      Doctor Who Restored the Vision of More Than 100,000 people

    • It takes Sanduk Ruit about five minutes to change someone's life. In that time, the Nepalese doctor can make a small incision in his patient's eye, remove the cloudy cataract impairing her vision and replace it with an inexpensive artificial lens. "Some of our younger surgeons even do it faster than that," Ruit told CNN. For many patients, it's the first time they've seen in years, if not decades. In the past 30 years, Ruit has personally restored the sight of more than 100,000 people across Asia and Africa, and taught his rapid-fire technique to countless other eye surgeons in parts of the world as isolated as North Korea. His patients suffer from eye conditions that are mostly preventable. But because of poverty and limited access to public health services they have been unable to seek treatment. Their story is all too common in the developing world. An estimated 39 million people are blind worldwide, according to the World Health Organization. Of these, around 90% live in low-income areas and 80% suffer from conditions that can be prevented or cured. Reaching remote communities Driven by a belief that the world's poorest people deserve safe, affordable and high-quality eye care just as much as anyone else, Ruit has made it his mission to eradicate avoidable blindness. In 1994, he joined the late Australian ophthalmologist and philanthropist Fred Hollows, who was his mentor and close friend, in establishing Tilganga -- an eye hospital in Kathmandu dedicated to providing world-class eye care to the people of Nepal. The hospital manufactures state-of-the-art lenses that are commonly used in treating cataracts or myopia, and exports them to more than 30 countries worldwide. For those who cannot reach urban areas, Ruit and his team conduct mobile eye camps in remote parts of Nepal and neighboring countries, often trekking for days and cleaning out structures like tents, classrooms or even animal stables for use as temporary operating theaters. When the eye patches come off the day after an operation, it's an incredibly moving moment for all involved. Australian photographer Michael Amendolia has been capturing these intimate scenes -- the expressions of relief and tears of joy -- while traveling with Ruit and his colleagues since the early 1990s. To mark the 20th anniversary of Tilganga, Amendolia has released some of his most striking images of Ruit and his team at work in Nepal and other countries in the region, including Bhutan, China, Myanmar, North Korea and Indonesia.

      These 20 One-Liners Come Straight from the Doctors’ Notes

    • The reality is doctors often feel short of words while noting down history. Its not easy task to convert everything what patients say into doctors notes. This is what happen when you're  too busy in the OPD Patient has left her white blood cells at another hospital. Patient has chest pain if she lies on her left side for over a year. On the second day the knee was better and on the third day it disappeared. The patient has been depressed since she began seeing me in 1993. Discharge status: Alive, but without my permission. Patient had waffles for breakfast and anorexia for lunch. While in ER, Eva was examined, x-rated and sent home. Skin: somewhat pale, but present. Patient has two teenage children, but no other abnormalities. The patient was in his usual state of good health until his airplane ran out of fuel and crashed. Mrs. Evans slipped on the ice and apparently her legs went in separate directions in early December. Patient was seen in consultation by Dr. Jones, who felt we should sit on the abdomen and I agree. The patient refused autopsy. The patient has no previous history of suicides. She is numb from her toes down. She stated that she had been constipated for most of her life until she got a divorce. Both breasts are equal and reactive to light and accommodation. Examination of genitalia has revealed that he is circus-sized. Patient was found in bed with her power mower. She has no rigors or shaking chills, but her husband states she was hot in bed last night.
      Medical Students Guide: How to Study Less by Learning Things Once

    • You read over your notes. Then you read them over again. Then you read them over a third time. Then you take the test and are surprised at just how much you missed. Despite reading everything three times!   A lot of study time is wasted because of one problem: you fail to learn things the first time around. Repeatedly going over the same information like putting a band-aid over a sieve. It may reduce the water that slips through, but it doesn’t solve the fundamental problem: that you have too many holes. The key to reducing the amount of time you study is simple: learn things the first time you see them, instead of after dozens of repetitions. This is all easier said than done. I’m sure if your mind was without holes you could easily capture any information that slipped into it. The real question is how can you do this? I don’t believe it is just a matter of being a genius or chance, but based on how you study. Step One: Find the Holes If you want to repair a leaky brain, you need to figure out where the holes are. Identify what type of information you have trouble remembering. Recognize when you’ve just gone over information you don’t quite understand. Here’s a few questions to ask yourself after every chunk of ideas to find your holes: What from this section am I most likely to forget? What concepts are completely new to me? (Rather than ones that feel familiar) Which ideas am I having the most difficulty grasping? When you identify weak points, you can invest more time in fixing those instead of wasting time with a blanket studying technique of all information. Step Two: Repair Weak Points Once you’ve identified potential weak-points, you should immediately seek to fix them. Drop everything your doing and seek out a fix for the problem. Programmers understand that a bug left in the system can create several hundred times the cost to fix it later. As a learner, you need to understand that the same principle of fixing problems quickly also applies. There are hundreds of books written on various strategies to fix weak points, which is a bit outside the scope of this quick article. But here are a few starting points: Memorizing? If you need to store arbitrary information, try using the link method. This is where you visualize an exaggerated image that combines the two things you want to associate. You can memorize formula’s this way by linking vivid pictures to the different symbols. A formula such as F = C/A, could become a scale with hundreds of (F)eathers on side and a giant (C)aterpillar sitting over millions of (A)nts. Conceptualizing? If you need to understand information try drawing a picture or diagram to combine the ideas. Retaining? If you need to retain a complicated mass of information try using metaphors and vivid examples to connect the abstract information into something you can easily relate to. Repairing weak points in your understanding isn’t that difficult – if you first know where they are. Simply focusing on a piece of information can help you understand it. But if you don’t know which parts you’re missing, it is easy to skim over everything and not realize what you’ve missed. Step Three: Check Your Understanding Do you “get” it. Does the information make sense to you at a deeper level, or does it seem arbitrary, meaningless or difficult to derive? Most school tests and virtually all real-life tests are designed to answer a single question: do you understand what you’re studying? If you aren’t sure, that’s when you need to start working deeper. Keep asking yourself “why” until you reach a point where the subject makes sense. Here are some tips for improving your understanding: Look for sensory descriptions.Your brain isn’t a computer. It’s designed to retain emotional, vivid and sensory information better than abstract or dry details. Link a sensation, picture or story to the abstract details. When learning how to do determinants (a form of math using matrices) I imagined my hands moving through the diagonals, one adding and one taking away. Get the background. A lot of information that seems meaningless makes more sense when given a context. If your stuck on trying to wrap your head around a particular point, do some research into it’s origins. This may take more time up-front, but can save hours as future concepts are built upon it. Step Four: Test Yourself Whenever you’re experimenting with new learning methods, you need to measure the results. Check to see whether your new system is actually helping you remember more. Once you get familiar with a system, you can more accurately judge the extent of your knowledge. But until then, test regularly so you can tweak the system to fix errors. The best tests are objective ones. If you’re in school, look for past exams, tests or textbook questions to check your understanding. If you’re teaching yourself, come up with short exercises that can prove to you conclusively you know what you’re doing. The most important piece of advice I can give is this: treat study time as being sacred. Go in with the expectation that you will either learn everything through the first go, or you will identify areas that need further clarification. Focus and become aware of any potential holes so you can learn things once.

      Who can go for LASIK eye Surgery?

    • LASIK is a surgical methodology that uses a laser to correct partial blindness, farsightedness and astigmatism. The LASIK surgery is done by an ophthalmologist who utilizes a laser to reshape the eye's cornea, keeping in mind the end goal to enhance visual acuity. For most patients, LASIK gives a lasting alternative to contact lenses or eyeglasses. LASIK can likewise adjust astigmatism by smoothing an irregular cornea into a more usual shape. If you are thinking about LASIK eye surgery, your initial step is to pick a decent LASIK specialist who can assess whether LASIK is appropriate for you. Your LASIK specialist will analyze your eyes to decide their health, what sort of vision revision you need, and how much laser ablation is required. LASIK is most like any other surgical remedial methodology, photo-refractive keratectomy (PRK). As per the year 2011, more than 11 million LASIK methods had been performed in the United States in 2009 more than 28 million have been performed around the world. ELIGIBILITY FOR A LASIK EYE SURGERY: LASIK surgery is a kind of refractive eye surgery. Amid the strategy, an eye specialist makes a flap in the cornea and later on uses a laser to reshape the cornea and correct the refractive issues in the eye. LASIK surgery is suitable for the individuals, who have a direct level of refractive error, causing: Astigmatism, in which you see nearby objects, yet far off objects are hazy. Farsightedness (hyperopia), in which you can see far things easily but nearby things is blurry. A decent surgical result relies upon cautious assessment of your eyes before the surgery. To be qualified for LASIK surgery, potential applicants must meet the accompanying criteria: AGE - Candidates must be no less than 18 years of age. GENERAL HEALTH - LASIK applicants must be in good health and should not have certain medical issues, including uncontrolled diabetes, collagen vascular illness, or take any pharmaceutical. EYE HEALTH - Candidates ought to be free of eye ailments including keratoconus, glaucoma and certain retinal and optic nerve diseases. EYE INJURY - Patients should not have any eye diseases. DRY EYE CONDITION - Patients should not persistently experience the ill effects of dry eyes. STABLE VISION - The vision of the candidates must be steady for no less than one year prior to the procedure date. CONTACTS - Prior to your LASIK surgery consultation and LASIK strategy, you should not wear contact lenses for a specific time. The exact length will be controlled by your specialist on an individual basis. This guarantees corneal soundness and precise evaluation of your prescription prior to the LASIK surgery methodology. NURSING/PREGNANCY - Candidates should not be pregnant or nursing while experiencing the LASIK procedure. Hormones may influence the strength of your prescription, so pregnant or nursing ladies are not qualified to seek LASIK surgery until three menstrual cycles in the wake of nursing has been ceased. These are some of the points which show if you can go for a LASIK eye surgery or not. Via Lasik Eyes Surgery 
      High Numbers of MRI Machine accidents :Are we defaulters?

    •                  Many operational considerations for MR imaging are similar to those for CT. Differences occur because of fringe magnetic fields, radio frequency shielding, geometry of the magnet bore, and lack of known biological hazard with MR imaging.  The magnet is always on, especially in an MRI that is high-filled 1.5 Tesla or higher. This is so that the cooling of the superconducting magnet can take place and maintain an effective electromagnetic field for image acquisition. If there is some sort of incident or injury that requires a "quench" or purge of the coolant in order to turn off the magnet, the liquid helium must be vented quickly and safely directly into the atmosphere. This is why MRI machines are often on upper floors of hospitals, especially older hospitals. Liquid helium is super expensive and to quench and replenish takes time and lots of money. This is why you can also find videos on YouTube and such of people trying to pry office chairs out of an MRI with two by fours and other non ferrous items.                Ignoring Standard recommendations to setup an MRI machine not only caused malfunctioning or low quality imaging, its a life hazard. There were several instances in the recent past, when people and equipment were stuck inside MRI.                    Nevertheless, a patient’s condition can deteriorate during MR imaging, requiring emergency intervention. MR imaging systems can interfere with both patient monitoring and cardiopulmonary resuscitation. Appropriate architectural and administrative measures can lessen these difficulties. The long, narrow magnet bore makes it difficult to observe the patient. Locating the operating console near the axis of the magnet provides a better, although still limited, view of the patient being scanned. Fringe magnetic fields may require location of the console relatively distant from the magnet. Magnetic shielding of the video display unit in the console can allow placement closer to the magnet. The window between the magnet room and control or console room usually requires RF shielding, which is often two layers of copper screen or perforated sheet. This shielding reduces patient visibility by light attenuation and by the distracting effect of Moire patterns and reflections. These problems can be reduced by appropriate window selection and attention to lighting details. Charge-coupled device (CCD) television cameras can be operated in relatively high magnetic fields and can be quite helpful in patient monitoring. Medical personnel and/or family members can remain near the patient to monitor or reassure the patient. The magnetic field within the scanner can affect or limit the performance of patient monitoring and communication equipment. For example, the magneto-hydrodynamic effect from flowing blood distorts electrocardiograph signals. Various solutions are being developed for these problems, such as using the main magnetic field as the field for a speaker or piping in sound via airline style head phones or providing a pneumatic squeeze bulb as a call button for the patient. Interfacing these devices with external systems is sometimes difficult. The operation of patient support equipment such as respirators, and infusion pumps can be affected near some types of magnets and other equipment such as stretchers, oxygen tanks and intravenous (IV) poles may be subjected to strong attractive forces near the magnet bore. These problems and difficulties with monitoring will make some patients inappropriate candidates for MR imaging until better solutions are found. MR lmager Site Planning Page 17 Cardiopulmonary resuscitation (CPR) is severely limited adjacent to some magnets because of the possible malfunction of CPR equipment in high fringe fields and the danger of ferromagnetic objects brought by the resuscitation team being attracted toward the magnet. The screening of arriving personnel for ferromagnetic objects is, of course, impossible. The usual solution is to remove the patient, by means of a non-ferromagnetic stretcher stationed in the scan room, to an area where CPR can be carried out. This area might be equipped with an emergency cart, monitors, oxygen and suction. Coordination of this phase of the design with the hospital’s CPR committee may be helpful. Means of preventing other personnel, who have responded to the emergency, from wandering into the magnet room during the activity surrounding CPR, should be considered. Useful means include distance, doors, warning signs and administrative procedures, such as training of the CPR team or assigning a member of the MR Imaging staff to close the magnet room door. Such situations necessitate a means of emergency shut down of the magnet. Claustrophobia and other forms of anxiety may interfere with imaging as well as patient comfort. Helpful solutions include good patient preparation, communication during scanning, someone remaining with the patient during scanning, disguising the intimidating appearance of the magnet, hiding the computer room from patient view, use of warm architectural finishes, keeping the magnet room size undramatic, disguising the vault-like appearance of the RF-shielded door, and making safety procedures and warning signs as nonthreatening as possible, consistent with adequate protection. The warm appearance of carpet must be weighed against the durability and maintenance advantages of traditional floors. Controlled access to the MR lmager suite is necessary because of possible harm to people with ferromagnetic medical implants and harm to people and equipment from unrestrained ferromagnetic objects in the vicinity of the magnet. A single entrance to the suite is helpful in this regard. Provision must be made for housekeeping personnel with floor polishers, for security personnel with keys, radios and guns, and for firemen with air tanks and axes. Non-ferromagnetic mops and buckets in a special closet or a built-in vacuum cleaner with plastic implements can be supplemented by direct supervision and/or training. If a special lock on the magnet door, which is not part of the hospital master key system, is used, emergency access to the key will be required.
