Ionic Rare Earths Ltd has reported a potential 30-50% reduction in the carbon footprint of its rare earth oxide (REO) production compared to conventional producers. A preliminary Life Cycle Assessment (LCA) conducted by Minviro on the magnet recycling process of subsidiary Ionic Technologies has highlighted significant environmental benefits. The results are undergoing peer review, with final findings expected in March 2025. Ionic Technologies' Belfast commercial recycling plant will focus on Didymium oxide ((NdPr)₂O₃) and Dysprosium oxide (Dy₂O₃), with additional analysis on Neodymium oxide (Nd₂O₃). The study also assessed the environmental impact of applying IXR's magnet REO products in direct drive wind turbine generators using Rare Earth Permanent Magnet (REPM) technology. The company aims to support a more sustainable rare earth supply chain, particularly in Europe, reducing dependence on Chinese markets. IXR is working with Less Common Metals and Ford Technologies to establish a UK-based recycled magnet supply chain, with Ford using these materials at its EV drive train facility in Halewood. Ionic Rare Earths expects the final study results to reinforce the advantages of its patented process and strengthen its position in decarbonising rare earth supply chains. #IonicRareEarths #RareEarths #MagnetRecycling #SustainableMining #ESG #CO2Reduction #Decarbonisation #ElectricVehicles #WindEnergy #GreenManufacturing #CircularEconomy #CriticalMinerals #NetZero #EnvironmentalImpact #CarbonFootprint #RenewableEnergy #SupplyChain #Recycling #AdvancedManufacturing #MiningInnovation

Have you noticed thermal expansion measurements on your clay or glaze recipes? If so you might be wondering what those measurements mean, and how you use them to predict glaze fit on a clay body. This week the gang discuss thermal expansion and why those numeric values aren't always so helpful. They also answer a listener question about glazes with rare earth elements. Do you have questions or need advice on glazes? Drop us a line at ForFluxSakePodcast@gmail.com and you could be featured on an upcoming show.   This week's episode features the following topics: Thermal expansion, glaze fit, clay body, rare earth elements, Praseodymium, Neodymium, Erbium Today's episode is brought to you by Cornell Studio Supply and the Rosenfield Collection of Ceramic Art.    

In this episode, we return to critical metals and how their fortunes are affected by the energy transition, technology and geopolitics. To tell that story we are focusing on three in particular: Neodymium, Gallium & Hafnium. Each has a key role in the modern world with demand set to grow but with challenges markets and policy makers are grappling with. Our guest is Ellie Saklatvala, Head of Non-Ferrous Pricing at Argus Media, the leading independent pricing agency.

This is: on neodymium magnets, published by bhauth on January 31, 2024 on LessWrong. Neodymium magnets are the main type used in modern motors. Why are they good? Are there any good alternatives? review of ferromagnetism Magnetic fields contain energy. In an inductor, that energy comes from an increase in voltage when current is first applied. When a magnetic core is added to an inductor and a stronger field is produced from the same added energy, that extra energy has to come from somewhere. The energy that ferromagnetic cores add to magnetic fields comes from their crystal structure fitting together better in a magnetic field. This implies that ferromagnetic cores should spontaneously magnetize to some extent, and they actually do; it's just that the spontaneously generated magnetic fields are curled into microscopic 3d loops. The microscopic internal field strength is approximately the saturation field of a ferromagnetic material, which is often greater than the field generated by a Nd magnet. Applying an external magnetic field causes those microscopic magnetic loops to partly unroll. The actual field is generated by unpaired electrons of atoms; individual electrons are very magnetic. But ferromagnetism isn't a property of atoms, it's a property of crystals; without particular crystal structures that favor magnetic fields, those unpaired electron spins of iron atoms would just cancel out. For example, stainless steels contain a lot of iron, but most aren't ferromagnetic. Atoms of crystals fitting together better in a magnetic field implies that iron cores slightly change shape when a magnetic field is applied. This effect is responsible for the humming noise transformers make, and has been used for eg sonar. common misconceptions Fucking magnets, how do they work? And I don't wanna talk to a scientist.

But again, ferromagnetism is a property of crystal structures, not atoms or elements. A lot of people think the magnetism of neodymium magnets comes from the neodymium, but the actual magnetism comes from the iron in them. The title of the quoted song is "Miracles".

Aclara Resources CFO Francois Motte joined Steve Darling from Proactive to share exciting news regarding the company's resource expansion through a significant discovery of ionic clay in Brazil. This discovery has led to the Inferred Resource Estimate for the Carina Module, reported in accordance with NI 43-101 guidelines, which stands at an impressive 168 million tonnes with a total rare earth oxide content of 1,510 ppm. Of particular importance is the presence of substantial quantities of critical rare earth elements such as Dysprosium, Terbium, Neodymium, and Praseodymium within the Carina resource. These rare earth elements hold significant importance in the manufacturing of electric vehicles and wind turbines, making this discovery highly relevant to the clean energy sector. Motte highlighted that Aclara's rare earth recovery process aligns seamlessly with the company's patented and successfully demonstrated processing technology at a pilot scale. This technology is specifically designed to minimize both cost and environmental impact. Notably, the ionic clays rich in rare earths will be extracted from a shallow open pit using mechanical excavation. Importantly, this process does not generate tailings, eliminating the need for a tailings storage facility. Looking ahead, Aclara Resources has ambitious plans to further enhance the resource base. This includes adding resources at depth through a reverse circulation (RC) drilling program already in progress and scheduled for completion in Q2 2024. Additionally, the company aims to produce samples by piloting Carina's ionic clays at Aclara's pilot plant in Chile during December 2023 and January 2024. These steps will pave the way for the completion of an initial Preliminary Economic Assessment in January 2024. This remarkable discovery and resource expansion highlight Aclara Resources' commitment to supplying critical rare earth elements essential for the growth of clean energy technologies while embracing environmentally responsible mining practices. #proactiveinvestors #aclararesourcesinc #tsx #ara #mining #RareEarthsDiscovery, #BrazilIonicClay, #ResourceExploration, #EconomicImpact, #GlobalResources, #MiningInnovation, #CFOInterview, #KarinaMemorialProject, #TechnologicalAdvancements, #MiningTechnology, #SustainableResources, #EconomicGrowth, #InvestmentOpportunity, #MineralExploration, #GreenMining, #EnvironmentalImpact, #FutureOfMining, #IonicClayDeposits, #MineralResources, #SustainableDevelopment, #MineralEconomics, #ResourceIndustryNews, #MiningUpdate, #StrategicMinerals#invest #investing #investment #investor #stockmarket #stocks #stock #stockmarketnews

American Rare Earths CEO Donald Swartz joined Steve Darling from Proactive to share an update on the company's work on metallurgical testing at its flagship Halleck Creek project in Wyoming. The preliminary test results have been highly positive, indicating that the ore can be effectively processed using conventional technologies. This approach not only requires less initial capital expenditure but also offers lower ongoing operating costs. The metallurgical testing has demonstrated a 28.5% increase in the recovery of Neodymium and Praseodymium Oxide compared to prior designs. The mineralization in the deposit primarily consists of allanite, and testing has shown that rare earth elements can be efficiently leached from allanite using atmospheric acid tank leaching. Acid tank leaching is a well-established mineral processing technology with low technical risk. It can process high volumes of concentrate in low-cost leach trains at below-boiling point temperatures, which is more cost-effective compared to traditional acid-baking kilns. The company's current exploration program is nearing completion, and core material obtained from this program will be sent to labs for the next phase of detailed metallurgical testing. These positive results suggest that American Rare Earths is making significant progress in developing an efficient and cost-effective process for extracting rare earth elements from the Halleck Creek project, which could have a positive impact on the project's economics. #proactiveinvestors #americanrareearths #asx #arr #otcqb #arrnf #MetallurgicalBreakthrough #RareEarthMetals #MiningNews #ResourceIndustry #SustainableMining #Metallurgy #Neodymium #Praseodymium #MiningTechnology #Innovation #EconomicOutlook #ExplorationProgram #MineralResources #EcoFriendlyMining #GreenTechnology #CapitalEfficiency #CostEffectiveMining #MineralExtraction #MiningInvestment #IndustryUpdates #RareEarthMarket #EnvironmentalSustainability #TechnologyAdvancements #ResourceSector#invest #investing #investment #investor #stockmarket #stocks #stock #stockmarketnews

'Als we al onze auto's zouden vervangen door elektrische auto's, zou dat verschrikkelijk zijn.' Neodymium, praseodymium, dysprosium: weinig mensen kennen ze, maar zeldzame aardmetalen zijn onmisbaar voor onze toekomst. De hiermee geproduceerde magneten zijn niet alleen essentieel voor smartphones, maar ook voor windmolens en elektrische auto's. Anders gezegd: zonder deze stoffen geen groene transitie. En de markt? Die is vrijwel volledig in Chinese handen. Het opzetten van een lokale productieketen kost decennia en de productie van de magneten is een vervuilend proces.

Donald Sadoway is an emeritus professor of materials chemistry at MIT and the chief science advisor at Ambri Incorporated, a molten-metal battery company based in Cambridge, Massachusetts. In this episode, Sadoway explains why lithium-ion batteries are so dangerous, why we need to develop batteries with super-cheap ingredients, Ambri's decade-long road to commercialization, the origin of the neodymium-iron-boron magnet, coercivity, and why iridium is his favorite element.

Jack Lifton, editor-in-chief InvestorIntel.com, has been writing about rare earth elements, critical minerals, and the companies that produce them for more than two decades. In this episode, he talks about China's dominance of the rare earths market and why its dominance will continue, why projections about huge increases in electric vehicle production in the U.S. are “nonsense,” and why humans are “mineral parasites.”

Siliconpolitik: The Upcoming Quad Summit-Pranay KotasthaneNews reports suggest that the first in-person Quad summit is likely to be held in September. The last online summit-level meeting created three working groups on vaccines, critical & emerging technologies (C&ET), and climate change.Though there has been some action on vaccine delivery, there are virtually no updates about the outcomes of the other two working groups. At least on the C&ET front, it seems to me that a vast agenda has bogged down any meaningful collaboration. To this day, it seems that the four countries do not even agree on which technologies are critical and emerging, and which aren’t. The four states will be looking for ways to get out of this rut as they meet in September. Hence it is useful to recommend C&ET ‘actionables’ that can be announced as part of this summit.I have earlier written why a semiconductor partnership would be an ideal start for the Quad C&ET collaboration. In this edition, here are a few tangible action items to begin this partnership.One, announce a Quad Semiconductor Supply Chain Resilience Fund. Think of this as a multi-sovereign wealth fund but for semiconductor investments across the Quad countries. This fund could focus on two areas:create a roadmap for new manufacturing facilities across the Quad countries. One of the focus areas should be to secure supplies not just at the leading-edge nodes but also at key trailing-edge nodes, which will continue to remain workhorses for automotive, communications (5G), and AI.Sponsor new standard developments such as composite semiconductors and create one centre for excellence in each Quad country in an area of its immediate interest. For example, Australia could host the CoE for new materials in electronics, Japan could host the CoE for silicon manufacturing equipment, while the US and India could host CoEs on specific fabless design architectures.Two, and this one is an even more ambitious goal, facilitate strategic alliances between companies in the four quad states. A precedent to learn from is the US-Japan arrangement in the early 1990s by when memory manufacturing had moved out from the US to Japan for cost reasons. The US National Research Council came out with a report in 1992 studying the types of alliances between US and Japanese semiconductor companies and recommended specific actions to take in furthering each of these arrangements. For example, the table below captured the sixteen types of alliances used by US and Japanese semiconductor companies.Nearly thirty years later, this typology remains a useful guide for Quad collaboration on semiconductors. Each area needs government facilitation. For example, reducing export control requirements between quad countries can aid more licensing, cross-licensing, and technology exchange arrangements. Similarly, lowering investment screening mechanisms for quad countries can accelerate joint development and acquisition arrangements. In short, there is much that can be done on the Quad C&ET agenda through the siliconpolitik route. Mineralpolitik: The Global Hustle for REEs -Aditya PareekRare Earth Elements(REE) are critical to modern high-tech supply chains. China has captured much of the Rare Earths market over the past three decades. One reason for this has been its willingness to bear the steep ecological cost of extracting and processing REEs. In 2010, during a dispute between China and Japan, the world got its first memorable jolt of how China’s dominance of the sector can affect the supply of everything - from strategically important tech to consumer electronics. Ever since, the need for diversifying and building separate supply chains not reliant on China has been felt and the COVID-19 induced disruption has only exacerbated these impulses. However, according to recently published data, as quoted in SCMP and Reuters, China’s Rare Earths exports have proliferated by a significant margin (25.3% compared to the first half of 2020 and 16.5% compared to the first half of 2019). While the US and other Quad states may be planning to shift away from China, it will take years for this to become a reality.According to an opinion piece in the Diplomat, Myanmar, which saw a military coup earlier this year, and has again become a pariah state to the West, is the “third-largest source of mined Rare Earths”. Most of these mines from which Mayanmar’s REEs come are in the long-troubled Kachin state region. Dysprosium is an important REE component in Neodymium magnets which in turn are used to build everything from basic motors in consumer electronics and appliances like cars, washing machines to all conceivable complex military equipment such as drones, combat vehicle engines, submarine electric propulsion systems etc.“The price of dysprosium oxide shot up nearly 60 percent in March, amid fears that prolonged unrest in Myanmar could tie up shipments of ores and concentrates.” As this feature in Mining Technology highlights, Tanzania can also soon emerge as a major supplier of very “high-grade neodymium praseodymium (NdPr) deposits in the world”. The neodymium supply, if it materialises, will be an important new source for building REE permanent magnets that are imperative to most modern systems civilian and military.An alternative source of REEs, apart from traditional mining methods, maybe urban mining, which is basically recycling REEs from scrapyards and garbage dumps containing REE rich e-waste. Until now, this hasn’t been a source of a significant amount of the world’s REE supply but as this article in Ars Technica points out over time it may emerge as a major source. If the content in this newsletter interests you, consider taking up the Takshashila GCPP in Technology Policy.

Proof of global surveillance exercised by the states has once again come to light, this time in the form of the Pegasus Project. It is a coordinated effort of Forbidden Stories, a French media non-profit, and Amnesty International. Eighty journalists from ten countries collaborated to unearth the global spying tool with the technical support of Amnesty’s Security Lab which conducted forensic tests to identify the traces of Israeli cybersecurity firm NSO’s spyware called Pegasus. Spyware is malicious software that enters a device, gathers data and transmits it to a server without the consent of the owner of the data. Pegasus is such a powerful cyber-surveillance tool that it is classified as a weapon and requires the same export clearances as a lethal weapon, explains Suhasini Haider, the Diplomatic Affairs Editor of The Hindu. Once injected into the target’s device, it can read messages and mails, access call logs and stored files, switch on and off the device, turn on the camera and microphone, and can even affect the devices near the targeted device, without the knowledge of the device owner. Until 2018, NSO relied on Enhanced Social Engineering Message (ESEM) i.e. a malicious SMS or a WhatsApp message to inject Pegasus into the target’s device. However, the latest version of Pegasus is a zero-click spyware i.e. spyware that does not need the target to click on any link or pick any calls. The target does not need to interact with the spyware. It can enter the target’s device merely by sending a push notification or by sending a missed call to the device. In 2016, Canadian Citizen Lab first flagged the cybersecurity threat presented by Pegasus to Apple. Then in 2019, WhatsApp blamed the NSO for exploiting a zero-day vulnerability in its video calling feature to inject spyware into users’ devices. Citizen Lab reported again in 2020 about governments using Pegasus to spy on journalists at Al Jazeera and Al Araby TV. Now, the Pegasus Project has reportedly revealed over fifty thousand targeted contact numbers which are mostly concentrated in Azerbaijan, Bahrain, India, Kazakhstan, Mexico, Morocco, Rwanda, Saudi Arabia, Hungary and the United Arab Emirates (UAE).State surveillance is not new. What is new is the ease of surveillance and the engagement of the private sector in mass surveillance. Also new is the Internet of Things (IoT), which could allow objects of daily use like cars and kitchen equipment to provide information about owners. It was with Edward Snowden’s revelations in 2013 that the world realized the omnipresence of the state in their daily lives. The symbiotic relationship between government spies and private companies has changed surveillance. Commercial corporations provide the technology, equipment as well as required information on citizens to government agencies in the form of online payment, searches, shopping, social media etc. What is also worth noticing in the case of Pegasus is the export of surveillance technologies from one country to another. NSO has maintained that the Israeli Minister of Defence has to approve NSO’s clients to make sure that the spyware is not used against Israel or its interests.I wonder if categorising nations as democratic or authoritarian has become archaic. We would do more justice to contemporary times if we compared governments on the basis of the mass surveillance they conduct on their own.Cyberpolitik #2: Digital Communication Networks and their harms-Prateek WaghreDigital Communication Networks (defined below) have led to concerns about rapid changes in the scale and structure of human networks, their impact on the quality of the information in circulation, and the role played by algorithms in directing the flow of information. Seventeen researchers have called for the study of collective behaviour to be elevated to a ‘crisis discipline’. A Takshashila Working Paper published earlier this week categorised the various harms attributed to Digital Communication Networks (DCNs). We define DCNs as composite entities consisting of the following components: Capability: Internet-based products/services that enable instantaneous low-cost or free communication across geographic, social, and cultural boundaries. This communication may be private (1:1), limited (1:n e.g. messaging groups), or broad (Twitter feeds, Facebook pages, YouTube videos, live streaming ), and so on. Operator(s): Firms/groups that design/operate these products and services. Networks: The entities/groups/individuals that adopt/use these products and services, and their interactions with each other. We did this because we felt existing terms such as ‘social media’, ‘big tech’, ‘digital platforms’, can be limited by context-dependence, or be too broad or too narrow. The proposed framing, we believe, encourages their study from the perspective of their effects on societies as a whole, rather than focussing on specific companies, technologies, sharing mechanisms, user dynamics, and other attributes which are constantly evolving.The paper classifies the harms attributed based on whether they have competitive, data-related or narrative effects.It then categorises these harms as potential market failures (3), social problems (13) and cognitive biases (9). The wide range of social problems and cognitive biases highlight the need for further study of the psychosocial effects of these harms and their broader impact in the Indian context. These considerations also raise the questions of how, and whether, the antitrust interventions currently being pursued in some of the developed economies will affect DCNs across competition, data and narrative spheres in the rest of the world.This is the first in a series of papers that will explore the different aspects of DCNs. Future work will investigate the benefits that DCNs enable, assess overlaps and contradictions between proposed or enacted DCN governance measures, and examine the role of global internet governance mechanisms.

American Resources Corporation (NASDAQ:AREC) CEO Mark Jensen tells Proactive that in conjunction with sponsored research partner Purdue University, the group has successfully achieved a high purity of the rare earth element (REE) — neodymium (Nd). Jensen says through the recycling of waste permanent magnets, it was able to separate, isolate, and purify the inherent neodymium to a 99.5% purity, a standard required for high-quality permanent magnet manufacturing.

Children the world over are fascinated with what can possibly “fit” in their orifices.  Diagnosis is often delayed.  Anxiety abounds before and during evaluation and management.     Most common objects:1,2 Food Coins Toys Insects Balls, marbles Balloons Magnets Crayon Hair accessories, bows Beads Pebbles Erasers Pen/marker caps Button batteries Plastic bags, packaging Non-pharmacologic techniques Set the scene and control the environment.  Limit the number of people in the room, the noise level, and minimize “cross-talk”.  The focus should be on engaging, calming, and distracting the child. Quiet room; calm parent; “burrito wrap”; guided imagery; have a willing parent restrain the child in his or her lap – an assistant can further restrain the head. Procedural Sedation Most foreign bodies in the ear, nose, and throat in children can be managed with non-pharmacologic techniques, topical aids, gentle patient protective restraint, and a quick hand.  Consider sedation in children with special health care needs who may not be able to cooperate and technically delicate extractions.  Ketamine is an excellent agent, as airway reflexes are maintained.3  Remember to plan, think ahead: where could the foreign body may be displaced if something goes wrong?  You may have taken away his protective gag reflex with sedation.  Position the child accordingly to prevent precipitous foreign body aspiration or occlusion. L’OREILLE – DAS OHR – вухо – THE EAR – LA OREJA – 耳 – L'ORECCHIO Essential anatomy: The external auditory canal. Foreign bodies may become lodged in the narrowing at the bony cartilaginous junction.4  The lateral 1/3 of the canal is flexible, while the medial 2/3 is fixed in the temporal bone – here is where many foreign bodies are lodged and/or where the clinician may find evidence of trauma.  Pearls: Ask yourself: is it graspable or non-graspable?5 Graspable: 64% success rate, 14% complication rate Non-graspable: 45% success rate, 70% complication rate5 If there is an insect in the external auditory canal, kill it first. They will fight for their lives if you try to dismember or take them out.  “In the heat of battle, the patient can become terrorized by the noise and pain and the instrument that you are using is likely to damage the ear canal.”5,6  Use lidocaine jelly (preferred), viscous lidocaine (2%), lidocaine solution (2 or 4%), isopropyl alcohol, or mineral oil. Vegetable matter? Don’t irrigate it – the organic material will swell against the fixed structure, and cause more pain, make it much harder to extract, and may increase the risk of infection. Pifalls: Failure to inspect after removal – is there something else in there? Failure to assess for abrasions, trauma, infection – if any break in skin, give prophylactic antibiotic ear drops Law of diminishing returns: probability of successful removal of ear foreign bodies declines dramatically after the first attempt   LE NEZ – DIE NASE – ніс – THE NOSE – LA NARIZ – 鼻 – IL NASO Essential anatomy: Nasopharyngeal and tracheal anatomy. Highlighted areas indicate points at which nasal foreign bodies may become lodged.4 Pearls: Consider using topical analgesics and vasoconstrictors to reduce pain and swelling – and improve tolerance of/cooperation with the procedure. Use 0.5% oxymetolazone (Afrin) spray and a few drops of 2 or 4%   Pros: as above.  Cons: possible posterior displacement of the foreign body.7 Be ready for the precipitous development of an airway foreign body Pitfalls: Beware of unilateral nasal discharge in a child – strongly consider retained foreign body.8 Do not push a foreign body down the back of a patient's throat, where it may be aspirated into the trachea. Be sure to inspect the palate for “vacuum effect”: small or flexible objects may be found on the roof of the mouth, just waiting to be aspirated.   LA GORGE – DER HALS – горло – THE THROAT – LA GARGANTA – 喉 – LA GOLA Before we go further – Remember that a foreign body in the mouth or throat can precipitously become a foreign body in the airway.  Foreign body inhalation is the most common cause of accidental death in children less than one year of age.9,10 Go to BLS maneuvers if the child decompensates. Infants under 1 year of age – back blows: head-down, 5 back-blows (between scapulae), 5 chest-thrusts (sternum).  Reassess, repeat as needed. Children 1 year and up, conscious – Heimlich maneuver: stand behind patient with arms positioned under the patient’s axilla and encircling the chest. The thumb side of one fist should be placed on the abdomen below the xiphoid process. The other hand should be placed over the fist, and 5 upward-inward thrusts should be performed. This maneuver should be repeated if the airway remains obstructed.  Alternatively, if patient is supine, open the airway, and if the object is readily visible, remove it.  Abdominal thrusts: place the heel of one hand below the xiphoid, interlace fingers, and use sharp, forceful thrusts to dislodge.  Be ready to perform CPR. Children 1 year and up, unconscious – CPR: start CPR with chest compressions (do not perform a pulse check). After 30 chest compressions, open the airway. If you see a foreign body, remove it but do not perform blind finger sweeps because they may push obstructing objects further into the pharynx and may damage the oropharynx.  Attempt to give 2 breaths and continue with cycles of chest compressions and ventilations until the object is expelled. Chest films are limited: 80% of airway foreign bodies are radiolucent.11  Look for unilateral hyperinflation on expiratory films: air trapping.  Essential anatomy: Most esophageal foreign bodies in children occur at the level of the thoracic inlet / cricopharyngeus muscle (upper esophageal sphincter).  Other anatomically narrow sites include the level of the aortic arch and the lower esophageal sphincter. Coin en face – in the esophagus – lodged at the thoracic inlet.12  The pliable esophagus accommodates the flat coin against the flat aspect of the vertebra.11 Beware the “double-ring” sign: this is a button battery13 This is an emergency: the electrolyte-rich mucosa conducts a focal current from the narrow negative terminal of the battery, rapidly causing burn, necrosis, and possibly perforation.  Emergent removal is required. Button batteries that have passed into the stomach do not require emergent intervention – they can be followed closely. Not a button battery, not a sharp object, not a long object? If there is no obstruction, consider revaluation the next day – may wait up to 24 hours for passage.14  Sharieff et al.15 found that coins found in the mid to distal esophagus within 24 hours all passed successfully. What conditions prompt urgent removal? Size Infants: objects smaller than 2 cm wide and 3 cm long will likely pass the pylorus and ileocecal valve10 Children and adults: objects smaller than 2 cm wide and 5 cm long will likely pass the pylorus and ileocecal valve9 Character Sharp objects have a high rate of perforation (35%)1 Pearls: History is essential. Believe the parents and assume there is an aspirated/ingested foreign body until proven otherwise. History of choking, has persistent symptoms and/or abnormal xray? Broncoscopy! Cohen et al.16 found that of 142 patients evaluated at a single site university hospital, 61 had a foreign body. Of the 61 patients, 42 had abnormal physical exams and radiographs and 17 had either abnormal physical exams or radiographs, and 2 had normal physical exams and radiographs, but both had a history of persistent cough.  Bottom line: history of choking PLUS abnormal exam, abnormal films, or persistent symptoms, evaluate with bronchoscopy. For patients with some residual suspicion of an aspirated foreign body (mild initial or improving symptoms; possibly abnormal chest x-ray; low but finite risk), consider chest CT with virtual bronchoscopy as a rule-out strategy.17,18 Outpatients who have passed a small and non-concerning object into the stomach or beyond: serial exams and observing stools – polyethylene glycol 3350 (MiraLAX) may be given for delayed passage19 Pifalls: A single household magnet will likely pass through the GI tract, with the aforementioned dimensional caveats. Two or more magnets, however, run the risk of attraction and trans-bowel wall pressure necrosis. Not all magnets are created equal. Neodymium magnet toys (“buckyballs”) were recalled in 2014 (but are still out there!) due to their highly attractive nature.  These magnets must be removed to avoid bowel wall ischemia. 19–21 Patients should avoid wearing belt buckles or metallic buttons in case of single magnet ingestion while waiting for the single magnet to pass DES OUTILS DU MÉTIER – DIE HANDWERKSZEUG – Знаряддя праці – TOOLS OF THE TRADE – LAS HERRAMIENTAS DEL OFICIO – GLI ATTREZZI DEL MESTIERE –  仕事のツール It’s best to keep your armamentarium as large as you can.   Curette A small foreign body in the lateral 1/3 of the auditory canal may be amenable to a simple curettage.  Hair beads (if the central hole is accessible) may be manipulated out with the angled tip of a rigid curette.  Steady the operating hand by placing your hypothenar eminence on the child’s zygoma or temporal scalp, to avoid jutting the instrument into the ear canal with sudden movement.  There is a large selection of disposable simple and lighted curettes on the market. Right-angle Hook Various eponymous hooks are available for this purpose; one in popular use is the Day hook, which may be passed behind the foreign body.22  An inexpensive and convenient alternative to the commercially available right-hooks is a home-made version: make your own by straightening out a paperclip and bending it to a right angle23 at 2-3 mm from the end (be sure not to use the type that have a friable shiny metallic finish, as the residue may be left behind in the ear canal).  If it is completely lodged, use of a right-angle hook will likely only cause trauma to the canal. Alligator forceps Alligator forceps are best for grasping soft objects like cotton or paper.  Smooth, round or oval objects are not amenable to extraction with alligator forceps.  When using them, be sure to get a firm, central grip on the object, to avoid tearing it into smaller, less manageable pieces.  Pro tip: Look before you grip! Be careful to visualize the area you are gripping, to avoid pulling on (and subsequently avulsing) soft tissue in the ear canal. Cyanoacrylate (Dermabond®, SurgiSeal®) Apply cyanoacrylate to either side of a long wooden cotton swab (the lecturer prefers the cotton tip side, for improved grip/molding around object).  Immediately apply the treated side to the object in the ear canal in a restrained patient.  Steady the hypothenar eminence on the child’s face to avoid dislodgement of the cotton swab with sudden movement.  Apply the treated swab to the foreign body for 30-60 seconds, to allow bonding.  Slowly pull out the foreign body.  Re-visualize the ear canal for other retained foreign bodies and abrasion or ear canal trauma. Did the cyanoacrylate drip?  Did the swab stick to the ear canal? No problem – use 3% hydrogen peroxide or acetone.24  Pour in a sufficient amount, allow to work for 10 minutes.  Both agents help to dissolve ear wax, the compound, or both.  Repeat if needed to debond the cyanoacrylate from the ear canal.24,25 Irrigation Irrigation is the default for non-organic foreign bodies that are not amenable to other extraction techniques.  Sometimes the object is encased in cerumen, and the only “instrument” that will fit behind the foreign body is the slowly growing trickle of water that builds enough pressure to expulse it.  Do not use if there is any organic material involved: the object will swell, causing much more pain, difficulty in extraction, and possibly setting up conditions for infection. Position the child either prone or supine, gently restrain (as above).  Let gravity work for you: don’t irrigate in decubitus position with the affected ear up.  It may be more accessible to you, but you may never get the foreign body out. To use a butterfly needle: use a small gage (22 or 24 g) butterfly set up, cut off the needle, connect the tubing to a 30 mL syringe filled with warm or room-temperature water. Insert the free end of the tubing gently, and “secure” the tubing with your pinched fingers while irrigating (think of holding an ETT in place just after intubation and before taping/securing the tube).  Gently and slowly increase the pressure you exert as you irrigate. To use an IV or angiocatheter: use a moderate size (18 or 20 g) IV, remove the needle and attach the plastic catheter to a 20 mL syringe, and irrigate as above. Acetone Acetone has been used successfully to remove chewing gum, Styrofoam, and superglue from the ear canal24,26,27  Use in cases where there is no suspicion of perforation of the tympanic membrane. Docusate Sodium (Colace®) Cerumen is composed of sebaceous ad ceruminous secretions and desquamated skin.  Genetic, environmental, and anatomical factors combine to trap a foreign body in the external canal.  Use of a ceruminolytic such as docusate sodium may help to loosen and liberate the foreign body.28  Caveat medicus: Adding docusate sodium will make the object more slippery – this may or may not be an issue given the nature of the foreign body. In the case where loosening the ear wax may aid extraction (and will not cause a slippery mess), consider filling the ear canal will docusate sodium (Colace), having the child lie with the affected side up, waiting 15 minutes, and proceeding.  This is especially helpful when planning for irrigation. Magnets Rare earth magnets (a misnomer, as their components are actually abundant) such as neodymium can be useful in retrieving metallic foreign bodies (e.g. button batteries in the nose or ears).29,30  Magnetic “pick-up tools” – used by mechanics, engineers, and do-it-yourselfers – are inexpensive and readily available in various sizes, shapes, and styles such as a telescoping extender.  Look for a small tip diameter (to fit in the ear canal as well as the nose) and a strong “hold” (at least a 3-lb hold). Alternatively, you may purchase a strong neodymium bar magnet (30- to 50-lb hold) to attach to an instrument such as an alligator forceps, pick-up forceps, or small hemostat (a pacemaker magnet may also work).  The magnetic bar, placed in your palm at the base of the instrument, will conduct the charge (depending on the instrument) and allow you to retrieve many metallic objects.31  Although stainless steel is often said to be “non-magnetic”, it depends on the alloy used, and some may actually respond to the strong rare earth magnet.  Most stainless steel has a minimum of 10.5% chromium, which gives the steel its 'stainless' properties (essentially corrosion resistance).  A basic stainless steel has a “ferritic” structure and is magnetic.  Higher-end stainless steel such as in kitchen cutlery have an “austenitic” structure, with more chromium added, and so less magnetic quality.  (Ironically, the more “economical” instruments in the typical ED suture kit have less chromium, and so are more magnetic – use these with your neodymium bar magnet to conduct the magnetic charge and extract the metallic foreign body.) Bottom line: if it’s metal, it’s worth a try to use a magnet.  Even if the metal is very weakly magnetic, the strong neodymium magnet may still be able to exert a pull on it and aid in extraction. Snare Technique A relatively new method, described by Fundakowski et al.32 consists of using a small length of 24-gauge (or similar) wire (available inexpensively online, and kept in your personal “toolkit”; see Appendix B below) to make a loop that is secured by a hemostat (the 24-gauge wire is easily cut into strips with standard trauma scissors).  After treatment with oxymetolazone (0.05%) and lidocaine (1 or 2%) topically, the loop is passed behind the foreign body (in the case report, a button battery).  Pull the loop toward you until you feel that it is sitting up against the button battery.  Now, turn the hemostat 90° to improve your purchase on the foreign body.  Pull gently out.  This technique is especially useful when the foreign body has created marked edema, either creating a vacuum effect or making it difficult for other instruments to pass. Balloon Catheters (Katz extractor®, Fogarty embolectomy catheter) Small-caliber devices (5, 6, or 8 F) originally designed for use with intravascular or bladder catheterization may be used to extract foreign bodies from the ear or nose.7,33  A catheter designed specifically for foreign body use is the Katz extractor.  Inspect the ear or nose for potential trauma and to anticipate bleeding after manipulation (especially the nose).  Deflate the catheter and apply surgical lubricant or 2% lidocaine jelly. Insert the deflated catheter and gently pass the device past the foreign body.  Inflate the balloon and slowly pull the balloon and foreign body out.  Re-inspect after extraction. NB, from the manufacturer of the Katz extractor, InHealth: “the Katz Extractor oto-rhino foreign body remover is intended principally for extraction of impacted foreign bodies in the nasal passages. This device may also be used in the external ear canal, based upon clinical judgment.” Mother’s kiss The mother’s kiss was first described in 1965 by Vladimir Ctibor, a general practitioner from New Jersey.34 “The mother, or other trusted adult, places her mouth over the child’s open mouth, forming a firm seal as if about to perform mouth-to-mouth resuscitation. While occluding the unaffected nostril with a finger, the adult then blows until feeling resistance caused by closure of the child’s glottis, at which point the adult gives a sharp exhalation to deliver a short puff of air into the child’s mouth. This puff of air passes through the nasopharynx, out through the non-occluded nostril and, if successful, results in the expulsion of the foreign body. The procedure is fully explained to the adult before starting, and the child is told that the parent will give him or her a “big kiss” so that minimal distress is caused to the child. The procedure can be repeated a number of times if not initially successful.”34 Positive Pressure Ventilation with Bag Valve Mask This technique is an approximation of the above mother’s kiss technique – useful for unwilling parents or unsuccessful tries.10,25  The author prefers to position the child sitting up.  A self-inflating bag-mask device is fitted with a very small mask: use an abnormally small mask (otherwise inappropriately small for usual resuscitative bag-mask ventilation) to fit over the mouth only.  Choose an infant mask that will cover the child’s mouth only.  Occlude the opposite nostril with your finger while you form a tight seal with the mask around the mouth. Deliver short, abrupt bursts of ventilation through the mouth – be sure to maintain good seals with the mask and with your finger to the child’s nostril – until the foreign body is expulsed through the affected nostril. Beamsley Blaster (Continuous Positive Pressure) Technique For the very uncooperative child with a nasal foreign body amenable to positive pressure ventilation who fails the mother’s kiss and bag-mask technique, a continuous positive pressure method may be used. Connect one end of suction tubing to the male adaptor (“Christmas tree”) of an air or oxygen source.  Connect the other end of the suction tubing to a male-to-male adaptor (commonly used for chest tube connections or connecting / extending suction tubes).  Insert the end of the device into the child’s unaffected nostril.  The air flow will deliver positive pressure ventilation continuously. With this technique there is a theoretical risk of barotrauma to the lungs or tympanic membranes.  However, there is only one case reported in the literature of periorbital subcutaneous emphysema. To minimize this risk, some authors recommend limiting to a maximum of four attempts using any positive pressure method.10 Nasal speculum Optimize your visualization with a nasal speculum.  The nostrils, luckily, will accommodate a fair amount of distention without damage.  Hold the speculum vertically to avoid pressure on and damage to the vessel-and-nerve-rich nasal septum.  Hold the handle of the speculum in the palm of your hand comfortably and while placing your index finger on the patient’s ala.  This will help to control the speculum and your angle of sight. Your other hand is then free to use a hook or other tool for extraction. Lighting is especially important when using the nasal speculum: a focused procedure light or head lamp is very helpful.  The author keeps a common camping LED headlamp in his bag for easy access. Suction tips / catheters Various commercial and non-commercial suction devices are on the market for removal of foreign bodies.  All connect to wall suction, and vary by style, caliber of suction, and tip end interface.  A commonly available suction catheter is the Frazier suction tip (right), a single-use device used in the operating room. A modification to suction can be made with the Schuknecht foreign body remover (left; not to be confused with the suction catheter of the same name): a plastic cone-shaped tip placed on the end of the suction catheter to increase vacuum surface area and seal.  Laryngoscope and Magill Forceps If a child aspirates and occludes his airway, return to BLS maneuvers (as above).  If the child becomes obtunded, use direct laryngoscopy to visualize the foreign body and remove with the Magill forceps.  Hold the laryngoscope in your left hand as per usual.  Hold the Magill forceps in your right hand – palm side down – to grasp and remove the foreign body.  Take-home Points  Beware the “vacuum palate”: a flat (especially clear plastic) foreign body hiding on the palate Take seriously the complaint of foreign body without obvious evidence on initial inspection – believe that something is in there until proven otherwise Control the environment, address analgesia and anxiolysis, have a back-up plan Motto Like a difficult airway: plan through the steps MERCI – DANKE – Дякую – THANK YOU – GRACIAS –  ありがとう— GRAZIE Appendix A: Prevention At the end of the visit, after some rapport has been established, counsel the caregivers about age-appropriate foods and “child-proofing” the home.  This is a teachable moment – and only you can have this golden opportunity! Age-appropriate foods 0-6 months: breastmilk or formula 6-9 months: introduce solid puree-consistency foods 9-12 months: small minced solids that require no chewing (well cooked, soft, chopped foods) Although molars (required for chewing) erupt around 18 months, toddlers need to develop coordination, awareness to eat hard foods that require considerable chewing. Not until 4 years of age (anything that requires chewing to swallow):             Hot dogs             Nuts and seeds             Chunks of meat or cheese             Whole grapes             Hard or sticky candy             Popcorn             Chunks of peanut butter             Chunks of raw vegetables             Chewing gum Child-proofing the home Refer parents to the helpful multi-lingual site from the American Academy of Pediatrics: http://www.healthychildren.org/English/safety-prevention/at-home/Pages/Childproofing-Your-Home.aspx An abbreviated list: use age-appropriate toys and “test” them out before giving them to your child to verify that there are no small, missing, or loose parts.  Secure medications, lock up cabinets (especially with chemicals), do not store chemicals in food containers, secure the toilet bowl, and unplug appliances. Parents should understand that “watching” their child alone cannot prevent foreign body aspiration: a recent review found that in 84.2% of cases, incidents resulting in an airway foreign body occurred in the presence of an adult.35 Best overall tip: get down on all fours and inspect your living area from the child’s perspective.  It is amazing what you will find when you are least expecting it. Appendix B: The Playbook's ENT Foreign Body Toolkit Although your institution should supply you with what you need to deal with routine problems, we all struggle with having just what we need when we need it.  High-volume disposable items such as cyanoacrylate (Dermabond), curettes, supplies for irrigation, alligator forceps, and the like certainly should be supplied by the institution.  However, some things come in very handy as our back-up tools. NB: we should be cognizant of the fact that tools that must be sterilized or autoclaved are not good candidates for our personal re-usable toolkits. These items can all be found inexpensively – shop around online, or in home improvement stores: Head lamp, LED camping style: $5-15 Neodymium magnet “pick-up tool”: $5-15 Neodymium bar magnet: $6-20 Wire, 24-gauge, spool of 25 yards (for snare technique): $6 Day hook: $15-20 References Chapin MM, Rochette LM, Annest JL, Haileyesus T, Conner KA, Smith GA.
