Pediatric endoscopy in times of pandemic: A nationwide retrospective analysis.

BACKGROUND: Gastrointestinal endoscopy is a procedure that carries an increased risk of transmission of SARS-CoV-2 infection to medical staff. In patients, COVID-19 is a risk factor for adverse events of medical procedures. This study analyzed the real-life risk of, and factors contributing to, infection transmission to endoscopic personnel, and possible adverse events of the endoscopy procedure and anesthesia in children with COVID-19. METHODS: Nationwide retrospective analysis of medical records of children with confirmed SARS-CoV-2 infection who underwent gastrointestinal endoscopy in Poland between February 2020 and February 2022. RESULTS: Fifty-eight patients were included in the analysis, 35% of whom had COVID-19 symptoms at the time of endoscopy. The dominant indications for endoscopy were foreign body or corrosive substance ingestion and gastrointestinal bleeding. Nine cases of virus transmission were registered among endoscopic personnel. In all of these cases, the endoscopy team was unaware of the patient's infection (p < 0.01), although symptoms were present in 78% of the children. Lack of use of personal protective equipment was the strongest predictor of SARS-CoV-2 transmission (p < 0.01). The risk of infection was not statistically significantly dependent on the method of anesthesia, intubation or the type of endoscopy. No statistically significant correlation was found between symptomatic infection and adverse events of endoscopy or anesthesia occurrence. There was one reported anesthesia-related adverse event involving extubation difficulties due to worsening respiratory infection symptoms. CONCLUSIONS: The risk of transmitting SARS-CoV-2 to endoscopic personnel during procedures in children is low and depends on compliance with infection prevention and control measures. Performing gastrointestinal endoscopy in children with COVID-19 does not appear to be associated with an increased risk of adverse events.

Old but Fancy: Curcumin in Ulcerative Colitis-Current Overview.

Ulcerative colitis (UC) is one of the inflammatory bowel diseases (IBD). It is a chronic autoimmune inflammation of unclear etiology affecting the colon and rectum, characterized by unpredictable exacerbation and remission phases. Conventional treatment options for UC include mesalamine, glucocorticoids, immunosuppressants, and biologics. The management of UC is challenging, and other therapeutic options are constantly being sought. In recent years more attention is being paid to curcumin, a main active polyphenol found in the turmeric root, which has numerous beneficial effects in the human body, including anti-inflammatory, anticarcinogenic, and antioxidative properties targeting several cellular pathways and making an impact on intestinal microbiota. This review will summarize the current knowledge on the role of curcumin in the UC therapy.

E-Cigarettes as a Growing Threat for Children and Adolescents: Position Statement From the European Academy of Paediatrics.

As the tobacco epidemic has waned, it has been followed by the advent of electronic nicotine delivery devices (ENDS) primarily manufactured by the tobacco industry to try to recruit replacements for deceased tobacco addicts. This document sets out the ten recommendations of the European Academy of Paediatrics (EAP) with regard to e-cigarettes and children and young people (CYP). The EAP notes that nicotine is itself a drug of addiction, with toxicity to the foetus, child and adult, and were ENDS only to contain nicotine, their use to create a new generation of addicts would be rigorously opposed. However, e-cigarettes include numerous unregulated chemicals, including known carcinogens, whose acute and long term toxicities are unknown. The EAP asserts that there is incontrovertible evidence that the acute toxicity of e-cigarettes is greater than that of "traditional" tobacco smoking, and a variety of acute pulmonary toxicities, including acute lung injuries, have been recorded due to e-cigarettes usage. The chronic toxicity of e-cigarettes is unknown, but given the greater acute toxicity compared to tobacco, the EAP cannot assume that e-cigarettes are safer in the long term. The high uptake of e-cigarettes by CYP, including under-age children, is partly fuelled by deceitful marketing and internet exposure, which is also unregulated. Although proposed as aids to smoking cessation, there is no evidence that e-cigarettes add anything to standard smoking cessation strategies. In summary, the EAP regards these devices and liquids as very dangerous, and ineluctably opposed to their use, and their direct or indirect marketing.

Inflammatory Bowel Disease in Patients with Congenital Chloride Diarrhoea.

BACKGROUND: Congenital chloride diarrhoea [CLD] is a rare autosomal recessive disease caused by mutations in the solute family carrier 26 member 3 [SLC26A3] gene. Patients suffer from life-long watery diarrhoea and chloride loss. Inflammatory bowel disease [IBD] has been reported in individual patients with CLD and in scl26a3-deficient mice. METHODS: We performed an international multicentre analysis to build a CLD cohort and to identify cases with IBD. We assessed clinical and genetic characteristics of subjects and studied the cumulative incidence of CLD-associated IBD. RESULTS: In a cohort of 72 patients with CLD caused by 17 different SLC26A3 mutations, we identified 12 patients [17%] diagnosed with IBD. Nine patients had Crohn's disease, two ulcerative colitis and one IBD-unclassified [IBD-U]. The prevalence of IBD in our cohort of CLD was higher than the highest prevalence of IBD in Europe [p < 0.0001]. The age of onset was variable [13.5 years, interquartile range: 8.5-23.5 years]. Patients with CLD and IBD had lower z-score for height than those without IBD. Four of 12 patients had required surgery [ileostomy formation n = 2, ileocaecal resection due to ileocaecal valve stenosis n = 1 and colectomy due to stage II transverse colon cancer n = 1]. At last follow-up, 5/12 were on biologics [adalimumab, infliximab or vedolizumab], 5/12 on immunosuppressants [azathioprine or mercaptopurine], one on 5-ASA and one off-treatment. CONCLUSIONS: A substantial proportion of patients with CLD develop IBD. This suggests the potential involvement of SL26A3-mediated anion transport in IBD pathogenesis. Patients with CLD-associated IBD may require surgery for treatment failure or colon cancer.

Subjective Psychophysical Experiences in the Course of Inflammatory Bowel Disease-A Comparative Analysis Based on the Polish Pediatric Crohn's and Colitis Cohort (POCOCO).

No gold standard is available to evaluate subjective psychophysical experiences in pediatric inflammatory bowel disease (IBD). We aimed to assess pain, anxiety, and limitations in social activities at diagnosis and the worst flare of the disease in relation to clinical expression, treatment and IBD severity. A total of 376 children completed the survey (Crohn's disease (CD) n = 196; ulcerative colitis (UC) n = 180). The questionnaire included 12 questions regarding pain, anxiety, and social activity, all assessed at recruitment and retrospectively at diagnosis and worst flare using a numeric rating scale. Patients that had ever been treated with systemic glucocorticosteroids scored higher in pain (p < 0.001), anxiety (p = 0.015), and social activity domains (p < 0.016) at worst flare, and the answers correlated with the number of steroid courses (p < 0.0392). The perception of social activity limitations also correlated independently with the number of immunosuppressants (p < 0.0433) and biological agents (p < 0.0494). There was no difference in retrospective perception of pain, anxiety and social activity limitations between CD and UC patients at diagnosis and the worst flare. The level of limitations in social activity correlated with hospitalisations due to relapse, days spent in the hospital, number of relapses, and severe relapses with the strongest association of rho = 0.39 (p = 0.0004). Subjective and retrospective perception of pain, anxiety, and limitations in social activity differs depending on therapy, correlates with treatment modalities, and severity measures such as hospitalisations.

Frequency of gastroesophageal reflux disease in children with adenoid hypertrophy.

OBJECTIVES: Recent studies have suggested that the reflux of gastric contents can cause adenoid hypertrophy (AH). The frequency of gastro-oesophageal reflux disease (GERD) in this AH population is unknown, but according to studies using pH-metry it may be as high as 65%. The aim of this study was to estimate the frequency of GERD among children with AH. METHODS: This was a cross-sectional, multicentre, prospective study of children with AH selected for adenoidectomy. The diagnosis of AH was made by a single laryngologist using a flexible fiberscope. All children had 24-hr multichannel intraluminal pH-impedance (MII/pH) assessment. A GERD diagnosis was made using BioVIEW software analysis after manual review by a single investigator. RESULTS: 38 consecutive patients (21 males, mean age 6.58 years) were enrolled in the study. GERD was diagnosed in 5 (13.2%) patients. A total of 1462 gastro-oesophageal reflux events (GERs) were detected by MII/pH and the majority (60.9%) were acidic. The only significant differences between the GERD-positive and GERD-negative groups were the total number of GERs, and the number of acid GERs. CONCLUSION: It is first study using MII/pH to assess the frequency of GERD in children with AH. The data suggest that GERD in children with AH seems to be not as common as it was previously raised. Further studies are needed to confirm these results.
