Methicillin-resistant Staphylococcus aureus is the major cause of healthcare-associated bacteremia in most of Hospital and it increased risk of infection, morbidity and mortality especially, when associated vancomycin resistance in same infection. In this study 42 S. aureus were isolated from wound infection patients in Diwaniya hospital and S. aureus was isolated by selective medium out form 50 swab samples. The PCR assay was used for direct detection of methicillin (mecA) and vancomycin (van) antibiotics resistance gene in 42 S. aureus isolates. The results show only 5 isolates (11%) were have single methicillin resistance and there no single vancomycin resistance in all isolates. While the PCR results show there found 3 isolates (7.1%) were have association resistance methicillin and vancomycin resistance. But all methicillin resistance was 12 isolates (19%). In conclusion, we conclude that PCR assay can be used as highly sensitive and specific in detection of methicillin and vancomycin resistance gene, and Vancomycin-resistant can be associated with Methicillin resistance in Staphylococcus aureus isolated from wound infection.

Statement of problem: In dentistry, the acrylic resins are the common materials used for fabrication of removable dentures to restore function, appearance, etc. However, such restorative substances have to be lacking some physical properties. The aim of the current study to assess the effect of zinc oxide filler on some physical properties of heat cured acrylic resin. A total of 40 acrylic specimens were fabricated. Depending on the type of test, they were divided into water sorption and porosity groups. For each group, 20 specimens were reinforced with zinc oxide particles at 1% by weight and the others were considered as control. The porosity and water sorption tests were carried out for each specimen. The specimen’s data were analyzed and comparison was made by independent t test. The results showed that there was a slightly reduction in water sorption and porosity after incorporation of zinc oxide filler. In conclusion; the addition of ZnO powder to heat cured acrylic resins affects slightly their physical properties.

Urinary stone disease is a major health care problem due to its high prevalence and incidence. The aim of the study is to evaluate the safety and efficacy of ESWL lithotripsy as a primary modality of treatment for upper ureteric stones. From October 2011 to October 2016, 400 patients (300 male and 100 female) with upper ureteral stones were admitted to Al-Diwaniya teaching hospital, urology unit and enrolled in this study, their age range from 18 to 65 years with a mean age of 40 ± 3 years. All patients were evaluated by history, physical examination, laboratory investigation (including urinalysis, full blood count, coagulation profile and renal function tests). The stone size, location, opacity and degree of obstruction were assessed by preoperative radiographic imaging studies, including KUB, ultrasound and computerized tomography (CT scan). The overall stone-free rate at three months was 95% (380/400). Clearance after first sitting was 70% (280/400), after second sitting was 20% (80/400) and after third sitting was 5% (20/400). Clearance of stone in patients with stone size ≤ 1 cm was 97% (388/400), and in patients with stone size > 1cm was 5% (340/400). Five per cent (20) of cases did not have successful outcome. In conclusion, the results of our study show that ESWL as a primary modality for upper ureteric stones treatment has an overall success rate of 95%. Success rate drops with increasing size of stone, duration of stone in ureter, and no anesthesia is required.
