BACKGROUND In-stent restenosis (ISR) is the major limitation of percutaneous coronary stenting procedure. The elements like nickel, chromate and molybdenum are known to cause contact allergy. Hypersensitivity reaction, against these metal ions, may be one of the reasons of ISR. Cobalt chromium coronary stents, which are increasingly being used in percutaneous coronary interventions, have more n...

Allergic contact hypersensitivity to metals is a delayed-type allergy. Although various metals are able to induce an allergic reaction, nickel is the most frequent cause of metal allergy worldwide. The high prevalence of skin sensitization to that metal is the result of an ubiquitous exposure, being contained in different everyday things, such as detergents, cheap jewelry, cosmetics, coins, but...

Background. Metals are very frequent sensitizers causing contact allergy and allergic contact dermatitis worldwide; up-to-date data based on patch test results has proved useful for the identification of a problem. Objectives. In this retrospective study prevalence of contact allergy to metals (nickel, chromium, palladium, gold, cobalt, and titanium) in Lithuania is analysed. Patients/Methods. ...

Aim: The aim of the study was to analyse the trends of allergy to the 10 most frequent contact allergens and to assess ageand sex-dependent changes of the trends in patients examined in 1996-2009. Material and methods: 4433 patients underwent patch tests with a set of allergens containing: potassium dichromate, nickel sulfate, cobalt chloride, 4-phenylenediamine, formaldehyde, thiuram mix, merc...

Nickel sulphate more frequently determines allergic dermatitis due to contact (contact eczema); less known are nasal inflammation (rhinitis) and bronchial asthma caused by nickel sulphate. Sporadic cases, often related to patients' work have been reported in the literature. The research described herein refers to 20 patients presenting clear nickel allergy with rhinitis (associated in 11 cases ...

BACKGROUND Nickel allergy is frequent and cause morbidity and increased health care costs. OBJECTIVE The aim of this study was to determine the proportion of inexpensive earrings randomly purchased from stores and street markets in two capitals that gave positive dimethylglyoxime (DMG) test reactions and to determine whether the degree of nickel release was related to shop category. METHODS...

The aim of this study was to estimate the prevalence of life-style practices in adolescents and their association with nickel allergy. Upper secondary school pupils (n = 4,376; 15-23 years) were patch-tested for nickel aller-gy, follow-ing completion of a questionnaire (answered by 6,095). Almost 86% girls and 21% of boys reported piercing. More girls (6%) than boys (3%) had a tattoo. Twenty-si...

Nickel allergy is a cell-mediated immune response. Most cases of nickel allergy can be related to skin contact with nickel containing metallic items as buttons, suspenders, ear-ornaments etc. Epidemiological studies have shown a sensitization frequency of 20 percent in young females and 10 percent in the elderly. Two to four percent of males are sensitized. The biological significant parameter ...

We present the case of a patient who developed a full-body desquamating macular-papular, pruritic rash after endovascular placement of a popliteal artery nitinol stent for acute limb ischemia. The rash was resistant to high-dose steroid and immunosuppressive treatment and intensive topical treatment. Patch testing revealed nickel allergy. The stented arterial segment was removed, with significa...
