Rats, mice, and hamsters are commonly used laboratory rodents in the experimental modeling strategies of avulsion-induced motoneuron degenerations. It is necessary to study the species-specific gene expression in spinal cord in response to avulsion. We carried out the brachial roots avulsion in all animals and compared the survival and nNOS gene expression in injured motoneurons and spinal segm...

INTRODUCTION Complete ureteral avulsion is one of the most serious complications of ureteroscopy. The aim of this report was to look for a good solution to full-length complete ureteral avulsion. CASE PRESENTATION A 40-year-old man underwent ureteroscopic management. Full-length complete avulsion of ureter occurred during ureteroscopy. Pyeloureterostomy plus greater omentum investment outside...

OBJECTIVE To study whether avulsion and ballooning are independent risk factors for symptoms and/or signs of pelvic organ prolapse. DESIGN Retrospective analysis of data obtained in clinical practice. SETTING Tertiary urogynecology unit. POPULATION Seven hundred and sixty-one consecutive women with symptoms of pelvic floor dysfunction. METHODS Evaluation included history, vaginal examin...

We describe three cases of retronychia; a chronic case where total nail avulsion had to be performed since the inflammation persisted after proximal nail avulsion and the first two cases of retronychia on an early clinical stage successfully treated with partial nail avulsion. We also describe the first two cases of retronychia appearing after a chemical matricectomy, occurring on the same pati...

Our previous studies have demonstrated that some male patients suffering from brachial plexus injury, particularly brachial plexus root avulsion, show erectile dysfunction to varying degrees. However, the underlying mechanism remains poorly understood. In this study, we evaluated the erectile function after establishing brachial plexus root avulsion models with or without spinal cord injury in ...

Tooth trauma continues to be a common problem that every dental surgeon must be prepared to assess and treat when necessary. One of the serious traumatic injuries is avulsion where one or more teeth come out of the alveolar socket. Tooth avulsion is an emergency for children and adolescents requires management approaches for the survival of avulsed teeth. The objective of this article is aimed ...

Background As the triangular fibrocartilage complex (TFCC) anchors the distal radius to the ulna via the radioulnar ligament (RUL), a severely displaced distal fragment of the radius may be associated with a foveal avulsion of the TFCC. The purpose of this retrospective study was to assess, radiographically and arthroscopically, the relationship between displacement of the radius, the ulnar sty...

Avulsion of the optic nerve is an infrequent traumatic event which results in a permanent and usually devastating loss of vision. We present two cases which highlight the salient features of partial and complete optic nerve avulsion. The clinical findings, including the results of B-scan ultrasonography, fluorescein angiography, and computed tomography (CT) are discussed. In addition, the past ...

Flexor digitorum profundus (FDP) tendon avulsion is a common injury in sports. This is secondary to forced extension against flexor digitorum profundus contraction. However, avulsion injury of the FDP tendon secondary to an enchondroma of the distal phalanx is extremely rare. There have only been three previous reports of such an occurrence. This report describes a fourth case of an avulsion in...
