Identification of the genetic determinants responsible for retinal degeneration in families of Mexican descent.

Purpose: To investigate the clinical characteristics and genetic basis of inherited retinal degeneration (IRD) in six unrelated pedigrees from Mexico.

Pediatric anogenital warts: a 7-year review of children referred to a tertiary-care hospital in Montreal, Canada.

The objectives of this study were to delineate the clinical characteristics of a hospital-referred pediatric population infected with anogenital warts and to investigate the possible relationships between human papillomavirus types and the identified clinical characteristics. Over a 7-year period, 72 patients under the age of 12 years were seen at our dermatology clinic for anogenital warts, corresponding to a prevalence of 1.7/1000 in our patient population.
