Over spring break, I spent a day in Tombstone, Arizona. This is the town where, if you don’t know the story, Wyatt Earp and his brothers, accompanied by their friend Doc Holliday, had a shootout with a group of cattle rustlers at the OK Corral. Though the Earp brothers wore the badges, when the tale is told the hero is usually Doc Holliday—noted gambler, crack shot, prodigious drinker
US government’s premiere test program finds cancer risk from cell phone radiation: a game-changing global wake-up call
Have you heard that cell phones cause cancer, then they don’t, then they do? Confused enough yet? Let me break it down for you. Contrary to some claims, the new US government study by the National Toxicology Program (NTP) is hardly a shot in the dark or a one-off event. With this largest best-conducted animal study, we now have three different studies within the past six years
Preimplantation genetic screening: after 25 years and a complete make-over, the truth is still out there
More than 25 years ago, it was found that human embryos of about three days old cultured in the lab, showed chromosomal abnormalities in more than half of them. Many of these abnormalities were not coming from the sperm or the egg, but occurred after the embryo has cleaved two times, obtaining four cells, or three times, reaching the eight-cell stage.
When looking at the use of drugs in modern medicine, specifically anaesthesia and intensive care – it is important to realise that this is nothing new at all. The first attempts at general anaesthesia were most likely herbal remedies and opiates, evidence of which has been found as early as the third millennium BCE. Antiseptics, from the Greek words anti (against) and sepsis (decay) were also used in ancient times
Clinical pathology covers a broad range of responsibilities and functions in medicine. As a discipline, it includes clinical (bio)chemistry, medical microbiology, hematology, coagulation, clinical immunology, and increasingly molecular diagnostics. We recently sat down with the Editor of the American Journal of Clinical Pathology, Dr. Michael L. Wilson, to learn the vital importance of this field.
Coronary artery disease is the leading cause of death in many countries, but its prevalence has changed significantly during the last 50 years. Death rates from heart disease have fallen dramatically in western countries, but increased in many ‘developing’ countries. These large population-wide changes suggest environmental factors, including diet, are a major determinant of the risk of heart disease.
Cancer cells have a unique vulnerability: the same mechanisms that shield them from the immune system also make them prone to viral infections.
Psychosis, agitation, disorientation, or bizarre behavior due to drug ingestion is a common presentation to the emergency department (ED), and frequently psychiatry is consulted to assess for an underlying psychiatric illness. A working knowledge of how different substances are expected to affect patients is an important part of keeping up-to-date as a psychiatric emergency clinician.
When I first met Ian Waterman in the mid-1980s I could scarcely believe him. He claimed to have lost touch, and movement and position sense (termed proprioception) below the neck, though he could still feel pain and temperature, and his movement nerves were unaffected. Not only was I not aware of any such condition in medicine, but he had walked to the clinic and was sitting calmly as we chatted.
A month before Joan of Arc’s heresy was cleansed by fire on this day in 1431 CE, a spokesman for her Burgundian accusers railed against her: “O Royal House of France! You have never known a monster until now! But now behold yourself dishonored in placing your trust in this woman, this magician, heretical and superstitious.”
We’re all quite familiar with having five senses: sight, touch, taste, smell, and hearing. These senses help us understand the world outside our body. The idea of five senses is so ingrained that having a ‘sixth sense’ is a clue that something isn’t right. But what about other physical sensations?
Alcoholics Anonymous has provided millions of people with a chance at recovery from addiction. There is one aspect of membership for some members that most people, even addiction specialists, are not aware of, namely, the remarkable transformation that many AA members call a spiritual awakening. It’s a remarkable phenomenon for anyone interested in social science on the addictions.
When travelling the globe, most intrepid adventurers and holiday-makers will encounter only minor health problems. But knowing and understanding possible hazards is fundamental to preventing them. When planning an adventure, people often seek novel experiences – and contemporary travel is able to take us (within just a few hours) from a relatively benign environment to a potentially life-threatening setting.
Several widely circulated opinion pieces assert that because there is no detectable increase in all brain cancers in Australia in the past three decades, cell phones do not have any impact on the disease. There are three basic reasons why this conclusion is wrong.
Dementia, from the Latin demens, is a persistent disorder of the mental processes marked by memory disorders, personality changes, and impaired reasoning. It affects 47.5 million people worldwide, and there are 7.7 million new cases annually. This year’s Dementia Awareness Week (15-21 May 2016) aims to bring recognition and awareness to this neurological illness.
All over the world, populations are changing. People are living longer, and older people are forming a larger percentage of the global population. Baby boomers are retiring and improved health care has extended life expectancy. At the same time, as globalisation and urbanisation break apart familiar social and family structures, more older adults are living alone or without social support.
