background and objective: this study was undertaken to assess the ability of standard urinalysis (ua) and hemocytometer white blood cell (wbc) counts for the diagnosis of urinary tract infection (uti) in patients with urinary symptoms. materials and methods: a total of 600 patients with symptoms of urinary tract infection were enrolled in this prospective study. standard ua, hemocytometer wbc c...
Introduction: Spontaneous bacterial peritonitis (SBP) is a prevalent complication in the patients with cirrhosis and ascites, which leads to high intrahospital mortality. Diagnosis is made when ascetic fluid neutrophils is ≥250 cells/mm3. Manual counting of neutrophils is time-consuming, technically difficult, expensive and in many cases individual-dependent. In contrast, automated counting ...
OBJECTIVES/HYPOTHESIS Using a standardized, graded, intraoperative stimulation protocol, we aimed to delineate the effects of various stimulation levels applied to the recurrent laryngeal nerve on the postoperative predictive value of intraoperative nerve monitoring. STUDY DESIGN A total of 917 nerves at risk were included for analysis. Intraoperatively, patients underwent stimulation of the ...
Abstract Background and Objectives: one of the endemic foci for Cutaneous Leishmaniasis in Iran is Mashhad in which limited outbreak have recently been reported. The commonly used method for diagnosis is the clinical features confirmed by direct microspic examination and culture or biopsy. We compared these two tests to determine the level of their sensitivity, specificity and positive predicti...
background: blind percutaneous pleural biopsy has traditionally been performed to investigate the etiology of exudative pleural effusion in which the initial thoracocentesis has been non- diagnostic. in view of the increasing use of image-guided and thoracoscopic pleural biopsies, this study examined the role of blind abrams pleural biopsy in the investigation of the exudative pleural effusion ...
background: currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. the purpose of this study was to evaluate the value of serological parameters including serum pepsinogen i (pgi), pepsinogen ii (pgii) and pepsinogen i: ii ratio for the screening atrophic gastritis and gastric cancer. methods : the study population consisted of 132 dyspeptic patients ...
Preoperative acid studies and early postoperative insulin tests in 275 patients undergoing various forms of vagotomy have been related to recurrent ulceration. Follow-up time has been from two to nine years, mean 4-3 years. Recurrence is directly related to basal acidity in both tests but is not related to stimulated acid levels preoperatively. In the insulin tests higher levels of acidity afte...
Over the past decade, many clinicians have recognized th need to acquire an expanded clinical vocabulary and cot ceptual framework with which to interpret and act upo clinical information from the patient's history, the physic, examination, and the diagnostic laboratory . This expande vocabulary acknowledges the probabilistic nature of clinic events that occur consequent to diagnostic and thera...
BACKGROUND Femoropopliteal bruits indicate flow turbulences and increased blood flow velocity, usually caused by an atherosclerotic plaque or stenosis. No data exist on the quality of bruits as a means for quantifying the degree of stenosis. We therefore conducted a prospective observational study to investigate the sensitivity and specificity of femoropopliteal auscultation, differentiated on ...
