1 Diabetes and The Internet October 2005 Jeff Hitchcock Children with Diabetes Finding Resources You and Your Health Care Team Can Trust

2 Agenda Internet Content –Determining quality is a challenge –Web sites, Mailing lists, Newsgroups, Other Services –Privacy and Security Concerns Searching for Answers –Web sites, Search engines, PubMed Vetting the Good from the Not So Good remains a challenge Security issues While people often think that the Internet and the World Wide Web are the same, there is more on the Internet than just web sites. Diabetes information and support can be found throughout the Internet. Topics for Todays Discussion

3 Determining Quality Thousands of web sites about diabetes –Few are supported by medical professionals –Most are not kept up to date –Some are marketing dubious products Look for trusted sources (HONcode) –Check credentials (look for an About page and read it carefully) –Look for sponsorships that might cause bias Be skeptical –Just because its on the Internet doesnt mean its true –If it seems too good to be true, it probably is Ask yourself, Why does this site exist? When in doubt, ask your Diabetes Team Quality varies greatly throughout the Internet Quality and accuracy do not always go hand in hand. There are many well done web sites hawking vitamins, minerals, even fruits, as a cure for diabetes. There are also modest sites that have excellent content.

4 Web Sites Major diabetes web sites –Children with Diabetes ( –NIDDK ( –American Diabetes Association ( –Juvenile Diabetes Research Foundation ( –Canadian Diabetes Association ( –David Mendosas Diabetes Directory ( Good starting points on the World Wide Web When you seek information on the Internet, start with names you know and trust. Searching for diabetes on Google yields 88 million results.

5 Web Sites Corporate web sites have become excellent patient education and marketing tools. Examples: –Meter Companies Abbott Diabetes Care ( LifeScan ( Accu-Chek ( –Pump Companies Animas ( Smiths Medical Deltec ( Medtronic MiniMed ( –Insulin Companies Novo Nordisk ( Aventis ( Lilly ( Many companies have excellent web sites Company websites are a great place to learn about the latest diabetes products. Some sites include virtual models of their products, such as glucose meters and insulin pumps. Many offer products manuals online in PDF format in case youve lost yours.

6 Web Sites Many clinics have established web sites to provide information and reach out to their patients –Barbara Davis Center for Childhood Diabetes ( –Diabetes Research Institute ( –Joslin ( Many clinics have excellent web sites Some clinic sites help you understand the science behind diabetes research and the best in todays clinical practice guidelines. Learn about islet cell transplantation at the DRI web site, for example.

7 Web Sites There are many government run web sites with diabetes information, including –NIDDK ( General diabetes information Everything is free for use –FDA ( Regulatory information about drugs and devices Report adverse events online –PubMed ( Search millions of journal articles Keep up to date Verify claims of miracle cures The US Government offers several excellent web sites All information on US Government web sites is in the public domain and can be copied or used as needed without requiring permission.

The parents mailing list at Children with Diabetes often generates 200 or more messages per day. Online archives help people keep up- to-date.

32 Newsgroups Usenet newsgroups offer threaded discussions Two main diabetes groups: – Focus on adults and adult issues (mostly Type 2) – Focus on adults and adult issues (Type 1 and Type 2) Always read the FAQ ( Be wary of disguised commercial posts The alt hierarchy is sometimes not available Families should be very careful about permitting unrestricted Usenet access due to easy access to vast amounts of objectionable content Usenet is home to tens of thousands of discussion boards Before the World Wide Web, Usenet was responsible for a large percentage of Internet traffic. Its importance has declined in recent years, due in large part to unwanted commercial postings in all newsgroups.

33 is a major Usenet location for diabetes support.

34 Searching for Answers The Web offers unparalleled access to information Information rich web sites offer internal search capability Search engines search across multiple web sites PubMed houses journal abstracts from the National Library of Medicine The Web is a true global source of information The Web is a great equalizer, offering the same information to everyone who has access to a computer.

35 Searching Web Sites Content rich web sites often offer internal searches Search results will be limited to that web sites content Dynamically generated content is usually only searchable this way –The Family Support Network at CWD can help you find a friend, babysitter, or family near your child off at college –The Schools database at CWD, which reports on blood testing policies at public schools in the US Search web sites for the information you want Search tools are readily available for Web Masters, and some of the best are free.

36 CWD Search Results Example Search results from NovoLog at CWD finds lots of matches, listed in order of relevance. Search terms are highlighted in yellow to help you find what youre looking for.

37 Search Engines Search engines can help you find diabetes web sites Search engine ratings vary, so results of searches vary Recommended starting points: –Google ( Rankings based on how many other web sites link to the site that is indexed 88 million hits for diabetes –Google Scholar ( Search scientific journals –Yahoo ( An index, rather than a search engine Search engines index billions of web pages Beware of search engine bias, especially if you use your ISPs proprietary search tool. Google is a good place to start, though diabetes by itself is not helpful.

38 Search Engine Example – Google How do you begin to make sense of 88 million search results in Google? The links on the right are paid ads, not necessarily content that best meets your search words.

39 Yahoos Diabetes Directory Yahoo! is a directory, not a search engine. CWD is ranked as the most popular diabetes web site.

40 PubMed – PubMed is the gateway into MEDLINE, an archive of millions of scientific journal articles.

41 Searching PubMed Over 12 million MEDLINE citations Searchable by keyword, author, journal Abstracts of journal articles generally available Very few journals allow free access to full text articles An understanding of statistics can help you read the abstracts Online at PubMed offers a window into the world of science If you want to read current science, PubMed is the place to start.

42 PubMed Search Results Search results in PubMed link to abstracts of articles. From there, many link to journal publishers web sites where consumers can pay to view a full-text document.

43 Assessing Web Sites Data shows that a large majority of people use the Internet to search for health care information Separating good from bad is essential for your health Simple things to look for: –Clear ownership and contact information –CVs of content authors –Proper citations to trusted sources for medical claims –Lack of claims for miracle cures or untested treatments –High content-to-sales-pitch ratio When in doubt, ask your Diabetes Team Separating the good from the not so good Always consider the goal of the web site owner. Is it only there to sell you something, or is there product- neutral content of value?

44 Health on the Net Foundation Health on the Net Foundation ( Offers 8 Principals for medical web sites Goal is to ensure authority, confidentiality, appropriate attribution, justifiable claims, transparency of authorship and ownership, and honesty in advertising Look for the HONcode logo, which links to the HON web site: HON, based in Switzerland, helps consumers find medical web sites that they can trust. Since 1996, HON has been vetting medical web sites

45 HON Link Example Web sites that follow the HONcode are noted at the HON web site. This example shows that CWD is in compliance and has been since HONs founding in 1996.

46 QuackWatch – While there are many excellent diabetes-related web sites … … there are many that are not so excellent Claims of miracle cures, toxic food additives and the like should be viewed with extreme skepticism If there were a cure, your Diabetes Team would tell you How to Spot a Quacky Web Site is a great place to start ( ) If something seems too good to be true, it probably is. Check out QuackWatch. QuackWatch is run by Stephen Barrett, M.D.

47 QuackWatch QuackWatch offers a wealth of information about pseudo cures and bad medical advice on a great many topics.

48 Privacy and Security How to use the Internet safely Privacy issues Computer security issues These are issues that cannot be ignored by anyone using the Internet Most at risk are users of DSL and cable modems, but … … even dial-up users are at risk Privacy and security go hand- in-hand and are the foundation of safe use of the Internet. Parents can no longer trust their kids to keep the computer safe. The Internet is like the Wild West

49 Everything you do on the Internet can be tracked, recorded, analyzed, and used in ways you did not intend. Remember that as you surf the Web. Privacy will become a critical issue as Internet use increases Privacy Concerns Medical information is sensitive information Keep privacy in mind whenever you can Look for privacy policies on web sites –Who owns the web site? –What is done with web site access logs information? –What is done with personal information? –What is done with other information, such as chat room messages? New HIPAA rules govern storage of personally identifiable medical data Be especially careful of childrens use of the Internet

50 Privacy in General Get an e-mail address at a free service such as cwdMail ( or Yahoo Mail ( –Use that e-mail address for anything public, especially posting to Usenet –You can always delete it and start over –NEVER reply to spam –NEVER buy anything advertised in spam Create a screen name for yourself Supervise children while they use the Internet Place the home computer out in the open Be careful giving out personal information Dont disclose what you dont want to You can always make it up There are ways to maximize your privacy Unsolicited commercial e-mail, called spam, has become one of the most serious problems facing the Internet. Data indicates that up to 80% of all e-mail is spam. Some spam verifies your address without your response – so called web bots.

51 Privacy on Usenet There is no privacy on Usenet –Google Groups archives Usenet Hundreds of millions of messages archived –Everything you say will be preserved for all to see –Think twice before sending any message to Usenet –Employers routinely screen Google Groups for messages posted by prospective employees Never post your real e-mail address on Usenet –If you post your e-mail address on Usenet, you will receive unsolicited commercial e-mail (spam) –Many spam messages are for pornographic web sites or get-rich-quick frauds Tread carefully into Usenet if you value your privacy With web sites offering a richer experience than Usenet, most Internet users have never even heard of newsgroups.

52 Privacy on the Web Virtually all web sites track where you came from Many web sites use cookies to track your progress through the web site –Cookies are helpful in remembering login information –Cookies can help a web site do a better job for you –Cookies also represent a security risk Be very skeptical of what you read –Anyone can publish a web page –Look for credentials of owners –Think, Whats in it for the web site owner? Look for a privacy policy page and read it Look for a privacy policy on web sites you visit Before you register on a web site, ask yourself, Will the benefits I receive be worth the loss of privacy?

53 Computer Security Security is no longer optional and it cannot be deferred Five requirements: –Up to date anti-virus software –Operating system patches applied as soon as they are available –Run a firewall –Never install software from an untrusted source, and an email from a friend is not trusted –Never respond to or buy anything advertised in spam Always on connections (DSL and cable) are most at risk but … … even a dial-up connection can be infected in seconds if not protected Every computer exposed to the Internet is at risk for compromise. Unprotected systems can be taken over in seconds and will certainly be compromised within hours. If you need help, attend a computer class

54 What are the risks? Email viruses –Primarily exploiting Outlook and Outlook Express on PCs –Usually requires the recipient to open the message –New tactic is to use social engineering Operating system vulnerabilities –Simply connecting to the Internet exposes the computer to compromise Spyware / Malware –Applications that take over Internet Explorer or install background programs –Pop up ads, transmit your personal data to program authors Windows PCs represent the greatest target for security compromise, simply because of market share. But every system is vulnerable if not protected properly. Everyone online is at risk

55 What can happen? Viruses / worms turn your computer into a spamming machine –Your computer unwittingly sends millions of porn, fraud, or other spam messages –Your ISP detects the problem and cancels your account Spyware / Malware shares your private data –Browser hijacked to display marketing messages instead of real information youre seeking –Background applications search your computer for personal data and upload it to the spyware author –A recent survey by the National Cyber Security Alliance found that nearly 90 percent of all personal computers could be infected with at least one form of spyware. (Wired News, 5/7/2004) Both place you at great risk for identify theft Children should never be permitted to install any software on a computer without a parent supervising. Create limited access accounts for kids, even teens, and do not share your administrative password. Repairing a compromised computer can take hours to days

56 How can you get infected? File sharing applications, such as Kazaa, come bundled with spyware applications Online game applications downloaded from the Internet Games and other applications purchased at flea markets and computer fairs Pirated programs downloaded from the Internet Paid for browsing applications Paid for spare computing time applications If its free, chances are it comes with spyware Free software rarely is and the true cost of accidentally installing spyware can be enormous – including identity theft. Rule of thumb: Only install software you buy at a computer store

57 Windows Update Every Windows user should enable automatic updates to ensure that security fixes are installed as soon as they are available. Windows vulnerabilities can result in a compromised system without ever opening email or visiting a web site.

58 Symantec Security Advisories Symantec, maker of Norton Anti-Virus, publishes lists of current virus threats and other risks to computer users.

59 Firewalls The purpose of a firewall is to protect your computer or network Firewalls block unsolicited communications to your computer Firewalls can be programmed to permit only specific incoming communications Firewalls help reduce the risk from operating system exploits All new routers (DSL, cable, wireless) have firewall capabilities built in Think of a firewall as a body guard for your computer, always there to stop the bad guys from getting in. Always on connections require a firewall

60 Microsoft XP Built in Firewall The firewall built into Windows XP is a great place to start. Enable it to prevent unsolicited communications to your computer.

61 Router Firewalls Enable the firewall in your DSL or cable modems router for protection against Windows exploits.

62 Operating System Security Resources Microsoft ( –Excellent resource for PC users Apple ( –Unfortunately, marketing piece for OS/X Keep up to date with your systems security fixes. Its essential. All software has bugs, including operating systems

63 Spyware Resources Microsoft Spyware Page ( ware/default.mspx ) AdAware ( –Removes spyware and malware –Free LavaSoft Support ( –Searchable forum to find out about spyware and malware infections –Learn about ways to fix compromised computers Computer Cops ( –Excellent source for fixing compromised machines Spyware and malware infections represent serious compromises of your computer. Everything on it can be handed over to criminal gangs. Spyware accounts for about half of all technical support calls to Dell

64 Spam Unsolicited commercial email is called spam, taken from a Monty Python skit. Heres an example of a spam sent on Friday, May 7 th, indicating that I had applied for a mortgage. Lets look at this message in more detail.

65 Spam – Headers Return-Path: Received: from ([]) by (Post.Office MTA v3.5.3 release 223 ID# 0- 57478U300L100S0V35) with ESMTP id com; Fri, 7 May 2004 05:26:21 -0400 Received: from (cbl217-132-107- []) by (Postfix) with SMTP id EBD0418E702; Fri, 7 May 2004 05:24:13 -0400 (EDT) Received: from by; Fri, 07 May 2004 07:25:06 -0300 Message-ID: From: "Alison Fountain" Reply-To: "Alison Fountain" To: Cc: Subject: Important Information about your house Date: Fri, 07 May 2004 12:26:06 +0200 MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="--84517076440321792176" X-Webmail-Time: Fri, 07 May 2004 16:24:06 +0600 The full mail headers show the actual source of the spam, plus lots of fraud. The only thing we know for sure is that this spam originated in Israel from an ISP called Netvision. It probably came from a computer that is infected with a worm that has been turned into a spamming zombie. Forged headers are common in spam

66 Spam – Spammer Domain The web site listed in the spam was created on April 29, 2004 by someone in Shanghai, China. How likely is it that an American obtained a home loan from a company in China? Would you want to send personal information to someone you dont know in China? Domain Name: LOANSAVINGSCLUB.COM Registrant: Lincom Co.,LTD ZHANG SHUSHENG ( Room C, D,Fl 19 No. 618 YAN AN RD.(East) SHANGHAI SHANGHAI,200001 CN Tel. +86.2163854111 Creation Date: 29-Apr-2004 Expiration Date: 29-Apr-2005 Domain servers in listed order: Investigate domains using the Geektools web site at Many spammers have moved their domains outside the US

67 Spam – Spammer Web Site The spammers web site is hosted in Shijiazhuang, China. Is your mortgage loan broker there? How many of you even know where that is? Name: Address: person:Bin Ren nic-hdl:BR3-AP address:10F Ximei Building NO.6 Jianshe South Street address:Shijiazhuang 050011 China phone:+86-311-5211551 fax-no:+86-311-5211578 country:CN 20040430 mnt-by:MAINT-CHINATELECOM-HE source: APNIC Tracking down the real spammer is very difficult

68 Summary The Internet offers a vast amount of information about diabetes There are hundreds of diabetes-related web sites, some large, some not so large Good medical information is available on the Internet Be cautious when you find web sites promising miracle cures Protect your privacy as much as you can Consult with your diabetes team before you make any changes to your diabetes care Always practice safe computing Knowledge is power in diabetes management
