The development of pseudotumors is not uncommon with metal-on-metal total hip arthroplasty. Pseudotumors that dissect into the retroperitoneal space can cause symptoms of nerve compression. We describe a case of a 53-year-old male with a metal-on-metal total hip arthroplasty who developed mild symptoms of a femoral nerve neuropathy 6 years postoperatively. Revision arthroplasty to a ceramic-on-polyethylene articulation and debridement of the pseudotumor was performed. Postoperatively, the patient's femoral neuropathy progressed and a repeat magnetic resonance imaging showed an increase in size of the pseudotumor despite the removal of the offending metal-on-metal articulation...

BACKGROUND: There is a paucity of data examining metal ion levels over time. METHODS: We retrospectively reviewed 59 patients (69 hips) with an articular surface replacement total hip arthroplasty. We reviewed prerevision cobalt and chromium concentrations over time. RESULTS: Seventy-one percent of patients who were revised and had multiple ion measurements (12/17) demonstrated increasing cobalt ion levels or elevated ion levels over time...

Pigment-epithelium derived factor (PEDF) is a neurotrophic factor with neuroprotective, anti-tumorigenic, and anti-angiogenic effects. Elevated levels of PEDF have previously been proposed as a cerebrospinal fluid (CSF) biomarker for Alzheimer's disease. However, the origin of PEDF in CSF, i.e. whether it is derived from the brain or from the systemic circulation, and the specificity of this finding hitherto remained unclear. Here, we analyzed levels of PEDF in paired CSF and serum samples by ELISA in patients with Alzheimer's disease (AD, n=12), frontotemporal dementia (FTD, n=6), vascular dementia (n=4), bacterial meningitis (n=8), multiple sclerosis (n=32), pseudotumor cerebri (n=36), and diverse non-inflammatory neurological diseases (n=19)...

Fibro-osseous pseudotumor of the digits is a benign neoplasm that originates in the soft tissue adjacent to the short bones of the hands and feet. We present a case in a 13-year-old girl that was initially misdiagnosed as pyogenic granuloma. Familiarity with this entity and imaging and histologic studies are necessary to avoid incorrect diagnoses and aggressive surgical interventions.

Immunoglobulin G4-related disease (IgG4-RD) is a recently defined condition characterized by inflammatory tumefactive lesions in various organ systems. IgG4-RD is a clinical and radiological diagnosis of exclusion and requires the presence of specific histopathological criteria for diagnosis. A 50-year-old man presented to an outside hospital with a 3-month history of progressively worsening back pain and symptoms of pleurisy, nasal crusting, and hematochezia. Radiological workup revealed an epidural-paraspinal mass with displacement of the spinal cord, destruction of the T5-6 vertebrae, and extension into the right lung...

Recent concerns have emerged surrounding the toxicity that cobalt may represent when used in MOM implants. Owing to corrosion and wear of MOM implants, the subsequent released cobalt nanoparticles (CoNPs) or Co ions (Co(2+)) can cause adverse reactions, such as the generation of pseudotumors, extensive necrosis, early osteolysis, and implants failure. The present study confirmed that CoNPs and Co(2+) can induce dose- and time-dependent cytotoxicity with increasing reactive oxygen species (ROS) levels. Additionally, using metallothionein (MT), a heavy metal-binding protein, the present study assessed the protective effects of Zn(2+) against CoNPs and Co(2+)-induced cytotoxicity of RAW 264...

Inflammatory myofibroblastic tumors (IMT) were previously included in the "inflammatory pseudotumors" family, but have emerged as a distinct entity recently. The management of IMT may be challenging due to its intermediate malignant potential. We present a case of a young patient with an asymptomatic retroperitoneal mass with some imaging findings that could point to the IMT diagnosis pre-operatively. After two failed attempts to fully characterize the lesion by percutaneous and surgical biopsy, surgical resection was conducted and the final diagnosis was achieved...

Inflammatory pseudotumor (IPT) has always been considered a diagnostic challenge. Its rarity and resemblance to other more common pathological entities imposes that neither clinical nor radiological characteristics can lead to a definitive diagnosis. The surgical excision of the lesion is the ultimate approach for accurate diagnosis and cure. Moreover the true nature of IPT, its origin as a neoplastic entity or an over-reactive inflammatory reaction to an unknown trigger, has been a long debated matter. Surgery remains the treatment of choice...

BACKGROUND/AIMS: The diagnosis of cutaneous leishmaniasis (CL) is based on the microscopic detection of amastigote, isolation of the parasite, or the detection of Leishmania DNA. Nevertheless, since these techniques are time consuming and not usually available in many endemic countries, the diagnosis remains clinical. Consequently, such disease may be overlooked because of its similarity to other skin diseases. The aim of this study is to describe the clinical polymorphism of CL caused by Leishmaniamajor...

BACKGROUND: In critically ill patients with colonization/infection of multidrug-resistant organisms, source control surgery is one of the major determinants of clinical success. In more complex cases, the use of different tools for sepsis management may allow survival until complete source control. CASE PRESENTATION: A 42-year-old white man presented with traumatic hemorrhagic shock. Unstable pelvic fractures led to emergency stabilization surgery. Fever ensued with diarrhea, followed by septic shock...

BACKGROUND: The Birt-Hogg-Dubé (BHD) syndrome is a very rare autosomal dominant form of genodermatosis caused by germline mutations in the folliculin (FLCN) gene, which is mapped to the p11.2 region in chromosome 17. BHD commonly presents cutaneous fibrofolliculomas, pulmonary cysts, renal cell carcinoma, and recurrent pneumothoraxes. The disease is easily ignored or misdiagnosed as pneumothorax, pulmonary lymphangiomyomatosis (LAM), or emphysema. Follow-up and guidelines for managing recurrent pneumothoraxes in these patients are lacking...

The incidence of primary total elbow arthroplasty (TEA) in young patients is increasing. The indications for revision surgery are also rising. Here, we report a rare case of pseudotumor detected in a patient 16 years after TEA. Intraoperative findings revealed a necrotic mass characterized by a conspicuous metallosis in the soft tissues around the prosthesis, which caused ulnar nerve dislocation. Due to this anatomical change, a lesion of the nerve was accidentally produced during revision surgery. The case report emphasizes that the indications for elbow replacement, as well as the patient education about the permanent physical limitations, should be carefully considered...
