<p>Imported from text file</p> <p><b>New page</b></p><div>== Indications ==<br /> <br /> * For diagnosis of cutaneous filariases such as onchocerciasis<br /> <br /> == Contraindications ==<br /> <br /> * None<br /> <br /> == Equipment ==<br /> <br /> * Either a needle and scalpel, or a sclerocorneal biopsy punch<br /> <br /> == Procedure ==<br /> <br /> * The biopsy is performed using a sclerocorneal biopsy punch or by elevating a small cone of skin (3 mm in diameter) with a needle and shaving it off with a scalpel. This will result in the removal of around 2 mg of tissue.<br /> * The sites for the skin snip are usually over the iliac crest, the scapula, and the lower extremities. Six snips provide the most diagnostic sensitivity.<br /> * The tissue is then incubated in normal saline at room temperature for 24 hours to allow the microfilariae (larvae) to emerge. The microfilariae can then be seen by microscopy.<br /> <br /> [[File:skin_snip1.jpg|img]]<br /> <br /> [[File:skin_snip2.jpg|img]]<br /> <br /> == Further Reading ==<br /> <br /> * [https://www.cdc.gov/parasites/onchocerciasis/health_professionals/index.html CDC Onchocerciasis]<br /> <br /> [[Category:Infectious diseases]]<br /> [[Category:Procedure]]</div>
