Enfermedad del hígado graso no alcohólico, asociación con la enfermedad cardiovascular y tratamiento ( I ). Enfermedad del hígado graso no alcohólico…
2017
Non-alcoholic fatty liver disease (NAFLD) comprises a series of histologically lesions similar to those induced by alcohol consumption in people with very little or no liver damage. The importance of NAFLD is its high prevalence in the Western world and, from the point of view of the liver, in its gradual progression from steatosis to steatohepatitis, cirrhosis, and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with acceleration of arteriosclerosis and events related to it, being the main cause of its morbidity and mortality. This review, updated to January 2016, consists of two parts, with the first part analysing the associa…
NeXt for neuro-radiosurgery: A fully automatic approach for necrosis extraction in brain tumor MRI using an unsupervised machine learning technique
2017
Stereotactic neuro-radiosurgery is a well-established therapy for intracranial diseases, especially brain metastases and highly invasive cancers that are difficult to treat with conventional surgery or radiotherapy. Nowadays, magnetic resonance imaging (MRI) is the most used modality in radiation therapy for soft-tissue anatomical districts, allowing for an accurate gross tumor volume (GTV) segmentation. Investigating also necrotic material within the whole tumor has significant clinical value in treatment planning and cancer progression assessment. These pathological necrotic regions are generally characterized by hypoxia, which is implicated in several aspects of tumor development and gro…
Overexpression of nerve growth factor in peritoneal fluid from women with endometriosis may promote neurite outgrowth in endometriotic lesions
2011
To investigate the role of the nerve growth factor (NGF) in the endometriosis-associated innervation in the development of endometriosis- associated symptoms, 41 peritoneal fluid samples (PF) from patients with surgically and histologically proven endometriosis and 20 PF from patients with other gynecologic conditions were analyzed with Western blot and a novel in vitro model using dorsal root ganglia (DRG) to show neuronal outgrowth; endometrial cells also were analyzed. The results suggest that the PF of endometriosis patients and endometriotic lesions have neurotropic properties, because the Western blot analysis and the cell culture stainings showed NGF expression, and the neurite outgr…
Ticlopidine in the Treatment of Multiple Atherosclerotic Arteriopathy: a Strain Gauge Plethysmography and Döppler Spectrum Analysis Evaluation
1987
The effect of ticlopidine was compared with flunarizine in patients with iliac–femoral and / or femoral–popliteal arteriosclerotic arteriopathy accompanied by lesions of the cervical arteries of no haemodynamic significance. In the lower limbs, plethysmography (strain gauge measurements) and Döppler ultrasonography integrated by spectral analysis of the cervical arteries showed qualitative and quantitative improvements of the regional haematic flow. Side-effects were negligible which suggests that ticlopidine is useful in the treatment of multiple arteriosclerotic arteriopathy.
Risk Factors, Lifestyle and Prevention among Adolescents with Idiopathic Juvenile Scoliosis: A Cross Sectional Study in Eleven First-Grade Secondary …
2021
Adolescent idiopathic scoliosis (AIS) has an incidence of 2–3% in the general population and a multifactorial etiology. The present study aims to analyze modifiable risk factors and their interactions in the development of AIS in order to increase knowledge about the disease and to prevent the evolution of AIS in young students with tailored public health strategies. A cross-sectional study was conducted over two consecutive school years among students attending 11 first-grade secondary schools in the province of Palermo, Italy. A self-administered questionnaire that investigated socio-demographical, physical and anamnestic characteristics and habits, focusing on possible risk factors…
Laparoscopic neurolysis of the sacral plexus and the sciatic nerve for extensive endometriosis of the pelvic wall
2007
Background: The aim of this study is to report on the feasibility of laparoscopic neurolysis of the plexus sacralis and the sciatic nerve in deep endometriotic infiltration of the lateral pelvic wall. Methods: A transperitoneal approach to the pelvic nerves combined with the LANN technique for intraoperative assessment of the function of the exposed nerves permit exposure and sparing of all somatic nerves during resection of the endometriotic lesion. Results: We report on our short experience with 21 patients who underwent this technique for the treatment of endometriotic infiltration of the sacral plexus at different levels. Conclusion: In young patients with chronic unilateral sciatica or…
Einwachsverhalten von periostgedeckten Knochendübeln mit und ohne autologe Knorpelzellen
2003
Autologous osteochondral transplantation has the major disadvantage of significant damage to a healthy joint surface at the donor site. The purpose of this study was to examine the effect of autogenous chondrocytes injected into the periosteum of autologous bone grafts in order to provide an alternative method for cartilage repair. A total of 22 Gottinger minipigs were operated twice on both knees. The first operation served for cartilage biopsy for the chondrocyte culture. During the second operation an osteochondral defect was created in the medial facet of the trochlear groove. The defect was treated differently with an autologous cortico-cancellous bone cylinder,harvested from the proxi…
AORTIC STIFFNESS IS INCREASED IN NORMOTENSIVE PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS
2018
INTRODUCTION: Patients with systemic lupus erythematosus (SLE) have a 4- to 10-fold increased risk of developing cardiovascular (CV) events compared with the general population. The enhanced CV risk conferred by SLE may in part be mediated through preclinical CV damage. Large artery stiffness is usually assessed by measuring aortic pulse wave velocity (aPWV), a marker of early vascular aging (EVA) and an independent predictor of adverse CV prognosis. Several studies examined aortic stiffness in SLE with inconsistent results. AIM: To evaluate aPWV and the prevalence of EVA in a group of normotensive patients with SLE and to compare these values with those obtained in age- and gender- matched…
Minimal invasive posterior correction of Lenke 5C idiopathic scoliosis: comparative analysis of minimal invasive vs. open surgery
2019
Introduction Surgical management of adolescent idiopathic scoliosis in spite of usually favourable outcomes is still a major operation. Therefore, efforts are being undertaken to minimalize the procedure, reduce the surgical trauma and postoperative convalescence. The study was designed to compare posterior minimal invasive surgery using navigation based on intraoperative 3D imaging and standard open instrumented fusion in Lenke 5C idiopathic scoliosis treatment. Materials and methods From eight patients with Lenke 5C curves planned for posterior correction and instrumented fusion, four were treated with minimally invasive and four had open procedure. Operation length, estimated blood loss,…
Value of serial magnetic resonance imaging in the assessment of brain metastases volume control during stereotactic radiosurgery
2016
AIM To evaluate brain metastases volume control capabilities of stereotactic radiosurgery (SRS) through serial magnetic resonance (MR) imaging follow-up. METHODS MR examinations of 54 brain metastases in 31 patients before and after SRS were reviewed. Patients were included in this study if they had a pre-treatment MR examination and serial follow-up MR examinations at 6 wk, 9 wk, 12 wk, and 12 mo after SRS. The metastasis volume change was categorized at each follow-up as increased (> 20% of the initial volume), stable (± 20% of the initial volume) or decreased (< 20% of the initial volume). RESULTS A local tumor control with a significant (P < 0.05) volume decrease was observed in 25 meta…
