METHODS: The local ethics committee approved this retrospective study and for this type of study formal consent is not required. A total of 42 B3 lesions in 40 women aged 41-77 years were included in our study. All patients underwent CESM 2-3 weeks after the biopsy procedure and surgical excision was subsequently performed within 60 days of the CESM procedure. Three radiologists reviewed the images independently. The results were then compared with histologic findings.

RESULTS: The sensitivity, specificity, and positive and negative predictive values for confirmed demonstration of malignancy at CESM were 33.3%, 87.2%, 16.7%, and 94.4% for reader 1; 66.7%, 76.9%, 18.2%, and 96.7% for reader 2; 66.7%, 74.4%, 16.7%, and 96.7% for reader 3. Overall agreement on detection of malignant lesions using CESM among readers ranged from moderate to substantial (κ = .451-.696), for categorization of BPE from moderate to substantial (κ = .562-.711), and for evaluation of lesion intensity enhancement from fair to moderate (κ = .346-.459).

METHODOLOGY: Tracheal aspirates were obtained from neonates on ventilatory support. The SM test was carried out on specimens of tracheal aspirate immediately after collection. Levels of SP-A in tracheal aspirates were determined by enzyme-linked immunosorbent assay (ELISA) method. The results of the SM test and SP-A level of the tracheal aspirates were compared against the clinical diagnosis of RDS based on clinical, radiological and bacteriological findings.

RESULTS: Both the median microbubble counts (6 microbubbles/mm2, range = 0-90) and median SP-A levels (100 micrograms/L, range = 0-67447) of infants with RDS were significantly lower than those of infants with no obvious lung pathology (P < 0.0001), and pneumonia (P < 0.0001). The SM test of tracheal aspirates had higher overall accuracy for the diagnosis of RDS than measurement of SP-A levels (94.6% vs 82.4%). When the receiver operating characteristic (ROC) curves of both tests for RDS were compared, the area under the ROC curve of the SM test was larger (0.9689) than that of the SP-A method (0.8965).

METHODS: This prospective study was carried out on 561 term-gestation jaundiced neonates in two Malaysian hospitals. Venous blood sample was collected from each neonate for contemporary measurement of TSB by hospital laboratories and Bilistick. TAT was the time interval between specimen collection and TSB result reported by each method.

Methods: This is a retrospective study done on all patients who presented with acute scrotal pain from January 2013 to December 2017. The data collected included the patient's age, symptoms, the time duration between the onset, ultrasound, and surgery, ultrasound findings with Doppler and the surgical intervention. Statistical analysis was performed using SPSS 25.0. Data are presented as mean (SD) values. Differences between groups and predictive values were calculated using Chi-square, t-test and Mann-Whitney U-test and are expressed by value with 95% CI.

Results: The total number of patients who presented with acute scrotal pain were 88. Testicular torsion was diagnosed in 55 (62.50%) of the patients, 17 (19.32%) had epididymis-orchitis, 5 (5.68%) had torsion of appendage/cyst, and 11 (12.50%) had normal testis. Ultrasound has a sensitivity and specificity of 88.24% and 68.40% respectively. It is a good tool to detect testicular torsion but it is operator dependent. Positive predictive value was 83.33% and negative predictive value was 76.47%. When ultrasound is combined with clinical findings the rate of negative exploration is reduced by 10%.
