Abstract: Purpose: The main objective of this study was to determine the reliability and concurrent validity of using Modified Sphygmomanometer (sphyg) and body weighing scale to determine the magnitude of pressure and body weight change during digital spinal examination. Subjects: One hundred and twenty apparently healthy subjects were recruited. Methods: Weighing scale was used to measure the body weight of the investigator while Mercury sphygmomanometer was used to measure the pressure exerted. There was test re-test interval of 2 weeks. Data were analysed by descriptive statistic and Pearson product moment correlation. Results: The …result showed that there was significant correlation between the weight change (WC) values obtained on the weighing scale on day 1 and 2 (r=0.91). Also, there was significant correlation between Pressure obtained in the sphygmomanometer on day 1 and 2 (r=0.94). Similarly, there was significant correlation between the WC and Pressure Change (PC), (r=−0.49). The participant's age, height, weight and BMI contributed significantly as predictors for both BWC and PC change respectively. Conclusion: This study concluded that weighing scale and Mercury sphygmomanometer are reliable and valid to determine the magnitude of pressure applied during DPAP. Show more

Abstract: Objective: To examine the feasibility and accuracy of teleconsultation of coronary angiograms using iPhone 4 and FaceTime. Methods: The study was conducted in two stages. Coronary angiograms of 100 patients with single-vessel disease were retrospectively selected by a core laboratory unit and then re-evaluated by a consultant cardiologist on both an iPhone 4 screen via the FaceTime application and on the workstation monitor of the angiography laboratory. The interpretations of the consultant cardiologist on localization and severity of angiographic lesions were recorded and compared with those of the core laboratory. Using the same teleconsultation system, the consultant cardiologist …outside the hospital was presented live angiographic images of 10 patients undergoing primary percutaneous coronary intervention (PCI) for acute myocardial infarction. Results: Interpretations of the consultant cardiologist on the localization and severity of 100 lesions on both the smartphone screen and workstation monitor showed high levels of agreement with the results of the core laboratory (for all, κ > 0.80). Of 10 patients whose PCI was performed under live video teleconsultation, eight patients underwent successful PCI while two patients had normal coronary arteries. There was an excellent agreement between the consultant cardiologist and the operator regarding lesion localization. Conclusions: Smartphones allow highly accurate interpretations on angiographic lesions and thus may serve as a supplementary teleconsultation tool in both elective and emergency situations.
