Comparison in Effect of Intravenous Alfentanil and Lidocaine on Airway-Circulatory Reflexes during Extubation
Mustafa Sadegi,Abolfazl Firozian,Mohammad Hossein Ghafari,Fatemeh Esfehani
International Journal of Pharmacology , 2008,
Abstract: This randomized controlled double-blind trial was designed to compare the presence of Airway-Circulatory Reflexes to tracheal extubation in groups administering IV alfentanil or lidocaine, in 150 patients undergoing cesarean surgery receiving a standardized anesthetic protocol. At the end of surgery, after return of spontaneous ventilation, patients received either alfentanil 15 μg kg-1 or lidocaine 1.5 mg kg-1. The presence of cough and it`s severity during emergence before extubation was noted. BP and HR were recorded at 2 min after end of surgery (baseline), 2 min after study drug administration and 1 min after extubation. The groups were matched according to age, baseline BP and HR. The incidence of coughing was less frequent in the alfentanil than in the lidocaine group (19% versus 75%, respectively, p<0.001). Although the severity of coughing was considerably different between two groups (lower in alfentanil g) but was not statistically different (p = 0.292). The mean BP and HR were lower in alfentanil than lidocaine group 2 min after administration and 1 min after extubation (p<0.001). The median of delay time (time between the study drug administration and extubation) was 6 min in alfentanil (Range: 4-8) and 5 min in lidocaine groups (Range: 4-8) (p<0.001). These results indicate that alfentanil decreases Airway-Circulatory Reflexes more than lidocaine during emergence from anesthesia without clinically important prolonging the time to extubation.

International Journal of Pharmacology , 2007,
Abstract: Different additives have been used to prolong spinal anesthesia. We designed a prospective, randomized, double-blind study to evaluate the effect of spinal anesthesia. Eighty patients scheduled for first cesarean surgery were randomly allocated into 2 groups to receive either 1.5 mL lidocaine 5% with 0.5 mL sterile water (control group, n = 40) or 1.5 mL lidocaine 5% with 0.5 mL preservative-free magnesium sulfate 10% (magnesium group, n = 40). Neither epinephrine nor opioid was added to the treatment mixture. The duration of analgesia after spinal anesthesia (the time from local anesthetic injection to the first opioid request) and the duration of analgesia after surgery (the time between termination of the procedure and the time at which the first dose opioid was requested) were compared. The durations of analgesia after spinal anesthesia was significantly longer in the magnesium (160.8±49.1) than in the control group (113.3±27.3) and the durations of analgesia after surgery was significantly longer in the magnesium (74.5±47.5) than in the control group (26.6±25.1), (p = 0.001). There was no associated increase in adverse events in the group receiving intrathecal magnesium.

Clinical Ophthalmology , 2011, DOI: http://dx.doi.org/10.2147/OPTH.S23164
Abstract: rs plana vitrectomy and internal limiting membrane peeling for macular edema secondary to retinal vein occlusion Original Research (3118) Total Article Views Authors: Baharivand N, Hariri A, Javadzadeh A, Heidari E, Sadegi K Published Date August 2011 Volume 2011:5 Pages 1089 - 1093 DOI: http://dx.doi.org/10.2147/OPTH.S23164 Nader Baharivand, Amirhossein Hariri, Alireza Javadzadeh, Ebadollah Heidari, Karim Sadegi Nikookari Eye Hospital, Tabriz University of Medical Sciences, Tabriz, Iran Purpose: To evaluate the effects of vitrectomy and internal limiting membrane peeling for treatment of macular edema secondary to retinal vein occlusion (RVO). Methods: Nine cases of visual loss due to macular edema caused by central retinal vein occlusion or branch retinal vein occlusion underwent pars plana vitrectomy with removal of the preretinal hyaloid, peeling of the internal limiting membrane stained with indocyanine green dye, air–fluid exchange, and postoperative prone positioning. Best-corrected visual acuity (BCVA) and central foveal thickness by optical coherence tomography were measured pre- and postoperatively then compared to assess the outcome of surgery. Results: In all cases intraretinal blood and retinal thickening diminished within 2 months of surgery. Visual acuity improved in all of the central retinal vein occlusion cases and 3/6 branch retinal vein occlusion cases. The decrease in macular thickness was statistically significant (mean postoperative macular thickness 361 ± 61.1 versus mean preoperative macular thickness 563.9 ± 90.0, P = 0.001, t-test). The improvement in BCVA was not statistically significant (mean preoperative BCVA in LogMAR 1.23 ± 0.29 versus mean postoperative BCVA in LogMAR 1.06 ± 0.49, P = 0.09, t-test). Conclusion: In eyes with macular edema secondary to RVO, pars plana vitrectomy with internal limiting membrane peeling can resolve macular edema, but the improvement in BCVA was not statistically significant in this study.

Journal of Cardiovascular and Thoracic Research , 2012,
Abstract: Introduction: Hypertension is the most common medical problem affecting pregnant women during pregnancy contributing to one third of substantial maternal mortality and varieties of fetal and neonatal health problems, while representing health status of a society. This study aimed to investigate the links between a healthy life style and developing hypertension during pregnancy in order to improve healthier behaviors.Methods: In a case-control study from October 2009 to April 2010, physical activity and nutritional practices of two groups of pregnant women (220 in each group) with gestational age of 20 weeks or more, single pregnancy, without any previous medical disorders were compared. Samples in case group had pregnancy induced hypertension. Data were collected using a two-part questionnaire after obtaining informed written consents from mothers before enrollment; later the data were analyzed using the SPSS 13 and Stata software. Results: Women in two groups did not differ regarding their socioeconomic characteristics. There were no significant differences in nutritional practices and level of physical activity in pregnant women of study groups; mean score of physical activity was 54.6±14.8 in test and 57.3±15.0 in control group (P=0.06) and it was 72.9±10.3 and 73.719.5 about nutritional habits in test and control group respectively. Mean pre-pregnancy BMI was higher in case group (P=0.02); these women also had a higher percentage of previous prenatal mortality and history of hypertension.Conclusion: Results state that health during pregnancy is relevant to healthy life style especially preconceptional period; therefore employing proper strategies to improve women knowledge and attitude of the important dimensions of healthy life considering good and healthy diet and active life seem to solve the problem; this needs to unite all health workers to set proper educational programs and courses and support of health policy makers.
The Selection of Proper Auxiliary Parameters in the Homotopy Analysis Method. A Case Study: Uniform Solutions of Undamped Duffing Equation  [PDF]
Mustafa Turkyilmazoglu
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.26105
Abstract: The present paper is concerned with two novel approximate analytic solutions of the undamped Duffing equation. Instead of the traditional perturbation or asymptotic methods, a homotopy technique is employed, which does not require a small perturbation parameter or a large parameter for an asymptotic expansion. It is shown that proper choices of an auxiliary linear operator and also an initial approximation during the implementation of the homotopy analysis method can yield uniformly valid and accurate solutions. The obtained explicit analytical expressions for the solution predict the displacement, frequency and period of the oscillations much more accurate than the previously known asymptotic or perturbation formulas.

Health (Health) , 2012, DOI: 10.4236/health.2012.44034
Abstract: Objective: To discuss the surgical treatment of recurrent osteoma of the mastoid process of the temporal bone, that obstructed external auditory canal causing unilateral conductive hearing loss. Setting: The study was carried out in ENT Clinic, University Clinical Center of Kosovo, Prishtina, Kosovo. Design: Retrospective review of a clinical case. Patient, Intervention and Result: We treated surgically with success a 14-year-old boy with osteoma of mastoid process, obstructing the external auditory canal of the left ear and causing conductive hearing loss. Axial and coronal computed tomography scans revealed an compact bone lesion that obstructed the canal. Complete removal of the lesion was achieved by a retroauricular approach. Conclusion: In order to achieve complete removal of the osteoma, drilling of the lesion must be performed not through the tumor, but around the osteoma, in the surrounding bone tissue.
Alternative Approach to Time Evaluation of Schrodinger Wave Functions  [PDF]
Mustafa Erol
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.311211
Abstract: Time evaluation of wave functions for any quantum mechanical system/particle is essential nevertheless quantum mechanical counterpart of the time dependant classical wave equation does simply not appear. Epistemologically and ontologically considered time dependant momentum operator is initially defined and an Alternative Time Dependant Schrodinger Wave Equation (ATDSWE) is plainly derived. Consequent equation is primarily solved for the free particles, in a closed system, signifying a good agreement with the outcomes of the ordinary TDSWE. Free particle solution interestingly goes further possibly tracing some signs of new pathways to resolve the mysterious quantum world.
Benelli Mastopeksy Scar Revision Using Vertical Mastopexy Insicion: A Case Report  [PDF]
Mustafa Tercan
Modern Plastic Surgery (MPS) , 2013, DOI: 10.4236/mps.2013.31001
Abstract: Minimal or moderate breast ptosis can be treated with Benelli mastopexy technique in experienced hands. Tightening of the periareolar tissue, inappropraite suture usage, excessive tissue removal lead to severe complications in some patients. Patients with these complications is more than difficult to treat breast ptosis. It needs extra tissue to reduce the tensions in patients with wide circumareolar scar tissue and wide areolary complex. Vertical scar mastopexy technique can be used to treat these type of complications as a scar reduction methods.
