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.”

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
