Efficacy of transcutaneous posterior tibial nerve stimulation in functional constipation.

Most children with functional constipation (FC) improve with conventional treatments. However, a proportion of children have poor treatment outcomes. Management of intractable FC may include botulinum toxin injections, transanal irrigation, antegrade enemas, colonic resections, and in some cases sacral nerve stimulation (SNS). SNS is surgically placed, not readily available and expensive. Posterior tibial nerve stimulation (PTNS) allows transmission of electronic impulses and retrograde stimulation to the sacral nerve plexus in a portable, simple and non-invasive fashion. To assess the efficacy and safety of transcutaneous PTNS for the treatment of FC in children. Single-center, prospective interventional study. Children 4-14 years with Rome IV diagnosis of FC received ten daily PTNS (30 min/day) sessions. Electrodes placed over skin of ankle. Strength of stimulus was below pain threshold. Outcomes were assessed during treatment and 7 days after. Twenty-three subjects enrolled. Two children excluded (acute gastroenteritis, COVID-19 contact). Twenty completed the study (4-14 years), (8.4 ± 3.2 years, 71.4% female). We found significant improvement in the consistency of bowel movements (BM) (p = 0.005), fecal incontinence (FI) (p = 0.005), abdominal pain presence (p = < 0.001) and intensity (p = 0.005), and a significant for improvement in blood in stools (p = 0.037). There was 86.3% improvement in abdominal pain. 96.7% reported treatment satisfaction. Only one child required rescue therapy. CONCLUSION: We found significant improvement in stool consistency, FI, abdominal pain, and hematochezia. This suggests that transcutaneous PTNS could be a promising noninvasive treatment for FC in children. Large studies are needed. WHAT IS KNOWN: • Functional constipation is one of the most common disorders in children. • Current management of functional constipation consists of an integrative approach that includes medications, diet and behavioral strategies. WHAT IS NEW: • Posterior tibial nerve stimulation is a novel noninvasive and easy to use therapy that can improve stool consistency, fecal incontinence and blood in stools.

The impact of incorporating toilet-training status in the pediatric Rome IV criteria for functional constipation in infant and toddlers.

BACKGROUND: The diagnosis of functional constipation (FC) is based on the Rome criteria. The last edition of the criteria (Rome IV) for infants and toddlers modified the criteria to differentiate toilet-trained (TT) and non-toilet-trained (NTT) children. These changes have not been validated. We aimed to understand the impact of adding toilet training to the diagnostic criteria and to assess the prevalence of FC. METHODS: Parents of infants and toddlers from six outpatient clinics (four public, two private) located in three geographically dispersed cities in Colombia completed validated questionnaires to diagnose functional gastrointestinal disorders according to Spanish version of Rome IV criteria (QPGS-IV). RESULTS: A total of 1334 children (24.4 months ±15.0) participated: 482 (36%) TT and 852 (64%) NTT. The prevalence of FC was 21.1%. The prevalence increased with age, 0-1 years 7.7%; 2 years 18.2%; 3 years 23.7%; and 4 years 37.2%. TT vs NTT for FC 41.9% vs 9.3%, respectively (OR 7.06, 95% CI 5.26-9.47, P < .0001). TT more likely to report ≥ 3 criteria (OR = 2.43, 95% CI 1.41-4.21, P = .0015). 18.3% of TT had episodes of fecal incontinence that met the frequency required by Rome for FC (≤1 episode/week). However, 87.1% had fecal incontinence less often. 7.4% of them characterized as large quantity. CONCLUSION: We found no changes in the prevalence of FC using the Rome IV criteria vs Rome III. TT children are more likely to have FC. Study suggests that changes in Rome IV criteria were potentially clinically relevant and to have adequate face validity. Future studies should confirm our findings.

Acute gastroenteritis in a pediatric population from Cali, Colombia in the post rotavirus vaccine era.

BACKGROUND: Epidemiological data from Latin America on acute gastroenteritis (AGE) in the post rotavirus vaccine era obtained using highly sensitive molecular techniques are scarce. METHODS: This prospective surveillance study was performed between March 15, 2015 and March 19, 2016 in two municipal health networks (MHNs) in Cali, Colombia to detect AGE in children <5 years of age. Consecutive sampling was performed simultaneously in all health facilities belonging to both MHNs until completion of the required sample size. Stool samples from AGE patients were tested with a nucleic acid assay for 16 pathogens. Detection frequency and incidence rates were obtained for specific pathogens according to age-group in children with AGE leading to hospitalization or outpatient care. RESULTS: Overall incidence rates of AGE-related hospitalization and outpatient care were 20 and 237 per 1000 children <5 years of age, respectively. Despite almost complete rotavirus vaccine uptake, rotavirus was the most common etiology overall, including hospitalization and outpatient treatment of 0-23-month-olds, with incidence rates of 12 and 108 per 1000 children, respectively. Norovirus incidence rates were similar to rotavirus rates in this age group and associated with high Vesikari scores. Shigella predominated in 24-59-month-olds. CONCLUSIONS: AGE remains an important cause of morbidity in children under 5 years of age, especially in those under 2 years. Rotavirus remains the leading AGE-associated pathogen, followed closely by norovirus in younger children. Preventive measures, including novel vaccination strategies, are necessary in this population to further reduce AGE-related morbidity.

Alergia alimentaria / Food allergies

Las reacciones alérgicas incluyen un amplio espectro de reacciones clínicas. Con una incidencia del 15–30% de las enfermedades alérgicas y afecta a un 8% de los niños y específicamente a la proteína de la leche de vaca entre un 5–15% de los niños. Pueden manifestarse como intolerancia o alergia dando manifestaciones respiratorias, cutáneas o gastrointestinales que pueden ser inducidos por cantidades minimas de la ingesta deproteína y cuyo tratamiento básico es la exclusión de la proteína de leche sobre todo en los primeros años de vida.

Allergic reactions include a wide spectrum of clinical reactions. With a 15-30% incidence of llergicdiseases, affecting 8% of children and specifically to the protein in cow's milk 5-15% of children hey can manifest as intolerance or allergy giving respiratory manifestations, gastrointestinal or skin can be induced by minimal amounts of protein intake and whose basic treatment is the exclusión of milk protein specially inthe early years of life.
