Abstract
Skin perceives and reacts to external mechanical forces to create resistance against the external environment. Excessive or inappropriate stimuli of pressure may lead to cellular alterations of the skin and the development of both benign and malignant skin disorders. We conducted a comprehensive literature review to delve into the pressure-induced and aggravated skin disorders and their underlying pressure-related mechanisms. Dysregulated mechanical responses of the skin give rise to local inflammation, ischemia, necrosis, proliferation, hyperkeratosis, impaired regeneration, atrophy, or other injurious reactions, resulting in various disease entities. The use of personal devices, activities, occupations, weight bearing, and even unintentional object contact and postures are potential scenarios that account for the development of pressure-related skin disorders. The spectrum of these skin disorders may involve the epidermis (keratinocytes and melanocytes), hair follicles, eccrine glands, nail apparatuses, dermis (fibroblasts, mast cells, and vasculature), subcutis, and fascia. Clarifying the clinical context of each patient and recognizing how pressure at the cellular and tissue levels leads to skin lesions can enhance our comprehension of pressure-related skin disorders to attain better management.

Prevalence, Clinical Manifestations, Treatment, and Clinical Course of Chronic Urticaria in Elderly: A Systematic Review. J Asthma Allergy 2022; 15:1455-1490.

Abstract
Purpose Data specific to the epidemiology, clinical features, and management of chronic urticaria (CU) in the geriatric population remain limited and not well understood. We aim to systematically review the prevalence, clinical manifestations, treatment, and clinical course of elderly patients with CU. Patients and methods Original articles that included data of elderly (aged >60 years) with CU that were published until February 2021 were searched in PubMed, Scopus, and Embase using predfefined search terms. Related articles were evaluated according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. Results Among the included 85 studies and 1,112,066 elderly CU patients, most (57.4%) were women. The prevalence of elderly CU in the general population ranged from 0.2–2.8%, and from 0.7–33.3% among all CU patients. Compared to adult CU, elderly CU patients had a higher percentage of wheal alone (73.9%), and lower rate of positive autologous serum skin test and atopy. Gastrointestinal diseases were the most common comorbidity (71.9%), and there was a high rate of malignancies and autoimmune diseases. Second generation H1-antihistamines were commonly used, and achievement of complete control was most often reported. Omalizumab was prescribed in 59 refractory patients, and a significant response to treatment was reported in most patients. The treatment of comorbidities also yielded significant improvement in CU. Conclusion Elderly CU was found to be different from adult CU in both clinical and laboratory aspects. H1- antihistamines are effective as first-line therapy with minimal side-effects at licensed doses. Treatment of secondary causes is important since the elderly usually have age-related comorbidities.

Abstract
This is Part 1 of an updated follow-up review of a World Allergy Organization (WAO) position paper published in 2012 on the diagnosis and treatment of urticaria and angioedema. Since 2012, there have been advances in the understanding of the pathogenesis of chronic urticaria, and greater experience with the use of biologics, such as omalizumab, in patients with severe refractory disease. For these reasons, the WAO decided to initiate an update targeted to general practitioners around the world, incorporating the most recent information on epidemiology, immunopathogenesis, comorbidities, quality of life, clinical case presentations, and the management of chronic spontaneous and chronic inducible urticaria, including urticaria in special situations such as childhood and pregnancy. A special task force of WAO experts was invited to write the different sections of the manuscript, and the final document was approved by the WAO Board of Directors. This paper is not intended to be a substitute for current national and international guidelines on the management of urticaria and angioedema but to provide an updated, simplified guidance for physicians around the world who manage patients with this common ailment.

Abstract
BACKGROUND In chronic spontaneous urticaria (CSU), the guidelines recommend very limited diagnostic procedures during the routine workup, although additional investigations might be indicated in some patients with CSU. For physicians treating patients with CSU, it is often difficult to decide which diagnostic tests are useful. OBJECTIVE To provide recommendations on what diagnostic tests should be performed on which patients with CSU. METHODS We performed an extensive literature search on the respective topics and identified relevant questions that should prompt diagnostic procedures based on the published evidence and expert consensus among all authors. RESULTS We provide questions, diagnostic testing, where appropriate, and recommendation that should be included when assessing the history of a patient with CSU, to explore and rule out differential diagnoses, to assess patients for underlying causes and modifying conditions, to explore patients for comorbid diseases and consequences of having CSU, and to assess patients for CSU components that can help to predict their disease course and response to treatment. CONCLUSIONS Here, we provide physicians treating patients with CSU with information about which clues should lead to which tests and why.

Abstract
BACKGROUND Delayed pressure urticaria (DPU) is characterized by recurrent erythematous and often painful swelling after the skin is exposed to sustained pressure. Treatment is challenging. Antihistamines, the first-line and only approved treatment, are often not effective. OBJECTIVE To systematically review the treatment options for DPU. METHOD A literature search of electronic databases for all relevant articles published till April 29, 2019, was conducted using the search terms "delayed pressure urticaria" and "pressure urticaria." This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. RESULTS Twenty-one studies (8 randomized controlled trials [RCTs], 10 retrospective cohort studies, and 3 open-label prospective studies) were included. Second-generation H1 antihistamines (sgAHs) were effective in 3 RCTs. The combination of an sgAH and montelukast (2 RCTs) or an sgAH and theophylline (1 non-RCT) was more effective than the sgAH alone. The disease improved with omalizumab (4 non-RCTs), sulphones (3 non-RCTs), oral prednisolone (1 RCT and 2 non-RCTs), intravenous immunoglobulin (1 non-RCT), and gluten-free diet (1 non-RCT). There are no studies on updosing of antihistamines over standard dosage in DPU. CONCLUSIONS Overall, the quality of studies on DPU is low. Because of the lack of other evidence, antihistamines remain the first-line therapy. Updosing of sgAHs could be considered in patients with uncontrolled symptoms on the basis of the extrapolation of evidence from chronic spontaneous urticaria, even though there is no evidence of its efficacy over standard dosage. Addition of montelukast may be considered. Omalizumab or sulphones may be used in treatment-resistant patients. High-quality DPU studies should be conducted.

Abstract
Chronic inducible urticaria (CIndU) is a group of chronic urticarias characterized by the appearance of recurrent wheals, recurrent angioedema or both, as a response to specific triggers. CIndU includes both physical (symptomatic dermographism, cold and heat urticaria, delayed pressure urticaria, solar urticaria, and vibratory urticaria) and nonphysical urticarias (cholinergic urticaria, contact and aquagenic urticaria). Here, we review the different forms of CIndU with an emphasis on symptomatic dermographism, cold urticaria, cholinergic urticaria, and delayed pressure urticaria. We discuss the clinical features, the diagnostic workup including provocation and threshold testing, and available treatment options.

Abstract
Chronic urticaria (CU) is a disease characterized by pruritic weals, angio-oedema or both occurring for at least 6 weeks. It encompasses spontaneous and inducible urticarias. The national and international guidelines outline the principles of treatment. Omalizumab, an anti-immunoglobulin E monoclonal antibody, has transformed the management of many severe and treatment-refractory patients. However, current UK guidance on its use does not address the needs of those with less severe disease, inducible urticarias, idiopathic histaminergic angio-oedema without weals as a presentation of CU and omalizumab non-responders. Our algorithm and a summary of the evidence to support its principles offers guidance and a more systematic targeted approach to using a range of 'off-label' agents for specific phenotypes of CU. It will be of use when guideline-recommended mast cell mediator antagonists fail to control symptoms and/or using omalizumab is ineffective, not practical or unfunded.

Abstract
PURPOSE OF REVIEW This review aims to update the information available on the prevalence, clinical picture, diagnostic methods, and treatment of urticarias induced by external physical stimuli. RECENT FINDINGS Physical urticarias are present in up to 5% of the general population, and in 10 to 50% of patients with chronic urticaria. Recent investigations have provided evidence that the presence of physical urticaria alone or when comorbid with chronic spontaneous urticaria is associated with a worse prognosis and duration. Most frequent subtypes of physical urticaria are dermographism and delayed pressure urticaria. The diagnosis is established through specific provocation tests and the management encompasses avoidance measures, pharmacologic therapy with nonsedating antihistamines, and alternative medications in refractory cases.

Abstract
BACKGROUND Omalizumab, a recombinant anti-IgE antibody, effectively treats chronic spontaneous urticaria. Evidence is lacking in patients with chronic inducible urticarias (CIndUs), which are frequently H1-antihistamine resistant. OBJECTIVE From the current published literature, we aimed to determine the strength of evidence for omalizumab efficacy and safety in the treatment of CIndUs. METHODS We performed a PubMed search to identify evidence on omalizumab use in the following 9 CIndU subtypes: symptomatic dermographism, cold urticaria, delayed-pressure urticaria, solar urticaria, heat urticaria, vibratory angioedema, cholinergic urticaria, contact urticaria, and aquagenic urticaria. RESULTS Forty-three trials, case studies, case reports, and analyses were identified. Our review indicates that omalizumab has substantial benefits in patients with various CIndUs. The evidence is strongest for symptomatic dermographism, cold urticaria, and solar urticaria. Little/no evidence was available on vibratory angioedema and aquagenic and contact urticaria. Our review supports rapid onset of action demonstrated through early symptom control in most cases, sometimes within 24 hours. Many patients gained complete/partial symptom relief and substantially improved quality of life. Adverse events were generally low, with omalizumab being well tolerated by most patients, including children. CONCLUSIONS A strong body of evidence supports the use of omalizumab in the treatment of patients with therapy-refractory CIndU. More data from randomized controlled studies are warranted.

Abstract
Omalizumab is a recombinant humanized monoclonal antibody that inhibits immunoglobulin E. It has been approved for the treatment of severe asthma and chronic spontaneous urticaria refractory to other treatments. Its use in the management of chronic inducible urticaria (a type triggered by certain stimuli) is still considered off-label, although this use has been discussed in some consensus papers. This review brings together case reports and case series describing the use of omalizumab to treat chronic inducible urticaria. We analyze the most important aspects of the cases and the outcomes reported. The results seem to position omalizumab as a potentially effective, safe treatment alternative in some cases of chronic inducible urticaria.

Abstract
These recommendations for the definition, diagnosis and management of chronic inducible urticaria (CIndU) extend, revise and update our previous consensus report on physical urticarias and cholinergic urticaria (Allergy, 2009). The aim of these recommendations is to improve the diagnosis and management of patients with CIndU. Our recommendations acknowledge the latest changes in our understanding of CIndU, and the available therapeutic options, as well as the development of novel diagnostic tools.

Abstract
Inducible urticaria is a heterogeneous group of skin disorders characterized by the appearance of wheals, pruritus and/or angioedema, sometimes accompanied by systemic symptoms caused by innocuous stimuli (cold, heat, pressure, etc.). This group of disorders compromises people's quality of life and most of the literature in this regard comes from case reports and case series since its epidemiology has been poorly studied and some cases are very rare. The aim of this review is to show an up-to-date overview of the available literature for various types of inducible urticarias, always beginning with an illustrative case and then describing their pathophysiological mechanisms, clinical manifestations, and treatment.

Abstract
In the recently published 2013 revision of the guidelines of urticaria, chronic urticaria (CU) gathers chronic spontaneous urticaria (CSU) and inducible urticaria (IU), and excludes pseudourticarial rashes with more than 24h-lasting rash or more than 72h-lasting angiœdema. Activity and psychosocial impact of the disease must be measured with validated scores such as Urticaria and Angioedema Activity Scores, Urticaria Control Test, CU-Q2OL, AE-QOL. Although an allergic cause is generaly absent in CU, pathomecanisms remain elusive even since the well-known role of mast cell degranulation and the presence of autoantibodies anti-FcRεI or anti-IgE. Coagulation pathways may be involved, at least as an amplifying phenomenon. Mean duration of CU is 1 to 4 years, but many patients still have symptoms after 10 years, some predictive factors being known as severity, angioedema, a positive autologous serum test, inducible urticaria. Recommended routine diagnosic tests are validated provocation tests for IU (and cryoproteins for cold urticaria), blood cell count and CRP for CSU, since a thorough history and a normal detailed physical examination should avoid unnecessary tests. Management of CU has been improved by the off-label use of increased dosages of second generation anti- H1 antihistamines, but a subsequent therapeutic intensification may be necessary in some cases. Educational program may prevent this intensification. Independent studies evaluating available molecules are needed, along with more fundamental research studies.

Abstract
Patients with urticaria suffer itch, swellings, fatigue caused by sleep disturbance and the side effects of medication, and disruption of many facets of their lives. Much progress has been made in formally evaluating the degree of quality-of-life (QoL) impairment suffered by patients with urticaria. This review focuses on QoL in chronic urticaria (>6 weeks duration) and examines QoL measures, including the chronic urticaria-quality of life questionnaire (CU-Q2oL). Patients with urticaria have difficulty identifying and coping with their emotions. The psychiatric comorbidity and the financial burden on the patient and society because of chronic urticaria, is also examined.

Abstract
Urticaria and angioedema are common disorders that can severely impair the quality of a patient's life and can be extremely difficult to treat. Symptoms can persist for years to decades. The causes of urticaria and angioedema are varied and may be immunologic, nonimmunologic, or idiopathic. This article reviews the literature and provides primary care physicians with up-to-date information of the epidemiology, basic pathophysiology, diagnosis, and management of this common and often debilitating condition. Additionally, clinical manifestations of acute and chronic urticaria, hereditary and acquired angioedema, as well as the physical urticarias will be discussed.

Abstract
BACKGROUND Pressure urticaria as a subform of physical urticaria is rare and treatment is often difficult. Established therapeutic regimes include antihistamines (generally exceeding approved dosages in order to achieve a therapeutic benefit) or antihistamines combined with montelukast. Complete relief of symptoms is difficult. PATIENTS AND METHODS We used dapsone as an early therapeutic alternative in the event of treatment failure and established a standardized therapeutic regime at our clinic. We surveyed 31 patients retrospectively who had received dapsone between 2003-2009. RESULTS In 74 % of patients in whom symptoms persisted despite established therapies, the results of treatment with dapsone were good or very good. Longer-term pressure urticaria and the co-existence of a chronic spontaneous urticaria were associated with a smaller benefit (p<0.05). No significant effects were found related to age, gender, duration of therapy, side-effects, or Met-Hb elevation (a tendency toward a decreased benefit was associated with middle-age, male sex, shorter duration of therapy, observed side-effects, and Met-Hb elevation). CONCLUSIONS Therapy is well tolerated and results in a good therapeutic benefit which lasts after termination of therapy. With adequate monitoring, the use of dapsone in patients with pressure urticaria has such a good risk-benefit ratio that we support early treatment initiation.

Abstract
Chronic urticaria (CU) is one of the most frequent diseases in the field of dermatology. Recent studies have shown a point prevalence between 0.5 and 1% in the total population with a predominance of females. In general, all age groups and all classes of the population can be affected. An incidence peak has been found in the third and fourth decades. According to the current guidelines, CU is characterized by the spontaneous occurrence of wheals and/or angioedema for more than 6 weeks. However, epidemiological studies have revealed that the majority of patients suffer for several months, or frequently years. Disease duration is likely to be longer in case of angioedema, a combination with physical urticaria, positivity in the autologous serum skin test (autoreactivity) and a high disease severity. Studies on the impairment of quality of life have been shown that many CU patients suffer as strong from their disease as patients with coronary artery disease. Apart from pure physical symptoms, patients experience restrictions in daily life activities and social life. In addition, sleep disturbances are common and CU patients frequently exhibit psychiatric comorbidities. To avoid frustration in care, it is important to perceive all different dimensions of CU that impact the patient's life and to take the patients and their disease seriously. The aim of therapy should be to obtain total symptom control.

Abstract
BACKGROUND Physical urticarias (PU) are an urticarial response to different specific physical stimuli. PU can occur concurrently with chronic spontaneous urticaria or another type of PU. OBJECTIVE We aimed to study the prevalence, type, clinical data and natural course of each type of PU and other inducible urticarias and also the prognostic factors for remission of patients visiting a tertiary referral hospital. METHOD We performed a retrospective study of 1200 chronic urticaria patients who visited our Urticaria Clinic during a period of 5 years. RESULTS Of the 1200 chronic urticaria patients, 86 (7.2%) were diagnosed as PU and other inducible urticarias. The most common type of PU was symptomatic dermographism (n = 35, 40.7%) followed by cold urticaria (n = 20, 23.3%) and delayed pressure urticaria (n = 11, 12.8%), respectively. Twelve patients (13.9%) had associated chronic spontaneous urticaria. None of the cases had multiple types of PU. Erythrocyte sedimentary rate elevation was the most common abnormal laboratory result. Nevertheless, only 4.6% declared a related infection. For each type, the median time after onset before 50% remission showed that cholinergic urticaria took the shortest course (34 months) and delayed pressure urticaria took the longest period (110 months). After 1 year and 5 years from the onset of symptoms, 13% and 50% of PU patients were free of symptoms, respectively. CONCLUSION This study emphasized the variety of PU, other inducible urticarias and natural courses based on tertiary hospital care. PU and other inducible urticarias have tendency to have a longer course than chronic spontaneous urticaria.

Abstract
The recommendations for the definition and diagnosis presented in this position paper are the result of a panel consensus meeting held in December 2008 in Berlin. This consensus meeting was a joint initiative of EAACI (European Academy of Allergology and Clinical Immunology) Dermatology Section, the EU-funded network of excellence, GA(2)LEN (Global Allergy and Asthma European Network), the EDF (European Dermatology Forum) and UNEV (urticaria network e.V.). The aim of these recommendations is to improve the diagnosis and management of patients with physical urticaria or cholinergic urticaria and to promote research and a better understanding of these diseases. Our recommendations used the paper produced by a 1996 expert meeting (1) and they acknowledge the latest changes in our understanding of physical urticarias and cholinergic urticaria as well as the recent development of novel diagnostic tools. In addition, this consensus paper highlights areas of need for further research.

Abstract
BACKGROUND Chronic urticaria (CU) is a common skin disorder characterized by spontaneous outbreaks of itchy weals and/or angio-oedema over a period of 6 weeks or longer. Very little is known about the health behaviour, symptom patterns or unmet treatment needs of patients with CU. OBJECTIVES To determine how patients with CU manage their condition, when and where their symptom outbreaks occur and what their greatest unmet treatment needs are. METHODS An internet survey was conducted with 321 randomly selected, representative adults in Germany and France diagnosed with CU. The survey covered patient health behaviour, when and where symptoms occur and which effects of CU remain unaddressed. RESULTS The survey found that 78% of the respondents were taking prescription or over-the-counter medication, yet only 33% of those taking medication did so preventively always or often. For 58% of respondents, CU outbreaks lasted 6-10 weeks, while 12% of patients had CU continuously for 52 weeks year(-1). The body parts most frequently reported as most affected by CU were the arms (55% of women and 57% of men; not significant) and the legs (42% of women and 32% of men; P = 0.043). More respondents were bothered by symptoms in the evening (34%) than during the night (23%), morning (23%) or afternoon (20%), and the mode of the frequency for sleep being affected was three nights per week. Itching and physical discomfort remained inadequately addressed for 68% of the respondents, and sleep disturbances from CU remained inadequately addressed for 48% of respondents. CONCLUSIONS A better understanding of health behaviour, symptom pattern and unmet needs of patients with CU will enable physicians and patients to manage this disabling condition more effectively.

Abstract
OBJECTIVES To review diseases that can present with cutaneous signs and symptoms that mimic those observed in chronic urticaria and to discuss the workup necessary to distinguish these diseases from chronic urticaria. DATA SOURCES We performed a PubMed search using the following keywords: urticaria, cryopyrin, Sweet syndrome, subacute cutaneous lupus, urticarial vasculitis, urticaria pigmentosa, angioedema, fixed drug eruption, bullous pemphigoid, and reticular erythematous mucinosis. Appropriate chapters in general dermatology textbooks were also reviewed. STUDY SELECTION Articles that related to disease states, which present with persistent urticarial lesions, were catalogued for use in this review. RESULTS Besides acute, chronic, and physical urticarias, there are 2 categories of diseases that have urticarial lesions. The first group includes those in which the skin lesions are almost indistinguishable from those seen in patients with chronic idiopathic urticaria. Thus, the diagnosis relies on a careful history and physical examination, and in some cases laboratory studies are required. The second group are ones that have skin lesions that at one point in their development have an urticaria-like appearance or on rare occasion may have such lesions. These latter diseases are numerous, and we have tried to highlight the ones that most mimic chronic idiopathic urticaria or are more common. CONCLUSIONS A working knowledge of the diseases that can present with urticarial lesions is essential to accurately diagnose and effectively treat these symptomatic and sometimes serious conditions.

Abstract
BACKGROUND Delayed pressure urticaria (DPU) comes under the heading of physical urticaria. Characteristically itchy, tender or painful weals occur at sites of local pressure including the waistband, soles of the feet and palms of the hands. Lesion onset is typically 3-12 h after the application of pressure, and lesions may persist for more than 24 h. The treatment of DPU is often unsatisfactory. OBJECTIVES To determine the efficacy of desloratadine and montelukast in the treatment of DPU. METHODS The study was conducted in 36 subjects affected by DPU. A challenge test with a dermographometer was administered to confirm the diagnosis. After diagnosis, patients were randomized to receive the following treatment once daily for 2 weeks: (i) oral desloratadine 5 mg plus oral placebo; (ii) oral desloratadine 5 mg plus montelukast 10 mg; and (iii) oral placebo alone. RESULTS At rechallenge, patients from the treatment groups (desloratadine plus montelukast group and desloratadine alone group) demonstrated a significant reduction in mean diameter of papules after 70 s of pressure compared with the placebo group (P < 0.05). Moreover, patients treated with desloratadine plus montelukast showed a significant reduction in mean diameter of papules at 70 s of pressure compared with those treated with desloratadine alone (P < 0.05). In addition, the combination was effective in improving clinical parameters (erythema, oedema and pruritus, and number of separate urticarial episodes). CONCLUSIONS This study has demonstrated that both desloratadine alone and desloratadine plus montelukast administered once daily yield improvements with respect to the baseline assessment, regarding the suppression of the dermographometer challenge test papule and clinical improvement of urticaria. However, the combination of desloratadine and montelukast was shown to be more efficacious and may therefore be proposed in patients with DPU, in order to avoid corticosteroid therapy.

Abstract
BACKGROUND Urticaria is a clinical reaction pattern triggered by many factors causing liberation of vasoactive substances such as histamine, prostaglandins and kinins. It presents as transient itching wheals which are either limited to the local stimulus area or more widespread. Urticaria is classified according to its duration into acute (duration > or = 6 weeks) and chronic (duration 6 weeks) forms. Various clinical investigations may be initiated to diagnose the cause. This study critically evaluates the relevance of frequently performed laboratory investigations and searches for infectious foci, as well as the results of physical provocation testing and oral provocation with food additives. PATIENTS AND METHODS The laboratory and clinical data of 339 patients who had been treated for urticaria at the Christian-Albrechts-University in Kiel over a period of four years were collected in a data entry form and statistically evaluated. Nominal values were analyzed by their relative and absolute quantities, quantitative parameters with the help of statistical data such as minimum, maximum, median and 25th and 75th percentiles. RESULTS Chronic recurrent urticaria was most common, accounting for 52% of cases. Women were affected 1.8 times more often than men. One-third of the patients also had angioedema. The medians of all laboratory parameters evaluated were within normal values. Only rarely were elevated antinuclear antibody titers, abnormal thyroid function tests or active infections such as hepatitis B or borreliosis detected. The search for infectious foci identified tonsillitis or sinusitis in almost 50% of analyzed patients. Positive reactions to physical testing occurred in 30% of patients and in 11% to oral provocation with various food additives. CONCLUSIONS This study of a large patient group stresses the relevance of individually-tailored evaluations in patients affected with urticaria rather than an expensive initial broad diagnostic testing. More specific searches should be based on individual clues.

Abstract
BACKGROUND Dermographism or 'simple' dermographism, which has been noted in about 1.5% to 5% of healthy individuals, is regarded as a normal physiological phenomenon. However, in symptomatic dermographism (SD), even light pressure or rubbing from clothes may provoke widespread weal-and-flare reactions with itching and burning. It is one of the dermatologic diseases that negatively impacts quality of life. OBJECTIVE We aimed to reveal triggering factors and/or associated clinical conditions in patients with SD. METHODS Forty patients (28 women and 12 men) with SD whose ages varied between 7 and 65 (30.3 +/- 10.7) participated in the study. Patients having chronic idiopathic urticaria, other types of physical urticaria and cutaneous/systemic mastocytosis were excluded. The diagnosis of SD was confirmed by stroking the skin of the back with a tongue blade. This procedure elicited within minutes a linear weal with a flare and severe itching. In light of the history, physical examination, skin prick test (SPT) with aeroallergens and laboratory results, a possible relationship of certain triggering factors and/or associated diseases (psychic factors, atopy, thyroid diseases, diabetes, menopause, infectious, systemic or malignant diseases, history of scabies, and history of drug reaction) to SD were investigated. RESULTS The duration of SD varied between 10 days and 10 years (mean: 20.8 months). Psychic factors were found to play the initial triggering role in 12 patients (30%). Five patients (12.50%) were atopic, and they had SPT reactivity to house dust mites. Three female patients (7.50%) defined that their complaints began following drug-induced urticarial rash. Two patients (5%) had hyperthyroidism, and one of the patients with SD of 1-month duration had type-II diabetes mellitus. A female patient defined that her complaints began during the onset of menopausal period. SD was observed with scabies in one patient; and after poststreptococcal glomerulonephritis in a 7-year-old girl. No autoimmune, malignant or other systemic diseases were found in patients with SD. CONCLUSIONS Contrary to commonly held opinion, SD may be associated with some diseases and/or triggered by some conditions. In this study, a close temporal relationship between the appearance of SD and psychic factors, drug reactions and scabies was documented. The relation between SD and atopy, hyperthyroidism, diabetes mellitus, menopause and glomerulonephritis seemed unclear.

Abstract
Bullous delayed pressure urticaria (DPU) is a rare variant of DPU. Treatment of DPU is difficult and the underlying pathogenic mechanism of DPU remains elusive. We report a 72-year-old man with DPU and associated chronic urticaria as well as delayed urticarial dermographism. Pressure challenge gave rise to a deep weal covered by multiple vesicles and bullae after 24 h. Histological examination of a skin biopsy specimen obtained 24 h after pressure challenge demonstrated intraepidermal bullae filled with eosinophils accompanied by a dense, predominantly eosinophilic infiltrate in the dermis. Whereas the numbers and morphology of mast cells were unaltered, the extracellular deposition of eosinophil cationic protein revealed evidence for eosinophil activation. Concomitantly, both CD4+ and CD8+ T lymphocytes were present in the infiltrate and expressed interleukin 5. As bullous DPU may represent the maximal variant of DPU, the investigation of the cellular infiltrate and the chemokines/cytokines released may reveal potential pathogenic mechanisms. A possible effector role of eosinophilic granulocytes, T-cell subsets and mast cells is discussed.

Abstract
BACKGROUND Despite the disabling nature of chronic urticaria (CU), little is known about the disease's duration or the efficacy of adopting aggressive therapeutic regimens such as cyclosporine A. OBJECTIVES The aim of this study was to evaluate whether parameters such as angioedema, autologous serum test, anti-thyroid antibodies, and total IgE could predict both CU duration and severity. PATIENTS AND METHODS One hundred and thirty-nine patients suffering from CU were prospectively followed over a 5-year period for disease duration, severity and the presence of angioedema. Also investigated was the association between these clinical parameters and the subsequent detection of autologous serum test, anti-thyroid antibodies, and total IgE. RESULTS CU lasted over 1 year in more than 70% of cases and in 14% it still existed after 5 years. Angioedema co-existed or appeared during the course of CU in 40% of patients and was associated with disease duration. Autologous serum test and anti-thyroid antibodies were found positive in 28 and 12% of patients, respectively, compared to none of normal individuals, P = 0.001. CU duration was associated with the presence of both autologous serum test and anti-thyroid antibodies; however, autologous serum test and not anti-thyroid antibodies was found in association with CU severity. CONCLUSION We demonstrate for the first time that CU duration is associated with clinical parameters such as severity and angioedema, and with laboratory parameters such as autologous serum test and anti-thyroid antibodies. The ability to predict CU duration may facilitate decisions regarding the possible early initiation of cyclosporine A as a means by which to reduce disease severity and duration.

Abstract
Delayed pressure urticaria is a mechanical urticaria in which pressure causes whealing. Delayed cutaneous erythema and edema occur in association with marked subcutaneous swelling after the application of a sustained pressure stimulus to the skin. The earliest reports and theories of the pathogenesis of delayed pressure urticaria are summarized. Detailed attention is given to making the diagnosis by taking a history and provoking the lesions. The clinical features and natural history are considered. The effects of the disorder on quality of life are delineated, and management strategies are suggested.

Abstract
Urticaria has diverse clinical presentations and causes. The implication of classifying urticaria primarily by clinical presentation rather than aetiology is that management can be focused on specific clinical problems without extensive investigations. Management pathways may involve nonpharmacological measures and drug interventions, which can be grouped into first-, second- and third-line therapies. Stronger, but potentially more risky, second- and third-line approaches may be justified for patients who do not respond to first-line therapy with antihistamines even though it may not be possible to define a specific aetiology, such as autoimmune urticaria, with confidence.

Abstract
Urticaria is defined by weals (hives), with or without angioedema, that appear and peak in minutes to hours, usually disappear within 24 h, and are accompanied by pruritus that worsens during the night. Urticaria is caused by cutaneous mast cell degranulation, attributed to immunological, nonimmunological, and idiopathic causes. Chronic idiopathic urticaria (CIU) is the diagnosis when the pathophysiological mechanism of persistent urticaria remains unclear; up to half of patients with CIU have functional autoantibodies directed against the high-affinity receptor for IgE (FcepsilonRI) or against IgE itself, which appear to induce mast cell degranulation. Systemic histamine H1-receptor antagonists, such as desloratadine, are central to the management of CIU. The efficacy and safety of desloratadine, 5 mg once daily, was studied in a double-blind, randomized, placebo-controlled, multicentre trial that included 190 patients, ages 12 and above, with at least a 6-week history of CIU and experiencing a flare of at least moderate severity. Desloratadine was superior to placebo in controlling pruritus and total symptoms after the first dose, and its superiority was maintained throughout the full 6 weeks of the study. Measures of sleep, daily activity, therapeutic response, and global CIU status were also significantly improved with desloratadine after the first dose and maintained throughout the study.

Abstract
Atopic diseases such as asthma, rhinitis, eczema and food allergies have increased in most industrialised countries of the world during the last 20 years. The reasons for this increase are not known and different hypotheses have been assessed including increased exposure to sensitising allergens or decreased stimulation of the immune system during critical periods of development. In allergic diseases there is a polarisation of the Th2 response and an increase in the production of type 2 cytokines which are involved in the production of immunoglobulin E and the development of mast cells, basophils and eosinophils leading to inflammation and disease. The effector phase of atopy is initiated by interaction with Fc epsilon RI expressed on effector cells such as mast cells and basophils but also found on an ever increasing list of cells. Binding of a polyvalent allergen to the variable part of IgE leads to a cross-link of the receptor that triggers the cell to release histamine and pharmacological mediators of the symptomatic allergic response. Cross-linking of Fc epsilon RI by autoantibodies against the alpha-chain of the Fc epsilon RI, causing subsequent histamine release is thought to be involved in the pathogenesis of other diseases such as chronic idiopathic urticaria (CIU). To date, most therapeutic strategies are aimed at inhibiting and controlling components of the inflammatory response. Recently, new treatment strategies have emerged that focus on the development of preventive and even curative treatments. The most promising therapeutic approaches are aimed at inhibiting the IgE-Fc epsilon RI interaction with the use of non-anaphylactogenic anti-IgE or anti-Fc epsilon RIalpha autoantibodies. Clinical trials in humans using an humanised anti-IgE antibody showed that this antibody was well tolerated and reduced both symptoms and use of medication in asthma and allergic rhinitis. Thus interruption of the atopic cascade at the level of the IgE-Fc epsilon RI interaction with the use of non-anaphylactogenic antibodies is effective and represents an attractive therapy for the treatment of atopic disease.

Abstract
Urticaria is a common disorder affecting one-fifth of the world's population. The pathophysiology is characterized by an increased propensity for mast cell degranulation with the release of potent mediators into the dermal and subdermal tissues with resulting vasoactive, chemotactic, and inflammatory effects. The final clinical manifestation of the typical urticarial lesion is the effect of several diverse effects and causes. The general classification is acute, chronic, and physical urticaria. In general, allergenic triggers can be identified in between 60-80% of acute urticarias. Physical urticarias are characterized by the onset after the specific inciting stimulus, which can reproduce the characteristic lesion which is usually of shorter duration (with the exception of delayed pressure urticaria). Chronic idiopathic urticaria is associated with thyroid autoimmunity and, more recently, anti-mast cell receptor antibodies. An extensive work-up is usually not indicated or helpful in identifying a cause. Food or other allergens are rare causes of this type of presentation. The evaluation and work-up is dependent on clues identified by history. The treatment is removal of specific and non-specific triggers and the use of symptomatic medications generally attenuating the mediator effects.

Abstract
UNLABELLED Chronic urticaria has a spectrum of clinical presentations and causes. About 50% of patients with "idiopathic" disease have histamine-releasing autoantibodies in their blood. The term autoimmune urticaria is increasingly being accepted for this subgroup of patients, in whom immunosuppressive therapies may be appropriate if conventional approaches to management are unsuccessful. This article reviews the classification, causes, and management of chronic urticaria in light of recent advances in the understanding of its etiology. LEARNING OBJECTIVE At the conclusion of this learning activity, participants should have up-to-date knowledge of the classification, assessment, and management of chronic urticaria and understand where the concept of autoimmune urticaria fits into existing frameworks.

Abstract
Histamine-releasing antibodies that act against the epitope of the alpha chain of Fc(epsilon)RI (anti-Fc(epsilon)RI(alpha) antibody) that may affect pathogenesis in serum of patients with chronic urticaria. We assessed the capability of anti-Fc(epsilon)RI(alpha) antibody in sera from patients with chronic urticaria to release histamine and cytokines, and to induce the expression of endothelial cell adhesion molecules. We also assessed the release of inflammatory mediators from cultured foreskin mast cells, and expression of endothelial cell adhesion molecules on human dermal microvascular endothelial cells. Cells were pretreated with mast cell-conditioned media: culture media of mast cells treated with sera from chronic urticaria patients containing anti-Fc(epsilon)RI(alpha) antibody. Histamine release from human foreskin mast cells challenged with sera, increased after both 20 min and 16 h intervals. Leukotriene D4 release also increased at both 20 min and 16 h. Tumor necrosis factor-alpha increased significantly in foreskin mast cell culture challenged with sera of chronic urticaria patients. After the stimulation of human dermal microvascular endothelial cells with the conditioned media, the expression of intercellular cell adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin increased significantly. Treatment of the conditioned media with anti-tumor necrosis factor-alpha monoclonal antibody partially inhibited the expression of intercellular cell adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin. The data suggest that sera from patients with chronic urticaria containing anti-Fc(epsilon)RI(alpha) antibody release mediators and tumor necrosis factor-alpha by activating human foreskin mast cells. This release can play a pathogenic role in chronic urticaria by activating endothelial cells, in part due to the actions of tumor necrosis factor-alpha from mast cells.

Abstract
Delayed pressure urticaria is a physical urticaria where erythematous, often painful swellings occur at sites of sustained pressure on the skin, after a delay of several hours. If sought, it is present in up to 40% of patients with ordinary chronic "idiopathic urticaria" to a varying degree. Compared with other urticarias, the pressure-induced lesions impair the quality of life of patients most severely. The pathogenesis is not well characterized, but whealing is dependent on mast cell activation, with the histology of lesions also showing a deep dermal inflammatory infiltrate of neutrophils and eosinophils, without vasculitis. Treatment of delayed pressure is generally unsatisfactory, and is often resistant to antihistamine and a range of anti-inflammatory medication. Oral steroids, although the most effective therapy, are unsuitable for long-term use. Delayed pressure urticaria may persist for many years, and improved or novel methods of management are under investigation.
