AIM: The aim of this article is to describe the use of a titanium TSME appliance for patients with allergy to resin and nickel. We aim to highlight the optimal way to avoid problems such as stomatitis and peri-labial dermatitis, which generally appear in patients who use traditional orthodontic appliances made in acrylic resin and steel. MATERIALS AND METHODS: The construction of a titanium appliance is described and a case treated with it is reported. RESULTS: The titanium TSME presented in this paper has excellent biocompatibility due to its ability to form superficial oxides, which prevent oxidation and thus corrosion...

OBJECTIVES: A multitude of acrylic monomers is used in dentistry. Formaldehyde is a ubiquitous chemical agent, which is an ingredient of some dental materials and may be released from methacrylate-based composites. The purpose of the study is to evaluate the incidence and the risk of cross-sensitization to some methacrylic monomers (methylmethacrylate - MMA, triethyleneglycol dimethacrylate - TEGDMA, ethyleneglycol dimethacrylate - EGDMA, 2,2-bis-[4-(2-hydroxy-3-methacrylo-xypropoxy)phenyl]-propane - Bis-GMA, 2-hydroxy-ethyl methacrylate 2-HEMA, and tetrahydrofurfuryl methacrylate) and formaldehyde in students of dentistry, dental professionals and dental patients...

Contact dermatitis--irritant contact dermatitis, allergic contact dermatitis and protein contact dermatitis--are the most common occupational skin diseases, most often localized to the hands. Contact urticaria is rarer The main occupational irritants are wet work, detergents and disinfectants, cutting oils, and solvents. The main occupational allergens are rubber additives, metals (chromium, nickel, cobalt), plastics (epoxy resins, acrylic), biocides and plants. Diagnosis is based on clinical examination, medical history and allergy testing...

BACKGROUND: Forcipomyia taiwana (biting midge) allergy is the most prevalent biting insect allergy in Taiwan. An animal model corresponding to the human immuno-pathologic features of midge allergy is needed for investigating the mechanisms and therapies. This study successfully developed a murine model of Forcipomyia taiwana allergy. METHODS: BALB/c mice were sensitized intra-peritoneally with midge extract on days 0, 7, 14, 21 then intra-dermally on days 28, 31 and 35...

BACKGROUND: Patch test readings are usually performed on day 2 (48 hours) and day 4 (96 hours). However, reports in the literature identify delayed allergy to metals, corticosteroids, antibiotics, some preservatives, acrylic and methacrylic monomers and p-phenylenediamine. OBJECTIVES: The aim of our study was to identify the benefit of performing a day 7 (168 hours) reading to identify relevant late positive reactions. PATIENTS/METHODS/MATERIALS: Two hundred three consecutive patients were patch tested to the British Society for Cutaneous Allergy standard series with additional test series selected according to clinical history and applied at the same time...

STATEMENT OF PROBLEM: Adverse reactions to the materials used for the fabrication and reline of removable denture bases have been observed. PURPOSE: The purpose of this study was to systematically review the published literature on the cytotoxicity of denture base and hard reline materials. MATERIAL AND METHODS: MEDLINE via PubMed, Google Scholar, and Scopus databases for the period January 1979 to December 2009 were searched with the following key words: (biocompatibility OR cytotoxic* OR allergy OR "burning mouth" OR "cell culture techniques") AND ("acrylic resins" OR denture OR monomer OR relin* OR "denture liners")...

Rapid maxillary expansion (RME) in the initial stages of occlusal development has become a routine procedure in orthodontic practice. The increase of the transverse dimensions of the maxilla in the mixed dentition can be carried out by a rapid palatal expander that exploits primary teeth as anchorage to minimize any negative effects on permanent teeth. This case report demonstrates the use of a modified Haas-type RME appliance in a Caucasian girl 7 years 6 months of age with a maxillary transverse deficiency, unilateral crossbite, dental midline deviation, and maxillary anterior dental crowding...

OBJECTIVES: Although many survey reports on sick house syndrome have been published, few clinical studies have reported sick building syndrome (SBS) in Japan. We examined patients with SBS-like complaints by clinical observation and made environment measurements. METHODS: The subjects of our study were 11 office workers (2 men and 9 women) who visited our hospital because of poor physical condition after the construction and painting of a fireproof vault in their office...

BACKGROUND: Few US studies have reported results of patch testing with plastics and glues. OBJECTIVE: To report our institution's results of testing patients suspected of allergy to plastics and glues with a comprehensive plastics and glues series and to compare these results with previously published data. METHODS: Retrospective review of results of patch-testing with plastics and glues allergens at our institution between 2000 and 2007. In total, 444 patients were patch-tested with up to 56 plastics and glues allergens in the specialized series and up to five plastics and glues allergens in a baseline series...

BACKGROUND: Acrylic resin monomers, especially acrylates and methacrylates, are important occupational allergens. AIMS: To analyse patterns of concomitant patch test reactions to acrylic monomers in relation to exposure, and to suggest possible screening allergens. PATIENTS/METHODS: We reviewed the patch test files for the years 1994-2009 at the Finnish Institute of Occupational Health for allergic reactions to acrylic monomers, and analysed the clinical records of sensitized patients...

The aim of this study was to analyse leachable monomers, additives, and degradation products from polymer-based orthodontic base-plate materials. One heat-cured resin (Orthocryl), one light-cured (Triad VLC), and three thermoplastic materials (Biocryl C, Essix A+, and Essix Embrace) were investigated. Elution was performed in water at 37°C for 10 days. The extract medium was changed and analysed daily. Chromatographic methods were used to identify and quantify the leachables. In addition, the content of residual methyl methacrylate (MMA) was quantified in the poly(methyl methacrylate) (PMMA)-based materials...

INTRODUCTION: Contact dermatitis to cosmetics is a common problem in the general population, although its prevalence appears to be underestimated. We reviewed cases of allergic contact dermatitis to cosmetics diagnosed in our dermatology department over a 7-year period with a view to identifying the allergens responsible, the frequency of occurrence of these allergens, and the cosmetic products implicated. METHODS: Using the database of the skin allergy department, we undertook a search of all cases of allergic contact dermatitis to cosmetics diagnosed in our department from January 2000 through October 2007...

Histamine releasing and immunomodulating activity of the following dental restorative materials (DRM) - Prizmafil, Filtek Z250, XRV Herculite Prodigy, Glasiosite, Te-Econol, Valux Plus, Polofil Supra were studied. It was shown that DRM under study as a rule did not possess the ability to release histamine (H) from human blood basophile (BB) excluding Filtek Z250 which release H from BB in patients with allergy and sound donors. The studied DRM implanted under mouse skin were able to modulate immune response to the allergen, at that some of them increased antibodies of IgE-class forming and other suppressed immune response caused by IgG-antibody forming...

BACKGROUND: By definition, stomatodynia or burning-mouth syndrome involves oral pain with no causes being found on history taking or examination. An allergic origin is often suspected by doctors and patients alike. In this study, we attempted to assess the value of epicutaneous tests in demonstrating allergic causes for patients presenting stomatodynia. PATIENTS AND METHODS: This was a single-centre retrospective study of patients undergoing epicutaneous tests between 1996 and 2003 to screen for allergic causes of mouth pain not accounted for by any abnormalities seen during examination performed at consultations for mouth disease...

BACKGROUND: Facial lipoatrophy is defined as the reduction in buccal and orbital fat pads along with a more global loss of fat within the subcutaneous tissue. It is the most common and distressing sign of human immunodeficiency virus-associated lipodystrophy. Injectable polyacrylamide hydrogel (Aquamid) is a synthetic nonbiodegradable polymer consisting of a minor backbone of 2.5 percent cross-linked polyacrylamide and 97.5 percent nonpyrogenic water and is used for cosmetic facial contour correction...
