Salivary organ tumors are uncommon, including under 3 % of all neoplasia of head and neck district. Pleomorphic adenoma is the most well-known salivary organ tumor, representing 60-80% of amiable tumors of salivary organs. Generally they are found as singular one-sided, firm and portable, effortless, moderate developing mass. The board includes careful resection by shallow or absolute parotidectomy

Dental and Oral Care Under Clouds of COVID-19

Coronavirus (SARS-CoV-2) made the headlines after its initial breakout in Wuhan, China in December 2019 . Viral by genome, lethal by nature, strongly contagious by character, it succeeded in making a new chapter in everyone’s life in a very short span making it a pandemic. Despite the extensive efforts to limit its effects we stand at a point where more than 50 million people have lost their lives battling COVID. Its widespread growth has raised many concerns for global health, particularly health professionals and dentists precisely. As dentists are more prone to get affected in the course of their occupation, this review is an attempt to briefly summarize the virus and various protocols to be practiced by the dentists in their practices to protect their own health

Advanced Shift Register Design Using PSDRM Reversible Logic

Reversible logic is one of the most important issues at the moment, with the different areas like low power CMOS devices, quantum computing, nanotechnology, cryptography, optical computing, DNA Computing, digital signal processing (DSP) etc. This can be achieved using reversible logic. The main purpose for designing reversible logic is to minimize cost and throughput. Reversible logic considered as a computing model in which there is one-to-one scaling between their input and output. Power distribution is considered as one of the most important aspects while designing circuit. Reversible logic has become an encouraging technology in low power circuit design. That's because back logic uses only very less power, thus resulting in reduced power dissipation. In this report, we proposed a new reversible gate, and with the help of this gate we have designed our asserted D flip-flop by using the two reversible gates i.e. by using Fredkin and Feynman Gate. The proposed design is better in terms of the average power consumed, number of gates and garbage output than existing. In Shift Register, we introduce a reversible D flip-flop by using FRG and FG gate in the place of existing D flip-flop which used Sayem Gate. The asserted design consumes less energy compare to traditional circuitry. Here we use Pseudo expressions (PSDRM). By using this technology there is an improvement in the factors, such as number of transistors, garbage output, quantum cost and power

Antimicrobial prescribing patterns in surgical inpatient of tertiary care hospital in Eastern India

Background: Antimicrobials form the cornerstone of prescriptions for treating infection. Surgical management cannot be possible without the use of antibiotics. Severity of infection, suspected spectrum of organisms and their sensitivity, co-morbidities of the patient, route of antibiotic administration are the important parameter to consider before selecting antibiotic.Methods: Cross-sectional, hospital based, descriptive study was conducted in the ward of Surgery Department of IQ City Medical college, Durgapur over a period of 1 year. The relevant information was entered into the pretested preformats (containing name, age, sex, diagnosis, ongoing treatment as recorded from patients’ prescription slips or CRFs) and analyzed. Necessary permission was granted by the Institutional Ethical Committee and written informed consent was obtained from the patients prior to collecting their prescription slips/CRF.Results: Commonest cause of hospitalization was cholelithiasis (318 (32.7%)). Antimicrobials were the most commonly prescribed drugs (1626 (31.6%)). Single antibiotic prescribing frequency are similar to two antibiotic prescribing (both 44%). Piperacillin+Tazobactum combination most commonly prescribe antibiotic.Conclusions: Beta lactam antibiotic specifically Piperacillin (ATC class: J01D) were the most commonly prescribed antibiotic agents both before and after surgical procedures

Monitoring osseointegrated prosthesis loosening and fracture using electrical capacitance tomography.

A noncontact, noninvasive, electrical permittivity imaging technique is proposed for monitoring loosening of osseointegrated prostheses and bone fracture. The proposed method utilizes electrical capacitance tomography (ECT), which employs a set of noncontact electrodes, arranged in a circular fashion around the imaging area, for electrical excitations and measurements. An inverse reconstruction algorithm was developed and implemented to reconstruct the electrical permittivity distribution of the interrogated region from boundary capacitance measurements. In this study, osseointegrated prosthesis phantoms were prepared using plastic rods and Sawbone femur specimens, which were subjected to prosthesis loosening and fracture monitoring tests. The results demonstrated that the spatial location and extent of prosthesis loosening and bone fracture could be estimated from the ECT reconstructed permittivity maps. The resolution of the reconstructed images was further enhanced by a limited region tomography algorithm, and its accuracy in terms of identifying the severity, location, and shape of bone fracture was also investigated and compared with conventional full region tomography

On various notions of distance between subalgebras of operator algebras

Given any irreducible inclusion \mB \subset \mA of unital $C^*$-algebras with a finite-index conditional expectation E: \mA \to \mB, we show that the set of $E$-compatible intermediate $C^*$-subalgebras is finite, thereby generalizing a finiteness result of Ino and Watatani (from \cite{IW}). A finiteness result for a certain collection of intermediate $C^*$-subalgebras of a non-irreducible inclusion of simple unital $C^*$-algebras is also obtained, which provides a $C^*$-version of a finiteness result of Khoshkam and Mashood (from \cite{KM}). Apart from these finiteness results, comparisons between various notions of distance between subalgebras of operator algebras by Kadison-Kastler, Christensen and Mashood-Taylor are made. Further, these comparisons are used satisfactorily to provide some concrete calculations of distance between operator algebras associated to two distinct subgroups of a given discrete group

Noncontact Electrical Permittivity Mapping and pH-Sensitive Films for Osseointegrated Prosthesis and Infection Monitoring.

The objective of this paper is to develop a noncontact, noninvasive system for detecting and monitoring subcutaneous infection occurring at the tissue and osseointegrated prosthesis interface. It is known that the local pH of tissue can change due to infection. Therefore, the sensing system integrates two parts, namely, pH-sensitive thin films that can be coated onto prosthesis surfaces prior to them being implanted and an electrical capacitance tomography (ECT) algorithm that can reconstruct the spatial permittivity distribution of a region of space in a noncontact fashion. First, a thin film pH sensor was fabricated by spray coating, and tests confirmed that the film exhibited changes in its permittivity due to pH. Second, the ECT forward and inverse problems were implemented. Third, an aluminum rod was employed as a representative phantom of an osseointegrated prosthesis and then spray coated with the pH sensor. Finally, the film-coated phantom was immersed in different pH buffers, dried, and subjected to ECT interrogation and spatial permittivity reconstruction. The results validated that ECT was able to detect and localize permittivity variations correlated to pH changes
