RESUMO
The differential diagnosis of scrotal pain and swelling in adolescent males includes testicular and appendage torsion, epididymitis, epididymo-orchitis, trauma and incarcerated hernia. Physical examination, ultrasound and urinalysis often can identify the etiology of the scrotal pain and swelling. We present a case of left scrotal pain and swelling that was initially concerning for a paratesticular mass. Repeat examination and further imaging during pre-operative assessment was consistent with left-sided vasitis. The diagnosis of vasitis is difficult with ultrasound and commonly requires CT or MRI to differentiate from incarcerated inguinal hernia. Recognition of this uncommonly reported condition may prevent unnecessary surgeries.
RESUMO
Cardiovascular disease is a major cause of death worldwide. New diagnostic tools are needed to provide early detection and intervention to reduce mortality and increase both the duration and quality of life for patients with heart disease. Seismocardiography (SCG) is a technique for noninvasive evaluation of cardiac activity. However, the complexity of SCG signals introduced challenges in SCG studies. Renewed interest in investigating the utility of SCG accelerated in recent years and benefited from new advances in low-cost lightweight sensors, and signal processing and machine learning methods. Recent studies demonstrated the potential clinical utility of SCG signals for the detection and monitoring of certain cardiovascular conditions. While some studies focused on investigating the genesis of SCG signals and their clinical applications, others focused on developing proper signal processing algorithms for noise reduction, and SCG signal feature extraction and classification. This paper reviews the recent advances in the field of SCG.
