Cloning and characterization of a mouse homologue (mNthl1) of Escherichia coli endonuclease III

The association patterns between maternal anthropometric characteristics (stature, prepregnancy weight, prepregnancy body mass index, pregnancy weight gain) and newborn size (birth weight, length, head circumference) were tested with 10,240 single births taking place between 1985 and 1995 in Vienna, Austria, and 3,452 single births taking place between 1989 and 1995 in Westerstede-Ammerland (Friesland), northern Germany. Maternal size and newborn size differed highly significantly (p < 0.001) between the two genetically and socioeconomically different population groups. Furthermore, the incidence of macrosomia among newborns (birth weight greater than 4000 g) was extraordinarily high (17.9%) in the Frisian group from northern Germany. In both populations taller and heavier women with a higher weight gain during pregnancy gave birth to heavier offspring. Nevertheless, the pregnancy weight gain, which indicates environmental conditions of the mother, had only a minor impact on newborn size compared with stature and prepregnancy weight, which reflect the maternal genetic potential to a higher degree.     

Infantile psoriasis

We report 14 infants younger than 2 years of age with psoriasis vulgaris in order to call attention to the existence of infantile psoriasis. Three of the patients were noted to have psoriasis in the neonatal period; the onset may have been prenatal in one. In 13 of the 14 patients the site of onset was determined by the isomorphic effect (K?bners phenomenon). Although nail pitting is usually said to be infrequent in childhood psoriasis, 11 (79%) of our patients had typical psoriatic nail changes. Psoriasis must be considered in the differential diagnosis of papulosquamous disorders in infants.     

Bone grafts and bone induction substitutes

The use of bone grafts is the basis of all craniofacial surgery. Bone grafts are used to stabilize the open segments, expand the patient's structural boundaries, and fill defects created by trauma or congenital malformations. Bone grafts are harvested from local or distant sites as indicated. Biomaterial implants are used as bone substitutes when it is not possible to use bone grafts.     

Sexual abuse as a factor in anorexia nervosa: evidence from two separate case series

Evidence of a link between reported sexual abuse and specific eating behaviours was considered in 100 anorexic women. The women were assessed as part of case series from two separate clinics. There was a strong association between reported unwanted sexual experiences and purging behaviours (vomiting and/or abusing laxatives). Anorexics who did not purge had lower reported rates of abuse. The pattern and prevalence rate of reported abuse were similar in the two clinics, suggesting that the association was not a product of a specific method of eliciting disclosure. Implications for treatment and possible causal mechanisms behind this relationship are discussed.
