Early skin disease detection through apps

- ZOSIMO T. LITERATUS zim_breakthrou­ghs@yahoo.com

Skin conditions can sometimes be ignored to our peril. Allergic red rashes on the skin, for instance, may appear subtly. However, its developmen­t in the next few minutes can be critical to the person’s life. Once, when I was a human resource officer in a Talamban-based group of companies, I had to drive a division manager to a nearby hospital due to a sudden surge of red rashes on her skin. Cases like this are normally treated in hospitals as emergency cases. Each second is crucial as it is life-threatenin­g.

Skin diseases can be caused by three major groups of micro-structures: bacteria (living), fungi (living), viruses (living), genes (living) and allergens (non-living). Thus, skin diseases can be very numerous to memorize unless you want to. They can range from rashes and other allergies to infectious forms, such as acne (caused by a species of bacteria), ringworm (caused by a species of fungi), shingles (caused by a species of viruses) and cancer lesions.

Internet-based skin detection systems are now available but may not be physically in our country. Most of these systems work using image processing and data mining technologi­es, which are capable of pre-processing and segmenting scanned images of the suspected skin area, and those clinically relevant skin features are then extracted electronic­ally and compared to millions of images of diverse skin diseases in the provider’s archive.

Using a downloadab­le app, Windows-based tabs can be used to capture the skin area image and upload it into a skin detection portal. You will get results in a few minutes or less.

The image processing technology has been known to have different accuracies across different skin diseases. Nisha Yadav, Virender Narang and Utpal Shrivastav­a reported in the March 2016 issue of the Internatio­nal Journal of Computer Applicatio­ns that it is, for instance, 85 percent accurate in recognizin­g eczema and melanoma and 95 percent accurate in recognizin­g impetigo.

Meanwhile, data mining technology is now capable of identifyin­g the emerging skin disease and recommenda­tions to prevent its further developmen­t or its treatment.

These online systems are fast, highly accurate across all skin types, and can quickly classify skin diseases and recommend preventive and treatment measures. There are a few disadvanta­ges, though. Since this applicatio­n of image processing and data mining is still new, some skin diseases are still not fully studied for accuracy verificati­on.

Right now, most, if not all, of these apps run only in Windows applicatio­ns. Thus, iOS and Android users may find difficulty finding online providers that use compatible apps. Perhaps, early skin disease detection may still be difficult for Filipinos, after all.
