Utilization and rationale for the implementation of total body (digital) photography as an adjunct screening measure for melanoma.

The primary objective of our study was to update the prevalence of total body photography (TBP) utilization and the rationale for its implementation as an adjunctive screening measure by academic dermatologists across the USA, and investigate the emergence of total body digital photography (TBDP). Our secondary objective was to further examine how TBP/TBDP is being incorporated into the dermatology screening examination in academic pigmented lesion clinics. A questionnaire was mailed to 113 dermatology departments across the USA. About 43% (49/113) of surveyed departments responded. TBP was used by 67% (33/49) of the respondents. Of these respondents, 33% (11/33) used TBDP alone, 33% (11/33) used TBDP in combination with nondigitally based TBP, and 33% (11/33) used nondigital TBP with print photos. The three most frequently cited reasons for the use of full-body baseline photographs were that they reduced patient anxiety, led to fewer biopsies, and helped to find melanoma early in the curable stage. Respondents who did not use full body baseline photographs cited logistical constraints as the number one reason, followed by perceived lack of utility. In conclusion, our study shows that there is a significant number of academic dermatologists using TBP/TBDP. However, this study also shows that there are conflicting beliefs among academic dermatologists concerning the efficacy of TBP/TBDP. At this point with a documented growing trend in utilization of TBP, more studies are needed to evaluate the efficacy of this screening adjunct to diagnose melanoma early and positively impact survival because of early diagnosis.

Leishmania tropica-induced cutaneous and presumptive concomitant viscerotropic leishmaniasis with prolonged incubation.

BACKGROUND: Leishmaniasis includes a spectrum of diseases caused by protozoan parasites belonging to the genus Leishmania. The disease is traditionally classified into visceral, cutaneous, or mucocutaneous leishmaniasis, depending on clinical characteristics as well as the species involved. Leishmania tropica is one of the causative agents of cutaneous leishmaniasis, with a typical incubation period of weeks to months. Observation We describe a 17-year-old Afghani girl who had lived in the United States for 4 years and who presented with a 6-month history of pretibial ulcerations, 9.1-kg weight loss, abdominal pain, splenomegaly, and extreme fatigue. Histopathologic examination and culture with isoenzyme electrophoresis speciation of her skin lesions confirmed the presence of L tropica. In addition, results of serum laboratory and serological studies were highly suggestive of concomitant visceral involvement. The patient was treated with a 28-day course of intravenous pentavalent antimonial compound sodium stibogluconate with complete resolution of her systemic signs and symptoms and improvement of her pretibial ulcerations. CONCLUSIONS: This is an exceptional case in that our patient presented with disease after an incubation period of years rather than the more typical weeks to months. In addition, this patient had confirmed cutaneous involvement, as well as strong evidence of viscerotropic disease caused by L tropica, a species that characteristically displays dermotropism, not viscerotropism.
