Atopic dermatitis is a chronic inflammatory skin condition. It has a relapsing course characterized by flare-ups of acute eczema on a background of chronically dry skin. The association of atopic dermatitis (AD) with asthma and allergic rhinitis is referred to as the atopic triad.
Several variants of psoriasis are seen in children, the most prevalent types include plaque, guttate, and psoriatic diaper rash; pustular and erythrodermic psoriasis are less frequently observed. This article discusses genetic susceptibility, and environmental triggers are discussed.
Hand dermatitis (HD) is a common skin disorder affecting individuals of all ages. This article looks into the challenges associated with therapy, side-effects of commonly used treatments, and long-term management plans for HD.
Vulvovaginal diseases commonly are inadequately diagnosed and treated. This article discusses the important role dermatologists play in identifying irregular presentations, recognizing skin problems, and addressing itch, pain, and inflammation.
Genital herpes is a common sexually transmitted infection caused by the herpes simplex virus (HSV). This article discusses an overview of HSV, diagnosis and workup, as well as treatment options for management of genital herpes.
Nanotechnology is a relatively new branch of engineering that is making rapid inroads in medicine and dermatology. This article summarizes some of the recent and anticipated advances in nanotechnology for dermatology. In part II, the author addresses the chief concerns of nanotechnology.
Hand dermatitis (HD) is a common skin disorder affecting individuals of all ages. This article discusses diagnostics, individualizing treatments, lifestyle modifications, and outcomes.
The treatment of recurrent aphthous stomatitis (RAS) still remains nonspecific and is based primarily on empirical data. The goals of therapy include the management of pain and functional impairment by suppressing inflammatory responses.
The Role of the Dermatologist in Identification and Treatment of the Early Stages of Psoriatic Arthritis
Early diagnosis of psoriatic arthritis (PsA) is essential for preventing disease progression and joint destruction. We will review the presentation and temporal relationship of psoriasis and PsA, the diagnosis, classification, and management and the role of the dermatologist.
Biologics are one of the more effective and relatively safe options for long-term control of psoriasis. They have reduced the time needed to clear the signs of chronic disease, and are effective in maintaining a disease-free state for longer durations. Biologics can safely be used with other treatment modalities (i.e., methotrexate, cyclosporine, acitretin and hydroxyurea).
Seborrheic dermatitis is a common cutaneous disorder occurring in at least 3%–5% of the population. We discuss new treatment formulations and protocols.
HPV is a very common sexually transmitted disease that is associated with a number of benign, premalignant, and frankly malignant lesions of the anogenital tract. The majority of HPV infections are asymptomatic and are spontaneously cleared by a predominantly cell-mediated immune response.
Skin conditions are commonly found on the lips. Surrounding skin and mucosal surfaces may be involved, and hair problems may be present. Lesions can be single or multiple. Conditions can be localized or diffuse, with other features found upon physical examination that help to make a diagnosis.
Malassezia are lipophilic yeasts that are normal commensals on the skin surface. There are seven species of these yeasts, which were previously called Pityrosporum. The conditions described in this article are either caused by the Malassezia itself or from some kind of immunological or toxic reaction to the organism.
There are currently no laboratory tests to diagnose rosacea; it remains a clinical diagnosis. The actual pathophysiology and etiology of rosacea also remain unclear; however, quite recently the spectrum of rosacea has been classified and standardized.
Diagnosis of onychomycosis can only be established with a positive culture or observation of fungus in the nail clippings. Consideration should be given to cost and possible complications before starting treatment. Recurrent disease is a problem even after a complete cure.
Lentigo maligna (LM) is a pigmented lesion that occurs most commonly on the sun-exposed skin of the head and neck of an older patient. LM can be difficult to completely remove due to its occasional extensive subclinical extension. The gold standard treatment for LM is margin-controlled excision.
Focal hyperhidrosis of axillae, palms or soles is a frequent, socially debilitating condition, triggered by various emotional stimuli. There are several treatment options such as local application of metal salts or tap water iontophoresis, which provide temporary relief for patients.
The ichthyoses are a heterogeneous group of inherited scaling skin disorders that can also affect other organs. Management should be directed at both the skin and other sites. Skin therapy is not specific at this time, although new products may offer more directed therapy in the future.
Psoriasis is a common dermatosis, affecting children in North America. Many papers have stressed the treatments available for adult psoriasis, but few have dealt with this disorder in children. Topical treatment modalities continue to be the first line therapy for childhood psoriasis.
The role of photodynamic therapy (PDT) in the treatment of in situ neoplasias and tumors of the skin is steadily increasing. Its principles of photodynamic action include an intratumoral enriched photosensitizer and light activation.
Treatment objectives and pharmacoeconomic considerations are important when developing guidelines that are effective and rational. Canadian Acne Treatment Guidelines were last published in 1995. New guidelines were recently developed to incorporate therapeutic advances and data from more recent studies.
Systemic sclerosis is a multisystem disorder with vascular instability as a clinical hallmark. Treatment currently consists of recognition and management of end-organ damage.
Behçet’s disease is an inflammatory disorder of unknown cause. There is often involvement of the gastrointestinal system, the central nervous system and large vessels, which can be life-threatening. As well, ocular lesions can cause blindness. Mucocutaneous symptoms are self-limiting but more frequent.
