Cutaneous reactions due to the use of epidermal growth factor receptor inhibitors: two case reports

An increase in the expression of epidermal growth factor receptors (EGFR) is involved in the stimulation of tumor development. EGFR inhibitors have shown efficacy in the treatment of neoplasms of the head, neck, colon and lung. EGFR when inhibited can cause cutaneous reactions in more than 50% of the patients. They are usually reversible, but when severe, limit the use of the drug. Papulopustulars lesions in the face and upper torso are the most common, as well as xerosis, hair and nail changes. There is a direct relationship between the degree of cutaneous toxicity and the antitumoral response. An adequate dermatologic approach is necessary for an effective therapy against cancer.O aumento da expressão de receptores do fator de crescimento epidérmico (EGFR) está envolvido no estímulo ao crescimento tumoral. Seus inibidores demonstraram eficácia no tratamento de neoplasias de cabeça e pescoço, cólon e pulmão.A inibição do EGFR pode determinar reações cutâneas em mais de 50% dos pacientes. Em geral, são reversíveis, mas, quando graves, limitam o uso da droga. Lesões papulopustulosas em face e tronco são as mais comuns, além de xerose, alterações ungueais e dos pelos. A intensidade da toxicidade cutânea tem relação direta com a resposta antitumoral.

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Síndrome de Dubin-Johnson: a propósito de um caso

A síndrome de Dubin-Johnson (SDJ) é caracterizada por um defeito hereditário do metabolismo biliar que provoca retenção de bilirrubina conjugada nas células hepáticas. Não há predomínio de sexo, com maior prevalência em judeus iranianos. Este estudo objetiva relatar um caso de SDJ e revisar a respectiva literatura, enfocando seus aspectos diagnósticos e terapêuticos

Chemotherapy in the elderly: translation of hurria’s toxicity score to portuguese

OBJECTIVE: To describe the translation and transcultural adaptation of Hurria’s chemotherapy toxicity score, a prediction tool to estimate chemotherapy toxicity in the elderly. METHODS: The original English version of the score was translated to Portuguese using the forward and backward translation technique, as described by Guilemin. RESULTS: The translation was performed by two Brazilians (a physician and a professional translator), both fluent in English. Two professionals from a specialized linguistic service, not related to the study, then carried out the backward translation. Finally, a medical committee composed of oncologists, geriatricians, and hematologists discussed the consistency of the score, choosing a final version of the instrument in Portuguese. This version was piloted-tested in medical charts in an Oncogeriatric service, with high reliability as tested by Kappa statistic test. CONCLUSION: The final version of Hurria’s chemotherapy toxicity score in Portuguese proved to be an easy, clear, and quick tool, suitable for use in clinical practice.</p

Tempo de espera para a radioterapia como um fator prognóstico em pacientes com glioblastoma em um cenário de disparidades médicas

Objective To evaluate the effect of waiting time (WT) to radiotherapy (RT) on overall survival (OS) of glioblastoma (GBM) patients as a reliable prognostic variable in Brazil, a scenario of medical disparities. Method Retrospective study of 115 GBM patients from two different health-care institutions (one public and one private) in Brazil who underwent post-operative RT. Results Median WT to RT was 6 weeks (range, 1.3-17.6). The median OS for WT ≤ 6 weeks was 13.5 months (95%CI , 9.1-17.9) and for WT > 6 weeks was 14.2 months (95%CI, 11.2-17.2) (HR 1.165, 95%CI 0.770-1.762; p = 0.470). In the multivariate analysis, the variables associated with survival were KPS (p < 0.001), extent of resection (p = 0.009) and the adjuvant treatment (p = 0.001). The KPS interacted with WT to RT (HR 0.128, 95%CI 0.034-0.476; p = 0.002), showing that the benefit of KPS on OS depends on the WT to RT. Conclusion No prognostic impact of WT to RT could be detected on the OS. Although there are no data to ensure that delays to RT are tolerable, we may reassure patients that the time-length to initiate treatment does not seem to influence the control of the disease, particularly in face of other prognostic factors.Objetivo Avaliar o efeito do tempo de espera (TE) até radioterapia na sobrevida global de pacientes com glioblastoma como um fator prognóstico confiável. Método Estudo retrospectivo de 115 pacientes com glioblastoma, que foram submetidos à radioterapia pós-operatória, em dois serviços diferentes no Brasil (um público e outro privado). Resultados Mediana de TE para radioterapia foi de 6 semanas (variação, 1,3-17,6). A mediana de sobrevida para TE ≤ 6 semanas foi de 13,5 meses (IC95%, 9,1-17,9) e para TE > 6 semanas foi de 14,2 meses (IC95%, 11,2-17,2) (HR 1,165, 0,770-1,762; p = 0,470). Na análise multivariada, as variáveis associadas à sobrevida foram perfomance status (p < 0,001), extensão da ressecção (p = 0,009) e tratamento adjuvante (p = 0,001). Conclusão Não se observou impacto prognóstico para TE até a radioterapia na sobrevida. Diante de outros fatores prognósticos, é possível assegurar de que o espaço de tempo até a radioterapia não parece influenciar o controle da doença
