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.

Many women may come across the term "breast density" following a mammogram, but not all of them fully understand what it implies. The fact that someone has dense breasts does not mean that they have cancer or that they will definitely get it.

On the other hand, greater breast density can be linked to a higher risk of breast cancer and may also make it more difficult to detect certain cancers on a mammogram.

What Is Breast Density?

The breast density is the ratio of fibrous and glandular tissue to fatty tissue in the breast. Dense breast tissue is a normal variation and is especially frequent in younger women. It should be clear that women cannot tell themselves if their breast has dense tissue or not; it has to be assessed using breast imaging, typically a mammogram.

Breast density is usually divided into four types, going from almost all fatty tissue to very dense tissue, and women who have heterogeneously dense or extremely dense breasts are at a greater risk of developing breast cancer than women whose breasts are mainly fatty.

What Do Dense Breasts Indicate?

A major concern is that on a mammogram dense tissue appears white, just as many breast abnormalities—some of which are cancers—do too. This makes it harder for radiologists to spot certain abnormalities. Women need not be alarmed if their mammogram report states that their breasts are dense.

Breast density is just one of the factors to take into account when evaluating the risk of breast cancer; family history, age, past breast conditions, genetic mutations, hormonal factors, reproductive history, and lifestyle must also be considered.

It will depend on a woman's total risk level whether or not further screening is needed. Although mammography is still an important method of screening, in certain individual cases a doctor may suggest extra imaging, for example breast ultrasound or magnetic resonance imaging (MRI). Such tests are not required automatically for every woman who has dense breasts.

What Should Women Do?

Women should also know what is normal for their breasts. If a new lump is detected, there is a persistent change in the shape or size of the breast, the skin becomes dimpled, the nipple turns inwards, there is an unusual discharge from the nipple or there is ongoing discomfort, then it is advisable to have a healthcare professional look at it. Yet the majority of breast changes are not cancerous and symptoms by themselves are not enough to make a diagnosis.

Lifestyle plays a big role in maintaining breast health. One way of reducing the overall risk of breast cancer is to keep a healthy weight, remain physically active, limit alcohol intake, avoid tobacco, eat a well-balanced diet and stick to the recommended screening programmes.

Women must not regard breast density as a diagnosis. The main point is that women should not be afraid of dense breasts but should understand what this means for them. They must talk to their family doctor about their mammography report and their individual risk factors and then follow a screening programme suitable to their risk.

Breast density is therefore a valid reason for having a screening examination, not one for concern. By understanding breast density and talking to a breast specialist, women can make informed choices regarding screening and make sure that any potential abnormalities are assessed as early as possible.

Teachers are unarguably one of the most important influences during the early stages of a person's life. Along with learning and wisdom, teachers can also influence a child's or adolescent's mental health. Thus, they help shape students who are the future of any society or nation. This impactful profession and its contributions are celebrated worldwide, including in India.

The deteriorating mental health condition in students has escalated into a major global public health concern, heavily accelerated by academic pressure, systemic changes, and digital isolation. The World Health Organization (WHO), UNICEF, and Indian governmental bodies like NCERT have shared data that reveals a grim situation: there is a huge gap between the rising psychological distress among youth and the infrastructure available to support them.

The role of teachers in youth mental health is a topic that the study "A Shelter for the Heart: The Impact of Teacher Quality on Students' Mental Health" has thoroughly analyzed. The research, published in the journal Health Economics in 2026, was conducted in China and included 3,529 Grade 7 students, 86 classrooms, and 43 schools throughout the country. The study examines the impact of teacher quality, proxied by teacher experience, on student mental health.

How Do Teachers Protect Students' Mental Health?

According to the study, the role of the head teacher is particularly important to a student's mental well-being. While subject teachers are primarily responsible for learning, the study emphasizes that experienced teachers might do more than improve grades—they may also help protect students' mental health.

The study finds that the more experienced head teachers tended to build stronger teacher–student relationships, communicate more with parents, and create more supportive classroom environments. They were less likely to ignore or isolate struggling students and more likely to try to help them. All in all, the researchers concluded that school environments play an important role in determining adolescents’ mental health.

Mental Health On Location And Gender

The study “A study on mental health of students teacher in relation to their achievement in education psychology” by researchers at Tamil Nadu Teachers Education University, Chennai, found significant differences in mental health based on gender and location, with female and rural student-teachers reporting better mental health than their male and urban counterparts.

Teacher Distress Linked To Student Mental Health

A 2024 study published in BMC Psychology by researchers from McMaster University, the University of Sydney, the University of Johannesburg and the Hospital for Sick Children examined the relationship between teacher distress and student mental health. The researchers analysed data from 23,568 students and 1,478 teachers across 268 schools in Ontario, Canada. The researchers suggested that supporting teachers’ mental health and creating safer school environments could also benefit students’ well-being.

A 2019 study published in the Journal of Affective Disorders by researchers led by Stephen Harding also suggested that better teacher well-being was associated with better student well-being, highlighting the potential importance of supporting teachers’ mental health within schools.

Teachers Day 2026

Teachers’ Day 2026 in India is celebrated on September 5 to honour the contribution of teachers and educators. The day marks the birth anniversary of Dr. Sarvepalli Radhakrishnan, India’s first Vice President and second President, who was a distinguished philosopher, scholar and teacher. Since 1962, his birthday has been observed as Teachers’ Day in India. The occasion recognises teachers’ role in shaping students’ knowledge, character, confidence and well-being, while inspiring future generations to learn, grow and contribute to society.

Deceased organ donation covers our organ needs. In India, we are woefully short of organs such as kidneys and livers in cases of liver and kidney failure that need to be transplanted.

Deceased donation, as the name sounds, is a donation by people who are brain dead, whose family has now accepted and has willingly donated their organs for the benefit of the rest of the world.

Live donation, on the other hand, is a donation by living or emotionally related individuals who want to donate a kidney to a diseased patient. A live donation is usually transplanted immediately. It's done in the same centre, and both are done together, as the harvesting of the organ from the donor and transplantation are done simultaneously.

On the other hand, a deceased organ from a cadaveric donor may be harvested in a different geographical location and may be transported over time and over a lot of distance to another centre.

Deceased donation can be done for organs that cannot be transplanted by live donation, which are so consequential to a human body, such as the heart, lungs, and pancreas. They are very vital and cannot be transplanted from a live patient to another.

In a deceased organ donation, we can even donate tissues such as the cornea, skin, and blood vessels, which are required as a part of donation, as a part of other organ donation transplant programmes or, for example, in giving vision to people who have a white cornea or corneal opacity.

These are a few differences between live and deceased or cadaveric donation.
