Acinetobacter baumannii is a gram-negative aerobic bacterium that can be found in different environments, such as food, containing vegetables, meat, and fish,moreover, it can be present in soil and freshwater. A. baumannii has globally considered an opportunistic nosocomial bacterium in the healthcare setting contributing to increased morbidity and mortality. The current study aimed to detect the aminoglycoside genes in A. baumannii isolated from different clinical causes. In total, 20 isolates of A. baumannii were obtained from different clinical cases. Bacterial isolate DNA was extracted using a DNA extraction kit. Quantus Fluorometer was used to detect the concentration of the extracted DNA in order to detect the goodness of samples. 1 μ, l of DNA and 199 μ, l of diluted QuantiFlour Dye were mixed. After 5 min incubation at room temperature, DNA concentration values were evaluated, and following the initial amplification of the A. baumannii aada1 gene, 20 μ, l of PCR product with F and R primers were sent to Sanger sequencing. The results of the antimicrobial susceptibility revealed that A. baumannii isolates were resistant to Gentamicin (95%), Amikacin (90%), and Tobramycin (60%). Molecular investigation of the aadA1 and AAC (3)-IV genes exhibited that the aadA1 gene was detected in 15% of the isolates. However, the AAC (3)-IV gene was not detected in any of the isolates. The gel electrophoresis revealed that the molecular weight of the aadA1 gene was 490bp. The DNA sequence of the aadA1 gene was conducted in this study, and the results exhibited no mutations in all isolates.

Background and Objective: Migraines are the third most prevalent diseases and the seventh most debilitating diseases in the world. Medical treatment options for acute migraine episodes are various while none are infinitely effective for all patients. The aim of the present study was to compare fixed combination of acetaminophen, aspirin and caffeine with ibuprofen (AAC) with ibuprofen. Materials and Methods: This double-blind clinical trial (Registration No. IRCT2017052930680N4) was performed upon patients attending the neurology clinic at Shahid Mostafa Khomeini General Hospital with complaint of headache. Treatment protocol for this study consisted of 2 medications prescribed for 4 consecutive episodes: Ibuprofen 400 mg and AAC tablets. Each patient received two sets of medication each for two episodes of headaches consisting of 2 of each drug. Pain perception was evaluated by 11-point Box Scale at three stages: prior to administration of the medication, and 2 and 6 hours after taking the medications and daily functions of the patient were assessed 6 hours after administering the medications by filling the Behavioral Rating Scale (BRS-6) which is a clinical assessment tool. Results: Results of this study demonstrated that difference in severity of pain after taking 2 Ibuprofen tablets and AAC in the first and second episodes of migraine was statistically significant. Furthermore, AAC as compared to Ibuprofen, helped considerably more by allowing patients to regain enough focus to continue their daily life (P=0. 001). Conclusion: The results of this study showed that in patients with migraine, AAC is more effective than ibuprofen on improving patient's function and reducing pain.
