Median mental sinus in twins.
Sinus on the chin can be the result of a chronic apical abscess due to pulp necrosis of a mandibular anterior tooth. The tooth is usually asymptomatic, and a dental cause is therefore not apparent to the patient or the unsuspecting clinician. Not infrequently, the patient may seek treatment from a dermatologist or general surgeon instead of a dentist. Excision and repair of the fistula may be c...
متن کاملThe incidence of twins in cerebral palsy and mental retardation.
There is evidence that there is a higher incidence of mental retardation and of cerebral palsy among children born from a multiple pregnancy than among singletons.

The corresponding figure in Shyh-...

We conducted the Adult Attachment Interview (AAI) on 33 pairs of monozygotic (MZ) female twins reared together as an initial exploration of causal influences on mental representations of attachment. As predicted by attachment theory, we obser...
متن کاملMental rotation in female fraternal twins: Evidence for intra-uterine hormone transfer?

In animals it has been shown that a female fetus located between two male ones is exposed to higher levels of testosterone. It is still unclear whether intra-uterine hormone transfer exists in humans. Therefore, the influence of an intra-uterine presence of...
