Ultrasound detection of cosmic filler injection of lips in camel beauty pageants: first report in veterinary medicine.

This study was carried out in Saudi Arabia during the events of the 4th King Abdulaziz Camel Festival, Saudi Arabia. It was designed to describe the most frequent locations of injected cosmetic fillers in the head region as well as the ultrasound features of the injected material. Apparently healthy camels (Camelus dromedarius) (n = 11,626) were thoroughly examined for injection of cosmetic fillers in the head region. In parallel, 30 non-injected camels were used as controls. The lips of camels suspected of having been injected with fillers were subjected to high-resolution ultrasound examination. Of the 11,626 camels, 58 were found to have been injected with cosmetic fillers, 45 in the upper lip and 13 in both the upper and lower lip. None of the injected camels had a history of recent illness. In addition, in all the injected camels, no dermal lip lesions were seen by the naked eye. Swelling of the upper and/or lower lips was visually inspected and palpated by hand in 52 of the camels. Drooping and swinging of the injected lips were observed in all injected camels. Hardness was detected in the tip of the upper lips of 26 of the injected camels and multiple hard nodules were palpated in the injected lips of 44 camels. Swelling of the edges of the upper and lower lips was detected in 41 of the injected camels. Ultrasonographic features of the injected lips are described in detail. Blood samples were collected from both groups. In none of the injected camels did the hemato-biochemical profiles differ significantly than the control group. In conclusion, results clearly indicate the usefulness and convenience of ultrasound as a diagnostic tool to locate the presence of injected fillers and to help monitor the extension and complications of the deposits.
