Factors that influence exhaled nitric oxide in Italian schoolchildren

2008

Conflicting results exist about the meaning of exhaled nitric oxide (eNO) in epidemiologic studies, mainly because of the numerous factors that may affect the measurement.To evaluate the role of the factors that influence eNO levels in a sample of schoolchildren with or without respiratory diseases. We studied 335 schoolchildren, ages 10 to 16 years, from 8 schools in Palermo, Italy. After a respiratory questionnaire was completed, spirometry, skin tests, and eNO measurements were performed.Among 335 children, 13.7% reported symptoms of bronchial asthma, 46.9% reported symptoms of rhinitis, and 39.4% were asymptomatic. The ratio of forced expiratory volume in 1 second to forced vital capaci…

Discovery of an epidermoid of the skull concomitant with a homolateral subacute traumatic subdural hematoma

1979

The case of a man of 32 years with an epidermoid of the left side of the skull is reported. The tumor itself was asymptomatic and was discovered accidentally because of a subdural hematoma on the same side. After a closed head injury, this patient had symptoms of an intracranial space occupying lesion (hematoma) on the left after a symptom-free interval. The left carotid angiogram demonstrated the characteristic picture of a subdural hematoma in the left parieto-temporo-occipital region. At the same time, characteristic changes in the skull on the same side, which were more apparent after removal of the hematoma, suggested an epidermal tumour of the skull. This was verified at operation.

Subclinical executive function impairment in children with asymptomatic, treated phenylketonuria: A comparison with children with immunodeficiency vi…

2018

In this study we compared the neuropsychological profile of phenylketonuria (PKU) and human immunodeficiency virus (HIV) to examine the specificity of the executive function (EF) impairment reported in these two patologies. A total of 55 age-matched children and adolescents were assessed, including 11 patients with PKU, 16 patients with HIV and 28 healthy controls, underwent a neuropsychological assessment. Although neither the PKU nor the HIV group scored below the normative ranges, both groups showed lower scores in neuropsychological tests engaging EFs than controls. In addition, compared to patients with PKU the HIV group performed significantly worse in the Trail-Making Test A, Corsi S…

Vascular leiomyoma in the oral cavity : report of two cases

2019

Vascular leiomyomas (VL) are benign lesions of perivascular origin. We report two new cases and discuss their clinical, histological and immunohistochemical characteristics, in order to facilitate the diagnosis and treatment of such lesions. The patients, both male, presented asymptomatic nodules located in the bottom of the labial sulcus and buccal mucosa. In the second case, color doppler ultrasonography was performed, which showed no change in blood flow. After excisional biopsies, a limited lesion was observed histologically, with multiple tortuous vessels of varying sizes and calibers, and among them, spindle cells bundles, positive for smooth muscle actin. Oral VLs have clinical featu…

Do genetic polymorphisms in angiotensin converting enzyme 2 (ACE2) gene play a role in coronavirus disease 2019 (COVID-19)?

2020

Abstract Although some demographic, clinical and environmental factors have been associated with a higher risk of developing coronavirus disease 2019 (COVID-19) and progressing towards severe disease, altogether these variables do not completely account for the different clinical presentations observed in patients with comparable baseline risk, whereby some subjects may remain totally asymptomatic, whilst others develop a very aggressive illness. Some predisposing genetic backgrounds can hence potentially explain the broad inter-individual variation of disease susceptibility and/or severity. It has been now clearly established that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2…

Renal function and carotid atherosclerosis in adults with no known kidney disease

2017

Abstract Background and aims A high prevalence of atherosclerotic lesions characterizes patients with chronic kidney disease, though there is little data on the relationship between kidney function and atherosclerotic changes in the healthy population or in people with no known renal impairment. The aim of our study was to analyze, in a comprehensive general population with no known kidney disease, the relationship between renal function and subclinical carotid atherosclerotic damage. Methods and results A general real-life population of 611 participants (233 males and 378 females; age ≥18 years) with no known kidney failure was selected for the study. The glomerular filtration rate (GFR) w…

Aneurysma des Ductus arteriosus Botalli

2000

A congenital aneurysm of the ductus arteriosus Botalli was detected by chest X-ray as an intrathoracic mass in a 7-day-old infant. Following confirmation of the diagnosis by echocardiography and MRI the aneurysm was successfully resected via left lateral thoracotomy without cardiopulmonary bypass. The postoperative course was uneventful. Six years after operation the patient is asymptomatic and growing normally. An intrathoracic mass may be considered in the differential diagnosis especially in infants and children. Aneurysms of ductus arteriosus potentially are associated with serious complications. Timely diagnosis and early surgical intervention are decisive for prevention of serious com…

Feasible Evaluation of PQ Bypass Results with Duplex Ultrasound

2019

Abstract Patients with peripheral arterial disease (PAD) have substantially impaired health-related quality of life (HR-QoL). Chronic lower limb ischaemia due to the atherosclerotic occlusion of infra-inguinal arteries is one of the most important causes of invalidity among smokers over the age of fifty. Historically, these lesions were treated by open bypass surgery. Less invasive endovascular revascularisation methods are available to treat short lesions, while treatment of long lesions are lacking. Fully endovascular trans-venous femoro-popliteal bypass (PQ Bypass, Inc., Sunnyvale, CA, USA) to treat long femoral lesions has been developed recently. The objective of the study was to evalu…

Assessment of human cytomegalovirus specific T cell immunity in human immunodeficiency virus infected patients in different disease stages following …

2004

T cell immunity to human cytomegalovirus (HCMV) was assessed in HAART-treated HIV-1 infected patients (9 asymptomatic, CDC group A; and 22 symptomatic, CDC group B), and in eight HIV-1 long term non-progressors. Patients were either prospectively or cross-sectionally examined for CD4(+) T cell counts, HIV RNA load, HCMV leukoDNAemia, HCMV DNA in urine, lymphoproliferative response (LPR) to HCMV and phytohemagglutinin (PHA), and cytokine secretion (IFN-gamma and IL-4) by HCMV-stimulated peripheral blood mononuclear cell (PBMC) cultures. No patient either progressed to clinical AIDS or developed HCMV active infection during the study period. Twenty-nine patients responded to HAART, though 12 …

Management of Atrial Fibrillation Suppression in AF-HF Comorbidity Therapy (MASCOT) Trial

2003

Inter- [1,2], intra- [3,4], and atrioventricular [51(AV) dyssynchrony are not new concepts, but only recently have attempts been made to correct these disorders in an effort to treat heart failure (HF). A series of trials [6] has addressed partial or comprehensive cardiac resynchronization in patients with severe HF and evidence of cardiac dyssynchrony. Cardiac resynchronization should improve left ventricular (LV) performance; several trials [7-10] have demonstrated improvement in many hemodynamic parameters (LV and aortic pressure, shortening of mitral diastolic regurgitation, synchronized LV and atrial systole, LV volume, reduced myocardial oxygen consumption) and clinical end-points (qu…
