The purpose of this paper is to determine whether there is a difference in the postoperative corneal astigmatism and uncorrected visual acuity UCVA as well as best corrected visual acuity BCVA between 2 types of clear corneal incisions used in phacoe
mulsification: the superior and on the steepest clear corneal incision.
This study included 40 patients with cataract and mild to moderate corneal astigmatism (0.50 D - 2.00 D) who underwent phacoemulsification with foldable posterior chamber lens (with 3.2mm corneal incision). Patients were randomly divided into two groups: superior clear corneal incision group SCCI (20 eyes) and on the steepest clear corneal incision group OCCI (20 eyes). Measurements included corneal astigmatism by Keratometry, UCVA and BCVA. These Measurements were taken on first day,1 week, 2 weeks,1, 2,3 and 6 months. The mean preoperative corneal astigmatism was (1.24 D ± 0.44),(1.25 D ± 0.44) in superior corneal incision group, and on the steepest corneal incision group, respectively. After 6 months postoperatively, the mean corneal astigmatism was (1.53 D ± 0.49) in SCCI group, (1.03 D± 0.39) in OCCI group, with statistically significant difference (p<0.001).There was statistically significant difference in UCVA. But there was no statistically significant difference in BCVA.
The paper concludes that compared with SCCI, the OCCI could correct some corneal astigmatism
Protection against cardiac ischemia/reperfusion injury is the basic objective in open heart surgery, and it may be achieved by pharmacological preconditioning or Postconditioning. In this study, we aimed to compare the effects of two different anest
hetic techniques (inhalation and total intravenous anesthesia) on ischemia-reperfusion injury in Coronary Artery Bypass Graft surgery. 80 CABG patients were randomly assigned into one of tow groups: Group A Sevoflurane (n=40) and Group B total intravenous anesthesia (n=40) with Propofol . data of hemodynamic monitoring and inotrops using were recorded. Arterial blood samples were taken in the preoperative period (T0), 12th hours (T1) ,24th hours (T2) and 48th hours postoperatively, and Troponine I levels were measured . The time of ventilation, ICU and total hospitalization were recorded .
Postoperative levels of troponine I were significantly lower in the Sevoflurane group with less using of inotrops and less staying in the ICU post-op . We conclude that the use of a volatile anesthetic regimen in CABG surgery associate with better preservation of myocardial function and a reduced postoperative release of
troponine I.
Purpose: To evaluate and compare the pharmacological characteristics and clinical efficacy of two topical steroid prednisolone preparations (Redmond®, prednisolone acetate 1%; and Pred Forte®, prednisolone acetate 1%) in reducing postoperative inflam
mation in patients having phacoemulsification surgery with IOL implantation, which will support our trust in national products considering it's availability and lower costs compared with universal products.
Methods:
I- Laboratory Study: Direct microscopic examination of the ophthalmic suspension for both formulations.
II- Clinical Study: This study was interventional, prospective, randomized controlled study included 60 eyes of patients undergoing emulsification surgery with IOL implantation. Patients were assigned to one of two treatment groups, The first group (30 eyes) received Redmond® while the second group (30 eyes) received Pred Forte® in addition to standard therapy. Study drug was administered postoperatively every 2 hours while awake for 7 days, then four times daily for 7 days, then twice daily for 7 days, then once daily for 7 days. Clinical efficacy was compared for differences in visual acuity, anterior chamber cells (scale 0-4), fundus and macula, drug's ocular adverse effects: foreign body sensation and irritation (scale 1-3), and intraocular pressure (IOP). Results were compared on day 1, day 3, 1 week, 2 weeks, and 1 month postoperatively.
Results:
I- Average particle size in ophthalmic suspension for both formulations was (< 1 μm). (Redmond® = 0.95 μm, Pred Forte® = 0.77 μm).
II- No statistical differences in clinical efficacy or safety were seen between the two formulations tested at any time point evaluated with respect to visual acuity, anterior chamber cells, fundus and macula, foreign body sensation and irritation, and intraocular pressure (IOP).
Conclusions: In this study of routine cataract patients, both prednisolone acetate 1% formulations are comparably effective and safe when administered for the reduction of inflammation after phacoemulsification surgery with IOL implantation. Direct microscopic examination showed that both formulations achieved the condition that particle size in ophthalmic suspension must be less than one micron.

This study was carried out in the department of anesthesia and reanimation at
Alassad ,Tishreen university Hospitals , Lattakia , Syria , during the year 2014-2015 , and
included 45 patients of either sex (5-15 kilogram of weight ) undergoing lower
abdominal
and urologic procedures.
Patients were divided into three groups :
Patients of group A : received spinal anesthesia by using combination between
bupivacaine (0.4 mg/kg ) and normasaline (placebo) .
Patients of group B : received spinal anesthesia by using combination between
bupivacaine (0.4 mg/kg ) and fentanyl (0.2 mcg/kg ) .
Patients of group c : received spinal anesthesia by using combination between
bupivacaine (0.4 mg/kg ) and fentanyl (0.6 mcg/kg ) .
The goal of the study is studying the effects of combination between fentanyl and
bupivacaine in the spinal anesthesia for the children whom prepared to subumblical
operations .
Conclusion :
Combination between fentanyl and bupivacaine reduced to use postoperative
narcotics and increased the duration of spinal anesthesia, in addition to provided
hemodynamic stability during the operation.
The injection of needle is an action of fear and pain, especially for young children , so it is important that we resort to a method of pain-free when applying the local anesthesia.
