13개월령의 중성화하지 않은 암컷 미니어처 슈나우저 개가 귓바퀴의 소양감, 통증 및 상처치유의 지연을 주증으로 내원하였다. 환자의 혈청 성장호르몬 농도가 참고범위 이하로 측정되었으며 자일라진 자극검사를 통해 뇌하수체왜소증으로 진단되었다. 보호자가 원하지 않아 성장호르몬 및 프로게스틴 치료는 진행하지 않았으며, 탈모의 개선을 목적으로 멜라토닌 투여를 시작하였다. 멜라토닌 투여 이후, 귓바퀴의 탈모가 개선되는 것을 확인할 수 있었다.

A 13-month old, intact female, miniature Schnauzer dog was presented with history of dermatitis, pruritus and pain of ear pinnae with delayed puberty. The basal serum growth hormone level was 0.01 ng/ml, which was much lower than the reference range (1.80-2.00 ng/ml). On the xylazine stimulation test, the dog was no responsive to administration of xylazine. The dog was diagnosed as isolated type pituitary dwarfism. Treatment was aimed to improve alopecia with oral melatonin. After initiation of treatment, alopecia of the ear pinnae has been improved.

문제 정의
Clinical feature of pituitary dwarfism includes growth retardation, endocrinal alopecia, soft and wooly hair, anestrus in female dogs, cryptorchidism in male dogs and mental dullness. This case report describes the therapeutic effectiveness of oral melatonin on the alopecia caused by pituitary dwarfism.
제안 방법
In 2006, there was a study about GH stimulation test using synthetic stretagogue ghrelin. In this study, plasma concentrations of GH, TSH, adrenocorticotropic hormone (ACTH), luteinizing hormone (LH), cortisol and PRL were measured 15 min before and 0, 5, 10, 20, 30, and 45 min after ghrelin injection in 6 German shepherd dogs with pituitary dwarfism and 8 healthy beagle dogs. Mean plasma GH response after ghrelin injection was significantly lower in the dwarf dogs compared with that in the healthy dogs.
대상 데이터
A 13-month old, intact female, miniature Schnauzer was presented to the Chonbuk National University Animal Medical Center with a history of delayed wound healing, pruritus and pain of ear pinnae and delayed puberty (Fig 1).
성능/효과
The therapy with oral melatonin was started on a dose of 3 mg/kg, q24h. After 1 month of the therapy, alopecia of the ear pinnae has shown improved and no adverse effect was observed.
