Pulmonary artery sarcoma with angiosarcoma phenotype mimicking pleomorphic malignant fibrous histiocytoma: a case report
2012
Abstract Primary sarcomas of the major blood vessels can be classified based on location in relationship to the wall or by histologic type. Angiosarcomas are malignant neoplasms that arise from the endothelial lining of the blood vessels; those arising in the intimal compartment of pulmonary artery are rare. We report a case of pulmonary artery angiosarcoma in a 36-year old female with pulmonary masses. The patient had no other primary malignant neoplasm, thus excluding a metastatic lesion. Gross examination revealed a thickened right pulmonary artery and a necrotic and hemorrhagic tumor, filling and occluding the vascular lumen. The mass extended distally, within the pulmonary vasculature …
The prevalence of eating disorders in adolescents with idiopathic scoliosis
2008
This study examines the hypothesis of an association between adolescent idiopathic scoliosis (AIS) and eating disorders (EDs). A population of young females affected by AIS has been interviewed for a possible diagnosis of EDs. The proportion of individuals with EDs resulted significantly larger than normative epidemiological data: Prevalences were 9.2% for anorexia nervosa (AN), 7.7% for bulimia nervosa (BN) and 5.3% for eating disorders not otherwise specified (EDNOS). The relationship between EDs and AIS was further tested through a second analysis. Severity of the rachides pathology was correlated with the presence of AN. Our study supports the hypothesis of a comorbidity between AIS and…
Preterm birth: seven-year retrospective study in a single centre population
2019
Preterm birth is a health and social problem, considered the leading cause of neonatal mortality worldwide. It is associated with higher rates of neurodevelopmental morbidity, sensorineural impairments and other complications. The aim of the study was to describe the incidence and the major risk factors associated with preterm birth. METHODS: We performed a single center, observational and retrospective Cohort study in the Division of Obstetrics and Gynaecology, University Hospital "G. Martino", Messina. Clinical records of all pregnant women who delivered from 1st January 2010 to 31 of December 2016 were collected. RESULTS: In the 7 years considered, a total of 7954 pregnant women were inc…
Elevated Protein Content and Prolyl 4-Hydroxylase Activity in Severely Degenerated Human Annulus Fibrosus
2000
Alterations involved with the intervertebral disc degeneration are partly well described, however, it is not so well known how collagen network is affected by the disease. We analyzed the rate of collagen biosynthesis (estimated by the enzymic activities of prolyl 4-hydroxylase and galactosylhydroxylysyl glucosyltransferase) and the level of hydroxylysylpyridinoline and lysylpyridinoline crosslinks both in normal (n=7) and degenerated (n=7) human annulus fibrosus. The activity of prolyl 4-hydroxylase was significantly increased in degenerated tissue. However, no significant changes in the collagen content or in the amount of hydroxylysylpyridinoline and lysylpyridinoline collagen crosslinks…
Acute Respiratory Distress Syndrome Caused by Pulmonary Nocardiosis in a Patient With Systemic Lupus Erythematosus
2005
Nocardia is a gram-positive bacillus that infects mainly immunodepressed patients. Its association with lupus erythematosus has been described only occasionally and we have found no reports in the literature of an association between lupus and acute respiratory distress syndrome due to pulmonary nocardiosis. We present such a case and discuss the mechanisms that make this lung infection so virulent as well as its epidemiological and microbiological characteristics, clinical presentation, diagnosis, and treatment.
Circulating miR-200–family micro-RNAs have altered plasma levels in patients with endometriosis and vary with blood collection time
2015
Objective To determine whether circulating micro-RNA (miR) 200a, miR-200b, and miR-141 have altered levels in patients with endometriosis compared with control individuals. Design Experimental laboratory study. Setting University. Patient(s) Patients with endometriosis (n = 61), laparoscopically confirmed endometriosis-free women (n = 35), and self-reported healthy women (n = 30) were included in the study. Intervention(s) None. Main Outcome Measure(s) Plasma miRNA levels in endometriosis patients and control subjects. Result(s) We found that the levels of studied miRNAs varied with blood collection time, being lower in the morning than in the evening. When blood collection time was taken i…
Equivalence of the 3-month and 28-day formulations of triptorelin with regard to achievement and maintenance of medical castration in women with endo…
2003
OBJECTIVE: The present study aims at demonstrating the equivalence of the 28-day and 3-month formulations of triptorelin SR (sustained release) in terms of percentage of patients achieving castration levels of estradiol (<==50 pg/mL) 84 days after treatment initiation. DESIGN: A phase II, prospective, randomized, multicenter, open study was conducted in two parallel groups of women with endometriosis. SETTING: Academic hospitals. PATIENT(S): Seventy-two women with endometriosis. were treated with a single intramuscular injection of 3-month triptorelin SR, and 74 patients were treated with one intramuscular injection of 28-day triptorelin SR every 28 days for 3 months. INTERVENTION(S): As pa…
Clinical relevance of objectifying colposcopy.
2014
Purpose: To evaluate the clinical value of four objective colposcopic criteria inner border, ridge sign, cuffed crypt openings and rag sign to diagnose cervical intraepithelial neoplasia grade 2 or worse (CIN 2+), using video exoscopy and to compare it to subjective graduating signs. Methods: Retrospective evaluation of video recordings of 444 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and if indicated loop excisions. Most severe histological diagnosis was recorded. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and likelihood ratios (LR) with 95 % confidence interval, for CIN 2+ were calculated. Results: Singl…
Feasibility and safety of two different surgical routes for the eradication of recto-vaginal endometriosis with vaginal mucosa infiltration (Endo-Vag…
2020
Introduction: Recto-vaginal endometriosis surgical management needing partial colpectomy is a surgically challenging condition and has been associated with a notable risk of major postoperative complications. In the present study we sought to compare feasibility and safety of total laparoscopic (TL) and vaginal-assisted (VA) routes in women affected by symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration scheduled for minimally invasive surgery. Material and methods: Multi-centric, retrospective cohort study on medical records of consecutive reproductive age women submitted to complete macroscopic eradication of symptomatic recto-vaginal endometriosis with vaginal mucosa…
Aortic root dilation in associated with the reduction in capillary density observed at nailfold capillaroscopy in SSc patients
2020
Systemic sclerosis (SSc) is an autoimmune disease characterized by endothelial dysfunction and fibroblasts activation. Microvascular disease may be easily observed by means of nailfold capillaroscopy. Recent evidences emphasized also the involvement of large-medium arteries in SSc, mainly in terms of increased stiffness of the vessel wall. The study aims to measure aortic root diameter in a cohort of SSc patients and to correlate echocardiographic findings with the capillaroscopic pictures. We analyzed the clinical records of 125 consecutive SSc patients (M/F 14/111, mean age 55 ± 12.7 years, median disease duration 11 years) referring in 3 second-level rheumatology centers. All subjects un…
