Implants give 30-yr-old a jawbone, new teeth

Amazing Feats, Inspiration/ Positive News and Features, Science & Technologies

Chennai:

Shakira gets annoyed when she recalls her troubles with traditional dentures for almost five years. They fell out while she talked, made it tough to chew and worse, often choked her.

Shakira, now 30, lost her teeth and a substantial part of her jawbone because of a condition called juvenile aggressive periodontitis.

Dentures were the first choice, but understanding her difficulties dentists soon told her to consider implants -prosthetic teeth fixed to the jawbone with titanium screws.

But that wasn’t easy either because Shakira did not have enough of the upper jawbone to help doctors fix the prosthetic teeth. “Traditionally, we would graft the jawbone using the cheek bone so we could fix the implant and then prosthetic teeth. But that comes with risks because we expose the entire cheek bone.

At times, we abandon the surgery. There is delay in treatment time,” said senior maxillofacial surgeon Dr Gunaseelan Rajan,  medical director of Rajan Dental Hospital.

So, Dr Rajan and his team decided to use modern technology, adopted in many European countries, to simplify the surgery.

A day ahead of the surgery, doctors scanned her jaw and made a virtual stent using specialized software. Technical experts using a special polymer printed out a 3D model of the surgical stent that became a guide to anchor four zygomatic titanium implants on her cheekbone.

“The stent is discarded and the implant will act as the jawbone where a denture can be permanently fixed,” he said.

The five-day process is done under anesthesia but is more precise than the conventional surgery.

“We did not have to open the cheek bone. The procedure has lesser morbidity and is a lot more comfortable for patients as it is customized to their needs,” he said.

Shakira is happy too. The titanium screws in the jawbone secure the prosthetic teeth to the implant, making them feel almost normal.

“They don’t wiggle or slip, as dentures did,” she said, giving a broad happy smile with her new shiny white teeth.
Dr Rajan has done a similar procedure on 63-year-old Muthukrishan, who lost all his teeth due to old age.

“As of now it costs up to 6,000 more to customize these implants. Soon, we will have customized implants completely replacing dentures,” he said.

Meteorologist in Chennai wins prestigious award

Records, All, Science & Technologies, World Opinion

Many meteorological observatories in the State and the country still use mercury-based measuring instruments to make weather observations and predictions.

In a bid to address the challenge of using dangerous metal, B. Amudha, Scientist-D, Regional Meteorological Centre, Chennai, wrote a report assessing the factors preventing many developing countries to switch over to digital devices.

This won her the Prof. Dr. Vilho Vaisala award instituted by World Meteorological Organisation (WMO).

She was the first Indian Meteorological Department official to receive the award for development of instruments and methods of observation in developing countries at a WMO conference in Madrid, Spain in September. The award was instituted in 1986 and carries a medal, diploma and a cash prize.

Ms. Amudha was nominated to the expert team of WMO. “It was decided during an convention that the mercury based devices must be replaced with digital ones by 2020. But, many developing countries did not initiate measures. My task was to submit a report on the status of alternatives to such instruments and assessing the factors limiting the countries from switching over to digital devices,” she said.

Ms. Amudha framed a questionnaire seeking 191 member countries to respond about the status of the use of mercury based instruments.

“Only 28 per cent of the developing countries responded. In Tamil Nadu, we are replacing mercury barometers used to measure atmospheric pressure in a phased manner. We now have digital barometers in 12 of the 18 observatories run by the department across the State. However, 24 part-time observatories are yet to get digital barometers,” she said.

Moreover, the department is still in the process of replacing mercury thermometers used to measure temperature across the country.

“My report was chosen for the award as it was considered useful to address the issue of enabling transition to digital instruments in developing countries and assist in policy decisions,” Ms. Amudha said.

Fest to explore nuances of colours in arts

Arts, Culture & Entertainment

Chennai  :

Is colour just a pigment that is visually fascinating or is it the reflection of the hues of the mind. Do artists introspect about the various symbols that come into play or is it a spontaneous response. It is these nuances that the upcoming three-day festival Bani will explore.

 
The annual festival, curated by renowned Bharatanatyam dancer Alarmel Valli, looks at the idea of colours  through the prism of the arts. Dance being a visual form, the use of colour is assumed feels the Padma Bhushan recipient.

“Colour is woven into the warp and weft of all art forms. There are different expressions, idioms and perceptions of it and different responses to it. It is widely used instinctively and deliberately, in an abstract as well as literal sense, yet it is often taken for granted. As an artist not many have the time to reflect and articulate these thoughts and so it was a good theme to deal with,” says Valli for whom the theme came together quite spontaneously as the subject has been there on her mind. The dancer for her is like a painter who fills the outline of the song using the body as medium, while the space is the canvas.

Through conversations, music and dance performances artists will be intrinsically bringing out the importance of colour during the festival which begins on October 14.

Bringing together, vocalists, filmmakers and dancers, the festival looks at use of colour in different artistic medias and challenges the audience to find their own meaning.

While singer T M Krishna and documentary filmmaker Arun Khopkar  will set the tone of the festival with talks about interpreting and delineating the concept of colour, Carnatic vocalist Sanjay Subramanian, and Kathak exponent Kumudini Lakhia will be performing and subtly establish the concept using their respective repertoire.

Known for her ability to turn traditional grammar of dance into a deeply personal poetry, Valli has taken on the role of the curator for the past four years. “I like this process of exploring and taking an objective view of the creative process,” says Valli who feels that the metaphor of colour has helped her interpret lyrics and shades of characters.

The interaction on the first day will be at Amethyst Cafe and the performances will be at Kalakshetra.

Leading dermatologist and cosmetologist G.R. Ratnavel was declared brain-dead here on Sunday. He was admitted to the Apollo Hospitals in Tiruchi after he collapsed during a visit to the Rockfort temple here a couple of days ago.

Dr. Ratnavel (50), who headed the Department of Cosmetology at the Government Stanley Medical College, Chennai, was in Tiruchi to attend a conference of dermatologists.

Organ harvest

His family has given its consent to donate his organs, Ratnavel’s father-in-law Maha Krishnan, a senior dermatologist who was also in Tiruchi to attend the same conference, said.

Dr. Ratnavel is credited with having established the first cadaver skin bank at the Stanley Medical College and the Department of Cosmetology at the same institution.

He collapsed while worshipping at the Uchi Pillaiyar shrine atop the Rockfort on Friday morning. He was carried by a few people down and taken in an autorickshaw to a nearby private hospital. He was then shifted to Apollo Hospitals in Tiruchi as he was also a consultant with the hospital in Chennai.

Hospital sources said he was brought in an unconscious state and had suffered intracranial haemorrhage. Having got the consent of the family to retrieve the vital organs, the process of harvest of lung, kidneys, heart, cornea and skin would be done at the Apollo Hospitals here late on Sunday evening, sources said.

Barring the lungs and skin which would be sent to Fortis Malar Hospital at Chennai and Stanley Medical College respectively, the other organs would be sent to few private hospitals in Tiruchi, the sources added.

The post-mortem is expected to be done at the Government Hospital in Tiruchi on Monday. The funeral will take place at Chennai, his family circles said.

Dr. Ratnavel has trained many cosmetic surgeons, said Tiruchi-based senior dermatologist N. Balasubramanian.

Doctors at Government Stanley Medical College were shocked and grieved over the brain death of Dr. Ratnavel, who was the head of the cosmetology department and had served in the hospital for over a decade.

“It was Dr. Ratnavel who developed the cosmetology department — there is no other such department in any government hospital here,” said hospital dean Ponnambalam Namasivayam.

Cadaver skin bank

Dr. Ratnavel spearheaded the setting up of a cadaver skin bank at the hospital, the first of its kind in the government health system in the State. The skin bank, opened in August, stores harvested donor skin that can then be used on individuals as a temporary skin covering cases of burns or acute skin failure as a dressing.

“We have lost a very good colleague,” said V. Anandan, head of the dermatology department, who was with Dr. Ratnavel at the conference in Tiruchi. “He has done so much for the institution. This will be a huge loss to the hospital,” said K. Kannan, head of the cardiology department.

Eminent personalities drawn from various fields showered rich encomiums on one of the country’s well known legal luminaries and former Attorney-General of India K. Parasaran, who turned 90, at a function held here where a book was released in his honour.

Participating in the event, Madras High Court Chief Justice Sanjay Kishan Kaul said, “We are living in troubled times. The process of evolution is on, which must take care to preserve our heritage and yet advance ours as a modern society. Eminence, scholastic ability and honesty of purpose above all has to be the hallmark of both a judge and a lawyer. Shri. Parasaran epitomises all these qualities. He can provide guidance and light to the younger members of the Bar and even to the Bench.”

The book Law & Dharma: A tribute to the Pitamaha of the Indian Bar was authored by three students of SASTRA University and was released in honour of Mr. Parasaran. Chief Justice Kaul released the book and the first copy was received by legal education expert and Chancellor of Central University in Chhattisgarh, N.R. Madhava Menon.

Mr. Menon said Mr. Parasaran was a combination of professionalism with humaneness and simplicity with spirituality.

Noted political commentator S. Gurumurthy, who is also research professor of Legal Anthropology at SASTRA University, recalled an anecdote of how Mr. Parasaran chose to withdraw from appearing for the Central government in 1980s when it refused to honour the orders of the courts in a particular case.

Mr. Parasaran, too, recalled several incidents in his life and in the life of his advocate father, and exhorted the need to remain conscious of dharma while taking decisions. Noting that capitation fee in educational institutions was an issue concerning the students, he said parents felt helpless while the government said it had no funds and there the dharma was lacking.
