    Notes: We present a case of inflammatory epidermolysis bullosa acquisita (EBA) with IgA antibodies to plectin. Analysis of lesional skin biopsies by electron microscopy revealed the split level to be in the sublamina densa zone, corresponding to the diagnosis of EBA. Direct immunofluorescence of perilesional skin demonstrated u-serrated depositions of IgG and IgA that under immunoelectron microcopy were shown to be located in the sublamina densa. In contrast, indirect immunofluorescence on salt-split skin revealed circulating IgA antibodies that stained the roof rather than the floor of the blister. Immunoblotting showed these serum antibodies to be directed to the cytoplasmic hemidesmosomal antigen plectin. The antiplectin specificity of these antibodies was confirmed by ‘knockout’ immunofluorescence analysis; the serum IgA did not bind to skin sections of a patient with plectin-deficient epidermolysis bullosa. To our knowledge, this case demonstrates for the first time the existence of IgA antibodies against plectin.

    Notes: summary  The objective of the present study was to analyse the effects of implant supported overdentures on masticatory function in patients with an extremely resorbed mandible, and to compare the masticatory function in these patients using three differing types of implant treatment protocols. The mandibular overdentures were retained by a transmandibular implant, by four endosseous implants following augmentation of the mandible, and by four short endosseous implants, respectively. Sixty patients (50 women, 10 men, mean age 59·4 years) were randomly allocated to one of the three treatment groups. Masticatory function was assessed before and after treatment using a questionnaire, a masticatory performance test, and a structured interview. The patient-based masticatory function improved significantly. Concerning these parameters there were no significant differences between the three groups before and after treatment. A significant difference existed between the three groups for the laboratory-assessed masticatory function before treatment, but after treatment this difference was no longer significant. From this study it can be concluded that patients with an extremely resorbed mandible and functional complaints of their lower denture report significant improvement in masticatory function after implant-overdenture treatment. Differences in masticatory function between the three studied modalities were not significant after treatment.

    Five years of aftercare of implant-retained mandibular overdentures and conventional dentures (2002)

    Notes: The purpose of this multicentre randomized clinical trial was to analyse surgical and prosthetic aftercare and clinical implant performance of edentulous patients with implant-retained mandibular overdentures and of patients with conventional dentures, either or not after pre-prosthetic vestibuloplasty and deepening of the floor of the mouth. The evaluation period was 5 years. The implant systems evaluated were the IMZ implant system, the Brånemark implant system and the Transmandibular Implant system. The centre in Groningen had five groups (n=149) and the centre in Nijmegen had three groups (n=86). The evaluation comprised of surgical and prosthetic aftercare, together with clinical implant performance (CIP). The highest implant loss (29%) is found in the Transmandibular Implant group. All groups had prosthetic revisions and complications according to the CIP-scale. The majority of the patients in the endosseous implant groups were subject to minor complications. The CIP-score of the Transmandibular Implant group is significantly higher than the scores of the other groups, because of the high number of lost posts. In 26˙1% of the patients in this group score 4 is given, which means failure of the implant system. From this study it can be concluded that the endosseous implant systems used in this study have less surgical aftercare and a better clinical implant performance than the Transmandibular Implant system and are therefore the systems of choice for the edentulous mandible.

    A comparison of methods to assess marginal bone height around endosseous implants (1993)

    Notes: Abstract 3 methods of measurements of marginal bone level on intra-oral radiographs of endosseous implants are described: measurements with a computerized image analysis system, with a magnifying-glass and with a digital sliding gauge. The accuracy of each of these methods was investigated and compared. The intra- and inter-observer error analysis showed that determining the precise bone height on the image is responsible for a large standard deviation for each method. It is concluded that measurements with a digital sliding gauge are preferable because it is easy to put into practice, and in addition, accuracy matches the accuracy of the other methods.

    Notes: Abstract Measurement and description of the effects of extreme conditions on biological nitrite oxidation was the aim of this study, using Nitrobacter agilis (ATCC 14123) as a model nitrifying bacterium. The initial O2 consumption rate of a concentrated cell suspension was used as a rapid assay to measure the effects. Several relationships, based on Michaelis-Menten kinetics, were derived. These relationships describe the behaviour of N. agilis with respect to substrate inhibition, product inhibition and various salt concentrations up to 500 mmol · dm −3 with the pH ranging from 6.5 to 8.5. Substrate and product inhibition were pH-dependent and the substrate inhibition could be related to the undissociated nitrite. In contrast with previous reports on nitrite-oxidizing microorganisms, we did not observe severe inhibition by NH inf4 sup+ .

    Notes: Summary Nitrification of ammonia in concentrated waste streams is gaining a lot of attention nowadays. Nitrosomonas europaea is the predominant ammonia-oxidizing species in these environments. Prediction of the behaviour of a pure culture of N. europaea (ATCC 19718) under conditions prevailing in concentrated waste streams was the aim of this study. The initial oxygen consumption rate of a concentrated cell suspension was used as a rapid assay to measure the effects on N. europaea under various conditions. Several relationships, based on Michaelis-Menten kinetics, were derived. They describe the behaviour of N. europaea at substrate (NH4 +), product (NO2 − and K+, Na+, SO inf4 sup2− , NO3 −, Cl−) concentrations up to 500 mol/m3 and pHs ranging from 6.5 to 8.5. High concentrations of ions inhibited N. europaea but specific substrate inhibition was not observed. Product inhibition was strongly pH-dependent and severe inhibition was found at pH 6.5.

    A new porous polyetherurethane wound covering (1990)

    Notes: A polyetherurethane (PEU) wound covering with non-interconnected micropores up to approximately 5 μm has been prepared by means of a phase inversion process. This highly elastic, very thin (15-20 μm), pliable wound covering showed good, immediate adherence to wet wound surfaces and high water vapor permeability, but was impermeable to bacteria. In guinea pigs epidermal wound healing of partial-thickness wounds under PEU wound coverings was accelerated compared with uncovered controls and an occlusive wound covering, OpSite. Water in liquid form or wound exudate could not leak through the PEU covering, but its high water vapor permeability induced concentration of the wound exudate into a jellylike clot layer, which apparently accelerated reepithelialization. The main conclusion from a clinical study on 20 donor sites was that the use of the PEU covering reduced pain, besides prevention of fluid retention. No differences in epithelialization were seen in comparison to tulle gras-treated wounds.
