Conjunctival brush cytology from horses
Which cells are observed in conjunctival brush cytology (CBC) from normal horses in comparison with conjunctival structural histology? A very interesting new study.

This study was divided into three parts.

(1) Conjunctival brush smears were collected from 20 healthy horses on both eyes and a differential count on 300 cells was carried out on May Grünwald–Giemsa (MGG) smears.

(2) A similar protocol was used for whole eyes from five horses obtained rapidly after death from a slaughterhouse. The eyes were then assessed for conjunctival histology.

(3) Cytobrush smears were collected from five healthy horses. Smears were examined after MGG or periodic acid Schiff (PAS) staining.

Results: The differential cell count showed a majority of deep and intermediate epithelial cells with very few superficial and goblet cells in both eyes.

A stratified columnar to cuboidal epithelium was observed on nearly the whole surface of the conjunctiva.

A stratified squamous type was observed at the palpebral and bulbar edges.
Areas with highest mucus cell indices were found from the nasal to the temporal edge of the equine inferior conjunctiva in the upper palpebral segment near the fornix and in a part of the nasal fornix.

In MGG smears no mucus cells were identified; however, they were numerous in PAS smears (22.6% ± 11) and were mostly cylindrical cells (42.5% ± 14.4 PAS positive).

Conclusions: Cytobrush smears in the healthy horse are characterized by a majority of polyhedral and cylindrical cells and a few squamous cells. The cylindrical cells may be mucous cells and probably originate from the main stratified columnar to cuboidal epithelium.

SMALL ANIMAL PRACTICE

Sonography vs percutaneous palpation to identify targeted thoracolumbar intervertebral disc spacesmembers
During minimally invasive spinal surgery, correct identification of the affected intervertebral disc space is critical. Percutaneous palpation is commonly used, but results may be unreliable. Fluoroscopy is the gold standard but can be cumbersome and exposes operators to ionizing radiation. Spinal ultrasound has been described in veterinary medicine and could be a feasible alternative. This prospective, methods comparison study mimicked a minimally invasive spinal surgery in 10 canine cadavers and compared the accuracy of ultrasound and percutaneous palpation for thoracolumbar intervertebral disc space identification, using fluoroscopy as the reference standard.
