Abstract
BACKGROUND AND OBJECTIVE Patent ductus arteriosus (PDA) ligation has been variably associated with neonatal morbidities and neurodevelopmental impairment (NDI). The objective was to systematically review and meta-analyze the impact of PDA ligation in preterm infants at <32 weeks' gestation on the risk of mortality, severe neonatal morbidities, and NDI in early childhood. METHODS Medline, Embase, Cochrane Central Register of Controlled Trials, Education Resources Information Centre (ERIC), Cumulative Index to Nursing and Allied Health (CINAHL), PsycINFO, and the Dissertation database were searched (1947 through August 2013). Risk of bias was assessed by using the Newcastle-Ottawa Scale and the Cochrane Risk of Bias tool. Meta-analyses were performed by using a random-effects model. Unadjusted and adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were pooled when appropriate. RESULTS Thirty-nine cohort studies and 1 randomized controlled trial were included. Nearly all cohort studies had at least moderate risk of bias mainly due to failure to adjust for survival bias and important postnatal preligation confounders such as ventilator dependence, intraventricular hemorrhage, and sepsis. Compared with medical treatment, surgical ligation was associated with increases in NDI (aOR: 1.54; 95% CI: 1.01-2.33), chronic lung disease (aOR: 2.51; 95% CI: 1.98-3.18), and severe retinopathy of prematurity (aOR: 2.23; 95% CI: 1.62-3.08) but with a reduction in mortality (aOR: 0.54; 95% CI: 0.38-0.77). There was no difference in the composite outcome of death or NDI in early childhood (aOR: 0.95; 95% CI: 0.58-1.57). CONCLUSIONS Surgical ligation of PDA is associated with reduced mortality, but surviving infants are at increased risk of NDI. However, there is a lack of studies addressing survival bias and confounding by indication.

Abstract
The effect of patent ductus arteriosus (PDA) treatment with cyclooxygenase (COX) inhibitors (indomethacin [INDO] and ibuprofen [IBU]) on regional oxygenation requires further clarification. The authors hypothesized that both INDO and IBU reduce regional tissue oxygenation in preterm neonates with PDA but that the risk is not uniform for different tissues and other factors may contribute. Regional cerebral (rSO(2-C)), renal (rSO(2-R)), and mesenteric (rSO(2-M)) tissue oxygenation measured by near-infrared spectroscopy and peripheral arterial oxygen saturation measured by pulse oximetry were recorded simultaneously before, during, and after treatment with the first dose of INDO or IBU in very preterm-born infants with PDA. Tissue-specific fractional oxygen extraction (FOE) was calculated using the rSO(2-C), rSO(2-R), rSO(2-M), and corresponding SpO(2) measurements. The findings showed a significant reduction in rSO(2-C), rSO(2-R), and rSO(2-M) and an increase in regional FOE after treatment with COX inhibitors in approximately one third of the 38 enrolled infants, which were associated with increased baseline regional tissue oxygen saturation (p < 0.01). However, the infants with posttreatment reduction of tissue oxygenation had significantly lower baseline rSO(2-C) (66.7 ± 8.1 vs 69.7 ± 8.1 %), rSO(2-R) (55.2 ± 10.8 vs 62.7 ± 11.8 %) and especially rSO(2-M) (37.8 ± 11.4 vs 46.7 ± 16.0 %) than the neonates with unchanged or increased tissue oxygenation. The two groups did not differ in terms of the risk for posttreatment reduction in regional tissue oxygenation with respect to either INDO or IBU treatment and their respective blood levels. Treatment of PDA with either INDO or IBU is associated with a 30-40 % risk for a reduction in regional tissue oxygenation, which is more pronounced in mesenteric tissue than in cerebral or renal tissue. Despite the inconsistency, reduction of regional tissue oxygenation in preterm infants with PDA is more likely associated with the administration of INDO than with the administration of IBU.

Abstract
When medical management is warranted for closure of a persistent patent ductus arteriosus (PDA) in premature infants, treatment with a cyclooxygenase (COX) inhibitor is indicated. Indomethacin, available since 1976, has been the conventional pharmacologic treatment for PDA, but its use is associated with vasoconstrictive effects that impair renal, mesenteric and cerebral blood flow. Intravenous (IV) ibuprofen lysine, approved in the United States in 2006, has less severe vasoconstrictive effects on these vital organs than IV indomethacin. Clinical trials have shown both of these COX inhibitors to be equally effective in closing the PDA in approximately 70%-80% of treated infants, with less vasoconstrictive and adverse renal effects occurring with IV ibuprofen lysine.1,2 Several clinical considerations are important in the process of medical decision-making when faced with the need for PDA treatment with one of these pharmacologic agents in the premature infant. This paper focuses on these clinical considerations, including cerebral, renal and mesenteric blood flow, renal function, pulmonary effects, protein-binding capacity as it relates to hyperbilirubinemia, and platelet aggregation. No differences in chronic lung disease, pulmonary hypertension, hyperbilirubinemia and coagulopathy were observed in clinical trials when comparing these 2 COX inhibitors; however, significant differences have been observed in arterial blood flow to the cerebral, renal and mesenteric organs, suggesting that IV ibuprofen lysine may be the more favorable agent.

Abstract
Infestation with Entamoeba histolytica is especially common in areas with low socioeconomic status. Extra intestinal invasive involvement is more frequent in young children with significant mortality. This disease is rarely reported in the newborns. This 19-day-old newborn who was infected with orally given surgar solution is presented. He was successfully treated with omidazole.

Abstract
This study examined the response of the patent ductus arteriosus (PDA) to intravenous Indomethacin using serial two dimensional and Doppler echocardiography and documented the complications associated with therapy. Thirty-six preterm neonates who were oxygen and ventilator dependent were studied when they were aged 3-7 days. The PDA initially closed in 22 (61%) and constricted in seven (19%) of the infants. It was non-responsive in five (14%) and the treatment was stopped because of complications in two (6%). Only three (43%) of seven neonates given a second course had PDA closure. In the 25 instances where there was PDA closure following Indomethacin, re-opening was documented echocardiographically on three (12%) occasions. Overall, Indomethacin therapy was successful in 29 (81%) neonates, PDA ligation was required in four (11%) and three died from unrelated causes. Three (8%) neonates developed major complications: multiple gastric perforations in the first, focal ileal perforation in the second, and necrotizing enterocolitis in the third. Treatment failure, PDA ligation and major complications occurred exclusively in neonates less than 28 weeks gestation. In view of the relatively low efficacy and high major complication rate in these extremely preterm infants, a randomized clinical trial needs to be conducted using two dimensional and Doppler echocardiography to allow accurate assessment of the PDA response to intravenous Indomethacin.

Abstract
Entamoeba histolytica, the premier intestinal protozoan, has traversed time in its relentless quest for survival in its dichotomous role of parasite and pathogen. Enigmatic in its transition from human intestinal commensal to invader of human tissue, diverse in its pathogenicity for the human host, and intricate in its bacterial interrelationship in the bowel, E. histolytica has become the focal point of intensive investigation in its basic biology underscoring human pathogenicity. This review will focus on facets of cell biology, pathophysiology, clinical, therapeutic, and epidemiologic, correlates, along with diagnostic modalities and future research trends.

Abstract
Follow-up evaluation was performed on two groups of children, all premature infants who had undergone surgical ligation of a patent ductus arteriosus in the first days of life (Group I, 12 months postligation; Group II, 4 years postligation). Overall, two of 11 patients had significant functional scoliosis associated with weakness of shoulder girdle musculature and three additional patients had functional weakness on the affected side but with normal vertebral alignment. Patients post-patent ductus ligation should be observed for this long-term complication.

Abstract
One hundred sixteen infants who underwent on-unit ligation of patent ductus arteriosus (PDA) were examined for developmental sequelae. Mean gestational age of the study group was 29.1 weeks; mean birth weight, 1,232 gm; and mean duration of follow-up, 20.7 months (chronological age). Seven infants died of severe bronchopulmonary dysplasia (4) and severe central nervous system dysfunction (3) before they were 3 years old. Sixty-five percent of the remaining infants exhibited normal motor and mental development, although 58% showed some degree of postnatal growth retardation. There was no evidence of left arm dysfunction caused by the thoracic incision; 3 infants had minor problems with nonabsorbed sutures at 3 to 6 months of age. No infant demonstrated recurrence of ductal patency. Mild sensorineural handicaps not expected to be of long-term importance were noted in 20 infants. Eighteen other infants (15.5%) were classified as having moderate to severe impairments, which may have substantial impact on development and ability to function. Surgical ligation of PDA in premature infants has been shown to be safe and effective in the short run. Long-term follow-up suggests that infants who undergo PDA ligation do not appear to be at increased risk for sensorineural handicaps.

Abstract
The maturation of the lung is one of the greatest challenges the premature infant must face after birth. Premature infants have been observed to have a higher prevalence of patency of the ductus arterious, presenting the physician with a dilemma and a challenge. This article discusses the clinical and pathophysiologic manifestations and the management of patent ductus arteriosus in the premature infant.

Abstract
Reported are 1-year follow-up results of a randomized clinical trial comparing three strategies of managing clinically significant patent ductus arteriosus at the time of diagnosis in premature infants: (1) immediate administration of a three-dose course of intravenously administered indomethacin in addition to usual medical therapy (fluid restriction and use of diuretics or digitalis or both), with surgery as a backup measure, (2) usual medical therapy alone initially, with indomethacin as the first and surgery as the final backup measure, and (3) usual medical therapy alone initially, with surgery alone as backup. Of primary concern were the relative merits of these three managements strategies in the terms of the long-term occurrence of a wide range of health problems. Although at the time of neonatal hospitalization there was a significant excess of bleeding episodes in infants receiving indomethacin as part of initial treatment, and a significantly higher rate of retrolental fibroplasia in the those given usual medical therapy with surgery as backup, there were no statistically significant differences at 1 year of age related to these intermediate outcomes. In other regards, too, the treatment strategies appeared interchangeable in terms of the 1-year outcome.
