Wound complications can be devastating following total joint arthroplasty, resulting in an increased practice burden in the form of more frequent follow ups, increased clinic visits potential for wound dehiscence, superficial infection and deep infection with possible return to the operating room and revision surgery. Several dressing options are currently on the market designed to minimize wound complications in addition to traditional dressings, including negative pressure dressing, antimicrobial dressing, occlusive dressings, and/or skin adhesives. Prineo dressing (2-octyl cyanoacrylate adhesive (Dermabond) and n-butyl-2-cyanoacrylate adhesive) has increased in popularity as a dressing option used by joint arthroplasty surgeons. There is a well-documented adverse allergic response with these dressings resulting in peri-incisional erythema, urticaria, and/or an eczematous skin reaction. Recently, Mayman et al reported a rate of 1-1.5%, suggesting a possible rising incidence of ACD attributable to increased utilization of the specific dressing and sensitization. To our knowledge, no prospective trial has compared the rates of adverse allergic reactions in Prineo naive patients to patients who have undergone previous total joint arthroplasty (TJA) and received Prineo dressings in the past. The study team will utilize a prospective controlled study design to assess the rate of adverse allergic reactions in patients naive to Prineo versus those with previous exposure. The study team will assess rates of allergic reactions at one week post-op and at their first post-op clinic visit, 2 to 3 weeks post-op, tracking rates of allergic reactions as well as severity, the use of post-operative antibiotics, work up for prosthetic joint infection, return to the operating room, surgical site infection, confirmed prosthetic joint infection and stiffness requiring manipulation under anesthesia.
The study will only involve identification of the listed allergies from the electronic medical record and investigation into the symptoms that prompted this allergy listing. The purpose is to evaluate demographics and prevalence of allergies in patients presenting for surgery, evaluate the medical decision making process behind allergy identification, and determine its potential impact on perioperative care. The participants will be asked to complete a survey in REDCap using an iPad during the visit.
The study will systematically evaluate how an emergency manual-a collection of checklists and fact sheets-affects the performance of resuscitation teams during the management of priority one patients in an emergency department.
Antibiotic prophylaxis in the operating room reduces the frequency of occurrence of surgical site infections (SSI) by preventing bacterial proliferation. The main antibiotic used in all surgery is CEFAZOLINE. This antibiotic of the Beta-lactam family, and more precisely of the 1st generation cephalosporins, is active on a specific bacterial target, which is often the cause of surgical site infections. Patients known to be allergic to penicillin have a 50% higher risk of surgical site infection. The choice of antibiotic prophylaxis often comes up against the risk of allergy in anesthesia. In France in 2004, according to the INSERM database, 100 IgE-mediated immediate hypersensitivity reactions (IHR) were observed out of 1 million anesthesias. The attributable allergens in descending order were curares (60.6%), latex (5.2%) then antibiotics (18.2%), followed by dyes (3.5%), hypnotics, opioids, gelatins and local anesthetics were rarely found. Regarding allergy to antibiotics, the leading antibiotic for allergy in France is AMOXICILLIN, which accounts for 29% of drug-induced anaphylaxis. In view of the risk of cross-allergy, a history of allergy to AMOXICILLIN in the operating room is a contraindication to all beta-lactam antibiotics and therefore leads to an alternative choice to CEFAZOLINE when the latter was indicated for first-line antibiotic prophylaxis. However, this choice of alternative antibiotic to CEFAZOLINE is not without consequences. First of all, the alternative antibiotics Vancomycin and Clindamycin have a narrower spectrum and therefore may not cover all germs found in SSI. They do not cover Gram-negative organisms for Vancomycin and Gram-negative aerobes for Clindamycin. Moreover, the use of these antibiotics exposes to undesirable effects. They can promote the occurrence of nosocomial infections such as Clostridium difficile colitis, infections with resistant germs such as methicillin-resistant Staphylococcus aureus (MRSA) or Vancomycin-resistant Enterococcus (VRE). Other adverse effects may occur such as Nephrotoxicity and Red Man Syndrome with Vancomycin. In addition, these antibiotics may be more difficult to handle, not allowing for the optimization of recommended delivery conditions. Secondly, the notion of the cost of these antibiotics must be taken into account. Two elements could encourage investigators to use CEFAZOLINE despite a history of allergy to AMOXICILLIN. 1. 1. Allergy declarations such as can be obtained in consultation correspond mainly to false positives. In fact, out of 10% of the world's population reporting an allergy to penicillins, only 1 to 2% of subjects have a proven allergy. In GHPSJ, among the patients consulting for a suspected allergy, the reintroduction test confirmed it in only 5.6% of them. 2. From a molecular point of view, there is a low rate of similarity between these two molecules. Contrary to popular belief, cephalosporin allergy is not mediated by the β-lactam core. The cross-allergy between cephalosporins and penicillin comes from the similarities of the R1 chain which is attached to the β-lactam nucleus at position 7 for cephalosporins, at position 6 for penicillins. This may therefore explain the lack of clinical cross-reactivity. The primary objective is to evaluate the proportion of patients of allergies between CEFAZOLINE and AMOXICILLINE. The secondary objectives are to evaluate the diagnostic value of skin tests to CEFAZOLINE and to describe the safety of protocol of reintroduction of CEFAZOLINE and AMOXICILLINE in the context of IgE-mediated cross-reactivity.
The objective of this study is to determine the biological activity of Juniperus oxycedrus and Cupressus arizonica. allergen extracts in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
The objective of this study is to determine the biological activity of Quercus illex and Quercus robur allergen extracts in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
By achieving effective cooperation between the Children's Hospital Srebrnjak (CHS), the Reference center for clinical allergology in children of the ministry of health, and IN2 Ltd., part of Constellation Software Inc., it is planned to develop an IT platform for the introduction of personalized balanced nutrition in kindergartens. The collected data which include the screening of the population, anthropometrical measurements, physical activity status, and medical examination, will be used to create a Registry of Allergies. Through the implementation of research activities, it is expected to develop an IT platform for personalized balanced nutrition of preschool children, which consists of a developed information system for continuous monitoring using a website and/or a mobile application.
Background: While medical advances for in-hospital care rapidly evolve, a mainstay of effective pre-hospital care remains the ability to treat medical emergencies such as anaphylaxis, prolonged seizure, overdose, or uncontrolled bleeding, through rapid administration of appropriate medication. Autoinjectors are used globally to deliver medications in a timely manner, often in environments where immediate access to medical facilities is limited. Rapid administration of intramuscular medication delivery is essential where oral or intravenous delivery is either not possible or ineffective. The purpose of the proposed study seeks to determine the efficiency various types of medication injection administration.
The investigators hypothesize gold is inert and thereby there is no pure-gold allergy. The primary aim of this study is to measure the prevalence of allergy to metallic pure gold microparticles and allergy to GSTS.
