Running head: ALEXANDER FLEMING 7 ALEXANDER FLEMING ALEXANDER FLEMING Student Name University Affiliation Alexander Fleming is synonymous with Penicillin, an antibiotic which has contributed immensely in the fight against bacteria. What few appreciate is the fact that the road to making the drug not only practical but acceptable was not an easy one and it took many years and a lot of effort for it to be produced in large quantities. Flemings experience teaches us that change can only occur through consistent and systematic efforts rather than instant fixes. This paper examines Alexander Fleming’s life, his work on penicillin and how this work has contributed a positive change to the world. Childhood and early career Born in 1881 on the 6th of August in Scotland few would predict that the third born of a farmer by the name Hugh Fleming would grow to become one of the most renowned scientists in the medicine world. He attended the Loudoun Moor School where he earned a scholarship at Kilmarnock Academy and later moved to London to study at an institute named Royal Polytechnic. He was attached in a shipping Company for four years working as a shipping officer. However his uncle John Fleming was determined that Alexander should follow in his footsteps to be a physician and thus after inheriting some money from him, Alexander enrolled at a medical school in Paddington where he successfully completed his course in 1906 with a distinction in a MBBS degree. Later in 1908 he added to his increasing accolades, a BSc degree in Bacteriology and later went back to his previous medical institute to become a lecturer. In addition to his careers in the medical world, Fleming as evoked by Fleming (2007) is also known to have participated in the First World War where he took up the position of a captain in the Royal Army Medical Corps and thereafter he went back to the St Mary’s hospital where he had previously worked in 1918. In 1928 he added to his long career another accolade by becoming a professor in Bacteriology at the University of London where he wrote may articles on Bacteriology, immunology and Chemotherapy. Discovery of penicillin It was penicillin that really put Alexander Fleming on the map though the discovery was accidental. Initially, Fleming was investigating properties of staphylococci. However, his laboratory was often untidy due to a lot of research work. He once stacked all his cultures of staphylococci in a bench in his laboratory and upon his return he found that the culture had been contaminated with a fungus, and after spotting the mould, Fleming spotted a ‘mould juice’ that he later renamed penicillin (Hugh, 2002). He carried out some investigations which proved that penicillin has some positive effects of anti-bacteria affected various bacteria such as staphylococci and other pathogens that cause diphtheria, meningitis and pneumonia but the drug nevertheless did not address the problem of Gram negative bacteria that cau ...

Thoracotomy is the surgical procedure with an incision made to access the pleural space and the contents of the thoracic cavity. Given the structures to be accessed with in the cavity, different incisions have been established to easy the procedure and these incisions qualify the types of thoracotomies to be studied hereunder. PRE OP OPTIMIZATION FOR SPECIFIC FACTORS The outcome of surgical procedures is not measured only by clinical end points but also shorter stays and lower costs. Patients’ discharge is delayed commonly due to inadequate pain relief, infection, arrhythmias, prolonged air leak and debility. Many complications that occur from thoracic operations can be anticipated. An aggressive preoperative work up mitigates morbidity and shortens convalescence. APPROACH CONSIDERATIONS There are about three principles that can guides the choice of the thoracotomy incision to be used I. Adequate exposure must be achieved. The choice of incision is aided by a thorough understanding of the surface anatomy and a comprehensive review of the radiographic images that are obtained preoperatively. II. Chest-wall function and appearance should be preserved to the extent possible. This principle include non-spreading video-assisted thoracoscopic surgery (VATS) procedures, muscle-sparing techniques, avoidance of excessive rib retraction, and rib preservation when possible. III. The third principle is that closure must be meticulous and appropriate. Strict layered closure is the rule for thoracic surgical incisions. Every effort should be made to approximate the individual divided chest-wall muscles in appropriate layers; otherwise, a significant delay in the recovery of range of motion (ROM) may result. Care must be taken to avoid over approximating the ribs and to prevent an override; this will help minimize postoperative pain. POST-OPERATIVE CARE AND MONITORING

A transition period regarding in vitro medical device (IVD) regulation in the European Union (EU) is upon us. The former IVDD regulations are phasing out and IVDR 2017/746 has already taken its place as the acting regulation for IVD manufacturers but also lab developed tests (LDTs) and health institutions. In our upcoming webcast we will talk about the roles and significance of IVDR and ISO 13485 certification for clinical labs and for Golden Helix as a medical device manufacturer. Join us as we will introduce VarSeq 2.6.1 complete with Dx Mode, which offers the use of VarSeq as CE marked medical device. Even more we will also present strategies to facilitate the transition of Golden Helix customers to operate in accordance with IVDR.
