What Chamber Operators Should Know About Ear Barotrauma (And How to Prevent It) Robert Sheffield, CHT and Kevin “Kip” Posey, CHT / June 2018
LEARN.HYPERBARICMEDICINE.COM International ATMO Education What Chamber Operators Should Know About Ear Barotrauma (and How to Prevent It) Robert Sheffield, CHT and Kevin “Kip” Posey, CHT / June 2018 INTRODUCTION Ear barotrauma (i.e. “ear block”, “ear squeeze”) is the most common complication of hyperbaric treatment. It occurs when the pressure in the hyperbaric chamber is greater than the pressure in the middle ear. It is prevented by patient assessment, patient education, and the appropriate actions of the chamber operator. The chamber operator has an important role in preventing ear barotrauma in hyperbaric patients. OBJECTIVES At the conclusion of this article, the reader will be able to: Describe the anatomy of the middle ear Explain the mechanism of ear barotrauma Describe 3 techniques to equalize middle ear pressure ANATOMY OF THE MIDDLE EAR The middle ear is an air space that separates the external ear canal from the inner ear. The eardrum, called the tympanic membrane (TM), vibrates when sound enters the ear canal. The vibration is transmitted to a series of bones in the middle ear. These bones transmit vibration to another membrane (the oval window) that separates the air‐filled middle ear from the fluid‐filled inner ear, where sound is sensed in the cochlea. The nasopharynx is the area behind the nose and above the palate. The Eustachian tubes open into this area. Because of the location of the Eustachian tube openings, the same things that cause nasal congestion (e.g. allergies, upper respiratory infection) can cause swelling around the opening of the Eustachian tubes, making it more difficult to equalize pressure in the middle ear. -

Internal Medicine, Khyber Teaching Hospital, Peshawar, PAK Corresponding author: Deepika Sarvepalli, [email protected] Abstract Alemtuzumab, a humanized monoclonal antibody that targets surface molecule CD52, causes rapid and complete depletion of circulating T- and B-lymphocytes through antibody-dependent cell-mediated and complement-mediated cytotoxicity. Alemtuzumab has demonstrated superior efficacy compared to subcutaneous interferon beta-1a (SC IFNB-1a) in patients with multiple sclerosis (MS). Alemtuzumab treatment causes a rare and distinct form of secondary immune thrombocytopenic purpura (ITP), characterized by delayed onset, responsiveness to conventional therapies, and prolonged remission following treatment. In phase two and three clinical trials, the incidence of ITP was higher with alemtuzumab treatment compared to the patients receiving SC IFNB-1a. Here we report a case of ITP occurring two years after the first treatment with alemtuzumab. The patient recovered completely after a timely diagnosis -
Bruise, Contusion & Ecchymosis Conventions
Bruise, Contusion and Ecchymosis MedDRA Proactivity Proposal Implementation MedDRA Version 16.0 I. MSSO Recognized Definitions of Concepts and Terms The MSSO has designated Dorland’s Illustrated Medical Dictionary as the standard reference for medical definitions. The following definitions are cited from Dorland’s 27th edition: Bruise – A superficial injury produced by impact without laceration; a contusion Contusion – A bruise; an injury of a part without a break in the skin Ecchymosis – A small hemorrhagic spot, larger than a petechia, in the skin or mucous membrane forming a nonelevated, rounded or irregular, blue or purplish patch. Hematoma – A localized collection of blood, usually clotted, in an organ, space, or tissue, due to a break in the wall of a blood vessel. Hemorrhage – The escape of blood from the vessels; bleeding. Petechia – A pinpoint, non-raised, perfectly round, purplish red spot caused by intradermal or submucous hemorrhage. Additional comments regarding the definitions: Bruise and contusion are synonymous, and are often used in a colloquial context. Bruise and contusion are each considered a result of injury. Bruise and contusion have been used to describe minor hemorrhage within tissue, where traumatized blood vessels leak blood into the interstitial space. Commonly, capillaries and sometimes venules are injured within skin, subcutaneous tissue, muscle, or bone. In addition to trauma, the terms bruise, ecchymosis, and to a lesser extent, contusion, have also been used as clinical signs of disorders of platelet function, coagulopathies, venous congestion, allergic reactions, etc. Hemorrhage may be used to describe blood escaping from vessels and retained in the interstitial space, and perhaps more commonly, to describe the escape of blood from vessels, and flowing freely external to the tissues. -

AstraZeneca AB in agreement with the European Medicines Agency and the Health Products Regulatory Authority (HPRA) would like to inform you of the following: Summary Vaxzevria is contraindicated in individuals who have experienced Thrombosis with Thrombocytopenia Syndrome (TTS) following previous vaccination with Vaxzevria. TTS requires specialised clinical management. Healthcare professionals should consult applicable guidance and/or consult specialists (e.g., haematologists, specialists in coagulation) to diagnose and treat this condition. Individuals diagnosed with thrombocytopenia within 3 weeks after vaccination with Vaxzevria should be actively investigated for signs of thrombosis. Similarly, individuals who present with thrombosis within 3 weeks of vaccination should be evaluated for thrombocytopenia. The Vaxzevria Summary of Product Characteristics (SmPC) has been updated accordingly with this information. Background on the safety concern Vaxzevria is indicated for active immunisation to prevent COVID-19 caused by SARS-CoV-2, in individuals 18 years of age and older. A combination of thrombosis and thrombocytopenia, in some cases accompanied by bleeding, has been observed very rarely following vaccination with Vaxzevria.

However, due to a low overall incidence, it may go undiagnosed. Case Report: A 56-year-old man with a medical history of right upper lobectomy due to lung cancer showed changes in mental status after the Valsalva maneuver, followed by status epilepticus during admission. Brain and chest computed tomography showed cerebral air embolism and accidental pneumothorax in the right major fissure. After antiepileptic drug infusion and oxygen therapy, he recov- ered completely. Conclusion: Since cerebral air embolism may result in fatal outcomes, it should be suspected in patients with sudden neurological de- terioration after routine medical procedures.

DOI: 10.5935/0946-5448.20120032 ORIGINAL ARTICLE International Tinnitus Journal. 2012;17(2):180-5. Middle ear barotrauma after hyperbaric oxygen therapy - the role of insuflation maneuvers Marco Antônio Rios Lima1 Luciano Farage2 Maria Cristina Lancia Cury3 Fayez Bahmad Jr.4 Abstract Objective: To analyze the association of insuflation maneuvers status before hyperbaric oxygen therapy with middle ear barotrauma. Materials and Methods: Fouty-one patients (82 ears) admitted to the Department of Hyperbaric Medicine from May 2011 to July 2012. Assessments occurred: before and after the first session, after sessions with symptoms. During the evaluations were performed: otoscopy with Valsalva and Toynbee maneuvers, video otoscopy and specific questionnaire. Middle ear barotrauma was graduated by the modified Edmond’s scale. Tubal insuflation was classified in Good, Median and Bad according to combined results of Valsalva and Toynbee maneuvers. Inclusion criteria: patients evaluated by an otolaryngologist before and after the first session, with no history of ear disease, who agreed to participate in the research (convenience sample). Results: Of the 82 ears included in the study, 32 (39%) had barotrauma after the first session. The rate of middle ear barotrauma according to tubal insuflation was: 17.9% (Good insuflation) 44.4% (Median insuflation) and 55.6% (Bad insuflation)P ( = 0.013). Conclusion: Positive Valsalva and Toynbee maneuvers before the first session, alone or associated were protective factors for middle ear barotrauma by ear after the first session. Keywords: barotrauma, hyperbaric oxygenation, middle ear ventilation. 1 Health Science School - University of Brasília - Brasília - DF - Brasil.

Abstract Hemothorax is defined as a bleeding into pleural cavity. Hemothorax is a frequent manifestation of blunt chest trauma. Some authors suggested a hematocrit value more than 50% for differentiation of a hemothorax from a sanguineous pleural effusion. Hemothorax is also often associated with penetrating chest injury or chest wall blunt chest wall trauma with skeletal injury. Much less common, it may be related to pleural diseases, induced iatrogenic or develop spontaneously. In the vast majority of blunt and penetrating trauma cases, hemothoraces can be managed by relatively simple means in the course of care.

Thrombocytopenia in the Canine Patient Shana O'marra, DVM, DACVECC Dovelewis Annual Conference Speaker Notes
Thrombocytopenia in the Canine Patient Shana O'Marra, DVM, DACVECC DoveLewis Annual Conference Speaker Notes Identifying Thrombocytopenia Clinical signs: Petechia, ecchymoses, gingival bleeding, scleral hemorrhage, hyphema, epistaxis, hematuria and melena are common. Depending on degree of blood loss, the patient may also display signs of anemia or hypovolemia such as tachycardia or weakness. Many patients have no outward manifestations despite thrombocytopenia. Spontaneous bleeding occurs only with severe thrombocytopenia (<35,000plt/µL) unless platelet dysfunction or concurrent coagulopathies are present. Platelet count: Difficult or prolonged venipuncture can lead to platelet clumping or even macroscopic blood clot formation. Blood samples should be immediately transferred into an EDTA containing blood tube. All automated platelet counts should be confirmed with a manual blood film. An estimated platelet count is calculated by averaging the platelets in the monolayer in ten fields at 100x (oil), and multiplying by 15,000. Pseudothrombocytopenia: In 0.1% of humans, EDTA induces persistent platelet clumping. In the presence of EDTA, previously hidden platelet surface antigens are exposed, allowing antibody-mediated platelet aggregation to occur. Because the antigens are not available on the platelet surface in the absence of EDTA, this is a strictly in vitro phenomenon. Anticoagulation with citrate can give more accurate platelet counts in these patients, but can alter platelet indices and lead to more platelet clumping in normal patients, so EDTA remains the anticoagulant of choice for routine evaluation. Breed variations in platelet count: 30-50% of Cavalier King Charles Spaniels have a beta tubulin mutation causing macrothrombocytopenia. A similar mutation has been described in Norfolk and Cairn Terriers, and asymptomatic macrothrombocytopenia has been reported in a Beagle.
