BACKGROUND Meniscus tears are the most common injury of the knee. The McMurray's test and Joint line tenderness for diagnosing meniscus tear have been widely tested, but results reported by different authors vary. The wide variations reported have an impact on clinical decision concerning whether to go for other diagnostic tests before going for diagnostic arthroscopy, which is considered as th...

Objective(s) In the last few years, serum procalcitonin has been proposed as an early marker of infections in neonates, with varying results. In this study, we aimed to investigate the value of procalcitonin, and C- reactive protein in establishing the diagnosis of neonatal sepsis. Materials and Methods Blood samples were collected at admission from 69 neonates with suspected infection (admi...

background: müllerian anomalies are associated with infertility. hysteroscopy as the gold standard for evaluating müllerian anomalies is an invasive, expensive and risky procedure which requires enough experience. transvaginal sonography (tvs) and hysterosalpingography (hsg) are less invasive procedures, but there is little known about the accuracy of these tests. the aim of this study was to e...

h.pylori infection stimulates immune responses. these responses at the mucosal level are predominantly of iga types, while circulating antibodies against this microorganism are predominantly igg classes. igm antibodies are rarely found and seem to be non-specific for this bacterium. in this research, water extract antigen, from three strains of h.pylori (isolated from patients with gastritis, d...

background :score, ost and orai risk assessment tools could reduce the cost burden of bmd tests by selecting the high risk patients to osteoporosis. in this study we compared the ability of these risk assessment measures to assess probability of the osteoporosis among post-menopausal women.   methods : 211 post-menopausal women aged 45-88 years enrolled into the study. all of the patients under...

background: urinary tract infection (uti) is one of the most prevalent infectious diseases and escherichia coli is its common cause. the aim of this study was to assess the resistance patterns of e.coli in urinary tract infections and to determine the susceptibility of e.coli to commonly used antimicrobials and also to evaluate the options for empirical treatment of uti. methods: this study was...

introduction: this study is aimed to compare phenotypic test methods and determine antibiotic susceptibility pattern of ampc beta-lactamase producing uropathogenic escherichia coli and klebsiella pneumoniae in clinical isolates. method: e. coli and k. pneumoniae were identified by standard microbiological procedures. screening of ampc beta-lactamase production was done by using cefoxitin disc (...

SUMMARY Within the field of diagnostic tests, the positive predictive value is the probability of being diseased given that the diagnostic test is positive. Two diagnostic tests are applied to each subject in a study and in this report we look at statistical hypothesis tests for large samples to compare the positive predictive values of the two diagnostic tests. We propose a likelihood ratio te...
