Say Cheese!

There are a couple of reasons you might want to take a screenshot (a.k.a., screen capture or screen grab) of your desktop or an application window. One of the most common is to send the image to tech support to show a problem you're experiencing. Whatever your motive, here's how to take a screenshot on both Windows and Mac.

Cloudy Days

On June 19 there was a four-hour security glitch at Dropbox. During that four-hour period anyone could log into any account with any password. If someone knew the email you used to login they could supply any password at all and it would work. Essentially it didn’t matter how powerful the encryption scheme Dropbox was using to secure your files was as the security flaw temporarily allowed anyone to login to your account and be authenticated as though they were you—a procedure that would bypass the strongest encryption in the world since the system believed the interloper was a valid user on the account. Here's a fix.

Attack of the Killer Ads

Ad-blocking extensions like Adblock Plus are wildly popular among web power users, whether used to kill distracting ads or to make the most of a slow connection. Their weakness: These extensions only work with the browser you've installed them on. If you're interested in blocking advertising from specific domains globally, you can edit your computer's (or, better yet, your router's) hosts file to stop your browser, your phone's browser, or any other application from visiting that advertising server completely.

À propos d’une ulcération palatine

un patient de 38 ans d’origine polonaise est admis pour
une ulcération palatine peu douloureuse évoluant
depuis environ 3 jours. Elle se situe de part et d’autre de la
ligne médiane et elle expose en profondeur l’os maxillaire (fig. 1).
Ce patient tabagique ne présente par ailleurs aucun autre antécédent
particulier. L’interrogatoire systématique ne met en évidence
ni prise de cocaïne, ni injection locale de vasoconstricteur
ou d’autre produit caustique pouvant expliquer la présence de
cette ulcération. Le reste de la cavité buccale est exempt de toute
autre lésion.
Une biologie courante révèle l’existence d’un syndrome inflammatoire
(CRP à 14,2 mg/L). Un scanner du massif facial ne révèle
ni atteinte osseuse ni communication naso-buccale. Il nous
oriente vers un diagnostic de lésion granulomateuse inflammatoire
ou infectieuse.
Un frottis de la lésion et un prélèvement biopsique sont réalisés.
Dans l’attente des résultats, le patient est placé sous antibiothérapie
préventive (Augmentin 4x1gr I.V.) et soins locaux à base
d’éosine acqueuse 2%.
Face à ce type de lésion les diagnostics différentiels suivants doivent
être évoqués :
1. Ulcération traumatique, iatrogène (automutilation, blessure
par objet, injection de vasoconstricteur, médicaments…).
2. Néoplasies :
a. adénocarcinomes salivaires : carcinome adénoïde kystique,
carcinome muco-épidermoïde, adénocarcinome à cellules acineuses,
adénocarcinome polymorphe bien différencié, tumeur
mixte maligne ;
b. Lymphomes ;
c. Sarcomes ;
d. Lésion métastatique.
3. Troubles inflammatoires chroniques :
a. Périadénite de Sutton ;
b. Sialométaplasie nécrosante ;
c. Lichen plan érosif ;
d. Lupus érythémateux discoïde ;
e. Réaction lichénoïde ou lupique.
4. Infections chroniques :
a. Tuberculose ;
b. Syphilis primaire ou tertiaire ;
c. Mycose profonde.
5. Vasculite : granulomatose de Wegener.
Les sérologies pratiquées à la recherche de syphilis et d’herpès
se sont avérées négatives. Sous traitement, la lésion a involué,
le fond de l’ulcération s’est comblé en 10 jours, aux deux tiers,
par du tissu de granulation (fig. 2).
Quel est votre diagnostic ?

Quels examens comple´mentaires re´alisez-vous ? Quelle prise en charge proposez-vous ?

Reponses
Une tomodensitomerie permet de situer avec plus de pre´cision
la le´sion osseuse dans les trois dimensions de l’espace et
ses rapports avec les e´le´ments anatomiques voisins (fig. 2, 3).
Diagnostics diffe´rentiels
Ils regroupent l’ensemble des le´sions radio-claires bien
de´limite´es [1]. La conservation de la vitalite´ pulpaire des
dents adjacentes et, ici, la localisation a` distance des e´le´-
ments dentaires permettent d’e´liminer les kystes odontoge`
nes et la lacune de Stafne [2]. Le kyste essentiel, le
kyste e´pidermoı ¨de, le granulome re´parateur central et l’ame´-
loblastome font partie, au contraire, des diagnostics envisageables
[3].
Prise en charge the´rapeutique
Une intervention sous anesthe´sie ge´ne´rale est programme´e
e´tant donne´ le jeune aˆge de l’enfant. L’aspect be´nin initial de
la le´sion n’a pas justifie´ une biopsie pre´alable. Un abord
endobuccal, avec incision line´aire muqueuse jusqu’au contact
osseux re´alise´e en regard du germe de la dent 35 sur une
distance de 4 cm sous la ligne de jonction mucogingivale
vestibulaire, permet l’insertion d’une lame malle´able exposant
la corticale externe et la tre´panation osseuse conduisant
a` une cavite´ osseuse vide (fig. 4). Il n’est pas retrouve´ de
paroi kystique. Ne´anmoins, un curetage minutieux permet le
recueil de petits fragments osseux confie´s au laboratoire
d’anatomopathologie.
Le diagnostic est ici quasiment re´alise´ en perope´ratoire. La
cavite´ est entie`rement vide. Seul l’examen anatomopathologique
permet de poser le diagnostic de certitude : kyste
essentiel ou traumatique ou he´morragique. Une tre`s fine
membrane conjonctive riche en fibroblaste et tatoue´e de
grains d’he´moside´rine est observe´e a` l’examen microscopique.
Le contenu cavitaire est inexistant. Les suites ope´ratoires
sont simples. Cette tre´panation corticale est suffisante
pour stimuler la re´ge´ne´ration osseuse par le biais probable
d’une re´organisation du caillot sanguin forme´ [4]. Une surveillance
radiographique est propose´e, la gue´rison est favorable
en re`gle ge´ne´rale sans re´cidive.

Looking Ahead

As computational power rises exponentially, not linearly, so does the rate of change -- and that means the next 10 years should pack in far more technological change than the last 10.

Disruptive technology is, by its very nature, unpredictable, but it is still possible to look at the work being done by R&D labs around the world and see clues as to what the future holds. That's the full-time job of Dave Evans, Cisco's chief futurist and chief technologist for the Cisco Internet Business Solutions Group (IBSG).

At Cisco Live, Evans outlined what he believed to be the top 10 trends that will change the world in 10 years.

Ahead of the Curve

Curve Dental is about to be the first web-based PMS to have a real-time image module. The new module will be released in 5 days. Here's the info:



Curve Dental's New Web-based Digital Imaging Technology Poised to Change How Dentists Capture, Store and Access Patient Information



OREM, UT— Curve Dental, developers of Web-based dental software, announced the completion of new digital imaging features, which allow doctors and staff to capture x-ray and intraoral images directly to the cloud. The technology developed by Curve Dental, which is the first of its kind in dentistry, provides doctors with a digital imaging solution that is entirely web-based. Using the cloud to capture and store patient images eliminates the need for a server, affords unlimited storage and a proven backup and business continuity solution, and provides the dentist with access to the data from any computer with Internet access at anytime from anywhere.



“Our digital imaging features are revolutionary within the dental profession,” said Matt Dorey, Founder and Managing Director of Curve Dental. “With our software a doctor only needs a computer with Internet access and a browser to capture digital images. They don’t need a server, powerful and expensive hardware, nor do they need to worry about backups or space limitations. Moreover, our strategy is to allow doctors to connect any digital x-ray sensor, intraoral camera, or digital panoramic imaging system to our software, which is an advantage to the dentist because most dental professionals already have these types of digital devices in their practices. Switching to our software shouldn’t require the dentist to invest in new digital devices; that is our goal.”



Compatibility with as many different digital devices as possible is Curve Dental’s strategy. Currently the software is compatible with the Schick, Suni, Gendex, Eva, and Owandy digital x-ray sensors and will soon be compatible with the Kodak sensor. Additional compatibility will be added as quickly as possible. TWAIN-compatible intraoral cameras and panographs will connect directly with the software now, but may require the dentist to install additional drivers supplied by the manufacturer.



Curve Dental’s imaging software is native to its practice management software using a single database and set of code, which provides the doctor and staff with a consistent look and feel throughout the software. Native code also makes the software easier to learn and less demanding on a practice that must train new team members. A stand-alone version of the imaging software will also be available in the near future. “Because our imaging software is ‘native’ to our practice management software it is more efficient and more stable than an integrated or bridged solution,” says Dorey. “‘Integrated’ or ‘bridged’ solutions equate to separate databases, separate sources for technical support and two applications that may work and look differently from each other.”



Curve Dental recommends a DSL or faster Internet connection. “With digital imaging the user experience is enjoyable on almost any high-speed Internet connection,” says Dorey. “We focused our attention on processes and efficiencies to make sure the image could be compressed quickly, without changing or degrading quality, and uploaded to the cloud instantly. We’re happy with the results and our customers are finding the experience to be comparable to capturing and saving an image locally.”



Like the company’s practice management features the imaging features are sold on a subscription basis with an additional setup fee. Introductory pricing is being offered until the end of the year. Interested parties should call for additional information. Although Curve Dental has received FDA approval for US dentists, Health Canada approval is still pending. Canadian dentists are not able to use the imaging features yet.

Freefall

While I never advocate free antivirus software for dental offices (most of them are illegal to install in an commercial setting like a dental practice), there's no reason to spend an arm and a leg for the antivirus software you use at home. Here are The Best Free Antivirus Software programs.

Pass the Torch

One of the most convenient tools browsers offer is the ability to save and automatically prefill your passwords on login forms. Because so many sites require accounts and it is well known (or should be at least) that using a shared password is a big no-no, a password manager is almost essential.

So if you are an IE user and answer “yes” to allow the browser to remember your password, how secure is this information?

Goliath vs. Goilath

Google is gunning for Facebook.

The search giant recently launched Google+, a social networking site that aims to rectify the company's failed social media efforts, such as Google Buzz and Wave, and put a dent in Facebook's business.

So does Google+ stand a chance against Facebook, which is now over 750 million users strong and has been valued at $100 billion? Google isn't giving up without a fight: the behemoth needs a hit in the social space and one Google executive called Google+ a bet-the-company effort. To help you decide, here's a look at six features Google+ has that Facebook doesn't.

Hide in Plain Sight

There are lots of people who prefer to browse the internet using a proxy. There are many reasons behind it. One of the most important reasons include your private information which you may just leave on a public computer.

When you browse the internet through hidden proxies, websites do not send you the request directly but to the proxy server and it shows the information of the proxy server rather than your personal information. They are also used to unblock websites on different organizations and school networks like Facebook, Twitter etc.

For that purpose, here's a list of 10 excellent free proxy services which you can use to browse the internet anonymously.
