BACKGROUND: Uncomplicated appendicitis may resolve spontaneously or require treatment with antibiotics or appendicectomy. The aim of this randomized trial was to compare the outcome of a non-antibiotic management strategy with that of antibiotic therapy in uncomplicated appendicitis. METHODS: Patients presenting to a university teaching hospital with CT-verified uncomplicated simple appendicitis (appendiceal diameter no larger than 11 mm and without any signs of perforation) were randomized to management with a no-antibiotic regimen with supportive care (intravenous fluids, analgesia and antipyretics as necessary) or a 4-day course of antibiotics with supportive care...

Neonatal appendicitis is a rare clinical entity associated with remarkable morbidity and mortality. Appendicular perforation is common and the diagnosis is usually made intra-operatively. The causative etiology of neonatal perforated appendicitis (NPA) is a subject of debate and has not been elucidated. Although many etiologic theories exist, increasing evidence suggests a subset of NPA cases may represent a form of necrotizing enterocolitis (NEC) localized to the appendix. We herein present a review of the current literature to include cases of NPA attributed to localized NEC...

BACKGROUND: CT radiation is arguably carcinogenic. Results from single-centre studies, mostly retrospective, have advocated lowering the CT radiation dose for the diagnosis of appendicitis. However, adoption of low-dose CT has been slow. We aimed to assess the effectiveness of low-dose CT compared with standard-dose CT in the diagnosis of appendicitis in adolescents and young adults. METHODS: We did this pragmatic, multicentre, randomised controlled non-inferiority trial at 20 South Korean teaching hospitals with little experience with low-dose CT...

BACKGROUND: The acute care surgery (ACS) model was developed to acknowledge the complexity of a traditionally fractured emergency general surgery patient population; however there are variations in the design of ACS service models. This meta-analysis analyzes the impact of implementation of different ACS models on the outcomes for appendicitis and biliary disease. STUDY DESIGN: A systematic, English-language search of major databases was conducted. From 1,827 papers, 2 independent reviewers identified 25 studies that reported on outcomes for patients with appendicitis (13) biliary disease (7) or both (5) before and after implementation of an ACS service...

Enrichment of uranyl from seawater is crucial for the sustainable development of nuclear energy but current uranium extraction technology suffers from multiple drawbacks of low sorption efficiency, slow uptake kinetics, or poor extraction selectivity. Herein, we prepared the first example of amidoxime appended metal-organic framework UiO-66-AO by post-synthetic modification method for rapid and efficient extraction of uranium from seawater. UiO-66-AO can remove 94.8% of uranyl ion from Bohai seawater within 120 min and 99% of uranyl ion from Bohai seawater containing extra 500 ppb uranium within 10 min...

A new diamine-functionalized metal-organic framework comprised of 2,2-dimethyl-1,3-diaminopropane (dmpn) appended to the Mg(2+) sites lining the channels of Mg2(dobpdc) (dobpdc(4-) = 4,4'-dioxidobiphenyl-3,3'-dicarboxylate) is characterized for the removal of CO2 from the flue gas emissions of coal-fired power plants. Unique to members of this promising class of adsorbents, dmpn-Mg2(dobpdc) displays facile step-shaped adsorption of CO2 from coal flue gas at 40 °C and near complete CO2 desorption upon heating to 100 °C, enabling a high CO2 working capacity (2...

Trimodal simultaneous acquisition of positron emission tomography (PET), magnetic resonance imaging (MRI), and electroencephalography (EEG) has become feasible due to the development of hybrid PET-MR scanners. To capture the temporal dynamics of neuronal activation on a millisecond-by-millisecond basis, an EEG system is appended to the quantitative high resolution PET-MR imaging modality already established in our institute. One of the major difficulties associated with the development of simultaneous trimodal acquisition is that the components traditionally used in each modality can cause interferences in its counterpart...

One of the most commonly injured structures of the thumb metacarpophalangeal (MCP) joint is the ulnar collateral ligament (UCL). An acute injury of this ligament is often amenable to primary repair. Despite the favorable outcomes of primary repair, the thumb is often restricted during initial healing of the ligament with immobilization and delayed rehabilitation. We present a novel technique to augment the repair of the UCL with suture tape to provide immediate biomechanical support and strength during the critical time of ligament healing...

Recent developments in paediatric gastrointestinal surgery have focused on minimally invasive surgery, the accumulation of high-quality clinical evidence, and scientific research. The benefits of minimally invasive surgery for common disorders like appendicitis and hypertrophic pyloric stenosis are all supported by good clinical evidence. Although minimally invasive surgery has been extended to neonatal surgery, it is difficult to establish its role for neonatal disorders such as oesophageal atresia and biliary atresia through clinical trials because of the rarity of these disorders...

INTRODUCTION: Chickenpox is caused by varicella zoster virus (VZV). Although predominantly a mild disease, it can cause considerable morbidity and in rare occasions even mortality in healthy children as well as increased morbidity and mortality in immunocompromised patients. The aetiology of appendicitis is largely unknown but is thought to be multifactorial. Appendicitis is a suspected, but not well documented, complication from varicella zoster virus infection. CASE PRESENTATION: A five-year-old girl diagnosed with DiGeorge syndrome and a prolonged primary VZV infection was admitted due to abdominal pain, increasing diarrhoea, vomiting, and poor general condition...

INTRODUCTION: There is a significant burden on public health systems from emergency surgical and trauma (ESAT) patients. In Western countries, the response has been to separate acute and elective surgery with the creation of a new sub-specialty: acute care surgery. Dedicated acute units have shown improvements in efficiency and clinical outcomes for patients. The aim of this study was to assess the results of the first such unit in Singapore. MATERIALS AND METHODS: A retrospective analysis was performed of a 12-month period of acute admissions between May 2014 and April 2015, with comparison of 6-months before and after the creation of the ESAT service...

Diabetic retinopathy (DR) is a consequence of diabetes and is the leading cause of blindness among 18- to 65-year-old adults. Regular screening is critical to early detection and treatment of DR. Computer-aided diagnosis has the potential of improving the practice in DR screening or diagnosis. An automated and unsupervised approach for retrieving clinically relevant images from a set of previously diagnosed fundus camera images for improving the efficiency of screening and diagnosis of DR is presented. Considering that DR lesions are often localized, we propose a multiclass multiple-instance framework for the retrieval task...

A young man was admitted due to gastrointestinal obstruction and was diagnosed as having cocoon peritonitis secondary to perforated appendicitis. He suffered from small intestine partial obstruction because of multiple adhesion bands whose obstructive symptoms completely resolved after single balloon enteroscopy. So balloon enteroscopy could be offered as a therapeutic option for partial small intestine obstruction.
