The Association of Appendectomy, Adhesions, Tubal Pathology, and Female Infertility.
2019
Background and Objectives: The aim of the study was to investigate a potential association between previous childhood appendectomy, tube pathology, and female infertility. Methods: We reviewed patients seeking care at the fertility clinic of our university medical center between 2006 and 2016. The history of previous appendectomy was extracted from hospital documentation and by telephone follow-up. Tubal patency was assessed by diagnostic laparoscopy and chromopertubation. Results: In our study cohort (N = 237), 24.9% (n = 59) had a history of previous appendectomy. Previous appendectomy, therefore, was about 3-fold more prevalent in women seeking fertility treatment than in the general pop…
Videolaparoscopic cholecystectomy in patients with previous abdominal surgery. Personal experience and literature review
2017
Objectives. Laparoscopic cholecystectomy (LC) is today the "gold standard" treatment of gallbladder stones. Role of LC is still debated in the presence of abdominal scars due to the frequent post-operative adhesions which make access to the peritoneal cavity difficult. This study aim to assess role and outcomes of LC on a previous abdominal surgery on the scarred abdomen. Materials and Methods. we have carried out a retrospective study on 499 consecutive patients who had undergone LC from 2009 to 2015; 21 of these (4.2%) undergone previous abdominal surgery. In all 21 cases the pneumoperitoneum was established with Veress needle at the Palmer's point and the procedure was carried out after …
Adhesive Small Bowel Obstruction: Predictive Factors of Lack of Response in Conservative Management with Gastrografin
2015
<b><i>Background:</i></b> Gastrografin represents a useful tool in the diagnosis and management of adhesive small bowel obstruction (ASBO). The aim of this study is to identify variables with negative influence in nonoperative management with gastrografin. <b><i>Methods:</i></b> From August 2008 to March 2013, 223 consecutive patients with 235 episodes of ASBO were included and received gastrografin. A protocol for prospective data collection was developed. In order to explore factors related to the failure of nonoperative treatment, univariate and multivariate analysis were performed. <b><i>Results:</i></b> One hundred…
Evidence of neurotrophic events due to peritoneal endometriotic lesions
2012
To investigate the neurotrophic properties of endometriosis, as well as the involvement of neurotrophic factors in the development of chronic pelvic pain in patients with endometriosis, we performed a prospective clinical study. The presence of neurotrophins was investigated in the peritoneal fluid (PF) of patients with peritoneal endometriotic lesions or adenomyosis, as well as from women with non-endometriotic adhesions and from women without endometriosis/adenomyosis/adhesions. The PF from patients with peritoneal endometriotic lesions was divided in three groups: asymptomatic endometriosis, minimal pain and severe pain. PF from patients with adenomyosis or with non-endometriotic adhesio…
A pilot study of laparoscopic adhesion prophylaxis after myomectomy with a copolymer designed for endoscopic application.
2009
Abstract Study Objective To assess the laparoscopic handling and safety of D,L-polylactide-e-caprolactone-trimethylene carbonate (PCT) copolymer after myomectomy and compare it with icodextrin. In contrast to previously developed solid barriers, the material has rationally designed properties that are advantageous for convenient laparoscopic application. Design A randomized, single-blinded clinical study (Canadian Task Force Classification I). Setting Single-center study in a German University Hospital. Patients Thirty patients who underwent laparoscopic myomectomy were enrolled. Interventions After laparoscopic myomectomy and subsequent reconstruction of the uterus with interrupted sutures…
Effects of femtosecond laser and other surface treatments on the bond strength of metallic and ceramic orthodontic brackets to zirconia.
2017
Femtosecond laser has been proposed as a method for conditioning zirconia surfaces to boost bond strength. However, metallic or ceramic bracket bonding to femtosecond lasertreated zirconia surfaces has not been tested. This study compared the effects of four conditioning techniques, including femtosecond laser irradiation, on shear bond strength (SBS) of metallic and ceramic brackets to zirconia.Three hundred zirconia plates were divided into five groups: 1) control (C); 2) sandblasting (APA); 3) silica coating and silane (SC); 4) femtosecond laser (FS); 5) sandblasting followed by femtosecond laser (APA+SC). A thermal imaging camera measured temperature changes in the zirconia during irrad…
Role of Ovarian Suspension in Preventing Postsurgical Ovarian Adhesions in Patients with Stage III-IV Pelvic Endometriosis: A Systematic Review.
2018
Endometriosis is a benign complex gynecological condition with high morbidity that affects women of reproductive age. Pelvic adhesion formation represents a serious clinical challenge in the management of patients with endometriosis. Several interventions have been proposed over the last few years aiming to reduce post-operative ovarian adhesions formation. The aim of this study is to summarize the evidence of the efficacy of ovarian suspension in the prevention of post-operative ovarian adhesions formation in women undergoing laparoscopic surgery for stage III-IV endometriosis. The research was conducted using electronic databases. A review of the abstracts of all references retrieved from…
DNA nanofilm thickness measurement on microarray in air and in liquid using an atomic force microscope.
2005
International audience; The measurement of the thickness of DNA films on microarray as a function of the medium (liquid, air) is gaining importance for understanding the signal response of biosensors. Thiol group has been used to attach DNA strands to gold micropads deposited on silicon surface. Atomic force microscopy (AFM) was employed in its height mode to measure the change in the pad thickness and in its force mode to measure the indentation depth of the nanofilm. A good coherence between the height and force modes is observed for the film thickness in air. The adhesion force was found to be an alternative way to measure the surface coverage of the biolayer at nanoscopic scale. However…
Magnetic resonance imaging of dysraphic myelodysplasia
1988
The spinal cord in 56 children and adolescents was examined by magnetic resonance imaging (MRI) many years after neonatal surgery on a meningomyelocele (average age 12 years). In a high percentage of cases, the diagnosis "tethered cord" was made. Associated anomalies were found with a frequency of 21%. Typical findings are presented and the impact of these results on therapy planning is discussed.
ANATOMICAL AND FUNCTIONAL OUTCOMES OF SYMPTOMATIC IDIOPATHIC VITREOMACULAR TRACTION
2016
To describe the natural history of eyes with symptomatic idiopathic vitreomacular traction (VMT).Retrospective multicenter study of 168 eyes with spectral-domain optical coherence tomography (SD-OCT) findings consistent with idiopathic VMT. All eyes were graded according to SD-OCT findings. Grade 1 was defined as incomplete cortical vitreous separation with foveal attachment. Grade 2 was defined as Grade 1 plus intraretinal cysts or clefts. Grade 3 was defined as Grade 2 plus a foveal detachment. All patients were followed for at least 6 months.There were 168 patients (51 men) with a mean age of 68.8 ± 10.7 years. Patients were followed for a mean of 22.7 ± 20.1 months. The mean duration of…
