A 32-year-old male with febrile ulceronecrotic Mucha-Habermann disease (FUMHD) responsive to methotrexate is reported. This is a severe variant of pityriasis lichenoides et varioliformis acuta characterized by the acute onset of a widespread ulceronecrotic cutaneous eruption together with high fever and systemic involvement. To our knowledge, only 13 patients with FUMHD have been reported to date.

We treated 20 patients who had tinea corporis and/or tinea cruris and 20 patients who had tinea pedis with oral fluconazole. All patients were given a single 150-mg dose of fluconazole upon entry into the study; at that time, and at each follow-up visit, clinical signs and symptoms were evaluated and mycological and laboratory examinations were performed. If clinical and/or mycological cure or significant improvement in a patient's condition was not evident at the 7-day follow-up visit, a second dose of fluconazole (150 mg) was given. A maximum of four doses, one week apart, were given. A long-term evaluation of the efficacy of fluconazole in the treatment of these infections was performed 28-30 days after the last dose was administered to each patient. For the treatment of tinea corporis and/or tinea cruris, 70% of patients required two doses, 20% required three doses, and 10% required four doses. At the long-term follow-up visit the clinical and mycological response rates were determined to be 95% cure and 5% relapse. For the treatment of tinea pedis, 20% of the patients required two doses, 20% required three doses, and 60% required four doses. For these patients, the long-term clinical response rates were 70% cure and 30% improvement; mycological response rates were 75% eradication, 10% persistence of infection, and 15% relapse. This treatment was well tolerated; no adverse effects or clinically significant laboratory abnormalities were reported.

Eco-chemical control based on essential oil mediated plant-insect interactions is an alternative method to the unsystematic use of insecticides, due to advanced structural diversity and allelopathic potential of essential oils. In this sense, present work was aimed at qualitative and quantitative investigation of chemical composition and the evaluation of insecticidal activities of Ruta graveolens essential oil and its major constituents against Sitophilus zeamais and Corcyra cephalonica in stored maize. Fresh leaves were subjected to hydrodistillaton and the chemical composition of oil was studied. Essential oil and its major constituents were then assessed for their allelopathic activity on test insects. Fifty components were identified, where long chain aliphatic 2-methyl ketones predominated the oil as major constituents. Results revealed strong concentration-, insect species- and time-dependent toxicities, in which oil caused 100 % mortalities at concentrations of 1.52 and 0.46 µL/cm2 against S. zeamais and C. cephalonica respectively after 24 hours of exposure. In aliphatic 2-methyl ketone series, respective congeners having odd and even number of carbon atoms were more effective on S. zeamais and C. cephalonica. These findings provide a scientific basis for the eco-potential of using essential oil of R. graveolens and its major constituents in integrated insect pest management programs.
