This study investigated allergy immunotherapy potential of Lactobacillus paracasei L9 to prevent or mitigate the particulate matter 2.5 (PM2.5) enhanced pre-existing asthma in mice. Firstly, we used a mouse model of asthma (a 21-day ovalbumin (OVA) sensitization and challenge model) followed by PM2.5 exposure twice on the same day of the last challenge. PM2.5 was collected from the urban area of Beijing and underwent analysis for metals and polycyclic aromatic hydrocarbon contents. The results showed that PM2...

Both metal allergy and dental focal infection have been considered as causative factors for palmoplantar pustulosis, and several case reports described that the skin lesions were ameliorated after dental metal removal or dental infection control. However, limited data are available to evaluate the association of these factors with disease severity of palmoplantar pustulosis. This study is designed to analyze the clinical outcome of 85 palmoplantar pustulosis patients after dental infection control (n = 70), tonsillectomy (n = 6) and dental metal removal (n = 9)...

BACKGROUND: Chromium coatings on metal alloys can be decorative, and prevent corrosion and metal ion release. We recently showed that handling of a chromium-containing disc resulted in chromium deposition on the skin. OBJECTIVES: To examine patch test reactivity to chromium-coated discs. METHODS: We included 15 patients: 10 chromium-allergic patients, and 5 patients without chromium allergy. All were patch tested with potassium dichromate, cobalt chloride, nickel sulfate, and nine different metallic discs...

Metal implants for osteosynthesis are nowadays standard in orthopedic and trauma surgery. Steel implants, especially cerclages, bands and wires, can show more corrosion due to friction and lead to encapsulation in connective tissue with fluid borders even without loosening. Corrosion and fluid borders are potentially more susceptible to incompatibility and infections. Titanium implants have the advantage of better allergic compatibility. Problems may occur in material removal, especially with titanium implants because material fractures occur more frequently...

Nickel is the most frequent allergen in patients with allergic contact dermatitis and nickel allergy has been associated with recurrent in-stent restenosis. However, it is often misdiagnosed because of a low suspicion threshold. It should be discarded in patients with recurrent in-stent restenosis, especially if their medical history reveals prior contact dermatitis. It is also noteworthy and rarely specified that even newer generation stents that use novel metal alloys also contain low amounts of nickel. To avoid the implantation of new stents containing this metal, when percutaneous coronary intervention is indicated, drug eluting balloons or bioresorbable vascular scaffolds associated with small doses of steroids could provide good alternatives of treatment...

INTRODUCTION: Hypersensitivity to implants is a rare complication of total knee arthroplasty (TKA). Metal and, less frequently, bone cement can produce allergic symptomatology that if unresponsive to conservative treatment could lead to revision. MATERIALS AND METHODS: We present the case of a patient with generalized pruritus and metal taste starting during the first postoperative month after TKA. Dermal allergy exams revealed that the patient had hypersensitivity to nickel sulphate and cobalt chloride and bone cement...

Hypersensitivity reactions to implants in orthopaedic and trauma surgery are a rare but devastating complication. They are considered as a delayed-type of hypersensitivity reaction (type IV), characterized by an antigen activation of sensitized T-lymphocytes releasing various cytokines and may result in osteoclast activation and bone resorption. Potential haptens are originated from metal alloys or bone-cement. A meta-analysis has confirmed a higher probability of developing a metal hypersensitivity postoperatively and noted a greater risk of failed replacements compared to stable implants...

Despite decades of titanium as the gold standard in oral implantology, the search for alternatives has been growing. High esthetic standards and increasing incidence of titanium allergies, along with a rising demand for metal-free reconstructions, have led to the proposal of ceramics as potential surrogates. Following numerous experimental studies, zirconium dioxide (zirconia) has earned its place as a potential substitute for titanium in implantology. Yet, despite zirconia's excellent biocompatibility and tissue integration, low affinity to plaque and favorable biomechanical properties, early failures were significantly higher for zirconia implants than for titanium implants...

REVIEW
Wendy Z W Teo, Peter C Schalock
Total hip and knee replacement surgery using metal alloy devices is common. Type IV allergic reactions to these implants occur, though infrequently. While uncommon, peri-implant metal allergic reactions may cause significant morbidity for the affected individual-including aseptic loosening, pseudotumor formation and frank device failure. It is challenging to predict who will have these reactions, even in those with established pre-implant metal allergy. At this time, the scientific literature clearly supports few conclusions...

Urban particulate matter (PM) is associated with an increase in asthma. PM2.5 (<PM2.5 μm) and coarse PM (CPM: PM2.5-PM10 μm) were collected from the air in a Chinese city during haze events. The amounts of polycyclic aromatic hydrocarbons (PAHs) were higher in PM2.5 than in CPM. Conversely, microbial elements LPS and β-glucan were much higher in CPM than in PM2.5. Concentrations of Si, Al, Fe, and Ti in CPM were greater than in PM2.5, while Pb, Cu and As concentrations were lower than in PM2.5. When RAW264...

INTRODUCTION: Allergic and inflammatory reactions have commonly been associated with the release of metal ions during orthodontic treatment. Our objective was to evaluate prospectively gingival and blood status in patients allergic to nickel. METHODS: Allergy to nickel was diagnosed using a patch test. Two groups were established: conventional braces (n = 21) and nickel-free braces (n = 21). The gingival index was used to determine gingival status before treatment, periodically for 12 months (evaluations every 3 months), and 1 month after the removal of the braces...

BACKGROUND: All implant compounds undergo an electrochemical process when in contact with biological fluids, as well as mechanical corrosion due to abrasive wear, with production of metal debris that may inhibit repair processes. None of the commonly-used methods can diagnose implant allergies when used singly, therefore a panel of tests should be performed on allergic patients as pre-operative screening, or when a postoperative metal sensitisation is suspected. METHODS: We analysed patients with painful prostheses and subjects prone to allergies using the Patch Test in comparison with the Lymphocyte Transformation Test...

Polybia paulista (Hymenoptera: Vespidae) is a clinically relevant social wasp that frequently causes stinging accidents in southeast Brazil. To date, diagnosis and specific immunotherapy (SIT) of allergy are based on the use of crude venom extracts. Production of recombinant forms of major allergens from P. paulista venom will improve diagnosis and SIT of allergic patients by reducing the incidence of cross-reactivity and non-specific sensitization. Here, we describe the molecular cloning, heterologous expression, purification and IgE-mediated immunodetection of phospholipase A1 (Poly p 1), a major allergen from P...

OBJECTIVE: Takotsubo syndrome (TS) is a heart condition characterised by a sudden transient left ventricular dysfunction; its pathophysiology is probably associated with elevated levels of catecholamines but the exact mechanism is not known as yet. Literature and clinical experience suggest that TS affects persons with various comorbidities. This pilot work aims to evaluate the frequency of comorbidities with potential pathological immune reactivity, and to evaluate the potential association between TS and hypersensitivity to metals assessed by LTT-MELISA®...

A 12-year-old boy with a past medical history of nickel allergy was referred to our service after sustaining an air rifle injury with a retained BB in his left inferior orbit. On examination, he had a palpable orbital mass and systemic urticaria. Plain films demonstrated a spherical metallic foreign body adjacent to the left inferior orbital rim. Given his worsening systemic reaction despite oral antihistamine therapy, decision was made to remove the foreign body. In the operating room, the Allergan Magna Finder-a prepackaged, sterile device normally used for retrieval of a port used in tissue expansion surgery-was placed over the inferior conjunctiva of the lower eyelid...

BACKGROUND: Literature data on the release of nickel and chromium from stainless steel cookware during food preparation are contrasting, have often been obtained with uncommon foods and/or procedures, and are thus not widely applicable. OBJECTIVES: To assess the release of nickel and chromium from 18/10 (grade 316) stainless steel pots in cooking conditions that are common in an urban lifestyle. METHODS: Tomato sauce and lemon marmalade were cooked for 1 h, alone or with added EDTA, in used or unused stainless steel pots from different manufacturers...

BACKGROUND: Both performer- and device-dependent variabilities have been reported in sizes of wheal responses to skin prick tests. OBJECTIVE: We aimed to evaluate whether or not variabilities in sizes of wheal responses influence the final interpretation of skin prick tests; in other words, the decision on whether or not there is an allergy to a given antigen. METHODS: Skin prick tests with positive and negative controls and extracts of Dermatophagoides farinae and Dermatophagoides pteronyssinus were done for 69 patients by two different persons, using two different puncturing devices- disposable 22-gauge hypodermic needles and metal lancets...
