INTRODUCTION: Paragangliomas are neuroendocrine tumors arising from chromaffin cells located in sympathetic paraganglia. Mediastinal paragangliomas are extremely rare and can be classified as functional or non-functional according to their ability for secreting catecholamines. Patients can be asymptomatic and the diagnosis is usually incidental. Complete surgical resection remains the standard of care for paragangliomas. PRESENTATION OF CASE: We present a 44-year-old woman with a functional mediastinal paraganglioma incidentally found during the perioperative imaging workup for a diagnosed breast carcinoma...

Cesar Monzo, Philip A Stansly
The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is the key pest of citrus wherever it occurs due to its role as vector of huanglongbing (HLB) also known as citrus greening disease. Insecticidal vector control is considered to be the primary strategy for HLB management and is typically intense owing to the severity of this disease. While this approach slows spread and also decreases severity of HLB once the disease is established, economic viability of increasingly frequent sprays is uncertain. Lacking until now were studies evaluating the optimum frequency of insecticide applications to mature trees during the growing season under conditions of high HLB incidence...

This research proposes the various versions of modified cuckoo search (MCS) metaheuristic algorithm deploying the strength Pareto evolutionary algorithm (SPEA) multiobjective (MO) optimization technique in rectangular array geometry synthesis. Precisely, the MCS algorithm is proposed by incorporating the Roulette wheel selection operator to choose the initial host nests (individuals) that give better results, adaptive inertia weight to control the positions exploration of the potential best host nests (solutions), and dynamic discovery rate to manage the fraction probability of finding the best host nests in 3-dimensional search space...

INTRODUCTION: Little data exists regarding optimal therapeutic strategies post-operatively after lung transplant (LTx). Current practice patterns rely on expert opinion and institutional experience resulting in non-uniform post-operative care. To better define current practice patterns, an international survey of LTx clinicians was conducted. METHODS: A 30-question survey was sent to transplant clinicians via email to the ISHLT open forum mailing list and directly to the chief transplant surgeon and pulmonologist of all LTx centers in the United States...

F A Chaudhry
Achilles tendinopathy is a common overuse condition affecting the adult population. The incidence is on the rise because of greater participation of people in recreational or competitive sporting activities. There are several treatment options available both non-operative and operative. Ultrasound-guided dry needling and high-volume image-guided injection is relatively a new procedure. The aim of this study was to find out the effectiveness of dry needling and HVIGI in the management of mid-portion chronic Achilles tendinopathy by performing a literature review...

BACKGROUND: There is no consensus on reporting non-mortality trauma complications in a graded manner. The Clavien-Dindo scale of complications was originally for elective surgery, and requires adaptation to provide meaningful data for trauma patients. In particular the original score does not account for those treated without surgery. We report an adapted Clavien-Dindo in trauma (ACDiT) scale and apply it to patients managed operatively and non-operatively. METHODS: A combined prospective and retrospective international multi-center observational study was undertaken to apply the ACDiT scale to 484 trauma patients at 3 university teaching hospitals (Birmingham, England (n=303); Houston, Texas (n=113); and Glasgow, Scotland (n=68))...

INTRODUCTION: Existing trials studying the use of Gastrografin for management of adhesive small bowel obstruction (SBO) are limited by methodological flaws and small sample sizes. We compared institutional protocols with and without Gastrografin (GG), hypothesizing that a SBO management protocol utilizing GG is associated with lesser rates of exploration, shorter length of stay, and fewer complications. METHODS: A multi-institutional, prospective, observational study was performed on patients appropriate for GG with adhesive SBO...

Management and prognosis of diseases requires the measurement in non- or minimally invasively collected samples of specific circulating biomarkers, consisting of any measurable or observable factors in patients that indicate normal or disease-related biological processes or responses to therapy. Therefore, on-site, fast and accurate determination of these low abundance circulating biomarkers in scarcely treated body fluids is of great interest for health monitoring and biological applications. In this field, electrochemical DNA sensors (or genosensors) have demonstrated to be interesting alternatives to more complex conventional strategies...

OBJECTIVE/BACKGROUND: Biomarker(s) for prediction of the future progression rate of abdominal aortic aneurysms (AAA) may be useful to stratify the management of individual patients. AAAs are associated with features of systemic inflammation and endothelial dysfunction. Flow mediated dilatation (FMD) of the brachial artery is a recognised non-invasive measurement for endothelial function. We hypothesised that FMD is a potential biomarker of AAA progression and reflects the temporal changes of endothelial function during AAA progression...

In this work we have developed a novel, robust practical control structure to regulate an industrial methanol distillation column. This proposed control scheme is based on a override control framework and can manage a non-key trace ethanol product impurity specification while maintaining high product recovery. For comparison purposes, a MPC with a discrete process model (based on step tests) was also developed and tested. The results from process disturbance testing shows that, both the MPC and the proposed controller were capable of maintaining both the trace level ethanol specification in the distillate (XD) and high product recovery (β)...

Phallic reconstruction is an important part of management for congenital aphallia. Scrotal flap phalloplasty has been described in pediatric patients to create the appearance of a non-functioning phallus. We describe a modified scrotal flap technique with the addition of an acellular dermal matrix patch (AlloDerm®) to provide additional girth and support to the phallus. The post-operative cosmetic outcome has been satisfactory and there is no documented complication over a 12 month follow-up. Alloderm® dermal matrix can be a safe addition to phallic reconstruction and its overall application needs to be further studied...

BACKGROUND: The operation of choice for patients with chronic ulcerative colitis (CUC) is restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Pouchitis is the most common complication after IPAA. The incidence of Clostridium difficile infection (CDI) is higher in CUC patients than the general population and can lead to significant disease flares and higher rates of colectomy. We sought to determine the risk of pouchitis in patients with precolectomy CDI and 90-day postoperative IPAA complications...

BACKGROUND & AIMS: Despite evidence that most non-malignant colorectal polyps can be managed endoscopically, a substantial proportion of patients with a non-malignant colorectal polyp are still sent to surgery. Risks associated with this surgery are not well characterized. We aimed to describe 30-day post-operative morbidity and mortality and to explore risk factors for adverse events in patients undergoing surgical resection for non-malignant colorectal polyps. METHODS: We analyzed data collected prospectively as part of the National Surgical Quality Improvement Program...
