    Objective This study aimed to investigate the relationship between maternal hypertensive disease and other risk factors and the neonatal development of necrotizing enterocolitis (NEC). Methods This was a retrospective case control study of infants with NEC from 2008 to 2012. The primary exposure of interest was maternal hypertensive disease, which has been hypothesized to put infants at risk for NEC. Other variables collected included demographics, pregnancy complications, medications, and neonatal hospital course. Data was abstracted from medical records. Results 28 cases of singleton neonates with NEC and 81 matched controls were identified and analyzed. There was no significant difference in the primary outcome. Fetuses with an antenatal diagnosis of growth restriction were more likely to develop NEC (p=0.008). Infants with NEC had lower median birth weight than infants without NEC (p=0.009). Infants with NEC had more late-onset sepsis (p=0.01) and mortality before discharge (p=0.001). Conclusions The factors identified by this case-control study that increased the risk of neonatal NEC included intrauterine growth restriction and lower neonatal birth weight. The primary exposure, hypertensive disease, did not show a significantly increased risk of neonatal NEC, however there was a nearly two-fold difference observed. Our study was underpowered to detect the observed difference. PMID:25162307

    Full Text Available Phani Kiran Yajamanyam,1 Shree Vishna Rasiah,1 Andrew K Ewer1,2 1Neonatal Unit, Birmingham Women's Hospital NHS Foundation Trust, 2School of Clinical and Experimental Medicine, University of Birmingham, Birmingham, UK Abstract: Necrotizing enterocolitis is the most common gastrointestinal emergency in neonates, particularly in those born very preterm. It is a leading cause of morbidity and mortality, especially in extremely low birth weight infants. Despite extensive research, the pathophysiology of necrotizing enterocolitis remains unclear and therapeutic options are limited. Multiple risk factors have been reported, but most are associated with prematurity and its complications. This makes management very challenging in vulnerable preterm infants. In this review, we focus on the risk factors and some of the current research in this area, particularly studies aimed at early detection and potential preventive measures for this potentially lethal condition.

    Full Text Available Purpose: Necrotizing enterocolitis is one of the important problems of premature infants. The incidence is about 1-5% in infants followed in neonatal care units and inversely related to gestational age and birth weight. Materials and Methods: In this study, 31 infants with necrotizing enterocolitis and 31 infants with similar gestational age and birth weight as control group hospitalized in Cukurova University Neonatal Care Unit between 1 January 2001-31 January 2004 were evaluated. Results: The incidence of necrotizing enterocolitis in this period was 1.4 (31/2214 admission. Mean gestational age was 30.5  3.2 weeks (25-36, mean birth weight was 1331  384 (730-2150 grams while 71% was younger than 32 gestational weeks and 67.7% was under 1500 grams. The signs of NEC were detected at a mean of 11.2  10. (2-38 days. Twenty-six (83.9% were being fed at the time of the necrotizing enterocolitis signs appeared. According to the Walsh and Kliegman classification, 19 (61.3% infants were in stage 1 (17 were 1a, 2 were 1b; 3 (9.6% infants were in stage 2a, 9 (%29.1 infants were in stage 3 (7 were in 3b. Blood culture was positive in 7 (%22.6 infants with predominance of gram negative microorganisms (5 infants. Eleven (%35.5 infants were exitus, 12 were discharged. Hypoxia, respiratory distress syndrome, intraventricular hemorrhage and umbilical catheterization were significant risk factors in necrotizing enterocolitis . Thrombocytopenia, leucopenia and high C-reactive protein levels were significantly high in necrotizing enterocolitis group. Breast feeding is significantly high in control group. Conclusion: Necrotizing enterocolitis, is a leading cause of morbidity and mortality in neonatal intensive care units. Early breast feeding with small amounts, increasing amount of milk slowly, antenatal steroids, caring hygiene rules can prevent the development of it. [Cukurova Med J 2013; 38(4.000: 642-647

    Neonatal sepsis and necrotizing enterocolitis (NEC) are two most important neonatal problems in nursery which constitute the bulk of neonatal mortality and morbidity. Inflammatory mediators secondary to sepsis and NEC increases morbidity, by affecting various system of body like lung, brain and eye, thus causing long term implications. Lactoferrin (LF) is a component of breast milk and multiple actions that includes antimicrobial, antiviral, anti-fungal and anti-cancer and various other actions. Few studies have been completed and a number of them are in progress for evaluation of efficacy and safety of LF in the prevention of neonatal sepsis and NEC in field of neonatology. In future, LF prophylaxis and therapy may have a significant impact in improving clinical outcomes of vulnerable preterm neonates. This review analyse the role of lactoferrin in prevention of neonatal sepsis and NEC, with emphasis on mechanism of action, recent studies and current studies going on around the globe.

    on the nutritional, microbial and immunological interactions during the early feeding-induced mucosal dysfunction and later NEC development. We show that introduction of suboptimal enteral formula diets, coupled with parenteral nutrition, predispose to disease, while advancing amounts of mother's milk from birth...... (particularly colostrum) protects against disease. Hence, the transition from parenteral to enteral nutrition shortly after birth plays a pivotal role to secure gut growth, digestive maturation and an appropriate response to bacterial colonization in the sensitive gut of preterm neonates.......The gastrointestinal inflammatory disorder, necrotizing enterocolitis (NEC), is among the most serious diseases for preterm neonates. Nutritional, microbiological and immunological dysfunctions all play a role in disease progression but the relationship among these determinants is not understood...

    Necrotizing enterocolitis (NEC), the devastating enteric process of premature neonates, is marked by severe intravascular abnormalities and disseminated intravascular coagulation. Treatment to date remains historical and continues to be merely supportive without attempts to ameliorate progress within the inflammatory or coagulation cascades. Antithrombin III (ATIII) supplementation has been shown to favorably alter the process of disseminated intravascular coagulation and sepsis in adults. However, no reported use of this treatment exists in neonates. Therefore, we analyze the efficacy of our recent experience with ATIII replacement therapy in neonates with NEC. Age and diseased-matched controls with NEC were identified before the introduction of ATIII in our institution and compared against neonates with NEC undergoing ATIII replacement for diminished ATIII levels. Data collected included demographics, course of treatment parameters, and outcomes. Course of treatment parameters included hemoglobin, platelet count, prothrombin time, and partial thromboplastin time over the first 10 consecutive days of treatment. Outcome variables included packed red blood cell, platelet, fresh frozen plasma, and cryoprecipitate transfusions, as well as transfusion cost, length of stay, and survival. Over a 5-year period, 19 neonates with NEC received ATIII and were compared to 17 historical controls. Treatment hematologic profiles were not worsened in the ATIII-treated patients. The control patients received less overall transfusions and had a shorter length of stay. Antithrombin III appears to be safe in neonates with NEC, and its impact on reversing intravascular pathology in these patients warrants more thorough investigation.

  9. Dextran sodium sulfate (DSS induces necrotizing enterocolitis-like lesions in neonatal mice.

    Full Text Available Necrotizing enterocolitis (NEC is an inflammatory bowel disease of preterm human newborns with yet unresolved etiology. An established neonatal murine model for NEC employs oral administration of lipopolysaccharides (LPS combined with hypoxia/hypothermia. In adult mice, feeding dextran sodium sulfate (DSS represents a well-established model for experimental inflammatory bowel disease. Here we investigated the effect of DSS administration on the neonatal murine intestine in comparison with the established NEC model.3-day-old C57BL/6J mice were either fed formula containing DSS or LPS. LPS treated animals were additionally stressed by hypoxia/hypothermia twice daily. After 72 h, mice were euthanized, their intestinal tissue harvested and analyzed by histology, qRT-PCR and flow cytometry. For comparison, adult C57BL/6J mice were fed with DSS for 8 days and examined likewise. Untreated, age matched animals served as controls.Adult mice treated with DSS exhibited colonic inflammation with significantly increased Cxcl2 mRNA expression. In contrast, tissue inflammation in neonatal mice treated with DSS or LPS plus hypoxia/hypothermia was present in colon and small intestine as well. Comparative analysis of neonatal mice revealed a significantly increased lesion size and intestinal Cxcl2 mRNA expression after DSS exposure. Whereas LPS administration mainly induced local neutrophil recruitment, DSS treated animals displayed increased monocytes/macrophages infiltration.Our study demonstrates the potential of DSS to induce NEC-like lesions accompanied by a significant humoral and cellular immune response in the small and large intestine of neonatal mice. The new model therefore represents a good alternative to LPS plus hypoxia/hypothermia administration requiring no additional physical stress.

    The ability of external imaging to demonstrate intestinal infarction in neonatal necrotizing enterocolitis (NEC) was prospectively evaluated. The radiopharmaceutical technetium--99m diphosphonate was injected intravenously and the patients subsequently underwent abdominal scanning. Clinical patient care and interpretation of the images were entirely independent throughout the study. Of 33 studies, 7 were positive, 4 were suspicious, and 22 were negative. One false positive study detected ischemia without transmural infarction. The second false positive scan occurred postoperatively and was due to misinterpretation of the hyperactivity along the surgical incision. None of the suspicious cases had damaged bowel. The two false negative studies clearly failed to demonstrate frank intestinal necrosis. The presence of very small areas of infarction, errors in technical settings, subjective interpretation of scans and delayed clearance of the radionuclide in a critically ill neonate may all limit the accuracy of external abdominal scanning. However, in spite of an error rate of 12%, it is likely that this technique will enhance the present clinical, laboratory, and radiologic parameters of patient management in NEC

  11. Probiotics and necrotizing enterocolitis.

    Probiotics for the prevention of necrotizing enterocolitis have attracted a huge interest. Combined data from heterogeneous randomised controlled trials suggest that probiotics may decrease the incidence of NEC. However, the individual studies use a variety of probiotic products, and the group at greatest risk of NEC, i.e., those with a birth weight of less than 1000 g, is relatively under-represented in these trials so we do not have adequate evidence of either efficacy or safety to recommend universal prophylactic administration of probiotics to premature infants. These problems have polarized neonatologists, with some taking the view that it is unethical not to universally administer probiotics to premature infants, whereas others regard the meta-analyses as flawed and that there is insufficient evidence to recommend routine probiotic administration. Another problem is that the mechanism by which probiotics might act is not clear, although some experimental evidence is starting to accumulate. This may allow development of surrogate endpoints of effectiveness, refinement of probiotic regimes, or even development of pharmacological agents that may act through the same mechanism. Hence, although routine probiotic administration is controversial, studies of probiotic effects may ultimately lead us to effective means to prevent this devastating disease.

    Necrotizing enterocolitis (NEC) is a major cause of neonatal morbidity and mortality. Preventive and therapeutic research, surveillance, and quality improvement initiatives are hindered by variations in case definitions. To develop a gestational age (GA)-specific case definition for NEC. We conducted a prospective 34-month population study using clinician-recorded findings from the UK National Neonatal Research Database between December 2011 and September 2014 across all 163 neonatal units in England. We split study data into model development and validation data sets and categorized GA into groups (group 1, less than 26 weeks' GA; group 2, 26 to less than 30 weeks' GA; group 3, 30 to less than 37 weeks' GA; group 4, 37 or more weeks' GA). We entered GA, birth weight z score, and clinical and abdominal radiography findings as candidate variables in a logistic regression model, performed model fitting 1000 times, averaged the predictions, and used estimates from the fitted model to develop an ordinal NEC score and cut points to develop a dichotomous case definition based on the highest area under the receiver operating characteristic curves [AUCs] and positive predictive values [PPVs]. Abdominal radiography performed to investigate clinical concerns. Ordinal NEC likelihood score, dichotomous case definition, and GA-specific probability plots. Of the 3866 infants, the mean (SD) birth weight was 2049.1 (1941.7) g and mean (SD) GA was 32 (5) weeks; 2032 of 3663 (55.5%) were male. The total included 2978 infants (77.0%) without NEC and 888 (23.0%) with NEC. Infants with NEC in group 1 were less likely to present with pneumatosis (31.1% vs 47.2%; P = .01), blood in stool (11.8% vs 29.6%; P definition were 2 or greater for infants in groups 1 and 2, 3 or greater for infants in group 3, and 4 or greater for infants in group 4. The ordinal NEC score and dichotomous case definition discriminated well between infants with (AUC, 87%) and without (AUC, 80%) NEC. The case

    The purpose of the present study is to compare risk factors of necrotizing enterocolitis (NEC) between two group: group A, newborns with the disease and group B, newborns with other diseases different from NEC, in order to know if these risk factors are more frequent or not in the first group. We assessed the clinical records of all the patients hospitalized in the Neonatal Intensive Care Unit and Neonatology Service of the La Raza General Hospital between 1987 and 1991 with the diagnosis of NEC. They were compared with 65 clinical records chosen at random of patients hospitalized in the same Unit with other diagnosis at the same time, and who were discharged by improvement or deceased. In all of them were look for known risk factors for NEC generally accepted such as: prematurity, neonatal asphyxia, poliglobulia, cyanotic congenital heart disease, patent ductus arteriosus, respiratory distress syndrome, catheterization of umbilical vessels, early feeding of elevated formula increases, exchange exchange transfusion, hypoxic ischemic encephalopathy, infection, etc. Just 25 records of the possible 50 with the diagnosis of NEC full filled inclusion criteria. There were no statistically significant difference in weight, sex, mortality and known risk factors of NEC between both groups. Were concluded that NEC is a disease of unknown etiology that should be studied more thoroughly. The known risk factors must be avoided because the patient susceptibility probably play an important role.

    To determine if intestinal alkaline phosphatase (IAP) decreases intestinal injury resulting from experimentally induced necrotizing enterocolitis (NEC). We hypothesized that IAP administration prevents the initial development of NEC related intestinal inflammation. Pre- and full-term newborn Sprague-Dawley rat pups were sacrificed on day 1 of life. Pre-term pups were exposed to intermittent hypoxia and formula containing LPS to induce NEC. Select NEC pups were given 40, 4 or 0.4 units/kg of bovine IAP (NEC+IAP40u, IAP4u or IAP0.4u) enterally, once daily. Ileal sections were evaluated by real-time PCR (qRT-PCR) for IAP, iNOS, IL-1β, IL-6, and TNF-α mRNA and immunofluorescence for 3-nitrotyrosine (3-NT). Experimentally induced NEC decreased IAP mRNA expression by 66% (p ≤ 0.001). IAP supplementation increased IAP mRNA expression to control. Supplemental enteral IAP decreased nitrosative stress as measured by iNOS mRNA expression and 3-NT staining in the NEC stressed pups (p ≤ 0.01), as well as decreased intestinal TNF-α mRNA expression. In addition, IAP decreased LSP translocation into the serum in the treated pups. We conclude that enterally administered IAP prevents NEC-related intestinal injury and inflammation. Enteral IAP may prove a useful strategy in the prevention of NEC in preterm neonates. Copyright © 2013 Elsevier Inc. All rights reserved.

    Necrotizing enterocolitis (NEC) is one of the most common acute and fatal gastrointestinal emergency in very low birth weight (VLBW) preterm neonates with mortality range from 15 to 30%. NEC is likely due to multifactorial process such as oxidative injury, ischemic necrosis, and over-reactive inflammatory response to intestinal microbes. To evaluate the role of amino acid supplementation for reduction of neonatal NEC in preterm neonates. The literature search was done for various randomized control trial (RCT) by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Scopus, Index Copernicus, African Index Medicus (AIM), Thomson Reuters (ESCI), Chemical Abstracts Service (CAS) and other database. This review included 15 RCTs that fulfilled inclusion criteria. The total neonates enrolled in these different RCT are 3424 (amino acid group 1711 and control 1713). Almost all participating neonates were of VLBW or extremely low birth weight (ELBW). In two trials, birth weight was between 1500-2000 grams. The intervention was started within first few days after birth and continued up to 30th day of postnatal age in most of the trials. In two trials, intervention was continued up to 120th day of postnatal age. Arginine, glutamine and N-acetyl cysteine (NAC) were used at the dose of 1.5 mol/kg/day (261 mg/kg/day), 0.3 grams/kg/day and 16-32 mg/kg/day, respectively. Role of amino acid in the prevention of neonatal NEC is not exclusively supported by the current evidence. Only three studies were able to show reduction in the incidence of NEC with amino acid supplementation (arginine, glutamine), and the remaining studies did not report any positive effect. Amino acid supplementation was not associated with significant reduction in mortality due to any causes. However, arginine supplementation was associated with significant reduction in mortality due to NEC. Two studies on glutamine were reported significant reduction in

    Supplementation of intestinal alkaline phosphatase (IAP), an endogenous protein expressed in the intestines, decreases the severity of necrotizing enterocolitis (NEC)-associated intestinal injury and permeability. We hypothesized that IAP administration is protective in a dose-dependent manner of the inflammatory response in a neonatal rat model. Pre- and full-term newborn Sprague-Dawley rat pups were sacrificed on day of life 3. Control pups were vaginally delivered and dam fed. Preterm pups were delivered via cesarean section and exposed to intermittent hypoxia and formula feeds containing lipopolysaccharide (NEC) with and without IAP. Three different standardized doses were administered to a group of pups treated with 40, 4, and 0.4U/kg of bovine IAP (NEC+IAP40, IAP4, or IAP0.4U). Reverse transcription-real-time polymerase chain reaction (RT-PCR) for inducible nitric oxide synthase (iNOS) and tumor necrosis factor (TNF)-α on liver and lung tissues and serum cytokine analysis for interleukin (IL)-1β, IL-6, IL-10, and TNF-α were performed. Data were analyzed by Kruskal-Wallis and Mann-Whitney tests, expressed as mean±standard error of the mean and P≤0.05 considered significant. Levels of cytokines IL-1β, IL-6, and TNF-α increased significantly in NEC versus control, returning to control levels with increasing doses of supplemental enteral IAP. Hepatic and pulmonary TNF-α and iNOS messenger ribonucleic acid expressions increased in NEC, and the remaining elevated despite IAP supplementation. Proinflammatory cytokine expression is increased systemically with intestinal NEC injury. Administration of IAP significantly reduces systemic proinflammatory cytokine expression in a dose-dependent manner. Early supplemental enteral IAP may reduce NEC-related injury and be useful for reducing effects caused by a proinflammatory cascade. Copyright © 2012 Elsevier Inc. All rights reserved.

    2017-11-01

    In neonates requiring operation for necrotizing enterocolitis (NEC), the complications due to enterostomy (ES) and the need for another operation to restore continuity have prompted several surgeons to employ primary anastomosis (PA) after resection as the operative strategy of choice. Our objective was to compare primary anastomosis to stoma formation in this population using systematic review and meta-analysis. Publications describing both interventions were identified by searching multiple databases. Appropriate studies that reported outcomes after PA and ES for NEC were included for analysis that was performed using the MedCalc3000 software. Results are reported as odds ratios (OR, 95% CI). No randomized trials were identified. Twelve studies were included for the final analysis. Neonates who underwent PA were associated with significantly less risk of mortality when compared to those who underwent ES (OR 0.34, 95% CI 0.17-0.68, p 0.002), possibly due to differences in severity of NEC. Although the types of complications in these groups were different, there was no significant difference in risk of complication (OR 0.86, 0.55-1.33, p 0.50). In neonates undergoing an operation for severe NEC, there is no significant difference in the risk of complications between primary anastomosis and enterostomy. A definitive suggestion cannot be made regarding the choice of one operative strategy over another.

    Full Text Available The incidence of necrotizing enterocolitis (NEC and mortality rate associated with this disease are not decreasing despite more than three decades of intensive research investigation and advances in neonatal intensive care. Although the etiology of NEC is not clearly elucidated, the most accepted hypothesis at present is that enteral feeding in the presence of intestinal hypoxia-ischemia-reperfusion, and colonization with pathogens provokes an inappropriately accentuated inflammatory response by the immature intestinal epithelial cells of the preterm neonate. However, delayed colonization of commensal flora with dysbiotic flora with a predominance of pathologic microorganisms plays a fundamental role in the pathogenesis of NEC. Recent studies have further identified that NEC infants have less diverse flora compared to age-matched controls without NEC. Increased gastric residual volume may be an early sign of NEC. An absolute neutrophil count of <1.5 × 109/L and platelets below 100 × 109/L are associated with an increased risk for mortality and gastrointestinal morbidity. Nonspecific supportive medical management should be initiated promptly. Sudden changes in vital signs such as tachycardia or impending shock may indicate perforation. A recent meta-analysis investigating using probiotics for prevention of NEC with a total of 2176 preterm very low birth weight infants found a success rate of just 1/25. Careful monitoring of the residual volume, and of serious changes in hemograms and vital signs may help in early diagnosis and prediction of when to perform medical or early surgical intervention. In term of prevention, administration of oral probiotics containing Bifidobacterium and Lactobacillus is a simple and safe method that attempts to early establish of commensal flora balance to inhibit pathogenic flora and an inflammatory response.

    Despite extensive research and improvements in the field of neonatal care, the morbidity and mortality associated with necrotizing enterocolitis (NEC) have remained unchanged over the past three decades. Early detection of ischemia and necrotic bowel is vital in improving morbidity and mortality associated with NEC; however, strategies for predicting and preventing NEC are lacking. Contrast-enhanced ultrasound (CEUS) and near-infrared spectroscopy (NIRS) are novel techniques in pediatrics that have been proven as safe modalities. CEUS has benefits over conventional ultrasound (US) by its improved real-time evaluation of the micro- and macrovascularities of normally and abnormally perfused tissue. US has been implemented as a useful adjunct to X-ray for earlier evaluation of NEC. NIRS is another noninvasive technique that has shown promise in improving early detection of NEC. The purpose of this article is to review the current understanding of changes in bowel perfusion in NEC, discuss the accuracy of abdominal US in detecting NEC, and explain how the use of CEUS and NIRS will enhance the precise and early detection of altered/pathological bowel wall perfusion in the initial development and course of NEC.

    Full Text Available Necrotizing enterocolitis (NEC is among the most common and devastating diseases in neonates and, despite the significant advances in neonatal care and clinical and basic science investigations, its etiology remains incompletely understood, specific treatment strategies are lacking, and morbidity and mortality from this disease remain high. Recent improvements in the pathophysiology of NEC may have therapeutic consequences. Toll-like receptors and intestinal microflora play an increasing role in the pathogenesis of NEC. Pharmacologic inhibition of TLR signaling, the use of novel nutritional strategies, and microflora modulation may represent novel promising approaches to the prevention and treatment of NEC. This review focuses on current and future therapeutic perspectives, starting from the recent acquisitions in the pathogenic mechanisms of NEC. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Full Text Available BACKGROUND: The etiology of necrotizing enterocolitis (NEC results from a combination of several risk factors that act synergistically and occurs in the same circumstances as those which lead to innate immunity activation. Pattern recognition molecules could be an important player in the initiation of an exaggerated inflammatory response leading to intestinal injury in NEC. METHODOLOGY/PRINCIPAL FINDINGS: We specifically evaluated intestinal epithelial cell (IEC expression of Toll-like receptor 2 (TLR-2, TLR-4, NOD2 and phosphorylated NF-kappaB (pNF-kappaB after mucosal injury in a rat model of NEC induced by prematurity, systemic hypoxia, and a rich protein formula. In the control group (group 1, neonatal rats were full-term and breast-fed; in the experimental groups, rat pups were preterm at day 21 of gestation and rat-milk fed (group 2 or hand-gavaged with a protein rich formula after a hypoxia-reoxygenation procedure (group 3. Morphological mucosal changes in the small bowel were scored on hematoxylin- and eosin-stained sections. Immunohistochemistry was performed on frozen tissue sections using anti TLR-2 and active pNF-kappaB p65 antibodies. Real-time RT-PCR was performed to assess mRNA expression of NOD2, TLR-2 and TLR-4. Proliferation and apoptosis were studied in paraffin sections using anti Ki-67 and caspase-3 antibodies, respectively. The combination of immaturity, protein rich formula and a hypoxia-reoxygenation procedure induces pathological mucosal damage consistent with NEC. There was an overexpression of TLR-2, and pNF-kappaB in IECs that was correlated with the severity of mucosal damage, together with an increase of apoptotic IECs and markedly impaired proliferation. In addition, these immunological alterations appeared before severe mucosal damage. TLR-2 mRNA were also increased in NEC together with TLR-4 mRNA using real-time RT-PCR whereas NOD2 expression was unchanged. CONCLUSIONS/SIGNIFICANCE: These results show that this

    We aimed at identifying potential bacterial factors linking clostridia with necrotizing enterocolitis (NEC). We compared the phenotypic traits, stress responses, cellular cytotoxicity, and inflammatory capabilities of the largest collection of Clostridium butyricum and Clostridium neonatale strains isolated from fecal samples of NEC preterm neonates (PN) and control PNs. When strain characteristics were used as explanatory variables, a statistical discriminant analysis allowed the separation of NEC and control strains into separate groups. Strains isolated from NEC PN were characterized by a higher viability at 30°C ( P = 0.03) and higher aerotolerance ( P = 0.01), suggesting that NEC strains may have a competitive and/or survival advantage in the environmental gastrointestinal tract conditions of NEC PN. Heat-treated NEC bacteria induced higher production of interleukin-8 in Caco-2 cells ( P = 0.03), suggesting proinflammatory activity. In vitro , bacteria, bacterial components, and fecal filtrates showed variable cytotoxic effects affecting the cellular network and/or cell viability, without specific association with NEC or control samples. Altogether, our data support the existence of a specific clostridial strain signature associated with NEC. IMPORTANCE Clostridia are part of the commensal microbiota in preterm neonates (PN). However, microbiota analyses by culture and metagenomics have linked necrotizing enterocolitis (NEC) and intestinal colonization with clostridial species. Nevertheless, little is known about the specific characteristics that may be shared by clostridia associated with NEC compared to commensal clostridia. Therefore, our goal was to identify specific bacterial factors linking clostridial strains with NEC. We report the existence of a specific bacterial signature associated with NEC and propose that activation of the innate immune response may be a unifying causative mechanism for the development of NEC independent of a specific pathogenic

    Necrotizing enterocolitis (NEC) is one of the most serious disorders of gastrointestinal tract during neonatal period. Early diagnosis and adequate treatment are essential in the presence of clinical suspicion of NEC. Plain abdominal radiography is currently the modality of choice for initial evaluation of gastrointestinal tract in neonates. However, when the diagnosis is uncertain, abdominal ultrasound with bowel assessment might be an important complementary examination. The aim of the study was to evaluate usefulness of ultrasound in the diagnosis of NEC and its value for implementation of proper treatment. The data of nine neonates diagnosed with NEC, hospitalized at the Provincial Hospital No. 2 in Rzeszow in the period from September 2009 to April 2013 was retrospectively analyzed. Apart from abdominal radiography, abdominal ultrasound with bowel assessment was performed in all nine cases. Imaging findings, epidemiological data, coexisting risk factors and disease course were assessed. Most children in the group were preterm neonates. Findings in plain abdominal radiography were normal or nonspecific. A wider spectrum of findings was demonstrated in all ultrasound examinations and intestinal pneumatosis, a pathognomonic sign for NEC, was more frequently noted than in plain abdominal x-ray. Most children were treated by surgical intervention with resection of necrotic bowel loops and in more than half of the cases location of changes identified during surgery was concordant with ultrasonographic findings. Abdominal ultrasound examination might be helpful in the diagnosis of NEC, especially when plain abdominal radiography findings do not correlate with clinical symptoms. However, abdominal radiography is still considered the modality of choice. The range of morphological changes detectable on ultrasound examination is much wider than in plain abdominal radiography. Ultrasound examination allows for more accurate assessment of changes within intestines and

    Full Text Available Necrotizing enterocolitis (NEC remains a leading cause of morbidity and mortality, affecting primarily preterm neonates. The pathogenesis of this intestinal disease appears to be linked to the disruption or delay of bacterial colonization, termed gut dysbiosis. Intestinal immaturity, antibiotic use and hospital microbial environment are the main triggers of this pathological process. Conversely, gut symbiosis is made possible by the presence of beneficial and commensal bacterial species that protect the immature gut from opportunistic pathogens overgrowth and inflammation. Herein, we review the relationships between gut microbiota and NEC in preterm neonates. We also discuss the role of specific microorganisms belonging to the commensal microbiota, highlighting the possibility for a toxigenic mechanism involved in NEC pathogenesis. We conclude on the importance of interventions aimed at providing or restoring beneficial bacteria populations, in view to efficiently preventing or treating NEC.

    Necrotizing enterocolitis (NEC) is the leading cause of death from gastrointestinal disease in premature infants and develops partly from an exaggerated intestinal epithelial immune response to indigenous microbes. There has been interest in administering probiotic bacteria to reduce NEC severity, yet concerns exist regarding infection risk. Mechanisms of probiotic activity in NEC are unknown although activation of the microbial DNA receptor Toll-like receptor-9 (TLR9) has been postulated. We now hypothesize that the Gram-positive bacterium Lactobacillus rhamnosus HN001 can attenuate NEC in small and large animal models, that its microbial DNA is sufficient for its protective effects, and that protection requires activation of the Toll-like receptor 9 (TLR9). We now show that oral administration of live or UV-inactivated Lactobacillus rhamnosus HN001 attenuates NEC severity in newborn mice and premature piglets, as manifest by reduced histology score, attenuation of mucosal cytokine response, and improved gross morphology. TLR9 was required for Lactobacillus rhamnosus-mediated protection against NEC in mice, as the selective decrease of TLR9 from the intestinal epithelium reversed its protective effects. Strikingly, DNA of Lactobacillus rhamnosus HN001 reduced the extent of proinflammatory signaling in cultured enterocytes and in samples of resected human ileum ex vivo, suggesting the therapeutic potential of this probiotic in clinical NEC. Taken together, these findings illustrate that Lactobacillus rhamnosus HN001 is an effective probiotic for NEC via activation of the innate immune receptor TLR9 and that Lactobacillus rhamnosus DNA is sufficient for its protective effects, potentially reducing concerns regarding the infectious risk of this novel therapeutic approach.

    Creation of an animal model of necrotizing enterocolitis (NEC) allowing adjustment of severity and potential recoverability is needed to study effectiveness of prevention and treatment strategies. This study describes a novel model in preterm rabbits capable of adjusting severity of NEC-like histologic changes. Rabbit pups (n = 151) were delivered by cesarean section 2 days preterm. In the treatment groups, tissue adhesive was applied to anal openings to simulate the poor intestinal function and dysmotility of preterm neonates. Pups were placed into five groups: 3INT (3 day intermittent block), 4INT (4 day intermittent block), 3COM (3 day complete block), 4COM (4 day complete block), based on differences in type of anal blockage and day of life sacrificed. The fifth group, 4CON, was comprised of a control arm (n = 28) without anal block, with sacrifice of subjects on day 4. All pups were gavage fed with formula contaminated with Enterobacter cloacae, ranitidine, and indomethacin. Following sacrifice, the intestines were harvested for pathologic evidence of NEC. A blinded pathologist graded histologic changes consistent with NEC using a grading scale 0-4 with 4 being most severe. Fifty-seven pups (57/123) (46%) in the research arm survived to sacrifice, compared to 26/28 (93%) in the control arm of the investigation, p < 0.0001. The incidence and severity of NEC-like damage increased with the duration and completeness of the anal blockage. 44/57 (77%) of survivors revealed various degrees of NEC-like damage to large and small bowel, and 3/26 (12%) exhibited early NEC-like mucosal injury in the research and control arms, respectively. This animal model produces NEC-like pathologic changes in both small and large intestine in preterm rabbits. Because incidence and severity of damage increases with duration and completeness of intestinal dysmotility, this allows future effectiveness studies for nonsurgical treatment and prevention of NEC.

    Necrotizing enterocolitis (NEC) is a devastating intestinal disease in preterm infants characterized by barrier disruption, intestinal microbial dysbiosis, and persistent inflammation of the colon, which results in high mortality rates. Current strategies used to manage this disease are not sufficient, although the use of human breast milk reduces the risk of NEC. Mother's milk is regarded as a fundamental nutritional source for neonates, but pasteurization of donor breast milk affects the composition of bioactive compounds. Current research is evaluating the benefits and potential pitfalls of adding probiotics and prebiotics to pasteurized milk so as to improve the functionality of the milk and thereby reduce the burden of illness caused by NEC. Probiotics (live micro-organisms that confer health to the host) and prebiotics (nondigestible oligosaccharides that stimulate the growth of healthy bacteria) are functional foods known to mediate immune responses and modulate microbial populations in the gut. Clinical research shows strain- and compound-specific responses when probiotics or prebiotics are administered in conjunction with donor breast milk for the prevention of NEC. Despite ongoing controversy surrounding optimal treatment strategies, randomized controlled studies are now investigating the use of synbiotics to reduce the incidence and severity of NEC. Synbiotics, a combination of probiotics and prebiotics, have been proposed to enhance beneficial health effects in the intestinal tract more than either agent administered alone. This review considers the implications of using probiotic-, prebiotic-, and synbiotic-supplemented breast milk as a strategy to prevent NEC and issues that could be encountered with the preparations. © 2016 American Society for Nutrition.

    Most cases of necrotizing enterocolitis (NEC) are sporadic, but outbreaks in hospital settings suggest an infectious cause. Our neonatal intensive care unit (NICU) experienced an outbreak of methicillin-sensitive Staphylococcus aureus (MSSA). We aimed to assess whether the enhancement of infection prevention and control measures would be associated with a reduction in the number of cases of NEC. Retrospective chart review. A 24-bed, university-affiliated, inborn level 3 NICU. Infants of less than 30 weeks gestation or birth weight ≤ 1,500 g admitted to the NICU between January 2007 and December 2008 were considered at risk of NEC. All cases of NEC were reviewed. Infection prevention and control measures, including hand hygiene education, were enhanced during the outbreak. Avoidance of overcapacity in the NICU was reinforced, environmental services (ES) measures were enhanced, and ES hours were increased. Two hundred eighty-two at-risk infants were admitted during the study. Their gestational age and birth weight (mean ± SD) were 28.2 ± 2.7 weeks and 1,031 ± 290 g, respectively. The proportion of NEC was 18/110 (16.4%) before the outbreak, 1/54 (1.8%) during the outbreak, and 4/118 (3.4%) after the outbreak. After adjustment for gestational age, birth weight, gender, and singleton versus multiple births, the proportion was lower in the postoutbreak period than in the preoutbreak period (P control measures to manage an MSSA outbreak.

    Synopsis Necrotizing enterocolitis (NEC) is a leading cause of neonatal morbidity and mortality and preventative therapies that are both effective and safe are urgently needed. Current evidence from therapeutic trials suggests that probiotics are effective in decreasing NEC in preterm infants and probiotics are currently the most promising therapy on the horizon for this devastating disease. However, concerns regarding safety and optimal dosing have limited the widespread adoption of routine clinical use of probiotics in preterm infants. In addition, prebiotics and postbiotics may be potential alternatives or adjunctive therapies to the administration of live microorganisms, although studies demonstrating their clinical efficacy in preventing NEC are lacking. This review summarizes the current evidence regarding the use of probiotics, prebiotics and postbiotics in the preterm infant, including its therapeutic role in preventing NEC. PMID:23415261

    Human preterm infants with necrotizing enterocolitis (NEC) have increased circulating and luminal levels of platelet-activating factor (PAF) and decreased serum PAF-acetylhydrolase (PAF-AH), the enzyme that inactivates PAF. Formula supplemented with recombinant PAF-AH decreases NEC in a neonatal rat model. We hypothesized that endogenous PAF-AH contributes to neonatal intestinal homeostasis, and therefore developed PAF-AH−/− mice using standard approaches to study the role of this enzyme in the neonatal NEC model. Following exposure to a well-established NEC model, intestinal tissues were evaluated for histology, pro-inflammatory cytokine mRNA synthesis, and death using standard techniques. We found that mortality rates were significantly lower in PAF-AH−/− pups compared to wild-type controls before 24 hours of life but surviving PAF-AH−/− animals were more susceptible to NEC development compared to wild-type controls. Increased NEC incidence was associated with prominent inflammation characterized by elevated intestinal mRNA expression of sPLA2, iNOS and CXCL1. In conclusion, the data support a protective role for endogenous PAF-AH in the development of NEC, and since preterm neonates have endogenous PAF-AH deficiency, this may place them at increased risk for disease.

    We examined the local hemodynamic response of intestinal loops during acute necrotizing enterocolitis (NEC) in anesthetized rabbits. NEC was induced in ileal loops by transmural injection of a solution containing casein (10 mg/ml) and calcium gluconate (50 mg/ml) acidified to pH 4.0 with propionic or acetic acid. Control loops received casein only (pH 5.0). Mucosal damage was quantified by the blood-to-lumen movement of [51Cr]EDTA, fluid shifts into the lumen, and histology. Mean arterial pressure and loop blood flow were steady over the 3-hr period, loop fluid volume decreased, and there was no evidence of necrosis or epithelial damage. In loops receiving acidified casein and calcium gluconate, there was an immediate dramatic increase in loop blood flow that returned to baseline by 50 min. In addition, loop fluid volume was dramatically increased, necrosis was noted in the form of blunting and loss of villi, and sevenfold increase in [51Cr]EDTA permeability was evident. Administration of CV 1808 (30 mg/kg/hr), a selective adenosine2 agonist, which maintained and elevated loop blood flow throughout the 3 hr protocol, failed to alter the changes in loop fluid volume or prevent necrosis. Histamine levels in loop fluid levels were significantly elevated 20-30 min after NEC induction when compared to saline controls, indicating an early activation of mucosal defenses with this luminal insult. Thus, this model of NEC is characterized by a transient, acute hyperemia, increased intestinal permeability, and histamine release. As mucosal damage was independent of ischemia and could not be prevented by vasodilatory therapy, this model supports the clinical findings that NEC is correlated with luminal factors related to feeding and independent of cardiovascular stress

    Full Text Available Necrotizing enterocolitis is the most frequently occurring gastrointestinal disorder in premature neonates. Animal models of necrotizing enterocolitis and prenatal administration of cortisone have demonstrated that cortisone may accelerate maturation of the mucosal barrier, therefore reducing the incidence of this gastrointestinal disorder. The authors present a review of the literature of the most important risk factors associated with necrotizing enterocolitis, such as inflammatory gastrointestinal mediators, enteral feeding and bacterial colonization, and immaturity of the gastrointestinal barrier, and we emphasize the necessity for additional studies to explore the prenatal administration of cortisone as a preventive strategy for necrotizing enterocolitis.A enterocolite necrosante é a mais freqüente patologia gastrointestinal adquirida no período neonatal, acometendo preferencialmente o recém-nascido prematuro. Estudos experimentais sugerem que a corticoterapia pré-natal acelera a maturação da mucosa gastrintestinal, levando a diminuição da incidência desta doença. Os autores apresentam uma revisão da literatura em relação aos principais fatores fisiopatológicos associados a enterocolite necrosante, tais como mediadores inflamatórios gastrintestinais, nutrição enteral e colonização bacteriana e imaturidade gastrintestinal e enfatizam a necessidade de mais estudos que avaliem a influencia da corticoterapia pré-natal com fator de prevenção da enterocolite necrosante.

    Full Text Available OBJETIVO: Avaliar relatos recentes sobre a enterocolite necrosante, com especial interesse na etiopatogenia, manejo e prevenção. FONTE DOS DADOS: Os artigos utilizados nessa revisão consistem em ensaios randomizados ou semi-randomizados, estudos de caso-controle, metanálises e artigos de revisão recentemente publicados. Alguns outros artigos foram selecionados devido à sua importância para o tema. RESULTADOS: A enterocolite necrosante é uma importante causa de morbimortalidade neonatal em prematuros. Entre esses, os nascidos com retardo de crescimento intra-uterino apresentam um risco mais elevado. O processo fisiopatológico inicia-se intra-útero e continua após o nascimento. Entre outros fatores envolvidos na fisiopatologia, estão a ação da arginina na produção do óxido nítrico intestinal e a ação do fator de crescimento epidérmico na regeneração celular. A perfuração intestinal ainda é um problema cirúrgico, e evidências melhores quanto à sua abordagem precisam ser avaliadas. Após a cirurgia, a extensão da alça intestinal remanescente, a preservação da válvula ileocecal, assim como a utilização precoce de leite materno ou solução de aminoácidos, são determinantes na duração da nutrição parenteral e no sucesso da readaptação intestinal. Estratégias preventivas estão centradas nas práticas alimentares e, recentemente, na suplementação de aminoácidos. CONCLUSÃO: Com um melhor entendimento do processo fisiopatológico, do manejo clínico e cirúrgico, assim como das medidas de prevenção, importantes resultados serão alcançados em termos de redução da morbimortalidade conseqüente à enterocolite necrosante.OBJECTIVE: To evaluate recently reported findings on necrotizing enterocolitis, Paying particular attention to pathogenesis, management and preventative strategies.

    Bacteria are thought to contribute to the pathogenesis of necrotizing enterocolitis (NEC), but it is unknown whether their interaction with the epithelium can participate in the initiation of mucosal injury or they can act only following translocation across a damaged intestinal barrier. Our aims were to determine whether bacteria and intestinal epithelial TLR4 play roles in a well-established neonatal rat model and a novel neonatal murine model of NEC. Neonatal rats, C57BL/6J, C3HeB/FeJ (TLR4 wild type), and C3H/HeJ (TLR4 mutant) mice were delivered by Cesarean section and were subjected to formula feeding and cold asphyxia stress or were delivered naturally and were mother-fed. NEC incidence was evaluated by histological scoring, and gene expression was quantified using quantitative real-time PCR from cDNA generated from intestinal total RNA or from RNA obtained by laser capture microdissection. Spontaneous feeding catheter colonization or supplementation of cultured bacterial isolates to formula increased the incidence of experimental NEC. During the first 72 h of life, i.e., the time frame of NEC development in this model, intestinal TLR4 mRNA gradually decreases in mother-fed but increases in formula feeding and cold asphyxia stress, correlating with induced inducible NO synthase. TLR4, inducible NO synthase, and inflammatory cytokine induction occurred in the intestinal epithelium but not in the submucosa. NEC incidence was diminished in C3H/HeJ mice, compared with C3HeB/FeJ mice. In summary, bacteria and TLR4 play significant roles in experimental NEC, likely via an interaction of intraluminal bacteria and aberrantly overexpressed TLR4 in enterocytes. PMID:16920968

    Full Text Available PURPOSE: To assess the protective effect of glycine in an experimental model of Neonatal Necrotizing Enterocolitis (NEC. METHODS: Fifty (50 neonatal Wistar rats, from a litter of six female rats and weighing 4 to 6 grams, were used. Five animals were cannibalized and the 45 remaining were distributed into three groups: the G1 normal control group (n=12; the G2 Group (n=16, of animals that underwent hypoxia-reoxygenation (HR; the G3 Group of animals (n=17 that underwent HR following a 5% intraperitoneal glycine infusion. The animals underwent hypoxia in a CO2 chamber receiving an air flow of 100% CO2 for 5 minutes and reoxygenation receiving an O2 flow at 100% for 5 minutes. One centimeter long small bowel and colon segments were prepared for histological analysis. The rest of the bowel was removed in a block and frozen at minus 80degreesC for homogenization and determination of tissue malondialdehyde (MDA. Tissue lesions were classified as Grade 0 to Grade 5, according to the level of damaged mucosa. RESULTS: The animals in Group G1 had levels of small bowel and colon lesion significantly smaller as compared to the animals in Groups G2 and G3. The G2 group had mean MDA values significantly higher than the animals in the G1 (p = .015 and G3 (p=0.021 groups. MDA values did not differ significantly (p = 0.992 for the animals in groups G1 and G3. CONCLUSION: Glycine reduces tissue MDA levels (a measurement of lipid peroxidation following HR in neonatal rats.

    Premature infants are highly vulnerable to aberrant gastrointestinal tract colonization, a process that may lead to diseases like necrotizing enterocolitis. Thus, spread of potential pathogens among hospitalized infants is of great concern. Here, we reconstructed hundreds of high-quality genomes of microorganisms that colonized co-hospitalized premature infants, assessed their metabolic potential, and tracked them over time to evaluate bacterial strain dispersal among infants. We compared microbial communities in infants who did and did not develop necrotizing enterocolitis. Surprisingly, while potentially pathogenic bacteria of the same species colonized many infants, our genome-resolved analysis revealed that strains colonizing each baby were typically distinct. In particular, no strain was common to all infants who developed necrotizing enterocolitis. The paucity of shared gut colonizers suggests the existence of significant barriers to the spread of bacteria among infants. Importantly, we demonstrate that strain-resolved comprehensive community analysis can be accomplished on potentially medically relevant time scales.

    Necrotizing enterocolitis (NEC) is a devastating intestinal disease in preterm infants characterized by barrier disruption, intestinal microbial dysbiosis, and persistent inflammation of the colon, which results in high mortality rates. Current strategies used to manage this disease are not sufficient, although the use of human breast milk reduces the risk of NEC. Mother’s milk is regarded as a fundamental nutritional source for neonates, but pasteurization of donor breast milk affects the composition of bioactive compounds. Current research is evaluating the benefits and potential pitfalls of adding probiotics and prebiotics to pasteurized milk so as to improve the functionality of the milk and thereby reduce the burden of illness caused by NEC. Probiotics (live micro-organisms that confer health to the host) and prebiotics (nondigestible oligosaccharides that stimulate the growth of healthy bacteria) are functional foods known to mediate immune responses and modulate microbial populations in the gut. Clinical research shows strain- and compound-specific responses when probiotics or prebiotics are administered in conjunction with donor breast milk for the prevention of NEC. Despite ongoing controversy surrounding optimal treatment strategies, randomized controlled studies are now investigating the use of synbiotics to reduce the incidence and severity of NEC. Synbiotics, a combination of probiotics and prebiotics, have been proposed to enhance beneficial health effects in the intestinal tract more than either agent administered alone. This review considers the implications of using probiotic-, prebiotic-, and synbiotic-supplemented breast milk as a strategy to prevent NEC and issues that could be encountered with the preparations.

    Full Text Available Necrotizing enterocolitis (NEC is a severe disease of the gastrointestinal tract of pre-term babies and is thought to be related to the physiological immaturity of the intestine and altered levels of normal flora in the gut. Understanding the factors that contribute to the pathology of NEC may lead to the development of treatment strategies aimed at re-establishing the integrity of the epithelial wall and preventing the propagation of inflammation in NEC. Several studies have shown a reduced incidence and severity of NEC in neonates treated with probiotics (beneficial bacteria species.The objective of this study is to use a mathematical model to predict the conditions under which probiotics may be successful in promoting the health of infants suffering from NEC. An ordinary differential equation model is developed that tracks the populations of pathogenic and probiotic bacteria in the intestinal lumen and in the blood/tissue region. The permeability of the intestinal epithelial layer is treated as a variable, and the role of the inflammatory response is included. The model predicts that in the presence of probiotics health is restored in many cases that would have been otherwise pathogenic. The timing of probiotic administration is also shown to determine whether or not health is restored. Finally, the model predicts that probiotics may be harmful to the NEC patient under very specific conditions, perhaps explaining the detrimental effects of probiotics observed in some clinical studies.The reduced, experimentally motivated mathematical model that we have developed suggests how a certain general set of characteristics of probiotics can lead to beneficial or detrimental outcomes for infants suffering from NEC, depending on the influences of probiotics on defined features of the inflammatory response.

    Full Text Available Necrotizing enterocolitis (NEC is a common life-threatening condition in premature infants. Bacterial translocation, localized inflammation and subsequent perforation often require surgery for source control and definitive treatment. Small and large intestinal strictures may result from either creation of a surgical anastomosis or the disease process itself. Current methods to treat strictures include, balloon dilation and surgical resection with or without anastomosis. We report the diagnosis and surgical management of a premature infant treated for NEC, who developed an anastomotic stricture and was successfully treated with topical Mitomycin C after balloon stricturoplasty.

    Blackwood, Brian P; Hunter, Catherine J; Grabowski, Julia

    Necrotizing enterocolitis or NEC is the most common gastrointestinal emergency in the newborn. The etiology of NEC remains unknown, and treatment consists of antibiotic therapy and supportive care with the addition of surgical intervention as necessary. Unlike most surgical diseases, clear guidelines for the type and duration of peri-operative antibiotic therapy have not been established. Our aim was to review the antibiotic regimen(s) applied to surgical patients with NEC within a single neonatal intensive care unit (NICU) and to evaluate outcomes and help develop guidelines for antibiotic administration in this patient population. A single-center retrospective review was performed of all patients who underwent surgical intervention for NEC from August 1, 2005 through August 1, 2015. Relevant data were extracted including gestational age, age at diagnosis, gender, pre-operative antibiotic treatment, post-operative antibiotic treatment, development of stricture, and mortality. Patients were excluded if there was incomplete data documentation. A total of 90 patients were identified who met inclusion criteria. There were 56 male patients and 34 female patients. The average gestational age was 30 5/7 wks and average age of diagnosis 16.7 d. A total of 22 different pre-operative antibiotic regimens were identified with an average duration of 10.6 d. The most common pre-operative regimen was ampicillin, gentamicin, and metronidazole for 14 d. A total of 15 different post-operative antibiotic regimens were identified with an average duration of 6.6 d. The most common post-operative regimen was ampicillin, gentamicin, and metronidazole for two days. There were 26 strictures and 15 deaths. No regimen or duration proved superior. We found that there is a high degree of variability in the antibiotic regimen for the treatment of NEC, even within a single NICU, with no regimen appearing superior over another. As data emerge that demonstrate the adverse effects of

    Although partnering with parents is important to improving neonatal outcomes, no studies have investigated what parents are taught, remember, or experience when their child is afflicted with necrotizing enterocolitis (NEC). To characterize parental perceptions of communication and support they were given about NEC. An online survey was developed, reviewed for face validity, and then administered to parents whose child had experienced NEC. Quantitative data were analyzed using descriptive statistics, and qualitative data were analyzed using a qualitative descriptive approach. Parents (N = 110) wanted to know the risk factors and warning signs for NEC and wanted to be told as soon as their child was admitted to the neonatal intensive care unit (NICU). Information provided before diagnosis was felt to be poor by the majority of families, with only 32% feeling satisfied or very satisfied. No parent wrote that they were "scared" by information provided to them about NEC; in fact, parents were dissatisfied when they received "sugar-coated" information. Engaged parents were significantly more satisfied than those who were not informed, had their concerns and suggestions dismissed, or who had to advocate for their baby against clinician opposition (eg, activating the chain of command). Areas for quality improvement include better communication and collaboration with parents through early engagement in NEC prevention using modalities beyond verbal instruction. More research is needed on how best to engage parents, especially to engage in prevention, and how doing so affects satisfaction and outcomes.

    This study assessed whether feeding preterm infants unpasteurized breastmilk (1) decreases the rate of late-onset sepsis and necrotizing enterocolitis and (2) increases the rate of postnatally acquired cytomegalovirus infections. Between January 2008 and July 2013, preterm infants below 32 completed weeks of gestational age admitted to the neonatal intensive care unit of Innsbruck Medical University (Innsbruck, Austria) (n=344) were eligible for the study. Of those, 323 fed breastmilk were retrospectively enrolled in the study. Two groups were formed, with 164 infants being fed unpasteurized and 159 infants being fed pasteurized breastmilk. There was no significant difference in the rate of late-onset sepsis or necrotizing enterocolitis between the unpasteurized and pasteurized breastmilk groups (late-onset sepsis, 15.9% versus 15.1% [p=0.486]; necrotizing enterocolitis, 2.4% versus 4.4% [p=0.254]). The number of infants diagnosed with postnatally acquired cytomegalovirus infection was significantly higher in the unpasteurized group (39.3%) compared with the pasteurized group (4.2%) (p=0.008). Feeding preterm infants unpasteurized breastmilk increases the rate of postnatally acquired cytomegalovirus infections. However, we also demonstrate a nonsignificant trend to a decreased rate of necrotizing enterocolitis in the unpasteurized group, which needs to be confirmed in larger studies.

  14. Impact of antibiotics on necrotizing enterocolitis and antibiotic-associated diarrhea

    Science.gov (United States)

    Silverman, Michael A.; Konnikova, Liza; Gerber, Jeffrey S.

    2017-01-01

    Summary Antibiotics induce changes or dysbiosis of the intestinal microbiome. These antibiotic-induce changes may contribute to the pathogenesis of necrotizing enterocolitis (NEC) and antibiotic-associated diarrhea (AAD). Studies are beginning to unravel the contribution of specific groups of microbes to these diseases—most notably Gammaproteobacteria for NEC and bile acid- and carbohydrate-metabolizing microbes for AAD. Antibiotic-associated diarrhea occurs when antibiotic treatment induces diarrhea by altering the metabolic function of the patient’s intestinal microbiota leading to either an osmotic or infectious diarrhea, most notably Clostridium difficile infection (CDI). Antibiotic therapy impairs the host microbiota’s ability to resist colonization or expansion of pathogenic bacteria. In the case of CDI, there is growing evidence that microbiota-mediated bile acid metabolism is critical in the pathogenesis of this infection. Probiotics or other microbiota-targeted therapies may provide effective strategies to prevent and treat NEC and AAD. PMID:28164853

    The risk factors for necrotizing enterocolitis (NEC) are well known, but the factors involved in the different NEC presentations remain unclear. We hypothesized that digestive dysfunction and intestinal inflammation are mainly affected by severe NEC lesions. In 48 preterm pigs, the association...... between the macroscopic NEC score (range 1-6) and the expression of 48 genes related to inflammation, morphological, and digestive parameters in the distal small intestine was investigated. Only severe NEC cases (score of 5-6) were associated with the upregulation of genes involved in inflammation (CCL2...... and decreased hydrolase activity. A severe inflammatory response and digestive dysfunction are associated mainly with severe NEC. Still, it remains difficult to separate the initial causes of NEC and the later intestinal consequences of NEC in both infants and experimental models....

  16. Platelet-activating factor induces TLR4 expression in intestinal epithelial cells: implication for the pathogenesis of necrotizing enterocolitis.

    Full Text Available Necrotizing enterocolitis (NEC is a leading cause of morbidity and mortality in neonatal intensive care units, however its pathogenesis is not completely understood. We have previously shown that platelet activating factor (PAF, bacteria and TLR4 are all important factors in the development of NEC. Given that Toll-like receptors (TLRs are expressed at low levels in enterocytes of the mature gastrointestinal tract, but were shown to be aberrantly over-expressed in enterocytes in experimental NEC, we examined the regulation of TLR4 expression and signaling by PAF in intestinal epithelial cells using human and mouse in vitro cell lines, and the ex vivo rat intestinal loop model. In intestinal epithelial cell (IEC lines, PAF stimulation yielded upregulation of both TLR4 mRNA and protein expression and led to increased IL-8 secretion following stimulation with LPS (in an otherwise LPS minimally responsive cell line. PAF stimulation resulted in increased human TLR4 promoter activation in a dose dependent manner. Western blotting and immunohistochemical analysis showed PAF induced STAT3 phosphorylation and nuclear translocation in IEC, and PAF-induced TLR4 expression was inhibited by STAT3 and NFκB Inhibitors. Our findings provide evidence for a mechanism by which PAF augments inflammation in the intestinal epithelium through abnormal TLR4 upregulation, thereby contributing to the intestinal injury of NEC.

    Necrotizing enterocolitis (NEC), a gastrointestinal inflammatory disease of unknown etiology that may also affect the liver, causes a great deal of morbidity and mortality in premature infants. We tested the hypothesis that signaling molecules, which are endogenous to the bowel, regulate the severity of intestinal and hepatic damage in an established murine NEC model. Specifically, we postulated that mucosal serotonin (5-HT), which is proinflammatory, would exacerbate experimental NEC and that oxytocin (OT), which is present in enteric neurons and is anti-inflammatory, would oppose it. Genetic deletion of the 5-HT transporter (SERT), which increases and prolongs effects of 5-HT, was found to increase the severity of systemic manifestations, intestinal inflammation, and associated hepatotoxicity of experimental NEC. In contrast, genetic deletion of tryptophan hydroxylase 1 (TPH1), which is responsible for 5-HT biosynthesis in enterochromaffin (EC) cells of the intestinal mucosa, and TPH inhibition with LP-920540 both decrease the severity of experimental NEC in the small intestine and liver. These observations suggest that 5-HT from EC cells helps to drive the inflammatory damage to the gut and liver that occurs in the murine NEC model. Administration of OT decreased, while the OT receptor antagonist atosiban exacerbated, the intestinal inflammation of experimental NEC. Data from the current investigation are consistent with the tested hypotheses-that the enteric signaling molecules, 5-HT (positively) and OT (negatively) regulate severity of inflammation in a mouse model of NEC. Moreover, we suggest that mucosally restricted inhibition of 5-HT biosynthesis and/or administration of OT may be useful in the treatment of NEC. NEW & NOTEWORTHY Serotonin (5-HT) and oxytocin reciprocally regulate the severity of intestinal inflammation and hepatotoxicity in a murine model of necrotizing enterocolitis (NEC).

    Conclusion: Early diagnosis and intensive medical and surgical treatment were mandatory to minimize both morbidity and mortality from NEC. Surgical management should be determined according to the special circumstances of each case. However, the optimum choice between peritoneal drainage and laparotomy remains controversial. Gestational age, birth weight, age at admission, and treatment modality are definite prognostic factors as regard morbidity and mortality of patients with NEC.

    Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of infancy, afflicting 11% of infants born 22–28 weeks gestational age. Both inflammation and oxidation may be involved in NEC pathogenesis through reactive nitrogen species production, protein oxidation and DNA damage. Poly(ADP-ribose) polymerase-1 (PARP-1) is a critical enzyme activated to facilitate DNA repair using nicotinamide adenine dinucleotide (NAD+) as a substrate. However, in the presence of severe oxidative stress and DNA damage, PARP-1 over-activation may ensue, depleting cells of NAD+ and ATP, killing them by metabolic catastrophe. Here we tested the hypothesis that NO dysregulation in intestinal epithelial cells during NEC leads to marked PARP-1 expression and that administration of a PARP-1 inhibitor (nicotinamide) attenuates intestinal injury in a newborn rat model of NEC. In this model, 56% of control pups developed NEC (any stage), versus 14% of pups receiving nicotinamide. Forty-four percent of control pups developed high-grade NEC (grades 3–4), whereas only 7% of pups receiving nicotinamide developed high-grade NEC. Nicotinamide treatment protects pups against intestinal injury incurred in the newborn rat NEC model. We speculate that PARP-1 over-activation in NEC may drive mucosal cell death in this disease and that PARP-1 may be a novel therapeutic target in NEC. PMID:21399558

    Background Plasma nitrite serves as a reservoir of nitric oxide (NO) bioactivity. Because nitrite ingestion is markedly lower in newborns than adults, we hypothesized plasma nitrite levels would be lower in newborns than in adults, and that infants diagnosed with necrotizing enterocolitis (NEC), a disease characterized by ischemia and bacterial invasion of intestinal walls, would have lower levels of circulating nitrite in the days prior to diagnosis. Methods Single blood and urine samples were collected from 9 term infants and 12 adults, 72 preterm infants every 5 d for 3 wk, and from 13 lambs before and after cord occlusion. Results Nitrite fell 50% relative to cord levels in the first day after birth; and within 15 min after cord occlusion in lambs. Urinary nitrite was higher in infants than adults. Plasma and urinary nitrite levels in infants who developed NEC were similar to those of preterm control infants on days 1 and 5, but significantly elevated at 15 and 20 d after birth. Conclusion Plasma nitrite falls dramatically at birth while newborn urinary nitrite levels are significantly greater than adults. Acute NEC is associated with elevated plasma and urinary nitrite levels. PMID:26539663

    Necrotizing enterocolitis (NEC) remains one of the highest causes of mortality and of acute and long-term morbidity in premature infants. Multiple factors are involved in the pathophysiology of NEC including the immaturity of the immune system and the complex changing composition of the intestinal microbiome. This is compounded by the fact that the premature infant should ideally still be a developing fetus and has an immature intestinal tract. Because these complexities are beyond the scope of studies in single-cell cultures, animal models are absolutely essential to understand the mechanisms involved in the pathophysiology of NEC and the effects of inflammation on the immature intestinal tract. To this end, investigators have utilized many different species (e.g., rats, mice, rabbits, quails, piglets, and non-human primates) and conditions to develop models of NEC. Each animal has distinct advantages and drawbacks related to its preterm viability, body size, genetic variability, and cost. The choice of animal model is strongly influenced by the scientific question being addressed. While no model perfectly mimics human NEC, each has greatly improved our understanding of disease. Examples of recent discoveries in NEC pathogenesis and prevention underscore the importance of continued animal research in NEC. Copyright © 2018 Elsevier Inc. All rights reserved.

    The optimal timing of ostomy closure is a matter of debate. We performed a systematic review of outcomes of early ostomy closure (EC, within 8 weeks) and late ostomy closure (LC, after 8 weeks) in infants with necrotizing enterocolitis. PubMed, EMbase, Web-of-Science, and Cinahl were searched for studies that detailed time to ostomy closure, and time to full enteral nutrition (FEN) or complications after ostomy closure. Patients with Hirschsprung's disease or anorectal malformations were excluded. Analysis was performed using SPSS 17 and RevMan 5. Of 778 retrieved articles, 5 met the inclusion criteria. The median score for study quality was 9 [range 8-14 on a scale of 0 to 32 points (Downs and Black, J Epidemiol Community Health 52:377-384, 1998)]. One study described mean time to FEN: 19.1 days after EC (n = 13) versus 7.2 days after LC (n = 24; P = 0.027). Four studies reported complication rates after ostomy closure, complications occurred in 27% of the EC group versus 23% of the LC group. The combined odds ratio (LC vs. EC) was 1.1 [95% CI 0.5, 2.5]. Evidence that supports early or late closure is scarce and the published articles are of poor quality. There is no significant difference between EC versus LC in the complication rate. This systematic review supports neither early nor late ostomy closure.

    To evaluate the efficacy of orally administered Saccharomyces boulardii (S. boulardii) for reducing the incidence and severity of necrotizing enterocolitis (NEC) in very low-birth-weight (VLBW) infants. A prospective, randomised controlled trial was conducted in infants with gestational age ≤32 weeks and birth weight ≤1500 g. The study group received S. boulardii supplementation, and the control group did not. The primary outcomes were death or NEC (Bell's stage ≥2), and secondary outcomes were feeding intolerance and clinical or culture-proven sepsis. A total of 271 infants were enrolled in the study, 135 in the study group and 136 in the control group. There was no significant difference in the incidence of death (3.7% vs. 3.6%, 95% CI of the difference, -5.20-5.25; p = 1.0) or NEC (4.4% vs. 5.1%, 95% CI, -0.65-5.12; p = 1.0) between the groups. However, feeding intolerance and clinical sepsis were significantly lower in the probiotic group compared with control. Although Saccharomyces boulardii supplementation at a dose of 250 mg/day was not effective at reducing the incidence of death or NEC in VLBW infants, it improved feeding tolerance and reduced the risk of clinical sepsis. ©2013 Foundation Acta Paediatrica.

    Full Text Available Necrotizing enterocolitis (NEC is an acute neonatal inflammatory disease that affects the intestine and may result in necrosis, systemic sepsis and multisystem organ failure. NEC affects 5-10% of all infants with birth weight ≤ 1500 g or gestational age less than 30 weeks. Chorioamnionitis (CA is the main manifestation of pathological inflammation in the fetus and is strongly associated with NEC. CA affects 20% of full-term pregnancies and up to 60% of preterm pregnancies and, notably, is often an occult finding. Intrauterine exposure to inflammatory stimuli may switch innate immunity cells such as macrophages to a reactive phenotype (‘priming’. Confronted with renewed inflammatory stimuli during labour or postnatally, such sensitized cells can sustain a chronic or exaggerated production of proinflammatory cytokines associated with NEC (two-hit hypothesis. Via the cholinergic anti-inflammatory pathway, a neurally mediated innate anti-inflammatory mechanism, higher levels of vagal activity are associated with lower systemic levels of proinflammatory cytokines. This effect is mediated by the α7 subunit nicotinic acetylcholine receptor (α7nAChR on macrophages. The gut is the most extensive organ innervated by the vagus nerve; it is also the primary site of innate immunity in the newborn. Here we review the mechanisms of possible neuroimmunological brain-gut interactions involved in the induction and control of antenatal intestinal inflammatory response and priming. We propose a neuroimmunological framework to 1 study the long-term effects of perinatal intestinal response to infection and 2 to uncover new targets for preventive and therapeutic intervention.

    Full Text Available Purpose: To investigate the association between necrotizing enterocolitis (NEC and red blood cell transfusions in very low birth weight (VLBW preterm infants. Methods: We studied were 180 VLBW preterm infants who were admitted to the neonatal intensive care unit of CHA Gangnam Hospital from January of 2006 to December of 2009. The subjects were divided into 2 groups: an NEC group (greater than stage II on the modified Bell’s criteria and a control group (less than stage II on the modified Bell’s critieria. We defined red blood cell transfusion before NEC diagnosis as the frequency of transfusion until NEC diagnosis (mean day at NEC diagnosis, day 18 in the NEC group and the frequency of transfusion until 18 days after birth in the control group. Results: Of the 180 subjects, 18 (10% belonged to the NEC group, and 14 (78% of these 18 patients had a history of transfusion before NEC diagnosis. The NEC group received 3.1±2.9 transfusions, and the control group received 1.0±1.1 transfusions before the NEC diagnosis (P =0.005. In a multivariate logistic regression corrected for gestational age, Apgar score at 1 minute, the presence of respiratory distress syndrome, patent ductus arteriosus, premature rupture of membrane, disseminated intravascular coagulopathy and death were confounding factors. The risk of NEC increased 1.63 times (95% confidence interval, 1.145 to 2.305; P =0.007 with transfusion before the NEC diagnosis. Conclusion: The risk for NEC increased significantly with increased transfusion frequency before the NEC diagnosis.

    Objective: To evaluate the efficacy of orally administered probiotics in preventing necrotizing enterocolitis (NEC) in preterm very low birth weight (VLBW) infants. Study Design: Arandomized double blind controlled trial. Place and Duration of Study: The Paediatrics Department of Sylhet M.A.G. Osmani Medical College Hospital, Sylhet Bangladesh, from July 2012 to June 2015. Methodology: Preterm (28 - 33 weeks gestation) VLBW (birth weight 1000 - 1499 g) neonates were enrolled. The study group was fed with probiotics once daily with breast milk from first feeding, and the control group with only breast milk without the addition of probiotics. Both the groups received other standard care. The primary outcome was the development of NEC (stage II and III), categorized by modified Bell's classification. Result: In 108 neonates, development of NEC was significantly lower in the study group than that of control group [1 (1.9 percent) vs. 6 (11.5 percent); p=0.044]. Age of achievement of full oral feeding was significantly earlier in the study group than that in the control group (14.88 ±3.15 and 18.80 ±4.32 days; p < 0.001). Duration of hospital stay was significantly short in the study group compared to the control group (15.82 ±2.94 days vs. 19.57 ±4.26 days; p < 0.001). Conclusion: Probiotic supplementation reduces the frequency of necrotising enterocolitis in preterm neonates with very low birth weight. It is also associated with faster achievement of full oral feeding and short duration of hospital stay. (author)

    Despite increased efforts, the diverse etiologies of Necrotizing Enterocolitis (NEC) have remained largely elusive. Clinical predictors of NEC remain ill-defined and currently lack sufficient specificity. The development of a thorough understanding of initial gut microbiota colonization pattern in preterm infants might help to improve early detection or prediction of NEC and its associated morbidities. Here we compared the fecal microbiota successions, microbial diversity, abundance and structure of newborns that developed NEC with preterm controls. A 16S rRNA based microbiota analysis was conducted in a total of 132 fecal samples that included the first stool (meconium) up until the 5th week of life or NEC diagnosis from 40 preterm babies (29 controls and 11 NEC cases). A single phylotype matching closest to the Enterobacteriaceae family correlated strongly with NEC. In DNA from the sample with the greatest abundance of this phylotype additional shotgun metagenomic sequencing revealed Citrobacter koseri and Klebsiella pneumoniae as the dominating taxa. These two taxa might represent suitable microbial biomarker targets for early diagnosis of NEC. In NEC cases, we further detected lower microbial diversity and an abnormal succession of the microbial community before NEC diagnosis. Finally, we also detected a disruption in anaerobic microorganisms in the co-occurrence network of meconium samples from NEC cases. Our data suggest that a strong dominance of Citrobacter koseri and/or Klebsiella pneumoniae, low diversity, low abundance of Lactobacillus, as well as an altered microbial-network structure during the first days of life, correlate with NEC risk in preterm infants. Confirmation of these findings in other hospitals might facilitate the development of a microbiota based screening approach for early detection of NEC. PMID:29187842

    Necrotizing enterocolitis (NEC) is a costly gastrointestinal disorder that mainly affects preterm and low-birth-weight infants and can lead to considerable morbidity and mortality. Mother's own milk is protective against NEC but is not always available. In such cases, donor human milk has also been shown to be protective (although to a lesser extent) compared with formula milk, but it is more expensive. This systematic review aimed at evaluating the cost of donor milk, the cost of treating NEC, and the cost-effectiveness of exclusive donor milk versus formula milk feeding to reduce the short-term health and treatment costs of NEC. We systematically searched five relevant databases to find studies with verifiable costs or charges of donor milk and/or treatment of NEC and any economic evaluations comparing exclusive donor milk with exclusive formula milk feeding. All search results were double screened. Seven studies with verifiable donor milk costs and 17 with verifiable NEC treatment costs were included. The types of cost or charge included varied considerably across studies, so quantitative synthesis was not attempted. Estimates of the incremental length of stay associated with NEC were ∼18 days for medical NEC and 50 days for surgical NEC. Two studies claimed to report economic evaluations but did not do so in practice. It is likely that donor milk provides short-term cost savings by reducing the incidence of NEC. Future studies should provide more details on cost components included and a full economic evaluation, including long-term outcomes, should be undertaken.

    Necrotizing enterocolitis (NEC) remains one of the most common underlying diagnoses of short bowel syndrome (SBS) in children. The relationship between the etiology of SBS and ultimate enteral autonomy has not been well studied. This investigation sought to evaluate the rate of achievement of enteral autonomy in SBS patients with and without NEC. Following IRB approval, 109 patients (2002-2014) at a multidisciplinary intestinal rehabilitation program were reviewed. The primary outcome evaluated was achievement of enteral autonomy (i.e. fully weaning from parenteral nutrition). Patient demographics, primary diagnosis, residual small bowel length, percent expected small bowel length, median serum citrulline level, number of abdominal operations, status of the ileocecal valve (ICV), presence of ileostomy, liver function tests, and treatment for bacterial overgrowth were recorded for each patient. Median age at PN onset was 0 weeks [IQR 0-0]. Median residual small bowel length was 33.5 cm [IQR 20-70]. NEC was present in 37 of 109 (33.9%) of patients. 45 patients (41%) achieved enteral autonomy after a median PN duration of 15.3 [IQR 7.2-38.4]months. Overall, 64.9% of patients with NEC achieved enteral autonomy compared to 29.2% of patients with a different primary diagnosis (p=0.001, Fig. 1). Patients with NEC remained more likely than those without NEC to achieve enteral autonomy after two (45.5% vs. 12.0%) and four (35.7% vs. 6.3%) years on PN (Fig. 1). Logistic regression analysis demonstrated the following parameters as independent predictors of enteral autonomy: diagnosis of NEC (pChildren with SBS because of NEC have a significantly higher likelihood of fully weaning from parenteral nutrition compared to children with other causes of SBS. Additionally, patients with NEC may attain enteral autonomy even after long durations of parenteral support. Copyright © 2016 Elsevier Inc. All rights reserved.

    Erica M Carlisle

    Full Text Available INTRODUCTION: Necrotizing enterocolitis (NEC affects 5-10% of infants born weighing less than 1500 g. Most models of NEC recapitulate late-stage disease with gut necrosis and elevated inflammatory mediators. Evaluation of NEC at earlier, less lethal stages of disease will allow investigation of initial disease triggers and may advance our understanding of temporal relationships between factors implicated in NEC pathogenesis. In this manuscript, we describe our investigation of early NEC and test the hypothesis that bacteria and inflammatory mediators differ between animals with early NEC and disease free animals. METHODS: On DOL7 C3HeB/FeJ pups were fed liquid formula with 1×10(4 Streptococcus thoraltensis, Serratia marcescens, and Pseudomonas aeruginosa every 3 h. To initiate NEC, pups underwent asphyxia (100% N(2 for 90 s and hypothermia (4°C for 10 min after feeding. Pups were euthanized at 72 h. Intestines were collected for histologic NEC scoring and DNA/RNA extraction. Bacterial populations were identified by 16S rRNA pyrosequencing and principal component analysis (PCA. RNA isolates underwent QRT-PCR for Toll-like Receptor 4 (TLR4 and inducible nitric oxide synthase (iNOS. RESULTS: Despite histologic, intestinal damage in mice with NEC, no gross necrosis was observed suggesting early disease. QRT-PCR yielded no difference between groups in TLR4 or iNOS mRNA levels. PCA demonstrated relative clustering of microbial communities based on presence or absence of NEC. 16S pyrosequencing demonstrated similar phyla between groups (Firmicutes and Proteobacteria predominated in all animals. However, the colonic microbiota of animals with NEC had more Citrobacter (p<0.01, Klebsiella (p<0.05, and Tatumella (p<0.05, while that of animals without NEC had more Streptococcus (p<0.01 and Enterococcus (p<0.01.

    Background: A rapid advance in enteral feeding is associated with necrotizing enterocolitis (NEC) in preterm infants. Therefore, minimal enteral nutrition (MEN) combined with parenteral nutrition (PN) is common clinical practice, but the effects on NEC and intestinal function remain poorly...... characterized. It was hypothesized that a commonly used MEN feeding volume (16-24 mL/kg/d) prevents NEC and improves intestinal structure, function, and microbiology in preterm pigs. Methods: After preterm birth pigs were stratified into 4 nutrition intervention groups that received the following treatments: (1...... later formula-induced gut dysfunction and NEC. However, in CF pigs, intestinal lesions were restricted to the colon, compared with all regions in OF and FF pigs, which indicated proximal protection of colostrum MEN. Bacterial composition was not affected by MEN, diet, or NEC outcomes, but bacterial load...

  17. The effect of bovine colostrum products on intestinal dysfunction and inflammation in a preterm pig model of necrotizing enterocolitis

    Støy, Ann Cathrine Findal

    Necrotizing enterocolitis (NEC), primarily seen in preterm infants, is associated with high morbidity and mortality. The pathogenesis is not fully understood but risk factors include prematurity, enteral feeding (especially with milk formula), and the intestinal microbiota. Mother’s milk, rich...... in bioactive factors, has a protective effect against NEC, but not all preterm infants are able to receive mother’s milk. The overall aim of this thesis was to investigate if bovine colostrum (BC), also rich in bioactive factors, could serve as an alternative to mother’s milk. A preterm pig model of NEC...... formula. All three BC products maintained trophic and anti-inflammatory effects on the immature pig intestine.

    Probiotics have strain specific effects and the effects of fungi in preventing diseases in preterm infants have been investigated poorly. Saccharomyces boulardii is a yeast which acts both as a probiotic and a polyamine producer. The objective of this study was to investigate the efficacy of S. boulardii in preventing necrotizing enterocolitis (NEC) or sepsis in very low birth weight infants. A prospective, double blind, placebo controlled trial was conducted in preterm infants (≤ 32 GWs, ≤ 1500 g birth weight). They were randomized either to receive feeding supplementation with S. boulardii 50 mg/kg every 12 h or placebo, starting with the first feed until discharged. Necrotizing enterocolitis (NEC) or sepsis and NEC or death. Birth weight and gestational age of the study (n = 104) and the control (n = 104) groups were 1126 ± 232 vs 1162 ± 216 g and 28.8 ± 2.2 vs 28.7 ± 2.1 weeks, respectively. Neither the incidence of stage ≥ 2 NEC or death nor stage ≥ 2 NEC or late onset culture proven sepsis was significantly lower in the study group when compared with the control group (9.6% vs 7.7%, p = 0.62; 28.8% vs 23%, p = 0.34). Time to reach 100 mL/kg/day of enteral feeding (11.9 ± 7 vs 12.6 ± 7 days, p = 0.37) was not different between the groups. Saccharomyces boulardii did not decrease the incidence of NEC or sepsis. © 2013 Elsevier Ireland Ltd. All rights reserved.

    It has been suggested that probiotics can reduce the overgrowth of pathogens in the bowels of preterm infants and contribute to the reduction of the incidence of nosocomial infections in neonatal intensive care units (NICUs). The purpose of this study was to evaluate the effectiveness of Lactobacillus GG supplementation in reducing the incidence of urinary tract infections (UTIs), bacterial sepsis and necrotizing enterocolitis (NEC) in preterm infants. A double-blind study was conducted in 12 Italian NICUs. Newborn infants with a gestational age probiotics group (n = 295) and the placebo group (n = 290) exhibited similar clinical characteristics. The duration of Lactobacillus GG and placebo supplementation was 47.3 +/- 26.0 and 48.2 +/- 24.3 days, respectively. Although UTIs (3.4 vs. 5.8%) and NEC (1.4 vs. 2.7%) were found less frequently in the probiotic group compared to the control group, these differences were not significant. Bacterial sepsis was more frequent in the probiotics group (4.4%, n = 11) than in the placebo group (3.8%, n = 9), but the difference was not significant. Seven days of Lactobacillus GG supplementation starting with the first feed is not effective in reducing the incidence of UTIs, NEC and sepsis in preterm infants. Further studies are required to confirm our results in lower birthweight populations. Copyright 2002 S. Karger AG, Basel

    Abstract Introduction Necrotizing fasciitis in neonates is rare and is associated with almost 50% mortality. Although more than 80 cases of neonates (under one month of age) with necrotizing fasciitis have been reported in the literature, only six of them are identified as originating in the scrotum. Case presentation We report the case of a four-week-old, full-term, otherwise-healthy Caucasian baby boy who presented with an ulcerating lesion of his scrotal wall. His scrotum was explored because of a provisional diagnosis of missed torsion of the testis. He was found to have necrotizing fasciitis of the scrotum. We were able to preserve the testis and excise the necrotic tissue, and with intravenous antibiotics there was a successful outcome. Conclusions Fournier gangrene is rarely considered as part of the differential diagnosis in the clinical management of the acute scrotum. However, all doctors who care for small babies must be aware of this serious condition and, if it is suspected, should not hesitate in referring the babies to a specialist pediatric surgical center immediately.

    Preterm infants are extremely vulnerable to a range of morbidities and mortality. Underdeveloped cardiac, respiratory, gastrointestinal, and immune systems in the preterm period increase the risk of necrotizing enterocolitis (NEC), a serious disease of the gut. NEC affects 5–12% of very–low birth-weight infants, leads to surgery in 20–40% of cases, and is fatal in 25–50% of cases. There are multiple factors that may contribute to NEC, but the exact cause is not yet fully understood. Severe cases can result in intestinal resection or death, and the health care costs average >$300,000/infant when surgical management is required. Different types of nutrition may affect the onset or progression of NEC. Several studies have indicated that bovine milk–based infant formulas lead to a higher incidence of NEC in preterm infants than does human milk (HM). However, it is not clear why HM is linked to a lower incidence of NEC or why some infants fed an exclusively HM diet still develop NEC. An area that has not been thoroughly explored is the use of semielemental or elemental formulas. These specialty formulas are easy to digest and absorb in the gut and may be an effective nutritional intervention for reducing the risk of NEC. This review summarizes what is known about the factors that contribute to the onset and progression of NEC, discusses its health care cost implications, and explores the impact that different formulas and HM have on this disease.

    Full Text Available Necrotizing enterocolitis (NEC is a critical intestinal emergency condition, which mainly occurs in preterm very low birth weight (PVLBW infants. Despite remarkable advances in the care of PVLBW infants, with considerable improvement of the survival rate in recent decades, the incidence of NEC and NEC-related mortality have not declined accordingly. The fast progression from nonspecific signs to extensive necrosis also makes primary prevention the first priority. Recently, increasing evidence has indicated the important role of several nutrients in primary prevention of NEC. Therefore, the aim of this review is to summarize some potential immunomodulatory nutrients in the prevention of NEC, including bovine colostrum, probiotics, prebiotics (e.g., human milk oligosaccharides, long chain polyunsaturated fatty acids, and amino acids (glutamine, cysteine and N-acetylcysteine, l-arginine and l-citrulline. Based on current research evidence, probiotics are the most documented effective method to prevent NEC, while others still require further investigation in animal studies and clinical randomized controlled trials.

    Full Text Available Necrotizing fasciitis (NF is a rapidly progressive and potentially life-threatening infection of superficial fascia and subcutaneous tissue. Thoracic wall is one of the rarest locations for NF. Broadspectrum antibiotics receiving, early surgical debridement, and skin grafting are life saving in NF. We report a 7-day-old female neonate who had left sided thoracic wall NF. She had undergone extensive surgical debridement within 4 hours of hospital admission, and reconstruction of skin defect by split-thickness skin grafting later. Early diagnosis is important, as prompt surgical debridement offers the best chance for survival. Early and extensive surgical debridement is a widely accepted clinical approach and the mainstay of effective treatment. The goals of surgical intervention are to remove all necrotic tissues, and to help control the progression of NF. Reconstruction of skin defects should be performed by early split-thickness skin grafting like our patient or primary closure. Because early wound resurfacing prevents fluid, electrolyte, and protein loss from the wound site, and decreases secondary infection. Although chest wall NF is rare in neonates, it is a rapidly spreading, highly lethal infection. A high index of suspicion, early diagnosis, and aggressive approach are essential to its successful treatment.

    Full Text Available Some oral probiotics have been shown to prevent necrotizing enterocolitis (NEC and decrease mortality effectively in preterm very low birth weight (PVLBW infants. However, it is unclear whether a single probiotic or a mixture of probiotics is most effective for the prevention of NEC.A meta-analysis was conducted by reviewing the most up to date literature to investigate whether multiple strains probiotics are more effective than a single strain in reducing NEC and death in PVLBW infants.Relevant studies were identified by searches of the MEDLINE, EMBASE, and Cochrane CENTRAL databases, from 2001 to 2016.The inclusion criteria were randomized controlled trials of any enteral probiotic supplementation that was initiated within the first 7 days and continued for at least 14 days in preterm infants (≤ 34 weeks' gestation and/or those of a birth weight ≤1500 g.A total of 25 trials (n = 7345 infants were eligible for inclusion in the meta-analysis using a fixed-effects model. Multiple strains probiotics were associated with a marked reduction in the incidence of NEC, with a pooled OR of 0.36 (95% CI, 0.24-0.53; P < .00001. Single strain probiotic using Lactobacillus species had a borderline effect in reducing NEC (OR of 0.60; 95% CI 0.36-1.0; P = .05, but not mortality. Multiple strains probiotics had a greater effectiveness in reducing mortality and were associated with a pooled OR of 0.58 (95% CI, 0.43-0.79; P = .0006. Trials using single strain of Bifidobacterium species and Saccharomyces boulardii did not reveal any beneficial effects in terms of reducing NEC or mortality.This updated report found that multiple strains probiotics appear to be the most feasible and effective strategy for the prevention of NEC and reduction of mortality in PVLBW neonates. Further clinical trials should focus on which probiotic combinations are most effective.

    Full Text Available Necrotizing enterocolitis (NEC is an inflammatory disease of the intestine in premature infants. Lactobacillus reuteri DSM 17938 improves survival and reduces the incidence and severity of NEC in a rodent model. Foxp3(+ regulatory T cells (Tregs maintain intestinal homeostasis by controlling inflammation and inducing tolerance. To determine whether there are insufficient numbers of Tregs to control inflammation in NEC and to determine if LR17938 increases the frequency of Tregs, we studied selected groups of newborn Sprague-Dawley rats according to feeding plan: dam±LR17938, formula±LR17938, and NEC±LR17938. NEC was induced by gavage feeding with special formula and exposure to hypoxic conditions. Lymphocytes isolated from ileum, mesenteric lymph nodes (MLN, spleen and thymus were labeled for T cell surface markers (CD3, CD4, CD8 and intracellular Foxp3; and labeled cells were analyzed by flow cytometry. The percentage of CD3(+ T cells and Foxp3(+ Tregs in the ileum significantly decreased in pups with NEC, compared to normal controls. Feeding LR17938 to neonatal rats with NEC increased the % of Foxp3(+ T cells in the ileum while decreasing the percentage of cells in the MLN. Administration of LR17938 to dam-fed rats significantly increased Foxp3(+Tregs in the ileum as early as day of life (DOL1 but did not produce an increase in Tregs in formula-fed rats on DOL1. These results suggest that factors in breast milk may enhance the early immunomodulatory effects of LR17938. An anti-inflammatory effect of LR17938 in NEC was associated with the modulation of immune responses and induction and what appears to be migration of Foxp3(+ Tregs to the diseased gut. Probiotic-facilitated development of Tregs might play an important role in the prevention of NEC.

    To evaluate if there are differences regarding disease location and mortality of necrotizing enterocolitis, according to the gestational age at birth, in newborns submitted to surgery due to enterocolite. A historical cohort study of 198 newborns submitted to surgery due to necrotizing enterecolitis in a tertiary hospital, from November 1991 to December 2012. The newborns were divided into different categories according to gestational age (<30 weeks, 30-33 weeks and 6 days, 34-36 weeks and 6 days, and ≥37 weeks), and were followed for 60 days after surgery. The inclusion criterion was the presence of histological findings of necrotizing enterocolitis in the pathology. Patients with single intestinal perforation were excluded. The jejunum was the most commonly affected site in extremely premature infants (p=0.01), whereas the ileum was the most commonly affected site in premature infants (p=0.002), and the colon in infants born at term (p<0.001). With the increasing gestational age, it was observed that intestinal involvement decreased for the ileum and the jejunum (decreasing from 45% to 0% and from 5% to 0%, respectively), with a progressive increase in colon involvement (0% to 84%). Total mortality rate was 45.5%, and no statistical difference was observed in the mortality at different gestational ages (p=0.287). In newborns submitted to surgery due to necrotizing enterocolitis, the disease in extremely preterm infants was more common in the jejunum, whereas in preterm infants, the most affected site was the ileum, and in newborns born close to term, it was the colon. No difference in mortality was observed according to the gestational age at birth. Copyright © 2017 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

    Necrotizing enterocolitis (NEC) is a complex disease involving prematurity, enteral feeding, and bacterial effects. We propose that the underlying initial condition in its pathogenesis is reduced ability of the neonatal gut epithelial cells (NGECs) to clear oxidative stress (OS), and that when such a NGEC population is exposed to enteral feeding, the increased metabolic OS tips the population toward apoptosis, inflammation, bacterial activation, and eventual necrosis. The multi-factorial complexity of NEC requires characterization with computational modeling, and herein, we used an agent-based model (ABM) to instantiate and examine our unifying hypothesis of the pathogenesis of NEC. An ABM of the neonatal gut was created with NGEC computational agents incorporating rules for pathways for OS, p53, tight junctions, Toll-like receptor (TLR)-4, nitric oxide, and nuclear factor-kappa beta (NF-κB). The modeled bacteria activated TLR-4 on contact with NGECs. Simulations included parameter sweeps of OS response, response to feeding, addition of bacteria, and alterations in gut mucus production. The ABM reproduced baseline cellular respiration and clearance of OS. Reduction in OS clearance consistent with clinical NEC led to senescence, apoptosis, or inflammation, with disruption of tight junctions, but rarely to NGEC necrosis. An additional "hit" of bacteria activating TLR-4 potentiated a shift to NGEC necrosis across the entire population. The mucus layer was modeled to limit bacterial-NGEC interactions and reduce this effect, but concomitant apoptosis in the goblet cell population reduced the efficacy of the mucus layer and limited its protective effect in simulated experiments. This finding suggests a means by which increased apoptosis at the cellular population level can lead to a transition to the necrosis outcome. Our ABM incorporates known components of NEC and demonstrates that impaired OS management can lead to apoptosis and inflammation of NGECs, rendering the

    Background: The pathophysiology of necrotizing enterocolitis (NEC) remains poorly understood. Objective: We assessed the relation between feeding strategies, intestinal microbiota composition, and the development of NEC. Design: We performed a prospective nationwide population-based study, EPIPAGE 2 (Etude Epidémiologique sur les Petits Ages Gestationnels), including preterm infants born at Etude Epidémiologique de la flore), in 20 of the 64 NICUs, analyzed the intestinal microbiota by culture and 16S ribosomal RNA gene sequencing. Results: Among the 3161 enrolled preterm infants, 106 (3.4%; 95% CI: 2.8%, 4.0%) developed NEC. Individual characteristics were significantly associated with NEC. Slower and intermediate rates of progression of enteral feeding strategies were associated with a higher risk of NEC, with an adjusted OR of 2.3 (95% CI: 1.2, 4.5; P = 0.01) and 2.0 (95% CI: 1.1, 3.5; P = 0.02), respectively. Less favorable and intermediate direct-breastfeeding policies were associated with higher NEC risk as well, with an adjusted OR of 2.5 (95% CI: 1.1, 5.8; P = 0.03) and 2.3 (95% CI: 1.1, 4.8; P = 0.02), respectively. Microbiota analysis performed in 16 cases and 78 controls showed an association between Clostridium neonatale and Staphylococcus aureus with NEC ( P = 0.001 and P = 0.002). Conclusions: A slow rate of progression of enteral feeding and a less favorable direct-breastfeeding policy are associated with an increased risk of developing NEC. For a given level of risk assessed by propensity score, colonization by C. neonatale and/or S. aureus is significantly associated with NEC.

    Full Text Available Enteral formula feeding is a risk factor for necrotizing enterocolitis (NEC in premature infants, yet studies are conflicting regarding the safest timing for introduction and advancement of feeds. Our aim was to test the effects of early vs. late initiation and abrupt vs. gradual advancement of enteral feeding of an intact vs. hydrolyzed protein formula on NEC incidence and severity in preterm pigs. In Experiment 1, preterm pigs received total parenteral nutrition (TPN at birth with abrupt initiation of enteral formula feeds (50% full intake on d of life (DOL 2 (EA or 5 (LA while PN continued. Pigs were also fed formula containing either intact or hydrolyzed protein. In Experiment 2, preterm pigs received TPN at birth with enteral, hydrolyzed-protein formula feeds introduced on DOL 2 either abruptly (EA; 50% full feeds or gradually (EG; 10-50% full feeds over 5 d while PN continued. NEC incidence and severity were assessed based on macroscopic and histological scoring. In Experiment 1, NEC incidence (41% vs. 70%, P<0.05 and severity were reduced in LA vs. EA groups and LA was associated with a higher survival rate, daily weight gain and jejunum villus height. Piglets fed hydrolyzed vs. intact protein formula had lower stomach content weights and similar NEC incidence. In Experiment 2, NEC incidence and severity were not different between pigs the EG vs. EA group. Proinflammatory gene expression (IL-1β, IL-6 and S100A9 in the ileum was lower in both LA and EG vs. EA groups. In conclusion, delayed initiation but not gradual advancement of enteral feeding is protective against NEC in preterm pigs. Feeding hydrolyzed vs. intact protein formula improved gastric transit without affecting the NEC incidence.

    Necrotizing enterocolitis (NEC) is the leading gastrointestinal cause of mortality and morbidity in the premature infant. Premature infants have a delay in intestinal colonization by commensal bacteria and colonization with potentially pathogenic organisms. Lactobacillus reuteri is a probiotic that inhibits enteric infections, modulates the immune system, and may be beneficial to prevent NEC. In previous studies, L. reuteri strains DSM 17938 and ATCC PTA 4659 differentially modulated inflammation in vitro; however, the strains had equivalent anti-inflammatory responses in LPS feeding-induced ileitis in neonatal rats in vivo. The impact of these two strains in the prevention of NEC has not been previously investigated. NEC was induced in newborn rats by orogastric formula feeding and exposure to hypoxia. L. reuteri was added to the formula to prevent NEC. NEC score, Toll-like receptor (TLR)-signaling genes, phospho-IκB activity, and cytokine levels in the intestine were examined. Both strains significantly increased survival rate and decreased the incidence and severity of NEC, with optimal effects from DSM 17938. In response to probiotic, mRNA expression of IL-6, TNF-α, TLR4, and NF-κB was significantly downregulated, while mRNA levels of anti-inflammatory cytokine IL-10 were significantly upregulated. In parallel, L. reuteri treatment led to decrease intestinal protein levels of TLR4 and cytokine levels of TNF-α and IL-1β in newborn rats with NEC. Both strains significantly inhibited not only intestinal LPS-induced phospho-IκB activity in an ex vivo study but also decreased the levels of phospho-IκB in the intestines of NEC rat model. Cow milk formula feeding produced a similar but milder proinflammatory profile in the intestine that was also ameliorated by 17938. Our studies demonstrate that each of the two L. reuteri strains has potential therapeutic value in our NEC model and in enteritis associated with cow milk feeding. These results support the

    Within the ORACLE Children Study Cohort, the authors have evaluated long-term consequences of the diagnosis of confirmed or suspected neonatal necrotising enterocolitis (NEC) at age of 7 years. Outcomes were assessed using a parental questionnaire, including the Health Utilities Index (HUI-3) to assess functional impairment, and specific medical and behavioural outcomes. Educational outcomes for children in England were explored using national standardised tests. Multiple logistic regression was used to explore independent associates of NEC within the cohort. The authors obtained data for 119 (77%) of 157 children following proven or suspected NEC and compared their outcomes with those of the remaining 6496 children. NEC was associated with an increase in risk of neonatal death (OR 14.6 (95% CI 10.4 to 20.6)). At 7 years, NEC conferred an increased risk of all grades of impairment. Adjusting for confounders, risks persisted for any HUI-3 defined functional impairment (adjusted OR 1.55 (1.05, 2.29)), particularly mild impairment (adjusted OR 1.61 (1.03, 2.53)) both in all NEC children and in those with proven NEC, which appeared to be independent. No behavioural or educational associations were confirmed. Following NEC, children were more likely to suffer bowel problems than non-NEC children (adjusted OR 3.96 (2.06, 7.61)). The ORACLE Children Study provided opportunity for the largest evaluation of school age outcome following neonatal NEC and demonstrates significant long-term consequences of both gut function (presence of stoma, admission for bowel problems and continuing medical care for gut-related problems) and motor, sensory and cognitive outcomes as measured using HUI-3.

    To conduct a systematic review of neonatal necrotising enterocolitis (NEC) rates in high-income countries published in peer-reviewed journals. We searched MEDLINE, Embase and PubMed databases for observational studies published in peer-reviewed journals. We selected studies reporting national, regional or multicentre rates of NEC in 34 Organisation for Economic Co-operation and Development countries. Two investigators independently screened studies against predetermined criteria. For included studies, we extracted country, year of publication in peer-reviewed journal, study time period, study population inclusion and exclusion criteria, case definition, gestation or birth weight-specific NEC and mortality rates. Of the 1888 references identified, 120 full manuscripts were reviewed, 33 studies met inclusion criteria, 14 studies with the most recent data from 12 countries were included in the final analysis. We identified an almost fourfold difference, from 2% to 7%, in the rate of NEC among babies born REVIEWS REGISTRATION NUMBER: CRD42015030046. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The assembly and development of the gut microbiome in infants have important consequences for immediate and long-term health. Preterm infants represent an abnormal case for bacterial colonization because of early exposure to bacteria and frequent use of antibiotics. To better understand the assembly of the gut microbiota in preterm infants, fecal samples were collected from 32 very low birth weight preterm infants over the first 6 weeks of life. Infant health outcomes included health, late-onset sepsis, and necrotizing enterocolitis (NEC). We characterized bacterial compositions by 16S rRNA gene sequencing and metabolomes by untargeted gas chromatography-mass spectrometry. Preterm infant fecal samples lacked beneficial Bifidobacterium spp. and were dominated by Enterobacteriaceae , Enterococcus , and Staphylococcus organisms due to nearly uniform antibiotic administration. Most of the variance between the microbial community compositions could be attributed to the baby from which the sample derived (permutational multivariate analysis of variance [PERMANOVA] R 2 = 0.48, P PERMANOVA R 2 = 0.43, P < 0.001) and weakly associated with bacterial composition (Mantel statistic r = 0.23 ± 0.05, P < 0.05). No measured metabolites were found to be associated with necrotizing enterocolitis, late-onset sepsis, or a healthy outcome. Overall, preterm infant gut microbial communities were personalized and reflected antibiotic usage. IMPORTANCE Preterm infants face health problems likely related to microbial exposures, including sepsis and necrotizing enterocolitis. However, the role of the gut microbiome in preterm infant health is poorly understood. Microbial colonization differs from that of healthy term babies because it occurs in the NICU and is often perturbed by antibiotics. We measured bacterial compositions and metabolomic profiles of 77 fecal samples from 32 preterm infants to investigate the differences between microbiomes in health and disease. Rather than finding

    Full Text Available The Necrotizing enterocolitis (NEC is a serious illness of the newborn that affects mainly the preterm infant. It corresponds to a diffuse intestinal necrosis with more affection of the ileocecal region. The pathophysiology is complex and multiple risk factors can cause the illness in a susceptible infant. Among the different theories about their appearance is observed that prematurity, intestinal isquemia, bacterial colonization and enteral feeding are the main risk factors, which can be favored by prenatal, perinatal or postnatal conditions. The aim of this article is to review the pathophysiology and the risk factors described in the current evidence. La enterocolitis necrosante (ECN es una grave enfermedad propia del recién nacido (RN que afecta principalmente a los RN pretérmino (RNPT. Corresponde a una necrosis isquémica de la mucosa intestinal con mayor afección de la región ileocecal. La fisiopatología es compleja y en ella participan múltiples factores de riesgo que pueden ocasionar la enfermedad en un RN susceptible. Entre las diferentes teorías acerca de su aparición se observa reiteradamente que la prematuridad, la isquemia intestinal, la colonización bacteriana y la alimentación enteral se repiten como los factores de riesgo principales, los cuales pueden ser favorecidos por condiciones prenatales, perinatales o posnatales. Se revisan la fisiopatología y los factores de riesgo implicados en la génesis de esta enfermedad.

    Full Text Available The aim of this study was to describe the epidemiology of necrotising enterocolitis (NEC, antibiotic consumption and the usefulness of microbiological tests in very low birth weight (VLBW Polish newborns.Prospective surveillance was performed in the year 2009 by local infection control teams. The study covered 910 infants hospitalized in six Polish neonatal intensive care units. Two kinds of indicators were used for the description of antibiotic usage: the duration of treatment (days of treatment, DOTs and the defined daily dose (DDD.NEC incidence was 8.7% and fatality rate was 19%. Chorioamnionitis, late gestational age and low birth weight were identified as risk factors for NEC. Catheterization, mechanical ventilation and other selected procedures were used considerably longer in newborns with NEC than in the remaining neonates. Total usage of antibiotics reached 2.9 DDDs or 1.437 days; the average use of drugs per case of NEC amounted to 0.47 DDD or 23.2 DOTs. The level of antibiotic usage was analysed with correlation to microbiological tests performed and it was non-significantly greater in the group of children with NEC in whom the tests were performed.A high risk of developing NEC is closely associated with VLBW and with inflammation of the amnion during labour. We observed no relationship between the consumption of antibiotics in neonates with NEC and positive results of microbiological testing indicating sepsis accompanying NEC or gut colonization with pathogens.

    Probiotics are increasingly used as a supplement to prevent adverse health outcomes in preterm infants. We conducted a systematic review, meta-analysis, and subgroup analysis of findings from randomized controlled trials (RCTs) to assess the magnitude of the effect of the probiotics on health outcomes among very-low-birth-weight (VLBW) infants. Relevant articles from January 2003 to June 2017 were selected from a broad range of databases, including Medline, PubMed, Scopus, and Embase. Studies were included if they used an RCT design, involved a VLBW infant (birthweight probiotic intervention group, measured necrotizing enterocolitis (NEC) as a primary outcome, and measured sepsis, mortality, length of hospital stay, weight gain, and intraventricular hemorrhage (IVH) as additional outcomes. The initial database search yielded 132 potentially relevant articles and 32 ( n = 8998 infants) RCTs were included in the final meta-analysis. Subgroup analysis was used to evaluate the effects of the moderators on the outcome variables. In the probiotics group, it was found that NEC was reduced by 37% (95% CI: 0.51%, 0.78%), sepsis by 37% (95% CI: 0.72%, 0.97%), mortality by 20% (95% CI: 0.67%, 0.95%), and length of hospital stay by 3.77 d (95% CI: -5.94, -1.60 d). These findings were all significant when compared with the control group. There was inconsistent use of strain types among some of the studies. The results indicate that probiotic consumption can significantly reduce the risk of developing medical complications associated with NEC and sepsis, reduce mortality and length of hospital stay, and promote weight gain in VLBW infants. Probiotics are more effective when taken in breast milk and formula form, consumed for Probiotics are not effective in reducing the incidence of IVH in VLBW infants. © 2017 American Society for Nutrition.

    Full Text Available Background: Oxidative stress and inflammation may contribute to the disruption of the protective gut barrier through various mechanisms; mitochondrial dysfunction resulting from inflammatory and oxidative injury may potentially be a significant source of apoptosis during necrotizing enterocolitis (NEC. Tumor necrosis factor (TNFα is thought to generate reactive oxygen species (ROS and activate the apoptosis signal-regulating kinase 1 (ASK1-c-Jun N-terminal kinase (JNK/p38 pathway. Hence, the focus of our study was to examine the effects of TNFα/ROs on mitochondrial function, ASK1-JNK/p38 cascade activation in intestinal epithelial cells during NEC.

    Full Text Available Necrotizing enterocolitis (NEC and spontaneous intestinal perforation (SIP are acute intestinal conditions which could result in mortality and severe morbidity in preterm infants. Our objective was to identify dysregulated micro-RNAs (miRNAs in small bowel tissues of NEC and SIP, and their possible roles in disease pathophysiology.We performed differential miRNA arrays on tissues of NEC (n = 4, SIP (n = 4 and surgical-control (Surg-CTL; n = 4, and validated target miRNAs by qPCR (n = 10 each group. The association of target miRNAs with 52 dysregulated mRNAs was investigated by bioinformatics on functional and base-pair sequence algorithms, and correlation in same tissue samples.We presented the first miRNA profiles of NEC, SIP and Surg-CTL intestinal tissues in preterm infants. Of 28 validated miRNAs, 21 were significantly different between NEC or SIP and Surg-CTL. Limited overlapping in the aberrant expression of miRNAs between NEC and SIP indicated their distinct molecular mechanisms. A proposed network of dysregulated miRNA/mRNA pairs in NEC suggested interaction at bacterial receptor TLR4 (miR-31, miR-451, miR-203, miR-4793-3p, mediated via key transcription factors NFKB2 (miR-203, AP-1/FOSL1 (miR-194-3p, FOXA1 (miR-21-3p, miR-431 and miR-1290 and HIF1A (miR-31, and extended downstream to pathways of angiogenesis, arginine metabolism, cell adhesion and chemotaxis, extracellular matrix remodeling, hypoxia/oxidative stress, inflammation and muscle contraction. In contrast, upregulation of miR-451 and miR-223 in SIP suggested modulation of G-protein-mediated muscle contraction.The robust response of miRNA dysregulation in NEC and SIP, and concerted involvement of specific miRNAs in the molecular networks indicated their crucial roles in mucosa integrity and disease pathophysiology.

    The reported incidence of necrotising enterocolitis in neonates with complex CHD with ductus-dependent systemic circulation ranges from 6.8 to 13% despite surgical treatment; the overall mortality is between 25 and 97%. The incidence of gastrointestinal complications after hybrid palliation for neonates with ductus-dependent systemic circulation still has to be defined, but seems comparable with that following the Norwood procedure. We reviewed the incidence of gastrointestinal complications in a series of 42 consecutive neonates with ductus-dependent systemic circulation, who received early hybrid palliation associated with a standardised feeding protocol. The median age and birth weight at the time of surgery were 3 days (with a range from 1 to 10 days) and 3.07 kg (with a range from 1.5 to 4.5 kg), respectively. The median ICU length of stay was 7 days (1-70 days), and the median hospital length of stay was 16 days (6-70 days). The median duration of mechanical ventilation was 3 days. Hospital mortality was 16% (7/42). In the postoperative period, 26% of patients were subjected to early extubation, and all of them received treatment with systemic vasodilatory agents. Feeding was started 6 hours after extubation according to a dedicated feeding protocol. After treatment, none of our patients experienced any grade of necrotising enterocolitis or major gastrointestinal adverse events. Our experience indicates that the combination of an "early hybrid approach", systemic vasodilator therapy, and dedicated feeding protocol adherence could reduce the incidence of gastrointestinal complications in this group of neonates. Fast weaning from ventilatory support, which represents a part of our treatment strategy, could be associated with low incidence of necrotising enterocolitis.

    Toll-like receptors are vital transmembrane receptors that initiate the innate immune response to many micro-organisms. The discovery of these receptors has improved our understanding of host-pathogen interactions, and these receptors play an important role in the pathogenesis of multiple neonatal conditions such as sepsis and brain injury. Toll-like receptors, especially TLRs 2 and 4, are associated with necrotizing enterocolitis, periventricular leukomalacia and sepsis.

    Necrotising enterocolitis (NEC) is one of the most common and serious acquired bowel diseases a premature newborn can face. This meta-analysis was performed comparing different probiotic mixtures to ascertain their benefits as a routine tool for preventing necrotising enterocolitis and reducing late-onset sepsis and mortality in premature neonates of less than 1500g. A systematic review of randomised controlled trials, between January 1980 and March 2014, on MEDLINE, the Cochrane Central Register of Controlled Trials, together with EMBASE, was carried out. Studies with infants Probiotics were found to reduce the NEC incidence (RR 0.39; 95%CI: 0.26-0.57) and mortality (RR 0.70; 95%CI: 0.52-0.93), with no difference to placebo regarding late-onset sepsis (RR 0.91; 95%CI: 0.78-1.06). Finally, when analysing the different strands, the use of a 2-probiotic combination (Lactobacillus acidophilus with Bifidobacterium bifidum) proved to be statistically significant in reducing all-cause mortality when compared to other probiotic combinations (RR 0.32; 95%CI: 0.15-0.66, NNT 20; 95%CI: 12-50). Probiotics are a beneficial tool in the prevention of NEC and mortality in preterm neonates. Moreover, the combination of 2 probiotics (Lactobacillus acidophilus with Bifidobacterium bifidum) seems to produce the greatest benefits. However, due to the differences in probiotic components and administration, it would be wise to perform a randomised controlled trial comparing different probiotic mixtures.

    Full Text Available The field of genomics has expanded into subspecialties such as metagenomics over the course of the last decade and a half. The development of massively parallel sequencing capabilities has allowed for increasingly detailed study of the genome of the human microbiome, the microbial super organ that resides symbiotically within the mucosal tissues and integumentary system of the human host. The gut microbiome, and particularly the study of its origins in neonates, have become subtopics of great interest within the field of genomics. This brief review seeks to summarize recent literature regarding the origins and establishment of the neonatal gut microbiome, beginning in utero, and how it is affected by neonatal nutritional status (breastfed versus formula fed and gestational age (term versus preterm. We also explore the role of dysbiosis, a perturbation within the fragile ecosystem of the microbiome, and its role in the origin of select pathologic states, specifically, obesity and necrotizing enterocolitis in preterm infants. We discuss the evidence supporting enteral pre- and probiotic supplementation of commensal organisms such as Bifidobacterium and Lactobacillus in the neonatal period, and their role in the prevention and amelioration of necrotizing enterocolitis in premature infants. Finally, we review directions to consider for further research to promote human health within this field.

    Enterocolic lymphocytic phlebitis is a rare cause of segmental ischemic enterocolitis. This artery-sparing transmural vasculitis is classically a circumferential phlebitis with perivenular lymphocyte cuffing and thrombi in the absence of systemic manifestations. Myointimal hyperplasia may represent a chronic phase of enterocolic lymphocytic phlebitis. Subclinical or early stage enterocolic lymphocytic phlebitis is not well delineated. We analyzed 600 submucosal and subserosal veins from both ischemic and intact bowel segments to discern if vascular morphology varied between sites. Crescentic and circumferential lymphocytic phlebitis is more common in viable bowel than in the ischemic segment. A nonsignificant trend was found for increased crescentic morphology between intact bowel remote from the ischemic focus compared with that adjacent to the ischemic focus. Hallmarks of ischemic bowel are necrotizing phlebitis and thrombi formation. Thrombophlebitis morphology is distinctly different in viable and ischemic bowel, changing from the classic lymphocytic to necrotizing lesions respectively.

    Full Text Available Samples of intestine with necrotic enteritis from 63 pigs naturally infected with porcine circovirus type 2 (PCV2 were studied. Colon was the main target of PCV2 associated necrotic enteritis in 60 cases. Immunohistological investigations were carried out to detect the presence of PCV2 in necrotic lesions and to identify the type of cells infected by the virus. Crypt epithelial cells had positive labelling for PCV2 in 17 cases. Depletion of goblet cells occurred in 10 cases. In 24 necrotic enteritis cases, co-infection of PCV2 and Salmonella was identified. An increased rate of apoptosis in the crypt epithelial cells of the large intestine from PCV2 of naturally infected pigs was observed. Immunohistochemical findings confirmed the presence of PCV2 within cells from necrotic intestinal tissue, suggesting that PCV2 may play a role in the development of those lesions. Diagnosis of necrotic enteritis associated with PCV2 should be based on the detection of PCV2 antigen or DNA in the necrotizing lesions. However, bacteriological examination should be performed to rule out the presence of bacterial agents, since co-infections are likely to occur in PCV2 affected pigs.Foram selecionadas amostras intestinais com enterite necrótica de 63 suínos naturalmente infectados pelo circovírus suíno tipo 2 (PCV2.

    Full Text Available Cow's milk allergic enterocolitis is a common paediatric gastrointestinal disease. However, radiological findings from contrast studies have rarely been reported. We report two Japanese neonate patients with cow's milk allergic enterocolitis with vomiting, bloody stool and unique findings on upper gastrointestinal contrast study. Upper gastrointestinal contrast study showed folds of the small intestine to be thickened, such as in spasm, or ribbonlike cords in both cases. There was also poor passage from the duodenum to the jejunum in one case. In addition, there were spastic findings on lower gastrointestinal contrast study in part of the large colon in one case. Clinicians, including paediatric surgeons, treating neonates with bloody stool and/or vomiting should thus be aware that unique findings on upper and lower gastrointestinal contrast studies may be useful in suspecting cases with cow's milk allergic enterocolitis.

    Conclusion: Abnormal brain sonography [odds ratio (OR: 2.222, p = 0.047 and necrotizing enterocolitis (NEC (OR: 2.857, p = 0.017 did affect the first trial in the study group. Early intervention of oral-motor management in very-low-birth-weight premature infants improved feeding performance and neonatal outcome in terms of shorter hospital days. Abnormal brain image and NEC could interfere with the success rate of initial challenge of transitioning from tube to oral feeding in the study group.

    In order to determine the factors related to mortality in Necrotizing enterocolitis (NEC), medical records of neonates and older infants diagnosed of NEC in the Instituto de Salud del Niño between 1984 and 1993 were retrospectively reviewed. Only the cases with a reliable roentgenologic, surgical or pathologic diagnosis were included. Sixty cases (46 infants and 14 neonates) were found, with a higher incidence in males (37 males vs 23 females). Twenty six cases required surgical treatment. Overall mortality was 77%, with no significant differences between neonates and infants, nor between those who were operated or not. Moderate or severe malnutrition, diarrhea as an early clinical manifestations, bronchopneumonia, shock and poor nutricional management were found as factors related to mortality.

  12. Neonatal Platelet Transfusions and Future Areas of Research.

    2016-10-01

    Thrombocytopenia affects approximately one fourth of neonates admitted to neonatal intensive care units, and prophylactic platelet transfusions are commonly administered to reduce bleeding risk. However, there are few evidence-based guidelines to inform clinicians' decision-making process. Developmental differences in hemostasis and differences in underlying disease processes make it difficult to apply platelet transfusion practices from other patient populations to neonates. Thrombocytopenia is a risk factor for common preterm complications such as intraventricular hemorrhage; however, a causal link has not been established, and platelet transfusions have not been shown to reduce risk of developing intraventricular hemorrhage. Platelet count frequently drives the decision of whether to transfuse platelets, although there is little evidence to demonstrate what a safe platelet nadir is in preterm neonates. Current clinical assays of platelet function often require large sample volumes and are not valid in the setting of thrombocytopenia; however, evaluation of platelet function and/or global hemostasis may aid in the identification of neonates who are at the highest risk of bleeding. Although platelets' primary role is in establishing hemostasis, platelets also carry pro- and antiangiogenic factors in their granules. Aberrant angiogenesis underpins common complications of prematurity including intraventricular hemorrhage and retinopathy of prematurity. In addition, platelets play an important role in host immune defenses. Infectious and inflammatory conditions such as sepsis and necrotizing enterocolitis are commonly associated with late-onset thrombocytopenia in neonates. Severity of thrombocytopenia is correlated with mortality risk. The nature of this association is unclear, but preclinical data suggest that thrombocytopenia contributes to mortality rather than simply being a proxy for disease severity. Neonates are a distinct patient population in whom

    Advances in diagnostic techniques and perioperative care have greatly improved the outcome of neonatal surgery. Despite this, disparity still exists in the outcome of neonatal surgery between developed and developing countries. We performed a prospective study of neonates admitted and treated due to surgical congenital diseases and other conditions in our hospital from April 2015 to April 2017. There were 19 (28,7%) females and 47 (70,3%) males in this group. It was found that 41 neonates had 7 days after birth or less by a 62% and 25 with more than 7 days by 38%. The Anorectal malformations (ARM) were the most frequent congenital anomaly in 21 patients (47%), followed by Gastroquises with 7 neonates (10,6%), Omphalocele with 8 (12%), and Oesophagus Atresia in 5 neonates (7,5%). Intestinal Malrotation with midgut volvulus, Pyloric Stenoses and Duodenal Atresia in 4 neonates (6,2 % each). Others alterations such as, Ileal Atresia, Strangulated Inguinal Hernia, Limb Gangrene, Necrotizing Enterocolitis, Sacro Coxigeal Theratoma, Megacolon Aganglionic, Colon perforation, Gastric perforation and Hydromethrocolpus accounted in 13 neonates by 19,7% from the total of patients. Ten babies died (15%). We conclude that Anorectal Malformations, Gastroquises and Omphalocele were the most frequent malformations. Considering the mortality is above the average of developed countries this could be improved by increasing the knowledge about the neonatal surgery characteristics among medical doctors and improving the necessary facilities and back up.

Women in acute preterm labor with cervical dilatation 1-6 cm were randomized to receive one of three first-line tocolytic drugs. There were 317 neonates (I = 103, M = 95, N = 119) whose mothers were treated with tocolytic therapy. There was no difference in gestational age at randomization (average 28.6 weeks' gestation) or at delivery (31.6 weeks' gestation, p = 0.551), birth weight (p = 0.871) or ventilator days (p = 0.089) between the three groups. Neonatal morbidity was not different between the three groups; respiratory distress syndrome (p = 0.086), patent ductus arteriosus (p = 0.592), sepsis (p = 0.590), necrotizing enterocolitis (p = 0.770), intraventricular hemorrhage (p = 0.669) and periventricular leukomalacia (p = 0.124). There were no statistically significant differences between the three tocolytics as far as composite neonatal morbidity or mortality was concerned.

    The study objective was to determine whether Ureaplasma respiratory tract colonization of preterm infants Ureaplasma culture and PCR were obtained during the first week of life from 368 infants Ureaplasma-positive (12.3%) than Ureaplasma-negative infants (5.5%) Ureaplasma-positive (14.6%) than Ureaplasma-negative (4.4%) infants ≤28 wks (OR 3.67, 95%CI 1.36-9.93, P=0.01). Age of onset, hematologic parameters at onset, and NEC severity were similar between Ureaplasma-positive and negative infants. Cord serum IL-6 and IL-1β concentrations were significantly higher in Ureaplasma-positive than in Ureaplasma-negative NEC-affected infants. Ureaplasma may be a factor in NEC pathogenesis in preterm infants by contributing to intestinal mucosal injury and/or altering systemic or local immune responses. PMID:21258263

    Objective To estimate the association between maternal super obesity (body mass index [BMI] ≥ 50 kg/m(2)) and neonatal morbidity among neonates born via cesarean delivery (CD). Methods Retrospective cohort of singleton neonates delivered via CD ≥ 37 weeks in the Maternal-Fetal Medicine Unit Cesarean Registry. Maternal BMI at delivery was stratified as 18.5 to 29.9 kg/m(2), 30 to 39.9 kg/m(2), 40 to 49.9 kg/m(2), and ≥ 50 kg/m(2). Primary outcomes included acute (5-minute Apgar score neonatal injury, and/or transient tachypnea of the newborn) and severe (grade 3 or 4 intraventricular hemorrhage, necrotizing enterocolitis, seizure, respiratory distress syndrome, hypoxic ischemic encephalopathy, meconium aspiration, ventilator support ≥ 2 days, sepsis and/or neonatal death) neonatal morbidity. Odds of neonatal morbidity were estimated for each BMI category adjusting for clinical and operative characteristics. Results Of 41,262 maternal-neonatal dyads, 36% of women were nonobese, 49% had BMI of 30 to 39.9 kg/m(2), 12% had BMI of 40 to 49.9 kg/m(2), and 3% were super obese. Compared with nonobese women, super obese women had twofold odds of acute (5 vs. 10%; adjusted odds ratio [aOR]: 1.81, 95% confidence interval [CI]: 1.59-2.73) and severe (3 vs. 6%; aOR: 2.08; 95% CI: 1.59-2.73) neonatal morbidity. Conclusion Among term infants delivered via CD, maternal super obesity is associated with increased risk of neonatal morbidity. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Pentraxin 3 (PTX3) is an acute phase reactant which has been used to detect intra-amniotic infections (IAI) in pregnancy, but the prognostic value of PTX3 concentrations on neonates has not been studied. We aimed to investigate the relationship between maternal PTX3-neonatal PTX3 concentrations and early neonatal outcome. The mothers diagnosed with preterm prelabor rupture of membranes (PPROM) (n = 28) and their preterm infants (n = 28) were included in the study. PTX3 concentrations were studied in plasma in the maternal peripheral blood and umbilical/peripheral vein in the neonates. The relationship between the mPTX3-nPTX3 concentrations and neonatal outcome were investigated using non-parametric tests and binary logistic regression analysis. The mean mPTX3 concentration was 10.35 ± 7.82 μg/L. Ten (35.7%) of all mothers were within the normal range and 18 (64.3%) in high percentile (≥ 97.5 percentile). There was no relation between mPTX3 concentrations and clinical or histologic chorioamnionitis, latency of PPROM, and early neonatal outcome. Mean nPTX3 concentrations was 9.18 ± 7.83 μg/L and high nPTX3 concentrations were detected in five (17.8%) neonates. nPTX3 concentrations were inversely correlated with gestational age and correlated with rate of intraventricular hemorrhage (IVH) and mortality. Neonates with high nPTX3 concentrations also have lowered APGAR scores, increased rate of respiratory distress syndrome, clinical sepsis, IVH, necrotizing enterocolitis and prolonged NICU stay. High PTX3 concentrations of the newborns are associated with some worsened early neonatal outcome including lower gestational age at delivery, increased rate of IVH and mortality. Maternal PTX3 concentrations are not an adequate marker in defining clinical or histologic chorioamnionitis and early neonatal outcome.

    The factors that contribute to the development of acute kidney injury (AKI) and treatment outcome among prematurely born neonates are not clearly understood. This retrospective study included 150 prematurely born neonates. AKI was defined as an increase of serum creatinine levels ≥0.3 mg/dl compared to basal values. The majority of neonates with AKI (94.8 %) had a body weight 5 on the first day of life, core body temperature hemorrhage, necrotizing enterocolitis, patent ductus arteriosus, as well as a treatment with vancomycin or dopamine were independent risk factors for the development of AKI. After the groups of neonates with and without AKI were adjusted, the calculated risk ratio for a negative outcome of treatment (death) was 2.215 (CI 1.27-3.86) for neonates with AKI. Neonates with AKI had higher serum sodium levels in the third and fourth days of life. AKI is associated with high mortality in preterm neonates. It is very important to identify, as quickly as possible, all infants who are at high risk of developing AKI.

    Histologic chorioamnionitis (HCA) is commonly associated with preterm birth and deleterious post-natal outcomes including sepsis and necrotizing enterocolitis. Transcriptomic analysis has been used to uncover gene signatures that permit diagnosis and prognostication, show new therapeutic targets, and reveal mechanisms that underlie differential outcomes with other complex disease states in neonates such as sepsis. To define the transcriptomic and inflammatory protein response in peripheral blood among infants with exposure to histologic chorioamnionitis. Prospective, observational study. Uninfected preterm neonates retrospectively categorized based on placental pathology with no HCA exposure (n=18) or HCA exposure (n=15). We measured the transcriptomic and inflammatory mediator response in prospectively collected whole blood. We found 488 significant (p<0.001), differentially expressed genes in whole blood samples among uninfected neonates with HCA exposure that collectively represented activated innate and adaptive immune cellular pathways and revealed a potential regulatory role for the pleotropic microRNA molecule miR-155. Differentially secreted plasma cytokines in patients with HCA exposure compared to patients without HCA included MCP-1, MPO, and MMP-9 (p<0.05). Exposure to HCA distinctively activates the neonatal immune system in utero with potentially long-term health consequences. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The annual volume of deliveries of very low-birth-weight (VLBW) infants has a greater effect on mortality risk than does neonatal intensive care unit (NICU) level. The differential effect of these hospital factors on morbidity among VLBW infants is uncertain. To assess the independent effects of a birth hospital's annual volume of VLBW infant deliveries and NICU level on the risk of several neonatal morbidities and morbidity-mortality composite outcomes that are predictive of future neurocognitive development. Retrospective, population-based cohort study (performed in 2014) of all VLBW infants without severe congenital anomalies delivered in all hospitals in California, Missouri, and Pennsylvania between January 1, 1999, and December 31, 2009 (N = 72,431). Risk-adjusted odds ratios and risk-adjusted probabilities were determined by logistic regression. The primary study outcomes were the individual composites of death or bronchopulmonary dysplasia, necrotizing enterocolitis, retinopathy of prematurity, and severe intraventricular hemorrhage. Among the 72,431 VLBW infants in the present study, birth at a hospital with 10 or less deliveries of VLBW infants per year was associated with the highest risk-adjusted probability of death (15.3% [95% CI, 14.4%-16.3%]), death or severe intraventricular hemorrhage (17.5% [95% CI, 16.5%-18.6%]), and death or necrotizing enterocolitis (19.3% [95% CI, 18.1%-20.4%]). These complications were also more common among infants born at hospitals with a level I or II NICU compared with infants delivered at hospitals with a level IIIB/C NICU. The risk-adjusted probability of death or retinopathy of prematurity was highest among infants born at hospitals with a level IIIB/C NICU and lowest among infants born at hospitals with a level IIIA NICU. When the effects of NICU level and annual volume of VLBW infant deliveries were evaluated simultaneously, the annual volume of deliveries was the stronger contributor to the risk of death, death or

    We wanted to evaluate the clinical efficacy of an increased computed tomography attenuation coefficient (CTAC) of urine after the oral administration of iohexol in neonates who are suspected of suffering with neonatal necrotizing enterocolitis (NEC). During a recent 1 year-period, seventeen neonates were admitted for suspected NEC, and they were divided into the suspected and definite groups based on their clinical signs and radiographic findings; we also included ten normal neonates as the control group. Diluted iohexol was administered and the CTACs of collected urine samples at 8-12 hour intervals were measured. Comparative analysis of the three groups was done and statistical significance was determined by the Scheffe test. Among 17 neonates, there were 13 neonates in the suspect group and 4 neonates in the definite group. The mean CTACs of urine in each group were 2711 HU (control group), 3411 HU (suspected group), and 7625 HU (definite group), respectively. There was a significant difference between the mean CTAC of the definite group and that of the control or suspected groups (Scheffe t >2.65). However, no statistically significant difference was seen between the suspected and control groups (Scheffe t=1.14). Although measurements of the CTAC of urine showed no significant diagnostic efficacy in the suspected group, the CTAC of urine, which reflects the correlated degree of bowel mucosal injury, can be a useful aid for determining the severity and progression of NEC

    Radiotherapy for malignant tumors is effective and established. However, there are many complications in radiotherapy. A typical complication is radiation enterocolitis. It is difficult to treat severe histological damage to the irradiated tissues. This paper reports our experience with 26 patients with radiation enterocolitis for whom surgical treatment was given during a period of 16 years in our surgical department. The most frequent original disease requiring irradiation was cancer of the cervix uteri (15 cases) which was followed by cancer of the urinary bladder (7 cases). All of these patients had received external 60 Co irradiation. The ileum was the most frequent site of the lesion, followed by the rectum, sigmoid and descending colon. The period between the end of irradiation and the onset of enterocolitis ranged from 2 months to 10 years, with an average of 28 months. The main symptoms were intestinal obstruction in the ileum, and melena and fistula in the rectum and sigmoid colon. Intestinal resection was performed in 10 patients, a bypass operation in 4, and colostomy in 12. As to types of intestinal suture in these cases, Gambee's single layer method was thought useful from our experience. Colostomy as surgical management of melena and fistula did not yield satisfactory results. (author)

    Enterocolic lymphocytic phlebitis (ELP) is a recently described entity and is of unknown etiology and pathogenesis. It is characterized by phlebitis of the bowel wall and mesentery, without arterial involvement or evidence of systemic vasculitis. The clinical presentation of ELP is varied, but it most commonly manifests with signs of an acute abdomen. Clinical, radiologic, and endoscopic findings are often conflicting and misdiagnosis is common as venous thrombosis is not suspected. The diagnosis of ELP is obtained histologically. There is a spectrum of histologic features associated with ELP, which includes lymphocytic phlebitis, necrotizing phlebitis, granulomatous phlebitis, and myointimal hyperplasia. Other features include venous thrombi and acute ischemic changes of the intestine. Surgical resection of the affected bowel is usually curative and recurrences are rare. The clinical and histopathologic features of ELP are reviewed.

    Retinopathy of prematurity (ROP) is a serious problem of preterm infants which may lead to impairment of vision and even to blindness if untreated. Routine eye examination is necessary for early diagnosis and treatment of ROP in preterm infants. Mydriatic eye drops (cyclopentolate, tropicamide and phenylephrine) are applied before the ophthalmic examination. These agents are rarely absorbed to systemic circulation and in some cases result with serious side effects like skin rash, tachycardia, feeding intolerance, discomfort, apnea, gastric dilatation and ileus, despite different treatment models and dosage reducing strategies. We report here a preterm patient who died because of severe diffuse necrotizing enterocolitis (NEC) after topical application of 0.5% cyclopentolate and 1.25% phenylephrine during ROP screening to emphasise the serious side effects of these agents.

    The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology. EA was administered by caudal puncture and epidural catheter placed with ultrasound support. Levobupivacaine was selected as anesthetic drug. The time to extubation, intestinal transit time, type of analgesia and complications were studied. This study is based on 11 cases (2 esophageal atresia, 2 diaphragmatic hernias, 1 necrotizing enterocolitis, 3 intestinal atresia, 2 anorectal malformation and 1 bladder exstrophy) and 22 controls. We observed statistically significant differences in time to extubation (95% CI OR 12 1.99 to 72.35; Chi2 p = 0.004, Mann U Whytney p = 0.013) and intestinal transit time (Mann Whitney U p analgesia. Therefore we believe that the intra-and postoperative EA helps improve postoperative management in neonates and should be preferred in centers where this technique is available.

    Full Text Available OBJECTIVE: Anesthetic and operative interventions in neonates remain hazardous procedures, given the vulnerability of the patients in this pediatric population. The aim was to determine the preoperative and intraoperative factors associated with 30-day post-operative mortality and describe mortality outcomes following neonatal surgery under general anesthesia in our center. METHODS: Infants less than 28 days of age who underwent general anesthesia for surgery during an 11-year period (2000 - 2010 in our tertiary care pediatric center were retrospectively identified using the pediatric intensive care unit database. Multiple logistic regression was used to identify independent preoperative and intraoperative factors associated with 30-day post-operative mortality. RESULTS: Of the 437 infants in the study (median gestational age at birth 37 weeks, median birth weight 2,760 grams, 28 (6.4% patients died before hospital discharge. Of these, 22 patients died within the first post-operative month. Logistic regression analysis showed increased odds of 30-day post-operative mortality among patients who presented American Society of Anesthesiologists physical status (ASA score 3 or above (odds ratio 19.268; 95%CI 2.523 - 147.132 and surgery for necrotizing enterocolitis/gastrointestinal perforation (OR 5.291; 95%CI 1.962 - 14.266, compared to those who did not. CONCLUSION: The overall in-hospital mortality of 6.4% is within the prevalence reported for developed countries. Establishing ASA score 3 or above and necrotizing enterocolitis/gastrointestinal perforation as independent risk factors for early mortality in neonatal surgery may help clinicians to more adequately manage this high risk population.

    A multidisciplinary committee composed of a panel of experts, including a member of the American Academy of Pediatrics and American Institute of Architects, has suggested that the delivery room (DR) and the neonatal intensive care units (NICU) room should be directly interconnected. We aimed to investigate the impact of the architectural design of the DR and the NICU on neonatal outcome. Two cohorts of preterm neonates born at architectural renovation of the DR realized in accordance with specific standards (Cohort 2: "new concept of DR"). In Cohort 1, neonates were initially cared for a conventional resuscitation area, situated in the DR, and then transferred to the NICU, located on a separate floor of the same hospital. In Cohort 2 neonates were assisted at birth directly in the NICU room, which was directly connected to the DR via a pass-through door. The primary outcome of the study was morbidity, defined by the proportion of neonates with at least one complication of prematurity (i.e., late-onset sepsis, patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity and necrotizing enterocolitis). Secondary outcomes were mortality and duration of hospitalization. Statistical analysis was performed using standard methods by SPSS software. We enrolled 106 neonates (56 in Cohort 1 and 50 in Cohort 2). The main clinical and demographic characteristics of the 2 cohorts were similar. Moderate hypothermia (body temperature ≤ 35.9 °C) was more frequent in Cohort 1 (57%) compared with Cohort 2 (24%, p = 0.001). Morbidity was increased in Cohort 1 (73%) compared with Cohort 2 (44%, p = 0.002). No statistically significant differences in mortality and median duration of hospitalization were observed between the 2 cohorts of the study. If realized according to the proposed architectural standards, renovation of DR and NICU may represent an opportunity to reduce morbidity in preterm neonates.

    Improvements in neonatal care over the past 3 decades have increased survival of infants at lower birthweights and gestational ages. However, outcomes and practices vary considerably between hospitals. To describe maternal and infant characteristics, neonatal intensive care units (NICU) practices, morbidity, and mortality in Wisconsin NICUs, and to compare outcomes in Wisconsin to the National Institute of Child Health and Human Development network of large academic medical center NICUs. The Newborn Lung Project Statewide Cohort is a prospective observational study of all very low birthweight (< or =1500 grams) infants admitted during 2003 and 2004 to the 16 level III NICUs in Wisconsin. Anonymous data were collected for all admitted infants (N=1463). Major neonatal morbidities, including bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP) were evaluated. The overall incidence of BPD was 24% (8%-56% between NICUs); IVH incidence was 23% (9%-41%); the incidence of NEC was 7% (0%-21%); and the incidence of grade III or higher ROP was 10% (0%-35%). The incidence rates of major neonatal morbidities in Wisconsin were similar to those of a national network of academic NICUs.

    Survival of very-low-birth-weight infants (VLBWI) depends on professional perinatal management that begins at delivery. Korean Neonatal Network data on neonatal resuscitation management and initial care of VLBWI of less than 33 weeks gestation born from January 2013 to June 2014 were reviewed to investigate the current practice of neonatal resuscitation in Korea. Antenatal data, perinatal data, and short-term morbidities were analyzed. Out of 2,132 neonates, 91.7% needed resuscitation at birth, chest compression was performed on only 104 infants (5.4%) and epinephrine was administered to 80 infants (4.1%). Infants who received cardiac compression and/or epinephrine administration at birth (DR-CPR) were significantly more acidotic (P CPR resulted in greater early mortality of less than 7 days (OR, 5.64; 95% CI 3.25-9.77) increased intraventricular hemorrhage ≥ grade 3 (OR, 2.71; 95% CI 1.57-4.68), periventricular leukomalacia (OR, 2.94; 95% CI 1.72-5.01), and necrotizing enterocolitis (OR, 2.12; 95% CI 1.15-3.91) compared with those infants who needed only PPV. Meticulous and aggressive management of infants who needed DR-CPR at birth and quality improvement of the delivery room management will result in reduced morbidities and early death for the vulnerable VLBWI.

    We reviewed 17 cases of severe radiation enterocolitis caused by tele-cobalt treatment for pelvic malignancies. They consisted of six males and nine females, ranging from 32 to 77 years old. The duration between the completion of radiation and the onset of symptoms varied from two months to ten years. Only two cases of them were treated conservatively and the other 15 cases were managed surgically. Six cases of the latter underwent an urgent surgery because of severe obstructive symptoms. Totally, 19 injuries to the intestine were revealed. The ileum was involved in eight patients, the rectum in seven and the sigmoid colon in four. Operative procedures carried out were intestinal resection with primary anastomosis in seven, colostomy alone in six and bypass operation in three. The resected segments of the ileum measured 40 cm long in two and 70 cm, 90 cm and 100 cm long in three respectively and the resected segments of the colon measured 15 cm and 45 cm long respectively. Three out of the seven cases with bowel resection were reconstructed with Gambee's single layer anastomosis and four with Albert-Lembert's two layer anastomosis. Type of anastomosis was end-to-end in six and end-to-side in one. Three cases underwent bypass operations because the injured intestines were densely adhered to the surroundings. Only one minor leakage occurred in seven primary anastomosis. Radiation doses ranged from 3000 to 9300 R. There was no relation between doses and severity of damage, clinical symptoms and site of injuries. There was no malignant findings around the damaged intestine. Many of the literatures report a high anastomotic leak in radiation enterocolitis, primary anastomosis can be carried out more safely if wide resection and reasonable anastomosis are performed.

    BACKGROUND: Routine care for chylothorax in neonate includes either conservative or surgical approaches. Octreotide, a somatostatin analogue, has been used for the management of patients with refractory chylothorax not responding to conservative management. OBJECTIVES: To assess the efficacy and safety of octreotide in the treatment of chylothorax in neonates. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (to March 7, 2010). We assessed the reference lists of identified trials and abstracts from the annual meetings of the Pediatric Academic Societies published in Pediatric Research (2002 to 2009) without language restrictions. SELECTION CRITERIA: We planned to include randomised or quasi-randomised controlled trials of octreotide in the treatment of congenital or acquired chylothorax in term or preterm neonates, with any dose, duration or route of administration. DATA COLLECTION AND ANALYSIS: Data on primary (amount of fluid drainage, respiratory support, mortality) and secondary outcomes (side effects) were planned to be collected and analysed using mean difference, relative risk and risk difference with 95% confidence intervals. MAIN RESULTS: No randomised controlled trials were identified. Nineteen case reports of 20 neonates with chylothorax in whom octreotide was used either subcutaneously or intravenously were identified. Fourteen case reports described successful use (resolution of chylothorax), four reported failure (no resolution) and one reported equivocal results following use of octreotide. The timing of initiation, dose, duration and frequency of doses varied markedly. Gastrointestinal intolerance and clinical presentations suggestive of necrotizing enterocolitis and transient hypothyroidism were reported as side effects. AUTHORS\\' CONCLUSIONS: No practice recommendation can be made based on the evidence identified in this review. A prospective registry of

Nasogastric feeding tubes (NG-tubes) might contaminate feeds given through them due to biofilm formation. We wanted to determine if there is a rationale in replacing NG......-tubes more often to reduce contamination. METHODS: We conducted an observational study of used NG-tubes from a tertiary neonatal department. After removal, we flushed a 1-ml saline solution through the tube, determined the density of bacteria by culture, and related it to the duration of use and any...

    Necrotizing enterocolitis is the most frequently occurring gastrointestinal disorder in premature neonates. Animal models of necrotizing enterocolitis and prenatal administration of cortisone have demonstrated that cortisone may accelerate maturation of the mucosal barrier, therefore reducing the incidence of this gastrointestinal disorder.

    Ureaplasma species (spp.) have been acknowledged as major causative pathogens in chorioamnionitis and prematurity, but may also contribute to key morbidities in preterm infants. Several epidemiological and experimental data indicate an association of neonatal Ureaplasma colonization and/or infection with bronchopulmonary dysplasia. Furthermore, a potential causal relation with other inflammation-induced morbidities, such as intraventricular hemorrhage, white matter injury, necrotizing enterocolitis, and retinopathy of prematurity, has been debated. Areas covered: This review will summarize current knowledge on the role of Ureaplasma spp. in prenatal, perinatal, and neonatal morbidities, while furthermore examining mutual underlying mechanisms. We try to elaborate who is at particular risk of Ureaplasma-induced inflammation and subsequent secondary morbidities. Expert commentary: Most likely by complex interactions with immunological processes, Ureaplasma spp. can induce pro-inflammation, but may also downregulate the immune system. Tissue damage, possibly causing the above mentioned complications, is likely to result from both ways: either directly cytokine-associated, or due to a higher host vulnerability to secondary impact factors. These events are very likely to begin in prenatal stages, with the most immature preterm infants being most susceptible and at highest risk.

    To test if there is a stepwise difference in neonatal outcomes according to the stage (or grade) of histological inflammatory response in the chorioamniotic membranes and umbilical cords of preterm premature rupture of membranes (PPROM). This retrospective study included singleton pregnancies diagnosed as PPROM and delivered prior to 34 weeks of gestation (n=339). Acute histological chorioamnionitis and funisitis were subdivided into stages (or grade) as defined by Redline et al. Neonatal composite morbidities and mortality were also monitored. Univariate and multivariate analyses were conducted. Increasing stage (or grade) of acute histological chorioamnionitis and funisitis was significantly associated with an earlier gestational age at membrane rupture and delivery. Among neonatal outcomes, respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), intraventricular hemorrhage, retinopathy of prematurity, and composite morbidity showed incremental incidence according to increased stage (or grade) of acute chorioamnionitis, while periventricular leukomalacia and necrotizing enterocolitis did not. Only RDS, BPD, and composite morbidity showed similar incremental incidences associated with severity of funisitis stage. However, the incremental trends of each neonatal outcome were found to be nonsignificant by multivariate analysis adjusting confounding variables including gestational age at delivery. Higher incidences of neonatal morbidity according to increased stage (or grade) of either acute histological chorioamnionitis or funisitis were due to an earlier gestational age at delivery.

    This historical cohort study aimed to assess the relationship between antenatal maternal C-reactive protein (CRP) level and neonatal outcome preterm premature rupture of membranes (PPROM). We reviewed the records of 70 singleton pregnancies with PPROM between 24 and 34 weeks. Maternal CRP levels of neonates with respiratory distress syndrome, neonatal sepsis, grade 3-4 intraventricular haemorrhage and stage 2-3 necrotizing enterocolitis, perinatal mortality were compared with those without these complications. Administration of corticosteroid, tocolysis for two days and prophylactic antibiotics (intravenous ampicillin/sulbactam, and oral azithromycin) were the standard management protocol. The mean age at PPROM was 29 weeks 2 days (±3 weeks), the mean age at birth was 30 weeks 5 days (±20 days). CRP levels were not different between groups. Uni/multivariate analysis showed that maternal CRP levels were not related with neonatal outcomes. Neonatal complications in PPROM are related with the degree of prematurity and maternal WBC counts.

    Objective: To determine the extent of morbidity and mortality in newborns with neonatal hyperglycemia where published data are limited. Study Design: Observational case control study. Place and Duration of Study: Department of Neonatology, the Children'Hospital and the Institute of Child Health Lahore, from 1st May to 31st Oct 2015. Material and Methods: A prospective, observational case control study was conducted in the Department of Neonatology, the Children'Hospital and the Institute of Child Health, Lahore, from 1st May till 31st October 2015. The sample size was 192, with 96 babies each in ‘study’ and ‘control’ groups. All neonates fulfilling the inclusion criteria were enrolled in the ‘study group’ while ‘control group’ consisted of euglycemic babies matched for age, weight, gestational age and clinical status. All babies were monitored for morbidity intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), infections and outcome (duration of hospital stay, discharged or expired). Results: The data analysis showed that 74 percent neonates, of study group, had hyperglycemia during first week of their lives. Moreover, 84.4 percent babies were less than 2.5 kg. Significant high number of babies in the study group developed complications (p<0.001). These complications included IVH (p<0.001), NEC (p=0.024) and infections (p=0.019). As regards outcome, the neonates in the study group had significantly prolonged hospital stay (p=0.028), lower discharge rate (p=0.040) and higher mortality (p=0.040). Conclusion: Hyperglycemia not only significantly increases risk of IVH, NEC and infections, but also prolongs hospital stay and contributes to mortality among newborns. (author)

    Teduglutide, a synthetic glucagon-like peptide-2 (GLP-2) analog with activity relating to the regeneration, maintenance, and repair of the intestinal epithelium, is currently being evaluated for the treatment of short-bowel syndrome (SBS), Crohn's disease, and other gastrointestinal disorders. On the basis of promising results from teduglutide studies in adults with SBS and from studies in neonatal and juvenile animal models, a pediatric multiple-dose phase I clinical study was designed to determine the safety, efficacy, and pharmacokinetics of teduglutide in pediatric patients with SBS who have undergone resection for necrotizing enterocolitis, malrotation, or intestinal atresia. This report details the application of clinical trial simulations coupled with a novel approach using generalized additive modeling for location, scale, and shape (GAMLSS) that facilitates the simulation of demographic covariates specific to the targeted patient populations. The goal was to optimize phase I dosing strategies and the likelihood of achieving target exposure and therapeutic effect.

    Full Text Available Abstract Background Despite widespread use of neonatal hospital discharge data, there are few published reports on the accuracy of population health data with neonatal diagnostic or procedure codes. The aim of this study was to assess the accuracy of using routinely collected hospital discharge data in identifying neonatal morbidity during the birth admission compared with data from a statewide audit of selected neonatal intensive care (NICU admissions. Methods Validation study of population-based linked hospital discharge/birth data against neonatal intensive care audit data from New South Wales, Australia for 2,432 babies admitted to NICUs, 1994–1996. Sensitivity, specificity and positive predictive values (PPV with exact binomial confidence intervals were calculated for 12 diagnoses and 6 procedures. Results Sensitivities ranged from 37.0% for drainage of an air leak to 97.7% for very low birthweight, specificities all exceeded 85% and PPVs ranged from 70.9% to 100%. In-hospital mortality, low birthweight (≤1500 g, retinopathy of prematurity, respiratory distress syndrome, meconium aspiration, pneumonia, pulmonary hypertension, selected major anomalies, any mechanical ventilation (including CPAP, major surgery and surgery for patent ductus arteriosus or necrotizing enterocolitis were accurately identified with PPVs over 92%. Transient tachypnea of the newborn and drainage of an air leak had the lowest PPVs, 70.9% and 83.6% respectively. Conclusion Although under-ascertained, routinely collected hospital discharge data had high PPVs for most validated items and would be suitable for risk factor analyses of neonatal morbidity. Procedures tended to be more accurately recorded than diagnoses.

FONTES DE DADOS: Livros-textos e publicações indexadas no Medline e SciELO nos últimos 20 anos, utilizando-se as palavras chaves: "mesenteric artery", "superior mesenteric artery", "newborn intestinal circulation", "necrotizing enterocolitis", "doppler flow velocimetry". SÍNTESE DOS DADOS: Alterações do fluxo sanguíneo mesentérico são um dos fatores predisponentes da enterocolite necrosante, doença neonatal de alta morbimortalidade que acomete principalmente prematuros. A circulação mesentérica é peculiar no período neonatal tanto em relação ao seu estado basal, quanto à sua resposta frente a estímulos fisiológicos. Variações da irrigação mesentérica podem ser inerentes à própria fase de desenvolvimento vascular intestinal do recém-nascido pré-termo, com possíveis agravos de fatores perinatais como: insuficiência placentária, asfixia, infecção, cateterismo umbilical, drogas (indometacina e cafeína, fototerapia, alimentação artificial e progressão rápida da dieta. A dopplerfluxometria permite o estudo da irrigação de órgãos-alvo e pode quantificar o fluxo sanguíneo, a resistência vascular e predizer situações de risco para doenças do trato gastrintestinal no período neonatal. CONCLUSÕES: O recém-nascido apresenta peculiaridades de irrigação sanguínea gastrintestinal.

    Full Text Available Vitamin E (alpha-tocopherol is a potent and natural antioxidant. Vitamin E is concentrated from soybean oil. The Committee on Fetus and Newborn of the Academy of the American of Pediatrics endorsed 1 to 2 mg/dl as the normal range of serum tocopherol level. Human infants are born with low stores of vitamin E, thus they require an adequate intake of vitamin E soon after birth. The optimum intravenous dose of vitamin E is 2.8 mg/kg per day (maximum 7 mg/kg per day. Treating very-low-birth-weight infants with 100 mg/kg vitamin E for >1 week results in levels >3.5 mg/dl and significantly reduces the risks of severe retinopathy, intracranial hemorrhage, hemolytic anemia, chronic lung disease, retrolental fibroplasia and incidence and severity of intraventricular hemorrhage, but increases the risks of sepsis, necrotizing enterocolitis and can cause retinal hemorrhage in very-low-birth-weight infants. Vitamin E supplementation prevents the isolated vitamin E deficiency that causes spinocerebellar symptoms. The major benefits arising from elevated dosages of vitamin E have been the relief of symptoms of vitamin E deficiency in infants with abetalipoproteinamia and chronic cholestasis. Excessive doses of vitamin E may result in side effects and careful monitoring of vitamin E is thus essential. Neonates born to mothers treated with high doses of vitamin E have significantly lower birth weight compared to neonates born to untreated mothers. Vitamin E is not teratogenic. The aim of this study was to review the effects of vitamin E in neonates and young infants.

Se realizó un estudio retrospectivo de los 63 pacientes fallecidos por ECN durante un período de 25 años en el Hospital Pediátrico Docente "Centro Habana", donde se encontró que 71,4 % de los afectados eran de la raza blanca y el 68,2 % del sexo masculino. La edad más frecuente se halló en los menores de 3 meses de edad (36,5 % y el 46 % del total de la muestra estudiada tuvo un peso al nacer inferior a los 1 500 g. La prematuridad apareció asociada en el 55,5 % de los fallecidos y el 65 % tuvo lactancia mixta desde el momento de nacimiento.Necrotizing enterocolitis (NEC is a multifactorial caused gastrointestinal urgency closely related to the preterm newborn. Its high mortality has roots in the lack of prevention by the physician at any level of care, and due to a late diagnosis in risk groups. A retrospective study was carried out about 63 deceased patients as a result of NEC, along a 25 years period at the Centro Habana Teaching Pediatric Hospital, and it was found that 71,4 % of the affected infants were white, and that 68,2 % were masculin. The most frequent age was found in infants less than 3 months old (36,5 %, and 46 % of the total sample investigated had a birth weight lower than 1 500 g.

    Full Text Available History of present illness: A 71-year-old woman with a history of metastatic ovarian cancer presented with sudden onset, rapidly progressing painful rash in the genital region and lower abdominal wall. She was febrile to 103°F, heart rate was 114 beats per minute, and respiratory rate was 24 per minute. Her exam was notable for a toxic-appearing female with extensive areas of erythema, tenderness, and induration to her lower abdomen, intertriginous areas, and perineum with intermittent segments of crepitus without hemorrhagic bullae or skin breakdown. Significant findings: Computed tomography (CT of the abdominal and pelvis with intravenous (IV contrast revealed inflammatory changes, including gas and fluid collections within the ventral abdominal wall extending to the vulva, consistent with a necrotizing soft tissue infection. Discussion: Necrotizing fasciitis is a serious infection of the skin and soft tissues that requires an early diagnosis to reduce morbidity and mortality. Classified into several subtypes based on the type of microbial infection, necrotizing fasciitis can rapidly progress to septic shock or death if left untreated.1 Diagnosing necrotizing fasciitis requires a high index of suspicion based on patient risk factors, presentation, and exam findings. Definitive treatment involves prompt surgical exploration and debridement coupled with IV antibiotics.2,3 Clinical characteristics such as swelling, disproportionate pain, erythema, crepitus, and necrotic tissue should be a guide to further diagnostic tests.4 Unfortunately, lab values such as white blood cell count and lactate imaging studies have high sensitivity but low specificity, making the diagnosis of necrotizing fasciitis still largely a clinical one.4,5 CT is a reliable method to exclude the diagnosis of necrotizing soft tissue infections (sensitivity of 100%, but is only moderately reliable in correctly identifying such infections (specificity of 81%.5 Given the emergent

    Maternal obesity is associated with increased systemic inflammation and an increased risk of preterm premature rupture of membranes. There is an established association between an inflammatory intrauterine environment and adverse neonatal outcomes that is independent of gestational age and mediated by the fetal inflammatory response. It is unknown whether the maternal systemic inflammation that is present in obese women influences the intrauterine environment and predisposes the fetus to adverse neonatal outcomes after preterm premature rupture of membranes. The purpose of this study was to determine whether maternal obesity is associated with adverse neonatal outcomes in pregnancies that are complicated by preterm premature rupture of membranes. This was a secondary analysis of the Maternal-Fetal Medicine Units Network Randomized Clinical Trial on the Beneficial Effects of Antenatal Magnesium Sulfate. Women with singleton pregnancies that were affected by preterm premature rupture of membranes who delivered live-born infants between 24 + 0 and 33 + 6 weeks of gestation were included. An adverse neonatal outcome was defined as a composite outcome of neonatal death, severe necrotizing enterocolitis, respiratory distress syndrome, sepsis, or severe intraventricular hemorrhage. The rates of the composite outcome were compared between obese (body mass index, ≥30 kg/m(2)) and nonobese women. Multivariable logistic regression was used to evaluate the independent effect of obesity on neonatal outcomes. Magnesium sulfate administration, steroid administration, maternal diabetes mellitus, gestational age at delivery, indomethacin exposure, birthweight, and chorioamnionitis were all considered as possible covariates in the multivariable regression models. Three hundred twenty-five of the 1288 women (25.2%) who were included were obese, and 202 of these women (62.2%) had neonates with adverse outcomes. In univariable analysis, maternal prepregnancy obesity was associated

    Despite substantial progress in neonatal care over the past two decades leading to improved survival of extremely premature infants, extreme prematurity continues to be associated with long term neurodevelopmental impairments. Cerebral white matter injury is the predominant form of insult in preterm brain leading to adverse neurological consequences. Such brain injury pattern and unfavorable neurologic sequelae is commonly encountered in premature infants exposed to systemic inflammatory states such as clinical or culture proven sepsis with or without evidence of meningitis, prolonged mechanical ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis and chorioamnionitis. Underlying mechanisms may include cytokine mediated processes without direct entry of pathogens into the brain, developmental differences in immune response and complex neurovascular barrier system that play a critical role in regulating the cerebral response to various systemic inflammatory insults in premature infants. Understanding of these pathologic mechanisms and clinical correlates of such injury based on serum biomarkers or brain imaging findings on magnetic resonance imaging will pave way for future research and translational therapeutic opportunities for the developing brain.

    Denying parents access to their infant in the Neonatal Intensive Care Unit (NICU) is a standard practice in most hospitals across China. Visitation is not usually permitted or may be strictly limited, and NICU care for most neonates is provided by health-care professionals with little participation of the parents. An exception to this rule is the level 2 "Room-In" ward in Qilu Children's Hospital, Shandong University, where parents have 24-hour access to their infants and participate in providing care. This retrospective cohort study compared the outcomes of infants who were admitted to the NICU and remained there throughout their stay (NICU-NICU group, n=428), admitted to the NICU and then transferred to the Room-In ward (NICU-RIn group, n=1018), or admitted straight to the Room-In ward (RIn only group, n=629). There were no significant differences in the rates of nosocomial infection, bronchopulmonary dysplasia, intraventricular hemorrhage, and retinopathy of prematurity between the NICU-NICU and NICU-RIn groups. The rate of necrotizing enterocolitis was significantly lower in the NICU-RIn group (P=0.04), while weight gain and duration of hospital stay were significantly higher (both Pneonatal care in China.

    Knowledge and skills of heart, head, lung, gut and basic abdominal ultrasound is of immense utility to clinicians in their day-to-day patient management, and in acute events, in the absence of specialist service back-up. This review examines the potential role of clinician-performed ultrasound in the neonatal intensive care unit. The bibliographic search of English-language literature was performed electronically using PubMed and EMBASE databases for the different topics we have covered under this review. Bedside head ultrasound can be used to identify and screen for intraventricular hemorrhage, periventricular leukomalacia and post-hemorrhagic ventricular dilatation. It is also a useful adjuvant tool in the evaluation of hypoxic ischemic encephalopathy. The relatively new lung ultrasound technique is useful in identifying transient tachypnea, pneumonia, pneumothorax, fluid overload and pleural effusion. Gut ultrasound is useful in identifying necrotizing enterocolitis and probably is better than X-ray in prognostication. Ultrasound is also useful in identifying vascular line positions without radiation exposure. Ultrasound performed by the clinician has an extensive role in the neonatal intensive care unit. Basic ultrasound knowledge of head, lung and gut is a useful supplement to clinical decision-making.

    Necrotizing fasciitis is a rare and severe infection characterised by extremely rapid progressive involvement of the superficial fascias and deep dermal layers of the skin, with resultant vasculitis and necrosis. The authors present three clinical cases of necrotizing fasciitis; all three patients previously had varicella rash, rapid progressive spreading erythema with severe pain and toxic shock syndrome. Two patients had positive cultures of b-haemolytic streptococcus. Early stage differential diagnosis with celulitis, aggressive antibiotic treatment and pediatric intensive care support are essential. However, the main therapy is early extensive surgical approach involving all indurate areas, down to and including the muscle fascia.

    This Lebanese study tested the hypothesis that differences would exist in the gut microbiota of preterm infants with and without necrotising enterocolitis (NEC), as reported in Western countries. This study compared 11 infants with NEC and 11 controls, all born at 27-35 weeks, in three neonatal intensive care units between January 2013 and March 2015. Faecal samples were collected at key time points, and microbiota was analysed by culture, quantitative PCR (qPCR) and temperature temporal gel electrophoresis (TTGE). The cultures revealed that all preterm infants were poorly colonised and harboured no more than seven species. Prior to NEC diagnosis, significant differences were observed by qPCR with a higher colonisation by staphylococci (p = 0.034) and lower colonisations by enterococci (p = 0.039) and lactobacilli (p = 0.048) in the NEC group compared to the healthy controls. Throughout the study, virtually all of the infants were colonised by Enterobacteriaceae at high levels. TTGE analysis revealed no particular clusterisation, showing high interindividual variability. The NEC infants were poorly colonised with no more than seven species, and the controls had a more diversified and balanced gut microbiota. Understanding NEC aetiology better could lead to more effective prophylactic interventions and a reduced incidence. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Zinc is a key element for growth and development. In this narrative review, we focus on the role of dietary zinc in early life (including embryo, fetus and preterm neonate), analyzing consequences of zinc deficiency and adequacy of current recommendations on dietary zinc. We performed a systematic search of articles on the role of zinc in early life. We selected and analyzed 81 studies. Results of this analysis showed that preservation of zinc balance is of critical importance for the avoidance of possible consequences of low zinc levels on pre- and post-natal life. Insufficient quantities of zinc during embryogenesis may influence the final phenotype of all organs. Maternal zinc restriction during pregnancy influences fetal growth, while adequate zinc supplementation during pregnancy may result in a reduction of the risk of preterm birth. Preterm neonates are at particular risk to develop zinc deficiency due to a combination of different factors: (i) low body stores due to reduced time for placental transfer of zinc; (ii) increased endogenous losses; and (iii) marginal intake. Early diagnosis of zinc deficiency, through the measurement of serum zinc concentrations, may be essential to avoid severe prenatal and postnatal consequences in these patients. Typical clinical manifestations of zinc deficiency are growth impairment and dermatitis. Increasing data suggest that moderate zinc deficiency may have significant subclinical effects, increasing the risk of several complications typical of preterm neonates (i.e., necrotizing enterocolitis, chronic lung disease, and retinopathy), and that current recommended intakes should be revised to meet zinc requirements of extremely preterm neonates. Future studies evaluating the adequacy of current recommendations are advocated. PMID:26690476

A neonatal composite outcome included: neonatal death, RDS, grades III or IV intraventricular hemorrhage (IVH), sepsis, necrotizing enterocolitis (NEC), or retinopathy of prematurity.  Of 9,867 women, 10.4% ( N  = 1,038) were PTBs; 32.7% ( n  = 340) IPTBs and 67.3% ( n  = 698) SPTBs. Compared with SPTB, the composite maternal outcome was more frequent in IPTB-4.4% versus 0.9% (adjusted odds ratio [aOR], 4.0; 95% confidence interval [CI], 1.4-11.8), as were blood transfusion and prolonged hospital stay (3.2 and 3.7 times, respectively). The frequency of composite neonatal outcome was higher in IPTBs (aOR, 1.8; 95% CI, 1.1-3.0), as were RDS (1.7 times), small for gestational age (SGA) < 5th percentile (7.9 times), and neonatal intensive care unit (NICU) admission (1.8 times).  Adverse maternal and neonatal outcomes were significantly more likely with IPTB than with SPTB.

    Full Text Available We aim to determine risk factors and clinical outcomes for bowel perforation in premature infants with NEC. We analyzed clinical data of 57 cases of premature infants with NEC at our NICU between January 2010 and December 2012. Based on the presence of bowel perforation, we divided these infants into two groups: perforated NEC group (n=10 and nonperforated NEC group (n=47. We compared general information, clinical characteristics, and laboratory findings between groups. The perforated NEC group, compared to the nonperforated NEC group, had significantly lesser gestational age, lower birth weight, higher prevalence of apnea, mechanical ventilation, sepsis and shock, lower blood pH, higher levels of blood glucose, abnormal WBC count and thrombocytopenia, and elevated CRP (all P<0.05. Moreover, the perforated NEC group had significantly longer durations of fasting and TPN usage, higher incidences of EUGR and cholestasis, longer duration of antibiotics, higher frequency of advanced antibiotics use, and poorer prognosis than the nonperforated NEC group (all P<0.05. Bowel perforation in premature infants with NEC was associated with multiple risk factors. Early identification of some of these risk factors in premature infants with NEC may help implement early intervention to reduce the incidence of bowel perforation and thereby improve the prognosis.

    Full Text Available Acute kidney injury (AKI is a complex disorder with clinical manifestations ranging from mild dysfunction to complete kidney failure. The published literature on the incidence and outcome of AKI in the critically ill neonatal population is scarce. The aim of this study was to evaluate the types, the associated risk factors and short-term outcome of AKI in the critically ill neonates. A cohort study was conducted including 100 critically ill neonates successively admitted to the Neonatal Intensive Care Unit. The inclusion criteria were a gestational age ≥28 weeks and body weight ≥1 kg. Exclusion criteria included those with multiple congenital anomalies or on drugs altering glomerular filtration rate or AKI developing postoperatively. Neonates were evaluated for the development of AKI [creatinine >1.5 mg/dL and/or blood urea nitrogen (BUN >20 mg/dL] and were assigned as group A (who developed AKI and group B (who did not develop AKI. Forty-one patients developed AKI (group A among whom nine (22% showed oliguric AKI. The most common risk factors among group A patients were sepsis (75.6% and nephrotoxic drug administration (75.6%, followed by shock (39%. There were no statistically significant differences between both groups except for male sex predominance and necrotizing enterocolitis (NEC, which were significantly higher among group A (P <0.05. Use of continuous positive airway pressure (CPAP ventilation was significantly higher in neonates without AKI (13.6% vs 0.0%, P = 0.02. The mortality rate among group A reached 51.2%. Various risk factors including gender, gestational age, birth weight, shock, NEC, sepsis, nephrotoxic drugs, oliguria and mechanical ventilation were studied as regards outcome of group A, and all factors except gender and oliguria proved to be significantly higher in deceased neonates. Male sex and NEC were important risk factors for developing AKI that was predominantly non-oliguric. CPAP ventilation may have a

    The objective of this study was to determine the mortality rate in patients presenting with Necrotizing Fasciitis. This prospective study was conducted at ward 26, JPMC Karachi over a period of two years from March 2001 to Feb 2003. All patients above the age of 12 years diagnosed to be having Necrotizing Fasciitis and admitted through the Accident and emergency department were included in this study. After resuscitation, the patients underwent the emergency exploration and aggressive surgical debridement. Post-operatively, the patients were managed in isolated section of the ward. The patients requiring grafting were referred to plastic surgery unit. The patients were followed up in outpatients department for about two years. Over all, 25 male and 5 female patients fulfilled the inclusion criteria and were included in this study. The common clinical manifestations include redness, swelling, discharging abscess, pain, fever, skin necrosis and foul smelling discharge etc. The most common predisposing factor was Diabetes mellitus whereas the most commonly involved site was perineum. All patients underwent aggressive and extensive surgical debridements. The common additional procedures included Skin grafting, Secondary suturing, Cystostomy and Orchidectomy. Bacteroides and E. coli were the main micro-organisms isolated in this study. Bacteroides was the most common microorganism isolated among the eight patients who died. Necrotizing Fasciitis is a potentially life threatening emergency condition and carries the mortality rate of about 26.6%. The major contributing factors to increase the mortality missed initially diagnosed, old age, diabetes mellitus truncal involvement and late presentation. Anorectal involvement of disease carry worse prognosis. Hyperbaric oxygen therapy and proper use of unprocessed honey reduced the mortality rate. (author)

    Necrotizing fasciitis belongs to a group of complicated soft tissue infections that can be even life threatening. Despite growing knowledge about its etiology, predictors, and the clinical progression, the mortality remains at a high level with 20%. A relevant reduction can be achieved only by an early diagnosis followed by consistent therapy. The clinical findings in about 75% of the cases are pain out of proportion, edema and tenderness, blisters, and erythema. It is elementary to differentiate a necrotizing or a non-necrotizing soft tissue infection early. In uncertain cases it can be necessary to perform a surgical exploration to confirm the diagnosis. The histopathologic characteristics are the fascial necrosis, vasculitis, thrombosis of perforating veins, the presence of the disease-causing bacteria as well as inflammatory cells like macrophages and polymorphonuclear granulocytes. Secondly, both the cutis and the muscle can be affected. In many cases there is a disproportion of the degree of local and systemic symptoms. Depending on the infectious agents there are two main types: type I is a polymicrobial infection and type II is a more invasive, serious, and fulminant monomicrobial infection mostly caused by group A Streptococcus pyogenes.Invasive, severe forms of streptococcal infections seem to occur more often in recent years. Multimodal and interdisciplinary therapy should be based on radical surgical débridement, systemic antibiotic therapy as well as enhanced intensive care therapy, which is sometimes combined with immunoglobulins (in streptococcal or staphylococcal infections) or hyperbaric oxygen therapy (HBOT, in clostridial infections). For wound care of extensive soft tissue defects vacuum-assisted closure has shown its benefit.

    Necrotizing pneumonia causes necrosis of pulmonary parenchyma and may lead to pulmonary gangrene. Prior to the antibiotic era, extensive pulmonary involvement was potentially fatal, but the incidence of necrotizing pneumoniais now less common. On contrast-enhanced CT scans, consolidation with contrast enhancement containing necrotic foci with low attenuation and cavities is characteristic. Radiologic findings do not differ according to the causative organism and in most of cases, specific diagnosis may be impossible. Clinical findings and certain characteristic radiologic findings may be helpful for narrowing the differential diagnosis. We illustrate the clinical and radiologic characteristics of necrotizing pneumonia according to causative bacterial organisms

    Background:Denying parents access to their infant in the Neonatal Intensive Care Unit (NICU) is a standard practice in most hospitals across China.Visitation is not usually permitted or may be strictly limited,and NICU care for most neonates is provided by health-care professionals with little participation of the parents.An exception to this rule is the level 2 "Room-In" ward in Qilu Children's Hospital,Shandong University,where parents have 24-hour access to their infants and participate in providing care.Methods:This retrospective cohort study compared the outcomes of infants who were admitted to the NICU and remained there throughout their stay (NICU-NICU group,n=428),admitted to the NICU and then transferred to the Room-In ward (NICU-RIn group,n=1018),or admitted straight to the Room-In ward (RIn only group,n=629).Results:There were no significant differences in the rates of nosocomial infection,bronchopulmonary dysplasia,intraventricular hemorrhage,and retinopathy of prematurity between the NICU-NICU and NICURIn groups.The rate of necrotizing enterocolitis was significantly lower in the NICU-RIn group (P=0.04),while weight gain and duration of hospital stay were significantly higher (both P<0.001).Rates of adverse outcomes were lower in RIn-only infants due to their low severity of illness on admission.Conclusions:Allowing parents access to their infant in the NICU is feasible and safe in China,and may result in improvements in infant outcomes.Further studies are required to generate stronger evidence that can inform changes to neonatal care in China.

    Objective  This retrospective cohort study examined the effect of birth order on neonatal morbidity and mortality in very preterm twins. Study Design  Using 2005 to 2012 data from the Canadian Neonatal Network, very preterm twins born between 24 0/7 and 32 6/7 weeks of gestation were included. Odds of morbidity and mortality of second-born cotwins compared with first-born cotwins were examined by matched-pair analysis. Outcomes were neonatal death, severe brain injury (intraventricular hemorrhage grade 3 or 4 or persistent periventricular echogenicity), bronchopulmonary dysplasia, severe retinopathy of prematurity (ROP) (> stage 2), necrotizing enterocolitis (≥ stage 2), and respiratory distress syndrome (RDS). Multivariable analysis was performed adjusting for confounders. Result  There were 6,636 twins (3,318 pairs) included with a mean gestational age (GA) of 28.9 weeks. A higher rate of small for GA occurred in second-born twins (10 vs. 6%). Mortality was significantly lower for second-born twins (4.3 vs. 5.3%; adjusted odds ratio: 0.75; 95% confidence interval [CI]: 0.59-0.95). RDS (66 vs. 60%; adjusted odds ratio: 1.40; 95% CI: 1.29-1.52) and severe retinopathy (9 vs. 7%; adjusted odds ratio: 1.46; 95% CI: 1.07-2.01) were significantly higher in second-born twins. Conclusion  Thus, while second-born twins had reduced odds of mortality, they also had increased odds of RDS and ROP. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Five patients with radiation enterocolitis who were surgically treated are reported. The 5 patients had received irradiation therapy more than 5,000 rad for ginecologic malignancies. The period for the onset of symptoms of irradiation enteritis ranged from 8 months to 20 years however, 3 of them developed the symptoms within one year after irradiation therapy. Emergency surgery was carried out for bowel obstruction in 3 cases and for intestinal perforation in 2 cases. Bowel resection and primary anastomosis were performed by a one-step approach in 4 of them. Transient colostomy as preventive measure was added in 2 cases. It is very important for the one-step approach to resect the intestine at the healthy part far from the lesion of irradiation enteritis and to add a transient colostomy to prevent anastomolic insufficiency. Furthermore, suture material should be used less tissue reactive one. (author).

    Full Text Available Foodborne diseases caused by Salmonella enterica serovar Enteritidis (S. Enteritidis are a significant health problem. Pregnancy, state of immunological tolerance, is a predisposing condition for the development of infections with intracellular pathogens. Salmonella species can cause pregnancy complications such as chorioamnionitis, transplacental fetal infection, pre term labor, abortions, neonatal and maternal septicemia. However, the specific mechanisms by which Salmonella infections trigger these alterations are not clear. In the present work, using a self-limiting enterocolitis murine model, we show that the ingestion of a low dose of S. Enteritidis at late stages of pregnancy (day 15 of gestation is sufficient to induce massive maternal infection. We found that Salmonella infection leads to 40% of pre term delivery, 33% of abortion and fetal growth restriction. Placental dysfunction during S. Enteritidis enterocolitis was confirmed through cellular infiltration and hypoxia markers (MPO activity and COX-1 and COX-2 expression, respectively. Apoptosis in placental tissue due to Salmonella infection was also evident at day 18 of gestation when investigated by morphometric procedure, DNA fragmentation and Fas/FasL expression. Also, the expression of IFN-γ, TNF-α, IL-17 and IL-10 was up regulated in response to Salmonella not only in placenta, but also in amniotic fluid and maternal serum. Altogether, our results demonstrate that S. Enteritidis enterocolitis during late stages of gestation causes detrimental effect on pregnancy outcome.

    Full Text Available BACKGROUND: Obstetric decision- making for the growth restricted foetus has to take into consideration the benefits and risks of waiting for pulmonary maturity and continued exposure to hostile intra-uterine environment. Necrotising Enterocolitis (NEC results from continued exposure to hostile environment and is an important cause of poor neonatal outcome. AIMS: To evaluate the predictive value of abnormal Doppler flow velocimetry of the foetal umbilical artery for NEC and neonatal mortality. SETTINGS AND DESIGN: A retrospective study carried out at a tertiary care centre for obstetric and neonatal care. MATERIALS AND METHOD: Seventy-seven neonates with birth weight less than 2000 gm, born over a period of 18 months were studied. These pregnancies were identified as having growth abnormalities of the foetus. Besides other tests of foetal well-being, they were also subjected to Doppler flow velocimetry of the foeto-placental vasculature. Obstetric outcome was evaluated with reference to period of gestation and route of delivery. The neonatal outcome was reviewed with reference to birth weight, Apgar scores and evidence of NEC. STATISTICAL ANALYSIS USED: Chi square test. RESULTS: In the group of patients with Absent or Reverse End Diastolic Frequencies (A/R EDF in the umbilical arteries, positive predictive value for NEC was 52.6%, (RR 30.2; OR 264. The mortality from NEC was 50%. When umbilical artery velocimetry did not show A/REDF, there were no cases of NEC or mortality. Abnormal umbilical or uterine artery flow increased the rate of caesarean section to 62.5% as compared to 17.6% in cases where umbilical artery flow was normal. CONCLUSION: In antenatally identified pregnancies at risk for foetal growth restriction, abnormal Doppler velocimetry in the form of A/REDF in the umbilical arteries is a useful guide to predict NEC and mortality in the early neonatal period.

    In this study, we investigated the relationship of mean platelet volume (MPV) with the presence and the severity of intrauterine growth restriction (IUGR) and with neonatal complications. The pregnancies with and without IUGR, that were followed-up in our hospital between 2003 and 2009 were analyzed retrospectively. Pregnancies which resulted in birth of a newborn with a birthweight less than 10th percentile for the gestational age were selected for IUGR group. IUGR cases were divided into three groups according to the Doppler parameters. There was no significant difference between the MPV values in the groups. There was no association between MPV and Doppler parameters that can be used in predicting the severity of IUGR. There was no significant relation between MPV and the perinatal complications such as intracranial hemorrhage (ICH), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), the development of sepsis, postpartum exitus (PPEX) and intrauterine exitus (IUEX). Higher MPV values were associated with hospitalization in the neonatal intensive care unit (NICU) and respiratory distress syndrome (RDS) in the IUGR group. Analysis of MPV is a simple and readily available laboratory test. Prospective researches employing standard measurement technics are required to clarify the relationship between MPV and IUGR.

    We assessed central-peripheral temperature gradient alteration for the diagnosis of late-onset neonatal sepsis and compared earliness detection of this sign with altered blood cell count and C-reactive protein. Thirty-one preterm babies (peripheral) temperatures were continuously monitored with a thermal probe (ThermoTracer; Dräger Medical AGF & Co. KgaA, Lübeck, Germany) adjusting incubator air temperature for a thermal gradient peripheral temperature alteration was defined as a thermal gradient >2°C that could not be corrected with protocolized air temperature modifications. Proven (positive blood culture) sepsis and probable late-onset sepsis were recorded. Late-onset sepsis was diagnosed in 11 neonates (proven, 9; probable, 2). Thermal gradient alteration was present in 12 cases, in association with the onset of sepsis in 10 and concomitantly with a ductus arteriosus and stage 1 necrotizing enterocolitis in 2. Thermal gradient alteration had a sensitivity of 90.9% [95% confidence interval (CI), 62.3-98.4] and specificity of 90% (95% CI, 69.9-97.2%), and in 80% of cases, it occurred before abnormal laboratory findings. Central-peripheral temperature gradient monitoring is a feasible, non-invasive, and simple tool easily applicable in daily practice. An increase of >2°C showed a high-sensitivity and specificity for the diagnosis of late-onset sepsis.

    Human milk feeding protects against oxidative stress-induced damage in preterm neonates, including severe multifactorial diseases such as retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC), and bronchopulmonary dysplasia (BPD). The carotenoids, which are not found in formula milk, might play a key role in these actions. A multicenter, double-blind, randomized controlled trial was conducted in three tertiary Italian neonatal intensive care units. All preterm infants lutein + 0.0006 mg zeaxanthin) or placebo (5% glucose solution) from birth till 36 weeks' corrected gestational age. Primary outcomes were threshold ROP, NEC > second stage, and BPD. Surveillance for detection of these diseases and for intolerance/adverse effects was performed. No treatment-related adverse effect was documented in the 229 analyzed infants, whose clinical/demographical characteristics were similar in the two groups. Threshold ROP incidence did not significantly differ in treated (6.2%) versus not treated infants (10.3%; p = 0.18). The same occurred for NEC (1.7% versus 5.1%; p = 0.15) and BPD (4.5% versus 10.3%; p = 0.07). Noteworthy, the progression rate from early ROP stages to threshold ROP was decreased by 50% (0.30 versus 0.44; p = 0.23). Lutein/zeaxanthin supplementation in preterm infants is well tolerated. No significant effect was seen on threshold ROP, NEC, or BPD. The decreasing trends of these outcomes in the treatment group need to be assessed and confirmed on larger sample-sizes.

    During the past 12 years, delayed radiation enterocolitis developed in 22 patients treated for uterine cervical cancer or endometrial cancer. Their ages ranged from 36 to 77 years with an average age of 62. Ten patients received external irradiation and the other 12 patients received the combined external and internal irradiation. Radiation doses were 50 Gy-156 Gy with an average dose of 80 Gy. All patients had early radiation effects manifested by myxoid bloody stool (82%), diarrhea (46%), defecation disorder (18%), and tenesmus like symptoms (9%). These symptoms resolved within one month after irradiation. The most common symptom for delayed radiation effects was anal hemorrhage and melena (73%), followed by ileus like symptoms and abdominal pain (14%). Defecation disorder, diarrhea, and anemia were observed in one each patient (5%). Latency period ranged from 4 months to 13 years after radiation treatment, with the greatest number (86%) having it within one year and 3 months. There was no definitive correlation between radiation doses and latency period. Histopathological features included marked proliferation extending from the submucosal layer to the muscular layer, endometrial thickening of the small vessels, and thrombopoiesis. Although surgical treatment was performed in 20 patients, favorable outcome was not achieved. (N.K.).

    ultrasonograms (73%), 775 had periventricular-intraventricular hemorrhage (18.5%), and 73 had cystic periventricular leukomalacia (1.7%). Outcomes were available for 3008 of 3345 neonates with ventriculomegaly or normal scans (90%). Compared with normal cranial ultrasonograms, ventriculomegaly was associated with lower gestational age, male sex, and bronchopulmonary dysplasia, late-onset sepsis, meningitis, necrotizing enterocolitis, and stage 3 retinopathy of prematurity. After adjustment, neonates with ventriculomegaly had higher odds of neurodevelopmental impairment (odds ratio [OR], 3.07; 95% CI, 2.13-4.43), cognitive impairment (OR, 3.23; 95% CI, 2.09-4.99), moderate/severe cerebral palsy (OR, 3.68; 95% CI, 2.08-6.51), death/neurodevelopmental impairment (OR, 2.17; 95% CI, 1.62-2.91), but not death alone (OR, 1.09; 95% CI, 0.76-1.57). Behavioral outcomes did not differ. Nonhemorrhagic ventriculomegaly is associated with increased odds of neurodevelopmental impairment among extremely preterm neonates.

    Blood concentrations of eosinophils and monocytes are part of the complete blood count. Reference ranges for these concentrations during the neonatal period, established by very large sample sizes and modern methods, are needed for identifying abnormally low or high values. We constructed reference ranges for eosinophils per microl and monocytes per microl among neonates of 22 to 42 weeks of gestation, on the day of birth, and also during 28 days after birth. Data were obtained from archived electronic records over an eight and one-half-year period in a multihospital health-care system. In keeping with the reference range concept, values were excluded from neonates with a diagnosis of infection or necrotizing enterocolitis (NEC). Eosinophils and monocytes per microl of blood were electronically retrieved from 96 162 records, of which 63 371 that lacked a diagnosis of infection or NEC were included in this reference range report. The mean value for eosinophils per microl on the day of birth increased linearly between 22 and 42 weeks of gestation, as did the 5 and 95% values. The reference range at 40 weeks was 140 to 1300 microl(-1) (mean 550 microl(-1)). Similarly, the mean value for monocytes increased linearly over this interval, with a reference range at 40 weeks of 300 to 3300 microl(-1) (mean 1400 microl(-1)). Over the first 4 weeks after birth, no appreciable change was observed in 5% limit and mean eosinophil count, with a slight increase in the 95% limit in week 4. A slight increase in monocyte count was observed during the first 2 weeks after birth. The results of this analysis describe reference ranges for blood concentrations of eosinophils and monocytes during the neonatal period. Additional study is needed for determining the relevance of values falling outside the reference range.

    To determine the impact of neighbourhood income and maternal residence population density on mortality and various morbidities at discharge or transfer from the NICU among extremely preterm neonates (<27 weeks gestation) in Canada. Neighbourhood income level and residential status was derived using a postal code conversion file and census data. Multivariable logistic regression analysis was used to estimate the risk-adjusted odds ratio (AOR) of mortality and survival without major morbidities (chronic lung disease, necrotizing enterocolitis, severe intraventricular hemorrhage, and retinopathy of prematurity) among 2,752 extremely preterm infants admitted to 25 tertiary level neonatal intensive care units in Canada between 2007 and 2008. There were no significant differences between mothers from different neighbourhood income quintiles (Q1 = low; Q5 = high) and neonatal mortality AOR (95% confidence interval): Q1: 1.10 (0.74-1.62), Q2: 1.00 (0.67-1.49), Q3: 1.39 (0.93-2.07), Q4: 1.01 (0.67-1.52), Q5: 1 (reference); or survival without major morbidity: Q1: 1.01 (0.70-1.44), Q2: 0.84 (0.58-1.23), Q3: 0.85 (0.58-1.24), Q4: 0.92 (0.63-1.35), Q5: 1 (reference). There were no significant differences in mortality (AOR 1.14 [0.83-1.57]) or in survival without major morbidity (AOR 0.92 [0.67-1.26]) between infants of mothers residing in sparsely populated areas compared to densely populated areas. Maternal residence in a low-income neighbourhood or sparsely populated area was not associated with higher odds of mortality or survival free of major morbidities in extremely preterm infants.

    To determine whether primary peritoneal drainage improves survival and outcome of extremely low birth weight (ELBW) infants with intestinal perforation. Optimal surgical management of ELBW infants with intestinal perforation is unknown. An international multicenter randomized controlled trial was performed between 2002 and 2006. Inclusion criteria were birthweight >or=1000 g and pneumoperitoneum on x-ray (necrotizing enterocolitis or isolated perforation). Patients were randomized to peritoneal drain or laparotomy, minimizing differences in weight, gestation, ventilation, inotropes, platelets, country, and on-site surgical facilities. Patients randomized to drain were allowed to have a delayed laparotomy after at least 12 hours of no clinical improvement. Sixty-nine patients were randomized (35 drain, 34 laparotomy); 1 subsequently withdrew consent. Six-month survival was 18/35 (51.4%) with a drain and 21/33 (63.6%) with laparotomy (P = 0.3; difference 12% 95% CI, -11, 34%). Cox regression analysis showed no significant difference between groups (hazard ratio for primary drain 1.6; P = 0.3; 95% CI, 0.7-3.4). Delayed laparotomy was performed in 26/35 (74%) patients after a median of 2.5 days (range, 0.4-21) and did not improve 6-month survival compared with primary laparotomy (relative risk of mortality 1.4; P = 0.4; 95% CI, 0.6-3.4). Drain was effective as a definitive treatment in only 4/35 (11%) surviving neonates, the rest either had a delayed laparotomy or died. Seventy-four percent of neonates treated with primary peritoneal drainage required delayed laparotomy. There were no significant differences in outcomes between the 2 randomization groups. Primary peritoneal drainage is ineffective as either a temporising measure or definitive treatment. If a drain is inserted, a timely "rescue" laparotomy should be considered.

    An ostomy seems a safe alternative in neonates with an acute abdomen when immediate restoration of bowel continuity is deemed undesirable. Faced with several complications in our center, and the feeling we are not the only center with these complications, we decided to assess the rate and type of complications after both ostomy creation and closure. All data regarding neonates (ostomy take down, and complications and mortality directly related to both creation and closure of the ostomy. A total of 155 patients who underwent a laparotomy for suspect acute abdomen were identified. Median gestational age was 33 weeks (range 25 to 40) and median birth weight was 1926 g (range 560 to 4380). Median age at laparotomy was 8 days (range 0 to 30). Indications for surgery were necrotizing enterocolitis (n = 38), spontaneous intestinal perforation (n = 11), intestinal atresia (n = 9) or obstruction (n = 5), and volvulus (n = 4). An ostomy was created in 67 patients (67/155: 43%): 38 boys and 29 girls. There were 8 jejuno-, 49 ileo-, and 10 colostomies created. In almost all cases (94%), a mucous fistula was also constructed.In 23 patients (23/67: 34%) ostomy-related complications occurred. Most frequent were high output ostomy (n = 10) and necrosis of the enterostomy (n = 7). Due to either one of the complications, nine patients (9/67: 13%) needed a reoperation.In this study, 11 patients died before ostomy closure could occur. In 53 patients, the ostomy was closed after a median of 107 days (range 4 to 299).After ostomy closure, complications occurred in 13 cases (13/53: 25%). Seven patients (7/53: 13%) needed another reoperation because of anastomotic leakage (n = 4), adhesions (n = 2), or incisional hernia (n = 1). There was no closure-related mortality. Although creating a temporary ostomy in newborns is preferable in certain situations, there is a considerable occurrence of complications and reoperations.

    Full Text Available Background: Nosocomial infections are an important cause of mortality in neonatal intensive care units (NICUs. Therefore, in this study, the incidence and prevalence of nosocomial infections were determined in NICUs of the three largest neonatal centers in northwest Iran, and the causative bacteria were identified in order to provide potential solutions to control the infections in these hospitals. Materials and Methods: This is a descriptive-prospective study in which the cases of nosocomial infections were examined in the three largest hospitals in Tabriz in northwest Iran during 1 year (from June 2012 until May 2013 based on clinical findings, medical and nursing reports of patients, and laboratory results. Results: Of the 3129 patients hospitalized in NICUs of the three hospitals, 208 patients were diagnosed with nosocomial infections. The incidence rate of nosocomial infections was 11.34%.per 100 patient days with 52.4% bacteremia, 32.69% pneumonia, 5.77% urinary tract infections, 5.29% wound infections, and 3.85% necrotizing enterocolitis. There was a statistically significant relationship between invasive procedures (such as umbilical catheters, central venous catheters, surgery, and TPN and sepsis (P = 0.001. The relationships between urinary tract infection and urinary catheter (P = 0.000, and aggressive procedures (such as suctioning and intubation and pneumonia (P = 0.001 were also statistically significant. Conclusion: Incidence of nosocomial infections in premature and low birth weight newborns is considered as a health threat. The findings of this research reiterate the importance of giving further attention to prevention and control of nosocomial infections in the NICU.

    To systematically review and meta-analyse the relationship between antibiotic exposure in neonates and the following early adverse outcomes: necrotizing enterocolitis (NEC), invasive fungal infections (IFIs) and/or death. Data sources were PubMed, Embase, Medline and the Cochrane Database (to December 2016), supplemented by manual searches of reference lists. Randomized controlled trials (RCTs) and observational studies were included if they provided data on different categories of antibiotic exposures (yes versus no, long versus short duration, and/or broad- versus narrow-spectrum regimens) and the risk of developing NEC, IFI and/or death in the neonatal period. Two reviewers extracted data and evaluated the risk of bias using the Cochrane Handbook, adapted to include observational studies. When appropriate, meta-analyses were conducted using the random-effect model. We identified 9 RCTs and 38 observational studies. The quality of the majority of studies was poor to moderate. There was a significant association between prolonged antibiotic exposure and an increased risk of NEC in five observational studies (5003 participants) and/or risk of death in five observational studies (13 534 participants). Eleven of 15 studies with data on broad- versus narrow-spectrum regimens reported an increased risk of IFI after broad-spectrum antibiotic exposure, in particular with third-generation cephalosporins and carbapenems. Meta-analysis was limited by few and old RCTs, insufficient sample sizes and diversity of antibiotic exposure and outcomes reported. Prolonged antibiotic exposure in uninfected preterm infants is associated with an increased risk of NEC and/or death, and broad-spectrum antibiotic exposure is associated with an increased risk of IFI. © The Author 2017.

    To evaluate the impact of major neonatal morbidities on the risks for rehospitalization in children and adolescents born of very low birth weight. An observational study was performed on data of the Israel Neonatal Network linked together with the Maccabi Healthcare Services medical records. After discharge from the neonatal intensive care unit, 6385 infants of very low birth weight born from 1995 to 2012 were registered with Maccabi Healthcare Services and formed the study cohort. Multivariable negative binomial regression models were calculated to estimate the adjusted relative risk (aRR) and 95% CI for hospitalization. Up to 18 years following discharge, 3956 infants were hospitalized at least once. The median age of follow-up was 10.7 years with total of follow-up of 67 454 patient years and 10 895 hospitalizations. The risks for rehospitalization were increased significantly for each of the neonatal morbidities: surgical necrotizing enterocolitis (NEC), aRR 2.71 (95% CI 2.08-3.53), intraventricular hemorrhage grades 3-4, 2.13 (1.85-2.46), periventricular leukomalacia (PVL), 1.83 (1.58-2.13), bronchopulmonary dysplasia, 1.94 (1.72-2.17), and retinopathy of prematurity stages 3-4, 1.59 (1.36-1.85). During the first 4 years, children with surgically treated NEC, intraventricular hemorrhage, PVL, or bronchopulmonary dysplasia had 1.5- to 2.5-fold greater risks for hospitalization compared with those without the specific morbidity. In the 11th-14th and 15th-18th years, respectively, surgically treated NEC was associated with a 3.05 (1.32-7.04) and 3.26 (0.99-10.7) aRR for hospitalization, and PVL was associated with a 2.67 (1.79-3.97) and 3.47 (2.03-5.92) aRR for hospitalization. Specific major neonatal morbidities as well as the number of morbidities were associated with excess risks of rehospitalization through childhood and adolescence. Copyright © 2017 Elsevier Inc.

    Full Text Available Introduction. Necrotizing fasciitis is an uncommon condition in general practice but one that provokes serious morbidity. It is characterized by widespread fascial necrosis with relative sparing of skin and underlying muscle. Herein, we report a fatal case of necrotizing fasciitis in a young healthy woman after episiotomy. Case Report. A 17-year-old primigravida underwent a vaginal delivery with mediolateral episiotomy. Necrotizing fasciitis was diagnosed on the 5th postpartum day, when the patient was referred to our tertiary care medical center. Surgical debridement was initiated together with antibiotics and followed by hyperbaric oxygen therapy. The patient died due to septic shock after 16 hours from the referral. Conclusion. Delay of diagnosis and consequently the surgical debridement were most likely the reasons for maternal death. In puerperal period, a physician must consider necrotizing fasciitis as a possible diagnosis in any local sings of infection especially when accompanied by fever and/or tenderness. Early diagnosis is the key for low mortality and morbidity.

    A 74-year-old woman presented with bowel movement disorder. She had received radiation therapy with 60 Gy for uterine cervical cancer approximately 20 years before. Barium enema and colonofiberscopy revealed radiation enterocolitis. Thereafter, the patient was admitted to the hospital due to stricture of the sigmoid colon and an increased CEA and was diagnosed as having Borrmann II type colorectal well differentiated adenocarcinoma. Histological examination revealed stage I with no associated lymph node metastases. She is alive 3 years and 10 month after surgery. The other patient was a 65 year-old woman with a history of cervical cancer. Twenty-one years after combined hysterectomy and postoperative external irradiation of 45 Gy, the patient presented with melena. Detailed examination revealed colorectal adenocarcinoma. Simultaneously, barium enema revealed radiation enterocolitis. At surgery, intrapelvic area was found to be frozen due to irradiation. She has no evidence of metastasis 2 years after surgery. As can be shown in the two patients, patients developing radiation enterocolitis should be followed up periodically for the early detection of coexistent colorectal cancer. (N.K.)

    Necrotizing fasciitis (NF) is a rare, life-threatening soft-tissue infection and a medical and surgical emergency, with increasing incidence in the last few years. It is characterized by a rapidly spreading, progressive necrosis of the deep fascia and subcutaneous tissue. Necrotizing fasciitis is often underestimated because of the lack of specific clinical findings in the initial stages of the disease. Many adjuncts such as laboratory findings, bedside tests - e.g., the ''finger test'' or biopsy - and imaging tests have been described as being helpful in the early recognition of the disease. Imaging is very useful to confirm the diagnosis, but also to assess the extent of the disorder, the potential surgical planning, and the detection of underlying etiologies. The presence of gas within the necrotized fasciae is characteristic, but may be lacking. The main finding is thickening of the deep fasciae due to fluid accumulation and reactive hyperemia, best seen on magnetic resonance imaging. (orig.)

  6. Development of the preterm gut microbiome in twins at risk of necrotising enterocolitis and sepsis.

    Full Text Available The preterm gut microbiome is a complex dynamic community influenced by genetic and environmental factors and is implicated in the pathogenesis of necrotising enterocolitis (NEC and sepsis. We aimed to explore the longitudinal development of the gut microbiome in preterm twins to determine how shared environmental and genetic factors may influence temporal changes and compared this to the expressed breast milk (EBM microbiome. Stool samples (n = 173 from 27 infants (12 twin pairs and 1 triplet set and EBM (n = 18 from 4 mothers were collected longitudinally. All samples underwent PCR-DGGE (denaturing gradient gel electrophoresis analysis and a selected subset underwent 454 pyrosequencing. Stool and EBM shared a core microbiome dominated by Enterobacteriaceae, Enterococcaceae, and Staphylococcaceae. The gut microbiome showed greater similarity between siblings compared to unrelated individuals. Pyrosequencing revealed a reduction in diversity and increasing dominance of Escherichia sp. preceding NEC that was not observed in the healthy twin. Antibiotic treatment had a substantial effect on the gut microbiome, reducing Escherichia sp. and increasing other Enterobacteriaceae. This study demonstrates related preterm twins share similar gut microbiome development, even within the complex environment of neonatal intensive care. This is likely a result of shared genetic and immunomodulatory factors as well as exposure to the same maternal microbiome during birth, skin contact and exposure to EBM. Environmental factors including antibiotic exposure and feeding are additional significant determinants of community structure, regardless of host genetics.

    Full Text Available Background. In recent decades, medical community has increasingly been calling attention to the importance of Campylobacter as an disease-causing agent in humans. Nowdays, Campylobacter jejuni (C. jejuni is known as the most frequent bacterial cause of diarrhea worldwide. Epidemiological differences of the infections caused by Campylobacter, present in the developed and the developing countries, are attributed to the differences of the types of virulence. Due to the specificity, and the demanding features of Campylobacter, as well as poorly equipped microbiological laboratories, campylobacteriosis is insufficiently studied in our country. This investigation aimed to determine the participation of some Campylobacter species in the etiology of diarrheal diseases in our population. Methods. The four-years continuous monitoring of Campylobacter presence was performed in the faeces of 12 605 patients with enterocolitis. The control group included 5 774 examinees of healthy children and youth. Faeces samples were cultivated on Skirrow's selective medium, and further incubated according to effective methodology for Campylobacter. Identification of strains was based on morphological, cultural and physiologic features of strains (oxidase test, catalase test, susceptibility to nalidixic acid, and hypurate hydrolysis. As a statistical method, for data processing, c2 test and Fisher’s exact test were used. Results. Campylobacter was proven in 3.86% of enterocolitis patients, and in 0.71% of healthy population. Out of 518 Campylobacter isolates, 86.48% belonged to enterocolitis outpatients, and 13,51% to inpatients. Predominant symptoms of the disease were diarrhea (81.83%, increased temperature (34.71%, vomiting (19.77%, and stomach pain (15.17%. The diseased were predominantly infants in the first year of life. Out of 300 Campylobacter isolates, 75% were identified as Campylobacer jejuni, 23% as Campylobacter coli (C. coli, and 2% as Campylobacter lari

    Full Text Available Background: Although the mortality rate for preterm infants and the gestational age-specific mortality rate have dramatically improved over the last 3 to 4 decades, infants born preterm remain vulnerable to many complications, including respiratory distress syndrome, chronic lung disease, necrotizing enterocolitis, a compromised immune system, cardiovascular disorders, hearing and vision problems, and brain lesions.The aim is to determine mortality and morbidity rates and selected outcome variables for preterm infant’s < 30 weeks’ gestation, who were admitted to the NICU. Patients and methods: This study enrolled 102 infants with gestational age less than 30 weeks’ gestation, hospitalized in Neonatal Intensive Care Unit, Pediatric Hospital, Clinical University Center Sarajevo, from Jan. 2010 to Dec. 2010. Parameters taken at admission were: birth weight, gestational age, Apgar score, excess base and CRIB score. Early outcome is considered as a survival at discharge or common preterm morbidities presented during hospitalizationResults: The mean BW of evaluated preterm infants was 1086 ± 250 g, the mean GA27.89 ± 1.97, Apgar score 5.41 ± 1.76, excess base at admission 6.39 ± 1.74 and mean CRIB score 3.72 ± 3.16. The overall survival rate was 70.5%. Selected outcomes at discharge were: RDS with 70.5% infants treated with natural surfactant, PDA treated with NSAIDS (23.5%, brain injury ( ≥ grade 3 IVH or PVL 16.6%, NEC Bell stages II or III 9.8%, BPD 25/72 (33.3% of infants who survived to 36 weeks postmenstrual age.

    Full Text Available Necrotizing fasciitis is a life-threatening soft tissue infection that results in rapid local tissue destruction. Type 1 necrotizing fasciitis is characterized by polymicrobial, synergistic infections that are caused by non-Group A streptococci, aerobic and anaerobic organisms. Type 2 necrotizing fasciitis involves Group A Streptococcus (GAS with or without a coexisting staphylococcal infection. Here we provide the first report of necrotizing fasciitis jointly associated with the microbes Group B Streptococcus and Staphylococcus lugdunensis. S. lugdunensis is a commensal human skin bacterium known to cause often painful and prolonged skin and soft tissue infections. To our knowledge, however, this is the first case of Staph. lugdunensis-associated necrotizing fasciitis to be reported in the literature.

    Campylobacter spp. are a common cause of mostly self-limiting enterocolitis. Although rare, pericarditis and myopericarditis have been increasingly documented as complications following campylobacteriosis. Such cases have occurred predominantly in younger males, and involved a single causative species, namely Campylobacter jejuni. We report the first case of myopericarditis following Campylobacter coli enterocolitis, with illness occurring in an immunocompetent middle-aged female. A 51-yo female was admitted to a cardiology unit with a 3-days history of chest pain. The woman had no significant medical history or risk factors for cardiac disease, nor did she report any recent overseas travel. Four days prior to the commencement of chest pain the woman had reported onset of an acute gastrointestinal illness, passing 3-4 loose stools daily, a situation that persisted at the time of presentation. Physical examination showed the woman's vital signs to be essentially stable, although she was noted to be mildly tachycardic. Laboratory testing showed mildly elevated C-reactive protein and a raised troponin I in the absence of elevation of the serum creatinine kinase. Electrocardiography (ECG) demonstrated concave ST segment elevations, and PR elevation in aVR and depression in lead II. Transthoracic echocardiogram (TTE) revealed normal biventricular size and function with no significant valvular abnormalities. There were no left ventricular regional wall motion abnormalities. No pericardial effusion was present but the pericardium appeared echodense. A diagnosis of myopericarditis was made on the basis of chest pain, typical ECG changes and troponin rise. The chest pain resolved and she was discharged from hospital after 2-days of observation, but with ongoing diarrhoea. Following discharge, a faecal sample taken during the admission, cultured Campylobacter spp. Matrix assisted laser desorption ionization time-of-flight (Bruker) confirmed the cultured isolate as C. coli

    Full Text Available CONTEXT: Although the benefits of antenatal corticosteroids have been widely demonstrated in other countries, there are few studies among Brazilian newborn infants. OBJECTIVE: To evaluate the effectiveness of antenatal corticosteroids on the incidence of respiratory distress syndrome and intra-hospital mortality among neonates with a gestational age of less than 34 weeks. TYPE OF STUDY: Cross-sectional. SETTING: A tertiary-care hospital. PARTICIPANTS: Neonates exposed to any dose of antenatal corticosteroids for fetal maturation up to 7 days before delivery, and newborns paired by sex, birth weight, gestational age and time of birth that were not exposed to antenatal corticosteroids. The sample obtained consisted of 205 exposed newborns, 205 non-exposed and 39 newborns exposed to antenatal corticosteroids for whom it was not possible to find an unexposed pair. PROCEDURES: Analysis of maternal and newborn records. MAIN MEASUREMENTS: The primary clinical outcomes for the two groups were compared: the incidence of respiratory distress syndrome and intra-hospital mortality; as well as secondary outcomes related to neonatal morbidity. RESULTS: Antenatal corticosteroids reduced the occurrence of respiratory distress syndrome (OR: 0.33; 95% CI: 0.21-0.51 and the protective effect persisted when adjusted for weight, gestational age and the presence of asphyxia (adjusted OR: 0.27; 95% CI: 0.17-0.43. The protective effect could also be detected through the reduction in the need for and number of doses of exogenous surfactant utilized and the number of days of mechanical ventilation needed for the newborns exposed to antenatal corticosteroids. Their use also reduced the occurrence of intra-hospital deaths (OR: 0.51: 95% CI: 0.38-0.82. However, when adjusted for weight, gestational age, presence of prenatal asphyxia, respiratory distress syndrome, necrotizing enterocolitis and use of mechanical ventilation, the antenatal corticosteroids did not maintain the

A secondary composite of serious neonatal morbidity also was defined prospectively. The study included 1089 mother/baby pairs. Composite morbidity between those with premature labor (77.2%) and premature rupture of membranes (73.2%) was not significantly different (P = .29). A few neonatal complications were associated with indications for admission and delivery, but on logistic regression adjusting for gestational age and other confounders, suspected intrauterine growth restriction was the only indication for admission or delivery associated with an increase in serious morbidity (odds ratio 4.5, [2.1 to 9.8], P neonatal outcome. In this study evaluating all of the most frequent indications, however, we found only suspected intrauterine growth restriction as an indication for admission and delivery was found to be so. Thus, it seems that in almost all situations counseling patients can be based primarily on gestational age along with other factors including estimated fetal weight, sex, race, plurality, and completion of a course of antenatal corticosteroids.

    2012-03-01

    Enterocolic lymphocytic phlebitis (ELP) is a rare disease of unknown etiology involving most often the intramural and mesenteric small and medium-sized veins of the gastrointestinal tract. The diagnosis of the disorder is based on the histopathological examination of a surgical specimen as endoscopically obtained diagnostic material is usually too superficial. Clinical manifestation of ELP most frequently is characterized by acute symptoms, such as acute abdomen, signs suggesting acute appendicitis, gastrointestinal hemorrhage, sometimes it manifests as chronic gastrointestinal complaints. We report, to our knowledge for the first time in Poland, a case of ELP with clinical symptoms pointing to acute appendicitis, on laparoscopy manifesting as a tumorous mass in the colonic wall with an unchanged appendix.

Periventricular leukomalacia was diagnosed by persistent diffuse periventricular hyperechogenecity for more than 7 days, or by periventricular cysts. The VLBWI were separated into two groups on the basis of the presence or absence of PVL. Sepsis was defined as clinical manifestation plus a positive culture. The Mann-Whitney, chi-square and t tests were applied followed by logistic regression. RESULTS: A total of 88 VLBWI were studied. Of these, 62 (70.5% survived and 51 (57.8% had PVL. Both groups were similar in terms of birth weight, gestational age, Apgar score, type of delivery, SNAPPE-II score, presence of necrotizing enterocolitis, persistent ductus arteriosus and deaths. Sepsis and mechanical ventilation were more common in the group with PVL (23.5 and 2.7%, p = 0.005; 86 and 59%, p = 0.004, respectively. Both of these were identified as, independent risk factors for PVL by logistic regression (p = 0.027 and 0.015, respectively. CONCLUSIONS: Chorioamnionitis has been defined as a risk factor for PVL. We have demonstrated that neonatal sepsis is also an important risk factor. We believe that the systemic inflammatory response is the principal factor involved in the etiopathogenesis of PVL among VLBWI.

    The genital mycoplasma species, Ureaplasma parvum and Ureaplasma urealyticum are the most common organisms isolated from infected amniotic fluid and placentas, and they contribute to adverse pregnancy outcomes including preterm birth and neonatal morbidities. In our institution, almost half of the preterm infants of less than 32 weeks gestation are Ureaplasma-positive in one or more compartment (respiratory, blood and/or cerebrospinal fluid), indicating that these organisms are the most common pathogens affecting this population. This review will focus on the compelling epidemiological and experimental evidence linking perinatal Ureaplasma species exposure to important morbidities of prematurity, such as bronchopulmonary dysplasia, intraventricular haemorrhage and necrotising enterocolitis.

    Full Text Available Cervical necrotizing fasciitis is an unusual infection characterized by necrosis of the subcutaneous tissue and fascial layers. Risk factors for the development of necrotizing fasciitis include diabetes mellitus, chronic renal disease, peripheral vascular disease, malnutrition, advanced age, obesity, alcohol abuse, intravenous drug use, surgery, and ischemic ulcers. This report presents a case of necrotizing fasciitis in the cervical area caused by dental extraction in a 73-year-old woman. Cervical necrotizing fasciitis in geriatric patient is rare, and even when establishing the diagnosis and having it timely treated, the patient can suffer irreversible damage or even death. Clinical manifestations in the head and neck usually have an acute onset characterized by severe pain, swelling, redness, erythema, presence of necrotic tissue, and in severe cases obstruction of the upper airways. Therefore, the presentation of this clinical case can serve as guidance to dentists as a precaution to maintain an aseptic chain and be aware of the clinical condition of older patients and the systemic conditions that may increase the risk of infections.

    Necrotizing fasciitis is an infection of any layer of tissue compartment; it can be in the dermis, subcutaneous tissue, superficial fascia, deep fascia, or even muscle. Usually, necrotizing fasciitis is associated with necrotizing process caused by the single bacterial organism. The most common pathogen is group A Streptococcus. Delayed in the diagnosis and surgical treatment of necrotizing fasciitis will lead to increased tissue loss and high mortality risk. Here we report a case of necrotizing fasciitis which has a great outcome since the surgical exploration of tissue and debridement was done as soon as the patient is suspected of necrotizing fasciitis.

    2014-06-01

    Because of the paucity of reports and variability in the diagnostic criteria utilized, little is known regarding the natural outcome of patients with food protein-induced enterocolitis syndrome (FPIES). Data extracted from referenced manuscripts, as well as allergists' unpublished observations from across the globe, were used to form a cohesive opinion regarding its natural outcome. All authors concur that there is a generally high rate of recovery for FPIES. The most common foods causing FPIES are milk and soy. Depending upon which study is analyzed, by the age of 3-5 years, approximately 90% of patients recover from their disease. Recovery from FPIES to solid foods, occurs at a later age, but may reflect a later stage of introduction of the food into the diet. An important clinical outcome, although not common, is a shift from FPIES food hypersensitivity to an IgE-mediated food allergy. This necessitates a change in the oral food challenge protocol, if IgE-mediated sensitization is detected. Over the past several years, there has been an increasing awareness of FPIES. This knowledge should lead to a more timely diagnosis and should reassure parents and practitioners alike regarding its favorable course.

    Retinopathy of prematurity (ROP) is a multifactorial disease with evidence of many associated risk factors. Erythropoietin has been reported to be associated with this disorder in a murine model, as well as in humans in some single-center reports. We reviewed the data from two large tertiary NICUs in Italy to test the hypothesis that the use of erythropoietin may be associated with the development of the most severe stages of ROP in extremely low birth weight (ELBW) neonates. Retrospective study by review of patient charts and eye examination index cards on infants with birth weight large tertiary NICUs in Northern Italy (Sant'Anna Hospital NICU in Torino, and Ca' Foncello Hospital Neonatology in Treviso) in the years 2005 to 2007. Standard protocol of administration of EPO in the two NICUs consisted of 250 UI/kg three times a week for 6-week courses (4-week in 1001-1500g infants). Univariate analysis was performed to assess whether the use of EPO was associated with severe (threshold) ROP. A control, multivariate statistical analysis was performed by entering into a logistic regression model a number of neonatal and perinatal variables that - in univariate analysis - had been associated with threshold ROP. During the study period, 211 ELBW infants were born at the two facilities and survived till discharge. Complete data were obtained for 197 of them. Threshold retinopathy of prematurity occurred in 26.9% (29 of 108) of ELBW infants who received erythropoietin therapy, as compared with 13.5% (12 of 89) of those who did not receive erythropoietin (OR 2.35; 95% CI 1.121-4.949; p=0.02 in univariate analysis, and p=0.04 at multivariate logistic regression after controlling for the following variables: birth weight, gestational age, days on supplemental oxygen, systemic fungal infection, vaginal delivery).

    Full Text Available Necrotizing soft tissue infections (NSTI can be rapidly progressive and polymicrobial in etiology. Establishing the element of necrotizing infection poses a clinical challenge. A 64-year-old diabetic patient presented to our hospital with a gangrenous patch on anterior abdominal wall, which progressed to an extensive necrotizing lesion within 1 week. Successive laboratory risk indicator for necrotizing softtissue infections (LRINEC scores confirmed the necrotizing element. Cultures yielded Enterococci, Acinetobacter species and Apophysomyces elegans and the latter being considered as an emerging agent of Zygomycosis in immunocompromised hosts. Patient was managed with antibiotics, antifungal treatment and surgical debridement despite which he succumbed to the infection. NSTI′s require an early and aggressive management and LRINEC score can be applied to establish the element of necrotizing pathology. Isolation of multiple organisms becomes confusing to establish the etiological role. Apophysomyces elegans, which was isolated in our patient is being increasingly reported in cases of necrotizing infections and may be responsible for high morbidity and mortality. This scoring has been proposed as an adjunct tool to Microbiological diagnosis when NSTI′s need to be diagnosed early and managed promptly to decrease mortality and morbidity, which however may not come in handy in an immunocompromised host with polymicrobial aggressive infection.

There is a lack of research investigating its incidence in newborn infants in Oman and the Arab region. Therefore, this study aimed to assess the incidence of PNAC and its risk factors in Omani neonates. Methods: This retrospective study took place between January and April 2014. All neonates who received PN for ≥14 days during a four-year period (June 2009 to May 2013 at the neonatal intensive care unit (NICU in Sultan Qaboos University Hospital, Muscat, Oman, were enrolled. Results: A total of 1,857 neonates were admitted to the NICU over the study period and 135 neonates (7.3% received PN for ≥14 days. Determining the incidence of PNAC was only possible in 97 neonates; of these, 38 (39% had PNAC. The main risk factors associated with PNAC were duration of PN, duration of enteral starvation, gastrointestinal surgeries, blood transfusions and sepsis. Neonates with PNAC had a slightly higher incidence of necrotising enterocolitis in comparison to those without PNAC. Conclusion: This study found a PNAC incidence of 39% in Omani neonates. There were several significant risk factors for PNAC in Omani neonates; however, after logistic regression analysis, only total PN duration remained statistically significant. Preventive strategies should be implemented in NICUs so as to avoid future chronic liver disease in this population.

    Soft tissue infections are characterized by acute inflammation, diffuse edema, and suppuration, and are often associated with symptoms such as malaise, fever, tachycardia, and chills. Necrotizing fasciitis is a destructive bacterial infection affecting subcutaneous tissue and superficial fascia and is associated with high rates of mortality. It usually involves the abdomen and extremities, but it also can occur in the head and neck. Early diagnosis is critical and the most commonly accepted treatment includes radical surgical intervention and administration of broad-spectrum antibiotics. This article reports and discusses the case of a patient with odontogenic cervicofacial necrotizing fasciitis, and emphasizes the importance of early and effective treatment.

    Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030

    Full Text Available BACKGROUND Preterm premature rupture of membrane is defined as rupture of foetal membrane before onset of labour at less than 37 completed weeks of gestation. Incidence of PPROM is around 3-10% of all deliveries. Primary complication for mother is infection and for foetus and neonate is prematurity, foetal distress, cord compression, deformation, pulmonary hypoplasia, necrotising enterocolitis and neurologic disorders. Most likely outcome is preterm delivery within 1 week. The aim of the study is to study the foetomaternal and neonatal outcome in PPROM patients and the common prevalent organism in PPROM. MATERIALS AND METHODS This is a cohort study of pregnant women from 24-37 weeks with PPROM admitted to IMCH for a period of 1 year, January 2016 to December 2016. 100 patients with PPROM were taken up for the study. The data was collected using the following inclusion and exclusion criteria. Inclusion criteria are gestational age 24-37 weeks confirmed by dates, clinical examination and ultrasound with lack of uterine contractions for at least 1 hour from PPROM; single live pregnancy in vertex presentation; PPROM confirmed by direct visualisation, neonates admitted in NICU soon after delivery. RESULTS 49% of patients with preterm premature rupture of membranes were from 18-24 years.68% of patients had a latency period of 3 weeks.15% of patients had maternal tachycardia, 4% had tenderness of uterus and 4% had leucocytosis and 14% had an elevated CRP. Thus, clinical chorioamnionitis was seen in 14% of patients, 38% of babies born had prematurity and 2% had sepsis and 19% had respiratory distress syndrome and hyperbilirubinaemia, 2% had perinatal asphyxia, 2% had anomalies, 1% had necrotising enterocolitis and 5% were NND. Common organisms were normal flora, E. coli, Streptococci and Enterococci. CONCLUSION PPROM increases the incidence of maternal morbidity with longer hospital stay due to chorioamnionitis. Neonatal morbidity is increased due to

    Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

  4. Neonatal retinoblastoma

    Full Text Available From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary. At least one-half of infants with neonatal retinoblastoma have unilateral tumors when the diagnosis is made, typically the International Intraocular Retinoblastoma Classification (Murphree Group B or higher, but most germline mutation carriers will progress to bilateral involvement, typically Group A in the fellow eye. Neonatal leukokoria usually leads to the diagnosis in children without a family history of retinoblastoma, and a Group C tumor or higher is typical in the more advanced involved eye. Almost all infants with neonatal retinoblastoma have at least one eye with a tumor in proximity to the foveola, but the macula of the fellow eye is frequently spared. Consequently, loss of reading vision from both eyes is exceptional. A primary ectopic intracranial neuroblastic tumor known as trilateral retinoblastoma is no more common after neonatal than other retinoblastoma. For many reasons, neonatal retinoblastoma may be a challenge to eradicate, and the early age at diagnosis and relatively small tumors do not guarantee the preservation of both eyes of every involved child. Oncology nurses can be instrumental in contributing to better outcomes by ensuring that hereditary retinoblastoma survivors receive genetic counseling, by referring families of survivors to early screening programs when they are planning for a baby, and by providing psychological and practical support

    To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gas shadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer in four cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focal low density lesion suggestive of focal abscess was not visualized. Plain radiography is useful for early diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

    2008-12-01

    Full Text Available Introduction: Necrotizing fasciitis is a bacterial infection characterized by extensive necrosis of tissues, and may include skin and muscles. It's more frequent in adults than in children and generally involves the trunk and extremities. Head and neck area is less commonly affected. The most frequently isolated pathogens are the Streptococcus pyogenes (group A and Staphylococcus aureus. The anatomopathological exam is the best diagnostic method, which early identifies the disease. The clinical support, surgical debridement, and the intravenous antibiotic therapy, are fundamental for the treatment. Objective: To report a case of an infant who suffered from Cervical Necrotizing Fasciitis. Case Report: Infant, male sex, white, 2 months old, previously healthy, with Necrotizing Fasciitis involving the frontal and right lateral cervical regions. After adequate treatment the patient obtained excellent recovery without presenting important aesthetic or functional alterations. Conclusion: The Cervical Necrotizing Fasciitis is uncommon in children. The early surgical debridement is necessary to control the infection, even if it may result in great and deep injuries. The wide spectrum antibiotic therapy and hemodynamic support are also basic for the therapeutic success.

    Food protein-induced enterocolitis syndrome (FPIES) is an uncommon and potentially severe non IgE-mediated gastrointestinal food allergy. It is usually caused by cow's milk or soy proteins, but may also be triggered by ingestion of solid foods. The diagnosis is made on the basis of clinical history and symptoms. Management of acute phase requires fluid resuscitation and intravenous steroids administration, but avoidance of offending foods is the only effective therapeutic option.Infant with FPIES presented to our emergency department with vomiting, watery stools, hypothension and metabolic acidosis after ingestion of rice beverage. Intravenous fluids and steroids were administered with good clinical response. Subsequently, a double blind placebo control food challenge (DBPCFC) was performed using rice beverage and hydrolyzed formula (eHF) as placebo. The "rice based formula" induced emesis, diarrhoea and lethargy. Laboratory investigations reveal an increase of absolute count of neutrophils and the presence of faecal eosinophils. The patient was treated with both intravenous hydration and steroids. According to Powell criteria, oral food challenge was considered positive and diagnosis of FPIES induced by rice beverage was made. Patient was discharged at home with the indication to avoid rice and any rice beverage as well as to reintroduce hydrolyzed formula. A case of FPIES induced by rice beverage has never been reported. The present case clearly shows that also beverage containing rice proteins can be responsible of FPIES. For this reason, the use of rice beverage as cow's milk substitute for the treatment of non IgE-mediated food allergy should be avoided.

    Full Text Available Background: Intestinal obstruction is a life threatening condition in the newborn, with attendant high mortality rate especially in underserved subregion. This study reports the aetiology, presentation, and outcome of intestinal obstruction management in neonates. Materials and Methods: A prospective study of neonatal intestinal obstruction at the University of Benin Teaching Hospital, Benin, Nigeria, between January 2006-June 2008. Data were collated on a structured proforma and analysed for age, sex, weight, presentation, type/date of gestation/delivery, aetiology, clinical presentation, associated anomaly, treatment, and outcome. Results: There were 71 neonates, 52 were males and 19 were females (2.7:1. Their age range was between 12 hours and 28 days (mean, 7.9 ± 2.7 days and they weighed between 1.8 and 5.2 kg (average, 3.2 kg. The causes of intestinal obstruction were: Anorectal anomaly, 28 (39.4%; Hirschsprung′s disease, 8 (11.3%′ prematurity, 3 (4.2%; meconeum plug, 2 (2.8%; malrotation, 6 (8.5%; intestinal atresia, 8 (11.3%; necrotising enterocolitis (NEC, 4 (5.6%; obstructed hernia, 4 (5.6%; and spontaneous gut perforation, 3 (4.2%. Also, 27 (38% children had colostomy, 24 (33.8% had laparotomy, 9 (12.8% had anoplasty, while 11 (15.4% were managed nonoperatively. A total of 41 (57.7% neonates required incubator, 26 (36.6% needed total parenteral nutrition, while 15 (21.1% require d paediatric ventilator. Financial constraint, late presentation, presence of multiple anomalies, aspiration, sepsis, gut perforation, and bowel gangrene were the main contributors to death. Neonates with lower obstructions had a better outcome compared to those having upper intestinal obstruction ( P < 0.0001. Conclusion: Outcomes of intestinal obstruction are still poor in our setting; late presentation, financial constraints, poor parental motivation and lack of basic facilities were the major determinants of mortality.

    Paediatric and particularly neonatal neurosonography still remains a mainstay of imaging the neonatal brain. It can be performed at the bedside without any need for sedation or specific monitoring. There are a number of neurologic conditions that significantly influence morbidity and mortality in neonates and infants related to the brain and the spinal cord; most of them can be addressed by ultrasonography (US). However, with the introduction of first CT and then MRI, neonatal neurosonography is increasingly considered just a basic first line technique that offers only orienting information and does not deliver much relevant information. This is partially caused by inferior US performance – either by restricted availability of modern equipment or by lack of specialized expertise in performing and reading neurosonographic scans. This essay tries to highlight the value and potential of US in the neonatal brain and briefly touching also on the spinal cord imaging. The common pathologies and their US appearance as well as typical indication and applications of neurosonography are listed. The review aims at encouraging paediatric radiologists to reorient there imaging algorithms and skills towards the potential of modern neurosonography, particularly in the view of efficacy, considering growing economic pressure, and the low invasiveness as well as the good availability of US that can easily be repeated any time at the bedside.

    Walker, Suellen M

    2014-01-01

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    Decision-making on invasive intervention in patients with clinical signs of infected necrotizing pancreatitis is often related to the presence of gas configurations and the degree of encapsulation in necrotic collections on imaging. Data on the natural history of gas configurations and encapsulation in necrotizing pancreatitis are, however, lacking. A post hoc analysis was performed of a previously described prospective cohort in 21 Dutch hospitals (2004-2008). All computed tomography scans (CTs) performed during hospitalization for necrotizing pancreatitis were categorized per week (1 to 8, and thereafter) and re-assessed by an abdominal radiologist. A total of 639 patients with necrotizing pancreatitis were included, with median four (IQR 2-7) CTs per patient. The incidence of first onset of gas configurations varied per week without a linear correlation: 2-3-13-11-10-19-12-21-12%, respectively. Overall, gas configurations were found in 113/639 (18%) patients and in 113/202 (56%) patients with infected necrosis. The incidence of walled-off necrosis increased per week: 0-3-12-39-62-76-93-97-100% for weeks 1-8 and thereafter respectively. Clinically relevant walled-off necrosis (largely or fully encapsulated necrotic collections) was seen in 162/379 (43%) patients within the first 3 weeks. Gas configurations occur in every phase of the disease and develop in half of the patients with infected necrotizing pancreatitis. Opposed to traditional views, clinically relevant walled-off necrosis occurs frequently within the first 3 weeks.

    2015-01-01

    Full Text Available Paroxysmal nocturnal hemoglobinuria (PNH is a rare, progressive, and life-threatening hematopoietic stem cell disorder characterized by complement-mediated intravascular hemolysis and a prothrombotic state. Patients with PNH might have slightly increased risk of infections due to complement-associated defects subsequent to CD59 deficiency. Here, we report a rare case of a 65-year-old male patient with necrotic ulcers on both legs, where the recognition of pancytopenia and microthrombi led to the diagnosis of PNH based on FLAER (FLuorescent AERolysin flow cytometric analysis. He was subsequently started on eculizumab therapy, with starting and maintenance doses set as per drug labelling. Progression of the patient’s leg ulcers during follow-up, with fulminant tissue destruction, purulent discharge, and necrotic patches, led to a later diagnosis of necrotizing fasciitis due to Pseudomonas aeruginosa and Klebsiella pneumonia infection. Courses of broad-spectrum antibiotics, surgical debridement, and superficial skin grafting were applied with successful effect during ongoing eculizumab therapy. This case highlights the point that it is important to maintain treatment of underlying disorders such as PNH in the presence of life-threatening infections like NF.

E-mail: suellenramosvet@hotmail.com The sialometaplasia is a rare disease of unknown cause in dogs and cats, which usually affects the submandibular salivary gland, caused by trauma, physical-chemical or biological attack in blood vessels that can produce ischemic changes, causing necrosis, scaly inflammation and metaplasia of glandular epithelium and ducts. Animals affected by sialometaplasia necrotizing show pain, an increase in salivary glands and regional lymphadenopathy. Ultrasonography associated with biopsy of the affected tissue are effective in diagnosing the disease. The treatment is surgical and symptomatic. In this study, we tried to report the case of a half-breed dog, 6 years old, who presented the symptoms and histopathological diagnosis of necrotizing sialometaplasia.

    Structural brain abnormalities identified at near-term age have been recognized as potential predictors of neurodevelopment in children born preterm. The aim of this study was to examine the relationship between neonatal physiological risk factors and early brain structure in very-low-birth-weight (VLBW) preterm infants using structural MRI and diffusion tensor imaging (DTI) at near-term age. Structural brain MRI, diffusion-weighted scans, and neonatal physiological risk factors were analyzed in a cross-sectional sample of 102 VLBW preterm infants (BW ≤ 1500 g, gestational age (GA) ≤ 32 weeks), who were admitted to the Lucile Packard Children's Hospital, Stanford NICU and recruited to participate prior to routine near-term brain MRI conducted at 36.6 ± 1.8 weeks postmenstrual age (PMA) from 2010 to 2011; 66/102 also underwent a diffusion-weighted scan. Brain abnormalities were assessed qualitatively on structural MRI, and white matter (WM) microstructure was analyzed quantitatively on DTI in six subcortical regions defined by DiffeoMap neonatal brain atlas. Specific regions of interest included the genu and splenium of the corpus callosum, anterior and posterior limbs of the internal capsule, the thalamus, and the globus pallidus. Regional fractional anisotropy (FA) and mean diffusivity (MD) were calculated using DTI data and examined in relation to neonatal physiological risk factors including gestational age (GA), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), and sepsis, as well as serum levels of C-reactive protein (CRP), glucose, albumin, and total bilirubin. Brain abnormalities were observed on structural MRI in 38/102 infants including 35% of females and 40% of males. Infants with brain abnormalities observed on MRI had higher incidence of BPD (42% vs. 25%) and sepsis (21% vs. 6%) and higher mean and peak serum CRP levels, respectively, (0.64 vs. 0.34 mg/dL, p = .008; 1.57 vs. 0.67

    'Focal necrotizing pneumonia' was defined as a localized type of necrotizing pneumonia characterized by a single or few cavities of low density without rim enhancement on computed tomography (CT) scan. The purpose of this study was to investigate the clinical features and course of patients with focal necrotizing pneumonia, thereby elucidating its clinical relevance. The present study was conducted retrospectively in patients who had been interpreted as having lung abscess or necrotizing pneumonia on CT scan. Clinical and radiological characteristics were compared between the focal necrotizing pneumonia and lung abscess groups. Overall, 68 patients with focal necrotizing pneumonia (n = 35) or lung abscess (n = 33) were included in the present study. The frequency of risk factors for aspiration was significantly lower in the focal necrotizing group, compared with the lung abscess group (14.3% vs 45.5%, P = 0.005). Compared with lung abscess, focal necrotizing pneumonia was observed more commonly in non-gravity-dependent segments (66% vs 36%, P lung abscess group (31% vs 12%, P = 0.08). However, in terms of treatment outcomes, a similar high rate of success was observed in both groups: 97%, respectively. Compared to lung abscess, focal necrotizing pneumonia occurs more commonly in non-gravity-dependent segments with lower incidence of risk factors for aspiration. Similar to lung abscess, the rate of success for treatment of focal necrotizing pneumonia was high. © 2013 The Authors. Respirology © 2013 Asian Pacific Society of Respirology.

    Many premature infants are born without exposure to antenatal steroids (ANS) or with incomplete courses. This study evaluates the dose-dependent effect of ANS on rates of neonatal morbidities and early childhood neurodevelopmental outcomes of extremely premature infants. To compare rates of neonatal morbidities and 18- to 22-month neurodevelopmental outcomes of extremely premature infants exposed to no ANS or partial or complete courses of ANS. In this observational cohort study, participants were extremely premature infants (birth weight range, 401-1000 g; gestational age, 22-27 weeks) who were born at participating centers of the National Institute of Child Health and Human Development Neonatal Research Network between January 2006 and December 2011. Data were analyzed between October 2013 and May 2016. Rates of death or neurodevelopmental impairment at 18 to 22 months' corrected age. Neurodevelopmental impairment was defined as the presence of any of the following: moderate to severe cerebral palsy, a cognitive score less than 85 on the Bayley Scales of Infant and Toddler Development III, blindness, or deafness. There were 848 infants in the no ANS group, 1581 in the partial ANS group, and 3692 in the complete ANS group; the mean (SD) birth weights were 725 (169), 760 (173), and 753 (170) g, respectively, and the mean (SD) gestational ages were 24.5 (1.4), 24.9 (2), and 25.1 (1.1) weeks. Of 6121 eligible infants, 4284 (70.0%) survived to 18- to 22-month follow-up, and data were available for 3892 of 4284 infants (90.8%). Among the no, partial, and complete ANS groups, there were significant differences in the rates of mortality (43.1%, 29.6%, and 25.2%, respectively), severe intracranial hemorrhage among survivors (23.3%, 19.1%, and 11.7%), death or necrotizing enterocolitis (48.1%, 37.1%, and 32.5%), and death or bronchopulmonary dysplasia (74.9%, 68.9%, and 65.5%).

    Full Text Available La apendicitis neonatal es una patología infrecuente, de difícil diagnóstico y con una mortalidad elevada. Se han estudiado diversas teorías sobre su etiología que consideran que la apendicitis en el periodo neonatal podría corresponder a una manifestación de inmadurez inmunitaria. El cuadro clínico de apendicitis en este grupo etáreo no tiene las características clásicas, incluyendo signos y síntomas inespecíficos, que pueden corresponder a patologías más frecuentes como la enterocolitis necrotizante. La perforación intestinal constituye la complicación más frecuente y el diagnóstico se realiza usualmente de forma intraoperatoria. En el presente artículo, se describen dos neonatos con diagnóstico intraoperatorio de apendicitis, nacidos en la Clínica Universidad de La Sabana en el año 2016. En ellos, se destaca el cuadro clínico de presentación y manejo quirúrgico, los cuales permitieron identificar esta patología.

    Necrotizing fasciitis (NF) is uncommon and difficult to diagnose, and it cause progressive morbidity until the infectious process is diagnosed and treated medically and surgically. The literature addressed NF contains confusing information, inaccurate bacteriologic data, and antiquated antibiotic therapy. A delay in diagnosis is associated with a grave prognosis and increased mortality. The main goal of the clinician must be to establish the diagnosis and initially treat the patient within the standard of care. This review is planned as a guide for the clinician in making an early diagnosis of NF and initiating effective medical and surgical therapy.

    Cervico-facial necrotizing fasciitis is a potential complication of odontogenic infection that can lead to mediastinitis and septic shock. A delay or inappropriate treatment of simple infections and immunocompromise increase the risk of developing the disease and in turn increase the morbidity and mortality of the disease. We present two cases one of which we believe developed due to delayed treatment and the other due to immunocompromise. Both cases were successfully treated with surgical debridement and broad spectrum antibiotics. There is need to rethink certain clinical judgments such as treatment during pregnancy and the usefulness of an informative medical history from patients. (author)

    OBJECTIVE: To warn pediatricians about the early recognition of cholestasis in newborns and infants. METHODS: A bibliographic research about cholestasis was performed using Medline, and emphasizing the most relevant publications of the last 30 years. RESULTS: The concept of cholestasis and the causes of cholestatic tendency in newborns and infants are described. Several causes of intra and extrahepatic cholestasis are reported as well. In this review, only the diseases with diagnostic, therapeutic or prognostic peculiarities are commented, including extrahepatic biliary atresia, idiopathic neonatal hepatitis, galactosemia, and Alagille s syndrome. Furthermore, several resources are discussed for the diagnosis of cholestasis. CONCLUSIONS: The establishment of the diagnosis of cholestasis through the detection of hyperbilirubinemia in newborns who present jaundice after 14 days of life is a goal that could change the prognosis of several diseases responsible for neonatal cholestasis.

    Full Text Available Aim. This study was designed to analyse the results of two-stage arterial switch operation (ASO of “simple” transposition of great arteries in patients with infection, neurological problems or necrotizing enterocolitis, which preclude neonatal surgery. Methods. Transthoracic echocardiography data and outcomes of surgery were investigated in 19 patients (study group; #1 after two-stage ASO and 67 patients (control group; #2 after a single-stage ASO. Age of patients at the first stage was 27 (8–55 days and at the second stage 172 (92–256 days. Patients in group 2 were 7 (2–53 days old. All of them were followed up for 21 (4–49 months (group 1 and 40 (7–79 months (group 2 after arterial switch operation. Results. There was no operative mortality at both stages in group 1. The duration of ventilation, length of intensive care unit and hospital stay after surgery were considerably lower in group 1. Actuarial sur-vival and freedom from reoperation at 4 years in group 1 accounted for 100%, while in the con-trol group those indicators at 6 years ran to 98.5% and 94%, respectively. The only difference detected by echocardiography was the aortic valve hinge points Z-score (3.9±1.44 vs 3.1±1.27; p=0.025 and sinuses of Valsalva (3.8±1.41 vs 2.8±1.19; p=0.03, which were higher in the 1st group. There was no aortic regurgitation >1 grade in both groups. Conclusion. Two-stage repair of “simple” transposition of great arteries, when it’s necessary to delay arterial switch operation on the clinical grounds, can be performed with excellent clinical outcomes.

    Full Text Available In Western developed countries, Listeria monocytogenes is not an uncommon pathogen in neonates. However, neonatal listeriosis has rarely been reported in Taiwan. We describe two cases collected from a single medical institute between 1990 and 2005. Case 1 was a male premature baby weighing 1558 g with a gestational age of 31 weeks whose mother had fever with chills 3 days prior to delivery. Generalized maculopapular rash was found after delivery and subtle seizure developed. Both blood and cerebrospinal fluid culture collected on the 1st day yielded L. monocytogenes. In addition, he had ventriculitis complicated with hydrocephalus. Neurologic development was normal over 1 year of follow-up after ventriculoperitoneal shunt operation. Case 2 was a 28-weeks' gestation male premature baby weighing 1180 g. Endotracheal intubation and ventilator support were provided after delivery due to respiratory distress. Blood culture yielded L. monocyto-genes. Cerebrospinal fluid showed pleocytosis but the culture was negative. Brain ultrasonography showed ventriculitis. Sudden deterioration with cyanosis and bradycardia developed on the 8th day and he died on the same day. Neonatal listeriosis is uncommon in Taiwan, but has significant mortality and morbidity. Early diagnosis of perinatal infection relies on high index of suspicion in perinatal health care professionals. [J Formos Med Assoc 2007;106(2:161-164

    Full Text Available Necrotizing soft tissue fasciitis (NSTIs or necrotizing fasciitis is an infrequent and serious infection. Herein, we describe the clinical course of a female patient who received a diagnosis of NSTIs after gluteus intramuscular injection. We also report the results of our review of published papers from 1997 to 2017. Since now, 19 cases of NSTIs following intramuscular injections have been described. We focus on the correlation between intramuscular injection and NSTIs onset, especially in immunosuppressed patients treated with corticosteroids, suffering from chronic diseases or drug addicted. Intramuscular injections can provoke severe tissue trauma, representing local portal of infection, even if correctly administrated. Otherwise, it is important not to inject drug in subcutaneous, which is a less vascularized area and therefore more susceptible to infections. Likewise, a proper injecting technique and aspiration prior to injection seem to be valid measure to prevent intra-arterial or para-arterial drug injection with the consequent massive inflammatory reaction. Necrosis at the infection site appears to be independent of the drug, and it is a strong additional risk factor for NSTIs.

    A case of necrotizing pneumonia secordary to Fusobacterium necrophorum is reported. This anaerobic infection commonly originates in the upper respiratory tract and is often accompanied by multiple system disease due to hematogeneous seeding. When the lungs are involved, diffuse necrotizing pneumonia with pleural effusions and cavitation result. The course is prolonged, and the diagnosis is frequently delayed. With appropriate antibiotics, the prognosis is good.

    To analyze CT and follow-up chest radiographic findings in patients with necrotizing pneumonia and to evaluate clinical significance of the extent of necrosis. We reviewed medical records and retrospectively analysed CT scans and follow-up chest radiographs of 22 patients with necrotizing pneumonia, confirmed by biopsy (n = 7) and culture (n = 15). Inclusion criteria for necrotizing pneumonia was necrotic low attenuation, with or without cavitation on postcontrast enhanced CT scan. The study group included 15 men and seven women, aged 11-66 years (average: 47 years). The pathogens of necrotizing pneumonia were Klebsiella spp (n = 7), Enterobacter spp (n = 5), Actinomyces spp (n = 4), Pseudomonas spp (n = 4), Nocardia spp (n = 4), and others (n = 5). Average duration of pneumonia was 4.1 months. On CT scan, pneumonic consolidations were well-marginated in 14 patients and there were cavities on initial CT scan in 16 cases. Margins of the necrotic portion on CT scan were well-demarcated in majority of the patients (16/22). Low attenuation areas on initial CT scan resulted in cavitation, fibrosis and volume loss as shown on follow-up chest radiographs. The larger the necrotic areas on CT, the more the volume loss was. CT findings of necrotizing pneumonia were well-marginated air-space consolidation with low attenuation area, with or without cavity. The extent of necrotic area was closely related with the degree of fibrotic change later on. CT is important tool for diagnosis and prediction of parenchymal damage in necrotizing pneumonia

    2010-02-01

    Hypoglycemia in the newborn may be associated with both acute decompensation and long-term neuronal loss. Studies of the cause of hypoglycemic brain damage and the relationship of hypoglycemia to disorders associated with hyperinsulinism have aided in our understanding of this common clinical finding. A recent consensus workshop concluded that there has been little progress toward a precise numerical definition of neonatal hypoglycemia. Nonetheless, newer brain imaging modalities have provided insight into the relationship between neuronal energy deficiency and central nervous system damage. Laboratory studies have begun to reveal the mechanism of hypoglycemic damage. In addition, there is new information about hyperinsulinemic hypoglycemia of genetic, environmental, and iatrogenic origin. The quantitative definition of hypoglycemia in the newborn remains elusive because it is a surrogate marker for central nervous system energy deficiency. Nonetheless, the recognition that hyperinsulinemic hypoglycemia, which produces profound central nervous system energy deficiency, is most likely to lead to long-term central nervous system damage, has altered management of children with hypoglycemia. In addition, imaging studies on neonates and laboratory evaluation in animal models have provided insight into the mechanism of neuronal damage.

    Full Text Available Necrotizing sialometaplasia (NSM is a rare benign, inflammatory disease of both major and minor salivary glands, although more commonly reported in the minor glands of the palate. The characteristic clinical presentation can perplex the clinician and may be mistaken for a malignant neoplasm, such as mucoepidermoid carcinoma, as well as invasive squamous cell carcinoma. The clinical and histological similarity between this entity and a malignant lesion may result in unnecessary or mis-treatment. Though clinically mimics malignancy, NSM is considered to be a self-limiting disease, and takes about 3-12 weeks to resolve. Majority of the case resolves itself or by supportive and symptomatic treatment. Surgical intervention is rarely required in NSM except the diagnostic biopsy. Herein we report the clinical, histopathological feature and surgical management of a case of NSM of hard palate in a young adult male.

    Necrotizing sialometaplasia (NS) which mimics malignancy both clinically and histopathologically is an uncommon benign, self-limiting inflammatory disease of the mucus-secreting minor salivary glands. The lesion is believed to be the result of vascular ischemia that may be initiated by trauma. Till date, the diagnosis of NS remains a challenge. This report demonstrates a case of NS in a 73-year-old male patient who presented with an ulcerative lesion in his palate. He had a history of local trauma and was long-term user of salbutamol inhaler. An incisional biopsy was carried out and the diagnosis was established through history, clinical examination, histopathology using Hematoxylin and Eosin stain. The patient was given symptomatic treatment and the lesion healed in about 7 weeks.

    Full Text Available Myositides comprise a large group of disorders involving limb muscle weakness. In differential diagnosis we have to consider idiopathic myositides, myositides associated with other diseases, and those induced by external factors, e.g. drug-induced. Statins are commonly used drugs, but many patients experience a broad spectrum of adverse effects including symptoms from skeletal muscle. Physicians should pay special attention to patients reporting muscle weakness lasting longer than 12 weeks, despite statin withdrawal, as well as other symptoms: dysphagia, disturbed grip function, elevated creatinine kinase (CK levels and abnormal electromyography. The reported case deals with the problem of differential diagnosis of drug-induced muscle injury, polymyositis with a recently reported myopathy – statin-induced autoimmune necrotizing myositis, related to anti-HMGCR antibodies.

    Full Text Available Pure white cell aplasia (PWCA is a rare hematologic disorder characterized by the absence of neutrophil lineages in the bone marrow with intact megakaryopoiesis and erythropoiesis. PWCA has been associated with autoimmune, drug-induced, and viral exposures. Here, we report a case of a 74-year-old female who presented with severe proximal weakness without pain and was found to have PWCA with nonspecific inflammatory necrotizing myositis and acute liver injury on biopsies. These findings were associated with a recent course of azithromycin and her daily use of a statin. Myositis improved on prednisone but PWCA persisted. With intravenous immunoglobulin and granulocyte-colony stimulating factor therapies, her symptoms and neutrophil counts improved and were sustained for months.

    Necrotizing fasciitis is a serious infection that originates in the subcutaneous tissues. Although many reports have been published about necrotizing infections of other anatomical sites, retroperitoneal necrotizing soft tissue infection is a rare entity that has been described in only a few case reports. The etiology and clinical course of retroperitoneal necrotizing fasciitis can be variable and it is often difficult to identify the etiology of the infective process. We report a 58-year-old man with rapidly progressive, gas-producing, necrotizing inflammation in the retroperitoneum, complicated with genital involvement resembling Fournier gangrene. The patient was managed successfully by aggressive drainage, debridement, and sequential laparotomies to track and control the extensive necrosis of the retroperitoneum and perineum, in addition to systemic care to control sepsis. After his general condition stabilized, early rectosigmoid adenocarcinoma was identified and resected curatively. He remained well at follow up, six months after discharge. In retrospect, the trigger of the disease process was unclear. Although it was believed possibly to be due to the colon lesion, adenocarcinoma of the rectosigmoid colon was identified and the patient was managed successfully. Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

    Necrotizing colitis associated with carcinoma of the colon, known also as obstructive colitis, is a disorder characterized by anulceration and inflammation of the colon proximal to an obstructive lesion, especially carcinoma of the rectosigmoid colon, and in rare instance, leads to acute gangrene of the colon. The authors analyzed radiologic findings in four cases of necrotizing colitis associated with carcinoma of the colon. Barium enema disclosed mucosal edema, nodular filling defects, irregularity of the colonic contour and typical thumbprinting appearance of involved colon proximal to an obstructing carcinoma of the colon. The mechanism of necrotizing colitis was briefly reviewed

    Full Text Available Necrotizing sialometaplasia is a benign, self-limiting, reactive inflammatory disorder of the salivary tissue, which mimics malignancy both clinically and histopathologically. The etiology is unknown, although it most likely represents a local ischemic event, infectious process or perhaps an immune response to an unknown allergen. A case of necrotizing sialometaplasia of the palate in a 40-year-old male patient is presented. Histopathological examination is necessary for the diagnosis of necrotizing sialometaplasia because the clinical features of this condition can mimic other diseases, particularly malignant neoplasms.

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

    Full Text Available Background : Necrotizing fasciitis (NF is a surgical emergency. It is a rapidly progressing infection of the fascia and subcutaneous tissue and could be fatal if not diagnosed early and treated properly. NF is common in the groin, abdomen, and extremities but rare in the neck and the head. Cervical necrotizing fasciitis (CNF is an aggressive infection of the neck and the head, with devastating complications such as airway obstruction, pneumonia, pulmonary abscess, jugular venous thrombophlebitis, mediastinitis, and septic shock associated with high mortality. Aim : To assess the presentation, comorbidities, type of infection, severity of disease, and intensive care outcome of CNF. Methods : Medical records of the patients treated for NF in the surgical intensive care unit (SICU from January 1995 to February 2005 were reviewed retrospectively. Results : Out of 94 patients with NF, 5 (5.3% had CNF. Four patients were male. The mean age of our patients was 41.2 ± 14.8 years. Sixty percent of patients had an operative procedure as the predisposing factor and 80% of patients received nonsteroidal anti-inflammatory drugs (NSAIDs. The only comorbidity associated was diabetes mellitus (DM in 3 patients (60%. Sixty percent of the cases had type1 NF. Mean sequential organ failure assessment (SOFA score on admission to the ICU was 8.8 ± 3.6. All patients had undergone debridement at least two times. During the initial 24 h our patients received 5.8 ± 3.0 l of fluid, 2.0 ± 1.4 units of packed red blood cells (PRBC, 4.8 ± 3.6 units of fresh frozen plasma (FFP, and 3.0 ± 4.5 units of platelet concentrate. The mean number of days patients were intubated was 5.2 ± 5.1 days and the mean ICU stay was 6.4 ± 5.2 days. Sixty percent of cases had multiorgan dysfunction (MODS and one patient died, resulting in a mortality rate of 20%. Conclusion : According to our study, CNF represents around 5% of NF patients. CNF was higher among male patients and in

  2. Intestinal upregulation of melanin-concentrating hormone in TNBS-induced enterocolitis in adult zebrafish.

    Full Text Available BACKGROUND: Melanin-concentrating hormone (MCH, an evolutionarily conserved appetite-regulating neuropeptide, has been recently implicated in the pathogenesis of inflammatory bowel disease (IBD. Expression of MCH is upregulated in inflamed intestinal mucosa in humans with colitis and MCH-deficient mice treated with trinitrobenzene-sulfonic acid (TNBS develop an attenuated form of colitis compared to wild type animals. Zebrafish have emerged as a new animal model of IBD, although the majority of the reported studies concern zebrafish larvae. Regulation MCH expression in the adult zebrafish intestine remains unknown. METHODS: In the present study we induced enterocolitis in adult zebrafish by intrarectal administration of TNBS. Follow-up included survival analysis, histological assessment of changes in intestinal architecture, and assessment of intestinal infiltration by myeloperoxidase positive cells and cytokine transcript levels. RESULTS: Treatment with TNBS dose-dependently reduced fish survival. This response required the presence of an intact microbiome, since fish pre-treated with vancomycin developed less severe enterocolitis. At 6 hours post-challenge, we detected a significant influx of myeloperoxidase positive cells in the intestine and upregulation of both proinflammatory and anti-inflammatory cytokines. Most importantly, and in analogy to human IBD and TNBS-induced mouse experimental colitis, we found increased intestinal expression of MCH and its receptor in TNBS-treated zebrafish. CONCLUSIONS: Taken together these findings not only establish a model of chemically-induced experimental enterocolitis in adult zebrafish, but point to effects of MCH in intestinal inflammation that are conserved across species.

    Full Text Available Necrotizing fasciitis, caused by Streptococcus pneumoniae, is an extremely rare and life-threatening bacterial soft tissue infection. We report a case of early necrotizing fasciitis associated with Streptococcus pneumoniae infection in a 26-year-old man who was immunocompromised with mixed connective tissue disease. The patient presented with acute, painful, erythematous, and edematous skin lesions of his right lower back, which rapidly progressed to the right knee. The patient underwent surgical exploration, and a diagnosis of necrotizing fasciitis was confirmed by pathological evidence of necrosis of the fascia and neutrophil infiltration in tissue biopsies. Cultures of fascial tissue biopsies and blood samples were positive for Streptococcus pneumoniae. To our knowledge, this is the first report of necrotizing fasciitis resulting from Streptococcus pneumoniae diagnosed at early phase; the patient recovered well without surgical debridement.

    Full Text Available Spontaneous pneumothorax is a serious complication of pulmonary tuberculosis that requires immediate treatment. Necrotizing fasciitis is a serious, rapidly progressive infection of the subcutaneous tissue and fascia, most related to trauma or surgery. Here, we report a case of pulmonary tuberculosis with spontaneous pneumothorax. A standard procedure of tube thoracostomy was performed for lung re-expansion. Two days after the tube was removed, necrotizing fasciitis developed from the puncture site. Computed tomography of the chest showed focal thickness with gas formation and loss of the fat plane over the chest wall, which is compatible with the diagnosis of necrotizing fasciitis. Aggressive treatment was given, including emergency fasciectomy and adequate systemic antibiotic and antituberculous treatment. The necrotizing fasciitis was successfully treated. The patient was discharged and sent home with maintenance antituberculous therapy.

    Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal allergic disorder. Large population-based FPIES studies are lacking. We sought to determine the incidence and clinical characteristics of FPIES in Australian infants. An Australia-wide survey (2012-2014) was undertaken through the Australian Paediatric Surveillance Unit, with monthly notification of new cases of acute FPIES in infants aged less than 24 months by 1400 participating pediatricians. Two hundred thirty infants with FPIES were identified. The incidence of FPIES in Australian infants (disease and FPIES to fruits, vegetables, or both. Crown Copyright © 2017.

    Food protein-induced enterocolitis syndrome (FPIES) is a non IgE-mediated gastrointestinal food allergic disorder. Some diagnostic criteria have been published for acute FPIES. Of course, they are not all the same, so the clinician must choose which ones to adopt for his/her clinical practice. We present here a brief review of these criteria and, through two clinical cases, show how the choice of one or the other can change the diagnostic destiny of a child with suspect FPIES.

    Full Text Available A 49-year-old male presented to the emergency with hematuria and pain in the shaft of the penis for one day. The patient was found to be in a state of shock. The shaft of the penis and the scrotum were swollen and tender. No skin necrosis was observed and no crepitus was palpable. Serum white count (WBC was 29.5 × 103/μL. A CT scan showed gas in the corpus spongiosum. Antibiotics were started with IV metronidazole, vancomycin, and piperacillin/tazobactam. Metronidazole was then replaced by clindamycin. Exploration was performed but no necrotic tissue was identified. Cystourethroscopy revealed dusky looking urethra. A suprapubic tube and a urethral catheter were placed in the bladder. WBC trended down to 13.9 × 103/μL on the fourth postoperative day. Urine culture grew Aerococcus urinae and blood cultures grew Alpha Hemolytic Streptococcus. On the sixth day, the patient was feeling worse and WBC increased. MRI revealed absent blood flow to the corpus spongiosum. Urethroscopy revealed necrosis of the urethra. Urethrectomy was performed via perineal approach. The patient immediately improved. The patient was discharged on the sixth postoperative day to continue ampicillin/sulbactam IV every 6 hours for a total of 4 weeks from the day of urethrectomy.

    A multicenter study of acute necrotizing pancreatitis (ANP) classified in accordance with the Balthazar criteria (grades D and E), has been performed in 12 teaching hospitals. A total of 233 patients were reviewed, and the mortality rate was 26.6%. The most common etiology was biliary pancreatitis (45.5%). Among the complications, shock, renal insufficiency, pulmonary insufficiency and hemorrhagic gastritis were associated with a mortality rate of 51-66%. Diffuse fluid collections were associated with a higher mortality rate (26.8%) than localized fluid collections (14.5%). In 106 patients with gallstone pancreatitis, early surgery was performed in 17, and 5 patients (29.4%) died. No mortality was observed in 32 patients with delayed surgery. Sphincterotomy was performed in 13 patients, and 4 (30.7%) died. Early surgery (necrosectomy and closed peritoneal lavage) was undertaken in 75 patients, with a mortality rate of 39%. In conclusion, the morbidity and mortality rates of ANP can be improved with proper monitoring, adequate supportive care and the judicious use of surgery based on clinical and morphological findings.

    Purpose: To evaluate the intra-arterial infusion of pancreatic enzyme inhibitor and antibiotics in the treatment of acute necrotizing pancreatitis (ANP). Method: 23 patients with ANP were treated by arterial infusion, by placing a catheter in the celiac artery, spleen artery or gastroduodenal artery. 5-Fu and antibiotics was used continuously for 6 to 20 days. According to the site of the inflammation on the CT scan, the top of the catheter was positioned in the celiac artery in 21 cases, splenic artery in one, and gastroduodenal artery in one. Results: The mortality rate in this study was 0% and no procedure related complication was observed. 20 of 23 patients had good effect without severe complications. In 2 cases, drainage of parapancreatic abscess was performed after improvement of the acute inflammation with the arterial infusion antibiotics, one patient died of multi-organ failure before arterial infusion was started. Conclusion: Arterial infusion therapy of 5-Fu and antibiotics for ANP offers good therapeutic effect and creates the possibility for subsequent operation on abscess

    Acute necrotizing encephalopathy (ANE) is a rare but distinctive type of acute encephalopathy with global distribution. Occurrence of ANE is usually preceded by a virus-associated febrile illness and ensued by rapid deterioration. However, the causal relationship between viral infections and ANE and the exact pathogenesis of ANE remain unclear; both environmental and host factors might be involved. Most cases of ANE are sporadic and nonrecurrent, namely, isolated or sporadic ANE; however, few cases are recurrent and with familial episodes. The recurrent and familial forms of ANE were found to be incompletely autosomal-dominant. Further the missense mutations in the gene encoding the nuclear pore protein Ran Binding Protein 2 (RANBP2) were identified. Although the clinical course and the prognosis of ANE are diverse, the hallmark of neuroradiologic manifestation of ANE is multifocal symmetric brain lesions which are demonstrated by computed tomography (CT) or magnetic resonance imaging (MRI). The treatment of ANE is still under investigation. We summarize the up-to-date knowledge on ANE, with emphasis on prompt diagnosis and better treatment of this rare but fatal disease. PMID:25873770

    2009-12-01

    Despite advances in the care of infants, there remain many newborns whose medical conditions are incompatible with sustained life. At times, healthcare providers and parents may agree that prolonging life is not an appropriate goal of care, and they may redirect treatment to alleviate suffering. While pediatric palliative treatment protocols are gaining greater acceptance, there remain some children whose suffering is unrelenting despite maximal efforts. Due to the realization that some infants suffer unbearably (ie, the burdens of suffering outweigh the benefits of life), the Dutch have developed a protocol for euthanizing these newborns. In this review, I examine the ethical aspects of 6 forms of end of life care, explain the ethical arguments in support of euthanasia, review the history and verbiage of the United States regulations governing limiting and withdrawing life-prolonging interventions in infants, describe the 3 categories of neonates for whom the Dutch provide euthanasia, review the published analyses of the Dutch protocol, and finally present some practical considerations should some form of euthanasia ever be deemed appropriate.

    Full Text Available Dilek Sarici1, S Umit Sarici21Kecioren Research and Education Hospital, Kecioren, Ankara, 2Chief of Division of Neonatology, Division of Neonatology, Department of Pediatrics, Gulhane Military Medical Academy, Ankara, TurkeyAbstract: In this article, distribution of potassium (K+ in body fluids, pathophysiology, causes, clinical signs and symptoms, and the evaluation and treatment of neonatal hypokalemia are reviewed. K+ is the most important intracellular cation and normal serum K+ is stabilized between 3.5 and 5.5 mEq/L. Hypokalemia may be caused by increased renal losses, increased extrarenal (gastrointestinal losses, redistribution or prolonged insufficient K+ intake. Clinical signs and symptoms occur as the result of functional changes in striated muscle, smooth muscle, and the heart. Hypokalemia is usually asymptomatic when K+ levels are between 3.0 and 3.5 mEq/L; however, there may sometimes be slight muscle weakness. Moderate hypokalemia is observed when serum K+ is between 2.5 and 3.0 mEq/L. Proximal muscle weakness is observed most commonly in lower extremities; cranial muscles are normal, but constipation and distention are prominent. Severe hypokalemia develops when serum K+ falls below 2.5 mEq/L. Rhabdomyolysis, myoglobinuria, severe muscle weakness, paralysis, respiratory distress, and respiratory arrest are observed. The clinical signs and symptoms may be unremarkable in cases of chronically developing hypokalemia; however, appropriate treatment is essential when serum K+ level falls below 2.5 mEq/L as the most dangerous complication of hypokalemia is fatal cardiac arrythmia, and changes visible with electrocardiography may not always correlate with the level of hypokalemia. Sodium (Na+, K+, chloride (Cl-, bicarbonate, creatinine, blood sugar, magnesium (Mg, plasma renin activity, aldosterone, and blood gases should be investigated by laboratory testing.

She received 60 Gy irradiation post hysterectomy and ovariectomy due to uterine cancer at the age of 39 y. She suffered from fecal incontinence and anal pain at 58 y, was diagnosed to have radiation colitis. She was hospitalized due to neurosis, anal pain and hypertension at 59 y. She received nephrostomy due to hydronephrosis and ureterostenosis at 60 y, and colostomy and ileal conduit formation due to anal pain and dyschezia. Case 2: A 70 years old female who received 60 Gy irradiation post surgery similar to case 1 at the age of 61 y. She suffered from ileus, intestinal retention and hydronephrosis thereafter. She was hospitalized due to metastasis of the cancer to sacred bone, and received further 40 Gy radiation therapy at the age of 65 y. Up to the present, she received several operations such as ileostomy, nephrostomy and hemorrhoids excision. It is important for surgeons to understand the actual QOL of patients with radiation enterocolitis. (K.H.)

    Yersinia enterocolitica is a gram-negative bacillus that can cause illness ranging from a self-limiting enterocolitis to life-threatening bacteremia. Y. enterocolitica biotype 1B, serotype O:8 (1B/O:8), is the most pathogenic of the Yersinia species because of the presence of the high-pathogenicity island and the Yersinia virulence plasmid (pYV). Here, we report a pediatric case of Y. enterocolitica 1B/O:8 bacteremia and enterocolitis. A 20-month-old girl was admitted to hospital with fever,pharyngitis, and abdominal pain on day 2. Blood culture on admission was positive for Y. enterocolitica 1B/O:8. Stool culture on day 5 after cefotaxime treatment was also positive for Y. enterocolitica 1B/O:8, but only after cold enrichment at 4°C for 3 weeks. PCR assays identified the pYV only in stool specimens, indicating that strains from routine blood culture at 37°C lacked the pYV. The present case showed the usefulness of stool culture with cold enrichment and agglutination test for the diagnosis of Y. enterocolitica infection. We would therefore like to emphasize the importance of collection and preservation of stool specimens for the identification of pYV. To our knowledge, this is the first reported pediatric case of Y. enterocolitica 1B/O:8 bacteremia.

    Full Text Available Introduction. Necrotizing soft tissue infection (NSTI is a life-threatening condition, characterized by widely spread necrosis of skin, subcutaneous fat, fascia and muscles. Treatment involves surgical debridement and broad-spectrum antimicrobial therapy. Mortality is still high due to diagnostic delays. NSTI is rare in general population, there are even less literature data of this condition in pregnancy. Timely diagnosis and therapy is crucial for outcome of these patients. Clinicians should have in mind NSTI in patients with perianal infections, especially in cases where immunosuppressive role of pregnancy is present. Case outline. We present a case of a 21-year-old pregnant woman with NSTI spreading from perianal region. The patient was admitted to hospital in the 31st week of otherwise healthy twin pregnancy one day after incision of perianal abscess. At admission she was examined by a gynecologist; vital signs were stable, laboratory results showed the presence of infection. She was referred for another surgical procedure and broad-spectrum antibiotics were prescribed. The next morning the patient complained of intense abdominal pain. Clinical exam revealed only discrete redness of the skin tender on palpation, crepitating. She was immediately referred to surgery. Intraoperative findings revealed massive soft tissue infection spreading up to the chest wall. Wide skin incisions and debridement were performed. The patient developed septic shock and after initial resuscitation gynecologist confirmed intrauterine death of twins and indicated labor induction. Over the next few days the patient’s general condition improved. On several occasions the wounds were aggressively debrided under general anesthesia, which left the patient with large abdominal wall defect. Twenty-three days after the initial operation, the defect was reconstructed with partial-thickness skin grafts, providing satisfactory results. Conclusion. Diagnosis and outcome of

    The clinical examination of the CNS in the neonate is often difficult in cases of complex pathology. Diagnostic imaging of the neonatal brain has become extremely useful and in the last decade has developed in two main directions: CT and US. MR imaging has been used recently with varying success in the diagnosis of pathology in the neonatal brain. Despite technical difficulties, this imaging method is likely to become increasingly important in the neonate. The paper examines the normal neonatal brain anatomy as seen with the different modalities, followed by pathologic conditions. Attention is directed to the common pathology, in asphyxiated newborns, the patholphysiology of intraventicular hemorrhage and periventricular leukomalacia in the preterm neonate, and hypoxic-ischemic brain injury in the term neonate. Pitfalls, artifacts, and problems in image interpretation are illustrated. Finally, the subsequent appearance of neonatal pathology later in infancy and childhood is discussed

    Streptococcal necrotizing myositis, also known as gangrenous myositis, is a very rare and severe soft tissue infection that predominately involves skeletal muscle and, eventually, superficial fascia and surrounding tissues. The presentation is often nonspecific until the rapidly progressing clinical course becomes apparent. A high morbidity and mortality rate has been reported in the small number of cases since 1900. Despite several attempts to better define the different entities causing necrotizing myositis, no single definitive causal relationship has been defined. A review of the literature is presented here to help clinicians distinguish those with necrotizing myositis from those with nonnecrotizing myositis when the clinician is at all confronted with the suspicion for such an infection. The case presented is that of a 48-year-old woman who had streptococcal necrotizing myositis. She died roughly 72 h after admission. After the patient's death, the clinical team sought consent for autopsy. Hospital staff made contact with family, and information was obtained from the family that the onset of the patient's symptoms was allegedly temporally related to her acquisition of a new tattoo on the right back, where the tattoo process allegedly included injection of cremated ashes of a pet dog. A high level of suspicion for necrotizing myositis must be maintained for a patient with unexplained severe muscle pain and soft tissue swelling accompanied by systemic inflammatory response syndrome.

    The aims of this paper were to review our experience with necrotizing fasciitis at Middlemore Hospital and to define the trends in incidence, inpatient mortality and microbiological profile. A computerized search of the electronic medical records was undertaken to identify adult patients with a diagnosis of necrotizing fasciitis between January 2000 and December 2010. A retrospective review of the clinical records was performed. Of the 138 patients with necrotizing fasciitis identified, 129 had their diagnosis confirmed at operation. The mortality at 30 days was 20.3% (95% confidence interval (CI) 13.9%-28.0%). There was a significant reduction in hospital mortality in each successive year of the study period with an odds ratio of 0.84 (95% CI 0.71-0.98, P = 0.03). A pattern of increasing incidence was noted until February 2004 (95% CI September 2002-July 2005). This was followed by a significant decrease in incidence. The empirical antibiotic regime of clindamycin, gentamicin and penicillin provides satisfactory cover against 95% of the causative pathogens. This represents the largest single-centre published case series in New Zealand. Despite concerns of increasing incidence and mortality associated with necrotizing fasciitis in New Zealand, the experience in South Auckland shows a decrease in incidence of necrotizing fasciitis since 2004 and a statistically significant decreasing trend in hospital mortality. © 2015 Royal Australasian College of Surgeons.

    Full Text Available Background: Although the mortality rate for preterm infants and the gestational age-specific mortality rate have dramatically improved over the last 3 to 4 decades, infants born preterm remain vulnerable to many complications, including respiratory distress syndrome, chronic lung disease, necrotizing enterocolitis, a compromised immune system, cardiovascular disorders, hearing and vision problems, and brain lesions. The aim is to determine mortality and morbidity rates and selected outcome variables for preterm infant’s grade 3 IVH or PVL 16.6%, NEC Bell stages II or III 9.8%, BPD 25/72 (33.3% of infants who survived to 36 weeks postmenstrual age. In 38 (37.2% infants, episodes of infections were noticed (one or more episodes in 25 infants, half of them were caused by Gram positive bacteria, most frequent coagulasa negative staphylococci. Klebsiella pneumoniae was the most frequent organism among Gram negative bacteria. One patient had invasive candidiasis caused by Candida albicans. In 5 infants (4.9% early onset of sepsis was documented. Conclusion: Very preterm infants remain very vulnerable group of population, and interventions to reduce the morbidity and mortality of preterm babies include tertiary interventions such as regionalized care, transportation in uterus, and treatment with antenatal steroids.

  5. Antibiotics in acute necrotizing pancreatitis --- perspective of a developing country

    2010-01-01

    Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases. Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed. Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration of 10 to 14 days if no systemic complications are present. In a developing country where the cost of managing complications of pancreatitis can be a limiting factor for patients, the use of prophylactic antibiotics early on in the disease in selected cases can be beneficial.

    2013-02-22

    We report necrotizing scleritis as a serious complication of a cosmetic eye whitening procedure that involves the use of intraoperative and postoperative topical mitomycin C. This is a single case report. A 59-year-old Caucasian male with a history of blepharitis status post uncomplicated LASIK refractive surgery reported chronic conjunctival hyperemia for 15 years prior to undergoing a cosmetic eye whitening procedure. He presented to our clinic 12 months after the cosmetic eye whitening procedure with progressive bilateral necrotizing scleritis and scleral calcification. Chronic conjunctival hyperemia may prompt patients to seek surgical correction with cosmetic eye whitening procedures. However, conjunctival hyperemia secondary to tear deficiency and evaporative dry eye may predispose to poor wound healing. Serious complications including necrotizing scleritis may result from cosmetic eye whitening procedures and the use of topical mitomycin C.

    2009-08-01

    A 67-year-old woman with insuline-dependent diabetes mellitus and chronic alcohol abuse was admitted with impaired consciousness and fever. Physical examination showed a livid induration of the perineal and vaginal soft tissues with crepitations. Laboratory tests showed greatly elevated infection parameters. Abdominal computed tomography revealed perineal and vaginal subcutaneous gas accumulation extending into the ventral abdominal wall. The combination of an obscure infection and subcutaneous genital gas accumulation suggested the diagnosis of Fournier gangrene, a necrotizing fasciitis. In spite of administration of broad-spectrum antibiotics and repeated surgical removal of necrotic tissue the patient died of multiple organ failure. Successful treatment of Fournier gangrene critically depends on immediate treatment. Administration of broad-spectrum antibiotics and aggressive surgical resection of the necrotic tissue may prevent continuing spreading of the infection. Computed tomography provides an early diagnosis and guides the presurgical evaluation of the subcutaneous spread. Georg Thieme Verlag KG Stuttgart * New York.

    Necrotizing fasciitis is a rapidly progressive destructive soft tissue infection with high mortality. Streptococcus pneumoniae as etiologic agent of necrotizing fasciitis is extremely unusual. The increased susceptibility to Streptococcus pneumoniae infection in patients with systemic lupus erythematosus is probably a multifactorial phenomenon. We report a case of a patient, a 36-year-old Caucasian female with 8-year history of systemic lupus erythematosus who presented a fatal Streptococcus pneumoniae necrotizing fasciitis. The role of computed tomography and the high performance of blood cultures for isolation of the causative microorganism are emphasized. Once diagnosis is suspected, empiric antibiotic treatment must be prescribed and prompt surgical exploration is mandatory. © The Author(s) 2015.

    catheter (88.9%, parenteral nutrition (64.8% and mechanical ventilation (61.1%. Staphylococcus epidermidis was the most frequently isolated species (77.8% and more often associated with infection (86.7% than with contamination (68.4%. Other species of CNS, including two strains of S. haemolyticus, three strains of S. lugdunensis, one strain of S. simulans, one strain of S. warneri and one strain of S. xylosus were also isolated from infants with clinical evidence of pneumonia, necrotizing enterocolitis and sepsis Conclusions: most newborns infected by CNS presented important risk factors for infection onset, including birthweight < 1,500g, foreign body presence and previous use of antibiotics. The identification of CNS species constitutes a useful marker of infection, since S. epidermidis was the species more frequently associated with infection.

    A 66-year-old woman presented with a 1-day history of sudden onset of generalised abdominal pain associated with fever and vomiting. She was previously diagnosed with left breast cancer 2 months ago and completed a course of chemotherapy 1 week prior to presentation. She was clinically unwell with generalised tenderness in her abdomen. Blood investigations showed severe neutropenia. A CT scan was requested which reported a marked oedematous swelling of the transverse colon with features suggestive of a contained perforation. The decision was made to operate. Intraoperatively, the transverse colon was found to be thickened with omentum adherent focally around the distal third. A right hemicolectomy was performed with an end ileostomy and mucus fistula. The patient made a successful recovery and was discharged within 7 days of presenting. Pathology reported typical features of neutropenic enterocolitis affecting the transverse colon with a normal terminal ileum, caecum and ascending colon.

    Full Text Available Necrotizing sialometaplasia is a rare benign and self-limiting disease, which commonly affects the minor salivary glands. Typically, it involves the seromucinous glands located at palate, buccal mucosa, tongue, tonsil, nasal cavity, trachea, larynx, maxillary sinus, and retromolar trigone. We report two such cases of necrotizing sialometaplasia to create awareness among the pathologists and surgeons because of its close morphological and clinical resemblance to squamous cell carcinoma. We have also documented that, the ischemic necrosis of salivary gland is the result of a vasculitic process.

    Full Text Available Cutaneous infections caused by Mycobacterium marinum have been attributed to aquarium or fish exposure after a break in the skin barrier. In most instances, the upper limbs and fingers account for a majority of the infection sites. While previous cases of necrotizing soft tissue infections related to M. marinum have been documented, the importance of our presenting case is to illustrate the aggressive nature of M. marinum resulting in a persistent necrotizing soft tissue infection of a finger that required multiple aggressive wound debridements, followed by an amputation of the affected extremity, in order to hasten recovery.

    Allergic enterocolitis, also known as food protein-induced enterocolitis syndrome (FPIES), is an increasingly reported and potentially severe non-IgE mediated food allergy of the first years of life, which is often misdiagnosed due to its non-specific presenting symptoms and lack of diagnostic guidelines. We sought to determine the knowledge of clinical, diagnostic and therapeutic features of FPIES among Italian primary-care paediatricians. A 16-question anonymous web-based survey was sent via email to randomly selected primary care paediatricians working in the north of Italy. There were 194 completed surveys (48.5% response rate). Among respondents, 12.4% declared full understanding of FPIES, 49% limited knowledge, 31.4% had simply heard about FPIES and 7.2% had never heard about it. When presented with clinical anecdotes, 54.1% recognised acute FPIES and 12.9% recognised all chronic FPIES, whereas 10.3% misdiagnosed FPIES as allergic proctocolitis or infantile colic. To diagnose FPIES 55.7% declared to need negative skin prick test or specific-IgE to the trigger food, whereas 56.7% considered necessary a confirmatory oral challenge. Epinephrine was considered the mainstay in treating acute FPIES by 25.8% of respondents. Only 59.8% referred out to an allergist for the long-term reintroduction of the culprit food. Overall, 20.1% reported to care children with FPIES in their practice, with cow's milk formula and fish being the most common triggers; the diagnosis was self-made by the participant in 38.5% of these cases and by an allergist in 48.7%. There is a need for promoting awareness of FPIES to minimise delay in diagnosis and unnecessary diagnostic and therapeutic interventions. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U.

    Typhoid fever is a major health problem in many developing countries and its clinical features are similar to other types of bacterial enterocolitis. Definitive diagnosis by blood culture requires several days and is often unfeasible to perform in developing countries. More efficient and rapid diagnostic methods for typhoid are needed. We compared the pathological changes in the bowel and adjacent tissues of patients having typhoid fever with those having bacterial enterocolitis using ultrasonography. A characteristic of patients with non-typhoidal Salmonella and Campylobacter jejuni enterocolitis was mural thickening of the terminal ileum; only mild mural swelling or no swelling was observed in patients with typhoid fever. Mesenteric lymph nodes in patients with typhoid fever were significantly more enlarged compared to patients with other types of bacterial enterocolitis. Our findings suggest typhoid fever is not fundamentally an enteric disease but rather resembles mesenteric lymphadenopathy and ultrasound is a promising modality for diagnosing typhoid fever in developing countries.

    Full Text Available Systematic reviews of randomised controlled trials report that probiotics reduce the risk of necrotising enterocolitis (NEC in preterm neonates.To determine whether routine probiotic supplementation (RPS to preterm neonates would reduce the incidence of NEC.The incidence of NEC ≥ Stage II and all-cause mortality was compared for an equal period of 24 months 'before' (Epoch 1 and 'after' (Epoch 2 RPS with Bifidobacterium breve M-16V in neonates <34 weeks. Multivariate logistic regression analysis was conducted to adjust for relevant confounders.A total of 1755 neonates (Epoch I vs. II: 835 vs. 920 with comparable gestation and birth weights were admitted. There was a significant reduction in NEC ≥ Stage II: 3% vs. 1%, adjusted odds ratio (aOR = 0.43 (95%CI: 0.21-0.87; 'NEC ≥ Stage II or all-cause mortality': 9% vs. 5%, aOR = 0.53 (95%CI: 0.32-0.88; but not all-cause mortality alone: 7% vs. 4%, aOR = 0.58 (95% CI: 0.31-1.06 in Epoch II. The benefits in neonates <28 weeks did not reach statistical significance: NEC ≥ Stage II: 6% vs. 3%, aOR 0.51 (95%CI: 0.20-1.27, 'NEC ≥ Stage II or all-cause mortality', 21% vs. 14%, aOR = 0.59 (95%CI: 0.29-1.18; all-cause mortality: 17% vs. 11%, aOR = 0.63 (95%CI: 0.28-1.41. There was no probiotic sepsis.RPS with Bifidobacterium breve M-16V was associated with decreased NEC≥ Stage II and 'NEC≥ Stage II or all-cause mortality' in neonates <34 weeks. Large sample size is required to assess the potential benefits of RPS in neonates <28 weeks.

    Enterobacter sakazakii is an emerging pathogen that has been associated with outbreaks of necrotizing enterocolitis (NEC) as well as infant sepsis and meningitis. Our previous studies demonstrated that E. sakazakii induces NEC in a newborn rat model by inducing enterocyte apoptosis. However, the mechanisms responsible for enterocyte apoptosis are not known. Here we demonstrate that E. sakazakii induces significant production of nitric oxide (NO) in rat intestinal epithelial cells (IEC-6) upon infection. The elevated production of NO, which is due to increased expression of inducible NO synthase, is responsible for apoptosis of IEC-6 cells. Notably, pretreatment of IEC-6 cells with Lactobacillus bulgaricus (ATCC 12278) attenuated the upregulation of NO production and thereby protected the cells from E. sakazakii-induced apoptosis. Furthermore, pretreatment with L. bulgaricus promoted the integrity of enterocytes both in vitro and in the infant rat model of NEC, even after challenge with E. sakazakii. Infection of IEC-6 cells with E. sakazakii upregulated several genes related to apoptosis, cytokine production, and various signaling pathways, as demonstrated by rat gene array analysis, and this upregulation was subdued by pretreatment with L. bulgaricus. In agreement with these data, L. bulgaricus pretreatment protected newborn rats infected with E. sakazakii from developing NEC, resulting in improved survival. PMID:19075027

    Vitamin K antagonists are widely used in thromboembolic diseases. Hemorrhagic complications related to drug overdose represent their main side effect. We report a rare side effect, a severe and unexpected type of skin vasculitis - necrotic leg ulcer - induced by vitamin K antagonist. A 63-year-old female with a history of diabetes developed hyperalgesic necrotic ulcerations on the lower limbs one month after starting an acenocoumarol-based treatment for ischemic heart disease. Histological examination revealed lymphocytic vasculitis with fibrinoid necrosis. Etiological explorations searching for vasculitis were negative. In the absence of a precise etiology, drug-induced ulcer was suspected. Low molecular weight heparin was prescribed to replace acenocoumarol. The lesions slowly resolved with topical treatment. The chronological criteria and the negativity of etiological explorations allowed the diagnosis of vitamin K antagonist-induced necrotic skin ulcer. Clinicians should be aware of this rare complication induced by oral anticoagulants because of its practical therapeutic implications. This is the first case of necrotic leg ulcer induced by acenocoumarol corresponding histologically to necrotising lymphocytic vasculitis. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Necrotizing myositis is a rare but life-threatening soft-tissue infection characterized by rapidly spreading inflammation and subsequent necrosis of the affected tissue. The myositis is often caused by toxin-producing, virulent bacteria such as group A β-hemolytic streptococcus and associated with severe systemic toxicity. It is rapidly fatal unless diagnosed promptly and treated aggressively. However, necrotizing myositis is often initially misdiagnosed as a more benign soft-tissue infection as such fulminant, invasive muscle infections are rare with no more than 30 cases reported over the last century. We illustrate the case of a 74-year-old male Caucasian initially presenting with a progressing swelling and gradually oncoming pain of the upper right extremity. Rapidly, livid discolorations of the skin, blisters, hypoesthesia and severe pain resistant to analgesics treatment developed accompanied by disruption of the arterial blood flow. Due to a manifest compartment syndrome the patient was admitted to theater for fasciotomy of the arm. After multiple revision surgeries wound closure was achieved using a pedicled, fasciocutaneous parascapular flap and a free, ipsilateral anterolateral thigh flap. Microbiological analysis revealed group A β-hemolytic streptococcus, histology a bacterial interstitial myositis with necrotic muscular fibers. A high degree of clinical suspicion is necessary to avert potentially disastrous consequences of necrotizing myositis. Timely diagnosis, broad-spectrum antibiotic therapy, and aggressive surgical debridement of affected tissue are keys to the treatment of this serious, often life-threatening infection.

    Full text: Hypoxic tumour cells are radioresistant and are significant contributors to the locoregional recurrences and distant metastases that mark treatment failure. Due to restricted circulatory supply, hypoxic tumor cells frequently become necrotic and thus necrotic areas often lie near hypoxic tumour areas. In this study we investigate the feasibility of binding an alpha-emitting conjugate to necrotic cells located in the proximity of hypoxic, viable tumour cells. Monte Carlo radiation transport simulations were performed to investigate the dose distribution resulting from the thorium 227 (Th227) decay chain in a representative tumour geometry. The Geant4 software toolkit was used to simulate the decay and interactions of the Th227 decay chain. The distribution of Th227 was based on a study by Thomlinson and Gray of human lung cancer histological samples (Thomlinson RH, Gray LH. Br J Cancer 1955; 9:539). The normalized dose distribution obtained with Geant4 from a cylindrical Th227 source in water is illustrated in Fig. I. The relative contribution of the different decay channels is displayed, together with a profile through the centre of the accumulated dose map. The results support the hypothesis that significant α-particle doses will be deposited in the hypoxic tumor tissue immediately surrounding the necrotic core (where the majority of Th227 will be located). As an internal a-particle generator, the Th227-radioimmunoconjugate shows potential as an efficient hypoxic tumour sterilizer.

    Full Text Available Extravasation injury (EI is an iatrogenic condition that occurs preferentially in neonatal and pediatric patients when the injection of fluid substances by intravenous access is required and it accidentally leaks into the adjacent tissues or in spaces outside of vascular compartment. Different types and amount of substances once undergoing extravasation can affect the EI differently [1]. In some instances immediate measures such as saline washout, local antidotes, enzymatic debridement and surgical interventions can be required in order to prevent the occurrence of a growing injury avoiding the progression of the EI to a medical emergency [6]. Here we report an unusual case of a preterm 2-month-old male patient in which the extravasation of balanced electrolyte solution on the upper right arm resulted in the development of full-thickness skin necrosis appearing as the clinical condition of necrotizing fasciitis. The management of necrotic tissue was performed using escharectomy as well as autograft skin under conditions of general anesthesia.

    Objective: Antibiotic therapy is a major risk factor for the development of diarrhea and colitis with varying severity. Often the origin of antibiotic-associated gastrointestinal deterioration remains elusive and no specific infectious agents could be discerned. Patients: We represent three cases of intractable high-volume diarrhea associated with combined antibiotic and steroid therapy in critically ill patients not fitting into established disease entities. Cases presented with severe apoptotic enterocolitis resembling acute intestinal graft-versus-host-disease. Microbiologic workup precluded known enteropathogens, but microbiota analysis revealed a severely depleted gut microbiota with concomitant opportunistic pathogen overgrowth. Interventions: Fecal microbiota transplantation, performed in one patient, was associated with correction of dysbiosis, rapid clinical improvement, and healing of enterocolitis. Conclusions: Our series represents a severe form of antibiotic-associated colitis in critically ill patients signified by microbiota depletion, and reestablishment of a physiologic gastrointestinal microbiota might be beneficial for this condition.

    There are no well-established indications for the surgical management of acute necrotizing pneumonitis in children. This study presents our experience regarding this challenging topic. Between 2002 and 2009, 56 necrotizing pneumonitis patients with empyema were treated surgically. The outcomes were analyzed retrospectively. Computed tomography findings of massive lung necrosis or large cavities involving more than 50% of the involved lobe were deemed to be complicated necrotizing pneumonitis. Patients without the above indications were considered uncomplicated. Thirty-one cases were uncomplicated and 25 were complicated. Operative procedures included 38 decortications (31 uncomplicated and seven complicated), 14 wedge resections, and four lobectomies (complicated only). Preoperatively, patients with complicated necrotizing pneumonia had a higher incidence of pneumothorax (32% vs. 14.3%; p = 0.001), endotracheal intubation (44% vs. 9.7%; p = 0.008), and hemolytic uremic syndrome (20% vs. 3.2%; p = 0.01). These patients also had higher incidences of intraoperative transfusion (68% vs. 9.7%; p = 0.03), major postoperative complications (16% vs. 0%; p = 0.02), reoperations (16% vs. 0%; p = 0.02), and longer postoperative stay (19.8 ± 24.2 days vs. 11.2 ± 5.8 days; p = 0.03). Four complicated patients, who initially had decortications and limited resections, underwent reoperations. Compared with uncomplicated patients, those who underwent decortications and wedge resection required longer postoperative stays (23.6 ± 9.9 days, p < 0.01 and 21.1 ± 30.7 days, p = 0.04, respectively), whereas patients who had lobectomy had a similar duration of recovery (9.0 ± 2.1 days, p = 0.23). All patients improved significantly at follow-up. Children with complicated necrotizing pneumonitis have more preoperative morbidities, more major postoperative complications, and require longer postoperative stays.

    Lemierre syndrome is characterized by a septic thrombophlebitis of the internal jugular vein (IJV) following an oropharyngeal infection. We report a case of Lemierre syndrome that occurred in a context of angina and necrotizing cellulitis of the neck in a 45-year-old patient. The Doppler ultrasound exam of the neck vessels and a neck CT showed an IJV thrombophlebitis. No germ could be isolated in the samples (blood culture, pus). The treatment associated antibiotics, heparin and surgical debridement of the necrotic tissues with extraction of the thrombus after ligation and section of the IJV. The postoperative course was uneventful. Lemierre syndrome is a rare but serious disease. Its low incidence makes him a forgotten disease. It should be systematically suspected in any oropharyngeal infection with the presence of a large painful swelling of the neck. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    A 43-year-old Chinese female had been diagnosed with hyperthyroidism 15 years ago. She was recently administered 150 mg/day propylthiouracil (PTU). After 3 weeks of PTU administration, she developed necrotizing stomatitis and osteonecrosis, most likely due to secondary effects from the PTU treatment. Her neutrophil count was reduced below normal to 0.24×10(9)/L but normalized after withdrawal of PTU therapy. About 1 month after onset, the patient came to our hospital and began to receive intravenous treatments of metronidazole and amoxicillin. Following review of her medical history and a series of clinical and laboratory examinations, the patient was diagnosed with secondary necrotizing gingivostomatitis and osteonecrosis possibly associated with PTU-induced agranulocytosis. One-year after treatment, the patient's oral manifestations remained unchanged. This case demonstrates the need for dental practitioners to more closely monitor oral symptoms in patients with hyperthyroidism treated with antithyroid drugs. Copyright © 2015 Elsevier Inc.

    2010-12-15

    Purpose: This study investigates the features of neutropenic enterocolitis (NE) in adults. Materials and Methods: Chart and radiology report reviews were used to identify neutropenic patients with hematological diseases undergoing chemotherapy, who had CT scans for the clarification of abdominal symptoms between October 2003 and October 2009. Patients with any cause for enteritis other than NE were excluded. The scans were analyzed with respect to imaging features and location. Morphological findings were correlated with clinical data. Results: Thirty-one patients with NE (median age 46 years; range 20 - 75) could be identified. Wall thickening and hyperemia could be found in all bowel segments from jejunum to rectum. The right hemicolon was the most frequent location in 19 patients (61 %). Involvement was generalized in 6 patients (19 %) and segmental in 25 cases (81 %). The longer the duration of neutropenia, the more likely generalized involvement of the bowel was. In 8 patients who underwent CT follow-up, the appearance of bowel segments had completely (n = 5) or partially (n = 3) returned to normal at the latest 14 days after the initial diagnosis. Eight patients (26 %) died 1 - 78 days after NE, 7 of who had previously recovered from NE. Conclusion: CT findings are useful for the diagnosis of NE and should be considered even in the presence of isolated small bowel involvement. The terms NE and typhlitis should thus no longer be used synonymously. (orig.)

    Full Text Available Background: Necrotising enterocolitis (NEC causes a significant life-threatening gastrointestinal system (GIS disease with severe mortality and morbidity, particularly in premature infants. Nitric oxide (NO has many functions in the GIS. Therefore, in the present study, we evaluated the effects of NO in experimentally induced NEC of newborn 1-day-old rats following hypoxia/reoxygenation (HR. Materials and Methods: Thirty Wistar albino rats (weight, 5-8 g were randomly divided into three groups: group 1 (HR, group 2 (HR + nitroglycerine, and group 3 (control. HR was achieved by placing the rat in carbon dioxide (CO2 for five minutes at 22°C, which was followed by five minutes of 100% oxygen. After HR, nitroglycerine was administered for three days at 50 μg/Kg/day. On day 4, the rats were decapitated and the intestines between the duodenum and sigmoid colon were resected and histopathologically examined. Results: The histopathological findings of groups 1 and 2 were characteristic of NEC. Intestinal injury in group 1 was significantly more prevalent than that in group 2 (χ2 = 21.55, P = 0.000. The intestinal injury score in group 3 was significantly lower than that in the other groups (P < 0.05. Conclusions: NO treatment was effective for treating experimentally induced NEC.

    Full Text Available Cow’s milk is the most common cause of food-protein-induced enterocolitis syndrome (FPIES. The aim of this study was to examine the clinical features and treatment outcomes of infants with severe FPIES to cow’s milk. We reviewed all infants ≤12 months of age who were hospitalized and diagnosed with severe FPIES to cow’s milk between 1 January 2011 and 31 August 2014 in a tertiary Children’s Medical Center in China. Patients’ clinical features, feeding patterns, laboratory tests, and treatment outcomes were reviewed. A total of 12 infants met the inclusion criteria. All infants presented with diarrhea, edema, and hypoalbuminemia. Other main clinical manifestations included regurgitation/vomiting, skin rashes, low-grade fever, bloody and/or mucous stools, abdominal distention, and failure to thrive. They had clinical remission with resolution of diarrhea and significant increase of serum albumin after elimination of cow’s milk protein (CMP from the diet. The majority of infants developed tolerance to the CMP challenge test after 12 months of avoidance. In conclusion, we reported the clinical experience of 12 infants with severe FPIES to cow’s milk, which resulted in malnutrition, hypoproteinemia, and failure to thrive. Prompt treatment with CMP-free formula is effective and leads to clinical remission of FPIES in infants.

    Herein we present a case of a 65-year-old woman with enterocolic lymphocytic phlebitis (ELP) who presented with anemic syndrome and in whom severe stenosis of the right flexure of large bowel was detected. The microscopic examination revealed fibrosis of the submucosa and lymphoplasmacytic phlebitis of small veins and venules, whereas arteries were spared. There were 110 IgG4-positive and 160 IgG-positive plasma cells in 1 high-power field, respectively, with corresponding IgG4/IgG ratio of 0.69. The IgG4 serum level was 2.42 g/L. According to the currently proposed criteria, this ELP case is the first that may be diagnosed as definite IgG4-related disease (IgG4-RD). Although based on the sole case description, taken together with a recent review and a case report, we presume that a subset of ELPs is a manifestation of IgG4-RD. © The Author(s) 2014.

    Necrotising enterocolitis (NEC) is associated with inflammatory responses and barrier dysfunction in the gut. In this study, we investigated the effect of Bifidobacterium breve M-16V on factors related to NEC development using an experimental rat model. Caesarean-sectioned rats were given formula milk with or without B. breve M-16V by oral gavage thrice daily, and experimental NEC was induced by exposing the rats to hypoxic conditions. Naturally delivered rats that were reared by their mother were used as healthy controls. The pathological score of NEC and the expression of molecules related to inflammatory responses and the barrier function were assessed in the ileum. B. breve M-16V reduced the pathological scores of NEC and resulted in some improvement in survivability. B. breve M-16V suppressed the increased expression of molecules related to inflammation and barrier function that resulted from NEC induction. B. breve M-16V normalised Toll-like receptor (TRL)4 expression and enhanced TLR2 expression. Our data suggest that B. breve M-16V prevents NEC development by modulating TLR expressions and suppressing inflammatory responses in a rat model.

    Food protein-induced enterocolitis syndrome (FPIES) is an uncommon, non-IgE-mediated food allergy. We recently described a significant increase in fecal eosinophil-derived neurotoxin (EDN) after ingestion of the causative food. However, little is known about the activation status of circulating eosinophils in patients with an acute FPIES reaction. Surface CD69 expression was assessed by flow cytometry on peripheral eosinophils from 5 patients with FPIES before and after ingestion of the causative food. Fecal EDN was measured by enzyme-linked immunosorbent assay. No eosinophil activation was observed before ingestion; however, a significant increase in CD69 expression on eosinophils after an acute FIPES reaction was demonstrated in all of the patients. There was no significant change in absolute eosinophil counts in the peripheral blood. The levels of fecal EDN increased on the day after ingestion of the causative food in all patients. These results suggest that circulating eosinophils as well as eosinophils in the intestinal mucosal tissue are activated in acute FPIES reactions and might be associated with systemic immune events in FPIES. © 2016 S.

    The objective of this retrospective study was to evaluate the outcome of patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy. By searching the radiological, surgical and internal medicine databases, all patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy between 1992 and 2004 were identified. Demographic, laboratory, and clinical data, and details about invasive procedures were collected by reviewing patient charts, radiological and surgical reports. The computed tomography severity index (CTSI) scores were determined by reviewing CT images. Eighteen patients were identified. Median Ranson score on admission was 2. The Acute Physiology and Chronic Health Evaluation (APACHE) II score was median 22. Median CTSI score was 7. Initially all patients were treated with CT-guided drainage placement. Because passive drainage proved not to be effective, subsequent minimally invasive, percutaneous necrosectomy was performed. Eight out of 18 patients recovered fully without the need for surgery. Ten of 18 patients required additional surgical necrosectomy. For one of ten patients, percutaneous necrosectomy allowed postponing surgery by 39 days. Four of ten surgically treated patients died: three from septic multiorgan failure, one from pulmonary embolism. Percutaneous minimally invasive necrosectomy can be regarded as a safe and effective complementary treatment modality in patients with necrotizing pancreatitis. It is suitable for a subset of patients to avoid or delay surgery. (orig.)

The purpose is to examine the effect of a pulpal revascularization procedure on immature necrotic teeth with apical periodontitis. Twenty patients were enrolled for pulp revascularization procedure by root canal disinfection using a triple antibiotic mixture for 1-2 weeks, followed by creating a blood clot, sealing the root canal orifice using white mineral trioxide aggregate and a coronal seal of composite resin. Patients were recalled periodically for up to 24 months. During follow-up, all patients were asymptomatic. Three cases of chronic apical periodontitis showed clinical disappearance of the sinus tract 2 weeks after treatment. Radiography revealed progressive periapical radiolucency resolution within the first 12 months. Within 12-24 months, the treated teeth showed progressive increases in dentinal wall thickness, root length and continued root development. Clinical and radiographic evidence showed successful revascularization treatments of immature necrotic permanent teeth with apical periodontitis. More studies are necessary to understand the underlying mechanisms and to perform histopathology of the pulp space contents after revascularization procedures.

    Full Text Available Necrotizing fasciitis is a rare, life-threatening surgical infection in pregnancy with high rates of morbidity and mortality. A 15-year-old primigravid woman, at 28 weeks of gestation with no significant previous medical history, was admitted to our hospital complaining of severe left lower extremity pain and high fever the last 72 hours. During clinical examination, she had a swollen, erythematous and tender to palpation inflamed skin over the medial aspect of the upper thigh without any evidence of injury. Incision drainage was performed immediately and she received broad spectrum antibiotics. During initial laboratory examinations, diabetes mellitus was diagnosed. There was no clinical improvement over the following days. Magnetic resonance imaging (MRI revealed subcutaneous tissue inflammation and edema of infected tissues confirming the disease entity. Multidisciplinary therapy with immediate aggressive surgical debridement of necrotic tissues, multiple antibiotics, and intensive care monitoring was performed successfully. The patient’s postoperative course was uncomplicated and skin defect was closed with split thickness skin grafting. Our case emphasized the potential immunosuppressive role of pregnancy state in conjunction with diabetes mellitus in the development of severe necrotizing soft tissue infections.

    Full Text Available Wound care in neonates demands special awareness of the anatomical and physiological characteristics of their skin, and the danger of adverse mechanical and toxicological events. Here, we present the case of a full-term neonate born with myelomeningocele. Following the closing surgery on the 3rd day of postuterine life, the operated region became inflamed, the sutures opened and a necrotic discharging ulcer developed. Besides parenteral antibiotic treatment based on the microbiological findings, intelligent hydrofiber dressings were applied to the wound with regard to the special characteristics of wound care in neonates. After 72 days, the ulcer had healed with a small residual scar, and the infant is currently demonstrating normal physical and mental development.

    Probiotic supplementation significantly reduces the risk of necrotising enterocolitis (NEC) and all cause mortality in preterm neonates. Independent quality assessment is important before introducing routine probiotic supplementation in this cohort. To assess product quality, and confirm that Bifidobacterium breve (B. breve) M-16V supplementation will increase fecal B. breve counts without adverse effects. Strain identity (16S rRNA gene sequencing), viability over 2 year shelf-life were confirmed, and microbial contamination of the product was ruled out. In a controlled trial preterm neonates (Gestation breve M-16V (3×109 cfu/day) or placebo (dextrin) supplementation until the corrected age 37 weeks. Stool samples were collected before (S1) and after 3 weeks of supplementation (S2) for studying fecal B. breve levels using quantitative PCR (Primary outcome). Secondary outcomes included total fecal bifidobacteria and NEC≥Stage II. Categorical and continuous outcomes were analysed using Chi-square and Mann-Whitney tests, and McNemar and Wilcoxon signed-rank tests for paired comparisons. A total of 159 neonates (Probiotic: 79, Placebo: 80) were enrolled. Maternal and neonatal demographic characteristics were comparable between the groups. The proportion of neonates with detectable B. breve increased significantly post intervention: Placebo: [S1:2/66 (3%), S2: 25/66 (38%), pbreve counts in both groups were below detection (breve M-16V is a suitable probiotic strain for routine use in preterm neonates.

    The optimal threshold for neonatal platelet transfusions in sick newborns is still uncertain. We report a congenital cytomegalovirus (CMV) infection in a premature neonate with severe thrombocytopenia who subsequently presented with necrotizing enterocolitis and intestinal bleeding. The baby recovered after platelet transfusions were discontinued and the therapy was switched from intravenous ganciclovir to oral valganciclovir. We discuss both measures, speculating on the key role of platelet transfusions.

    Full Text Available Objective: to evaluate the efficiency of hydroxyethyl starch solution (6% refortane, Berlin-Chemie versus fresh frozen plasma used to correct neonatal hypovolemia.Materials and methods. In 12 neonatal infants with hypoco-agulation, hypovolemia was corrected with fresh frozen plasma (10 ml/kg body weight. In 13 neonates, it was corrected with 6% refortane infusion in a dose of 10 ml/kg. Doppler echocardiography was used to study central hemodynamic parameters and Doppler study was employed to examine regional blood flow in the anterior cerebral and renal arteries.Results. Infusion of 6% refortane and fresh frozen plasma at a rate of 10 ml/hour during an hour was found to normalize the parameters of central hemodynamics and regional blood flow.Conclusion. Comparative analysis of the findings suggests that 6% refortane is the drug of choice in correcting neonatal hypovolemia. Fresh frozen plasma should be infused in hemostatic disorders.

    A cohort study of neonatal mortality (N = 106) in white singleton births (N = 14,486) in Utah for January-June 1975 was conducted. Using membership and activity in the Church of Jesus Christ of Latter-day Saints (LDS or Mormon) as a proxy for parental health practices, i.e., tobacco and alcohol abstinence, differential neonatal mortality rates were calculated. The influence of potential confounding factors was evaluated. Low activity LDS members were found to have an excess risk of neonatal death five times greater than high activity LDS, with an upper bound of a two-sided 95% confidence interval of 7.9. The data consistently indicate a lower neonatal mortality rate for active LDS members. Non-LDS were found to have a lower rate than either medium or low activity LDS.

  9. Neonatal pain management

    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    Necrotizing fasciitis is a severe, life-threatening infection.  Serratia marcescens, a Gram-negative bacterium, is an extremely rare cause of necrotizing fasciitis. A case of S. marcescens necrotizing fasciitis is described, and a comprehensive review of the literature (1966-2015) of monomicrobial cases due to this organism performed. We report the first case of S. marcescens necrotizing fasciitis in the setting of calciphylaxis associated with end-stage renal disease.  A comprehensive review of the literature of S. marcescens necrotizing fasciitis is provided to enhance the awareness of this increasingly recognized infection, and to provide a concise summary of risk factors, treatment, and outcome. Our case and review highlight the potential risk factors for S. marcescens necrotizing fasciitis, including underlying renal disease and open wounds, and demonstrate the emergence of this organism as a cause of severe, life-threatening soft tissue infections.

    Full Text Available Efficacy of antenatal corticosteroids before 25 weeks of gestation is unclear.To assess and compare neonatal outcomes following ANC exposure at 22, 23 and 24 weeks of gestation by conducting systematic review and meta- analysis.A systematic review of randomised controlled trials (RCT and non-RCTs reporting on neonatal outcomes after exposure to ANC up to 246 weeks of gestation using the Cochrane systematic review methodology. Databases Pubmed, CINAHL, Embase, Cochrane Central library, and online abstracts of conference proceedings including the Pediatric Academic Society (PAS were searched in Feb 2017. Primary outcome was in-hospital mortality defined as death before discharge during the first admission. Secondary outcomes included severe intraventricular hemorrhage (IVH> grade III and IV/or periventricular leukomalacia (PVL, necrotising enterocolitis (NEC >stage II and chronic lung disease (CLD. Meta-analysis was performed using a random-effects model. The level of evidence (LOE was summarised using the GRADE guidelines.There were no RCTs; 8 high quality non-RCTs were included in the review. Meta-analysis showed reduction in mortality [N = 10109; OR = 0.47(0.39-0.56, p<0.00001; LOE: Moderate] and severe IVH and PVL [N = 5084; OR = 0.71(0.61-0.82, p<0.00001; LOE: Low] after exposure to ANC in neonates born <25 weeks. There was no significant difference in CLD [N = 4649; OR = 1.19(0.85-1.65 p = 0.31; LOE: Low] and NEC [N = 5403; OR = 0.95 (0.76-1.19 p = 0.65; LOE: Low]. Mortality was comparable in neonates born at 22, 23 or 24 weeks.Moderate to low quality evidence indicates that exposure to ANC is associated with reduction in mortality and IVH/or PVL in neonates born before 25 weeks.

    Although food protein-induced enterocolitis syndrome (FPIES) is supposed to be caused by inflammation, the role of cytokines has not yet been clarified. To elucidate the role of cytokines in the development of symptoms and abnormal laboratory findings at an oral food challenge (OFC), changes in serum cytokine levels were analyzed for 6 OFCs in 4 patients with FPIES. The result of OFC was judged positive if any gastrointestinal (GI) symptoms (vomiting, diarrhea, or bloody stool) were induced. Among 11 cytokines profiled, serum levels of interleukin (IL)-2, IL-5, and IL-8 were clearly increased in all 4 positive OFCs in which elevations of the serum level of C-reactive protein (CRP) and peripheral blood neutrophilia were also seen. The level of serum IL-10 also rose in 2 positive OFCs. Remarkable increases in the serum level of interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), IL-6, and IL-12 were observed in a positive OFC where the serum level of CRP rose markedly (6.75 mg/dL). The serum levels of IL-5 were also elevated in 2 negative OFCs. No apparent specific correlations were found between cytokines and GI symptoms. These results suggest that IL-2 and IL-8 are involved in the antigen-specific immune responses in most patients with FPIES. Further studies are needed to elucidate the significance of these cytokine in the pathogenesis of FPIES. Copyright © 2016 Japanese Society of Allergology. Production and hosting by Elsevier B.V.

    To determine the utility of ultrasound in the diagnosis of neutropenic enterocolitis (NEC) in children with cancer or AIDS, and to establish the differential diagnosis with respect to more common causes of acute abdomen. We studied eight patients diagnosed as having NEC over a ten-year period, gathering the clinical data and imaging studied for each. Seven of the children were cancer patients and the remaining child had AIDS. The imaging methods used were plain radiography, B-mode ultrasound and color Doppler ultrasound: in addition, one patient underwent a barium enema. All eight patients presented abdominal pain, predominantly in right iliac fossa, and fever; the neutrophil count was under 100/mm''3. The most common plain abdominal X-ray image was the absence of air in right iliac fossa and dilation of the small bowel loops. One child presented submucosal and subserosal ectopic air colon and cecum, air in the intrahepatic portal system and in peritoneum. Abdominal ultrasound revealed thickening of the cecal mucosa in every case, and color Doppler ultrasound disclosed increased vascularization of the intestinal wall. Six children received medical treatment and two underwent surgery. Three patients died, one a few hours after the surgical procedure and the other two a few days after onset of NEC and initiation of medical treatment. Abdominal ultrasound is the best imaging technique for early diagnosis of NEC and assessment of the response to medical treatment, Moreover, it can be performed at bedside, making it unnecessary to move the patient from his room.

    2008-03-01

    Full Text Available Clostridium perfringens (C. perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen causing necrotic enteritis. C. perfringens only causes necrotic enteritis when it transforms from non-toxin producing type to toxin producing type. The alpha toxin, (phospholipase C is believed to be a key to the occurrence of Clostridial necrotic enteritis (CNE. The best known predisposing factor is mucosal damage, caused by coccidiosis that damages the intestinal lining, making the gut susceptible to infections including C. perfringens. The purpose of this study was to observe the chicken performance in experimental CNE and field cases of CNE. Diagnosis of CNE were made by latex agglutination test, isolation and identification of the agent. Pathological and histopathological changes were also observed. Experimentally, NE could be reproduced when Eimeria sp and C. perfringens spores are inoculated in chicken. Signs of an NE are wet litter and diarrhea, and an increase in mortality is not often obvious. The depression of growth rate and feed efficiency of chicken become noticeable by week 5 because of damage to the intestine and the subsequent reduction in digestion and absorption of food. Subclinical form of CNE was also frequently found in the field, leading to significant decreases in performance. Chicken gut samples examinations revealed that subclinical form of CNE causes damage to the intestinal mucosa caused by C. perfringens leads to decreased digestion and absorption, increased feed conversion ratio and reduced weight gain. Dual infection with C. perfringens and Eimeria sp. was frequently found in field. The results of these studies provide evidence for C. perfringens as a causative bacteria for growth depression.

    2014-09-01

    Orbital injury secondary to petroleum-based products is rare. We report the first case, to our knowledge, of a combined compressed air and chemical orbital injury, which mimicked necrotizing fasciitis. A 58-year-old man was repairing his motorcycle engine when a piston inadvertently fired, discharging compressed air and petroleum-based carburetor cleaner into his left eye. He developed surgical emphysema, skin necrosis, and a chemical cellulitis, causing an orbital compartment syndrome. He was treated initially with antibiotics and subsequently with intravenous steroid and orbital decompression surgery. There was almost complete recovery by 4 weeks postsurgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Petroleum-based products can cause severe skin irritation and necrosis. Compressed air injury can cause surgical emphysema. When these two mechanisms of injury are combined, the resulting orbitopathy and skin necrosis can mimic necrotizing fasciitis and cause diagnostic confusion. A favorable outcome is achievable with aggressive timely management. Copyright © 2014 Elsevier Inc. All rights reserved.

  8. Treatment of Necrotic Calcified Tooth Using Intentional Replantation Procedure

    2014-01-01

    Full Text Available Introduction. If the teeth are impacted by a chronic irritant, the pulp space possibly will undergo calcific changes that may impede access opening during root canal treatment. In such cases that conventional endodontic treatment is impossible or impractical, intentional replantation may be considered as a last solution to preserve the tooth. Methods. After failing to perform conventional root canal therapy for a necrotic calcified right mandibular second premolar, the tooth was gently extracted. The root apex was resected and the root end cavity was prepared and filled with calcium enriched mixture (CEM cement. Then, the extracted tooth was replanted in its original position. Results. After a year the tooth was asymptomatic, and the size of periapical radiolucency was remarkably reduced and no clinical sign of ankylosis was observed. Conclusion. Intentional replantation of the necrotic calcified teeth could be considered as an alternative to teeth extraction, especially for the single-rooted teeth and when nonsurgical and surgical endodontic procedures seem impossible.

    Full Text Available This report describes a case of necrotizing fasciitis presenting with septic shock due to an Aeromonas infection. The patient cut his foot while mowing the lawn and then spent time in a pool with black mold. He began feeling ill and developed swelling and a quarter-sized black area on his right lower extremity. Despite being hemodynamically unstable with systolic blood pressure in the low 70s, the patient was transferred to our facility from outside hospital 100 miles away. Upon arriving to facility, the patient appeared to be septic and the infected area of skin had grown. Irrigation and debridement were performed and appropriate antibiotic therapy was given; however, the patient subsequently died on hospital day 8. On review of the literature, cases of necrotizing fasciitis due to Aeromonas infection have been treated successfully with the aforementioned therapy; however, there is high mortality associated with these infections, many times related to a delayed diagnosis. Our patient also had multiple poor prognostic factors including hepatic dysfunction and immunosuppression.

    Pagès, P-B; Bernard, A

    2012-04-01

    Lung abscesses and necrotizing pneumonia are rare complications of community-acquired pneumonia since the advent of antibiotics. Their management leans first of all on the antibiotic treatment adapted on the informed germs. However, in 11 to 20% of the cases of lung abscesses, this treatment is insufficient, and drainage, either endoscopic or percutaneous, must be envisaged. In first intention, we shall go to less invasive techniques: endoscopic or percutaneous radio-controlled. In case of failure of these techniques, a percutaneous surgical drainage by minithoracotomy will be performed. In the necrotizing pneumonia, because of the joint obstruction of the bronchus and blood vessels corresponding to a lung segment, the systemic antibiotic treatment will be poor effective. In case of failure of this one we shall propose, a percutaneous surgical drainage, especially if the necrosis limits itself to a single lobe. The surgical treatment will be reserved: in the failures of the strategy of surgical drainage, in the necroses extending in several lobes. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Necrotic angiodermatitis is a variety of leg ulcer, characterized by very painful and rapidly spreading lesions. Healing takes time, a mean of 4 to 11 months. Current treatment is difficult and rarely satisfactory. Only early skin grafts lead to rapid sedation of pain and stop the lesion from extending. However, this technique, performed during a progressive phase, enhances the risk of losing a certain number of grafts. We wanted to confirm the efficacy of local auto-haemo-therapy proposed in 2 non-controlled studies. Eleven patients with necrotic angiodermatitis were included in our non-controlled prospective study. The topical hemotherapy was applied three times a week for one month, with initial hospitalization for 15 days. The criteria of assessment were: evolution of pain, surface of the ulcer, colorimetric scale and the date of disappearance of the purple halo. Ten patients were relieved by the treatment, with progressive withdrawal of the analgesics. The progression of the lesion had stopped and the purple halo had disappeared in general by D6 (range: 2 to 21 days). The percentage of granulation tissue with regard to the surface of the ulcer was of 45.4 p. 100 on D0, 80 p. 100 on D14 and 85 p. 100 on D28. Topical hemotherapy applied during the initial phase of treatment would reduce the pain and prepare the lesion for a secondary skin graft.

    Bovine necrotic vulvovaginitis (BNVV) is a severe and potentially fatal disease of post-partum cows that emerged in Israel after large dairy herds were merged. While post-partum cows are commonly affected by mild vulvovaginitis (BVV), in BNVV these benign mucosal abrasions develop into progressive deep necrotic lesions leading to sepsis and death if untreated. The etiology of BNVV is still unknown and a single pathogenic agent has not been found. We hypothesized that BNVV is a polymicrobial disease where the normally benign vaginal microbiome is remodeled and affects the local immune response. To this end, we compared the histopathological changes and the microbial communities using 16S rDNA metagenetic technique in biopsies taken from vaginal lesions in post-partum cows affected by BVV and BNVV. The hallmark of BNVV was the formation of complex polymicrobial communities in the submucosal fascia and abrogation of neutrophil recruitment in these lesions. Additionally, there was a marked difference in the composition of bacterial communities in the BNVV lesions in comparison to the benign BVV lesions. This difference was characterized by the abundance of Bacteroidetes and lower total community membership in BNVV. Indicator taxa for BNVV were Parvimonas, Porphyromonas, unclassified Veillonellaceae, Mycoplasma and Bacteroidetes, whereas unclassified Clostridiales was an indicator for BVV. The results support a polymicrobial etiology for BNVV. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Objectives. The aim of this study was to characterize the lesions of necrotizing gingivitis (NG and necrotizing periodontitis (NP with regard to extent and severity, and to correlate these parameters with the host HIV serostatus, CD4+ T-cell count, neutrophil count, age, and gender. Methods. Eighty-four consecutive patients, 39 black females and 45 black males aged 20–46 years, diagnosed with NG/NP were recruited to the study over a period of two years. Results. For both HIV-seropositive and -seronegative patients, the mandibular anterior gingiva was most frequently affected; 74% had NG/NP affecting ≥5 gingival tooth sites. Ninety percent of all patients had a mean severity of ≤4 mm. There was no statistically significant association between either extent or severity of NG/NP and HIV serostatus, CD4+ T-cell count, neutrophil count, age, or gender. The difference between the number of HIV-seropositive patients with NG/NP who had CD4+ T-cell counts ≤200 cells/mm3 and those who had CD4+ T cell counts of 201–499 cells/mm3 was not statistically significant. Conclusion. The clinical signs of NG/NP are similar in HIV-seropositive and -seronegative patients, and are not related to CD4+ T-cell count, to neutrophil count, to gender, or to age.

    Full Text Available Acinar necrosis is the basic microscopic sign of acute necrotizing pancreatitis (ANP. Microcirculation disorder is one of the major factors in the pathogenesis and morphogenesis of ANP besides free radicals and damage of enzymatic origin. This study is dedicated to the description of microscopic changes in the pancreatic stroma in ANP, which leads to destruction of the exocrine pancreas with a putative mechanism of endocrine function preservation. This study has been carried out on histological samples of pancreas from 224 patients with ANP. Histological staining was performed with hematoxylin-eosin (H&E, Masson, Gomori methods, and PAS. Microscopy was performed with magnifications of 40×, 100×, and 400×. Vascular endothelial desquamation, stasis, and sludge are typical changes in microcirculation observed in early stages of ANP. Initially, parietal circular intravascular microthrombosis accompanied by endothelial desquamation as early as stromal swelling occurs with no detectable necrosis. Residual stroma appears between areas of necrosis and intact pancreatic tissue. Mucoid swelling is first seen in the perivascular spaces extending to the parenchyma and changing into fibrinoid imbibition causing further necrosis. Reticulin argyrophilic backbone surrounding the pancreatic acini and small ducts decompose. Pancreatic structures, which may be preserved in necrotic tissue, include nerves, major ducts, and Langerhans islets.

    Subacute necrotizing myelopathy(SNM) is a rare non-tumorous disease of spinal cord characterized by subacute clinical course of progressive neurological deterioration. We report MR findings of a patient with pathologically proved SNM. 1 case of pathologically proved subacute necrotizing myelopathy. The patients was a 56-year-old man with progressive motor weakness and sensory loss of the lower extremities, and urinary and fecal incontinence for 11 months. Spine MRI revealed diffuse enlargement of the thoracic spinal cord from T2 to T7 level. Signal intensity of the expanded spinal cord was isointense relative to normal cord on T1-weighted image and hyperintense on proton-density and T2-weighted images. On contrast enhanced T1-weighted image, there was diffuse homogeneous enhancement in the expanded cord lesion. MR demonstration of stable persistence of spinal cord lesion or atrophy over months or years with clinical findings of gradual progressive neurologic deterioration may be helpful in the diagnosis of SNM

    This study was conducted to determine the effect of age at diagnosis and length of ganglionated bowel resected on postoperative Hirschsprung-associated enterocolitis (HAEC). Children who underwent endorectal pull-through (ERPT) between January 1993 and December 2004 were retrospectively reviewed. t Test, analysis of variance, Kaplan-Meier, and Cox's proportional hazards analyses were performed. Fifty-two children with Hirschsprung disease (median age, 25 days; range, 2 days-16 years) were included. Nineteen (37%) had admissions for HAEC. Proportional hazards regression showed that HAEC admissions decreased by 30% with each doubling of age at diagnosis (P = .03) and increased 9-fold when postoperative stricture was present (P 5 cm]). No significant difference in the number of HAEC admissions during initial 2 years post-ERPT was seen between groups A (n = 18) and B (n = 18). The study had a power of 0.8 to detect a difference of 1 admission over 2 years. Children diagnosed with Hirschsprung disease at younger ages are at a greater risk for postoperative enterocolitis. Excising a longer margin of ganglionated bowel (>5 cm) does not seem to be beneficial in decreasing HAEC admissions.

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    Neonatal lupus erythematosus (NLE) is an uncommon disease of the neonate. It is believed to be caused by the transplacental passage of maternal autoantibodies to the ribonucleoproteins (Ro\\/SSA, La\\/SSB or rarely U RNP) as these are almost invariably present in NLE sera. The most common clinical manifestations include cutaneous lupus lesions and congenital complete heart block. Hepatobiliary and haematologic abnormalities are reported less frequently. We describe a patient with cutaneous NLE to illustrate and raise awareness of the characteristic annular eruption of this condition. We also emphasize the need for thorough investigation for concomitant organ involvement and for maternal education regarding risk in future pregnancies.

    Food protein-induced enterocolitis syndrome (FPIES) is a particular non-IgE-mediated food allergy, manifested by profuse and repetitive vomiting with hypotonia and lethargy in its acute form. A retrospective descriptive single-center study was conducted. Subjects included in this study were children with acute FPIES who consulted the allergy outpatient clinic of the Nancy Regional University Hospital between November 2013 and June 2016. Among the 14 patients (eight boys and six girls), nine had a history of atopy: a family history for six (42.8%) and a personal history for five (35.7%). Three had chronic FPIES turning into acute FPIES. Cow milk was the most common triggering food (50%), followed by fish (21.4%), mussels (14.3%), wheat (7.1%), egg (7.1%), and poultry (7.1%). The average time from ingestion to symptom onset was 90minutes. The symptoms were typical and diarrhea was not systematic (42.8%). Six children were hospitalized, some of them several times, including once in intensive care for one patient. The treatments established were, in order of frequency: oral or intravenous rehydration, corticosteroids, antihistamines, and antiemetics. Diagnosis time was 7.6 months on average; it was significantly shorter for milk than for solid foods (1.4 vs. 12 months, P-value=0.02), on average after two episodes. Another diagnosis than FPIES was raised at first for five patients (acute gastroenteritis, gastroesophageal reflux, and bowel obstruction caused by bowel volvulus). Allergy tests were initially negative. Two chronic FPIES cases (one milk FPIES and one milk and wheat FPIES) developed an acute FPIES to another food (fish and mussels); one patient changed from an acute fish FPIES to an IgE-mediated phenotype over time. FPIES resolved for four patients: three milk FPIES, on average 15.7 months after the first reaction, and one wheat FPIES, 2.5 years after the first reaction. A child with a white fish FPIES was able to introduce salmon and tuna. FPIES is a

    Ischemic osteonecrosis of the femoral head (IOFH) can lead to excessive resorption of the trabecular bone and collapse of the femoral head as a structure. A well-known mineral component to trabecular bone is hydroxyapatite, which can be present in many forms due to ionic substitution, thus altering chemical composition. Unfortunately, very little is known about the chemical changes to bone apatite following IOFH. We hypothesized that the apatite composition changes in necrotic bone possibly contribute to increased osteoclast resorption and structural collapse of the femoral head. The purpose of this study was to assess the macroscopic and local phosphate composition of actively resorbed necrotic trabecular bone to isolate differences between areas of increased osteoclast resorption and normal bone formation. A piglet model of IOFH was used. Scanning electron microscopy (SEM), histology, X-ray absorbance near edge structure (XANES), and Raman spectroscopy were performed on femoral heads to characterize normal and necrotic trabecular bone. Backscattered SEM, micro-computed tomography and histology showed deformity and active resorption of necrotic bone compared to normal. XANES and Raman spectroscopy obtained from actively resorbed necrotic bone and normal bone showed increased carbonate-to-phosphate content in the necrotic bone. The changes in the apatite composition due to carbonate substitution may play a role in the increased resorption of necrotic bone due to its increase in solubility. Indeed, a better understanding of the apatite composition of necrotic bone could shed light on osteoclast activity and potentially improve therapeutic treatments that target excessive resorption of bone.

    Improving vaccine potency in the induction of a strong cell-mediated cytotoxicity can enhance the efficacy of vaccines. Necrotic cells and the supernatant of necrotic tumor cells are attractive adjuvants, on account of their ability to recruit antigen-presenting cells to the site of antigen synthesis as well as its ability to stimulate the maturation of dendritic cells. To evaluate the utility of supernatant of necrotic tumor cells as a DNA vaccine adjuvant in a murine model. The supernatant of EL4 necrotic cells was co-administered with a DNA vaccine expressing the glycoprotein B of Herpes simplex virus-1 as an antigen model under the control of Cytomegalovirus promoter. C57BL/6 mice were vaccinated three times at two weeks intervals with glycoprotein B DNA vaccine and supernatant of necrotic EL4 cells. Five days after the last immunization, cell cytotoxicity, IFN-γ and IL-4 were evaluated. The obtained data showed that the production of IFN-γ from the splenocytes after antigenic stimulation in the presence of the supernatant of necrotic EL4 cells was significantly higher than the other groups (pEL4 cells in the mice immunized with DNA vaccine and supernatant of necrotic EL4 cells comparing to the other groups (p<0.001). The supernatant of necrotic cells contains adjuvant properties that can be considered as a candidate for tumor vaccination.

    Full Text Available Reactive arthritis (ReA is an inflammatory condition of the joints that arises following an infection. Salmonella enterocolitis is one of the most common infections leading to ReA. Although the pathogenesis remains unclear, it is known that IL-17 plays a pivotal role in the development of ReA. IL-17-producers cells are mainly Th17, iNKT, and γδT lymphocytes. It is known that iNKT cells regulate the development of Th17 lineage. Whether iNKT cells also regulate γδT lymphocytes differentiation is unknown. We found that iNKT cells play a protective role in ReA. BALB/c Jα18−/− mice suffered a severe Salmonella enterocolitis, a 3.5-fold increase in IL-17 expression and aggravated inflammation of the synovial membrane. On the other hand, activation of iNKT cells with α-GalCer abrogated IL-17 response to Salmonella enterocolitis and prevented intestinal and joint tissue damage. Moreover, the anti-inflammatory effect of α-GalCer was related to a drop in the proportion of IL-17-producing γδT lymphocytes (IL17-γδTcells rather than to a decrease in Th17 cells. In summary, we here show that iNKT cells play a protective role against Salmonella-enterocolitis and Salmonella-induced ReA by downregulating IL17-γδTcells.

    Full Text Available Introduction: About 0.1% of the population suffers from necrotizing ulcerative gingivitis, a disease of rapid progression and acute manifestation, which may progress to necrotizing ulcerative periodontitis and eventually to bone sequestration and loss of gingival tissue. Case report: A 21-year-old female patient undergoing orthodontic treatment for six months, diagnosed with necrotizing ulcerative gingivitis due to acute pain in the gingival tissue, spontaneous bleeding, halitosis and abundant plaque. The treatment was conservative and effective, obtaining total remission of the lesion after seven days and three months of postoperative follow-up. Conclusion: Today there are no epidemiological or clinical reports that support the relationship of necrotizing ulcerative gingivitis and orthodontic treatment. Prevention is critical to the success of the treatment, which is why the dentist should recognize the clinical features of necrotizing ulcerative gingivitis to raise awareness of its risks in the orthodontic patient.

    Yuqing Li

    Full Text Available Hirschsprung-associated enterocolitis (HAEC is a life-threatening complication of Hirschsprung's disease (HD. Although the pathological mechanisms are still unclear, studies have shown that HAEC has a close relationship with the disturbance of intestinal microbiota. This study aimed to investigate the characteristics of the intestinal microbiome of HD patients with or without enterocolitis. During routine or emergency surgery, we collected 35 intestinal content samples from five patients with HAEC and eight HD patients, including three HD patients with a history of enterocolitis who were in a HAEC remission (HAEC-R phase. Using Illumina-MiSeq high-throughput sequencing, we sequenced the V4 region of bacterial 16S rRNA, and operational taxonomic units (OTUs were defined by 97% sequence similarity. Principal coordinate analysis (PCoA of weighted UniFrac distances was performed to evaluate the diversity of each intestinal microbiome sample. The microbiota differed significantly between the HD patients (characterized by the prevalence of Bacteroidetes and HAEC patients (characterized by the prevalence of Proteobacteria, while the microbiota of the HAEC-R patients was more similar to that of the HAEC patients. We also observed that the specimens from different intestinal sites of each HD patient differed significantly, while the specimens from different intestinal sites of each HAEC and HAEC-R patient were more similar. In conclusion, the microbiome pattern of the HAEC-R patients was more similar to that of the HAEC patients than to that of the HD patients. The HD patients had a relatively distinct, more stable community than the HAEC and HAEC-R patients, suggesting that enterocolitis may either be caused by or result in a disruption of the patient's uniquely adapted intestinal flora. The intestinal microbiota associated with enterocolitis may persist following symptom resolution and can be implicated in the symptom recurrence.

  17. Characterization of Bacterial and Fungal Microbiome in Children with Hirschsprung Disease with and without a History of Enterocolitis: A Multicenter Study.

    Directory of Open Access Journals (Sweden)

    Philip K Frykman

    Full Text Available Development of potentially life-threatening enterocolitis is the most frequent complication in children with Hirschsprung disease (HSCR, even after definitive corrective surgery. Intestinal microbiota likely contribute to the etiology of enterocolitis, so the aim of this study was to compare the fecal bacterial and fungal communities of children who developed Hirschsprung-associated enterocolitis (HAEC with HSCR patients who had never had enterocolitis. Eighteen Hirschsprung patients who had completed definitive surgery were enrolled: 9 had a history of HAEC and 9 did not. Fecal DNA was isolated and 16S and ITS-1 regions sequenced using Next Generation Sequencing and data analysis for species identification. The HAEC group bacterial composition showed a modest reduction in Firmicutes and Verrucomicrobia with increased Bacteroidetes and Proteobacteria compared with the HSCR group. In contrast, the fecal fungi composition of the HAEC group showed marked reduction in diversity with increased Candida sp., and reduced Malassezia and Saccharomyces sp. compared with the HSCR group. The most striking finding within the HAEC group is that the Candida genus segregated into "high burden" patients with 97.8% C. albicans and 2.2% C. tropicalis compared with "low burden" patients 26.8% C. albicans and 73% C. tropicalis. Interestingly even the low burden HAEC group had altered Candida community structure with just two species compared to more diverse Candida populations in the HSCR patients. This is the first study to identify Candida sp. as potentially playing a role in HAEC either as expanded commensal species as a consequence of enterocolitis (or treatment, or possibly as pathobioants contributing to the pathogenesis of HAEC. These findings suggest a dysbiosis in the gut microbial ecosystem of HAEC patients, such that there may be dominance of fungi and bacteria predisposing patients to development of HAEC.

    Necrotizing fasciitis (NF) is an uncommon, rapidly progressive, and potentially fatal infection of the superficial fascia and subcutaneous tissue. NF caused by an enterocutaneous fistula has special clinical characters compared with other types of NF. NF caused by enterocutaneous fistula may have more rapid progress and more severe consequences because of multiple germs infection and corrosion by digestive juices. We treated three cases of NF caused by postoperative enterocutaneous fistula since Jan 2007. We followed empirically the principle of eliminating anaerobic conditions of infection, bypassing or draining digestive juice from the fistula and changing dressings with moist exposed burn therapy impregnated with zinc/silver acetate. These three cases were eventually cured by debridement, antibiotics and wound management.

    Full Text Available A survey of Prunus necrotic ringspot virus (PNRSV incidence in Jordan stone-fruit growing areas was conducted during 2000–2002. A total of 2552 samples were collected from 72 commercial orchards, a mother block, 15 nurseries, and a varietal collection. A total of 208 almond, 451 apricot, 149 cherry, 250 nectarine, 1016 peach, and 478 plum trees were tested individually for PNRSV by the double-antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA. Around 15% of tested samples were infected with PNRSV. The virus incidence in almond, nectarine, plum, peach, cherry, and apricot was 24, 16, 16, 14, 13, and 10% of tested trees respectively. The level of viral infection was highest in the mother block (19%, and lowest in the samples from the nurseries (10%.

    Prunus necrotic ringspot virus (PNRSV) occurs as numerous strains or isolates that vary widely in their pathogenic, biophysical and serological properties. Prior attempts to distinguish pathotypes based upon physical properties have not been successful; our approach was to examine the molecular properties that may distinguish these isolates. The nucleic acid sequence was determined from 1.65 kbp RT-PCR products derived from RNA 3 of seven distinct isolates of PNRSV that differ serologically and in pathology on sweet cherry. Sequence comparisons of ORF 3a (putative movement protein) and ORF 3b (coat protein) revealed single nucleotide and amino acid differences with strong correlations to serology and symptom types (pathotypes). Sequence differences between serotypes and pathotypes were also reflected in the overall phylogenetic relationships between the isolates.

    Full Text Available There has been much media attention in the past few years to the condition dubbed 'flesh-eating disease', which refers, primarily, to a form of invasive group A beta hemolytic streptococcal (GABHS infection that leads to fascia and muscle necrosis. In 1999, the Canadian Paediatric Society issued a statement on the state of knowledge and management of children, and close contacts of persons with all-invasive GABHS disease (1. The present note is intended to deal specifically with necrotizing fasciitis (NF by providing an update on the limited current state of knowledge, diagnosis and management. Surveillance to establish actual national rates and epidemiology of NF through the Canadian Paediatric Society is proposed.

  3. Experimental reproduction of necrotic enteritis in chickens: a review.

    This review discusses key factors important in successful experimental reproduction of necrotic enteritis (NE) in chickens, and how these factors can be adjusted to affect the severity of the lesions induced. The critical bacterial factor is the need to use virulent, netB-positive, strains of Clostridium perfringens; disease severity can be enhanced by using netB-positive C. perfringens strains that are also tpeL-positive, by the use of young rather than old broth cultures, and by the number of days of inoculation and the number of bacteria used. Use of cereals rich in non-starch polysaccharides can enhance disease, as does use of animal proteins. Administration of coccidia, including coccidial vaccines, combined with netB-positive C. perfringens, increases the severity of experimentally-induced NE. Dietary manipulation may be less important in coccidia-based models since the latter are so effective. Disease scoring systems and welfare considerations are discussed.

    This case report describes the clinical and postmortem findings in a 2.5-year-old goat with necrotizing granulomatous pneumonia. The goat was referred to our clinic because of swelling of the head and neck, which was unresponsive to treatment, dysphagia, and deterioration in general condition. Thoracic radiographs showed two soft tissue densities, about 10 cm in diameter, in the left caudodorsal lung. The goat was euthanized and a necropsy was carried out. The two lesions in the left caudodorsal lung were round, firm and clearly demarcated from the surrounding lung tissue. They contained purulent material and compromised about 70 % of the diaphragmatic lung lobe. Histological examination of the lesions revealed a dense network of hyphae characteristic of Mucorales spp

    Acute necrotizing encephalopathy of childhood (ANE) is characterized by multiple, symmetrical brain lesions affecting the bilateral thalami, putamina and cerebral white matter, which often show a concentric structure on CT and MRI. To reveal the pathological substrate of this finding, comparison was made between CT and necropsy findings of three fatal cases of ANE. Cranial CT demonstrated a concentric structure of the thalamocerebral lesions in one patient who died 3.5 days after the onset of encephalopathy, but not in the other two patients who died within 30 h. Neuropathological examination of postmortem brains revealed laminar changes of vascular and parenchymal pathology in all the cases. Excessive permeability of blood vessels and resultant vasogenic edema became more prominent with increasing depth from the cerebral surface. The deep portion of the lesions showed severe perivascular hemorrhage, accounting for the central high density on the CT images of one patient. (orig.)

    Full Text Available Necrotizing fasciitis is a severe, rare, potentially lethal soft tissue infection that develops in the scrotum and perineum, the abdominal wall or the extremities. The infection progresses rapidly, and septic shock may ensue; hence, the mortality rate is high (median mortality 32.2%. Prognosis becomes poorer in the presence of co-morbidities, such as diabetes mellitus, immunosuppression, chronic alcohol disease, chronic renal failure and liver cirrhosis. Necrotizing fasciitis is classified into four types, depending on microbiological findings. Most cases are polymicrobial, classed as type I. The clinical status of the patient varies from erythema, swelling and tenderness in the early stage to skin ischemia with blisters and bullae in the advanced stage of infection. In its fulminant form, the patient is critically ill with signs and symptoms of severe septic shock and multiple organ dysfunction. The clinical condition is the most important clue for diagnosis. However, in equivocal cases, the diagnosis and severity of the infection can be secured with laboratory-based scoring systems, such as the LRINEC score or FGSI score, especially in regard to Fournier’s gangrene. Computed tomography or ultrasonography can be helpful, but definitive diagnosis is attained by exploratory surgery at the infected sites.Management of the infection begins with broad spectrum antibiotics, but early and aggressive drainage and meticulous debridement constitute the mainstay of treatment. Postoperative management of the surgical wound is also important for the patient’s survival, along with proper nutrition. The vacuum-assisted closure system has proved to be helpful in wound management, with its combined benefits of continuous cleansing of the wound and the formation of granulation tissue.

    Here we describe the clinicopathological course of a 20-year-old female patient with enterocolic lymphocytic phlebitis (ELP) of the appendix vermiformis and cecal pole with increase of IgG4-positive plasma cells. The patient presented with acute abdomen, suspicious of acute appendicitis. Diagnostic laparoscopy showed tumefaction of the cecal pole and appendix vermiformis. Histologic examination revealed mural thickening and a dense lymphoplasmocytic, partly obliterative infiltrate of the veins with sparing of the arteries, diagnostic of ELP. In addition, we found an elevated number of IgG4-positive plasma cells blended in with the lymphocytes. The IgG4-to-IgG ratio accounted for >40 %. This case meets the histopathological criteria requested for IgG4-related disease (IgG4-RD) and thus opens the possibility that ELP might be part of the IgG4-RD spectrum.

  9. Experience of the successful treatment with canakinumab of a patient with NLPC4-associated autoinflammatory syndrome with enterocolitis

    Full Text Available The article shows the observation of rare NLPC4-associated autoinflammatory syndrome with enterocolitis and familial cold urticaria. Diagnosis is confirmed molecularly-genetically: previously not described mutation c.928C>T in the heterozygous state in NLRC4 gene is discovered by a method of the new generation sequencing. The use of a monoclonal antibody to the interleukin 1 canakinumab provided complete relief of fever and skin and intestinal symptoms in just 1 week of treatment. Later the signs of inflammation have disappeared completely; the patient’s quality of life improved and life-threatening complications were prevented. The above example demonstrates the high clinical efficacy of canakinumab in the patient with NLRC4-associated autoinflammatory syndrome and suggests promising therapeutic use of interleukin 1 blockers in such patients. There were no adverse events during canakinumab therapy.

    Full Text Available Necrotizing fasciitis is a rare and life-threatening soft tissue infection that spreads rapidly and involves the skin, subcutaneous tissue, fascia, and muscle layer. The treatment is possible by initiating appropriate antibiotherapy for the clinically suspected cause and by performing surgical intervention quickly and aggressively. However, it should be known that necrotizing fasciitis is a disease that is difficult to manage despite all interventions, effective treatment protocols, and patient care. This article presents the case of a 60-year-old patient with diabetes mellitus who died of toxic shock syndrome with fulminant necrotizing fasciitis caused by Streptococcus agalactiae.

    We report the case of a 74-year-old female who developed a necrotizing sclerokeratitis affecting her left eye after uncomplicated cataract surgery. She had no previous history of systemic autoimmune disease. Histopathology of the lesion revealed necrotic granulomatosis with an increased number of plasma cells. Surgically induced necrotizing sclerokeratitis (SINS) is a serious entity which requires prompt and aggressive therapy to prevent its potential devastating ocular consequences. Conjunctival resection and amniotic membrane grafting may be necessary to temporarily interrupt local immunologic events in severe cases. However, associated systemic immunomodulatory therapy seems to be mandatory (Arch Soc Esp Oftalmol 2009; 84: 577-580).

    Full Text Available Necrotizing fasciitis is a life-threatening, soft tissue infection and an early diagnosis is needed to permit a prompt surgical and medical intervention. Due to the high fatal potential of the disease complications, the radiologist should distinguish necrotizing fasciitis from the most common soft tissue infections, in order to permit a prompt surgical and medical treatment. We present a case of a wide necrotizing fasciitis who presented at our emergency department and we also provide the basic tools, through a review of the literature, for the general radiologist to distinguish, with computed tomography and magnetic resonance imaging, necrotizing fasciitis from the most common infections that could present during our routine practice.

    Full Text Available Abstract Introduction Necrotizing fasciitis is a rare and life-threatening rapidly progressive soft tissue infection. A fulminant case could involve muscle and bone. Necrotizing fasciitis after corticosteroid therapy and intramuscular injection of non-steroidal anti-inflammatory drugs has been reported. We present a case of fulminant necrotizing fasciitis occurring in a patient who used a herbal concoction to treat a chronic leg ulcer. Case presentation A 20-year-old Ibo woman from Nigeria presented with a three-year history of recurrent chronic ulcer of the right leg. She started applying a herbal concoction to dress the wound two weeks prior to presentation. This resulted in rapidly progressive soft tissue necrosis that spread from the soft tissue to the bone, despite aggressive emergency debridement. As a result she underwent above-knee amputation. Conclusion The herbal concoction used is toxic, and can initiate and exacerbate necrotizing fasciitis. Its use for wound dressing should be discouraged.
