Toxoplasmosis outbreak in São Paulo, Brazil: Epidemiology and visual outcome

ABSTRACT Purpose: To describe a 2019 acute toxoplasmosis outbreak in the city of São Paulo, Brazil, and to evaluate the laboratory serological profile for toxoplasmosis for three consecutive years. The ophthalmological manifestations of the patients involved in the outbreak were also studied. Methods: A cross-sectional descriptive study of a toxoplasmosis outbreak in São Paulo, Brazil, between February and May 2019. Epidemiological data were described, as were the observed ocular manifestations. As part of this study the number of patients with positive IgM toxoplasmosis serology was obtained from a large laboratory network (DASA) for three consecutive years, including the year of the outbreak (2018, 2019, 2020). Results: Eighty-three individuals were identified in the outbreak and two clusters were studied. The clinical picture of at least 77% of the patients, the epidemiological analysis, and the short incubation period (5-8 days) suggested contamination by oocysts. Serological laboratory data analysis revealed an increase of positive toxoplasmosis IgM in 2019 of 73% compared to the previous year. Ophthalmological examination revealed that at least 4.8% of the patients developed toxoplasmic retinochoroiditis, none of whom had been treated during the acute systemic disease. Conclusion: Our findings indicate vegetable contamination as the possible source of this outbreak, a high prevalence of toxoplasmosis in São Paulo during the outbreak period, and a drop in the number of tests during the COVID-19 pandemic. Retinochoroiditis was observed in at least 4.8% of the cases. We confirm the need to implement effective means for the prevention, diagnosis, and treatment of the disease. This may involve raising awareness among the population of the importance of vegetable hygiene, and improved quality control of food and water.

Clinical and imaging characteristics of outer retinal folds in eyes with retinitis

Purpose: To describe clinical and imaging characteristics of the outer retinal folds (ORF) in cases of retinitis, retinochoroiditis, and chorioretinitis. Methods: Retrospective review of retinitis cases with presence of ORFs either at presentation or during follow up. Results: ORFs were seen adjacent to retinitis lesions in 16 eyes of 14 cases (retinitis post-febrile illness n = 10, toxoplasma retinochoroiditis n = 2, fungal chorioretinitis n = 2) either at presentation (n = 2) or during follow up (n = 14). Optical coherence tomography (OCT) appearance was outer retinal vertical stout lesions involving ellipsoid, external limiting membrane, and outer nuclear layer. All the cases had a presence of past or concurrent subretinal fluid and/or subretinal hyperreflective material when ORF was seen. ORF resolved with variable outer retinal atrophy over a mean period of 2.86 months. Conclusion: ORF is observed in cases of retinitis with subretinal fluid either at presentation or during resolution. It is not specific to any etiological disease. Differentiation of this sign from vertical outer retinal stripes in viral retinitis on OCT is important to avoid misinterpretation.

RESUMEN El propósito del presente estudio fue describir las características epidemiológicas, clínicas, y terapéuticas de pacientes con diagnóstico de toxoplasmosis congénita (TC) con enfermedad neurológica severa. Se revisaron las historias clínicas de los pacientes menores de 1 año con serología IgM positiva para Toxoplasma gondii y compromiso encefálico, ocular y/o auditivo. El estudio se realizó en el Instituto Nacional de Salud del Niño San Borja (INSN-SB) en Lima, Perú. Se evaluaron a 21 pacientes con diagnóstico de TC, el 57,1% fueron del sexo femenino y la mediana de edad al momento del diagnóstico fue 3,1 meses (RIC: 1,7-7,3). Las principales manifestaciones del sistema nervioso central fueron hidrocefalia (76,2%), calcificaciones intracraneales (52,4%), microcefalia (42,9%), y convulsiones (25,6%); la manifestación ocular más frecuente fue la coriorretinitis (38,1%). En conclusión, 64% de los casos de TC tuvieron una o más manifestaciones de enfermedad neurológica severa.

ABSTRACT The aim of this study was to describe the epidemiological, clinical, and therapeutic characteristics of patients diagnosed with congenital toxoplasmosis (CT) with severe neurological disease. We reviewed the medical records of patients under 1 year of age with positive IgM test for Toxoplasma gondii and brain, eye, and/or hearing involvement. This study was carried out at the Instituto Nacional de Salud del Niño San Borja (INSNSB), Lima, Peru. Twenty-one patients diagnosed with CT were evaluated; 57.1% were female, and the median age at diagnosis was 3.1 months (IQR: 1.7-7.3). The main central nervous system manifestations were hydrocephalus (76.2%), intracranial calcifications (52.4%), microcephaly (42.9%), and convulsions (25.6%); the most frequent ocular manifestation was chorioretinitis (38.1%). In conclusion, 64% of CT cases had one or more manifestations of severe neurological disease.

Simultaneous ocular and osseous syphilis: a case report / Sífilis com envolvimentos ocular e ósseo simultâneos: um relato de caso

ABSTRACT Syphilis is a reemerging and potentially serious disease. Owing to its ubiquity and pleomorphism, it is called "the great imitator". We report the case of a young woman with secondary syphilis who presented with bilateral acute syphilitic posterior placoid chorioretinopathy along with a syphilitic skull periostitis. A pachymeningeal enhancement was observed on magnetic resonance imaging, but we believe it was an extension of the bone process rather than a meningitis itself on the basis of the normal cerebrospinal fluid analysis results. Treatment with intravenous crystalline penicillin resulted in complete resolution of the signs, symptoms, and imaging findings. Secondary syphilis is the stage with the highest bacteremia and the highest transmissibility, presenting mainly with mucocutaneous disorders and, less frequently, with involvement of other organs. High suspicion and a pragmatic approach are essential to the diagnosis because this disease can affect several organs, as in the present case, in which the eyes, bones, and skin were affected.

RESUMO A sífilis é uma doença reemergente e potencialmente grave. Por sua onipresença e pleomorfismo, é denominada "grande imitadora". Relatamos caso de paciente jovem com sífilis secundária, que se apresentou com coriorretinopatia placóide sifilítica posterior aguda bilateral, simultaneamente a periostite craniana sifilítica. A despeito de realce paquimeníngeo observado na ressonância magnética, acreditamos que este tenha sido uma extensão do processo ósseo e não, uma meningite em si, uma vez que o exame do líquido cefalorraquidiano estava completamente normal. Tratamento com penicilina cristalina intravenosa resultou em completa resolução dos sinais, sintomas e achados de imagem. A sífilis secundária é o estágio de maior bacteremia e maior transmissibilidade da doença, apresentando-se principalmente com quadros mucocutâneos, mas também, menos frequentemente, com envolvimento de outros órgãos. Elevada suspeição e uma abordagem pragmática são necessárias para o diagnóstico, uma vez que essa doença pode afetar vários órgãos, como no caso relatado, em que foram acometidos olhos, ossos e pele.

Miositis por Bartonella henselae: caso clínico en una adolescente / Bartonella henselae myositis: case report in an adolescent

La miositis de origen vírico o bacteriano es frecuente en la edad pediátrica. Causa dolor muscular y debilidad, con fiebre y malestar general. Una causa es la infección por Bartonella henselae, bacteria implicada en la enfermedad por arañazo de gato que, a veces, causa afectación multisistémica. Se presenta el caso de una adolescente que acudió al servicio de urgencias por mialgia intensa, malestar, adelgazamiento y esplenomegalia. En el labortorio se observaron parámetros inflamatorios elevados. Refería contacto con un gato. Entre los estudios realizados, la resonancia magnética (RM) de miembros inferiores mostró una imagen compatible con miositis inflamatoria bilateral. En la RM abdominal, se observaron tres lesiones esplénicas no detectadas previamente y el fondo de ojo mostraba una lesión compatible con oclusión arterial retiniana o vasculitis. Se indicó tratamiento antibiótico por vía intravenosa durante 21 días con cefotaxima y cloxacilina, tras los cuales desaparecieron los signos y síntomas, aunque los reactantes inflamatorios persistieron elevados. Con base en el cuadro clínico (miositis + coriorretinitis + absceso esplénico) se pensó en una posible infección por B. henselae y se inició tratamiento oral con azitromicina y rifampicina durante 14 días. Luego del tratamiento, los valores de laboratorio fueron normales, así como la RM de control, y se constató una IgG positiva para la bacteria

Infectious myositis, whether viral or bacterial, is frequent in pediatric age. It causes muscle pain and weakness, associated with fever and general malaise. One cause is Bartonella henselae, responsible for cat scratch disease, which sometimes causes systemic symptoms. We report the case of an adolescent who came to the emergency room with intense myalgia, malaise, weight loss and splenomegaly. Blood tests showed high inflammatory markers. She had been in touch with a cat. Studies were carried out including: lower limbs MRI suggestive of bilateral inflammatory myositis, abdominal MRI with three previously undetected splenic lesions and dilated fundus examination that showed possible retinal arterial occlusion or vasculitis. After 21 days of intravenous antibiotic therapy (cefotaxime + cloxaciline), she became asymptomatic, but inflammatory markers remained high. Suspecting Bartonella henselaeinfection (myositis + chorioretinitis + splenic abscess), oral azithromycin and rifampicin were prescribed for 14 days. Blood tests and control MRI became normal, and IgG was positive.

Tratamentos alternativos para toxoplasmose ocular: uma revisão integrativa / Alternative treatment of ocular toxoplasmosis: an integrative review

Introdução: A toxoplasmose é uma infecção de distribuição cosmopolita, tendo como um dos principais achados a toxoplasmose ocular. Contudo, existem divergências quanto à eficácia dos tratamentos atualmente propostos. Objetivos: Revisar na literatura científica os tratamentos recomendados para retinocoroidite/corioretinite toxoplásmica. Métodos: Foi realizada uma busca de artigos publicados nos bancos de dados MEDLINE e LILACS, utilizando os descritores "retinocoroidite", "toxoplasmose" e "tratamento", assim como as traduções para o inglês. Foram selecionados trabalhos publicados no período de 2010 a março de 2020. Obtiveram-se 612 resultados na busca, sendo 7 artigos elegíveis para avaliação integral. Os parâmetros analisados foram a melhora na acuidade visual corrigida, número de recorrências e efeitos adversos. Resultados: Todos os esquemas terapêuticos apresentaram melhora no valor da melhor acuidade visual corrigida, mas não foi evidenciado superioridade ao esquema gold standard ou ao placebo. A Trimetoprima e Sulfametoxazol apresentaram grande eficácia em evitar recorrência das lesões. O esquema tradicional (Pirimetamina, Sulfadiazina e Prednisolona) foi o único que apresentou efeitos adversos graves. Discussão: Nesta revisão, não foram encontradas evidências de que os tratamentos alternativos analisados são superiores ao esquema tradicional ou ao placebo quanto à melhora da acuidade visual. A Trimetoprima e Sulfametoxazol orais foram eficazes em evitar recorrência de novas lesões em um período de 3 anos. Recomenda-se sejam realizados novos ensaios clínicos randomizados com acompanhamento a longo prazo visando confirmar estas questões.

Introduction: Toxoplasmosis is a cosmopolitan infection, and one of the main findings is the ocular toxoplasmosis. However, there are disagreements regarding the effectiveness of the proposed treatments. Objectives: The aim of this article is to review the recommended treatments for toxoplasmic retinochoroiditis/chorioretinitis in the scientific literature. Methods: It was performed a search for articles published in the PubMed and LILACS databases, using the descriptors "retinochoroiditis", "toxoplasmosis" and "treatment", as well as the translation into Portuguese. There were included works published in the period from 2010 to March 2020. The initial research found 612 papers, and 7 articles were eligible for full evaluation. The parameters analyzed were the best corrected visual acuity (BCVA), number of recurrences and adverse effects. Results: All therapeutic regimens showed an improvement in BCVA value, but there was no evidence of superiority to the gold standard or placebo regimen. Trimethoprim and Sulfamethoxazole were highly effective in preventing recurrence of lesions. The traditional regimen (Pyrimethamine, Sulfadiazine and Prednisolone) was the only one that had serious adverse effects. Conclusion: In this review, no evidence was found that the alternative treatments analyzed are superior to the traditional regimen or to placebo in terms of improving visual acuity. Oral Trimethoprim and Sulfamethoxazole were effective in preventing recurrence of new lesions over a 3-year period. It is recommended that new randomized controlled trials with long-term follow-up be performed to confirm these issues.

Fulminant Toxoplasmic Chorioretinitis Following Intravitreal Dexamethasone Implantation

PURPOSE: To report a case of fulminant toxoplasmic chorioretinitis following intravitreal dexamethasone implantation monotherapy in a stabilized toxoplasmic chorioretinitis patient with initial treatment. CASE SUMMARY: A 60-year-old healthy female presented with decreased visual acuity in the left eye. On fundus examination, focal chorioretinitis and yellow-white infiltration were observed. Laboratory work-up, including blood chemistry, complete blood count, and serum serology, was negative; however, toxoplasmic chorioretinitis could not be ruled out. The primary lesion improved with antibiotics and prednisolone treatment. However, the patient did not come in for her follow-up visit, as she had already received an intravitreal dexamethasone implant for recurrent vitreous inflammation elsewhere. On her return, she presented with necrotic retinitis with extensive infiltration. She underwent diagnostic vitrectomy and implant removal. A diagnosis of toxoplasma antigen was confirmed by polymerase chain reaction analysis; the lesions stabilized after anti-toxoplasmic therapy. CONCLUSIONS: Intravitreal dexamethasone implant monotherapy with stabilized toxoplasmic chorioretinitis without systemic antibiotics can lead to fulminant toxoplasmic chorioretinitis and should be used with caution.

Coriorretinopatía esclopetaria manejada con vitrectomía pars plana temprana. Reporte de un caso / Chorioretinitis sclopetaria managed with early pars plana vitrectomy. Case report

Resumen Introducción La coriorretinopatía esclopetaria es una rara entidad resultante de un trauma por proyectil de alta velocidad que haya pasado adyacente o a través de la órbita, sin penetrar el globo ocular. Provoca daño coriorretiniano de espesor completo y pérdida visual. Objetivo Presentar un caso clínico de esta rara entidad, tratada de manera poco habitual, dados los hallazgos clínicos iniciales y con buen resultado final. Reporte de un caso Masculino de 42 años de edad, que refirió una fuerte detonación de arma de fuego cerca del globo ocular. Presentó baja visual los días posteriores y se diagnosticó hemovítreo; se realizó un ultrasonido ocular, el cual reportó desgarro retiniano, por lo que se realizó vitrectomía pars plana. Al final del seguimiento, se encontró con capacidad visual de cuenta dedos a 30 cm. Se realizaron estudios complementarios para documentar los hallazgos clínicos, presentando fractura coroidea con involucro macular. Se describe su seguimiento por cuatro semanas; se mantiene con estabilidad visual, sin complicaciones posteriores. Conclusiones Presentamos el caso de una coriorretinopatía esclopetaria, la cual está escasamente reportada. Hasta el momento, es el primer caso tratado con vitrectomía temprana sin complicaciones posteriores y estabilidad visual posterior.

Abstract Introduction Chorioretinitis sclopetaria is a rare entity resulting from trauma by a high-velocity projectile that passed adjacent or through the orbit without penetrating the eyeball. It causes full-thickness chorioretinal damage and visual loss. Objective To present a clinical case of the entity treated in an unusual way, with a good result. Case report 42 year-old male who mentioned a strong firearm detonation near the eyeball. Days later, he presented with visual loss, and hemovitreous was diagnosed. An ocular ultrasound was done, which reported retinal tear, so a pars plana vitrectomy was performed. At the end of the follow up, there was a visual ability to count fingers at 30 cm. Complementary studies were carried out to document the clinical findings, showing a choroidal fracture with macular involvement. Follow-up was carried up to four weeks after the intervention, without complications and with visual stability. Conclusions We present a case of chorioretinitis sclopetaria, which is scarcely reported; so far, this is the first case treated with early vitrectomy without later complications.

Recém-nascidos com risco de toxoplasmose congênita, revisão de 16 anos / Newborns at risk for congenital toxoplasmosis, review of 16 years

OBJETIVOS: Analisar os dados de gestações com risco de toxoplasmose congênita e investigar a evolução dos recém-nascidos, em um hospital de nível II em Portugal. MÉTODOS: Um estudo transversal retrospetivo incluiu recém-nascidos com risco de toxoplasmose congênita e suas mães, cujo parto ocorreu entre janeiro de 2000 e dezembro de 2015. Os critérios de inclusão foram mãe com soroconversão para toxoplasmose durante a gestação ou primeira amostra sérica com IgM e IgG específicas positivas. O diagnóstico de toxoplasmose congênita foi definido por IgM específica positiva ao nascimento e/ou reação em cadeia da polimerase positiva no líquido amniótico e/ou persistência de IgG específica até os 12 meses de vida. A toxoplasmose congênita foi definida como sintomática quando os achados clínicos foram atribuídos à doença. Os testes Qui-quadrado ou Exato de Fisher foram usados para testar associações entre variáveis, assumindo-se significado estatístico quando p<0,05. RESULTADOS: Ocorreram 39.585 nascimentos vivos no período em estudo e foram identificados 98 casos com risco de toxoplasmose congênita, dos quais 89 completaram o seguimento. A prevalência de IgG para T. gondii nas gestantes foi de 26% (intervalo de confiança [IC] 95% 24-27%). Foram confirmados 22 casos de toxoplasmose congênita (5,6 por 10.000 nascidos vivos, IC95% 3,5-8,5 por 10.000). Dos 22 recém-nascidos, 18 (82%, IC95% 61-93%) eram sintomáticos. Os achados clínicos mais frequentes foram calcificação intracraniana (64%), hepatomegalia e/ou elevação das transaminases (32%) e retinocoroidite (14%). As lesões cerebrais foram mais frequentes quando a infeção materna foi documentada no primeiro e segundo trimestres em comparação com o terceiro (p=0,018). Em 31 casos (35%), as gestantes foram tratadas desde o momento do diagnóstico até o parto com espiramicina, não se tendo encontrado diferenças relativamente à taxa de transmissão vertical ou ao aparecimento de manifestações clínicas entre os recém-nascidos de mães tratadas e não tratadas. CONCLUSÕES: A prevalência de toxoplasmose congênita foi superior à reportada em outros países da Europa. A prevalência de calcificações intracranianas foi maior do que a descrita na literatura, enquanto que a de retinocoroidite e estrabismo foi menor. As alterações cerebrais nos recém-nascidos foram mais frequentes nas infecções de primeiro e segundo trimestre. Não houve diferença na taxa de transmissão vertical e na ocorrência de manifestações clínicas entre os recém-nascidos cujas mães receberam espiramicina na gestação ou não receberam tratamento.

AIMS: To analyze the data on pregnancies with risk of congenital toxoplasmosis and to investigate the newborns' outcome, in a level II hospital in Portugal. METHODS: A cross-sectional retrospective study included newborns at risk for congenital toxoplasmosis and their mothers, whose delivery occurred between January 2000 and December 2015. The inclusion criteria were mother with seroconversion to toxoplasmosis during pregnancy or first serum sample with positive specific IgM and IgG. The diagnosis of congenital toxoplasmosis was defined by positive specific IgM at birth and/or polymerase chain reaction positive in amniotic fluid and/or persistence of specific IgG up to 12 months of life. Congenital toxoplasmosis was defined as symptomatic when clinical findings were attributed to the disease. Chi-square or Fisher's exact tests were used to test associations between variables, assuming statistical significance when p<0.05. RESULTS: There were 39,585 live births in the study period and 98 cases with risk of congenital toxoplasmosis were identified, of which 89 completed the follow-up. The prevalence of anti-T. gondii IgG in the pregnant women was 26% (95% confidence interval [CI] 24-27%). Twenty-two cases of congenital toxoplasmosis (5.6 per 10,000 live births, 95%CI 3.5-8.5 per 10,000) were confirmed. Of the 22 newborns, 18 (82%, 95%CI 61-93%) were symptomatic. The most frequent clinical findings were intracranial calcification (64%), hepatomegaly and / or elevation of transaminases (32%) and retinochoroiditis (14%). Cerebral lesions were more frequent when maternal infection was documented in the first and second trimester compared to the third trimester (p=0.018). In 31 cases (35%), the pregnant women were treated from the time of diagnosis until delivery with spiramycin, and no differences were found regarding the rate of vertical transmission or the appearance of clinical manifestations among the newborns of treated and non-treated mothers treated. CONCLUSIONS: The prevalence of congenital toxoplasmosis was higher than that reported in other European countries. The prevalence of intracranial calcifications was higher than that described in the literature, whereas retinochoroiditis and strabismus occurrence was lower. Brain lesions in newborns were more frequent in first- and second-trimester infections. There was no difference in the rate of vertical transmission and in the occurrence of clinical manifestations among newborns whose mothers received spiramycin during gestation and those whose mothers did not receive treatment.

Eccentric fixation patterns, clinical findings, and reading speed in patients with bilateral toxoplasmic macular retinochoroiditis / Padrões de fixação excêntrica, achados clínicos e velocidade de leitura em pacientes com retinocoroidite macular bilateral por toxoplasmose

ABSTRACT Purpose: To study visual acuity, refractive errors, eccentric fixation, and reading performance in patients with toxoplasmic macular retinochoroiditis. Methods: Twenty-three participants with bilateral toxoplasmic macular retinochoroiditis and 4 with toxoplasmic macular retinocho­roiditis in their unique eye were evaluated. Participants reported their eye dominance, confirmed by the Portus and Miles test. Best corrected visual acuity, spherical equivalent refraction, magnification need, and reading speed were measured. Microperimetry (MAIA, Centervue - Padova, Italy) recorded the preferred retinal locus and fixation stability by means of the bivariate contour ellipse area. Fourteen eyes from 14 normally sighted subjects served as controls. Results: Mean ± SD best corrected visual acuity was better in the dominant eye than in the nondominant eye: 0.9 ± 0.2 (logMAR 0.5 to 1.4) vs. 1.2 ± 0.3 (logMAR 0.6 to 1.7) (p<0.0001, paired t-test). Spherical equivalent myopia of -4.00 or higher was present in 42% of the eyes. Microperimetry was performed in 42 eyes. Eccentric fixation was observed in all examined eyes. In 14 eyes (33%), the preferred retinal locus was placed (in the retina) superior temporal to the macular lesion, in 10 (24%) superior nasal, in 6 (14%) inferior temporal, and in 12 (28%) inferior nasal. There was no significant difference in the distribution of the preferred retinal locus position between dominant and nondominant eyes (p=0.85, Pearson test). There was no correlation between reading speed and the distance between the preferred retinal locus and the estimated original foveal position (r=-0.09; p=0.73), the bivariate contour ellipse area (r=-0.19; p=0.44), or best corrected visual acuity (r=0.024; p=0.92). Conclusions: Myopia is more prevalent in patients with toxoplasmic macular retinochoroiditis. Reading speed is not dependent on preferred retinal locus position, stability, or visual acuity. Nevertheless, documentation of fixation provides new data on the impact of visual impairment in these patients and may be useful for rehabilitation efforts.

RESUMO Objetivo: Estudar a acuidade visual, erros de refração, fixação excêntrica e desempenho de leitura em pacientes com retinocoroidite macular por Toxoplasmose. Métodos: Vinte e três pacientes com retinocoroidite macular por Toxoplasmose bilateral e quatro com retinocoroidite macular por Toxoplasmose no seu único olho foram avaliados. Os participantes relataram sua dominância ocular, confirmada pelo teste de Portus e Miles. A acuidade visual melhor corrigida, refração em equivalente esférico, magnificação necessária e velocidade de leitura foram medidas. A microperimetria (MAIA, Centervue - Padova, Italy) registrou a estabilidade preferida do locus e da fixação da retina por meio da área da elipse de con­torno bivariada. Quatorze olhos de 14 pacientes com boa visão serviram como controles. Resultados: A média ± DP da acuidade visual melhor corrigida foi melhor no olho do­minante do que no não dominante: 0,9 ± 0,2 (logMAR 0,5 a 1,4) vs. 1,2 ± 0,3 (logMAR 0,6 a 1,7) (p<0,0001, teste t pareado). Miopia em equivalente esférico de -4,00 ou maior estava presente em 42% dos olhos. Microperimetria foi realizada em 42 olhos. Fixação excêntrica foi observada em todos os olhos examinados. Em 14 olhos (33%), o locus retiniano preferencial estava localizado, na retina, na região súpero-temporal à lesão macular, em 10 (24%) súpero-nasal, em 6 (14%) ínfero-temporal, e em 12 olhos (29%) ínfero-nasal. Não houve diferença significativa na distribuição da posição do locus retiniano preferencial entre olhos dominantes e não dominantes (p=0,85, teste de Pearson). Não houve correlação entre velocidade de leitura e distância entre o locus retiniano preferencial e a posição foveal original estimada (r=-0,09; p=0,73), a área bivariada de contorno elipsóide (r=-0,19; p=0,44) ou acuidade visual melhor corrigida (r=0,024; p=0,92). Conclusões: A miopia é mais prevalente em pacientes com retinocoroidite macular por Toxoplasmose. A velocidade de leitura não é dependente da posição do locus retiniano preferencial, da estabilidade ou da acuidade visual. A documentação do padrão de fixação excêntrica, entretanto, oferece novos dados no impacto da deficiência visual nesses pacientes e pode ser útil em estratégias de reabilitação.

Chorioretinitis sclopetaria caused by an intraorbital metallic foreign body / Coriorretinite esclopetária causada por um corpo estranho metálico intraorbitário

ABSTRACT A 44-year-old man was referred for evaluation of pain and temporal floaters after receiving a rebounded bullet impact to his right eye. Typical funduscopic findings, together with the confirmed presence of an intraorbital metallic foreign body, led to the diagnosis of chorioretinitis sclopetaria. Conservative management was performed as no severe symptoms were observed. The favorable clinical outcome was confirmed in subsequent reviews. Chorioretinitis sclopetaria is characterized by a proliferative chorioretinal inflammation as a consequence of the expansive wave caused by the entrance of a bullet between the eyeball and the orbit.

RESUMO Um homem de 44 anos foi encaminhado para avaliação de dor e flutuadores temporais após receber um impacto de bala ressaltado em seu olho direito. Achados fundoscópicos típicos, juntamente com a presença confirmada de um corpo estranho metálico intraorbitário, levaram ao diagnóstico de coriorretinite esclopetária. O manejo conservador foi realizado, pois não foram observados sintomas graves. O desfecho clínico favorável foi confirmado em revisões subsequentes. A coriorretinite esclopetária é caracterizada por uma inflamação coriorretiniana proliferativa como consequência da onda expansiva causada pela entrada de uma bala entre o globo ocular e a órbita.

Clinical features and treatment of syphilitic scleritis / 眼科新进展

Objective To summarize and describe clinical features and treatment outcome of syphilitic scleritis.Methods A retrospective study was conducted in patients diagnosed as syphilitic scleritis from 2011 to 2016 in our hospital.Clinical characteristics and prognosis were evaluated.Results Seven patients (7 eyes) were diagnosed as syphilitic scleritis by clinical and serological examinations.All patients were unaware that they had syphilis infection before visit.The ocular manifestation was the only clinical fmdings in three patients.Both treponema pallidum particle agglutination and rapid plasma regain were positive.Meanwhile,the scleritis infection was excluded,tests for human immunodeficiency virus (HIV) were negative.Syphilitic scleritis was unilateral in all patients,and the duration was from one week to two years.Initial symptoms were varied in degree of ocular redness,pain and visual impairment.Two patients presented with anterior episcleritis,nodular anterior scleritis was found in three patients,one patient showed diffuse anterior scleritis,and one patient presented with diffuse episcleritis combined with acute syphilitic posterior placoid chorioretinitis.All patients were treated with penicillin G,and inflammation resolved quickly after treatment.Conelusion Syphilitic scleritis is rare and ease to be misdiagnosed,various types of anterior scleritis is the main manifestation.Syphilitic serologic test should be performed for the suspected cases.The prognosis is well with anti-syphilis therapy.

Objective To discuss the optical coherence tomography (OCT)characteristics in patients with syphilitic chorioretinitis.Methods This was a retrospective cohort study.58 patients (88 eyes) with syphilitic chorioretinitis were included.The fluorescence fundus angiography (FFA),indocyanine green angiography (ICGA) and OCT examination were performed,and the rapid plasma regain test (RPR) and treponema pallidum particle agglutination test (TPPA) were also made.The treatment response and follow up results were analyzed.Results In this study,87 eyes represented as needle like projections of the retinal pigment epithelium,86 eyes represented as retinal external membrane and myoid,ellipsoid structure was unclear or disappear,68 eyes represented as high reflection points within the vitreous body,16 eyes represented as shallow retinal detachment.After treatment,the needle like projections of the retinal pigment epithelium were fully restored in 79 eyes,retinal external membrane and myoid,ellipsoid structure were partial displayed in 62 eyes,and shallow retinal detachment were fully restored in 16 eyes.Conclusion The manifestations of OCT in patients with syphilitic chorioretinitis include needle like projections of the retinal pigment epithelium,unclear or disappear retinal external membrane and myoid,ellipsoid structure,high reflection points within the vitreous body and shallow retinal detachment.The above manifestations of OCT can be recovered significantly with treatment.

Prevalência de cicatrizes coriorretinianas em exames angiográficos / Prevalence of chorioretinal scars in angiographics exams

RESUMO A toxoplasmose é uma zoonose que tem como agente etiológico o Toxoplasma gondii, que se caracteriza por ser uma doença infecciosa de distribuição mundial. Considera-se que no mundo existam mais de 2 bilhões de pessoas infectadas pela toxoplasmose. É bem conhecido que a toxoplasmose é uma causa frequente de cicatriz coriorretiniana. Nesse grupo de doenças, o exame angiográfico (ou angiofluoresceinografia de retina) é de fundamental importância para o diagnóstico. Objetivo: Realizar um levantamento da prevalência de cicatrizes coriorretinianas em angiografias em serviço privado na região de Cascavel (PR), Brasil. Métodos: Realização um estudo retrospectivo, transversal, com levantamento de documentos fonte, onde foram analisados 8719 laudos de angiografias de retina realizadas no Instituto da Visão na cidade de Cascavel (PR), Brasil, entre os anos de 2000 a 2011, sendo selecionados como primeiro diagnóstico de cada paciente, completando um total de 4928 exames válidos. As alterações encontradas foram classificadas de acordo com o tipo de cicatriz visualizada, e divididas conforme frequência percentual. Resultados: Observou-se uma prevalência de cicatrizes de 6,38%, sendo que o percentual de cicatriz coriorretiniana encontrado foi de 6,14%. Conclusão: A baixa prevalência de cicatrizes coriorretinianas encontrada na região de Cascavel (PR), Brasil, quando comparada à de Erechim (RS), Brasil, se deve a diversos fatores, tanto climáticos, socioculturais e institucionais. Além das cicatrizes coriorretinianas, que representaram o maior número entre as cicatrizes, foram encontrados outros subtipos cicatriciais com prevalências menores.

ABSTRACT Toxoplasmosis is a zoonosis whose etiologic agent is Toxoplasma gondii, which is characterized as an infectious disease of worldwide distribution. There are thought to be more than 2 billion people globally infected with toxoplasmosis. It is well known that toxoplasmosis is a frequent cause of chorioretinal scarring. In this group of diseases, the angiographic examination (or retinal fluorescein angiography) is very important for diagnosis. Objective: To perform a survey on the prevalence of chorioretinal scars in angiography at a private clinic in the area of Cascavel, Paraná State, Brazil. Methods: This was a retrospective, cross-sectional study with collection of data from source documents, involving the analysis of 8,719 reports of retinal angiograms performed at the Instituto da Visão of Cascavel, Brazil, between the years 2000-2011. The first diagnosis of each patient was selected, completing a total of 4,928 valid exams. The changes were classified according to the type of visualized scarring, and divided as percentage frequency. Results: We observed a prevalence of 6.38% scars, and the percentage of chorioretinal scars was found to be 6.14%. Conclusion: The low prevalence of chorioretinal scars found in the region of Cascavel, Brazil, when compared with the region of Erechim (Rio Grande do Sul State), Brazil, is due to climatic, sociocultural and institutional factors. Besides the chorioretinal scars, which represent the largest group of scars, other subtypes of scars with lower prevalence were found.

Ocular Syphilis Presenting as both Optic Neuritis and Chorioretinitis in both Eyes

PURPOSE: To report a patient with ocular syphilis, who showed variable ocular manifestations, including optic neuritis and chorioretinitis in both eyes over a short time period. CASE SUMMARY: A 44-year-male visited our clinic for central scotoma in the left eye. The visual acuity was 20/25 in the right eye and 20/40 in the left eye. The fundus of the left eye showed a slightly hyperemic optic disc and multiple yellowish deposits. One week later, visual acuity and fundus lesion improved to 20/20 without a definitive treatment. However, 1 month later, he reported a new deterioration of vision in his right eye to 20/40. The right eye had a relative afferent pupillary defect and the fundus examination showed a blurred optic disc margin. Serological work-up was recommended but the patient refused. He returned 3 weeks later with an improvement in the right eye vision (20/25) and a worsening in the left eye (20/200). The examination revealed an improvement of the previously blurred disc margin in the right eye and newly developed chorioretinitis with vasculitis in the left eye. A serological test was performed. The venereal diseases research laboratory titer was 1:32. The fluorescent treponemal antigen absorbance test as positive for IgG and IgM. He was diagnosed with ocular syphilis and referred to the infectious disease department. He was treated with antibiotics. Six months later, the visual acuity was 20/20 in both eyes and the previous fundus lesions had disappeared. CONCLUSIONS: Ocular syphilis should be considered in patients with atypical and variable clinical course.

Ocular toxoplasmosis with positive polymerase chain reaction in peripheral blood ­ report of two cases, São Paulo State, Brazil / Toxoplasmose ocular com reação em cadeia da polimerase positiva em sangue periférico ­ relato de dois casos, estado de São Paulo, Brasil

Aims: To describe the use of polymerase chain reaction (PCR) in peripheral blood and demonstrate its importance in the clinical follow-up of patients with ocular toxoplasmosis. Case description: Two immunocompetent patients were clinically diagnosed with acute ocular toxoplasmosis. The routine clinical evaluation consisted of fundus examination using binocular indirect ophthalmoscopy, color fundus photography, fluorescein angiography, and spectral domain optical coherence tomography. The serological diagnosis was made by enzyme-linked immunosorbent assay (ELISA) and confirmed by enzyme-linked fluorescent assay (ELFA). The molecular diagnosis was made by PCR in peripheral blood using the B1 gene of Toxoplasma gondii as marker. The younger patient was male, had previous lesion in the right eye, complained of low visual acuity in the left eye and was under treatment. The older patient was male, had retinal detachment, and presented with sudden loss of acuity in the right eye. The fundus examination revealed chorioretinal scar in the left eye. IgG was reactive, IgM was non-reactive, and PCR was positive in the peripheral blood of both patients. New blood samples were collected for serological and molecular monitoring and PCR remained positive in both cases. Six weeks after treatment with oral sulfadiazine and pyrimethamine, the PCR yielded negative results. Conclusion: The results show that T. gondii antigens may be found in peripheral blood during ocular reactivations and that PCR may be a good tool for the follow-up of patients with ocular toxoplasmosis.

Objetivos: Descrever o uso da reação em cadeia da polimerase (PCR) no sangue periférico e demonstrar sua importância no acompanhamento clínico de pacientes com toxoplasmose ocular. Descrição dos casos: Dois pacientes imunocompetentes foram clinicamente diagnosticados com toxoplasmose ocular aguda. Rotineiramente, a avaliação clínica foi feita por fundoscopia com o uso de oftalmoscópio binocular indireto, retinografia colorida, angiografia fluorescente e tomografia de coerência óptica espectral. A sorologia foi realizada por ensaio imunoenzimático (ELISA) e confirmada por ensaio imunoenzimático fluorescente ELFA (IgG, IgM). O diagnóstico molecular foi realizado por PCR em sangue periférico usando o gene B1 de Toxoplasma gondii como marcador. O paciente mais jovem era do sexo masculino, apresentava lesão prévia no olho direito, queixa de baixa acuidade visual no olho esquerdo e estava sob tratamento. O paciente mais velho era do sexo masculino, apresentava descolamento de retina e súbita diminuição de visão no olho direito. A fundoscopia revelou cicatriz coriorretiniana no olho esquerdo. Ambos os pacientes tinham IgG reagente, IgM não reagente e PCR positivo em sangue periférico. Novas amostras de sangue foram coletadas para monitoramento sorológico e molecular e a PCR permaneceu positiva em ambos os casos. Seis semanas após o início do tratamento com sulfadiazina e pirimetamina oral, os resultados do PCR tornaram-se negativos. Conclusões: Os resultados mostram que antígenos de T. gondii podem ser encontrados em sangue periférico durante as reativações oculares e que a PCR parece ser uma boa ferramenta para o acompanhamento de pacientes com toxoplasmose ocular.

Visual function and macular architecture in patients with inactive zone 2 and 3 toxoplasmic retinochoroiditis / Função visual e arquitetura macular em pacientes com retinocoroidite toxoplásmica inativa nas zonas 2 e 3

ABSTRACTPurpose:To evaluate the visual function and architecture of the central and peripapillary retina in patients with inactive toxoplasmic retinochoroiditis outside the macular and peripapillary regions (zones 2 and 3).Methods:Cross-sectional study of 20 eyes (18 patients) with zone 2 and 3 toxoplasmic scars and visual acuity ≥20/25. Patients underwent Humphrey 10-2 perimetry, contrast sensitivity (Mars test), and color vision testing (L'Anthony desaturated D-15). The retinal nerve fiber layer (RNFL) and macular thicknesses were determined by optical coherence tomography.Results:The patients' mean age was 27.4 ± 10.3 years, and the mean duration of remission was 6.15 ± 5.19 months. Abnormal contrast sensitivity and color vision were observed in three (15.0%) and four eyes (20.0%), respectively. Mean deviation (MD) and pattern standard deviation (PSD) fell outside the 95% normal confidence limits of the perimeter's database in 14 (70.0%) and seven eyes (35.0%), respectively. Foveal and mean RNFL thicknesses were within the normal limits in all eyes. Eyes with zone 2 retinochoroiditis had lower foveal sensitivity than eyes with zone 3 lesions (p=0.041). Eyes with a longer duration of remission had a higher MD (r=0.575; p=0.013) and a lower PSD (r=-0.593; p=0.010).Conclusions:Despite normal central and peripapillary retinal architecture, eyes with inactive zone 2 and 3 toxoplasmic retinochoroiditis can present with abnormal color, contrast, and macular perimetric sensitivity. Zone 2 retinochoroiditis was associated with lower foveal sensitivity, and a longer duration of retinochoroiditis remission was associated with better perimetric parameters (MD and PSD).

RESUMOObjetivo:Avaliar a função visual e arquitetura da retina central e peripapilar em pacientes com retinocoroidite toxoplásmica inativa fora da região macular e peripapilar (zonas 2 e 3).Métodos:Estudo transversal de 20 olhos (18 pacientes) com cicatrizes toxoplásmicas nas zonas 2 e 3 com acuidade visual ≥20/25. Os pacientes foram submetidos à perimetria Humphrey 10-2, teste de sensibilidade ao contraste (Teste Mars) e teste de visão de cores (L'Anthony D-15 dessaturado). As espessuras da camada de fibras nervosas da retina (CFNR) e da mácula foram determinadas pela tomografia de coerência óptica.Resultados:A média de idade dos pacientes foi 27,4 ± 10,3 anos, e a duração média da remissão da retinocoroidite foi de 6,15 ± 5,19 meses. Alterações na sensibilidade ao contraste e cores foram observada em, respectivamente, 3 olhos (15,0%) e 4 olhos (20,0%). Os índices perimétricos mean deviation (MD) e pattern standard deviation (PSD) estiveram fora do intervalo de confiança de 95% do perímetro em 14 olhos (70,0%) e 7 olhos (35,0%), respectivamente. A espessura foveal e da CFNR média estiveram dentro do limite da normalidade em todos os olhos. Olhos com retinocoroidite na zona 2 tiveram menor sensibilidade foveal que olhos com lesões na zona 3 (p=0,041). Olhos com remissão de longa duração tiveram um MD mais alto (r=0,575; p=0,013) e um PSD mais baixo (r=-0,593; p=0,010).Conclusão:Apesar da arquitetura normal da retina central e peripapilar, olhos com retinocoroidite inativa nas zonas 2 e 3 podem apresentar anormalidades da visão de cores, sensibilidade ao contras e perimetria macular. A retinocoroidite na zona 2 está associada a uma menor sensibilidade foveal. Longos intervalos de remissão da retinocoroidite estiveram associados a melhores parâmetros perimétricos (MD e PSD).

Local treatment of toxoplasmic retinochoroiditis with intravitreal clindamycin and dexamethasone / Tratamento local para a retinocoroidite toxoplásmica com clindamicina e dexametasona intravítrea

ABSTRACTPurpose:To report the clinical outcomes of local treatment of toxoplasmic retinochoroiditis (TRC) with intravitreal injections of clindamycin and dexamethasone.Methods:Study population: 16 eyes (16 patients) with active TRC sparing the macula and juxtapapillary area treated with intravitreal injections of clindamycin (1 mg) and dexamethasone (1 mg) without concomitant systemic antitoxoplasmic or anti-inflammatory therapy. Measured parameters: Best-corrected visual acuity (BCVA) was measured by an Early Treatment Diabetic Retinopathy Study (ETDRS) chart. BCVA and clinical characteristics of retinochoroiditis were assessed at baseline and at 1, 3, 6, and 12 months. Primary outcome measures: Resolution of retinochoroiditis and changes in BCVA.Results:Control of TRC was achieved in all cases with a mean interval of 2.48 ± 1.03 weeks (2-6 weeks). A single injection of intravitreal clindamycin and dexamethasone was performed in 12 patients, and four patients required two intravitreal injections, during the follow-up period. Fourteen eyes (87.5%) improved ≥ 2 ETDRS lines of BCVA, of two or more Early Treatment Diabetic Retinopathy Study lines, BCVA remained stable in two eyes (12.5%), and no patient had decreased BCVA at the end of the follow-up period. No ocular or systemic adverse events were observed.Conclusion:Local treatment with intravitreal injections of clindamycin and dexamethasone without concomitant systemic therapy was associated with resolution of TRC in patients without macular or juxtapapillary involvement. Intravitreal clindamycin and dexamethasone may represent a viable treatment option in patients with allergies or inadequate responses to oral medications.

RESUMOObjetivo:Reportar os resultados clínicos do tratamento local da retinocoroidite toxoplásmica com injeções intravítreas de clindamicina e dexametasona.Métodos:População do estudo: 16 olhos (16 pacientes) com retinocoroidite toxoplásmica ativa sem comprometimento da mácula e da área juxtapapilar, tratados com injeções intravítreas de clindamicina (1 mg) e dexametasona (1 mg) sem terapia sistêmica anti-toxoplásmica ou anti-inflamatória concomitante. Procedimento de observação: A melhor acuidade visual corrigida (BCVA) foi medida através da tabela ETDRS. A BCVA e as características clínicas da retinocoroidite foram avaliadas na qualificação, primeiro, terceiro, sexto e 12º mês. Medidas do resultado principal: resolução da retinocoroidite e mudanças na BCVA.Resultados:O controle da retinocoroidite toxoplásmica foi atingido em todos os casos com um intervalo médio de 2,48 ± 1,03 semanas (intervalo de 2 a 6 semanas). Uma única injeção intravítrea de clindamicina e dexametasona foi aplicada em 12 pacientes, e quatro pacientes precisaram de duas injeções durante o seguimento. Quatorze olhos (87,5%) melhoraram ≥ 2 linhas ETDRS de BCVA, a BCVA ficou estável em 2 olhos (12,5%) e nenhum paciente apresentou diminuição da acuidade visual no final do seguimento. Não foram observados eventos adversos sistêmicos ou oculares.Conclusão:O tratamento local com injeções intravítreas de clindamicina e dexametasona sem terapia sistêmica concomitante esteve associado com a resolução da retinocoroidite toxoplásmica em pacientes sem comprometimento macular ou juxtapapilar. A clindamicina e dexametasona intravítrea representam um tratamento promissor em pacientes com intolerância, contraindicação ou resposta inadequada a medicação oral.

Aborto espontâneo e toxoplasmose ocular em um casal infectado com Toxoplasma gondii / Spontaneous abortion and ocular toxoplasmosis in a couple infected with Toxoplasma gondii

OBJETIVOS: Relatar os casos de um casal, em que a esposa apresentou toxoplasmose na gestação e o esposo, após 15 anos, foi diagnosticado com toxoplasmose ocular. RELATO DOS CASOS: Gestante, grávida de gêmeos, residente de um estado na região Sul do Brasil. No primeiro mês de gestação apresentou sorologia não reagente para IgG e IgM anti-Toxoplasma gondii. Na sétima semana de gestação houve soroconversão (IgM e IgG anti-T.gondii reagentes) e aborto natural. O esposo, após 15 anos desde o episódio da esposa, queixou-se de visão embaçada/irritada. O exame de fundoscopia revelou lesões típicas de coriorretinite recidivante por toxoplasmose no olho direito. Os exames sorológicos foram IgG anti-T.gondii reagente e IgM anti-T.gondii não reagente. CONCLUSÕES: Este relato, de um casal com desfechos clínicos importantes de toxoplasmose, em diferentes formas, enfatiza a relevância do problema da toxoplasmose, que nas suas diversas manifestações, pode trazer graves consequências para a vida de uma família.

AIMS: To report the cases of wife and husband with toxoplasmosis. The woman acquired the infection during pregnancy while her husband was diagnosed with ocular toxoplasmosis 15 years later. CASES REPORT: A woman with twin pregnancy, living in southern Brazil, was seronegative for Toxoplasma gondii IgG and IgM antibodies in the first month of gestation. Seroconversion (positive T. gondii IgM and IgG antibodies) occurred in the seventh week of gestation, resulting in spontaneous abortion. Fifteen years later, her husband presented with eye irritation and blurred vision. The funduscopic examination revealed typical lesions of recurrent chorioretinitis in the right eye. The serological tests were positive for T. gondii IgG and negative for IgM. CONCLUSIONS: This report of a couple with important clinical outcomes of two different types of toxoplasmosis underscores the importance of this disease which, in its various manifestations, may have serious consequences for a family's life.
