Managing the Adverse Effects of Radiation Therapy - Article

ABSTRACT: Nearly two thirds of patients with cancer will undergo radiation therapy as part of their treatment plan. Given the increased use of radiation therapy and the growing number of cancer survivors, family physicians will increasingly care for patients experiencing adverse effects of radiation. Selective serotonin reuptake inhibitors have been shown to significantly improve symptoms of depression in patients undergoing chemotherapy, although they have little effect on cancer-related fatigue. Radiation dermatitis is treated with topical steroids and emollient creams. Skin washing with a mild, unscented soap is acceptable. Cardiovascular disease is a well-established adverse effect in patients receiving radiation therapy, although there are no consensus recommendations for cardiovascular screening in this population. Radiation pneumonitis is treated with oral prednisone and pentoxifylline. Radiation esophagitis is treated with dietary modification, proton pump inhibitors, promotility agents, and viscous lidocaine. Radiation-induced emesis is ameliorated with 5-hydroxytryptamine3 receptor antagonists and steroids. Symptomatic treatments for chronic radiation cystitis include anticholinergic agents and phenazopyridine. Sexual dysfunction from radiation therapy includes erectile dysfunction and vaginal stenosis, which are treated with phosphodiesterase type 5 inhibitors and vaginal dilators, respectively.


Topical Psoriasis Therapy - Article

ABSTRACT: Psoriasis is a common dermatosis, affecting from 1 to 3 percent of the population. Until recently, the mainstays of topical therapy have been corticosteroids, tars, anthralins and keratolytics. Recently, however, vitamin D analogs, a new anthralin preparation and topical retinoids have expanded physicians' therapeutic armamentarium. These new topical therapies offer increased hope and convenience to the large patient population with psoriasis.


Topical Therapy for Acne - Article

ABSTRACT: Acne is a common problem in adolescents and young adults. The disorder is caused by abnormal desquamation of follicular epithelium that results in obstruction of the pilosebaceous canal. This obstruction leads to the formation of comedones, which can become inflamed because of overgrowth of Propionibacterium acnes. Topical retinoids such as tretinoin or adapalene are effective in many patients with comedonal acne. Patients with inflammatory lesions benefit from treatment with benzoyl peroxide, azelaic acid or topical antibiotics. Frequently, the use of comedonal and antibacterial agents is required.


Treatment of Psoriasis: An Algorithm-Based Approach for Primary Care Physicians - Article

ABSTRACT: Psoriasis is characterized by red, thickened plaques with a silvery scale. The lesions vary in size and degree of inflammation. Psoriasis is categorized as localized or generalized, based on the severity of the disease and its overall impact on the patient's quality of life and well-being. Patient education about the disease and the treatment options is important. Medical treatment for localized psoriasis begins with a combination of topical corticosteroids and coal tar or calcipotriene. For lesions that are difficult to control with initial therapy, anthralin or tazarotene may be tried. The primary goal of therapy is to maintain control of the lesions. Cure is seldom achieved. If control becomes difficult or if psoriasis is generalized, the patient may benefit from phototherapy, systemic therapy and referral to a physician who specializes in the treatment of psoriasis.


Use of Systemic Agents in the Treatment of Acne Vulgaris - Article

ABSTRACT: Effective treatment of acne vulgaris can prevent emotional and physical scarring. Therapy varies according to the severity of the disease. Topical medication is generally adequate in clearing comedonal acne, while inflammatory acne usually requires the addition of oral medication. Systemic antibiotics are used most frequently and can be highly effective. Newer formulations of combined oral contraceptives are also helpful in modulating sebum production in the female patient. Severe nodulocystic acne that does not respond to topical retinoids and systemic antibiotics may be treated with isotretinoin. However, the side effect profile of this medication is extensive, and physicians should be well-versed in its potential adverse effects.

Atopic Dermatitis: An Overview - Article

ABSTRACT: Atopic dermatitis, also known as atopic eczema, is a chronic pruritic skin condition affecting approximately 17.8 million persons in the United States. It can lead to significant morbidity. A simplified version of the U.K. Working Party’s Diagnostic Criteria can help make the diagnosis. Asking about the presence and frequency of symptoms can allow physicians to grade the severity of the disease and response to treatment. Management consists of relieving symptoms and lengthening time between flare-ups. Regular, liberal use of emollients is recommended. The primary pharmacologic treatment is topical corticosteroids. Twice-daily or more frequent application has not been shown to be more effective than once-daily application. A maintenance regimen of topical corticosteroids may reduce relapse rates in patients who have recurrent moderate to severe atopic dermatitis. Pimecrolimus and tacrolimus are calcineurin inhibitors that are recommended as second-line treatment for persons with moderate to severe atopic dermatitis and who are at risk of atrophy from topical corticosteroids. Although the U.S. Food and Drug Administration has issued a boxed warning about a possible link between these medications and skin malignancies and lymphoma, studies have not demonstrated a clear link. Topical and oral antibiotics may be used to treat secondary bacterial infections, but are not effective in preventing atopic dermatitis flare-ups. The effectiveness of alternative therapies, such as Chinese herbal preparations, homeopathy, hypnotherapy/biofeedback, and massage therapy, has not been established.
