Infection Control in Dentistry: How to Asepsis Photographic Mirrors?
Infection control in dentistry: how to asepsis photographic mirrors? Amanda Osório Ayres de Freitas* Mariana Marquezan* Giselle Naback Lemes Vilani* Rodrigo César Santiago* Luiz Felipe de Miranda Costa* Sandra Regina Torres** Abstract: The aim of this study was to evaluate the efficacy of six different methods of disinfection and sterilization of intraoral photographic mirrors through microbiological testing and to analysis their potential harm to mirrors’ surface. Fourteen occlusal mirrors were divided into seven groups. Group 1 comprised two mirrors as received from manufacturer. The other six groups comprised mirrors disinfected/sterilized by autoclave, immersion in enzymatic detergent, and friction with chlorhexidine detergent, chlorhexidine wipes, common detergent and 70% ethylic alcohol. Microbiological and quality surface analyses were performed. Sterilization in autoclave was microbiologic effective, but caused damage to the mirror surface. Chlorhexidine (in wipes or detergent) and liquid soap were effective disinfectant agents for photographic mirrors decontamination, without harmful effect on its surface. Enzymatic detergent immersion and friction with 70% ethylic alcohol were not effective as disinfectant agents for photographic mirrors decontamination. According to the results, the more effective and safe methods for photographic mirrors disinfection were friction with chlorhexidine wipes or detergent, as well as liquid soap. Results, the most efficacious methods for photographic mirrors disinfection were friction with chlorhexidine wipes and detergent, as well as common detergent.

Puerperal septicemia, commonly called childbed fever, was the culprit, and nobody in the world’s medical or scientific community at the time knew how to control its epidemic proportions. -

Role of the Microbiology Laboratory in Infection Control
GUIDE TO INFECTION CONTROL IN THE HOSPITAL CHAPTER 3: Role of the Microbiology Laboratory in Infection Control Author Mohamed Benbachir, PhD Chapter Editor Gonzalo Bearman MD, MPH, FACP, FSHEA, FIDSA Topic Outline Key Issues Known Facts Suggested Practice Suggested Practice in Under-Resourced Settings Summary References Chapter last updated: January, 2018 KEY ISSUES The microbiology laboratory plays an important role in the surveillance, treatment, control and prevention oF nosocomial inFections. The microbiologist is a permanent and active member oF the infection control committee (ICC) and the antimicrobial stewardship group (ASG). Since most of the inFection control and antimicrobial stewardship programs rely on microbiological results, quality assurance is an important issue. KNOWN FACTS The microbiologist is a daily privileged interlocutor oF the infection control team (inFection control doctor and inFection control nurse) and the antimicrobial stewardship working group. The First task oF the microbiology laboratory is to accurately, consistently and rapidly identiFy the responsible agents to species level and identify their antimicrobial resistance patterns. Traditional microbiologic methods remain suboptimal in providing rapid identification and susceptibility testing. There is a growing need for more rapid and reliable laboratory results. Important progress made in the fields of instruments, reagents and techniques have made it easier to adapt to the important changes oF the clinical microbiology context e.g. increasing use of microbiology tests, shortage of qualiFied personnel. There is also a growing demand For quality in clinical laboratories and more and more countries are elaborating national regulations. 1 The microbiology processes are becoming increasingly more complex. InFormatics are playing an increasing role in the improvement oF these processes in terms oF workFlow, timeliness and cost. -

It can be a challenging differential diagnosis in dermatology practice due to several overlapping features with rheumatologic disorders. Patients with leprosy can develop reactive states as a result of immune complex-mediated inflammatory processes, leading to the appearance of additional cutaneous lesions that may further complicate the clinical picture. We describe a case of a woman presenting with a long history of a recurrent bullous rash with chronic ulcers, with an evolution of vasculitic diagnoses, who was later determined to have lepromatous leprosy with reactive erythema nodosum leprosum (ENL). Introduction accompanied by an intense bullous purpuric rash on management of sepsis secondary to bacteremia, Leprosy is a slowly progressive disease caused by bilateral arms and face. For these complaints she was with lower-extremity cellulitis as the suspected infection with Mycobacterium leprae (M. leprae). seen in a Complex Medical Dermatology Clinic and source.

Paper 1 Medicine Key topics 1 and 2 (1250-1500, 1500-1700) Year 11 GCSE History Paper 1 – Medicine Information booklet Medieval Renaissance 1250-1500 1500-1750 Enlightenment Modern 1900-present 1700-1900 Case study: WW1 1 Paper 1 Medicine Key topics 1 and 2 (1250-1500, 1500-1700) Key topic 1.1 – Causes of disease 1250-1500 At this time there were four main ideas to explain why someone might become ill. Religious reasons - The Church was very powerful at this time. People would attend church 2/3 times a week and nuns and monks would care for people if they became ill. The Church told people that the Devil could infect people with disease and the only way to get better was to pray to God. The Church also told people that God could give you a disease to test your faith in him or sometimes send a great plague to punish people for their sins. People had so much belief in the Church no-one questioned the power of the Church and many people had believed this explanation of illness for over 1,000 years. Astrology -After so many people in Britain died during the Black Death (1348-49) people began to look for new ways to explain why they became sick. At this time doctors were called physicians. They would check someone’s urine and judge if you were ill based on its colour. They also believed they could work out why disease you had by looking at where the planets were when you were born.
