Ophthalmic manifestations of multiple endocrine neoplasia, type three.

We report the case of a patient with multiple endocrine neoplasia type three, which was first diagnosed by members of the department of Ophthalmology. He was found to have multiple mucosal neuromata and medullary thyroid carcinoma. The ocular components of this syndrome include visible corneal nerves, conjunctival neuromas, thickened lids, anterior displacement of the cilia and a "dry eye" syndrome. The major systemic components are medullary thyroid carcinoma and pheochromocytoma. It is important that the Ophthalmologist recognize the ophthalmic manifestations of this syndrome so that early diagnosis and treatment may be possible.

Lumbosacral transitional vertebra and thoracic limb malformations in a Chihuahua puppy.

A three-month-old, male Chihuahua puppy with congenital absence of the distal 40% of the right thoracic limb was examined. The limb ended as a short, rounded, skin-covered stump. Radiography revealed a 40% shortened humerus tapered to a blunt end without its distal extremity. Dissection of the left thoracic limb identified luxation of the elbow joint and absence of the fourth digital pad. Alizarin-red staining and clearing demonstrated syndactylous fourth and fifth digits in the left thoracic limb and an anomalous eighth lumbar vertebra. This additional vertebra was unilaterally sacralized and constituted a lumbosacral transitional vertebra.
