Current role of computed tomography-guided transthoracic needle biopsy of metastatic lung lesions.
2015
ABSTRACT Aim: As part of the Catania symposium on lung metastasectomy we reviewed our practice of computed tomography (CT)-guided percutaneous transthoracic needle biopsy of pulmonary metastatic lesions with particular emphasis on diagnostic accuracy and nature of complications lesions. Materials & methods: 25 patients with metastatic lesions of the lung have been evaluated between May 2010 and February 2014. Inclusion criteria consisted of patients with histologically confirmed, metastatic disease of the lung, those receiving a CT-guided needle biopsy, were at least 18 years of age; and with adequate hepatic, renal and hematological function. We recorded also the size of the sampled …
Added Value of Multiparametric Magnetic Resonance Imaging to Clinical Nomograms for Predicting Adverse Pathology in Prostate Cancer
2018
PURPOSE: We examined the additional value of preoperative prostate multiparametric magnetic resonance imaging and transrectal ultrasound/multiparametric magnetic resonance imaging fusion guided targeted biopsy when performed in combination with clinical nomograms to predict adverse pathology at radical prostatectomy. MATERIALS AND METHODS: We identified all patients who underwent 3 Tesla multiparametric magnetic resonance imaging prior to fusion biopsy and radical prostatectomy. The Partin and the MSKCC (Memorial Sloan Kettering Cancer Center) preradical prostatectomy nomograms were applied to estimate the probability of organ confined disease, extraprostatic extension, seminal vesicle inva…
A case report of pulmonary vein isolation performed in a patient with polysplenia and interrupted inferior vena cava
2021
Abstract Background Pulmonary vein isolation (PVI) has entrenched itself as one of the main approaches for the treatment of paroxysmal symptomatic atrial fibrillation (AF). Pulmonary vein isolation prevents focal triggers from pulmonary veins from initiating AF paroxysms. As standard—PVI is performed through the inferior vena cava (IVC) approach, through the femoral vein. However, there are conditions when this approach is not appropriate or is not available. Case summary We report a case of a 53-year-old male who was referred to Pauls Stradins Clinical University Hospital for PVI due to worsening AF. Due to the rare anatomical variant of the venous system, the standard approach to PVI coul…
Efficacy of the NaviTip FX irrigation needle in removing calcium hydroxide from root canal
2012
Objective: To evaluate the effectiveness of the NaviTip FX, brush-covered irrigation needle, in removing calcium hydroxide from the root canal. Study Design: Thirty single-rooted teeth were randomly divided into three groups: A - irrigation with a hypodermic needle inserted as far as possible without binding and activation with #30 K-type file; B - Irrigation with a hypodermic needle without activation; C - irrigation with NaviTip FX needle. Sodium hypoclorite 1% was used in irrigation. The root canals were examined trough scanning electron microscopy. Calcium hydroxide removal was recorded at 1, 5, and 10mm from the working length (WL) and the data were analysed using one-way ANOVA test (p…
The “Jacobsen Flap” Technique: A Safe, Simple Surgical Procedure to Treat Dupuytren Disease of the Little Finger in Advanced Stage
2010
The "Jacobsen flap" technique: a safe, simple surgical procedure to treat Dupuytren disease of the little finger in advanced stage. Tripoli M, Cordova A, Moschella F. Source Chirurgia Plastica e Ricostruttiva, Dipartimento di Discipline Chirurgiche ed Oncologiche, Università degli Studi di Palermo, Italy. matripoli@yahoo.it Abstract The surgery for advanced stages of Dupuytren disease of the little finger is controversial. In the literature, several techniques have been described with variable reported results and postoperative complications. Percutaneous needle fasciotomy, McCash technique, and dermofasciectomy are often performed for surgical treatment but they present significant complic…
Imiquimod-Induced Psoriasis in Mice Depends on the IL-17 Signaling of Keratinocytes
2018
The pathology of psoriasis strongly depends on IL-17A. Monoclonal antibodies blocking either the cytokine or its receptor are among the most efficient treatments for psoriatic patients. Keratinocytes can be activated upon exposure to IL-17A and tumor necrosis factor-α and secrete secondary cytokines and chemokines in the inflamed skin. In psoriasis and its imiquimod-induced mouse model, a strong skin infiltration of neutrophils and inflammatory monocytes can be observed. However, to date, it is not clear how exactly those cellular populations are attracted to the skin and how they contribute to the pathogenesis of the disease. To define the crucial cell type responding to IL-17 and initiati…
Improved noninvasive prediction of liver fibrosis by liver stiffness measurement in patients with nonalcoholic fatty liver disease accounting for con…
2016
Background and aims: Liver stiffness measurement (LSM) frequently overestimates the severity of liver fibrosis In Nonalcoholic Fatty Liver Disease (NAFLD). Controlled Attenuation Parameter (CAP) is a new parameter provided by the same machine used for LSM, and associated with both steatosis and BMI, the two factors mostly affecting LSM peformance in NAFLD. We aimed to determine wheter prediction of liver fibrosis by LSM in NAFLD patients is affected by CAP values. Methods: Patients (n=324) were assessed by clinical and histological (Kleiner score) features. LSM and CAP were performed using the M probe. CAP values were grouped by tertiles (lower from 132 to 298, middle from 299 to 338, highe…
Deep dry needling of trigger points located in the lateral pterygoid muscle: efficacy and safety of treatment for management of myofascial pain and t…
2014
Background To determine whether deep dry needling (DDN) of trigger points (TPs) in the lateral pterygoid muscle (LPM) would significantly reduce pain and improve function, compared with methocarbamol/paracetamol medication. Material and Methods Forty-eight patients with chronic myofascial pain located in the LPM were selected and randomly assigned to one of two groups (DDN test group, n=24; drug-treated control group, n=24). The test group received three applications of needling of the LPM once per week for three weeks, while control group patients were given two tablets of a methocarbamol/paracetamol combination every six hours for three weeks. Assessments were carried out pretreatment, 2 …
Antioxidant potential of Himanthalia elongata for protection against ischemia-reperfusion injury in the small bowel
2016
Seaweed has been associated with the prevention and/or treatment of various diseases related to oxidative stress because of its antioxidant activity. We investigated the protective potential of extract of Himanthalia elongata against ischemia-reperfusion (I/R) injury in the intestine of rats.Seventy-two (72) male Wistar albino rats were randomly assigned into 12 groups as follows: sham, I/R only, I/R plus vehicle at 3 time points, and I/R plus extract at 3 time points. The degree of intestinal injury was determined by oxidative stress using lipid peroxidation, superoxide dismutase, catalase, and glutathione peroxidase after mesenteric ischemia-reperfusion. A histological study was also perf…
Endoscopic cytology in biliary strictures. Personal experience
2008
The differential diagnosis between malignant and benign biliary strictures is the cornerstone of the management of jaundiced patients. The aim of our study is to define the role of cytology of the bile withdrawn during endoscopic retrograde cholangiopancreatography (ERCP), to reach a diagnosis of the nature of biliary stricture.This retrospective study was conducted on 67 consecutive patients affected of ingravescent obstructive jaundice who underwent ERCP+/-PTE (percutaneous transhepatic endoscopic)+bile withdrawn+stenting. We founded hilar stricture in 21 patients (31.3%), middle third the common duct stricture in 17 (25.3%), and lower third stricture in 28 patients (41.4%). In one patien…
