The objective of this cross-sectional and retrospective cohort study was (1) to determine the usefulness of intima-media thickness (IMT) in contrast to plaque assessment, (2) to examine the value of additive femoral artery sonography and (3) to identify potential risk factors for atherosclerosis and incident cardiovascular events in systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) patients. In this study, 90 SSc and 100 SLE patients were examined by duplexsonography. IMT was measured in common carotid and common femoral arteries, plaques were assessed in common, internal and external carotid and common, proximal superficial and deep femoral arteries.

Oral squamous cell carcinoma among Yemenis: Onset in young age and presentation at advanced stage

2012

Objectives: Oral cancer represents a health burden worldwide. Up to 90% of oral cancer cases are squamous cell carcinomas (SCC). The data on oral SCC in Yemen are lacking. The objective of this study therefore was to describe and analyze the demographic, clinical and histological characteristics of Yemeni patients with oral SCC. Study Design: In this cross-sectional study, two sets of retrospective data for Yemeni cancer patients were obtained officially by two different registries. Patients with oral SCC were included. Their ages were dichotomized using 40 and 45 years alternately as individual cut-points for young and old patients. The patients` demographic, clinical and histological char…

Occurrence of Contralateral Lymph Neck Node Metastasis in Patients with Squamous Cell Carcinoma of the Oral Cavity

2014

Introduction: Squamous cell carcinoma represents about 90% of malignancies of the mouth and about 38% of the head and neck tumors. The behavior of the cancer is very aggressive, presenting early cervical metastasis and, often contralateral ranging from 0.9 to 36%. Objectives: This study aims to analyze clinical and pathological factors that may influence metastasis of squamous cell carcinoma in cervical lymph nodes and relate this occurrence in the contralateral primary tumor, with disease prognosis and the interference of this type of metastasis in the survival rate of patients with this pathology. Material and Metohds: It was conducted a retrospective study from medical records of patient…

Antisynthetase syndrome (AS) in patients with diffuse interstitial lung disease (ILD)

2015

Objectives: To determine the prevalence of SAS in patients with ILD and its clinical characteristics, evolution and specific manifestations linked to each antisynthetase antibodies and highlight the need for its screening in ILD. Methods: Retrospective analysis of patients registered in the last two years in our ILD unit, determining antisynthetase antibodies and analyzing clinical, radiological, functional data and illness evolution. Results: 119 ILD patients were included, 10.9% had antisynthetase antibodies, the most prevalent were Jo-1 (46.1%) and PL-12 (38.5%). In PL-12 patients inicial and respiratory syntoms were predominant, whereas in the Jo-1 patients were more frequent extrapulmo…

Time trends, sociodemographic and health factors associated with discharge and length of stay of hospitalised patients with sickle cell disease in Gh…

2021

ObjectivePatients with sickle cell disease (SCD) are prone to multiple episodes resulting in frequent hospital visits. We determined the time trends, sociodemographic and health factors associated with length of stay (LoS) for patients with SCD in Ghana.Design, participants, settingWe retrospectively analysed SCD hospitalisation records of 22 680 patients from a nationwide database of the Ghana Health Service from 2012 to 2017.Outcome measuresFactors associated with LoS were estimated using Cox regression, while the cumulative incidence of being discharged alive was estimated with in-hospital death as a competing risk.ResultsPatients admitted for SCD over 6 years constituted 22 680 (0.8%) o…

The paradox of the evidence about invasive fungal infections prevention

2016

Invasive fungal infections (IFIs) are characterized by high morbidity and mortality in non-neutropenic critically ill patients. Attributable mortality due to Candida spp. infections ranges from about 42 to 63 % [1, 2]. Data from large observational and retrospective studies show an association between early antifungal treatment and improved survival [3, 4]. Updated clinical practice guidelines for the management of candidiasis have been recently published [5]. In 2006, Playford et al. published a Cochrane systematic review investigating the use of antifungal agents for prevention of IFIs in non-neutropenic critically ill patients [6]. In that review, the outcome of proven IFI was defined as…

The changing scenario of hepatocellular carcinoma in Italy: an update

2021

Background and aims: Epidemiology of hepatocellular carcinoma (HCC) is changing in most areas of the world. This study aimed at updating the changing scenario of aetiology, clinical presentation, management and prognosis of HCC in Italy during the last 15 years. Methods: Retrospective analysis of the Italian Liver Cancer (ITA.LI.CA) database included 6034 HCC patients managed in 23 centres from 2004 to 2018. Patients were divided into three groups according to the date of cancer diagnosis (2004-2008, 2009-2013 and 2014-2018). Results: The main results were: (i) a progressive patient ageing; (ii) a progressive increase of non-viral cases and, particularly, of ‘metabolic’ and ‘metabolic + alc…

Diagnostic Value of Prenatal MR Imaging in the Detection of Brain Malformations in Fetuses before the 26th Week of Gestational Age.

2016

BACKGROUND AND PURPOSE: In several countries, laws and regulations allow abortion for medical reasons within 24–25 weeks of gestational age. We investigated the diagnostic value of prenatal MR imaging for brain malformations within 25 weeks of gestational age. MATERIALS AND METHODS: We retrospectively included fetuses within 25 weeks of gestational age who had undergone both prenatal and postnatal MR imaging of the brain between 2002 and 2014. Two senior pediatric neuroradiologists evaluated prenatal MR imaging examinations blinded to postnatal MR imaging findings. With postnatal MR imaging used as the reference standard, we calculated the sensitivity, specificity, positive predictive value…

[Adverse reactions to human papillomavirus vaccine in the Valencian Community (2007-2011)].

2014

Introduction: In 2009, two cases of seizures in adolescents following quadrivalent human papillomavirus vaccine (qHPV) administration generated important media attention, and adversely affected public trust in this vaccine. Our objectives were to describe suspected adverse reactions (SARs) reported to the Pharmacovigilance Centre in the Valencian Community (PCVC) after administration of HPV vaccine, and to compare reporting rates of syncope and seizures following this vaccine with those of other vaccines administered to girls aged 13–15 years. Materials and methods: Descriptive study of SARs reported following administration of this vaccine to the PCVC between 2007 and 2011. Results: The cl…
