Intermediate steroid hormone levels in dogs with Alopecia X
Alopecia X remains a skin disease with an unclear pathogenesis. Evaluation of several hormon blood levels have been not very diagnostic in the past. This interesting study compares the interemdiate steroid levels before and during different therapies.

The purpose of the study was to evaluate intermediate adrenal steroid hormones (ISH) in neutered dogs with hair cycle arrest (Alopecia X) during treatment with melatonin, and to see if hair re-growth is associated with sex hormone concentrations within the normal ranges.

Twenty-nine neutered, euthyroid, and normo-cortisolemic dogs were enrolled in the study (23 Pomeranians, three keeshonds, two miniature poodles, and one Siberian husky).

Coat assessment and an ACTH stimulation test were performed pre-treatment and approximately every 4 months for a year post treatment.

Melatonin was administered initially at 3-6 mg, every 12 h. Based on clinical progression, each dog was continued on the current dose of melatonin, given an increased dose of melatonin or changed to mitotane.

Partial to complete hair re-growth occurred in 14/23 Pomeranians, and partial re-growth in 3/3 keeshond and 1/2 poodle dogs. A Siberian husky dog failed to re-grow hair. Fifteen dogs had partial hair re-growth at the first re-evaluation.

Melatonin dosage was increased in eight dogs but only one had improved hair re-growth.

On mitotane treatment, partial to complete hair re-growth was seen in 4/6 dogs and no re-growth in 2/6 dogs.

No significant decrease in sex hormone concentrations were seen during melatonin or mitotane treatment.

Concentrations of ISH in dogs with hair re-growth did not differ significantly from pre-treatment values. At the completion of the study, androstenedione, progesterone and 17-hydroxyprogesterone were still above reference ranges in 21, 64 and 36%, respectively, of dogs with partial to complete hair re-growth.

In conclusion, 62% of dogs had partial to complete hair re-growth. However, not all dogs with hair re-growth had concentrations of ISH within the normal range.

SMALL ANIMAL PRACTICE

Detection of venous air embolism via computed tomography
Venous air embolism can be hard to diagnose or to prove in small animals and it seems to be more common than previously thought. This new retrospective investigation describes the prevalence, location and clinical significance of abnormal gas accumulations in dogs and cats detected on computerised tomography images.
