Dr Lehlohonolo Makhakhe is from the Department of Dermatology at the University of the Free State (UFS).

A senior lecturer and specialist in the Department of Dermatology at the University of the Free State (UFS) has published the very first comprehensive African atlas on skin diseases commonly seen in the African setting. 
The African Atlas, synopsis and practical guide to clinical dermatology also contains more than 1 000 high-resolution images and is intended for medical and nursing students.

Dr Lehlohonolo Makhakhe, a full-time medical specialist (dermatologist) and the author of the book, says this is the first comprehensive full-colour atlas, with contributions from endocrinologists, haematologists, rheumatologists, psychiatrists and the UFS departments of Pharmacology, Dietetics and Paediatrics.

The project started in 2016, after Dr Makhakhe received formal approval from the UFS Ethics Committee and the provincial Department of Health and it was officially published in July 2020 by African Brilliant Minds Publishers. 

The book will have numerous benefits

Dr Makhakhe was a general practitioner with his own practice before joining the UFS to specialise. He then realised that a comprehensive manual was needed, focusing on common skin conditions in our South African setting. He further realised we lacked such a book which would be very beneficial to doctors and nurses. 

“I decided to write this book to encourage unity among doctors in different fields within medicine, particularly at the UFS, and to help promote the culture of writing and producing quality, well-researched, locally brewed content that is relevant to our setting. 
“I also wanted to play a part in providing de-commodified (affordable) books, in the hope of dispensing knowledge and promoting learning for our medical and nursing students to get sound book knowledge, so that they can better manage skin-related pathology,” added Dr Makhakhe.

He said he also aims to create revenue for the university and advance research projects through this book. It also provides an overview of the management of the conditions included in this user-friendly manual.

Challenges during the compilation of the book 

Dr Makhakhe highlighted the huge costs for the publisher, time management of the different contributors, as well as gaining the trust of the contributors for a concept that has never been done before. He aimed to change perceptions relating to dermatology as a secluded and isolated discipline, but also for the department to be seen as an integral part of the medical discipline. 

According to the author of four books (including this one), the publisher is also in talks with many nursing schools across the country to make the book available to nursing students. 

Dr Makhakhe says this atlas was by far his biggest project to date, as his first three books were short stories. He is currently working on a national project with contributors including Prof Johann Schneider (Head: Anatomical Pathology, Stellenbosch University), Prof Jacqueline Goedhals (Head: Anatomical Pathology, UFS), Prof Nndweleni Bida (Head: Anatomical Pathology, University of Pretoria), Prof Faffa Jordaan (Former head of Dermatology, Stellenbosch University) and Prof Wayne Grayson (renowned pathologist in the private sector), which will also be the first of its kind. 
“In summary, the publications are aimed at building a good name for our university through locally produced, high-quality books that are affordable. Once production costs to the publisher are settled, a sizable portion of future proceeds will then be directed to the university as per endorsement protocols.” he stated further.

Dr Makhakhe thanked the Head of the Free State Department of Health, Dr David Motau, the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, the acting Deputy Director-General of Clinical Services, Dr Marcus Molokomme, and also extended a special word of appreciation to the Head of the School of Clinical Medicine at the UFS, Prof Nathaniel Mofolo, for his assistance and support in making this project a success. He concluded by thanking all the contributors for making time for this historic project. 

The book is now fully endorsed by the UFS and will be offered as part of the curriculum for third- to final-year medical students.

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.
