Treatment of Nail Fold Hypertrophy by Combining Conservative Techniques.

INTRODUCTION: Hypertrophy of the nail folds is a common condition. It occurs by alteration of shape, partial loss, or absence of the nail, resulting in loss of the nail fold physiological limit. This can also occur by the friction of the nail with the nail fold. Consequently, there is an increase in the volume of the lateral or distal nail fold and a decrease in the space of the nail bed and the nail plate. Management of this onychodystrophy may be conservative or surgical. CASE PRESENTATION: We present a case of distal nail embedding after trauma, submitted to conservative treatment. Combined techniques were required as trichloroacetic acid application, rolled cotton padding maneuver, artificial resin nail technique, and orthesis. After 14 months, good functional and aesthetic results were obtained, with correction of the anatomical shape of the nail unit. CONCLUSION: The conservative techniques for hypertrophy of the nail folds are a useful option with good functional and aesthetic results. The indication must be precise, considering the history of the patient and after discarding bone alterations by image exams. The disadvantage of the method is the long treatment time and constant visits to the doctor's office.

Microneedling with Drug Delivery (Hydroquinone 4% Serum) as an Adjuvant Therapy for Recalcitrant Melasma.

A 42-year-old woman with phototype V, presented a 9-year history of refractory centrofacial melasma to topical bleaching agents and peelings, untreated for the last 90 days. One session of microneedling with 1.5 mm needles was performed with hydroquinone 4% sterile serum drug delivery; after 3 days, modified Kligman's formula (hydroquinone 4% + fluocinolone acetonide 0.01% + tretinoin 0.05%) and broad-spectrum sunscreen SPF 70 were introduced for daily use. After 30 days, a significant improvement was observed in the clinical outcome (Figure 1) and the quality of life of the patient. These parameters were measured using Melasma Area and Severity Index (MASI) scale, with an 82.5% decrease, and Melasma Quality of Life Scale - Brazilian Population (MELASQoL-BP), with a 60% decrease. Dermatoscopic analysis (polarized videodermatoscopy x20) of the glabellar region revealed lighting of the pseudoreticular pigment network, diffuse light to dark brown background, and reduction in vascularity and telangiectasias (Figure 2). At the 5-month follow-up, there had been no relapse. The patient continued to use a broad-spectrum sunscreen along with the topical regiment.
