BACKGROUND Validation of voltage-based scar delineation has been limited to small populations using mainly endocardial measurements. The aim of this study is to compare unipolar voltage amplitudes (UnipV) with scar on delayed enhancement cardiac magnetic resonance imaging (DE-CMR). METHODS Heart failure patients who underwent DE-CMR and electro-anatomic mapping were included. Thirty-three end...

endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity. endometriosis can sometimes occur in a previous surgical scar. scar endometriosis is rare and difficult to diagnose. it mostly follows obstetrical and gynecological surgeries. this condition is often confused with other surgical conditions. we are reporting one case of scar endometriosis invol...

laryngeal leiomysarcoma is an extremely rare malignancy originating from smooth muscle cells. its rarity is due to the fact that only less than 50 cases of pure laryngeal leiomyosarcoma and less than 10 cases of hypopharyngeal leiomyosarcaoma have been reported in modern medical literature.  even though the clinical presentation mimics that of a laryngeal carcinoma forming the major bulk of the...

OBJECTIVE To determine the differences in myelination between the human recurrent laryngeal nerve and superior laryngeal nerve. METHODS Fifteen confirmed laryngeal nerve specimens were harvested from five cadavers. Cross-sections were examined under a photomicroscope and morphometric analysis performed. RESULTS There was a significantly greater number of myelinated fibres than unmyelinated ...

following the first report of laryngeal small cell carcinoma in canada in 1972,only 82 cases of this cancer has been reported in the literature untill 2001.this cancer originates from laryngeal neuroendocrine cells.It,s clinical presentation consists of hoarseness,breathing difficulty:and cigarette smoking is the most important risk factor.this type of cancer is mostly presented after 50 years ...

BACKGROUND The purpose of this study was to evaluate the contribution of laryngeal intraoperative nerve monitoring (IONM) during thyroidectomy in predicting postoperative laryngeal mobility. METHODS Between 2009 and 2012, 127 patients underwent thyroidectomy, during which 216 recurrent laryngeal nerves were stimulated with suprathreshold stimulations. Laryngeal mobility was examined through d...

Scar endometriosis is a rare form of extra-pelvic endometriosis that can occur after surgery involving the uterus. Direct mechanical implantation seems to be the most conceivable theory for scar endometriosis. Patient usually presents with lump and pain at surgical site. Often the diagnosis of endometriosis is not suggested until histology has been performed. We hereby present a case of scar en...

cesarean scar pregnancy (csp) is a rare, but life-threatening type of ectopic pregnancy. an exact and early diagnosis of csp is very important for prognosis. the aim of the present study was to describe 4 women with csp and discuss their clinical presentations, diagnoses, and various management options along with the published literature. four women with a suspicion of csp or cervical pregnancy...

Laryngeal schwannomas are rare, benign tumors, most often arising from the superior laryngeal nerve. We describe a case of a 68-year-old female with a laryngeal schwannoma of the recurrent laryngeal nerve after traumatic injury. We postulate that trauma to the recurrent laryngeal nerve during thyroidectomy or thyroplasty incited growth of a nerve sheath tumor. This is the first reported case of...

objective (s): scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. this study evaluates the translational capacity of four of physical injury models to induce scar formation around the sciat...
