Cytomegalovirus - Article
ABSTRACT: Cytomegalovirus (CMV) is a prevalent viral pathogen. The majority of persons with acute CMV will experience an inapparent infection. Primary CMV infection will cause up to 7 percent of cases of mononucleosis syndrome and will manifest symptoms almost indistinguishable from those of Epstein-Barr virus-induced mononucleosis. CMV, or heterophil-negative mononucleosis, is best diagnosed using a positive IgM serology. Complications of acute CMV infection in immunocompetent persons are rare, except in newborns. The virus usually is spread through close personal contact; transmission risk can be reduced by following simple hygienic and handwashing techniques. Severe illness can occur after reactivation of the latent virus in immunosuppressed persons. The retina is the most common site of CMV-induced pathology in persons with human immunodeficiency virus infection. Advances in the treatment of human immunodeficiency virus infection with highly active antiretroviral therapy (HAART) have decreased the incidence of CMV retinitis but have resulted in a new set of ophthalmologic complications induced by restoration of immune competency and the pro-inflammatory response of the patient to CMV. If HAART restores the patient's CD4 cell count to above 100 to 150 per mm3 (100 to 150 x 10(6) per L), it may preclude lifelong treatment for CMV retinitis.
Noninfectious Penile Lesions - Article
ABSTRACT: Family physicians commonly diagnose and manage penile cutaneous lesions. Noninfectious lesions may be classified as inflammatory and papulosquamous (e.g., psoriasis, lichen sclerosus, angiokeratomas, lichen nitidus, lichen planus), or as neoplastic (e.g., carcinoma in situ, invasive squamous cell carcinoma). The clinical presentation and appearance of the lesions guide the diagnosis. Psoriasis presents as red or salmon-colored plaques with overlying scales, often with systemic lesions. Lichen sclerosus presents as a phimotic, hypopigmented prepuce or glans penis with a cellophane-like texture. Angiokeratomas are typically asymptomatic, well-circumscribed, red or blue papules, whereas lichen nitidus usually produces asymptomatic pinhead-sized, hypopigmented papules. The lesions of lichen planus are pruritic, violaceous, polygonal papules that are typically systemic. Carcinoma in situ should be suspected if the patient has velvety red or keratotic plaques of the glans penis or prepuce, whereas invasive squamous cell carcinoma presents as a painless lump, ulcer, or fungating irregular mass. Some benign lesions, such as psoriasis and lichen planus, can mimic carcinoma in situ or squamous cell carcinoma. Biopsy is indicated if the diagnosis is in doubt or neoplasm cannot be excluded. The management of benign penile lesions usually involves observation or topical corticosteroids; however, neoplastic lesions generally require surgery.
