Parecoxib frente a ketorolaco en el control del dolor agudo postoperatorio moderado / Parecoxib versus ketorolac for the management of moderate postoperative acute pain

Introducción y objetivos: El parecoxib es un profármaco que tras ser administrado se convierte con rapidez en valdecoxib, un inhibidor selectivo de la cicloooxigenasa 2 (COX-2) y que se administra vía parenteral. Intentamos valorar su eficacia en el tratamiento del dolor postoperatorio de intensidad moderada. Material y métodos: Es un estudio prospectivo, randomizado sobre un total de 96 pacientes intervenidos de: apendicectomías, ooforectomías, hernioplastias y fracturas de cadera entre enero y febrero de 2004. Un grupo recibió parecoxib 40 mg i.v. cada 12 horas (grupo P) y otro ketorolaco 30 mg i.v. cada 8 horas (grupo K). El analgésico de rescate fue paracetamol 1 g i.v. cada 6 horas. Se realizó la escala visual analógica tras 30 minutos de su ingreso en la unidad de recuperación postoperatoria, a las 2, 24 y 48 horas. Resultados: La valoración del dolor a través de la EVA no presentó diferencias entre grupos. La necesidad de analgesia de rescate en el primer día fue del 83,3% (40/48) en el grupo K, frente a un 66,7% (32/48) en el grupo P (p = 0,059). En el segundo día las demandas de analgesia adicional decrecieron. La necesidad de analgesia de rescate fue mayor en los pacientes sometidos a cirugía traumatológica. Los pacientes que recibieron parecoxib mostraron mayor porcentaje de satisfacción de forma significativa. Conclusiones: El control del dolor fue similar para ambos grupos, sin embargo, las pautas analgésicas mostraron limitaciones en el control del dolor, ya que el EVA en las primeras horas y el grado de satisfacción de los pacientes pueden mejorarse. A la vista de los buenos resultados del rescate con paracetamol, la combinación de parecoxib con paracetamol puede ser una mezcla importante en el control analgésico postquirúrgico (AU)

Introduction and objectives: Parecoxib is a pro-drug that after being injected into the body, it is rapidly converted into the active drug valdecoxib, an injectable selective inhibitor of cyclooxygenase 2 (COX-2). Our aim was to determine its effectiveness for the management of moderate postoperative pain. Material and methods: A prospective randomized study was conducted on a total of 96 patients undergoing: appendectomies, oophorectomies, hernioplasties and hip fractures between January and February 2004. One group received parecoxib 40 mg IV each 12 hours (group P) and the other one received ketorolac 30 mg IV each 8 hours (group K). Rescue analgesia was paracetamol 1 g IV each 6 hours. An analogical visual scale was used 30 minutes after admittance to the postoperative recovery unit, and after 2, 24 and 48 hours. Results: Pain was assessed through the VAS scale, with no differences found between groups. The need of rescue analgesia on the first day was 83.3% (40/48) in group K, versus 66.7% (32/48) in group P; (p = 0.059). On the second day, the demand of additional analgesia decreased. The need of rescue analgesia was greater among patients undergoing traumatological surgery. Patients that received parecoxib showed a greater percentage of satisfaction, this difference being significant. Conclusions: Pain management was similar in both groups. However, the analgesic patterns showed limitations in the management of pain, since the VAS score and the degree of satisfaction during the first hours can be improved. Considering the effectiveness of rescue therapy with paracetamol, parecoxib combined with paracetamol may be an useful combination for postoperative analgesic management (AU)

Sugar beet Ca-pectate gel as a cost-effective immobilized-cell matrix for metal biosorption.

Whole bacterial (Pseudomonas putida) and yeast (Saccharomyces cerevisiae) cells were immobilized by entrapment in gel beads of Ca-pectate obtained from sugar beet pulp and gel beads of commercial Ca-alginate (of algal origin). These immobilized-cell particles were tested for Cd2+ removal from dilute aqueous solutions and their mechanical properties were evaluated. Only Ca-pectate gel beads loaded with yeast cells displayed enhanced cadmium-binding efficiency (13.8 mg Cd2+ per g dry matter) as compared to sterile beads (10.7 mg/g). Sterile Ca-pectate gel beads were noticeably more brittle than algal alginate counterparts. The presence of cells reduced the mechanical resistance of both types of beads, however. The practical use of cell-loaded sugar beet Ca-pectate gel as a metal biosorbent is discussed in light of these results.

Leukocyte mean corpuscular volume in the differential diagnosis of acute leukemias.

The leukocyte mean corpuscular volume was measured in 61 cases of acute leukemia. The volume of blast cells allows a clear distinction between lymphoblastic and other varieties of acute leukemia. There seems to be good correlation between patients' age, leukocyte corpuscular volume, cytological and cytochemical findings. Furthermore, myeloblastic leukemias.Leukemic cells can be characterized by their volume, which is close to that of normal cells of the same line. This observation supports the clonal theory of their origin and concurs with the classical nomenclature which separates them into lymphoblastic, myeloblastic and monoblastic types.
