Dr E W Price, the discoverer of podoconiosis.

A straightforward biography of Dr E W Price, the discoverer of podoconiosis, a medical missionary who was also the first to elucidate plantar ulcers in leprosy.

Lepra: enfermedad milenaria y actual / Leprosy: an ancient and present-day disease

El desconocimiento de la lepra es común en la población general al igual que entre los médicos y el personal de la salud. Se cree que esta enfermedad ya no existe; tal vez su imagen bíblica y milenaria refuerce la idea de su eliminación. Sin embargo, la lepra continúa siendo un problema de salud pública en varios países; entre los más afectados están India y Brasil. Después del inicio de la poliquimioterapia (PQT) en la novena década del siglo XX la prevalencia de la lepra disminuyó considerablemente pero no ocurrió lo mismo con la incidencia, lo que se atribuye al poco impacto de dicho tratamiento sobre el control de la transmisión y a la existencia de un reservorio aún no identificado con exactitud. Los convivientes de los leprosos tienen alto riesgo de sufrir la enfermedad en cualquier momento de la vida, pero hasta ahora no se ha podido determinar cuáles convivientes infectados desarrollarán la enfermedad. En Colombia se informan de 400 a 550 casos de lepra cada año, lo cual sugiere que la transmisión del Mycobacterium leprae continúa a pesar de que el país está considerado en la fase de poseliminación. Este artículo presenta una revisión histórica de la lepra desde los primeros informes disponibles hasta los avances moleculares más recientes. Incluye cómo ha evolucionado la comprensión de la enfermedad, su caracterización clínica, las medidas de control y saneamiento, el tratamiento y la epidemiología.

Ignorance about leprosy is common both in the general population and among physicians and health personnel. It is believed that this disease no longer exists. Perhaps its image as a biblic and ancient scourge reinforces the idea of its elimination. However, leprosy continues to be a public health problem in several countries; among the most affected are India and Brazil. After multidrug therapy (MDT) started during the ninth decade of the XX century prevalence of leprosy dramatically decreased. Incidence, however, did not follow the same trend, probably because of the low impact of MDT on transmission, and the existence of an as yet unidentified reservoir. Familial contacts of leprosy patients are at high risk of suffering the disease at any moment in their lives. So far it has not been possible to determine which ones of the infected contacts will develop the disease. Between 400 and 550 cases of leprosy are reported every year in Colombia. This fact suggests that transmission of Mycobacterium leprae still occurs despite the country being classified as in the postelimination phase. This article presents a historical review on leprosy from the earliest available reports to the more recent advances in the molecular understanding of the disease and its agent. It includes how the comprehension about it has evolved, its clinical characterization, public health control measures, therapy and epidemiology.

Elephantiasis, elastin, and chronic wound healing: 19th century and contemporary viewpoints relevant to hypotheses concerning lymphedema, leprosy, erysipelas, and psoriasis--review and reflections.

Both wound healing and lymphedema have fibrosis of the skin in common. They also share destruction of elastin by elastases from neutrophils as a significant feature. These are not new observations, and the writings of Unna and Kaposi are recalled. The contemporary observations on elastin by Gerli and his team are discussed in the light of these much earlier opinions.
