“Dedicated, consistent hard work, a high standard of work ethics, specialised patient care, and high-quality research outputs.” These were the words used by the Head of the Department of Paediatrics and Child Health at the University of the Free State (UFS), Dr Lizzy Tabane, to describe three of its senior consultants who were recently promoted to associate professor.

The three academics who are making a difference in the lives of hundreds of people on a daily basis, are Profs Ute Hallbauer, David Griessel, and Jan du Plessis.

Drug-resistant tuberculosis and diabetics

Prof Hallbauer, the first female professor in the department, works as a consultant senior paediatrician in the Pelonomi and Universitas hospitals. She has proven herself to be a champion in rendering a comprehensive service in paediatric infectious diseases, including paediatric tuberculosis and the specialised area of paediatric drug-resistant tuberculosis (TB).

According to Dr Tabane, when Prof Hallbauer started working with children with drug-resistant tuberculosis in the province in 2006, she reached a success rate of more than 95% compliance and cure of this disease.

It was good to reap the benefits of improved diagnostics and treatment for this disease, says Prof Hallbauer, who initially did not like the topic of TB. “Once my knowledge improved and I diagnosed and managed some difficult situations, it was amazing to see what there is to learn and how much one can do to help children affected by TB. It is worrying that the disease is still so prevalent among children in South Africa,” she says.

Prof Hallbauer also renders a comprehensive service in paediatric diabetes in the Free State and assists doctors from the Northern Cape with advice. Her work includes contributing to the training of dietetics students, where she focuses on food choices for children with diabetes.

“Children with diabetes have taught me a lot of patience. I have learnt to individualise my approach to each child/parent and to never give up and to teach, re-teach and re-teach. Working with the Department of Dietetics and Nutrition to run a Kids Diabetes Camp every year has been a wonderful experience which has benefited everyone: the children, the students, the teachers,” says Prof Hallbauer.

Developmental paediatrics and autism spectrum conditions

Prof Griessel is currently one of two neurodevelopmental paediatricians in the Free State and Northern Cape area and is playing a key role in raising awareness about autism and autism spectrum disorders, both at national and international level. This led to him being elected as a member of the National Executive Committee of Autism South Africa and the Global Senior Leader Committee representing South Africa at the leading world society for autism research, namely the International Society for Autism Research. He was also one of the founders of the Autism Support Centre at the UFS and recently played a significant role in opening the School for Autism just outside Bloemfontein.

He is a firm believer in the critical importance of early child development to thrive in life. The work he is doing has embedded autism in the broader context of child development and is based on recent work in the basic sciences on childhood brain development.

“I am humbled to have interacted with so many autistic adults, young people, children, and families living with autism, who taught me about the real strengths of diversity and demonstrated the courage to persist in the face of adversity,” says Prof Griessel, who finds pleasure in interaction with children and young adults with autism. “Their emotions and feelings come from a pure place and motivate me to continue to be of service,” he says.

Paediatric oncology and paediatric haematology

One of the youngest paediatricians to be promoted to associate professor in the department is Prof Du Plessis, who has proven himself to be a champion in rendering a comprehensive and multidisciplinary service in the field of paediatric oncology and paediatric haematology, with a particular focus on palliative care.

“I always wanted to work with children and their families, and the holistic approach enticed me. It is a privilege to walk the cancer journey with these children and their families, from diagnosis to sometimes the end of life and thereafter.”

“Children are amazing, they have so much joy and unconditional love, and the oncology children are in a completely different league. Where else would you find children calling you their ‘pappa’ or a 15-year-old black girl telling the whole school ‘I have a white father’. It is such a privilege,” he says.

Prof Du Plessis, who was also rated the best lecturer by the medical students in 2020, says besides his fondness for working with children and their families, he unexpectedly fell in love with student teaching. “It is a huge responsibility, but so rewarding to play a small role in shaping the minds of tomorrow’s doctors. It is amazing to witness them experiencing the light-bulb moments and rekindle a passion for the occupation by just spending time with them and being an example of what it looks and feels like to enjoy your work.”

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
