- BRAZILIAN CONSENSUS ON THE MANAGEMENT OF INFLAMMATORY BOWEL DISEASES IN PEDIATRIC PATIENTS: A CONSENSUS OF THE BRAZILIAN ORGANIZATION FOR CROHN’S DISEASE AND COLITIS (GEDIIB)(2022) LOMAZI, Elizete Aparecida; OBA, Jane; RODRIGUES, Maraci; MARMO, Michela Cynthia da Rocha; SANDY, Natascha Silva; SDEPANIAN, Vera Lucia; IMBRIZI, Marcello; BAIMA, Júlio Pinheiro; MAGRO, Daniéla Oliveira; ALBUQUERQUE, Idblan Carvalho de; ZABOT, Gilmara Pandolfo; CASSOL, Ornella Sari; SAAD-HOSSNE, RogérioABSTRACT Background: Approximately 25% of patients with inflammatory bowel disease (IBD) develop the disease during childhood or adolescence and treatment aims to control active symptoms and prevent long-term complications. The management of Crohn’s disease (CD) and ulcerative colitis (UC) can be especially challenging in children and adolescents, related to particularities that may affect growth, development, and puberty. Objective: This consensus aims to provide guidance on the most effective medical and surgical management of pediatric patients with CD or UC. Methods: Experts in Pediatric IBD representing Brazilian gastroenterologists (Brazilian Organization for Crohn’s Disease and Colitis [GEDIIB]) developed this consensus. A rapid review was performed to support the recommendations/statements. Medical and surgical recommendations were structured and mapped according to the disease type, disease activity, and indications and contraindications for medical and surgical treatment. After structuring the statements, the modified Delphi Panel methodology was used to conduct the voting. The process took place in three rounds: two using a personalized and anonymous online voting platform and one face-to-face. Whenever participants did not agree with a specific recommendation, an option to explain why was offered to enable free-text responses and provide the opportunity for the experts to elaborate or explain disagreement. The consensus of recommendations in each round was accepted when reached ≥80% agreement. Results and conclusion: The recommendations are presented according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/ patient monitoring after initial treatment, follow-up/ patient monitoring after initial treatment. Surgical recommendations were grouped according to disease type and recommended surgery. The target audience for this consensus was general practitioners, gastroenterologists, and surgeons interested in the treatment and management of pediatric CD and UC. Additionally, the consensus aimed to support the decision-making of health insurance companies, regulatory agencies, and health institutional leaders and/or administrators.
- Small and large bowel anatomy is associated with enteral autonomy in infants with short bowel syndrome: A retrospective cohort study(2024) SANDY, Natascha S.; ROBERTS, Amin J.; WALES, Paul W.; TOMA, Ricardo K.; BELZA, Christina; DOGRA, Harween; EVANS, Helen M.; GATTINI, Daniela; HIND, Jonathan; MERCER, David; POVONDRA, Jill M.; TURNER, Justine; YAP, Jason; WONG, Theodoric; AVITZUR, YaronBackground: Achievement of enteral autonomy (EA) is the ultimate treatment goal in pediatric intestinal failure (IF). We aimed to assess predictors of EA in pediatric short bowel syndrome (SBS) and explore the impact of residual small bowel (SB) and large bowel (LB) length on EA.Methods: A retrospective cohort study was performed on infants aged <12 months (n = 367, six centers) with SBS referred between 2010 and 2015. The cohort was stratified based on the achievement of EA. Statistical testing was completed using t-test, chi-square, Cox proportional hazards regression model, and Kaplan-Meier analysis.Results: EA was achieved in 229 patients. In the multivariable analysis, the percentage of residual LB (hazard ratio [HR] = 1.02; 95% CI = 1.01-1.02) and SB (HR = 1.01; 95% CI = 1.01-1.02) length, presence of the ileocecal valve (HR = 2.02; 95% CI=1.41-2.88), and not coming from a high-volume transplantation center (HR = 2.42; 95% CI = 1.68-3.49) were positively associated with EA, whereas a negative association was seen with the presence of stoma at the time when shortest remnant was documented (HR = 0.72; 95% CI = 0.52-1.00). EA achievement was significantly different between the anatomical subgroups (log-rank test P < 0.001) with an EA rate of 80.4% in infants with >= 50% SB and LB (median time 209 days); 62.5% with >= 50% SB and <50% LB (397 days); 58.3% with <50% SB and >= 50% LB (1192 days), and 25.9% with <50% SB and LB. Necrotizing enterocolitis (NEC) was not associated with a better achievement of EA (NEC vs other etiologies: log-rank test P = 0.33).Conclusions: Overall, 62% of infants with IF secondary to SBS achieved EA over a mean time of follow-up of 2.3 years. A colon length of >50% can compensate for the loss of small bowel (<50%) and account for similar EA rates as those in children with residual SB > 50%.
- Can the learning of laparoscopic skills be quantified by the measurements of skill parameters performed in a virtual reality simulator?(2013) SANDY, Natascha Silva; CRUZ, Jose Arnaldo Shiomi da; PASSEROTTI, Carlo Camargo; NGUYEN, Hiep; REIS, Sabrina Thalita dos; GOUVEIA, Eder Maxwell; DUARTE, Ricardo Jordao; BRUSCHINI, Homero; SROUGI, MiguelPurpose: To ensure patient safety and surgical efficiency, much emphasis has been placed on the training of laparoscopic skills using virtual reality simulators. The purpose of this study was to determine whether laparoscopic skills can be objectively quantified by measuring specific skill parameters during training in a virtual reality surgical simulator (VRSS). Materials and Methods: Ten medical students (with no laparoscopic experience) and ten urology residents (PGY3-5 with limited laparoscopic experience) were recruited to participate in a ten-week training course in basic laparoscopic skills (camera, cutting, peg transfer and clipping skills) on a VRSS. Data were collected from the training sessions. The time that individuals took to complete each task and the errors that they made were analyzed independently. Results: The mean time that individuals took to complete tasks was significantly different between the groups (p < 0.05), with the residents being faster than the medical students. The residents' group also completed the tasks with fewer errors. The majority of the subjects in both groups exhibited a significant improvement in their task completion time and error rate. Conclusion: The findings in this study demonstrate that laparoscopic skills can be objectively measured in a VRSS based on quantified skill parameters, including the time spent to complete skill tasks and the associated error rate. We conclude that a VRSS is a feasible tool for training and assessing basic laparoscopic skills.
- Clinical Aspects and Etiologic Investigation of Pediatric Patients With Acute Liver Failure(2023) LUGLIO, Michele; MARQUES, Tatiana de Carvalho Silva; PEREIRA, Maria Fernanda Badue; DELGADO, Artur Figueiredo; CARVALHO, Werther Brunow de; TANNURI, Ana Cristina Aoun; SANDY, Natascha Silva; LITVINOV, Nadia; PAULA, Camila Sanson Yoshino de; SANTOS, Ariane Guissi dos; LAZARI, Carolina dos Santos; GOUVEA, Michele Soares Gomes; PAULA, Anderson Vicente de; MENDOZA, Tania Regina Tozetto; TANIGAWAH, Ryan Yukimatsu; LIMAH, Fabiana Roberto; HIRAYAMAH, Andre Bubna; SANTOS, Isabela Gusson Galdino dos; PINHOG, Joao Renato Rebello; SABINOG, Ester Cerdeira; MENDES-CORREAHG, Maria Cassia; ALVESH, Venancio Avancini Ferreira; MARQUESC, Heloisa Helena de SousaA new outbreak of hepatitis of unknown origin raised awareness in the international community. A few reports have attempted to associate new cases with adenovirus infection and the immunologic effects of previous SARS-CoV-2 infections through a superantigen mechanism. Moreover, according to a case series, viral isolates were identified in 7 of 10 cases of pediatric patients with hepatitis of unknown origin and acute liver failure. Adenovirus was detected by respiratory secretion polymerase chain reaction in 2 patients, with neither presenting with SARS-CoV-2 acute infection. Clinical and laboratory descriptions and cross-referencing epidemiologic and pathophysiological data can help identify possible disease etiologies.
