ABSTRACT

PURPOSE: The purpose of this study was to evaluate the feasibility of treating aniridia-associated keratopathy with a nonpenetrating artificial cornea in 2 patients with corneal blindness secondary to aniridia. METHODS: This was a prospective, nonrandomized, interventional study of 2 consecutive patients with corneal blindness caused by aniridia. Ophthalmological examination was performed before the nonpenetrating keratoprosthesis surgery and then repeated 1, 7, 15, 30, 90, and 180 days and subsequently every 90 days thereafter. Optical coherence tomography was performed 90 days postsurgery to assess the position of the implant. RESULTS: Visual acuity improved significantly after the KeraKlear surgery. Postoperative findings included periprosthetic corneal thinning, neovascularization, and retroprosthetic opacity. CONCLUSIONS: KeraKlear nonpenetrating artificial corneas represent a promising alternative to keratolimbal allografts and Boston keratoprosthesis for the treatment of aniridia-associated keratopathy.

ABSTRACT

Abstract Purpose: To report etiological diagnosis, predisposing risk factors, therapeutic strategies and visual outcome of patients treated at the Department of Ophthalmology of Federal University of São Paulo. Methods: This is a retrospective, descriptive, and observational study from medical and laboratory records of the Department of Ophthalmology of Federal University of São Paulo, including all patients with culture proven fungal keratitis in 5 years, from October 2012 through October 2017. Results: There were 2260 fungi microbiologic test requests. Of these, 140 samples had positive cultures for fungi and sixty-six patients were followed at our clinic. Forty-five patients (68.2%) were men, and the mean age was 48.06 (±17.39) years. Fusarium spp. was the most frequently isolated fungus (32 cases; 48.5%), followed by Candida parapsilosis (12 cases; 18.2%). Thirty-four patients (51.5%) underwent intracameral injection of amphotericin B (5 µg per 0.1 ml). In 11 patients (32.3%), infection was eradicated after intracameral amphotericin B associated to topical antifungal treatment and, in 23 patients (67.7%), therapeutic keratoplasty was needed. No complication related to intracameral amphotericin B injection was observed in this series. Forty-three patients (65.1%) ended up with therapeutic keratoplasty. Three patients (4.5%) evolved to evisceration or enucleation. At the last follow-up visit, 53 patients (80.3%) had visual acuity worse than 20/200. Conclusion: Despite current antifungals drugs and distinct administration strategies, fungal keratitis remains challenging. Delayed antifungal therapy may explain poor clinical outcomes. Intracameral amphotericin B associated to topical antfungal treatment seems to be a safe and helpful alternative for non-responsive fungal keratitis. But it is important to formulate other treatment strategies, hence to improve patients' outcomes, since most patients ended-up with significant visual impairment even after current treatment.


Resumo Objetivo: Descrever diagnósticos etiológicos, fatores de risco, estratégias terapêuticas e resultados visuais de pacientes com ceratite fúngica tratados no Departamento de Oftalmologia da Universidade Federal de São Paulo. Métodos: Trata-se de um estudo retrospectivo, descritivo e observacional, a partir da análise de prontuários médicos e laboratoriais do Departamento de Oftalmologia da Universidade Federal de São Paulo, incluindo todos os pacientes com ceratite fúngica comprovada por cultura no período de outubro de 2012 a outubro de 2017. Resultados: Foram realizadas 2260 solicitações de testes microbiológicos. Destas, 140 amostras apresentaram culturas positivas para fungos, e 66 pacientes foram acompanhados em nosso serviço. Quarenta e cinco pacientes (68,2%) eram do sexo masculino, e a média de idade foi de 48,06 (± 17,39) anos. Fusarium spp. foi o fungo mais freqüentemente isolado (32 casos; 48,5%), seguido por Candida parapsilosis (12 casos; 18,2%). Trinta e quatro pacientes (51,5%) foram submetidos à injeção intracameral de anfotericina B (5 µg por 0,1 ml). Destes, 11 pacientes (32,3%) tiveram a infecção erradicada. Nos outros 23 pacientes (67,7%), o transplante terapêutico foi necessário. Nenhuma complicação relacionada à injeção intracameral de anfotericina B foi observada neste estudo. No total, 43 pacientes (65,1%) evoluíram para transplante terapêutico, e 3 pacientes (4,5%) foram submetidos à evisceração ou enucleação. Cinquenta e três pacientes (80,3%) apresentaram acuidade visual final pior que 20/200. Conclusões: Apesar dos diversos medicamentos antifúngicos atuais e vias de administração, o tratamento das ceratites fúngicas permanece desafiador. O atraso no início do tratamento adequado pode justificar o desfecho clínico desfavorável de grande parte dos pacientes. A injeção intracameral de anfotericina B mostrou-se uma alternativa terapêutica segura para ceratites fúngicas refratárias. Mas outras estratégias de tratamento devem ser formuladas, visando melhorar os resultados visuais dos pacientes.

ABSTRACT

ABSTRACT Purpose: To compare the impact of ocular changes between systemic treatment with doxycycline and low-dose oral isotretinoin in patients with moderate-to-severe papulopustular rosacea. Methods: Patients were randomized to receive either isotretinoin 0.3-0.4 mg/kg (group A) or doxycycline 100 mg/day (group B) for 16 weeks. Ocular symptoms were searched and evaluated, including best-corrected visual acuity (BCVA), Schirmer test, breakup time, rose bengal staining score, and meibomian gland dysfunction grading. The patients were retested at the end of treatment. Results: The present study included 39 patients (30 females and 9 males). Best-corrected visual acuity was > 20/30 in >90% of patients in both groups and did not change after treatment. After treatment, improvement in ocular symptoms and meibomian gland dysfunction was more pronounced in group B (p<0.05); the other parameters did not reach statistical significance. Conclusion: Doxycycline improved meibomian gland dysfunction, ocular symptoms, and ocular surface in patients with rosacea. Even though some patients experienced worsening meibomian gland dysfunction and symptoms, no subject experienced any serious complications after administration of low-dose isotretinoin.


RESUMO Objetivos: Comparar o impacto das alterações oculares entre o tratamento sistêmico de doxiciclina e isotretinoína em baixa dosagem em pacientes com rosácea papulopustulosa moderada a grave. Métodos: Os pacientes form randomizados para receber isotretinoína 0,3 a 0,4 mg/kg (grupo A) ou doxiciclina 100mg/dia (grupo B) por 16 semanas. Os sintomas oculares foram pesquisados e avaliados, incluindo melhor acuidade visual corrigida, teste de Schirmer, tempo de ruptura do filme lacrimal, coloração de rosa bengala e graduação da disfunção de glândula de Meibomius. Os pacientes foram novamente testados no final do tratamento. Resultados: O presente estudo incluiu 39 pacientes (30 mulheres e 9 homens). A melhor acuidade visual corrigida foi >20/30 em >90% dos pacientes em ambos os grupos e não se alterou após o tratamento. A melhora dos sintomas oculares e da disfunção de glândula de Meibomius foi mais pronunciada no grupo B (p<0,05) após o tratamento; as demais variáveis não atingiram significância estatística. Conclusão: A doxiciclina melhorou a disfunção de glândula de Meibomius, os sintomas oculares e a superfície ocular de pa cientes com rosácea. Mesmo que alguns pacientes tenham piorado a disfunção e os sintomas da glândula de Meibomius, nenhum indivíduo apresentou complicações graves após a admi nistração de baixas doses de isotretinoína.

ABSTRACT

ABSTRACT Objective: Herpes Zoster Ophthalmicus (HZO) is caused by varicella-zoster virus (VZV) and commonly affects elderly or immunocompromised patients. It has the potential to generate severe complications such as corneal ulcers, uveitis, retinal necrosis and post herpetic neuralgia. This study aimed to evaluate patients at the acute onset of the disease and describe their clinical profile and ophthalmologic findings. Methods: A cross-sectional study was performed from March 2014 to October 2015. All consecutive patients with the diagnosis of acute HZO (at a vesicle, pustule or crust stage) were enrolled and submitted to an ophthalmologic exam that included ectoscopy, best corrected visual acuity, corneal sensitivity test, slit-lamp examination, Goldmann applanation tonometry and funduscopic examination. Results: Nineteen patients were included. The mean age was 71 years old, ranging from 52 to 88. Ten patients had high blood pressure (52.6%) and nine (47.3%) had diabetes. Visual acuity lowered in comparison to the fellow eye in eleven patients (57%), ranging from one to six lines of vision, due mostly to epithelial keratitis and ocular discharge. Intraocular pressure (IOP) did not varied in most cases compared to the fellow eye. Hutchinson's sign (HS) was present in seven (36%) patients. The correlation between HS and anterior chamber reaction as well as decreased corneal sensitivity was statistically significant with Fisher's test of 0.009 and 0.029 respectively (p<0.05). Conclusion: The clinical profile of our patients was elderly patients with a higher rate of diabetes. Correlation between Hutchinson's sign and anterior chamber reaction as well as decrease in corneal sensitivity was significant. High intraocular pressure or posterior segment complications were not found in any cases.


RESUMO Objetivos: Herpes Zoster Oftálmico (HZO) é uma doença causada pelo vírus varicella-zoster que comumente afeta idosos ou doentes imunossuprimidos, com potencial para gerar graves comorbidades oculares, incluindo úlceras corneanas, uveíte, necrose retiniana e neuralgia pós-herpética. O objetivo deste estudo foi avaliar estes pacientes na forma aguda da doença e descrever seu perfil clínico e achados oftalmológicos. Métodos: Um estudo transversal foi realizado entre março de 2014 e outubro de 2015. Todos os pacientes consecutivos com o diagnóstico de HZO (na forma vesicular, pustulosa ou crostosa) foram incluídos e submetidos ao exame oftalmológico que incluiu ectoscopia, melhor acuidade visual corrigida, teste de sensibilidade corneana, biomicroscopia, tonometria de aplanação de Goldmann e fundoscopia. Resultados: Dezenove pacientes foram incluídos. A idade média foi de 71 anos. Dez (52,6%) pacientes relataram hipertensão arterial sistêmica e nove (47,3%) diabetes mellitus. A acuidade visual do olho acometido se encontrou abaixo do olho contra lateral em 57% dos casos, variando entre uma a seis linhas de visão. A pressão intraocular não variou na maioria dos casos em comparação com o olho contralateral. O sinal de Hutchinson estava presente em sete (36%) pacientes. A correlação entre este sinal e a presença tanto de reação de câmara anterior quanto de hipoestesia corneana foi positiva estatisticamente, com teste exato de Fisher de 0,009 e 0,029 respectivamente (p<0,05). Conclusão: Idosos com uma prevalência elevada de diabetes mellitus representaram o perfil clínico dos pacientes deste estudo. A correlação entre o sinal de Hutchinson e reação de câmara anterior, bem como daquele com hipoestesia corneana foi estatisticamente significativa. Não foi identificado nenhum caso de hipertensão ocular ou complicações de segmento posterior.

ABSTRACT

Abstract Objetive: To evaluate the association between sympathetic nervous system activity and blood pressure variability with central serous chorioretinopathy (CSC). Methods: We performed an individual, observational, and cross-sectional study involving 11 patients with CSC and 16 healthy individuals in similar age range. Participants underwent spectral power analysis of heart rate variability (HRV) at the Hypertension Department of Heart Institute at the University of São Paulo. Results: We demonstrated sympathetic activity predominance in CSC group and found that the LF (low frequency) of heart rate variability was significantly higher in this group (p = 0.04). when compared to control group. The CSC group's mean LF / HF (high frequency) ratio was higher than the control group but was not statistically significant (p = 0.2). Blood pressure variability was higher in CSC patients than in normal patients (p = 0.055), whereas heart rate variability was lower in these patients when compared to normal patients, although no statistical significance was found (p = 0.2). Spontaneous baroreflex function was significantly reduced in patients with CSC when compared to healthy individuals (p = 0.04). Conclusion: Autonomic dysfunction and a predominance of sympathetic modulation were observed in CSC patients.


Resumo Objetivo: Avaliar a associação entre a atividade do sistema nervoso simpático e a variabilidade da pressão arterial com a coriorretinopatia serosa central (CSC). Métodos: Estudo individuado, observacional e transversal envolvendo 11 pacientes com CSC e 16 indivíduos saudáveis de idade semelhante. Os participantes foram submetidos à análise de poder espectral da variabilidade da freqüência cardíaca no Departamento de Hipertensão do Instituto do Coração da Universidade de São Paulo. Resultados: Observamos o predomínio da atividade simpática no grupo com CSC, evidenciado pelo LF da variabilidade da freqüência cardíaca significativamente maior neste grupo (P = 0.04) quando comparado ao grupo controle. A média da relação LF / HF e a variabilidade da pressão arterial foram maiores nos pacientes com CSC do que nos pacientes normais (P = 0,2 e P = 0,055, respectivamente), enquanto a variabilidade da freqüência cardíaca foi menor nesses pacientes quando comparados aos pacientes normais (P = 0,2), embora não tenha sido encontrada significância estatística. A função barorreflexa espontânea também foi significativamente reduzida nos pacientes com CSC quando comparados aos indivíduos saudáveis (P= 0,04). Conclusão: Concluímos que há sinais de disfunção autonômica e predomínio da modulação simpática nos pacientes com CSC.

ABSTRACT

Que significados podem ser evidenciados em discursos de participantes de Conferências Municipais de Saúde acerca de tais eventos, seus processos decisórios e decorrências? Para analisar tais discursos práticos, referidos a eventos ocorridos em seis municípios do Ceará em 2007, realizou-se estudo de casos múltiplos, a partir de análise documental, entrevistas e grupos focais, com análise hermenêutica e dialética. Sobre as ocorrências dos eventos, evidenciam-se as oportunidades de expressão e mobilização de alguns grupos de interesses por demandas específicas, em cenários de interlocução competitiva e busca de mediações políticas visando eficácia simbólica eventual. Dentre as decorrências a partir das decisões deliberadas, destacam-se discursos sobre a negligência de governos municipais na incorporação dessas demandas em suas agendas políticas e na implantação de estratégias institucionais correspondentes. Como, também, a ausência de monitoramento a fim por parte dos respectivos Conselhos Municipais de Saúde.


What can be elicited from the discourse analysis of Municipal Health Conferences attendees regarding these meetings, its decision-making processes and results? This is a multiple case study of events that took place in six towns in the State of Ceará (Northeast of Brazil) in 2007, based on documental review, interviews and focus groups, with a hermeneutics and dialectic analysis. Throughout these meetings, there are evidences of the voice and the advocacy of groups with specific requests, under a landscape of competitive dialogue and the search of political mediations pursuing symbolical effectiveness. From the decision-making process point of view, the more relevant elements are the statements concerning the negligence of municipal governments on incorporating these resolutions on their political agenda and its corresponding institutional implantation strategies, as well as the absence of supervision by the Municipal Health Councils.


¿Qué significados pueden destacarse en los discursos de participantes de las Conferencias Municipales de Salud? Se analizaron conferencias realizadas en el Noreste de Brasil durante el año 2007. Este fue un estudio de múltiples casos, de fundamentación teórica hermenéutica y dialéctica, basado en técnicas de análisis documental, entrevistas y grupos focales. En las conferencias se destacaron la posibilidad de expresión y movilización de algunos grupos de intereses por demandas específicas, escenarios de interlocución competitiva y búsqueda de mediaciones políticas orientadas para la obtención de cierta eficacia simbólica eventual. Sobre las consecuencias de las decisiones deliberadas, se destacaron ciertos discursos sobre la negligencia de los gobiernos municipales en la incorporación de estas demandas en sus agendas políticas, así como en el despliegue de estrategias institucionales correspondientes. También se reveló la ausencia de monitoreo por parte de los respectivos Consejos Municipales de Salud.
