Termólisis facetaria por radiofrecuencia en el dolor dorso lumbar crónico / Facet radiofrequency thermolysis in chronic thoracolumbar pain

Objetivo: Evaluar la seguridad de la termólisis facetaria por radiofrecuencia en el tratamiento del dolor dorsolumbar crónico. Materiales y métodos: Entre julio de 2013 y julio de 2014, se analizaron retrospectivamente 12 pacientes con dolor dorsolumbar crónico de tipo facetario, a los que se les había realizado previamente un bloqueo bajo tomografía computada (TC). Se evaluaron las complicaciones inmediatas y tardías, registrándose también la mejoría de síntomas de forma directa (escala visual analógica) e indirecta (consumo de medicación). Resultados: Hubo menos de un 20% de complicaciones tempranas leves, todas autolimitadas. No se constataron complicaciones tempranas graves ni tardías. A los tres meses del procedimiento se confirmó un descenso del dolor en el 83% de los casos (n = 10), con una supresión total de la ingesta de medicamentos en un 25% (n = 3) y una reducción de la misma en un 58% (n = 7) de los pacientes. Discusión: A pesar del número reducido de pacientes de nuestro estudio, los resultados en cuanto a la seguridad y el éxito del procedimiento fueron muy similares a los reportados en otros trabajos con mayor casuística. La mejora se vio reflejada no solo en la reducción del dolor, sino también en la menor ingesta de analgésicos. Conclusión: La termólisis facetaria por radiofrecuencia es un método seguro y útil, con un bajo porcentaje de complicaciones que pueden manejarse ambulatoriamente

Objective: To evaluate the safety of facet-dependent radiofrequency thermolysis for the treat-ment of chronic thoracolumbar pain. Materials and methods: A retrospective analysis was performed on 12 patients with chronic thoracolumbar pain of facet type, who had previously undergone a radicular blockage using computed tomography (CT), in the period between July 2013 and July 2014. Inmediateand delayed complications where assessed. Improvement of symptoms was also assessed, both directly (visual analogue scale), and indirectly (reduction in pain relief medication). Results: Self-limited early complications were noted in 20% of the patients. No late nor serious complications were reported. Three months after the procedure was performed, pain relief was observed in 83% of the cases (n= 10), with absolute reduction in pain relief medication in 25% (n = 3) of the patients, and a partial reduction in 58% (n = 7). Discussion: In spite of the reduced number of patients in our study, the results were similar to other publications with larger populations in regard to safety and procedure success. Improvement was not only reflected by the reporting of reduced pain, but it was also observed in a reduced intake of pain relief medications. Conclusión: Our study shows that facet-dependent radiofrequency thermolysis is a safe and useful method, with low complication rates, that can be managed on an outpatient basis

Assessment of the quality of dna extracted by two techniques from Mycobacterium tuberculosis for fast molecular identification and genotyping

We report a comparative study of two DNA extraction techniques, thermolysis and chemical lysis (CTAB), for molecular identification and genotyping of M. tuberculosis. Forty DNA samples were subjected to PCR and the results demonstrated that with thermolysis it is possible to obtain useful data that enables fast identification and genotyping.

A Clinical Effects between Ellman Surgitron(R) Thermolysis and Argon Laser Thermoablation in Trichiasis

PURPOSE: To determine the therapeutic effect between Ellman Surgitron(R) thermolysis and Argon laser thermoablation in patients with trichiais. METHODS: Thirty-one patients (46 eyes) were analyzed. We performed Argon laser thermoablation in 23 patients (35 eyes) and Ellman Surgitron(R) thermolysis in 8 patients (11 eyes). Mean age was 54. Mean follow-up period was 11 months in Ellman Surgitron(R) group, 46 months in Argon laser group. RESULTS: In Argon laser group, 17 cases of 13 patients were performed successfully in first procedure (48.6%), and cumulative success rate was 68.6% after second procedure. Eleven eyes of 6 patients (31.4%) were performed more than three times or needed to surgical intervention. On the other hand, in Ellman Surgitron(R) group, 7 cases of 5 patients (63.6%) were successfully performed in first procedure, and second procedure makes all patients allowed to be successful in treatment of trichiasis. In all two groups, complications such as lid defect, granulation tissue formation, continuous pain and erythematous skin lesions were not found. CONCLUSIONS: The success rate of Ellman Surgitron(R) thermolysis is higher than Argon laser thermoablation, and all patients in Ellman Surgitron(R) group were treated within second procedure without recurrence. The above results suggest that Ellman Surgitron(R) thermolysis is one of the good methods to treat trichiasis.

Synthesis and Properties Study of Ternary Complex of Rare Earth with L-Leucine and Imidazoles / 中国药房

OBJECTIVE:To synthesize ternary complex of rare earth with L-Leucine and imidazoles and to determine its properties.METHODS:The ternary solid complex was synthesized from the reaction of rare earth chlorate with L-Leucine and imidazoles in the medium of alcohol,and the compositional analysis,properties,mechanism of thermolysis,thermostability and the bacteriostatic action of the ternary complex were studied by chemistry analysis,chemical elements analysis,infrared spectral(IR)analysis,molar conductivity measurement and derivative thermogravimetry(TG-DTG)analysis,bioactivity experiments etc.RESULTS:The constitute structure of the ternary complexes was detected to be electrolyte1∶3type RE(Leu) 3 Im(H 2 O)Cl 3 ?2H 2 O,meanwhile,the thermolysis dynamics,thermostability and the bacteriostatic action against E coli of the ternary complex were established preliminarily.CONCLUSION:The composition and the property of the ternary complexes are stable and which were found to be of good bacteriostatic action in the preliminary examination.
