ABSTRACT

ABSTRACT Purpose: We aimed to study reported cases of nasopharyngeal carcinoma presenting with ophthalmic manifestations with and without a prior diagnosis of nasopharyngeal carcinoma. Methods: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A literature search was conducted using the MEDLINE database in PubMed and Google Scholar. We included patients with a previous diagnosis of nasopharyngeal carcinoma in Group I and those without a prior diagnosis of nasopharyngeal carcinoma in Group II. Data included demographics, clinical presentation, history of nasopharyngeal carcinoma, treatment, histopathological description, World Health Organization classification, and outcome. Results: Fifty-eight patients (26 in Group I and 32 in Group II) were included. The male-to-female ratio was 3:1. The mean age of the patients (53.3 ± 11.7 years and 54.8 ± 16.2 years, respectively) and gender did not differ significantly between the two groups. The most common ocular presentations were diplopia and proptosis in the first group (each in 34.6%), whereas visual disturbance was most common in the second group (46.9%). Treatment options and World Health Organization grading were comparable. The outcome in 38 patients (after a comparable follow-up period) was significantly better in group II (p=0.003). There was no statistically significant difference in the outcome of 23 patients in correlation with World Health Organization grades II versus III irrespective of group (p=0.094). Conclusions: The demographics of patients with nasopharyngeal carcinoma presenting with ophthalmic manifestations were similar between the two study groups, with a wide age range and male predominance. Patients presenting initially to ophthalmologists with no history of nasopharyngeal carcinoma have a more favorable outcome. World Health Organization grading may have less value as a prognostic indicator.

ABSTRACT

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.

ABSTRACT

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.


RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

ABSTRACT

ABSTRACT Schirmer strips and conjunctival swabs are used in ophthalmology for the collection of tears and fluids. One of the biggest challenges during the COVID-19 pandemic has been accurate diagnosis and, in some cases, ocular manifestations are among the first symptoms. In this context, this study aimed to collect evidence to support the use of Schirmer strips and conjunctival swabs as a method of sample collection for viral analysis. A literature search was conducted following the Scoping Review protocol defined by The Joanna Briggs Institute. Studies were analyzed regarding virus research, collection methods, and sample analysis. The findings support that viruses can be detected on the ocular surface through analysis of Schirmer strips and conjunctival swabs. However, additional studies with larger samples and time data are necessary to confirm these conclusions.


RESUMO A fita de Schirmer e o swab conjunctival são utilizados na oftalmologia como métodos de coleta para lágrimas e fluidos. Durante a pandemia da COVID-19, um dos desafios foi o diagnóstico correto e se sabe que, em alguns casos, as manifestações oculares podem ser um dos primeiros sintomas. Nesse contexto, este estudo tem como objetivo levantar evidência que destaque o uso de fitas de Schirmer e de swabs conjuntivais como método de coleta para análise viral. Conduziu-se uma revisão de literatura seguindo o protocolo para Scoping Review definido pelo Joanna Briggs Institute. Os pesquisadores analisaram os estudos em busca do vírus pesquisado, os métodos de coleta e os métodos de análise. Vírus podem ser detectados na superfície ocular através da análise de fitas de Schirmer e de swabs conjuntivais, entretanto novos estudos com populações maiores e com definições claras de tempo são necessários para conclusões mais assertivas no tema.

ABSTRACT

ABSTRACT Purpose: The current study aimed to evaluate the effects of the coronavirus disease 2019 (COVID-19) on choroidal thickness using enhanced depth imaging optical coherence tomography. Methods: This study evaluated the right eyes from 41 post-COVID-19 cases (Group 1) and 41 healthy subjects (Group 2). Choroidal thickness was measured using enhanced depth imaging optical coherence tomography. Post-COVID-19 cases were evaluated within 1 month after a diagnosis of COVID-19. Two experienced ophthalmologists measured the choroidal thickness at the subfovea, temporal, and nasal quadrants at 500-μm intervals up to 1500 μm from the fovea at seven different points. Moreover, central macular thickness and ganglion cell layer thickness were measured via OCT, after which both two groups were compared. Results: Group 1 showed a significantly thicker choroid compared to Group 2 at the subfovea, 500 μm temporal to the fovea, 500 and 1000 μm nasal to the fovea (p=0.011, p=0.043, p=0.009, and p=0.019, respectively). Although other areas measured were also thicker in Group 1, the difference was not significant (p>0.05). Moreover, no significant difference in the central macular thickness and ganglion cell layer thickness were observed between the groups (p>0.05). Conclusion: Choroidal thickness was increased in post-COVID-19 patients, which might be related to inflammation associated with the pathogenesis of COVID-19.


RESUMO Objetivo: Avaliar o efeito da doença por coronavírus de 2019 (COVID19) na espessura da coroide usando tomografia de coerência óptica com profundidade de imagem aprimorada. Métodos: Este estudo consistiu em 41 casos pós-COVID19 (Grupo 1) e 41 indivíduos saudáveis (Grupo 2). Apenas os olhos direitos dos participantes foram incluídos no estudo. A espessura da coroide foi medida usando tomografia de coerência óptica com profundidade de imagem aprimorada. Nos casos pós-COVID19, as medições foram realizadas dentro de 1 mês da doença. A espessura da coroide foi medida por dois oftalmologistas experientes nos quadrantes subfoveal, temporal e nasal, em sete pontos diferentes, a intervalos de 500 a 1500 μm da fóvea. Além disso, a espessura macular central e a espessura da camada de células ganglionares foram medidas com OCT e os dois Grupos foram comparados. Resultados: As espessuras coroidais foram estatisticamente mais espessas no Grupo 1 que no Grupo 2, com 500 μm no quadrante subfoveal, 500 Symbol (OTF)m no temporal e 1000 μm no nasal (p=0,011, p=0,043, p=0,009 e p=0,019, respectivamente). Embora outras medidas tenham se mostrado mais espessas no Grupo 1, elas não foram estatisticamente significativas (p>0,05). Também não houve diferenças significativas entre os Grupos quanto à espessura macular central e à espessura da camada de células ganglionares (p>0,05). Conclusão: A espessura da coroide mostrou-se aumentada em pacientes pós-COVID19. Isso pode estar relacionado à inflamação que faz parte da patogênese do COVID19.

ABSTRACT

ABSTRACT Amyloidosis is a rare disease in which ocular involvement may occur as an isolated event or associated with a systemic disease. This paper describes two clinical cases of ophthalmologic manifestations of amyloidosis: a bilateral eyelid lesion similar to xanthelasma and tarsal conjunctival disease similar to follicular conjunctivitis. The anatomopathological analysis confirmed the diagnosis.


RESUMO A amiloidose é uma doença rara que pode ter o acometimento ocular como forma isolada ou estar associada a doenças sistêmicas. Neste relato, são descritos dois casos clínicos de alterações oftalmológicas da amiloidose: um que se manifestou por meio de lesão palpebral bilateral de aspecto similar ao xantelasma. O outro era uma afecção em conjuntiva tarsal, semelhante à conjuntivite folicular. O estudo anatomopatológico confirmou o diagnóstico.

ABSTRACT

RESUMO A doença de Tay-Sachs é um distúrbio neurodegenerativo autossômico recessivo, o qual envolve o metabolismo dos lipídios, levando ao acúmulo de gangliosídeos nos tecidos, devido à deficiência da enzima hexosaminidase A. Esse depósito progressivo resulta em perda da função neurológica e, quando acomete as células ganglionares da mácula, causa o achado típico da doença, a "mácula em cereja". A patologia é diagnosticada por meio dos níveis de hexosaminidase A e hexosaminidase total no soro, além análise do DNA do gene HEXA. Este caso relata uma criança com doença de Tay-Sachs cujo diagnóstico foi suspeitado por conta dos achados oftalmológicos.


ABSTRACT Tay-Sachs Disease is an autosomal recessive neurodegenerative disorder, which involves the metabolism of lipids, leading to the accumulation of gangliosides in the tissues, due to the deficiency of the enzyme Hexosaminidase A. This progressive deposit results in loss of neurological function and, when it affects macula ganglion cells, it causes the typical disease finding, the "cherry red spot". The pathology is diagnosed through the levels of Hex A and total Hexosaminidase in the serum, in addition to the analysis of the DNA of the HEXA gene. This case reports a child with Tay-Sachs disease with a suspected diagnosis was through ophthalmologic findings.

ABSTRACT

ABSTRACT Monkeypox disease is a viral zoonosis with symptoms similar to those seen in the past in smallpox (variola), although clinically less severe. Following the eradication of smallpox in 1980 and the subsequent cessation of smallpox vaccination, monkeypox has emerged as the most important orthopoxvirus from a public health standpoint. Monkeypox virus occurs primarily in central and western Africa, often in tropical forests, and has increasingly manifested in urban areas. Animal hosts include various rodents and nonhuman primates. We report the case of a patient with monkeypox disease who developed ocular complaints (eye discomfort and conjunctivitis) and had detectable conjunctival lesions on biomicroscopy and fluorescein testing. Its ophthalmological manifestations are still poorly known.


RESUMO Varíola do Macaco é uma zoonose viral com sintomas semelhantes aos observados no passado em pacientes com Varíola, embora seja clinicamente menos grave. Com a erradicação da varíola em 1980 e a subsequente cessação da vacinação contra a varíola, a varíola dos macacos emergiu como o ortopoxvírus mais importante em saúde pública. O vírus monkeypox ocorre principalmente na África central e ocidental, muitas vezes nas proximidades de florestas tropicais, e tem se manifestado cada vez mais em áreas urbanas. Os hospedeiros animais incluem uma variedade de roedores e primatas não humanos. O presente estudo relata o caso de um paciente com Monkeypox que evoluiu com queixa oftalmológica de desconforto ocular e conjuntivite e, à biomicroscopia e teste da fluoresceína, detecção de lesões conjuntivais. Alterações oftalmológicas da doença são, ainda, pouco conhecidas.

ABSTRACT

ABSTRACT Purpose: This study evaluated the frequency of the most common ophthalmological, neurological, and systemic findings in symptomatic patients seen at a COVID-19 screening service at Hospital das Clínicas - Universidade Federal de Pernambuco. Methods: A total of 104 patients under clinical suspicion of SARS-CoV-2 infection underwent medical evaluation through an ophthalmological and systemic symptoms survey. All participants selected for the study underwent COVID-19 RT-PCR testing. Results: The mean age was 38.8 years, with 44.23% between 31 and 40 years old, 68.27% female, and 31.73% male. The most common symptoms in patients with a positive RT-PCR test were cough (69.23%), fever (42.3%), hyposmia (38.46%), myalgia (38.46%), and ageusia (30.77%). In the positive group, 34.61% presented with ophthalmological symptoms: burning (19.23%), eye pain (11.54%), foreign body sensation (7.7%), hyperemia (7.7%), and tearing (3.84%). Conclusions: Systemic clinical features were characteristic of upper respiratory infection, but neurological findings of hyposmia and anosmia proved to be important markers for suspicion of SARS-CoV-2 infection. Ophthalmic symptoms in patients with COVID-19 were similar to those observed in other viral conditions and may precede systemic conditions. A high rate of self-medication was observed for general symptoms compared with ophthalmological conditions.


RESUMO Objetivo: Avaliar a frequência dos sintomas oftalmológicos, neurológicos e sistêmicos mais comuns em pacientes sintomáticos atendidos no serviço de triagem de COVID-19 do Hospital das Clínicas da UFPE. Métodos: Cento e quatro pacientes com suspeita clínica de infecção por Sars-Cov-2 foram submetidos a avaliação médica e aplicação de questionário sobre a sintomatologia oftalmológica, neurológica e sistêmica. Todos os participantes do estudo tiveram exame de RT-PCR para COVID-19 solicitado. Resultados: A média de idade foi de 38,8 anos, com 44,23% entre 31 e 40 anos. Mulheres corresponderam a 68,27% dos atendimentos e homens a 31,73%. Os sintomas mais frequentes nos pacientes com RT-PCR positivo foram: tosse (69,23%), febre (42,3%), mialgia (38,46%), hiposmia (38,46%), e ageusia (30,77%). Neste grupo, os sintomas oftalmológicos estiveram presentes em 34,61%, sendo: ardor (19,23%), dor ocular (11,54%), sensação de corpo estranho (7,7%), hiperemia (7,7%) e lacrimejamento (3,84%) os mais encontrados. Conclusões: O quadro clínico sistêmico foi característico de infecção respiratória alta, porém os achados neurológicos de hiposmia e anosmia mostraram-se importantes marcadores para a suspeição dos casos de infecção por COVID-19. Os sintomas oftalmológicos dos pacientes com COVID-19 foram semelhantes aos presentes em outros quadros virais, podendo preceder o quadro sistêmico. Houve uma alta taxa de automedicação para os sintomas gerais quando comparado ao quadro oftalmológico.

ABSTRACT

ABSTRACT This study attempts to review whether the coronavirus disease-2019 (COVID-19) is transmitted through the ocular surface and examine the symptoms and signs of ocular disease. Considering that COVID-19 is transmitted by airborne droplets and close contact with infected individuals, we will also review the conditions to which eye clinics and ophthalmologists should pay attention to prevent the transmission of the disease. Although some researchers have argued that COVID-19 transmission cannot occur through the ocular surface, most of them are of the opinion that the ocular surface is a potential pathway of transmission. Until date, ocular signs and symptoms have been rarely reported in the COVID-19 patients. However, there are case reports of conjunctivitis as the first, and rarely, the only clinical symptom of the disease. In addition, low coronavirus RNA positivity can be detected in the ocular surface samples. Further laboratory and clinical investigations are needed to ascertain whether the ocular surface is one of the potential transmission pathways through which severe acute respiratory syndrome-coronavirus 2 can gain entry into the human body.


RESUMO Rever se o COVID- 19 é transmitido através da su perfície ocular e seus sintomas e sinais na doença ocular. Dado que o COVID-19 é transmitido por gotículas de ar e contato próximo, também analisaremos, também, as condições às quais os oftalmologistas e as clínicas oftalmológicas devem prestar atenção a fim de evitar a transmissão da doença. Embora alguns autores tenham argumentado que a transmissão de COVID-19 não pode ocorrer através da superfície ocular, a maioria dos autores acredita que a superfície ocular é uma via potencial de transmissão. Até à data, foram notificados, muito raramente, sinais e sintomas oculares em doentes com COVID- 19. No entanto, há relatos de casos de conjuntivite como sendo, raramente, o primeiro e único sintoma clínico da doença. Além disso, a baixa positividade do RNA coronavírus pode ser detectada nas amostras da superfície ocular. São necessárias mais investigações clínicas laboratoriais sobre se a superfície ocular é uma das vias de transmissão através das quais o SARS-COV-2 penetra no corpo humano.

ABSTRACT

RESUMO Objetivo: Avaliar sintomas astenópicos e fatores sociodemográficos, hábitos comportamentais e clínicos nos docentes universitários durante a pandemia da COVID-19. Métodos: Trata-se de estudo transversal que avaliou a ocorrência de astenopia em 104 docentes. Questionários de sintomatologia visual validados foram adaptados para a coleta de dados. Houve comparação dos docentes quanto à ocorrência ou não de sintomas astenópicos, bem como foi aplicada regressão logística binária, para aferir a associação com variáveis independentes (p<0,05). Resultados: Houve maior aparecimento de sintomas astenópicos durante o período pandêmico, em que o tempo de exposição a telas parece ter sido o fator mais determinante. Além disso, os indivíduos com tempo de tela superior a 5 horas diárias, que faziam uso de telas para o lazer e usavam colírio/lubrificantes apresentaram significativamente maior chance de estar no grupo com sintomas astenópicos. Conclusão: Foi identificada associação significativa entre a ocorrência de sintomas astenópicos e o uso de telas durante o período pandêmico, principalmente nos grupos com maior duração do tempo de tela. O estudo chama atenção para a saúde ocular de docentes universitários em ensino remoto, além de suscitar novos estudos para investigação desse quadro em distintos ambientes escolares.


ABSTRACT Objective: To assess asthenopic symptoms and sociodemographic factors, behavioral and clinical aspects in college lecturers during the COVID-19 pandemic. Methods: This is a cross-sectional study evaluating asthenopia in 104 lecturers. Some validated visual symptom questionnaires were adapted for data collection. Lecturers were compared regarding the occurrence or not of asthenopic symptoms, and binary logistic regression was applied to measure the association with independent variables (p<0.05). Results: Asthenopic symptoms occurred more often during the pandemic, when exposure to screens was a determinant factor. The individuals with screen time longer than five hours a day, who used screens for leisure, and who used eye drops/lubricants were significantly more likely to be in the group with asthenopic symptoms. Conclusion: A significant association was identified in occurrence of asthenopic symptoms and screen use during the pandemic period, especially in groups with longer screen time. The study draws attention to the eye health of college lecturers in distance learning, and the need for further research on this situation in different school environments.

ABSTRACT

ABSTRACT Purpose: To identify ocular manifestations in patients with Chikungunya fever in the chronic phase and describe their sociodemographic profile. Methods: Patients with serologic confirmation of Chikungunya infection were included in this transverse study. All subjects underwent a comprehensive ophthalmologic evaluation, including specific lacrimal function tests (tear break-up time test, Schirmer test, and lissamine green). Results: Overall, 64 eyes of 32 patients were evaluated. Most patients were women (71.9%), with the mean age of 50.0 ±13.7 years. The mean interval between serologic confirmation and the examination was 12.7 ±7.7 months. Twenty patients (62%) presented with dry eye. No statistically significant association was observed between dry eye and infection diagnosis time (p=0.5546), age (p=0.9120), sex (p=1.00), race (p=0.2269), arthralgia in acute infection (p=0.7930), retro-orbital pain (p=0.3066), and conjunctivitis (p=1.00). Conclusion: Dry eye was the most prevalent manifestation observed. No signs of intraocular inflammation and affected visual acuity were observed.


RESUMO Objetivo: Identificar manifestações oculares em pacientes na fase crônica da febre Chikungunya e descrever seu perfil sociodemográfico. Métodos: Estudo transversal com a inclusão de pacientes com confirmação sorológica de febre Chikungunya. Todos os pacientes foram submetidos a exame oftalmológico completo, incluindo testes específicos de função lacrimal (teste de ruptura do filme lacrimal, teste de Schirmer e teste da lissamina verde). Resultados: Foram avaliados 64 olhos de 32 pacientes. A maioria dos pacientes eram do sexo feminino (71,9%) e a idade média foi 50,0 ±13,7 anos. O intervalo médio entre a confirmação sorológica e o exame oftalmológico foi de 12,7 ±7,7 meses. Vinte pacientes (62%) apresentaram olho seco. Não houve significância estatística na associação entre olho seco e o tempo de diagnóstico da infecção (p=0,5546), idade (p=0,9120), sexo (p=1,00), raça (p=0,2269), artralgia durante a infecção aguda (p=0,7930), dor retro-orbitária (p=0,3066) e conjuntivite (p=1,00). Conclusão: A presença de olho seco foi a manifestação mais prevalente observada. Não foram observa dos sinais de inflamação intraocular ou baixa acuidade visual.

ABSTRACT

Introducción: desde los primeros casos de virus de inmunodeficiencia humana (VIH), se conocen manifestaciones oculares secundarias a la infección y estas se han relacionado con el conteo de linfocitos CD4+. Objetivo: describir la correlación entre las manifestaciones oculares en pacientes con VIH y el conteo de linfocitos CD4+. Material y métodos: estudio transversal analítico de pacientes con VIH, en quienes se analizó la correlación entre conteo de CD4+ y manifestaciones oftalmológicas. Resultados: se incluyeron 21 pacientes entre 26 y 67 años de edad. Solo tres no se encontraban en terapia antirretroviral. El 67% presentó algún tipo de manifestación ocular, 42% presentó manifestaciones no relacionadas con la infección, 47% manifestaciones relacionadas y 24% ambas. La microangiopatía de la conjuntiva fue la manifestación ocular más frecuente (35.7%). Hubo una correlación estadísticamente significativa (r = 0.76, p = 0.0001) entre las manifestaciones oculares relacionadas con la infección y el conteo de linfocitos CD4+. Conclusiones: los pacientes con VIH presentan con frecuencia manifestaciones oculares, la mayoría asociadas a la infección. Existe correlación entre la presencia de estas con el conteo de CD4+; sin embargo, un número similar de manifestaciones no asociadas a la infección se presentaron sin correlación con el conteo, por lo que los pacientes con VIH deberían tener revisiones oftalmológicas periódicas, independientemente del conteo de CD4+.


Background: Since the first cases of human immunodeficiency virus (HIV), ocular manifestations secondary to infection have been known and these have been related to the CD4+ lymphocyte count. Objective: To describe the correlation between ocular manifestations in patients with HIV and the CD4+ lymphocyte count. Material and methods: Analytical cross-sectional study of patients with HIV whose CD4+ count was correlated with the presence of ophthalmological manifestations. Results: 21 patients between 26 and 67 years were studied. Only 3 patients were not on antiretroviral therapy. 67% of the patients presented some type of ocular manifestation, 42% presented non-infection related manifestations, 47% related manifestations and 24% both. Conjunctival microangiopathy was the most frequent ocular manifestation (35.7%). There was a statistically significant correlation (r = 0.76, p = 0.0001) between eye manifestations related to infection and CD4+ lymphocyte count. Conclusions: Patients with HIV frequently present ocular manifestations, the majority related to infection; there is a correlation between the presence of these with the CD4+ count. However, a similar number of manifestations not related to infection occurred without correlation with the count; therefore, HIV patients should have periodic ophthalmological examinations, independently of CD4+ count.

ABSTRACT

RESUMO No final do século vinte, com o surgimento de novas tecnologias e de novos programas espaciais, a medicina aeroespacial ganhou destaque no meio científico uma vez que os estudos relacionados às alterações da fisiologia humana no espaço tornaram-se cada vez mais necessário para a manutenção da saúde de cosmonautas. Os olhos são considerados uma das estruturas mais sensíveis do corpo às alterações vasculares, estruturais e bioquímicas provocadas pela microgravidade e radiação cósmica. Nesse sentido, essa revisão narrativa busca identificar e explicar as principais alterações morfológicas e funcionais que ocorrem no sistema visual em decorrência de missões espaciais.


ABSTRACT At the end of the twentieth century, with the emergence of new technologies and new space programs, aerospace medicine gained prominence in the scientific community since studies related to changes in human physiology in space have become increasingly necessary for the maintenance of cosmonaut health. The eyes are considered one of the most sensitive structures in the body to vascular, structural and biochemical changes caused by microgravity and cosmic radiation. In this sense, this narrative review seeks to identify and explain the main morphological and functional changes that occur in the visual system as a result of space missions.

ABSTRACT

Introduction:Sickle Cell Disease (SCD) is an inherited haemolytic disorder that affects virtually all body systems including the eye. Ocular complications of SCD could have dire consequences if not detected early. Objectives:We aimed at determining the prevalence of ocular complications of SCD in our patients.Methods: This study was carried out on patients attending both the adult and Paediatric Sickle cell disease clinic at Chukwuemeka OdumegwuOjukwu Teaching Hospital, Akwa, Anambra State Nigeria, over an 8 month period. A structured questionnaire was administered to consenting patients to determine their sociodemographic variables and other characteristics. Visual acuity was determined with multiple optotype Snellen’s chart at 6 metres in natural daylight. Using pen-torch, the face, external eye examination, anterior segment examination and pupillary reaction to light were assessed. Magnified anterior segment examination was performed with slit-lamp biomicroscope. All subjects underwent dilated fundoscopy (after instillation of tropicamide 0.5% eye drop) using Welch Allyn indirect ophthalmoscope.Results were analysed usingSPSS version 22.0 Inc Chicago Illinois and represented in tables. Statistically significant P value was set at < 0.05.Results: A total of 28 patients with age range of 6-42 years were seen. 17(60.7%) were males, while 11(39.3%) were females. 8(28.6%) had at least one ocular anomaly comprising of refractory errors 3(10.8%), sickle cell retinopathy 4(14.3%) and glaucoma 2(7.1%). Only 2 (7.1%) routinely visit eye clinic. SCD retinopathy was found to increase with age (P value= 0.005).Conclusion: SCD retinopathy was found more in the older age group despite the small sample size at a prevalence rate of 14.3%. Early initiation of routine ocular examination for SCD patients will be beneficial to avert these complications. More efforts should be made at educating the patients. Larger studies will be required to determine the actual prevalence of ocular anomaly in SCD patients in Anambra State

ABSTRACT

SUMMARY INTRODUCTION: The Zika virus (ZIKV) is an arbovirus isolated for the first time in 1947 and transmitted to humans by the Aedes aegypti mosquito. In Brasil, it was first detected in May 2015. Since then, ZIKV has been identified as the etiological agent of acute exanthematous disease in Brasil, and Neuropediatricians of the Recife warned about an epidemic of microcephaly, and the Brazilian Ministry of Health confirmed the association between ZIKV and Congenital malformations and neurological syndromes. The eye, as an extension of the developing brain, has been examined in patients with microcephaly and maternal history of ZIKV infection. METHODS: Twenty newborn patients with microcephaly, whose mothers had presumed Zika virus during pregnancy, were analyzed through medical records. The nonparametric chi-square statistic was used to verify the association between head circumference and ocular alteration at a significance level of 0.0001. RESULTS: The significance of P = 0.000 in the value of non-parametric chi-square statistics was lower than the value of α = 0.0001, demonstrating that, at a level of 0.0001, there is an association between head circumference and ocular alteration. CONCLUSION: Although the knowledge of the natural evolution of the disease is still scarce, the current evidence is strong enough to establish a causal relationship between ZIKV infection during pregnancy and the increased incidence of the microcephaly and serious eye alterations that lead to the severe lower vision of these children.


RESUMO: INTRODUÇÃO: O vírus Zika (ZIKV) é um arbovírus isolado pela primeira vez no ano de 1947, sendo transmitido para o homem pelo mosquito Aedes aegypti. No Brasil foi detectado pela primeira vez em maio de 2015. Desde então, ZIKV foi identificado como o agente etiológico da doença exantemática aguda no Brasil, e neuropediatras do Recife deram o sinal de alerta sobre uma epidemia de microcefalia, tendo o Ministério da Saúde do Brasil confirmado a associação entre ZIKV e malformações congênitas e síndromes neurológicas. O olho, sendo uma extensão do cérebro em desenvolvimento, tem sido examinado em pacientes com microcefalia e história materna de infecção por ZIKV. MÉTODO: Foram analisados, por meio de prontuário médico, 20 pacientes recém-nascidos, portadores de microcefalia, cujas mães tiveram presumidamente Zika vírus durante a gestação. A estatística não paramétrica Qui-Quadrado foi utilizada para verificar a associação entre perímetro cefálico e alteração ocular, no nível de significância de 0,0001. RESULTADOS: A significância de P=0,000 no valor da estatística não paramétrica de Qui-Quadrado foi menor do que o valor de α = 0,0001, demonstrando que podemos afirmar que, em um nível de 0,0001, há uma associação entre o perímetro cefálico e a alteração ocular. CONCLUSÃO: Apesar de ainda serem escassos os conhecimentos sobre a evolução natural da doença, as evidências atuais são fortes o suficiente para estabelecermos a relação causal entre a infecção pelo ZIKV durante a gravidez e o aumento da frequência da microcefalia e alterações oculares graves que levam à baixa severa da visão dessas crianças.

ABSTRACT

La incontinencia pigmenti es un trastorno neurocutàneo raro, con una frecuencia de 1 en 40 000 recién nacidos, de etiología genética asociada a mutaciones en el gen IKBKG, localizado en Xq28, con herencia dominante ligada al X. Tiene una presentación clínica de manifestaciones muy variables detectadas desde la etapa neonatal y puede asociar afectación cutànea, dental, ocular y neurológica, y cada una de estas con un diagnóstico diferencial distinto. Se presenta a una paciente pediàtrica con diagnóstico de incontinencia pigmenti a la semana de vida. En la evaluación oftalmológica inicial, se observaron lesiones vasculares retinianas. Se decidió el tratamiento con làser, con buenos resultados, y se consiguió estabilizar la visión.


Incontinentia pigmenti is a rare neurocutaneous disorder with a frequency of 1 in 40,000 newborn; it is associated with mutations in IKBKG gene in Xq28, inherited as an X-linked dominant trait. Clinical manifestations detected since the newborn period are highly variable, with skin, teeth, eyes, and nervous system manifestations, and each with a characteristic differential diagnosis. We present a pediatric patient diagnosed with incontinentia pigmenti at the first week of life. In the initial ophthalmologic evaluation, retinal vascular lesions were observed. The outcomes of laser treatment of the ischemic peripheral retina were good and resulted in stability of vision.

ABSTRACT

Resumo Objetivo: Conhecer a prevalência de manifestações oculares em trabalhadores portuários e identificar fatores associados. Métodos: Estudo transversal em um Porto marítimo do extremo Sul do Brasil. Participaram 232 trabalhadores. Para coleta dos dados utilizou-se entrevista estruturada. Foi utilizado teste t de Student para amostras independentes, a fim de comparar as médias dos trabalhadores com manifestações oculares, por meio dos qualificadores em grau no mínimo moderado (presença de manifestações oculares) e aqueles sem manifestações oculares ou grau leve (ausência de manifestações oculares). O teste de Mann-Whitney foi utilizado no caso de assimetria. O teste do qui-quadrado de Pearson ou o teste exato de Fisher foram usados para comparar proporções e a análise de Regressão de Poisson foi usada para controlar os fatores de confusão. Resultados: A prevalência de manifestações oculares autorreferidos foi 92,2%. As manifestações oculares foram: coceira/prurido (49,1%), irritação (41,4%), ardor (39,2%), lacrimejamento (34,9%), sensação de cansaço (32,3%), alteração na pigmentação ocular (26,7%), dor (17,7%), ressecamento dos olhos (14,2%) e sensação de pressão atrás dos olhos (9,9). A utilização de filme para envelopar mercadoria contribuiu para maior prevalência de manifestações oculares. Já a utilização de luvas como equipamento de proteção individual auxiliou na menor prevalências dessas manifestações. Conclusão: Acredita-se que os achados do presente estudo possam subsidiar a avaliação clínica do enfermeiro na abordagem de trabalhadores portuários, assim como direcionar o planejamento e a implementação de cuidados socioambientais condizentes com as necessidades de saúde desses e de outros trabalhadores.

Abstract Objective: To understand the prevalence of ocular manifestations in port workers and identify associated factors. Methods: Cross-sectional study carried out in a seaport in southern Brazil. A total of 232 workers participated in the study. Structured interviews were applied for data collection. Student's t-test was used for independent samples to compare the means of workers with ocular manifestations, applying qualifiers with a moderate minimum level (presence of ocular manifestations) and with a low level or without ocular manifestations (lack of ocular manifestations). The Mann-Whitney test was used for cases of asymmetry. Pearson's Chi-square and Fisher's exact test were carried out to compare the rates, whereas Poisson Regression was used to control the confounding factors. Results: The prevalence of self-reported ocular manifestations was 92.2%. Ocular manifestations were: itching/pruritus (49.1%), rash (41.4%), burning (39.2%), lacrimation (34.9%), fatigue (32.3%), change in ocular pigmentation (26.7%), pain (17.7%), eye dryness (14.2%), and pressure sensation behind the eyes (9.9%). The use of film for wrapping goods contributed to a higher prevalence of ocular manifestations. The use of gloves as personal protective equipment led to a lower prevalence of these manifestations. Conclusion: The findings of the current study may contribute to the clinical assessment of nurses in approaching port workers, as well as to guide the planning and implementation of social and environmental care in line with the health needs of these or other workers.

ABSTRACT

Resumo A doença relacionada ao IgG4 é uma condição imunomediada caracterizada pela presença de lesões com reação inflamatória associada à fibrose e à infiltração linfoplasmocitária rica em plasmócitos tissulares IgG4 positivos, compondo um espectro de doenças fibroproliferativas. A patogênese da DRIgG4 ainda é pouco compreendida e o tratamento é empírico. Relatamos o caso de um homem de 50 anos com lesões amareladas palpebrais associadas a edema local, diagnosticadas previamente como processo alérgico, até que biópsia com estudo imuno-histoquímico e dosagem de IgG4 sérico aventaram a hipótese de doença relacionada ao IgG4. Foi iniciado tratamento com corticoide e rituximabe, observando-se estabilização do quadro e sem apresentação de outras formas clínicas da doença.


Abstract IgG4-Related Disease is an immunomediated condition that is characterized by the presence of inflammatory lesions associated with fibrosis and lymphoplasmacytic infiltration rich in positive IgG4 tissue plasmocytes, forming a spectrum of fibroproliferative diseases. The pathogenesis of IgG4-RD is still poorly understood and the treatment is empirical. We report the case of a 50-year-old man with yellow eyelid lesions associated with local edema, previously diagnosed as an allergic process, until biopsy with immunohistochemical study and serum IgG4 dosage revealed the hypothesis of IgG4 related disease. Treatment with corticoid and rituximab was initiated, showing stabilization of the condition, without presenting other clinical forms of the disease.
