Consenso colombiano de la enfermedad inflamatoria intestinal pediátrica

está disponible en el texto completo

Introduction: Pediatric ulcerative colitis (CUP), pediatric Crohn's disease (PCD), and pediatric inflammatory bowel disease not classifiable (PIDNCID) have clinical and psychosocial particularities that differentiate them from those of adults and may condition different therapeutic approaches due to possible nutritional, growth and developmental repercussions, representing a challenge for the pediatrician and gastroenterologist. Objective: Develop expert consensus evidence-based recommendations for the timely and safe diagnosis and treatment of Pediatric Inflammatory Bowel Disease (PID) in children under 18 years of age for professionals caring for these patients and healthcare payers. Methodology: Through a panel of experts from the Colombian College of Pediatric Gastroenterology, Hepatology and Nutrition (COLGAHNP) and a multidisciplinary group, 35 questions were asked regarding the clinical picture, diagnosis, and treatment of PID. Through a critical review and analysis of the literature with particular emphasis on the main clinical practice guidelines (CPGs), randomized clinical trials (RCTs), and meta-analyses of the last ten years, from which the experts made 77 recommendations that responded to each of the research questions with their respective practical points. Subsequently, each of the statements was voted on within the developer group, including the statements that achieved > 80%. Results: All statements scored > 80%. PID has greater extension, severity, and evolution towards stenosis, perianal disease, extraintestinal manifestations, and growth retardation compared to adult patients, so its management should be performed by multidisciplinary groups led by pediatric gastroenterologists and prepare them for a transition to adulthood. Porto's criteria allow a practical classification of PID. In CPE, we should use the Paris classification and perform ileocolonoscopy and esophagogastroduodenoscopy, since 50% have upper involvement, using the SES-CD (UCEIS/Mayo in CUP) and taking multiple biopsies. Initial labs should include inflammatory markers and fecal calprotectin and rule out intestinal infections. Treatment, induction, and maintenance of PID should be individualized and decided according to risk stratification. Follow-up should use PCDAI and PUCAI for the last 48 hours. Immunologists and geneticists should evaluate patients with early and infantile PID. Conclusion: A consensus guideline is provided with evidence-based recommendations on timely and safe diagnosis and treatments in patients with ILD.

Invaginación intestinal como signo guía de enfermedad celíaca. Un caso clínico pediátrico / Intestinal intussusception as a key sign of Celiac Disease. A pediatric case report

La invaginación intestinal es la causa más frecuente de obstrucción intestinal entre los 6 y los 36 meses de edad. La mayoría son idiopáticas. Se ha descrito la asociación entre la enfermedad celíaca y la invaginación intestinal en la población pediátrica. Se presenta el caso de un varón de 23 meses ingresado por estancamiento ponderal en cuyo estudio ecográfico se observaron invaginaciones íleo-ileales asintomáticas repetidas.

Mutation of ten-eleven translocation-2 is associated with increased risk of autoimmune disease in patients with myelodysplastic syndrome

Background/Aims@#Myelodysplastic syndrome (MDS) is caused by genetic and epigenetic alteration of hematopoietic precursors and immune dysregulation. Approximately 20% of patients with MDS develop an autoimmune disease (AID). Here, we investigated whether particular genetic mutations are associated with AID in patients with MDS. @*Methods@#Eighty-eight genetic mutations associated with myeloid malignancy were sequenced in 73 MDS patients. The association between these mutations and AID was then analyzed. @*Results@#The median age of the 73 MDS patients was 70 years (interquartile range, 56 to 75), and 49 (67.1%) were male. AID was observed in 16 of 73 patients (21.9%). Mutations were detected in 57 (78.1%) patients. The percentage (68.8% vs. 80.7%, p = 0.32) and the mean number of mutations (1.8 ± 1.6 vs. 2.2 ± 1.8, p = 0.34) in MDS patients with or without AID were similar. However, the ten-eleven translocation- 2 (TET2) mutation rate was significantly higher in patients with AID than in those without (31.3% vs. 5.3%, respectively; p = 0.001). All TET2 mutations were variants of strong clinical significance. @*Conclusions@#Mutation of TET2 in patients with MDS may be associated with increased risk of developing AID.

Fibroblast Growth Factor-23 is associated with High-density lipoprotein in Systemic sclerosis Female patients

@#INTRODUCTION: Fibroblast growth factor-23 (FGF23) is a circulating regulator of phosphate and vitamin D metabolism and has been implicated as a putative pathogenic factor in cardiovascular disease. The objectives of this study were: to compare serum FGF23 levels between systemic sclerosis (SSc) patients and healthy controls and to investigate possible associations between FGF23 and serum lipid profile in SSc patients. METHODS: This cross-sectional study was performed in San Cecilio Hospital, Granada (Spain) from November 2017 to May 2019. We enrolled 62 consecutive female patients affected by SSc and 62 healthy women who served as controls. Cardiovascular risk factors and related biochemical parameters were collected. Serum FGF23 was analyzed using enzyme- linked immunosorbent assay (ELISA). Linear regression was used to examine the cross-sectional associations of serum FGF23 concentrations with high density lipoprotein-cholesterol (HDL-c). RESULTS: There was no significant differences in FGF23 levels between the patients and controls (78.2 ± 60.5 vs. 80.3 ± 56.3 pg/mL, p= 0.662), but we found a statistically significant inverse relationship between FGF23 and HDL-c measurements (r= -0.27; p= 0.03) in women with SSc. In addition, in the linear regression model, higher FGF23 concentrations were associated with lower HDL-c [β = -1.45 95% CI (-2.81, -0.08); p < 0.05]. CONCLUSIONS: We report an association between circulating FGF23 and HDL-c in SSc female patients, representing a novel pathway linking high FGF23 to an increased cardiovascular risk.

Accuracy of the 2008 Simplified Criteria for the Diagnosis of Autoimmune Hepatitis in Children / 대한소아소화기영양학회지

PURPOSE: Classical criteria for diagnosis of autoimmune hepatitis (AIH) are intended as research tool and are difficult to apply at patient's bedside. We aimed to study the accuracy of simplified criteria and the concordance with the expert diagnosis based on the original criteria. METHODS: A cohort of children under study for liver disorder was selected through consecutive sampling to obtain the prevalence of AIH within the group of differential diagnoses. AIH was defined, based on classical criteria, through committee review of medical reports. Validity indicators of the simplified criteria were obtained in an intention to diagnose approach. Optimal cut-off and the area under the receiver operating characteristic (ROC) curve were calculated. RESULTS: Out of 212 cases reviewed, 47.2% were AIH. For the optimal cut-off (6 points), the simplified criteria showed a sensitivity of 72.0% and a specificity of 96.4%, with a 94.7% positive and a 79.4% negative predictive value. The area under the ROC curve was 94.3%. There was a good agreement in the pre-treatment concordance between the classical and the simplified criteria (kappa index, 0.775). CONCLUSION: Simplified criteria provide a moderate sensitivity for the diagnosis of AIH, but may help in indicating treatment in cases under suspicion with 6 or more points.

The current state of calcium silicate cements in restorative dentistry: a review / Revisión del estado actual de cementos de silicato de calcio en odontología restauradora

ABSTRACT Calcium silicate cements have been used as dental materials for more than twenty years; however, their use in restorative dentistry is more recent. Better mechanical properties and shorter curing times make them suitable for a variety of applications in which they are used as a substitute of dentin, including direct/indirect pulp capping and as cavity base/liner. These materials may also be used to restore enamel temporarily. This article seeks to review the available scientific evidence with a focus on their applications in restorative dentistry. The information was gathered by reviewing original scientific research articles and literature reviews published in journals available in databases such as Medline/Pubmed and Scielo, along with technical information provided by the manufacturers of these cements. This article describes the composition, instructions for use, and curing reaction of calcium silicate cements, as well as the scientific evidence on their applications in restorative dentistry.

Is there difference of Streptococcus mutans count and adherence on amalgam and resin occlusal restorations? A blind clinical study

To compare the number of colony forming units CFU and agar adherence of S. mutans on amalgam AM and resin composite RC occlusal restorations. Sixty-five healthy patients older than 18 years with high caries risk who had at least one occlusal AM and RC restorations n=130 were selected. METHODS: The restorations were evaluated according to the alpha Ryge criteria Cohen-Kappa 0.8. For each patient, a biofilm sample was taken using an impression tray technique with previously loaded with solid trypticase yeast extract cysteine sucrose with bacitracin agar placed over the AM restorations and RC restorations in the same patients. The tray was placed inside an oven at 37 °C for 48 h, and the S. mutans count was then performed. Data were analyzed with the test Wilcoxon with a 95% confidence level. RESULTS: RC restorations had statistically significant higher number of CFU of S. mutans than AM restorations p<0.05. CONCLUSIONS: In adult patients with high caries risk, RC occlusal surfaces showed greater agar adherence of S. mutans count than AM restorations...

Indicators of the risk mechanics for Class-I and Class-II amalgam and composite resin restorations

AIM: To determine indicators of prognosis for mechanical risks of amalgam and composite resin restorations in permanent teeth. METHODS: Thirty-nine adult patients with direct clinical, photographic, radiographic and model examinations. A total of 256 restorations were classified as "not satisfactory," with Bravo or Charlie values according to the modified Ryge /USPHS criteria. The total "n" was divided into Bravo and Charlie groups according to the value obtained in the "marginal adaptation" parameter. Each of the groups was sub-divided by the type of material (amalgam and composite resins) and the class: occlusal (O) and proximal (MOD). RESULTS : Comparing the Bravo and Charlie groups, the statistically significant indicators were: the mesiodistal dimension (p=0.037), the distal isthmus (p<0.05), the average of the isthmuses (p<0.05), the distal (p<0.05) cavity depth, and the average depth of the MOD (p<0.05) cavities. It was concluded that the type and the class of the restoration are not indicators for sampling. CONCLUSIONS: With regard to the design of the cavity preparation, the valid mechanical risk indicators include the mesiodistal dimension, the distal isthmus, the average of the isthmuses, the depth of the distal cavity and the average depth of the MOD cavities. A simple clinical assessment does not provide sufficient information to establish the indicators for mechanical failure risk of restorations...

Actividad y efectos de ureasa y arginina deiminasa en saliva y biopelícula oral humana / Activity and effects of urease and arginine deiminase in saliva and oral human biofilm

El objetivo de esta revisión es mostrar los hallazgos emergentes de las potenciales propiedades anticariogénicas de biomoléculas del metabolismo oral relacionados con la producción de amonio. El análisis de la literatura soporta una nueva dimensiónpreventiva en el conocimiento de la enfermedad caries dental al estudiar la evidencia in vitro publicada, en la que el amonio producido desde la urea y la arginina del ambiente oral presentan importantes factores endógenos inhibitorios del desarrollo de lesiones de caries dental. Este hecho apoyaría la hipótesis que la producción de amonio por urealisis y por el sistema de arginina deiminasa, podrían inhibirpotencialmente el desarrollo de la caries dental por la neutralización de ácidos y la estabilización de la microbiota oral, favoreciendo las condiciones para el mantenimiento de la salud oral. Esta revisión presenta estudios de la actividad enzimática oral, que puedeconstituir un prometedor campo para establecer nuevas líneas de investigación en cariología, particularmente in vivo e in situ, destinados a establecer la efectividad y aplicación clínica de estos compuestos en la prevención de caries dental.

The purpose of this review is to present the emerging findings on the potential anti-cariogenic properties of the bioactive molecules of oral metabolism related with ammonia production. The literature analysis supports a new preventive dimension in the knowledge of dental caries disease by studying the published evidence provided by in vitro and clinical studies, in which the ammonia produced from urea and arginine in the oral environment represents an important endogenous inhibitory factor in the development of dental caries lesions. This fact would support the hypothesis that ammonia production by urease and the arginine deiminase system could potentially inhibit the development of dental caries by neutralizing acids and stabilizing the oral microbiota, thus enhancing the conditions for oral healthmaintenance. This review presents studies on the oral enzyme activity which may constitute a promising field in the definition of new lines of research in cariology, particularly in vivo and in situ, aimed at establishing the effectiveness and clinical application of these compounds in the prevention of dental caries.
