A measure of clinical outcomes in dental implant surgery flapless surgery versus flap technique in posterior maxilla of post menopause women

Abstract: The aim of this study is to examine the clinical outcomes of implants inserted using split mouth study and to measure patients’ satisfaction using visual analogue scale in flapless and conventional flap techniques in post menopause women age 50 years or over. Materials and methods: This study is a retrospective split mouth study of flapless vs flap technique involving the study of dental records of 16 post-menopause of patients undergoing bilateral implant surgery in the posterior maxilla. A total of 45 implants with no augmentative procedures were selected from 16 patients for the study. The patients were divided into two groups: the control group had 21 implants placed by full flap technique, and the test group consisted of 24 implants inserted using flapless procedure. Only those patients with comprehensive clinical record were included in this study. The treatment outcomes were measured using key words: implant survival, Visual Analogue Scale (VAS), Periotest, x-ray assessment. Results and Discussion: The results showed that flapless surgery had comparable, similar results as compare to flap surgery: survival rate (95.8% and 95.2%), Using visual analogue scale (VAS=0 to 10), flapless surgery revealed to have less: pain, swelling, bleeding and speech impairment and had better overall satisfaction at one day and one week than flap technique than the flap counterpart (*P<0.05). No significant difference in bone resorption at 3 months. After one year, bone change in the flap group vs the flapless group was statistically significant [-0.53 (±0.57) vs +0.08 (±0.49), **P<0.005]. No significant difference in Periotest value (PTV). Conclusion: This study showed that implant flapless surgery is a minimal invasive, effective, and novel technique that can render a significantly better early stage satisfaction outcome as compare to the traditional flap method. Flapless implantation resulted in minimal bone loss, less pain, less complications, and comparable good PTV.

A morphometric anatomical study of the right coronary artery in Vietnamese

Abstract: Coronary artery disease (CAD) is a major cause of death and disability in developed countries, and incidence of CAD is increasing annually in the un-derdeveloped world. Today, percutaneous coro-nary intervention plays a major role both in diagno-sis and treatment of CAD. As a result, an under-standing of the anatomy of the coronary artery sys-tem is vital cardiologists. Yet, studies are lacking that focus on Vietnamese hearts. The objective of this study was to examine the morphometric ana-tomical variation of the right coronary artery (RCA) in Vietnamese cadavers. The hearts from 125 ca-davers were used in the study. In all hearts, the RCA originated from the right aortic sinus, had a right marginal branch, and gave rise to one to three right posterior ventricular (RPV) branches. In 96.8% of hearts, the posterior interventricular branch (PIV) originated from the RCA; in 3.2% from the left circumflex artery (LCX), and the mean diameter was 2.09 mm ± 0.62 mm. The RCA had a mean diameter and length of 4.21 mm ± 0.64 mm and 122.5 mm ± 17.8 mm, respectively, and terminated between the crux and left border (72%) and at the crux (14.4%). The origin of the sinoatri-al node artery was 81.6% from the RCA, 16.8% from the LCX, and 1.6% from both the RCA andLCX. There were one to four right atrial branches observed across the hearts studied; a maximum of 32% (one branch) and a minimum of 12.8% (four branches). In 68.8% of hearts the conus artery originated from the RCA. In 8.8%, it arose from the right aortic sinus at the same site as the RCA, but in 22.4% away from this site of origin. The RCA gave rise to one to eight right anterior ventric-ular (RAV) branches (i.e., because they are at the anterior surface of the right ventricular); with the highest incidence of 3 branches in 37.6% of hearts. The RCA gave rise to one to seven left posterior ventricular branches; the majority of cas-es, 28.8% gave rise to 4 branches. The rare inci-dence of myocardial bridging in the right coronary system occurred in 7.2% of hearts, and each case involved the posterior interventricular branch. An-atomical variations of the RCA system can cause difficulties in imaging interpretation and interven-tional procedures. This study is the first to docu-ment these variations of the RCA system in Viet-namese hearts, contributing knowledge that is es-sential for physicians.

Pathophysiology Updates for Chronic Obstructive Pulmonary Disease

Abstract: New insights into cellular and molecular mechanisms have recently emerged, leading respiratory physicians to re-examine and even revise current phenotype classifications of COPD. Studying mechanisms of COPD must now go beyond mere enumeration of separate pathophysiological features, for example airflow limitation, air trapping, and inhomogeneity of ventilation distribution. Rather, how to precisely define various phenotypes of COPD patients should become the main objective for all respiratory physicians, because accurate phenotypes will lead to better cures and, hence, better prognosis for COPD patients. During the last decade respiratory physicians have gained much insight into COPD pathophysiology. Yet we are still far from mastering effective biological tools, including genetic and molecular fingerprints readily available for all patients for easy diagnosis and effective prevention of worsening of COPD.

The Classical Theory of Light Colors: a Paradigm for Description of Particle Interactions

Abstract: The color is an interaction property: of the interaction of light with matter. Classically speaking it is therefore akin to the forces. But while forces engendered the mechanical view of the world, the colors generated the optical view. One of the modern concepts of interaction between the fundamental particles of matter – the quantum chromodynamics – aims to fill the gap between mechanics and optics, in a specific description of strong interactions. We show here that this modern description of the particle interactions has ties with both the classical and quantum theories of light, regardless of the connection between forces and colors. In a word, the light is a universal model in the description of matter. The description involves classical Yang-Mills fields related to color.

Computer aided concept for enhancing motivation and thinking while teaching and learning medical physiology.

Abstract: We wanted to refine the old computer aided concept we developed several years ago for teaching and learning medical physiology, by adding new tools to enhance motivation and thinking of both medical students and teachers. Since all the future exams of our University will rely mainly on a written, or even better, computerized multiple choice format, we focused on tools that motivate teachers in writing good multiple-choice questions (MCQ), not only for final exam but for teaching students as well, and tools to motivate students to perform MCQ tests during semester. We developed a concept of a Multifunctional or Enhanced MCQ which offer teachers, when using our software, the possibility to write questions with one statement and up to 10 answers which in their turn can be individually enabled or disabled by them. We conceived a precise protocol for calculation of Current P index and Current D index of each MCQ which is useful for a permanent, during semester, refining of poor quality questions or to adjust current overall difficulty of the MCQ set according to student performances and/or teacher expectancies.
