Extracorporeal Stimulation of Sacral Nerve Roots for Observation of Pelvic Autonomic Nerve Integrity: Description of a Novel Methodological Setup.

2017

Introduction: Neurophysiologic monitoring can improve autonomic nerve sparing during critical phases of rectal cancer surgery. Objectives: To develop a system for extracorporeal stimulation of sacral nerve roots. Methods: Dedicated software controlled a ten-electrode stimulation array by switching between different electrode configurations and current levels. A built-in impedance and current level measurement assessed the effectiveness of current injection. Intra-anal surface electromyography (sEMG) informed on targeting the sacral nerve roots. All tests were performed on five pig specimens. Results: During switching between electrode configurations, the system delivered 100% of the set cur…

Botulinum toxin in preparation of oral cavity for microsurgical reconstruction.

2010

CONCLUSIONS: Infiltration of botulinum toxin in the major salivary glands allows a temporary reduction of salivation that begins 8 days afterwards and returns to normal within 2 months. The inhibition of salivary secretion, carried out before the oral cavity reconstructive surgery, could allow a reduction of the incidence of oro-cutaneous fistulas and local complications. OBJECTIVES: Saliva stagnation is a risk factor for patients who have to undergo reconstructive microsurgery of the oral cavity, because of fistula formation and local complications in the oral cavity. The authors suggest infiltration of botulinum toxin in the major salivary glands to reduce salivation temporarily during th…

Evaluation of salivary parameters and dental status in adult hemodialysis patients in an indian population.

2018

Background Renal failure is a process that expresses a loss of functional capacity of the nephrons, independently of its etiology. The most widely used technique to combat renal failure is hemodialysis. Renal failure causes various systemic alterations including oral complications such as variations in the flow and composition of the saliva. Caries is a multifactorial disease and impaired stimulated salivary flow rate and buffering capacity are the best-known risk factors. The present study aims to evaluate the salivary pH, buffering capacity and the flow rate of saliva to the DMFT status in adult hemodialysis patients among the Indian population. Material and Methods Twenty healthy individ…

The Tegument Protein pp65 of Human Cytomegalovirus Acts as an Optional Scaffold Protein That Optimizes Protein Uploading into Viral Particles

2014

ABSTRACT The mechanisms that lead to the tegumentation of herpesviral particles are only poorly defined. The phosphoprotein 65 (pp65) is the most abundant constituent of the virion tegument of human cytomegalovirus (HCMV). It is, however, nonessential for virion formation. This seeming discrepancy has not met with a satisfactory explanation regarding the role of pp65 in HCMV particle morphogenesis. Here, we addressed the question of how the overall tegument composition of the HCMV virion depended on pp65 and how the lack of pp65 influenced the packaging of particular tegument proteins. To investigate this, we analyzed the proteomes of pp65-positive (pp65pos) and pp65-negative (pp65neg) viri…

Inguinal Hernia: Defect Obliteration with the 3D Dynamic Regenerative Scaffold Proflor™.

2021

Prosthetic inguinal hernia repair presents significant challenges. Some of these, such as mesh fixation and quality of the biologic response, are still debated among surgeons. For example, there is no strong consensus regarding a specific condition that characterizes the surgical procedure during herniorrhaphy. This issue concerns management of the hernia defect, which in conventional hernia repair with flat meshes remains patent. However, a critical analysis of typical postoperative complications after inguinal hernia repair reveals that some of these adverse events are related to patency of the hernial opening. Postoperative discomfort, pain with specific movements and even hernia recurre…

Role of Cytoreductive surgery in recurrent ovarian cancer

2010

Ovarian cancer is the leading cause of death from gynecologic malignancy in western countries, primarily because over 60% of patients with ovarian cancer will experience disease recurrence. Primary cytoreductive surgery and combination chemotherapy are the cornerstones of the initial treatment for epithelial ovarian cancer. The management of recurrent ovarian cancer is less clear than that of primary disease. The management of recurrent ovarian cancer is largely based on systemic chemotherapy, with surgery being offered only in selected individuals. Despite this, the benefits of surgery has been shown in a meta-analysis by Bristow et al. where the survival is influenced by the completeness …

Laparoscopic surgical management of localized recurrent ovarian cancer: a single-institution experience

2014

Background: Optimally, secondary cytoreduction is acknowledged as a valid option in terms of oncologic outcome for patients with platinum-sensitive recurrent ovarian cancer. In cases of localized relapse, a laparoscopic approach has been attempted at various institutions, but studies on its role for this subset of patients still are limited. This report describes the authors' experience using laparoscopic secondary cytoreduction for patients with localized recurrent ovarian cancer. The results from a retrospective analysis of a prospective case series are reported. Methods: Between October 2011 and May 2013, 29 patients with localized recurrent ovarian cancer were selected for a laparoscopi…

Reencuadramiento administrativo de socios trabajadores de cooperativas: luces y sombras

2022

En los últimos años, se han cuestionado determinados tipos de cooperativas que aprovecharían las ventajas que les ofrece su especial marco normativo para defraudar las expectativas jurídicas y económicas de las personas que trabajan en ellas y del sistema de Seguridad Social. Es probable que los procedimientos administrativos al respecto no se ajusten a las exigencias de la legislación cooperativa y, sobre todo, han generado bastante inseguridad jurídica. En este contexto, este trabajo pretende aportar alguna reflexión de utilidad para la reforma normativa que se encuentra en marcha.
