SUMMARY Pincer nails are a common problem, and various treatments have been reported. However, there is no simple assessment of severity. We designed a curvature index for the nail plate to assess the severity of pincer nail. Measurement of the curvature index was as follows. The apparent width of the nail tip was defined as A, and the traced length of the nail tip was defined as B. The curvatu...

INTRODUCTION The yellow nail syndrome is usually described as the combination of yellow nails with lymphoedema and often with respiratory manifestations such as pleural effusions, chronic sinusitis and bronchiectasis. The syndrome is most often seen in the middle-aged individuals. CASE PRESENTATION We present a 6-year-old girl with yellow nail syndrome having pansinusitis and bronchiectasis. ...

Editor Alterations in the structure and appearance of the nail unit may be seen in association with a variety of dermatological disorders. 1 Because of the limited number of reaction patterns associated with the nail unit, many of the changes that are seen, such as onycholysis, pitting and subungual hyperkeratosis, are not specific. However, certain clinical findings, especially when present in...

DESIGN Open study involving 36 patients with moderate to severe nail psoriasis treated with acitretin. SETTING University-based outpatient dermatology clinic specializing in nail diseases. PATIENTS A total of 27 men and 9 women (mean age, 41 years) with nail psoriasis. INTERVENTION Ther...

Onychophagia is defined as a chronic nail biting behaviour affecting about 20-30% of the general population. However, nail biting seems to be an ignored problem in a daily clinical practice. We have analysed the influence of onychophagia on quality of life (QoL) and stigmatisation level among 339 medical students with and without nail biting. Those with onychophagia demonstrated significantly h...

BACKGROUND The effect of nail polish on pulse oximetry measurements in non-hypoxic subjects has been studied extensively. Some studies found that nail polish decreased pulse-oximetry (S(pO(2))) values, whereas others found no effects from nail polish. OBJECTIVE To determine if nail polish affects S(pO(2)) measurements in mildly hypoxic subjects. METHODS At high altitude, 5 investigators, wh...

Topical therapy of onychomycosis, a fungal infection of nail plate and/or nail bed, offers an attractive alternative to treatment with systemic antifungals. To treat fungal infections locally, antifungal-loaded nail lacquers have been prepared in our laboratory. Franz diffusion cells have been used to investigate drug permeation from such lacquers into and through the nail plate in vitro. Altho...

Synopsis---The flat NAIL of some primates, including man, is unique and is usually formed from one area of the nail fold invagination called the MATRIX. This is deeply placed below two layers of EPIDERMIS and is therefore well protected from injury. Alternative .methods of nail formation more closely resemble the formation of a mammalian claw and may be regressions to a more primitive state. Co...

BACKGROUND Cutaneous T-cell lymphoma (CTCL) encompasses a broad range of lymphoproliferative diseases affecting the skin and can be clinically misleading due to its variable presentation. Nail alterations commonly appear in advanced-stage mycosis fungoides and true Sézary syndrome; however, they may be present in any stage of the disease. Although proper recognition of nail involvement in CTCL ...

BACKGROUND Although nail psoriasis affects a marked proportion of patients with psoriasis and causes significant psychological stress, only few epidemiological data characterizing patients with nail involvement are available. OBJECTIVES To gain robust data on the epidemiology and disease burden of nail psoriasis in Germany. METHODS Two nationwide, noninterventional, cross-sectional studies ...
