RESUMO

BACKGROUND: To assess the quality change of our single-center pediatric colonoscopy after applying bundle for bowel preparation and general anesthesia and centralize the procedure using terminal ileum (TI) intubation rate as the main indicator. METHODS: All elective colonoscopies performed for patients younger than 18 years old in MacKay Memorial Hospital from July 2015 through June 2020 (assigned to group 1, before bundle) and from August 2020 through July 2021 (assigned to group 2, after bundle) were retrospectively reviewed for demographic characteristics, indications, bowel preparation agent and cleansing level, diagnostic and therapeutic procedures, maximum intestinal level reached, and cecal intubation and total procedure time. Statistical analysis was done using P value < 0.05 considered to be significant. RESULTS: Analysis included 45 and 32 colonoscopies in group 1 and 2, respectively. Bloody stool was the most frequent indication in both groups. Both TI intubation rate (42.2 % vs. 75.0 %, P = 0.004) and biopsy rate (45.0 % vs. 75.9 %, P = 0.01) increased significantly from group 1 to group 2. The narrower standard deviation of bowel preparation score (1.93 vs. 1.15) and total procedure time (37.71 vs. 22.29) in group 2 indicated a more stable quality, although the mean showed no difference. There was no statistical difference in age, gender, body weight, cecal intubation rate, or cecal intubation time. CONCLUSION: A higher TI intubation rate and biopsy rate indicated an improved quality of pediatric colonoscopy after applying bundle including bowel preparation and general anesthesia, with additional centralization.

RESUMO

Rotor syndrome is a rare, benign, inherited disorder that is commonly associated with mild hyperbilirubinemia. It is caused by bi-allelic pathological variants in both SLCO1B1 and SLCO1B3 genes, causing defective OATP1B1 and OATP1B3 in the sinusoidal membrane and interrupted bilirubin uptake of the hepatocytes. We report five Taiwanese pediatric and adult patients aged 5-32 years presenting with conjugated hyperbilirubinemia, and were found to have genetic variants of SLCO1B1 and SLCO1B3. Two also had history of prolonged neonatal jaundice. Genetic analysis using panel-based next generation sequencing revealed three patients with homozygous mutations c.1738C>T (p.R580∗) in SLCO1B1 and a transposon LINE-1 insertion in SLCO1B3, one patient with homozygous mutations for another haplotype, c.757C>T (p.R253∗) in SLCO1B1 and c.1747+1G>A in SLCO1B3. Another patient had heterozygous c.1738C>T (p.R580∗) in SLCO1B1 linked with a LINE-1 insertion in SLCO1B3, and heterozygous c.757C>T (p.R253∗) in SLCO1B1 linked with c.1747+1G>A in SLCO1B3. In conclusion, we present the first time of genetic diagnosis of Rotor syndrome in Taiwan. Advanced genetic testing has enhanced the diagnosis of rare diseases with mild symptoms.

RESUMO

Heterotopic pancreas (HP) is defined as pancreatic tissue lacking vascular or anatomic connection with the normal pancreas. Surgical resection is often indicated for symptomatic gastric HP. However, intraoperative identification of gastric HP is often difficult during laparoscopic surgery. Herein, we describe a patient with gastric HP, which was marked with SPOT® dye (GI Supply, Camp Hill, PA, USA). The dye was seen clearly laparoscopically facilitating total excision of the lesion. The final pathology report confirmed the presence of heterotopic pancreatic tissue including pancreatic acini, small pancreatic ducts tissue with islets of Langerhans in the deep gastric submucosal area. There were no postoperative complications, and the patient was symptom-free. To the best of our knowledge, this was the first case report in the literature in which endoscopic tattooing of gastric HP before laparoscopic resection was performed. This method of localization was simple and reliable in children.

RESUMO

RATIONALE: Extraosseous Ewing's sarcoma is a rare tumor which is aggressive with poor prognosis; it can occur anywhere in the body, but scantily in the pancreas. Pancreatic Ewing's sarcoma is not reported commonly, with inconsistent clinical manifestations. In this regard, early recognition of this disease is very important for the patient's sake. PATIENT CONCERNS: A 16-year-old boy presented with left lower quadrant abdominal pain for 2 months, and left flank pain with dysuria for 1 month. DIAGNOSIS: Abdominal and renal ultrasonography found a mass between the spleen and left kidney as well as left renal pelvic dilatation. Abdominal computed tomography found a heterogenous mass derived from the tail of the pancreas. Serial examinations revealed that the mass was a pancreatic Ewing's sarcoma. Furthermore, no metastasis was documented. INTERVENTIONS: The tumor was totally excised after 6 months of chemotherapy, which included 10 courses of neoadjuvant chemotherapy with vincristine, epirubicin, and cyclophosphamide, alternating with ifosfamide and etoposide. The patient completed consolidation chemotherapy with vincristine, epirubicin, and cyclophosphamide, alternating with ifosfamide and etoposide for 5 courses. Radiotherapy was applied to the tumor-involved region and tumor bed. OUTCOMES: To date, the malignancy has not recurred since the treatment was completed 4 years ago. There are no complications from the treatment for the patient. LESSONS: The pancreas is a very rare extraosseous location for Ewing's sarcoma. Pancreatic extraosseous Ewing's sarcoma should be regarded as a differential diagnosis of non-urinary originated left flank pain with dysuria in adolescents.

RESUMO

While serous cystadenomas of the pancreas usually consist of small cysts, one rare variant has been reported to be composed of macrocysts. Herein, we present the case of the youngest patient with macrocystic serous cystadenoma (MSC) to be reported in the literature. The patient was a 17-year-old girl who presented with the major symptoms of a palpable abdominal mass accompanied by epigastric pain and vomiting for several months. A potential malignancy could not be excluded on the basis of imaging studies, which showed a large macrocystic pancreatic tumor that was 7 cm in diameter. Owing to the patient's symptoms, after diagnosing the mass as a pancreatic cystic tumor with potential malignancy and large tumor size, surgical intervention was arranged. Pathological analysis of the biopsy sample suggested MSC. By reviewing the literature, we found several unique characters of MSCs that cause them to be frequently misdiagnosed as potential malignancies. Additionally, the age of MSC occurrence was found to be lower than of general serous cystadenomas. The potential of MSC should be kept in mind by clinicians when diagnosing young people with pancreatic macrocystic lesions.

RESUMO

BACKGROUND: Omphalocele and gastroschisis are the two most common congenital abdominal wall defects; however, no previous study has focused on gastrointestinal and hepatobiliary tract malformations in these two conditions. This study aimed to investigate the demographic characteristics, coexisting congenital gastrointestinal and hepatobiliary tract anomalies, hospital course, and outcomes of patients with gastroschisis and omphalocele. METHODS: This is retrospective chart review of all patients admitted to one tertiary medical center in Taiwan between January 1, 2000 and June 30, 2020 with a diagnosis of gastroschisis or omphalocele. The medical records were reviewed to obtain demographic data regarding coexisting gastrointestinal and hepatobiliary tract anomalies and outcomes. RESULTS: Of the 51 patients included, 21 had gastroschisis and 30 had omphalocele. Gastroschisis was associated with a significantly younger maternal age and a higher incidence of small for gestational age. Of the 30 patients with omphalocele, twelve had associated gastrointestinal and hepatobiliary anomalies. Seven of the 21 patients with gastroschisis had gastrointestinal anomalies, and none had hepatobiliary anomalies. Among the omphalocele patients, three (10%) had documented malrotation, and one developed midgut volvulus. Among gastroschisis patients, four patients (19%) had malrotation, and two developed midgut volvulus. There were no statistically significant differences in postoperative complications or mortality rates between those with and without gastrointestinal/hepatobiliary tract anomalies. CONCLUSION: The diversity of coexisting gastrointestinal and hepatobiliary tract anomalies is higher in the omphalocele than in gastroschisis. In addition, we demonstrate that patients with gastroschisis or omphalocele have a higher rate of intestinal malrotation and midgut volvulus.

RESUMO

AIM: To gain insight into nutritional practices and expected growth outcomes of infants born between 34 and 36 gestational weeks defined as late preterm infants (LPT). METHODS: An anonymous online survey among paediatricians and neonatologists from Bangladesh, Indonesia, Mexico, Nigeria, Malaysia, Singapore and Taiwan was conducted from March until October 2020. The questionnaire consisted of 40 questions on the nutritional management and expected growth outcomes of LPT in and after-hospital care. RESULTS: Healthcare professionals from low to high Human Development (HDI) countries (n = 322) and very high HDI countries (n = 169) participated in the survey. Human milk was the preferred feeding, resulting in an adequate growth of LPT (weight, length and occipitofrontal circumference), according to a majority of respondents (low to high HDI, 179/265, 68% vs. very high HDI, 73/143, 51%; p = 0.002). The expected growth outcome was higher after-hospital discharge. Less than half of healthcare professionals started enteral feeding during the 1st hour of life. Lactation difficulties, limited access to human milk fortifiers and donor human milk, especially among low to high HDI countries, were reported as major hurdles. CONCLUSION: Human milk is the first feeding choice for LPT. The diverse opinions on nutritional practices and expected growth outcomes among healthcare professionals indicate the necessity to develop general nutritional guidelines for LPT.

RESUMO

Refractory anemia is not uncommon in pediatric patients, and anemia caused by gastrointestinal tract bleeding should always be kept in mind. Aside from infection or intestinal malrotation related bleeding, vascular malformation should also be considered. Blue rubber bleb nevus syndrome (BRBNS) is a rare vascular disorder consisting of multiple venous malformations. Lack of experience in pediatric BRBNS might lead to delayed diagnosis or misdiagnosis. Herein, we report a case of an eleven-year-old boy with recurrent pallor appearance and weakness diagnosed with BRBNS. After a thorough examination, he was treated with endoscopic polypectomy, and further iron supplements and folic acid. He is now under regular follow-up at our outpatient department. No complication is noted for six months. BRBNS is a rare venous malformation syndrome that mostly involves skin and the gastrointestinal tract. Multidisciplinary approach should be arranged for diagnosis and management. Up to date, no consensus for BRBNS treatment has been reached. Management usually depends on clinical symptoms and severity of damage of involved organs. The options of treatment include conservative, medical, endoscopic, and surgical management.

RESUMO

Background and Aims: Vitamin D (VD) plays an important role not only in mineral balance and skeletal maintenance but also in immune modulation. VD status was found correlated with the pathophysiology and severity of inflammatory bowel diseases and other autoimmune disorders. Epithelial barrier function is primarily regulated by the tight-junction (TJ) proteins. In this study, we try to establish an animal model by raising mice fed VD-deficient diet and to investigate the effects of VD-deficient diet on gut integrity and zonulin expression. Methods: Male C57BL/6 mice were administered either VD-deficient [VDD group, 25(OH)2D3 0 IU/per mouse] or VD-sufficient [VDS group, 25(OH)2D3 37.8 IU/per mouse] special diets for 7 weeks. Body weight and diet intake were recorded weekly. Serum VD levels were detected. After sacrifice, jejunum and colon specimens were collected. The villus length and crypt depth of the jejunum as well as mucosa thickness of the colon were measured. Various serum pro-inflammatory cytokines and intestinal TJ proteins were assessed. The serum level of zonulin and the mRNA expression of jejunum zonulin were also investigated. Results: We found that mice fed a VDD diet had a lower serum level of VD after 7 weeks (p < 0.001). VDD mice gained significant less weight (p = 0.022) and took a similar amount of diet (p = 0.398) when compared to mice raised on a VDS diet. Significantly decreased colon mucosa thickness was found in VDD mice compared with the VDS group (p = 0.022). A marked increase in serum pro-inflammatory cytokine levels was demonstrated in VDD mice. All relative levels of claudin (CLD)-1 (p = 0.007), CLD-3 (p < 0.001), CLD-7 (p < 0.001), and zonulin-1 (ZO-1, p = 0.038) protein expressions were significantly decreased in the VDD group when compared to the VDS group. A significant upregulation of mRNA expression of jejunum zonulin (p = 0.043) and elevated serum zonulin (p = 0.001) were found in the VDD group. Conclusions: We successfully demonstrated that VDD could lead to impaired barrier properties. We assume that sufficient VD could maintain intestinal epithelial integrity and prevent mucosal barrier dysfunction. VD supplementation may serve as part of a therapeutic strategy for human autoimmune and infectious diseases with intestinal barrier dysfunction (leaky gut) in the future. To our knowledge, this is the first study to demonstrate that VDD could lead to a significant upregulation in mRNA expression of the jejunum zonulin level and also a marked elevation of serum zonulin in a mouse model.

RESUMO

RATIONALE: Infantile inflammatory bowel disease (IBD) is an extremely rare subgroup of IBD that includes patients whose age of onset is younger than 2 years old. These patients can have more surgical interventions, and a severe and refractory disease course with higher rates of conventional treatment failure. Monogenic defects play an important role in this subgroup of IBD, and identification of the underlying defect can guide the therapeutic approach. PATIENT CONCERNS: In 2007, a 4-month-old girl from a nonconsanguineous family presenting with anal fistula, chronic diarrhea, and failure to thrive. She underwent multiple surgical repairs but continued to have persistent colitis and perianal fistulas. DIAGNOSIS: Crohn's disease was confirmed by endoscopic and histologic finding. INTERVENTION: Conventional pediatric IBD therapy including multiple surgical interventions and antitumor necrosis factor alpha agents were applied. OUTCOMES: The patient did not respond to conventional pediatric IBD therapy. Interleukin-10 (IL-10) receptor mutation was discovered by whole-exome sequencing and defective IL-10 signaling was proved by functional test of IL-10 signaling pathway by the age of 12. The patient is currently awaiting hematopoietic stem cell transplantation. LESSONS: Early detection of underlying genetic causes of patients with infantile-IBD is crucial, since it may prevent patients from undergoing unnecessary surgeries and adverse effects from ineffective medical therapies. Moreover, infantile-IBD patients with complex perianal disease, intractable early onset enterocolitis and extraintestinal manifestations including oral ulcers and skin folliculitis, should undergo genetic and functional testing for IL-10 pathway defect.

RESUMO

Breast feeding and human milk are the standards for infant feeding and nutrition. Human milk oligosaccharides (HMOs) are the third most abundant solid component in human milk. To date, more than 200 structural different HMOs have been identified and some can be synthesized by the food industry. HMOs are one of the major differences between human milk and formula milk, and current evidence demonstrates their various beneficial effects toward infants' health: acting as anti-adhesive antimicrobials, immune modulators, and intestinal cell response modulators, as well as providing prebiotics effect and neurodevelopment and cognition effects. HMOs compositions vary among mothers, influenced by the stage of lactation, duration of pregnancy and maternal genetic factors. However, there are still some unknown factors affecting the compositions of HMOs and requiring further research for clarification. A combination of preclinical and clinical cohort studies may help to identify whether an individual HMO contributes to disease protection. In recent years, 2'-fucosyllactose (2'-FL) and lacto-N-neotetraose (LNnT) have been approved as food ingredients by official authorities. Infant formulae supplemented with these HMOs are well-tolerated. However, more prospective clinical studies are warranted to elucidate HMOs' significance in infant nutrition. Breast milk feeding remains the best option for infants nutrition and development. Whenever breast milk is not adequate or unavailable, infant formula supplemented with HMOs might be considered as an alternative.

RESUMO

BACKGROUND: Intestinal mucositis remains one of the most deleterious side effects in cancer patients undergoing chemotherapy. We hypothesize that the probiotics could preserve gut ecology, ameliorate inflammation, and protect epithelia via immune modulations of enterocytes and intestinal stem cells. Our aim is to characterize these changes and the safety of probiotics via a 5-fluorouracil- (5-FU-) induced intestinal mucositis mouse model. METHODS: 5-FU-injected BALB/c mice were either orally administrated with saline or probiotic suspension of Lactobacillus casei variety rhamnosus (Lcr35). Diarrhea scores, serum proinflammatory cytokines, and T-cell subtypes were assessed. Immunostaining analyses for the proliferation of intestinal stem cells CD44 and Ki67 were processed. Samples of blood and internal organs were investigated for bacterial translocation. RESULTS: Diarrhea was attenuated after oral Lcr35 administration. Serum proinflammatory cytokines were significantly increased in the 5-FU group and were reversed by Lcr35. A tremendous rise of the CD3+/CD8+ count and a significant decrease of CD3+CD4+/CD3+CD8+ ratios were found in the 5-FU group and were both reversed by Lcr35. 5-FU significantly stimulated the expression of CD44 stem cells, and the expression was restored by Lcr35. 5-FU could increase the number of Ki67 proliferative cells. No bacterial translocation was found in this study. CONCLUSIONS: Our results showed that 5-FU caused intestinal inflammation mainly via Th1 and Th17 responses. 5-FU could stimulate stem cells and proliferation cells in a mouse model. We demonstrate chemotherapy could decrease immune competence. Probiotics were shown to modulate the immune response. This is the first study to analyze the immune modulation effects and safety of Lactobacillus strain on enterocytes and intestinal stem cells in a mouse model.

RESUMO

BACKGROUND: Gallstones are uncommon in infants and children and Asian children are thought to have very low risk. Diagnoses have increased in recent years with the widespread use of ultrasonography (USG). This study aimed to review our experience with risk factors, complications, and treatment of pediatric gallstones in low-incidence populations. METHODS: We retrospectively reviewed patients younger than 18 years old diagnosed with gallstones using USG between November 2006 and December 2012 in a tertiary referral hospital in Taiwan. Demographic information including age and sex, follow-up period, USG findings, predisposing factors, complications, treatment approaches and outcomes were recorded. RESULTS: Ninety-eight children with gallstones diagnosed with USG were enrolled and reviewed in our study. Females comprised 55% of patients, with no specific gender tendency. No risk factor could be identified in 30.8% of patients. The most common risk factors were cephalosporin (CS) use, presence of a choledochal cyst (CC), and spherocytosis. CS use was not associated with a higher dissolution rate. The presence of type IVa CC implied a high rate of gallstone recurrence after Roux-en-Y hepaticojejunostomy. Complications were seen in 22.4% of patients, but only two needed emergency stone removal. Expectant management was performed in 61% of patients and 62.5% of them achieved spontaneous resolution; the stone dissolution rate was not lower than in the group treated with ursodeoxycholic acid (UDCA). Stone size was significantly decreased after UDCA use if resolution did not occur. CONCLUSIONS: Pediatric gallstones showed high resolution rate, and the clinical course was largely benign. CS use was the most common risk factor and did not predict a higher dissolution rate. Type IVa CC was also an important risk factor associated with a high recurrence rate. Conservative treatment and oral UDCA may be reasonable strategies in most patients, unless complications are present.

RESUMO

BACKGROUND AND AIM: Intestinal mucositis remained one of the most deleterious complications in cancer patients undergoing chemotherapy. 5-FU treatment was reported to affect the abundance of gut microbiota and cause mucositis, which might be ameliorated by probiotics. We investigate the potential changes of 5-FU treatment and the modulations of probiotics on gut microbiota in a mouse model. METHODS: Male BALB/c mice received either 5-FU or saline (S). They were separated and fed saline, Lactobacillus casei variety rhamnosus (Lcr) and Lactobacillus reuteri DSM 17938 (BG). Lcr and BG were simultaneously administered with 5-FU for 5 days. Stool specimens were collected for DNA extraction and pyrosequenced for bioinformatic analysis. RESULTS: Fecal microbial communities were obviously diverse. Bacteroides and Bacteroidaceae were the most abundant microbiota in FU.BG group while S24_7 was the most in S.S group. At phylum and class levels, abundances of Betaproteobacteria, Erysipelotrichi, Gammaproteobacteria, and Verrucomicrobia were significantly increased in the FU groups. Probiotics supplementation did increase the abundances of Enterobacteriales and Turicibacterales. We demonstrated that probiotics did modulate the abundance and diversity of gut microbiota. Bacterial motility proteins were found enriched and upregulated in the S.BG group. No mortality was noted. No bacterial translocation was found in spleen and blood among the six groups. CONCLUSION: Gut microbiota of mice undergoing chemotherapy exhibited a distinct disruption in bacterial composition. Probiotic did modulate the abundance and diversity of gut microbiota. This is the first study to analyze the effects and safety of Lactobacillus strains on 5-FU-induced mucositis systematically and assess changes in the intestinal microbiota after probiotic intervention.

RESUMO

OBJECTIVE: This study aims to investigate the association of serum vitamin D (VD) levels with the severity of liver fibrosis (LF) in post Kasai's portoenterostomy biliary atresia (PKBA) patients living with their native liver. METHODS: In this cross-sectional study, carried out in a tertiary Children's Hospital in Taipei, Taiwan, PKBA patients living with their native liver were enrolled. Liver biochemistry data, serum 25-hydroxyvitamin D (25-OHVD), acoustic radiation force impulse (ARFI), and scores of Pediatric Quality of Life questionnaire (PedsQL) were collected. RESULTS: All the enrolled 33 PKBA patients (36.4% males), aged 1-23 years, possessed 25-OHVD less than 30ng/ml. An inverse correlation was detected between serum 25-OHVD and ARFI (r2 = 0.175; p = 0.024). We selected a cutoff value of 23ng/mL to divide PKBA patients into two groups, as the p-value was the most significant at this point when comparing the median ARFI of two groups (p = 0.003). Ten (30.3%) had 25-OHVD≥23ng/ml (HVD group), whereas 23(69.7%) had 25-OHVD<23ng/ml (LVD group). HVD group had lower ARFI (1.13m/s vs. 1.52m/s, p = 0.003), lower aspartate transaminase (AST) (29U/L vs. 64U/L, p = 0.033), and higher scores of self-reported health-related quality of life in psychosocial functioning (86.7 vs. 77.1, p = 0.047) than LVD group. CONCLUSION: VD levels are inversely associated with severity of LF in PKBA patients with native liver.

RESUMO

RATIONALE: Hepatic hemangioma is rarely discovered during the infantile period. Although most of the cases are asymptomatic, some of them may suffer life-threatening situations. In this regard, early detection is mandatory for preventing the ominous consequences that might be culminated from the disease. PATIENT CONCERNS: A 2-month-14-day-old female infant was found incidentally to have multiple hepatic lesions during a newborn ultrasound screen. She was born smoothly at term after a non-eventful pregnancy course. Physical examination was completely normal and postnatal vital signs were stable. DIAGNOSIS: Infantile multiple hepatic hemangiomas. INTERVENTION: High-resolution ultrasound and abdominal computer tomogram were conducted to confirm the diagnosis. Propranolol was started at the age of 3 months and 7 days old with an initial dosage of 1.5 mg/kg per day and increased gradually to 2.5 mg/kg per day. No obvious adverse effects were noted during the treatment course. Rapid clinical improvement with decreasing size was observed by ultrasound 10 days after the treatment. Eventually, hepatic lesions totally disappeared 4.5 months later. Propranolol in dosage of 2.5 mg/kg per day was continued until 6 months after the initial prescription. OUTCOMES: A period of 11-month follow-up revealed no evidence of recurrence of hemangiomas. LESSONS: Early diagnosis and intervention are mandatory for infantile hepatic hemangiomas to prevent possible ominous consequences. Though the propranolol therapy protocol for the disease is still under developing, the current report strengthens the recommendation to use propranolol as the first-line medication for treating infantile hepatic hemangiomas.

RESUMO

BACKGROUND: For chemotherapy patients, intestinal mucositis is a frequent complication. Previously, we evaluated the beneficial effect of oral probiotics in 5-Fluorouracil (5-FU) induced mucositis in BALB/c mice. Here, we used SCID/NOD mice instead to simulate the immunodeficiency of chemotherapy patients: first, to evaluate the safety of probiotic supplementation and second, to determine the probiotic effect in response to 5-FU intestinal mucositis. METHODS: Thirty-six SCID/NOD mice were injected with saline (three control groups) or 5-FU (three experimental groups) intraperitoneally daily for five days. Mice were given either oral saline daily, probiotic suspension of Lactobacillus casei variety rhamnosus (Lcr35, Antibiophilus™, France) or Lactobacillus acidophilus and Bifidobacterium bifidum (LaBi, Infloran™, Italy). Blood, liver, spleen, and lymph node tissue samples were evaluated for probiotic translocation via culture and Q-PCR. Weight change, diarrhea score, jejunal villus height (VH) and crypt depth (CD), and serum cytokine levels of TNF-α, IFNγ, IL-1ß, IL-6, IL-4, IL-10, IL-13, and IL-17 were also assessed. RESULTS: No weight loss was found in the SCID control group. Mean weight loss of 10.63 ± 0.87% was noted by day five in 5-FU group without probiotics but it was only 6.2 ± 0.43% if mice were given Lcr35 (p < 0.01) and 7.1 ± 1.80% (p < 0.01) if they were given LaBi. Diarrhea score of 5-FU group without probiotics was 2.0 ± 0.0 by day five, which dropped to 1.33 ± 0.17 (p < 0.05) and 1.42 ± 0.24 (p < 0.05) with Lcr35 and LaBi, respectively. Average VH significantly decreased and CD significantly increased in SCID mice given 5-FU. With probiotics, average CD improved (p < 0.05) while VH lengthened as well. Besides IL-13, all cytokine levels increased in 5-FU SCID mice. Both Lcr35 and LaBi significantly inhibited serum cytokines (p < 0.05). No probiotic strains were detected in blood cultures of any mice. CONCLUSION: Using SCID/NOD mice as a novel model for 5-FU induced intestinal mucositis, we find that probiotics Lcr35 and LaBi do not lead to bacteremia, can improve diarrhea and body weight, can restore jejunal crypt depth, and significantly inhibit cytokines TNF-α, IL-1ß, IFNγ, IL-6, IL-4, IL-10, and IL-17.

RESUMO

OBJECTIVE: Pediatric acute pancreatitis (AP) may be different from adult AP in various respects. This study focuses on the epidemiology and medical resource use of pediatric AP in Taiwan. METHODS: Patients aged 0 to 18 years with AP were identified from the Taiwan National Health Insurance Research Database based on the International Classification of Diseases, Ninth Revision code of AP 577.0. The medical resource use was measured by length of hospital stay and hospital charges. RESULTS: Between 2000 and 2013, a total of 2127 inpatient cases of pediatric AP were collected, which represented a hospitalization rate of 2.83 per 100,000 population. The incidence by age had 2 peaks, the first peak was at age 4 to 5 years old, and the second one started rising from 12 to 13 years old until adulthood. The incidence by year increased from 2.33 to 3.07 cases per 100,000 population during the study period. The average hospital stay is steady, but the medical cost is increasing. Girls have longer hospital stays, higher medical expenditures, more use of endoscopic retrograde cholangiopancreatography possibly due to more comorbidities with biliary tract diseases than boys (P < 0.05). The mortality in cases of AP is mostly associated with systemic diseases rather than AP itself. CONCLUSIONS: The incidence of pediatric AP in Taiwan is in a rising trend. There are gender differences in length of hospital stay, medical costs, use of endoscopic retrograde cholangiopancreatography and comorbidities.
