Increased awareness of the importance of nutrition among hospitalized children has increased the use of nutrition screening tool (NST). However, it is not well known the NST for hospitalized children. Therefore, the purpose of this study is to understand the past and present state of adult and child NST and discuss the pros and cons of each NST.

Purpose: This study evaluated the predictive role of fecal calprotectin (FC) measured at an early stage of treatment for monitoring clinical remission (CR) after six months and endoscopic remission (ER) after one year of treatment in pediatric Crohn’s disease (CD). Methods: This retrospective study included 45 patients who simultaneously underwent ileocolonoscopy and FC testing during follow-up. FC levels were measured before and after six weeks of treatment. CR was assessed after six months of treatment using Pediatric Crohn’ s Disease Activity Index and acute-phase reactants. ER was assessed after one year using the Simple Endoscopic Score for Crohn’s Disease. Results: Twenty-nine (64.4%) patients used oral prednisolone for remission induction and 16 (35.6%) patients used anti-tumor necrosis factor-alpha. Thirty (66.7%) patients achieved CR, while 24 (53.3%) achieved ER. The FC level measured after six weeks of treatment could predict CR (χ2 =9.15, p=0.0025) and ER (χ2 =12.31, p=0.0004). The δFC could predict CR (χ2 =7.91, p=0.0049), but not ER (χ2 =1.85, p=0.1738). With a threshold of ≤950.4 µg/g, FC at week six could predict CR with 76.7% sensitivity and 73.3% specificity. The area under the curve (AUC) was 0.769 (standard error 0.0773, p=0.0005). The same threshold predicted ER with 87.5% sensitivity and 71.4% specificity. The AUC was 0.774 (standard error 0.074, p=0.0002). Conclusion FC assay at an early stage of treatment can be used as a surrogate marker to predict CR and mucosal healing in pediatric CD.

PURPOSE: This study was performed to assess the clinical usefulness of transabdominal ultrasonography (TUS) in detecting peptic ulcer disease (PUD) in children. METHODS: Twenty-four patients (19 boys, 5 girls; mean age, 10.6±4.5 years [range, 3.0–17.9 years]) who were admitted to the hospital for acute abdomen or gastrointestinal bleeding and diagnosed with PUD by endoscopy and who underwent TUS were included. Clinical data were retrospectively collected by reviewing patient medical records. Gastric ulcer (GU) was suspected when the gastric wall exceeded 8 mm in thickness and had lost its five-layer structure on TUS. Duodenal ulcer (DU) was suspected if the duodenal wall thickness exceeded 5 mm. RESULTS: Sensitivity of TUS in diagnosing PUD was 66.7% for GU and 38.9% for DU. Mean age and body weight of the 11 patients suspected with PUD on TUS were 10.9±4.4 years and 38.1±17.2 kg, respectively. For 13 patients without suspected PUD, they were 12.1±4.1 years and 39.6±17.0 kg, respectively. There was a significant difference in height, weight, and body mass index between patients who were suspected to have PUD and those who were not suspected on TUS (p=0.014, 0.008, and 0.005, respectively). A significant difference in the sensitivity of TUS in diagnosing PUD was found between patients under 30 kg and those over 30 kg (88.9% and 20.0%, respectively; p=0.003). CONCLUSION: TUS investigation of the stomach and duodenum is an efficient method for PUD detection in children with low body weight. TUS can be used in preliminary diagnostic work-up before further invasive tests.

Purpose: We investigated the clinical features and factors affecting the choice of treatment modality and the course of pediatric gallstone (GS) disease. Methods: We retrospectively analyzed the medical records of 65 patients diagnosed with GS using imaging studies between January 2009 and December 2017 were included. Results: This study included 65 patients (33 boys and 32 girls; mean age, 8.5±5.3 years;range, 0.2–18 years) who primarily presented with abdominal pain (34%), jaundice (18%), and vomiting (8%). Idiopathic GS occurred in 36 patients (55.4%). The risk factors for GS included antibiotic use, obesity, hemolytic disease, and chemotherapy in 8 (12.3%), 7 (10.8%), 6 (9.2%), and 4 patients (6.2%), respectively. We observed multiple stones (including sandy stones) in 31 patients (47.7%), a single stone in 17 (26.2%), and several stones in 17 (26.2%). GS with a diameter of <5 mm occurred in 45 patients (69.2%).Comorbidities included hepatitis, choledocholithiasis, cholecystitis, and acute pancreatitis in 20 (30.8%), 11 (16.9%), 11 (16.9%), and 4 patients (6.2%), respectively. Ursodeoxycholic acid (UDCA) was administered to 54 patients (83.1%), leading to stone dissolution in 22 patients (33.8%) within 6 months. Cholecystectomy was performed in 18 patients (27.7%) (mean age, 11.9±5.1 years). Most patients treated surgically had multiple stones (83%) and stones measuring <5 mm in size (89%), and 66.7% of patients had cholesterol stones. Conclusion Cholecystectomy is feasible in patients with small-sized or large numbers of GS and those with persistent abdominal pain and/or jaundice. UDCA administration with close follow-up is recommended in patients with uncomplicated GS.

Purpose: Acetaminophen overdose accounts for the largest proportion of pediatric poisoning reported in South Korea. We investigated the characteristics and prognosis of pediatric acetaminophen overdose. Methods: We retrospectively reviewed medical records of patients younger than 19 years with acetaminophen overdose who visited the emergency department (ED) of Pusan National University Children’s Hospital from January 2009 through December 2022. We investigated age, sex, dose, clinical findings, and treatment, and compared the differences in the variables according to the intentionality of ingestion and the presence of hepatotoxicity. Results: Among the 132,691 pediatric patients who visited the ED during the period, 555 did for drug intoxication, of whom 51 with acetaminophen overdose were included in this study. The overdose was intentional in 43 patients (the intentional group; median age, 15.4 years [interquartile range, 13.9-16.8]) and accidental in 8 patients (the accidental group; 7.7 years [2.3-15.4]). The mean ingested dose was higher in the intentional group than in the accidental group (170.3 ± 129.0 vs. 105.3 ± 37.5 mg/kg; P = 0.016). Hospitalization tended to be implemented more frequently in the intentional group (53.5% vs. 12.5%; P = 0.081). All patients with hepatotoxicity (n = 10) belonged to the same group, and showed a higher or longer median age (15.9 [14.6-17.1] vs. 13.8 years [13.7-16.4]; P = 0.030), mean ingested dose (13,230.0 ± 10,544.8 vs. 7,654.0 ± 6,752.3 mg; P = 0.043), mean time from ingestion to arrival at the ED (22.6 ± 23.4 vs. 5.5 ± 6.4 hours; P = 0.048), and frequency of hospitalization (80.0% vs. 39.0%; P = 0.048). Conclusion It is necessary to track the occurrence of hepatotoxicity in patients who intentionally ingest acetaminophen.

Calcification in patients with endstage renal disease on renal replacement therapy can occur in extraskeletal area such as conjunctiva and cornea. Conjunctival and corneal calcification (CCC) has mostly has been reported in adults with endstage renal disease on hemodialysis. CCC seems to be associated with the duration of renal replacement therapy, and high CaxP value. We report a 10-year-old girl who was on peritoneal dialysis for 31 months and presented with CCC on both eyes. Her corneal calcification was resolved after the epithelial debridement and ethylenediaminetetraacetic acid(EDTA) soaking therapy.
