E-062 Cobalt platinum stent-assisted coil embolization of a basilar tip aneurysm in a patient with a titanium allergy
DiscussionTitanium allergy is an under recognized entity. Titanium allergies are documented in the literature, with proposed rates in the general population of 0.9-7.9%. Allergy to titanium oxides, as in our patient, is the rarest. Titanium is a component in nitinol-based devices in combination with nickel and surgical clips are also made of titanium. Thus, treatment options for wide necked aneurysms are limited. Allergic reactions to titanium are not well understood, but have been reported as type IV hypersensitivity reactions manifested as cutaneous rashes or delayed-onset in-stent stenosis in cardiac stenting. Neurologi...

Respiratory tract rather than cutaneous atopic allergy inversely associate with multiple sclerosis: A case–control study
Conclusions: There is a significant inverse association between RTA and MS that is compatible with a Th1/Th2 imbalance. History of RTA can be considered as a clinically useful risk reducing factor of MS.

Nickels and tines: the myth of nickel allergy in intracranial stents
Conclusions Nickel release from commonly used intracranial stents is negligible. These results suggest that previously reported hypersensitivity to these stents may be misattributed to nickel allergy, and that patients with nickel allergy may be safely treated with select nickel-containing stents.

Failure of facet replacement system with metal-on-metal bearing surface and subsequent discovery of cobalt allergy: report of 2 cases.
Abstract The aim of this study was to report on 2 patients in whom metal-on-metal (MOM) facet replacements failed, with subsequent positive findings on allergy testing. Motion-preserving devices have been used with limited success when instrumentation is indicated in the mobile spine. MOM-bearing surfaces in orthopedics were developed to increase implant longevity, yet have been associated with numerous adverse outcomes, including local tissue reactions, pseudotumors, metallosis, and the need for revision surgery. Five patients with spinal stenosis and low-grade spondylolisthesis were randomized to undergo facet r...

Cell-mediated allergy to cerebral aneurysm clip causing extensive cerebral edema.
Abstract The authors report the first case of vasogenic cerebral edema due to a cell-mediated hypersensitivity reaction to a nickel-containing aneurysm clip. The patient initially presented for elective clipping of a right middle cerebral artery aneurysm, and on long-term follow-up she demonstrated relapsing-remitting cerebral edema. Four years post-aneurysm clipping, she underwent an exploratory craniotomy given unsuccessful conservative management of her headaches and imaging evidence of cerebral edema with mass effect. During surgery, gross parenchymal edema and inflammatory nodules were observed. Histopatholog...

P-020 Non-Ischemic Cerebral Enhancing (NICE) Lesions Secondary to Endovascular Aneurysm Therapy: Nickel Allergy or Foreign Body Reaction? Reports of Two Cases and Review of the Literature
Delayed onset of non-ischemic cerebral enhancing lesions is a rare complication of intracranial aneurysms’ endovascular therapy (EVT). This complication has been attributed either to foreign body emboli and subsequent granulomatous reaction or cerebral hypersensitivity and nickel allergy. After retrospective review of all patients managed by EVT at our Institution from January 1st 2012 to December 31st 2014, 2 out of 374 patients (0.5%) with such a complication were identified. Patient # 1 developed non-ischemic cerebral enhancing (NICE) lesions 1 month after balloon assisted coiling of a ruptured anterior communicat...

Correspondence on "Nickels and tines: the myth of nickel allergy in intracranial stents" by Vanent et al
Dear Editor, Nickel hypersensitivity remains a hot issue, as endovascular interventions and implantation of devices gain more ground. The extent and the real incidence of nickel allergy secondary to device placement remain under investigation.1 A wide variety of clinical signs and symptoms have been described, depending on the area of device implantation.1 2 A recent meta-analysis supported that adverse events were increased in nickel-allergic patients after endovascular interventions.3 Against this context, we read with great interest the article by Vanent et al on nickel allergy in intracranial stents.4 We would like to ...

Dermatitis caused by metal allergy after coil embolization for unruptured cerebral aneurysm
We report a rare case of metal-induced dermatitis after coil embolization for cerebral aneurysm. A 51-year-old woman experienced a rash around the lips and neck 3 weeks after coil embolization. Judging from the clinical course and results of several patch tests, platinum coils were considered to have induced the dermatitis. Symptoms were relieved with administration of oral steroids. This represents the first report of metal-induced dermatitis after neuroendovascular treatment. The possibility of metal allergy was difficult to suspect preoperatively. However, early evaluation and referral are important when skin sympt...

Metal allergy hypersensitivity after posterior thoracic spinal fusion: A case report and review of the literature
CONCLUSION: Hypersensitivity to metal (i.e., metal allergy) should be considered before performing instrumented spinal fusions.PMID:35350829 | PMC:PMC8942188 | DOI:10.25259/SNI_1139_2021
