नई दिल्ली : पहले बड़ों की बीमारी मानी जाने वाली टाइप- 2 डायबीटीज अब बच्चों को भी होने लगी है। आमतौर पर टाइप- 2 डायबीटीज का खतरा 40 की उम्र के बाद माना जाता है, लेकिन अब 13 साल की उम्र से ही इसके लक्षण दिखने लगे हैं। 15 - 16 की उम्र तक पहुंचते-पहुंचते तो समस्या बड़ी बीमारी का रूप ले लेती है। चिंताजनक बात यह है कि इससे सिर्फ हेल्थ ही नहीं बल्कि लुक भी प्रभावित हो रहा है।

 

हार्ट केयर फाउंडेशन के अध्यक्ष डॉ. के. के. अग्रवाल का कहना है कि फिलहाल बच्चों में डायबीटीज की समस्या कितनी बड़ी है? यह पता करने के लिए बड़े लेवल पर स्टडी नहीं हो पाई है, मगर वर्ल्ड हेल्थ ऑर्गनाइजेशन जैसी एजंसियों के अनुमान के मुताबिक फिलहाल शहरी क्षेत्रों में रहने वाले 33 से 37 फीसदी स्कूली बच्चे मोटापे के शिकार हैं। इनमें से 10 फीसदी से ज्यादा डायबीटीज की चपेट में आ चुके हैं और लगभग इतने ही प्री-डायबिटिक स्टेज में हैं। डॉ. अग्रवाल के मुताबिक गलत जीवनशैली या पारिवारिक इतिहास के चलते होने वाला टाइप-2 डायबीटीज का असर लड़कों की तुलना में लड़कियों में डेढ़ फीसदी ज्यादा हो रहा है। इसके कारण लड़कियों के पीरियड्स में अनियमितता या मूछें उगने जैसी दिक्कतें हो रही हैं। इससे कई तरह की फिजिकल और साइकलॉजिकल समस्याएं भी पैदा हो रही हैं।

 

दिल्ली डायबिटिक रिसर्च सेंटर के अध्यक्ष डॉ. ए. के. झिंगन के मुताबिक, कम उम्र में टाइप-2 डायबीटीज होने के कारण मोटापा और इंसुलिन से संबंधित समस्याएं आम हैं। इसके कारण कम उम्र में ही हार्ट, किडनी और लीवर की बीमारियों का खतरा कई गुना बढ़ जाता है। इंडियन हार्ट फाउंडेशन के अध्यक्ष डॉ. आर. एन. कालरा का कहना है कि इस तरह की दिक्कतों से बचाव के लिए बच्चों में शुरू से ही चीनी, चावल, मैदा जैसी चीजों से परहेज रखने और देर रात तक न जागने की आदत डालें। साथ ही उन्हें फिजिकल एक्सरसाइज के लिए भी भेजें।

 

डायबीटीज ने बढ़ाया आंखों के लिए भी खतरा

 

डायबीटीज आंखों की रोशनी के लिए भी सबसे बड़ा खतरा बन गया है। इसके कारण डाबिटिक रेटिनोपैथी नाम की बीमारी हो जाती है। ऐसा कहना है सेंटर फॉर साइट के डायरेक्टर डॉ. महिपाल सचदेव का। उन्होंने बताया कि डायबिटिक रेटिनोपैथी में रेटिना की ब्लड वेसेल्स कमजोर हो जाती हैं और इनसे खून निकलने लगता है। इससे नसें सूज सकती हैं।

 

इस तरह के बदलावों से रेटिना के अंदर ब्लड का संचार सामान्य नहीं रहता और आंखों को ऑक्सिजन और अन्य न्यूट्रिएंट नहीं मिल पाते। श्रेया आई सेंटर के अध्यक्ष डॉ. राकेश गुप्ता कहते हैं कि जैसे-जैसे यह बीमारी बढ़ती है वैसे-वैसे आंखों की रोशनी कम होती जाती है। ऐसे में शुरू से बचाव और समय पर आंखों की जांच बहुत जरूरी है।

Defcon: Excuse me while I turn off your pacemaker

Defcon: Excuse me while I turn off your pacemaker

August 8, 2008 Dean Takahashi

The Defcon conference is the wild and woolly version of Black Hat for the unwashed masses of hackers. It always has its share of unusual hacks. The oddest so far is a collaborative academic effort where medical device security researchers have figured out how to turn off someone's pacemaker via remote control. They previously disclosed the paper at a conference in May. But the larger point of the vulnerability of all wirelessly-controlled medical devices remains a hot topic here at the show in Las Vegas.

Let's not have a collective heart attack, at least not yet. The people on the right side of the security fence are the ones who have figured this out so far. But this has very serious implications for the 2.6 million people who had pacemakers installed from 1990 to 2002 (the stats available from the researchers). It also presents product liability problems for the five companies that make pace makers.

Kevin Fu, an associate professor at the University of Massachusetts at Amherst and director of the Medical Device Security Center, said that his team and researchers at the University of Washington spent two years working on the challenge. Fu presented at Black Hat while Daniel Halperin, a graduate student at the University of Washington, presented today at Defcon.

Getting access to a pacemaker wasn't easy. Fu's team had to analyze and understand pacemakers for which there was no available documentation. Fu asked the medical device makers, explaining his cause fully, but didn't get any help.

William H. Maisel, a doctor at Beth Israel Deaconess Hospital and Harvard Medical School, granted Fu access for the project. Fu received an old pacemaker as the doctor installed a new one in a patient. The team had to use complicated procedures to take apart the pacemaker and reverse engineer its processes. Halperin said that the devices have a built-in test mechanism which turns out to be a bug that can be exploited by hackers. There is no cryptographic key used to secure the wireless communication between the control device and the pacemaker.

A computer acts as a control mechanism for programming the pacemaker so that it can be set to deal with a patient's particular defribrillation needs. Pacemakers administer small shocks to the heart to restore a regular heartbeat. The devices have the ability to induce a fatal shock to a heart.

Fu and Halperin said they used a cheap $1,000 system to mimic the control mechanism. It included a software radio, GNU radio software, and other electronics. They could use that to eavesdrop on private data such as the identity of the patient, the doctor, the diagnosis, and the pacemaker instructions. They figured out how to control the pacemaker with their device.

"You can induce the test mode, drain the device battery, and turn off therapies," Halperin said.

Translation: you can kill the patient. Fu said that he didn't try the attack on other brands of pacemakers because he just needed to prove the academic point. Halperin said, "This is something that academics can do now. We have to do something before the ability to mount attacks becomes easier."

The disclosure at Defcon wasn't particularly detailed, though the paper has all of the information on the hack. The crowd here is mostly male, young, with plenty of shaved heads, tattoos and long hair. The conference is a cash-only event where no pictures are allowed without consent. It draws thousands more people from a much wider net of security researchers and hackers than the more exclusive Black Hat.

Similar wireless control mechanisms are used for administering drugs to a patient or other medical devices. Clearly, the medical device companies have to start working on more secure devices. Other hackers have figured out how to induce epileptic seizures in people sensitive to light conditions. The longer I stay at the security conferences here in Las Vegas, the scarier it gets.

Philips iPill -- Like a Regular Pill, But With a Microprocessor

It's been just about a year since we saw the patent for Philips' remote control "pill," and it looks like the thing is finally a reality. For those of you straining to remember that far back, the iPill (as it is now sadly known) is a miniature capsule that among its many charms contains a microprocessor, power supply, medicine reservoir and pump, and a radio so that it can remain in contact with external medical equipment. The pill's ability to accurately determine its position in the digestive tract enables it to deliver drugs precisely where they're needed, reducing dosage strength and side effects. According to Philips, the current design is a prototype, but it's suitable for serial manufacturing. Of course, this is not the first robot
pill we've seen -- and it certainly won't be the last. Just the same, we think we'll refrain from swallowing any nanotech for the time being.

Crawling robot pill

by Katie Fehrenbacher posted Oct 7th 2004 at 2:51AM

While the initial response to the idea of a leggy robot crawling around your guts is naturally one of shock and awe, but if you really think about the other surgical and endoscopic options, they're all a little offputting as well: tubes, little cameras on wires, so why the hell not a tiny-legged robot pill? The 25mm long and 10mm diameter crawling capsule was created by researchers in Italy and Korea and once the pill is swallowed the soft coating dissolves and the crazy-legged robot starts its course. The only issue might be one of control, since we're sure the patient won't be none too pleased when some rogue robot goes starts aimlessly inspecting his intestines.
