Aim. Nail disorders are among the most difficult dermatological disorders depending on the many morphologies they present, which make difficult its etiological diagnosis. The objective of our study is to assess frequency of changes occurring in the ungual (onyxis) and periungual (perionyxis) areas of hands of subjects examined in a qualified dermatological centre in relation to their working activity.
Methods. The study has been conducted with a group of 900 subjects who were monitored for 6 months. On admission, physicians selected only those subjects who presented changes in the ungual and periungual areas of hands. The same subjects have undergone dermatological visit with a specialist. All subjects who were diagnosed with perionyxis–onyxis have undergone fungal tests (microscopic and culture test) through nail curettage.
Results. Among the initial group, 48 subjects (group O) were selected, they only presented changes in the ungual and periungual areas of hands at the time of admission. From group O subjects presenting the main confusing factors were excluded. After this further selection, 29 subjects were diagnosed with perionyxis–onyxis (group P). The fungal test through nail curettage in group P showed that in confectioners only, perionyxis–onyxis was not associated to microbial superinfection.
Conclusion. The collected data show an increased prevalence of perionyxis–onyxis in confectioners compared to the other working categories (such as hairdressers, beauticians and nurserymen). This information should explain the different physiopathologic process which is at the base of the development of that condition.
