The aim of the present study was to analyze the diagnostic accuracy of the commonly used provocative tests in the diagnosis of lateral epicondylitis (LE). Cozen's test, Mills test and Maudsley test are most widely used. Till date no studies have been reported on the diagnostic accuracy of these tests. Musculoskeletal ultrasonography serves as a gold standard tool in the diagnosis of LE. Thirty subjects participated in the study. Baseline measurements of pain severity, elbow joint mobility, hand grip strength and three provocative tests were recorded by the principal investigator. A second investigator accompanied the subjects for musculoskeletal ultrasonography who was blinded of the test results. The thickness of common extensor tendon, echo texture and lateral epicondyle bony contour was measured. The test results of the three provocative tests with ultrasonographic findings were analyzed. The sensitivity for Cozen's test, Maudsley test and Mills test was found to be 84%, 88% and 53% respectively. The specificity for Cozen's Maudsley and Mills test was found to be 0%, 0% and 100% respectively. Mills test showed significant area under receiver operator curve (ROC) i.e. (0.769), which explains that the test has good diagnostic accuracy. This validation study, concludes that Mills test has an excellent diagnostic value for ruling in LE.

Objectives: Hydronephrosis is commonly detected during antenatal scans. There are multiple conflicting prognostic factors in the literature with no clear focus on the postnatal outcome. The aim of the study is to assess the outcome of fetal hydronephrosis, based on antenatal sonography.Materials and Methods:Based on the third trimester fetal ultrasound findings, patients were divided into group I (unilateral hydronephrosis) and group II (bilateral hydronephrosis, ureteric dilatation, bladder thickening, etc). Postnatal evaluation and follow-up was performed by a single physician with uniform protocol. The outcomes, spontaneous resolution vs. surgical intervention, were compared between groups. Among group I, further analysis of outcome was done based on 32-week fetal pelvic antero posterior diameter (APD).Results: Among a total of 116 patients in the study group; group I had 78 patients, 7 (9%) required surgery; group II had 38 patients, 21(55%) required surgery. The difference in outcome between the groups was statistically significant (P = 0.002). Among those with unilateral hydronephrosis, none (0/55) with APD <15 mm required surgery, while all patients (4/4) with fetal APD> 30 mm required surgery. In those with APD between 15-30 mm, 3/19 required surgery and prolonged follow-up was required to arrive at the decision. The difference in outcome between the subgroups was statistically significant (P< 0.001, Chi-square test).Conclusions:The results of our study show that simple unilateral fetal hydronephrosis runs a benign course. In the presence hydronephrosis larger than 15 mm, bilateral disease, or bladder distension, detailed postnatal evaluation and regular follow-up is warranted to plan a timely intervention. The above data could be used in prenatal counselling of these parents. Further larger studies are warranted to through more evidence.
