Open clinical study of the efficacy and safety of terbinafine cream 1% in children with tinea corporis and tinea cruris.

BACKGROUND Topical application of antifungal agents is considered the treatment of choice for dermatomycoses. Most of the available drugs are fungistatic, requiring long term treatment to prevent relapses. Terbinafine is a synthetic antifungal agent that, because of its fungicidal action, provides high cure rates and low relapse rates after short periods of treatment. METHODS Ninety-seven children ages 2 to 15 years with a suspected diagnosis of tinea corporis and/or tinea cruris were enrolled in this open trial. After mycologic assessment to confirm diagnosis (culture and direct microscopy) terbinafine 1% cream was applied once daily during 1 week. Clinical and mycologic assessments were made at the baseline visit and on Days 7, 14 and 21. Efficacy assessment was based on 88 children (9 patients excluded by protocol violation). RESULTS Therapy was considered effective in 92.0% (81 of 88) of patients (complete clinical and mycologic cure or mycologic cure with minimum signs and symptoms or clinical improvement, > or = 50%). Tolerability was assessed in 97 patients on an intention-to-treat basis. Adverse reactions were itching 3% (3 of 97), itching associated with erythema exacerbation 1% (1 of 97) and contact dermatitis 1% (1 of 97). CONCLUSION Terbinafine 1% cream appears to be an effective and well-tolerated treatment for tinea corporis and tinea cruris in children.

Study of dermatoses in kidney transplant patients

BACKGROUND The increasing in the number of kidney transplant recipients has favored, more frequently than before, the emergence of dermatoses and warranted their study through subsequent publications. OBJECTIVES to evaluate the frequency of dermatoses in kidney transplant recipients. METHODS kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010. RESULTS 53 patients (28 males and 25 females), aged between 22 and 69 (mean age = 45 years) were evaluated. Most of them came from the cities of Ceilândia, Samambaia and São Sebastião/DF, and had already been transplanted for 5 to 10 years before (37.7%); 62.3% were recipients of living donors and 83% were prednisone-treated. The most prevalent dermatoses were of fungal (45.3%) and viral (39.6%) etiologies. Among the non-melanoma malignant neoplasms, the basal cell carcinoma prevailed (six cases), in spite of the low incidence. Concerning fungal dermatoses, 12 cases of onychomycosis, five of pityriasis versicolor and four of pityrosporum folliculitis were reported. For diagnosis, in most cases (64.2%), laboratory examinations (mycological and histopathological) were performed. CONCLUSION cutaneous manifestations in kidney transplant recipients are generally secondary to immunosuppression. The infectious dermatoses, especially those of fungal origin, are frequently found in kidney transplant recipients and their occurrence increases progressively according to the time elapsed from the transplantation, which makes follow-up important.

Mycetomas: an epidemiological, etiological, clinical, laboratory and therapeutic review

Mycetoma is a chronic suppurative disease of the skin and subcutaneous tissue, characterized by a symptomatic triad: tumor, fistulas and grains. It can be caused by fungi (eumycetoma) and bacteria (actinomycetoma), with similar clinical features. Diagnosis is based on the clinical presentation and identification of the etiological agents in the tissue, by mycological/bacteriological, histopathological and immunohistochemical tests. It is important to specify the fungal or bacterial etiology, because the treatments are different. An approach that involves early diagnosis, the use of systemic antibiotics or antifungal agents, including surgical removal of lesions, is the basis for the treatment of these diseases. In this review, the most commonly used diagnostic methods and treatments will be discussed. Also, we will review the history of the disease through epidemiological and etiological aspects.Mycetoma is a chronic suppurative disease of the skin and subcutaneous tissue, characterized by a symptomatic triad: tumor, fistulas and grains.

Epidemiological profile of elderly patients with non-melanoma skin cancer seen at the dermatology outpatient clinic of a public hospital

Basal cell carcinoma and Squamous cell carcinoma, referred to as non-melanoma skin cancer, are the most common malignancies in humans. Their incidence is increasing worldwide every year. In Brazil, even with the advent of educational campaigns on photoprotection and laws that banned tanning beds, they are the most frequent neoplasias, representing a public health problem recognized by the Ministry of health.

Elastosis perforans serpiginosa, a transepithelial elimination skin disease diagnosed by histopathology: case report

Elastosis perforans serpiginosa is a disease that belongs to the group of perforating dermatoses, in which dermal elastic tissue extrusion occurs through epidermis. It generally affects young male individuals, and is clinically characterized by keratotic papules of verrucous aspect with centrifugal and serpiginous growth. We report the case of a male patient presenting with papular keratotic lesions since the age of 5. Some of the lesions display a central keratotic plug and converge into circular, arciform and serpiginous lesions.
