Itch in the elderly presents a diagnostic and therapeutic challenge. A thorough history, review of systems, and physical examination are critical to determining its cause. Examination of the skin may be misleading. ⋯ The diagnosis of Willan's itch should be reserved for generalized pruritus in the absence of xerosis or other recognizable cause. The pathophysiology of this form of pruritus is poorly understood, but it is likely that age-related changes of the skin, cutaneous nerves, and other parts of the nervous system play a role. Anecdotal and limited data suggest that gabapentin, cutaneous field stimulation, serotonin antagonists, and ultraviolet B phototherapy may attenuate itch in some of these patients.

Hypertrophic and keloidal scars: an approach to polytherapy.
Cryotherapy and intralesional corticosteroids have been used separately or in combination as a treatment for hypertrophic and keloidal scars. The addition of silicone gel to the treatment schedule might be of interest. ⋯ Our study suggests that polytherapy may be an effective tool in the therapy of hypertrophic and keloidal scars.

Abstract The larval stages of the fly Cochliomyia hominivorax are responsible for myiasis, which primarily affects wounds. We report the case of a bed-ridden patient with dementia who developed right nasal myiasis during his stay at Cayenne Hospital. Progression was favorable, but the nasal pyramid was partially destroyed. In zones where this fly is endemic, particular attention should be given to hospitalized patients with wounds and consciousness problems.
