RESUMO

Background: Recent regulatory and reimbursement changes facilitated the development of teleconsultation within primary care. French guidance advises against antibiotic prescribing in children in teleconsultation. We assessed paediatric antibiotic prescribing on a French teleconsultation platform. Methods: This cross-sectional observational study analysed paediatric (0-14 years) visits on a national direct-to-consumer teleconsultation platform between January 2018 and December 2021. Teleconsultations with complete information regarding diagnosis (ICD-10 coding) and prescriptions were included. We assessed antibiotic prescription rates per 100 visits across diagnoses and used logistic regression to identify factors associated with antibiotic prescribing. Results: In the 37 587 included paediatric teleconsultations (median age 3 years) performed by 713 general practitioners (GPs) and 89 paediatricians, antibiotics were prescribed for 12.1%. Respiratory tract infections (RTIs) accounted for 49.5% of antibiotic prescriptions. Antibiotic prescription rates per 100 visits were: sinusitis, 69.5%; urinary tract infections, 62.2%; pharyngitis, 59.0%; pneumonia, 45.5%; otitis, 46.6%; bronchitis, 19.6%; rhinitis, 11.6%; bronchiolitis 6.6%. Antibiotic prescription rates were higher in GPs than paediatricians [OR 2.21 (IC95% 2.07-2.35)], among physicians aged 45-54 and over 65 [OR 1.66 (1.48-1.85) and 1.48 (1.32-1.66), respectively], in female practitioners [OR 1.13 (1.05-1.21)], in children 3-6 years old [OR 1.41 (1.28-1.56)] and over 6 [OR 1.50 (1.35-1.66)], during winter [OR 1.28 (1.21-1.37)] and for RTIs [OR 1.99 (1.87-2.10)]. Antibiotic prescription rates were lower in doctors with extensive experience in teleconsultation [OR 0.92 (0.86-0.98)]. Conclusions: Despite current recommendations, paediatric patients were frequently prescribed antibiotics during acute care teleconsultations. Specific antibiotic stewardship campaigns should target paediatric teleconsultations.

RESUMO

Introduction: Access to care is a major public health concern particularly in medically underserved areas (MUAs) (Zones d'Interventions Prioritaires). Teleconsultations were legalized in France in 2010, however, have been reimbursed by the national health insurance since 2018. Large-scale studies assessing the impact of teleconsultations on access to care are limited. The objective of this study was to evaluate the impact of teleconsultations in MUAs at a national scale. Methods: An observational, multicenter cross-sectional study was conducted in seven teleconsultation centers. Teleconsultations were included if they were with patients living in France and received ambulatory care at primary ambulatory care settings by registered medical doctors between August 1 and November 30, 2021. Each center provided a randomized sample of 3,000 case data per month, yielding a total of 84,000 patients. Teleconsultation incidence was measured in MUAs and non-MUAs as the primary outcome. Results: In total, 25.1% of French patients lived in MUAs, with a mean age of 30.1 ± 0.08 years. Incidence of teleconsultations was 1,964 per 100,000 compared with 787 per 100,000 in non-MUAs (p < 0.0001). Teleconsultations were mostly performed during the day (88.6%), on weekdays (90.6%), were booked (88.3%), involved a general practitioner (GP) (89.0%), and were carried out as a video consultation (96.5%). The median delay to access was 60 min for GPs. Discussion: This was the largest study of teleconsultations in France and the first in the world to pool data from competing telemedicine companies. The incidence of teleconsultations was higher in MUAs, which may show that teleconsultations improve access to care. Clinical Trial Registration number: NCT05311241.

RESUMO

PURPOSE: The Kyleena® Satisfaction Study (KYSS) aimed to assess satisfaction and continuation with levonorgestrel-releasing intrauterine system (LNG-IUS) 12 (Kyleena®) in routine clinical practice and to evaluate factors that influence satisfaction. MATERIALS AND METHODS: This prospective, observational, multicentre, single-arm cohort study, with 1-year follow-up, was conducted in Belgium, Canada, Germany, Mexico, Norway, Sweden, Spain and the United States from 2017 to 2018. During routine counselling, women who independently selected to use LNG-IUS 12 were invited to participate in the study. KYSS assessed LNG-IUS 12 satisfaction, continuation and safety. RESULTS: Overall, there were 1126 successful LNG-IUS 12 placements, with insertion attempted in 1129 women. Most participants (833/968, 86.1%, 95% CI 83.7-88.2%, with satisfaction outcome data available) reported satisfaction with LNG-IUS 12 at 12 months (or at the final visit if the device was discontinued prematurely). Satisfaction was not associated with age, parity or motivation for choosing LNG-IUS 12. The majority of women (919/1129, 81.4%) chose to continue after 12 months. Discontinuation was not correlated with age or parity. Overall, 191 women (16.9%) reported a treatment-emergent adverse event. CONCLUSIONS: Results from KYSS provide the first real-world evidence assessing LNG-IUS 12, and demonstrate high satisfaction and continuation rates irrespective of age or parity. Clinical trial registration: NCT03182140.

RESUMO

BACKGROUND: Fecal incontinence (FI) secondary to chronic retentive constipation is a frequent demand in pediatric gastroenterology clinics. The management of constipation in children includes laxatives (polyethylene glycol, PEG), enhanced toilet training, and dietary advice. Biofeedback is a possible treatment for children above the age of 7 years with resistant FI. AIM: To analyze any changes in volume to trigger defecation (VTD) and envy score over the course of biofeedback sessions according to clinical response. METHODS: In this retrospective study, we reviewed the medical records of 23 children diagnosed with FI according to the Rome IV criteria and treated with biofeedback. For each biofeedback session, a mean VTD by subject was measured. At the end, therapy was considered a success if soiling disappeared and a failure if any persisted. The need to defecate expressed by the child was described as an envy score. A 0-10 visual analog scale was used to express the intensity of this sensation. Follow-up involved calling the parents 12 months after the biofeedback sessions had ended to assess symptoms remotely. RESULTS: The study included 19 boys and 4 girls with a median age of 10 years. Patients' ages ranged between 7 and 17 years. None of them had any associated neurological disorders. All children had FI for >1 year. The median number of soiling episodes per week was 7. The average number of biofeedback sessions was 3 (range 1-5). At the end of the rehabilitation sessions, 12 children (52%) were in the "success" group. In the latter, median VTD decreased from 97 ml to 70 ml between the first and last session. In the "failure" group, VTD decreased from 120 ml to 100 ml. The between-group difference in the median VTD at the first session was not statistically significant. The last observation carried forward (LOCF) VTD was significantly lower in the "success" group compared to the "failure" group (70 ml versus 100 ml, p = 0.03). Median envy scores decreased during the biofeedback sessions with no statistical difference between the groups at the last session. Follow-up of children in the "success" group one year after the last biofeedback session revealed that 10 patients had no relapse (83%) and 2 were lost to follow-up. CONCLUSIONS: Biofeedback might be an effective tool for the management of FI resistant to medical treatment in children.

RESUMO

Monolayered epithelia are composed of tight cell assemblies that ensure polarized exchanges. EpCAM, an unconventional epithelial-specific cell adhesion molecule, is assumed to modulate epithelial morphogenesis in animal models, but little is known regarding its cellular functions. Inspired by the characterization of cellular defects in a rare EpCAM-related human intestinal disease, we find that the absence of EpCAM in enterocytes results in an aberrant apical domain. In the course of this pathological state, apical translocation towards tricellular contacts (TCs) occurs with striking tight junction belt displacement. These unusual cell organization and intestinal tissue defects are driven by the loss of actomyosin network homoeostasis and contractile activity clustering at TCs, yet is reversed by myosin-II inhibitor treatment. This study reveals that adequate distribution of cortical tension is crucial for individual cell organization, but also for epithelial monolayer maintenance. Our data suggest that EpCAM modulation protects against epithelial dysplasia and stabilizes human tissue architecture.

RESUMO

The brush border on the apical surface of enterocytes is a highly specialized structure well-adapted for efficient digestion and nutrient transport, whilst at the same time providing a protective barrier for the intestinal mucosa. The brush border is constituted of a densely ordered array of microvilli, protrusions of the plasma membrane, which are supported by actin-based microfilaments and interacting proteins and anchored in an apical network of actomyosin and intermediate filaments, the so-called terminal web. The highly dynamic, specialized apical domain is both an essential partner for the gut microbiota and an efficient signalling platform that enables adaptation to physiological stimuli from the external and internal milieu. Nevertheless, genetic alterations or various pathological stresses, such as infection, inflammation, and mechanical or nutritional alterations, can jeopardize this equilibrium and compromise intestinal functions. Long-time neglected, the intestinal brush-border shall be enlightening again as the central actor of the complex but essential intestinal homeostasis. Here, we review the processes and components involved in brush border organization and discuss pathological mechanisms that can induce brush border defects and their physiological consequences.

RESUMO

OBJECTIVES: Microvillous inclusion disease (MVID) is a cause of intractable diarrhea in infancy. In its classic form, the disease is characterized by a severe persistent watery diarrhea starting within the first days of life. Parenteral nutrition and small bowel transplantation are the only known treatments for the affected children. Histologically, periodic acid-Schiff (PAS) staining shows accumulation of periodic acid-Schiff-positive staining material along the apical pole of enterocytes, whereas transmission electron microscopy exhibits microvillus inclusion bodies within the cytoplasm of enterocytes with rarefied and shortened microvilli and secretory granules. The objective of this work was to explore clinical, morphological, and genetic findings in cases of MVID with unusual presentations. METHODS: Clinical, histological, and genetic findings are reported for 8 cases of MVID with atypical presentation. RESULTS: The diarrhea started after several months in 3 cases. It was usually less abundant and 3 patients were weaned off parenteral nutrition. None required intestinal transplantation. Three patients experienced malformations, dysmorphy, sensory disabilities, and severe mental retardation. One had a hydrocephaly. Three patients had a cholestasis with low γ-glutamyl transferase levels. Light microscopy showed histological abnormalities consistent with MVID in all of the cases, but the lesions were sometimes focal or delayed. Transmission electron microscopy retrieved some criteria of MVID in 4 patients. Finally, 6 patients were homozygotes or compound heterozygotes for MYO5B mutations. CONCLUSIONS: This study extends the spectrum of MVID to less severe clinical presentations.

RESUMO

Tufting enteropathy (TE), also known as intestinal epithelial dysplasia (IED), is a rare congenital enteropathy related to an earlyonset of severe intractable diarrhea due to specific abnormalities of the intestinal epithelium and mutations of the EpCAM gene. TE is characterized by clinical and histological heterogeneity, such as with low or without mononuclear cell infiltration of the lamina propria, and abnormalities of basement membrane. TE can be associated with malformations, other epithelial diseases, or to abnormal enterocytes development and/or differentiation. The authors report a case of a Brazilian child with TE associated with c.556-14A>G mutation in the EpCAM gene (NM_002354.2)...


Enteropatia com formação de tufos epiteliais (ETE), também conhecida como displasia epitelial intestinal (DEI), é uma rara enteropatia congênita relacionada com um início precoce de diarreia intratável grave devido a anormalidades específicas do epitélio intestinal e mutações do gene EpCAM. ETE caracteriza-se por uma heterogeneidade clínica e histológica, como ausência ou leve infiltrado de células mononucleares na lâmina própria e anormalidades de membrana basal. Pode ser associada a malformações, outras doenças epiteliais ou anormalidades no desenvolvimento/na diferenciação dos enterócitos. Os autores relatam um caso de ETE, em uma criança brasileira, associada à mutação c.556-14A> g do gene EPCAM (NM_002354.2)...

RESUMO

Congenital tufting enteropathy (CTE) is a rare and severe enteropathy recently ascribed to mutations in the epcam gene. Here we establish SPINT2, previously ascribed to congenital sodium diarrhea, as a second gene associated with CTE and report molecular and immunohistochemistry data in 57 CTE patients. Inclusion criteria were early onset diarrhea and intestinal insufficiency with the typical histological CTE abnormalities. The clinical phenotype was registered, the entire coding regions of epcam and SPINT2 sequenced, and immunostaining of EpCAM and SPINT2 performed on intestinal biopsies. An epcam mutation was involved in 41 patients (73 %) who mainly displayed isolated digestive symptoms. Mutations severely affected gene expression since the EpCAM signal on intestinal tissues was either undetectable or low and irregular. Twelve other patients (21 %) carried mutations in SPINT2, and were phenotypically characterized by systematic association with keratitis (p < 10(-4)) and, for half of them, with choanal atresia (p < 10(-4)). Dependency on parenteral nutrition (PN) was comparable in patients with epcam or SPINT2 mutations, but the frequent epcam mutation c.556-14A>G (abnormal splicing) was significantly associated with a better outcome (p = 0.032) with milder PN dependency to weaning in some cases. Finally, four patients (7 %) with isolated digestive symptoms had no detectable epcam or SPINT2 mutation. Two candidate genes, Elf3 and Claudin7, were excluded from this population. Our study allows us to separate CTE patients into at least three genetic classes, each with specific phenotypes. The genetics approach raises the question of the distinction between two congenital enteropathies. Our findings should help improve the diagnosis of CTE, guide toward strategies of long-term PN management, and limit indications for intestinal transplantation to life-threatening PN complications.

RESUMO

BACKGROUND: Small bowel transplantation has now become a recognized treatment of irreversible, permanent, and subtotal intestinal failure. OBJECTIVE: The aim of this study was to assess intestinal absorption at the time of weaning from parenteral nutrition in a series of children after intestinal transplantation. DESIGN: Twenty-four children (age range: 14-115 mo) received intestinal transplantation, together with the liver in 6 children and the colon in 16 children. Parenteral nutrition was slowly tapered while increasing enteral tube feeding. The absorption rate was measured from a 3-d stool balance analysis performed a few days after the child had weaned from parenteral nutrition to exclusive enteral tube feeding. Results were analyzed according to the resting energy expenditure (REE; Schofield formula). RESULTS: All children were weaned from parenteral nutrition between 31 and 85 d posttransplantation. Median intakes were as follows: energy, 107 kcal · kg(-1) · d(-1) (range: 79-168 kcal · kg(-1) · d(-1)); lipids, 39 kcal · kg(-1) · d(-1) (range: 20-70 kcal · kg(-1) · d(-1)); and nitrogen, 17 kcal · kg(-1) · d(-1) (range: 11-27 kcal · kg(-1) · d(-1)). Median daily stool output was 998 mL/d (range: 220-2025 mL/d). Median absorption rates were 88% (range: 75-96%) for energy, 82% (range: 55-98%) for lipids, and 77% (range: 61-88%) for nitrogen. The ratios for ingested energy to REE and absorbed energy to REE were 2.2 (range: 1.6-3.6) and 1.8 (range: 1.3-3.3), respectively. CONCLUSION: These data indicate a suboptimal intestinal graft absorption capacity with fat malabsorption, which necessitates energy intakes of at least twice the REE.

RESUMO

Mutations of the EPCAM gene have been recently identified in Congenital Tufting Enteropathy (CTE), a severe autosomal recessive gastrointestinal insufficiency of childhood requiring parenteral nutrition and occasionally intestinal transplantation. Studying seven multiplex consanguineous families from the Arabic peninsula (Kuwait and Qatar) we found that most patients were homozygote for a c.498insC mutation in exon 5. The others carried a novel mutation IVS4-2A→G. Both mutations were predicted to truncate the C-terminal domain necessary to anchorage of EPCAM at the intercellular membrane. Consistently, immunohistochemistry of intestinal biopsies failed to detect the EPCAM protein at the intercellular membrane level. The c.498insC mutation was found on the background of a minimal common haplotype of 473kb suggesting a very old founder effect (5000-6000 yrs).

RESUMO

PURPOSE: To study the value of conjunctival biopsy in congenital tufting enteropathy diagnosis. DESIGN: Case-comparative study. METHODS: Between January 2000 and June 2007, all children seeking treatment with an early onset of intractable diarrhea were examined in the ophthalmology department of Necker-Enfants Malades Hospital, Assistance Publique-Hôpitaux de Paris, France. Children underwent complete ophthalmologic examination with concurrent conjunctival and intestinal biopsies. Main outcome measures were age at diagnosis, associated disorders, parenteral nutrition, and ophthalmologic symptoms. Conjunctival biopsies support diagnosis in the presence of specific alteration. RESULTS: Twenty patients were included. The mean age of the population was 30.2 months. Congenital tufting enteropathy was diagnosed in 15 cases. In the congenital tufting enteropathy group, 10 children exhibited ophthalmic functional disorders since the first months of life, with superficial punctate keratitis and conjunctivitis and in addition alacrima and cataract in 1 case, respectively, whereas 5 children had asymptomatic conjunctival hyperemia at presentation. Conjunctival biopsies showed epithelial parakeratosis, hyperplasia, basal cells hyperplasia, and tufts. In some cases, the lamina propria contained inflammatory cells or fibrosis, and the density of goblet cells then was abnormal. In the comparison group of 5 children with early-onset intractable diarrhea but without congenital tufting enteropathy diagnosis, no tuft occurrence was observed. CONCLUSIONS: In cases of intractable diarrhea in infancy, even without ocular symptoms, a systematic ophthalmologic examination should be performed. It also should be associated with the pathologic examination of both the conjunctival and the intestine mucosae, which helps to diagnose congenital tufting enteropathy (adhesion molecules disease). Specific conjunctival findings allow affirmation of congenital tufting enteropathy before the genetic confirmation of an EpCAM gene mutation.

RESUMO

Intestinal epithelial dysplasia (IED), also known as tufting enteropathy, is a congenital enteropathy presenting with early-onset severe intractable diarrhea causing sometimes irreversible intestinal failure. To date, no epidemiological data are available, however, the prevalence can be estimated at around 1/50,000-100,000 live births in Western Europe. The prevalence seems higher in areas with high degree of consanguinity and in patients of Arabic origin. Infants develop within the first days after birth a watery diarrhea persistent in spite of bowel rest and parenteral nutrition. Some infants are reported to have associated choanal rectal or esophageal atresia. IED is thought to be related to abnormal enterocytes development and/or differentiation. Nonspecific punctuated keratitis was reported in more than 60% of patients. Histology shows various degree of villous atrophy, with low or without mononuclear cell infiltration of the lamina propria but specific histological abnormalities involving the epithelium with disorganization of surface enterocytes with focal crowding, resembling tufts. Several associated specific features were reported, including abnormal deposition of laminin and heparan sulfate proteoglycan (HSPG) in the basement membrane, increased expression of desmoglein and ultrastructural changes in the desmosomes, and abnormal distribution of alpha2beta1 integrin adhesion molecules. One model of transgenic mice in which the gene encoding the transcription factor Elf3 is disrupted have morphologic features resembling IED. Parental consanguinity and/or affected siblings suggest an autosomal recessive transmission but the causative gene(s) have not been yet identified making prenatal diagnosis unavailable. Some infants have a milder phenotype than others but in most patients, the severity of the intestinal malabsorption even with enteral feeding make them totally dependent on daily long-term parenteral nutrition with a subsequent risk of complications. IED becomes an indication for intestinal transplantation, while timing of referral for it is crucial before the onset of severe complications.
