Comparison of target-controlled infusion of sufentanil and remifentanil in blunting hemodynamic response to tracheal intubation.

Background: Maintaining blood pressure (BP) and heart rate (HR) after laryngoscopy and tracheal intubation has always been a concern in injured patients. Opioids can attenuate or stop an increase in these two parameters if administered with proper doses or targets in target-controlled infusion (TCI). Remifentanil and sufentanil are widely used for this purpose because their cardiac side effects are low and, especially in traumatic patients, they are tolerated well.

This study aimed to characterize the industrial waste generated by the East Azerbaijan Gas Distribution Company (EAGDC) and to present environmental management strategies. The EAGDC serves 57 cities and 821 villages with a total population of more than 2.

Methods: In this randomized clinical trial, 150 subjects undergoing PRK were allocated into 3 groups. In addition to the routine regimen, pregabalin 75 mg, gabapentin 300 mg, and placebo were administered 3 times daily for 3 days, in groups 1, 2, and 3, respectively.

Effects of degree-biased transmission rate and nonlinear infectivity on rumor spreading in complex social networks.

We introduce a generalized rumor spreading model and analytically investigate the spreading of rumors on scale-free (SF) networks. In the standard rumor spreading model, each node has an infectivity equal to its degree, and connectivity is uniform across all links. To generalize this model, we introduce an infectivity function that determines the number of simultaneous contacts that a given node (individual) may establish with its connected neighbors and a connectivity strength function (CSF) for the direct link between two connected nodes.

The investigation of kinetic and isotherm of fluoride adsorption onto functionalize pumice stone.

Rhazes viewpoints about causes, diagnosis, treatment and prognosis of gout.

Gout, a medical condition of acute inflammatory joint disorders, has been recognized from the antiquity. However, the name of Rhazes, a Persian historic physician who has described the etiology, signs, symptoms, epidemiology, treatment and prevention of this malady more than a thousand year ago, hasn't been taken into consideration appropriately. In this article, we studied and reported several chapters of Alhawi which is considered the most important Rhazes's medical textbook, focussing on his hypotheses because he has described this disease more manifestly.

Cholangiocarcinoma in magnetic resonance cholangiopancreatography and fascioliasis in endoscopic ultrasonography.

Fascioliasis is a worldwide zoonotic infection with Fasciola hepatica and Fasciola gigantica. The zoonoses are particularly endemic in sheep-raising countries and are also endemic in Iran. Typical symptoms that may be associated with fascioliasis can be divided by phases of the disease, including the acute or liver phase, the chronic or biliary phase, and ectopic or pharyngeal fascioliasis.

Incidence of postpartum haemorrhage in women receiving therapeutic doses of low-molecular-weight heparin: results of a retrospective cohort study.

Background Low-molecular-weight heparin (LMWH) is the drug of choice to prevent venous thrombosis in pregnancy, but the optimal dose for prevention while avoiding bleeding is unclear. This study investigated whether therapeutic doses of LMWH increase the incidence of postpartum haemorrhage (PPH) in a retrospective controlled cohort. Methods All pregnant women who received therapeutic doses of LMWH between 1995 and 2008 were identified in the Academic Medical Center, Amsterdam, The Netherlands.

Correlation between creatinine clearance and Helicobacter pylori infection eradication with sequential and triple therapeutic regimens: A randomised clinical trial.

Background And Study Aims: Uraemic patients show susceptibility to gastrointestinal mucosal lesions and colonisation by Helicobacter pylori (HP). Antibiotic resistance constitutes a problem in treatment and bismuth preparations are toxic in uraemic patients. This study aimed to assess the correlation between creatinine clearance (CrCl) and eradication of HP infection with new sequential and standard triple therapeutic regimens.

mtDNA variation of the critically endangered hawksbill turtle (Eretmochelys imbricata) nesting on Iranian islands of the Persian Gulf.

Genetic diversity of sea turtles (hawksbill turtle) was studied using sequencing of mitochondrial DNA (mtDNA, D-loop region). Thirty dead embryos were collected from the Kish and Qeshm Islands in the Persian Gulf. Analysis of sequence variation over 890 bp of the mtDNA control region revealed five haplotypes among 30 individuals.

Prevalence of sexual abuse among patients seeking general urological care.

Introduction: Sexual abuse (SA) history can be found in the backgrounds of an important fraction of men (8-10%) and women (12-25%). Until now there are no data about this prevalence within a urological patient population.

Aim: To establish the prevalence of SA among men and women visiting a urological outpatient clinic and to assess their opinion on screening for SA by urologists.

Elevated serum level of bilirubin is a common manifestation which is occurred in several diseases. Hyperbilirubinemia can manifest either conjugated or unconjugated. Conjugated or direct hyperbilirubinemia usually are caused by hepatocellular diseases or cholestatic liver diseases.

Target-controlled infusion anesthesia with propofol and remifentanil compared with manually controlled infusion anesthesia in mastoidectomy surgeries.

Target-controlled infusion (TCI) system is increasingly used in anesthesia to control the concentration of selected drugs in the plasma or at the site of drug effect (effect-site). The performance of propofol TCI delivery when combined with remifentanil in patients undergoing elective surgeries has been investigated. Our aim in this study was to assess the anesthesia profile of the propofol and remifentanil target controlled infusion (TCI) anesthesia as compared to the manually controlled infusion (MCI), in mastoidectomy surgery, where a bloodless field is of utmost importance to the surgeon.
