Gamasoidose ilustrada: do ninho à dermatoscopia

Gamasoidosis (acariasis, avian-mite dermatitis or bird-mite dermatitis) is a challenging diagnosis that is becoming more common because of the frequent use of window air conditioners in tropical countries. These devices may serve as shelters for nests of urban birds such as pigeons. Dermatologists should become familiar with this infestation to establish the correct diagnosis and treatment

Orthodontic bracket bonding techniques and adhesion failures : a systematic review and meta-analysis

This systematic review compared the bonding failures of orthodontic brackets bonded by indirect or direct techniques. Data sources: The searched databases were Cochrane Library, LILACS, BBO, PubMed, Scopus, Web of Science. A search for randomized clini

Seasonal and daylight saving time fluctuations in Google searches for scalp seborrheic dermatitis

Scalp seborrheic dermatitis, or dandruff, is thought to worsen during the winter when there is later sunrise and less daylight. This study investigates trends in search engine interest for the term "dandruff" as they relate to changes in daylight, sunrise, and seasonality. We investigated the search interest in several countries of varying latitudes over a five-year period, and we explore the effect of daylight saving time on disease interest within two cities in the United States. We discuss our findings in the context of hormonal changes and skincare/behavior

BOB MARLEY'S DISEASE: CEREBRAL METASTASIS OF ACRAL MELANOMA

Bob Marley's had a great importance to Jamaica, Caribbean popular music, and Pan-Africanism. Under the name of the Wailers, several Marley's success reggae albums were recorded between 1969 and 1975. After this, at the solo career, he was placed as the most impor- tant reggae singer. The disease that ruined Bob Marley was an acral melanoma (right hallux) that had a late diagnosis and treatment, followed by metastases to the abdomen, the lungs and the brain. Seizures have been the warning sign that the melanoma had spread, three years after the initial injury. We presented here the history of the disease of this famous singer and reported another patient with a case quite similar to him, calling his illness as “Bob Marley'

Microsynthetics in waters of the South American Pantanal

Microplastics are an emerging global threat to freshwater ecosystems. There is a growing number of microplastic studies in wetlands and floodplains such as the Pantanal. Microplastics in the Pantanal’s water courses, lakes, and floodplains were sampled with a plankton net in 16 locations in the Pantanal lowlands at varying distances from their potential urban sources over 2 years. Microplastics from the water samples were separated from sediments and organic matter and examined under a stereomicroscope to be identified and counted. Visual determination was then confirmed by RAMAN spectrometry. We found 730 microplastics. The average ± std microplastic concentration was 38 ± 16 x/m3, ranging between 10 and 100 x/m3. Fibres, fragments, and films represented 68%, 28%, and 4%, respectively, of the total microplastics. Surprisingly, a synthetic blue fibre of non-identified composition accounted for 51.0% of the microplastics. Other identified polymers included PP (18.2%), PET (16.9%), PVC (5.1%), PVA (4.4%) and LDPE (4.4%). The blue fibres, PP, and PET were found at all sampling locations. Microplastic concentrations varied from 27 ± 12 x/m3 to 48 ± 21 x/m3 across the sampling sites. Microplastics’ average size was 0.51 ± 0.21 mm, ranging from 0.06 to 0.97 mm. In the study area, the average seasonal concentrations varied from 34 ± 11 to 43 ± 18 x/m3 during the 2 years study period (2018–2019). In lentic environments, the median concentrations (30 x/m3) were significantly lower than in the lotic ones (40 x/m3). Urban human activities are a potential source of microplastics as the concentration of these increased significantly with the population of the nearest human agglomeration. These results indicate widespread contamination of the Pantanal waters by microplastics. Furthermore, a microsynthetic of indeterminate composition is found everywhere in the Pantanal, and more research is urgently needed to determine its composition and sources. The contamination by micropolymers and other microsynthetics will likely impact the Pantanal biota and, eventually, humans living in these floodplains

Critérios brasileiros de elegibilidade à doação de sangue para pacientes dermatológicos

A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic procedures as determined by Ministerial Directive #1353/2011 by the Ministry of Health and current internal regulations of the Hemotherapy Center of Ribeirão Preto, a regional reference center in hemotherapeutic procedures. Criteria for permanent inaptitude: autoimmune diseases (>1 organ involved), personal history of cancer other than basal cell carcinoma, severe atopic dermatitis or psoriasis, pemphigus foliaceus, porphyrias, filariasis, leprosy, extra pulmonary tuberculosis or paracoccidioidomycosis, and previous use of etretinate. Drugs that impose temporary ineligibility: other systemic retinoids, systemic corticosteroids, 5-alpha-reductase inhibitors, vaccines, methotrexate, beta-blockers, minoxidil, anti-epileptic, and anti-psychotic drugs. Other conditions that impose temporary ineligibility: occupational accident with biologic material, piercing, tattoo, sexually transmitted diseases, herpes, and bacterial infections, among others. Discussion: Thalidomide is currently missing in the teratogenic drugs list. Although finasteride was previously considered a drug that imposed permanent inaptitude, according to its short halflife current restriction of 1 month is still too long. Dermatologists should be able to advise their patients about proper timing to donate blood, and discuss the impact of drug withdrawal on treatment outcomes and to respect the designated washout periods

Revitalização da biblioteca de uma escola municipal: possibilidade de usos de resíduos descartáveis como ferramentas pedagógicas

Dentre os problemas ambientais que afetam a população está o não gerenciamento dos resíduos sólidos. No Brasil, em 2022, 39% destes não receberam destinação adequada. Dar uma finalidade econômica, correta e sustentável para os resíduos ainda é um desafio. O objetivo deste projeto foi identificar a potencialidade didática da utilização de resíduos sólidos urbanos (RSU) na revitalização da biblioteca de uma escola de educação básica do município de Canoinhas-SC, para fomentar a consciência sustentável por meio de uma ação de extensão do protagonismo discente ofertada pelo Instituto Federal de Santa Catarina campus Canoinhas. A ação mostra a importância da curricularização da extensão e foi dividida em cinco etapas: levantamento bibliográfico acerca do tema, levantamento das necessidades da biblioteca a ser revitalizada, elaboração do projeto de revitalização, produção dos mobiliários utilizando RSU e revitalização do espaço
