Nosicelo Madushana, a third-year medical student at the UFS, was four years old when she sustained third-degree burn wounds on 70% of her body.

With winter fast approaching, healthcare professionals in the Free State are gearing up for an increase in burn injuries during these cold months. Many of these injuries are preventable, and doctors and medical staff believe educating communities about common preventive practices can help keep them safe.

Dr Hilge du Preez, Paediatric Surgeon from the University of the Free State (UFS), says they observe an increase in burn injuries, which can be devastating, causing serious bodily harm, long-term disability, and even death, during the winter months.

“As healthcare professionals, we do all we can to help burn injury patients recover and regain their health and activity. However, as with many other conditions, the best treatment for a burn injury is prevention. Thermal burns are the most common type of burn we see. These are caused by contact with hot substances or fluids, such as flames or boiling water. Children and adults sustain burn injuries in different ways.

“While children can suffer burns from flames, they are more likely to burn themselves by spilling hot liquids or food. We also see cases where children accidentally fall into a tub of hot water that is being prepared for a bath,” says Dr Du Preez.

According to Dr Du Preez, when cooking, it is safer to have pot and pan handles turned inward, rather than outward where children can reach them. Kettle cords and tablecloths should be tucked in and kept out of reach to prevent children from pulling them and spilling hot substances.

 

A turning point

Nosicelo Madushana, a third-year medical student at the UFS, was four years old when she sustained third degree burn wounds on 70% of her body after a large pot of boiling water, fell on her. However, she would only later really understand the impact of this accident on her life.

 “It wasn’t until I was in Grade 3 that I began to understand that I was perceived as different. During an Eskom educational session on the dangers of electricity, the presenter used the analogy of turning into a "chicken roast" when tampering with electric circuits. In that moment, a number of my peers turned, pointed, and laughed, likening me to the example given.

“That experience marked a turning point in my self-awareness and emotional resilience. It shaped me profoundly. I became emotionally guarded, not violent, but verbally defensive. I often felt I had to exist in survival mode rather than being allowed to simply be myself,” Nosicelo recalls.

As a result of these experiences, she explains, she developed a deep-seated need to constantly prove that she belonged in every space she entered. She wanted to ensure that any opportunity or recognition she received was based solely on merit and not influenced by perceptions of her physical appearance or sympathy for her circumstances. It became an unhealthy cycle of overcompensation and striving to validate her presence.

This is demonstrated in her academic achievements as she first did a Bachelor of Sciences in Medical Bioscience degree, followed by a postgraduate diploma in Augment and Virtual Reality (Comp Science) (both at University of the Western Cape). She followed this up with an Honours degree in Anatomical Pathology at Sefako Makgathu Health Sciences University.

 

Apply correct first aid treatment immediately

Dr Du Preez says they also recommend that children should never be left unsupervised around hot substances, whether food or fire. When running a bath for a child, add cold water to the tub first, then hot water to reach the desired temperature. This is safer because, if a child falls into the tub, they will only encounter cold water rather than hot, which could prevent a severe, potentially life-threatening injury.

Adults, on the other hand, explains Dr Du Preez, typically sustain severe burns due to flames, which may result from house fires or accidents involving fire. Paraffin stoves are responsible for a significant number of house fires in South Africa, and healthcare professionals strongly advise against their use.

In the era of load-shedding, people need to be mindful of safe practices when using candles, says Dr Du Preez. Candles should never be left unattended and should always be placed in a container that covers the flame. This helps prevent the risk of a candle setting a room on fire if it falls over.

“If someone suffers a burn injury, correct first aid treatment should be applied immediately. Remove any clothing and jewellery from the affected area, and ensure any burning debris is removed. Cool the burn by running it under lukewarm tap water for 10-15 minutes. Cover the wound with a clean, damp cloth and seek medical attention. Do not apply “home remedies” such as toothpaste, raw egg, or shoe polish, as these can impair healing and increase the risk of infection and scarring.

“In the event of a fire, remember to ‘stop, drop, and roll’ to extinguish any flames. Remove burning clothes and debris, cover the person with a clean towel, and seek urgent medical care.”

 

Being burned victim is her normal

Nosicelo, whose passion lies in research and the fight against cancer, being a burn victim is her normal. She has no memory or photographic evidence of herself without burns. “What I dislike the most is the empathetic gaze, the unsolicited pity, the assumption that I am a victim in constant need of help. I am not a tragic story. I am a woman who is brave, resilient, beautiful, and forging her own path.

“My life is not defined by the incident, but by the choices I make and the legacy I intend to leave. I am a three-time graduate, and I will not stop until I attain the prestigious FCPath(SA) qualification (the Fellowship of the College of Pathologists of South Africa, a recognised postgraduate qualification in pathology for medical practitioners in South Africa.) My journey is one of strength, not sorrow. I am committed to being a part of the global effort to eliminate this disease. Until that day comes, I dedicate myself to being a voice for cancer education, prevention, and early detection, empowering individuals with knowledge that can save lives.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
