Treating gum disease reduces prostate symptoms, CWRU researchers find

2015-05-05
(Press-News.org) Treating gum disease reduced symptoms of prostate inflammation, called prostatitis, report researchers from Case Western Reserve University School of Dental Medicine and the Departments of Urology and Pathology at University Hospitals Case Medical Center.

Previous studies have found a link between gum disease and prostatitis, a disease that inflames the gland that produces semen. Inflammation can make urination difficult.

"This study shows that if we treat the gum disease, it can improve the symptoms of prostatitis and the quality of life for those who have the disease," said Nabil Bissada, chair of Case Western Reserve's Department of Periodontics and the new study's corresponding author.

The researchers reported their findings in the Dentistry article, "Periodontal Treatment Improves Prostate Symptoms and Lowers Serum PSA in Men with High PSA and Chronic Periodontitis." Naif Alwithanani, a graduate student in the dental school, led the investigation as part of his residency in periodontics.

Bissada explained that gum disease not only affects the mouth, but is a system-wide condition that can cause inflammation in various parts of the body. The dental school has previously found a link between gum disease and fetal deaths, rheumatoid arthritis and heart disease.

The new prostate study

Researchers studied 27 men, 21 years old and older. Each had had a needle biopsy within the past year that confirmed inflammation of the prostate gland, and a blood test that showed elevated prostate specific antigen (PSA) levels--possible signs of inflammation and cancer.

The men were assessed for symptoms of prostate disease by answering questions on the International-Prostate Symptom Score (IPSS) test about their quality of life and possible urination issues.

Researchers found 21 of the 27 participants had no or mild inflammation, but 15 had biopsy-confirmed malignancies. Two had both inflammation and a malignancy.

The men also had to have at least 18 teeth and were examined for signs of gum disease, such as increased levels of inflammation and bleeding and/or loose teeth due to attachment and bone loss.

All the men had moderate to severe gum disease, for which they received treatment. They were tested again for periodontal disease four to eight weeks later and showed significant improvement.

During the periodontal care, the men received no treatment for their prostate conditions. But even without prostate treatment, 21 of the 27 men showed decreased levels of PSA. Those with the highest levels of inflammation benefited the most from the periodontal treatment. Six participants showed no changes. Symptom scores on the IPSS test also showed improvement.

Bissada is now conducting follow-up research to support the first study's findings. He hopes to make periodontal treatment a standard part of treating prostate disease, much like cardiac patients are often encouraged to visit their dentist before undergoing heart procedures and a dental checkup is advised for women who are pregnant or considering pregnancy.

The dark side of cannabis

2015-05-05
Although the use of cannabis as a medical drug is currently booming (Dtsch Arztebl Int 2012; 109: 495-501), we should not forget that leisure time consumption--for example, smoking weed--can cause acute and chronic harms. These include panic attacks, impaired coordination of movement, and nausea, as Eva Hoch and colleagues show in a topical review article in Deutsches Ärzteblatt International (Dtsch Arztebl Int 2015; 112: 271-8). The symptoms depend on a patient's age, the amount of the drug consumed, and the frequency of drug use. It also matters in which form the ...

First field-effect transistors on hybrid perovskites fabricated for first time

2015-05-05
(Winston-Salem, N.C. - May 5, 2015) - Researchers from Wake Forest University and the University of Utah are the first to successfully fabricate halide organic-inorganic hybrid perovskite field-effect transistors and measure their electrical characteristics at room temperature. "We designed the structure of these field-effect transistors that allowed us to achieve electrostatic gating of these materials and determine directly their electrical properties," said lead author, Oana Jurchescu, an assistant professor of physics at Wake Forest. "Then we fabricated these transistors ...

This news release is available in German. Overturning cars, flying missiles, and airplanes speeding across the screen -- on modern computers, 3D objects can be calculated in a flash. However, many surfaces still look unnatural. Whether it is skin, stone or wax -- on the computer screen, all materials look alike, as if the objects had all been cut out of the same kind of opaque material. This is about to change: TU Wien (Vienna), the University of Zaragoza and the video game company Activision-Blizzard have developed a new mathematical method which makes surfaces appear ...

How our view of what makes us happy has changed in 80 years

2015-05-05
Our view of what makes us happy has changed markedly since 1938. That is the conclusion of the psychologist Sandie McHugh from the Univeristy of Bolton who has recreated a famous study of happiness conducted in Bolton in 1938. She will present her study today, Tuesday 5 May 2015, to the Annual Conference of the British Psychological Society in Liverpool. In 1938 Mass Observation placed an advertisement in the the Bolton Evening News asking readers to answer the question 'What is happiness?'. A total of 226 people sent letters in reply, and they were asked to help compile ...

'Freezing a bullet' to find clues to ribosome assembly process

Freezing a bullet to find clues to ribosome assembly process
2015-05-05
Ribosomes are vital to the function of all living cells. Using the genetic information from RNA, these large molecular complexes build proteins by linking amino acids together in a specific order. Scientists have known for more than half a century that these cellular machines are themselves made up of about 80 different proteins, called ribosomal proteins, along with several RNA molecules and that these components are added in a particular sequence to construct new ribosomes, but no one has known the mechanism that controls that process. Now researchers from Caltech and ...

New centimeter-accurate GPS system could transform virtual reality and mobile devices

2015-05-05
AUSTIN, Texas -- Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a centimeter-accurate GPS-based positioning system that could revolutionize geolocation on virtual reality headsets, cellphones and other technologies, making global positioning and orientation far more precise than what is currently available on a mobile device. The researchers' new system could allow unmanned aerial vehicles to deliver packages to a specific spot on a consumer's back porch, enable collision avoidance technologies on cars and allow virtual ...

Changing attitudes about sex

2015-05-05
SAN DIEGO, Calif. (May 5, 2015)-- Acceptance of premarital sex is at an all-time high along with an acceptance of homosexuality, find researchers led by Jean M. Twenge from San Diego State University. The researchers -- also including Ryne Sherman from Florida Atlantic University and Brooke E. Wells from Hunter College -- analyzed data from the General Social Survey, a nationally representative survey of more than 33,000 U.S. adults taken between 1972 and 2012. They found substantial generational shifts in attitudes toward non-marital sex and number of sexual partners. ...

Proteomics provides new leads into nerve regeneration

2015-05-05
Using proteomics techniques to study injured optic nerves, researchers at Boston Children's Hospital have identified previously unrecognized proteins and pathways involved in nerve regeneration. Adding back one of these proteins--the oncogene c-myc--they achieved unprecedented optic nerve regeneration in mice when combined with two other known strategies. The findings were published online April 30 by the journal Neuron. Researchers have been trying for many decades to get injured nerves in the brain and spinal cord to regenerate. Various molecules have been targeted ...

Shedding light on rods

2015-05-05
"Imagine a tiny spotlight like those used in theatres but with a light ray measuring only a few nanometres, which shines light on a given spot but leaves everything else in the dark," explains Monica Mazzolini, SISSA research scientist, "That's how the optic fibres we used in our experiment work". Mazzolini, first author of a paper just published in PNAS, literally shut herself in a "darkroom" lit with infrared light only to stimulate rods, the light-sensitive cells of the retina (for night vision), with these extremely focused light beams in vitro. In their study, Mazzolini ...
