In patients with atopic dermatitis (AD), the risk of contact sensitization may be higher as the disrupted skin barrier may increase the penetration of contact allergens. Therefore, it is necessary to screen for concurrent allergic contact dermatitis (ACD) in AD patients. To identify the clinical characteristics and genetic variation in AD patients with concurrent ACD. Read More

Topical drugs containing chloramphenicol and clostridiopeptidase A are frequently used for the treatment of cutaneous ulcers and other necrotic lesions. Chloramphenicol is a bacteriostatic broad-spectrum antibiotic widely used in eye and skin ointments to treat bacterial infections and a well-known cause of allergic contact dermatitis (ACD) (1). Clostridiopeptidase A, also called collagenase 1, is a proteolytic enzyme facilitating the tissue granulation with consequent re-epithelization; it has rarely been reported as cause of ACD (2).

Several antiepileptic drugs (AEDs) are approved by the US Food and Drug Administration for the treatment of bipolar disorder (valproic acid, divalproex, lamotrigine, carbamazepine) and some cutaneous neuropathic pain syndromes (carbamazepine, gabapentin, pregabalin). The AEDs may be effective in the management of (1) chronic pruritus, including pruritus due systemic disease, including uremia, neuropathic pain, neuropathic pruritus, and complex cutaneous sensory syndromes, especially where central nervous system (CNS) sensitization plays a role; (2) management of emotional dysregulation and the resultant repetitive self-excoriation or other cutaneous self-injury in patients who repetitively stimulate or manipulate their integument to regulate emotions (prurigo nodularis, lichen simplex chronicus, skin picking disorder, trichotillomania); (3) management of dermatologic clinical manifestations associated with autonomic nervous system activation (hyperhidrosis, urticaria, flushing; these often occur in conjunction with psychiatric disorders with prominent autonomic activation and dysregulation, eg, social anxiety disorder, posttraumatic stress disorder); and (4) when certain anticonvulsants have a direct therapeutic effect (eg, in psoriasis); currently the use of AEDs for such cases is largely experimental. Gabapentin (dosage range 300-3600 mg daily) is the most widely studied AED mood stabilizer in dermatology and is especially effective in situations where CNS sensitization is a mediating factor.

Autoimmune progesterone dermatitis (APD) is rare autoimmune response to endogenous progesterone or to earlier exposure to exogenous progesterone (1). Skin lesions typically occur due to increases in progesterone during the luteal phase of the menstrual cycle (2). A-31-year-old mother of two children presented to our Department with a 5-year history of pruritic and painful erythematosus macules, papules, and patches on her neck, pectoral region, and face, which appeared 2-3 days before the onset of menses and gradually resolved 7-10 days later (Figure 1).

Human, dog, and cat fleas, as well as bedbugs, feed by biting their victims, causing acute prurigo, which is aggravated in sensitized victims (papular urticaria). The lesions appear in the classic "breakfast, lunch, and dinner" pattern. There are two main explanations: the parasites "map" the skin area in search of the best places to bite, and their removal when victim scratches, and then reattach to the skin. Read More

Prurigo pigmentosa is a unique cutaneous inflammatory disorder characterized by a sudden onset of pruritic and erythematous macules, urticarial papules, and plaques that may coalesce to form a reticulated pattern. Lesions typically heal within weeks leaving a reticulated and mottled postinflammatory hyperpigmentation.

Photo-contact dermatitis (PCD) describes the adverse cutaneous reaction that occurs in some patients as a result of simultaneous exposure to a contactant and to light. PCD can be subdivided into photo-allergic and photo-irritant dermatitis depending on whether the contactant respectively invokes an allergic or irritant reaction. Photo-irritant reactions are commonly caused by plants, psoralens, and medications taken internally, whereas photo-allergic reactions are commonly caused by sunscreens and topical nonsteroidal anti-inflammatory medications.

Chronic pruritus, or itch lasting greater than 6 weeks, is an increasingly common and debilitating medical problem. Recent studies have unveiled previously unrecognized neuroimmune axes whereby inflammatory cytokines act directly on the nervous system to promote itch. Thus, the emergence of newer targeted biologic therapies has generated the possibility of novel treatment strategies for chronic itch disorders. Read More

Prurigo nodularis occurs with chronic pruritus and the presence of single to multiple symmetrically distributed, hyperkeratotic, and intensively itching nodules. Diverse dermatologic, systemic, neurologic, or psychiatric conditions can lead to prurigo nodularis.
