Background: Despite the fact that abdominal ultrasound has been widely used in many centres in Tanzania as a primary diagnostic imaging for patients with abdomino-pelvic lesions, its diagnostic utility has not yet been assessed in Tanzania, and therefore its use as an alternative diagnostic tool in patients with abdomino-pelvic lesions is not justified. This study aimed to determine the utility of abdominal ultrasound in the diagnosis of abdomino-pelvic lesions in our local setting.Methods: This was a cross sectional study to evaluate the diagnostic utility of abdominal ultrasound in patients presenting with abdomino-pelvic lesions at Bugando Medical Centre between January 2017 and July 2017. Abdominal ultrasonographic findings were cross-tabulated against operative findings (the gold standard). Then, the sensitivity, specificity, accuracy, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and accuracy were calculated to determine the diagnostic utility of abdominal ultrasound.Results: A total of 146 patients (M: F ratio = 1: 2.2) were studied. The mean age at diagnosis was 39.3 years. The diagnostic utility of abdominal ultrasound in terms of sensitivity, specificity, PPV, NPV and accuracy were 39.4-100%, 0-100%, 64.7-100%, 0-100% and 40.8-100% respectively.  The kappa statistic (қ) showed good to excellent agreement with the operative findings, the gold standard (қ = 0.75-1.00).Conclusion: The diagnostic utility of abdominal ultrasound in detecting abdomino-pelvic lesions is much lower than that seen in developed countries, hence, abdominal ultrasound is not a reliable tool in detecting abdomino-pelvic lesions at Bugando Medical Centre and therefore its use should be supplemented with abdominal CT scan in selected cases.

D Dimer

Background: We evaluated the diagnostic efficacy of tissue plasminogen activator (tPA), using an enzyme-linked immunosorbent assay (ELISA) and compared it with an ELISA D-dimer (VIDAS D-dimer) in acute pulmonary embolism (PE). Patients and methods: We studied 127 consecutive outpatients with clinically suspected PE. The diagnosis of PE was based on a clinical probability pretest for PE and a strict protocol of imaging studies. A plasma sample to measure the levels of tPA and D-dimer was obtained at enrollment. Diagnostic accuracy for tPA and D-dimer was determined by the area under the receiver operating characteristic (ROC) curve. Sensitivity, specificity, predictive values, and the diagnostic utility of tPA with a cutoff of 8.5 ng/mL and D-dimer with a cutoff of 500 ng/mL, were calculated for PE diagnosis. Results: PE was confirmed in 41 patients (32 %). Areas under ROC curves were 0.86 for D-dimer and 0.71 for tPA. The sensitivity/negative predictive value for D-dimer using a cutoff of 500 ng/mL, and tPA using a cutoff of 8.5 ng/mL, were 95 % (95 % CI, 88–100 %)/95 % (95 % CI, 88–100 %) and 95 % (95 % CI, 88–100 %)/94 %), respectively. The diagnostic utility to exclude PE was 28.3 % (95 % CI, 21–37 %) for D-dimer and 24.4 % (95 % CI, 17–33 %) for tPA. Conclusions: The tPA with a cutoff of 8.5 ng/mL has a high sensitivity and negative predictive value for exclusion of PE, similar to those observed for the VIDAS D-dimer with a cutoff of 500 ng/mL, although the diagnostic utility was slightly higher for the D-dimer.
