Treatment of Peritoneal Surface Malignancies by Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Spain: Results of the National Registry of the Spanish Group of Peritoneal Oncologic Surgery (REGECOP).

INTRODUCTION: Treatment of Peritoneal Surface Malignancies (PSM) with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has achieved results never seen before in these patients, which classically have a poor prognosis. The possibility of conducting clinical trials in these diseases is complicated, since some of them are rare, so the analysis of large databases provides very valuable scientific information. The aim of this study is to analyze the global results of the National Registry of the Spanish Group of Peritoneal Oncologic Surgery (REGECOP), whose objective is to register all patients scheduled for HIPEC nationwide. METHODS: This is a retrospective analysis of the data recorded in the REGECOP from 36 Spanish hospitals from 2001 to 2021. There were 4159 surgical interventions in 3980 patients. RESULTS: 66% are women and 34% are men with a median age of 59 years (range 17-86). 41.5% of the patients were treated for Peritoneal Metastases (PM) of colorectal cancer (CRC); 32.4% were women with ovarian cancer (OC) with PM; 12.8% were treated for pseudomyxoma peritonei (PMP); 6.2% had PM from gastric cancer (GC); 4.9% had PM of non-conventional origin; and, finally, 2.1% of cases were patients diagnosed with peritoneal mesothelioma. The median Peritoneal Cancer Index (PCI) was 9 (0-39), and complete cytoreduction was achieved in 81.7% of the procedures. Severe morbidity (Dindo-Clavien grade III-IV) was observed in 17.7% of surgeries, with 2.1% mortality. Median hospital stay was 11 days (0-259). Median overall survival (OS) was 41 months for CRC patients, 55 months for women with OC, was not reached in PMP patients, was 14 months for GC patients, and 66 months in mesothelioma patients. CONCLUSIONS: large databases provide extremely useful data. CRS with HIPEC in referral centers is a safe treatment with encouraging oncologic results in PSM.

Proton Pump Inhibitor Therapy in Pediatric Eosinophilic Esophagitis: Predictive Factors and Long-Term Step-Down Efficacy.

OBJECTIVES: To assess the short- and long-term efficacy of proton pump inhibitor (PPI) therapy for pediatric eosinophilic esophagitis (EoE) in real-world practice with a step-down strategy, and to evaluate factors predictive of PPI responsiveness. METHODS: We collected data regarding the efficacy of PPIs during this cross-sectional analysis of the prospective nationwide RENESE registry. Children with EoE treated with PPI monotherapy were included. Histological remission was defined as a peak eosinophilic count of <15 eosinophils (eos)/high-power field (hpf). Factors associated with PPI responsiveness were identified using multivariate logistic regression analysis. RESULTS: After induction therapy, histological and clinico-histological remission were observed in 51.4% (n = 346) and 46.5% of children, respectively. Normal endoscopic appearance of the esophagus was associated with a higher possibility [odds ratio (OR), 9.20; 95% confidence interval (CI), 2.10-40.16], and fibrostenotic phenotype was associated with a lower possibility (OR, 0.36; 95% CI, 0.18-0.74) of histological remission. Long-term therapy with a step-down strategy effectively maintained histological remission in 68.5% and 85.3% of children at 7 months (n = 108) and 16 months (n = 34), respectively. Complete initial histological remission (≤5 eos/hpf) was associated with a higher possibility of sustained histological remission (OR, 5.08; 95% CI, 1.75-14.68). Adverse events were infrequent and mild. CONCLUSIONS: We confirmed the efficacy of PPIs for a large cohort of children with EoE with sustained histological remission using a step-down strategy. Children with fibrostenotic phenotypes are less likely to respond to induction therapy. Furthermore, patients with complete initial histological remission are more likely to experience long-term histological remission.

Characterization of Eosinophilic Esophagitis From the European Pediatric Eosinophilic Esophagitis Registry (pEEr) of ESPGHAN.

OBJECTIVES: Few pediatric data on phenotypic aspects of eosinophilic esophagitis (EoE) are available. The pEEr registry was developed to prospectively characterize children with EoE from Europe and Israel. METHODS: pEEr is an ongoing prospective registry enrolling children with esophageal eosinophilia (≥15 eos/HPF). Anonymized data were collected from 19 pediatric centers. Data regarding demographics, clinical manifestations, endoscopy, histology, and therapies were collected. RESULTS: A total of 582 subjects (61% male) were analyzed. The median age at diagnosis was 10.5 years [interquartile range (IQR): 5.7-17.7], whereas the age at symptom onset was 9.2 years (IQR: 4.3-16.4), resulting in a median diagnostic delay of 1.2 years (IQR: 0.7-2.3). The diagnostic delay was longer below age <6 years. Shorter diagnostic delays were associated with the presence of food allergy or a family history for EoE. Symptoms varied by age with dysphagia and food impaction more common in adolescents, while vomiting and failure to thrive more common in younger children ( P < 0.001). Among endoscopic findings, esophageal rings were more common in adolescents, whereas exudates were more frequent in younger children( P < 0.001). Patients who responded to proton pump inhibitors (PPIs) were more likely to be older, males, and less often presented severe endoscopic findings. Patients unresponsive to PPIs received topical steroids (40%), elimination diet (41%), or a combined therapy (19%). CONCLUSIONS: EoE findings vary according to age in pediatric EoE. Young children are commonly characterized by non-specific symptoms, atopic dermatitis, food allergy, and inflammatory endoscopic lesions. Adolescents usually have dysphagia or food impaction, fibrostenotic lesions, and a better PPI response.

Systemic steroids have a role in treating esophageal strictures in pediatric eosinophilic esophagitis.

BACKGROUND: The role of systemic steroids in the treatment of esophageal strictures in children with Eosinophilic Esophagitis (EoE) is poorly defined. AIMS: To describe a cohort of children with EoE-associated esophageal strictures responding to systemic steroids. METHODS: Retrospective review of medical records of children with EoE and moderate (<9 mm) to severe (<6 mm) strictures, who responded clinically and endoscopically to systemic steroids. RESULTS: Twenty children (median age 10.6 ±â€¯4.2 years; 17 males) from nine centers in six countries were included in the analysis; 16 had moderate and four, severe strictures; 18 had dysphagia or bolus impaction; median diagnostic delay was 8 months (IQR 3.5-35). Eighteen patients received oral systemic steroids (mean dose 1.4 mg/kg/day) for a median of 4 weeks, while two initially received IV steroids. All patients showed clinical improvement and 15/20 became asymptomatic. Stricture resolution at endoscopy was found in 19/20, while histological resolution of EoE (<15 eos/hpf) in 13/20. Only minor side effects were reported: hyperphagia (10/20); weight gain (5/20); hyperactivity (2/20) and acne (1/20). Esophageal dilation was required in 3/20 patients during a median follow-up of 48.5 months (IQR 26.7-73.2). CONCLUSION: Children with EoE and esophageal strictures, may benefit from the use of a short course of systemic steroids, avoiding mechanical dilation.

COVID-19 Gastrointestinal Manifestations Are Independent Predictors of PICU Admission in Hospitalized Pediatric Patients.

Multicenter study conducted in 15 hospitals including 101 COVID-19 pediatric inpatients aiming to describe associated gastrointestinal (GI) manifestations. GI symptoms were present in 57% and were the first manifestation in 14%. Adjusted by confounding factors, those with GI symptoms had higher risk of pediatric intensive care unit admission. GI symptoms are predictive of severity in COVID-19 children admitted to hospitals.

Normal fecal calprotectin levels in healthy children are higher than in adults and decrease with age.

BACKGROUND/OBJECTIVES: The paediatric reference range of fecal calprotectin (FC) has not been decisively established and previous studies show a wide within-age variability, suggesting that other factors like anthropometric data or type of feeding can influence FC. Our aims were to establish the normal levels of FC in healthy children grouped by age and analyze whether sex, gestational age, birth weight, type of delivery, type of feeding, or anthropometric data influence FC values. METHODS: This multicentre, cross-sectional, and observational study enrolled healthy donors under 18 years of age who attended their Primary Health Care Centre for their routine Healthy Child Program visits. The exclusion criteria were: (i) immunodeficiency, (ii) autoimmune or (iii) gastrointestinal disease; (iv) medication usage; (v) gastrointestinal symptoms; or (vi) positive finding in the microbiological study. RESULTS: We enrolled 395 subjects, mean age was 4.2 years (range 3 days to 16.9 years), and 204 were male. The median FC was 77.0 mcg/g (interquartile range 246). A negative correlation between age and FC was observed (Spearman's rho = -0.603, P<0.01), and none of the other factors analyzed were found to influence FC levels. CONCLUSIONS: Normal FC values in healthy children (particularly in infants) are higher than those considered to be altered in adults and show a negative correlation with age. It is necessary to reconsider the upper limits of FC levels for paediatric patients according to age, with further studies required to determine other factors that influence FC during infancy.

Recomendaciones para el diagnóstico y manejo práctico de la esofagitis eosinofílica pediátrica / Recommendations for the diagnosis and practical management of paediatric eosinophilic oesophagitis

La esofagitis eosinofílica es una enfermedad emergente, crónica, mediada por el sistema inmune y caracterizada por síntomas de disfunción esofágica e inflamación con infiltración eosinofílica aislada en el esófago. Es más frecuente en varones y en sujetos atópicos y los síntomas varían con la edad: en niños pequeños se manifiesta con vómitos, dolor abdominal y problemas con la alimentación y en niños mayores y adolescentes con disfagia e impactación alimentaria. El diagnóstico se basa en la presencia de síntomas e inflamación esofágica con ≥ 15 eosinófilos/campo de gran aumento, tras descartar otras causas de eosinofilia esofágica. Sin tratamiento, la enfermedad suele persistir y puede evolucionar a formas fibroestenóticas más frecuentes en el adulto. Las opciones terapéuticas incluyen inhibidores de la bomba de protones, dieta de eliminación empírica y corticoides deglutidos. Tras el tratamiento de inducción es aconsejable la terapia de mantenimiento. La dieta es el único tratamiento que se dirige a la causa de la enfermedad, al identificar los alimentos desencadenantes. La respuesta a los tratamientos requiere la evaluación histológica, por la escasa concordancia entre los síntomas y la inflamación esofágica. El manejo práctico de la esofagitis eosinofílica presenta desafíos debido, entre otras causas, a la falta de disponibilidad actual de fármacos específicos y a su abordaje con tratamientos dietéticos, en ocasiones, complejos. El presente documento, elaborado por el Grupo de Trabajo de Trastornos Gastrointestinales Eosinofílicos de la Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátricas, tiene como objetivo facilitar el abordaje diagnóstico y terapéutico de la esofagitis eosinofílica pediátrica, con base en las recientes guías de consenso basadas en la evidencia

Eosinophilic oesophagitis is an emerging and chronic disorder mediated by the immune system, and is characterised by symptoms of oesophageal dysfunction and inflammation with isolated eosinophil infiltration in the oesophagus. It is more common in males and in atopic subjects, and the symptoms vary with age. In younger children, there is vomiting, abdominal pain and dietary problems, with dysphagia and food impaction in older children and adolescents. The diagnosis is based on the presence of symptoms and oesophageal inflammation with ≥ 15 eosinophils / high power field, and after ruling out other causes of oesophageal eosinophilia. Without treatment, the disease usually persists and can progress to fibrostenotic forms more common in adults. The treatment options included proton pump inhibitors, empirical elimination diets, and swallowed topical corticosteroids. Maintenance therapy is advisable after the induction treatment. Diet is the only treatment that is directed at the cause of the disease, on identifying the triggering food or foods. The response to the treatments requires a histological assessment due to the poor agreement between the symptoms and the oesophageal inflammation. The practical management of Eosinophilic oesophagitis presents with challenges, due to, among other causes, the current lack of availability of specific drugs, and to its approach with, occasionally complex, diet treatments. The present document, prepared by the Working Group on Eosinophilic Gastrointestinal Disorders of the Spanish Society of Paediatric Gastroenterology, Hepatology and Nutrition, has as its objective to help in the diagnostic and therapeutic approach to paediatric eosinophilic oesophagitis, based on the recent evidence-based consensus guidelines

Sustained Remission of Eosinophilic Esophagitis Following Discontinuation of Dietary Elimination in Children.

Eosinophilic esophagitis (EoE), when left untreated, may progress from an inflammatory to a fibrostenotic phenotype. Inflammation generally recurs after treatment withdrawal. Thus, long-term treatment has been recommended. Here, we describe a cohort of children with EoE who achieved clinical and histologic remission with elimination diets, and maintained sustained untreated remission (SUR) despite re-introduction of all eliminated food allergens.

Food Protein-induced Enterocolitis Syndrome: Data From a Multicenter Retrospective Study in Spain.

OBJECTIVE: The aim of the study was to describe clinical, epidemiological, and management characteristics of food protein-induced enterocolitis syndrome (FPIES) cases in Spain. PATIENTS AND METHODS: Multicenter observational retrospective study. FPIES cases diagnosed in specialized units in Spain over 12 months in 2017 (January-December) according to the recently published international diagnostic criteria were included. RESULTS: One hundred twenty patients (53.3% boys) were included. The majority were acute cases (111) with mild-to-moderate severity (76.7%). Triggering foods were cow's milk (48/120), fish (38), egg (13), rice (12), and soy (1). The majority (84.2%) of the patients had FPIES to 1 food only. In addition to vomiting (100%), pallor (89.2%), and altered behavior (88.3%) were most frequently observed in acute forms. On the contrary, diarrhea (70%), abdominal distension (33.3%), and blood in stools (44.4%) were more frequently observed in chronic cases. Oral challenge was performed in 18.9% of the acute forms compared to 44.4% of the chronic forms. The most common treatment was intravenous fluids followed by ondansetron. Corticosteroids were used in 6 patients (5 with acute symptoms and 1 chronic). Seven patients were treated with antibiotics for suspicion of infection. Most cases of cow's milk FPIES were treated with extensively hydrolyzed formulas (69.8%). CONCLUSIONS: FPIES is not uncommon in our units. Unlike other published series, fish and egg are important triggers in our country. A greater knowledge and diffusion of the international consensus criteria will allow a better characterization of the cases and a standardization of their management.

Pediatric Eosinophilic Esophagitis: Results of the European Retrospective Pediatric Eosinophilic Esophagitis Registry (RetroPEER).

OBJECTIVES: Recommendations for diagnosing and treating eosinophilic esophagitis (EoE) are evolving; however, information on real world clinical practice is lacking. To assess the practices of pediatric gastroenterologists diagnosing and treating EoE and to identify the triggering allergens in European children. METHODS: Retrospective anonymized data were collected from 26 European pediatric gastroenterology centers in 13 countries. Inclusion criteria were: Patients diagnosis with EoE, completed investigations prescribed by the treating physician, and were on stable medical or dietary interventions. RESULTS: In total, 410 patients diagnosed between December 1999 and June 2016 were analyzed, 76.3% boys. The time from symptoms to diagnosis was 12 ±â€Š33.5 months and age at diagnosis was 8.9 ±â€Š4.75 years. The most frequent indications for endoscopy were: dysphagia (38%), gastroesophageal reflux (31.2%), bolus impaction (24.4%), and failure to thrive (10.5%). Approximately 70.3% had failed proton pump inhibitor treatment. The foods found to be causative of EoE by elimination and rechallenge were milk (42%), egg (21.5%), wheat/gluten (10.9%), and peanut (9.9%). Elimination diets were used exclusively in 154 of 410 (37.5%), topical steroids without elimination diets in 52 of 410 (12.6%), both diet and steroids in 183 of 410 (44.6%), systemic steroids in 22 of 410 (5.3%), and esophageal dilation in 7 of 410 (1.7%). Patient refusal, shortage of endoscopy time, and reluctance to perform multiple endoscopies per patient were noted as factors justifying deviation from guidelines. CONCLUSIONS: In this "real world" pediatric European cohort, milk and egg were the most common allergens triggering EoE. Although high-dose proton pump inhibitor trials have increased, attempted PPI treatment is not universal.

Estudio de la mortalidad en trabajadores del Instituto Nacional de Gestión Sanitaria (INGESA). Período del año 2000 al 2015 / Study of the mortality in workers of the National Institute of Sanitary Management (INGESA). Period 2000 to 2015

Introducción. El trabajo cotidiano en las complejas organizaciones de salud que son los hospitales, tiene características propias que las distingue de otras organizaciones y que sustenta su singularidad y complejidad ya sea por funcionar las 24 horas de los 365 días del año o por trabajar con la salud, la enfermedad y el cuidado. Por tales motivos son expuestos a riesgos diferentes del resto de la población, lo que hace interesante el estudio de su mortalidad general. Por ello este estudio se plantea describir la mortalidad y sus características más importantes en trabajadores del Instituto Nacional de Gestión Sanitaria, en el período del año 2000 al 2015.

Introduction: The daily work in the complex organizations of health that are the hospitals, has its own characteristics that distinguishes from other organizations, since people work 24 hours of 365 days of the year and for working with the health, the disease and the care. For such motives they are exposed to risks different from the rest of the population, which makes interesting the study of their general mortality. For that reason this study considers to describe the mortality and its most important characteristics in workers of the National Institute of Sanitary Management, in the period of 2000 to 2015. Methodology: Descriptive retrospective Study of the mortality in the workers of the INGESA in the period 2000 to 2015. The population were the deceased workers of the INGESA. As a support program has been used SPSS v21. The file consists of 8 variables, such as sex, age, professional category, reason of the death, date of the decease, among others. Results: there have being notified 18 dead, the average of age 51,67 years with standard deviation +/-10,91 years. 72,2 % were men. The professional category with major incident of mortality were doctors with 44,4 %, hospital porter and administrative staff 16,75 % respectively. The most frequent reason of death were neoplasias (44,4 %) followed by the ictus 22,2 % and suicides 11,1 %. The year with more deceases was 2014. Conclusions: The suitable record of the mortality in the services of prevention of labor risks, allows to observe the predominant diseases and on the basis of this information to establish preventive measures adapted to control efficiently the public health of our workers (AU)

Analysis of the Relationship between the Month of Birth and Risk of Multiple Sclerosis in a Spanish Population.

BACKGROUND: Some studies have suggested an association between the month of birth and risk of multiple sclerosis (MS), related to environmental factors, mainly sun exposure and maternal vitamin D levels. Few studies have been conducted in Southern Europe countries. Madrid has a continental climate with considerable variation of sun hours between winter and summer, so it may be relevant to study this relationship. METHODS: MS patients, born between 1932 and 2003, 1,335 of them from our database between 2004 and 2015, were analysed. The weighted average number of births per month in Madrid from 1996 and 2012 (n = 1,098,774) was considered the control population. The month and season of birth were analysed using chi-square, Hewitt's and Roberson's seasonality tests. RESULTS: Birth rate increased in June, July, and September, and decreased in November, January, and February. Births were 29% more frequent in summer (July-September) than in winter (January-March), with a ratio of 0.79. Hewitt's test for seasonality gave a rank sum of 53 between May and October (p = 0.12). Rogerson's variation was applied to 3-, 4-, and 5-month periods. Substantial differences were noted in the 5-month periods (k = 5), although the largest rank sum (June-October) was not significant (p = 0.09). CONCLUSION: Our analysis seemed to suggest that pre-natal sun exposure may have an influence on the incidence of MS, most likely in combination with other environmental or genetic factors.

The impact of the elimination diet on growth and nutrient intake in children with food protein induced gastrointestinal allergies.

BACKGROUND: Non immunoglobulin E (IgE) mediated allergies affecting the gastrointestinal tract require an elimination diet to aid diagnosis. The elimination diet may entail multiple food eliminations that contribute significantly to macro- and micro-nutrient intake which are essential for normal growth and development. Previous studies have indicated growth faltering in children with IgE-mediated allergy, but limited data is available on those with delayed type allergies. We therefore performed a study to establish the impact on growth before and after commencing an elimination diets in children with food protein induced non-IgE mediated gastrointestinal allergies. METHODS: A prospective, observational study was performed at the tertiary gastroenterology department. Children aged 4 weeks-16 years without non-allergic co-morbidities who were required to follow an elimination diet for suspected food protein induced gastrointestinal allergies were included. Growth parameters pre-elimination were taken from clinical notes and post-elimination measurements (weight and height) were taken a minimum of 4 weeks after the elimination diet. A 3-day estimated food diary was recorded a minimum of 4 weeks after initiating the elimination diet, including also any hypoallergenic formulas or over the counter milk alternatives that were consumed. RESULTS: We recruited 130 children: 89 (68.5 %) boys and a median age of 23.3 months [IQR 9.4-69.2]. Almost all children (94.8 %) in this study eliminated CM from their diet and average contribution of energy in the form of protein was 13.8 % (SD 3.9), 51.2 % (SD 7.5) from carbohydrates and 35 % (SD 7.5) from fat. In our cohort 9 and 2.8 % were stunted and wasted respectively. There was a statistically significant improvement in weight-for-age (Wtage) after the 4 week elimination diet. The elimination diet itself did not improve any of the growth parameters, but achieving energy and protein intake improved Wtage and WtHt respectively, vitamin and/or mineral supplements and hypoallergenic formulas were positively associated with WtHt and Wtage. CONCLUSION: With appropriate dietary advice, including optimal energy and protein intake, hypoallergenic formulas and vitamins and mineral supplementation, growth parameters increased from before to after dietary elimination. These factors were positively associated with growth, irrespective of the type of elimination diet and the numbers of foods eliminated.

Hipofisitis linfocitaria y paquimeningitis hipertrófica: descripción de un posible caso asociado a las patologías IgG4 / Lymphocytic hypophysitis and hypertrophic pachymeningitis: description of a possible case associated to IgG4 pathologies

Introducción. Las patologías relacionadas con la infiltración de linfocitos y células inflamatorias se clasifican, según su topografía, en patología orbitaria idiopática, paquimeningitis hipertrófica idiopática, síndrome de Tolosa-Hunt e hipofisitis linfocitaria. Presentamos a una paciente que comenzó con una hipofisitis linfocitaria hace ocho años y ha presentado varios episodios de paquimeningitis hipertrófica variables en su localización. Caso clínico. Mujer de 55 años, en seguimiento por cefalea de dos meses de evolución, que ingresó por empeoramiento clínico con parálisis del III par derecho completo, lagrimeo y rinorrea. Se realizó una resonancia magnética cerebral que demostró la presencia de una lesión sellar compatible con hipofisitis linfocitaria. Se inició tratamiento con corticoides con mejoría inicial, pero, tras dos años, la paciente presentó empeoramiento clínico con cefalea y parestesias perioculares derechas. Se repitió la resonancia, donde se observaron varias lesiones extraaxiales, siendo el resto de estudios normales, por lo que se diagnosticó paquimeningitis hipertrófica idiopática y se inició tratamiento de nuevo con corticoides. En el seguimiento posterior, la paciente presentó nuevas lesiones en diferentes localizaciones y mal control álgico, por lo que se añadió tratamiento inmunomodulador. Ante la asociación de hipofisitis linfocitaria y paquimeningitis hipertrófica, se completó el estudio con determinación de la IgG4 en el suero, que resultó negativa. Conclusiones. La asociación de hipofisitis linfocitaria y paquimeningitis hipertrófica con las patologías relacionadas con la IgG4 se ha descrito recientemente. A pesar de que en nuestra paciente no se ha confirmado el diagnóstico, se debe considerar esta relación en aquellos casos idiopáticos y, sobre todo, si se asocian otras manifestaciones sistémicas

Introduction. Pathologies related to lymphocyte infiltration and inflammatory cells are classified, according to their topography, into idiopathic orbital pathology, idiopathic hypertrophic pachymeningitis, Tolosa-Hunt syndrome and lymphocytic hypophysitis. Here we review the case of a female patient who began with lymphocytic hypophysitis eight years ago and has since presented several episodes of hypertrophic pachymeningitis in a variety of locations. Case report. Our study involves a 55-year-old female, being monitored owing to a two-month history of headaches, who was admitted to hospital as the result of a deterioration of her clinical signs and symptoms with paralysis of the whole right-side third cranial nerve, watery eyes and rhinorrhea. A magnetic resonance brain scan revealed the presence of a sellar lesion consistent with lymphocytic hypophysitis. Treatment was established with corticoids with an improvement at first, but two years later the patient’s clinical features worsened, with headaches and periocular paraesthesias on the right-hand side. Another MRI scan was performed and several extra-axial lesions were observed, the results of the other studies being normal. Idiopathic hypertrophic pachymeningitis was therefore diagnosed and treatment with corticoids was started again. In the ensuing follow-up the patient presented new lesions in different locations and poor pain control, and so immunomodulator treatment was thus added. Given the association between lymphocytic hypophysitis and hypertrophic pachymeningitis, the study was completed with determination of the IgG4 in serum, which was negative. Conclusions. The association of lymphocytic hypophysitis and hypertrophic pachymeningitis with IgG4-related pathologies have recently been reported. Although the diagnosis has not been confirmed in our patient, this relationship must be taken into account in these idiopathic cases and, above all, if they are associated with other systemic manifestations

Ante la asociacion de hipofisitis linfocitaria y paquimeningitis hipertrofica, se completo el estudio con determinacion de la IgG4 en el suero, que resulto negativa. Conclusiones. La asociacion de hipofisitis linfocitaria y paquimeningitis hipertrofica con las patologias relacionadas con la IgG4 se ha descrito recientemente. A pesar de que en nuestra paciente no se ha confirmado el diagnostico, se debe considerar esta relacion en aquellos casos idiopaticos y, sobre todo, si se asocian otras manifestaciones sistemicas.

Time to symptom improvement using elimination diets in non-IgE-mediated gastrointestinal food allergies.

BACKGROUND: The prevalence of food allergy has increased in recent decades, and there is paucity of data on time to symptom improvement using elimination diets in non-Immunoglobulin E (IgE)-mediated food allergies. We therefore aimed to assess the time required to improvement of symptoms using a symptom questionnaire for children with non-IgE-mediated food allergies on an elimination diet. METHODS: A prospective observational study was performed on patients with non-IgE-mediated gastrointestinal food allergies on an elimination diet, who completed a questionnaire that includes nine evidence-based food allergic symptoms before and after the exclusion diet. The questionnaire measured symptoms individually from 0 (no symptom) to 5 (most severe) and collectively from 0 to 45. Children were only enrolled in the study if collectively symptoms improved with the dietary elimination within 4 or 8 weeks. RESULTS: Data from 131 patients were analysed including 90 boys with a median age of 21 months [IQR: 7 to 66]. Based on the symptom questionnaire, 129 patients (98.4%) improved after 4-week elimination diet and only two patients improved after 8 weeks. A statistically significant difference before and after commencing the elimination diet was seen in all nine recorded symptoms (all p < 0.001), and in the median of overall score (p < 0.001). CONCLUSION: This is the first study attempting to establish time to improve after commencing the diet elimination. Almost all children in this study improved within 4 weeks of following the elimination diet, under dietary supervision.

High performance computing for a 3-D optical diffraction tomographic application in fluid velocimetry.

Optical Diffraction Tomography has been recently introduced in fluid velocimetry to provide three dimensional information of seeding particle locations. In general, image reconstruction methods at visible wavelengths have to account for diffraction. Linear approximation has been used for three-dimensional image reconstruction, but a non-linear and iterative reconstruction method is required when multiple scattering is not negligible. Non-linear methods require the solution of the Helmholtz equation, computationally highly demanding due to the size of the problem. The present work shows the results of a non-linear method customized for spherical particle location using GPU computing and a made-to-measure storing format.
