Argyria. Case Report

A 70-year-old male rural worker was referred to our clinic with widespread grey pigmentation of the skin and nails. The condition had been asymptomatic for its entire duration (5 years). He reported past intranasal application of 10% Silver Vitellinate. A skin biopsy was performed and histology corroborated the clinical diagnosis of Argyria. This case represents a currently rare dermatological curiosity. Although silver colloids and salts have been withdrawn and/or banned by some drug surveillance agencies, they continue to be freely sold and unregulated as food supplements and as ingredients in alternative medicines, thereby risking the emergence of new cases of silver poisoning.

A Review of National Guidelines for Management of COPD in Europe

The quality of care can be improved by the development and implementation of evidence-based treatment guidelines. Different national guidelines for chronic obstructive pulmonary disease (COPD) exist in Europe and relevant differences may exist among them.This was an evaluation of COPD treatment guidelines published in Europe and Russia in the past 7 years. Each guideline was reviewed in detail and information about the most important aspects of patient diagnosis, risk stratification and pharmacotherapy was extracted following a standardised process. Guidelines were available from the Czech Republic, England and Wales, Finland, France, Germany, Italy, Poland, Portugal, Russia, Spain and Sweden. The treatment goals, criteria for COPD diagnosis, consideration of comorbidities in treatment selection and support for use of long-acting bronchodilators, were similar across treatment guidelines. There were differences in measures used for stratification of disease severity, consideration of patient phenotypes, criteria for the use of inhaled corticosteroids and recommendations for other medications (e.g. theophylline and mucolytics) in addition to bronchodilators.There is generally good agreement on treatment goals, criteria for diagnosis of COPD and use of long-acting bronchodilators as the cornerstone of treatment among guidelines for COPD management in Europe and Russia. However, there are differences in the definitions of patient subgroups and other recommended treatments.

Thoracic Duct Decompression for Protein-Losing Enteropathy in Failing Fontan Circulation

An infrequent but devastating late complication of Fontan circulation is protein-losing enteropathy (PLE), which results from unbalanced lymphatic homeostasis. Surgical decompression of the thoracic duct by redirecting its drainage to the pulmonary venous atrium has been introduced recently as a possible treatment. This report describes a single-institution experience with this innovative procedure in 2 patients with failing Fontan circulation with PLE refractory to optimized medical therapy.
