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.

Scientists have discovered an Achilles' heel that helps some of the most aggressive cancers escape treatment. The discovery that could pave the way for new targeted therapies against specific drug-resistant tumours.

Researchers at Nanyang Technological University (NTU) Singapore, identified a protein called TEX264 that enables cancer cells to escape the therapeutic effects of a widely used class of targeted cancer drugs known as PARP inhibitors. The study is published in Nature Cell Biology.

What Does This Mean For Drug-Resistant Cancers?

The findings could have positive implications for patients with triple-negative breast cancer, as well as ovarian, prostate, and pancreatic cancers that are treated with PARP inhibitors. These cancers eventually become resistant to the drugs.

"Our findings have identified a new biological process involving TEX264 as a key mechanism of drug resistance in an aggressive form of cancer," said Professor Kristijan Ramadan, who led the research. "We coined this new biological mechanism 'autophagy of DNA lesions', or simply 'nucleophagy'. This makes TEX264 a potential target for future cancer therapies."

How Do Some Cancers Escape Treatment?

PARP inhibitors work by blocking PARP1, a protein that repairs damaged DNA inside cancer cells. Without this repair system, tumour cells accumulate DNA damage and die. However, many cancers eventually become resistant to this treatment.

The researchers discovered that TEX264 helps remove trapped PARP1 proteins from damaged DNA through a newly identified clean-up process called nucleophagy, allowing cancer cells to continue repairing themselves and escape the treatment. This is the cellular recycling system that makes cancer resistant to treatments.

When scientists blocked TEX264 in experiments, PARP1 remained stuck on DNA, DNA damage accumulated, and the cancer cells became far more vulnerable to therapy.

What Are PARP Inhibitors?

They are approved for several cancers, including ovarian, breast, prostate, and pancreatic cancer.

While many patients initially respond well, resistance develops in an estimated 40% to 70% of breast and ovarian cancer cases.

Importance Of This Study

Instead of targeting the DNA repair machinery directly, the new study targets an entirely different weak spot, the cellular cycle that cancer cells exploit to discard damaged repair proteins.

Researchers believe drugs that inhibit TEX264 or block nucleophagy could potentially restore the effectiveness of existing PARP inhibitors, offering a new targeted treatment strategy for patients whose cancers no longer respond to therapy.

The researchers caution that the findings are currently based on laboratory studies, and more research, including clinical trials, will be needed before therapies targeting TEX264 can reach patients.

The promising results adds to growing efforts worldwide to overcome one of oncology's biggest challenges: preventing cancers from evolving resistance to life-saving treatments.

The World Health Organization (WHO) has updated its treatment guidelines for visceral leishmaniasis (VL), commonly known as kala-azar, and post-kala-azar dermal leishmaniasis (PKDL).

Through this update, WHO is recommending shorter, safer and more patient-friendly treatments that could improve outcomes for thousands of patients across eastern Africa and South-East Asia.

The revised guidance marks the first major update in nearly two decades for these forms of leishmaniasis.

It introduces new treatment options, including the use of oral miltefosine in combination therapies, reducing the need for long courses of painful daily injections.

What Is PKDL?

Post-kala-azar dermal leishmaniasis (PKDL) is a skin condition that appears months or years after a patient recovers from visceral leishmaniasis.

Visceral leishmaniasis, also known as kala-azar or black fever, is a life-threatening parasitic disease caused by Leishmania. It is spread by infected female sandflies. It attacks internal organs like the spleen and liver and is almost always fatal if left untreated.

In post-kala-azar, while patients usually feel well, they develop patches, papules or nodules on the skin that harbour the parasite. This allows sandflies to transmit the infection to others.

Early diagnosis and effective treatment of PKDL are therefore considered essential for interrupting transmission and elimination of kala-azar.

About The New Treatment Guidelines

WHO now recommends a 14-day regimen combining oral miltefosine with once-daily paromomycin injections for patients with primary visceral leishmaniasis in eastern Africa.

The new approach replaces older sodium stibogluconate-based regimens that required 17 days of treatment, 34 injections, which were often associated with toxicity.

The guidelines also introduce shorter treatment options for PKDL. For patients in eastern Africa and South-East Asia, WHO recommends new combination treatments that substantially shorten duration. It also allows part of the therapy to be completed at home.

Dr Daniel Ngamije Madandi, WHO Director of Malaria and Neglected Tropical Diseases, "For too long, patients suffering from leishmaniasis have endured treatments nearly as punishing as the disease itself. By recommending safer, shorter and more patient-friendly regimens, we are not just improving care; we are accelerating our fight to eliminate this devastating disease and offering renewed hope to communities across Africa and Asia."

Milestone In PKDL Treatment

The updated recommendations also revise the safety guidance for miltefosine in line with advice from the WHO Advisory Committee on the Safety of Medicinal Products and introduce allometric dosing to help optimise treatment across different body weights.

Kala-azar is one of the world's deadliest parasitic diseases after malaria. According to WHO, eastern Africa accounted for nearly 79% of global visceral leishmaniasis cases in 2024, with around half of patients being children under the age of 15.

Transmitted through the bite of infected female sandflies, it causes prolonged fever, weight loss, anaemia and enlargement of the spleen and liver. If left untreated, the disease is fatal in up to 95% of cases.

Maharashtra Food And Drug Administration (FDA) has taken a significant step towards promoting healthy eating habits in children. On Wednesday, FDA commissioner Tukaram Mundhe announced that foods and drinks high in fat, sugar, and salt should not be sold within 50 metres of school premises.

"Within school premises and up to 50 metres from the school compound, the sale, advertisement and free distribution of high fat, salt and sugar (HFSS) food items is completely banned by the FDA. It will be implemented strictly," Mundhe said.

Why Did Maharashtra FDA Ban The Sale Of HFSS Food Items?

HFSS food items could neither be sold, advertised, nor distributed free of cost within the prescribed limits around schools in Maharashtra anymore.

The recent ban covers popular junk food items like vada pav, samosas, deep-fried snacks, chips, cold drinks, sugary beverages, chocolates and ice cream.

Mundhe said the state government had issued a compliance order on July 27 to enforce food safety and nutritional standards across educational institutions.

He also said that the move would affect nearly two crore students studying in around 1.08 lakh schools in Maharashtra.

The guidelines would apply to all government, government-aided and private schools affiliated to any education board, meaning that no educational institution would be exempt from the ban.

He also said that canteens, midday meal kitchens, food suppliers and hostel kitchens catering to schools must obtain mandatory registration and licenses under food safety regulations.

He added, "No organisation or institution can prepare or supply food to schools, hostels or under the midday meal scheme without registration and a valid license to operate."

He said school principals, headmasters and local authorities would play a key role in implementing the restrictions.

According to the guidelines, the move is applicable for children from 22 months of age up to students studying in Class 12.

HealthandMe spoke to Dr Rahul Verma, Director of Paediatrics and Neonatology at Sir H.N. Reliance Foundation Hospital, Mumbai, about the impact this move would have on children's health.

Dr Verma says that rather than viewing the decision only as a ban on junk food, it should be seen as an attempt to reshape children's food environment.

He says, "When healthier choices become the default in schools, children are more likely to develop better eating habits that can continue into adulthood. Reaching over 1.08 lakh schools and nearly 2 crore students from preschool to Class 12 gives this initiative the potential to influence an entire generation at a stage when lifelong dietary preferences are still being formed."

He also said that the policy also goes beyond simply removing HFSS foods. By making FSSAI licensing mandatory for school canteens, introducing regular compliance checks, and encouraging the inclusion of nutritious foods such as fruits, pulses, and whole grains, it creates a structured system that supports healthier eating rather than relying on restrictions alone.

In an X post, Dr. Sivaranjini, a pediatrician, suggested a different approach which seems to be a much simpler way of differentiating between healthy and unhealthy foods.

She wrote, " Front-of-pack label (FOPL) warnings are the simplest and most effective way to help people make better food choices in India. A clear “High in Sugar” or “High in Salt” or "High in Fat" warning takes seconds to understand. No calculations. No nutrition knowledge. Just a simple signal that says, 'Think twice'".

The doctor says that unhealthy, processed foods are often marketed as healthy due to misleading labels and claims on their packaging.

She added, "The problem with systems like Nutri-Score or Health Star Ratings is that they average everything into one score. A product loaded with sugar can still look “healthy” because it has added protein, fiber, or vitamins."

Providing real-life examples, she informed, "A sugary breakfast cereal still gets HIGH IN SUGAR, even if fibre and vitamins are added to it. An instant noodle high in sodium still gets HIGH IN SODIUM even if protein and vitamins are added to it. A packaged fruit juice with excessive free sugars still gets HIGH IN SUGAR, though it's directly from the fruit."

Although the move is a positive step towards protecting children's health, sustained success will depend on whether healthy food remains accessible, affordable, and appealing to children. If children continue to consume highly processed foods outside school or at home, the long-term benefits may be limited.
