Association of hemochromatosis with infectious diseases: expanding spectrum

SummaryWithholding iron from potential pathogens is a host defense strategy. There is evidence that iron overload per se compromises the ability of phagocytes to kill microorganisms. Several hypotheses exist to explain the association of hemochromatosis with infection. A combination of mechanisms likely contributes to the increase in susceptibility to infection in these patients. A review of the current literature delineating various pathogens to which patients with hemochromatosis are potentially susceptible, and recent advances in the understanding of the association of hemochromatosis with infection, are discussed

An Action Plan for Adaptation in Bangladesh Agriculture under Climate Change

This report is the outcome of a study titled 'An Action Plan for Adaptation in Bangladesh Agriculture under Climate Change', carried out with support from the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). This report prepared by the Center for Environmental and Geographic Information Services (CEGIS) delineates an action plan to prioritize adaptation options after considering the inputs by experts and scrutiny by stakeholders. It aims to promote precision agriculture and commercialization of crop agriculture with strong institutional and financial footing to tackle climate change

The need for national medical licensing examination in Saudi Arabia

<p>Abstract</p> <p>Background</p> <p>Medical education in Saudi Arabia is facing multiple challenges, including the rapid increase in the number of medical schools over a short period of time, the influx of foreign medical graduates to work in Saudi Arabia, the award of scholarships to hundreds of students to study medicine in various countries, and the absence of published national guidelines for minimal acceptable competencies of a medical graduate.</p> <p>Discussion</p> <p>We are arguing for the need for a Saudi national medical licensing examination that consists of two parts: Part I (Written) which tests the basic science and clinical knowledge and Part II (Objective Structured Clinical Examination) which tests the clinical skills and attitudes. We propose this examination to be mandated as a licensure requirement for practicing medicine in Saudi Arabia.</p> <p>Conclusion</p> <p>The driving and hindering forces as well as the strengths and weaknesses of implementing the licensing examination are discussed in details in this debate.</p

Meningitis due to Enterobacter aerogenes subsequent to resection of an acoustic neuroma and abdominal fat graft to the mastoid

Meningitis is an uncommon complication of neurosurgical procedures, with an incidence of 1.1% to 2.5%. Although unusual, the frequency of nosocomial Gram-negative meningitis appears to be increasing. Gram-negative meningitis has been documented following disruption of the dura-arachnoid barrier secondary to trauma or surgery. The association of Gram-negative bacillary meningitis with neurosurgical procedures was first reported in the 1940's. Wolff et al. described the association between Enterobacter species and post-neurosurgical infection. More recently, risk factors for nosocomial Enterobacter meningitis have been characterized by Parodi et al. Adipose graft, as an independent risk factor has not yet been reported. A patient with acoustic neuroma resection, who developed bacterial meningitis from an abdominal fat pad graft to a mastoidectomy bed is described. A brief overview was made of post-neurosurgical Gram-negative meningitis

Multiple Subcutaneous Mycetomas caused by Pseudallescheria boydii: Response to therapy with oral potassium iodide solution

We describe the case of a sixteen-year-old male who presented with multiple subcutaneous mycetomas proven on culture to be secondary to Pseudallescheria boydi., The lesions responded completely to oral potassium iodide solution. To our knowledge this has never been reported in humans

Comparing Techniques for Removal of Separated Endodontic Instruments: Systematic Review and Meta-analysis

Purpose: The goal of this study is to look into several approaches to approaching damaged instruments in the root canal, as well as to show possible outcomes in terms of dentin thickness, fracture resistance, technique success, and clinical time. Methodology: PubMed, Cochrane, Lilacs, Web of Science, Scopus, grey literature, and manual searches were used to conduct the bibliographic research. The titles and abstracts of 506 papers were examined using the inclusion and exclusion criteria. Sixty items were chosen and read in their entirety. This systematic review includes fourteen papers. Results: The ultrasonic approach was the most extensively researched and yielded positive results in general. The more apically positioned the tool is, the more difficult it is to remove it, the more dentin is removed, and the poorer the tooth's fracture resistance. When removal is not possible, the bypass technique (bypassing) can be employed, and the GentleWave System approach can be used on weakened teeth or with little dental fragments. Conclusion: The data from laboratory investigations showing the curvature and root third in which instrument fractures originate is related to fracture resistance and success is presented in this comprehensive review

DENSITY AND PLANTING DATE INFLUENCE PHENOLOGICAL DEVELOPMENT ASSIMILATE PARTITIONING AND DRY MATTER PRODUCTION OF FABA BEAN

Abstract Phenological development determines the period of vegetative and reproductive growth, assimilate partitioning and dry matter production. Planting time and density are the major factors affecting phenological development, assimilate partitioning and yield of faba bean. The aim of this study was to evaluate the effect of planting date and plant density on phenological development, assimilate partitioning and yield of faba bean. Faba bean was planted on eight dates from Septembe
