Testing international dental maturation scoring system and population-specific Demirjian versions on Saudi sub-population
2013
Objectives: The purpose of this study was to test the applicability of the Demirjian method and revised versions for estimating chronological age (CA) from dental age (DA) in a sample of children. Study Design: A sample of 252 individuals of known age (4 to 14 yrs), sex (males: 125, females: 127), and ethnicity (Saudi) was collected. Each individual was aged using the original Demirjian method and revised versions, including Saudi, Kuwaiti, Belgian, and revised international curves. The differences between dental age and chronological age were analyzed using paired sample t-tests with Bonferroni corrections and multinomial regression tests at the 0.05 level of significance. Results: The res…
Weiterbildung CME: Depersonalisation/Derealisation - Krankheitsbild, Diagnostik und Therapie
2009
The present state of knowledge about depersonalization (DP) and derealization (DR) is reviewed with respect to classification, epidemiology, etiology, and therapy. Mild and transient DP-DR are considered to be common phenomena. The prevalence of depersonalization-derealization disorder (DP-DR-D) is estimated to be approx. 1-2% of the general population in the Western hemisphere. DP-DR-D is probably severely underdiagnosed. DP-DR-D is strongly associated with depression and anxiety disorders. It is suggested that symptoms of DP-DR indicate disease severity and negatively predict therapy outcome. Neurobiological and psychological models have shown that a disordered body schema and emotional a…
Establishing Equivalence or Non-Inferiority in Clinical Trials
2012
Background: An increasing number of clinical trials are being performed to show the absence of relevant differences between the effects of two treatments. The primary care physician makes use of the results of so-called equivalence studies, at least indirectly, practically every day. Equally important are active control clinical trials in which the efficacy of a new treatment has to be proven through demonstrating non-inferiority as compared to a standard treatment. Methods: Explanation of basic principles and statistical techniques with reference to the original literature; selective searches in the medical literature. Results: First of all, a suitable distributional parameter must be chos…

Ultraviolet reflectance of male nuptial colouration in sand lizards (Lacerta agilis) from the Pyrenees
2007
Abstract The evolutionary significance of lacertid colourations is relatively unexplored. However, several studies have demonstrated signalling by means of bright green colouration in Swedish Lacerta agilis males during the breeding season. Unfortunately, most of these studies have been based on human colour perception that differs in several ways from that of lizard. An important difference between human and lizard colour vision is the presence of an ultraviolet (UV) sensitive cone in lizards. The available evidence suggests that male sand lizards colorations do not reflect UV wavelengths, at least in Swedish populations. However, this study, based on objective (spectrophotometric) measur…
Effect of two different tooth bleaching techniques on microhardness of giomer
2016
Background Tooth bleaching is a safe and conservative treatment modality to improve the esthetic appearance of discolored teeth. One of the problems with the use of bleaching agents is their possible effect on surface microhardness of resin-based materials. The present study was carried out to evaluate the effect of in-office and at-home bleaching on surface microhardness of giomer. Material and Methods Seventy-five disk-shaped giomer samples (Beautifil II) were prepared and cured with a light-curing unit. The samples were randomly assigned to three groups (n=25). In group 1 (control), the samples were stored in distilled water for 14 days. The samples in groups 2 and 3 underwent a bleachin…
Empirically Grounded Clinical Interventions: Cognitive Versus Behaviour Therapy in the Individual Treatment of Obsessive-Compulsive Disorder: Changes…
2008
Clinical significance analyses of controlled studies comparing Exposure and Response Prevention (ERP) and Cognitive Therapy (CT) in the treatment of Obsessive-Compulsive Disorder (OCD) are scarce. The objective of this study is to compare the clinical efficacy of ERP and CT for OCD patients, and the usefulness of each in changing dysfunctional beliefs and thought control strategies at post-treatment and at a one-year follow-up. The two treatments were delivered on the basis of a routine clinical practice in a public-mental health service. Thirty-three OCD patients were randomly assigned to ERP or CT, and 29 completed the treatments (13 in ERP and 16 in CT). The ERP applied was in vivo, grad…
The genus thiobacillus: Physiology and industrial applications
1983
This review deals with different aspects concerning the genus Thiobacillus as an obligat chemoautotroph able to oxidize reduced anorganic sulphur compounds. There are given the following topics: physiology of the genus (nutritional requirements, enzymatic complexes for sulphur oxidation, energy generation, reductive CO2 assimilation and growing in presence of organic compounds). The ecological significance of Thiobacilli in the sulphur cycle in Nature is presented. The industrial applications of Thiobacilli in respect to the leaching processes that allow the recovery of metals through oxidation and solubilization from low-grade ores are discussed, with special reference to copper and uraniu…
Clinical significance of the polymerase chain reaction (PCR) assay in chronic HBV carriers
1992
PCR was evaluated as a clinical tool for use in accurate identification of the specific etiologic agent in chronic HBV carriers. The method was found to be valuable in diagnosis and for monitoring therapy, as well as for elucidation of genotypic variants of HBV in chronic HBV cases. By this means an HBV defective variant with alterations in the preSl/preS2 sequence was detected and is consequently described here.
