Imagine this. A young teenager, 17, years old, who is fully developed. Now imagine this, the same teenager has a fully developed extra set of limbs and a pelvis. That extra set of pair is attached with chest artery. But, how can this happen?

While it is extremely rare, and has a chance of less than one case occurring per 100,000 births. Such things do happen. This is called parasitic twin.

What Is A Parasitic Twin?

It is an extremely rare type of cojoined twin where a baby is born with an underdeveloped twin attached to its body. This condition is also known as vestigial twins. The condition is very closely related to conjoined twins, where babies are connected at birth and share organs. However, the main difference is that in conjoined twins, there are two developed babies, whereas in parasitic twins, only one is fully developed, other one is underdeveloped and non functional.

In such a case, the twin who is developed is medically known as the autositic or the dominant twin. The dominant twin is healthy in most aspect but may have extra tissue, organs, or limbs from the parasitic twin.

The parasitic twin may be attached with the dominant twin through several places. The common joints are at the head, torso, chest, pelvis, buttocks, or back. In these cases, the parasitic twin is not alive and they die either in the womb or during the childbirth.

Doctors Remove Parasitic Twin

Now, let's go back to the case we referred to, where a young teenager had an extra pair of limbs attached to chest. The teenager who has not been named is from Uttar Pradesh's Unnao neighbourhood, and was treated in AIIMS, Delhi. The team of doctors successfully removed the extra set of limbs from his body.

Dr Asuri Krishna, who led the team of specialist who surgically removed the extra limbs told the BBC that only 40 to 50 cases of parasitic twins have been documented in world medical literature, and in those cases, the surgery had been attempted on children. The doctor said that without much medical literature to guide them, the team of doctors depended on "intuition, skill and knowledge".

The doctor shared that the child had two fully formed legs, buttocks and external genitalia, which weighed around 15kg "protruding from his abdomen".

How Was The Surgery Performed?

The doctor shared that first they identified how interconnected the parasitic and host twins were. The doctors took scans and found that parasitic twin was attached to the teen's breastbone. The blood was being supplied from a vessel in his chest. However, "there wasn't much connection with other main organs like the liver or kidneys," said Dr Krishna. The team also found a large cyst in the teen's abdomen.

Then the surgery was performed in two stages. In the first stage, the parasitic twin was removed. Then the cystic mass was extracted from the surrounded area. The entire surgery was completed in two and a half hours and the team of doctors included radiologists, anaesthetists, and plastic surgeons.

The biggest challenge was when the teen's blood pressure dropped as 30 to 40% of his blood flowed to the parasitic twin, however, the doctors were prepared for it and they stabilized him.

Ever tried logging off social media platforms like Facebook and Instagram? For many, checking notifications, scrolling through feeds, and engaging with content has become second nature, often leading to an unnoticed addiction.

While digital dependence can significantly impact mental health, relationships, and overall well-being, most people don’t realize how much time they’re actually spending online.

To understand its effects, researchers at Stanford University in the US asked the 36,000 study participants to log off on weekends from their Facebook and Instagram accounts. The results showed that the people who stayed off felt measurably better.

Disconnecting from social media was seen as a powerful way to regain balance and focus in the increasingly connected world.

The study split participants into groups: about 275 were paid to deactivate their accounts for six weeks, while others logged off for just one week. Both groups showed improved emotional well-being compared to those who kept scrolling, but the effect was more pronounced for Facebook users who went longer without it.

Facebook users over 35 showed the biggest mood improvements, while among Instagram users, the 18-to-24 group benefited most.

Social Media And Mental Health

An increasing number of studies and the community at large are convinced that social media are detrimental to our mental health and general well-being.

According to a recent YouGov poll taken in the UK in January 2026, 37 percent of adults gave a general negative review of social media's impact on their mental health, more than twice the number of people who say otherwise.

Merely 14 percent of them admitted to receiving a positive effect from social media on their mental health.

The Pew Research Center survey, conducted in 2024, discloses that 45 percent of US teenagers think social media is damaging their sleep, and 40 percent believe it is hurting their productivity, which are both key factors of mental health.

In 2023, former US Surgeon General Vivek Murthy named social media as a major threat to the mental health of teens. He also released a social media advisory about social media and mental health.

The advisory indicates that frequent social media use could be associated with changes in parts of the brain related to emotions and learning. Additionally, it can affect impulse control, social behavior, emotional regulation, and sensitivity to social punishments and rewards.

In serious cases, social media can also contribute to self-harm or suicidal thoughts, especially among teens and children facing cyberbullying or trolling. Young people are particularly vulnerable to online pressures, negative comparisons, and feelings of rejection.

“Excessive social media exposure has been linked to anxiety, depression, sleep disruption, and, most importantly, difficulty with regulating attention and emotions. Algorithms intensify comparison, validation-seeking, and exposure to harmful content, which children lack the maturity to process,” Dr. Sachin Pradeep Baliga, Associate Consultant Mental Health & Behavioural Sciences, Fortis Healthcare, told HealthandMe.

Is Quitting The Only Option?

According to mental health experts, moderation and mindfully controlled usage could be the key.

It is far more effective to come up with a plan that helps your interaction with social media platforms be healthier, such as limiting your time on social media platforms, avoiding harmful content, and pursuing real-world connections, rather than completely demonizing social media.

A team of researchers at the All India Institute of Medical Sciences (AIIMS) in Patna has made a significant breakthrough in understanding the link between heatstroke and fatalities.

The study published in the Medico-Legal Journal identified a specific brain center and vascular injury patterns that play a crucial role in heatstroke-related deaths.

The research team discovered that the anterior hypothalamus, which serves as the brain's primary temperature-regulating center, undergoes severe structural damage during heatstroke. This damage is found to be a key factor in the fatal outcomes associated with heatstroke.

“The study establishes that the anterior hypothalamus undergoes critical structural damage during heat stroke, making it a central driver of fatal outcomes. The injury in the hypothalamus can be used as definitive evidence in the forensic diagnosis of heat-stroke deaths,” said lead author Dr Ashok Kumar Rastogi, forensic expert, in a statement.

The finding can be a major step forward in the scientific basis for diagnosing heat stroke deaths through post-mortem examination, an area that has often posed challenges for autopsy surgeons in establishing a definitive cause of death, the researchers said.

It will also help address a long-standing medico-legal issue, particularly in the context of compensation, insurance claims, and death benefits for the families of victims.

How Was The Study Conducted?

The study was conducted by the Department of Forensic Medicine at AIIMS Patna in collaboration with the Department of Anatomy and Pathology.

The study was based on detailed post-mortem investigations of individuals exposed to extreme environmental conditions in the Patna region during 2024, including temperatures reaching 48 degrees Celsius, humidity levels up to 95 per cent, and prolonged heat exposure lasting five to eight hours, the Institute said.

The results also outlined a vascular injury pattern associated with fatal heat stroke, helping build a clearer pathological profile of the condition under extreme heat exposure.

The researchers noted that the findings could strengthen forensic investigations and support more scientifically grounded death certification in suspected cases.

Heatstroke is a medical emergency with a high case fatality rate. The body’s inability to regulate internal temperature and eliminate heat gain in such conditions increases the risk of heat exhaustion and heatstroke.

Speaking to HealthandMe, Dr. Naval Vikram, Professor, Department of Medicine, at the AII India Institute of Medical Sciences (AIIMS), explained how heat stroke affects people.

“The general features of a patient with heat stroke are: first, his or her body temperature will be very high. It will not be around normal levels like 104, 105, or 106—it will be significantly elevated. Second, the person may be delirious, confused, or even in a state of unconsciousness or coma. The breathing will also be labored. These are the features of heat stroke,” Dr Vikram said.

The most vulnerable category for heat-related problems is the extremes of age—the younger children and older adults. The expert noted that younger children may not be able to express their symptoms completely. They may not be able to tell you exactly what they are feeling.

At the other end, older adults often have multiple health issues—neurological conditions, diabetes, hypertension, and kidney problems.

How Can One Prevent?

Try to avoid exposure to extreme heat as much as possible.

Adequate hydration is key.

One must cover the head and upper body, use an umbrella, stay hydrated, and take breaks in between.

If you have to work in a hot environment for a couple of hours, take a break in a cooler or temperature-controlled environment for at least half an hour before resuming, rather than continuously working in the heat.

Recent photographs of former US President Donald Trump with the UK’s King Charles III have drawn attention after visible discoloration was observed on his left hand, raising fresh questions about his health.

While Trump’s right hand has appeared discolored in earlier public appearances—a concern previously downplayed by both the former president and the White House—the latest images show similar changes on his left hand as well.

“Trump's right hand has been in bad shape for a long time now, but this picture taken today shows discoloration on the back of his left hand," independent journalist Aaron Rupar wrote on social media platform X.

Speaking to HealthandMe, Dr. Amit Prakash Singh, Consultant - Internal Medicine at the CK Birla Hospital, Delhi, explained the possible underlying causes that can result in hand discoloration. He noted that the condition may be due to:

• Bruising (bleeding under the skin)

This appears as blue, purple, or black patches. It may occur due to minor trauma or sometimes even spontaneously. The use of blood thinners or antiplatelet agents like aspirin can increase the likelihood of bruising. With age, blood vessels become more fragile, making bruising more common.

• Low oxygen or poor circulation

• Swelling (fluid buildup in tissues)

• Infection or inflammation

Dr. Singh advised people "to be concerned if there is sudden swelling in one hand, severe pain or tightness, persistent blue or black discoloration, breathlessness, fever with redness and warmth, or numbness and weakness".

"A purple or blue patch often suggests bruising, blue fingers may indicate circulation or oxygen issues, puffy hands suggest fluid retention, and red, hot swelling points toward infection," the expert said.

However, there is no official medical update on the discoloration in Trump's left hand. Therefore, any claims remain speculative. But it is not the first time that various speculations have been going around about the health of Trump.

In an interview with The Wall Street Journal, in January this year, the US President informed that he takes aspirin doses more than his doctors recommend, and that is the reason for the bruising seen on his right hand. He has repeatedly said that his health is in "excellent" condition.

In the interview, he said, "They say aspirin is good for thinning out the blood, and I don't want thick blood pouring through my heart."

Trump, now 70, was diagnosed with chronic venous insufficiency, a condition that occurs when veins have trouble moving blood back to the heart. He also showed signs of bruising on his hand, which many attributed to frequent handshaking and to the use of aspirin.

Aspirin may still be considered for some people under 60 or 70 who have a higher risk of heart disease, but this decision should be made carefully. Factors like high blood pressure, high cholesterol, diabetes, smoking history, or a strong family history can influence whether aspirin makes sense for an individual.
