Do hair dyes increase cancer risk?
This study also had several limitations. First, participants were female nurses of mostly European descent, meaning the findings are not necessarily generalizable to men or to other racial or ethnic groups. Next, the study could not account for every single cancer risk factor (for example, exposure to pesticides and other environmental chemicals). Data were not collected on other hair grooming products beyond hair dyes, and subjects may have mistakenly reported use of permanent hair dyes when they were in fact using semi-permanent or natural dyes. Without data on actual color of hair dyes used, the authors assumed that hai...

More intensive treatment of DCIS reduces the risk of invasive breast cancer
This study showed that increased cancer risk persisted for more than 15 years after a diagnosis of DCIS, and that more intensive therapy than lumpectomy alone — whether with mastectomy, radiation therapy, or endocrine therapy — reduced the risk of invasive breast cancer among women with DCIS. The lowest risk of invasive breast cancer was in women who chose mastectomy.
The risk of invasive breast cancer was seen regardless of severity of DCIS. Women who had low- or moderate-grade DCIS, as well as high-grade DCIS, had long-term increased risk.
Women who are recently diagnosed with DCIS should work with their treatment te...

My Benjamin Hartman Story
“I need intravenous Beefsteak,” I texted my forever-Beefsteak date Ben Hartman, who others called Benjie or Bean or sometimes Boozey, and who I called Kryptonite or sometimes Sushi Ben. “See you there at 6:30,” he texted back. Since meeting in 2014, we each accommodated the other when it came to Beefsteak — a fast-casual restaurant near George Washington University that served paleo-friendly fare before paleo was cool and offered outdoor seating long before covid-19. My gcalendar archive shows that we made seven Beefsteak dates in advance, though that’s a fraction of our total as most stemmed fro m mi...

Digital Otoscope Enhances Decision-Making and Improves Outcomes
Procedural equipment will help you make accurate diagnoses and formulate treatment plans. You want the equipment to work, be readily accessible, and be easy to clean and store. It's also nice when it fits in your pocket.You also want to be sure your staff is trained to use it. Not everyone in your department may want to break out the nasal endoscope for a quick ENT exam, as we discussed last month. (See post below.) But specialized ENT equipment may make your life a bit easier and improve patient outcomes. Using a digital otoscope to view the tympanic membrane is fast, easy, and safe. This particular model costs $24. ...

In conclusion, all NAFLD histological stages were associated with significantly increased overall mortality, and this risk increased progressively with worsening NAFLD histology. Most of this excess mortality was from extrahepatic cancer and cirrhosis, while in contrast, the contributions of cardiovascular disease and HCC were modest.

Hepatitis A in the United States
Few Americans are aware of a major epidemic that has taken hold of large areas of their country in recent years – by a disease that is easily diagnosed and prevented. Sadly, public – and even professional interest in these events have been overshadowed by COVID-19.
AN UPTICK IN CASES
Hepatitis A had been largely under control until three years ago and can be easily prevented through the use of a safe and effective vaccine.
From January 2017 to January 2019, at least 26 separate outbreaks were reported, to a total of 11,628 cases and 99 deaths, nationwide. Homeless individuals and users of illicit dru...

Nanopropellers to Deliver Gene Therapy Into Cells
Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed powerful nanopropellers that can be steered into the interior of cells to deliver gene therapy. The magnets that these devices, each about the size of a bacteria, are made of were created for the first time for this very task.
Most powerful magnets are either not bio-compatible, lose their properties at small scales, or cannot be manufactured to have very fine details, so cannot be used to manipulate tiny objects from a distance and inside the body. To overcome this, the team created magnets using an iron platinum “L10”...

Is it time to give up your annual mammogram?
If you dread your annual mammogram, you’re not alone. For many women, this breast cancer screening examination can be painful, stressful, and just an overall hassle.
You may wonder, are you old enough to give it up? If you’re over age 75, the answer is: maybe or maybe not. The fact is, breast cancer screening isn’t right for all older adults, but there’s no expert consensus on the right age to stop. This is mostly because scientific evidence in this area is lacking, says Dr. Kathryn Rexrode, associate professor of medicine at Harvard Medical School and chief of the Division of Women’s Health at Brigham and Women...

Newer skin cancer treatments improve prognosis for those with cutaneous melanoma
Cutaneous melanoma, also called malignant melanoma, is the type of skin cancer that is most likely to spread to other parts of the body. Though melanoma accounts for only about 1% of skin cancers, it is responsible for more than 90% of skin cancer-related deaths.
But thanks to developments in skin cancer treatment (mostly in the last decade), patients with melanoma have much better chances of living longer.
What is a melanoma?
Melanoma involves the uncontrolled growth of a type of cell known as a melanocyte. One of the most important functions of a normal melanocyte is to protect your skin from the sun’s damaging ultravi...

Neuroendocrine tumors of GI Tract.
The World Health Organization (WHO) classifies neuroendocrine neoplasms as well-differentiated neuroendocrine tumors (either the primary tumor or metastasis) and poorly differentiated neuroendocrine carcinomas.Historically, well-differentiated neuroendocrine tumors have been referred to as “carcinoid tumors,” a term which may cause confusion because clinically a carcinoid tumor is a serotonin-producing tumor associated with functional manifestations of carcinoid syndrome.The use of the term “carcinoid” for neuroendocrine tumor reporting is therefore discouraged for these reasons.Immunohistochemistry and other ancil...
