First steps towards the deinstitutionalization of older adults: A protocol for the implementation of a complex intervention / Primeros pasos en la desinstitucionalización de adultos mayores: protocolo para la implementación de una intervención compleja

Background: Nursing homes are becoming increasingly important as end-of-life care facilities. However, many older adults want to stay in their homes as they age. Objective: To assess the feasibility of a deinstitutionalization process on selected institutionalized older adults who are willing to initiate the process. Methods: This study, divided into two phases, will be carried out over 15 months on 241 residents living in two nursing homes in Navarra (Spain). The first phase has a cross-sectional design. We will identify the factors and covariates associated with feasibility and willingness to participate in a deinstitutionalization process by bivariate analysis, essential resources for the process and residents to participate in the process. The second phase has a complex interventional design to implement a deinstitutionalization process. An exploratory descriptive and comparative analysis will be carried out to characterize the participants, prescribed services and the impact deinstitutionalization intervention will have over time (quality of life will be the main outcome; secondary variables will be health, psychosocial, and resource use variables). This study will be accompanied by a pseudo-qualitative and emergent sub-study to identify barriers and facilitators concerning the implementation of this process and understand how intervention components and context influence the outcomes of the main study. Intervention components and the way the intervention is implemented will be of great relevance in the analysis. Discussion: Alternatives to institutionalization with adapted accommodation and community support can allow people who wish to return to the community.(AU)

Introducción: Las residencias de personas mayores cobran cada vez más importancia como centros de atención al final de la vida. Sin embargo, muchos adultos mayores desean permanecer en sus casas mientras envejecen. Objetivo: Se pretende evaluar la viabilidad de un proceso de desinstitucionalización en adultos mayores seleccionados que viven en las residencias y que expresen la voluntad para iniciar el proceso. Métodos: Este estudio, dividido en dos fases, se llevará a cabo durante 15 meses en 241 sujetos que viven en dos residencias de personas mayores en Navarra (España). La primera fase tiene un diseño transversal en donde se identificarán los factores y covariables asociadas a la viabilidad y voluntad para participar en un proceso de desinstitucionalización a través de un análisis bivariante, los recursos imprescindibles para el proceso y los residentes que quieran participar en él. La segunda fase tiene un diseño de intervención compleja en la que se implementa un proceso de desinstitucionalización. Se realizará un análisis exploratorio descriptivo y comparativo para caracterizar a los participantes, los servicios prescritos y el efecto de la intervención de desinstitucionalización a lo largo del tiempo (la calidad de vida será la variable principal; las secundarias serán las referentes a la salud, las psicosociales y de uso de recursos). Este estudio irá acompañado de un subestudio pseudocualitativo y emergente para identificar las barreras y los elementos facilitadores relativos a la implementación de este proceso y comprender cómo los componentes de la intervención y el contexto influyen en los resultados del estudio principal. Los componentes de la intervención y su ejecución serán de gran relevancia en el análisis. Discusión: Las alternativas a la institucionalización con viviendas adaptadas y apoyos comunitarios pueden permitir a las personas que así lo desean el retorno a la comunidad.(AU)

Approach to the care process by nurse case managers in a breast unit.

OBJECTIVE: Breast units led by nurse case managers are being implemented to provide comprehensive care in the detection and treatment of breast cancer. However, their implementation is heterogeneous and the results of the care process with this professional have not been studied. The aim of the study is to describe the management in time and the approach of the process by a nurse case manager in the breast unit of women with suspected breast cancer pathology, derived from the breast cancer screening program. METHODS: Descriptive, cross-sectional, retrospective study carried out in 2021. Women treated in a breast unit managed by a nurse case manager in a hospital in southern Spain were included. Sociodemographic, clinical and care process characteristics were analysed RESULTS: A total of 118 women of Spanish nationality (92%) participated, with a mean age of 59 years. The diagnosis of malignancy was made in 74.6% of them. Seventy-nine percent of the women had their first visit within 3 days. The mean time to diagnosis was 3.98 days (SD: ±3.93), 4.2 weeks (SD: ±1.84) to initiate treatment and a total in-hospital time of 33 days (SD: ±13.45). CONCLUSIONS: The management of nurse case managers in breast units contributes to improving or speeding up times, in accordance with international guidelines, helping this approach in the continuity of the care process for women referred after screening for breast cancer detection.

Protective effect of dietary micronutrients on gastric cancer risk among Jordanians / Efecto protector de los micronutrientes de la dieta ante el riesgo de cáncer gástrico entre jordanos

Objective: several dietary and non-dietary factors and genetic predisposition may play an important role in gastric carcinogenesis. The findingsabout associations between micronutrients and gastric cancer (GC) is still inconsistent. This study aimed to investigate the effect of dietarymicronutrients on gastric cancer risk.Methods: a case-control study comprised of 173 GC (107 males: 66 females) patients and 313 (190 males: 123 females) population-basedcontrols matched for age, occupation, and marital status. Demographics, medical history, physical activity, and nutrient intake information werecollected using reliable interview-based questionnaires. Information on dietary micronutrient intake was collected from the participants using avalidated food frequency questionnaire (FFQ). Multinomial logistic regression was used to calculate Odds ratios (ORs) and their corresponding95 % confidence intervals (CIs) and evaluate associations between dietary micronutrients and GC risk.Results: GC was inversely associated with the consumption of vitamin A, beta-carotene, vitamins D, E, K, B2, B3, B6, B12, and C, folate, chromium,iodine, and selenium. Additionally, a protective effect was observed for consumption of calcium, copper, iron, magnesium, phosphate, sodium,and zinc. In almost all the micronutrients, the second tertile showed a more pronounced reduction in GC risk as compared to the first tertile.Conclusions: our data support favorable effects of dietary consumption of some vitamins and minerals against GC ris.(AU)

Adicionalmente, se observó un efecto protector para el consumo de calcio, cobre, hierro, magnesio, fosfato, sodio y zinc. En casitodos los micronutrientes, el tercer tercil mostró una reducción más pronunciada del riesgo de CG en comparación con el primer tercil en hombres.Por el contrario, el segundo tercil exhibió un nivel de protección significativamente marcado en comparación con el primer tercil en mujeres.Conclusiones: nuestros datos respaldan los efectos favorables del consumo dietético de algunas vitaminas y minerales para el riesgo dedesarrollar cáncer gástrico.(AU)

Immune thrombocytopenia in systemic lupus erythematosus: Prevalence, risk factors, and a novel predictive model for risk assessment.

INTRODUCTION: Immune thrombocytopenia (ITP) is a potentially severe manifestation of systemic lupus erythematosus (SLE) reported in 7-40% of SLE patients. ITP has been associated with a higher risk of organ damage and mortality. OBJECTIVES: To describe which factors are associated with the presence of ITP in SLE patients. METHODS: Retrospective case-control study. Cases were defined as SLE patients who had ever developed ITP and were sex- and age-matched with two controls. A predictive model was constructed to identify SLE patients who were at risk of developing ITP. RESULTS: ITP prevalence in our SLE cohort was 8.35%. Cases had a higher frequency of hemolytic anemia, while controls had a higher prevalence of arthritis at SLE diagnosis. During SLE progression, cases tested positive for anticardiolipin, anti-ß2-glycoprotein 1, and lupus anticoagulant antibodies more frequently. Cases received mycophenolic acid and azathioprine more often than controls and had a higher SLICC/ACR score. The model demonstrated a sensitivity of 87.53%, a positive predictive value of 81.92%, a specificity of 80.50%, area under the curve of 83.92%, a F1 of 83% and an overall accuracy of 83.68%. The variables that best explain the model were hemolytic anemia, arthritis, oral ulcers, Raynaud's phenomenon, low C4, low CH50, anticardiolipin and anti-ß2GP1 antibodies. CONCLUSION: SLE patients who develop ITP have a distinct phenotype characterized by more hemolytic anemia and less arthritis at SLE onset, and higher prevalence of antiphospholipid syndrome antibodies during SLE progression. This phenotype is associated with heightened organ damage and the need for more intensive therapies and stricter follow-up. Our predictive model has demonstrated an impressive ability to identify SLE patients at risk of developing ITP.

Impact of prior use of antiplatelets on COVID-19 susceptibility, progression, and severity: a population-based study.

INTRODUCTION AND OBJECTIVES: Hypercoagulability and thromboembolism are processes that arise from severe acute respiratory syndrome coronavirus 2 infection and are responsible for a high degree of coronavirus disease 2019 (COVID-19)-related morbidity and mortality. This study sought to assess the effect of antiplatelet drugs on COVID-19 severity (risk of hospitalization and mortality), susceptibility to severe acute respiratory syndrome coronavirus 2 infection, and progression to severe COVID-19. METHODS: We conducted a population-based case-control study in a northwestern region of Spain in 2020. The study involved 3060 participants with a positive polymerase chain reaction test who were hospitalized, 26 757 participants with a positive polymerase chain reaction test who were not hospitalized, and 56 785 healthy controls. RESULTS: Triflusal seemed to be associated with a significant increase in risk of hospitalization (aOR, 1.97; 95%CI, 1.27-3.04) and susceptibility to infection (OR, 1.45; 95%CI, 1.07-1.96). It also appeared to lead to a nonsignificant increase in the risk of mortality (OR, 2.23; 95%CI, 0.89-5.55) and/or progression to more severe disease stages (OR, 1.42; 95%CI, 0.8-2.51). Aspirin seemed to be associated with a statistically significant decrease in susceptibility to severe acute respiratory syndrome coronavirus 2 infection (OR, 0.92; 95%CI, 0.86-0.98). CONCLUSIONS: Triflusal use appears to increase the risk of susceptibility to COVID-19 infection and an even higher risk of hospitalization, whereas the other antiplatelets could be associated with a reduction in the risk of the various outcomes or have no effect on risk. These findings could support reconsideration of triflusal prescription in COVID-19 pandemic situations.

Contrasting Cases in Two Psychotherapeutic Processes Based on Integrative Behavior Couple Therapy / Contraste de casos en dos procesos psicoterapéuticos basados en la terapia de pareja conductual integradora

The present study proposes an evaluation of the therapeutic process in relation to the follow-ing aspects: the therapist adherence, the items which are more and less characteristic in the treatment and the interaction structures, along the therapeutic process of two cases of couple therapy,one with significant positive clinical change and one with significant negative clinical change, in the couple's evaluation. This work used Integrative Behavioral Couple Therapy mod-el, one of the approaches of the third wave therapies.The method was a study of contrasting cases. The similarities and differences between the cases were discussed, reaching the conclu-sion that there are aspects of the couple, the therapist, the therapeutic relationship and the context that may have contributed to the different outcomes. (AU)

El presente estudio propone una evaluación del proceso terapéutico en relación con los siguientes aspectos: la adherencia del terapeuta, los ítems más y menos característicos en el tratamiento y las estructuras de interacción, a lo largo del proceso terapéutico de dos casos de terapia de pareja, uno con cambio clínico positivo significativo y otro con cambio clínico negativo significativo, en la evaluación de la pareja. En este trabajo se utilizó el modelo de Terapia de Pareja Conductual Integrativa, uno de los enfoques de las terapias de tercera ola. El método fue un estudio de casos contrastados. Se discutieron las similitudes y diferencias entre los casos, llegando a la conclusión de que hay aspectos de la pareja, del terapeuta, de la relación terapéutica y del contexto que pueden haber contribuido a los diferentes resultados.

Persistencia del cavum septum pellucidum y cavum vergae asociado a retraso psicomotor. Informe de caso

Fundamento: Dos de las tres formas en que se presentan los quistes intracraneales de la línea media anterior son: cavum septum pellucidum y cavum vergae; estos normalmente desaparecen después del nacimiento, de persistir suelen ser asintomáticos, pero también pueden estar asociados a manifestaciones obstructivas, trastornos psicóticos o alteraciones del neurodesarrollo que demandan de un seguimiento clínico. Objetivo: Reportar el caso de un paciente de 6 meses con persistencia de estructuras del periodo embrionario en posible asociación con retraso del desarrollo psicomotor. Presentación de caso: Por lo infrecuente que resulta en la práctica, se informa el caso de un paciente de 6 meses con una persistencia del cavum septum pellucidum y cavum vergae en el que se destaca la posible asociación del retraso del neurodesarrollo a la persistencia de estas estructuras. El diagnóstico se realizó de forma precoz y se intervino oportunamente. Conclusiones: La presentación del caso aportó evidencias epidemiológicas que favorecen la posible asociación entre la persistencia de estas estructuras embrionarias y el retraso del desarrollo psicomotor.

Background: Two out of the three forms in which intracranial anterior midline cysts present are: These usually disappear after birth; if they persist, they are often asymptomatic, but may also be associated with obstructive manifestations, psychotic disorders or neurodevelopmental disorders that require clinical follow up. Objective: To report a case of a 6-month-old patient with persistence of embryonic period structures in possible association with psychomotor developmental retardation. Case presentation: Because of how infrequent it is in practice, a case of a 6-month-old patient with a persistent cavum septum pellucidum and cavum vergae is reported in which the possible association of neurodevelopmental delay with the persistence of these structures is pointed out. The diagnosis was made in an early manner and it was timely intervened. Conclusions: The case presentation provided epidemiological evidences that encourage the possible association among the persistence of these embryonic structures and psychomotor developmental retardation.

Corneal ectasia following photorefractive keratectomy: a confocal microscopic case report and literature review / Ectasia corneana após ceratectomia fotorrefrativa: relato de caso de microscopia confocal e revisão da literatura

ABSTRACT The occurrence of corneal ectasia after photorefractive keratectomy is a rare but serious complication of refractive surgery. Possible risk factors are not well assessed, but a probable reason is the failure to detect keratoconus preoperatively. In this report, we describe a case of corneal ectasia after photorefractive keratectomy in a patient who presented a suspicious tomography pattern preoperatively but had no degenerative alterations associated with pathologic keratoconus, as revealed by in vivo corneal confocal microscopy. We also review eligible case reports of post-photorefractive keratectomy ectasia to find similar characteristics.

RESUMO A ocorrência de ectasia corneana após ceratectomia fotorrefrativa é uma complicação rara, porém grave, em cirurgia refrativa. Os possíveis fatores de risco não são bem avaliados, mas a opinião atual é que a falha na detecção de ceratocone pré-operatório possa ser o principal motivo. Neste relato, descrevemos um caso de ectasia corneana após ceratectomia fotorrefrativa em paciente apresentando padrão tomográfico suspeito no pré-operatório, mas sem alterações degenerativas associadas a ceratocone patológico, conforme revelado por microscopia confocal in vivo da córnea. Além disso, revisamos, na literatura, relatos de casos elegíveis de ectasia pós-ceratectomia fotorrefrativa para encontrar características semelhantes.

Apical bleeding: a rare cause of blindness after orbital decompression / Sangramento apical: uma causa rara de cegueira pós descompressão orbitária

ABSTRACT Orbital decompression is widely performed for the management of proptosis for cosmetic and functional cases of Graves orbitopathy. The main side effects include dry eye, diplopia, and numbness. Blindness after orbital decompression is extremely rare. The mechanisms of vision loss after decompression are not well described in the literature. Considering the devastating effect and rarity of this complication, this study presented two cases of blindness after orbital decompression. In both cases, vision loss was provoked by slight bleeding in the orbital apex.

RESUMO A descompressão orbitária é uma cirurgia amplamente empregada para correção da proptose em casos cosméticos e funcionais da orbitopatia de Graves. Os principais efeitos colaterais induzidos pela descompressão são olho seco, diplopia e parestesias. Amaurose pós descompressão é uma complicação extremamente rara e cujos mecanismos são pouco discutidos na literatura. Considerando o efeito devastador representado pela perda visual e a escassez de relatos dessa complicação, os autores apresentam dois relatos de amaurose após descompressão orbitária. Nos dois casos a perda visual ocorreu devido a sangramento de pequena monta no ápice orbitário.

Partial regression of peripapillary myelinated nerve fibers after non-arteritic anterior ischemic optic neuropathy / Regressão parcial das fibras nervosas peripapilares mielinizadas após neuropatia óptica isquêmica anterior não arterítica

ABSTRACT A 71-year-old woman presented a non-arteritic anterior ischemic optic neuropathy in an optic nerve with previously registered superonasal peripapillary myelinated nerve fibers. Her past medical history was significant for controlled systemic hypertension, hyperlipidemia, and diabetes mellitus. The physiologic cup was absent in both optic discs. Non-arteritic anterior ischemic optic neuropathy mainly affected the temporal and inferior sectors of the peripapillary retinal nerve fiber layer, as could be demonstrated by retinal nerve fiber layer optical coherence tomography and optic disc optical coherence tomography angiography. Unlike other published reports, just a slight regression of the myelinated nerve fibers was observed after 1 year of follow-up. This occurred because ischemia mainly affected the temporal and inferior peripapillary sectors, whereas myelinated nerve fibers were superonasal to the optic disc.

RESUMO Uma mulher de 71 anos de idade apresentou neuropatia óptica isquêmica anterior não arterítica no nervo óptico com fibras nervosas peripapilares mielinizadas previamente registradas. Seu histórico médico foi significativo para hipertensão arterial sistêmica controlada, hiperlipidemia e diabetes mellitus. Em ambos os discos ópticos, a tacícula fisiológica esteve ausente. A neuropatia óptica isquêmica anterior não arterítica afetou principalmente os setores temporal e inferior da camada de fibras nervosas da retina peripapilar, como demonstrado pela tomografia de coerência óptica da camada de fibras nervosas da retina e pela angiotomografia de coerência óptica do disco óptico. Ao contrário de outros relatórios publicados, apenas uma ligeira regressão das fibras nervosas mielinizadas foi observada após um ano de acompanhamento. Isto pode ser explicado pelo fato da isquemia ter afetado principalmente os setores temporal e inferior peripapilares, enquanto as fibras nervosas de mielina eram nasal superior ao disco óptico.

Simultaneous unilateral central retinal vein occlusion and branch retinal artery occlusion after Coronavirus Disease 2019 (COVID-19) mRNA vaccine / Oclusão unilateral simultânea da veia retiniana central e artéria retiniana ramificada após vacina mRNA COVID-19

ABSTRACT A 51-year-old non-obese woman presented with a one-week history of progressive blurry vision within the inferior visual field of her left eye. Her only relevant past medical history was long-standing hypothyroidism and recent vaccination against Coronavirus Disease 2019 (COVID-19) with an mRNA vaccine 12 days before the onset of symptoms. At examination, the anterior segment was unremarkable, but the retinal fundus revealed a central retinal vein occlusion associated with a branch retinal artery occlusion of the superior temporal branch in her left eye. Ancillary tests to rule out thrombophilia, hyperviscosity, hypercoagulability, or inflammation were negative. Ultrasound tests were also negative for a cardiac or carotid origin of the branch retinal artery occlusion. At two-month follow-up, no new retinal vascular occlusive events were observed. Although the best-corrected visual acuity at presentation was 8/10 in the left eye, the final best-corrected visual acuity remained 3/10.

RESUMO Uma mulher de 51 anos, não obesa, apresentou história de uma semana de visão embaçada progressiva no campo visual inferior do olho esquerdo. Seu único histórico médico anterior relevante era hipotireoidismo de longa data e uma recente vacinação contra a Doença de Coronavírus 2019 (COVID-19), com vacina de mRNA, 12 dias antes do início dos sintomas. O exame mostrou segmento anterior normal, mas o fundo da retina revelou uma oclusão da veia central da retina associada a uma oclusão de ramo arterial da retina do ramo temporal superior no olho esquerdo. Testes auxiliares para descartar trombofilia, hiperviscosidade, hipercoagulabilidade ou inflamação apresentaram resultados negativos. Testes de ultrassom também foram negativos quanto a uma origem cardíaca ou da carótida da oclusão do ramo da artéria da retina. Após dois meses de acompanhamento, nenhum novo evento vascular oclusivo retiniano foi observado. Embora, a acuidade visual melhor corrigida na apresentação tenha sido de 8/10 no olho esquerdo, a acuidade visual final melhor corrigida permaneceu em 3/10.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

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.

Mycobacterium abscessus keratitis after LASIK surgery / Ceratite por Mycobacterium abscessus após cirurgia LASIK

ABSTRACT A 33-year-old male presented with unilateral subacute infectious keratitis 4 weeks after surgery. Corneal inflammation was resistant to standard topical antibiotic regimens. During diagnostic flap lifting and sampling, the corneal flap melted and separated. Through flap lifting, corneal scraping, microbiological diagnosis of atypical mycobacteria, and treatment with topical fortified amikacin, clarithromycin, and systemic clarithromycin, clinical improvement was achieved.

RESUMO Paciente do sexo masculino, 33 anos, apresentou ceratite infecciosa subaguda unilateral 4 semanas após a cirurgia. A inflamação da córnea foi resistente aos regimes de antibióticos tópicos padrão. A aba da córnea foi derretida e seccionada durante o levantamento e amostragem para diagnóstico. A melhora clínica só foi alcançada após levantamento do retalho, raspagem e diagnóstico microbiológico de micobactérias atípicas e tratamento com amicacina fortificada tópica, claritromicina e claritromicina sistêmica.

Descemet's membrane endothelial keratoplasty for primary graft failure after penetrating keratoplasty / Transplante endotelial de membrana de Descemet para falência primária após transplante penetrante

ABSTRACT Primary graft failure (PGF) is a known complication following penetrating keratoplasty (PKP). The usual approach to treat this complication is to repeat a penetrating keratoplasty. Here, we report a case of Descemet's membrane endothelial keratoplasty (DMEK) for the treatment of PGF after PKP. A patient that underwent PKP, developed PGF with persistent graft edema and very poor visual acuity despite aggressive steroid use and a proof anti-viral treatment. Three months after the initial surgery, a DMEK was performed under the PKP graft. There was progressive early corneal clearing and, by the end of the first month, the patient already had no corneal edema. Uncorrected visual acuity (UCVA) improved to 20/40 and best corrected visual acuity (BCVA) to 20/20. DMEK may be an alternative to a second PKP for the treatment of PGF. This technique is a less invasive option when compared to the standard PKP procedure.

RESUMO A falência primária do enxerto é uma complicação conhecida que pode ocorrer após o transplante penetrante de córnea. O tratamento usual dessa complicação é com um novo transplante penetrante. Apresentamos um caso em que foi usado o transplante endotelial de membrana de Descemet (DMEK - do inglês Descemet membrane endo-thelial keratoplasty) para o tratamento da falência primária após o transplante penetrante. Uma paciente submetida a transplante penetrante evoluiu com falência primária do enxerto a despeito do uso intenso de corticoide tópico e uma prova terapêutica de antivirais. Três meses após a cirurgia inicial, foi optado pela realização do transplante endotelial de membrana de Descemet sob o transplante penetrante. Houve um clareamento precoce e progressivo do enxerto com melhora importante da visão. Após um mês, a visão sem correção era de 20/40 melhorando para 20/20 com refração. O transplante endotelial de membrana de Descemet pode ser uma alternativa a um novo transplante penetrante como tratamento da falência primária.

Morphofunctional evaluation of peripapillary retinoschisis associated with myopic posterior staphyloma and hyaloid traction: does it cause peripapillary vitreoretinal traction? / Avaliação morfofuncional da retinosquise peripapilar associada ao estafloma posterior miópico e à tração hialoidea: isso causa tração vitreo-retiniana peripapilar?

ABSTRACT This case report presents the details of a 33-year-old female patient who was referred to a specialized retina service because of mild vision loss in her right eye). The patient's visual acuity was 20/25 in right eye and 20/50 in the left eye (; amblyopic); the spherical equivalent was -12.75 diopters (right eye) and -14.75 diopters (left eye). Multimodal retinal imaging showed peripapillary schisis in both the inner and outer retinal layers, grade II posterior vitreous detachment, and a tessellated fundus. Using Humphrey perimetry and MP-3 microperimetry, the functional evaluation indicated macular sensitivity within normal limits and decreased sensitivity in the peripapillary region, especially in right eye. The pattern-re versal visual evoked potential was measured. The N75 and P100 latency and amplitude in right eye were within normal values for checks of 1º. However, the amplitude was low for checks of 15′. Highly myopic patients who have posterior staphyloma that involves the optic nerve are susceptible to posterior hyaloid traction, and the resulting peripapillary vitreous traction may compromise vision.

RESUMO Este relato de caso apresenta um paciente feminino de 33 anos encaminhado para um serviço especializado de retina devido à leve perda de visão em olho direito. A acuidade visual foi de 20/25 no olho direito e 20/50 no olho esquerdo, o equivalente esférico foi de -12,75 dioptrias e -14,75 dioptrias, respectivamente. Avaliações multimodais revelaram isquese peripapilar nas camadas internas e externas da retina, descolamento vítreo posterior grau II e fundo tesselado. Avaliação funcional com perimetria Humphrey e microperimetria MP-3 revelaram sensibilidade macular normais e diminuição da sensibilidade na região peripapilar, especialmente no olho direito. Potencial visual evocado de padrão reverso apresentou no olho direito latência e amplitude N75 e P100 dentro dos valores normais para verificação de 1º. Entretanto, a amplitude foi baixa para a de 15′. Pacientes alto míopes com esfiloma posterior envolvendo o nervo óptico são suscetíveis à tração da hialoide posterior. Portanto a tração vitreopapilar resultante pode causar comprometimento da visão.

Glioma of the optic nerve and chiasm: a case report / Glioma óptico-quiasmático: um relato de caso

ABSTRACT This article reports the case of an 11-year-old male patient with a history of proptosis and low progressive visual acuity in the left eye. He presented with a best corrected visual acuity of 20/25 in the right eye and light perception in the left eye. Exotropia and limitation in adduction were observed in the left eye. On automated perimetry, inferiortemporal quadrantopsia was observed in the right eye, while total scotoma was observed in the left eye. On magnetic resonance imaging, there was an expansive lesion in the left optic nerve, extending to the brainstem with chiasmatic involvement. This article aims to report a case of optic pathway glioma, as well as to discuss its clinical findings and their interconnection with the current literature.

RESUMO Este artigo relata o caso de um paciente do sexo masculino, 11 anos de idade, com história de proptose e baixa de acuidade visual progressiva. Ao exame oftalmológico apresentava melhor acuidade visual de 20/25 em olho direito e percepção de luz em olho esquerdo. Existia exotropia e limitação à adução no olho esquerdo. À campimetria automatizada, observou-se quadrantopsia temporal inferior em olho direito e escotoma total em olho esquerdo. À ressonância magnética, evidenciou-se lesão expansiva em trajeto do nervo óptico esquerdo estendendo-se até região do tronco encefálico, com acometimento quiasmático. O objetivo deste artigo é relatar o glioma de vias ópticas, bem como discutir os achados e sua interligação com a literatura atual.

Erdheim-Chester disease with chorioretinal and orbital involvement: a case report / Doença de Erdheim-Chester com envolvimento coriorretiniano e orbitário: relato de caso

ABSTRACT A 42-year-old woman presented with bilateral proptosis, chemosis, leg pain, and vision loss. Orbital, chorioretinal, and multi-organ involvement of Erdheim-Chester disease, a rare non-Langerhans histiocytosis, with a negative BRAF mutation was diagnosed based on clinical, radiological, and pathological findings. Interferon-alpha-2a (IFNα-2a) was started, and her clinical condition improved. However, 4 months later, she had vision loss with a history of IFNα-2a cessation. The same therapy was administered, and her clinical condition improved. The Erdheim-Chester disease is a rare chronic histiocytic proliferative disease that requires a multidisciplinary approach and can be fatal if left untreated because of multisystemic involvements.

RESUMO Uma mulher de 42 anos apresentou proptose bi-lateral, quemose, dor nas pernas e perda de visão. Com base em achados clínicos, radiológicos e patológicos, foi diag-nosticada doença de Erdheim-Chester com acometimento orbitário, coriorretiniano e multiorgânico. Trata-se de uma rara histiocitose não Langerhans negativa para a mutação BRAF. Foi iniciado tratamento com interferon alfa-2a (IFNα-2a) e o quadro clínico melhorou. No entanto, quatro meses depois, a paciente apresentou perda visual após a cessação do IFNα-2a. A mesma terapia foi administrada novamente e sua condição clínica melhorou novamente. A doença de Erdheim-Chester é uma doença proliferativa histiocítica crônica rara que necessita de uma abordagem multidisciplinar e pode ser fatal se não tratada, devido a envolvimentos multissistêmicos.
