The sonographic features of male breast lesions, which underwent ultrasound examination in our hospital for the past 10 years, were retrospectively analyzed. Sonographic features of these lesions were standardized as BI-RADS image lexicon. The differences in ultrasonic malignant signs were assessed between the benign and the malignant diseases. Between the two groups, incomplete boundary was statistically different. The specificity was above 95% within the two groups in terms of speculated margin, echogenic halo, calcification, axillary lymphadenopathy, thickening of skin and eccentric of mass to the nipple. High-frequency sonographic examination has a high level of differential diagnosis for male breast lesions.
Objective To explore the effect of self-designed early rehabilitation procedure of frozen shoulder incorporating high-frequency ultrasound technology in the outpatient treatment of patients with early frozen shoulder. Methods One hundred and eighty-two consecutive patients who attended the outpatient clinic of the Department of Rehabilitation Medicine of the First Affiliated Hospital of Xinjiang Medical University and were diagnosed with frozen shoulder between January 2018 and May 2021 were selected and randomly divided into the trial group and the control group, with 91 patients in each group. Patients in the trial group received early rehabilitation procedures for frozen shoulder, and patients in the control group received conventional physiotherapy. The Visual Analogue Scale (VAS) (including VAS score for resting pain and VAS score for active motion), active range of motion of the shoulder joint (external rotation, forward flexion, and abduction), Shoulder Pain and Dysfunction Index (SPADI) (including pain subscale score, dysfunction subscale score, and total score) were compared between the two groups before treatment (Week 0) and 4 and 8 weeks after the start of treatment (Week 4 and 8). Results A total of 143 patients (74 in the trial group and 69 in the control group) completed the study. There was no significant difference in any assessment index between the two groups in Week 0 (P>0.05). The results of the within-group comparison after treatment showed that the VAS score for resting pain (F=44.359, P<0.001), VAS score for active motion (F=158.458, P<0.001), anterior shoulder flexion (F=123.334, P<0.001), abduction mobility (F=117.539, P<0.001), total SPADI score (F=133.814, P<0.001), SPADI pain subscale score (F=74.093, P<0.001), and SPADI dysfunction subscale score (F=145.336, P<0.001) in Week 4 and 8 were better than those in Week 0, and the assessments in Week 8 were better than those in Week 4 in each group (P<0.05); in the control group, there was no statistically significant difference in the external rotation mobility of the shoulder in Week 4 compared with that in Week 0 (P=0.599), and the external rotation in Week 8 improved significantly compared with that in Week 0 (P<0.001), whereas the external rotation of the shoulder in Week 4 and 8 in the trial group improved significantly compared with that in Week 0 (P<0.001). The results of the between-group comparison after treatment showed that the two groups had statistically significant differences in resting shoulder pain VAS score (F=93.712, P<0.001), active motion VAS score (F=103.565, P<0.001), external shoulder rotation (F=13.388, P<0.001), anterior shoulder flexion (F=66.375, P<0.001), abduction mobility (F=110.253, P<0.001), total SPADI score (F=7.917, P=0.006), and SPADI pain subscale score (F=39.091, P<0.001); the SPADI dysfunction subscale score was lower in the trial group than that in the control group in Week 4 (P=0.002), but by Week 8 there was no statistically significant difference between the two groups (P=0.352). Conclusion The early rehabilitation program for frozen shoulder incorporating high-frequency ultrasound technology is more effective than conventional physiotherapy in the intervention of patients with early frozen shoulder, and may provide a referenceable example for the combined application of high-frequency ultrasound technology and physiotherapy.
