Limbal pseudotumor in a Cob Pony

A tumor-like tissue mass of lateral-limbal site in the right eye of a 12-year-old Cob Pony mare was presented for surgical removal. The mass, covering the lateral limbus, bulbar conjunctiva and part of the cornea, was surgically removed, and the corneal defect repaired with a pedicle bulbar conjunctival graft. The mass was inflammatory in nature containing mononuclear cells. No recurrence or complication occurred at 6- and 12-month follow-up examination.

Gastrocystoplasty in pigs and effect of selective antral vagotomy on acid secretion of the reconstructed bladder

INTRODUCTION

The aim of this study was to investigate the outcome of gastrocystoplasty and the effects of selective antral vagotomy (SAV) on the postprandial gastrin secretion from the antrum as well as on the acid secretion from the augmented bladder.

MATERIALS AND METHODS

In this study on 12 male pigs, we applied subtotal cystectomy plus gastric augmentation plus SAV to the study group and the same procedure without SAV to the control group. The animals were followed up for 3 months with respect to feeding, weight, and urine output. The urine pH levels and the gastrin levels of the pigs in the two groups were then followed up and compared.

RESULTS

The use of gastric segments in bladder reconstruction was found to be appropriate in terms of both gastric function and urinary system function. Nevertheless, regarding the effect of SAV, the differences between either the urinary pH levels or the gastrin levels of the pigs in the two groups were statistically significant.

CONCLUSIONS

Although gastric segments in the bladder reconstruction were found to be appropriate in terms of both gastric function and urinary system function, SAV did not prevent postprandial gastrin secretion and the resulting increase of the urine acidity.

Granulomatous conjunctivitis in an ostrich

Ostriches lack meibom glands, but have small lacrimal glands ventral to the lateral canthus, with ductules that open into the inside of the lower eyelid. Chalazion is a chronic granulomatous inflammation of the meibom glands that may develop from blockage of the ductules into the conjunctiva. A 2-year-old female ostrich presented with chronic granulomatous conjunctivitis, with clinical and histopathologic findings similar to chalazion of other species. The granulomatous dacryoadenitic mass was excised and no recurrence occurred at 4 months. This is the first case of chronic granulomatous conjunctivitis reported in the ostrich.
