MRI scans are strong diagnostics with high-definition images of what lies inside a body. Strong magnetic fields require precaution, as brought out by an instance where a young woman suffered very serious injuries due to an oversight in a metallic core within a silicone sex toy that she happened to have before the MRI scan. This makes a stark reminder about the potentially deadly consequences of missing metal objects when such procedures are being performed. In April 2023, a 23-year-old woman went into an MRI with a silicone plug containing a metal core that was not known.
She thought that the item is made entirely out of silicone according to the advertising. However, the strong magnetic field of the MRI machine interacted with the hidden metal, dragging the object through her body and causing excruciating pain. According to reports from the U.S. Food and Drug Administration (FDA), the scene was harrowing, with the woman screaming in agony and requiring immediate hospitalization. Despite pre-scan screenings, which are routine prior to a scan, the patient did not inform the facility that the object existed because he presumed it was purely non-metallic. This caused serious injuries that led to the patient's law suit against the manufacturer for deceitful misrepresentations of material content.
MRI machines employ magnets between 0.5 to 3 Tesla (T). This is thousands of times stronger than the Earth's magnetic field. The tremendous force causes ferromagnetic materials, like iron and nickel, to be magnetized quickly and become strongly attracted toward the magnet. Objects as small as hairpins or paper clips will accelerate at 40 miles per hour inside the magnetic field.
The force can lead to catastrophic injuries in items lodged within the body, such as metallic implants or foreign objects. Metallic cores within devices, like pacemakers or intrauterine devices, must be disclosed to radiologists to prevent such complications.
On these claims, Dr. Adam Taylor, a specialist in human anatomy, weighed his words in a international health website and added that the distance away and mass of this object would increase its velocity towards that of sound, "The acceleration would be phenomenal, but with a metallic core, it can't go anywhere near supersonic speeds. As for the size, the magnetic acceleration to the internal soft tissues would ensure that there could be severe intracranial trauma."
The injuries inflicted in this case likely involved damage to major blood vessels, nerves, or organs, highlighting the devastating impact of even minor oversight during an MRI scan.
This is not an isolated case. There are documented cases of metallic objects causing serious damage during MRI scans with a 65-year-old man with schizophrenia swallowed metal objects, including sockets and a hinge pin. The powerful magnetic field during an MRI scan caused the objects to rupture his stomach, resulting in serious injuries.
A toddler who ingested 11 small magnets perforated his bowel while undergoing a scan, making his case unique. In another deadly but extremely rare incident, there have been people who hide a firearm on themselves during MRI procedures. Magnetic attraction can trigger a discharge in a weapon and has led to some fatal injuries.
These cases emphasize the very strong need for adequate screening and patient education prior to an MRI.
Medical professionals have been trained to avoid risks. This is by properly screening a patient for metallic objects. In general, most pre-scan protocols include:
The case emphasizes the importance of product labeling by manufacturers, especially those products that are likely to unintentionally cause harm to health. The patient's assumption that her device was 100% silicone points to a larger problem in consumer markets with misinformation.
It also reminds the patients to report any possible dangers to the medical professionals, no matter how the objects look non-metallic. In sensitive cases, patients can request private discussions with healthcare providers to ensure safety without discomfort.
In the end, it is a joint effort from manufacturers, healthcare professionals, and patients that can prevent such tragedies. Manufacturers must ensure truthful marketing, while healthcare providers should educate patients about the dangers of metal objects in MRI settings. For patients, understanding the risks and actively participating in pre-scan disclosures can be lifesaving.
This young woman's experience is a sobering example of the unforeseen dangers posed by MRI machines when precautions are overlooked. It serves as a wake-up call to address gaps in patient awareness, medical protocols, and product transparency. By learning from this incident, the medical community and the public can work together to ensure MRI scans remain a safe and effective diagnostic tool.

Hepatitis B: Changes in hepatitis B vaccine schedule in children could lead to resurgence of the disease, warn health officials. This comes after the Vaccine advisers for the US Centers for Disease Control and Prevention (CDC), known as the Advisory Committee on Immunization Practices (ACIP) met on Thursday to discuss the hepatitis B vaccine guidelines for newborns. The meeting was held to discuss the potential changes to the childhood immunization schedule, the vote is delayed until Friday.
However, there are several changes suggested that say only infants born to mothers who test positive for hepatitis B, or whose status is unknown would receive the birth dose. The potential changes also hint that babies whose mothers test negative could delay their first dose until the baby is two months old, instead of receiving it within the first 24 hours.
According to the local health experts, these guidelines could lead to a resurgence of the disease. These guidelines have been in place since the 1990s. Dr Hector Ocaranza, El Paso Health Authority, as reporting by KFoxTv, said, "This vaccine can be considered a vaccine that is going to be preventing cancer because hepatitis B virus is considered a carcinogen, meaning that this virus is going to cause liver cancer, and that's what we're trying to prevent in children."
Ocaranza further noted, "Changing the recommendation is going to create a lot of those infections coming back, and we're going to start seeing children that are going to be infected with a hepatitis B virus."
Doctors and scientists have noted that if the vaccine is delayed from birth to two months, it could lead to at least 1,400 new infections, 300 cases of liver cancer, and 480 preventable deaths every year. The shift would also add more than 222 million dollars in extra healthcare costs annually.
While there are mixed reactions in the community, the medical community mostly agree on the fact that vaccine should be mandatory for all children. Many stress on the importance of vaccines at birth. While the recommendation is not final yet as ACIP is to set to revisit the proposal tomorrow. Even if it passes, it requires approval from the CDC director before it becomes a national guidance.
As for now, no new evidence on harms of the vaccines has been revealed. The vaccine is administered to 1.4 bullion for more than three decades. Experts have pointed out that the vaccine has a "stellar safety record". This was also presented during the meeting. In fact, two members also demanded the evidence of any harm from the vaccine while pointing to its benefits. However, the members were interrupted by the vice-chair. Most members in the committee are hand-picked by the anti-vaxxer US health secretary Robert F Kennedy Jr, and those members too are long time anti-vaccine advocates.
This is not the first time discussion on delaying safe and life saving vaccines are taking place. Previous meetings where advisors recommended restricting access to COVID vaccines, and measles, mums and rubella, and chickenpox vaccines have already been taken.
The experts point out that infant immunization is directly linked to a 99% decline in acute hepatitis B cases in children, adolescents and young adults between 1990 and 2019. Experts also point out that holding discussions on well established vaccines without changing recommendation, too gives an impression that science is not clear, pointed Debra Houry, who was the chief medical officer of the CDC until this year, as reported by Guardian.
“For parents, they’re going to be very confused. They might question the whole vaccine schedule, or why things are done the way they are," Houry said.

Malfunctioning glucose sensors made by Abbott Diabetes Care have been tied to more than seven hundred serious medical events and seven possible deaths, according to updates from both Abbott and the Food and Drug Administration (FDA). The company issued a public notice on November 24 and sent letters to those who may be affected, explaining that it had begun a “medical device correction” for select FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors.
On December 2, the FDA released an early safety communication, which is the type of alert shared when a product is corrected or removed because of a significant risk before the agency can determine whether an official recall is necessary.
Some FreeStyle Libre 3 sensors may show falsely low blood sugar levels, which can lead people with diabetes to make treatment choices that are not appropriate for their actual condition. When someone’s glucose appears low, they might delay their insulin dose or skip it altogether, or they may eat more carbohydrates in an effort to raise their levels, as noted by USA Today.
When treatment decisions are based on incorrect readings, blood sugar can quickly become unstable. Poor glucose control can result in dangerous medical complications, including injury or even death. Problems linked to mismanaged diabetes can include diabetic ketoacidosis, heart issues, stroke, kidney damage, nerve and eye problems, and a higher chance of infection.
USA Today reports that the issue affects nearly three million Libre 3 and Libre 3 Plus sensors sold in the United States, and Abbott estimates that roughly half of them have already been used or have expired. Worldwide, the company has received 736 reports of severe adverse events (57 in the U.S.) and seven reports of deaths (none in the U.S.) that may be associated with this problem.
Only specific FreeStyle Libre 3 and FreeStyle Libre 3 Plus Continuous Glucose Monitoring Systems are affected. The FreeStyle Libre 3 handheld reader and mobile app are working normally.
No other Libre devices (FreeStyle Libre 14-day, FreeStyle Libre 2, FreeStyle Libre 2 Plus, or the FreeStyle Libre Pro sensors) or Abbott biowearable products are involved.

The serial number for a FreeStyle Libre 3 or FreeStyle Libre 3 Plus sensor is available in the app or reader, and it is also printed on the label at the bottom of the sensor applicator or on the carton. Consumers who are wearing a sensor that has been confirmed as part of the affected group should stop using it at once and safely discard it.

The Centers for Disease Control and Prevention’s vaccine advisory committee will meet on Thursday and Friday to review the childhood vaccination schedule, look at adjuvants and possible contaminants, and revisit hepatitis B immunisation guidance.
This will be the third gathering this year of the Advisory Committee on Immunization Practices (ACIP) after Health and Human Services Secretary Robert F. Kennedy Jr. dismissed all 17 former members and brought in his own choices, many of whom have openly questioned long-standing vaccine policies.
It is also the first meeting since ACIP chair Martin Kulldorff, a former Harvard Medical School professor, accepted a permanent job at HHS. Pediatric cardiologist and former U.S. Air Force flight surgeon Dr. Kirk Milhoan will lead the committee during this session.
The latest battle in the US’ growing political, cultural, and scientific debate over vaccines will unfold inside a CDC meeting room in Atlanta later this week.
There, a key CDC advisory group — now entirely appointed by Kennedy who will vote on proposals that could significantly change long-accepted guidance meant to shield newborns from hepatitis B, a virus known to cause liver cancer.
The two-day ACIP meeting comes shortly after Kennedy instructed the CDC to alter language on its website, downplaying the agency’s long-standing statement that vaccines do not cause autism, even though extensive research has repeatedly found no connection.
Here is what public health experts say they will be watching during this week’s meeting, which will be livestreamed on Thursday and Friday.
According to the meeting agenda, Thursday’s discussions and votes will centre on major changes to hepatitis B guidance. Overnight, the committee released draft wording for two recommendations.
As per CNN, the first proposal would shift the current universal recommendation for newborn hepatitis B vaccination to an “individual-based decision” made by parents and a healthcare provider for babies born to mothers who test negative for the virus or whose status is unknown.
The language also gives parents and clinicians the freedom to “decide when or if their child will begin the HBV series.”
The second vote concerns draft wording that encourages parents to talk with clinicians about blood tests to check immunity levels before later hepatitis B doses. The draft states that insurance should cover these tests.
Currently, all newborns are advised to receive the vaccine shortly after birth to protect against infection from an undetected maternal case and from close contacts who may unknowingly carry the virus.
Committee members have previously urged better hepatitis B screening during pregnancy, while others have questioned whether only high-risk infants should get the vaccine.
Hepatitis B is highly contagious. It spreads through contact with infected blood and bodily fluids, often from people with no symptoms. While it can be passed during birth, through sex, or shared needles, it can also spread through shared items found in many homes: nail clippers, toothbrushes, and even certain pieces of jewellery.
Childhood And Adolescent Immunisation Schedule
It is not yet clear what parts of the schedule will be reviewed. The early agenda listed this topic for Friday without details. The final agenda shows that attorney Aaron Siri, a close adviser to Kennedy, will speak on this.
Critics, including Kennedy, have raised questions about the number of vaccines children receive and the timing between doses.
According to ABC News, the draft agenda included a Friday session on adjuvants and contaminants. The final programme describes the talk as examining aluminium exposure from vaccines before 24 months and rates of persistent asthma between ages 24 and 59 months.
Aluminum salts are used in several vaccines — including diphtheria, tetanus, acellular pertussis, hepatitis A, and hepatitis B—to strengthen the immune response, according to CNN.
The ACIP meeting also follows last week’s internal FDA memo claiming that Covid-19 vaccines may be connected to the deaths of ten children. Lakshmanan, O’Leary, and others say the committee could raise the issue during the discussions.
