Associated Multiple Congenital Malformations in Domestic Animals. Contribution of Four Cases

Abstract

Summary The incidence and significance of the appearance of various associated congenital malformations in a single individual have received poor attention in veterinary medicine. In this article, the malformations exhibited by four animals pertaining to three different animal species are described, and the possible reasons for the association of these anomalies are discussed from the viewpoint of the comparative medicine. All four animals showed two or three malformations constituting unrecognized teratological syndromes, so‐called one‐of‐a‐kind syndromes, which have not previously been described, at least in these particular animal species. A pig was affected by a series of craniofacial anomalies consisting in a first arch syndrome together with an occipito‐parietal meningocele. Another member of the porcine species showed holoprosencephaly with cyclopia, various defects in the left forelimb and an extensive omphalocele. A dicephalic cat with cervical rachischisis and myeloschisis and a dog exhibiting spina bifida, curled tail and atresia ani are also described.

Simental Bir Buzağıda Görülen Çoklu Konjenital Anomaliler

“…Bu olguda ise hareket sistemi, sindirim sistemi ve kardiyovasküler sistem anomalileri birlikte görülmüştür. Sistemlerin anomaliden bu kadar etkilenmesinin sebebi ise literatür-de [24] de belirtilen, "çoklu konjenital anomalilerde vücudun bir kısmında oluşan anomali diğerlerine de öncülük eder" şeklindeki hipotez olarak düşünülmektedir.…”

Surgical correction of bilateral polydactyly in a dromedary camel: a case report

“…Polydactyly is a redundancy of digits distal to the basopodium specific for a species (Barber 1990;Alam et al 2007). Unilateral or bilateral polydactyly has been reported as a single anomaly or in combination with other congenital defects (Camon et al 1990;Talamillo et al 2005). Polydactyly has been reported in humans, horses, cattle, sheep, dogs, cats, llamas and guanaco (Al-Ani et al 1998;Clark et al 2000;Bahr et al 2003;Giofre et al 2004;Fayeye et al 2006;Sakai 2006;Altenbrunner-Martinek et al 2007;Zapata et al 2008).…”

Supernumerary ectopic limbs in Korean indigenous cattle: four case reports

“…Congenital abnormalities may be multiple or may affect single parts of organ systems. Multiple congenital anomalies often occur because the malformation of one part of the body leads directly to the malformation of another part (Camon et al, 1990). These anomalies are associated with genetic factors (transgenes, chromosomes), environmental agents (infections, toxins, fertilization techniques, management) or a combination of factors (Keeler et al, 1981;Rousseaux and Ribble, 1988;Newman et al, 1999).…”
