Objective— To report outcomes after cellophane banding of single congenital portosystemic shunts in dogs and cats.Study Design— Retrospective study of sequential cases.Animals— One hundred and six dogs and five cats.Methods— Medical records were reviewed for breed, sex, age at surgery, shunt anatomy, results of pre‐ and postoperative biochemical analysis, development of postligation neurologic dysfunction, portal hypertension or other serious complications, and the owners' perception of their animal's response to surgery.Results— Ninety‐five dogs and all 5 cats had extrahepatic shunts. Eleven dogs had intrahepatic shunts. Six dogs (5.5%) died as a result of surgery from portal hypertension (2 dogs), postligation neurologic dysfunction (2), splenic hemorrhage (1) and suspected narcotic overdose (1). Serious complications were more common in dogs with intrahepatic shunts than those with extrahepatic shunts (P=.002). Postligation neurologic dysfunction necessitated treatment in 10 dogs and 1 cat; 8 dogs and the cat survived. Clinical signs attributed to portosystemic shunting resolved or were substantially attenuated in all survivors. Postoperative serum bile acid concentrations or results of ammonia tolerance testing were available for 88 animals; 74 (84%) were normal and 14 (16%) were abnormal. Multiple acquired shunts were documented in two animals.Conclusions— Cellophane banding is a safe and effective alternative to other methods of attenuation.Clinical Relevance— Slow occlusion of portosystemic shunts using a variety of methods is being evaluated world wide. Cellophane banding is a relatively simple procedure with comparable safety and efficacy to previously reported techniques.

Authors: Sutter W. Wesley , Hardy Joanne 
Published: November 2004

Objectives—To describe standing laparoscopic repair of mesoduodenal rent inaccessible by ventral median celiotomy.Study design—Clinical case report.Sample population—A 6‐year‐old Thoroughbred broodmare with a right displacement of the dorsal colon and small intestinal incarceration in a mesoduodenal rent.Methods—Two days after correction of a right dorsal displacement of the ascending colon, small intestinal incarceration, and partial closure of mesoduodenal rent, standing left and right flank laparoscopy was used to explore the abdomen to identify the mesoduodenal defect. The mesenteric rent was repaired from right flank portals by approximation with hemostatic clips.Results—Approximation of the mesoduodenal rent was achieved with laparoscopic clips. No further complications or signs of abdominal pain occurred over the following year.Conclusions—Mesenteric rents in the mesoduodenum can be repaired by laparoscopic techniques in the standing horse.Clinical Relevance—Use of laparoscopic techniques in the standing horse should be considered for mesoduodenal rents that are not accessible form a ventral median celiotomy.
A systematic review of the influence of different titanium surfaces on proliferation, differentiation and protein synthesis of osteoblast‐like MG63 cells
Authors: Bächle Maria , Kohal Ralf J. 
Published: November 2004

AbstractObjectives: Titanium is the standard material for dental and orthopaedical implants. The good biocompatibility has been proven in many experimental and clinical investigations. Different titanium topographies were tested in vitro using different cell culture models. The aim of this systematic review was to evaluate and summarize the medical/dental literature to assess on which kind of titanium surface structure the osteoblast‐like osteosarcoma cells MG63 show the best proliferation and differentiation rate, and the best protein synthesis.Methods: A systematic search was carried out using different on‐line databases (PubMed, Web of Science, Cochrane Library, International Poster Journal), supplemented by handsearch in selected journals and by examination of the bibliographies of the identified articles. Inclusion and exclusion criterias were applied when considering relevant articles. Studies which met the inclusion criteria were included and data extraction was undertaken by one reviewer.Results: The search yielded 348 references. Nine articles referring to nine different studies were relevant to our question. Additionally 8 less relevant articles were identified. It was found that regularly textured surfaces of pure titanium with Ra values (average roughness) of around 4 μm are well‐accepted by MG63 cells.Conclusions: The surfaces and culture conditions vary widely. Therefore it is still difficult to recommend one particular surface. It seems that there are no differences in cell proliferation and differentiation on surfaces treated by blasting and etching. Standardization in fabrication and size of the different test surfaces as well as homogeneity in culture times and plating densities should be aspects for future research.
The use of porous calcium phosphate scaffolds with transforming growth factor beta 1 as an onlay bone graft substitute
Authors: Huse Robert O. , Quinten Ruhe P. , Wolke Johannes G. C. , Jansen John A. 
Published: November 2004

AbstractObjectives: Autogeneous bone grafting is regarded to be the golden standard for onlay grafts, but it requires a harvesting procedure and the remodeling pattern over time is unpredictable. New materials are constantly being sought to overcome these problems. An in vivo experiment was carried out to evaluate whether (1) porous calcium phosphate cement is a suitable biomaterial for onlay bone grafting, and (2) the addition of transforming growth factor beta 1 (TGF‐β1) accelerates de novo bone formation inside the cement porosity.Material and methods: A carrier of porous calcium phosphate cement (Calcibon®) was designed and 16 rats received one preshaped implant each. In 8 out of 16 implants 0.75 μg TGF‐β1 was applied. The animals were killed after 4 weeks and the characteristics of tissue ingrowth into the onlay graft were evaluated.Results: Histologic and quantitative histomorphometrical measurements demonstrated osteoid‐like tissue formation in both experimental groups. The addition of TGF‐β1 did not induce significantly more osteoid‐like tissue formation. On the other hand, in TGF‐β‐loaded implants, a higher number of pores contained an inflammatory infiltrate.Conclusion: This study indicated that porous calcium phosphate cement is a promising material for clinical situations where bone formation has to be supported.

Published: November 2004

Abstract:Cardiac disease is the primary cause of mortality in β‐thalassemia patients. Except for ventricular dysfunction and pulmonary hypertension that represent the main forms of heart disease in these patients, valvular abnormalities including valvular regurgitation, endocardial thickening and calcification and mitral valve prolapse have also been described. Here we present two patients with thalassemia major and mitral chordal rupture, a previously undescribed abnormality in this population. Pathogenesis of this finding may involve thalassemia‐related pseudoxanthoma elasticum‐like syndrome, a diffuse elastic tissue defect, which is observed with a notable frequency in these patients and has been associated with numerous cardiovascular complications, including valvular ones.

Published: November 2004

Problem:  To assess the association between antibodies to Chlamydia trachomatis heat shock proteins 60 and 10 (Hsp60 and Hsp10) and subfertility in a general population sample.Method of Study:  A nested case (n = 146)–control (n = 278) study in a population‐based birth cohort. Serum immunoglobulin (Ig)G and IgA antibodies against C. trachomatis Hsp60 and Hsp10, explanatory factors, were measured by enzyme immunoassay, using recombinant proteins as antigens. The main outcome variable was subfertility (time to pregnancy ≥12 months).Results:  The prevalence and medians of serum IgA antibodies to Hsp60 and Hsp10 were significantly higher in the female partners of subfertile couple than in their fertile controls. On the contrary, among male partners of subfertile couple, especially among smokers serum antibody levels to Hsp antigens were lower than in the controls.Conclusion:  The results indicate a serological association of antibodies to chlamydial Hsp antigens with female subfertility in a population‐based sample.
Identification of the M‐CSF Receptor in Endometriosis by Immunohistochemistry and RT‐PCR

Published: November 2004

Problem:  The aim of this paper is to provide further evidence that the dystopic proliferation of endometriotic epithelia is caused by the stimulation of peritoneal macrophages. It is essential to show that endometriotic epithelial cells express the macrophage colony‐stimulating factor receptor (M‐CSFR) which binds the M‐CSF produced by the peritoneal macrophages.Method of study:  For the detection of M‐CSFR, samples of ectopic endometrium (n = 79) and eutopic endometrium (n = 18) were compared. The specimens were gained at operative laparoscopy in the proliferative phase of the cycle. Cryostat sections were used for immunohistochemical detection. For in vitro reverse transcriptase polymerase chain reaction (RT‐PCR) tests, the tissue was immediately shock frozen on paraffin sections. For the in situ RT‐PCR technique the specimens were placed in a para‐formaldehyde solution, embedded in paraffin and later processed. The Gene Amp 1000 in situ PCR system (Perkin Elmer) was used as the thermal cycler.Results:  M‐CSF and the M‐CSF receptor are present in eutopic and ectopic endometrium. Qualitatively, with both PCR techniques we found the M‐CSF receptor to be present in all samples examined. Using the histochemical detection technique, the M‐CSF receptor was found in nearly 70% of endometriosis patients compared with a statistically significant lower percentage in normal endometrium.Conclusions:  The in situ RT‐PCR technique and immunohistochemistry elaborated the need to trace the cellular sources of the M‐CSF receptor. The identification of the M‐CSF receptor in endometriotic tissue and in endometrium is apt to open a new experimental field in endometriosis research.

Structured AbstractAuthors – Verstrynge A, Ghesquiere A, Willems G.Objectives – To clinically evaluate the bond characteristics of the adhesive precoated ceramic (APC) Clarity bracket and compare it with the uncoated Clarity bracket used with Transbond XT bonding system.Design – A randomized clinical trial.Settings and Sample Population – Department of Orthodontics, Katholieke Universiteit Leuven. Twenty patients requiring bonded fixed orthodontic appliance from central incisor to second bicuspid.Experimental Variable – APC Clarity brackets were bonded in the first and fourth quadrant of group 1 and in the second and third quadrant of group 2. Uncoated Clarity brackets were bonded with Transbond XT in the second and third quadrant of group 1 and in the first and fourth quadrant of group 2.Outcome Measure – During orthodontic treatment, bracket failures were registered. At debonding, the tooth surfaces were intraorally scored according to the Adhesive Remnant Index.Results – During treatment one tie wing fractured in the APC group and no bond failures occurred. At debonding, no significant differences between the APC and Transbond XT could be shown in any of the quadrants.Conclusion – The two groups performed identically.

Published: November 2004

Objectives:  This article aims to evaluate the habits of hygiene and usage of a sample group of Brazilian wearers of complete dentures.Design:  This study has a cross‐sectional design.Setting:  It was performed in the dental clinic of the University of Mogi das Cruzes.Subjects:  A sample group of 236 complete denture wearers was selected.Intervention:  The individuals were interviewed and clinically examined.Main outcome measures:  Most commonly used hygiene habits were assessed and recorded. Possible relationships between habits and oral conditions were also assessed.Results:  Dental treatment was sought by 43.6% 10 years after their last dental appointment, 77.5% declared they had been given no instructions regarding the hygiene of their dentures, only 22.9% said they had been instructed about oral hygiene, and 91.9% stated they had not been told to return for periodical review visits. Denture stomatitis was found in 42.4%, although 89% of these patients presented with no symptoms; 98.7% of the group brushed their dentures; 27.1% regularly immersed their dentures in chemical products; 26.3% removed their dentures overnight. A positive relationship was observed between the lack of recommendations regarding oral and denture cleansing and the presence of denture‐related stomatitis and hyperplasia. Family income and periodicity of visits to the dentist were also found to be related.Conclusion:  Mechanical cleaning is the most prevalent method of hygiene. Self‐reported lack of guidance to oral care was statistically related to inflammatory oral conditions. Future research is necessary to clarify possible causal role between these factors.

Published: November 2004

Objectives:  This study evaluated the impact of a community‐based oral health promotion programme on the use of oral health services, oral health knowledge, attitudes, and practices of older Greek and Italian adults attending community clubs and living in Melbourne, Australia.Methods:  The oral health promotion intervention consisted of three components: a series of oral health seminars, held at the clubs in the participants’ native languages, the provision of oral health care products, and the production of oral health information sheets. The intervention programme was known as the Oral Health Information Seminars/Sheets (ORHIS). The content of each session was determined following suggestions and findings from the data collected.A pre‐test–post‐test non‐equivalent control group quasi‐experimental design was chosen to evaluate the intervention. A total of 520 independent‐living older adults, members of Greek or Italian social clubs participated in this evaluation.Results:  Participants who took part in the intervention responded with higher levels of achievement than those in the control groups. After controlling for baseline variables, experimental groups were significantly more likely than the control groups at post‐test to have improved oral health attitudes, oral health knowledge, and self‐assessed physical health status, as well as, self‐reported oral hygiene practices and use of oral health services.Discussion:  The ORHIS approach was successful within the setting of social clubs, and highly acceptable to these communities. As such, it represents a helpful approach for the design of (oral) health interventions in older adults. Further research is required to test the long‐tem impact including the economic evaluation of the ORHIS approach.
Radiological imaging to improve the emergency department diagnosis of acute appendicitis
Authors: Rosengren David , Brown Anthony FT , Chu Kevin 
Published: November 2004

AbstractObjectives:  To determine the institution's current non‐therapeutic (negative) appendicectomy rate; the frequency of clinical predictors for appendicitis in patients who underwent appendicectomy; and the utilization and accuracy of ultrasound scans (USS) and computed tomography (CT) in the diagnosis of appendicitis.Methods:  A retrospective chart review was conducted in an adult, metropolitan teaching hospital. Patients who presented to the ED and underwent an appendicectomy over a 12‐month period were analysed. Symptoms and signs predictive of appendicitis, results of USS and CT scans if performed, and histopathology findings were abstracted from patient records.Results:  Two hundred and forty patients had appendicectomies, 147 (61%) were male and the median age was 25 years (range 14–78 years). The negative appendicectomy rate was 14.3% (95% CI 9.1–21.0%) and 18.3% (95% CI 11.0–26.7%) in males and females, respectively. Abdominal pain shifting to the right iliac fossa (RIF), anorexia and RIF rebound tenderness were found more frequently in patients with positive than negative appendicectomies (P < 0.05). USS and CT scans were performed in 68 (28%) and 15 (9.5%) patients, respectively. The likelihood ratio for appendicitis in patients with a normal USS or a normal CT scan was 0.83 (95% CI 0.56–1.24) and 0.08 (95% CI 0.01–0.60), respectively. There were no false positive CT scan results.Conclusion:  Computed tomoraphy scanning should play an increasing role in the ED management of suspected appendicitis. Our negative appendicectomy rate could potentially be halved by the introduction of CT scans in the diagnostic work up of these patients.
Epistaxis
Authors: M Middleton Paul 
Published: November 2004

AbstractEpistaxis is a frequent complaint, and may often cause great anxiety in patients and clinicians. Epistaxis results from the interaction of factors that damage the nasal mucosal lining, affect the vessel walls, or alter the coagulability of the blood, and which may be categorized into environmental, local, systemic and medication related. The knowledge of the first aid treatment of epistaxis is very poor, amongst not only the public, but also health professionals. Immediate emergency department management of epistaxis depends on prioritized assessment and treatment, including resuscitation if necessary, together with the application of relatively simple otolaryngological techniques. There is little high quality evidence regarding routine, alternative or adjunctive treatments.
Medical support for Adventure Racing
Authors: Greenland Keith 
Published: November 2004

AbstractAdventure Racing has recently become a popular sport. In the past medical and paramedical staff were frequently positioned at checkpoints throughout the course of the race. Presently there is a developing role for appropriately qualified individuals to access the course by biking, running or swimming and then providing injured racers with on‐site first aid prior to their transfer to the nearest medical checkpoint. These medical staff should have not only appropriate first aid skills but also rock rescue techniques, rappelling and other basic rope work as well as be athletically fit. This article explores the new role and attempts to outline what characteristics may be required.

Published: November 2004

AbstractTheca lutein cysts (hyperreactio luteinalis) are benign cysts usually associated with molar pregnancy. We report a case of bilateral theca lutein cysts with normal intrauterine singleton pregnancy presenting as an acute abdomen requiring surgical intervention. Laparotomy revealed bilateral theca lutein cysts one of which was torted, necessitating salpingo‐ovariotomy.
Investigation of marmoset hybrids <i>(Cebuella pygmaea</i> × <i>Callithrix jacchus)</i> and related Callitrichinae (Platyrrhini) by cross-species chromosome painting and comparative genomic hybridization

Published: November 2004

We report on the cytogenetics of twin offspring from an interspecies cross in marmosets (Callitrichinae, Platyrrhini), resulting from a pairing between a female Common marmoset (<i>Callithrix jacchus</i>, 2n = 46) and a male Pygmy marmoset (<i>Cebuella pygmaea</i>, 2n = 44). We analyzed their karyotypes by multi-directional chromosome painting employing human, <i>Saguinus oedipus</i> and <i>Lagothrix lagothricha</i> chromosome-specific probes. Both hybrid individuals had a karyotype with a diploid chromosome number of 2n = 45. As a complementary tool, interspecies comparative genomic hybridization (iCGH) was performed in order to screen for genomic imbalances between the hybrids and their parental species, and between <i>Callithrix argentata</i> and <i>S. oedipus</i>, respectively. These genomic imbalances were confined to centromeric and telomeric heterochromatin, while euchromatic chromosome regions appeared balanced in all species investigated. When comparing marmosets and tamarins, sequence divergence of centromeric heterochromatin was already clearly noticeable. In the <i>C. argentata</i> and <i>C. pygmaea</i> genomes numerous subtelomeric regions were affected by amplification of different repetitive sequences. Cross-species FISH with a microdissection-derived <i>C. pygmaea</i> repetitive probe revealed species specificity of this repetitive sequence at the molecular cytogenetic level of resolution.
South China Sea Wind-Wave Characteristics. Part I: Validation of Wavewatch-III Using TOPEX/Poseidon Data

Published: November 2004

Abstract
A full-spectral third-generation ocean wind-wave model, Wavewatch-III, has been implemented in the South China Sea (SCS) for investigating wind-wave characteristics. This model was developed at the Ocean Modeling Branch of the National Centers for Environmental Prediction (NCEP). The NASA QuickSCAT data (0.25° resolution) 2 times daily were used to simulate the wind waves for the entire year of 2000. The significant wave heights from Wavewatch-III are compared to the TOPEX/Poseidon (T/P) significant wave height data over the satellite crossover points in SCS. The model errors of significant wave height have Gaussian-type distribution with a small mean value of 0.02 m (almost no bias). The model errors are comparable to the T/P altimeter accuracy (0.5 m) in the central SCS and are smaller than the T/P altimeter accuracy in the northern and southern SCS, which indicates the capability of Wavewatch-III for SCS wave simulation.

Published: November 2004

Abstract
A novel manganiferous coordination polymer, [Mn(II)(HL)2]n (H2L = 4-hydroxynicotinic acid) (1) was hydrothermally synthesized. Interestingly, an in situ ligand synthesis for HL from 3,4-pyridinedicarboxylic acid precursor was observed. Structure analysis indicates 1 is built up from building blocks of Mn(II)-centered octahedron and HL ligand. The μ3-HL ligand plays dual roles for the formation of 1-D framework: chelate and bridge.
