Trombosis venosa de retina. Auditoría de un programa de atención especializada / Retinal vein occlusion. Audit of a specialized care program

Background and objectives Retinal vein occlusion (RVO) is the second most frequent cause of retinal vascular disease and is related to classic cardiovascular risk factors. A specific program was designed to detect and treat risk factors in patients with RVO. The aim of this study is to audit the results of this program. Patients and methods The program consisted of a multidisciplinary clinical evaluation by the Ophthalmology and Internal Medicine Departments. All patients with RVO were screened, at minimum, for hypertension, diabetes, dyslipidemia, smoking, overweight, and antiphospholipid syndrome. New risk factors or poor control of known risk factors were expected to be found in at least one-third of the patients. Among them, therapeutic measures were expected to be taken in at least two-thirds. A dissociated automated search of the data of all patients who entered the program between April 2021 and April 2022 was performed. Results Fifty-six patients were included for analysis. Of these, 39 (69.6%) had at least one new or poorly controlled risk factor and 43 (76.8%) had their treatment modified in some way. Antiphospholipid syndrome was detected in five (8.9%). Only one patient had low-risk hereditary thrombophilia. After an exhaustive examination, no risk factors were found in 11 patients. Conclusion This specific program has been effective in detecting new or poorly controlled risk factors and improving their treatment (AU)

Antecedentes y objetivo La trombosis venosa de retina (TVR) es la segunda causa más frecuente de enfermedad vascular de la retina y se relaciona con factores de riesgo cardiovascular clásicos. Se diseñó un programa específico para detección y tratamiento de factores de riesgo en pacientes con TVR. El objetivo de este estudio es auditar los resultados de dicho programa. Pacientes y métodos El programa consistió en una evaluación clínica multidisciplinar por parte de Oftalmología y Medicina Interna. A todos los pacientes con TVR se les realizó cribado, al menos, de hipertensión arterial, diabetes, dislipidemia, tabaquismo, sobrepeso y síndrome antifosfolípido. Se esperó encontrar nuevos factores de riesgo o pobre control de los ya conocidos en, al menos, un tercio de los pacientes. Entre ellos, se esperó tomar alguna medida terapéutica en, al menos, dos tercios. Se llevó a cabo una búsqueda automatizada disociada de los datos de todos los pacientes que entraron en el programa entre abril de 2021 y abril de 2022. Resultados Cincuenta y seis pacientes se incluyeron para el análisis. De ellos, 39 (69,6%) tenían al menos un factor de riesgo nuevo o mal controlado, y 43 (76,8%) vieron modificado en algún modo su tratamiento. Se detectó síndrome antifosfolípido en 5 (8,9%). Solo un paciente tenía una trombofilia hereditaria de bajo riesgo. Tras un examen exhaustivo no se encontró factor de riesgo alguno en 11 pacientes. Conclusión Este programa específico ha sido efectivo para detectar factores de riesgo nuevos o mal controlados y mejorar su tratamiento (AU)

Assessment of Confirmed Clinical Hypersensitivity to Rituximab in Patients Affected with B-Cell Neoplasia.

Rituximab hypersensitivity reactions are rare but are one of the main causes of rituximab elimination from antilymphoma immunochemotherapy treatments. While the clinical picture may be indistinguishable from other infusion-related reactions, hypersensitivity reactions (HSR) do not disappear and instead become more intense with subsequent administrations. Objective. To describe the use of the 12-step protocol for desensitization to intravenous rituximab in clinical practice and the complementary study of a possible IgE-mediated HSR in the context of B-cell lymphoma treatment. Methods. A 12-step rituximab desensitization protocol was performed prospectively within clinical practice in 10 patients with a history of severe infusion reactions or in patients who had a repeated reaction at subsequent doses despite taking more intense preventive measures. Skin prick tests were performed at the time of reaction and at a later time to eliminate false negatives due to possible drug interference. Results. Overall, with the desensitization protocol, 70% of patients were able to complete the scheduled immunochemotherapy. Two patients had to discontinue the therapy due to clinical persistence and the third due to lymphoma progression. Intradermal tests with 0.1% rituximab were positive in only 20% of cases, demonstrating a mechanism of hypersensitivity. Conclusions. The 12-step desensitization protocol is very effective and assumable within healthcare practice. There is a need to determine the mechanism underlying the infusion reaction in a large proportion of cases due to the risk of future drug exposure.

Does the mechanism of injury in pediatric blunt trauma patients correlate with the severity of genitourinary organ injury?

INTRODUCTION: Blunt abdominal trauma can result in injury to genitourinary (GU) organs. Children may be more susceptible to some GU injuries due to anatomic differences compared to adults. Mechanism of injury (MOI) has been thought to relate to both the likelihood and severity of GU injury in children, although this has not definitively been proven. Our purpose was to determine if MOI has any correlation to the severity of GU injury in children treated at our institution. MATERIALS AND METHODS: We reviewed records of all pediatric blunt trauma patients presenting to our institution from January 2005-December 2010 using the LeBonheur Children's Hospital Trauma Registry. All patients with GU injuries were included in this study. Data collected included demographic information, MOI, type and grade of GU injury, associated injuries, and clinical outcome. Continuous variables were tested with ANOVA and categorical variables were tested with chi-square test. RESULTS: Records of 5151 children with blunt trauma were reviewed; 76 patients were found to have GU organ injury. There were 47 males (61.8%) and 29 females (38.2%). Categories of MOI included motor vehicle accident, sports injury, bicycle accident, all-terrain vehicle accident (ATV), pedestrian struck accident, falls, and animal injury. MOI did not have any statistically significant association with the severity of GU organ injury (p = 0.5159). In addition, there was no association between MOI and either gender or side of injury. There was a statistically significant association between MOI and patient age (p = 0.04); older pediatric patients were more likely to experience GU injury due to sports injury and ATV accidents, where as younger patients were more likely to experience GU injury due to pedestrian struck, bicycle accidents or animal bite. CONCLUSIONS: Although specific MOI would seem to relate to presence and severity of injury in children, MOI alone does not correlate with the severity of GU organ injury in our pediatric trauma population. Age of pediatric patients is associated with the type of MOI that results in GU organ injury. The possibility of GU injury should be considered in all symptomatic pediatric patients with clinically significant blunt trauma regardless of the exact MOI.

Design and characterization of biofunctional magnetic porous silicon flakes.

Magnetic porous silicon flakes (MPSF) were obtained from mesoporous silicon layers formed by multi-step anodization and subsequent composite formation with Fe oxide nanoparticles by thermal annealing. The magnetic nanoparticles adhered to the surface and penetrated inside the pores. Their structure evolved as a result of the annealing treatments derived from X-ray diffraction and X-ray absorption analyses. Moreover, by tailoring the magnetic load, the dynamic and hydrodynamic properties of the particles were controlled, as observed by the pressure displayed against a sensor probe. Preliminary functionality experiments were performed using an eye model, seeking potential use of MPSF as reinforcement for restored detached retina. It was observed that optimal flake immobilization is obtained when the MPSF reach values of magnetic saturation >10(-4)Am(2)g(-1). Furthermore, the MPSF were demonstrated to be preliminarily biocompatible in vitro. Moreover, New Zealand rabbit in vivo models demonstrated their short-term histocompatibility and their magnetic functionality as retina pressure actuators.
