Notalgia Paresthetica

This patient presented to me with this pigmented itchy patch over the right infra scapular region. He had a neurological disorder with paresthesia extending to right finger tips. There is a report of successful treatment of this condition with Botulinum Toxin Type A. [Arch Dermatol. 2007; 143(8):980-982.]

About Me

As a Dermatologist and Informatician my research mainly involves application of bioinformatics techniques and tools in dermatological conditions. However my research interests are varied and I have publications in areas ranging from artificial intelligence, sequence analysis, systems biology, ontology development, microarray analysis, immunology, computational biology and clinical dermatology. I am also interested in eHealth, Health Informatics and Health Policy.
