Orbit and sinonasal metastasis as presenting sign of renal cell carcinoma.

BMJ Case Rep 2021 Apr 13;14(4). Epub 2021 Apr 13.

Department of Medicine, Rutgers New Jersey Medical School, Newark, New Jersey, USA

Orbit and sinonasal metastases are rare. Renal cell carcinoma (RCC) can metastasise to this region. We present the case of a 49-year-old woman with weight loss, diplopia and a rapidly growing facial mass. The initial diagnosis was a primary tumour and patient underwent excisional biopsy, which showed findings consistent with a diagnosis of RCC. On a subsequent focused review of system, the patient reported having intermittent haematuria. Imaging studies revealed a complex right renal mass as the primary tumour. Metastatic RCC should be in the differential diagnosis of patients with facial masses, especially if associated with symptoms suggestive of a systemic involvement such as haematuria. Despite treatment, patients with metastatic RCC tend to have a dismal prognosis. However, early stage diagnosis of metastatic disease can considerably limit surgical complications and improve survival rate in these patients.

[Performance of medical schools in Mexico: results from the Examen Nacional para Aspirantes a Residencias Médicas].

Salud Publica Mex 2019 Jul-Ago;61(4):495-503. Epub 2019 Jul 17.

Universidad de Guanajuato. Guanajuato, México.

Objective: To assess the performance of medical schools (FEM) by analyzing the results of their applicants in the Examen Nacional para Aspirantes a Residencias Médicas (ENARM).

Materials And Methods: Five performance criteria, two official and three created on purpose, were calculated from the ENARM-2016 and -2017 official databases to assess FEM performance.

Results: In 2016 and 2017, applicants registered from 112 and 115 FEM, respectively. Depending on the performance criteria, the FEM in the first place obtained 5 to 20 points more than the one placed second, and 23 to 98 points more than the FEM in the last place. Approximately 25% applicants were classified as "knowledge-deficient," and about 80% of these originated from less than one third of the FEM.

Conclusions: The ENARM results provide information on the performance of the FEM. Approximately one of every four applicants obtained scores lower than the approval threshold of any specialty.

Análisis bibliométrico de las revistas médicas del Sistema de Clasificación de Revistas Mexicanas de Ciencia y Tecnología.

Gac Med Mex 2019 ;155(3):258-265

Unidad de Investigación en Enfermedades Crónico-Degenerativas, Guadalajara, Jalisco, México.

Introduction: CONACYT's Mexican Science and Technology Journals Classification System (SCRMCYT) includes the area of medicine and health sciences (M&HS).

Objective: A bibliometric analysis of M&HS journals listed in SCRMCYT in 2018 was performed.

Method: Twelve characteristics related to indexation in the Web of Science Core Collection (WoSCC), Scopus, and PubMed databases were analyzed. Indexed journals were analyzed on whether they had recent indexed publications (2017 and 2018). Indexed journals' 50 most-cited articles in WoSCC and Scopus were analyzed.

Results: Of the 35 M&HS journals included in the 2018 SCRMCYT list, 31 (89 %) were indexed in Scopus (22 with indexed publications in 2017; 18 in 2018), 17 (49 %) in PubMed (10 with indexed publications in 2017 and 2018), and 12 (34 %) in WoSCC (12 with indexed publications in 2017; 8 in 2018). The 50 most-cited articles had been published only in 4 journals indexed in WoSCC and 5 in Scopus; 60 % were review articles.

Conclusions: Approximately half the 2018 SCRMCYT M&HS journals lack publications indexed in 2018; this suggests that national and international relevance of these journals can be improved.

Flaws in the design of the Examen Nacional para Aspirantes a Residencias Médicas produce inequity.

Salud Publica Mex 2019 Mar-Apr;61(2):125-135

Universidad Autónoma de Guadalajara. Zapopan, Jalisco, México.

Objective: To assess the assumption of 'equity' of Mexico's resident-selection assessment tool, the Examen Nacional para Aspirantes a Residencias Médicas (ENARM).

Materials And Methods: Official ENARM-2016 and -2017 databases were analyzed. Differences in the absolute number of correct answers (multivariable linear regression) and the number of applicants reaching their specialty minimum score (SMS) per test day (odds ratio [OR]) were calculated. Applicants affected by test-day inequity were estimated.

Results: There were 36 114 applicants in 2016, and 38 380 in 2017. In 2016, day-2 applicants had significantly higher scores and more reached the SMS than on days 1-3-4 (OR 1.55), and 5 (OR 3.8); 3 565 non-passing applicants were affected by inequity (equivalent to 44.64% of those selected). In 2017, day-1 and -2 applicants had significantly higher scores and more reached the SMS than on days 3-4 (OR 1.85), and 5 (OR 4.04); 3,155 non-passing applicants were affected by inequity (37.2% of those selected).

Conclusions: Analysis of official ENARM databases does not support the official attribution of equity, suggesting the test should be redesigned.

Fifteen-year trend in information on the World Wide Web for patients with rheumatoid arthritis: evolving, but opportunities for improvement remain.

Rheumatol Int 2016 Sep 13;36(9):1281-9. Epub 2016 Jun 13.

Unidad de Investigacion en Enfermedades Cronico-Degenerativas, Colomos 2292, Providencia, 44620, Guadalajara, Jalisco, Mexico.

The aim of this study was to assess the changes in the characteristics of rheumatoid arthritis information on the Internet over a 15-year period and the positioning of Web sites posted by universities, hospitals, and medical associations. We replicated the methods of a 2001 study assessing rheumatoid arthritis information on the Internet using WebCrawler. All Web sites and pages were critically assessed for relevance, scope, authorship, type of publication, and financial objectives. Differences between studies were considered significant if 95 % confidence intervals did not overlap. Additionally, we added a Google search with assessments of the quality of content of web pages and of the Web sites posted by medical institutions. There were significant differences between the present study's WebCrawler search and the 2001-referent study. There were increases in information sites (82 vs 36 %) and rheumatoid arthritis-specific discussion pages (59 vs 8 %), and decreases in advertisements (2 vs 48 %) and alternative therapies (27 vs 45 %). The quality of content of web pages is still dispersed; just 37 % were rated as good. Among the first 300 hits, 30 (10 %) were posted by medical institutions, 17 of them in the USA. Regarding readability, 7 % of these 30 web pages required 6 years, 27 % required 7-9 years, 27 % required 10-12 years, and 40 % required 12 or more years of schooling. The Internet has evolved in the last 15 years. Medical institutions are also better positioned. However, there are still areas for improvement, such as the quality of the content, leadership of medical institutions, and readability of information.

Readability, relevance and quality of the information in Spanish on the Web for patients with rheumatoid arthritis.

Reumatol Clin 2017 May - Jun;13(3):139-144. Epub 2016 May 31.

Unidad de Investigación en Enfermedades Crónico-Degenerativas, Guadalajara, México; Vicerrectoría Académica, Universidad Autónoma de Guadalajara, Zapopan, México.

Background: Education is a major health determinant and one of the main independent outcome predictors in rheumatoid arthritis (RA). The use of the Internet by patients has grown exponentially in the last decade.

Objective: To assess the characteristics, legibility and quality of the information available in Spanish in the Internet regarding to rheumatoid arthritis.

Material And Methods: The search was performed in Google using the phrase rheumatoid arthritis. Information from the first 30 pages was evaluated according to a pre-established format (relevance, scope, authorship, type of publication and financial objective). The quality and legibility of the pages were assessed using two validated tools, DISCERN and INFLESZ respectively. Data extraction was performed by senior medical students and evaluation was achieved by consensus.

Results: The Google search returned 323 hits but only 63% were considered relevant; 80% of them were information sites (71% discussed exclusively RA, 44% conventional treatment and 12% alternative therapies) and 12.5% had a primary financial interest. 60% of the sites were created by nonprofit organizations and 15% by medical associations. Web sites posted by medical institutions from the United States of America were better positioned in Spanish (Arthritis Foundation 4th position and American College of Rheumatology 10th position) than web sites posted by Spanish speaking countries.

Conclusions: There is a risk of disinformation for patients with RA that use the Internet. We identified a window of opportunity for rheumatology medical institutions from Spanish-speaking countries to have a more prominent societal involvement in the education of their patients with RA.
