Abstract
Priapism as a complication of scorpionism in children is rare and is categorized as grade II of severity. The pathogenesis is the activation of parasympathetic pathways that stimulate the release of acetylcholine. An 8-year-old boy, a known case of steroid-dependent nephrotic syndrome, presented with a history of persistent penile erection for the previous 12 hours. He had a history of a black scorpion (Heterometrus swammerdami) sting on his right leg 4 days earlier. He was given adequate analgesia, and prazosin was started at 30 µg/kg/dose because of the parasympathetic overactivity. Doppler ultrasonography of the penile shaft showed a bilateral thickened, bulky, and edematous corpus cavernosa and no arterial flow due to venous congestion, suggesting ischemic (low-flow) priapism. Detumescence was not accomplished with saline irrigation and aspiration or with intracorporeal irrigation with phenylephrine. Thus, a distal T-shunt was done. We illustrate an interesting case of scorpion envenomation with delayed ischemic priapism.
期刊介绍:
The American Journal of Tropical Medicine and Hygiene, established in 1921, is published monthly by the American Society of Tropical Medicine and Hygiene. It is among the top-ranked tropical medicine journals in the world publishing original scientific articles and the latest science covering new research with an emphasis on population, clinical and laboratory science and the application of technology in the fields of tropical medicine, parasitology, immunology, infectious diseases, epidemiology, basic and molecular biology, virology and international medicine.
The Journal publishes unsolicited peer-reviewed manuscripts, review articles, short reports, images in Clinical Tropical Medicine, case studies, reports on the efficacy of new drugs and methods of treatment, prevention and control methodologies,new testing methods and equipment, book reports and Letters to the Editor. Topics range from applied epidemiology in such relevant areas as AIDS to the molecular biology of vaccine development.
The Journal is of interest to epidemiologists, parasitologists, virologists, clinicians, entomologists and public health officials who are concerned with health issues of the tropics, developing nations and emerging infectious diseases. Major granting institutions including philanthropic and governmental institutions active in the public health field, and medical and scientific libraries throughout the world purchase the Journal.
Two or more supplements to the Journal on topics of special interest are published annually. These supplements represent comprehensive and multidisciplinary discussions of issues of concern to tropical disease specialists and health issues of developing countries
