Background: Fragrances constitute the second most frequent cause of allergic contact dermatitis in Spain.

Objectives: To determine the rate of sensitization to the individual fragrances of fragrance mix (FM) I and FM II for each of the demographic and clinical factors included in the MOAHLFA (male, occupational dermatitis, atopic dermatitis, hand dermatitis, leg dermatitis, facial dermatitis, age) index.

Methods: We conducted a 5-year retrospective study in 23 Spanish centres.

A novel automatic incident detection (AID) method for freeways, based on the use of data provided by Bluetooth sensors and an unsupervised anomaly detection approach, is presented. The two main advantages of the proposed AID system are: (i) the use of Bluetooth sensors offers several practical advantages over inductive loop detectors (ILD), which is one of the preferred sensing technology for traffic flow; and (ii) the unsupervised anomaly detection approach builds a model without the need of incident information. A common problem when designing an AID system is that incident information, i.

Objectives: To analyze trends in the prevalence of contact sensitization to p-phenylenediamine between 2004 and 2014, taking into consideration that the concentration of this product in cosmetics was regulated in 2009. To explore risk factors for contact allergy to p-phenylenediamine.

Material And Methods: Retrospective observational study of patients suspected of having contact dermatitis from allergy to p-phenylenediamine during the years between 2004 and 2015 in 8 tertiary level hospitals.

Background: Fragrance chemicals constitute the second most frequent cause of contact allergy in Spain. There are no data available concerning the individual fragrances that are most frequently involved.

Objectives: To describe the diagnostic contribution provided by specific fragrance series to the results obtained with baseline series fragrance markers by correlating the results of both series.

A novel method to tune a Proportional-Integral (PI) compensator for an integrating plus dead time (IPDT) process, in presence of interval parametric uncertainty, is presented. The design is based on optimization of load disturbance rejection with constraints on the magnitude of the sensitivity and complementary sensitivity functions, that must be satisfied for any element belonging to a set of plants. Instead of solving this problem with a brute force approach (grid the uncertainty set), we prove that this problem can be solved by considering only two plants.

Background: Limonene and linalool are common fragrance terpenes widely used in cosmetic, household and hygiene products. Their primary oxidation products formed after air exposure, the hydroperoxides, have been recognized as important contact haptens.

Objectives: To investigate the prevalence of contact allergy to hydroperoxides of limonene (Lim-OOHs) and hydroperoxides of linalool (Lin-OOHs) in Spain, and to define the optimal concentration for screening in consecutive patients.

Muir-Torre syndrome.

Adv Exp Med Biol

August 2010

Muir-Torre syndrome (MTS) is an autosomal dominant genodermatosis that consists of unusual cutaneous sebaceous neoplasm, with or without kerathoacantomas and one or more low-grade visceral malignancies, with or without colonic polyps, in the absence of other predisposing factors. This chapter presents a review of the principal clinical and genetic findings in this syndrome and discusses its relation with Lynch syndrome.

Article Synopsis
  • - We studied germline changes in CDK4 exon 2, CDKN2A, and MC1R in 89 families with multiple members affected by melanoma and found that 30% carried CDKN2A variants, including three known alleles present in Mediterranean populations.
  • - The prevalence of nonsynonymous MC1R variants was significantly higher (72%) in these Spanish melanoma families compared to the general population (60%).
  • - Our new classification of MC1R variants linked loss of function types to an increased risk of multiple melanoma cases in families, suggesting they play a significant role in melanoma risk in areas with lower incidence rates.

Dimethyl fumarate is a fumaric acid ester. It been used for some years to treat psoriasis and also as a preservative in desiccant sachets in the transport of furniture and footwear. Its irritant properties and sensitizing potential in contact with the skin were recently highlighted when it was implicated as the causative agent in 2 epidemics of severe acute eczema: sofa dermatitis in northern Europe and shoe dermatitis in Spain.

Background: Sebaceous gland tumors are a rare type of neoplasm. In some cases they have been associated with visceral tumors in patients with Muir-Torre syndrome, a hereditary form of nonpolyposis colorectal cancer. The aim of this study was to review the diagnosis and follow-up of a series of patients with sebaceous gland tumors to assess how many met the criteria for Muir-Torre syndrome.

Reticular telangiectatic erythema (RTE) is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We present a patient who developed an erythematous patch over the implantable cardioverter defibrillator site. We discuss the clinical features, histologic findings, and patch testing of this entity.

Background: First, to establish the mutations of the protoporphyrinogen-oxidase (PPOX) gene in four Spanish patients with variegate porphyria (VP). Second, study of carrier status detection in the families, including a four-generation Balearic family. Third, evaluation of the results of carrier detection screening methods.

The adenoid form of squamous cell carcinoma is a neoplasm that is characterized by the fact that it presents a pseudoglandular pattern in the histological study. The biological phenomenon that explains this histological pattern is acantholysis; when the latter is massive, the tumor may even mimic a vascular proliferation, and is known as pseudovascular squamous cell carcinoma. This tumor has the clinical characteristics of a squamous cell carcinoma, but histologically, it may mimic an angiosarcoma.

We present the cases of two patients diagnosed with non-microcytic lung carcinoma who were treated with epothilone, a new chemotherapeutic agent which disrupts microtubule dynamics. The first one developed nail symptoms consisting of painful nails with a hemorrhagic appearance, which developed into significant structural disorders and onycholysis of all of the fingernails. The patient required antibiotic treatment for the associated paronychia and surgical removal of some of the nails.
