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.

How Metal Objects Interact with MRI Fields?

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.

Preventing MRI-Related Incidents

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:

• Patients are interrogated about implants, recent surgery or exposures at work related to metals.
• Radiologists sometimes use handheld metal detectors to search for hidden items.
• People who work with metal, like welders or machinists, will need additional testing to detect microscopic metal fragments within soft tissues or eyes.

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.

Newly released national sexual health data shows that Australia is seeing an alarming rise in STIs like syphilis and gonorrhoea. The data from Kirby Institute at UNSW Sydney shows that diagnoses have increased by more than 50% over the past decade.

In 2025, Australia recorded 5,986 syphilis diagnoses and 42,393 gonorrhoea diagnoses, with rates of both infections shooting up by more than 50% since 2016.

Apart from the sharp rise in cases, one pattern that has drawn attention is the difference in the number of infections between men and women. Syphilis diagnoses among women increased 167% over the past decade, compared with a 39% increase among men.

Health experts say the rise is especially alarming as syphilis, when left untreated, can cause miscarriage, stillbirth, congenital syphilis and infant death.

Signs Of Syphilis Can Vanish Without Actually Leaving The Body

Syphilis is caused by the bacterium Treponema pallidum and the infection unravels in stages. The first stage causes a painless sore, called a chancre, typically at the site where the bacteria entered the body. The sore can occur around the genitals, anus, rectum, lips or mouth and may disappear on its own within weeks.

The disappearance of that sore could be misleading because when it heals, it does not mean that the infection has not necessarily gone away.

Without treatment, syphilis can progress to a second stage, which comes with a rash, swollen lymph nodes, fever, fatigue, and other symptoms. These symptoms can also eventually disappear.

If left untreated, the infection can then enter its latent stage, when a person has no visible signs or symptoms. This is what makes syphilis particularly difficult to detect.

During latent syphilis stage, the bacteria remain in the body even though the person may feel completely well. According to the US Centers for Disease Control and Prevention, untreated syphilis can remain in the body for years.

Rising Syphilis Cases In Women Women May Impact Pregnancy

The latest Australian data show men accounted for 78% of syphilis diagnoses in 2025, but the much faster increase among women is raising particular concern because an infected pregnant woman can pass the bacteria to her unborn baby.

Dr Skye McGregor, an epidemiologist at the Kirby Institute said, “It’s really concerning because the rise among women has contributed to syphilis in pregnancy, which can cause miscarriage, stillbirth, congenital syphilis and infant deaths,” McGregor said. “These are really substantial impacts on infants, but also the community as a whole. Across that same 10-year reporting period, there were 113 congenital syphilis cases and, tragically, 40 of those infants died.”

Australia recorded 14 cases of congenital syphilis in 2025. Over the past decade, there have been 113 reported congenital syphilis cases, with 40 resulting in infant deaths.

The infection is preventable from reaching the baby when it is identified and treated during pregnancy. To curb the same, Australia has recently updated national guidelines to recommend at least three syphilis tests during pregnancy, reflecting concern about rising infections.

What Happens If Syphilis Is Left Untreated For Years?

Not everyone with untreated syphilis develops latent-stage disease. But in some people, the infection can eventually damage multiple organs.

Tertiary syphilis can affect the heart and blood vessels, brain and nervous system, and several other organs. It can emerge 10 to 30 years after the original infection and can cause severe disability or death.

Syphilis can also affect the nervous system, eyes or ears at different stages of infection. Neurosyphilis can cause headaches, weakness, problems with movement, confusion or cognitive changes.

Ocular syphilis can cause vision problems and potentially permanent vision loss, while otosyphilis can cause hearing loss, tinnitus or dizziness.

India’s Ministry of Health and Family Welfare has issued an advisory stating that stem cell therapy should be used as standard care only for diseases or indications approved by the Ministry.

The advisory reiterates the existing regulatory framework governing stem cell research and therapy.

What Does The Advisory Say?

The advisory directs that stem cell therapy for Autism Spectrum Disorder (ASD) be restricted to approved clinical trials.

This aligns with the National Guidelines for Stem Cell Research, 2017, issued by the Indian Council of Medical Research (ICMR) and the Department of Biotechnology (DBT), along with other applicable government instructions.

The advisory also says unproven stem cell interventions, including those for ASD, should not be offered as “routine, standard or commercial clinical services.”

“All States and Union Territories must adopt the Clinical Establishments (Registration and Regulation) Act, 2010, regarding regulation of stem cell therapy,” the Ministry said.

The directions apply to government and private clinical establishments involved in stem cell research, treatment, promotion or administration.

The Supreme Court had earlier ruled against the use of stem cell therapy for autism outside approved clinical trials. The National Medical Commission (NMC) has also warned doctors and hospitals against offering it as routine treatment for ASD.

Action Against Violations

The Ministry has asked States and Union Territories to ensure that hospitals, clinics and other establishments involved in stem cell research or treatment comply with the regulatory framework.

The Supreme Court, in its January 30, 2026 judgment, said violations can lead to professional misconduct proceedings, as well as action under the Clinical Establishments Act, including cancellation of registration and penalties.

In its September 5, 2026 advisory, the National Medical Commission (NMC) said stem cell therapy can be offered as standard clinical care only for approved indications.

Unauthorized administration, prescription, promotion or advertising of stem cell therapy beyond approved indications may amount to professional misconduct, it said.

State Medical Councils have been asked to examine alleged violations and take disciplinary action where professional misconduct by a registered medical practitioner is established after due process.

Which Diseases Can Be Treated With Stem Cells?

Earlier this year, ICMR Director-General Dr Rajiv Bahl told the NMC that stem cell treatment could be used in regular medical practice only for 32 government-approved diseases.

These include:

• Acute myeloid leukemia
• Thalassemia
• Multiple myeloma
• Aplastic anemia
• Myelofibrosis
• Germ cell tumors

The ICMR DG asked doctors not to offer stem cell therapy for diseases outside the approved list. Current international guidelines also do not recommend stem cell therapy as a treatment for ASD.

What Did The Supreme Court Say?

In January, a Supreme Court bench comprising Justice JB Pardiwala and Justice R Mahadevan said stem cell therapy lacks “scientific support” and has not been recognized as a sound medical practice backed by empirical evidence.

The Bench ruled that “every use of stem cells in patients outside an approved clinical trial is unethical and shall be considered as malpractice.”

The Court said stem cell therapy can still be studied through monitored clinical research trials, and patients can participate in approved and regulated trials.

What Is Stem Cell Therapy?

Stem cell therapy, also called regenerative medicine, uses stem cells to repair or replace damaged tissues.

While stem cell therapy is used for certain blood cancers and blood disorders, there is no established scientific evidence supporting its use as a treatment for autism.

Stem cell therapy remains vastly unregulated in India, and some private labs have been making money by promising treatment for autism, according to experts.

Stanford University scientists have grown lab-made human brain tissue inside mice, successfully creating a new kind of animal model whose constitution is the closest to those of humans. This could help researchers study brain development and neurological diseases in living organisms with a lot more accuracy.

The study, published in Nature recently, discusses mice whose cerebral cortex was largely replaced by human brain tissue grown from stem cells.

The human tissue expanded to occupy more than 90% of the space available for the mouse cortex and formed connections with the animals' nervous systems successfully.

The researchers call them xenocortical mice. The breakthrough could provide scientists with a way to study human neurons in a living brain, something that cannot be done directly in people and is difficult to reproduce using conventional laboratory models.

How Did Scientists Create A Part-Human Brain In Mice?

The researchers first genetically engineered mice so that most of the cells destined to form their cerebral cortex and hippocampus would not develop. This created space for human brain tissue.

Then they transplanted human cortical organoids, three-dimensional structures made from human stem cells, into the brains of newborn mice.

The organoids were able to grow rapidly inside the animals. In successful transplants, the human tissue expanded nearly five-fold over a period of three months and eventually occupied more than 90% of the available cortical space.

The human cells also developed different types of neurons and formed connections with the mouse brain and, in some cases, extended nerve fibres into the spinal cord. It is important to note that these are not mice with an entirely human brain.

The animals still have a mouse nervous system, including their sensory organs and deeper brain structures. What has been humanised is the cortex, the outer part of the brain involved in functions including perception, learning, and complex information processing.

Why This Could Be A Milestone For Brain Disease Research?

One of the biggest problems in neuroscience is that findings in mice do not always translate to humans.

Human brain organoids grown in laboratory dishes have helped researchers study development and disease, but they lack many features of a living brain. They do not receive normal sensory information or interact with muscles and other organs. Putting human neural tissue inside a living animal provides that missing environment.

The Stanford researchers tested the model by exposing the mice to a temporary lack of oxygen. The human cortical cells showed significant damage, and the animals developed movement and coordination problems. This provided a way to observe how developing human neural tissue responds to an injury inside a living organism.

The researchers say the approach could eventually help investigate conditions including cerebral palsy, epilepsy, autism, schizophrenia and other neurodevelopmental or neurological disorders, while also providing a platform for testing potential treatments.

Ethical Questions

The experiment also raises difficult ethical questions. As scientists become increasingly capable of integrating human neural tissue into animals, researchers must consider whether increasingly sophisticated brain models could acquire unexpected characteristics or alter animal welfare.

The Stanford team sought outside ethical review of the work. Experts have emphasised that there is currently no evidence that these mice possess human-like consciousness, but they also argue that ethical oversight will become important as these models become more complex.
