    Notes: Nanostructured semiconductor metal oxides have played a central role in the gas sensingresearch field, because of their high sensitivity, selectivity and low response time. Among all theprocesses, developed for the synthesis of nanostructured metal oxides, gel combustion seems to bethe most promising route due to low-cost precursors and simplicity of the process. It combineschemical gelation and combustion, involving the formation of a gel from an acqueous solution andan exothermic redox reaction, yielding to very porous and softly agglomerated nanopowders.In this work, nanostructured tin oxide, SnO2, and titanium oxide, TiO2, have been synthesizedthrough gel combustion. Powders showed nanometric particle size and high specific surface area.The so-obtained TiO2 and SnO2 nanopowders have been used as sensitive element of resistive λsensor and ethanol sensor respectively, realized depositing films of nanopowders dispersed in wateronto alumina substrates provided with Pt contacts and heater. TiO2-based sensors showed at hightemperature good response, fast response time, linearity in a wide range of O2 concentration andlong-term stability. SnO2-based sensors have shown high sensitivity to low concentrations ofethanol at moderate temperature

    Notes: Elastosis perforans serpiginosa (EPS) is a rare perforating dermatosis in which elastic fibers extrude from the papillary dermis producing umbilicated papules, characteristically arranged to form arciform or serpiginous patterns on the skin. It can be observed in patients with Down's syndrome, in whom in some cases the disease has been reported to be more widespread and to run a longer course. We present the case of a 20-year-old girl with Down's syndrome, hypothyroidism, acne and hypertrichosis, who had a 2-year history of multiple atrophic lesions with an arciform pattern on the distal extensor portions of both thighs, histologically showing the typical features of EPS.

    Notes: The case of a 70-year-old white man with a 10-year history of penile lichen sclerosus (LS) who developed microinvasive squamous cell carcinoma on LS is described. A high incidence of penile cancer arising on genital LS has recently been observed. The authors stress the importance of an adequate diagnosis and long-term follow-up in patients with penile LS because of the malignant potential of the disease.

    Primary classic Kaposi's sarcoma of the penis: report of a case and review (2003)

    Notes: Kaposi's sarcoma is a vascular tumour of multifocal origin occurring primarily on the extremities. The case of a 45-year-old HIV negative and HHV-8 positive man with an asymptomatic reddish macular lesion on the inner layer of the prepuce is described. Although primary penile Kaposi's sarcoma is a relatively uncommon disorder in HIV negative men, dermatologists and venereologists should consider this possibility when treating non-specific penile lesions. A minimal penile lesion with non-distinctive clinical features may sometimes be the exclusive manifestation of Kaposi's sarcoma, making histologic evaluation necessary to establish the diagnosis.

    Videodermatoscopy enhances the ability to monitor efficacy of scabies treatment and allows optimal timing of drug application (2004)

    Notes: Background  Videodermatoscopy (VD) is a noninvasive diagnostic tool that has recently been advanced as an alternative technique for the diagnosis of scabies, based on studies showing its ability to detect mites in vivo with results comparable to those obtained by traditional skin scraping.Objective  In this study we evaluated a group of patients undergoing topical treatment with a thermosensible foam containing 0.165% pyrethrins and 1.65% piperonyl butoxide to determine whether VD would enhance monitoring of the clinical response to treatment and indicate the optimal timing of drug application.Materials and methods  Twenty patients (12 M, 8 F; age 1–65 years) affected by scabies (diagnosis confirmed by VD), and who were treatment naïve, were included in the study. The foam was applied to the entire body once a day at bedtime for two consecutive days. To detect treatment response, VD evaluation of two targeted skin sites for each patient was performed at baseline and at 12, 24, 36 and 48 h. A video microscope system equipped with a zoom lens that allowed skin observation with incident light at magnifications ranging from × 20 to × 600 was used.Results  In all patients, VD showed active mite migration within burrows at 12 h. At 24 h, there was no evidence of active mite migration, and a majority of patients reported that itching had subsided. At 48 h, the mites were no longer visible in appreciable amounts by VD, and an amorphous material, probably resulting from mite decomposition, was detectable at one end of an empty burrow in the majority of patients. Skin scraping at 48 h, followed by standard microscopic observation, also showed only mite remnants in all patients. None of the 20 patients showed signs of infestation by VD at targeted skin sites at a 2-week post baseline follow-up visit.Conclusions  VD enhances the monitoring of clinical response to treatment and allows optimal timing of drug application. This may be particularly important in minimizing risk of overtreatment, reducing the potential for side-effects, and enhancing patient compliance.

    Changes in Rapid Transport of Phospholipids in the Rat Sciatic Nerve During Axonal Regeneration (1983)

    Notes: Abstract: Axonal transport of phospholipids in normal and regenerating sciatic nerve of the rat was studied. At various intervals after axotomy of the right sciatic nerve in the midthigh region and subsequent perineurial sutures of the transected fascicles, a mixture of 60 μCi [Me-HC]choline and 15 μCi [2-3H]glycerol in the region of the spinal motor neurons of the L5 and L6 segments was injected bilaterally. The amount of radioactive lipid (and in certain cases its distribution in various lipid classes) along the nerve was determined as a function of time. Three days after fascicular suture and 6 h after spinal cord injection of precursors, there was an accumulation of labeled phospholipids and sphingolipids in the transected sciatic nerve in the region immediately proximal to the site of suture. Nine days after, there was a marked increase in the accumulation of radioactivity in the distal segments of the injured nerve, which increased up to 14 days after cutting and disappeared as regeneration proceeded (21–45 days). In all segments of both normal and regenerating nerve fibers, as well as in L5 and L6 spinal cord segments, only phosphatidylcholine and sphingomyelin were labeled with [14C]choline. These results suggest that the regeneration process in a distal segment of a peripheral neuron, following cutting and fascicular repairing by surgical sutures, is sustained in the first 3 weeks by changes in the amount of phospholipids rapidly transported along the axon towards the site of nerve fiber outgrowth.

    Notes: Summary Intraepithelial penile carcinoma (IPC) is an in situ carcinoma of the penis, which can be difficult to diagnose. Current treatments include excisional surgery, Mohs' micrographic surgery, cryotherapy, carbon dioxide laser therapy and topical 5-fluorouracil. We report two cases of men with 12–18 month histories of IPC (Bowen's disease, squamous cell carcinoma in situ) that were previously unsuccessfully treated with antifungals and antibiotics. Treatment with imiquimod 5% cream for 8–10 weeks was effective in both cases with no clinical evidence of relapse at 4 and 6 months. Both patients experienced adverse effects, resulting in temporary discontinuation of treatment.
