A clinical study for the treatment of onychomycosis patients using a novel ROS producing onychomycosis treatment when compared against 5% amorolfine topical lacquer to reduce the visible size of infected toenails.

BACKGROUND: Onychomycosis affects approximately 5% of the population worldwide without satisfactory treatment options regarding efficacy and safety. The aim of this first in human study was to compare the safety and efficacy of the novel compound Mycosinate® against an approved toenail lacquer containing 5% Amorolfine. DESIGN: A randomized, single-blinded, controlled parallel group study with allocation concealment was carried out. METHODS: Thirty-eight participants either used the novel compound Mycosinate® or an approved toenail lacquer containing 5% Amorolfine for topical application in their own homes. Outcome measures included a) % change in area of clear visible toenail, b) mycological cure rate and c) safety assessments. RESULTS: Statically significant differences for % change in area of clear visible toenail (p<0.05) of 39.8, 40.0 and 70.7 in favour of Mycosinate® were noted at time points 6 weeks, 12 weeks, and 6 months respectively when compared to Amorolfine. No statistically significant differences were noted for mycological cure rates. No adverse events, serious adverse events or deaths occurred for either treatment. CONCLUSION: Mycosinate® is a promising novel topical onychomycosis treatment with high rates of efficacy and excellent safety profile. Further clinical trials are warranted.

Thoracic spinal calcinosis circumscripta causing cord compression in two German shepherd dog littermates.

Two young German shepherd dog littermates had progressive, painless, hindlimb ataxia. In both dogs plain radiography of the vertebral column revealed a solitary mineralised lesion on the dorsal laminae between the dorsal spines of the second and third thoracic vertebrae, and myelography with iopamidol demonstrated cord compression at the level of the lesions. The first dog died 18 hours after the myelography. A dorsal laminectomy performed in the second dog resulted in neurological improvement. A histopathological examination confirmed that both lesions were calcinosis circumscripta. The cause of the death of the first dog was meningitis.
