Virtual Reality Is Changing the Way Doctors Perform Surgery

Learning through observation has been a cornerstone of surgical education in the United States for over a hundred years. This practice is being increasingly challenged recently by legal and ethical concerns for patient safety, 80-hour resident work week restrictions, and the cost of operating room (OR) time. The emerging field of surgical simulation and virtual training offers an opportunity to teach and practice neurosurgical procedures outside of the OR. There is enormous potential to address patient safety, risk management concerns, OR management, and work hour requirements with more efficient and effective training methods.[4] The current goal of simulator training is to help trainees ac

Dijital - Video Oyun Bağımlılığı Artık Bir Hastalık

Dünya sağlık örgütü (DSÖ) , aşırı oyun oynamayı (video ya da dijital oyunlar) akıl sağlığı hastalığı olarak adlandırdı. Evet yanlış anlamadınız, DSÖ, oyun bağımlılığını akıl sağlığı hastalığı olarak sınıflandırdı. Eğer bir insan gerçek hayatla ilişkisi yerine oyun oynamayı daha fazla önemsiyor ve durmaksızın oyun oynuyorsa bu hastalığa yakalandığı kabul ediliyor. Bu tür bir hastalığı olan hasta yılda en az bir kere doktora gitmeli. DSÖ tarafından oyun bağımlılığının doktorlar tarafından toplum sağlığını etkilemesi ve ciddi sonuçlarının olabileceği hakkında toplumun bilgilendirilmesi gerektiği ifade ediliyor. Çoğu insan video oyunlarını oynamanın bir zararının olmadığını düşünüyor. Ancak çoğu

This modified smartphone measures blood pressure directly from your finger

High blood pressure can lead to heart disease and stroke, but it often goes undetected and untreated. A new technology could change that by putting a simple blood pressure monitor in everyone’s pockets. Normally, blood pressure is measured using an inflatable cuff that presses down on an artery in the arm while a device records the effect on blood flow. Now, scientists have created a smartphone attachment that measures blood pressure directly from the finger, removing the need for any specialized equipment. The user places their finger on a pressure sensor and is guided by a chart displayed on the phone to gradually increase the applied force. Meanwhile, another sensor measures blood volume

Too Much Sitting May Shrink the Part of Your Brain Tied to Memory

It may be time to ditch the desk chair: A new study links sitting too much each day with memory problems in middle-age and older adults. Researchers from the University of California, Los Angeles (UCLA) found that long stretches of sedentary behavior — like spending all day in your desk chair — were linked to changes in a part of the adult brain that's critical for memory. Earlier research has linked sedentary behavior to an increased risk of heart disease, diabetes and premature death in middle-age and older adults. The new study, published yesterday (April 12) in the journal PLOS One, builds on this, focusing on inactivity's impacts on the brain, according to a statement from the researche

A 13-Year-Old Died After a Sinus Infection Traveled to His Brain. How Does That Happen?

A Michigan community is in mourning after the death of 13-year-old Marquel Brumley, and the circumstances behind the eight-grader’s death are certainly alarming: After being diagnosed at an urgent-care facility with a viral infection that would “run its course,” Brumley’s symptoms—including severe headaches—got worse. Brumley reportedly went to the emergency room several times but was sent home each time with over-the-counter pain medication. It was only when his face became swollen and lost muscle movement that doctors performed an MRI, which revealed a sinus infection that had “penetrated through the bone into the blood vessels in the brain,” Brumley’s aunt told People. Doctors performed s

Drinking the Recommended Amount of Alcohol May Still Shorten Your Life

U.S. drinking guidelines are too boozy, according to a new study. The research, which analyzed data from nearly 600,000 people in 19 countries, found that drinking more than 100 grams of pure alcohol per week (the equivalent of about seven standard drinks in the United States) was linked to an increased risk of early death during the study period. But many countries have drinking guidelines that consider 100 grams of alcohol a week to be well within the range of "safe" drinking. For example, U.S. guidelines recommend that men drink no more than 196 grams per week, or 14 standard drinks. (For women, U.S. guidelines fall within these recommended amounts, at no more than 98 grams a week.) In Ca

A Man Developed 'Thunderclap Headaches' After He Ate the World's Hottest Pepper. Here&#3

There’s a cautionary tale in this week’s BMJ Case Reports journal, and it’s frightening enough to make anyone think twice about downing super spicy foods. According to doctors at Bassett Medical Center in Cooperstown, New York, a patient there developed excruciatingly painful headaches—known as thunderclap headaches—after eating the world’s hottest chili pepper. It all started when the unidentified 34-year-old male entered a hot-pepper-eating contest, during which he consumed one Carolina Reaper pepper. The little red fruit was bred specifically for its spiciness, and it currently holds the Guinness World Record for the highest number of Scoville Heat Units, a measurement of chemical compoun

Back pain is common in highly active older adults

In a Journal of the American Geriatrics Society study, many well-functioning and highly active older adults experienced back pain, which was linked with poorer perceived and observed walking endurance. “Older adults are living longer and healthier active lives, so paying attention to conditions that may threaten independent function is increasingly important,” said lead author Eleanor Simonsick, of the National Institute on Aging. “In this study, we found that back pain affected nearly half of well-functioning, highly active older adults. We also found that back pain was linked to less energy efficient walking and poorer endurance, which can lead to walking difficulties. These findings sugge

Cervical spine injury reduced risk to use with helmet during motorcycle crashes

Despite claims that helmets do not protect the cervical spine during a motorcycle crash and may even increase the risk of injury, researchers from the University of Wisconsin Hospitals and Clinics in Madison found that, during an accident, helmet use lowers the likelihood of cervical spine injury (CSI), particularly fractures of the cervical vertebrae....More Source: Journal of Neurosurgery Publishing Group Reference: Page PS, Wei Z, Brooks NP.
