Researchers show effectiveness of non-surgical treatment of lumbar spinal stenosis

(Press-News.org) (Boston)--Patients with spinal stenosis (SS) experienced good short term benefit, lasting from weeks to months, after receiving epidural steroid injections (ESI).
These findings, which appear in a letter in the journal Pain Medicine, contradict a previously published New England Journal Medicine (NEJM) study that found epidural steroid injections were not helpful in spinal stenosis cases.
It has been one year since the publication of "A Randomized Trial of Epidural Glucocorticoid Steroid Injections for Spinal Stenosis." This was a large scale clinical trial evaluating the use of ESI for SS. Pain physicians argued the validity of the results based on the experimental set-up and study design. In academic meetings and clinical discussion among pain specialists, some very much agreed with the main study result: ESI are not very helpful for SS, while others reported consistent, short-term pain benefit of SS symptoms.
Lumbar spinal stenosis is a common painful problem due to worsening constrictive arthritis in the low back, affecting the legs and walking.
Researchers from Boston University School of Medicine (BUSM) performed a retrospective case series, using multiple methods of injections and various steroid choices and found specific epidural steroid injections to be very affective.
"The 2014 NEJM study on lumbar epidural steroids for spinal stenosis pain allowed for extreme variability in injection method and steroid type," explained co-author Anthony K. Savino, MD, chief resident, BUSM's department of neurology. "We feel that interlaminar (between vertebrae) injection, at the worst stenosis level, with long acting steroid is very helpful for spinal stenosis pain, and our case series supports this. Doing injections the way we propose will help with spinal stenosis pain, making walking easier/better and may help some patients avoid surgery."
As there are few non-surgical options for lumbar spinal stenosis the authors suggest future large scale trials be designed using interlaminal injection at the worst SS level with long acting steroids, variable physician preference, as prior studies.

An international team of scientists have dated a species of fossil monkey found across the Caribbean to just over 1 million years old.
The discovery was made after the researchers recovered a fossil tibia (shin bone) belonging to the species of extinct monkey Antillothrix bernensis from an underwater cave in Altagracia Province, Dominican Republic. The fossil was embedded in a limestone rock that was dated using the Uranium-series technique.
In a paper published this week in the well renowned international journal, the Journal of Human Evolution, the team use three-dimensional ...

Tropical Storm Kevin's center was several hundred miles south-southwest of Baja California when NASA's Aqua satellite passed overhead and saw some associated high clouds streaming over the peninsula.
The MODIS and the AIRS instruments aboard Aqua captured visible and infrared images of Kevin on September 3 at 20:50 UTC (4:50 p.m. EDT). The visible image from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument provided look at Kevin's clouds. MODIS showed a somewhat elongated tropical storm with a fragmented band of thunderstorms wrapping into the low-level ...

Scientists studying how a heat-loving microbe transfers its DNA from one generation to the next say it could further our understanding of an extraordinary superbug.
Sulfolobus is part of the Archaea kingdom - a single-cell organism similar to bacteria - which was isolated in hot springs on the island of Hokkaido, Japan.
Some Archaea live ordinary lives in mundane environments such as lakes, seas and insect and mammal intestinal tracts, while others live extraordinary lives pushed to extremes in incredibly harsh habitats such as deep sea hydrothermal vents, volcanic ...

"Objects of granular media, such as a sandcastle, consist of millions or billions of grains. The computation time needed to produce photorealistic images amounts to hundreds to thousands of processor hours," Professor Carsten Dachsbacher of the Institute for Visualization and Data Analysis of KIT explains. Materials, such as sand, salt or sugar, consist of randomly oriented grains that are visible at a closer look only. Image synthesis, the so-called rendering, is very difficult, as the paths of millions of light rays through the grains have to be simulated. "In addition, ...

Nowadays, internet auctions play an important role in online trading. No matter whether you want to buy a hedge trimmer or an antique pocket watch - unlike purchases by a click at a fixed price, online auctions provide the atmosphere of a competition for the auction object. Whoever perceives the competition of real contenders, e.g. by avatars or photos on the screen, wishes to stay in the race - and increases his bid. This is a result of a KIT study with more than 450 test persons.
Online auctions combine shopping with entertainment, fun, and excitement. This is the ...

Action to prevent tooth decay in children, such as supervised tooth brushing and fluoride varnish schemes, are not just beneficial to children's oral health but could also result in cost savings to the NHS of hundreds of pounds per child, so says a leading dental health researcher.
Professor Elizabeth Kay, Foundation Dean of the Peninsula Dental School from Plymouth University Peninsula Schools of Medicine and Dentistry, has carried out the first economic evaluation of public health measures to reduce tooth decay in children at high risk, in association with the National ...

When a jogger sets out on his evening run, the active movements of his arms and legs are accompanied by involuntary changes in the position of the head relative to the rest of the body. Yet the jogger does not experience feelings of dizziness like those induced in the passive riders of a rollercoaster, who have no control over the abrupt dips and swoops to which they are exposed. The reason for the difference lies in the vestibular organ (VO) located in the inner ear, which controls balance and posture. The VO senses ongoing self-motion and ensures that, while running, ...

Patients with cancer of the esophagus--also known as the gullet--are often given chemo- or radiotherapy, with the aim of shrinking the tumor before it is surgically removed. Increasingly positron emission tomography (PET) is being used to monitor the size of the tumor during the treatment. To date, however, no benefit for patients has ensued, as Milly Schröer-Günther and co-authors show in an original article in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2015; 112: 545-52).
PET is an imaging technique that makes a tumor in ...

Despite continued medical advances, infectious diseases kill over 10 million people worldwide each year. The ecological complexity of many emerging disease threats--interactions among multiple hosts, multiple vectors and even multiple parasites--often complicates efforts aimed at controlling disease. Now, a new paper co-authored by a University of Colorado Boulder professor is advancing a multidisciplinary framework that could provide a better mechanistic understanding of emerging outbreaks.
In a study published today in the journal Science, researchers demonstrate how ...

In the game of wheat genetics, Jorge Dubcovsky's laboratory at UC Davis has hit a grand slam, unveiling for the fourth time in a dozen years a gene that governs wheat vernalization, the biological process requiring cold temperatures to trigger flower formation.
Identification of the newly characterized VRN-D4 gene and its three counterpart genes is crucial for understanding the vernalization process and developing improved varieties of wheat, which provides about one-fifth of the calories and proteins that we humans consume globally.
The new study, reported online in ...
