Learnings from real-life experience of using omalizumab for chronic urticaria in Latin America.

BACKGROUND: Updated urticaria guidelines recommend that patients should be assessed for disease activity, severity, control, and quality of life at baseline and follow up. Regarding treatment, guidelines consider second generation antihistamines as the cornerstone in therapy for chronic urticaria (CU), while other drugs, such as omalizumab, are conceived as second-line alternatives. In regards to omalizumab, despite advances in the management of CU, there are still open questions about timing, dosing, and objective measures for clinical response. This study was designed to portray the use of patient-reported outcomes (PROs) in chronic urticaria management, as well as the effectiveness and treatment patterns of omalizumab in CU, as seen in a real-life setting in Latin America. METHODS: This is a retrospective observational study, involving 72 Latin American patients with chronic urticaria treated with omalizumab. Patient reported outcomes and treatment patterns, response, quality of life improvement and discontinuation were analyzed. RESULTS: From the 72 patients, 91.7% (n = 66) were assessed through PROs, where urticaria control test (UCT) was the most used (79.2%; n = 57). Overall, 80.0% (n = 44) responded to omalizumab at some point of the treatment. Omalizumab 300 mg was associated with earlier response compared to lower doses. Regardless of dosage, most patients assessed with CU-Q2oL improved quality of life (80.8%; n = 21). With respect to omalizumab discontinuation, 20.8% (n = 15) patients interrupted omalizumab before the 3rd month of treatment (p = .000). CONCLUSIONS: The present study highlights how the use of PROs and omalizumab in Latin America differ from guidelines' recommendations and clinical trials. Even though most patients were initiated under omalizumab 300 mg, most of them finished with lower doses. Regardless of dosage, most patients responded to omalizumab and improved quality of life at some point during treatment. However, such features were seen earlier with omalizumab 300 mg. Regarding treatment discontinuation, one-fifth of patients interrupted omalizumab before the third month.

Técnica de recuperación acelerada (fast-track) aplicada a cirugía protésica primaria de rodilla y cadera. Análisis de costos y complicaciones / Fast-track recovery technique applied to primary total hip and knee replacement surgery. Analysis of costs and complications

Objetivo. Determinar el ahorro económico que supone la implantación de un sistema de recuperación rápida (fast-track) al compararlo con el método de recuperación convencional en artroplastia primaria de cadera (ATC) y rodilla (ATR). Asimismo, determinar si existen diferencias entre ambos en el índice de complicaciones. Material y métodos. Estudio retrospectivo descriptivo, incluyendo 100 artroplastias primarias utilizando el método fast-track y 100 utilizando recuperación convencional. Las variables comparadas entre ambos grupos fueron edad, sexo, índice de comorbilidad de Charlson, ASA, estancia media, complicaciones intrahospitalarias y durante los primeros seis meses e índice de reingresos y transfusiones. Se determinó el coste global para cada procedimiento y por día de ingreso, y el ahorro se calculó según la reducción de la estancia media. Resultados. Ambos grupos fueron comparables en cuanto a edad, sexo, ASA e índice de Charlson. La reducción de la estancia media hospitalaria fue de 4,5 días para el grupo de ATR y 2,1 días para el de ATC. El ahorro calculado fue de 1.266 euros para el grupo de ATR y de 583 euros en el de ATC. No se observaron diferencias significativas en cuanto a complicaciones intrahospitalarias, necesidad de transfusiones, reingresos y complicaciones durante los primeros 6 meses. Discusión. Existen pocos trabajos de análisis de costos en relación con la implantación de sistemas de recuperación rápida en cirugía protésica. Diversas series publicadas tampoco observaron un mayor índice de complicaciones utilizando este método. La utilización del método fast-track representó un ahorro de 1.266 euros para el grupo de ATR y de 583 euros para el grupo de ATC sin aparente repercusión sobre el índice de complicaciones (AU)

Purpose. To determine the cost reduction and complication rates of using an enhanced recovery pathway (Fast-track) when compared to traditional recovery in primary total hip replacement (THR) and total knee replacement (TKR), as well as to determine if there were significant differences in complication rates. Material and methods. Retrospective review of 100 primary total arthroplasties using the Fast-track recovery system and another 100 using conventional recovery. Gender, Charlston comorbidity index, ASA score, length of stay and early complications were measured, as well in-hospital complications and those in the first six months, re-admissions and transfusion rates. The total and daily cost of stay was determined and the cost reduction was calculated based on the reduction in the length of stay found between the groups. Results. Both groups where comparable as regards age, gender, ASA score, and Charlston index. The mean reduction in length of stay was 4.5 days for TKR and 2.1 days for THR. The calculated cost reduction was 1266 euros for TKR and 583 euros for THR. There were no statistically significant differences between groups regarding in-hospital complications, transfusion requirements, re-admissions and complication rates in the first six months. Discussion. There are few publications in the literature reviewed that analyse the cost implications of using fast-track recovery protocols in arthroplasty. Several published series comparing recovery protocols found no significant differences in complication rates either. The use of a fast-track recovery protocol resulted in a significant cost reduction of 1266 euros for the TKR group and 583 for the THR group, without affecting complication rates (AU)

Detection of diabetic foot hyperthermia by infrared imaging.

In diabetic foot, the occurrence of an ulcer is often associated with hyperthermia. Hyperthermia is defined as a temperature greater than 2.2°C in a given region of one of the foot compared to the temperature of the same region of the contralateral foot. Unfortunately, hyperthermia is not yet assessed in current diabetic foot therapy. In this paper, we propose an easy way to detect a possible hyperthermia by using an infrared camera. A specific acquisition protocol of the thermal images is proposed. A dedicated image analysis is developed: it is composed of a contour detection of the 2 feet using the Chan and Vese active contour method associated to the ICP rigid registration technique. Among 85 type II diabetes persons recruited in the Dos de Mayo hospital in Lima, Peru, 9 individuals show significant hyperthermia. It is expected that the new possibility of detecting hyperthermia in hospitals or in diabetic health centers which is now available, thanks to the proposed method, will help in reducing foot ulcer occurrence for diabetic persons.
