Abstract

Patent ductus arteriosus (PDA) is a persistent patency of a vessel normally present in the fetus that connects the pulmonary arterial system to the aorta. The ductus arteriosus fails to close at birth when breathing commences and placental blood circulation is removed. Closure of the ductus arteriosus arises in response to decline pulmonary vascular resistance and increased systemic vascular resistance. This report describes a case of PDA in a two-month-old male lamb with clinical signs of machinery murmur, tachycardia, increase respiratory rate, weakness and ill thrift. Echocardiographic examination and necropsy finding confirmed PDA.

Skeletal abnormalities are most often used to describe defects in the arms or legs that are associated with genes or chromosomes, or that occur due to an event that happens during pregnancy. Spider lamb syndrome (SLS) is a congenital disorder in sheep breeding that is recognized by some deformities in skeletal system especially in the limbs.A dead day-old cross-breed white lamb with deformed limbs was referred to the anatomy hall of the Veterinary Faculty of Shahid Bahonar University of Kerman. In the external examination, the lamb was very skinny and in the facial region, superior brachygnathia with a slight Roman nose were observed. Metacarpal and metatarsal regions were more elongated than that expected. Also Metacarpal and metatarsal bones were as long as the antebrachial and crural regions, respectively. This paper, the first report of this syndrome in Iran, described the anatomic and radiographic features of the skeletal deformities in a day-old dead Kermanian breed lamb.

Abstract
A 5-day-old female Holstein calf was necropsied because of lethargy, recumbency and anorexia.

A 5-day-old female Holstein calf was necropsied because of lethargy, recumbency and anorexia. At necropsy, multiple gross defects were evident in several organs, including unclosed sutures of skull bones, asymmetrical orbits, doming of the skull bones, hydrocephalus, hydranencephaly, cleft palate, brachygnathia, ventricular septal defect, mitral valve dysplasia and rudimentary lungs. On microscopic examination, pulmonary hypoplasia was characterized by reduced number of alveoli, replacement of peri-bronchiolar smooth muscles with connective tissue and small masses of undeveloped cartilage around the small airways. The present report is the first description of the congenital pulmonary hypoplasia accompanied by numerous malformations in Holstein breed.

Congenital anomalies of the great thoracic vessels have been reported in 20% of dogs and cats. In some cases, the vascular ring anomalies remain unrecognized throughout the lifetime of an animal. This report describes a case with an unusual vascular ring anomaly (VRA) that was detected during dissection on a cadaver of an approximately two-year-old male native mixed breed dog. No history of the animal’s life was available. But, good physical condition and age of the animal based on dentition indicated the anomaly was perhaps asymptomatic. Two main branches of the aorta were identified with the initial branch being a bicarotid trunk followed by a bisubclavian trunk. The left subclavian and aberrant right subclavian arteries formed a very short trunk and arose directly from the aortic arch. No dilatation cranial to the esophageal sulcus was found. To the authors' knowledge, our case is the first report of such anomalies perhaps without any clinical signs in a native dog in Iran.

Visceral urate deposition (visceral gout) is a common finding during post-mortem examination of poultry. Rare cases of visceral gout may occur in wild birds. A rare case of visceral urate deposition in a little bittern (Ixobrychus minutus) is reported here. In May 2013, carcass of a little bittern was submitted for necropsy to the Clinic of Poultry Diseases (Faculty of Veterinary Medicine, Razi University) by local authorities of Iran Department of Environment. At necropsy, white chalky deposits were observed on the heart and thoracic air sacs of the bird. To confirm the presence of urates, chalky deposits were collected from pericardium and tested by muerxide test. Heart and kidneys were sampled, preserved in 10% neutral-buffered formalin solution and submitted to laboratory for histopathology. Murexide test was positive for presence of uric acid in chalky deposits collected from pericardium. Light microscopy of affected organs confirmed the condition as visceral urate deposition. To the best of our knowledge, this is the first report on the occurrence of visceral urate deposition in a little bittern.
