The aim of this study was to evaluate changes in the pharyngeal airway in growing children and adolescents and to compare these with a group of children who received activator-headgear Class II treatment. The sample consisted of 64 children (32 males and 32 females), 32 had a combined activator-headgear appliance for at least 9 months (study group) followed(More)
BACKGROUND Transplant recipients (TR) have a dramatically increased risk for widespread epithelial neoplasms of the skin. Thus, there is a need to treat initial stages of these neoplasms such as actinic keratoses (AK) and Bowen's disease (BD) to prevent progression to invasive and potentially fatal squamous cell carcinoma. Topical photodynamic therapy (PDT)(More)
The aim of this clinical study was to compare the internal gaps between abutment teeth and posterior fixed partial dentures (FPDs) fabricated utilizing milled zirconia and cast gold-alloy frameworks. As part of an ongoing randomized controlled clinical trial, 32 three-unit FPDs (16 zirconia and 16 metal-ceramic) in 25 patients were randomly selected for(More)
PRINCIPLES In view of growing concern in recent years regarding medication errors as causes of adverse drug events (ADEs), we explore the frequency and characteristics of error-associated ADEs in medical inpatients. METHODS All patients with ADEs or ADErelated hospital admission in a cohort of medical inpatients identified by "event monitoring" (SAS/CHDM(More)
Fifty-three posterior glass fibre-reinforced composite inlay-fixed partial dentures (IFPDs) in 36 patients were followed for 5 yr. For statistical analysis, one IFPD per patient was randomly selected. The survival rate and influence of discrete predictors (gender, location) and continuous variables (age, abutment surfaces) were determined. Clinical(More)
In the present paper we consider compound Poisson approximation by Stein's method for dissociated random variables. We present some applications to problems in system reliability such as k-runs, counting isolated vertices in the rectangle lattice on the torus as well as consecutive 2-systems, coloured graphs, birthday problems, connected s-systems and two(More)
AIMS To explore drug exposure, frequency of adverse drug reactions (ADRs), types of ADRs, predisposing risk factors and ADR-related excess hospital stay in medical inpatients. METHODS Structured data regarding patient characteristics, 'events' (symptoms, laboratory results), diagnoses (ICD10) and drug therapy were collected using a computer-supported data(More)
BACKGROUND Echocardiographic characteristics typical of isolated left ventricular noncompaction (IVNC) have been well defined. The aim of this study was to validate diagnostic criteria of IVNC in valvular or hypertensive heart disease (HHD) or dilated cardiomyopathy. METHODS We conducted a retrospective analysis of records and blind review of videotapes(More)
OBJECTIVES The aim of the present study was to test whether or not immediate implantation leads to more biological complications, when performed at extraction sockets of teeth exhibiting periapical pathology compared with teeth not exhibiting periapical pathology. MATERIALS AND METHODS In 17 consecutively admitted patients, immediate implant placement was(More)
Urinary incontinence due to acquired urethral sphincter incompetence is a common side effect of spaying, for which the underlying cause remains unknown. Spaying not only results in a significant reduction in the urethral closure pressure within 1 year but also in an increase in the plasma gonadotropin concentrations. To investigate the possible link between(More)
