AbstractAim: Tumour necrosis factor α (TNFα) plays an important role in the pathogenesis of periodontitis. TNFα production is influenced by gene polymorphisms. The aim of this study was to evaluate links between genetic variants and chronic/aggressive periodontitis in a multivariate model.Subjects:
One hundred and twenty‐three periodontitis patients (chronic: n=54, aggressive: n=69) and 52 healthy controls without periodontitis were included in the study.Material and Methods: Single nucleotide polymorphisms (SNPs) c.−308G>A, c.−238G>A and haplotypes were analysed by a polymerase chain reaction with sequence‐specific primers (PCR‐SSP). The clinical investigation included smoking status, plaque and bleeding indexes, pocket depth and attachment loss.Results: Prevotella intermedia occurred more frequently in individuals positive for the −308GG/−238GG haplotype combination (Odds Ratio=2, 95% Confidence interval: 1.1–3.7, p=0.037, 1−β=61%). In binary logistic regression analyses, this TNFα haplotype could not be shown to be associated with periodontitis considering smoking, age, gender and approximal plaque index or subgingival bacterial colonization as confounding factors.Conclusions: Although the genetic background of TNFα could be shown to be associated with subgingival colonization with P. Intermedia, there is no evidence that it is an independent risk factor for periodontitis in multivariate models.
Use of high‐frequency ultrasound in the assessment of injectable dermal fillers
Authors: Young S. R. , Bolton P. A. , Downie J. 
Published: March 2008

Background: The use of dermal fillers for enhancing lips and reducing wrinkles is currently one of the fastest growing sectors of the cosmetic surgery market. There are numerous fillers available, some are synthetic others are isolated from biological material. Once injected the fillers have a varied lifespan ranging from months to years depending upon the material, site of injection and individual response. Current assessment techniques of filler performance are mostly limited to evaluations of the skin surface topography, and not to what is happening to the filler beneath the skin surface. The aim of this work was to see if high‐frequency ultrasound could be used to image and measure filler dimensions in situ.Method: This was a pilot study of six healthy female volunteers aged 36–53 visiting the surgical outpatients department of a hospital in Glasgow. Volunteers had been injected with filler material into their upper lip 6 months before the visit. The patients all had their upper lip scanned using high‐frequency ultrasound. The subsequent images were then assessed using the scanner software to assess the dimensions of the filler.Results: The filler material was clearly visible with the ultrasound and subsequently measurable in each scan. Each scan procedure was completed within a short time period meaning quantitative data could be acquired with minimum trauma to the volunteer. The scan images and data also provided valuable information for the volunteers and reinforced their perception of the fillers effect on their features.Conclusions: High‐frequency ultrasound scanning provides a non‐invasive, convenient and rapid technique for the assessment of filler performance. This pilot study produced three valuable pieces of information: • The ultrasound can image the filler material from which quantitative measurements can be made. • The technique is rapid and cost effective …• This investigation helped to reinforce the volunteer's perception of the filler effect.
Preliminary studies on the relationship among peel force, quantitative measures of skin damage and subjective discomfort

Published: March 2008

Background/aims: The ability to anticipate skin damage and subject/patient discomfort due to the removal of adhesive materials without human testing is currently limited. While standardized laboratory methods have been developed, their ability to model and predict the interaction with relevant living substrate is imperfect. The aim of this study was to assess the adhesion of various materials as a function of time using the abdomen as the body site, and determine if a relationship existed with skin damage and subject discomfort.Methods: Strips of six different materials used in medical devices and known to have different adhesive properties in the laboratory setting were tested in this study. The strips were adhered to the abdomens of normal volunteer subjects for varying periods of time. Peel force was measured under conditions developed to lessen the influence of skin elasticity. Disturbance of the skin barrier was assessed by measuring transepidermal water loss; erythema by reflectance L*a*b* measurements; skin cells removal by quantitation of dyed cells adhering to the test strips; and discomfort using subject self‐assessment.Results: When measured at times from 30 min to 72 h after application, the peel force was highest for materials at 30 min. The peel force for one of the six materials, designated F, was clearly higher than the others at time points from 30 min to 48 h after application. Interestingly, this material caused less disruption to the skin barrier and was reported to cause less discomfort.Conclusions: In this system, there was not a correspondence between adhesion as measured by peel force and skin damage or self‐report of discomfort. Further investigations will be required to establish the predictive value of other biophysical measurements and discomfort.
Musical hallucinosis: case reports and possible neurobiological models
Authors: Mocellin Ramon , Walterfang Mark , Velakoulis Dennis 
Published: March 2008

Objective:The perception of music without a stimulus, or musical hallucination, is reported in both organic and psychiatric disorders. It is most frequently described in the elderly with associated hearing loss and accompanied by some degree of insight. In this setting it is often referred to as ‘musical hallucinosis’. The aim of the authors was to present examples of this syndrome and review the current understanding of its neurobiological basis.Method:We describe three cases of persons experiencing musical hallucinosis in the context of hearing deficits with varying degrees of associated central nervous system abnormalities.Results:Putative neurobiological mechanisms, in particular those involving de-afferentation of a complex auditory recognition system by complete or partial deafness, are discussed in the light of current information from the literature.Conclusion:Musical hallucinosis can be experienced in those patients with hearing impairment and is phenomenologically distinct for hallucinations described in psychiatric disorders.
Photoprotection in Human Skin—A Multifaceted SOS Response†
Authors: Eller Mark S. , Asarch Adam , Gilchrest Barbara A. 
Published: March 2008

AbstractHuman skin has developed elaborate defense mechanisms for combating a wide variety of potentially damaging environmental factors; principal among these is UV light. Despite these defenses, short‐term damage may include painful sunburn and long‐term UV damage results in both accelerated skin aging and skin cancers such as basal cell carcinoma, squamous cell carcinoma and even malignant melanoma. While UV radiation damages many cellular constituents, its most lasting effects involve DNA alteration. The following sections briefly review UV‐inducible protective responses in bacteria and in skin, thymidine dinucleotides (pTT) as a powerful probe of DNA damage responses, and potential means of harnessing these inducible responses therapeutically to reduce the now enormous burden of cutaneous photodamage in our society.

Published: March 2008

SummarySerum soluble transferrin receptors (sTfR) concentration is a useful test in the diagnosis of childhood iron deficiency (ID). The aims of this study were to establish reference limits and to evaluate the diagnostic characteristics of sTfR in the diagnosis of ID in infants aged 9–12 months. In addition to mean erythrocyte cell volume, haemoglobin and ferritin measurements, sTfR concentration was measured in 179 healthy children in Estonia using the IDeA® and Tina‐quant® methods. Using the ID criteria of ferritin <10 μg/l, subjects were divided into healthy (n = 146) and ID (n = 33) groups. The reference limits (5th and 95th percentile) were calculated in the study group. We used receiver operating characteristic curves to find out the cut‐off values for the best diagnostic characteristics. The reference limits for sTfR were 1.5–2.7 mg/l in the IDeA® method and 4.1–7.8 mg/l in the Tina‐quant® method. The methods had poor agreement, the mean ratio with 95% limits of agreement was 2.9 (2.4–3.6). The best cut‐off value in order to identify ID by hypoferritinaemia in this population is an sTfR level >2.4 mg/l in the IDeA® (sensitivity 84%, specificity 94%) and an sTfR level >7.4 mg/l in the Tina‐quant (sensitivity 80%, specificity 92%). We conclude that sTfR concentration is an efficient tool in the diagnosis of ID, but that every method needs its own cut‐off value.
Aggressive periodontitis associated with Papillon‐Lefèvre syndrome: Report of a 14‐year follow‐up
Authors: De Freitas Aldevina C. , Assed Sada , Da Silva Léa A. B. , Silva Raquel A. B. 
Published: March 2008

ABSTRACTThis case report describes the periodontal management, therapeutic approach, and 14‐year follow‐up of a patient diagnosed with Papillon‐Lefèvre syndrome (PLS).A female child, diagnosed with PLS‐associated periodontitis at the age of 9 years and 11 months, presented with hyperkeratosis of the palms and soles, as well as generalized aggressive periodontitis. The dental treatment comprised standard periodontal debridement, scaling and root planing, instructions on oral hygiene, restorations, extraction of hopelessly affected teeth and a therapeutic use of antibiotics.The concomitant supportive periodontal therapy and antibiotic coverage could not stop the loss of periodontal attachment and destruction of the alveolar bone. Four years after treatment was initiated, the last remaining teeth were extracted and complete dentures were constructed. The dentures have been periodically replaced and the patient continues to return for follow‐up once a year.The combination of intensive periodontal treatment and antibiotic regimen only temporarily delayed periodontal disease progression and did not prevent loss of both primary and permanent teeth. The outcome of this long‐term follow‐up case report shows that management of PLS‐associated periodontitis is further complicated when the patient is first seen in the mixed dentition stage or later. In these situations, the chances of controlling the progression of periodontal breakdown and minimizing tooth loss are greatly reduced.

Culture studies on the rare brown alga Phaeostroma longisetum comb.nov. and its common relative P. pustulosum from Greenland
Authors: Pedersen Poul Møller 
Published: March 2008

Culture studies have shown that the rarely reported alga, Symphyocarpus longisetus, agrees with the type species of Phaeostroma with regard to its mode of formation of plurilocular sporangia, number of chloroplasts, and type of true hairs, and disagrees with the type species of Symphyocarpus. The new combination, Phaeostroma longisetum, is proposed. Unilocular sporangia are reported for the first time in this species. The life history is of the direct type under all conditions tested. The species grows and reproduces also at 15°C LD conditions although generally considered an arctic species. Phaeostroma pustulosum probably also has a homophasic, direct type of life history. The plants are either pseudoparenchymatous discs or branched filaments. The filamentous thalli are in agreement with the younger taxon Phaeostroma aequale (=Streblonema aequale).

Carcinomycetaceae: a new family in the Heterobasidiomycetes
Authors: Oberwinkler Franz , Bandoni Robert 
Published: March 2008

A group of holobasidiate mycoparasites, growing on Basidiomycetes, was studied by light– and electron microscopy. The parasites develop haustoria which penetrate the host–cells. Often a hypertrophic, gall–like growth of the host is induced by this parasitic interaction. Ana– and teleomorph stages and functions are highly diverse and not yet fully understood. Two species produce unique zygoconidia. The mechanism of spore abstriction on apically sterigmate holobasidia is hymenomycet–ous or gasteromycetous, and the basidiospores usually germinate by budding. Doli–pores without parenthesomes were found in three species. A heterobasidiomycetous relationship is proposed for the three genera, Christiansenia, Syzygospora, and Car–cinomyces gen. nov. Taxonomic considerations led to the proposal of a new family, the Carcinomycetaceae.This is Part 11 of a series, “Studies in Heterobasidiomycetes” of the Institut für Biologie I, Lehrstuhl Spezielle Botanik, Universitat Tubingen and the Department of Botany, University of British Columbia.
Cytology of oil–body cells in Ricciocarpus natans
Authors: Kronestedt Eva 
Published: March 2008

Oil–body cells in the liverwort Ricciocarpus natans are present as idioblasts and contain a single oil–body each. The limiting membrane of the oil–body has a tripartite dark–light–dark configuration. The layer facing the oil–body is thickest. Lipophilic globules are embedded in a matrix, which reacted positively for proteins, polysaccharides and lipids. The globules, which initially are minute, can coalesce to larger units, ultimately forming a single one. A peripheral layer was recognized by its different stainability. This layer was sometimes separated from the rest of the globule. Some seasonal variability was observed in the nature of the matrix and the amount of lipophilic material.The origin of the oil–body from the central vacuole was traced from the meristematic zone. The resemblance between the oil–body membrane and the tonoplast is in accordance with this origin. Smooth endoplasmic reticulum is extensively developed and seems to contribute material to the developing oil–body.

Authors: Seberg Ole 
Published: March 2008

A preliminary phylogeny of the Neotropical Acalypha is proposed, and previous infrageneric classifications commented upon. New views are presented on the floral morphology; the homology of the inflorescences and of the allomorphic female flower. The Galapagos Acalypha (Euphorbiaceae, Acalyphinae) are revised; the group is established as monophyletic and its relationships are shown. The sister–group is the Neotropical A. cuspidata–complex. Four species are recognized, viz. A. baurii Robinson & Greenman, A. wiggensii Webster, A. parvula J. D. Hooker, and A. abingdonii sp. nov. A. baurii is shown to be the sister–group of A. abingdonii + A. wigginsii+A. parvula, and A. abingdonii the sister–group of A. wigginsii + A. parvula. Brief accounts are given on nomenclatural history, aspects of morphology, chromosome numbers, geographical distribution (incl. the biogeography of the Galapagos Isles), ecology, pollination biology, and population structure.Se propone una filogenia preliminar para la Acalypha neotropical y se comenta la clasificacion infragenerica anterior.

The delimitation of Psora (Lecideaceae) and related genera, with notes on some species
Authors: Timdal Einar 
Published: March 2008

A new delimitation of the lichen genus Psora Hoffm. is proposed. The genus is mainly characterized by a squamulose thallus, an upper cortex of ‘Scheinrindentyp’, a hypothecium containing calcium oxalate, an amyloid hymenium containing anthra–quinones, the type of ascus and the type of pycnidium. The affinities of Psora to the genera Eremastrella, Psorula, and Xanthopsora and some squamulose species provisionally included in Lecidea are discussed. The genus Chrysopsora is reduced to syn–onomy with Psora, and the species Lecidea hedinii, L. scholanderi, and Psora petri to synonomy with Lecidea pulcherrima, Toninia tristis, and Lecidea lurida, respectively. The new combinations Lecanora scotopholis (Tuck.) Timdal, Psora hypotheja (Lamb) Timdal, P. subrubiformis (Vainio) Timdal, and P. vallesiaca (Schaerer) Timdal are proposed.New chemical data are given for a number of the species and chemical strains are recognized for the first time in Psora crenala, P. globifera, P. gresinonis, and P. rubifor–mis. Two new chemical strains of P. decipiens are recorded.
Contribution to the nomenclature of Cortinarius subgenus Dermocybe
Authors: Høiland Klaus 
Published: March 2008

The correct citation of Dermocybe as a subgenus of Cortinarius should be: Cortinarius (Fr.) Fr. subgen. Dermocybe (Fr.) Sam., since it was Saccardo who definitely treated Dermocybe at the subgeneric level under the genus Coriinarius. According to the rules of nomenclature, the type species of Dermocybe must be Coriinarius cinnamomeus (L.: Fr.) Fr. Cortinarius croceus (Schaeff.: Fr.) H˜jiland is invalidly combined, and the new combination Cortinarius croceus (Schaeff.) Heiland is proposed. A neotype for Cortinarius croceus is also proposed. Hydrocybe palustris Moser is invalidly published since the author simultaneously published an alternative name, Cortinarius palusiris Moser. Therefore the combinations Dermocybe palustris (Moser) Moser and Coriinarius palusiris (Moser) Nez‐dojminogo are invalid. The earliest legitimate name of the taxon is Cortinarius huronensis Ammirati & Smith. Cortinarius sphagneti Orton is a later homonym of Cortinarius shagneti Sing. The earliest legitimate name of the former taxon is Cortinarius tubarius Ammirati & Smith.
