    Spin–lattice interaction in colossal magnetoresistance manganites (2000)

    Notes: The metal–insulator transition and underlying spin dynamics in La0.7D0.3MnO3 (D=Ca, Sr) are investigated using optical pump–probe spectroscopy at 1.5 eV. Our measurements, which span the ferromagnetic–paramagnetic transition temperature, reveal that the dynamics of the optically induced spectral weight transfer follow the temperature dependence of the magnetic specific heat. This dependence reflects the intrinsic interdependence between the optical conductivity and magnetism in the manganites allowing for the determination of the spin-lattice coupling magnitude. © 2000 American Institute of Physics.

    Notes: Summary Background There is a limited range of treatments for severe atopic dermatitis (AD). Azathioprine has often been used but there has been no randomized controlled trial of this drug to confirm its efficacy in AD. Objectives To establish or refute the efficacy of azathioprine in severe AD. To investigate the safety and tolerability of azathioprine in this patient population. Methods We performed a double-blind, randomized, placebo-controlled, crossover trial of azathioprine in adult patients with severe AD. Each treatment period was of 3 months' duration. Treatments were azathioprine 2·5 mg kg−1 day−1 and matched placebo. Disease activity was monitored using the SASSAD sign score. In addition, severity of pruritus, sleep disturbance and disruption of work/daytime activity were monitored using visual analogue scales. Adverse events were recorded and haematological and biochemical monitoring was performed. Results Thirty-seven subjects were enrolled, mean age 38 years (range 17–73). Sixteen were withdrawn, 12 during azathioprine treatment and four during placebo treatment. The SASSAD score fell by 26% during treatment with azathioprine vs. 3% on placebo (P 〈 0·01). Pruritus, sleep disturbance and disruption of work/daytime activity all improved significantly on active treatment but not on placebo. The difference in mean improvement between azathioprine and placebo was significant for disruption of work/daytime activity (P 〈 0·02) but not for pruritus or sleep disturbance. Gastrointestinal disturbances were reported by 14 patients during azathioprine treatment and four were withdrawn as a result of severe nausea and vomiting. Leukopenia was observed in two patients and deranged liver enzymes in eight during treatment with azathioprine. Conclusions Azathioprine is an effective and useful drug in severe AD although it is not always well-tolerated. Monitoring of the full blood count and liver enzymes is advisable during treatment.

    Notes: Pityriasis rosea is a relatively common skin disorder. In its typical form it is easily recognizable; however, atypical forms can pose diagnostic problems. We report a 44-year-old woman with an acute onset of a localized eruption on her left breast. The morphology of the rash and the time course were typical of pityriasis rosea. Localized pityriasis rosea is an unusual variant, which has been described previously.

    Liquid nitrogen cryotherapy of common warts: cryo-spray vs. cotton wool bud (2001)

    Notes: Background Viral warts represent a large workload for dermatology departments. Cryotherapy with liquid nitrogen is the most widely used method of treatment by dermatologists and is increasingly used by general practitioners in the U.K. Existing data relating to the response to cryotherapy are virtually all derived from the use of a cotton wool bud as the applicator. There is an increasing trend to use the cryo-spray to freeze warts and it has been assumed that this is equally effective. In view of the workload involved it is important to test this assumption. Objectives This prospective study was undertaken to compare these two methods of liquid nitrogen cryotherapy with regards to cure rate after 3 months of treatment. Methods Patients referred to two hospital dermatology departments with hand or foot warts were allocated to have liquid nitrogen applied with either a cryo-spray or with a cotton wool bud. Using either technique, liquid nitrogen was applied until ice-ball formation had spread from the centre to include a margin of 2 mm around each wart. Treatment was done fortnightly for up to 3 months. Plantar warts were pared and treated with a double freeze–thaw cycle. The endpoint of the study was complete clearance of all warts. Results Three hundred and sixty-three patients were enrolled, mean age 21 years (range 3–75), 188 male and 175 female. The mean duration of the warts was 98 weeks (median 78, range 2–936). The number of warts on the hands and feet varied from one to 80 (mean 5). The treatment groups were comparable with regards to baseline demographics. Two hundred and seven patients were evaluable. Cure rates at 3 months were 47% in the cotton wool bud group and 44% in the cryo-spray group (P = 0·8). Warts that had been present for 6 months or less (n = 31) had a greater chance of clearance (84%) compared with warts that had been present for more than 6 months (39%, n = 176) (P 〈 0·0005). Conclusions Cryotherapy with liquid nitrogen for hand and foot warts in our study was equally effective when applied with a cotton wool bud or by means of a spray.

    Imiquimod: a novel treatment for lentigo maligna (2000)

    Notes: Lentigo maligna is the in situ phase of lentigo maligna melanoma, and if left untreated it may progress to invasive melanoma. It most commonly occurs on the exposed sites of the face and neck of middle-aged or elderly patients. Conventional surgery using a 5–10 mm margin is the recommended treatment; however, lesions can be quite large and surgical removal may involve extensive plastic repair. We report an elderly patient with a large lentigo maligna on the scalp who was reluctant to have surgery. We tried topical imiquimod 5% cream (Aldara®), a local immunomodulator, which has recently become available for the treatment of external genital and perianal warts. Initially used over a test area and then over the whole of the lesion, for a total of 7 months, the imiquimod cream resulted in complete clinical and histological cure. The patient has been followed up for 9 months without evidence of recurrence.
