“…DG histologic sectioning, ex vivo, has been found to enhance yields of histopathological investigations. 7,8 DG surgical procedures, in vivo, have been reported for incisional biopsies, 9,10 excisional biopsy, 11 nail ablation 12 and in Mohs surgeries. [13][14][15][16] However, these studies were conducted in specialist settings and might not be applicable to primary care.…”

INTRODUCTION No research has been found regarding outcomes of dermoscope-guided surgical procedures in primary care. AIM To establish whether outcomes of dermoscope-guided procedures performed in primary care settings differ from outcomes for similar procedures, performed without the use of a dermoscope. METHODS A retrospective case-control study design was used. All records of dermoscope-guided procedures performed over a 6-month period were retrieved. For each study procedure, the record of the most recent control procedure without dermoscopy guidance performed on a sex-and-age matched patient was retrieved from before we began performing dermoscope-guided procedures. Primary outcomes were: local inflammation and infections within 2 weeks’ post procedure; relapse in 6 months; and obvious scars in 6 months. Pain affecting activities of daily living in the first week after the procedure was the secondary outcome. RESULTS Records of 39 dermoscope-guided procedures and 39 control procedures were retrieved. No significant difference in local inflammation and infections in 2 weeks was found; relapse in 6 months after the study procedures was significantly lower for dermoscope-guided than control procedures (risk ratio (RR): 0.22; 95% confidence interval (CI): 0.05–0.95), and there were fewer obvious scars for dermoscope-guided procedures than control procedures (RR: 0.52; 95% CI: 0.32–0.83), with the number of small lesions (<4 mm) leaving scars in study procedures particularly less than that for control procedures (RR: 0.30; 95% CI: 0.13–0.67). There was no difference in the secondary outcome of pain affecting activities of daily living in the first week following the procedure. CONCLUSION In primary care, dermoscope-guided procedures achieved better outcomes than similar procedures without dermoscope guidance. Performing dermoscope-guided procedures in primary care might lower medical costs.

“…When compared with traumatic onycholysis, in onychomycosis the onycholytic area has a jagged proximal border instead of a linear one. Directed to the proximal nail fold, sharp longitudinal indentations are called spikes, which are the reason for the jagged appearance [ 7 – 9 , 11 , 14 , 20 ]. These structures correspond to onset of fungal invasion and are not detected in traumatic onycholysis [ 20 ].…”

“…Dermoscopy appears to be a rapid and useful tool in the diagnosis of onychomycosis. It allows prompt and nonprocedural assessment of the entire nail unit compared to mycological examinations [ 4 , 7 – 20 ].…”

IntroductionOver the years, clinical studies have provided new knowledge about the dermoscopic features of the diseases of cutaneous annexes. It seems that dermoscopy has opened a new morphological dimension in the diagnosis and management of hair disorders and onychopathies.AimTo identify and describe dermoscopic features of onychomycosis.Material and methodsA total of 81 consecutive patients with onychomycosis (55 men and 26 women) were prospectively enrolled in the present study. For each patient, all fingernails and toenails were evaluated in clinical and dermoscopic examinations. Mycological tests were performed by potassium hydroxide (KOH) preparation. Mann-Whitney U and χ2 tests were used for the statistical analysis, with a significance threshold of p < 0.05.ResultsDermoscopic examination of the patients’ nails revealed the following: jagged proximal edge with spikes of the onycholytic area (51.9%), longitudinal streaks and patches (44.4%), subungual hyperkeratosis (27.2%), brown-black pigmentation (9.9%) and leukonychia (1.2%). Jagged proximal edge, subungual hyperkeratosis and leukonychia were positively associated with the onychomycosis type.ConclusionsOnychomycosis accounts for up to 50% of all consultations for onychopathies. Fast and effective diagnostic approaches are needed in everyday clinical practice. Dermoscopy can provide immediate and accurate information in the diagnosis of onychomycosis. We suggest that dermoscopy should be taken as a first step toward the diagnosis of onychomycosis.

“…Other less commonly observed findings include blackish dots and globules, melanonychia due to non-dermatophytic mold, matte homogenous color of detached nail plate, and dryness and scaling of adjacent skin. Nail plate dermoscopy has also been suggested to identify the ideal location for localized abrasion to obtain adequate samples for mycological examination (Bet et al 2015). • Prognosis and treatment: Its prognosis is good if treatment is initiated early.…”

Onychoscopy is becoming more and more frequently utilized for the diagnosis of nail disorders. It allows visualization of varying details of nails that can be diagnostic of several diseases, in particular periungual and subungual warts and onychomycosis. The onychoscopy criteria for majority of the inflammatory and infective nail disorders are evolving at a rapid pace. Distinctive dermoscopic signs that are exclusive to distal subungual onychomycosis and to traumatic onycholysis have also been described and allow a differential diagnosis from psoriasis. It has now become very essential for all the clinicians to learn the technique of
