Abstract:A 32-year-old male patient presented for 8 months an asymptomatic therapy-resistant acneiform eruption on his back and buttocks. Skin examination showed several inflammatory papules, which evolved to hyperpigmentation. At the same distribution non inflammatory papules, which resembled rice grains, were also observed. Light microscopy showed small keratin-filled cysts, with an epithelial multilayered wall, without granular layer. Keratin and some vellus hairs were identified inside the cyst, confirming the diagnosis of vellus hair cysts. Diagnosis of vellus hair cysts should be suspected in cases of multiple papules or therapy-resistant cases of acneiform eruptions. Keywords: Acne vulgaris; Acneiform eruptions; Follicular cyst; Isotretinoin; Young adult; Keratins Resumo: Um paciente de 32 anos apresentou há 8 meses uma erupção acneiforme resistente à terapêu-tica, localizada no dorso e nádegas. Ao exame apresentava inúmeras pápulas inflamatórias, que evoluiam para hiperpigmentação. Na mesma distribuição havia lesões não inflamatórias, lembrando grão de arroz. A microscopia óptica demonstrou cisto dérmico cuja parede era de epitélio estratificado, sem camada granular, preenchido de queratina e com pelos no interior, confirmando o diagnóstico de cisto de pelo veloso. Essa entidade deve ser suspeitada em casos de múltiplas pápulas ou erupções acneiformes resistentes à terapia.
ObjectivesThe scientific community assumes that rigorous methodology research is more likely to be published in high impact psychiatry journals (HIJ). We aimed to test which methodological variables could predict publication in HIJ.MethodsWe conducted a systematic review of the MEDLINE and EMBASE databases from 2013, January 1st to 2015, June 15th. Inclusion criteria were studies that were RCTs whose at least one arm of the study should be fluoxetine regarding adult patients (> 18 years old) with MDD. We performed logistic regression regarding the number of participants, intention-to-treat analysis, blinding, multicenter study, sample losses, positive result, sponsorship of pharmacy's industry, and h-index of the last author. A HIJ was considered if journal impact factor was above the median or 3rd quartile of our sample.ResultsForty-two studies were considered for the final analysis. The results of the univariate logistic regression found no differences between HIJ and low impact psychiatry journals for all methodological variables, except the h-index of the last author. By considering HIJ when impact factor was above the mean, h-index had an odds ratio = 1.09 (1.01–1.17), P = 0.02; considering HIJ when impact factor was above the 3rd quartile, h-index had an odds ratio = 1.07 (1.01–1.14), P = 0.02.DiscussionOur results indicate that the author productivity may be a relevant predictor for publication in a HIJ in the psychiatry/psychology field. Our study proposes that journals focus on identifying what are the relevant criteria for publication approval in the peer-review process.Disclosure of interestThe authors have not supplied their declaration of competing interest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
