Gastric Bypass Surgery And Treatment Of People With Type 2 Diabetes

Gastric Bypass Surgery And Treatment Of People With Type 2 Diabetes.
Though it began as a therapy for something else entirely, gastric circumvent surgery - which involves shrinking the longing as a way to lose weight - has proven to be the news and possibly most effective treatment for some people with type 2 diabetes. Just days after the surgery, even before they creation to lose weight, people with type 2 diabetes see sudden upswing in their blood sugar levels. Many are able to quickly come off their diabetes medications.

So "This is not a silver bullet," said Dr Vadim Sherman, medical leader of bariatric and metabolic surgery at the Methodist Hospital in Houston. "The or heraldry argent bullet is lifestyle changes, but gastric bypass is a mechanism that can help you get there". The surgery has risks, it isn't an appropriate treatment for everyone with archetype 2 diabetes and achieving the desired result still entails lifestyle changes.

And "The surgery is an competent option for obese people with type 2 diabetes, but it's a very big step," said Dr Michael Williams, an endocrinologist associated with the Swedish Medical Center in Seattle. "It allows them to be beaten a huge amount of weight and mimics what happens when people make lifestyle changes. But, the increase in glucose control is far more than we'd expect just from the weight loss".

Almost 26 million Americans have kidney 2 diabetes, according to the American Diabetes Association. Being overweight is a significant gamble factor for type 2 diabetes, but not everyone who has the disease is overweight. Type 2 occurs when the body stops using the hormone insulin effectively. Insulin helps glucose enter the body's cells to present energy.

Lifestyle changes, such as losing 5 to 10 percent of body avoirdupois and exercising regularly, are often the pre-eminent treatments suggested. Many people find it difficult to make permanent lifestyle changes on their own, however. Oral medications are also available, but these often prove inadequate to control type 2 diabetes adequately. Injected insulin can also be given as a treatment.

Surgeons start noted that gastric bypass surgeries had an drift on blood sugar control more than 50 years ago, according to a review article in a late-model issue of The Lancet. At that time, though, weight-loss surgeries were significantly riskier for the patient. But as techniques in bariatric surgery improved and the surgical intricacy rates came down, experts began to re-examine the objective the surgery was having on type 2 diabetes. In 2003, a consider in the Annals of Surgery reported that 83 percent of people with type 2 diabetes who underwent the weight-loss surgery known as Roux-en-Y gastric detour saw a resolution of their diabetes after surgery.

Patients With Cancer Choose Surgery

Patients With Cancer Choose Surgery.
People with talk cancer who endure surgery before receiving radiation treatment fare better than those who start treatment with chemotherapy, according to a small reborn study. Many patients may be hesitant to begin their treatment with an invasive procedure, University of Michigan researchers noted. But advanced surgical techniques can pick up patients' chances for survival, the authors illustrious in a university news release. The study was published online Dec 26, 2013 in JAMA Otolaryngology Head and Neck Surgery.

Nearly 14000 Americans will be diagnosed with voice cancer this year and 2,070 will Euphemistic depart from the disease, according to the American Cancer Society. "To a minor person with tongue cancer, chemotherapy may sound like a better option than surgery with extensive reconstruction," inquiry author Dr Douglas Chepeha, a professor of otolaryngology-head and neck surgery at the University of Michigan Medical School, said in the despatch release. "But patients with oral pit cancer can't tolerate induction chemotherapy as well as they can handle surgery with follow-up radiation".

And "Our techniques of reconstruction are advanced and propose patients better survival and functional outcomes". The retreat involved 19 people with advanced oral cavity mouth cancer. All of the participants were given an first dose of chemotherapy (called "induction" chemotherapy). Patients whose cancer was reduced in square footage by 50 percent received more chemotherapy as well as radiation therapy.

The Use Of Steroids For The Treatment Of Spinal Stenosis

The Use Of Steroids For The Treatment Of Spinal Stenosis.
Older adults who get steroid injections for degeneration in their put down spinal column may fare worse than woman in the street who skip the treatment, a small study suggests. The research, published recently in the chronicle Spine, followed 276 older adults with spinal stenosis in the lower back. In spinal stenosis, the raise spaces in the spinal column gradually narrow, which can put pressure on nerves. The important symptoms are pain or cramping in the legs or buttocks, especially when you walk or stand for a crave period.

The treatments range from "conservative" options like anti-inflammatory painkillers and physical psychotherapy to surgery. People often try steroid injections before resorting to surgery. Steroids calm inflammation, and injecting them into the room around constricted nerves may ease pain - at least temporarily. In the unexplored study, researchers found that patients who got steroid injections did see some pain relief over four years.

But they did not diet as well as patients who went with other conservative treatments or with surgery right away. And if steroid patients ultimately opted for surgery, they did not improve as much as surgery patients who'd skipped the steroids.

It's not shiny why, said lead researcher Dr Kris Radcliff, a spine surgeon with the Rothman Institute at Thomas Jefferson University, in Philadelphia. "I deem we need to face at the results with some caution". Some of the study patients were randomly assigned to get steroid injections, but others were not - they opted for the treatment. So it's accomplishable that there's something else about those patients that explains their worse outcomes.

On the other workman steroid injections themselves might hamper healing in the long run. One likelihood is that injecting the materials into an already cramped space in the spine might make the situation worse, once the endorse pain-relieving effects of the steroids wear off. "But that's just our speculation".

A pain brass specialist not involved in the work said it's impossible to pin the blame on epidural steroids based on this study. For one, it wasn't a randomized clinical trial, where all patients were assigned to have steroid injections or not have them, said Dr Steven Cohen, a professor at Johns Hopkins School of Medicine, in Baltimore. The patients who opted for epidural steroids "may have had more difficult-to-treat pain, or a worse pathology".

US Doctors Confirm The Correct Solution To The Problem Of Epilepsy

US Doctors Confirm The Correct Solution To The Problem Of Epilepsy.
The behemoth the greater part of epilepsy patients who have brain surgery to doctor the seizure disorder find it improves their mood and their ability to work and drive, a new weigh reveals. Meanwhile, a second study also indicates the procedure is safe and effective for patients over 60. "They're both reassuring findings," said Bruce Hermann, chief of the Charles Matthews Neuropsychology Lab at the University of Wisconsin School of Medicine and Public Health. "Epilepsy is a enigmatic civil disorder to have and live with, coming with a high rate of depression and affecting the ability to drive and work.

And "We always hoped surgery would have dogmatic effects on patients' life situations, and this research does show that, and shows that the outcomes persist," added Hermann, who was not implicated with the research Dec 2013. Both studies are scheduled to be presented Sunday at the American Epilepsy Society annual tryst in Washington, DC Research presented at ordered conferences is considered preliminary until published in a peer-reviewed medical journal.

Affecting about 2,2 million Americans and 65 million grass roots globally, epilepsy is a seizing disorder triggered by abnormal nerve cell signaling in the brain, according to the Epilepsy Foundation. More than 1 million Americans with epilepsy go down from treatment-resistant seizures that can hamper their ability to drive, run and learn. Epilepsy is the third most common neurological disorder, after Alzheimer's disease and stroke.

The Number Of Cataract Disease Increases As The Extension Of Human Life

The Number Of Cataract Disease Increases As The Extension Of Human Life.
Americans are living longer than ever before and most ladies and gentlemen who conclude into their 70s and beyond will arise cataracts at some point. That's why it's important to know the risks and symptoms of cataract, what to do to check onset, and how to decide when it's time for surgery, experts at the American Academy of Ophthalmology (AAO) explained in a dope release. People should get a baseline eye screening exam at age 40, when ancient signs of disease and vision change may begin to occur, according to the AAO. During the visit, the ophthalmologist will clarify how often to schedule follow-up exams.

People of any age who have symptoms or are at risk for eye disease should originate an appointment with an ophthalmologist to establish a care and follow-up plan. Risk factors for cataract encompass family history, having diabetes, smoking, extensive exposure to sunlight, serious recognition injury or inflammation, and prolonged use of steroids, especially combined use of oral and inhaled steroids.

Scientists Have Found A New Way To Lose Weight

Scientists Have Found A New Way To Lose Weight.
A uncharted commentary finds that weight-loss surgery helps very obese patients smidgen pounds and improve their overall health, even if there is some risk for complications. "We've gotten good at doing this," said Dr Mitchell Roslin, main of weight-loss surgery at Lenox Hill Hospital in New York City. "Bariatric surgery has become one of the safest intra-abdominal prime procedures. The quiz is why we don't start facing the facts who was not involved in the new review. If the data were this OK with any other condition, the standard of care for morbid obesity would be surgery. He said he thinks a unfairly against obesity tinges the way people look at weight-loss surgery.

And "People don't objective obesity as a disease, and blame the victim. We have this ridiculous notion that the next diet is going to be serviceable - although there has never been an effective diet for people who are severely obese". Morbid obesity is a chronic fettle that is practically irreversible and needs to be treated aggressively. The only treatment that's effective is surgery. Review creator Su-Hsin Chang is an instructor in the division of public health services at the Washington University School of Medicine, in St Louis.

So "Weight-loss surgery provides generous crap on weight loss and improves obesity-related conditions in the majority of bariatric patients, although risks of complication, reoperation and extirpation exist. Death rates are, in general, very low. The dimensions of weight loss and risks are different across different procedures. These should be well communicated when the surgical recourse is offered to obese patients and should be well considered when making decisions".

The report was published online Dec 18, 2013 in the periodical JAMA Surgery. For the study, Chang's yoke analyzed more than 150 studies related to weight-loss surgery. More than 162000 patients, with an regular body-mass index (BMI) of nearly 46, were included. BMI is a measure of body fat based on summit and weight, and a BMI of more than 40 is considered very severely obese.

Both Medications And Deep Brain Stimulation Surgery May Make Better Life With Parkinson'S Disease

Both Medications And Deep Brain Stimulation Surgery May Make Better Life With Parkinson'S Disease.
Parkinson's disability patients do better if they be subjected to heavily brain stimulation surgery in addition to treatment with medication, new research suggests. One year after having the procedure, patients who underwent the surgery reported better blue blood of life and improved facility to get around and engage in routine daily activities compared to those who were treated with medication alone, according to the weigh published in the April 29 online edition of The Lancet Neurology.

The study authors notorious that while the surgery can provide significant benefits for patients, there also is a risk of serious complications. In profoundly brain stimulation, electrical impulses are sent into the brain to adjust areas that control movement, according to credentials information in a news release about the research. In the new study, Dr Adrian Williams of Queen Elizabeth Hospital in Birmingham and colleagues in the United Kingdom randomly assigned 366 Parkinson's ailment patients to either sustain drug treatment or drug treatment extra surgery.

One year later, the patients took surveys about how well they were doing. "Surgery is likely to linger an important treatment option for patients with Parkinson's disease, especially if the way in which deep brain stimulation exerts its medical benefits is better understood, if its use can be optimized by better electrode placement and settings, and if patients who would have the greatest profit can be better identified," the authors concluded.

Deep brain stimulation (DBS) is a surgical procedure in use to treat a variety of disabling neurological symptoms—most commonly the debilitating symptoms of Parkinson's blight (PD), such as tremor, rigidity, stiffness, slowed movement, and walking problems. The operation is also used to treat essential tremor, a common neurological movement disorder.

Statins May Reduce The Risk Of Prostate Cancer

Statins May Reduce The Risk Of Prostate Cancer.
Cholesterol-lowering statins significantly mark down prostate tumor inflammation, which may hand lower the risk of disease progression, redesigned study findings suggest. Duke University Medical Center researchers found that the use of statins before prostate cancer surgery was associated with a 69 percent reduced good chance of inflammation preferential prostate tumors.

For the study, the researchers examined tissue samples of prostate tumors from 236 men undergoing prostate cancer surgery. The patients included 37 who took statins during the year erstwhile to their surgery.

Overall, 82 percent of the men had riotous cells in their prostate tumors and about one-third had signal tumor inflammation. After they accounted for factors such as age, mill-race and body-mass index (a measurement that is based on weight and height), the Duke team concluded that statin use was associated with reduced swelling within tumors.

Laparoscopic Surgery Of The Colon Reduces The Risk Of Venous Thrombosis

Laparoscopic Surgery Of The Colon Reduces The Risk Of Venous Thrombosis.
Minimally invasive colon surgery reduces the imperil of blood clots in the intense veins compared with ancestral surgery, University of California, Irvine, researchers report. Deep tendency blood clots, called venous thromboembolism (VTE), occur in about a board of patients who have colorectal surgery, the researchers said. The benefits of less invasive laparoscopic surgery also subsume faster recovery time and a smaller scar, but these advantages may not be enough to bring about a widespread change from traditional surgery.

And "From the cancer perspective, this does not appear to be a game changer," said Dr Durado Brooks, big cheese of colorectal cancer at the American Cancer Society. Brooks said that amid cancer patients in the study, no significant difference in the risk of VTE was found between the two procedures.

So "In addition, cancer had been viewed as a contraindication for laparoscopic surgery. There needs to be a more focused on looking exclusively at the cancer citizenry before anyone would promote laparoscopic surgery as the way to go for cancer patients". The record was published in the June issue of the Archives of Surgery.

Orthopedists Recommend Replace Diseased Joints

Orthopedists Recommend Replace Diseased Joints.
Millions of Americans encounter commonplace with degenerative, painful and crippling knee or hip arthritis, or similar chronic conditions that can round the simplest task into an ordeal. Fortunately, for those immobilized by their disease, hope exists in the form of knee or informed replacement, long considered the best shot at improving quality of life. The hitch: a prohibitory price tag. "Unfortunately, I've lost three jobs due to downsizing since 2006," said 51-year prehistoric Susan Murray, a Freehold, NJ, resident.

Murray has been combating a connective network disease that has progressively ravaged her knees. "And about six months ago I wasted my health coverage. I just could no longer afford to pay my bills and also keep up with my insurance payments". So in the face an illness that leaves her cane-dependent and in constant pain, the single mother of three had no situation to pay the $50000 to $60000 average out-of-pocket cost for both surgical and postsurgical care.

Enter Operation Walk USA (OWUSA). According to OWUSA, the program was launched in 2011 as an annual nationwide toil to supply joint replacement surgery at zero cost for uninsured men and women for whom such expenses are out of reach. The pep is an outgrowth of the internationally focused Operation Walk, which since 1996 has provided allowed surgery to more than 6000 patients around the world, according to an OWUSA news release.

OWUSA initially solicited doctors and hospitals to volunteer their services one age each December to surgically break in in the lives of American patients in need. This year the effort has expanded greatly, as 120 orthopedic surgeons joined forces with 70 hospitals in 32 states to make connection surgery to 230 patients spanning the course of a full week in December. "With millions of family affected, we're trying to reach out to those who are underserved," said Dr Giles Scuderi, an OWUSA organizer and orthopedic surgeon.

The knee arthroplasty adept currently serves as blemish president of the orthopedic service line at North Shore LIJ Health System, an OWUSA partaker based in the greater New York City region. "Now by underserved we're remarkably talking about 'population USA'. That is, everyday people in our communities, our colleagues, our friends, rank and file who lost their insurance for whatever reason. Maybe they had a job that they could no longer put on because of their illness, and so lost insurance, and couldn't get it again because of a pre-existing condition.

Still Occasionally After Surgery In Children Remain Inside The Surgical Instruments

Still Occasionally After Surgery In Children Remain Inside The Surgical Instruments.
It on rare occasions happens, but that's toy comfort for those involved: Sometimes surgical instruments and sponges are progressive inside children undergoing surgery, according to researchers from Johns Hopkins University. Children affliction from such mishaps were not more likely to die, but the errors result in convalescent home stays that are more than twice as long and cost more than double that of the average stay, the researchers found. And that's not even counting the mental toll on families.

And "Certainly, from a family's perspective, one event for example this is too many," said lead researcher Dr Fizan Abdullah, an assistant professor of surgery at Johns Hopkins. "Regardless of the data, we as a form care system have to be sensitive to these families. The extraordinary thing is that when you look at the numbers, it translates to one event in every 5000 surgeries. When there are hundreds of thousands of surgeries being performed on children across the US every year, that's a lot of patients".

The gunfire is published in the November 2010 matter of the Archives of Surgery. For the study, Abdullah's span collected data on 1,9 million children under 18 who were hospitalized from 1988 to 2005. Of all these children, 413 had an contrivance or sponge left inside them after surgery, the researchers found.

The mistakes occurred most often when the surgery interested opening the abdominal cavity, such as during a gynecologic procedure. Errors were less appropriate to occur during ear, nose, throat, heart and chest, orthopedic and spine surgeries, Abdullah's organize notes.

Obesity Can Be A Barrier To Pregnancy

Obesity Can Be A Barrier To Pregnancy.
Women should tarry at least one year after having weight-loss surgery before they analyse to get pregnant, researchers say. The chubbiness rate among women of child-bearing age is expected to rise from about 24 percent in 2005 to about 28 percent in 2015, and the enumerate of women having weight-loss surgery is increasing, the researchers noted. In a review, published Jan 11, 2013 in The Obstetrician & Gynaecologist, investigators looked at c whilom studies to assess the safety, limitations and advantages of weight-loss ("bariatric") surgery, and guidance of weight-loss surgery patients before, during and after pregnancy.

Obesity increases the imperil of pregnancy complications, but weight-loss surgery reduces the chance in extremely obese women, the criticize authors said. One study found that 79 percent of women who had weight-loss surgery proficient no complications during their pregnancy. However, the review also found that complications during pregnancy can occur in women who have had weight-loss surgery.

Treatment Options For Knee

Treatment Options For Knee.
Improvements in knee despair following a common orthopedic form appear to be largely due to the placebo effect, a new Finnish study suggests. The research, which was published Dec 26, 2013 in the New England Journal of Medicine, has heavy implications for the 700000 patients who have arthroscopic surgery each year in the United States to fixing a torn meniscus. A meniscus is a C-shaped filling of cartilage that cushions the knee joint.

For a meniscal repair, orthopedic surgeons use a camera and trifling instruments inserted through small incisions around the knee to shear damaged tissue away. The idea is that clearing sharp and unstable debris out of the communal should relieve pain. But mounting evidence suggests that, for many patients, the procedure just doesn't pan out as intended. "There have been several trials now, including this one, where surgeons have examined whether meniscal run surgery accomplishes anything, basically, and the answer through all those studies is no, it doesn't," said Dr David Felson, a professor of medication and public health at Boston University.

He was not convoluted in the new research. For the new study, doctors recruited patients between the ages of 35 and 65 who'd had a meniscal dash and knee pain for at least three months to have an arthroscopic wont to examine the knee joint. If a patient didn't also have arthritis, and the surgeon viewing the knee ascertained they were eligible for the study, he opened an envelope in the operating room with further instructions.

At that point, 70 patients had some of their damaged meniscus removed, while 76 other patients had nothing further done. But surgeons did all they could to place the sham procedure seem like the real thing. They asked for the same instruments, they moved and pressed on the knee as they otherwise would, and they occupied mechanical instruments with the blades removed to simulate the sights and sounds of a meniscal repair. They even timed the procedures to total sure one wasn't shorter than the other.

The Depression Is Associated With Heart Troubles

The Depression Is Associated With Heart Troubles.
Depression is rather stock in patients who undergo heart bypass surgery, and a new study finds that short-term use of antidepressants may support patients' recovery May 2013. "Depression among patients requiring or having undergone sidestep surgery is high and can significantly impact postoperative recovery," said one crackerjack not connected to the study, Dr Bryan Bruno, acting chairman of the department of psychiatry at Lenox Hill Hospital in New York City. In this study, a duo of French researchers looked at 182 patients who started taking a discerning serotonin reuptake inhibitor (SSRI) antidepressant two to three weeks before undergoing coronary artery go graft surgery and continued taking it for six months after the procedure.

SSRIs number widely used antidepressants such as Celexa, Lexapro, Prozac, Paxil and Zoloft. In this study, patients took one 10 milligram tombstone of Lexapro (escitalopram) daily. The reflect on was funded by Lexapro's maker, H Lundbeck A/S. The outcomes of patients prescribed Lexapro were compared to 179 patients who took an dormant placebo as an alternative of the antidepressant.

During the six months after the surgery, the patients who took the antidepressant reported less dejection and better quality of life than those who took the placebo, the researchers reported. In addition, taking antidepressants did not multiplication the risk of complications or death in the year after surgery, according to the study, which appears in the May culmination of the Annals of Thoracic Surgery.

Anesthesia Affects The Heart

Anesthesia Affects The Heart.
More unsettle about the safety of a common anesthetic has been raised in a unripe study. Patients who received the anesthesia drug etomidate during surgery might be at increased chance for cardiovascular problems or death, according to the study, which was published in the December issue of the journal Anesthesia and Analgesia. An accompanying column in the journal said the findings add to growing concerns about the use of the drug. The survey compared about 2100 patients who received etomidate and about 5200 patients who received another intravenous anesthetic called propofol.

All of the patients in the deliberate over underwent surgery that didn't number among the heart. Compared to those who received propofol, patients who received etomidate had a significantly higher gamble of death within 30 days after surgery, according to a journal news release. The risk was 6,5 percent in the etomidate organize and 2,5 percent in the propofol group, said study chief Dr Ryu Komatsu, of the Cleveland Clinic in Ohio.

Chemotherapy Is One Of The Main Ways To Treat Cancer

Chemotherapy Is One Of The Main Ways To Treat Cancer.
Women fighting an forward appearance of breast cancer may benefit from adding indisputable drugs to their chemotherapy regimen, and taking them prior to surgery, new research finds. This pre-surgical stimulant therapy boosts the likelihood that no cancer cells will be found in breast tissue removed during either mastectomy or lumpectomy, according to two untrained studies. The approach, called "neoadjuvant" chemotherapy, is being given to an increasing include of women with what's known as triple-negative breast cancer.

Currently, the approach results in no identifiable cancer cells at mastectomy or lumpectomy in about-one third of patients, experts estimate. In such cases, the imperil of a tumor recurrence becomes lower. "Chemotherapy before surgery does piece in triple-negative chest cancer. What we want to do is make it work better," said study researcher Dr Hope Rugo.

Rugo is kingpin of breast oncology and clinical trials education at the Helen Diller Family Comprehensive Cancer Center at the University of California, San Francisco. Triple-negative cancers have cells that deficit receptors for the hormones estrogen and progesterone. In addition, they don't have an remaining of the protein known as HER2 on the cubicle surfaces.

So, treatments that work on the receptors and drugs that object HER2 don't work in these cancers. In two new studies, researchers got better results by adding drugs to the pattern chemo regimen prior to surgery. However, both studies are condition 2 trials, so more research is needed. Both studies are due to be presented Friday at the annual San Antonio Breast Cancer Symposium.

MRI Is More Effective Than X-Rays For Diagnose Hip Fractures In The Emergency Room

MRI Is More Effective Than X-Rays For Diagnose Hip Fractures In The Emergency Room.
X-rays often fade to locate hip and pelvic fractures, a creative US study says. Duke University Medical Center researchers analyzed gen on 92 emergency department patients who were given an X-ray and then an MRI to evaluate onto and pelvic pain.

So "Thirteen patients with normal X-ray findings were found to collectively have 23 fractures at MRI," the study's persuade author, Dr Charles Spritzer, said in a news let out from the American College of Radiology American Roentgen Ray Society. In addition, the examination found that, "in 11 patients, MRI showed no fracture after X-rays had suggested the presence of a fracture. In another 15 patients who had odd X-ray findings, MRI depicted 12 additional pelvic fractures not identified on X-rays".

An on target diagnosis in an emergency department can "speed patients to surgical management, if needed, and humble the rate of hospital admissions among patients who do not have fractures. This separation is important in terms of health-care utilization, overall patient cost and patient inconvenience".

To bring off this, MRI has advantages, the researchers said in their report, in the April issue of the American Journal of Roentgenology. "Use of MRI in patients with a large clinical suspicion of traumatic damage but unimpressive X-rays has a substantial advantage in the detection of pelvic and hip fractures, helping to channel patients to appropriate medical and surgical therapy," Spritzer concluded.

A hip fracture is a relax in the bones of your hip (near the top of your leg). It can happen at any age, although it is more common is people 65 and older. As you get older, the middle of your bones becomes porous from a loss of calcium. This is called losing bone mass. Over time, this weakens the bones and makes them more in all probability to break. Hip fractures are more low-grade in women, because they have less bone mass to start with and lose bone mass more quickly than men.

Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an darned non-poisonous and successful procedure, can be made more precise by combining a laser and three-dimensional imaging, a untrodden study suggests. Researchers found that a femtosecond laser, used for many years in LASIK surgery, can edit into delicate eye tissue more cleanly and accurately than manual cataract surgery, which is performed more than 1,5 million times each year in the United States. In the in touch procedure, which has a 98 percent good rate, surgeons use a micro-blade to cut a circle around the cornea before extracting the cataract with an ultrasound machine.

The laser system uses optical coherence technology to customize each patient's orb measurements before slicing through the lens capsule and cataract, though ultrasound is still used to remove the cataract itself. "It takes some artistry and energy to break the lens with the ultrasound," explained induce researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University. "The laser helps to bowl along this up and make it safer".

After practicing the laser procedure on pig eyes and donated benignant eyes, Palanker and his colleagues did further experiments to confirm that the high-powered, rapid-pulse laser would not cause retinal damage. Actual surgeries later performed on 50 patients between the ages of 55 and 80 showed that the laser adulterate circles in lens capsules 12 times more demanding than those achieved by the customary method. No adverse effects were reported.

The study, reported in the Nov 17, 2010 issuance of Science Translational Medicine, was funded by OpticaMedica Corp of Santa Clara, Calif, in which Palanker has an tolerance stake. The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several confidential companies, is expected to be released worldwide in 2011.

Features Of Surgery For Cancer

Features Of Surgery For Cancer.
After chemotherapy, surgery and dispersal to to the original tumor might not benefit women with advanced breast cancer, a new work shows in Dec 2013. A minority of women with breast cancer discover they have the condition in its later stages, after it has spread to other parts of the body. These patients typically are started on chemotherapy to balm shrink the cancerous growths and slow the disease's progress. Beyond that, doctors have hanker wondered whether it's also a good idea to treat the original breast tumor with surgery or diffusion even though the cancer has taken root in other organs.

And "Our trial did show there's no benefit of doing surgery," said inspect author Dr Rajendra Badwe, head of the surgical breast constituent at Tata Memorial Hospital in Mumbai, India. It didn't seem to matter if patients were prepubescent or old, if their cancer was hormone receptor positive or negative, or if they had a few sites of spreading cancer or a lot. Surgery didn't elongate their lives. The study was scheduled for presentation this week at the annual San Antonio Breast Cancer Symposium, in Texas.

The results aren't shocking, since experiments in animals performed more than 30 years ago suggested that scornful out the fundamental tumor only egged on cancer at the auxiliary sites. But studies in humans have suggested that removing the original cancer in the heart of hearts may increase survival. Those studies aren't thought to be definitive, however, because they looked back only at what happened after women already underwent treatment. One polished not involved in the new study also questioned the group of patients in the previous research.

So "There's a lot of bias with that because you tend to operate on patients you think might do well to begin with," said Dr Stephanie Bernik, first of surgical oncology at Lenox Hill Hospital in New York City. "We assuredly need more evidence to guide us". To get that evidence, researchers randomly assigned 350 women who responded to their initial chemotherapy to one of two courses of treatment. The win group had surgery followed by radiation to remove the model breast tumor and lymph nodes under the arms.

The Level Of Occurrence Of Serious Complications After Weight-Loss Surgery

The Level Of Occurrence Of Serious Complications After Weight-Loss Surgery.
Weight-loss surgery, also known as bariatric surgery, in the assert of Michigan has a less indecent rate of serious complications, a new study suggests. The lowest rates of complications are associated with surgeons and hospitals that do the highest or slue of bariatric surgeries, according to the report published in the July 28 son of the Journal of the American Medical Association. Rates of bariatric surgery have risen over the history decade and it is now the second most common abdominal operation in the country.

Despite declining death rates for the procedures, some groups persist concerned about the risks of the surgery and uneven levels of quality amongst hospitals, researchers at the University of Michigan pointed out in a news release from the journal's publisher. In the creative study, Nancy Birkmeyer of the University of Michigan, Ann Arbor, and colleagues analyzed evidence from 15275 patients who underwent one of three common bariatric procedures between 2006 and 2009. The operations were performed by 62 surgeons at 25 hospitals in Michigan.

Overall, 7,3 percent of patients expert one or more complications during surgery, most of which were pain problems and other minor complications. Serious complications were most garden-variety after gastric bypass (3,6 percent), sleeve gastrectomy (2,2 percent), and laparoscopic adjustable gastric corps (0,9 percent) procedures, the investigators found. Rates of precarious complications at hospitals varied from 1,6 percent to 3,5 percent.
