Dose Sildenafil Citrate Reduce the Incidence of Emergency Cesarean Section and Fetal Distress During Labor? A Randomized Double-Blinded Clinical Trial.

Background: Fetal distress (FD) is one of the most frequent causes of emergency cesarean section (CS) due to the insufficient uteroplacental blood supply during labor. There is a theory that Sildenafil citrate (SC) may improve the uteroplacental blood supply and decrease fetal hypoxia and FD.

Methods: In a randomized double-blinded clinical trial, a total of 208 low-risk subjects who met our stringent inclusion criteria were randomly assigned into two groups: the Sildenafil citrate group (n=104) and the placebo group (n=104).

Clinical and historical features of cesarean scar pregnancies in a tertiary hospital with a high rate of cesarean section: A case-control survey.

Background And Aims: Cesarean scar pregnancy (CSP) is a rare medical condition accounting for 1:2000 of all pregnancies with prior history of cesarean deliveries (CS). As the rate of CS is increasing worldwide, it is important to know the nature of CSP and its complications.

Methods: In this retrospective case-control study, we evaluated 264 pregnant women; 86 cases with ultra-sonographic findings of CSP and 178 controls: normal pregnancies with gestational age less than 12 weeks.

The aim of this study was to determine the results of pectoralis major rupture repair with Achilles tendon allograft in bodybuilding athletes.

Methods: In this case series study, 22 bodybuilding athlete patients (24 pectoralis major ruptures) were undergone open surgical repair during January 2016 till December 2020.

Role of suprascapular nerve block in idiopathic frozen shoulder treatment: a clinical trial survey.

Background: Several therapeutic methods have been proposed for frozen shoulder syndrome. These include suprascapular nerve block, a simple and cost-effective technique that eliminates the need for nonsteroidal anti-inflammatory drug therapy.

Methods: This was a clinical trial that included patients with unilateral shoulder joint stiffness.
