Green nail syndrome (GNS) is the most common bacterial infection of the nail unit. OUR PATHOLOGY SERVICES | PHYSICIAN RESOURCES | INSTRUCTIONAL VIDEOS | ORDER LAB SUPPLIES | FIND AN ACCOUNT MANAGER Green nail syndrome (GNS) is the most common bacterial infection of the nail unit. Both the upper and lower extremities may be affected in GNS, but is uncommonly reported as a primary cause of onychodystrophy. The causative organism, Pseudomonas aeruginosa, is a gramnegative bacteria which is ubiquitous in nature favoring warm and moist environments with reservoirs in soil, water, plants and animals. Infection of the nail [...]

By Steven Goldstein, DPM; Basem Halaka, DPM; David Vance, DPM; Jason Weslosky, DPM There are multiple tests that can be performed to evaluate for the presence of fungi History The patient is a 62 year old male with a 2 year history of thickened, elongated, and yellow discolored nails of the hallux bilateral. The nails appear dystrophic with evidence of subungual debris. The patient does not admit to any significant trauma to the nails but does admit to uncomfortable rubbing of the bilateral hallux nails in his shoes. The patient does not have any other contributing medical history. [...]

DNA-based Onychomycosis Detection Correlates Better to Histopathology than does Fungal Culture

2020-09-16T13:35:20-04:00

Onychomycosis is a prevalent disease of the nail. Traditional methods for diagnosis include direct microscopy with potassium hydroxide (KOH microscopy) and fungal culture. OUR PATHOLOGY SERVICES | PHYSICIAN RESOURCES | INSTRUCTIONAL VIDEOS | ORDER LAB SUPPLIES | FIND AN ACCOUNT MANAGER Traditional methods for diagnosis include direct microscopy with potassium hydroxide (KOH microscopy) and fungal culture. Other techniques using histochemical staining have higher sensitivity, but cannot identify genus or species of the infecting agent. PCR assays are sensitive, specific, and capable of genus and species level identification. We describe a real-time PCR assay for 15 different fungi that [...]
