Ochronosis is the blue-gray discoloration of collagen-containing tissues due to homogentisic acid (HGA) deposition, secondary to endogenous alkaptonuria or exogenous enzyme inhibition. In renal disease, accumulation of HGA in serum can cause methemoglobinemia. A 60-year-old woman with renal disease and anemia presented with 3 days of weakness and months of gray skin discoloration.

Background: Silver-containing dressings are considered to be safe even though there have been some reports of complications, including argyria and various organ system dysfunctions. Despite the widespread use of silver dressings, little research has been done regarding the absorption and toxicity of silver.
Objective: We aimed to study the systemic absorption of silver in patients with chronic inflammatory wounds and to determine associated factors of systemic silver absorption and evaluated its association with silver toxicity. Read More

Silver cutlery and serving dishes are a potential source of exposure of humans that was never quantified. Release of silver was assessed in vitro in an acidic solution mimicking food fluid in two conditions: i] the JRC guidelines for hot fill conditions with stable high temperature over a 2 hour-period of time, and ii] a more realistic condition with spontaneous progressive decline from 90̊C to ambient temperature over the same period of time. Massive silver 95% strips were exposed to a 5% citric acid solution: i) cooling down from 90̊C to ambient or ii) 70̊C maintained, during 2 hours. Read More

A biopsy specimen from the nasal mucosa of a 37-year-old man disclosed a subepithelial accumulation of black granules mainly running parallel to the surface in the absence of any inflammatory infiltrate. Since the mucosal pigment was negative with Perls' stain and resisted to melanin bleach, an exogenous pigmentation was suspected. The biopsy specimen had been taken because of a diffuse steel-blue pigmentation of the nasal mucosa, incidentally discovered during routine clinical examination. Read More

Implant-associated infections remain a major issue in orthopaedics and antimicrobial functionalization of the implant surface by antibiotics or other anti-infective agents have gained interest. The goal of this article is to identify antimicrobial coatings, for which clinical data are available and to review their clinical need, safety profile, and their efficacy to reduce infection rates. PubMed database of the National Library of Medicine was searched for clinical studies on antimicrobial coated implants for internal fracture fixation devices and endoprostheses for bone surgery, for which study design, level of evidence, biocompatibility, development of resistance, and effectiveness to reduce infection rates were analyzed.

Localized cutaneous argyria is a rare condition secondary to skin deposition of silver following exposure to substances containing this metal. The clinical appearance and dermoscopy findings require deep melanocytic lesions and particularly melanoma metastasis to be ruled out. Silver deposits are usually confirmed by scanning electron microscopy and/or energy-dispersive X-ray spectroscopy. Read More

Silver is commonly used as a disinfectant, and chronic exposure to silver may cause argyria, resulting in a gray-blue discoloration of human skin. However, the mechanism for cellular toxicity of silver has not been well explained. We studied the mode of cell death, the ratio of glutathione disulfide/glutathione, induction of metallothionein and activation of mitogen-activated protein kinases in J774. Read More

Introduction: Infection in megaprostheses remains an unsolved problem, with a rate of occurrence ranging from 5% to 12%. Silver coating of medical devices has recently been proposed to reduce infection rate because of the antibacterial effect of silver. This innovation could be particularly interesting for megaprostheses, but few data have been reported in the literature. Read More

Purpose: The aim of this report is to present a case of a patient, metal foundry worker, who had been exposed to industrial silver salts for over 20 years. It is well established that chronic exposure to silver compounds can cause accumulation of silver deposits in various tissues.

Background: Silver is a transition metal, toxic when ingested in significant amounts, causing argyria (skin deposition) and argyrosis (eye deposition). It is excreted mainly via the gastrointestinal tract with only small amounts eliminated by the kidneys, and rarely have cases of nephrotoxicity due to silver been reported. Here we present the case of a woman who used colloidal silver as an alternative remedy for a T cell lymphoma, who subsequently developed argyria and a pauci-immune crescentic glomerulonephritis with evidence of extensive glomerular basement membrane silver deposition.

Argyria is a condition characterized by pigmentary changes secondary to exposure to silver salts and its accumulation in skin, mucous membranes and annexes, which typically produces blue or gray-blue spots. A case of a male patient 62 years old, previously healthy, who has a blue-gray hyperpigmentation on the face, trunk and upper extremity, affecting sun-exposed areas is presented. He admitted having ingested silver nitrate for 5 years at a rate of 1 bottle per week, with the intent to kill microorganisms in his body. Read More

Argyria is an uncommon blue-gray pigmentation of the skin (increased in sun-exposed areas), nail unit, and mucous membranes caused by prolonged silver exposure. Commonly occurs in the setting of occupational exposure, silver-containing medications, or systemic absorption from use of silver sulfadiazine on extensive burns/wounds. Recently, there appears to be an increase in the practice of colloidal silver ingestion given the popularity and easy availability of alternative medicines and dietary supplements containing various silver-containing compounds.

Diffraction is the process by which a beam of light is spread out as a result of passing through a narrow aperture or across an edge. Light diffraction can be produced by closing the aperture diaphragm beyond the recommended setting, by flipping the condenser cone down, or by using an opaque object such as the microscopist's hand to block the column of light and force it to bend around the edge. Any of these techniques results in greater refractility of objects in the path of the light. Read More

Silver has distinct antibacterial properties and has been used as a component of commercial products with many applications. An increasing number of commercial products cause risks of silver effects for human and environment such as the symptoms of Argyria and the release of silver to the environment. Therefore, the detection of silver in the aquatic environment is important. Read More

Argyria is a benign skin disease characterized by blue to slate-grey discoloration that is caused by deposition of silver granules in the skin and/or mucus membranes as a result of long-term ingestion of ionized silver solutions or exposure to airborne silver particles. The skin discoloration can be generalized or localized and is exacerbated by sunlight. The skin discoloration is usually permanent, and until recently, there has been no effective treatment for argyria. Read More

Argyria is a rare cutaneous condition due to dermal silver deposition leading to irreversible blue-grey discoloration. Acute radiation dermatitis (RD) is an expected toxicity in patients undergoing radiotherapy but it is unknown to what extent argyria affects the onset and severity of RD. We report a patient with argyria treated with concurrent chemoradiotherapy for Merkel cell carcinoma who experienced an unexpectedly brisk and severe RD during treatment. Read More
