Functional Outcomes of Stapes Surgery with Titanium and Teflon Prosthesis: Randomized Controlled Trial
Prosthesis material and design is thought to have a role in effective sound transmission, rate of complications and success of stapes surgery. Titanium has been shown to be a promising material in this regard. We compared the intra-operative events, complication rate and the hearing outcomes results of stapes surgery using titanium versus fluoroplastic piston prosthesis.
Efficacy of Vitamin C Vaginal Suppository in Treatment of Bacterial Vaginosis a Randomized Controlled Trial
The aim of the current study was to compare the efficacy and side effects of vaginal vitamin C suppository and vaginal metronidazole in treatment of bacterial vaginosis. Double-blind randomized controlled trial. The study included women who presented to the outpatient gynecological clinic with a diagnosis of bacterial vaginosis by amsels criteria. The included eligible women were randomly allocated in one of two groups: group I, including women who received vitamin C vaginal suppository once daily at bed time for 6 days; and group II, including women who received metronidazole 500 mg vaginal suppository once daily at bed time for 6 days. All included women were reviewed in 8-14 days after completion of treatment for reevaluation.
Peritoneal Dialysis (PD) is one of the 3 well-established modalities of renal replacement therapy used in patients with renal failure. Despite its significant role as a successful method of renal replacement therapy, PD is highly associated with peritonitis and catheter-related infections.
C-MAC Video Laryngoscopy Versus Flexible Fiberoptic Laryngoscopy in Patients with Anticipated Difficult Airway: A Randomized Controlled Trial
Tracheal intubation is one of the most common medical procedures performed in hospitals. On one hand, it is highly successful and easy to perform using a rigid laryngoscope. On the other hand, hypoxic brain damage and death may result rapidly if it is unsuccessful.
Nutrition Research and Human Disease: A Critical Appraisal of Mechanistic Research, Cohort Studies, and Randomized Trials
A major part of nutrition research consists of the investigation of how food components affect the biochemical and physiologicalprocesses within the body. The rationale is that this mechanistic research will lead to a fuller understanding of disease etiology thereby generating information of practical value for the treatment and prevention of disease.
Understanding the Value of Case Reports and Studies in the Context of Clinical Research, Research Design, and Evidence-Based Practice
Case reports and studies may be defined as the non-experimental description of an individual or a few of cases in terms of new or unusual presentation of the diseases, an unexpected disease course or pathophysiology, and new effects (either beneficial or detrimental) of existing medications or procedures. Although they suffer from the non-experimental nature and other potential bias and errors, case reports and studies have played and will continue to play an important part in the advancement of medicine.
