Abstract
Background: Intravaginal misoprostol has been shown to be an effective agent forcervical ripening and induction of labor. The aim of present study was to assess the effects of adding hyoscine to vaginal misoprostol on its success rate.
Methods: In a clinical trial, 74 women who were referred to undergo legal induction of labor during first pregnancy trimester in Arash Hospital, in Tehran, Iran, between March 2006 and March 2007 were enrolled, and were randomly divided in to two groups of misoprostol (400 μg/4h, vaginal) (n=37) or misoprostol (400 μg/4h, vaginal) plus hyoscine (20 mg IV) (n=37). Their complications including nausea, vomiting, fever, abdominal pain, need for analgesics, diarrhea, vaginal bleeding, decline in hemoglobin more than 3 g/dl, need for blood transfusion and failure of treatment according to the failure of induction of labor or cervical opening in 24 hours after starting treatment and the total duration of hospitalization were compared between groups. Results: There were no significant differences between groups regarding the rate of side effects like nausea, abdominal pain and vaginal bleeding. In misoprostol plus hyoscine group, the success rate in abortion was significantly higher (40.5% vs. 18.9%, p=0.04) and total duration of hospitalization were significantly lower (1.16±0.41 vs.
1.42±0.45 days, p=0.01). There was no case of fever, need for blood transfusion or significant vaginal bleeding in both groups.
Conclusions: Adding 20 mg hyoscine via IV rout to vaginal misoprostol will raise the success rate in induction of abortion, and decreases the total duration of hospitalization without adding adverse effects.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a common and mostly chronic mental health condition that affects children, adolescents, and adults. Stimulants and atomoxetine are first-line agents for the treatment of ADHD. Despite the impressive track record of stimulants in the treatment of ADHD, they fail in 25% of patients due to lack of efficacy or the emergence of unwanted side effects. Accordingly, this study carried out to compare efficacy and safety of duloxetine (a serotonin and norepinephrine reuptake inhibitor) and methylphenidate (a short acting stimulant) in the treatment of children with attention-deficit/hyperactivity disorder.
Methods: Twenty-four children diagnosed with ADHD participated in this 6 weeks open clinical trial. Patients were between 6 to 11 years old that had been referred to psychiatry clinic at Akhavan and Rofide Medical and Rehabilitation Center in Tehran from September 2012 to July 2014. Diagnosis was made by two child psychiatrist according to DSM-IV TR criteria. Thirteen patients received duloxetine and others received methylphenidate. Conner’ parent rating scale-revised-short form (CPRS-RS) and ADHD-rating scale (ADHD-RS) were used at the beginning and then each two weeks to assess efficacy of treatment. Routine laboratory tests and electrocardiogram (ECG) was carried out in the beginning and end of the trial.
Results: Twenty children with ADHD completed the study (Ten in methylphenidate and ten in duloxetine group). In both groups, scales of CPRS-RS and ADHD-RS were reduced from baseline to endpoint, but this reduction in methylphenidate group was significantly greater than duloxetine group (P= 0.000). The most common side effect was gastrointestinal problems in duloxetine group and anorexia in methylphenidate group. No serious side effects and no changes in laboratory and ECG indexes were seen in both groups.
Conclusion: Duloxetine is not efficacious as well as methylphenidate in treatment of children with ADHD. Although more research are needed to achieve more accurate results.

Abstract
Blood transfusion is commonly implemented to manage life and health-threatening conditions on a rapid and short-term basis. Over the years, ongoing technical advances have dramatically improved transfusion medicine to provide more safety and effectiveness. However, transfusion is still complicated with different adverse events that mainly induced by the presence of allogeneic leukocytes in the blood products. Several lines of evidence have shown that leukocytes in blood components are involved in the induction of febrile nonhemolytic transfusion reactions (FNHTRs), HLA alloimmunization and platelet refractoriness as well as the increased risk of the infectious diseases transmitted by leukotropic viruses including cytomegalovirus (CMV), human T-lymphotropic virus (HTLV)-I/II and Epstein-Barr virus (EBV). During current decades, introducing various leuko-reduction techniques have shown to be associated with less transfusion related adverse events and improved clinical outcomes. The lower incidence and severity of febrile transfusion reactions; reduced risk of transfusion related transmission of CMV or other leukocyte-associated infections, lowered incidence of alloimmune platelet refractoriness in addition to reducing risk of mortality and morbidity in patients are considered as clinical benefits of leuko-reduced products. Currently, by the use of 3rd and 4th generation of filters, the highest levels of leukoreduction in blood components have been achieved. Filtration techniques have also the advantages of being performed shortly after preparation of components (pre-storage) or post-storage even at the patient’s bedside. However, it seems that pre-storage depletion of leukocytes provides better protection than post-storage techniques due to the elimination of leukocyte-derived cytokines effects which are increasingly released during storage. Particularly in platelet products, the earlier depletion of leukocyte also favors less platelet-induced leukocyte activation which may be triggered by the interaction between either activated platelets or their released chemokines and residual leukocytes during storage. Despite the benefits attributed to leukoreduction of blood components, the global use of leukoreduced products is commonly hampered by its high cost especially in developing countries in which leukoreduction of blood components is usually limited to some patients with special conditions. In this review, after briefly introducing of some transfusion adverse events that are attributed to allogeneic leukocytes existed in blood products, the effects of leukoreduction process in the attenuation of these events will be discussed.
