Urticaria is a frequent, mast cell-driven disease, presenting with wheals, angioedema, or both. The life-time prevalence for acute urticaria is approximately 20%. Chronic spontaneous urticaria and other chronic forms of urticaria do not only cause a decrease in quality of life, but also affect performance at work and school and, as such, are members of the group of severe allergic diseases. This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors and pathomechanisms. In addition, it outlines evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS).

Abstract
OBJECTIVE This real-life, global study aimed to investigate current views of and clinical practice in the management of COPD and its exacerbations, among clinicians from both the primary and secondary care settings. METHODOLOGY We devised an online questionnaire about COPD management and invited 13,613 general practitioners (GPs) and respiratory specialists to respond. Participating clinicians, recruited from an established research panel, treated a minimum of 10 (GPs) or 20 (respiratory specialists) patients with COPD per month. Completed responses were collected from 1400 clinicians from 14 countries. RESULTS A third of GPs and respiratory specialists reported that the main goal of COPD management was to improve patients' quality of life; only 14% of GPs thought that the prevention of exacerbations was a priority. The study showed a strong preference for inhaled corticosteroids in combination with other treatments, rather than as sole therapy, in line with global guidelines. Fewer GPs than respiratory specialists routinely recommended anticholinergics, pulmonary rehabilitation or oxygen therapy. Clinicians reported that 55% (GPs) and 57% (respiratory specialists) of their COPD patients had experienced an exacerbation in the previous 12 months. Although higher than those reported in clinical trials, these rates were lower than patients' own estimates from a corresponding patient survey, even in mild COPD patients (62%; 80% in severe patients). Despite this, 74% of GPs and 67% of respiratory physicians reported satisfaction with therapies to prevent exacerbations. CONCLUSIONS This global survey revealed that clinicians' main goal when managing COPD was to improve the lives of their patients, and that few viewed reducing exacerbations as a priority. Despite a relatively high level of adherence to treatment recommendations, it appears that clinicians, particularly GPs, underestimate the frequency and impact of exacerbations. These results suggest a need to raise awareness of exacerbations among both GPs and respiratory specialists.

Abstract
PURPOSE Eosinophilic cystitis is a rarely seen condition in the pediatric population with indistinct symptomatology and non-standardized treatment protocols. We review our experience of treating patients with this condition. MATERIALS AND METHODS We retrospectively reviewed the records of four patients from a single institution who have been diagnosed and treated for eosinophilic cystitis. In addition, the literature was reviewed for cases of pediatric eosinophilic cystitis. Our patients were added and compared to this cohort. RESULTS Our patients included 3 females and 1 male who range in age from 5 days to 18 years (5 days, 1 month, 7 years, 18 years). Both of the infants presented with a suprapubic mass and bilateral hydroureteronephrosis. The two older patients both had dysuria while the 18 yo also complained of fatigue, flank pain, and hematuria. Only 2 of the 4 patients were found to have significant peripheral eosinophilia and only one patient had eosinophiluria. All of the patients were diagnosed via cystourethroscopy with biopsy. Treatment in each case consisted of a combination of steroids, antihistamines, and antibiotics. CONCLUSIONS The presentation of eosinophilic cystitis is varied and diagnosis requires a high index of suspicion. Cystourethroscopy with biopsy is essential to establish the diagnosis as there is no typical appearance of the lesions or presenting signs/symptoms. Most cases of eosinophilic cystitis are responsive to medical therapy although in some cases recurrence may be noted.

Abstract
PURPOSE To compare the inhibitory effects of dexamethasone and heparin on the infiltration of mast cells in the conjunctiva by using a mouse allergic conjunctivitis model. METHODS 24 Balb/c mice were divided into four groups: allergy group (positive control), dexamethasone group, heparin group, and negative control group, as groups 1, 2, 3, and 4, respectively. Each group comprised 6 mice, and experimental allergic conjunctivitis was developed in groups 1, 2, and 3. The mice in group 2 were treated with topical 0.1% dexamethasone eye ointment, and the mice in group 3 were treated topically with 5,000 IU/ml standard heparin. Both dexamethasone and heparin were instilled once a day for 4 days. Hanks' balanced salt solution was dropped into both eyes of the mice in group 4 instead of dexamethasone or heparin. Eyeballs and eyelids were removed from the mice in all groups while one eye of each animal was used for histopathological, the other for molecular biological examination. RESULTS Mast cells, infiltrating the subconjunctival tissue, were significantly lower in group 2 (p < 0.0001), group 3 (p < 0.0001) and group 4 (p < 0.0001) when compared to group 1. CONCLUSIONS Topical heparin could be a viable option in treating IgE-induced allergic eye disease since it is found to be as effective as topical dexamethasone in experimental acute allergic eye disease.

In these calculations, the pre-equilibrium and equilibrium effects have been investigated. The pre-equilibrium calculations involve the geometry dependent hybrid model and the cascade exciton model. The full exciton model has also been used to investigate the pre-equilibrium direct effects. Equilibrium effects are calculated according to the Weisskopf–Ewing model. The calculated results are compared with the experimental data taken from the literature.

Abstract
Morphological features of coronary arteries and incidental lesions are reported from hearts in five species of sharks, the shortfin mako shark, Isurus oxyrhinchus Rafinesque, thresher shark Alopias vulpinus (Bonaterre), blue shark, Prionace glauca L., the smooth dogfish, Mustelus canis (Mitchill), and spiny dogfish, Squalus acanthias L. Sharks were collected from the northwestern Atlantic between June and August from 1996 to 2010. They were necropsied dockside and the hearts were preserved in buffered formalin. Routine sections including ventricle/conus arteriosus and the atrio-ventricular junctions were embedded in paraffin, stained with common histological and immunohistochemical methods and examined by brightfield microscopy. Myointimal hyperplasia, medial myo-myxomatous hyperplasia and bifurcation pads were observed commonly, and medial muscle reorientation and epicardial myeloid tissues were rare. All the above features differed in severity, prevalence and distribution depending on anatomical site and shark species/size. Morphometric analysis indicated that myomyxomatous hyperplasia is associated with luminal narrowing of blood vessels. As suggested previously, the described morphological features are most likely physiological responses to blood flow characteristics. Vascular and cardiac lesions were uncommon and included, granulomatous proliferative epicarditis with fibroepitheliomas, myxomatous epicardial expansions, medial arterial vacuolation, myocardial fibrosis, acute ventricular emboli and parasitic granulomas. The lesions of embolism, proliferative and granulomatous epicarditis and myocardial fibrosis were in all sharks associated with capture events including retained fishing hooks. The significance and aetiopathogenesis of medial vacuolation and epicardial myxomatous expansions remains unclear.

Abstract
ABSTRACTWe present a femtosecond pump-probe ellipsometer operating over a spectral range of 1.4 – 1.7 eV with a ∼50fs time resolution. The calibration and preliminary findings of the setup are discussed. We tested the apparatus on bulk crystalline silicon (not shown here) and on silicon nanocrystals embedded in an amorphous silicon phase. The ellipsometric angles (ψ, Δ) were determined as a function of time and wavelength. The results suggest that a simple Drude model of free carrier absorption is not sufficient to explain the findings.

Abstract
Bradykinin has been implicated to contribute to allergic inflammation and the pathogenesis of allergic conditions. It binds to endothelial B(1) and B(2) receptors and exerts potent pharmacological and physiological effects, notably, decreased blood pressure, increased vascular permeability and the promotion of classical symptoms of inflammation such as vasodilation, hyperthermia, oedema and pain. Towards potential clinical benefit, bradykinin has also been shown to exert potent antithrombogenic, antiproliferative and antifibrogenic effects. The development of pharmacologically active substances, such as bradykinin receptor blockers, opens up new therapeutic options that require further research into bradykinin. This review presents current understanding surrounding the role of bradykinin in nonallergic angioedema and other conditions seen by allergists and emergency physicians, and its potential role as a therapeutic target.

Abstract
PURPOSE OF THE STUDY Avulsion fractures of the intercondylar eminence (ICE) of the tibia have become increasingly frequent in older school age. Due to recent advances in arthroscopic techniques, it is now possible to treat them by minimally invasive methods. This retrospective study presents evaluation of clinical outcomes of an arthroscopic technique using crossed K-wires. MATERIAL Thirty-five patients with ICE avulsion fracture, 17 girls and 18 boys at an average age of 13 years (7-18), were included in this study. All were indicated for surgical treatment on the basis of radiographic evidence of McKeever type II and III fractures. METHODS The technique of arthroscopic reduction and fixation with crossed K-wires was used. The clinical evaluation of knee stability (anterior drawer test and Lachmann s-test) was made by one clinician. The modified Tegner-Lysholm score was assessed. RESULTS Of the 35 patients, 26 (74%) had minimal knee instability (anterior drawer up to 5 mm), two patients were primarily converted to open reduction with good results, and three (8.5%) experienced temporary knee instability (anterior drawer of 5-10 mm) that resolved spontaneously within 24 months of surgery. Four patients (11.5%) had symptoms of persistent residual instability (anterior drawer more than 10 mm) and were indicated for anterior cruciate ligament reconstruction at a later stage. The average Tegner-Lysholm scores were 86.3/100 and 98.6/100 at 6 and 24 months, respectively. DISCUSSION At the present time at our department, McKeever type II and III avulsion fractures of the intercondylar eminence are indicated for minimally invasive surgical treatment. By exact reduction it is possible to decrease the risk of post-operative knee instability. The current trend is the use of arthroscopy-assisted minimally invasive techniques such as the method of K-wire fixation described here. CONCLUSIONS Arthroscopic surgery for ICE avulsion fractures shows good results, is associated with low post-operative risks, is minimally invasive and easy to reproduce. It can be recommended as the method of choice for treating ICE avulsion injury in children.

Abstract
BACKGROUND Anaphylaxis is often managed inadequately. We used findings from a systematic review of gaps in anaphylaxis management to develop evidence-based recommendations for gaps rated as clinically important by a panel of Canadian allergy experts. METHODS The nominal group technique (NGT) consensus methodology was used to develop evidence-based recommendations for the management of anaphylaxis in primary care. Physician-specific gaps from our systematic review were prioritized by consensus meeting participants in two rounds, which involved the rating, discussion, and re-rating of gaps. Using current anaphylaxis guidelines, recommendations were then developed for each category of gaps that were identified by the panel as clinically important. RESULTS Thirty unique physician gaps from the systematic review were categorized according to gaps of knowledge and anaphylaxis practice behaviors. The panel rated diagnosis of anaphylaxis, and when and how to use epinephrine auto-injectors as clinically important knowledge gaps; and rated infrequent or delayed epinephrine administration, low rate of auto-injector prescription, and infrequent or no referrals to allergy specialists after a reaction as important practice behavior gaps. Evidence from four guidelines was used to support the consensus recommendation statements for three resulting categories of gap themes: anaphylaxis management, epinephrine use, and follow-up care. CONCLUSION We used an NGT consensus methodology to develop an educational resource for primary care physicians and allergists to better understand how to manage patients with anaphylaxis. Next steps include testing our findings against observed data in primary care settings and to develop other strategies or tools to overcome gaps in anaphylaxis management.

Abstract
1. Renin was found in both the mesonephric and metanephric kidneys of the smallest hog fetuses examined. These were from 17 to 24 mm. in length in the case of the former, and 25 to 49 mm. in that of the latter. 2. No evidence was found in either type of kidney of juxtaglomerular cells described by Goormaghtigh as the probable site of renin formation. 3. The renin content in both the mesonephros and the metanephros was found to be independent of its arteriologlomerular component but directly dependent upon the number, size, and functional state of the tubular component. It increased in amount with increasing tubular proliferation during the course of embryonic development, and decreased with the progressive tubular atrophy and degeneration incident thereto. 4. The site of renin formation is discussed.
