INTRAVITREAL INJECTIONS OF ZIV-AFLIBERCEPT FOR DIABETIC MACULAR EDEMA: A Pilot Study.

PURPOSE: Diabetic macular edema is the leading cause of blindness in young adults in developed countries. Beyond metabolic control, several therapies have been studied such as laser treatment and intravitreal injections of corticosteroids or anti-vascular endothelial growth factor drugs. In terms of public health the long-term treatment with the current available drugs is very expensive and new therapies with the same or better effect should be investigated. This study sought to evaluate the efficacy and safety of intravitreal injections of ziv-aflibercept for the treatment of diabetic macular edema. METHODS: Seven consecutive patients with diabetic macular edema were enrolled. A complete examination, including full-field electroretinography, visual acuity, central retinal thickness, and evaluation of systemic and ocular complications, was performed before and at 24 weeks after intravitreal injections of ziv-aflibercept. The seven patients were submitted to six consecutive intravitreal injections of ziv-aflibercept with a 4-week interval. RESULTS: No significant differences were found in the amplitude or implicit time of any electroretinography component after intravitreal injections of ziv-aflibercept, and no systemic or ocular complication was observed. The improvement of visual acuity was significant at 24 weeks (P < 0.05). The central retinal thickness significantly decreased during the course of 24 weeks. CONCLUSION: Intravitreal injections of ziv-aflibercept seem to be a safe and effective treatment option for diabetic macular edema.

MACULAR HOLE ASSOCIATED WITH TOXOPLASMOSIS: A SURGICAL CASE SERIES.

PURPOSE: There are currently limited data addressing the surgical outcomes of pars plana vitrectomy (PPV) in toxoplasmosis-related macular hole (tMH). We aim to report and discuss safety and efficacy of PPV for tMH. METHODS: Surgical case series (n = 11), with minimum postoperative follow-up time of 6 months. Consecutive patients who underwent PPV for tMH from 2013 to 2016 were included. Indications for surgery were: visual acuity ≥ 0.6 logarithm of the minimum angle of resolution (Snellen 20/80 or less), no intraocular inflammation for more than 6 months, extrafoveal toxoplasmosis scar, elevated tMH borders on optical coherence tomography, and patient agreement with surgery. Surgery was performed-PPV with epiretinal (if present) and internal limiting membrane peeling. Safety and efficacy of PPV for tMH were addressed by evaluating: 1) surgery-related complications and 2) visual acuity improvement. RESULTS: A total of 11 patients (6 male), with a mean age of 33.2 ± 11.0 years were studied. Mean preoperative best-corrected visual acuity significantly improved from 1.10 ± 0.24 (Snellen 20/252) to 0.43 ± 0.18 logarithm of the minimum angle of resolution (Snellen 20/54) at last follow-up visit (P < 0.01). The rate of visual acuity improvement (i.e., a gain of at least three lines) and tMH closure was 100% for both. The only reported surgery-related complication was cataract in one case. CONCLUSION: Our results suggest that PPV is a safe and effective option in tMH cases. A controlled, longitudinal study would contribute to confirm these findings.

INTRAVITREAL INJECTIONS OF ZIV-AFLIBERCEPT FOR THE TREATMENT OF A PATIENT WITH MACULAR EDEMA SECONDARY TO BRANCH RETINAL VEIN OCCLUSION.

PURPOSE: To describe the visual, tomographic, and electroretinographic findings in a patient with macular edema secondary to branch retinal vein occlusion who was submitted to three consecutive intravitreal injections of ziv-aflibercept. METHODS: The patient underwent a complete ophthalmic examination, as well as optical coherence tomography and full-field electroretinography at baseline and 90 days after the first injection. RESULTS: The best-corrected visual acuity improved from 20/400 to 20/40, and the central retinal thickness decreased from 791 µm to 198 µm after three consecutive intravitreal injections of ziv-aflibercept. Full-field electroretinography showed an increase in cone amplitude and decrease in rod amplitude. No adverse side effects were observed after injections. CONCLUSION: Intravitreal injections of ziv-aflibercept showed both effectiveness and safety in the treatment of a patient with macular edema secondary to branch retinal vein occlusion. The observed anatomic (by ophthalmic examination, optical coherence tomography) and functional (best-corrected visual acuity, full-field electroretinography) improvements and lack of serious adverse side effects demonstrates the potential of intravitreal injections of ziv-aflibercept for the treatment of macular edema secondary to branch retinal vein occlusion.

Intravitreal Angiostrongylus cantonensis: first case report in South America.

This study reports the first case of intravitreal angiostrongyliasis in South America treated with posterior worm removal via pars plana vitrectomy. This was a retrospective, observational case study. Data from medical charts, wide-field digital imaging, ocular ultrasound, and visual evoked potential studies were reviewed. A 20-month-old boy presented with eosinophilic meningitis and right eye exotropia. Polymerase chain reaction analysis of the cerebrospinal fluid showed a positive result for Angiostrongylus cantonensis. Fundus examination revealed a pale optic disc, subretinal tracks, vitreous opacities, peripheral tractional retinal detachment, and a dead worm in the vitreous cavity. The patient underwent pars plana vitrectomy with worm removal. This case report illustrates the first case of intravitreal angiostrongyliasis in South America, possibly related to the uncontrolled spread of an exotic invasive species of snail.

Preliminary study of rabbits as an animal model of mammalian eye transplantation and literature review / Estudo preliminar de coelhos como modelo animal para transplante de olho em mamíferos e revisão da literatura

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left eye was used as control group. Results: After optic nerve resection and anastomosis, stable ERG amplitude of the right eye was lost after 302 seconds in group 1 and after 296 seconds on group 2. Left eye kept longer stable ERG amplitude curves. Conclusions: The animal model of whole eye transplantation was effective in describing a novel technique to be used in rabbits, with success of the anatomic procedure. Further studies will clarify the best anastomosis methods and maintenance of function of the receptor organ. Translational relevance: this animal model of whole eye transplantation provides a novel perspective for blind patients and the research models, since we describe a novel mammal animal model. This model can be used as basis of a human model of whole eye transplantation in future studies.

RESUMO Objetivo: Descrever uma técnica cirúrgica inovadora para transplante de olho em um modelo animal em coelhos. Métodos: Seis coelhos machos com Dutch Belted foram submetidos à orbitotomia lateral do olho direito, com ampla exposição da anatomia retrobulbar, dissecção do cone muscular, exposição e secção distal do nervo óptico seguida de anastomose por vicryl (Grupo 1) ou cola de fibrina (Grupo 2). O registro da eletrorretinografia foi realizado antes da secção do nervo óptico e a cada 30 segundos após, para monitorar a função da retina. O olho esquerdo foi usado como grupo controle. Resultados: Após a ressecção do nervo óptico, a estabilidade da amplitude da eletrorretinografia foi perdida no olho direito após 302 segundos no Grupo 1 e após 296 segundos no Grupo 2. O olho esquerdo manteve eletrorretinografia estável por períodos mais longos. Conclusão: O modelo animal de transplante total de olho foi eficaz em descrever uma nova técnica cirúrgica para ser utilizada em laboratório com coelhos, com sucesso do procedimento anatômico. Novos estudos esclarecerão os melhores métodos de anastomose e manutenção da função do órgão receptor.

Non-alcoholic fatty liver disease (NAFLD) in different populations: A clinical and epidemiological study - sample of São José do Rio Preto.

INTRODUCTION: NAFLD is an heterogeneous condition that includes steatosis and non-alcoholic steatohepatitis (NASH), in the absence of significant alcohol consumption, reaching 30% of the population. The most common risk factors are: age, gender, ethnicity, diabetes mellitus (DM), obesity, predisposition, metabolic syndrome (MS), insulin resistance (IR), drugs, and polycystic ovary syndrome. OBJECTIVE: To describe the profile of patients with NAFLD seen at Hospital de Base of Rio Preto, in the state of São Paulo. METHOD: Patients with NAFLD were assessed, with medical and epidemiological data collected after informed consent. RESULTS: Of the 62 patients evaluated, 76% were women, 73% Caucasians, and 71% were aged between 50 and 69 years and had no symptoms. Ultrasonography results showed steatosis in 84%. NASH was diagnosed in 61% of the sample. 21 patients underwent liver biopsy, of which 36% had cirrhosis, 1 had liver cancer, and 1 pure steatosis (5% each). Risk factors were found in 70% of patients with metabolic syndrome, 87% with increased waist circumference, 63% with dyslipidemia, 61% (n=38) with high blood pressure (HBP), 28% with DM, 52% physically inactive, and 44% with insulin resistance (IR) (HOMA> 3.5). There was an association between IR and NASH (p=0.013), IR and obesity (p=0.027), IR and MS (p=0.006), and MS and steatosis on medical ultrasound (USG) (p=0.014). CONCLUSION: The most frequent risk factors were MS and its variables: increased waist circumference, dyslipidemia and HBP. This underscores the importance of metabolic control in NAFLD and confirms its role as the hepatic component of metabolic syndrome.

Comparison of 3 different anesthetic approaches for intravitreal injections: a prospective randomized trial.

PURPOSE: To compare the anesthetic effectiveness of topical proparacaine drops, subconjunctival lidocaine, and 2% lidocaine gel. METHODS: Ninety-two patients undergoing intravitreal injections were randomized to 1 of 3 groups: proparacaine 0.5% drops (Group Drops), proparacaine 0.5% drops plus subconjunctival lidocaine (Group SC), or 2% lidocaine gel (Group Gel). Patients were asked to score their pain experience using a visual analog scale of 0 to 10 immediately following the injections and 10 min, 1 h, 6 h, and 24 h after the injections. Patients also graded the overall injection experience as Excellent, Very Good, Fair, Poor, or Awful. The physician evaluated the patients' eye movement during intravitreal injection on 3 levels: (0) none or minimal, (1) not compromising the injection, and (2) compromising the injection. RESULTS: The patients in Group Drops had the worst mean pain scores during the injection and 10 min after, with the highest occurrence of movements compromising the procedure (Grade 2; 38.7%). The patients in Group SC had a higher percentage of good experiences (37.9%) but a higher incidence of chemosis (16.7%). The patients in Group Gel had similar overall pain scores to Group Drops patients but a higher incidence of keratitis (19.4%). There was no statistically significant correlation between the use of aspirin or anticoagulants and the occurrence of hyperemia or hyposphagma. CONCLUSION: Subconjunctival lidocaine was most effective in preventing pain and eye movements during intravitreal injections. Although 2% lidocaine gel produced a good overall experience for the patients, the incidence of keratitis was very high (19.4%). Therefore, we do not recommend 2% lidocaine gel as the first anesthetic choice for intravitreal injections. There is no evidence to suspend the use of aspirin or other anticoagulants drugs prior to intravitreal injections.

RESUMO O objetivo deste estudo foi relatar o primeiro caso na América do Sul de angiostrongilíase intravítrea tratada com vitrectomia posterior via pars plana e remoção do verme. Este foi um relato de caso observacional. O prontuário médico, sistema de imagem digital de campo amplo, ultrassonografia ocular, e potenciais evocados visuais foram revistos. Um menino de 1 ano e 8 meses de idade manifestou meningite eosinofílica e exotropia olho direito. A análise de PCR do liquor foi positiva para Angiostrongylus cantonensis. O exame de fundo de olho revelou disco óptico pálido, faixas sub-retinianas, opacidades vítreas, descolamento de retina tracional periférico e um verme morto no vítreo. O paciente foi submetido a vitrectomia posterior via pars plana com a remoção do verme. Concluindo, este é o primeiro relato de caso de angiostrongilíase intravítrea na América do Sul, possivelmente relacionado com a disseminação de uma espécie de lesma exótica neste continente.

Coroidopatia no lúpus eritematoso sistêmico / Choroidopathy in systemic lupus erythematosus

Resumo O Lúpus Eritematoso sistêmico (LES) é uma doença autoimune que pode afetar o olho de diversas formas. A coroidopatia lúpica é rara e apresenta-se com descolamento seroso de retina, descolamento do epitélio pigmentar da retina (EPR) e epiteliopatia pigmentar. A maioria dos casos está associada à atividade sistêmica da doença, podendo ser considerada um fator de gravidade e necessidade de imunossupressão intensa. Geralmente apresenta bom prognóstico visual com o tratamento adequado do LES, apesar de alguns casos evoluírem com danos irreversíveis na retina externa e EPR. Descrevemos um caso de coroidopatia secundaria ao LES com atividade multisistêmica com boa evolução após tratamento clínico com imunossupressão sistêmica.

Abstract Systemic lupus erythematosus (SLE) is an autoimmune disease in which can affect the eye in different ways. Lupus choroidopathy is rare and include retinal pigment epithelium (RPE) detachment and/or serous retinal detachment and pigment epitheliopathy. Most cases are associated with systemic disease activity and can be considered a factor of gravity and need for intense immunosuppression. Usually has good visual prognosis with proper treatment of SLE, although some cases may have irreversible damage to the outer retina and RPE. We describe a case of choroidopathy secondary to SLE during its multisystem activity with good clinical outcome after treatment with systemic immunosuppression.

RESUMO Introdução: a doença hepática gordurosa não alcoólica (DHGNA) é uma condição heterogênea que inclui esteatose e esteato-hepatite não alcoólica (NASH), na ausência de consumo significante de álcool, podendo atingir 30% da população. Fatores de risco mais comuns são idade, gênero, etnia, diabetes mellitus (DM), obesidade, predisposição, síndrome matabólica (SM), resistência à insulina (RI), drogas e síndrome do ovário policístico. Objetivo: descrever o perfil de portadores de DHGNA assistidos no Hospital de Base de São José do Rio Preto, SP. Método: foram avaliados pacientes com DHGNA e coletados dados clínico-epidemiológicos, após consentimento informado. Resultados: dos 62 pacientes estudados, houve predomínio de mulheres (76%), caucasoides (73%), idade entre a quinta e sexta décadas e assintomáticos (71%). Exame de ultrassonografia (US) mostrou esteatose em 84%. NASH foi diagnosticada em 61% da casuística. Em 21 pacientes, biópsia hepática mostrou cirrose em 36% e câncer de fígado e esteatose pura em um paciente (5%) cada. Dos fatores de risco, 70% dos pacientes apresentavam SM; 87%, cintura abdominal alterada; 63%, dislipidemia; 61% (n=38), hipertensão arterial sistêmica (HAS); 28%, DM; 52%, sedentarismo, e em 44% encontrou-se RI (HOMA>3,5). Houve associação entre RI e NASH (p=0,013), RI e obesidade (p=0,027), RI e SM (p=0,006), SM e esteatose à US (p=0,014). Conclusão: os fatores de risco mais frequentes foram SM e suas variáveis (cintura abdominal aumentada, dislipidemia e HAS), o que ressalta a importância do controle metabólico na DHGNA e corrobora o seu papel como componente hepático da SM.

Objetivo: Comparar a eficácia anestésica entre proparacaína tópica, lidocaína subconjuntival e lidocaína gel a 2%. Métodos: Noventa e dois pacientes em tratamento com injeções intravítreas foram randomizados para um de três grupos: proparacaína 0,5% gotas (Grupo gotas), proparacaína 0,5% gotas seguida de lidocaína subconjuntival (Grupo SC), ou lidocaína gel a 2%. (Grupo Gel). Os pacientes foram orientados a graduar a sua experiência de dor por uma escala visual analógica, numa escala de 0 a 10, imediatamente após as injeções, bem como 10 minutos, 1 hora, 6 horas e 24 horas após. Os pacientes também classificaram a experiência global de injeção como excelente, muito boa, regular, ruim ou horrível. O médico avaliou o movimento do olho do paciente durante a injeção intravítrea em três níveis: nenhuma ou mínima (0), não comprometendo a injeção (1), comprometendo a injeção (2). Resultados: Os pacientes do grupo gotas apresentaram uma graduação média de dor pior durante a injeção e 10 minutos após, com maior ocorrência de movimentos comprometendo a injeção (grau 2) (38,7%). Os pacientes do grupo SC, apresentaram maior percentual de boa experiência durante o procedimento (37,9%) e maior ocorrência de quemose (16,7%). Os pacientes do grupo Gel apresentaram escore de dor geral semelhante ao grupo Gotas e maior incidência de ceratite (19,4%). Não houve correlação estatisticamente significativa com o uso de aspirina ou anticoagulantes e a ocorrência de hiperemia ou hiposfagma. Conclusão: Lidocaína subconjuntival foi mais eficaz na prevenção da dor durante injeção intravítrea com movimentação ocular mínima. Embora os pacientes do grupo lidocaína gel a 2% tenham apresentado uma boa experiência, consideramos a incidência ceratite muito elevada (19,4%) e não recomendamos lidocaína gel a 2% como a primeira escolha como anestésico para injeções intravítreas. Não há evidência para a suspensão do uso de aspirina ou drogas anti-coagulantes em pacientes ...

Prevalência de obesidade em crianças e adolescentes com diabetes melito tipo 1 / Prevalence of obesity in children and adolescents with type 1 diabetes mellitus

OBJETIVO: Conhecer a prevalência de obesidade e sua distribuição por sexo e idade em pacientes com diabetes melito tipo 1 (DM1), em acompanhamento em Serviço de Endocrinologia Pediátrica. MÉTODOS: Estudo transversal descritivo de pacientes em acompanhamento no Serviço de Endocrinologia Pediátrica do Hospital de Base de São José do Rio Preto, avaliando as seguintes variáveis: sexo, idade, dose e número de aplicações diárias de insulina, hemoglobina glicada (HbA1c), peso, estatura e índice de massa corpórea (IMC). A definição de sobrepeso e obesidade baseou-se nas curvas de IMC para a idade do Centers for Disease Control and Prevention (CDC, 2000). RESULTADOS: Foram incluídos 77 portadores de DM1 (44 meninas e 33 meninos) com idade entre três e 18 anos (média: 13,4). A determinação de HbA1c variou de 4,1 a 10,6 por cento (média: 7,7 por cento) e o IMC, de 15,1 a 28,6 kg/m² (média: 23,2). Conforme critérios do CDC, 8 por cento dos pacientes (três meninas e três meninos) apresentavam obesidade e 8 por cento (duas meninas e quatro meninos), sobrepeso. CONCLUSÕES: Nesta casuística de pacientes diabéticos, a prevalência de sobrepeso e obesidade não se mostrou diferente de populações não diabéticas.

OBJECTIVE: To describe the prevalence of obesity according to gender and age in patients with type 1 diabetes mellitus of a pediatric endocrinology follow-up clinic. METHODS: This cross-sectional descriptive study enrolled patients of the follow-up clinic of the Pediatric Endocrinology Unit of Hospital de Base of São José do Rio Preto, São Paulo, Brazil. The following data were collected: gender, age, insulin dosage, glycated hemoglobin (HbA1c), weight, height and body mass index (BMI). The cutoff criteria for overweight and obesity were based on BMI-for-age growth charts of the Centers for Disease Control and Prevention (CDC, 2000). RESULTS: 77 patients with type 1 diabetes mellitus were included (44 females and 33 males), with three to 18 years old (mean: 13.4). The value of HbA1c varied from 4.1 to 10.6 percent (mean: 7.7 percent) and the BMI ranged from 15.1 to 28.6 kg/m² (average: 23.2). Based on BMI charts, 8 percent (three girls and three boys) were obese and 8 percent (two girls and four boys) had overweight. CONCLUSION: Compared to the prevalence of obesity and overweight in non-diabetic pediatric population, the presence of these nutritional disturbances in the studied children was not significantly different.
