Use of topical tranexamic acid in primary total hip arthroplasty. Efficiency and safety. Our experience.
2019
Abstract Background and aim Intravenous tranexamic acid has been shown to reduce bleeding and the need for transfusions in total hip arthroplasty, although it has a theoretical risk of producing thromboembolic phenomena. Recently some papers have been published using the topical application of tranexamic acid, but the ideal administration protocol has not yet been clearly defined. The aim of this paper was to demonstrate that our protocol of topical tranexamic acid is effective and safe. Methods Prospective data collection from a case series of 80 primary hip arthroplasties, in which the following topical tranexamic acid protocol is used: 1.5 g diluted to a total volume of 60 ml were admini…
Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.
2005
PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…
Predictive value of the balloon expulsion test for excluding the diagnosis of pelvic floor dyssynergia in constipation
2003
Abstract Background & Aims: The aim of this study was to establish a simple method to exclude the possibility of pelvic floor dyssynergia (PFD) in constipated patients and thus avoid unnecessary expensive physiologic studies. Methods: Patients with suspicion of functional constipation (FC) were studied prospectively between 1994 and 2002, excluding those with severe systemic, psychological, or symptomatic anorectal/colonic disorders or taking medications that might modify symptoms or results of studies. Diagnosis of PFD was established retrospectively by manometric plus defecographic findings according to Rome II criteria. Two groups of patients were identified: FC without PFD (FC group) an…
Treatment of injuries to the inferior alveolar nerve after endodontic procedures.
1998
Overextension of filling material into the mandibular canal after root treatment in the lower jaw is a rare but serious complication. Mechanical compression, chemical neurotoxicity and local infection may cause irreversible nerve damage. A report on 11 patients with neurological complaints of the inferior alveolar nerve after endodontic treatment is summarised. The neurological findings are dominated by hypaesthesia and dysaesthesia. Half of the patients reported pain. Hyperaesthesia is found much more rarely. Nearly all the patients had a combination of one or more symptoms. Initial X-rays showed root filling material in the area of the mandibular canal. Nine cases were treated with apicec…
The supracondylar approach to the jugular tubercle and hypoglossal canal.
1998
BACKGROUND Circumscribed lesions of the hypoglossal canal and of the jugular tubercle still remain a surgical challenge. So far, transpetrosal, transcondylar suboccipital, and extreme lateral approaches have been used to access this region. These surgical procedures bear a high risk for neurological deficits. Therefore, we introduce a new minimally invasive extradural approach to the hypoglossal canal that also allows access to the lateral aspects of the jugular tubercle. METHODS After a paramedian retromastoid skin incision, a basal suboccipital craniectomy lateral to the foramen magnum toward the jugular tubercle is performed. With this approach the occipital condyle and the lateral osseo…
Diagnostic performance of reformatted isotropic thin-section helical CT images in the detection of superior semicircular canal dehiscence
2017
Purpose The purpose of this article is to assess the diagnostic performance of computed tomography (CT) reformatted images for detection of superior semicircular canal (SSC) dehiscence. Material and methods Forty-two patients, with sound- and/or pressure-induced vestibular symptoms, and 42 control participants underwent helical CT examination with a highly collimated beam (0.5 mm). Reformatted images of the vestibular labyrinth were obtained in the standard axial and coronal planes (group A images), and in a plane parallel and perpendicular to the SSC (group B images). Diagnostic performance obtained by evaluating the group A images alone and the group B images alone was analyzed by using t…
Influence of loperamide and loperamide oxide on the anal sphincter
1992
The objective of this study was to investigate the effects of the opioid loperamide and its recently synthesized pharmacologically inactive prodrug loperamide oxide on the anal sphincter. In a double-blind, placebo-controlled crossover study, anorectal manometry was performed in 12 healthy volunteers five hours after oral bolus application of 10 mg of loperamide, loperamide oxide, or placebo. Loperamide significantly increased the threshold volumes for minimal perception and urgency to defecate (P less than 0.05) and raised the volume required to abolish recovery of the rectoanal inhibitory reflex (P less than 0.05). These findings suggest that loperamide has a specific continence-improving…
Long-term manometric study of anal sphincter function after hemorrhoidectomy
2006
BACKGROUND AND AIM: Data on maximum resting pressure (MRP) and maximum squeeze pressure (MSP) changes after hemorrhoidectomy are not univocal and follow-up of patients undergoing surgery is mostly short-lived. The aim of this study was to prospectively examine during 1-year follow-up the long-term manometric results of MRP, MSP, and ultra slow wave activity (USWA) within a set of patients undergoing Milligan-Morgan hemorrhoidectomy as compared to healthy controls. MATERIALS AND METHODS: Twenty patients with hemorrhoids of third and fourth degree were enrolled and anorectal manometry was performed preoperatively, on the 5th day, and after 1, 6, and 12 months after surgery. RESULTS: On the 5t…
Manometric Evaluation of Internal Anal Sphincter after Fissurectomy and Anoplasty for Chronic Anal Fissure: A Prospective Study
2012
Chronic anal fissure (CAF) is a common painful clinical disease and its pathogenesis remains poorly understood. After failure of pharmacological therapy, that is the first-line treatment, surgical sphincterotomy remains the treatment of choice although it is followed by a high rate of anal incontinence resulting from the sphincter damage; therefore, the research of a sphincter-saving surgical option has become an important goal. The aim of this study was to evaluate the manometric modifications and the incidence of anal incontinence after fissurectomy and anoplasty with advancement skin flap in patients affected by CAF with hypertonia of the internal anal sphincter (IAS). Fifteen patients …
Botulinum toxin vs. topical glyceryl trinitrate ointment for pain control in patients undergoing hemorrhoidectomy: a randomized trial.
2007
PURPOSE: The maximum resting pressure in the anal canal is greatly raised after hemorrhoidectomy. This increase is likely to be the cause of postoperative pain, which is still the most troublesome early problem after hemorrhoidectomy. This study was designed to compare, after hemorrhoidectomy, the effects of intrasphincter injection of botulinum toxin vs. application of glyceryl trinitrate ointment in improving wound heating and reducing postoperative pain at rest or during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 40 days after hemorrhoi…
