Arytenoid dislocation: Diagnosis and treatment
Authors: Sataloff Robert Thayer , Bough I. David , Spiegel Joseph R. 
Published: October 2006

AbstractDisruption of the cricoarytenoid joint is a relatively uncommon event, according to the world literature. Only 31 reported cases of arytenoid dislocation or subluxation exist other than the 26 cases described in this paper. Often cases are misdiagnosed as vocal fold paralysis. Knowledge of the signs and symptoms of arytenoid dislocation aids in correct diagnosis and early treatment. Even when diagnosis has been delayed, surgery may be highly effective. Familiarity with state‐of‐the‐art diagnostic techniques and new concepts in management helps optimize the chances for good voice quality.
Anterior commissure microwebs associated with vocal nodules: Detection, prevalence, and significance
Authors: Ford Charles N. , Bless Diane M. , Campos Guillermo , Leddy Mark 
Published: October 2006

AbstractVocal fold nodules are a common cause of dys‐phonia generally attributed to vocal abuse. Anterior commissure microwebs have been reported as an incidental finding in surgical patients with nodules. In a series of 105 nodule patients evaluated at the University of Wisconsin Clinical Science Center voice laboratory (1987–1992), 11 microwebs were identified. Ten of these microweb patients were among the 20 nodule patients who did not respond to voice therapy and underwent microsurgery. In patients with nodules whose hoarseness is refractory to voice therapy, symptoms that occur early in life suggest the presence of occult vocal fold pathology. Microweb detection requires a high index of suspicion, observation during maximal vocal fold abduction, and clearance of secretions from the anterior commissure. Definitive identification is facilitated by gentle separation of the anterior vocal folds during direct microlaryn‐goscopy. The presence of these tiny shelves of tissue might be coincidental, or they might represent another expression of the tissue response to traumatic factors known to produce vocal nodules. We found little difference in vocal function parameters between two similar groups of nodule patients, one with and one without associated microwebs. Further work is needed to determine the significance of microwebs.
Diagnostic problems in patients with benign paroxysmal positional vertigo
Authors: Norréa Marcel E. 
Published: October 2006

AbstractThe steps of the examination procedure applied for a correct diagnosis of benign paroxysmal positional vertigo (BPPV) are reviewed. A precise diagnosis is important in view of treatment of this type of vertigo by rehabilitation therapy. Clinical experience supports the concept that the diagnosis has to be based not only on a typical history, but also on the presence of a reproducible vertigo and paroxysmal positioning nystagmus. In the procedure applied in the department, this nystagmus can be reproduced by the Dix‐Hallpike maneuver under Frenzel's glasses, during electronystagmography (ENG) recording in the position tests, or it can be present in the vestibular habituation training test battery (a battery of 19 maneuvers applied for defining the adequate exercises in the rehabilitation treatment for BPPV). Analysis of the reviewed data in 95 patients showed that one third of the patients described the vertigo in a rather atypical way, while the further testing revealed a typical BPPV. This experience denies any absolute reliability to only history. In fact, only the finding of such a paroxysmal positioning nystagmus is conclusive for confirming BPPV. However, also the presence of such a nystagmus appeared not to be a constant datum, so that in some patients more than one examination was necessary to come to a reliable diagnosis. It is obvious that, for detecting a paroxysmal positioning nystagmus, ENG is less reliable than the Dix‐Hallpike maneuver under Frenzel's glasses.
Functional Polymorphisms in the Matrix Metalloproteinase‐9 Gene in Relation to Severity of Chronic Periodontitis
Authors: Holla Lydie Izakovicova , Fassmann Antonin , Mužík Jan , Vanek Jiri , Vasku Anna 
Published: October 2006

Background: Members of the matrix metalloproteinase (MMP) family are implicated in the chronic remodeling in periodontal diseases. Therefore, we performed a case‐control study to investigate a plausible association between susceptibility to chronic periodontitis (CP) and the polymorphisms in the MMP‐9 (gelatinase B) gene.Methods: Using polymerase chain reaction with subsequent restriction analyses, MMP‐9 −1562C/T and R+279Q variants were determined in 304 subjects (169 patients with CP, 76 with a mild to moderate form and 93 with severe generalized CP, and 135 age‐ and gender‐matched unrelated control subjects).Results: The distribution of the MMP‐9 −1562C/T and R+279Q genotypes and alleles did not significantly differ between cases and controls. However, the frequency of the T variant at position −1562 was marginally higher in patients with severe disease compared to those with mild to moderate forms (P <0.05; Pcorr >0.05). In further analysis, the −1562T allele was associated with a severe form of CP in men (odds ratio: 3.87; 95% confidence interval: 1.40 to 10.65; P <0.01 and Pcorr <0.05 for allele; P <0.05 and Pcorr >0.05 for genotype) but not in women.Conclusion: These findings suggest that genetic polymorphisms of the MMP‐9 gene are not associated with the susceptibility to CP in the Czech population; however, the promoter variant may influence the severity of the disease in men.

Published: October 2006

Background: Altered glycosylation of immunoglobulin G (IgG) has been found to affect certain immunological activities of IgG and to correlate with increased inflammation in various disease states. This work deals with the changes in distribution and galactosylation of IgG subclasses present in saliva and gingival crevicular fluid (GCF) of patients with initial and advanced periodontitis and of normal controls.Methods: IgG subclasses were quantified by dot‐blot assay, and the degrees of expression of galactose in the total IgG and its individual subclasses were estimated by lectin immunoblot assay after sodium dodecyl sulfate‐polyacrylamide gel electrophoresis (SDS‐PAGE) separation of IgG and by capture enzyme‐linked immunosorbent assay (ELISA), using biotinylated Ricinus communis (RCA‐I) and Bandeiraea simplicifolia (BS‐II) lectins.Results: The distribution of IgG subclasses in both fluids was found to differ in periodontal patients compared to normal controls. In the periodontitis saliva and GCF, the IgG2 subclass dominated quantitatively, regardless of periodontal status. However, galactose was found to be expressed in IgG heavy chains in normal controls and patients with initial periodontitis but not, or at barely detectable levels, in advanced periodontitis.Conclusion: The results suggest that the shift toward hypogalactosylated glycoforms may occur during the process of inflammation of the gingiva.
Microwave saturation of EPR spectra of oxidised coal
Authors: Pilawa Barbara , Więckowski Andrzej , Pietrzak Robert , Wachowska Helena 
Published: October 2006

AbstractMicrowave saturation of multi-component EPR spectra of oxidized lignite Mequinenza (Spain) with a carbon content of 65.1 wt % and with a high sulphur content of 10.3 wt % was studied. The coal was oxidized with nitric acid (NHO3), peroxyacetic acid (PAA), and in O2/Na2CO3 system. Three different groups of paramagnetic centres exist in the coal samples analyzed. The EPR spectrum of the demineralised coal was a superposition of broad Gauss (ΔB pp = 0.75 mT), broad Lorentz 1 (ΔB pp = 0.42 mT) and narrow Lorentz 3 lines (ΔB pp = 0.08 mT). The three EPR components with linewidths: 0.58–0.77 mT (Gauss line), 0.30–0.39 mT (Lorentz 1 line) and 0.05–0.06 mT (Lorentz 3 line) were recorded for the oxidized coal. The g-values were obtained for the samples studied in the ranges 2.0043–2.0046 (Gauss lines), 2.0035–2.0038 (Lorentz 1 lines) and 2.0032–2.0034 (Lorentz 3 lines). The broad Gauss and Lorentz 1 lines saturate at low microwave powers. The narrow Lorentz 3 lines of demineralised coal were not saturated at microwave power from the range considered. After the coal oxidation with HNO3, PAA and in O2/Na2CO3 system, the microwave saturation of the narrow Lorentz 3 lines was also observed, which indicated a degradation of the multi-ring aromatic structures upon oxidation.
Single‐particle motion and heat transfer in fluidized beds
Authors: Wong Yee Sun , Seville Jonathan P. K. 
Published: October 2006

AbstractFluidized beds are particularly favored as chemical reactors because of their ability to exchange heat through immersed heat‐exchange surfaces. However, little is known about how the heat‐exchange process works on a single‐particle level. The most commonly applied theory of fluidized bed heat exchange is that developed by Mickley and Fairbanks in the 1950s—the so‐called packet model. The work described in this article is an attempt to understand the process of heat transfer by solids convection, using positron emission particle tracking to follow the trajectory of a single tracer particle in the bed. In particular, the residence time of particles in the vicinity of the surface is determined here for the first time. Using these data, the observed heat‐transfer variations are interpreted mechanistically. © 2006 American Institute of Chemical Engineers AIChE J, 2006

AbstractTo analyze the contribution of the Czech population to the Y‐chromosome diversity landscape of Europe and to reconstruct past demographic events, we typed 257 males from five locations for 21 UEPs. Moreover, 141 carriers of the three most common haplogroups were typed for 10 microsatellites and coalescent analyses applied. Sixteen Hg's characterized by derived alleles were identified, the most common being R1a‐SRY10831 and P‐DYS257*(xR1a). The pool of haplogroups within I‐M170 represented the third most common clade. Overall, the degree of population structure was low. The ages for Hg I‐M170, P‐DYS257*(xR1a), and R1a‐SRY10831 ap peared to be comparable and compatible with their presence during or soon after the LGM. A signal of population growth beginning in the first millennium B.C. was detected. Its similarity among the three most common Hg's indicated that growth was characteristic for a gene pool that already contained all of them. The Czech population appears to be influenced, to a very moderate extent, by genetic inputs from outside Europe in the post‐Neolithic and historical times. Population growth postdated the archaeologically documented introduction of Neolithic technology and the estimated central value coincides with a period of repeated changes driven by the development of metal technologies and the associated social and trade organization.

Carabelli's trait and tooth size of human maxillary first molars
Authors: Harris Edward F. 
Published: October 2006

AbstractCarabelli's trait is a morphological feature that can occur on the protocone of human maxillary molars. This study tests the hypothesis that Carabelli's trait is correlated statistically with the dimensions of the crown's four principal cusps or whether, as a cingular feature, the trait truly accretes onto an otherwise unaffected crown. Computer‐assisted image analysis was used to measure the 6 intercusp distances and 12 angular relationships among cusp tips on the permanent first molar of 300 young adult American whites. Carabelli's complex was scored using an 8‐grade ordinal scheme. Crown size was quantified in three ways, namely as 1) maximum mesiodistal and buccolingual diameters, 2) the 6 intercusp distances, and 3) the 12 angular cusp arrangements. There was no sex difference in the morphological expression of Carabelli's trait in this sample. Overall crown size and intercusp distances were significantly and progressively larger in molars with larger Carabelli's trait expressions. There are graded size responses between crown size (mesiodistal and buccolingual diameters), sizes of the four principal cusps, and morphological stage of Carabelli's complex, though the statistical relationships are appreciably stronger in males than females. Carabelli's trait occurs preferentially in larger molars. In contrast, angular (shape) relationships among cusp tips are not discernibly affected by trait size in either sex. There is the situation, then, that Carabelli's trait is developmentally correlated with crown size, but with no apparent alteration of cusp arrangements, suggesting that the increases are isometric across the occlusal table. Why the association is much weaker in females remains speculative, but these data provide yet another line of evidence that, within a population, tooth size is associated in a positive fashion with crown complexity.

Self‐Assembled Aggregates and Molecular Bilayer Films of a Double‐Chain Fullerene Lipid: Structure and Electrochemistry
Authors: Murakami Hiroto , Nakanishi Takashi , Morita Makoto , Taniguchi Naoya , Nakashima Naotoshi 
Published: October 2006

AbstractThe self‐aggregation behavior of C60 fullerenes that bear two octadecyl chains (lipid 1) as well as the structures and electrochemical properties of cast films of 1 are described. We also examined the self‐aggregation behavior in organic solvents of three previously reported compounds: C60 with three each of hexadecyl (lipid 2), tetradecyl (lipid 3), or dodecyl (lipid 4) chains. The fullerene lipids in alcohols spontaneously formed spherical aggregates, whose diameters are related to the alkyl‐chain lengths, concentrations of the fullerene lipids, and the solvent polarity. The morphologies of the aggregates showed temperature dependence. Cast films of 1 formed multimolecular bilayer structures that undergo a phase transition typical of lipid bilayer membranes. The electrochemistry of cast films of 1 on an electrode in aqueous medium exhibits temperature dependence.

Published: October 2006

Abstract

Background
Publications in peer-reviewed journals are the main determinants of research rating and funding. The present study assesses worldwide scientific contributions in the field of surgical research.

Methods
Fifteen major surgical journals were selected for a bibliometric search in Medline/PubMed over a 6-year period (2000–2005). All articles with abstracts were totalled according to country of corresponding author. Publications (total and corrected for population size) and journal impact factor were assessed according to country.

Results
A total of 18 717 articles were identified. Fifteen countries generated 88·8 per cent of these: the USA produced 42·1 per cent, Japan 9·1 per cent and the UK 7·6 per cent. When corrected for population size, the Netherlands, Sweden and Switzerland topped the ranking; the USA was sixth. Ireland and Switzerland scored the highest mean impact factor.

Conclusion
The USA is the most productive country in terms of absolute number of surgical publications in the selected journals. However, when population size is taken into consideration, certain smaller European countries were more prolific.
