Objective: To evaluate the usefulness of teledermoscopy as a diagnostic and triage method for suspected skin cancer lesions between Primary Care and Dermatology. To analyse the reduction in the number of referrals and estimate the savings achieved., Material and Methods: Concordance study on a non-randomised case series. Descriptive observational study of teleconsultations sent from two Health Centres (urban and rural) to the reference Dermatology service in Cordoba (Spain) between January 2017 and April 2019. The diagnoses proposed by Primary Care before and after the use of dermatoscopy, and the diagnosis of the Dermatologist, along with other epidemiological variables were collected. Descriptive analysis and concordance study were performed., Results: A total of 395 teleconsultations were made. The coefficient of agreement between the diagnoses of both specialists without using dermoscopy was 0.486. Using this technique the concordance was 0.641. A reduction in the number of referrals to Dermatology was 58%. A savings of 2,475€ in transfers by ambulance and 550 working hours were made. The most common diagnoses were basal cell carcinoma (20%; n=79) and seborrheic keratosis (15.2%; n=60)., Conclusions: The addition of dermoscopy increases diagnosis concordance. Teledermatology is a useful system for patient triage and for decreasing the demand for hospital care, with an inherent resources saving., (Copyright © 2020 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Objective: 1) To analyze the implementation of multidisciplinary care models in psoriatic arthritis (PsA) patients, 2) To define minimum and excellent standards of care., Methods: A survey was sent to clinicians who already performed multidisciplinary care or were in the process of undertaking it, asking: 1) Type of multidisciplinary care model implemented; 2) Degree, priority and feasibility of the implementation of quality standards in the structure, process and result for care. In 6 regional meetings the results of the survey were presented and discussed, and the ultimate priority of quality standards for care was defined. At a nominal meeting group, 11 experts (rheumatologists and dermatologists) analyzed the results of the survey and the regional meetings. With this information, they defined which standards of care are currently considered as minimum and which are excellent., Results: The simultaneous and parallel models of multidisciplinary care are those most widely implemented, but the implementation of quality standards is highly variable. In terms of structure it ranges from 22% to 74%, in those related to process from 17% to 54% and in the results from 2% to 28%. Of the 25 original quality standards for care, 9 were considered only minimum, 4 were excellent and 12 defined criteria for minimum level and others for excellence., Conclusions: The definition of minimum and excellent quality standards for care will help achieve the goal of multidisciplinary care for patients with PAs, which is the best healthcare possible., (Copyright © 2018 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

This research-on-research study describes efforts to develop non-Cochrane systematic reviews (SRs) by analyzing demographical and time-course collaborations between international institutions using protocols registered in the International Prospective Register of Systematic Reviews (PROSPERO) or published in scientific journals. We have published an a priori protocol to develop this study. Protocols published in scientific journals were searched using the MEDLINE and Embase databases; the query terms "Systematic review" [Title] AND "protocol" [Title] were searched from February 2011 to December 2017. Protocols registered at PROSPERO during the same period were obtained by web scraping all non-Cochrane records with a Python script. After excluding protocols that had a fulfillment or duplication rate of less than 90%, they were classified as published "only in PROSPERO", "only in journals", or in "journals and PROSPERO". Results of data and metadata extraction using text mining processes were curated by two reviewers. These Datasets and R scripts are freely available to facilitate reproducibility. We obtained 20,814 protocols of non-Cochrane SRs. While "unique protocols" by reviewers' institutions from 60 countries were the most frequent, a median of 6 (2-150) institutions from 130 different countries were involved in the preparation of "collaborative protocols". The highest Ranked countries involved in overall protocol production were the UK, the U.S., Australia, Brazil, China, Canada, the Netherlands, Germany, and Italy. Most protocols were registered only in PROSPERO. However, the number of protocols published in scientific journals (924) or in both PROSPERO and journals (807) has increased over the last three years. Syst Rev and BMJ Open published more than half of the total protocols. While the more productive countries were involved in "unique" and "collaborative protocols", less productive countries only participated in "collaborative protocols" that were mainly published in PROSPERO. Our results suggest that, although most countries were involved in solitary production of protocols for non-Cochrane SRs during the study period, it would be useful to develop new strategies to promote international collaborations, especially with less productive countries., Competing Interests: The authors have declared that no competing interests exist.

Researchers are increasingly using on line social networks to promote their work. Some authors have suggested that measuring social media activity can predict the impact of a primary study (i.e., whether or not an article will be highly cited). However, the influence of variables such as scientific quality, research disclosures, and journal characteristics on systematic reviews and meta-analyses has not yet been assessed. The present study aims to describe the effect of complex interactions between bibliometric factors and social media activity on the impact of systematic reviews and meta-analyses about psoriasis (PROSPERO 2016: CRD42016053181). Methodological quality was assessed using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) tool. Altmetrics, which consider Twitter, Facebook, and Google+ mention counts as well as Mendeley and SCOPUS readers, and corresponding article citation counts from Google Scholar were obtained for each article. Metadata and journal-related bibliometric indices were also obtained. One-hundred and sixty-four reviews with available altmetrics information were included in the final multifactorial analysis, which showed that social media and impact factor have less effect than Mendeley and SCOPUS readers on the number of cites that appear in Google Scholar. Although a journal's impact factor predicted the number of tweets (OR, 1.202; 95% CI, 1.087-1.049), the years of publication and the number of Mendeley readers predicted the number of citations in Google Scholar (OR, 1.033; 95% CI, 1.018-1.329). Finally, methodological quality was related neither with bibliometric influence nor social media activity for systematic reviews. In conclusion, there seems to be a lack of connectivity between scientific quality, social media activity, and article usage, thus predicting scientific success based on these variables may be inappropriate in the particular case of systematic reviews.

Background: Phymatous rosacea is characterized by thickened skin and irregular surface contours as the result of variable combinations of fibrosis, sebaceous hyperplasia and lymphoedema. Otic phyma is rarely seen and has been rarely reported in the English literature., Methods: We present another case of this uncommon condition, frequently misdiagnosed, maybe due to its underrecognition., Results: Phymatous rosacea most commonly occurs on the nose, but may also develop on any sebaceous facial region, including the ears. Although it is a benign condition, there are significant morbidities associated with rosacea, and can even result in conductive deafness because of the obstruction of the external auditory canal., Conclusions: The knowledge of this entity may be important for clinicians, especially dermatologists, ENT specialists and plastic surgeons, for an appropriate treatment and follow-up., (Copyright © 2016 Elsevier Inc.

Angiosarcoma that develops on a limb with chronic lymphedema is called Stewart-Treves syndrome. This typically appears as a complication of a long course lymphedema located on the arm, after mastectomy and/or radiotherapy due to breast cancer. There are cases of Stewart-Treves syndrome in chronic lymphedema in the upper limb contralateral to the breast treated for cancer and in chronic lymphedema of the leg. We present two cases of this syndrome. The first corresponds to a typical syndrome of Stewart-Treves in an 83-year-old woman who was diagnosed of angiosarcoma in a chronic lymphedema territory secondary to mastectomy and radiotherapy due to breast cancer. The second case is much rarer, since it is a case of diffuse angiosarcoma of the leg in a 42-year-old man with a history of lymphedema. Due to the aggressive nature of this syndrome, knowledge and research on its treatment are necessary.
