The association between balanitis xerotica obliterans (BXO) and skin disorders is long established, however, the role of skin phototype and local trauma in its onset has never been investigated in detail. Medical records of all Caucasian children circumcised over a 6-year period were reviewed. The excised skin underwent histological examination for BXO. Children with histological diagnosis of BXO were classified as group A, whereas children without histological diagnosis of BXO were classified as group B. The Fitzpatrick phototype (FT) was obtained in all children performing a personal or family interview with regards to their sunburn and suntan experience. According to their FT, both group A and B patients were divided into two subgroups: FT 1-2, with a higher tendency to sunburn due to their low skin melanin content; and FT 3-4 with a higher tendency to tan due to their higher skin melanin content. Maneuvers of mechanical reduction of the foreskin (MRF) performed at least 5-10 times per month during the year preceding circumcision was also considered. Statistical analysis was performed using univariate and multivariate analysis. A total of 297 patients met the inclusion criteria of our study: 78 patients were classified as group A and 219 as group B. The risk of developing BXO was significantly greater in FT 1-2 patients (n=76) (odd ratio=0.232, 95% confidence interval=0.124-0.435, p<0.0001). Furthermore, those undergoing MRF (n=131) had a significantly higher risk of developing BXO (odds ratio= 5.344, 95% confidence interval=2.860-9.987, p<0.0001). Although the foreskin is not directly exposed to sunlight, this study emphasizes the role of skin phototype on the onset of BXO in circumcised individuals. Moreover, the data produced suggest should the advantages of repeated MRF be weighed against the increased risk of developing BXO, which in turn may increase complication rate of circumcision surgery.

Background: Cancer is one of the most difficult current health challenges, being responsible for millions of deaths yearly. Systemic chemotherapy is the most common therapeutic approach, and the prevailing orientation calls for the administration of the maximum tolerated dose; however, considerable limitations exist including toxicities to healthy tissues and low achievable drug concentrations at tumor sites. Electrochemotherapy (ECT) is a tumor treatment that combines the systemic or local delivery of anticancer drugs with the application of permeabilizing electric pulses. In this article we evaluate the capability of ECT to allow the use of cisplatin despite its high toxicity in a spontaneous feline model of soft tissue sarcoma.Methods: A cohort of sixty-four cats with incompletely excised sarcomas were treated with cisplatin-based adjuvant ECT and monitored for side effects. Their response was compared to that of fourteen cats treated with surgery alone.Results: The toxicities were minimal and mostly treated symptomatically. ECT resulted in increased local control (median not reached at the time of writing) with a mean time to recurrence of 666 days versus 180 of controls.Conclusions: We conclude that ECT is a safe and efficacious therapy for solid tumors; its use may be considered as part of strategies for the reintroduction of drugs with a narrow therapeutic index in the clinical protocols. © 2011 Spugnini et al; licensee BioMed Central Ltd.

Dermoscopy (dermatoscopy, epiluminescence microscopy) is a non-invasive diagnostic technique for the in vivo observation of pigmented skin lesions (PSLs), allowing a better visualization of surface and subsurface structures (from the epidermis to the papillary dermis). This diagnostic tool permits the recognition of morphologic structures not visible by the naked eye, thus opening a new dimension in the analysis of the clinical morphologic features of PSLs. In order to reduce the learning-curve of non-expert clinicians and to mitigate problems inherent in the reliability and reproducibility of the diagnostic criteria used in pattern analysis, several indicative methods based on diagnostic algorithms have been introduced in the last few years. Recently, numerous systems designed to provide computer-aided analysis of digital images obtained by dermoscopy have been reported in the literature. The goal of this article is to review these systems, focusing on the most recent approaches based on content-based image retrieval systems (CBIR). © 2010 by the authors; licensee Molecular Diversity Preservation International, Basel, Switzerland.

A 22-year-old Camargue mare was referred for showing signs of discomfort during chewing, building up of food in the mouth, and foul odor from the mouth. On physical examination, the mare presented bilateral pigmented labial masses affecting the upper and lower lips, more in the form of plaques at the mucocutaneous junction as well as multiple perivulvar and perianal lumps. The skin lesions were biopsied for histopathologic examination and the clinical suspect of melanoma was confirmed. The owner elected the lesions to be treated with electrochemotherapy using the drug cisplatin. After two sessions, the nodules were shrunk by 50% and the horse's ability to feed normally was restored: at that time, the owner had the treatment discontinued because of financial issues. The horse is still in partial remission after 1 year from the end of the treatment. Electrochemotherapy can be successfully used to palliate large melanomas in horses. © 2011 Elsevier Inc. Source
