Predictability of surgical techniques used for coverage of multiple adjacent gingival recessions--A systematic review

Predictable coverage of multiple adjacent gingival recessions (MAGRs) is a major challenge for clinicians. Although several surgical techniques have been proposed to treat MAGR, it is still unclear as to what extent the proposed approaches may lead to predictable root coverage. The aim of this article is to identify the predictability of the available surgical techniques used to achieve complete root coverage (CRC) of Miller Class I, II, and III MAGRs.

Bovine pericardium based non-cross linked collagen matrix for successful root coverage, a clinical study in human

Introduction The aim of this study was to clinically assess the capacity of a novel bovine pericardium based, non-cross linked collagen matrix in root coverage. Methods 62 gingival recessions of Miller class I or II were treated. The matrix was adapted underneath a coronal repositioned split thickness flap. Clinical values were assessed at baseline and after six months. Results The mean recession in each patient was 2.2 mm at baseline. 6 Months after surgery 86.7% of the exposed root surfaces were covered. On average 0,3 mm of recession remained. The clinical attachment level changed from 3.5 ± 1.3 mm to 1,8 ( ± 0,7) mm during the observational time period. No statistically significant difference was found in the difference of probing depth. An increase in the width of gingiva was significant. With a baseline value of 1.5 ± 0.9 mm an improvement of 2.4 ± 0.8 mm after six month could be observed. 40 out of 62 recessions were considered a thin biotype at baseline. After 6 months all 62 sites were assessed thick. Conclusions The results demonstrate the capacity of the bovine pericardium based non-cross linked collagen matrix for successful root coverage. This material was able to enhance gingival thickness and the width of keratinized gingiva. The percentage of root coverage achieved thereby is comparable to existing techniques. This method might contribute to an increase of patient's comfort and an enhanced aesthetical outcome.

The acetabular wall index for assessing anteroposterior femoral head coverage in symptomatic patients

Understanding acetabular pathomorphology is necessary to correctly treat patients with hip complaints. Existing radiographic parameters classify acetabular coverage as deficient, normal, or excessive but fail to quantify contributions of anterior and posterior wall coverage. A simple, reproducible, and valid measurement of anterior and posterior wall coverage in patients with hip pain would be a clinically useful tool.

What is the evidence supporting the prevention of osteoarthritis and improved femoral coverage after shelf procedure for Legg-Calvé-Perthes disease?

The evidence supporting continued use of shelf acetabuloplasty in Legg-Calvé-Perthes disease (LCPD) is not well-defined, and there is controversy regarding the long-term benefits related to clinical and functional improvement.

Triple innominate osteotomy for Legg-Calvé-Perthes disease in children: does the lateral coverage change with time?

Triple innominate osteotomy (TIO) is one of the modalities of surgical containment in Legg-Calvé-Perthes disease (LCPD). However, overcoverage with TIO can lead to pincer impingement.

The Evolution of Media Coverage of Historical Sports Controversies

This thesis will cover sports controversies throughout the 20th Century in the context of the media’s newspaper coverage of the events. The 1919 Black Sox Scandal, the debate over American participation in the 1936 Olympics, and Muhammad Ali’s conversion to the Nation of Islam, standing as a notorious public figure, and conscientious objection to the Vietnam War will represent the three sports controversies. The media’s adherence to cultural norms is clear in all three cases. The consistent devotion to the cultural and racial atmosphere of their respective eras was constant and helped to perpetuate accepted, mainstream cultural attitudes. Cultural and racial norms were followed in the coverage of the three discussed controversies. The anti-Semitism and racially intolerant sentiments in America during great waves of immigration in the early 1900s allowed for journalists to freely vilify Jews as corrupters of baseball and the ballplayers who were rumored to have thrown the 1919 World Series. The white ballplayers were supported in the press, who protected their own and blamed outsiders. Jim Crow and the Americanization movement forced African American and Jewish newspapers to limit their journalistic bias on both sides of the debate over American participation in the 1936 Berlin Olympics. The white, mainstream press was void of bias as the spirit of isolationism in America triumphed over journalist’s leanings in the Olympic debate. The racial tension created by the Civil Rights movement of the 1960s created an atmosphere that allowed mainstream journalists to heap endless criticism on Muhammad Ali as he gained fame. By portraying him as a villain of society as both a religious radical and traitor to America, journalists created a common enemy in the minds of white America. In all three cases, a pattern of journalists expressing the state of cultural and racial norms of the era is present and significant.

Health insurance coverage of Hispanic adults: An assessment of subgroup difference and the impact of immigration

This research explores the health insurance coverage of various Hispanic subgroups in comparison to non-Hispanic whites and blacks. The impact of immigration status is also considered as we hypothesize that nativity, duration, and naturalization tap a possible process of structural acculturation that increases access to insurance coverage for Hispanic groups. We find that the immigration variables impact the type of insurance reported. However, race/ethnic disparities continue to exist, with the various Hispanic subgroups more likely to report miscellaneous government health insurance or no health insurance coverage as compared to non-Hispanic whites.

Capture, crawl, cross: the T cell code to breach the blood-brain barriers

The central nervous system (CNS) is an immunologically privileged site to which access of circulating immune cells is tightly controlled by the endothelial blood-brain barrier (BBB; see Glossary) localized in CNS microvessels, and the epithelial blood-cerebrospinal fluid barrier (BCSFB) within the choroid plexus. As a result of the specialized structure of the CNS barriers, immune cell entry into the CNS parenchyma involves two differently regulated steps: migration of immune cells across the BBB or BCSFB into the cerebrospinal fluid (CSF)-drained spaces of the CNS, followed by progression across the glia limitans into the CNS parenchyma. With a focus on multiple sclerosis (MS) and its animal models, this review summarizes the distinct molecular mechanisms required for immune cell migration across the different CNS barriers.
