Methicillin-resistant Staphylococcus epidermidis infectious keratitis: Clinical and microbiological profile / Queratitis infecciosa por Staphylococcus epidermidis resistente a meticilina: perfil clínico y microbiológico

Introduction. Staphylococcus epidermidis (SE) is a common cause of bacterial keratitis in certain geographic areas. Ahigh percentage of resistance to methicillin is shown, whichgives it cross resistance to beta-lactams and sometimes resistance to other antibacterial groups. We analyzed clinical andmicrobiological variables in patients with infectious keratitisdue to SE.Methods. Medical records of 43 patients with suspected infectious keratitis and microbiological confirmation for SE,between October 2017 and October 2020, were retrospectively studied. Clinical characteristics (risk factors, size of lesions,treatment, evolution) and microbiological (susceptibility toantibiotics) were analyzed, and groups of patients with methicillin-resistant (MRSE) and methicillin-susceptible (MSSE)infection were compared.Results. MRSE was present in 37.2% of infectious keratitis. All isolates were sensitive to vancomycin and linezolid.Rates of resistance to tetracyclines and ciprofloxacin were50% and 56% in the MRSE group, and 11% and 7% in theMSSE group. The clinical characteristics, including size of lesion, visual axis involvement, inflammation of anterior chamber, presence of risk factors and follow-up time, did not showstatistically significant differences between groups.Conclusions. MRSE is a common cause of infectious keratitis caused by SE and shows a high rate of multidrug resistance. Clinically, it does not differ from MSSE keratitis. Additional work is needed to confirm these findings (AU)

Introducción. Staphylococcus epidermidis (SE) es unacausa frecuente de queratitis bacteriana en ciertas áreas geográficas. Presenta un alto porcentaje de resistencia a meticilina, lo que confiere resistencia cruzada a beta-lactámicos y enalgunas ocasiones también resistencia a otros grupos de antibacterianos. Analizamos variables clínicas y microbiológicas enpacientes con queratitis infecciosa por SE.Métodos. Se analizaron retrospectivamente las historiasclínicas de 43 pacientes con sospecha de queratitis infecciosa yconfirmación microbiológica para SE, entre octubre de 2017 yoctubre de 2020. Se analizaron las características clínicas (factores de riesgo, tamaño de las lesiones, tratamiento, evolución)y microbiológicas (susceptibilidad a antibióticos) y se compararon grupos de pacientes con infección resistente (MRSE) ysensible a meticilina (MSSE).Resultados. El 37,2% de las queratitis fueron por MRSE.Todos los aislados fueron sensibles a vancomicina y linezolid.Las tasas de resistencia a tetraciclinas y ciprofloxacino fueron50% y 56% en el grupo de MRSE, y 11% y 7% en el grupode MSSE. Las características clínicas, incluido el tamaño de lalesión, la afectación del eje visual, la inflamación de la cámaraanterior, la presencia de factores de riesgo y el tiempo de seguimiento, no mostraron diferencias estadísticamente significativas entre los grupos.Conclusiones. MRSE es una causa frecuente de las queratitis infecciosas producidas por SE y presenta una alta tasade resistencia a múltiples fármacos. Clínicamente, no muestradiferencias clínicas con la queratitis por MSSE. Se necesitantrabajos adicionales para confirmar estos hallazgos. (AU)

Primary multifocal anaplastic large cell lymphoma with eyelid involvement: a case report / Linfoma anaplásico de grandes células primário multifocal com envolvimento de pálpebra: relato de caso

ABSTRACT Ocular adnexal involvement in CD30+ lymphoproliferative disorders is rare. We report the case of a 73-year-old woman with a relapsing primary cutaneous anaplastic large cell lymphoma on her eyelid. A systemic extension study excluded extracutaneous involvement. Systemic chemotherapy resulted in an optimal response, with complete regression of the cutaneous lesions. There has been no recurrence during the 2 years of follow-up.

RESUMO O acometimento ocular adicional nos distúrbios linfoproliferativos CD30+ é raro. Relatamos o caso de uma mulher de 73 anos com linfoma de grandes células anaplásicas primárias recidivantes em sua pálpebra. A avaliação sistêmica excluiu envolvimento extracutâneo. A quimioterapia sistémica resultou em uma resposta ótima, com regressão completa das lesões cutáneas. Não houve recidiva durante 2 anos de acompanhamento.

Primary multifocal anaplastic large cell lymphoma with eyelid involvement: a case report.

Ocular adnexal involvement in CD30+ lymphoproliferative disorders is rare. We report the case of a 73-year-old woman with a relapsing primary cutaneous anaplastic large cell lymphoma on her eyelid. A systemic extension study excluded extracutaneous involvement. Systemic chemotherapy resulted in an optimal response, with complete regression of the cutaneous lesions.

ACUTE VISION LOSS AS THE ONLY SIGN OF LEUKEMIA RELAPSE.

PURPOSE: To report a case of unilateral exudative retinal detachment as the sole presentation of relapsing B-type lymphoblastic leukemia in a 35-year-old man after 3 years of remission. METHODS: Case report. RESULTS: A 35-year-old man in complete remission of high-risk type B acute lymphoblastic leukemia (ALL-B) presented with acute vision loss in his left eye. Exudative retinal detachment was diagnosed at initial evaluation. Hematological and ocular studies were performed. Although there was no evidence of blood, cerebrospinal fluid, or bone marrow disease relapse, transvitreal retinochoroidal cytology identified the infiltration of lymphoblastic leukemic B cells with t(12:21) translocation as the only sign of relapsing ALL-B. CONCLUSION: At first sign of vision loss or ocular symptoms in a patient with a history of lymphoblastic leukemia, and regardless of the hematological findings, exhaustive ophthalmologic exploration and ocular biopsy should be performed without delay-this being crucial for clinical decision making because a prompt diagnosis improves the chances of survival.

Aplicación de la Ley de Dependencia en los pacientes con baja visión / Dependent Care Act application in low vision patients

Introducción. La Ley de Dependencia surge en España como un reto de la política social, cuyo objetivo es atender las necesidades de las personas que requieren apoyo para realizar las actividades esenciales de la vida diaria. El objetivo de este estudio es conocer las características de la población que se encuentra en situación de dependencia por el padecimiento de una afección oftalmológica. Material y métodos. Estudio descriptivo transversal a partir de la entrevista personal y revisión de la historia clínica de un grupo de pacientes atendidos en Consultas Externas del Servicio de Oftalmología del Hospital Clínico Universitario de Valencia, partiendo de los datos vertidos por un cuestionario adaptado a partir de la Encuesta de Discapacidades, Deficiencias y Estados de Salud realizada por el Instituto Nacional de Estadística. Resultados. La media de edad de los pacientes es de 65,8 años, mayoritariamente mujeres y laboralmente activos, con una edad media al inicio de la discapacidad de 59,1 años. Predominó la afección corneal como diagnóstico y la enfermedad común como etiología. La media de la agudeza visual fue de 0,4. Más de la mitad de los pacientes presentaron una situación clínica que podría empeorar con el tiempo. La mayor parte de los pacientes no había solicitado ayuda alguna. Conclusiones. Los pacientes estudiados siguen el mismo perfil poblacional que los estudios precedentes sobre prevalencia de la dependencia. Sería necesario adoptar medidas para mejorar la información que reciben los pacientes sobre sus derechos en este marco, facilitar los trámites burocráticos para la percepción de ayudas, disminuir el tiempo de demora en la valoración de la situación de dependencia y reforzar los dispositivos asistenciales para las personas dependientes(AU)

Introduction. The recent Promotion of Personal Autonomy and Care for Dependent Persons Act has opened up the opportunity to complete the social welfare system generated for the dependent and, perhaps only partly, to change the system of social networks that has meant, until now, their only support. The main goal of the present study is to know the characteristics of dependent people with low vision, the level of dependency and the personal, family and social impact of this situation. Materials and methods. Descriptive cross-sectional study after personal interview and clinical records review of a group of patients belonging to the Ophthalmology Service of the Hospital Clínico Universitario of Valencia. It is based on the results of an adapted questionnaire from the Disability, Deficiency and Health Survey conducted by the Spanish National Statistics Institute. Results. The mean age of the patients was 65.8 years, mostly women and occupied, with a mean age of 59.1 years at the beginning of the disability. The prevailing diagnose was corneal pathology and common disease as etiology. The mean visual acuity was 0.4. Clinical status of over 50% of the patients could worsen within time. Most of the patients had not applied for any assistance. Conclusion. The studied patients follow the same demographic profile as shown on previous studies over dependency. Facilities for paperwork issues, information, evaluation and assistance should be implemented in order to improve the attention to dependent people(AU)

A comparative study of six European databases of medically oriented Web resources.

OBJECTIVES: The paper describes six European medically oriented databases of Web resources, pertaining to five quality-controlled subject gateways, and compares their performance. METHOD: The characteristics, coverage, procedure for selecting Web resources, record structure, searching possibilities, and existence of user assistance were described for each database. Performance indicators for each database were obtained by means of searches carried out using the key words, "myocardial infarction." RESULTS: Most of the databases originated in the 1990s in an academic or library context and include all types of Web resources of an international nature. Five databases use Medical Subject Headings. The number of fields per record varies between three and nineteen. The language of the search interfaces is mostly English, and some of them allow searches in other languages. In some databases, the search can be extended to Pubmed. Organizing Medical Networked Information, Catalogue et Index des Sites Médicaux Francophones, and Diseases, Disorders and Related Topics produced the best results. CONCLUSIONS: The usefulness of these databases as quick reference resources is clear. In addition, their lack of content overlap means that, for the user, they complement each other. Their continued survival faces three challenges: the instability of the Internet, maintenance costs, and lack of use in spite of their potential usefulness.
