OBJECTIVEThis study was conducted to determine the value of the radiographic assessment scale in the diagnosis of neonatal necrotizing enterocolitis, and as measured by need for surgery.

METHODSA total of 61 neonates were classified into three groups according to the Bell's Staging Criteria: NECⅠ(n=25), NECⅡ(n=11) and NEC Ⅲ(n=25). Data on gestational age at birth, gender, birth weight, clinical manifestations, treatment and prognosis of the patients were collected. Radiographic assessment scale scores were evaluated by a pediatric radiologist.

RESULTSRadiographic assessment scale scores in the NECⅠ, NECⅡand NEC Ⅲ groups were 3.2±1.4, 5.3±1.7 and 8.9±1.7, respectively (P<0.05). The score was highest in the NEC Ⅲ group and lowest in the NECⅠgroup. Based on the different therapies, the NEC Ⅲ group was subdivided into operative and non-operative groups. Radiographic assessment scale scores in the two subgroups were 8.71±1.86 and 9.36±1.21 respectively (P>0.05). Radiographic assessment scale scores in neonates with intestinal perforation (9.6±1.1) were higher than in those with intestinal necrosis (6.8±1.8) (P<0.05). The majority of patients (80%) who underwent operation had radiographic assessment scale scores above 7. The effective rate was 96% and 64% respectively in the NECⅠand the NECⅡ groups. Of the children in the NECⅢ group, the cure rate was 71% in the operative group, and the effective rate was 9% in the non-operative group.

CONCLUSIONSThe radiographic assessment scale may be used to evaluate the severity of disease in neonates with NEC. Patients with a score on the radiographic assessment scale above 7 have indications for surgical intervention and have better short-term treatment response rates.

OBJECTIVETo study the risk factors for prognosis of neonatal necrotizing enterocolitis (NEC).

METHODSA retrospective analysis was performed on the clinical data of 82 neonates with NEC confirmed between January 2008 and October 2012. The possible prognostic factors in NEC were investigated by logistic regression analysis.

RESULTSIn the 82 cases of NEC, the cure rate decreased with the aggravation of condition (P<0.05). The preterm infants had a significantly higher incidence of NEC than the full-term infants at three or more weeks after birth (P=0.004). The univariate analysis showed that the prognosis of NEC was related to the factors such as sepsis, congenital heart disease, scleredema, peritonitis, metabolic acidosis, hyponatremia, leukocyte disorder, thrombocytopenia, elevated C-reactive protein, and severe abdominal X-ray abnormalities (P<0.05), and the further logistic regression analysis revealed that congenital heart disease, scleredema, and metabolic acidosis were main risk factors for the clinical outcome of NEC (P<0.05).

CONCLUSIONSThe onset time of NEC is correlated with gestational age in neonates. There are multiple prognostic factors in NEC; special attention should be paid to the patients with congenital heart disease, scleredema, and metabolic acidosis so that early intervention is performed to reduce mortality.

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of neonates, especially of preterm infants, with high morbidity and mortality. The surviving infants may have digestive tract and neurological sequelae. Therefore, the prevention and treatment of NEC are of great significance in improving survival rate and survival quality of neonates. To provide evidence-based recommendations for management of NEC, the guidelines were developed based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and the current domestic and overseas studies.

Necrotizing enterocolitis (NEC), with the main manifestations of bloody stool, abdominal distension, and vomiting, is one of the leading causes of death in neonates, and early identification and diagnosis are crucial for the prognosis of NEC. The emergence and development of machine learning has provided the potential for early, rapid, and accurate identification of this disease. This article summarizes the algorithms of machine learning recently used in NEC, analyzes the high-risk predictive factors revealed by these algorithms, evaluates the ability and characteristics of machine learning in the etiology, definition, and diagnosis of NEC, and discusses the challenges and prospects for the future application of machine learning in NEC.

Typhlitis is a necrotizing enterocolitis of the cecum, ascending colon and terminal ileum. Typhlits has been reported in the severely neutropenic patients and likely results from a combination of neutropenia and defects in the bowel mucosa related to cytotoxic chemotherapy. This disease is most common in patients with leukemia who have undergone intensive myeloablative chemotherapy. Presumptive diagnostic criteria for typhlitis include fever, abdominal pain and tenderness, and radiologic evidence of right-sided colonic inflammation in patients with neutropenia. Recently, this disease is also reported in patients with solid tumor due to increasing challenges of high dose chemotherapy. We report a case of typhlitis developed in the circumstance of neutropenia induced by chemotherapy in a patient with malignant testicular tumor.

Erythropoientin (Epo), a glycoprotein hormone, plays an important role in erythropoiesis and neuroprotection. Recently,Epo is also considered to have protective effects against hyperoxic lung injury, retinopathy of prematurity and neonatal necrotizing enterocolitis. Recombinant human erythropietin (rhEpo) as Epo gene cloning drug has been widely used in neonatal clinical practice.

The use of caffeine citrate for treatment of apnea in very low birth weight infants showed short-term and long-term benefits. A systematic review and meta-analysis of the literature was undertaken to document the effect providing caffeine early (0-2 days of life) compared to providing caffeine late (> or =3 days of life) in very low birth weight infants on several neonatal outcomes, including bronchopulmonary dysplasia (BPD). We searched MEDLINE, the EMBASE database, the Cochrane Library, and KoreaMed for this meta-analysis. The quality of the included studies was assessed using the Newcastle-Ottawa Scale and Jadad's scale. Studies were included if they examined the effect of the early use of caffeine compared with the late use of caffeine. Two reviewers screened the candidate articles and extracted the data from the full-text of all of the included studies. We included a total of 59,136 participants (range 58,997-59,136; variable in one study) from a total of 5 studies. The risk of death (odds ratio [OR], 0.902; 95% confidence interval [CI], 0.828 to 0.983; P=0.019), bronchopulmonary dysplasia (BPD) (OR, 0.507; 95% CI, 0.396 to 0.648; P<0.001), and BPD or death (OR, 0.526; 95% CI, 0.384 to 0.719; P<0.001) were lower in the early caffeine group. Early caffeine use was not associated with a risk of necrotizing enterocolitis (NEC) and NEC requiring surgery. This meta-analysis suggests that early caffeine use has beneficial effects on neonatal outcomes, including mortality and BPD, without increasing the risk of NEC.

OBJECTIVEThis study examined the effects of curcumin on intestinal histopathological changes, cyclooxygenase-2 (COX-2) expression, and tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) concentrations in neonatal rats with necrotizing enterocolitis (NEC), in order to investigate the effects of curcumin against NEC.

METHODSForty neonatal rats were randomly divided into four groups (n=10 each): normal control, solvent control, NEC model, and curcumin intervention. The general situations of rats were observed for 3 consecutive days, and the rats were then sacrificed on the 4th day. Intestinal tissues were obtained for examining the histopathological changes, COX-2 expression, and TNF-alpha and IL-10 concentrations.

RESULTSCurcumin treatment ameliorated the general situations and histopathological signs in rats with NEC. TNF-alpha and IL-10 concentrations in the NEC model and the curcumin intervention groups increased significantly compared with those in the normal and solvent control groups (p<0.05). The concentration of TNF-alpha decreased (p<0.05), while the concentration of IL-10 increased significantly in the curcumin intervention group in comparison with the NEC model group (p<0.05). Immunohistochemistry results indicated that the positive expression of COX-2 in the curcumin intervention group was significantly lower than that in the NEC model group.

CONCLUSIONSCurcumin has protective effects against NEC in neonatal rats, possibly through inhibiting COX-2 expression, reducing TNF-alpha content, and increasing IL-10 content.

Typhlitis is a life threatening necrotizing enterocolitis of the cecum, ascending colon and terminal ileum seen in severely neutropenic patients, however its pathogenesis is not identified up to this time.The incidence of typhlitis in leukemic patient is 10~12%, estimated by postmortem examination, and 46% in induction chemotherapy of leukemia. Recently, entity incidence is more high due to increasing challenges to high dose chemotherapy in solid tumors.We experienced four cases of typhlitis, one was developed in the circumstance of neutropenia induced by induction chemotherapy for acute myelocytic leukemia and others in neutropnia due to primary diseases without chemotherapy, ig, chronic myelocytic leukemia, acute lymphocytic leukemia, myelodysplastic syndrome.All cases were treated with high dose broad spectrum antibiotics in early phase of disease and its outcome was good, so that, early diagnosis of typhlitis is essential, then prompt treatment with high dose antibiotics and intravenous fluid before onset of transmural necrosis is associated with lower morbidity and mortality than surgical resection.

OBJECTIVEIntravenous indomethacin is the conventional treatment for patent ductus arteriosus (PDA) in preterm infants; however its use is associated with various side effects such as oliguria, gastrointestinal bleeding and reduction of cerebral perfusion. Intravenous ibuprofen has recently been used to treat PDA in preterm infants without reducing cerebral blood flow or affecting intestinal or renal hemodynamics. Intravenous forms of indomethacin and ibuprofen are not available in Iran. This study aimed to examine and compare the efficacy and safety of oral ibuprofen and oral indomethacin for the treatment of PDA in preterm infants.

METHODSThirty-six infants (gestational age less than 34 weeks) who had echocardiographically confirmed PDA were enrolled in this study. The patients were randomly administered with three oral doses of either indomethacin (0.2 mg/kg, at an interval of 24 hrs) or ibuprofen (a first dose of 10 mg/kg, followed at an interval of 24 hrs by two doses of 5 mg/kg each) (n=18 each group). The rate of ductal closure, side effects, complications, and the infants' clinical course were recorded.

RESULTSThe ductus was closed in all of 18 patients (100%) in the ibuprofen group and in 15 (83.3%) patients in the indomethacin group (P > 0.05). There were no significant differences in the levels of serum blood urea nitrogen and creatinine between the two groups before and after treatment. Necrotizing enterocolitis (NEC) occurred in 3 patients in the indomethacin group and none in the ibuprofen group (P < 0.05). The survival rate at 1 month after treatment was 94% (17/18) in both groups. One infant in the ibuprofen group died from sepsis and one in the indomethacin group died as a result of NEC.

CONCLUSIONSOral ibuprofen is as effective as oral indomethacin for the treatment of PDA in preterm infants. Oral ibuprofen therapy is associated with a lower incidence of NEC.
