Whether drawing blood specimens or starting IVs, venipuncture is the most commonly performed invasive medical procedure. It is also one that frequently requires additional time and multiple attempts to be successful. In fact, establishing IV access in difficult patients can take up to 10 minutes. Of all invasive medical procedures, venipuncture is the most common and these venipuncture attempts can fail. As a result: Blood tests that facilitate diagnosis and patient management may be delayed; Intravenous therapy may not begin promptly; Physician intervention to access a difficult vein can erode productivity; Patients may endure unnecessary needlesticks and additional discomfort; Stress may increase for both patients and staff. But by using vein illumination with AccuVein’s breakthrough device, many veins that might be otherwise undetectable without a vein locator, can be located and mapped on the patient’s skin. How Does It Work? Hemoglobin in the blood absorbs infrared light. When the...

A 20-year-old Chilean woman, Yaritza Oliva, cries tears of blood, and doctors aren't quite sure why. Since June, Oliva has been crying blood tears several times a day, a pain she called "indescribable."  While doctors have not officially diagnosed the 20-year-old, it's likely that she is one of several people to develop haemolacria, a rare condition marked by bleeding from the eyes. A simple eye infection and conjunctivitis were ruled out since Oliva continued to shed tears of blood several times per day. Watch The Video What is Haemolacria ??? Haemolacria is a physical condition that causes a person to produce tears that are partially composed of blood. It can manifest as tears that are anything from merely red-tinged to appearing to be entirely made of blood. Haemolacria is a symptom of a number of diseases,and may also be indicative of a tumor in the lacrimal apparatus. It is most often provoked by local factors such as bacterial conjunctivitis, environmental damag...

The British man, identified only as Graham, woke up nine years ago utterly convinced that he was no longer alive even though he was still breathing. Doctors diagnosed him with Cotard’s Syndrome, which is also known as ‘Walking Corpse Syndrome’ because it makes people think they have turned into zombies. Graham did not believe them, however, and insisted that his brain was dead. The unusual condition emerged after Graham, who suffered from severe depression, tried to commit suicide by taking an electrical appliance with him into the bath. Eight months later he told doctors that his brain had died or was, at best, missing. He lost interest in smoking, stopped speaking and refused to eat as there was "no point because I was dead" He was in the grip of Cotard's syndrome. People with this rare condition believe that they, or parts of their body, no longer exist. For Graham, it was his brain that was dead, and he believed that he had killed it. In a new study  in  Cortex  ...

Rahul has been virtually in flames four times since he was born two-and-a-half months ago. Doctors suspected  it's due to a rare condition called spontaneous human combustion (SHC). Afflicted with the disorder, seen only in 200 people across the world in the past 300 years, the child undergone treatment at  Kilpauk  Medical College ( KMC ) Hospital, Chennai, India. Rahul was nine days old when he first "caught fire" in the presence of his mother Rajeshwari who watched in disbelief as there was no source of fire in the vicinity. She took him to the Villupuram Medical College from where the baby was discharged three days later. After coming home, he suffered burns again. "Doctors say he is a healthy child and his organs are fine. The last time he caught fire was a fortnight ago, and this time it was head to toe," said Rajeshwari J. Jagan Mohan, head of plastic surgery, who examined the baby, said there was very remote possibility of self-ignition. “The injuries ha...

Ali Hussain Khan from Bihar, India, is only 14 years old, but the condition, called progeria, has given him the body of a 110-year-old. His parents, who are first cousins, have eight children. Four born with progeria died between ages 12 and 24. Another child, who died shortly after birth, is also thought to have had the disease. Two of their daughters do not have progeria. There are only about 80 cases of progeria known in the world. According to the Progeria Research Foundation, a nonprofit that seeks to cure the condition and its aging-related disorders , the children with progeria "are born looking healthy... [but] begin to display many characteristics of accelerated aging at around 18-24 months of age." Watch The Video What is Progeria ? Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare hereditary disease that affects the skin, musculoskeletal system, and vasculature. HGPS is characterized by signs of premature aging. The term progeria is derived from the ...

Dr. Christopher Kaeding, an orthopedic surgeon at The Ohio State University Wexner Medical Center is shown wearing Google Glass while performing surgery. Dr. Christopher Kaeding, a surgeon at The Ohio State University Wexner Medical Center, is the first in the U.S  to consult with a distant colleague using live, point-of-view video from the operating room via Google Glass, a head-mounted computer and camera device. Google Glass has a frame similar to traditional glasses, but instead of lenses, there is a small glass block that sits above the right eye.  On that glass is a computer screen that, with a simple voice command, allows users to pull up information as they would on any other computer.  Attached to the front of the device is a camera that offers a point-of-view image and the ability to take both photos and videos while the device is worn. Dr. Christopher Kaeding, a surgeon at the Ohio State University Wexner Medical Center, was performing a surgery on a 47-year-ol...

Researchers in Calgary, Alberta, have tested a new robot programmed to distract children during flu shots.  The study, published  in medical journal Vaccine , found the "MEDi" robot reduced pain and distress in children getting the flu vaccine at Alberta Children's Hospital. The robot, named MEDi™ (which stands for Medicine and Engineering Designing Intelligence), was purchased by the University of Calgary’s Shulich School of Engineering from Aldebaran Robotics — a French startup company headquartered in Paris — and can mimic many things a child can do. Reducing children's pain and distress towards flu vaccinations: A novel and effective application of humanoid robotics Objective Millions of children in North America receive an annual flu vaccination, many of whom are at risk of experiencing severe distress. Millions of children also use technologically advanced devices such as computers and cell phones. Based on this familiarity, we introduced another sophisticated d...

An experimental surgical "knife" can accurately identify cancerous tissue as a surgeon cuts through it, creating the potential for shorter cancer surgeries that remove all traces of tumor, according to a study co-written by the device's developers. The "iKnife" uses electricity to cauterize surgical incisions as they are made, and then samples the resulting smoke to determine whether the tissue being cut is healthy or cancerous. The iKnife accurately identified cancerous and healthy tissue 97 percent of the time in recent human trials, according to the study published July 17 in the journal  Science Translational Medicine Intraoperative Tissue Identification Using Rapid Evaporative Ionization Mass Spectrometry Rapid evaporative ionization mass spectrometry (REIMS) is an emerging technique that allows near–real-time characterization of human tissue in vivo by analysis of the aerosol (“smoke”) released during electrosurgical dissection. The coupling of REIMS techn...

Source: Discovery News When physicians run out of treatment options, they look to a nascent field known as bioengineering for solutions to their patients' ailments. Specialized scientists apply engineering principles to biological systems, opening up the possibility of creating new human tissue, organs, blood and even corneas such as the one shown here. Waiting lists for organ transplants continue to be lengthy so the race to save lives with bioengineered body parts is on. Here’s a look at some of the most notable achievements in recent years Skin Producing small amounts of artificial skin to graft onto patients and use for toxicity testing has been possible for years. Human skin cells are cultivated in the lab and then embedded in a collagen scaffold. In 2011, the Fraunhofer Institute for Interfacial Engineering and Biotechnology introduced a system that can rapidly manufacture two-layer artificial skin models. Their Tissue Factory has the capacity to make 5,000 skin sheets in a m...

Theese are images from Germany of a liver surgery, one of the first surgeries of its kind in the country with the support of a tablet computer to access and visualize planning data. The tablet uses augmented reality, which allows the liver to be filmed with an iPad and overlaid during an operation with virtual 3D models reconstructed from the real organ.  Developed by Fraunhofer MEVIS in Bremen, this procedure helps locate critical structures such as tumors and vessels and is expected to improve the quality of transferring pre operational resection plans into actual surgery.  Professor Karl Oldhafer, chief physician of general and visceral surgery at Asklepios Hospital Hamburg-Barmbek, and his colleagues removed two tumours from a patient’s liver using an iPad in a three-hour-long surgery that took place last week, Reuters reported. “I couldn’t imagine how an iPad would be helpful during an operation to remove two tumors from a liver,” photographer Fabian Bimmer, who filmed th...
