DefinitionThis section has been translated automatically.
Frequent, chronic, also chronically recurrent, painful, mostly microbial (mainly bacterial) induced inflammation of the paronychium.
EtiopathogenesisThis section has been translated automatically.
The causes of chronic paronychia are multifactorial.
- Mostly irritations caused by lyes, acids, foreign bodies are intiating.
- Often also caused by aggressive nail care with cutting of the cuticle. S.a.u. Unguis incarnatus).
- Overlapping by microbial factors such as yeasts (see Paronychia candidamycetica), staphylococci, Pseudomonas aeruginosa (green colouring of the nail).
- Often also occupational (see below occupational dermatoses)
- It is more common in peripheral circulatory disorders or as a result of drug therapies - e.g. after the use of retinoids and EGFR inhibitors such as cetuximab.

ManifestationThis section has been translated automatically.
It is mainly women who are affected. Predisposing are wet works. See also the special features of Paronychia candidamycetica.
TherapyThis section has been translated automatically.
- Elimination of the predisposing factors (wetness, aggressive manicure)
- Targeted protective measures (wearing gloves, avoiding direct contact with aggressive chemicals)
- In case of chronic recurrent purulent paronychia see acute paronychia below. In this case it is recommended to detect the pathogen.
- Local therapy with antibiotic ointments (e.g. ointments containing gentamycin)
- In the case of extensive findings and/or progression of the inflammation under external therapy, antibiotic systemic therapy after an antibioogram. Initial cephalosporins such as cefuroxime (e.g. Elobact) 2 times/day 500 mg p.o. or gyrase inhibitors such as Ofloxacin (e.g. Tavanic 200 mg/day p.o.).
- Afterwards skin care: Desiccated nail walls should be regularly treated with an O/W emulsion.
