Three-wavelength broadband soot pyrometry technique for axisymmetric flames.

Soot temperature measurements in laminar flames are often performed through two-color broadband emission pyrometry (BEMI) or modulated absorption/emission (BMAE) techniques, using models to relate the ratio between flame intensities at two different wavelengths with soot temperature. To benefit from wider spectral range and increase the accuracy of experimental estimation of soot temperature, this work proposes a new approach that uses three-color broadband images captured with a basic color camera. The methodology is first validated through simulations using numerically generated flames from the CoFlame code and then used to retrieve soot temperature in an experimental campaign. The experimental results show that using three-color and BEMI provides smoother reconstruction of soot temperature than two-color and BMAE when small disturbances exist in the measured signals due to a reduced experimental noise effect. A sensitivity analysis shows that the retrieved temperature from three-color BEMI is more resilient to variations on the ratio of measured signals than BMAE, which is confirmed by an error propagation analysis based on a Monte Carlo approach.

Effects of body weight-support treadmill training on postural sway and gait independence in patients with chronic spinal cord injury.

OBJECTIVE: To examine the effects of a six-week body weight-support treadmill training (BWSTT) program on center-of-mass control and gait independence in chronic, incomplete spinal cord injury (iSCI) patients. DESIGN: Descriptive. SETTING: Clinica Los Coihues. Neurorehabilitation center in Santiago, Chile. PARTICIPANTS: 17 chronic iSCI patients and 17 healthy subjects. OUTCOME MEASURES: An instrumented sway (ISway) test was performed before and after the implementation of a six-week BWSTT program. The standing balance of participants was measured by Normalized jerk (NJ) and root mean square (RMS). These values were used to assess the standing balance of participants, and were correlated with the scores obtained on the Walking Index Spinal Cord Injury (WISCI) II test. RESULTS: Significant differences were found in standing balance (i.e., through NJ) after the BWSTT program (P = 0.016), but no significant differences were found in RMS values for postural sway (P = 0.693). None of the patients obtained improved WISCI II scores pre- vs. post-intervention. CONCLUSION: While a BWSTT program can improve center-of-mass control in iSCI patients, no effects were recorded for gait independence. TRIAL REGISTRATION: National Clinical Trials, registry number NCT02703883.

[Anticonvulsant Hypersensitivity Syndrome: A Case Report]. / Síndrome de hipersensibilidad a los anticonvulsivos: reporte de un caso.

DRESS syndrome (skin reaction with eosinophilia and systemic symptoms) is an idiosyncratic drug reaction characterized by rash, fever, lymphadenopathy, and internal organ dysfunction. This case report is on a patient with bipolar affective disorder who presented with a systemic inflammatory response associated with the use of valproic acid, and an important activation of symptoms when used with other drugs with a different pharmacological action mechanism. The diagnosis of DRESS syndrome is primarily by exclusion, and its detection may be difficult, which could potentially become fatal for the patient.

Síndrome de hipersensibilidad a los anticonvulsivos: reporte de un caso / Anticonvulsant Hypersensitivity Syndrome: A Case Report

El síndrome de reacción cutánea con eosinofilia y síntomas sistémicos (DRESS) es una reacción idiosincrásica a medicamentos que se caracteriza por erupción cutánea, fiebre, linfadenopatía y disfunción de órganos internos. Se revisa el caso de una paciente con trastorno afectivo bipolar (TAB) que sufrió una respuesta inflamatoria sistémica asociada al uso de ácido valproico y, además, tuvo una importante reactivación de los síntomas al usar otros medicamentos cuyos mecanismos de acción farmacológicos son diferentes. El diagnóstico de DRESS es principalmente de exclusión, por lo que puede tardarse en detectarlo y terminar en una entidad potencialmente mortal.
