Twenty-five syndactylous Angus cattle, characterized pathologically, were reported from 16 herds in 10 states from 1979 to 1994. Twenty-one (84%) had all 4 legs syndactylous, 3 (12%) had 3 legs syndactylous, and 1 (4%) had 2 legs syndactylous. All syndactylous cattle walked with considerable difficulty. Hooves of aged animals became curled and bent laterally or medially. Affected hooves had the...

we investigate buchbaum and eisenbud's construction of the second symmetric power $s_r(x)$ of a chain complex $x$ of modules over a commutative ring $r$. we state and prove a number of results from the folklore of the subject for which we know of no good direct references. we also provide several explicit computations and examples. we use this construction to prove the following ...

Apert Syndrome is a rare genetic disorder that presents with craniosynostosis, syndactyly and midface retrusion dysostosis as well many other anomalies. an autosomal dominant syndrome equally in males females has occurrence rate of 1 every 65,000.

Ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome (or Hay-Wells syndrome) is a rare congenital malformation. Our first cases were a pair of female monozygotic twins with AEC syndrome at Srinagarind Hospital. In this study, we describe monozygotic female twins concordant for ankyloblephaon, ectodermal dysplasia and helical rim deformities, but discordant for cleft, syndactyly of...

Triphalangeal thumb (TPT), a long, finger-like thumb with three phalanges instead of two, is regarded as a subtype of preaxial polydactyly. It can occur as a sporadic disorder, but is more often seen as a dominant familial trait. We describe four white Dutch families in which triphalangeal thumb has variable expression and is sometimes associated with preaxial extra rays, rudimentary postaxial ...

Two cases of ankyloblepharon filiforme adnatum in siblings are presented. One sib had associated cleft lip and palate, the other had bilateral syndactyly of the second and third toes. Father, paternal grandmother, and great-grandmother all had bilateral syndactyly of the second and third toes. Cases of ankyloblepharon filiforme adnatum reported in the ophthalmic literature are reviewed as are c...

Congenital limb deformities are very rare conditions and the knowledge about etiology, pathogenesis, clinical presentation and treatment is still poor. Moreover, many defects are still not reported in veterinary literature. This report documents clinical and radiographic findings in three dogs with congenital deformity involving the distal extremities. Case 1 was affected with bilateral aphalan...
