The effects of potent topical corticosteroids on adrenocortical function

Atopic Dermatitis in Older Adults: A Review of Treatment Options

Atopic dermatitis (AD) in older adults (elderly AD) has recently emerged as a newly defined subgroup of AD. When selecting treatment options, clinical characteristics of elderly AD and age-specific factors of older patients must be considered. As in other age groups, regular application of moisturizers in combination with topical corticosteroids and calcineurin inhibitors, adjunctive administration of oral antihistamines/anti-allergic drugs, and avoidance of exacerbating factors comprise basic treatments for elderly AD. For moderate-to-severe cases and/or in those with a decreased ability to use topical treatments, powerful anti-inflammatory treatments may become necessary as additional treatment options. While low-dose oral corticosteroids may be useful for cases of elderly AD, careful attention should be paid to adverse effects. Oral cyclosporine (ciclosporin) is less commonly used due to the increased risk of malignancy and organ toxicity in older patients with AD. Narrow-band ultraviolet B phototherapy may also be useful for older patients, although the necessity of frequent hospital visits for irradiation therapy may become a burden of disease for such patients. As a biologic, dupilumab therapy markedly improves skin lesions and itch in older patients with AD, with a rapid response and non-serious adverse effects. Nevertheless, injection pain, expensive medical care, and regular follow-up every 2 weeks are disadvantages of dupilumab therapy. Therefore, clinicians must prioritize individualized treatment options that will reduce the burden of disease for cases of elderly AD.

Psoriasis and psychiatry: an update

Psychosocial factors are important in the onset and/or exacerbation of psoriasis in 40%-80% of cases. Yet psoriasis has received little attention in the recent psychiatric literature. A subgroup of psoriatics appear to be "stress reactors" and these patients may have a better long-term prognosis. Identification of such patients early in the course of treatment and incorporation of specific psychosocial interventions in their overall treatment regimen may improve the course of illness. Psoriasis has also been associated with suicide and an increased prevalence of alcoholism. The disturbances in body image perception and the effect of psoriasis on interpersonal, social, and occupational functioning can further contribute to the overall morbidity, especially if psoriasis first occurs during a developmentally critical period like adolescence. Certain biochemical and physiologic correlates of psoriasis of interest to the psychiatrist such as exacerbation of psoriasis with lithium therapy and increased cutaneous blood flow are discussed. Finally, some practical guidelines are provided for psychosocial interventions in psoriasis.
