The acid-base and copper(ii) coordination properties of three previously described cyclam derivatives are reported. Potentiometry, mass spectrometry, UV-vis absorption spectroscopy, electrochemistry and theoretical calculations were combined to investigate the protonation and binding properties of Bn-cyclam-EtOH (L1), oxo-cyclam-EtOH (L2) and oxo-Bn-cyclam-EtOH (L3). These three cyclams are C-functionalized by a hydroxyethyl pendant arm and display either one N-benzyl group and/or an amide replacing one macrocyclic secondary amine...

In order to improve the resolving power (RP) and signal-to-noise ratio (SNR) of ion mobility spectrometry (IMS) simultaneously, a modified Hadamard transform-inverse ion mobility spectrometry (MHT-IIMS) technique was developed. In this novel technique, a series of isolating codes were appended to each element of the pseudo random binary sequence (PRBS), and then the modified modulation sequence was formed and used to control the ion gate of the inverse IMS (IIMS). Experimental results demonstrate that the MHT-IIMS technique can significantly enhance the resolving power and SNR simultaneously by measuring the spectra of reaction ions...

OBJECTIVES: To compare conservative treatment with index admission appendicectomy in children with acute uncomplicated appendicitis. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, Embase and the Cochrane Library (CENTRAL) from 1950 to 18 February 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies that assessed both appendicectomy and non-operative management of acute uncomplicated appendicitis in children of less than 18 years of age...

OBJECTIVES: Abdominal pain is a common pediatric complaint to emergency departments (EDs), and clinicians often rely on imaging for diagnosis. Studies have demonstrated an increase in computed tomography (CT) in this population. Following emphasis on radiation reduction by researchers and organizations, this study evaluates recent national trends in CT use among pediatric patients presenting to EDs with abdominal pain. METHODS: This is a cross-sectional analysis of ED patients 18 years or younger with chief complaint of abdominal pain in the National Hospital Ambulatory Medical Care Survey from 2008 to 2011...

Primary omental torsion is a rare cause of acute abdominal pain with a clinical presentation resembling acute appendicitis. Here, we report the case of a 7-year-old child presenting with right lower quadrant pain. Primary omental torsion was discovered upon laparoscopy, and the torsed omentum was excised without postoperative complications. Potential causes, contributing factors, diagnosis, and treatment are discussed.

PURPOSE: To evaluate in pediatric patients the diagnostic performance of magnetic resonance imaging (MRI) for suspected appendicitis and its negative appendectomy rate. MATERIALS AND METHODS: The study involved diagnostic accuracy studies that used MRI for pediatric patients with suspected appendicitis. Various field strengths and sequences were used in each included study. The diagnostic accuracy of MRI in pediatric patients with suspected appendicitis and negative appendectomy rate were assessed...

BACKGROUND AND OBJECTIVES: Nonoperative management (NOM) of uncomplicated pediatric appendicitis has promise but remains poorly studied. NOM may lead to an increase in resource utilization. Our objective was to investigate the trends in NOM for uncomplicated appendicitis and study the relevant clinical outcomes including subsequent appendectomy, complications, and resource utilization. METHODS: Retrospective analysis of administrative data from 45 US pediatric hospitals...

PURPOSE: Acute appendicitis (AA) is among the most common causes of lower abdominal pain and admissions to the emergency department. Over the past 20 years, there has been a renewed interest in the conservative management of uncomplicated AA, and several studies demonstrated that an antibiotic-first strategy is a viable treatment option for uncomplicated AA. The aim of this prospective non-randomized controlled, multicenter trial is to compare antibiotic therapy and emergency appendectomy as treatment for patients with uncomplicated AA confirmed by US and/or CT or MRI scan...

BACKGROUND: Acute appendicitis is the commonest nonobstetric surgical emergency during pregnancy. The aim of the study was to compare perioperative outcomes of acute appendicitis in pregnant and nonpregnant patients. METHODS: A retrospective review of medical records of 56 pregnant patients between 2011 and 2016 who were compared with 164 nonpregnant women of reproductive age who underwent open appendectomy between 2014 and 2016 for acute appendicitis. The patient's demographics and perioperative data were analyzed...

Neuroendocrine neoplasms are the most common epithelial tumors among appendix tumors. Appendix tumors that are completely or partially composed of neuroendocrine cells are divided into two categories: Classic carcinoid tumors and goblet cell carcinoid tumors (GCCT). They are known to progress more aggressively than classic (neuro) endocrine tumors. In this study, three cases with acute appendicitis symptoms are presented, including their clinical and histopathological findings. Microscopic examination detected GCCT in two cases and mixed adenoneuroendocrine carcinoma in one case, in addition to acute appendicitis...

BACKGROUND: Radiation exposure is the reason for the decreased utilization of computed tomography (CT) in pediatric centers (PCs). We sought to compare the radiation dose exposure of CT imaging performed at outside hospitals (OH) versus PC in pediatric patients with acute appendicitis (AA). MATERIAL AND METHODS: A retrospective review of all patients managed at our PC for AA from January 2011 to March 2016 was performed. Patients who had CT imaging for AA at OH were compared to those who underwent CT for appendicitis at our PC...

BACKGROUND: Institutional protocols for preincisional antibiotic prophylaxis can standardize care and improve outcomes. However, challenges remain in compliance with such protocols for urgent or emergent operations. We hypothesized that compliance with an institutional protocol for antibiotic prophylaxis for appendectomy for appendicitis in pediatric patients results in reduced surgical site infections (SSIs) after simple appendectomy. METHODS: This retrospective study assessed all pediatric patients (≤18 y) who underwent appendectomy for confirmed simple appendicitis at a tertiary children's hospital between 2012 and 2015...

BACKGROUND: Patients managed non-operatively have been excluded from risk-adjusted benchmarking programs, including the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP). Consequently, optimal performance evaluation is not possible for specialties like emergency general surgery (EGS) where non-operative management is common. We developed a multi-institutional EGS clinical data registry within ACS NSQIP that includes patients managed non-operatively to evaluate variability in non-operative care across hospitals and identify gaps in performance assessment that occur when only operative cases are considered...

Most of graph construction techniques assume a transductive setting in which the whole data collection is available at construction time. Addressing graph construction for inductive setting, in which data are coming sequentially, has received much less attention. For inductive settings, constructing the graph from scratch can be very time consuming. This paper introduces a generic framework that is able to make any graph construction method incremental. This framework yields an efficient and dynamic graph construction method that adds new samples (labeled or unlabeled) to a previously constructed graph...

BACKGROUND: Duplex appendix is very rare (incidence 0.004%) but has clinical relevance given the frequency of appendicectomies performed. Failure to recognise duplication can result in failure of treatment and medico-legal consequences. A review of published cases was undertaken to identify factors that may help in managing this rare condition. METHODS: All English and non-English publications were identified in PubMed, Embase and Cochrane databases. Patient demographics, intraoperative findings, anatomical details and histopathology were analysed...

A 17-year-old boy with no medical comorbidities, but a significant family history of malignancy, presented to Accident and Emergency following 3 days of increasing rectal pain, symptoms of bladder outflow obstruction (poor flow, intermittent stream and hesitancy) and dysuria. Notably he had no abdominal pain. Digital rectal examination revealed a tender, enlarged prostate. Inflammatory markers were significantly raised (white cell count 17.7, C reactive protein 191). He was diagnosed clinically as prostatitis and commenced on intravenous antibiotics...
