ABSTRACT
Objective@# The short-term clinical effects of two kinds of normal temperature flow root sealers (the calcium silicate-based sealer iRoot SP and the siloxane-based sealer GuttaFlow2) combined with single point filling technology and a frequently-used sealing agent (AH Plus) combined with continuous wave hot tooth filling technology were evaluated. @*Methods @#A total of 279 teeth (656 root canals) were randomly divided into three groups: the iRoot SP group, GuttaFlow2 group and AH plus group. We recorded the filling time of each root canal, collected a digital dental film to evaluate the filling effect of each root canal, and conducted a follow-up visit one week and one month after the operation to record the incidence of pain. We used SPSS 18.0 to analyze the above data. @*Results @# There was no significant difference in the root canal filling effect among the three groups (P > 0.05). There was no significant difference in the filling time between the iRoot SP group and the GuttaFlow2 group (P > 0.05), but the filling time was significantly shorter in the AH Plus group (P < 0.05). There was no significant difference in the postoperative pain between the iRoot SP group and the GuttaFlow2 group (P > 0.05), and the incidence of pain in the iRoot SP group and the GuttaFlow2 group was lower than that in the AH Plus group (P < 0.05).@*Conclusions @# GuttaFlow2 and iRoot SP combined with single point filling technology can save filling time and obtain good clinical effects compared with frequently-used hot tooth filling technology and the incidence of postoperative pain was low.
ABSTRACT
Objective To evaluate the effect of hypothermia status in the donors upon the renal graft function after renal transplantation from donation after citizen's death. Methods Thirty-six eligible donors were randomly divided into the normal temperature (body temperature 36.5-37.5 ℃ , n=19) and hypothermia groups (body temperature 34.0-35.0 ℃ , n=17). The matched recipients undergoing renal transplantation were also assigned into the normal temperature (n=38) and hypothermia groups (n=34). Perioperative conditions of the donors and recipients were compared between two groups. And postoperative renal graft function of the recipients were statistically compared between two groups, including the incidence of delayed graft function (DGF) and primary nonfunction (PNF). Results No statistical significance was identified in the perioperative amount of urine volume, serum creatinine (Scr), systolic blood pressure, saturation oxygen, warm ischemia time and cold ischemia time of the donors between two groups (all P>0.05). No statistical significance was noted in terms of the operation time, intraoperative mean blood glucose and intraoperative mean arterial pressure of the recipients between two groups (all P>0.05). Postoperative incidence of DGF of the recipients in the hypothermia group was 6%, significantly lower than that in the normal temperature group (24%) (χ2=4.393, P=0.036). Postoperative incidence of PNF of the recipients was 3% in both the hypothermia and normal temperature groups with no statistical significance (χ2=0.000, P=1). Conclusions The hypothermia status of the donors can significantly reduce the incidence of DGF, whereas exerts no evident effect upon the incidence of PNF in the recipients.
ABSTRACT
Se realizó un estudio descriptivo, prospectivo, de corte transversal a 500 pacientes adultos que asistieron al policlínico "5 de Septiembre" de Consolación del Sur, en el primer semestre del año 2007, con el objetivo de demostrar que no existe variación en el leucograma en la etapa febril y post-febril. Se les realizó un conteo global y diferencial de leucocitos por el método tradicional existente en el momento en que la temperatura corporal se encontraba elevada y en la etapa post-febril del proceso. Para el procesamiento de la información se utilizaron los medios computarizados simples y para la significación estadística la técnica de (Ji_cuadrado) y prueba de comparación de proporciones. De la muestra estudiada el 56,4 %, se encontraban febrículas, 206 tenían fiebre propiamente dicha y sólo el 2,4 % presentaban hiperpirexia, 235 pacientes presentaban cifras de leucocitos dentro de los parámetros establecidos como normales, la leucocitosis ligera predominó en un 48,6 %, seguido de la moderada en un 3,8 %. Predominó la neutrofilia en un 40,8 %, la linfocitosis en un 24 % y existió un bajo por ciento de eosinófilos, monocitos y células jóvenes; no existieron diferencias significativas en los resultados de este complementario en ambas etapas. El tiempo de espera de los pacientes en los cuerpos de guardias a la normalización de la temperatura corporal, osciló desde 30 minutos hasta 2 horas y más. Se diseña una estrategia de capacitación al personal médico sobre este tema.
A descriptive, prospective and cross sectional study with 500 patients attending at "5 de September" Outpatient Clinic in Consolacion del Sur during the first term of 2007 was conducted. This study was aimed at demonstrating that no variation is observed in leukogram during febril and post-febril stage. A Global and differential count of leukocytes was performed by means of the traditional method while the temperature was elevated and during post-febril stage. Simple computerized tools were used to collect the information and for the statistical significance chi-square method and the test for the comparison of proportions. Out of the sample studied 56,4% had slight fever, 206 presented fever and only 2,4% presented hyperpyrexia, 235 patients presented leukocyte counts in the normal parameters established, slight leukocytosis prevailed in a 48,6% followed by moderate in 3,8%. Neutrophilic leukocytosis predominated in a 40, 8%, and lymphocytes 24%; a low percent of eosinophiles, monocytes and young cells was observed; during both stages no significant differences were found in the results of this complementary analysis. The waiting time of the patients in the emergency room to reach the normal temperatures was between 30 minutes to 2 hours and more. A strategy to train medical personnel about the topic is designed.
ABSTRACT
Objective To introduce operative skill of liver resection by blocking hilum of liver under normal temperature.Method Retrospective analysis of experience treating 86 cases of liver cancer with the operation.Result Among 86 cases of hepatic malignant tumor,there were not serious complications such as death,massive haemorrhage etc.during operation;postoperative liver failure occurred in 7 cases,among them,cure 5 cases and 2 cases of death.The incision infection occurred in 5 patients;The thorax dropsy occurred in 19 cases, which was absorbed by oneself after treating in 14 cases,cured by puncture occurred in 5 cases.Conclusion Operative skill of blocking hilum of liver under normal temperature is more ideal means in treating the liver cancer.
