Nail dermoscopy is helpful in the differential diagnosis of nail disorders including onychomycosis and pigmented and nonpigmented nail tumors. We report two cases of onychomatricoma with concurrent onychomycosis of the same digit. In both cases, dermoscopy of the nail plate exhibited features of onychomatricoma, whereas dermoscopy of the distal free edge revealed features of onychomycosis. It i...

BACKGROUND Ingrown toe nail is common problem presenting to the surgeon. Partial Nail avulsion only results in recurrence of the ingrown toe nail. The aim of this study was too see the effect of phenolization in preventing recurrence after partial nail avulsion. METHODS This was a randomized controlled trial carried out at Department of Surgery, Pakistan Institute of Medical Sciences, Islamab...

Ingrown toenail is a common problem resulting from various etiologies including improperly trimmed nails, hyperhidrosis, and poorly fitting shoes. Patients commonly present with pain in the affected nail but with progression, drainage, infection, and difficulty walking occur. Excision of the lateral nail plate combined with lateral matricectomy is thought to provide the best chance for eradicat...

Green nail syndrome (chromonychia) is a nail disorder characterized by onycholysis and green-black discoloration of the nail bed. This condition is often associated with chronic paronychia. Pseudomonas aeruginosa is the most commonly identified organism in cultures from the affected area. Despite the various treatment options available, removal of the nail is still necessary in many cases. A 35...

BACKGROUND Nail bed injuries account for the majority of paediatric hand trauma cases. Despite their frequency, controversy remains regarding their treatment. The accepted teaching is to remove the fingernail, repair the underlying nail bed with fine sutures and replace the nail under the nail fold. A recent study by Miranda et al. (Plast Reconst Surg. 129(2):394e-396e, 2012) suggests that repl...

Knowledge of the anatomy and function of the nail apparatus is essential when performing the physical examination. Inspection may reveal localized nail abnormalities that should be treated, or may provide clues to an underlying systemic disease that requires further workup. Excessive keratinaceous material under the nail bed in a distal and lateral distribution should prompt an evaluation for o...

Hypervelocity impact (HVI), ubiquitous in low Earth orbit with an impacting velocity in excess of 1 km/s, poses an immense threat to the safety of orbiting spacecraft. Upon penetration of the outer shielding layer of a typical two-layer shielding system, the shattered projectile, together with the jetted materials of the outer shielding material, subsequently impinge the inner shielding layer, ...

Stress-corrosion cracking (SCC) tests were conducted in the near-neutral pH standard solution, NS4, and in an actual soil solution, using four-point bending at a high stress ratio and low frequency conditions very similar to those of operational pipelines. Pitting incubation appeared first and then pitting initiated and grew in both solutions although there were many more pits on the specimen t...
