Moreover retrospective studies have demonstrated that the duration of. untreated disease directly correlates with the prevalence of esophageal. strictures in a time dependent manner 21 Likewise an association. has been demonstrated in the natural history of Crohn s disease. The classical treatment goals of EoE namely 1 the resolution of clin. ical symptoms and 2 achieving and maintaining disease remission. have been expanded to include 3 the prevention of fibrotic compli. cations such as strictures 4 avoidance of the iatrogenic effects of. medication 5 maintenance of an adequate QoL and 6 the pre. vention of nutritional deficiencies due to dietary treatment. Summary of available alternatives to dietary therapy for EoE. Pharmacological treatment for EoE patients has mainly comprised. the use of several anti inflammatory drugs used in other allergic. disorders The first reported cases of EoE were effectively managed. with systemic steroids which were later replaced by topical steroids. after these were shown to have a similar effectiveness with a lower. rate of side effects First used in pediatric patients 22 topically. administered swallowed fluticasone propionate FP has been shown. to be highly effective in children 23 significantly superior to a. placebo 24 and comparable to oral prednisone 25 1b grade A. Similar results have been documented in adults 26 Viscous. budesonide has also emerged as an alternative treatment for both chil. dren 27 and adults with EoE 28 having been proven safe and effective. 1b grade A Ciclesonide has also recently been added to the pharma. cological armory for treating EoE 29 However given the chronic nature. of EoE sustained treatment with steroids or repeated courses must be. considered even after achieving disease remission Finally azathioprine. 6 mercaptopurine was found to be effective in causing the remission of. symptoms and eosinophilic infiltration for periods of 3 8 years in adults. with steroid dependent EoE and eosinophilic gastroenteritis with. esophageal involvement 30, Other anti allergy drugs such as anti H1 blockers or the mast cell. stabilizer disodium cromoglycate have shown no therapeutic benefit. in patients with EoE 31 Montelukast is likewise not recommended. for the management of EoE 1 as it is unable to maintain remission. achieved with topical steroids 32 4 grade C, Several biological therapies based on monoclonal antibodies have. been assessed in EoE with limited results Thus the anti TNF. infliximab failed to demonstrate any beneficial effects in adult EoE. patients 33 nor did the anti IgE omalizumab lead to clinical im. provement in children 34 However when the anti IL 5 monoclo. 160 Food Allergy M Fern ndez Rivas Section Editor, nal antibodies mepolizumab and reslizumab were analyzed in ran. domized controlled trials in both adult 35 and pediatric 36 37. patients tissue eosinophils were significantly reduced Unfortunate. ly clinical improvement was minimal 1b grade A, Despite the fact that EoE is defined as the persistence of eosinophilic. inflammation after acid suppression proton pump inhibitors PPIs. have been used successfully as a sole therapy for EoE patients 38 39. The anti inflammatory properties of PPIs were recently demonstrated in. vitro after they were able to reduce the gene expression of eotaxin 3 a. key chemo attractant involved in the pathophysiology of the disease in. esophageal cell cultures from EoE patients 40 Until a clearer eluci. dation of the real significance of PPI responsive EoE is developed. consensus guidelines currently consider this disease to be a specific. manifestation of gastroesophageal reflux disease 1. Endoscopic dilation a mechanical procedure with no effect on the. underlying inflammatory process seems to result in at least a short. term improvement of symptoms in the majority of patients ac. cording to a recent meta analysis 41 It has mostly been used in. adult EoE patients who often present esophageal stenosis with a. reduction of esophageal caliber When performed by an experienced. specialist esophageal dilation is a safe procedure 41 However. various risk factors for complications have been identified including. a long evolution of dysphagia high eosinophil density young pa. tient age repeated procedures and luminal narrowing in the upper. and middle esophageal thirds 42 43,Dietary approaches for EoE. Elemental diet in EoE, Since 1995 after an initial report showed that feeding 10 children. exclusively with an amino acid based elemental formula led to. symptom relief and histological normalization of EoE 13 several. studies have reproduced these findings in pediatric series 44 45. 46 In fact results show that more than 90 of patients rapidly. reach peak eosinophil counts G15 hpf with symptomatic improve. ment in 996 of cases 4 grade C Moreover subsequent con. trolled re introduction of solid foods results in recurrence of. gastrointestinal symptoms specific to individual trigger foods. The first report regarding the use of elemental diet to treat adult EoE has. been published only very recently 47 A series of 29 patients were. prospectively recruited and told to avoid any kind of food except an. elemental formula for a four week period Three patients abandoned. the study protocol on the first day and eight more consumed forbidden. solid foods during the first 2 weeks of the study period A pathological. infiltration of 915 eos hpf persisted in only one out of the 18 adults who. completed the study 4 grade C giving a per protocol efficacy of 94 4. which went down to 58 8 when analyzed for intention to treat. Dietary Management of Patients with Eosinophilic Esophagitis Lucendo and Arias 161. A rapid recurrence of eosinophilic inflammation after resuming a. normal diet is the norm in both children and adults therefore ad. ditional dietary strategies should be implemented after elemental. diet induced remission of the disease, Although the efficacy of an elemental diet has proven superior to that. of any other type of dietary intervention in managing EoE several. drawbacks restrict its use in clinical practice including its unpleasant. taste which forces up to 80 of pediatric patients to be fed through. a nasogastric tube 31 its high non adherence rates 48 the many. limitations it places on social activities due to the complete avoid. ance of any kind of table food and its high cost This latter limitation. leads to the additional disadvantage that some insurance plans do. not cover this type of therapy, The only realistic utility of elemental diet in clinical practice is to feed. infants and toddlers among whom the restriction of having no ad. ditional food may be better tolerated and only during the length of. time required for food reintroduction with the goal of identifying. specific dietary triggers,Elimination diets directed by allergy testing. The growing body of evidence showing that exposure to food aller. gens leads to EoE has prompted researchers to attempt to identify. specific food triggers for the disease sometimes using clinical histo. ries which is complicated as patients do not usually associate the. consumption of certain foods with the appearance of symptoms. but most often using skin prick tests SPTs and or atopy patch tests. In 2002 Spergel et al used SPTs and APTs on pediatric EoE patients. for the first time to determine a suitable elimination diet 49 The. avoidance of foods that gave positive skin test results led to histo. logical and clinical resolution in 49 of patients 50 with this. strategy an average of five foods were excluded from each child s diet. 4 grade C The authors adverted on the variable sensitivity and. specificity of these allergy tests with G10 of positive results in both. tests along with their low sensitivity to cow s milk which as noted. below is the most common food trigger for EoE The same authors. have recently evaluated a new strategy consisting of the elimination. from the diet of foods identified through SPT APT in addition to an. empirical elimination diet Combining the two strategies led to in. creases in histological remission rates of up to 77 50. Unfortunately the aforementioned results regarding the histological. remission of EoE have not been reproduced by other research groups. Allergy tests failed to identify food triggers in most patients in several. pediatric 51 52 53 and adult series 47 54 55 56 57. Moreover food specific IgE serum measurements and SPTs were. 162 Food Allergy M Fern ndez Rivas Section Editor, neither sensitive nor specific methods for predicting EoE triggers in. adult patients 57 58, A growing body of evidence points to the involvement of a cell. mediated delayed reaction against foods rather than an IgE me. diated reaction in the pathophysiology of EoE As a result EoE. usually coexists together with other IgE mediated atopic mani. festations in a single patient each of which responds to different. underlying mechanisms thus limiting the clinical utility of IgE. testing for directing dietary interventions in patients with EoE. Indeed because positive results from SPTs serum IgE and ATPs. cannot be used alone to identify food triggers in EoE food re. strictions should not be recommended exclusively based on a. positive result Currently food triggers can only be identified by. documenting disease remission after specific food antigen. avoidance followed by EoE recrudescence upon reintroduction of. the food in question 1 This is the strategy used in the empir. ical elimination diets and food reintroduction protocols discussed. Empirical elimination diets in EoE, In an attempt to overcome the disadvantages of elemental and allergy. testing directed diets in children with EoE Kagalwalla et al explored the. alternative of eliminating the six foods containing those intact food pro. teins most commonly associated with food allergy in children 45 The. original 6 food elimination diet SFED which specifically excluded milk. protein soy egg wheat peanut tree nuts and seafood from the subjects. diets led to significant improvement of both esophageal inflammation. G10 eos hpf and symptoms in 74 of the 35 children treated during a 6. week period, Comparable response rates to those reported in children 46 have. also been documented for SFED in two prospective American and. European series of adult EoE patients 57 58 4 grade C It. should be noted that the original list of foods restricted by. Kagalwalla was broadened to include foods that gave a positive SPT. result 46 59 taking into account geographical food sensiti. zation patterns 58, Most importantly using sequential single food reintroduction re. searchers were able to clearly identify individual food triggers in chil. dren 59 and adults 57 58 by documenting disease recurrence. through repeated endoscopies with biopsies Cow s milk wheat and. eggs in that order have been identified as the major food triggers in all. available studies to date The frequency and involvement of the re. maining triggers varies from one region to another giving rise to the. question of whether empirical exclusion diets should be tailored to each. specific region and based on the staple diets and food sensitization. Dietary Management of Patients with Eosinophilic Esophagitis Lucendo and Arias 163. profiles of where the patient is being treated 58, The sustained efficacy of food trigger avoidance has only been. assessed in two studies 58 60 For a period of up to 3 years every. patient who followed the diet remained asymptomatic with no. pathological eosinophilic inflammation seen in annual endoscopic. examinations Moreover no drug treatment was necessary for pa. tients with sustained remission of EoE 58, Finally allergy tests based on demonstrating an IgE driven hyper. sensitivity showed limited usefulness in identifying EoE triggers in. SFED based studies exhibiting extremely low concordance with the. results of food reintroduction challenges 57 58 59. Empirical elimination of cow s milk, Cow s milk protein has been demonstrated to be the food antigen. most frequently linked to EoE in both pediatric 46 50 59. and adult patients 57 58 identified as an EoE trigger in ap. proximately three out of four subjects, There are an increasing number of reports of patients developing EoE. after milk 61 and egg 62 oral immunotherapy Data on long term. food tolerance induction are still scarce 63 the possibility of a. change in the pattern of the immune response from Th2 to Th1 type. should be taken into account, As a result a recent retrospective study 64 focusing solely on cow s. milk showed significant histological remission of EoE G15 eos hpf. in 65 of children and symptom improvement in all patients after. the elimination of milk from the diet The unexpectedly high efficacy. of this strategy may have been influenced in this study by the in. clusion of patients with a particular allergic background i e a pre. vious IgE mediated cow s milk allergy undergoing desensitization. In conclusion EoE patients with a previous history of Th2 mediated. food allergy and who are undergoing oral desensitization should be. considered for specific single food removal followed by endoscopic. and bioptic monitoring for EoE remission The advantages and. drawbacks of re exposing the patient to allergic reaction including. anaphylaxis in the case of accidental consumption should be care. fully weighed, Food reintroduction and identification of food triggers. Food reintroduction is essential in the dietary management of EoE. and should always be considered after patients on elemental or. elimination diets present normal esophageal biopsies Food rein. troduction has the double aim of selectively identifying foods that. trigger EoE as well as improving patient acceptance of and adherence. to a less restrictive diet,164 Food Allergy M Fern ndez Rivas Section Editor. It is worth noting that one or more independent foods can be re. sponsible for EoE thus while three out of four Northwestern. American pediatric and adult patients exhibited a single food. trigger 57 59 this was documented in only one out of three. adult Spanish patients 58 Although very limited information is. available on this topic following a more varied diet the Mediter. ranean diet as compared to the Northwestern American diet or an. adult s diet compared to a child s may increase the probability of. developing a food allergy manifested as EoE, There are two possible strategies for planning the reintroduction se. quence The first is to begin with foods unlikely to cause EoE e g. vegetables and fruits chicken and beef in order to normalize the. patient s diet as soon as possible 65 The alternative strategy. assessed in SFED based trials consists of first reintroducing wheat. and milk because although they are the most common EoE triggers. if the result is negative their impact in returning patients to a normal. diet is higher 58, After demonstrating EoE triggered by cow s milk the immediate re. introduction of soy may provide patents with an effective milk sub. stitute Due to the common cross reactivity with cow s milk proteins. sheep s and goat s milk derived products mainly cheeses should. also be excluded, How can we succeed in the dietary management of EoE patients. The lack of multicenter randomized comparative studies on the. effectiveness advantages and drawbacks of empirical elimination. diets vs skin allergy testing prevent us from undoubtedly. recommending one dietary option over another However available. evidences show that SFED seems to be the best current dietary ap. proach for treating EoE patients having provided the greater and. more consistent results in different studies and it should be con. sidered for both children and motivated adults Until better and. more accurate food allergy testing capable of identifying specific food. triggers is available or until genetic profiling can accurately predict. individual responses to diet the unreliability of skin allergy testing. limits the use of this method to experienced centers where it has been. proven to be efficient, Food triggers of EoE have repeatedly been demonstrated to be foods. commonly consumed in the standard Western diet including milk. wheat and eggs This begs the question of whether these trigger. foods are the same for other geographical regions for example Asia. where rice and soy are common in the staple diet Consequently. when planning a dietary intervention to manage EoE it should be. taken into account that allergy sensitization patterns depend on an. tigen exposure which varies from one place to another 66 68. Dietary Management of Patients with Eosinophilic Esophagitis Lucendo and Arias 165. As a result it seems reasonable to design food interventions based on. skin allergy testing or empirical elimination according to the staple. diet adapting each strategy to regional consumption habits and al. lergy sensitization patterns, To date there is no definitive data on the specific predictors of. clinical response to dietary intervention in adult EoE indeed neither. symptoms nor endoscopic histopathological background have dif. fered significantly among responders and non responders 58. Moreover extended experience in managing adult EoE with an SFED. was associated with increased response rates pG0 05 57 In the. case of exclusive elimination of cow s milk younger patients and. those with a lower peak eosinophil count exhibited a significantly. increased remission rate 64, The risk of nutritional deficiencies derived from extensive food re. strictions must be adverted especially in pediatric EoE patients The. collaboration of a dietician is strongly recommended for patient and. parent dietary counseling as a specialist can provide useful instruc. tions and guidelines to ensure correct dietary management of the. disease The possibly harmful effects of food restrictions on adult. patients seem to be minimal In any case extended food restrictions. like those imposed in empirical SFEDs should only be used to induce. disease remission over the course of several weeks After that food. reintroduction constitutes an essential part of the dietary manage. ment of EoE patients and should be always considered after normal. esophageal biopsies have been achieved, Long term difficulties in adhering to an elimination diet mostly de. pend on the type and number of food triggers involved in EoE Key. factors for improving adherence include finding appropriate substi. tutes for the eliminated foods and simplifying the food elimination. study protocols Cow s milk based extensively hydrolyzed formulas. have been demonstrated to be well tolerated by most adult patients. with milk triggered EoE 69 Ongoing research on 4 food elimi. nation diets may simplify study protocols and reduce the number of. endoscopies needed, Since repeated endoscopies and biopsies are essential for identifying. EoE food triggers sedation should be guaranteed for these patients. especially since it increases their willingness to undergo repeated. procedures In order to reduce the number of endoscopic exams. needed some authors have performed them after the reintroduction. of two foods but this strategy may lead to potential confusion since. symptoms do not universally reappear quickly in every patient. Unsolved aspects suggestions for further research, It is interesting to note that the various dietary interventions avail. able for EoE patients show relatively similar results with regard to. 166 Food Allergy M Fern ndez Rivas Section Editor, efficacy ranging from 96 to 70 13 32 44 45 46 50 57. 58 We can thus safely assert that in most of patients with EoE the. disease is triggered and maintained exclusively by food with a very. small remainder attributable to airborne allergens. Differences in the efficacy of exclusive feeding with an elemental diet. compared with empirical elimination diets can be explained by al. lergy to those foods that are not restricted from the diet mostly fruits. and vegetables In fact most adult EoE patients exhibit sensitization. to cross reactive panallergen components including profilins 70. and lipid transfer proteins LPT which are mostly found in food of. vegetal origin, Because EoE is a chronic malady foods identified as triggers for. the disease should be avoided indefinitely 1 after that and. even when a sustained drug free response is achievable for most. patients with EoE it is tempting to speculate on the possibility of. inducing food tolerance by progressive EoE trigger reintroduction. Unfortunately the only available study on this topic provided. disappointing results 59 with EoE universally reappearing. after food reintroduction in every child who had been in remis. sion for a period of up to 4 years, The search for noninvasive markers of active esophageal inflam. mation must go on in order to facilitate the use of dietary. therapies for EoE Unfortunately subrogate biochemical markers. including serum levels of eosinophil derived granular proteins. have shown little usefulness in monitoring disease activity 71. However a novel minimally invasive string test was recently. found to accurately reflect mucosal eosinophilic inflammation by. measuring eosinophil derived proteins in luminal secretions 72. Further research is needed to demonstrate the usefulness of this. test in clinical practice, Finally in order to better define novel and targeted dietary based. therapies the many unresolved aspects concerning the immuno. logical and physiopathological mechanisms of EoE must be elu.

Practical problems of mechanics and geometry, such as searching for the shortest distance between straight lines or parameterizing the orbit of a parti-cle, will lead us to the differentiation of vectors and to vector analysis. Vector analysis is a powerful tool to formulate equations of motions of particles

After the players are warm, have one line back-up so everyone is throwing farther than the base path (*note: adjust the distance for younger age groups). Start all the balls with the players lined-up on the foul line.

speech enhancement using spectral subtraction is shown in Fig. 1. It involves windowing, FFT, noise spectrum estima-tion, spectral subtraction, complex spectrum calculation, and resynthesis using IFFT with overlap-add. Windowed frames of the noisy speech signal x(n) are given to a FFT block to find magnitude and phase spectra.
