Nerve degeneration in inguinal hernia specimens
2011
BACKGROUND: The histological study of the herniated inguinal area is rare in the literature. This report is focused on the detection of structural changes of the nerves within tissues bordering the inguinal hernia of cadavers. Their physiopathological consequences are hypothesized. MATERIALS AND METHODS: Primary inguinal hernia was diagnosed in 30 fresh cadavers. Tissue specimens from the inguinal region close to and around the hernia opening were excised for histological examination. A control of the data was achieved through tissue samples excised from equivalent sites of the inguinal region in 15 cadavers without hernia. RESULTS: The detected nerves in the inguinal area demonstrated path…
Right ventricular involvement in anterior myocardial infarction: a translational approach.
2010
Aims The aim of the present study was to evaluate the involvement of the right ventricle (RV) in reperfused anterior ST-elevation myocardial infarction (STEMI). Methods and results Left anterior descending (LAD)-perfused area (using thioflavin-S staining after selective infusion in proximal LAD artery, %), infarct size (using triphenyltetrazolium chloride staining, %), and salvaged myocardium (% of LAD-perfused area) in the right and left ventricle (LV) were quantified in a 90-min LAD occlusion 3-day reperfusion model in swine ( n = 8). Additionally, we studied, using cardiovascular magnetic resonance, 20 patients with a first STEMI due to proximal LAD occlusion treated with primary angiopl…
Fixation free femoral hernia repair with a 3D dynamic responsive implant. A case series report
2018
Abstract Background To date, no gold standard for the surgical treatment of femoral hernia exists. Pure tissue repair as well as mesh/plug implantation, open or laparoscopic, are the most performed methods. Nevertheless, all these techniques need sutures or mesh fixation. This implies the risk of damaging sensitive structures of the femoral area, along with complications related to tissue tear and postoperative discomfort consequent to poor quality mesh incorporation. The present retrospective multicenter case series highlights the results of femoral hernia repair procedures performed with a 3D dynamic responsive implant in a cohort of 32 patients during a mean follow up of 27 months. Mater…
Dose–volume-related dysphagia after constrictor muscles definition in head and neck cancer intensity-modulated radiation treatment
2014
Dysphagia remains a side effect influencing the quality of life of patients with head and neck cancer (HNC) after radiotherapy. We evaluated the relationship between planned dose involvement and acute and late dysphagia in patients with HNC treated with intensity-modulated radiation therapy (IMRT), after a recontouring of constrictor muscles (PCs) and the cricopharyngeal muscle (CM).Between December 2011 and December 2013, 56 patients with histologically proven HNC were treated with IMRT or volumetric-modulated arc therapy. The PCs and CM were recontoured. Correlations between acute and late toxicity and dosimetric parameters were evaluated. End points were analysed using univariate logisti…
Solitary fibrous tumor surrounding the carotid sheath.
2009
Solitary fibrous tumors (SFTs) are rare spindle cell neoplasms that are mostly found arising from the pleura. Although SFTs recently have been reported in other regions, they are rare in the head and neck and have often been misdiagnosed due to their rarity. SFTs are benign in most cases. Clinically, SFTs usually manifest as wellcircumscribed, slow-growing, smooth and painless masses. Symptoms are often minimal, although they may include sore throat, difficulty in swallowing, change of voice or trismus. CT-Scan and MRI are the most sensitive imaging procedures used. The treatment of choice is complete surgical excision of the lesion. Because recurrences have been noted up to 30 years after …
Detection of Left Ventricular Systolic Dysfunction in Cardiac Amyloidosis with Strain Rate Echocardiography .
2006
Background We examined the potential role of Doppler myocardial imaging including tissue velocity imaging, strain imaging, and strain rate imaging for detection of left ventricular systolic dysfunction in cardiac amyloidosis (CA) and determined the minimum dataset required to make the diagnosis. Methods and Results Doppler myocardial imaging was performed in 103 patients with amyloidosis (AL). Peak longitudinal systolic tissue velocity, systolic strain rate (sSR), and systolic strain (sS) were determined for 16 left ventricular segments. Radial and circumferential sSR and sS were also measured. Patients with increased left ventricular wall thickness were classified with advanced-CA, and the…
Terminal or truncal ligation of the inferior thyroid artery during thyroidectomy? A prospective randomized trial.
2016
Abstract Introduction Thyroidectomy is a common procedure in general and endocrine surgery. The technique of ligation of inferior thyroid artery (ITA) has been invoked as a possible cause of appearance of postoperative hypocalcemia. Methods We performed a prospective randomized study involving 184 patients undergoing total thyroidectomy to evaluate the differences of truncal ligation versus distal ligation of ITA in terms of postoperative hypocalcemia, vocal fold palsy, voice and swallowing impairment. The patients were divided into group A (trunk ligation of ITA) and group B (terminal branches ligation of ITA). Results We evaluated postoperative PTH and calcemia (immediate, 6 and 12 months…
Trocar-related abdominal wall bleeding in 200 patients after laparoscopic cholecistectomy: Personal experience
2006
AIM: To determine the complications and incidence of the first and second access-related vascular injuries induced by videolaparoscopic cholecistectomy. METHODS: We retrospectively reviewed vascular injuries in 200 consecutive patients who underwent videolaparoscopic cholecistectomy from 2003 to 2005. One hundred and one patients with placement of radial expanding trocars were assigned into group A and 99 patients with placement of pyramidal tipped trocars into group B. All the patients were submitted to open access according to Hasson for the first trocar. RESULTS: Bleeding did not occur at the intraoperative cannula-site in group A. However, it occurred at the intraoperative cannula-site …
Effect of Intraperitoneal Sterile Urine Injection on Abdominal Myoelectrical Activity in the Spinal Rat Model
1991
The abdominal muscle reflex contractions in response to intraperitoneal injection of homologous sterile urine and acid, alkaline, hypo- and hyperosmolar solutions are studied in an acute spinal rat model by conventional and integrated electromyographic techniques. Intraperitoneal injection of homologous sterile urine causes a powerful and almost immediate abdominal muscle contracture of relative short duration. This response seems not to be related to urine pH or osmolarity, since only when solutions with extreme variations in these parameters are injected intraperitoneally are significant abdominal muscle contractions observed.
Acute inferior myocardial infarction due to a large thrombus in the Left coronary sinus of valsalva.
2021
Background Masses in the ascending aorta are an uncommon source of coronary embolism: thrombi located on atherosclerotic aortic plaques are the most frequent cause. A floating thrombus, without evidence of ascending aortic pathology has rarely been reported Method We report a case of an unusual aortic route thromboembolism leading ST segment elevation Myocardial Infarction (STEMI). The patient was referred to the Hub Hospital to undergo urgent coronarography. The examination excluded atherosclerotic coronary arteries disease but an unusual persistence of contrast dye was found at the level of non-coronary sinus. The trans-esophageal echocardiography showed a mobile pedunculated echogenic ma…
