RESUMO

BACKGROUND: Duodenal ulcer (DU) causes various symptoms in children. The prevalence of Helicobacter pylori (Hp)-associated DU has been reducing in some regions, yet the updated trend in Taiwan is unknown. Risk factors of DU recurrence have not been comprehensively investigated in children. METHODS: This retrospective study included children diagnosed with DU to evaluate the demographics, symptoms, diagnostics, treatment, and outcomes. Specific populations (infant, surgery required) were sorted for subgroup analysis. Predictors of DU recurrence was analyzed in patients who received endoscopic follow-ups. RESULTS: A total of 488 children were included. Most patients were male (72.5%), school-aged (11.3 ± 4.8 years old), and with varied underlying diseases in one-fifth. The annual incidences were around 3-5%, with a declining trend of case numbers and the Hp-positive proportion. Hp infection, concurrent gastric ulcer, perforation, and mortality were noted in 32.7%, 16%, 1.6%, and 1% of patients. Patients with or without Hp infection showed different clinical features but similar outcomes. The characteristics of subpopulations were depicted respectively. Male sex, lower Hb level, and perforation were independent risk factors associated with recurrence. CONCLUSIONS: Hp-positive DU seems to wane. Patients with male sex, lower Hb level, or perforation at diagnosis carried a higher risk of recurrence, which may warrant active surveillance and endoscopic follow-up.

RESUMO

Introduction: Primary biliary cholangitis (PBC) is a rare and chronic autoimmune liver disease characterized by the progressive destruction of small intrahepatic bile ducts that may eventually lead to cirrhosis. PBC with features of autoimmune hepatitis (AIH) has rarely been reported in pediatric patients with genetic defects. We present the case of an adolescent with chromosome 14q24.1q24.2 deletion who was given the diagnosis of stage IV PBC with features of AIH. Case presentation: A 19-year-old male adolescent with multiple congenital abnormalities and an intellectual disability presented with abnormal liver enzymes levels and pruritus for more than 5 years. Laboratory examinations revealed elevated levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transpeptidase. After the exclusion of viral hepatitis, alpha-1 antitrypsin deficiency, Wilson's disease, and other genetic cholestatic liver diseases by laboratory tests and whole exome sequencing, a liver biopsy was performed and stage IV PBC was diagnosed. Notably, features of AIH were also noted in the histopathological report, indicating the presence of PBC with AIH features. The patient responded well to a combination therapy of ursodeoxycholic acid and steroids. Array comparative genomic hybridization analysis performed to study the congenital abnormalities revealed a 3.89 Mb 14q24.1q24.2 deletion. Conclusion: PBC with AIH features has rarely been reported in an adolescent with a chromosomal abnormality. The present case can increase awareness for early-onset PBC and its possible correlation with chromosomal defects.

RESUMO

BACKGROUND: Human adenoviruses are the most common pathogens to be isolated from cases of pediatric intussusception. However, the specific clinical characteristics of pediatric intussusception associated with adenovirus infection are poorly known. METHODS: We reviewed the medical records of pediatric patients (≤18 years of age) with intussusception treated between January 2014 and December 2020. We enrolled patients with febrile episodes, 27 with and 29 without adenovirus infections (the latter serving as control group). The demographic data, clinical characteristics, and the diagnoses and management strategies were evaluated. RESULTS: The adenovirus group exhibited a significantly longer febrile duration (4.3 ± 1.9 vs. 3.3 ± 1.1 days, p = 0.020) than the control group, with an odds ratio (OR) of 5.098 (95% confidence interval [CI] 1.223-21.254, p = 0.025). The recurrence rates were 48.1% and 13.8% in the two groups (OR 5.804; 95% CI: 1.585-21.245, p = 0.008). Most adenoviruses were non-enteric (85.2%). CONCLUSION: Adenovirus-related intussusception is associated with a longer febrile period and a higher rate of intussusception recurrence. It is recommended that patients suspected of adenovirus-related intussusception should be observed for longer than others prior to discharge.

RESUMO

Hydrometrocolpos (HMC) is a rare condition where fluids or secretions accumulate in the vagina (hydrocolpos) or up to the uterus (hydrometrocolpos). This case series study reports three infants with different etiologies and presentations of HMC and aims to review literature for proper workup upon initial diagnosis. The first neonate antenatally presented with a huge cystic mass. HMC secondary to imperforate hymen was proved, and hymenotomy was performed at 2 days of age. The second participant presented with persistent urogenital sinus and hematopoietic chimerism, possibly due to transfusion from her twin brother via placenta anastomoses. At 2 months of corrected age, she had difficult defecating, and sonogram revealed HMC with normal appearance of uterus and ovaries. Regular follow-ups and surgical reconstruction will be conducted before puberty. The third patient had cloacal malformation and multiple congenital anomalies at birth. Vesicovaginal fistula-related HMC was detected and managed with surgical drainage in the neonate stage. The girl began menstruation with dysmenorrhea at 12 years. The image studies demonstrated hematometrocolpos secondary to left-side hemivaginal septum, uterine didelphy, and ipsilateral renal agenesis, indicating Herlyn-Werner-Wunderlich syndrome. HMC can be diagnosed easily via sonogram. Careful external genitalia examinations help to identify persistent urogenital sinus or cloacal malformation. Occasionally, the HMC may be part of syndrome manifestations or associated with sex chromosome anomalies. Clinicians may conduct surveillance of renal, cardiac, and skeletal systems as well as chromosome study for early diagnosis and management.

RESUMO

BACKGROUND: To examine factors that affect the severity of pyloric hypertrophy, post-operative feeding and nutritional recovery in infantile hypertrophic pyloric stenosis (IHPS). METHODS: Medical records of infants diagnosed with IHPS at a single tertiary center between 2009 and 2018 were retrospectively reviewed. Clinical characteristics, biochemistry data and outcome were assessed for their association with the severity of pyloric hypertrophy and post-operative recovery. Nutritional recovery was assessed using weight-for-age status improvement after surgery. RESULTS: Eighty-five patients were recruited in this study. The mean pre-operative weight-for-age percentile was 18.2. Elevated bicarbonate was positively correlated with symptom duration (p = 0.007). Pyloric muscle thickness was significantly correlated with age, weight, and symptom duration (p = 0.004, 0.003, 0.008, respectively). The mean weight-for-age percentile increased to 41.6 by post-operative weeks 6-8. Pyloric muscle thickness was negatively correlated with nutritional recovery by post-operative weeks 6-8 (p = 0.003). In multivariable analysis, pyloric length related to nutritional recovery at week 1-2 postoperatively (OR = 1.42, p = 0.030, 95% CI = 0.03-1.94), and pyloric muscle thickness related to nutritional recovery at week 6-8 postoperatively (OR = 4.08, p = 0.032, 95% CI = 1.13-14.7). CONCLUSION: Our study indicated that favorable nutritional outcome and successful weight gain was observed 6-8 weeks after surgery in children with IHPS. Pyloric muscle thickness positively correlated with age, weight, symptom duration, and favorable nutritional recovery. Serum bicarbonate showed a positive correlation with symptom duration.

RESUMO

Background: Antral web is a rare cause of gastric outlet obstruction in children. The presentation is diverse, depending on the degree of obstruction. Unfortunately, the guidance of management is still lacking. Methods: This study retrospectively evaluated the presentations, management, and outcomes of the pediatric antral web based on a 20-year experience in a referral center. Results: A total of 23 cases were included. The median age of diagnosis was 10 months (interquartile range, IQR, 0.8-23 months). Main presentations comprised vomiting (83%) and upper gastrointestinal (UGI) bleeding (48%). Concurrent gastric ulcers were common (68%). A total of 13 cases (57%) underwent interventional treatment. The median duration from diagnosis to intervention (DtI) was 10 days, but five with longer DtI, ranged from 30 to 755 days. Among the 15 cases with concurrent gastric ulcers, 10 patients received intervention, immediately in six but delayed in four. Surgical treatments (N = 12) achieved a cure in 11, with one rescued by endoscopic treatment. Conclusions: Children who suffer from early gastric ulcers with outlet obstruction shall raise the suspicion of the antral web. Complete obstruction madates early intervention. Around half of the cases with adequate feeding and growth need no intervention. Recurrent obstructive symptoms or adjacent ulcers justify a switch from observation to intervention to avoid complications or growth faltering.

RESUMO

Trace elements are vital components for healthy growth, development, and physical activity. The aim of this study was to investigate the relationship between trace element (iron, zinc, copper) deficiencies and picky eating behavior, development level, and physical activity level. This cross-sectional study involved 203 children aged 4-7 years; picky eating behavior, development level, and physical activity level were assessed through questionnaires. Zinc deficiency has the highest prevalence (37.4%); 67.5% of the children were assessed as picky eaters. Children with picky eating behaviors, poor development level, or poor physical activity level have significantly lower zinc levels, and higher prevalence of zinc deficiency. Pearson's correlation coefficient indicated a positive correlation between serum zinc level and development scores (r = 0.221, p = 0.002) and physical activity scores (r = 0.469, p < 0.001). In multivariate analysis, zinc deficiency independently related to picky eating (OR = 2.124, p = 0.037, CI = 1.042-4.312), developmental level (OR = 0.893, p = 0.022, CI = 0.810-0.984), and physical activity level (OR = 0.785, p < 0.001, CI = 0.700-0.879). In conclusion, the prevalence of zinc deficiency in children aged 4-7 was high, especially in picky eaters. Zinc deficiency was significantly associated with low development and poor physical activity in early childhood.

RESUMO

Vasoactive intestinal peptide (VIP) secreting tumor (VIPoma) is a rare disease, presenting with profuse diarrhea, electrolyte imbalance, and possibly fatal outcome. The diagnosis and treatment are challenging, and no consensus guideline of management is available. The pediatric incidence remains unclear. This study comprises two pediatric case reports from a tertiary center and a literature-based case series investigating the characteristics among children. The two reported cases both presented with severe diarrhea and laboratory abnormalities, including electrolyte imbalance and elevated plasma VIP level. Case 1 received several imaging investigations, partial pancreatectomy, octreotide, and everolimus, reflecting her complicated and refractory course. Case 2 underwent total excision of suprarenal ganglioneuroblastoma, and the clinical response was significant. In both cases, varied degrees of symptomatic control, reduced plasma VIP level, and correction of electrolyte imbalance were achieved. A literature review-based case series analyzed 45 pediatric cases retrieved from the PubMed database until December 31, 2019. Demographics, clinical features, diagnostic modalities, treatments, and outcomes were presented.

RESUMO

Background: Liver abscess is an important but relatively rare disease in children. This study investigated the clinical characteristics of eligible patients at a referral tertiary center over the past two decades. Method: A 20-year retrospective study (January 2000-December 2019) enrolled 38 children diagnosed with liver abscess. Demographic data; clinical features; laboratory, imaging, and microbiological findings; management strategy; and outcomes were reviewed from the patients' medical records. Results: Thirty-eight cases of pyogenic liver abscess were identified without a culture-proven amebic or fungal abscess. The mean age of diagnosis was 9.6 ± 6.2 years, and the male-to-female ratio was 1.92: 1. Hemato-oncological (28.9%) and predisposing hepatobiliary diseases (23.7%) were the two most common predisposing factors. Fever (94.7%) was the most common presentation followed by right upper quadrant abdominal pain (42.1%) and pleural effusion (34.2%). Among the laboratory parameters, leukocytosis was common (70.3%), and all patients had elevated serum C-reactive protein levels. Increased serum levels of alanine aminotransferase, aspartate aminotransferase, direct bilirubin, and total bilirubin were found in 40.5, 48.6, 23.1, and 42.9% of the cases, respectively. The most common pathogen in blood and pus cultures was Klebsiella pneumoniae. The mean durations of intravenous antibiotic and total antibiotic use were 29.0 ± 15.7 and 45.1 ± 22.1 days, respectively. Twelve patients (31.6%) were treated with antibiotics alone, while percutaneous needle aspiration, percutaneous pigtail drainage, and surgical intervention were performed in 12 (31.6%), 10 (26.3%), and 5 (13.2%) patients, respectively. No mortality was documented in this series. Conclusion: The present study reflects a relatively declining incidence of liver abscess compared with prior studies in Taiwan. K. pneumoniae remains the most prevalent pathogen in both blood and abscess cultures in Taiwan. Proper antimicrobial therapy with timely drainage generally yielded an adequate treatment response without any mortality.

RESUMO

BACKGROUND: This study aimed to assess the prevalence of picky eating among preschool children and to evaluate the association between eating behavior and growth, physical activity, development, and health status. METHODS: A structured questionnaire was used to conduct a cross-sectional descriptive study of 300 primary caregivers of children aged 2-4 years in Taiwan. Data collected included: demographics, food preferences, eating behavior, body weight, and height, development, physical activity, and records of medical illness. Data from children defined as picky or non-picky eaters based on parental' questionnaire responses were analyzed and compared using standard statistical tests. RESULTS: The mean age of the children was 2.95 years; 162 (54%) were picky eaters. Compared with non-picky eaters, z-score of weight-for-age, height-for-age, and body mass index (BMI)-for-age in picky eaters was 0.91, 0.73, and 0.44 SD lower, respectively. There were significant differences of rates in the weight-for-age, height-for-age, and BMI-for-age percentiles <15, between picky and non-picky eaters (P = 0.04, 0.023, and 0.005, respectively). Fear of unfamiliar places, poor physical activity, constipation, and high frequency (>2 times in the past 3 months) of medical illness were significantly higher in picky eaters (P = 0.01, 0.001, 0.044, and <0.001, respectively). CONCLUSION: The prevalence of picky eaters in preschool children was high, resulting in significant detrimental impacts on growth, nutritional status, development, physical activity, and health status.

RESUMO

BACKGROUND: Acute acalculous cholecystitis (AAC) is generally considered to be a mild disease in children; however, if left untreated or treated without caution, AAC can lead to severe outcomes, such as death. The objectives of this study were to present the clinical features and identify the predictors of mortality in pediatric AAC. METHODS: Patients diagnosed with AAC between 2005 and 2012 were enrolled. AAC was defined by the presence of fever and an echo-proven thickened gallbladder wall exceeding 4 mm. A poor health outcome was defined as death. Further information related to the demographics, clinical manifestations, laboratory results, ultrasound findings, and pathogens present in the AAC patients was also collected. Predictors of mortality were identified by association analyses and confirmed by multivariate logistic regression. RESULTS: A total of 147 pediatric AAC patients (male/female = 1.01, mean age = 5.2 years) were included in this retrospective study. The most common clinical presentation was an elevated C-reactive protein level (84%) followed by hepatomegaly (80%) and anorexia (78%). AAC in children was associated with various diseases, including infectious diseases (70%), systemic diseases (13%), and malignancy (11%). Fourteen of the 147 (9.25%) patients died during the study period. The presences of thrombocytopenia, anemia, gallbladder sludge, hepatitis, and/or sepsis plus hepatitis were found to be the important predictors of AAC mortality. CONCLUSIONS: The factors associated with AAC mortality were anemia, thrombocytopenia, gallbladder sludge, hepatitis, and sepsis plus hepatitis. These predictors are likely to help clinicians identify patients who are at a high risk of poor prognoses and make appropriate clinical decisions.

RESUMO

BACKGROUND: Diagnosing intestinal strangulation as a complication of small bowel obstruction (SBO) remains a considerable challenge in children. We evaluated the clinicoradiological parameters for predicting the presence of a strangulated intestine. METHODS: We reviewed the medical records of 69 pediatric patients who underwent operation for acute SBO. Regression analysis was used to identify the parameters for predicting strangulated SBO. RESULTS: Of the 69 patients with SBO, 27 patients had intestinal strangulation and were awarded one point each towards the overall clinical score: intractable continuous abdominal pain, tachycardia, white blood cell count >13,600/mm3, and abdominal distention. Patients with a clinical score ≥2 combined with the presence of ascites in ultrasound (US) results or with wall thickness and reduced wall contrast enhancement in abdominal computed tomography (CT) scans showed strong evidence for intestinal strangulation. CONCLUSION: The combination of two or more clinical parameters, including intractable continuous abdominal pain, tachycardia, leukocytosis, and abdominal distention with the presence of ascites in US or wall thickness and reduced wall contrast enhancement in, is useful for the identification of strangulated SBO. THE TYPE OF STUDY AND LEVEL OF EVIDENCE: Prognosis study; Level III.

RESUMO

Endoscopic balloon dilatation (EBD) and surgical intervention are two most common and effective treatments for gastric outlet obstruction. Correction of gastric outlet obstruction without the need for surgery is an issue that has been tried to be resolved in these decades; this management has developed with EBD, advanced treatments like local steroid injection, electrocauterization, and stent have been added recently. The most common causes of pediatric gastric outlet obstruction are idiopathic hypertrophic pyloric stenosis, peptic ulcer disease followed by the ingestion of caustic substances, stenosis secondary to surgical anastomosis; antral web, duplication cyst, ectopic pancreas, and other rare conditions. A complete clinical, radiological and endoscopic evaluation of the patient is required to make the diagnosis, with complimentary histopathologic studies. EBD are used in exceptional cases, some with advantages over surgical intervention depending on each patient in particular and on the characteristics and etiology of the gastric outlet obstruction. Local steroid injection and electrocauterization can augment the effect of EBD. The future of endoscopic treatment seems to be aimed at the use of endoscopic electrocauterization and balloon dilatations.

RESUMO

BACKGROUND: The study aimed to investigate the molecular epidemiology of severe viral gastroenteritis (AGE) in children in Taiwan after the implementation of the rotavirus vaccine in the private sector. METHODS: Fecal samples from hospitalized children with severe AGE from April 2004 to March 2011 were examined by reverse transcription-polymerase chain reaction or polymerase chain reaction to identify enteric viral pathogens. The study period was divided to prevaccine (before September 2006) and postvaccine (after October 2006) periods. The prevalence of enteric viruses between the 2 periods was analyzed. The disease burdens of rotavirus- and norovirus-associated diseases were assessed according to vaccine implementation status and were adjusted for age. RESULTS: A total of 755 stool samples were collected from hospitalized patients with AGE; enteric viruses were identified in 586 patients (77.6%), including 44 with concomitant bacterial infection. Viral enteric infection by rotavirus, norovirus, astrovirus, sapovirus, enteric adenovirus, multiple viruses and bacterial coinfections were found in 216 (28.6%), 128 (17.0%), 24 (3.2%), 6 (0.8%), 69 (9.1 %), 99 (13.1%) and 44 (5.8%) patients, respectively. A significant increase of norovirus infection was found in the postvaccine period (P < 0.001); on the other hand, rotavirus infection in infants has been reduced substainally (P = 0.056) and the annual peak of rotavirus infection has gradually become less prominent, with a significant decline of coinfection of rotavirus with other pathogens. CONCLUSIONS: Suboptimal use of rotavirus vaccines in the private sector caused a slow but modest impact on severe rotavirus AGE, whereas norovirus infection became more common.

RESUMO

BACKGROUND: Antigenemia is commonly found in children with rotavirus infection, although its clinical significance is undetermined. The aim of this study was to evaluate the association of antigenemia with clinical manifestations and cytokine profiles in children infected by rotavirus. METHODS: In total, 68 children hospitalized with rotavirus gastroenteritis were enrolled. Serum samples were collected for detection of antigenemia and viremia. Clinical, laboratory and demographic data were analyzed. Proinflammatory, Th1 and Th2 cytokines were evaluated by bead-based flow cytometry. RESULTS: Antigenemia and viremia were found in 45.6% (n = 31) and 5.9% (n = 4) of the 68 rotavirus-infected children, respectively. The mean age of the antigenemia group was significantly greater than that of the non-antigenemia group (43.5 vs. 27.3 months; p = 0.034). The antigenemia group had a significantly shorter length of hospitalization (4.8 vs. 5.8 days; p = 0.0354) in comparison with the non-antigenemia group, and antigenemia was inversely associated with the length of hospitalization (ß = 0.31, p = 0.021). A significantly higher tumor necrosis factor (TNF)-ß level was found in the patients with antigenemia than those without (236.7 vs. 29.2 pg/mL, p = 0.026). The severity of disease and the rate of extra-intestinal manifestations did not differ between the groups. Viremia was associated with a higher fever (p = 0.012). CONCLUSIONS: Antigenemia was positively correlated with shorter hospital stay in children with rotavirus infection. Enhanced innate and T-cell-mediated immunity evidenced by up-regulation of TNF-ß was found in patients with antigenemia.

RESUMO

We, herein, report a male infant who presented with recurrent pyloric stricture after two surgeries (web excision and antropyloroplasty), which were done, respectively, at 5 days of age for congenital antral web and 6 months of age for the subsequent pyloric stricture. The patient suffered from anorexia, progressed vomiting, and weight loss gradually after the first and second surgeries, and then, endoscopy revealed severe pyloric deformity and stricture. Poor inflation was noted during endoscopic balloon dilatation because of tight pylorus; a subsequent electrocauterization and balloon dilatation were done, and the patient's clinical symptoms improved significantly 2 weeks later. A follow-up endoscopy was performed 1 month and 12 months after endoscopic therapy, showing steady regression of pyloric stricture. The patient had adequate diet intake and growth in the later 12 months.

RESUMO

The pathogenesis of necrotizing enterocolitis (NEC) is unknown. Ischemia and reperfusion (I/R) injury have been considered to be major contributing factors. More recent reports have noted that apoptosis is a significant and perhaps the principal contributor to cell death after I/R injury. Recent studies have revealed that activator protein 1 (AP-1) family proteins including c-Fos and c-Jun potentially induce either the proliferation or apoptosis of the cells in the brain, heart, kidney, and liver. c-Fos and c-Jun expression has also been reported to be upregulated in postischemic intestinal epithelial cells (IECs). Heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF) is a potent cytoprotective factor in various pathologic conditions and plays a pivotal role in mediating the earliest cellular responses to injury. This study aims to examine whether HB-EGF, a proven intestinal cytoprotective molecule, exerts its protective effects through modulation of AP-1 transcription factor after intestinal I/R injury. Thirty rats were randomly divided into the following 5 groups: (1) normal control group; (2) ischemia group; (3) I/R group; (4) ischemia group with HB-EGF (400 µg/kg), and (5) I/R group with HG-EGF (400 µg/kg). c-Fos and c-Jun messenger RNAs and protein levels were determined by real-time quantitative polymerase chain reaction (PCR) and Western analyses, respectively. Statistical analysis was performed using ANOVA with Dunn's test. The messenger RNA levels of the c-Fos and c-Jun increased after intestinal ischemia or the intestinal reperfusion phase. HB-EGF pretreatment significantly decreased c-Fos and c-Jun messenger RNAs. The expression of protein levels of c-Fos and c-Jun were correlation with the expression of messenger RNA level. HB-EGF intestinal cytoprotection is mediated, in part, by downregulation of the expression of AP-1 transcription factor after intestinal I/R injury.

RESUMO

Double-site intussusceptions are very rare in children, and only a few have been reported. Here, we report a 17-month-old boy with double intussusceptions, whose clinical manifestations were painless hematochezia and anemia. Ultrasonography demonstrated an edematous, dilated bowel and two target lesions, suggesting multiple sites of intussusception. At surgery, intussusceptions were found in the ileoileal and ileocolic segments of the intestine. The cecum and proximal ascending colon were resected because of a gangrenous ileocolic intussusception. The ileoileal intussusception was reduced manually. Postoperatively, the patient was stable with no subsequent intestinal obstruction or hemorrhage.
