Factors influencing citations to systematic reviews in skin diseases: a cross-sectional study through Web of Sciences and Scopus

AbstractBACKGROUND:Disseminating information derived from systematic reviews is a fundamental step for translating evidence into practice.OBJECTIVE:To determine which features of dermatological SR are associated with systematic review dissemination, using citation rates as an indicator.METHODS:Dermatological systematic reviews published between 2008 and 2012 were obtained from Scopus, the ISI Web of Sciences and the Cochrane Skin Group. Bibliometric data of every systematic review were collected and analyzed.RESULTS:A total of 320 systematic reviews were analyzed. Univariable analysis showed that the journal impact factor, number of authors, and total references cited were positively associated with the number of citations. There was a significant difference in the median number of citations with regard to the corresponding author's country, type of skin disease, type of funding, and presence of international collaboration. Cochrane reviews were significantly associated with a lower number of citations. Multivariable analysis found that the number of authors, number of references cited and the corresponding author from United Kingdom were independently correlated with many citations. Cochrane systematic reviews tended to be independently associated with a lower number of citations.CONCLUSIONS:Citation number to systematic reviews may be improving by increasing the number of authors, especially collaborative authors, and the number of cited references. The reasons for the association of Cochrane SRs with fewer citations should be addressed in future studies.

Exantema asimétrico en una niña

El exantema laterotorácico unilateral es un exantema poco frecuente, de etiología incierta y curso benigno autolimitado. Nuestro objetivo fue describir este diagnóstico poco conocido y ayudar al pediatra en el reconocimiento de esta entidad. Presentamos una paciente de sexo femenino de 23 meses de edad, con pápulas y placas dérmicas pruriginosas en dorso, axila y brazo derecho posterior a infección respiratoria por virus influenza, sin respuesta a hidrocortisona tópica. Se diagnosticó exantema laterotorácico unilateral y se indicó hidroxicina para manejo sintomático. El exantema laterotorácico unilateral afecta a niños de 2 años en promedio, con predominio estacional, frecuente pródromo y distribución característica. A pesar de ser benigno, es importante reconocerlo para realizar un adecuado manejo del paciente y de las inquietudes familiares.

Unilateral laterothoracic exanthem is an infrequent condition, of unknown cause and benign self-limited course. Our goal was to describe this rare entity and to help the pediatrician in its recognition. We present a 23-months-old girl with pruritic eccematous papules and plaques on her right back, axilla and arm after influenza infection, without response to topical hydrocostisone. Unilateral laterothoracic exantema was diagnosed. Hydroxyzine was indicated for symptomatic relief. Unilateral laterothoracic exanthem usually affects two year-old children, with a seasonal pattern, frequent prodromic symptoms and characteristical distribution. Despite being a benign condition, it is important to recognize it for adequate management of the patient and the family’s worries.

Factores socioeconómicos e Indicadores de riesgo de Caries en responsables primarios de niños preescolares / Socio-Economic Factors and Risk Indicators for Caries in Primary Caregivers of Pre-School Children

Objetivo: Evaluar la frecuencia de indicadores de riesgo de Caries de la infancia temprana (CIT) según datos socioeconómicos de los responsables primarios (RP) de niños preescolares. Material y Método: Estudio observacional, descriptivo de corte transverso con componentes analíticos, en 92 RP de niños de 0 a 5 años que acudieron a consulta pediátrica en un hospital público y uno privado; y aceptaron participar del estudio. Fue elaborado un formulario semi-estructurado con 9 preguntas en relación a los responsables, 8 a los niños; el cual fue validado por especialistas. Las variables fueron: edad de los niños, nivel de educación, ingreso familiar, tipo de servicio odontológico y una selección de indicadores de CIT. La tabulación de datos se llevó a cabo en una planilla Excel 2010. Se hicieron análisis de frecuencia y asociación de variables (estadígrafo z) con un alfa = 0.05. Resultados: Tan solo 10 RP (10.86%) señalaron al Flúor como una sustancia capaz de fortalecer a las piezas dentarias. 89 de ellos (96.73%) reportaron experiencia pasada de padecimiento de Caries dental. Se encontró asociación estadística para: Motivo de consulta tratamiento con: Ingreso familiar (p=0.0002); Nivel de educación (p=0.004) y Tipo de servicio odontológico (p=0.00003) como así también para Creencia fatalista sobre salud oral con: Nivel de educación e ingreso familiar, ambos con valor p=0.04. Conclusión: Se verificaron elevadas frecuencias para algunos indicadores de riesgo de CIT, como también variación en la frecuencia de estos indicadores de riesgo según indicadores socioeconómicos utilizados, con algunas importantes asociaciones entre variables; datos que pueden influir en la identificación de pacientes de riesgo y en acciones para controlar la enfermedad .

Objective: To assess the frequency of risk factors for earlychildhood caries (ECC) according to socio-economic data of primary care-takers (PCTs) for pre-school age children. Material and Methods: We conducted an observational, descriptive, cross-sectional study with analytic components in 92 PCTs of children aged 0-5 years who consulted in the pediatric sections of 1 public and 1 private hospital and agreed to participate in the study. A semi-structured form validated by specialists was created with 9 questions related to the care-takers and 8 questions concerning the children. The variables studied were child age, educational level, family income, type of dental care performed, and selected ECC indicators. Tabulation of data was done using an Excel 2010 spreadsheet. Frequency analysis and variable association (Z test) were performed with á deemed to be 0.05. Results: Only 10 primary care-takers (10.86%) identified fluoride as a substance capable of strengthening teeth, while 89 (96.73%) reported a history of dental caries. Statistical association was found for: presenting complaint with family income (p=0.0002), education level (p=0.004), and type of dental care performed (p=0.00003); as well as between a fatalistic attitude toward dental health and educational level (p=0.04) and family income (p=0.04). Conclusion: A high frequency was found for some ECC risk indicators, as was a variation in the frequency of these risk indicators according to the socio-economic indicators used, with important associations found between variables, findings that can influence the identification of at-risk patients and disease management
