Congenital erythropoietic porphyria affecting two brothers.

We report two brothers, aged 5 and 2 years, with typical features of congenital erythropoietic porphyria. The elder did not receive medical attention until the age of 2 years, even though his urine had been red almost from birth, and despite severe scarring of the hands and face. The younger brother suffered haemolysis at birth. The uroporphyrinogen III cosynthase (URO IIIS) enzyme activity of red blood cells was 2% and 1.2% in the brothers, and genetic studies showed two different mutations of the URO IIIS gene, C73R and P248Q. The latter is a recently described mutation.

[Treatment of condylomata acuminata using liquid nitrogen].

We treated 105 patients with anogenital warts with cotton swabs soaked in liquid nitrogen. 90.1% of the patients were cured, but recurrences were observed in 19.5%. With this method we obtained better clinical results than those obtained with the cryoprobes system. Good results were obtained when the lesions were accessible for treatment, but neither the time of evolution nor the size influenced the cure.

[Anogenital warts in children].

Fourteen cases of anogenital warts in children are reported. Girls were more frequently affected than boys (9/5). Three children had been infected during birth; two had autoinfection from non-anogenital warts; two girls had apparently been sexually abused. In the remaining 7 cases the origin of the warts was unknown. The authors discuss the epidemiological, therapeutic and social implications of this little known but important paediatric pathology, pointing to the possibility of sexual transmission in cases of "apparently" unknown origin.

[A premature aging syndrome hard to classify].

In order to describe the observation of "premature aging", in a 20 year old woman, the clinical characteristics of other genodermatosis are reviewed, and the question of differential diagnosis and etiopathogenesis is raised concluding that these syndromes would have a continuous clinicopathological spectrum with various possibilities of manifestation.
