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.”

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
