RESUMEN

OBJECTIVES: To construct a nomogram that predicts the risk of surgery in patients with necrotizing enterocolitis (NEC). METHODS: This retrospective cohort study recruited patients diagnosed with NEC at the Children's Hospital of Soochow University from 2013 to 2023. The neonates were divided into conservative and surgical-treatment groups. Univariate and multivariate logistic regressions were performed to identify factors influencing surgical risk, and a predictive model was constructed. RESULTS: This study comprised 154 cases of NEC, 103 cases (66.9%) in the conservative group and 51 cases (33.1%) in the surgical group. Multivariate logistic regression analysis revealed that increased bloody stools [odds ratio (OR) 5.066; 95% confidence interval (CI) 1.7396-14.7532; p = 0.0029), oxygen inhalation (OR 1.8278; 95% CI 1.2113-2.7581; p = 0.0041), use of vasoconstrictors (OR 4.4446; 95% CI 1.7157-11.5137; p = 0.0021), portal venous gas (OR 4.5569; 95% CI 1.6324-12.7209; p = 0.0038), and blood sodium (OR 0.8339; 95% CI 0.7477-0.9301; p = 0.0011) were independent factors of surgical risk. The area under the nomogram's receiver operating characteristic (ROC) curve was 0.886. Decision curve analysis (DCA) and calibration curves demonstrated good predictive performance for the nomogram. CONCLUSIONS: The nomogram effectively assessed the risk of surgical intervention in NEC patients, providing new insights and references for diagnosing and treating NEC.

RESUMEN

BACKGROUND: Neuroblastoma (NB), a type of solid tumor in children, has a poor prognosis. Few blood biomarkers can accurately predict the prognosis, including recurrence and survival, in children with NB. In this study, we found that the serum total cholesterol (Tchol) level was associated with the prognosis of patients through a retrospective study. METHODS: Multivariate Cox regression model was used to identify the independent risk factors in the children with NB. Kaplan-Meier method was used to analyze the correlation between the common biomarkers, including the serum Tchol level, and the prognosis of the patients. ROC curves were used to predict the accuracy of the International Neuroblastoma Staging System (INSS) stage and Children's Oncology Group (COG) risk stratification after adding the serum Tchol level. RESULTS: Compared with the other patients, serum Tchol level was significantly increased in the relapsed and died patients (P < 0.05). Subsequently, serum Tchol level was found as an independent risk factor to affect the outcome of patients (P < 0.05). Finally, we added serum Tchol level into traditional stage and risk classification system to form the new INSS stage and COG risk classification system. It was found that the areas under the ROC curve (AUC) of recurrence-free survival in the new INSS stage and COG risk classification system were increased to 0.691 (95%CI: 0.535-0.847) and 0.748 (95%CI: 0.622-0.874), respectively. Moreover, the AUC areas of overall survival in the new INSS stage and COG risk classification system were increased to 0.722 (95%CI: 0.561-0.883) and 0.668 (95%CI: 0.496-0.819), respectively. CONCLUSION: We found that serum Tchol level, a clinical biomarker, is a risk factor for recurrence and death among the children with NB. The serum Tchol level could significantly increase the accuracy of the prediction for NB prognosis.

RESUMEN

OBJECTIVE: To investigate the potential association between preterm birth and infantile appendicitis. METHODS: We conducted a retrospective, multicenter, matched case-control study. This study included consecutive patients <1 year of age with surgery- or autopsy-confirmed appendicitis, admitted between December 2007 and May 2023. For each case, 10 healthy infants were randomly selected and matched by age. Infants were categorized as neonates (0 to 28 days) or older infants (>28 days and <1 year). RESULTS: The study included 106 infants diagnosed with appendicitis (median age 2.4 months) and 1060 age-matched healthy controls. In the univariate analysis, preterm birth was significantly associated with the development of appendicitis within the first year of life (odds ratio [OR], 4.23; 95% confidence interval [CI], 2.67-6.70). Other factors associated with a higher risk of infantile appendicitis included being male (OR, 1.91; 95%CI, 1.25-2.94), weight-for-age z-score (OR, 0.72; 95%CI, 0.64-0.81), and exclusively fed on formula (OR, 2.95; 95%CI, 1.77-4.91). In multivariable analyses, preterm remained significantly associated with appendicitis (adjusted OR, 3.32; 95%CI, 1.76-6.24). Subgroup analysis revealed that a preterm birth history increased the risk of appendicitis in both neonates (adjusted OR, 4.56; 95%CI, 2.14-9.71) and older infants (adjusted OR, 3.63; 95%CI, 1.72-7.65). However, preterm did not significantly influence the incidence of appendiceal perforation. CONCLUSIONS: Preterm infants have an increased risk of appendicitis during the first year of life. A preterm birth history may help improve the timely diagnosis of infantile appendicitis.

RESUMEN

Introduction: Proprotein convertase subtilisin/kexin-9 (PCSK9) has been primarily studied in the cardiovascular field however, its role in cancer pathophysiology remains incompletely defined. Recently, a pivotal role for PCSK9 in cancer immunotherapy was proposed based on the finding that PCSK9 inhibition was associated with enhancing the antigen presentation efficacy of target programmed cell death-1 (PD-1). Herein, we provide results of a comprehensive pan-cancer analysis of PCSK9 that assessed its prognostic and immunological functions in cancer. Methods: Using a variety of available online cancer-related databases including TIMER, cBioPortal, and GEPIA, we identified the abnormal expression of PCSK9 and its potential clinical associations in diverse cancer types including liver, brain and lung. We also validated its role in progression-free survival (PFS) and immune infiltration in neuroblastoma. Results: Overall, the pan-cancer survival analysis revealed an association between dysregulated PCSK9 and poor clinical outcomes in various cancer types. Specifically, PCSK9 was extensively genetically altered across most cancer types and was consistently found in different tumor types and substages when compared with adjacent normal tissues. Thus, aberrant DNA methylation may be responsible for PCSK9 expression in many cancer types. Focusing on liver hepatocellular carcinoma (LIHC), we found that PCSK9 expression correlated with clinicopathological characteristics following stratified prognostic analyses. PCSK9 expression was significantly associated with immune infiltrate since specific markers of CD8+ T cells, macrophage polarization, and exhausted T cells exhibited different PCSK9-related immune infiltration patterns in LIHC and lung squamous cell carcinoma. In addition, PCSK9 was connected with resistance of drugs such as erlotinib and docetaxel. Finally, we validated PCSK9 expression in clinical neuroblastoma samples and concluded that PCSK9 appeared to correlate with a poor PFS and natural killer cell infiltration in neuroblastoma patients. Conclusion: PCSK9 could serve as a robust prognostic pan-cancer biomarker given its correlation with immune infiltrates in different cancer types, thus potentially highlighting a new direction for targeted clinical therapy of cancers.

RESUMEN

BACKGROUND: This study aimed to identify survival risk factors in Chinese children with hepatoblastoma (HB) and assess the effectiveness of the new treatment protocol proposed by the Chinese Children's Cancer Group (CCCG) in 2016. METHODS: A multicenter, prospective study that included 399 patients with HB from January 2015 to June 2020 was conducted. Patient demographics, treatment protocols, and other related information were collected. Cox regression models and Kaplan-Meier curve methods were used. RESULTS: The 4-year event-free survival (EFS) and overall survival (OS) were 76.9 and 93.5%, respectively. The 4-year EFS rates for the very-low-risk, low-risk, intermediate-risk, and high-risk groups were 100%, 91.6%, 81.7%, and 51.0%, respectively. The 4-year OS was 100%, 97.3%, 94.4%, and 86.8%, respectively. Cox regression analysis found that age, tumor rupture (R +), and extrahepatic tumor extension (E +) were independent prognostic factors. A total of 299 patients had complete remission, and 19 relapsed. Patients with declining alpha-fetoprotein (AFP) > 75% after the first two cycles of neoadjuvant chemotherapy had a better EFS and OS than those ≤ 75%. CONCLUSIONS: The survival outcome of HB children has dramatically improved since the implementation of CCCG-HB-2016 therapy. Age ≥ 8 years, R + , and E + were independent risk factors for prognosis. Patients with a declining AFP > 75% after the first two cycles of neoadjuvant chemotherapy had better EFS and OS.

RESUMEN

BACKGROUND: To identify radiomic features that can predict the pathological type of neuroblastic tumor in children. METHODS: Data on neuroblastic tumors in 104 children were retrospectively analyzed. There were 14 cases of ganglioneuroma, 24 cases of ganglioneuroblastoma, and 65 cases of neuroblastoma. Stratified sampling was used to randomly allocate the cases into the training and validation sets in a ratio of 3:1. The maximum relevance-minimum redundancy algorithm was used to identify the top 10 of two clinical features and 851 radiomic features in portal venous-phase contrast-enhanced computed tomography images. Least absolute shrinkage and selection operator regression was used to classify tumors in two binary steps: first as ganglioneuroma compared to the other two types, then as ganglioneuroblastoma compared to neuroblastoma. RESULTS: Based on 10 clinical-radiomic features, the classifier identified ganglioneuroma compared to the other two tumor types in the validation dataset with sensitivity of 100.0%, specificity of 81.8%, and an area under the receiver operating characteristic curve (AUC) of 0.875. The classifier identified ganglioneuroblastoma versus neuroblastoma with a sensitivity of 83.3%, a specificity of 87.5%, and an AUC of 0.854. The overall accuracy of the classifier across all three types of tumors was 80.8%. CONCLUSION: Radiomic features can help predict the pathological type of neuroblastic tumors in children.

RESUMEN

PURPOSE: To develop machine learning (ML) models to predict the surgical risk of children with pancreaticobiliary maljunction (PBM) and biliary dilatation. METHODS: The subjects of this study were 157 pediatric patients who underwent surgery for PBM with biliary dilatation between January, 2015 and August, 2022. Using preoperative data, four ML models were developed, including logistic regression (LR), random forest (RF), support vector machine classifier (SVC), and extreme gradient boosting (XGBoost). The performance of each model was assessed via the area under the receiver operator characteristic curve (AUC). Model interpretations were generated by Shapley Additive Explanations. A nomogram was used to validate the best-performing model. RESULTS: Sixty-eight patients (43.3%) were classified as the high-risk surgery group. The XGBoost model (AUC = 0.822) outperformed the LR (AUC = 0.798), RF (AUC = 0.802) and SVC (AUC = 0.804) models. In all four models, enhancement of the choledochal cystic wall and an abnormal position of the right hepatic artery were the two most important features. Moreover, the diameter of the choledochal cyst, bile duct variation, and serum amylase were selected as key predictive factors by all four models. CONCLUSIONS: Using preoperative data, the ML models, especially XGBoost, have the potential to predict the surgical risk of children with PBM and biliary dilatation. The nomogram may provide surgeons early warning to avoid intraoperative iatrogenic injury.

RESUMEN

PURPOSE: This study aimed to develop a prediction model to identify risk factors for post-operative acute pancreatitis (POAP) in children with pancreaticobiliary maljunction (PBM) by pre-operative analysis of patient variables. METHODS: Logistic regression (LR), support vector machine (SVM), and extreme gradient boosting (XGBoost) models were established using the prospectively collected databases of patients with PBM undergoing surgery which was reviewed in the period comprised between August 2015 and August 2022, at the Children's Hospital of Soochow University. Primarily, the area beneath the receiver-operating curves (AUC), accuracy, sensitivity, and specificity were used to evaluate the model performance. The model was finally validated using the nomogram and clinical impact curve. RESULTS: In total, 111 children with PBM met the inclusion criteria, and 21 children suffered POAP. In the validation dataset, LR models showed the highest performance. The risk nomogram and clinical effect curve demonstrated that the LR model was highly predictive. CONCLUSION: The prediction model based on the LR with a nomogram could be used to predict the risk of POAP in patients with PBM. Protein plugs, age, white blood cell count, and common bile duct diameter were the most relevant contributing factors to the models.

RESUMEN

BACKGROUND: To develop an end-to-end deep learning method for automated quantitative assessment of pediatric blunt hepatic trauma based on contrast-enhanced computed tomography (CT). METHODS: This retrospective study included 170 children with blunt hepatic trauma between May 1, 2015, and August 30, 2021, who had undergone contrast-enhanced CT. Both liver parenchyma and liver trauma regions were manually segmented from CT images. Two deep convolutional neural networks (CNNs) were trained on 118 cases between May 1, 2015, and December 31, 2019, for liver segmentation and liver trauma segmentation. Liver volume and trauma volume were automatically calculated based on the segmentation results, and the liver parenchymal disruption index (LPDI) was computed as the ratio of liver trauma volume to liver volume. The segmentation performance was tested on 52 cases between January 1, 2020, and August 30, 2021. Correlation analysis among the LPDI, trauma volume, and the American Association for the Surgery of Trauma (AAST) liver injury grade was performed using the Spearman rank correlation. The performance of severity assessment of pediatric blunt hepatic trauma based on the LPDI and trauma volume was evaluated using receiver operating characteristic (ROC) analysis. RESULTS: The Dice, precision, and recall of the developed deep learning framework were 94.75, 94.11, and 95.46% in segmenting the liver and 72.91, 72.40, and 76.80% in segmenting the trauma regions. The LPDI and trauma volume were significantly correlated with AAST grade (rho = 0.823 and rho = 0.831, respectively; p < 0.001 for both). The area under the ROC curve (AUC) values for the LPDI and trauma volume to distinguish between high-grade and low-grade pediatric blunt hepatic trauma were 0.942 (95% CI, 0.882-1.000) and 0.952 (95% CI, 0.895-1.000), respectively. CONCLUSIONS: The developed end-to-end deep learning method is able to automatically and accurately segment the liver and trauma regions from contrast-enhanced CT images. The automated LDPI and liver trauma volume can act as objective and quantitative indexes to supplement the current AAST grading of pediatric blunt hepatic trauma.

RESUMEN

With the advancement of prenatal examination technology, more and more fetus with ovarian masses are diagnosed. However, whether such children need intervention measures after delivery, there is no more unified diagnosis and treatment measures in the world. In this study, postnatal data and clinical outcome of fetal diagnosed with ovarian masses were analyzed. We also combined with relevant literature to explore the postpartum intervention measures and timing of such children. A total of 57 cases of abdominal masses from the reproductive system were included in the study. These children were diagnosed with ovarian masses after birth. We collected from 2012 to 2020, the prenatal examination revealed the presence of abdominal masses from the reproductive system, and diagnosis was confirmed by imaging examinations after childbirth. We counted the fetal period data of these children, compared the changes in the postnatal pathology and intervention measures. A total of 57 cases of ovarian masses were diagnosed prenatally, 1 case was lost to follow-up, and 56 cases were finally included in the study. After birth a total of 21 cases of ovarian masses were treated conservatively, of which 18 cases resolved spontaneously during the follow-up process, with an average follow-up period of 30.88 ±â€…18.16 weeks. There were statistically significant differences in the nature and the maximum diameter of the mass between the two groups receiving conservative treatment or surgical treatment after delivery (P < .05).Univariate and multivariate Logistic regression analysis showed that there were significant differences in the nature and diameter of the mass between two groups (P < .05). In addition, we divided the children undergoing postpartum surgery into a laparoscopic surgery group and a conventional open surgery group. Through data analysis, we found that there were statistically significant differences in the age of operation, operation time, and hospitalization days in the two groups of these children (P < .05). Children diagnosed with ovarian masses prenatally generally have a good prognosis. For these children, the treatment plan should be developed according to the child general condition. If child with ovarian mass is treated with surgery, the preservation of ovarian tissue should be emphasized regardless of the size, nature, and torsion of the mass.

RESUMEN

Cathepsin L (CTSL), a lysosomal acid cysteine protease, is found to play a critical role in chemosencitivity and tumor progression. However, the potential roles and molecular mechanisms of CTSL in chemoresistance in neuroblastoma (NB) are still unclear. In this study, the correlation between clinical characteristics, survival and CTSL expression were assessed in Versteeg dataset. The chemoresistant to cisplatin or doxorubicin was detected using CCK-8 assay. Western blot was employed to detect the expression of CTSL, multi-drug resistance proteins, autophagy-related proteins and apoptosis-related proteins in NB cells while knocking down CTSL. Lysosome staining was analyzed to access the expression levels of lysosomes in NB cells. The expression of apoptosis markers was analyzed with immunofluorescence. Various datasets were analyzed to find the potential protein related to CTSL. In addition, a subcutaneous tumor xenografts model in M-NSG mice was used to assess tumor response to CTSL inhibition in vivo. Based on the validation dataset (Versteeg), we confirmed that CTSL served as a prognostic marker for poor clinical outcome in NB patients. We further found that the expression level of CTSL was higher in SK-N-BE (2) cells than in IMR-32 cells. Knocking down CTSL reversed the chemoresistance in SK-N-BE (2) cells. Furthermore, combination of CTSL inhibition and chemotherapy potently blocked tumor growth in vivo. Mechanistically, CTSL promoted chemoresistance in NB cells by up-regulating multi-drug resistance protein ABCB1 and ABCG2, inhibiting the autophagy level and cell apoptpsis. Furthermore, we observed six datasets and found that Serglycin (SRGN) expression was positively associated with CTSL expresssion. CTSL could mediate chemoresistance by up-regulating SRGN expression in NB cells and SRGN expression was positively correlated with poor prognosis of NB patients. Taken together, our findings indicate that the CTSL promotes chemoresistance to cisplatin and doxorubicin by up-regulating the expression of multi-drug resistance proteins and inhibiting the autophagy level and cell apoptosis in NB cells. Thus, CTSL may be a therapeutic target for overcoming chemoresistant to cisplatin and doxorubicin in NB patients.

RESUMEN

Sepsis, a syndrome of acute organ dysfunction induced by various infections, could lead to a very high mortality in hospitals despite the development of advanced medical technologies. Herein, a type of two-phase releasing immune-stimulating composite is developed by mixing alginate (ALG) with muramyl dipeptide (MDP) and the nanoparticle formulation of monophosphoryl lipid A (MPLA), the latter two are immunomodulatory agents with different release rates from the formed ALG hydrogel. The obtained two phase-releasing composite could provide instantaneous sepsis protection by the rapid release of MDP to enhance the phagocytic and bactericidal function of macrophages. Later on, such composite could further offer long-term sepsis protection by the sustained release of MPLA to continuously activate the immune system, via up-regulating the production of various pro-inflammatory cytokines, promoting the polarization of macrophages, and increasing the percent of natural killer (NK) cells in the lesion after sepsis challenge. Mice survived from sepsis challenge after such treatment could resist a second infection. Notably, treatment with our composite could increase the mouse survival rate in a cecal ligation and puncture (CLP) induced polymicrobial sepsis model. This work provides an easy-translatable immune-stimulating formulation for effective protection against sepsis under various triggering causes. Our strategy may be promising for long-term broad prevention against various infections, and could potentially be used to protect medical workers under a new pandemic before a reliable vaccine is available.

RESUMEN

OBJECTIVE: To develop a mathematical model based on a combination of clinical and radiologic features (barium enema) for early diagnosis of short-segment Hirschsprung disease (SHSCR) in neonate. METHODS: The analysis included 54 neonates with biopsy-confirmed SHSCR (the cases) and 59 neonates undergoing barium enema for abdominal symptoms but no Hirschsprung disease (the control). Colon shape features extracted from barium enema images and clinical features were used to develop diagnostic models using support vector machine (SVM) and L2-regularized logistic regression (LR). The training cohort included 32 cases and 37 controls; testing cohort consisted 22 cases and 22 controls. Results were compared to interpretation by 2 radiologists. RESULTS: In the analysis by radiologists, 87 out of 113 cases were correctly classified. Six SHSCR cases were mis-classified into the non-HSCR group. In the remaining 20 cases, radiologists were unable to make a decision. Both the SVM and LR classifiers contained five clinical features and four shape features. The performance of the two classifiers was similar. The best model had 86.36% accuracy, 81.82% sensitivity, and 90.91% specificity. The AUC was 0.9132 for the best-performing SVM classifier and 0.9318 for the best-performing LR classifier. CONCLUSION: A combination of clinical features and colon shape features extracted from barium enemas can be used to improve early diagnosis of SHSCR in neonate.

RESUMEN

ABSTRACT: The reasons for readmission of children with Hirschsprung disease (HD) are multiple. The study aims to predict the relevant factors for the readmission of children with HD by collecting and analyzing the relevant data of the child's admission to the hospital at the time of surgery.A retrospective review was performed including all patients with surgical treatment of HD at our institution between the years of 2011 to 2020. Univariate and multivariate Logistic regression analysis were performed to obtain the independent risk factor for this study. The receiver operating characteristic curve (ROC) were used to assess the performance of derived models.A total of 162 patients were identified. The average presurgery weights were 6.93 ±â€Š1.78 kg in the readmission group and 8.38 ±â€Š3.17 kg in the non-readmission group. Six children were classified as a low-weight in the readmission group, and 11 children classified as low-weight in the non-readmission group. The length of the intestinal tube after resection was 25.25 ±â€Š15.21 cm in the readmission group, and 16.23 ±â€Š4.10 cm in the non-readmission group. The ROC for the prediction model of readmission after HD surgery (AUC = 0.811).In children undergoing the HD surgery, we showed preoperative low body weight and long intra-operative bowel resection significantly increase the probability of readmission due to complications.

RESUMEN

Accurate intraoperative tissue identification is critical to tumor surgery. However, conventional methods are labor- and time-intensive, which greatly delay the intraoperative decision-making. Herein, a matrix metalloproteinase (MMP)14-activated NIR-II nanoprobe (A&MMP@Ag2 S-AF7P) is presented for rapid unperturbed-tissue analysis for ex vivo and in vivo neuroblastoma diagnosis. A&MMP@Ag2 S-AF7P displays negligible fluorescence in normal tissues but is activated quickly by inhibiting the fluorescence resonance energy transfer (FRET) between Ag2 S QDs and A1094 mediated by MMP14 overexpressed in neuroblastoma; meanwhile, the exposure of the membrane penetrating peptide R9 (TAT-peptide) results in efficient internalization of nanoprobes in the cancer cells, providing superior tumor-to-normal (T/N) tissue ratio. Instant illumination of the lesion and well-defined tumor margins make the nanoprobes a suitable rapid diagnostic reagent for cancer surgical or tissue biopsy procedures.

RESUMEN

BACKGROUND: Enteric duplication is a congenital anomaly with varied clinical presentation that requires surgical resection for definitive treatment. Ileocaecal (IC) duplications are duplications located at the IC junction, not clearly identified in all the published series. The reported treatment is IC resection and ileocolic anastomosis. The purpose of our study was to present our experience in successfully resection of IC duplication by laparoscope, thus avoiding bowel resection in children. MATERIALS AND METHODS: A retrospective review was conducted of medical records of 15 patients with diagnosis of IC duplication, treated in the Department of Paediatric Surgery of our hospital, within the period from November 2013 to September 2018. RESULTS: Laparoscopic resection of IC duplication was successfully performed in all children without bowel resection. The operation time was 50-90 min (55 ΁ 10 min), and the post-operative hospitalization time was 5-7 days (average, 6 days). The 15 patients were followed up for 6-12 months (average, 10 months). No recurrence was found by abdominal ultrasound examination. The wound had small scars with good appearance of umbilicus. CONCLUSIONS: The laparoscopic approach allows for confirming the diagnosis and accurately defining the exact site of duplication, as well as for effective and safe treatment. Laparoscopic excision of IC duplication without bowel resection is a safe option and is worth promoting.

RESUMEN

Pancreaticobiliary maljunction (PBM) is associated with high risk of epithelial atypical growth and malignant transformation of the bile duct or gallbladder. However, overall changes in genetic expression have not been examined in children with PBM. Genome-wide expression was analyzed using peripheral blood samples from 10 children with PBM and 15 pediatric controls. Differentially expressed genes (DEGs) were identified using microarray. Bioinformatics analysis was conducted using Gene Ontology and KEGG analyses. The top 5 in the up-regulated genes in PBM were verified with qRT-PCR. Receiver operator characteristic curve analysis was conducted to evaluate the predictive accuracy of selected genes for PBM. The microarray experiments identified a total of 876 DEGs in PBM, among which 530 were up-regulated and the remaining 346 were down-regulated. Verification of the top 5 up-regulated genes (TYMS, MYBPC1, FUT1, XAGE2, and GREB1L) by qRT-PCR confirmed the up-regulation of MYBPC1 and FUT1. Receiver operating characteristic curve analysis suggested that FUT1 and MYBPC1 up-regulation could be used to predict PBM, with the area under the curve of 0.873 (95%CI=0.735-1.000) and 0.960 (95%CI=0.891-1.000), respectively. FUT1 and MYBPC1 were up-regulated in children with PBM, and could be used as potential biomarkers for PBM.

RESUMEN

RATIONALE: Hepatic hemangioma is the third most common pediatric tumor, and it is rare in the neonatal period. This case study presents a rare case of hepatic hemangioma found in a neonate. PATIENT CONCERNS: A girl who was 18 days of age with the emergence of jaundice and an abdominal mass was admitted for physical examination in the local department. DIAGNOSES: An ultrasound showed that the hepatic left lobe was about 9 cm × 7 cm × 7 cm in size. A CT scan indicated a giant hemangioma in the hepatic left lobe. MRI detected a lesion measuring about 92 mm × 71 mm × 68 mm. INTERVENTIONS: The patient was treated with propranolol 3.5 mg PO bid (body weight 3.8 kg) after 1 week of admission for 4 weeks, but the mass did not appear to regress. Surgery was then performed successfully. OUTCOMES: The patient recovered well without recurrence beyond one year. LESSONS: Imaging strategies and prenatal diagnosis are vital for the diagnosis of infantile hepatic hemangioma. Propranolol is effective in both cutaneous and hepatic multifocal and diffuse hemangioma. Adequate treatment time is necessary to cure the disease. The role of propranolol in massive hepatic hemangioma remains uncertain and needs further investigation.

RESUMEN

BACKGROUND AND OBJECTIVES: Pre-operative oral carbohydrate administration (POCA) is an important aspect of enhanced recovery after surgery and has many advantages. The objective of this study was to explore the safety and effect of pre-operative oral carbohydrate administration in infants. METHODS AND STUDY DESIGN: This was a prospective, multi-center, randomized study that randomly assigned 1200 infants into four groups. In the control group (group A), the infants were strictly restricted to 6-h preoperative fasting before anesthesia. In the enhanced recovery after surgery (ERAS) groups (groups B, C, and D), the infants were orally administered a 10% carbohydrate solution (10% glucose water; 5, 10, and 15 mL/kg, respectively) 2 h before anesthesia. Blood glucose, gastric residual volumes, crying ratios, and the length of hospital stay were observed. RESULTS: The blood glucose was significantly higher in groups B, C, and D than group A at the time of anesthesia. The gastric residual volume revealed virtually no residue in groups A, B, and C, but 15 infants in group D had a gastric residual volume. The crying ratio was significantly higher in group A. The length of hospital stay was not significantly different between the groups. CONCLUSIONS: POCA is well-tolerated in infants at a dose of 10 mL/kg.
