American Cutaneous Leishmaniasis (ACL) comprises a broad range of cutaneous manifestations caused by different Leishmania species which may produce severe and chronic sequelae in adults. However, it has been suggested that ACL may show different clinical and epidemiological features in children and adolescents that need to be further elucidated. We evaluated the epidemiological features of ACL in a cohort of pediatric patients from Northcentral Venezuela between years 1997 and 2005. Mean age of patients was 9 years old, with a mean clinical evolution of 3 months. Lesions were located mostly in extremities. Forty patients (93%) were positive by MST, 97.7% by IFAT and 48.8% by smear. MST values tended to be related to patients' age, higher values being recorded in older patients (p=0.153).

Congenital syphilis still represents a significant public health problem worldwide, and particularly in developing countries. Despite years of research on different clinical and immunological features, many physiopathological aspects still lacks of knowledge, one of them the role of immune response against Treponema pallidum by infected mothers on the birth outcomes, e.g. birthweight. In this study we analyzed if the mother VDRL titers were significantly associated with the birthweight of newborns with congenital syphilis. We observed a highly significant association between both variables, finding at the linear regression that with higher mother VDRL titers, the newborn birthweight was lower (p=0.0345). We identified that higher VDRL titers are associated with lower birth weights, although the physiopathological reasons to explain this still remains unclear.
