PURPOSE OF REVIEW To illustrate the frequency and trends of the comorbidity of epilepsy and dementia and the effects of antiepileptic drugs (AEDs) on cognitive functions. RECENT FINDINGS Although the mortality and incidence of epilepsy are decreasing overall, they are increasing in the elderly as a result of population growth and increased life expectancy. Alzheimer's disease and other dementias are among the commonest causes of seizures and epilepsy. Epilepsy can be also complicated by cognitive impairment, suggesting a bidirectional association. Although epilepsy with onset in the elderly can be the manifestation of a CNS disease/injury, the cause of cognitive impairment is multifactorial and includes static (genetic background, age at seizure onset, developmental and acquired cerebral lesions) and dynamic factors [recurrent seizures, epileptiform discharges, type and number of AEDs and psychiatric comorbidities]. find more , with special reference to first-generation drugs, have negative effects on cognitive functions; however, none was found to increase the risk of dementia. SUMMARY A net increase in the burden of epilepsy, dementia and epilepsy-dementia comorbidity is expected. The growing use of second-generation AEDs might help reducing adverse cognitive effects. However, the fairly high cost of these drugs might delay their widespread use in resource-poor countries. VIDEO ABSTRACT http//links.lww.com/CONR/A49.PURPOSE OF REVIEW The aim of this review is to highlight the conceptual and practical knowledge for interpreting score changes in patient-reported outcomes (PROs) that have been validated for chronic spontaneous urticaria (CSU). RECENT FINDINGS The urticaria guidelines recommends to assess PROs as Health-Related Quality of Life, disease activity and disease control, to detect the CSU impact and the overall treatment effect. To this aim it is crucial to determine the minimal important difference (MID) to assess if changes in questionnaire scores represent either perceived improvement or deterioration for patients. Methods for establishing the MID are well defined and are clustered into two broad categories distribution-based and anchor-based. SUMMARY For the majority of the available questionnaires for CSU, an MID has been defined, according to the results of various approaches. In most of the studies in our review, anchor-based methods, either alone or in combination with distribution ones, were used. The available information regarding MIDs across validated tools for CSU patients helps to interpret measurement scores and allows the implementation of PROs in routine practices.PURPOSE OF REVIEW Angioedema without urticaria is composed of an increasing subtype's variety and presents a challenging diagnosis. This review summarizes the subtypes recently described and subsequent new findings helpful within their classification. RECENT FINDINGS New methods to measure cleaved high molecular weight kininogen and activated plasma kallikrein have emerged as potential biochemical tests to identify bradykinin-mediated angioedema. #link# Three new subtypes of hereditary angioedema (HAE) with normal C1 inhibitor were described in the past two years HAE due to mutation in plasminogen gene, in kininogen gene, and in angiopoietin-1 gene; implicating the fibrinolytic and contact systems, and the regulation of vasculature, respectively. The understanding of some mechanisms in angioedema has been improved, compatible to the dominant-negative for some C1 inhibitor variants; furthermore, the increased activation of truncated F12 mutants by plasma kallikrein; and the diminished binding of angiopoietin-1 to its receptor. SUMMARY The validation of biomarkers for the contact system activation could be beneficial in differentiating bradykinin - from histaminergic-mediated angioedema. Currently, the available laboratorial tests are still somewhat restricted to the evaluation of the complement activation and the mediators of nonhistaminergic and nonbradykinin-mediated angioedema remain to be identified.PURPOSE OF REVIEW Allergic diseases are prototypic examples for gene × environment-wide interactions. This review considers the current evidence for genetic and epigenetic mechanisms in allergic diseases and highlights barriers and facilitators for the implementation of these novel tools both for research and clinical practice. RECENT FINDINGS The value of whole-genome sequencing studies and the use of polygenic risk score analysis in homogeneous well characterized populations are currently being tested. Epigenetic mechanisms are known to play a crucial role in the pathogenesis of allergic disorders, especially through mediating the effects of the environmental factors, well recognized risk modifiers. There is emerging evidence for the immune-modulatory role of probiotics through epigenetic changes. Direct or indirect targeting of epigenetic mechanisms affect expression of the genes favouring the development of allergic diseases and can improve tissue biology. The ability to specifically edit the epigenome, especially using the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology, holds the promise of enhancing understanding of how epigenetic modifications function and enabling manipulation of cell phenotype for research or therapeutic purposes. SUMMARY Additional research in the role of genetic and epigenetic mechanisms in relation to allergic diseases' endotypes is needed. An international project characterizing the human epigenome in relation to allergic diseases is warranted.PURPOSE OF REVIEW Although several reviews concerning diagnosis and treatment of eosinophilic esophagitis (EoE) have been presented, there are few in regard to eosinophilic gastroenteritis (EGE). Fortunately, findings related to epidemiology, as well as diagnosis and treatment of this disease have recently been increasing. RECENT FINDINGS The rates of incidence of both EoE and EGE have been reported to be increasing. For accurate diagnosis, plasma concentrations of thymic stromal lymphopoietin and IL-33 may be useful as biomarkers, though consensus has not been reached, while increased eosinophil infiltration in gastrointestinal tissue remains a critical factor. Topical glucocorticoid administration, an elimination diet, and molecular target therapy with neutralizing antibodies are potentially effective therapies that have recently been evaluated. SUMMARY As seen with other allergic diseases, EGE seems to be increasing. Several research projects regarding diagnosis and treatment of the disease are currently in progress.
