Magdalene de Koker
Magdalena de Koker accepts a posthumous degree on behalf of her late son, Mervin Hershel van Wyk.

A grieving mother brought tears to the eyes of almost everyone present during a graduation ceremony at the University of the Free State (UFS) on Thursday 20 April, when she took to the stage to accept her late son’s posthumously awarded master’s degree.

The usually festive and jovial graduation spirit inside the Callie Human Centre at the University of the Free State’s Bloemfontein Campus turned sombre in a matter of seconds as Magdalena de Koker ascended the stage to receive her son Mervin Hershel van Wyk’s degree. The Faculty of Theology and Religion student had been on track to receive a Master of Theology degree with a specialisation in Church History and Polity, but passed away before his graduation ceremony. The posthumous degree awarding honoured Van Wyk’s memory and acknowledged his family’s support throughout his academic journey.

“My emotions are conflicted,” De Koker said. “I feel a sense of pride for my son’s accomplishments, and eagerly anticipated celebrating his graduation. However, the profound loss of my son has left me devastated. Instead of being a spectator, cheering him on from the audience, I now find myself standing in his place on stage, wearing unfamiliar shoes, unsure where the toe or heel lies.” 

His legacy lives on

Before closing the ceremony Professor Bonang Mohale, Chancellor of the UFS, said he cried because this degree had to be conferred posthumously. 

“This is sad, tragic, and regrettable,” Prof Mohale said. “We all pray and hope that our children will bury us. Mama, we pray that you get peace by acknowledging the current trauma and pain, so that there can be some acceptance in order to start the process of healing. And with that process of healing comes forgiveness. The wonderful thing about forgiveness is that it allows more healing. May the good Jehovah be with the family and the whole clan. When we pray, we say ‘Thy will be done’. Thank you, in the wake of your pain, for making the time to be with this greater family of Kovsies.” 

Dr Eugene Fortein, Senior Lecturer in Church History and Polity, said his late student was an inspiration to many. “He firmly believed that God cared about the suffering of the impoverished and oppressed, and that justice would be served to those often overlooked. These convictions fuelled his involvement in politics, unafraid to use his Christian beliefs to advocate for change through protests. His trial sermon last year from Amos 5 – ‘But let justice roll on like a river, righteousness like a never-failing stream’ – embodied his unwavering conviction that justice and righteousness were integral to his faith.” 

Van Wyk’s passing is huge a loss for his family, friends, and the UFS and South African academic communities. His dedication and commitment to his studies serve as an inspiration to all those who knew him. The UFS community mourns the loss of a talented student and scholar, but his legacy will continue to live on through his contributions to the field of theology.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
