Since its initial discovery almost a century ago, vitamin K has been labeled as both lifesaving and malignancy causing. This has led to debate of not only its use in general but also regarding its appropriate dose and route. In this article, we review through a historical lens the past 90 years of newborn vitamin K from its discovery through to its modern use of preventing vitamin K deficiency bleeding (VKDB). Although researchers in surveillance studies have shown considerable reductions in VKDB following intramuscular vitamin K prophylaxis, ongoing barriers to the universal uptake of vitamin K prophylaxis remain. Reviewing the history of newborn vitamin K provides an opportunity for a greater understanding of the current barriers to uptake that we face. Although at times difficult, improving this understanding may allow us to address contentious issues related to parental and health professional beliefs and values as well as improve overall communication. The ultimate goal is to improve and maintain the uptake of vitamin K to prevent VKDB in newborns.
Purpose: Use of umbilical catheters is standard practice in neonatal intensive care units due to ease of insertion and provision of longer-term vascular access. Complications of umbilical venous catheters, including extravasation of total parenteral nutrition (TPN) fluid, are rare but when they occur have high mortality and morbidity. Umbilical venous catheters tend to migrate over time, and their position may change, so a high index of suspicion should be maintained. Our aim was to describe a case with extravasation of parenteral nutrition fluid and review the medical literature. Patients and Methods: Case report. Results: The infant was born at 28 weeks' gestation (1510 g). On day 6 he presented with nonspecific abdominal distension, hypotension, respiratory deterioration, metabolic acidosis and was critically ill. Radiological and ultrasound findings were consistent with TPN ascites due to a malpositioned umbilical venous catheter. Bedside paracentesis without laparotomy was carried out. Despite a stormy course, the infant recovered and the liver injury with conjugated hyperbilirubinemia improved over a period of several months. Conclusion: Emergency bedside ultrasound and paracentesis with catheter removal may be lifesaving and avoid laparotomy in an already critically unwell preterm infant.
Background and aims Complete atrioventricular block (CAVB) is associated with poor clinical outcomes in ST-elevation myocardial infarction (STEMI). This study determined the frequency and outcomes of primary percutaneous coronary intervention (PPCI) in patients with CAVB with acute inferior STEMI. Methods We conducted an observational, prospective study and enrolled 151 patients who were diagnosed with inferior STEMI. All patients received PPCI. The clinical outcomes were compared in patients with and without CAVB. The data was recorded on a collection form and analyzed on Statistical Package for Social Sciences (SPSS) software. Descriptive statistics were applied. For quantitative variables, standard deviation and mean were obtained, and statistical tests were also applied. Results Baseline characteristics were homogeneous in all patients. Half of the study population was either diabetic or hypertensive. Out of 151 participants, 21 (13.9%) developed CAVB. Two-thirds of the patients, who had developed heart block, reverted after PPCI. After a follow-up of two weeks, in-hospital mortality did not differ between the groups. Conclusion We conclude that PPCI can improve outcomes of CAVB-complicated acute inferior STEMI and suggest that primary PCI should be the preferred reperfusion therapy in patients with CAVB with STEMI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
