INTRODUCTION Data regarding the long-term outcome of catheter ablation in patients with nonpulmonary vein (NPV) ectopy initiating atrial fibrillation (AF) are limited. We aimed to evaluate the long-term result of patients with AF who had NPV triggers and underwent catheter ablation. METHODS AND RESULTS The study included 660 consecutive patients (age 54 ± 11 years old, 477 males) who had unde...

OBJECTIVE Administrative health data are important for health services and outcomes research. We optimised and validated in intensive care unit (ICU) patients an International Classification of Disease (ICD)-coded case definition for sepsis, and compared this with an existing definition. We also assessed the definition's performance in non-ICU (ward) patients. SETTING AND PARTICIPANTS All adu...

BACKGROUND Previously presented new electrocardiography (ECG) algorithm for localization of arrhythmogenic focus (AFo) in right ventricular outflow tract (RVOT) was based on spontaneous arrhythmia QRS morphology analysis. The aim of this study was to estimate the clinical value of our RVOT algorithm in a prospective study. METHODS AND RESULTS Algorithm validation was made on 62 patients with ...

Karst rocky desertification is a special kind of land desertification developed under violent human impacts on the vulnerable ecogeo-environment in karst ecosystem. The process of karst rocky desertification results in simultaneous and complex variations of many interrelated soil, rock and vegetation biophysical parameters, rendering it difficult to develop simple and robust remote sensing mapp...

OBJECTIVE Various factors have been claimed to predict outcome of afebrile seizures in children. This study was aimed to find out the predictors of poor seizure control in children at a resource limited setting. MATERIALS & METHODS This prospective study was done from July 1st, 2009 to January 31st, 2012 at B.P. Koirala Institute of Health Sciences, Nepal. Children (1 month-20 yr of age) with...

Aim of this study was to evaluate the performance of saline hydrosonography (HSGM) (also known as saline infusion sonography (SIS)) against transvaginal ultrasound scan (TVS) and hysteroscopy in the diagnosis of uterine cavity lesions. Diagnostic hysteroscopy with biopsy is considered as the "gold standard" to diagnose intrauterine abnormalities. The introduction of HSGM has improved the diagno...

OBJECTIVE The aim of this study was to evaluate the use of a Risk of Malignancy Index (RMI) in primary evaluation of patients with adnexal masses. METHODS The RMI is based on menopausal status, ultrasonographic findings, and serum CA 125 level. A cutoff level of 200 was chosen as the threshold for referral for centralized primary surgery. This setup was evaluated by sensitivity, specificity, ...

Negative-pressure ventilation: is there still a role? A. Corrado, M. Gorini. #ERS Journals Ltd 2002. ABSTRACT: Negative-pressure ventilation (NPV) was the primary mode of assisted ventilation for patients with acute respiratory failure until the Copenhagen polio epidemic in the 1950s, when, because there was insufficient equipment, it was necessary to ventilate patients continually by hand via ...

Objectives To study positive (PPV) and negative predictive value (NPV) of positron emission tomography with computed tomography (PET-CT) scans in determining malignancy in skull base lesions and perform a systematic literature review for optimal PET-CT interpretation. Design Retrospective case series and systematic literature review of the current English literature. Setting Tertiary referral a...

OBJECTIVE To validate a revised version of the paediatric South African Triage Scale (SATS) against admission as a reference standard and compare the sensitivity of triage using: (i) clinical discriminators; (ii) an age-appropriate physiological composite score; and (iii) a combination of both. METHODS A prospective cohort study was undertaken validating the revised paediatric SATS against ou...
