[Definition and psychopathology of chronic hand dermatitis]. / Définition et psychopathologie de la dermite chronique des mains.

Psychopathology in patients with DCM is as complex as its clinical forms where the factors are numerous and often intricate. It combines psychophysiological, psychopathological factors, behavioral disorders which can be the cause or the consequence of DCM but also the negative impact on quality of life and the simplest daily activities. DCM affects the quality of life of every patient, regardless of the severity. Women are more affected by the DCM that man older age, male sex, atopy and the existence of a contact sensitization are independent risk factors of severity. Depression may affect up to 10 % of patients, should involve greater attention from dermatologists and general practitioners. Health authorities and all health actors should be aware of interactions between secondary cognitive troubles or inherent to DCM and efforts required in terms of preventive measures. Thus, the presence of psychiatric comorbidity is more common in patients with chronic dermatoses. Today it is considered that the emotional environment, built by the mother - child relationship must be optimal, otherwise the mental stability of body image may be compromised. Diminished self-esteem, affects less well managed and somatic expression of emotional content. Recently, a surprising study showed that most patients with refractory occupational dermatitis were not able to recognize the warning sign of flare or the role of psychological factors in the formation and maintenance of the dermatose. In fact, they rejected their personal responsibility in the occurrence of the new flare. To address this public health problem, health authorities, trainers and caregivers should be aware of the cognitive impact of DCM in these patients and interactions with current means of prevention. The role of obsessive-compulsive washing as part of an anxiety disorder or personality disorder is most likely a contributing or maintaining factor systematically underestimated in the pathogenesis of DCM and in the therapeutic management.

[Hand eczema : disability and impact]. / Eczéma des mains : handicap et impact.

INTRODUCTION: Hand eczema is a dermatological condition that may lead to physical and psychological disability, with psychological impact on social relationships, daily life activities and work. OBJECTIVES: Review of the literature on the impact of eczema of the hands and resulting disabilities. METHODS: Medline and Embase search from 1990 to 2013. RESULTS: Hand eczema is a disabling disease because of its poor prognosis. It has an impact on quality of life, which has been assessed using generic scales (MOS-SF36 and EQ-5D) and generic dermatological scales (DLQI and the Skindex). There are no quality-of-life scales specific to hand eczema. This dermatosis may also have repercussions on work, resulting in absenteeism and at times requiring occupational retraining. Hand eczema has economic repercussions with several factors to be taken into account such as medical consultations, medical expenses, loss of productivity, work leave, changes in job position, compensation, and the need for occupational retraining. CONCLUSION: Management of hand eczema by a dermatologist requires taking into account the importance of the physical and psychological disability and the consequences on social relations, activities of daily life, and work. In this context, measuring quality of life is important in assessing patients'perception of the disease and their experience.

[Skin tests in chronic hand dermatitis]. / Place des tests allergologiques dans l'eczéma chronique des mains.

Chronic hand dermatitis is often multifactorial but allergic causes are frequent and can complicate atopic dermatitis or irritant dermatitis. The management of patients affected by hand dermatitis includes detailed interrogation and a complete examination of the skin. Allergologic tests must be systematically realized if examination is suggestive of contact dermatitis or protein contact dermatitis, if an occupational origin is suspected but also in all patients in which treatment is ineffective. Skin tests include patch tests with the European standard series, specialized or additional series if necessary. Skin tests may also include personal items used by patients on a daily basis. If protein contact dermatitis is suspected skin tests include prick tests. Only complete and definitive eviction of allergens can allow a complete and definitive cure of chronic hand dermatitis.

[Therapeutic patient education in chronic hand dermatitis]. / Éducation thérapeutique du patient dans l'eczéma chronique des mains.

Hand dermatitis (HD) is usually due to a combination of various interacting factors. It involves significant impairment of the quality of life with psychological and socioeconomic impact. A therapeutic education program in HD.was elaborated by 19 health professionals (dermatologists, occupational clinical physicians, nurses, psychologists, environmental medical advisor) with experience in therapeutic education or skills in HD, according to the recommendations of Haute Autorité de Santé. The program includes an individual medical consultation to perform educational diagnostic, two collective workshops and a medical evaluation consult. Two group workshops "the disease, irritant factors and its treatments" and "the experiences and feelings" were elaborated with learning objectives and educative tools. Different scores were proposed to evaluate the program and acquired skills. Therapeutic education is an efficient way to help patients to adopt skin protection measures essential to healing. We propose a guideline of therapeutic education in HD including skills and educative tools and intended for health professionals to serve as working basis.

[Management of chronic hand eczema]. / Prise en charge de l'eczéma chronique des mains.

The management of hand eczema, more readily called chronic hand dermatitis, is complex. This heaviness is related not only to the disease itself by its different clinical forms but also the multiplicity and diversity of etiological factors, triggering / maintaining or aggravating factors. The repeated therapeutic failures are ransom of incorrect information about the disease and its environment, a lack of clarity in the prescription and duration of treatment in general too short. The reference treatment is high potency topical steroids with or without occlusion for 4-8 weeks followed by alitretinoin 30 mg / day for at least 3-6 months with a monthly lipid and liver monitoring and mandatory monthly pregnancy test in women of childbearing. Associated measures and patient education are the cornerstones of successful treatment. Other alternative treatments such as phototherapy, methotrexate, cyclosporin, mycophenolate mofetil etc. can be considered in case of resistance or for clearing followed by topical treatments.
