Abstract

Scabies is a contagious skin disease due to infestation of Sarcoptes scabiei var. hominis (S. scabiei). Skin scraping microscopic examination is a standard diagnostic procedure, which is still considered as a “gold standard” to confirm the diagnosis. This method is invasive, time consuming with risks associated procedure. Videomicrosc1ope, a non medical digital microscope that can be used to visualize burrow, mites and eggs of S. scabiei. The reliability of videomicroscope to detect mites has not been studied. This study is to determine reliability of videomicroscope and skin scraping microscopic examination in detection of S. scabiei in presumptive scabies patients.This is a diagnostic test study which was conducted from August to October 2017 at the Orphanage Subulussalam, Orphanage Al-Wiam, Lembaga Wanita Peduli Sriwijaya, Lembaga Pendidikan dan Sosial Pemuda Bersatu and Lembaga Perlindungan Anak Kota Palembang. A total of 139 presumptive scabies patients who met the inclusion and exclusion criteria were recruited by consecutive sampling. All subjects were examined with blinded method using videomicroscope and skin scraping microscopic examination by researcher and other examiner. S. scabiei mites that was detected by skin scraping examination was 49,6% of all subject study. Sensitivity and specificity of videomicroscope examination compared to skin scraping microscopic examination were 89,8% and 82,9%. (PPV 83,8%; NPV 89,2%; positive likelihood ratio 4,57; negative likelihood ratio 0,16; accuracy 86,3%, AUC 0,864). Videomicroscope showed high sensitivity and specificity, which was useful as a rapid alternative diagnostic method to detect S. scabiei in high risk population.
