Classification of Anti‐Bacterial Agents and Their Functions

Bacteria that cause bacterial infections and disease are called pathogenic bacteria. They cause diseases and infections when they get into the body and begin to reproduce and crowd out healthy bacteria or to grow into tissues that are normally sterile. To cure infec‐ tious diseases, researchers discovered antibacterial agents, which are considered to be the most promising chemotherapeutic agents. Keeping in mind the resistance phenomenon developing against antibacterial agents, new drugs are frequently entering into the mar‐ ket along with the existing drugs. In this chapter, we discussed a revised classifcation and function of the antibacterial agent based on a literature survey. The antibacterial agents can be classifed into fve major groups, i.e. type of action, source, spectrum of activity, chemical structure, and function.
Perineal Trauma[taliem.ir]

Perineal Trauma at Childbirth

Review of historical literature confrms that perineal injury has occurred during childbirth throughout the ages and that various methods and material were used by accoucheurs in an attempt to restore the integrity of severely traumatised tissue. Perineal stitching following childbirth was advocated in ancient writings on midwifery and obstetrics, however the procedure was not routinely practiced. Women remained the prominent fgure during confnements in the early centuries and male physicians or barber-surgeons were only called in as a last resort if problems occurred. During the eighteenth century the introduction of forceps together with episiotomy to facilitate diffcult deliveries had a major impact on the extent of perineal trauma and its subsequent repair. Furthermore, women were encouraged to deliver in a more supine position rather than upright so the perineum was more accessible and the full extent of perineal trauma sustained could be assessed. During this period more attention was made to minimising perineal trauma and various methods including supporting the perineum and applying pressure to the vertex to prevent rapid expulsion were implemented. By the end of the nineteenth century practitioners were advised to suture all perineal trauma. However, it was not until the early twentieth century that local anaesthetic was advocated to ease the pain prior to performing and suturing episiotomies. In the UK, midwives did not receive any formal training until the late eighteenth century and it was not until the late twentieth century that midwives were permitted to undertake perineal suturing.

Orofacial Pain: Classifcation and Road Map to Clinical Phenotypes

The orofacial region consists of heterogeneous tissues that make diagnosing and treating pain conditions a challenging task. Vital to these processes are well-structured classifcation systems that cover the breadth of chronic orofacial pain conditions and provide diagnostic criteria to enhance our ability to properly identify and categorize clinical events in an agreed pattern. A revision of the classifcation systems for orofacial pain disorders developed respectively by the International Association for the Study of Pain, the International Headache Society, the American Academy of Orofacial Pain, and the American Academy of Craniofacial Pain reveals a number of defciencies and inconsistencies ranging from terminology to the structure itself and the set of diagnostic criteria. To improve communication and enable effective collaborative work, we are at the crossroads for the development of a new multiaxial classifcation system using ontological principles to build a realistic and comprehensive representation of orofacial pain disorders. With research focusing on pain biomarkers, optimizing the systematization of data collection may contribute to identifying clinical phenotypes of chronic orofacial pain conditions that have the most impact on patient life.
