Contracted foal syndrome associated with multiple malformations in two foals.

This journal article looks into contracted foal syndrome, a rare but frequently reported congenital anomaly in horses, by studying two foals with multiple malformations. It presents the radiological and necroscopical findings from the foals, suggesting a connection among these anomalies and exposure to insecticides during the early stage of pregnancy.

What is Contracted Foal Syndrome?

• Contracted Foal Syndrome is a congenital condition in horses, characterized by a contraction of the joints of the forelimbs and/or hindlimbs.
• This condition is occasionally accompanied by malformations in the vertebral column, such as scoliosis or torticollis, and cranial deformity.
• Despite being rare, it is one of the most commonly reported congenital anomalies in horses.

Research Assessment and Findings

• The research centers around the medical examination of two foals suffering from multiple malformations related to the syndrome.
• In both foals, skeletal abnormalities and fenestration of the abdominal cavity were observed.
• Beyond these common findings, each foal exhibited unique complications. One suffered from an interventricular septal defect, while the other showed signs of unilateral hydronephrosis and partial hydroureter.
• These findings were collected through both radiological (imaging-based) and necroscopical (post-mortem) examination.

Suggested Reasons for Malformation

• Although the study didn’t make a definitive conclusion as to the cause of these malformations, it did offer a potential contributing factor.
• The research suggested that the use of insecticides during the pregnancies of the foals’ mothers, specifically within the second month, might be associated with the development of these anomalies.
• The conclusion was deduced from the timing of the insecticide exposure and the developmental problems, although no definite causality was established in this report.
