BACKGROUND Anterior pelvic ring surgery includes a variety of plating techniques and insertion of retrograde superior pubic ramus screws. Anterior acetabular surgery also includes fixation through an ilioinguinal or Stoppa approach. These exposures risk injury to the spermatic cord and accompanying genital branch of the genitofemoral nerve. The primary aim of this study was to identify the dist...

Case Report A 19-year-old mother of 2 gave birth to a 3892-g (8 lb, 11 oz) son. The pregnancy of 41 weeks and vaginal delivery were uncomplicated. The baby's Apgar scores were 9 and 10 at 1 and 5 minutes, respectively. On initial examination in the newborn nursery, the infant's scrotum was noted to be purple, indurated, and enlarged to 3 em on the left side. The skin covering the left side of t...

In this study, AZ91 magnesium alloy rods were used to investigate the effects of torsion deformation on microstructure and subsequent aging behavior. Extruded AZ91 rod has a uniform microstructure and typical fiber texture. Torsion deformation can generate a gradient microstructure on the cross-section of the rod. After torsion, from the center to the edge in the cross-section of the rod, both ...

Testicular torsion is a surgical emergency in the field of urology. Knowledge of the epidemiology and pathophysiology is significant to an urologist. However, the epidemiology of testicular torsion in Korea has not been studied. We performed a nationwide epidemiological study to improve knowledge of the epidemiology of testicular torsion. From 2006-2011, the Korean Urologic Association began th...

We present the first upper limit on gravitational wave (GW) backgrounds at an unexplored frequency of 0.2 Hz using a torsion-bar antenna (TOBA). A TOBA was proposed to search for low-frequency GWs. We have developed a small-scaled TOBA and successfully found Ω(gw)(f)<4.3×10(17) at 0.2 Hz as demonstration of the TOBA's capabilities, where Ω(gw)(f) is the GW energy density per logarithmic frequen...

Two cases of bilateral neonatal testicular torsion are reported and combined with 6 previously reported ones. These infants with bilateral testicular torsion are compared with neonates with unilateral torsion. Both have similar signs and symptoms: (1) a swollen bluish-red firm scrotum at birth, and (2) no evidence of spontaneous pain. Infants in neither group had any systemic symptoms. Immediat...

Liposarcoma of the spermatic cord (LSC) is a rare condition characterized by a painless inguinal or scrotal mass. To our knowledge, only about 200 cases have been previously reported in the literature. These tumors are often mistaken for common scrotal swellings, such as hydroceles and hernias. We present a LSC case in which a definitive diagnosis was obtained upon histological examination. We ...

conclusions preoperative diagnosis of spermatic cord leiomyosarcma is difficult and commonly made by histological examination and immunochemical staining. case presentation here we reported a 75-year-old man who presented with a painless lump in the right hemiscrotum. a right radical orchiectomy was performed. histopathology confirmed a neoplastic tissue with mesenchymal origin in spermatic cor...
