsivity.

    The present study was conducted to investigate the prevalence of musculoskeletal disorders and eye and vision complaints among the computer users of King Abdulaziz University (KAU), Saudi Arabian Airlines (SAUDIA), and Saudi Telecom Company (STC). Stratified random samples of the work stations and operators at each of the studied institutions were selected and the ergonomics of the work stations were assessed and the operators' health complaints were investigated. The average ergonomic score of the studied work station at STC, KAU, and SAUDIA was 81.5%, 73.3%, and 70.3, respectively. Most of the examined operators use computers daily for ≤ 7 hours, yet they had some average incidences of general complaints (e.g., headache, body fatigue, and lack of concentration) and relatively high level of incidences of eye and vision complaints and musculoskeletal complaints. The incidences of the complaints have been found to increase with the (a) decrease in work station ergonomic score, (b) progress of age and duration of employment, (c) smoking, (d) use of computers, (e) lack of work satisfaction, and (f) history of operators' previous ailments. It has been recommended to improve the ergonomics of the work stations, set up training programs, and conduct preplacement and periodical examinations for operators. PMID:25383379

    Biases in causal attributions and evidence integration have been implicated in delusions, but have not been investigated simultaneously to examine additive or multiplicative effects. It was hypothesised that paranoid delusions would correlate with self-serving and personalising biases ("defence" model of paranoia), particularly when these biases were disconfirmed. Constrained principal component analysis was used to investigate differences between schizophrenia patients (paranoid vs. non-paranoid), bipolar disorder patients, and healthy controls, as well as to examine the extent to which psychotic symptoms could predict patterns of responding on a novel attributional bias task (Attributional Style BADE, or ASB) that requires integrating contextual information. Although no group differences were found, disorganisation and manic symptoms correlated with situation attributions and self-blame when such attributions were unsupported by the available evidence, and depression and anxiety correlated with other-person and self attributions (not situation attributions) when confirmed by the available evidence, regardless of diagnosis. While group differences accounted for little variance in responses on the ASB task, a transdiagnostic association between symptoms of psychosis and the ASB task was observed. This highlights the importance of considering symptom profiles rather than diagnostic groupings when investigating cognitive biases and related non-pharmacological treatments.

    Anaesthesiology is a specialty whose specificity of the working process results in high levels of stress as an inevitable condition - a particularly worrying situation in the daily life of these professionals. This study, based on data from national and international literature, aims to discuss the basis of the occurrence of mental and behavioural disorders or of psychopathological injuries (psychological distress) related to working activity in anesthesiologists. A literature review was conducted, with papers selected from Medline and Lilacs databases, published between 2000 and 2012 in Portuguese, English and Spanish, and addressing the possible association between occupational hazards of the anaesthesiologist profession and mental health problems and psychic distress. Twenty-six publications were listed. Several aspects of the anesthesiologist's work are important points to better understand the relationship between mental health at work and working organization. Poor temporal structuring of work, conflictuous interpersonal relationships and poor control over the activity itself may be mentioned as illness enhancers. The working organization, when not appropriate, is an important occupational risk factor for the life and mental health of workers, mainly of professionals focused on the care of people. This paper focuses on anesthesiologists, who are constantly exposed to stressful and anxiogenic factors. Copyright © 2014 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

  3. Prevention and management of work-related cardiovascular disorders.

    Cardiovascular disorders (CVDs) constitute a major burden for health of working populations throughout the world with as much as 50% of all causes of death and at least 25% of work disability. There are some changes in CVD risk factors among occupational classes. This is mainly due to the new types of work-related causes of morbidity associated with the recent developments in global work life, particularly in the industrialized countries. Meanwhile, in the developing countries or those in transition (e.g., in Eastern Europe), CVD mortality is increasing due to major socioeconomic changes, the demographic transition and rapid industrialisation and urbanisation, all leading to growing challenges to cardiovascular health. Better control of known risk factors (i.e., smoking, obesity, physical inactivity, high cholesterol, high blood pressure, and high blood glucose) is effective to prevent CVD incidence. But the expected improvement has not been achieved. The obstacles of achieving such impact are due to lack of awareness, lack of policies and their implementation into practice and shortage of infrastructures and human resources. These are needed for wide-scale and long-term programme implementation. Considering the WHO Global Strategy on Occupational Health for All, the WHO Global Action Plan on Workers' Health, the WHO Programme on Prevention of Non-communicable Diseases and the ILO Decent Work agenda, the 6th ICOH International Conference on Work Environment and Cardiovascular Diseases adopted the Tokyo Declaration.
