Management of peripheral facial nerve palsy

Peripheral facial nerve palsy (FNP) may (secondary FNP) or may not have a detectable cause (Bell’s palsy). Three quarters of peripheral FNP are primary and one quarter secondary. The most prevalent causes of secondary FNP are systemic viral infections, trauma, surgery, diabetes, local infections, tumor, immunological disorders, or drugs. The diagnosis of FNP relies upon the presence of typical symptoms and signs, blood chemical investigations, cerebro-spinal-fluid-investigations, X-ray of the scull and mastoid, cerebral MRI, or nerve conduction studies. Bell’s palsy may be diagnosed after exclusion of all secondary causes, but causes of secondary FNP and Bell’s palsy may coexist. Treatment of secondary FNP is based on the therapy of the underlying disorder. Treatment of Bell’s palsy is controversial due to the lack of large, randomized, controlled, prospective studies. There are indications that steroids or antiviral agents are beneficial but also studies, which show no beneficial effect. Additional measures include eye protection, physiotherapy, acupuncture, botulinum toxin, or possibly surgery. Prognosis of Bell’s palsy is fair with complete recovery in about 80% of the cases, 15% experience some kind of permanent nerve damage and 5% remain with severe sequelae

Y chromosomal STR locus DYS385 in azoospermic and fertile men from the aegean region of Turkey: Is there any forensic relevance?

The DYS385 locus, consisting of two linked short tandem repeat (STR) subloci, is the polymorphic marker on the Y chromosome. The distribution of DYS385 genotypes was studied in 51 fertile and 49 azoospermic male individuals from the Aegean Region of Turkey. Genotype 14-17 was the most frequently observed genotype, and the gene diversity value of the Aegean population (n = 100) was 0.946 in this study. Results of the analyses show that there is a statistically significant difference between azoospermic and fertile males in terms of the DYS385 polymorphism. In addition, the results demonstrate that the DYS385 locus is very useful for human identification in forensic cases and paternity tests in the Aegean Region of Turkey

Electric Field Effects in Self-Propagating High-Temperature Synthesis under Microgravity Conditions

Self-propagating high-temperature synthesis (SHS) has been used to form many materials. SHS generally involves mixing reactants together (e.g., metal powders) and igniting the mixture such that a combustion (deflagration) wave passes though the mixture. The imposition of an electric field (AC or DC) across SHS reactants has been shown to have a marked effect on the dynamics of wave propagation and on the nature, composition, and homogeneity of the product . The use of an electric field with SHS has been termed "field-assisted SHS". Combustion wave velocities and temperatures are directly affected by the field, which is typically perpendicular to the average wave velocity. The degree of activation by the field (e.g., combustion rate) is related to the current density distribution within the sample, and is therefore related to the temperature-dependent spatial distribution of the effective electrical conductivity of reactants and products. Furthermore, the field can influence other important SHS-related phenomena including capillary flow, mass-transport in porous media, and Marangoni flows. These phenomena are influenced by gravity in conventional SHS processes (i.e., without electric fields). As a result the influence of the field on SHS under reduced gravity is expected to be different than under normal gravity. It is also known that heat loss rates from samples, which can depend significantly on gravity, can influence final products in SHS. This research program is focused on studying field-assisted SHS under reduced gravity conditions. The broad objective of this research program is to understand the role of an electric field in SHS reactions under conditions where gravity-related effects are suppressed. The research will allow increased understanding of fundamental aspects of field-assisted SHS processes as well as synthesis of materials that cannot be formed in normal gravity

Age-specific seroepidemiology of hepatitis A, B, and E infections among children in Istanbul, Turkey

This study was performed for evaluation of seroprevalence of hepatitis A, B, and E among children in Istanbul, Turkey. The study group included 909 children who were 6 months-15 years of age. The children were separated to three age groups: Group 1 (6 months-4.9 years; n = 321), Group 2 (5.0-9.9 years; n = 318), and Group 3 (10.0-15.0 years; n = 270). Group 1 was divided to two subgroups for evaluation of the maternal antibody sera (6 months-2 years and over 2 years). Serum IgG anti-HAV, anti-HBc, and anti-HEV were tested by commercial ELISA kits. The data were studied by multivariant analysis. In all subjects, seroprevalence of hepatitis A, B, and E were determined as 29, 15.9, and 2.1% respectively. The prevalence of hepatitis A increased with age (p 0.05). The seroprevalence of hepatitis E virus infection was higher in Group 1 (3.7%) than Group 3 (0.3%; p < 0.05). In Group 1 first subgroup, between 6 month and 2 year, antibody levels were 12.2, 17.3, and 4.8% respectively, for anti-HAV IgG, anti-HBc IgG and anti-HEV IgG. Hepatitis A and B infection is a community health problem, but hepatitis E infection is low in children in Istanbul, Turkey. The high positive rate in Group 1 for IgG anti-HEV may be due to maternal antibodies
