RESUMO

ABSTRACT Medical specialties have recognized that breaking bad news assists clinical practice by mitigating the impact of difficult conversations. This scenario also encourages various studies on breaking bad news in ophthalmology since certain ocular diagnoses can be considered bad news. Thus, the objective is to review the scientific literature on breaking bad news in ophthalmology. The literature databases like MEDLINE/PUBMED, EMBASE, LILACS, SCOPUS, COCHRANE, and SCIELO, were screened for related research publications. Two independent reviewers read all the articles and short-listed the most relevant ones. Seven articles, in the formats of original article, review, editorial, oral communication, and correspondence, were reviewed. Conclusively it reveals that ophthalmologists are concerned with communicating bad news effectively but lack related studies. Nevertheless, there is a growing realization that training in breaking bad news can increase physicians' confidence during communication, thus, benefiting the therapeutic relationship with the patient and his family. Therefore, it would be valuable to include breaking bad news training in the curriculum of residencies.


RESUMO O reconhecimento sobre a comunicação de más notícias como mitigadora de conversas difíceis por outras especialidades médicas, incentiva o estudo desta temática na oftalmologia. Sendo assim, o objetivo deste estudo é revisar a produção de pesquisas científicas sobre a comunicação de más notícias em oftalmologia. Para isso, foi realizada uma revisão de literatura. As bases de dados utilizadas foram MEDLINE/PUBMED, EMBASE, LILACS, SCOPUS, COCHRANE e SCIELO. Dois revisores independentes leram todos os artigos e selecionaram a amostra final. Sete artigos foram escolhidos nos formatos de artigo original, revisão, editorial, comunicação oral e correspondência. Os oftalmologistas estão preocupados em comunicar as más notícias de forma eficaz, mas faltam estudos sobre o tema. No entanto, há uma crescente percepção de que o treinamento de comunicação de más notícias aumenta a confiança dos médicos na comunicação, beneficiando a relação terapêutica. Portanto, seria valioso incluir este treinamento no currículo das residências.

RESUMO

ABSTRACT This report describes a case of retinal racemose hemangioma that first presented as a vitreous hemorrhage. The authors present the case of a 47-year-old woman with a sudden 5-day painless visual loss in her left eye. At the first visit, the best-correct visual acuities were 20/20 in the right eye and hand motions in the left eyes. Ultrasonography showed an attached retina and a massive vitreous hemorrhage. Pars plana vitrectomy was performed and a dilatation of large vessels was detected bulging from the optic disc. The best-correct visual acuities on day 30 postoperatively was 20/25 in the left eye. Fundus angiography and spectral-domain optical coherence tomography angiography showed anomalous arteriovenous communications with no intervening capillaries. The diagnosis was racemose hemangioma, an arteriovenous malformation of group 2 retina based on the Archer classification.


RESUMO Este relato descreve um caso de hemangioma racemoso da retina que se apresentou inicialmente como hemorragia vítrea. Os autores apresentam o caso de uma mulher de 47 anos com perda visual súbita e indolor 5 dias antes no olho esquerdo. Na primeira visita, a melhor acuidade visual corrigida foi de 20/20 no olho direito e movimentos das mãos no olho esquerdo. A ultrassonografia mostrou uma retina aderida e uma hemorragia vítrea maciça. Foi realizada vitrectomia pars plana, sendo detectada proliferação de grandes vasos salientes do disco óptico. A acuidade visual no dia 30 de pós-operatório foi de 20/25 no olho esquerdo. A angiografia de retina e a angiotomografia de coerência óptica de domínio espectral mostraram comunicações arteriovenosas anômalas sem capilares intermediários. O diagnóstico foi hemangioma racemoso, uma malformação arteriovenosa da retina do grupo 2 com base na classificação de Archer.

RESUMO

BACKGROUND: Antiangiogenic therapy has proved to be an important therapeutic tool for many retinal vascular diseases; however, its availability is limited in developing countries. This study sought to describe the bevacizumab vial sharing process and to evaluate the impact of this repackaging system on the costs incurred in a Brazilian public hospital. METHOD: This retrospective study compared the number and costs of intravitreal antiangiogenic injections approved via court order in the first year of the study (2015) to the number and costs of the bevacizumab injections provided through the use of vial sharing in the second year of the study (2016). Vial sharing consists of the traditional process used to repackage bevacizumab; in this case, however, the drug samples used were the residual volume from the preparation of bevacizumab for oncology patients. The hospital adhered to the guidelines established by the Brazilian Health Surveillance Agency (ANVISA). RESULTS: In the first year of the study and using medication obtained through court orders, 550 intravitreal injections were performed in the ophthalmology ambulatory care center. Based on local pricing tables, the total cost of the medication was BRL$1,036,056.25 (USD$267,546.58), and the average cost of each application was BRL$1883.74 (USD$486.45). In the second year of the study, 1081 intravitreal applications were performed at the same hospital using doses obtained through bevacizumab vial sharing. The total cost was BRL$21,942.49 (USD$5663.30) and the per-unit cost was BRL$20.30, or USD$5.23 (a savings of 97.88%). CONCLUSION: This study found that bevacizumab vial sharing led to a significant reduction in public health care costs associated with antiangiogenic treatment and increased the availability of the drug to public health care patients. These results can be extrapolated to other types of drugs and health care systems.

RESUMO

PURPOSE: To test the ability of machine learning classifiers (MLCs) using optical coherence tomography (OCT) and standard automated perimetry (SAP) parameters to discriminate between healthy and glaucomatous individuals, and to compare it to the diagnostic ability of the combined structure-function index (CSFI), general ophthalmologists and glaucoma specialists. DESIGN: Cross-sectional prospective study. METHODS: Fifty eight eyes of 58 patients with early to moderate glaucoma (median value of the mean deviation = -3.44 dB; interquartile range, -6.0 to -2.4 dB) and 66 eyes of 66 healthy individuals underwent OCT and SAP tests. The diagnostic accuracy (area under the ROC curve-AUC) of 10 MLCs was compared to those obtained with the CSFI, 3 general ophthalmologists and 3 glaucoma specialists exposed to the same OCT and SAP data. RESULTS: The AUCs obtained with MLCs ranged from 0.805 (Classification Tree) to 0.931 (Radial Basis Function Network, RBF). The sensitivity at 90% specificity ranged from 51.6% (Classification Tree) to 82.8% (Bagging, Multilayer Perceptron and Support Vector Machine Gaussian). The CSFI had a sensitivity of 79.3% at 90% specificity, and the highest AUC (0.948). General ophthalmologists and glaucoma specialists' grading had sensitivities of 66.2% and 83.8% at 90% specificity, and AUCs of 0.879 and 0.921, respectively. RBF (the best MLC), the CSFI, and glaucoma specialists showed significantly higher AUCs than that obtained by general ophthalmologists (P<0.05). However, there were no significant differences between the AUCs obtained by RBF, the CSFI, and glaucoma specialists (P>0.25). CONCLUSION: Our findings suggest that both MLCs and the CSFI can be helpful in clinical practice and effectively improve glaucoma diagnosis in the primary eye care setting, when there is no glaucoma specialist available.

RESUMO

MYOC encodes a secretary glycoprotein of 504 amino acids named myocilin. MYOC is the first gene to be linked to juvenile open-angle glaucoma (JOAG) and some forms of adult-onset primary open-angle glaucoma (POAG). The gene was identified as an up-regulated molecule in cultured trabecular meshwork (TM) cells after treatment with dexamethasone and was originally referred to as trabecular meshwork-inducible glucocorticoid response (TIGR). Elevated intraocular pressure (IOP), due to decreased aqueous outflow, is the strongest known risk factor for POAG. Increasing evidence showed that the modulation of the wild-type (wt) myocilin protein expression is not causative of glaucoma while some misfolded and self-assembly aggregates of mutated myocilin may be associated with POAG in related or unrelated populations. The etiology of the disease remains unclear. Consequently, a better understanding of the molecular mechanisms underlying POAG is required to obtain early diagnosis, avoid potential disease progression, and develop new therapeutic strategies. In the present study, we review and discuss the most relevant studies regarding structural characterizations, expressions, molecular interactions, putative functions of MYOC gene and/or its corresponding protein in POAG etiology.

RESUMO

PURPOSE: To evaluate the reproducibility of water drinking test (WDT) performed at different times of the day, in primary open angle glaucoma (POAG) patients and normal individuals. METHODS: Fifteen patients with POAG and 30 normal individuals underwent three WDTs at different times of the day (7 AM, 12 PM, and 5 PM) on 3 different days. Test results in POAG patients and normal individuals were compared. Agreement and correlation of intraocular pressure (IOP) baseline levels, peak levels, and IOP change (peak IOP--baseline IOP) on tests performed at different times were evaluated. Only right eye measurements were analyzed. RESULTS: Mean baseline IOP, peak IOP and IOP change were significantly higher in POAG patients than in normal individuals, at all time intervals (p<0.05). The Bland-Altman analysis demonstrated limits of agreement for IOP peak levels and IOP changes larger than the clinically acceptable (>3 mmHg), even though Pearson's test revealed good correlation among the results. CONCLUSION: The mean IOP peak and mean IOP change observed during WDT are significantly higher in POAG patients than in control individuals. Low levels of agreement among WDTs performed at different times of the day suggest a poor reproducibility of WDT, which may limit its applicability for the diagnosis and follow-up of glaucoma.

OBJETIVO: Avaliar a reprodutibilidade do teste de sobrecarga hídrica (TSH) em diferentes horários em que é realizado, em pacientes com glaucoma primário de ângulo aberto (GPAA) e em indivíduos normais. MÉTODOS: Quinze pacientes com GPAA e 30 indivíduos normais foram submetidos a três TSHs, realizados em diferentes horários do dia (às 7:00 h, 12:00 h e 17:00 h), em três dias diferentes. Foram comparados os resultados dos testes em pacientes com GPAA e indivíduos normais. Foram analisadas a concordância e a correlação entre os valores de medida basal, pico e variação de pressão intraocular (PIO) (pico de PIO - PIO basal) nos testes realizados nos diferentes horários. Apenas as medidas do olho direito foram analisadas. RESULTADOS: Os valores médios de medida basal, pico e variação de PIO foram significativamente maiores nos pacientes glaucomatosos que nos indivíduos normais, em todos os horários (p<0,05). A análise de Bland-Altman apresentou limites de concordância de pico e variação de PIO maiores do que o clinicamente aceitável (>3 mmHg), apesar de o teste de Pearson demonstrar boa correlação entre os resultados. CONCLUSÃO: O TSH apresenta valores de pico e variações da PIO significativamente maiores em pacientes glaucomatosos que em indivíduos normais. Os baixos níveis de concordância entre os TSHs realizados em diferentes horários do dia sugerem uma baixa reprodutibilidade do TSH, que pode limitar sua aplicabilidade para diagnóstico e acompanhamento do glaucoma.

RESUMO

Objetivo: Avaliar as causas de glaucoma neovascular (GNV), bem como os fatores que influenciam prognóstico e o resultado do tratamento efetuado. Métodos: Estudou-se retrospectivamente um grupo de 38 pacientes com diagnóstcos de GNV atendidos consecutivamentes no setor de Glaucoma da UNICAMP entre setembro de 1996 e março de 1997. Resultados: A principal causa de GNV encontrada foi retinopatia diabética proliferativa (RDP)em 18 pacientes (47,4 por cento), seguida de oclusäo da veia central de retina (OVCR) em 14 (36,8 por cento). O único fator progóstico positivamente correlacionado à acuidade visual final foi a acuidade visual inicial (p=0,004). Näo houve associaçäo entre pressäo intraocular (PIO) inicial e acuidade visual final, nem tampouco entre extensäo de goniossinéquias e acuidade visual final(p>0,05). Entre os 38 pacientes, 8(21,1por cento) foram submetidos a cirurgia, onde observamos uma diminuiçäo significativa da PIO de 39,75ñ10,99mmHg para 21,88ñ12,14mmHg(p=0,01,)5(13,1por5 cento)obtiveram reduçäo da PIO de 31,4ñ7,4mmHg para 16,0ñ4,6 mmHg graças a tratamento clínico da PIO( medicaçäo anti-glaumatosa + ablaçäo retiniana) (p=0,01).Os demais 25 pacientes (65,8 por cento) näo apresentavam prognóstico visual suficiente que justificasse cirurgia (acuidade visual menor ou igual a percepçäo luminosa). Ao final do período de seguimento, 71,1 por cento dos pacientes apresentaram acuidade visual pior ou igual à percepçäo de luminosa. Conclusäo: O GNV mostrou ser moléstia de difícil controle terapêutico e com prognóstico visual ruim. Na tentativa de minimizar esta evoluçäo desfavorável, propusemos um fluxograma de abordagem do paciente com GNV.
